AIDS: Globalization and Its Discontents

Abstract. HIV/AIDS has changed from a disease of white gay men in the United States to a pandemic that largely involves women and dependent children in developing countries. Many theologies of disease are necessary to cope with the variety of expressions of this pandemic. Christian theoethical reflection on HIV/AIDS has been largely focused on sexual ethics, with uneven and mainly unhelpful results. Among the ethical issues that shape future useful conversations are globalized economics and resource sharing, the morality and economics of the pharmaceutical industry, and the need for sex education and access to reproductive choice. Considering such issues in international, interreligious, multiscientific contexts is a concrete next step for the religion‐and‐science dialogue. It will put the powerful tools of both fields to the service of the common good.     

易道辩正

易道是易学思想的精髓或内在精神,其最根本的特征是所谓的“一阴一阳之道”。作为易学结构基元的易卦卦象符号,与阴阳观念具有先天性的亲和力,从而使得阴阳观念有了一个可以符号化表征的形式系统。在汉代,阴阳五行与易学成为一个统一的有机整体。两汉的象数理论试图将易道(天道)完全形式化努力的最终结果是“入于礻几祥”,成为一套牵强附会的繁琐哲学。魏晋以后,诸如“时”、“中”一类具有明显的个人独知默会、参悟修证意义的命题,逐渐成为一阴一阳、生生不息的“易道”最为生动的表征。道之真谛,若以易理言之,就是“自强不息”,“与时偕行”。     

伏隔核和中脑腹侧被盖区内食欲素在吗啡奖赏中的作用

实验采用条件性位置偏爱（CPP）模型考察中脑腹侧被盖区（VTA）和伏隔核壳区（NAcSh）内食欲素（orexin）在吗啡奖赏中的作用。Wistar大鼠分为盐水训练组和吗啡训练组。3轮吗啡（或盐水）匹配训练前,双侧VTA或NAcSh内给予OXR1拮抗剂SB334867（VTA: 0, 1, 5μg;NAcSh: 0, 1, 3μg）;或2轮吗啡（或盐水）匹配训练前NAcSh内给予orexin A（0, 2, 4, 6μg）,观察其对吗啡CPP建立的影响。结果表明,VTA内给予SB334867抑制吗啡CPP建立,并存在剂量效应关系;NAcSh内给予SB334867或orexin A均未影响吗啡CPP建立,而orexin A可增加吗啡处理大鼠的运动性。以上结果表明,VTA和NAcSh内的orexin在吗啡奖赏中扮演的角色不同,可能调控成瘾行为的不同成分     

Biopsychology research in China

The early studies on biopsychology in China were classified under the name of physiological psychology and comparative psychology. In 1979 the Division of Physiological Psychology of the Chinese Psychological Society was founded. Fifteen years later, the Brain‐Behavior Research Center was founded at the Institute of Psychology, Chinese Academy of Sciences. The objective of the Center was to establish a multidisciplinary scientific environment for conducting experimental research on the relationship between brain and behaviour as well as the interactions of the mind and body. A wide range of studies in biopsychology has been conducted in China. The most major research areas are: (1) Behavioural and physiological studies of stress: Research work includes the effect of early environment on stressful responses, interactions of behavioural and endocrine responses under stress, effects of emotional stress on immune function, stress and hypertension and the related role of interleukin‐1. (2) Conditioning and immunity: Studies focus on the effects of conditioning in the modulation of bidirectional immune function. Data from different experiments demonstrate that psychological processes are capable of influencing immune function. The neural substrates are also explored. (3) Memory and learning: Studies mostly concentrate on types of memory formation and training stimulus, effect of light exposure and corticosterone on learning and memory, and the role of the hippocampus in learning and memory. (4) Drug addiction: Work mainly focuses on long‐term aspects of addiction, including memory, novelty seeking, motivation‐related models, and the brain mechanisms underlying morphine psychological dependence.     

Career Concerns for People Living With HIV/AIDS

The purpose of this study was to identify the career concerns of people living with HIV/AIDS. The authors used qualitative research methodology to ask participants to discuss the impact their diagnosis has had on their career development concerns and their career goals. Based on participants' interview responses, the authors classified their concerns as relating to career or workplace issues, medical issues, or coping resources. Career counseling implications for each category are discussed.     

Measuring lexical diversity in children who stutter: application of vocd

There is growing but equivocal evidence that the language abilities of young children who stutter (CWS) may be depressed when compared to those of their fluent peers. In particular, the lexical skills of CWS have variously been reported to be weaker or stronger than comparison children in a number of recent studies. One source for such disagreement may be the measures used to compute lexical characteristics of these children’s spoken conversations. In this study, we examined the concurrent validity of two measures of lexical diversity in spontaneous language samples, Type-Token Ratio (TTR) and the newly developed utility vocd (Malvern & Richards, 1997), using a standard test of expressive vocabulary as the comparison measure. Findings indicated that vocd values (“D”) correlated well with standardized measures of expressive vocabulary, while TTR values did not. In addition, both the standardized measure and vocd revealed significantly poorer expressive lexical skills of CWS, whereas TTR analyses did not evidence this difference. Results are discussed in relation to the relative strength of vocd over TTR as a method for describing lexical characteristics of the spontaneous language samples of this population.

Educational objectives: The reader will learn about and be able to (1) identify several common measures of conversational vocabulary and the strengths and weaknesses of each, and (2) compare the performance of the young CWS in this study to their normally fluent peers in terms of vocabulary performance on both formal and conversational measures of vocabulary.     

视知觉无意识对局部形状和颜色特征加工的注意调节

研究了视知觉无意识对局部几何特征加工中的整体优势效应.被试为天津师范大学本科生60名.仪器为pentium III高分辨率计算机,程序用E-prime心理实验软件系统编制而成.被试的任务是判断靶图形中央线条的方向或颜色.用MANOVA分析了启动图形对靶图形局部特征加工的启动效应,发现了视知觉对无意识呈现的图形加工具有形状优势效应,启动图形与靶图形的整体形状相同可以抑制对靶图形局部形状特征的判断.当被试的任务变成判断靶线条的颜色或启动图形的边由连通状态变成不连通时,视知觉无意识对启动图形加工的整体优势效应消失.该结果提示整体优势效应很可能与任务涉及的信息通道密切相关,对局部形状特征的注意很可能涉及对周围整体形状信息加工自动抑制的过程.     

Taking a long look at action and time perception

Everyone has probably experienced chronostasis, an illusion of time that can cause a clock's second hand to appear to stand still during an eye movement. Though the illusion was initially thought to reflect a mechanism for preserving perceptual continuity during eye movements, an alternative hypothesis has been advanced that overestimation of time might be a general effect of any action. Contrary to both of these hypotheses, the experiments reported here suggest that distortions of time perception related to an eye movement are not distinct from temporal distortions for other kinds of responses. Moreover, voluntary action is neither necessary nor sufficient for overestimation effects. These results lead to a new interpretation of chronostasis based on the role of attention and memory in time estimation.     

条件性恐惧记忆消退返回的性别差异

采用预期判断任务考察男女性对已消退的条件性恐惧记忆是否会出现消退返回的现象。结果表明: (1)在对已习得的条件性恐惧记忆消退后4个小时进行测试, 被试整体会出现明显的消退返回现象; (2)对消退返回现象的性别差异进行比较, 女性比男性的消退返回现象更突出, 并且差异显著; (3)与男性相比, 女性对条件性恐惧记忆具有易习得难消退的趋势, 但是性别差异不显著。研究结果验证了消退返回现象存在的普遍性, 并且有着显著的性别差异, 为以后对创伤后应激障碍患者的治疗应考虑性别因素提供了心理学依据。
