The cross-sectional study aimed to investigate the career adaptability and its associated factors among 431 student nurses. Participants completed questionnaires on demographics, career adaptability, adversity quotient, clinical learning environment and social support. Findings revealed that student nurses' adversity quotients, individualized clinical learning environment, and family social support associated positively with their degree of career adaptability, even after multiple adjustments. Additionally, career adaptability scores were higher among associate degree student nurses and those who had served as student leaders. These findings may provide referable evidence for schools and educators to improve student nurses' career adaptability.  相似文献

The physical environment is thought to influence walking; however, daily variations in perceived environment have received little attention. The current study sought to examine if key within-person factors (i.e., implementation intentions, social support, affect and self-efficacy) would be associated with walking and if perceived access to supportive environments (e.g., access to nice walking paths) and perceived environmental barriers (e.g., bad weather and safety issues) were uniquely associated with walking after controlling for other constructs. Participants (N?=?14, 50.0% men, 78.6% White, M age?=?59.4?±?6.4) were in the intervention arm of an 8-week controlled trial promoting walking via personal digital assistants. Participants completed electronic surveys twice a day (total entries?=?804) in which they reported brisk walking levels and psychosocial and environmental factors. Multilevel modelling was used to examine within-person variations in constructs as determinants of walking. Results suggested that daily variations in implementation intentions, social support and positive affect were positively associated with walking. Further, perceived access to supportive environments, though not perceived environmental barriers, was positively associated with walking after controlling for other constructs (p?<?0.05). Future research should explore intervention components that target context-specific information about perceived access to supportive environments as part of a broader perspective on intervention development.  相似文献

Spatial knowledge, necessary for efficient navigation, comprises route knowledge (memory of the landmarks along a route) and survey knowledge (map-like). Available data on the retention in humans of spatial knowledge show that this does not decline systematically over months or years. Here, two groups of participants elaborated route and survey knowledge during navigation in a complex virtual environment before performing route and survey tasks. Both groups were tested 5 minutes after learning and 3 months later, while one group was also tested 1 week and 1 month later (repeated testing). Performance was similar in both groups on the first testing session, remained stable in the repeated tested group, but decreased in the non-repeated tested group, especially on route tasks. These results are the first to reveal a substantial and selective decline of spatial knowledge, occurring only if there is no possibility of reactivating knowledge along repeated testing.  相似文献

This study examines employees' personal control and feelings of helplessness at work as partial mediators of the relationship between the supervisor–employee feedback environment and well-being (job satisfaction, job depression, job anxiety, turnover intentions) at work. Findings are reported from a cross-sectional field study with 345 participants from three different industries. Hierarchical regression analyses showed that feedback environment was positively related to job satisfaction, personal control over information and decisions, and was negatively related to helplessness, job depression, and turnover intentions. Furthermore, personal control partially mediated the relationships between feedback environment and job satisfaction as well as job depression. Helplessness partially mediated the relationships between feedback environment and job depression, job satisfaction, and turnover intentions. This study adds to the literature on feedback environment in highlighting the importance of the supervisor–employee feedback environment for well-being at work and introducing personal control and helplessness as mediating variables.  相似文献

The study examined the school adjustment of South African adolescents affected by HIV and AIDS . Participants were a convenient sample of 60 adolescents from a secondary school in a major South African city (females = 73 .33%, 50% affected by HIV and AIDS, grade 8 = 40%, grade 9 = 30%, grade 10 = 30%, age range = 16–18 years) . Data on their personal functioning were gathered using the Beck Youth InventoryTM and the Enhanced School Support Inventory (ESSI) . The data analysis comprised between-group and within-group comparisons, using the t-test statistic . Findings suggest that adolescents affected by HIV and AIDS had significantly lower psychological and behavioural functioning than their typical other peers . Results also show that these affected learners had lower school adjustment than their typical peers . The schools environment can support comprehensive interventions to addresses psychosocial vulnerability among adolescents affected by HIV and AIDS .  相似文献

The purpose of this study was to assess developmental and social determinants of the age at which children become aware that the social environment can be marked by categorization into religious groups and that those groups are associated with different religious beliefs. The results show that middle childhood is a critical period for this religious social categorization. Moreover, social factors play a role in the development. Religious categorization is likely to appear sooner in children attending heterogeneous schools than in those at homogeneous schools, and children from the minority religious group in the country understand religious categorization earlier than children from the majority group. However, no relation was found between the age at which religious categorization was understood and parents’ religious socialization practices. This study is of both theoretical and practical interest: It complements what is already known about gender, race, and ethnic categorization by integrating developmental and social frameworks, and it can serve as a guideline for educational programs.  相似文献

The post‐industrial world is now at a cross‐roads where the choice of evolutionary paths means the difference between ensuring the long‐term survival of human communities and preservation of biodiversity, or the eventual downgrading of life quality and biospheric complexity. An emerging path towards ecological sustainability is explored in relation to its implications for the design of post‐industrial organizations. The shift from a sociotechnical to a socio‐ecological systems paradigm is discussed, with references to the theoretical and methodological expansions required to advance this paradigm in management practice. Concepts which revision organizational‐environment relationships, and lead to social and technical innovations in the transition towards an ecologically sustainable society are also discussed.  相似文献

The purpose of this article is to develop a framework for the origin of foresight. Following a review of arguments for foresight as genetically inherited versus environmentally acquired, the understanding of foresight is expanded through a behaviorist perspective and through an evolutionary perspective. The framework established makes it possible to deploy evolutionary logic to explain foresight as well as to enhance our understanding of foresight, both on individual (e.g., managerial) and aggregated (e.g., organizational) levels.  相似文献
