Sammenhæng i læreruddannelse: Hvad, hvorfor, og i erkendelsen af kompleksitet?

The article departs from the observation, that without further definition the concept coherence is very frequently used in didactical and teacher educational discussions and furthermore used with very positive connotations. Based on theoretical and empirical analyses the article describes categorically different meanings of the concept. One conclusion is that considerable differences occur in the way the concept is used in the documents compared to the way it is used and ascribed meaning by the educators in teacher education. The article recommends to promote discussions about the student teachers’ perceptions of coherence in ways that address the complexity of both teacher education and teaching in schools

Vidensflow: Hvordan kan forbindelserne mellem forskning og uddannelse i professionshøjskoler begribes?

In 2013, the University Colleges in Denmark was legalized as research-based institutions and the nexus between research and education is therefore rather unexplored in the area of universities of applied science. The demand of being research based educations combined with limited research based knowledge of nexus between research and education call upon development of clear concepts. The study show that the arena of education is mainly positioned as recipient in relation to the arena of research and the article argues for a mutual optic on the nexus. In the research literature there is a lack of systematic conceptualization of the different types of connections between the two areas. The article suggests a three-piece typology: a materialized, an actor and an organizational connection

”Kompetenceløft i undervisningsfagene” - sætter det sig spor i skolens praksis?

Baseret på survey, observationer og interviews er det undersøgt, hvordan ”Kompetenceløft i undervisningen” (KiU) sætter sig spor i skolens praksis og hvilke faktorer der har betydning for dette. Resultaterne viser en mangfoldighed af sporsætning. Uddannelsen sætter sig spor såvel i som uden for undervisningen i skolen og det sker i form af både didaktiske kompetencer og faglig selvtillid i kommunikationen med kolleger, elever og forældre. Der er forskelle mellem fag, men ikke signifikante forskelle i udbytte mellem kommunale modeller, i.e. KOPRA i Aarhus kommune. De fleste deltagere refererer til indre-styret motivation. Hæmmende faktorer har været manglende tid, og den afsluttende prøve nævnes også. Her er forskelle mellem KOPRA og ikke-KOPRA. KOPRA lærere nævner i højere grad kollegers anerkendelse som fremmende, men også forventning om kollegasamarbejde som hæmmende, hvis rammerne har manglet lokalt. Resultaterne perspektiveres i en model med KiU didaktiske opmærksomhedsfelter og forslag om mulige didaktiseringsstrategier

Entanglement quantification from incomplete measurements: Applications using photon-number-resolving weak homodyne detectors

The certificate of success for a number of important quantum information processing protocols, such as entanglement distillation, is based on the difference in the entanglement content of the quantum states before and after the protocol. In such cases, effective bounds need to be placed on the entanglement of non-local states consistent with statistics obtained from local measurements. In this work, we study numerically the ability of a novel type of homodyne detector which combines phase sensitivity and photon-number resolution to set accurate bounds on the entanglement content of two-mode quadrature squeezed states without the need for full state tomography. We show that it is possible to set tight lower bounds on the entanglement of a family of two-mode degaussified states using only a few measurements. This presents a significant improvement over the resource requirements for the experimental demonstration of continuous-variable entanglement distillation, which traditionally relies on full quantum state tomography.Comment: 18 pages, 6 figure

Classification of death causes after transplantation (CLASS):Evaluation of methodology and initial results

Correct classification of death causes is an important component of transplant trials.We aimed to develop and validate a system to classify causes of death in hematopoietic stem cell (HSCT) and solid organ (SOT) transplant recipients.Case record forms (CRF) of fatal cases were completed, including investigator-designated cause of death. Deaths occurring in 2010 to 2013 were used for derivation; and were validated by deaths occurring in 2013 to 2015. Underlying cause of death (referred to as recorded underlying cause) was determined through a central adjudication process involving 2 external reviewers, and subsequently compared with the Danish National Death Cause Registry.Three hundred eighty-eight recipients died 2010 to 2015 (196 [51%] SOT and 192 [49%] HSCT). The main recorded underlying causes of death among SOT and HSCT were classified as cancer (20%, 48%), graft rejection/failure/graft-versus-host-disease (35%, 28%), and infections (20%, 11%). Kappa between the investigator-designated and the recorded underlying cause of death was 0.74 (95% CI 0.69-0.80) in derivation and comparable in the validation cohort. Death causes were concordant with the Danish National Death Cause Registry in 37.2% (95% CI 31.5-42.9) and 38.4% (95% CI 28.8-48.0) in the derivation and validation cohorts, respectively.We developed and validated a method to systematically and reliably classify the underlying cause of death among transplant recipients. There was a high degree of discordance between this classification and that in the Danish National Death Cause Registry

Living alone is a risk factor for mortality in men but not women from the general population: a prospective cohort study

During the past decades a rising trend of living alone can be observed in the population especially in urban areas. Living alone is considered a psychosocial risk factor. We studied the relationship between living alone, cardiovascular risk factors and mortality. We analysed data from the population-based MONICA/KORA cohort study including 3596 men and 3420 women of at least one of three surveys carried out between 1984 and 1995 in the region of Augsburg, Germany. They were between 45 and 74 years old and were followed-up until 31 December 2002. During follow-up 811 men and 388 women died. Cox proportional hazards analysis was used to examine the association between living alone and mortality
