Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for measuring in the field are needed. This work analysed the accuracy and precision of a new wireless insole forcesensor for quantifying running-related kinetic parameters. Vertical ground reaction force (GRF) was simultaneously measured with pit-mounted force plates (1?kHz) and loadsol® sensors (100?Hz) under unshod forefoot and rearfoot running-step conditions. GRF data collections were repeated four times, each separated by 30 min treadmill running, to test influence of extended use. A repeated-measures ANOVA was used to identify differences between measurement devices. Additionally, mean bias and Bland–Altman limits of agreement (LoA) were calculated. We found a significant difference (p?.05) in ground contact time, peak force, and force rate, while there was no difference in parameters impulse, time to peak, and negative force rate. There was no influence of time point of measurement. The mean bias of ground contact time, impulse, peak force, and time to peak ranged between 0.6% and 3.4%, demonstrating high accuracy of loadsol® devices for these parameters. For these same parameters, the LoA analysis showed that 95% of all measurement differences between insole and force plate measurements were less than 12%, demonstrating high precision of the sensors. However, highly dynamic behaviour of GRF, such as force rate, is not yet sufficiently resolved by the insole devices, which is likely explained by the low sampling rate. 相似文献

A diagnostic goal of the “Profile analysis according to Grießhaber” is the assessment of the grammatical ability to place verbs in German sentences in the correct syntactical position. To evaluate the test quality for the first time, 403 monolingual and multilingual primary school children were randomly assigned to three different test materials: Test material that specifically stimulated the target competence led to the best test results. This indicates a low objectivity of application. In addition, ceiling effects for primary school children were detected, which means that the profile analysis can only slightly differentiate among the grammatical abilities of the children. Retest reliability and objectivity of analysis are also too small. In summary, the test quality of the assessment tool should be improved with respect to all of the test quality criteria considered. Hence, we recommend standardizing the profile analysis better and adding more sensitive diagnostic criteria for primary school aged children. Other aspects of profile analysis, for example the improvement of diagnostic competencies of teachers, are recommended for future research. 相似文献

ABSTRACTThis paper examines the pressures experienced by teachers as they strive to embody the Teach For America (TFA) motif of ‘relentless pursuit’. It draws on interviews conducted with 36 teachers and uses a Bourdieuian analysis to consider the mechanisms of control manifested through socialization and corps member habituation. The findings suggest that corps members experience both symbolic and self-imposed overt violence as they aim to meet the demands of TFA. This has implications for the increasing number of teachers in programs around like TFA as well as the broader discourses of teacher accountability and the teaching profession. 相似文献

To date, very few studies have explored the incidence of motor impairment amongst children with social, emotional and behavioural difficulties (social, emotional and mental health (SEMH); formerly SEBD in England). Following research that suggests an increase in motor difficulties in young children and adolescents with SEMH difficulties, this study compares profiles of motor ability using the Movement ABC-2 assessment in children attending a specialist SEMH primary school with a typically developing comparison group and children with a diagnosis of developmental coordination disorder. We report an increased prevalence of borderline or clinically significant motor impairment amongst children with SEMH difficulties compared to the comparison group, with 44% of the SEMH special school sample falling within these ranges. We suggest that bearing in mind the increased likelihood for motor impairment is important in SEMH education, as it has likely impact on classroom functioning and ability and motivation to take part in socially and academically relevant activities. 相似文献

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

In this first Danish study of adult reading skills, 1124 adults between 18 and 67 years of age participated in an interview
about reading habits and skills, and 445 were tested individually at home using six common texts. Great care was taken to
ascertain that subjects were representative of the whole adult population and that the texts covered most types of everyday
reading. Three percent of the participants were found to have severe functional reading difficulties and a further 9 percent
to have moderate difficulties. Regression analyses found several unique predictors of reading difficulties: age (adults over
45 years reading more poorly than younger adults), limited basic education, no vocational training nor higher education, and
a small amount of reading needed at work. The rate of poor readers was about four times higher among persons with low income
than among others. Men and women read equally well although men tended to rate themselves lower as readers than women did.
Methodological issues and some educational implications are discussed. 相似文献

We report an analysis of whether a psychology placement provides significant benefit to graduates’ careers. Destination of Leavers from Higher Education (DLHE) survey data six months post‐graduation suggested that placement programme graduates across the university are significantly more likely to be (1) in work and (2) in graduate‐level jobs. For psychology, the association between graduates’ placement status and employment status at the same time was not significant overall. However, when analyses were split by degree classification obtained, it was shown that amongst those graduates with 2.1 degrees reporting themselves as working, more placement vs. non‐placement programme graduates had obtained graduate‐level jobs (63% vs. 33%). In 2.2 classified graduates there was no significant association. This pattern persisted in the data from a survey of psychology alumni (from 18 months to six and a half years post‐graduation). Psychology placement programme alumni were also more satisfied with their careers. Although placement graduates earned marginally more, this difference did not reach statistical significance. This study was therefore able to show some measurable and persistent effects of a psychology placement year, although whether the benefits can be claimed to outweigh the costs is inconclusive. Limitations and implications of the study are discussed. 相似文献

The aim of the current study was to assess the validity of the sex-plus versus sex-only categorization method for distinguishing between different types of adolescent sex offenders (ASOs; Butler & Seto, 2002). It is hypothesized that this categorization method has utility when attempting to distinguish between generalist and specialist ASOs (Seto & Pullman, 2014). Additionally, further classification of ASOs was attempted using a well known juvenile delinquency classification scheme, early-onset versus late-onset offenders (Moffitt, 1993). The current study was an archival analysis of clinical files from a sample of 158 male ASOs seen for clinical assessment at a Metropolitan Family Court Clinic. Results indicate that sex-plus offenders are more antisocial, exhibit more psychiatric issues, and have greater deficits in general social skills compared to sex-only offenders. Conversely, sex-only offenders were found to have more atypical sexual interests, and were more likely to have greater deficits in romantic relationships compared to sex-plus offenders. Due to a power related limitation, little support was found for the use of the early-onset versus late-onset classification scheme with ASOs. Overall, these results provide further support to the validity of a sex-only versus sex-plus distinction. Given these results mirror those found in the generalist/specialist literature regarding the etiology of ASOs, sex-only and sex-plus offenders may indeed have different etiological pathways: sex-plus offenders are more driven by general antisociality factors, as the generalist perspective suggests, and sex-only offenders are more driven by special factors, as the specialist explanations suggest. 相似文献

Abstract This study examines convergence as both a concept and a process. It examines the current state of convergence, various definitions of convergence, convergence practices, and it identifies Seven Observations of Convergence to be used as a strategy for best practices for organizations to integrate new and old media. Everett Rogers (1995) diffusion of innovations and the five stages of the innovation process in organizations, coupled with innovation management research are theoretical foundations used to examine the infusion of technological changes into business practices in the media industry. The study is based on research conducted during the summer of 2002 that included in‐depth interviews, participation‐observation, and archival documents from three leading corporate media groups and convergence pioneers‐Tribune Company, Media‐General, and Belo Corp at their integrated business units in Chicago, Dallas, and Tampa, Florida. The three organizations were selected for field study because they are convergence pioneers that fell under the grandfather clause of the U.S. Federal Communications Commission 1975 cross‐ownership rule and were allowed to maintain ownership of their television broadcast and newspaper business units in the same market. 相似文献
