While the female activewear market is growing rapidly, research on activewear consumption and female consumers is lagging. Existing researchers have failed to produce an in-depth understanding of female consumers’ perceptions of activewear, thereby providing limited insights for the activewear industry. Drawing upon brand association theory and the functional, expressive, and aesthetic model, the authors identify important attributes of activewear brands and how attributes lead to benefits pursued by female activewear consumers. Focus groups were conducted with 72 female activewear consumers in Australia. Findings reveal three product-related attributes (functional design, colour, and size and fit) and two non-product-related attributes (price and model imagery) influence the fulfillment of four benefits (mood enhancement, exercise facilitation, healthy and active lifestyle, and physical fit body image). This research contributes theoretical and empirical knowledge about activewear consumption and the vertical structure of brand associations. Findings of this research can help activewear brands deliver benefits to female consumers through improved product designs and marketing strategies.  相似文献

The German education system does not traditionally rely on standardized testing. However, when the Programme for International Student Assessment (PISA) study revealed an average performance of German students compared to other participating countries, a particular proportion of low-performing students, and remarkable disparities between the federal states, German policy makers decided for a major reform of the education system. A core piece of this reform was the introduction of National Education Standards. For science education, these standards were heavily influenced by the PISA results and its underlying framework. That is, with the standards, a paradigm shift took place from the German notion of Bildung towards the Anglo-American notion of literacy. With the introduction of these standards, a new field of empirical educational research was created: research on models of scientific literacy or competency models as a basis of benchmarking the standards. This article describes the German education system before PISA, summarizes the major findings from PISA, and describes how these findings informed the formulation of the performance standards for science education. It also details the measures undertaken to benchmark these standards. Finally, it provides insight into the issues with developing and benchmarking performance standards and points out future areas of research on evidence-based decision making in educational policy.  相似文献

Particularly in primary school, good performance on copy tasks is an important working technique. With respect to writing skills, copying is a very basic process on which more complex writing abilities are based. We studied the copying ability of second and fourth graders across four types of symbols which vary with respect to their semantic and phonological characteristics: arbitrary graphical objects, unpronounceable consonant strings, numerals and meaningful text. Results show, in terms of average copying speed, significant effects of both factors: fourth graders performed generally faster than second graders, and for both class levels, the number of copied characters per time decreased from meaningful text to graphical objects, all pair-wise contrasts between symbol types being statistically significant. Moreover, a significant interaction shows that fourth graders improved more when copying symbols that form pronounceable chunks, namely meaningful text and numerical strings. This indicates an increasing role of phonological (and probably also semantic) processes involved in copying across primary school.  相似文献

The relation between autonomy support and basic need satisfaction was investigated by applying a longitudinal design at a time interval of two years, and by comparing two different grade level cohorts of students. Participants comprised 1.225 Norwegian students divided by two subsamples (6th and 8th grade level/8th and 10th grade level). The results showed stationary effects of autonomy support and basic need satisfaction, respectively, from Time 1 to Time 2. There was also evidence of a causal effect from T1 to T2 between autonomy support and basic need satisfaction, and reciprocal causation from basic need satisfaction T1 to autonomy support T2. These effects were grade level and gender specific. The present study provided support for longitudinal relations between autonomy support and basic need satisfaction. Autonomy support and basic need satisfaction are both antecedents to and consequences of themselves, also when measured at long term intervals.  相似文献

“This paper aims to present a critical analysis of the Year 1 Phonics Screening Check (PSC), with special focus on the relationship between the UK Department for Education's policy‐making and the evidence considered in the process of developing and evaluating the PSC. The reports from the in‐house Standards and Testing Agency and from commissioned external organisations with limited remits have been analysed, with emphasis on how the screening check findings have been used in DfE decision‐making. My conclusion is that the department has overestimated both the validity and the reliability of the check: partly because important sources of measurement error have not been explored, and partly because the available evidence has not been analysed in sufficient depth — or perhaps simply been ignored by the department. The whole phonics screening check seems to be the product of policy‐based evidence, rather than evidence‐based policy‐making. This has, in my view, seriously undermined the value of the PSC as a screening instrument, and one must wonder whether it is ‘fit for purpose’.  相似文献

The stiffness measuring method for bicycle frames is not standardized, leading to a wide variety of test setups; they differ in many aspects such as applied load, support constraints and frame deflection measurement. The aim of this paper is to draw attention to this problem and to quantify the perturbing, unwanted side effects that influence the stiffness measurement of the bicycle frame. This is illustrated by developing a multi-purpose rating test method for bicycle frame stiffness. The proposed test rig design considers different aspects which should be taken into account when measuring the bicycle frame stiffness. In the experimental setup, it is observed that the contribution of the test bench compliance led to 21% difference in the frame stiffness results; the influence due to the head, the tube-bearing type the corresponding preload resulted in up to 19% difference in the stiffness results between the lowest and highest stiffness values measured; hysteresis effects caused by pulleys are estimated to introduce errors up to 11%; and the influence due to the operator variability and sensor accuracy is estimated to be less than 3%.  相似文献

Abstract

The assessment of nutrition and activity in athletes requires accurate and precise methods. The aim of this study was to validate a protocol for parallel assessment of diet and exercise against doubly labelled water, 24-h urea excretion, and respiratory gas exchange. The participants were 14 male triathletes under normal training conditions. Energy intake and doubly labelled water were weakly associated with each other (r = 0.69, standard error of estimate [SEE] = 304 kcal · day?1). Protein intake was strongly correlated with 24-h urea (r = 0.89) but showed considerable individual variation (SEE = 0.34 g · kg?1 · day?1). Total energy expenditure based on recorded activities was highly correlated with doubly labelled water (r = 0.95, SEE = 195 kcal · day?1) but was proportionally biased. During running and cycling, estimated exercise energy expenditure was highly correlated with gas exchange (running: r = 0.89, SEE = 1.6 kcal · min?1; cycling: r = 0.95, SEE = 1.4 kcal · min?1). High exercise energy expenditure was slightly underestimated during running. For nutrition data, variations appear too large for precise measurements in individual athletes, which is a common problem of dietary assessment methods. Despite the high correlations of total energy expenditure and exercise energy expenditure with reference methods, a correction for systematic errors is necessary for the valid estimation of energetic requirements in individual athletes.  相似文献

Political theorists like Alexis de Tocqueville have long recognized the importance of citizen associations for the practice of democracy. Through participation in associations, citizens both receive an education in public affairs and create centers of political power independent of the state. Essential to participation in an association is participation in a forum, a communication space that allows for many-to-many communication in which citizens can "treat of public affairs in public" (Tocqueville, 1945, p. 109). Participation in forums suffers from numerous barriers, however, such as the need to meet in one common place, the need to meet at one common time, and the potentially high costs of participation. Online forums on the Internet avoid many of these barriers, and thus they hold the promise of facilitating the formation and operation of citizen associations. This was confirmed in 1995 by the experiences of a Boston-based citizen association, the Telecommunication Policy Roundtable-Northeast (TPR-NE). TPR-NE's uses of the Internet suggest that online forums may allow associations to be more responsive, more robust, and able to unite more members.  相似文献
