An assessment of common atmospheric particulate matter sampling and toxic metal analysis methods.
No full textIn this study, the atmospheric particulate matter (PM) was sampled using the tapered element
oscillating microbalance, and the inductively coupled plasma mass spectroscopy (ICP-MS) and
scanning electron microscopy coupled with energy dispersive spectrometry (SEM/EDS) were used for
determination of elemental composition of the PM. The efficiency and relevance of the sampling
method, ICP-MS and SEM/EDS in toxic metal analysis were assessed. Low flow rate yielded high
accumulated mass of particulate matter. The efficiency of the filter media used was found to be, in
decreasing order: teflon-coated glass fiber, ringed-teflon and quartz filters. The main elements
identified from the SEM/EDS on ringed-teflon filters were Si, Fe, Mg, K, Na, C, S, F and O, and for ICPMS,
the following main elements were identified: Fe, Al, Ca, Mg, K, Na, Cr, Ni, Pb, Cu, Zn and Mn. The
ICP-MS proved to be more relevant for the analysis of the toxic metals of interest. The standard
deviations obtained from this method were less than 30% for most of the metals identified. The method
detection limit was also low (0.2 to 1 µg/L) for most metals, and 50% and less standard deviation to
mean ratios were obtained for Ni and Pb
Influence of religious affiliation and education on HIV knowledge and HIV-related sexual behaviors among youth in rural central Mozambique.
No full textThe interactions between religious affiliation, education, HIV knowledge, and HIV-related sexual behaviors among African church youth are poorly understood. In this socio-demographic study, 522 unmarried youth 12-28 years old in rural central Mozambique were surveyed with a structured
questionnaire. Using binary logistic
regression analysis, we used religious affiliation and education to measure influence on (1) HIV transmission and
prevention knowledge and attitudes and (2) HIV-related sexual behaviors among youth. Religiously affiliated males were more likely than non-religious males to know when a condom should be used, respond correctly to HIV transmission questions and respond with less stigma to HIV-related scenarios. Increased levels of education among males corresponded significantly to increased knowledge of condom usage and HIV prevention strategies and less likelihood to respond with stigma. Only education levels influenced young female responses. Religious affiliation and education had minimal effects on sexual activity, condom usage, and multiple partnerships. African Independent Church/Zionist males were 1.6 more likely to be sexually inexperienced than nonreligious males but were also significantly less likely to use condoms (0.23, p=0.024). Non-religious youth were most likely to have visited sex workers and did not use condoms. These results suggest that religious affiliation, possibly as the result of educational opportunities afforded by religious-affiliated schools, is contributing to increased HIV transmission and prevention knowledge among youth in rural Central Mozambique but not influencing HIV-related sexual behavior. The need exists to strengthen the capacity of religious congregations to teach about HIV/AIDS and target non-religious youth with HIV transmission and prevention information
In dubio pro libertate - the General Freedom Right (GFR).
No full textThe constitutional protection of actual, intended or only desired behaviour of a person outside the ambit of a special Fundamental Right or Freedom, requires the recognition of a residual (negative) freedom, also called General Freedom Right (GFR). The non-recognition of the GFR, results in the possibility that the legislator, and in its wake the executive may arbitrarily infringe, restrict and violate the life-spheres of individuals without any legal remedy for the affected individual. Such treatment does not recognise the individual as a recipient of rights but as an object, subjected to statutory mechanisms without a say in the matter. If Ronald Dworkin’s claim that democracy is about governments ‘treating all members of the community as individuals, with equal concern and respect´ holds any appeal, legal scholars better look out for this residual freedom right in their Constitutions. The paper deals with the merits of the GFR and the question where to locate this right in the norm text of the Namibian Constitution

Inner landscapes: An examination of mind style and ambivalence in "The Poisoned Bible" by Barbara Kingsolver.
No full textSet against the back drop of the Belgian Congo made famous by Heart of Darkness by Joseph Conrad, Barbara Kingsolver‟s The Poisonwood Bible depicts the trial and tribulation of a missionary's family and the inner lives of its five women protagonists who travel to Belgian Congo in the wake of the family patriarch, Mr. Price. By presenting the story through the narrative voices of Orleanna Price, the wife of the missionary and her four daughters, Kingsolver explores issues of "double colonisation" of women through colonial and post-colonial times. Western women traveling to Africa during colonization find themselves in a problematic position insofar as they consider themselves superior to the natives or colonized and yet are disempowered within Western patriarchy. In order to cope with the contradictory position in which they find themselves they employ different strategies for survival. The intersection of colonial and feminist discourses in the novel creates ambivalence which is the subject of this paper.
Through my analysis of mind style, I hope to reveal the ambivalence in The Poisonwood Bible. I examine the language of the 5 narrators because each one of them has a unique and distinctive voice, thereby creating inner landscapes for each which are as divergent as they are varied. Through this analysis I would like to argue that a woman's position in the colonial and post-colonial world can only be ambivalent and since The Poisonwood Bible depicts this uncertainty, Barbara Kingsolver succeeds as a novelist
Leveraging the competitiveness of Eritrean agriculture: A case study.
No full textAgriculture is the backbone of Eritrean economy. It provides employment to over 70 percent of the working population in the country. In good years the country produces only about 60 per cent of its total food needs and in poor years, it produces no more than 25 per cent. Annual crop production mainly depends on rainfall that is variable and unevenly distributed from year to
year. Agriculturalists, economists and experts from different fields of studies have raised alarm on food crisis. This paper delves the Eritrean agricultural production, land and people. It throws a light on the Elabered Estate,a reputed agricultural estate since the Italian period. It examines
the strategies and methods used by the Estate to increase agricultural yields. It discusses varieties of grains with greater resistance to disease and pests, together with the use of improved farm management techniques and chemical inputs, such as improved pesticides and fertilizers.
The paper highlights the success story of the Estate being an important player or a model in Eritrean agriculture sector. The paper deals with the concerted efforts made by the Estate to go with the Global Competition. It also highlights some of the challenges of Eritrean agriculture
sector and provides implications
Financial sector development and economic growth in Namibia.
No full textThe main objective of the study was to determine the nature of the nexus between financial sector development and economic growth with specific reference to the amibian economy. The reason why I carried out this study is that no similar study has yet been carried out in amibia and the nature of the relationship between
financial development and economic growth is still not known. This study, therefore, is the first step in attempting to provide literature that could be useful to policy makers and academics in amibia. We used the
Granger causality tests to establish the relationship among the financial sector indicators and economic growth indicators after having carried out the unit root and co integration tests. The results show that the Granger causality between financial development and economic growth is by and large bidirectional. In other words, this means that when the economy grows the financial sector may respond positively and vice versa. We also found that the financial sector variable, the logarithm of the ratio of private sector credit to gross domestic
product (GDP), Granger caused the real variables, logarithm of real GDP, and logarithm of real income per capita. This is in line with the conclusion above that real variables could respond favorably to financial variables. So causality in this case is running from financial variables to real sector variables. The article ended with a cautionary statement on the size of the sample used and the general availability of statistical data on the amibian economy, which could have negatively affected the authenticity of the results

Emerging trends of higher education in developing countries.
No full textQuality in Higher Education has become a primary agenda of the countries worldwide. In the context marked by expansion of higher education and globalization of economic activities, education has become a national concern in developing countries with an international dimension. To cope with
this changing context, developing countries have been pressurized to ensure and assure quality of higher education at a nationally comparable and internationally acceptable standard. It is generally acknowledged that globalization has created tremendous impacts on higher education in this first decade
of twenty-first century. Externally, there have been unprecedented changes both at global and national context. The benefits of globalisation accrue to the countries with highly skilled human capital and it is a curse for the developing countries in frica, Asia, Latin America and Caribbean without
such specialised human capital. This paper delves the recent trends of higher education in developing countries. It addresses the various challenges of higher education in the developing countries in the context of 21st century. Besides, the paper examines the response of higher education to globalization in developing countries and discusses the major challenges that the globalization brought to higher education
