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”.

- 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.

- 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.

U.S. versus Sweden: The Effect of Alternative In-Work Tax Credit Policies on Labour Supply of Single Mothers
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- An essential difference between the design of the Swedish and the US in-work tax credit systems relates to their functional forms. Where the US earned income tax credit (EITC) is phased out and favours low and medium earnings, the Swedish system is not phased out and offers 17 and 7 per cent tax credit for low and medium low incomes and a lump-sum tax deduction equal to approximately 2300 USD for medium and higher incomes. The purpose of this paper is to evaluate the efficiency and distributional effects of these two alternative tax credit designs. We pay particular attention to labour market exclusion; i.e. individuals within as well as outside the labour force are included in the analysis. To highlight the importance of the joint effects from the tax and the benefit systems it appears particular relevant to analyse the labour supply behaviour of single mothers. To this end, we estimate a structural random utility model of labour supply and welfare participation. The model accounts for heterogeneity in consumption-leisure preferences as well as for heterogeneity and constraints in job opportunities. The results of the evaluation show that the Swedish system without phase-out generates substantial larger labour supply responses than the US version of the tax credit. Due to increased labour supply and decline in welfare participation we find that the Swedish reform is self-financing for single mothers, whereas a 10 per cent deficit follows from the adapted EITC version used in this study. However, where income inequality rises modestly under the Swedish tax credit system, the US version with phase-out leads to a significant reduction in the income inequality.

- Abstract PURPOSE: To assess the cardiovascular health and risk profile in middle-aged males making an entry to participate for their first time in a long-distance race. METHODS: Male first-time participants ≥45 years in the world's largest cross-country running race, the Lidingöloppet, were evaluated with a medical history and physical exam, European risk-SCORE, 12-lead ECG, echocardiography and blood tests. Further diagnostic work-up was performed when clinically indicated. RESULTS: Of 265 eligible runners, 153 (58%, age 51±5 y) completed the study. While the 10-year fatal cardiovascular event risk was low (SCORE: 1% (IQR: 0 - 1%)), mild abnormalities were common, e.g. elevated blood-pressure (19%), left ventricular hypertrophy (6%), elevated LDL cholesterol (5%). ECG changes compatible with "athlete's heart" were present in 82%, e.g. sinus bradycardia (61%) and/or early repolarization (32%). ECG changes considered training-unrelated were found in 24%, e.g. prolonged QTc: 13%; left axis deviation: 5.3%; left atrial enlargement: 4%). In 14 runners (9%) additional diagnostic work-up was clinically motivated, and 4 (2%) were ultimately discouraged from vigorous exercise due to QTc intervals >500 ms (n=2), symptomatic atrioventricular block (n=1), and a cardiac tumor (n=1). The physician exam and the ECG identified 12 of the 14 subjects requiring further evaluation. CONCLUSIONS: Cardiovascular evaluation of middle-aged men, including a physician exam and a 12-lead ECG, appears useful to identify individuals requiring further testing prior to vigorous exercise. The additional yield of routine echocardiography was small.

Tidskriftsartikel (refereegranskat)abstract
- The first EMEP intensive measurement periods were held in June 2006 and January 2007. The measurements aimed to characterize the aerosol chemical compositions, including the gas/aerosol partitioning of inorganic compounds. The measurement program during these periods included daily or hourly measurements of the secondary inorganic components, with additional measurements of elemental- and organic carbon (EC and OC) and mineral dust in PM1, PM2.5 and PM10. These measurements have provided extended knowledge regarding the composition of particulate matter and the temporal and spatial variability of PM, as well as an extended database for the assessment of chemical transport models. This paper summarise the first experiences of making use of measurements from the first EMEP intensive measurement periods along with EMEP model results from the updated model version to characterise aerosol composition. We investigated how the PM chemical composition varies between the summer and the winter month and geographically. The observation and model data are in general agreement regarding the main features of PM10 and PM2.5 composition and the relative contribution of different components, though the EMEP model tends to give slightly lower estimates of PM10 and PM2.5 compared to measurements. The intensive measurement data has identified areas where improvements are needed. Hourly concurrent measurements of gaseous and particulate components for the first time facilitated testing of modelled diurnal variability of the gas/aerosol partitioning of nitrogen species. In general, the modelled diurnal cycles of nitrate and ammonium aerosols are in fair agreement with the measurements, but the diurnal variability of ammonia is not well captured. The largest differences between model and observations of aerosol mass are seen in Italy during winter, which to a large extent may be explained by an underestimation of residential wood burning sources. It should be noted that both primary and secondary OC has been included in the calculations for the first time, showing promising results. Mineral dust is important, especially in southern Europe, and the model seems to capture the dust episodes well. The lack of measurements of mineral dust hampers the possibility for model evaluation for this highly uncertain PM component. There are also lessons learnt regarding improved measurements for future intensive periods. There is a need for increased comparability between the measurements at different sites. For the nitrogen compounds it is clear that more measurements using artefact free methods based on continuous measurement methods and/or denuders are needed. For EC/OC, a reference methodology (both in field and laboratory) was lacking during these periods giving problems with comparability, though measurement protocols have recently been established and these should be followed by the Parties to the EMEP Protocol. For measurements with no defined protocols, it might be a good solution to use centralised laboratories to ensure comparability across the network. To cope with the introduction of these new measurements, new reporting guidelines have been developed to ensure that all proper information about the methodologies and data quality is given.
