- Description: The syntheses and comparative studies of the spectral, voltammetry and spectroelectrochemical properties of new manganese phthalocyanine complexes, tetra-substituted with diethylaminoethanethio at the peripheral (complex 3a) and non-peripheral positions (complex 3b) are reported. Solution electrochemistry of complex 3a showed quasi-reversible metal-based (MnIIIPc−2/MnIIPc−2, E1/2 = −0.07 V vs. Ag|AgCl) and ring-based (MnIIPc−2/MnIIPc−3, E1/2 = −0.78 V vs. Ag|AgCl) reductions, but no ring-based oxidation. However, complex 3b showed weak irreversible ring-oxidation signal (Ep = +0.86 vs. Ag|AgCl). Reversible metal-based (MnIIIPc−2/MnIIPc−2, E1/2 = −0.04 V vs. Ag|AgCl) and ring-based (MnIIPc−2/MnIIPc−3, E1/2 = −0.68 V vs. Ag|AgCl) reductions were also observed for complex 3b. Spectroelectrochemistry was used to confirm these processes. Reduction process involving the metal (MnIIIPc−2/MnIIPc−2) was associated with the formation of manganese μ-oxo complex in complex 3a.

- Description: The synthesis and electrochemical properties of new cobalt and manganese phthalocyanine complexes, tetra-substituted with 3,4-(methylendioxy)-phenoxy at the peripheral (complexes 3 and 5) and non-peripheral (complexes 4 and 6) positions, are reported. Complexes 3 and 4 showed Q-band absorption, in DMF, at 668 and 686 nm, respectively while Q-band due to complexes 5 and 6 appeared at 732 and 760 nm, respectively in CHCl3. All the complexes showed well resolved redox processes attributed to both metal and ring based processes. Complexes 3 and 4 showed four redox processes, labeled I, II, III and IV. For complex 3, process I (CoIPc−2/CoIPc−3) was observed at −1.45 V, II (CoIIPc−2/CoIPc−2) at −0.38 V, III (CoIIIPc−2/CoIIPc−2) at +0.49 V and IV (CoIIIPc−1/CoIIIPc−2) at +0.97 V versus Ag|AgCl. Similar processes were observed for complex 4 at −1.36 V, −0.27 V, +0.56 V, +1.03 V versus Ag|AgCl, respectively. Complexes 5 and 6 showed two redox processes (I and II). For complex 5, these processes appeared at −0.79 V (MnIIPc−2/MnIIPc−3, I) and −0.07 V versus Ag|AgCl (MnIIIPc−2/MnIIPc−2, II), while for complex 6, they were observed at −0.86 V and −0.04 V versus Ag|AgCl.

- Description: Molecular films of manganese phthalocyanine (MnPc) complexes, tetra-substituted with 2-diethylaminoethanethio at the peripheral (Mn(OAc)-β-TDEAETPc, 1) and non-peripheral (Mn(OAc)-α-TDEAETPc, 2) positions were formed on glassy carbon electrode by electropolymerization and electrodeposition respectively. Atomic force microscopy images confirmed the presence of the films and revealed significant morphological differences. The films exhibited an electrocatalytic activity towards the oxidation of the insecticide, bendiocarb. Hydrodynamic technique, using rotating disc electrode voltammetry, was used to investigate the kinetics of electro-oxidation of the insecticide. Morphological differences of the films significantly influenced kinetic parameters. Values of Tafel slopes, obtained from Tafel plots, suggested that catalysis of bendiocarb occurred via outer sphere mechanism.

- Description: The syntheses of new cobalt phthalocyanine (CoPc) complexes, tetra-substituted with diethylaminoethanethio at the peripheral (complex 3a) and non-peripheral (complex 3b) positions, and with benzylmercapto at the non-peripheral position (complex 5), are reported. The effects of the nature and position of substituent on the spectral, electrochemical and spectroelectrochemical properties of these complexes are investigated. Solution electrochemistry of complex 3a showed three distinctly resolved redox processes attributed to CoIIIPc−2/CoIIPc−2 (E½ = +0.64 V versus Ag|AgCl), CoIIPc−2/CoIPc−2 (E½ = −0.24 V versus Ag|AgCl) and CoIPc−2/CoIPc−3 (E½ = −1.26 V versus Ag|AgCl) species. No ring oxidation was observed in complex 3a. Complex 3b showed both ring-based oxidation, attributed to CoIIIPc−1/CoIIIPc−2 species (Ep = +0.86 V versus Ag|AgCl), and ring-based reduction associated with CoIPc−2/CoIPc−3 species (E½ = −1.46 V versus Ag|AgCl), with the normal metal-based redox processes in CoPc complexes: CoIIIPc−2/CoIIPc−2 (Ep = +0.41 V versus Ag|AgCl) and CoIIPc−2/CoIPc−2 (E½ = −0.38 V versus Ag|AgCl). Solution electrochemistry of complex 5 showed the same type and number of species observed in complex 3a: CoIIIPc−2/CoIIPc−2 (Ep = +0.59 V versus Ag|AgCl), CoIIPc−2/CoIPc−2 (E½ = −0.26 V versus Ag|AgCl) and CoIPc−2/CoIPc−3 (E½ = −1.39 V versus Ag|AgCl) species. These processes were confirmed using spectroelectrochemistry.

- Description: When grievances do not get resolved in the workplace, they can turn into disputes of unfair labour practices. The use of an internal dispute resolution mechanism, the grievance procedure, is not a new method for resolving disputes of unfair labour practices within the jurisdiction of the workplace. While some organisations benefit from effectively using the internal dispute resolution mechanism, other organisations seem not to yield positive results when applying the very same internal mechanism. This, therefore, raises the question whether the internal grievance procedures effectively used to resolve disputes of unfair labour practices. The main aim of this research study, therefore, is to assess the application of the internal dispute resolution mechanism in order to determine whether the City of Tshwane Metropolitan Municipality in Pretoria, Gauteng Province of the Republic of South Africa, is effectively applying the internal dispute resolution mechanism to resolve disputes of unfair labour practices in the workplace. To answer the research questions, a literature study was conducted. A literature study was done to find out what other studies have discovered regarding the internal dispute resolution mechanism and unfair labour practices. Deficiencies found in the Labour Relations Act 66 of 1995 (hereinafter referred to as the LRA), the Constitution of the Republic of South Africa, 1996; and the intertwine between the application of the common law and labour law further complicate resolutions of disputes of unfair labour practices. As a result, organisations may not be certain which specific law should mainly be taken into account when dealing with labour matters concerning unfair labour practices. As such, the internal dispute resolution mechanism may not be effectively applied in the workplace to minimise or prevent disputes of unfair labour practices from having a negative impact on the organisation. Once an organisation fails to resolve disputes of unfair labour practices inside the workplace, the efficiency of the organisation is compromised. The organisation is at risk of spending more time and possibly more money when disputes of unfair labour practices are referred to external dispute resolution institutions. An empirical research study using a quantitative research method was used to collect data. A structured online questionnaire was used to collect data from research respondents. A purposive sampling technique was used to obtain data from the personnel who are tasked with the duties and responsibilities of dealing and managing labour relations in the organisation. Respondents consisted of labour relations and human resources practitioners and labour relations and human resources managers. Data was obtained from 16 out of 23 respondents, which resulted in a 69% response rate. Findings of the study indicated that the internal dispute resolution mechanism of the City of Tshwane Metropolitan Municipality was perceived to be ineffective in resolving disputes hence disputes were referred to external dispute institutions. In the process, the organisation incurred costs in terms of time and money. Furthermore, the time it took to resolve disputes of unfair labour practices negatively affected the morale of employees and productivity in the workplace. Although the majority of respondents had the competencies and skills, some individuals felt that the competencies and skills they had were not sufficient to enable them to deal with dispute resolution effectively. As a result, the lack of required competencies and skills affected the process of the dispute resolution of the organisation by causing delays in resolving unfair labour practices in the workplace. The research indicated that there were inconsistencies in the application of procedures regarding resolving disputes relating to unfair labour practices. As such, respondents perceived the grievance procedure as not being effectively used to reduce the number of disputes from escalating to external dispute resolution institutions. Respondents perceived that human resources and labour relations personnel did not apply fairness consistently when dealing with disputes of unfair labour practices. The research study concluded by revealing that the success of the internal dispute resolution mechanism in resolving disputes of unfair labour practices is achieved, and handicapped, by persons who are tasked with the responsibility of dealing and managing labour relations in the workplace.

A literature study was done to find out what other studies have discovered regarding the internal dispute resolution mechanism and unfair labour practices. Deficiencies found in the Labour Relations Act 66 of 1995 (hereinafter referred to as the LRA), the Constitution of the Republic of South Africa, 1996; and the intertwine between the application of the common law and labour law further complicate resolutions of disputes of unfair labour practices. As a result, organisations may not be certain which specific law should mainly be taken into account when dealing with labour matters concerning unfair labour practices. As such, the internal dispute resolution mechanism may not be effectively applied in the workplace to minimise or prevent disputes of unfair labour practices from having a negative impact on the organisation. Once an organisation fails to resolve disputes of unfair labour practices inside the workplace, the efficiency of the organisation is compromised. The organisation is at risk of spending more time and possibly more money when disputes of unfair labour practices are referred to external dispute resolution institutions. An empirical research study using a quantitative research method was used to collect data. A structured online questionnaire was used to collect data from research respondents. A purposive sampling technique was used to obtain data from the personnel who are tasked with the duties and responsibilities of dealing and managing labour relations in the organisation. Respondents consisted of labour relations and human resources practitioners and labour relations and human resources managers. Data was obtained from 16 out of 23 respondents, which resulted in a 69% response rate. Findings of the study indicated that the internal dispute resolution mechanism of the City of Tshwane Metropolitan Municipality was perceived to be ineffective in resolving disputes hence disputes were referred to external dispute institutions. In the process, the organisation incurred costs in terms of time and money. Furthermore, the time it took to resolve disputes of unfair labour practices negatively affected the morale of employees and productivity in the workplace. Although the majority of respondents had the competencies and skills, some individuals felt that the competencies and skills they had were not sufficient to enable them to deal with dispute resolution effectively. As a result, the lack of required competencies and skills affected the process of the dispute resolution of the organisation by causing delays in resolving unfair labour practices in the workplace. The research indicated that there were inconsistencies in the application of procedures regarding resolving disputes relating to unfair labour practices. As such, respondents perceived the grievance procedure as not being effectively used to reduce the number of disputes from escalating to external dispute resolution institutions. Respondents perceived that human resources and labour relations personnel did not apply fairness consistently when dealing with disputes of unfair labour practices. The research study concluded by revealing that the success of the internal dispute resolution mechanism in resolving disputes of unfair labour practices is achieved, and handicapped, by persons who are tasked with the responsibility of dealing and managing labour relations in the workplace.

The impact of water as a security issue on the Middle East peace process: 1991-1996

- Description: In recent years, there has been increasing realisation that resource based conflicts constitute one of the most salient threats to the survival of mankind, namely, water. In particular, the fundamental link between water and security can no longer be ignored given the indispensable role of water in the sustenance of human life as well as crucial sectors of agriculture and industry. Since the flow of water does not respect political boundaries, co-operation in the utilisation of dwindling supplies remains the most sustainable option for the future in an era of ecological interdependence. This thesis endeavours to investigate the impact of water as a security issue on the Middle East peace process. This is done within the theoretical framework that is provided by the schools of complex interdependence and new security studies. With the demise of the cold war, and the emergence of an expanded security agenda, water is an important non-military threat especially in the Middle East region. However, even with an expanded security agenda, the case of the Middle East suggests that it remains difficult to discard the hierarchy of security issues advocated by the Realists. The ongoing debate between the schools of complex interdependence and Realism is instructive in determining whether co-operation over water issues, considered "low" politics, is attainable in the absence of resolving "high" politics concerns of territory and security. Given its profound security implications for the Middle East region, water has been accorded a central role in both the bilateral and multilateral peace negotiations. In the context of water scarcity, and rising demographic patterns, the role of water as a facilitator of regional co-operation remains critical. However, for multilateral co-operation over water resources to become a tangible reality, it is the contention of this thesis that both "low" politics issues of water and "high" polities concerns of territory as well as security must be addressed simultaneously.
