The main aim of this article is to study the social processes occurring during the implementation of radical organizational innovation. Our aim is to understand the nature of the development of radical innovation by identifying the social processes, that are taking place. The perspective for the analysis stems from “grounded theory” as a generative and inductive analytical strategy (Glaser & Strauss, 1967). An in-depth case study was thoroughly analysed. A total of 14 indepth interviews were conducted with key informants selected according to “theoretical sampling” criteria. The systematic use of the “constant comparative method” allowed us to differentiate grounded theories leading to a “conceptual saturation” of the categories generated from the empirical data. Results show the emergence of two basic processes, “learning” and “adaptation”, during the development of radical innovation. A “grounded” theory concerning the development of radical innovation is proposed, emphasizing the organization's selfregulating capacity for learning and adapting. Our results describe innovation as an adaptable response that causes disorder in terms of “a creative tension in the system”. Finally, the methodological implications of grounded theory are discussed with regard to the study of radical innovation. The requisites and limitations observed in using grounded theory are outlined.  相似文献

Caregiver social support has been shown to be protective for caregiver mental health, parenting and child psychosocial outcomes. This is the first known analysis to quantitatively investigate the relationship between caregiver social support and adolescent psychosocial outcomes in HIV‐endemic, resource–scarce Southern African communities. A cross‐sectional household survey was conducted over 2009–2010 with 2,477 South African adolescents aged 10–17 and their adult caregivers (18 years or older) in one urban and one rural community in South Africa’s KwaZulu‐Natal province. Adolescent adjustment was assessed using adult caregiver reports of the Strengths and Difficulties questionnaire (SDQ), which measures peer problems, hyperactivity, conduct problems, emotional symptoms and child prosocial behavior. Hierarchical linear regressions and multiple mediation analyses, using bootstrapping procedures, were conducted to assess for: (a) direct effects of more caregiver social support on better adolescent psychosocial wellbeing; and (b) indirect effects mediated by better parenting and caregiver mental health. Direct associations (p < .001), and indirect associations mediated through better parenting, were found for all adolescent outcomes. Findings reinforce the importance of social support components within parenting interventions but also point to scope for positive intervention on adolescent psychosocial wellbeing through the broader family social network.  相似文献

This study examines the relationship between efficacy beliefs and task engagement in and over time, at both the individual and collective levels. We conducted latent growth curve analyses using data from 372 university students (individual level) who were assigned to one of 79 e‐work groups (collective level). The participants carried out three collaborative tasks in a laboratory setting. Results reveal, at both levels, that the level of task engagement of participants and groups with high initial levels of efficacy beliefs remained stable, whereas the level of task engagement of participants and groups with low initial levels of efficacy beliefs decreased significantly over time. Moreover, the relationships linking the parallel constructs were functionally equivalent across levels. Theoretical and practical implications are discussed from the perspective of Bandura's social cognitive theory.  相似文献

Recall and recognition of various aspects of three places were studied under incidental and intentional conditions. Data showed that subjects passing through a place incidentally remembered structural features such as walls better than variable features such as furniture. On the other hand, subjects passing through a place knowing they will be tested for memory of its remembered the variable elements better than the structural elements. The results are interpreted in terms of intentionally governed coding.  相似文献

There has been no systematic, large-scale statistical investigation of the link between gambling and suicide, despite the suggestion of such a link from small-scale case studies. This article examines whether gamblers or those associated with them are prone to suicide and whether gaming communities experience atypically high suicide rates. Las Vegas, the premier U.S. gambling setting, displays the highest levels of suicide in the nation, both for residents of Las Vegas and for visitors to that setting. In general, visitors to and residents of major gaming communities experience significantly elevated suicide levels. In Atlantic City, abnormally high suicide levels for visitors and residents appeared only after gambling casinos were opened. The findings do not seem to result merely because gaming settings attract suicidal individuals.  相似文献
