Essays on intergenerational and regional aspects of water management

This dissertation consists of three essays on different aspects of water management. The first essay focuses on the sustainability of freshwater use by introducing the notion that altruistic parents do bequeath economic assets for their offspring. Constructing a two-period, over-lapping generational model, an optimal ratio of consumption and pollution for old and young generations in each period is determined. Optimal levels of water consumption and pollution change according to different parameters, such as, altruistic degree, natural recharge rate, and population growth. The second essay concerns water sharing between countries in the case of trans-boundary river basins. The paper recognizes that side payments fail to forge water-sharing agreement among the international community and that downstream countries have weak bargaining power. An interconnected game approach is developed by linking the water allocation issue with other non-water issues such as trade or border security problems, creating symmetry between countries in bargaining power. An interconnected game forces two countries to at least partially cooperate under some circumstances. The third essay introduces the concept of virtual water (VW) into a traditional international trade model in order to estimate water savings for a water scarce country. A two country, two products and two factors trade model is developed, which includes not only consumers and producer's surplus, but also environmental externality of water use. The model shows that VW trade saves water and increases global and local welfare. This study should help policy makers to design appropriate subsidy or tax policy to promote water savings especially in water scarce countries.^

Social determinants of fruit and vegetable intake and validation of Pro-Children Eating Habits Questionnaire for 3rd and 5th grade children

BACKGROUND: The Pro Children Eating Habits Questionnaire has been evaluated as a valid and reliable tool in Europe to measure determinants of fruit and vegetable intake for children; however, it has not been validation for United States populations. The purpose of this study was to (1) assess the reliability and discrimination validity of fruit and vegetable correlates for the Pro Children Eating Habits Questionnaire; (2) investigate the predictive validity of determinants of fruit and vegetable consumption for multi-ethnic elementary school children; and, (3) to assess the association of social determinants with fruit and vegetable consumption. METHODS: One hundred and thirty elementary school students from the 3rd and 5th grades completed this cross-sectional study. RESULTS: Fruit and vegetable determinants, had satisfactory internal consistencies. No differences were found between the test and the retest for the individual questions with the exception of the question for mean perceived vegetable intake. The discriminatory validity indicated the questionnaire could show differences across grade and gender levels for barriers of fruit and vegetables but not for other factors. Grade together with gender explained barriers to eating fruit and vegetables. Greater availability of fruit in the home and school was associated with higher frequency of consumption. CONCLUSIONS: The results of this study indicate the Pro-Children Eating Habits Questionnaire may be a reliable and valid tool for assessing fruit and vegetable consumption of children in the United States.

Generational change among women in rural Valencia

The demise of Generalissimo Francisco Franco in 1975 and the subsequent democratization of Spain and its inclusion in the European Community have profoundly altered the patriarchal traditions of Spanish society. This study focused on the changes that women in Moixent, a rural village in Valencia, Spain, have experienced as a result of this liberalization of government policies, modernization, and economic development. ^ The purpose of this research was to illuminate the changing lives of two generations of women and their families in rural Valencia. The qualitative research techniques of participant observation, in-depth interviewing, and narrative analysis were used to present the different frames of reference of the two generations. Young working women in this rural community have come to rely on the help and support of their mothers in their attempts to work outside the home and improve their standard of living. As they enter Spain's modernizing economy their consumption patterns increasingly mimic those promoted by the global media, and especially television. As these young women take jobs outside the home they are having fewer children and dramatically altering the nation's demographic profile. ^ The older generation of women, who lived through decades of deprivation during the Spanish Civil War and Franco's long regime, support their daughters' new independence by assuming the arduous tasks of providing informal day care for their grandchildren and performing a variety of unpaid services for their daughters, including shopping, cooking, and housecleaning. This older generation of grandmothers is assuming a more difficult and demanding workload in what otherwise would be their retirement years. Hence they are the true enablers of their daughters' economic progress and modern patterns of consumption. ^ Other influences from the outside world have altered family farming practices. The participation of women in the harvests has declined, and most harvesting is now done by migrant foreign workers. As young women enter the workforce grandmothers strive to impart traditional values to their grandchildren, in the face of a rapidly changing world. ^

La represión sexual como tema recurrente en la obra de Federico García Lorca

The purpose of this dissertation is to demonstrate that sexual repression is a recurring theme throughout a selection of works by Federico García Lorca. The introductory chapter focuses on the sexual theories of Sigmund Freud and Michel Foucault in setting the foundation for an analysis of sexually frustrated characters. In chapter two, an analysis of Lorca's rural trilogy reveals how marginalized female characters struggle to preserve societal customs that subjugate them to the patriarchal hegemony by limiting their free will and their sexual freedom. The subsequent chapter elaborates on the theme of repression in poems where the oppressed voice expresses and denounces the intolerance and persecution of those who condemn homosexuality through metaphors of darkness, impurity, and barren love. Chapter four analyzes two avant-garde plays where the underlying message is that of a society that hampers the expression of homosexual love by silencing desire and forcing individuals to mask their identities. The conclusion demonstrates once more the effects of society on sexual freedom, as well as explaining that the recurrence of repressed women is not a pretext in portraying the homosexual saga, but a pre-text in presenting them as an equally marginalized group.
