The Political Economy of Attention: Media Salience, Voter Cognition, and Electoral Accountability

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT We review conceptual and empirical contributions to the political economy of attention, with a focus on how attention allocation shapes political behavior and electoral accountability. The review distinguishes between endogenous (goal‐directed) and exogenous (stimulus‐driven) attention and examines how these concepts are incorporated into ...

The fundamental theorem of asset pricing with and without transaction costs

open access: yesMathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.
Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...

Curvatures of the Melnikov type, Hausdorff dimension, rectifiability, and singular integrals on R-n [PDF]

open access: yes, 2000
One of the most fundamental steps leading to the solution of the analytic capacity problem ( for 1-sets) was the discovery by Melnikov of an identity relating the sum of permutations of products of the Cauchy kernel to the three-point Menger curvature ...

Digital Roots or Digital Routes? Broadband Expansion and the Rural‐Urban Migration in China

open access: yesPopulation and Development Review, EarlyView.
Abstract This study investigates how broadband internet affects rural–urban migration in China using the Universal Broadband and Telecommunication Services pilot program launched in 2015 as a quasi‐experimental setting. Analyzing China Household Finance Survey data (2013–2021) with difference‐in‐differences estimation, we find that improved internet ...

Hyperbolic Kac-Moody Algebra from Intersecting p-branes [PDF]

open access: yes, 1999
A subclass of recently discovered class of solutions in multidimensional gravity with intersecting p-branes related to Lie algebras and governed by a set of harmonic functions is considered. This subclass in case of three Euclidean p-branes (one electric

Open‐Source Tools for Building Data‐Driven, Sovereignty‐Permitting Web Apps

open access: yesJournal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.
Public domain or access‐controlled web apps provide a simple and relatively cheap way to increase the accessibility of information within data resources. Modern data environments, especially those subject to Māori Data Sovereignty (MDSov) constraints, face technical challenges balancing data security and privacy with accessibility and collective ...

Composite electric S-brane solutions with maximal number of branes

open access: yes, 2004
In this paper we consider (n+1)-dimensional cosmological model with scalar field and antisymmetric (p+2)-form. Using an electric composite Sp-brane ansatz the field equations for the original system reduce to the equations for a Toda-like system with n(n-

Composite fluxbranes with general intersections [PDF]

open access: yes, 2002
Generalized composite fluxbrane solutions for a wide class of intersection rules are obtained. The solutions are defined on a manifold which contains a product of n Ricci-flat spaces M_1 x ... x M_n with 1-dimensional M_1. They are defined up to a set of

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Prediction of chaos in a Josephson junction by the Melnikov-function technique [PDF]

open access: yesPhysical Review B, 1986
The Melnikov function for prediction of Smale horseshoe chaos is applied to the rf-driven Josephson junction. Linear and quadratic damping resistors are considered. In the latter case the analytic solution including damping and dc bias is used to obtain an improved threshold curve for the onset of chaos.
