Building a Potemkin village in occupied China: Japan's wartime system of linked trade, 1939–43

open access: yesThe Economic History Review, EarlyView.
Abstract The paper discusses the novel but little‐known exchange rate system of Japanese‐occupied North China during the Second Sino‐Japanese War, in which exporters were given the right to import in the form of a piece of yellow paper, which could be sold in the secondary market.

A Comparative Review of Specification Tests for Diffusion Models

open access: yesInternational Statistical Review, EarlyView.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

The Role of Dice in the Emergence of the Probability Calculus

open access: yesInternational Statistical Review, EarlyView.
Summary The early development of the probability calculus was clearly influenced by the roll of dice. However, while dice have been cast since time immemorial, documented calculations on the frequency of various dice throws date back only to the mid‐13th century.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Laws and Reasons Why

open access: yesAnalytic Philosophy, EarlyView.
ABSTRACT Laws play some role in explanations: at the very least, they somehow connect what is explained, or the explanandum, to what explains, or the explanans. Thus, thermodynamical laws connect the match's being struck and its lightning, so that the former causes the latter; and laws about set formation connect Socrates' existence with {Socrates}'s ...

Navigating the Path to Mathematics Success: Exploring Academic Performance and Exclusionary School Discipline Among Black Students

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study examines the predictive relationships among early mathematics and reading achievement, school discipline, and later mathematics performance for Black students. Using path analysis, we analyze a cohort of 36,668 Black students in Texas public schools from fourth to seventh grade.

Hybrid Symbolic-Numeric Computing in Linear and Polynomial Algebra [PDF]

open access: yes, 2020
In this thesis, we introduce hybrid symbolic-numeric methods for solving problems in linear and polynomial algebra. We mainly address the approximate GCD problem for polynomials, and problems related to parametric and polynomial matrices. For symbolic methods, our main concern is their complexity and for the numerical methods we are more concerned ...
