The relationship between the state and religious schools in North America has been an uneven and unsettled one, punctuated at times with abusive behavior by the state. The purpose of this article is to present a historical overview of this important and changing relationship, and to provide a conceptual framework for understanding religious schools in a society with a governmental-school ethos.  相似文献

MTV’s hit programs 16 and Pregnant and Teen Mom have been the subject of national debate since their inception. Supporters contend that the shows inhibit pregnancy-risk behavior. Critics contend that the shows glamorize adolescent motherhood and encourage pregnancy-risk behavior. The present study explored the possibility that the association between viewing 16 and Pregnant and Teen Mom and student females’ pregnancy-risk behavior depends on the extent to which females’ parents communicated with them about sex while they were growing up. Survey data were gathered from 313 female students. A disordinal interaction was found between father–daughter sexual communication, viewing frequency, and recent intercourse behavior. Frequent viewing was associated with an increased probability of having engaged in recent intercourse for females whose fathers did not communicate with them about sex while growing up. Conversely, frequent viewing was associated with a decreased probability of having engaged in recent intercourse for females whose fathers often communicated about sex with them while growing up. No interaction was found between mother–daughter sexual communication, viewing frequency, and recent intercourse behavior. These results suggest that fathers may play an especially important role in determining how sexual media socialize their daughters.  相似文献

Understanding work ability, with the goal of promoting it, is important for individuals as well as organizations. It is especially important to study work ability in health care workers, who face many work-related challenges that may threaten work ability. We studied various job demands, job resources, and interactions of demands and resources relating to work ability using the Job Demands–Resources model as a framework. Acute care health care workers from six nations (US, Australia, UK, Brazil, Croatia, and Poland) completed a survey. Role demands related to work ability in the Australia sample only, and supervisor support related to work ability in the Australia sample only. Yet, high levels of supervisor support significantly moderated (buffered) negative relationships between physical demands and work ability in the US sample, along with negative relationships between role demands and work ability in both the Croatia and UK samples. Skill discretion related to work ability in every nation sample, and therefore appears to be particularly important to work ability perceptions. In addition, skill discretion moderated (buffered) a negative relationship between role demands and work ability in the Australia sample. We therefore recommend that interventions to help preserve or improve work ability target this important job resource.  相似文献

ABSTRACT

The hypercorrection effect, which refers to the finding that errors committed with high confidence are more likely to be corrected than are low confidence errors, has been replicated many times, and with both young adults and children. In the present study, we contrasted older with younger adults. Participants answered general-information questions, made confidence ratings about their answers, were given corrective feedback, and then were retested on questions that they had gotten wrong. While younger adults showed the hypercorrection effect, older adults, despite higher overall accuracy on the general-information questions and excellent basic metacognitive ability, showed a diminished hypercorrection effect. Indeed, the correspondence between their confidence in their errors and the probability of correction was not significantly greater than zero, showing, for the first time, that a particular participant population is selectively impaired on this error correction task. These results potentially offer leverage both on the mechanisms underlying the hypercorrection effect and on reasons for older adults’ memory impairments, as well as on memory functions that are spared.  相似文献

“Success” in dieting interventions has traditionally been defined as weight loss. It is implicit in this definition that losing weight will lead to improved health, and yet, health outcomes are not routinely included in studies of diets. In this article, we evaluate whether weight loss improves health by reviewing health outcomes of long‐term randomized controlled diet studies. We examine whether weight‐loss diets lead to improved cholesterol, triglycerides, systolic and diastolic blood pressure, and fasting blood glucose and test whether the amount of weight lost is predictive of these health outcomes. Across all studies, there were minimal improvements in these health outcomes, and none of these correlated with weight change. A few positive effects emerged, however, for hypertension and diabetes medication use and diabetes and stroke incidence. We conclude by discussing factors that potentially confound the relationship between weight loss and health outcomes, such as increased exercise, healthier eating, and engagement with the health care system, and we provide suggestions for future research.  相似文献

The complementary learning systems framework provides a simple set of principles, derived from converging biological, psychological and computational constraints, for understanding the differential contributions of the neocortex and hippocampus to learning and memory. The central principles are that the neocortex has a low learning rate and uses overlapping distributed representations to extract the general statistical structure of the environment, whereas the hippocampus learns rapidly using separated representations to encode the details of specific events while minimizing interference. In recent years, we have instantiated these principles in working computational models, and have used these models to address human and animal learning and memory findings, across a wide range of domains and paradigms. Here, we review a few representative applications of our models, focusing on two domains: recognition memory and animal learning in the fear-conditioning paradigm. In both domains, the models have generated novel predictions that have been tested and confirmed.  相似文献

The study investigates the hypothesis that children's ability to attribute second-order beliefs facilitates their understanding of evidence, as seen in the ability to distinguish between causes and reasons. Seventy-four children 5–7 yr old were given belief and evidence tests. The belief tests assessed their ability to represent and reason from second-order false-beliefs, and the evidence tests assessed their ability to distinguish between the cause of a situation and a person's reason for believing it. The relation between performance on the two tests was determined, taking into account general language and non-verbal reasoning abilities. Results show that performance on the belief test and on the evidence part of the evidence test improved significantly over the age range, and that a significant proportion of variance in the evidence test scores is accounted for by second-order false-belief understanding, over and above that accounted for by general language and non-verbal abilities. The argument is made that second-order false-belief understanding is fundamental to children's epistemological development, underlying not just their understanding of evidence, but also their understanding of inference and truth.  相似文献

Cinematherapy involves assigning clients commercial movies to view between sessions of therapy. This article describes the applications of cinematherapy as a useful adjunct to more traditional approaches to therapeutic change. Techniques for implementation are outlined, and potential advantages of the use of cinematherapy are discussed. While cinematherapy may be used as an assignment within a variety of theoretical orientations, this article conceptualizes the technique from the perspective of the use of metaphor to promote therapeutic change. Although many therapists report informal use of films in working with clients, there is a paucity of research on the efficacy of cinematherapy as a counselling technique. The article makes extrapolations about effectiveness based on empirical findings involving use of the related technique of bibliotherapy. However, the authors hope that the article will inspire more formal research into the use of cinematherapy.  相似文献
