维生素D3及其受体的临床意义

1,25-(OH)2D3是维生素D在体内发挥生理作用的活性形式.活性维生素D3通过与细胞内特异性维生素D受体结合,除了具有调节钙磷代谢的功能外,还发现其可预防和治疗骨质疏松、心血管疾病、自身免疫性疾病和一些肿瘤等.然而,维生素D缺乏在人群中非常普遍.     

愤恨、惩罚与正义——亚当·斯密惩罚理论的一种解读

愤恨是人性中必不可少的组成部分.在斯密看来,这种通常似乎令人憎恶的激情,其基于合宜性的表达却成为捍卫社会正义与平等的心理机制.作为立即和直接促使人们去惩罚的情感,尽管需要怀疑其合理性,但合宜的愤恨不仅成为社会惩罚的基础,也是正义的保证.它所确立的正义感,肯定惩罚的正当性而确认正义的法则体系,其所衍生的功过赏罚的报偿结构,也将促成人性的完善和社会公正的实现.     

Twelve‐ to 14‐month‐old infants can predict single‐event probability with large set sizes

Previous research has revealed that infants can reason correctly about single‐event probabilities with small but not large set sizes ( Bonatti, 2008 ; Teglas et al., 2007 ). The current study asks whether infants can make predictions regarding single‐event probability with large set sizes using a novel procedure. Infants completed two trials: A preference trial to determine whether they preferred pink or black lollipops and a test trial where infants saw two jars, one containing mostly pink lollipops and another containing mostly black lollipops. The experimenter removed one occluded lollipop from each jar and placed them in two separate opaque cups. Seventy‐eight percent of infants searched in the cup that contained a lollipop from the jar with a higher proportion of their preferred color object, significantly better than chance. Thus infants can reason about single‐event probabilities with large set sizes in a choice paradigm, and contrary to most findings in the infant literature, the prediction task used here appears a more sensitive measure than the standard looking‐time task.     

尊严:自尊、受尊重与尊重

尊严是个体的一种权利。尊严包括自尊、受尊重、尊重三个成分。早在上个世纪初,斯金纳就对尊严与个体的自由、自主,与社会的控制和公正的关系进行过认真的思考。后来的研究发现,尊严也与人们在社会互动中的能力、力量、权势、地位有关联。     

音乐节奏和共餐人数对就餐时间的影响

本实验采用现场实验研究的方法,对不同音乐节奏和共餐人数条件下大学生就餐时间的差异进行了分析。结果表明:(1)总的来说,音乐节奏对就餐时间的主效应是显著的,快节奏音乐下的就餐时间少于慢节奏下的就餐时间;(2)单人组被试就餐时间显著快于多人组被试共餐时间;(3)音乐节奏和共餐人数对就餐时间存在交互作用;(4)在单人就餐时音乐节奏对就餐时间的效应是显著的,而多人共餐则没有这种效应或效应不显著。     

步入涅槃还是走向终结?--对当代医学困境的原点审视和深层反思

当代医学在享受基因时代"圣餐"的同时,也在步入一个危机频发的"问题时代".从原点审视,造成其危机和困境的"本因",是其核心价值系统及其动力体系的根本缺陷所致,其基本的生命观、疾病观陷入到诸多哲学困惑和认识误区,其治疗观的"对抗性思维"更是有违自然伦理的法度,这是当代医学走向更高理论平台的战略切入点.     

沿海某省城市居民主观幸福感纵向研究

本文在沿海某省取样,对该省城市居民主观幸福感进行了历时三年的纵向研究。结果进一步证实中围城市居民主观幸福感量表具有较好的心理测量学特性。对该省城市居民主观幸福感的动态考察表明,SARS对城市居民主观生活质量的负面影响是明显的,SARS过后人们的心理健康体验有升高的趋势,当前客观物质条件仍然对人们的主观生活质量产生突出的影响。     

A test of positive and negative extended intergroup contact in a Chinese minority with perceived group norms and intergroup anxiety as mediators

This article is aimed to examine the effect of Uyghur's (minority group) positive and negative extended contact with Han (majority group) within the background of China. One affective (intergroup anxiety) and two cognitive (perceived in‐group and out‐group norms) variables were tested as potential mediators. A sample of 875 Uyghur minority college students ranging in age from 17 to 25 years completed self‐reported measures of direct contact, positive and negative extended contact, intergroup anxiety, perceptions of in‐group and out‐group norms, out‐group attitudes, and contact intentions. Results revealed that both positive and negative extended contact were associated with out‐group attitudes and contact intentions, over and above the effect of direct contact. The effects of both forms of extended contact were mediated by intergroup anxiety, perceived in‐group, and out‐group norms. Notably, positive extended contact exerted larger effects than negative extended contact. This research highlights the significance of considering both positive and negative extended contact and the potential of extended contact as a means to ameliorate intergroup relations from the perspective of minority groups.     

视觉复杂性和字间距调节汉语发展性阅读障碍儿童的视觉拥挤效应:来自眼动的证据

采用眼动追踪技术,通过笔画数多少构成高低不同的视觉复杂性,操纵文本的字间距,来考察视觉复杂性和字间距对汉语发展性阅读障碍儿童的视觉拥挤效应的影响。结果发现,阅读障碍儿童阅读低视觉复杂性文本时,随着字间距的不断增加,字间距增加到一定程度时（+6 pt）阅读时间最长、总注视次数最多,随后在本实验字间距最大条件下（+12 pt）阅读时间变短、总注视次数变少,正常儿童不存在这种现象。结果表明,文本阅读中,字间距和视觉复杂性对阅读障碍儿童的视觉拥挤效应起到调节作用,低视觉复杂性文本可以降低阅读障碍儿童的视觉拥挤效应,阅读障碍儿童的视觉拥挤效应强度和字间距大小的数量关系呈非线性。
