The purpose of this study is to investigate correlation between Research Paper

The purpose of this study is to investigate correlation between adolescents that watch television more than 4 to 5 hours per day - Research Paper Example Apparently, the California Department of Public Health found that out of every nine children, one is obese (Hennesy-Fiske, 2011; Lee, 2006). In fact, other authors even pointed out the fact that obesity amongst children is more prevalent in California than anywhere else in the United States (Henessy-Fiske, 2011). The following are the main causes of sedentary lifestyle in the said state: (1) having a sedentary lifestyle which is characterized by lack of exercise and excessive computer use for non-academic matters; (2) popularity of fast-food options and the lack of fresh fruit and vegetables; and finally, (3) excessive consumption of calories. In studying obesity (cite) in the State of California, it was noted that obesity is higher in low income areas suggesting that the African American as well as the Hispanic population are more exposed to this problem than the others (News Information Bureau, 2005). Recognizing the seriousness of the problems related to obesity, authors (cite) su ggest the following measures to be able to address the said matter at hand: (1) the promotion of active lifestyle; and (2) cutting down the intake of calories by fifty percent. Research Aims The purpose of this study is to investigate correlation between adolescents, aged 13-17 who watch television more than four to five hours per day and childhood obesity in Southern California. Research Objectives In particular, the following objectives are pursued: 1) To have a baseline assessment of the extent to which 13-17 years olds in California practice sedentary lifestyle habits; 2) To ascertain the prevalence of obesity among this age group in California; 3) To determine if a child’s family environment is associated with childhood obesity. 4) To establish if there is a significant correlation between sedentary lifestyle habits and obesity in this age group; 5) To recommend interventions that may lessen the prevalence of obesity among them. Literature Review This portion of the prop osal presents pertinent literature which the researcher considers paramount in establishing the conceptual, theoretical and empirical underpinnings of this study. Parenthetically, the researcher deems the literature review of paramount importance to provide the answers to the questions enumerated in the preceding chapter. Without a doubt, obesity is one of the most common problems experienced in the United States of America. The prevalence of this problem has been brought about by the preponderance of sedentary lifestyle as well as too much consumption of fast food. Nevertheless, it has been argued that aside from the above mentioned, obesity is also caused by the environment wherein a child lives in. In this regard, once again, this chapter focuses on the above mentioned topics in order to gain a better understanding of the topic at hand. Correlation between Sedentary Lifestyle and Childhood Obesity This section of the literature review has then been devoted to the discussion of st udies, journals and articles earlier published that look into the correlation between sedentary lifestyle and childhood obesity. These suggest that having a sedentary lifestyle is one of the most common causes of childhood obesity. Evidently, complexities arising from modernity have resulted in the prevalence of sedentary lifestyles. In fact, homes and work sites are designed in such a way that does not really promote physical movement. Thus, engaging in a sedentary lifes

Tom Nowakowski 12/20/13 HI-216 Dr. Pursell Final Exam 1) The Koran has many different things to say regarding the religions being practiced circa 600 AD in the Middle East. Prior to Islam, Saudi Arabia had a lot of people who practiced paganism. When Islam arrived, there was absolutely zero tolerance of pagans and paganism. Things were different regarding Christianity and Judaism. Islam tolerates Christianity and Judaism as they’re Abrahamic religions. The Koran does not have an issue with Christians or Jews practicing their own religious ideas or beliefs. The Koran also instructs Muslims to treat them respectfully and that there should be no forced religious conversions carried out. The Koran also believes that Christians and Jews are people of the book, or people who received scriptures before the Koran was written. The Koran views people of the book, or those who have an Abrahamic religion, as close or related to them. In fact, Islam and the Koran even view Jesus as a prophet and give respect to the Virgin Mary as well. Christ ians and Jews are viewed as misguided but must still be respected. The arrival of Islam drastically transformed the Middle East and its culture. Prior to Islam, women did not have the right to acquire an inheritance, initiate a divorce, and slavery was frequent as well. Muhammad wanted to improve the wellbeing of women and believed they should have more rights. Eventually, Muslim women also were allowed to inherit wealth too. Islam taught that both sexes were equal. Islam also forever changed the way many Middle Eastern countries governed. Many Middle Eastern governments are influenced by Islam or are even officially Islamic countries themselves. This influenced the types of laws that are passed and legi... ...oint where Egypt recognizes Israel and peace treaties between the two have been put into place. Egypt has even become a crucial strategic partner to Israel. Nevertheless, some are skeptical of this Egyptian-Israeli peace and question its effectives. That said, the two are on technically good terms and have diplomatic and economic ties with each other. It’s safe to assume that if such good terms continue in the future, then Israel and Egypt will not have another conflict with each other again. This is obviously important to Israel from defense standpoint too. 6) As of this point, it’s difficult to say for certain whether or not the Middle East will be democratic. Undoubtedly, challenges remain ahead for it to achieve democracy, or at least any reasonable semblance of it. The great hope and narrative that everyone had with the Arab Spring was that

Hume’s Argument for Skepticism

Eryn Croft Professor Chudnoff PHI 101 Honors October 9, 2012 Hume’s argument for skepticism about induction states that we can use induction, like causation, to gain knowledge. We must rely on induction to draw conclusions in everyday life because it is the only resource we have to work with. However, we must realize the limitations of induction. Philosopher Karl Popper successfully undermines Hume’s problem of induction by proving that induction is not needed in science and that Hume’s argument is circular. Karl Popper argued that induction cannot be used in science.He says that induction can never be proven by experimentation. Science instead uses deduction by formulating theories and hypotheses. Science uses the method of conjecture and refutation. Hypotheses can never be proven or verified, but their success can be compared to other hypotheses. The usefulness of a hypothesis can be determined through deduction or predictions. Scientists test theories by makin g completely falsifiable claims. If there is nothing you can to do disprove the claim then the hypothesis is corroborated. A corroborated theory should not be considered true, merely accepted until better theories are discovered.Popper said that a theory can never be confirmed by observation. Where Hume argues that our theory originates from repetition, Popper argues that theory begins before repetition. Therefore, Popper argued that science does not even use induction. Karl Popper also argued that inductive reasoning leads to more inductive reasoning, leading to a circular argument. The problem of induction is that induction is creating the problem and â€Å"begging the question. † In order to avoid begging the question when using inductive reasoning, you might introduce a new inductive principle.By introducing a new inductive principle, you would have to make justification based on experience, leading to even more inductive reasoning. Hume argues that we need to justify ind uction, but Popper says it is not necessary because it leads to more induction and hence a circular argument. Popper also completely denies that induction is an a priori synthetic truth. An a priori truth is necessary and truth preserving, meaning it cannot be false. If induction is a priori, then it would not require justification based upon experience because it is already true.Since Popper rejects the traditional inductive model in science, he had to replace it with his own approach. Popper chose to accept William Whewell’s ‘hypothetico-deductive model. ’ He said that science does not use the inductive model, but instead uses the hypothetico-deductive model. The model begins by formulating a hypothesis that can be falsified by a test on observable data. We can then experiment or make observations to falsify the theory. Now the theory can be falsified or corroborated. If it is corroborated, then it will be accepted and used repeatedly until a better theory prov es better.In Hume’s view, observation comes before theory, whereas Popper’s view is that theory comes before observation. Popper believes that having an observation without first considering a theory is pointless. He argued that theories are only scientific if they are capable of being refuted by tests. As a result, Popper thought that falsifiability and testability were synonymous. One of Popper’s biggest arguments against Hume’s theory of induction is in his explanation of corroboration. A theory can only be corroborated if it does not contradict the basic, accepted statements.Even if a theory is falsified, we can still find many areas of corroboration. If a theory is highly falsified, then it is also highly corroborated. Needless to say, a falsified theory cannot also be considered corroborated. Merely, we can find corroboration through the steps taken to falsify a theory. Popper also acknowledges that corroboration is relative to time. He wanted to en sure that corroboration was not used to determine truth or falsehood. Although Popper successfully undermines Hume’s argument for skepticism of induction, there are also problems with Popper’s argument.Scientists always repeat experiments in order to ensure that the results are accurate and valid. An experiment cannot be proven correct unless other scientists replicate the experiment and achieve the same results. However, Popper argues that scientific knowledge is created by conjecture and criticism; but repeating experiments is not conjecture or criticism, it is induction. You would not repeat experiments for conjecture because it would be repetitive and unnecessary. Repeating experiments is in fact induction because it is allowing for the possibility that the conclusion is false.For example, if all of the Ibis we have ever observed are white, we can induce that all Ibis are white. This observation about Ibis is not conjecture because our past experiences offer suffic ient proof that all Ibis are white. Induction is based off of past experiences and repetitive observations. Therefore, scientists’ repeating an experiment is in fact induction, not conjecture or criticism. Scientific knowledge is an infinite cycle of inductive logic. Inductive logic continuously replaces one theory, with a better more inclusive theory that also relies on inductive logic. In addition, science does have theories that they think are proven.When scientists create a law, it is based on a theory proven through induction. For example, Isaac Newton was sitting under an apple tree when an apple suddenly fell next to him on the ground. Newton used his observation to conclude that gravity was the force that caused the apple to fall to the ground instead of merely floating in the air. Newton, by direct observation and repetition, proved the Universal Law of Gravitation. Popper argued that theories proven corroborated should not be considered true. But gravity can in fact only be proven true through induction, not conjecture.Newton did not attempt to continuously falsify gravity, but instead continuously prove gravity through causal relations. If the apple always falls to the ground and always has in the past, then we can use inductive reasoning to assume that gravity is the cause of the fall. Finally, scientists must use prediction as part of methodology in science. Popper says that theory comes before observation. Prediction is the majority of proposing a theory. We cannot use Popper’s ‘hyptothetico-deductive model’ without the methods of induction because probability is part of induction. Induction allows us to predict the outcome, and thus create a theory.Induction is included in Popper’s own models, which negates his claim that science does not use induction. Hume’s argument for skepticism about induction has many valuable points that allow us to conclude that induction can be a valuable tool in drawing conclus ions; we just have to be skeptical when using induction so we are not misled. Karl Popper successfully undermines Hume’s argument, but there can also be objections to Popper’s argument. As a result, it is best to combine Hume’s argument with Popper’s argument. First, we can accept Popper’s claim that deductive arguments are usually always rationally and logically true.For example, the word bachelor will always be accepted as someone who is unmarried. We can also realize that when using induction, there is always a gap between the premises and the conclusion. We must use probability and past observations to reach a conclusion and close the gap between premises. However, we cannot assume that Popper’s method of falsifying theories and corroborating theories to necessarily be correct. Hume believes that observation comes before theory, while Popper believes that theory comes before observation and is then proven false.Attempting to falsify stat ements is actually using inductive reasoning, so Popper is not absolutely rejecting induction. As a result, we cannot absolutely reject induction either. We must also accept that induction is definitely a priori, definitely truth preserving. It is a known fact. However, an a priori truth is based on probability and enquiring. For example, we cannot say bachelors are not married without enquiring about people we know to be bachelors. Thus, we still use induction and cannot rule it out in the scientific process. As a result, we can argue that science uses both inductive and deductive methods to reach conclusions.

Questions On Securing Wireless Client Devices - 957 Words

5. Securing Wireless Client Devices Two major threats to wireless client devices are (1) loss or theft, and (2) compromise. Many of us store our confidential and proprietary information in our Laptops and PDAs, loss or theft of such kind of devices may cause the organization to be in violation of privacy regulations involving the disclosure of personal identifying information it has collected from third parties. Another threat to wireless client devices is that they can be compromised so that an attacker can access sensitive information stored on the device or use it to obtain unauthorized access to other system resources. 6. Securing Wireless Networks 6.1 Use of Encryption The best way for securing the wireless networks from hackers or†¦show more content†¦The user has to turn off the broadcast the information if the user is not present. Hackers can use identifier broadcasting to home in on vulnerable wireless networks. Disable the identifier broadcasting mechanism if your wireless router allows it. 6.4 Change the identifier on your router from the default By default the router comes with standard ID assigned by the manufacture of the hardware of the router. Suppose even if the router is not broadcasting the SSID the hackers can compromise the network by using the default IDs and can access the network. So try to change the SSID to something which you can remember easily and configure your computer to connect to it. Use a password which is alphanumeric which cannot be easier for the hacker to break. 6.5 Change your router’s pre-set password for administration Like changing the identifier of the router we have to change the default password of the router, which allows us to setup and configure the router. Hackers can easily guess the default password and able to compromise the system. The tougher the password, the harder it’ll be for the hacker to crack it. 6.6 Allow only specific computers to access your wireless network Computers can able to communicate with any network with a unique Media Access Control (MAC) address. The routers have a mechanism to allow or connect only the devices which have a particular MAC address. Some hackers can also spoof MAC address. 6.7 Turn off your wireless
