Argemone mexicana decoction versus artesunate-amodiaquine for the management of malaria in Mali: policy and public-health implications.
Get PDFA classic way of delaying drug resistance is to use an alternative when possible. We tested the malaria treatment Argemone mexicana decoction (AM), a validated self-prepared traditional medicine made with one widely available plant and safe across wide dose variations. In an attempt to reflect the real situation in the home-based management of malaria in a remote Malian village, 301 patients with presumed uncomplicated malaria (median age 5 years) were randomly assigned to receive AM or artesunate-amodiaquine [artemisinin combination therapy (ACT)] as first-line treatment. Both treatments were well tolerated. Over 28 days, second-line treatment was not required for 89% (95% CI 84.1-93.2) of patients on AM, versus 95% (95% CI 88.8-98.3) on ACT. Deterioration to severe malaria was 1.9% in both groups in children aged 5 years) and 0% had coma/convulsions. AM, now government-approved in Mali, could be tested as a first-line complement to standard modern drugs in high-transmission areas, in order to reduce the drug pressure for development of resistance to ACT, in the management of malaria. In view of the low rate of severe malaria and good tolerability, AM may also constitute a first-aid treatment when access to other antimalarials is delayed
АФРИКАНСКАЯ КОНТИНЕНТАЛЬНАЯ ЗОНА СВОБОДНОЙ ТОРГОВЛИ (AFCFTA): СОЦИАЛЬНО-ЭКОНОМИЧЕСКОЕ И ПОЛИТИЧЕСКОЕ ВОЗДЕЙСТВИЕ НА СТРАНЫ АФРИКИ К ЮГУ ОТ САХАРЫ И ЕЕ ПЕРСПЕКТИВЫ
No full textThe article discusses the socio-economic, political impacts and future prospects of the African continental free trade zone. In the context of the global economic crisis, (AfCFTA) is one of the most significant projects within the framework of the African Agenda 2063 of the African Union (AU). This project was approved by the African Union Summit in 2018 and is considered an urgent initiative; its immediate implementation will lead to quick results, affect the socio-econom- ic development of African countries in general and especially for sub-Saharan Africa, provide more confidence to Africans and strengthen their commitment to achievements of the goal of Agenda 2063В статье рассмотрено социально-экономическое и политическое воздействие Африканской континентальной зоны свободной торговли на развитие стран Африки, а так же ее дальнейшие перспективы. В условиях глобального экономического кризиса, AfCFTA является одним из наиболее знаковых проектов Африканского Союза (АС) в рамках Африканской повестки дня до 2063 года. Этот проект был одобрен Саммитом Африканского Союза в 2018 году и считается неотложной инициативой, немедленное осуществление которой, приведет к быстрым результатам по улучшению социально-экономического развития стран Африки в общем и особенно стран, расположенных к югу от Сахары
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
prise en charge des urgences médicales au service d’accueil des urgences du centre hospitalier universitaire du point g.
No full textNous avons mené une étude prospective, observatiçonnelle et analytique basée sur trois mois allant du 1er juin au 31 aout 2018 au service d’accueil des urgences du CHU du Point G.
L’objectif général était d’évaluer la prise en charge des patients admis pour une urgence selon deux modalités (observation et hospitalisation).
Un échantillon était exhausif de l’ensemble des patients admis pour une urgence médicale au service d’accueil des urgences du Point G.
Au terme de notre étude, la qualité de la prise en charge est d’un niveau satisfaisant ou acceptable et cela par rapport aux normes et recommandations de la prise en charge des urgences médicales. Cela a permis d’obtenir un taux de transfert dans les services spécialités de 65,3% et un taux de sortie de 20,7%, un peu supérieur à celui de Sissoko M.
Les taux de décès sont similaires à celui de Sissoko.

Security Challenges and Migration in the Central Africa
No full textRelevance. In modern society, migration issues are closely related to security. The dynamics of the migration crisis in the context of Central African countries reflects civil wars, political and economic instability, hunger, massacres, impoverishment, and in addition to these, the phenomenon of terrorist threats has appeared. Purpose. The purpose of this article is to highlight situations with internal migration, aspects of the geopolitics of insecurity, threats, and security restrictions. The authors also analyze the link between security and migration. Objectives. Obtain more information on the properties of the compared phenomena and examine the direct and indirect relationship between migration and security in Central Africa. Methodology. To find out the reasons for the existing difficulties, set goals, develop methods and options for eliminating problems, a system analysis was used. And the authors used the method of comparative analysis to obtain added information about the properties of the compared phenomena, about their direct and indirect relationships and, about the general trend of their functioning and development. Results. According to researchers, in recent years, the relationship between migration and security has been of different nature. We can consider the problem of the security of African communities, societies and states affected by various problems of migration flows, and we can also consider the security aspect of African migrants in Central African countries. Conclusions. The African continent has now fully entered economic globalization and the international community, and it would be inevitable to question this statement in the name of preserving political, economic difficulties, security, migration, and refugees. The AU is in fact moving towards greater liberalization of intra-African movement, in a critical spirit of the European approach. The increasingly growing intra-African migratory movements are mainly and very often regional.Актуальность. В современном обществе вопросы миграции тесно связаны с безопасностью. Динамика миграционного кризиса в контексте стран Центральной Африки отражает гражданские войны, политическую и экономическую нестабильность, голод, массовые убийства, обнищание, в дополнение к этому возник феномен террористических угроз. Цель этой статьи - осветить ситуацию с внутренней миграцией, аспекты геополитики незащищенности, угрозы и ограничения безопасности. Авторы также анализируют связь между безопасностью и миграцией. Задачи: получить дополнительную информацию о свойствах сравниваемых явлений и изучить прямую и косвенную связь между миграцией и безопасностью в Центральной Африке. Методология. Для выяснения причин имеющихся трудностей, постановки целей, разработки методов и вариантов устранения проблем был использован системный анализ. Также авторы использовали метод сравнительного анализа, чтобы получить дополнительную информацию о свойствах сравниваемых явлений, об их прямых и косвенных отношениях, и также об общей тенденции их функционирования и развития. Результаты. По мнению исследователей, за последние годы связь между миграцией и безопасностью имеет разные характеры. Авторы рассматривают проблему безопасности африканских общностей, обществ и государств, затрагиваемых разными проблемами миграционных потоков, также аспект безопасности африканских мигрантов в странах Центральной Африки. Выводы. Африканский континент теперь полностью вступил в экономическую глобализацию и международное сообщество, и было бы неизбежно подвергнуть сомнению это заявление во имя сохранения политических, экономических трудностей, безопасности, миграции и беженцев. Фактически, АС движется к большей либерализации внутриафриканского движения в критическом духе европейского подхода. Все более растущие внутриафриканские миграционные потоки носят в основном и очень часто региональный характер
