- Description: The risk of civilians being exposed to a traumatic event in South Africa is relatively high. This also means that several professional helpers termed first responders, will have frequent contact with individuals who have been traumatized. Working with trauma survivors could have both negative and positive outcomes. On the one hand, first responders’ interaction with trauma survivors provide them with the opportunity to detect when a survivor may be at risk of developing posttraumatic stress disorder (PTSD). Unfortunately, this exposure also puts them at risk of developing secondary traumatic stress with symptoms like those of the trauma survivors they assist. Secondary Traumatic Stress (STS) is relatively well studied among certain helping professions such as therapists, counsellors, social workers and even advocates who work with trauma survivors. Research concerning STS among emergency unit first responders is, however, limited (especially in the South African context). Furthermore, literature investigating emergency unit first responder’s perception of secondary traumatic stress and the screening and referral of trauma survivors at risk of developing PTSD in a South African context appears to be non- existent. The current study aimed to explore and describe first responders’ perceptions of STS and the screening and referral of trauma survivors at risk of developing PTSD. A qualitative design was employed using semi-structured interview questions. The researcher employed a purposive sampling method. As such, only first responders in the emergency unit of general hospitals who regularly work with trauma survivors will be considered for the current study. The data from the interviews was analyzed using thematic analysis based on the principles proposed by Braun and Clark (2006). The findings from this study indicated that while first responders are at risk of developing STS due to the high frequency exposure to traumatic material, very few considered the effects of working with trauma on their mental health. Furthermore, participants in this study reported having inadequate knowledge of PTSD and did not feel confident in screening for trauma survivors at risk of developing PTSD. In addition, participants reported that, while they have previously screened and referred trauma survivors who may be at risk, there was no standard protocol for screening and referring such patients. That being said, the participants did state that should they consider a patient a risk, the hospitals in which they worked did have psychologists on-site.

- Description: Organisational leaders often assume that change (large or small) is straightforward and the approach to solve the problems is done rationally and logically. Thereafter a strategy is developed and a plan is implemented to make the improvement a reality. It comes as a shock to organisational leadership that those improvement plans, initially envisioned, do not deliver on expectations. As mentioned in The effective change managers’ handbook (Smith, et al., 2014), a greater shock awaits organisational leadership that after convincing colleagues of the necessity for the change to solution and the need to resolve the issue, in reality, it does not always work or achieve the desired outcomes. Improvement plans are often met with resistance by various stakeholders within the organisation. As a result, these improvement plans are abandoned and the organisation is relegated to business as usual. Literature reviewed in the field of organisational change management reveals a failure rate of 70% to 80% when it comes to the implementation of change initiatives and more so where change initiatives have a low expected return on value. Organisational change and organisational change management literature is constantly evolving as variable criteria and measures are researched, revealing deeper insight and impact on organisations. Therefore, according to literature, a greater knowledge of organisational change management within a global context would provide relevance and richness in the manner in which organisations go about implementing change initiatives. The key challenges and management issue at hand are to explore, understand and comprehend the variables that influence the branch manager’s positive reaction to change. This will guide organisational leadership and improve the success rate of change initiatives implemented in the organisation.For Absa to maintain a competitive advantage and ensure sustainability, a comprehensive understanding of the variables that influence the branch managers’ positive reaction to change is an imperative for Absa’s organisational leadership. Organisational change and organisational change management have all the key elements for the implementation of change within organisations. If executed effectively, this would result in a positive reaction by employees when change initiatives are introduced into the organisation. By studying past experiences and outcomes from empirical studies on organisational change and organisational change management, it was possible to draw lessons and experience about the discipline of organisational change management and factors influencing effective implementation of change initiatives resulting in a greater degree of success. The study may be of significance to other organisations across industries looking at improving the success rate in terms of implementing change initiatives within the managerial level of an organisation. Factors that come to the fore are creativity in influencing leadership behaviour, due diligence about investment opportunities, return on change initiatives, etc. These need to be explored in order for the organisation to achieve the objectives of remaining competitive and ensuring the sustainability of the organisation. Therefore creative strategies and thinking of ways to circumvent challenges in organisational change and organisational change management needs to be employed. The following independent variables were tested: training, effective communication, employee inclusion, trust, decreasing fear of the unknown and finally, decreasing fear of failure. Results revealed from the quantitative research that trust and decreasing fear of the unknown are essential factors influencing branch managers’ positive reaction to change though the importance of the other independent variables tested must not be considered to be of lesser importance. This study therefore concluded that utilisation of the framework, with emphasis on trust and decreasing fear of the unknown will result in the positive reaction by Absa branch managers to change and this will ultimately influence the success rate of change initiatives implemented. Recommendations were also made for future research studies that can contribute to organisational change and change management literature with emphasis on positive reaction to change, as well as the improvement and success rate of change initiatives implemented within organisations.

- Description: The aim of the project was to develop a small production platform for citronellal processing. The objective of the study was to develop a single continuous flow reactor system for the synthesis of novel derivatives of citronellal and isopulegol. The first step was to develop a continuous flow reactor system for the isopulegol synthesis. The stainless steel tubular fixed-bed reactor equipped with a reaction column (I.D: 9.53 mm and length: 120 mm) was used for the study. The reactor column was packed with H-ZMS-5 zeolite extrusion catalyst. The solvent-free cyclisation reaction of citronellal was investigated and at optimum conditions, 100% of citronellal conversion and almost 100% selectivity towards isopulegol was achieved. A good catalytic performance was observed from the H-ZSM-5 catalyst and proved to be stable for a prolonged reaction time. The second reaction step was to develop a continuous flow reactor system for the synthesis of isopulegyl-ether derivatives. A UniQsis FlowSyn reactor system equipped with a stainless steel reactor column was used for the study. The reactor column was packed with amberlyst-15 dry catalyst. Wherein, n-propanol was employed as a model etherifying agent and as a reaction solvent. At optimum reaction condition, only 30% selectivity of isopulegyl propoxy-ether was achieved. The reaction was found to depend highly on temperature and residence time. The increase of these parameters was found to increase the side reactions and reduced the selectivity of the desired product. Other heterogeneous catalysts such as H-beta zeolite, aluminium pillared clay, Aluminium oxide and H-ZSM-5 were also evaluated in the reaction. Among these catalysts, a catalytic activity was observed with H-beta zeolite (19%) and aluminium pillared clay (5%). Based on these results, none of the evaluated catalysts provided the desired selectivity (greater than 70%) towards the isopulegyl propoxy-ether, therefore the process was not investigated further. In light of this, the isopulegol etherification synthetic route was terminated. Consequently, another analogue of citronellal was used as an alternative intermediate in place of isopulegol, namely para-menthane-3,8-diol (PMD). The initial studies for the synthesis of the novel PMD di-esters from isopulegol were performed in the batch-scale reactor. In a solvent-free reaction, acetic anhydride was initially used as a model acetylating agent. The reaction was performed using polymer-bound scandium triflate (PS-Sc(OTf)3) catalyst. The effect of reaction parameters such as temperature, molar ratio, and reaction time were studied towards the PMD conversion and di-esters selectivity. At optimum reaction conditions, PMD conversion of 70% and di-acetate selectivity of 67% were observed. The reaction was found to follow the zeroth-order kinetics with respect to PMD conversion and obeyed the Arrhenius equation. Other types of di-ester derivatives were synthesized from PMD by varying the carbon chain length of the acetylating agent. The prepared compounds were separated from the product mixtures by vacuum distillation, purified on a column chromatography and characterised by FT-IR, GC-MS, and 1H-NMR, 13C-NMR. The developed methodology was optimised in flow by using an ArrheniumOne microwave-assisted continuous-flow fixed-bed reactor system. A detailed experimental design was used to carry-out the reactions. The reaction parameters such as temperature and flow-rate were studied towards the PMD conversion and di-ester selectivity. From the experimental design analysis, the di-ester selectivity was found to depend highly on the residence time (flow-rate) and significantly on temperature. The PMD conversion and di-ester selectivity were found to increase with decrease in the flow-rate. The conversion and selectivity achieved in the continuous flow process were significantly higher than the achieved in the batch-scale process with respect to the residence time.
