Factors Affecting E-Business Adoption by SMEs in Sub-Saharan Africa

2009

The use of information communication technologies (ICT) especially the Internet by small- and medium-sized enterprises (SMEs) is on the increase in many regions of the world, including Africa. Nevertheless, empirical evidence from Sub-Saharan Africa (SSA) regarding the factors that affect the adoption of e-business is scarce. In that regard, the main objective of this chapter is to fill the research gap with an exploratory study that is aimed at eliciting views from SMEs in Nigeria. This article made use of a theoretical framework encompassing organizational, external and technological contexts to deliberate the issue. A survey is conducted in three Nigerian cities and the findings of the s…

First morphogenetic analysis of parasite eggs from Schistosomiasis haematobium infected sub-Saharan migrants in Spain and proposal for a new standard…

2021

International audience; Schistosomiasis is a Neglected Tropical Disease caused by trematode species of the genus Schistosoma. Both, autochthonous and imported cases of urogenital schistosomiasis have been described in Europe. The present study focuses on eggs, considered pure S. haematobium by genetic characterisation (intergenic ITS region of the rDNA and cox1 mtDNA). A phenotypic characterisation of S. haematobium eggs was made by morphometric comparison with experimental populations of S. bovis and S. mansoni, to help in the diagnosis of S. haematobium populations infecting sub-Saharan migrants in Spain. Analyses were made by Computer Image Analysis System (CIAS) applied on the basis of …

The Education Production Function reviewed in the framework of Education For All in Sub-Saharan Africa: from theoretical and methodological bounds to…

2007

The Coleman report (1966) was the first of numerous researches exploring quality of learning determinants analysis. With the Education Production Function (EPF), economists have greatly contributed to the extension of this research domain. Actually, empirical works are leading the field with important methodological debates which have fuelled controversies (Hanushek, 2003; Krueger, 2003). Thus, methodological issues have particularly rallied researchers' interests on empirical estimations, while academic researches on the renewal of the theoretical framework have remained scarce despite obvious bounds. Without contesting the validity of miscellaneous estimation problems and the necessity of…

Global, regional, and national burden of chronic kidney disease, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017

2020

Abstract: Background Health system planning requires careful assessment of chronic kidney disease (CKD) epidemiology, but data for morbidity and mortality of this disease are scarce or non-existent in many countries. We estimated the global, regional, and national burden of CKD, as well as the burden of cardiovascular disease and gout attributable to impaired kidney function, for the Global Burden of Diseases, Injuries, and Risk Factors Study 2017. We use the term CKD to refer to the morbidity and mortality that can be directly attributed to all stages of CKD, and we use the term impaired kidney function to refer to the additional risk of CKD from cardiovascular disease and gout. Methods Th…

Unexpected vertical structure of the Saharan Air Layer and giant dust particles during AER-D

2018

The Saharan Air Layer (SAL) in the summertime eastern Atlantic is typically well mixed and 3–4 km deep, overlying the marine boundary layer (MBL). In this paper, we show experimental evidence that at times a very different structure can be observed. During the AERosol properties – Dust (AER-D) airborne campaign in August 2015, the typical structure described above was observed most of the time, and was associated with a moderate dust content yielding an aerosol optical depth (AOD) of 0.3–0.4 at 355 nm. In an intense event, however, an unprecedented vertical structure was observed close to the eastern boundary of the basin, displaying an uneven vertical distribution and a very …

Social Disparities in Education in Sub-Saharan African Countries

2007

In this paper we have two complementary objectives: the first is to describe the magnitude of social disparities that exist in the systems of education of sub-Saharan African countries; we focus on recent data but we also put these data in a time perspective. The second objective is to identify some of the factors that may explain these disparities and the impact of policies aimed at their reduction.

Du verbe instrumental dans la musique subsaharienne

2021

Sub-Saharan music results from the spoken language/instrumental language relation, directed by an oral culture. In this culture, these languages transmit ? beyond their singularities ? messages thanks to either a coded signal known by the linguistic community or previously defined among a group of individuals, or is used as a true meta-language copied on the articulated and usual language used every day. Here, an instrumental musical speech can then imitate and reproduce the tonal inflexions of the language to make its matter understandable. This fact is the natural result of a strong interaction and interrelation between the spoken language and the music as well as the conception that the …

Conflict management in the international context : analyzing the role of the United Nations in the Western Sahara conflict

2017

The United Nations is the most productive international organization in resolving international world conflicts. The UN uses different techniques and approaches to resolve international conflicts, including mediation. This study analyzes the process of mediation and international conflict management from the point of view of UN efforts in the Western Sahara conflict, which has been ongoing since 1975. This study specifically focuses on the UN’s role in resolving intercultural conflict in Western Sahara and the concrete steps it has taken, such as implementation of the cease-fire, the Settlement Plan and establishing the Mission for an independence referendum in Western Sahara (MINURSO). It …
