A randomized trial comparing cadaveric dissection and examination of prosections as applied surgical anatomy teaching pedagogies

Anatomy is an important component in the vertical integration of basic science and clinical practice. Two common pedagogies are cadaveric dissection and examination of prosected specimens. Comparative studies mostly evaluate their immediate effectiveness. A randomized controlled trial design was employed to compare both the immediate and long-term effectiveness of dissection and prosection. Eighty third-year medical students undergoing their surgical rotation from the Yong Loo Lin School of Medicine were randomized into two groups: dissection and prosection. Each participated in a one-day hands-on course following a similar outline that demonstrated surgical anatomy in the context of its clinical relevance. A pre-course test was conducted to establish baseline knowledge. A post-course test was conducted immediately after and at a one-year interval to evaluate learner outcome and knowledge retention. A post-course survey was conducted to assess participant perception. Thirty-nine and thirty-eight participants for the dissection and prosection groups, respectively, were included for analysis. There was no significant difference between mean pre-course test scores between the dissection and prosection groups [12.6 (3.47) vs. 12.7 (3.16), P > 0.05]. Both the mean immediate [27.9 (4.30) vs. 24.9 (4.25), P < 0.05] and 1 year [23.9 (4.15) vs. 19.9 (4.05), P < 0.05] post-course test scores were significantly higher in the dissection group. However, when adjusted for course duration [dissection group took longer than prosection group (mean 411 vs. 265 min)], these findings were negated. There is no conclusive evidence of either pedagogy being superior in teaching surgical anatomy. Based on learner surveys, dissection provides a greater learner experience.     

Technology and adolescents: Perspectives on the things to come

Assuming that, given the processes of technology diffusion, adolescent behavior forecasts future consumption of digital information, it would seem pertinent to study the characteristics of teenager technology use. This research asks: What are the key patterns regarding the use of technology platforms by teenagers? Is technology usage among teenagers shaped by schools' disparate teaching philosophies and cultures? How is technology usage impacting the consumption of traditional print media? A survey designed to determine how high school students use technology was administered at a private boarding school in New Hampshire and a public school in New York. The research concluded that individuals' residing environment and context shape ICT adoption. School culture and geographic context drive behavioral technology usage patterns. Furthermore, consumption of information appears to be guided by a principle of complementarity. However, technology substitution should not be discarded. Finally, school culture incorporating and promoting technology use may contribute positively to knowledge acquisition, although technology adoption without controls could negatively impact the teaching experience. While directionally valid, the study results need to be validated by statistical research and case studies.     

The Virtual Culture Industry: Work and Play in Virtual Worlds

This essay uses Horkheimer and Adorno's work on the culture industry to analyze virtual worlds and massively multiplayer online role-playing games. While artificial worlds have enormous potential to facilitate communication, transcend spatial boundaries, promote free expression, and protect marginalized groups, the utopian promise of these worlds is undermined by their mirroring of real-world market systems, the exploitation of labor, and blurring the line between entertainment and work. The culture industry thesis provides a useful starting point for theorizing virtual worlds and explaining why these places have become mirrors of real-world economic relations.     

Cricket

In this study we analysed technique, ball speed and trunk injury data collected at the Australian Institute of Sport (AIS) from 42 high performance male fast bowlers over a four year period. We found several notable technique interrelationships, technique and ball speed relationships, and associations between technique and trunk injuries. A more front‐on shoulder alignment at back foot contact was significantly related to increased shoulder counter‐rotation (p < 0.001). Bowlers who released the ball at greater speeds had an extended front knee, or extended their front knee, during the front foot contact phase (p < 0.05). They also recorded higher braking and vertical impact forces during the front foot contact phase and developed those forces more rapidly (p ≤ 0.05). A maximum hip‐shoulder separation angle occurring later in the delivery stride (p = 0.05) and a larger shoulder rotation to ball release (p = 0.05) were also characteristics of faster bowlers. Bowlers suffering lower back injuries exhibited typical characteristics of the ‘mixed’ technique. Specifically, the hip to shoulder separation angle at back foot contact was greater in bowlers who reported soft tissue injuries than in non trunk‐injured bowlers (p = 0.03), and shoulder counter‐rotation was significantly higher in bowlers who reported lumbar spine stress fractures than non trunk‐injured bowlers (p = 0.01). The stress fracture group was also characterised by a larger hip angle at front foot contact and ball release, whereas a more flexed front knee at ball release characterised the non trunk‐injured group.     

Anthropometric characteristics of elite cricket fast bowlers

Abstract

The aims of this study were to describe the current anthropometric profiles of elite Australian female and male cricket fast bowlers and establish a set of reference values useful for future investigations on player selection, talent identification, and training programme development. The participants were 26 female (mean age 22.5 years, s = 4.5; height 1.71 m, s = 0.05; body mass 66.2 kg, s = 7.5) and 26 male (mean age 23.9 years, s = 3.5; height 1.88 m, s = 0.05; body mass 87.9 kg, s = 8.2) fast bowlers. The anthropometric profiles included the measurement of skinfolds, and segment lengths, breadths, and girths. A series of derived variables assessing the distribution of subcutaneous adipose tissue, the bivariate overlap zone, relative body size and proportionality, and somatotype were also calculated. The male bowlers had larger length, breadth, and girth measurements than their female counterparts. There were differences in proportionality between the sexes, with only the male bowlers exhibiting characteristics that could be considered “large” relative to height. The female bowlers had a higher sum of seven skinfolds (P < 0.001), were more endomorphic (F _1,50 = 30.18, P < 0.001), and less mesomorphic (F _1,50 = 10.85, P < 0.01) than the male bowlers. These reference data should be useful to practitioners and researchers interested in cricket. Further research is needed to clarify why only male fast bowlers had variables that were proportionally large relative to height.     

The Pursuit of Regional Geopolitical Aspirations: China's Bids for the Asian Games and the Asian Winter Games since the 1980s

Any international bid involves a zero-sum competition among two or more national candidates vying for the right to host a particular international event. Chinese cities in total have participated in the Asian Games and Asian Winter Games bids four times since 1980. Beijing's bid for the 1990 Asian Games; Harbin's bid for the 1996 Asian Winter Games; Changchun's bid for the 2007 Asian Winter Games and Guangzhou's bid for the 2010 Asian Games: not one encountered failure. The argument here is that all the bids were used to build up China's hegemonic status in the Asian sports community with wider resonances for the geopolitical hegemonic influence of China. Evidence is drawn from contemporary literature and media reports.     

Strict Compliance!: Chinese Careful Conformity and the Guangzhou Bid for the Asian Games

This article aimed to examine whether the division of labour between the Chinese central and local officials, who came from the China General Sports Administration; the Chinese National Olympic Committee; and the Guangdong and Guangzhou governments, strictly complied with the stipulations of the Olympic Council of Asia in completing Guangzhou's bid for the 2010 Asian Games. The findings confirm Guangzhou as a rule-abiding bidder, and imply China's eagerness to be accepted by the international community and to project itself as a superpower in accordance with its wider political, economic and cultural ambition.     

Observed characteristics and teacher quality: Impacts of sample selection on a value added model

We measure the impact of observed teacher characteristics on student math and reading proficiency using a rich dataset from Florida. We expand upon prior work by accounting directly for nonrandom attrition of teachers from the classroom in a sample selection framework. We find evidence that sample selection is present in the estimation of the influence of teacher characteristics, but that failure to account for it does not appear to substantially bias estimation. Further, our procedure produces some evidence that more effective teachers are more likely to exit the classroom.     

Do black women still come first? Examining Essence magazine post Time Warner

Essence magazine is the longest operating magazine catering to a predominately African-American women audience in the US. In 2000, media conglomerate Time Warner purchased 49% of Essence parent company Essence Communications Inc. In 2005, Time Warner purchased the remaining 51% of the black-owned company. As a media conglomerate, Time Warner owns major publishing houses, film, and television production companies, including 130 magazines, New Line Cinema, CNN, and HBO. Essence states it is “the voice and soul of Black women” Collins [Collins, P. H. (2000). Black feminist thought: Knowledge, consciousness, and the politics of empowerment. New York, NY: Routledge] argues that black women must speak in their own voices in order to reject prevailing stereotypes operating on the bodies of black women. The mission statement of Essence aligns itself in what Collins calls “safe spaces” for black women to self-define themselves and articulate their lived realties. A critical theoretical framework allows uneven power relations to be examined and offers emancipatory perspectives. The goal of this study is to examine if Time Warner’s purchase of Essence has caused a shift in the voice and content of this magazine.
