Seriepositionseffekter och recency-kvoten har visat potential som kliniska verktyg riktade mot neurokognitiva störningar, de har dock förblivit outforskade i Claeson-Dahls Test för inlärning och minne (CDT). Den aktuella studien syftade att fylla kunskapsluckan, vilket gjordes genom naturalistiskt insamlade data (N = 110) från ett projekt avsett att uppdatera CDT:s normer. Jag hypotiserade förekomSerial positioning effects and the derived recency ratio has shown increasing promise as clinical tools for evaluating neurocognitive disorders. These measures have remained unexplored in Claeson-Dahl’s Test for verbal learning and retention (CDT). To correct this, the present study used naturalistic sample data (N = 110) from a project intended to update CDT’s norms. I hypothesized the prevalence

AI tar oss ett steg närmare en lösning till gåtan bakom flexibla proteiner Proteiner är byggstenarna till det mikroskopiska maskineri som utför i stort sett alla biologiska processer i naturen. När vi vill utveckla läkemedel för att lösa problem som kan uppstå i maskineriet eller bekämpa angripande patogener är förståelse av proteiners 3-dimensionella struktur ovärderlig. Visualisering av proteinThe deep learning revolution has contributed to a great leap in protein structure prediction, but predicting the multiple conformational states that proteins can hold remains an open problem. This thesis approaches this problem through the use of MSA Transformer, a protein language model pre-trained on multiple sequence alignments, that has demonstrated the ability to learn protein properties such

Bakgrund: Menopaus är en naturlig del av kvinnors åldrande och infaller runt 40–60 års ålder. Upplevelsen av symtomens påverkan i kroppen under denna period är högst individuell. Kvantitativa studier visar att klimakteriet har påverkan på delaktighet i aktivitet men studierna visar inte hur kvinnor upplever klimakteriets påverkan. Syfte: Studiens syfte är att undersöka kvinnors upplevelse av delaIntroduction: Menopause is a natural part of women's aging and occurs in the age between 40–60. Symptoms experienced during this period, is highly individual. Quantitative studies show that menopause has an impact on participation in activity, but studies do not highlight how women experience that impact. Aim: The purpose of the study is to investigate women's experience of participation i
The editorial usage of stock images solves publishing challenges of illustrating news that are not connected to specific events. At the same time it contributes to an increasing vagueness and detachment between image content and the news story. This paper analyses the use of stock images in news journalism covering finance and the economy, specifically in the financial section of the Swedish daily

Borgholms castle on Öland is a medieval fortification built on the eastern border of today's Sweden. But when it was built around 800 years ago the borders, power structure and ownership over the Baltic sea were split between several powers. During the 12th and 13th century the Baltic sea contained many wars, pirates and crusades, and in the midst of it Borgholm castle was built. Thus the ques
This thesis is a study of the moral, medical, and socioeconomic arguments in favor of a racial hygienic sterilization legislation carried out in conservative, social democratic and socialist newspapers in Denmark from 1911-1923. While the sterilization legislation did not come into effect until 1933, the question was heavily discussed publicly in the preceding years. The public belief in omniscien
The Swedish National Council for Crime Prevention has in its safety survey from 2023 determined that 53% of Sweden's population are concerned about the criminal activity occurring in the society. Furthermore, studies also found that half of the students in grade 9 participated in at least one criminal activity within the last 12 months. Therefore, this study aimed to get a better understanding
The purpose of this paper was to gain an in-depth understanding of the phenomenon of “stay-at-home children” and how the personnel at a school explain their work with pupils who are “stay-at-home children”. We also aimed to explore the opportunities school staff have to prevent pupils from becoming “stay-at-home children” and how they collaborate as a team. This is a qualitative study involving fi
Syftet med studien är att analysera hur personalomsättningen inom en specifik avdelning i akutvården påverkar personalens upplevelser av samhörighet. Målet är att bilda en nyanserad förståelse för de faktorer som påverkar samhörigheter och identifiera eventuella utmaningar som kan uppstå på grund av den höga personalomsättningen. Arbetet är en kvalitativ studie där vi utfört totalt sju semistruktu
Trots att exponering- och responsprevention (ERP) är en effektiv behandling för patienter med tvångssyndrom (eng: obsessive-compulsive disorder; OCD), blir inte alla hjälpta. Medan många författare har intresserat sig för demografiska och kliniska faktorers betydelse för behandlingsutfall, är det få studier som har undersökt hur processer som uppstår under behandling (t.ex. förändring i motivationExposure and response prevention (ERP) is an effective treatment for obsessive-compulsive disorder (OCD), but not everyone benefits. While many authors have explored the contribution of demographic and clinical factors in relation to treatment outcome, few studies have investigated how processes that occur during the course of treatment (e.g., changes in motivation) relate to treatment outcome. Th
In recent years, the threat against establishments in Sweden's public environment has increased, especially towards religious congregations, streets, squares, and other densely populated areas. These attacks tend to result in incidents involving ongoing lethal violence. The report examines how different establishments approach warning alarm systems and drills for threats involving ongoing leth
The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. I will first simulate the influence, that the other planets have on
