Ecologically unequal exchange : Disagreements with Somerville
Somerville's rejoinder highlights some fundamental divergences between ecologically unequal exchange theory and the classical Marxist position. This brief intervention addresses a few points in his rejoinder that are particularly illustrative of the incompatibility of the two frameworks. It is argued that historical materialism should acknowledge the materiality of world trade as foundational to g
A randomized controlled trial of the effectiveness of teacher continued professional development on student language outcomes
BACKGROUND: Continued professional development (CPD) is required for updated skills and knowledge. This study evaluates the efficacy of a CPD programme for mainstream school teachers.AIMS: In an 11-week intervention programme, speech-language therapists (SLTs) presented the participating teachers with whole-class teaching techniques aimed at creating a language and communication-supporting classro
Validation of the Swedish version of PROMIS-29v2 and FACIT-Dyspnea Index in patients with systemic sclerosis
Purpose: To evaluate the reliability, internal consistency, and construct validity of the Swedish versions of PROMIS-29 and Functional Assessment of Chronic Illness Therapy-Dyspnea (FACIT-Dyspnea) instruments in patients with systemic sclerosis (SSc). Methods: In a cross-sectional study, consecutive SSc patients completed a paper-based survey. Internal consistency was assessed using Cronbach’s alp
Analogy as a search procedure : a dimensional view
In this paper, we outline a comprehensive approach to composed analogies based on the theory of conceptual spaces. Our algorithmic model understands analogy as a search procedure and builds upon the idea that analogical similarity depends on a conceptual phenomena called ‘dimensional salience.’ We distinguish between category-based, property-based, event-based, and part-whole analogies, and p
Prevalence of endometrioma and deep infiltrating endometriosis at transvaginal ultrasound examination of subfertile women undergoing assisted reproductive treatment
Objective: To estimate the prevalence of endometrioma and deep infiltrating endometriosis (DIE), assessed by systematic transvaginal ultrasound examination, in women with subfertility accepted for their first assisted reproductive treatment and to describe the prevalence of endometriotic lesions in different anatomical locations of the pelvis. Design: Cross-sectional study. Setting: Reproductive M
Giemsa-negative chromosome bands preferentially recombine in cancer-associated translocations and gene fusions
Chromosome abnormalities, in particular translocations, and gene fusions are hallmarks of neoplasia. Although both have been recognized as important drivers of cancer for decades, our knowledge of the characterizing features of the cytobands involved in recombinations is poorly understood. The present study, based on a comparative analysis of 10 442 translocation breakpoints and 30 762 gene fusion
Clinical performance and robustness evaluation of plasma amyloid-β42/40 prescreening
Introduction: Further evidence is needed to support the use of plasma amyloid β (Aβ) biomarkers as Alzheimer's disease prescreening tools. This study evaluated the clinical performance and robustness of plasma Aβ42/Aβ40 for amyloid positivity prescreening. Methods: Data were collected from 333 BioFINDER and 121 Alzheimer's Disease Neuroimaging Initiative study participants. Risk and predictive val
School Nurses’ Perspectives on Health among School-Aged Children and Adolescents During the COVID-19 Pandemic
The aim of this study was to investigate school nurses’ perspectives on students’ health during the COVID-19 pandemic in Sweden in 2021. A cross-sectional survey design was used with school nurses (n = 225) working in schools in Sweden from elementary to upper secondary levels. The Clausson School Nurse Perception Questionnaire was used with two additional questions about the COVID-19 pandemic. Th
How broad is the selfing syndrome? Insights from convergent evolution of gene expression across species and tissues in the Capsella genus
The shift from outcrossing to selfing is one of the main evolutionary transitions in plants. It is accompanied by profound effects on reproductive traits, the so-called selfing syndrome. Because the transition to selfing also implies deep genomic and ecological changes, one also expects to observe a genomic selfing syndrome. We took advantage of the three independent transitions from outcrossing t
Using Novel Molecular-Level Chemical Composition Observations of High Arctic Organic Aerosol for Predictions of Cloud Condensation Nuclei
Predictions of cloud droplet activation in the late summertime (September) central Arctic Ocean are made using κ-Kohler theory with novel observations of the aerosol chemical composition from a high-resolution time-of-flight chemical ionization mass spectrometer with a filter inlet for gases and aerosols (FIGAERO-CIMS) and an aerosol mass spectrometer (AMS), deployed during the Arctic Ocean 2018 e
Affects, emotions and interaction : the methodological promise of video data analysis in peace research
Methodologically, Peace Research has long been dominated by words, numbers, and sometimes images. This article suggests also integrating Video Data Analysis (VDA) into the analytical toolbox of Peace Research so as to explore the potential of the millions of videos of relevance for the study of peace and conflict that can be found online and beyond. The article introduces VDA and shows how the met
Quantum Mechanical Calculations of Redox Potentials of the Metal Clusters in Nitrogenase
We have calculated redox potentials of the two metal clusters in Mo-nitrogenase with quantum mechanical (QM) calculations. We employ an approach calibrated for iron–sulfur clusters with 1–4 Fe ions, involving QM-cluster calculations in continuum solvent and large QM systems (400–500 atoms), based on structures from combined QM and molecular mechanics (QM/MM) geometry optimisations. Calculations on
Law as the Game of Truth in the Case of Xerzan Cemetery
From legal positivism describing law through correctness and certainty to critical studies challenging law's formal truth-seeking by elaborating on its inevitable distance to experience, the relation of law to truth has been long discussed. Adopting a Foucauldian understanding of truth that depends on the deployment of various knowledges, this article focuses on the law's participation in truth-ma

Cross-sectional associations of optimism with artery calcification and function : The SCAPIS study
Background: An increasing amount of research indicates that positive psychological factors, such as optimism, might be beneficial for cardiovascular health. However, most studies have focused on cardiovascular events. The present study aimed to investigate associations between optimism and subclinical outcomes related to cardiovascular health. Methods: This cross-sectional study used data from SCA
Unified method for measuring entropy differences between coexisting surface phases using low energy electron microscopy
We demonstrate the ability of low energy electron microscopy (LEEM) to extract fundamental information in surface phase transitions during in situ observations of complex semiconductor surfaces. We utilize established LEEM techniques and develop a methodology that enables us to calculate the surface entropy difference using only LEEM measurements without the need for external characterization. We
The role of business angels in the new financial landscape
Both access to and use of external sources of finance by entrepreneurial ventures have transformed significantly over the past 10-15 years, which may have induced an important shift in the role of business angels (BAs). In this chapter we elaborate on this changing role of BAs, and in particular on the value creation provided by BAs in the new financial landscape. We propose to reframe the discuss
Noninvasive detection of any-stage cancer using free glycosaminoglycans
Cancer mortality is exacerbated by late-stage diagnosis. Liquid biopsies based on genomic biomarkers can noninvasively diagnose cancers. However, validation studies have reported ~10% sensitivity to detect stage I cancer in a screening population and specific types, such as brain or genitourinary tumors, remain undetectable. We investigated urine and plasma free glycosaminoglycan profiles (GAGomes
Bioengineered nerve conduits and wraps for peripheral nerve repair of the upper limb
Background: Traumatic peripheral nerve injury is common and incurs significant cost to individuals and society. Healing following direct nerve repair or repair with autograft is slow and can be incomplete. Several bioengineered nerve wraps or devices have become available as an alternative to direct repair or autologous nerve graft. Nerve wraps attempt to reduce axonal escape across a direct repai
