Background: The unprecedented and unchecked corruption practices that are prevalent in universities in South Africa have been aggravated by the minimal enforcement of policies and rules by university administrators and managers. This has opened up opportunities for corrupt relationships between internal and external stakeholders seeking to embark on corrupt activities in universities. As corruption is a worldwide phenomenon, this study selected previously disadvantaged universities in South Africa to investigate the effectiveness of university administrators and managers. The research examines the enforcement of policies and regulations in the effort to curb corruption.Objective: The study further sought to determine the extent to which service providers and politicians are enabled to manipulate the supply chain management and procurement systems, convincing the university officials to overlook quality standards and specifications.Method: This study was suited to a multi-case study approach, and the qualitative method was used to obtain data. A sample of 20 respondents were approached from different employment categories, including departments, faculties and trade unions.Results: The major highlights of the study pointed to the following as being the dimensions of corrupt practices in universities: rules and regulations were not enforced by university officials. There were obvious corrupt relationships and agreements among corrupt individuals, without any action being taken against them; there was a clear corrupt relationship between internal and external forces, which included bribery by funders, service providers and suppliers; there was political interference from members of management and council members, driving the corruption agenda.Conclusion: To fill the gaps that enable corruption in universities, the development of an anti-corruption workforce is a necessity. This can be achieved through skills development, proper intelligence, cooperation from stakeholders, employees refusing gifts and/or bribes and consequence management for those who are driving corruption.Contribution: The findings of the study can be used to assist university stakeholders, agencies and decision-makers in understanding the nature and extent of the corruption that is prevalent in the institutions concerned. The research could have a positive influence on improving policy compliance and adding value regarding the scant literature on corruption in universities.

Background: The current coronavirus disease 2019 (COVID-19) pandemic has stressed why a change towards resilient, robust and sustainable supply chains is more imperative than ever. This is especially true for supply chains of perishable foods, where issues such as the bullwhip effect cause not only economic but also environmental damage.Objectives: The key objectives of this study are to gain a deeper insight into correlations regarding the causes of the bullwhip effect and to see how a sinusoidal stimulus is affecting the generation of food waste.Method: A simplified beef food chain was modelled in Tecnomatix Plant Simulation®. As the bullwhip effect consists of a simplified parameterisation of an excitation duration (period length) and its height (amplitude), these two variables were used to generate a sinusoidal stimulus. The simulation results were statistically verified and checked for commonalities and differences with the already established scientific knowledge.Results: While the expected higher sensitivity of the front links of the supply chain to waste generation can be confirmed, the results of a long stimulation period suggest that the negative effects of the bullwhip effect do not increase indefinitely.Conclusion: The analysis of the results has shown that previous theories can be transferred, but that the variation of the variables entails new insights for the interdependencies of the amplitude and period length and their influence on the output variable waste.Contribution: The study contributes to a more holistic understanding of the bullwhip effect and, in particular, its implications within a perishable food supply chain.

Background: An effective and efficient last-mile delivery service plays a critical role towards the growth of global online retail sales. In Kenya, online customers have often been unwilling to shop online again, mainly because of delivery issues. However, the extent to which customers are satisfied with the last-mile delivery service remains unknown. This is despite the significant potential that the sector has, which remains unrealised in the country’s economy.Objectives: The key objective of this study was to establish the extent of customer satisfaction with the different elements of last-mile delivery service offered by online retailers in Kenya.Method: A quantitative approach was utilised. An online survey collected data from 467 online customers (‘users’ and ‘nonusers’) in Nairobi. The data were subjected to descriptive statistics and the mixed model analysis of variance (ANOVA) to determine the outcome of the study.Results: ‘Users’ were most satisfied with delivery options while ‘nonusers’ were most satisfied with delivery fees. However, both ‘users’ and ‘nonusers’ were least satisfied with returns. This study also found that ‘users’ were more satisfied with delivery options, delivery tracking and returns compared with ‘nonusers’. There was a significant difference in satisfaction with delivery options for ‘users’ and ‘nonusers’.Conclusion: Online retail managers are advised to improve the way in which they offer returns to their customers. This involves offering more options for returning the ordered goods, making it easy to locate the returns procedure on their websites and having a clear returns policy.Contribution: This study advances the understanding of last-mile delivery service, after comprehensive empirical evidence of customer satisfaction with the different elements of last-mile delivery service in Kenya.

Background: Air travel restrictions to prevent the spread of coronavirus disease 2019 (COVID-19) impacted air travel to and from and within South Africa significantly. The duration of the pandemic was more protracted than initially expected as new variants of the pandemic (in ‘waves') resulted in additional restrictions. Objectives: To determine the nature of COVID-19-related air travel restrictions, their impact on annual passenger demand, the number of flights operated (supply of services), the related average passenger loads carried as well as on tourism indicators of the direct contribution of travel and tourism, the total contribution to Gross Domestic Product (GDP) and employment. Method: The study identifies the number of passengers carried and flights operated and calculates the average passenger load per flight and trends. The impact on tourism indicators is based on the unit values of metrics published by the World Travel and Tourism Council for the 2019 calendar year, adapted for the reduction in passengers in the first and second years following the COVID-19 lockdown. Results: Significant decreases in the annual number of passengers carried, flights operated (in the three geographic areas), and their impact on tourism and employment indicators were identified. Conclusion: The decline in passengers exceeded the decrease in flights operated, which resulted in a decline in the average load of passengers carried per flight. The significance of COVID-19 restrictions on tourism indicators and employment was also calculated. Contribution: The study identifies the impact of COVID-19 air travel restrictions on both air transport and tourism indicators for South Africa.

Background: The business environment is increasingly becoming volatile, uncertain, complex and ambiguous (VUCA) because of globalisation, increased competition, random consumer tastes changes and environmental factors. Traditional procurement strategies are becoming increasingly redundant because of the volatility of the global business environment. The market has thus called for increased agility to conquer the VUCA nature of the supply chain environment.Objectives: The study sought to examine the role that e-procurement plays in augmenting the agility of supply chains. The four determinants of e-procurement, that is, e-design, e-sourcing, e-evaluation and e-negotiation, were linked directly with supply chain agility.Method: A census approach was taken to gather data from 219 supply chain and procurement employees of Zimbabwe’s telecommunications and technology industry. A self-administered survey questionnaire was used based on a scientifically developed and validated supply chain agility measurement scale from the extant literature.Results: Using structural equation modelling (SEM), the study’s results confirmed that e-procurement significantly predicts supply chain agility. All determinants of e-procurement were statistically significantly explaining supply chain agility in a volatile business environment.Conclusion: The study concludes that e-procurement augments the agility of the supply chain in volatile business environments, as e-procurement can increase swiftness and agility as it fosters ubiquitous business processes on a seamless real-time basis. It emerged from the study that the supply chain vulnerabilities volatile industries face could be eliminated through supply chain agility, augmented through e-procurement systems. The study’s findings also implore supply network members from upstream to downstream to adopt e-procurement.Contribution: The study has practical implications for all supply network members from upstream to downstream. It implores these members to adopt e-procurement to revive supply networks amid environmental volatility and alleviate miscommunication. Study also offers theoretical implications for e-procurement and supply chain management. The study also contributes to the body of knowledge by extending the existing theories on e-procurement and supply chains in the context of environmental volatility.

Background: Fruit is an important export commodity for South Africa and accounts for 35% of its agricultural exports. South Africa is the second largest citrus exporter in the world, behind Spain. Maintaining the postharvest cold chain is key to ensuring that fruit quality meets export standards.Objectives: The main objectives of this research were to investigate the frequency, location, magnitude and duration of temperature deviations in the South African leg of the clementine and navel orange cold chain.Method: Temperature trials were conducted on two consignments of clementines and two consignments of navels. Each consignment contained 36 iButtons®, of which 18 measured pulp temperature and 18 measured ambient temperature. Data were successfully retrieved from 130 of the 144 iButtons®.Results: This research identified areas where the temperature went outside the prescribed range along the South African portion of the export cold chain of navel oranges and clementines from Citrusdal, South Africa to the Port of Newark, United States of America.Conclusion: The temperature incidents identified could result in a breach of the cold sterilisation (steri) protocols and quality defects. Recommendations were made to address these deficiencies to improve the South African citrus industry’s global competitiveness.Contribution: This research allowed the citrus industry to investigate and adjust current cold chain practices to improve the integrity of the entire export cold chain, potentially resulting in a higher quality product and increased revenue.
