We present a social network and forensic analysis of the vote counts of Spanish national elections that took place in December 2015 and their sequel in June 2016. We initially consider the phenomenon of bipartisanship breakdown by analyzing spatial distributions of several bipartisanship indices. We find that such breakdown is more prominently close to cosmopolite and largely populated areas and less important in rural areas where bipartisanship still prevails, and its evolution mildly… 

A spatial analysis of parliamentary elections in Sweden 1985–2018

TLDR
The cultural field hypothesis is tested on Sweden by studying the middle-long-term evolution of the spatial structure of political choice over the last three decades and it is shown that spatial correlations decay logarithmically, which is a sign of long-ranged interactions, and that Sweden can be divided into three or four large and stable politico-cultural communities.

Multipolar social systems: Measuring polarization beyond dichotomous contexts

Social polarization is a growing concern worldwide, as it strains social relations, erodes trust in institutions, and thus threatens democratic societies. Academic efforts to understand this

Newcomb–Benford law and the detection of frauds in international trade

TLDR
The features of the traders for which the Newcomb–Benford law should hold in the absence of fraudulent data manipulation are shown, in the context of a European Union market, to shed light on a relevant and debated question.

Analyzing Benford’s Law’s Powerful Applications in Image Forensics

TLDR
Using the image’s luminance channel and JPEG coefficients, the proposed idea is applicable to any procedure that involves the analysis of digital images and in which it is strongly suggested that the image authenticity be verified prior to beginning the analyzing process.

On Characterizations and Tests of Benford’s Law

Benford’s law defines a probability distribution for patterns of significant digits in real numbers. When the law is expected to hold for genuine observations, deviation from it can be taken as evi...

TLDR
A sophisticated statistical modeling framework that can be used to monitor and detect hints of individual fraudulent behavior in the context of international trade (i.e., imports and exports that are declared by national traders and shipping agents) is proposed.

Statistical detection of systematic election irregularities

TLDR
A parametric model quantifying the extent to which fraudulent mechanisms are present in elections with alleged fraud is developed and formulated, which produces robust outcomes with respect to the resolution of the data and therefore, allows for cross-country comparisons.

Integer percentages as electoral falsification fingerprints

We hypothesize that if election results are manipulated or forged, then, due to the well-known human attraction to round numbers, the frequency of reported round percentages can be increased. To test
