Benefits of Allowing Students to Bring Pets With Them to College

Benefits of Allowing Students to Bring Pets With Them to College To most of us, pets are family and we treat them as such. We give them the love and affection they show us daily. They know when we are sad, happy, or even stressed, and always know how to make our day better. If you’ve grown up with a family pet, it might be hard to leave them at home when you go off to college. Becoming a college student in general is very stressful and eye-opening, especially if you go out of state. Losing one of your best friends can be a tough transition to go through when going through that milestone. Many college students go through stages of depression and anxiety and have almost no way to cope with it. Allowing students to bring pets with them to college is beneficial to them by helping them cope with stress, anxiety, depression, and loneliness. Scientists have concluded many studies proving that animals improve your overall health and well-being. â€Å"A study of women in China found that those who were dogs owners had fewer doctor visits, took fewer days off sick from work, and exercised more often than non-dog owners† (Casciotti, Zuckerman). These results were found because pets, to a lot of owners, are like family and are treated as such. Pets always know when we are sad, happy, or scared. For example, some dogs love to greet their owners when they get home after a day of work, or cats love to purr and rub against you when they want your affection. Studies have shown that no matter your age or disability, pets can you make you feel like you have â€Å"a sense of responsibility and purpose that contributes to their overall well-being† (Csciotti, Zuckerman). Although pets can be very loving and caring, they can also be very messy and hard to keep up with. Depending on the animal, training them can be a daunting task. Cleaning up after them and making sure they arent getting into things they arent supposed to is a struggle for all pet owners. This is why many parents get their kids pets when they are young. Owning a pet teaches the individual about responsibility and what it is like to own something and take great care of it. For example, learning how to teach dogs tricks, how to behave properly, not to beg, and potty train them are just a few ways they can teach you responsibility (Kaye). As child, this can develop into life long skills and help you mature quicker. As a college student, this could help you with time manage ment and learning how to do things independently. College teaches you how to become independent and transition from childhood to adulthood. For some, this is never easy to do. There are always some kids who come to college and arent familiar with how to be independent and not have to rely on your parents all of the time. Many soon dropout due to the overwhelming stress, anxiety, and not being able to handle doing everything on their own. Students come to college and get very homesick as well. This may be the result of missing their family and pets. For most, the hardest thing to do when you leave for college is to leave your childhood pet at home. Transitioning into to adulthood can be a very stressful time in everybodys life. You have to rely on your own income to stabilize yourself and be independent on where you live and find a stable job. Studies have shown that owing a dog through early adulthood can help reduce stress and anxiety. Pet owners in the early 20’s also have a higher success rate in finding a stable job with a living income (Robinson, Segal). Pets can also serve as a companion when lonely. Some can even act as an audience when reciting a big presentation or stress reliever when finals are creeping up. Many students have tried to bring â€Å"Therapy Dogs† to college. Their reasoning is that their dogs help them reduce the stress and anxiety that many young students face daily. Some can even detect panic attacks before they happen and help calm their owner down (Martin). The number of people being diagnosed with depression and ADHD have risen dramatically over the years. The demand for Therapy Dogs have also increased in response. Depression is a growing problem in the teen/early adulthood community. Statistics have shown that students facing stress and loneliness in college are more likely to commit suicide and take their own life. One study showed how owning a pet can reduce loneliness and depression. Theres a reason dogs are â€Å"Mans Beet Friend† and thats because they act as a companion and show you love and affection. Their bright attitudes and soft, furry coat are proven to relieve any anxiety or depression you might have (Casciotti, Zuckerman). College can be a very hard transition for most teens. Most come into college with a preexisting depression disorder. Starting college can be difficult since you are away from home, on your own, and self-dependent. It has been proven that having a pet can help ones mood. From being sad, lonely, and depressed, the subject immediately became happy and excited when brought a dog (Nagengast). The same was done with a cat and the results didnt vary. A study given to California University states that 86% of their students would want to bring their pet to college or would like to have a pet for college (Martin). Some colleges have even agreed to do testing and studies by allowing some students to have a pet for a certain amount of time and compare their work ethic and behavior over those weeks compared to when they did not own a pet. The results showed how students with dogs were happier and more engaged in the classroom. They did better on tests and performed academically and athletically b etter. Their grades went up and became more engaged in the college community. Those who didnt have a pet were more likely to go out and party and put off studying. They would also fall asleep in class, do poorly on school work, and become more secluded (Martin). College teaches you how to become independent and transition from childhood to adulthood. For some, this is never easy to do. There are always some kids who come to college and arent familiar with how to be independent and not have to rely on your parents all of the time. Many soon dropout due to the overwhelming stress, anxiety, and not being able to handle doing everything on their own. Students come to college and get very homesick as well.

When going to college it can be very beneficial to have a pet to bring with you. They help in many ways. They teach you responsibility, improve your mood, and help fight against depression, stress, and anxiety. It is clinically proven that owning a pet can dramatically improve your overall well-being. This can be crucial to a student during a tough time in their life. Having a pet can also decrease student suicides and even student dropout rate. Bringing pets to college will be very beneficial to the students and should be allowed in more colleges and universities.

Week4Journal PHI445 Personal & Organizational Ethics Assignment

Week4Journal PHI445 Personal & Organizational Ethics - Assignment Example 1). Customers value affordability and are willing to shift to cheaper options while competitors discount their products. This occurs amidst high production costs. Competitiveness of the fast food industry, cost of production, and scarcity of resources among consumers are the reasons for the pressure and identifies competitors, consumers, and production resources as the responsible factors to the problem that strains McDonalds’ profit margin. Reducing production costs through retrenching some workers and increasing workload of remaining workers, developing a brand image that will attract and retain customers are some of the possible solutions to the problem. Brand imaging is the better solution because of its focus on the market and its high probability of success through marketing initiatives. in addition and contrary to reducing number of employees and increasing their workload that promises harm to the society, brand imaging promises benefits to the company, its employees wh o will retain their jobs, and consumers who will derive greater utility. Marketing challenges and scepticism are however significant to brand image development (Wong, 2013). Change in taste and preferences challenge the company’s objectives by reducing perceived value of its products and increasing competition from retailers that the changes favour. The changes may be pushed by customers needs or pulled by competitors’ innovation and this identify responsibility of the two classes of stakeholders. The change leads to reduced demand and therefore lower profitability of the organization. Sensitivity to customers’ needs and market trends, and innovation into influencing customers’ taste are the possible solutions. Research based innovation is the suitable solution because of its wide scope and benevolence even though it faces the cost challenge (Wong, 2013).

Astoronomy Essay Example | Topics and Well Written Essays - 1000 words

Astoronomy - Essay Example Ancient Chinese thought Heaven to be of a round shape. The Emperor lived in the highest level. At the center of this heaven is the North Start. Note that for them, the center is the most pivotal part. Ancient Chinese Cosmology had its obvious influences from Taoist philosophy. It values balance, or the harmony of the yin and yang, good and evil. Dualism pervades their thinking, and this has contributed to the rise of two prominent personalities: the Emperor and Imperial Astronomer. The latter is said to use astronomy to predict the future, while the former used the findings of the latter to make decisions. This structured, overlapping thinking permeates their society, and that we cannot help but conclude that astronomy was also part of their life (â€Å"Ancient Chinese Cosmology†). Ancient Chinese astronomers catalogued every star visible to their naked eye. After which they grouped them into constellations called â€Å"palaces† or â€Å"mansions.† (â€Å"Early History of Astronomy – Ancient China†). The ancient Chinese had a systematic way of classifying a star. They assign a particular ordinal number of an asterism to a star. For example, â€Å"the 4th star of name of ‘asterism.’† (â€Å"Chinese constellation†) Scholars consider that ancient Chinese records of astronomical events are very significant for today. The findings have saved modern astronomers if they were to grope from no knowledge. Hence, rapid progress in observation was made possible (Wang, 2006). For example, China had large records of meteor showers. One of those that compiled such records was Shen Kuo in his book Dream Stream Essays. He reportedly wrote: "When stars fall to the earth, they become stones." (Jessie, 2003). China has created and maintained an old but successful tradition in science and technology. This has enabled China to position itself into the forefront of development. As far as Astronomy is concerned, China’s contribution to it

Affirmative Action Essay -- Affirmative Action Essays

The affirmative action program is important because it gives job opportunities for many people regardless of their race, color, religion, gender, and national origin. The work force should be well represented by the different ethnic backgrounds of our society. Some people look at affirmative action as reverse discrimination, but this program doesn’t guarantee employment based on race, ethnicity, or gender. The affirmative action program gives equal consideration to individuals from a different race, ethnicity, or gender, but not one of these factors may be the only factor used to determine an individual’s qualifications for any job. The biggest dispute of the program is the belief that the policy allows less qualified candidates to progress due to different standards for minorities and non-minorities. People need to realize that affirmative action gives balance in the workplace so that everyone from different ethnic backgrounds would be represented in today’s diverse society.   Ã‚  Ã‚  Ã‚  Ã‚  There are few social policy issues that gauge the racial and division among the American people than the affirmative action. Affirmative Action is a term referring to the laws and social policies intended to resolve discrimination that limits the opportunities of people regardless of their race, color, religion, gender, and national origin. Supporters and opponents of affirmative action hold strong to their believes and constantly attack the opposing viewpoints. Advocates believe that affirmative action overcomes discrimination, gives qualified minorities a chance to compete on equal footing whites, and provides them with the same opportunities. Opponents claim that affirmative action puts unskilled minorities   Ã‚  Ã‚  Ã‚  Ã‚   Cannon 2  Ã‚  Ã‚  Ã‚  Ã‚   in positions that they are not qualified for, tarnishes the reputation of minorities that accomplishes success on their own, and violates the Fourteenth Amendment. Since the beginning of affirmative action, the definition has been ever changing in order to satisfy the present beliefs of society. Prohibiting the discrimination in hiring, expanding the filing of application to include more minorities, compensating for past grievances, setting â€Å"quotas† (percentages of a certain type of people that had to be included), have all been part of the definition. As much as many people... ...ould give it a try to acquire a higher education or job training.   Ã‚  Ã‚  Ã‚  Ã‚  Everyone knows that college and military recruiters come to high schools to recruit graduating students, but the school faculty really need to go above and beyond their call of duty to educate students about the different types of programs that will enable students to get a higher education or job training after high school. Young Americans need the guidance and assistance to acquire the tools they need to succeed and one of those tools is knowing about affirmative action; not only what affirmative action can do for Americans, but what Americans can do for affirmative action.

Assignment on Cell Phone Essay

â€Å"Watson, come here: I want you.† This was the first message ever transmitted from one place to another, through a device called Telephone. Alexander Graham bell the American genius along with his assistant Thomas Watson invented this machine in 1876. It was March 10, 1876, an important day for the human civilization when this great machine was invented and it was the first step towards developing the means of communication. Since then we have come across a long way. Various means were added to the means of communication. Today, telephone is a part of our everyday life. Besides telephone, mobile phones are playing a great role to communicate massages from one place to another. It has become an integral part of life in all over the world. Today, telecommunication is one the major part of life. Nowadays, phone is not only using for making calls, among many other functions it’s used for text messaging, multimedia messaging and also even to connect us to the internet. Due to its various functionality it has a greater impact not only in the economy as well as in the society. Bangladesh is talking like never before. The phenomenal growth of the telecom industry over the last two decades has considerable changed the way people interact. The impact is seen among all spheres of people in Bangladesh. But the most significant impact is seen among the young users of cell phone. Telecommunications allows better access to services that enhance a society’s health and wellbeing such as healthcare and social services. Amongst the many implications of research is that poor and rural populations benefit most from mobile telephony because they are least likely to have alternatives. In view of this, the cross subsidies in Bangladesh from mobile to fixed users, from the poor to the rich, are especially damaging. There are a number of ways that mobile services can promote cohesion in families and society. For example, a cheap mobile service allows families and communities to remain as a coherent unit when family members are away for long periods. In cases where a family member is abroad either temporarily or permanently it allows the family unit to remain intact as well as generating inbound international call revenues. Due to intense competition among the operators, every company is trying to provide cheap call rate which is benefiting the users. Young people are benefitting most in this regard since they lack income sources. A cheap mobile service keeps them in touch with families and relatives thus strengthening social bodings. But every coin has two faces. The telecommunication companies in our country have been inclined towards introducing new and alternative packages for young people like Djuice & Bondhu by Grameenphone, Desh by Banglalink, Shorol by Robi and many more. The question arises why companies are so aggressively coming up with such packages without the social mobilization to check the mindset of youth. How they are facilitating their users by such packages which offer lower call rate at midnight. Except on very urgent occasions ordinarily no one would like to talk after midnight. In our youth segment the majority is student community that is spell bounded by these packages. They are losing their essence of their studies. They are derailing and deviating themselves. They are getting away for their goals, destinies and motives. Their minds are becoming stagnant and static. Creativity and innovation is blocked by the consistent telephonic conversations spread over the whole of night. They are losing their interest towards the interactions and sociality. Alienation is increasing within small community or groups of people. In home young hardly get time to spend with their parents. In one room of hostels all four members are strangers to one another. They never try to tie up the relation because they don’t have a pinch of time. By talking whole night with opposite sex, they are getting psychologically weak and pressured. There are more other physical disorders also experiencing by the youth due to spending the precious time which is needed for compulsory rest, relaxation, relief and mental health. Due to spending whole nights over phone the absenteeism is skyrocketing in every profession. They are going far and far away from the hold of families. They tell lies and have false communication with their parents thus seriously jeopardizing the social relationship. They are deceiving the decisions, trust and expectations of their parents. They are traveling towards the lone parent family system in which one is not accountable to anyone and he is the only decision maker. Suck kind of behavior is leading towards the social fragmentation and terrible decline of moral values in which respect is core one. Even their mental approach is revolving around sexual satisfaction. Other emotions and sentiments are pushed oblivion, they are forgetting that there are so many matters that need their kind attention. Which are making them socially challenged. The mobile companies have every right to work out innovative packages offering greater value of money to their customers. But they should not making profits by compromising on the interest of young generation. Youth spend a huge amount of money on mobile cellular services annually. Major amounts of their disposable income are going to the mobile telecom companies. In the name of competition companies are aggressively promoting their offerings without considering the welfare of the youth. Therefore, we all have to realize the worth and well being of our youth.

Examples of Confidence intervals for means

One of the major parts of inferential statistics is the development of ways to calculate confidence intervals. Confidence intervals provide us with a way to estimate a population parameter. Rather than say that the parameter is equal to an exact value, we say that the parameter falls within a range of values.   This range of values is typically an estimate, along with a margin of error that we add and subtract from the estimate. Attached to every interval is a level of confidence. The level of confidence gives a measurement of how often, in the long run, the method used to obtain our confidence interval captures the true population parameter. It is helpful when learning about statistics to see some examples worked out. Below we will look at several examples of confidence intervals about a population mean. We will see that the method we use to construct a confidence interval about a mean depends on further information about our population. Specifically, the approach that we take depends on whether or not we know the population standard deviation or not. Statement of Problems We start with a simple random sample of 25 a particular species of newts and measure their tails. The mean tail length of our sample is 5 cm. If we know that 0.2 cm is the standard deviation of the tail lengths of all newts in the population, then what is a 90% confidence interval for the mean tail length of all newts in the population?If we know that 0.2 cm is the standard deviation of the tail lengths of all newts in the population, then what is a 95% confidence interval for the mean tail length of all newts in the population?If we find that that 0.2 cm is the standard deviation of the tail lengths of the newts in our sample the population, then what is a 90% confidence interval for the mean tail length of all newts in the population?If we find that that 0.2 cm is the standard deviation of the tail lengths of the newts in our sample the population, then what is a 95% confidence interval for the mean tail length of all newts in the population? Discussion of the Problems We begin by analyzing each of these problems. In the first two problems we know the value of the population standard deviation. The difference between these two problems is that the level of confidence is greater in #2 than what it is for #1. In the second two problems the population standard deviation is unknown. For these two problems we will estimate this parameter with the sample standard deviation. As we saw in the first two problems, here we also have different levels of confidence. Solutions We will calculate solutions for each of the above problems. Since we know the population standard deviation, we will use a table of z-scores. The value of z that corresponds to a 90% confidence interval is 1.645. By using the formula for the margin of error we have a confidence interval of 5 – 1.645(0.2/5) to 5 1.645(0.2/5). (The 5 in the denominator here is because we have taken the square root of 25). After carrying out the arithmetic we have 4.934 cm to 5.066 cm as a confidence interval for the population mean.Since we know the population standard deviation, we will use a table of z-scores. The value of z that corresponds to a 95% confidence interval is 1.96. By using the formula for the margin of error we have a confidence interval of 5 – 1.96(0.2/5) to 5 1.96(0.2/5). After carrying out the arithmetic we have 4.922 cm to 5.078 cm as a confidence interval for the population mean.Here we do not know the population standard deviation, only the sample standard deviation. Thus we will use a table of t-scores. When we use a tabl e of t scores we need to know how many degrees of freedom we have. In this case there are 24 degrees of freedom, which is one less than sample size of 25. The value of t that corresponds to a 90% confidence interval is 1.71. By using the formula for the margin of error we have a confidence interval of 5 – 1.71(0.2/5) to 5 1.71(0.2/5). After carrying out the arithmetic we have 4.932 cm to 5.068 cm as a confidence interval for the population mean.Here we do not know the population standard deviation, only the sample standard deviation. Thus we will again use a table of t-scores. There are 24 degrees of freedom, which is one less than sample size of 25. The value of t that corresponds to a 95% confidence interval is 2.06. By using the formula for the margin of error we have a confidence interval of 5 – 2.06(0.2/5) to 5 2.06(0.2/5). After carrying out the arithmetic we have 4.912 cm to 5.082 cm as a confidence interval for the population mean. Discussion of the Solutions There are a few things to note in comparing these solutions. The first is that in each case as our level of confidence increased, the greater the value of z or t that we ended up with. The reason for this is that in order to be more confident that we did indeed capture the population mean in our confidence interval, we need a wider interval. The other feature to note is that for a particular confidence interval, those that use t are wider than those with z. The reason for this is that a t distribution has greater variability in its tails than a standard normal distribution. The key to correct solutions of these types of problems is that if we know the population standard deviation we use a table of z-scores. If we do not know the population standard deviation then we use a table of t scores.
