This article describes the scope of the current school drop-out problem. Within this context, an overview and analysis of the school drop-out problem among the Florida Seminole is provided. Current prevention and remediation strategies for populations at risk are reviewed. Culturally sensitive strategies are suggested for addressing this Seminole problem.  相似文献

A large national sample of high school seniors rated their preferences for the allocation of work and family duties within their own prospective marriages. The results indicate that many seniors favor half-time or full-time work for wives without children. On the other hand, the majority prefer that the mother of preschool children stay home, although half-time work is acceptable to many. Respondents who are male or White or did not have a working mother themselves are somewhat more conservative on these issues. Virtually all seniors view less than full-time employment by the husband as unacceptable. With regard to child care and housework, most seniors prefer equal sharing between the spouses. A comparison of four senior classes reveals a slight trend from 1976 to 1979 toward increased sharing of duties.  相似文献

When presented with a choice between 1 and 3 pieces of food in a type of reversed contingency task, 4 cotton-top tamarins (Saguinus oedipus) consistently chose the 3 pieces of food and received nothing, even though the choice of 1 piece would have yielded 3. However, in a task in which the tamarins received the 1 piece of food when they chose it, all subjects learned to select 1 over 3. Thus, the tamarins' prior failure on the reversed contingency task did not result entirely from an inherent inability to suppress the prepotent response of reaching to the larger of 2 quantities of food. After the experience of selecting the smaller quantity and receiving it, all of the tamarins solved the version of the reversed contingency task that they failed initially. These results suggest that the tamarins' initial failure may have reflected a difficulty with selecting an alternative response option.  相似文献

Abstracting generalities from concrete experience allows the application of acquired knowledge to novel situations, a hallmark of primate cognition. Abstraction may also enable some animals to overcome prepotent biases, by allowing them to treat prepotent stimuli and responses more flexibly. The aim of the current study was to determine whether rhesus macaques (Macaca mulatta) could generalize successful performance on an executive control task with one training exemplar to novel exemplars. Three monkeys learned a reverse-reward task in which they chose between one and four food items. They had to select the smaller quantity to receive the larger one, and so had to inhibit the prepotent selection of the larger quantity. After they learned the task, a transfer test assessed whether they had learned only about the quantities experienced or whether they could generalize to novel quantities. All three rhesus monkeys spontaneously generalized to novel quantities, showing that this species has the ability to generalize significantly beyond the immediate perceptual experience and use this ability to control lower-level, prepotent responses.  相似文献

Twin and family studies have shown that genetic factors play a role in the development of conduct disorder (CD). The purpose of this study was to identify genetic variants associated with CD using a family-based association study. We used 4,720 single nucleotide polymorphisms (SNPs) from the Illumina Panel and 11,120 SNPs from the Affymetrix 10K GeneChips genotyped in 155 Caucasian nuclear families from Genetic Analysis Workshop (GAW) 14, a subset from the Collaborative Study on the Genetics of Alcoholism (COGA). 20 SNPs had suggestive associations with CD (p < 10−3), nine of which were located in known genes, including ADAM10 (rs383902, p = 0.00036) and CAMK2A (rs2053053, p = 0.00098). Our results were verified using the International Multi-Center ADHD Genetics Project (IMAGE) dataset. In conclusion, we identified several loci associated with CD. Especially, the two genes (ADAM10 and CAMK2A) have been reported to be associated with Alzheimer’s disease, bipolar disorder and depression. These findings may serve as a resource for replication in other populations.  相似文献

Self-reports of insomnia were collected among 467 nurses working at 4 hospitals. At 2 of these hospitals, a change in pay policy resulted in reduced pay for all nurses, whereas nurses' pay was unchanged at the other 2 hospitals. Nursing supervisors at 1 hospital in each group received training in promoting interactional justice, whereas no training was provided at the other 2 hospitals. Reflecting the stressful nature of underpayment, insomnia was significantly greater among nurses whose pay was reduced than among those whose pay remained unchanged. However, the degree of insomnia was significantly lower among nurses whose supervisors were trained in interactional justice, both immediately after training and 6 months later. These findings demonstrate the buffering effects of interactionally fair treatment on reactions to underpayment.  相似文献
