Towards an efficient use of infrastructure and the built environment : Essays in transport and housing economics

Avhandlingen består av fyra artiklar som alla kretsar kring hur ett effektivt nyttjande av infrastruktur kan uppnås. Tre av artiklarna berör externaliteter i transportsektorn medan den fjärde artikeln rör bostadsmarknaden och hur en skattereform påverkade äldre småhusägares flyttbeteende. Externaliteter uppstår när de beslut som en person (eller företag) tar har effekter även för andra och detta iAll four papers in the thesis share a common theme: how to achieve an efficient use of infrastructure and the built environment. In the presence of externalities, pricing according to the (short-run) marginal cost is one answer on how this can be achieved and the first two papers estimates parts of the marginal cost of traffic. Paper I examines the effect of road and railway noise on property pric

Evaluation of deep geothermal exploration drillings in the crystalline basement of the Fennoscandian Shield Border Zone in south Sweden

The 3.1- and 3.7-km-deep FFC-1 and DGE-1 geothermal explorations wells drilled into the Precambrian crystalline basement on the southern margin of the Fennoscandian Shield are evaluated regarding experiences from drilling, geological conditions, and thermal properties. Both wells penetrate an approximately 2-km-thick succession of sedimentary strata before entering the crystalline basement, domina

A thermodynamically consistent modelling framework for strongly time-dependent bainitic phase transitions

In this work, a thermodynamically consistent constitutive framework is introduced that is capable of reproducing the significant time-dependent behaviour of austenite-to-bainite phase transformations. In particular, the aim is to incorporate the effect of these diffusion-controlled processes by plasticity-like evolution equations instead of incorporating related global diffusion equations. To this

Exploring the combined use of solicited diaries and photography by older patients in their process of self-care with medication packaging

Design has the potential to include or exclude people, depending on how user needs are translated into products. Design exclusion has been vast in design for health care. Medication packaging design is a common example. It does a good job of protecting the product but can result in creating difficulties when used, especially for those who are older. Research in this area lacks an inclusive and use

Introduction : Mobile socialities

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book focuses on a collective of international scholars who are researching at the intersections of media, mobility and sociality. It explores the divergent vantage points of the interplay between mobilities and socialities, analysing material conditions, situated contexts and the ascri

Body Text : Typografi och litteraturens kropp

Artikeln behandlar typografins roll i relationen mellan text och läsare med utgångspunkt i bland annat bibliografisk teori och Jean-Luc Nancys fenomenologiska tankar om skrift och läsande. I fokus för artikeln står frågan: Kan vi förstå boken med sin typograferade text som litteraturens kropp?In one of his fragments, Georg Christoph Lichtenberg explains that German books printed with roman type, instead of the then default gothic type, always give him a feeling that he needs to translate them – evidence, he says, of “the degree to which our concepts are dependent on these signs”. The article elaborates on this thought. It explores the relation between literature, text (abstract and mat

Tau-related grey matter network breakdown across the Alzheimer’s disease continuum

Background: Changes in grey matter covariance networks have been reported in preclinical and clinical stages of Alzheimer’s disease (AD) and have been associated with amyloid-β (Aβ) deposition and cognitive decline. However, the role of tau pathology on grey matter networks remains unclear. Based on previously reported associations between tau pathology, synaptic density and brain structural measu

Male partners’ participation in birth preparedness and complication readiness in low- and middle-income countries : a systematic review and meta-analysis

Background: Maternal and neonatal health outcomes remain a challenge in low- and middle-income countries (LMICs) despite priority given to involving male partners in birth preparedness and complication readiness (BPCR). Men in LMICs often determine women’s access to and affordability of health services. This systematic review and meta-analysis determined the pooled magnitude of male partner’s part

The potential role of T2*-weighted multi-echo data image combination as an imaging marker for intraplaque hemorrhage in carotid plaque imaging

Background: Carotid atherosclerotic plaques with intraplaque hemorrhage (IPH) are associated with elevated stroke risk. IPH is predominantly imaged based on paramagnetic properties of the upstream hemoglobin degradation product methemoglobin. This is an explorative observational study to test the feasibility of a spoiled gradient echo based T2* weighted MRI sequence (3D MEDIC) for carotid plaque i

Involvement of professionals in research : knowledge integration, development of practice, and challenges: a group concept mapping study

Background: Research and practice are often considered as two different worlds with different values, which causes a gap between them. Involving professionals such as practitioners, managers, decision-makers, and policy-makers in research on ageing and health might address the gap between research and practice, strengthen the healthcare system, and increase older people’s possibilities for healthy

Clinical outcomes of head and neck cancer patients who refuse curative therapy in pursuit of alternative medicine

Background: We investigated the alarming trend of curable head and neck cancer (HNC) patients forgoing conventional treatment to pursue alternative medicine (AM). Methods: A prospectively maintained database identified HNC patients with ≥12 weeks from diagnosis to treatment initiation between 2012 and 2017. Reasons for delay were categorized and clinical stages and outcomes of AM patients were ass

Association between bacterial finding, antibiotic treatment and clinical course in patients with pharyngotonsillitis : a registry-based study in primary healthcare in Sweden

Background: The role of non-group A streptococci and Fusobacterium necrophorum in pharyngotonsillitis has been disputed and few prospective studies have evaluated the effect of antibiotic treatment. This study uses registry data to investigate the relation between antibiotic prescription for pharyngotonsillitis in primary healthcare and return visits for pharyngotonsillitis, complications, and ton

Comparative analysis of signal models for microscopic fractional anisotropy estimation using q-space trajectory encoding

Microscopic diffusion anisotropy imaging using diffusion-weighted MRI and multidimensional diffusion encoding is a promising method for quantifying clinically and scientifically relevant microstructural properties of neural tissue. Several methods for estimating microscopic fractional anisotropy (µFA), a normalized measure of microscopic diffusion anisotropy, have been introduced but the differenc

Serum markers of brain injury can predict good neurological outcome after out-of-hospital cardiac arrest

Purpose: The majority of unconscious patients after cardiac arrest (CA) do not fulfill guideline criteria for a likely poor outcome, their prognosis is considered “indeterminate”. We compared brain injury markers in blood for prediction of good outcome and for identifying false positive predictions of poor outcome as recommended by guidelines. Methods: Retrospective analysis of prospectively colle

Workaway : Cultivating conviviality within mobility, sociality and daily living

This ethnographic research on ‘Workaway’ investigates new forms of mobility experiences, in between travel and migration, which are used by a plethora of types of people (both hosts and guests) with different motivations (learning new skills and experiences), needs, ambitions, dreams, as well as/or life-time crisis, and different types of problems (e.g. lack of finances, no opportunity or prospect

How does HIV testing modality impact the cascade of care among persons diagnosed with HIV in Ethiopia?

Background: Despite scaling up of HIV programmes in sub-Saharan Africa, many people living with HIV (PLHIV) are unaware of their HIV status. New testing modalities, such as community-based testing, can improve test uptake, but it is uncertain whether type of testing modality affects the subsequent cascade of HIV care. Objective: To compare linkage to care and antiretroviral treatment (ART) outcome

Latency-aware Radio Resource Allocation over Cloud RAN for Industry 4.0

The notion of Cloud RAN is taking a prominent role in narrative for the next generation wireless infrastructure. It is also seen as a mean to industrial communication systems. In order to provide reliable wireless connectivity for industrial deployments, by conventional means, the cloud infrastructure needs to be reliable and incur little latency, which however, is contradictory to the stochastic

Modification of EDC method for increased labeling efficiency and characterization of low-content protein in gum acacia using asymmetrical flow field-flow fractionation coupled with multiple detectors

1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) is widely used as a crosslinker for fluorescence labeling of protein in the fields of biochemistry and food analysis. Many natural polysaccharides often contain some proteins or peptides that are very low in content but play a vital role in their biological function as well as technical applications. Determination of these low-content proteinace
