A Social Learning Perspective on Childhood Trauma and Same‐Sex Intimate Partner Violence

The family violence and childhood trauma literature has suggested that early adverse experiences create risk factors for intimate partner violence (IPV). Thus, this study used a sample of lesbian, gay, and bisexual (LGB) college students (N = 266) to explore differences among childhood trauma, same‐sex IPV, and IPV acceptance. The authors used survey methodology and multivariate analysis of variance. Results indicated that LGB individuals reporting childhood trauma also reported higher rates of IPV, suggesting implications for research and practice.     

胰岛素研究的新突破

人类与糖尿病抗争的历史最早可上溯到公元前1500年前,但直到20世纪20年代胰岛素才由生理学家Fredrick Banting等发现.自此,挽救了数以百万计的糖尿病患者的生命.随后,人们在研究胰岛素如何调节物质代谢时,意外发现含胰岛素的激化液(Glucose-insulin-potassium,GIK)可改善急性心脏梗死患者的症状.提示,胰岛素还具有其它多方面的生理功能.近期研究证明,胰岛素确有抗心肌坏死与凋亡、进而保护缺血再灌注心肌的作用,这再次引起了人们对胰岛素进行深入研究的兴趣.从胰岛素的发现到对其新的作用机制的认识给我们带来许多有益的启示.

How semantic categorization influences inhibitory processing in middle-childhood: an Event Related Potentials study

Throughout middle-childhood, inhibitory processes, which underlie many higher order cognitive tasks, are developing. Little is known about how inhibitory processes change as a task becomes conceptually more difficult during these important years. In adults, as Go/NoGo tasks become more difficult there is a systematic decrease in the P3NoGo response, indicating the use of effective inhibitory strategies (Maguire et al., 2009). This paper investigates the age at which children employ similar inhibitory strategies by studying behavioral and Event Related Potential (ERP) measures of response inhibition for three Go/NoGo tasks. Seventeen 7-8 year-olds and twenty 10-11-year-olds completed three Go/NoGo tasks that differed in the level of categorization necessary to respond. Both age groups displayed slower reaction times as the tasks became more difficult. Further, both groups displayed the predicted Go vs. NoGo P3 amplitude differences in the two simplest tasks, but no significant P3 differences for the most complex task. The reason for this pattern of responses was different in the different age groups. Similar to adults in previous work, the oldest children showed an attenuation of the P3 NoGo response with task difficulty, and no corresponding changes in the Go amplitude. The younger children displayed the opposite pattern, a significant increase in the Go amplitude with task difficulty, and no changes in the NoGo response. These response patterns indicate that efficient inhibitory strategies are developing throughout middle-childhood.     

糖尿病教育在2型糖尿病防控工作中的重要性

老年糖代谢异常患者血浆NT—proBNP与血管内皮功能早期监测意义

通过检测老年糖代谢异常患者的血浆N末端血清脑钠肽前体（NT—proBNP）水平与肱动脉血管内皮依赖性舒张功能（FMD）,探讨其早期监测意义。共77例观察对象,其中12例血糖正常的健康老人为对照组,65例老年糖代谢异常组患者根据空腹血糖（FBG）和糖耐量2小时（0GTT2h）血糖水平分为空腹血糖受损组（IFG）14例、糖耐量受损组（IGT）23例和2型糖尿病组（DM）28例。各组均检测血浆NT—proBNP水平和无创超声监测FMD。随着血糖代谢异常程度加重,比较正常组,糖代谢异常组的血浆NT—proBNP水平升高（P〈0．01）,FMD调节下降（P〈0．01）;糖代谢异常发展过程中,IFG阶段FMD即出现舒张失调（P〈0．05）;IGT阶段血浆NT-proBNP水平升高有意义并达到无症状心衰诊断标准（P〈0．01）,且FMD出现舒张过度调节,提示收缩和舒张功能双向调节不良。空腹血糖升高增加血管内皮依赖性舒张功能损害,当FBG合并（或）餐后血糖升高,血浆NT—proBNP水平升高可以成为早期预测慢性无症状心功能不全的危险因素。因此,关注老年糖代谢异常早期阶段进程,并联合血浆NT—proBNP水平和血管内皮依赖性舒张功能监测,不仅对靶器官保护具有早期预警意义,而且是临床控制血糖管理的重要而简易的方法之一。     

Form follows function: Learning about function helps children learn about shape

Object functions help young children to organize new artifact categories. However, the scope of their influence is unknown. We explore whether functions highlight property dimensions that are relevant to artifact categories in general. Specifically, using a longitudinal training procedure, we assessed whether experience with functions highlights shape as important for categorization. Seventeen-month-olds were provided experience with novel categories of similarly shaped objects. In Study 1, the function group learned about the objects’ shape-based functions; a control group did not. In Study 2, 17-month-olds were trained on the same categories, but the objects’ shapes and functions were no longer causally related. Only the function group in Study 1 subsequently used shape reliably when categorizing novel objects. These results suggest that function is instrumental in establishing a ‘shape bias’ in early categorization and that it does so via conceptually based processes.
