{"title":"Identifying temperature deviations in the hake cold chain from Namibia to Spain","authors":"Chelna Neethling, Leila L. Goedhals-Gerber","doi":"10.4102/jtscm.v17i0.923","DOIUrl":"https://doi.org/10.4102/jtscm.v17i0.923","url":null,"abstract":"Background: Research shows that significant volumes of fresh fish produced globally are wasted because of failures in the cold chain. As fresh hake is extremely temperature sensitive, fluctuations in temperature will influence the quality and the shelf life, resulting in losses in revenue. Objective: The main objective of the research was to detect deviations in temperature along the fresh hake export cold chain from Namibia to Spain. Method: This article presents a case study on a company that exports fresh hake from Walvis Bay, Namibia to a large supermarket chain in Spain, Europe. Results: This article confirms that temperature breaches and breaks occur and are sometimes unavoidable. However, if the avoidable temperature deviations could be resolved, it would improve both the effectiveness and efficiency of the export cold chain. The results indicate that temperature breaches and breaks mainly occur along the export cold chain when the product is at the airport during transfer flights either at Hosea Kutako Airport near Windhoek or Frankfurt Airport in Germany or in the refrigerated truck during the inland transport leg either from Walvis Bay, Namibia or Frankfurt, Germany to Zaragoza, Spain. Conclusion: This article makes recommendations to assist in solving identified problems and streamlining the fresh hake export cold chain. The research benefits the Namibian fishing industry as the export of fresh fish is both a precarious and taxing venture. As relevant research is lacking in Namibia, this article will contribute to the management of an efficient and effective export cold chain. Contribution: This research adds to the current knowledge of maintaining the export cold chain of fresh fish from developing countries. Preventing temperature deviations in the fresh hake export cold chain would extend the shelf life and help to maintain the quality of the fresh product and in so doing improve the competitiveness of developing countries in the global trade of fresh fish.","PeriodicalId":43985,"journal":{"name":"Journal of Transport and Supply Chain Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136062228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Managing omni-channel reverse logistics risk during supply chain disruption recovery in the South African fashion industry","authors":"Tristan Ermes, Wesley Niemann","doi":"10.4102/jtscm.v17i0.932","DOIUrl":"https://doi.org/10.4102/jtscm.v17i0.932","url":null,"abstract":"Background: Omni-channel retailing is blurring the lines between online and physical stores for consumers as it provides consumers with more choices, convenience and a seamless shopping experience. An integral aspect of implementing an omni-channel retail strategy is having an efficient reverse logistics process. However, retailers seem reluctant to implement omni-channel reverse logistics because of the various risk types that affect the economic wellbeing of a firm, especially during supply chain disruption recovery (SCDR) when the firm is in distress. Prior research primarily examines the risks associated with reverse logistics in a single channel. While the existing findings are promising, there is a lack of understanding regarding the specific risks involved in omni-channel reverse logistics and how to mitigate these risks in the context of SCDR.Objectives: The purpose of this study was to explore omni-channel reverse logistics risks and mitigation strategies during SCDR in the South African fashion retail industry.Method: The study employed a generic qualitative design using purposive sampling methods. Fourteen semi-structured interviews were conducted to collect data. The data were analysed using a thematic analysis approach.Results: The study identified specific types of omni-channel reverse logistics risks. The findings indicate that omni-channel reverse logistics risk during SCDR is managed through proactive and reactive strategies such as technology implementation, collaborative relationships, quality insurance inspections, customised policy changes and disruption-specific reverse logistics teams. The findings show that mitigating omni-channel reverse logistics risk can help create a competitive advantage because of increasing customer loyalty, value recovery and profits.Conclusion: The findings provide valuable insight on how to manage omni-channel reverse logistics risk during SCDR and, if mitigated correctly, can contribute to a competitive advantage.Contribution: This study expands on the current literature by identifying multiple types of omni-channel reverse logistics risks and strategies used to manage omni-channel reverse logistics risk in a SCDR context.","PeriodicalId":43985,"journal":{"name":"Journal of Transport and Supply Chain Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136023782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While normally encountered in supply chain management literature as discourse on supply chain effectiveness, this study shows that in a Fourth Industrial Revolution (4IR) world, the role of collaboration needs to be re-examined.Objectives: To understand how technology has enabled collaboration between companies to the extent that a collaboration should be viewed as an external business environmental factor.Method: A qualitative, grounded theory approach was followed. Semi-structured interviews were conducted with 14 senior managers of a global technology-driven company manufacturing electrical heat tracing systems. Data were analysed using a three-stage coding process to develop an essential narrative.Results: Technology has presented new possibilities for collaboration across supply chains and industries. This results in co-creation of product offerings between companies opening new markets. Collaboration is no longer only an internal tool that can facilitate efficiency and effectiveness between collaborating partners but spills over as an influence on strategy from the external environment.Conclusion: If a collaborative climate is not nurtured and supported by all parties involved, a business will not be able to reach its full potential especially in a 4IR world. Advances in technology have enabled new possibilities for companies to collaborate, both internally and with each other.Contribution: Literature rarely extends the value of collaboration beyond the realm of the supply chain. This paper suggests that by viewing it as a macro-environmental factor, collaboration can be viewed as a strategic opportunity.","PeriodicalId":43985,"journal":{"name":"Journal of Transport and Supply Chain Management","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85518711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A lack of investment in marine services capacity and performance in South African ports remains a concern for port users and supply chain practitioners.Objectives: This study examines the capacity and performance of marine services in South Africa’s ports. The primary example examines marine services performance data for the Port of Durban.Method: This study uses Transnet National Ports Authority (TNPA) data and descriptive statistics to analyse marine fleet performance, bollard pulls and human capacity in South Africa’s ports to identify causes of shipping delays in the Port of Durban from 2014 to 2021.Results: The 8 years analysis show five most prominent sources of shipping delays in Ports as; tugboats occupied, shift changes, shipping movements, tugs out of commission and adverse weather conditions. Other factors identified were pilot-boat availability, overbooking slots, port meetings, etc. The performance of marine services are impacted by outdated wet infrastructure and a shortage of marine crafts and critical skills.Conclusion: There is a clear and justified need to increase physical and human capital investment in the provision of marine services and improve maintenance spending on critical infrastructure to reduce shipping delays and costs of conducting trade in South African (SA) ports.Contribution: The study compiles, analyses and provides a contextual understanding of the number of marine crafts, average bollard pulls, human resources capacity and causes of shipping delays in Republic of South Africa (RSA) ports.","PeriodicalId":43985,"journal":{"name":"Journal of Transport and Supply Chain Management","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87261328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ngcamu, Evangelos Mantzaris","doi":"10.4102/jtscm.v17i0.814","DOIUrl":"https://doi.org/10.4102/jtscm.v17i0.814","url":null,"abstract":"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.","PeriodicalId":43985,"journal":{"name":"Journal of Transport and Supply Chain Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135239687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":43985,"journal":{"name":"Journal of Transport and Supply Chain Management","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80622336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
