- Description: The purpose of this study was to identify factors that impact on staff turnover and strategies that organisations can use to curtail staff turnover. To achieve this goal the following procedure was followed. An overview of theories related to staff turnover was conducted to identify what staff turnover is. Also the consequences of staff turnover, the classification and measurement of staff turnover and the broad theoretical explanation of staff turnover were investigated. The current brain drain experienced in the medical field was explored. A literature study was also conducted focusing on individual, job, organisational and environmental factors that influence staff turnover and strategies that managers can utilise to reduce staff turnover. Interviews were conducted with the chief executive officer and one doctor at Hewu hospital. Interviews were also conducted among senior nurses. An empirical study was undertaken to determine individual, job, organisational and environmental factors that impacted on staff turnover among doctors and nurses at Bisho and Hewu Hospitals. The strategies that were utilised at these hospitals to retain doctors and nurses were also investigated. Suggestions were made for addressing factors that could impact on staff turnover among doctors and nurses and strategies that could be utilised to retain staff. These strategies include: Getting people off to a good start, Create a great environment with bosses whom people respect, Share information, Give people as much autonomy as they can handle and Challenge people to stretch. iii Staff turnover is an issue that many South African organisations are currently facing and an issue that is especially affecting the medical field. Various factors, especially job and organisational factors, are not adequately addressed and these could lead to a high rate of staff turnover. It is clear that organisations should have a human resource strategic plan in order for them to effectively select, retain, train and develop employees. Health Care organisation could use the strategies identified in this study as a mechanism to benchmark how well they manage staff turnover. It is therefore important that the management of hospitals should strive to identify the underlying causes of labour turnover in their organisations and formulate strategies to address the problem.

- Description: Weather has a significant impact on business activities of many kinds. The list of economic activities subjected to the risk of the weather include: the energy producers and consumers, the industry of leisure, the insurance industry, the food industry and the agricultural industries but the primary industry, namely the energy industry, has given rise to the demand for weather derivatives and has caused the weather risk management industry to evolve actively. A derivative is a contract or security, whose payoffs depend upon the price of an underlying asset price, and is used to control the risks of naturally-arising exposures to such an asset price. Therefore weather derivatives are financial contracts with payouts that depend on weather in some form. It is a contract that provides a payoff in response to an index level based on weather phenomena (West, 2002).The underlying variable can be for example humidity, rain, snowfall, temperature, or even sunshine. The main players who take part in the weather derivatives markets industry can be grouped in to five main categories, namely: 1) End users who are also referred to as hedgers 2) Speculators 3) Market makers 4) Brokers 5) Insurance and re-insurance companies. Since the late 90’s when the first weather derivatives transactions were recorded, the underlying market has witnessed the development of a new derivative market in the United States, which is gradually expanding across Europe. However, the newly developed market for weather derivatives is not liquid in Africa and specifically South Africa mainly due to the following factors: 1) Many companies and business organisations have not yet established a hedging policy or even figured out how their businesses or industries are exposed to weather risks. 2 2) “Since many companies and industries depend on insurance companies to cover their risks, it is possible that the solutions suggested by these companies or industries looking for protection from weather risks differ according to the cover provided by these insurance organisations “(Micali, 2008). The main aim of this study is to review available statistical models for pricing derivatives, with temperature as the underlying which could enable industries, businesses and other organisations in South Africa to protect themselves against losses due to fluctuations in the weather and therefore hedge their risks.

- Description: This study investigates the relationship of bank customers’ behavioural patterns based on the customers past transactions, with respect to their profile characteristics. The main aim of this study is to illustrate that different categories of customers (based on demographical variables such as race, gender and age) have statistically significant differences in behaviour, with respect to how they operate their accounts. A theoretical overview on the literature of customer relationship management in the banking sector emphasises the importance of understanding customers to ensure that a business is successful. Four null-hypotheses where formulated based on a general research hypothesis. The data base provided a major South African bank is used to achieve the objectives. Extensive cleaning of the data set was necessary to ensure the validity of the results. The data set had 7860 customer keys. The large data base used contributed to the reliability of the results. The following behavioural variables were used in the study namely, transaction data, average debit and credit transaction amounts and average number of transactions per month. The main results of study indicate that different customer categories have statistically significant differences in behaviour, with respect to how customers operate their accounts. This implies that it is important for the banking sector to consider customer gender differences, age differences and race group differences in the relationship strategies which they employ in their multicultural environment. Further research in the area may be necessary before generalisation can be made on all banking customers.

Stereotypes, advertising and social identity : a theoretical study with reference to the university as a space of cultural negotiation

- Description: This study is an investigation into the stereotypes used in advertisements designed to appeal to university students’ sense of having a social identity, taking the situation at Nelson Mandela Metropolitan University (NMMU) as being representative of university campuses as, among other things, social and cultural space. The study assumes that a university is a site of cultural negotiation, and as such may be viewed as a place where identities are formed and readjusted to conform to stereotypes popularised by influential social models as portrayed in the media. Moreover, with the process of globalization, which distributes stereotypical images globally, one would assume that advertising at NMMU functions in a similar way to its mode of functioning in most parts of the world. Although such media (advertisements) exist in various forms, the scope of the research for this study was limited to print advertisements. Advertisements relevant to the concerns of this study are found everywhere at South African universities. Today, the latest trend for companies like Mr. Price, Standard Bank, Truworths, Red Bull, and Axe, among others, is to sponsor university events, that way creating the opportunity to advertise their products or services to students. Moreover, the notice boards of South African universities are filled with posters advertising new products in the market. In addition to all this, the general South African goods and services market is flooded with magazines that contain stereotype-promoting advertisements targeting students or, in general, young adults. For the purposes of this study, a ‘stereotype’ is understood as an iconic site of identification which functions as a generalized model for social behaviour. In this sense, a ‘stereotype’ may also be understood as a representation of an ‘ideal self’. The purpose of this study is threefold: firstly, to show how and why students may be vulnerable to the stereotypes identified in terms of Lacan’s theory of the ‘mirror stage’; secondly, to identify and categorize the various stereotypes used in advertising to appeal to the student’s sense of social identity, and thirdly, to show that advertisements can be misleading in so far as stereotyping ignores the specificity of every student’s personal social situation and creates false expectations on the part of the target students.

- Identifier: vital:8696 , http://hdl.handle.net/10948/1095 , Women executives -- South Africa
- Description: The study was concerned with identifying both organisational and personal strategies utilised by females in managerial positions within South Africa. From an analysis of both primary and secondary data, it was concluded that executive women in South Africa are utilising personal strategies more extensively than relying solely on organisational strategies to facilitate them to managerial positions and the respondents therefore deemed these personal strategies to have a greater impact than that of the organisational strategies. Both organisations and individuals would benefit from this study as the study brings to the fore the lack of organisational strategies utilised by organisations within South Africa, as well as highlighting those strategies found most beneficial by executive women as having the greatest impact on their careers. This indication would allow for organisations to efficiently invest in those strategies having the most impact on female executives’ careers. Individual women at non-management or junior management levels could integrate the personal strategies highlighted in this study as being most effective into their career development plans. By ensuring both organisations and women together are working to equip females for managerial positions, both organisational and personal performance of South African female managers will be maximized.

- Description: The formal recognition of traditional healing has been controversial for some time with traditional healers being labelled by those of conventional medical orientation as a medical hazard and purveyors of superstition. The support for the development of traditional medicine and establishment of co-operation between traditional healers and allopathic heath practitioners was first promoted in the international health arena by the World Health Organisation. Estimating that 80% of the population living in rural areas of many developing countries was using traditional medicine for the primary healthcare needs, this organisation advocated for the establishment of mechanisms that would facilitate strong cooperation between traditional healers, scientists and clinicians. The study was undertaken in the Amathole District Municipality, Province of the Eastern Cape based on Chapter 2, Section 6(2) (a) of the Traditional Health Practitioners Bill 2003, which required regulation and promotion of liaison between traditional health practitioners and other health professionals registered under any law. The purpose of the study was to develop and propose strategies to facilitate collaboration between traditional and allopathic health practitioners to optimise and complement healthcare delivery. The conceptual framework guiding the study was derived from Leininger’s theory of Cultural Care Diversity and Universality chosen because of its appropriateness. The terms used throughout the study were defined to facilitate the reader’s understanding. Ethical principles were adhered to throughout the research process. To ensure trustworthiness of the study, Guba’s model (in Krefting,1991:214-215) was used where the four aspects of trustworthiness namely, truth value, applicability, consistency and neutrality were considered. A qualitative, exploratory, descriptive and contextual research design was used which assisted in articulating the appropriate strategies to develop to facilitate v collaboration between allopathic and traditional health practitioners. The study was done in two phases. Phase one entailed data collection using unstructured interviews, a focus group interview, literature control and modified participant observation. In Phase two strategies to facilitate collaboration between allopathic and traditional health practitioners were developed. The population in this study comprised three groups of participants. Group 1 consisted of allopathic health practitioners, Group 2 comprised traditional healers and Group 3 was composed of participants who were trained as both traditional healers and allopathic health practitioners. All participants had to respond to three research questions which aimed at: exploring and describing the nature of the relationship between allopathic and traditional health practitioners before legalisation of traditional healing and their experience as role-players in the healthcare delivery landscape in the Amathole District Municipality. eliciting the viewpoints of allopathic and traditional health practitioners regarding the impact on their practices of legalisation of traditional healing and developing strategies to facilitate collaboration between allopathic and traditional health practitioners. Data obtained from each group was analysed using Tesch’s method as described by Creswell (2003:192). Themes emerging from data and the corresponding strategies to address the themes were identified for each group. The participants’ responses to the three research questions revealed areas of convergence and divergence. Of significance was the reflection by the participants on their negative attitude towards each other. They also highlighted that there was no formal interaction between traditional and allopathic health practitioners in the Amathole District Municipality. Their working relationship was characterised by a one-sided referral system with traditional healers referring patients to allopathic health practitioners but this seemed not to be reciprocated vi by the latter group. The exception was the case of traditional surgeons whose working relationship with allopathic health practitioners was formally outlined in the Application of Health Standards in the Traditional Circumcision Act, Act No.6 of 2001. Allopathic health practitioners attributed their negative attitude as emanating from the unscientific methods used by traditional healers in treating patients, interference of traditional healers with the efficacy of hospital treatments and delays by traditional healers in referring patients to the hospitals and clinics. Traditional healers stated that they were concerned about failure of allopathic health practitioners to refer patients who talked about “thikoloshe” and “mafufunyana” to the traditional healers. Consequently, these patients presented themselves to the traditional healers when the illness was at an advanced stage. A reciprocal referral system was perceived by the traditional healers as the core element or crux of collaboration. There were ambivalent views regarding the impact of legalisation of traditional healing on the practices of both traditional and allopathic health practitioners. Elimination of unscrupulous healers, economic benefits, and occupational protection were benefits anticipated by traditional healers from the implementation of the Act. The possibility of having to divulge information regarding their traditional medicines, monitoring of their practice resulting in arrests should errors occur were however, cited by traditional healers as threatening elements of the Act. A lack of understanding the activities of each group with an inherent element of mistrust became evident from the participants’ responses. Ways of fostering mutual understanding between them were suggested which included holding meetings together to discuss issues relating to healing of patients, exposing both groups of health practitioners to research, as well as training and development activities. The participants also highlighted areas of collaboration as sharing resources namely, budget, physical facilities, equipment and information and role clarification especially pertaining to disease management. The participants vii strongly suggested that there should be clarity on the type of diseases to be handled by each group. The need for capacity building of traditional and allopathic health practitioners in preparation for facilitating collaboration was advocated by all and the relevant activities to engage into were suggested. Analysis, synthesis and cross referencing of the themes that emerged from the data culminated in the identification of three strategies that were applicable to all groups of participants and which would assist in facilitating collaboration between allopathic and traditional health practitioners. The researcher coined the three strategies “Triple C” strategies abbreviated as the TRIC strategies. The first “C” of the three “Cs” stands for “change attitude”, the second “C” for “communication” and the third “C” for “capacity building.” Each of the proposed three strategies is discussed under the following headings:- Summary of findings informing the strategy Theory articulating the strategy Aim of the strategy Suggested implementation mechanism As the strategies had to be grounded in a theory which would serve as a reference point, the researcher used the Survey List by Dickoff, James and Wiedenbach (1968:423) as a conceptual framework on which to base the proposed three strategies. The results of this study and recommendations that have been made will be disseminated in professional journals, research conferences and seminars.

- Description: This dissertation is a journey through the legislative changes and case law in order to analyse and evaluate the changing nature of South African jurisprudence in respect of the notions of equality, discrimination and affirmative action and the manner in which these issues are proved and dealt with in our courts. It focuses firstly on the emergence of the post-Wiehahn labour laws and the developing jurisprudence concerning discrimination in South Africa towards the end of a long period of isolation from the international world. It witnesses the growing cognizance which was taken of international guidelines and their slow and gradual incorporation into our jurisprudence before the institution of the new democratic government, in the days when the country was still firmly in the grip of a regime which prided itself on its discriminatory laws. It also deals in some depth with the new laws enacted after the first democratic government was installed, especially in so far as the Constitution was concerned. The first clutch of cases dealing with discrimination which were delivered by the Constitutional Court and their effects on decisions of the labour courts thereafter, are dealt with in great detail, indicating how important those judgments were and still are ten years later. A special chapter is devoted to the Harksen case, still a leading authority on how to deal with allegations of unfair discrimination. Having traversed several of the judgments of the labour courts after Harksen, several observations are made in the conclusion of the study which, it is hoped, summarize the major areas of concern in respect of the task of testing claims of unfair discrimination arising in our Courts.

- Description: In this dissertation novel non-leaving groups were employed to synthesize platinum complexes which can contribute to the understanding or improvement of anticancer action. These complexes basically consist of (NS)-chelate and amineplatinum complexes. Bidentate (NS)-donor ligands were used as non-leaving ligands in the syntheses of platinum(II) complexes with iodide, chloride, bromide and oxalate anions as leaving groups. These complexes were synthesized and studied since many questions regarding the interaction of sulfur donors and platinum still exists. These relate to thermodynamic and kinetic factors and their influence on anticancer action. In this dissertation the properties of novel platinum(II) complexes of a bidentate ligand having an aromatic nitrogen-donor atom in combination with a thioethereal sulfur atom capable of forming a five membered ring with platinum(II) were studied. The general structure of the (NS) -ligands used were N-alkyl-2-methylthioalkyl imidazole. Alkyl groups used were methyl, ethyl and propyl. Although amine complexes of platinum have been extensively studied there are some new aspects of these that are worthwhile investigating. In this dissertation amines having planar attachments which will be at an angle with the coordination plane viz. benzylamine and amines having cyclic aliphatic groups namely cyclopropyl and cyclohexyl were investigated. Some of the (NS) - and amineplatinum(II) complexes were oxidised to their mononitroplatinum(IV) analogues . The motivation for the synthesis of these complexes was the greater kinetic stability of platinum(IV) and recent research has shown that a specific type of platinum(IV) compound shows suitable properties as an anticancer agent. These complexes were characterised by a variety of spectral means (IR, NMR, mass spectroscopy) as well as elemental analysis, solubility determinations, thermal analysis (TGA), ionization studies and finally their anticancer behaviour towards three different cell lines(Hela, MCF 7, Ht29) and in this process they were compared to the behaviour of cisplatin as a reference. A few have shown promising anticancer behaviour.

- Description: Addiction is a complex social phenomenon resulting from psychological and physiological dependence. The aim of the study was to create a clinical impression of the lived experiences of cocaine dependents. A transcendental phenomenological approach was used to elicit the essence of addiction as experienced by the participants. Theoretical sampling ensured relevant participants were selected through haphazard sampling procedures. Data was collected through the use of biographical questionnaires and individual, semi-structured interviews with three cocaine dependents. Data was processed according to the four phenomenological principles epoche, phenomenological reduction, imaginative variation and synthesis using Tesch’s eight steps. The essence of cocaine dependency is contained in the psychological experiences of the drug which define and perpetuate that addiction. The psychological addiction develops prior to physical dependence resulting in an entrenched addiction before treatment is sought by the cocaine dependents.

- Description: The focus of this treatise is to explore the attitudes and perceptions of university students towards binge drinking at a South African University. Binge drinking among university students is a serious concern, prevalent on many campuses and ingrained on university campuses worldwide. The aims of this study were (a) to describe students’ understanding of binge drinking, (b) to explore and describe university students’ attitudes towards and perceptions of binge drinking, and (c) to explore the contextual factors relating to binge drinking within a university setting. An exploratory, qualitative approach was utilized. The collection of data was initiated using a biographical questionnaire to identify participants relevant to the study. The data collection process continued with semi‐structured focus group interviews. Data was collected by conducting four focus group sessions with two separate groups of students between the ages of 18 and 25 and residing on a university campus. Data analysis was conducted in accordance with the principles and guidelines of Tesch’s (as cited in Creswell, 1994) eight steps in qualitative data analysis. The results of this study indicate the following: there is lack of knowledge and understanding of binge drinking, students have positive perceptions of binge drinking and there is a perception that the university environment promotes binge drinking. In order to address binge drinking, strategies need to be implemented in the student, family, university and community context.

- Description: Construction management competencies are essential to realise sound practices among and to realise optimum performance by, inter alia, emerging civil engineering contractors. Such competencies enable a clear focus on the business of construction and the management of projects, with increased efficiency and reduced costs as a benefit. The objective of the MSc (Built Environment) treatise study were to determine the current practices and performance of emerging civil engineering construction contractors operating in the Nelson Mandela Bay Metropole. The descriptive method was adopted in the empirical study. The salient findings of the study are: most of the emerging civil engineering construction contracting organisations lack construction management competencies; construction resources are inappropriately managed leading to construction failures; most of the emerging civil engineering construction contracting organisations lack adequate supervision resulting to poor workmanship; there is a shortage of skilled labour amongst emerging civil engineering construction contractors; procurement processes are inappropriate leading to under capacitated emerging civil engineering construction contracting organisations being awarded contracts; most emerging civil engineering construction contracting organisations lack the requisite aptitude for construction; there is a lack of capacity at all management levels of emerging civil engineering construction organisations in managing the business of construction and that of projects; the nine functions of organisations are not comprehensively represented, and self-ratings indicate inadequacy relative to the management function of control, and relative to certain activities of the organising function. Conclusions include that emerging civil engineering construction contracting organisations need to be comprised of technical teams that possess adequate competencies and that use the construction technology to its full use enabling their organisations to stay abreast of their competitors. Recommendations that can contribute towards improving the status quo include: formal civil engineering and construction management education, resources must be present and training should be promoted throughout the industry at all levels of management to ensure proper supervision and correct use of adequately trained labour, skilled or semi-skilled, incapacitated emerging civil engineering construction contractors should be awarded contracts through appropriately and structured procurement procedures, adequate aptitude in construction should be promoted and enhanced in order to realise conceptualisation and visualisation capabilities, comply with legislation, maintain records and communicate using state of the art technology, optimally manage the finances, have the requisite resources and undertake the work efficiently, interact with the respective publics, and market the organisation to ensure sustainability thereof.

- Description: The purpose of having labour laws in South Africa is to regulate employment contracts and the relationship between the employer and the employee. Once a legally binding contract comes into being the Labour Relations Act of 1995 automatically applies alongside the Basic Conditions of Employment Act and various other labour legislations. Common law rules play a vital role in the formation of an employment contract. For an ordinary contract to have legal effect, four basic requirements need to be met. Briefly, parties to the contract must have reached consensus, parties’ performance of their obligations must be possible, the conclusion and objectives of the contract must be lawful and that both parties to the contract must have the necessary capacity to conclude the contract. Once these requirements have been met one is said to have concluded a valid contract. Nevertheless for the purposes of this study, we focus specifically on the employment contract. Aside from the general common law requirements for a valid contract, for an employment contract to be recognised and protected by labour legislations, it is important to distinguish an employee from an independent contractor since only the former enjoys legal remedies afforded by labour law. Common law contractual rights and duties automatically apply once an employment relationship is established in addition to the rights and duties specified in the contract itself. Common law rules regarding morality plays a major role in our modern day societies, as shall be discussed the workforce has not been left untouched by this important principle. Morality greatly influences a society’s view concerning acceptable and unacceptable behaviour or practices. It goes without saying that a contract should not be contrary to the moral views of the society in which the parties find themselves in. A contract can be complying with all the statutory requirements for a valid employment contract; however it may at the same time be tainted with illegality as the object of performance is considered immoral in the society such as an employment contract to perform prostitution. Conversely, another scenario may involve a party to an employment contract who is a child below the age of 15 years old; the contract is invalid as it contravenes section 43 of the Basic Conditions of Employment Act. Despite clear statutory prohibitions this practice may be perfectly acceptable in the eyes and minds of the society. The purpose of this study is to evaluate prohibited and unlawful contracts of employments, how the law (both common law and statutory law) treats such contracts in the sense that; whether they are protected or not and to what extent these laws have been developed to influence modern attitudes concerning such contracts. One stark example is illustrated through case law where the court had to determine the validity of an employment contract concluded between an employer and an illegal immigrant.

- Description: The neutral distorted octahedral complexes [ReOCl(L)] {H2L = N,N-bis(2- hydroxybenzyl)-2-(2-aminoethyl)dimethylamine (H2had), N,N-bis(2-hydroxybenzyl) aminomethylpyridine (H2hap); N,N-bis(2-hydroxybenzyl)-2-(2-aminoethyl)pyridine (H2hae)} were prepared by the reaction of trans-[ReOCl3(PPh3)2] with a twofold molar excess of H2L in ethanol. The X-ray structure determinations of [ReOCl(had)] and [ReOCl(hap)] were performed, and in both complexes the chloride is coordinated trans to the tripodal tertiary amino nitrogen, with a phenolate oxygen trans to the oxo oxygen. Treatment of trans-[ReO2(py)4]I with two equivalents and one equivalent each of H2had in acetone afforded the iodide salts of the oxypyridinium-ammonium zwitterions N1-(2-hydroxybenzyl)-N2,N2- dimethyl-N1-((2-oxypyridinium)-1-methyl)ethane-1,2-diamine [Hhpd]+ and N2,N2- dimethyl-N1-bis((2-oxypyridinium)-1-methyl)ethane-1,2-diamine [dod]+ respectively. In [Hhpd]I, one of the 2-hydroxyphenyl groups of H2had is substituted by an oxypyridinium group, and in [dod]I, both 2-hydroxyphenyl groups are converted. The X-ray crystal structure determination of the starting material H2had, [Hhpd]I and [dod]I reveals trigonal pyramidal geometries around the central amino nitrogen. The complex salt [ReO(bsa)]PF6 (H2bsa=bis(N-methylsalicylicylideneiminopropyl) amine) was prepared from the reaction of cis-[ReO2I(PPh3)2] with H2bsa in toluene. The dianionic pentadentate ligand bsa is coordinated to the ReO3+ moiety via one secondary amino and two imino nitrogens, and two anionic phenolate oxygens. The complex was characterized by spectroscopy and analytical data, and the structure has been determined by single-crystal X-ray diffraction analysis. The complex exhibits a distorted octahedral geometry around the central rhenium(V) ion, with the basal plane being defined by a phenolate oxygen, two imino nitrogens and the secondary amino. ix A. Abrahams Nelson Mandela Metropolitan University The reaction of a two-fold molar excess of the potentially NN-donor ligand 2,2’- dipyridylamine (dpa) with trans-[ReO(OEt)Cl2(PPh3)2] in ethanol led to the isolation of [ReOCl2(OEt)(dpa)]. The X-ray crystal structure shows that the NN-chelated dpa is coordinated in the equatorial plane cis to the oxo and ethoxo groups, which are in trans positions relative to each other. The treatment of trans- [ReOCl3(PPh3)2] with a tenfold molar excess of dpa in ethanol at the refluxing temperature yielded the trans-dioxo complex [ReO2(dpa)2]Cl, but with a twofold molar excess only (μ-O)[{ReOCl2(dpa)}2] was isolated. Repeating the latter reaction with (n-Bu4N)[ReOCl4] as starting material in ethanol at room temperature a dark green product, also with the formulation (μ-O)[{ReOCl2(dpa)}2], was isolated. The reaction of equimolar quantities of bis(pyridin-2-yl)methyl)amine (HBPA) with (n-Bu4N)[ReOCl4] in acetone at room temperature led to the isolation of the sixcoordinate rhenium(V) complex [ReOCl(H2O)(BPA)]Cl. IR, NMR and X-ray crystallographic results indicate that BPA is coordinated as a tridentate uninegative chelate, with deprotonation of the amine nitrogen. The water molecule is coordinated trans to the oxo group, with the Re=O and Re-OH2 bond distances equal to 1.663(9) and 2.21(1) Å respectively. Complexes of the general formula [ReOX2{(C5H4N)CH(O)CH2(C5H4N)}] (X = Cl, I) were prepared by the reactions of trans-[ReOCl3(PPh3)2] and trans- [ReOI2(OEt)(PPh3)2] with cis-1,2-di-(2-pyridyl)ethylene (DPE) in ethanol and benzene in air. Experimental evidence shows that the coordinated DPE ligand has undergone addition of water at the ethylenic carbons, and that the (C5H4N)CH(O)CH2(C5H4N) moiety acts as a uninegative tridentate NON-donor ligand. The X-ray crystal structures of both complexes show a distorted octahedral geometry around the rhenium(V) centre. The treatment of trans-[ReOCl3(PPh3)2] with H2dbd in a 2:1 molar ratio in acetonitrile led to the isolation of the ligand-bridged dimer (μ-dbd)[ReOCl2(PPh3)]2. The X-ray crystal structure of the complex reveals a dinuclear structure in which two rhenium(V) ions are bridged by the dbd ligand. Each rhenium ion is in a x A. Abrahams Nelson Mandela Metropolitan University distorted octahedral geometry. The basal plane is defined by a phosphorus atom of the PPh3 group, two chlorides cis to each other, and a pyridyl nitrogen atom of dbd. The oxo group and alcoholate oxygen of dbd lie in trans axial positions. The complexes cis-[ReOX2(msa)(PPh3)] (X = Cl, Br, I) were prepared from trans- [ReOCl3(PPh3)2], trans-[ReOBr3(PPh3)2] or trans-[ReOI2(OEt)(PPh3)2] with 2-(1- iminoethyl)phenol (Hmsa) in acetonitrile. An X-ray crystallographic study shows that the bonding distances and angles in the comlexes are nearly identical, and that the two halides in each complex are coordinated cis to each other in the equatorial plane cis to the oxo group. The oxo-bridged dinuclear rhenium(V) complex [(μ-O){ReOCl(amp)}2] was prepared by the reaction of trans-[ReOCl3(PPh3)2] and 6-amino-3-methyl-1-phenyl- 4-azahept-2-ene-1-one (Hamp) in acetone. The characterization of the complex by elemental analysis, infrared and 1H NMR spectroscopy and X-ray crystallography shows that amp is coordinated as a monoanionic NNO-donor chelate as an amino-amido ketone. However, the reaction of the similar ligand 7- amino-4,7-dimethyl-5-aza-3-octen-2-one (Hada) with [Re(CO)5Br] produced the product fac-[Re(CO)3Br(Hada)], with Hada coordinated as a neutral NN-donor amino-imino-ketone.

Treatment of trans-[ReO2(py)4]I with two equivalents and one equivalent each of H2had in acetone afforded the iodide salts of the oxypyridinium-ammonium zwitterions N1-(2-hydroxybenzyl)-N2,N2- dimethyl-N1-((2-oxypyridinium)-1-methyl)ethane-1,2-diamine [Hhpd]+ and N2,N2- dimethyl-N1-bis((2-oxypyridinium)-1-methyl)ethane-1,2-diamine [dod]+ respectively. In [Hhpd]I, one of the 2-hydroxyphenyl groups of H2had is substituted by an oxypyridinium group, and in [dod]I, both 2-hydroxyphenyl groups are converted. The X-ray crystal structure determination of the starting material H2had, [Hhpd]I and [dod]I reveals trigonal pyramidal geometries around the central amino nitrogen. The complex salt [ReO(bsa)]PF6 (H2bsa=bis(N-methylsalicylicylideneiminopropyl) amine) was prepared from the reaction of cis-[ReO2I(PPh3)2] with H2bsa in toluene. The dianionic pentadentate ligand bsa is coordinated to the ReO3+ moiety via one secondary amino and two imino nitrogens, and two anionic phenolate oxygens. The complex was characterized by spectroscopy and analytical data, and the structure has been determined by single-crystal X-ray diffraction analysis. The complex exhibits a distorted octahedral geometry around the central rhenium(V) ion, with the basal plane being defined by a phenolate oxygen, two imino nitrogens and the secondary amino. ix A. Abrahams Nelson Mandela Metropolitan University The reaction of a two-fold molar excess of the potentially NN-donor ligand 2,2’- dipyridylamine (dpa) with trans-[ReO(OEt)Cl2(PPh3)2] in ethanol led to the isolation of [ReOCl2(OEt)(dpa)]. The X-ray crystal structure shows that the NN-chelated dpa is coordinated in the equatorial plane cis to the oxo and ethoxo groups, which are in trans positions relative to each other. The treatment of trans- [ReOCl3(PPh3)2] with a tenfold molar excess of dpa in ethanol at the refluxing temperature yielded the trans-dioxo complex [ReO2(dpa)2]Cl, but with a twofold molar excess only (μ-O)[{ReOCl2(dpa)}2] was isolated. Repeating the latter reaction with (n-Bu4N)[ReOCl4] as starting material in ethanol at room temperature a dark green product, also with the formulation (μ-O)[{ReOCl2(dpa)}2], was isolated. The reaction of equimolar quantities of bis(pyridin-2-yl)methyl)amine (HBPA) with (n-Bu4N)[ReOCl4] in acetone at room temperature led to the isolation of the sixcoordinate rhenium(V) complex [ReOCl(H2O)(BPA)]Cl. IR, NMR and X-ray crystallographic results indicate that BPA is coordinated as a tridentate uninegative chelate, with deprotonation of the amine nitrogen. The water molecule is coordinated trans to the oxo group, with the Re=O and Re-OH2 bond distances equal to 1.663(9) and 2.21(1) Å respectively. Complexes of the general formula [ReOX2{(C5H4N)CH(O)CH2(C5H4N)}] (X = Cl, I) were prepared by the reactions of trans-[ReOCl3(PPh3)2] and trans- [ReOI2(OEt)(PPh3)2] with cis-1,2-di-(2-pyridyl)ethylene (DPE) in ethanol and benzene in air. Experimental evidence shows that the coordinated DPE ligand has undergone addition of water at the ethylenic carbons, and that the (C5H4N)CH(O)CH2(C5H4N) moiety acts as a uninegative tridentate NON-donor ligand. The X-ray crystal structures of both complexes show a distorted octahedral geometry around the rhenium(V) centre. The treatment of trans-[ReOCl3(PPh3)2] with H2dbd in a 2:1 molar ratio in acetonitrile led to the isolation of the ligand-bridged dimer (μ-dbd)[ReOCl2(PPh3)]2. The X-ray crystal structure of the complex reveals a dinuclear structure in which two rhenium(V) ions are bridged by the dbd ligand. Each rhenium ion is in a x A. Abrahams Nelson Mandela Metropolitan University distorted octahedral geometry. The basal plane is defined by a phosphorus atom of the PPh3 group, two chlorides cis to each other, and a pyridyl nitrogen atom of dbd. The oxo group and alcoholate oxygen of dbd lie in trans axial positions. The complexes cis-[ReOX2(msa)(PPh3)] (X = Cl, Br, I) were prepared from trans- [ReOCl3(PPh3)2], trans-[ReOBr3(PPh3)2] or trans-[ReOI2(OEt)(PPh3)2] with 2-(1- iminoethyl)phenol (Hmsa) in acetonitrile. An X-ray crystallographic study shows that the bonding distances and angles in the comlexes are nearly identical, and that the two halides in each complex are coordinated cis to each other in the equatorial plane cis to the oxo group. The oxo-bridged dinuclear rhenium(V) complex [(μ-O){ReOCl(amp)}2] was prepared by the reaction of trans-[ReOCl3(PPh3)2] and 6-amino-3-methyl-1-phenyl- 4-azahept-2-ene-1-one (Hamp) in acetone. The characterization of the complex by elemental analysis, infrared and 1H NMR spectroscopy and X-ray crystallography shows that amp is coordinated as a monoanionic NNO-donor chelate as an amino-amido ketone. However, the reaction of the similar ligand 7- amino-4,7-dimethyl-5-aza-3-octen-2-one (Hada) with [Re(CO)5Br] produced the product fac-[Re(CO)3Br(Hada)], with Hada coordinated as a neutral NN-donor amino-imino-ketone.

- Description: Family owned businesses play a vital role in the economy of a country, therefore their sustainability and succession is a topic that requires adequate research and analysis. This is required to determine the impact and contribution at a socioeconomic level and future development of the family owned business. Within the Nelson Mandela Metropolitan area previous research has been conducted analysing the above with regard to Greek family businesses. There is a little evidence to suggest similar studies have been conducted on Indian owned family businesses, specifically businesses operating at a third generation level. This research will therefore analyse Indian owned family businesses that are at a minimum level of third generation within the Nelson Mandela Metropolitan area. The purpose is to investigate whether there is any specific cultural attributes of the Indian culture which have contributed to their success.

- Description: The Government of South Africa has placed a lot of emphasis on economic growth and the involvement of Black people in the mainstream of the economy. The implementation of Broad-Based Black Economic Empowerment (B-BBEE) created opportunities for direct empowerment of Black females in ownership and management. The Construction Industry is being challenged to increase the number of Black females in management and ownership levels. Due to the nature of the Industry, only a small population of females considers Construction as a career option. The Industry has also lost a significant number of skilled Engineers and is experiencing a shortage of skilled managers in Middle and Senior Management Levels. The research problem questioned the current state of empowerment for Black women in the Construction Industry as measured against the B-BBEE Scorecard. The literature review focused on the requirements of the B-BBEE scorecard and Construction Charter. The second phase focused on gender equality and the achievements of women in Construction. The research design was done by using questionnaires to the South African Federation of Civil Engineering Contractors (Safcec) members in the Eastern Cape. The research design and survey aimed to determine the status of empowerment in the Construction Industry. With reference to both the literature review and the empirical findings the state of female empowerment can be determined. Therefore iv recommendations and opportunities for further research in this regard can be identified.

- Description: In 2003, a conflict broke out in Darfur, Sudan’s western province, between the mainly “African” rebels and the government forces and their proxy “Arab” militias. It is estimated that about 200,000 people have so far died in the conflict from fighting, disease, and starvation. The UN and aid agencies estimate that over two million Darfurians, out of the population of about six million, are living in refugee camps. Even though the majority of all deaths in Darfur have occurred in 2003 and 2004, the conflict is nowhere near the end. Even after more than five years since the Darfur conflict began, there is hardly any comprehensive information about the rebels’ aims, objectives, and plans for the future. We cannot fully understand the conflict and plan peace negotiations between the warring parties if we do not know enough about the rebels. This study has critically explored the aims and perspectives of the Justice and Equality Movement, currently the most powerful Darfur rebel movement. The author has used the first-hand information gathered through interviews with the representatives of the rebel movement and additional data about the conflict and the rebels collected through an extensive literature analysis to portray the movement and its aims, perspectives, and plans for the future. Using the grounded theory approach as the data analysis tool, the author has presented key findings about the Darfur conflict from the perspective of the Justice and Equality Movement that have emerged from the data collected in this study.

- Description: Eye gaze interaction enables users to interact with computers using their eyes. A wide variety of eye gaze interaction techniques have been developed to support this type of interaction. Gaze selection techniques, a class of eye gaze interaction techniques which support target selection, are the subject of this research. Researchers developing these techniques face a number of challenges. The most significant challenge is the limited accuracy of eye tracking equipment (due to the properties of the human eye). The design of gaze selection techniques is dominated by this constraint. Despite decades of research, existing techniques are still significantly less accurate than the mouse. A recently developed technique, EyePoint, represents the state of the art in gaze selection techniques. EyePoint combines gaze input with keyboard input. Evaluation results for this technique are encouraging, but accuracy is still a concern. Early trigger errors, resulting from users triggering a selection before looking at the intended target, were found to be the most commonly occurring errors for this technique. The primary goal of this research was to improve the usability of gaze selection techniques. In order to achieve this goal, novel gaze selection techniques were developed. New techniques were developed by combining elements of existing techniques in novel ways. Seven novel gaze selection techniques were developed. Three of these techniques were selected for evaluation. A software framework was developed for implementing and evaluating gaze selection techniques. This framework was used to implement the gaze selection techniques developed during this research. Implementing and evaluating all of the techniques using a common framework ensured consistency when comparing the techniques. The novel techniques which were developed were evaluated against EyePoint and the mouse using the framework. The three novel techniques evaluated were named TargetPoint, StaggerPoint and ScanPoint. TargetPoint combines motor space expansion with a visual feedback highlight whereas the StaggerPoint and TargetPoint designs explore novel approaches to target selection disambiguation. A usability evaluation of the three novel techniques alongside EyePoint and the mouse revealed some interesting trends. TargetPoint was found to be more usable and accurate than EyePoint. This novel technique also proved more popular with test participants. One aspect of TargetPoint which proved particularly popular was the visual feedback highlight, a feature which was found to be a more effective method of combating early trigger errors than existing approaches. StaggerPoint was more efficient than EyePoint, but was less effective and satisfying. ScanPoint was the least popular technique. The benefits of providing a visual feedback highlight and test participants' positive views thereof contradict views expressed in existing research regarding the usability of visual feedback. These results have implications for the design of future gaze selection techniques. A set of design principles was developed for designing new gaze selection techniques. The designers of gaze selection techniques can benefit from these design principles by applying them to their techniques

- Description: The synthesis of p-menthane-3,8-diol via the acid-catalyzed cyclization of citronellal in a dilute aqueous sulphuric acid medium was investigated using conventional batch and continuous systems in order to develop a commercial production process for said p-menthane-3,8-diol (PMD). The batch studies conducted during the first part of this study showed that the formation of PMD from citronellal occurs via an intra-molecular Prins reaction that results in the formation of both the desired PMD product, as well as the partially hydrated isopulegol. It was shown that the formationof the by- product, PMD-acetal, results from the reaction between an intermediate, 5-methyl-2- isopropylcyclohexanol, and the citronellal starting material, and not from the reaction between PMD and citronellal as previously reported. Kinetic studies confirmed the existence of a complicated kinetic model. The formation of PMD from citronellal displayed typical pseudo first order kinetics up to conversions of 70 after which the kinetic model becomes complicated as the result of the establishment of quasi equilibrium reactions between PMD and isopulegol (dehydration of PMD and hydration of isopulegol) and between PMD the PMD-acetal, both systems being acid catalysed. The PMD-acetal formation reaction appears to be second order with respect to PMD. Scale-up studies of the batch process to 30L and 50L scales showed that it would be extremely difficult to limit the level of PMD-acetal formation below the desired level of 1 percent, even if citronellal conversions are restricted to about 50 percent. During studies conducted on a commercially availablemicro-structured organic synthesis plant (OSP) it was shown that it is possible to perform the PMD reaction as a continuous process. The results obtained showed that the use of a micro-mixer such as the caterpillar micro-mixer did not provide enough residence time in order for desirable conversions (- 40 percent) to be obtained. By combining themicro-mixer with delay-loops of different thicknesses and lengths, and using increasing reaction temperatures, it was shown that the conversion of citronellal could be improved to some extent, but compared poorly to the expected conversions for a well-stirred batch reactor. By packing selected delay loops with inert SiC particles, improved mass transfer was observed between the organic and aqueous phases as reflected in the increased conversion of citronellal. Using the observations that were made during the use of the OSP, a continuous-flow, tubular reactor system was designed and constructed. Advanced statistical techniques were used to investigate the effect of variables such as temperature, acid concentration, reactor length, flow rate and the organic to aqueous ratio on the rate and selectivity of the reaction. Mathematical models were derived for citronellal conversion, yield of PMD and yield of PMD- acetals, and used to predict the concentrations of citronellal, PMD and PMD-acetals at set experimental conditions. The results obtained showed that it was possible to obtain a product which approached desired specifications.Downstream processing of the PMD reaction mixture as it exits the reactor requires phase separation and neutralization of the acid catalyst solution, followed by further work-up to recover unreacted starting material and intermediates for recycle back to the synthesis reactor, followed by purification of crude PMD to the desired specification. The study showed that neutralization, prior or after phase separation, does not affect the selectivity of the PMD to such a great extent, but does influence the relative conversion due to extended contact of the catalyst with the organic phase after the reaction is terminated. Recovery of unreacted citronellal and isopulegol could be achieved by a simple vacuum evaporation step, which may either be carried out in a batch manner using traditional distillation equipment, or in a continuous process using wiped-film (short path) techniques. It was also shown that selective crystallization of PMD from the crude product mixture by addition of a solvent, such as heptanes or hexane proved to be the best way of achieving the desired product specification.

- Description: The research problem addressed in this study was to provide a planning guideline for Small, Medium and Micro Enterprises (SMME’s) to assist them to plan more effectively and be sustainable in their businesses. A guideline for planning is needed, as planning is one of the most difficult activities a business owner needs to undertake. Yet it is essential to do because, before taking action, you must know where you are going and how to get there. Well-developed plans can assist the business owner to interest banks and/or investors to invest in the business, guide the owner in operating the business, give direction to and motivate employees, and provide an environment to attract customers and prospective employees. To become an effective business owner, one must look ahead. Planning, which is the process of setting objectives and devising actions to achieve those objectives are imperative to be sustainable in business. The findings of the literature survey clearly highlights the reasons why a business owner needs to plan and provide a guideline how to plan. It was found in the empirical study that Standard Bank rate the SMME market as a very valuable part of their business. The SMME market has a benefit to various departments within the bank, not only the SMME business market. The empirical study also found that not every entrepreneur that holds a business plan is successful. Many reasons for this exist. One aspect that was identified, is that the wrong idea was implemented. The empirical study revealed that in all respondents agreed that planning forms an integral part of the entrepreneurs business. The empirical study found that a business plan will assist the entrepreneur to be sustainable in their business, only if a thorough feasibility study was conducted. The respondents agreed that the feasibility study, will either support or contradict the assumptions made in the business plan, this will assist the entrepreneur to decide to either continue or end the business activity. It was found that the entrepreneur, with especially a financial expert should be involved when a business planning is undertaken. Other experts in the various business arenas should also be requested to assist with the setting up of the business plan.

- Description: The research problem addressed in this study was to provide a planning guideline for Small, Medium and Micro Enterprises (SMME’s) to assist them to plan more effectively and be sustainable in their businesses. A guideline for planning is needed, as planning is one of the most difficult activities a business owner needs to undertake. Yet it is essential to do because, before taking action, you must know where you are going and how to get there. Well-developed plans can assist the business owner to interest banks and/or investors to invest in the business, guide the owner in operating the business, give direction to and motivate employees, and provide an environment to attract customers and prospective employees. To become an effective business owner, one must look ahead. Planning, which is the process of setting objectives and devising actions to achieve those objectives are imperative to be sustainable in business. The findings of the literature survey clearly highlights the reasons why a business owner needs to plan and provide a guideline how to plan. It was found in the empirical study that Standard Bank rate the SMME market as a very valuable part of their business. The SMME market has a benefit to various departments within the bank, not only the SMME business market. The empirical study also found that not every entrepreneur that holds a business plan is successful. Many reasons for this exist. One aspect that was identified, is that the wrong idea was implemented. The empirical study revealed that in all respondents agreed that planning forms an integral part of the entrepreneurs business. The empirical study found that a business plan will assist the entrepreneur to be sustainable in their business, only if a thorough feasibility study was conducted. The respondents agreed that the feasibility study, will either support or contradict the assumptions made in the business plan, this will assist the entrepreneur to decide to either continue or end the business activity. It was found that the entrepreneur, with especially a financial expert should be involved when a business planning is undertaken. Other experts in the various business arenas should also be requested to assist with the setting up of the business plan.

- Description: There is an escalation of HIV and AIDS among the youth in South Africa and other developing countries. Research on HIV and AIDS risk factors has tended to focus more on poverty, gender, race, illiteracy, and violence than personality factors that could influence an individual` s health-protective behaviour. Previous studies have also shown that wealth, education, race, and gender may not make an individual more or less vulnerable to HIV infection. This study argued that locus of control could influence an individual` s health-protective behaviour and that external locus of control could be a risk factor in HIV and AIDS risk reduction. The aim of this study was to investigate the efficacy of a locus of control-based training programme in reducing HIV and AIDS risk among university students. The locus of control-based variables that formed the training programme for HIV and AIDS risk reduction among university students were: social systems control, self-control, fatalism, achievement-oriented behaviour, deferment of gratification, personal values and expectancies, and social alienation. These locus of control-based variables were regarded as contexts in which individuals could exhibit health risk behaviours. A sample of 257 first-year university students participated in the study. There were (N = 170) female participants and (N = 87) male participants drawn from the University of the Witwatersrand. The study was a pretest-posttest repeated measures design. Data were analysed using t tests, correlations, multiple regression, structural equation modelling, and repeated measures tests. The results of this study showed significant differences in health risks between participants with an external locus of control and participants with an internal locus of control. There was a significant relationship between locus of control-based variables and HIV and AIDS risk. The locus of control-based training programme significantly modified personality and significantly reduced locus of control-based health risks and HIV and AIDS risk. Directions for future research on locus of control, health risks, and HIV and AIDS risk could focus on the development and implementation of various locus of control-based training programmes in South Africa. Locus of control should be targeted as a health risk factor in HIV and AIDS risk reduction training programmes.
