This dissertation reports on an investigation into how digital tools are used, negotiated and given meaning in Swedish pre-school teacher education. The overall aim has been to create a deeper understanding of how students’ information literacies are enacted when digital tools are used and appropriated in the daily life at a pre-school teacher education, in relation to conceptions of the digitalis
Commenting on Eco's papers about fakes, I claimed that what is meant by a fake depends on what is taken to be the original, and this, in turn, revolves around the relation between type and token. As observed by Prieto and Grice, a sign, apart from the content it conveys, also carries a message informing us that it is a sign. The scare crow is a sign to the addresser, but not, ideally, to the addre
Si la traducción es un acto de transacción de sentidos, la semiótica debeser capaz de definir su especificidad en relación con otros actos semióticos. En lugar de eso, siguiendo a las sugerencias de Roman Jakobson, de la escuela de Tartú y, de forma implícita, de Charles Sanders Peirce, la noción de traducción ha sido generalizada para cubrir más o menos todas las operaciones que se pueden llevar
Previous work indicates that physical robots elicit more favorable social responses than virtual agents. These effects have been attributed to the physical embodiment. However, a recent meta-analysis by Li [1] suggests that the benefits of robots are due to physical presence rather than physical embodiment. To further explore the importance of presence we conducted a pilot study investigating the
Introduction: Long-term oxygen therapy (LTOT) improves survival and may reduce hospital admissions in patients with chronic obstructive pulmonary disease (COPD) and severe hypoxemia, but the impact of daily duration of LTOT on hospitalization rate is unknown. We aimed to estimate the association between the daily duration of LTOT (24 vs 15 h/d) and hospital admissions in patients with LTOT due to
Antiepileptic drugs (AEDs) are effective against seizures, but their use is often limited by adverse effects, among them psychiatric and behavioral ones including aggressive behavior (AB). Knowledge of the incidence, risk factors, and the underlying mechanisms of AB induced by AEDs may help to facilitate management and reduce the risk of such side effects. The exact incidence of AB as an adverse e
To investigate the mechanical behaviour of timber-concrete composite (TCC) beams strengthened with carbon fibre-reinforced polymer (CFRP), one TCC beam without CFRP and three TCC beams with different thickness of CFRP were tested under four point bending. During the loading process, the deformation development and failure mode of the composite beams were observed. The strain distribution at mid-sp
Background and Objective: The possible adverse or positive effects of levothyroxine treatment among patients with atrial fibrillation have been debated. Atrial fibrillation, levothyroxine treatment, and dementia are common among older adults, yet little is known about the effects of levothyroxine on the development of dementia. Methods: The study population included all adults (n = 12,057) aged ≥
Tau is an axonal microtubule-binding protein. Tau pathology in brain and increased tau concentration in the cerebrospinal fluid (CSF) are hallmarks of Alzheimer’s disease (AD). Most of tau in CSF is present as fragments. We immunoprecipitated tau from CSF and identified several endogenous peptides ending at amino acid (aa) 123 or 224 using high-resolution mass spectrometry. We raised neo-epitope-s
The Large Gain Theorem is an input-output stability result with intriguing applications in the field of control systems. This paper aims to increase understanding and appreciation of the Large Gain Theorem by presenting an interpretation of it for linear time-invariant systems using the well-known Nyquist stability criterion and illustrative examples of its use. The Large Gain Theorem is complemen
