Abstract
Purpose
Sustainability principles have been practiced and researched in marketing for nearly five decades, but the challenges we face today are still significant. This context defines the purpose of this paper, which is to find, synthesize and critically evaluate the existing literature on marketing in a sustainability context from 1969 to 2019. The ultimate aim is to provide a unified body of literature on sustainability marketing and classify the extant literature.
Design/methodology/approach
The relevant articles from selected journals were identified and manually verified using the Scopus database. The SPAR- 4- SLR protocol provides the framework for the methodology. In total, 749 articles were eligible for inclusion in the study.
Findings
The research findings are presented in the form of article categorization into 11 thematic categories. The thematic categories outlined previous studies' trend and contribution characteristics under the individual category, illustrating their implications.
Practical implications
The literature review aids in understanding the current state of research and piques researchers' interest in sustainability marketing. The findings of the study will be a valuable resource for future scholars, managers and policymakers.
Originality/value
This study contributes to the existing literature by providing valuable insights from previous research on the research trend in sustainability marketing and by providing a recommendation for future research avenues. After a long hiatus, this is the most up-to-date comprehensive article, providing a general overview of research trends.

Abstract
Purpose
The purpose of this paper is to investigate the distinct reasons and more common reasons that reduce customer satisfaction and are antecedents to customer churn behavior in the telecommunication industry.
Design/methodology/approach
The study adopted the netnography approach to investigate churn behavior by utilizing online user-generated content in qualified social media communities.
Findings
The investigation revealed that “data speed issue”, “ineffective relationship building”, “service area coverage issues” and “billing issues” are some of the most important attributes that influence a consumers' decision to churn. Further, the churn consequence influencers model summarizes the attributes that contribute to overall dissatisfaction and finally results in churn behavior. The study found out the application of the netnography approach in a quantitatively dominant research area and stands out with its insights from a rich qualitative data.
Practical implications
Proper clarification of customer expectations and pain points can help reduce customer churn. The study will serve as the basis for developing future churn prediction models that will contribute to the informed decision-making process.
Originality/value
Contributing to research on customer churn behavior, the study offers a novel attempt to study customer satisfaction and customer churn behavior jointly. The paper is the first attempt that contributes to the extant literature by adopting the unique qualitative approach to understand the reasons for telecommunication churn behavior in the emerging Indian market. Another contribution of this research is that the paper shifts the focus of the electronic word-of-mouth (eWOM) literature to the telecommunications industry, thus adding another block to ongoing research in eWOM communication.

Abstract
Purpose
The purpose of this study is to analyze the thermal, hydraulic and entropy generation characteristics for laminar flow of water through a ribbed-wavy channel with the top wall as wavy and bottom wall as flat with ribs of three different geometries, namely, triangular, rectangular and semi-circular.
Design/methodology/approach
The finite element method-based numerical solver has been adopted to solve the governing transport equations.
Findings
A critical value of Reynolds number (Recri) is found beyond which, the average Nusselt number for the wavy or ribbed-wavy channel is more than that for a parallel plate channel and the value of Recri decreases with the increase in a number of ribs and for any given number of ribs, it is minimum for rectangular ribs. The performance factor (PF) sharply decreases with Reynolds number (Re) up to Re = 50 for all types of ribbed-wavy channels. For Re > 50, the change in PF with Re is gradual and decreases for all the ribbed cases and for the sinusoidal channel, it increases beyond Re = 100. The magnitude of PF strongly depends on the shape and number of ribs and Re. The relative magnitude of total entropy generation for different ribbed channels varies with Re and the number of ribs.
Practical implications
The findings of the present study are useful to design the economic heat exchanging devices.
Originality/value
The effects of shape and the number of ribs on the heat transfer performance and entropy generation have been investigated for the first time for the laminar flow regime. Also, the effects of shape and number of ribs on the flow and temperature fields and entropy generation have been investigated in detail.
