Diagnostico potencial del sector pecuario en Sesquilé

En Colombia el sector pecuario, es uno de los más representativos para el crecimiento y sostenibilidad de la economía del país. El sector aporta el 9% del PIB, sus ventas al exterior representan el 21% del valor de las exportaciones totales y genera el 19% del empleo a nivel nacional y el 66% en las zonas rurales. En el contexto del municipio de Sesquilé, la producción en el sector pecuario ha generado la inconformidad por parte de los habitantes y productores del municipio. Este trabajo de grado se desarrolla bajo la Metodología de Matriz de Marco Lógico, la cual presenta una dinámica de identificación del problema central que afecta al sector pecuario y permite plantear diferentes ejes para encontrar las alternativas más óptimas de mejoramiento al mismo, con el apoyo de la Alcaldía Municipal, los Presidentes de la Juntas de Acción Comunal y los habitantes. Para cumplir con el objetivo de caracterizar el sector pecuario del Municipio de Sesquilé, se tiene en cuenta variables productivas y logísticas, para la identificación de alternativas que permitan la generación de empleo y de ingresos en la población. Se identificaron problemas de carácter social, político, económico, tecnológico y logístico, a los cuales se establecen una serie de recomendaciones con pautas de cómo mejorar y aprovechar las oportunidades potenciales que brinda el sector.

Prevalence, risk factors, and problems associated with dating violence: A literature review

The physical, psychological and sexual violence among the couples of adolescents and young adults that are not married neither cohabiting (well-known generally as “dating violence”), has been object of a vast number of investigations in the last two decades that show a high prevalence inside the adolescent and juvenile population. The objective of this work was to carry out an analysis of the literature in connection with the prevalence, risk factors and difficulties associated with this partner violence type. This analysis allowed to elaborate an outline of the factors that could favor the acts of violence, including the previous experiences of victimization inside and outside the family, the acceptance of the violence toward the couple, and the relationship with pairs that have exercised this form of violence.

Preliminary population study of Methylenetetrahydrofolate Reductase (MTHFR) C677T polymorphism determination in a pilot group of students from the University of Rosario

 Introduction: the 5, 10-methylenetetrahydrofolate reductase (MTHFR) is an essential enzyme in folate metabolism; their polymorphisms have been associated with heart disease risk increase, obstetric problems, neural tube defects in fetuses and cancer susceptibility. This gene has a single nucleotide polymorphism, a C-T change at nucleotide 677, which affects significantly its enzymatic activity. Objective: because of the biological importance of this enzyme and the Colombian population genetic heterogeneity characteristic, a study was performed to determine allele and genotype frequencies of MTHFR C677T polymorphism in healthy individuals, taking into account that in Colombia there are only studies that have involved case-control methodology. Methods: we analyzed this polymorphism trough the amplification of the DNA of a 206 students sample population. Additionally, Colombian overall frequencies were calculated, using data from healthy controls reported in other studies. Results: a Hardy-Weinberg disequilibri m was found in the sample tested. For the Colombian data, we found that the global population was in equilibrium. Conclusion: T allele population frequency seems to be under positive selection pressure, which is reflected in the population allele increase, despite its deleterious effect. A Spanish study reported similar results and identified folic acid supplementation on expectant mothers as a probably cause of this change. 

Advances and limitations in the attention to the problems of housing and urban land in Mexico. An approach from the legal-institutional frame

In this work we analyze the reforms carried out by the Mexican state in the nineties of the 20th century, in the items concerning the policies of housing and urban land, based on an exhaustive review of the main actions, programs and changes in the legal and institutional frame that applies for each of these fields. The nineties represent a "breaking point" in the way the State considers the satisfaction of the right to the housing and attends the offer of urbanized land for a tidy and sustainable urban development. In this period of time, the approach of direct intervention in developing and financing housing and creation of land reserves has changed into another one, ruled by the logic of the market. The balance to the first decade of the 21st century is ambiguous, as neither the housing policy has solved the housing shortage for low-income population, nor the land policy has eliminated the illegal urban growth.
