Lower limb amputees often experience complications with the use of conventional socket-type prostheses, which further reduce their already compromised ability to perform the activities of daily living, or to participate in sporting activities. During the last two decades, a new technology of direct skeletal attachment (osseointegration) of prosthesis to the femoral residuum has been developed. The aim of this research was to assess the implant design, surgery protocols, and functional testing of this new technology on the first 100 patients using the Integral Leg Prosthesis procedure. This new knowledge can guide future engineering developments of osseointegration within the sporting arena. Between 1999 and 2013, direct skeletal implantation was performed on 112 amputees, from two centres in Germany and Australia. From the experience of the surgical team, modifications were made to the implant design. This re-engineering of the implant has reduced the surgical revisions due to infection from 29 % with the early implant design down to 7 %. The functional testing of the 34 Australian cases were assessed pre- and 12 months post-implant with significant improvements of one complete K-scale; the Q-TFA measures increased (50.9–86.7), whilst the Timed Up and Go decreased significantly (12.43 s ± 3.89 to 8.03 s ± 2.80), and the 6 min walk increased (304.0–383.9 m). From these findings, osseointegration technology is realistically the way of the future for amputee athletes. Further refinement of the implant design and sports-specific functional testing are required to define the potential of this technology.  相似文献   

The Teacher Behavior Inventory: validation of teacher behavior in an interactive lecture environment     

Siti Nurma Hanim Hadie  Asma’ Hassan  Saiful Bahri Talip  Muhamad Saiful Bahri Yusoff 《Teacher Development》2019,23(1):36-49

Students’ rating of teacher behaviors provides valuable information on teaching improvement and instructional quality. Unfortunately, there is a lack of new validated instruments for measuring teacher behaviors. The Teacher Behaviors Inventory is an old inventory that was initially developed to measure teaching behaviors as regards lecture-based instructions, which is effected through the use of low-inference items. The aim of this study was to assess its continued suitability in the present educational setting by examining its construct validity and internal consistency through the lens of one lecturer’s teaching behaviors, as rated by 527 students after six interactive lectures. The variables evaluated, as mentioned above, were achieved after an items removal process, which resulted in a 32-item version. Apart from being valid and reliable, this condensed version allows for immediate assessment of teaching behaviors after an instruction session as the rating procedure is now more straightforward and less time-consuming, and also enables a reduction in rating errors. Therefore, the 32-item format serves as a practical diagnostic feedback tool in the present educational arena, permitting a longitudinal teaching behavior assessment to enhance teachers’ professional development.  相似文献   

Reporting Quality of Single-Case Research Published in Learning Disabilities Journals     

Brittany L. Hott  Sarah Heiniger  Jasmine Justus  Kathleen M. Randolph  Amal Al Shabibi  Brooki Beasley  Kerry Frank  Wendy Mitchell  Courtney Tennell  Fanee Wester 《Learning disabilities research & practice》2023,38(3):224-238

Single-case research designs are useful for learning disability researchers interested in refining novel interventions (e.g., new mathematics intervention) before scaling, small n populations (e.g., students with comorbid learning and emotional and behavioral disabilities), and testing unique conditions (e.g., remote locales). Much attention has been devoted to developing research quality standards, which is essential for replication and implementation fidelity; however, little is known about the reporting quality of single-case design studies. To gain insight into the quality of learning disability single-case research design study reporting, we analyzed 72 articles published between 2010 and 2021 in six learning disability-focused journals using the Single-Case Reporting Guideline In BEhavioral interventions (SCRIBE) standards. Findings suggest that reporting quality has remained stagnant, and none of the studies reviewed met all of the reporting standards. Alignment with standards ranged from 33% to 77%. Implications for researchers and practitioners are discussed.  相似文献   

Relationships between anthropometric measures and athletic performance,with special reference to repeated-sprint ability,in the Qatar national soccer team

Abstract

The aim of this study was to determine potential relationships between anthropometric parameters and athletic performance with special consideration to repeated-sprint ability (RSA). Sixteen players of the senior male Qatar national soccer team performed a series of anthropometric and physical tests including countermovement jumps without (CMJ) and with free arms (CMJwA), straight-line 20 m sprint, RSA (6 × 35 m with 10 s recovery) and incremental field test. Significant (P < 0.05) relationships occurred between muscle-to-bone ratio and both CMJs height (r ranging from 0.56 to 0.69) as well as with all RSA-related variables (r < –0.53 for sprinting times and r = 0.54 for maximal sprinting speed) with the exception of the sprint decrement score (S_dec). The sum of six skinfolds and adipose mass index were largely correlated with S_dec (r = 0.68, P < 0.01 and r = 0.55, P < 0.05, respectively) but not with total time (TT, r = 0.44 and 0.33, P > 0.05, respectively) or any standard athletic tests. Multiple regression analyses indicated that muscular cross-sectional area for mid-thigh, adipose index, straight-line 20 m time, maximal sprinting speed and CMJwA are the strongest predictors of S_dec (r² = 0.89) and TT (r² = 0.95) during our RSA test. In the Qatar national soccer team, players’ power-related qualities and RSA are associated with a high muscular profile and a low adiposity. This supports the relevance of explosive power for the soccer players and the larger importance of neuromuscular qualities determining the RSA.  相似文献   

Omani girls’ conceptions of gender equality: addressing socially constructed sexist attitudes through educational intervention     

Fatma H. Al Sadi 《牛津教育评论》2017,43(2):209-224

This paper is based on a quasi-experimental study which examines the effects of a school-based intervention on Omani girls’ attitudes towards the notion of gender equality. A questionnaire was administered before and after the intervention to 241 girls (116 in the experimental group; 125 in the control group). A semi-structured interview was conducted before and after the intervention with 16 participants (eight from the experimental group; eight from the control group). Analysis of quantitative data in the post-intervention round revealed statistically significant differences between the two groups in attitudes towards gender equality in favour of the experimental group. Similarly, the analysis of qualitative data from the post-intervention round showed that the experimental group differed significantly from the control group in its attitudes towards women’s roles and gender equality. The paper concludes by emphasising the critical role that education can play in challenging and transforming prejudicial and discriminatory attitudes.  相似文献   

Predicting First Grade Reading Performance from Kindergarten Response to Tier 1 Instruction     

Al Otaiba S  Folsom JS  Schatschneider C  Wanzek J  Greulich L  Meadows J  Li Z  Connor CM 《Exceptional children》2011,77(4):453-470

Many schools are beginning to implement multi-tier response to intervention (RTI) models for the prevention of reading difficulties and to assist in the identification of students with learning disabilities (LD). The present study was part of our larger ongoing longitudinal RTI investigation within the Florida Learning Disabilities Center grant. This study used a longitudinal correlational design, conducted in 7 ethnically and socio-economically diverse schools. We observed reading instruction in 20 classrooms, examined response rates to kindergarten Tier 1 instruction, and predicted students' first grade reading performance based upon kindergarten growth and end of year reading performance (n = 203). Teachers followed an explicit core reading program and overall, classroom instruction was rated as effective. Results indicate that controlling for students' end of kindergarten reading, their growth across kindergarten on a variety of language and literacy measures suppressed predictions of first grade performance. Specifically, the steeper the students' trajectory to a satisfactory outcome, the less likely they were to demonstrate good performance in first grade. Implications for future research and RTI implementation are discussed.  相似文献

Comparison of heart rate monitoring with indirect calorimetry for energy expenditure evaluation     

Zhusheng Yu  Eszter Völgyi  Ru Wang  Andrea Ember  Petri Wiklund  Markku Alén  Frances A. Tylavsky  Sulin Cheng 《运动与健康科学(英文)》2012,1(3):178-183

PurposeThe purpose of this study was to compare established methods with newly-developed methods for estimating the total energy expenditure (TEE).MethodsThe study subjects comprised 46 individuals, including 16 middle-aged men (mean age 51.4 years), 14 middle-aged women (mean age 49.9 years) and 16 young women (mean age 19.1 years). The TEE was estimated from 24-h heart rate (HR) data using newly-developed software (MoveSense HRAnalyzer 2011a, RC1, Suunto Oy, Vantaa, Finland), and was compared against the TEE determined using doubly labeled water (DLW). Agreement between the two methods was analyzed using Bland and Altman plots.ResultsThe HR method yielded similar TEE values as the DLW method at the group level, with an average of 8.6 kcal/day in the difference in the mean, but with large individual variations. Forty-four (96%) out of 46 subjects fell within ±2SD of the mean difference in TEE comparisons, and there was no tendency towards under- or over-estimation.ConclusionOur results indicate that the current software using HR analysis for the estimation of daily TEE needs further development for use with free-living individuals.  相似文献   

STAFF DEVELOPMENT GOALS AND PRACTICES IN U.S. COMMUNITY COLLEGES     

Al Smith 《Community College Journal of Research & Practice》2013,37(3):209-225

The staff development goals and activities of United States community colleges were studied. A total of 1,315 questionnaires were mailed to community college academic deans in the spring of 1979. Of the 687 colleges responding, 413 indicated that their college had an organized staff development program or set of activities, and another 241 colleges indicated no such program at this time.

The results showed that the most frequently mentioned staff development goals of the 31 goals studied related to the improvement of the full‐time teaching faculty as opposed to part‐time faculty and other academic and non‐academic support personnel. Second, the most highly rated and used practices were travel and grants programs for faculty. Some of the least effective of 48 practices investigated were programs for the “faculty evaluation of college administrators” and “lighter than normal teaching loads for first‐year faculty.”

It is recommended that colleges offer a variety of staff development programs for each of their staff development groups and that research be conducted to determine participant perceptions of the usefulness of various staff development practices.  相似文献
