Authors: Nguyen Thac Quang , Nguyen Xuan Tung , Nguyen Tri N. M. , Bui-Tien Thanh , Park Jong Sup 
Published: July 2022

PurposeThe strength and stiffness of steel deteriorate rapidly at elevated temperatures. Thus, the characteristics of steel structures exposed to fire have been concerned in recent years. Most studies on the fire response of steel structures were conducted at uniformly distributed temperatures. This study aims to evaluate the buckling capacity of steel H-beams subjected to different loading conditions under non-uniform heating.Design/methodology/approachA numerical investigation was conducted employing finite element analysis software, ABAQUS. A comparison between the numerical analysis results and the experimental data from previous studies was conducted to verify the beam model. Simply supported beams were loaded with several loading conditions including one end moment, end equal moments, uniformly distributed load and concentrated load at midspan. The effects of initial imperfections were considered. The buckling capacities of steel beams under fire using the existing fire design code and the previous study were also generated and compared.FindingsThe results showed that the length-to-height ratio and loading conditions have a great effect on the buckling resistance of steel beams under fire. The capacity of steel beams under non-uniform temperature distribution using the existing fire design code and the previous study can give unconservative values or too conservative values depending on loading conditions. The maximum differences of unconservative and conservative values are −44.5 and 129.2% for beams subjected to end equal moments and one end moment, respectively.Originality/valueThis study provides the buckling characteristics of steel beams under non-uniform temperature considering the influences of initial imperfections, length-to-height ratios, and loading conditions. This study will be beneficial for structural engineers in properly evaluating structures under non-uniform heating conditions.
Customer service co-creation literacy for better service value: evidence from the health-care sector
Authors: Pham Tram-Anh Ngoc , Le Hau Nguyen , Nguyen Dung Tien , Pham Thuy Ngoc 
Published: July 2022

Purpose
Understanding customers’ expertise for better service co-creation is of great importance. To be an effective co-creator, customers need to have much more knowledge than a basic literacy, which is appropriate for passive service consumption. This paper aims to propose the concept of customer service co-creation literacy (SCL) to capture not only the basic expertise but also the expertise for active service co-creation. This study then investigates how SCL can be cultivated and how it facilitates customer co-creation behavior, which subsequently leads to enhanced value.

Design/methodology/approach
A conceptual model was developed and tested in the health-care service context using a sample of 310 patients. CB-SEM/AMOS software package was used for data analysis.

Findings
SCL has different impacts on three components of co-creation behavior, which in turn influence the service value differently. SCL not only solely facilitates co-creation behavior but also directly increases customer value. SCL can be cultivated by social support and frontline employee interaction.

Practical implications
The findings offer managerial and societal implications for cognitive interventions to develop customers’ SCL, which is aligned to customers’ needed literacy for co-creation and well-being.

Originality/value
The newly proposed concept of SCL is shown to be more appropriate in research adopting the service-dominant logic. Its importance as one type of customer operant resource for value co-creation is underscored. Findings also uncover how other actors indirectly contribute to customers’ value co-creation via developing their SCL resources.

Design/methodology/approach
This study analyzes the relationship between renewable energy consumption and economic growth of Bangladesh for the period of 2001–2016, based on yearly data, by using multiple regression model where augmented Dickey–Fuller unit root test has been chosen for testing the viability.

Findings
The result of this study showed that economic growth of Bangladesh is influenced positively by the consumption of renewable energy.

Practical implications
In addition, SWOT analysis has also done to develop a roadmap, and suggest some policies which will be able to accomplish the country’s climbing energy demands for a short- and long-term solution.

Originality/value
This study is an original work for Bangladesh, showing the results of the relationship between renewable energy consumption and economic growth. Therefore, this research will be useful to contribute to the literature review in the near future.
Unpacking capabilities for professional learning: teachers’ reflections on processes of collaborative inquiry in situated teamwork
Authors: Lysberg Julie 
Published: July 2022

Purpose
The purpose of this study is to gain insight into and understand the authentic lived experience of the processes of collaborative inquiry in teamwork from the perspective of teachers.

Design/methodology/approach
Data comprises stimulated recall interviews and semi-structured interviews. Seventeen teachers from four different teams in four schools form the empirical basis.

Findings
The analysis reveals that a shared focus on students’ learning in teachers’ processes of collaborative inquiry results in awareness and increased knowledge of what constitutes students’ learning. Thus, teachers are potentially becoming better equipped to facilitate students’ learning by offering them a richer set of learning opportunities. Findings confirm the key role of critical reflection through bringing teachers’ assumptions about teaching and learning to the surface, available for common exploration. When exploring problems of practice and sharing ideas and suggestions for possible solutions, teacher teams operate in a collective zone of proximal development.

Practical implications
This analysis of teachers’ reflections on the processes of collaborative inquiry supports school leaders and facilitators of school development by revealing fundamental and often hidden characteristics of teamwork collaboration.

Originality/value
Findings about teachers’ professional learning through collaborative inquiry in teamwork enhance knowledge about how teachers learn in authentic settings, and unpack the capabilities of teachers to author their own pedagogical changes. This study thus challenges linear models of professional development and the idea of professional development as mainly delivery-based.
Audit committee members’ proximity to corporate headquarters and audit fees
Authors: Firoozi Maryam , Magnan Michel 
Published: July 2022

Purpose
This study aims to investigate how audit committee members’ geographical location relative to corporate headquarters affects audit fees. The motivation for the paper rests on the observation that regulatory and market trends have significantly affected the composition of boards of directors and audit committees. To ensure that audit committees play their monitoring role, regulations now require directors’ independence and some level of financial expertise. The need to find directors who meet these requirements, as well as the advent of globalization and technological improvements lead firms to expand their reach when looking for directors.

Design/methodology/approach
The authors use a sample of 1,517 firm-year observations of Canadian firms from 2008 to 2017. The study relies on multivariate analyses.

Findings
The results show that, among nonlocal audit committee members, the presence of foreign directors is associated with higher audit fees. In contrast, other nonlocal audit committee members do not have a differential impact on audit fees. This effect is more prevalent in large firms. Moreover, having a foreign chair of the audit committee as well as foreign audit committee members who are not accounting experts appear to accentuate the increase in audit fees. A possible explanation for the finding is that, from the supply side, auditors assign a higher risk to firms with a higher percentage of foreign audit committee members. Alternatively, from the demand side, firms with foreign audit committee members may ask for more audit effort. Further analysis indicates that having a higher percentage of foreign audit committee members is associated with a higher likelihood of restatements, an indication of low audit quality.

Originality/value
To the best of the authors’ knowledge, this study is the first to document that auditors price the location of audit committee members and consider it when planning for their audit.
Board independence and firm internationalization: a meta-analysis
Authors: Spadafora Ettore , Addo Kwabena Aboah , Kostova Tatiana , Kumodzie-Dussey Makafui Kwame , Leo Ezekiel , Marano Valentina , van Essen Marc 
Published: July 2022

Purpose
Despite agency theory and resource dependence theory suggesting that – albeit through different mechanisms – board independence positively influences firm internationalization, empirical evidence on this relationship has been mixed and inconclusive. Based on this, the purpose of the present study is twofold: first, to analyze and synthesize the existing empirical literature and, second, to develop new theoretical insights on the effect of board independence on firm internationalization.

Design/methodology/approach
The authors used advanced meta-analytic techniques that allowed them, first, to synthesize the existing empirical literature on the board independence–firm internationalization relationship and, second, to examine the effect of several contingencies on such relationship. This study relies on data from 87 primary studies (published and unpublished) carried out in multiple academic fields in the period 1998–2021 and covering 49 countries.

Findings
The results confirm the established agency and resource-dependence arguments, suggesting that higher board independence is associated with greater firm internationalization. Moreover, the results show that the focal relationship is moderated by home-country formal and informal institutional factors, and in particular, the legal protection of minority shareholders and family business legitimacy. The authors do not find evidence that CEO duality and board size moderate the focal relationship or that board independence has a stronger effect on breadth than on depth of internationalization.

Originality/value
This study lies at the intersection of the literatures on corporate governance and firm internationalization and on comparative corporate governance of the multinational firm, shedding further light on the role played by institutional environments in determining the effectiveness of corporate governance mechanisms.
Polyimide substrate textured by copper-seeding technique for enhanced light absorption in flexible black silicon
Authors: Omar Halo Dalshad , Abdulkadir Auwal , Hashim Md. Roslan , Pakhuruddin Mohd Zamir 
Published: July 2022

Purpose
This paper aims to present investigation on textured polyimide (PI) substrate for enhanced light absorption in flexible black silicon (bSi).

Design/methodology/approach
Flexible bSi with thickness of 60 µm is used in this work. To texture the PI substrate, copper-seeding technique is used. A copper (Cu) layer with a thickness of 100 nm is deposited on PI substrate by sputtering. The substrate is then annealed at 400°C in air ambient for different durations of 60, 90 and 120 min.

Findings
With 90 min of annealing, root mean square roughness as large as 130 nm, peak angle of 24° and angle distribution of up to 87° are obtained. With this texturing condition, the flexible bSi exhibits maximum potential short-circuit current density (Jmax) of 40.33 mA/cm2, or 0.45 mA/cm2 higher compared to the flexible bSi on planar PI. The improvement is attributed to enhanced light scattering at the flexible bSi/textured PI interface. The findings from this work demonstrate that the optimization of the PI texturing via Cu-seeding process leads to an enhancement in the long wavelengths light absorption and potential Jmax in the flexible bSi absorber.

Originality/value
Demonstrated enhanced light absorption and potential Jmax in flexible bSi on textured PI substrate (compared to planar PI substrate) by Cu-seeding with different annealing durations.

Authors: Faheem Muhammad Yasir , Azeem Muhammad Basit , Minhas Abid Ali , Zhong Shun'an , Wang Xinghua 
Published: July 2022

PurposeRF transceiver module is considered a vital part of any wireless communication system. This module consists of two important parts the RF transceiver and analog-to-digital converter (ADC). Usually, both these parts – RF transceiver and ADC – are used to enhance the perspective of size and power. The data processing in 4G communication makes hurdles and need research attention to make it faster and smaller in size. Accuracy and fast processing are the critical challenges in the modern communication system.Design/methodology/approachAfter theoretical and practical investigations, this research work proposes key new techniques for the RF transceiver module. These techniques will make RF transceiver small, power-efficient and on the other hand, make dual SAR-ADC more effective as well. The proposed design has no intermediate frequency where the RF transceiver is reduced its major blocks from five to four, which includes crystal oscillator, phase lock loop, power amplifier and low noise amplifier. Moreover, the shared circuitry is introduced in the architecture of the SAR-ADC for the production of dual outputs, specifically in bootstrapped switch and comparator.FindingsThe miniaturized RF transceiver and SAR-ADC are well tested separately before the plantation on the printed circuit board (PCB). The operating voltage and frequency of the RF transceiver module are 1.2 V and 5.8 GHz, where the sampling rate, bandwidth and output power are 25 MHz, 200 MHz and 5 dBm, respectively. The core area of the PCB is 58.13 mm2. The bandwidth efficiency is 93% using surface acoustic wave less transmitter. The circuit is based on the library of 90 nm CMOS technology.Originality/valueThe entire circuit is highly synchronized with the input and reference clocks to avoid self-interference.
Customer participation, innovative aspects of services and outcomes
Authors: Nyadzayo Munyaradzi W. , Leckie Civilai , Johnson Lester W. 
Published: July 2022

PurposeThis study aims to investigate how customers' perception of service innovation aspects (innovativeness, service newness and relative advantage) and their participation impact value perception, satisfaction and loyalty.Design/methodology/approachThe conceptual model was tested using a nationwide survey from 430 Australian customers of Uber, using structural equation modeling.FindingsResults show that customer participation (CP) and innovativeness positively influence perceived value. Satisfaction is positively influenced by perceived value, innovativeness and relative advantage. Both perceived value and satisfaction drive loyalty. Yet, CP did not influence satisfaction. The study’s findings generally support the mediating roles of perceived value and satisfaction.Research limitations/implicationsCross-sectional data were used. Thus, the results only provide a snapshot of the relationships among constructs.Practical implicationsTo promote loyalty, service organizations emphasize how innovative aspects of services (innovativeness and relative advantage) can create value and satisfaction. Also, CP is critical in promoting customer perceived value and loyalty.Originality/valueBuilding on service-dominant logic (SDL), this study proposes a conceptual model investigating how perceived innovative aspects of service and CP influence perceived value, satisfaction and loyalty of service organizations.
Everyday life information seeking in South Korea during the COVID-19 pandemic: daily topics of information needs in social Q&A
Authors: Kim Heejun , Oh Sanghee 
Published: July 2022

PurposeThis study investigated information needs on COVID-19 by identifying topics discussed on social questions and answers (Q&A) about daily routines, problems, and health issues for survival. A layered model of contexts for everyday life information seeking (ELIS) was adapted for interpreting topics to better understand the contexts in which users could relate information needs.Design/methodology/approachQuestions and answers posted on Naver Knowledge-iN were collected and analyzed during the first nine months following the outbreak. Time distribution, topic modeling, and association rule mining were applied to examine the topics on COVID-19 and their temporal variation.FindingsNumerous topics related to the cognitive context (symptoms and masks) and situational contexts (international affairs, financial support, study, and work) were discovered. Topics related to social context were discussed moderately, but the number of questions on this topic increased with time. Strong associations were observed between terms related to symptoms, indicating their importance as a COVID-19 topic in health.Originality/valueThis study investigated topics of information needs using social Q&A data in which not only information inquiry but also information sharing coexist. The findings can help bridge the theory of ELIS to topic modeling in practice. The insights gained from this study can be used by information service providers for developing guidance and programs about how to survive during a pandemic.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/OIR-10-2021-0547.
Structural pluralism and incivility: comparing patterns of moral foundations and incivility in responses to news posts
Authors: Kim Bumsoo 
Published: July 2022

PurposeFocusing on the sociological clarification based on structural pluralism, this study explores the degree to which social media users who comment on the news posts of local newspapers use uncivil remarks and words that reflect their moral foundations.Design/methodology/approachThis computer-assisted data collection produces three types of datasets that include numerous social media comments. To explore the association between moral foundations and incivility, both quadratic association procedure (QAP) and multiple regression QAP (MRQAP) are implemented.FindingsThe findings suggest that social media users who comment on the news posts of urban-located newspapers tend to use more uncivil words compared to social media users who comment on the news posts of suburban and rural-based newspapers. Individuals who comment on the news posts of urban-based newspapers tend to show a wider range of moral foundation spectrums than those who comment on the posts of rural and suburban newspapers. Lastly, there are significant associations between moral-vice components and incivility in response to urban- and suburban-located newspapers' social media posts.Research limitations/implicationsThe employed bag-of-words may not completely capture incivility given that social media users can use nuanced and metaphoric terms instead of explicitly uncivil terms. Even though this study systematically selected local newspapers' social media accounts, the contextual factors of other newspapers in politically slanted communities could be different.Practical implicationsThe findings of this study provide meaningful and practical implications for journalists and news reporters. The inherent rudeness and aggressiveness of social media users can drive them to use uncivil and moral-harm words against a particular person or group.Social implicationsUnder the circumstance that fake news and politically slanted news content are widely distributed in the United States, social media users may easily express negative emotions toward news stories or the journalists who post the stories.Originality/valueStructural pluralism particularly specializes in explaining why and how the contextual factors of news stories differ depending on community complexity. Building on the reasoning of structural pluralism in the social media context, this study investigates the degree to which social media users who comment on the news posts of local newspapers employ uncivil remarks and moral foundation words.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/OIR-11-2020-0522.
