The public sector of many African countries is notoriously corrupt; cultural inclinations and socialization processes largely have a tendency to lead public officials into actions that may amount to corrupt practices. Providing seven (7) key pointers for reflection, this study explores public sector corruption in African countries by examining the interplay between culturally acceptable norms and professional expectations of public officials. The public official, by these two unparalleled expectations, tends to walk on a tight rope which often results in ethical dilemma and conflict of interest. The study adopts Riggs' prismatic‐sala model and uses the case of Ghana and traditional proverbs to explain the cultural context within which Ghanaian public official ought to operate. How can one combine these cultural expectations with professionalism? To what extent does the ‘collectivity culture’, ‘culture of gift giving and acceptance’, ‘extended family system’, ‘ethnic loyalty’ and ‘unfettered respect of the aged’ downplay professional bureaucratic and ethical principles?

This article reports on a study that examined the saving behaviour of farmers in southern Ghana, using a sample of 100 citrus farmers. Probit and Tobit models were used in determining the factors that influence farmers’ saving behaviours and amount of saved, respectively. The empirical findings showed that age, household size, dependency, marital status, distance to financial institution, transport cost and congestion exerted significant negative impact on farmers’ saving behaviours. On the other hand, income, education, and gender tended to promote good saving behaviour. The article concludes that heterogeneity of factors ranging from socio-economic, household assets, and institutional factors greatly stimulate farmers’ saving behaviour.  相似文献

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.  相似文献

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.  相似文献

Improving access to water and sanitation facilities has been a priority on the international development agenda. Halving the number of those who do not have access to sanitation facilities is an MDG target. This study assessed the toilet conditions in an urban slum in Ghana. Many felt that the sanitary conditions were deplorable; they were unsatisfied with having to walk over half a kilometre before using a toilet. Government efforts to improve hygiene and address sanitation problems need to take into account financial, religious, and other factors that promote the supply and maintenance of appropriate toilet facilities and services in urban communities.

Toilettes n'est pas un mot tabou : à deux doigts d'atteindre les OMD en matière d'assainissement ?

L'amélioration de l'accès à l'eau et aux installations sanitaires a été une priorité de l'ordre du jour international en matière de développement. La réduction de moitié du nombre de personnes qui n'ont pas accès à des installations d'assainissement est un OMD. Cette étude a évalué les conditions sur le plan des toilettes dans un bidonville urbain du Ghana. De nombreuses personnes estimaient que les conditions d'assainissement y étaient déplorables; elles n'étaient pas satisfaites de devoir parcourir plus d'un demi-kilomètre pour pouvoir utiliser des toilettes. Les efforts fournis par les pouvoirs publics pour améliorer l'hygiène et résoudre les problèmes d'assainissement doivent tenir compte des facteurs financiers, religieux et autres qui favorisent la fourniture et l'entretien d'installations et de services de toilettes dans les communautés urbaines.

Excusado no es una mala palabra: ¿se está próximo a cumplir con los odm en el área de saneamiento?

La ampliación del acceso al agua potable y al saneamiento ha sido una prioridad del desarrollo internacional. Una de las metas de los odm es reducir a la mitad el número de personas que actualmente carecen de acceso al saneamiento. El presente artículo valora las condiciones en que se encuentran los excusados en un barrio pobre de Ghana. Muchos de quienes residen allí consideran que las condiciones de saneamiento son deplorables, manifestando su desacuerdo con tener que caminar más de medio kilómetro para hacer uso del excusado. Los esfuerzos realizados por el gobierno para mejorar la higiene y enfrentar los problemas de saneamiento, deberán tomar en cuenta tanto los factores financieros como los religiosos u otros que promuevan la oferta y el mantenimiento de excusados, así como la posibilidad de otros servicios de saneamiento en las comunidades urbanas.

Banheiro não é uma palavrão: estamos prestes a cumprir os ODMs para saneamento?

Melhorar o acesso a redes de abastecimento de água e saneamento tem sido uma prioridade na agenda de desenvolvimento internacional. Reduzir pela metade o número de pessoas que não têm acesso a redes de saneamento faz parte dos Objetivos de Desenvolvimento do Milênio (ODMs). Este estudo avaliou as condições de banheiros em uma favela na zona urbana de Gana. Muitos sentiam que as condições de saneamento eram deploráveis e estavam insatisfeitos em ter de caminhar mais de meio quilômetro para usar um banheiro. Esforços do governo para melhorar a higiene e abordar os problemas de saneamento precisam levar em conta fatores financeiros, religiosos, além de outros, que promovam o fornecimento e manutenção de instalações de banheiros e serviços adequados nas comunidades urbanas.  相似文献

During both World Wars, one of the most powerful weapons Belgian citizens possessed in resisting German occupation of their country was the gathering of intelligence on the enemy for the allied armies. But Belgian's first and second secret wars were different in several respects, one of the most important being the relationship between the Belgian secret services in exile and their British counterparts. If the First World War was essentially a story of bitter concurrency between them, the Second was mostly a tale of ‘jealous’ partnership. The relations with the intelligence networks in occupied Belgium formed a delicate but crucial issue, where money played an important role. This article explores these dynamics and how they affected the main mission of gathering intelligence on the Germans.  相似文献

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.  相似文献

Tribulus terrestris is a nutritional supplement highly debated regarding its physiological and actual effects on the organism. The main claimed effect is an increase of testosterone anabolic and androgenic action through the activation of endogenous testosterone production. Even if this biological pathway is not entirely proven, T. terrestris is regularly used by athletes. Recently, the analysis of two female urine samples by GC/C/IRMS (gas chromatography/combustion/isotope-ratio-mass-spectrometry) conclusively revealed the administration of exogenous testosterone or its precursors, even if the testosterone glucuronide/epitestosterone glucuronide (T/E) ratio and steroid marker concentrations were below the cut-off values defined by World Anti-Doping Agency (WADA). To argue against this adverse analytical finding, the athletes recognized having used T. terrestris in their diet. In order to test this hypothesis, two female volunteers ingested 500 mg of T. terrestris, three times a day and for two consecutive days. All spot urines were collected during 48 h after the first intake. The 13C/12C ratio of ketosteroids was determined by GC/C/IRMS, the T/E ratio and DHEA concentrations were measured by GC/MS and LH concentrations by radioimmunoassay. None of these parameters revealed a significant variation or increased above the WADA cut-off limits. Hence, the short-term treatment with T. terrestris showed no impact on the endogenous testosterone metabolism of the two subjects.  相似文献
