Testing a model of teaching for anxiety and success for English language teaching     

Evrim Önem  İclal Ergenç 《Cambridge Journal of Education》2013,43(3):357-376

Much research has shown that there is a negative relationship between high levels of anxiety and success for English language teaching. This paper aimed to test a model of teaching for anxiety and success in English language teaching to affect anxiety and success levels at the same time in a control-experiment group with pre- and post-test study design. Anxiety levels were measured by anxiety questionnaires and electroencephalograph recordings of brain waves and success was measured by grammar tests prepared by the researcher. Results of Mann–Whitney U Test, Wilcoxon Signed Ranks Test and ANOVA pointed to a statistically significant difference in anxiety and success levels between the experiment and control group. Discussion of the results as well as implications for future research is presented.  相似文献   

Evaluation of retirement planning programs: A qualitative analysis of methodologies and efficacy     

Cristineide Leandro-França  Sheila Giardini Murta  Douglas A. Hershey  Leonardo Barbosa Martins 《Educational gerontology》2013,39(7):497-512

ABSTRACT

The objective of this integrative literature review was to evaluate the quality of retirement planning programs described in the extant literature. This was accomplished through a qualitative analysis of methodological and efficacy criteria as described by Flay et al. (2005), Kazdin (2010, 2011 and Murta (2005). Several databases were consulted in searching for retirement program articles including: Academic Search Premier, Medline, PsycInfo, and Web of Science, among others. Retirement planning intervention articles published in English, Portuguese, and Spanish were considered, with a focus on their evaluation methods and results. Eleven studies were identified that described the procedures for both program implementation and intervention evaluation. Results revealed methodological shortcomings in the papers reviewed, with concerns being related to a lack of experimental or quasiexperimental approaches, a failure to use previously validated measurement instruments and longitudinal assessments, and insufficiently robust data analysis procedures. That said, however, there was evidence from multiple investigations that the intervention programs examined led to increases in knowledge, positive changes in attitudes linked to retirement, and an increase in retirement-linked planning and preparation behaviors. Identification of strengths and weaknesses in the methods used and efficacy of these interventions could facilitate the construction of a research agenda aimed at promoting more favorable research designs. Use of more rigorous designs would stand to improve the internal validity of these retirement programs and, consequently, progress in this field.  相似文献

Physiological responses in different intensities of resistance exercise – Critical load and the effects of aging process     

Vivian Maria Arakelian  Cássia da Luz Goulart  Renata Gonçalves Mendes  Nuno Manoel de Sousa  Renata Trimer  Solange Guizilini 《Journal of sports sciences》2019,37(12):1420-1428

Aim was to identify critical load (CL) in young and elderly apparently healthy male cohorts. To contrast the metabolic, cardiovascular and perceptual responses on CL according to age. We evaluated 12 young (23 ± 3 years) and 10 elderly (70 ± 2 years) apparently healthy active males, who underwent: (1) 1 repetition maximum (1RM) test on a 45° Leg Press; (2) on different days, three high-intensity resistance exercise constant load tests (60%, 75% and 90% 1RM) until fatigue (Tlim). Absolute values of both the CL asymptote and curvature constant (kg) were significantly lower in elderly subjects (P < 0.05). In contrast, elderly subjects demonstrated a significantly higher number of repetitions at CL when compared with young subjects (P < 0.05). As expected, oxygen uptake (VO₂) and heart rate (HR) during maximal aerobic exercise testing were significantly reduced in older subjects. However, percent-predicted aerobic capacity were higher in older subjects (P < 0.05). In addition, blood lactate ([La^?]) corrected to Tlim and rating of perceived exertion values were greater in younger subjects at all intensities (P < 0.05). These findings, despite reduced force production in older subjects, endurance-related parameters are well preserved according to age-adjusted percent-predicted values in apparently healthy males.  相似文献   

Determination of peak cardiorespiratory fitness parameters in children: which averaging method should we use?     

Joel Blanchard  Samuel Blais  Philippe Chetaille  Michele Bisson  François P. Counil  Thelma H. Girard 《Journal of sports sciences》2019,37(11):1265-1269

The purpose of this study was to identify which averaging methods most accurately measures peak cardiorespiratory fitness (CRF) parameters [peak O₂ uptake (VO₂), peak O₂pulse and peak respiratory exchange ratio (RER)] in a sample of healthy children and adolescents. In this cross-sectional multicenter study, we recruited 278 healthy children aged 12–17 years. We compared the mean peak value of three CRF parameters using the recommended averaging methods (30-second block average) with alternative averaging methods such as moving averages or shorter smoothing periods. We also assessed averaging methods for accuracy by individually reviewing breath-by-breath scatter plots. The 30-second block average method resulted in a lower mean peak VO₂ and in an increased proportion of underestimated peak values. Using a 30-second moving average significantly increased mean peak values which increased accuracy. Similar results were found for peak RER and peak O₂pulse. In conclusion, the currently recommended averaging method (30-second block average) increased the risk of misinterpretation of peak CRF values in children. Using a moving average approach decreased misinterpretation and increased accuracy.  相似文献   

How should cultural diversity be measured? An application using the French publishing industry     

Françoise Benhamou  Stéphanie Peltier 《Journal of Cultural Economics》2007,31(2):85-107

Despite the lack of a clear definition of the concept, “cultural diversity” has remained a core issue for more than a decade (WTO, UNESCO, etc.). The aim of this paper is to begin to fill this gap. We argue that cultural diversity is a multi-dimensional concept and that accurate metrics must rely on three criteria: variety, balance and disparity. We also stress that supplied and consumed diversity have to be distinguished. We apply this set of multiple measures of diversity to publishing data for France over the period 1990–2003. Our main result is that the situation of the publishing industry in terms of cultural diversity is highly dependent on the dimension considered. Hence, diversity increases when variety is the sole consideration, whereas taking balance or disparity into account leads to the opposite conclusion. This issue raises a series of questions about the use of diversity measures in a policy debate concerned with furthering cultural diversity.

Effect of different recovery patterns on repeated-sprint ability and neuromuscular responses   总被引：1，自引：0，他引：1  

Billaut F  Basset FA 《Journal of sports sciences》2007,25(8):905-913

We examined the effect of recovery pattern on mechanical and neuromuscular responses in active men during three repeated-sprint ability tests consisting of ten 6-s cycling sprints. Within each test, the recovery duration was manipulated: constant, increasing, and decreasing recovery pattern. Maximal voluntary contractions of the knee extensors were performed before and after the repeated-sprint ability tests to assess strength and electromyographic activity [root mean square (RMS)] of the quadriceps muscle. We observed different fatigue patterns for peak and mean power output between recovery patterns, with earlier decrements recorded during the increasing recovery pattern. Total work performed over the ten sprints was also lower in the increasing recovery pattern (43.8 +/- 5.4 kJ; P < 0.05). However, the decreasing recovery pattern induced a greater overall power output decrement across the sprints (-15.8%; P < 0.05), compared with the increasing recovery pattern (-5.1%) but not the constant recovery pattern (-10.1%). The decreasing recovery pattern was also associated with higher post-sprint RMS values (+16.2%; P < 0.05). Therefore, the recovery pattern within successive short sprints may influence repeated-sprint ability, and may lead to greater post-sprint neuromuscular adjustments when recovery intervals decrease between sprints. We conclude that peripheral impairments caused the major differences in repeated-sprint ability between recovery patterns.  相似文献   

Do achievement goals mediate stereotype threat?: an investigation on females' soccer performance     

Chalabaev A  Sarrazinr P  Stone J  Cury F 《运动与训练心理学杂志》2008,30(2):143-158

This research investigated stereotype threat effects on women's performance in sports and examined the mediation of this effect by achievement goals. The influence of two stereotypes-relative to the poor athletic ability and the poor technical soccer ability of women-were studied. Fifty-one female soccer players were randomly assigned to one of three conditions, introducing the task as diagnostic of athletic ability, technical soccer ability, or sports psychology. Next, they filled out a questionnaire measuring achievement goals and performed a soccer dribbling task. Results showed that compared with the control condition, females' performance significantly decreased in the athletic ability condition and tended to decrease in the technical soccer ability condition. Moreover, participants endorsed a performance-avoidance (relative to performance-approach) goal when the stereotypes were activated. However, this goal endorsement was not related to performance. The implications of these results for understanding the role of stereotypes in gender inequalities in sports are discussed.  相似文献
