Background We need to better understand the frequency and predictors of opioid use disorder (OUD) after first opioid prescription (OP). Methods We followed 1 516 392 individuals from the Swedish population born 1980-2000, from 1 July 2007, until 31 Dec 2017. We examined putative risk predictors with univariable and multivariable Cox Models and the potential causal effects of predictors by propensi

Background: Assessing malignancy risk is important to choose appropriate management of ovarian tumors. We compared six algorithms to estimate the probabilities that an ovarian tumor is benign, borderline malignant, stage I primary invasive, stage II-IV primary invasive, or secondary metastatic. Methods: This retrospective cohort study used 5909 patients recruited from 1999 to 2012 for model develo

Employer branding in organizational human resources management is essential. Nevertheless, certain gaps persist within the realm of scientific research in this field, particularly in the exploration of novel concepts like employer brand personality appeal and its potential impact within the hospitality industry, which grapples with numerous human resources challenges. To fill this gap in knowledge

A search for new phenomena giving rise to pairs of opposite electrically charged muons with impact parameters in the millimeter range is presented, using 139 fb−1 of s=13 TeV pp collision data from the ATLAS detector at the LHC. The search targets the gap in coverage between existing searches targeting final states with leptons with large displacement and prompt leptons. No significant excess over

High spin states in 127La have been studied using the 32S(100Mo,p4n) reaction at a beam energy of 155 MeV. Gamma rays were detected using the EUROBALL III spectrometer. One of the side bands in 127La is observed to be populated to a spin of 83/2+. These data are compared with cranked Nilsson-Strutinski calculations which suggest that the structure is a smoothly terminating band, in valence space,

Background: Older adults have complex medical needs that causes increased use of resources at the emergency department (ED). The prevalence of non-specific complaint (NSC) as a chief-complaint in the ED is common among older adults and is not prioritized even though possibly having worse clinical outcome. The objective was to study hospital admission and mortality for older adults visiting the ED

The thesis presented here delves into why dwell time delays for commuter trains occur, with a specific focus on the impact of boarding and alighting passengers. The overarching aim is to develop knowledge of how time delays arise to identify and describe potential ways in which dwell time delays can be reduced. In addition to this, a secondary aim is to identify how dwell times can be studied on a

Background: Human breast cancer most frequently originates within a well-defined anatomical structure referred to as the terminal duct lobular unit (TDLU). This structure is endowed with its very own lobular fibroblasts representing one out of two steady-state fibroblast subtypes—the other being interlobular fibroblasts. While cancer-associated fibroblasts (CAFs) are increasingly appreciated as co

The DNA virus responsible for monkeypox, transmitted from animals to humans, exhibits two distinct genetic lineages in central and eastern Africa. Beyond the zoonotic transmission involving direct contact with the infected animals’ bodily fluids and blood, the spread of monkeypox can also occur through skin lesions and respiratory secretions among humans. Both monkeypox and chickenpox involve skin

In the rapidly evolving telecommunications industry, customer retention is crucial for maintaining profitability. This report investigates the performance of various machine learning models in predicting customer churn rates, which are integral to calculating Customer Lifetime Value (CLV). The focus is on a comparative analysis of several models including logistic regression, ridge regression, las

The current study aims to gain a deeper understanding of the various motivations for full-time work. Based on a set of semi-structured interviews (n=10) with working parents, it investigates the interaction between individual motivations and external factors, intentions and constraints and how it shapes work time preferences. The respondent's experiences and individual motives are used to exam

I Maj 2018 lanserade regeringen en strategi för Sveriges nationella skogsprogram. Som en viktig del av skogsprogrammets implementering initierar Länsstyrelserna nu regionala dialogprocesser för att jobba fram regionala skogsstrategier och handlingsplaner. Tidigare forskning visar att den svenska skogspolitiken hittills inte har lyckats hantera målkonflikterna mellan produktion och miljö. Därför viIn May 2018, a strategy for Sweden’s first National Forest Program was launched. As part of its implementation, County Administrative Boards are now initiating dialogue processes for drafting regional forest strategies and action plans. Previous research shows that Swedish forest policy has so far been unable to resolve the tensions between its production and environmental goals. I aim to investig

Misleading health information remains a central concern in medical sociology and public health due to its harmful effects on individuals and society. As health information-seeking increasingly shifts to digital platforms, Large Language Models (LLMs)—now commonly used as search engines—have intensified concerns about the spread of health misinformation. This study examines the potential for LLMs t

This study explores disaster communication for people experiencing homelessness in the capital region of Iceland. Traditional methods often fail to reach vulnerable populations who require alternative approaches effectively. The objective is to understand and improve disaster communication for people experiencing homelessness and identify possible improvements. To address this, in-depth interviews

Understanding how plants allocate time between the green-up and senescence phases within a growing season is critical for assessing vegetation responses to environmental change. This thesis investigates the spatiotemporal patterns of the time allocation fraction, defined as the ratio of green-up duration to senescence duration (RGS), across the Tibetan Plateau from 1982 to 2018. Phenological metri
