慢性心力衰竭与恶性肿瘤发病机制的理论比较

阐明慢性心力衰竭的病理生理机制对制定防治策略具有重要的作用.根据"内因"与"外因"的辩证关系,借鉴时肿瘤发病机制的一些认识,从另外一个角度对慢性心力衰竭的发病机制进行细致的剖析,以期为临床防治提供一个全新的方向.     

Human reactions to technological failure: How accidents rooted in technology vs. human error influence judgments of organizational accountability

Two experiments examine how the identification of technology as a causal factor in an organizational accident influences judgments of organizational accountability. In study 1, organizations were found to be held less accountable for their actions when a misfortune was rooted in a computer error than when rooted in human error. The predicted mechanism for this effect, counterfactual thinking, was confirmed. Specifically, technologically induced accidents were found to generate fewer counterfactual thoughts of better possible outcomes than similar accidents resulting from human error. Study 2 replicated the findings of study 1 in a more natural setting and using a less intrusive measure for counterfactual thoughts.     

Sibling relationship quality in early adolescence: child and maternal perceptions and daily interactions

Correspondence between child and maternal perceptions of sibling relationship quality (standards, actual ratings, problems) and children's reports of daily interactions were assessed in 40 early adolescent children (M age=11.5 yrs) and their mothers (n=32). Children completed the Sibling Relationship Questionnaire (Furman & Buhrmester, 1985. Child Development, 56, 448–461) and Daily Checklist ratings of sibling interactions for 14 days. Mothers completed the Parental Expectations and Perceptions of Children's Sibling Relationship Questionnaire (Kramer & Baron, 1995. Family Relations, 44, 95–103). Overall, findings revealed correspondence between child perceptions of sibling warmth and maternal ratings of standards, actual ratings, and problems in sibling warmth but not conflict and rivalry. Maternal and child perceptions of sibling relationship qualities were positively associated with children's reports of ongoing interactions. Finally, regression analyses identified unique maternal and child correlates for both happy and prosocial daily interactions. Findings are discussed in light of recent research and theory on family dynamics. Copyright © 2010 John Wiley & Sons, Ltd.     

Politics perceptions as moderator of the political skill – job performance relationship: A two-study, cross-national, constructive replication

We developed a two-study, cross-national, constructive replication to examine the role of organizational politics perceptions as a contextual moderator of the political skill – job performance relationship. Specifically, we hypothesized that high levels of political skill would demonstrate its strongest positive effects on job performance when politics perceptions were perceived as low. Conversely, we hypothesized that political skill would demonstrate no relationship with job performance under conditions of high politics perceptions. Across studies conducted both in the United States and Greece, the hypothesis received strong support. In settings characterized by lower perceived politics, high levels of political skill predicted significant increases in job performance, whereas these effects were attenuated in environments characterized by high perceived politics. Contributions and implications of this research, strengths and limitations, and directions for future study are discussed.     

Spoon-to-cup fading as treatment for cup drinking in a child with intestinal failure

We treated a child with intestinal failure who consumed solids on a spoon but not liquids from a cup. We used spoon-to-cup fading, which consisted of taping a spoon to a cup and then gradually moving the bowl of the spoon closer to the edge of the cup. Spoon-to-cup fading was effective for increasing consumption of liquids from a cup.     

消费者对犯错品牌评价的时间打折效应及其影响因素

通过研究品牌犯错的时间打折效应,本文试图探讨潜在消费者（未购买者）对犯错品牌评价的心理倾向。实验1研究发现,随着品牌犯错事件时间距离的延伸,消费者对身体性危害-品牌犯错的评价不会改善,即没有出现时间打折效应,而对功能性危害-品牌犯错的评价则逐渐提高,从而表现出时间打折效应。但实验2研究进一步发现,随着品牌犯错事件相关性的增强,功能性危害-品牌犯错的时间打折效应也消失。结论：潜在消费者对犯错品牌评价的心理倾向表现为“消费者防御”,并且身体性危害-品牌犯错启动的消费者防御要强于功能性危害。     

成败反馈对大学生核心自我评价的影响：任务重要性、外向性的调节作用

该研究以247名大学生为被试,采用2（反馈类型：成功、失败）×2（任务重要性：重要任务、不重要任务）×2（外向性：内向、外向）组间设计探讨成败反馈对大学生核心自我评价的影响,以及任务重要性和外向性在其中的调节作用。结果表明：（1）反馈类型、任务重要性和外向性对核心自我评价变化的主效应及三者的交互作用效应均显著。（2）成败反馈与任务重要性对核心自我评价变化存在显著的交互作用;简单效应分析表明,在失败反馈条件下,执行重要任务被试核心自我评价的下降幅度显著大于执行不重要任务被试核心自我评价的下降幅度。（3）成败反馈与外向性对核心自我评价变化存在显著的交互作用;简单效应分析显示,在失败反馈条件下,外向被试核心自我评价的下降幅度显著小于内向被试。（4）在失败反馈条件下,任务重要性和外向性对核心自我评价的变化存在交互作用。     

组织政治知觉对乡村教师离职意向的影响:组织公平和组织认同的中介作用

以353名乡村中小学教师为样本,采用结构方程模型等统计方法,分析了组织政治知觉对乡村教师离职意向的影响,以及组织公平和组织认同的中介作用。结果表明：（1）组织政治知觉与乡村教师离职意向之间存在显著正相关,组织政治知觉与组织公平之间存在显著负相关;组织公平与组织认同之间存在显著正相关;组织认同与乡村教师离职意向之间存在显著负相关。（2）组织公平和组织认同在组织政治知觉对乡村教师离职意向的影响中起双重中介作用。     

Trying and the Arguments from Total Failure

New Volitionalism is a name for certain widespread conception of the nature of intentional action. Some of the standard arguments for New Volitionalism, the so-called arguments from total failure, have even acquired the status of basic assumptions for many other kinds of philosophers. It is therefore of singular interest to investigate some of the most important arguments from total failure. This is what I propose to do in this paper. My aim is not be to demonstrate that these arguments are inconsistent or that total failure and naked tryings are metaphysically impossible. Rather, my aim is be to build a case against the possibility of naked, independently existing tryings, by questioning how well we understand the scenarios invoked in their favour. Thus, rather than attempting to present a definitive metaphysical refutation of New Volitionalism, I attempt to diminish or demolish its underlying motivation.

Peer Perceptions and Liking of Children with Anxiety Disorders

Examined three aspects of childhood anxiety and peer liking: (1) whether or not children can detect anxiety in age-mates, (2) the degree to which peer-reported anxiety, self-reported anxiety, and presence of anxiety disorders are associated with peer liking, and (3) whether or not self-reported anxiety and presence of anxiety disorders are associated with peer liking after controlling for peer-reported anxiety. Peer raters (9.5–12.5 years) rated videotaped speech samples of target children with anxiety disorders (AD; 9.5–13 years) and target children without anxiety disorders (NAD; 9.5–13 years). Peer-rated anxiety was positively correlated with target children’s self-reported anxiety and was higher among children with AD and children with social phobia (SP). Peer liking was inversely related to peer-reported anxiety and was lower for target children with SP. Target children with SP were liked less regardless of how anxious peers perceived them to be. Peer rater and target child demographics did not moderate the relationship between peer-rated anxiety and peer liking.
