We examined several models representing the relations among parenting practices, family structure, peer pressure, and drug use in a sample of 443 seventh graders. The setting was an urban school system serving a high percentage of African American students from low-income families. Analyses using structural equation modeling supported a mediation model in which both peer pressure and parenting practices had direct effects on drug use, with peer pressure mediating the influence of parenting. Within this model, family structure had a significant direct effect on parenting, however, contrary to hypotheses, children from two-parent families were more likely to report that they received adequate parenting than were children from single-parent extended families. Several gender differences were also found. Peer pressure was more highly related to drug use for girls than for boys, and the relation between parenting and peer pressure was stronger for boys. Examination of a model that included moderator effects revealed that the relation between peer pressure and drug use increased as a function of poor parenting. Results of our study underscore the importance of drug prevention efforts focused on parenting practices. 相似文献

The 'war' between religion and science is winding down, creating new opportunities for fruitful dialogue. The foundations of indirect religion-science dialogue, where the perspectives of the two disciplines illuminate some third subject, are not well established. A detailed comparison of the Roman Catholic bishops' dialogues and a similar program within the American Association for the Advancement of Science illustrates the variety in formalscience-religion interactions and reveals much about the promise, achievements, and limitations of different approaches. Success depends in large part on controlling the diversity of the dialogue group, choosing topics carefully, and adopting positive and cooperative attitudes. 相似文献

Testing joint attention, imitation, and play as infancy precursors to language and theory of mind 总被引:1,自引:0,他引:1

Various theoretical accounts propose that an important developmental relation exists between joint attention, play, and imitation abilities, and later theory of mind ability. However, very little direct empirical evidence supports these claims for putative “precursor” theory of mind status. A small sample (N=13) of infants, for whom measures of play, joint attention, and imitation had been collected at 20 months of age, was followed-up longitudinally at 44 months and a battery of theory of mind measures was conducted. Language and IQ were measured at both timepoints. Imitation ability at 20 months was longitudinally associated with expressive, but not receptive, language ability at 44 months. In contrast, only the joint attention behaviours of gaze switches between an adult and an active toy and looking to an adult during an ambiguous goal detection task at 20 months were longitudinally associated with theory of mind ability at 44 months. It is argued that joint attention, play, and imitation, and language and theory of mind, might form part of a shared social–communicative representational system in infancy that becomes increasingly specialised and differentiated as development progresses. 相似文献

Where does the supposed shame of older women's bodies come from? In this essay, I suggest that such shame is not a natural response to aging; rather, it is a culturally conditioned reaction to the patriarchal fantasy of female physical perfection. While certain norms and narratives within Christianity tacitly encourage women to pursue this fantasy, there are also resources within this tradition that can help us challenge the stigma assigned to older female flesh and affirm the goodness of bodies that have lived a long time. Simultaneously, aging itself can provide a lens for fruitfully rethinking some central Christian ideas. 相似文献

Thousands of African American New Orleanians were displaced in the aftermath of Hurricane Katrina. It appeared that every African American suddenly became a suspect, “fair game” to be hunted, especially by the police. This autoethnography chronicles the author's personal background, experiences, and resulting emotions of her father's encounter with law enforcement post–Hurricane Katrina. Law enforcement–initiated interventions are explored. The article concludes with recommendations for members of the counseling profession and law enforcement. Miles de personas afroamericanas de Nueva Orleans perdieron sus hogares como consecuencia del huracán Katrina. Y de repente, cada persona afroamericana pareció convertirse en sospechosa, “presa legítima” para la caza, especialmente por parte de la policía. Esta autoetnografía documenta los orígenes personales y experiencias de la autora, así como las emociones resultantes de la interacción de su padre con las fuerzas policiales tras el huracán Katrina. Se exploran las intervenciones iniciadas por las fuerzas policiales. El artículo concluye con una serie de recomendaciones para los profesionales de la consejería y las fuerzas policiales. 相似文献

Road Sign Detection and Recognition (RSDR) is aimed to enable drivers maintain basic functionality with the aim of identifying and notifying driver through the existing restrictions so that the process is a success on the present widened road. Examples for RSDR include ‘traffic light ahead’ or ‘pedestrian crossing’ signs. An innovative RSDR system has been introduced which comprises of pre-processing, edge detection, feature extraction, features selection and Ensemble Fuzzy Support Vector Machine (EFSVM) classifier. Feature selection is carried out successfully by deployment of Ant Colony Optimization (ACO) algorithm to determine most prominent and definitive features. These features are then fed into the ensemble SVM to enable both road side traffic detection as well as recognition. Suggested system’s performance is analyzed and evaluated with respect to road signs having a capable recognition rate. 相似文献

Two eye-tracking experiments were conducted to compare the online reading and offline comprehension of main verb/reduced relative garden-path sentences and local coherence sentences. Rereading of early material in garden-path reduced relatives should be revisionary, aimed at reanalysing an earlier misparse; however, rereading of early material in a local coherence reduced relative need only be confirmatory, as the original parse of the earlier portion of these sentences is ultimately correct. Results of online and offline measures showed that local coherence structures elicited signals of reading disruption that arose earlier and lasted longer, and local coherence comprehension was also better than garden path comprehension. Few rereading measures in either sentence type were predicted by structural features of these sentences, nor was rereading related to comprehension accuracy, which was extremely low overall. Results are discussed with respect to selective reanalysis and good-enough processing. 相似文献
