No Time to Talk! : Teachers' Perceptions of Organizational Communication and Work-related Health

Denna avhandling syftar till att utöka kunskapsbasen om hur grundskolelärare i Sverige kommunicerar och interagerar i sitt yrke och vilka arbetsrelaterade hälsoproblem de upplever. Avhandlingen bygger på två studier, vilka genererat tre artiklar. Papper I är baserat på resultat från en explorativ studie med fokusgruppsmetodik. I denna studie undersöktes arbetsplatskommunikationspraxis bland skolläDuring recent years, schoolteachers in Sweden have experienced many reforms and societal changes, resulting in altered conditions for work. Subsequently, many teachers have reported an increased workload and reduced well-being. In addition, previous research has identified a need for more contextually anchored measures of demands and resources pertaining to teachers’ work situation.This dissertati

Hosseusiella and Rehmanniella, two new genera in the Teloschistaceae

Two new genera in the subfamily Teloschistoideae (Teloschistaceae, Teloschistales) are described: Hosseusiella S. Y. Kondr., L. Lőkös et A. Thell for the Caloplaca chilensis group including three South American species and Rehmanniella S. Y. Kondr. et J.-S. Hur for the new species, R. wirthii S. Y. Kondr. from South Africa. The new genera are supported by a three-gene phylogeny based on ITS1/ITS2

Filosofiska teorier om mänskliga rättigheter : en kritisk analys

I detta kapitel diskuteras kritiskt två relaterade tendenser i filosofiska teorier om mänskliga rättigheter. Den första handlar om synen på rättighetsinnehavaren. Mänskliga rättigheter har kommit att betraktas som något som människor ”har” och då uppstår frågan vad det är med människor som gör dem till rättighetsinnehavare. Ett vanligt svar är att människor besitter den moraliska värdighet som gör

In Situ Synthesis and Single Crystal Synchrotron X-ray Diffraction Study of ht-Sn3Sb2 : An Example of How Complex Modulated Structures Are Becoming Generally Accessible

ConspectusRecent developments in X-ray sources and detectors and the parallel development of software for nonstandard crystallography has made analysis of very complex structural problems accessible to nonexperts. Here, we report the successful solution of the structure of ht-Sn3Sb2, an analysis that presents several challenges but that is still manageable in a relatively straightforward way. This

Reflection of Coherent Millimeter-Wave Wavelets on Dispersive Materials : A Study on Porcine Skin

Differences in the material reflection are required for any contrast in microwave- and millimeter-wave (mm-wave) imaging systems. Therefore, the dielectric properties, which determine the reflection of materials, need to be characterized. The characterization of skin and other biological tissue is, therefore, necessary, to apply imaging systems for instance in cancer diagnosis. In this paper, shor

Structural and Biophysical Characterization of Human EXTL3 : Domain Organization, Glycosylation, and Solution Structure

Heparan sulfate proteoglycans are proteins substituted with one or more heparan sulfate (HS) polysaccharides, found in abundance at cell surfaces. HS chains influence the activity of many biologically important molecules involved in cellular communication and signaling. The exostosin (EXT) proteins are glycosyltransferases in the Golgi apparatus that assemble HS chains on HSPGs. The EXTL3 enzyme m

Altered white matter microstructure in lupus patients : A diffusion tensor imaging study

Background: The purpose of this study was to investigate whether white matter microstructure is altered in patients suffering from systemic lupus erythematosus (SLE), and if so, whether such alterations differed between patients with and without neuropsychiatric symptoms. Methods: Structural MRI and diffusion tensor imaging (DTI) were performed in 64 female SLE patients (mean age 36.9 years, range

GaAs Nanowire pn-Junctions Produced by Low-Cost and High-Throughput Aerotaxy

Semiconductor nanowires could significantly boost the functionality and performance of future electronics, light-emitting diodes, and solar cells. However, realizing this potential requires growth methods that enable high-throughput and low-cost production of nanowires with controlled doping. Aerotaxy is an aerosol-based method with extremely high growth rate that does not require a growth substra

Fractures among patients with dizziness : A ten-year follow-up

Background: The number of elderly people persons suffering from dizziness is substantial, and dizziness is a risk factor for falls and fractures. Fall-related fractures represent a major public health issue. Longitudinal studies can help find ways of predicting fall-related fractures among frail elderly persons with multisensory dizziness. The aim of the present study was therefore to investigate

Interaction of dietary and genetic factors influencing body iron status and risk of type 2 diabetes within the EPIC-InterAct study

OBJECTIVE Meat intake has been consistently shown to be positively associated with incident type 2 diabetes. Part of that association may be mediated by body iron status, which is influenced by genetic factors. We aimed to test for interactions of genetic and dietary factors influencing body iron status in relation to the risk of incident type 2 diabetes. RESEARCH DESIGN AND METHODS The case-cohor

Reproductive hormone levels predict changes in frailty status in community-dwelling older men : European male ageing study prospective data

Context: Clinical sequelae of androgen deficiency share common features with frailty. Evidence supporting the role of androgens in the development of frailty is limited and conflicting. Objective: To determine associations between male reproductive hormones and prospective changes in frailty status. Design/Setting: A 4.3-year prospective cohort study of community-dwelling men participating in the

Validation of prediction model for successful vaginal birth after Cesarean delivery based on sonographic assessment of hysterotomy scar

Objective: To validate a prediction model for successful vaginal birth after Cesarean delivery (VBAC) based on sonographic assessment of the hysterotomy scar, in a Swedish population. Methods: Data were collected from a prospective cohort study. We recruited non-pregnant women aged 18–35 years who had undergone one previous low-transverse Cesarean delivery at ≥ 37 gestational weeks and had had no

compact optical setup for quantitative and spatially resolved measurement of atomic alkali concentration in combustion is demonstrated. Tunable diode laser absorption spectroscopy and laser-induced fluorescence are combined using a single continuous wave diode laser to measure the line-integration concentration and the relative distribution simultaneously, thereby obtaining the absolute concentrat

One page of text : Eye movements during regular and thorough reading, skimming, and spell checking

Eye movements during regular reading, thorough reading, skimming, and spell checking of single pages of text were measured, to investigate how high-level reading tasks elicited by instructions affect reading behavior. Word frequency and word length effects were found. All results were compared to regular reading. Thorough reading involved longer total reading times and more rereading, and resulted

Objectives: To use a population pharmacokinetic approach to define maximally effective meropenem dosing recommendations for treatment of Acinetobacter baumannii and Pseudomonas aeruginosa infections in a large cohort of patients with septic shock. Methods: Adult patients with septic shock and conserved renal function, treated with meropenem, were eligible for inclusion. Seven blood samples were co

MR and CT data with multiobserver delineations of organs in the pelvic area-Part of the Gold Atlas project

Purpose: We describe a public dataset with MR and CT images of patients performed in the same position with both multiobserver and expert consensus delineations of relevant organs in the male pelvic region. The purpose was to provide means for training and validation of segmentation algorithms and methods to convert MR to CT like data, i.e., so called synthetic CT (sCT). Acquisition and validation

UVI hos kvinnor – akut cystit

Hos friska kvinnor är akut cystit besvärande men ofarligt. Infektionen läker spontant, behandling förkortar tiden med symtom och ges i symtomlindrande syfte. Akut cystit är en bakteriell infektion i urinblåsans slemhinna och definieras som nytillkommen sveda, trängningar och ökad frekvens till vattenkastning samtidigt med bakterier i urinen. Diagnostiken i primärvården baseras framför allt på klin

MEPS as climate policy

Researchers from Sweden (IIIEE, Lund University) and the US (Enervee) have found that minimum energy per-formance standards (MEPS) for home appliances are an effective alternative to stand-alone carbon pricing. A modest tightening of MEPS is already sufficient to account for climate externalities. For several appliances, carbon prices would have to increase manifold to provide the same incentives
