Abstract

Purpose

In recent years, data science has become a high-demand profession, thereby attracting transmuters (individuals who want to change their profession due to industry trends) to this field. The primary purpose of this paper is to guide transmuters in becoming data scientists.

Design/methodology/approach

An exploratory study was conducted to uncover the challenges faced by data scientists according to their educational backgrounds. An extensive set of responses from 31 countries was received.

Findings

The results reveal that skill requirements and tool usage vary significantly with educational background. However, regardless of differences in academic background, the data scientists surveyed spend more time analyzing data than operationalizing insight.

Research limitations/implications

The collected data are available to support replication in various scenarios, for example, for use as a roadmap for those with an educational background in art-related disciplines. Additional empirical studies can also be conducted specific to geographical location.

Practical implications

The current work has categorized data scientists by their fields of study making it easier for universities and online academies to suggest required knowledge (courses) according to prospective students' educational background.

Originality/value

The conducted study suggests the required knowledge and skills for transmuters to acquire, based on their educational background, and reports a set of motivational factors attracting them to adopt the data science field.

Abstract

Purpose

Similarly, Zhu et al. (2014) and Zhang et al. (2014) stated that addressing privacy concerns with the recommendation process is necessary for the healthy development of app recommendation. Recently, Xiao et al. (2020) mentioned that a lack of effective privacy policy hinders the development of personalized recommendation services. According to the reported work, privacy protection technology methods are too limited for mobile focusing on data encryption, anonymity, disturbance, elimination of redundant data to protect the recommendation process from privacy breaches. So, this situation motivated us to conduct a systematic literature review (SLR) to provide the viewpoint of privacy and security concerns as mentioned in current state-of-the-art in the mobile app recommendation domain.

Design/methodology/approach

In this work, the authors have followed Kitchenham guidelines (Kitchenham and Charters, 2007) to devise the SLR process. According to the guidelines, the SLR process has three main phases: (1) define, (2) conduct the search and (3) report the results. Furthermore, the authors used systematic mapping approach as well to ensure the whole process.

Findings

Based on the selected studies, the authors proposed three main thematic taxonomies, including architectural style, security and privacy strategies, and user-usage in the mobile app recommendation domain. From the studies' synthesis viewpoint, it is observed that the majority of the research efforts have focused on the movie recommendation field, while the mainly used privacy scheme is homomorphic encryption. Finally, the authors suggested a set of future research dimensions useful for the potential researchers interested to perform the research in the mobile app recommendation domain.

Originality/value

This is an SLR article, based on existing published research, where the authors identified key issues and future directions.

Abstract

Purpose

This study aims to identify the developer’s objectives, current state-of-the-art techniques, challenges and performance evaluation metrics, and presents outlines of a knowledge-based application programming interfaces (API) recommendation system for the developers. Moreover, the current study intends to classify current state-of-the-art techniques supporting automated API recommendations.

Design/methodology/approach

In this study, the authors have performed a systematic literature review of studies, which have been published between the years 2004–2021 to achieve the targeted research objective. Subsequently, the authors performed the analysis of 35 primary studies.

Findings

The outcomes of this study are: (1) devising a thematic taxonomy based on the identified developers’ challenges, where mashup-oriented APIs and time-consuming process are frequently encountered challenges by the developers; (2) categorizing current state-of-the-art API recommendation techniques (i.e. clustering techniques, data preprocessing techniques, similarity measurements techniques and ranking techniques); (3) designing a taxonomy based on the identified objectives, where accuracy is the most targeted objective in API recommendation context; (4) identifying a list of evaluation metrics employed to assess the performance of the proposed techniques; (5) performing a SWOT analysis on the selected studies; (6) based on the developer’s challenges, objectives and SWOT analysis, presenting outlines of a recommendation system for the developers and (7) delineating several future research dimensions in API recommendations context.

Research limitations/implications

This study provides complete guidance to the new researcher in the context of API recommendations. Also, the researcher can target these objectives (accuracy, response time, method recommendation, compatibility, user requirement-based API, automatic service recommendation and API location) in the future. Moreover, the developers can overcome the identified challenges (including mashup-oriented API, Time-consuming process, learn how to use the API, integrated problem, API method usage location and limited usage of code) in the future by proposing a framework or recommendation system. Furthermore, the classification of current state-of-the-art API recommendation techniques also helps the researchers who wish to work in the future in the context of API recommendation.

Practical implications

This study not only facilitates the researcher but also facilitates the practitioners in several ways. The current study guides the developer in minimizing the development time in terms of selecting relevant APIs rather than following traditional manual selection. Moreover, this study facilitates integrating APIs in a project. Thus, the recommendation system saves the time for developers, and increases their productivity.

Originality/value

API recommendation remains an active area of research in web and mobile-based applications development. The authors believe that this study acts as a useful tool for the interested researchers and practitioners as it will contribute to the body of knowledge in API recommendations context.

Abstract

Purpose

In this global era every organization aims to retain its key workers through salary, incentives, rewards and recognition. Organizational learning culture and leaders' support are amongst those aspects that have not been focused on extensively by organizations to retain their key employees. The present study aims to investigate the relationship between organizational learning culture, leader‐member exchange quality, organizational commitment and turnover intention.

Design/methodology/approach

A total of 415 employees working in Malaysian banks were approached on the basis of convenience sampling. Respondents were asked about leader‐member exchange, organizational learning culture, organizational commitment and their intention to leave the organization through a questionnaire‐based survey.

Findings

Leader‐member exchange, organizational learning culture and organizational commitment are found to correlate with each other. Furthermore, structural equation modeling confirms that organizational commitment performs the role of mediator between organizational learning culture and turnover intention.

Research limitations/implications

HR managers should know the importance of leaders' support and learning environment, as these affect employees' level of commitment, which ultimately reduces their intentions to leave the organization. Limitations are also discussed.

Originality/value

The current study elucidates the importance of learning culture for both employers and employees. It produces several unique findings and managerial takeaways for building a better organizational environment for employees to learn and stay with the organization.

Abstract

Purpose

The purpose of this paper was to investigate the relationship among organizational learning culture (OLC), psychological empowerment (PE), job satisfaction, affective organizational commitment and turnover intention, as very little has been conducted in this regard.

Design/methodology/approach

A quantitative research design was used via a questionnaire among 412 Malay-Chinese working in the banking and insurance sector of Malaysia.

Findings

OLC and PE were found to influence positively on job satisfaction and affective commitment, but negatively on turnover intention. In addition, job satisfaction was found to perform the role of mediator.

Research limitations/implications

The study used self-reported data based on cross-sectional survey.

Practical implications

OLC and PE were found to influence affective commitment and turnover intention directly and indirectly, providing an avenue of approach for managers to retain their key employees.

Originality/value

The paper examines OLC and PE as antecedents of employees’ attitudes (i.e. job satisfaction, affective commitment and turnover intention), neglected variables along with the mediation of job satisfaction.

Abstract

Purpose

Innovation has become a necessity for the information technology (IT) sector, especially during COVID-19 pandemic. Therefore, this study aims to investigate how knowledge sharing affects employees’ innovative work behavior (IWB). Specifically, the study examined occupational self-efficacy (as mediating mechanism) and entrepreneurial leadership (as boundary condition) to encourage IWB.

Design/methodology/approach

The study used social media platforms to collect data from 270 employees working in the IT sector through “google forms” on convenience basis between March and August, 2021. The study applied structural equation modeling in two stages to examine the measurement model (for uni-dimensionality) and the structural model (for hypotheses testing).

Findings

The study noted that knowledge sharing positively affects employees’ IWB and occupational self-efficacy positively explains this association. In addition, employees’ perception of entrepreneurial leadership strengthens the association between knowledge sharing and IWB.

Research limitations/implications

The study collected data from a developing country during COVID-19 by using a cross-sectional design that may restrict causality. However, the findings suggest the management not only encourages knowledge sharing environment but also engages employees in various training that motivate them to experiment with new ideas and techniques.

Originality/value

This study extends the existing literature on knowledge sharing and IWB by exploring occupational self-efficacy as mediating mechanism and entrepreneurial leadership as a boundary condition.

Abstract

Purpose

The authors examine the spillover effects of CEO removal on the corporate financial policies of competing firms among S&P 1500 firms.

Design/methodology/approach

The authors used generalized estimating equations (GEE) on a sample of S&P 1,500 firms from 2000 to 2018 to test this study's research hypotheses. Return on assets (ROA), investment policy, and payout policy are used as proxies for corporate policies.

Findings

The authors found an increase in ROA and dividend payout in the immediate aftermath. Further, this study's hypothesis does not hold for R&D expenditure and net-working capital as the authors found an insignificant change in them in the immediate aftermath. However, the authors found a significant reduction in capital expenditure, supporting this study's hypothesis in the context of investment policy. Institutional investors and product similarity moderated the spillover effect on corporate policies (ROA, dividend payout, and capital expenditure).

Originality/value

The authors address a novel aspect of CEO performance-induced removal due to poor performance, i.e., the response of other CEOs to CEO performance-induced removal. This study's findings add to the literature supporting the bright side of CEOs' response to CEO performance-induced removal in peer firms due to poor performance.

Abstract

Purpose

This study analyzes the role of supply chain ambidexterity (SC-Ambidexterity) in developing supply chain resilience (SC-Resilience). We describe SC-Ambidexterity as a simultaneous application of supply chain adaptability (SC-Adaptability) and supply chain alignment (SC-Alignment) capabilities. We also consider the role of supply chain agility (SC-Agility) in the relationship between SC-Ambidexterity and SC-Resilience. We further suggest that the relationship between SC-Ambidexterity and SC-Resilience may be stronger in case of higher market uncertainty.

Design/methodology/approach

Based on the dynamic capabilities view (DCV) of the firm, we develop a set of hypotheses that are tested through a survey of manufacturing firms in Pakistan. The hypothesized model is tested through structural equation modeling (SEM).

Findings

The results of this study show a positive effect of SC-Ambidexterity on SC-Resilience. SC-Agility positively mediates the relationship between SC-Ambidexterity and SC-Resilience. However, our results show that this relationship does not vary at different levels of environmental uncertainty.

Originality/value

This study provides the seminal operationalization of SC-Ambidexterity in the supply chain context. It further shows the importance of SC-Ambidexterity and SC-Agility in contributing toward SC-Resilience.

Abstract

Purpose

Knowledge sharing has become necessary for organizations as it is a source of competitive advantage. Therefore, this study aims to investigate how empowering leadership through psychological empowerment encourages employees’ knowledge-sharing (KS) behavior. This study further explores the moderating role of learning goal orientation (LGO) between psychological empowerment and KS behavior.

Design/methodology/approach

This study collected data from 423 employees working in manufacturing and service organizations in two waves on convenience basis to tackle common method variance. The data were analyzed through structural equation modeling.

Findings

The results revealed that empowering leadership helps employees modify their KS behavior both directly and indirectly in the presence of psychological empowerment. Moreover, individuals high in LGO are more likely to involve in KS behavior when psychologically empowered.

Research limitations/implications

This study used a cross-sectional design and suggests management focus on their working environment to enhance knowledge sharing among employees, which is possible through empowering leaders. The study further suggests management not ignore individual attributes during recruitment.

Originality/value

Drawing upon job characteristics model and social exchange theory, this study explores the mediating role of psychological empowerment between empowering leadership and KS behavior and the moderating role of LGO on the association between psychological empowerment and KS behavior.
