Dietary and non-dietary correlates of gastrointestinal distress during the cycle and run of a triathlon

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.

Public opinion on school choice: The Detroit metropolitan area

This paper analyzes public opinion on the issue of school choice using telephone survey data from the Detroit metropolitan area. Four choice plans are examined: within-district, cross-district, statewide, and tax-credit. There is substantial support for school choice, the level of support varying with the expansiveness of the choice plan, the geographical area, and the race of the respondent. Overall, the residents of the Detroit metropolitan area, as elsewhere in the United States, are receptive to the idea of school choice, despite the area's history of extreme racial segregation.This paper uses data from the Detroit Metropolitan Area Public Policy Survey (DMAPPS) II Study that was funded and conducted by the College of Urban, Labor, and Metropolitan Affairs of Wayne State University.

Is students’ qualitative feedback changing,now it is online?

Student feedback can be used to enable institutions to achieve the best possible outcomes for students through informing changes which enhance the quality of teaching and learning. Following the introduction of an online survey platform to gather student feedback at a top-performing UK university, anecdotal concerns raised by academics suggested students were being more critical. This exploratory study investigated the effects of switching from a paper to an online survey by comparing the open-ended responses between the two methods of collection. The main contribution of this study is the development of an analytical framework which can be used by other institutions to evaluate student comments, in order to understand and improve the student experience. Three key findings in this study were uncovered. Firstly, the quality of student feedback is not undermined by a switch to a more efficient online collection. Secondly, student comments via both methods of collection predominantly continue to focus on fulfilling basic needs, such as study resources. Finally, a small number of comments online revealed a lack of behavioural constraint and were considered to be inappropriate. These findings have important policy implications for the global higher education sector, highlighting the need for students to be given guidance on providing constructive feedback.     

Building learning communities with distance learning intruction

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.     

Real-Time Feedback on Rater Drift in Constructed-Response Items: An Example From the Golden State Examination

In this study, patterns of variation in severities of a group of raters over time or so-called "rater drift" was examined when raters scored an essay written under examination conditions. At the same time feedback was given to rater leaders (called "table leaders") who then interpreted the feedback and reported to the raters. Rater severities in five successive periods were estimated using a modified linear logistic test model (LLTM, Fischer, 1973) approach. It was found that the raters did indeed drift towards the mean, but a planned comparision of the feedback with a control condition was not successful; it was believed that this was due to contamination at the table leader level. A series of models was also estimated designed to detect other types of rater effects beyond severity: a tendency to use extreme scores, and tendency to prefer certain categories. The models for these effects were found to be showing significant improvement in fit, implying that these effects were indeed present, although they were difficult to detect in relatively short time periods.     

Changes in education in the U.K. and Australia: Common imperatives,predictable outcomes

This paper draws comparisons between the U.K. and Australia (with particular reference to New South Wales) with regard to proposals to a changed school curriculum together with proposed changes in Higher Education. The authors note that the content of the proposed common core curriculum in U.K. schools is very similar to the New South Wales proposal. Further there seems to be little change in the U.K. at least from what was offered there in 1904. In looking at the parallels between the two education systems it is suggested by the authors that there is a hidden agenda particularly in the U.K. Does this hold for Australia as well? The implication is that Australia is following this path. The authors conclude that a divided society is too high a price for us to pay in Australia.     

Achievement Goals During Middle Childhood: Individual Differences in Motivation and Social Adjustment

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.     

Addressing Self‐Injury on College Campuses: Institutional Recommendations

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.
