Evaluating the perception of disability and the inclusive education of teachers: the Italian validation of the Sacie-R (Sentiments,Attitudes, and Concerns about Inclusive Education – Revised Scale)     

Anna Maria Murdaca  Sebastiano Costa 《欧洲特需教育杂志》2018,33(1):148-156

This study aimed to verify the factorial structure, internal validity, reliability, and criterion validity of The Sentiments, Attitudes and Concerns about Inclusive Education Revised Scale (SACIE-R) in an Italian sample. The SACIE-R is a useful tool to measure three aspects of teachers’ perceptions about inclusion, which are Sentiments, Attitudes and Concerns, providing valuable information to address the needs of teachers working with special students. A measure of this construct is currently not available in Italian, and a validation process is required. In order to provide an initial psychometric evaluation of the Italian adaptation, the SACIE-R was translated for use in Italian-speaking populations. Four hundred Italian teachers enrolled in educational teaching courses completed the SACIE-R. Confirmatory factor analyses demonstrated a good fit to the hypothesised 3-factor model, and adequate internal consistency for the scale was evidenced. A confirmatory factor analysis showed the same factor structural validity as the original instrument (although some items in the original version were deleted). Furthermore, taken together, the results showed a good level of reliability, and convergent and discriminant validity. Finally, the Italian version of the SACIE-R has good psychometric characteristics that can make it a useful measure of teacher attitude toward inclusion in the Italian educational context.  相似文献   

Contribution of limbs’ actions to the four competitive swimming strokes: a nonlinear approach     

Raul F. Bartolomeu  Mário J. Costa  Tiago M. Barbosa 《Journal of sports sciences》2018,36(16):1836-1845

The aim of our study was to assess the effect of the limbs’ actions on the nonlinear properties of the four competitive swimming strokes. Forty-nine swimmers performed all-out sprints at front-crawl, backstroke, breaststroke and butterfly, each one at full stroke (FS), only the arms’ stroke (AS), and only leg kicking (LK), in a total of 12 bouts, 6 per day. A speedo-meter cable was attached to the swimmer’s hip, to collect the speed-time raw data (f = 50Hz). Velocity, speed fluctuation, sample entropy and fractal dimension were derived from the speed-time series. Significant and moderate-strong effects were noted for both stroke and condition in all variables in the study (p ≤ 0.001; 0,560<η² < 0,952). The four competitive strokes and their three conditions exhibited nonlinear properties. The swimming pattern was less complex and more predictable for LK in comparison to AS and FS. Breaststroke and butterfly have more complex but more predictable patterns than backstroke and front-crawl.  相似文献   

Change-of direction deficit in elite young soccer players

Change-of-direction (COD) ability is an essential physical component for soccer. This study examined the relationships between conventional speed–power assessments and COD performance in elite young soccer players. Twenty-five under-20 male players from the same club (age: 17.6?±?0.8 years, height: 178.1?±?6.7?cm, body mass [BM]: 72.2?±?7.9?kg) performed sprint speed tests, vertical jumps, loaded jump squats, half squats, and Zigzag COD assessments. Moreover, the COD deficit was calculated as the difference between 20-m sprint velocity and Zigzag COD test velocity. A Pearson correlation analysis was used to determine the correlations between Zigzag COD performance and COD deficit with speed and power outputs. Although no significant relationships between speed–power variables and COD ability were present, there were still strong positive correlations between traditional neuromechanical measures and COD deficit. Briefly, it seems that higher performances in speed and power tests are not necessarily related to better performances in specific COD maneuvers. Therefore, it is recommended that coaches and technical staff include specific COD drills in soccer player routines to optimize the transference from speed and power capacities to specific COD performance.  相似文献

Balance and proprioception responses to FIFA 11+ in amateur futsal players: Short and long-term effects     

Mário Lopes  Susana Lopes  Telma Patinha  Fábio Araújo  Mário Rodrigues  Rui Costa 《Journal of sports sciences》2013,31(20):2300-2308

ABSTRACT

Background: The FIFA 11+ has shown positive effects on balance and proprioception parameters in football players. As there have been very few research studies involving futsal, we examined the short and long term effects of the FIFA 11+ on static and dynamic balance, as well as proprioception in male amateur futsal players.

Methods: Seventy-one male futsal players were randomized to two groups (FIFA 11+: n = 37, age: 27.33 ± 4.33 years; Control: n = 34, age: 25.55 ± 4.65 years). Intervention lasted 10 weeks, 2 sessions per week, succeeded by a 10-week follow-up period. For balance testing, we assessed the single-legged postural sway with a force platform (static balance) and the Y balance test (dynamic balance). Proprioception was assessed with active joint position sense testing.

Results: Complete pre-post intervention and follow-up tests were available for 61 players. The FIFA 11+ group showed higher training exposure and lower body mass index and body weight. After adjustment for baseline differences, no significant differences between groups were observed in the pre-post changes for centre of pressure measures, Y-balance and proprioception parameters both at short and long-term.

Conclusions: Performing FIFA 11+ for 10 weeks did not improve static and dynamic balance as well as proprioception in amateur futsal players.  相似文献   

Effects of cigarette smoking on cardiac autonomic function during dynamic exercise     

Goncalo V. Mendonca  Fernando D. Pereira  Bo Fernhall 《Journal of sports sciences》2013,31(9):879-886

Abstract

The purpose of this study was to investigate the acute effect of cigarette smoking on cardiac autonomic function in young adult smokers during dynamic exercise. Fourteen healthy young smokers (21.4 ± 3.4 years) performed peak and submaximal exercise protocols under control and smoking conditions. Resting and submaximal beat-to-beat R-R series were recorded and spectrally decomposed using the fast Fourier transformation. Smoking resulted in a significant decrease in work time, [Vdot]O_2peak and peak O₂ pulse (P < 0.05). Heart rate increased at rest and during submaximal exercise after smoking (P < 0.05). The raw high frequency and low frequency power were significantly reduced by smoking, both at rest and during exercise (P < 0.05). The low to high frequency ratio was higher after smoking (P < 0.05). The normalised low frequency power was also significantly increased by smoking, but only at rest (P < 0.05). These data demonstrate that the tachycardic effect elicited by smoking is accompanied by acute changes in heart rate spectral components both at rest and during exercise. Therefore, the cardiac autonomic control is altered by smoking not only at rest, but also during exercise, resulting in reduced vagal modulation and increased sympathetic dominance.  相似文献   

Measurement and analysis of soil nitrogen and organic matter content using near-infrared spectroscopy techniques   总被引：2，自引：0，他引：2

Near infrared reflectance （N1R） spectroscopy is as a rapid, convenient and simple nondestructive technique useful for quantifying several soil properties. This method was used to estimate nitrogen （N） and organic matter （OM） content in a soil of Zhejiang Province, Hangzhou County. A total of 125 soil samples were taken from the field. Ninety-five samples spectra were used during the calibration and cross validation stage. Thirty samples spectra were used to predict N and OM concentration. NIR spectra of these samples were correlated using partial least square regression. The regression coefficients between measured and predicted values of N and OM was 0.92 and 0.93, and SEP （standard error of prediction） were 3.28 and 0.06, respectively, which showed that NIR method had potential to accurately predict these constituents in this soil. The results showed that NIR spectroscopy could be a good tool for precision farming application.  相似文献   

Stairway to employment? Internships in higher education     

Patrícia Silva  Betina Lopes  Marco Costa  Dina Seabra  Ana I. Melo  Elisabeth Brito  Gonçalo Paiva Dias 《Higher Education》2016,72(6):703-721

This article aims to shed light on the current debate regarding the role of internships in higher education in graduates’ employability. In specific, it analyses empirical data on a large-scale study of Portuguese first-cycle study programmes, in order to explore indicators of the professional value of internships in the employability of higher education graduates. Results demonstrate that study programmes that include internships tend to significantly enhance graduates’ employability, particularly within the universe of polytechnic and public higher education institutions. Besides the instrumental value of internships, the impact of the nature and structure of the internship on the percentage of unemployed graduates are also discussed. Mandatory internships and the inclusion of multiple, shorter internships throughout the degree are negatively associated with unemployment levels. Results indicate work-based learning can be used as a successful strategy to bridge theoretical knowledge and practice and enhance graduate employability. These findings provide important insights for the evaluation and/or the design of internship programmes in higher education.  相似文献   

Diary-based strategy assessment and its relationship to performance in a group of trainee teachers     

Raquel Gilar  María de los ngeles Martínez Ruiz  Juan Luis Castejn Costa 《Teaching and Teacher Education》2007,23(8):1334-1344

Our work is based on the study of learning strategies used by a group of trainee teachers in a real learning situation, and how this use of strategies influences the results of the learning process. We use a diary as a tool to assess the learning strategies and compare the results obtained with those using an inventory. Our findings indicate that the deliberate use of strategies (measured by diaries) has a positive effect on knowledge acquisition, with the qualitative analysis method of the verbal protocols noted in the diaries proving more valuable than the use of traditional inventories.  相似文献   

Estranged students in higher education: navigating social and economic capitals     

Cristina Costa  Yvette Taylor  Claire Goodfellow  Sidonie Ecochard 《Cambridge Journal of Education》2020,50(1):107-123

ABSTRACT

Family is widely regarded as a cornerstone of student support. When family support exist as an essential form of social capital making, rupture of family ties places students in a disadvantageous position. This paper focuses on estranged students’ accounts of their experiences of higher education, highlighting how capital dynamics shape their academic trajectories. Based on interviews with 21 estranged students, our research uncovers different dimensions of estranged students’ struggles and successes as they move through academia. This paper explores the social imagination that surrounds the university student, or ‘student experience’, as resting upon family support. The authors propose that widening participation policies and practices need to be more attuned to the realities that mark estranged students’ experiences, as they are not only impacted by the scarcity of either economic or social capital, but also by the instability of interrelated capitals that contribute to precarious and volatile experiences.  相似文献
