Much has been written about the remarkable rise of global university rankings from their initial appearance in the Academic Ranking of World Universities (Shanghai) tables in 2003. The examination of all things rankings, however, has arguably outpaced its conceptual uptake. This paper addresses this imbalance by reviewing prestige audits as resource management tools and status allocation measures. The paper argues that audit ambition has courted audit failure in both dimensions. The resource management justification underestimates the challenge of devising reliable proxy variables across international higher education sectors, organizational types, and disciplinary/departmental objectives. Evidential data sets are duly recast as data narratives that compete with each other and cloud the ordinal clarity aspired to in ranking tables. The status competition approach generates Matthew effects and encourages factor gaming. Positional goods investments are also socially and economically wasteful. In either strict (rigid) or relaxed (normed) form, finally, their zero-sum logic fails to account for private and public externalities. The paper closes with an appeal to soft-variable evaluations in higher education contexts as well as to closer scrutiny of the vocabulary informing both quantitative and qualitative assessments. 相似文献

This study takes an individual differences' perspective on performance feedback effects in psychometric testing. A total of 105 students in a mainstream secondary school in North East England undertook a cognitive ability test on two occasions. In one condition, students received item-specific accuracy feedback while in the other (standard condition) no feedback was provided. While accuracy feedback had, on average, no effect on test performance, differential effects were observed. Performance goal orientation and self-confidence moderated feedback effects on performance. The provision of accuracy feedback seemed to have performance optimising effects upon test takers with high performance goal orientation in combination with low self-confidence. The implications of these findings in relation to the validity of findings from psychological testing are discussed. 相似文献

To successfully generate more valuable technologies from accessing basic research knowledge, firms need to combine institutional and individual level bridges to universities and research institutes active in basic research. This combination is particularly important when the new technology builds on scientific prior art. While mobile inventors are needed to transfer and translate basic knowledge into new technologies, partnerships provide the commitment, resources and incentive structure to integrate this basic research knowledge more effectively into the firm’s innovation process, thus improving the value capture from mobile inventors. Our findings in the micro-electronics field illustrate the importance of jointly accounting for firm and inventor level industry-science links to assess their effectiveness and provides evidence on complementarity from using both. Furthermore, identifying the scientific nature of the technology projects critically determines whether the combination of these links allow to capture more value. 相似文献

This study investigated the associations between fundamental athletic movement and physical fitness in junior Australian football (AF). Forty-four under 18 players performed a fundamental athletic movement assessment consisting of an overhead squat, double lunge, single leg Romanian deadlift and a push up. Movements were scored on three assessment criterions using a three-point scale. Additionally, participants performed five physical fitness tests commonly used for talent identification in AF. A Spearman’s nonparametric correlation matrix was built, with correlation coefficients being visualised using a circularly rendered correlogram. Score on the overhead squat was moderately positively associated with dynamic vertical jump height on left (rs = 0.40; P ≤ 0.05) and right (rs = 0.30; P ≤ 0.05) leg take-off, stationary vertical jump (rs = 0.32; P ≤ 0.05) and negatively associated with 20-m sprint time (rs = ?0.35; P ≤ 0.05). Score on the double lunge (left/right side) was moderately positively associated with the same physical fitness tests as well as score on the multistage fitness test. Results suggest that improvements in physical fitness qualities may occur through concurrent increases in fundamental athletic movement skill, namely the overhead squat and double lunge movements. These findings may assist with the identification and development of talent. 相似文献

ABSTRACTThis article considers ideas about the performance of personal stories in stand-up comedy that emerged during a teaching and performance project in a refugee camp in Palestine. After experimenting with a range of stand-up techniques and approaches, participants created public performances sharing their experiences of life under military occupation. 相似文献

Abstract This study was designed to determine if the skinfold measurements on an exercised arm would decrease as a result of regular weight training with that arm. Thirty-two subjects completed three sets of 7-RM curls and three sets of 7-RM triceps extensions on either a daily or an alternate day schedule for a period of 6 weeks. The nonexercised arm was measured to establish the specificity of the spot reduction on the exercised arm. The results indicate that hard exercise in a specific area of the arm will result in a reduction of the subcutaneous adipose tissue in that area. 相似文献

Abstract The aim of this study was to assess the capability of the 3dNX? accelerometer to predict energy expenditure in two separate, free-living cohorts. Twenty-three adolescents and 14 young adults took a single dose of doubly labelled water and wore a 3dNX? activity monitor during waking hours for a 10-day period while carrying out their normal routines. Multiple linear regression with backward elimination was used to establish the strength of the associations between various indices of energy expenditure, physical activity counts, and anthropometric variables. 3dNX? output accounted for 27% and 35% of the variance in the total energy expenditure of the adolescent and young adult cohort, respectively. The explained variance increased to 78%, with a standard error of estimate of 7%, when 3dNX? output was combined with body composition variables. The 3dNX? accelerometer can be used to predict free-living daily energy expenditure with a standard error of estimate of 1.65 MJ in adolescents and 1.52 MJ in young adults. The inclusion of anthropometric variables reduces the error to approximately 1 MJ. Although it remains to cross-validate these models in other populations, early indications suggest that the 3dNX? provides a useful method of predicting energy expenditure in free-living individuals. 相似文献

The study investigated differences in the one‐ (SH) and two‐handed (DH) backhands when hit flat, across‐court (AC) and down‐the‐line (DL), and with heavy topspin DL (TDL). The ability to disguise each of these backhands when hitting the above strokes was also assessed. Eighteen college‐level male tennis players, identified as having a high performance topspin SH (n = 6) or DH (n = 12) backhand drive, participated in the study. Players were required to hit three AC, DL and TDL backhands from the baseline with their preferred technique, while being filmed with two high‐speed video cameras operating at 200 Hz. The highest horizontal velocity backhand for each stroke was analysed. Results indicated that the sequential coordination of five body segments (hips, shoulder, upper arm, forearm, and hand/racquet rotations) was required for the execution of the SH stroke. The same number of segments were generally coordinated in the DH stroke (hips, shoulders, and varying degrees of upper arm and forearm rotations followed by hand/racquet movement). Mature players produced comparable racquet horizontal velocities 0.005 s prior to impact using either the SH or DH backhand technique. The SH backhand was characterised by a more rotated shoulder alignment than the DH stroke (SH: 119.1°; DH: 83.4°) at the completion of the backswing. At impact the ball was impacted further in front (SH: 0.59 m; DH: 0.40 m) and a similar distance to the side of the body (SH: 0.75 m; DH: 0.70 m). Players using the DH backhand technique delayed the horizontal acceleration of the racquet towards the ball (SH: 0.13 s; DH: 0.08 s prior to impact) and thus were capable of displaying a similar hitting motion closer to impact than players with a SH technique. 相似文献
