Increasing evidence indicates the importance of environmental variables in explaining physical activity. This study evaluated sex differences in perception of home and neighborhood environmental support and assessed which neighborhood environmental variables were associated with reported physical activity of elderly people. A sample of 126 women (M age = 79.1 +/- 6.6 yr.) and 55 men (M age = 76.6 +/- 7.7 yr.) were healthy, community-dwelling individuals. A questionnaire about environmental variables was administered. Physical activity was assessed on the Baecke Questionnaire. Logistic regression analysis showed that Neighborhood Safety was related to total physical activity, activity in leisure time, and sport activities. Men were also likely to be more active in leisure time than women. Neighborhood Personal Safety was associated with physical activity of these elderly people, showing a potential influence of the environmental domain in physical activity. 相似文献

Noradrenergic control of odor recognition in a nonassociative olfactory learning task in the mouse 下载免费PDF全文

The present study examined the influence of pharmacological modulations of the locus coeruleus noradrenergic system on odor recognition in the mouse. Mice exposed to a nonrewarded olfactory stimulation (training) were able to memorize this odor and to discriminate it from a new odor in a recall test performed 15 min later. At longer delays (30 or 60 min), the familiar odor was no longer retained, and both stimuli were perceived as new ones. Following a post-training injection of the alpha(2)-adrenoceptor antagonist dexefaroxan, the familiar odor was still remembered 30 min after training. In contrast, both the alpha(2)-adrenoceptor agonist UK 14304 and the noradrenergic neurotoxin DSP-4 prevented the recognition of the familiar odor 15 min after the first exposure. Noradrenaline release in the olfactory bulb, assessed by measurement of the extracellular noradrenaline metabolite normetanephrine, was increased by 62% following dexefaroxan injection, and was decreased by 38%-44% after treatment with UK 14304 and DSP-4. Performance of mice in the recall test was reduced by a post-training injection of the beta-adrenoceptor antagonist propranolol or the alpha(1)-antagonist prazosin, thus implicating a role for beta- and alpha(1)-adrenoceptors in the facilitating effects of noradrenaline on short-term olfactory recognition in this model. 相似文献

The MacArthur-Bates Inventories are a valid and reliable method for assessing communicative and linguistic skills in infants (8-15 months) and young children (16-30 months), and have been adapted to many languages. This paper presents their adaptation to Spanish. Structure, innovations included in the Spanish version, and the standardisation process are described, and some results obtained from the analysis of a sample of 1150 children are presented. The advantages and limitations of the use of parental report inventories are highlighted. For children before three years of age, there are very few assessment tools of language and communicative development with sufficient guarantees produced and edited in Spain. The Spanish version of the MacArthur-Bates Inventories represents an important contribution for early identification of language delays or disorders, and for follow-up of these cases. 相似文献

Metcalf and Dimidjian (this issue) have provided an important review of the current evidence base for mindfulness‐based cognitive therapy (MBCT) and presented a helpful summary of the proposed mechanisms of change. It is necessary to engage in a continuous dialogue regarding the evidence base for change mechanisms, and the article by Metcalf and Dimidjian highlights an important barrier of concern to the field of treatment outcome research. The present commentary aims to expand the discussion regarding the definition, measurement, and evaluation of “mechanisms of change.” Using MBCT as an example, this commentary addresses the ambiguity surrounding the definition and operationalisation of these mechanisms in research on psychological therapies and how the method of measurement may impact the results obtained in clinical trials. It is argued that a potentially fruitful avenue of future research would involve investigation of techniques, important client‐therapeutic processes, and mechanisms in a single study in order to comprehensively evaluate how change occurs. 相似文献

In Europe there is no common quality assurance framework for the delivery of guidance in higher education. Using a case study approach in four university career guidance services in England, France and Spain, this article aims to study how quality is implemented in university career guidance services in terms of strategy, standards and models, relationship with main stakeholders and quality assessment. The case study findings reveal that the services articulate their strategy and mission as dedication to providing a quality service. However, little objective assessment of programmes and procedures is actually being conducted. 相似文献

A fundamental model of stereotypes, the stereotype content model (SCM, Fiske et al. 2002), postulates that stereotypes of many social groups vary on two core dimensions: warmth and competence. In line with traditional gender stereotypes, the SCM predicts women to be perceived as warmer than men, and men to be perceived as more competent than women. Research on implicit measurement of stereotypes suggests that, next to people’s underlying beliefs, a major predictor is the tendency to favor one’s own group (Rudman et al. 2001). We examined gender stereotypes concerning warmth and competence, using implicit association tests (IATs, Greenwald et al. 1998) and drawing on diverse samples of women and men in eastern and western Germany (i.e., students and non-students; total N?=?384). On the warmth dimension, an overall women-warmth stereotype was found, confirming predictions of the SCM. On the competence dimension, associations of own gender and competence were observed for both men and women, suggesting the impact of self-favoring processes. Findings are discussed with respect to social role theory (Eagly 1987) and the changing roles of women. 相似文献
