Redaktionell introduktion till tidskriften Fronesis nr 64-65, tema Algoritmer.
This article introduces a logic to reason about a well-known model of opinion dynamics in social networks initially developed by Morris DeGroot as well as Keith Lehrer and Carl Wagner. The proposed logic is an extension of Łukasiewicz' fuzzy logic with additional equational expressivity, modal operators, machinery from hybrid logic and dynamic modalities. The model of opinion dynamics in social ne
Människor kategoriserar och ordnar världen omkring sig genom att konstruera gränser, producera värderingar, rangordningar och kvantifierade data. Att undersöka hur sådana ordningar konstrueras, reproduceras och ifrågasätts har länge varit en central fråga för kunskapssociologin. Att förstå sådana processer idag innebär att vi i allt större utsträckning måste förstå hur algoritmer kommit att bli en
The growth of Bi on both the In-terminated (A) face and the As-terminated (B) face of InAs(1 1 1) has been investigated by low-energy electron diffraction, scanning tunnelling microscopy, and photoelectron spectroscopy using synchrotron radiation. The changes upon Bi deposition of the In 4d and Bi 5d5/2 photoelectron signals allow to get a comprehensive picture of the Bi/InAs(1 1 1) interface. Fro
The role of values in climate-related decision-making is a prominent theme of climate communication research. The present study examines whether forest professionals are more driven by values than scientists are, and if this results in value polarization. A questionnaire was designed to elicit and assess the values assigned to expected effects of climate change by forest professionals and scientisThe role of values in climate-related decision-making is a prominent theme of climatecommunication research.

Why did heraldry originate? This question has often been answered with references to changes in the military equipment in the 12th century, especially the introduction of the closed helmet. But recent research gives reason to question this theory. The introduction of the closed helmet and the origin of heraldry did not coincide chronologically. There are other changes in the military equipment, anWhy did heraldry originate?

A channel sounder is an advanced measurement system to estimate the behavior of wireless propagation channels. In this paper, we present the antenna array design for a 28GHz massive multiple-input multiple-output system, capable of measuring 256×128 dual-polarized channels, including dynamic properties of angular, delay, Doppler, and polarization parameters, respectively. Unique in comparison to o
In this work, X-ray absorption spectroscopy (XAS) and site-selective X-ray emission spectroscopy (XES) were used to measure the oxygen K-edge (OC=O,1s and OCO − ,1s) of oxalic acid, with theoretical calculations performed to reproduce the spectra observed. Structure sampling of a cluster model was performed using an ab initio molecular dynamics trajectory. Relative XES intensities from core-hole e
Multinuclear metal active sites are widely used as catalytic reaction centers in metalloenzymes and generally show high catalytic activity. For example, laccases are known to catalyze the oxygen reduction reaction (ORR) to water at a multinuclear copper site with almost no energy loss. The ORR is an important reaction not only in oxygenic respiration but also in future energy generation devices su
Purpose: The aim of this study was to compare the effects of four months of two types of structured training regimes, static standing (StS) versus dynamic standing (DyS), on passive range of motion (PROM) and spasticity in the hip among non-ambulatory children with cerebral palsy.Method: Twenty non-ambulatory children with cerebral palsy participated in an exercise intervention study with a crosso
Biographical essay on Märta Strömberg, professor of Archaeology in Lund. She was one of the first female archaeologists that took place in the university world. She became a committed mentor for generations of students, doctoral students and colleagues. Her archaeological investigations of the Stone Age megalithic tombs, the Bronze Age and the Iron Age grave fields and settlements became methodolo
Combating climate change and transitioning to fossil-free energy are two central and interdependent challenges facing humanity today. Governing the nexus of these challenges is complex, and includes multiple intergovernmental and transnational institutions. This book analyses the governance interactions between such institutions, and explores their consequences for legitimacy and effectiveness. Us
The introduction first explains the rationale and theoretical and empirical contributions of the edited volume. The book seeks to address a considerable gap of knowledge of the nature of the relationship between institutions governing the climate-energy nexus in a multilevel context. In particular, there is scant research on consequences on the legitimacy and effectiveness of governance arrangemen
The concluding chapter first summarizes some of the volume’s main results along the four evaluative themes. In terms of coherence and management, the three policy fields under scrutiny – renewable energy, fossil fuel subsidy reform and carbon pricing – are roughly marked by coordination, rather than competition or outright harmony. Regarding legitimacy, the specializations and work backgrounds of
This chapter establishes four evaluative themes that will be employed across this volume to analyze the institutional complexity of policy fields in the climate-energy nexus: coherence, management, legitimacy, and effectiveness. Coherence among institutions is conceptualized along four dimensions: convergence on an overarching core norm for the policy field, balanced coverage and distribution of m
This study investigates how related variety in the regional employment mix affects the innovation output of a region. Departing from the idea of recombinant innovation, previous research has arguedthat related variety enhances regional innovation as inter-industry knowledge spillovers occur more easily between different but cognitively similar industries. This study combines a novel dataset and re
Agricultural production systems are affected by complex interactions between social and ecological factors, which are often hard to integrate in a common analytical framework. We evaluated differences in crop production among farms by integrating components of several related research disciplines in a single socio-ecological analysis. Specifically, we evaluated spring barley (Hordeum vulgare, L.)
