The purpose of this paper is to argue for theoretical integration as a major step in consolidation of the vast leadership literature. It is an attempt to lay out a basic canvas that could be further used for building an integrated theory of leadership.

The concept matrix framework (Webster and Watson, 2002) has been used for analytical abstraction to organize the published research on leadership and distill certain commonalities. The paper finally proposes certain pivots for theoretical integration of the leadership literature.

A thorough analysis of the leadership literature and the identification of commonalities within the various theories help the authors to identify the change and collective filter, outcomes of leadership, organizational outcomes, leadership role, sources of leadership, processes within the larger leadership process and the context as the pivots for building an integrated theory of leadership.

While the paper is not a detailed literature review and lacks predictive power, it is a synthesis of the published literature. The paper proposes a descriptive model meant to provide a sound foundation for an integrated theory of leadership.

The paper provides a framework to reduce the complexity and ambiguity of leadership research literature and could be utilized as a starting platform for an integrated theory of leadership. It is hoped that this shall also provide leaders and leadership training providers with a more holistic approach for leadership assessment and development.

Based on a survey of literature, the explanation of the leadership process, suggestions for evaluation of quality of leadership and pivots for theoretical integration are the main contributions.

This study aims to investigate the mediating effect of concern for information privacy between e-HRM and job stress that eventually develops a turnover intention among employees.

A survey questionnaire was used on working professionals employed in the service and manufacturing sectors. A total of 178 usable responses were collected adopting a convenient snowball sampling technique. PLS-SEM was used to analyze and investigate the hypothesized relationships.

The study found that higher perceptions of e-HRM strength led to less concern for information privacy breaches. Further, concern for information privacy was positively associated with employee job stress and turnover intention. A positive relationship between job stress and turnover intention among employees was also established. Moreover, perceived concern for information privacy fully mediated the relationship between e-HRM and job stress and, eventually, turnover intention among employees.

Organizations should focus on ensuring considerable e-HRM strength while adopting and implementing e-HRM practices; failing may lead to concerns for employee privacy, job stress and eventually turnover intention among employees.

To the best of the authors’ knowledge, the study is among the first few studies to identify perceived concern for information privacy as a consequence of e-HRM reflecting the dark side of e-HRM.

The purpose of this paper is to extend the job demands-resources (JD-R) model by including the factor of “personal demands” and conceptualise experience on personal and job dimensions separately as personal thrust and job thrust. Further, different psychological work states that individuals experience through intra-dimensional balance across personal and job dimensions are proposed.

The paper explains various possible psychological work states experienced by a job incumbent by conceptually developing intra-dimensional fluctuations within the person and job dimensions, respectively, as the new concepts of person and job thrust.

Personal thrust and job thrust have been identified as the two dimensions which impact the work state. Complete engagement and complete disengagement have been identified as two ends of a continuum. Complete work engagement is defined as the balance across these two dimensions. Various combinations of balances and imbalances across these two dimensions results in four different states of disengagement identified as work exhaustion, work boredom, work search and work neutrality.

This paper suggests a novel approach to using personal demand to look at work states which would significantly impact existing research in the JD-R model. This paper tries to bridge the gap between work engagement as a construct and the psychological work states as a phenomenon. Further, it is contended that the psychological work states are manifestations of the interactions between the two dimensions identified as personal and job thrust, which could further be developed into various work-related attitudes and behaviours.

Instead of only relying on the engagement/disengagement dichotomy to plan interventions, managers can plan the appropriate interventions depending on the specific disengagement state analysed through personal and job thrust.

The newly developed model of work states explains the fluctuation of an individual across different work states and links the personal and job-related demand–resource balance at the workplace with distal work-related outcomes, thereby significantly extending the JD-R model.

The purpose of this paper is to delve into some of the key internal and external factors that led to the choice of specific strategies for union revitalization using the theoretical framework built upon framing perspectives, the strategic action field (SAF), and the strategic choice theory.

The authors used a stringent definition and corresponding operationalization of trade union revitalization. The present research has been carried out on a registered industrial union within the context of Global South, specifically in India.

Evidence was found for the trade union adopting a mix of strategies for revitalization, namely, union organizing, social movement unionism, and union restructuring. A mix of both internal and external factors identified informed the choice of revitalization strategies.

Specific limitations include the subjectivity of the inference in spite of taking due precautions, and lack of generalizability of the findings based on a single case study.

A strong identity, coupled with structural vitality and optimum use of resources enables trade unions to frame the need of a strategy for revival in order to counter the strategic action of employers resulting in union revitalization.

The theoretical novelty of this research stems from the amalgamation of collective action frames, SAF, and strategic choice framework to understand the union revitalization in the context of Global South.

This paper uses the Social Identity Model of Collective Action (SIMCA) framework of Zomeren et al. (2008) to explain the organising experiences of the informal sector workers engaged in large number in the world's largest shipbreaking industry located in the western Indian town of Alang.

A single case study approach was adopted to understand the participation of shipbreaking workers in their trade union and factors that influence their participation.

Sense of cohesive collective identity and injustice alongside efficacy considerations have shaped the organising experiences and affected the participation of informal sector workers in their union. The trade union was able to overcome the scourge of invisibility that has been one of the dominant features of informal sector employment.

This paper treated union participation as unidimensional. Besides, the subjective conceptualization of strengths of perceptions of injustice, identities and efficacy considerations could be a limitation. The paper does acknowledge the gendered nature of shipbreaking but have not actively pursued it as a part of our research.

The findings of our study are an exemplar for those who intend to organise informal sector workers, especially precarious workers. The empirical findings allude to the role of trade unions in combating the invisibility, which is one of the defining features of informal sector workers through a distinctive, cohesive identity inculcated in those workers.

This paper has borrowed the SIMCA framework to explore union participation. Organising experiences of precarious workers from the developing world provides a contextual and an empirical novelty to our study.

Over the period, the role of finance has emerged significant in the socio-economic development of the women. There are two major types of finances, i.e. formal and informal ones. Thus, the purpose of this paper is to investigate first the determinants of the demand for credit and then the demand for these credit sources by women especially in urban slums.

In this study, a primary survey was conducted with the help of a structured questionnaire in slums of two major urban cities in India, i.e. Delhi and Mumbai. In total, 450 individuals were interviewed in each city.

This paper presents a range of significant socio-economic factors affecting the demand for credit and source of credit by women borrower in Delhi and Mumbai. Despite, the greater emphasis by the government to increase the formal credit utilization, the informal credit is still preferred.

The outcomes of the study are expectedly useful to various policymakers and banks in encouraging women to opt more for the formal credit. The government can follow the research outcomes to scale up the programmes and schemes targeted for women empowerment in urban slums.

The study is unique of its kind in doing a comparative analysis in slums of two differently located urban cities with large slum population.

This study aims to investigate and present the tribological behaviour of recursively friction stir processed 7075 aluminium alloy.

In this work, aluminium 7075 alloy is friction stir processed recursively by varying the tool rotational speed, traverse speed and the number of passes. Wear pins for testing were extracted from the processed zone and the surfaces were prepared. Wear tests were conducted as per the standard on a pin-on-disc wear testing machine at constant testing conditions and the corresponding tribological properties were analysed. The worn surface and the debris were analysed using a field-emission scanning electron microscope with energy dispersive spectroscopy analysis and elemental mapping to identify the mode of wear mechanism.

The experimental results indicate that the specimen fabricated at 1,150 rpm of tool rotation speed and 60 mm/min of traverse speed with 4 passes had the highest wear resistance and the minimum friction coefficient.

This paper details the effect of recursive friction stir processing on the surface of AA 7075 to improve the tribological properties.

The demand for aluminium alloys has been increasing in almost all the fields. In this study, the friction stir welding (FSW) of similar aluminium alloy AA 8011-h14 has been presented using three levels of tool rotational speed (n), tool tilt angle (ϴ) and tool feed (f). The purpose of this paper is to study the effect of welding parameters on various properties and time-temperature plots.

FSW was carried out using the L-9 orthogonal array of welding parameters generated using the Taguchi approach. Visual inspection and radiography testing were conducted to detect the surface and volume defects, respectively. Taguchi analysis was carried out to get optimised welding parameters for tensile testing. The microstructural analysis was carried out for the specimen possessing maximum tensile strength and the obtained grain structures were compared with the microstructure results of the base material. The peak process temperatures were noted and time-temperature plots were analysed for the varying parameters. The maximum value of hardness was recorded and analysed.

Visual inspection and radiography testing confirmed defect-free joints. The maximum tensile strength achieved was 84.44 MPa with 64.95 per cent efficiency. The optimised parameters obtained using Taguchi analysis for tensile testing were 1,500 rpm, 1° and 50 mm/min. Microstructure analysis for the specimen possessing maximum tensile strength revealed fine and equiaxed grains in the nugget zone. Time-temperature plots suggested the maximum temperature of 389 °C on the advancing side. A maximum hardness value of 36.4 HV was obtained in the nugget zone.

As per the knowledge of the authors, this study is the first attempt for the detailed experimental analysis on the FSW of this particular aluminium alloy AA 8011-h14.

The RZ5 mg alloy is used in automotive and aerospace applications including helicopter gearboxes and aircraft components. These components are prone to the wear as per the demands. The present work is the study of the significance of hard particle/ceramic, i.e. titanium carbide (TiC) in RZ5 mg alloy to protect the machine components from wear.

The abrasive wear analysis of in-situ RZ5-TiC magnesium matrix composite is considered for the study. The primary focus of the present work is to analyze the effects of varying control parameters, i.e. Wt.% of TiC, sliding distance and applied load on the responses, i.e. weight loss and coefficient of friction. Full factorial design of the experiment based on statistical analysis is used.

It is observed that the individually Wt.% of TiC and sliding distance show the comparatively significant effect on both responses. Similarly, the interaction between sliding distance and Wt.% of TiC indicated the considerable impact on weight loss. The regression equations are developed and validated for estimating responses. It is observed that the percentage errors are not appearing more than 10 per cent of responses. Therefore, the close agreement between measured and predicted values shows the adequacy of the model. The control factor is optimized using multi-response optimization. The variations of the order of 2.47 and 2.35 per cent in target value of the coefficient of friction and weight loss are achieved.

The current manuscript provides a detailed abrasive wear statistical analysis of RZ5-TiC composite. The influence of control parameters on the responses using the full factorial design, the main effect plots and interaction effects are presented.

This paper tests and validates a conceptual model linking the attachment points, team identification, attitude towards the team sponsors and the behavioural intentions in the context of Indian Premier League (IPL), while testing for the moderating effects of age and gender.

Data were collected from 1,053 participants through both online and offline survey and then analyzed using exploratory factor analysis (EFA) and structural equation modelling (SEM).

Attachment points influence the formation of team identification, which, in turn, affect the attitude towards the team sponsors. Attitude towards the team sponsors influence the behavioural intentions. Player attachment influences team identification the most. Age and gender have a moderating effect on the constructs of the study. Team identification in females is stronger because of attachment to sports, whereas males have stronger team identification based on player attachment. Males have a stronger intention to spread positive word of mouth (WOM) about sponsor products as compared to the female respondents. The younger age group of less than 21 years has more intention to spread positive WOM compared to the other age groups considered in the study.

This study contributes towards sports sponsorship research and the paradigms of social identity and attachment theories. Moreover, it will also help the marketers (sponsors) in IPL to strategically market their brands.

This is the first study to investigate the impact of attachment points on sponsorship outcomes in the context of IPL. Further, it is also the first to investigate the purchase intentions and WOM for the team sponsors in IPL. The multi-group analysis results will provide insights into marketers to better understand IPL viewers' segments and their behaviour.
