This paper considers the role of library support for distance learning activities at the University of Surrey, with specific reference to the MA in Linguistics (TESOL) and the MSc in English Language Teaching Management. These courses represent a major challenge to support services for distance learners, as the students have no face‐to‐facc contact with staff, and most of them live and work overseas. Firstly the courses are described as operating along a number of clines that define a distance learning operation, and the issue of resource support is considered. We then turn to the role of the library in supporting distance learning students, and consider the ways in which the role of the library in distance learning programs is expanding and changing to meet the challenges of the future. The specific example of the Distance Learners’ Information Service (DiLIS) of the George Edwards Library (GEL) is presented as an example of good practice.  相似文献

This study used data from the Minnesota Longitudinal Study of Risk and Adaptation (= 267) to investigate whether abuse and neglect experiences during the first 5 years of life have fading or enduring consequences for social and academic competence over the next 3 decades of life. Experiencing early abuse and neglect was consistently associated with more interpersonal problems and lower academic achievement from childhood through adulthood (32–34 years). The predictive significance of early abuse and neglect was not attributable to the stability of developmental competence over time, nor to abuse and neglect occurring later in childhood. Early abuse and neglect had enduring associations with social (but not academic) competence after controlling for potential demographic confounds and early sensitive caregiving.  相似文献

Despite the research examining various production aspects of broadcast sport, scholars have generally overlooked a ubiquitous sonic component of broadcasts—spectators’ aural response (i.e., crowd noise). Such cues can act as a heuristic to influence perceptions of competition, particularly in the absence of visuals. Using continuous response measurement, this experiment demonstrates how mediated spectator response in the form of crowd noise yields enhanced perceptions of the exciting nature of broadcast sport, although the effect is diminished in televised sports. Implications are suggested for contemporary sport consumption, where aural cues can draw attention to game events in multi-screen viewing scenarios.  相似文献

There is a need for effect sizes that are readily interpretable by a broad audience. One index that might fill this need is π, which represents the proportion of scores in one group that exceed the mean of another group. The robustness of estimates of π to violations of normality had not been explored. Using simulated data, three estimates of π (π? direct, r, and rrobust) were studied under varying conditions of sample size, distribution shape, and group mean difference. This study demonstrated that r and rrobust were biased estimates of π when data were nonnormal. We recommend that neither be used in estimating π unless data are normally distributed.  相似文献

We describe a tutorial tool which allows the execution of a C program to be graphically displayed. VINCE (Visual Instruction for Novices in a C Environment) is written in Java, allowing it to be used on the web. The student can enter their own C code, or select from a menu of pre-written tutorials, each illustrating a particular aspect of programming. The tool provides a simulated map of the computer's memory, showing where pointers and variables are stored. The map is dynamically updated as the program is executed. Explanatory notes for each step are provided. The program's function stack may be viewed. At present, the tool can only deal with syntactically correct C code. The package may be used at http://alife.mic.dundee.ac.uk/growe/VINCE/tutorial01.html  相似文献

The authors report on a national survey of administrators and program specialists at 43 state vocational rehabilitation (VR) agencies concerning the impact of federal employment legislation and rehabilitation policies on the provision of services to consumers who are deaf or hard of hearing. The article focuses on 5 initiatives enacted to enhance efforts to help people with disabilities achieve competitive employment and self-sufficiency: the Workforce Investment Act of 1998, Order of Selection policies established by state agencies, Interagency Agreements between VR and postsecondary programs, the Comprehensive System of Personnel Development, and the Ticket to Work and Work Incentives Improvement Act of 1999. The article concludes with a summary of state agencies' priorities and needs in regard to technical assistance to enhance the provision of VR services.  相似文献

BackgroundHigh-intensity interval training (HIIT) induces similar or even superior adaptations compared to continuous endurance training. Indeed, just 6 HIIT sessions over 2 weeks significantly improves maximal oxygen uptake (VO2max), submaximal exercise fat oxidation, and endurance performance. Whether even faster adaptations can be achieved with HIIT is not known. Thus, we aimed to determine whether 2 sessions of HIIT per day, separated by 3 h, every other day for 5 days (double HIIT (HIIT-D), n = 15) could increase VO2max, submaximal exercise fat oxidation, and endurance capacity as effectively as 6 sessions of HIIT over 2 weeks (single HIIT (HIIT-S), n = 13).MethodsEach training session consisted of 10 × 60 s of cycling at 100% of VO2max interspersed with 75 s of low-intensity cycling at 60 watt (W). Pre- and post-training assessments included VO2max, time to exhaustion at ∼80% of VO2max, and 60-min cycling trials at ∼67% of VO2max.ResultsSimilar increases (p < 0.05) in VO2max (HIIT-D: 7.7% vs. HIIT-S: 6.0%, p > 0.05) and endurance capacity (HIIT-D: 80.1% vs. HIIT-S: 79.2%, p > 0.05) were observed. Submaximal exercise carbohydrate oxidation was reduced in the 2 groups after exercise training (HIIT-D: 9.2%, p = 0.014 vs. HIIT-S: 18.8%, p = 0.012) while submaximal exercise fat oxidation was significantly increased in HIIT-D (15.5%, p = 0.048) but not in HIIT-S (9.3%, p = 0.290).ConclusionSix HIIT sessions over 5 days was as effective in increasing VO2max and endurance capacity and was more effective in improving submaximal exercise fat oxidation than 6 HIIT sessions over 2 weeks.  相似文献

Abstract

Beginning in the early 1980s, the Computer Science Department at Carnegie Mellon University developed and used three generations of novice programming environments. The focus of these systems was to apply, advance and tune structure editor technology in support of the teaching and learning of computer programming. The use of these pedagogical systems in Carnegie Mellon's introductory programming courses provided feedback and inspiration to guide the projects. This paper tracks the evolution of the programming environments and courses, documenting important lessons and discoveries about novice programmers and the environments that support them.  相似文献

This study examined the extent to which the biological sex of nurse‐physician interactants related to the interpersonal communication satisfaction experienced by the nurse. The sample included 153 male and female nurses. Results indicated that same‐sex interactions are more satisfying for female nurses, while mixed‐sex interactions are more satisfying for male nurses. Nurses reported greater communication satisfaction when interacting with female physicians.  相似文献
