Abstract

Purpose

This study aims to design an optimized algorithm for low-cost pedestrian navigation system (PNS) to correct the heading drift and altitude error, thus achieving high-precise pedestrian location in both two-dimensional (2-D) and three-dimensional (3-D) space.

Design/methodology/approach

A novel heading correction algorithm based on smoothing filter at the terminal of zero velocity interval (ZVI) is proposed in the paper. This algorithm adopts the magnetic sensor to calculate all the heading angles in the ZVI and then applies a smoothing filter to obtain the optimal heading angle. Furthermore, heading correction is executed at the terminal moment of ZVI. Meanwhile, an altitude correction algorithm based on step height constraint is proposed to suppress the altitude channel divergence of strapdown inertial navigation system by using the step height as the measurement of the Kalman filter.

Findings

The verification experiments were carried out in 2-D and 3-D space to evaluate the performance of the proposed pedestrian navigation algorithm. The results show that the heading drift and altitude error were well corrected. Meanwhile, the path calculated by the novel algorithm has a higher match degree with the reference trajectory, and the positioning errors of the 2-D and 3-D trajectories are both less than 0.5 per cent.

Originality/value

Besides zero velocity update, another two problems, namely, heading drift and altitude error in the PNS, are solved, which ensures the high positioning precision of pedestrian in indoor and outdoor environments.

This study aims to focus on the optimized design and mechanical properties of gradient triply periodic minimal surface cellular structures manufactured by selective laser melting.

Abstract

Purpose

This study aims to focus on the optimized design and mechanical properties of gradient triply periodic minimal surface cellular structures manufactured by selective laser melting.

Design/methodology/approach

Uniform and gradient IWP and primitive cellular structures have been designed by the optimized function in MATLAB, and selective laser melting technology was applied to manufacture these cellular structures. Finite element analysis was applied to optimize the pinch-off problem, and compressive tests were carried out for the evaluation of mechanical properties of gradient cellular structures.

Findings

Finite element analysis shows that the elastic modulus of IWP increased as design parameter b increased, and then decreased when parameter b is higher than 5.5. The highest elastic modulus of primitive increased by 89.2% when parameter b is 6. The compressive behavior of gradient IWP and primitive shows a layer-by-layer way, and elastic modulus and first maximum compressive strength of gradient primitive are higher than that of gradient IWP. The effective energy absorption of gradient cellular structures increased as the average porosity decreased, and the effective energy absorption of gradient primitive is about twice than that of gradient IWP.

Originality/value

This paper presents an optimized design method for the pinch-off problem of gradient triply periodic minimal surface cellular structures.

Abstract

Purpose

This study aims to explore the combined strategies leading to successful repair of two types of trust in Chinese construction projects and provide an effective guidance and control trust repair in construction projects. During the research period, the author interviewed 150 managers from 50 Chinese construction projects and collected details of 125 violations. The research examines the effect of combined strategy of trust repair in Chinese management scenario.

Design/methodology/approach

This study adopted a mixed, quantitative, qualitative and exploratory approach. The author first extracted six strategies, namely, apology, denial, penance, communication, promise and compensation, from the literature review and generalization. Then, the author conducted an interview with 150 managers from 50 China construction projects. And the author analyzed the data through qualitative comparative analysis (QCA).

Findings

When competence-based trust is broken, violators should adopt communication and promise, demonstrate their competence and qualification, and change the attributions of competence from the trustor. When integrity-based trust is broken, violators should apologize, actively admit the mistake, show a positive attitude and seek the forgiveness from the trustor. After reconstructing trustors' perceptions of competence or integrity, violators should also make a promise to trustors for the future. The result of this research not only illustrates the sufficiency and necessity of a single strategy for trust repair but also explores the combination of trust repair strategies that rebuild the trust.

Research limitations/implications

This study is limited to 50 construction projects in the Chinese construction context, so conclusions are limited in application. Data used in this research did not provide an in-depth analysis of trust repair failures. Thus, additional research is needed to explore why trust was not repaired. The study is also limited to examining the Chinese construction project organizations only, and future studies should incorporate organizations in other nations and regions.

Practical implications

Compared with using a single strategy, a combined strategy provides a contribution to the future practice of repair broken relationship between construction project organizations. This research helps to organize decisions and benefits managers, from Chinese owners and contractors, in choosing which of these strategies repair trust. The author also provides a specific combination of strategies to repair relationships for international companies that have conflicts with Chinese construction companies.

Originality/value

This research is among the early studies in China that preliminary examines the combined strategy of trust repair between Chinese owners and contractors by using causal attribution theory and QCA. This study makes a valuable contribution toward combined strategy in construction project and the knowledge system of trust repair. Future studies could build on the findings from the current study to develop a cross-cultural research on trust repair.

Abstract

Purpose

Although user behaviors in social network service (SNS) have been well studied in prior literature, most of these studies focus on those behaviors with relatively deep user engagement such as information disclosure, while the underlying mechanisms that explain users’ shallow engagement behaviors (e.g. Like behavior) have been rarely discussed. To fill this research gap, the purpose of this paper is to propose and empirically test a research model to identify the antecedents of Like behavior.

Design/methodology/approach

This study identifies the distinctions between post behavior and Like behavior and develops a research model of Like behavior by emphasizing the role of sense of presence from the perspective of symbolic interactionism. The model is tested through a survey with 479 users of WeChat (a popular SNS tool in China). Structural equation modeling, SmartPLS in particular, is used for data analysis.

Findings

Three value perceptions, namely cognitive value, hedonic value and social value, are found to be positively associated with Like intention, and sense of presence is found to affect Like intention both directly and indirectly via the three value perceptions.

Research limitations/implications

The research model is tested based on a specific SNS in China, so whether the conclusions can be applied to other research contexts should be further examined in future research. This study identifies the distinctions between post behavior and Like behavior and suggests to view the Like behavior from the perspective of symbolic interactionism.

Practical implications

The paper outlines ways to effectively promote SNS users’ Like behaviors by enhancing the functions related to three value perceptions, especially by enriching the ways that facilitate interpersonal interactions.

Originality/value

This paper is one of the first to distinguish Like behavior from post behavior in SNS, propose and empirically test a research model of Like behavior. In particular, this paper strengthens the important role of sense of presence from the perspective of symbolic interactionism which has rarely been investigated in prior studies.

This study aims to examine the effects of system and information characteristics in developing users' perceptions towards ubiquitous decision support systems (UDSS).

Abstract

Purpose

This study aims to examine the effects of system and information characteristics in developing users' perceptions towards ubiquitous decision support systems (UDSS).

Design/methodology/approach

The research model is empirically examined with survey data from 218 mobile users who have adopted a UDSS, i.e. mobile Dianping.com. A structural equation modelling approach is employed to assess the hypotheses.

Findings

The findings demonstrate that system characteristics of wireless networks, mobile devices and mobile applications significantly predicted system quality, which in turn determined system usefulness. Localisation, immediacy and customisation of mobile word‐of‐mouth were the major predictors of information quality, which in turn determined information usefulness.

Originality/value

This study contributes to our current understanding of ubiquitous commerce, especially mobile word‐of‐mouth, by presenting an integrated research framework, identifying system and information characteristics that are specific to the ubiquitous era, extending system quality and system usefulness from a single system to a combination of systems, and empirically examining the crossover effects between system and information factors.

Abstract

Purpose

This study aims to examine the underlying mechanism of buyer–seller ties and salespeople’s performance. Also examined was the moderating effects of the density of the customer network in which the salesperson is embedded.

Design/methodology/approach

The study developed a framework incorporating five key variables: strength of ties, network benefits, network density, sales effectiveness and sales revenue. The framework was tested using data from insurance companies in China.

Findings

Process regression and stepwise regression results indicated that information, influence and solidarity benefit will mediate the effects of strength of ties on sales effectiveness both when taken as a set and separately. Information, influence and solidarity benefit will mediate the effects of strength of ties on sales revenue when taken as a set, but only influence will mediate the effect separately. In addition, the positive relationship between strength of ties and solidarity benefit is weaker when network density is high.

Practical implications

Sales managers should initiate trainings and workshops about how to obtain high-quality information from customers, improving influencing power and establishing solidarity with customers. Moreover, salespeople should avoid conducting business with a group of customers if they are densely connected to one another.

Originality/value

On the one hand, this study contributes to the underlying mechanism research on buyer–seller ties and sales performance. On the other hand, it contributes to the contingency research on sales performance and the development of social network theory.

Abstract

Purpose

The purpose of this paper is to investigate the mediating role of psychological empowerment in the relationship between ethical leadership and employee work engagement as well as the moderating effect of power distance orientation.

Design/methodology/approach

With a multi-wave survey, this paper uses a sample of 251 employees from the banking sector in Pakistan to test the hypotheses.

Findings

The results reveal that psychological empowerment partially mediates the relationship between ethical leadership and employee work engagement. Besides, power distance orientation mitigates the positive relationship between ethical leadership and psychological empowerment as well as the indirect effect of ethical leadership on employee work engagement via psychological empowerment.

Originality/value

This study contributes to the existing ethical leadership literature by identifying psychological empowerment as an additional mediator and power distance orientation as a boundary condition, in the relationship between ethical leadership and employee work engagement.

Abstract

Purpose

The purpose of this paper is to mainly focus on the relationship between the scanning strategy and surface quality. Surface quality, including surface roughness and flatness, is important for printed parts. So this paper optimizes the surface quality by changing the scanning strategy.

Design/methodology/approach

This paper is based on the phenomenon after the printed parts. A clear trend can be seen that the surface roughness on the side face shows a clear zigzag shape, so an optimized scanning strategy is used. Surface roughness in measured in macrostructure first by Mitutoyo and the flatness is measured by Hexagon Metrocogy. After that, microstructure on the side face is seen by RTEC to explain this phenomenon.

Findings

The surface quality on the side face shows a significant optimize by changing the scanning strategy. The surface quality on the positive face has some optimization to some degree.

Originality/value

This paper determines the relationship between the surface roughness on the side face and the scanning strategy. Few studies focus on the surface roughness, especially on the side face. Some studies try to optimize the surface roughness on the positive face. However, researchers always neglect the surface roughness on the side face. 2. This paper measures not only the surface roughness, but also the flatness. Surface roughness has a significant impact on the surface quality. However, it still has some limitations. Flatness is also measured to make this paper more representative. 3. This paper explains why scanning strategy can affect the surface quality. These images explain the research better and not just at the theoretical level.
