World Wide Web (WWW) home pages are now ubiquitous for universities around the world. A university home page is the first place that many stakeholders will visit for research on the university or for information on a variety of topics. It was hypothesised that the size and nature of universities and their investment in the staffing of WWW sites will determine the level of output of WWW sites. A WWW-based survey was conducted of Webmanagers at all universities in Australia. A response rate of 80% was achieved. The number of services provided, the number of pages made available and the number of pages that are changed on a regular basis were alternative measures of output. The hypothesised relationships were not supported. The study found that universities are providing a wide range of services with low levels of staffing. 相似文献
This article is about the deaf education methods debate in the public schools of Toronto, Canada. The author demonstrates how pure oralism (lip-reading and speech instruction to the complete exclusion of sign language) and day school classes for deaf schoolchildren were introduced as a progressive school reform in 1922. Plans for further oralist reforms in 1945 brought significant opposition from a deaf political organisation – the Ontario Association of the Deaf (OAD).
The author situates the Toronto battle over methods between progressive educators and deaf people in the longer historical and larger transnational context of debates over oral and manual methods. The author’s examination of the Toronto methods debate raises and answers crucial critical questions about the contested nature of progressive school reforms by examining grassroots responses to reform. The author also places significant emphasis on the effects of reforms on deaf young people who received instruction. The pure oralist method was never as successful for deaf young people as oralists claimed it could be. Yet deaf youngsters felt more ambivalent about the methods than hearing school officials and parents, and deaf adults, did. Historical issues in deaf education that the author examines continue to be controversial today. 相似文献
This article reports on research into the student experience of enquiry in two tasks in a university pharmacy course. Students were required to investigate through a field trip how a community pharmacy operated to meet customer needs and the requirements of the Health System in which it operated. Students were also required to investigate interactions and other properties of particular medicines through an online research task. This study looked at the student experience of enquiry in these contexts and the implications of the findings of that investigation for the debate about how digital literacy might relate to experiences of effective enquiry. The study presents evidence that suggests aspects such as variation in approaches to enquiry are an indicator of the extent of student success rather than the technologies ‘per se’. Analysis of the student population data, interviews and open-ended comments in surveys identified qualitatively different experiences of enquiry in both the community pharmacy context and the online investigation. The outcomes suggest that the way students approach and conceive of enquiry is closely related to the quality of their outcomes, and that this appears to be a more significant factor in the nature of effective enquiry than their classification as digital natives as a result of their age. 相似文献
Through poetry and strips of narrative, this paper discusses the embodied experience of chemical sensitivity and the anthropologist author's and other patients' journey through altered perception towards knowledge, community and transformation in the context of a medical clinic. The narratives are situated in several strands of relevant theory, including Merleau‐Ponty's work on the primacy of perception, feminist perspectives on embodied experience and standpoint epistemology, disability studies, identity creation through narrating the self, and Lave and Wenger's situated learning in a community of practice. 相似文献
Abstract Stroboscope photography and accelerometry techniques were used to measure rebound velocities of tennis balls from impact locations on the strings and vibration levels at the rotation point on the racket handle for both conventional and oversized tennis rackets. The oversized rackets demonstrated lower vibration levels and higher rebound velocities than their conventional counterparts when balls struck by the racket were compared along a transverse axis drawn perpendicular to the racket shaft and through the geometric center of the strings. These differences were, however, only significantly different (p < .01) at the impact location 6 cm along this axis toward the top edge of the racket. Higher rebound velocities were recorded at all impact points from the oversized rackets along the axis in line with the racket shaft. Significantly lower vibration levels were apparent at locations 4 cm, 6 cm, and 8 cm from the string center away from the racket handle. The lower vibration levels, particularly at the extremes of the racket face, in conjunction with higher rebound velocities, support the concept that this new racket design is of practical benefit to users. 相似文献
The study examined the prevalence of overweight cases in a sample of 151 deaf children aged 6-11 years. Participants were deaf students attending six elementary schools, both regular and special, in four states. Body mass index (BMI) was calculated using height and weight, plotted on the Center for Disease Control and Prevention (CDC) U.S. BMI-for-age growth charts, then compared to national values for same age and gender (CDC, 2006a, 2006b; National Center for Health Statistics, 2005). The results indicated that the prevalence of overweight deaf children aged 6-11 years was above the national percentage for same age and gender. A larger percentage of boys was overweight (24.7%) than girls (20.4%). After age 8 years, girls showed a consistent decrease in BMI with increasing age, a trend not demonstrated by boys. As a group, deaf children demonstrate a higher prevalence of overweight than national averages. 相似文献
The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States learned novel categories with features that were easy (e.g., “red”) or difficult (e.g., “mauve”) to name. Adults (d = 1.06) and—to a lesser extent—children (d = 0.57; final training block) learned categories composed of more nameable features better. Children's knowledge of difficult-to-name color words predicted their learning for categories with difficult-to-name features. Rule-based category learning may be supported by the emerging ability to form verbal hypotheses. 相似文献
In this study, we investigated the impact of a controlled 4-day caffeine withdrawal period on the effect of an acute caffeine dose on endurance exercise performance. Twelve well-trained and familiarized male cyclists, who were caffeine consumers (from coffee and a range of other sources), were recruited for the study. A double-blind placebo-controlled cross-over design was employed, involving four experimental trials. Participants abstained from dietary caffeine sources for 4 days before the trials and ingested capsules (one in the morning and one in the afternoon) containing either placebo or caffeine (1.5 mg · kg(-1) body weight · day(-1)). On day 5, capsules containing placebo or caffeine (3 mg · kg(-1) body weight) were ingested 90 min before completing a time trial, equivalent to one hour of cycling at 75% peak sustainable power output. Hence the study was designed to incorporate placebo-placebo, placebo-caffeine, caffeine-placebo, and caffeine-caffeine conditions. Performance time was significantly improved after acute caffeine ingestion by 1:49 ± 1:41 min (3.0%, P = 0.021) following a withdrawal period (placebo-placebo vs. placebo-caffeine), and by 2:07 ± 1:28 min (3.6%, P = 0.002) following the non-withdrawal period (caffeine-placebo vs. caffeine-caffeine). No significant difference was detected between the two acute caffeine trials (placebo-caffeine vs. caffeine-caffeine). Average heart rate throughout exercise was significantly higher following acute caffeine administration compared with placebo. No differences were observed in ratings of perceived exertion between trials. A 3 mg · kg(-1) dose of caffeine significantly improves exercise performance irrespective of whether a 4-day withdrawal period is imposed on habitual caffeine users. 相似文献
Group status was examined as a moderator of peer group socialization of deviant, aggressive, and prosocial behavior. In the fall and 3 months later, preadolescents and early adolescents provided self-reported scores for deviant behavior and group membership, and peer nominations for overt and relational aggression, prosocial behavior, and social preference. Using the social cognitive map, 116 groups were identified involving 526 children (282 girls; M age=12.05). Hierarchical linear modeling revealed that high group centrality (visibility) magnified group socialization of relational aggression, deviant behavior, and prosocial behavior, and low group acceptance magnified socialization of deviant behavior. Results suggest group influence on behavior is not uniform but depends on group status, especially group visibility within the larger peer context. 相似文献
