Abstract The purpose of this study was to determine the effects of a Nautilus circuit weight training program on muscular strength and maximal oxygen uptake ([Vdot]O 2 max) by comparing these effects to those produced by adhering to either a free weight (FW) strength training program or a running (R) program. Male college students who voluntarily enrolled in either a FW training class (n = 11), a Nautilus (N) circuit weight training class (n= 12), or a R conditioning class (n= 13) were subjects for this investigation. All groups participated in their respective programs 3 days per week for 10 weeks. Strength was assessed using a Cybex II isokinetic dynamometer set at an angular velocity of 60° · s ?1 and a damping of 2. The FW group served as the control group for the assessment of [Vdot]O 2 max changes, while the R group served as controls for the assessment of strength differences. ANCOVA revealed that the N and R groups experienced significant (p < .01) increases in [Vdot]O 2 max expressed in L · min ?1 (10.9 and 11.4%), ml · kg ?1 · min ?1 (10.8 and 11.7%), and ml · kgLBW ?1 · min ?1 (7.1 and 7.5%) when compared to the FW group. There were no significant differences between the N and R groups. There were no significant differences among groups in final peak torque values (after covariance), and torque at the beginning and end of the range of motion for the knee extensors, knee flexors, elbow extensors, and elbow flexors. In general, isokinetic strength values elicited by the N group compared favorably to those generated by the FW group. It was concluded that for a training period of short duration, Nautilus circuit weight training appears to be an equally effective alternative to standard free weight (strength) and aerobic (endurance) training programs for untrained individuals. 相似文献

Students filling out the FAFSA list colleges and universities where they wish their data, sent. Until recently, colleges were provided this list, and the practice was suspended, given concerns that colleges were using the list to strategically allocate aid. Using the, 2011–2012 NPSAS, we analyze student financial aid packages to determine if list position, affects aid. We find little evidence that it does. 相似文献

Recent studies in the tradition of Schmookler have re-emphasised the potential role of demand in stimulating innovation. Here, we reconsider the role of ‘home’ and ‘export’ market demand in stimulating manufacturing innovation using comparable panel data for two small open economies - Ireland and Switzerland. Our analysis is based on the estimation of reduced form innovation production functions using panel data estimators over the sample period 1994-2005. For a range of innovation indicators, however, we find little evidence of any significant market demand effects, with innovation performance instead determined largely by firm-level capability effects and characteristics. In policy and strategy terms this suggests the continued value of measures to improve innovation capability regardless of market demand conditions. In more methodological terms our results suggest the validity of the usual assumption implicit in modelling innovation outputs that supply-side factors predominate. 相似文献

作为“得”字句的一个小类 ,“主事居后‘得’字句”具有重要的句法语义特点。从语篇角度出发来进行考察 ,可以发现该句式的典型式为 :P ,V1得NV2 ,P是不容忽视的组成部分。该句式在语义上表达的是一个致使关系串 ;在语用上具有保持话题同一性的功能。这种句式意义和语用功能 ,正是“主事居后”的决定因素 相似文献

改进了传统的信噪比文本分类方法。提出了一种改进的基于信噪比的文本分类方法。它考虑了禁用词的排除、近义词和同义词的合并以及特征项在文本中不同位置对文章分类的贡献不同。 相似文献

当前,在对教育公平的讨论中,人们往往忽视了对现有教育不公平下的弱势群体、乃至对过去不公平教育政策下的利益受损者进行必要补偿。对弱势群体进行"积极补偿"是教育公平自身的必然要求,是公共行政的应有责任,并有着明确的法律依据和现实意义。参照美国半个世纪以来有关积极补偿的教育政策,我们可以对积极补偿的对象、范围和方式做出清晰认定。 相似文献

Six years have gone by since the passing of No Child Left Behind (2002) and due to the ‘high-stake’ riders attached to this legislation, educators at all levels have found themselves in
a state of both emotional and cognitive dissonance. Recent research in the field of neuroscience combined with principles
gained from constructivism support the importance of developing and implementing both a child-centered curriculum and a positive
learning environment that is appropriate for young children. This paper addresses some of the difficulties that arise from
the No Child Left Behind act and teaching from a constructivist model. Additionally, positive suggestions are provided for the early childhood educator
in order to support current teaching philosophies despite the pressures of high-stakes testing. 相似文献
