A fast metaheuristic approach for the planar multiple obnoxious facility location problem

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The multiple obnoxious facility location problem is one of the most studied problems in the literature of the obnoxious facility location problems family. In this work, we propose an alternative algorithmic approach for this problem, based on an efficient metaheuristic procedure over a discretization of the plane based on Voronoi diagrams ...

Reliability of Three Image‐Based Instrumental Color‐Measurement Methods

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To compare the precision of three clinically applicable, image‐based color assessment methods—smartphone imaging, a clinical colorimeter (Optishade), and a digital scanning device (Borea Cobra)—against a benchtop spectrophotometer for measuring CIELAB coordinates and CIEDE2000 (ΔE00) color differences of composite resin shades ...

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

A geography of access to justice: mapping social welfare legal aid need and provision in England and Wales

open access: yesJournal of Law and Society, EarlyView.
Abstract Our research combined statistical data, interviews, and geographic information system (GIS) tools to map social welfare legal aid ‘deserts’ in England and Wales. This novel mixed methodology enabled us to explore the spatiality of unmet legal aid need.

Density‐Valued ARMA Models by Spline Mixtures

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This paper proposes a novel framework for modeling time series of probability density functions by extending autoregressive moving average (ARMA) models to density‐valued data. The method is based on a transformation approach, wherein each density function on a compact domain [0,1]d$$ {\left[0,1\right]}^d $$ is approximated by a B‐spline ...

The Mathematical History Behind the Granger–Johansen Representation Theorem

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT When can a vector time series that is integrated once (i.e., becomes stationary after taking first differences) be described in error correction form? The answer to this is provided by the Granger–Johansen representation theorem. From a mathematical point of view, the theorem can be viewed as essentially a statement concerning the geometry of ...

Least Trimmed Squares: Cointegration and Outliers

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT When applying the cointegrated autoregressive distributed lag model it is common to include indicator variables for outliers. This is often done in a somewhat ad hoc way. Least Trimmed Squares estimation provides a more systematic approach. This estimator is robust to a large number of outliers of many types.

Beyond Substitution—An Antipositionalist's Guide to Subtraction—

open access: yesPhilosophy and Phenomenological Research, EarlyView.
ABSTRACT Existing accounts of relations do not properly account for variably polyadic relations: they fail to capture the relationship between completions of the same relation by different numbers of relata. This paper develops a fully general account of such relations by adding an operation of subtraction to the antipositionalist theory of relations ...

A Natural Language Processing Approach to Identifying Partisan Framing of Climate Change Denialism, Fatalism, and Solutions in US Congressional Speeches

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...

Reading Dürer in Late Sixteenth‐Century Padua: Matteo Macigni (ca. 1510–1582), His Library and the Annotated Institutionum geometricarum (Paris, 1535)

open access: yesRenaissance Studies, EarlyView.
ABSTRACT This article contributes to the history of material culture and intellectual biography by definitively identifying the Paduan scholar Matteo Macigni (ca. 1510–1582) as the author of the annotations found in a 1535 copy of Albrecht Dürer’s Institutionum geometricarum currently preserved in Vicenza.
