巴西医疗保障体系

从巴西医疗保障体系的建立、资金筹集和使用等方面介绍巴西医疗保障体系,重点关注巴西全民统一医疗制度。鉴于巴西与我国在卫生系统绩效和医疗保障制度改革中所面临的相似挑战,试图通过对巴西医疗保障体系比较详细地介绍及与我国进行简单的对比,总结成功经验、吸取教训为我国建立全民覆盖的医疗保障体系提供借鉴和参考。     

The Effects of Images of African American Women in Hip Hop on Early Adolescents’ Attitudes Toward Physical Attractiveness and Interpersonal Relationships

This qualitative study was designed to identify African American early adolescents’ subjective meanings of African American women’s sexuality through an examination of Stephens & Phillips (2003) sexual images—the Diva, Gold Digger, Freak, Dyke, Gangster Bitch, Sister Savior, Earth Mother, and Baby Mama. These eight sexual images both inform and reflect beliefs about African American women’s physical attractiveness. Interpersonal relationship decision making processes also were influenced by these conceptual frameworks of African American women’s sexuality. Findings from this study are important given the tendency of previous researchers to ignore race and intraethnic variations in studies of beliefs about attitudes toward sexuality.     

Anger-congruent behaviour transfers across driving situations

Anger and aggression on the road may sometimes appear unprovoked and unrelated to current driving circumstances. It is unclear whether such anger and aggression arises because of events prior to those circumstances in which anger is experienced and aggression is exhibited. In this study, time pressure and enforced following of a slowly moving vehicle were used to increase drivers' anger in order to assess whether affect and behaviour during a subsequent, non-provocative, drive would change accordingly. Ninety-six drivers drove twice in a simulated urban environment. During the first drive, oncoming traffic and a slowly moving lead vehicle required that half of the drivers travelled far slower than they would choose. During the second drive, drivers again followed slower vehicles and were required to respond to traffic events not encountered in the manipulation drive. Mood (Profile of Mood States) was assessed before and after each drive, and anger evaluations, arousal (heart rate) and behaviour (speed, lane position and collisions) were measured during drives. Anger increased and both mood and driving behaviour deteriorated in drivers exposed to slower lead vehicles, compared with control group drivers. These behavioural differences of speed and lane positioning carried over into the subsequent drive even to driving situations unlike those where provocation had previously occurred. Drivers who had previously been impeded later approached hazards with less caution, and attempted more dangerous overtaking manoeuvres. It is concluded that sometimes dangerous driving may result from anger provoked by circumstances other than those in which the behaviour is exhibited.
