The main objective of Zika transmission studies is to work out the simplest approach to scale back human mortality and morbidity caused by the disease. Therefore, it is essential to spot the relative importance of the various factors contributing to the transmission and prevalence of the disease. Many mathematical models have been formulated incorporating vector-to-human transmission or human-to-human transmission. However, they do not take into consideration the mixture of both sorts of transmission. It raises the question of the impact of (...) both sorts of transmission on the disease dynamics. We develop a mathematical model of Zika with the vertical transmission in the vector population and human-to-human transmission to answer this question. It includes the immature phase of mosquitoes, adult mosquitoes, and human hosts. Results show that neglecting sexual transmission results in an understatement of the proportion of the infected population. Furthermore, it reduces the speed of disease spreading. On the other hand, vertical transmission in mosquitoes has a negligible effect on the dynamics of disease spread. We perform a sensitivity analysis of the reproductive number R 0 to raise to understand the parameters driving the dynamics of the disease. It appears that the most sensitive parameters in decreasing order are as follows: the adult mosquito death rate, the sting rate, the transmission probability of mosquito to human, and, therefore, the transmission probability of human to mosquito. Furthermore, the proportion at the equilibrium of infected humans is extremely sensitive to the transition rate from the immature vector stage to the adult stage, the human-to-human transmission rate, and, therefore, the human recovery rate. These results confirm that control policies targeting the vector population and, therefore, the recovery rate of people are pretty effective solutions. To validate the model and estimate the important parameters of the model and the prediction of the disease, we consider the real cases in Colombia from 2016. In a series of graphic maps, we presented the comparative study to estimate the disease scenarios and to predict the time limit of the epidemic control measure. (shrink)

A travers la vingtaine de textes qui composent cet ouvrage, portant sur des savoirs et des pratiques de l'Afrique noire, l'auteur fonde son analyse sur l'hypothèse suivante : un invariant, plus significatif que tous les autres, occupe le coeur de la pensée africaine. Ce signifié ultime, c'est l'homme. Penser l'humain : la part africaine est une investigation philosophique sur des objets aussi variés que les mythes et les cosmogonies ; la conception et l'organisation de l'espace-temps ; la nature et la (...) fonction du savoir ; l'idéologie et le pouvoir ; le sacré et le profane ; l'idée de nombre et les spéculations sur ses usages. La recherche d'une unité aux discours portant sur ces différents objets trouve sa justification dans un avant-propos intitulé "La part africaine", formulation d'une problématique dont l'auteur s'emploie à dissiper les ambiguïtés et les équivoques pour mieux en souligner l'intérêt. Une manière de rappeler que si la réflexion sur l'homme et sa place dans l'univers peut être considérée comme un trait commun à tous les hommes, de toutes les cultures, cet universel s'incarne dans des profils que sont ses différentes manifestations dans le particulier. Dire de manière quasi obsessionnelle, au détriment d'autres approches du réel, que sans l'homme il n'y a pas de signification du monde, constitue ce qu'Abdoulaye Elimane Kane croit être le fond de la pensée africaine.

Le vécu dont je tire ce récit est mon expérience d'homme vivant avec une maladie chronique, l'asthme, dont les périodes alternées, plus ou moins longues, de crise et de rémission me donnèrent envie d'extrapoler sur le thème plus large du plaisir et de la douleur, retenant déjà comme titre provisoire de mon ouvrage Le plaisir et l'ennui, ces deux termes visant une extension de l'analyse au-delà des seules questions de santé et de maladie, incluant par conséquent, leurs équivalents et synonymes (...) dans la vie individuelle et collective. Entre-temps, mes enfants qui n'ont connu que deux de leurs grands-parents, sur le tard, et presque rien de la vie au Fouta alors que nos références familiales et nos évocations quotidiennes en sont remplies ; qui m'ont vu entrer dans la vie active et m'engager politiquement sans en comprendre toujours les tenants et les aboutissants, revinrent plusieurs fois à la charge pour me suggérer d'écrire sur la famille, sur ma petite expérience d'enseignant et d'homme politique, sur les hommes et les femmes qui m'ont marqué et, surtout, sur la place que j'accorde à l'amitié, à la fraternité et à la solidarité, trois notions qu'ils m'ont entendu évoquer souvent et qui, à ce qu'il leur semblait, importent, aujourd'hui, plus aux yeux des jeunes qu'à ceux des adultes.

Les débats menés autour de l’État africain, ces trente dernières années, ont reflété les grandes idées qui ont agité le monde contemporain, mais ils sont, dans l’ensemble, restés muets sur des questions soulevées au cours des deux décennies des Nations Unies pour la femme. Or une approche de genre des questions du politique s’avère indispensable sur bien des plans. Elle aide désormais à mieux saisir la manière dont l’inégalité entre les sexes est instituée, prolongée, voire renforcée au cœur du politique. (...) Cet article vise à montrer l’importance des travaux sur le genre, l’État et le politique et la logique dont ils procèdent. Il vise également à faire comprendre en quoi consiste l’interrogation sur le sexe de l’État en Afrique, sur la dimension masculine et patriarcale de l’État et son impact sur les politiques, sur les femmes et sur les rapports et les rôles sociaux des sexes. On ne saurait tendre vers les objectifs d’égalité dans le développement en Afrique sans reconsidérer le sexe de l’État et de ses politiques. (shrink)

Quelle est la situation actuelle des mutilations sexuelles féminines (M.G.F.), en Afrique, après vingt ans de controverses? On estime à environ 115 millions le nombre de femmes qui dans le monde ont subi des mutilations génitales : clitoridectomie, excision ou infibulation (Rapport Hosken,1993). L'immense majorité d'entre elles vivent en Afrique où les mutilations génitales continuent d'être pratiquées au nom de traditions culturelles et religieuses. Ces pratiques ont lieu à tout âge...

This chapter attempts to further the understanding of Sahelo‐Sudanic systems of slavery via enquiries into the daily life of slaves. This work is based on the memories of elders in certain villages within the zone of the ancient state of Kaarta and the buffer zone between it and the state of Segou, an area corresponding to the modern Malian administrative Cercles of Kolokani and Banamba. Temporally, the focus is on the period directly before the colonial era. In particular, the mode (...) of acquisition of slaves and the different types of local slavery are considered. (shrink)

Developing countries face numerous barriers to conducting effective and efficient ethics reviews of international collaborative research. In addition to potentially overlooking important scientific and ethical considerations, inadequate or insufficiently trained ethics committees may insist on unwarranted changes to protocols that can impair a study's scientific or ethical validity. Moreover, poorly functioning review systems can impose substantial delays on the commencement of research, which needlessly undermine the development of new interventions for urgent medical needs. In response to these concerns, the Drugs (...) for Neglected Diseases Initiative, an independent nonprofit organization founded by a coalition of public sector and international organizations, developed a mechanism to facilitate more effective and efficient host country ethics review for a study of the use of fexinidazole for the treatment of late stage African Trypanosomiasis. The project involved the implementation of a novel ‘pre-review’ process of ethical oversight, conducted by an ad hoc committee of ethics committee representatives from African and European countries, in collaboration with internationally recognized scientific experts. This article examines the process and outcomes of this collaborative process. (shrink)

Malian farmers’ traditional system for managing seed of sorghum, an indigenous crop of vital importance for food security and survival, can be conceptualized as a commons. Although this system maintains a wide range of varieties and helps ensure access to seed, its ability to create and widely disseminate new varieties to meet evolving opportunities and challenges is limited. A network of farmer groups, public breeding programs, and development organizations collaborating in decentralized creation and dissemination of sorghum varieties in Mali is (...) examined regarding (1) how the network developed and what activities it conducts; (2) the resulting varietal diversity, varietal performance and organizational models; and (3) the elements of the traditional seed system that were maintained, strengthened or transformed. A single-case study approach was used that relies on published literature, official catalogues of released varieties and a database of farmer seed-cooperative requests for foundation seed. The functioning of the network and its varietal-, seed-, and organizational- outcomes are documented and the elements of the traditional sorghum seed system that are maintained or strengthened are analyzed. The evolution of the network’s reliance on commoning as a social process and its strengthening of core Seed Commons features are discussed with a view to the network’s contributions to targeted development outcomes and potential replicability. The case demonstrates how creating a framework for collaboration, enabling actors and organizations to take on collective responsibility while maintaining distributed decision-making at local level, opens opportunities for transforming farming- and food-systems towards sustainability and resilience.

Attitudes toward sow husbandry differ between citizens and conventional pig farmers. Research showed that moral values could only predict the judgment of people in case of culling healthy animals in the course of a disease epidemic to a certain extent. Therefore, we hypothesized that attitudes of citizens and pig farmers cannot be predicted one-on-one by moral values. Furthermore, we were interested in getting insight in whether moral values can be useful in bridging the gap between attitudes toward sow husbandry of (...) citizens and pig farmers. Based on a questionnaire, it was found that pig farmers and citizens, when considered as one group, shared the valuation of most moral values. However, when studying the four clusters of citizens with different attitudes toward sow husbandry, determined in a previous study, a variation in valuation of the moral values between the clusters of citizens and farmers came to the fore. This means that moral values are interpreted differently by groups of people when forming attitudes toward sow husbandry. The results of our study give an indication of which moral values are weighed differently between clusters of citizens and pig farmers. This information can be useful in future research on attitudes toward animal husbandry in order to understand why attitudes differ between groups of people. Besides, our results can be useful for the pig sector and citizens to learn to understand each other’s attitudes. With this understanding it is possible to invest in a husbandry system that can build on societal support. (shrink)

Summary: Because this book has something of the storytelling of cheerful meetings, von Foerster is made more accessible to the novice; however, it does not lose any of its intellectual sharpness. Henri Atlan and Edgar Morin, in particular, greatly influenced by von Foerster and quite famous in French-speaking countries, give a helping hand to those who wish to explore their work further from the perspective of von Foerster's vision and thoughts. And Atlan and Morin take also the credit for the (...) fact that von Foerster has become better known in the French-speaking community. Let us a hope the book will contribute to the further spread of von Foerster's ideas. (shrink)

In an effort to restrict seed piracy in the global agricultural market, Monsanto intends to implement some form of genetic use restriction technology. Regarding such intentions, many activist groups adamantly contend that Monsanto will be acting immorally if GURTs, specifically Terminator Technology, are implemented in the global agricultural market. They argue that the potential implementation of TT is immoral because it threatens to infringe upon the rights of resource-poor farmers by denying them the ability to save the seed derived from (...) their harvests. While there may be ways that the implementation of TT can be construed as wrong, I narrowly argue that Monsanto will not be wrongfully infringing upon the basic rights of resource-poor farmers if it actually implements TT. Moreover, as long as Monsanto takes the appropriate measures to minimize the possible negative effects that TT may have on resource-poor farmers, and allows these farmers to make an autonomous choice to use seed that contains this technology, Monsanto's possible implementation of TT cannot be accurately considered to instantiate an immoral violation of basic rights.

This paper argues that the MBA, probably the most successful academic program of the last 50 years, negatively affects the theory and practice of management with regard to ethics through its pedagogy, structure, and its underlying epistemic assumptions. In particular I seek to demonstrate how the syllabus, the pedagogy and the epistemological assumptions of MBA programs together make managers/leaders unable and unwilling to deal with ethics. I also argue that while the what and the how play a very important role, (...) it was only the emergence of a radical philosophical underpinning that has put management education on a negative trajectory. The paper thus examines MBA education from a meta-level perspective, connecting the pedagogical model with epistemological beliefs. (shrink)

Sows housed in stalls are kept insuch extreme confinement that they are unableto turn around. In some sectors of the porkindustry, sows are subjected to this degree ofconfinement for almost their entire lives(apart from the brief periods associated withmating). While individual confinement isrecognized by farmers and animal welfarecommunity organizations alike, as a valuabletool in sow husbandry (to mitigate againstaggression), what remains questionable from ananimal welfare point of view is the necessityto confine sows in such small spaces.In 2001, the Australian Journal (...) ofAgricultural Research published a reviewarticle on the science associated with the useof the sow stall, and claimed that ``noscientific evidence to support therecommendation in the Code of Practice advisingagainst housing of sows in stalls followed byhousing in crates'''' (Barnett et al., 2001, p. 21).If all the available scientific publications onthe animal welfare implications of sow stallsare consulted (many of which did not feature inthe above review), then one will indeed findscientific evidence to support recommendationsagainst the housing of sows in stalls. Becausethere is science on both sides of this policydivide, the argument to defend the use of sowstalls, therefore, is not one of science vspublic opinion, but one of ethics. (shrink)

The issues of tithes and seed sowing have taken a central focus in contemporary Christianity in Nigeria among the preachers. Many a time, it is assumed that tithes and seed sowing are requirements for salvation, prosperity and total well-being of the members. Making many to believe that Christianity is a money-venture business one can succeed if he knows how to hoodwink the gullible. Many have been deceived that by parting with a substantial amount of money in the name of sowing (...) seed, their problems would be solved. Unfortunately, the person’s problem may remain the same or even be compounded. This paper evaluates the activities, attitude and their inordinate ambitions. It examines the impact of tithe and seed sowing on Christianity in Nigeria. The research method adopted for this work is the qualitative phenomenological method. The paper observed that the value of tithe and seed sowing has changed from what is prescribed in the bible to what is preached on the pulpits. The study recommends among other things, that these preachers should preach the gospel with decorum and as it were in the bible so that its influence on Nigerians will bring about a reduction in crime, corruption and other immoral activities in Nigeria. Contribution: The article is focused on the issues of tithes and seed sowing. It underscores the fact that the message of tithe and seed sowing has become a means of siphoning members and enriching the preachers. It further reveals its negative and positive impacts such as, the promotion of corruption and fraud in the church and society, contribution to the decline of morality in the church and the society, increasing crime rate and increasing poverty rate in Nigeria among others.

Although a growing body of research has shown the positive impact of ethical leadership on workplace deviance, questions remain as to whether its benefits are consistent across all situations. In this investigation, we explore an important boundary condition of ethical leadership by exploring how employees’ moral awareness may lessen the need for ethical leadership. Drawing on substitutes for leadership theory, we suggest that when individuals already possess a heightened level of moral awareness, ethical leadership’s role in reducing deviant actions may (...) be reduced. However, when individuals lack this strong moral disposition, ethical leadership may be instrumental in inspiring them to reduce their deviant actions. To enhance the external validity and generalizability of our findings, the current research used two large field samples of working professionals in both Turkey and the USA. Results suggest that ethical leadership’s positive influence on workplace deviance is dependent upon the individual’s moral awareness—helpful for those employees whose moral awareness is low, but not high. Thus, our investigation helps to build theory around the contingencies of ethical leadership and the specific audience for whom it may be more influential. (shrink)
