Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation. 相似文献

Foster care provides round-the-clock substitute care for nearly 700,000 U.S. children who are temporarily or permanently separated from their family of origin each year. Each state manages its own foster care system according to federal regulations. Despite numerous large-scale federal policy reforms over the past several decades, substantial concerns remain about the experiences and outcomes of children in the foster care system. The most recent effort to reform foster care, the Family First Prevention Services Act of 2018, attempts to both reduce the use of foster care and increase the quality of care. In this report, we review how policy has shaped the experiences and outcomes of children in foster care, where policy has succeeded, and where it falls short of achieving its goals. We then identify opportunities for federal and state policy to better support the safety, health, and well-being of children in foster care. 相似文献

AbstractObjective: Examine receptivity and motivation to use/quit tobacco among college students after viewing Truth ads. Participants: Random sample of 10,000 college students invited to complete online survey February 2016 (8.5% response rate). Methods: Quasi-experimental. Participants (N?=?854) watched four ads and answered survey items for each ad. Results: Students rated ad receptivity and decreased motivation to use tobacco higher for the Catmageddon ad than the others. Regardless of ad, men and current cigarette smokers reported lower receptivity. Younger age was associated with lower motivation to use tobacco for all ads. Tobacco users reported greater motivation to quit with the Catmageddon ad. Conclusions: College students were receptive to the Truth ads, and many indicated lower motivation to use tobacco. Men, older college students, and current cigarette smokers were less receptive to the ads, reinforcing the need to develop tailored campaigns to reach these subgroups. 相似文献

This paper presents a theoretical and methodological approach to analysing images in public space as part of a transformative visual dialogue in everyday life. Images are conceptualised through the lens of sociocultural psychology and analytically approached through the metaphor of ‘the social life of images,’ by which the life cycle of images is followed as they respond and borrow from one another in a continuous dialogue. The analytical framework starts by situating the image and identifying its spatial and temporal contexts. Then, it considers the social actors influencing the image’s social life and the different stages in an image’s trajectory. Leading to an analysis of the political dynamics of an image and its potential symbolic power to influence the public discourse. Examples from street art, online, and news images will be used to illustrate the analytical approach. 相似文献

Menstruation has been historically known as a function of the female body that affects women. Trans and non-binary people face this biological function as a potential social signal of gender/sex identity. This research involves virtual ethnographic content analysis of menstruation discourse written by or informed by trans and non-binary people in addition to 19 interviews with trans and non-binary participants. The research yields analysis within three gendered/sexed social spheres that trans and non-binary bodies contest: (1) the gendering of menstrual products; (2) men’s restrooms; and (3) health care. The findings depict the variety of strategies trans and non-binary people employ when navigating and interpreting menstruation in relationship to their gender/sex identities. 相似文献

Multi-level marketing (MLM) firms recruit individuals into a business opportunity but are not required to disclose the earnings of past participants. Some MLMs voluntarily create income disclosures, which may serve both marketing and risk-management functions. We create an economic experiment to explore the impact of MLM income disclosure on consumer interest and expectations. Results suggest that disclosure does not significantly alter interest in the business opportunity but does reduce expectations, on average, when subjects are asked to estimate annual income in a lab environment. We discuss findings in the context of current regulatory policy. (JEL D18, D82, M38) 相似文献

ABSTRACTRestorative justice is regarded in modern criminal justice systems as one approach to address inadequacies in the conventional justice model. New Zealand has become a leader in implementing legislatively mandated restorative procedures. This reputation is due in part to a handful of supportive statutes: the Sentencing Act 2002, the Victims’ Rights Act 2002, the Parole Act 2002, the Corrections Act 2004 and subsequent amendments to those acts. In this article, I evaluate the practices bolstered by these acts and how effectively they operate, accounting for how legislative design may contribute to achievements and shortcomings in New Zealand's restorative justice programmes. I supplement the results by comparing New Zealand's efforts to those in Vermont, a U.S. state similarly well-regarded for its restorative policies. The evaluation of each jurisdiction's restorative justice programme is based on metrics for restorative success from Bazemore and Schiff (2005. Juvenile justice reform and restorative justice: building theory and policy from practice. Cullompton: Willan Publishing). I employ qualitative and quantitative data, surveying existing evaluations of restorative justice in New Zealand and Vermont, collecting longitudinal statistics, and conducting interviews with restorative justice practitioners. Overall, this analysis reveals that the design of restorative justice programmes requires negotiation; it is difficult to balance the dimensions of effective restorative justice with the needs of modern justice systems. 相似文献
