Applying a self-psychological perspective, this paper explores the effects of cultural racism on a person's sense of self. Racism assaults victims with experiences of being perceived as less-than-human by the social milieu. Such experiences can utterly erode self-esteem and ambition and cause a depression of disenfranchisement whereby one feels abjectly ungrandiose. The paper utilizes a literary example and one from clinical experience to illustrate how chronic experiences of antipathy—derived from cultural racism—can erode a person's sense of self by virtue of the disenfranchisement of grandiosity. 相似文献

The Densest k-Subgraph (DkS) problem asks for a k-vertex subgraph of a given graph with the maximum number of edges. The problem is strongly NP-hard, as a generalization of
the well known Clique problem and we also know that it does not admit a Polynomial Time Approximation Scheme (PTAS). In this paper we focus on
special cases of the problem, with respect to the class of the input graph. Especially, towards the elucidation of the open
questions concerning the complexity of the problem for interval graphs as well as its approximability for chordal graphs,
we consider graphs having special clique graphs. We present a PTAS for stars of cliques and a dynamic programming algorithm
for trees of cliques.

Differences in Delaying Motherhood Across European Countries: Empirical Evidence from the ECHP 总被引:1,自引:0,他引:1
Motherhood postponement and fertility decline have been observed in almost all developed countries. In this article, we aim
to assess some of the potential determinants of first childbirth timing in Europe, in a comparative perspective, using data
from the European Community Household Panel Survey (ECHP). We estimate, separately by country, hazard rates for the timing
at first childbirth conditioning to education and work characteristics. Moreover, in order to explain differences between
European countries, we decompose the differences between rates in the part due to the national population composition by specific
characteristics and the part due to different propensities for women with given characteristics. 相似文献

In this article we discuss some theoretical and methodological perspectives for studying children's neighbourhoods as a social‐pedagogical context. This social‐pedagogical perspective includes a focus in research on a reflective approach based on the acquisition of empirical indicators about the impact of the neighbourhood on children's socialisation. A research outline based on the idea of mapping children's neighbourhoods within their social and historical context is presented as one possible example of such an analysis. 相似文献

Web 2.0, Library 2.0, and the Hyperlinked Library 总被引:3,自引:0,他引:3
Discussions surrounding the concepts of Web 2.0/Library 2.0 are increasing among the library community. This column outlines key principles behind Web 2.0 and provides a brief explanation of social tools, such as blogs, RSS feeds, podcasting, and wikis. The author also provides specific uses and applications of these tools within the library environment to illustrate the Library 2.0 concept. An open framework for library communication or hyperlinked library can result if Library 2.0 philosophies are fully utilized. 相似文献

In the current study, tacts with positive qualifying autoclitics for reading were reinforced in order to determine if this procedure would increase the time spent reading by participants. Participants included 5 children, between 9–10 years old. Participants were individually exposed to 4 free operant sessions during which they were instructed to independently choose play activities. During pre- and post-treatment conditions, no consequences were provided for choosing reading. In addition, 4 treatment sessions were conducted on days separate from the free operant session days, during which the experimenter praised each positive reading-related statement emitted by the participant. Following treatment sessions, 4 out of 5 participants increased the time allocated to reading, suggesting that reading could be increased when praise is delivered contingent upon positive reading-related verbalizations. 相似文献

Given recent changes in the labor force participation and economic standing of women, we ask whether a woman's position in the labor market has become a more important determinant of her position in the marriage market. Unlike much prior research on trends over time in assortative mating, we take an individual‐level approach to the analysis and rely on improved measures of labor market position, such as measuring wives' wages before marriage and considering multiple indicators of husbands' longer term economic standing. Our analysis relies on data from the National Longitudinal Survey of Young Women (N = 759) and the National Longitudinal Survey of Youth (N = 767). Our results are consistent with growth over time in the importance of women's earnings potential in determining their marriage prospects. 相似文献
