Contatti di popoli ed etnogenesi delle tribù nomadi sahariane
2006
The contribution focuses on the problem of mobility in the Roman world as a means of contact and collaboration. North Africa was in ancient times a land of cultural exchange, of passage of peoples and people. The research dwells on local identities, studies the origins of these peoples, discusses and tries to understand the ancient dynamics, which led them to clash and meet.

Evaluating diagnostic indicators of urogenital Schistosoma haematobium infection in young women: A cross sectional study in rural South Africa
2018
BackgroundUrine microscopy is the standard diagnostic method for urogenital S. haematobium infection. However, this may lead to under-diagnosis of urogenital schistosomiasis, as the disease may present itself with genital symptoms in the absence of ova in the urine. Currently there is no single reliable and affordable diagnostic method to diagnose the full spectrum of urogenital S. haematobium infection. In this study we explore the classic indicators in the diagnosis of urogenital S. haematobium infection, with focus on young women.MethodsIn a cross-sectional study of 1237 sexually active young women in rural South Africa, we assessed four diagnostic indicators of urogenital S. haematobium…
Balance with logic-measuring the performance and sustainable development efforts of an NPO in rural Ethiopia.
2021
The analysis of performance of Not-for-profit organisations (NPOs) is difficult because there are several objectives and perspectives to NPO performance and accountability, especially if considered sustainably and in long term. This suggests that performance analysis and measurement of NPOs might also involve multiple perspectives, such as in Balanced Scorecard (BSC) or in the Logical Framework (LF) models. This article is a case study of analysing the sustainable development and performance of an NPO in rural Ethiopia. We propose the Logic Balanced Scorecard (LBSC) model that combines elements of BSC and LF. This proposal was preliminarily used and tested in a five-year interventionist acc…
Mapping schistosoma haematobium for novel interventions against female genital schistosomiasis and associated HIV risk in kwazulu-natal, South Africa
2021
Abstract.Women with female genital schistosomiasis (FGS) have been found to have genital symptoms and a three-fold higher risk of HIV infection. Despite WHO recommendations, regular antischistosomal mass drug administration (MDA) has not yet been implemented in South Africa possibly because of the lack of updated epidemiological data. To provide data for future prevention efforts against FGS and HIV, this study explored Schistosoma haematobium prevalence in girls and young women and the effects of antischistosomal MDA, respectively. Urinary schistosomiasis and genital symptoms were investigated in 70 randomly selected secondary schools in three districts within KwaZulu-Natal and 18 primary …
La povertà rurale in Africa Sub-sahariana: il caso del Dipartimento della Lekie in Camerun
2021
Questo articolo mette in rilievo le caratteristiche della povertà rurale in Africa sub-sahariana in generale, e nel Dipartimento della Lekie in Camerun in particolare. Il suo interesse sta nel fatto che per meglio combattere la povertà, bisogna innanzitutto capire la sua vera natura e le sue particolari caratteristiche sul territorio d’intervento. Questo studio mira dunque a offrire alla comunità scientifica nonché a vari portatori d’interesse un quadro di riferimento per la definizione di politiche economiche efficaci contro la povertà sul territorio del Dipartimento della Lekie. L’indagine svolta sul cosiddetto territorio ha rilevato, tramite un’analisi descrittiva, che le popolazioni del…
Early Warning Systems for Food Security in West Africa: Evolution, Achievements and Challenges
2010
In West Africa, early warning systems (EWSs) for food security have been widely recognized to have contributed, in the last 20 years, to an improved ability to deal with famine emergencies. Nevertheless, despite the advancements in understanding of the environmental and socio-economic dynamics and despite the improved technologies, tackling food security remains a difficult task for decision makers as demonstrated by local food crises in many countries of the region. African Monsoon Multidisciplinary Analysis, while improving the understanding of the monsoon system, allowed us to better orient research challenges to provide EWS with improved products, effectively meeting the needs of end-us…
Smarter Teachers, Smarter Pupils? Some New Evidence from Sub-Saharan Africa
2017
Document de travail du BETA, n°2017-35. En ligne sur : http://www.beta-umr7522.fr/productions/publications/2017/2017-35.pdf; We study the effect of teacher subject knowledge on student achievement in mathematics and reading by using a dataset from six Sub-Saharan African countries. By using a difference-indifference between pupils' and teachers' scores in two skills, we are able to avoid potential endogeneity bias. In most estimations, we do not find a significant teacher knowledge effect in most countries. The main reason is teacher absenteeism and the need to focus on core knowledge. Indeed, more knowledgeable teachers improve student learning only if certain conditions are met. For insta…
Eclogites and garnet pyroxenites: Similarities and differences
2010
Eclogites and garnet pyroxenites are genetically linked to basaltic precursors. Traditionally garnet pyroxenites are linked to fractionation of basaltic Magmas Over a range of mantle pressures and more recently they have been implicated in the genesis of ocean islands. in contrast eclogites are linked to the subduction of slab basalt and gabbro precursors which may be hydrothermally altered. Recently this subduction paradigm has been questioned. We present mineralogical, trace element and O isotopic data for eclogites and garnet pyroxenites that reveal some similarities but also important chemical and isotopic differences that support a distinct provenance (i.e., age and process). Continent…
Developing Lower secondary education: a rural issue and challenge for sub-saharan Africa
2010
The ongoing progresses of coverage of primary education in Sub-Saharan African Countries are inevitably to impact lower secondary education in a significant manner. Beyond the need for all countries to identify a global policy to deal with the problem, it is important to understand that expansion of coverage of lower secondary education will concern rural populations since coverage is generally already relatively high in cities while it is lagging noticeably in rural settings; many schools will need to be built and operate in a near future. A basic characteristic of rural schools is that most of them enroll only a limited number of students and, in current circumstances tend to cost signifi…
