Too much of a good thing? Entrepreneurial orientation and the non-linear governance effects of SaaS platforms
Jacopo Ballerini, Magali Pino, Michal Kuděj +1
This study investigates how entrepreneurial orientation (EO) affects governance of SaaS platforms in SMEs, including strategy alignment and long-term governance performance. This s…
Refined thresholds for inconsistency: The effect of the graph associated with incomplete pairwise comparisons
Kolos Csaba Ágoston, László Csató
The inconsistency of pairwise comparisons remains difficult to interpret in the absence of acceptability thresholds. The popular 10% cut-off rule proposed by Saaty has recently bee…
Are penalty shootouts better than a coin toss? Evidence from international club football in Europe
László Csató, Dóra Gréta Petróczy
Penalty shootouts play a crucial role in the knockout stage of major football tournaments. Their importance has substantially increased from the 2021/22 season, when the Union of E…
An experimental approach: Converting verbal expressions to numerical scales
Zsombor Szádoczki, Sándor Bozóki, László Sipos +1
One of the key issues in decision problems is the selection and use of the appropriate response scale. In this paper verbal expressions are converted into numerical scales for a su…
Evolution and determinants of firm-level systemic risk in local production networks
Anna Mancini, Balázs Lengyel, Riccardo Di Clemente +1
Recent crises like the Covid-19 pandemic and geopolitical tensions have exposed vulnerabilities and caused disruptions of supply chains, leading to product shortages, increased cos…
Binary Self-Selective Voting Rules
Héctor Hermida-Rivera, Toygar T. Kerman
This paper introduces a novel binary stability property for voting rules-called binary self-selectivity-by which a society considering whether to replace its voting rule using itse…
Augmenting the availability of historical GDP per capita estimates through machine learning
Philipp Koch, Viktor Stojkoski, César A. Hidalgo
Can we use data on the biographies of historical figures to estimate the GDP per capita of countries and regions? Here we introduce a machine learning method to estimate the GDP pe…
ALT: A Python Package for Lightweight Feature Representation in Time Series Classification
Balázs P. Halmos, Balázs Hajós, Vince Á. Molnár +2
We introduce ALT, an open-source Python package created for efficient and accurate time series classification (TSC). The package implements the adaptive law-based transformation (A…
Eigenvalue-Based Randomness Test for Residual Diagnostics in Panel Data Models
Marcell T. Kurbucz, Betsabé Pérez Garrido, Antal Jakovác
This paper introduces the Eigenvalue-Based Randomness (EBR) test - a novel approach rooted in the Tracy-Widom law from random matrix theory - and applies it to the context of resid…
Ranking matters: Does the new format select the best teams for the knockout phase in the UEFA Champions League?
László Csató, Karel Devriesere, Dries Goossens +3
Starting in the 2024/25 season, the Union of European Football Associations (UEFA) has fundamentally changed the format of its club competitions: the group stage has been replaced…
Existence theorem on the UV limit of Wilsonian RG flows of Feynman measures
Andras Laszlo, Zsigmond Tarcsay, Jobst Ziebell
In nonperturbative formulation of Euclidean signature quantum field theory (QFT), the vacuum state is characterized by the Wilsonian renormalization group (RG) flow of Feynman meas…
Increasing competitiveness by imbalanced groups: The example of the 48-team FIFA World Cup
László Csató, András Gyimesi
A match played in a sports tournament can be called stakeless if at least one team is indifferent to its outcome because it already has qualified or has been eliminated. Such a gam…
Adaptive Law-Based Transformation (ALT): A Lightweight Feature Representation for Time Series Classification
Marcell T. Kurbucz, Balázs Hajós, Balázs P. Halmos +2
Time series classification (TSC) is fundamental in numerous domains, including finance, healthcare, and environmental monitoring. However, traditional TSC methods often struggle wi…
Swiss-system chess tournaments and unfairness
László Csató, Alex Krumer
The Swiss system is an increasingly popular competition format as it provides a favourable trade-off between the number of matches and ranking accuracy. However, there is no empiri…
Measuring Research Interest Similarity with Transition Probabilities
Attila Varga, Sadamori Kojaku, Filipi Nascimento Silva
We introduce a family of paper and author similarity measures based on the concept that papers are more similar if they are more likely to be retrieved during a literature search f…
The Software Complexity of Nations
Sándor Juhász, Johannes Wachs, Jermain Kaminski +1
Despite the growing importance of the digital sector, research on economic complexity and its implications continues to rely mostly on administrative records, e.g. data on exports,…
Exploring LGBTQ+ Bias in Generative AI Answers across Different Country and Religious Contexts
Lilla Vicsek, Anna Vancsó, Mike Zajko +1
Previous discussions have highlighted the need for generative AI tools to become more culturally sensitive, yet often neglect the complexities of handling content about minorities,…
Competitive balance in the UEFA Champions League group stage: Novel measures show no evidence of decline
László Csató, Dóra Gréta Petróczy
Competitive balance, which refers to the level of control teams have over a sports competition, is a crucial indicator for tournament organisers. According to previous studies, com…
Misaligned incentives in sports: A mathematical analysis of the post-2024 UEFA Champions League qualification
László Csató, Sergey Ilyin
UEFA declares that it is committed to respecting the fundamental values of sports. However, the qualification rules of the post-2024 UEFA Champions League are shown to be unfair: a…
Large Language Models (LLMs) as Agents for Augmented Democracy
Jairo Gudiño-Rosero, Umberto Grandi, César A. Hidalgo
We explore an augmented democracy system built on off-the-shelf LLMs fine-tuned to augment data on citizen's preferences elicited over policies extracted from the government progra…
The dynamics of leadership and success in software development teams
Lorenzo Betti, Luca Gallo, Johannes Wachs +1
From science to industry, teamwork plays a crucial role in knowledge production and innovation. Most studies consider teams as static groups of individuals, thereby failing to capt…
Urban highways are barriers to social ties
Luca Maria Aiello, Anastassia Vybornova, Sándor Juhász +2
Urban highways are common, especially in the US, making cities more car-centric. They promise the annihilation of distance but obstruct pedestrian mobility, thus playing a key role…
Tournament design: A review from an operational research perspective
Karel Devriesere, László Csató, Dries Goossens
Every sport needs rules. Tournament design refers to the rules that determine how a tournament, a series of games between a number of competitors, is organized. This study aims to…
