A Suggested Seminar in Student Rights

The decade now passing away from us has bubbled with significant change in law school curricula, especially from the heat of recent developments in constitutional law

KCCA Feature Selection for fMRI Analysis

We use Kernel Canonical Correlation Analysis (KCCA) to infer brain activity in functional MRI by learning a semantic representation of fMRI brain scans and their associated activity signal. The semantic space provides a common representation and enables a comparison between the fMRI and the activity signal. We compare the approach against Canonical Correlation Analysis (CCA) and the more commonly used Ordinary Correlation Analysis (OCA) by localising “activity” on a simulated null data set. We also compare performance of the methods on the localisation of brain regions which control finger movement and regions that are involved in mental calculation. Finally we present an approach to reconstruct an activity signal from an “unknown” testing-set fMRI scans. This is used to validate the learnt semantics as non-trivial

Kontinuerlig mätning av blodsocker på intensivvårdspatienter, ett sätt att öka patientsäkerheten?

Bakgrund Som intensivvårdssjuksköterska är man skyldig att uppfylla uppdraget att leverera professionell och högteknologisk vård samtidigt som man tar hänsyn till det specifika lidande som intensivvårdspatienter utsätts för. Ett vanligt tillstånd bland intensivvårdspatienter är hyperglykemi och insulinresistens. Förbättrade metoder för blodsockermätning i kombination med insulinbehandling är associerat med bättre återhämtning och positiva utfallsmått hos alla grupper av intensivvårdspatienter. Med hänvisning till Orems teori om egenvårdsbrist, patientlagen och patientsäkerhetslagen har vi strävat efter att öka patientsäkerheten genom kunskapsinhämtning om noggranna och effektiva metoder för blodsockermätning inom intensivvård. Om beslutsfattandet för sjuksköterskor förbättras genom säkrare omvårdnadsmetoder kan intensivvårdspatienternas egenvårdskapacitet rehabiliteras. Syfte Att undersöka och klargöra om en kontinuerlig mätmetod för blodsocker är patientsäkert för intensivvårdspatienter.  Metod En litteraturstudie med kvantitativ ansats om kontinuerlig mätning av glukos hos kritiskt sjuka patienter har genomförts. Tretton artiklar har bearbetats och analyserats systematiskt med hjälp av granskningsmall för kvantitativ forskning. Sökningen genomfördes i PubMeds databas med publicering ej äldre än 10 år. Resultat Av 13 granskade artiklar visade 11 att kontinuerlig mätning av blodsocker gav korrekta och tillförlitliga glukosvärden hos kritiskt sjuka patienter. Alla tre studier som beskrev mikrodialys som en kontinuerlig glukosmätningsmetod ansåg metoden som tillförlitlig. Subkutan kontinuerlig glukosmätning var lika pålitlig som standardmätning i tre studier. I två studier ifrågasattes tillförlitligheten. Slutsats Studien visar på att kontinuerlig mätning av blodsocker är en lovande metod men med bristande evidens. Ytterligare forskning bör genomföras för att undersöka vilken metod som passar den specifika subgrupp av intensivvårdspatienter, eller helst passar alla intensivvårdspatienter.Background                                                                                                                                    As a critical care nurse, one is obliged to fulfill the mission of delivering professional and high-tech care, whilst calculating the specific suffering that intensive care patients are exposed to. A common condition in critical care populations is hyperglycemia and insulin resistance. Enhanced methods of glucose measuring combined with insulin treatment, are associated with better recovery and outcome, in all intensive care populations. With reference to Orem's theory of self-care, the Patient Act and the Patient Safety Act, we have endeavored to increase patient safety through knowledge acquisition on accurate and effective methods for glucose measurement in intensive care. If decision-making for nurses can be improved by safer nursing methods, the intensive care patients' self-care capacity can be rehabilitated. Aim To investigate whether continuous glucose monitoring is a reliable method for glucose control in the intensive care unit. Method An overview of scientific literature, concerning continuous monitoring of glucose in critically ill patients has been conducted. Thirteen peer-reviewed articles have been processed and analyzed systematically using a review template for quantitative research. The search was performed in Pub-Meds database and the articles were published within the last 10 years. Result Out of 13 peer reviewed articles 11 showed that continuous monitoring of glucose gave accurate and reliable glucose levels in critically ill patients. All three studies describing micro-dialysis, as a continuous method of measuring glucose, were in favor of its reliability. Subcutaneous continuous glucose monitoring was as reliable as standard measurements in three studies. In two studies the reliability was questioned.  Conclusion Continuously monitored blood glucose is a promising method but lacks evidence. Further research should be carried out, to explore which method suits which specific critical care patient population, or preferably, suits all intensive care patients.

Uncertainty in white matter fiber tractography

Abstract. In this work we address the uncertainty associated with fiber paths obtained in white matter fiber tractography. This uncertainty, which arises for example from noise and partial volume effects, is quantified using a Bayesian modeling framework. The theory for estimating the probability of a connection between two areas in the brain is presented, and a new model of the local water diffusion profile is introduced. We also provide a theorem that facilitates the estimation of the parameters in this diffusion model, making the presented method simple to implement.

The Dark Patterns of Battle Passes : Investigating player attitudes to a growing type of microtransaction

In recent years, many PC and console video games have seen a shift towards live service models as a means of generating recurring revenue through in-game purchases called microtransactions. Microtransactions have been linked to the concept of dark patterns—design patterns that favour the service at the expense of the end user—due to their possible negative impact on the user experience. One widespread yet poorly studied microtransaction is the battle pass, particularly from a player perspective. In order to investigate playerattitudes to dark patterns found in battle passes, we conducted two studies, by looking at battle passes found in 19 games, and by carrying out a series of discussion workshops, to identify dark pattern commonalities in battle passes, and to find out how players perceive and experience dark patterns in battle passes, respectively. Data was analysed by means of reflexive thematic analysis in both studies. The results show that battle passes attempt to drive increased player engagement and spending in a number of ways, and further that players have complex—and often contradictory—relationships to battle passes
