Tidskriftsartikel (refereegranskat)abstract
- Objectives: To investigate whether the association between pain intensity and willingness to undergo surgery is explained by walking difficulties, in patients with knee or hip osteoarthritis (OA). Methods: This is an observational study using data from the Better management of patients with Osteoarthritis (BOA) register, which collects data from a publicly financed self-management programme for people with OA in Sweden. We included all patients with knee or hip OA who attended the baseline visit between 2008 and 2016. We conducted separate mediation analyses within a counterfactual framework to estimate the mediation effect of walking difficulties (yes/no) on willingness to undergo surgery (yes/no) for each one-point increase in pain (0–10 on a numeric rating scale), adjusted for relevant confounders. Results: We included 72,131 patients (69% women, mean age 66, mean pain 5.4, 81% had walking difficulties, 27% was willing to undergo surgery). A one-point increase in pain intensity was associated with 1.53 (95% CI: 1.51; 1.55) higher odds of being willing to undergo surgery. Walking difficulties mediated 10%–25% of the effect of one-point increase in pain when pain was <8/10, while at pain ≥8/10 this percentage decreased to 3%. Conclusions: More than 80% of the BOA patients have mild to moderate pain (<8/10) and walking difficulties can mediate up to a quarter of the total effect of pain on the willingness to undergo surgery in these patients. Trials to evaluate the potential to lower surgery demand by reducing walking difficulties in people with these characteristics are needed.

A HISTORY OF BUSINESS CARTELS - INTERNATIONAL POLITICS, NATIONAL POLICIES AND ANTI-COMPETITIVE BEHAVIOUR
- 2022
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- International cartels are powerful organizations that impact our everyday lives, although they are little known. This book presents 15 historical case studies of international cartels that include agricultural and mineral commodities, the machinery industry, telephone equipment, whiskey and cement. These cases reveal that international cartels manipulated prices and shared markets over many decades but that their real impact was far wider. The global convergence towards criminalizing serious cartel conduct has seen a revival in historical research on cartels and competition policy. The regulation of anti-competitive behaviour has changed over time. To understand why the US, European and other modern economies altered their policies through the 20th century, it is critical to understand when, how and why governments have interacted with, and been influenced by, business organizations such as cartels. This volume draws together researchers from different nations to examine the impact of international cartels on the experience of individual nations, those nations’ interactions with one or more international cartels, and ultimately the interactions of individual nations with the wider international community. This book will be of interest to researchers, academics and advanced students in the fields of business and economic history, political economy, and government policy, as well as those interested in cartels and their impact on the wider economy.

A History of National Museums in Europe 1750-2010: Mobilization and Legitimacy, Continuity and Change.
- 2015
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- National Museums and Nation-building in Europe 1750–2010 is placed at the heart of the intersection where the socio-political and the scientific logics meet in the context of nation-building, representing and legitimizing nations in and through national museums. National museums and their representations have therefore within a world of nations become an international standard of nation-claiming and nation-branding. We approach the study of national museums as a historic and contemporary process of institutionalized negotiations of dominant values that constitute a basis for national communities and dynamic state formations. The national museum is thus a knowledge-based socio-political institution, with corresponding collections and displays that ultimately claim, articulate and represent dominant national values and myths. National Museums and Nation-building in Europe 1750–2010 will respond to basic questions about the establishment and dynamics of national museums by investigating the trajectory, context and timing of their establishment. It will also answer more complex questions. To what extent and with what consequences do the trajectory and timing of nation- and state-making processes interact with museum initiatives, creations, societal challenges and justifications?

A history of Swedish broadcasting : communicative ethos, genres and institutional change / edited by Monika Djerf-Pierre & Mats Ekström
- 2013
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Broadcast communication has had a profound effect on modern society in the 20th and early 21st centuries. A growing international field of research has examined the historical development of broadcasting within various social and historical contexts, but also has made significant contributions to the understanding of media communication in general. Central topics in this discussion concern the relationships between technological innovations, institutional arrangements, social relations and culture. This book analyses the historical developments of Swedish broadcasting from the introduction of radio in the mid-1920s until the early 2000s. In relation to international research, it explores key aspects of how broadcast media emerged as a way to communicate over distance, connected to audiences, and evolved into central institutions and socio-cultural universes in society. The chapters are arranged in five thematic sections focusing on the invention and early development of radio and television, audience orientation, professional practices, broadcast genres, and institutional changes. The book derives from a large-scale research programme on Swedish broadcast history comprising about 50 studies and led by the “Swedish Foundation of Broadcast Media History”.

Insects associated with fruit bodies of the wood-decaying fungus Oak mazegill (Daedalea quercina) in mixed oak forests in southern Sweden

Tidskriftsartikel (refereegranskat)abstract
- Polypores host species rich insect assemblages, but relatively few polypore species have been studied in detail. We investigated insect assemblages associated with the fruit bodies of Daedalea quercina, a specialist species on oak in southern Sweden. Fruit bodies (n = 228) were collected from 25 nature reserves and woodland key habitats, and were taken into the laboratory to collect emerging insects. A total of 245 insect individuals were recorded, belonging to at least 45 species. The numerically dominant fungivores were the tineid moths Montescardia tessulatella (n = 38 individuals) and Nemapogon fungivorellus (n = 10) and the coleopteran Ennearthron cornutum (Ciidae) (n = 44). Altogether 40 individuals of hymenopteran parasitoids were recorded, belonging to Braconidae (Exothecinae, Microgastrinae and Rogadinae, altogether 6 spp.), Ichneumonidae (Banchinae, Cryptinae and Orthocentrinae, altogether 4 spp.), Torymidae (1 sp.), Perilampidae (1 sp.) and Scelionidae (1 sp.). Most of the remaining insect species are not specifically associated with fruit bodies, but occupy many types of decaying material. In conclusion, D. quercina hosted a low number of insect individuals in general and only a few coleopteran species. The fungus apparently has only one specialist species, N. fungivorellus, which is a near-threatened (NT) species on the Swedish red list; the record from Norra Vi is the first from the Jönköping. The overall low number of insect individuals and the dominance of Lepidoptera among the fungivores is possibly explained by the tough fruit bodies of D. quercina, which only moths are able to utilize; fruit bodies which had already started to rot were devoid of moths.

Calculational aspects of electron-phonon coupling at surfaces
- 2008

Ingår i: J. Phys: Condens. Matter. - : IOP Publishing. - 1361-648X .- 0953-8984. ; 20

Tidskriftsartikel (refereegranskat)abstract
- We study the validity of two frequently used approximations in calculations of electron–phonon coupling at surfaces. The rigid-ion approximation is a standard approximation used for the bulk metals. On the basis of density functional theory calculations, we find that for Be this approximation is as valid for surface atoms as for bulk atoms. In addition, the slab method for calculations of a phonon induced surface state lifetime is examined. The convergence of the electron–phonon matrix element with respect to the thickness of the slab is studied for several systems. When the number of slab layers is increased, the net effect of decreasing overlap and increasing number of final states depends strongly on the decay length of the surface state wavefunction and the band structure.

Model Eliashberg function for surface states
- 2008
-
Ingår i: Applied Surface Science. ; 254:23
-
Tidskriftsartikel (refereegranskat)abstract
- We present a simplified procedure for the analysis of the phonon-induced lifetimes of surface states. The model includes information about the electron and phonon structure and is thus more reliable than procedures based on phonon Debye models. We apply the model to calculate the lifetime broadening of Cu(1 1 1) and Al(0 0 1) surface states. The obtained Eliashberg functions and lifetimes are in reasonable agreement with previous detailed studies.

Using X-chromosomal markers in relationship testing: Calculation of likelihood ratios taking both linkage and linkage disequilibrium into account
- 2011
-
Ingår i: Forensic Science International: Genetics. - : Elsevier BV. - 1872-4973 .- 1878-0326. ; 5:5, s. 506-511

Tidskriftsartikel (refereegranskat)abstract
- X-chromosomal markers in forensic genetics have become more widely used during recent years, particularly for relationship testing. Linkage and linkage disequilibrium (LD) must typically be accounted for when using close X-chromosomal markers. Thus, when producing the weight-of-evidence, given by a DNA-analysis with markers that are linked, the normally used product rule is invalid. Here we present an implementation of an efficient model for calculating likelihood ratios (LRs) with markers on the X-chromosome which are linked and in LD. Furthermore, the model was applied on several cases based on data from the eight X-chromosomal loci included in the Mentype® Argus X-8 (Biotype). Using a simulation approach we showed that the use of X-chromosome data can offer valuable information for choosing between the alternatives in each of the cases we studied, and that the LR can be high in several cases. We demonstrated that when linkage and LD were disregarded, as opposed to taken into account, the difference in calculated LRs could be considerable. When these differences were large, the estimated haplotype frequencies often had a strong impact and we present a method to estimate haplotype frequencies. Our conclusion is that linkage and LD should be accounted for when using the tested set of markers, and the used model is an efficient way of doing so.
