The present study was designed to develop an innovative motivational intervention (based on Self-Determination Theory and Social Cognitive Theory) to increase physical activity (PA) in underserved adolescents. Sixty-four adolescents (35 females, 29 males; 50% minority; 65% on reduced lunch program; ages 11-13 yr) participated in either an 8-week motivational intervention after-school (n = 32) or a typical after-school program (n = 32). The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Formative evaluation data was collected by staff through daily forms throughout the 8-week program and through observational data completed by independent objective observers during 2 weeks of the program. The major themes that were identified addressed theoretical concepts regarding the intervention and logistical issues in delivering the intervention. The data revealed information regarding the importance of the cognitive appropriateness of the PA and motivational activities, the environmental climate for promoting nurturing relationships, developing specific strategies for increasing intrinsic rather than extrinsic reinforcement, and developing methods for preventing social "cliques" and gender conflicts to maintain an appropriate level of support in the social climate. Themes for training staff included focusing on team building, leadership, and nurturing. This formative evaluation is being used to formalize a randomized trial to test the effects of a student-centered motivational intervention on increasing PA in underserved 6th graders. 相似文献

This paper is a case study of an attempt, using community developmentmethods, by local members of a state-local partnership to gainmore governance control in the face of central government dominance.The process highlighted in this case study was a community visioningexercise that built on existing networks at a local level todevelop the higher degree of active community involvement requiredto achieve more autonomy to meet felt community needs throughoutthe local district. The resources activated through the community development processenabled the partnership to successfully challenge central governmentdominance and develop local initiatives. It also raised issuesaround the autonomous development of mana whenua (the indigenouspeople of that place) initiatives and those of outlying ruralcommunities. The overall conclusion is one that supports a strategicapproach to local empowerment through the community developmentprocesses of enhancing local interactive multi-stakeholder networksand using leverage to negotiate change, in this case, by exploitingseemingly endemic structural weaknesses of the central government. 相似文献

In 2020, Australia's successful COVID-19 public health restrictions comprised a national “initial lockdown” (March–May) and “ongoing lockdown” (July–November) for metropolitan Victorian residents only. We evaluated associations between ongoing lockdown and family finances and mental health. In the June and September 2020 Royal Children's Hospital National Child Health Polls, caregivers of children in Victoria and New South Wales (NSW) reported the following: job/income loss; material deprivation (inability to pay for essential items); income poverty; mental health (Kessler-6); perceived impact on caregiver/child mental health; and caregiver/child coping. Data from caregivers (N = 1207/902) in June/September were analysed using difference-in-difference modelling (NSW provided the comparator). During Victoria's ongoing lockdown, job/income loss increased by 11% (95%CI: 3%–18%); Kessler-6 poor mental health by 6% (95%CI: −0.3%–12%) and perceived negative mental health impacts by 14% for caregivers (95%CI: 6%–23%) and 12% for children (95%CI: 4%–20%). Female (vs. male) caregivers, metropolitan (vs. regional/rural) families, and families with elementary school-aged children (vs. pre-/high-school) were the most affected. The ongoing lockdown was associated with negative experiences of mental health, employment and income, but not deprivation or poverty, likely because of government income supplements introduced early in the pandemic. Future lockdowns require planned responses to outbreaks and evidence-informed financial and mental health supports. 相似文献

Theories proposing climate change apathy is explained by inadequate knowledge do not account for why many informed and concerned Americans fail to act. While correlations between knowledge, efficacy for climate change, and attitude to mitigation have been observed, few studies have examined efficacy for climate change as a mediator. This study aimed to investigate the influence of specific climate change knowledge on attitude to mitigation via efficacy beliefs. A cross-sectional survey of 205 US adults recruited from Amazon's Mechanical Turk assessed participants’ climate change knowledge, efficacy for climate change, and attitude to mitigation. Indirect effects of self-efficacy for climate change were observed in three mediation models, suggesting efficacy for climate change explains some of the relationship between specific climate change knowledge and attitude to mitigation. The findings suggest risk communication can motivate pro-environmental attitudes with interventions that deliver information about climate change and develop efficacy for mitigation behavior. 相似文献

How do low socioeconomic status students navigate cross-class interactions in extremely unequal contexts? Previous research has described the high costs of college integration for underprivileged students, which in turn, negatively impact academic performance and general wellbeing. These studies tend to concentrate on cultural capital costs, such as catching up with assumed middle-class or elite capital and dealing with two worlds. Less has been said about social capital costs, the costs of making friends, especially more privileged friends. Through 61 in-depth interviews with various types of students as part of a broader ethnographic fieldwork, this article analyses the experiences of low-income scholarship holders in an elite institution in a very unequal society, Colombia. Rather than isolating themselves or resorting to safe homophilic relations, they faced their new elite environment engaging with the hidden relational cost of making friends with more affluent students. In so doing, they had to overcome fears and experiences of discrimination and micro-aggressions, as well as cultural and economic capital barriers, and employed either camouflaging or disclosure strategies, sometimes becoming culturally and socially omnivorous. Symbolic belonging to the institution and the acquisition of middle-class cultural capital were among the benefits that made overcoming the costs worthy. Our results shed light on what institutions can do to reduce the costs for underprivileged students and, theoretically, unveil an important mechanism and barrier for social mobility: building cross-class ties. 相似文献

News—or foresight—about future economic fundamentals can create rational expectations equilibria with non‐fundamental representations that pose substantial challenges to econometric efforts to recover the structural shocks to which economic agents react. Using tax policies as a leading example of foresight, simple theory makes transparent the economic behavior and information structures that generate non‐fundamental equilibria. Econometric analyses that fail to model foresight will obtain biased estimates of output multipliers for taxes; biases are quantitatively important when two canonical theoretical models are taken as data generating processes. Both the nature of equilibria and the inferences about the effects of anticipated tax changes hinge critically on hypothesized information flows. Different methods for extracting or hypothesizing the information flows are discussed and shown to be alternative techniques for resolving a non‐uniqueness problem endemic to moving average representations. 相似文献

Many observers are dissatisfied with the accounting profession's ability to warn the public of upcoming bankruptcy filings. Since regulators and users tend to treat an unmodified audit opinion as a “clean bill of health,” they do not expect the business to fail in the near future. Research has shown that more often than not, auditors end up letting users down when it comes to predicting bankruptcy filings with audit opinions. Although auditors assert they are not responsible for predicting future events, it is very clear that their opinion decision is evaluated, at least in part, based on events that occur after the audit report date. The interesting and logical next step is to find out how companies exit bankruptcy. Do they liquidate or reorganize? Successful reorganization may, in the end, exonerate auditors and preserve their role as an early warning device. The opinion prediction model developed in the paper introduces a new bankruptcy resolution variable that proxies for the auditor's prognosis of the ultimate disposition of the soon‐to‐be‐bankrupt company. Using a sample of bankruptcy filings between 1982 and 1992, we find that auditors do not seem to be able to predict filings or resolution. Our tests of bankruptcy resolution support what auditors have been arguing for years: that they are not clairvoyant with respect to a client's future. 相似文献

A variable-centered and a person-centered approach were performed to examine the role of early memories of warmth and safeness (EMWS) and current experiences of warmth and safeness (CEWS) on depressive and anxious symptoms among adolescents from community and residential youth care (RYC) settings. Variable-centered results revealed EMWS were only indirectly (through CEWS) associated with depressive and anxious symptoms. Person-centered outcomes allowed to identify four different profiles based on EMWS and CEWS, which differed on depressive and anxious symptoms. EMWS and CEWS seem to play an important role in psychological distress during adolescence. CEWS seem to have a protective role on RYC adolescents' psychological distress, even when EMWS were poor. 相似文献
