The Phoenix syndrome : Netroots organizations strategies to gain and maintain digital resource abundance
The development of social media challenges the established conceptualizations of resources in social movements. While previous theories largely illustrated social movements as constantly searching for new and more resources, the development of social media has allowed some actors to gather and mobilize extensive resources rapidly, calling for an analysis of resource abundance. The aim of this artiThe development of social media challenges the established conceptualizations of resources in social movements.

On buckling and fracture of thin elastic-plastic foils : Part of special issue: 1st Virtual European Conference on Fracture - VECF1
The interaction of simultaneous fracture and buckling constitutes problems at manufacturing and handling of thin foils. Buckling occurs as an additional event that complicates the prediction of the critical load that may lead to fracture. For most sufficiently thin foils the plastic slip occurs through the foil thickness which leads to reduction of the cross section width until the foil fails. The
The colloidal structure of a cellulose fiber
Abstract: We present a small angle X-ray scattering (SAXS) study of the colloidal structure of regenerated cellulose fibers, air-gap spun from an ionic liquid solution. Based on the data, and a different interpretation of the anisotropic SAXS pattern, we propose a slightly different colloidal structure of the fibers, than what is commonly assumed for regenerated cellulose fibers. Fibers with two d
The role of environmental requirements in Swedish public procurement of bus transports
The transport sector needs to become sustainable and public transport has an important role to play. Green public procurement has proven to have great potential to influence the transition to a sustainable public transport sector. Sweden is a good example of a country that uses public procurement in the public transport sector to a large extent and has at the same time come far in the transition t

Improved quality of InSb-on-insulator microstructures by flash annealing into melt
Monolithic integration of III-V semiconductors with Silicon technology has instigated a wide range of new possibilities in the semiconductor industry, such as combination of digital circuits with optical sensing and high-frequency communication. A promising CMOS compatible integration process is rapid melt growth (RMG) that can yield high quality single crystalline material at low cost. This paper

Medical crisis checklists in the emergency department : a simulation-based multi-institutional randomised controlled trial
Background: Studies carried out in simulated environments suggest that checklists improve the management of surgical and intensive care crises. Whether checklists improve the management of medical crises simulated in actual emergency departments (EDs) is unknown. Methods: Eight crises (anaphylactic shock, life-threatening asthma exacerbation, haemorrhagic shock from upper gastrointestinal bleeding
Shock deformation in zircon grains from the Mien impact structure, Sweden
Recognition of impact-induced deformation of minerals is crucial for the identification and confirmation of impact structures as well as for the understanding of shock wave behavior and crater formation. Shock deformed mineral grains from impact structures can also serve as important geochronometers, precisely dating the impact event. We investigated zircon grains from the Mien impact structure in
Gender Bias in Opinion Aggregation
Gender biases have been documented in many areas including hiring, promotion, or performance evaluations. Many of these decisions are made by committees. We experimentally investigate whether committee deliberation contributes to gender biases. In our experiments, participants perform a real effort task and then rate the task performance of other participants. Across treatments we vary the extent
PD-L1 amplification is associated with an immune cell rich phenotype in squamous cell cancer of the lung
Gene amplification is considered to be one responsible cause for upregulation of Programmed Death Ligand-1 (PD-L1) in non-small cell lung cancer (NSCLC) and to represent a specific molecular subgroup possibly associated with immunotherapy response. Our aim was to analyze the frequency of PD-L1 amplification, its relation to PD-L1 mRNA and protein expression, and to characterize the immune microenv
Interventions to minimize blood loss in very preterm infants - A systematic review and meta-analysis
Blood loss in the first days of life has been associated with increased morbidity and mortality in very preterm infants. In this systematic review we included randomized controlled trials comparing the effects of interventions to preserve blood volume in the infant from birth, reduce the need for sampling, or limit the blood sampled. Mortality and major neurodevelopmental disabilities were the pri
Two screening instruments for collecting alcohol-related information from expectant mothers and fathers : Testing the reliability of the Parent Alcohol Screening Questionnaire and the Social Support for an Alcohol-Free Pregnancy Questionnaire
The aim is to test the reliability of two alcohol screening instruments: (1) The Parent Alcohol Screening Questionnaire (PASQ5), and (2) the Social Support for an Alcohol-free Pregnancy (SSAFP) questionnaire. This is a cohort study from the south of Sweden using repeated surveys during pregnancy. To examine if responses differed according to different data collection methods, two cohorts consistin
Endovascular Relining of Chronically Occluded Infrainguinal Venous Bypass Grafts
Background: Treatment of chronically occluded infrainguinal venous bypass grafts in patients presenting with recurrent chronic limb threatening limb ischemia (CLTI) represent a clinical challenge. Recent case reports have suggested the use of endovascular recanalization techniques without preceding thrombolysis. This study assesses feasibility and mid-term outcomes of this technique. Results: A re

Analysis of Thermal Stress in a Solid Oxide Fuel Cell Due to the Sulfur Poisoning Interface of the Electrolyte and Cathode
The interface of an electrolyte and cathode strongly determines the oxygen reduction reaction and cell stability, but it is susceptible to sulfur impurities like SO2 in air. In this study, a 3D solid oxide fuel cell model is developed based on experimental characterization to reveal sulfur-deactivating active cathodes. The results indicate that both the average values for electric and ionic curren
Implementation of National Guidelines increased survival in advanced ovarian cancer - A population-based nationwide SweGCG study
Aim: The first Swedish National Guidelines for Ovarian Cancer (NGOC) were published in 2012. We aimed to evaluate surgical outcomes and survival in patients with stage IIIC-IV disease, before and after the NGOC implementation. Method: Women with primary epithelial ovarian cancer, FIGO stage IIIC–IV, registered in the Swedish Quality Registry for Gynecologic Cancer 2008–2011 and 2013–2016 were incl
Parallel consistency in constraint programming
Program parallelization becomes increasingly important when new multi-core architectures provide ways to improve performance. One of the greatest challenges of this development lies in programming parallel applications. Using declarative languages, such as constraint programming, can make the transition to parallelism easier by hiding the parallelization details in a framework. Automatic parallel
The uropygial gland microbiome of house sparrows with malaria infection
Birds secrete preen oil from the uropygial (preen) gland which is used to maintain feather integrity and communicate through odour. The uropygial secretion is believed to influence host attractiveness to biting insects, thereby altering the risk of infection by vector-transmitted blood parasites. Previous studies have documented a presence of bacteria in the uropygial secretion; however, the micro
