Published: December 2024

ABSTRACTTuberculosis (TB), caused byMycobacterium tuberculosis(Mtb), remains a global health challenge, characterized by significant heterogeneity in its clinical presentation and physiopathology, underscoring the need for optimized models to better understand host-pathogen interactions. This study evaluated the impact of both host and Mtb clinical isolate variability on bacterial growth and dormancy and immune responses using anin vitrogranuloma model. Peripheral blood mononuclear cells from active TB patients were infected with autologous and heterologous Mtb clinical isolates, as well as the H37Rv Mtb reference strain. Bacterial growth and dormancy dynamics and cytokines release were assessed at 0-, 7-, 14- and 21-days post-infection. Results revealed that bacterial growth and dormancy dynamics were mostly isolate-dependent, with almost no impact of PBMC donor. However, at 7-days post-infection, autologous infections exhibited lower bacterial loads and elevated Th1-type cytokines, such as TNF-α and IFN-γ. Yet, this early advantage in bacterial control did not persist at later time points. These findings highlight the importance of host-pathogen pairing in shaping immune responses and validate thein vitrogranuloma model as a relevant tool for studying TB pathogenesis and evaluating therapeutic interventions. Furthermore, further research is needed to decipher the specificities of autologous immune response.

By tuning the superconducting order parameter with an applied magnetic field, we use neutron diffraction to compare the magnetically ordered phases in superconducting and normal states of CeCo0.5Rh0.5In5. At zero applied field, CeCo0.5Rh0.5In5 displays both superconductivity (Tc=1.3K) and spatially long-ranged commensurate ↑↓↑↓ antiferromagnetism [TN=2.5K, propagation vector Q⃗=(12,12,12)]. Neutron spectroscopy fails to measure propagating magnetic excitations from this ground state with only temporally overdamped fluctuations observable. On applying a magnetic field which suppresses superconductivity, we find anisotropic behavior in the static magnetism. When the applied magnetic field is along the crystallographic c axis, no change in the static magnetic response is observable. However, when the field is oriented within the a−b plane, an increase in TN and change in the critical response are measured. At low temperatures in the superconducting phase, the elastic magnetic intensity increases linearly (∝|H|) with small a−b oriented fields. However, this trend is interrupted at intermediate fields where commensurate block ↑↑↓↓ magnetism with propagation vector Q⃗=(12,12,14) forms. For large applied fields in the [11¯0] direction which completely suppresses superconductivity, weakly incommensurate magnetic order along L is observed to replace the commensurate response present in the superconducting and vortex phases. We discuss experimental considerations related to this shift in momentum and suggest field-induced incommensurate static magnetism, present in the normal state of superconducting and antiferromagnetic CeCo0.5Rh0.5In5 for a−b plane oriented magnetic fields. We speculate that these field-dependent properties are tied to the field-induced anisotropy associated with the local Ce3+ crystal field environment of the tetragonal “115” structure.

Single isolated photon production in the
NLO*
approximation of the parton Reggeization approach
Authors: Chernyshev A. A. , Saleev V. A. 
Published: December 2024

The hadroproduction of single isolated photon at high energies is studied within the framework of the next-to-leading order (NLO⋆) approximation of the parton Reggeization approach based on the modified multi-Regge limit of the hard scattering quantum chromodynamics (QCD) amplitudes. The contribution from the LO subprocess QQ¯→γ and the NLO tree-level corrections QR→γq and QQ¯→γg are considered. To avoid specific double counting in rapidity between tree-level corrections to the hard scattering coefficient and unintegrated PDFs, a corresponding subtraction scheme is proposed. We demonstrated self-consistency of the parton Reggeization approach using the subtraction scheme. The results of calculations are compared with data from various collaborations in the wide energy range S=24  GeV–13  TeV. We obtained a quite satisfactory agreement with data up to pTγ/S≃0.2–0.3. Predictions for the future SPD NICA experiment were discussed.

New nonrenormalization theorem from UV/IR mixing
Authors: Abel Steven , Dienes Keith R. , Nutricati Luca A. 
Published: December 2024

In this paper, we prove a new nonrenormalization theorem which arises from UV/IR mixing. This theorem and its corollaries are relevant for all four-dimensional perturbative tachyon-free closed string theories which can be realized from higher-dimensional theories via geometric compactifications. As such, our theorem therefore holds regardless of the presence or absence of spacetime supersymmetry and regardless of the gauge symmetries or matter content involved. This theorem resolves a hidden clash between modular invariance and the process of decompactification, and enables us to uncover a number of surprising phenomenological properties of these theories. Chief among these is the fact that certain physical quantities within such theories cannot exhibit logarithmic or power-law running and instead enter an effective fixed-point regime above the compactification scale. This cessation of running occurs as the result of the UV/IR mixing inherent in the theory. These effects apply not only for gauge couplings but also for the Higgs mass and other quantities of phenomenological interest, thereby eliminating the logarithmic and/or power-law running that might have otherwise appeared for such quantities. These results illustrate the power of UV/IR mixing to tame divergences—even without supersymmetry—and reinforce the notion that UV/IR mixing may play a vital role in resolving hierarchy problems without supersymmetry.

Published: December 2024

Purpose
This research explores wine customer interaction with connected packaging in retail, offering insights for wine producers to enhance customer behavioural engagement strategies. The study aims to understand patterns of customer visual attention and information preferences in the context of connected packaging.

Design/methodology/approach
The research adopts an empirics-first (EF) approach, including a two-study mixed-method research design. EF is particularly suited to exploring emerging customer behaviours in innovative technological contexts. Study One uses Google Analytics and Tag Manager to measure connected packaging users’ visual attention and behavioural engagement. Study Two uses maximum difference scaling to assess user preferences for wine attributes in retail.

Findings
Study One reveals distinct patterns of user behavioural engagement. Highly engaged users exhibit deeper interaction with product, brand and sustainability information, often revisiting content. First-time users focus on top-of-page content before disengaging. Study Two results corroborate the importance of product information (grape variety, wine style and region of origin), with highly involved wine consumers showing greater interest in connected packaging.

Originality/value
This research advances the understanding of connected packaging user interaction and information preferences, an area previously underexplored. It demonstrates the potential of connected packaging for enhancing ongoing customer behavioural engagement and providing additional product information. The study’s innovative EF approach, combining real-world behavioural data with preference analysis, supports and extends existing research on wine attribute preferences while demonstrating the potential of connected packaging as an ongoing value co-creation tool.
A path analysis study of relationships between long work hours, stress, burnout, job satisfaction and turnover intention among mine workers
Authors: Smith Todd D. , Mullins-Jaime Charmaine , Balogun Abdulrazak O. 
Published: December 2024

PurposeIncreased work hours can result in stress and burnout among mine workers. Research within stone, sand and gravel mining operations is limited and has not explored whether health impairment, in this context, influences job satisfaction and turnover intention among these workers.Design/methodology/approachA path analysis was completed using Mplus to assess a theoretical model and hypotheses associated with model variables to include work hours, stress, burnout, job satisfaction and turnover intention. Cross-sectional survey data from 419 stone, sand and gravel mine workers were used in the path analysis.FindingsModel fit was good. Work hours were positively associated with stress, stress was positively associated with burnout, stress and burnout were negatively associated with job satisfaction, stress and burnout were positively associated with turnover intention and job satisfaction was negatively associated with turnover intention. Burnout partially mediated the relationship between stress and both job satisfaction and turnover intention. Job satisfaction partially mediated the relationship between stress and turnover intention and burnout and turnover intention. An alternate model determined there was no direct relationship between work hours and burnout and that this relationship was fully mediated by stress.Originality/valueFindings illustrate the importance of managing work hours among mine workers to reduce health impairment and to bolster job satisfaction and reduce turnover intention.
Rating of crop price insurance in China with evidence from corn
Authors: Ye Minghua , Chen Kang , Wang Tongjiang , Zhu Junsheng 
Published: December 2024

PurposeCrop price insurance can reduce losses from price volatility for crop producers, but pricing is one paramount important issue. The objective of this research is to provide a tentative method for pricing of crop price insurance with data from the futures market.Design/methodology/approachWith weekly settlement price of January corn futures from the second week of January 2009 to the fourth week of April 2020 in China, we assume that corn futures price follows fractional Brownian motion, and apply an improved Black model.FindingsOur results reveal that the proposed model can be used to yield a fair premium and crop price insurance with varying insured prices and gradient coverage ratios can be used to meet the divergent needs of farmers at an affordable cost for price risk management purposes.Research limitations/implicationsResults can be fine-tuned by extending research to crops such as wheat and rice, and by modeling price volatility with data from options market.Originality/valueThis study offers one plausible way to rate crop price insurance using data from the futures market, and thus adds to this thread of literature by incorporating fractional Brownian motion into an improved Black model.
Role of corporate innovation and uncertainty in determining corporate investment of the firm: does financial constraint, executive risk preference and firm risk-taking ability play any role
Authors: Rana Anamika , Debata Byomakesh 
Published: December 2024

Purpose
This paper aims to investigate the relationship between corporate innovation and the firm’s corporate investment. Further, the authors begin with the assertion that the relationship between corporate innovation and corporate investment is impacted by significantly a) uncertain periods, b) financial constraint, c) executives’ risk preference and d) firm risk-taking ability.

Design/methodology/approach
This study has considered non-financial listed companies (774 firms) for the period spanning from 2010–2022. The authors use a fixed effect regression model within a panel data framework to examine the relationship between corporate innovation and investment. For robustness, the authors use system generalised methods of moments to investigate the relationship between corporate investment and corporate innovation across all the samples.

Findings
This study finds a positive relationship between corporate innovation and corporate investment, which means when the firm tries to make some innovation, it will increase its expenditure on fixed assets. However, the positive relationship between corporate innovation and corporate investment reduces with uncertainty. Additionally, financial constraint plays a significant role in determining this relationship. Executives and firms with high risk-taking ability tend to be more inclined to make investments.

Originality/value
The study is unique because it determines the impact of corporate innovation on corporate investment. The current literature is focused on corporate innovation and uncertainties. However, no light has been shed on the relationship between corporate innovation and investment. At the same time, the authors have introduced three more variables which play a significant role in determining the corporate innovation-investment relationship.
Why should I trust you? Influence of explanation design on consumer behavior in AI-based services
Authors: Nizette Florence , Hammedi Wafa , van Riel Allard C.R. , Steils Nadia 
Published: December 2024

PurposeThis study explores how the format of explanations used in artificial intelligence (AI)-based services affects consumer behavior, specifically the effects of explanation detail (low vs high) and consumer control (automatic vs on demand) on trust and acceptance. The aim is to provide service providers with insights into how to optimize the format of explanations to enhance consumer evaluations of AI-based services.Design/methodology/approachDrawing on the literature on explainable AI (XAI) and information overload theory, a conceptual model is developed. To empirically test the conceptual model, two between-subjects experiments were conducted wherein the level of detail and level of control were manipulated, taking AI-based recommendations as a use case. The data were analyzed via partial least squares (PLS) regressions.FindingsThe results reveal significant positive correlations between level of detail and perceived understanding and between level of detail and perceived assurance. The level of control negatively moderates the relationship between the level of detail and perceived understanding. Further analyses revealed that the perceived competence and perceived integrity of AI systems positively and significantly influence the acceptance and purchase intentions of AI-based services.Practical implicationsThis research offers service providers key insights into how tailored explanations and maintaining a balance between detail and control build consumer trust and enhance AI-based service outcomes.Originality/valueThis article elucidates the nuanced interplay between the level of detail and control over explanations for non-expert consumers in high-credence service sectors. The findings offer insights into the design of more consumer-centric explanations to increase the acceptance of AI-based services.
