Causal Powers and Social Ontology

Over the last few decades, philosophers and social scientists have applied the so-called powers ontology to the social domain. I argue that this application is highly problematic: many of the alleged powers in the social realm violate the intrinsicality condition, and those that can be coherently taken to be intrinsic to their bearers are arguably causally redundant. I end the paper by offering a

H.264 Video Frame Size Estimation

This report describes a method to estimate the video bandwidth for IP cameras using the H.264 standard. The precise determination of bandwidth allows us to model the network access as a scheduling problem and/or estimate the amount of data that would traverse it during different periods. The paper is written to be as didactic as possible and presents a set of experiments, conducted in an industria

Initial assessment of a multi-model approach to spring flood forecasting in Sweden

Hydropower is a major energy source in Sweden and proper reservoir management prior to the spring flood onset is crucial for optimal production. This requires useful forecasts of the accumulated discharge in the spring flood period (i.e. the spring-flood volume, SFV). Today's SFV forecasts are generated using a model-based climatological ensemble approach, where time series of precipitation and te

Beyond Asylum - Labor Market Integration Challenges in Sweden

This article takes stock of recent changes to Sweden’s immigration policy and draws upon statistical data to show the effect of the new immigration regime. It discusses the structural economic challenge of integrating immigrants who lack education and job training, and offers Sweden as a reference (or perhaps cautionary tale) for other coun- tries seeking to change their immigration policies. This

Targeting Transfusion-Related Acute Lung Injury: The Journey From Basic Science to Novel Therapies

Objectives: Transfusion-related acute lung injury is characterized by the onset of respiratory distress and acute lung injury following blood transfusion, but its pathogenesis remains poorly understood. Generally, a two-hit model is presumed to underlie transfusion-related acute lung injury with the first hit being risk factors present in the transfused patient (such as inflammation), whereas the

Bostadsbränder i storstadsområden

Syftet med detta forskningsprojekt är att i samverkan med räddningstjänster, kommuner och andra berörda aktörer i storstadsområden, analysera bakomliggande bestämningsfaktorer till rumsliga, bebyggelse - och befolkningsmässiga skillnader i förekomsten av bostadsbränder. Projektet ska genom samproduktion med berörda aktörer utveckla förslag på hur brandsäkerhetsarbetet kan bedrivas och utvärderas i

Adaptive Landscapes

'Adaptive Landscape' was first formulated as a heuristic model or metaphor for the evolutionary process by late population geneticist Sewall Wright in a famous paper published in 1932. The metaphor of an adaptive landscape with adaptive peaks of high fitness, separated by adaptive valleys of low fitness attracted a lot of interest from contemporary and later evolutionary biologists and inspired re

Synchronising geometric representations for map mashups using relative positioning and Linked Data

Map mashups, as a common way of presenting geospatial information on the Web, are generally created by spatially overlaying thematic information on top of various base maps. This simple overlay approach often raises geometric deficiencies due to geometric uncertainties in the data. This issue is particularly apparent in a multi-scale context because the thematic data seldom have synchronised level

Ämnade för restaurangarbete? : Om politisk styrning och lågutbildade ungdomars väg fram till arbetsmarknadens tröskel

Den första januari 2012 sänkte den då sittande alliansregeringen momssatsen för restaurang- och cateringtjänster från 25 % till 12 %. Det övergripande målet med den lägre momssatsen är att stimulera efterfrågan på okvalificerad arbetskraft genom att skapa förutsättningar för lägre priser och därmed ökad efterfrågan på restaurangföretagens tjänster.Under tiden efter genomförandet av den sänkta momsA significant part of the labour market debate is devoted to issues concerning problematic youth. Expressions like “the lost generation” is coined to address the very core of the matter. It captures the difficulties for low-skilled young people to gain a sustainable work life in an education-oriented society. A strategy to increase employment opportunities specifically suited for the latter group

When is PID a good choice?

A new and freely available model-based PID design tool for Matlab is introduced. It can be used to solve Maximal Integral Gain Optimization (MIGO) and (load) Integral Absolute Error (IAE) problems. Robustness is ensured through H-inf constraints on the closed-loop transfer functions. A Youla parameter (Q design) method for comparison with the optimal linear time-invariant (LTI) controller for the

Antibodies to a strain-specific citrullinated Epstein-Barr virus peptide diagnoses rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease. Anti-citrullinated protein antibodies (ACPA) are crucial for the serological diagnosis of RA, where Epstein-Barr virus (EBV) has been suggested to be an environmental agent in triggering the onset of the disease. This study aimed to analyse antibody reactivity to citrullinated EBV nuclear antigen-2 (EBNA-2) peptides from three dif

Superamphiphobic coatings based on liquid-core microcapsules with engineered capsule walls and functionality

Microcapsules with specific functional properties, related to the capsule wall and core, are highly desired in a number of applications. In this study, hybrid cellulose microcapsules (1.2 ± 0.4 μm in diameter) were prepared by nanoengineering the outer walls of precursor capsules. Depending on the preparation route, capsules with different surface roughness (raspberry or broccoli-like), and thereb

Auditory opportunity and visual constraint enabled the evolution of echolocation in bats

Substantial evidence now supports the hypothesis that the common ancestor of bats was nocturnal and capable of both powered flight and laryngeal echolocation. This scenario entails a parallel sensory and biomechanical transition from a nonvolant, vision-reliant mammal to one capable of sonar and flight. Here we consider anatomical constraints and opportunities that led to a sonar rather than visio
