A propósito de la transversalización de género en un proyecto de desarrollo en la provincia de Santa Elena

El presente trabajo se basa en la experiencia vivida con la población nativa de las comunas Olón, Curía, San José, Las Núñez y La Entrada en la Ruta del Spondylus, al norte de la actual Provincia de Santa Elena, en el proceso de ejecución de proyectos de desarrollo rural y conservación. Se hace referencia a dos casos de proyectos ejecutados con la misma población en diferentes tiempos; en el primer caso se proyectaba la identificación del territorio y la concienciación a la población respecto del cuidado y conservación del bosque y fuentes de agua; y, en el segundo, se proyectaba el manejo integral de la caña guadúa apuntando a mejorar una o varias de las actividades que componen la cadena productiva de este recurso

Figuras de ciudadanía y configuraciones normativas en la escuela secundaria: Estudios de caso en cuatro modelos institucionales en la provincia de Buenos Aires, Argentina

La escuela secundaria es objeto de una profunda preocupación social. La progresiva masificación del nivel, junto con su reciente condición de obligatoriedad e incluso la sanción de diversas normativas reconociendo “derechos” a las y los jóvenes –que van desde derechos sexuales y reproductivos hasta la ley de voto desde los 16 años–, presentan nuevos desafíos no sólo para aquellos en- cargados de diseñar las políticas públicas del sector, sino para los académicos y los distintos actores que cotidianamente transitan por las escuelas secundarias. Este artículo intenta aportar algunas ideas para reflexionar sobre las características que asume la experiencia educativa juvenil en la escuela secundaria actual. En las páginas que siguen buscamos problematizar los significados que adquiere “la ciudadanía” y las relaciones entre los agentes educativos, en particular entre docentes y estudiantes, indagando en sus prácticas cotidianas

The Cosmological Slingshot Scenario: a Stringy Proposal for the Early Time Cosmology

In the Cosmological Slingshot Scenario, our Universe is a D3-brane that extends in the 4d noncompact directions of a warped Calabi-Yau compactification of IIB Supergravity. Early time cosmology corresponds to a period in which the brane moves inside a warped throat where a non-vanishing angular momentum ensures that the trajectory of the brane has a turning point. The corresponding induced metric on the D3-brane experiences a cosmological evolution with a bounce. In this framework, the homogeneity, flatness, and isotropy problems of standard cosmology might be avoided. The power spectrum of primordial perturbations of the brane embedding can be found and it is shown to be in agreement to WMAP data.Comment: Presented at "Ten Years of AdS/CFT: A Workshop Celebrating the Tenth Anniversary of the Maldacena Conjecture", Buenos Aires, Argentina, 19-21 Dec 200

Comment on Ricci Collineations of Static Spherically Symmetric Spacetimes

Esta obra, escrita por Juan Manuel Palacio, propone una mirada renovada sobre el peronismo que incorpora otros matices a la historiografía argentina sobre el periodo y, en este sentido, trabaja sobre algunas construcciones discursivas propias de Perón y otras que han crecido dentro de la disciplina de la historia. El texto es teórica y metodológicamente rico y muy útil a diferentes disciplinas del campo de las ciencias sociales

The Evolution of Consanguineous Marriages in the Archbishopric of Granada, Spain (1900–1979)

In the twentieth century Spain maintained some of the highest rates of consanguineous marriage in Europe. In many regions these rates were still high in the 1950s and 1960s, but then decreased rapidly, and by the 1970s a generalized transformation in mating patterns was underway. In the following decades the marriage of persons closely related by birth became rare. Consanguinity and inbreeding have been much studied in Spain, but almost exclusively in the central and northern regions of the country. This is the first study of a whole large diocese in the southern region of Andalusia. This paper is based on the analysis of 15,440 records of consanguineous unions registered between 1900 and 1979 in the Archbishopric of Granada in Andalusia. In this period, the rate of consanguinity up to second cousins was 5.51%, and the mean coefficient of inbreeding, α, was 2.04 × 10−3. There is a high range of variability within the research area. Thus, the rate of consanguinity was more than three times higher in rural areas (6.74%; α = 2.44 × 10−3) than in the capital city (2.03%; α = 0.93 × 10−3). There was a high frequency of unions between first cousins and first cousins once removed. These amounted to 35.3% and 13% of all consanguineous marriages, respectively, and contributed to 70% of α values. Consanguinity here has been strongly related to local endogamy. Thus 76% of all consanguineous couples were born in the same locality, and 89% resided in the same locality at marriage. By the end of the 1960s premarital migration increased and local endogamy started to decrease. On the other hand, inbreeding is inversely related to spatial endogamy. The more inbred couples such as uncles-nieces (C12) or first cousins (C22) show significantly higher exogamy rates and than second cousins (C33) and third cousins (C44), and higher rates of premarital migration. Neither males nor females in intra-family unions seem to be significantly younger than those in non-consanguineous unions. Considering their temporal evolution, consanguinity rates increased in the first third of the century, reaching a maximum in the late 1920s, when over 7.4% of all marriages were consanguineous (8.3% for the rural areas), and the resulting α value was the highest of the century (α = 2.71 × 10−3 for the whole diocese; α = 3.00 × 10−3 for the rural areas). Rates of inbreeding remained high until the 1950s and decreased thereafter in a period of accelerated emigration to cities, urbanization, industrialization and social modernization. Overall, levels of inbreeding are similar and sometimes larger than those found in dioceses in the Northwest of Spain, although marriages between uncle and niece were less common. Some of the counties in the diocese had very high consanguinity levels, not only the isolated area of La Alpujarra, previously studied, but also other ecological and historical micro-regions (comarcas). These results indicate that the widely accepted North-South divisions of the Iberian Peninsula in terms of consanguinity and inbreeding patterns require considerable re- evaluation
