The purpose of this investigation was to assess whether pre-race dietary and non-dietary factors were associated with gastrointestinal (GI) distress during the cycle and run of a 70.3-mile triathlon. Fifty three participants recorded dietary details the day before and morning of the triathlon and retrospectively reported GI symptoms from the cycle and run. Occurrence and severity of nausea, regurgitation and fullness were combined into an upper GI (UGI) category, while lower abdominal cramps, flatulence and urge to defecate were combined into a lower GI (LGI) category. Spearman's rho coefficients were used to examine whether UGI and LGI were associated with: (1) pre-race diet (kilocalories, carbohydrate, fibre, fat, protein, caffeine); and (2) non-dietary factors (age, body mass index, experience, weight change, GI distress history, finishing time). Of non-dietary factors, only a history of GI distress showed significant associations with GI symptoms during the triathlon (ρ = .32–.36; P < .05). Morning kilocalorie (ρ = .28, P = .04) and carbohydrate (ρ = .36, P < .01) intakes were modestly, positively associated with UGI during the cycle, while morning caffeine intake (ρ = .30, P = .03) showed a modest positive association with LGI during the run. The associations between diet and GI distress variables remained significant after adjusting for non-dietary factors. Competitors of 70.3-mile triathlons should carefully weigh the benefits of higher race-morning energy, carbohydrate and caffeine intakes against their potential to increase GI distress. 相似文献
Person-centered analyses of achievement goals have been scarce in studies of elementary school children. In this investigation, the authors examined the natural combinations of achievement goals (mastery, performance-approach, performance-avoidance) among 3rd grade students (N = 195) and how clusters differed in self-, teacher-, and peer-reported adjustment variables. Cluster analysis revealed four groups of students: mastery (above average in mastery goals, below average in performance-approach and performance-avoidance goals), multi-goal (above average in all three goals), avoidant (above average in performance-avoidance goals, below average in mastery and performance-approach goals), and low motivation (below average in all three goals). Clusters differed in self-reported academic self-efficacy and perceptions of teacher support, teacher-reported academic competence, and peer nominations of social status. Mastery students had the most adaptive profiles; low motivation, the least adaptive. Avoidant boys had more maladaptive profiles than avoidant girls. 相似文献
The results presented in this study represent only one of four assigned discussion board activities from only one course.
However, these results are not atypical of the amount or nature of student engagement in successive discussion board assignments
to these same 23 graduate students. By the final of the four on-line discussions, student engagement did decrease slightly,
but still remained well above the assigned requirements. Also, similar patterns of high frequency of student involvement were
found in other courses using the same type of on-line discussion board assignments. An additional anecdotal observation was
completed by the course instructor; after the first on-line activity had been completed and the students re-convened on campus
for class, class members appeared more comfortable and more engaged during in class discussions. In summary, the results of
this study indicate that specific types of on-line instruction are capable of developing learning communities among on-line
learners and creating a satisfying learning experience. 相似文献
Nonsuicidal self‐injury is a significant concern on college campuses. Hence, the authors, the International Consortium on Self‐Injury in Educational Settings, offer the current position paper. First, the authors review current research in the field. Next, they discuss considerations for colleges' institutional‐wide response to self‐injury, including the role of and recommendations for relevant stakeholders (students, residence staff, mental health professionals) who directly and indirectly support students who self‐injure. Guidelines for response and suggested resources are also presented. 相似文献

Serial habituation of visual fixations in 2-, 3-, and 4-month-old infants was investigated through a design permitting cross-sectional, within-subject longitudinal, cohort longitudinal, and time-lag analyses. The components of the standard stimulus were displayed individually before and after successive exposures of the standard for familiarization. Relative saliencies of the components for each child were indexed by magnitude of responding to these parts in the initial presentation. Comparisons of the pre- and postexposure fixation times suggest that for all ages habituation was under way to the parts of the stimulus in orders of the relative saliencies. The nature of the data in general did not appear to be influenced significantly by any 1 methodology. 相似文献
The article focuses on the development and assessment of skills during the work‐based placements of business studies sandwich degree students. A total of forty‐two skills are identified and these have been subsumed within two distinct frameworks according to their general or vocational nature. The importance of the work‐based placement In acquiring these skills is borne out when this is compared against a variety of other methods.
Aggregated students’ ratings have been compared with those of employers. Whilst there appears to be some agreement about development having occurred during the placement for virtually all skills, the research highlights major inconsistencies between employers and students in their ratings of the actual level of proficiency finally achieved. This discrepancy between student and employer assessments suggests that a more comprehensive and systematic approach to assessment is required if formal credit is to be given for work‐based learning within degree programmes. This could involve techniques such as triangulation, contract learning or the assessment of competencies, but the difficulty of ensuring a common frame of reference between the parties involved, and across the methods of assessment employed, is likely to remain a major issue, particularly among those advocating formal credit towards degree classifications. 相似文献
Australian volunteer agencies are experiencing a shortage of volunteers along with an ageing workforce population. An examination was made of the current volunteer population at a regional Australian center (St. Vincent de Paul) in relation to recruitment and retention. A 30-question multiple-choice questionnaire examined the factors that affect volunteers’ capacity to engage in work with the agency. The questions were subdivided into the following categories: volunteer demographics; views regarding volunteer work in Australia; volunteer health and wellbeing; and the transport needs of the volunteers. The data were analyzed with a focus on assessing views on volunteer work in Australia. An examination was then made of the impact of chronic health conditions, and areas were identified that may enhance support for volunteers. Although chronic health conditions were not of major concern in this study, further studies are needed to clarify the physical, psychological, and social benefits of volunteering in the regional Australian context. 相似文献
This paper qualitatively compares the responses concerning knowledge about HIV/AIDS prevention methods that were obtained from two cross-culturally different samples of students who were of a sexually active age. Canadian and Zimbabwean education students were sampled. The responses are presented and analyzed with the main purpose of placing the findings in the context of Balmer's (1991) proposal of a unified theory for HIV/AIDS counselling. The major focus of this paper is on HIV/AIDS infection prevention strategies. The differences in responses across the two groups sampled suggest that it would be important to begin individual and group-based prevention strategies with exploration of individual levels of knowledge. Finally, implications for research are discussed. 相似文献
