CD_4~+ CD_(25)~+调节性T细胞在妊娠与分娩中的作用

近代生殖免疫学研究认为,正常妊娠维持有赖于母胎免疫耐受的形成,耐受一旦失调,就可能妊娠失败,发生如流产,妊娠期高血压疾病,胎膜早破,分娩发动等。近几年来,国内外学者逐渐认识到CD4+CD25+调节性T细胞在妊娠中的重要作用并进行系列研究。本文就目前CD4+CD25+调节性T细胞在妊娠与分娩中的作用作一综述。     

An evaluation of the value of choice-making opportunities in single-operant arrangements: simple fixed- and progressive-ratio schedules

The current study compared the effects of choice and no-choice reinforcement conditions on the task responding of 3 children with autism across 2 single-operant paradigm reinforcer assessments. The first assessment employed simple fixed-ratio (FR) schedules; the second used progressive-ratio (PR) schedules. The latter assessment identified the differential strength of choice-making conditions in promoting task responding relative to no-choice conditions for 2 participants; no differential findings were obtained during the FR assessment.     

任职者任务绩效水平对其工作分析结果的影响

在控制了个体人口统计学变量和排除组织水平变量的影响下,探讨了电厂设计和编辑两个职位任职者的任务绩效水平对于他们Occupational Information Network (以下缩写为O*NET)工作分析问卷评价结果的影响。层次回归结果发现,控制了相关因素后,发电厂设计人员的任务绩效水平能显著影响其对技术性技能的水平评价,编辑的任务绩效水平能显著影响信息处理的重要性评价和水平评价,在一定程度上证实了“工作分析结果差异来源于真实差异”的理论

Sensitivity and bias under conditions of equal and unequal academic task difficulty

We conducted an experimental analysis of children's relative problem-completion rates across two workstations under conditions of equal (Experiment 1) and unequal (Experiment 2) problem difficulty. Results were described using the generalized matching equation and were evaluated for degree of schedule versus stimulus control. Experiment 1 involved a symmetrical choice arrangement in which the children could earn points exchangeable for rewards contingent on correct math problem completion. Points were delivered according to signaled variable-interval schedules at each workstation. For 2 children, relative rates of problem completion appeared to have been controlled by the schedule requirements in effect and matched relative rates of reinforcement, with sensitivity values near 1 and bias values near 0. Experiment 2 involved increasing the difficulty of math problems at one of the workstations. Sensitivity values for all 3 participants were near 1, but a substantial increase in bias toward the easier math problems was observed. This bias was possibly associated with responding at the more difficult workstation coming under stimulus control rather than schedule control.     

In search of a new paradigm for cultural psychology

It is my privilege to be invited to write a response to K.S. Yang's reply to my critique of the methodology he used in his empirical research on individual modernity in Taiwan (Hwang, 2003). Yang's reply consists of three parts: The first part provides a quick overview of the methodology used in his individual traditionality and modernity (T/M) research in Taiwan. The second part presents his reply to my methodological criticisms. The third part is a plea for more and better individual T/M research in Asia. My response consists of three corresponding sections, although I will concentrate on the second part of Yang's text.     

Approaching Terra Incognita with James F. T. Bugental: An Interview and an Overview of Existential-Humanistic Psychotherapy

The purpose of this article is to report on the existential-humanistic approach to psychotherapy advanced by James F. T. Bugental. A brief biography is presented, along with an overview of the method, followed by an interview conducted with Dr. Bugental in November of 2002. Included is a discussion of key concepts such as subjectivity, presence, and the living moment. The major goals of this approach are outlined, along with suggestions and contraindications for use. Directions for future research and consideration are offered.     

阿兰·奈斯论深层生态学

奈斯看来,深层生态学既是一种社会思潮,又是以这种思潮为指导的一场旨在改变现行的人类实践模式的社会运动。作为一种社会思潮,它是一个由一系列基本原理构成的演绎性的逻辑体系。奈斯认为,深层生态学的理论内核是八大原理,而在其背后,还有更为基本的前提与终极规范,即各种生态智慧。而奈斯本人的生态智慧的终极规范是(大)自我实现。     

FUNCTIONAL ANALYSIS AND TREATMENT OF RUMINATION USING FIXED‐TIME DELIVERY OF A FLAVOR SPRAY

A functional analysis suggested that rumination exhibited by an adult with autism was maintained by automatic reinforcement. Next, a preference assessment with three flavor sprays (i.e., flavored sprays used by dieters) showed that apple pie spray was most preferred. Finally, the effects of fixed‐time delivery of the apple pie spray on levels of rumination were evaluated. The spray reduced rumination, and the participant was taught to self‐administer the spray.
