Background: Previous research shows that critical constructive feedback, that scaffolds students to improve on tasks, often remains untapped. The paper’s aim is to illuminate at what stages students provided with such feedback drop out of feedback processing. Methods: In our model, students can drop out at any of five stages of feedback processing: (1) noticing, (2) decoding, (3) making sense, (4)
Crowd models can be used for the simulation of people movement in the built environment. Crowd model outputs have been used for evaluating safety and comfort of pedestrians, inform crowd management and perform forensic investigations. Microscopic crowd models allow the representation of each person and the obtainment of information concerning their location over time and interactions with the phys
We present an approach for the estimation of ore processing residue volumes in historical mine waste dumps by the use of different geophysical methods in combination with mineralogical investigations. The stamp mill dump in the Harz mountains, Germany was examined with the methods electrical resistivity tomography (ERT), ground penetrating radar (GPR) and spectral induced polarization (SIP) flanke
The ability of new neurons to promote repair of brain circuitry depends on their capacity to re-establish afferent and efferent connections with the host. In this review article, we give an overview of past and current efforts to restore damaged connectivity in the adult mammalian brain using implants of fetal neuroblasts or stem cell-derived neuronal precursors, with a focus on strategies aimed t
Full-field transmission X-ray microscopy (TXM) is a well established technique, available at various synchrotron beamlines around the world as well as by laboratory benchtop devices. One of the major TXM challenges, due to its nanometre-scale resolution, is the overall instrument stability during the acquisition of the series of tomographic projections. The ability to correct for vertical and hori
There is a large financial incentive to minimise operations and maintenance (O&M) costs for offshore wind power by optimising the maintenance plan. The integration of condition monitoring (CM) and structural health monitoring (SHM) may help realise this. There is limited work on the integration of both CM and SHM for offshore wind power or the use of imperfectly operating monitoring equipment.
The construction workflow of in-situ concrete frames in multi-storey residential buildings is highly complex and dynamic. Discrete-event simulation (DES) offers capabilities to model and analyse such complexity. Although DES has successfully been used by researchers in a wide range of construction-related applications there are not many examples demonstrating how different simulation outputs (time
Emergence agitation following anesthesia in children is not uncommon. It is, although generally self-limiting, associated with both patient and parents distress. We conducted a national survey around the management of behavioral and neurocognitive disturbances after surgery/anesthesia including a case scenario about a child at risk for emergence reaction. Premedication with clonidine or midazolam
Obesity is the main risk factor behind insulin resistance and type 2 diabetes. Still, the mechanism behind adipocyte dysfunction is not yet resolved. Recently, we reported that rapid actin remodeling correlates with adipose cell size changes after short-term overfeeding. Therefore, we hypothesized that the actin-driven myocardin-related transcription factor (MRTF-A) contributes to impaired mature
A modification to our previous simulation of breast anatomy is proposed to improve the quality of simulated x-ray projections images. The image quality is affected by the voxel size of the simulation. Large voxels can cause notable spatial quantization artifacts; small voxels extend the generation time and increase the memory requirements. An improvement in image quality is achievable without redu
Purpose: Digital breast tomosynthesis (DBT) is a promising breast cancer screening tool that has already begun making inroads into clinical practice. However, there is ongoing debate over how to quantitatively evaluate and optimize these systems, because different definitions of image quality can lead to different optimal design strategies. Powerful and accurate tools are desired to extend our und
Rationale and Objectives: Studies have demonstrated a relationship between mammographic parenchymal texture and breast cancer risk. Although promising, texture analysis in mammograms is limited by tissue superposition. Digital breast tomosynthesis (DBT) is a novel tomographic x-ray breast imaging modality that alleviates the effect of tissue superposition, offering superior parenchymal texture vis
Background: Stroke is one of the leading causes of death, and out of all stroke cases, 10-15% originate from a previously asymptomatic stenosis in the internal carotid artery. Aims: The aim of the study was to investigate whether dietary and lifestyle habits were associated with future risk of incident carotid artery disease (CAD). Methods: Baseline examinations on middle-aged individuals (n = 30,
Purpose: The aim of the present study was to analyze the long-term incidence of hip complications after external beam radiation therapy compared with age-matched controls from the general population. We also investigated whether there were any dose−response associations. Methods and materials: A total of 349 patients with prostate cancer treated to curative dose with external beam radiation therap
Background: Empowered women have improved decision-making capacity and can demand equal access to health services. Community-based interventions based on building women’s groups for awareness generation on maternal and child health (MCH) are the best and cost-effective approaches in improving their access to health services. The present study evaluated a community-based intervention aimed at impro
Structured reflective writing during clinical placement has been shown to be valuable for students’ learning and for their personal and professional development. The aim of this study was to examine clinical supervisors’ experiences of midwifery students’ daily written reflections on their practice at birthing units. A qualitative study was performed, and data were analysed using content analysis.
CHANGES resulting in altered antigenic properties of viruses nearly always occur on their surface and have been attributed to the substitution of residues directly involved in binding antibody. To investigate the mechanism of antigenic variation in foot-and-mouth disease virus (FMDV), variants that escape neutralization by a monoclonal antibody have been compared crystallographically and serologic
Background: The outcome in patients after surgery for acute type A aortic dissection without replacement of the part of the aorta containing the primary tear is undefined. Methods: Data of 1122 patients who underwent surgery for acute type A aortic dissection in 8 Nordic centers from January 2005 to December 2014 were retrospectively analyzed. The patients with primary tear location unfound, unkno
