Group membership is a strong driver of everyday life in humans, influencing similarity judgments, trust choices, and learning processes. However, its ontogenetic development remains to be understood. This study investigated how group membership, age, sex, and identification with a team influenced 39- to 60-month-old children (N = 94) in a series of similarity, trust, and learning tasks. Group membership had the most influence on similarity and trust tasks, strongly biasing choices toward in-groups. In contrast, prior experience and identification with the team were the most important factors in the learning tasks. Finally, overimitation occurred most when the children's team, but not the opposite, displayed meaningless actions. Future work must investigate how these cognitive abilities combine during development to facilitate cultural processes. 相似文献

We have undertaken a critical appraisal of the current English system of law regulating: (1) Provision of services designed to prevent children coming into care of local authorities, which are the authorised agencies for dealing with children who are abused or neglected. (2) Ways of receiving children into care and also ways of terminating care orders. We question whether, and under what circumstances, care orders are really necessary. (3) Periodic reviews of children in care. We are critical of the English system and look to models in the USA as guides towards the possible reform of English law. We take the same perspective when considering termination of parental rights. In our opinion good laws do not of themselves provide the care and love which a child requires, but they make the caring possible by loved and loving adults. We argue that the law must provide the best possible framework to allow adequate caring by members of the non-legal professions, such as social workers and foster parents. At the same time the law must ensure that the rights of parents and children are protected. 相似文献

In an effort to explore the value and feasibility of teaching the principles behind developmentally appropriate practices to parents, 53 families with young children were studied. Parents were randomly assigned to participate or not participate in a three month-long, weekly, parent training program. Following completion of the program members of participating families were less likely to engage in conflict during a puzzle solving task than were members of nonparticipating families. Parents who participated were more likely to take a supportive leadership role and have age-appropriate expectations during a puzzle solving task than were nonparticipating parents. Children in participating families showed better social skills than children in nonparticipating families. Portions of the increase in social skills were related to reductions in family conflict and to the development of a task orientation that was more appropriately focused on process than outcome. Lower family conflict was also related to better gross motor skills in children. 相似文献

Modelling and simulation of switching devices with bond graphs is a subject which has no totally satisfying solutions. In this paper, switching devices are represented by flow or effort sources, with a variable circuit topology at switching time. For the simulation, the usual method uses causality resistors to insure integral causality to energy storage elements. The choice of those resistors is quite arbitrary and can lead to stiff systems. We propose, for linear systems, an approach without such resistors. When components lose the integral causality, the order of the state vector changes, provoking the use of pulse variables. A solution is proposed to compute the amplitude of the pulse and the value of the new variables. 相似文献

In fast-paced and knowledge-intensive environments, licensing partnerships can be powerful levers for market expansion. Research on the management of technology-oriented licenses has nonetheless pointed out the risks of corrosive disputes caused by conflicting interests or misunderstandings among licensing partners. The choice made ex ante on mechanisms for resolving potential disputes is of prime importance in the execution of licensing exchanges. Although the legal literature has widely emphasized the advantages of arbitration towards litigation, public ordering remains the “default” option in managers’ eyes. By adopting a transaction cost economics logic, our study explores the conditions under which licensing partners may prefer arbitration over public ordering during the contractual-design phase. In accordance with our theoretical arguments, findings show that the occurrence of arbitration provisions increases when the coordination orientation adopted by licensing partners is extensive. In situations where both monitoring and coordination orientations are simultaneously extensive, results reveal a greater propensity to prefer arbitration over public ordering. Our research therefore supports the view that corporate decision-makers tend to favor the conciliatory stance and compromising awards typically associated with arbitration, only when exchanges are expected to be highly coordinative. Their preference for arbitration over litigation is magnified when the coordination orientation develops alongside the monitoring orientation. 相似文献

This paper presents some results of a qualitative study carried out in a secondary school in the city of Buenos Aires (Argentina). It examines how two students from poor families responded to, and viewed, aggression by peers at their school. This paper argues that the examination of students’ narratives about aggression (based on classism and sexism) illustrates the analytical usefulness of the moral dimension of social life to unpack crucial aspects of the micro politics of class and gender and processes of identity-making. Following Sayer, this article maps students’ responses to immoral sentiments and misrecognition: the search for respect and respectability, and moral boundary drawing. It demonstrates that these reactions are entangled in students’ class and gender identity-making. It also shows how ‘victims’ are able to regain respect. However, the individualized nature of these processes and the spirals of aggression they instigate demonstrate the fragile and temporary nature of this achievement. 相似文献

ABSTRACTA large diversity of theoretical frameworks exists in the physical education literature. This article focuses on two of those frameworks to examine their compatibility and their complementarity. The classroom ecology paradigm concentrates on the balance between three task systems, two vectors, and programs of actions proposed by the physical education teacher and negotiated by students. The didactique research program studies the teaching and learning processes using the concepts of didactic contract and didactic milieu that focus on how the knowledge content emerges within teacher and students’ joint action. The article underlines the complementarity and the compatibility of the two frameworks when analyzing teaching and learning in physical education. It argues that the gray areas left by the classroom ecology paradigm could be filled with the insights of the didactique research program. A concise example of how the two frameworks have already been utilized is presented. 相似文献

Quality teacher-child interactions are characteristic of effective classrooms resulting in benefits for all children, but may be particularly important for children from low-income families. The purpose of this study was to explore the perception of Illinois Head Start teachers related to how I am Moving, I am Learning (IMIL) could improve the quality of their instruction as measured by the Classroom assessment scoring system (CLASS®), an observation instrument used to assess the quality of teacher-child interactions across three broad domains and their supporting dimensions. While the study found that early childhood professionals perceive IMIL as a meaningful resource, additional research is needed to substantiate the preliminary findings as well as to guide training initiatives that would help Head Start professionals to make the connection between IMIL and the CLASS®. 相似文献
