WATER FLUORIDATION: - A high degree of reduction in caries/ tooth decay occur when fluoride content is approximately IPPM (i.e. one part of fluoride to one million part of water), the prevalence of oral fluorosis increase greatly when the concentration of fluoride is more than 1pm. Therefore, the optimal concentration of community fluoridation is 1pm. The very first community water fluoridation was in Grand Rapids in USA in 1945 and these produced a reduction in caries between 40-50% in deciduous

Introduction: Literature Review: The globalization of the world, advancement of technology and sharing of information has led to an increase of overseas students studying outside their home country (Sandhu &Asrabadi, 1994). For instance, the quest of seeking advanced knowledge and skills drove my personal pursuit of academic knowledge in America and Britain, having been brought up and raised in Africa. Advanced technology and sophisticated knowledge is part of the reason as to why students seek education

every single day all over the country. There are many reasons and factors that influence a person to engage in criminal activity.

exponential increase of centralizing and categorizing political beliefs, random samples must still be applied to the population. This is important because if one tried to measure a specific sample of public opinion, that includes generalized descriptions, strict guidelines, and specific characteristics of the population sample, then the sample would lack realistic and credible samples of individuals that could potentially fit the sample later on. For example, measuring the public opinion of major, political

of the strengths of the sampling approach is that the external validity is strong for the population of interest: the sample is randomly selected from veterans with PTSD all over the United States. The external validity is not strong for individuals who do not suffer from PTSD, or for individuals who do not live in the United States, as they are not included in the study. The random assignment of the study is also a strength, as this will help reduce sampling error and increase generalizability (Rubin

Breast cancer is the second leading cause of cancer death and one of the most frequently diagnosed cancers among women in the United States (Tang, Patterson, Roubidoux, & Duan, 2009). Screening mammography has been shown to decrease the breast cancer mortality rate through early detection, diagnosis, and treatment. Despite the benefits of screening mammography millions of eligible women are either overdue or have never received a screening mammogram. A program logic model was developed in an effort

a convenience sample where results are biased and questionable. Recommendations The writer recommends not using the collected survey information. The VSO should start over and use the probability method of stratified random sampling so "[the survey] will represent not only the overall population, but also [the] key subgroups of the population..." of subscribers and non-subscribers (Research Methods Knowledge Base: Probability Sampling). To collect names for the random sample, the VSO should
