The North American Carbon Program (NACP) was formed to further the scientific understanding of sources, sinks, and stocks of carbon in Earth's environment. Carbon cycle science integrates multidisciplinary research, providing decision-support information for managing climate and carbon-related change across multiple sectors of society. This investigation uses the conceptual framework of communities of practice (CoP) to explore the role that the NACP has played in connecting researchers into a carbon cycle knowledge network, and in enabling them to conduct physical science that includes ideas from social science. A CoP describes the communities formed when people consistently engage in shared communication and activities toward a common passion or learning goal. We apply the CoP model by using keyword analysis of abstracts from scientific publications to analyze the research outputs of the NACP in terms of its knowledge domain. We also construct a co-authorship network from the publications of core NACP members, describe the structure and social pathways within the community. Results of the content analysis indicate that the NACP community of practice has substantially expanded its research on human and social impacts on the carbon cycle, contributing to a better understanding of how human and physical processes interact with one another. Results of the co-authorship social network analysis demonstrate that the NACP has formed a tightly connected community with many social pathways through which knowledge may flow, and that it has also expanded its network of institutions involved in carbon cycle research over the past seven years.  相似文献

ABSTRACT

African American adolescents continue to be disproportionately impacted by HIV, sexually transmitted infections (STIs), and unanticipated pregnancies. In-depth, face-to-face interviews among a convenience sample of 32 African American adolescents (16 male and 16 female) were used to explore the reasons why some adolescents decided to engage in sex while others chose to delay sexual debut. Data were analyzed using a thematic analysis. Among the overall sample, psychological motivations, external pressure, physical pleasure seeking, and relationship-related motivations were the major themes cited for engaging in sex by participants and their friends. External support, motivation to avoid negative consequences, not feeling ready or lacking interest in sex, and having negative views about sex were among the major reasons for delaying sex. Several of the emergent themes showed gender differences. Suggestions for future research include the need for sexual education, and STI/HIV prevention programs that are gender sensitive and flexible enough to accommodate multiple factors related to sexual debut.  相似文献

A study of 133 full time employees with parent care responsibilities investigated various factors that could reduce this group's future caregiving commitment to aging parents. Study factors included: caregiver attributes, level of caregiving involvement, job stress, tensions between the caregiver and the dependent parent, caregiver's level of physical and mental strain, and limited support from family and friends. The relationship between the caregiver and the parent was the best predictor of sustained commitment to caregiving. One aspect of the employees' work experience made a small, but important contribution to respondents' future care plans. Those employees who frequently adjusted their work schedule and routine to accommodate parent care demands were less likely to sustain their caregiving commitment. Reasons for these findings are explored and implications for social policy and clinical practice are discussed.  相似文献

Based on a social intervention research study into mentoring with women from socioeconomically disadvantaged communities, this study considers some of the key differences between traditional workplace and community-based mentoring when used as a social work intervention. The study involved 18 women who participated in a preparation-for-mentoring groupwork program for 12 months. Eleven of these participants were then matched with a mentor and supported in this relationship for a further 12 months. Qualitative analysis points to three key factors likely to enhance the success of community-based mentoring relationships: (i) relational qualities, such as trust, engagement, and authenticity; (ii) mentees' readiness for change and ability to overcome adversity; and (iii) mentors' practical assistance with tasks and overcoming obstacles. Social workers implementing a community-based mentoring program need to be mindful of the importance of these factors in order to ensure that mentees are supported to engage effectively in any mentoring relationship and overcome structural, community, and familial barriers that may adversely affect them.  相似文献

Unemployment among persons with disabilities is high. The situation is worse for women with disabilities as they experience multiple disadvantages on account of gender and disability. The condition for women with disabilities in Ghana could be more complicated, given the intersection of disability, gender, poverty, cultural beliefs and practices. As employment provides not only income for women with disabilities but opportunities for social participation and increases psychological well-being as well as self-esteem, it is imperative to remove barriers that hinder their employment. The current study examines issues associted with the unemployment of women with physical disabilities in Tamale, Ghana, and makes recommendations to policy-makers and practitioners in order to improve the condition of persons with disabilities in general, and particularly women with disabilities.  相似文献

Postpartum Depression (PPD) affects approximately 9 - 20% of women. Many women with PPD go undiagnosed and/ or do not follow through on referrals for treatment. Although the most routinely prescribed treatments for PPD are antidepressant medication and psychotherapy, a significant number of women desire non-traditional options. This article provides a systematic review of ten recently published, randomized clinical trials in the examination of the effectiveness of complementary health approaches—the use of non-mainstream products and interventions—on PPD. A search of nine databases of the English language literature from the years 2006 to 2018 was performed. Review criteria included published work, utilization of randomized-controlled trials, and the use of a reliable and valid measurement tool to identify cases of PPD and monitor changes in symptom severity. The studies reviewed focused on the following interventions: aromatherapy, bright light therapy, electroacupuncture, infant massage, iron supplementation, mindfulness training, omega-3 fatty acids, saffron, and yoga. Outcomes demonstrate the feasibility and safety of these approaches, as well as varying degrees of effectiveness. While many were pilot studies using small sample sizes, the results are encouraging and substantiate the need for additional trials. Studies are summarized and limitations and implications for social work and future research are described.  相似文献

There is limited knowledge on re-entry initiatives for formerly incarcerated women specifically on building women's advocacy and leadership skills. Our research highlights an empowerment evaluation on ReConnect, a 12-session; innovative advocacy and leadership development program rooted in an integrated framework of empowerment, and transformational leadership theories. Using thematic analysis, we coded three focus groups with 24 graduates, for themes that matched our framework's concepts. ReConnect graduates reported being empowered by the information they received on parental rights, housing, and employment. Participants agreed that ReConnect improved their communication skills, preparing them to advocate for themselves and community members.  相似文献
