There are many types of elevators like hydraulic elevator, Pneumatic vacuum elevator, mine shaft elevator etc. Freight elevator is an elevator which carries freight. A  freight elevator  is used to do just what its name implies: to elevate, or lift,  freight, or goods. Don’t waste time! Our writers will create an original "Designing A Freight Elevator For The Movement Of Goods Business Essay" essay for you Create order It is built to carry goods rather than people. The smallest freight elevators are often called dumbwaiters. They are typically used in two-story buildings to move household goods such as laundry or dishes up and down. Though older versions were operated by pulling on a rope, modern dumbwaiters include a small electric motor. A heavy-duty freight elevator can hold a truck and can handle as much as 100,000 pounds using a dual rope system for support  [2] In this activity, we will first explore a possible model for the motion of a heavy-duty freight elevator used to raise and lower equipment and minerals in a mineshaft. We will evaluate the model for its strengths and weaknesses and then create a set of specifications to develop a model of our own. Analyzing a possible model: The possible model y = 2.5t3 15t2 represents the position of the elevator. Here y is in meters and is the vertical displacement. Here y = 0 when the elevator is at ground level. t is time in minutes and the starting time t = 0 minutes. The trip up and down the shaft, ignoring time spent at the foot of the shaft, is approximately six minutes and that the depth of the shaft is no more than 100 meters. I will use graphing software Graph 4.3 to visualize the motion of the elevator in the shaft which is shown below. displacement.png Graph : Displacement graph using the given model function I have calculated the position of the elevator at different time intervals which I have shown in the table below: Time t (minutes) Displacement (meters) 0 0.0 1 -12.5 2 -40.0 3 -67.5 4 -80.0 5 -62.5 Table : Displacement I have calculated the maximum and minimum displacement during the round trip of the elevator. The maximum / minimum d isplacement of the freight elevator during the round trip will be when the slope of the displacement function = 0 that is when velocity v = 0 Therefore = 7.5t2 30t = 0 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ ¡Ãƒ ¢Ã¢â€š ¬Ã¢â€ž ¢ t = 0 or 4 minutes. Therefore y (0) = 2.5(0)3 15(0)2 = 0 y(4) = 2.5(4)3 15(4)2 = -80 meters. Hence maximum displacement, ymax = 0 and minimum displacement, ymin = -80 meters. From the above table and graph we can observe the following facts. At time t = 0 and 6 minutes, the displacement is 0. This indicates that the elevator is at ground level at the start and the end of the round trip. Throughout the round trip, from t = 0 to 6 minutes, the displacement is negative. This indicates that the elevator is below the ground level which is evident from the graph also. The elevator descends to a maximum depth of 80 meters which is the ymin value at time t = 4 minutes. The time taken by the elevator to descend the maximum depth of 80 meters is 4 min utes whereas the time taken to ascend the same distance is 2 minutes. Since displacement y(t) = 2.5t3 15t2 meters We know that velocity is rate of change of displacement. Therefore Velocity = = y'(t) = 7.5t2 30t meters/minute Using graphing software I have graphed the velocity function which is shown below. velocity.png Graph : Velocity graph using the given model function I have calculated the velocity of the elevator at different time intervals which I have shown in the table below: Time t (minutes) Velocity v (meters/minute) 0 0.0 1 -22.5 2 -30.0 3 -22.5 4 0.0 5 37.5 6 90.0 Table : Velocity I have calculated the maximum and minimum velocity during the round trip of the elevator. The maximum / minimum velocity of the freight elevator during the round trip will be when the slope of the velocity function = 0 that is when acceleration a = 0 Therefore =15t 30 = 0 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ ¡Ãƒ ¢Ã¢â€š ¬Ã¢ „ ¢ t = 2 minutes. Therefore velocity is minimum at t = 2 minutes. v(2) = 7.5(2)2 30(2) = -30 meters / minute Since = 15. Therefore v is minimum at t = 2 minutes. v(2) = 7.5(2)2 30(2) = -30 meters/minute Therefore the minimum velocity of the elevator during the round trip is -30 meters/minute. From the above table and graph we can observe the following facts. When t = 0 and 4 minutes, the velocity is 0 meters/minute. It indicates that the elevator is at rest at the bottom of the shaft and at the ground level when it starts descending. During time interval 0 to 4 minutes the velocity is negative. This indicates that the elevator is moving downwards. During time interval 4 to 6 minutes, the velocity is positive. This indicates that the elevator is moving upwards. The minimum velocity is -30 meters/minute at time t = 2 minutes. We know that acceleration is rate of change of velocity. Therefore, Acceleration = = y(t) = 15t 30 meters/minute2 Using graphing software I have graphed the acceleration function which is shown below. accn.png Graph : Acceleration graph using the given model function I have calculated the acceleration of the elevator at different time intervals which I have shown in the table below: Time t (minutes) Acceleration (meters/minute2) 0 -30.0 1 -15.0 2 0.0 3 15.0 4 30.0 5 45.0 Table : Acceleration From the above table and graph we can observe the following facts. When t = 2 minutes, the acceleration is 0 whereas before t = 2 minutes it is negative and after t = 2 minutes it is positive. This indicates that the acceleration is changing its direction at time t = 2 minutes. During time interval t = 0 to 2 minutes, the acceleration is negative. This indicates that acceleration is in the downward direction. During time interval t = 2 to 6 minutes, the acceleration is positive. This indicates that acceleration is in the upward direction. I have graphed all the three displacement, velocity and acceleration functions together for comparison which is shown below. displ,vel.accn together.png Graph : Displacement, Velocity and Acceleration graphs using the given model function I have also combined all the values of displacement, velocity and acceleration at different time intervals for a comparative study as shown below. Time t (minutes) Displacement (meters) Velocity v (meters/minute) Acceleration a (meters/minute2) 0 0.0 0.0 -30.0 1 -12.5 -22.5 -15.0 2 -40.0 -30.0 0.0 3 -67.5 -22.5 15.0 4 -80.0 0.0 30.0 5 -62.5 37.5 45.0 6 0.0 90.0 60.0 Table : Displacement,velocity and acceleration. I have analyzed all the three displacement, velocity and acceleration together during the three time intervals as below. Between 0 to 2 minutes. During this time interval at t = 0 minutes, the displacement is 0 meters and a t time t = 2 minutes, the displacement is -40 meters. This indicates that the elevator is at ground level at the starting of the time interval and descends 40 meters by the end of this time interval which is also the half of the downward displacement of the elevator. During this time interval at t = 0 minutes, the velocity is 0 meters/minute and at time t = 2 minutes, the velocity is -30 meters/minute which is the minimum velocity of the elevator in the full trip. In this time interval the magnitude of the velocity is increasing. The negative values of velocity indicate that the elevator is moving downwards. During this time interval at t = 0 minutes, the acceleration is -30 meters / minute2 and at time t = 2 minutes, the acceleration is 0 meters / minute2. This indicates that the magnitude of the acceleration is decreasing in this time interval. In this time interval, the direction of both velocity and acceleration is same and downwards hence the acceleration helps the ele vator to speed up and the magnitude of the velocity increases. Between 2 to 4 minutes. During this time interval, at t = 4 minutes, the displacement is -80 meters. This indicates that the elevator is at the bottom of the round trip at the end of the time interval. Therefore during this interval of 2 to 4 minutes; the displacement is -40 meters. The elevator descends 40 meters during this time interval which is also the half of the downward displacement of the elevator. During this time interval at t = 2 minutes, the velocity is -30 meters/minute and at time t = 4 minutes, the velocity is 0 meters/minute. Therefore the elevator reaches its lowest point of the trip at time t = 4 minutes. In this time interval the magnitude of the velocity is decreasing. The negative values of velocity indicate that the elevator is moving downwards. During this time interval at t = 2 minutes, the acceleration is 0 meters / minute2 and at time t = 4 minutes, the acceleration is 30 meters/min ute2. This indicates that the magnitude of the acceleration is increasing in this time interval. The acceleration is positive during this time interval which indicates that the acceleration is upwards. In this time interval, both velocity and acceleration are in opposite direction. The acceleration is in the upward direction whereas the velocity is in downwards direction and the magnitude of the velocity is decreasing during this time interval. This indicates that, when the acceleration is in the opposite direction of the velocity, the velocity decreases. Between 4 to 6 minutes. During this time interval, at t = 6 minutes, the displacement is 0 meters. This indicates that the elevator is at the bottom of the round trip at the starting of the time interval and is at the ground level at the end of this time interval. Therefore during this interval of 4 to 6 minutes; the displacement is 80 meters. The elevator ascends 80 meters during this time interval which is the full ascen ds of the elevator. Therefore the elevator takes only 2 minutes to move from the lowest point of the trip to the ground level. During this time interval at t = 4 minutes, the velocity is 0 meters/minute and at time t = 6 minutes, the velocity is 90 meters/minute. The velocity is positive during this time interval and the elevator is moving upwards. Therefore the elevator reaches the ground level again at time t = 6 minutes and completes its trip. In this time interval the magnitude of the velocity is increasing. During this time interval at t = 4 minutes, the acceleration is 30 meters / minute2 and at time t = 6 minutes, the acceleration is 60 meters/minute2. This indicates that the magnitude of the acceleration is increasing in this time interval. The acceleration is positive during this time interval which indicates that the acceleration is upwards. In this time interval, both velocity and acceleration are in the same direction. Both the velocity and acceleration are in t he upward direction. The magnitude of the velocity is increasing during this time interval. This indicates that, when the both velocity and acceleration are in the same direction, the magnitude of the velocity increases. Conclusion: When both the velocity and accelerations are of the same sign that is they are in the same direction. The acceleration helps velocity and the magnitude of the velocity increases. When the velocity and the accelerations are of different signs that is they are in the opposite directions. The acceleration acts as retardation and decreases the magnitude of the velocity. Usefulness of the model function: The possible model function y = 2.5t3 15t2 models the complete round the trip motion by a single function. Problems in the model function: The main drawback of the given model function is that the elevator does not come to rest at the end of the trip when it returns back to the ground level. The velocity is 90 meters/minute at t = 6 minutes whereas the velocity should be 0 meters/minute. As per the model function, the elevator takes 4 minutes to descend to the bottom and only 2 minutes to ascend back to the ground level. This indicates that it takes double the time in descend compared to the time required to ascend. Since this is a vertical motion and gravitational force provides a gravitational acceleration downwards which always helps any object to move downwards and opposes any object to move upwards. Therefore the gravitational acceleration is helping the elevator while descending and opposing the elevator while ascending but the elevator takes half the time while ascending which means that the source of force required to take the elevator up has to be more powerful. This increases the cost of the equipment and operation. Using this model function the elevator can descend only up to a depth of 80 meters whereas the depth of the mineshaft is 100 meters. So the elevator can never reach the bottom of the mine shaft using this model function. Creating our own model: I tried to gather information for the speeds of freight elevators from the internet. The speeds of the heavy duty freight elevators manufactured by Hitachi Ltd., Japan are 30, 45 metres/minute.  [3] I have selected the maximum speed of freight elevator for my model as 45 meters/minute. Therefore the specification for redesigned freight elevator model is: The depth of the mine shaft the freight elevator has to descend is 100 metres. The maximum speed of the freight elevator is 45 metres/minute. The freight elevator takes equal time in descending and ascending from ground level to the depth of the mine shaft. The speed of the freight elevator is 0 meters/minute at the ground level, whether the freight elevator is starting from or reaching the ground, and at the bottom of the shaft. Looking at the above specifications, especially The freight elevator takes equal time during descending and ascending, which means that the displacement function graph is symmetri cal during ascend and descend. The elevator velocity is zero at the beginning, middle and at the end of the trip. The function which can suit the above requirements can be a sinusoidal cosine function. The cosine function starts from the maximum value 1 and ends at the maximum value 1. Also the cosine function is at its lowest value -1 at the middle of its cycle. Also the slope of the cosine function at these three points is zero and is symmetrical; hence it satisfies all the requirements of the model function. Therefore I will try a cosine function. The general cosine function is given by y(x) = A cos (Bx + C) + D. Here, A is the amplitude of the cosine function which is the difference between the peak and mean of the maximum and minimum y coordinates. B is given by B = where T is the time period and is the distance between the two successive maxima or minima. C is the horizontal translation of a normal cosine graph. This is negative when the graph is transl ated to the right and is positive when the graph is translated to the left. Its value is the horizontal shift of the point cosine (0) from the origin (0, 0). D is the vertical translation of the mean of the normal cosine function given by the mean of maxima and minima of y value. D is negative when the graph is translated downwards and is positive when the graph is translated upwards. Since I have taken the maximum depth of descend of the elevator to be 100 meters from the ground level. Therefore ymax = 0 and ymin = -100, therefore Amplitude, A= = 50 B = Horizontal translation, C = 0 Vertical translation, D = Substituting these values of A, B, C and D in the general equation of the cosine function I get the model displacement function as below: y(t) = = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦.(1) Therefore , Velocity v = = and, ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦..(2) Acceleration a = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦(3) Now in the above model equations the only unknown is the time period or we can say the time required for the elevator one round trip. In our specification of the model function I have specified that the maximum magnitude of the velocity of the elevator will be 45 meters/minute. Now the velocity v can be maximum when sin = -1. Therefore maximum velocity, Vmax = = 45 meters/minute Therefore T = 6.98 minutes. Therefore our model displacement, velocity and acceleration functions will be Displacement, y(t) = meters Velocity v(t) = meters/minute Acceleration a(t) = meters/minute2 I have graphed the above model functions for visual check. cosine displ.bmp Graph : Remodeled displacement graph cosine velocity.bmp Graph : Remodeled velocity graph cosine accn.bmp Graph : Remodeled acceleration graph I have calculated the values of displacement, velocity and acceleration at different time intervals which is shown in the table below.

The elevator descends a depth of 100 meters at t = 3.49 minutes which is half of the time taken for round trip. Therefore the elevator descends to the bottom of the mine shaft. The displacement graph is symmetrical and the time required for descend and ascend is 3.49 minutes which means that the elevator takes equal time in descend as well as ascend. The remodeled function is single function, which take cares of all the drawbacks of the original model function. Hence I accept this remodeled function as my final model function. I will modify my remodel functions for a high speed passenger elevator. From the same web site of Hitachi limited, I gathered that the speed of passenger elevators is 180, 210 and 240 meters/minute. I will design a displacement, velocity and acceleration function for a passenger elevator with the following specification. The height the passenger elevator has to ascend is 240 meters and the maximum speed of the elevator is 240 meters/minute. Using this specification, I will remodel my function as below. Amplitude, A= = 120 B = Horizontal translation, C = Vertical translation, D = Substituting these values of A, B, C and D in the general equation of the cosine function I get the model displacement function as below: y(t) = = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦.(1) Therefore, Velocity v = = and, ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚ ¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦..(2) Acceleration a = ÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ÃƒÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦(3) Now in the above model equations the only unknown is the time period or we can say the time required for the elevator one round trip. In our specification of the model function I have specified that the maximum magnitude of the velocity of the elevator will be 240 meters/minute. Now the velocity v can be maximum when sin = 1. Therefore maximum velocity, Vmax = = 240 meters/minute Therefore T = 3.14 minutes. Therefore our model displacement, velocity and acceleration functions will be Displacement, y(t) = meters Velocity v(t) = 240 meters/minute Acceleration a(t) = mete rs/minute2 I have graphed the three functions for visual analysis as below. cosine displ paasenger.bmp Graph : Displacement graph for passenger elevator cosine velocity passenger.bmp Graph : Velocity graph for passenger elevator cosine acceleration passenger.bmp Graph : Acceleration graph for passenger elevator Form the above graphs we can see that with slight modifications of the model cosine function, it meets all the requirements of the high speed passenger elevator. So we can modify the cosine function so that the same can be adapted to any other similar application.

Standing before the huge plate-glass window in his Tokyo skyrise, Numataka took a long pull on his cigar and smiled to himself. He could scarcely believe his good fortune. He had spoken to the American again, and if all was going according to the timetable, Ensei Tankado had been eliminated by now, and his copy of the pass-key had been confiscated. We will write a custom essay sample on Digital Fortress Chapter 18 or any similar topic only for you Order Now It was ironic, Numataka thought, that he himself would end up with Ensei Tankado’s pass-key. Tokugen Numataka had met Tankado once many years ago. The young programmer had come to Numatech Corp. fresh out of college, searching for a job. Numataka had denied him. There was no question that Tankado was brilliant, but at the time there were other considerations. Although Japan was changing, Numataka had been trained in the old school; he lived by the code of menboko-honor and face. Imperfection was not to be tolerated. If he hired a cripple, he would bring shame on his company. He had disposed of Tankado’s resume without a glance. Numataka checked his watch again. The American, North Dakota, should have called by now. Numataka felt a tinge of nervousness. He hoped nothing was wrong. If the pass-keys were as good as promised, they would unlock the most sought-after product of the computer age-a totally invulnerable digital encryption algorithm.

Art for Heart`s Sake Interpretation Essay Example For Students

Art for Heart`s Sake Interpretation Essay The text under interpretation is a short story Art For Heart`s Sake by Reuben Garrett Lucius Rube Goldberg (July 4, 1883 – December 7, 1970), who was an American cartoonist, sculptor, author, engineer, and inventor. He is best known for a series of popular cartoons depicting complicated gadgets that perform simple tasks in indirect, convoluted ways. Goldberg was a founding member and the first president of the National Cartoonists Society, and he is the namesake of the Reuben Award, which the organization awards to the Cartoonist of the Year. Goldberg produced several series of cartoons all of which were highly popular. Among his best works are Is There a Doctor in the House? , Rube Goldberg`s Guide to Europe and I Made My Bed. The given extract introduces the readers to a story of a wealthy man called Collins Ellsworth who is treated for a disorder which causes irresistible desire of buying things, more commonly referred to as compulsive shopping or oniomania. The man`s obsessive condition leads him to unfortunate results and health problems. Knowing this, Mr Caswell, his doctor, suggests trying some art therapy. This therapy seems to be effective at first, and Caswell`s client even evinces interest to painting and the general drift of affairs in art galleries. subsequently Ellsworth executes a nonsensical unskillful work, which, to everybody`s astonishment, he later exhibits at the Lathrop Gallery. That picture gets the 1st prize of the Exhibition. The story ends with a revelation of the method that helped the old man win the prize. From the point of view of its composition, the story may be divided into four parts. The first part is an introduction starting with a dialogue between the old man and the male nurse. Which annoys the latter very much as the patient is a very disagreeable man, who refuses to follow doctor`s orders. Here we get acquainted with Ellsworth with his inherent disrespect for the people around him. Whether it is a male nurse or a doctor, who are with him in order to help, the businessman pulls no punches. It was not the first outburst of Ellsworth. So, instead of trying to demand an apology, the doctor suggests a new way of getting rid of old man`s problems. That`s where the 2nd part of the story starts. In this part we get to know that doctor considers busying his patient with art to be a way out. The idea of Caswell is to bring a young student Frank Swain to the patient. When Swain arrives to Ellsworth`s house, he starts the therapy, suggesting that the man should try to paint a vase. The old grump starts unwillingly. The first attempts do not meet success, but the practice leads to progress as the vase on the painting gradually develops resemblance to the one on the mantelpiece. Ellsworth asks Swain for more hours and seems to forget about his obsession. He becomes curious about what`s going on in art galleries. Some idea arises in his head. The third part of the extract is connected with the events in the Lathrop Gallery. There was an exhibition in it, which as a lifetime dream of the mature artists. And the newly-made artist Ellsworth aimed at showing his amateurish awkward painting there. The male nurse, Koppel, is sure that if it happens, the old man will become a laughing stock. But the doctor orders him to forbear from interfering in Ellsworth`s business not to ruin their achievements. The painting is accepted, but luckily for the worried fellows, it hangs in a corner where people can barely see it. This part also tells us about the events that took place two days before the closing of an exhibition. Swain, Koppel and the doctor witness a strange follow-up to the story. the old man receives a letter which surprises the people even more: the First Prize of the Lathrop Exhibition has been awarded to Ellsworth`s painting Trees Dressed in White. Euopean Art In The Wake Of World War 1 EssayHe would dwell on the rich variety of colour in a bowl of fruit, he proudly displayed the variegated smears of paint on his heavy silk dressing gown. He would not allow his valet to send it to the cleaner`s. he wanted to show the doctor how hard he`d been working). As Ellsworth gets acquainted with the world of the Museums and Galleries he`s being caught by its charming mysteries. The revolution of the seasons is portrayed with the wonderful metaphor: the spring sun cloaks the fields and gardens with colour. The old man`s idea, as he reveals in his startling announcement, is taking part in the exhibition. In order to do that he creates an ugly picture, which imperfection is described with the epithet god-awful smudge. That exhibition is a lifetime dream of the mature artists, so old man`s participation in it was shocking and out of place. Trees Dressed in white was not just bad. As the simile from the text imparts, it is like a salad dressing thrown violently up against the side of a house. The male nurse wants to stop Ellsworth, not to let him become a laughing stock, but the doctor insists on letting him finish, as they`ve got too far to lose everything. Luckily, the place where the picture hangs is inconspicuous. The metaphor a raucous splash on the wall reminds us about picture`s ugliness. It`s all is followed up by the ironies, which retell that the masterpiece was noticed by the people and as some guys stopped next to the Ellsworth`s strange anomaly, Swain fled in terror. When the letter from the Gallery arrives, Ellsworth requests somebody to read it, as his eyes, ironically, are tired from painting. The news is announced: the Gallery gives Ellsworth the first prize. The reaction of the characters, excluding the old man is quite predictable. While Koppel and Swain, overwhelmed by surprise, try to regain their ability to speak, the doctor congratulates the old grump, which is not easy, or, as the epithet says, is a supreme effort. In the end the reader gets to know that there was no miracle in Ellsworth`s win, that the old man owns a Gallery now. His last remark (Art`s nothing †¦ I bought the Lathrop Gallery last month) crowns the story, proving the point that nothing has changed in him.

Authorization Definition - How Federal Agencies are Born

Authorization Definition - How Federal Agencies are Born Did you ever wonder how a federal program or agency came into being? Or why they theres a battle every year over whether they should receive taxpayer money for their operations? The answer is in the federal authorization process. An authorization is defined as a piece of  legislation that establishes or continues one or  more federal agencies or programs, according to the government. An authorization bill that become law either creates a new agency or program and then allows for it to be funded by taxpayer money. An authorization bill typically sets how much money those agencies and programs get, and how they should spend the money.   Authorization bills can create both permanent and temporary programs. Examples of permanent programs are Social Security and Medicare, which are often referred to as  entitlement programs.  Other programs that are not statutorily provided for on a permanent basis are funded annually or every few years as part of the appropriations process. So the creation of federal programs and agencies happens through the authorization process. And the existence of those programs and agencies is perpetuated through the appropriations process. Heres a closer look at the authorization process and the appropriation process.   Authorization Definition   Congress and the president establish programs through the authorization process. Congressional committees with jurisdiction over specific subject areas write the legislation. The term â€Å"authorization† is used because this type of legislation authorizes the expenditure of funds from the federal budget. An authorization may specify how much money should be spent on a program, but it does not actually set aside the money. The allocation of taxpayer money happens during the appropriations process. Many programs are authorized for a specific amount of time. The committees are supposed to review the programs before their expiration to determine how well they are working and whether they should continue to receive funding. Congress has, on occasion, created programs without funding them. In one of the most high-profile examples, the  Ã¢â‚¬Å"No Child Left Behind† education bill  passed during the George W. Bush administration was an authorization bill that established a number of programs to improve the nation’s schools. It did not, however, say the federal  government  would  definitely spend money on the programs. An authorization bill is rather like a necessary hunting license for an appropriation rather than a guarantee, writes  Auburn University political scientist Paul Johnson.  No appropriation can be made for an unauthorized program, but even an authorized program may still die or be unable to perform all its assigned functions for lack of a sufficiently large appropriation of funds. Appropriations Definition In appropriations bills, Congress and the president state the amount of money that will be spent on federal programs during the next fiscal year.   In general, the appropriations process addresses the discretionary portion of the budget – spending ranging from national defense to food safety to education to federal employee salaries, but excludes mandatory spending, such as Medicare and Social Security, which is spent automatically according to formulas, says the Committee for a Responsible Federal Budget. There are 12 appropriations subcommittees in each house of Congress. They are divided among broad subject areas and each writes an annual appropriations measure. The 12 appropriations subcommittees in the House and Senate are: Agriculture, Rural Development, Food and Drug Administration, and Related AgenciesCommerce, Justice, Science, and Related AgenciesDefenseEnergy and Water DevelopmentFinancial Services and General GovernmentHomeland SecurityInterior, Environment, and Related AgenciesLabor, Health and Human Services, Education, and Related AgenciesLegislative BranchMilitary Construction, Veterans Affairs, and Related AgenciesState, Foreign Operations, and Related ProgramsTransportation, Housing and Urban Development, and Related Agencies Sometimes programs dont get the necessary funding during the appropriations process even though theyve been authorized.  In perhaps the most glaring example, critics of the â€Å"No Child Left Behind† education law  say that while Congress and the Bush administration created the program in the authorization process, they never adequately sought to fund them through the appropriations process.   It is possible for Congress and the president to authorize a program but not to follow through with funding for it. Problems With the Authorization and Appropriations System There are a couple of problems with the authorization and appropriations  process. First, Congress has failed to review and reauthorize many programs. But  it also has not let those programs expire. The House and Senate simply waive their rules and set aside money for the programs anyway. Second, the difference between authorizations and appropriations confuses most voters. Most people assume that if a program is created by the federal government  it is also funded. Thats wrong.   [This article was updated in July 2016 by U.S. Politics Expert Tom Murse.]

The Best ACT Reading Practice Tests and Questions

The Best ACT Reading Practice Tests and Questions SAT / ACT Prep Online Guides and Tips Doing well on ACT Reading requires a fair amount of practice, especially if you’re not used to the format and timing of the test. In order to get the most out of your study time, you need to be using the highest quality practice materials available to you. In this article, I’ll go through some of the best resources for ACT Reading practice tests and tell you why you should use them! High Quality Practice Tests Are Important for ACT Reading! Many students don’t realize the importance of making sure the practice materials they’re using are super high quality.If you practice with shoddy materials, you’re going to get shoddy results - that’s just life.This holds as true for ACT Reading as it does for anything else. Some test prep companies put out books with their own practice questions that are not from the official ACT. DON’T RELY JUST ON THESE QUESTIONS! Some of them are ok, but if you want to get the most out of your practice sessions, you should start with official questions.If you’re not practicing for ACT Reading with real ACT materials, you’re not going to be learning the exact skills you need to beat the test. Since the ACT is a standardized test, the more questions you practice that follow the real ACT standardization model, the easier it’s going to be to understand the answers and feel confident on the real test.On reading, it’s important not only that you’re practicing with real ACT questions but also that you’re reading real passages that were included on the ACT at one time or another. These passages will be calibrated for difficulty level, length, and reading time in ways that only ACT, Inc. fully understands (and that can't necessarily be faithfully replicated by test prep companies). There are two components to each question on the reading section: the question itself and the passage it references.If either one of these components on a practice test is different from what you will actually see on the ACT, you could have a problem with discrepancies between your expected results and your actual results when confronted with the real test. Here’s a list of different practice test resources in different media that you should use for reliable ACT Reading prep. Free Official ACT Reading Printable Tests ACT Practice Test 2015-2016 (Form 72CPRE)ACT Practice Test 2014-15 (Form 67C)ACT Practice Test 2011-12 (Form 64E)ACT Practice Test 2008-09 (Form 61C)ACT Practice Test 2005-06 (Form 59F) These free PDFs of past ACTs are your best bet to get the most accurate score predictions and most true-to-life practice test experiences.It’s absolutely critical for ACT practice that you use real questions put out by ACT, Inc. first and foremost, and try to avoid questions devised by test prep companies.The only way you’ll be prepared for the reading questions on the test is if you are used to answering questions with the same phrasing and structure.You want to get used to the types of passages you’ll see on the real ACT reading and what kinds of questions are asked about them. You should also remember to time yourself accurately whenever you take a practice test!That means giving yourself exactly 35 minutes for the reading section.Otherwise, you’re not going to get an accurate picture of your scores in a real test environment.For PDF tests, you should print them out and make a separate answer sheet for yourself to write down the answer to each question so that you can replicate testing conditions as closely as possible. If you really want to replicate testing conditions accurately, you should take it in a school classroom. But only if you have permission. Then again, if you break into your school to take an ACT practice test you might become famous as the world's nerdiest criminal, so there are pluses and minuses. Online ACT Reading Resources ACT Online Program This costs $25 and will give you two extra practice tests.Don’t use it for the actual practice lessons because they’re not very helpful; it’s just a way for you to get access to some extra official practice questions. PrepScholar Test Prep Platform This is our test prep program which tailors questions to your studying needs.It includes up to 5 official ACTs as a part of your customized study plan. If you click on the link above you cansign up for a 5 day free trial to see how it works! Just to let you know, our questions are technically not official, though our test experts have worked very hard to get them as close as possible to the format of the real test. PrepScholar also costs money after the free trial, but you'll get your money back if your scores don't improve. Print Resources The Real ACT 3rd Edition or "Red Book" This book costs $20.It’s your best bet for realistic practice tests because it has questions from, obviously, the Real ACT.There are 7 full-length practice tests in this book, and 5 of them are actual previously administered ACTs.Try to lean towards using the most recent practice tests that are included in the book.There is a general consensus that the ACT has gotten harder over the years, so your scores might be skewed high as compared to what you should expect on the real test if you take more out of date practice tests. While this book is great for practice materials, it’s not as helpful in terms of test taking strategies, which is why you should use it in conjunction with my next recommendation, the Black Book, so you get the best of both worlds. ACT Black Book This book costs $20 as well.It doesn’t have practice questions of its own, but you can use it alongside the Real ACT 3rd Edition or â€Å"Red Book† because it refers to questions in the Real ACT 3rd Edition as examples. You can't use the Black Book in isolation. The Black Book is helpful because it provides a no-nonsense approach to the test that works across subject areas. It’s dedicated to teaching you how the test works and how you can beat it.It also gives you in-depth descriptions of the reasons behind answer choices, which are lacking in the Red Book. The Black Book can be wordy and does require a high level of engagement from the reader, so make sure you’re prepared to read closely and pay attention. You’re going to get out of it what you put in! The Complete Guide to ACT Readingby Erica Meltzer This book costs $30, so it’s a little pricier.It provides realistic passages and questions for you to study from so that you’ll be prepared for anything the test throws at you.It also identifies the skills you’ll need to do well very effectively, even though these skills are more difficult to nail down in reading than in, say, math. You can read our complete review of this book here. Summary In your studying for ACT Reading, always remember to use the highest quality practice materials available to you.This means official questions from ACT, Inc., not questions manufactured by test prep companies that might be easier than real ACT questions or an inaccurate reflection of what’s covered on the test. You can use one of the free PDFs of past ACTs, reliable online resources, or high quality review books to get the best practice materials.

New Organizational Forms - Innovativeness To Attain Competitive Essay

New Organizational Forms - Innovativeness To Attain Competitive Advantage - Essay Example Clegg, Kornberger, and Pitsis noted that more and more companies are embracing new organizational forms. The new forms, as Clegg et al. explain, are readily replacing reliance on market oriented governance arrangements and embracing stronger centralization and joint decision making approaches. Organizations are rapidly changing their operations towards larger customer oriented units and relying on a rich set of integration mechanisms within these entities. This largely results in different forms of internal hybrids that enhance lateral sharing of individual and organization knowledge, aimed at achieving economies of scale and scope. Similarly, as Green elaborates, companies through the HR have to strategize on setting a single set of metrics to gauge all the manpower, in ensuring effective integration of these business units as businesses reshape into a larger customer oriented units according to the global business environment. Weber’s bureaucracy theory presents the best sce nario of the new organizational forms. Clegg et al. (2012) note that Weber’s bureaucracy theory requires that jurisdictional areas be well specified with activities that are well distributed as personal official duties, whereas the traditional approach requires activities to be delegated by the leader and can be changed at any particular time. In addition, Weber noted that officials in the organization have to be chosen based on technical qualifications, appointed and not elected, and well compensated to motivate them to perform.

ACCOUNTING ASSIGNMENT Example | Topics and Well Written Essays - 2500 words

ACCOUNTING - Assignment Example The following suggestions are discussed in depth in this report. We are under budget on revenue and over budget on expenses. This means that we are under budget on the profit. We do not have a balance sheet and the accounts on our Profit & Loss report are general accounts at best. There is no record of what types of appointments the customers are requesting instead we know the quantity of them but not the quality of the appointments. We have a retail area that accounts for a small percentage of the revenue. We do not know how long customers are here for their appointments so instead we guess at it. We do not suffer from seasonality therefore we have a steady stream of clients coming in all year round. This opens up a great opportunity for us to track repeat customers as well as new customers. We have the privilege of having great name recognition within the community which helps us to get repeat business. We also do not have any direct competition and this helps us to constantly keep a steady flow of customers coming through the doors. Our main weakness starts with our inability to track our clients and our personnel. We do not know what type of massage our customers want until they are in the room with one of our therapists. This makes it difficult to decide which types of massage to offer and not offer. It also makes it difficult to determine prices for each type of massage. We have the opportunity to cross sell our customers if we were to improve our methods of reporting information. Our retail sales could increase if we were to focus in on our customers’ needs by keeping better records of each one and what they request while they are here. We could also use this information for marketing any new services. We need to have a better grasp on the budget. Our numbers are way off and we need to get a better idea of what our projections should be. Our projections should be based off our prior year along with some growth

Taxation Law and Practice A Case Study Example | Topics and Well Written Essays - 2000 words

Taxation Law and Practice A - Case Study Example This is in order to avoid double taxation as Joe is still going to pay income tax on this amount as part of his income. The bonus payment of $5,000 shall not be considered for this particular period. This is because it was paid to Joe on 10 July 2014 .This particular date falls outside of the financial year 2013/14 that runs from 1July 2013 to 1 July 2014. In Section 8.1 of the ITAA97, the company is allowed to deduct any amounts from its assessable income if this amount was incurred in the gaining or the production of the assessable income. In this situation, the amount paid to Joe was for his skills as a labourer. This skill enabled the company to conduct its business and hence be able to make income from its activities. It is therefore right to assume that the amount the company paid to Joe should not be taxed and is therefore a deductible from the assessable income of the company. MM have to pay employee super. The Superrannuation Guarantee (Administration) Act 1992 governs the relationship between employees and their employers. It includes details about the employer’s liability in the making of the payments. It also states how the calculation of the super guarantee charge is done. Contributions should be paid by the 28th of the month that follows the end of the quarter1. Failure to do this will result in the payment of a superannuation charge by the employers. Joe is qualified to have this payment made for him on his behalf by the company. The requirements are that the employee should be over 18 years old and they should earn more than $450 before taxation in a calendar month. Super payments are normally calculated and made after every three months. The payment of a former employee of backdated payments means that the super payments that had accrued to that employee must also be paid. The employees that are excluded from this arrangement include those who earn less than $ 450 in a month. Employees who are

Physiology Of Sleep

Physiology Of Sleep Physiology Of Sleep Introduction Sleep is a state of reversible unconsciousness in which the brain is low responsive to external stimuli. We are functionally blind during sleep with no response to visual stimuli and a decreased threshold of response to auditory stimuli. Babies have been exposed to sound of up to 100 dB, which is above the legal limit for ear protection for employees, without waking up. In adults, the action is selective demonstrating continuing cortical function. For example, a sleeping mother is woken by her crying baby but not by other louder noises. Definition of sleep and sleeping Phases with specific EEG patterns and physiological changes. Natural sleep is separated into two distinctive states: non rapid eye movement (N.R.E.M) and rapid eye movement (REM) sleep. NREM sleep is then further seperated into 4 stages where stage 1 is the lightest and stage 4 the deepest level of sleep. REM sleep is divided into phasic and tonic phases. The two distinctive states follow a regular pattern called a sleep cycle which, in an adult, lasts about 1 and half hours and comprises a period of N.R.E.M sleep followed by REM sleep. The cycles may be separated by a period of wakefulness and are repeated 3–6 times each night and are typically displayed as an hypnogram (Fig. 1). The majority of deep (stage 4) NREM sleep occurs in the first and second cycles. As the night progresses, the proportion of REM sleep in a cycle increases and the NREM element is of lighter stage 2 sleep. Age has a major effect on the duration of sleep and the ratio of NREM/REM sleep. Neonates sleep 16–18 h. It is widely distributed throughout the day with REM sleep accounting for 50% of total sleep time (TST). This may be even greater in premature babies. By the age of 24 months, children should sleep 10 h per day, mainly at night with one or two naps during the daytime and REM sleep has declined to 20–25% of TST. Adults normally sleep 6–8 h per day with 15–20% REM sleep. With increasing age, TST changes little although sleep is more fragmented with more frequent and longer awakenings (decreased sleep efficiency) with less REM sleep and more light NREM sleep. Night-time sleep may be decreased if naps are taken during the day. Functions of sleep The functions of sleep are still poorly understood. However, the observation that sleep (or, at  least, an activity–inactivity cycle) is present in all species and has been preserved throughout evolution and that sleep deprivation leads to a drastic deterioration in cognitive  function and eventually to mental and physical morbidity proves its importance. It has been suggested that sleep might conserve energy by reducing core temperature slightly and lowering metabolic rate by 10% compared with quiet wakefulness. Sleep would prevent perpetual activity as a response to environmental stimuli leading to excessive energy consumption. However, sleep is a state of starvation and there is no evidence that sleep is important for tissue repair. Sleep has been implicated as an important factor in storage of long-term memory. Facts learned during the day are usually better remembered the next morning whereas facts learned shortly before going to sleep are often poorly recalled. Electrophysiological features of sleep The stages of sleep are characterised by typical patterns of electroencephalogram (EEG), electro-myogram (EMG) and electro oculogram (EOG) activity Wakefulness with open eyes is characterised by an EEG with dominant low amplitude, high frequency beta activity of  16–25 Hz. Muscle tone is normally high with high to moderate EMG activity. Stage 1 Sleep is usually initiated by a transition from wakefulness to a state of drowsiness with closed eyes and a shift from EEG beta activity to alpha activity of 8–12 Hz passing to Stage 1  NREM sleep with a mixed frequency EEG-pattern with low amplitude theta waves of 3–7 Hz accompanied by slow rolling eye movements. Involuntary muscle clonus occurs frequently,  resulting in jerky movement of the whole body (hypnic jerks) and EMG activity is moderate-to-low. This stage lasts typically only 5–10 min, during which time minor auditory stimuli will cause arousal. Stage 2 Stage 2 is characterised by short bursts of high frequency activity (12–15 Hz – sleep spindles) and K-complexes (large amplitude biphasic waves). Bodily movements continue and  the EMG activity is low-to-moderate. This stage is generally short (10–20 min) in the first 1–2 cycles but predominates in later cycles. It is the most abundant sleep stage in adults  accounting for up to 50% of TST. Stages 3 and 4 Deep NREM sleep stages 3 and 4, sometimes combined as slow wave sleep (SWS) are characterized by high amplitude low frequency delta waves (> 75 µV and 0.5–2 Hz) with stage  3 having between 20–50% and stage 4 more than 50% delta activity. EMG activity is low and eye movements are rare. Arousal through auditory stimuli from this stage of sleep is  difficult and, if awakened, the individual is often disorientated and slow to react. Return to sleep is easy and short arousals (< 30 sec) are rarely remembered. REM sleep NREM sleep is followed by REM sleep, the proportion increasing with each cycle. REM sleep is characterised by a fast mixed frequency low voltage EEG with saw-tooth waves and  rapid eye movements on the EOG. During the tonic phases of REM sleep, there is marked reduction of muscle tone and EMGactivity in skeletal muscles. The tonic phases of REM sleep are interrupted by short episodes of phasic REM sleep with increased EMG activity and limb twitches. The atonia of REM sleep affects all skeletal muscles, except the diaphragm and the upper airway muscles, and is associated with hyperpolarisation of the ÃŽ ±-motor neurones. The purpose of this may be to prevent the acting out of dreams. About 10% of the population have experienced sleep paralysis (i.e. wakening from sleep and finding that the atonia has  persisted into wakefulness). It can be frightening but is entirely harmless. Natural wakening usually occurs from REM sleep. Subjects woken from REM sleep are much more likely to rec all dream content than those awakened from NREM sleep. NREM dreams are generally vague and formless in contrast to REM dreams. Physiological changes during sleep Respiratory system During NREM sleep, there is a decrease in respiratory drive and a reduction in the muscle tone of the upper airway leading to a 25% decrease in minute volume and alveolar ventilation and a doubling of airway resistance accompanied by a small (0.5 kPa) increase in  PaCO2 and decrease in PaO2. Hypercarbic and hypoxic ventilator drives are reduced compared with wakefulness. The breathing pattern is regular except at the transition from wakefulness into sleep when brief central apnoeas are common. During REM sleep there is a further decrease in hypercarbic and, particularly, hypoxic ventilatory drives. The breathing pattern is irregular especially during phasic REM sleep. The loss of skeletal muscle tone in REM sleep affects the intercostal and other muscles which stabilise the chest wall during inspiration. In infants, this may be seen as paradoxical movement of the rib cage and abdomen. In adults, there may be maldistribution of ventilation and impaired ventilation–perfusion matching with consequent arterial hypoxaemia. In normal subjects, this is unimportant but it may be very important in patients with chronic lung disease or abnormalities of the thoracic (e.g. kyphoscoliosis). The great majority of patients with impaired respiratory function will be at their worst during REM sleep. Cardiovascular system Blood pressure decreases during NREM and tonic REM sleep but may increase above waking values during phasic REM sleep. Cardiac output is generally decreased during all sleep  phases. Systemic vascular resistance (SVR) and the heart rate are both reduced during NREM and tonic REM sleep and increased during phasic REM sleep. Central nervous system Cerebral blood flow (CBF) increases by 50–100% above the level of resting wakefulness during tonic REM sleep and is even greater during phasic REM sleep. Cerebral metabolic rate, oxygen consumption and neuronal discharge rate are reduced during NREM sleep but increased above resting values during REM sleep. The autonomic nervous system shows a general decrease in sympathetic tone and an increase in parasympathetic tone,  except in phasic REM sleep. Renal system The glomerular filtration speed and filtration fraction are reduced and ADH secretion is increased resulting in a less volume concentrated urine. Endocrine system The secretion of several hormones is directly linked to the sleep/wake cycle. Melatonin is released from the pineal gland under the control of the supra-chiasmatic nuclei (SCN) in a 4–5h pulse, usually beginning at the onset of darkness (~9 pm). The pulse is inhibited or delayed by exposure to bright light in the evening. It is best regarded as being permissive of sleep (‘opening the gate to sleep’) rather than as an hypnotic, as it is possible to maintain wakefulness during this period. Growth hormone is mostly secreted during the first episode of SWS, particularly  during puberty. Prolactin concentrations also increase shortly after sleep onset and decrease with wakefulness. Sleep phase delay delays secretion of both of these hormones. The secretion of cortisol decreases with the onset of sleep and reaches a trough in the early hours of the morning and a peak just after waking. Temperature control In contrast to anaesthesia, thermoregulation is maintained during sleep. However, the shivering threshold is decreased and body core temperature decreases by about 0.5 °C in humans and 2 °C  in hibernating mammals. Body temperature is linked to the circadian rhythm and reaches its nadir at about 3 am. Thermoregulation is quite good in human infants compared with  other species. Control of sleep Sleep follows a circadian (~1 day) cycle, the periodicity of which is regulated by an independent genetically determined ‘intrinsic clock’ which is entrained to a 24 h cycle by external cues (Zeitgebers) such as light, darkness, clock time, working patterns and meal times. When a human being is deprived of all external time clues and is exposed to constant levels of illumination (‘free running’), the wake/sleep cycle typically lengthens to about 24.5 h. Subjects who are born blind without any appreciation of light generally free run while those blinded in later lifeor who retain some perception of light remain entrained. All living organisms, including plants and fungi, have been found to have clock genes and to show an inactivity/activity cycle. In mammals, control of the intrinsic clock is located in the SCN on either side of the third ventricle, just above the optical chiasm. In animal experiments, its destruction leads to a change from the normal sleep cycle into several shorter sleep/activity periods during the day. As noted above, melatonin secretion is  prompted by the SCN just before the usual time of sleep onset. A mismatch of this pattern with sleeping time, as occurs in shift workers and after trans-meridian flights, leads to sleep disturbance (‘jet lag’) as the subject is trying to sleep during their circadian day. Light therapy can be helpful in re-setting the circadian clock and the interested reader is referred to the bibliography. The propensity to fall asleep varies throughout the day and depends upon both circadian factors (process C) and time since the last sleep period (process S). The longer the time since the  last sleep period, the greater will be process S. However, its propensity will be modulated by process C. The circadian pressure to sleep is greatest at ~2 am with a secondary peak at ~2 pm. It is least at ~6 am and ~6 pm. If a subject elects to stay awake throughout the night, they will feel most sleepy in the small hours of the morning but will get a ‘second wind’ as morning approaches and the circadian pressure to sleep declines. If wakefulness is maintained, a second period of sleepiness and relative alertness will follow in early afternoon and early evening, respectively. Some of the 8-h sleep debt will be recovered that night but process C will ensure that awakening will occur at or shortly after the normal waking time. Sleep is normally an actively initiated and not a passive process. Unless a subject is sleep deprived, successful initiation of sleep depends both upon the phase of the circadian clock and  external factors (recumbent position, darkness, reducing sensory input). Over the years, considerable effort has been focused on a search for: (i) a ‘sleep centre’, a nucleus or region in the brain where stimulation or ablation would lead to sleep; and (ii) a hormone or transmitter which would reliably induce sleep. Neither have been found because the mechanisms resulting in sleep are complex and diffuse. During wakefulness, the CNS is dominated by activity of the ascending reticular activating system (RAS) in the brain stem. This formation receives sensory input from all peripheral sensors and projects to the thalamus and the cortex. Its main neurotransmitters are acetylcholine, noradrenaline, dopamine and histamine which explains the sedative effect of antagonists to these  substances. A decrease in its activity permits sleep to be initiated by suppressing incoming external stimuli. The induction of SWS is associated with the secretion of ÃŽ ³-aminobutyric acid (GABA) from basal forebrain neurones. Therefore, it is not surprising that benzodiazepines and barbiturates, which act through stimulation of GABA receptors in the CNS, induce sleep or anaesthesia. Cholinergic mechanisms initiate REM sleep through stimulation of pontine neurones in the  lateral portion of the pontine tegmentum and the nucleus reticularis pontis oralis. In animal experiments, injection of carbachol (acetylcholine agonist) induces instantaneous REM sleep. Recently, orexins (hypocretin) have been isolated in the hypothalamus and appear to be important in the control of REM sleep and appetite. CSF concentrations of orexins have been found to be very low in patients with narcolepsy. Influence of surgery and anaesthesia on sleep Anaesthesia and surgery can have a profound effect upon sleep. On the first night after surgery, sleep architecture is severely disrupted with little or no SWS and REM sleep. The  light Stage 2 sleep is fragmented with frequent awakenings. The degree of disruption appears to be related to the severity of the surgical insult. The mechanism is unclear but it is probably due to a combination of the surgical stress and the effects of opioid analgesics. Recovery of lost SWS and REM sleep occurs on postoperative nights 2–5, being later after major surgery. This coincides with the nadir of postoperative pulmonary function and several  studies have demonstrated marked hypoxaemia associated with the rebound of REM sleep. It was a logical step to attribute postoperative myocardial ischaemia, myocardial infarction, pulmonary embolism and cerebral disorder (delirium and cognitive impairment) to nocturnal hypoxaemia. However, a number of studies have failed to confirm these presumed associations,  although this does not exclude the possibility that the hypoxaemia may be important in some individuals.

Amazon :: science

Amazon The Amazon River is the second longest river in world. The headwaters begin high in the soaring Andes Mountains and stretches 6,400 km across the South American continent to the Atlantic Ocean. It discharges between 34 to 121 million liters of water per second, and depositing an average of 3 million tons of sediments near its mouth. The outpouring of water and residue is so vast that the salt content and the color of the Atlantic Ocean are altered for a distance of about 320km from the mouth of the river. Also, unlike many other rivers it ¡Ã‚ ¯s wide and straight from the headwaters to the mouth. During a new or full moon, a wave front from the ocean sweeps 650km upstream at speeds of 65km/h and this causes waves as high as 5m. Because of its vastness, annual floods, and navigability, the Amazon River is often called the Ocean River. The Amazon River is the largest and wettest tropical plain on Earth with heavy rains. Europeans were not the original keepers of this vast rainforest. The Amazonians are trapped between the old and new customs, and since they have traditions, their technology isn ¡Ã‚ ¯t as modern as the rest of the worlds ¡Ã‚ ¯. They live on the richest land with a wide variety of flora and fauna. With such great resources, including the river as transportation, almost anybody would want to seize the land and gain profits easily. The Amazonians have little power to defend themselves with spears against their guns. Unfortunately, the outside world has brought them diseases that are incurable with their own medicine. They cannot exist in the way they were before, but they know the Amazon better than any of us. If the rich businessmen listened to them instead of stealing from them, they might be able to improve the usage of the Amazon. All the tributaries merge into the Amazon River, but not all have an identical color. White-water rivers, the ice and snow from the Andes Mountains washes off soil nutrients from the rocks, allowing the water to have a dirty yellowish color. Clear-water rivers are azure-green in color; they barely contain any sediment. These rivers arise from the highlands that are created by hard rock that doesn ¡Ã‚ ¯t easily erode. Dark black-water river of the Rio Negro washes over old rocks, which are rich in minerals. The name  ¡Ã‚ °Amazon ¡Ã‚ ± just isn ¡Ã‚ ¯t any old name.

Milgram Behavioural Study of Obedience Essay

The method used by Milgram was the laboratory experiment. The main advantage that Milgram had with this method was the amount of control he had over the situation. He controlled what the participants saw, heard and experienced and was able to manipulate their behaviour through what they were exposed to. This method also allowed accurate measurement of variables and the clear standardised procedures meant that replication was possible. The disadvantages of this method include low ecological validity and the influence of demand characteristics on the participants and it could be argued that they were behaving in the way that they thought was expected of them rather than producing natural behaviour. Milgram has also been heavily criticised regarding the ethics of this study (see below) . Was the sample representative? Milgram’s sample was a self-selected sample of 40 males obtained through advertising. This could be regarded as being a biased sample as they were all male American citizens. They were also volunteers and the majority of the population is unlikely to volunteer to take part in research and those who do may be atypical of the target population in some way. Hence there may be problems generalising from these results. What type of data was collected? The data collected was quantitative in that it involved measuring participants’ obedience level, numerically, in terms of how far up the voltage scale they were prepared to go. This type of data has the advantage of being easy to compare and statistically analyse. However, Milgram included no qualitative descriptions of why the participants obeyed or how they felt during the experiment although there are a few brief descriptions of participants’ behaviour during the experiment. Does this study have high or low Ecological Validity? As with all laboratory experiments there are problems with Milgram’s study regarding its ecological validity. It involved an extremely unusual task carried out under very artificial conditions and as such, is likely to have produced very unnatural behaviour from the participants. This has implications for the extent to which we can generalise from these results to real life situations and it can be argued that the study tells us nothing about obedience in everyday life but simply shows us how obedient these people were, in this environment, performing this task. Was the study ethical? Milgram’s study was probably one of the most unethical pieces of psychological research ever conducted. It can be criticised in terms of almost all the British Psychological Society Ethical Guidelines including informed consent, deception, right to withdraw and protection from harm. However, in Milgram’s defence, we can argue that he did not expect the participants to obey to the extent that they did or to find the task so stressful. He also conducted a thorough debriefing and follow-up monitoring of his participants. A survey conducted one year later revealed that 84% of the participants were glad to have taken part in the study and psychiatric examinations of them showed that none had suffered long term harm. What does this study tell us about Individual and Situational Explanations of behaviour? The individual explanation for the behaviour of the participants would be that it was something about them as people that caused them to obey, but a more realistic explanation is that the situation they were in influenced them and caused them to behave in the way that they did. Some of the aspects of the situation that may have influenced their behaviour include the formality of the location, the behaviour of the experimenter and the fact that it was an experiment for which they had volunteered and been paid. How useful is this research and to what extent can it be applied to everyday life? As stated previously, the stimulus for this study was the Holocaust and this study has contributed significantly to the discussions regarding the behaviour of the Germans at this time. In particular, it provides strong evidence against the ‘Germans are different’ hypothesis. It also gives a valuable insight into the power of situations and of authority. The results suggest that we have a natural tendency to obey authority figures even when we feel that what we are being asked to do is morally wrong. However, the applications are restricted by the methodological limitations such as low ecological validity and an unrepresentative sample.

5 Questions to Consider When Writing for Children

5 Questions to Consider When Writing for Children 5 Questions to Consider When Writing for Children 5 Questions to Consider When Writing for Children By Mark Nichol â€Å"I want to write a book for children† gets you about as far as saying, â€Å"I want to write fiction† or â€Å"I want to write nonfiction.† It’s a start, but only that. There are many forms and genres and age groups to consider, and though you can certainly move fluidly among them, what you’re going to write right now needs more focus. As you develop your ideas for a children’s book, be sure to answer these questions: 1. What do you want to write about? Is your book going to be autobiographical or semiautobiographical? Is it about a natural phenomenon, or a historical event, or a social issue? It is about a cultural or artistic topic? Write a sentence no longer than any of the ones in this paragraph that summarizes what the book is about. Or step back even further and try a tagline like the snappy phrase on a movie poster or a book’s back cover that encapsulates the theme. (The tagline for one story I’ve been working on is simply â€Å"Believe.† Another theme is â€Å"Friends don’t hesitate.†) 2. What form will the story take? Is the book nonfiction, explaining a scientific concept or exploring an issue from the past or present? Or is it going to be a fictional account of a scientific discovery or a story that takes place during a significant historical event or cultural movement? Either form may serve the subject matter well, but you must decide which one this project will take before you develop the narrative. 3. What’s the target demographic? â€Å"Children’s books† is a huge category. Are you writing for beginning readers, elementary school students, preteens, or adolescents? Will children of one gender or another be more likely to read your book? Is it directed toward a certain ethnic group (but written in such a way that others don’t feel excluded)? Research reading levels and match your book’s vocabulary to the intended age range. Decide who the ideal reader is, and check your work frequently to make sure you’re focusing on that child. If you repeatedly veer off, don’t try to force yourself to get back on target when it’s obviously not the right fit. Change the target. 4. What’s my word count? For very young children, picture books (generally 28 pages in a 32-page book with up to a few sentences on each page) are the norm. You should be able to tell your story or account in as little as a few dozen words for preschoolers to up to several hundred for seven- or eight-year-olds. Chapter books novels for readers this age or slightly older, might have up to a thousand words or so. Preteens can handle up to 40,000 words or so, and young teenagers about twice that; books for older adolescents, like those for adults, are often 100,000 words or more. 5. How do I want readers to feel? Basically, comfort young readers, and challenge older ones. For preadolescents of any age, nonfiction should not frighten children with stark facts about environmental crisis, for example, and fiction should not expose them to unhappy or uncomfortable circumstances. The violence and turmoil of the kind found in fairy tales and myths is acceptable, but real-life mayhem is off limits. Teenagers, on the other hand, are coming to grips with reality and can more or less handle more adult-themed materials as long as it’s not explicit or bleak. Psychological issues, familial and societal friction, and other mature themes are appropriate when handled evenhandedly. Even books for adolescents, however, should have upbeat conclusions. (Comeuppance for villains or reprobates is fine, but sympathetic characters, while they should be given obstacles and ordeals to overcome and can experience physical and psychological pain, should emerge from the story intact.)

SLP internal analysis and SWOT Analysis

SLP internal analysis and SWOT Analysis Introduction Resource Based View is a modern day management tool that is used in crafting company’s strategy using the available resources and distinctive capabilities. One of the ways of achieving this is the use of Economic Values Added (EVA) or the Economic Rent (Connely, 2010). The EVA is gotten by subtracting the firm’s Net Operating Profit After tax (NOPAT) from the multiplication of the firm’s cost of capital by the firm’s capital i.e. NOPAT – (CAPITAL * COST OF CAPITAL).Advertising We will write a custom coursework sample on SLP internal analysis and SWOT Analysis specifically for you for only $16.05 $11/page Learn More A firm’s competitive advantage is therefore determined by its ability to use the available resources and utilize the core competencies to achieve targeted objectives (Barney, 1991). This paper discusses the various resources and competencies that an organizational can use to achieve competitiv e advantage over other firms. Sources Ensuing are two sources that offer information about these resources and competencies that provide a foundation for the formulation of a firm’s strategy. https://www.marketingteacher.com/swots these internal factors are resources such as human capital, patents, skills, goodwill and physical resources such as equipment and buildings. The disadvantage of this source is that the firm only uses internal environment to formulate the strategy ignoring the external environment which presents conditions that a business operates in. https://fba.aiub.edu/Files/Uploads/MGT110043.pdf. In his book, Henry presents the resource based view as a management tool for strategy formulation. Distinctive capabilities are useful in a firm’s competitiveness since the competitors are unable to duplicate them. The limitations of this source are that it looks at the firm which is established and has heavily invested in research and developments thus have acqu ired competencies in the specific operation area. Small firms are therefore not able to use these types of resources. Resources Resources are the inputs that a company uses in all the functional areas of its operations to produce the desired output and thus achieve the set target (Comeford Callaghan, 2011). Financial resources ensure that a firm has adequate amount of liquid cash to carry out the operations as well as finance the expected investments. This keeps the firm’s value high since its equity is not composed of large amounts of debt.Advertising Looking for coursework on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Human resources are other important organizations physical resources that ensure that the firm’s operations are of high quality. A workforce that is highly competent will make sure that the firm’s products are of high quality and also the firm employs efficient producti on methods resulting in low production costs. Technical resources are intangible resources which enhance a firm’s products quality. Advanced technical knowledge in the production process ensures that the firm’s products are preferred over the competitors since they are of superior quality (Barney, 1991). This therefore acts as an important resource that will form a basis of customer loyalty hence boosting a firm’s profitability. Intellectual resources are resources that a firm has acquired through research and development. These include patents and copyrights. Patents ensure that a firm possesses the exclusive right over certain means of production (Barney, 1991). A firm considers patents as important assets since it is able to employ unique production methods to achieve better results than the competitors. Goodwill is resources which a firm bears that make provide a competitive advantage over others. It may be in form of location, first mover advantage or custo mer loyalty. Goodwill usually puts a firm at a better state than the competitors and usually results in customer loyalty. It is therefore important in formulation of the firm’s strategy since it will ensure that firm strategic location and actions that will make it favorable over the competitors. A firm’s reputation ensures that it bears goodwill and this acts to foster the customer loyalty on the products. Architecture is the ability of a firm to bear different structures and networks that ensure it is well positioned to take on the competition provided by the other market players. Innovation gives a firm the ability to come with new products that are more appealing to the ever changing consumer tastes and preferences. A firm that is able to come up with new products will always enjoy a competitive advantage since its products will address the consumers presents tastes and preference.Advertising We will write a custom coursework sample on SLP internal analysis and SWOT Analysis specifically for you for only $16.05 $11/page Learn More Conclusion The Resource Based View is therefore and important management tool that is used to formulate a company’s strategy using the internal environment analysis. An internal environment will always provide the controllable parameter that an organization can manipulate to achieve its set targets and objective. References Barney, J. B. (1991).

Frankenstein Essay Example | Topics and Well Written Essays - 500 words - 5

Frankenstein - Essay Example The ability to do something, does not guarantee that one should simply do it. Some experiments should not be carried out just because of availability of the necessary skills and equipment. Scientists ought to pause, and think about implications of what they want to conduct. In addition, they should distinguish between the moral and immoral. Conducting an immoral medical practice causes definite harm to society. Therefore, availability of technology to perform an act should not be the only element that dictates scientific activities. In relation to Frankenstein, he had all the necessary materials required to create the monster. He continued to give it life without thinking of the implications the creature would have on society. Consequently, many people from Frankenstein family lost their lives. Others were blamed for the injustice, instead of Frankenstein or the monster, thus causing more pain to the society. Given that science can be seen as a body of knowledge that can give man God-like abilities, medical practitioners should employ ethics in the different experiments that they conduct. One of the medical ethics relates to ensuring that the doctor works in the best interest of the patient. The practitioner ought to protect the patient from any harm, and promote their comfort. However, Frankenstein did not uphold such care to the creature he created. The creature had life; it walked, communicated, and even demanded for its rights, just like a normal human being (Shelley, 2010). Given these traits, the creature needed a mate for it to lead a comfortable life. On the contrary, Frankenstein did not think about the happiness of the monster and its existence on earth. It did not have any companion, and creation dictates a male and a female for life to be complete. Failure to incorporate such ideas in his experiment devastated him, leading to misery. Consequently, medical practitioners must a lways weigh their actions, and

Essay about the provided story Example | Topics and Well Written Essays - 2500 words

About the provided story - Essay Example All these family excursions were great, but I had always wanted to visit California – Hollywood, Rodeo Drive, San Francisco†¦Alcatraz! I just don’t know that I was ready to completely move there. When I began at the school I struggled to meet new people and find my way within the school structure. I was convinced that there was something wrong with me, and that I had trouble meeting people because I was so extremely different that I would never be able to assimilate. Every day at 11:30 I would get a feeling of dread in my stomach knowing that I would soon have to go to lunch and amble awkwardly around, pretending that I actually had a group of people to eat with, and then subtly sit down by myself at a table outside, eating, and wishing that the next bell would just ring so I could slink away to Math class. Even the quadratic formula would beat this. Mysterious Disappearance I realized that eating by myself everyday and spending my weekends watching Full House re-r uns wasn’t the most ideal way to be spending the glory days of my youth. I became frustrated. When I would sit alone I would imagine the life I wish I had. I’d watch the football players laughing with cheerleaders at their table and think they were just lame anyways. I was smart. I thought about things like philosophy and books and Ernest Hemingway. So I’d continue eating my sandwich and watch other groups. One day as I was sitting there, observing people, I noticed two guys walking quickly away from the cafeteria, looking around like they were going to escape from prison or something, and then quickly disappear into the woods. I had no idea where they had gone but I was curious. The next day, after I went through the lunch line and got my hamburger, taitor tots, and milk, I walked around and then saw them standing by the vending machine talking. I had to figure out where they kept going. I sat near where they were standing and put on a happy demeanor. After a m oment they stopped talking and one of them asked me what was being sold for lunch. â€Å"Taitor tots,† I said. He laughed and then they walked off. A few moments later, to my great surprise, they came back and sat at the table with me and joked around for a bit. After they finished, they motioned to each other and said goodbye and then walked down the same path towards the woods that ran adjacent to the cafeteria. I knew they were going to enter the woods again. I still had no idea why. The next day at lunch I looked for them again, even sitting in the same place, but they weren’t there. I didn’t think much of it and the day after that forgot the incident had ever occurred. I decided I wasn’t Perry Mason and gradually lost interest. Fitting In This isn’t a story about not fitting in, however, and indeed, after a few weeks I started making an effort to talk to more people. I even met a friend name Franz. Franz was born in Austria and I thought his n ame was a little weird, but he was a cool guy and we both shared the same interests -- we were readers, played basketball, and could undeniably dominate all lesser-beings on the Playstation. Franz introduced me to his friends and eventually I moved to their table at lunch and began joking around and regaining the same social structure I had back in my hometown. The next semester I moved into the International Baccalaureate program at the school. My classes were a lot more difficult, but I appreciated the challenge and for awhile it

My Experiences As a Nursing Student Essay Example | Topics and Well Written Essays - 1750 words - 11

My Experiences As a Nursing Student - Essay Example However, any medical professional can execute the process as long as he or she follows the protocols of medical operations (Callara, L. 2008, 57). The criterion (protocol) that must be followed, starts with checking the absence of possible air leaks into the bottle of a chest drain. Air leaks are usually noted when a patient breathes out using force or coughing with vigor, unlike normal exhalation. Secondly, a check-up for the fluid volume into the chest drains to establish if it is normal or low follows. If it minimal, say, 10ml per hour, chest drain is usually present (Daly, J. Speedy, S. & Jackson, D. 2009, 68). The establishments of a respiratory difficulty also define that there is a chest drain problem. Similarly, an increased bleeding risk that is associated with a decrease in coagulation also shows that there is a chest drain. Having established the explained steps, evidence from radiology for the absence of air or accumulation of fluid in the chest will be required before th e removal of chest drain process begins (Jacob, A. & Sonali, J. 2007, 29). My work in the whole chest drain process was to prepare the equipment used for the procedure and care for the patient since before and after the procedure, the patient is put under a closed –chest underwater seal that drains air and fluids to enhance the expansion of lungs (Basford, L. & Slevin, O. 2003, 39). The equipment I prepared for the doctor to carry out the procedure was a sterile dressing pack, gloves, stitch cutter, a solution for the cleansing of the skin, a clinical waste bag, a sterile swab, clamps and a dressing that is non-adherent (Quinn, F. 1998, 45). The predominant procedure is ensuring that the patient lies in an upright position to guarantee the expansion of lungs so that there is easy optimal drainage of air and fluids enhanced by gravity (Fagin, C. 2000, 40).  Ã‚

Bureau of Correction Essay Example for Free

Bureau of Correction Essay Corrections in the Philippines started during pre-colonial times when the task was community-based. It was only during the Spanish regime that an organized corrective service was made operational. The main penitentiary was the Old Bilibid Prison at Oroquieta Street in Manila which was established in 1847. It was formally opened on April 10, 1986 by a Royal Decree. About four years later, on August 21, 1870, the San Ramon Prison and Penal Farm in Zamboanga City was established to confine Muslim rebels and recalcitrant political prisoners opposed to the Spanish rule. The facility which faced the Jolo Sea had Spanish-inspired dormitories and was originally set on a 1,414-hectare sprawling estate. When the Americans took over in the 1900s, the Bureau of Prisons was created under the Reorganization Act of 1905 (Act No. 1407 dated November 1, 1905) as an agency under the Department of Commerce and Police. It also paved the way for the re-establishment of San Ramon Prison in 1907, which was destroyed in 1898 during the Spanish-American War. It placed under the auspices of the Bureau of Prisons and started receiving prisoners from Mindanao. Before the reconstruction of San Ramon Prison and Penal Farm, the Americans established in 1904 the Luhit Penal settlement (now Iwahig Prison and Penal Farm) on a vast reservation of 28,072 hectares. It would reach a total land area of 40,000 hectares in the late 1950s. It was located on the western most part of the archipelago far from the main town to confine incorrigibles with the hope of rehabilitation. The area was expanded to 41,007 hectares by virtue of Executive Order No. 67 issued by Governor Newton Gilbert on October 15, 1912. Other penal colonies were established during the American regime. On November 27, 1929, the Correctional Institution for Women (CIW) in Mandaluyong City was created under Act No. 3579 while the Davao Penal colony in S outhern Mindanao was opened on January 21, 1932 under Act No. 3732. The CIW was founded to provide separate facilities for women offenders. To date, there are two Correctional Institutions for Women, the one mentioned in Mandaluyong and the other one is located in Davao Prison and Penal Farm in Dujali, Davao Del Norte. Owing to the increasing number of committals to the old Bilibid Prison in Manila, the New Bilibid Prison was established in 1935 in the southern suburb of Muntinlupa City. The old prison was transformed into a receiving center and a storage facility for farm produce from the colonies. It was later abandoned and is now under the jurisdiction of the Public Estates Authority. After the American regime, two more penal institutions were established. These were the Sablayan Prison and Penal Farm in Occidental Mindoro under proclamation No. 72 issued on September 26, 1954 and Leyte Regional Prison under proclamation No. 1101 issued on January 16, 1973. The Bureau of Prisons was renamed Bureau of Corrections under the New Administrative Code of 1987 and Presidential Proclamation No. 495 issued on November 22, 1987. It is one of the attached agencies of the Department of Justice. The Bureau of Corrections presently has seven satellite prisons, namely; the New Bilibid Prison in Muntinlupa City, the Correctional Institution for Women in Mandaluyong City, the Sablayan Prison and Penal Farm in Occidental Mindoro, the Leyte Regional Prison in Abuyog, Leyte, the Iwahig Prison and Penal Farm in Puerto Princesa City, Palawan, the San Ramon Prison and Penal Farm in Zamboanga City and the Davao Prison and Penal Farm in Dujali, Panabo, Davao Del Norte. Of these prison satellites, the New Bilibid Prison in Muntinlupa City as the Central Office serves as the main penitentiary as the Central office is also located in there. As of August 2012, the total population of prisoners confined in all satellites of the BuCor is 20,000. It is at this juncture, that handling, managing and taking care of the records of these inmates are of complex types of work which have to be performed by the competent personnel assigned at the â€Å"Inmate Document and Processing Division.†

The Cause and Effects of Terrorism

The Cause and Effects of Terrorism In this modern world, terrorism has become a hazardous threat to all the countries around the world as it will cause devastating casualties and economy impact in any of the countries. According to Krueger and Maleckova (2003), the term terrorism is defined as premeditated, politically motivated violence perpetrated against noncombatant targets by subnational groups or clandestine agents, usually intended to influence an audience. Terrorism is basically an act of the terrorists to convert a message such as ideological, religious or political object through violence or destruction. The more destructive it is, the more audiences they will have. Thus, terrorists will be greatly increased if they can influence people around the world to achieve the objectives or goals that the terrorists group has plotted. In addition, there are factors that made other people to join terrorism and the effects of it. While terrorism is still in active around the globe, what has causes this dreadful act that harm many people live and property and what are the reasons behind this Keet (2003) stated that one of the causes is formation of nationalist or separatist. He emphasize that colonized nations which made nationalist movement has a high chances to become a terrorism organization. Mahatma Ghandi was the only one who gets along with the freedom movement without using any violence act. Extreme nationalism, on the other hand, has set up or upholds language rights, religious belief and symbols. They persuade on a regional-ethic party and less accentuate on the political rights and privileges. Lawson (2001) too claimed that resistance against an oppressor is a contributing factor that will lead to terrorism. He remarked that the dominance of terrorists land and their people from any oppressor are apparent to have high chances of conducting terrorism. The IRA, the Basque separatist group ETA, the Pale stinians, the Tamil Tigers, the Chechens, and Iraqi insurgents are some of the examples of organization that used forces to fulfill their political goals (Lawson, 2001). Keet (2003) reviewed an important factor that is related to terrorism was social stratification and disproportion of division of limited resources such as food, water and clothing. In this study, lack of economic management has give a huge impact on civilian for their survive needs. Based on the studies shown in Keet (2003) 15% of the population for the poor countries consumes 85% of the overall resources. He stated that if those people cant get a satisfactory amount of resources they needed, they will use force or violence to get what they wanted in order to keep them alive. Thus, these circumstances have formed a new society or organization that will lead to terrorism. The contradictory of theory of disaffected intelligentsia, which is simple minded people that are lack of moral and social knowledge, were the ones that mislead the people (Keet, 2003). They are the reason that dehumanizes terrorists and, in this manner, they wanted to be heard, and acknowledge by the society or the world, that they have the equivalent of human rights. This indicates the inner reason of terrorism, decreeing from the point of its viewpoints, mindset, method of approach and the consequences as studied by Keet (2003). In addition to the dehumanization of terrorists, Keet (2003) claimed that religion is essential cause for the terrorism as it stressed on the Muslim extremists in the Middle East. The research showed that Islamic terrorism rejects the ideology of democracy and individualism, while Islamists dislike the concept of capitalism and believe in Caliphate (the idea of leading Muslim community in worldwide). People believed that the social issue was connected to the war is the religion and realm which indicates on different belief have a higher chance to engage in a battle than those share the same belief (Keet, 2003). Despite of the above, all religion accentuates that we must treat others as we are wished to be treated and killing is prohibited on most of the religious teaching. In 2004, Borum studied the behavior among terrorists and found out that most of them were perceived from injustice, wanted identity and unfortunately, they were the targeted victims of terrorism. Traumatize from the childhood abuse, they felt injustice as well as humiliated and as a result, they joined the terrorists group as they are the majority in the organization (Borum, 2004). People who search for their identity often trap by the terrorist organization in many ways as one of them is referred to identity foreclosure when the idea or mindset of a terrorist organization is being accepted without serious inspection (as cited in Borum, 2004, p. 25). They often accept the mindset as they couldnt take any more of the complexity and stressful world and they are usually classified as lifeless or monotonous person. Similarly, the studies based on Borum (2004) has emphasizes on the motivation of terrorists as a root to terrorism. Motive is defined as the passion or aspiration to get something done. The opportunity to get into action, the belonging needs, the wish to get acknowledge in society and the acquirement of material rewards are the motivations go get involve in terrorism (Borum, 2004). Moreover, Borum (2004) stated that the remedies of an injustice were the essential motivation for terrorism as it can help them to get their revenge back and the best motivation is to help others to avenge but not themselves. The need of belonging that was remarked earlier on has great impact on radical extremist groups as they felt connected and associated with the group. They were expelled and rejected from their society but the organization accepted them and they felt the warmth and kindness just like a family does (Borum, 2004). The causes on terrorism in this world are unavoidable indeed. On the other hand, the effects on terrorism as stated in Bennett and Bray (n.d.) are on tourism industry. After the incident on 9/11, the impact on world travel and tourism council has reported that over 10% of the travel and tourism demand on worldwide has decreased and consequently, 8.8 million people have lost their job in airlines, hotels, tour operators, car rental and credit card companies, thus it decreased 1.7% of total GDP for the world economy (Bennett and Bray, n.d.). With the attacks on the world trade centre, Bennett and Bray (n.d.) reviewed that international arrivals around the world in 2001 has greatly decrease which estimated 4 million that were less than the previous year and it was indicated clearly that people have the fear to take flights. Bennett and Bray (n.d.) stated that it was disastrous for the airlines companies as the passengers numbers were declining. Similarly, AFP (2010a) stated airports and other travel centers as well as tourist attractions across Europe have been heightened with security forces as al-Qaeda has linked with terror plot that targeted in London, Paris, Berlin and other European countries. On the other hand, AP (2010) mentioned on terrorism that was on the alert to those Americans living in or traveling to Europe. The economy around the globe has badly influenced from the act of terrorism. As Abadie and Gardeazabal (2007) reviewed that the capital stock, either in physical or human form, has greatly reduced after the act of terrorist in a country. In addition, the country itself needs to increase expenditures on counter-terrorism and in order to get the resources or capital; they need to obtain from their productive industries for the sake of the countrys security (Abadie Gardeazabal, 2007). The incident of September 11th terrorist attacks on US economy have affected the total production assets which decreased 0.06% of it. Walters, Sachsida and Sandler (2006) indicated the stocks in US direct investment has lower drastically after the terrorist assaults against US interest in OECD countries. Similarly, Persitz (n.d.) claimed that due to intense terror in Pakistan, the consumption and government-expense section increases while investment, exports, and imports of production decreases. In the market, people are devastated from terrorist acts as human tragedies happened most of the time. Because of fear, many people didnt want to take the risk to start a business as terrorism could strike anytime and anywhere and eventually it brings down the economy (Market, n.d.). Furthermore, the costs that cover the security purposes were a burden for most of the companies as they might decrease the price of the stock that will lead to disappointment from the stockholders. Market (n.d.) stated that resilience will occurred even if a terrorist attacks, the society will united together to overcome the catastrophe that changes the security system and become more secure and confident than before. For examples in the Kennedy assignation, the World Trade Center Bombing, and the Oklahoma City Bombing. Whats more about effect of the market is the human loss in a terrorist act is heartbreaking news for the victims loved ones. The loss of potential labor workers in a company suffered more hardship than losing profits (Market, n.d.). In 2007, Creekmore (2007) claimed that after the incident of September 11th, social conflict has been arising due to fear and horrified by the incident among citizens. After past few days of the incident, people were lined up around the gas station before gas prices rose two dollar a gallon. The governor of Mississippi took immediate action against local gas suppliers as they were found guilty on raising the gas prices (Creekmore, 2007). Eventually this has set off havoc between the local gas suppliers and customer in different states, and people were fighting for the gas. In addition, Creekmore (2007) mentioned about the rumors which were spread about the shortage of food due to the gas prices and soon everyone felt the state of panic. Media (2008) reviewed that the Internet has many useful functions for the terrorist, such as cyber-terrorism, coordination of plans of attack, communication with cells, or propaganda and information. Convenient, easy to use and access, much quicker to send precious information and inexpensive are the factors for terrorists to use the Internet. As the functions mentioned above, it brings huge impact on the media because the Internet act as a direct medium (Media, 2008). A Mexican-based terrorism organization, EZLN, also known as Zapatistas, has brought catastrophe to its country as it uses Internet to leak information throughout the world. Media (2008) has also remarked that Internet media offensive was started by al-Qaida that their message were translated into European languages and as a result, radicalization process is happening much faster, broader, more mysterious in the Internet era. Instead of having traditional weapons such as sword and spear, The Effects (2006) claimed that terrorists weaponry has stepped forward to a more advance technology, that is chemical and biological weapons. It was dated back then after Persian Gulf, thousands of US troops went home after the war has ended. Unfortunately, they have come across an illness which includes symptoms like chronic fatigue, severe joint pain and headaches, intestinal track problems, internal bleeding, and memory loss (The Effects, 2006). The veterans were then diagnosed with Gulf War Syndrome as a result of war. The Effects (2006) reviewed the terrorists have been doing many illegal activities such as counterfeit the document and statements as well as take apart the equipments and tear down important documents in order to conceal their production of biological weapons. AFP (2010b) remarked the Taliban militants have claimed two raids which around 60 trucks were torched and three people died in this incident. O n the other hand, Pakistani authorities have reported 24 attacks since September 3rd which have claimed more than 140 lives. Over the years, terrorism has caught international attention as it has destructive goals that would bring casualties and economical impact around the world. The research on terrorism was insufficient and the data is not fully complete yet. There are still many unknown causes that would lead to terrorism. However, as times goes by, the secrets behind terrorism will eventually reveal to the world and it must be eradicate as soon as win-win solutions are being discovered and implement into the society.
