Can ChatGPT be a good follower of academic paradigms? Research quality evaluations in conflicting areas of sociology
Mike Thelwall, Ralph Schroeder, Meena Dhanda
Purpose: It has become increasingly likely that Large Language Models (LLMs) will be used to score the quality of academic publications to support research assessment goals in the…
Maximum softly penalised likelihood in factor analysis
Philipp Sterzinger, Ioannis Kosmids, Irini Moustaki
Estimation in exploratory factor analysis often yields estimates on the boundary of the parameter space. Such occurrences, known as Heywood cases, are characterised by non-positive…
Ingroup bias is prevalent in user reports of hate and abuse online
Florence E. Enock, Helen Z. Margetts, Jonathan Bright
The prevalence of online hate and abuse is a pressing global problem. While tackling such societal harms is a priority for research across the social sciences, it is a difficult ta…
Deep learning four decades of human migration
Thomas Gaskin, Guy J. Abel
We present a novel and detailed dataset on origin-destination annual migration flows and stocks between 230 countries and regions, spanning the period from 1990 to the present. Our…
Determining a graph from its reconfiguration graph
Gaétan Berthe, Caroline Brosse, Brian Hearn +3
Given a graph and a natural number , the -recolouring graph is the graph whose vertices are the -colourings of and whose edges link pairs of col…
Accountable Liveness
Andrew Lewis-Pye, Joachim Neu, Tim Roughgarden +1
Safety and liveness are the two classical security properties of consensus protocols. Recent works have strengthened safety with accountability: should any safety violation occur,…
Large language models in finance : what is financial sentiment?
Kemal Kirtac, Guido Germano
Financial sentiment has become a crucial yet complex concept in finance, increasingly used in market forecasting and investment strategies. Despite its growing importance, there re…
Edge isoperimetry of lattices
Cameron Strachan, Konrad Swanepoel
We present two results related to an edge-isoperimetric question for Cayley graphs on the integer lattice asked by Ben Barber and Joshua Erde [Isoperimetry of Integer Lattices, Dis…
Dynamically optimal portfolios for monotone mean--variance preferences
Aleš Černý, Johannes Ruf, Martin Schweizer
Monotone mean-variance (MMV) utility is the minimal modification of the classical Markowitz utility that respects rational ordering of investment opportunities. This paper provides…
On a fast consistent selection of nested models with possibly unnormalized probability densities
Rong Bian, Kung-Sik Chan, Bing Cheng +1
Models with unnormalized probability density functions are ubiquitous in statistics, artificial intelligence and many other fields. However, they face significant challenges in mod…

Morpheus Consensus: Excelling on trails and autobahns
Andrew Lewis-Pye, Ehud Shapiro
Recent research in consensus has often focussed on protocols for State-Machine-Replication (SMR) that can handle high throughputs. Such state-of-the-art protocols (generally DAG-ba…
Top eigenpair statistics of diluted Wishart matrices
Barak Budnick, Preben Forer, Pierpaolo Vivo +3
Using the replica method, we compute the statistics of the top eigenpair of diluted covariance matrices of the form , where is a…
