Semantic stereo visual SLAM toward outdoor dynamic environments based on ORB-SLAM2
Authors: Li Yawen , Song Guangming , Hao Shuang , Mao Juzheng , Song Aiguo 
Published: January 2023

Purpose
The prerequisite for most traditional visual simultaneous localization and mapping (V-SLAM) algorithms is that most objects in the environment should be static or in low-speed locomotion. These algorithms rely on geometric information of the environment and restrict the application scenarios with dynamic objects. Semantic segmentation can be used to extract deep features from images to identify dynamic objects in the real world. Therefore, V-SLAM fused with semantic information can reduce the influence from dynamic objects and achieve higher accuracy. This paper aims to present a new semantic stereo V-SLAM method toward outdoor dynamic environments for more accurate pose estimation.

Design/methodology/approach
First, the Deeplabv3+ semantic segmentation model is adopted to recognize semantic information about dynamic objects in the outdoor scenes. Second, an approach that combines prior knowledge to determine the dynamic hierarchy of moveable objects is proposed, which depends on the pixel movement between frames. Finally, a semantic stereo V-SLAM based on ORB-SLAM2 to calculate accurate trajectory in dynamic environments is presented, which selects corresponding feature points on static regions and eliminates useless feature points on dynamic regions.

Findings
The proposed method is successfully verified on the public data set KITTI and ZED2 self-collected data set in the real world. The proposed V-SLAM system can extract the semantic information and track feature points steadily in dynamic environments. Absolute pose error and relative pose error are used to evaluate the feasibility of the proposed method. Experimental results show significant improvements in root mean square error and standard deviation error on both the KITTI data set and an unmanned aerial vehicle. That indicates this method can be effectively applied to outdoor environments.

Originality/value
The main contribution of this study is that a new semantic stereo V-SLAM method is proposed with greater robustness and stability, which reduces the impact of moving objects in dynamic scenes.

Published: January 2023

Purpose
Construction cost management is one of the important processes that should be achieved effectively and accurately for successful project delivery. Modern-day construction cost management demands a high level of spatial skills. Augmented reality (AR) can potentially increase the stakeholders’ spatial skills as a supportive technology to traditional cost management tools and techniques. AR is a breakthrough technology that could considerably ease execution in various industries, but AR applicability in cost management has not been studied extensively. Thus, this study aims to explore the use of AR in construction cost management tools and techniques.

Design/methodology/approach
Data were collected using a qualitative approach consisting of two rounds of the Delphi technique. A total of 22 experts in the construction and information technology fields were interviewed using a purposive sampling technique. The manual content analysis helped analyse data.

Findings
The study identified AR features with the potential to increase the usage of cost management tools and techniques. AR can enable spatial skills (abilities, thinking and tasks) in most cost management tools and techniques. However, technical, cultural and technical and cultural barriers obstruct the use of AR in the construction industry.

Originality/value
The usage of AR in construction cost management tools and techniques has not been examined in detail until now. Thus, the study was developed to meet the industry needs and fill the literature gap to investigate the potential use of AR in construction cost management tools and techniques.
The relation between auditing and accounting timeliness in Swedish private firms
Authors: Hartwig Fredrik , Hansson Emil , Nielsen Linn , Sörqvist Patrik 
Published: January 2023

Purpose
The purpose of this study is to examine the relationship between auditing/non-auditing and accounting timeliness among Swedish private firms.

Design/methodology/approach
This paper uses regression analysis to test the relationship between auditing and two measurements of timeliness; lead time and late filing. The sample consists of Swedish private firms.

Findings
This paper finds that audited firms, when compared with unaudited firms, are significantly less timely. Moreover, greater profitability was associated with more timeliness but only for audited firms. The results of this paper also show that firms being audited by a big 4 auditor are significantly timelier than firms being audited by a non-big 4 auditor.

Practical implications
The findings in this paper suggests that one aspect of accounting quality, timeliness, does not seem to benefit from auditing in a Swedish context. There is a debate about whether the threshold levels in Sweden should be raised so that more firms voluntarily can opt out of audit. Those opposing a raised threshold level claim that auditing has positive effects on accounting quality and consequently that a raised level would have adverse effects. The findings in this paper do not support such a claim.

Originality/value
Little is known about timeliness in private firms compared to public firms and this paper fills that void. Contrary to prior research, findings show that unaudited firms in a Swedish regulatory setting actually are timelier than their audited counterparts. This questions one of the (presumed) benefits of auditing and should stimulate more research on this issue.
The role of the feedback environment in expatriate adjustment
Authors: Armon Brigitte , Steelman Lisa , Jensen Sarah 
Published: January 2023

PurposeThe purpose of the present study is to examine the role of the feedback environment in expatriate adjustment and subsequent performance. Based on newcomer adaptation and sensemaking theories, the authors proposed that the supervisor and coworker feedback environments would serve as informational resources, reducing the ambiguity associated with the expatriate's new setting.Design/methodology/approachThis study was conducted with a broad sample of assigned expatriates (N = 95) originating from 33 different countries and currently working in 35 different host countries. Mediation analysis using a bootstrapping methodology was conducted to test the hypotheses.FindingsThe authors found that the supervisor feedback environment and coworker feedback environment were both related to expatriate adjustment through role clarity. The authors also found that the supervisor feedback environment was indirectly related to expatriate job performance and intent to leave the international assignment through both role clarity and adjustment.Originality/valueThis study examines the extent to which the supervisor and coworker feedback environments enable expatriates on an international assignment. Expatriates face challenges that may be ameliorated by constructive feedback practices. The authors discuss how organizations can improve expatriate sensemaking and adjustment through improved feedback practices.
The role of badges to spur frequent travelers to write online reviews
Authors: Moro Sérgio , Stellacci Stefania 
Published: January 2023

Purpose
Online travel reviews platforms have become innovative information systems due to the incorporation of sophisticated gamification elements such as visually appealing badges. This study aims to analyze three features of the review after leveling up a badge: review length (number of words), sentiment scoring and period between two successive reviews (number of days until the next review is written).

Design/methodology/approach
A total of 77,000 online TripAdvisor reviews written by 100 frequent travelers and contributors are analyzed using a data mining approach. A data-based sensitivity analysis is then conducted to provide an understanding of the data mining trained models.

Findings
The results show evidence that badges appealing for self-pride (“badge passport”) and for peer-recognition (“badge helpful”) have significant influence across the lifespan of online review, whereas badges simply awarded by counting the contributions have little effect.

Originality/value
To the best of the authors’ knowledge, this study provides the first analysis of how an experienced traveler is influenced as the badges and points are being awarded. Intrinsic motivational factor to award badges for standard contributions scarcely influence user behavior. Badges need to be designed to reward accomplishments that are not so trivial to be achieved and that do not depend entirely on the user.
Understanding Vietnamese consumers’ perception and word-of-mouth intentions towards Airbnb
Authors: Do Thuc Thi Mai Doan , Pereira Luis Nobre 
Published: January 2023

Purpose
This paper aims to provide a comprehensive understanding of Vietnamese consumers’ perceived value and to explore the relationships between its constructs, satisfaction and (e)word-of-mouth (WOM) intentions towards Airbnb. Moreover, the relationship between traditional WOM and electronic WOM (eWOM) was also investigated.

Design/methodology/approach
An electronic survey was applied to collect data on a sample of Vietnamese Airbnb guests. A total of 352 questionnaires were collected, from which 163 eligible Airbnb users remained for data analysis. The partial least square approach to structural equation modelling was used to analyse the data.

Findings
The findings suggested that monetary, functional and hedonic benefits significantly impact Vietnamese customer satisfaction (CS) with Airbnb accommodation, which, in turn, acts as a direct effect and mediator in encouraging customers’ (e)WOM-giving intentions. Moreover, traditional WOM intention positively influences eWOM giving intention.

Originality/value
This study provides a better comprehension of customers’ perceived value that influences CS and their (e)WOM intentions towards Airbnb. Secondly, it extends the literature on WOM intentions from the message communicator’s perspective by confirming the positive association between traditional and eWOM-giving intentions. Finally, this paper reveals insights into the sharing accommodation in a fast-growing market in South East Asia (Vietnam), which supports sharing accommodation platforms and service providers to develop appropriate marketing strategies.

Purpose
This study aims to analyse the mechanism of trust instrument from a Shariah point of view. Analysis of the mechanism would determine the extent to which its implementation can resolve estate planning issues such as frozen estate and the issue of naming beneficiaries under the age of 18.

Design/methodology/approach
This is a qualitative study method through library research. To explore the mechanism of trust instrument, an in-depth interview with five participants using purposive sampling and analyses of documents were used. The selection of this sample allows the researcher to obtain specific data in their field of expertise. Therefore, two officers from the Trust Administration Department of Amanah Raya Berhad (ARB) and three Shariah advisors from ARB (MPS ARB) were interviewed to find out the mechanism of trust instrument from the Shariah perspective. The researcher also referred to the trust deed documents, ARB company policies, field case studies such nomination cases and trust accounts, articles and court cases.

Findings
The trust instrument meets Shariah requirements even though it is based entirely on the Civil Law. The comprehensive and flexible features of trust deeds can help donors to plan systematically during their lifetime.

Research limitations/implications
This study only focuses on the trust instruments that are currently being implemented in the ARB. Five trust products were analysed to achieve the objectives of the study, namely, the Normal Trust, Safecare and Safecare Premium, Takaful Care, Hibah (literally “gift”) as well as Trust and Declaration of Hibah.

Practical implications
The implementation of trust instrument at an early stage can ensure the property is well managed through a trust deed, guarantee the life of the beloved heirs after the death of the donor and prevent the property from being frozen.

Originality/value
This study comprehensively describes the trust instrument from the Shariah perspective and its implementation mechanism in the industry.

Influence of target industry growth on premiums in cross-border acquisitions
Authors: Bebenroth Ralf , Ahmed Kashif 
Published: January 2023

PurposeIn this paper, the knowledge-based view of the firm is applied to theoretically elucidate and empirically examine the influence of target industry growth on premium payments in cross-border acquisitions. This study aims to extend internally driven Mergers and Acquisitions research efforts of acquirers to industry contingencies of targets by analyzing cross-border acquirers located within the group of seven (G7) countries.Design/methodology/approachThis study’s investigation covers 209 cross-border acquisitions from 2012 to 2019 undertaken by firms located within the G7 countries. This paper used generalized estimation equations method to test the hypotheses applying Gaussian distribution for the dependent variable, an identity link function, exchangeable correlation structure and robust standard errors.FindingsThis study’s results reveal that target industry growth determines premiums. Furthermore, this study shows that acquirer industry growth, as well as acquirer slack, moderates this relationship. This study is built on the notion that industry contingencies influence premiums even when target firms are based in foreign countries.Originality/valueTo the best of the authors’ knowledge, unlike other studies, this is the first to explicitly focus on premiums for multiple cross-border acquisitions by hand selecting nine years of industry sale figures for 53 industries separately in each of the G7 nation countries (leading to 371 separate downloads of data samples). This study contends that industry growth of cross-border targets matters for premium payments.
An investigation of sustainable consumption behavior: the influence of environmental concern and trust in sustainable producers on consumer xenocentrism
Authors: Ghaffar Abdul , Zaheer Zaidi Syed Shahid , Islam Tahir 
Published: January 2023

PurposeUnsustainable spending patterns of consumers directly contribute to 30–40% of environmental degradation, mainly in waste. Packaging is a vital part of responding to the main challenges of sustainable food consumption on the global stage. This study aims to investigate how environmental concern and trust in sustainable producers impact the sustainable consumption behaviors of consumers via the mediation of consumer xenocentrism and the moderation of eco-label and country of origin (COO) of buying sustainable packaged foreign food brands.Design/methodology/approachThis study employed a quantitative method. The authors used Smart PLS 3.0 structural equation modeling (SEM) technique for data analysis. Data from the participants were collected through the convenience sampling technique. A total of 343 valid responses were received.FindingsThe results indicate that xenocentrism is an emerging behavior among Pakistani consumers. The authors found that a high degree of environmental concern and trust in sustainable producers are the antecedents of consumer xenocentrism, which leads to sustainable consumption behavior.Research limitations/implicationsThis research highlights the importance of customers’ xenocentric attitudes that lead to sustainable consumption behavior. The research findings provide vital information for researchers, policymakers, academics, practitioners, industry professionals, brand managers and top management, especially in designing the environmental sustainability framework. Although the findings support theory of planned behavior (TPB), future studies can contrast different theories’ contributions to sustainable consumption behavior improvement. Also future researchers may analyze the impact of culture on the association between sustainable consumption and consumer attitudes toward environmental concerns and trust in sustainable producers.Originality/valueThis research contributes to practice and theory, as consumer xenocentrism is a relatively unexplored area of research in developing countries. To the best of the authors' knowledge, this study is the first to examine consumers’ xenocentric attitudes to sustainable consumption empirically.
A monopole polarisation diversity antenna for high density packaging MIMO applications
Authors: K.M. Dhanalakshmi , G. Kavya , S. Rajkumar 
Published: January 2023

Purpose
This paper aims to propose a single element, dual feed, polarisation diversity antenna. The proposed antenna operates from 2.9 to 10.6 GHz for covering the entire ultra-wideband (UWB) frequency range. The antenna is designed for usage in massive multiple input multiple output (MIMO) and closed packaging applications.

Design/methodology/approach
The size of the antenna is 24 × 24 × 1.6 mm3. The radiating element of the antenna is derived from the Sierpinski–Knopp (SK) fractal geometry for miniaturization of the antenna size. The antenna has a single reflecting stub placed between the two orthogonal feeds, to improve isolation.

Findings
The proposed antenna system exhibits S11 < −10 dB, S21 < −15 dB and stable radiation characteristics in the entire operating region. It also offers an envelope correlation coefficient < 0.01, a diversity gain > 9.9 dB and a capacity loss < 0.4 bps/Hz. The simulated and measured outputs were compared and results were found to be in similarity.

Originality/value
The proposed UWB-MIMO antenna has significant size reduction through usage of SK fractal geometry for radiating element. The antenna uses a single radiating element with dual feed. The stub is between the antenna elements which provide a compact and miniaturized MIMO solution for high density packaging applications. The UWB-MIMO antenna provides an isolation better than −20 dB in the entire UWB operating band.

Published: January 2023

PurposeIn this work, the effect of porosity volume fraction, porosity types, material grading index, variable disk profiles and aspect ratio on disk performance was studied by performing limit elastic speed analysis of functionally graded porous rotating disks (PFGM) under thermo-mechanical loading.Design/methodology/approachThe composition change was varied by employing the power law function. The thermo-mechanical properties of PFGM such as Young's modulus and yield strength were estimated using modified rule of mixture, for density and coefficient of thermal expansion rule of mixture was used. The even and uneven distribution of porosity in a disk was taken as uniform, symmetrical, inner maximum and outer maximum. The problem was then solved with the help of the variational principle and Galerkin's error minimization theory.FindingsThe research reveals that the grading parameter, disk geometry and porosity distribution have a significant impact on the limit elastic speed in comparison to the aspect ratio.Practical implicationsThe study determines a range of operable speeds for porous and non-porous disk profiles that the industry can utilize to estimate structural performance.Originality/valueA finite element investigation was conducted to validate the findings of the present study. Limit elastic analysis of porous FG disks under thermo-mechanical loading has not been studied before.
