Multivariate Techniques - Assignment Example This technique actually examines the relationship between a single dependent variable and more than one independent variable. It is the most common type of method used. It shows a linear relationship holding the lowest sum of the squared variances. The assumptions such as normality, equal variance and linearity and finely and clearly examined by the researcher. A coefficient knows as beta are taken which is the marginal impacts of each variable. This technique is usually used by the firm for its forecasting. This technique is actually the variation of multiple regressions and allows the firms to predict different events. The technique used non-metric dependent variables and the actual objective of the technique is to achieve eve probabilistic assessment of binary choice. The independent variable used by the researchers is either continuous or discrete. Later, a contingency table is formed holding the classification of observations and the observations and predicted results are matched. Then the researcher sum the events that are predicted to occur and they actually occur and sum the events that the researcher predicted not to occur and they actually do not occur. These two sums are added and divided by the total number of events. This shows the effectiveness of the model and helps to predict the choices.

Jeremy Lin Biography Essay Example | Topics and Well Written Essays - 1000 words

Jeremy Lin Biography - Essay Example At the end of the day, experts in the world of professional basketball say one thing – Lin is good but not that good to be a basketball sensation like Bryant or Jordan. I do not agree that he should be a symbol for Asian Americans. Putting up Jeremy Lin as the epitome of Asian Americans is telling the world athletes who are Asian Americans only succeed out of luck which as proven by history is not true. The sensationalizing of Lin has also made China put a claim on his ancestry when he is actually a mixture of Chinese and Taiwanese. Thankfully Lin has not shown any kind of stressing out over his new status symbol which is fortunate because it is too soon to ruin his career like other people who had let their sudden fame get to their heads. Jeremy Lin was born in Palo Alto, Los Angeles to Taiwanese parents who had permanently moved to the United States from Taiwan in 1970. (Taylor) By American law, his nationality is American. His schooling came from American schools. With the guidance of their father, Gie-Ming who was self-taught in the sport, Lin and his brothers learned basketball at the local YMCA. (O’Neil) What started as a way for Gie-Min to release the stress brought about by long hours of work became a way to teach his boys basketball at an early age and a three-nights-a-week routine for him and his boys. (O’Neil) Their mother was on hand to support the hobby but also to make sure that the kids did not lose sight of their academic requirements. Although Lin played the sport really well while in school, he was continuously taunted because of his ethnicity. Basketball was after all America’s beloved sport. Naturally, Americans typical image of a basketball player would be someone like Larry Bird or Michael Jordan - tall and American. Asian Americans were not very common in the scene. When 7-foot tall Chinese national Yao Ming first appeared in the NBA in 2002, a similar hype surrounded him because people were still skeptical abo ut Asian Americans excelling in the sport. Of course, Yao Ming and Jeremy Lin are proving them wrong. It is therefore no surprise that Jeremy Lin’s countrymen, as with Yao Ming, would be so proud of him that they would make him a representation of the Asian American community. Without all the media announcing it, Jeremy Lin is already an inspiration to many Asian Americans. Like how Lin idolized the basketball greats introduced to him by his father, today’s younger generation is also looking up to the promising basketball player. Especially in China where the practice of religion is limited, Lin, who has openly referred to his faith in God many times, has given hope to the Chinese community. For someone as young as Lin, being the image for Asian Americans would be a daunting task that could be detrimental to his career. As with all popular public figures, the young athlete would be in the spotlight at all times. (Zimmerbucher) He would need to ensure that whatever he d oes or says would always please his audience so as not to lose their support. For athletes, performance and mass media are very important aspects of the job. These can play a role in the negotiation of their contracts with their teams and endorsements. Even though this would prove to be beneficial to Lin monetary-speaking, the young man only wants to enjoy the game at this stage in his career. (O’Neil) He also needs to continue improving his skills and he cannot do this with everyone in

Who Gets to Let States Back into the Union Assignment

Who Gets to Let States Back into the Union - Assignment Example Later, Andrew Johnson, a ‘paragon’ of the Southern Unionism, was appointed the military governor of Tennessee by the President, Abraham Lincoln (Para 3). Johnson after being granted control of Tennessee started working for the assimilation of Tennessee with the Union by organizing a civil government based on the principles laid down in the constitution of the United States of America. He stunned his constituents by siding with the Republicans who favored oppressive Reconstruction for the South. Johnson took aggressive and stern action against those not willing to show allegiance to the Union by going to the extent of declaring execution of mutineers. He was very hard with the secessionist powers, and declared, â€Å"Treason must be made odious, and traitors must be punished.† (Para 4) He was firm in his belief that loyal Tennesseans would become role-models for Confederates to embrace the Union but he lacked the diplomacy of Abraham Lincoln. President Lincoln presented in December 1863 the â€Å"Proclamation of Amnesty and Reconstruction† plan, popularly named the 10 percent plan (Para 6). As per the plan, 10 percent of the population would take the oath of allegiance to the Union and government could be organized. Johnson wanted the â€Å"tall poppies† to fall down; he was least worried about the threats from cavalry leaders and citizens (Para 6). Johnson was severe in dealing with the Confederates and Unionists to swear that they â€Å"desire[d] the suppression of the present insurrection† (Para 6). After Johnson became the Vice-President, William Brownlow became the Governor but as the things turned out after the assassination of Lincoln, Johnson became the President. His partial attitude towards white men became the reason for starting an ideological struggle in the White House for Reconstruction.  

Drug Addiction Essay Example | Topics and Well Written Essays - 1000 words

Drug Addiction - Essay Example They crave for the drug so much that they can do anything they could to get a dose for them to relax. For those who are addicted they will continue taking the drugs even after realizing the harm it has on their body. (Amusable, 2008) The risk factors of drug addiction are common as for the other condition. Risk factors include family history of addiction where it is usually common on the families that had prior addiction before the current case. In addition, addiction of drug is dominant in males than female according to statistics. Stats show that the addiction in male is two folds compared with their counterparts. Peer pressure is also a contributing factor. This according to stats is seen mostly in the young people trying to fit in their social stratum. After the first introduction into drug abuse, the body develops a tolerance with time and eventually dependence. Drug addiction is a physiological process on its own. It is a physiologic process, because, it does not just happen at once but develops slowly and in sequential stages. Dopamine is the main hormone that is involved physiologically in the process of drug addiction. Drugs such as cocaine, morphine, and alcohol alter the pathway of dopamine. The first dose taken by an individual has no big effect. Additional drug abuse cause tolerance effect and soon the level of dopamine increase and consequently cause a feeling of being happy. Continuous administration of drugs also has a sensitization effect on the extracellular cells. So when an individual has reduced, or the dose reduce in the blood also the happiness causing hormone, dopamine, also goes down and the craving also start to go back to normal. The drugs taken tend to increase dopamine and when withdrawn the level of this dopamine dwindle and the cycle repeat itself. This cycle is what is known as drug addiction (Hanson, 2005). Will power to withdraw from drugs is most a time futile. The physiologic development of regulation effect

Social Engineering Attacks and Counterintelligence Essay

Social Engineering Attacks and Counterintelligence - Essay Example This essay looks at the concept from the security viewpoint. â€Å"Social Engineering is defined as the process of deceiving people into giving away access or confidential information† (Social Engineering Defined). Hackers, identity thieves, information brokers, disgruntled employees etc. are examples of social engineers. Dr. Max Kilger, co-author of the  Honeynet Project identifies the motivators for non-ethical computer activity which can also be applied to social engineering; these are money, entertainment, ego, cause, entrance into a social group and status within that social group (Typical Goals of a Social Engineer). Counter Intelligence To a layman, counterintelligence would mean the opposite of intelligence seen from the security angle. â€Å"Counterintelligence (CI) can be defined as information gathered and activities conducted to identify, deceive, exploit, disrupt, or protect against espionage, other intelligence activities, sabotage, or assassinations conducted for or on behalf of foreign powers, organizations or persons, or their agents, or international terrorist organizations or activities† (Office Of Counterintelligence, 2011). Implications to National Security New age threats of different kinds according to Car and Musladin (2013) pose a challenge to national security. These are explained below. A few such challenges like terrorism, organized crime, and activism with a negative face are considered here. Terrorism is one of the dreaded scourges that affect national security. As Car and Musladin explain, terrorists actively use the internet to network and carry out physical attacks on nations, who even own up to terror acts on the internet. Organized Crime cannot be far behind. The use of the internet ensures that people at the higher echelons of a terror network go unapprehended and remain free to plan further terror strikes. All sorts of fraud take place by cheating unsuspecting victims. The defrauding of banks and other financ ial institutions can lead to the destabilization of the economy. According to Car and Musladin, activism with a negative face also finds voice on the internet. This can shape and build public opinion. Unfortunately, it can provoke the masses as they can be manipulated by touching raw nerves. On the other end of the spectrum, the internet is also the stage of revolutions and protests. The Arab Spring is an instance of a revolution that took the help of digital media. When mainstream media is muffled or does not offer any succor, it is such media which become the voice of the public and leads to revolutions. Importance of Sound Information Workforce It is of utmost importance that a sound information workforce is maintained. The workforce should be aware of and alert about their work environment at all times. They should be sensitized to the value of the data being handled by them. Only an aware workforce can secure its data. Social engineering also poses a grave threat to security. T he key to preventing this would be a transparent communication system at all times. Impersonation and identity thefts can be reduced to a large extent with a structured communication system. At times, the workforce can sense patterns and peculiarities in routine activities. Hence, corrective action can be taken before further damage occurs. Finally, it is always best to strike at the roots. Any fool proof system to be designed for security is best

Paper Towel Experiement Essay Example for Free

Paper Towel Experiement Essay My wife and I go through an enormous amount of paper products. We discuss often which brand works best for the price. Typically, we buy the brand Bounty for our paper towel selection. There is no particular reason why we buy this brand but it seems to be the one we get home with. After reviewing some other literature in regards to the paper towel experiment, I found some different results. According to Consumer Reports (2009), Brawny was the most absorbent of all of the 21 brands that they tested. They found that Brawny held 2  ½ ounces more per square foot on average than the other brands tested. However another consumer, Chelle from Yahoo’s Contributor Network, found that Bounty was the most absorbent paper towel. She tested Scott, Brawny, and Bounty. (2010) Twelve year old Samantha also performed an experiment on paper towels testing four brands: Bounty, Sparkle, Scott, and Western Family. Her hypothesis was that Bounty would be the most absorbent but after her experiment reported that Sparkle absorbing 50 ml of water on average. (2001) Mrs. McKee’s class from Arizona also did a paper towel experiment. They tested their school’s paper towel, Brawny, Bounty, Viva, Scott, and a generic brand. The results from their experiment showed that on average Viva was found to be the most absorbent. (2012) After looking at other research and preforming my literature review, I decided to test four paper towels: Bounty, Brawny, Viva, and Kroger Brand. I decided that I would use 200 ml of water and place each brand of the folded paper towel in the water five different times. I plan to squeeze the water into a beaker and measure how much water was absorbed. I would then take the average to find out which brand of paper towels was more abso rbent. Problem: What paper towel is the most absorbent and leads to the most cost effective? Materials: 1 Glass container labeled with ml to 750 ml 1 small beaker labeled with ml to 150 ml 1 stop watch 1 baby bottle (I only had one glass container with ml labeled) labeled with ml to 260 ml Paper Towels: Bounty, Brawny, Viva, and Kroger Generic Brand (4 brands X 5 sheets) Water 1 Funnel Pen and Paper Prices on the paper towels were how much I paid per roll, but with further investigation I found that the price per square foot was different. Independent Variables: Brand of Paper Towel, price per square foot Dependent Variable: Amount of Water Absorbed, Vivi sheets were much smaller than the other sheets and two sheets were used and cut to the same size as the other sheets – price is still based on per square foot for each paper towel Constants: Amount of water used in each trial, paper towel size, time exposed to the water, type of fluid (water used) I will make sure to use the timer to submerge the paper towels for the same amount of time. I will use the same measuring instruments for each experiment. Hypothesis: Because Bounty’s roll of paper towel cost the most, Bounty will absorb the most milliliters of water per square foot. I came up with this hypothesis because I wanted to show my wife how we could save money by continuing to buy the name brand paper towel. Data Collection Process: Each paper towel was folded four times to create a small square. Each paper towel was emerged into 200 ml of water and left for 20 seconds. Each paper towel was removed from the water allowing drip time of 5 seconds and then the remainder of the water was squeezed to a beaker. The left over water was poured into a baby bottle for measurement in milliliters. At first I was going to use the amount of water that I could squeeze out of the paper towel, but then I realized that some was still left over in the paper towel. To reduce the threats to internal validity, I then decided to subtract the amount of water left over from 200 ml to get an accurate reading of how much water was actually absorbed. Conclusion: Results from my experiment indicate that per square foot, Viva paper towels are the most absorbent. In addition, since Viva’s price per square foot was 4 cents, it would also be the most cost effective. Viva paper towels absorbed on average 8 more milliliters than Bounty and Brawny and 13.4 milliliters more than the generic Kroger brand. At first glance, Bounty looked like the most expensive paper towel with Viva 2nd. However, when you look at price per square foot, the price of Viva and Bounty are the same. Brawny is actually the most expensive per square foot. With this being said, my experiment refuted my hypothesis that Bounty was the most absorbent because it cost the most. Bounty was not the most cost effective because it did not absorb the most and the price per square foot was the same as Viva. Price per square foot indicated that Brawny was in fact the most expensive and it still was not the most absorbent. It is imperative when doing an experiment that the experiment is done with several trials and that the procedure are completed in the same manner. This adds to the validity and reliability of the experiment. To replicate this experiment, you must have the above materials. Choose at least 4 paper towel brands. Fold each paper towel (five trials per towel) four times. Submerge each paper towel individually into 200 milliliters of water for 20 seconds. Remove the paper towel, allowing it to drip for 5 seconds.  Measure how much water is remaining and subtract that number from 200 to see how much water the paper towel absorbed. Record this and continue the step for each of the remaining paper towels. It is recommended to do at least 5 trials per brand of paper towel. When others perform the same experiment, it validates the results from my experiment. References Chelle. (2010)Which Brand of Paper Towels is the Most Absorbent?
