The predictability of high impact weather events on multiple time scales is a crucial issue both in scientific and socio-economic terms. In this study, a statistical-dynamical downscaling (SDD) approach is applied to an ensemble of decadal hindcasts obtained with the Max-Planck-Institute Earth System Model (MPI-ESM) to estimate the decadal predictability of peak wind speeds (as a proxy for gusts) over Europe. Yearly initialized decadal ensemble simulations with ten members are investigated for the period 1979–2005. The SDD approach is trained with COSMO-CLM regional climate model simulations and ERA-Interim reanalysis data and applied to the MPI-ESM hindcasts. The simulations for the period 1990–1993, which was characterized by several windstorm clusters, are analyzed in detail. The anomalies of the 95 % peak wind quantile of the MPI-ESM hindcasts are in line with the positive anomalies in reanalysis data for this period. To evaluate both the skill of the decadal predictability system and the added value of the downscaling approach, quantile verification skill scores are calculated for both the MPI-ESM large-scale wind speeds and the SDD simulated regional peak winds. Skill scores are predominantly positive for the decadal predictability system, with the highest values for short lead times and for (peak) wind speeds equal or above the 75 % quantile. This provides evidence that the analyzed hindcasts and the downscaling technique are suitable for estimating wind and peak wind speeds over Central Europe on decadal time scales. The skill scores for SDD simulated peak winds are slightly lower than those for large-scale wind speeds. This behavior can be largely attributed to the fact that peak winds are a proxy for gusts, and thus have a higher variability than wind speeds. The introduced cost-efficient downscaling technique has the advantage of estimating not only wind speeds but also estimates peak winds (a proxy for gusts) and can be easily applied to large ensemble datasets like operational decadal prediction systems.

SBTX, a novel toxin from soybean, was purified by ammonium sulfate fractionation followed by chromatographic steps DEAE-Cellulose, CM-Sepharose and Superdex 200 HR fast-protein liquid chromatography (FPLC). Lethality of SBTX to mice (LD50 5.6 mg/kg) was used as parameter in the purification steps. SBTX is a 44-kDa basic glycoprotein composed of two polypeptide chains (27 and 17 kDa) linked by a disulfide bond. The N-terminal sequences of the 44 and 27 kDa chains were identical (ADPTFGFTPLGLSEKANLQIMKAYD), differing from that of 17 kDa (PNPKVFFDMTIGGQSAGRIVMEEYA). SBTX contains high levels of Glx, Ala, Asx, Gly and Lys and showed maximum absorption at 280 nm, epsilon(1 cm) (1%) of 6.3, and fluorescence emission in the 290-450nm range upon excitation at 280nm. The secondary structure content was 35% alpha-helix, 13% beta-strand and beta-sheet, 27% beta-turn, 25% unordered, and 1% aromatic residues. Immunological assays showed that SBTX was related to other toxic proteins, such as soyatoxin and canatoxin, and cross-reacted weekly with soybean trypsin inhibitor and agglutinin, but it was devoid of protease-inhibitory and hemagglutinating activities. The inhibitory effect of SBTX on growth of Cercospora sojina, fungus causing frogeye leaf spot in soybeans, was observed at 50 mu g/ml, concentration 112 times lesser than that found to be lethal to mice. This effect on phytopathogenic fungus is a potential attribute for the development of transgenic plants with enhanced resistance to pathogens. (c) 2007 Elsevier Ltd. All rights reserved.

Denna uppsats dokumenterar uppkomst, frontpersoner och verksamhet för Dalarnes sjuksköterskeförening (DSF) mellan åren 1920-1933, vilket är en lokal sjuksköterskeförening som senare blev underavdelning till riksföreningen Svensk sjuksköterskeförening (SSF). DSF var den första lokala sjuksköterskeföreningen och startades 1920 av sjuksköterskor kring området Falun/Borlänge. Det var inte en elitförening likt SSF som i sin professionalisering enbart ville avskärma sig från de underordnade som biträden och kämpa för status och kalltanken. DSF var en förening som ville stärka kårandan men även arbeta för löne- och arbetsförhållandefrågor, vilket på den tiden egentligen hörde samman med socialistiska föreningar. I sin verksamhet ville de även få till stånd en platsbyrå för föreningens medlemmar. Det var en politiskt oberoende förening som arbetade fackligt. År 1933 blev Dalarnes sjuksköterskeförening en underavdelning till SSF som från och med det året började arbeta fackligt på lokalföreningars begäran.

Uppsatsens syfte har varit att undersöka hur Kungliga Gotlands infanteriregemente drabbades av spanska sjukan under 1918-1920. Det har även jämförts hur detta regemente drabba¬des i jämförelse med Dalarnas och Västmanlands regementen under 1918. Frågeställning¬arna som besvarats handlar om hur många som insjuknade och dog, hur regementets ansva¬riga agerade samt vilka åtgärder som vidtogs när epidemin hade nått regementet. Det huvudsakliga materialet jag har använt mig av är förste provinsialläkarens årsberättelser och regementets inkomna och utgående skrivelser. Studiens resultat visar att Kungliga Gotlands infanteriregemente med sina cirka 500 sjuk¬domsfall och fyra dödsfall under epidemins första period, 1918 drabbades i hög grad i jämfö¬relse med Dalregementet, men i liten grad i jämförelse med Västmanlands rege¬mente. Anledningen till att regementet på Gotland klarade sig relativt lindrigt från spanska sjukan kan bero på att en fungerande sjukvård snabbt kunde sättas in samt att man vidtog andra åt¬gärder såsom inskränkningar på permissioner, striktare personlig hygien och renlighet i loka¬lerna samt skyddsympning.

The purpose of this article was to illuminate existing educational ideologies in the Swedish fiddler movement (Spelmansrörelsen) 1923-1927. This period was characterized by the organization and to some extent institutionalization of Swedish folk music. Furthermore, the purpose was to discuss the results in relation to the folk music education of today. The empirical data was taken from the journal Hembygden, which was a magazine for scholars, enthusiasts and practitioners of folk music. Theoretically, the study was based on a concept of ideology developed by Sven-Eric Liedman: in every time there are two basic forms of identifiable ideology, manifest and latent. From the empirical material as a whole (around 900 articles), a selection was made to find articles dealing with aspects of learning among the fiddlers (33 articles). After content analysis the following themes were generated: Fiddlers’ repertoire, Fiddlers’ masters, Rooms for learning, Learning formation. The writers in Hembygden often emphasized the autodidactic aspects of learning and especially the importance of learning by ear. This manifest ideology of authenticity presumed that learning directly from another fiddler by playing together was to prefer to formal schooling. In spite of a tendency towards more ensemble playing, the folk music education of today in Sweden is characterized by a similar retrospective ideology as in the 1920s.

Denna uppsats undersöker olika musikaliskt hörbara kännetecken som är specifika i Max Martins produktioner. Musikaliska kännetecken refererar till hörbara kännetecken i den här uppsatsen och kommer att beröra formen på verket, tonart, rytm, frasindelningar, sångens dynamik, melodin och känslan som artisten framför i sången. Först analyseras tre produktioner producerade och skrivna av Max Martin och sedan jämförs de med tre stycken produktioner som är producerade och skrivna av andra producenter och låtskrivare. Analysen sker genom en så kallad ljudhändelsebeskrivning för att få fram material som går att jämföras och det sker med hjälp av den komparativa metoden. I resultatet går det tydligt att se musikaliskt hörbara kännetecken som är specifika i Max Martins produktioner. Det går även att se vilka musikaliskt hörbara kännetecken som är gemensamma för alla inspelningar som har analyserats i uppsatsen.

This investigation considers the development of class music teaching in New South Wales and Victoria during the first seventy-two years of state-supported primary education. The first chapter describes the English background including music teaching methods (resulting from the mid-nineteenth century English choral singing movement) and the subsequent development of music teaching in English elementary schools. The promotion of school music is then considered on a broadly chronological basis in the two states and several themes are identified in relation to school music policy and practice. These include the status of music (core curriculum or extra-curricular subject), who should teach music (generalist or specialist teachers), what teaching methods and music notation should be used (staff or Tonic Sol-fa), musical training for generalist teachers, and curriculum content in relation to the aims and objectives of school music. Comparisons are made between developments in both states and between both states and English school music. The final chapter demonstrates the relevance of many of the historical themes identified for music education today. The thesis concludes by identifying a recurring problem from the past. namely the lack of co-ordination between various aspects of school music policy, as the most serious problem to be overcome in the future.

As a result of negative net immigration during the 1890s depression, Australians at the time of Federation were preoccupied about the slow rate of growth of the population. The non-Aboriginal population at the end of 1904 was approximately three and three-quarter million. and the publication in March 1904 of the Report of the New South Wales Royal Commission on the Decline of the Birth Rate and the Mortality of Infants did nothing to allay these concerns. Despite the perceived need for more people. the desire for racial unity was paramount. The main goals of policy makers at the time were to preserve a 'white' and essentially British Australia and create an imperial bastion in the Southern Hemisphere.

Prior to the First World War, the selling of the Australian wool clip rested firmly in the hands of the large woolbroking firms. An agreement between the British and Australian governments during the war saw many of the wool-selling functions of broking firms taken over by the Central Wool Committee. At the conclusion of hostilities, brokers moved to regain their role in the market. However, market conditions had changed. On an international level, traditional trading relationships had broken down, leaving commodity markets unstable and prices unpredictable. On a local level, woolgrowers had benefited from the wartime orderly marketing scheme and the high price guaranteed by the British government for their wool clip. As a result, they had begun to demand a greater role in the selling arrangements of their clip. This paper investigates the debates over the sale of the wool clip in the 1920s and how woolbrokers and growers eventually arrived at an understanding as to the manner in which the market should operate.

This article examines the notion of the 'scientist as a moral person' in the light of the early stages of the commodification of science and the transformation of research into a big enterprise, operating on the principle of the division of labour. These processes were set in train at the end of the 19th century. The article focuses on the concomitant changes in the public persona and the habitus of scientific entrepreneurs. I begin by showing the significance of the professional networks that were built up and maintained to further a group's research ideas and the careers of its members, thus demonstrating one condition on which depended their practice of science and their ability to earn a living. This leads to a characterization of the changing styles of work, thought and life, and to a consideration of public perceptions and of the ways in which a new self-image of scholarship and science was fashioned. A critical discussion of the public role of these mandarin scientists follows in order to highlight the strains created by the commodification of science at a time of international tensions and conflicts, when shared beliefs in scholarly cosmopolitanism were subverted by appeals to science and scholarship to work in the service of one's own nation as its 'courtiers'. Various considerations of peculiar analogies between national styles of research and the style of social organization are then noted. In the final section, the article queries the long-term impact of these developments on the ideal of the scientist as a 'moral person'. Taking a cue from Max Weber and pursuing reflections by Zygmunt Bauman on 'science moralized', I argue that the emergence of a type of 'specialists without spirit' was an unintended but fatal consequence of the changes in research practices promoted by scientific entrepreneurs such as Du Bois-Reymond. I conclude that the temptation to sever the ties to a general ethos of civil virtues lay in the rationalization, specialization and potential de-humanization of the objectifying scientific outlook once advocated for its efficiency.

The market for insurance has become increasingly competitive in recent years. However, it has not always been so. At the end of the nineteenth century, it was characterized by a highly concentrated and tightly controlled oligopolistic market structure. As such, the history of the fire insurance industry provides an interesting case study in the development of collusive behaviour amongst firms. Up to 1897, pricing agreements among firms were generally short-lived, and were followed by periods of intense competition. After this point, an agreement was forged, which proved very resilient to market pressures and formed the basis of premium rate setting until the 1970s. This paper investigates the difference between this agreement and previous efforts to set premium rates, and points to some of the common features of the later compact, which explain its longevity.
