Integrability of a Globally Coupled Complex Riccati Array : Quadratic Integrate-and-Fire Neurons, Phase Oscillators, and All in between

We present an exact dimensionality reduction for dynamics of an arbitrary array of globally coupled complex-valued Riccati equations. It generalizes the Watanabe-Strogatz theory [Integrability of a globally coupled oscillator array, Phys. Rev. Lett. 70, 2391 (1993).PRLTAO0031-900710.1103/PhysRevLett.70.2391] for sinusoidally coupled phase oscillators and seamlessly includes quadratic integrate-and

The ABC of happiness : Validation of the tridimensional model of subjective well-being (affect, cognition, and behavior) using Bifactor Polytomous Multidimensional Item Response Theory

Background: Happiness is often conceptualized as subjective well-being, which comprises people's evaluations of emotional experiences (i.e., the affective dimension: positive and negative feelings and emotions) and judgements of a self-imposed ideal (i.e., the cognitive dimension: life satisfaction). Recent research has established these two dimensions as primary parts of a higher order factor. Ho

Robust Simultaneous Stabilization Via Minimax Adaptive Control

The paper explores the usage of minimax adaptive controllers to guarantee finite L2 -gain simultaneous stabilization of linear time-invariant (LTI) plants. It is shown that a minimax adaptive controller simultaneously stabilizes any two multiple-input multiple-output (MIMO) P-stabilizable LTI plants when no LTI controller can achieve that, and the worst attained L2 -gain bound for the transient dy

Coalition agreements and governments’ policy-making productivity

One of the biggest challenges parties in multiparty governments face is making policies together and overcoming the risk of a policy stalemate. Scholars have devoted much attention to the study of how various institutions in cabinet and parliament help coalition parties with conflicting policy preferences to be efficient in the policy-making process. Coalition agreements are one of many instrument

Language and gender : Computerized text analyses predict gender ratios from organizational descriptions

Previous research has shown that language in job adverts implicitly communicates gender stereotypes, which, in turn, influence employees’ perceived fit with the job. In this way, language both reflects and maintains a gender segregated job market. The aim of this study was to test whether, and how, language in organizational descriptions reflects gender segregation in the organizations by the use

Cross-Platform Emotions and Audience Engagement in Social Media Political Campaigning : Comparing Candidates’ Facebook and Instagram Images in the 2020 US Election

This study provides a cross-platform, longitudinal investigation of pictures depicting political candidates posted to Facebook and Instagram over a 15-month period during the 2020 US election(n = 4,977). After motivating an exploratory research design, we set out to expound: the extent of cross-platform image posting across Facebook and Instagram; the emotion expression of politicians across the t

How bad is bad? Perceptual differences in the communication of severity in intimate partner violence

Accurate communication of the severity of violence in intimate relations is essential for the appropriate evaluation of offenders and victims in contexts such as court trials, custody cases, and the continuation of relationships. Using a new paradigm, this study quantifies discrepancies in how the severity of violence is communicated in texts written by offenders, victims, and bystanders who witne

Women Are Perceived to Have More Power Than Men in Domains That Are Viewed As Important in U.S. Tweets

Previous research of gender differences in power has largely focused on the public domain (e.g., leadership positions), and to a lesser extent power on the private domain (e.g., power in private relationships), where people may perceive these domains to be more or less important in their lives. We studied gender differences in preference weighted power (PWP) in different domains by weighting the p

Social Media Digital Architectures : A Platform-First Approach to Political Communication and Participation

This chapter outlines the architectural approach to researching digital politics. An architectural approach focuses on platform structures and how they mediate, and can actively affect, users’ political agency online and offline. I first chart the lineage of architectural approaches in the social sciences, from discourse architectures to digital architectures. Then, I describe the process of ‘mapp

From Epistemic Norms to Logical Rules : Epistemic Models for Logical Expressivists

In this paper I construct a system of semantics for classical and intuitionistic propositional logic based on epistemic norms governing belief expansion. Working in the AGM-framework of belief change, I give a generalisation of Gärdenfors’ notion of belief systems which can be defined without reference to a logical consequence operator by using a version of the Ramsey Test. These belief expansion

Linguistic : Application of LSA to predict linguistic maturity and language disorder in children

In this chapter we will describe applications of latent semantic analysis to assess semantic linguistic maturity in children and how well the method can predict whether a child has developmental language disorder (DLD), based on orally produced narratives. Assessment of narrative ability in preschool years captures important cognitive, linguistic and socio-pragmatic skills and is an important prog

Lexical Ambiguity in Political Rhetoric: Why Morality Doesn't Fit in a Bag of Words

How do politicians use moral appeals in their rhetoric? Previous research suggests that morality plays an important role in elite communication and that the endorsement of specific values varies systematically across the ideological spectrum. We argue that this view is incomplete since it only focuses on whether certain values are endorsed and not how they are contextualized by politicians. Using

Artistic expression in upper secondary school music program – perceptions, pedagogies, and assessment.

This presentation gives an overview of the results from the first part of an ongoing postdoc project in music education. This project aims to explore the role of artistic expression in the teachings at upper secondary school music program from the perspective of music teachers. The study focuses on two courses in which the concept artistic expression appears in the syllabus: Instrument and song 1-

Using deep learning to predict ideology from facial photographs: expressions, beauty, and extra-facial information

Deep learning techniques can use public data such as facial photographs to predict sensitive personal information, but little is known about what information contributes to the predictive success of these techniques. This lack of knowledge limits both the public’s ability to protect against revealing unintended information as well as the scientific utility of deep learning results. We combine conv

Separately and together, the four contributions in this book exemplify what staff at the Department of Communication and Media consider to comprise an excellent dissertation at the Ma

Debating the Populist Pariah : Changing Party Dynamics and Elite Rhetoric in the Swedish Riksdag

Radical right populist parties have often been treated as “pariahs,” being excluded from coalition politics in parliamentary democracies. We argue that negative rhetoric targeted at radical right populist parties in legislative debates is used by the established parties to distance themselves from such parties and that the incentives to do so depend on the political context. Using sentiment analys

One hundred years of excellence : the top one hundred authors of the Journal of Comparative Physiology A

The Journal of Comparative Physiology A is the premier peer-reviewed scientific journal in comparative physiology, in particular sensory physiology, neurophysiology, and neuroethology. Founded in 1924 by Karl von Frisch and Alfred Kühn, it celebrates its 100th anniversary in 2024. During these 100 years, many of the landmark achievements in these disciplines were published in this journal. To comm

Can sign-naïve adults learn about the phonological regularities of an unfamiliar sign language from minimal exposure?

Adults can extract phonological regularities from just several minutes’ exposure to natural-istic input of an unknown spoken language (Gullberg et al., 2010). We examined whether such implicit statistical learning mechanisms also operate in the sign language modality. The input materials con-sisted of a continuous sign stream in the form of a weather forecast in Svenskt Teckenspråk (STS). L1-speak

Inverse stochastic resonance in adaptive small-world neural networks

Inverse stochastic resonance (ISR) is a counterintuitive phenomenon where noise reduces the oscillation frequency of an oscillator to a minimum occurring at an intermediate noise intensity, and sometimes even to the complete absence of oscillations. In neuroscience, ISR was first experimentally verified with cerebellar Purkinje neurons [Buchin et al., PLOS Comput. Biol. 12, e1005000 (2016)]. These
