Stress and coping among gay men: Age and ethnic differences.

Previous studies suggest that perceived stigmatization of sexual minority status, ethnicity, and age are associated with negative mental health outcomes, and other studies suggest that coping styles may influence these outcomes. However, no studies have examined these relationships among gay men of varying ethnicities and age groups. Three hundred eighty-three Black and White, younger, middle-aged, and older adult gay men completed measures of perceived stigmatization, coping style, and mental health outcomes. Black older adult gay men reported significantly higher levels of perceived ageism than the older White group, significantly higher levels of perceived racism than the younger Black group, significantly higher levels of homonegativity than the younger Black and the White groups, and were more likely to use disengaged coping styles than White gay men. However, Black older adult gay men did not experience significantly higher levels of negative mental health outcomes. Results suggest that further research should examine how older Black gay men, who perceive higher levels of stigma while reporting greater use of less effective coping styles, do not appear to be experiencing more negative mental health outcomes as a result.

2009年北美轮胎生产概况

美国经济2009年1月正处于衰退期,而2010年似乎已进入了扩张期,这意味着经济衰退已经结束。2009年第3季度美国国内生产总值实现了自2008年第1季度以来首次增长。另外,申请失业救济人数和可用房源数量都呈下降趋势,预示着经济复苏的积极向好。美国国家经济研究局称,这也有可能是经济扩张中经济活动的短期逆转。     

IEEE 802.22环境下的认知无线网络功率控制研究

在主用户信干噪比(SINR)门限和认知用户总功率的限制条件下,研究了认知无线网络中的功率控制方法。主用户可容忍的干扰随通信环境的改变而不断变化,所以认知用户需根据主用户的信噪比进行严格的功率控制。仿真结果表明,该功率控制方案能最大化认知用户的传输速率和降低认知用户中断概率,同时主用户的QoS得到有效的保证。
