A critique of South African anti-corruption strategies and structures : a comparative analysis

The ill-effects of corruption on the society, polity and economy of a country are far reaching. They have a corrosive effect on the rule of law, on governance and on the welfare of the society. The Constitution of the Republic of South Africa of 1996, which is the supreme law of the country, places as an expectation and obligation on the government accountability of state, and a government free of corruption and the malignancy of economic nepotism. South Africa’s anti-corruption framework is designed as a control-based approach that is multi-faceted and executed through legislation, supporting regulations, audit trails, anti-corruption structures, law enforcement, and public vigilance and reporting structures, amongst others. Be that as it may, South Africa is battling the scourge of corruption and other self-serving behaviours, often amongst the upper echelons of governing power, as demonstrated by the State capture. Some of the acts of corruption stems from the very same institutions that are meant to be the upper guardians of law and order. Numerous corrupt practices occur almost daily, including but not limited to fraud, bribery, extortion, nepotism, conflict of interest, cronyism, favouritism, theft, fronting, embezzlement, influence-peddling, insider trading/abuse of privileged information, bid-rigging and kickbacks and money laundering. The list is not exhaustive. Based on the findings of this study, numerous recommendations and /or suggestions are made. The value of the study lies in the contribution it makes in South Africa’s fight against corruption to become comparable to countries whose corruption perception index is all time favourable, such as Botswana, Seychelles, Hong Kong and Singapore.Criminology and Security ScienceD.

Masculinity as a popular theme in the development of Basotho accordion music

Text in English and some in SesothoThis thesis examined how masculinity develops among the Basotho accordion music artists of the period 1980-2015 with an intention to propose the reshaping of masculinity conducive for a human society. Different factors that influence masculinity among the Basotho as represented by Basotho accordion music artists are scrutinized to find out how masculinity as a thematic aspect in the development of Basotho accordion music has been manifested over a period of thirty-five years. Psycho-masculinity is employed in the present study to find out the impact of the existing form of masculinity among the Basotho. The study concludes that the present form of masculinity among the Basotho is precarious, not only to women and to children, but also to men in their two categories: those who exhibit masculinity as well as those who do not show evidence of it. Therefore, the study recommends that the Basotho masculinity should pay attention to the limitations of masculinity in order to minimize and consequently eradicate its negative side while simultaneously promoting its positive side towards men, women and children at large.Linguistics and Modern LanguagesD.

SMME access to finance in South Africa

The challenge of development in South Africa is to increase employment, broaden distribution of wages and enhance skills of all workers, but particularly those workers disadvantaged by apartheid. The high unemployment rate and unemployability of a large section of the population, self-employment through small business presents the only realistic solution. But successful start-up and sustainability of such enterprises requires readily available access to robust and effective microfinance and business support programmes. This research studied SMME access to state and commercial financing vehicles and how this impacted on their growth prospects. The results from case studies show pervasive lack of access to finance by the SMMEs and that business start-ups and cash flows are financed mainly from savings and, to a lesser extent, from simple instruments, such as bank overdraft; While these kinds of financing have led to increased stock carrying and modest revenue growths, it has led to neither expansion of business nor significant increases in employment. Although the results show that banks have made big strides in reaching out to previously excluded and unbanked consumers and that they are more visible to the SMME than state institutions, the business owners show high levels of risk and debt aversion by not taking advantage of available SMME focused loans offered by the banks. Albeit the study could not satisfactorily and authoratively establish causes of this aversion beyond information deficiency and incoordination within banks, it is clear that it (aversion) led to a form of self-censure to obtaining loans. More research is needed to get a better understanding of this phenomenon

Moral Values and Ethics as Antidotes for Corruption in the South African Public Service and Administration

This paper examines the relationship between morals, ethics, public administration and corruption. The argument advanced is that morals and ethics are antidotes for bureaucratic corruption in public service and administration. Currently there seems to be low ethics and morality in public service and administration in South Africa. The discussions in this paper consider the obligations under the South African National Development plan 2030, African Union Convention on Preventing and Combating Corruption, the African Charter on Values and Principles of Public Service and Administration, and the African Charter on the Values and Principles of Decentralization, Local Governance and Local Development for a corruption free and ethical public service and administration. https://doi.org/10.19108/KOERS.86.1.248

Manifestations of corruption in the City of Tshwane Metropolitan Municipality

This study was conducted as a result of the various media reports, various law enforcement investigation reports, Public Service Commission, reports of the Auditor General South Africa and the Public Protector South Africa on corruption and the various forms in which corruption manifests itself in the City of Tshwane Metropolitan Municipality and the effectiveness of the various law enforcement agencies and the government in tackling the scourge of corruption in public and private institutions. While South Africa has various anti-corruption strategies, they all seem to be ineffective and have thus far not achieved their desired results. A qualitative research approach was used to investigate this problem. A thorough literature study and documentary analysis was used to gather all the relevant data related to this topic. It has been found that the most common manifestations of corruption that take place in the South African public service are fraud, bribery, extortion, nepotism, conflict of interest, cronyism, favouritism, theft, graft, embezzlement and abuse of power. Other forms of corruption that raise concern are, for example, influence-peddling, insider trading/abuse of privileged information, bid-rigging and kickbacks. South Africa has, on the other hand, seven anti-corruption institutions and seventeen pieces of legislation which are intended to combat corruption in the public and private sector. These pieces of legislation give South African law enforcement and investigators in the public and private sectors a clear mandate with a view to investigating the high levels of corruption. It is the submission of the Public Service Commission (2011:vi) that corruption has become a global concern that seriously hampers development in any country and diverts its resources from where they are needed the most. The most unfortunate truth and reality about corruption is that the poor suffer the most.Criminology and Security ScienceM. Tech. (Forensic Investigation

Mitigating Group Bias in Federated Learning for Heterogeneous Devices

Federated Learning is emerging as a privacy-preserving model training approach in distributed edge applications. As such, most edge deployments are heterogeneous in nature i.e., their sensing capabilities and environments vary across deployments. This edge heterogeneity violates the independence and identical distribution (IID) property of local data across clients and produces biased global models i.e. models that contribute to unfair decision-making and discrimination against a particular community or a group. Existing bias mitigation techniques only focus on bias generated from label heterogeneity in non-IID data without accounting for domain variations due to feature heterogeneity and do not address global group-fairness property. Our work proposes a group-fair FL framework that minimizes group-bias while preserving privacy and without resource utilization overhead. Our main idea is to leverage average conditional probabilities to compute a cross-domain group \textit{importance weights} derived from heterogeneous training data to optimize the performance of the worst-performing group using a modified multiplicative weights update method. Additionally, we propose regularization techniques to minimize the difference between the worst and best-performing groups while making sure through our thresholding mechanism to strike a balance between bias reduction and group performance degradation. Our evaluation of human emotion recognition and image classification benchmarks assesses the fair decision-making of our framework in real-world heterogeneous settings

A fuzzy logic control system for a friction stir welding process

FSW is a welding technique invented and patented by The Welding Institute in 1991. This welding technique utilises the benefits of solid-state welding to materials regarded as difficult to weld by fusion processes. The productivity of the process was not optimised as the real-time dynamics of the material and tool changes were not considered. Furthermore, the process has a plastic weld region where no traditional modelling describing the interaction between the tool and work piece is available. Fuzzy logic technology is one of the artificial intelligent strategies used to improve the control of the dynamics of industrial processes. Fuzzy control was proposed as a viable solution to improve the productivity of the FSW process. The simulations indicated that FLC can use feed rate and welding speed to adaptively regulate the feed force and tool temperature respectively, irrespective of varying tool and material change. The simulations presented fuzzy logic technology to be robust enough to regulate FSW process in the absence of accurate mathematical models

Metallo-Graphene Nanocomposite Electrocatalytic Platform for the Determination of Toxic Metal Ions

A Nafion-Graphene (Nafion-G) nanocomposite solution in combination with an in situ plated mercury film electrode was used as a highly sensitive electrochemical platform for the determination of Zn2+, Cd2+, Pb2+ and Cu2+ in 0.1 M acetate buffer (pH 4.6) by square-wave anodic stripping voltammetry (SWASV). Various operational parameters such as deposition potential, deposition time and electrode rotation speed were optimized. The Nafion-G nanocomposite sensing platform exhibited improved sensitivity for metal ion detection, in addition to well defined, reproducible and sharp stripping signals. The linear calibration curves ranged from 1 μg L−1 to 7 μg L−1 for individual analysis. The detection limits (3σ blank/slope) obtained were 0.07 μg L−1 for Pb2+, Zn2+ and Cu2+ and 0.08 μg L−1 for Cd2+ at a deposition time of 120 s. For practical applications recovery studies was done by spiking test samples with known concentrations and comparing the results with inductively coupled plasma mass spectrometry (ICP-MS) analyses. This was followed by real sample analysis
