Spatiotemporal Proteomics Deciphers Functional Selectivity of EGFR ligands
Authors: Eguchi Akihiro , Emdal Kristina B. , Ye Zilu , Guzmán Ulises H. , Olsen Jesper V.
Published: September 2023

The epidermal growth factor receptor (EGFR) induces different signaling outputs depending on ligand identity and biological context. This phenomenon is known as functional selectivity, but the underlying molecular mechanisms remain elusive. Here, we investigated this on a global scale and time-resolved by high-throughput multilayered proteomics integrating dynamic changes in the EGFR interaction network by proximity biotinylation using EGFR- TurboID, phosphoproteome, and proteome in response to stimulation with the six highest-affinity EGFR ligands. We obtained comprehensive temporal profiles of protein recruitment and phosphosite changes pinpointing signaling proteins differentially regulated by the six ligands with key impact on EGFR endocytic fate, e.g. degradation or recycling. Specifically, the Epsin family protein, Clint1 was identified to control the endocytic trafficking of EGFR towards degradation. Moreover, we characterized the protein interaction selectivity of EGFR C-terminally phosphorylated tyrosine residues using a panel of tyrosine mutated constructs showing STAT5 specificity for EGFR Y1173. These data provide a comprehensive resource deciphering functional selectivity of EGFR signaling to support discovery of novel drug targets.
Crystal structure of a 1:1 co-crystal of quabodepistat (OPC-167832) with 2,5-dihydroxybenzoic acid using microcrystal electron diffraction
Authors: Sakamoto Nasa , Gato Katsuhiko
Published: September 2023

Quabodepistat [(5-{[(3R,4R)-1-(4-chloro-2,6-difluorophenyl)-3,4-dihydroxypiperidin-4-yl]methoxy}-8-fluoro-3,4-dihydroquinolin-2(1H)-one); C21H20ClF3N2O4] and 2,5-dihydroxybenzoic acid (2,5DHBA; C7H6O4) were successfully co-crystallized. Given the small size of the crystals (1 × 0.2 × 0.2 µm) the structure was solved via microcrystal electron diffraction (MicroED). The C—O and C=O bond-length ratio of the carboxylic group in 2,5DHBA is 1.08 (1.34 Å/1.24 Å), suggesting that 2,5DHBA remains protonated. Therefore, the material is a co-crystal rather than a salt. The amide group of quabodepistat participates in a cyclic hydrogen bond with the carboxylic group of the 2,5DHBA. Additional hydrogen bonds involving the quabodepistat amide and hydroxyl groups result in a three-dimensional network.

Authors: Koay Kian Yeik , Leong Mei Kei
Published: September 2023

Purpose

The purpose of this study is to examine the factors influencing consumers' intentions to use drone food delivery services from the perspective of the theory of consumption values (TCV).

Design/methodology/approach

Data collection involves the utilisation of self-administered questionnaires. Subsequently, 305 data were gathered from Malaysian consumers and subjected to analysis through partial least squares structural equation modelling (PLS-SEM).

Findings

This study demonstrated that functional, social, emotional and epistemic values, as well as personal innovativeness, can strongly predict intentions. However, neither the conditional value nor environmental concerns were significant predictors of intentions.

Originality/value

The study is the first of its kind to use the TCV from the perspective of a developing country to understand consumers' intentions to use drone food delivery services.
Years of education and research driven in sustainable architecture: Where do we stand and where do we go?
Authors: Sheta Wael
Published: September 2023

Purpose

The purpose of this study is to give an informative map of sustainable architectural education by focusing on publishing trends, prominent publications, prolific contributors, research challenges and future research prospects. As a consequence, an efficient framework for collecting significant knowledge and identifying prevalent topics in sustainable architectural education towards more sustainable environments at the urban and building scales may be provided.

Design/methodology/approach

The methodology adopted in this study is based on examining the subjects of many consecutive rounds of the Passive and Low Energy Architecture (PLEA) conference, with an emphasis on the most recent five rounds. The PLEA's official website served as the main source for gathering all proceedings. Earlier rounds from 2016 to 2020, which cover a time span of five years, were utilized to analyze patterns during that time period. The rationale for selecting this time period was the limited availability of data required to observe the trends, area of interest and emerging themes in these fields that could be analyzed qualitatively.

Findings

The findings show that the following drive themes emerged around education and research-driven sustainable architecture: emerging design as a core idea; concentration on the way of delivering and developing education; constructing and shaping the building; assessing current practices; acquiring and recruiting knowledge and new concepts; reporting on the current condition; portraying the target audience and ensuring the long-term viability of the architectural educational process. This insight provides academics and professionals a greater grasp of the state of the art, allowing them to direct their research toward developing concerns in education and research-driven sustainable design.

Originality/value

The study results provide an effective framework for collecting relevant content and identifying prominent topics in sustainable, passive and passive low-energy architecture for the creation of more sustainable urban and building environments. Furthermore, this qualitative and exploratory study may serve as a framework for those researching, creating and verifying different research approaches in education and research-driven sustainable architecture.
Busy CEOs and audit fees: evidence from Indonesia
Authors: Harymawan Iman , Putri Fiona Vista , Ratri Melinda Cahyaning , Nasih Mohammad
Published: September 2023

Purpose

A company needs to use auditing procedures to ensure the reliability of financial statements while also providing transparency to stakeholders. The extent of risk associated with the company depends on the directors’ involvement in its daily operations. This paper aims to study the relationship between busy chief executive officers (CEOs) and audit fees.

Design/methodology/approach

This study uses 1,037 data samples from companies listed on the Indonesia Stock Exchange from 2010 until 2018. It adopts the ordinary least squares method to test the hypothesis. Furthermore, this study performs robustness tests, such as propensity score matching (PSM) and Heckman’s two-stage least square tests (Heckman, 1979), to address the endogeneity issues.

Findings

This study finds that the appearance of a busy CEO in a company will significantly increase the audit fee. It also concludes that a long tenure of a busy CEO will substantially weaken the positive relationship between the CEO and the audit fee. However, this study discovers that, in a company with a busy CEO, a monitoring mechanism through the independent commissioner and risk management committee will only help to maximize the firm’s practical risk evaluation a little. This result is robust because the PSM and Heckman tests display consistent results, so it is free from endogeneity issues.

Practical implications

This study is valuable for theoretical and practical development in Indonesia. Due to the minimum regulation about multiple positions on boards in Indonesia, the shareholders must be aware of the need to choose a board with more skill and commitment to improve the position of the company. This result also warns the C-level of the company to pay more attention to its risk-monitoring process to make it more effective and efficient.

Originality/value

Indonesia is one of the countries that have implemented the two-tier governance system. With the minimum regulation about multiple directorships in Indonesia, this study offers new insights into how a busy CEO will be related to the audit outcomes.
An intellectual design case of compressor airfoils based on reinforcement learning
Authors: Xu Xiaohan , Huang Xudong , Zhang Ke , Zhou Ming
Published: September 2023

Purpose

In general, the existing compressor design methods require abundant knowledge and inspiration. The purpose of this study is to identify an intellectual design optimization method that enables a machine to learn how to design it.

Design/methodology/approach

The airfoil design process was solved using the reinforcement learning (RL) method. An intellectual method based on a modified deep deterministic policy gradient (DDPG) algorithm was implemented. The new method was applied to agents to learn the design policy under dynamic constraints. The agents explored the design space with the help of a surrogate model and airfoil parameterization.

Findings

The agents successfully learned to design the airfoils. The loss coefficients of a controlled diffusion airfoil improved by 1.25% and 3.23% in the two- and four-dimensional design spaces, respectively. The agents successfully learned to design under various constraints. Additionally, the modified DDPG method was compared with a genetic algorithm optimizer, verifying that the former was one to two orders of magnitude faster in policy searching. The NACA65 airfoil was redesigned to verify the generalization.

Originality/value

It is feasible to consider the compressor design as an RL problem. Trained agents can determine and record the design policy and adapt it to different initiations and dynamic constraints. More intelligence is demonstrated than when traditional optimization methods are used. This methodology represents a new, small step toward the intelligent design of compressors.
Investigation on smoothed finite element methods using linear tetrahedral elements for high-speed train hollow axle strength analysis
Authors: Jiang Chen , Odibelu Ekene Paul , Zhou Guo
Published: September 2023

Purpose

This paper aims to investigate the performance of two novel numerical methods, the face-based smoothed finite element method (FS-FEM) and the edge-based smoothed finite element method (ES-FEM), which employ linear tetrahedral elements, for the purpose of strength assessment of a high-speed train hollow axle.

Design/methodology/approach

The calculation of stress for the wheelset, comprising an axle and two wheels, is facilitated through the application of the European axle strength design standard. This standard assists in the implementation of loading and boundary conditions and is exemplified by the typical CRH2 high-speed train wheelset. To evaluate the performance of these two methods, a hollow cylinder cantilever beam is first used as a benchmark to compare the present methods with other existing methods. Then, the strength analysis of a real wheelset model with a hollow axle is performed using different numerical methods.

Findings

The results of deflection and stress show that FS-FEM and ES-FEM offer higher accuracy and better convergence than FEM using linear tetrahedral elements. ES-FEM exhibits a superior performance to that of FS-FEM using linear tetrahedral elements, showing accuracy and convergence close to FEM using hexahedral elements.

Originality/value

This study channels the novel methods (FS-FEM and ES-FEM) in the static stress analysis of a railway wheelset. Based on the careful testing of FS-FEM and ES-FEM, both methods hold promise as more efficient tools for the strength analysis of complex railway structures.
Digitalization and bank profitability: evidence from an emerging country
Authors: Nguyen Quang Thi Thieu , Ho Ly Thi Hai , Nguyen Dat Thanh
Published: September 2023

Purpose

This study aims to investigate the effect of digitalization on bank profitability among Vietnamese banks.

Design/methodology/approach

The research employs fixed-effects regression on a panel data of 32 banks in Vietnam during the period 2010–2021.

Findings

The study reveals a positive impact of digitalization on bank profitability. The result is robust to different measures and empirical settings. Not surprisingly, small banks and banks with high percentage of state ownership experience lower profitability than their peers. However, digitalization helps improve the profitability of these banks. This study explains the effect by showing that digitalization significantly reduces bank cost in terms of cost to income ratio and increases bank non-interest income through diversification into non-traditional products and services. In addition, the current stage of bank digitalization in Vietnam does not reduce banks’ employment costs since it requires staffs to support and operate the new system.

Practical implications

The research findings are motivations for bankers and policy-makers in designing appropriate strategies toward digitalization. Investors can also consider highly digitalized banks as valuable investment.

Originality/value

This research extends the current literature on the relationship between digitalization and bank profitability, with a focus on commercial banks in Vietnam. Given the high involvement of the government and the dominance of several large banks in the banking system, the study also explores whether the effect of digitalization on bank profitability varies with the bank’s size and state ownership. Last but not least, the channels in which digitalization affects bank profitability are also examined.
Eliciting social themes of flood mitigation and community engagement studies through text mining
Authors: Egbelakin Temitope , Omotayo Temitope , Ogunmakinde Olabode Emmanuel , Ekundayo Damilola
Published: September 2023

Purpose

Flood preparedness and response from the perspective of community engagement mechanisms have been studied in scholarly articles. However, the differences in flood mitigation may expose social and behavioural challenges to learn from. This study aimed to demonstrate how text mining can be applied in prioritising existing contexts in community-based and government flood mitigation and management strategies.

Design/methodology/approach

This investigation mined the semantics researchers ascribed to flood disasters and community responses from 2001 to 2022 peer-reviewed publications. Text mining was used to derive frequently used terms from over 15 publications in the Scopus database and Google Scholar search engine after an initial output of 268 peer-reviewed publications. The text-mining process applied the topic modelling analyses on the 15 publications using the R studio application.

Findings

Topic modelling applied through text mining clustered four (4) themes. The themes that emerged from the topic modelling process were building adaptation to flooding, climate change and resilient communities, urban infrastructure and community preparedness and research output for flood risk and community response. The themes were supported with geographical flood risk and community mitigation contexts from the USA, India and Nigeria to provide a broader perspective.

Originality/value

This study exposed the deficiency of “communication, teamwork, responsibility and lessons” as focal themes of flood disaster management and response research. The divergence in flood mitigation in developing nations as compared with developed nations can be bridged through improved government policies, technologies and community engagement.
Surmounting the gap: the impact of the COVID-19 pandemic on education for families in the Galapagos Islands
Authors: Carrick Oliver James
Published: September 2023

Purpose

The COVID-19 pandemic caused schools across the world to close their physical facilities and switch from face-to-face classes to remote learning. This research investigates the consequences of school closures during the pandemic on families and children from marginalized sections of society. The setting of the Galapagos Islands is characterized by poor Internet access and performance, resulting in a detrimental effect on the education of students from vulnerable sectors of society.

Design/methodology/approach

Using data from an empirical context, this case study seeks to enhance statistical results from a provincial level household survey with quantitative information from participatory development planning workshops and plans.

Findings

Statistical analysis evidences the compound effect of the COVID-19 pandemic on the more vulnerable families living in the Galapagos. Both economic wellbeing and children's ability to attend classes online during school closures were linked to respondents' education levels. Participatory development planning workshops highlighted further inequality, and the plans resultant from the process sought to overcome challenges and address needs by contextualizing education for sustainable island living.

Originality/value

This case study emphasizes the impact of school closures due to the COVID-19 pandemic on vulnerable sectors of society. In the Galapagos Islands, the response to the compound effect of the pandemic and the other situational challenges has been to contextualize the educational curriculum towards the goal of sustainable living. The lessons learned from this experience will be applicable to other remote island groups.
Compensations, overconfidence and use of loan terms
Authors: Voon Jan , Ma Yiu Chung
Published: September 2023

Purpose

This paper contributes to the literature as follows. First, it examines if option and stock compensations raise creditor's risk, and which one is more important than the other. Second, it explores if CEO's compensation interacts with CEO overconfidence to raise creditor's risk. Third, it investigates how banks use different loan terms to alleviate their credit risk.

Design/methodology/approach

This study used advanced regression analysis and use of generalized methods of moment methodology.

Findings

The results show that option compensation is more important than stock compensation in raising credit risk; option compensation interacts with CEO overconfidence, giving rise to a much higher credit risk; and covenant usage is more important than other loan contract terms in mitigating credit risk given that covenant use could not be substituted away by using other loan contract terms such as increasing interest rate, reducing principal or shortening loan duration. This paper has practical implications for credit markets.

Research limitations/implications

The main implication is that hand-collect data are available up to 2010.

Practical implications

It informs creditors the potential sources of loan risk emanating from option rather than stock incentives; it informs creditors that option incentive interacts with CEO overconfidence rendering the credit risk bigger than expected, and it informs creditors the importance of using covenants vis-à-vis other loan contract terms for mitigating compensation and overconfidence risk.

Social implications

Banks are alerted to the risk due to the interaction between overconfidence and compensations, implying that overconfident managers remunerated with options compensations are more risky than overconfident managers who are not remunerated as such.

Originality/value

This paper is original: (1) The authors show that option compensation is more risky than stock compensation from viewpoint of creditors. This has not been assessed. (2) Interaction between managerial compensation and managerial overconfidence has not been assessed before. (3) Use of different loan contract terms to alleviate risk from overconfident managers (who are prone to over investment but who are innovative according to the literature) has not been evaluated.
A systems approach to examine microentrepreneurship development through Stimulus-Organism-Behavior-Consequence (SOBC) theory
Authors: Panda Debadutta Kumar
Published: September 2023

Purpose

Microfinance programs across the countries are designed on the self-help and peer pressure model, aim at microentrepreneurship development. Despite of significant studies on microfinance-supported microentrepreneurship (MSM), not a single literature examines it from the systems thinking. In addition to that, the extant literature did not look MSM from the behavioral perspectives. To address the above gaps, the present study aims to examine self-help group (SHG)-based microfinance programs from the systems approach using the Stimulus-Organism-Behavior-Consequence (SOBC) model.

Design/methodology/approach

Information gathered from 786 women SHG members from four states of India through a structured interview schedule. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) were conducted to process data. Additional statistical tests were performed to test the reliability and validity.

Findings

It was found that the “positive stimulus” (social intermediation, financial intermediation and business development services) positively impacted; and “negative stimulus” (intermediation accountability, and intermediation assumption) negatively impact, to “motive” (attitude, subjective norms, and perceived control) for micro-entrepreneurship in the SHG-based microfinance. Further, “motive” positively predicted “behavioral intention”; the “behavioral intention” positively determined “consequences” of micro-entrepreneurship. Intermediation as stimuli acted as “input”; the motive and behavioral intention acted as the “process”, and the consequence acted as the “output” in the SHG-based microentrepreneurship system.

Originality/value

To the best of the author's knowledge, this paper is the first one to examine the behavioral systems of microentrepreneurship programs through the Stimulus-Organism-Behavior-Consequence (SOBC) model.

Combined SCD-SPSW system subjected to ground excitation
Authors: Boshagh Mohammad , Labibzadeh Mojtaba , Hosseinlou Farhad , Rezaeian Abbas
Published: September 2023

Purpose

In this study, the application of a novel combined steel curved damper (SCD) and steel plate shear wall (SPSW) system in the 5-, 10- and 15-storey steel moment-resisting frames (SMR) subjected to earthquake excitation has been investigated. The proposed system is called here as the SMR-WD (steel moment resisting–wall damper).

Design/methodology/approach

At the beginning of this research, an SMR-W and an SMR-D are separately modeled in ABAQUS software and verified against the available experimental data. After that, three different heights SMR-WD systems (5-, 10- and 15-storey) are designed and simulated. Then, their performances are examined and compared to the corresponding SMR-W under the effects of six actual earthquake records.

Findings

The obtained results show that the proposed system increases the mean values of the base shear for 5-, 10- and 15-storey SMR-WD equal to 27, 20.15 and 16.51%, respectively compared to the corresponding SMR-W. Moreover, this system reduces the drift of the floors so that the reduction in the average values of maximum drift for 5-, 10- and 15-storey SMR-WD is equal to 10, 7 and 29%, respectively with respect to the corresponding SMR-W. The results also reveal that the considered system dissipates more energy than SMR-W so that the increase in the mean values of the energy absorption for 5-, 10- and 15-storey SMR-WD is 30.8, 25.6 and 41.3%, respectively when compared to the SMR-W. Furthermore, it is observed that SMR-WD has a positive effect on the seismic performance of the link beams and panel zones of the frames. By increasing the height of the structure in the SMR-WD, the energy dissipation and base shear force increases and the drift of floors decreases. Hereupon, the proposed SMR-WD system is more useful for tall buildings than SMR-W frames.

Originality/value

For the first time, the application of a novel combined steel curved damper (SCD) and steel plate shear wall (SPSW) system in the 5-, 10- and 15-storey steel moment-resisting frames (SMR) subjected to earthquake excitation has been investigated.

Scoping the links between acquisitive crime, criminal predation and family business
Authors: Smith Robert
Published: September 2023

Purpose

The stereotypes of the dodgy businessman and businessman gangster are established typologies in both the criminology and family business literature, but nevertheless, there is still an evident dearth of substantive studies on the topic. Family business scholars have begun to acknowledge the limited nature of such explorations of criminality in family firm businesses. The purpose of this article is therefore to review, synthesise and solidify existing research on this under-researched area of family business management.

Design/methodology/approach

This perspective article explores and synthesises the links between acquisitive crime, criminal predation and family business to address an identifiable research gap in the literature of criminology, entrepreneurship and family business. It examines the overlap between criminal activities and business practices, shedding light on how individuals in the family business community may become involved in criminal activities due to various factors, including coercion, addiction and financial gain.

Findings

This perspective highlights emerging research trends that have the potential to increase the knowledge about the “dark side” of family business.

Research limitations/implications

Being a perspective paper this brief exploration of the literature can only cover a small cross section of the literature. A conceptual model emerges, which illustrates shared aspects of crimino-entrepreneurial identity between authentic entrepreneurs and criminals.

Originality/value

This perspective article scopes the extant literature covering the links between acquisitive crime, criminal predation and family business to help guide the direction of future research. The piece presents new perspectives on the intersection of acquisitive crime and family business, and its novelty lies in its synthesis of the disparate elements from the diverse literature to contribute to the said literature.

Authors: Cain Curtis C. , Buskey Carlos D. , Washington Gloria J.
Published: September 2023

Purpose

The purpose of this paper is to demonstrate the advancements in artificial intelligence (AI) and conversational agents, emphasizing their potential benefits while also highlighting the need for vigilant monitoring to prevent unethical applications.

Design/methodology/approach

As AI becomes more prevalent in academia and research, it is crucial to explore ways to ensure ethical usage of the technology and to identify potentially unethical usage. This manuscript uses a popular AI chatbot to write the introduction and parts of the body of a manuscript discussing conversational agents, the ethical usage of chatbots and ethical concerns for academic researchers.

Findings

The authors reveal which sections were written entirely by the AI using a conversational agent. This serves as a cautionary tale highlighting the importance of ethical considerations for researchers and students when using AI and how educators must be prepared for the increasing prevalence of AI in the academy and industry. Measures to mitigate potential unethical use of this evolving technology are also discussed in the manuscript.

Originality/value

As conversational agents and chatbots increase in society, it is crucial to understand how they will impact the community and how we can live with technology instead of fighting against it.

Breaking away from servitization paradox to improve manufacturing enterprises' service innovation performance: the roles of market orientation and service supply chain dynamic capability
Authors: Lyu Tu , Lyu Xiaorui , Chen Hao , Zhao Qiu
Published: September 2023

Purpose

Based on the dynamic capability theory, our study tries to explore the mediator mechanism of service supply chain dynamic capability between market orientation and service innovation performance, as well as the boundary conditions in which service supply chain dynamic capability plays a role, in order to reveal the key elements and their mechanisms for manufacturing enterprises to improve service performance.

Design/methodology/approach

With a total of 317 valid questionnaires, structural equation modeling (SEM) was used to test the research model and hypotheses.

Findings

The empirical results confirm that the three types of service supply chain dynamic capability (environment insight capability, resource integration capability and resource reconfiguration capability) can partially mediate the relationship between firm market orientation (responsive and proactive market orientations) and service innovation performance. In addition, supply chain collaboration has different types of moderator effects on the relationship between the three types of service supply chain dynamic capability and service innovation performance.

Originality/value

This research discovers that market orientation and dynamic capability are the key factors leading to high service performance and reveals the mediating role of service supply chain dynamic capability between market orientation and service innovation performance. Moreover, this research explores the moderating role of supply chain collaboration in service supply chain resource reconfiguration capability and service innovation performance.
Understanding learners' intention toward Metaverse in higher education institutions from a developing country perspective: UTAUT and ISS integrated model
Authors: Alkhwaldi Abeer F.
Published: September 2023

Purpose

The Metaverse is an immersive virtual world where individuals interact with each other using an avatar. The Metaverse is promised to offer several potentials for different sectors. While the Metaverse promotes innovative interaction between individuals (e.g. learners), there is a scarcity of knowledge on what influences its acceptance and use in higher educational institutions (HEIs), particularly in developing countries. Thus, this paper aims to identify the factors that affect the users' intentions toward Metaverse technology for educational purposes in the HEIs in Jordan.

Design/methodology/approach

A study model was created by incorporating variables from the unified theory of acceptance and use of technology (UTAUT) (performance expectancy, PE; effort expectancy, EE; social influence, SI; and facilitating conditions, FC) and information system success (ISS) model (user satisfaction, SAT; system quality, SQ; service quality, SVQ and information quality, IQ) with perceived curiosity (PC) and hedonic gratification (HG) constructs. Both PC and HG were added as context-related factors that could contribute to improving the applicability of UTAUT and ISS to a wide range of technology use contexts. Data were gathered from 441 Jordanian university students using an online questionnaire.

Findings

The analysis of the structural model revealed that users' behavioural intentions toward using Metaverse were significantly affected by user satisfaction (SAT), performance expectancy (PE), facilitating conditions (FC) and hedonic gratification (HG). Also, information quality (IQ) and services quality (SVQ) were revealed to have a significant influence on user satisfaction. Likewise, the results illustrated a significant impact of systems quality (SQ), information quality (IQ) and service quality (SVQ) on PE. Lastly, a significant effect of PC on the EE factor was found.

Practical implications

This study will shed light on a number of practical implications for developers, designers, service providers and decision-makers supporting the acceptance and adoption of the Metaverse technology in the educational context. Also, it will contribute to developing the right strategies, and Metaverse content which will draw the attention of learners.

Originality/value

As per the surveyed literature and the researcher's prior knowledge, this is one of the first studies that integrate the UTAUT model, ISS model and two contextual factors (PC and HG) besides testing the proposed model in a developing country (Jordan). This paper is one of the few in which the individuals' acceptance behaviour of Metaverse technology was examined in the HEIs context.
Patterns of artificial intelligence policies in China: a nationwide perspective
Authors: Wang Kaili , Dong Ke , Wu Jiachun , Wu Jiang
Published: September 2023

Purpose

The purpose of this paper is to identify the historical trends and status of the national development of artificial intelligence (AI) from a nationwide perspective and to enable governments at different administrative levels to promote AI development through policymaking.

Design/methodology/approach

This paper analyzed 248 Chinese AI policies (36 issued by the state agencies and 212 by the regional agencies). Policy bibliometrics, policy instruments and network analysis were used to reveal the AI policy patterns. Three aspects were analyzed: the spatiotemporal distribution of issued policies, the policy foci and instruments of policy contents and the cooperation and citation among policy-issuing agencies.

Findings

Results indicate that Chinese AI development is still in the initial phase. During the policymaking processes, the state and regional policy foci have strong consistency; however, the coordination among state and regional agencies is supposed to be strengthened. According to the issuing time of AI policies, Chinese AI development is in accordance with the global situation and has witnessed unprecedented growth in the last five years. And the coastal provinces have issued more targeted policies than the middle and western provinces. Governments at the state and regional levels have emphasized familiar policy foci and played the role of policymakers, along with regional governments that also functioned as policy executors as well. According to the three-dimension instruments coding, the authors found an uneven structure of policy instruments at both levels. Furthermore, weak cooperation appears at the state level, while little cooperation is found among regional agencies. Regional governments cite state policies, thus leading to the formation of top-down diffusion, lacking bottom-up diffusion.

Originality/value

The paper contributes to the literature by characterizing policy patterns from both external attributes and semantic contents, thus revealing features of policy distribution, contents and agencies. What is more, this research analyzes Chinese AI policies from a nationwide perspective, which contributes to clarifying the overall status and multi-level relationships of policies. The findings also benefit the coordinated development of governments during further policymaking processes.
Role of intra-ply hybridization and nano reinforcement on crack growth of epoxy
Authors: Ahmed Payman Sahbah
Published: September 2023

Purpose

Epoxy resins are widely used in a variety of engineering applications, including composite wind turbine blades used in the renewable energy industry, highly complex structural components for aircraft, paints, coatings, industrial tooling, biomedical systems, adhesives, electronics and automotive. Epoxies' low fracture toughness is one of the key obstacles preventing its adoption in a wider range of applications. To address epoxy's low fracture toughness, this paper aims to examine the roles of intra-ply hybridization and nano reinforcing.

Design/methodology/approach

This paper investigates the role of intra-ply hybridization of glass-carbon woven fibers and adding 0.8 wt.% of multiwall carbon nanotube (MWCNT) nano reinforcement to overcome the low fracture toughness of epoxy. A bending test is used to calculate the composites elastic parameters, and a notched sample three-point bending test is used to show crack behavior in addition to using materials characterization methods to reveal the effect of the MWCNT on structure, bonding, glass transition temperature (Tg) and dispersion of MWCNT in the matrix. Furthermore, this paper suggests using the finite element method to overcome the difficulty in calculating the crack extension.

Findings

Intra-ply hybridization and MWCNT reinforcement decrease the crack extension of epoxy with time. The inclusion of high-strength carbon fiber increased the fracture toughness of glass composite. Furthermore, the existence of MWCNT in the surrounding area of the notch in epoxy composites hinders crack propagation and provides stiffness at the interface by bridging the crack and eventually enhancing its fracture toughness.

Published: September 2023

Purpose

This paper aims to check the E-Government Development Index (EGDI) of South Asian countries and then highlight the main challenges they are facing right now, which are causing South Asian countries to do good in the e-government sector.

Design/methodology/approach

The authors will be getting the EGDI data for South Asian countries through the United Nations website, and to visualize it for understanding, the authors will be taking the help of an Online Business intelligence tool. After successfully fetching data and presenting it in a proper format, the authors will be doing an analysis of the South Asian country’s EGDI score overall and also will check on individual indicator levels of EGDI.

Findings

Finally, the authors will be sharing the common improvement points which South Asian countries’ governments need to focus on to make their EGDI score better and get included in the list of top E-Government. With its help, countries will progress and get hand-in-hand with the world by providing the best governance practices to their citizens.

Originality/value

It is important to understand for South Asian countries that the e-government initiative is not just about transforming governance or providing quality services to citizens but also it is about being in sync with the world and competing with other countries in the development progress. So, they have to follow the e-government trends to get their country aligned with the world and attain progress country in a faster speed.

Semen is a measure of the reproductive efficiency of roosters, which affects the economic benefits of white‐feathered broilers. Over the years, research in this field has mainly focused on hens, while there have been fewer studies on the reproductive traits of roosters. To identify the genes related to the semen traits of roosters, we used a chicken 55 K SNP chip to genetically type the white‐feathered population (220) and performed imputation with resequencing data from 97 roosters. In total, 1 048 576 SNPs were obtained and used for genome‐wide association analysis of semen volume, from which 197 genome‐wide significant markers were identified, all within the interval of 13.82–16.12 Mb on chromosome 7. By combining our results with the biological functions of genes in the interval, four candidate genes were identified that potentially relate to semen volume: FAPP1, OSBPL6, SESTD1 and SSFA2. Our findings may provide a basis for further research on the genetic mechanism and marker‐assisted selection of semen volume in white‐feathered broilers.

Objective

To undertake an economic evaluation of community water fluoridation (CWF) in remote communities of the Northern Territory (NT).

Design

Dental caries experiences were compared between CWF and non‐CWF communities before and after intervention. Costs and benefits of CWF are ascertained from the health sector perspective using water quality, accounting, oral health, dental care and hospitalisation datasets.

Setting and Participants

Remote Aboriginal population in the NT between 1 January 2008 and 31 December 2020.

Intervention

CWF.

Main Outcome Measures

Potential economic benefits were estimated by changes in caries scores valued at the NT average dental service costs.

Results

Given the total 20‐year life span of a fluoridation plant ($1.77 million), the net present benefit of introducing CWF in a typical community of 300–499 population was $3.79 million. For each $1 invested in CWF by government, the estimated long‐term economic value of savings to health services ranged from $1.1 (population ≤300) to $16 (population ≥2000) due to reductions in treating dental caries and associated hospitalisations. The payback period ranged from 15 years (population ≤300) to 2.2 years (population ≥2000).

Conclusions

The economic benefits of expanding CWF in remote Aboriginal communities of NT outweigh the costs of installation, operation and maintenance of fluoridation plants over the lifespan of CWF infrastructure for population of 300 or more.
The invisible other: Rituals and Egyptian perception of the unknowable
Authors: el‐Aswad el‐Sayed
Published: September 2023

This paper is positioned within broader scholarly debates about ritual‐religious and psychological elements underlying the phenomenon of altered states of mind in Egyptian Muslim contexts. This research examines the intricate relationships between ritual, consciousness, and the unseen/unknowable world reflected in the imagination and practices of urban and rural communities belonging administratively to the city of Tanta in Egypt. This comparative study proposes that the image of the embodied invisible Other, in both benevolent and malevolent forms, impacts the state of consciousness of persons participating in two different rituals, thezikr(remembrance of God) and thezār(the exorcism of spirits). This inquiry concentrates on the transformation of the states of people's consciousness, namely themajzūb(those mystically attracted to God) and themalbūs(those possessed by spirits), through embodied engagement with the invisible Other that is made visible through participation in the ritual performances of thezikrand/or thezār. Rituals performed by Egyptians, particularly those who experience altered states of consciousness, display both a psychic (emotional) experience and an encounter with the invisible Other that may be depicted as divine or otherwise non‐divine. Each case of thezikrritual andzārcult relates to its participants' perception of reality.
Beliefs about emotions predict psychological stress related to somatic symptoms

Published: September 2023

Background

Previous research has shown that the more people believe their emotions are controllable and useful (BECU), the less they generally report psychological distress. Psychological distress, in turn, impacts health outcomes, and is among the most frequently reported complaints in psychotherapeutic and psychosomatic practice.

Objective

We aimed to examine how BECU predicts psychological distress related to somatic symptoms in a prospective sample from the general population and to replicate this association in two cross‐sectional samples of psychosomatic patients.

Methods

We applied a panel design with an interval of 2 weeks between T1 and T2 in general‐population panel‐participants (N = 310), assessing BECU and psychological distress related to somatic symptoms via validated self‐report measures. Moreover, we cross‐sectionally replicated the relationship between BECU and psychological distress in a clinical sample of psychosomatic outpatients diagnosed with somatoform disorders (n = 101) or without somatoform disorders (n = 628).

Results

BECU predicted over and above the lagged criterion panel‐participants' psychological distress related to somatic symptoms, β = −.18, p < .001. BECU was also cross‐sectionally related to psychological distress in our clinical replication‐sample of psychosomatic outpatients diagnosed with somatoform disorders, rS(87) = −.33, p = .002 and in those without, rS(557) = ‐.21, p < .001.

Conclusions

BECU as a malleable way of thinking about emotions predicted psychological distress related to somatic symptoms in general‐population panel‐participants and correlated with the same in two clinical replication samples. BECU thus becomes a promising treatment target in psychotherapeutic approaches.
