Measurement of ground reaction force (GRF) in running provides a direct indication of the loads to which the body is subjected
at each foot-ground contact, and can provide an objective explanation for performance outcomes. Traditionally, the collection
of three orthogonal component GRF data in running requires an athlete to complete a series of return loops along a laboratory
based runway, within which a force platform is embedded, in order to collect data from a discrete footfall. The major disadvantages
associated with this GRF data collection methodology include the inability to assess multiple consecutive foot contacts and
the fact that measurements are typically confined to the laboratory. The objective of this research was to investigate the
potential for wearable instrumentation to be employed, in conjunction with artificial neural network (ANN) and multiple linear
regression (MLR) models, for the estimation of GRF in middle distance running. A modular wearable data acquisition system
was developed to acquire in-shoe force (ISF) data. Matched data sets from wearable instrumentation (source data) and force
plate (target data) records were collected from elite middle-distance runners under controlled laboratory conditions for the
purposes of ANN and MLR model development (MD) and model validation (MV).
In terms of statistical measures of prediction accuracy the MLR model was found to provide a superior level of accuracy for
the prediction of the vertical and medio-lateral components of GRF and alternatively, the ANN model provided the most accurate
predictions of the anterior-posterior component of GRF. The prediction accuracy of each component of GRF was found to be governed
by the inherent signal variability, in which case the vertical and anterior-posterior components were more reliable and subsequently
predicted significantly more accurately than the medio-lateral component.
The emerging capability for obtaining continuous GRF records from wearable instrumentation has the potential to permit unprecedented
quantification of training stress and competition demands in running. 相似文献

Legislative activity and controversy concerning the issue ofhomosexual rights and practices has intensified in Britain overthe last decade. Despite this increase in intensity, however,the question of mass public opinion in relation to homosexualrights and practices has received little empirical investigation.In an effort to remedy this situation, this paper focuses onthe influence of party identification in determining publicattitudes towards homosexuals. Using data from the British SocialAttitudes Surveys, the results suggest that although party identificationexerts an independent and statistically significant effect onattitudes towards homosexuals, in all cases, however, theseeffects are both secondary and variable. Other equally, if notmore salient, determinants include: gender, education, age,occupation, and type of homosexual relationship. Of these varioussociodemographic variables, both age and education standout as having the strongest and most consistent effect. In otherwords, at least as far as current British society is concerned,anti-homosexual views are most prevalent among both older individualsas well as the lesser educated. 相似文献

Supported reflective practice: a programme of peer observation and feedback for academic teaching development 总被引:3,自引:0,他引:3
Maureen Bell 《International Journal for Academic Development》2013,18(1):29-39
The outcomes of the evaluation of a structured, peer-supported teaching development programme for academic staff are reported. Supported reflective practice forms the conceptual framework for the programme, which includes feedback on observed teaching and feedback on reflection. Key themes identified are the effectiveness of the supported reflective practice process, improvements to teaching practice, developing confidence and congruent espoused theory and theory-in-use, ongoing professional development and developing collegiality. Factors that facilitate the programme are explored, including the support triangle, the role of the educational developer in providing feedback and monitoring, and the role of the support colleague. Suggestions for implementation of similar programmes are offered. 相似文献

ABSTRACTThis paper assesses the reliability and validity of the teacher-completed Pupil Behaviour Questionnaire (PBQ), by comparing it to the already extensively validated teacher-completed Strengths and Difficulties Questionnaire (SDQ). Participants included 2074 primary school children participating in a universal school-based trial and 41 vulnerable children who were taking part in a study exploring the impact of exclusion from school. Exploratory factor analysis results (first factor accounts for 80.8% of the variation in the items) and the high Cronbach’s alpha value of 0.85 indicate that the PBQ consists of one substantive factor/dimension. Strong correlations between the total PBQ score and the conduct sub-scale (Spearman’s correlation coefficient (rs) = 0.67) and total difficulties score (rs = 0.59) of the SDQ indicate convergent validity. This study suggests that the PBQ is a reliable measure, and provides some evidence of validity. Further work is needed to test the PBQ in an older, more diverse populations and to measure sensitivity to change. 相似文献

According to the Lexical Restructuring Model (Metsala & Walley, 1998), children move from holistic representations of words, to syllabic representations, and finally to phonemic representations through a restructuring process driven by their developing lexical base. In contrast, the psycholinguistic grain size theory put forth by Ziegler and Goswami (2005) suggests that the awareness of individual phonemes is not possible without direct literacy instruction. The purpose of this study was to examine whether semantic knowledge and/or knowledge of grapheme/phoneme correspondences influenced the acquisition of word-blending skills by a sample of children with a reading disability. Participants were 211 second-grade and third-grade students from public elementary schools who were assigned to a reading intervention. Hierarchical Linear Modeling techniques were used to model individual growth curves of word-blending skills. Overall, findings support the psycholinguistic grain size theory of reading and suggest that instruction in the relationship between orthographic patterns and their corresponding sounds is necessary for the development of phonological awareness. 相似文献

Abstract This article addresses questions raised in the past decade regarding the role of child development knowledge for teaching and teacher preparation. Missing from the dialogue on this issue have been the voices of the students enrolled in teacher preparation programs. Accordingly, 77 preservice teachers were surveyed at the conclusion of a child development theory course. The results were examined for themes regarding how preservice teachers come to understand the changing nature of child development, the strengths and limitations of generalized theories of development, and the applicability of child development theory to their future practice. 相似文献
