Differences in Sexual Behaviors and Teen Dating Violence among Black,Hispanic, and White Female Adolescents

We examined differences in sexual behaviors among White, Black, and Hispanic adolescent females exposed to dating or sexual violence (DSV) using the 2009 Youth Risk Behavior Survey. We also examined the interaction effect of exposure to DSV and race or ethnicity on sexual behaviors. Sexual behaviors were significantly associated with both race or ethnicity and DSV; DSV was a stronger predictor of sexual behaviors than race or ethnicity; and the effect of DSV on condom use was more pronounced among Hispanic adolescents, whereas the effect of DSV on birth control use was more pronounced among both Black and Hispanic adolescents. Adolescent health programs should simultaneously address DSV and sexual risk reduction, with particular emphasis on birth control and condom use among ethnic minority populations.     

The speed of visual recognition memory

Two processes are thought to support visual recognition memory (VRM): Familiarity and recollection. The former is generally considered to be faster. However, the relationship between the precise onset of the two processes is unclear. Here, we use a novel paradigm, the SAB (Speed and Accuracy Boosting procedure) that constrains participants to use their fastest strategy and provides a continuous distribution of their reaction times. We show that fast recognition occurs as early as ~370 ms, a limit that appears incompressible whatever types of stimuli were used. In a second experiment, running the SAB in conjunction with a modified version of the remember/know paradigm, we show that responses up to ~420 ms are based solely on familiarity. These time limits of 370 ms and 420 ms provide strong constraints on the neural mechanisms underlying VRM and suggest that the fastest, familiarity-based, responses could rely on the visual ventral stream only.     

Rapid reactions to direct and averted facial expressions of fear and anger

Recent studies have shown that reaction times to expressions of anger with averted gaze and fear with direct gaze appear slower than those to direct anger and averted fear. Such findings have been explained by appealing to the notion of gaze/expression congruence with aversion (avoidance) associated with fear, whereas directness (approach) is associated with anger. The current study examined reactions to briefly presented direct and averted faces displaying expressions of fear and anger. Participants were shown four blocked series of faces; each block contained an equal mix of two facial expressions (neutral plus either fear or anger) presented at one viewpoint (either full face or three quarter leftward facing). Participants were instructed to make rapid responses classifying the expressions as either neutral or expressive. Initial analysis of reaction time distributions showed differences in distribution shape with reactions to averted anger and direct fear showing greater skew than those to direct anger and averted fear. Computational modelling, using a diffusion model of decision making and reaction time, showed a difference in the rate of information accrual with more rapid rates of accrual when viewpoint and expression were congruent. This analysis supports the notion of signal congruence as a mechanism through which gaze and viewpoint affect our responses to facial expressions.     

Employee well-being: A multilevel model linking work and nonwork domains

In this article, we review recent methodological developments that have enabled conceptual advances addressing intraindividual processes leading to psychological well-being. We contend that the introduction of dynamic assessment methodologies for sampling experiences, feelings, and behaviours on and off the job, together with the implementation of multilevel modelling strategies in organizational research on well-being, should lead to the development of richer models of employee well-being (compared to existing theoretical models). Accordingly, we develop a model of employee well-being that considers both personal and situational predictors, and both work and nonwork well-being indicators, as well as the real-time relationships between well-being antecedents and indicators across these two life spheres.     

The time of our lives: Psychological disorders,time perception and the practice of mindfulness

Psychological disorders are associated with a wide variety of distortions of time perception. In this paper, I briefly review what is known about time perception and its disorders and suggest that the practice of mindfulness may be effective by virtue of its effect on our relationship with time.     

Hoody,goody or buddy? How travel mode affects social perceptions in urban neighbourhoods

When travelling through a new environment people can and do make very quick judgements about the local conditions. This paper explores the idea that such judgements are affected by the travel mode they use. We hypothesise that drivers generate a more superficial impression of the things they observe than those who walk because they are exposed to less information. This prediction is based on social psychological research that demonstrates that information that becomes available in “thin slices” affects superficial judgements. A survey study (n = 644) demonstrated that perceptions of a less affluent area are indeed negatively related to more driving and positively related to more walking, but only for those who do not live there. Perceptions of a neighbouring affluent area are positively related to more driving. Two experimental studies (n = 245 and n = 91) demonstrated that explicit (but not implicit) attitudes towards a group of young people in an ambiguous social situation are more negative when they are viewed from the perspective of a car user in particular in relation to a pedestrian perspective. These findings suggest that mode use may affect communities by influencing social judgements.

合理使用抗茵药物的伦理决策

中国是世界上滥用抗菌药物最为严重的国家之一,抗菌药物滥用会导致耐药菌株形成、不良反应发生、加重社会和患者经济负担三个主要问题。人类合理使用抗菌药物成为当今社会关注的热点问题,从临床角度阐述了合理使用抗茵药物中若干医学伦理问题,医疗政策、医院管理对抗菌药物合理使用影响的不可替代性;合理使用抗菌药物是良好医患关系的注释;合理使用抗菌药物是医患关系伦理要求。抗菌药物合理使用要求医生必须要有相应的伦理决策能力;抗菌药物合理使用要求医生要主动参与社会伦理讨论;抗菌药物合理使用是多方面共同努力的结果。     

重组人粒细胞集落刺激因子预防肿瘤化疗后Ⅲ度以上骨髓抑制的疗效分析

探讨重组人粒细胞集落刺激因子(rhG-CSF)对初诊晚期肿瘤患者化疗后骨髓抑制的合理预防用药时机.采用前瞻性随机方法,筛选首次化疗后出现Ⅲ度～Ⅳ度骨髓抑制的肿瘤患者,以化疗前24h内给予rhG-CSF的为预防治疗组;以化疗前未预防性给药为对照组,采用组间对照法,比较两组化疗后骨髓抑制的发生情况.结果发现两组的骨髓抑制发生率,预防组明显低于对照组,且Ⅲ度以上骨髓抑制发生率也明显降低.首次化疗后出现Ⅲ度～Ⅳ度骨髓抑制的肿瘤患者,下次化疗前24h内预防性给予rhG-CSF,能有效控制肿瘤化疗后骨髓抑制的发生,降低感染的风险,值得推广.     

转化医学应用现状及其困境分析

转化医学的理念已经蓬勃发展起来,但对大多数处于临床一线的医生而言,却产生了较多困惑:基础医学与临床医学之间仍相互脱节,许多先进的基础医学研究难以为临床实践所用,基础医学的先进成果向临床的转化难以实现.因此,对于转化医学理念的提出,应有所反思,使转化医学的价值得以充分地发挥.
