El índice de la razón entre sexos al nacer las investigaciones sobre la población en el siglo xviii, considerado casi constante durante mucho tiempo, conoce hoy un renovado interés que permite observar indirectamente fenómenos de desciminación muy precoces, según el sexo. A lo largo de las investigaciones realiadas durante los años 30 por el sociólogo Maurice Halbwachs (1877-1945), este artículo pone en evidencia una vaiabilidad ente los sexos al nacer a través de una medición rigurosa. Un examen crítico de sus resultados empíricos permite reevaluar los fenómenos que él mismo quiso delimitar.The sex ratio index at birth studied in population researches from the 17* Century and considered as a constant for a long time, has a renewed interest that makes possible to indirectly observe early phenomena of sex discrimination. Through the Maurice Halbwachs' investigations (1877-1945) during the 1930's, this paper shows the variability between sexes at birth through a rigorous measurement. A critical evalution of his empirical results allows us to re-assess the phenomena he wanted to delimítate.

¿Cuáles son los dilemas éticos que la investigación sobre violencia y memoria le plantea al estudioso del conflicto? ¿Cómo ellos moldean la naturaleza del proyecto antropológico y de las ciencias sociales en general? En el contexto específico de «grupos de apoyo a victimas» en Sur África, uno de los problemas más importantes es la interacción entre «expertos en trauma» y las «victimas.» Este trabajo se concentra en cómo la violencia del silenciamiento, y el contexto histórico que lo produce, se reinscribe a través de la intervención de estos expertos. Este daño es cristalizado en las tensiones que hay ente la voz y el silencio, entre el reconocimiento histórico y la invisibilidad. Uno de los efectos de esta amplificación, que determina los límites y posibilidades de cualquier investigación sobre la memoria colectiva y la violencia, is una reacción en contra de la intervención de expertos en trauma, cuyo trabajo, la producción y diseminación de saberes sobre lo traumático, es percibida por sobrevivientes como otra forma que toma una economía de la sustracción en donde las experiencias violentas y las voces que las tratan de articular son convertidas en mercancías de consumo masivo dentro de nichos concretos como los académicos. En este sentido se podría pensar que el silencio es un artefacto histórico.What are the ethical dilemmas that conducting research on memory in South África poses to the student of conflict and violence? How do they shape the nature of the anthropological endeavor? In the specific context of «victim support groups» in South África, one of the most problematic issues is the one conceming the interactions between «trauma experts» and «victims.» This paper points out that the violence of voicelessness may be re-inscribed through the intervention of these experts. This harm is crystallized in the tensions between voice and silence, and between historical recognition and invisibility. One of the effects of this amplification, which determines the limits and possibilities of any research on memory as it connects to violence, is a widespread reaction against the intervention of these experts, whose work, the production and dissemination of knowledge about trauma, is often perceived by survivors as being part of a broader economy of subtraction where their «experiences» and «voices» have become commodities. In this regard, silence can be viewed as a historical artifact.

Traditionally these pathologies were considered almost exclusive of the industrialized countries, nevertheless the problem this expanding to the countries like Colombia, this perhaps product of the increase in the rate of life and in the acquisition of little healthful styles of life. The objective of this study was to investigate the presence of associated factors of risk with the cardiovascular diseases in a group of students of the medicine program of the Universidad del Magdalena, as part of a work of formative investigation corresponding to the area of Biochemistry. The results were 24% of the investigated subjects display total cholesterol levels and LDL over the safe parameters. The associated factors of risk with these high levels were, the familiar antecedents with a 83% and the overweight with a 50%. This study is constituted in the base for the formulation of a pr oject that it tries to determine the relation between the factors of modifiable and nonmodifiable cardiovascular risk, in the adolescent population of the Santa Marta district.
