Ethnographic data have frequently been used to examine socialization, but rarely to ground theories of socialization. This paper is an exception. Interest in indigenous representations emerging in situations involving socialization has led to the building of a relational model of socialization, which contrasts with mainstream developmental models of this phenomenon. Socialization is generally defined in terms of cultural learning, the internalization of culture or culture acquisition, that is in terms of the individual's development. The present paper defines it in terms of becoming familiar with a new ‘world’, and a series of changes affecting the structure of the relationship between the human agent and this new world. These structural changes include immersion in a world that is at first strange; subjection to the authority of this world on the basis of acceptance of this authority; and involvement in the world's everyday life structures and activities through doing.  相似文献

The present study investigated pubertal development in girls with maltreatment histories (N = 100), assessed at four time points over 2 years beginning in the spring of their final year of elementary school. This sample is unique, in that participants were subject to an unusual level of environmental risk early in life and resided in foster care at the start of the study. Analyses replicated the previously established association between sexual abuse and earlier onset of maturation and earlier age at menarche. Physical abuse was related to a more rapid tempo of pubertal development across the period assessed. These results strengthen previous investigations of childhood maltreatment and puberty, highlighting the complexity and specificity of early life experiences for later development.  相似文献

In this paper we measure “control” of nodes in a network by solving an associated optimisation problem. We motivate this so-called VL control measure by giving an interpretation in terms of allocating resources optimally to the nodes in order to maximise some search probability. We determine the VL control measure for various classes of networks. Furthermore, we provide two game theoretic interpretations of this measure. First it turns out that the VL control measure is a particular proper Shapley value of the associated cooperative network game. Secondly, we relate the measure to optimal strategies in an associated matrix search game.  相似文献

In social identity analyses of leadership the role of leader group prototypicality (the extent to which the leader is representative of the collective identity) in leadership effectiveness is emphasized. We extend this analysis by identifying role ambiguity as a situational influence that feeds into the desire to reduce uncertainty, as a moderator of the relationship between leader group prototypicality and indicators of leadership effectiveness (perceived effectiveness, job satisfaction and turnover intentions). Role ambiguity is proposed to lead people to turn to their group memberships, making leadership effectiveness more contingent on the extent to which leaders are group prototypical. Results of a survey of n=368 employees of four Italian companies supported this hypothesis. Role ambiguity and leader group prototypicality interacted in predicting perceived effectiveness, job satisfaction and turnover intentions, such that leader group prototypicality was more strongly related to leadership effectiveness for employees experiencing greater role ambiguity.  相似文献

The importance of learning has since long been acknowledged for both business and public sector organizations. However, learning theory and research have tended to neglect the differences between these organizations, and to develop in separate and unrelated directions. To address these developments, this paper purports, first, to develop a theoretical framework that integrates various concepts from the fields of public policy learning and organizational learning, and that is specifically directed at public sector organizations. Second, the paper purports to illustrate the utility of this framework by applying it to policy-making in a Dutch municipality, the Pegasustown prostitution case.  相似文献

This study investigated different types of friendships and the behavioral profiles of different types of friends in relation to individual adjustment. In 102 classes with preadolescents (mean age 11), 737 independent friendship dyads, and in 149 classes with adolescents (mean age 14), 1,102 friendship dyads were identified. At each age group, cluster analyses on the behavioral profiles of the dyads yielded three friendship types, with two types of friends within each friendship type: Socially Withdrawn friendship (Victimized Withdrawn and Prosocial Withdrawn friends), Prosocial friendship (High Prosocial and Less Prosocial friends), and Antisocial friendship (Bullying Antisocial and Antisocial friends). The behavioral profiles of the two friends in Prosocial friendships were marked by similarity and in the other two types by complementarity. Both Victimized Withdrawn and Bullying Antisocial friends were less adjusted than participants without friends while Prosocial friends were more adjusted.  相似文献

Attachment in the Indonesian Caregiving Context   总被引:1,自引:0,他引:1  
The quality of the mother-child attachment relationship, the quality of support mothers provide to their children, and characteristics of the caregiving context were examined in 46 Indonesian mother-child dyads. The distribution of attachment patterns, as assessed with the Strange Situation, showed the proportion of children classified as secure and insecure-disorganized to be comparable to the global distribution as reported in two meta-analyses. An over-representation of resistant children was found within the insecure group, which was comparable to the distribution in Japanese samples. The quality of maternal support, measured in two settings, was highest for secure dyads and lowest for insecure-disorganized dyads. Contextual characteristics were not found to differentiate secure from insecure dyads but were found to discriminate between different types of insecure attachment.  相似文献

Using agency and stewardship theories, this study examines howpublic administrators manage contracting relationships withnonprofit organizations. Interviews were conducted with publicand nonprofit managers involved in social services contractrelationships at the state and county level in New York State.The use of trust, reputation, and monitoring as well as otherfactors influence the manner in which contract relationshipsare managed. The findings suggest that the manner in which nonprofitsare managed evolves over time from a principal-agent to a principal-stewardrelationship but with less variance than the theories wouldsuggest. This results in part from the contextual conditionsthat include the type of service, lack of market competitiveness,and management capacity constraints. The intergovernmental environmentin which social services are implemented and delivered presentscomplex challenges for public managers responsible for managingcontract relationships. The findings from this study documentthose challenges and the corresponding management practicesused with nonprofit contractors.  相似文献

A method is proposed for both estimating and correcting a translational mis-alignment between digital images, taking account of aliasing of high-frequency information. A parametric model is proposed for the power- and cross-spectra of the multivariate stochastic process that is assumed to have generated a continuous-space version of the images. Parameters, including those that specify misalignment, are estimated by numerical maximum likelihood. The effectiveness of the interpolant is confirmed by simulation and illustrated using multi-band Landsat images.  相似文献

The authors propose a goodness-of-fit test for parametric regression models when the response variable is right-censored. Their test compares an estimation of the error distribution based on parametric residuals to another estimation relying on nonparametric residuals. They call on a bootstrap mechanism in order to approximate the critical values of tests based on Kolmogorov-Smirnov and Cramér-von Mises type statistics. They also present the results of Monte Carlo simulations and use data from a study about quasars to illustrate their work.  相似文献
