Background:The School Wellness Integration Targeting Child Health(SWITCH)intervention has demonstrated feasibility as an implementation approach to help schools facilitate changes in students’physical activity(PA),sedentary screen time(SST),and dietary intake(DI).This study evaluated the comparative effectiveness of enhanced(individualized)implementation and standard(group-based)***:Twenty-two Iowa elementary schools participated,with each receiving standardized training(wellness conference and webinars).Schools were matched within region and randomized to receive either individualized or group implementation *** PA,SST,and DI outcomes of 1097 students were assessed at pre-and post-intervention periods using the Youth Activity *** mixed models evaluated differential change in outcomes by condition,for comparative effectiveness,and by ***:Both implementation conditions led to significant improvements in PA and SST over time(pmprove commensurately(p value range:0.02‒0.05).There were no differential changes between the group and individualized conditions for PA(p=0.51),SST(p=0.19),or DI(p=0.73).There were no differential effects by gender(i.e.,non-significant condition-by-gender interactions)for PA(p_(for interaction)=0.86),SST(p_(for interaction)=0.46),or DI(p_(for interaction)=0.15).Effect sizes for both conditions equated to approximately 6 min more PA per day and approximately 3 min less sedentary ***:The observed lack of difference in outcomes suggests that group implementation of SWITCH is equally effective as individualized implementation for building capacity in school wellness ***,the lack of interaction by gender suggests that SWITCH can be beneficial for both boys and *** research is needed to understand the school-level factors that influence implementation(and outcomes)of SWITCH.

IT-Software SmEs in China, Technology Transfer from Universities and Entrepreneurship, a Successful Nexus？

引用

Frontiers of Business Research in China 2014年第1期8卷 18-48页

Drawing on the empirical work of a broader study, this paper examines whether technology is being successfully transferred from universities to the IT-sottware SmEs present in China, and the effectiveness of entrepreneurship in effecting such transfers. A conceptual framework was generated to guide the investigation. Data were elicited using a detailed questionnaire which generated 53 usable responses; follow-up interviews with 17 of the 53 respondents; and four interviews with relevant government officials （civil servants from the ministry of Science and Technology and state-owned banks）. There were three main fmdings. Chinese software SmEs tend to be reluctant to adopt new technologies from local tmiversities; there is a lack of common purpose between the parties; and entrepreneurs who did undertake such technology transfer felt the process was badly impeded by the lack of available finance, and expressed fears about poor protection of intellectual property rights in China. The majority of the sample firms acted opportunistically, taking advantage of the benefits offered under government schemes to earn rapid returns mainly using extant technologies. These conclusions suggest that the Chinese government＇s policies in this area of technology transfer have had only limited success.
