Abstract
The problem of portfolio optimization involves selecting appropriate stocks for investment by maximising the returns from the portfolio at a pre‐specified level of risk. The current approaches center around Markowitz’s mean variance optimization method that suffers from several pitfalls like instability of beta, and are either computation extensive or lead to sub‐optimal solutions. The present work suggests a heuristics and evolutionary approaches to portfolio optimization. The approach is computationally less intensive. It further extends the approach to include cardinality constraints that limit a portfolio to have a specified number of assets, and to impose limits on the proportion of the portfolio held in a given asset. The heuristics technique is employed for asset selection while the evolutionary technique is used for allocation of funds among the already selected assets. The approach is capable of handling a large number of instruments and scenarios, and is relatively stable to minor variations of the inputs, as is practiced in real life situations. The performance from this approach compares well with the Markowitz’s model, and performs better than the stock market indices of US and India.

Abstract
Purpose
This study aims to conduct a bibliometric analysis to provide a comprehensive picture and identify future research directions to enrich the existing literature on behavioral biases.
Design/methodology/approach
The data set comprises 518 articles from the Web of Science database. Performance analysis is used to highlight the significant contributors (authors, institutions, countries and journals) and contributions (highly influential articles) in the field of behavioral biases. In addition, network analysis is used to delve into the conceptual and social structure of the research domain.
Findings
The current review has identified four major themes: “Influence of behavioral biases on investment decisions,” “Determinants of home bias,” “Impact of biases on stock market variables” and “Investors’ decision-making under uncertainty.” These themes reveal that a majority of studies have focused on equity markets, and research on other asset classes remains underexplored.
Research limitations/implications
This study extracted data from a single database (Web of Science) to ensure standardization of results. Consequently, future research could broaden the scope of the bibliometric review by incorporating multiple databases.
Originality/value
The novelty of this research is to provide valuable guidance by evaluating the existing literature and advancing the knowledge base on the conceptual and social structure of behavioral biases.

Abstract
Purpose
The purpose of this study is to explore the relationship between transformational leadership and knowledge sharing behavior in freelancers. Also, the study focuses upon mediation of the relationship by employee engagement and moderation by social support.
Design/methodology/approach
Confirmatory factor analysis was used to find validity and reliability of the model under study. To study the relation between variables, the Pearson correlation was used. Further, the PROCESS macro of Hayes (2013) was used to test mediation and moderated mediation.
Findings
Transformational leadership influenced knowledge collecting and knowledge donating behavior in freelancers. The relation was mediated by employee engagement. Social support was found to moderate the mediated path by employee engagement between transformational leadership and knowledge collecting behavior. A similar result was found for knowledge donating behavior as a dependent variable.
Research limitations/implications
The model under study can be tested in other contexts with extended data.
Practical implications
The study asserts importance on freelancers in knowledge sharing in client organizations; leaders should take a transformational role to create a culture of free flow of knowledge and information between various types of employees.

Abstract
Purpose
This paper aims to explore the determinants of intention towards the use of agro-advisory mobile applications by extending the technology acceptance model (TAM) with addition of the following constructs: result demonstrability (RD), trust, self-efficacy (SE) and mobile usage proficiency (MUP).
Design/methodology/approach
The study employed a survey on farmers (n = 446), which was analysed through structural equation modelling using Analysis of Moment Structures (AMOS).
Findings
The results show that RD and farmer's trust on agro-advisory mobile apps (AAMA) positively impact their perceptions of usefulness. Also, farmer's SE and MUP positively affect their perceptions of ease of using AAMA. Further, interestingly, farmer's attitude towards the AAMA fully mediates the relationship between perceived usefulness and perceived ease of use on intention to use them.
Research limitations/implications
Understanding the antecedents of agro-advisory mobile application offers a unique contribution to policymakers, private firms, and non-government organizations by proving key insights on the acceptance of agriculture based mobile technologies in context of developing nations.
Originality/value
To the best of author's knowledge, this is one of the first research enquiries on the adoption of agro-advisory mobile applications. The new theoretical framework adds to the original TAM and offers novel insights that are helpful in augmenting the current understanding on AAMA and their acceptance by the beneficiaries.

Abstract
Purpose
From last few decades, logistics management (LM) constitutes a global concern among organization’s supply chain (SC) to improve their business effectiveness. The purpose of this paper is to uncover and analyze the critical factors (CFs) related to the implementation of effective LM concept and benchmark the SC performance.
Design/methodology/approach
The most common (16) CFs were identified and selected through literature and use of the Delphi method. Subsequently, the selected most common CFs were analyzed to distinguish their causal relations using the fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) technique under unclear surroundings. A case example of Indian Logistics Company is also discussed to reveal the practical applicability of the research.
Findings
Provision of the effective information communication and technological developments in the system and Management dedication, support and involvement CFs are found to have the top most influences in the effective implementation of LM. This paper also groups the CFs into cause and effect relationship which provides valuable insights for analyzing the factors in successful implementation of LM.
Practical implications
This work attempts to understand the different CFs, their relative position and the importance rating in the system, due to which, managers can differentiate the factor which greatly affects the concepts of implementing LM, and thus, improvements can be made accordingly.
Originality/value
First, this work offers 16 CFs to LM implementation from a SC scenario. Second, in the context of contributing to the theory, the combined Delphi and fuzzy DEMATEL-based model is provided that helps in managing the logistic related issues effectively.

Abstract
Purpose
This study aims to provide an overview of the development of corporate governance and ownership structure literature and offers a synopsis of the top contributors, influential articles, journals and potential research prospects on this subject.
Design/methodology/approach
This study used bibliometric analysis to review the literature. In all, 1,368 articles published between 1992 and 2022 in Scopus-indexed journals were considered.
Findings
This review reveals the top leading authors, institutions, countries and sources in the ownership structure research. Using bibliographic coupling, this study fetches four significant clusters. The theme of the first cluster revolved around cash holding. The second and third groups revealed how distinct characteristics of ownership impact the performance of the firm and disclosure decisions, respectively. The last and fourth cluster deals with risk-taking activities in financial institutions. Furthermore, this study suggests a road map in each cluster for future research.
Originality/value
Ownership structure plays a significant role in corporate governance by affecting manager incentives and determining the extent of monitoring. Previous studies have contributed to this field while focusing on the board of directors. However, no study synthesises the literature on ownership structure within corporate governance, which is the core element of the corporate governance system. Hence, this study gives a comprehensive overview and determines the latest and prominent research in ownership structure within corporate governance through bibliometric analysis.

Disrupted FSC escalated the societal concerns related to food safety and security. The purpose of this study is to consolidate various issues, exploring the perspectives associated with the agricultural practices, food industries and society concerns related with the FSC performance system dynamics amid of COVID-19 pandemic.
Design/methodology/approach
To structure this work, a detailed research literature insight focussing on the key findings associated with the past disease outbreaks like influenza, avian flu, Ebola, bird flu, SARS, foot and mouth disease and ongoing phase of COVID-19, encompassing the perspective related with various agricultural and concerned supply chain practices is clustered. Furthermore, issues having relevancy with the notion of this work, sourced from platforms of print and electronic media have been incorporated to ground the reality associated with the impacts, for better visualisation of the perspectives.
Findings
This study outlays the key findings which are relevant with the past pandemic outbreaks from the core of the research literature. It details the impact of the current COVID-19 scenario on the various FSC operations, focussing on dimensions allied with the industry, economic and society concerns. For the same, to mitigate the effects, relief measures focussing on the short- and long-term perspectives have been incorporated. Steps ramped up by the Government of India (GOI) to safeguard masses from the threat of food security, accelerate pace of the FSC operations and upscale operating capacities of the industries and agriculture practices have incorporated.
Research limitations/implications
Presented work is persuaded amid of the COVID-19 lockdown restrictions hence it outlays the theoretical perspectives only. But, these perspectives portray the ongoing scenario's impacts, extending its implication to the people coming from the industry and academia background. This study can felicitate the government bodies to make them familiar with the various impacts which indented the FSCs, food industries and added woes to the society concerns.
Originality/value
India is the second largest populated nation of the world, and outspread of the COVID-19 has capsized the FSCs and raised the various instances, making population vulnerable to the threats of food insecurity. This study encompasses effect of the FSC disruption by incorporating its effect on the food industries practices, societal issues and extending possible relief measures to restructure the FSC dynamics. As of now, study focussing on the Indian FSC concerns, detailing of impacts due to pandemic outbreak, relief measures to sail out of the hard times are not available.

Abstract
Purpose
Businesses nowadays face unprecedented pressures from stakeholder groups to become more transparent by issuing comprehensive reports describing their environmental, social and governance (ESG)-related activities, strategies and policies. This paper’s primary motivation is to understand which ESG disclosure factors are relevant for large Czech companies.
Design/methodology/approach
To achieve the above-stated goal, the total ESG disclosure index, consisting of three subindexes (ESG) was constructed and calculated for the 100 largest Czech companies. Furthermore, the relationships between firm-level factors and ESG disclosure indexes were estimated by using censored regression models.
Findings
This study found that revenue, number of employees and profitability positively influenced the total ESG disclosures. On the level of the three ESG components, this study found that revenue positively impacted environmental and governance disclosures while the number of employees positively affected social and governance disclosures. Moreover, profitability affected social and governance disclosures positively for large Czech companies. However, this study did not observe a significant relationship between board attributes and ESG disclosures.
Originality/value
This paper extends academic literature on ESG disclosures by verifying the significance of firm-level factors in the context of Czech business realities before the adoption and transposition of the Corporate Sustainability Reporting Directive. More specifically, this study has investigated the ESG reporting together and separately for ESG factors. This separation is vital as firms vary in reporting processes across these factors.
