Modesty as a Condition for Circular Economy Transition Success

Modesty as a Condition for Circular Economy Transition SuccessThe Promise and Challenges of a Circular Economy TransitionThe circular economy offers much promise. Circularity is meant to be a pathway to material efficiency, energy transitions, green jobs, profitable business opportunities, reduced volatility in price of inputs, secured supplies of critical materials, increased customer experiences

Analyzing Disparity and Rates of Morphological Evolution with Model-Based Phylogenetic Comparative Methods

Understanding variation in rates of evolution and morphological disparity is a goal of macroevolutionary research. In a phylogenetic comparative methods framework, we present three explicit models for linking the rate of evolution of a trait to the state of another evolving trait. This allows testing hypotheses about causal influences on rates of phenotypic evolution with phylogenetic comparative

Sympathizing With the Radical Right : Effects of Mainstream Party Recognition and Control of Prejudice

The electoral success of radical right parties throughout Western Europe is the biggest change to these formerly stable party systems. Several studies have identified that mainstream parties can shape the trajectory of radical right parties. Our aim is to contribute to this literature, and to investigate if and how radical right parties gain from mainstream party recognition. Theoretically, we dra

Investigating practitioners’ perceived self- confidence and practices for multilingual children with developmental language disorder : The case of Sweden

The aim of the present study is twofold: to explore the assessment andintervention practices of Swedish practitioners (mainly Speech and LanguageTherapists: SLTs) for multilingual children with Developmental LanguageDisorders (DLD) and to explore to which extent they perceive themselves asconfident with respect to assessment and intervention. The data comes fromthe Swedish part of the survey by th

Introduction

Inledning till översättningsvolymen "The Forbidden Door" som innehåller dikter av den svenske poeten Lasse Söderberg (f. 1931), översatta till engelska av Lars Gustaf Andersson och Carolyn Forché.

Zooplankton responses to multiple threats within and across generations

In their natural environments, organisms are unlikely to be distributed randomly but instead they are constantly faced with multiple and variable threats. In order to maximise survival, they need to be able to perceive the present threat level and respond accordingly. In aquatic ecosystems, two common threats for crustacean zooplankton are predation and ultraviolet radiation (UVR). Despite the gro

Some Notes on Post-Quantum Cryptanalysis

Cryptography as it is used today relies on a foundational level on the assumptionthat either the Integer Factoring Problem (IFP) or the DiscreteLogarithm Problem (DLP) is computationally intractable. In the 1990s PeterShor developed a quantum algorithm that solves both problems in polynomialtime. Since then alternative foundational mathematical problems to replace IFPand DLP have been suggested. T

Tight Size-Degree Bounds for Sums-of-Squares Proofs

We exhibit families of 4-CNF formulas over n variables that have sums-of-squares (SOS) proofs of unsatisfiability of degree (a.k.a. rank) d but require SOS proofs of size nΩ ( d ) for values of d = d(n) from constant all the way up to nδ for some universal constant δ. This shows that the nO ( d ) running time obtained by using the Lasserre semidefinite programming relaxations to find degree-d SOS

Extending the theoretical grounding of mobilities research : transport psychology perspectives

This paper reconsiders the new mobilities paradigm and its relevance for the understanding of transport systems and behaviour. It argues that the mobilities field will gain from more systematically drawing on conceptual and empirical insights from psychology to complement insights as mostly derived from sociology, geography, innovation studies, anthropology, cultural studies and continental philos

Prediction of Sound Insulation Using Artificial Neural Networks—Part I : LightweightWooden Floor Structures

The artificial neural networks approach is applied to estimate the acoustic performance for airborne and impact sound insulation curves of different lightweight wooden floors. The prediction model is developed based on 252 standardized laboratory measurement curves in one-third octave bands (50-5000 Hz). Physical and geometric characteristics of each floor structure (materials, thickness, density,

ESTRO-ACROP guideline on surface guided radiation therapy

Surface guidance systems enable patient positioning and motion monitoring without using ionising radiation. Surface Guided Radiation Therapy (SGRT) has therefore been widely adopted in radiation therapy in recent years, but guidelines on workflows and specific quality assurance (QA) are lacking. This ESTRO-ACROP guideline aims to give recommendations concerning SGRT roles and responsibilities and

Antimicrobial, antiparasitic, anti-inflammatory, and cytotoxic activities of Lopezia racemosa

The present study investigates the potential benefits of the Mexican medicinal plant Lopezia racemosa (Onagraceae). Extracts and fractions from aerial parts of this plant were assessed to determine their antibacterial, antifungal, antiparasitic, anti-inflammatory and cytotoxic activities in vitro. Aerial parts of the plant were extracted with various solvents and fractionated accordingly. Extracts
