The aims of this study were to determine if there are significant kinematic changes in running pattern after intense interval workouts, whether duration of recovery affects running kinematics, and whether changes in running economy are related to changes in running kinematics. Seven highly trained male endurance runners (VO 2max = 72.3 +/- 3.3 ml kg -1 min -1 ; mean +/- s) performed three interval running workouts of 10 X 400 m at a speed of 5.94 +/- 0.19 m s -1 (356 +/- 11.2 m min -1 ) with a minimum of 4 days recovery between runs. Recovery of 60, 120 or 180 s between each 400 m repetition was assigned at random. Before and after each workout, running economy and several kinematic variables were measured at speeds of 3.33 and 4.47 m s -1 (200 and 268 m min -1 ). Speed was found to have a significant effect on shank angle, knee velocity and stride length (P ? 0.05). Correlations between changes pre- and post-test for VO 2 (ml kg -1 min -1 ) and several kinematic variables were not significant (P > 0.05) at both speeds. In general, duration of recovery was not found to adversely affect running economy or the kinematic variables assessed, possibly because of intra-individual adaptations to fatigue. 相似文献

Teachers are encouraged to be active professionals in their work. Consequently, the development of professional agency in student teachers is an important dimension in teacher education. This paper reports on a study where the practice of six early childhood student teachers enrolled in a Bachelor of Education (Teaching) course was analysed, using Giddens' concept of agency, and each was found to have operated with agency. However, when additional criteria pertaining to early childhood professional practice were applied by means of a triadic viewpoint only three of the student teachers were deemed to have operated with ‘professional’ agency. Factors that were perceived to have contributed to or detracted from the student teachers' capacity to operate with professional agency were identified. Arising from these factors, this paper argues for in‐depth student teacher preparation for the practicum in order to develop professional agency. 相似文献

This session highlighted trends in continuing resource collections and collection management throughout the 30-year period from 1985 through 2015. Electronic resources became available in the 1990s and grew in prevalence from the 2000s through the present, changing the make-up of library collections and also how libraries measure collections and collection usage. Two librarians and two vendors shared their perspectives on these changes in collection development, describing how library collections now contain a combination of older formats and older ways of collecting data, and new, electronic content and automated ways of collecting and disseminating data about collections. 相似文献

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions. 相似文献

Twenty five class teachers completed a "Strengths and Difficulties" assessment for 523 children aged from 7 to 11 years of age. Children self-completed a 39-item "My Life in School" questionnaire. One third of the sample were self-reported victims of bullying behaviour. Boys with poor prosocial skills, emotional problems and general difficulties with social interaction, expression of emotion and hyperactivity were at greatest risk of being bullied. There was no significant effect of age. The data support previous research findings that gender influences the prevalence of bullying but not that younger children are more vulnerable. This study provides new evidence that teachers recognise social behaviour and interactions that can significantly affect whether primary school children are bullied. 相似文献

This paper reports 3 studies comparing thereading and phonological skills of childrenwith Down syndrome (DS) and younger normallydeveloping children of similar reading level.In Study 1, the two groups did not differ insight word or nonword reading, but the childrenwith DS did marginally less well on syllablesegmentation, rhyme and phoneme detectiontasks. Group differences in syllable andphoneme awareness appeared attributable todifferences in verbal ability (BPVS, vocabularyknowledge); however, a significant impairmentin rhyme detection remained in an analysis ofsub-groups equated in vocabulary knowledge. Thedeficit in rhyme observed in DS was replicatedin Studies 2 and 3 using simplified tests ofrhyme judgement, with the majority of childrenwith DS performing at chance on the rhymemeasures. In contrast, the two groups did notdiffer in their ability to detect phonemes inany of the 3 studies and performed above chancein initial phoneme detection and alliterationjudgement tasks, although the identification offinal phonemes was at a much lower level. Correlational analyses indicated a relationshipbetween phonological skills and reading inboth groups. However, for children with DS,letter-sound knowledge did not predict readingwhereas it did for normal controls. It issuggested that children with DS do not possessfull phoneme awareness; although they canidentify initial phonemes in words, they do notunderstand phoneme invariance and may rely lesson phonological skills for reading thancontrols. 相似文献

Numerous national reports have identified the importance of significantly improving pathways that begin with Latinx students enrolling in 2-year institutions and ultimately completing baccalaureate degrees in STEM fields at 4-year institutions. Many programs using multiple interventions have been designed, implemented, and studied to achieve this goal. To synthesize what has been learned from studies of these programs, this article presents a systematic review of published studies of programs designed to support Latinx student success in 2-year institutions and successful transfer to 4-year institutions, particularly for STEM majors. A total of 49 quantitative, 9 qualitative, and 16 mixed-methods studies published as reports, articles, or dissertations since 1980 were identified that met the criteria for the review. Studies covered a wide range of interventions, including mentoring, counseling, advising, study groups, tutoring, scholarships, orientations, career services, undergraduate research, articulation agreements, and transfer programs. Individually, these studies report positive influences on student success outcomes, including 2- and 4-year graduation, transfer to a 4-year institution, retention, and success in individual courses. However, the number of qualifying studies was surprisingly small, considering the importance of improving success of Latinx students and the length of time during which the problem has been repeatedly emphasized. Few interventions have been undertaken from explicitly assets-based perspectives or theoretical frameworks. The lack of explicit frameworks underlying interventions—combined with a sole/primary focus on students—suggests many interventions were approached from a deficit-based perspective. Further, the study found no pattern of replication studies that might confirm effectiveness of potentially promising interventions. Based on our analysis of evaluations presented in the studies, it does not appear that the research community has developed agreed-upon methods to evaluate commonly agreed-upon outcomes. Finally, no intervention has been sufficiently supported that widespread implementation could be recommended. 相似文献
