We study the effects of counterfactual teacher-to-classroom assignments on average student achievement in U.S. elementary and middle schools. We use the Measures of Effective Teaching (MET) experiment to semiparametrically identify the average reallocation effects (AREs) of such assignments. Our identification strategy exploits the random assignment of teachers to classrooms in MET schools. To acc

Purpose: This paper evaluates a theory-driven, interactive hand hygiene (HH) intervention, the Safe Hands project, based on theories of organizational learning and culture including leadership support, dialogue and co-creation. Design: This prospective quasi-experimental study used unobtrusive overt observations to evaluate adherence to HH recommendations after implementing an infection-prevention

A new neutron activation analysis system is currently being designed at Lund University. The design incorporates a compact accelerator driven neutron source, based on a 3 MV Pelletron accelerator and a pneumatic sample conveyor to transport samples from the neutron source to a measurement station consisting of an array of high-purity Ge γ-ray detectors. A prototype for this new station is currentl

Följande text syftar till att belysa frågan om etik och dess relation till autenticitet (respektive inautenticitet) med tilläggsfrågan om språkets betydelse för förståelsen av den ordlösa erfarenheten i det autentiska mötet mellan ett ”jag” och ett ”du” utifrån framför allt den fransk-litauiske filosofen Emmanuel Levinas (1906–1995) ansikte-mot-ansikte- etik. Frågan om jagets förhållande till den

The purpose of this chapter is to identify and classify proposed business model innovation tools through a literature review of academic publications. We classified the tools into three categories: innovation process stage, strategic objective and size of firm. Our main findings are that the overall number of business model innovation (BMI) tools described in the research literature is limited mos

Although AlGaN/GaN HEMTs with high power and current gain have been demonstrated in RF device applications, at high signal operation they show an inherent non-linear behavior which leads to gain compression and signal distortion. Polarization-doped AlGaN/GaN HEMTs, with a compositionally graded channel enables a linear response improvement through formation of a 3-D electron gas. In this work, we

Results on integration of InAs on W films through template assisted selective epitaxy are presented. The InAs crystals are analysed using SEM, electron beam backscattering and in-situ electrical measurements. A high yield of single crystalline InAs can be obtained for certain template diameters and pitches which demonstrates that this is a viable route to integrate III-V semiconductors in the back

Flera idrottsforskare understryker språkets roll i undervisning i skolämnet Idrott och hälsa (Larsson & Karlefors, 2015; Nyberg & Larsson, 2014; Schenker et al., 2019), och ämnesspråket har påståtts vara svagt inte minst i de delar som hör samman med hälsa (Redelius et al., 2009; Schenker, 2018). I denna artikel presenteras resultaten av en pilotstudie av ämnesspråket i skolämnet Idrott oc

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

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

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

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

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

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

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

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
