Marrying Your Mom: Preference Transmission and Women's Labor and Education Choices

This paper argues that the evolution of male preferences contributed to the dramatic increase in the proportion of working and educated women in the population over time. Male preferences evolved because some men experienced a different family model one in which their mother was skilled and/or worked. These men, we hypothesize, were more inclined to marry women who themselves were skilled or worked. Our model endogenizes the evolution of preferences in a dynamic setting and examines how it affected women's education and labor choices. We present empirical evidence based on GSS data that favors our transmission mechanism. We show that men whose mothers were more educated or worked are more likely to marry similar women themselves.

Preference Formation and the Rise of Women's Labor Force Participation: Evidence from WWII

This paper presents intergenerational evidence in favor of the hypothesis that a significant factor explaining the increase in female labor force participation over time was the growing presence of men who grew up with a different family model--one in which their mother worked. We use differences in mobilization rates of men across states during WWII as a source of exogenous variation in female labor supply. We show, in particular, that higher WWII male mobilization rates led to a higher fraction of women working not only for the generation directly affected by the war, but also for the next generation. These women were young enough to profit from the changed composition in the pool of men (i.e., from the fact that WWII created more men with mothers who worked). We also show that states in which the ratio of the average fertility of working relative to non-working women is greatest, have higher female labor supply twenty years later.

Nutritional status and socioeconomic change among Toba and Wichí populations of the Argentinean Chaco

The prevalence of overweight and obesity is growing at an accelerated pace in disadvantaged populations. Indigenous populations all over the world, whose lifestyle is changing rapidly and drastically, seem to be particularly prone to show an increased prevalence of overweight and its co-morbidities among adults. The aim of this study was to evaluate the association between socioeconomic and nutritional statuses in adults of two indigenous populations of the Argentine Gran Chaco: the Toba and Wichí of the province of Formosa. Originally hunter-gatherers, they are now more settled and engage in temporary wage labor and local political positions. A total of 541 adults (>20 years old) participated in the study. Almost 50% of the adult Toba and 34% of the adult Wichí were overweight and 10% of adults in both populations were obese. Socioeconomic status was positively associated with body mass index in both populations. Furthermore, political connectedness with the non-indigenous sector, as in the case of community leaders, was highly correlated with obesity. Differences within and between groups can be explained by biocultural factors that include gender, diet (foraged vs store-bought), lifestyle (sedentary vs more active), and history of political power. Our study highlights the interactions among social, cultural, and political economic variables, such as political hierarchies within the group or degree of social connectedness with community leaders. By making these variables an integral part of our analysis and interpretation, we hope to improve our understanding of the situation of indigenous populations in transition. © 2009 Elsevier B.V.

Transgressions, misdemeanors, and punishment in the legal and social imaginary of ancient greek tragedy

La comedia griega antigua (s. V a.C.) demuestra un particular interés por las acciones delictivas, los delincuentes y toda conducta o apariencia transgresora. En su imaginario inscribe una cartografía propia de la delincuencia que criminaliza a los actores políticos más relevantes de la sociedad de su tiempo, como demagogos y delatores, productos de la democracia más radical. Con ello ejerce una “misión” reparadora, pues la comedia es un género sanador, e imparte su propia justicia -una justicia poética- para alcanzar la concreción de una sociedad utópica ideal.Fil: Fernandez, Claudia Nelida.

Chremylus encounters Blepsidemus: The first quiproquo? (Aristophanes’ Wealth 332–414)

Blepsidemus is associated with the comic figure of the bomolochos, as he serves as a ludicrous counterpoint for Chremylus in his debate with Poverty. But the moment in which Blepsidemus demonstrates all of his potential as a dramatic character occurs during the previous scene to the agon (vv. 332–414), when he takes part in a dialogue with his friend. This was highlighted as the only example of quiproquo (“misunderstanding”) in Aristophanes’ plays. The aim of this paper is to explore the aesthetic efficacy of its composition and its semantic impact on the comedy.Fil: Fernandez, Claudia Nelida.

A formal model for explicit knowledge as awareness of plus awareness that

Since the problem of logical omniscience was identified, several proposals have tried to model the knowledge of ‘real’ agents with limited reasoning abilities. One of the most important proposals, awareness logic, relies on the concept of awareness in order to distinguish what the agent ‘truly’ knows and what she could get out of it. Still, the notion of awareness can be interpreted in different ways: it can be understood as what the agent simply entertains, without having any attitude in favour or against (awareness of), but also as what she has consciously recognised as true (awareness that). A previous proposal introduced a combination of these two possible interpretations at a conceptual level. This presentation proposes a formal framework (a semantic model and a language to describe it) that captures these two interpretations of the notion of awareness, as well as the epistemic notions that arise from their combination, such as implicit knowledge, explicit knowledge or justification. The framework provides tools not only for understanding the notions’ subtle interaction, but also for representing some of the different epistemic actions (deductive inference, changes in awareness, external communication) that affect them.Universidad de Málaga.

Universities, Ignore Silver Students at your Peril

As higher education institutions compete to gain competitive advantage in the areas of student enrolment, engagement, graduate numbers, and programme delivery, are these institutes at risk of missing out on one of the largest growing markets? The cohort of persons aged 65 years and over, is expected to double in size by 2040. But the cohort of those who are currently aged 55+ years is not extensively targeted by higher education institutions globally. Platitudes about ‘mature students’ are often used when discussing this demographic, but educational departments identify any person over 23 years as a ‘mature’ student. Hence, is this term truly targeting the senior population and lifelong learning curiosity? Persons who are 65 years have a lifetime of experience at the time of their retirement, and on average have an additional 20 years in which to share that experience with rates of volunteering highest among the 65 to 74 year old age group [1]. By identifying the barriers of the 50+ year’s cohort to transition to education in different forms and different levels, we can prepare the ground work for easing their inclusion in higher education institutions at, or before retirement
