Global Interaction in Classical Mechanics

In this paper, an example is presented for a dynamic system analysable in the framework of the mechanics of rigid bodies. Interest in the model lies in three fundamental features. First, it leads to a paradox in classical mechanics which does not seem to be explainable with the conceptual resources currently available. Second, it is possible to find a solution to it by extending in a natural way the idea of global interaction in the context of what is called interaction by impenetrability. Third, the solution presented throws light on a problem posed and discussed in the recent literature in connection with the mass conservation principle.     

Designing Post-Visit Action Resources for Families Visiting Wildlife Tourism Sites

ABSTRACT

Interpretation at zoos, aquariums, and other wildlife tourism sites is generally designed to raise visitors’ awareness and appreciation of natural resources and alert them to the impact of human activities on wildlife populations. However, there has been little investigation of what prompts visitors to adopt conservation actions, and whether reinforcing on-site messages with post-visit support can assist in this process. The aim of the present research was to firstly, design family learning materials to support and extend the learning that occurs as a result of viewing wildlife; and secondly, to ask families visiting a turtle rookery in Queensland, Australia to use the resources and report on their effectiveness. One hundred Australian families were sampled at the site; 3 months later 45 families returned questionnaires relating to the impact of the support materials on their long-term conservation knowledge, attitudes, and behavior. Components that were rated as particularly effective are presented and the importance of providing post-visit updates that connect visitors directly back to their viewing experience is discussed.     

资源保存理论在组织行为学中的应用：演变与挑战

资源保存理论(conservation of resources theory, COR)是组织行为学研究近30年中被引最高的理论之一。COR的提出源自Hobfoll对临床应激障碍的观察与思考,历经了多次修订后该理论逐步由一个压力–反应模型发展成了一个以个体资源存量及其动态变化解释行为动因的动机理论,形成了一个具有较广泛外延的理论体系。组织行为学是资源保存理论标志性文献的施引文献的核心来源。大量组织行为学研究对COR中的资源损失漩涡、获得螺旋等核心过程进行了实证检验,涉及广泛的研究议题,使COR成为了理解员工心理与行为动因的最具影响力的理论之一。COR在组织行为学中的应用面临一定的挑战,其中有来自认知评价理论、适应理论的观点挑战,也有其作为一个"跨界理论"带来的挑战。组织行为学研究在应用COR时应充分尊重其理论要义,避免削足适履。     

Structural Model of Coping and Emotions Produced by Taking a New Job

The relationship of preventive and combative coping resources to appraisals and emotions produced by taking a new job was investigated at 2 separate times. Participants consisted of 231 graduate students who completed inventories measuring these variables regarding their last employment experience. The results of the structural model suggested that preventive coping resources may affect the appraised desirability of taking a new job as well as Initial emotions related to this event, and that combative coping resources may affect subsequent emotional responses. The implications of these results for timing interventions by employment counselors using stress counseling techniques are discussed.     

Too hot to help! Exploring the impact of ambient temperature on helping

Building on the conservation of resources model, we conducted three studies to explore the link between ambient temperature and individual prosocial behavior. In study 1, analyzing the two‐wave field data from a chain of retail stores in Eastern Europe, we find that, in hot, as opposed to normal temperatures, employees are less likely to act in a prosocial manner. In study 2, we replicate and extend these findings in a randomized controlled experiment by identifying mechanisms underlying the relationship between hot ambient temperature and helping behavior. Specifically, we find that heat increases fatigue that leads to reduction in positive affect and subsequently reduces individual helping. Finally, in study 3, we replicate these findings in a field experiment. Taken together, our study helps to explain how and through what mechanisms ambient temperature influences individual helping. The theoretical and practical implications of our findings are discussed.     

A computational analysis of conservation

An approach to modeling cognitive development with a generative connectionist algorithm is described and illustrated with a new model of conservation acquisition. Among the conservation phenomena captured with this model are acquisition, the problem size effect, the length bias effect, and the screening effect. The simulations suggest novel explanations for sudden jumps in conservation performance (based on new representations of conservation transformations) and for the problem size effect (based on an analog representation of number). The simulations support the correlation-learning explanation of length bias (that length correlates with number during number altering transformations). Some conservation phenomena that so far elude computational modeling attempts are also discussed along with their prospects for capture. Suggestions are made for theorizing about cognitive development as well as about conservation acquisition. A variety of classic puzzles about cognitive development are addressed in the light of this model and similar models of other aspects of cognitive development.     

急性应激对工作记忆的影响受工作记忆负荷调节:来自电生理的证据

急性应激如何影响工作记忆还不清楚。采用电影片断诱发被试的急性应激或中性状态后,让其完成数字N-back任务并同时记录脑电。结果发现,低负荷工作记忆诱发的P3显著大于高负荷工作记忆;在0-back任务中,急性应激组诱发的P3显著大于控制组;而在2-back任务中,这种差异不显著。这些结果表明急性应激对工作记忆的影响受工作记忆负荷调节,支持了双竞争理论模型。     

Resilience in the Context of Chronic Stress and Health in Adults

Over the past several decades, stress research has experienced a broadening of its pathologic focus to encompass the concept of resilience. There is a wealth of research on resilience but no general consensus regarding its conceptualization. Some define resilience as attaining eventual favorable outcomes following exposure to adversity. Others define it as specific relatively short‐term responses characterized by a return to homeostasis after initial disruption due to a stressor, and still others refer to resilience as resources that enable the individual to withstand or recover from major stressors. Many of the existing conceptualizations of resilience are not applicable in the context of chronic stress which is particularly harmful to health. How do adults who experience chronic stress survive, manage, and thrive, and what resources enable them to do so? In this paper, we consider these questions by reviewing traditions of research and definitions of resilience in order to inform an understanding of resilience in general, and for the study of chronic stress in adults. Based on a review of the literature, we developed a taxonomy of resilience resources that can be applied broadly, and guide future research.     

工作压力对建设型和防御型建言的差异影响

以往研究普遍从建言行为的建设性意图特征出发, 探讨其关键前因、产生机制和情境因素, 但却较少关注建言行为的工具性目的。基于资源保存理论, 本研究构建了有调节的中介模型以探讨工作压力影响员工建设型建言和防御型建言的作用机制和边界条件。通过对某建筑企业386名员工进行两阶段调查, 结果表明：工作压力与防御型建言存在正向相关关系, 与建设型建言存在负向相关关系, 自我损耗在其中起中介作用; 另外, 领导开明性正向调节自我损耗和建设型建言的负向相关关系, 并正向调节工作压力通过自我损耗影响建设型建言的间接效应。     

STOIC DISAGREEMENT AND BELIEF RETENTION

Propositions are generally thought to have a truth‐value only relative to some parameter or sequence of parameters. Many apparently straightforward notions, like what it is to disagree or retain a belief, become harder to explain once propositional truth is thus relativized. An account of disagreement within a framework involving such ‘stoic’ propositions is here presented. Some resources developed in that account are then used to respond to the eternalist charge that temporalist propositions can't function as belief contents because they don't allow us to make adequate sense of what belief retention amounts to.     

Not all resources are created equal: COR theory, values, and stress

The common usage of conservation of resources (COR) theory highlights the quantity of resources in explaining stress reactions and responses. To expand the theoretical understanding and explanatory power of COR theory, this study tested the proposition that the perceived importance of an individual's resources is a function of personal values. Using a value framework based on Schwartz (1994), it was expected that values would influence both the appraisal of resource importance and coping behaviors. Results from both student and working samples indicated that while resource importance did not clearly mediate all of the coping outcomes, values did have an influence on the importance an individual assigns to resources. Measurement and theoretical implications related to COR theory are discussed.     

Hermeneutical Injustice and Liberatory Education

Hermeneutical injustice occurs when there is a gap in the interpretive resources available to members of a society due to the marginalization of members of a social group from sense‐making practices. In this paper, I address two questions about hermeneutical injustice that are undertheorized in the recent literature: (1) what do we mean when we say that someone lacks the interpretive resources for making sense of an experience? and (2) how do marginalized individuals develop interpretive resources? In response to (1), I argue that to lack interpretive resources is to lack conceptual skill or know how. In response to (2), I draw on resources from Gilbert Ryle and Andy Clark and provide a model of how marginalized individuals develop new conceptual skills by naming their shared experience and using it as a tool for scaffolding each other's conceptual performance. At the same time, I draw on the work of Gaile Pohlhaus and Kristie Dotson to show how these practices succeed only through the redistribution of epistemic power across differently situated social groups.

基于非逻辑机制的条件推理模式：P—Q映射模型及其实证检验

研究结合数学分析方法,提出了基于非逻辑机制的条件推理模型：P-Q映射模型。并根据这个模型,对人们在不同命题类型奈件下的推理行为进行了预测。预测结果显示,当推理前提为LH和HL型命题时,基于P-Q映射模型的预测结果与基于条件概率模型的预测结果完全一致。但当推理前提为LL和HH型命题时,两种模型给出的预测结果存在差异。实验结果表明,当前提命题为LL和HH型命题时,被试的条件推理行为与P-Q映射模型的预言完全一致。     

Towards a model of stress and human performance

An outline is presented of a model that aims to relate energetical and structural mechanisms of human information processing and to incorporate an interactionally defined stress notion in performance research. The first section summarizes objections to unidimensional notions of arousal and stress. It is concluded that further progress requires the analysis of joint cognitive-energetical processing structures. In the second section two current performance models - in terms of linear stages and resources - are briefly reviewed. Despite a number of problems and objections, it is decided to base the model upon linear stage notions of information processing. This is further elaborated in the third section. In accord with Pribram and McGuinness (1975) three energetical supply systems are proposed which are selectively related to specific cognitive processing mechanisms. Stress is defined as a state of imbalance in the energetical supply which is difficult to restore or to compensate. The final section is devoted to the discussion of some lines of evidence and to suggestions for future research.     

A nine-parameter model for psychological assessment

This paper presents a model for viewing assessment from nine vantage points simultaneously. Each of these dimensions or 'parameters' is divided into sublevels. The power and usefulness of the resultant model stems from the variety of possible unique interactions among these dimensions and their sublevels. The model has the following useful properties: (a) it provides a multidimensional definition of several aspects of psychological assessment, (b) it serves as a checklist and guide for the criticism of existing psychological tests and measures, (c) it has potential heuristic value in the generation of new measures and tests, (d) it is flexible, in that new parameters may be added and sublevels changed to suit specific needs, and (e) it is presented visually as a spatial model, thus allowing the viewer a more 'concrete' appreciation of what are really theoretical interactions.

Designing the human stress ontology: A formal framework to capture and represent knowledge about human stress

A large number of papers have been published on the topic of human stress. There is a need to organise this knowledge under a unifying framework, linking and analysing it in mutual combinations so that new knowledge can emerge. Ontology is an enriched conceptual model for representing domain knowledge. An ontology can be designed to provide a framework for knowledge about human stress. This agreed knowledge model will facilitate knowledge sharing and communications. Additionally, ontologies are machine‐readable and can enable automated programs such as data mining to intelligently access and analyse information. The purpose of this paper is to discuss and explain some of the common stress‐related terms, their definitions, classifications and possible interrelations between them. A top‐layer of the human stress ontology (HSO) model is presented, which will continue to evolve as more research contributions and knowledge become available. It is believed that this framework can be used to build powerful tools to assist researchers and therapists in evaluating stress and facilitating their communication in both research and clinical spaces.     

Disaster Preparedness: Relationships Among Prior Experience,Personal Characteristics,and Distress1

At the peak of a hurricane watch and warning, participants completed a questionnaire asking about their prior experience with a hurricane (property loss and distress), and their degree of preparation, perceived threat, and distress when threatened by Hurricane Emily (Study 1) or Hurricane Fran (Study 2). In Study 1, age, income, internal locus of control, perceived threat, and current distress predicted preparation. Among participants with hurricane experience, age and distress as a result of the hurricane accounted for a significant portion of preparation variance. In Study 2, age, perceived threat, and hurricane experience predicted preparation. The findings support both the conservation of resources stress model (Hobfoll, 1989) and the warning and response model (Lindell & Perry, 1992). Implications of the findings and future research directions are discussed.     

职场排斥对员工家庭的溢出效应：归属需求和工作家庭区隔偏好的作用

以往研究证实了职场排斥会对员工组织内诸多方面产生危害, 然而关于职场排斥向组织外部特别是家庭领域的溢出效应还知之甚少。本研究基于资源保存理论构建了一个有调节的中介效应模型, 探讨职场排斥对员工家庭贬损和家庭满意度的溢出效应和具体机制, 研究结果表明：(1)职场排斥对员工家庭贬损有显著正向作用, 对家庭满意度有显著负向作用; (2)工作压力中介了职场排斥与家庭贬损和家庭满意度的关系; (3)员工归属需求调节了职场排斥对工作压力的影响, 同时调节了工作压力在职场排斥与家庭贬损、家庭满意度之间的中介效应; (4)员工工作家庭区隔偏好调节了工作压力对家庭贬损和家庭满意度的作用, 并且调节了职场排斥通过工作压力对家庭贬损和家庭满意度的中介效应。
