This paper studies the linkage between international male migration and changes on land inheritance patterns in rural Oaxaca (Mexico). Land inheritance is a long-term exchange between parents and male adult children in Oaxaca: sons are bequeathed with land as long as they provide for their parents (and their wives care for their in-laws) while daughters are excluded from the family patrimony. Drawing on theoretical sample and 37 in depth interviews, this paper argues that intergenerational solidarity based on the parent-son alliance through inheritance is breaking down due to the uncertainty of men´s migration project along with the increase in the fallback position of wives, who may refuse to take care of elderly in-laws. Other alliances emerge instead: parents try to build new alliances with their daughters, bequeathing them agricultural and building plots. However, these new alliances and inheritance shifts are neither a heterogeneous process nor an automatic change and several family and social dimensions must be included to understand the different outcomes.
As the lowest in the caste hierarchy, Dalits in Indian society have historically suffered caste-based social exclusion from economic, civil, cultural, and political rights. Women from this community suffer from not only discrimination based on their gender but also caste identity and consequent economic deprivation. Dalit women constituted about 16.60 percent of India’s female population in 2011. Dalit women’s problems encompass not only gender and economic deprivation but also discrimination associated with religion, caste, and untouchability, which in turn results in the denial of their social, economic, cultural, and political rights. They become vulnerable to sexual violence and exploitation due to their gender and caste. Dalit women also become victims of abhorrent social and religious practices such as devadasi/jogini (temple prostitution), resulting in sexual exploitation in the name of religion. The additional discrimination faced by Dalit women on account of their gender and caste is clearly reflected in the differential achievements in human development indicators for this group. In all the indicators of human development, for example, literacy and longevity, Dalit women score worse than Dalit men and non-Dalit women. Thus, the problems of Dalit women are distinct and unique in many ways, and they suffer from the ‘triple burden’ of gender bias, caste discrimination, and economic deprivation. To gain insights into the economic and social status of Dalit women, our paper will delve more closely into their lives and encapsulate the economic and social situations of Dalit women in India. The analyses of human poverty and caste and gender discrimination are based on official data sets as well as a number of primary studies in the labor market and on reproductive health.
This study examines the role of actual and perceived financial sophistication (i.e., financial literacy and confidence) for individuals' wealth accumulation. Using survey data from the German SAVE initiative, we find strong gender- and education-related differences in the distribution of the two variables and their effects on wealth: As financial literacy rises in formal education, whereas confidence increases in education for men but decreases for women, we observe that women become strongly underconfident with higher education, while men remain overconfident.Regarding wealth accumulation, we show that financial literacy has a positive effect that is stronger for women than for men and that is increasing (decreasing) in education for women (men). Confidence, however, supports only highly-educated men's wealth. When considering different channels for wealth accumulation, we observe that financial literacy is more important for current financial market participation, whereas confidence is more strongly associated with future-oriented financial planning. Overall, we demonstrate that highly-educated men's wealth levels benefit from their overconfidence via all financial decisions considered, but highly-educated women's financial planning suffers from their underconfidence. This may impair their wealth levels in old age.
This paper seeks to analyse the debate on equality between women and men found in the claims against the subjects related to Education for Citizenship. These claims were resolved in the Spanish Supreme Court and High Courts of the Autonomous Communities. In this debate, there is a strong rejection of antidiscrimination law assumptions, namely that the different roles and social roles of women and men have a cultural and social base and it is unnatural, as evidenced by the concept of gender. But many appellants and judgments defend the difference between women and men as if it was informed and legitimated on human nature. Hence gender is considered an ideology, that is, a category of analysis by means of which the reality of true human nature can be concealed or distorted. But these arguments are opposed to recent legal reforms since they are questioning its normative value, by prioritizing certain moral principles against these laws. We are talking about the Organic Law for Effective Equality between Women and Men, the Law on Integrated Protection Measures against Gender Violence and the Law on Education. However their arguments are not fully justified.
The hypothesis that oxidative stress plays a role in the pathogenesis of Alzheimer’s disease (AD) was tested by studying oxidative damage, acitvities of antioxidant enzymes and levels of reactive oxygen species (ROS) in several models. To this end, mouse models transgenic for mutant presenilin (PS1M146L) as well as mutant amyloid precursor protein (APP) and human post mortem brain tissue from sporadic AD patients and age-matched controls were studied. Aging leads to an upregulation of antioxidant enzyme activities of Cu/Zn-superoxide dismutase (Cu/Zn-SOD), glutathione peroxidase (GPx) and glutathione reductase (GR) in brains from C57BL/6J mice. Simultaneously, levels of lipid peroxidation products malondialdehyde MDA and 4-hydroxynonenal HNE were reduced. Additionally, pronounced gender effects were observed, as female mice display better protection against oxidative damage due to higher activity of GPx. Hence, antioxidant enzymes provide an important contribution to the protection against oxidative damage. In PS1M146L transgenic mice oxidative damage was only detectable in 19-22 months old mice, arguing for an additive effect of aging and the PS1 mutation. Both HNE levels in brain tissue as well as mitochondrial and cytosolic levels of ROS in splenic lymphocytes were increased in PS1M146L mice. Antioxidant defences were unaltered. In PDGF-APP and PDGF-APP/PS1 trangenic mice no changes in any of the parameters studied were observed in any age group. In contrast, Thy1-APP transgenic mice display oxidative damage as assessed by increased HNE levels. Reduced activity of Cu/Zn-SOD may explain this observation. Additionally, gender modified this effect, as female APP transgenic mice display higher b-secretase cleavage of APP and simultaneously increased HNE levels and reduced Cu/Zn-SOD activity earlier than male mice, i.e. from an age of 3 months and before the formation of Ab plaques. Reduced Cu/Zn-SOD activity was also found in another APP transgenic mouse model, in APP23 mice. In post mortem brain tissue from sporadic AD patients activities of Cu/Zn-SOD and GPx were however increased, and changes were most pronounced in temporal cortex. Simultaneously, levels of HNE but not MDA were elevated. Additionally, in vitro stimulation of lipid peroxidation led to increased MDA formation in samples from AD patients, indicating that increased activity of Cu/Zn-SOD and GPx are insufficient to protect against oxidative damage. Furthermore, the observed changes were subject to a gender effect, as samples from female AD patients showed increased activities of Cu/Zn-SOD and GPx as well as increased HNE levels, indicating that brain tissue from females is more sensitive towards oxidative damage. Levels of soluble Ab1-40 were positively correlated with with MDA levels and activities of Cu/Zn-SOD and GPx. Additionally, levels of lipid peroxidation products MDA and HNE are gene-dose-dependently modulated by the Apolipoprotein E4 allele, the most important genetic risk factor for AD known so far. While MDA levels were negatively correlated with MMSE scores, a measure for cognitive function, HNE levels were highest in AD patients with moderate cognitive impairment. Hence, increased HNE levels may play an important role in neurodegenerative events at an early disease stage. In summary, oxidative damage, as assessed by increased HNE levels, could be detected in sporadic AD patients and in different transgenic mouse models. The results of this thesis therefore support the further research of pharmacological targets aiming at augmentation of antioxidant defences for therapy or prophylaxis of Alzheimer’s disease.
