The problem studied in this paper is related to the bienergy of a pull-back vector field from a Riemannian manifold

'n Keuringsbattery vir swart en kleurling naaimasjienoperatrises

The place of selection tests comprising work samples is discussed briefly. Situations in industry where this selection approach is applicable and those in which general psychological tests are sufficient are not always distinguished properly. An example of a situation in which work simulation is warranted for selection purposes, is the case of the sewing machine operator. A battery including machine tests constructed for this selection task is described. Results of validation studies conducted with Black and Coloured applicants are given. Opsomming Die moontlikhede en plek van keuringstoetse wat uit werksmonsters bestaan word kortliks bespreek. Bedryfsituasies waar hierdie tipe tegniek oorweeg behoort te word en gevalle waarin algemene sielkundige toetsing voldoende is, word nie altyd onderskei nie. 'n voorbeeld van waar die werksimulasie geregverdig is, is die keuring van die naaimasjienoperateur of -operatrise. 'n Battery van masjientoetse wat vir hierdie doel opgestel, is, word beskryf en resultate behaal in geldigheidsondersoeke by swartmense en kleurlinge word gerapporteer

Periodic Acid Schiff-Diastase as a key in Exfoliative cytology in diabetics: A pilot study

BACKGROUND: Diabetes mellitus is the fifth most common chronic condition and the sixth most frequent cause of death among the elderly. The objective of this research was to develop a new method for diabetes diagnosis by analysis of the glycogen content of the oral epithelial cells. MATERIALS AND METHODS: Ten control subjects and ten diabetic patients (study group) were taken, four oral smears for both control and study group from the buccal mucosa were taken and stained with hematoxylin and eosin stain, Papanicolaou (PAP) stain, periodic acid Schiff (PAS) stain and PAS-Diastase (PAS-D) stain. RESULTS: The results showed that in the diabetic group: (i) The epithelial cells stained with PAP stain exhibited figures of binucleation and occasional karyorrhexis, (ii) the epithelial cells treated with PAS-D showed that glycogen containing cells did not take up the stain as compared to the other cells. CONCLUSION: The results associated with clinical and histological observations suggest that diabetes mellitus can produce alterations of oral epithelial cells as well as in their glycogen content

A multivariate comparative analysis of industrial arts college students' personality traits

Typescript (photocopy).The purpose of this study was to differentiate personality characteristics of students at Montclair State College; and, to identify those characteristics common to Industrial Arts majors and compare these to the identifiable traits of other majors. To accomplish this, two null hypotheses were proposed and tested using multiple analysis of variance (MANOVA) and discriminant analysis. The sample consisted of a total of 111 full-time students enrolled at Montclair State College representing four groups: Industrial Arts, Business, Fine Arts and Liberal Arts. Industrial Arts (IA) was used as an intact population, whereas the others were selected using stratified randomization techniques. Analyses of the data led to the failure to reject the hypothesis that there is no difference among the personality traits of IA majors at different levels (freshman-senior) of study. Therefore, based on this study, it was concluded the IA group is considered a homogenous group possessing similar personality characteristics in all four levels of study. The data comparing all four groups led to rejection of the hypothesis that there is no difference among the personality traits of students in different majors. As a result, it was concluded that students in different majors at Montclair State College possess discernible personality traits based on the results of this study. Discriminate analyses performed on the four groups indicated the ability of the JPI to distinguish members of each group with relatively high probabilities. This finding indicates the potential usefulness of the JPI as a means to aid guidance counselors and advisors in assisting students to choose a major based on results of the JPI. The ancillary analyses revealed several descriptive characteristics of IA students and how they compared to Jackson's national norms of college students
