Abstract
Purpose
This study aims to clarify the influence mechanism of polishing solution type on the glazing evolution of fixed abrasive pad under different interfacial pressure conditions.
Design/methodology/approach
The tribological experiments were carried out on the friction and wear machinery with W3-5 diamond fixed abrasive pad and quartz glass workpiece under three polishing solution types of five pressure conditions. The changes of surface morphology, porosity and hardness of fixed abrasive pad were detected by white light interferometer, optical microscope and shore hardness tester.
Findings
The results showed that the glazed phenomenon of fixed abrasive pad is occurred after a certain time, which is more obvious with the increasing of interfacial pressures. The polishing solution type has a significant effect on the glazing time, although the glazed phenomenon is inevitable. The mechanism of it is that the micro-convex peaks on the surface of the fixed abrasive pad are easily wear, and the pores are blocked by the accumulation of waste debris generated during the experiment process. Thus, a smooth and high-density hard layer is formed on the surface of the fixed abrasive pad which induces the decreasing of the friction coefficient and surface roughness value. For selected polishing solution types, the wear rate of micro-convex peaks is different due to the corrosion action difference with polishing pad surface.
Originality/value
The main contribution of this work is to provide a new investigating method for further understanding the glazing evolution mechanism of fixed abrasive pad.

This paper aims to clarify the fluid infiltration mechanism at the micro-contact zone boundary of rubber-glass interfaces.
Abstract
Purpose
This paper aims to clarify the fluid infiltration mechanism at the micro-contact zone boundary of rubber-glass interfaces.
Design/methodology/approach
An in situ observation instrument was putted up; then the fluid infiltration process was recorded. Experimental results indicated that the fluid infiltration was more likely to occur in a high-contact-area-ratio zone, and the path order of fluid infiltration was first inner normal to the boundary of micro-contact area, and then along the boundary, at last external normal to the direction of boundary.
Findings
By analysis, capillary pressure is the driven force of fluid at interfaces. The micro-channel size at higher-contact-area-ratio zone is smaller, and the capillary pressure is bigger. Moreover, along different section directions of wedge-shaped region, the horizontal driving force of fluid is different due to difference of conical angle.
Originality/value
The main contribution of this study is proposing a new wedge-shaped model for better understanding the phenomena of fluid infiltration at rubber contact interfaces.

Abstract
Purpose
Hedonic value is commonly conceded as a determinant of behavioral intentions toward location-based advertising (LBA). However, the careful consideration of a mechanism behind hedonic motivation and its subsequent impact on continuance intention is inadequate. This study aims to explore the formation of hedonic value and its motivation for prolonged usage toward LBA.
Design/methodology/approach
A sample of 486 mobile users was recruited to evaluate the research model using structural equation modeling (SEM).
Findings
Results reveal that perceived utility and promotional offers are the strongest indicators of hedonic value. Moreover, social support and contextual convenience play an essential role in heightening hedonic value. Furthermore, the research lenses attempt to clarify the direct, indirect influences of hedonic value, irritation and perceived credibility on continuance intention.
Practical implications
The findings offer practitioners an understanding of how to improve hedonic value and continuance intention and develop effective LBA strategies in emerging markets.
Originality/value
This study narrows the gap of current literature by formulating a hedonic value-based continuance intention model based on uses and gratifications theory (UGT). Additionally, this work illuminates the insights into hedonic value toward LBA by identifying its motivations, including perceived utility, promotional offers, social support and contextual convenience.

Abstract
Purpose
The purpose of this paper is to examine a proposed model of location-based advertising (LBA) effectiveness upon the influence of integrative perceived values on consumers' attitude and behavioral responses in the immaturity of LBA in Vietnam.
Design/methodology/approach
A survey research method was utilized to collect data from mobile users. A real sample of 459 respondents was deemed and the Structural Equation Modeling (SEM) was applied to analyze data.
Findings
The results unveil that contextual offers, social facilitation, and advertising values have significantly positive effects on attitude; in turn, attitude mediates between these factors and purchase intention, information seeking and recommendation behaviors. Moreover, social facilitation is a significant stimulator of purchase intention. Otherwise, perceived encroached risk negatively impacts attitude.
Practical implications
Marketers should capture considerable attention to mobile natives' conscious awareness about a mechanism of tailoring their enthusiasm and behavioral responses at the embryonic stage of LBA growth in emerging countries like Vietnam.
Originality/value
This study fills the gap in the current literature by simultaneously exploring the importance of integrative perceived values to construct a hypothetical framework of consumers' responses and performance based on the uses and gratifications theory, inclusive perceived behavioral control derived from theory of planned behavior, associated with contextual value from the nature of LBA.

Abstract
Purpose
The paper aims at identifying the role of online advertising on the purchase intention (PI) of smartphones of Bangladeshi customers. The independent variable (online advertising) has been divided into five dimensional segregations: informativeness (INFO), irritation (IRR), entertainment (ENT), incentives (INC) and credibility (CRD). For increasing the value of investigation to further extent, the authors included two mediators termed as flow experience (FE) and advertising value (ADD).
Design/methodology/approach
The study has been conducted on primary data collected through a structured questionnaire received from a valid sample of 281 smartphone users selected on a random basis. SPSS (Version 24) has been used for descriptive statistical analysis, while structural equation modeling technique (utilizing AMOS 24) has been used to test the hypothetical relationships among the variables.
Findings
After a careful and bias-free statistical analysis, the results indicate that purchase intention is positively and significantly affected by all the independent components INFO, IRR, ENT, INC and CRD. Regarding the mediating effect, FE can partially mediate the relationships between IRR and PI and ENT and PI as both the direct and indirect effects are significant. On the other hand, ADD can partially mediate the relationships between IRR and PI and INC and PI, respectively, since both the direct and indirect effects are significant.
Research limitations/implications
This empirical study is expected to be beneficial for the academicians in finding some unique dimensional aspects regarding online advertising and purchase intentions.
Practical implications
The policymakers can formulate some unique online advertising policies with a view to identifying customer psychology and increase sales volume based on the findings.
Originality/value
Smartphone market in Bangladesh is growing steadily. This empirical paper has shed some lights on the unique role of online advertising on PI of smartphones of Bangladeshi customer base. Since the market scenario in Bangladesh is somewhat unique than those of Western and Eastern countries, the authors hope that the findings will add numerical theoretical and practical values for further investigation in South Asian markets.

Abstract
Purpose
Lapping is a vital flattening process to improve the quality of processed semiconductor wafers such as single-crystal sapphire wafers. This study aims to optimise the lapping process of the fixed-abrasive lapping plate of sapphire wafers with good overall performance [i.e. high material removal rate (MRR), small surface roughness (Ra) of the wafers after lapping and small lapping plate wear ratio (η)].
Design/methodology/approach
The influence of process parameters such as lapping time, abrasive size, abrasive concentration, lapping pressure and lapping speed on MRR, Ra and η of lapping-processed sapphire wafers was studied, and the results were combined with experimental data to establish a regression model. The multi-evaluation index optimisation problem was transformed into a single-index optimisation problem via an entropy method and the grey relational analysis (GRA) to comprehensively evaluate the performance of each parameter.
Findings
The results revealed that lapping time, abrasive size, abrasive concentration, lapping pressure and lapping speed had different influence degrees on MRR, Ra and η. Among these parameters, lapping time, lapping speed and abrasive size had the most significant effects on MRR, Ra and η, and the established regression equations predicted the response values of MRR, Ra and η to be 99.56%, 99.51% and 93.88% and the relative errors between the predicted and actual measured values were <12%, respectively. With increased lapping time, MRR, Ra and η gradually decreased. With increased abrasive size, MRR increased nearly linearly, whereas Ra and η initially decreased but subsequently increased. With an increase in abrasive concentration, MRR, Ra and η initially increased but subsequently decreased. With increased lapping pressure, MRR and η increased nearly linearly and continuously, whereas Ra decreased nearly linearly and continuously. With increased lapping speed, Ra initially decreased sharply but subsequently increased gradually, whereas η initially increased sharply but subsequently decreased gradually; however, the change in MRR was not significant. Comparing the optimised results obtained via the analysis of influence law, the parameters optimised via the entropy method and GRA were used to obtain sapphire wafers lapping with an MRR of 4.26 µm/min, Ra of 0.141 µm and η of 25.08, and the lapping effect was significantly improved.
Originality/value
Therefore, GRA can provide new ideas for ultra-precision processing and process optimisation of semiconductor materials such as sapphire wafers.

Abstract
Purpose
This study aims to examine the effects of in-game advertisement congruity, interactivity and intrusiveness on gamers’ attitude towards advertising and purchase intention towards advertised brands based on the stimulus-organism-response (SOR) model.
Design/methodology/approach
This study uses a structured online questionnaire to collect the data from 311 gamers aged between 18 and 35 years. This study examines mediation using bootstrapping.
Findings
This study authenticates the appropriateness of the SOR model in predicting the advertised brand purchase intentions. The results of this study indicated that attitude has a significant mediating role in the relationship of advertisement congruity, interactivity and intrusiveness with advertised brand purchase intentions. The results further revealed that this mediation was partial for all three relationships.
Practical implications
The outcomes of the study are expected to benefit researchers and scholars to identify future research directions and thereby extend current know-how on gamification in general and in-game advertising in particular. The study findings will hold significance for marketers, advertisers and media planners too. By bringing out specific allied issues connected with in-game advertising, this study will help these stakeholders to plan their marketing campaigns in an efficient manner leading to higher traction and return on investment.
Originality/value
This study provides a new perspective to comprehend the purchase intention of gamers for brands advertised in online games through mediation by applying the underpinnings of the SOR model.

Abstract
Purpose
This paper aims to test the relationships between shopping enjoyment, economic motivation, apparel shopping self-confidence, perceived informativeness, perceived irritation and buying intention, using Uses and Gratification (U&G) theory, in a mediated model using virtual dressing room (VDR) media.
Design/methodology/approach
The proposed mediation model is tested using the PROCESS (Version 3.0) macro for SPSS with bootstrapping.
Findings
Results indicate that shopping enjoyment, economic motivation and apparel shopping self-confidence have no direct relationship with buying intention. Additionally, no indirect relationship was found between apparel shopping self-confidence and buying intention. However, outcomes show that both perceived VDR informativeness and perceived VDR irritation mediate the relationships of shopping enjoyment and economic motivation with buying intention by different mechanisms when using VDR media. Additionally, the relationship between shopping enjoyment and buying intention is mediated via perceived VDR informativeness. Finally, economic motivation has both an indirect relationship with buying intention through perceived VDR irritation and a serial mediated relationship via perceived VDR irritation and informativeness.
Originality/value
This study is original in that it investigates the mediating effect of informativeness and irritation, from U&G theory, on buying intention during VDR media usage. Previous research suggests a direct relationship between shopping enjoyment, economic motivation, apparel shopping self-confidence, informativeness, irritation and buying intention. Results of this research suggest that online retailers should consider the different and complex mediating roles informativeness and irritation play in the relationship between consumer attributes and buying intention when adding media to a website.

Abstract
Purpose
Partnering has been introduced to the construction field to improve project delivery efficiency. However, little research outlines the factors influencing the intention to form partnerships. This paper aims to investigate the relationships between attitude, subjective norm perceived behavioural control (PBC) and intention to form partnering, as well as to elicit behavioural, normative and control beliefs regarding partnering formation. The study also examines the relationships between these beliefs and their respective constructs within the Theory of Planned Behavior (TPB) framework.
Design/methodology/approach
In order to achieve these objectives, a two-stage approach was employed. First, a belief elicitation study (BES) involving 20 construction industry professionals was conducted to elicit salient beliefs. Subsequently, a TPB survey was administered to 99 contractors from grades G4 to G7. Partial Least Square analysis assessed the factors influencing the intention to form partnering.
Findings
The results supported six hypotheses, while six others were unsupported. Perceived usefulness significantly influenced attitude towards intention to form partnering, followed by attitude itself, which also significantly influenced intention. The project management team and sole proprietors had significant effects on the subjective norms, while facilitating conditions and consensus on appropriation significantly affected PBC.
Practical implications
This research contributes to the existing literature by providing empirical evidence on the role of intention in partnering formation. Moreover, by applying the BES, this research extends the TPB model of intention to form partnering in construction projects, offering valuable insights for future research and practice.
Originality/value
This study investigates the relationships between attitude, subjective norm PBC and intention to form partnering, as well as to elicit behavioural, normative and control beliefs regarding partnering formation. The study also examines the relationships between these beliefs and their respective constructs within the TPB framework.

Abstract
Purpose
Robot localization technology has been widely studied for decades and a lot of remarkable approaches have been developed. However, in practice, this technology has hardly been applied to common day-to-day deployment scenarios. The purpose of this paper is to present a novel approach that focuses on improving the localization robustness in complicated environment.
Design/methodology/approach
The localization robustness is improved by dynamically switching the localization components (such as the environmental camera, the laser range finder and the depth camera). As the components are highly heterogeneous, they are developed under the robotic technology component (RTC) framework. This simplifies the developing process by increasing the potential for reusability and future expansion. To realize this switching, the localization reliability for each component is modeled, and a configuration method for dynamically selecting dependable components at run-time is presented.
Findings
The experimental results show that this approach significantly decreases robot lost situation in the complicated environment. The robustness is further enhanced through the cooperation of heterogeneous localization components.
Originality/value
A multi-component automatic switching approach for robot localization system is developed and described in this paper. The reliability of this system is proved to be a substantial improvement over single-component localization techniques.
