Norm Referenced Test Paper

...assessment technique would be considered a “Norm- Referenced Test.” Norm-referenced test (NRT) are designed to compare test takers, and their scores, in relation to other test takers (Hidden Curriculum). These tests can be very influential when establishing average student performance rates, but have some negative downfalls when the exams are consistently used with low validity. In addition, norm referenced assessments have a very disadvantageous perspective on students within the groups of low socioeconomic status (SES), students with disabilities, and students with second language acquisition. Regarding norm-referenced testing, low socio economic status can play a role in the overall achievement rate of these students. In comparison to families of high SES, children from those of low SES have a decreased amount of educational academic time (Pettigew, p 32). At a young age, students are exposed to many environments, one being a Day Care or pre-school setting. It has been found that students that have a low SES background miss out on the Day Care environment time, and because of that are more likely to have a lower...

Drug Test Research Paper

...Drug Testing In The Workplace Drug Testing in the workplace can seem impersonal and invasive towards employees but it is a process that is done when an employer has reasonable suspicion that employees are using drugs at work coming from a variety of sources such as tips, accidents or behavioral problems, actual observation of drug use, and symptoms of drug usage. Today businesses feel that they have to be well aware that their workplace is a drug free place and that their employees are stable and productive and in doing so, employers result to drug testing. Many feel that drug testing is a good tool to use to have an ideal workplace culture and that most would feel like they have nothing to hide so why object? But not everyone feels the same, others do feel that drug testing like said before, is a violation of privacy and has no sense to be done. Even though one can feel this way that doesn’t make that employee a drug user just that most actually feel that drug testing is degrading. Drug abuse in the work place can affect performance and safety on the job and how an organization see’s it is that drug testing will help eliminate those poor factors. A clear written policy that outlines the employer’s expectations concerning drug use will allow for drug testing in a drug free workplace environment program. The program does have to include training the management on the signs and symptoms that would allow them to perceive with drug testing on employees. Also programs teach...

We will test whether the three sample are from populations with equal variances. This type of testing is called analysis of variance or ANOVA (Lind, Marchal, & Wathen, 2004). The ANOVA test can be conducted with the intent of giving families information on where the best places are to travel on vacation based off gas prices, provide consumers more information on gas prices in different areas of the country for cost of living projections, and enable the gas industry to have additional information on regional pricing standards so they can ensure healthy competition.

The organization is considering three business options; the first involves expanding its growing business to Georgia, the second involves opening a facility located in Maryland, and the third option entails expansion to Florida.

...Week One Overview Why Study the Humanities? As students you are in various degree programs, what does the study of humanities hold for you? Are you really expected to care about any of this? What possible use could it be to you as you move through the various phases of your life and progress in your career? The textbook, The Creative Impulse. Sporre, D.J. 2002, defines the humanities as “those aspects of culture that look into the human spirit.” Study of the humanities traditionally includes the arts, literature, philosophy and history, and within history, the advent of technology and early scientific thought. These subjects contribute to our understanding of what it means to think, to feel, to be motivated to take action and to be human. That still sounds a little distant, doesn’t it? It’s not clear at all what any of this has to do with life as we experience it today. Consider this suggestion; that learning about these people with the strange names who lived in strange places so long ago, will open your eyes to the world around you in ways you never imagined. It will prompt you to think in new ways and to see connections between things you never knew were connected. If a genius is someone who sees connections between things that others do not, it will spark the genius within you. Some would argue that studying the Humanities in today’s cutthroat job market is a luxury we cannot afford to provide to students. The argument follows the lines of practicality...

The average income was $19,500 with the cost of a house $68,700. The average rent ran about $300, with a new car being around $7,200 and a gallon of gas about $1.19. Looking at political history for April 1980, while Jimmie Carter was president he created the “Crude oil Windfall Profits Act” to take advantage of the oil industry’s high profits. Ronald Reagan defeats Carter later in the month of April. The Equal Employment Opportunity Commission prohibited sexual harassment of employees by supervisors in the workplace. Operation Eagle Claw, set up by the U.S. with the intention to rescue 52 hostages from the U.S. embassy in Iran failed due to equipment failure. The new military regime of Liberia publicly executed a number of leading government officials. The United States, France, and the USSR all began nuclear testing at various sites throughout the world.

...Q. Why has the analysis of crimes of the powerful been such a growth area in criminology over the past century? It is tempting to give a simple or even simplistic answer to the above question: it is tempting to say that analysis and theory of crimes of the powerful have grown so quickly in the last century because the quantity and diversity of such crimes have themselves exploded outwards. As the number of crimes committed by the powerful have risen exponentially across the years and continents, so the police forces, crime-prevention agencies and legislators of the governments charged with halting these crimes have had to evolve into larger and more complex organizations also. For instance, amongst myriad forms of organized crime that developed in the twentieth century, one pertinent recent example is the efflorescence of high-tech and internet crime, where professional and international gangs manipulate technology to extort or steal large sums of money from the public. High-tech crime is of course a recent phenomenon; it did not exist at the turn of the last century. Therefore analysis of such activities by law agencies has grown to respond to this new threat; moreover, the analysis and prevention of such crimes has had to grow in sophistication and size just as the crimes themselves have done. Organized crime - be it narcotic trafficking, prostitution rings, corporate crimes and so on - has become a massive international business, and it has required larger agencies equipped...

...Exo-Vaticana Is Rome actually moving the religious world toward a definite revelation, a momentous disclosure concerning extraterrestrial intelligence that will impact the religion of Christianity? Cris Putnam and I fully expect a barrage of criticism from all sides from the release of our new book, Exo-Vaticana. On one hand, many who believe space aliens are visiting Earth from other galaxies are going to take offense, and, on the other hand, many skeptical Christians will charge us with sensationalism. However, we believe we have good grounds for the ideas behind this book, and if one is willing to engage in the arguments, they will stand up to scrutiny. Even so, a few caveats are in order: First: The UFO/ET subject is murky water, to say the least. But once the hoaxes, hallucinations, and nonsense are extracted, there is a genuine unexplained phenomenon. Second: We are not taking a hard line on the existence of extraterrestrial life, but we do make a case for why we are skeptical. Third: We are not generalizing that all paranormal (another vague category) phenomena are necessarily demonic, but we are basing our epistemology on the proven guide to the supernatural, the sixty-six books of the Bible. The Arrival of an Alien Savior Currently, the group of beings referred to as “aliens” are…preparing the earth for a massive…paradigm shift, while also continuing the education that they maintain is crucial if the human race is to be spared destruction.
