The relevance of operations research cannot be overemphasized, as it provides the best possible results in any given circumstance, through analysis of operations and the use of scientific method thus, this paper explore the combination of two operations research models (analytic hierarchy process and Markov chain) for solving subscribers’ churn and retention problem peculiar to most service firms. A conceptual model for unraveling the problem customer churn and retention decision management was proposed and tested with data on third level analysis of AHP for determining appropriate strategies for customer churn and retention in the Nigeria telecommunication industries. A survey was conducted with 408 subscribers; the sample for the study was selected through multi-stage sampling. Two analytical tools were proposed for the analysis of data. These include: Expert Choice/Excel Solver (using Microsoft Excel) and Windows based Quantitative System for Business (WinQSB). This paper plays important role in understanding various strategies for effective churn and retention management and the ranking of churn and retention drivers in order of importance to stakeholders` decision-making. The study provided a framework for understanding the application of AHP and Markov chain for modeling, analysing and proffering solution to problem of churn and retention. The study recommends organizational strategies (corporate, business and functional) that reverse the churn alternatives with high priority and equally strengthen service delivery on high priority retention alternatives in order to ensure firms sustainable competitive advantage. An erratum to this article has been published as https://doi.org/10.5195/emaj.2017.131.

Starting Point

We present a literature review on quality and operations management problems in food supply chains. In food industry, the quality of the food products declines over time and should be addressed in the supply chain operations management. Managing food supply chains with operations management methods not only generates economic benefit, but also contributes to environmental and social benefits. The literature on this topic has been burgeoning in the past few years. Since 2005, more than 100 articles have been published on this topic in major operations research and management science journals. In this literature review, we concentrate on the quantitative models in this research field and classify the related articles into four categories, that is, storage problems, distribution problems, marketing problems, and food traceability and safety problems. We hope that this review serves as a reference for interested researchers and a starting point for those who wish to explore it further.

Relevant Factors

Section 164(3) of the Tax Administration Act No. 28 of 2011 gives a senior SARS official the discretion to suspend the payment of disputed tax or a portion thereof, having regard to relevant factors. Limited guidance is available in this regard. The objectives are to establish the concerns and uncertainties regarding the relevant factors and to determine whether a ‘suspension of the payment of disputed tax’ in terms of section 164(3) constitutes the granting of ‘credit’ in terms of a ‘credit agreement’ in terms of the National Credit Act, Act No. 34 of 2005. This is achieved by adopting an explanatory research approach and performing a literature review and comparative analysis respectively. The conclusion is reached that the current factors listed are not necessarily the most relevant ones. Recommendations are made to simplify the process and to revise and improve the wording regarding the relevant factors.

Intervention Reporting

BACKGROUND In healthcare, using game-based intervention approaches to increase motivation, engagement, and overall sustainability of health behaviors is steadily becoming more common. The most prevailing approaches for such game-based interventions in healthcare research are gamification and serious games. Various researchers have discussed substantial conceptual differences between these two concepts, supported by empirical studies showing differences in the effects on specific health behaviors. However, researchers also frequently report cases where terms related to these two concepts are used ambiguously or even interchangeably. It remains unclear to which extent existing healthcare research explicitly distinguishes between gamification and serious games and whether it draws on existing conceptual considerations in order to do so. OBJECTIVE Our study aims to address this lack of knowledge by capturing the current state of conceptualizations of gamification and serious games in healthcare research. Furthermore, we provide tools for researchers to disambiguate reporting on game-based interventions. METHODS We employed a 2-step research approach. First, we conducted a systematic literature review of 206 studies published in the Journal of Medical Internet Research and its sister journals containing terms related to either gamification, serious games, or both. We analyzed their conceptualizations of gamification and serious games, as well as distinctions between the two concepts. Second, based on the literature review findings, we developed a set of guidelines for researchers reporting on game-based interventions and evaluated them with a group of 7 experts from the field. RESULTS Our results show that less than half of concept mentions are accompanied by an explicit definition. For the distinction between the two concepts, we identified 4 common approaches: implicit distinction, synonymous use of terms, serious games as gamified systems, and distinction based on the full game dimension. Our Game-based Intervention Reporting Guidelines (GAMING) consist of 25 items grouped into 4 topics: (1) Conceptual Focus, (2) Contribution, (3) Mindfulness about Related Concepts, and (4) Individual Concept Definitions. CONCLUSIONS Conceptualizations of gamification and serious games in healthcare literature are strongly heterogeneous, leading to conceptual ambiguity. Following the GAMING guidelines can support authors in rigorous reporting on study results of game-based interventions.

Practical Implications

Purpose – The purpose of this paper is to establish a readiness for entrepreneurship theoretical framework. The paper marks the first of three stages to build a scale to measure readiness for entrepreneurship. Design/methodology/approach – The current paper is conceptual. The research approach consists of formulating proposals and definitions based on an extensive literature review. Findings – The literature review reveals that no such readiness for entrepreneurship measurement tool exists. The literature review also yields definitions and components of key concepts for the theoretical framework. Research limitations/implications – The paper offers a new, holistic perspective of readiness for entrepreneurship. This research addresses measurement of readiness for entrepreneurship from a rigorous, scientific approach. The main limitation lies in capturing and organizing extensive information on topics from diverse disciplines (i.e. sociology, psychology, and business management). Practical implications – This theoretical framework enables the design and creation of a scale to measure readiness for entrepreneurship. The literature review confirmed the possibility of building such a measurement scale. Social implications – A complex tool able to identify and measure readiness for entrepreneurship would be applicable in numerous situations including the following: determining entrepreneurial abilities, analyzing potential for entrepreneurship, simulating organizational transformations, and evaluating investment recommendations. Originality/value – No holistic, scientifically grounded tool to measure readiness for entrepreneurship exists, yet there are numerous entrepreneurial capacity tests with no rigorous scientific grounding. As a remedy, this paper provides solid scientific foundations upon which to develop an instrument for measuring readiness for entrepreneurship.
