A course evaluation is a survey sent out to all students after they have completed a course at Uppsala University. The objective of this survey is to allow the students to state their opinions of the course and give the course coordinatior an apprehension of how the students have perceived the course. This information can later be used to take necessary measures to increase the quality of the next instance of the course. The course coordinator compiles the students' opinions from the course evaluation together with their own opinions and analysis about the course instance into a course report. All the course reports are uploaded to a website called Medarbetarportalen but they are stored in an unorganized directory structure and there is no way of searching for a specific report or other information about a course instance. Moreover, students are only able to read the course report from an instance of a course that they participated in.  Making this information easily accessible would be beneficial for the evolvement of a better education. We have therefore created a portal which makes it possible for students, course coordinators, director of studies, education prefects and other employees at Uppsala University to easily find information regarding earlier course instances. This information consists of course reports, course evaluations, avarage grades as well as the number of students registered on the course instance. The portal also offers an easy way for course coordinators to write course reports.  Both through user testing and continous communication with employees at the IT institution the system has gotten positive feedback and the result was a working and useful portal with good requisites for further developement and launch by Uppsala University. / En kursvärdering är en enkät som skickas ut till alla studenter efter att de genomfört ett kurstillfälle på Uppsala universitet. Syftet med denna enkät är att ge studenterna en chans att tycka till om kursen och ge kursansvarig en uppfattning om hur studenterna har upplevt kursen för att sedan kunna använda detta som underlag för att vidta åtgärder till nästa kurstillfälle och på så sätt förbättra utbildningen. Kursansvarige sammanställer sedan kursvärderingen tillsammans med vilka åtgärder som ska göras inför nästa kurstillfälle till en kursrapport. Problemet är att studenter och anställda på Uppsala universitet inte lätt kan söka rätt på varken kursrapporter, kursvärderingar eller reslutat från olika kurstillfällen. Alla kursrapporter laddas upp på en hemsida som heter Medarbetarportlalen men där ligger de i en oorganiserad katalogstruktur och det är itne möjligt att söka rätt på en specifik rapport eller annan information om ett visst kurstillfälle. Dessutom har studenten endast möjlighet att läsa kursrapporter från kurstillfällen som de själva har deltagit på. Att göra denna information lättillgänglig är fördelaktigt för utvecklingen av en bättre utbildning. Vi har därför skapat en portal som gör det möjligt för studenter, kursansvariga, studierektorer, utbildningsprefekter och andra anställda på Uppsala universitet att söka rätt på information om tidigare kurstillfällen. Denna information består av kursrapporter, kursvärderingar, genomsnittsbetyg samt antal studenter på kurstillfället. Portalen gör det även möjligt för kursansvarig att skriva kursrapporter. Både genom användartester och kontinuerlig kommunikation med anställda på IT-institutionen har systemet fått positivt gensvar och resultatet blev en fungerande och användbar plattform med goda förutsättningar för vidareutveckling och lansering av Uppsala universitet.

Goals: The purpose of our study was to evaluate trends of hospitalization, acute kidney injury (AKI) and mortality in cirrhotic patients with spontaneous bacterial peritonitis (SBP). Background: SBP is a frequent bacterial infection in cirrhotic patients leading to increased morbidity and mortality. Materials and Methods: A total of 4,840,643 patients hospitalized with cirrhosis from 2005 to 2014 were identified using the Nationwide Inpatient Sample database, of which 115,359 (2.4%) had SBP. We examined annual trends and used multivariable mixed-effects logistic regression analyses to obtain adjusted odds ratios by accounting for hospital level and patient level variables. Results: We identified a striking increase in hospitalizations for SBP in cirrhotic patients (0.45% to 3.12%) and AKI in SBP patients (25.6% to 46.7%) from 2005 to 2014. Inpatient mortality decreased over the study period in patients with SBP (19.1% to 16.1%) and in patients with SBP plus AKI (40.9% to 27.6%). Patients with SBP had a higher inpatient mortality rate than those without SBP [15.5% vs. 6%, adjusted odd ratio (aOR): 2.02, P<0.001]. AKI was 2-fold more prevalent in cirrhotics with SBP than those without SBP (42.8% vs. 17.2%, aOR: 1.91, P<0.001) and concomitant AKI was associated with a 6-fold mortality increase (aOR: 5.84, P<0.001). Cirrhotic patients with SBP had higher hospitalization costs and longer length of stays than patients without SBP. Conclusions: Despite a higher hospitalization rate and prevalence of concomitant AKI, mortality in patients with SBP decreased during the study period. SBP is associated with high likelihood of development of AKI, which in turn, increases mortality.

Flurnamen sind die Bezeichnungen für Wälder, Felder, Wiesen, Berge, Gewässer und alle anderen natürlichen oder durch den Menschen beeinflussten Geländegegebenheiten, an denen sich der Mensch in der Landschaft orientiert. Sie sind gekennzeichnet durch einen engen Kommunikationsradius und eine geringe Stabilität, da sich in ihnen Veränderungen in der Gesellschaft und in den von dieser bedingten örtlichen Gegebenheiten oftmals zeitnah widerspiegeln. Als Bestandteil regionaler Identität dienen sie der Identifikation mit der den Menschen umgebenden Kulturlandschaft; sie sind sprachliche Relikte und wertvolle historische Zeugnisse einer Region. Diese zu erheben und auszuwerten, ist das Ziel einer über 100-jährigen Flurnamenforschung in Thüringen. Die gesammelten Belege liegen in unterschiedlichen Qualitäten vor, der weitaus größte Teil findet sich in Form eines Zettelkatalogs in der Sammlung des Thüringischen Flurnamenarchivs der Friedrich-Schiller-Universität Jena (FSU). Dieses ist jedoch nicht der Öffentlichkeit zugänglich und auch von der Forschung nur unter schwierigen Bedingungen nutzbar. Mit der Digitalisierung des Bestandes und dem Aufbau des Thüringer Flurnamenportals seit Juni 2019 ändert sich dies. Der Beitrag stellt den Thüringer Ansatz zur digitalen Aufbereitung des regionalen Flurnamenschatzes und zur bürgerwissenschaftlichen Flurnamenforschung vor. / Field names are used to designate uninhabited areas in a local district such as forests, fields, meadows, mountains, rivers and lakes and all the other natural or human-influenced features of a landscape that people use to orient themselves there. As such, they are a part of people’s regional identity and serve to establish their identification with the surrounding cultural landscape ; they are linguistic relics and provide important historical testimony of a region. Field names in Thuringia have been collected and evaluated in more than 100 years of research conducted there. Since 2019 the holdings of the Thuringian Archive of Field Names have begun to be digitized, and a Thuringian Field Names Portal is being developed. The article is a report on work in progress and presents the Thuringian approach to the digital processing of the region’s field name heritage and to field name research based on citizen science.

This study examined the effects of gamification, i.e. (what makes games challenging, engaging and fun), and its effects on speed and accuracy on an interdependent paper sorting task. Undergraduate students (N=42) at the University of Central Florida participated by working interdependently in groups to sort numbered pieces of paper into piles before and after either playing video games or doing back-to-back drawing(basic team building exercises). It was hypothesized that participants who played video games would sort pieces of paper into the piles faster and more accurate than those who did back-to-back team exercises. Results showed that playing video games was not better than doing basic team exercises, but that the two tasks were relatively equal. Although groups were formed and dissolved quickly, there was improvement between the pre and posttests. While the experiment did not yield significant results, it is possible that using different video games or different interdependent tasks could foster increases in speed and accuracy compared to back-to-back drawing.
