Dislocations in basic-nickel decagonal Al–Ni–Co single quasicrystals

We present a study of dislocations in decagonal Al₇₀Ni₂₁Co₉ quasicrystals by means of diffraction contrast analysis as well as convergent-beam electron diffraction in the transmission electron microscope. The nickel-rich Al–Ni–Co quasicrystals show diffraction patterns characteristic of the basic-nickel decagonal phase exhibiting almost no diffuse scattering. We succeeded in growing this phase in the form of large single quasicrystals. The two-beam bright-field images show a homogeneous background and no striation contrast as reported for other Al–Ni–Co decagonal phases. We have, for the first time in a two-dimensional quasicrystal, observed the weak contrast-extinction condition.     

Reversing the Counterfactual Analysis of Causation

The counterfactual analysis of causation has focused on one particular counterfactual conditional, taking as its starting‐point the suggestion that C causes E iff (～C □→ ～E). In this paper, some consequences are explored of reversing this counterfactual, and developing an account starting with the idea that C causes E iff (～E □→ ～C). This suggestion is discussed in relation to the problem of pre‐emption. It is found that the ‘reversed’ counterfactual analysis can handle even the most difficult cases of pre‐emption with only minimal complications. The paper closes with a discussion of the wider philosophical implications of developing a reversed counterfactual analysis, especially concerning the differentiation of causes from causal conditions, causation by absences, and the extent to which causes suffice for their effects.     

ON THE THERAPIST'S YEARNING FOR INTIMACY

From the beginning of clinical psychoanalysis, analysts have been at risk of succumbing to yearnings for intimacy and contact that are stirred up by the heat of the analytic encounter. Recently, as theoretical developments have encouraged us to create moments of meeting (Stern et al. 1998) and have urged us to tolerate the feelings stimulated by enactments, these risks have increased. The author points out that foregoing the realization of this yearning within the analytic relationship and the resultant mourning for the loss of a fantasy or illusion carries a heavy personal price tag for the therapist.     

Using Community Surveys to Inform the Planning and Implementation of Environmental Change Strategies: Participatory Research in 12 Washington Communities

A number of studies have demonstrated the efficacy of environmental change strategies (ECS) in effecting community-level change on attitudes and behaviors related to underage drinking (Treno and Lee in Alcohol Res Health 26:35–40, 2002; Birckmayer et al. in J Drug Educ 34(2):121–153, 2004). Primary data collection to inform the design of these strategies, however, can be resource intensive and exceed the capacity of community stakeholders. This study describes the participatory planning and implementation of community-level surveys in 12 diverse communities in the state of Washington. These surveys were conducted through collaborations among community volunteers and evaluation experts assigned to each community. The surveys were driven by communities’ prevention planning needs and interests; constructed from collections of existing, field-tested items and scales; implemented by community members; analyzed by evaluation staff; and used in the design of ECS by community-level leaders and prevention practitioners. The communities varied in the content of their surveys, in their sampling approaches and in their data collection methods. Although these surveys were not conducted using traditional rigorous population survey methodology, they were done within limited resources, and the participatory nature of these activities strengthened the communities’ commitment to using their results in the planning of their environmental change strategies.     

人类积极发展的资源模型——积极青少年发展研究的一个重要取向和领域

积极青少年发展观(Positive Youth Development Perspective,PYD)自20世纪90年代出现以来迅速推动了发展心理学知识的创新与应用,其中发展资源框架(The Developmental Assets Framework)是研究者进行深入探讨与应用研究的一个重要模型.发展资源是指一系列能够有效促进所有青少年获得健康发展结果的相关经验、关系、技能和价值观,本文在这一概念的基础上介绍了发展资源模型的结构、构建与发展基础以及基于该模型的重要假设及实证研究,并在综述研究的基础上探讨了资源模型的未来研究方向.     

具体情绪对个体建议采纳的影响

通过两个实验探讨了不同评价倾向的情绪对个体建议采纳的影响.实验1采用视频片段诱发被试的恐惧和愤怒情绪,实验2则采用视频片段诱发悲伤和厌恶情绪,根据JAS范式,两个实验均采用硬币估计任务来衡量建议采纳程度.结果 表明:(1)不同情绪对建议采纳程度的影响不同,恐惧情绪状态下被试的建议采纳程度要高于愤怒情绪和中性情绪状态下的...     

违实语义的加工机制

违实句(counterfactuals)是传递与事实相反意义的语句,广泛存在于人们的日常生活中并被用以表达对已知事实的另外假设。研究发现,相对于事实语义,违实语义能够激活双重心理表征/空间(虚拟vs.现实),需消耗更多的认知加工资源。本文分别从句法结构和语境制约两个层面详细探讨了违实语义的加工机制。语境方面,双重语义表征构建与消解的时间进程受到语境相关性的制约,充足的语境信息可以消解事实表征的干扰。句法方面,汉语违实标记的缺失使得汉语母语者更加依赖语境与语用来表达、理解违实义,但尚不明确其在线加工机制与印欧语违实义加工有何异同。后续研究应扩大语言研究范围,关注违实语义加工的个体差异,进一步厘清双重语义表征构建与消解的时间进程及其对语篇加工的影响。     

大学生心理控制源与内疚感和羞耻感对反事实思维的影响

研究以128名大学生为研究对象,采用2 (心理控制源: 外控型、内控型)×2 (自我道德感: 内疚感、羞耻感) 两因素被试间实验设计,考察了外控和内控大学生在内疚感和羞耻感两种不同的自我道德情感下反事实思维内容的差异。结果表明:(1) 心理控制源对大学生反事实思维不同内容的诱发具有重要的影响:外控者更倾向于产生行为和情境导向的反事实思维,而内控者更倾向于产生自我导向的反事实思维。内疚感和羞耻感对大学生反事实思维内容的产生没有直接的影响;(2) 反事实思维内容的产生受到了心理控制源与内疚感和羞耻感两种自我道德情感的交互影响:外控者在羞耻感的启动条件下比在内疚感的启动条件下表现出了更多的行为和情境导向的反事实思维,而内控者在内疚感的启动条件下比在羞耻感的条件下表现出了更多的自我导向的反事实思维。研究结果有助于解释以中西方不同被试而得出的内疚感和羞耻感与反事实思维关系的矛盾结论。     

The reward value of near-miss situations

Svartdal, F. (2011). The reward value of near‐miss situations. Scandinavian Journal of Psychology52, 209–217. What is a “positive” outcome? Clearly, obtaining something attractive is regarded as positive, but so is avoiding something negative. The present paper compared these two types of situations in scenario‐type evaluations. Participants rated positive (P), avoiding negative (AN), and negative (N) outcomes in terms of luck (Experiment 1) and overall positive/negative evaluations (Experiments 2 and 3). The results demonstrated that evaluations of P and AN outcomes were judged as equally positive, but the emotional basis for these evaluations was very different: The feeling of relief was the dominating emotion in AN situations, whereas joy was the dominating emotion in P situations. Overall, these results indicate that avoidance‐induced reward value may be important as a motivating factor in cognition and action.
