In his recent work, Eco abandons his conventionalist theory of pictures, which was heavily censored by, among others, the present author. In so doing, however, Eco now goes to the other extreme, claiming that television images are like mirrors, which are no signs. It is my contention that Eco fails to come up with a more acceptable theory of iconicity. Since Eco is one of the few semioticians conc

The chapter gives an overall picture of the conditions of labour market entry for young people (16-19 years) and young adults (20-24 years) and their social exclusion in Sweden from the early 1990s until now. The chapter consists of three sections. The first section provides background information on the entry of young people on the Swedish labour market. The overview summarizes research findings

In this article the medialization of everyday life is discussed, as it appears in the norwegian novelist Jan Kjaerstads "Förföraren" (The Seducer). I mainly focus upon the intermedia aspects between literature and other art and media forms, such as TV, film, music, etc. Another aspect discussed in the article is the cluster of connections between Norway/Scandinavia and the rest of the world, which

The aim of this study was to investigate use and need for assistive devices (AD) in a cross-national European sample. Data from the ENABLE-AGE research project were utilised involving very old persons in Sweden, Germany, Latvia, Hungary and the United Kingdom. Of the total sample 65% reported that they had and used one or more AD, and 14% reported unfilled need for AD. The most commonly used AD we

This dissertation explores how the school subject Swedish is constructed for various groups of upper secondary school students and how the meeting between teacher and pupils is embodied in a range of Swedish subjects. The overall aim of the study is to illustrate why the teaching of Swedish in the classes under investigation takes place the way it does, as well as to discuss possible changes on a

Popular Abstract in Swedish ”Att leva med cancer som äldre, livskvalitet och upplevelse av mening” Cancer drabbar företrädesvis äldre personer och är en sjukdom som blir vanligare i takt med det stigande antalet äldre i befolkningen. Cancer hos äldre innebär en komplex situation eftersom åldrandet är präglat av stora individuella förändringar med ökande sjuklighet, nedsatt funktionell förmåga, föThe overall aim of this thesis was to investigate quality of life in people aged 75 and older with cancer in relation to age, gender, presence and type of complaints, comorbidity, living conditions, perceived economic situation, sense of coherence, receiving help for daily living and social resources. The aim was also to investigate older people’s experiences and the meaning of living with cancer

Previous studies have shown that the functional efficacy of intrastriatal transplants of fetal dopamine (DA) neurons in the rat Parkinson model depends on their ability to establish a new functional innervation of the denervated striatum. Here we report that the survival, growth, and function of the grafted DA neurons greatly depend on the severity of the lesion of the host nigrostriatal system. F

In this study, the transmission and reflection of two conductive fabrics are investigated in the frequency range from 2 to 18 GHz. One of the fabrics is a non-woven polypyrrole and the other consists of a polyethylene warp with steel threads in the weft. Reflection and transmission measurements are performed in order to characterize the electromagnetic properties of the materials. Reflection measu

BACKGROUND: Cost-effective fermentation of lignocellulosic hydrolysate to ethanol by Saccharomyces cerevisiae requires efficient mixed sugar utilization. Notably, the rate and yield of xylose and arabinose co-fermentation to ethanol must be enhanced. RESULTS: Evolutionary engineering was used to improve the simultaneous conversion of xylose and arabinose to ethanol in a recombinant industrial Sacc

The asymptotic distribution of the maximum Mn=max1= 0 as t -> ~ or if Σr2t<~, then the limiting distribution is the same as for a sequence of independent normal variables. Here it is shown that this also follows from a weaker condition, which only puts a restriction

A combined sample preparation and sample presentation device, Integrated Selective Enrichment Target (ISET), consisting of an array with 96 perforated nanovials is described. Each perforated nanovial can be filled with soild-phase extraction media for purification and concentration of biomolecules prior to mass spectrometry. The ISET platform provides an efficient, economic and generic sample trea

The rapid progress in scanning probe microscopy (SPM) techniques in the last decade has induced an increasing need for manufacturing advanced SPM tips. One important case is conductive and transparent tips. For such tips, only a few techniques have been proposed. which are either expensive or have poor reproducibility. We here propose a simple and cheap sol-gel technique to prepare fibers with a s

Between 1991 and 1994 the number of beds in the surgical clinic at a central hospital in Southern Sweden was cut back by almost 50%. To develop the nursing care and to control the effects of the budgetary cuts, an intervention, including nursing care development, of an organization that would secure continuity in the nurse-patient relationship, individually planned care and quality assurance for a

Popular Abstract in Swedish Modellering och simulering är etablerade tekniker för att lösa designproblem inom många olika ingenjörsdiscipliner idag. Dedicerade språk, såsom Modelica, och effektiva mjukvaror finns också tillgängliga. I denna avhandling presenteras en språklig utvidgning av Modelica, Optimica, som är avsedd för formulering av dynamiska optimeringsproblem. För att demonstrera användnModeling and simulation are established techniques for solving design problems in a wide range of engineering disciplines today. Dedicated computer languages, such as Modelica, and efficient software tools are available. In this thesis, an extension of Modelica, Optimica, targeted at dynamic optimization of Modelica models is proposed. In order to demonstrate the Optimica extension, supporting sof

Germ layer formation and primary axis development rely on Fibroblast growth factors (FGFs). In Xenopus, the secreted serine protease HtrA1 induces mesoderm and posterior trunk/tail structures by facilitating the spread of FGF signals. Here, we show that the serpin Protease nexin-1 (PN1) is transcriptionally activated by FGF signals, suppresses mesoderm and promotes head development in mRNA-injecte
