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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The view that supply chain learning (SCL) has become a fundamental capability that supply chains must employ to innovate and improve their financial, technological, operational, environmental and social performance is widely accepted. However, the SCL phenomenon is still understudied and not fully understood by scholars, decision-makers and government representatives. This article aims to make sense of the existing literature and to identify important research directions that require further attention.

This article reviews the diversity of SCL in the literature, proposes a typology of such a phenomenon, provides an overview of key articles in the literature and identifies a series of recommendations for the future development of the field.

This article combines two fundamental dimensions from the literature (i.e. SCL driver and SCL network) to produce a typology of four types of SCL: Captive, Consortium, Selective and Distributed.

The typology proposed here offers an important framework for supply chain decision-makers to rely on when implementing SCL initiatives. The implications of each type of SCL offer a robust rationale for decision-makers to adopt the most appropriate type of SCL or combinations of SCL types, given each situation. In addition, the typology supports policy-makers in further understanding the SCL phenomenon and creating effective innovation, economic development and sustainability policies through supply chains.

This article offers a novel typology that the authors hope will help scholars to advance the field of SCL in order to understand this important phenomenon. There is no good/bad/better/worse SCL type in the proposed typology, but the critical element for the success of SCL efforts is the level of fit between the type of SCL, the type of knowledge to be created and diffused, and the outcome supply chains aim to achieve with that learning effort. In addition, the authors coin the construct of “the learning supply chain”, which refers to a supply chain that learns constantly by employing all four types of SCL simultaneously.

This paper aims to investigate the main associations between research regarding innovation and green supply chain management (GSCM).

For this the study sought to (1) present the most cited authors in the area; (2) demonstrate the main localities that develop research with this focus; (3) list the main journals with the published research on the themes. The methodology used was a bibliometric survey using the Scopus database as the data source. The VOSviewer® software was used to perform the analysis of the database from the respective DOI® of each article.

As results of the research, it is possible to demonstrate the existence of an agglomeration of countries that are interrelated in the development of research on these themes, especially China, the United States and the United Kingdom as the main foundations of this center.

This paper evidences the direction of scientific research within the analyzed area, demonstrating where there is convergence for innovation in actions related to GSCM. This guidance may demonstrate possible existing and unexplored gaps so that researchers can direct future research or check gaps to be filled by the development of new processes.

This paper is an excerpt from a countrywide study entitled “Leisure in Brazil: representations and realizations of daily experiences”, which aims to investigate what Brazilians do in their leisure time, what they would like to do and why they do not do it.

Specifically, in this paper, the authors analyze data referring to the elderly population from southeastern Brazil. Sampling of the national survey comprised representative quotas of the population, considering region and state, and, in each state, quotas of sex, age, education level and family income, according to data obtained by IBGE in 2010. A total of 2,400 interviews were conducted in total. For the present study, the 91 interviews conducted with elderly subjects from the Southeast region of Brazil were considered.

The majority of participants understand leisure as a time for resting and fun and have physical/sports interests as their favorite leisure activity during the week. On weekends, social and tourism interests stand out, and idleness stands out in the preference of this public during the holiday period. Lack of time and financial resources are the main barriers to the access to and permanence in the desired leisure practices.

Having knowledge of the relationship between leisure and aging in Brazil is a way to contribute to the potential of this stage of life, based on the quality of life and continued learning provided by the content they enjoy.

The study aims to explore the argument of implementing the lean method to part or whole of an operation by examining the moderating impact of varying levels of the extent of implementation of four different lean methods, along with their functionalities, in predicting productivity improvement (PI).

As the focus of understanding the efficacy of lean principles is shifting from process to industry level, this study tried to generalize the approach by gathering data from 132 large Indian auto component manufacturers. This involves an assessing/monitoring approach rather than measurement.

Results highlighted the interdependence or individuality of the extent of implementation of lean methods and their functionalities. Findings revealed a significant moderating effect in improving productivity to a greater extent of 50%.

Adopting an assessment approach to a measurement study provides a noteworthy contribution to bridging theory and practical consequences. The findings can be appropriately extrapolated to medium and small enterprises forming a critical connection in the entire automobile manufacturing ecosystem.

The study showed that even if a lean method is applied to a certain extent of operations the chances of PI are significant. This is important for decision makers as they confront problems of optimum resource allocation.

PI, reduced cost and generalization of results would enable the auto component industry to become more competitive.

The examination of the moderation effect of a lean principle implementation extent, along with that of its functionalities to predict the improvement in productivity from its existing level, is a major outcome of this study.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

This study aims to discuss the influences of green innovation processes on sustainable development and proposes a research model linking green absorptive capacity, green dynamic capabilities and green service innovation with the aim of clarifying how these interactions operate within universities.

Supported by a survey of sustainability researchers in Brazilian universities, a mediation‐moderation analysis and partial least squares structural equation modelling approach is used to examine the influence of green absorptive capacity and green dynamic capabilities on green service innovation.

This study reinforces that greening processes and products are relevant to an organization and provide information on the mechanisms for achieving greater sustainable performance.

Considering one of the dimensions of administrative science as being university management, this study provides information on the mechanisms to achieve better sustainable development in universities.

This study contributes to the debate by adding the perception of university managers and provides guidance on new forms of management, which allows them to face changes while minimizing the disruption to the formation of organizational knowledge.

Universities are becoming increasingly active in promoting societal changes toward sustainable development. It is intended that the results of this research contribute to future research and act as a reference for researchers, professionals and policymakers.

The concept of green absorption capacity in universities is relatively new and has not yet been investigated completely with respect to its association with university management and organizational structures.
