论中西医结合的过程与层次

中西医结合是一个长期困扰人们的难题。中医理论研究人体外部现象的变化规律,以古代哲学思想为指导,具有整体联系、动态把握的合理内核。而目前现代医学对人体结构和功能的认识,并不能完全揭示生命现象本质,因而也不能完全解释中医现象。这种认识有一个不断发展和深化的过程,自然辩证法观点认为层次越低、结合越紧密。分子导次是具有生物意义的最低层次。人类“基因组”计划的实现可能在一个新的高度阐明人体本质,也使中医现象     

自控摄入小剂量酒精影响熟练驾驶行为的实验研究

一个小样本受试者内设计实验,受试者在实验允许的酒精剂量范围内自由选择摄入量。实验安排饮酒前,酒后３０分钟、１１０分钟和１７０分钟四个测试阶段,分别检验受试者在模拟驾驶和实际驾驶两项任务中的认知行为。酒后３０分钟实际驾驶的技能与其他三个测试期相比存在有意义的差别显著性;模拟测试任务中酒后对红、黄两种信号灯的认知反应时之间呈现显著性差别,酒后１１０分钟对黄色信号灯的反应明显延迟。研究提示：受试对酒精感受性的估计是不可靠的,小剂量酒精也能对驾驶行为构成伤害。     

The role of posttraumatic fear and social support in the relationship between trauma severity and posttraumatic growth among adolescent survivors of the Yaan earthquake

Middle school students in Lushan county (N = 315) were assessed 6 months after the Yaan earthquake using a trauma severity questionnaire, a posttraumatic fear questionnaire, a social support questionnaire and a posttraumatic growth inventory to examine the effects of posttraumatic fear and social support in the relationship between trauma severity and posttraumatic growth (PTG). The results showed that posttraumatic fear mediated the relationship between trauma severity and PTG, and social support moderated the relationship between posttraumatic fear and PTG. These findings suggested that trauma severity could be positively associated with PTG in a direct way or in an indirect way through posttraumatic fear. Moreover, posttraumatic fear had a positive relation to PTG under the condition of high social support level, whereas the relation was non‐significant when the level of social support was low. These results were discussed in terms of their implications for adolescents after trauma.     

The impact of psychological distance on integrative internal dialogs

Negotiators more distanced from the negotiated goal more often exhibit integrative behavior, which maximizes both their individual and joint outcomes. Based on the assumption of an analogy between interpersonal negotiations and internal dialogs simulating social relationships, an experiment was carried out. It aimed to verify if psychological distance (proximal vs. distant perspective on the situation enacted in an internal dialog) affects the processes of integration and confrontation and, consequently, increases the frequency of integrative dialogs. Data from 115 participants (56 women) were analyzed. An increase in psychological distance was found to reduce the intensity of the confrontation process and to cause an increase in the number of integrative internal dialogs.     

Does degree of asymmetry relate to performance? A reply to Boles and Barth

In a recent critique Boles and Barth (2011) argue that their prior study investigating asymmetry/performance relationships (Boles, Barth, & Merrill, 2008) uncovered the “true” association (i.e., negative correlation) between lateralization of visual lexical processes and word recognition performance. They contend that our study reporting positive correlations of lexical asymmetry and reading performance (Chiarello et al., 2009) was flawed and hence inconclusive. In this response we address the two major objections raised by Boles and Barth (2011) regarding our selection of tasks and asymmetry measures. We conclude that the Boles and Barth principle of task purity is not relevant to the stated aims of our investigation, and that our linear regression method of measuring asymmetry is valid given the high level of accuracy for the tasks we reported. Because the aims of each investigation differed, we argue that it is unwise to attempt to fit each study into the framework favored by Boles and Barth (2011).     

The road traveled,the road ahead,or simply on the road? When progress framing affects motivation in goal pursuit

The present research examined the dynamic interplay between the framing of one's progress from an initial state toward an end state (i.e., framed as the distance traveled from the initial state to the current state -‘to-date’ versus framed as the distance left from the current state to the end state -‘to-go’) and construal level in influencing motivation in goal pursuit. In three experiments we found that both state and chronic differences in experienced construal level modulate the impact of progress framing on motivation at a specific stage in goal pursuit, i.e., when consumers are halfway between the initial and end state, but is less consequential at the initial or end stages. This modulation shows that type of framing only affected motivation of people with an abstract, but not a concrete mindset. Under these conditions, progress framed in terms of to-date produced increased motivation compared to a to-go frame. Moreover, perceived goal distance was found to mediate the impact of progress framing on motivation for individuals with an abstract, but not a concrete mindset.     

A Fuzzy Goal Programming Formulation with Multiple Target Levels

The essential activity of a manager is decision making, which is becoming more and more complex, mainly in the multi‐criteria problems. Multi‐choice goal programming (MCGP) is considered as a robust tool in operational research to solve this type of problem. However, in real world problems, determining precise targets for the goals is a difficult task. To deal with such situation, Tabrizi introduced and used in 2012 the concept of membership functions in the MCGP model in order to model the targets fuzziness of each goal. In their model, they considered just only one type of functions (triangular form), which does not reflect adequately the decision maker's preferences that are considered as an essential element for modelling the goal's fuzziness. Their model is called Fuzzy MCGP. In this paper, new ideas are presented to reformulate MCGP model to tackle all types of functions by introducing the (decision maker's) preferences. The concept of indifference thresholds is used in the new formulation for characterizing the imprecision and the preferences associated with all types of the goals. The proposed formulation provides useful insight about the solution of a new class of problems. A numerical example is given to demonstrate the validity and strength of the new formulation.

Relating action to abstract goals increases physical activity reported a week later

ObjectiveThe primary aim of the present study was to investigate whether construing action abstractly versus concretely increases physical activity over a one-week period.Design and methodAn experimental study was conducted in which participants were asked to commit to engaging in physical activity at least four times in the coming week. After making this commitment, participants were assigned randomly to think about the concrete procedures or the abstract purpose of their actions. Additionally, in an attempt to induce differences in level of goal conflict, participants were assigned randomly to receive a reminder of a different or consistent goal. The main outcome variable of interest was the number of minutes spent on physical activity over the following 7-day period.ResultsConsistent with the hypothesis, participants in the abstract condition reported engaging in significantly more minutes of physical activity than did those in the concrete condition. Level of goal conflict did not significantly impact physical activity. The effect of abstract versus concrete thinking on physical activity also was related to the processing of negative affect.ConclusionBy providing evidence that construing action abstractly impacts physical activity, the present investigation makes an important addition to research aiming to identify effective means of increasing physical activity.     

Relationships between perfectionistic strivings,perfectionistic concerns,and competitive sport level

ObjectiveTo determine if the level of competitive sport in which people participate is related to levels of perfectionistic strivings and perfectionistic concerns in sport.DesignA cross-sectional correlational design was employed.MethodA total of 383 (245 female, 138 male) undergraduate students (M age = 20.99 years, SD = 3.40) identified the level of competitive sport in which they were currently involved (i.e., no sport, recreational sport, moderately competitive sport, and highly competitive sport). Participants also completed a domain-specific measure of perfectionism that assessed perfectionistic strivings and perfectionistic concerns in sport.ResultsResults from sequential regression analyses indicated that competitive sport level explained a significant amount of variance in perfectionistic strivings (p < .001) when the overlap between perfectionistic strivings and perfectionistic concerns was controlled. Competitive sport level did not explain a significant amount of variance in perfectionistic concerns when the overlap between perfectionistic strivings and perfectionistic concerns was controlled.ConclusionsFindings indicate that higher (more competitive/serious) levels of competitive sport are associated with higher perfectionistic strivings in sport. Discussion focusses on the potential roles that (a) the competitive sport environment may have upon the development of perfectionistic strivings in sport, and (b) perfectionistic strivings may play in enabling athletes to compete at higher levels of competitive sport.     

亲环境行为影响因素的系统整合模型及启示

近10年来,对亲环境行为前因变量的研究逐渐从行为主体的个体内部因素转向行为相关的社会外部因素。本文对影响亲环境行为的个体、群体以及社会层面的相关变量之间的影响机制进行了系统的梳理,在此基础上提出包含微观(个体内部因素)、中观及宏观(外部情境因素)不同层次的前因变量,并对亲环境意愿与行为加以区分的系统整合模型。根据该模型的理论框架,指出未来对亲环境行为研究的具体方向及对我国环保工作的启示。
