"Managed competition" is Congress' likely response to health-carereform. At the center of managed competition are regional healthinsurance cooperatives or alliances. In some states, these allianceswill face daunting numbers of uninsured and underinsured peopleand a hostile reception from business leaders and state governmentofficials. In other states, alliances may be welcomed as a logicalextension of current efforts to expand access to health care.Uneven support for alliances among the states will affect theimplementation of reform, as is typically the case in federallyorganized programs. However, the visibility, power, and financialresources of alliances will also affect state governments. Henceforth,American federalism may include three centers of power, notjust two, and the impact on state politics could be profound.  相似文献

This study evaluated the impact that Freddie Gray’s death on April, 19, 2015, had on homicides within Baltimore, Prince George’s County, and the rest of Maryland. The numbers of these deaths were compared in the 2 years prior and after his death. The average number of homicide per month in Baltimore and Prince George’s County, but not the rest of Maryland, showed a statistically significant increase in the 2 years after his death, with a sudden spike in homicides in Baltimore immediately following his death. Spatial density (“heat”) maps of homicides showed an increase in clustering of deaths after Freddie Gray’s demise in portions of Baltimore, particularly near his arrest site. Hot spot maps showed a massive expansion of statistically significant clusters of homicides in areas of West and East Baltimore after his death. An emerging hot spot analysis revealed consecutive hot spots in large areas of West Baltimore with new hot spots prominent along the southern edge of this area. A review of the history of Baltimore, as well as discussions with Baltimore homicide detectives, revealed that prior socioeconomic and political trends likely primed Baltimore for the protests and violence that occurred after Freddie Gray’s death. It is probable that a perceived “overcharging” of officers involved in his death by the State’s Attorney resulted in a “pullback” from policing that directly led to increased homicides in Baltimore.  相似文献

Inadequate water, sanitation, and hygiene (WaSH) knowledge and practices affect maternal and newborn morbidity and mortality. This article describes postpartum knowledge, resources, and practices in three rural Ugandan hospitals. A lack of WaSH resources was problematic for both staff and newly-birthed mothers who demonstrated a lack of knowledge about the appropriate use of WaSH resources and the links between WaSH and health protection. These results suggest that in addition to increasing the availability of medical interventions, basic preventative public health practices should be reflected in policy and practice integrated across the spaces inhabited by pregnant women to achieve improved maternal and newborn outcomes.  相似文献

The English cyclist, Beryl Burton, was one of the few women athletes whose performances matched and sometimes surpassed those of men. Despite the potential threat to hegemonic gender relations thus posed, Burton was, with the important exception of a well‐publicised disagreement with her fellow‐cyclist daughter, Denise, an uncontroversial figure and much respected within the male sporting community. While many personal and sporting factors contributed, this was largely the result of her highly public performance of her roles as wife and mother. However, those roles were also skilfully constructed so as to generate the maximum space for her development as an elite athlete. As a woman and as an amateur, she received less media attention than she deserved in her lifetime and, despite being one of the greatest athletes of all time, has received little serious scholarly or wider public attention since her death.  相似文献

Adolescents are exposed to various stressors that may increase the risk for substance use. Due to the detrimental, and potentially long-lasting, effects related to substance use, it is necessary to explore more optimal coping strategies. This study explored the association between substance use and stress among male and female high school students in relation to spirituality as a moderator. To examine these relationships, the study used cross-sectional data collected from 27,874 high school students (Male?=?50.7%, Female?=?49.3%) across 58 high schools in Maryland that included an ethnically diverse sample (49% Caucasian, 30% African American) with an average age of 16 years old. Bivariate results showed differences in substance use, stress, and spirituality between male and female students. Higher rates of substance use were generally found among male students compared to female students; rates tended to be higher among female students for stress and spirituality compared to their male counterparts. Multilevel analyses indicated a positive association between stress and substance use among male and female students after adjusting for demographic and school-level factors. Both male and female students who reported turning to spiritual beliefs when experiencing problems were less likely to use substances. However, the interaction between stress and spirituality was significant for males only. These findings suggest that stress may increase the propensity for substance use and that spirituality might be a viable coping mechanism useful for helping high school students adapt to stressful circumstances and situations.  相似文献

Transgender youth experience negative school environments and may not benefit directly from interventions defined to support Lesbian, Gay and Bisexual (LGB) youth. This study utilized a multi-method approach to consider the issues that transgender students encounter in school environments. Using data from two studies, survey data (total n = 2260, 68 transgender youth) from study 1 and focus groups (n = 35) from study 2, we examine transgender youth’s experience of school harassment, school strategies implemented to reduce harassment, the protective role of supportive school personnel, and individual responses to harassment, including dropping out and changing schools. In both studies, we found that school harassment due to transgender identity was pervasive, and this harassment was negatively associated with feelings of safety. When schools took action to reduce harassment, students reported greater connections to school personnel. Those connections were associated with greater feelings of safety. The indirect effects of school strategies to reduce harassment on feelings of safety through connection to adults were also significant. Focus group data illuminate specific processes schools can engage in to benefit youth, and how the youth experience those interventions.  相似文献
