Methodological Rigor - Assignment Example Self-selection develops when there is no representation of the samples. The self-selection process gives discretion to the subjects to belong to any group without proper consideration of representation (Vogt, 2007). Essentially, subjects in the study can decide the group to belong, or individuals may assign themselves. The third threat to validity in quantitative research is the volunteer effects (Vogt, 2007). The threat develops when individuals do not give consent for them to be studied. The subjects who participate in the study give different information from the ones who do not give consent. The communication among subjects exhibits multiple complications and can extensively alter information. Maturation occurs due to more time being spent in a study. History effect is a validity threat because it results in extended time being surpassed during a research study (Christensen et al., 2011). There are diverse ways through which the inherent validity threats to quantitative research can be mitigated. Vogt (2007) notes that it is important for a researcher to individual assign subjects to respective groups to deter self-selection. Subjects should be screened carefully to avoid attrition effect. History effect is a fundamental problem that can be dealt with by ensuring that the measurements are taken on every interval. Subjects should not be allowed to control the proceedings of a study (Vogt, 2007). Statistical power refers to the capability of a test to determine with precision an effect and the authenticity of its existence (Black, 1999). Statistical power aid in reducing type I and II errors by correctly determining existence of a relationship or effect (Black, 1999). Ideally, it reduces the incorrect rejection of a null hypothesis in type I error (Peck et al., 2011). Consequently, it reduces the rejection of a null hypothesis because it correctly determines the

Amy Chua's thesis concerning ethnic conflict and free markets Essay

Amy Chua's thesis concerning ethnic conflict and free markets - Essay Example Her hypothesis argues that a state turns into a hyperpower (a state of influence even higher than a superpower) only after it encompasses all ethnic and religious elements under an umbrella where all may co-exist in their own form without any pressure to conform. This, in her view, is the kind of democracy which would pave way for a journey inclined towards turning the state into a hyperpower. Similarly, once this diversity in terms of ethnicity or religion turns into conflict for existence and influence, the state is bound to lose its power and collapse. In order to critically analyze the hypothesis, the socio-economic scenario of the present day China would be taken as a case study and an insight into the ethnic and religious conflicts would be taken to see the deterrence behind China achieving its status of hyperpower. Prior to applying Chua`s hypothesis on present day China, the current power struggle dynamics in China need to be analyzed. Though apparently China is rising exponentially as one of the global economic powers of the world, it is also an undeniable fact the internal dynamics in China pose a threat to the long term development goal of the state, and owing to these internal dynamics, various negative indicators emerge which lead China towards a saturation point. These very internal dynamics deter China from reaching its true potential, despite diplomatic excellence and economic dominance in the world, its position isn`t as close to being a hyper-power as it should be. Since the past 30 years or so, China has been aiming to improve its internal development indicators and its progress in terms of dealing with its domestic issues (Hao & Cho 11). Yet, it`s a given fact that even today China faces many problems at home which include poverty, class gap, inequality, corruption, social reforms , demographic challenges, ageing population and environmental
