Interaction is an important aspect for children’s language development. The intervention model Prevention Education Program for Parents (PEPP) is currently under development within the research project Ord gör skillnad, Karolinska Institutet. PEPP is an intervention for parents to children aged 0–12 months who’s recently been diagnosed with hearing impairment. In PEPP parents receive guidance based on the child’s language environment which is mapped through Language ENvironment Analysis (LENA) and video analysis. LENA is a speech processing technological tool that analyzes the child’s language environment. The video analysis is made manually based on short video records of interactions between child and parent. The purpose of this study was to evaluate these mapping methods reliabilities to measure verbal conversational turns. The study also aimed to investigate if there’s a pattern between the amount of verbal conversational turns in a structured playtime and in the home environment. Four families with children aged 0:26–7:3 months participated. The child and parent interacted in a structured playtime that was analyzed with LENA and video analysis. Each family also made a LENA recording for an entire day in their home environment. The amount of verbal conversational turns in the structured playtime was analyzed by two assessors through video analysis. Inter-rater reliability was calculated, and a qualitative assessment was made for intervals in which the inter-rater reliability was <80%. The conformity between video analysis and LENA in the structured playtime was calculated. Further, a comparison was made between the amount of verbal conversational turns measured with LENA in home environment and structured environment. The inter-rater reliability in this study was high and in the qualitative assessment aggravating factors were identified. The conformity between video analysis and LENA analysis of the structured playtime was moderate. The amount of verbal conversational turns was higher for all participants in the structured environment compared to the home environment. This study indicates that video analysis is a reliable method. However, the aggravating aspects should be remedied in order to increase the reliability. The results confirm previous findings that demonstrate limitations with LENA’s ability to measure conversational turns in young infants. This study indicates that the number of conversational turns is higher in structured environments. To ensure the results in this study further research should be conducted. / Barn lär sig språket i interaktion med sin omgivning. Föräldrainterventionen Prevention Education Program for Parents (PEPP) utvecklas inom forskningsprojektet Ord gör skillnad, Karolinska Institutet. I PEPP handleds föräldrar till barn i åldrarna 0–12 månader med nyligen upptäckt hörselnedsättning kring samspel och kommunikation. Handledningen baseras på barnets språkmiljö som mäts med kartläggningsmetoderna Language ENvironment Analysis (LENA) och videoanalys. LENA är ett talprocessande teknologiskt verktyg som beskriver barnets språkmiljö genom automatisk analys. Videoanalysen sker manuellt av bedömare utifrån korta videoinspelningar av samspel mellan barn och förälder. Föreliggande studie syftade till att utvärdera dessa kartläggningsmetoders pålitlighet i mätning av verbala turtagningar. Vidare syftade studien till att undersöka eventuella mönster mellan antal verbala turtagningar i hemmiljö och strukturerad miljö. Fyra familjer med barn i åldrarna 0:26–7:3 månader deltog. Barn och förälder samspelade under en strukturerad leksituation som analyserades med LENA och videoanalys. Varje familj gjorde även en heldagsinspelning med LENA i hemmiljö. Antal verbala turtagningar i den strukturerade leksituationen analyserades av två bedömare med videoanalys. Interbedömarreliabilitet räknades ut och en kvalitativ bedömning genomfördes på intervall med interbedömarreliabilitet <80 %. Samstämmigheten mellan videoanalysen och LENA beräknades gällande den strukturerade leksituationen. Vidare jämfördes antal turtagningar mätt med LENA i hemmiljö och strukturerad miljö. Resultatet visade på en hög interbedömarreliabilitet i videoanalysen och i den kvalitativa bedömningen identifierades försvårande aspekter. Samstämmigheten mellan videoanalysen och LENA var måttlig. Antalet turtagningar var genomgående högre i den strukturerade leksituationen jämfört med hemmiljö. Studien tyder på att videoanalysen är en pålitlig metod. Dock identifierades försvårande aspekter som bör åtgärdas för att öka mätningens tillförlitlighet. Studien bekräftar tidigare forskning som visat på begränsningar gällande LENA:s mätning av turtagningar hos unga spädbarn. Resultatet tyder på att det sker fler turtagningar i strukturerad miljö än i hemmiljö. För att säkerställa studiens resultat krävs fortsatta studier.

Syftet med uppsatsen ”Medmänsklighet och Gudomligt Beskydd – en receptionsestetisk studie av Maria (Återkomsten) och Skyddsmantelmadonnan” är att ur ett receptionsestetiskt perspektiv närma sig skulpturerna Maria (Återkomsten) av Anders Widoff och Skyddsmantelmadonnan av Lena Lervik. Skulpturerna finns i och i anslutning till Uppsala respektive Lunds domkyrka. Genom receptionsestetikens metod där man tittar på ett konstverks interna faktorer som rör verkets inre organisation samt externa faktorer såsom platsen där konstverken är placerade, andra konstverk som relaterar till verket, en myt eller berättelse som är viktig för förståelsen av konstverken etcetera, rör sig uppsatsen fram mot en diskussion kring vem som är verkens implicite betraktare, dvs. ideala betraktare. Uppsatsen ämnar även diskutera hur jungfru Maria gestaltas i de berörda skulpturerna: vilken bild konstverken ger av Maria. Metoden för att diskutera vem som är verkens implicite betraktare och hur betraktaren aktiverar konstverken i relation till platserna är besök på de platser där konstverken finns för att i denna miljö möta verken och läsning av relevant litteratur. Slutsatsen är att skulpturerna är medvetet placerade i anslutning till kyrkorum och att platserna utgör en viktig dialog med konstverken. Skulpturerna ger väldigt olika bilder av jungfru Maria: Maria (Återkomsten) gestaltar Marias mänskliga sida och Skyddsmantelmadonnan är mer av en gudinnegestalt, en Moder Jord och urmoder som beskyddar mänskligheten. Verkens implicite betraktare är någon som vistas på platsen och möter verken med en öppenhet; verken har båda en öppenhet i framförallt ansiktsuttryck som öppnar för olika tolkningar. Den implicite betraktaren – i meningen den ideala betraktaren – är en människa med en öppenhet för en andlig dimension men är inte nödvändigtvis troende. Betraktaren behöver inte ha kunskap om vem jungfru Maria är, verkens tillkomsthistoria, verk som kan tänkas relatera till skulpturerna etcetera men det kan fördjupa upplevelsen. / The purpose of the essay "Humanity and Heavenly Protection – a Study of Mary (The Return) and the Protective Cloak Madonna Based on the Theory and Method of Reception Aesthetics" is to approach the sculptures Mary (The Return) by the artist Anders Widoff, and The Protective Cloak Madonna by the artist Lena Lervik. The sculptures are placed inside Uppsala Cathedral and outside Lund Cathedral respectively, and the study is based on the theory and method of reception aesthetics, where one looks at an artwork's internal factors that relate to the work's internal organization, as well as external factors, such as the situation of the work, relating works, or myths or stories that are important to understanding the work. Through this theory, a discussion about the implicit (ideal) beholder of the works takes place. Furthermore, the essay aspires to discuss the representation of Virgin Mary in the sculptures: what images of her the artworks present. The discussion of the implicit beholder, as well as the question of how locations affect the viewer’s activation of the works, was based on visits to the sites, as well as the study of literature on the artworks and the theory used.  The conclusion is that the sculptures are intentionally placed in the vicinity of cathedrals, and that the sites constitute an important dialogue with the artworks. The sculptures present very different images of the Virgin Mary: Mary (The Return) embodies Mary's human side, while the Protective Cloak Madonna is more of a Goddess figure, a Mother Earth and ancestor who protects humanity. The implicit beholder of the works is someone who visits the sites and encounters the works with an open mind; the sculptures have openness to them, especially in the facial expressions that invite different interpretations. The implicit (ideal) beholder is a person with an open mind to a spiritual dimension, but is not necessarily a Christian. The viewer does not need to know who Virgin Mary is, nor the history of the artworks or relating works, even though such knowledge might deepen the experience.

During the 21st century, Society has again begun to focus its attention on working class literature and on issues related to social class. In the media contemporary working class literature is often mentioned as a distinct phenomenon. I my view, the meaning of this phenomenon have not been adequately formulated. The aim of this Master’s Thesis is to reconstruct, using a discourse oriented text analysis, a picture of how the contemporary working class literature is described in today’s society. This approach falls therefore within the framework of the Sociology of Literature and is based on the assumption that the discourse of working class literature is undergoing change. Utilizing an established definition of working class literature, I have created five nodal points around which I believe the discourse is mainly formed and changed. Links are then made to these points from chains of equivalence, based on essential ideas concerning the identities that have been ascribed to different subjects and objects. In order to show how the discourse is contextually constructed, the results are seen in relation to a discussion in contemporary research and literature about class society and the welfare state. My empirical data consists mainly of reviews and interviews in leading daily newspapers in Sweden concerning five writers who have published novels between 1999 and 2007 and who have been associated with contemporary working class literature. These writers are Lena Andersson, Torbjörn Flygt, Tony Samuelsson, Susanna Alakoski and Åsa Linderborg. The results show that the working class writer is a “class traveller”, who today holds a prominent position within the literary public sphere. The main purpose of the literature is to criticize the class society of today and to make it more visible. The novels reflects findings from social science research showing that the modern welfare state is a segregated and unequal society where the losers mainly consist of the unemployed and immigrants who often live in suburbs that were built during the million dwellings program. They also show today’s working class that primarily consist of people within the caring and service sectors and therefore largely are women. / Uppsatsnivå: D

Already in the late 1970´s it became clear that the traditional catalogs in libraries were not suited for children, neither their interests nor their way expressing themselves were accounted for. The goal of this thesis is to investigate if and how children’s OPACs (Open public access catalogs) interface design is at present adapted to the presumed audience of children. My method consists of literature studies and an investigation on the graphical interfaces in OPACs for children, according to the five criteria formulated by childrens library consultant Lena Lundgren and IT-consultant Kia Gumbel. The aims are to find out: a) what requirements for children’s OPAC interfaces and their usability are defined in literature and b) what the actual (real) features of the children’s OPAC interfaces are. What interests me, regarding the graphical interfaces, is the actual appearance seen by the children, and partly the interactivity supplied by the OPACs. Using the criteria of Lundgren and Gumbel, I analyse figures, the front page, key-words, the text and the quality appearing in the different OPACs. In conclusion, the graphical interfaces of the three OPACs for children are somewhat adapted for children according to the Lundgren/Gumbel criteria. By using for example more user-polls, individualized graphical interfaces and reference groups consisting of children, the graphical interface for OPACs can be modified, and hopefully optimised, to take full account of the varied abilities of children. / Uppsatsnivå: C

The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. Degradation of this land-derived material in the sea would result in the production of dissolved carbon dioxide and may then add to the atmospheric carbon dioxide reservoir. Observations from the Siberian Arctic suggest that transfer of carbon from land to the marine environment is accelerating. However, it is not clear how much of the transported OC is degraded and oxidized, nor how much is removed from the active carbon cycle by burial in marine sediment. Using bulk geochemical parameters, total OC, d13C and D14C isotope composition, and specific molecular markers of plant wax lipids and lignin phenols, the abundance and composition of OC was determined in both dissolved and particulate carrier phases: the colloidal OC (COC; part of the dissolved OC), particulate OC (POC), and sedimentary OC (SOC). Statistical modelling was used to quantify the relative contribution of OC sources to these phases. Terrestrial OC is derived from the seasonally thawing top layer of permafrost soil (topsoil OC) and frozen OC derived from beneath the active layer eroded at the coast, commonly identified as yedoma ice complex deposit OC (yedoma ICD-OC). These carbon pools are transported differently in the aquatic conduits. Topsoil OC was found in young DOC and POC, in the river water, and the shelf water column, suggesting long-distance transport of this fraction. The yedoma ICD-OC was found as old particulate OC that settles out rapidly to the underlying sediment and is laterally transported across the shelf, likely dispersed by bottom nepheloid layer transport or via ice rafting. These two modes of OC transport resulted in different degradation states of topsoil OC and yedoma ICD-OC. Terrestrial CuO oxidation derived biomarkers indicated a highly degraded component in the COC. In contrast, the terrestrial component of the SOC was much less degraded. In line with earlier suggestions the mineral component in yedoma ICD functions as weight and surface protection of the associated OC, which led to burial in the sediment, and limited OC degradation. The degradability of the terrestrial OC in shelf sediment was also addressed in direct incubation studies. Molecular markers indicate marine OC (from primary production) was more readily degraded than terrestrial OC. Degradation was also faster in sediment from the East Siberian Sea, where the marine contribution was higher compared to the Laptev Sea. Although terrestrial carbon in the sediment was degraded slower, the terrestrial component also contributed to carbon dioxide formation in the incubations of marine sediment. These results contribute to our understanding of the marine fate of land-derived OC from the Siberian Arctic. The mobilization of topsoil OC is expected to grow in magnitude with climate warming and associated active layer deepening. This translocated topsoil OC component was found to be highly degraded, which suggests degradation during transport and a possible contribution to atmospheric carbon dioxide. Similarly, the yedoma ICD-OC (and or old mineral soil carbon) may become a stronger source with accelerated warming, but slow degradation may limit its impact on active carbon cycling in the Siberian Shelf Seas. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Manuscript.

Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. Despite the global importance of this region the behavior of the, by far largest fraction of the OCter, the dissolved organic carbon (DOC) in Arctic and sub-arctic estuaries is still a matter of debate. This thesis describes data originating from field cruises in Arctic and sub-arctic estuaries and coastal areas with the aim to improve the understanding of the fate of OCter in these areas, with specific focus on DOC. All presented studies indicate that DOCter and terrestrially derived particulate organic carbon (POCter) are subjected to substantial degradation in high-latitude estuaries, as shown by the non-conservative behavior of DOC in the East Siberian Arctic Shelf Seas (ESAS) (paper I) and the even more rapid degradation of POC in the same region (paper II). The removals of OCter in Arctic shelf seas were further supported by multiple isotope studies (paper III and IV), which showed that a use of 13C/12C in both OC and DIC, together with 34S/32S is a powerful tool to describe the sources and fate of OCter in estuaries and coastal seas. High-latitude estuaries play a key role in the coupling between terrestrial and marine carbon pools. In contrast to the general perception, this thesis shows that they are not only transportation areas for DOCter from rivers to the ocean, but are also active sites for transformation, degradation and sedimentation of DOCter, as well as for POCter. In a rapidly changing climate, the importance of these areas for the coupling between inorganic and organic carbon pools cannot be underestimated. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 1: In press.

Syfte med uppsatsen har varit att undersöka färgens och gestikens påverkan på altarskåpets iscensättning av berättelserna och därmed även budskapet. Uppsatsen har ett bildsemiotiskt perspektiv som en utgångspunkt. Materialet för undersökningen är ett flandriskt altarskåp från Skånela kyrka som finns idag i Uppsala domkyrka. Skåpet är tillägnat Joakim och Sankta Anna. Undersökningen har avgränsats till att enbart analysera de sex skulpterade scenerna i korpusen. Analyserna har utförts genom en formell beskrivning och diskussion med hjälp av Lena Liepes lågikonografiska analys och med Norbert Ottos trestegsmetod för gestfunktioner. Lena Liepes metod och teori används som underlag för undersökningen. Undersökningen ansluter till Virginia Nixons forskningsarbete om Jesu mormor i kyrkokonsten. Det har konstaterats att färg- och gestikanalyserna möjliggör en nyanserad tolkning. Undersökningen har visat att färgen och gestiken är ett påverkningsmedel i syfte att leda betraktaren mot ett dolt budskap i bilden. Och att det finns en koppling mellan Skånelaskåpets budskap och den medeltida kvinnofientlighet som var rådande då. Annaskåpet innehåller budskap som präglas av den dåvarande barn- och kvinnosyner. / Purpose of this essay has been to examine the color's and gesticulation's impact on the altarpiece staging of the stories and thus the message. The essay has a semiotic perspective as a starting point. The material for the study is a flemish altarpiece from Skånela church that exists today in Uppsala Cathedral. The altarpiece is dedicated to Joachim and St. Anne. The study has been limited to only analyze the six sculptured scenes in the corpus. The analyzes have been performed through a formal description and discussion by Lena Liepes low iconographycal analysis and with Norbert Otto's three-step approach for gesture features. Lena Liepe's method and theory was used as a basis for the investigation. The study connects to Virginia Nixon's research on Jesus' grandmother in church art. It was found that the color and gesticulation analyzes enables a nuanced interpretation. The investigation has shown that the color and gestures are an actuation in order to lead the viewer towards a hidden message in the picture. And that there is a link between Skånela altarpiece's messages and the medieval misogyny that prevailed then. Anne-altarpiece contains messages that are characterized by the contemporary child and female visions.
