Advocates perform an important role in representing the rights of mental health consumers, especially since mental health consumers are often marginalized. Little is known about the processes advocates use to assist mental health consumers in navigating the health care system. This study details the manner in which advocates work together with mental health consumers and health professionals through presenting a qualitative synthesis of 60 case records. Four main themes emerged: negotiating on behalf of consumers during meetings with health professionals; liaising between consumers and health professionals outside of meetings; supporting consumer decision making without the involvement of health professionals; and involvement in legal processes. The findings of this study demonstrated that advocates were primarily oriented toward the protection of negative rights, but they also promoted positive rights.  相似文献

One of teenagers’ key developmental tasks is to engage in new and meaningful relationships with peers and adults outside the family context. Attachment-derived expectations about the self and others in terms of internal attachment working models have the potential to shape such social reorientation processes critically and thereby influence adolescents’ social-emotional development and social integration. Because the neural underpinnings of this developmental task remain largely unknown, we sought to investigate them by functional magnetic resonance imaging. We asked n = 44 adolescents (ages 12.01–18.84 years) to evaluate positive and negative adjectives regarding either themselves or a close other during an adapted version of the well-established self-other trait-evaluation task. As measures of attachment, we obtained scores reflecting participants’ positive versus negative attachment-derived self- and other-models by means of the Relationship Questionnaire. We controlled for possible confounding factors by also obtaining scores reflecting internalizing/externalizing problems, schizotypy, and borderline symptomatology. Our results revealed that participants with a more negative attachment-derived self-model showed increased brain activity during positive and negative adjective evaluation regarding the self, but decreased brain activity during negative adjective evaluation regarding a close other, in bilateral amygdala/parahippocampus, bilateral anterior temporal pole/anterior superior temporal gyrus, and left dorsolateral prefrontal cortex. These findings suggest that a low positivity of the self-concept characteristic for the attachment anxiety dimension may influence neural information processing, but in opposite directions when it comes to self- versus (close) other-representations. We discuss our results in the framework of attachment theory and regarding their implications especially for adolescent social-emotional development and social integration.  相似文献

Ethical climate in organisations has been studied widely and its influence on ethical behaviour has been documented. However, little is known about the ethical climate at university context and about its antecedents. Universities are social change institutions and their ethical climate could influence the ethical behaviour of future economic, social and political leaders. The current study analyses the perceived ethical climate in Business Studies Higher Education Institutions in Spain and whether university’s ownership, size and signing up for international initiatives influence it. The study is based on survey responses of 385 lecturers of Spanish Business Studies Faculties to an ethical climate questionnaire and on survey responses of 33 Business Studies Deans to a questionnaire related to the commitment to ethics and social responsibility in each Faculty. An exploratory factor analysis has been used as well as ANOVA tests and lineal regressions. The results reveal the predominance of an instrumental ethical climate in Spanish Business Faculties, an ethical climate that does not promote ethical behaviour or organisational commitment among its members. The results also confirm the significant influence of university’s ownership and signing up for Principles for Responsible Management Education on the ethical climate in Business Higher Education institutions. This study advances the understanding of the ethical climate in Business Studies institutions, and suggests measures to be taken by university managers in order to improve ethical judgment and behaviour of the university community.  相似文献

Impairments of word recognition in Alzheimer's disease (AD) have been less widely investigated than impairments affecting word retrieval and production. In particular, we know little about what makes individual words easier or harder for patients with AD to recognize. We used a lexical selection task in which participants were shown sets of four items, each set consisting of one word and three non‐words. The task was simply to point to the word on each trial. Forty patients with mild‐to‐moderate AD were significantly impaired on this task relative to matched controls who made very few errors. The number of patients with AD able to recognize each word correctly was predicted by the frequency, age of acquisition, and imageability of the words, but not by their length or number of orthographic neighbours. Patient Mini‐Mental State Examination and phonological fluency scores also predicted the number of words recognized. We propose that progressive degradation of central semantic representations in AD differentially affects the ability to recognize low‐imageability, low‐frequency, late‐acquired words, with the same factors affecting word recognition as affecting word retrieval.  相似文献

This article reconsiders the presence and value of danger in outdoor and adventurous activities and sports in safety-conscious societies, especially in relation to the education of children and youth. Based on an original analysis of the relation between the concepts of ‘risk’ and ‘danger’, we offer an account of the relation between challenge, adventure, risk and danger, and emphasise the importance of teaching risk recognition, risk assessment, risk management and risk avoidance to children and youth, without the necessity of exposing them to jeopardy in dangerous situations. Our conclusion is that ‘Safe Danger’ describes what educators should seek, namely: the educational benefits of the challenges set by risk-taking and the demands of risk-facing, including those in adventurous situations, which are obtainable in the absence of significant danger, and which contribute to risk education. The educational value of adventurous and outdoor pursuits lies elsewhere than in the opportunities that they present for danger-facing, for example in their promotion of self-reliance, confidence, ability to team-work, and especially in their promotion of risk education, as an integral aspect of everyday life planning, as preparation for the day’s adventurous challenges, and as an instrument of task completion.  相似文献

Background/Objective: The Dual Control Model suggests that sexual excitation and associated behaviors are the result of the balance between relatively independent excitatory and inhibitory mechanisms. Based on this theoretical model, the Sexual Excitation/Sexual Inhibition Inventory for Women (SESII-W) was developed to evaluate excitation and inhibition dimensions in women. The aim was to adapt and validate the SESII-W in the Spanish population. Method: A sample of 1,380 heterosexual women (aged 18 to 52) completed the Spanish SESII-W, together with other related instruments. After the translation and adaptation of the SESII-W, a Confirmatory Factor Analysis (CFA) was performed. Results: CFA resulted in a version consisting of 33 items divided into eight sub-factors, which were grouped into two higher-order factors (Sexual Excitation and Sexual Inhibition). The sub-factors demonstrated adequate internal consistency values except for Sexual Power Dynamics and Concerns about Sexual Function. Test-retest reliabilities were good. Their scores correlated with erotophilia, sexual sensation seeking, age at first intercourse, and number of sexual partners in the expected direction. Conclusions: The Spanish version of SESII-W has adequate psychometric guarantees for use in clinical practice and research, although it would be necessary to further revise factors that showed a lower level of reliability.  相似文献

When asked to translate utterances, people might merely make sure that their translations have the same meaning as the source, but they might also maintain aspects of sentence form across languages. We report two experiments in which English–German and German–English bilinguals (without specialist translator training) repeated German ditransitive sentences whose meaning was compatible with more than one grammatical form or translated them into English. Participants almost invariably repeated the sentences accurately, thereby retaining the grammatical structure. Importantly, Experiment 1 found that they tended to repeat grammatical form across languages. Experiment 2 included a condition with sentences that had no grammatical equivalent form in English; here participants tended to persist in the order of thematic roles. We argue that cross-linguistic structural priming plays a major role in the act of translation.  相似文献

The aim of this study was to explore children’s understanding of depreciation when being presented with scenarios of envious or modest behavior. 123 Spanish children, six to eight years of age, decided how a character should respond when faced with a situation of envy or modesty. These situations were described in vignettes. The children chose between a response of either depreciation or admiration in the case of envy and between a response of either modesty or immodesty when faced with modest behavior. They were then asked to explain the reasons for their choices. Generally speaking, the results indicated that children rated self-depreciation in scenarios of modesty more highly than they did depreciation of another in situations of envy. An interaction effect showed that eight-year-old chose modest responses more than immodest ones, in contrast to the six-year-old. Conversely, age differences were not observed for the scenarios of envy. We discuss these results in light of the children’s explanations. Furthermore, the acquisition of emotional display rules is discussed, as well as the ability to manage emotions. Also, we discuss the truths and falsehoods of expression within the framework of social pragmatism in the selection of responses in both scenarios.  相似文献
