The efficacy of a Web‐based personalized feedback program—electronic CHECKUP TO GO (e‐CHUG), aimed at reducing heavy drinking in 1st‐year university students—is evaluated. Results indicated that high‐risk students in the e‐CHUG group reported significantly greater reductions in weekly drinking quantity frequency of drinking to intoxication, and occurrence of alcohol‐related problems. Recommendations for integrating Web‐based alcohol programs into a comprehensive prevention program are discussed. 相似文献

The Danish e-commerce strategy is a highly ambitious effort to become the world's leading IT nation. Instead of a production-led approach aimed at stimulating domestic hardware and software production, Denmark has pursued a demand-oriented approach focused on promoting the widespread adoption of e-commerce in the Danish society. The Danish government has developed a number of e-commerce initiatives via public-private sector partnerships--an approach we refer to as "governance." So far, it appears that Denmark has been successful in promoting business-to-business (B2B) e-commerce, with a number of Danish companies being global leaders in the use of B2B applications. On the other hand, Denmark has had less success in achieving widespread use of business-to-consumer (B2C) e-commerce. This article analyzes the Danish national environment for e-commerce, discusses four sets of governance initiatives aimed at the development of e-commerce, and analyzes the reasons for its success in B2B and relative failure in B2C adoption. 相似文献

Component content management (CCM) enables organizations to create, manage, and deliver content as small components rather than entire documents. As CCM methodologies, processes, and technologies are increasingly adopted, CCM is reshaping technical communication (TC), the roles of technical communicators, and the skills they need for career success. This article reviews scholarly and trade publications that describe changes in roles and needed skills in CCM environments and identifies implications of these changes for TC education. 相似文献

This study examined anterior chain whole body linkage exercises, namely the body saw, hanging leg raise and walkout from a push-up. Investigation of these exercises focused on which particular muscles were challenged and the magnitude of the resulting spine load. Fourteen males performed the exercises while muscle activity, external force and 3D body segment motion were recorded. A sophisticated and anatomically detailed 3D model used muscle activity and body segment kinematics to estimate muscle force, and thus sensitivity to each individual's choice of motor control for each task. Gradations of muscle activity and spine load characteristics were observed across tasks. On average, the hanging straight leg raise created approximately 3000 N of spine compression while the body saw created less than 2500 N. The hanging straight leg raise created the highest challenge to the abdominal wall (>130% MVC in rectus abdominis, 88% MVC in external oblique). The body saw resulted in almost 140% MVC activation of the serratus anterior. All other exercises produced substantial abdominal challenge, although the body saw did so in the most spine conserving way. These findings, along with consideration of an individual's injury history, training goals and current fitness level, should assist in exercise choice and programme design. 相似文献

ABSTRACT Experiential learning (EL) has great potential to prepare students to work on interdisciplinary and global challenges across traditional boundaries, as well as support them in the development of reflective skills. In this study, we explore reflection as a central element for EL in the university wide interdisciplinary course Experts in Teamwork (EiT). Based upon 17 years of experience with the development of EiT, perspectives from the literature, and critically analyzing current practices, we describe two key findings from this ongoing exploration: the need to develop a framework for such a course and the need for training of teaching staff. 相似文献

Gender stereotypes in the natural sciences may discourage girls from pursuing STEM fields, thus contributing to the differential STEM pathways of males and females. This paper exploits quasi-experimental data from a vignette study to investigate teachers’ gender bias in STEM at the transition to upper secondary school in Denmark—a key stage in students’ educational trajectories. I investigate if teachers have a higher probability of recommending a STEM track to a (vignette) male student compared with a (vignette) female student and if teachers’ STEM recommendations interact with their demographic characteristics. Results show that, while there is a gender gap of 10 percentage points in the likelihood of being recommended a STEM track, the difference is not statistically significant. Furthermore, teachers’ gender bias is influenced by the teacher's own gender and cultural capital. Consequently, the paper shows that teachers’ gender bias varies with teachers’ demographic characteristics and teachers with high levels of cultural capital can push back against gender stereotypes in STEM. 相似文献

In search of a useful theory of the productive potential of intellectual property rights 总被引:1,自引:0,他引:1
Mainstream theory, which has informed the belief systems regarding the operation as well as the predicted social and economic effects of IPR systems, cannot explain why the IPR system generates different performance results and varying potential for growth across the firms, sectors and nations participating in the IPR system. This paper sketches a theory of the ‘productive potential of intellectual property rights’ which is able to do just that. Focusing on the ‘rules of the game’ embedded in the institutional IPR environment and the ‘play of the game’ within the alternative institutions of IPR governance, the paper emphasizes the importance of the nature or quality of the relationships among IPR stakeholders and the contribution of such relationships to the processes of financial and non-financial value creation and distribution from IPRs. The central role of cooperation, asymmetric relationships, and the effective resolution of conflicting interests amongst stakeholders is addressed. It is suggested that the proposed framework provides a better starting point for the design of IPR policy and management. 相似文献

ABSTRACT
Acute and adaptive changes in systemic markers of oxidatively generated nucleic acid modifications (i.e., 8-oxo-7,8-dihydro-2?-deoxyguanosine (8-oxodG) and 8-oxo-7,8-dihydroguanosine (8-oxoGuo)) as well as inflammatory cytokines (i.e., C-reactive protein, interleukin-6, interleukin-10, and tumour necrosis factor alpha), a liver hormone (i.e., fibroblast growth factor 21 (FGF21)), and bone metabolism markers (sclerostin, osteocalcin, C-terminal telopeptide, and N-terminal propeptide of type 1 procollagen) were investigated following a marathon in 20 study participants. Immediate changes were observed in inflammatory cytokines, FGF21, and bone metabolism markers following the marathon. In contrast, no immediate changes in urinary excretion of 8-oxodG and 8-oxoGuo were evident. Four days after the marathon, decreased urinary excretion of 8-oxodG (-2.9 (95% CI -4.8;-1.1) nmol/24 h, P < 0.01) and 8-oxoGuo (-5.8 (95% CI -10.3;-1.3) nmol/24 h, P = 0.02) was observed. The excretion rate of 8-oxodG remained decreased 7 days after the marathon compared to baseline (-2.3 (95%CI -4.3;-0.4) nmol/24 h, P = 0.02), whereas the excretion rate of 8-oxoGuo was normalized. In conclusion marathon participation immediately induced a considerable inflammatory response, but did not increase excretion rates of oxidatively generated nucleic acid modifications. In fact, a delayed decrease in oxidatively generated nucleic acid modifications was observed suggesting adaptive antioxidative effects following exercise. 相似文献
