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 brown carpet beetle Attagenus smirnovi, Zhantiev 1973 (Coleoptera: Dermestidae) is an important pest of objects of organic origin in museums of cultural and natural history in Europe. Future climate changes are expected to lead to increasing temperatures, which will affect the pest status of this species. In the present study a laboratory investigation was conducted to elucidate the effect of temperature and humidity on the amounts of organic material consumed by larvae of A. smirnovi. In the case of new and old skin, consumption was approximately twice as high at 28 °C compared to 20 °C. Wool was consumed in the greatest amounts: 169 mg of wool was consumed in three months by 30 A. smirnovi larvae. The expected future climate changes in Scandinavia are assumed to lead to higher temperatures in museums and stores where climate is not regulated. Updated data on the present distribution of A. smirnovi in Europe show that it is widespread and common, also in regions with a climate that does not support its survival out of doors. Thus, dispersal of this pest probably only rarely occurs by flight, but usually with human activity. Due to the widespread distribution of A. smirnovi, it is likely that damages in museums and collections in Scandinavia due to this pest will increase as climate changes come into effect.  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

One of the aims of participatory action research (PAR) is to bring realities of lives closer together through dialogue and ‘conscientization’, raising critical awareness among participants from all backgrounds. Promoting participation often assumes a power shift from the decision-makers to the majority of society, who can be the end-receivers of decisions made. Once some kind of awareness is achieved, the participants should be able to challenge the causes of their perceived oppression, or resolve the suffering that is endured, if that is what they hope to achieve. However, the situation is more complex in many contemporary societies, in which there are not only differing cultural beliefs related to religion, but different ontologies about being and living in the world. There is much contemporary debate about the possibilities of critique that take on board divergent sociomaterial realities within the same classroom. Practical and structural differences can pose challenges to conducting PAR research. In this article, we address the distinctive nature of PAR in relation to a culturally diverse group of participants. We argue that research using a PAR framework can result in subtle ethical challenges, which also provide insights for opportunities and strategies. Drawing from the authors’ experiences in multicultural education and working with culturally diverse youth and postgraduate students, opportunities and challenges of applying a PAR approach are discussed. We conclude with the suggestion that PAR remains consistent with its original transformative goals, but also remain open to further explorations of activism that address pressing contemporary concerns within culturally complex societies.  相似文献

The topic in this paper is how former special needs students with academic competence from upper secondary school succeed in education on a higher level. The study concentrates on students who at their start in upper secondary education were registered with problems of concentration, difficulties in reading, writing or mathematics. The main part of this paper will base on qualitative interviews with nine former special needs students. Seven out of the nine informants were registered with reading and writing difficulties. However, it is also possible to compare these informants with longitudinal data from a larger group of students who have been followed prospectively since spring 1996. Theoretically the study is based on life course research with special emphasis on social transitions. In transitional processes between different educational arenas gatekeepers'often play important roles. This study will examine how such gatekeepers, e.g. teachers, may facilitate or obstruct these transitions for a vulnerable group like former special needs students.  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

Structured talent identification and development, it has been argued, is one of the foundations of international sporting success and many modern elite sport systems have applied normative talent development (TD) models. The success of Norwegian handball, however, is based on an alternative approach to TD. Norwegian handball is characterized by a heterarchical organizational structure in which several key actors function highly autonomously. The aim of this article is three-fold: (a) to describe the organization of TD in Norwegian handball, (b) to identify how the inherent organizational characteristics of Norwegian handball have influenced the TD processes used and (c) to discuss if contemporary TD models provide an adequate conceptualization of the model used in Norwegian handball. This case study includes three units of analysis: (i) the overall organizational structure of Norwegian handball, (ii) the characteristics of the key actors involved and (iii) the inter-communication and collaborations of the key actors. The data sources were (a) documents and (b) interviews with 11 key informants. The informants were selected strategically to represent experienced coaches and professionals from multiple organizational units. The National Handball Federation uses a broad-based model for TD: 23% of male handball players and 15% of female handball players from the age of 13–17 years participate in regional-level initiatives in addition to practising daily in community-based volunteer sport clubs and sport schools. Findings reveal that the broad base of TD initiatives creates multiple access points to the talent pipeline for adolescents. However, because the heterarchical structure involves many actors, the unintended consequences are often related to (im)properly managing training and competition loads. There is a need therefore for well-developed coordination mechanisms and good communication between the key actors involved.  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, < 0.01) and 8-oxoGuo (-5.8 (95% CI -10.3;-1.3) nmol/24 h, = 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, = 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

ABSTRACT

There are quite a few challenges in the development of an automated writing placement model for non-native English learners, among them the fact that exams that encompass the full range of language proficiency exhibited at different stages of learning are hard to design. However, acquisition of appropriate training data that are relevant to the task at hand is essential in the development of the model. Using the Cambridge Learner Corpus writing scores, which have been subsequently benchmarked to Common European Framework of Reference for Languages (CEFR) levels, we conceptualize the task as a supervised machine learning problem, and primarily focus on developing a generic writing model. Such an approach facilitates the modeling of truly consistent, internal marking criteria regardless of the prompt delivered, which has the additional advantage of requiring smaller dataset sizes and not necessarily requiring re-training or tuning for new tasks. The system is developed to predict someone’s proficiency level on the CEFR scale, which allows learners to point to a specific standard of achievement. We furthermore integrate our model into Cambridge English Write & ImproveTM—a freely available, cloud-based tool that automatically provides diagnostic feedback to non-native English language learners at different levels of granularity—and examine its use.  相似文献
