The regulated trafficking of GluR1 contributes significantly to synaptic plasticity, but studies addressing the function of the GluR1 C-terminal PDZ-ligand domain in this process have produced conflicting results. Here, we resolve this conflict by showing that apparently similar C-terminal mutations of the GluR1 PDZ-ligand domain result in opposite physiological phenotypes during activity- and CamKII-induced synaptic plasticity.  相似文献

While the Clinical Pastoral Education (CPE) method is usually employed in the health care setting and pointed toward the pastoral care of the sick, it can be adapted to the pastoral care and supervision of students doing ministry in the political, economic, and cultural systems of the rural community. In this article, the author, who speaks from thirty years of experience as a CPE supervisor in small towns in eastern South Dakota, describes his approach, an approach that emphasizes immersion in the general systems of struggling communities on the Great Plains. From his experience, he derives ten practical lessons that are applicable to CPE work in the rural context or in any pastoral setting.  相似文献

School psychologists are typically itinerant among multiple schools and often spend up to two-thirds of their time on assessment activities related to students with disabilities and special education programs. School psychologists in delivery of an expanded role service model are assigned to a single school and provide more consultation and intervention services. 97 school psychologists assigned to an expanded role in a single southeastern urban school district were surveyed on their job roles and job satisfaction. The majority were satisfied or very satisfied with their jobs, particularly with engaging in activities that were of service to others and staying involved in a variety of job activities. School psychologists wanted to spend less time in assessment, multidisciplinary team meetings, and administrative duties. The discrepancy between the desired and actual amount of time spent in multidisciplinary meetings was negatively related to job satisfaction. Psychologists wanted to spend more time in direct and indirect intervention, professional development, and networking.  相似文献

An ecological developmental model of adolescent suicidality was used to inform a hierarchical logistic regression analysis of longitudinal interactions between parent, peer, and school relations and suicide attempts. Reanalyzing data from the National Longitudinal Study of Adolescent Health, it was found that parent relations were the most consistent protective factor, and among boys with prior suicide attempts, school relations augmented the effects of parent relations when peer relations were low. Results indicated the need to understand suicidal behavior as a component of interactive social processes in the design of clinical interventions.  相似文献

The authors investigated the effect of mood on food selection. Participants (N = 98) indicated the likelihood of general eating and the likelihood of eating specific foods after reading and projecting themselves onto the events and emotions described in a sad and a happy vignette. Both men and women believed they were more likely to consume food following a happy versus a sad event, and men believed they were significantly more likely to eat than did women. However, the type of food men and women believed they would consume interacted with the type of event experienced. Vegetarian snack foods were more likely to be consumed following a happy versus a sad event, with men more likely to eat snack foods. Men did not significantly change in likelihood of consuming sweet foods as their mood changed. However, women believed they were more likely to consume sweet foods following a sad event. The authors discuss the results in terms of a self-medication hypothesis and the effect of carbohydrates on central serotonin and endogenous opioids. Overall, results demonstrated that mood influences belief in the likelihood of food selection.  相似文献

This study examined the impact of changes in level of current grief over time on changes in memory for past grief. Following from previous work on the impact of current affective state on memory for past affectively salient events, bereaved individuals who underwent a greater reduction in grief over time were expected to show a similar pattern of changes in memory for past grief. A sample of conjugally bereaved participants completed measures of current grief and memory for past grief at the time of the loss of their spouse at each of the 2, 6, 13, and 30 month post-loss time periods. As predicted, those who reported greater reduction in grief over the course of the study were more likely to remember their past grief as progressively less severe relative to those who underwent less reduction in grief over time. A nonrecursive causal model analysis verified that changes in memory for past grief were explained by changes in current grief. These results were discussed in terms of contemporary reconstructive memory accounts of the effect of affective state on memory.  相似文献

Sources of variability in children’s language growth   总被引:1,自引:0,他引:1  
The present longitudinal study examines the role of caregiver speech in language development, especially syntactic development, using 47 parent–child pairs of diverse SES background from 14 to 46 months. We assess the diversity (variety) of words and syntactic structures produced by caregivers and children. We use lagged correlations to examine language growth and its relation to caregiver speech. Results show substantial individual differences among children, and indicate that diversity of earlier caregiver speech significantly predicts corresponding diversity in later child speech. For vocabulary, earlier child speech also predicts later caregiver speech, suggesting mutual influence. However, for syntax, earlier child speech does not significantly predict later caregiver speech, suggesting a causal flow from caregiver to child. Finally, demographic factors, notably SES, are related to language growth, and are, at least partially, mediated by differences in caregiver speech, showing the pervasive influence of caregiver speech on language growth.  相似文献

The current study explored the relationship between religious coping and cumulative health risk associated with health behavior patterns in a sample of 256 Latina and Caucasian female caregivers of elderly relatives with dementia. Primary analyses examined the relationship between religious coping (both positive and negative) and an overall index of cumulative health risk. Secondary analyses were conducted on the individual health behaviors subsumed in the broader index. Findings revealed that negative religious coping was significantly associated with increased cumulative health risk. Positive religious coping was predictive of decreased cumulative health risk among Latina caregivers but not among Caucasians. Negative religious coping was significantly associated with both an increased likelihood for weight gain and increased dietary restriction. Positive religious coping was associated with decreased likelihood for weight gain in Latinas. Implications for both caregivers and clinicians are discussed.  相似文献

Ten years ago the UK held one of the largest, most complex and politically charged exercises in the turn towards public engagement in the governance of the biosciences. Called ‘GM Nation’ this experiment arose as an attempt to mediate public concerns in the run-up to a government decision on whether to allow some varieties of GM crops to be commercially cultivated in the UK. Formed to mediate a controversy, ‘GM Nation’ itself became a focus of controversy, with claims that many of its public participants were already engaged in the GM issue and were thus not representative of a general public. In this way, the category of the public became a contested category, with at least two different versions of the public featuring in the GM controversy. Particularly important was the contrast between engaged or issue publics that emerged entangled in and increasingly familiar with the objects and issues of the controversy, and a general public, identified through its distance and disengagement from the GM issue. These different forms of public were articulated through different modes of engagement ranging from engaged publics found in hybrid forums such as local village meetings, to versions of the general public brought into being in some of the closed parts of ‘GM Nation’. Throughout all this, a wider public institutional architecture, improvised to govern the controversy, became the site of complex boundary work that attempted to separate science from politics, a feature that conditioned how these different versions of public would be articulated and received.  相似文献
