ABSTRACTExcellence has become a ‘hoorah’ word which is widely used in higher education institutions to legitimate practices related to the recruitment/progression of staff. It can be seen as reflecting an institutionalised belief that such evaluative processes are unaffected by the social characteristics of those who work in them or their relationships with each other. Such views have been challenged by gender theorists and by those researching informal power in state structures. The purpose of this article is to raise the possibility that excellence is an ‘idealised cultural construct’ and a ‘rationalising myth’. Drawing on data from qualitative interviews with 67 men and women, who were candidates or evaluators in recruitment/progression processes in five higher educational institutions (in Ireland, Turkey, Bulgaria, Germany and Italy), it conceptualises and illustrates masculinist, relational and ‘local fit’ micro-political practices that are seen to affect such recruitment/progression. Variation exists by gender and by contextual positioning in the process (i.e. as evaluator/candidate). These practices illustrate the perceived importance of the enactment of informal power. The article suggests that the construct of excellence is used to obscure these practices and to maintain organisational legitimacy in the context of multiple stakeholders with conflicting expectations. 相似文献

Food-deprived rats that receive intermittent delivery of small amounts of food develop excessive drinking--specifically, schedule-induced polydipsia (SIP). A main characteristic of SIP is its occurrence at the beginning of interfood intervals. The purpose of this study was to demonstrate that SIP can be developed toward the end of interfood intervals, in closer proximity to upcoming than to preceding food delivery. In Experiment 1, two groups were exposed to a fixed-time (FT) 30-sec food schedule with water available during the first or the last 15 sec of each interfood interval. Two additional groups, which had access to water throughout, were exposed to FT 30-sec or FT 15-sec schedules of food presentation. The FT 30-sec group with free access to water developed the highest level of intake; similar and intermediate levels were induced in all the remaining groups. In Experiment 2, three groups of rats were exposed to an FT 90-sec food schedule with water available during the first, the second, or the last 30 sec of each interfood interval. One additional group with access to water throughout was exposed to the FT 90-sec schedule of food presentation. The group with free access to water developed a higher level of consumption than did the other groups, but by the end of training none of the four groups showed statistical differences in polydipsic drinking. Results show that adjunctive drinking can be developed in proximity to upcoming food delivery even with long interfood intervals. 相似文献

In this article, I study, from the point of view of the analytic philosophy of mind, the compatibility of students’ ideas studies (SIS) with radical constructivism (RC). I demonstrate that RC is based on a psychology of narrow mental states; that is, the idea that the mental content of an individual can be fully characterised without any reference external to her or him. I show that this fact imposes some severe restrictions to SIS to be incorporated into RC. In particular, I argue that only qualitative studies can comply with the requirement of narrowness. Nevertheless, I propose that quantitative works can be employed as sources of types in order to study token actual students. I use this type-token dichotomy to put forward an outline of a theory of the relation between school contents and mental contents. In this view, token mental contents regarding a given topic can be defined, and probed, only by resorting to typical school contents. 相似文献

Via the existential questioning outlook supplied by the Grasshopper’s three visions as relevant to the fate of humankind – oblivion, delusion, and really magnificent games – this article seeks to alleviate some of the ambiguity surrounding Bernard Suits’ provocative claim that Utopian existence is fundamentally concerned with game-playing. Specifically, after proposing an interpretation of Suits’ parable designed to enrich the logical intelligibility of his Utopian thesis, I advance the suggestion that the Grasshopper’s picture of people playing really magnificent games is reasonably interpreted as a clue that the philosopher’s quest to discern games worthy of a Utopian might very well be that which saves humanity from the desolate oblivion-delusion paradox erected as a consequence of the initial two visions. 相似文献

The aim of this study was to describe and compare the EMG patterns of select lower limb muscles throughout the golf swing, performed with three different clubs, in non-elite middle-aged players. Fourteen golfers performed eight swings each using, in random order, a pitching wedge, 7-iron and 4-iron. Surface electromyography (EMG) was recorded bilaterally from lower limb muscles: tibialis anterior, peroneus longus, gastrocnemius medialis, gastrocnemius lateralis, biceps femoris, semitendinosus, gluteus maximus, vastus medialis, rectus femoris and vastus lateralis. Three-dimensional high-speed video analysis was used to determine the golf swing phases. Results showed that, in average handicap golfers, the highest muscle activation levels occurred during the Forward Swing Phase, with the right semitendinosus and the right biceps femoris muscles producing the highest mean activation levels relative to maximal electromyography (70–76% and 68–73% EMGMAX, respectively). Significant differences between the pitching wedge and the 4-iron club were found in the activation level of the left semitendinosus, right tibialis anterior, right peroneus longus, right vastus medialis, right rectus femuris and right gastrocnemius muscles. The lower limb muscles showed, in most cases and phases, higher mean values of activation on electromyography when golfers performed shots with a 4-iron club. 相似文献

The aims of the present study were to assess the association of environmental perception with objective and self-reported physical activity (PA) and the relation between environmental perception and meeting PA recommendations on children and adolescents. A sample of 1520 youth (770 boys) aged 8–18 years (12.1 ± 2.5 years) from the UP&;DOWN study were included in the data analyses. Environmental perception was assessed with the short adapted version of the ALPHA environmental questionnaire. PA was objectively (accelerometers) and self-reported measured (PA Questionnaire for Children, Patient-centered Assessment and Counseling for Exercise Questionnaire and Finnish PA Index). Linear regression models were used to assess the association of environmental perception with PA. Bivariate logistic regression models were used to assess differences between environmental perception and meeting PA recommendations. Environmental perception was positively associated with both objective and self-reported PA. Some differences were found in the association of environmental perception and PA between sex- and age-specific groups. Youth who perceived a more favourable environment were more likely to meet PA recommendations (at least 60 min · day?1 of moderate to vigorous PA (MVPA)). Results suggest that environmental perceptions of children and adolescents may play an important role in achieving higher levels of PA. 相似文献

AbstractIn this article, we study the evolution of competitive sport and sporting recreations in medieval Córdoba, from the Umayyad Muslims (756–1236) to the Christians (since 1236). In this diachronic study, firstly we compare the competitive sport and sporting recreations of the Muslim East (especially those of the Abbasid period) with those of Muslim Córdoba, in order to know the level of Arabization of those practices in Córdoba, and if competitive sport is more predominant than recreations or vice versa. Secondly, we study if competitive sport and sporting recreations had the same presence in Muslim Córdoba and Christian Córdoba (or if one predominated over the other), and the possible reasons for it. We conclude: (1) that in Muslim Córdoba, sporting recreations were more important than competitive sport, unlike what happened in the great Muslim cities of the East; (2) Arabization is almost total regarding the types of sport and recreations implanted in Córdoba but low regarding horse sports and the importance of competitive sport; and (3) that Christian Córdoba shows a very different character, since competitive sport is very important (largely because by that time Córdoba had become a frontier city). 相似文献

This paper examines the use of sensor devices in sports biomechanics, focusing on current frequency of use of Electromyography (EMG) device preferences. Researchers in the International Society of Biomechanics in Sports were invited to participate in an online survey. Responses on multiple sensor devices highlighting frequency of use, device features and improvements researchers sought in acquisition and analysis methods were obtained via an online questionnaire. Results of the investigation showed that the force platform is the most frequently used device, with inertial measurement units and EMG devices growing in popularity. Wireless functionality and ease of use for both the participant and the practitioner proved to be important features. The main findings of the survey demonstrated need for a simple, low power, multi-channel device which incorporates the various sensors into one single device. Biomechanists showed they were looking for more availability of wireless sensor devices with acquisition and analysis features. The study found there is a need to develop software analysis tools to accompany the multi-channel device, providing all the basic functions while maintaining compatibility with existing systems. 相似文献

Objectives: The main aim of this study was to compare the bone mass of female football players with controls of different pubertal stages. Methods: Sixty five girls aged 8–14 years (10.14?±?0.1, Tanner stages I–IV) participated in the study. Twenty participants were prepubertal (10 prepubertal control) and 45 peripubertal (15 peripubertal control). All footballers trained two days per week while the control group did not perform regular physical activity outside of school. Body composition was assessed by Dual-energy X-ray absorptiometry. Analysis of covariance was performed to evaluate differences in lean and bone masses. Results: Significant differences in lower-body extremities lean mass (LLM) between peripubertal groups were found (P?.05). Additionally, prepubertal footballers showed higher values of bone mineral content (BMC) at the femoral neck (P?.05) while peripubertal footballers exhibited enhanced BMC at the whole-body, trochanter and Wards triangle area. Bone mineral density (BMD) was higher in footballers compared to their non-active peers at the femoral neck and intertrochanter (P?.05, respectively) while in the peripubertal footballers higher BMD values were found in almost all of the studied body sites. Conclusion: Female footballers showed higher bone and lean masses compared to control counterparts; these differences are already detectable at prepubertal ages and more consistent after pubertal spurt. 相似文献
