- Description: The primary purpose of the study is to highlight the social security law position of employees involved in MVAs. The study concludes and notes that: The current social security system provides an inadequate prevention strategy for employees involved in MVAs. A blanket program of fitness for work as an occupational accident prevention tool should be legislated and be part of the OHSA general duties of employers to their employees. A social security system that attempts to address loss of ability to earn as a result of occupational injury must incorporate an integrated approach towards prevention of risks, compensation and rehabilitation. Social security legal instruments currently providing compensation for employees involved in MVAs (RAF and COIDA) are promulgated for more benefits. A RTW plan, Vocational assessment and rehabilitation of injured employees, all processes that will aid continued employment for injured employees, will be included. This will ensure that employees continue to earn income which forms the basis of social security.

- Description: The perceptions of Nelson Mandela Metropolitan Municipality obstetric unit midwives regarding consulting advanced midwives were researched. Currently South Africa is burdened with an increasing maternal mortality rate despite the control measures that have been put in place. One of those control measures is the skilling of midwives and ensuring that skilled birth attendants assist every woman in confinement. A concern, though, was observed by the researcher that an increasing number of midwives in the country now have an additional qualification in advanced midwifery and yet the maternal and neonatal mortality rates are gradually increasing. The researcher, as a midwife and a midwifery lecturer in that capacity, observed that in the clinical areas midwives prefer to consult with the doctor rather than the advanced midwife. In most cases looking and waiting for the doctor delays the management of the labouring woman as the doctor may not be immediately available. The advanced midwives are supposed to have advanced skills which should be used to assist in the absence of the doctor, particularly in the midwife obstetrics units. The study objectives were firstly, to describe and explore the perceptions of NMM obstetric unit midwives regarding consulting with advanced midwives. Secondly, based on the results of the study, to make recommendations to the managers of the obstetric units within the NMM that will enhance consulting between advanced midwives and midwives in obstetric units. The study was quantitative in nature and utilised an explorative, descriptive and contextual design. Sampling was made possible through simple random probability sampling using the non-replacement approach. The method of data collection was by self-administered questionnaires that were developed by the researcher under the guidance of a qualified and experienced statistician and researcher and the supervision of the research supervisor. Data was collected during July and September of 2014. One hundred and thirty questionnaires were distributed and ninety four were returned. Responses were captured on a spread sheet for easy and accurate calculation and the numerical data was categorized, ordered and manipulated with the help of a statistician using the software package Statistica Version 21 to ensure efficacy of the results The findings were presented by describing the biographic profile of participants, their competence in the identification and management of high risk situations, their consultation with advanced midwives in high risk situations, their reasons for not consulting advanced midwives and a description of factors that might encourage midwives to consult the advanced midwives. Literature controls were utilized to compare findings with current views of other researchers. Trustworthiness was maintained by observing the principles of reliability and validity. The ethical considerations of confidentiality, anonymity and protection of the participants from harm were maintained by the researcher. The findings revealed that there were significant numbers of midwives with many years of clinical experience and years in the units. The age difference of the midwives in the obstetrics units was seen to be an added advantage to the care of women as the young and old could complement each other with the latest information and experience in dealing with midwifery related emergencies respectively. The difference in gender was as expected but did not have an influence on the non-consulting with advanced midwives by the midwives who are working in the obstetrics units. Also, the limited confidence of midwives regarding their performance of certain low risk skills and their confidence in the performance of the advanced midwives was a reason to consult with the advanced midwives in their areas of speciality. Based on these findings, the researcher attended to the second objective and made the necessary recommendations to the managers of the obstetric units within the NMM to enhance consulting with advanced midwives by midwives in obstetric units. Midwives globally would gain information that would assist them in motivating recommendations to the managers of the obstetric units with regard to consulting with advanced midwives by midwives in their obstetric units.

- Description: Torpor and hibernation, two distinct forms of heterothermy, are physiological responses employed by many endotherms to save energy during periods of cold, climatic unpredictability and food shortage. Heterothermy is characterized by varying body temperature and has been found to occur in various subtropical mammals. However, studies on thermoregulatory capabilities of South African Microchiroptera remain relatively scant. In this study, the capacity for use of heterothermy, the seasonal metabolic rates, and capacity for non-shivering thermogenesis were studied in four species of bats, namely Rhinolophus clivosus, Rhinolophus capensis, Miniopterus natalensis and Myotis tricolor. Animals were collected from a group of three mines in Sleepy Hollow Farm, 30km from Port Elizabeth, South Africa. All species demonstrated bouts of torpor in the winter while R. clivosus interestingly established a high propensity for torpor in the summer and normothermia in the winter. To my knowledge, this is the first study that has shown the down-regulation of metabolism and body temperature in summer and constant maintenance of normothermic body temperature in winter in a species of Microchiroptera. M. natalensis was thermolabile in both summer and winter and body temperatures closely tracked ambient temperatures. Mean ± SD normothermic body temperature measured of wild-caught R. clivosus and M. natalensis was 38.6 ± 1.7°C and 37.3 ± 2.2°C, respectively. Mean torpid body temperature measured of wild-caught R. clivosus, R. capensis and M. natalensis was 22.7 ± 3.3°C, 21.1 ± 3.2 °C, and 22.6 ± 3.1°C, respectively. Non-shivering thermogenesis was measured in R. clivosus and M. natalensis to determine the role of endogenous heat production in a volant mammal. The mean noradrenalineinduced thermogenesis ± SD in R. clivosus and M. natalensis was 2.6 ± 0.8 ml g-1 hr-1 and 2.7 ± 0.6 ml O2 g-1 hr-1, respectively. Both species demonstrated capacity for non-shivering thermogenesis, and this is the first study that has quantified the maximal response to noradrenaline in an Afrotropical Microchiropteran species. Physiology of Afrotropical bats is understudied and the extent to which torpor and/or hibernation is utilized amongst them remains relatively unknown. Heterothermy clearly plays a significant role in the energetic savings and balance of all four species in the study.
