One of the primary objectives of Colombian social health insurance reform was to increase competition among for-profit insurers. Unfortunately, the flat capitated formula creates an opportunity for sickness funds to maximize reimbursement gains by cream skimming--selecting against unhealthy individuals. This paper explores sickness fund selection behavior to evaluate the efficiency losses associated with the introduction of managed competition in Colombia. Data from a 1997 Colombian household survey are analyzed with a bivariate probit model with partial observability using instrumental variables. The model yields some evidence of sickness fund selection based on health status. Public policy options to discourage risk selection by health status are discussed.  相似文献

This paper adds further evidence supporting Jared Diamond’s hypothesis that global technological differences in the pre-modern era were fundamentally due to bio-geographic factors: the time elapsed since the onset of agriculture and husbandry, the size of the population relative to the territories, the shape of continents. An alternative hypothesis, that genetic diversity within populations is the ultimate cause of global inequalities, is also examined. Results show how there is no robust evidence supporting a possible effect of genetic diversity on international differences in population density and technology in the pre-modern era.  相似文献

This article examines the relationships between gender and technology in Spanish feminist praxis online and argues that different perspectives on online feminist community-building offer distinct responses to cyberactivism, which is considered central to sustaining efforts for social change. To ascertain whether Spanish virtual communities and cyberactivism have the potential to address the challenges posed by the relations between gender and technology, we analyse feminist scholar Remedios Zafra's theoretical proposals, and the different ways in which this theory intersects with the cyberactivism put forth by two feminist web portals, Ciudad de Mujeres and Mujeres en Red. We will discuss to what degree particular Spanish feminist theory and practice online adapts to or challenges utopianism regarding the liberating potential of technology. We will also examine how, in the face of critical arguments about such liberatory possibilities, two options present themselves for women's effective use of technology: inhabiting or occupying the web through the construction of feminist communities online.  相似文献

The fight against HIV/AIDS is an example of a global struggle for the promotion of sexual health and the protection of human rights for all, including sexual minorities. It represents a challenge for the understanding of its impact on political, social, and economic processes. My central goal in this piece is twofold. First, I underline the importance of a political and human rights perspective to the analysis of the global response to the pandemic, and I introduce the concept of policy networks for a better understanding of these dynamics. Second, I argue that, in the case of Mexico, the constitution of HIV/AIDS policy networks, which incorporate civil society and state actors, such as sexual minority activists and public officials, and their actions—both domestic and international—have resulted in a more inclusive HIV/AIDS policy-making process. However, serious human rights violations of HIV/AIDS patients and sexual minorities still remain.  相似文献

The objective of the study was to describe and discuss the cases of two women who faced criminal charges, one for attempting to murder her three children and the other for killing her 1-year-old boy. After a forensic psychiatric assessment of their level of criminal responsibility, these patients were considered not guilty by reason of insanity and were committed to forensic mental hospitals. These two patients received a diagnosis of paranoid schizophrenia, according to the DSM-IV-TR criteria. In both cases, psychotic symptoms were present before the manifestation of violent behavior, in the form of persecutory delusions, auditory hallucinations, and pathological impulsivity. The investigation into cases of filicide may contribute powerfully to expand our understanding of motivational factors underlying this phenomenon and enhance the odds for effective prevention.  相似文献

Abstract: Controversy has surrounded the use of antidepressants and suicidal behaviors in youth. This study reviewed the Medical Examiner’s Office records of 253 persons aged 24 years or younger classified as suicides in Miami‐Dade County, Florida, from 1990 to 2007. Information was collected regarding demographic information, suicidal characteristics, psychiatric and psychosocial factors, and toxicology results. Eighty‐five percent of the sample was men, and 53.4% of the subjects were Hispanic. Consistent with previous literature, the existence of antidepressants at autopsy was rare; present in only 6% (n = 15) of the victims. The occurrence of antidepressants was not significantly different between Hispanics (n = 7) and non‐Hispanics (n = 8). The incidence of antidepressants was weakly correlated with a tendency to be men and no history of psychiatric illness. The presence of antidepressants in Hispanic youth suicide victims was similar to non‐Hispanics.  相似文献

Childhood abuse has an important negative influence on long-term executive functioning performance. Although this has been studied in non-offenders (controls), few investigations have examined offender samples. The aims of this study were: to study the influence of childhood abuse history on adulthood executive functioning in offenders, and to examine whether executive performance is affected differentially by different abusive events. It was found that in comparison with controls (n?=?17) and with non-abused offenders (n?=?22), the abused offenders (n?=?18) have poorer performance on psychomotor-cognitive processing speed and cognitive flexibility. In abused offenders, it was also found that physical abuse events primarily and significantly affected adulthood performance in these cognitive abilities. In conclusion, this study helps us to know, preliminarily, the neurocognitive profile of abused offenders and how different abusive events suffered in childhood (e.g. physical and emotional abuse) differentially affect executive functioning of this sample.  相似文献
