Abstract

Purpose

This paper explores how organizational capabilities and path dependence affect the implementation of supply chain (SC) sustainability initiatives. Through the lenses of contingency and evolutionary theory, the paper addresses the underexplored supply chain dynamics that enhance or inhibit sustainability trajectories.

Design/methodology/approach

Using in-depth multi-case studies for theory elaboration, five supply chains were studied through open-ended interviews with SC members, secondary data collection and site visit observation. The design consists of a combination of deductive and inductive approaches to elaborate theory on supply chain dynamics and enhanced sustainability trajectories.

Findings

The empirical study shows that learning is a fundamental condition for supply chains as they implement sustainability initiatives, and that exploitation capabilities are more frequently used than exploration capabilities. Path dependence plays a role in the outcomes of supply chain sustainability initiatives, which are influenced by both path dependence and contingencies of the contexts in which these systems operate.

Research limitations/implications

This paper puts forward five propositions that emerge from the literature and from the field study results. Although this is an exploratory research bounded by geographical limitations and the limited number of SC cases, the goal of elaborating theory may open up several promising avenues for future large-scale and longitudinal research studies.

Practical implications

By enhancing our understanding of the dynamics of supply chain sustainability trajectories, decision-makers, scholars and policy-makers can better understand how supply chains learn, how they employ SC member capabilities and how they deal with stakeholder resistance.

Originality/value

This paper extends supply chain sustainability theory by addressing the knowledge gap that exists with regard to understanding the dynamics of evolving supply chain sustainability trajectories. This paper sheds additional light on this important topic and contributes in multiple ways to the sustainable supply chain management literature.

Abstract

Purpose

A growing number of private, voluntary and mandatory sustainability standards have recently emerged. However, supply chain corruption practices as mechanisms to circumvent sustainability standards have also grown and occur regularly. This paper strives to elaborate theory on the intersection of institutional theory, business corruption and the sustainability standards literature by investigating factors that influence the emergence of supply chain corruption practices.

Design/methodology/approach

Based on secondary data, four in-depth case studies of supply chain corruption practices are investigated through the use of adaptive theory and the method of constant comparisons to elaborate theory on this important phenomenon.

Findings

The paper suggests that although sustainability standards can improve supply chain sustainability performance, if they are adopted only symbolically and not substantively, unanticipated outcomes such as supply chain corruption may occur. The study proposes a typology of supply chain corruption practices, further explores the symbolic adoption of sustainability standards in supply chains and proposes the novel construct of “social isomorphism for corruption.” Since focal companies play central roles in leading supply chain corruption practices, we reason that they can also play a pivotal role in preventing supply chain corruption practices by promoting the substantive adoption of sustainability standards across their supply chains.

Originality/value

This paper elaborates theory on the challenging phenomenon of corruption in supply chains by linking the supply chain management literature to the corruption and the sustainability discourses and offers important insights to aid our understanding on the topic. It generates six propositions and four contributions to the sustainable supply chain management theory, practice and policy.

Abstract

Purpose

This paper is devoted to the question of what motivates man in his pursuit of economic activities. Particular attention is given to the notion that economic activities of individuals may not be motivated by their self‐interest alone.

Design/methodology/approach

Using literary analysis, the paper first reconsiders the role of self‐interest and non‐selfish motives in the historical schools. Then it is demonstrated that at least some non‐selfish motives were incorporated in the voluntary exchange theory of public economy. Next it is shown that during the evolution of the theory of public goods these non‐selfish motives were lost and that the modern theory of public goods rests entirely on the self‐interest hypothesis. However, over the last two decades results of public goods experiments have cast considerable doubt on the pure self‐interest hypothesis.

Findings

A major finding of this paper is that several non‐selfish motives of man that show up in recent public goods experiments were already discussed by representatives of the historical schools.

Research limitations/implications

An agenda for future research on the topic is sketched in the final section.

Practical implications

Practical implications include that the allocation of many goods, not just public goods, may improve if agents pay more attention to non‐selfish motives of man.

Originality/value

The paper adds to the existing body of related writings by linking developments in the evolution of theory of public goods, in particular recent findings from public goods experiments, to a specific aspect already advocated by representatives of the historical schools, that is, the notion that man in his pursuit of economic activities is not motivated by his self‐interest alone. To this extent, the paper is of interest for researchers working on public goods theory, experimental economics and the history of economic thought.

Abstract

Purpose

User-generated content and online reviews are highly relevant in purchase decision in the hospitality sector, including restaurants, but there is a lack of knowledge about the effect of sharing pictures in this context. This study aims to focus on the relevance of user-generated photos in online platforms for restaurants’ selection.

Design/methodology/approach

A research was conducted with a sample of 319 residents of Porto region, who had at least one meal in a restaurant over the 30 days before the answer of the survey and had searched online to select the restaurant.

Findings

The results show that while doing online research about restaurants, it is important for potential consumers to find pictures of food and physical evidences of restaurants generated by other users. Findings also show that consumers find user-generated photos especially at websites of reviews, although the importance of restaurant owned platforms, such as official social media pages and websites.

Practical implications

The research results appeal restaurant managers to understand the importance of user-generated photos in online platforms by promoting photo sharing in their restaurants with appropriate marketing activities for that purpose.

Originality/value

This paper expands the state-of-the-art about the importance of user-generated content, focusing on the importance of photos from restaurants shared by consumers in online platforms.

Abstract

Purpose

This paper aims to develop a capacitor position in radial distribution networks with a specific end goal to enhance the voltage profile, diminish the genuine power misfortune and accomplish temperate sparing. The issue of the capacitor situation in electric appropriation systems incorporates augmenting vitality and peak power loss by technique for capacitor establishments.

Design/methodology/approach

This paper proposes a novel strategy using rough thinking to pick reasonable applicant hubs in a dissemination structure for capacitor situation. Voltages and power loss reduction indices of distribution networks hubs are shown by fuzzy enrollment capacities.

Findings

A fuzzy expert system containing a course of action of heuristic rules is then used to ascertain the capacitor position appropriateness of each hub in the circulation structure. The sizing of capacitor is solved by using hybrid artificial bee colony–cuckoo search optimization.

Practical implications

Finally, a short-term load forecasting based on artificial neural network is evaluated for predicting the size of the capacitor for future loads. The proposed capacitor allocation is implemented on 69-node radial distribution network as well as 34-node radial distribution network and the results are evaluated.

Originality/value

Simulation results show that the proposed method has reduced the overall losses of the system compared with existing approaches.

Abstract

Purpose

The purpose of this paper is to detail an actor-network theory inspired ethnography of recording heritage buildings. The case study focusses on Irbid School in Al Tal area, which is one of the oldest schools in Jordan and an important heritage building.

Design/methodology/approach

The recording process was undertaken by third-year architectural design studio students from Philadelphia University. The paper documents the interaction between the heritage building and the students in a two-phased ethnography, including fieldwork conducted between September and December 2017.

Findings

The paper proposes the concept of “transfer ethnography”, which considers the continuous changes in design across different locations. This extends beyond traditional ethnography, which focusses on a single location. Here, in contrast to the classical viewpoint, following the recording process shows that building design is ongoing and extends beyond implementation through the years as the building ages.

Research limitations/implications

Due to the chosen research approach, the research investigated the most relevant events from the author’s perspective, which might extend in various ways. Future research is encouraged to investigate more events that support the empirical findings.

Practical implications

The paper provides a new angle from which building design networks can be followed through the transfer ethnography, which has implications for the recording and similar processes that necessitate the continuous following of actors.

Originality/value

The research suggests the transfer ethnography, which entails close and in-depth engagement with actors but changes with the transformation of a design while following the actors and networks’ shifts between the different locations. It is more delicate, attentive and indispensable considering the dynamics of design.
