High-impact, localized intense rainfall episodes represent a major socio-economic problem for societies worldwide, and at the same time these events are notoriously difficult to simulate properly in climate models. Here, the authors investigate how horizontal resolution and model formulation influence this issue by applying the HARMONIE regional climate model (HCLIM) with three different setups; two using convection parameterization at 15 and 6.25 km horizontal resolution (the latter within the “grey-zone” scale), with lateral boundary conditions provided by ERA-Interim reanalysis and integrated over a pan-European domain, and one with explicit convection at 2 km resolution (HCLIM2) over the Alpine region driven by the 15 km model. Seven summer seasons were sampled and validated against two high-resolution observational data sets. All HCLIM versions underestimate the number of dry days and hours by 20-40%, and overestimate precipitation over the Alpine ridge. Also, only modest added value were found of “grey-zone” resolution. However, the single most important outcome is the substantial added value in HCLIM2 compared to the coarser model versions at sub-daily time scales. It better captures the local-to-regional spatial patterns of precipitation reflecting a more realistic representation of the local and meso-scale dynamics. Further, the duration and spatial frequency of precipitation events, as well as extremes, are closer to observations. These characteristics are key ingredients in heavy rainfall events and associated flash floods, and the outstanding results using HCLIM in convection-permitting setting are convincing and encourage further use of the model to study changes in such events in changing climates.

The study concerns the new educational activities that emerge within the deregulated school system at the beginning of the 21st century. Which ideas guide the work? How is the activity formed? What does one hope to achieve? The aim of the thesis is to explore these educational practices in one of the larges independent schools in Sweden – Kunskapsskolan. The study was based upon a sociocultural perspective on learning and on twenty situated interviews with seven principals. Tools central for the activity in Kunskapsskolan were used as basis for the interviews. A qualitative analysis has been used; one of the methods for analysis applied is phenomenography. The study shows how the school, with the help of centrally developed tools, organised the teaching and the environments for learning that were implemented in all schools of the company. Individually organised teaching is the foundation for all teaching, where the students are expected to be self-regulated and self-correcting and use the tools provided for their learning. With regards to the students’ learning, the teachers’ role is mainly related to individual tutorial conversations. Thereby the tools intended to create freedom and control for the students, also create problems and obstacles. Students who do not learn to use the tools have difficulties in managing their studies. The new tools also affect the teachers’ work. In comparison with other schools, the teachers are expected to submit to the educational model and a centrally controlled planning. The teaching is centrally planned in subject specific stages or subject integrated courses. Teachers can influence the central planning by working collaboratively in teacher teams but not individually. The main commission of the teachers is to follow the educational model decided by the company. In comparison with the traditional school, both teachers and students are given new roles. When learning is individually organised for the students, the teachers are expected to develop their knowledge collectively. According to the results, both students and teachers have different approaches to the system – they can submit to the system or approach it in a more independent and reflective way.

The aim of this study has been to revaluate Bronze Age society using rock art as an archaeological material. It has also sought to question certain prevailing interpretative trends within the research of rock art; ascribing it as ritual practices, expression of a social elite and the adoption of symbols from cultures along the Mediterranean Sea. This has chiefly been made possible through the application of Slavoj Žižeks ideas about the ideological fantasy and the sublime object of ideology. The thesis proposes a connection between art and ideology. A selected sampling of rock carvings from three areas in Sweden has been made in order to further investigate the relationship between different figurative motives both at a regional level, as well as a local. This study claims that rather than having been under the control of an elite, rock art has been accessible for the majority of the population both to produce and view. The depiction of human representation as rock carving does not depict a clear social stratification. It is also argued that the idea of images displayed on the rocks having roots in the imagery of Mediterranean civilizations is a construct of current western ideology, as the symbolic connection between the cultures is tenable at best, according to this study.

Eviction from housing is an institutionalized social process affecting millions in the western world, but very little is understood about its impact on people’s lives. Guided by George Brown and Tirril Harris’s landmark sociological research on disruptive life events, together with evidence that home is an important ‘place’, this study aims to contribute to an understanding of eviction’s fallout by considering depression as a potential outcome. Taking advantage of unique data on all evictions in Sweden and linking to longitudinal registers, this study seeks to determine whether working-age adults facing imminent eviction in 2009 had a greater risk of depression in the following year compared, using penalized maximum likelihood logistic regressions, to a control group randomly drawn from the Swedish population. Results indicate that imminent eviction is significantly associated with subsequent depression, even accounting for a range of social, economic, geographic and behavioral characteristics. Contrary to expectations, the findings are not robust for gender differences. Recent mental illness is the only control variable significantly moderating the association of interest, which remains significant regardless of illness history. The results provide grounds for treating eviction as a disruptive life event in its own right.

The aim of this research is to provide insight into how middle school learners experience an inclusive multicultural learning environment. Increasing diversity is challenging European educational systems, which have the arduous task to foster inclusion of learners with diverse educational needs. In order to explore the participants’ descriptions, a qualitative approach based on semi-structured interviews with six learners was employed. Learners’ positions in the educational scenery are central and unique; they are the main experts on their own situations and therefore precious contributors to educational research. Results have been discussed according to a sociocultural perspective. The analysis of my data suggests that the learners perceive their inclusive environment as beneficial. Moreover, they perceive their cultural diversity as strength, reckon social interaction and teamwork with peers as favorable conditions for learning, feel competent in multicultural communication and believe that respect and acceptance towards others are necessary common values. Some implications of multiculturalism in special education are discussed according to the results of a recent European study, which shows that in all the participating European countries, Sweden included, there is a consistent discrepancy in the proportions of learners with immigrant background within special education. Assessment methods developed for mono-cultural learners appear to be a valid reason why multicultural learners are over-or under-represented in special education. Research also shows that inclusion of diversity in educational environment enables the development of social skills in all learners.

Both long-term environmental changes such as those driven by the glacial cycles and more recent anthropogenic impacts have had major effects on the past demography in wild organisms. Within species, these changes are reflected in the amount and distribution of neutral genetic variation. In this thesis, mitochondrial and microsatellite DNA was analysed to investigate how environmental and anthropogenic factors have affected genetic diversity and structure in four ecologically different animal species. Paper I describes the post-glacial recolonisation history of the speckled-wood butterfly (Pararge aegeria) in Northern Europe. A decrease in genetic diversity with latitude and a marked population structure were uncovered, consistent with a hypothesis of repeated founder events during the postglacial recolonisation. Moreover, Approximate Bayesian Computation analyses indicate that the univoltine populations in Scandinavia and Finland originate from recolonisations along two routes, one on each side of the Baltic. Paper II aimed to investigate how past sea-level rises affected the population history of the convict surgeonfish (Acanthurus triostegus) in the Indo-Pacific. Assessment of the species’ demographic history suggested a population expansion that occurred approximately at the end of the last glaciation. Moreover, the results demonstrated an overall lack of phylogeographic structure, probably due to the high dispersal rates associated with the species’ pelagic larval stage. Populations at the species’ eastern range margin were significantly differentiated from other populations, which likely is a consequence of their geographic isolation. In Paper III, we assessed the effect of human impact on the genetic variation of European moose (Alces alces) in Sweden. Genetic analyses revealed a spatial structure with two genetic clusters, one in northern and one in southern Sweden, which were separated by a narrow transition zone. Moreover, demographic inference suggested a recent population bottleneck. The inferred timing of this bottleneck coincided with a known reduction in population size in the 19th and early 20th century due to high hunting pressure. In Paper IV, we examined the effect of an indirect but well-described human impact, via environmental toxic chemicals (PCBs), on the genetic variation of Eurasian otters (Lutra lutra) in Sweden. Genetic clustering assignment revealed differentiation between otters in northern and southern Sweden, but also in the Stockholm region. ABC analyses indicated a decrease in effective population size in both northern and southern Sweden. Moreover, comparative analyses of historical and contemporary samples demonstrated a more severe decline in genetic diversity in southern Sweden compared to northern Sweden, in agreement with the levels of PCBs found.

I denna uppsats analyseras två föreläsningar genomförda av Studie- och språkverkstaden på Stockholms universitet. Syftet är att undersöka i vilken utsträckning föreläsningarna kan bidra till studenters akademiska skriftspråkliga progression. Materialet, som består av observationer, enkätsvar, intervjuer och mejl, har analyserats med metoder från medierad diskursanalys (MDA, Scollon & Scollon 2004). I undersökningen deltar 30 studenter, den språkinstitution som studenterna är inskrivna på samt Studie- och språkverkstaden. Resultaten visar att faktorer som interaktionsordning, historisk kropp och diskurser har stor betydelse för hur föreläsningarna uppfattas och används av studenterna. Hur studenterna motiverar sitt handlande beror på vem som uppfattas som social aktör både före, under och efter föreläsningarna; hur interaktionsordningen ser ut har betydelse för utfallet av antal studenter som deltar på föreläsningarna; hur en diskurs presenteras har betydelse för hur studenterna motiverar sitt handlande under föreläsningen; förväntningar på förutsättningar och förkunskaper ser olika ut hos språkinstitutionen och studenterna: de yngre studenterna relaterar positivt sina akademiska erfarenheter till läroplanen Gy 2011, språkinstitutionen signalerar brist i förutsättningar och förkunskaper relaterade till Gy 2011; föreläsningarna har höjt eller aktualiserat studenternas medvetande om den akademiska diskursen, och slutligen konstateras att studenternas tidigare akademiska erfarenhet inte har någon större inverkan på utfallet av föreläsningarna.

Title: Swedish Match-En kvalitativ studie om butikskonceptet  Author: Adam Waernér/Erik Rehnberg  Supervisor: Jonas Jonasson  Key Words: Communication, Branding, Culture, PR, Advertisement  Purpose: The purpose of this research is to understand the background of the launch of Swedish Match´s stores. Because of the strict laws against marketing of tobacco products in Sweden, we believe that the stores are an interesting way of approaching a new branding and communication strategy in the tobacco industry.  Research questions: What´s the background to the launch of Swedish Match Stores? What´s the stores impact on Swedish Match image? How do Swedish Match Stores impact the cultural status of snus? In what ways do the cultural trends impact the snus market?  Theory: In this study we have applied theories concerning culture, communication, branding, PR and advertisement. Methodology: We have chosen to apply a qualitative method on this research. The method consists of three different methods: one focus group, one observation study which consists of two different observations both in the Gothenburg store and the store in Stockholm, the last method is an online interview with the public relations officer of Swedish Match in Sweden. Because of the chosen method´s we hope to bring three different perspectives to the  study: From the customers perspective, from our own perspective and finally from the company´s perspective.  Findings: Through this research we discovered that the stores do not only work as a communication strategy for Swedish Match. The store as a phenomenon also works in the aspect of branding, PR and also gives a higher cultural status to snus. Through our own observation and the focus group we came to the conclusion that the stores in terms of image of Swedish Match implements a cultural aspect of swedishness to the company, as well as a more modern and new take on snus. We also came to the conclusion that snus is a cultural phenomenon that is impacted of other contemporary trends, such as gastronomic trends and the increased popularity of small scale exclusivity.

We investigated whether a physiological marker of cardiovascular health, pulse pressure (PP), and age magnified the effect of the functional COMT Val158Met (rs4680) polymorphism on 15-years cognitive trajectories [episodic memory (EM), visuospatial ability, and semantic memory] using data from 1585 non-demented adults from the Betula study. A multiple-group latent growth curve model was specified to gauge individual differences in change, and average trends therein. The allelic variants showed negligible differences across the cognitive markers in average trends. The older portion of the sample selectively age-magnified the effects of Val158Met on EM changes, resulting in greater decline in Val compared to homozygote Met carriers. This effect was attenuated by statistical control for PP. Further, PP moderated the effects of COMT on 15-years EM trajectories, resulting in greater decline in Val carriers, even after accounting for the confounding effects of sex, education, cardiovascular diseases (diabetes, stroke, and hypertension), and chronological age, controlled for practice gains. The effect was still present after excluding individuals with a history of cardiovascular diseases. The effects of cognitive change were not moderated by any other covariates. This report underscores the importance of addressing synergistic effects in normal cognitive aging, as the addition thereof may place healthy individuals at greater risk for memory decline.

A relevant subject in our globalized world concerns the relationship between language and identity, specifically amongst migrant youngsters’ experience of group belonging. This study therefore focused on how adolescents born to foreign parents in Sweden, perceived their multilingualism as part of their identity formation. I also aimed to include how socio-economic aspects could affect the process of identity construction. Thus, the investigation was performed with seventh grade students at a primary school located in the Stockholm suburb Bredäng. The methods consisted of a questionnaire, which was completed by the entire class and a group interview where six students participated. The results revealed that students adapted their language use based on the context, but Swedish was used most habitually. The informants viewed their multilingualism as beneficial but yet fully aware of the linguistic ideologies functioning in society. By combining their minority and majority language, the students were left with different ethnic identities and had diverse interpretations of what it meant to be Swedish. Even though all of them perceived themselves to have multiple ethnic identities, this was not solely seen positively. The issue of belonging was raised and the students claimed to be outcasts everywhere. However, the results differed depending on whether the students were born in Sweden or not. Also, most of them struggled with the process of assumed and ascribed identities, since they perceived themselves to be Swedish but experienced that society valued them as immigrants. Lastly, the study revealed that there were connections between their multilingualism and social mobility as the relationship towards the motherland was highly prioritized even with low levels of economic capital.

Intercultural competence (IC) as an essential part of conceptualization of the cultural dimension in FLT has been promoted by educationalists as the most preferred type of competence. One of the challenges of incorporating IC into FLT is to move from the recognition of IC as a model of teaching (Byram, Nichols and Stevens, 2001) to the development of practical applications. This can be due to the fact that teachers do not have sufficient knowledge of the theory behind the concept and consequently, have difficulties to implement the curriculum requirements with regards to IC into their teaching. The purpose of this study was to investigate how teachers of English in upper secondary schools in Sweden interpret the concept of IC and, accordingly, what is their view of culture in English language teaching. In order to answer the research question, I used an exploratory investigation by adopting a qualitative research method in form of semi-structured interviews. The results are similar to the previous studies (Lundgren, 2002; Larzén, 2005) and suggest that teachers lack theoretical background and central guidance with regards to IC and do not always integrate language and culture into an intercultural model of the English language pedagogy.
