Abstract
Purpose
This study aim to use the finite volume method to solve differential equations related to three-dimensional simulation of a solar collector. Modeling is done using ANSYS-fluent software program. The investigation is done for a photovoltaic (PV) solar cell, with the dimension of 394 × 84 mm2, which is the aluminum type and receives the constant heat flux of 800 W.m−2. Water is also used as the working fluid, and the Reynolds number is 500.
Design/methodology/approach
In the present study, the effect of fluid flow path on the thermal, electrical and fluid flow characteristics of a PV thermal (PVT) collector is investigated. Three alternatives for flow paths, namely, direct, curved and spiral for coolant flow, are considered, and a numerical model to simulate the system performance is developed.
Findings
The results show that the highest efficiency is achieved by the solar cell with a curved fluid flow path. Additionally, it is found that the curved path’s efficiency is 0.8% and 0.5% higher than that of direct and spiral paths, respectively. Moreover, the highest pressure drop occurs in the curved microchannel route, with around 260 kPa, which is 2% and 5% more than the pressure drop of spiral and direct.
Originality/value
To the best of the authors’ knowledge, there has been no study that investigates numerically heat transfer, fluid flow and electrical performance of a PV solar thermal cell, simultaneously. Moreover, the effect of the microchannel routes which are considered for water flow has not been considered by researchers so far. Taking all the mentioned points into account, in this study, numerical analysis on the effect of different microchannel paths on the performance of a PVT solar collector is carried. The investigation is conducted for the Reynolds number of 500.

Abstract
The environmental performance of organizations has come under public policy limelight since the phenomenal increase of natural resource degradation and industrial waste. Thus, green concepts have been put forward, but the implementation of green practices faces many barriers and challenges. These barriers require attention as organizational practices are negatively affecting the environment leading to global warming and climate change. Therefore, this chapter systematically identifies four internal barriers including inadequate management commitment and support, insufficient technology competence and infrastructure, financial constraints, the uncertainty of economic benefits, and eight sub barriers within an organization concerning green concepts implementation. Moreover, this chapter also identifies four external barriers including lack of stakeholder's interest, inadequate environmental administrative support, scarce academic research, and lack of green collaborative practices, and eight sub barriers outside an organizational context concerning green concept implementation. The barriers in this research were identified by reviewing the existing literature on the topic. This chapter advances the green literature by identifying multiple barriers and challenges to the successful implementation of green concepts in organizations. This is of significance as if these barriers are tackled strategically, it would reduce environmental degradation problems and help make financial gains. Moreover, this research can help managers understand the key barriers to green concept implementation and provide guidance to them when attempting to implement green practices in their organizations. This research would also motivate researchers to extend further investigation on how to overcome such barriers and find out strategies to mitigate the barriers to green concept implementation to effectively address environmental issues.

Abstract
Purpose
The purpose of this paper is to investigate the impingement of lean manufacturing practices (LMPs) in small and medium enterprises (SMEs) of Northern India and their relationship with firm performance. This paper makes an attempt to identify the lean practices, which are more beneficial and their impact on firm performance.
Design/methodology/approach
In this study, a qualitative survey of 183 Northern India SMEs is collected and analysed using correlation, regression, canonical analysis and ANOVA test are conducted for developing relationships between them.
Findings
The outcome of this study indicates that the embracement of lean is necessary for their survival in this competitive spirit. Lean practices helped the SMEs to cope up with the persistent stress given by the spirited market. From the data investigation, it is revealed that total productive maintenance, supplier management, just-in-time and five S practices enhance the firm performance. Other practices such as plant management practices, operational and people practices found in a lesser extent than previous ones. From the correlation, it is revealed that lean practices have a strong relationship with firm performance. In one-way ANOVA test results indicating that the number of firms, which are less in the initial stage of lean implementation and much more impressive in a transition stage.
Research limitations/implications
The chosen approach for this research study was the cross-sectional one limited to the northern region of India and the investigated variables.
Practical implications
This study will help the stakeholders and manufacturers to enhance the performance of firms using LMPs, especially in a developing country. From these findings, practitioners and academicians would focus on vital issues related to firm enhancement apart from operational measures.
Originality/value
This study is one of the first attempts in which relation is developed between LMPs and firm performance and further data are investigated using canonical cross loadings and ANOVA analysis.

Abstract
Purpose
In response to strict regulations, high customer pressure, climate change and scarcity of natural resources, manufacturers have reassessed their operation and performance strategies to balance the sustainability and competitiveness needed to pursue a long-term competitive advantage toward an endurable business. The purpose of this paper is to fill the gap between lean and sustainability, analyzing the sustainable lean manufacturing (SLM) effect on performance in the Brazilian automotive sector.
Design/methodology/approach
This study divided the performance into Triple Bottom Line (TBL) drivers: Economic, Social and Environmental, and developed six hypotheses for assessing the multidimensional performance of SLM organizations. Empirical data was collected with 127 usable responses, and the models were tested using partial least squares structural equations modeling. The results of this study are valid and adequate models and revealed that environmental, operational and social performance are significantly improved through SLM adoption in Brazilian automotive studies. In addition, analyze the interaction among the TBL’s drivers.
Findings
The results revealed positive and direct improvements in economic, social and environmental performance enhanced LM adoption. In addition, the results obtained in this study reveal that social drivers are more sensitive to prejudice due to simultaneous other driver improvements overlapping the workforce.
Originality/value
These findings are beneficial for company leaders and researchers working to improve the organization’s performance in these drivers, especially within companies in developing countries. These results explored different aspects of performance evaluation supporting a holistic view of the organization toward sustainability performance. Also explored different regulations and incentives for automotive companies that comply with specific sustainable goals.

Abstract
Purpose
The increased awareness among consumers and strong competition have forced companies to put extra efforts and fulfill their social responsibility along with earning profits. The research aims to review corporate social responsibility (CSR)-related literature specifically determinants, outcomes and disclosure of CSR while adapting a comparative approach for developing and developed countries.
Design/methodology/approach
Based on theoretical frameworks of CSR, the authors have reviewed past studies conducted in past 10 years. While using keywords and synonyms, the databases such as JSTOR, Emerald, SpringerLink and ScienceDirect were used for searching impact factor and Scopus journals. Thematic analysis has been used as a method in the paper while identifying the key themes in study and presented them separately. Only those articles have been included which have key words in abstract. The review has been done while using logical process to improve inter-rater reliability. The key databased have been used to cover articles from multiple and diverse domains. The authors studied the key themes of literature found and identified the gaps. The paper has also incorporated the comments of authors who conducted credible studies.
Findings
It has been found that there are different determinants which lead the companies to involve in CSR practices in developing and developed countries. It has also been found that consumers are more aware about CSR in developed countries which effects the CSR decisions by firms. There is lack of literature available in developing states and researchers have been focused to conduct studies mainly developed countries such as in Europe and USA. Mostly the CSR behavior of companies has been linked with their financial and reputational benefits in empirical studies. There is large gap in literature on CSR involvement in small companies. The authors have developed and presented model which provides comparison of determinants leading toward CSR involvement by companies in developed and developing countries. Another framework has been developed which summarized all the factors which force the company to take part in CSR activities.
Practical implications
The study has made significant contribution toward research field and summarized the determinants based on social and economic factors of countries. The study also presented the comparison between CSR in developing and developed country which is valuable contribution by the authors. The study has also found lack of progress in theory development in this area which needs further attention by researchers. The authors have developed a model and framework which will contribute in field of CSR.
Originality/value
This is the review paper which provides integrated view of literature regarding determinants, outcomes and disclosure of CSR in developing countries while using a comparative approach.

Abstract
Purpose
Demanding and highly competitive business environment has stimulated small and medium enterprises (SMEs) to restructure their manufacturing practices. Lean manufacturing (LM), a comprehensive alternative, is now being adopted, notably by manufacturing organizations, to increase business effectiveness and performance through a variety of lean approaches. Lean implementation, however, ran into a number of difficulties, which showed that non-technical factors such as human-related practices must also be integrated if lean is to be successful. This study aims to examine a thorough overview of the various human-related lean practices (HRLP) mentioned in recent literature and to determine which of them is more pertinent to a successful LM implementation in SMEs.
Design/methodology/approach
A total of 193 publications published in 45 journals between 2013 and 2023 and based on the 4 reputable publishers, namely, Science Direct, Emerald Online, Taylor and Francis and Springer Link, were gathered based on a systematic literature review of peer-reviewed journal articles in LM.
Findings
The amount of research on human resource management and lean management that has been conducted has increased dramatically during the past few years. The outcome of this study will offer a thorough analysis of soft lean practices found in the LM literature that manufacturing SMEs should take into account while implementing lean.
Research limitations/implications
The scope of this research is restricted to a survey of scholarly works using the terms “Lean manufacturing” or “Lean production” as well as “human” or “people” or “soft-lean practices” in the title. Furthermore, only works published in scholarly publications that have undergone peer review were included. Also, due to the authors’ linguistic restrictions, only English articles were used. The HRLP linked to a smooth lean transition are described in this research. Thus, it can be used to assist the production and human resource departments in raising an organization’s long-term performance.
Originality/value
The study gives researchers a better grasp of the direction the subject is taking and what gaps still exist, which aids them in focusing their research on HRLP in small- and medium-sized businesses.

Abstract
Purpose
The view that dynamic capabilities theory can help explain how lean organizations improve has been put forward by scholars. However, there is still a lack of research on the matching relationship between the application of lean practice and the internal elements of enterprise organization from the perspective of dynamic capabilities. The purpose of this study is to validate the moderating effect of dynamic capabilities on the relationship between lean practices and operational performance.
Design/methodology/approach
This study used the method of survey and empirical research to collect sample data from 263 enterprises in China. Through literature review, this study put forward the moderating hypotheses around dynamic capabilities, lean practices and operation performance and used the method of regression analysis to validate these hypotheses.
Findings
The results showed that dynamic capabilities have a partially moderating effect on the application of lean practices. Specifically, dynamic capabilities have a significant moderating effect on the relationship between just-in-time, total quality management, total preventive maintenance and operational performance, while dynamic capabilities have no significant moderating effect on the relationship between human resource management and operational performance.
Originality/value
The research conclusion complements and enriches the lean practices literature from the perspective of dynamic capabilities. Existing studies mainly focus on the moderating role of external environmental factors, while there is a lack of empirical research on the role of dynamic capabilities in lean practices literature. The research results will help enterprises further understand the matching relationship between lean practices and dynamic capabilities and then improve the success of lean practices application.
