An ecological analysis of knowing by wielding.

The ecological approach to perception, as developed by James Gibson, is described and applied to how one knows, by means of the haptic perceptual system, various properties of hand-held objects. Four sets of experiments are reviewed in which subjects reported on the extent, orientation, shape, and fractional components of unseen objects wielded freely. For each task, an invariant specific to the object property in question is identified in the structured arrays of rotational moments and strains produced by the act of wielding. Results are discussed in relation to the concepts of attention and stimulation, as reformulated by the ecological approach, and the general theory of perception as information pickup.     

The urban environment and child pedestrian and bicycle injuries: Interaction of ecological and personality characteristics

It is argued that the study of injuries to child pedestrians and cyclists in urban contexts must involve the study of complex elements interacting within a total environment. This complexity, and the need for further research, is illustrated from a study of 400 child victims in an urban, ecological study, and of 67 individually studied child victims and controls. It is argued that the individual vulnerability of some children puts them at high risk when they live in certain types of urban neighbourhoods.     

Constructing a Tree for Community Leaders: Contexts and Processes in Collaborative Inquiry

This paper presents collaborative research between a university-based team and a grass roots community organization on the south side of Chicago. The purpose of the work is to document the nature of community leadership as expressed by members of the host organization. Using a semistructured interview, 77 community members nominated by the host organization were asked about various aspects of their community work. Qualitative analyses of interview text generated a set of 56 codes concerning different aspects of community leadership as reported by grassroots leaders. These codes were subsequently grouped together into five conceptually linked dimensions of community leadership. A leadership tree that simultaneously analyzes and visually displays each of these five dimensions of community leadership was created. Implications of the methodology used to create the leadership tree are discussed for the salience of qualitative methods in community research.     

Discomfort with space and motion: A possible marker of vestibular dysfunction assessed by the situational characteristics questionnaire

Space and motion discomfort (SMD) refers to the situational specificity of symptoms occurring in some patients with vestibular dysfunction, such as those with balance disorders and some with panic disorder. SMD occurs in situations characterized by inadequate visual or kinesthetic information for normal spatial orientation. We report the results of two studies of the construct validity of the Situational Characteristics Questionnaire (SitQ), which has two subscales, both of which measure SMD: the SMD-I and SMD-II. In Study 1, the SitQ was administered to members of a self-help group for balance disorders, a psychiatric sample consisting of patients with panic disorder, nonpanic anxiety disorders, depression, and a sample of normals. SMD levels were the highest in the self-help balance group, next to the highest in the panic groups, and lowest in the remaining groups. In Study 2, the SitQ was administered to otolaryngological patients with vestibular dysfunction and to patients with hearing loss. SMD levels were higher in the vestibular patients. Data on internal consistency, test-retest reliability, and convergent and discriminant validity are presented. The SitQ, particularly the SMD-II, is recommended for quantifying space and motion discomfort in patients with anxiety and/or balance disorders.Study 1 was funded by MH 40757. Study 2 was funded by a grant from the Upjohn Company and MH 19816.     

团队异质性的平衡性对团队创造力的影响

团队异质性的平衡性是指团队中异质性属性的相对分布情况, 是一个从不平衡到平衡的连续谱概念。作为对团队构成维度的补充, 本研究探究其如何通过团队信息深化施加影响于团队创造力。通过对浙江理工大学451名学生的团队实验研究, 得出结论认为：团队知识异质性的平衡性能够积极影响团队创造力, 且团队信息深化在这一过程中起中介作用, 性别异质性的平衡性与团队创造力之间的关系不显著。这一研究结果将有助于打开团队构成和团队创造力研究的新局面。     

非期望刺激的生态意义信息对无意视盲的影响:情绪效价和精细程度的作用

采用Most(2000)的持续动态的实验范式,以圆圈、抽象面孔和真实面孔为非期望刺激,研究其生态意义信息对无意视盲的影响。研究发现:(1)相对于正性面孔和中性面孔,被试对负性面孔作为非期望刺激时的觉察率更高;而对正性面孔和中性面孔作为非期望刺激时的觉察率无显著性差异;(2)相对于圆圈,抽象面孔和真实面孔作为非期望刺激的觉察率更高,而抽象面孔与真实面孔作为非期望刺激时的觉察率均无显著性差异。结果表明,负性的、精细的非期望刺激的无意视盲率更低,即生态意义信息强的非期望刺激更易捕获注意。     

SARS的流行与可持续发展的生态伦理观

分析生态环境危机对SARS的暴发、流行的影响,认为生态环境危机从根本上说是人类道德的危机.通过对这一突发性的事件的反思,说明保持生态环境的可持续发展的是我们必须树立的生态伦理观.     

试析道教劝善书中的生态伦理思想

道教劝善书作为一种伦理道德教化书 ,其中所述的伦理道德规范不仅用以调节人与人之间、人与社会之间的相互关系 ,而且还进一步推广到调节人与动植物、人与自然的关系 ;它主张自然界生命的平等性 ,倡导“贵生”的生命情怀 ,提出“是道则进 ,非道则退”的生态伦理行为准则 ,从而形成了具有神学特征的以生命为中心的生态伦理观。     

人未到场的生态伦理学研究

在目前的生态伦理学研究中 ,人类中心主义和非人类中心主义围绕着自然物有无道德地位展开了激烈的争论。这种争论的不可调和性以及它们观点的不可公度性 ,表明生态伦理学自身发生了严重的形上学危机。导致这种危机的一个根本原因是 :在没有确立“人是什么”的前提下 ,就展开了人与价值的争论 ,致使生态伦理学研究出现了人的空场。生态伦理的形上学基础 ,不是自然物有无道德地位 ,而是人之为人。人惟有首先成为保护自然环境的人 ,拥有保护自然环境的人性 ,他才能够自觉地保护自然环境。     

Short-Term Repeatability of Stabilometric Assessments

The authors evaluated the short-term (within-day, between-days) repeatability of center of pressure (COP) displacements. COP sway area and speed were obtained in the morning and afternoon of two separate days, both with open (EO) and closed (EC) eyes, in 10 healthy adults. Agreement and variability among conditions were tested by ANOVA and Bland-Altman plots. Mode (EO/EC, area: p = .032; speed: p < .004), and day (day1/day2, area: p = .006; speed: p = .02) showed significant differences. The EC condition and the second test day showed the largest values, with medium-large effect sizes. Time-of-day did not influence COP displacements. Speed had better agreement than area (Bland-Altman plots). COP displacements were well reproducible within-day, but had significant between-days variations. COP assessments should be performed in the same session.
