Abstract
Purpose
The purpose of this paper is to represent a robust image registration method to align noisy and deformed images in their Radon transform domain. Due to the limitation of imaging mechanism, the images are often highly noisy. Even worse, the objects in images have structural differences from time to time.
Design/methodology/approach
To eliminate these degressions, the proposed method is equipped with subspace-based power spectrum analysis algorithm for rotation estimation and a new global median filter least square algorithm for displacement computation.
Findings
Experiments on strongly noisy and degenerated images show that the proposed method exhibits better accuracy and robustness than phase correlation-based method. In addition, the method can also be applied to multi-modal registration, where the results are comparable to mutual information method but spending much less time.
Originality/value
A robust image registration method is proposed, which has better performance than traditional methods.

Abstract
Purpose
The purpose of this study is to introduce new tools to develop a more precise and focused bibliometric analysis on the field of digitalization in healthcare management. Furthermore, this study aims to provide an overview of the existing resources in healthcare management and education and other developing interdisciplinary fields.
Design/methodology/approach
This work uses bibliometric analysis to conduct a comprehensive review to map the use of the unified theory of acceptance and use of technology (UTAUT) and the unified theory of acceptance and use of technology 2 (UTAUT2) research models in healthcare academic studies. Bibliometric studies are considered an important tool to evaluate research studies and to gain a comprehensive view of the state of the art.
Findings
Although UTAUT dates to 2003, our bibliometric analysis reveals that only since 2016 has the model, together with UTAUT2 (2012), had relevant application in the literature. Nonetheless, studies have shown that UTAUT and UTAUT2 are particularly suitable for understanding the reasons that underlie the adoption and non-adoption choices of eHealth services. Further, this study highlights the lack of a multidisciplinary approach in the implementation of eHealth services. Equally significant is the fact that many studies have focused on the acceptance and the adoption of eHealth services by end users, whereas very few have focused on the level of acceptance of healthcare professionals.
Originality/value
To the best of the authors’ knowledge, this is the first study to conduct a bibliometric analysis of technology acceptance and adoption by using advanced tools that were conceived specifically for this purpose. In addition, the examination was not limited to a certain era and aimed to give a worldwide overview of eHealth service acceptance and adoption.

Abstract
Purpose
The purpose of this paper is to describe the Lane–Emden equation by the fractal derivative and establish its variational principle by using the semi-inverse method. The variational principle is helpful to research the structure of the solution. The approximate analytical solution of the fractal Lane–Emden equation is obtained by the variational iteration method. The example illustrates that the suggested scheme is efficient and accurate for fractal models.
Design/methodology/approach
The author establishes the variational principle for fractal Lane–Emden equation, and its approximate analytical solution is obtained by the variational iteration method.
Findings
The variational iteration method is very fascinating in solving fractal differential equation.
Originality/value
The author first proposes the variational iteration method for solving fractal differential equation. The example shows the efficiency and accuracy of the proposed method. The variational iteration method is valid for other nonlinear fractal models as well.

Abstract
Purpose
The purpose of this paper is to investigate the extent to which procedural justice influences a manager's decision‐making behaviour and the extent to which managerial values related to power‐distance moderates the relationship between participation in decision processes and procedural justice.
Design/methodology/approach
A questionnaire survey was conducted in this study. Dependent variables were the degree of participation in decision making and the degree of sharing information with subordinates. Independent variables were procedural justice and power distance.
Findings
The findings suggest that procedural justice is related positively to encouraging initiatives and information sharing. The findings also indicate that power distance moderates the relationship between procedural justice and decision‐making behaviours. Although managers were inclined to share information with employees when they believed in procedural justice, high‐power‐distance values would weaken such a positive link.
Research limitations/implications
The study explores the moderating role of power distance in the formation of perceptions about procedural justice but the interactive and distributive justice of managers are not included here for a comprehensive understanding of organizational justice. Another limitation is that the sample in the study was limited geographically to the regions of Southern China.
Practical implications
Emphasis of procedural justice among managers throughout the hierarchical system of an organization would be an effective way to improve both management effectiveness and employee performance. However, while managers develop warm relationships with their employees, they still share information reluctantly with employees in decision making when the intent is to maximize power.
Originality/value
The perspective of managers, which is adopted in this study, makes it original compared to previous studies of procedural justice. Such studies take the standpoint of employees or student subjects. Another contribution is that the cultural construct of power distance is analysed with managers at the individual level. Further, the study sheds light on important managerial issues related to the relationships between procedural justice, participation and the moderating effects of a manager's value orientation within the context of China.

Abstract
Learning outcomes
Upon completion, successful students will be able to examine the importance of digitalisation as a competitive tool in business management; use a suitable theory to justify the need for an organisation to engage in e-commerce; develop suitable strategies/solutions to challenges faced by a business organisation in the world of digitalisation of business; explain the way data analytics and digitalisation can affect business strategies and marketing functions; and identify and explain various considerations in the internationalisation of business.
Case overview/synopsis
MR.D.I.Y. “The Malaysian Sweetheart” is a case about a home improvement company that has transformed itself from a regular hardware shop into a favourite home improvement retailer in Malaysia. The case looked at the influence of e-commerce and digital transformation marks a rethinking of how an organisation uses technology, people and processes in pursuit of new business models and new revenue streams, driven by changes in customer expectations around products and services. Such transformation has indeed created opportunities and challenges for business organisation throughout the globe in their pursuit of staying competitive for MR.D.I.Y. even though they are considered the largest home improvement retailer in Malaysia. The case also introduces the students to the Uses and Gratification Theory that underpins the e-commerce business model. The management of the company is concerned about its future given the rising competition and gloomy economic conditions.
Complexity academic level
The target group for this case is undergraduate students. Specifically, it is suitable for those in the field of Entrepreneurship taking e-commerce/small business management/entrepreneurship courses. The main purpose of this case study is to assist students in critically examining how a small business evolved from a tiny neighbourhood shop to become a household name at the national level and eventually emerged as the largest home improvement company locally and abroad. Specifically, the case can be applied to topics like Retailing in Electronic Commerce, Innovative EC Systems, Social Commerce and Launching an Online Business, which all are related to the courses on E-Commerce, and this case is also suitable to any other contemporary business management module. Additionally, educators can use this teaching case as a tool in an executive programme for senior, middle and lower managers to shape their thoughts and attitudes toward managing a contemporary retailing business. With this case, it is hoped that students would be able to understand and decide wisely if they encounter similar circumstances in the future.

Abstract
The authors focus on a non-Western setting that has hardly featured in debates around political authenticity, Taiwan. The authors also adopt a novel inter-generational perspective to look at varying attitudes towards two ‘unconventional’, high-profile politicians, Ko Wen-je and Han Kuo-yu. Drawing on focus group data, the authors note the similarities and differences in the way that the different generations engage with, and assess, the two politicians with a particular focus on the extent to which their personalities, appearance, and everyday activities are perceived as authentic.

Abstract
OUR new features of record and reminiscence appear to have been appreciated by our readers; and, as this number shows, we continue with increased pages and are endeavouring to extend our scope to meet every kind of library interest. There is an atmosphere, of change and, as some think, of crisis, in library matters, especially in those of the public library. The winter to which our minds turn in mid‐September is likely to be interesting and may bring decisions of various kinds. We hope to reflect them, and, as is our invariable custom, invite readers to use us to express their views as well as their experiences.

Abstract
The smart open house provides optimal adaptability using sensing, operating, information, and communications technology, in conjunction with open building in-filled components, to perceive user needs and environmental changes, and thereby meet the needs for sustainability and a healthy living environment. These needs are particularly pressing in view of the aged society that will emerge in Taiwan after 2020. Based on the smart open house hypothesis, this study proposes using agent-based smart skins in a smart open house, where an agent-based smart skin is embedded in a lifetime home (or ageless home) with an open system construction. The agent-based smart skin operating mechanism employs fuzzy logic inference and neuro-fuzzy learning to process environmental information from sensing devices and drive skin elements, achieving adaptive action, meeting residents' lifetime use needs, and offering a user experience-oriented smart care capability.

Abstract
Purpose
The purpose of this paper is to demonstrate that the numerical method is not everything for nonlinear equations. Some properties cannot be revealed numerically; an example is used to elucidate the fact.
Design/methodology/approach
A variational principle is established for the generalized KdV – Burgers equation by the semi-inverse method, and the equation is solved analytically by the exp-function method, and some exact solutions are obtained, including blowup solutions and discontinuous solutions. The solution morphologies are studied by illustrations using different scales.
Findings
Solitary solution is the basic property of nonlinear wave equations. This paper finds some new properties of the KdV–Burgers equation, which have not been reported in open literature and cannot be effectively elucidated by numerical methods. When the solitary solution or the blowup solution is observed on a much small scale, their discontinuous property is first found.
Originality/value
The variational principle can explain the blowup and discontinuous properties of a nonlinear wave equation, and the exp-function method is a good candidate to reveal the solution properties.
