Students’ Perceptions of Priorities in Nurse Education: Research Findings and their Curriculum Implications

A credible assumption is that the success of any curriculum intended for adult students is a function of the match between the curriculum and the needs and aspirations of participating students. This assumption provided a basis for investigating the educational priorities of students undertaking nurse education programs in selected N.S.W. colleges of advanced education. The investigation involved a longitudinal study together with several comparative studies. The findings of the studies present a picture of groups of students who are ambivalent towards many of the objectives and priorities of their vocational programs. The origins of that ambivalence appear to reside both in a restricted view of the nurse's role and in anxieties and doubts which students have about their clinical experience and competence. The ambivalence experienced by the students appeared to be working to divert their attention, if not to alienate them altogether, from aspects of their programs and indeed from the vision of nursing which college curricula are intended to foster. Possible responses to the challenges presented by the findings of the studies are canvassed.     

Selective attention of impulsive and reflective children

Kagan's Matching Familiar Figures Test was used to select 36 impulsive and 36 reflective children at each of three grade levels: kindergarten, second, and fifth. An incidental learning paradigm was used to assess the child's recall of central and incidental information. Reflective subjects recalled more central and incidental information than impulsives, suggesting that impulsives have difficulty encoding information for storage. Central recall increased with grade level but incidental learning remained constant, a finding consistent with the developmental trend found in previous investigations. A task order effect was found in the recall of central information with more errors made when the central recall task was presented after the incidental. This order effect may account for the higher central recall scores found in previous investigations. Other problems with the incidental learning paradigms raise questions about the validity of the task for inferring selective attention. Despite the problems associated with the task, the results offer further evidence to support the notion that impulsive and reflective children differ on dimensions other than response latency.     

Knowledge and perceptions of sport psychology within English soccer

The aim of the present study was to examine knowledge and perceptions of applied sport psychology within English soccer. National coaches (n = 8), youth academy directors (n = 21) and academy coaches (n = 27) were surveyed using questionnaire and interview methods. Questionnaire results revealed a lack of knowledge of sport psychology that appeared to underpin some of the most significant barriers to entry for sport psychologists. These included lack of clarity concerning the services of a sport psychologist, problems fitting in and players' negative perceptions of sport psychology. Overall, however, lack of finance was the highest rated barrier. Six barrier dimensions emerged from the interview data: negative perceptions of psychology, lack of sport psychology knowledge, integrating with players and coaching staff, role and service clarity, practical constraints, and perceived value of sport psychology. These findings were broadly compatible with the survey data, with finance emerging as a major barrier and misconceptions of sport psychology being common. Our conclusions are discussed in relation to the practical implications of the study for both applied research and the provision of sport psychology services within English soccer.     

Optimisation of the chain drive system on sports motorcycles

This paper investigates the optimisation of the chain drive system on sports motorcycles. Recently there has been the development of a chain transmission efficiency model that is suitable for motorcycles. The new model is used to predict the efficiency of 600cc sports motorcycle at different speeds. The transmission efficiency is estimated to be between 96 and 99% for speeds less than 75 mile/h. Between 75 and 150 mile/h the transmission efficiency can be as low as 85% due to inertial tension. The transmission efficiency model presented in this paper enables optimisation of sprocket and chain sizes. In general, large sprockets are better at low speeds and smaller sprockets are better at high speeds. The optimum chain size is the chain with the smallest pitch that can meet the torque and power requirement. The sprocket centre distance also has a big effect on efficiency and it is important to use an effective installation procedure. In particular, it is important to set a chain up when the rear wheel axle, front crank and swing arm bearing are all in-line.     

System Performance and Natural Language Expression of Information Needs

Consider information retrieval systems that respond to a query (a natural language statement of a topic, an information need) with an ordered list of 1000 documents from the document collection. From the responses to queries that all express the same topic, one can discern how the words associated with a topic result in particular system behavior. From what is discerned from different topics, one can hypothesize abstract topic factors that influence system performance. An example of such a factor is the specificity of the topic's primary key word. This paper shows that statements about the effect of abstract topic factors on system performance can be supported empirically. A combination of statistical methods is applied to system responses from NIST's Text REtrieval Conference. We analyze each topic using a measure of irrelevant-document exclusion computed for each response and a measure of dissimilarity between relevant-document return orders computed for each pair of responses. We formulate topic factors through graphical comparison of measurements for different topics. Finally, we propose for each topic a four-dimensional summarization that we use to select topic comparisons likely to depict topic factors clearly.
