Research on academic achievement at a university has mainly focused on success and persistence among first year students. Very few studies have looked at delay or failure in the completion of a final dissertation. However, this phenomenon could affect a substantial proportion of students and has considerable costs. The purpose of the present study is to identify factors which predict postponement in the completion of the final dissertation. Several potential predictors (e.g., background, personality, social support, motivational beliefs, and engagement) were selected through an integrative review of the literature on achievement in higher education. A questionnaire assessing these variables was administered to 341 students a few months before the deadline for their final dissertation. Results indicate that perceived peer support, perceived relatives support, role conflict, and age have an independent and significant effect on whether or not the final dissertation is completed on time. In addition, self-efficacy and behavioral engagement appeared to be mediators of the relationship between the social support and the final dissertation completion. 相似文献

Oxidative stress is thought to be involved in the pathophysiology of malaria, especially in pregnancy where natural resistance
is markedly reduced. In the present study we investigated oxidative stress in 315 pregnant women out of which 159 had Plasmodium
falciparum malaria and 154 controls. We evaluated the level of lipid peroxidation products (MDA level) in the plasma, the
activity of erythrocyte antioxidant defense enzymes, superoxide dismutase (SOD, EC: 1.15.1.1) and catalase (Cat, EC: 1.11.1.6)
as well as the ability to resist oxidative stress by the FRAP (Ferric Reducing Ability of Plasma) assay. Total erythrocyte
protein levels were also examined. For the two groups of patients, several differences between the biochemical parameters
tested were found. Median parasitaemia in women with malaria was 25,392 parasites/μl of blood (Range1200–82000), while in
controls we had no parasites found in thin and thick smears. Levels of lipid peroxidation products (MDA) were significantly
higher in patients with parasitemia than in healthy asymptomatic volunteers (mean: 0.844 ± 0.290 and 0.384 ± 0.129 respectively,
p<0.001). This MDA level was higher in primigravidea and also correlates well with parasite density (p<0.001). Catalase activity
in erythrocytes of women with malaria did not differ statistically from that of controls. In contrast, SOD activity of patients
with malaria was found to be significantly higher than that of controls (mean: 0.7899 ± 0.2777 and 0.4263 ± 0.2629 respectively,
p<0.05). FRAP values declined, from parasitemic patients (1.4619 ± 0.6565) compare to controls (2.4396 ± 0.8883, p<0.05),
particularly in the first and third trimester of gestation (p<0.05 and p<0.01 respectively). Finally, total erythrocyte protein
concentrations of women with malaria did not differ from that of the controls. Our results suggest an imbalance between oxidants
and antioxidants in pregnant women suffering from malaria, a situation which could lead to severe damage for either the mother
or the fetus. Therefore, further research should be done to assess the potential benefits of antioxidant supplementation for
the pregnant women suffering from malaria. 相似文献

Purpose: Acute benefits of aerobic exercise on executive functioning have been reported frequently under laboratory conditions. However, to date, a beneficial effect on long-term memory has been less well supported and no data are available regarding nonlaboratory conditions in young adults. The aim of the current study was to investigate acute effects of aerobic exercise on cognitive functioning in a university classroom setting. Method: Using a cross-over design, 51 participants performed a bout of moderately intense running (RUN) and read an article while seated (CON). Afterwards, they completed free-recall tests, followed by a Flanker task and an n-back task. Results: Participants in the RUN condition compared with those in the CON condition showed shorter reaction time on the inhibition task, F(1, 50) = 5.59, p = .022, η2 = .101, and recalled more words in the immediate- and delayed-recall tests, F(1, 50) = 8.40, p = .006, η2 = .144. Conclusion: The present findings suggest that a moderately intense bout of aerobic exercise benefits verbal short-term and long-term memory as well as inhibitory control among students in a classroom setting. 相似文献

This paper presents an analysis of the learning outcomes pertaining to one unit of the undergraduate television distance education course Information Technology. This is a course from the undergraduate programme of computer science of Université Laval. The television distance education course was designed to permit students to interact with dynamic environments that support active learning. 相似文献

This article introduces the Diagnostic Profiles (DP) standard setting method for setting a performance standard on a test developed from a cognitive diagnostic model (CDM), the outcome of which is a profile of mastered and not‐mastered skills or attributes rather than a single test score. In the DP method, the key judgment task for panelists is a decision on whether or not individual cognitive skill profiles meet the performance standard. A randomized experiment was carried out in which secondary mathematics teachers were randomly assigned to either the DP method or the modified Angoff method. The standard setting methods were applied to a test of student readiness to enter high school algebra (Algebra I). While the DP profile judgments were perceived to be more difficult than the Angoff item judgments, there was a high degree of agreement among the panelists for most of the profiles. In order to compare the methods, cut scores were generated from the DP method. The results of the DP group were comparable to the Angoff group, with less cut score variability in the DP group. The DP method shows promise for testing situations in which diagnostic information is needed about examinees and where that information needs to be linked to a performance standard. 相似文献

This paper presents a prospective study aimed at identifying the predictors of academic achievement among first-year university students. It tries to develop an inclusive view of academic achievement by taking into account the possible differential impact of several predictors in two different faculties of the university. Some 317 university students from the two faculties (science and physical education), who were in their first year at university, participated in the study. During the academic year, these students completed a questionnaire. The outcome variable was their average academic mark at the end of the year. Multiple regression analyses were performed to identify the most powerful predictors of achievement. The results showed that past school failure, parental education and self-efficacy beliefs predicted achievement in both programs. Age, secondary-school specialisation, reasons for choosing the program, deep processing, time spent studying and intention to persist have also been highlighted as significant predictors of success, but only in one of the two faculties. Self-efficacy was the most powerful predictor of achievement in physical education courses, whereas intention to persist was the most powerful predictor in science. These results show the importance of adopting an integrated and contextualised approach to exploring the predictors of academic achievement at university. 相似文献
