Motivational factors, customer engagement and loyalty in the South African mobile instant messaging environment: moderating effect of application usage
Authors: Kritzinger Ronnie , Petzer Daniël Johannes 
Published: December 2020

Purpose
The purpose of this paper is to examine specific gratifications obtained from using mobile instant messaging (MIM) applications by applying the uses and gratifications theory. This study explores the relationships between motivational factors, customer engagement and loyalty for existing WhatsApp subscribers in South Africa, as well as the moderating effect of application usage.

Design/methodology/approach
A descripto-explanatory research design was used in this quantitative study and 282 responses from an online survey were analysed. Structural equation modelling was used to test the study’s hypotheses.

Findings
The study reveals that utilitarian and hedonic motivation impact customer engagement positively in using WhatsApp, which, in turn, impacts loyalty. Social motivation in using WhatsApp bore no relationship with customer engagement. Furthermore, medium application usage moderates the link between customer engagement and utilitarian and hedonic motivation.

Research limitations/implications
The study offers a greater understanding of customer engagement and motivational factors in the MIM environment. Future studies could consider more complex relationships with customer engagement in using MIM apps focussed on a younger generation.

Practical implications
MIM service providers should enhance customer engagement by tracking user activity and identifying customers who need to use an app more by targeting their utilitarian and hedonic needs through sophisticated marketing strategies.

Originality/value
This research enriches the understanding of key motivational factors impacting customers’ continued engagement towards using MIM, as opposed to the adoption thereof.

Authors: Fallahiarezoudar Ehsan , Ahmadipourroudposht Mohaddeseh , Ngadiman Nor Hasrul Akhmal 
Published: December 2020

Purpose
This study aims to provide an ergonomic design of the monitoring room that has resulted in safe, functional and comfortable environment for the operators, which may lead to improve the efficiency. Currently, uses of closed‐circuit televisions to monitor the critical environments are widely applicable. The information is continuously transferred and analyzed through a center called monitoring room.

Design/methodology/approach
Here, through creating a systematic analysis, a series of experiments was performed initially to evaluate and then optimize the parameters such as illumination, visual angle, operator-screen distance, number of scenes display in a single screen, workstation height, screen dimension and monitoring time that may affect the visual skill of the operators. Taguchi orthogonal array was used to analyze the significance of parameters on operator’s response time to a threat. The five parameters were distinguished as significant. Later response surface methodology was utilized to optimize the parameters.

Findings
Quadratic empirical model developed for the response time exposes the optimum response time was achievable at illumination of 500 lux, visual angle of 13°, operator-screen distance of 60 cm, three scenes, workstation height of 120 cm, screen dimension of 34” and monitoring time of 15 min. This shortened the response time by 28 per cent. The adequacy of the fitted model was successfully verified using the confirmation test with α = 95 per cent.

Originality/value
The novelty of this work lies in the application of a systematic statistical analysis, which enables considering the interaction among the noise parameters and controllable one simultaneously. Furthermore, the obtained regression model can widely be used for adjusting the parameters accordingly based on various anthropometric data.

Authors: Hendalianpour Ayad , Hamzehlou Mohammad , Feylizadeh Mohammad Reza , Xie Naiming , Shakerizadeh Mohammad Hossein 
Published: December 2020

PurposeThis study examines the potential of contracts as one of the supply chain coordination mechanisms under competitive conditions. It also investigates a two-echelon supply chain model with two manufacturers and two retailers to develop a competitive structure in grey stochastic demand.Design/methodology/approachSupply chain demand is considered as a stochastic phenomenon depending on the selling price of the product. Also, products can be replaced by market manufacturers. Each retailer faces the pricing of products from two manufacturers, leading to competition between downstream retailers. In the present study, the duopoly supply chain model was presented based on the wholesale price contract, revenue-sharing contract and quantity discount contract separately.FindingsGrey optimization and analysis of their coordination were presented. The results showed the high performance of revenue-sharing contracts in the supply chain. Thus, manufacturers will give the next priority to quantity discount contracts.Originality/valueOrdering is the main factor contributing to competitive decision-making. Meanwhile, decision-making along with ordering and pricing will be required due to the nature of the demand.
Develop a numerical approach of fuzzy logic type-2 to improve the reliability of a hydraulic automated guided vehicles
Authors: Li Zhixiong , Jamshidian Morteza , Mousavi Sayedali , Karimipour Arash , Tlili Iskander 
Published: December 2020

Purpose
In this paper, the uncertainties important components and the structure status are obtained by using the condition monitoring, expert groups and multiple membership functions by creating a fuzzy system in MATLAB software.

Design/methodology/approach
In the form of fuzzy type, the average structural safety must be followed to replace the damages or to absolutely control the decision-making. Uncertainty in the functionality of hydraulic automated guided vehicles (AGVs), without knowing the reliability of pieces, can cause failure in the manufacturing process. It can be controlled by the condition monitoring pieces done by measurement errors and ambiguous boundaries.

Findings
As a result, this monitoring could increase productivity with higher quality in delivery in flexible manufacturing systems with an increase of 70% reliability mutilation for the hydraulic AGV parts.

Originality/value
Hydraulic AGVs play a vital role in flexible manufacturing in recent years. Lately, several strategies for maintenance and repairing of hydraulic AGVs exist in the industry but are still confronted with many uncertainties. The hydraulic AGV is faced with uncertainty after 10 years of working in terms of reliability. Reconstruction of the old parts with the new parts may not have the quality and durability.

Converting debt into equity in private limited companies in Thailand
Authors: Reekie Adam 
Published: December 2020

PurposeThe purpose of this paper is to critically examine the prohibition on debt-to-equity conversions for private limited companies in Thailand, resulting from an interpretation of Section 1119 of the Thai Civil and Commercial Code (TCCC) adopted by academics and the regulator.Design/methodology/approachThis paper critically examines the interpretation of Section 1119 of the TCCC made by academics, the Thai Supreme Court and the regulator. Taking an approach, which draws on debate in the EU over the past two decades, this paper presents a new understanding of the rules relating to legal capital in Thailand. This new understanding is applied to challenge the orthodox interpretation of Section 1119.FindingsThe interpretation proposed by this paper is that debt-to-equity conversions may be permitted when viewed as shares issued in return for payment in kind. This proposed interpretation is consistent with existing Thai Supreme Court jurisprudence. In addition, a close reading of the provision, further supported by a historical investigation into the legislative drafting process, reveals that it reflects the original intention behind this provision.Originality/valueThis paper presents a view of Thai legal capital rules, which challenges the orthodox understanding of their nature, purpose and categorisation. Furthermore, the proposed interpretation of Section 1119 of the TCCC, if adopted by the regulator, would permit Thai private limited companies to engage in debt-to-equity swaps without further legislative intervention.
Policy and institutional enablers of public–private partnerships in the electricity sector in Uganda: a multi-level and path dependence perspective
Authors: Onyoin Moses , Bovis Christopher 
Published: December 2020

PurposeThis paper explains the evident disproportionality in the levels of adoption of the modality of public–private partnerships (PPPs) in Uganda by tracing the peculiar preconditions and enablers of the model's relative high adoption in the electricity sector.Design/methodology/approachKey conceptual suggestions from historical institutionalism (HI), critical juncture and path dependence are used to orient the data collection and analysis. The direct experiences and perceptions of key informants involved in policy, regulation and operations in the electricity sector are thematically analyzed.FindingsThe primacy of specific policy, institutional decisions and actions sequentially undertaken at the international, national and sectorial levels in shaping the conceivability and possibility of PPP modality is foregrounded. In particular, international advisory for the changed role of the state and the government's subsequent decision to enact and reenact specific institutional frameworks at the national and sectorial levels created important disruptions to the status quo and paved a new and relatively stable institutional path conducive for private sector participation.Research limitations/implicationsTheoretically, the paper demonstrates the ability and power of HI to support the exploration and framing of multilevel and path-dependent explanations of institutional development and policy adoption. Practically, suggestions in terms of policy, legal and regulatory enablers for the adoption of PPP are made to shape practitioners' decision-makingPractical implicationsPractically, suggestions in terms of policy, legal and regulatory enablers for the adoption of PPP are made to shape practitioners' decision-making.Originality/valueThe importance of considering factor combinations and sequences in explaining the emergence, adoption and proliferation of public policy instruments and phenomena is underscored. In addition, the discourse on PPPs is moved beyond rationalization on how to even out their adoption (and subsequently the associated benefits) across sectors.
Performance improvement of a crystallization system through optimization and sensitivity analysis
Authors: Aggarwal Anil Kr. 
Published: December 2020

PurposeThis paper deals with the performance optimization and sensitivity analysis for crystallization system of a sugar plant.Design/methodology/approachCrystallization system comprises of five subsystems, namely crystallizer, centrifugal pump and sugar grader. The Chapman–Kolmogorov differential equations are derived from the transition diagram of the crystallization system using mnemonic rule. These equations are solved to compute reliability and steady state availability by putting the appropriate combinations of failure and repair rates using normalizing and initial boundary conditions. The performance optimization is carried out by varying number of generations, population size, crossover and mutation probabilities. Finally, sensitivity analysis is performed to analyze the effect of change in failure rates of each subsystem on availability, mean time to failure (MTBF) and mean time to repair (MTTR).FindingsThe highest performance observed is 96.95% at crossover probability of 0.3 and sugar grader subsystem comes out to be the most critical and sensitive subsystem.Originality/valueThe findings of the paper highlights the optimum value of performance level at failure and repair rates for subsystems and also helps identify the most sensitive subsystem. These findings are highly beneficial for the maintenance personnel of the plant to plan the maintenance strategies accordingly.
Operational policing and child abuse: examining the impact of feminism, exploring the application of intersectionality
Authors: Romeyn Ineke , Birch Philip 
Published: December 2020

PurposeThis paper aims to examine operational policing practice and child abuse. The paper acknowledges the influence second-wave feminism has had on police practice in terms of recognising and addressing this crime type. However, child abuse is mostly considered within the context of a single incident, with those children who suffer repeat and poly-victimisation being overlooked. As a consequence, the application of intersectionality as a theoretical framework to underpin practice is considered.Design/methodology/approachThe paper adopts a case study approach. By doing so, an examination of operational policing practice with regard to child abuse takes place.FindingsFeminism, as a theoretical framework, for informing practice has its limitations, in particular with regard to operational policing practice. This is illustrated through the crime type of child abuse. With the onset of work by scholars such as Finkelhor, the importance of recognising and dealing with those who suffer from repeat and multiple forms of victimisation has become apparent. As a consequence, the policing of repeat and poly-victimisation of child sexual abuse victims needs to be enhanced. Intersectionality is considered as being a theoretical framework that can inform police practice in this area of work.Practical implicationsThe implications for practice are, namely, intersectionality has an important role to play in informing an understanding of child abuse. Intersectionality is an appropriate framework for the police to use to enhance their response to child abuse as the cornerstone of both Intersectionality and police practice is to redress unjust treatment. A targeted and consistent approach by police, education, health and community services to prevent child abuse informed by intersectionality. Building on the success of a number of police-led initiatives designed to address child abuse.Originality/valueMuch that is written about child abuse is typically done so through the lens of social work. This piece provides a timely reminder of the importance of policing in the prevention, disruption and reduction of this crime type. Further to this, the paper takes a novel approach by applying intersectionality not only as a means of understanding and addressing child abuse but as a means of informing police practice in dealing with the crime.
A heuristic approach applied to the fleet sizing problem for military ground vehicles
Authors: Longhorn Dave C. , Stobbs John Dale 
Published: December 2020

Purpose
This paper aims to propose two solution approaches to determine the number of ground transport vehicles that are required to ensure the on-time delivery of military equipment between origin and destination node pairs in some geographic region, which is an important logistics problem at the US Transportation Command.

Design/methodology/approach
The author uses a mathematical program and a traditional heuristic to provide optimal and near-optimal solutions, respectively. The author also compares the approaches for random, small-scale problems to assess the quality and computational efficiency of the heuristic solution, and also uses the heuristic to solve a notional, large-scale problem typical of real problems.

Findings
This work helps analysts identify how many ground transport vehicles are needed to meet cargo delivery requirements in any military theater of operation.

Research limitations/implications
This research assumes all problem data is deterministic, so it does not capture variations in requirements or transit times between nodes.

Practical implications
This work provides prescriptive details to military analysts and decision-makers in a timely manner. Prior to this work, insights for this type of problem were generated using time-consuming simulation taking about a week and often involving trial-and-error.

Originality/value
This research provides new methods to solve an important logistics problem. The heuristic presented in this paper was recently used to provide operational insights about ground vehicle requirements to support a geographic combatant command and to inform decisions for railcar recapitalization within the US Army.
Administrative simplification strategy with reference to the Egyptian case
Authors: Gobba Reem Mostafa 
Published: December 2020

Purpose
This paper aims to clarify the added value to governments when adopting an Administrative Simplification Strategy (ASS) to reduce administrative burdens, and its impact on both citizens and investors satisfaction. The paper highlights the difference between the traditional and strategic concepts of simplifying administrative procedures, Moreover, the paper discusses the most important steps and tools for the implementation of ASS. The paper, also, sheds light on the efforts of the Egyptian Government to simplify administrative procedures and adopt ASS.

Design/methodology/approach
This paper adopts the descriptive analytical approach to describe and analyses the basic features of the subject data from different resources includes journal articles, published papers and books, to conclude a theoretical framework of ASS. (concepts, Implementation steps, Tools, Objectives, operations and content). For the Egyptian case, the researchers uses historical perspective to analyze the efforts of the Egyptian government to simplify administrative procedures in the last decades and the content of the available ministerial decisions, presidential decrees, for example The last ministerial decisions concerning the one-stop supreme committee, were chosen as evidence of the government's interest in this matter and the analysis of the tasks entrusted to the committee to do, The decision of transfer the dependency of the ERRADA was also chosen and analyzed to indicate the extent of the government's interest in it and to what extent there is an enhancement of its role .The authors also analyzed some recent conferences and seminars and compared the administrative reform efforts with the theoretical framework of the ASS to clarify the dimensions related to ASS in Egypt.

Findings
On the theoretical level, the ASS is an umbrella term that includes various simplification projects at all the levels of governmental units. ASS leads to the improvement of governmental services provided to both citizens and investors. It is a defensive exploratory strategy that involves multiple goals and processes and requires political support, institutional framework and the comprehensive review of all related legislations, to ensure the successful implementation. Studying the Egyptian case, it is noted that the Egyptian government has not directly adopted an ASS. Yet, it has approved some stages within the framework of the adapted administrative reform plans.

Originality/value
This paper represents a framework for administrative simplification as an integrated strategy at the macro level. The strategy focuses on the overall view of the government, its integrated goals, innovation and the added value, by providing high-quality services and reducing the administrative burdens, as to improve services provided to society and ease of life, as well as to increase the level of living and citizens’ satisfaction.
