Scientific progress in the 20th century has shown that the structure of the world is hierarchical. A philosophical analysis of the hierarchy will bear obvious significance for metaphysics and philosophy in general. Jonathan Schaffer’s paper, “Is There a Fundamental Level?”, provides a systematic review of the works in the field, the difficulties for various versions of fundamentalism, and the prospect for the third option, i.e., to treat each level as ontologically equal. The purpose of this paper is to provide an argument for the third option. The author will apply Aristotle’s theory of matter and form to the discussion of the hierarchy and develop a theory of form realism, which will grant every level with “full citizenship in the republic of being.” It constitutes an argument against ontological and epistemological reductionism. A non-reductive theory of causation is also developed against the fundamental theory of causation.  相似文献

在高不确定,高度竞争,高度挑战的任务情景下,领导力在团队中将扮演怎样的角色?变革型领导力与交易型领导力又是如何预测团队任务绩效的?为了回答这些问题,该研究对130名学生被试,31个团队,用ERP沙盘模拟游戏来进行模拟实验。通过高度模拟现实中企业经营的情景,从而提高实验结果的外部效度。实验结果表明,变革型领导力与交易型领导力都能够积极地预测团队任务绩效,消极领导力与任务绩效呈负相关,虽然并没有达到统计学显著水平,但研究结果的方向都支持了实验假设。  相似文献

Category learning can be achieved by identifying common features among category members, distinctive features among non-members, or both. These processes are psychologically and computationally distinct, and may have implications for the acquisition of categories at different hierarchical levels. The present study examines an account of children’s difficulty in acquiring categories at the subordinate level grounded on these distinct comparison processes. Adults and children performed category learning tasks in which they were exposed either to pairs of objects from the same novel category or pairs of objects from different categories. The objects were designed so that for each category learning task, two features determined category membership whereas two other features were task irrelevant. In the learning stage participants compared pairs of objects noted to be either from the same category or from different categories. Object pairs were chosen so that the objective amount of information provided to the participants was identical in the two learning conditions. We found that when presented only with object pairs noted to be from the same category, young children (6 ? YO ? 9.5) learned the novel categories just as well as older children (10 ? YO ? 14) and adults. However, when presented only with object pairs known to be from different categories, unlike older children and adults, young children failed to learn the novel categories. We discuss cognitive and computational factors that may give rise to this comparison bias, as well as its expected outcomes.  相似文献

进谏行为与组织公民行为的关系研究:诺莫网络视角   总被引:1,自引:0,他引:1  
进谏行为和组织公民行为等角色外行为研究近年来备受关注。与组织公民行为相比,进谏行为是一个新的构念。本研究探索了进谏行为的构念内涵,并借鉴诺莫网络思路考察了进谏行为与组织公民行为的关系。问卷研究的结果表明:进谏行为能融入组织公民行为构念,领导公平和情感承诺对两者都具有正面影响,而大五中的宜人性维度对两者的影响表现出差异性;从事角色外行为会导致更高的工作满意感。研究证实了进谏行为与组织公民行为构念内涵的相似性及存在的细微差异。  相似文献

The present research examined the moderating effect of the level of threshold on people's preferences for different leader types in step-level public good dilemmas. It was assumed that the primary focus of people in step-level public good dilemmas is to make sure that the group surpasses the threshold. Consequently, when the level of threshold is difficult to reach people are expected to provide more support for and cooperate with a leader that monitors and controls the contributions made toward the public good. However, if the threshold is easy to surpass people will focus more on whether the obtained public good or bonus will be distributed according to agreements, suggesting that people will provide more support to and cooperate with a leader that monitors and controls the distribution of the bonus. These predictions were confirmed across two experiments using a step-level public good paradigm with a dichotomous (Study 1) and a continuous (Study 2) contribution choice. Moreover, the results also revealed that perceptions of trust accounted, in part, for the effect of level of threshold on people's leadership preferences.  相似文献

Two classes of π are studied whose properties are similar to those of the protoalgebraic deductive systems of Blok and Pigozzi. The first is the class of N-protoalgebraic π-institutions and the second is the wider class of N-prealgebraic π-institutions. Several characterizations are provided. For instance, N-prealgebraic π-institutions are exactly those π-institutions that satisfy monotonicity of the N-Leibniz operator on theory systems and N-protoalgebraic π-institutions those that satisfy monotonicity of the N-Leibniz operator on theory families. Analogs of the correspondence property of Blok and Pigozzi for π-institutions are also introduced and their connections with preand protoalgebraicity are explored. Finally, relations of these two classes with the (, N)-algebraic systems, introduced previously by the author as an analog of the -algebras of Font and Jansana, and with an analog of the Suszko operator of Czelakowski for π-institutions are also investigated.

Community-building initiatives strive to involve residents as the drivers of the change process, involving them in an array of activities including collective action efforts. Recent evaluations of many of these initiatives, however, suggest that developing the levels of resident involvement needed in such efforts is challenging. This study examines the neighborhood conditions that are related to whether and how much residents become involved in individual activism and collective action efforts. A random-digit-dial phone survey of 460 residents in 7 distressed neighborhoods suggested that while demographic variables were relatively unimportant, resident perceptions of neighborhood readiness (i.e., hope for the future and collective efficacy) and capacity for change (i.e., social ties and neighborhood leadership), and the level of neighborhood problems were strongly related to whether and how much residents were involved in individual and collective action efforts. Moreover, different elements of these neighborhood conditions were more or less important depending on the type and level of resident involvement. For example, while perceptions of neighborhood problems was the strongest predictor of whether an individual became involved at all, perceived strength of neighborhood leadership was the strongest predictor of an individual's level of activity. The implications of these findings for practitioners and scientists are discussed.  相似文献

This study investigates associations between depressive problems and classroom social status in a large population cohort of Dutch early adolescents (N = 1046, age 13.52 +/- 0.51, 52.4% girls). Depressive problems were assessed by parent and self-reports and classroom status by peer nominations. We assessed peer status with respect to both achievement-related (being a good learner, being good at sports, being good-looking) and affection-related (being liked, being disliked, being best friend) areas. In boys, depressive problems were most strongly associated with not being good at sports, while in girls the association was strongest for not being liked. The risk of a low status in one area could largely be compensated by a high status in another area.  相似文献

Children's and teachers' perception of social dominance was examined using a behavioral criterion for determining accuracy of verbal judgments. Video records of agonistic interactions were obtained during approximately 60 hours of free-play at two preschool centers. Analyses of social conflict episodes ending in submission revealed linear dominance structures for both groups. Dominance perception was assessed in two ways. Both teachers and children were asked to rank-order a subgroup of children according to dominance. They were also asked to select the more dominant children in a number of predetermined pairs. Results indicated that teachers could accurately judge dyadic dominance relations, and that accuracy among children varied as a function of their status within the group hierarchy. Findings have implications for social dominance assessment methodology, and for the issue of consensual versus ecological validity in developmental studies of social perception.  相似文献
