Resolución de "pequeños" conflictos en zonas de "grandes" conflictos. Una aproximación desde la antropología a las nociones endógenas de paz en Casamance (Senegal)

[ES] A menudo, las grandes instituciones internacionales aplican políticas de resolución de conflictos a gran escala sin fijarse en los sistemas y estrategias endógenos de las poblaciones implicadas. En este artículo intentaremos presentar algunos valores, prácticas e instituciones locales que intentan resolver conflictos de todo tipo a pequeña escala en la región de Casamance, donde se vive uno de los conflictos más duraderos del continente africano. Para ello, presentamos los diferentes grupos étnicos que habitan en Casamance y algunas de sus instituciones más características a la hora de mediar entre familias, pueblos o comunidades. Y finalmente invitamos a reflexionar sobre si estas estrategias endógenas podrían ser utilizadas de forma coordinada como contribución al proceso de paz en Casamance.

Analyses of maternal and child mortality rates of five West African countries: Cote d'Ivoire, Guinea, Liberia, Senegal, Sierra Leone

After traveling to a small country in West Africa last summer, I became interested in learning more about the maternal, infant, and child death rates of that particular region of the continent. For the purposes of this paper I limited the number of countries that would be included in this research to five: Cote d'Ivoire, Guinea, Liberia, Senegal, and Sierra Leone. There are three hypotheses that were considered when conducting the research for this paper. The first was that there is no difference in the under five mortality rates for Cote d'Ivoire, Guinea, Liberia, Senegal, and Sierra Leone. The second hypothesis was that there is no difference in the female literacy rates for Cote d'Ivoire, Guinea, Liberia, Senegal, and Sierra Leone. The final hypothesis was that there is no difference in the male literacy rates for Cote d'Ivoire, Guinea, Liberia, Senegal, and Sierra Leone. The data used were collected from publicly available sources that include the CIA World Factbook, the WHO website, the UNICEF website, the Penn World Data table, and the World Bank website. The p-values that were calculated for all three hypotheses were found to be very significant, and all three of the null hypotheses were rejected. ^

Tratamiento con ácido sulfúrico de semillas de la acacia blanca (Robinia pseudo acacia L.) cosechadas en Mendoza

The results obtained in germination test with seeds of "black locust" (Robinia Pseudo Acacia L) previously treated with sulphuric acid concentrated (d. 1.84) are given. Those test were made in order to get a good germination considering the water tight seed coat that those seeds have in a great percentage. The seeds were soaked in the solution for some minutes; the 180 and 210 minutes soaking (90 and 86.5 % respectively) gave the highest percentage and the fasted process of germination, which were higher than those obtained as efective by other researches. The test made would constitute another evidence of the effect of the locality of production upon the degree of water tightness of the Black locust seeds. The author suggests that the previous treatments of the seeds, the rusticity and quick growing of this species and the furrow system of irrigation so common in the zone will enable, perhaps with success the stablishment of woods of this valuable forestal species, by direct seeding.
