Revisiting International Student Mobility Under New Geopolitics: Stratification, Conditionality, and Uncertainty

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT In the 21st century, the governance of international student mobility has undergone a fundamental transformation, driven primarily by securitization, geoeconomic competition, and domestic political pressures that conventional market‐based frameworks such as the push‐pull model and human capital theory cannot adequately explain.

Higher Dimensional Adeles, Mean-Periodicity and Zeta Functions of Arithmetic Surfaces

open access: yes, 2014
This thesis is concerned with the analytic properties of arithmetic zeta functions, which remain largely conjectural at the time of writing. We will focus primarily on the most basic amongst them - meromorphic continuation and functional equation.

Two Two‐Tier Stochastic Frontier Replications

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

open access: yesThe Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Sulla trattazione assiomatica delle medie

open access: yes, 1992
We consider some axiomatic treatments for the arithmetic mean, the quasi-arithmetic mean, the quasi-linear mean, the Φ-mean, the general mean and the (α,Φ)-mean.

Experimental and Numerical Assessment of Progressive Damage in CF/PEEK Laminates Under Monotonic and Progressive Cyclic Four‐Point Bending

open access: yesPolymer Composites, EarlyView.
Experimental four‐point bending of CF/PEEK laminates under monotonic and progressive cyclic loading is assessed using classical lamination theory and a calibrated Hashin progressive damage model. ABSTRACT Carbon‐fiber‐reinforced PEEK composites combine high specific strength, corrosion resistance, and damage tolerance, supporting their use in aerospace,
