Effects of intervention on self-efficacy and text quality in elementary school students’ narrative writing

Aim: Self-efficacy for writing is an important motivational factor and considered to predict writing performance. Self-efficacy for narrative writing has been sparsely studied, and few studies focus on the effects of writing intervention on self-efficacy. Additionally, there is a lack of validated measures of self-efficacy for elementary school students. In a previous study, we found that a traine

Tool–chip thermal conductance coefficient and heat flux in machining : Theory, model and experiment

This study proposes a technique for determining a tool–chip thermal conductance coefficient and heat flux in machining. The technique is based on solving an inverse heat transfer problem (IHTP). Because the IHTP is ill-posed, a priori information is required for its effective solution. To derive this information, substantial qualitative and quantitative analysis of a mixed boundary value problem f

Contemporary science as context for teaching nature of science : Teachers' development of popular science articles as a teaching resource

Most of the physics (as well as the other sciences) taught in school can be described as well-established or consensus science. This is the kind of science knowledge that was mostly developed over a century ago. The inclusion of contemporary science research in compulsory school science teaching could be justified from a variety of reasons: increasing students' interest and motivation; providing i

Imagination

Imagination is a human capacity that reproduces and transforms experiences and thoughts. The capacity is manifested in children’s pretend play and is an important part of adults’ ability to process the past, and to plan the future. A first step in the development of imagination is the ability to represent objects and events and to change these representations into alternatives to reality. For adap

The Socio-Legal Relevance of Artificial Intelligence

This article draws on socio-legal theory in relation to growing concerns over fairness, accountability and transparency of societally applied artificial intelligence (AI) and machine learning. The purpose is to contribute to a broad socio-legal orientation by describing legal and normative challenges posed by applied AI. To do so, the article first analyses a set of problematic cases, e.g. image rThis article draws on socio-legal theory in relation to growing concerns over fairness, accountability and transparency of societally applied artificial intelligence (AI) and machine learning.

Not just fuel : energy stores are correlated with immune function and oxidative damage in a long-distance migrant.

In many animals, catabolic and anabolic periods are temporally separated. Migratory birds alternate energy expenditure during flight with energy accumulation during stopover. The size of the energy stores at stopover affects the decision to resume migration and thus the temporal organization of migration. We now provide data suggesting that it is not only the size of the energy stores per se that

Retinofugal projections in the eel, Anguilla anguilla L. (Teleostei), visualized by the cobalt-filling technique

The retinofugal projections in the eel were studied by use of the cobalt-filling technique. The optic tract projects contralaterally to the hypothalamic optic nucleus, the anterior periventricular nucleus, the lateral geniculate nucleus, the dorsomedial optic nucleus, four pretectal recipient areas, the optic tectum, and the tegmentum. Small ipsilateral projections were demonstrated in the hypotha

Lars E O Svenssons drama i fyra akter.

Lars E O Svenssons kritik mot att Riksbanken inte har uppnått inflationsmålet har lett till en infekterad debatt mellan ledande ekonomer. Vår genomgång av hans kalkyler visar att de är bräckliga och missvisande, skriver ekonomiforskarna Lars Jonung och Fredrik N G Andersson.

Hypoxia with acidosis in extremely preterm born infants was not associated with an increased risk of death or impaired neurodevelopmental outcome at 6.5 years

Aim: It is not clear whether perinatal acidosis can predict poor outcomes in extremely preterm infants and we investigated associations between intrapartum hypoxia and mortality and neurodevelopmental outcomes. Methods: We used nationwide data on 705 infants from the Extremely Preterm Infants in Sweden Study, delivered at 22-26 weeks of gestation during 2004-2007. Comprehensive neurodevelopmental

Who should record surgical complications? Results from a third-party assessment of complications after radical cystectomy

Objective: In Sweden complications after radical cystectomy have been reported to the nationwide population-based Swedish Cystectomy Registry since 2011. Here, validation of the reporting was assessed in two healthcare regions. Materials and methods: Complications were ascertained from patient records by a third party not involved in the care delivered to 429 randomly selected patients from 949 wh

Divide and rule Cyprus? Decolonisation as process

Instances of decolonisation can be considered processes featuring complicated interactions that are both path-depended and open-ended. This perspective contrasts with reductionist epistemologies, particularly economistic ones. Viewing the decolonisation of Cyprus in processual terms, this article argues that the process at hand was crucially shaped by the colonial strategy of divide-and-rule and t

Multi-Port Element for Grating Lobe Suppression in Sparse VHF Phased Array Radars

A multi-port element approach, engineered to address practical design challenges of very high frequency (VHF) phased array radar systems, is presented in this communication. A cornerstone of the antenna element design is its simplicity, which counteracts the mobility issues of physically large and unavoidably bulky ground-based VHF radar systems. The multi-port element introduces a third dimension

Soft particles in an electric field-a zero average contrast study

We report on the structural properties of ionic microgel particles subjected to alternating electric fields, using small-angle neutron scattering. The experiments were performed under so-called zero average contrast conditions, which cancel the structure factor contribution to the scattered intensity, allowing us to obtain direct information on the single particle size and structure as particles a

Mental Health Nurses’ Experiences of Risk Assessments for Care Planning in Forensic Psychiatry

The risk of patients committing violence implies major challenges throughout the care process in forensic psychiatry and brings risk assessments to the fore. The aim was to explore nurses’ experiences of risk assessments for their care planning and risk management in forensic psychiatry. Data were collected through focus groups with 15 nurses. The qualitative content analysis followed a deductive
