Triply charm and bottom tetraquarks in a constituent quark model
Authors: Yang Gang , Ping Jialun , Segovia Jorge
Published: September 2024

Singly, doubly, and fully charmed tetraquark candidates, e.g., Tcs¯(2900), Tcc+(3875), and X(6900) have been recently reported by the LHCb collaboration. Therefore, it is timely to implement a theoretical investigation on triply heavy tetraquark systems; herein, the S-wave triply charm and bottom tetraquarks, Q¯Qq¯Q (q=u,d,s;Q=c,b), with spin-parity JP=0+, 1+, and 2+, isospin I=0 and 12, are systematically studied in a constituent quark model. Besides, all tetraquark configurations, i.e., meson-meson, diquark-antidiquark, and K-type arrangements, along with any allowed color structure, are comprehensively considered. The Gaussian expansion method (GEM), in combination with the complex-scaling method (CSM), which is quite ingenious in dealing with either bound or resonances, is the approach adopted in solving the complex scaled Schrödinger equation. This theoretical framework has already been applied in various tetra- and pentaquark systems. In a fully coupled-channel calculation within the GEM+CSM, narrow resonances are found in each I(JP) channel of the charm and bottom sector. In particular, triply charm and bottom tetraquark resonances are obtained in 5.6–5.9 GeV and 15.3–15.7 GeV, respectively. We provide also some insights of the compositeness of these exotic states, such as the inner quark distance, magnetic moment and dominant wave function component. All this may help to distinguish them in future high energy nuclear and particle experiments.

Thermal effects on sound velocity peak and conformality in isospin QCD
Authors: Chiba Ryuji , Kojo Toru , Suenaga Daiki
Published: September 2024

We study thermal effects on equations of state (EOS) in isospin QCD, utilizing a quark-meson model coupled to a Polyakov loop. The quark-meson model is analyzed at one-loop that is the minimal order to include quark substructure constraints on pions which condense at finite isospin density. In the previous study we showed that the quark-meson model at zero temperature produces the sound velocity peak and the negative trace anomaly in the domain between the chiral effective theory regime at low density and the perturbative QCD regime at high density, in reasonable agreement with lattice simulations. We now include thermal effects from quarks in the Polyakov loop background and examine EOS, especially the sound velocity and trace anomaly along isentropic trajectories. At large isospin density, there are three temperature windows; (i) the pion condensed region with almost vanishing Polyakov loops, (ii) the pion condensed region with finite Polyakov loops, and (iii) the quark gas without pion condensates. In the domain (i), the gap associated with the pion condensate strongly quenches thermal excitations. As the system approaches the domain (ii), thermal quarks, which behave as nonrelativistic particles, add energy density but little pressure, substantially reducing the sound velocity to the value less than the conformal value while increasing the trace anomaly toward the positive value. Approaching the domain (iii), thermal quarks become more relativistic as pion condensates melt, increasing sound velocity toward the conformal limit. Corrections from thermal pions are also briefly discussed.

Scattering of dark pions in Sp(4) gauge theory
Authors: Dengler Yannick , Maas Axel , Zierler Fabian
Published: September 2024

Analyses of astrophysical data provide first hints on the self-interactions of dark matter at low energies. Lattice calculations of dark matter theories can be used to investigate them, especially in the case of strongly interacting dark matter. We consider Sp(4) gauge theory with two fundamental fermions as a candidate theory. We compute the scattering phase shift for the scattering of two identical dark pions and determine the parameters of the effective range expansion. Our exploratory results in the supposedly most common interaction channel provide a lower limit for the dark matter mass when compared to astrophysical data. We also provide first benchmarks of velocity-weighted cross sections in the relevant nonrelativistic domain.

Exponential error reduction for glueball calculations using a two-level algorithm in pure gauge theory
Authors: Barca Lorenzo , Schaefer Stefan , Knechtli Francesco , Urrea-Niño Juan Andrés , Martins Sofie , Peardon Michael
Published: September 2024

This study explores the application of a two-level algorithm to enhance the signal-to-noise ratio of glueball calculations in four-dimensional SU(3) pure gauge theory. Our findings demonstrate that the statistical errors exhibit an exponential reduction, enabling reliable extraction of effective masses at distances where current standard methods would demand exponentially more samples. However, at shorter distances, standard methods prove more efficient due to a saturation of the variance reduction using the multilevel method. We discuss the physical distance at which the multilevel sampling is expected to outperform the standard algorithm, supported by numerical evidence across different lattice spacings and glueball channels. Additionally, we construct a variational basis comprising 35 Wilson loops up to length 12 and 5 smearing sizes each, presenting results for the first state in the spectrum for the scalar, pseudoscalar, and tensor channels.

Dark matter-electron scattering and freeze-in scenarios in the light of
Z′
mediation
Authors: Barman Basabendu , Das Arindam , Mandal Sanjoy
Published: September 2024

We investigate dark matter (DM-)electron scattering in a minimal U(1)X extension of the Standard Model (SM), where the DM can appear as a Majorana fermion, a complex singlet scalar, or a Dirac fermion. To study bounds on the U(1)X gauge coupling (gX) and new gauge boson mass (MZ′), from DM-electron scattering, we consider several direct search experiments like CDMS, DAMIC, SENSEI, PandaX-II, DarkSide-50, and XENON1T-S2 for different U(1)X charges. In this setup, we consider DM production via freeze-in in both radiation-dominated and modified cosmological background to project sensitivities onto gX−MZ′ plane satisfying observed relic abundance. DM-electron scattering could provide comparable, or even stronger, bounds compared to those obtained from the electron/muon (g−2), low-energy scattering, and intensity frontier experiments within 0.01  GeV≲MZ′≲0.1  GeV. Constrains from freeze-in could provide stronger sensitivities for MZ′≳O(1)  GeV; however, these limits are comparable to those obtained from LHCb and LEP experiments for O(10)  GeV≲MZ′≲150  GeV. In the future, electron-muon scattering (MUonE), proton (FASER and DUNE), and electron/positron (ILC) beam-dump experiments could probe these parameters.

Approaches to photon absorption in a Lorentz invariance violation scenario
Authors: Carmona J. M. , Cortés J. L. , Rescic F. , Reyes M. A. , Terzić T. , Vrban F. I.
Published: September 2024

Very high-energy astrophysical gamma rays suffer a suppression of their flux along their propagation due to their interaction, through the γγ→e+e− pair-production process, with the soft photon backgrounds present in the Universe. We examine the Universe’s transparency to gamma rays within a Lorentz invariance violation (LIV) framework, focusing on photon subluminal quadratic corrections driven by a high-energy scale. Based on an explicit calculation, we provide a new expression for the cross section that overcomes the limitations of previous approaches and refines existing constraints for the LIV scale, while we introduce a new approximation that may be useful in LIV scenarios beyond effective field theory. These improvements appear essential for setting constraints on LIV effects with future observations at ultrahigh energies, where previous approximations may fall short.

Upper limits on the cosmic neutrino background from cosmic rays
Authors: Císcar-Monsalvatje Mar , Herrera Gonzalo , Shoemaker Ian M.
Published: September 2024

Extragalactic and galactic cosmic rays scatter with the cosmic neutrino background during propagation to Earth, yielding a flux of relic neutrinos boosted to larger energies. If an overdensity of relic neutrinos is present in galaxies, and neutrinos are massive enough, this flux might be detectable by high-energy neutrino experiments. For a lightest neutrino of mass mν∼0.1  eV, we find an upper limit on the local relic neutrino overdensity of ∼1013 and an upper limit on the relic neutrino overdensity at TXS 0506+056 of ∼1010. Future experiments like GRAND or IceCube-Gen2 could improve these bounds by orders of magnitude.

Geometric quantum states beyond the AdS/CFT correspondence
Authors: Bousso Raphael , Kaya Sami
Published: September 2024

We characterize the quantum states dual to entanglement wedges in arbitrary spacetimes, in settings where the matter entropy can be neglected compared to the geometric entropy. In AdS/CFT, such states obey special entropy inequalities known as the holographic entropy cone. In particular, the mutual information of CFT subregions is monogamous (MMI). We extend this result to arbitrary spacetimes, using a recent proposal for the generalized entanglement wedge e(a) of a gravitating region a. Given independent input regions a, b, and c, we prove MMI: Area[e(a)]+Area[e(b)]+Area[e(c)]−Area[e(ab)]−Area[e(bc)]−Area[e(ca)]+Area[e(abc)]≤0. We expect that the full holographic entropy cone can be extended to arbitrary spacetimes using similar methods.

Universal fragmentation in annihilation reactions with constrained kinetics
Authors: Garcia Enrique Rozas , Karlsson Alfred Weddig , Hofmann Johannes
Published: September 2024

In reaction-diffusion models of annihilation reactions in low dimensions, single-particle dynamics provides a bottleneck for reactions, leading to an anomalously slow approach to the empty state. Here, we construct a reaction model with a reciprocal bottleneck of reactions on particle dynamics in which single-particle motion conserves the center of mass. We show that such a constrained reaction-diffusion dynamics does not approach an empty state but freezes at late times in a state with fragmented particle clusters. The late-time dynamics and final density are universal, and we provide exact results for the final density in the large-reaction rate limit. Thus, our setup constitutes a minimal model for the fragmentation of a one-dimensional lattice into independent particle clusters. We suggest that the universal reaction dynamics could be observable in experiments with cold atoms or in the Auger recombination of exciton gases.

Experiences of autistic people in supported employment in France: a participatory research project
Authors: Dachez Julie , Seksek Sylvie , Ete Natacha , Bianciotto Marc , Toubhans Marie-Pierre , Rachedi Nasri Zineb , Bureau Raven , Garnier Philippe
Published: September 2024

Purpose

The employment rate of autistic people is low, and they are often employed in low-paying jobs or in jobs involving tasks that fall short of their skills and competence. To address this situation, the individual placement and support method (IPS) offers promising perspectives for personalized and long-term support measures. This evidence-based method has produced positive results in several countries. IPS has been used in France only since 2016. This paper aims to examine the experience of autistic people in France who have benefitted from supported employment measures.

Design/methodology/approach

Nineteen autistic adults in France took part in semistructured interviews. Interview questions focused on work and measures to support employment. The authors analysed the interviews using reflexive thematic analysis, within the paradigm of critical realism. The authors adopted a participatory approach; the project was led by an autistic researcher and autistic individuals were included at all stages.

Findings

This study identified six primary themes and three subthemes across the data: (1) The uphill battle to obtain adjustments in the workplace; (2) insufficient knowledge of autism; (2.1) explaining again and again: the educative burden; (3) the challenge of making oneself heard; (3.1) when the entourage steps in; (4) support measures as material assistance and reassurance; (4.1) between benevolence and condescension; (5) organizational factors that affect the quality of support; and (6) personal and professional life are closely intertwined.

Originality/value

This research provides a better understanding of how autistic people experience supported employment in France and highlights ways to improve it. Job coaches play a crucial role in offering practical help and reassurance, and their efforts to nurture an active personal life are perceived positively. However, supported employment also carries the risk of limiting autistic individuals' capacity for action and causing several difficulties if job coaches are not well-informed about autism, do not reflect on their own attitudes, do not assist in obtaining necessary accommodations and if there are organizational problems leading to a lack of resources.
How management support and diversity factors affect employee performance within the digital workplace
Authors: Grzesiak Lena , Ulrych Wojciech
Published: September 2024

Purpose

We aimed to determine how remote management support (MS) practices and staff diversity influenced employee performance (EP) within the digital workplace (DW) during the COVID-19 pandemic. The article highlights the challenges managers face in achieving EP in the DW compared to traditional work environments.

Design/methodology/approach

We developed a theoretical model (MS→DW→EP) and tested it based on the computer-assisted web interview (CAWI) conducted in mid-2022. Factors of primary, secondary and organizational diversity moderated the relationship between the variables. We purposely selected a sample of 1,000 respondents with remote working experience.

Findings

The results show that the DW partially mediates the relationship between MS and EP. The greater the uncertainty in managing people, the more flexibility, trust and job satisfaction required in the DW to achieve EP. Organizational diversity influenced the model more (i.e. teamwork vs individual work) than the primary and secondary diversity (i.e. gender and education).

Research limitations/implications

Although the sample size was large, we cannot consider it statistically representative.

Practical implications

Zoomers and Millennials reflect full mediation in the model that supports EP.

Social implications

Broader work autonomy, smaller organizations and teams as well as hybrid work arrangements, reduce the necessity for in-person meetings with superiors.

Originality/value

Supervisors had to reduce control over the DW while expanding organizational citizenship behavior (OCB) to enhance job satisfaction and thus ensure the expected EP during the pandemic. We may consider allowing an employee to postpone work as a new managerial activity within MS.

Authors: Peethambaran Meera , Naim Mohammad Faraz
Published: September 2024

Purpose

This study explores the pivotal relationship between humble leadership (HL) and flourishing-at-work (FAW) in the context of the information technology-enabled services (ITes) industry. Specifically, it explores the mediating role of psychological empowerment (PE) and the moderating influence of proactive personality (PP) in this dynamic interplay.

Design/methodology/approach

Data from a comprehensive survey of 342 full-time employees from information technology-enabled services (ITes) organizations in India were meticulously analyzed. Utilizing covariance-based structural equation modeling (CB-SEM) in IBM AMOS 21.0.

Findings

The results illuminate the positive impact of HL on PE, subsequently enhancing FAW among employees. Furthermore, PE was identified as a partial mediator in the relationship between HL and FAW. Intriguingly, this mediation process was found to be significantly stronger when employees exhibited a higher degree of proactive personality.

Practical implications

This research underscores the critical importance of cultivating humble leadership within organizations. The findings emphasize the potential of targeted training programs aimed at nurturing humble leadership qualities among managerial staff. By doing so, organizations can significantly contribute to the emotional, psychological and social well-being of their employees, ultimately fostering a state of FAW.

Originality/value

This research innovatively links the concepts of humble leadership and FAW within the specific context of the ITes industry. By integrating PE as a mediator and PP as a moderator, this study not only fills a critical gap in existing literature but also provides a robust framework for future research.
Detecting dynamic interaction of multiple subjects in policy information communication in China
Authors: Zhou Qingqing , Guan Tianyang
Published: September 2024

Purpose

As an important part of national governance, the online communication of education policies usually attracts the attention of many subjects, including the public and the media. Existing research mainly focuses on analysing communication behaviour of a single subject. However, with the rapid development of social media, policy information communication is often accompanied by the participation of multiple subjects and forms diversified communication behaviours and interaction patterns. The comprehensive identification of multiple subjects and their interactions can accurately depict the communication process and effectively support the efficient communication of policies. Therefore, this paper aims to conduct fine-grained analysis on the multiple subjects in information communication of the education policy.

Design/methodology/approach

This paper explored the communication and interaction process of the education policy via multidimensional analysis. Specifically, the authors firstly obtained multi-source communication data to identify key communication subjects. Secondly, the authors mined the communication contents generated by communication subjects to measure the diversified correlations between subjects. Finally, the authors depicted the interaction of subjects in policy information communication.

Findings

The experimental results reveal that there are multiple key subjects in the policy information communication, and the communication roles of the subjects change with the communication process, including dominance role, one-way or two-way effect role. This further indicates the need to allocate resources dynamically in the process of policy communication.

Originality/value

Analysing the process of policy communication and identifying the dynamic interaction between communication subjects can provide more a comprehensive and detailed decision-making basis for policy formulation and implementation. In addition, the research ideas and methods presented in this paper expand the perspective of information communication research.

Authors: Tanrıverdi Mustafa , Ceran Onur , Uysal Mevlüt , Üstündağ Mutlu Tahsin
Published: September 2024

Purpose

Sustainability and accessibility of education are the main purposes of educational institutions. Higher education institutions (HEIs) have been addressing these concerns through their distance education departments for years. Especially during and after the COVID-19 pandemic, HEIs encountered challenges related to productivity, escalating costs and decreasing user satisfaction with distance education. This study proposes the integration of new and suitable information technologies (ITs) into the steps of lean management (LM) implementation. It suggests that this approach will be highly effective and beneficial, providing solutions to the problems above in higher education (HE) field. The study aims to highlight the effectiveness and benefits of incorporating new and suitable ITs into the application stages of LM principles. Sample applications in HE will be provided to enhance understanding.

Design/methodology/approach

A model is introduced for researching new ITs and incorporating appropriate ones in the application steps of LM. This model has been applied and analyzed in two case studies at Gazi University for a more comprehensive understanding.

Findings

When examining periodic surveys and usage statistics from case studies, it becomes evident that implementing LM with the support of ITs reduces waste and enhances the quality of existing work. The success observed in the case studies was notably influenced by managers’ proficiency in business processes, experience in ITs, managerial skills and support from senior management.

Practical implications

This case study provides a roadmap and step-by-step implementation of LM with IT support for HEIs. The implementation process and results will also be guiding for other sectors.

Originality/value

There is a notable absence of significant studies on integrating ITs, which have become crucial in today’s context in the stages of LM implementation. This study is envisioned as a pioneering endeavor to address this gap in the literature. Notably, challenges exist in applying LM principles outside production sectors, and limited research has been conducted. This study aims to pave the way for further research in diverse fields by conducting a comprehensive case study in the realm of HE.
Relationship between body involvement and post-trip behavioral intention in sports tourism: an embodied cognition perspective
Authors: Gao Rujiu , Koh Denise , Wang Ling
Published: September 2024

Purpose

Based on the theory of embodied cognition, this study uses the Mehrabian–Rusell model to explore the influence of tourists’ body involvement during sports vacations on their post-trip behavioral intention, as well as the regulatory role of tourism involvement in this process.

Design/methodology/approach

Structural equation modeling (SEM) was used to test the hypotheses, mediating effects and moderating effects. The data were collected through an online survey of 631 visitors to sports tourism destinations in China.

Findings

Proprioception and kinesthesia in sports tourism activities can affect post-trip behavioral intention through body arousal and tourism satisfaction. Tourism involvement positively regulates the influence of body embeddedness and body arousal on tourism satisfaction. Furthermore, a “threshold effect” exists in the emotional effect of tourists’ body involvement.

Practical implications

To develop sports tourism, it is important to take the following steps: create multi-sensory stimulation to improve the physical participation of tourists in sports tourism activities, design sports resorts that cater to people of different age groups, evaluate tourists’ satisfaction and use their feedback to make continuous improvements, improve the basic convenience services offered at sports resorts, use social media to display the unique physical environment and others characteristics of sports destinations to expand popularity.

Originality/value

This study constructs a conceptual model of the influence mechanism of tourists’ body involvement on post-trip behavioral intention to present valuable insights that could help promote the sustainable development of sports tourism.
Study on the friction loss behavior of a wire rope and liner mating pair interface under vibration conditions
Authors: Luo Zhihao , Guo Yongbo , Cao Yourui , Zhu Zheyingzi , Ma Wan , Wang Songquan , Zhang Dekun
Published: September 2024

Purpose

This study aims to study the influence of friction influencing factors between the wire rope and the liner on the safe use of the wire rope, which can provide guidance for the reliability design of the lifting system with strong dynamic response such as high speed, heavy load, etc., and improve the friction-driven stability of the system.

Design/methodology/approach

In this paper, the friction mechanism of wire rope and liner under the condition of excitation is investigated by means of wire rope-liner friction-vibration experimental platform and dynamic viscoelastic test of liner.

Findings

The results show that: With increasing excitation frequency, the friction between the three liner materials (G30, K25, PU) and the wire rope decreased, and the wear of the surface shape of the liners was greater. The dynamic thermomechanical analysis (DMA) test results showed that the viscoelasticity of the three liner materials increased when the frequency was increased.

Research limitations/implications

Wire ropes are widely used in deep shaft hoisting and building elevators. Its operational reliability depends on whether there is sufficient friction between the wire rope and the friction liner, and whether the friction liner has good wear resistance. The study of the friction between the wire rope and the liner influencing factors is of great significance for the safe service of the wire rope.

Practical implications

The related results can provide guidance for the reliability design of lifting systems with strong dynamic response, such as high speed and heavy load, to improve the friction drive stability of the system.

Originality/value

With the increase of mining depth, to improve the transportation efficiency of the hoist used in deep and ultra-deep mines, as well as to ensure the safety and reliability of its operation, it is crucial that the large friction hoisting equipment has sufficient friction between the wire rope and the friction lining, as well as whether the friction lining has a good abrasion resistance.
A novel time-varying mesh stiffness model for orthogonal face gear drives considering EHL
Authors: Zhou Wenguang , Zhu Rupeng , Lu Fengxia , Liu Wenzheng , Wang Jingjing
Published: September 2024

Purpose

This study aims to research the time-varying mesh stiffness (TVMS) model for orthogonal face gear drives considering elastohydrodynamic lubrication (EHL) and provide a theoretical basis for understanding the dynamic characteristics of face gear drives.

Design/methodology/approach

Considering EHL, a novel model is proposed to calculate the TVMS of orthogonal face gears using the deformation compatibility condition. First, the tooth surface equations of orthogonal face gears are derived according to the tooth surface generation principle. Then, the oil film thickness on the tooth surface of face gears is obtained by solving the governing equations of EHL. Furthermore, the proposed model is used to calculate the TVMS of face gears along the mesh cycle and is verified. Finally, the effects of module, tooth number of shaper cutter and pressure angle on mesh stiffness are analyzed.

Findings

The results indicate that when the contact ratio is greater than 1 and less than or equal to 2, the TVMS of face gears exhibits a phenomenon of double-single tooth alternating meshing where sudden changes occur. As the module increases, the overall mesh stiffness of face gears increases, and the magnitude of the sudden change at the moment of single-double tooth alternating meshing gradually increases. As the tooth number of shaper cutter and pressure angle increase, so does the TVMS of face gears. When the effect of oil film is considered, the calculated TVMS of face gears slightly increases overall and the increase in average oil film thickness leads to a rise in the TVMS. This study provides a theoretical basis for understanding the dynamic characteristics of face gear drives.

Originality/value

This study’s originality and value lie in its comprehensive approach, which includes conducting analysis based on loaded tooth contact, considering the influence of elastohydrodynamic lubrication, proposing a novel analytical–finite–element model, calculating TVMS of face gears, verifying the proposed model and analyzing the effects of typical structural parameters and oil film thickness.
A hybrid formation path planning based on the velocity-virtual spring method in dynamic environments
Authors: Chen Yimei , Cheng Huanhuan , Li Baoquan
Published: September 2024

Purpose

The purpose of this study is to propose a path-planning strategy based on the velocity-virtual spring method to realize collision-free tasks in dynamic environments and further improve the effect.

Design/methodology/approach

By considering factors such as the relative velocity and direction of dynamic obstacles, the repulsive force of the robot is improved, thereby enhancing the adaptability of the strategy and achieving flexible and effective avoidance against dynamic obstacles. The attraction formula has been designed to allow the robot to have better smooth changes and higher gradients near the target, helping robots better reach the target and follow formations. Moreover, to meet the demands of the various stages during the driving process, the null space behavioral control is used to solve multi-task conflict problems and strengthen formation coordination and control.

Findings

Comparison of the planning path and formation effects through simulation and physical experiments, the results of this study show that the algorithm proposed can successfully maintain formation stability and plan smooth and safe paths in static or dynamic environments.

Originality/value

This paper proposes a path-planning strategy based on the velocity-virtual spring method to plan collision-free paths for formation in dynamic environments.
Audit firm informatization and audit quality during COVID-19
Authors: Shen Hongtao , Pan Jing , Monroe Gary , You Jiaxing , Wu Huiying
Published: September 2024

Purpose

COVID-19 has forced audit firms to change the way they operate. One change has been to rely more on information technology (IT) and IT human capital to overcome COVID-19-related challenges. We refer to audit firms’ use of these two resources as audit firm informatization (AFI). It is important to understand whether AFI helps audit firms address challenges created by the pandemic. Thus, this study examines the impact of AFI on audit quality during the COVID-19 pandemic in China with a focus on IT human capital.

Design/methodology/approach

We use a mixed-methods approach. First, we perform multivariate regression analyses on archival data. Specifically, we investigate the relationship between IT human capital and audit quality and the two mechanisms (i.e. improved efficiency and reduced audit risk) underlying the relationship. We also investigate how this relationship is moderated by features of clients, audit firms and individual auditors. Then we use interviews to corroborate the results of our regression analyses.

Findings

Our analyses of archival data show that IT human capital positively affects audit quality through improved efficiency and reduced audit risk and that this positive impact is more pronounced for clients in non-manufacturing industries, those with a more opaque information environment, audit firms with greater industry coverage and individual auditors with less experience. Our interview data indicate that audit firms with more advanced AFI and a higher level of IT human capital in particular are less disrupted by the pandemic and are better able to use IT to address challenges associated with COVID-19. Furthermore, the results confirm that improved efficiency and reduced audit risk are the mechanisms through which AFI enhances audit quality. Finally, we identify issues associated with the use of IT.

Originality/value

This study is the first to investigate how IT human capital (and by extension AFI) influences audit quality in the context of the COVID-19 pandemic. Our findings should be of interest to practitioners and setters of auditing standards.

Findings

This study illuminates the introduction and adoption of Taylorist principles in early republican Turkey through multiple lenses. First, it underscores the era’s fervent drive for rapid modernization, rooted in emulation of Western models perceived as progressive. Second, using a historical narrative approach, this research highlights the pivotal role of foreign expertise in catalyzing and formalizing rationalization efforts.

Can we trust LLMs to help us? An examination of the potential use of GPT-4 in generating quality literature reviews
Authors: Zhao Min , Li Fuan , Cai Francis , Chen Haiyang , Li Zheng
Published: September 2024

Purpose

This study aims to examine the ability of Generative Pre-trained Transformer 4 (GPT-4), one of the most powerful large language models, to generate a literature review for peer-reviewed journal publications. The objective is to determine whether business scholars can rely on GPT-4’s assistance with literature reviews and how the nature of human–artificial intelligence (AI) interaction may affect the quality of the reviews generated by GPT-4.

Design/methodology/approach

A survey of 30 experienced researchers was conducted to assess the quality of the literature reviews generated by GPT-4 in comparison with a human-authored literature review published in a Social Science Citation Index (SSCI) journal. The data collected were then analyzed with analysis of variance to ascertain whether we may trust GPT-4’s assistance in writing literature reviews.

Findings

The statistical analysis reveals that when a highly structured approach being used, GPT-4 can generate a high-quality review comparable to that found in an SSCI journal publication. However, when a less structured approach is used, the generated review lacks comprehensive understating and critical analysis, and is unable to identify literature gaps for future research, although it performed well in adequate synthesis and quality writing. The findings suggest that we may trust GPT-4 to generate literature reviews that align with the publication standards of a peer-reviewed journal when using a structured approach to human–AI interaction.

Research limitations/implications

The findings suggest that we may trust GPT-4 to generate literature reviews that align with the publication standards of a peer-reviewed journal when using a structured approach to human–AI interaction. Nonetheless, cautions should be taken due to the limitations of this study discussed in the text.

Originality/value

By breaking down the specific tasks of a literature review and using a quantitative rather than qualitative assessment method, this study provides robust and more objective findings about the ability of GPT-4 to assist us with a very important research task. The findings of this study should enhance our understanding of how GPT-4 may change our research endeavor and how we may take a full advantage of the advancement in AI technology in the future research.
Listening to regulators about the challenges in regulating emerging disruptive technologies
Authors: Galhardo José Antonio Gouvêa , de Souza Cesar Alexandre
Published: September 2024

Purpose

This study aims to investigate the regulatory challenges of emerging disruptive Information and Communication Technologies (ICT) in Brazil and the strategies regulators use to address them.

Design/methodology/approach

It is an empirical qualitative research on Brazil’s three administrative levels, focusing on the legislative houses’ specialised Science and Technology Committees. It combines archival analysis of public meeting records with elite interviews of parliamentarians and technocrats who participated in Public Hearings in 2019, which results in this paper analysed through the Theory of Communicative Action with a critical stance.

Findings

The research reveals that regulatory challenges gain new dimensions by involving discussions about emerging ICT. Factors such as time constraints, rapid technological evolution and widespread adoption compound these challenges, straining the preference for the incremental pace of regulation and the traditional model of specialised regulatory agencies. The research captures some regulators’ values, underlying concerns and perceived necessities for surmounting these challenges. It also outlines the preferred process for ICT regulation, revealing parliamentary assistants and executive intermediate-level specialists as gateways for interest groups’ action.

Social implications

The study's findings highlight the crucial role of specific actors as gateways to the covert action of interest groups, particularly Big Tech firms. This contribution is significant as it empowers civil society and academia to monitor and mitigate the risk of regulatory capture, thereby promoting a more transparent and equitable regulatory environment.

Originality/value

This research is original in directly engaging with the key figures (lawmakers, legislative assistants and specialised bureaucrats) involved in the critical and timely issue of regulating emerging disruptive technologies.

Authors: Arnold Rosalyn Marie , Acton Danny , Jaydeokar Sujeet
Published: September 2024

Purpose

This study aims to investigate the demographic and clinical characteristics associated with different risk stratification levels on the Decision Support Tool for Physical Health (DST-PH). The DST-PH was designed to stratify risk of avoidable mortality in adults with intellectual disabilities.

Design/methodology/approach

A prospective cohort study design was used. Data, including age, gender, ethnicity and completed DST-PH assessments, was collected from adults with intellectual disabilities within an NHS trust in the North-West of England. Descriptive statistics and a risk factor analysis were used to investigate differences between those rating Red, Amber and Green on the DST-PH.

Findings

Risk factor analysis revealed key clinical indicators linked to avoidable mortality. Notably, those experiencing posture or mobility difficulties, transitions in care, an untreated or unstable mental health condition or significant behavioural problems were identified to be at significantly heightened risk of avoidable death. These findings emphasise the importance of proactively recognising and addressing these experiences, particularly posture- and mobility-related challenges, in individuals with intellectual disabilities. It is important to note this study’s findings are based on a small sample size. Therefore, further research with a larger and more diverse population is recommended to validate and expand upon these results.

Originality/value

To the authors’ knowledge, this is the first study which has used a risk stratification tool to investigate the clinical and demographic characteristics of individuals with intellectual disability at higher risk of avoidable mortality.
Shifting seagrass‐oyster interactions alter species response to ocean warming and acidification

A major challenge in biodiversity research is the incorporation of species interactions into frameworks describing population and community response to global edfnmental change (GEC). Mutualisms are a type of species interaction especially sensitive to changing environmental conditions, and the breakdown of facilitative species interactions could amplify the negative impacts of novel climate regimes on focal species.

Here, we investigate how reciprocal interactions between two coastal foundation species, the eastern oyster (Crassostrea virginica) and eelgrass (Zostera marina) shift in sign and magnitude in response to ocean warming (+1.5°C) and acidification (−0.4 pH) via a manipulative co‐culture experiment in mesocosms.

Under ambient environmental conditions, oysters facilitated eelgrass leaf growth and clonal reproduction by 35% and 38%, respectively. Simultaneously, eelgrass decreased the oyster condition index (the ratio of tissue to shell biomass) by 35%, indicating greater allocation of energy to shell growth instead of soft tissues at ambient conditions. Varying sensitivities of each species to ocean warming and/or acidification treatments led to complex shifts in species interactions that were trait dependent. As such, community outcomes under future conditions were influenced by species interactions that amplified and mitigated species response to environmental change.

Synthesis: Given that species interaction effect sizes were similar in magnitude to effect sizes of warming or pH treatments, our results underscore the need to identify key species and interaction types that strongly influence community response to GEC. Specifically, for macrophyte‐bivalve interactions, understanding how physiological limitations on growth are impacted by environmental heterogeneity and co‐culture will support the successful restoration of natural populations and the rapid expansion of aquaculture.
A micro‐level model for crisis management in tourism destinations: An interdisciplinary approach
Authors: Khardani Christin , Schmude Jürgen
Published: September 2024

Crisis management models aim to prevent, prepare and successfully overcome a crisis. The tourism industry is particularly prone to crises and thus requires adequate models to deal with crises and disasters. Several researchers developed crisis management models for tourism crises. As scholars call for a more holistic approach, this systematic literature review examines 25 crisis management models with organisational and tourism focus between 1979 and 2019 applicable to the tourism field. A textual narrative synthesis is used as methodological approach to analyse and understand the identified models, not only formally but also content‐wise. The findings show that crisis terminology is not consistent, that the crisis lifecycle and crisis management processes are used disparately and that stakeholder involvement within the models is low. As a result, a new model for destination crisis management is created on a micro‐level with aligned terms and phases.
Why governments want to learn about citizens' preferences. Explaining the representational logic behind government polling

While it is generally admitted that governments in most democracies make extensive use of public opinion research, we do not know much about the way they mobilize this resource. When and why do they want to learn about public opinion? What determines differences in the intensity of government polling over the electoral cycle? Are government opinion polls primarily a tool for testing the reception of government proposals or for learning more about issues that are important to citizens? And what does this tell us about the way political representation works? Understanding governments as actors in the production of public opinion, not just as passive consumers, our focus is on polls commissioned directly by governments. We argue that government polls can help us to better understand how contemporary political representation works since they can play an important role as ‘update instrument’ in anticipatory representation or as a decision‐making aid in promissory representation. By studying government polls as dependent variable, we develop an innovative research design and systematically analyse the factors that explain whether the intensity of government polling (the number of questions asked) varies across different stages of the electoral cycle and whether the issues they ask about correspond more to the government's priorities or those of the public. We present evidence from Germany, mobilizing an original database of all survey questions directly commissioned by the German government during the 18th and 19th legislative periods (2013–2021). Our findings help to better understand the factors that determine the intensity of government polling at different moments of the electoral cycle and to identify the different logic of representation behind this activity. The transition from the post‐election period to the routine period and from the routine period to the pre‐election period correspond to turning points in the German government's use of this instrument. While we could not observe any direct effects of the electoral cycle on the intensity of government polling, the interplay between the former and different types of policy issues proves to be insightful. The government commissions significantly more survey questions on government priorities during the first 3 months in office than during routine times and significantly more survey questions on salient issues as federal elections approach. Moreover, we show that governments commission fewer questions on issues they ‘own’, which points in the same direction as previous studies showing that governments are less interested in public opinion on these issues.
Who (actually) gets the farm? Intergenerational farm succession in the United States
Authors: Haws Adrian , Just David R. , Price Joseph
Published: September 2024

Farm succession is a central issue in agricultural policy. Yet although many studies explore succession planning, little is known about how farms are actually transferred. We provide the first population‐level evidence on intergenerational farm succession by linking US census records for millions of farmers' children in 1900 and 1910 to identify which children own and operate the family farm up to 40 years later. We first show that daughters are rarely successors. Using a within‐family identification strategy, we find that first‐born sons are slightly more likely than their younger brothers to be successors while their parents are working aged. However, birth order is not predictive of who receives the farm when parents are older or deceased. For later farm transfers, sons who were previously tenant farmers are much more likely than their brothers to be successors, possibly because they are better prepared. Fewer than one‐fifth of farmers transfer their farm to any son. Our study relies on rich historical data because current policy prevents the necessary data linkages for studying intergenerational farm succession. Providing a secure system for researchers to link modern agricultural data to population microdata, similar to what has been achieved with other data sources, would yield crucial insights into long‐term agricultural policy issues in the US.
