Elephants or Excrement? Comparison of the Power of Two Survey Methods for Elephants in West African Savanna
Emmanuel M. Hema, R. F. W. Barnes, Wendengoudi Guenda
Statistical power is the key issue when evaluating wildlife trends. Wildlife managers in West Africa lack light aeroplanes and must often estimate wildlife trends on foot, either by counting the animals themselves or by counting their dung. We compared direct ground counts of elephants and dung counts in two consecutive years in Nazinga Game R(...)

Comment repérer les personnes âgées en incapacités fonctionnelles et vivant à domicile en Afrique Subsaharienne ? L'utilisation du PRISMA7 à Bobo-Dioulasso (Burkina Faso)
Abdramane Berthé, Lalla Berthé-Sanou, Blahima Konaté, Hervé Hien, Fatoumata Tou, Serge M. A. SOMDA, Maxime Drabo, Fatoumata Badini‐Kinda, Jean Macq
Contexte: La littérature scientifique prévoit une importante augmentation des personnes âgées en incapacités/dépendances fonctionnelles en Afrique. Il est nécessaire que dès maintenant l'Afrique commence à s'organiser pour anticiper sa gestion de cette augmentation. Objectif: Repérer les personnes âgées en incapacités fonctionnelles et vivant(...)

Acceptability of HIV Vaccine Clinical Trials in Burkina Faso: Stakeholders’ Perceptions
Abdramane Berthé, Isidore Traoré, Lalla Berthé-Sanou, Josiane Somé, Souleymane Salouka, Jérémi Rouamba, Philippe Mayaud, Nicolas Nagot, Nicolas Méda, Kassoum Koné, Toumani Sidibé
Introduction: The ideal response to HIV would be the discovery of an effective vaccine. Evaluation of the benefit/risk balance of this vaccine must include Africa, where the majority of HIV infections are observed. This study was designed to identify the perceptions and the medium-term acceptability of a potential vaccine trial in Ouagadougou(...)

Partage de l’information sur le statut sérologique VIH positif : facteurs associés et conséquences pour les personnes vivant avec le VIH/sida au Burkina Faso

Abstract
Disclosure of HIV-serostatus remains a way to avoid sexual transmission of HIV because it allows partners to take the necessary protective measures, e.g. use of condoms. Disclosure is nevertheless difficult due to the discrimination associated with HIV. The objective of this study was to analyze factors leading to self-disclosure of(...)

The ambivalence of stigma and the double-edged sword of HIV/AIDS intervention in Burkina Faso
Quentin Gausset, Hanne Overgaard Mogensen, Wambi Maurice Evariste Yaméogo, Abdramane Berthé, Blahima Konaté
Cet article analyse les causes de la stigmatisation du VIH au Burkina Faso, telles que perçues par les personnes vivant avec le VIH/SIDA (PVP) et les personnes travaillant dans les organisations communautaires (CBO) liées au SIDA. La stigmatisation reste un problème pressant dans la lutte contre le VIH/SIDA en Afrique subsaharienne. L’article(...)

Distribution of savannah elephants (Loxodonta africana africana Blumenbach 1797) within Nazinga game ranch, Southern Burkina Faso
Emmanuel M. Hema, R. F. W. Barnes, Wendengoudi Guenda
We tested the hypothesis that elephant distribution inside the Nazinga Game Ranch (Southern Burkina Faso) during the wet season is influenced by villages outside, while in the dry season elephants are restricted only by water. Occupancy was evaluated by recording elephant dung-piles on 54 line transects in each of three seasons: wet 2006, dry(...)

[Community involvement in tuberculosis care in three rural health districts of Burkina Faso].
Maxime Drabo, Roger Zerbo, Abdramane Berthé, Laurent Ouedrago, Salif Konfe, Etienne Mugisho, Bruno Dujardin, Jean Macq
OBJECTIVE: Develop, implement and evaluate a form of community involvement in TB care in three rural health districts (DS). METHODS: Profiles of community representatives were identified within the therapeutic itineraries of TB patients (PATB). Community contributions have been made in a specific context via a committee of community resource p(...)

Rare earth and trace element geochemistry of termite mounds in central and northeastern Namibia: Mechanisms for micro-nutrient accumulation
Aboubakar Sako, Anthony J. Mills & Alakendra N. Roychoudhury
Rare earth element (REE) and trace element concentrations of ten termite mounds and adjacent topsoil from central and northeastern Namibia were used to investigate the processes underlying the alteration of soil chemical and physical properties by termites (Macrotermes spp.). Accumulation of micro-nutrients in the mounds was of particular inte(...)

Comparison of two dung count methods for estimating elephant numbers at Kakum Conservation Area in southern Ghana
Yaw Agyeman Boafo, Mildred Manford, R. F. W. Barnes, Emmanuel M. Hema, Emmanuel Danquah, Awo Nandjui, Umaru-Farouk Dubiure
The efficiency of meandering transects—in terms of accuracy, precision and effort required for estimating elephant abundance—was evaluated in the Kakum Conservation Area in Ghana. Four consecutive elephant dung surveys were carried out between February 2000 and February 2002 using meandering transects. The resulting dung density estimates were(...)

Communiquer avec son entourage sur son traitement aide-t-il les femmes impliquées dans le commerce du sexe à l'observer?

Il existe peu de données relatives aux difficultés d’observance d’un traitement chez les femmes impliquées dans le commerce du sexe (FISC). Nous avons étudié la capacité de ces femmes à prendre un traitement prolongé, en évaluant l’impact de la communication avec l’entourage sur l’observance d’un tel traitement. Les données ont été collectées(...)

Adsorption and surface complexation modeling of palladium, rhodium and platinum in surficial semi-arid soils and sediment
Aboubakar Sako, Lidia Lopes & Alakendra N. Roychoudhury
Sorption isotherms, time-dependent adsorption and surface complexation modeling studies were used to investigate the post-depositional mobility of three of the platinum group-elements (Pd, Rh, and Pt) in semi-arid soil and sediment samples with varying surface properties. The acidity constants (Log Ka1 and Log Ka2), optimized from batch titrat(...)

Comprendre et atteindre les jeunes travailleuses du sexe clandestines du Burkina Faso pour une meilleure riposte au VIH

In 1998, researchers in Burkina Faso enrolled 300 women more or less involved in commercial sex work in an open cohort to determine whether adequate management of their sexually transmitted infections and exposure to well-designed, well-delivered, and plentiful communication for behaviour change (CBC) might reduce their vulnerability to HIV.

CONTEXT AND OBJECTIVES: Since 1998, researchers in Burkina Faso have enrolled about 760 vulnerable women (sex workers, bar waitresses, pedlars, students, etc.) in an open cohort (the Yerelon cohort) to determine whether adequate management of sexually transmissible infection and exposure to well-designed, well-delivered, and plentiful communic(...)

Stable Oxygen and Carbon Isotopic Compositions of Lates stappersii Otoliths from Lake Tanganyika, East Africa
Aboubakar Sako, Kenneth G. MacLeod, and Catherine M. O’Reilly
In this study, we measured growth trends in oxygen and carbon isotopic ratios in whole sagittal otoliths from three adult centropomid fish (Lates stappersii) from each of three sub-basins of Lake Tanganyika, East Africa. Sampling density was 20 to 50 samples per otolith. Both d 18C values increase with age. The d 18O and d 13O data suggest tha(...)
