班级生态系统对儿童亲社会行为影响的研究述评

依据生态系统观以及班级环境中亲社会行为研究的进展,在班级环境中,与儿童人际互动最密切,对其亲社会行为具有重要影响的两类人群是——同伴和教师。作者把儿童与同伴、儿童与教师之间的互动关系作为班级环境中两个重要生态子系统,依次介绍了班级环境中这两个生态子系统的各成分,以及它们对儿童亲社会行为的影响。文章最后指出,该领域的研究应注重人际间的双向互动、基于观察的互动模式研究、以及重视时间变量对行为过程的影响     

家庭环境类型与青少年亲子冲突解决的关系

以北京829名普通中学生为被试.探讨了家庭环境类型与亲子冲突解决的关系.结果表明: (1)高亲密度、高情感表达、低矛盾性的家庭在亲子冲突解决的关系目标上的得分显著高于其它类型家庭;低亲密度、低表达性、高矛盾性的家庭在权力、公平、自认和自主目标上的得分显著高于其它类型家庭. (2)高亲密度、高表达性、低矛盾性的家庭更多使用积极的冲突解决策略;低亲密度、低表达性、高矛盾性的家庭更多使用消极的冲突解决策略.说明不同家庭环境类型下的青少年亲子冲突解决有不同的特点.     

遗传与环境在食管癌发生发展中的作用

食管癌是我国最常见的恶性肿瘤之一,有明显的地域分布特征,提示环境起着主要作用。但近年来有大量研究表明遗传因素在食管癌的发生中起着不可忽视的作用。食管癌是多种因素作用,多基因参与的疾病,是环境与遗传共同作用的结果。     

Progress in the Molecular-Genetic Study of Intelligence

ABSTRACT— The past decade has seen a major shift in the genetic study of human intelligence; where classic studies aimed to quantify the heritability of intelligence, current studies aim to dissect this heritability into its molecular-genetic components. Five whole-genome linkage scans have been published in the past year, converging on several chromosomal (or genomic) regions important to intelligence. A handful of candidate genes, some of which lie in these genomic regions, have shown significant association to intelligence and the associations have been replicated in independent samples. Finding genes brings us closer to an understanding of the neurophysiological basis of human cognition. Furthermore, when genes are no longer latent factors in our models but can actually be measured, it becomes feasible to identify those environmental factors that interact and correlate with genetic makeup. This will supplant the long nature–nurture debate with actual understanding.     

Quality child care supports the achievement of low-income children: Direct and indirect pathways through caregiving and the home environment

Existing studies of child care have not been able to determine whether higher quality child care protects children from the effects of poverty, whether poverty and lower quality child care operate as dual risk factors, or whether both are true. The objective of the current study was to test two pathways through which child care may serve as a naturally occurring intervention for low-income children: a direct pathway through child care quality to child outcomes, and an indirect pathway through improvements in the home environment. Children were observed in their homes and child care settings at 6, 15, 24, and 36 months. An interaction between family income-to-needs ratio and child care quality predicted School Readiness, Receptive Language, and Expressive Language, as well as improvements in the home environment. Children from low-income families profited from observed learning supports in the form of sensitive care and stimulation of cognitive development, and their parents profited from unobserved informal and formal parent supports. Policy implications are discussed.     

How Do You Say Nature?: Opening the Design Space with a Knowledge Environment

In this paper, we describe a design study on how families in Los Angeles experience nature, with a particular focus on how using alternative formats for research analysis and presentation can enrich a design research inquiry. Conducted in Pasadena, CA as a part of Super Studio, the year-long design research class emphasized knowledge building and sharing through design methods of analysis, exhibition, and concept prototypes. After conducting interviews and engaging participants with probes, the class built the results into an open-ended knowledge environment. The main observation from the exhibition – that Angelenos have a limited vocabulary for describing nature and their interaction with it – helped to define the opportunity for design intervention that created connection points between Angelenos and nature. There are few attempts to describe how probe returns evolve into design concepts. Showcased is a process that depends on the unique affordances of design as the vehicle for discovery and invention.     

Environments That Make Us Smart: Ecological Rationality

ABSTRACT— Traditional views of rationality posit general-purpose decision mechanisms based on logic or optimization. The study of ecological rationality focuses on uncovering the "adaptive toolbox" of domain-specific simple heuristics that real, computationally bounded minds employ, and explaining how these heuristics produce accurate decisions by exploiting the structures of information in the environments in which they are applied. Knowing when and how people use particular heuristics can facilitate the shaping of environments to engender better decisions.     

Modified Dialectical Behavior Therapy and Problem Solving for Obsessive-Compulsive Personality Disorder

The impact of a modified dialectical behavior therapy and problem-solving model is examined on the work environment of a patient with an obsessive-compulsive personality disorder (OCPD). A case study is presented examining the impact this client's OCPD behavior in the work environment and on his subordinates. Discussed are interventions that were useful in treating a motivated patient employing cognitive-behavioral models of treatment for this disorder. The case study focuses on the work setting and the issues tied to the work environment wherein subordinates are required to work under a supervisor with OCPD. Lessons learned, issues and import for further study are offered.
