Published: August 2021

This case, along with its B case (UVA-QA-0865), is an effective vehicle for introducing students to the use of machine-learning techniques for classification. The specific context is predicting customer retention based on a wide range of customer attributes/features. The specific techniques could include (but are not limited to): regressions (linear and logistic), variable selection (forward/backward and stepwise), regularizations (e.g., LASSO), classification and regression trees (CART), random forests, graduate boosted trees (xgboost), neural networks, and support vector machines (SVM).The case is suitable for an advanced data analysis (data science, machine learning, and artificial intelligence) class at all levels: upper-level business undergraduate, MBA, EMBA, as well as specialized graduate or undergraduate programs in analytics (e.g., masters of science in business analytics [MSBA] and masters of management analytics [MMA]) and/or in management (e.g., masters of science in management [MScM] and masters in management [MiM, MM]).The teaching note for the case contains the pedagogy and the analyses, alongside the detailed explanations of the various techniques and their implementations in R (code provided in Exhibits and supplementary files). Python code, as well as the spreadsheet implementation in XLMiner, are available upon request.
Strategic improvisation: an introductory conceptual framework
Authors: Mamédio Diórgenes Falcão , Cunha Miguel Pina e , Meyer Jr Victor 
Published: August 2021

PurposeBy exploring “what is strategic improvisation in organizations?” the authors respond to advances in strategic improvisation (SI) conceptualization with an emphasis on the challenges of combining unplanned but deliberate responses to relentlessly changing environments, in which strategy becomes increasingly improvised.Design/methodology/approachAn integrative review was conducted with the potential to develop new theoretical approaches to research problems. This literature review resulted in an introductory SI framework.FindingsThe authors propose a SI conceptual framework combining foundation, structuration and capillarization. While foundations comprise extemporaneity, novelty and intentionality, considered as triggers for the manifestation of SI, in this study structuration refers to the combination of a minimal structure and a reassessment process in response to unexpected situations. Capillarization means interaction patterns characterized as spontaneous, dynamic and collaborative. This framework leads to the definition of SI as an impromptu deliberate action stream, combining unplanned responses with intentional actions sustaining the convergence of strategy and operation, to integrate and reconfigure resources at the strategic level.Practical implicationsSI in practice considers reconfiguring the internal and external forces to deal with unexpected events and impromptu deliberate responses to face rapidly changing environments. This would enable practitioners and managers to prepare for eventualities that evolve dynamically and spontaneously, and unpredictable imminent global crises.Originality/valueThe authors conducted the first study mapping improvisation as a strategic organizational level phenomenon. SI is recognized as operating across levels, from the tactical and functional to the strategic.
How do personal values help to build generation Y’s entrepreneurial intentions? The role of gender differences
Authors: Ettis Saïd Aboubaker 
Published: August 2021

Purpose
The purpose of this paper is to assess the extent to which personal values affect entrepreneurial intentions and the extent to which this relationship depends on gender among the millennial generation.

Design/methodology/approach
This relationship was examined using the list of values (LOV). Based on a sample of 600 respondents born between 1977 and 1994, a self-administered online questionnaire was conducted.

Findings
The partial least squares structural equation modeling (PLS-SEM) approach demonstrated that Generation Y members who give higher priority to self-direction, social affiliation and hedonic orientation values have greater entrepreneurial intentions. Across gender, the PLS-multigroup analysis (MGA) approach reveals that self-direction values enhance entrepreneurial intention for Generation Y females but not for males. Social affiliation values improve entrepreneurial intention for Generation Y males but not for females. Hedonic orientation values rise entrepreneurial intentions for both Generation Y males and females similarly. The findings give also a ranking of the nine LOV.

Research limitations/implications
Across-cultural comparisons are lacking in this research. This study only focuses on the value–intention relationship. Future research could study the value–attitude–behavior.

Practical implications
The results provide implications to all agents concerned by promoting new enterprises and feminine entrepreneurship regarding the implementation of personal values in fostering the venture creation process and stimulation of people to become business owners.

Originality/value
Little is known about the role of personal values in venture creation. The findings provide support for the role personal values play in building entrepreneurial intentions. The focus here was on Generation Y. The generation that faces problems of unemployment, job loss and poverty specifically in the time of crises of the COVID-19 pandemic. The value-based entrepreneurship approach is a proliferating field of research as the world seeks to rebuild economies.
MHD convective process due to rotation of cylinders and movement of a wavy wall of two-sided wavy enclosures with radiation
Authors: Ahmed Sameh E. , Alhazmi Muflih 
Published: August 2021

Purpose
This paper aims to study the mixed convective process due to various dynamics, namely, inner rotating cylinders and upper-wavy wall movement for the first time.

Design/methodology/approach
The Galerkin finite element method together with the characteristic-based split scheme is applied to solve the governing system.

Findings
The main outcomes revealed that the direction of the rotation of the cylinders, radius and locations of the rotating shapes are beneficial controlling elements for the enhancement of heat transfer. Also, for all the considered cases, values of the Bejan number indicate that the fluid friction irreversibility is dominance compared to the heat transfer irreversibility. Further, average values of the heat transfer entropy, fluid friction entropy and total entropy are minimized in the case of fixed cylinders regardless of the cylinder radius.

Originality/value
The authors are interested in the mixed convection case due to regular boundaries and hence this simulation purposes a first attempt to examine the mixed convective flow due to irregular wavy boundaries. This study considered various dynamics, namely, inner rotating cylinders and wavy-lid driven wall which makes it more attractive to the readers. Various cases based on radius of the cylinder and direction of the rotations together with several locations of the rotating shapes are taken into account which makes the current simulation is comprehensive. Various studies presented in this field are made by commercial software and these treatments need special conditions (having limitation) but the current solution methodology is based on a finite element method home-code. Various important impacts, are, also, examined, namely, inclined geometry, inclined magnetic field, thermal radiation and heat generation/absorption. The entropy of the current complex system is analyzed based on the second law of thermodynamics.
The local meshless collocation method for solving 2D fractional Klein-Kramers dynamics equation on irregular domains
Authors: Abbaszadeh Mostafa , Pourbashash Hossein , Khaksar-e Oshagh Mahmood 
Published: August 2021

Purpose
This study aims to propose a new numerical method for solving non-linear partial differential equations on irregular domains.

Design/methodology/approach
The main aim of the current paper is to propose a local meshless collocation method to solve the two-dimensional Klein-Kramers equation with a fractional derivative in the Riemann-Liouville sense, in the time term. This equation describes the sub-diffusion in the presence of an external force field in phase space.

Findings
First, the authors use two finite difference schemes to discrete temporal variables and then the radial basis function-differential quadrature method has been used to estimate the spatial direction. To discrete the time-variable, the authors use two different strategies with convergence orders

O(τ1+γ) and

O(τ2−γ) for 0 < γ < 1. Finally, some numerical examples have been presented to show the high accuracy and acceptable results of the proposed technique.

Originality/value
The proposed numerical technique is flexible for different computational domains.
A cost-minimizing approach to eliminating the primary sources of greenhouse gas emissions at institutions of higher education
Authors: Timmons David S. , Weil Benjamin 
Published: August 2021

Purpose
Many institutions of higher education have committed to carbon neutrality. Given this goal, the main economic issue is minimizing cost. As for society as a whole, dominant decarbonization strategies are renewable electricity generation, electrification of end uses and energy efficiency. The purpose of this paper is to describe the optimum combination of strategies.

Design/methodology/approach
There are four questions for eliminating the primary institutional greenhouse gas emissions: how much renewable electricity to produce on-site; where and at what price to purchase the balance of renewable electricity required; how to heat and cool buildings without fossil fuels; and how much to invest in energy efficiency. A method is presented to minimize decarbonization costs by equating marginal costs of the alternates.

Findings
The estimated cost of grid-purchased carbon-free energy is the most important benchmark, determining both the optimal level of campus-produced renewable energy and the optimum efficiency investment. In the context of complete decarbonization, greater efficiency investments may be justified than when individual measures are judged only by fossil-fuel savings.

Practical implications
This paper discusses a theoretically ideal plan and implementation issues such as purchasing carbon-free electricity, calculating marginal costs of conserved energy, nonmarginal cost changes, uncertainty about achieving efficiency targets, and dynamic pricing. The principles described in this study can be used to craft a cost-minimizing decarbonization strategy.

Originality/value
While previous studies discuss decarbonization strategies, there is little economic guidance on which strategies are optimal, on how to combine strategies to minimize cost or how to identify a preferred path to decarbonization.
A bibliometric analysis of mobile learning in the education sector
Authors: Khan Farheen Mujeeb , Gupta Yuvika 
Published: August 2021

Purpose
This study aims to contribute to literature on mobile learning (m-learning) by proposing four research clusters whereby scholars can expand m-learning research to facilitate effective learning experiences for students.

Design/methodology/approach
This study reviews student-centric literature on m-learning since 2010 and presents insights on m-learning while applying well-established bibliometric techniques. Consequently, 722 articles published in the past decade were evaluated by identifying key research areas, most influential authors, countries, journals and organisations. Most influential studies based on number of citations were also examined.

Findings
Through article co-citation analysis, four clusters representing m-learning literature were identified: concept of m-learning, application of m-learning in education, designing framework for model learning/acceptance and emerging technologies.

Originality/value
As mobile learning (m-learning) has undergone an evolution from being an emerging field to a significant teaching and research tool, it is pertinent to explore and identify the trends of m-learning research.
Antecedent of lack of proficiency and the need for an automated financial plan for the course entrepreneurship creativity and innovation
Authors: Thottoli Mohammed Muneerali 
Published: August 2021

PurposeThis study aims to analyze antecedents of students’ lack of proficiency (in preparing financial statements, cash flow statements, cost volume profit analysis and budgeting) and the need for an automated financial plan (AFP) for the course entrepreneurship creativity and innovation within Higher Educational Institutions (HEIs) in Oman.Design/methodology/approachThe study used a set of four instrument items containing questionnaires to measure the variables in this study. A cross-sectional study was carried out at various universities and colleges in Oman during the year 2020, comprising 174 students from different majors. The results were analyzed using structural equation modelling-partial least squares.FindingsThe findings of the study suggest that the students in the universities and colleges should be educated and facilitated to enable them to gain more knowledge in finance/accounting through an AFP and, thus, warrants preparation of fair financial estimation for their innovative business project. A majority of students strongly support the need for implementing an AFP for their compulsory course, entrepreneurship creativity and innovation in HEIs in Oman.Research limitations/implicationsThis research is restricted to AFPs for the students in Oman who study the course entrepreneurship creativity and innovation. It is recommended that future study may extend to automated business plans for the students to improve their practical knowledge pertinent to the readiness of Omani students, as well as to give material transformation of internal environments in HEIs.Practical implicationsUnique AFP for university and college students for their compulsory course, entrepreneurship creativity and innovation provide important resources for policymakers responsible for HEIs, allowing them to improve the quality of preparing a financial plan for their innovative business ideas and new business start-ups.Originality/valueThere has been little discussion about the need for an AFP for the students who study the course entrepreneurship creativity and innovation. This study analyzes accounting standards as antecedents about students’ lack of proficiency towards an AFP for the course entrepreneurship creativity and innovation of universities and colleges in Oman which tries to fill this gap in the existing research. Hence, this study is considered as a novel approach that has not been broadly discussed in the earlier research.
The ethical implications of 4IR
Authors: Peckham Jeremy Burford 
Published: August 2021

Purpose
This paper aims to highlight the ethical implications of the adoption of Fourth Industrial Revolution (4IR) technologies, particularly artificial intelligence (AI), for humanity. It proposes a virtues approach to resolving ethical dilemmas.

Design/methodology/approach
The research is based on a review of the relevant literature and empirical evidence for how AI is impacting individuals and society. It uses a taxonomy of human attributes against which potential harms are evaluated.

Findings
The technologies of the 4IR are being adopted at a fast pace, posing numerous ethical dilemmas. This study finds that the adoption of these technologies, driven by an Enlightenment view of progress, is diminishing key aspects of humanity – moral agency, human relationships, cognitive acuity, freedom and privacy and the dignity of work. The impact of AI algorithms is also shown, in particular, is shown to be distorting the view of reality and threatening democracy, in part due to the asymmetry of power between Big Tech and users. To enable humanity to be masters of technology, rather than controlled by it, a virtues-based approach should be used to resolve ethical dilemmas, rather than utilitarian ethics.

Research limitations/implications
Further investigation is required to provide more empirical evidence of the harms to humanity of some 4IR technologies cited, such as virtual and augmented reality, manipulative algorithms and toy robots on children and adults and the reality of re-skilling where jobs are lost through automation.

Practical implications
This paper provides a framework for evaluating the impact of some 4IR technologies of humanity and an approach to resolving ethical dilemmas.

Social implications
Most of the concerns surrounding 4IR technologies, and in particular AI, tend to focus on human rights issues. This paper shows that there are other significant harms to what it means to be a human being from 4IR technologies that will have a profound impact on society if not adequately addressed.

Originality/value
The author is not aware of any other work that uses taxonomy of AI applications and their different impacts on humanity. The proposal to use virtues as a means to resolve ethical dilemmas is also novel in regard to AI.
Job evaluation as a mechanism for achieving the fairness of a wage structure in the administrative system: theoretical perspectives
Authors: El Balshy Suzan Abd El Moneim , Ismael Mamdouh 
Published: August 2021

PurposeThis paper aims to present a theoretical framework which reveals the relationship between job evaluation (JE) and the development of fair wage structure from the organizational justice (OJ) perspective. It focuses on analyzing the dimensions of job-based pay structure and the use of multifaceted construct of OJ (procedures, distribution and interaction) to determine how the perceived justice of JE's multi-levels construct contributes to achieve the fairness of wage structure.Design/methodology/approachThis paper adopts an analytical descriptive approach in terms of explaining the perspectives and viewpoints related to the analysis. This paper is based on examining a theoretical framework provided by the authors based on a theoretical review of literature and a set of empirical evidences.FindingsThe design of a hierarchical wage structure counts on the multidimensional approach of JE which consists of three dimensions (processes, outcomes and social system). In addition, the determination of wage structure fairness is dependent on the assessment of the perceived justice of: JE's procedures, wages distribution and management's treatment with its employees.Originality/valueThis study provides a new theoretical contribution in studying the relationship between JE and the design of fair wage structure. This contribution can be regarded as a theoretical foundation for conducting some empirical and comparative studies in the future. The study affords directive mechanisms to policymakers in order to enhance the fairness of the wage structure across the state.

Authors: Lestari Fitra , Kurniawan Rahmad , Arifin Johar , Yasir Muhammad , Muhammad Saleh Mawardi , Akbarizan  
Published: August 2021

Purpose
Nowadays, the Good Manufacturing Practice (GMP) in Indonesia with the product’s need for halal certification is limited. The purpose of this paper is to measure the integrated framework of Halal Good Manufacturing Practices (HGMP) in small and medium-sized enterprises (SMEs) and to discover the effect of its performance in the food sector.

Design/methodology/approach
This research conducted focus group discussion in 2 locations with 8 experts and 73 SMEs in the food sector at 2 Indonesian Government agencies.

Findings
The study indicated 6 variables and 40 indicators on HGMP and its implementation in each agency. Two agencies in this research were categorized as poor, which indicated the need to increase the implementation of HGMP. For the SMEs’ business process policy, there were significantly different variables in the building, employee, storage and maintenance.

Research limitations/implications
The implementation of the HGMP is examined in this research based on government regulation. It has not been thoroughly tested based on consumer responses. Furthermore, it can consider consumer satisfaction in the halal framework of GMP.

Practical implications
Government agencies in Indonesia can measure the implementation of HGMP in food sector SMEs and guide SMEs to achieve halal quality standards.

Originality/value
This research provides an integrated framework for measuring HGMP in SMEs guided by the Indonesian Government’s agency in meeting the standard of halal products.
On the relationship between policy uncertainty and sustainable investing
Authors: Shaikh Imlak 
Published: August 2021

Purpose
In recent times, sustainable investment gaining much attention within the investors’ community and it is broadly driven by environmental, social and governance (ESG) factors. This study aims to examine the ESG-based sustainability index and economic policy uncertainty (EPU).

Design/methodology/approach
Corporate sustainability assessment procedure yields Dow Jones sustainability indexes (DJSIUS) and ESG compliant firms become a member of such indexes. To uncover the effects of policy uncertainty as follows: the study considers EPU index, equity market policy uncertainty index, economic and political events for the period 2000–2017. The authors present the study using a conditional volatility framework.

Findings
The correlation between the DJSIUS and policy uncertainty appears to be negative and statistically significant. It is apparent from the results that policy uncertainty does contain important ESG factors that explain the sustainable investment in US firms. Moreover, the stock market boom, credit crunch, Lehman collapse and fiscal crises have shown significant adverse effects on the sustainability index. More importantly, it is seen that investors’ sustainable investing considers presidential election years for portfolio planning; the uncertainty associated with the election years has also shown a negative impact on the sustainable returns.

Practical implications
First, sustainability is essential for the long-term stakeholders’ wealth maximization under governments’ policy uncertainty such as constrained resources, demographic and climate-change-policy, societal expectations, public-policies, regulatory structure. Second, EPU creates new opportunities and risks for sustainable firms and sustainable investing.

Originality/value
The study is novel in which the authors present the effects of uncertainty on socially responsible investing.
