Beyond the Literature: a Comparative Analysis of Sustainability Benefits and Risks of Crowd Delivery Businesses in Research and Practice
(Elsevier, 2025) Gocer, Aysu; Izcan, Elif; Vural, Ceren Altuntas
Crowd delivery (CD) business provides an innovative service in managing the tension between delivery speed and cost, while providing work for individuals. While CD is recognized as a promising business in literature, consistently acknowledging its positive impacts on sustainability, real-world practices underscore the prominence of sustainability-related challenges related to managing CD volume, liability, security, trust, and environmental issues. This study aims to bridge this gap between research and practice in CD business sustainability by examining current practices against existing knowledge, investigating sustainability benefits and risks, and identifying discrepancies to understand the business's changing dynamics. In that respect, a multi-method approach is employed, combining systematic literature review (SLR) and semi-structured interviews. Comparative content analysis between research and field data identifies sustainability benefits and risks for CD businesses for environmental, social and economic dimensions and outlines different perspectives of academic studies and field data. This research sheds light on the evolving relationship between theoretical understanding and realworld implementation of the sustainability benefits and risks of CD business under four categories: (1) "research supported by practice", (2) "research/practice transformed", (3) "in practice only", and (4) "in literature only". These categories underscore the dynamic nature of sustainability in the context of CD businesses, demonstrating areas of convergence and divergence between research and practice and highlighting the need for ongoing development of theoretical frameworks to reflect real-world practices. The implications of this study have the potential to both guide academic research towards practical concerns and enable practitioners to improve CD business sustainability for all stakeholders.

Drivers of and Barriers Against Market Orientation: a Study of Turkish Container Ports
(Palgrave Macmillan Ltd, 2019) Gocer, Aysu; Vural, Ceren Altuntas; Deveci, Durmus Ali
Privatization transforms the operations-focused and stakeholder-independent approach of container port management into a competition and market-oriented perspective. This integrates a marketing philosophy with the management of the overall port organization. In this way, ports become more responsive to market demand and create profitable and sustainable customer value, so as to achieve competitive advantage. This change is caused both by the evolving port governance systems, as well as by changing market demand, requiring ports to respond to the needs of the supply chains they serve. An increasingly prevalent logistics perspective in maritime transport is accelerating pressure on ports and other members of service supply chains encouraging them to adopt market-oriented strategies. Accordingly, the purpose of this study is to discover both the drivers and the barriers that container ports face while adopting market-oriented strategies. Taking Turkish container ports as the main unit of analysis, this article combines the Delphi method with fuzzy analytic hierarchy processing to identify the prioritized opinions of industry stakeholders. The results indicate that customer relations are perceived to be very important for container ports, in terms of communicating value-added services, and even more important than economic concerns or possessing market knowledge. Often, however, ports define their customers within a limited scope, and fail to adopt a supply chain perspective. Therefore, new strategies, such as market resegmentation including support service providers, or evaluating end-customer demands by analyzing supply chains that include port services, should be developed to eliminate the prioritized barriers. Drivers, such as collecting market information, or building market-oriented teams, can be used more effectively to make market orientation a new competition tool for all ports. Finally, our results provide new variables to scholars studying port marketing and put forward recommendations for testing the relationships between these variables.

Looking Inside the Panarchy: Reorganisation Capabilities for Food Supply Chain Resilience Against Geopolitical Crises
(Emerald Group Publishing Ltd, 2024) Vural, Ceren Altuntas; Balci, Gokcay; Surucu Balci, Ebru; Gocer, Aysu; Altuntas Vural, Ceren
PurposeDrawing on panarchy theory and adaptive cycles, this study aims to investigate the role of reorganisation capabilities on firms' supply chain resilience. The conceptual model underpinned by panarchy theory is tested in the agrifood supply chains disrupted by a geopolitical crisis and faced with material shortage. The study considers circularity as a core reorganisational capability and measures its interplay with two other capabilities: new product development and resource reconfiguration capabilities to achieve supply chain resilience.Design/methodology/approachA quantitative research design is followed to test the relationships between circularity capabilities, resource reconfiguration capabilities, new product development capabilities and supply chain resilience. A cross-sectional survey is applied to a sample drawn from food manufacturers who are dependent on wheat and sunflower oil as raw material and who are faced with material shortages in the aftermath of a geopolitical crisis. Measurement models and hypotheses are tested with the partial least squared structural equation modelling (PLS-SEM) based on 324 responses.FindingsThe results show that new product development and resource reconfiguration capabilities fully mediate the relationship between circularity capabilities and supply chain resilience. In other words, the food producers achieved supply chain resilience in response to agrifood supply chain disruption when they mobilised circularity capabilities in combination with new product development and resource reconfiguration capabilities.Practical implicationsThe findings suggest that producers in the agrifood industry and even those in other industries need to develop circularity capabilities in combination with new product development and resource reconfiguration capabilities to tackle supply chain disruptions. In a world that is challenged by geopolitical and climate-related crises, this means leveraging 3R practices as well as resource substitution and reconfiguration in new product development processes.Originality/valueThe study explores the release and reorganisation phases of adaptive cycles in a panarchy by analysing the interplay between different capabilities for building supply chain resilience in response to disruptions challenging supply chains from higher levels of the panarchy. The results extend the theoretical debate between circularity and supply chain resilience to an empirical setting and suggest the introduction of new variables to this relationship.

Value co-creation in maritime logistics networks: A service triad perspective
(Elsevier Sci Ltd, 2019) Vural, Ceren Altuntas; Gocer, Aysu; Halldorsson, Arni
Maritime logistics networks face several challenges in the supply chains they serve. Tackling those challenges requires a perspective of treating value as a co-creation through interactions amongst the key actors in the maritime logistics sector. By adopting a triadic approach, this paper explores how maritime logistics value is cocreated in the service triad composed of the shipper, the logistics service provider (LSP), and the carrier (that is, the shipping line). Based on the service-dominant logic, this study identifies a number of operant resources and investigates various configurations of operant resources amongst these three players in the maritime logistics service triad. The results provide guidance for policymakers as well as firm-level decision-makers who must take an integrative approach to capture the multi-actor nature of the phenomenon. The findings may help managers understand how operationalization of their policies and decisions may affect both the type of operant resources used for value creation as well as their interdependence. Finally, studying maritime logistics value with a network approach offers opportunities for research on value and interaction between supply and transport service networks.
