Shaping circular disclosure capital? Intellectual capital and DEI disclosure maturity in SMEs

Purpose This study aims to examine how the human, structural and relational dimensions of Circular Intellectual Capital (CIC) contribute to the development of Circular Disclosure Capital (CDC), conceptualized as a domain-specific organizational disclosure capability enabling firm...

Supplier's origin and customer perceived value in inter-organizational relationships: the case of the Tunisian retailing sector

Purpose The aim of this article is to empirically study the relationship between supplier origin (SO) and key retailers’ perceived value (RPV) in their collaborative relationships with local suppliers, taking cultural dynamics into account. This theoretical question is examined f...

Accelerated Alternating Minimization Algorithm for Low‐Rank Approximations in the Chebyshev Norm

ABSTRACT Nowadays, low‐rank approximations of matrices are an important component of many methods in science and engineering. Traditionally, low‐rank approximations are considered in unitarily invariant norms; however, recently element‐wise approximations have also received signi...

Effects of Cocultivation of Lichenophilic Yeasts with Bacteria Escherichia coli and Staphylococcus aureus

Abstract— Lichens are complex systems, and the taxonomic structure of their microbial communities follows a number of patterns. Similar to bacteria, yeasts are integral components of the lichen symbioses. Their role in lichens is, however, presently unknown. Existence and nature...

Choosing Between AI Responses: How Valence, Arousal, and Dominance Shape User Preference

This study examines how emotional tone shapes user preference in human–large language model (LLM) interaction. Drawing on the Computers as Social Actors framework, we treat conversational AI as a social communicator whose affective cues influence user judgments. Using large-scale...

Pericyte-derived cancer-associated fibroblasts correlate with poor survival and are enriched after chemoradiotherapy in glioblastoma

The role of cancer-associated fibroblasts (CAFs) in glioblastoma remains unclear, as their existence in the brain tumor microenvironment is still debated, given that the normal brain parenchyma is devoid of fibroblasts. It is unclear whether cells described as CAFs represent a di...

From FAT to value: building competence through fairness, accountability and transparency for sustainable business

Purpose The aim of this paper is to investigate how core characteristics of artificial intelligence (AI), including fairness, accountability and transparency (FAT), contribute to sustainable business value creation. Design/methodology/approach The data were collected through a su...

Effect of Structural Motif on Magnetic Properties in Molybdenum Chlorides of Mo5+ Ions: Ferromagnetism from Mo2Cl10 Dimers and Antiferromagnetism from Isolated MoCl6– Anions

Abstract The evolution of magnetic properties in molybdenum chloride systems caused by structural motif changes was investigated by magnetic property measurements and DFT calculations. In ξ-MoCl5, characterized by the presence of molybdenum dimers, the formation of ferromagnetic...

Predicting the continuity of international scientific collaboration in the BRICS: a machine learning approach

Purpose This study aims to predict respondent-reported continuity of international scientific collaboration within the BRICS through a supervised binary classification approach. It examines whether respondents reported that collaborations continued in the form of joint projects a...

Oil Revenue Absorption and Macroeconomic Vulnerability: Evidence from a DSGE Model of a Small Open Oil-Exporting Economy

Oil-exporting economies are notoriously sensitive to external shocks, but the importance of current oil revenue absorption for macroeconomic shock transmission has not been explored thoroughly. This paper constructs a stylized DSGE model to analyze how macroeconomic shock propaga...

Infinite-dimensional nonlinear stationary Fokker–Planck–Kolmogorov equations

Abstract We prove existence of a probability solution to the nonlinear stationary Fokker–Planck–Kolmogorov equation on an infinite dimensional space with a centered Gaussian measure γ with a unit diffusion operator and a drift of the form − x + v ( p , x ), where v is a bounded m...

Stress tensor of inhomogeneous flexible polymer chain solutions beyond the ground-state dominance approximation

We derive the stress tensor of a flexible polymer solution within the Gaussian-chain self-consistent field theory (SCFT) without invoking the ground-state dominance (GSD) approximation. Starting from a covariant formulation of the single-chain partition function in a background m...

Political polarisation and democratic backsliding: Moldova’s Paradox

Moldova has been prone to socio-political polarisation due to historical, ethno-linguistic, and geopolitical factors. However, portraying modern Moldova as being torn between the West and the East oversimplifies the case. In Moldova, socio-political polarisation is indeed on the...

Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

Negative Spectrum of Non-local Operators with Periodic Potential

The paper deals with spectral analysis of non-local operators arising in population dynamics models. We consider negative periodic perturbations of non-local operators of the convolution type. Such operators describe evolutions of the first correlation function in the stochastic...

HF Heating Effects as Seen From Below and Above: First Results of Joint SURA–Ionosfera‐M Experiment

Abstract This paper presents the first results of a coordinated experiment on the ionospheric plasma response to high‐frequency (HF) overdense heating, conducted using the SURA heating facility and the Ionosfera‐M satellite. The experiment combined ground‐based observations with...

Founder Narcissistic Admiration and Young Firm Performance: The Mediating Role of Innovative Ambidexterity

Abstract Personality characteristics of entrepreneurial leaders appear to play an important role in facilitating the kinds of innovative activities that enhance young firm performance. Scholars have highlighted the need for these firms to demonstrate innovative ambidexterity, or...

Peptide language pragmatic analysis and two-stage hierarchical learning framework for therapeutic peptide prediction

Therapeutic peptides exert pivotal effects in diverse biological processes, and have attracted significant interest in the field of biomedicine in recent years. However, most existing methods often fail to adequately capture the intricate interactions among amino acid residues an...

Generative geospatial modelling with geometric algebra

Abstract The integration of data-driven and knowledge-driven approaches in generative geospatial modelling (GGM) is often hindered by their mathematical incompatibilities. Here, we propose a geometric algebra (GA)-based framework that employs a unified multi-vector representation...

Fiscal and Structural Drivers of Regional Investments Divergence: Evidence from Kazakhstan and European Benchmark Economies

This study investigates whether the interaction between structural characteristics and fiscal mechanisms determines regional investment allocation and contributes to regional divergence in Kazakhstan. To achieve this aim, panel regression with interaction effects and cross-countr...
