Study of steroidogenesis in pupae of the forensically important blow fly Protophormia terraenovae (Robineau-Desvoidy) (Diptera: Calliphoridae)

Protophormia terraenovae is a forensically important fly whose development time is studied by forensic entomologists to establish the time elapsed since death (post-mortem interval, PMI). Quantity and nature of ecdysteroid hormones present in P. terraenovae pupae were analysed in order to determine if they could be correlated to the age of pupae found on corpses and thereby could give information on the PMI. Ecdysteroid levels were quantified during the pupal-adult development of synchronised animals using enzyme immunoassay (EIA), a sensitive method allowing acurate quantification in one pupa. Two types of pupae were compared: "fresh" pupae, kept frozen until analysis and "experimentally dried" pupae, which were left for several weeks at ambient temperature. A peak of ecdysteroids was detected between 36 and 96 h after pupariation in fresh animals. It was not observed in "experimentally dried" pupae. High-pressure liquid chromatography (HPLC) analyses combined with EIA showed that 20-hydroxyecdysone (20E) was the major free ecdysteroid at various pupal ages. Enzymatic hydrolysis experiments revealed the presence of apolar conjugates at all ages tested. However, neither qualitative nor quantitative difference was detected between early and late pupae. This study gives precise information on the nature and quantity of ecdysteroids in the course of pupal development of a calliphorid fly. The limits of using ecdysteroid measurement as a tool in forensic entomology are discussed.     

The viability of the welfare state in Botswana

ABSTRACT

Vulnerability, mainly manifesting in poverty, economic risk and insecurities of life, is a universal problem. There are huge pockets of vulnerability in the developing world, particularly Sub-Saharan Africa. Sub-Saharan African states provide social welfare goods to address vulnerability. Social welfare programmes cost money, hence, there is a need to consider issues of sustainability, particularly, given constrained revenue envelopes. Similarly, while Botswana has posted developmental successes, there are vulnerabilities such as poverty, unemployment and income inequality which demand intervention through welfare programmes. Thus, the objective of this desktop study was to discuss the state's response to vulnerability. It concluded that Botswana funds welfare programmes. However, there are affordability challenges, mainly, a constrained post-2007 fiscal space calls into question the viability of the welfare state. The general lesson from the case is that while the welfare state goes to the heart of the social contract, its viability must be guaranteed through reforms.     

Social networks among Indigenous peoples in Mexico

We examine the extent to which social networks among indigenous peoples in Mexico have a significant effect on a variety of human capital investment and economic activities, such as school attendance and work among teenage boys and girls, and migration, welfare participation, employment status, occupation, and sector of employment among adult males and females. Using data from the 10 percent population sample of the 2000 Population and Housing Census of Mexico and the empirical strategy that Bertrand, Luttmer, and Mullainathan (2000) propose, which allows us to take into account the role of municipality and language group fixed effects, we confirm empirically that social network effects play an important role in the economic decisions of indigenous people, especially in rural areas. Our analysis also provides evidence that better access to basic services such as water and electricity increases the size and strength of network effects in rural areas.     

Paradoxes of internationalisation of the Anglophone problem in Cameroon

Historically it is not strange that the Anglophone elites in Cameroon took their case to the international community, since this was a strategy that they employed during the British colonial period. A number of petitions and constant visits were made to the United Nations (UN) by Anglophone elites concerning British neglect of their territory. These petitions were made in the form of presentations before the United Nations in New York or whenever there was a visiting UN mission to the trust territory. Nonetheless, since the early 1990s, the pattern of petitions has changed drastically. Petitions against the new state are different from those earlier petitions against colonialism. The aim of the petitions against the new state has been to draw the attention of the UN and the international community to the injustices inflicted upon minority English-speaking Cameroonians by the ruling government. The Anglophone elites believe that, by making their plight known to the international community, the latter might intervene to restore the statehood of Southern Cameroons.     

Microcredit and gender empowerment: policy implications for sustainable agricultural development in Eritrea

Sustainable agricultural development requires capital investment. However, farmers in Africa are constrained by inadequate access to microcredit. Therefore, this article examines the extent to which gender influences access to microcredit. The empirical results showed that women are less likely to be able to access microcredit, compared to men. The study also found that separate sets of factors including assets endowment, socio-economic, institutional, and technological factors significantly affected women’s and men’s access to microcredit. The article suggests that to promote sustainable agricultural development, gender differential should be critically considered in designing microcredit schemes that target farmers in Africa.     

Perception of Pay Equity in Public Universities in Ghana: Effect on Individual Performance and Work Behavior

Equity theory proposes that individuals perceiving inequity seek to restore equity through appropriate behavior. This research aimed to study the relationship between perceived pay equity and individual job performance among lecturers in public universities in Ghana. Using a survey of 313 lecturers, we found that employees’ perception of equity in the pay system is a significant factor in determining their job performance. Therefore, we recommend that managers attend to equity in the design and implementation of pay systems. Moreover, issues relating to the reward system should be carefully communicated to employees in order to prevent unnecessary perceptions of inequity.     

Comparative Islamist Perspectives on the Politics of Energy in the Middle East and Beyond

The article will describe the general Islamic approach on energy based on the Sunnah of Prophet Muhammad, as well as the writings of prominent Muslim thinkers. Then it will examine and compare the energy perspectives of four Islamist groups: Hizballah, Hizb ut-Tahrir, the Muslim Brotherhood, and Al Qaeda. It will be argued that Islamist groups have attempted to achieve their external energy objectives by either using violence or exercising political blackmail against their opponents. Moreover, Islamists have developed globalized, glocalized, or localized “scale of engagement,” depending on the targeted audience. Finally, the article will examine the security implications stemming from Islamists’ interest in energy issues.     

Therefore,Is Bureaucracy Dead? Making a Case for Complementarity of Paradigms in Public Administrative Thinking and Discourse

Public Administration has gone through conceptual development to inject renaissance and public value creation. The literature provides a battleground of ideas between bureaucracy, new public management and post NPM with the latter ones chastising bureaucracy. The new developments should be seen as perfecting and correcting some of the extremes of bureaucracy but cannot replace it entirely. Owing to the broad nature of the public sector coupled with complex goals, agencies and mandates; this paper argues for a synergistic relationship and harmonization of the principles espoused by each paradigm; because each may be applicable in specific context, sector and periods.
