The managers of beach businesses were randomly assigned to receive no intervention or two newsletters per week for 6 weeks that presented economic consequences of damage to coastal water quality and how to contact politicians. The percentage of proenvironmental political contacts was significantly greater in the experimental (newsletter) group than in the control group. Logistical regression showed that contacts in the newsletter group were more than five times that of controls after adjusting for history of contacts and predisposition to take such action. Results suggest that the intervention can promote political action that could influence environmental policies and human health.  相似文献

This paper summarizes a conference held at the National Institute of Child Health and Human Development on December 6-7, 1999, on self-injurious behavior [SIB] in developmental disabilities. Twenty-six of the top researchers in the U.S. from this field representing 13 different disciplines discussed environmental mechanisms, epidemiology, behavioral and pharmacological intervention strategies, neurochemical substrates, genetic syndromes in which SIB is a prominent behavioral phenotype, neurobiological and neurodevelopmental factors affecting SIB in humans as well as a variety of animal models of SIB. Findings over the last decade, especially new discoveries since 1995, were emphasized. SIB is a rapidly growing area of scientific interest to both basic and applied researchers. In many respects it is a model for the study of gene-brain-behavior relationships in developmental disabilities.  相似文献

Although much has been written about therapeutic interventions with caregivers, little is known about the counseling services that are available for victims of dementia. The present study was designed to explore community mental health center (CMHC) services and therapists' experiences in providing psychotherapy to this population in Massachusetts. Only 27 of the 36 CMHCs in the state reported providing mental health services to older adults with a dementing illness. A survey of therapists who specialized in working with older adults found that the percentage of older adult clients estimated to have dementia averaged about half of their caseload. Older persons in the early phase of a dementing illness were most frequently referred for depression and anxiety, whereas those with moderate decline were most frequently referred for management of disruptive behavior. The most common services provided to clients with dementia consisted of assessment and individual counseling. The latter finding indicates a discrepancy between what is practiced and the professional literature. Most of the psychotherapy described in the literature concerns group interventions, which were rarely provided by the mental health centers in Massachusetts. The centers tended to offer individual counseling; however, little information on how to provide this form of treatment can be found.  相似文献

This exploratory survey was an investigation of practitioner and practice characteristics of clinicians (N = 24) involved in the provision of equine-assisted mental health (EAMH) groups. We focused on practitioner education, credentialing, clinical experience, approach, and perceived self-efficacy, as well as specific group characteristics concerning type, duration, and clinical populations served. Results, limitations, and future directions are provided, with an overall aim of contributing to the development and progression of this increasingly used group approach.  相似文献

This study assessed the performance of the PC-PTSD in diagnosing postdeployment posttraumatic stress disorder (PTSD) in a cohort of Air Force Medical Services personnel (N = 18,530). The prevalence of PTSD in the cohort was 5.18% based on medical record data. The area under the receiver operating characteristic curve was 0.69, indicating poor classification accuracy. Sensitivity was 47.55%, specificity was 90.68%, positive predictive value was 21.79%, and negative predictive value was 96.94%. The positive and negative likelihood ratios were 5.10 and 0.58, respectively. Several risk factors were found to be associated with a diagnosis of postdeployment PTSD: being a nurse, being enlisted in the medical service career field, being enlisted in the mental health service career field, those over age 30, being a member of the Active Duty service component, and having one’s first deployment be to Iraq. Being an officer was found to be a protective characteristic. These factors could potentially improve screening for PTSD among Air Force healthcare personnel.  相似文献

Why should all human beings have certain rights simply by virtue of being human? One justification is an appeal to religious authority. However, in increasingly secular societies this approach has its limits. An alternative answer is that human rights are justified through human dignity. This paper argues that human rights and human dignity are better separated for three reasons. First, the justification paradox: the concept of human dignity does not solve the justification problem for human rights but rather aggravates it in secular societies. Second, the Kantian cul-de-sac: if human rights were based on Kant’s concept of dignity rather than theist grounds, such rights would lose their universal validity. Third, hazard by association: human dignity is nowadays more controversial than the concept of human rights, especially given unresolved tensions between aspirational dignity and inviolable dignity. In conclusion, proponents of universal human rights will fare better with alternative frameworks to justify human rights rather than relying on the concept of dignity.  相似文献

Loneliness concerns the subjective evaluation that the number of relationships is smaller than the individual considers desirable or that the intimacy that the individual wishes for has not been realized. The aim of this study was to assess variations in levels of late-life loneliness and its determinants across Europe. Data came from the SHARE surveys, Wave 2 (Borsch-Supan et al., 2008), encompassing adults aged 50 years and over in Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Ireland, Italy, the Netherlands, Poland, Spain, Sweden, and Switzerland (N = 12,248). Loneliness was measured by a single item derived from the CES-D (depression) scale. Using logistic models, the present authors tested several types of explanations for country differences: differences in demographic characteristics, wealth and health, and social networks. Older adults in the southern and central European countries were generally lonelier than their peers in the northern and western European countries. In the southern and central European countries, loneliness was largely attributable to not being married, economic deprivation, and poor health. Frequent contacts with parents and adult children, social participation, and providing support to family members were important in preventing and alleviating loneliness in almost all countries. To combat loneliness among older adults, the findings suggest both (a) generic approaches aimed at improving social embeddedness and (b) country-tailored approaches aimed at improving health and wealth.  相似文献

Purpose

The purpose of this study was to develop and test a model relating proactive personality to job behaviors (task and citizenship behaviors) through the intervening mediator of perceived role breadth.

Design/methodology/approach

Survey data were obtained from 530 faculty members in 69 U. S. research universities.

Findings

Proactive personality was positively related to task behavior and OCB. Perceived role breadth mediated the relationship between proactive personality and OCB, but did not mediate the relationship between proactive personality and task behavior. Despite not viewing their role more broadly, individuals higher in proactive personality engaged more frequently in both task behavior and OCB; and also worked more hours per week.

Implications

Having a better understanding of proactive individuals is important in terms of managing them. Because these individuals tend to do more in their jobs and subsequently work more hours, they may be more susceptible to burnout and may require additional help in determining priorities and balancing their work and lives.

Originality/value

This is the first study to show that proactive personality is positively related to the frequency with which these individuals engage in task and citizenship behavior. Although role breadth is generally an antecedent of such job behaviors, individuals higher in proactive personality engage more frequently in task behaviors regardless of whether or not they perceive them as part of their role. This is one of the first studies to show that working more hours each week is a potential cost of having a proactive personality.  相似文献

Implicit associations can interfere with cognitive operations and behavioral decisions without direct intention. Enhancement of neural activity with anodal transcranial direct current stimulation (tDCS) was proposed to reduce implicit associations by means of improved cognitive control. However, a targeted reduction of distractive implicit associations by inhibitory cathodal tDCS, recently shown in spatial–numerical associations, provides an interesting alternative approach to support goal-directed behavior with transcranial brain stimulation. To test this rationale with a sham-controlled cross-over design, a standardized Implicit Association Test (IAT) was performed by 24 healthy participants parallel to 1 mA cathodal or sham tDCS to the left prefrontal cortex. In this double-classification task, insect versus flower pictures and negative versus positive words are mapped together onto two shared response keys with crossed response assignments in separate blocks. Responses were faster when insect + negative and flower + positive stimuli required the same answer (IAT effect). Most critically, the IAT effect was reduced during cathodal tDCS as compared to sham stimulation. Thus, results are consistent with the proposed stimulation rationale, with previous observations, and complementary to previous studies using different tDCS configurations.  相似文献
