Relationship between Body Dissatisfaction and Eating Disorder of University Students
No full textThis study examined the relationship between body dissatisfaction and eating disorder of undergraduate students in University Malaysia Terengganu (UMT). Using stratified random sampling technique, data from 299 respondents was gathered. Body dissatisfaction was measured using Body Shape Questionnaire while eating disorders were assessed using Eating Attitudes Test. Descriptive statistics showed that the majority of the respondents reported no symptom of body dissatisfaction. With regard to eating disorders, respondents reported low levels of dieting, bulimia and oral control, indicating that an eating disorder in this sample was somewhat low. T-test analyses showed that there were no significant gender differences in body dissatisfaction as well as in eating disorders. However, there was evidence to suggest that female respondents had slightly higher level of eating disorder than males. Results of Pearson correlations showed there was significant relationship between body dissatisfaction and total score of eating disorders, dieting, bulimia and oral control subtypes (r = .58, p <.001; r = .64, p<.001; r = .39, p<.001; r = .18, p<.001; respectively) in that, higher level of body dissatisfaction was significantly related to increased risk of eating disorders
Boosting Students’ Performance with the Aid of Social Network Analysis
No full textThere are various teaching methods developed in order to attain successful delivery of a subject without prior knowledge of the interaction among the students in a class. Social network analysis (SNA) can be used to identify individual, intermediate and group measures of interaction in a classroom. The idea is on identifying ways to boost the students’ performance by means of lecturer’s intervention based on their interaction. The case study was conducted involving third year batch that consisted of 76 female and 24 male students. A friendship network was drawn based on the information obtained at the end of semester 5 and it was investigated based on two metrics – centrality measures and Girvan-Newman algorithm. At the end of semester 5, grades were added as the attributes of the network. 12 clusters were found in this batch and a distinct pattern was identified between performing and poor achieving students. At the beginning of the 6th semester, the students were given the option to choose between 2 groups. Group 1 was unperturbed without any lecturer’s intervention whereas the performing students’ clusters in Group 1 were preserved but the students in poor performing clusters were distributed among performing clusters. The students were then asked to carry out assignments/quizzes in their respective groups. The final grades indicated that the performance of the students of Group 1 was much superior and there was clear evidence that those poor performing students in the 5th semester performed much better in semester 6. This shows that by understanding the students’ interaction and incorporating instructor’s minimal intervention, the performance of the students can be improved by creating a social contagion effect through group assignment clustering
Plant Conservation Status and Species Diversity of Hutan Lipur Jeram Linang, Kelantan
No full textA study to determine plant species diversity and the conservation status of a hilly lowland forest of Hutan Lipur Jeram Linang in Kelantan was carried out within 0.1 ha plot. All vascular plants (except lianas and epiphytes) were enumerated and identified. A total of 255 taxa representing 121 species belonging to 87 genera in 47 families were identified. Among these were 24 species endemic to Peninsular Malaysia and 47 species with medicinal values. Plants were categorized according to growth forms as follows: 67% trees, 17% shrubs, 7% palms, 6% herbs, and 3% ferns. Based on Important value index (IVI), Elateriospermum tapos, Goniothalamus umbrosus, and Monocarpia marginalis were the most dominant species whilst Rubiaceae, Arecaceae and Fabaceae were the three most diverse families. Species diversity was high based on the Shannon-Weiner index with the value of 4.38. In this study, two species from Dipterocarpaceae, which were Dipterocarpus grandiflorus and Shorea collina, were listed as Endangered (E) and Critically Endangered (CE) species respectively according to IUCN Red List. Information gained from this study showed that the forest harbored high plant diversity and endemism, so proper management is needed to protect and conserve this forest for sustainability and development
Stability of Lactic Acid Bacteria in Pasteurized Cow’s and Goat’s Milk
No full textThis study was done to determine the effect of pasteurization on the stability of lactic acid bacteria (LAB) and its enzyme in raw and pasteurized cow’s and goat’s milk. The total viable count for plate count of the bacterial growth concentration was higher in both pasteurized cow’s and goat’s milk at 2.48 log CFU/ml. This is followed by raw cow’s milk (1.59 log CFU/ml) and raw goat’s milk (0.65 log CFU/ml). Lactic acid bacteria (LAB) was found to be similar in both raw cow’s and goat’s milk (p>0.05), and pasteurized milk of both animals also contained the same amount of LAB (p>0.05). LAB was still detected in pasteurized milk (p<0.05), indicating the stability of LAB against the pasteurization temperature. Interestingly, based on API ZYM assay kit results, there were nine different enzymes detected in all samples, which were leucinearylamidase, valinearylamidase,cystinearylamidase, trypsin, α-chymotrypsin, naphthol-AS-BI-phosphohydrolase, α-glucosidase, β-glucosidaseand acid phosphatise. The results revealed that different types of lactic acid bacteria were detected in treated and non-treated milk samples produced by different animals, indicating the different stability levels of LAB against pasteurization
