In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4156 kg, SD = 867, for 3 min; vs. M = 3503 kg SD = 759, for 1 min; p < .001), with no significant differences in delta CK activity between conditions (p = .574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = .55 with a 1-min rest, and r = .45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets. 相似文献

This paper presents the design of a controller based on the block control technique combined with the super twisting control algorithm for trajectory tracking of a quadrotor helicopter. A first order exact differentiator is used in order to estimate the virtual control inputs, which simplifies the control law design. In addition, the wind parameter resulting from the aerodynamic forces is also estimated in order to ensure robustness against these unmatched perturbations. The stability and finite time convergence of the exact differentiator have been recently proved by means of Lyapunov functions, and therefore the stability analysis of the proposed controller has been carried out along the same lines. The performance and effectiveness of the proposed controller are tested in a simulation study taking into account external disturbances. 相似文献

My function is to analyze a survey of adult Jewish education and to present briefly some of my own views on the subject. The survey was planned and conducted under the direction of the National Advisory Council on Adult Jewish Education of the American Association for Jewish Education. The Advisory Council includes the directors or representatives of a number of important religious and lay national Jewish agencies which sponsor adult Jewish education. The responses to the questionnaires were analyzed and the Survey Report was written by Rabbi Samuel I. Cohen. 相似文献

This article analyzes the career commitments and retention patterns among graduates of the DeLeT program (Day School Leadership Through Teaching) who were prepared for day-school teaching at Brandeis University and Hebrew Union College-Jewish Institute of Religion. Employing t-tests to analyze survey responses, we identify factors that shape and support teachers' career commitments to Jewish day schools. Our findings suggest that those who stay in Jewish day school teaching are likely to do so because of more commitment to the Jewish community, greater perception of effective teacher preparation experience, and better school support in comparison to those who leave teaching in this setting. These findings are consistent with a multi-layered understanding of teachers' lives and career commitments, which is illustrated in the interaction between person, program, and setting. 相似文献

The pedagogical work of university supervisors has received little attention in teacher education literature. Based on this concern, this paper provides a conceptual framework for university supervisors, recasting their role as teacher pedagogues focused on responding to the particular contextual needs of student teachers as they learn to teach. Using care, thoughtfulness, and tact as a conceptual framework, the author argues for an interactive and responsive pedagogy of field‐based teacher education grounded in the university supervisor’s concern for the development of the student teacher. 相似文献

ABSTRACTThis article presents ethnographic research on the aspirations of graduates from a private university in New York City, some of whom move to Los Angeles. Findings depict financial and family pressures exerting a governing force upon the graduates’ futures, often beyond their control. Focusing on the narratives of four individuals, we introduce the language of fate as a means of conceptualising the potential repercussions of aspiration and Higher Education. The premise of both is an increased determinacy over one’s future, yet in the high-stakes U.S. context here examined, this financial investment and articulation of family hope may generate fated (seemingly inescapable) and/or fateful (ominous) outcomes. The dynamic of ‘cruel optimism’ illustrates some of the paradoxical consequences of Higher Education, whereby people may be punished by their aspirations. We discuss what factors affect differing outlooks on the future and imply alternative dimensions to adversity beyond the remit of ‘inequality’. 相似文献

ABSTRACTCharles Spearman and L. L. Thurstone were pioneers in the field of intelligence. They not only developed methods to assess and understand intelligence, but also developed theories about its structure and function. Methodologically, their approaches were not that distinct, but their theories of intelligence were philosophically very different – and this difference is still seen in modern approaches to intellectual assessment. In this article, we describe their theories of intelligence and then trace how these theories have influenced the development and use of intelligence instruments, paying particular attention to score interpretation. 相似文献
