Abstract
Purpose
This paper aims to analyze and give directions for advancing research in stock market volatility highlighting its features, structural breaks and emerging developments. This study offers a platform to research the benchmark studies to know the research gap and give directions for extending future research.
Design/methodology/approach
The author has performed the literature review, and, reference checking as per the snowballing approach. Firstly, the author has started with outlining and simplifying the significance of the subject area, the review illustrating the various elements along with the research gaps and emphasizing the finding.
Findings
This work summarizes the studies covering the volatility, its properties and structural breaks on various aspects such as techniques applied, subareas and the markets. From the review’s analysis, no study has clarified the supremacy of any model because of the different market conditions, nature of data and methodological aspects. The outcome of this research work has delivered further magnitude to research the benchmark studies for the upcoming work on stock market volatility. This paper has also proposed the hybrid volatility models combining artificial intelligence with econometric techniques to detect noise, sudden changes and chaotic information easily.
Research limitations/implications
The author has taken the research papers from the scholarly journal published in the English language only and the author may also consider other nonscholarly or other language journals.
Originality/value
To the best of the author’s knowledge, this research work highlights an updated and more comprehensive framework examining the properties and demonstrating the contemporary developments in the field of stock market volatility.

Abstract
Purpose
The purpose of this paper is to study the interaction of main marine organisms on localized corrosion of 316L stainless steel in the Dalian Sea area.
Design/methodology/approach
The steel plate was immersed in the Dalian Sea area for nine months to observe the biofouling and localized corrosion. The local potential distribution on the steel plate covered by marine organisms was measured. The local electrochemical measurements were performed to facilitate understanding the interfacial status under different biofouling conditions. The local surface morphologies and corrosion products were characterized.
Findings
The localized corrosion of stainless steel is mainly induced by the attachment of barnacles on the steel. The mussels have no influence on the localized corrosion. The cover of sea squirts could mitigate the localized corrosion induced by barnacles. Both crevice corrosion and pitting corrosion were found beneath the barnacle without the covering of sea squirts. The pitting damage was more serious than the crevice corrosion in the Dalian Sea area. The probing of sulfur element indicates that the potential growth of sulfate-reducing bacteria at barnacle center.
Originality/value
The above findings revealed that the interaction of marine organisms has significant influences on the localized corrosion of stainless steel. The influences of macro-fouling and micro-fouling on localized corrosion are discussed.

Abstract
Purpose
The main purpose of this study is to explore different aspects of the Green Lean Six Sigma (GLSS) approach, application status and potential benefits from a comprehensive review of the literature and provide an avenue for future research work. This study also provides a conceptual framework for GLSS.
Design/methodology/approach
To do a systematic analysis of the literature, a systematic literature review methodology has been used in this research work. From the reputed databases, 140 articles were identified to explore hidden aspects of GLSS. Exploration of articles in different continents, year-wise, approach-wise and journal-wise was also done to find the execution status of GLSS.
Findings
This study depicts that GLSS implementation is increasing year by year, and it leads to considerable improvement in all dimensions of sustainability. Enablers, barriers, tools and potential benefits that foster the execution of GLSS in industrial organizations are also identified based on a systematic review of the literature.
Originality/value
The study’s uniqueness lies in that, to the best of the authors’ knowledge, this study is the first of its kind that depicts the execution status of GLSS, and its different facets, explores different available frameworks and provides avenues for potential research in this area for potential researchers and practitioners.

Abstract
Purpose
Evidence indicates that the Indian economy has grown enormously in recent years. and Lean Six Sigma (LSS) has evolved globally as a structured business improvement strategy with diverse applicability in the last fifteen years. Therefore, this paper aims to investigate the status of LSS implementation in Indian industries using a survey research technique.
Design/methodology/approach
A survey questionnaire was devised from the literature, containing 25 questions to assess respondents’ awareness of the LSS methodology and gain insights on aspects associated with LSS adoption in Indian industries. The survey questionnaire was validated and was conducted using randomly sampled respondents from the Confederation of Indian Industries membership database. The collected data were statistically analyzed using IBM SPSS and MS Excel.
Findings
The findings attest that adopting LSS is not so encouraging and extremely poor in small- and medium-scale Indian industries. ISO 9001 emerged as a prominent quality improvement program. It is learnt that consultants play a pivotal role in bringing awareness and skills building while implementing LSS. Results endorse top management commitment and involvement, and resistance to change as leading success factors and challenges, respectively. Further, it is revealed that respondents were highly satisfied after the adoption of LSS.
Research limitations/implications
The findings of this study were derived from 183 responses and should be generalized cautiously.
Originality/value
This paper provides valuable insights on the present status covering the issues related to L:SS implementation in India. These results can motivate the managers of Indian industries for wide adoption of the LSS methodology. In addition, the findings of the paper may assist the researchers providing direction to carry out further research in LSS in the Indian context.
