Research on sense of community (SOC) has traditionally been approached from a resource perspective. Recently, however, research on the experience of SOC has evolved to include a related but distinct construct of sense of community responsibility (SOC‐R), or feelings of accountability for the well‐being of a community. This study applied item response theory to examine the psychometric properties of a SOC‐R scale used in an evaluation of community‐based substance abuse prevention coalitions. Data were collected in 2017 from coalition members (analytic sample = 309) in the northeastern United States. Findings indicate that the scale was reliable, unidimensional, and functioned well, particularly at low and moderate levels of the construct. The addition of two items intended to capture higher levels of the construct improved the scale's functioning at higher levels of SOC‐R. The adapted SOC‐R scale was also shown to have moderately strong relationships with conceptually relevant variables, including SOC, coalition participation, number of roles performed in the coalition, and engagement in community action activities. These findings provide empirical evidence to support the reliability and validity of the SOC‐R scale, and have critical implications for our conceptualization of the SOC construct, its measurement, and for the evaluation of community‐based prevention interventions.  相似文献

Recent scholarship argues that beliefs in biblical literalism might keep conservative Protestants out of STEM. Two of the groups that are most underrepresented in STEM, black Americans and Latinos, are also two of the most religious populations in the United States, and specifically overrepresented in theologically conservative Christian traditions. Yet, prior work also suggests that churches help promote positive educational outcomes. To interrogate the potential relationship between STEM educational aspirations and religious faith, we explore how black and Latino Christians perceive the potential impact of science education on religious faith. Analysis of 40 interviews reveals that both black Americans and Latinos have concerns about science teachers being biased. Yet, the groups differ in their assessment of the danger of anti-religious bias. Black Americans put confidence in the Christian community to incubate children from harm to their faith; therefore, they believe the effect of science education on religious faith is either neutral or positive. Latinos, however, raise concerns about the authority of science educators, rather than science curriculum. Overall, the results shift the conversation on conservative religion and science education from solely discussing content to exploring issues of bias and authority.  相似文献

Recent advances in virtual technologies have allowed the investigation of simulated moral actions in aversive moral dilemmas. Previous studies have employed diverse populations to explore these actions, with little research considering the significance of occupation on moral decision-making. For the first time, in this study we have investigated simulated moral actions in virtual reality made by professionally trained paramedics and fire service incident commanders who are frequently faced with and must respond to moral dilemmas. We found that specially trained individuals showed distinct empathic and related personality trait scores and that these declined with years of experience working in the profession. Supporting the theory that these professionals develop resilience in moral conflict, reduced emotional arousal was observed during virtual simulations of a distressing dilemma. Furthermore, trained professionals demonstrated less regret following the execution of a moral action in virtual reality when compared to untrained control populations. We showed that, contrary to previous research, trained individuals made the same moral judgements and moral actions as untrained individuals, though showing less arousal and regret. In the face of increasing concerns regarding empathy decline in health care professionals, we suggest that the nature of this decline is complex and likely reflects the development of a necessary emotional resilience to distressing events.  相似文献

Academic scientists in the United States are relatively nonreligious, at least compared to the general population, and some evidence suggests that the professional culture of academic science may foster perceptions of discrimination among scientists who are religious. We examine perceptions of religious discrimination among biologists and physicists in the United States. The analysis shows that Protestant, Muslim, and adherents of “other” traditions report higher rates of religious discrimination in both biology and physics relative to those who do not identify with a religion. Jewish and Catholic adherents report higher rates of discrimination in biology but not in physics. Most of the religious identity effects among biologists are not explained away by measures of beliefs, practices, or professional and demographic characteristics. On the other hand, religious identity differences in perceptions of religious discrimination among physicists are mediated by measures of religious practice. On the whole, these findings suggest that religious identity itself is more stigmatized in biology than in physics. Results have implications for how university professors—and academic scientists in particular—relate to the broader public.  相似文献

This mixed-methods study applies Communication Accommodation Theory to explore how liking, power, and sex predict one’s likelihood for using textisms in digital interpersonal interactions. Textisms are digital cues that convey nonverbal meaning and emotion in text communication. The main experiment used a hypothetical texting scenario to manipulate textism amounts (none/many) and participant’s perceived power levels (low/equal/high) during texting interactions to examine the number of textisms participants used in subsequent responses in comparison to the number of textisms they viewed. Primary results show that (1) participants moderately converged to use similar amounts of textisms, and (2) those with low power who viewed many textisms were more likely to use textisms themselves during subsequent responses. Through the examination of adaption behaviors in text messaging, scholars can better understand the contexts in which users will include textisms to intentionally convey nonverbal meaning and emotion in digital communication.  相似文献

Depression is prevalent among mothers who participate in home visitation programs. This case study describes In-Home Cognitive Behavioral Therapy (IH-CBT), an empirically based treatment for depressed mothers that is strongly integrated with ongoing home visitation. The use of a Parenting Enhancement for Maternal Depression (PEMD) module was added to address parenting difficulties in a depressed mother. This case describes issues and challenges encountered in delivering treatment in the home with low-income, depressed mothers. Issues involving engagement, adaptation to the setting, responding to the unique needs of low-income mothers, and partnership with concurrent home visiting to optimize outcomes are considered. Long-term follow-up (18 months after the end of treatment) permits examination of sustainability of gains. Implications for treating this high-risk population are discussed.  相似文献
