Background: Contemporary economic systems are characterised by the increasing volumes and flow of goods. This attribute highlights the importance of logistics wherein one of the key focus areas pertains to the movement and storage of freight at different geographical scales.Objective: In the light of the importance of theory in research as well as the significance of geographical location in logistics processes, the objective of the paper is to analyse the extent, scope and gaps of theory utilisation in logistics-related research.Method: The paper is based on a systematic literature review approach that encompassed 243 sources. The searches were conducted on the Internet database platforms using keywords such as logistics, logistics activities, geography of logistics activities, supply chain management, logistics theories and freight models.Results: The relationship between logistics research and theory is ambiguous in that the majority of the research does not explicitly incorporate theory. Logistics particularly benefits from theory originating from other disciplines, such as economics, strategic management and marketing; however, the use of theories that originate from human geography has been limited in logistics research.Conclusion: The drive to understand the movement and storage of freight at different scales has relevance to human geography, particularly the subdisciplines of transport geography and economic geography. It is therefore recommended that logistics research consider the theoretical frameworks originating from human geography.

Background: Nowadays, a gradual change in customers’ attitudes towards transport service makes it more challenging to understand the reasons behind customers’ travel decisions. High-speed rail (HSR) has been mentioned recently and is expected as the best and most modern transport option in long-distance trips in Vietnam. However, research studies have paid scant regard to how HSR’s attributes may affect potential users, and therefore the motivations and barriers to adopting HSR are still unknown. Objectives: This study aimed at examining motivations and barriers to take-up HSR for considering customers’ preference on the proper attributes and levels of HSR. Method: This study drew on a nationwide survey and conjoint analysis to investigate customers’ behaviour. Results: In Vietnam’s context, HSR ticket was found to be the principal barrier to adoption, whereas the speed of HSR was identified as the least important behavioural driver amongst potential HSR users. The results show that HSR design and planning should provide a combination of minimum check-in and waiting time, a 20-min frequency, average speed of 250 km/h, all add-on services and facilities, ticketing of approximately VND 500–700 thousand per 300–500 km and nearby all-day parking. Conclusion: This investigation has demonstrated the value of conjoint analysis to compare a wide range of attributes associated with consumers’ decision to use HSR. The findings indicate that in countries such as Vietnam, in particular, where train usage is low, policymakers and transportation agencies seeking to boost the use of HSR must take attributes other than fare into consideration.

Background: After coronavirus disease 2019 (COVID-19) was declared a pandemic, movement restrictions were implemented across sub-Saharan Africa. There has been much speculation on what the long-term impacts on urban transport might be. Objectives: The aim of this paper is to identify the revealed and future travel impacts of the pandemic. Method: To pursue this aim, evidence was compiled from two sources: secondary big data;and a ( n = 15) two-wave Delphi panel survey of experts in the region. Results: It is predicted that longer-term impacts will take the form of: reduced travel by, and accessibility for, low-income households residing in peripheral locations because of decreased welfare;reduced transport service availability;operator reduction (particularly amongst unsubsidised formal operators);increased remote activity participation for a minority of better resourced households with white-collar workers;and disrupted trip distributions as the mix of city-centre land use changes in response to business attrition in economic recession rather than to disrupted bid rents. Conclusion: The major impact of the pandemic is likely to be on welfare, rather than on trip substitution. There is a need, therefore, to focus policy on the mitigation of these impacts and, more particularly, on ways of measuring changes in transport disadvantage and exclusion so that reliable data are available to inform mitigation strategies. The mitigation strategies considered should include investment in affordable ‘digital connectivity’ as a means of complementing accessibility from physical proximity and mobility. The pandemic also highlights the need to develop more robust transport planning practices to deal with uncertainty.

Background: In the previous two decades, preferential procurement and supply chain performance have gained popularity within academics following the introduction of the Preferential Procurement Policy Framework Act No 05 of 2000 (PPPFA) which was aimed at providing opportunities in government supply chain contracts to previously disadvantaged groups. Despite PPPFA being a corrective measure, research has brought to light the abuse and manipulation in the implementation of this Act by government officials trusted with this function. The study aims to determine how supply chain performance is affected by preferential procurement within selected Gauteng government departments.Objectives: The objectives of the study were twofold: First to determine how supply chain performance is influenced by preferential procurement and the effect of management levels on the implementation of PPPFA, and secondly to determine the effect of the implementation of preferential procurement on supply chain performance within selected government departments.Method: Through a quantitative research approach, data were collected using close-ended questionnaires in the form of a five-point Likert scale and a stratified random sampling technique. The Statistical Package for the Social Sciences (SPSS) software was used to analyse data through descriptive and inferential statistics.Results and conclusion: The study revealed that preferential procurement had an impact on supply chain performance in the selected departments which could be pinned mainly to the gap between policies and implementation. Although preferential procurement was generally applied across the departments, it was noted that some officials within supply chain management had not fully understood the implementation requirements of the PPPFA.
