Abstract
Purpose
Overall, selection maps about the extent of the eutectic growth projects the solidification velocities leading to given microstructures. This is because of limitations of most of the set of results when obtained for single thermal gradients within the experimental spectrum. In these cases, associations only with the solidification velocity could give the false impression that reaching a given velocity would be enough to reproduce a result. However, that velocity must necessarily be accompanied by a specific thermal gradient during transient solidification. Therefore, the purpose of this paper is to not only project velocity but also include the gradients acting for each velocity.
Design/methodology/approach
Compilation of solidification velocity, v, thermal gradient, G, and cooling rate, Ṫ, data for Sn-Cu and Sn-Bi solder alloys of interest is presented. These data are placed in the form of coupled growth zones according to the correlated microstructures in the literature. In addition, results generated in this work for Sn-(0.5, 0.7, 2.0, 2.8)% Cu and Sn-(34, 52, 58)% Bi alloys solidified under non-stationary conditions are added.
Findings
When analyzing the cooling rate (Ṫ = G.v) and velocity separately, in or around the eutectic composition, a consensus cannot be reached on the resulting microstructure. The (v vs. G) + cooling rate diagrams allow comprehensive analyzes of the combined v and G effects on the subsequent microstructure of the Sn-Cu and Sn-Bi alloys.
Originality/value
The present paper is devoted to the establishment of (v vs. G) + cooling rate diagrams. These plots may allow comprehensive analyses of the combined v and G effects on the subsequent microstructure of the Sn-Cu and Sn-Bi alloys. This microstructure-processing mapping approach is promising to predict phase competition and resulting microstructures in soldering of Sn-Cu and Sn-Bi alloys. These two classes of alloys are of interest to the soldering industry, whereas manipulation of their microstructures is considered of utmost importance for the metallurgical quality of the product.

Abstract
Purpose
The purpose of this study is to identify the major factors influencing the adoption of health-care wearables in generation Z (Gen Z) customers in India. A conceptual framework using push pull and mooring (PPM) adoption theory was developed.
Design/methodology/approach
Data was collected from 208 Gen Z customers based on 5 constructs related to the adoption of health-care wearables. Confirmatory factor analysis and structural equation modelling was used to analyse the responses. The mediation paths were analysed using bootstrapping method and examination of the standardized direct and indirect effects in the model.
Findings
The study results indicated that the antecedent factors consisted of push (real-time health information availability), pull (normative environment) and mooring (decision self-efficacy) factors. The mooring factor (MOOR) was related to the push factor but not the pull factor. The MOOR, in turn, was related to the switching intention of Gen Z customers for health wearables adoption.
Research limitations/implications
The research study extended the literature related to the PPM theory in the context of the adoption of health wearables among Gen Z customers in India.
Practical implications
The study outcome would enable managers working in health wearable organizations to understand consumer behaviour towards health wearables.
Social implications
The use of health wearables among Gen Z individuals would lead to future generations adopting a healthy lifestyle resulting in an effective workforce and better economy.
Originality/value
This was one of the few studies which have explored the PPM theory to explore the factors for the adoption of health wearables among Gen Z customers in India.

Abstract
The focus of global training has primarily been on preparing employees to work effectively in other cultures, such as in expatriate training, acculturation training, and training for technology transfer. One issue that has been ignored is the implication of using training systems that are developed in a specific cultural context and then deployed globally. This chapter proposes a framework to show the influence of culture on one aspect of training effectiveness, the transfer of newly learned skills to the job. Specific relationships are proposed, using Baldwin and Ford’s (1988) transfer of training framework as a guide, and also by synthesizing findings from areas such as cross-cultural psychology, human resource management, education, and technology management.

Abstract
Older workers represent an increasingly important source of labour for organisations. Irrespective of age, a worker needs the appropriate skills and knowledge to be productive and to help the organisation achieve its strategic objectives. However, in many organisations, older workers are less likely to be offered training opportunities than their younger compatriots. This is due, in part, to negative stereotypical assumptions about older workers by managers. Learning and training are influenced by an individual’s career span and motivation. As a person ages, their work-related needs will change. There is a shift from growing and developing their career to a focus on security, maintenance, emotional satisfaction and mastery. Cognitive change takes place during a person’s life, and a gradual decline in primary mental abilities can be expected, but the notions of general decline are simplistic and misleading. A person is able to learn at any age and the older worker is capable of adjusting to changes in work. Many people assume that older workers are homogeneous but this is not the case. There are significant differences between older workers and these differences need to be acknowledged and understood. The organisational culture will affect learning and training opportunities for older workers, as will the attitudes of managers to older employees. Learning and training for older workers will also be influenced by the national culture and, in this chapter, selected Asian countries are discussed. The chapter concludes by offering recommendations regarding learning and training for older workers in organisations.

Abstract
Research on mentorship has been dominated by the West and little is known about the cultural variations of the mentoring phenomenon in Asian countries. A richer understanding of the cultural context that is more attuned to mentoring experience in Asia can help to improve workplace experience, in general, for those working in and for those who intend to work in the region. This chapter captures the important theoretical lenses in the mentoring literature, and also provides a clear demarcation between negative mentoring and dysfunctional mentoring. This is followed by contextualizing mentoring as per four of Hofstede's six cultural dimensions by dwelling on mentoring experience in countries such as China, India, Pakistan, Japan, South Korea and Taiwan. It is hoped that this chapter will pave the way for further research, which may be a precursor for theory development.

The purpose of this paper is to study the relationship between institutional holdings and analyst coverage in the context of the heterogeneous nature of institutional investors.
Abstract
Purpose
The purpose of this paper is to study the relationship between institutional holdings and analyst coverage in the context of the heterogeneous nature of institutional investors.
Design/methodology/approach
Similar to prior studies (e.g. Ke and Ramalingegowda; Ramalingegowda and Yu), this paper obtains institutional investors' trading classifications (transient, dedicated, and quasi‐indexing) from Brian Bushee directly. To examine the hypotheses, the paper uses a two‐step instrumental variable approach demonstrated in O'Brien and Bhushan to mitigate the simultaneity relationship between the change in analyst coverage and the change in the number of heterogeneous institutional investors.
Findings
The findings suggest that such relations are different among transient, dedicated, and quasi‐indexing institutional investors. Specifically, there are three major results. First, a change to the number of analyst coverage has the lowest impact on the change in the number of dedicated institutional investors. Second, a change in the number of transient institutional investors has a higher impact on change in analyst coverage than those for change in the number of dedicated and quasi‐indexing institutional investors. Third, changes to analysts' buy or sell recommendations have the least impact on the change in the number of dedicated institutions, relative to transient and quasi‐indexing institutions.
Research limitations/implications
The findings suggest that institutional investors are not homogeneous. Research studies on institutional investors need to disentangle the differences among different types of institutions.
Originality/value
The paper provides a comprehensive study on different institutional investors and analyst coverage. The findings show the complex nature of the interaction between institutional investors and analyst coverage.

Abstract
Purpose
This study aims to mediate the impact of workplace stress and job satisfaction on nurses’ perception of training. It sheds light on the links between job satisfaction, Certified Nursing Assistants’ perception of training and workplace stress in nursing homes.
Design/methodology/approach
A cross-sectional questionnaire was distributed in 12 different elderly home care centres in Northern Cyprus during September to October 2017. The sampling frame consists of 317 full-time Certified Nursing Assistants who completed measures of perception of training, job satisfaction and workplace stress. This paper used structural equation modelling to test a theoretical model and hypothesis.
Findings
The findings emphasize that Certified Nursing Assistants’ perception of training has a positive impact on their job satisfaction and negative impact on workplace stress while workplace stress mediates the relationship between their perception of training and job satisfaction. The results indicate that while the motivation for training and support for training have an effect on job satisfaction, access to training and benefits for training do not yield any significant impact on it and workplace stress plays a mediating role.
Originality/value
This study confirms that the CNAs’ perception of training and job stress affect the emergence of job satisfaction, and workplace stress mediated the relation between training and satisfaction posited by social exchange theory.

Abstract
Purpose
We take a state-stewardship view on corporate governance and executive compensation in economies with strong political involvement, where state-appointed managers act as responsible “stewards” rather than “agents” of the state.
Methodology/approach
We test this view on China and find that Chinese managers are remunerated not for maximizing equity value but for increasing the value of state-owned assets.
Findings
Managerial compensation depends on political connections and prestige, and on the firms’ contribution to political goals. These effects were attenuated since the market-oriented governance reform.
Research limitations/implications
Economic reform without reforming the human resources policies at the executive level enables the autocratic state to exert political power on corporate decision making, so as to ensure that firms’ business activities fulfill the state’s political objectives.
Practical implications
As a powerful social elite, the state-steward managers in China have the same interests as the state (the government), namely extracting rents that should adhere to the nation (which stands for the society at large or the collective private citizens).
Social implications
As China has been a communist country with a single ruling party for decades, the ideas of socialism still have a strong impact on how companies are run. The legitimacy of the elite’s privileged rights over private sectors is central to our question.
Originality/value
Chinese executive compensation stimulates not only the maximization of shareholder value but also the preservation of the state’s interests.

Abstract
Purpose
Knowledge sharing contributes to the success of an organization in various ways. This paper aims to summarize the findings from past research on knowledge-sharing outcomes in organizations and to suggest promising directions for future research.
Design/methodology/approach
There was a conduction of a systematic literature review that consisted of three main phases: defining a review protocol, conducting the review and reporting the review. The thematic analysis was conducted on 61 studies, based on which a framework for understanding the impacts of knowledge sharing was developed.
Findings
Previous research has investigated knowledge-sharing outcomes at three levels: the individual, team and organization; specific impacts are summarized for each level. The most commonly studied factors affected by knowledge sharing are creativity, learning and performance. Knowledge sharing is also found to have some beyond-convention work-related impacts, such as those on team climate and employees’ life satisfaction. Research on the outcomes of knowledge sharing is dominated by quantitative studies, as we found only one qualitative study in this review. Based on the discussion of the results, promising avenues for further research were identified and a research agenda was proposed. More research on differential, psychological and negative impacts, as well as interactional and methodological aspects of knowledge-sharing, is suggested.
Originality/value
To date, no systematic review has been conducted on the impacts of knowledge-sharing. This paper makes an important contribution to knowledge-sharing research, as it consolidates previous research and identifies a number of useful research topics that can be explored to advance the field, as well as to establish the evidence-based importance of knowledge sharing.
