What encourages people to carpool? A conceptual framework of carpooling psychological factors and research propositions

Carpooling brings benefits to carpool participants and the environment and society. Literature has called for a better understanding of psychological factors encouraging people to carpool however current research does not provide an in-depth psychological understanding of carpooling behaviour. This paper provides a review of psychological factors motivating drivers and passengers to carpool and identifies psychological theories appropriate for carpooling research. The Theory of Planned Behaviour and Norm-Activation Model were used as a priori theoretical frameworks to undertake a systematic literature review to identify important factors and relevant theories. Eighteen psychological factors were identified and classified as either common for drivers and passengers or specific to each group. In addition to the a priori frameworks, Consumer Perceived Value, Social Capital, and Technology Acceptance Model are considered the most appropriate for carpooling research. A conceptual framework and six research propositions were developed. Further, eight additional directions for future research were suggested including employing a variety of data collection methods to ensure rigour; collecting more data from non-Western countries for contextual veracity; exploring and testing psychological factors more deeply; and investigating the impact of COVID-19 on carpooling decisions. This paper contributes to theory through the development of the conceptual framework and identifying research propositions and providing additional research directions. Practically, the identified factors can be considered by researchers, matching agencies, and policy-makers to better promote carpooling

Developing and validating a national logistics cost in Thailand

National logistics cost can be used as a key indicator to reflect a country's overall logistics performance and monitor their respective logistics policies. However, not all countries have developed this indicator, and some have used differing methodologies. This paper provides an approach for calculating national logistics cost per gross domestic product (NLC/GDP) in the context of Thailand and demonstrates its veracity and validity using an action research methodology with key stakeholders. The approach utilizes easily obtainable macro level data combined with survey data. The calculation method has progressively improved in its accuracy and efficacy to reflect Thailand's logistic context. The proposed approach contributes to the national logistics cost debate and can inform academics, managers, and policy makers not just in Thailand but, in other countries when developing their own NLC/GDP to evaluate their respective logistics development activities.peerReviewe

Investigating the impact of the strength of supply chain integration on cost and responsiveness

The purpose of this paper is to investigate strength of supply chain integration based on social exchange theory and its resultant impact on supply chain cost and responsiveness. The study surveyed Korean export firms and obtained 182 usable responses. Data were analysed using cluster analysis and analysis of variance. Findings confirm that the strength of supply chain integration provides a mechanism for measuring the width of integration for both suppliers and customers. Further, identifiable gaps in cost performance and responsiveness were found based on strength of supply chain integration. This paper contributes through the development and testing of a conceptual model based on social exchange theory and also offers managerial suggestions in the understanding of customer needs and the importance of sharing information with suppliers in achieving improved cost performance and responsiveness in the supply chain.peerReviewe

A systematic review of humanitarian operations, humanitarian logistics and humanitarian supply chain performance literature 2005 to 2016

© 2017, Springer Science+Business Media New York. The purpose of this manuscript is to explore methodologies for conducting comprehensive literature review. The manuscript objectives are twofold: one is to identify a suitable methodology for conducting comprehensive literature review and two is to enable the identification of main research themes and clusters obtained from the literature. The domain of humanitarian operations, logistics and supply chain performance is selected as the review context. The main strength of a systematic literature review from other styles of literature review is that it provides a much higher level of methodology to the process. It further provides a rapid comprehensive identification of main research themes and clusters as illustrated from the humanitarian operations and logistics performance domain
