Virtual worlds and moral evaluation     

Jeff Dunn 《Ethics and Information Technology》2012,14(4):255-265

Consider the multi-user virtual worlds of online games such as EVE and World of Warcraft, or the multi-user virtual world of Second Life. Suppose a player performs an action in one of these worlds, via his or her virtual character, which would be wrong, if the virtual world were real. What is the moral status of this virtual action? In this paper I consider arguments for and against the Asymmetry Thesis: the thesis that such virtual actions are never wrong. I also explain how the truth of the Asymmetry Thesis is closely aligned with the possibility of what Edward Castronova has called closed synthetic worlds. With some qualifications, the ultimate conclusion is that the Asymmetry Thesis is false and that these closed worlds are impossible.  相似文献   

Oatmeal facials and sock wrestling: the perils and promises of extra-curricular strategies for ‘fixing’ boys' education   总被引：1，自引：0，他引：1  

Marcus B. Weaver-Hightower 《Discourse: Studies in the Cultural Politics of Education》2010,31(5):683-697

Advocates for boys' education have forwarded numerous ‘fixes’ for boys' supposed educational woes, including both academic and non-academic programs and strategies. This article focuses on the lesser-discussed non-academic, extra-curricular means suggested, specifically outdoor education. Using qualitative analysis of an Australian school's outdoor education program, I demonstrate that outdoor and other non-academic sites and strategies for addressing boys' education have particular gendered dangers alongside progressive possibilities. The dangers include reproducing dominant masculinist gender regimes through social interaction, requirements for gendered self-disclosure, and philosophies of the ‘uses’ of nature. Progressive possibilities, conversely, include re-imagining outdoor education as a space for explicit resistance to gender or reimagining the uses of nature to eschew gender altogether.  相似文献   

Producing caring qualified teachers: An exploration of the influence of pre-service teacher concerns on learner-centeredness     

Karee E. Dunn  Glenda C. Rakes 《Teaching and Teacher Education》2010

In a time where students in the United States academic performance continues to lag behind in the international rankings, a disconcerting phenomenon in concerns literature indicates that pre-service and in-service teachers report low levels of concerns regarding the effect implementation of educational innovations have on students. This study explored the relationship of pre-service teachers' learner-centeredness and their concerns related to how learner-centered education affects students. Results indicated that as learner-centeredness increased, so did concerns about student outcomes. Implications for teacher education programmes in the US and abroad will be discussed.  相似文献

The impact of high-stakes testing on student proficiency in low-stakes subjects: Evidence from Florida's elementary science exam     

Marcus A. Winters  Julie R. Trivitt  Jay P. Greene 《Economics of Education Review》2010,29(1):138-146

An important criticism of high-stakes testing policies – policies that reward or sanction schools based on their students’ performance on standardized tests – is that they provide schools with an incentive to focus on those subjects that play a role in the accountability system while decreasing attention to those subjects that are not part of the program. This paper utilizes a regression discontinuity design to evaluate the impact of Florida's high-stakes testing policy on student proficiency in the low-stakes subject of science. We confirm prior results that students in schools facing more immediate sanctions under the policy made substantial gains in the high-stakes subjects of math and reading. Contrary to the crowding-out hypothesis, we find that students in these schools made substantial achievement gains in the low-stakes subject of science as well.  相似文献   

The double back salto dismount from the parallel bars     

Gervais P  Dunn J 《Sports biomechanics / International Society of Biomechanics in Sports》2003,2(1):85-101

The purpose of this study was to identify those mechanical determinants or their trends that distinguished a gymnast's best performance of the double back salto dismount on parallel bars from those judged to be inferior. Dismounts, in the tucked position, by nine Canadian gymnasts were analysed. Unique to this study was the inclusive analysis of multiple performances of the same skill by these athletes. It was felt that within-subject comparisons would reveal the kinematic variables on which the gymnast may focus in order to achieve their best performances. A non-parametric median sign test was used to compare mechanical variables, within subjects, between the dismount judged the best and those dismounts awarded a lower score. Three judges judged each dismount. In comparison to poorer performances of the dismount, statistical analyses revealed that athlete's best performances were characterised by (1) a higher release point, more vertical velocity yet with less angular momentum at take-off, (2) greater height, with a tighter and earlier tuck position during the flight phase, and (3) a greater range of motion and a more compact squat position at landing (all p's < .06).  相似文献

Defining and assessing medical informatics competencies     

Blumenthal JL  Mays BE  Weinfeld JM  Banks MA  Shaffer J 《Medical reference services quarterly》2005,24(2):95-102

As academic health sciences libraries assume larger roles in informatics instruction within medical school curricula, librarians are challenged to develop useful and accurate measures for assessing the effectiveness of instructional approaches. The need for this evaluation has intensified as medical schools increase their emphasis on integration of curriculum content and shift to competency-based education and assessment of medical students. This paper reports on a pilot project developed at Dahlgren Memorial Library, Georgetown University Medical Center, for two courses using an instructional intervention and tailored assignment for assessing student competencies.  相似文献   

The impact of the supporters’ trust movement on women’s feelings and practices of their football fandom     

Carrie Dunn 《Soccer & Society》2017,18(4):462-475

This article looks at the ways in which female football fans in England have responded to and become involved in the cooperative supporters’ trust movement. It examines the history and development of the movement, which offers a new, democratic and equitable way for supporters to become involved in the life of their club, and become part of a new, wider fan community, broader than simple club allegiance. The involvement of respondents in the supporters’ trust movement is explored, profiling the ways in which they have immersed or distanced themselves from the trust concept and community, and comparing their experiences as they have described them in interview. I argue that the trust movement offers the opportunity for supporters to help the game progress in a way that is advantageous to all fans, not just females; and this seems to be an element of the movement that has great appeal to women.  相似文献
