Collaborative Group Interactions of Students from Two Ethnic Backgrounds     

Sue Wright  Denis Lander 《高等教育研究与发展》2003,22(3):237-251

Australian university campuses are reflecting increased cultural diversity at a time when group work is emphasised as an effective student-centred approach to learning. This paper reports an investigation of differences in rates of verbal interaction by 72 first year male undergraduate engineering students from two ethnic cohorts (Australian-born Anglo-European and overseas-born South East Asian students) during a collaborative group activity. A quantitative methodology was employed. Verbal interactions were recorded under two conditions: mono-ethnic groups containing four students from one ethnic cohort; and bi-ethnic groups made up of two students from each ethnic cohort. Analysis of Variance (ANOVA) revealed highly significant differences for the main effects of both Ethnicity and Group Type and also their Interaction. The key finding of this study suggests that the South East Asian students were inhibited in terms of their verbal participation when with Australian students.  相似文献

Educational funding and management under constraint with special reference to higher education in Australia     

Denis Davis 《Higher Education》1987,16(1):63-73

This paper shows how education is in competition with other areas of government spending, inside and outside the social welfare expenditure area, for funding, and shows how its advocates must increasingly legitimise their claims. The paper argues, by particular reference to the case of higher education in Australia, that education decision-makers argue and legitimise their claims on an external and internal dimension: the external, to get as much funding to the programs as possible, the internal, to ensure that the output of the programs is as mutually compatible as possible between the desires of those producing them and those funding them.  相似文献   

Rap as a Social and Political Revealer: Diam's and Changes in French Value Systems     

Denis‐Constant Martin 《Culture, Theory & Critique》2013,54(3):257-273

Abstract

In 2006, a young female rapper named Diam's released an album that became the best‐selling CD in France: her CD and its reception is treated as a social phenomenon and examined against the backdrop of political arguments which developed in France in 2006–2007. Musical analysis shows that the sonic backgrounds of Diam's rap illustrated the importance of combinations and hard work in the symbolical production of a new order. Her texts manifested new combinations of social values which brought into the public debate changes in value systems that were just becoming developed enough to be taken up by political organisations and leaders. This is why the main themes in Diam's CD converged with topics engaged by the two main candidates in the French 2007 presidential election. This paper, combining the resources of musicology, literary analysis and political sociology analyses how Diam's put in aesthetic and emotional forms combinations of values that had been brewing underground for the past 30 years. It invites a reconsideration of the interpretation of rap as an expression of rebellion, or even as an element of counter‐culture, and apprehends it as a ‘social revealer’ that brings new values and representations into public debate and stimulates discussion around them. Diam's album was an ‘unidentified political object’ that shed original light on the way politics and politician are perceived by ordinary citizens, or specific groups among them, such as the youth.  相似文献   

Evolution of fat oxidation during exercise in obese pubertal boys: Clinical implications

Abstract

In this study, we examined fat oxidation rates during exercise in obese pubescent boys. Three groups of pubescent boys (16 pre-pubescent, Tanner's stage I; 16 pubescent, Tanner's stage III; and 14 post-pubescent, Tanner's stage V) performed a graded test on a leg cycle ergometer. The first step of the test was fixed at 30 W and power was gradually increased by 20 W every 3.5 min. Oxygen consumption ([Vdot]O₂) and carbon dioxide production ([Vdot]CO₂) were determined as the means of measurements during the last 30 s of each step, which allowed us to calculate fat oxidation rates versus exercise intensity. Between 20 and 50% of peak oxygen consumption ([Vdot]O_2peak), fat oxidation rate in relative values (mg · min^?1 · kg FFM^?1) decreased continuously with pubertal development. In the same way, the maximum rate of fat oxidation occurred at a lower percentage of [Vdot]O_2peak (pre-pubescent: 49.47 ± 1.62%; pubescent: 47.43 ± 1.26%; post-pubescent: 45.00 ± 0.97%). Our results confirm that puberty is responsible for a decrease in fat free mass capacities to use fat during exercise. The results suggest that post-pubescent obese boys need to practise physical activity at a lower intensity than pre-pubescent boys to enhance lipolysis and diminish adipose tissue and the consequences of obesity.  相似文献

Predictive ability of the medicine ball chest throw and vertical jump tests for determining muscular strength and power in adolescents     

Daniel A. Hackett  Timothy B. Davies  Denis Ibel  Stephen Cobley  Ross Sanders 《Measurement in physical education and exercise science》2018,22(1):79-87

This study examined the predictive ability of the medicine ball chest throw and vertical jump for muscular strength and power in adolescents. One hundred and ninety adolescents participated in this study. Participants performed trials of the medicine ball chest throw and vertical jump, with vertical jump peak power calculated via an estimation equation. One-repetition maximum and peak power for the chest press and leg press were assessed using pneumatic exercise machines. The medicine ball chest throw strongly correlated with chest press one-repetition maximum and peak power, while the vertical jump peak power strongly correlated with leg press one-repetition maximum and peak power. The predictive ability of medicine ball chest throw was better than vertical jump peak power for muscular strength and power when controlling for sex, age, height, weight, and maturation, and was not affected by involvement in sports. Results show good predictive ability of the medicine ball chest throw for muscular strength and power in adolescents, while predictable ability of vertical jump peak power is weakened when other factors are taken into account.  相似文献   

Oxygen uptake during mini trampoline exercise in normal-weight,endurance-trained adults and in overweight-obese,inactive adults: A proof-of-concept study     

Christoph Höchsmann  Anja Rossmeissl  Sandra Baumann  Denis Infanger  Arno Schmidt-Trucksäss 《European Journal of Sport Science》2018,18(5):753-761

Objectives: To examine cardiorespiratory exertion during mini trampoline exercises of different intensities in both endurance-trained athletes and overweight-obese adults. Methods: Physically healthy participants (Group A: normal-weight, endurance-trained athletes; Group B: inactive, overweight-obese adults) participated in two measurement appointments and three training sessions in between appointments, in which participants familiarized themselves with the use of the mini trampoline and the execution of the exercises. The primary outcome was the ?O_2peak for each of the six mini trampoline exercises relative to the ?O_2peak as established during an all-out exercise test on a bike ergometer during the first measurement appointment. Secondary outcomes were average ?O₂ as well as maximum and average heart rate. Results: The six mini trampoline exercises generated ?O_2peak values between 42% and 81% in the endurance-trained athletes and between 58% and 87% in the overweight-obese participants, both in relation to the bike ergometer ?O_2peak. Average ?O₂ values ranged from 35% to 69% (endurance-trained athletes) and from 48% to 71% (overweight-obese participants), depending on exercise. Average heart rate likewise lay in a range that can be categorized as moderate-to-vigorous aerobic exercise for both groups. A moderate-to-strong correlation (0.658 to 0.875, depending on exercise) between bike ergometer ?O_2peak and mini trampoline ?O_2peak was found for all six exercises. Conclusions: Mini trampoline exercise has the potential to produce training intensities that concur with established exercise guidelines. The exercise intensity is self-adjusting and allows for an effective and safe workout for different users with a wide range of fitness levels.  相似文献
