Discussion #5 - Assignment Example That system renders African nations vulnerable to financial crises in case of a drop in the international market prices. The overreliance on exportation of cash crops confines the African nation’s agricultural sector into subsistence farming, a situation contributing to hunger and starvation in Africa. Hunger and starvation is a major challenge facing most African countries, as food remains a primary and essential need for human survival. The huge population growth in African nations has led to overpopulation leading to high instances of unemployment and dependency ratio in Africa. The high population growth rate in African nations unbalances the available resources leading to food insecurity that is a major challenge in Africa (Ali 15). African colonizers targeted and concentrated on the major cities and trading centers ignoring the villages and interior regions. As a result, imbalance in infrastructural, technological and social development exists between the cities and the rural set ups. With the rapid population growth rate unbalancing the available job opportunities in the rural areas, individuals move to the town centers in search of job opportunities (Ali 13). The migration leads to over population in the urban set up that is a major challenge. In addition, the migration also leads to culture clash and lowers the standards of living in the urban set ups. In effect, it lowers the gross domestic income and productivity of that particular nation. Lack of the employment opportunity in the urban areas eventually results in increased crime rates (Ali 15). These are the challenges confining most of the African nations. Lack of technological knowledge in most African nation’s rural set ups derail embracing of the new and modern western cultures and trends. The long-term effect of this is a complication of interaction between the cultural backward rural dwellers and the town dwellers. Such contrasts lead

Research Methods in Health Science Essay Example | Topics and Well Written Essays - 2000 words

Research Methods in Health Science - Essay Example Ethical principles used in the scientific researches, different approaches to the issues of reality, truth and knowledge and many other aspects of researches would be easily interpreted from the perspective of philosophical considerations (Patterson, 2000; Scanlan, 1986). The main challenge in discussion about research methods applied in health science researches is differentiation between quantitative and qualitative research methodologies (Grinnell & Unrau, 2005). It is a wrong claim that quantitative researches are based on empirical data collection and qualitative researches are based on subjective approach implementation. Nevertheless, this supposition is wrong, because empirical data collection is relevant to both quantitative and qualitative researchers. The main distinction between these two methodologies lies in the following terms: quantitative research methodologies imply inductive inference and qualitative researches are focused more on a research question. ... The main goal of the authors was to consider â€Å"a correlation between clinical features and MRI findings in lumbar disc prolapse in order to define the significance of further treatment development† (Janardhana, Rao & Kamath, 2010). The main clinical features studied among patients were the following: pain distribution, neurological signs, and symptoms in lumbar disc prolapse (Janardhana, Rao & Kamath, 2010). Therefore, the authors were focused on patients’ clinical features, such as lower limb radiculopathy and the outpatient department of orthopedics were included in the study. The authors chose quantitative approach to the current health study. This fact can be proven by the fact that a focus group consisted of 119 patients, 59 males and 64 females. The mean age (44.83 years) of patients and a range of female/male age groups indicated in the results section of the study refers to the main features of quantitative research (Moore, 2008). Moreover, in the section of â€Å"Materials and Methods† it was noted that Kappa coefficient was implemented for assessment of intra- and interobserver variations. Furthermore, implementation of statistical tests (Kappa and Logistic regression analysis) confirms the nature of quantitative research. A correlation between research question and a chosen approach It is relevant to notice that in previous studies in this field, MRI findings were rarely correlated with clinical level and MRI level. A high percentage of cases when the L4-5 disc prolapse was not only responsible for L5 radiculopathy in 67 (94.36%) cases imply that there is a â€Å"good correlation between the clinical level and MRI level† (Janardhana, Rao & Kamath, 2010). Moreover, a
