Objective: The purpose of this pilot study was to evaluate the Resilience and Coping Intervention (RCI) with college students. Participants: College students (aged 18–23) from a large Midwest US university who volunteered for a randomized controlled trial during the 2015 spring semester. Methods: College students were randomly assigned to an intervention (n = 64) or a control (n = 65) group. Intervention participants received three 45-minute RCI sessions over subsequent weeks. All participants completed pre- and post-intervention assessments at the beginning of Week 1 and end of Week 3. Student resilience, coping, hope, stress, depression, and anxiety were assessed. Results. RCI participants reported significantly more hope and less stress and depression from Week 1 to Week 3 compared with control participants. Results for resilience also approached statistical significance. Effect sizes were small to moderate. Conclusions: This study found preliminary evidence that RCI is an effective resilience intervention for use with college students.  相似文献

In the hydrofracturing controversy in New York advocates hotly contested notions of the problem, what should be done, by whom, and how. This controversy can be characterized as “crowded advocacy,” involving intense mobilization and counter-mobilization of advocates with competing perspectives. Extant theories about the expansion of advocacy organizations are unclear about how advocates’ interactions shape the policy arena, particularly when there is competition within and across multiple coalitions. This article contributes by asking: How do advocates’ interactive framing dynamics shape public discourse when advocacy is crowded? It assumes that advocacy in general, and framing in particular, evolves as advocates respond to each other. I find that competing “discourse coalitions” collectively influence public discourse by articulating divergent notions of (1) what constitutes credible knowledge, (2) who can speak with authority on the issues, and (3) what institutional arrangements should be activated to manage risks. The consequence is that advocates have to react to others' framing on these issues—to defend their knowledge, their credibility, and specific institutions, rather than arguing their case on the merits. The implication is that advocacy is not only the means of influence (strategy) but also creates the context of advocacy in particular ways in a crowded field.  相似文献

This study argues that different cities in China have different resource environments available for NGOs. Organizations react to these resource environments by constructing appropriate resource strategies, which in turn shape the characteristics and structures of the NGOs of that city. It further examines how these characteristics and structures influence the construction and performance of citizenship in an authoritarian environment. Specifically, some types of NGOs encourage Chinese citizens to be passive, while others offer a model for people to actively engage with social issues. This is aptly demonstrated in an analysis of NGOs operating across four cities—Beijing, Shanghai, Kunming, and Nanjing—which reveals three different types of resource environments and behavioral models for NGOs. We subsequently discuss the implications of each model for citizen engagement.  相似文献

With survey data from 243 Latina/o early adolescent language brokers, latent profile analyses were conducted to identify different types (i.e., profiles) of brokers. Profiles were based on how often Latina/o early adolescents brokered for family members, as well as their levels of family‐based acculturation stress, negative brokering beliefs, parentification, and positive brokering beliefs. Three brokering profiles emerged: (1) infrequent‐ambivalents, (2) occasional‐moderates, and (3) parentified‐endorsers. Profile membership was significantly predicted by ethnic identification and brokering in a medical context. Respect, brokering at school, and brokering at home did not significantly predict profile membership. In addition, parentified‐endorsers had more frequent perceived ethnic/racial discrimination and depressive symptoms than other profiles. In contrast, infrequent‐ambivalents engaged in risky behaviors less frequently than other profiles.  相似文献

The role of urban expansion on bee diversity is poorly understood, but it may play an important role in restructuring pollinator diversity observed in rural regions at the urban perimeter. We studied bee communities in two habitats essential for pollinators (residential gardens and semi-natural areas) at 42 sites situated at the edge of greater Montreal, Canada. Bee species richness, abundance and functional diversity all increased with urbanization in both habitat types, but gardens and semi-natural areas supported distinct bee communities with unique responses to urbanization in terms of species turnover. Compared to semi-natural sites, residential gardens supported bees that foraged from a greater number but a lower proportion of available plant species. Bees did not discriminate between exotic and indigenous plant species in either gardens or semi-natural sites and were attracted to flowers in either habitat irrespective of their origins. Protecting semi-natural ruderal areas and providing residential garden habitats for pollinators are both effective means of promoting regional bee diversity in urbanizing regions.  相似文献

Tilt in poker implies a deviation from an individual’s usual playing style, at a strategic, emotional and behavioural level. It is a specific characteristic of poker, which can affect all kinds of players with varying degrees of frequency. In addition, tilt could be a transitional form of pathological gambling behaviour and a gateway to addiction. The main objective of this research is therefore the design and validation of a measuring scale for tilt episode frequency in an online poker gamblers’ group. Twenty-one items based on the literature and interviews with 10 poker players were created. An online self-administered questionnaire was completed by 263 poker players to validate this scale. The mean age of the sample was 26.7 (SD = 4.45). The Online Poker Tilt Scale (OPTS) consists of 17 items and is the first validated tool for measuring the frequency of tilt episodes associated with online poker. It is composed of two factors: ‘emotional and behavioural tilt’ and ‘cognitive tilt’. Tilt seems to be an essential part of understanding online poker behaviour. This tool will enable researchers studying online poker addiction to perform research on the mechanisms and processes that lead to tilt and its consequences.  相似文献

Previous research has demonstrated that social interactions underlie the development of object‐directed imitation. For example, infants differentially learn object action sequences from a live social partner compared to a social partner over a video monitor; however, what is not well understood is what aspects of social interactions influence social learning. Previous studies have found variable influences of different types of caregiver responsiveness on attention, language, and cognitive development. Therefore, the purpose of this study was to examine how the responsive style of a social partner influenced the learning of object‐directed action sequences. Infants interacted with either a sensitive or redirective experimenter before the learning trial. Results revealed infants changed their patterns of engagement; infants interacting with a sensitive experimenter had longer periods of attentional engagement than infants interacting with a redirective experimenter. Furthermore, during the learning trial, the amount of sensitivity during interaction with the social partner predicted learning scores. These findings suggest that infants' attention is influenced by social partners' interactive style during ongoing interaction, which subsequently affects how infants learn from these social partners.  相似文献

We interviewed 18 family caregivers about their communication experiences in the ICUs at an urban hospital. Analysis of their narratives suggests health literacy is important in family caregiver/healthcare provider communication, especially as complicated illnesses move the caregiver deeper into decision making. Using the domains of Yuen et al.’s conceptual model of caregiver health literacy (2015), we identified three themes within the context of ICU communication: agency, coordinated communication, and caregiver’s evolving role. We saw family caregivers negotiating domains of health literacy as they built upon knowledge of the patient’s needs, their rights as family caregivers, and the hierarchy of the professional staff. We found that these narratives represent co-created, or relational communication, rather than individual health literacy skills. Conceptualized in the transaction of relationship, health literacy is enacted; it is socially constructed and is the scaffolding upon which family caregivers make decisions, care for their loved one, and care for themselves.  相似文献
