Should the U.S. build a National Missile Defense System? Essay

Should the U.S. build a National Missile Defense System? â€Å"What if free people could live secure in the knowledge that their security didn’t depend upon the threat of instant U.S. retaliation to deter an enemy attack?† Ronald Reagan; 1983 In his speech of March 23, 1983, President Reagan presented his vision of a future where a Nation’s security did not rest upon the threat of nuclear retaliation, but on the ability to protect and defend against such attacks. The Strategic Defense Initiative (SDI) research program was designed to tell whether, and how, advanced defense technologies could contribute to the feasibility of this vision. What is a national missile defense (NMD)? A NMD is in theory â€Å"a technological shield that could destroy all incoming missiles† (Cirincione and Von Hippel 1). A NMD would most likely employ ground-based missiles that would intercept and destroy incoming intercontinental ballistic missiles (ICBM). ICBMs are missiles that are capable of hitting targets thousands of miles away from their launch site. The National Missile Defense Act â€Å"calls for developing a missile-defense system that could protect the United States from an attack by a handful of nuclear armed ballistic missiles† (Ballistic Missile Defenses). It is important to realize the proposed NMD would not be designed to protect against an all out nuclear attack featuring hundreds of missiles. Is a NMD a good thing for the United States? I believe the United States should not develop and deploy a NMD system. How does the NMD work? According to the Federation of American Scientists at fas.org, there are five elements involved in the missile defense system. The first rudiment is the Ground Based Interceptors (GBI). These are the weapons of the system. Their job is to intercept ballistic missile warheads and through the force of impact, destroy them. The GBI includes the interceptor, its launch and support equipment, missile silos, and personnel. The missile is make of an EKV and boosters, and the GBI sites would be capable of holding 20 missiles with eventual upgrade to 100. The next part of the system is called the Battle Management Command and Control (BMC2). This is the brains of the system and it controls and operates the missile defense system. It provides decisive support systems, battle management systems and displays, and also situation awareness information.

Data Types and Why We Care | Written Assignment |

Data Types and Why We Care| Written Assignment| | | | Kayla| 1/30/2013| | Kayla Coleman Wednesday, January 30, 2013 Principles of Testing and Measurements Data Types and Why We Care There are a million different types of data in the world. Some types we have learned through years of education and others have yet to be discovered. One question about data types that is asked frequently is â€Å"Why do we care? † Though there is no text book answer; I believe we care because without these various types of data we will not be able to answer even the simplest of questions.When I think of the definition a simple question I think of a question that can be answered in a few words. A simple question that I would like answered is â€Å"What Is Your Favorite Color? † I have picked this question because it is simple to answer and understand. My method of measurement for this question would be by ranking. For example blue would be ranked the highest because most students liked blue. I have picked basic rating because it is the best way to find the answer that I need without added confusing when it comes to understanding the results.There are many different levels of measurement. All levels have different ways numbers can be used. One level is the nominal level. At this level Numbers can be used for tags or labels like Barcodes and social security numbers. When using nominal variables measurement means is classified as classifying cases in groups. These groups â€Å"must cover all cases† and can not belong to several groups (â€Å"Levels of measurement,†). Ordinal Level is another level of measure. With this kind of measure Numbers are mostly used to order just like in popularity.You have the jerks, the cheerleaders and the Nerds but we all know what order there is. The groups for ordinal variables are ordered but the distance between two adjacent categories may vary. Interval or Ratio Level is the third level of measurement. With Interval or Rati o Levels numbers are used to express quantities like the amount of money you pay for shoes in this case numbers are not just all-inclusive, mutually exclusive or ordered (â€Å"Levels of measurement,†). There are a lot more ways of measuring then we acknowledge like central tendency.Central tendency tells us where the middle of a bunch of data lies. The most common measures of central tendency are the mean, median, and mode. The Mean is the sum of the numbers divided by the number of numbers in a set of data. The Median is the number in the middle or the mean of two numbers in the middle when arranged in ascending or descending order. The mode is the most frequent number in the set (Saccuzzo & Kaplan, 2010). Stand deviation and the Z score are two more types of measure that can be used.The Standard Deviation measures the spread out of numbers. A measure of the more spread apart the higher the deviation. Standard deviation can be calculated  as the root of variance, which is the average of from the Mean. The Z score explains if a score is equal to, below or above the mean of a group of scores. Basically, it compares scores. The normal Z score is between -2 and +2. Anything other than this are considered â€Å"less typical† of scores (Saccuzzo & Kaplan, 2010). Survey research is one way of measurement.Survey research is great when answering of respondents. It can be a paper-and-pencil form or a one-on-one in-depth interview. Scaling is another way of measurement; it deals with the construction of an instrument that relates to qualitative and quantitative metric units. The purpose of qualitative research is to gain more exposure to an area (Trochim, 2006). Qualitative research is good for obtaining very detailed information that allows you to examine the area of interest in great detail.However too much detail does make it difficult to determine what the generalized theme is. An indirect measure is an unobtrusive measure that allows researchers to collect data without doing a formal procedure (Trochim, 2006). I believe that a questionnaire would give me the most valid answers to this question. Overall, the large amount of data and measures of data is very overwhelming if you do not know what to look for especially if two methods measure the same thing.However that is a large amount of information out there that can help us clear up the confusing methods of measures this way we can have a valid more efficient research outcome.

How is HIV/AIDS in Uganda Connected to Social Justice...

What is HIV? HIV stands for Human Immunodeficiency Virus which is a virus that attacks the human immune system. Once the body is unable to continue fighting the infection, the disease is more severe and known as AIDS. It usually takes more than 10 years to progress from the HIV virus to AIDS which is a deadly disease that has killed over than 25 million people around the world. HIV can be transmitted between people many different ways. Any kind of unprotected sexual intercourse is a very common way for HIV to be passed on. As well sharing needles, unsterilized tools for tattoos or piercings and exposure in health care settings. HIV can even be passed on to an infant during birth by their infected mother.

Canadian feed the children also works with Uganda Community-Based Association for Child Welfare located in Eastern Uganda to provide home-based-care kits and volunteers who do home visits to HIV/AIDS affected families. UNICEF Canada has HIV offices in 190 countries worldwide, providing antiretroviral drugs for children in more than 50 countries, and in 2009 donated 12 million HIV rapid-diagnostic test kits to those in need. Plan Canada has been working in Uganda since 1992, helping poor children to access their rights to health, education, protection and participation. Specifically helping lower the HIV/AIDS rates in Uganda. They do so by implementing the Prevention of Mother to Child Transmission programme aiming to protect children and their families who are affected by HIV and AIDS. Plan is also empowering people living in poverty, strengthening health and promoting lifelong education. Treatment Although there is no treatment for HIV/AIDS there are ways to lower the chance of getting the virus. In 1986 the Uganda government promoted the â€Å"ABC† strategy which meant abstinence, being faithful to one partner or using a condom. There is also a drug called antiretroviral therapy which is a medication for the treatment of infection by retroviruses, primarily HIV.
