Abstract
This paper aims to focus on technical and economical analysis of small scale wind/solar hybrid system for domestic consumers. The analysis is carried out on HOMER II simulation software. Pakistan is one of those developing countries which are encountered with severe energy crises. The purpose of this paper is to introduce a technically and economically feasible system to meet the domestic consumer’s demand, as well as contribute to the central grid. HOMER Energy software is used to analyze different systems and to obtain the most reliable and feasible system for the customer. Simulation was carried out to find an economically and technically feasible system. Sensitivity analysis was carried out with hub height, PV De-rating factor, PV life, Wind turbine life. Change in hub height drastically affected energy production and economic prospect as the main factors of the system. Implementing such type of small hybrid systems on domestic level can be truly helpful to overcome energy shortage.

Abstract
Purpose
In current vista of corporate governance (CG), whistleblowing (WB) has become critical for practitioners, researchers and other stakeholders. This study aims to identify, prioritize and analyze the interrelationships of determinants of effective WB on the basis of opinion of a medium-sized panel of experts.
Design/methodology/approach
It is a cross-sectional descriptive study conducted in the field setting. A self-administered structured questionnaire was used to collect primary data from the respondents. This study follows an interpretive structural modeling (ISM) approach.
Findings
This study found that the factor “specific law for WB” has maximum driving power but minimum dependence and occupies bottom level (the most critical level) in the ISM model. The Matrice d’Impacts Croisés Multiplication Appliquée á un Classement analysis revealed that there is no autonomous and dependent factor in the model. There are eight linking factors and only one independent factor.
Research limitations/implications
The study found that the factor “specific law for WB” has maximum driving power but minimum dependence and occupies bottom level (the most critical level) in the ISM model. The Matrice d'Impacts Croisés Multiplication Appliquée á un Classement analysis revealed that there is no autonomous and no clear-cut dependent factor in the model. There are eight linking factors out of which five have high dependence as well, and there is only one independent factor.
Practical implications
This study has ensued in identification of significant challenging issues in WB and in development of interrelationships to gain insights into priority of these issues. This study uses limited primary data in context of Pakistan; therefore, generalizability of the findings is limited.
Originality/value
This study presents a novel theoretical and conceptual model focused on effective WB. The value of the study on effective WB is highly relevant for today’s complex organizations but incipient in literature. The insights provided by the study have vital importance for corporations to embark on the regime of reforms in CG.

Abstract
Purpose
Green knowledge management (GKM) has become a critical factor for modern organizations, offering a multifaceted approach to enhancing business operations while promoting environmental sustainability. The purpose of this paper is to review the literature and explore how GKM helps companies reduce their ecological footprint by digitalizing processes and minimizing physical storage needs, thus aligning with growing expectations for corporate environmental responsibility. The necessity for conducting a GKM review is underscored by the increasing recognition of sustainability, environmental performance and as a critical component of organizational corporate success in the contemporary business landscape.
Design/methodology/approach
This study conducted a bibliometric analysis of 994 papers related to GKM from 2005 until August 2024.
Findings
Over the 20 years of research on GKM, this bibliometric analysis drew the interlinked relationships between main theme of KM in the context of sustainable practices, processes, social and related theories. This study identifies green innovation, digital transformation, green and lean supply chains, leadership and technology tools. Future research can explore themes such as green and lean processes, barriers and enablers, role of leadership and ambidexterity in green supply chain integration using different theoretical lenses.
Research limitations/implications
Although the findings of this study are important to GKM research, there are a number of limitations to this investigation. The research database used exclusively was the Web of Science and Scopus, which contained the indexed papers. Future investigations may draw from various databases, such as EBSCO and Google Scholar. Additionally, the use of topic modelling and other artificial intelligence frameworks could enhance research analysis. Subsequently, research papers may expand their scope to encompass conference papers, books and book chapters, in addition to articles.
Practical implications
This review gives a holistic understanding of GKM practices across various sectors which not only enhances organizational performance but also contributes to broader environmental goals. This study offers an understanding on GKM on holistic approach that combines total quality management (TQM), absorptive capacity and collaborative frameworks to foster innovation and sustainability.
Originality/value
It is evident from the review that research in GKM is evolving gaining momentum. This review provides a comprehensive understanding of the GKM literature, from its earliest forms of basic concepts aligned with the sustainability and progressing more into the concepts of GKM adoption for green innovation by highlighting multiple theories, factors and gaps in the studies.

Abstract
Purpose
A perusal of extant literature suggests asymmetric devotions in empirical research that overlooks unique social and industrial dynamics of married working women in highly competitive male-dominated industries. Drawing on the social role theory, the study addressed this asymmetry by proposing a multivariate regression model that examined performance drivers of married female real estate brokers, as mediated by organizational, cognitive and social influences.
Design/methodology/approach
The study employed a descriptive design. A structured electronic questionnaire was used to collect data from a sample of 256 married female brokers who are active on online messaging platforms. Snowball sampling was used to reach the research participants. Collected data were subjected to multivariate regression analysis.
Findings
The results infer that social influences were the most significant drivers of married female brokers in the real estate industry (r = 0.932, p < 0.05, F = 556.581). Significant interventions of diversity management, work-life balance, family support and access to economic opportunities were found.
Practical implications
In acknowledging the societal stereotype and culturally imposed burdens married women face in emerging economies, the study advanced theoretical, practical and policy initiatives for a more inclusive, supportive and learning-oriented work environment.
Originality/value
The novelty of the paper lies in its exposition of the unregulated real estate brokerage market in an emerging economy and the dynamic organizational, cognitive and societal influences of married female brokers.

Abstract
Purpose
This research focuses on analyzing the impact of digital transformation (DT) on the green innovation performance of Spanish wineries, as well as the mediating effect of green knowledge sharing (GKS) on this main relationship, as well as the moderating role of top management environmental awareness (TMEA) on the GKS-green innovation performance linkage. In addition, age, size and protected designation of origin (PDO) membership are used to increase the precision of the cause–effect relationships examined.
Design/methodology/approach
The study proposes a conceptual model based on previous studies, which is tested using partial least squares structural equation modeling, with data collected from 196 Spanish wineries between September 2022 and January 2023.
Findings
The results of the research reveal the existence of a positive and significant relationship between the development of DT and green innovation performance of Spanish wineries, as well as the partial mediation of GKS in this link and a positive moderation of TMEA in the GKS-green innovation performance bond.
Practical implications
Winery executives should prioritize aligning DT with TMEA to drive green innovation performance. Additionally, it is recommended that they actively promote GKS within their wineries to enhance sustainability performance and strengthen their competitive positioning in an eco-conscious market.
Originality/value
The originality of the study derives from its pioneering character, as the research enters unexplored terrain by investigating the role of the GKS as a mediator in the relationship between DT and green innovation performance, as no previous research has ventured in this direction.

Abstract
Purpose
This study aims to inspect the impact of Chief Executive Officers’ (CEOs) education in a “specific field,” such as CEOs with science and engineering backgrounds on firms’ innovation. Based on agency theory, this study also reports how an endogenous factor, i.e. CEOs’ compensation, and an exogenous factor such as intellectual property rights (IPR), moderate the CEOs with a scientific background (CEOSB)-innovation relationship.
Design/methodology/approach
This study uses a sample of Chinese nonfinancial firms listed on the Shanghai and Shenzhen Stock Exchanges from 2008 to 2018 by applying the ordinary least squares regression method. To deal with the endogeneity issues, this study also performs a series of additional tests.
Findings
The results indicate that the effects of CEOSB on the firm innovation activities are positive and significant. Further, this study finds that CEOs’ compensation and IPR protection positively and significantly moderate the CEOSB-innovation relationship. These outcomes are robust to a series of additional tests.
Research limitations/implications
The results of this study have valuable implications for various stakeholders interested in stimulating innovation. To sum up, the results of this study inculcate these stakeholders that the enhancement of firm innovation is contingent on the appropriate selection of CEOs, effective compensation packages and IPR regulations.
Originality/value
Distinct from the existent studies, the focus of the study is on the perspectives of CEOs’ scientific backgrounds. Further, based on agency theory, this study also reports how CEOs’ compensation and IPR protection moderate the CEOSB-innovation relationship, which has not been tested earlier to our knowledge, especially in the context of an emerging economy like China.

Abstract
Purpose
The aim of this study is to measure the impact of the factors affecting construction labor productivity by focusing on different types of construction works during and after the COVID-19 pandemic in Turkey, as well as discuss solutions and immediate actions.
Design/methodology/approach
This research was conducted in two steps. First, a quantitative survey was carried out to determine the dimension of factors negatively affecting construction labor productivity and the loss rate of different construction works from the employee perspective. The factors were identified through a literature review. The crucial relationships were highlighted as a result of a statistical analysis. Second, a survey was performed to determine the loss rate through a comparison of man-hour values before and after the beginning of the pandemic from the employer perspective. After an analysis and comparison of the results, semi-structured interviews were performed to discuss all findings and discover ways to mitigate the impacts of COVID-19 on construction labor productivity.
Findings
The results of the study clearly show that construction labor productivity was deeply affected by the coronavirus disease (COVID-19) pandemic. Legal obligations, such as social distancing, wearing masks, and limitations on the number of workers, have been major drivers for lower labor productivity. Such obligations have a profound impact on interior construction works, especially based on teamwork. Concerning employer and labor-related factors, problems with getting payments on time, loss of income, and financial hardships are the leading factors resulting in decreased worker performance. Excavation, insulation, and plastering works were determined as the most affected construction works under the influence of the COVID-19 pandemic.
Research limitations/implications
The quantitative portion of this study is limited to a sample of respondents in the Turkish construction industry. Further research is necessary to provide an in-depth review into construction labor productivity in other countries with a larger respondent sample. Another limitation is sourced by the dynamics of the COVID-19 pandemic, which may turn out that some findings are outdated. Despite these limitations, the insights from this study may enable employers to understand the major drivers and deep impacts of labor productivity loss by uncovering the main vulnerabilities during the pandemic. Recommended measures may also help policy-makers and stakeholders in the construction industry take necessary and immediate actions to ensure better construction labor productivity.
Originality/value
The study may contribute to a better understanding of a pandemic's impact on labor productivity by focusing on both employee and employer perspectives, especially in developing countries. The paper may help employers decide which priority measures are required for each construction work separately. The study is crucial not only for minimizing the negative effects of the COVID-19 outbreak on labor productivity but also for preparing for the post-pandemic era.

Abstract
Purpose
The purpose of this study is to investigate the factors that influence customers’ green consumption intention by integrating social cognitive theory (SCT) and the cognitive affective conative (CAC) framework.
Design/methodology/approach
Survey questionnaire was employed to collect data. Then, this study adopts artificial neural network (ANN) to check the robustness of partial least squares-structural equation modelling (PLS-SEM) empirical results.
Findings
The findings confirm that social media marketing and collectivism are potent external stimuli to promote green consumption intention. Significant variables identified in the PLS-SEM analysis were used for ANN models, demonstrating the robustness of the PLS-SEM findings.
Originality/value
The primary theoretical contribution lies in the application of SCT theory and the CAC framework in the context of green consumption, an area that has been relatively underexplored in previous studies. Additionally, the study provides managerial implications for marketers by emphasising the significance of social media marketing and collectivism in influencing consumers’ cognition and affect.

Abstract
Purpose
The purpose of this paper is to present a systematic literature review to identify new avenues of research in line with the ongoing changes in quality and management required to firms, especially regarding customers.
Design/methodology/approach
This study uses a systematic review of the literature contained in the three databases Ebsco, JSTOR, and Springerlink and on the search engine Google Scholar.
Findings
An analysis of the literature identifies three different clusters of papers: “identification” papers, which show that customer focus has gained importance in recent times; “implementation” papers, which highlight that a general or shared model or scale to successfully implement total quality management (TQM) does not yet exist; and “impact-on-performance” papers, which show that few studies have considered the relationship between TQM and the issues of both marketing and performance, underlining the most significant gap in the TQM literature.
Research limitations/implications
This study is limited by the small number of databases and search engines used and by the restricted number of keywords used in searching these sources.
Practical implications
This work highlights a gap in the existing research and thus an incomplete consideration of the interplay between management, marketing, and quality issues, all centered on customers and other stakeholders. Researchers and firms are thus advised to adopt a wider view that considers the role of the quality process to support the firm’s engagement of customers in activities that enhance both the customer role and customer satisfaction.
Originality/value
This study uses a systematic literature review to review all critical factors of TQM and identifies new research avenues and different approaches to implementing TQM, focusing on the central role that customers play in achieving firm success.

Abstract
Purpose
Misinformation on social media has become a great threat across the globe. Therefore, the authors aim to provide a comprehensive understanding of social media users' misinformation combating behavior, especially during the COVID-19 pandemic. Specifically, the authors merged the uses and gratifications theory, social cognitive theory and theory of prosocial behavior into one theoretical framework (e.g. information seeking, status seeking, entertainment and norms of reciprocity) to understand their effect on users' prosocial media sharing experience and misinformation self-efficacy to combat misinformation.
Design/methodology/approach
The authors collected data from 356 social media users through “Google Forms” during the third wave of coronavirus in Pakistan. Further, the authors applied structural equation modeling for hypotheses testing.
Findings
The authors noted that entertainment and perceived norms of reciprocity positively affect social media users' prior experience and misinformation self-efficacy to enhance their misinformation combating intention. However, information seeking positively affects social media users' prior experience and insignificantly affects their misinformation self-efficacy. Similarly, status seeking was noted to be insignificantly associated with social media users' prior experience and misinformation self-efficacy.
Research limitations/implications
The authors tested this model of misinformation combating intention in a developing country during the COVID-19 pandemic and noted that entertainment and status seeking motives are context-specific. Therefore, this study may likely benefit researchers, academicians and policymakers to understand the causal relationship between motivations and the behavior of combating misinformation on social media within a developing country.
Originality/value
In this study the authors merged three theories (e.g. uses and gratifications theory, social cognitive theory and theory of prosocial behavior) to understand information seeking, status seeking, entertainment and norms of reciprocity as the main motives for social media users' misinformation combating intention.
