This pilot study compared the use of an enriched multimedia eBook with traditional methods for teaching the gross anatomy of the heart and great vessels. Seventy‐one first‐year students from an Australian medical school participated in the study. Students' abilities were examined by pretest, intervention, and post‐test measurements. Perceptions and attitudes toward eBook technology were examined by survey questions. Results indicated a strongly positive user experience coupled with increased marks; however, there were no statistically significant results for the eBook method of delivery alone outperforming the traditional anatomy practical session. Results did show a statistically significant difference in the final marks achieved based on the sequencing of the learning modalities. With initial interaction with the multimedia content followed by active experimentation in the anatomy lab, students' performance was improved in the final test. Obtained data support the role of eBook technology in modern anatomy curriculum being a useful adjunct to traditional methods. Further study is needed to investigate the importance of sequencing of teaching interventions. Anat Sci Educ. 7: 19–27. © 2013 American Association of Anatomists. 相似文献

The governance of sustainable socio-technical transitions 总被引：8，自引：2，他引：8
A quasi-evolutionary model of socio-technical transitions is described in which regimes face selection pressures continuously. Differentiated transition contexts determine the form and direction of regime change in response to these pressures. The articulation of pressures, and the degree to which responses are coordinated and based on resources available within the regime, define the transition context. Four alternative contexts are described: endogenous renewal; re-orientation of trajectories; emergent transformation and purposive transitions. Agency and power in the governance of regime transformation are analysed. Power to affect change depends on regime membership, the distribution of resources for change and expectations. 相似文献

As the nation's principal environmental agency, the EPA is responsible for conveying a wide array of information to the American public. The agency utilizes glossaries, lexicons, dictionaries, and thesauri to define environmental terms, regulations, scientific concepts, and issues. However, the approach taken to defining environmental terms is challenging and there is often more than one definition for the same term. This article examines how the EPA defines environmental terms and how it can be difficult to choose the most appropriate definition or environmental term. 相似文献

In order to determine the influence of two artificially induced alkalotic states on the ability to perform maximal exercise, six male subjects (mean age, 22.0 years; mean height, 176.8 cm; mean weight, 69.1 kg; mean VO2 max, 3.83 l min-1) were studied during three experimental trials. The subjects performed six 60-s cycling bouts, at a work rate corresponding to 125% VO2 max, with 60 s recovery between work bouts; these regimens were performed 1 h after the ingestion of a solution containing either; I, placebo; II, NaHCO3 in a dosage of 0.15 g per kg body weight; or III, NaHCO3 0.30 g per kg body weight. The sixth work bout was continued until the pedal velocity dropped below 50 rev min-1. Total work done for the entire work period was calculated. Blood samples were taken from a forearm vein prior to the exercise bouts for analysis of pH and HCO3. The results showed a significant pre-exercise difference in pH and HCO3 for all conditions (P less than 0.01). In conditions where artificial alkalosis had been achieved prior to exercise there was significant increase in the work produced: I, 121.6 kJ; II, 133.1 kJ; III, 133.5 kJ (P less than 0.05). The time to fatigue in the six bout was also significantly increased; I, 74.7 s; II, 111.0 s; III, 106.0 p (P less than 0.05). There were no significant differences between conditions II and III. Thus augmentation of the bicarbonate reserves has a significant positive effect on the energy metabolism in interval-type exercise, leading to an increase in the work done and in the time to fatigue.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Verbal reinforcement and contingency management Was used to increase the response rate correct in a class group of twenty‐nine boys in year 7 of schooling. The response rate increased by six times over a period of thirty school days, on data using daily measurements. On the Gap achievement test, the mean reading age prior to the study was 8.0 years. After the thirty day period of instruction it was 10.0 years. 相似文献

That women are still stereotyped despite the continuing activism of the women's liberation movement is clearly demonstrated in the following study of a sample of early 1971 network TV ads. Focusing on the advertising viewed in millions of homes during prime‐time, the authors conclude that women are most often seen as decorative (sex objects) or useful (housewives and mothers), but hardly ever as professionals or working wives. Dr. Dominick is an assistant professor in the Department of Communication Arts and Sciences of Queens University while Miss Rauch is a recent graduate of that department. 相似文献

Technology assessment (TA) has a strong history of helping to identify priorities and improve environmental sustainability, cost-effectiveness and wider benefits in the technology policies and innovation strategies of nation-states. At international levels, TA has the potential to enhance the roles of science, technology and innovation towards achieving the Millennium Development Goals, effectively implementing the UN Framework on Climate Change and fostering general global transitions to ‘green economies’. However, when effectively recommending single ostensibly ‘best’ technologies or strategies, TA practices can serve unjustifiably to ‘close down’ debate, failing adequately to address technical uncertainties and social ambiguities, reducing scope for democratic accountability and co-ordination across scales and contexts. This paper investigates ways in which contrasting processes ‘broadening out’ and ‘opening up’ TA can enhance both rigour and democratic accountability in technology policy, as well as facilitating social relevance and international cooperation. These methods allow TA to illuminate options, uncertainties and ambiguities and so inform wider political debates about how the contending questions, values and knowledges of different social interests often favour contrasting innovation pathways. In this way TA can foster both technical robustness and social legitimacy in subsequent policy-making. Drawing on three empirical case studies (at local, national and international levels), the paper discusses detailed cases and methods, where recent TA exercises have contributed to this ‘broadening out’ and ‘opening up’. It ends by exploring wider implications and challenges for national and international technology assessment processes that focus on global sustainable development challenges. 相似文献
