Very Early Life Risk Factors for Developing Dementia : Evidence from full population registers

OBJECTIVES: Very early-life conditions are recognized as critical for healthy brain development. This study assesses early-life risk factors for developing dementia. In the absence of historical medical birth records, we leverage an alternative full population approach using demographic characteristics obtained from administrative data to derive proxy indicators for birth complications and unfavor

Oxidative stress-related genetic variation and antioxidant vitamin intake in intact and ruptured abdominal aortic aneurysm : a Swedish population-based retrospective cohort study

AIMS: The aim of this study is to investigate how genetic variations in genes related to oxidative stress, intake of antioxidant vitamins, and any potential interactions between these factors affect the incidence of intact abdominal aortic aneurysm (AAA) and its rupture (rAAA), accounting for sex differences where possible.METHODS AND RESULTS: The present retrospective cohort study (n = 25 252) us

Klassriket Klasskunskaper i den svenska partipolitiska sfären, 1911-1940

This article investigates the creation and circulation of class knowledge among Sweden's political parties as Swedish representative democracy took shape, 1911-1940. When the expanded franchise for men was introduced in the general election of 1911, the National Statistics Bureau (SCB) was tasked with categorising voters to measure the effects of the reform. They created a taxonomy made up of thre

Class Divisions in Use : The Swedish Social Group Taxonomy as Difference Technology, 1911-1970

This article investigates an important but understudied phenomenon: the bureaucratic class division, which is analysed as a difference technology for envisioning, studying and managing the population. I examine a long-lived and widely spread taxonomy of the Swedish population into three social groups (Socialgrupper). Specifically, I look at how it influenced the production of statistics and knowle

Klass i begåvningsreservens tidevarv : Taxonomiska konflikter inom och genom svensk utbildningsforskning, ca 1945–1960

This article studies conceptualisations of social class in Swedish education research, c. 1945–1960. The article follows knowledge produced about talent and class in state commissions and in the newly expanded social sciences, and how it in turn was interpreted and used in political debates and in the media. I show that the taxonomy of the population in social groups (Socialgrupper) was key for co

Responsibility and Ambivalence

I use the concept of ambivalence—the state of being faced with a choice that cannot be resolved without sacrificing something of value—to approach five contemporary debates in the philosophy of moral responsibility: (1) psychopathy, (2) free will, (3) the emotion of guilt, (4) regret and indirect moral luck, and (5) moral demandingness. Rather than arguing for one theory or another, acknowledging

Quality Control in ECG-based Atrial Fibrillation Screening

This thesis comprises an introductory chapter and four papers related to quality control in ECG-based atrial fibrillation (AF) screening. Atrial fibrillation is a cardiac arrhythmia characterized by an irregular rhythm and constitutes a major risk factor for stroke. Anticoagulation therapy significantly reduces this risk, and therefore, AF screening is motivated. Atrial fibrillation screening is o

Gender (in)equality within the Swedish Armed Forces : Resistance and Functional Disinclination

Historically and traditionally, military work has been closely associated with men. However, the post-Cold War normalization process has brought about a transformation in both the Swedish Armed Forces themselves and the perception of the organization. Normative concerns, including gender equality, have gained significant prominence, compelling the armed forces to embark on various initiatives aime

CenTauR : Toward a universal scale and masks for standardizing tau imaging studies

INTRODUCTION: Recently, an increasing number of tau tracers have become available. There is a need to standardize quantitative tau measures across tracers, supporting a universal scale. We developed several cortical tau masks and applied them to generate a tau imaging universal scale. METHOD: One thousand forty-five participants underwent tau scans with either 18F-flortaucipir, 18F-MK6240, 18F-PI2

Genetic Moderation of the Association of β-Amyloid With Cognition and MRI Brain Structure in Alzheimer Disease

Background and Objectives: There is considerable heterogeneity in the association between increasing β-amyloid (Aβ) pathology and early cognitive dysfunction in preclinical Alzheimer disease (AD). At this stage, some individuals show no signs of cognitive dysfunction, while others show clear signs of decline. The factors explaining this heterogeneity are particularly important for understanding pr

Evaluation of single-fraction high dose FLASH radiotherapy in a cohort of canine oral cancer patients

Background: FLASH radiotherapy (RT) is a novel method for delivering ionizingradiation, which has been shown in preclinical studies to have a normal tissuesparing effect and to maintain anticancer efficacy as compared to conventionalRT. Treatment of head and neck tumors with conventional RT is commonlyassociated with severe toxicity, hence the normal tissue sparing effect of FLASHRT potentially ma

Rethinking bioeconomy innovation in sustainability transitions

Over the past two decades, a new research field dealing with “sustainability transitions” has emerged, analyzing the transformation of socio-technical systems towards more sustainable futures. While there is consensus on the crucial role of the bioeconomy in sustainability transitions research, we argue that the true potential of many bioeconomy innovations is not yet sufficiently recognized and a

Nature and Origin of Magnetic Lineations Within Valdivia Bank : Ocean Plateau Formation by Complex Seafloor Spreading

Valdivia Bank (VB) is a Late Cretaceous oceanic plateau formed by volcanism from the Tristan-Gough hotspot at the Mid-Atlantic Ridge (MAR). To better understand its origin and evolution, magnetic data were used to generate a magnetic anomaly grid, which was inverted to determine crustal magnetization. The magnetization model reveals quasi-linear polarity zones crossing the plateau and following ex

Experimenting with sustainability transformations: A study of Urban Living Labs in the food, water and energy nexus

Forskare och praktiker betonar alltmer vikten av tvärvetenskapliga och experimentella sätt att förstå och bemöta hållbarhetsutmaningar. Det finns en bred enighet om att samhället måste genomgå djupa och radikala förändringar, alltså omvandling (transformation). Men detta berorpå många dynamiska faktorer i lokala sammanhang. I denna avhandling utforskar jag hur man kan främja experimentella tvärvetScholars and practitioners increasingly emphasize the importance of transdisciplinary and experimental approaches for understanding and addressing sustainability challenges. While there is widespread agreement that human society must undergo deep and radical changes, or so-called transformation, how transformation happens depends on multiple and dynamic factors in local contexts. In this thesis, I

Vanadium oxide and a sharp onset of cold-trapping on a giant exoplanet

The abundance of refractory elements in giant planets can provide key insights into their formation histories1. Owing to the low temperatures of the Solar System giants, refractory elements condense below the cloud deck, limiting sensing capabilities to only highly volatile elements2. Recently, ultra-hot giant exoplanets have allowed for some refractory elements to be measured, showing abundances
