Old Wine in old Bottles: the Neglected Role of Vocational Training Centres in Innovation     

Igone Porto Gómez  Jon Mikel Zabala-Iturriagagoitia  Urko Aguirre Larrakoetxea 《Vocations and Learning》2018,11(2):205-221

Vocational training centres are conceptually regarded as key players in the knowledge generation and dissemination processes that take place within innovation systems. However, the literature does not provide conclusive evidence of their influence on the generation, development and dissemination of innovations. The goal of this paper is to analyse whether vocational training centres are indeed relevant agents in the articulation, knowledge exchange and dissemination of a local innovation system. The paper explores the most influential agents driving cooperation and articulating the local innovation system in Durango, one of the twenty counties of the Basque Country, Spain. Social network analysis is applied to regional collaboration networks in order to address this purpose. Our results show evidence of the pivotal role played by vocational training centres within local innovation processes implemented by firms. For many local firms vocational training centres represent the main sources of knowledge in their innovation processes. In the Basque context, vocational training centres have a longer history than other knowledge infrastructures, such as universities and research centres. These long-standing centres thus constitute ‘old bottles’ that despite their history are still able to produce a ‘good old wine’ in terms of innovation, which is translated into competitive advantage for the territory. Science, technology and innovation policies should therefore not only aim to create more knowledge infrastructures, but also to reinforce the role that traditional and territorially established organizations like vocational training centres can play as intermediary agents.  相似文献   

Why We Say it Like That: Making Rhetorical Practices Explicit for Students in Disciplinary and Interdisciplinary Courses     

Jon C. Wiebel 《College Teaching》2018,66(1):24-30

Students in colleges and universities need to be able to learn how to communicate effectively both within the specialized arenas of their chosen disciplines and, increasingly, with a wide variety of public and professional audiences. One way to accomplish this goal is to integrate the development of effective writing and speaking skills into both our disciplinary and interdisciplinary classrooms. In this essay, we suggest that faculty to adopt a “rhetorical perspective” in their teaching, regardless of discipline, in order to capitalize on already existing faculty expertise and empower students. Specifically, a rhetorical perspective integrating speaking and writing can help students to become more active agents in their intellectual development, can help faculty design assignments and activities that relate directly to course goals and learning outcomes, and can provide a framework for feedback that can facilitate student learning.  相似文献   

Inflammatory and apoptotic signalling pathways and concussion severity: a genetic association study

The objective was to investigate the relationship between IL-1B rs16944, IL-6 rs1800795, and CASP8 rs3834129 genetic polymorphisms and concussion severity. Rugby players from high school, senior amateur, and professional teams completed a concussion severity questionnaire and donated a DNA sample. Participants (n = 163) were split into symptom severity groups around the median number and duration of symptoms. The frequency of participants with high symptom counts (more than five symptoms) increased across the IL-1B (C/C: 35%; C/T: 51%; T/T: 56%; P = 0.047) and the IL-6 (C/C: 31%; C/G: 44%; G/G: 58%; P = 0.027) genotypes. The C–C inferred interleukin allele construct frequency, created from combining the IL-1B and IL-6 genotype data, was lower in participants reporting a high symptom count (18%), compared to those with a low symptom count (fewer than six symptoms, 36%, P = 0.002). Similarly, the C–C inferred interleukin allele construct frequency was lower in those reporting prolonged symptom duration (more than one week, 16%), as opposed to short symptom duration (less than one week, 34%, P = 0.015). This study provides evidence of novel inflammatory pathway genetic associations with concussion severity, which supports the hypothesis implicating neuroinflammation in the development of concussion symptoms.  相似文献   

Prediction of performance by heart rate-derived parameters in recreational runners

We investigated whether heart rate (HR)-derived parameters are accurate performance predictors in endurance recreational runners. One hundred thirty recreational athletes completed an incremental running test (4´running + 1´rest). After each stage, we recorded HR, % of maximum HR (%HRmax), and blood lactate. We also assessed HR after each recovery period, and calculated lactate and HR recovery thresholds and HR deflection point. We tested these parameters for associations with running performance, as measured by peak treadmill speed (PTS) and personal best International Association of Athletics Federations (IAAF) score. The %HRmax at 14.5 km·h^?1 correlated with PTS (r = ?0.92), and IAAF score (rho = ?0.80). The magnitudes of the correlations of lactate-related parameters with PTS (|r| = 0.84 to 0.86) or IAAF score (|rho| = 0.70 to 0.77) in absolute values were slightly lower. The correlations detected between other HR-derived parameters and running performance were weaker (|r or rho| = 0.24 to 0.70). Regression models identified %HRmax at 14.5 km·h^?1 as the strongest predictor of both PTS (β = ?0.72) and IAAF score (β = ?0.72). Consequently, tests based on %HRmax may provide a non-invasive and inexpensive alternate method for predicting the performance of these athletes.  相似文献

Reliability and validity of field-based measures of leg stiffness and reactive strength index in youths     

Rhodri S. Lloyd  Jon L. Oliver  Michael G. Hughes  Craig A. Williams 《Journal of sports sciences》2013,31(14):1565-1573

Abstract

The aim of the study was to assess the reliability of a mobile contact mat in measuring a range of stretch–shortening cycle parameters in young adolescents. Additionally, vertical leg stiffness using contact mat data was validated against a criterion method using force–time data. The reliability study involved 18 youths completing a habituation and three separate test sessions, while 20 youths completed a single test session for the validity study. Participants completed three trials of a squat jump, countermovement jump, and maximal hopping test and a single trial of repeated sub-maximal hopping at 2.0 Hz and 2.5 Hz. All tests were performed on the contact mat. Reliability statistics included repeated-measures analysis of variance, intraclass correlation coefficient, and coefficient of variation (CV), while the correlation coefficient (r) and typical error of estimate (TEE) were reported for the validity study. Squat jump height was the most reliable measure (CV = 8.64%), while leg stiffness during sub-maximal hopping, and reactive strength index produced moderate reliability (CV = 10.17–13.93% and 13.98% respectively). Measures of leg stiffness obtained from contact mat data during sub-maximal hopping were in agreement with the criterion measure (r = 0.92–0.95; TEE = 6.5–7.5%), but not during maximal hopping (r = 0.59; TEE = 41.9%). The contact mat was deemed a valid tool for measuring stretch–shortening cycle ability in sub-maximal but not maximal hopping. Although reliability of performance was generally moderate, the tests offer a replicable assessment method for use with paediatric populations.  相似文献   

Effects of playing surface on physiological responses and performance variables in a controlled football simulation     

Michael G. Hughes  Laurence Birdsey  Rob Meyers  Daniel Newcombe  Jon Lee Oliver  Paul M. Smith 《Journal of sports sciences》2013,31(8):878-886

Abstract

In spite of the increased acceptance of artificial turf in football, few studies have investigated if matches are altered by the type of surface used and no research has compared physiological responses to football activity on artificial and natural surfaces. In the present study, participants performed a football match simulation on high-quality artificial and natural surfaces. Neither mean heart rate (171 ± 9 beats · min^?1 vs. 171 ± 9 beats · min^?1; P > 0.05) nor blood lactate (4.8 ± 1.6 mM vs. 5.3 ± 1.8 mM; P > 0.05) differed between the artificial and natural surface, respectively. Measures of sprint, jumping and agility performance declined through the match simulation but surface type did not affect the decrease in performance. For example, the fatigue index of repeated sprints did not differ (P > 0.05) between the artificial, (6.9 ± 2.1%) and natural surface (7.4 ± 2.4%). The ability to turn after sprinting was affected by surface type but this difference was dependent on the type of turn. Although there were small differences in the ability to perform certain movements between artificial and natural surfaces, the results suggest that fatigue and physiological responses to football activity do not differ markedly between surface-type using the high-quality pitches of the present study.  相似文献   

Influence of regression model and initial intensity of an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and running performance     

Jordan Santos-Concejero  Ross Tucker  Cristina Granados  Jon Irazusta  Iraia Bidaurrazaga-Letona  Jon Zabala-Lili 《Journal of sports sciences》2013,31(9):853-859

Abstract

This 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   

The Dynamics of Leisure Motivation: The Effects of Outcome on Leisure Needs     

Seppo E. Iso-Ahola  Jon R. Allen 《Research quarterly for exercise and sport》2013,84(2):141-149

Abstract

Predicated upon the premise that leisure needs are socially determined and therefore dynamic qualities of leisure motivation, this field study investigated the effects of outcome (winning, losing, no outcome) of leisure participation on male and female subjects' leisure needs. Subjects were 438 players of 60 teams in the intramural basketball program comprised of competitive and recreational leagues. Factor analysis produced seven need factors, of which three dealt with interpersonal relationships, two with competence and two with escape or diversion. ANOVAs performed on the resultant factor scores showed that successful and unsuccessful leisure experiences strongly shaped subjects' needs for leisure participation, but these effects were often mediated by the sex of subjects and the competitive levels of leagues in which they played. Generally, winning and losing had just the opposite effects on males' and females' needs; winning increased females' and decreased males' needs. The effects of competitiveness of league types suggested that competitive and recreational leagues serve different psychological functions for males and females because the two leagues are expected to fulfill different leisure needs.  相似文献
