Photovoice is an increasingly popular research method across disciplines due to its flexibility and capacity for generating rich data. This article argues that while its practical virtues are abundant, the theoretical contributions of photovoice to qualitative research are just as important. We argue that photographs can act as boundary objects that enable collective sensemaking at multiple stages

What is the level of state capacity in developing countries today, and what have been its drivers over the past century? We construct a comprehensive new data set of tax and revenue collection for forty-six African polities from 1900 to 2015. Our data show that polities in Africa have been characterized by strong growth in fiscal capacity on average, but that substantial heterogeneity exists. The

Background: Inhomogeneous Magnetization Transfer (ihMT) is an emerging, uniquely myelin-specific magnetic resonance imaging (MRI) contrast. Current ihMT acquisitions utilise fast Gradient Echo sequences which are among the most acoustically noisy MRI sequences, reducing patient comfort during acquisition. We sought to address this by modifying a near silent MRI sequence to include ihMT contrast. M

Large amounts of germline sequencing data have recently become available and we sought to compare these results with population-based family history data. Family studies are able to describe aggregation of any defined cancers in families. The Swedish Family-Cancer Database is the largest of its kind in the world, covering the Swedish families through nearly a century with all cancers in family mem

Background: Patients with obesity have a higher risk of complications after total knee arthroplasty (TKA). We investigated the change in weight 1 and 2 years post-Bariatric Surgery (BS) in patients that had undergone both TKA and BS as well as the risk of revision after TKA based on if BS was performed before or after the TKA. Methods: Patients who had undergone BS within 2 years before or after T

Evidence of air pollution exposure, namely, ambient particulate matter (PM), during pregnancy and an increased risk of autism in children is growing; however, the unique PM sources that contribute to this association are currently unknown. The aim of the present study was to investigate local, source-specific ambient PM exposure during pregnancy and its associations with childhood autism, specific

Background: Molecular analyses have shown that tumours diagnosed as supratentorial primitive neuro-ectodermal tumours of the central nervous system (CNS-PNETs) in the past represent a heterogenous group of rare childhood tumours including high-grade gliomas (HGG), ependymomas, atypical teratoid/rhabdoid tumours (AT/RT), CNS neuroblastoma with forkhead box R2 (FOXR2) activation and embryonal tumour

The pediatric extra-cranial tumor neuroblastoma displays a low mutational burden while recurrent copy number alterations are present in most high-risk cases. Here, we identify SOX11 as a dependency transcription factor in adrenergic neuroblastoma based on recurrent chromosome 2p focal gains and amplifications, specific expression in the normal sympatho-adrenal lineage and adrenergic neuroblastoma,

Background: Early blight, caused by the necrotrophic fungal pathogen Alternaria solani, is an economically important disease affecting the tuber yield worldwide. The disease is mainly controlled by chemical plant protection agents. However, over-using these chemicals can lead to the evolution of resistant A. solani strains and is environmentally hazardous. Identifying genetic disease resistance fa

Assessing effects of climate change on agricultural systems and the potential for ecological intensification to increase food security in developing countries is essential to guide management, policy-making and future research. ‘Push-pull’ technology (PPT) is a poly-cropping design developed in eastern Africa that utilizes plant chemicals to mediate plant–insect interactions. PPT application yield

Prydlig, proper och välskött - så tycks den perfekta trädgården se ut. Men när den kortklippta gräsmattan växte fram som ideal bland Europas välbärgade var övriga naturen vildare. I en tid av artutrotning och klimatförändringar finns det större behov än någonsin av otjämjda trädgårdar, skrive råtta forskare och landskapsarkitekter.In an era of species extinction and climate change, we should abandon the well-trimmed lawn and let gardens grow wilder, writes Anna Persson and other researchers and landscape architects on DN Debatt.

In Sweden men account for most new HIV cases, and little is known about the peer support needs of people living with HIV in Sweden. This qualitative study explored how recently diagnosed men perceive and experience peer support in Sweden. Purposively sampled from HIV patient organizations and infectious disease clinics throughout Sweden, data was collected through in-depth individual interviews wi

Question: what do the following statistics have in common? The second-largest (and growing) source of climate pollution in Europe. The leading killer of children in both the US and Europe. A principal cause of stress-inducing noise pollution and life-shortening air pollution in European cities. A leading driver of the widening gap between rich and poor urban residents.Answer: the vehicles on our s

This letter presents a radio frequency front-end (RFFE) for 5G new radio (NR) receivers operating in frequency range 1 (FR1). The core of this RFFE is a synthetic fourth-order Q -enhanced RF filter employing gm -boosting, noise-canceling, capacitive cross-coupling, and forward body-biasing techniques to achieve 1.7 to 6.4 GHz operating range and 1% to 40% adjustable fractional bandwidth (FBW). The

It is rare to encounter a scientific fact that stirs widespread debate and distrust quite like the matter of climate change.Despite consensus among climate specialists about a theory that is supported by a mountain of facts from the physical, natural, and cultural sciences, the debate continues to be perpetrated by politicians, industrialists, academics, and armchair scientists.When governments re

Syftet med den här uppsatsen är att skapa förståelse för medlemmarnas kommunikativa funktioner i ett oetablerat politiskt parti och hur dessa funktioner kan användas i partiets arbete med strategisk kommunikation. Vidare behandlar uppsatsen hur oetablerade partier kan arbeta och ta tillvara på de interna resurserna för att nå sina mål. Uppsatsen grundar sig i en fallstudie av det politiska partietThe aim of this study is to obtain greater understanding of the different functions that members can contribute to an unestablished political party, and how these functions can be seen as assets in the organization’s work with strategic communication. Furthermore, this study investigates how unestablished parties can seize the underlying resources for its purpose to reach the organizational goals.

Bakgrund: Många barn upplever våld i sina familjer i vårt land. Upplevelser av våld kan leda till psykisk ohälsa. De anmälningar som görs till socialtjänsten utreds men leder sällan till insatser. Utredarna inom socialtjänsten är nyckelpersoner för att upptäcka dessa barn så att de får stöd, behandling och psykoterapi. Syfte: Att genom en enkätundersökning ta reda på vad utredare inom socialtjänstBackground: It is a fact that some children experience domestic violence in our country. The experience of violence is a severe threat towards children development and mental health. Further reports made to the social Services which lead to an actual social investigation of the child’s wellbeing seldom result in that proper treatment take place. The social service investigators are the key to pay

Ytplasmoner — Små, snabba och otroligt användbara Människan har länge förundrats över de vackra färgerna som klär glasrutorna i många medeltida katedraler, men det var dock inte förrän år 1957 då en forskare vid namn Rufus Richie först föreslog vad som gav upphov till detta fenomen. Det visade sig vara en egenskap hos ytplasmoner, som bl.a. har en kraftig förmåga att absorbera eller reflektera inIn this work, spatially resolved localized surface plasmons (LSPs) in individual silver nanocubes and nanoellipsoids are imaged with a photoemission electron microscope (PEEM). Using broadband laser pulses with photon energies below the work function threshold of the material, multiphoton photoemission (MPPE) processes coupled to the LSPs governs the strong enhancement of the plasmonic near-field

The diploma work is partly a collaboration with the Swedisch furniture company IKEA. The task has been to develop a childrens bed with the aim to fulfil the need for compact solutions in childrens rooms, encourage childrens development and incorporate play. The result has become two parallel concepts, where one has taken guidelines from IKEA´s way of working with product development, its restrict
