The cadence that maximises power output developed at the crank by an individual cyclist is conventionally determined using a laboratory test. The purpose of this study was two-fold: (i) to show that such a cadence, which we call the optimal cadence, can be determined using power output, heart-rate, and cadence measured in the field and (ii) to describe methodology to do so. For an individual cyclist's sessions, power output is related to cadence and the elicited heart-rate using a non-linear regression model. Optimal cadences are found for two riders (83 and 70 revolutions per minute, respectively); these cadences are similar to the riders’ preferred cadences (82–92?rpm and 65–75?rpm). Power output reduces by approximately 6% for cadences 20?rpm above or below optimum. Our methodology can be used by a rider to determine an optimal cadence without laboratory testing intervention: the rider will need to collect power output, heart-rate, and cadence measurements from training and racing sessions over an extended period (>6 months); ride at a range of cadences within those sessions; and calculate his/her optimal cadence using the methodology described or a software tool that implements it.  相似文献

Inaugural Essay     
New to the Journal of Archival Organization, the “Technology matters in archives” column examines how technology affects archives and archivists. This inaugural column explains the nature of the column and sets the stage for topics and issues that it will address. It examines the meaning of the term technology. Further, the column explores the notion of technological dependence-- not just dependence on digital or electronic systems--as a lens in which to examine the archival enterprise in grappling with twenty-first century issues. Concluding with the suggestion that technology can be considered from three categorical points of view: soft (philosophical approaches and practices), medium (codified processes, guidelines and standards) and hard technology (hardware and software).  相似文献

Purpose

The study evaluates how providers give patient education materials and identifies improvements to comply with Meaningful Use (MU) requirements.

Methods

Thirty-eight patient-provider interactions in two health care outpatient clinics were observed.

Results

Providers do not uniformly know MU patient education requirements. Providers have individual preferences and find gaps in what is available. Accessing and documenting patient education varies among providers. Embedded electronic health record (EHR) materials, while available, have technical access barriers.

Conclusions

Providers'' EHR skills and knowledge levels contribute to non-standardized patient education delivery.  相似文献

Classroom discourse patterns were examined in the morning news sessions of a primary school classroom. The effects of reducing teacher questions and increasing rates of teacher pauses, praise and directives were investigated. Child words spoken and child expansions were recorded, as well as class call‐outs and teacher control statements. Frequencies of child words spoken showed no significant changes across the phases of the study. However, reducing teacher questions and increasing teacher pauses significantly decreased child expansions, while reducing teacher questions and increasing teacher praise significantly increased child expansions. Replacing teacher questions with directives had no significant effect upon child expansions. Class call‐outs and teacher control statements showed no significant changes across the intervention phases. The results of this study suggest that, for this teacher and class, teacher questions may be decreased without adversely affecting either child utterances or class behaviour, and that replacing questions with praise may increase children's contributions — particularly in the form of verbal expansions — to morning news talks.  相似文献

This paper reveals the complex diversity that underpins ostensibly similar transnational education programmes (TNE), through a comparison of UK TNE in Malaysia and Hong Kong. It draws on data from two different yet cognate studies on the role of UK universities in delivering higher education in Asia. Some fine-grained and informative differences between the ways in which ‘value’ in TNE is constructed in different host contexts is revealed. The paper brings to light the ‘voices’ of TNE students and graduates, which are very seldom heard. The arguments adapt and extend the concepts of education as a positional good, and as cultural capital. For various instrumental, intrinsic and personal reasons the authors discuss in detail, UK TNE is more highly valued in Malaysia than in Hong Kong. The paper makes a wider contribution to knowledge on the changing landscape of international higher education and the impact on social and personal (dis)advantage.  相似文献

This study examines sources of satisfaction, indicators of stress, academic performance, and reward structure in the academic careers of male and female faculty at a major midwestern state university. Faculty pairs were selected from five academic divisions. A total of 58 matched pairs were identified. Of these, 63 faculty responded, yielding data for 23 matched pairs. Subjects were mailed the Academic Career Development Survey, consisting of 144 items. Results indicated that self-reported physical and mental health, and professional and personal life satisfaction were high for both males and females. Both males and females placed high importance on their career and on marriage/other intimate relationships; however, both reported high levels of dissatisfaction with these factors. Gender differences were found in both satisfaction and type of stress reported; no gender differences were found in composite teaching and research performance indices. Salary data, obtained for 42 matched pairs, indicated similar salary levels for men and women. Results were discussed with respect to prior research on gender differences and the academic career.  相似文献
