    Notes: Summary Although plasma insulin and triglyceride concentrations are positively correlated in many studies, the relationships between insulin resistance, insulin secretion and hypertriglyceridaemia remain unclear. To study these associations, subjects between the ages of 40 and 64 were randomly selected from a general practice register and invited to attend for a standard oral glucose tolerance test for measurement of insulin, triglyceride and non-esterified fatty acid concentrations. The study comprised 1122 subjects who were not previously known to have diabetes and who completed the test. Using the World Health Organisation criteria, 51 subjects were classified to have non-insulin-dependent diabetes mellitus, 188 had impaired glucose tolerance and 883 subjects had normal glucose tolerance. Triglyceride concentrations in subjects with glucose intolerance were elevated compared to those in control subjects, even after adjustment for age, obesity and gender (p 〈 0.001 for subjects with diabetes and p 〈 0.01 for those with impaired glucose tolerance compared to normal subjects). In separate multiple regression analyses for males and females, the most important determinants of the plasma triglyceride concentration were the area under the non-esterified fatty acid suppression curve (p 〈 0.001 in both genders) and the waist-hip ratio (p 〈 0.001 for men and 〈 0.01 for women). The fasting insulin concentration was independently associated with triglyceride concentration in women only (p 〈 0.01). The most important determinant of the area under the non-esterified fatty acid suppression curve in men was the 30-min insulin increment, a measure of insulin secretion, (p 〈 0.001) whereas for women age (p 〈 0.001) and the body mass index (p 〈 0.01) were the most important.

    Aspirations and attitudes of students in chemistry (1979)

    Notes: Abstract The attitudes of Belgian chemistry students, who had chosen their specialist study area for their final year of chemistry studies, towards organic chemistry, physical chemistry, inorganic chemistry, biochemistry and analytical chemistry were measured using an instrument based on the Osgood Semantic Differential. Major differences between the attitudes (as a function of specialist field) were found to be in the activity attitudes rather than in the evaluative or potency attitudes. The area of specialisation does not appear to markedly correspond to differences in the students' expectations of their different courses; they expect to acquire the same skills.

    Students who study chemistry: Some affective aspects of undergraduates (1981)
    Springer

    Notes: Abstract First year student expectations of their forthcoming chemistry courses, the degree to which those expectations are realised, and their attitudes towards chemistry at the end of the year were examined by discriminant analysis. A total of 1,438 Students (Ss) drawn from three Belgian universities and taking twelve different major study subjects took part. Degree of satisfaction with the separate components of the chemistry courses, unlike the overall sense of satisfaction, does not seem to be a valid means of discriminating between their differing course needs. The same is true of their expectations. Any rejection of the development of abstract thinking in universities was found not to be the result of experience prior to university entrance. Attitudes towards chemistry alone also cannot be used as a means of discriminating between populations, although attitudes do correlate with the concordance between expectations and realisations. Evidence was also found supporting earlier work of others that negative attitudes toward science (in this case chemistry) are generated by pitching courses at too great a level of difficulty. Overlap of population interests indicates that the chemistry course needs of the students (Ss) could be met by four separate courses.

    Chemistry degree curricula — undergraduate feelings (1983)

    Notes: Abstract The end-of-first year attitudes towards chemistry, the degree to which course expectations matched realisations, and examination scores were available for 110 Belgian freshman chemistry majors. Four years later, data of subsequent “careers” enabled the students (Ss) to be classified in four groups: those who continued as chemistry majors throughout their university studies; those who changed their major study but stayed at university; those who left university for non-university higher education; and those who ceased their studies. Using discriminant analysis it was possible to predict approximately 70% of those destined to form Group 1. The prediction of those in the other groups became progressively weaker. The difference between groups is discussed in terms of the discriminating variables. Measures of the attitudes of the students towards chemistry four years later revealed that these later feelings could not be predicted on the basis of their feelings at the end of their first year of studies.
