Abstract

Purpose

Simulation techniques for cost management are useful for modeling uncertainties, making decisions, and improving the accuracy of cost estimation. Despite their usefulness, the application of these techniques in construction projects seems to be uncommon in the construction sector in Malaysia. The purpose of this paper is to determine the application of simulation techniques for cost estimation and control and to assess their influence on project cost performance.

Design/methodology/approach

A survey questionnaire was used to collect data from 83 government agencies, consultant firms, and contractor firms in Kuala Lumpur, Malaysia.

Findings

The findings revealed that knowledge of respondents and usage of cost simulation techniques in the Malaysian construction industry is low. In addition, main barriers of implementing cost simulation techniques are identified. Cost performance of construction projects in Malaysia is satisfactory; however, there is no association between this performance and the application of simulation techniques.

Originality/value

This paper contributes to construction management field by highlighting the main simulation techniques for cost management and drawing the attention of construction professionals and contractors to implement these techniques in construction projects.

Abstract

Purpose

Three-dimensional (3D) food printing is an innovative technology used to customize food products through the integration of digital technology and food ingredients. The purpose of this study is to assess the current state of research in the field of 3D food printing, identify trending topics and identify promising future research directions.

Design/methodology/approach

This bibliometric review systematically evaluates the field of 3D food printing using data from published literature in the Web of Science database. After reference screening, 812 articles were included in the analysis.

Findings

The result reveals that research in 3D food printing primarily focuses on the optimization and characterization of mechanical and rheological properties of food inks and that post-printing processing, such as laser treatment, has emerged recently as an important consideration in 3D food printing. However, extant works lack animal and human studies that demonstrate the functionality of 3D-printed food.

Originality/value

This sophisticated bibliometric analysis uncovered the most studied current research topics and the leading figures in the area of 3D food printing, providing promising future research directions.

Abstract

Purpose

This paper aims to present a new design for removable partial dentures (RPDs) for partially edentulous patients to improve the efficiency and quality of RPD manufacturing. Additive and subtractive manufacturing technologies and zirconium silicate micro-ceramic bonding in the aesthetic zone are used herein.

Design/methodology/approach

A case was presented. First, RPD digital definitive casts were acquired, and then digital frameworks with crown retainers and digital crowns were obtained by computer-aided design (CAD). The titanium alloy frameworks and resin crowns were fabricated by three-dimensional (3D) printing and computer-aided manufacturing (CAM) processes, respectively. The crowns adhered to the crown retainers. Ceramage bonding was used to reform the gingival anatomy in the aesthetic zone during the fabrication of the RPDs. The finished RPDs were assessed by a clinician and delivered to the patient.

Findings

The RPDs were conventionally assessed by a clinician, were deemed to be accurate and satisfied both the patient and clinician.

Originality/value

This novel method provides a way to fabricate RPDs with a combination of additive and subtractive manufacturing technologies. The design of the framework was different from that of a conventional framework because it contained the crown retainers, and the traditional base retainer no longer existed. Ceramage bonding was used to replicate the gingival anatomy in the aesthetic zone. The new RPDs provided accuracy and were less time-consuming to produce than those produced with the traditional method. The new method enables the digital manufacturing of nearly the entire RPDs.

Abstract

Purpose

The internet creates ample opportunities to start a mobile social commerce business. The literature confirms the issue of customer trust for social commerce businesses is a challenge that must be addressed. Hence, this study aims to examine the antecedents of trust in mobile social commerce by applying linear and non-linear relationships based on partial least squares structural equation modeling and artificial neural network model.

Design/methodology/approach

This study applied a non-linear artificial neural network approach to provide a further understanding of the determinants of trust in mobile social commerce based on a non-linear and non-compensatory model. Besides, a questionnaire was distributed to 340 social commerce customers in Malaysia.

Findings

The conceptual framework for investigating trust in mobile social commerce has various advantages and contributions to predicting consumer behavior. The results of the study showed there is a positive and significant relationship between social support, presence and unified theory of acceptance and use of technology2 (UTAUT2). In addition, UTAUT2 has fully mediated the relationship between social support, presence and trust in social commerce. Finally, the results concluded the relationship between UTAUT2 and trust in social commerce would be stronger when the diffusion of innovation and innovation resistance is high and low, respectively.

Research limitations/implications

The current study provides a novel perspective on how customers can trust social m-commerce to provide real solutions to managers of encouraging e-marketing among consumers.

Practical implications

This paper shows how businesses can develop trust in social m-commerce in Malaysian markets. The findings of this study probably could be extended to other businesses in Asia or other countries. Because trust in social e-commerce has a dynamic role in consumer behavior and intention to purchase.

Originality/value

This study provided a new perspective on mobile social commerce and paid more attention to an investigation of such emerging commerce. The originality of this study is embodied by investigating an integrated model that included different theories that presented new directions of trust in mobile social commerce through social and behavioral determinants.

Abstract

Purpose

The purpose of this paper is to examine the essential abilities service employees need to deliver an exceptional service that delights customers and to identify effective methods to train exceptional service employees.

Design/methodology/approach

The authors conducted in-depth interviews with seven senior butlers and three human resource managers from four of the most renowned five-star hotels in Taiwan. Interviews with the two groups of participants provided good triangulation and allowed us to gain different perspectives and to obtain a more holistic understanding of the research topic.

Findings

This study systematically organized the essential abilities required to deliver delightful service into three hierarchical levels: professionalism, the ability to respond to customers’ emotions and hidden needs and build bonds with them, and the ability to deliver one-stop service. The authors propose that the most effective training method is to develop a customer-oriented service climate. Such an environment will enable service employees to be naturally molded into exceptional service personnel. Several training methods are identified to build a customer-oriented service environment within a company.

Research limitations/implications

This study focused on the staff of five-star hotels. The proposed service standards and abilities may only be applicable to high-end service providers. Furthermore, this study used only a qualitative research method (in-depth interviews) to develop a preliminary training model to foster outstanding service employees. This model can be further verified using a quantitative method and a larger number of participants in a future study.

Originality/value

This research provides contributions to the literature on delightful service and human resources management.

Abstract

Purpose

The purpose of this study is to process the wettability surface of the ZrO2 ceramics to improve their surface friction performance.

Design/methodology/approach

Microtexture was processed on the surface of ZrO2 ceramics using a femtosecond laser. The three-dimensional texture morphology, surface contact angle, friction curve and wear morphology were measured by the laser confocal microscope, the contact angle meter, the reciprocating friction and wear tester and the scanning electron microscope, respectively. Based on Wenzel and partial impalement models, a geometric model of micro pits is established to study the influence mechanism of micro pit depth, diameter and distribution density on wettability and to analyze the relationship between surface wettability and tribological properties.

Findings

The results show that changing the geometric characteristics of the texture will lead to a change in the solid-liquid contact mode, and then lead to a change of in the surface contact angle. Wettability is an essential factor that affects the reduction of surface friction. The construction of a reasonable texture can enhance the surface hydrophilicity, which is conducive to the formation of a lubricating film on the ceramic surface, thereby reducing abrasive and adhesive wear, and improving the wear resistance of the ZrO2 ceramic surface.

Originality/value

The results provide a theoretical reference for femtosecond laser surface texture wettability regulation and tribological performance improvement.

Abstract

Purpose

The purpose of this paper is to analyse the effect of positive online consumer reviews (OCRs) on changes in the individual’s evaluations from the pre-purchase to the post-consumption stage, studying satisfaction, attitude towards the firm and purchase intention. The effect of positive OCRs may differ depending on whether the product performance is high or low, i.e., whether the product meets the objectives of the consumer. So, the paper also explores different effects that positive OCRs can have on changes in the individual’s evaluations depending on the kind of performance.

Design/methodology/approach

Two studies based on the experimental methodology are carried out and several statistical techniques are applied: confirmatory factorial analysis, mixed between-within subjects analysis of variance and post-hoc analysis.

Findings

Results demonstrate that the effect of positive OCRs continues after consumption. Depending on the performance, this effect can be positive (negative) and verify (contrast with) the individual’s pre-purchase evaluations. Moreover, this effect is always more intense when the performance is low.

Originality/value

It explores the changes in the individual’s evaluations about the product and the firm, going beyond the immediate effect of positive OCRs. It also explains the effects of positive OCRs for high and low performance. Finally, it demonstrates that OCR effects are not symmetrical for high and low performance.

Abstract

Building on a proposed four-phase model of the design revolution, I outline an expanded domain to which design ideas may be applied, and offer a design theory that has general application to the expanded design domain. Numerous disciplines within the domain of design, which have been separately developed, are converging through digital devices and software such as computer-aided design programs. I refer to this “Connection” as the first phase of the design revolution. In the second “Expansion” phase of the design revolution, I expect that the domain where principles of design are applied will be expanded beyond the visual to include all five human senses. The design theory that I propose is a logical application of design principles to various disciplines in the second phase of the revolution. In the third “Application” phase of the design revolution, the design theory will be applied not only to conventional objects of design such as products and services, but also to institutions and systems such as governments, firms, and households. Finally, in the fourth “Integration” phase of the revolution, various parts of the world will be integrated into a holistic system under a single design theory.
