- Description: Policing as a global concept, involves an exchange of trust between the public and a given police service, with the underlying basis of this exchange being an understanding that the police exist to protect citizens and their property, and to ensure that order is maintained in societies. The police services, by virtue of the nature of their role in society, can therefore be regarded as ‘protectors’. The South African Police Service are guided by the same philosophies as policing services globally. Recently in South Africa though, there has been an increase in reports accusing policemen of becoming involved in criminal activities themselves. With a focus on the Buffalo City Metropolitan Municipality policing district, this study presents and analyses incidences of undocumented police crimes; the causes thereof; and the role of disciplinary procedures (both internally and legally) in preventing such incidences of crime. This study utilised a qualitative methodology to gather and analyse data. A total of 60 serving police officers and 10 key informants were selected using purposive and snowball sampling. In-depth semi-structured interviews conducted with these police officers and key informants, reveal that police men and women are involved in violent and economic crimes in the Buffalo City Metropolitan Municipality policing district. Most violent crimes include assault, and torture; whilst economic crimes include corruption and theft. Underlying reasons for such crimes include inadequate remuneration, frustration in respect of the efficacy of the criminal justice system, vigilantism within the policing services, and socially learned violence. Internal (within SAPS and IPID) and legal disciplinary measures (through the criminal and civil justice system) were established to be ineffective in managing and eradicating incidences of both violent and economic crimes. The consequences of incidences of police criminality are reduced legitimacy of the policing services to deliver on its mandate to protect and serve the people of the Republic of South Africa.

- Description: This study analysed the capacity of Limpopo Water Services Authorities in providing access to clean drinking water and decent sanitation. The study raised issues of the state of access to clean drinkable water and decent sanitation through the prism of the municipality and the community. Arguably, the provision of water and sanitation services collapsed, at the level of local government, during the Jacob Zuma administration, because of the escalation of violent service delivery protests due to poor administration and management. It was discovered that all Water Services Authorities owe the Department of Water Affairs exorbitant amounts of money, well into the range of millions of Rands. This prompted the Water Boards to issue threats that they would limit the provision of bulk water. Such austerity measures compromised citizens who regularly pay for the services provided; hence, it sparked violent protests. One of the major drawbacks of the current institutional arrangements arose from the overlapping mandates of the Department of Water Affairs, Cooperative Governance and Traditional Affairs, Water Services Authorities, Local Municipalities and the Department of Human Settlements. Consequently, the structural design of the intergovernmental system should enforce synergy between all water and sanitation units. The reports produced by all units must be scrutinised, debated and followed through. The study was anchored in a qualitative research design, grounded in the descriptive approach. Interviews were conducted to acquire information from politicians, administrators and community members. It was discovered that there were no skilled personnel in Water Services Authorities and Water Service Providers and, as such, institutional capacity was in disarray. More importantly, during the interviews conducted for this study, it surfaced that financial mismanagement in all municipalities is conspicuously unacceptable, especially unauthorised, irregular and fruitless expenditures. These situations prevailed under the supervision of the well-established oversight institutions that were tasked to enhance the monitoring and evaluation for good governance, such as The Auditor General of South Africa, the Human Rights Commission and the Public Protector. Professionalism and quality performance remain at a low point, with no improvement in service provision. Therefore, radical enforcement of monitoring and evaluation through Auditor General of South Africa, Human Rights Commission and Public Protector, amongst others, is critical to any attempt to disrupt the status v quo. In addition, the appointment of the heads of these oversight institutions must be removed from the Presidency and be made by the Chief Justice. The encounters confronting Water Services Authorities and Water Service Providers are complex and may not be resolved by the government alone, without the participation of the private sector and other actors such as Civil Society Organisations, the business community and public entities. Therefore, an area for further research could be an examination of attempts to introduce effective integrated water and sanitation governance structures, and monitoring and evaluation mechanisms, under robust public scrutiny in order to inform immediate and long-term interventions.

- Description: Ligand-isotope labelling studies were performed on Zeise’s salt derivatives with pyridine N-oxide and quinoline N-oxide, their perdeuterated and O-18 isotopomers, C₂D₄ and ¹³CO, and the results of the vibrational analyses are reported. The isotopomers are modelled utilizing DFT calculations at the B3LYP level with the 6-31 G** basis set, and a pseudopotential level for the Pt atom. The calculated and observed structure and vibrational spectra correlate well. The crystal structures of [Pt(C₂2H₄)(pyO)Cl₂] and [Pt(CO)(quinO)Br₂] are reported. The frequency for the νPt-O vibration, ambiguously assigned in the literature, is here assigned unequivocally at 400 cm⁻¹. Previously observed, but inadequately described phenomena are addressed: the νN-O vibration in substituted quinoline N-oxides has been assigned previously at significantly different frequencies, depending on the nature of the substituent. This suggests that there is no specific mid-ir band associated with a high N-O character. A suitable explanation is presented for this phenomenon, showing that in low symmetry systems (eg. quinO) the N-O stretch is dispersed among several modes, whereas in high symmetry systems (eg. pyO) only a few limited modes have a high N-O character. A theoretical study of Cu(I) carbonyl compounds with macrocyclic ligands is presented. Local and global HSAB parameters applied to the donor and Cu atoms are used to explain the observed reactivities and the available spectroscopic data. Extended to [Cu(CO){H₂N(CH₂)[subscript n]NH(CH₂)[subscript m] NH₂}] BPh₄ (where n = 2, m = 2, 3 and n =3, m = 3, 4) and their -d₅ and ¹³CO isotopomers, subtle differences obtained experimentally for the CO stretching frequency in this series have been reproduced in the DFT calculations at the B3LYP level, using the 6-31 G* and 6-31 G** basis sets. Several properties (ligand pK[subscript a] values, νCO frequencies, etc.) correlate with some HSAB descriptors. Vibrational analyses are presented of Cu(I) carbonyl Schiff-base derivatives of N-Benzylidene-N’-[2-(benzyilidene-amino)-ethyl]-ethane-1,2-diamine, {2,2N3(C₆H₄R)₂}, and their -d₅ and ¹³CO isotopomers. The crystal structure of [Cu(CO){2,2N3(C₆H₅)₂}]BPh₄ is reported. From geometry optimizations and the HSAB descriptors, spectroscopic trends ([n]Cu-N and [nu]CO) are related to calculated global hardness and the Hammett substituent parameters, and are discussed in terms of σ-donation and π-backbonding of Cu- CO.

- Description: he thermal behaviour in the solid state of various substituted aminobenzoic acids (3-aminobenzoic acid (3-ABA), 4-aminobenzoic acid (4-ABA), 3-aminosalicylic acid (3-ASA), 4-aminosalicylic acid (4-ASA), and 5-aminosalicylic acid (5-ASA), as well as the "parent" benzoic acid (BA) and salicylic acid (SA) as reference substances, and possible decomposition products: 2-aminophenol (2-AP), 3-aminophenol (3-AP) and 4-aminophenol (4-AP), has been examined. The various sets of isomers studied showed considerable and interesting differences. Most sublimed well before melting, generally with an increasing rate of mass loss beyond their very different melting points. The existence of ranges of isomers allows for the comparison of their behaviour, including such aspects as melting, vaporisation, and the influence of products on the course of decomposition of initially-solid reactants. The differences in behaviour of 4-ASA and 5-ASA were the most remarkable, with 5-ASA being far more stable and apparently not decarboxylating readily, while 4-ASA sublimed at temperatures below the melting point, becoming less stable and decarboxylating in the liquid form. There is also a marked difference in the thermal behaviour of 3-ASA, as compared with 4-ASA and 5-ASA. It decarboxylated at higher temperatures (260°C) than 4-ASA (150°C). The addition of the possible decomposition products to these compounds showed faster decomposition for 4-ASA mixed with 3-AP. The sodium salts of 3-ASA and 4-ASA decarboxylate while that of 5-ASA did not. Binary mixtures of the substances listed above with beta-cyclodextrin (BCD), hydroxypropylbeta-cyclodextrin (HPBCD) and gamma-cyclodextrin (GCD) were prepared (by simple physical mixing or by kneading with a solvent) and were then examined for possible interactions using DSC, TG-FTIR, HSM, XRD and NMR. Generally, kneaded mixtures showed greater changes in thermal behaviour from that of the individual components than the physical mixtures, but changes in the physical mixtures were also significant. Comparison of the effects of the different CDs on the thermal behaviour of individual ASA isomers showed that HPBCD has the greatest interaction with 3-ASA and 5-ASA, followed by GCD, while BCD generally showed the least interactions. For 4-ASA, the effect of GCD is more marked than for 3-ASA and 5-ASA. GCD has the largest molecular cavity.

A chart is given for the accurate correction of weights in air to weights in vacuum for a range of temperatures extending from 10° to 28°C, and for pressures from 690 to 730 mm. 3. An automatic recycling still has been designed for the continuous production of "ultra-pure" water. This still is capable of delivering daily, in routine operation, 16 l. of water of conductivity less than 100 nm/cm after aeration with "C0₂- and NH₃-free" air. 4. A very soluble layer appears to form on the surface of' glass when it is dried; this layer is readily removed on contact with water. 5. The removal of carbon dioxide and of ammonia from aqueous solution by aeration with an indifferent gas has been fully investigated, and it has been shown that these gases can be completely eliminated by such a process. Whereas the carbon dioxide is removed fairly rapidly, however, the ammonia, whether present alone or together with carbon dioxide, only goes out of solution rather slowly. 6. It has been shown that ammonia is adsorbed from aqueous solution on the glass walls of the cell. 7. There does not appear to be any ammonium bicarbonate in the residual impurity left in the "ultra-pure" water obtained from the still; the impurity can, in fact, be regarded as neutral salt with sufficient accuracy for most purposes. 8. The resistance change which accompanies any variation in the rate of bubbling of the stirring gas through the water has been investigated, but no solution has been found as to the cause of this change. 9. A comparison has been made of the efficiency of different gases for stirring purposes, and it seems that, for general work, nitrogen is by far the most suitable of the common gases. 10.
