ABSTRACT The aims of this study were to compare the force profile of using a horizontal cylinder-shaped axis or a vertical cone-shaped axis to provide resistance in rotary inertia devices, and to report the evolution of kinetic and kinematic variables in experienced athletes during a half-squat exercise. Twenty-two healthy active men participated in the assessment of time, peak velocity, peak force, time to reach the peak force, average force, impulse, and range of movement, during a half-squat incremental test performed on conical inertial device (CP) and on cylinder inertial device (YY). The analysis showed that YY during CON-ECC phased generates substantial higher peak_force, mean_force, impulse, time, and a lower peak_velocity, than CP. We never obtained eccentric overload for peak_force or mean_force. CP offers less resistance to accelerate-decelerate the movement with respect to YY, we need checking whether eccentric overload it is being produced, and the impulse was the only kinetic variable that was able to discriminate between the inertias and devices. 相似文献

This study examines the self-concept of criminology and criminal justice students, vis-`a-vis the perceptions held of them by non-criminology and criminal justice students, using a framework of symbolic interactionism. The data in this study were obtained from a sample of both criminology and criminal justice students and non-criminology and criminal justice students attending a large state university in north Texas. The findings reveal a lack of consensus among perception patterns held by criminology and criminal justice students and non-criminology and criminal justice students. Implications regarding the future of criminology and criminal justice education follow. 相似文献

The goal of this research is to identify science teachers' beliefs and conceptions that play an important role in shaping their understandings of and attempts to enact inclusive science teaching practices. We examined the work products, both informal (online discussions, email exchanges) and formal (papers, unit plans, peer reviews), of 14 teachers enrolled in a master's degree course focused on diversity in science teaching and learning. These emerging understandings were member-checked via a series of interviews with a subset of these teachers. Our analysis was conducted in two stages: (1) describing the difficulties the teachers identified for themselves in their attempts to teach science to a wide range of students in their classes and (2) analyzing these self-identified barriers for underlying beliefs and conceptions that serve to prohibit or allow for the teachers' understanding and enactment of equitable science instruction. The teachers' self-identified barriers were grouped into three categories: students, broader social infrastructure, and self. The more fundamental barriers identified included teacher beliefs about the ethnocentrism of the mainstream, essentialism/individualism, and beliefs about the meritocracy of schooling. The implications of these hurdles for science teacher education are discussed. 相似文献

In this paper we investigate the link between the language in which pupils take the Programme for International Student Assessment (PISA) test and the scores they achieve in this assessment, focusing upon the case of Wales. Using five rounds of PISA data and an instrumental variable approach, we show how pupils who took the test in Welsh score around 0.3 standard deviations (30 PISA test points) lower in reading, mathematics and science than their peers who took the test in English. This finding is robust to different model specifications and statistical approaches. We argue that this may indicate that the academic performance of teenagers in Wales may be underestimated in PISA – particularly amongst those who take this test in Welsh. 相似文献

Parents evaluate the reputations of the schools when making judgements about their desirability. They try to approximate the quality of schools and the social environment and contrast those with their hopes and fears concerning their child’s education. We aim to clarify how the reputations of schools are constructed in Finland and Chile and what sorts of reputational categories, hierarchies and preferences of schools and classes families form when making a choice. Bernstein’s instrumental and expressive orders are applied as tools to analyse these reputations from qualitative interview data. The amount and type of expressive order turned out to be the crucial factor when comparing schools’ reputations and in the making of choices. While in Chile the expressive-social order in terms of contributing to habitus was seen as the most important factor in constructing school reputations and shaping preferences, in Finland the expressive-personal order in the form of school contentment was highlighted. 相似文献
