Abstract

Purpose

To identify and analyze the occurrence of Internet financial market risk, data mining technology is combined with deep learning to process and analyze. The market risk management of the Internet is to improve the management level of Internet financial risk, improve the policy of Internet financial supervision and promote the healthy development of Internet finance.

Design/methodology/approach

In this exploration, data mining technology is combined with deep learning to mine the Internet financial data, warn the potential risks in the market and provide targeted risk management measures. Therefore, in this article, to improve the application ability of data mining in dealing with Internet financial risk management, the radial basis function (RBF) neural network algorithm optimized by ant colony optimization (ACO) is proposed.

Findings

The results show that the actual error of the ACO optimized RBF neural network is 0.249, which is 0.149 different from the target error, indicating that the optimized algorithm can make the calculation results more accurate. The fitting results of the RBF neural network and ACO optimized RBF neural network for nonlinear function are compared. Compared with the performance of other algorithms, the error of ACO optimized RBF neural network is 0.249, the running time is 2.212 s, and the number of iterations is 36, which is far less than the actual results of the other two algorithms.

Originality/value

The optimized algorithm has a better spatial mapping and generalization ability and can get higher accuracy in short-term training. Therefore, the ACO optimized RBF neural network algorithm designed in this exploration has a high accuracy for the prediction of Internet financial market risk.

Abstract

In the past 10 years, the scale of running events in China has increased dramatically, and the forms of running events have also become rich and diverse. Running is not only a social phenomenon but also a historical and cultural phenomenon as an organic part of human culture with its own sociological values in China. This chapter offers insight into the development of Chinese running culture and how this has emerged from ancient and modern Chinese running cultures based on Foucault's disciplinary power theory, biopower and the technologies of the self. This chapter argues that running culture in China constructs the subjectivity of the Chinese runners under the joint action of the technologies of power and the technologies of the self. The findings acknowledge how Chinese Runners present and express themselves by showing a ‘sense of presence’. Runners illustrate the implicit or explicit meaning and value of a particular way of life through running. Runners regard running as the technology of the self for self-expression and self-creation so that individuals can control their bodies and soul, thoughts, behaviours and ways of existence. Emerging technologies of power provide possibilities for the production of running culture in China, and the current policy under the technologies of power meets the needs of runners. In Chinese running culture, power was not oppressive but productive.

Abstract

Purpose

To address the problem that the current train operation mode that train selects one of several offline pre-generated control schemes before the departure and operates following the scheme after the departure, energy-saving performance of the whole metro system cannot be guaranteed.

Design/methodology/approach

A cooperative train control framework is formulated to regulate a novel train operation mode. The classic train four-phase control strategy is improved for generating specific energy-efficient control schemes for each train. An improved brute force (BF) algorithm with a two-layer searching idea is designed to solve the optimisation model of energy-efficient train control schemes.

Findings

Case studies on the actual metro line in Guangzhou, China verify the effectiveness of the proposed train control methods compared with four-phase control strategy under different kinds of train operation scenarios and calculation parameters. The verification on the computation efficiency as well as accuracy of the proposed algorithm indicates that it meets the requirement of online optimisation.

Originality/value

Most existing studies optimised energy-efficient train timetable or train control strategies through an offline process, which has a defect in coping with the disturbance or delays effectively and promptly during real-time train operation. This paper studies an online optimisation of cooperative train control based on the rolling optimisation idea, where energy-efficient train operation can be realised once train running time is determined, thus mitigating the impact of unpredictable operation situations on the energy-saving performance of trains.

Abstract

Purpose

Past studies show that companies’ connection with the government (or politically connected companies (PCCs)) contributed negatively to their financial performance. The grabbing hand theory suggests that political connection demand companies to serve political and social obligation that exhaust companies’ financial resources. The purpose of this paper is to extend the previous studies by examining the role of monitoring mechanisms, specifically corporate governance mechanism and institutional ownership (IO), whether they weaken or strengthen the financial performance of PCCs in Malaysia.

Design/methodology/approach

The sample consists of all companies listed on the Main Board of Bursa Malaysia (previously known as Kuala Lumpur Stock Exchange) for the year of 2004-2007. The time periods were chosen because there were no significant economic and political events that could possibly distorted the financial and non-financial data.

Findings

The findings show that companies’ political connection (the presence of political figure or government representative as members of board of director) has consistently showing negative relationship with performance. The result is consistent with the grabbing hand theory that argues that companies’ connection with government would actually destroy companies’ value. The monitoring role of corporate governance as measured by the percentage of independent board members does not have any significant effect on firm’s performance. The monitoring role of corporate governance as measured by the composition of independent board members have shown a positive significant effect on the company’s performance. However the second monitoring mechanism, the percentage of institutional investors, have a tendency to weaken the company’s performance.

Originality/value

The findings of this study provide an additional understanding of the consequence of government intervention on companies’ performance. This study also highlights the role of monitoring mechanism (independence board members and IO) in strengthening or weakening the performance. The findings suggest that the proper appointment criteria for board members should be seriously considered to ensure better corporate governance structure. Therefore, the formation of the nomination committee as suggested by the current Malaysian Code of Corporate Governance play an important contribution to ensure candidates nominated as board members have proper credentials and qualifications to carry out responsibilities as board members.

Abstract

Purpose

The purpose of this paper is to examine the effect of ownership structure on the goodwill impairment policy of Malaysian listed firms. In particular, the authors test whether the direction and magnitude of goodwill impairment are related to whether firms are government or family controlled firms. Given the highly concentrated ownership of firms in Malaysia, the authors suggest that the “entrenchment effect” will take precedence over the “alignment effect”, which will be reflected in the accounting policy on goodwill valuation and impairment.

Design/methodology/approach

This study utilizes logistic and Tobit regressions to test the prediction, controlling for a range of factors that might affect the goodwill impairment decision. The data were manually collected through 579 firm-year observations from the financial reports of companies listed on the Bursa Malaysia web site for the period 2003-2009.

Findings

The authors find that family controlled firms are more likely to record goodwill impairment than non-family controlled firms. The results are, however, not significant in government-controlled firms. Similar evidence in prior studies finds that Malaysian firms are more likely to recognize and record higher goodwill impairment loss in their first year of adoption than in the subsequent years. Interestingly, in contrast to prior studies, longer chief executive officer (CEO) tenure is found to be positively associated with the likelihood to recognize and record higher impairment of goodwill.

Originality/value

This paper is one of few studies that examine the role of ownership structure on goodwill accounting policy choice where ownership structure is highly concentrated and government owned firms play a significant role in the economy. The paper also examines goodwill policy choice before, during the transition and subsequent to the adoption of the goodwill standard in Malaysia, which has not been addressed before.

Abstract

Purpose

The authors’ examination aims to offer a quantitative perspective on the interrelationships between tourist harassment, the destination image, emotions and destination revisit intent. Furthermore, it explores the moderating role of travelers' experiences and tolerance in the link between tourist harassment, the destination image and revisit intentions.

Design/methodology/approach

The authors’ examination seeks to fill this research gap by utilizing a combination of qualitative and quantitative methods to test eight hypotheses using AMOS 23 and PROCESS MARCO.

Findings

The findings showed that tourist harassment negatively impacts the destination image and revisit intentions. Moreover, it indicated that tourists' experiences and tolerance moderate the link between harassment, the destination image and revisit intentions for travelers with high levels of experience and tolerance compared to those with low levels.

Originality/value

This article contributes to travel research and service failure recovery research on tourist harassment and its consequences. To this end, it developed and validated a new tourist harassment scale. Moreover, it is the first study that examines the moderating role of visitors' experiences and tolerance on the link between tourist harassment, the destination image and revisit intentions. Finally, this article is the first to empirically offer destination harassment reduction techniques.

Abstract

Purpose

Three-dimensional (3D) casting means using additive manufacturing (AM) techniques to print the mould for casting the cast tool. The printed mould, however, should be checked for its dimensional accuracy. 3D scanning can be used for the same. The purpose of this study is to combine the different AM techniques for 3D casting with 3D scanning to produce parts with close tolerance for preparing electrical discharge machining (EDM) electrodes.

Design/methodology/approach

The four processes, namely, stereolithography, selective laser sintering, fused deposition modelling and vacuum casting, are used to print the casting mould. The mould is designed in two halves, assembled to form a complete mould. The mould is 3D scanned in two stages: before and after using it as a casting mould. The mould's average and maximum dimensional deviations are calculated using 3D-scanned results. The eutectic Sn-Bi alloy is cast in the mould. The surface roughness of the mould and the cast tool are measured.

Findings

The cast tool is selected from the four processes in terms of dimensional accuracy and surface finish. The same is electroplated with copper. The microstructure of the cast tool (low-melting-point alloy) and deposited copper is analysed using a scanning electron microscope. Energy dispersive spectroscopy and X-ray diffraction techniques are used to verify the composition of the cast and coated alloy. The electroplated tool is finally tested on the EDM setup. The material removal rate and tool wear are measured. The performance is compared with a solid copper tool. The free-form customised EDM mould is also prepared, and the profile is cast out. The same is tested on the EDM. Thus, the developed path can be successfully used for rapid tooling applications.

Originality/value

The eutectic composition of Sn-Bi is cast in the 3D-printed mould using different AM techniques combined with 3D scanning quality to check its feasibility as an EDM electrode, which is a novel work and has not been done previously.

Abstract

Purpose

To determine if the ancient Chinese tradition of Feng Shui affects residential property prices in a Western setting (“Western” and “the West” refers to the cultures and peoples of the mainlands Europe, the Americas, Australia, and New Zealand.)

Design/methodology/approach

Two approaches were adopted to measure the impact of Feng Shui design principles on property prices. First, a case study approach using a paired sales analysis was adopted to compare sales transaction prices of Feng Shui designed condominiums with sales prices of condominiums that were built without this design feature. Second, sales transaction data were analysed using multiple regression analysis in a hedonic pricing framework.

Findings

The results were mixed but provide preliminary evidence that Feng Shui impacts positively on property prices in the West.

Research limitations/implications

Firstly, the units were sold as “designer ready”. Prices for these units exclude floor coverings, painting, kitchen and bathroom fittings, appliances, counter tops and plumbing fixtures. A more precise adjustment was not able to be made as the actual build‐out cost for each unit was not available. However, it was felt that the average rate was a reasonable proxy for the cost of a build‐out. Secondly, the case study includes sales of Feng Shui designed units in only one building. A more reliable result would have been achieved had the data set included several buildings constructed using the principles of Feng Shui.

Practical implications

With the rise in popularity of the use of Feng Shui design in Western homes, understanding the effects of this on property values is important to both property valuers and investors of such property.

Originality/value

Research on the impact of cultural beliefs on residential property values in the West is limited. This paper provides a contribution to understanding the value affects of such beliefs, specifically those relating to Feng Shui.

Abstract

Purpose

Given the potential benefits of gamification in running apps, it is necessary to explore the impact of users’ gameful experience on their intention to continue using running apps. This study aims to empirically investigate this relationship along with the roles of brand attitude as a mediator and negative online reviews as a moderator.

Design/methodology/approach

The study surveyed 332 running app users in China. The reliability and validity of measures were confirmed by confirmatory factor analysis (CFA). The proposed hypotheses were verified by Process Macro.

Findings

The results show that (1) gameful experience positively impacts intention to continue using running apps, (2) brand attitude mediates the relationship between gameful experience and intention to continue using running apps and (3) negative online reviews moderate the relationship between gameful experience and brand attitude but not the relationship between brand attitude and intention to continue using running apps. Specifically, the effect of gameful experience on brand attitude decreases as users’ perception of negative online reviews increases.

Originality/value

These findings have both theoretical and practical implications for understanding the relationship among users’ gameful experience, brand attitude and intention to continue using running apps, as well as for developing effective gamification strategies to enhance user engagement and retention in running apps.

Abstract

Purpose

This exploratory study aims to determine whether a relationship is likely to exist between good feng shui and success.

Design/methodology/approach

The feng shui of eight hotel foyers and entrances were evaluated against 20 criteria, and managers asked to comment on the success of their hotels. Results were examined for possible relationships between feng shui and their descriptions of success.

Findings

Similarities between the reported success of hotel and feng shui evaluations were found in six out of the eight hotels in the study.

Research limitations/implications

Responses on success were subjective and based on five criteria, which were insufficient to determine the existence of a firm relationship between actual success and feng shui. However, this was an exploratory study, and the relationships were sufficiently strong to warrant further research.

Practical implications

Findings suggest that feng shui offers useful design principles, and hotels with good feng shui are described as being more successful than those with poor feng shui. Good feng shui appears to have a positive effect on feelings of success.

Originality/value

This is the first study that attempts to test the relationship between good feng shui and success.
