LOOKING INSIDE VOTIVE CREATURES: COMPUTED TOMOGRAPHY (CT) SCANNING OF ANCIENT EGYPTIAN MUMMIFIED ANIMALS IN IZIKO MUSEUMS OF SOUTH AFRICA: A PRELIMINARY REPORT

The ancient Egyptians mummified many more animals than humans. The study of ancient Egyptian animal mummies is varied and extensive. Currently new methodologies and modern technology are being used to unlock the secrets of animal mummies. Recently five animal mummies housed in the Egyptian collection of Iziko Museums of South Africa in Cape Town were scanned using a state of the art computed tomography (CT) scanner at Stellenbosch University. Preliminary results revealed two complete bird skeletons, a claw, a fake and the partial skeleton of what appears to be a cat

A Focused Analysis of Recruitment and Performance Management in the Import and Export Industry

While many studies have been conducted on recruitment and performance management, there is a paucity of research on these two functions within the industry. Recruitment and performance management are vital human capital and human resource (HR) functions that play a crucial role in guaranteeing an organisation’s ability to achieve its business strategy. Furthermore, studies have shown that in recent years, performance management has become intrinsic to most organisations. The research comprised five phases of data collection from 151 randomly selected respondents. A questionnaire was developed and distributed to gain insight into how these two functions were executed within the industry under investigation. Thereafter a performance management module was developed and implemented, and the questionnaire was redistributed after six months. The results support the view that the functions of recruitment and performance management are poorly managed within the industry. Furthermore, the intervention of the performance management module indicates that interaction with employees relating to individual performance enhances both their work performance and general awareness of inter-personal and organisational issues. The findings from this research suggest that recruitment and performance management are essential HR practices often overlooked in an environment that is extremely demanding. Disregard of these practices, especially performance management, has proved to have a negative impact on employee job performance. It is therefore recommended that organisations follow processes and invest in such programmes, not only to achieve their organisational goals, but also to develop and enhance employee performance. This study has specific and important implications for the import and export industry, substantiating the researcher’s premise that effective recruitment and performance management can improve and facilitate the management of the industry’s employees

The ethicolegal framework relevant to human faecal microbiota transplants in South Africa: Part 2. Human stool as tissue?

Faecal microbiota transplantation (FMT) has been shown to be an effective treatment for recurrent Clostridioides difficile infection. The purpose of this article, the second of a series of three articles, is to explore the legal framework governing human FMT in South Africa (SA). FMT involves different modes of administration that require different regulatory considerations. The focus of this article is to explore the legal classification of human stool as tissue in terms of the National Health Act 61 of 2003, as well as the regulation of human stool banks as tissue banks. The article concludes with specific recommendations aimed at improving the current regulatory vacuum relating to the regulation of FMT in SA

The ethicolegal framework relevant to human faecal microbiota transplants in South Africa: Part 1. A legal vacuum

The legal regulation of faecal microbiota transplantation (FMT) in South Africa (SA) is currently unclear. The purpose of this article, the first of three in a series, is to explore the nature, role and clinical application of FMT in SA in order to determine, from a legal perspective, the appropriate regulatory pathways governing FMT as a procedure that may combine approaches for the treatment of drugs, human tissue for transplantation, or clinical treatment as part of the practice of medicine. FMT has been shown to be a novel, safe and effective treatment for recurrent Clostridioides difficile infection (CDI). Stool banks are instrumental in enabling access to FMT for patients and clinicians and help to catalyse research in the microbiome. However, the regulatory landscape in SA remains unclear. Microbial therapies such as FMT are necessary, especially in a time of rising microbiome-associated inflammatory diseases and increasing resistance to traditional antibiotics. FMT is now considered as part of the standard of care for recurrent CDI overseas, but is currently only being used for research purposes in a minority of clinical cases of CDI in SA. This article, which lays the foundation for consideration of this question in three parts, suggests that the relevant regulatory system would depend on the categorisation of human stool as tissue, the exact composition of the FMT, how it is administered to patients, and the relevant levels of manipulation of the stool for FMT-derived products

Chromosomal radiosensitivity of lymphocytes in South African breast cancer patients of different ethnicity: An indirect measure of cancer susceptibility

Background. Breast cancer is the leading cancer among South African (SA) women. SA has citizens from diverse ethnic groups, and the lifetime risk of breast cancer differs according to ethnicity. Candidate genes for increased breast cancer risk are those involved in DNA damage repair pathways, and mutations in these genes are characterised by increased chromosomal radiosensitivity. Several European studies have shown that breast cancer patients are more sensitive to ionising radiation than healthy individuals.Objectives. To investigate the in vitro chromosomal radiosensitivity of SA women with breast cancer and the possible influence of ethnicity and clinical parameters on chromosomal radiosensitivity.Methods. Chromosomal radiosensitivity was analysed with the micronucleus assay using lymphocytes of breast cancer patients and healthy individuals of different ethnic groups. Lymphocytes were irradiated in vitro with 2 Gy or 4 Gy, and micronuclei (MN) were scored 70 hours after irradiation. These MN frequencies were correlated with the ethnicity and clinical parameters of the breast cancer patients.Results. MN values were higher in breast cancer patients than in healthy controls. This was noted for black and white breast cancer patients at the different radiation doses. No correlations could be demonstrated between MN values and clinical parameters of the breast cancer, except that MN values were significantly higher in oestrogen receptor (ER)-positive breast cancers.Conclusion. SA breast cancer patients have elevated chromosomal radiosensitivity compared with healthy controls. ER positivity also influences chromosomal radiosensitivity

Assessing distress tolerance using a modified version of the Emotional Image Tolerance task

The Emotional Image Tolerance (EIT) task assesses tolerance of negative emotion induced by negatively valenced images. We made several minor modifications to the task (Study 1) and adapted the task to include positive and neutral images in order to assess whether individuals respond to the valence or the intensity of the image content (Study 2). In both studies, we assessed subjective distress, gender differences in task responses, and associations between behavioral and self-reported distress tolerance, and related constructs. Across both studies, the EIT successfully induced distress and gender differences were observed, with females generally indicating more distress than males. In Study 2, responses on the adapted EIT task were correlated with self-reported distress tolerance, rumination, and emotion reactivity. The EIT successfully induces distress and the correlations in Study 2 provide promising evidence of validity

Measurement invariance of the distress tolerance scale among university students with and without a history of non-suicidal self-injury

Non-suicidal self-injury (NSSI) is the intentional damage to one's body tissue in the absence of suicidal intent. NSSI primarily serves an emotion regulation function, with individuals engaging in self-injury to escape intense or unwanted emotion. Low distress tolerance has been identified as a mechanism that underlies self-injury, and is commonly assessed using the self-report Distress Tolerance Scale. There are mixed findings regarding the factor structure of the Distress Tolerance Scale, with some researchers utilising a higher-order distress tolerance score (derived from the scores on the four lower-order subscales) and other researchers using the four subscales as unique predictors of psychological outcomes. Neither of these factor structures have been assessed among individuals with a history of self-injury. Of note, an inability to tolerate distress (thought to underlie NSSI) may limit an individual's capacity to accurately observe and report specific thoughts and emotions experienced in a state of heightened distress, which may impact the validity of scores on the Distress Tolerance Scale. Therefore, measurement invariance should be established before attributing NSSI-related differences on the scale to true differences in distress tolerance. We compared the Distress Tolerance Scale higher-order model with the lower-order four factor model among university students with and without a history of NSSI. Our results indicated that the lower-order four factor model was a significantly better fit to the data than the higher-order model. We then tested the measurement invariance of this lower-order factor model among individuals with and without a history of NSSI, and established configural and full metric invariance, followed by partial scalar and full residual error invariance. These results suggest the four subscales of the Distress Tolerance Scale can be used to confidently discern NSSI-related differences in distress tolerance

African leafy vegetables in South Africa

In this article the term ‘African leafy vegetables’ was adopted to refer to the collective of plant species which are used as leafy vegetables and which are referred to as morogo or imifino by African people in South Africa. Function is central in this indigenous concept, which is subject to spatial and temporal variability in terms of plant species that are included as a result of diversity in ecology, culinary repertoire and change over time. As a result, the concept embraces indigenous, indigenised and recently introduced leafy vegetable species but this article is concerned mainly with the indigenous and indigenisedspecies. In South Africa, the collection of these two types of leafy vegetables from the wild, or from cultivated fields where some of them grow as weeds, has a long history that has been intimately linked to women and their traditional livelihood tasks. Among poor people in remote rural areas the use of these types of leafy vegetables is still common but nationwide there is evidence of decline, particularly in urban areas. Cultivation of indigenous or indigenised leafy vegetables is restricted to a narrow group of primarily indigenised species in South Africa. Seven groups of indigenous or indigenised African leafyvegetables that are important in South Africa were given special attention and their local nomenclature, ecology, use and cultivation are discussed

Concern level assessment: building domain knowledge into a visual system to support network-security situation awareness

Information officers and network administrators require tools to help them achieve situation awareness about potential network threats. We describe a response to mini-challenge 1 of the 2012 IEEE VAST challenge in which we developed a visual analytic solution to a network security situation awareness problem. To support conceptual design, we conducted a series of knowledge elicitation sessions with domain experts. These provided an understanding of the information they needed to make situation awareness judgements as well as a characterisation of those judgements in the form of production rules which define a parameter we called the ‘Concern Level Assessment’ (CLA). The CLA was used to provide heuristic guidance within a visual analytic system called MSIEVE. An analysis of VAST challenge assessment sessions using M-SIEVE provides some evidence that intelligent heuristics like this can provide useful guidance without unduly dominating interaction and understanding
