This qualitative study examines barriers to implementing gender equality laws in rural Ghana that
occur despite progressive constitutional provisions. Drawing on in-depth interviews with 15 experts from
NGOs, government, and academia, the analysis applies Margaret Archer’s morphogenetic theory of
structure, culture, and agency. Structural barriers include institutional underfunding and weak enforcement
mechanisms. Cultural conditioning manifests in entrenched norms such ...

During magnetospheric perturbations a relatively thin current sheet with thickness about several
proton gyroradii forms in the Earth’s magnetotail. In a framework of the kinetic model describing current
sheet thinning in the magnetotail, the processes of its formation are investigated depending on the normal
magnetic field magnitude which affects both the current sheet structure and particle dynamics within ...

The influence of asymmetry of plasma sources on the structure and spatial localization of a superthin
current sheet (STCS) supported by demagnetized electrons is studied using a self-consistent model. The
simulation takes into account the presence of a single plasma source in the northern hemisphere, which
makes the plasma flow asymmetric. It is demonstrated that the asymmetry of ...

This paper investigates stock underpricing in the Russian capital market during initial public offerings in the present-day situation. The econometric study of initial public offerings in the Russian market for 2006–2024 shows that such factors as dividend policy, technological profile of the company, and the difference between the actual and expected offering price in crease ...

Illegal, unreported, and unregulated (IUU) fishing driven by artisanal small-scale fisheries is a critical threat to global biodiversity and is exemplified by the commercial extinction of Caspian sturgeons (Acipenser and Huso). A key knowledge gap persists regarding the scale and behavioral dynamics of these operations.We tested the hypothesis that persistent high-volume sturgeon poaching is sustained ...

Every discrete dynamical system (cascade) generated by a homeomorphism induces a continuous
dynamic system (flow) — a suspension. However, not every flow is equivalent to a suspension
over a cascade, a necessary and sufficient condition for this is the existence of a global
section for the flow. In the case of the existence, the flow is equivalent to ...

The results of the conducted study demonstrate the effect that contemporary economic sanctions have on the development of the International North-South Transport Corridor, a proposed infrastructure initiative that connects India, Iran, Russia, and other Eurasian nations. Infrastructural projects have been delayed, investment flows have been severely restricted, and the institutional consolidation of the corridor has ...

This study explores the intersection of culture, ESG disclosures, and financial performance in the banking sector, drawing on cultural relativism and ethical universalism. Analyzing ESG data from 52 European and 52 Asian banks between 2010 and 2020, we assess how the content of ESG disclosures influences financial performance, accounting for cultural differences. Using a robust ...

Using data from Chinese A-share listed companies from 2007 to 2024, this study examines the market response to corporate digital technology risk disclosure, with a focus on institutional investor holdings. The results show that digital technology risk disclosure increases institutional investor holdings, lending support to the convergence hypothesis of risk disclosure. And this is primarily ...

We revise the notion of the blobbed topological recursion by extending it to the setting of generalized topological recursion as well as allowing blobs which do not necessarily admit topological expansion. We show that the so-called non-perturbative differentials form a special case of this revisited version of blobbed topological recursion. Furthermore, we prove the KP ...

Weight systems associated to the Lie algebras 𝔤𝔩(N) for N = 1,2,... can be unified into auniversal one. The construction is based on an extension of the 𝔤𝔩(N) weight systems to permutations. This universal weight system takes values in the algebra of polynomials C[N;C1,C2,...] in infinitely many variables. We show that under the substitution Cm ...

The changing political mood of Russians is a constant subject of interest for sociological agencies. With the development of the Internet, conventional questionnaire research began to be supplemented by online surveys and, despite some skepticism, by social media mining. This article attempts to adjust an accidental web-sample so as to bring its estimates closer to ...

We deal with the global in time weak solutions to the 1D compressible Navier-Stokes system of equations for large discontinuous initial data and nonhomogeneous boundary conditions of three standard types. We prove the Lipschitz-type continuous dependence of the solution $(\eta,u,\theta)$, in a norm slightly stronger than $L^{2,\infty}(Q)\times L^2(Q)\times L^2(Q)$, on the initial data $(\eta^0,u^0,e^0)$ in a ...

This paper proposes Covariate-Balanced Weighted Stacked Difference-in-Differences (CBWSDID), a design-based extension of weighted stacked DID for settings in which untreated trends may be conditionally rather than unconditionally parallel. The estimator separates within-subexperiment design adjustment from across-subexperiment aggregation: matching or weighting improves treated-control comparability within each stacked subexperiment, while the corrective stacked weights of Wing et ...

We investigate the interplay between the dimension of the space of static potentials and the geometric and topological structure of the underlying static three-manifold. A partial classification of boundaryless static manifolds is obtained in terms of this dimension. We also treat the case of static manifolds with boundary. In particular, we prove that if a ...

Label prediction in neural networks (NNs) has O(n) complexity proportional to the number of classes. This holds true for classification using fully connected layers and cosine similarity with some set of class prototypes. In this paper we show that if NN latent space (LS) geometry is known and possesses specific properties, label prediction complexity can ...
