We show that these inequalities are tighter than the existing ones for some classes of quantum states.展开更多

METHODS: Convenience sample of 136 women, 64 of whom were wives in polygamous marriages and 72 were wives in monogamous marriages participated in this study. A snowball method of sampling was used, conducted by undergraduate local female students trained to collect data according to culturally competent methods. The following research instruments were deployed: the symptoms checklist-90, the Rosenberg SE, the Life Satisfaction, family function and marital satisfaction. RESULTS: Findings revealed that women in polygamous marriages experienced lower SE, less life satisfaction, less marital satisfaction and more mental health symptomatology than women in monogamous marriages. Many of the mental health symptoms were different; noteworthy were elevated somatization, depression, hostility and psychoticism and their general severity index was higher. Furthermore, "first wife syndrome" was examined in polygamous families, comparing first with second and third wives in polygamous marriages. Findings indicated that first wives reported on more family problems, less SE, more anxiety, moreparanoid ideation, and more psychoticism than second and third wives. CONCLUSION: These results are best understood through consideration of the socio-cultural and economic realities facing these women. Implications for mental health practice, policy and further research are discussed.展开更多

Despite this, there is a widespread contemporary belief that monogamy based on love is the most ethical and natural form of partnering for humans—mononormativism. It has long been accepted that our values influence how we frame and interpret scientific questions. In the article we ask, using the example of mononormativism, how does an individual’s sexual ethics influence how they pursue HIV epidemiology? Using a Social Intuitionalist theoretical framework, we argue that a belief in monogamy-as-normative has contributed to certain researchers dismissing the evidence that the generalized HIV epidemics in parts of Africa are due to higher rates of non-monogamy.展开更多
