Effects from audit culture and neoliberalism on university teaching: an autoethnographic perspective
Spanish university culture revolves mainly around the evaluation of professionals on the basis of the amount of work published in high-impact journals (weight assessments). The paper is shaped as an autoethnography, focusing mainly on the author’s life at university. Data collection and analysis set off from 2011, during the lecturer’s first year of working at university. The research aims principally at reflecting upon the highly demanding processes undergone by a lecturer, which might have a negative impact on other personal and professional domains. However, we also seek to show the weaknesses of the accreditation system as well as to consider the need to design a system that is able to put the emphasis back on the value of real academic work. 相似文献

Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets. Changes in daily steps (average of steps taken during six consecutive days), six-minute walk test (6MWT), health-related quality of life, asthma control and anxiety and depression levels were assessed 12 weeks after intervention and 24–28 weeks after randomization. Thirty-seven participants were recruited and 30 completed the intervention. At 12 weeks, the groups differed significantly in daily steps (adjusted average difference, 2488 steps; 95% confidence interval [CI], 803 to 4172; p = 0.005) and in the 6MWT (adjusted average difference, 21.9 m; 95% CI, 6.6 to 37.3; p = 0.006). These differences were not significant 24–28 weeks after randomization. The program was effective in increasing daily steps of adults with moderate to severe asthma 12 weeks after intervention. 相似文献

This study was conducted to determine the effects of inspiratory muscle training (IMT) on respiratory and peripheral muscles oxygenation during a maximal exercise tolerance test and on repeated-sprint ability (RSA) performance in professional women football players. Eighteen athletes were randomly assigned to one of the following groups: SHAM (n = 8) or IMT (n = 10). After a maximal incremental exercise test, all participants performed (on a different day) a time-to-exhaustion (Tlim) test. Peripheral and respiratory muscles oxygenation by near-infrared spectroscopy, breath-by-breath ventilatory and metabolic variables, and blood lactate concentration were measured. The RSA test was performed on a grass field. After a 6 week intervention, all athletes were reevaluated. Both groups showed increases in inspiratory muscles strength, exercise tolerance and RSA performance, however only the IMT group presented lower deoxyhemoglobin and total hemoglobin blood concentrations on intercostal muscles concomitantly to an increased oxyhemoglobin and total hemoglobin blood concentrations on vastus lateralis muscle during Tlim. In conclusion, these results may indicate the potential role of IMT to attenuate inspiratory muscles metaboreflex and consequently improve oxygen and blood supply to limb muscles during high-intensity exercise, with a potential impact on inspiratory muscle strength, exercise tolerance and sprints performance in professional women football players. 相似文献

The aim of this article is to analyse how 15 students at a public elementary school detach from immobile representations of identity through aesthetic self-expressive work with cinema. Drawing on Deleuze and Guattari’s concept of assemblage, I interrogate students’ experiences of discrimination and challenge their processes of developing a short film within cinema workshops at school. I find that when new components regarding cinema, such as material apparatuses (e.g. cameras, stages, sound recorders) and expressive devices (e.g. improvisation, dialogues, corporeal movements), are applied to both the school and subjectivities, there is a rupture of rigid systems of representation and the creation of novel assemblages. 相似文献

The purpose of this study is to assess the effectiveness of the Texas “Closing the Gaps by 2015” plan to increase Hispanic enrollment into and graduation from institutions of higher education. This study uses Interrupted Time Series with Comparison Group to analyze 26 years of student cohorts in Texas universities. Controlling for historical enrollment and graduation growth as well as population growth, the results show that Hispanic college enrollment significantly increased as a result of the plan, but graduation did not. Several recommendations are offered for those states that wish to emulate Texas policies of increasing college enrollment and graduation of Hispanics. 相似文献

AbstractThis study investigated the influence of the regression model and initial intensity during an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and performance in elite-standard runners. Twenty-three well-trained runners completed a discontinuous incremental running test on a treadmill. Speed started at 9 km · h?1 and increased by 1.5 km · h?1 every 4 min until exhaustion, with a minute of recovery for blood collection. Lactate–speed data were fitted by exponential and polynomial models. The lactate threshold was determined for both models, using all the co-ordinates, excluding the first and excluding the first and second points. The exponential lactate threshold was greater than the polynomial equivalent in any co-ordinate condition (P < 0.001). For both models, the lactate threshold was lower when all co-ordinates were used than when the first and the first and second points were excluded (P < 0.001). 10-km race pace was correlated with both the exponential and polynomial lactate thresholds for all the co-ordinate conditions (r ≥ 0.75, P < 0.001 and r ≥ 0.56, P < 0.05, respectively). The results suggest that the exponential lactate threshold should be used instead of the polynomial equivalent since it is more strongly associated with performance and is independent of the initial intensity of the test. 相似文献

AbstractExercise performed at a competitive level could deeply modify the immune system and the cytokine response of athletes. In this report, we demonstrated that young elite female artistic gymnasts (n = 16; age: 9–15 years) showed an increase of interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-α) mRNA expression in blood mononuclear cells (PBMCs), in comparison to girls performing the same sport at a recreational level (n = 16; age: 10–15 years). The increase of IL-6 and TNF-α mRNAs appeared to be directly linked to the intensity and duration of the training. Moreover, in elite athletes engaged in artistic gymnastics or in synchronised swimming (n =34; age: 9–15 years), IL-6 gene expression appeared to be modulated by the levels of circulating oestrogens: pre-pubertal athletes (n = 20; age: 11 ± 1 years) revealed a higher increase in IL-6 than pubertal athletes (n = 14; age: 14 ± 1.6 years). In pre-pubertal athletes, body mass index (BMI) percentile was inversely correlated with the increase of both IL-6 and TNF-α. The consequence of these events was the shift of the cytokine profile towards a pro-inflammatory status. These modifications, induced by training performed at an elite level, might negatively affect the growth of female children athletes. 相似文献

AbstractDespite a wide international literature on the effect of vocational and general education on school-to-work transition, relatively little is known about the role of having studied specific subjects in explaining inequalities in young people’s labour market outcomes. This paper aims to fill this gap by examining differences in employment chances of young people who left education early, either at the end of compulsory schooling or at the end of secondary school. Using data from the Scottish Longitudinal Study, a large-scale linkage study created using data from administrative and statistical sources, we found little gender differences but strong parental background differences in school leavers’ employment status and type of occupation entered. Social inequalities in labour market outcomes were only partly explained by curriculum choices. Moreover, after controlling for social origin and grades, only history and business for lower-secondary leavers and maths for upper-secondary leavers were associated with a reduction in the chances of being unemployed/inactive. 相似文献

In two experiments, rats received preexposure consisting of six intraperitoneal injections of lithium chloride (LiCl). This
treatment reduced the magnitude of the unconditioned response (UR; suppressed consumption of a novel flavor) evoked by an
additional injection (Experiment 1) or by oral consumption (Experiment 2) of LiCl. In both experiments, preexposure also attenuated
the acquisition of a conditioned aversion with an LiCl injection as the unconditioned stimulus (US) but had no effect on the
aversion produced when the US was oral consumption of LiCl (Experiment 2). These results are consistent with the view that
the reduced ability of the preexposed US to serve as a reinforcer depends on blocking by injection-related cues and is independent
of habituation of the UR recorded in the present study. Possible interpretations of this dissociation are discussed. 相似文献
