Biomechanics and motor control researchers measure how the body moves and interacts with its environment. The aim of this review paper is to consider some key issues in research methods in biomechanics and motor control. The review is organized into four sections: proposing, conducting, analysing and reporting research. In the first of these, we emphasize the importance of defining a worthy research question and of planning the study before its implementation to prevent later difficulties in the analysis and interpretation of data. In the second section, we cover selection of trial sizes and suggest that using three trials or more may be beneficial to provide more 'representative' and valid data. The third section on analysis of data concentrates on effect size statistics, qualitative and numerical trend analysis and cross-correlations. As sample sizes are often small, the use of effect size is recommended to support the results of statistical significance testing. In using cross-correlations, we recommend that scatterplots of one variable against the other, with the identified time lag included, be inspected to confirm that the linear relationship assumption underpinning this statistic is met and, if appropriate, that a linearity transformation be applied. Finally, we consider important information related to the issues above that should be included when reporting research. We recommend reporting checks or corrections for violations of underpinning assumptions, and the effect of these checks or corrections, to assist in advancing knowledge in biomechanics and motor control. 相似文献

This mixed-method study examines Arizona principals’ capacity-building skills and practices in Tier III schools aimed at developing potential for sustained improvements in student outcomes. Data sources included surveys (62 individuals) and semistructured interviews (29 individuals) of principals and staff (e.g. teachers, instructional coaches, assistant principals) who participated in grant-funded leadership training over an 18-month period. The theoretical framework consisted of leadership in the sociocultural dimension (Ylimaki et al. in Leadersh Policy Sch 11(2):168–193, 2012) and capacity building for sustainable improvement in high-capacity Schools (Mitchell and Sackney in Sustainable improvement: building learning communities that endure. Sense Publishers, Rotterdam, 2009). Findings indicated that: (1) schools were not at high-levels of capacity building; (2) those schools in process of building capacity for sustainable improvement demonstrate a directive leadership approach; (3) school development towards high capacity focused on micro-level processes (e.g., professional learning communities); and (4) little attention was given to leadership in the socio-cultural dimension. Implications of the study suggest future research test a leadership development model for Tier III schools that links capacity building leadership and student achievement. The next generation of educational leaders must also have the knowledge, skills, dispositions, and analytical tools to lead schools in both the accountability culture and the macro socio-cultural dimension. 相似文献

Menarche is a significant milestone for young women, representing an important juncture between girlhood and maturation. The limited literature that exists suggests that a mother's reaction to her daughter's first periods can shape her experiences and perceptions of menstruation which, in turn, may impact on her self-image and, consequently, sexual risk taking. However, very little is known about UK mothers' attitudes towards their daughters' menarche. This paper aims to add to the body of knowledge by applying a postmodern critique, a Derridian deconstructive analysis, to a discussion thread found on mumsnet.com – a UK parenting website. The thread is concerned with a mother's response to her daughter's menarche to which other mothers respond. The deconstruction revealed a number of meta-narratives and themes within the text: secrecy, sorrow, a lack of competency and knowledge, power, gender and motherhood. Unwittingly, the women appear to be socialising their daughters to comply with and perpetuate the menstrual taboo that they endured themselves, thus repeating the cycles of shame associated with menstruation. The findings of this critique suggest that menstrual education is an area that requires more attention, particularly in the context of perceived menstrual shame and its impact on sexual decision-making. 相似文献

In this study we examined alternative item types and section configurations for improving the discriminant and convergent validity of the GRE General Test. A computer-based test of reasoning items and a generating-explanations measure was administered to a sample of 388 examinees who previously had taken the General Test. Confirmatory factor analyses indicated that three dimensions of reasoning—verbal, analytical, and quantitative—and a fourth dimension of verbal fluency based on the generating-explanations task could be distinguished. Notably, generating explanations was as distinct from new variations of reasoning items as it was from verbal and quantitative reasoning. In the full sample, this differentiation was evident in relation to such external criteria as undergraduate grade point average (UGPA), self-reported accomplishments, and a measure of ideational fluency, with generating explanations relating uniquely to aesthetic and linguistic accomplishments and to ideational fluency. For the subset of participants with undergraduate majors in the humanities and social sciences, generating explanations added to the relationship with UGPA over that contributed by the General Test. 相似文献

In recent experiments in which the social influences on feeding in Mongolian gerbils were investigated, observer gerbils acquired food preferences from conspecific demonstrators only if the demonstrators and observers were either related or familiar. Even then, the effects of demonstrator gerbils on observers’ food choices lasted less than 24 h. In similar experiments with Norway rats, the familiarity/relatedness of demonstrators and observers had little effect on social learning, and the demonstrators’ influence on observers’ food choices lasted many days. We examined the causes of these differences and found that, after observer gerbils interacted with either unfamiliar or familiar conspecific demonstrators that had been fed using procedures typically used to feed demonstrator rats, they showed long-lasting social learning about foods, whereas observer rats interacting with conspecific demonstrators that had been fed as demonstrator gerbils normally are fed showed effects of familiarity/relatedness to demonstrators on their social learning about foods. Procedural differences, rather than species differences, seem to be responsible for reported inconsistencies in social learning about foods by rats and gerbils. 相似文献

There is more to developing effective exhibitions than following a particular process model. The Fort Worth Museum of Science and History utilizes a strategy that includes a clearly articulated framework of core purpose and values, development teams that think systemically and focus on maintaining positive relationships, along with the help of outside experts, professional literature, and visitor feedback to continually infuse the team's thinking. This strategy has led to exhibits that more clearly reflect the institution, and at the same time are deemed extraordinary learning environments by two important stakeholders: the advisors whose content and technical expertise supported the project, and by visitors. 相似文献
