Token Economy Essay Example

Token Economy Essay Example Token Economy Paper Token Economy Paper The mode of action of Token Economy aims to increase the frequency of a patients desirable behaviours and decrease that of the undesirably behaviours. Tokens are used to dignify reinforcement and are used as part of a reinforcement schedule. Punishment is implemented by the withdrawal of tokens. There are six main steps: 1. the target behaviour is identified (reinforcement or punishment)  2. the nature of the token is identified  3. depending on how many tokens individual receive over the day, they will get a certain number of desired items.  4. the exchange rate is determined (20 tokens for 1 chocolate bar)  5. the location and time of day in which the tokens are exchanged is determined. Allyon and Azrin (1968), pioneered the Token Economy system, found that tokens were most effective when associated with behaviours already in a patients repertoires.  OLeary et al (1969) had no success witgh a behaviour modification programme byt found that a Token Economy system reduced disruptive behaviour in 5 out of 7 children studied.  Token Economies are important because, even though the introduction of chemotherapy in the 1950s meant that mental patients could live in community settings, this transition to community living required more than symptom reduction; living skills also had to be improved. (Lecomte et al, 2000). Most studies do not indicate whether desirable behaviours continue when tokens stop or whether the learning that takes place is an institutional setting generalizes to other settings. Furthermore, there is the issue of cure. Behaviour may change, which helps an individual to conduct a more normal life, but the mental illness remains (Comer, 2002). The method is expensive and time consuming: maintaining it required intensive training and concentrated effort, whereas simpler behaviour modification techniques may be just as effective and easier. Finally there is the problem of establishing effective rewards. To be successful, these must be tailored to the individual.  Like behaviour modification programmes, Token Economy is manipulative; Corrigan (1995) claimed that they are also abusive and humiliating. Withholding privileges and basic rights has been rules unethical by US courts (Emmelkamp, 1994).

Physics IA bouncing ball Essay Example

Physics IA bouncing ball Essay Example Physics IA bouncing ball Paper Physics IA bouncing ball Paper 1. Put the ruler perpendicular to the flat surface.  2. Place the ruler in the arm of the metal stand and secure it tight so that the ruler can stay still; it must be perpendicular to the surface and parallel to the stand.  3. Grab the rubber ball and place it with one hand besides the 10cm mark in the ruler.  4. With the other hand have the chronometer in 0 seconds and be ready because as you are going to release the ball you have to start the count in the chronometer.  5. Drop the ball and start the count in the chronometer simultaneously. 6. Wait until the ball to stop bouncing completely, this is, wait for the ball to start rolling so that you can see movement just in the horizontal way or x-axis and not in the vertical way or y-axis, and in that specific time, stop the count.  7. In your physics lab table write the resultant time t for the height h of 10cm.  8. Repeat steps 3-6 twice and write the multiple resultant times in your physics lab table in order to have three time samples. This is for avoiding random errors.  9. Continue the pattern of releasing the ball from each multiple of 10 until reaching 100cm, measuring three times from each multiple of 10cm. Write the results in your physics lab table. 10. Calculate the average of the three times you measure for each multiple of 10cm to 100cm by using this formula:  Taverage= (T1+T2+T3)/3  and write it in your physics lab table in an extra column.  For more accurate results:  -Do not move the experiment while taking your measurements. If you change the place of the experiment, the surface texture, evenness, or slope may change as well, making the results less accurate.  -Use the SAME ball throughout all the experiment; each ball has in general the same characteristics, except that they usually are not perfectly round and they have different sizes and masses. By using the same ball you are increasing accuracy in your measurements. Uncerntanties The uncertainty of the dependant variable, which is the time t, is 0.35 s. This has been measured by subtracting the smallest value to the greatest value of time in every measurement of the height, and then the result of that was divided by 2. It can be better explained with this equation:  After that, the greatest difference of all the results is going to be the one that is chosen to be the uncertainty of time in every measure of height. In this experiment the greatest difference was found in the value of height 80cm, which was 0.35 because. Therefore, 3.5 is going to be the uncertainty of time. All values of time have been rounded to 0.10cm.  The uncertainty of the independent variable, which is the height h, is 0.1cm. This has been settled without any formal guidelines; the factor that just the human eye is used for this experiment and no other more accurate mechanism, gives an uncertainty because the human being is not perfect when measuring something. In this case, the hand can shake at the point of the ruler, or just the perspective of the experimenter can create some error coefficient when measuring the height using a ruler. All values of height have been rounded to 0.1cm.  The following graph was made with Logger Pro Software. I included the uncertainty bars and the computer generated the best straight line and determined the gradient.  Now, the graph is repeated with maximum and minimum gradients based on the extremes of the first and last data point uncertainty bars. Conclusion and Evaluation In Figure 1.3, which is the first graph of our results, there seems to be a direct relationship between the increase of time and the increase of height in the experiment. The straight line that the computer generated shows an increase in both x and y axes which represent the height and the time, respectively.  I can conclude by saying that the experiment of releasing a ball at certain heights, that in this case they were from 10cm in multiples of 10 till reaching a meter, and measuring multiple times to get an average, that in this case was measuring 3 times per measure of height the time it took for the ball to stop bouncing completely and then making a average time, that the hypothesis of height being proportional to time was right and has been proved by analyzing the results and graphs. Time t and the height h were proportional to each other because in the result graph we find a straight line with a slope that proves that proportionality. This makes the experiment successful because the objective of proving the hypothesis was achieved.  After analyzing these factors, the answer to the question How does altering the height when releasing a bouncing rubber ball affect the time until its complete rest in the vertical sense or y-axis? is that as the height increases where the ball is released, it is going to take more time until its rest in the vertical sense, and in the other hand, as the height decreases, the ball is going to take less time to stop bouncing. Problems and Improvement Originally, the experiment was meant to measure the time until the ball reached complete rest (in both x and y axes) so that it could be easy to stop the chronometer and be more accurate. The problem was that the ball would roll on the floor, and as the floor is an even texture, the ball would stop completely taking a lot of time doing it, and sometimes the time it would take to stop in some cases would be very different to other cases because the ball rolls in different directions every time. Changing the experiment of measuring the time until the ball achieved complete rest to measuring time till the ball achieved complete rest in the vertical sense or the y-axis was the solution to overcome this problem. It created a minor problem though. The problem is that the eye cant really see when the ball stops bouncing completely because there are some bounces in the y-axis that cannot be seen by the human eye because they are really minor, making the stopping of the chronometer count a little subjective and decreasing the accuracy of the experiment.

Elderly people should be required to take road tests before having Essay - 1

Elderly people should be required to take road tests before having their driving licences renewed. or The legal age for drinking ought to be lower in the United States as it is in many European countries - Essay Example The older that a person gets, the more their sight and hearing suffer. Their vision becomes bad and many can become blind or develop cataracts. While many wear glasses or contacts when they are driving, there are still those that are in denial about having problems with their eyesight and insist on driving with their eye troubles. The same thing can be said for their hearing; many elderly people resort to hearing aids, but others do not. When these elderly people are on the road without help for their eyesight or hearing, they become less aware of what is taking place around them (Dugan 127). They have to strain to see what is around them, being unaware of merging cars or changing traffic signals, and they may not hear emergency vehicles or cars honking at them to avoid a potential accident. Similarly, their reaction times and reflexes are not as quick as when they were younger. Not only are many of them unaware of their surroundings, but when they are aware they are not as quick to react. If a car is merging into their lane, elderly people are slower to get out of the way, often causing a collision (Schaie & Pietrucha 96). They sometimes merge into another lane without noticing another vehicle; if the other vehicle were to honk, the elderly driver might not hear it, and if they do, they might not be able to merge back over in time. Many car accidents are caused by the elderly because of their inability to react quick enough to avoid an accident, such as accidents in which they mistake the gas pedal for the brake and are unable to correct their mistake in time. With old age comes many health issues, and with these health issues comes medications with horrible side effects. Elderly people can experience heart attacks while they are driving, which can cause accidents; many of them are also driving while experiencing certain disorders, such as dementia or Alzheimer’s disease. While these

Compare two company - Essay Example Charles Boot headed the efforts of company to obtain various government contracts during the war period. It is rather an achievement that 1000 military buildings and over 50 miles of roads were constructed within one year during Great War. During the years 1919 – 1939 inter-war period, Henry Boot built over 80,000 houses which were more than any other contractor in United Kingdom. Henry Boot Plc under the leadership of Charles Boot developed Pinewood Studios at Heatherden Hall, Iver, Buckinghamshire during 1936, which was based on the layout and practice of USA film studio. The company acquired Baldry, Yerburgh and Hutchinson Limited and Flettons Limited and company started to undertake all types of construction work, large and small, both for the public and private sector. Company’s turnover continued to increase in the areas of building and civil engineering which included long term contract for the National Coal Board and British Steel Corporation, railway engineerin g contracting, joinery manufacture and houses for sale. Henry Boot Plc formed subsidiary in the name of Banner Building Society to offer mortgages to general public for commercial and residential properties. The expansion of Henry Boot Plc continued with the acquisition of a foundry in Bingley, West Yorkshire in 1974 and during 1976 the company saw an increase in overseas work initially with the collaboration of Hong Kong based Gammon in supplying and laying the tracks for Mass Transit Railway System followed by  £13 million railway sub-contract on the Kowloon-Canton Railway in Australia. Later, Henry Boot Plc acquired Thos W. Ward (Railway Engineers) Limited of Sandiacre in order to strengthen the group’s railway engineering activity which was followed by the prestigious Queen’s Award for Export Achievement. The company’s core activities are property development, land management, construction and plant hire. Presently Henry Boot Plc is

Video games Essay Example for Free

Video games Essay Today, video games have become the most popular means of entertainment throughout our world. More than three-quarters of American youths have video-game consoles, and on a typical day at least 40 percent play a video game. Moreover, recently there has been a wide range of studies by professors throughout the world all focusing on the idea of whether or not video games are causing the youth to become a more illogical violent society in the future. Moreover, some people believe they are just a waste of precious time. However, they have been proven by many scholars that they are not only the best means of entertainment, but also one of the best sources of learning and improving brain performance and strategies, speed of alertness and decision making, and problem solving skills. Coming up with good strategies can be very handy for our lives whether it be in business, learning, teaching, etc. Nowadays video games have been proved to make people smarter towards creative strategy thinking. For example, it has been stated that â€Å"While there are many games that place a premium on strategy, most set an overall goal and give the gamer numerous ways in which he or she can achieve that goal. † Vila, Monica. 7 Reasons Why Your Son Should Play Video Games. http://www. babble. com/. N. p. , 04 Feb 2013. Web. 4 Nov. 2013. Video games teach kids to think objectively about both the games themselves and their own performance. In addition, players also get instant feedback on their decisions and quickly learn their own strengths and weaknesses through try and error since they get unlimited lives in a video game. Video games have a great effect on the youth regarding decision making. Some researchers compared action video-gamers and non-gamers with a series of simple decision-making experiments. Gamers devoted at least five hours weekly in the year before the experiment to playing action video games, such as Grand Theft Auto: San Andreas and Halo 2. They presented volunteers with arrays of dots, asked them to identify which way the dots were moving, and varied the number of dots moving in the same direction to make the task easier or harder. Video games get kids to think. There are dozens of video games that are specifically geared towards learning, but even the most basic shooter game teaches kids to think logically and quickly process large amounts of data. Rather than passively absorbing content from, say, a TV show, a video game requires the player’s constant input to tell the story. Moreover, well known sources such as the video games CQ research proved this characteristic about video gaming â€Å"Games stress taking your knowledge and applying it. That’s pretty crucial in the modern world,† says University of Wisconsin Professor of Reading James Gee. † Glazer, Sarah. Video Games. Congressional Quarterly, 2006. 939. Print. Indeed, the argument that video and computer games are superior to school in helping children learn as gaining currency in academic circles. Claimed benefits include improved problem-solving, mastery of scientific investigation and the ability to apply information learned to real-life situations. In conclusion, as you have seen, there is more than just killing and violence in video games. Our future children should be more exposed to video games not only for ways of entertainment, but also for the sake of improving their intelligence whether it be in creating new strategies, enhancing problem solving skills, or even allowing them to make better life decisions.

How To Surf The Internet :: essays research papers

How to Surf the Internet The term "Internet," or "The Net" as it is commonly in known in the computer business, is best described as an assortment of over one thousand computer networks with each using a common set of technical transfers to create a worldwide communications medium. The Internet is changing, most profoundly, the way people conduct research and will in the near future be the chief source of mass information. No longer will a student have to rely on the local library to finish a research essay - anybody with a computer, a modem, and an Internet Service Provider can find a wealth of information on the Net. Anybody with a disease or illness and who has access to the Internet can obtain the vital information they are in need of. And, most importantly, businesses are flourishing at this present day because of the great potential the Internet holds. First of all, for a person to even consider doing research on the Internet privately they must own a computer. A computer that is fast, reliable, and one that has a great deal of memory is greatly beneficial. A person also needs a modem (a device that transmits data from a network on the Internet to the user's computer). A modem's quality and speed are measured as something called a baud rate (how fast the modem transmits data in bits and kilobits - similar to grams and kilograms). A kilobit is a term simply used to describe the speed of a modem. For example, if somebody was to go out and purchase a 2400 baud modem, they would be buying a modem that transmits data 2400 kilobits per second which is definitely not the speed of a modem you want if your thinking of getting onto the Internet. The speeds of modems then double in the amount of kilobits that can be transmitted per second going from 4800 baud to 9600 baud and so on eventually getting up to 28800 baud (which is the fastest modem on the market right now). To surf the Internet successfully, a person will have to own a 9600 baud or higher, and with recent advancements the Internet has offered, the recommended speed is a 14400 kilobytes per second modem. A modem ranges in price, depending on the type of modem you want, the speed you need, and if it is an external or internal type, modems range from as low as $20 to as high as $300. If a person is unequipped with a computer most local libraries and nonprofit organizations provide Internet access where research can be done freely.

Cheerleading Captain Essay

There are many different opinions out there about cheerleaders, many good, and many bad. Some think of them as the girls standing by the football field, but I think of cheerleading as a symbol of all the spirit that we can share, and a token of appreciation toward the team that’s being cheered on. Cheerleading is such a vital part to many sections of the school. If I, Nina Guenther, am chosen to be a captain for the Burrell High School Junior Varsity squad, I will make sure that everyone has a positive outlook, and the great qualities the squad holds are emphasized.One reason I’d make a great choice for a captain, is that I would be dedicated to the squad, and won’t give up when faced with an obstacle. To me, extra practices, time spent making cheers, organizing stunts, and many of the other things a captain is chosen to do, is not work, but a privilege. These tasks would not bother or frustrate me, because as long as it’d help the girls on my squad, Iâ₠¬â„¢d be happy to do anything to help. I’d handle all obstacles, whether they concern individuals, the squad, a cheer, or a stunt, in an effective way that would help the squad grow.If I were chosen, I’m sure that I could help the squad surpass past years, and I could help every girl on the squad grow and become a better cheerleader. I have a strong belief that the change and growth in others affects you. I remember as I walked into the first tryout practice, last year, how nervous I was. I worked hard throughout that season to sharpen my physical and mental skills. Even though I’m far from perfect, if I continue to learn and get better, then I will influence and persuade others to do better.Growth will not only be seen in the abilities of the squad members, but in their attitudes. If I were a captain, I would make sure that everyone kept a positive outlook and worked harder than ever. Hopefully, by the end of you reading this, you can see how dedicated I am to this squad, and how hard I’ll work to make sure this season is one of the best we’ve ever had. I see a lot of promise in this year, and if I’m chosen as a captain, this squad’s full potential will be realized. Cheerleading, to me, isn’t just about standing on sidelines yelling cheers.It’s about how a group of people can support another group through their spirit. It’s not about bows or matching outfits, either, it’s about how people can come together to achieve something. Finally, it’s not about standing in rows, it’s about how if we can all come together to support something, we can make a difference. It’s about friendship and teamwork, hard work and dedication. Please consider me as a choice for one of the captains for the 2013-2014 cheerleading season on the Burrell High School Junior Varsity Squad. Thank you.
