It is widely recognized that interdisciplinary collaboration in science is crucial to the success of the research endeavor, but that long‐established institutional structures based on a firm division of the disciplines tend to make such teamwork difficult to achieve in practice. The development of the Wiley Interdisciplinary Reviews publishing model highlights some of the opportunities and challenges of crossing these traditional lines of demarcation.  相似文献

The nuclear engineer emerged as a new form of recognised technical professional between 1940 and the early 1960s as nuclear fission, the chain reaction and their applications were explored. The institutionalization of nuclear engineering—channelled into new national laboratories and corporate design offices during the decade after the war, and hurried into academic venues thereafter—proved unusually dependent on government definition and support. This paper contrasts the distinct histories of the new discipline in the USA and UK (and, more briefly, Canada). In the segregated and influential environments of institutional laboratories and factories, historical actors such as physicist Walter Zinn in the USA and industrial chemist Christopher Hinton in the UK proved influential in shaping the roles and perceptions of nuclear specialists. More broadly, I argue that the State-managed implantation of the new subject within further and higher education curricula was shaped strongly by distinct political and economic contexts in which secrecy, postwar prestige and differing industrial cultures were decisive factors.

In this study, we examined the relations between biological maturity status, body mass index, age, and perceptions of adult autonomy support in the context of youth soccer. A total of 70 female and 43 male soccer players, aged 9 - 15 years, completed three adult-specific versions (i.e. mother, father, coach) of the perceived autonomy support subscale from the Interpersonal Style Scale. The participants' percent predicted adult stature was used as an estimate of biological maturity status. Multiple linear regression analyses revealed that advanced maturity status in male players predicted lower perceptions of autonomy support from the coach. Maturity status was unrelated to perceptions of autonomy support from the coach in female soccer players, and paternal and maternal autonomy support in male and female players. Age and body mass index were unrelated to perceptions of adult (i.e. coach, mother, father) autonomy support in male and female players.  相似文献

By manipulating stimulus variation in terms of opponent pitcher actions, this study investigated the capability of expert (n = 30) and near-expert (n = 95) professional baseball batters to adapt anticipation skill when using the video simulation temporal occlusion paradigm. Participants watched in-game footage of two pitchers, one after the other, that was temporally occluded at ball release and various points during ball flight. They were required to make a written prediction of pitch types and locations. Per cent accuracy was calculated for pitch type, for pitch location, and for type and location combined. Results indicated that experts and near-experts could adapt their anticipation to predict above guessing level across both pitchers, but adaptation to the left-handed pitcher was poorer than the right-handed pitcher. Small-to-moderate effect sizes were found in terms of superior adaptation by experts over near-experts at the ball release and early ball flight occlusion conditions. The findings of this study extend theoretical and applied knowledge of expertise in striking sports. Practical application of the instruments and findings are discussed in terms of applied researchers, practitioners and high-performance staff in professional sporting organisations.  相似文献

This article utilizes Walter Benjamin’s concept of the dialectical image to contextualize racial narratives in the contemporary United States. It examines techniques employed by the National Basketball Association (NBA) in the racial packaging of its product, which includes the selection of commentators, the content of commentary, the NBA’s dress code and the NBA’s minimum age requirement. Following this packaging, the NBA then projects the resulting commodification of black masculinity to its fans as phantasmagoria. Moving beyond a critique of these phantasmagorical racial narratives, this article incorporates the NBA’s commodification of black masculinity within a dialectical image that also includes written and visual texts found within the reactions to the fatal shooting of Trayvon Martin. This dialectical image is used to illuminate tensions that carefully packaged racial narratives such as those found in the NBA attempt to keep hidden.  相似文献

Sports science research is traditionally monodisciplinary despite calls for an interdisciplinary focus. The primary purpose of this systematic review was to identify studies on talent identification, talent selection and competition performance to determine whether interdisciplinary research is being conducted. Thirty-six studies met the selection criteria. These studies were critiqued relative to sport, skill level, sport science sub-disciplines included, and whether the research was multidisciplinary or interdisciplinary. The secondary purpose of the review was to critique the level of analysis and level of representative task design in performance tests used in the studies. Twenty-five studies were categorised as interdisciplinary, with 11 categorised as multidisciplinary. Thirteen sports were represented with soccer the most frequent followed by field hockey, Australian Rules football, handball and rugby league. Thirty-two studies completed their analysis at a group level and four at an individual level. A total of 337 performance tests were rated for representative task design with 64 categorised as low, 123 as medium and 150 as high. The results pertaining to interdisciplinary studies and individual analyses are discussed in relation to constraints theory, which predicts that interacting variables can explain sport performance. Sports science research is beginning to fulfil the call for interdisciplinary research. Future research, however, needs to consider individual analyses and representative task design of tests to progress sports science knowledge.  相似文献

The purpose of this study was to examine whether retention of kindergarten and first-grade children is associated with long-term beneficial effects. Thirty-one children who had been retained were compared to 31 children who had similar grades but had never been retained. The dependent measures were grade point average in the second through fifth grades and four teacher-assessed areas of functioning in the fourth and fifth grade: social competence, cognitive competence, externalizing problems, and internalizing problems. The results indicated that retention was not associated with long-term beneficial effects but rather, especially for White children, appeared to be associated with poorer academic and social functioning. Implications and limitations of the study are discussed.  相似文献

Abstract

Primary Education is seen as a critical element for general improvement of the economic and social future of Honduras and the most significant action currently underway is the work being done through the Primary Education Efficiency Project which is financed by a major grant from the United States Agency for International Development (USAID). The Project has as its major objective the improvement of the quality of educational services at the primary level through the development of new textbooks for grades one through six and extensive in‐service teacher training which is described here. This article presents the three essential elements of a specific training implemented; the contents, the media to be used and the methodology for its delivery. The medium chosen for the training was a printed document in a newspaper format which was given the name Accion Educativa. The general reaction from the teachers to this form of presentation was highly positive and the success of the use of the print medium led to the conclusion that the project should continue using similar publications, and should study the possibility of establishing Accion Educativa as a monthly periodical for primary school teachers.
