Nonplanar integrated correlator in
N=4
SYM
Authors: Zhang Shun-Qing 
Published: July 2024

The integrated correlator of four superconformal stress-tensor primaries in SU(N) N=4 super Yang-Mills (SYM) theory in the perturbative limit takes a remarkably simple form, where the L-loop coefficient is given by a rational multiple of ζ(2L+1). In this paper, we extend the previous analysis of expressing the perturbative integrated correlator as a linear combination of periods of f-graphs, graphical representations for loop integrands, to the nonplanar sector at four loops. At this loop order, multiple zeta values make their first appearance when evaluating periods of nonplanar f-graphs, but cancel nontrivially in the weighted sum. The remaining single zeta value, along with the rational number prefactor, makes a perfect agreement with the prediction from supersymmmetric localization.

We have investigated the magnetic ground state properties of the quantum spin trimer compound strontium hydroxy copper chloride SrCu(OH)3Cl using bulk magnetization, specific heat measurements, nuclear magnetic resonance (NMR), and electron spin resonance (ESR) spectroscopy. SrCu(OH)3Cl consists of layers with isolated Cu2+ triangles and hence provides an opportunity to understand the magnetic ground state of an isolated system of S = 1/2 arranged on an equilateral triangle. Although magnetization measurements do not exhibit a phase transition to a long-range ordered state down to T = 2 K, they reveal the characteristic behavior of isolated trimers with an exchange of J=154 K. The Curie-Weiss behavior changes around 50–80 K, as is also seen in the NMR spin-lattice relaxation rate. In zero magnetic field, our specific heat data establish a second-order phase transition to an antiferromagnetic ground state below T= 1.2 K. We have drawn a magnetic field-temperature (H−T) phase diagram based on the specific heat measurements. The ESR data show divergence of the linewidth at lower temperatures, which precedes the phase transition to an antiferromagnetic long-range ordered state with unconventional critical exponents. The temperature variation of the g-factor further confirms the antiferromagnetic phase transition and reflects the underlying magnetocrystalline anisotropy of the compound.

Reconciling mean-squared radius differences in the silver chain through improved measurement and
ab initio
calculations

Published: July 2024

Nuclear charge radius differences in the silver isotopic chain have been reported through different combinations of experiment and theory, exhibiting a tension of two combined standard errors. This study investigates this issue by combining high-accuracy calculations for six low-lying states of atomic silver with an improved measurement of the 5s2S1/2−5p2P3/2 transition optical isotope shift. Our calculations predict measured electronic transition energies in Ag at the 0.3% level, the highest accuracy achieved in this system so far. We calculate electronic isotope shift factors by employing analytical response relativistic coupled-cluster theory and find that a consistent charge radius difference between Ag107,109 is returned when combining our calculations with the available optical isotope shift measurements. We therefore recommend an improved value for the mean-squared charge radius difference between Ag107 and Ag109 as 0.207(6) fm2, within one combined error from the value derived from muonic Ag experiments, and an updated set of charge radii differences across the isotopic chain.

Klebsiella pneumoniae (Kp) is an infectious disease pathogen that poses a significant global health threat due to its potential to cause severe infections and its tendency to exhibit multidrug resistance. Understanding the enzymatic mechanisms of the oxygen-insensitive nitroreductases (Kp-NRs) from Kp is crucial for the development of effective nitrofuran drugs, such as nitrofurantoin, that can be activated as antibiotics. In this paper, three crystal structures of two Kp-NRs (PDB entries 7tmf/7tmg and 8dor) are presented, and an analysis of their crystal structures and their flavin mononucleotide (FMN)-binding mode is provided. The structures with PDB codes 7tmf (Kp-NR1a), 7tmg (Kp-NR1b) and 8dor (Kp-NR2) were determined at resolutions of 1.97, 1.90 and 1.35 Å, respectively. The Kp-NR1a and Kp-NR1b structures adopt an αβ fold, in which four-stranded antiparallel β-sheets are surrounded by five helices. With domain swapping, the β-sheet was expanded with a β-strand from the other molecule of the dimer. The difference between the structures lies in the loop spanning Leu173–Ala185: in Kp-NR1a the loop is disordered, whereas the loop adopts multiple conformations in Kp-NR1b. The FMN interactions within Kp-NR1/NR2 involve hydrogen-bond and π-stacking interactions. Kp-NR2 contains four-stranded antiparallel β-sheets surrounded by eight helices with two short helices and one β-sheet. Structural and sequence alignments show that Kp-NR1a/b and Kp-NR2 are homologs of the Escherichia coli oxygen-insensitive NRs YdjA and NfnB and of Enterobacter cloacae NR, respectively. By homology inference from E. coli, Kp-NR1a/b and Kp-NR2 may detoxify polynitroaromatic compounds and Kp-NR2 may activate nitrofuran drugs to cause bactericidal activity through a ping-pong bi-bi mechanism, respectively.
Disassembling the components of virtual clothing presentation: exploring their impact on consumers' perception and purchase intention
Authors: Dai Siyi , Xiao Ping , Li Huimin 
Published: July 2024

PurposeVirtual clothing presentation has a visual 3D effort and allows consumers to interact. Currently, most scholars make virtual clothing presentations as a whole or focus on one element to study its impact on consumers’ purchase intentions. This study disassembles the components of virtual clothing presentation in Taobao and explores how each component (virtual clothing, virtual model, presentation space, presentation technology and system quality) affects consumers’ purchase intention, which can provide clothing companies recommendations for developing it and help improve consumers’ online shopping experience.Design/methodology/approachThis study created the parts of a virtual clothing presentation and took advantage of Taobao’s 3D interactive module to simulate a shopping scenario. Participants experienced a 3D interactive virtual clothing presentation in which they could change clothing colors, show actual clothing sizes, try different model poses, switch presentation backgrounds and unfold clothing structure through interactive buttons. Then they were randomly assigned to view two kinds of images and videos of experiment clothing (real images and videos vs virtual ones), respectively. Hypotheses were tested using SEM and applying SmartPLS 4.FindingsThe results demonstrated that five components of virtual clothing presentation have different degrees of influence on consumers’ purchase intention through different consumer perceptions (perceived usefulness, ease of use and enjoyment). It is necessary to consider the design of the virtual clothing presentation in those five dimensions for different needs. In addition, it is feasible to replace images and animated videos of real clothing with virtual ones in Taobao.Originality/valueDifferent types of virtual clothing presentations can lead to various results in terms of diverse impacts. This study disassembles and researches each component of a virtual clothing presentation. Overall, this study could provide guidance and suggestions for clothing companies to develop and design or invest in virtual clothing presentations.
Can artificial intelligence produce a convincing accounting research article?
Authors: du Toit Elda 
Published: July 2024

Purpose
This study aims to establish whether accounting research articles can be potentially generated by artificial intelligence. If artificial intelligence can produce quality work, the integrity of academic research may be compromised.

Design/methodology/approach
ChatGPT was used to create a paper on a meta-analysis of the relationship between sustainability reporting and value relevance. After the paper was generated, references had to be added by hand based on the citations created by ChatGPT. The paper was then presented as-is for review.

Findings
ChatGPT was able to create a relatively good-quality research paper that received two major revisions from independent specialists in the field of accounting and finance. Even though there is uncertainty regarding the appropriateness of all the references and the results cannot be confirmed, there is a risk that a reviewer may find the paper publishable because reviewers are not compelled to check references and the accuracy of results if proper methods were used that appear to be sufficient at face value.

Originality/value
Artificial intelligence for academic writing is still relatively new, and there is still significant uncertainty as to the impact it may have on scholarly research. This is especially problematic because artificial intelligence applications improve by the second.
Exploring the relationship between team institutional composition and novelty in academic papers based on fine-grained knowledge entities
Authors: Chen Ziling , Zhang Chengzhi , Zhang Heng , Zhao Yi , Yang Chen , Yang Yang 
Published: July 2024

Purpose
The composition of author teams is a significant factor affecting the novelty of academic papers. Existing research lacks studies focusing on institutional types and measures of novelty remained at a general level, making it difficult to analyse the types of novelty in papers and to provide a detailed explanation of novelty. This study aims to take the field of natural language processing (NLP) as an example to analyse the relationship between team institutional composition and the fine-grained novelty of academic papers.

Design/methodology/approach
Firstly, author teams are categorized into three types: academic institutions, industrial institutions and mixed academic and industrial institutions. Next, the authors extract four types of entities from the full paper: methods, data sets, tools and metric. The novelty of papers is evaluated using entity combination measurement methods. Additionally, pairwise combinations of different types of fine-grained entities are analysed to assess their contributions to novel papers.

Findings
The results of the study found that in the field of NLP, for industrial institutions, collaboration with academic institutions has a higher probability of producing novel papers. From the contribution rate of different types of fine-grained knowledge entities, the mixed academic and industrial institutions pay more attention to the novelty of the combination of method indicators, and the industrial institutions pay more attention to the novelty of the combination of method tools.

Originality/value
This paper explores the relationship between the team institutional composition and the novelty of academic papers and reveals the importance of cooperation between industry and academia through fine-grained novelty measurement, which provides key guidance for improving the quality of papers and promoting industry–university–research cooperation.

Published: July 2024

PurposeThis study dwells into the crucial aspects of gig workers' jobs that are absent, with specific focus on the work life of food delivery workers (FDWs) and how it impacts their work happiness.Design/methodology/approachTo create a conceptual model, 21 delivery workers were first interviewed, and the data gathered were scrutinized. Subsequently, a questionnaire was sent to 493 delivery partners, probing about their opinions of work factors that could affect their level of happiness. The collected data were put to study by the authors using AMOS and SPSS.FindingsFive missing work components were revealed by qualitative investigation. The absence of voice, recognition, career growth, work satisfaction, and dignity at work contributed to unhappiness of the workers. The qualitative analysis was supported by quantitative findings. Additionally, company policy moderated the relationship between absence of voice, absence of career growth, absence of job satisfaction and absence of work happiness.Originality/valueTo the best of the authors’ knowledge, this is one of the first studies using a mixed-method approach to identify factors contributing to the unhappiness of FDWs in work. The originality of this study also lies in establishing the moderating influence of company policy on the relationship between the absence of voice, absence of career growth, absence of work satisfaction and absence of workplace happiness among the workers.

Published: July 2024

PurposeIn several developing contexts, the delivery of Architecture, Engineering Construction and Operation (AECO) projects continually grapples with issues such as fragmented communication, a lack of transparency, safety and risk management concerns. These problems result from the use of traditional construction practices and insufficient technology integration. Therefore, there is a pressing need to enhance communication, transparency and collaboration within construction projects in these countries through the improved utilization of innovative tools. Consequently, this study empirically assesses both the application areas and the benefits associated with the adoption of social media within the Nigerian construction industry.Design/methodology/approachThis study employed a quantitative research approach that utilized a structured questionnaire to collect responses from construction professionals. The respondents were selected using a combination of purposive and snowball sampling techniques, resulting in a 75% response rate. Data analysis included mean score value (MSV), standard deviations and normality testing (Shapiro-Wilk) to assess data characteristics. The Kruskal-Wallis H-test was used for further analysis due to the ordinal nature of the data.FindingsThe findings of this study indicate that social media can be effectively used in project management, communication, safety management, as well as marketing and branding of AECO projects. The most significant benefits of using social media in construction activities include building trust and credibility, enhancing crisis communication and improving project collaboration.Originality/valueThis study introduces a fresh perspective by showcasing the transformative potential of social media, traditionally viewed as a communication tool, in addressing complex issues in construction project delivery. Consequently, the findings of this study can offer a paradigm shift in the way construction professionals, policymakers and industry stakeholders perceive and harness the capabilities of social media.

Published: July 2024

PurposeThe focus of this article is in documentation in substance abuse inpatient rehabilitation. Our article scrutinizes how workers give accounts of the documentation in the inpatient substance abuse rehabilitation unit and what kind of client information the workers record.Design/methodology/approachThe study focuses on institutional interaction and practices. Our data consist of interviews with substance abuse rehabilitation professionals (N = 15). We analyzed the interviews using content analysis and the account concept in keeping with the ethnomethodological research tradition.FindingsStudy shows how workers account for the significance of documentation. Workers deemed documentation significant in four different ways: in gathering basic and rehabilitation information, in storing and transmitting information, as a tool for analysis and assessment and in supporting linguistic transparency in substance abuse rehabilitation. Workers justified the significance of documentation by the legal requirement to record information about clients. Documented information enables clear management of client information and supports substance abuse rehabilitation work in various ways. Documentation contains descriptions of the client’s situation and work performed. Additionally, documentation serves as a tool for communication among social care professional.Originality/valueThus the research show that documentation plays a significance part in the inpatient substance abuse rehabilitation and are connected to its institutional tasks and practices.
Do the fraud triangle components fuel complex financial fraud? A study of nonfinancial firms in Pakistan
Authors: Shahzadi Kinza , Alim Wajid , Khan Salleh Nawaz 
Published: July 2024

Purpose
Financial fraud is a severe corporate fraud committed for achieving various objectives, like attaining financial targets, lowering debt and providing good signals to the market. Such financial fraud deceives stakeholders and results in substantial financial losses. This study aims to detect financial fraud using the modified Beneish M-Score, the most appropriate forensic tool for fraud detection. Furthermore, the current study also examines the influential role of the fraud triangle’s elements (pressure, opportunity and rationalization) on financial fraud in nonfinancial firms during 2018–2021, offering insight for understanding and mitigating fraudulent activities in the corporate world.

Design/methodology/approach
Financial fraud is treated as a dependent variable measured through a modified Beneish M-score, while the fraud triangle elements (pressure, opportunity and rationalization) are measured through six proxies, which are financial stability, leverage, financial target, nature of the industry, the effectiveness of supervision and auditor changes.

Findings
The study's finding proclaimed that fraud triangle elements result in financial fraud. Findings unveil that all elements (pressure, opportunity and rationalization) of the fraud triangle significantly influence financial fraud. The study confirms that these elements must be considered to protect investors and provide a safe environment for investment.

Originality/value
Rare literature found addressing the detection of financial fraud and its nexus with the fraud triangle specifically in Pakistan where deficient governance is notably prevalent. This study attempts to fill such a gap and contribute to knowledge.
Ethical discourse of ethical (Islamic) finance: a systematic literature review (1988–2022) and the way forward
Authors: Shamsudheen Shinaj Valangattil , Mohamad Shamsher , Muneeza Aishath , Mahomed Ziyaad 
Published: July 2024

Purpose
This paper aims to portray the publication pattern, key themes, study trends and future directions for the studies on ethics in Islamic finance. A total of 194 published documents that includes journal articles, books and book chapters and conference proceedings were screened for the period 1988 to August 2022 and categorized based on designated sectors of the Islamic finance industry. This paper also highlights the change in research trends in all three sectors of Islamic finance and suggests possible areas for future research.

Design/methodology/approach
A comprehensive systematic literature review was conducted using the “advanced search” function of “google scholar” by using the option “find articles” with the keywords “Ethic (s/al)”, “Islamic banks”, “Islamic banking”, “Islamic finance”, “Islamic capital markets” Takaful, Islamic insurance without restricting the time frame, author list and the platform. Furthermore, the search for relevant articles was conducted on other mainstream index databases such as “Web of Science” and “Scopus”.

Findings
Among the highlights of the findings were an increase in publications on ethical issues after the global financial crisis and an increase in publications in high-impact mainstream business and finance journals. A higher number of studies were documented in the area of Islamic banking and finance followed by Islamic capital markets and Islamic insurance/Takaful. Although a greater number of empirical studies were published than conceptual studies, dominance was resulted due to the replication of the studies in various jurisdictions based on the same concepts or models rather than applying diversified concepts in various jurisdictions.

Originality/value
This study contributes to the growing literature on ethical and/or Islamic finance as a guide for researchers to identify research gaps and provides a systematic direction for future studies in the area of ethics in Islamic finance.
