DECREASING CHILDREN'S RISK TAKING ON THE PLAYGROUND

Playground mishaps are some of the most common sources of injury and are the leading killer of children. The present study used a multiple baseline design across three classrooms (N = 379 children). With minimal teaching and rewards, children decreased and maintained decreased risky playground behaviors on slides. Floor effects on climbers prevented the demonstration of similar effects. The decreases seen in risky slide behavior are discussed within the context of preventive safety training for playground injuries.     

RECONSIDERING RESEARCH ON DIVORCE, FAMILY LIFE CYCLE, AND THE MEANING OF FAMILY

This article analyzes functionalist and normative assumptions about marriage, divorce, family, and gender in developmental models of family life cycle. An interdisciplinary review of the literature in family development, family sociology, and family therapy reveals how a deficit comparison model implicitly informs the discourse in the study of single-parent families, women who are alone, and the adjustment of women and children to divorce. A feminist critique of family life cycle as the prevailing conceptual model in family development and therapy is presented, and postmodern definitions that deconstruct the concept of family are discussed. Future perspectives for research on family life and form are considered in terms of new action theory that considers divorce as a mode of resistance and change for women and families.     

BIOMEDICAL ETHICS: MUSLIM PERSPECTIVES ON GENETIC MODIFICATION

Technology pertaining to genetically modified foods has created an abundance of food and various methods to protect new products and enhance productivity. However, many scientists, economists, and humanitarians have been critical of the application of these discoveries. They are apprehensive about a profit‐driven mentality that, to them, seems to propel the innovators rather than a poverty‐elimination mentality that should be behind such innovations. The objectives should be to afford the most benefit to those in need and to prevent hunger around the world. Another major concern is the safety of genetically modified food. Muslims, as well as those in other religious communities, have been reactive rather than proactive. Muslims must connect scientific knowledge and ethical behavior based on faith. In Islam, there is no divide between the two. God has commanded us to seek knowledge and make discoveries to better our lives and our environment. We are trustees of this world and everything in it. The poor, the sick, and the wayfarers have a right to be fed and cared for. God reminds Muslims continuously that the earth and all the heavens belong to God; therefore, no one should feel hunger, no one should suffer or be prevented from sharing this bounty.     

风险决策中的参照点效应研究

本研究以展望理论和社会决策范式模型为基础,着重探讨三种参照点对个体和群体风险决策产生的影响。３００名被试经实验者设置参照点后分别在个体和群体条件下对不同风险度的博弈方案进行选择。结果表明：（１）个体决策中,损失参照点的被试和无得失经验者比得益者更冒险;（２）得益被试的决策受到社会比较的影响;（３）损失参照点的被试并未对群体决策有更大影响,决定群体决策结果的主要是多数原则。     

风险认知策略的计算机模拟实验

风险认知策略是个体面临风险情景时的风险认知倾向,可以通过个体的行为策略加以判断。本实验采用计算机模拟风险情景,以严格的２×２×３的实验变量设计,研究个体的风险认知策略与风险情景因素的关系。实验结论表明,风险认知策略的调整与风险情景中的实际风险程度（风险概率）、风险信息类型以及对风险情景可控与不可控性的知觉有关。个体的冒险性倾向是相对稳定的心理特征,但风险认知策略的调整不仅与个体的心理特征有关,还与风险情景因素有关。     

工作情景中管理人员的风险认知研究

我国持续进行的经济体制改革,从形式到内容都不可能不对企业有深刻的影响。不管是主动还是被迫的,危机感和竞争意识都在强烈地冲击着人们,对于管理人员尤其如此。因此,作者选择从“风险认知”的角度,探讨处于改革浪潮前列的企业管理人员,在其工作情景下对一些敏感问题的认识。研究发现,不同所有制形式对管理人员的风险认知有一定的影响。“企业效益”仍然是困扰企业管理人员的最大问题。“企业效益”被知觉为最高风险因素。并且,企业经营策略（冒险或保守）与企业效力有很高的相关。     

Advice for Infallibilists: DIVORCE and RETREAT!

This paper comprises a defence of Infallibilism about knowledge. In it, I articulate two arguments in favour of Infallibilism, and for each argument show that Infallibilism about knowledge does not lead to an unpalatable Scepticism if justified belief is neither necessary nor sufficient for knowledge, and if Fallibilism about justified belief is true.     

风险偏好与框架效应对大学生职业决策的影响

在应用Hsee等设计的风险偏好水平问卷对46名大学生进行分组的基础上,通过设计职业决策情境,探究了当代大学生职业决策与其风险偏好、职业方案以及方案的框架性倾向之间的关系。研究结果表明：（1）高风险偏好大学生的职业选择倾向明显高于低风险偏好的大学生,尤其对冒险职业方案的选择中,上述趋势最为明显;（2）框架效应存在于大学生职业决策情境中,他们更倾向于选择采用积极口吻表述的职业方案;（3）大学生对冒险、折中、保守三种方案的职业选择倾向有显著地逐渐增大的趋势。     

银屑病发病的心理社会因素及危险因素间关系的探讨——非条件Logistic回归分析和通径分析

本文对97例寻常型银屑病患者以及71例皮肤科对照组患者进行了成组病例对照性研究。相对危险度分析从36个研究因素中筛选出14项可疑危险因素;非条件Logistic回归分析提示其中8项因素有明显的致病意义;结合专业知识,对这8项危险因素进行通径分析。研究结果表明,银屑病发病是多因素综合作用的结果,心理社会危险因素通过直接或/和间接(联合)作用,影响致病过程。经通径图将各因素的作用大小、作用形式及协同作用关系较直观地描绘出来。     

MAKING BETTER USE OE SCIENTIFIC KNOWLEDGE: Separating Truth from Justice

One major reason that scientific information is not often effectively applied in the formation of social policy is that available methods for coping with the uncertainty in scientific judgments are overlooked. Application of such methods is as necessary as reducing uncertainty through the acquisition of more knowledge for these methods result in the more effective use of knowledge already at hand. Furthermore, failure to cope with uncertainty through explicit, analytical methods results in failure to separate fact (truth) from value (Justice), which in turn results in wasted knowledge and unnecessary dispute. We present four concrete examples of how such circumstances can be avoided.     

REDUCING RISK OF PRESSURE SORES: EFFECTS OF WATCH PROMPTS AND ALARM AVOIDANCE ON WHEELCHAIR PUSH-UPS

People who use wheelchairs are at risk for developing pressure sores. Regular pressure relief, in the form of a wheelchair push-up, is one way to reduce the likelihood of pressure sores. We examined the effects of antecedent (i.e., instructions, audible prompts) and consequent (i.e., alarm avoidance) events on wheelchair push-ups, using a multiple baseline analysis with 2 participants with spina bifida. Results suggest that the combined procedure was more effective than either antecedent or consequent events alone, and there is some evidence suggesting maintenance of effects over time.     

A MEASUREMENT OF THE ADAPTATION OE COLOR VISION TO THE SPECTRAL ENVIRONMENT

Abstract —An exploratory factor analysis of the reflectance spectral distributions of a sample of natural and man-made objects yields a factor pattern remarkably similar to psychophysical color-matching curves. The goodness-of-fit indices from a maximum likelihood confirmatory factor model with fixed factor loadings specified by empirical trichromatic color-matching data indicate that the human visual system performs near to an optimum value for an ideal trichromatic system composed of three linear components. An unconstrained four-factor maximum likelihood model fits significantly better than a three-factor unconstrained model, suggesting that a color metric is better represented in four dimensions than in a three-dimensional space. This fourth factor can be calculated as a nonlinear interaction term between the first three factors: thus, a trichromatic input is sufficient to compute a color space of four dimensions. The visual system may exploit this nonlinear dependency in the spectral environment in order to obtain a four-dimensional color space without the biological cost of a fourth color receptor.
