The use of statistical investigations as a teaching strategy have been shown to both motivate and engage students. The implementation of a statistical investigation to measure intelligence is described, covering core statistical principles and key elements of research design. 相似文献

The aims of the study were to modify the training impulse (TRIMP) method of quantifying training load for use with intermittent team sports, and to examine the relationship between this modified TRIMP (TRIMP(MOD)) and changes in the physiological profile of team sport players during a competitive season. Eight male field hockey players, participating in the English Premier Division, took part in the study (mean+/-s: age 26+/-4 years, body mass 80.8+/-5.2 kg, stature 1.82+/-0.04 m). Participants performed three treadmill exercise tests at the start of the competitive season and mid-season: a submaximal test to establish the treadmill speed at a blood lactate concentration of 4 mmol . l(-1); a maximal incremental test to determine maximal oxygen uptake ([V]O(2max)) and peak running speed; and an all-out constant-load test to determine time to exhaustion. Heart rate was recorded during all training sessions and match-play, from which TRIMP(MOD) was calculated. Mean weekly TRIMP(MOD) was correlated with the change in [V]O(2max) and treadmill speed at a blood lactate concentration of 4 mmol x l(-1) from the start of to mid-season (P<0.05). The results suggest that TRIMP(MOD) is a means of quantifying training load in team sports and can be used to prescribe training for the maintenance or improvement of aerobic fitness during the competitive season. 相似文献

We examined the hypothesis that congruence between motivational dominance and state results in optimal psychological responses and performance during exercise. Twenty participants (10 telic dominant and 10 paratelic dominant) rated their stress at 5 min intervals as they cycled on an ergometer at gas exchange threshold for 30 min in both telic and paratelic state manipulated conditions. Participants then performed a test to exhaustion at a resistance equivalent to 110% of VO(2max). The hypothesized interaction between condition and dominance was significant for internal tension stress, as paratelic dominants were more stressed than telic dominants when exercising in the telic state and telic dominants were more stressed than paratelic dominants when exercising in the paratelic state. Similarly, the condition × dominance interaction for internal stress discrepancy was significant, as paratelic dominants reported greater internal stress discrepancy exercising in the telic compared with the paratelic state. Findings are discussed in relation to the application of reversal theory for understanding stress responses during aerobic exercise. 相似文献

This article briefly outlines the history of IMTEC, from its origins within the OECD in Paris to its present independent state as a Norwegian non‐profit‐making foundation. Three aspects of its work are identified: Research and Development, Networking Activity, and Consultancy (Technical Assistance). Detailed information about each of these is given. The authors who write on their own behalf, conclude by anticipating a period of interesting expansion for the organisation. 相似文献

Behavioral Organization in Newborns and Its Relation to Adrenocortical and Cardiac Activity 总被引：4，自引：0，他引：4
Spangler, Gottfried, and Scheubeck, Roswitha. Behavioral Organization in Newborns and Its Relation to Adrenocortical and Cardiac Activity. Child Development, 1993, 64 , 622–633. The aim of this study was to assess relations between behavioral organization and adrenocortical and cardiac activity in newborns. Twice during the neonatal period, the behavioral organization of 42 newborns, in terms of orientation and irritability, was assessed by the Neonatal Behavioral Assessment Scale (NBAS), and the newborns' cortisol response to the NBAS procedure was determined. In addition, cardiac activity was assessed during 1 of the NBAS. Whereas there were only inconsistent correlations between newborn irritability and the adrenocortical response during NBAS, low orientation was associated with a higher increase in cortisol in both of the assessments. In addition, orientation was predicted by basal cortisol level. High heart rates were associated with high irritability and low regulation of state, and, in addition, negative relations were indicated between orientation and heart rate variability. The findings support a coping model of biobehavioral relations in newborns. 相似文献

Research and development (R&D) investment activity plays a crucial role in developing high-tech industries. In recent decades, China has made sustained investments in its domestic high-tech industries, with the goal of increasing their productivity. This paper investigates the effect of this investment on relative R&D efficiency across China's high-tech sectors. Data Envelopment Analysis (DEA) was used to generate quantitative indices for sector comparisons. The analysis of this study indicates that overall R&D investment efficiency did not increase from 1998 to 2009, despite R&D expenditure increasing by 2188%. Over the same period, most sectors suffered from decreasing returns to scale (DRS), presumably also reflecting the inefficient R&D investment. Most of the sectors showed significant fluctuation on R&D investment efficiency. This research result indicates that the problem of China's high-tech industry may be from the inefficiency of its technology commercialization processes, and therefore represents a critical parameter for policy makers and managers. 相似文献

This introductory essay discusses the origins of current interest in performances and performativity in the history of science as an outcome of the concern with understanding science as practice that emerged from the 1980s onward. The language of performance, it suggests, provides useful analytic tools for historians of science because it focuses our attention on the bodies of practitioners, their embodied practices, and their presentation of self to different audiences. It provides a new approach to understanding the politics of knowledge production and dissemination. Lastly, the essay suggests, the emphasis on performance invites us to develop new, nontextual strategies for representing our own researches. 相似文献
