Orientation: A growing movement of foreign nationals is settling in South Africa. Given this, there is a need to understand not only those factors influencing foreign nationals to settle in South Africa but also their lived experiences as a basis for individual career development.Research purpose: To investigate the expatriation motivational factors and experiences of selfinitiated academic expatriates in South Africa.Motivation for the study: Calls have been made within the careers literature for more empirical focus on understanding career development using some of the neglected sample groups.Research approach, design and method: The interpretive paradigm was adopted to understand the main purpose of the study. Guided by study objectives, unstructured interviews were conducted using a sample of foreign academics working in South Africa (n = 25).Main findings: Individual stories and narratives highlighted that academics relocated for the following reasons: (1) individual preference, (2) economic meltdown and (3) political conditions. Furthermore, the lived experiences of the expatriates reflected discrimination within the workplace and the community of residences in South Africa.Practical and managerial implications: Research findings indicate that the human resources (HR) function can come up with interventions that positively influence the lived experience and career development of foreign academics working in South Africa.Contribution: The expatriate experience framed in this study provides a picture of the career development processes of neglected sample groups in the extant literature. Such an understanding is key in advancing literature and proposing interventions. All this is important given the global trend on labour and skills movement added to the role South Africa plays in the international arena.

Previous studies of chronic dermatoses have suggested that expression of the CD54 cell surface antigen (intercellular adhesion molecule-1, ICAM-1) by keratinocytes is a feature of chronic inflammation. However, whether such expression is a prerequisite for intraepithelial migration of lymphocytes is unclear. The present study evaluated the expression of CD54 and its ligand, CD11a (lymphocyte function-associated antigen, LFA-1) in oral lesions of lichen planus, recurrent aphthous stomatitis, secondary Sjögren's syndrome and traumatic ulceration using an immunoperoxide technique. In 33 of 56 lesions examined, substantial numbers of CD11a + cells were present within oral mucosal epithelium despite an absence of detectable keratinocyte CD54 antigen expression. Consequently, CD54/CD11a adhesion interactions may not be critical in the initiation of oral mucosal inflammation.

Orientation: Details of applicants’ secondary education (incorporating subject choice) could be a useful screening tool when processing large applicant pools. Here, the relationships between secondary education (incorporating subject choice) and the reasoning and visual perceptual speed components of the Differential Aptitude Test are explored.Research purpose: The objective of the study was to determine whether type of secondary education (incorporating subject choice) could be used as a substitute for reasoning (verbal and non-verbal) and/or visual perceptual speed aptitudes in the selection of operators for an automotive plant in South Africa.Motivation for the study: The motivation for this study arose from the evident gap in academic literature as well as the selection needs of the automotive industry.Research design, approach and method: This research adopted a quantitative approach. It involved a non-probability convenience quota sample of 2463 work-seeking applicants for an automotive operator position in South Africa. Participants completed a biographical questionnaire and three subtests from the Differential Aptitude Test battery. The Chi-square test was used to determine the relationship between type of secondary education (incorporating subject choice) and selected cognitive aptitudes.Main findings: The study’s findings revealed statistically and practically significant relationships between type of secondary education (incorporating subject choice), verbal reasoning, non-verbal reasoning and visual perceptual speed. Broad performance levels in the three aptitude subtests employed in this study were significantly associated with the type of matriculation certificate held by applicants. The findings specifically indicated that the secondary education types that included the subjects mathematics or both mathematics and science were associated with higher levels of performance in the three aptitudes. This had consequences for these applicants’ success in the screening process which could lead to enhanced chances of employability.Practical and managerial implications: Applicants’ type of secondary education (incorporating subject choice) could be regarded as a key criterion in human resource selection and be instructive in the screening process. This could reduce the candidate pool prior to more costly psychometric assessments.Contribution or value-add: The findings are specifically relevant to the South African automotive industry in terms of their human resource selection practices. The insights gained from the findings may also be used as a guide to human resource practitioners in the selection of similar level employees in other working contexts. The study makes a case for a multiple-hurdle approach to selection.
