Aboriginal youth are highly overrepresented within the child welfare system. High-risk youth are often placed in out-of-community residential placements. Such residential placements have been described by some as a continuation of colonial practices. Using communication theory as a conceptual model, we propose a qualitative analysis of micro-interactions that take place between Aboriginal youth and non-Aboriginal workers during the management of high-risk behaviors within a residential program. Three broad categories of interaction emerge from the data: complementary, symmetrical/complementary (where youth show a form of submission despite resistance), and symmetrical (characterized by a power struggle). Despite the diversity of interactions along this symmetrical to complementary continuum, interventions always start and finish in the same fashion. Moreover, the nature of interactions depended mostly on how quickly youth accepted the consequences of their behaviors. We also extracted five categories related to culture, race or context that are perceived as influencing the interactions that take place between staff and youth. The analysis of micro-interactions within clinical, organizational, social and historical contexts points to mechanisms by which asymmetrical power relations may be replicated on a day-to-day basis despite the best intentions of residential workers.  相似文献

Previous research has shown that focus of attention affects movement economy in endurance tasks. This experimental study was designed to take a closer look at how focusing attention on special characteristics of endurance cycling actions can influence metabolic energy costs. Twenty-five trained cyclists completed 4 × 6 min time trials at submaximal intensity on a cycling ergometer. For each of the four time trials, they were instructed to adopt a different focus of attention: (1) circular pedaling, (2) force production of quad muscles, (3) head position, (4) stimuli in a cycling video. The order of conditions was counterbalanced. The main dependent measure was movement economy (i.e., oxygen consumption at a given workload). The results show that a focus on the circular pedaling action leads to reduced economy than a focus on the video (p = 0.001). Focusing on smooth and circular pedaling includes a continuous monitoring of the cycling action, which could disturb the rhythmical nature of movement execution, thereby leading to detriments in movement economy.  相似文献

There is a need for improved normative information in particular for older persons. The present study provides neuropsychological test norms on seven cognitive tests used in a sample representing the general older driving population, when uncontrolled and controlled for physical health. A group of 463 healthy Swedish car drivers, aged 65 to 84 years, participated in a medical and neuropsychological examination. The latter included tests of visual scanning, mental shifting, visual spatial function, memory, reaction time, selective attention, and simultaneous capacity. Hierarchical regression analyses demonstrated that, when uncontrolled for health, old age was associated with significant impairment on all seven tests. Education was associated with a significant advantage for all tests except most reaction time subtests. Women outperformed men on selective attention. Controlling for health did not consistently change the associations with education, but generally weakened those with age, indicating rises in normative scores of up to 0.36 SD (residual). In terms of variance explained, impaired health predicted on average 2.5%, age 2.9%, education 2.1% and gender 0.1%. It was concluded (1) that individual regression‐based predictions of expected values have the advantage of allowing control for the impact of health on normative scores in addition to the adjustment for various demographic and performance‐related variables and (2) that health‐adjusted norms have the potential to classify functional status more accurately, to the extent that these norms diverge from norms uncontrolled for physical health.  相似文献

Research has shown that self‐efficacy is often one of the most important personal resources in the work context. However, because this research has focused on cognitive and task‐oriented self‐efficacy, little is known about social and emotional dimensions of self‐efficacy at work. The main aim of the present study was to investigate social and emotional self‐efficacy dimensions at work and to compare them to a cognitive and task‐oriented dimension. Scales to measure social and emotional self‐efficacy at work were developed and validated and found to be well differentiated from the cognitive task‐oriented occupational self‐efficacy scale. Confirmatory factor analyses of data from 226 Swedish and 591 German employees resulted in four separate but correlated self‐efficacy dimensions: (1) occupational; (2) social; (3) self‐oriented emotional; and (4) other‐oriented emotional. Social self‐efficacy explained additional variance in team climate and emotional self‐efficacy in emotional irritation and emotional exhaustion, over and above effects of occupational self‐efficacy. Men reported higher occupational self‐efficacy, whereas social and emotional self‐efficacy revealed no clear gender differences. The scales have strong psychometric properties in both Swedish and German language versions. The positive association between social self‐efficacy and team climate, and the negative relationships between self‐oriented emotional self‐efficacy and emotional irritation and emotional exhaustion may provide promising tools for practical applications in work settings such as team‐building, staff development, recruitment or other training programs aiming for work place health promotion. The next step will be to study how social and emotional self‐efficacy relate to leadership, well‐being and health over time.  相似文献

Young Black gay/bisexual men (YBGBM) are affected by contextual stressors—namely syndemic conditions and minority stress—that threaten their health and well‐being. Resilience is a process through which YBGBM achieve positive psychosocial outcomes in the face of adverse conditions. Self‐efficacy, hardiness and adaptive coping, and social support may be important resilience factors for YBGBM. This study explores different profiles of these resilience factors in 228 YBGBM in New York City and compares profiles on psychological distress, mental health, and other psychosocial factors. Four profiles of resilience were identified: (a) Low self‐efficacy and hardiness/adaptive coping (23.5%); (b) Low peer and parental support (21.2%); (c) High peer support, low father support (34.5%); and (d) High father and mother support, self‐efficacy, and hardiness/adaptive coping (20.8%). YBGBM in profile 1 scored markedly higher on distress (= .74) and lower on mental health functioning (= .93) compared to men in the other profiles. Results suggest that self‐efficacy and hardiness/adaptive coping may play a more important role in protecting YBGBM from risks compared to social support and should be targeted in interventions. The findings show that resilience is a multidimensional construct and support the notion that there are different patterns of resilience among YBGBM.  相似文献

We examine the (in)compatibility of diversity and sense of community by means of agent‐based models based on the well‐known Schelling model of residential segregation and Axelrod model of cultural dissemination. We find that diversity and highly clustered social networks, on the assumptions of social tie formation based on spatial proximity and homophily, are incompatible when agent features are immutable, and this holds even for multiple independent features. We include both mutable and immutable features into a model that integrates Schelling and Axelrod models, and we find that even for multiple independent features, diversity and highly clustered social networks can be incompatible on the assumptions of social tie formation based on spatial proximity and homophily. However, this incompatibility breaks down when cultural diversity can be sufficiently large, at which point diversity and clustering need not be negatively correlated. This implies that segregation based on immutable characteristics such as race can possibly be overcome by sufficient similarity on mutable characteristics based on culture, which are subject to a process of social influence, provided a sufficiently large “scope of cultural possibilities” exists.  相似文献

This study examined the relationship between traditional masculine role norms (status, toughness, anti‐femininity) and psychosocial mechanisms of sexual risk (sexual communication, sexual self‐efficacy) among young, low‐income, and minority parenting couples. Between 2007 and 2011, 296 pregnant adolescent females and their male partners were recruited from urban obstetrics clinics in Connecticut. Data regarding participants' beliefs in masculine role norms, frequency of general sex communication and sexual risk communication, and sexual self‐efficacy were collected via computer‐assisted self‐interviews. Generalized estimating equation (GEE) models were used to test for actor effects (whether a person's masculine role norms at baseline influence the person's own psychosocial variables at 6‐month follow‐up) and partner effects (whether a partner's masculine role norms at baseline influence an actor's psychosocial variables at 6‐month follow‐up). Results revealed that higher actor status norms were significantly associated with more sexual self‐efficacy, higher actor toughness norms were associated with less sexual self‐efficacy, and higher actor anti‐femininity norms were significantly associated with less general sex communication, sexual risk communication, and sexual self‐efficacy. No partner effects were found. These results indicate a need for redefining masculine role norms through family centered approaches in pregnant or parenting adolescent couples to increase sexual communication and sexual self‐efficacy. Further research is needed to understand partner effects in the context of a relationship and on subsequent sexual risk behavior.  相似文献
