Abstract
Purpose
The purpose of this paper is to propose the dynamically balanced mechanism for cleaning unit used in the agricultural thresher machine using the system of point masses.
Design/methodology/approach
The cleaning unit works on crank-rocker Grashof mechanism. To balance the mechanism, the shaking forces and shaking moments are minimized by optimizing the mass distribution of links using the dynamically equivalent system of point masses. The point mass parameters are taken as the design variables. Then, the optimization problem is solved using Jaya algorithm and genetic algorithm (GA) under suitable design constraints.
Findings
The mass, center of mass and inertias of each link are calculated using optimum design variables. These optimum parameters improve the dynamic performance of the cleaning unit.
Originality/value
The proposed methodology is tested through the standard four-bar mechanism taken from literature and also applied to the existing cleaning mechanism of the thresher machine. It is observed that the Jaya algorithm is computationally more efficient than the GA. The dynamic analysis of the proposed mechanism is simulated using ADAMS software.

Abstract
Purpose
This paper aims to propose a dynamically balanced mechanism for cleaning unit used in agricultural thresher machine using a dynamically equivalent system of point masses.
Design/methodology/approach
The cleaning unit works on crank-rocker Grashof mechanism. This mechanism can be balanced by optimizing the inertial properties of each link. These properties are defined by the dynamic equivalent system of point masses. Parameters of these point masses define the shaking forces and moments. Hence, the multi-objective optimization problem with minimization of shaking forces and shaking moments is formulated by considering the point mass parameters as the design variables. The formulated optimization problem is solved using a posteriori approach-based algorithm i.e. the non-dominated sorting Jaya algorithm (NSJAYA) and a priori approach-based algorithms i.e. Jaya algorithm and genetic algorithm (GA) under suitable design constraints.
Findings
The mass, center of mass and inertias of each link are calculated using optimum design variables. These optimum parameters improve the dynamic performance of the cleaning unit. The optimal Pareto set for the balancing problem is measured and outlined in this paper. The designer can choose any solution from the set and balance any real planar mechanism.
Originality/value
The efficiency of the proposed approach is tested through the existing cleaning mechanism of the thresher machine. It is found that the NSJAYA is computationally more efficient than the GA and Jaya algorithm. ADAMS software is used for the simulation of the mechanism.

Abstract
Purpose
This paper aims to present the optimum two-plane discrete balancing procedure for rigid rotor. The discrete two-plane balancing in which rotor is balanced to minimize the residual effects or the reactions on the bearing supports using discrete parameters such as masses and their angular positions on two balancing planes.
Design/methodology/approach
Therefore as a multi-objective optimization problem is formulated by considering reaction forces on the bearing supports as a multi objective functions and discrete parameters on each balancing plane as design variables. These multi-objective functions are converted into a single-objective function using appropriate weighting factors. Further, this optimization problem is solved using discrete optimization algorithm, based on Jaya algorithm.
Findings
The performance of the discrete Jaya algorithm is compared to genetic algorithm (GA) algorithm. It is found that Jaya algorithm is computationally more efficient than GA algorithm. A number of masses per plane are used to balance the rotor. A comparison of reaction forces using number of masses per plane is investigated.
Originality/value
The effectiveness of the proposed methodology is tested by the balancing problem of rotor available in the literature. The influence of a number of balance masses on bearing forces and objective function are discussed. ADAMS software is used for validation of a developed balancing approach.

Abstract
Purpose
The present research investigates the role of product availability, environmental concern, and social media concerning the intention to purchase green food products by utilising the extended theory of planned behaviour framework in a developing economy.
Design/methodology/approach
A self-administered questionnaire collected information from 412 adults and educated consumers from Vadodara city in India. The questionnaire items were used to collect data from previous studies and further validated using confirmatory factor analysis. The data were further analysed using partial least square-structural equation modelling.
Findings
The study findings indicated that attitude and perceived behavioural control impact the purchase intention regarding green food products, while subjective norms were found not supportive. At the same time, product availability influences perceived behavioural control and increases the volitional control amongst consumers. Moreover, social media positively impacts the theory of planned behaviour’s key constructs.
Research limitations/implications
The outcomes of the present study provide marketing managers with enhanced insight into the relationship between consumers' perception and green food product consumption in the context of social media influence. The findings could help green food producers evaluate the extent of consumers' intentions to buy their products in developing countries.
Originality/value
To the best of the researchers’ knowledge, the present research is amongst the pioneers in India that focuses on the variables of the theory of planned behaviour, which led to knowing the role of green food availability and social media influence in green food products. At the same time, the focus on purchase intention concerning green food products adds to the study’s uniqueness.

Abstract
Purpose
Contemporary arguments around efficient public management (PM) envisage a limited role of the state for efficiency, effectiveness and austerity. On the contrary, the PM of the Covid-19 pandemic shows the significant role and depth of administrative state in multi-faceted ways. In this context, the purpose of this article is to examine the administrative role of the Indian state and the extent of its “stateness” in the PM of the novel coronavirus pandemic.
Design/methodology/approach
This article is a bifocal study of both the national and a single sub-national case. Following mixed qualitative methods, this article draws on government documents, interviews and recent media reports to examine the reemergence of a strong administrative state in India in the context of PM of the pandemic. This methodology allows us to go deep into the cases and provide a robust understanding of the underlying processes within the state that throw open some compelling insights on the PM of the pandemic.
Findings
This article shows the reemergence of a strong administrative state in multiple ways. It demonstrates that state’s administrative capacity is an outcome of both ideas within the state and its rationality that shapes policy strategies and planning. Further, a combination of learning, puzzling and powering plays a critical role in pandemic management. Exploring pandemic-induced state capacity in India sheds light on the administrative state’s emergence, extent and function in an emerging developing country setting.
Research limitations/implications
One of the major challenges of this study is the evolving nature of the pandemic. In this light, the study limits its focus to the earliest stage of the pandemic. Revisiting this paper in future would provide a more comprehensive picture. Furthermore, the study is limited to the national and a single sub-national case. This research will gain from including more sub-national and cross-country comparisons to test some of the conjectures presented in this paper.
Practical implications
This article shows that the state as a conceptual variable needs to be taken seriously to understand and explain the PM strategy, especially in times of crisis. It also persuades us to better understand the political power of “ideas” within the state to explain policy outcomes and evolving PM strategies.
Originality/value
This article seeks to push the frontiers of research on state capacity and PM by exploring how social learning and puzzling come together to consolidate policy paradigms. Through the lens of PM of the current Covid-19 pandemic by the Indian state, this article reflects on the reemergence of the administrative state. It examines the long-term ramifications of such a revival for both practice and theory of state capacity and PM in a large, diverse democracy, such as India.

Abstract
Purpose
Entrepreneurial intention is crucial in both entrepreneurship literature and practice. However, limited information exists regarding entrepreneurs’ intentions in the realm of social enterprise creation. This study aims to determine the social entrepreneurial intentions of Generation Z students within the Indian environment by utilising the theory of planned behaviour (TPB) and its applicability using personality factors like risk-taking ability, proactivity, empathy and emotional intelligence.
Design/methodology/approach
A survey method was used, and data was collected by Generation Z individuals at three public universities in India using a self-administered questionnaire. The study used a purposive sampling technique, and further, the model was tested using the partial least square-structural equation modelling technique.
Findings
The study findings supported the proposed model of extended TPB, demonstrating that factors such as emotional intelligence, risk-taking ability and proactiveness are found prominent in Indian students. Furthermore, the role of gender as a control variable reflected no effect on social entrepreneurial intentions.
Originality/value
This research enhances the literature on social entrepreneurship by offering novel insights into social entrepreneurial intention. It is among the pioneers of its type to examine social entrepreneurial intent concerning personality factors among students of higher education institutions. This study provides interesting insights for universities and policymakers since they play a crucial role in promoting these antecedents through education and stimulation by enhancing entrepreneurial culture in developing countries.

Abstract
Purpose
The purpose of this paper is to examine the effects of trade liberalization on gender earning differentials and female labour force participation by considering the interaction between changes in relative wages, intra-household bargaining power and social norms.
Design/methodology/approach
A three-sector general equilibrium model is developed where female labour supply is determined as a collective household decision and depends on male and female wages and intra-household power distribution. On the other hand, the effect of power distribution on female labour supply depends on social norms.
Findings
Comparative static analysis shows that a tariff cut may reduce female labour force participation and widen gender earning inequality if (i) the agricultural sector is more male labour-intensive than the informal sector, and the marginal utility of the woman from household work is higher than that of the man or (ii) the agricultural sector is more female labour-intensive than the informal sector, and the marginal utility of the woman’s household work is higher to the man than the woman. Policies to raise the empowerment of women might lead to favourable labour market outcomes for women if the marginal utility of the woman’s household work is higher to the man than the woman irrespective of the factor intensity condition.
Research limitations/implications
The results signify that the effect of trade liberalization hinges on both factor intensity conditions and the relative work preferences of women vis-à-vis men, which in turn is shaped by social norms.
Originality/value
The paper contributes to the scant theoretical literature on labour market consequences of trade liberalization by considering the gender equality implications of trade liberalization from a supply side perspective. The results of the model are used to explain the recent gendered labour market consequences in India in the aftermath of trade liberalization.

Abstract
Purpose
The purpose of this paper is to shed light on the paradoxical and dynamic nature of gender and leadership in India through a critical review of Indian film Mardaani.
Design/methodology/approach
The paper offers a critical review of an Indian film and relates the analysis to the context of gender and leadership in India.
Findings
The review shows that masculine stereotypes of leadership are simultaneously reinforced and shattered in the Indian context, and that despite all the odds, women’s role in organisations is characterised by dynamism and change. The paper situates this review in the broader context of gender, employment and leadership in India and offers a critical analysis.
Research limitations/implications
The analysis has two implications. First, it indicates that women are equally capable of demonstrating worthy leadership. Second, it highlights that being a leader, or “mannish”, in the workplace does not mean that women are not responsible for the domestic and caring duties at home. In fact, female leaders in India continue to do the double shift by struggling to balance their roles in the workplace and their personal lives.
Originality/value
The paper offers an original analysis of a Bollywood film in the context of gender, culture and leadership.

This research investigates the bond between stock market development and agricultural growth in African emerging economies from 1990 to 2020.
Abstract
Purpose
This research investigates the bond between stock market development and agricultural growth in African emerging economies from 1990 to 2020.
Design/methodology/approach
Agricultural value added to the gross domestic product measures agricultural growth and market capitalization and stock value traded measure stock market development.
Findings
The findings disclose that market capitalization negatively affects agricultural growth while stock value traded positively affects agricultural growth in the fully modified and dynamic ordinary least square techniques. The findings unveil bidirectional causality between labour and agricultural value added with unidirectional causality flow from agricultural value added to market capitalization and stock value traded.
Research limitations/implications
The governments should promote agricultural growth initiatives which stimulate stock market development. Effective methods required to encourage credit flow to the agricultural enterprises through the stock markets' intermediation should be promoted using aggressive policies which eliminate credit flow bottlenecks. Policy makers and regulatory authorities should implement policies which attract investors to the agricultural sector and encourage companies' listing in the stock markets. The capital market funding should be expanded to boost economic growth through agricultural value added.
Originality/value
Literature reveals divergent results on the relationship between stock market development and agricultural growth. Earlier studies provide conflicting findings on the bond between stock market development and agricultural growth. Some findings indicate positive link between stock market development and agricultural growth, while others show a negative association. Studies' results reveal opposing directions of causality between stock market development and agricultural growth.
