Comprehensive analysis identifies histone 2A ubiquitination as a marker for aging and pan-cancer prognosis
Authors: Zhang Fen , Wang Zhan , Zhang Jiahang , Zhou Menghao , Chen Yongxia , Zhang Sainan , Sun Zeyu , Ji Feiyang
Published: July 2022

Ubiquitination is a post-translational modification (PTM) that induces protein degradation or function alteration and plays crucial roles in aging and cancer. Previous ubiquitinomes of aging mainly focused on how ubiquitination changes in drosophila and other lower animals, but how ubiquitination changes during the aging of higher animals and what causes these changes remain unclear. Here, we profiled whole-life ubiquitinome data of mouse brain, heart, liver, muscle, and spleen, and integratively analyzed the ubiquitinome data with RNA sequencing data. The results showed that the ubiquitination of protein, especially histone 2A (H2A), changed intensely during aging due to the regulated expression of E3 ligases (E3s) and deubiquitylating enzymes (DUBs). Then we developed two distinct H2A’ E3s/DUBs expression subtypes with different prognosis, DNA damage response (DDR), and tumor microenvironment cell infiltration degrees based on an unsupervised method in pan-cancer. In conclusion, our study provided temporal resolution ubiquitinome data of mouse aging and revealed the vital role of H2A ubiquitination in aging and tumor progression.

, was synthesized. The single-crystal X-ray diffraction analysis shows that the polymeric structure crystallizes in the centrosymmetric monoclinic C2/c space group. The ZnII atom is coordinated to two S and two N atoms from four crystallographically independent (L) ligands, forming zigzag chains along the [001] direction. This polymer complex forms an eight-membered [Zn–S–C–N–Zn–S–C–N] chair-like ring with two ZnII atoms and two ligand molecules. On the Hirshfeld surface, the largest contributions come from the short contacts such as van der Waals forces, including H...H, C...H and S...H. Interactions including N...H, O...H and C...C contacts were also observed; however, their contribution to the overall stability of the crystal lattice is minor.

Published: July 2022

A new polymorph of the title compound, C14H8Br3N3O2, (form-2) was obtained in the same manner as the previously reported form-1 [Akkurt et al. (2022). Acta Cryst. E78, 732–736]. The structure of the new polymorph is stabilized by a C—H...O hydrogen bond that links molecules into chains. These chains are linked by face-to-face π–π stacking interactions, resulting in a layered structure. Short inter-molecular Br...O contacts and van der Waals interactions between the layers aid in the cohesion of the crystal packing. In the previously reported form-1, C—H...Br interactions connect molecules into zigzag chains, which are linked by C—Br...π interactions into layers, whereas the van der Waals interactions between the layers stabilize the crystal packing of form-2. Hirshfeld molecular surface analysis was used to compare the intermolecular interactions of the polymorphs.

The sensitivity of the Gini to changes in group sizes and mean incomes: an extension of ANOGI applied to Brazil
Authors: Mendes Loureiro Pedro
Published: July 2022

Purpose

The purpose of this paper is to first develop indicators for how total inequality, measured through the ANalysis Of GIni (ANOGI) framework, is mapped onto each group – i.e. indicators for each group's share of total inequality. Second, to develop indicators for the sensitivity of total inequality and its structure to changes in the composition of the population. Specifically, to develop indicators for how the Gini index and its ANOGI components react to (1) changes in the population-share of each group, (2) migration between groups, (3) changes in group incomes and (4) income transfers between groups.

Design/methodology/approach

First, the expressions for these indicators are derived analytically. Following this, the indicators are applied to labour-market data from Brazil, contrasting the results to others available in the literature.

Findings

The indicators described above are presented and their characteristics discussed. Empirically, it is illustrated how labour formalisation in Brazil was an inequality-reducing process between 2002 and 2011, contrary to previous incorrect measurements of the phenomenon based on income-source decompositions for Latin American countries.

Originality/value

Indicators for how total inequality reacts to changes in group sizes and income were unavailable for the ANOGI framework, which this article provides. The empirical illustration shows how this leads to a reassessment of important inequality dynamics, using the example of labour formalisation in Brazil. Contrary to the existing literature, it is shown how this was a progressive development, with key implications for social and labour-market policy. This framework can be used to assess the impact of diverse processes in the ANOGI methodology.
How job complexity fosters employee creativity: a contextualized growth perspective and the mechanism of feedback-seeking
Authors: Yang Wa , Zhu Jinqiang , Xu Shiyong , Liu Yanjun , Luo Dongying , Wang Yixiao , Yu Jia
Published: July 2022

Purpose

Drawing on the work design growth model (WDGM), this paper aims to explore the relationship between job complexity and employee creativity through feedback-seeking and the moderating effect of team leaders with a growth creative mindset.

Design/methodology/approach

The authors used an online survey to test the hypotheses. Data was collected in three waves from 74 supervisors and 349 paired employees in China.

Findings

Job complexity had a positive association with employees’ feedback-seeking, which further linked to employee creativity. This indirect effect was stronger in work teams with leaders endorsing a growth creative mindset.

Practical implications

Job complexity has become prevalent in organizations today. Taking daily complexity as a resource for nurturing employee creativity may balance organizations’ costs on formal training and give them more initiatives in long-term development. In addition, as the growth creative mindset is relatively easy to assess and change, it may bring insights in terms of creativity development.

Originality/value

By empirically testing the behavioural mechanism of WDGM, the learning and development perspective of work design offers a new explanation of the relationship between job complexity and employee creativity. The authors further extend WDGM by identifying leaders’ growth creative mindset to be a boundary condition.

Authors: Momoh Job , Medjdoub Benachir , Ebohon Obas John , Ige Olubisi , Young Bert Ediale , Ruoyu Jin
Published: July 2022

Purpose

Sustainable urbanism is the study of both cities and the practices to build them, which focusses on promoting their long-term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place. This paper analyses the implications of adopting sustainable urbanism principles and developing resilient places with Abuja as the area of focus to tackle the highlighted issues.

Design/methodology/approach

The paper is based on qualitative research which is centred on an extensive literature review and archival retrieval of historical documents. This includes the emergence of urbanism, sustainable urbanism definition and current issues surrounding its adaptation. The paper also focusses on a case study area in the capital city of Abuja, Nigeria which is currently undergoing massive urban development. Interviews are conducted with academics (13), practitioners (12) and government officials (10) making a total of 35 participants.

Findings

The main findings will create an understanding of the definition of sustainability and sustainable urbanism with a special focus on Abuja city. It was realised from the interviews that sustainable urbanism in broad terms encompasses economic, social, and environmental sustainability, and that these dimensions vary across different contexts even in the developing world. Also, sustainability can be achieved through deploying the right combination of measures, policies, assessment tools, sustainability assessment, good governance, and training/education and incentives.

Originality/value

By reviewing the selected studies which explore a wide range of disciplines and research areas, and conducting this qualitative research, this paper shares insights into how sustainability and sustainability urbanism can be achieved in the development of urban spaces in Abuja environs.
Corporate governance, litigation risk and firm performance: a mediation moderating model
Authors: Waheed Abdul , Mahmood Hamid , Wen Jun
Published: July 2022

Purpose

The purpose of this research is to investigate how the negative effect of litigation risk on firm performance could be controlled through the channel of voluntary disclosure and under the condition of institutional ownership.

Design/methodology/approach

To get the objectives, the study analyzed an unbalanced panel of 918 non-financial listed Chinese firms from 2010 to 18. To capture any expected unobserved heteroscedasticity and autocorrelation in the unbalanced sample, the authors have applied fixed effect regression with robust standard errors clustered at the firms' levels as suggested by Newey and West (1987).

Findings

The research provides that the good disclosure practices and presence of institutional ownership in corporations raise the trust of the investors by making the corporate operation clear in the eyes of the stakeholders. This increases the corporate credibility and as consequence corporations are protected against litigation risk. Thus, in the light of the information asymmetry and signaling theories, voluntary disclosure practices, and financial institutions' ownership, bridges the information gap and transmit a positive signal in the market regarding the better financial performance of the corporations.

Research limitations/implications

These findings are helpful for the corporate managers for effective strategic decisions, regulatory authorities for policy formulation, and individual investors for developing a diversified investment portfolio.

Originality/value

By applying the mediation and moderation effects, the research enhances the understanding of the underlying causes of the association between a firm's litigation risk and its performance. The current research contributes to the literature, that agency issues which create litigation risk could be settled internally with voluntary disclosure practices and externally with institutional ownership.
Residents' waste mobile recycling planned behavior model: the role of environmental concern and risk perception
Authors: Chang Yong-Sheng , Yue Zhang , Qureshi Madeeha , Rasheed Muhammad Imran , Wu Song , Peng Michael Yao-Ping
Published: July 2022

Purpose

The purpose of this research is to investigate the relationships of environmental concern and risk perception with residents' waste mobile recycling behavior in the scenario of continuously increasing electronic waste (aka e-waste) around the world.

Design/methodology/approach

For empirically testing proposed research model, this study utilized convenience sampling strategy and collected 346 responses from residents in the People’s Republic of China (PRC) through an online survey. The hypotheses were tested utilizing the structural equation modeling (SEM) framework through Mplus 7.0 program (Muthen and Muthen, 1998–2012). Robust maximum likelihood (MLR) was used as the method of estimation.

Findings

The results revealed that environmental concern is positively associated with individuals' intentions to recycle waste mobile phones and that the relationship between concern for the environment and individuals' intention to recycle is mediated by the factors such as individuals' mobile phone recycling attitude and subjective norms. The results further indicated that individuals' information security risk perception moderates the relationship between individuals' intention for recycling and subsequent recycling behavior.

Originality/value

This study provides substantial theoretical and practical implications for residents' e-waste recycling behavior while considering their environmental concern and information security risk perceptions.
Determinants of foreign direct investment: employment status and potential of food processing industry in India
Authors: Padhi Satya Prasad
Published: July 2022

Purpose

The paper underpins an advanced domestic manufacturing that comes with some advanced employment specialization status of individual industries as the key determinant of foreign direct investment (FDI) and considers how FDI in the food processing industry in India relates to this focal point.

Design/methodology/approach

This paper investigates how inward FDI inflows relate to domestic investment and revival in the industry using Auto Regressive Distributed lags (ARDL) model over the period 2000–2017. The model allows for different specifications to study whether FDI is responsible for the revival or the prior revival induces the FDI.

Findings

The results show the lack of proper advanced specialized employment status of the food processing industry. FDI in food processing is mainly guided by exports and imports opportunities and FDI plays no role in the revival of advanced growth in the industry. This finding explains why FDI in the industry is predominantly service sector oriented.

Originality/value

The paper underlines (1) the proper conceptualization of human capital as an important determinant of FDI; (2) reinterpretation of Kaldor's technical progress function that uncovers how employment dynamics embedded in intermediate goods specializations play a key role in supporting a higher pace of investment (and FDI); (3) labor costs' importance should involve not only the wage rate but also the advantages that a specialized employment base and (4) FDI in manufacturing demands a greater policy focus on developing domestic bases of intermediate goods specializations.
Addressing sexual and reproductive health and rights with men in prisons: co-production and feasibility testing of a relationship, sexuality and future fatherhood education programme
Authors: Robinson Martin , Templeton Michelle , Kelly Carmel , Grant David , Buston Katie , Hunt Kate , Lohan Maria
Published: July 2022

Purpose

Young incarcerated male offenders are at risk of poorer sexual health, adolescent parenthood and lack opportunities for formative relationship and sexuality education (RSE) as well as positive male role models. The purpose of this paper is to report the process of co-production and feasibility testing of a novel, gender-transformative RSE programme with young male offenders to encourage positive healthy relationships, gender equality, and future positive fatherhood.

Design/methodology/approach

Using a rights-based participatory approach, the authors co-produced an RSE programme with young offenders and service providers at two UK prison sites using a sequential research design of: needs analysis, co-production and a feasibility pilot. Core components of the programme are grounded in evidence-based RSE, gender-transformative and behaviour change theory.

Findings

A needs analysis highlighted the men’s interest in RSE along with the appeal of film drama and peer-group-based activities. In the co-production stage, scripts were developed with the young men to generate tailored film dramas and associated activities. This co-production led to “If I Were a Dad”, an eight-week programme comprising short films and activities addressing masculinities, relationships, sexual health and future fatherhood. A feasibility pilot of the programme demonstrated acceptability and feasibility of delivery in two prison sites. The programme warrants further implementation and evaluation studies.

Originality/value

The contribution of this paper is the generation of an evidence-based, user-informed, gender-transformative programme designed to promote SRHR of young male offenders to foster positive sexual and reproductive health and well-being in their own lives and that of their partners and (future) children.

Authors: Shokeen Ekta , Katirci Nihal , Williams-Pierce Caro , Bonsignore Elizabeth
Published: July 2022

Purpose

This study aims to understand children’s sketching behavior while they engage in interest-driven design activities. Particularly, the authors examine their information sharing practices and the learning opportunities that may occur when they engage in a sketching activity.

Design/methodology/approach

The data collection is based on a participatory design approach, cooperative inquiry. For analysis, the authors used the ethnographic case study approach, which allowed us to consider the particularity and complexity of sketching and its affordances within each distinct design activity.

Findings

The authors found children share information about their expectations, experiences, beliefs and knowledge via their sketches. Additionally, through sketching activities, they were engaged in multiple learning opportunities including how to label sketches, build on ideas, sketch in collaboration and innovate on ideas.

Research limitations/implications

The findings demonstrate sketching can be used to gather information about the broader contexts of children’s lives which can be leveraged to identify their needs and improve the design of future technologies for children. Additionally, participating in sketching gives children opportunities to develop their sketching skills, a useful multimodal skillset for both design and personal expression.

Originality/value

This empirical research is original in its context of focusing on children sketching experiences in an interest-driven design environment occurring virtually in the informal setting of a library.
Mementos from digital worlds: video game photography as documentation
Authors: Urban Alex C.
Published: July 2022

Purpose

Video game players, equipped with image capturing and rendering features, are taking photographs within digital worlds. This study examines video game photography as a documentary practice. By considering the experiences of a gamer-turned-photographer, this study offers an initial synthesis of this new document phenomenon and provides considerations for categorizing such photos.

Design/methodology/approach

To discover the attributes of video game photography, this study utilized an auto-hermeneutic approach with self-interviewing and picture-sorting techniques. The resulting data were analyzed using interpretative phenomenological analysis.

Findings

Without tangible artifacts to commemorate gaming experiences, photographs empower the player to document and artistically reconstruct moments from purely digital worlds. The three themes from this study's findings – that video game photographs act as (1) vehicles for storytelling, (2) creative trophies, and (3) aesthetic tokens – reveal how personally meaningful documents emerge from this medium. Furthermore, the findings uncover the fuzzy boundaries between play, artwork, and documentation.

Practical implications

This study explores techniques for categorizing in-game photographs and eliciting gameplay memories. The methods outlined may assist video game researchers, conservators, and archivists with organizing photographs as context materials.

Originality/value

By considering the lived experiences between one individual and their video game photographs, this study expands document theory into the underrepresented hobby of video games.
Understanding hosts’ task performance antecedents in e-rentals
Authors: Barbeitos Iolanda , Oliveira Tiago
Published: July 2022

Purpose

When evaluating a booking enquiry, hosts rely on peer-to-peer (P2P) accommodation platforms (P2PAP) to make an informed decision. Consequently, accepting or rejecting a booking is influenced by the capacity of the P2PAP to convey to hosts valuable information about guests. This study aims to explain hosts’ task performance in short-term rentals (e-rentals).

Design/methodology/approach

The proposed model explains hosts’ task performance in e-rentals as a combination of task-specific user capabilities and technology capabilities. The model was tested using the partial least square path modelling technique.

Findings

Task-specific user capabilities of covert observation and interrogation were found to have a positive influence on task performance. Moreover, a moderation effect of representation on the relationship between self-disclosure and task performance was found to be significant, yet contrary to the one hypothesized.

Originality/value

The findings from this study help to develop the concept of task-specific user capabilities in shaping task performance.
Global path planning of unmanned vehicle based on fusion of A* algorithm and Voronoi field
Authors: Zhao Jiansen , Ma Xin , Yang Bing , Chen Yanjun , Zhou Zhenzhen , Xiao Pangyi
Published: July 2022

Purpose

Since many global path planning algorithms cannot achieve the planned path with both safety and economy, this study aims to propose a path planning method for unmanned vehicles with a controllable distance from obstacles.

Design/methodology/approach

First, combining satellite image and the Voronoi field algorithm (VFA) generates rasterized environmental information and establishes navigation area boundary. Second, establishing a hazard function associated with navigation area boundary improves the evaluation function of the A* algorithm and uses the improved A* algorithm for global path planning. Finally, to reduce the number of redundant nodes in the planned path and smooth the path, node optimization and gradient descent method (GDM) are used. Then, a continuous smooth path that meets the actual navigation requirements of unmanned vehicle is obtained.

Findings

The simulation experiment proved that the proposed global path planning method can realize the control of the distance between the planned path and the obstacle by setting different navigation area boundaries. The node reduction rate is between 33.52% and 73.15%, and the smoothness meets the navigation requirements. This method is reasonable and effective in the global path planning process of unmanned vehicle and can provide reference to unmanned vehicles’ autonomous obstacle avoidance decision-making.

Originality/value

This study establishes navigation area boundary for the environment based on the VFA and uses the improved A* algorithm to generate a navigation path that takes into account both safety and economy. This study also proposes a method to solve the redundancy of grid environment path nodes and large-angle steering and to smooth the path to improve the applicability of the proposed global path planning method. The proposed global path planning method solves the requirements of path safety and smoothness.
The impact of brand familiarity, perceived trust and attitude on investors’ decision-making in Islamic stock market
Authors: Md Husin Maizaitulaidawati , Aziz Shahab , Bhatti Tariq
Published: July 2022

Purpose

This paper aims to investigate the influence of investors’ attitudes on their decision-making. Two subjective perception factors, brand familiarity and perceived trust, were proposed to influence investors’ attitudes and decision-making. This paper also suggests the potential mediating effect of attitude on decisions on Islamic stock investment.

Design/methodology/approach

Data were collected using a primary data collection method. Questionnaires were used and distributed to a sample size of 250 Malaysian investors in the Klang Valley aged between 25 and 50 years old. Data were analysed using SPSS and Structural Equation Modelling–Partial Least Squares.

Findings

Seven hypotheses were proposed, and six were supported. The findings show that brand familiarity and perceived trust have a significant relationship with attitude. Brand familiarity and attitude have a significant relationship with investment decision behaviour. The relationship between perceived trust and attitude also reveals significant findings. However, perceived trust was found to have an insignificant relationship with investment decision behaviour. Mediation analysis shows that attitude mediates the relationship between brand familiarity and investment decision behaviour. Attitudes are also found to mediate the relationship between perceived trust and investment decision behaviour.

Practical implications

It is recommended that publicly listed companies emphasize and devote extra efforts to enhancing investors' familiarity with and favour their brand. In addition, to build an investor’s trust, a company must be consistent in dividend payments. Such action may improve the probability of the company’s stock being chosen for investment.

Originality/value

Subjective perceptions of investors' decision-making in Islamic stock investment have yet to be thoroughly explored in the literature, especially in the Malaysian context. In this paper, the indirect relationship between brand familiarity and perceived trust in attitude is tested. This paper contributes to consumer behaviour and marketing of Islamic stock investment research area.
Numerical study on buckling capacity of steel H-beams under non-uniform temperature distribution
Authors: Nguyen Thac Quang , Nguyen Xuan Tung , Nguyen Tri N. M. , Bui-Tien Thanh , Park Jong Sup
Published: July 2022

Purpose

The 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/approach

A 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.

Findings

The 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/value

This 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.

Bangladesh is facing a high rate depletion of traditional energy sources. Renewable energy technology may be an alternative solution to meeting Bangladesh’s rising energy demand. Despite huge potential, Bangladesh fails to use renewable energy sources properly due to insufficient information and technical knowledge. The present research studied the current energy condition and potentiality of renewable energy with its influence on economic growth in Bangladesh.

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

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.

Published: July 2022

Purpose

RF 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/approach

After 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.

Findings

The 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/value

The 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

Purpose

This 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/approach

The conceptual model was tested using a nationwide survey from 430 Australian customers of Uber, using structural equation modeling.

Findings

Results 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/implications

Cross-sectional data were used. Thus, the results only provide a snapshot of the relationships among constructs.

Practical implications

To 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/value

Building 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

Purpose

This 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/approach

Questions 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.

Findings

Numerous 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/value

This 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.
