    The international diffusion of new chemical entities: A cross-national study of the determinants of differences in drug lag1990Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The two main objectives of this thesis are to make a general contribution to the understanding of the international diffusion of new chemical entities (NCEs) and to improve the research methods by applying econometric methodology.

    The study is based on a data base including all 553 NCEs introduced in Sweden during the period 1960-1987 and their introductions in France, West Germany, Italy, the United Kingdom, the United States and Norway. A complementary data base covering 11 countries for the period 1970-1983 is also examined.

    Large differences are found between the countries regarding the diffusion of NCEs - both in the number of NCEs that are diffused to the countries (level of diffusion) and in the time needed for the NCEs to diffuse (rate of diffusion). There is also a general tendency for an increasing amount of time to be needed for the NCEs to diffuse. Econometric methodology is applied in the search for the determinants of the rate of diffusion. The three earlier models of the rate of diffusion are all rejected and two new models are constructed, one Swedish and one international. In these models the regulation-related variables are found to have the largest influence on the rate of international diffusion of NCEs.

    At the end of the thesis, policy implications of the results and prospects for the future are discussed.

    Determination of Volatile Sulfur Compounds in Air and other Gas Matrices: Development and Applications of Solid-Phase Microextraction2003Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Volatile sulphur compounds (VSCs) are frequently emitted during bioindustrial activities, such as production of biogas, sewage treatment, landfilling, pulpmilling, and the slaughtering of animals and meat processing. VSCs are reactive and malodorous, and they can also be detrimental to human health, therefore it is of great interest to be able to analyze these compounds.

    However, the standard techniques that are now available for determination of VSCs entail detection limits that in some cases exceed the odor thresholds, and, what is more, they require the use of solvents and toxic reagents. In addition, a single standard method does not exist that can be used to analyze all the VSCs that are most often associated with bioindustrial processes.

    In the present studies, a technique based on solid-phase microextraction (SPME) was developed for analysis of the VSCs that are commonly found in the bioindustry. The method could even be applied to very complex gas matrices representing point-source emissions of these compounds in amounts below their odor thresholds. Furthermore, the procedure constitutes an improvement compared to the other techniques employed to determine VSCs, because SPME is less time-consuming, it does not require the use of solvents or other chemicals, and it can extract all the compounds simultaneously. The potential of applying SPME for time-weighted average sampling of VSCs was also investigated. These experiments showed that the connnercially available fiber coating with the highest affmity for VSCs (i.e., Carboxen-polydimethylsiloxane)could achieve accurate determination of dimethyldisulfide, whereas use of thatcoating to collect the other compounds was highly influenced by externalparameters that are subject to variation. This work also included investigationsof several important aspects of SPME analysis of VSCs, such as the choice offiber coating, artifact formation, and the impact of various parameters on theextraction.

    The current results demonstrate that the SPME methodology that was developed can be used to determine VSCs in different matrices and contexts within the bioindustry. More precisely, the technique was successfully employed for the following purposes: to determine background levels ofVSCs to which workers were exposed; to monitor VSC emissions during the biogas process; to supervise the quality of produced biogas; to investigate the efficiency of processes used for abatement of VSCs; and to ascertain the cause of odor problems.

    Abstract [en]

    A method was developed for the simultaneous determination of the following nine volatile sulfur compounds in gas samples: carbon disulfide, carbonyl sulfide, ethyl sulfide, ethyl methyl sulfide, hydrogen sulfide, isopropanethiol, methanethiol, methyl disulfide and methyl sulfide. The target compounds were preconcentrated by solid-phase microextraction (SPME) and determined by gas chromatography combined with mass spectrometry. Experimental design was employed to optimize the extraction time and temperature and concurrent detection of the nine compounds was achieved by using an SPME fiber coated with Carboxen-polydimethylsiloxane (75 ╡m). Detection limits ranged from 1 ppt (v/v) for carbon disulfide to 350 ppt (v/v) for hydrogen sulfide and calibration functions were linear up to 20 ppb (v/v) for all the compounds investigated.

    Abstract [en]

    Procedures were assessed for quantifying nine volatile sulfur compounds found in complex gaseous samples collected at a biogas-production plant and a sewage treatment plant. The target compounds were extracted by solid-phase microextraction (using the 75-╡m Carboxen-polydimethylsiloxane fiber coating) at 22░C for 20 min, and analyzed by GC-MS. Detection limits ranged between 1 pptv (v/v) for carbon disulfide and 470 pptv (v/v) for hydrogen sulfide. High amounts of organic compounds were found during full-scan analysis of the samples and standard additions to individual sub-samples revealed that the analysis was subject to matrix effects. However, the functions obtained by standard additions were still linear and quantification was possible for all the compounds tested except hydrogen sulfide. No detectable losses were observed during storage in the sampling containers, made of Tedlar film, over a storage period of 20 h. However, water permeated through the walls and the relative humidity in the bag increased during storage until it reached the ambient level. Finally, it was shown that the drying agent, CaCl2, caused no detectable losses of any of the compounds. ⌐ 2002 Elsevier Science B.V. All rights reserved.

    Abstract [en]

    The present study was conducted to develop a rapid, matrix-independent technique for simultaneous analysis of nine different volatile sulfur compounds (VSCs) in complex gas matrices.The potential of using solid-phase microextraction (SP:ME) in this context was investigated, and, to achieve the best sensitivity and avoid artifact formation and competitive adsorption, pel'formance ofthe following fiber coatings was tested: Carboxen/polydimethylsiloxane (CARIPDMS),divinylbenzene/ polydimethyl-siloxane (DVBIPDMS), and Carboxen/divinylbenzene/polydimethylsiloxane (CAR/DVBIPDMS). The optimal injector temperature and desorption time for each fiber were dete1n1ined by experimental design. The samples analyzed were collected in Tedlar bags at a biogas facility and a sewage treatment plant to represent background levels and point-source emissions. The samples were subsequently dried over CaClz and preconcenti·ated bySPME, and the target compounds were analyzed by GC-MS. CARIPDMS induced the lowest level of artifact formation and initially also exhibited the broadest range of linear adsorption kinetics. Anextraction time of 2.5 min gave no matrix effects, despite the complexity of the samples, and the analytes were accurately quantified using extemal calibration curves below odor thresholds.Detection limits ranged from 0.008 (CS2) to 2.5 (H2S) ppbv, and the relative standard deviation was 4-16%.

    Abstract [en]

    The extraction of pure hydrogen from the fermentation of household waste by a mixed anaerobic bacterial flora is demonstrated. Simulated household waste (600 g) was fermented in a bioreactor, which was continuously sparged with nitrogen (30 ml/min) fed in from the bottom. The gas stream from the biorector passes through a sulphide trap (ZnO) and then through a heated palladium-silver membrane reactor to separate hydrogen from the gas stream. In this way, waste remediation and biological hydrogen production is combined in a process where a large proportion of the hydrogen produced can be collected, free of other gaseous species from the fermentation. © 2001 International Association for Hydrogen Energy.

    2003 (English)In: Analytical Chemistry, ISSN 0003-2700, E-ISSN 1520-6882, Vol. 75, no 11, p. 2626-2632Article in journal (Refereed) Published
    Abstract [en]

    The potential of solid-phase microextraction (SPME) for time-weighted average (TWA) sampling of volatile sulfur compounds in air at ppb concentrations was investigated. The target compounds (hydrogen sulfide, methanethiol (MeSH), ethanethiol (EtSH), dimethyl sulfide (Me2S), and dimethyl disulfide (Me2S2)) were extracted using SPME with a Carboxen-poly(dimethylsiloxane) fiber coating, and diffusion was controlled by keeping the fiber retracted within the needle of the sampling device. The effects of several important experimental variables (air velocity, direction of air flow, analyte concentration, humidity, temperature, extraction time) were studied. The uptake by the fiber was not affected by the direction of the air flow or the air velocity. The effects of concentration, humidity, temperature, and extraction time were examined in experiments with a central composite face design. The results showed that all or most of the investigated parameters had a significant impact on the uptake rates of H2S, MeSH, EtSH, and Me2S, which invalidated time-weighted average sampling of these compounds by SPME under the tested conditions. Moreover, reverse diffusion of H2S, MeSH, and EtSH occurred at 40% relative humidity. For Me2S2, the uptake rate had a variation of only 8% within the whole experimental domain, and the experimental value derived for the uptake rate was consistent with the theoretical value. This result was confirmed by comparative analyses of industrial samples by the standard addition method. Therefore, SPME appears to be a suitable technique for TWA sampling of Me2S2 using the Carboxen-poly(dimethylsiloxane) fiber coating. Finally, in an investigation of potential losses during storage of the fiber, no significant losses of the target compounds were detected after 3 days at -80 °C.

    Abstract [en]

    Volatile sulfur compounds (VSCs) in biogas originating from a biogas production plant and from a municipal sewage water treatment plant were identified. Samples were taken at various stages of the biogas-producing process, including upgrading the gas to vehicle-fuel quality. Solid-phase microextraction was used for preconcentration of the VSCs, which were subsequently analyzed using gas chromatography in combination with mass spectrometry. Other volatile organic compounds present also were identified. The most commonly occurring VSCs in the biogas were hydrogen sulfide, carbonyl sulfide, methanethiol, dimethyl sulfide, and dimethyl disulfide, and hydrogen sulfide was not always the most abundant sulfur (S) compound. Besides VSCs, oxygenated organic compounds were commonly present (e.g., ketones, alcohols, and esters). The effect of adding iron chloride to the biogas reactor on the occurrence of VSCs also was investigated. It was found that additions of 500-g/m3 substrate gave an optimal removal of VSCs. Also, the use of a prefermentation step could reduce the amount of VSCs formed in the biogas process. Moreover, in the carbon dioxide scrubber used for upgrading the gas, VSCs were removed efficiently, leaving traces (ppbv levels). The scrubber also removed other organic compounds.

    Haverier i social barnavård? Fem fallstudier2001Book (Other academic)
    Abstract [sv]

    HAVERIER i social barnavård är lyckligtvis mycket ovanliga. I detta arbete analyseras fem fall som alla vid någon tidpunkt har utvecklats på ett olyckligt sätt. De olika fallen ger tillsammans en bred belysning av dilemmor och möjligheter i socialt och psykiatriskt arbete med utsatta barn. Genom att analysera olika vändpunkter i fallen diskuteras både haverier och god praktik. Läsaren kan själv ta ställning: Vad är ett haveri? Hur kan haverier undvikas? Det finns också rikligt med stoff för debatt kring barnets bästa, barns rättigheter, och mediernas och allmänhetens ansvar. Boken har alla förutsättningar att engagera både den intresserade allmänheten och journalister, liksom personer under utbildning eller fortbildning vid socialhögskolor, psykiatriutbildningar och jurist- eller polishögskolor. FALLSTUDIEN som metod har varit av avgörande betydelse inom hjärnforskningen och annan medicinsk forskning. Inom samhällsvetenskaperna har den däremot varit försummad. I denna bok illustreras olika angreppssätt genom fem olika typer av fall. Dessutom presenteras teori kring fallstudier och berättande, liksom metodiska synpunkter på fallstudien som forsknings- och utredningsmetod.

    Bilingual and Monolingual Children's Narration: Discourse Strategies and Narrative Styles1997Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis investigates twenty bilingual and twenty monolingual 6-year-old preschool children's discourse strategies and narrative styles. It is theoretically based on an interdiciplinary framework combining theories of narration with discourse theories. Methodologically, the study draws on micro-analyses of children's spontaneous sharing time narrations, on the one hand, and elicited retellings of a fable, on the other. A new method was developed for analysing Labovian story points from a collaborative perspective: differentiating between child contributions, teacher contributions, and joint contributions. Moreover, all children were interviewed about their literary repertoires and about narrative practices at home. It was found that children's vocabulary was closely linked to their literary repertoires and cultural habits. By calculating the repair:error ratio, the present study shows that there is a linear development in children's repair work, instead of an inverted U-curve as previously suggested. Language repairs were rare in both groups. The children primarily focused on meaning, not on linguistic form. However, there were more language errors in the bilingual group. Moreover, the bilingual group had a more restricted vocabulary. Yet, the findings reveal that narrative coherence was comparable in the monolingual and bilingual groups. In an analysis of participation during sharing time sessions, it was found that peer comments and child initiatives were more frequent in the monolingual group, and in specific preschool settings. Collaboration was investigated both in terms of teacher support, co-narration, and in  terms of indirect ways of collaborating, like the employment of communication strategies and self-repairs. It was found that bilingual children received  more collaborative support and employed more communication strategies than their monolingual peers.

    Land Cover Change in the Okavango River Basin: Historical changes during the Angolan civil war, contributing causes and effects on water quality2006Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    The Okavango river flows from southern Angola, through the Kavango region of Namibia and into the Okavango Delta in Botswana. The recent peace in Angola hopefully marks the end of the intense suffering that the peoples of the river basin have endured, and the beginning of sustainable decision-making in the area. Informed decision-making however requires knowledge; and there is a need for, and a lack of knowledge regarding basin-wide land cover (LC) changes, and their causes, during the Angolan civil war in the basin. Furthermore, there is a need for, and a lack of knowledge on how expanding large-scale agriculture and urban growth along the Angola-Namibia border affects the water quality of the river.

    The aim of this study was therefore to develop a remote sensing method applicable to the basin (with scant ground-truth data availability) to carry out a systematic historic study of LC changes during the Angolan civil war, to apply the method to the basin, to relate these changes to major societal trends in the region, and to analyse potential impacts of expanding large-scale agriculture and urban growth on the water quality of the river along the Angola-Namibia border.

    A range of remote sensing methods to study historic LC changes in the basin were tried and evaluated against reference data collected during a field visit in Namibia in October 2005. Eventually, two methods were selected and applied to pre-processed Landsat MSS and ETM+ satellite image mosaics of 1973 and 2001 respectively: 1. a combined unsupervised classification and pattern-recognition change detection method providing quantified and geographically distributed binary LC class change trajectory information and, 2. an NDVI (Normalised Difference Vegetation Index) change detection method providing quantified and geographically distributed continuous information on degrees of change in vegetation vigour. In addition, available documents and people initiated in the basin conditions were consulted in the pursuit of discerning major societal trends that the basin had undergone during the Angolan civil war. Finally, concentrations of nutrients (total phosphorous & total nitrogen), bacteria (faecal coliforms & faecal streptococci), conductivity, total dissolved solids, dissolved oxygen, pH, temperature and Secchi depth were sampled at 11 locations upstream and downstream of large-scale agricultural facilities and an urban area during the aforementioned field visit.

    The nature, extent and geographical distribution of LC changes in the study area during the Angolan civil war were determined. The study area (150 922 km2) was the Angolan and Namibian parts of the basin. The results indicate that the vegetation vigour is dynamic and has decreased overall in the area, perhaps connected with precipitation differences between the years. However while the vigour decreased in the northwest, it increased in the northeast, and on more local scales the pattern was often more complex. With respect to migration out of Angola into Namibia, the LC changes followed expectations of more intense use in Namibia close to the border (0-5 km), but not at some distance (10-20 km), particularly east of Rundu. With respect to urbanisation, expectations of increased human impact locally were observed in e.g. Rundu, Menongue and Cuito Cuanavale. Road deterioration was also observed with Angolan urbanisation but some infrastructures appeared less damaged by the war. Some villages (e.g. Savitangaiala de Môma) seem to have been abandoned during the war so that the vegetation could regenerate, which was expected. But other villages (e.g. Techipeio) have not undergone the same vegetation regeneration suggesting they were not abandoned. The areal extent of large-scale agriculture increased 59% (26 km2) during the war, perhaps as a consequence of population growth. But the expansion was not nearly at par with the population growth of the Kavango region (320%), suggesting that a smaller proportion of the population relied on the large-scale agriculture for their subsistence in 2001 compared with 1973.

    No significant impacts were found from the large-scale agriculture and urbanisation on the water quality during the dry season of 2005. Total phosphorous concentrations (with range: 0.067-0.095 mg l-1) did vary significantly between locations (p=0.013) but locations upstream and downstream of large-scale agricultural facilities were not significantly different (p=0.5444). Neither did faecal coliforms (range: 23-63 counts per 100ml) nor faecal streptococci (range: 8-33 counts per 100ml) vary significantly between locations (p=0.332 and p=0.354 respectively). Thus the impact of Rundu and the extensive livestock farming along the border were not significant at this time. The Cuito river on the other hand significantly decreased both the conductivity (range: 27.2-49.7 μS cm-1, p<0.0001) and the total dissolved solid concentration (range: 12.7-23.4 mg l-1, p<0.0001) of the mainstream of the Okavango during the dry season.

    Land cover changes during the Angolan civil war, contributing causes and effects on water quality were studied in this research effort. Many of the obtained results can be used directly or with further application as a knowledge base for sustainable decision-making and management in the basin. Wisely used by institutions charged with that objective, the information can contribute to sustainable development and the ending of suffering and poverty for the benefit of the peoples of the Okavango and beyond.

    Faser och teman i en hiphopares liv: Berättelser om hiphop som ungdomskultur2005Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    This is a narrative study of the hiphop culture as a youth culture. The aim has been to understand how and why young people in middle-sized Swedish towns become hiphopers and also how they look at themselves as members of the hiphop culture.

    The research methods applied are three focus group interviews and one single person interview. The participants are between 20 and 26 years. The hiphoper makes a kind of a career in the culture. To be able to make the career, the hiphoper is dependent of other people with better skills as well as of the society. The thoughts of the hiphopers in question can be summarized in four main themes: gender, attribute, genuine and battle.

    Inflytande och delaktighet: elevperspektiv på skolans demokrati2000Report (Other academic)
    Abstract [sv]

    Denna uppsats lyfter fram ungdomars syn på och erfarenheter av skolans demokrati. Det är elevernas situation som diskuteras. Hur ser skoldemokrati ut när den skildras i perspektiv av ungdomarnas eget vardagsliv? Mitt arbete tar upp inflytande och ansvarstagande för den enskilde eleven. Det fokuserar ungdomarnas syn på inflytande över undervisningens utformning och innehåll samt arbetsprocesser och arbetsmiljö. Jag bar vel att lyfta fram det reella inflytandet, oavsett om det är formellt eller informellt. Den förändrade synen på elevers rätt till inflytande i skolverksamheten har kontinuerligt uppmärksammats i rapporter och utredningar. I mitt sökande efter material har jag avgränsat tidsperioden att gälla de sista 20-25 åren.

    Above All Else, Do Not Snitch: Constructing Criminal Identities and Negotiating Masculinities in Agression Replacement Training2008Article in journal (Other academic)
    Abstract [en]

    In the present article, the issue of snitching is analysed as part of a convict code, drawn upon by young men detained for assessment at a youth detention home and participating in Aggression Replacement Training (ART). ART is viewed in light of other research on peer interventions. The analysis shows how sticking to the convict code facilitates positioning oneself as knowledgeable within a field of criminality. Perhaps more important, however, is how drawing on the code regulates the relationship to other men and polices one's own behaviour, as well as that of others. Both the trainers and the young men can be seen to use different discourses of masculinity as interactional resources.

    Constructing the Other: Ethnic and Racist Categorizations in Talk on Violence2012In: Social inequality & The Politics of Representation: A Global Landscape / [ed] Celine-Marie Pascale, Thousand Oaks: SAGE , 2012, p. -339Chapter in book (Refereed)
    Abstract [en]

       "In a global landscape the representational practices through which inequalities gain meaning are central--both within and across national boundaries. Social Inequality & The Politics of Representation takes a fresh look at how inequalities of class, race, sexuality, gender and nation are constructed in 20 countries on 5 continents. It offers both rich insight and cultural critique--yet it does not offer a universal paradigm, nor is it concerned with debates about scholarship from "the center" or "the periphery." The collection de-centers North American/European paradigms by placing scholarship from countries around the globe on equal footing. Social Inequality & The Politics of Representation examines timely issues including: Muslim veiling in Austria; poverty among Otomi in Mexico; Indian immigrants in Uganda; race and class in South Africa; Romany rights in Serbia; the (mis)education of Kurdish women in Turkey; collective memory-making in Argentina; internet censorship in China; women's sexuality in Nigeria; orphans in Russia; and transgender cultures in Malaysia. Readers will find a variety of analytical styles including frame analysis, semiotics, poststructural discourse analysis, critical discourse studies, and conversation analysis. Each chapter provides an overview of relevant cultural and historical contexts for an international audience as well as a brief introduction to relevant methodological and theoretical frameworks. Consequently, it is both a richly diverse and easily accessible collection."--Publisher's website.

    Constructing the Other: Ethnic and Racist Categorizations in Talk on Violence2008Article in journal (Other academic)
    Abstract [en]

    Sweden is increasingly becoming multiethnic, resulting in a complex ethnic landscape. The present article documents how two young men in Sweden use ethnic and racist categories in talk about violence, from two distinct but mirroring positions: one explicitly non-Swedish and one a former neo-Nazi. Both young men describe being the target of violence due to being identified as the Other, and both use ethnic and racist categorizations to describe their fighting opponents. It is also argued here that both men are problematizing and deconstructing present and previous identities.

    Abstract [en]

    In this article, a young man's narratives of violence are analysed, and a culturally shared storyline is identified as the basis of these narratives. It is argued that the stories are organized so as to construct a preferred self-presentation. One strategy to achieve this is to establish boundaries for what type of violence to use, whom to fight, where and for what reasons. I also argue that the narratives are structured to avoid being categorized as either victim or perpetrator, although both categories are drawn upon. Issues of masculinity are made relevant through categorization of the characters in the narrative, and positions are made available. Different masculine categories such as the hero/villain/non-man become relevant in the analysis. Different gendered positions are used in negotiating a masculine identity around narratives of and through telling about violence.

    Manlig farlighet. Pedofilen som undandtag2012In: Andra män : maskulinitet, normskapande och jämställdhet / [ed] Lucas Gottzén och Rickard Jonsson, Malmö: Gleerups , 2012, 1, p. -183Chapter in book (Refereed)
    Abstract [sv]

    Sverige är världens mest jämställda land, med världens mest jämställda män. Åtminstone framställs det ofta så, både i offentlig debatt och i vardagliga samtal. Denna bild av den normale svenska mannen upprätthålls dock genom att något annat - eller någon annan - skapas som avvikande, annorlunda, obegriplig eller sjuk.

    I den här antologin diskuteras hur det som uppfattas som goda handlingar används för att representera det gemensamma, medan våldsbrott, kvinnomisshandel och sexism förklaras som ett verk av Andra män. Är det därför som män som misshandlat kvinnor har så svårt att se sig själva som kvinnomisshandlare? Är det därför som fördomsfulla stereotyper av invandrarmän används som förklaring till brott eller sexism?

    Hur kommer det sig i så fall att även feministiska män skapas som avvikande? Och vilka föreställningar utmanas egentligen när äldre män beskriver sina växande bröst som sexuellt laddade och njutbara? Varför kan män med funktionsnedsättning inte debattera hjälp till sex utan att ses som kvinnoförtryckare? Eller varför är pedofilen så närvarande i samtal mellan unga män på ett behandlingshem, medan mäns sexuella våld mot barn är så frånvarande i svenska diskussioner om mäns föräldraskap och män i barnomsorg?

    I Andra män diskuterar forskare från antropologi, genusvetenskap, socialt arbete, sociologi och ungdomsvetenskap hur Andra män pekas ut som avvikande, men också hur dessa män hanterar utpekandet.

    Talking Violence, Constructing Identity: Young Men in Institutional Care2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim of the study is to investigate how young men constructing identities in talk about their own use of violence. The study is based on a fieldwork at a youth detention home in Sweden. The data consists of individual interviews and video recordings of the treatment programme Aggression Replacement Training (ART). Detailed analyses have been made of conversations between the young men, between the young men and the trainers, and of the narratives generated in the individual interviews. The study has a social constructionist approach to identity, which is seen as constructed in a joint achievement in social interaction. An important analytical perspective in the study is how social categories and subcategories are constructed. The study has a particular focus on gender, primarily masculinity, but age and ethnicity are also being emphasised.

    The analysis draws on four empirical studies. It is shown how the young men construct a preferred self-presentation when talking about violent events. The narratives on violence are either based on experiences or talked about as a hypothetical use of violence. Violence based on personal experience is problematized and legitimized in terms of self-defence, defending friends, restraint and justified violence. Narratives of violence are shown to be interactional resources available to the young men. When talking about violence, the young men can be seen to regulate social relations, and to position themselves in relation to particular discourses of masculinity. The specific understanding of what it entails to be a man enables the use of violence with respect to social categorizations such as age, ethnicity or criminal identity. It is also argued that the treatment programme ART may, at times, facilitate maintaining a criminal identity.

    Abstract [en]

    Much of the research, on young men’s violence towards girls is problematised, and linked to sexist attitudes held by young men towards girls. In this article I intend to show that, in discussing violence, violence towards girls is not generally accepted among the young men with a documented history of violence. In a study of violent young men in residential care, undergoing Aggression Replacement Training (ART) the issue becomes pertinent in an ART-discussion. One of the young men discloses that he has hit a girl once. In different accounts he elaborates the motives for doing this, and works to justify his actions. He gives two accounts of the episode in the ART-lesson; in an interview afterwards he produces yet another version. In this article I examine the variations he gives of what happened, how he is striving to position himself as morally justifiable and produce a successful masculine position for himself.

    Barns perspektiv på jämställdhet i skolan: En kunskapsöversikt2010Book (Other academic)
    Abstract [sv]

    Rapporten är en kunskapsöversikt över forskningen om barns perspektiv på jämställdhet i skolan. Den visar att det finns frågor som inte behandlas av forskningen om jämställdhet i skolan. Några exempel på frågorna är barns och ungas upplevelser av hur jämställd skolan är, vilka möjligheter till delaktighet de ges i skolan och hur de anser att skolan är och bör vara organiserad. Kunskapsöversikten har tagits fram av fil dr. Kjerstin Andersson, fil. dr. Ann Nehlin, doktorand Mehek Muftee och doktorand Zulmir Becevic, samtliga verksamma vid Tema barn, Linköpings universitet. Denna rapport ingår som nummer åtta i en serie av forskarrapporter från DEJA.

    Utvärdering av BRIS Internetbaserade stödkontakter2012Report (Other academic)
    Abstract [en]

     

    In  this  evaluation,  children  who  contacted  BRIS via email  or  chat were asked to answer a few questions  concerning  their perceived well- being, the difficulties leading up to the contact, and how they feel they have been treated by BRIS. These questions  were asked immediately before and  after the  contact, as well as 10 days later. In  addition,  a request to participate in a questionnaire study went out to all children who had been active on the BRIS discussion  forums, where they were asked how often they visit the forum, what features they appreciate in the community and how they perceive the help they get in the forum.

    The children  have estimated  their  well-being on a scale from 1  to 9, where  1    represents  "Very  poor"  and  9  "Great".  A  total  of  6,193 children  were asked  to participate  in the  evaluation.  925 responses were submitted during  the period April 1st to June 7th (email & chat) and May 24th  - August 17th (discussion  forum).  The internal  loss is low, 5.05% for the entire  study. Complete  series  in which the child has answered all three questionnaires in the email and chat amounts to only 51,  however, between  220  and  432 questionnaires has  been submitted by the  different  occasions.  A total of 245 questionnaires have been submitted to the evaluation of the discussion  forum.

    The children  report  that their well-being increases  immediately  after the contact with BRIS, regardless  of modality. This however declines in the last follow-up. In general however, they still produce  a higher value than  at the first measurement. The children  reported  that they feel listened  to and that they feel that BRIS is taking them  seriously. The children  who contact BRIS through  discussion  forums  are even more satisfied with the assistance  they receive than the children  who use chat and email. Above all, the discussion  forum helps kids to feel they  are  not  alone  in  their  situation.   The  children   who  use  the discussion  forum  also very much  appreciate  the answers  from other children  and  the  opportunity  to  help  other  children  by answering others postings.

    A small group  of children,  indicate that they feel worse after contac- ting  BRIS. An analysis  of their  answers  describe  either  a dissatis- faction  with  the  provided  advice  or  an  incapacity  to  follow  the provided advice despite them being perceived relevant.

    Statistisk undersökning av näringsämnen i Svartån2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Eutrofiering är ett stort internationellt problem. I Sverige finns de mest näringsrika vattendragen i uppodlade slättbygder i syd- och Mellansverige där lantbruket är en stark bidragande orsak till eutrofiering. Syftet med denna studie var att analysera om övre västra Svartån, som är belägen i sydöstra Sverige, har minskade koncentrationer av fosfor och kväve efter en åtgärdsperiod av tio år. Under åtgärdsperioden har det bland annat slagits vass, muddrats, fiskats ut vitfisk och gett lantbrukare rådgivning angående lantbruksskötsel. Totalfosfor och totalkväve valdes ut att analyseras. Resultat visar att det för totalfosfor är signifikant skillnad efter åtgärdsprogrammets slut vid 33 procent av de analyserade grupperna, där skillnaden är att koncentrationer har minskat. För totalkväve är det sannolikt ingen signifikant skillnad efter åtgärdsprogrammet för någon säsong. Totalkväve-koncentrationer har både ökat och minskat efter åtgärdsprogrammet. En stor orsak till höga koncentrationer av fosfor och kväve i övre västra Svartån är lantbruket, men även punktutsläpp i form av avloppsutsläpp från fritidshus kan vara stor bidragande orsak. Trots att koncentrationer för totalfosfor har minskat, och koncentrationer för totalkväve både ökat och minskat bedöms majoriteten av de analyserade vattendragen som eutrofa vid jämförelse med naturvårdsverkets bedömningsgrunder för miljökvalité både innan åtgärdsprogrammets början och efter åtgärdsprogrammets slut. Vid försök att påvisa effekter av åtgärdsprogrammet är det troligast att Ralången och Säbysjön skulle kunna ha minskade koncentrationer till följd av åtgärdsprogrammet.

    Utarbetning av kriterier för miljömärkning av flygplatser: En studie kring fenomenet Grön flygplats utifrån RPS-modell och teorin om ekologisk modernisering2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Flygbranschen är en global industri som expanderar snabbt och i och med detta ökar också belastningen på miljön genom flygets miljöpåverkan. Ett verktyg som kan användas för att försöka förändra kursen mot en mer hållbar verksamhet är miljömärkning. I Sverige är flygbranschen ett område som det inte existerar några miljömärkningar inom och LFV i Sverige har blivit intresserad av att införa någon typ av miljömärkning av flygplatser.

    Syftet med den här uppsatsen är att utarbeta ett utkast till kriterier för en miljömärkning av Grön flygplats som baseras på flygplatsernas mest betydande miljöaspekter. Studien bygger på RPS-modell, material från enkäter, intervju och dokument. Fenomenet Grön flygplats analyseras sedan med hjälp av teorin om ekologisk modernisering för att få en förståelse för detta fenomen. Ekologisk modernisering kopplar ihop ekonomisk tillväxt och miljöhänsyn, inom denna teori anses vetenskapen och teknologin som viktiga och tillräckliga medel för att lösa och kontrollera miljöproblemen.

    Resultatet av flygplatsernas mest betydande miljöaspekter blev totalt sju stycken. Orsaken till att dessa sju blev de mest betydande miljöaspekterna tolkas som att dessa beror på den centrala plats som en flygplats har med mycket människor i rörelse samt dess geografiska läge. Utefter de betydande miljöaspekterna har kriterierna för Grön flygplats utarbetats vilka totalt blev 17 stycken. Kriterierna skulle kunna överföras på flygplatser inom Norden då flygplatsernas geografiska läge har ett liknande klimat. En flygplats kan dock inte uppnå en hållbar verksamhet enbart på kriterier utan en förståelse måste även fås om att flygbranschen inte kan fortsätta växa som den gör idag. Visionerna om Grön flygplats bygger i likhet med ekologisk modernisering på ekonomisk tillväxt och industriell effektivisering.

    Abstract [en]

    The majority of today's environmental problems are caused by a lack of environmental awareness and behavioral change is essential for reducing human impact. Knowledge of what shapes people's environmental awareness and environmental behavior is therefore necessary.  The aim of this study is to examine children’s environmental awareness and behavior with focus on age and gender. We want to increase the understanding of what affects children’s interest, commitment and understanding of environmental problems and pro-ecological behavior. We have conducted interviews with twenty children in the age groups of nine and twelve years as well as one teacher from each age group. The study highlights the children’s view on the concept of environment, environmental problems, pro-ecological behavior and the future of the environment as well as the children’s interest, commitment and knowledge about the environment. The results show that children’s environmental awareness varies and that there are individual differences which are affected by parents influence and school education. Differences caused by age are observed when it comes to the children’s commitment and interest to the environment as well as their thoughts of the future. Differences caused by gender are not as apparent but is displayed when discussing pro-ecological behavior and the children’s view of the future environment.

    Annual variability of nitrogen concentrations and export from forested catchments: A consequence of climatic variability, sampling strategies or human interference?2000In: Boreal environment research, ISSN 1239-6095, E-ISSN 1797-2469, Vol. 5, no 3, p. 221-233Article in journal (Refereed)
    Abstract [en]

    This study was based on the data from 18 years of monitoring in six forested catchments. The aim was to find links between annual estimates of export and concentrations of NO3-N and organic N and hydroclimatological factors, sampling strategy and human interference. A topography-based wetness index was used to assess whether the effects of forestry activities depended on prevailing wetness conditions. For organic N, annual runoff was the main explaining factor in three catchments. The flow condition during sampling was for organic N the main explaining factor in three and for NO3-N in one catchment. Effects of clear-cutting of 14% in one catchment were observed. For organic N, the model could be improved by considering clear-cutting in wet areas only. The southernmost catchment, but also the northernmost catchment with the lowest deposition, showed links to atmospheric deposition, demonstrating that deposition can cause a significant direct response in streamwater concentrations in nutrient-poor catchments.

    Ecohydrological water flow analysis of a Swedish landscape in a 100 year perspective1989Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The study basically involves analysis in a 100 year perspective of the hydrological response on precipitation from different landscape elements in south-central Sweden, characterized by the interaction of topography, soil type, land management and canopy cover.

    For this purpose, a dynamic water partitioning model, based on the soil moisture balance, was developed together with a Geographical Information System (GIS)-supported method for the detection of the spatial distribution of soil wetness as an indicator of the probability to act as discharge or recharge areas respectively.

    A comparison was made of the performance of water balance models of various complexity. It was shown that, generally, increasing the complexity of the submodels did not improve the agreement with measured soil moisture dynamics. As an example, due to negative feedbacks, the rather conservative nature of transpiration was well described by using 30 years monthly means of potential evapotranspiration. However, two important physical processes that are often neglected in water balance models had to be included: the limitation of transpiration by low soil and air temperatures in spring and early summer, and the drainage of rainwater through unsaturated forest soils.

    The model was used to analyze main differences in hydrological response between forests and open grasslands. It was also used to analyze interannual fluctuations of soil moisture deficts. Ironically, the variability was never as high as in the beginning of the hydrological year. The study revealed considerable fluctuations of 10, 30 and 50-year mean soil moisture deficits, and a general secular trend towards higher summer deficits and larger fluctuations around the median. In the light of the detected critical importance of the choice of time period, the concepts of return and standard periods were challenged. It was shown that the water balance model could be calibrated to simulate also overall basin response. Thus, simulated monthly estimates of both basin evapotranspiration and recharge rates for the Velen Representative Basin agreed well with data determined with other methods.

    The model was also used to simulate the integrated basin response from different parts of the landscape mosaic as determined from GIS-overlays. The obvious advantage of GIS was demonstrated. Finally, changes due to the wetness-impacting human interventions were analyzed. Since the 1870s such activities were shown to, on average, have caused a slight desiccation of the landscape, although the impacts locally could be large.

    Use of participatory scenario modelling as platforms in stakeholder dialogues2008In: Water S.A., ISSN 0378-4738, E-ISSN 1816-7950, Vol. 34, no 4, p. 439-447Article in journal (Refereed)
    Abstract [en]

    A participatory methodology, based on dialogues between stakeholders and experts has been developed and tested in the drainage area to Kaggebo Bay in the Baltic Sea. This study is focused on the EU Water Framework Directive, with emphasis on reduction of eutrophication. The drainage area is included in the WFD administrative area of the Motala Strom River basin. A similar approach is now applied in a recently initiated project in the Thukela River basin, with focus on impacts of climate change on water resources. The methodology is based on the idea that a catchment model serves as a platform for the establishment of a common view of present conditions and the causes behind these conditions. In the following steps, this is followed by model-assisted agreement on environmental goals (i.e. what do we want the future to look like?) and local agreement on a remedy or mitigation plans in order to reduce environmental impact (e. g. eutrophication); alternatively to adapt to conditions that cannot be determined by local actions (e. g. climate change). By involving stakeholder groups in this model-supported stepwise process, it is ensured that all stakeholder groups involved have a high degree of confidence in the presented model results, and thereby enable various actors involved to share a common view, regarding both present conditions, goals and the way to reach these goals. Although this is a process that is time-(and cost-) consuming, it is hypothesised that the use of this methodology is two-pronged: it increases the willingness to carry out remedies or necessary adaptations to a changing environment, and it increases the level of understanding between the various groups and therefore ameliorates the potential for future conflicts. Compared to traditional use of model results in environmental decision-making, the experts role is transformed from a one-way communication of final results to assistance in the various steps of the participatory process.

    Underlag till kontrollstation 2015 för anpassning till ett förändrat klimat2015Report (Other academic)
    Abstract [en]

    As the climate changes, actors on all levels and in all sectors will be affected. Thus it is imperative that authorities, municipalities, businesses and individual property owners all take action.

    Flooding, heat waves, landslides and erosion are only a few examples of the challenges that that society faces and needs to prepare for. Sweden must adapt to the impacts of a changing climate, as well as the indirect effects of climate change impacts in other parts of the world.

    The costs of adaptation can be high, but the European Commission, among others, has deemed that it still pays to adapt in relation to the costs incurred if no action is taken.

    Climate adaptation initiatives in Sweden have advanced significantly in recent years. Notable examples include governmental missions for a national elevation database, landslide risk mapping in the Göta Älv River Valley, the Swedish drinking water investigation, the County Administrative Boards’ regional climate change action plans, and the establishment of the National Knowledge Centre for Climate Adaptation.

    The Swedish Meteorological and Hydrological Institute’s mission to survey, analyse and follow-up on climate adaptation work in Sweden has shown that there is still a considerable need for further measures. This report provides proposals for a road map for climate adaptation in Sweden and concludes that climate adaptation is best conducted in a long-term manner, that roles and responsibilities should be made more transparent, and that better coordination among the many actors involved in climate adaptation is necessary.

    The most important conclusions for continued work are:

    • Laws and regulations need to be adapted; roles and responsibilities as well as strategies and goals should be made clearer.
    • Priority and funding should be given to research and development measures that fill an identified knowledge-gap, including long-term monitoring.
    • Knowledge and decision support as well as prognoses and warning systems should be more accessible.
    • There is a need to outline how the costs of adaptation should be distributed among actors and how resources for prioritised measures can be guaranteed.

    This mission has compiled knowledge of the current and future risks and consequences for society of a changing climate, such as effects on vital societal functions and human health. The mission has also surveyed the work that has been done since the publication of the final report of the Swedish Commission on Climate and Vulnerability in 2007. From this background material our goal has been to describe the gaps and challenges and provide suggestions for how adaptation can be approached in various sectors of society. The EU Strategy on Adaptation to Climate Change has been an important point of departure. The work has been performed in cooperation with national and regional authorities, municipalities, researchers, sectoral organisations and representatives of the private sector.

    This report is comprised of a main report and 18 annexes. Chapter 3 of the main report is a synthesis of all of the proposals made throughout the document and as such can be seen as a road map to ensure that Sweden adapts to a changing climate.

    The Vulnerability Assessment Concept: A Tool for Prioritization of the Most Relevant Issues for Macro-regional Cooperation2013Report (Other academic)
    Abstract [en]

    This report aims at identifying potential issues for collaboration related to climate adaptation through application of a tool for assessing macro-regional risks. The tool is intended to assist decision-makers and other stakeholders in the Baltic Sea Region (BSR) in discussions on how climate adaptation related cooperation would benefit most from macro-regional cooperation. It is based on four criteria: 1) confidence, 2) speed (determined by Baltadapt climate modellers), 3) importance of impacts and 4) macro-regional coverage (based on a questionnaires answered by 3-8 stakeholders from each of the nine riparian BSR states). Based on equal weighting of these factors, impacts related to biodiversity/eutrophication of the Baltic Sea, as well and impacts related to agriculture were given the highest rankings, which demonstrates the importance to include these sectors and their interrelationship as an important focus in macro-regional cooperation on climate adaptation in the BSR. Impacts  related to biodiversity and agriculture have in common that they are caused by climate change that will occur or already has occurred with a high degree of certainty (e.g., linked to air and water temperatures and rising sea levels), as well as having a very large macro-regional spatial coverage, and being perceived as of high societal and/or environmental concern.

    Use of participatory scenario modelling as platforms in stakeholder dialogues2010In: Hydrocomplexity: New Tools for Solving Wicked Water Problems / [ed] Shahbaz Khan, Hubert Savenije, Siegfried Demuth and Pierre Hubert, 2010, p. 187-192Conference paper (Refereed)
    Abstract [en]

     Water-related problems are characterized by complexities, uncertainties and conflicting interests, and there is no single “optimal” way to approach these “wicked” problems. Model-assisted participatory processes have been suggested as one way to meet these challenges. However, the use of models as scenario tools for local planning of mitigation and adaptation strategies addressing environmental challenges is more often an exception than common practice. In order to assess future possibilities for successful use of participatory scenario modelling, experiences from two model-facilitated projects are presented and discussed. The participatory scenario modelling described in this paper implies modelling with people, as opposed to agent-based modelling which is based on modelling people’s behaviour and its consequences. In the first project, a participatory model-assisted process was conducted to formulate a locally proposed remedy plan to reduce nitrogen and phosphorus loads in local lakes and the coastal zone. In the second project, a similar process was used to formulate local adaptation strategies to climate change impacts on water allocation, farming and the environment. Based on the experiences of these projects; recommendations are made as to how model-assisted participatory processes can best be organised and conducted. A key message is that modellers need to rethink their role as “solution providers” to become “process facilitators”.

    Från global klimatforskning till lokal riskanalys och klimatanpassning: Exempel på hur man kan arbeta med lokalt deltagande, kombinerat med modeller i formulering av lokal sårbarhets och anpassningsplaner vid förändrat klimat2010In: Klimatets krav på samhället / [ed] Göran Graninger & Christer Knuthammar, Linköping: Linköping University Electronic Press, 2010, p. 47-64Chapter in book (Other (popular science, discussion, etc.))
    Abstract [sv]

    Sverige hör troligen inte till de regioner i världen som är mest sårbara för klimatvariabilitet och förändringar. Effekter från ett förändrat klimat kommer dock med stor sannolikhet att vara märkbara även lokalt i Sverige, vilket diskuteras mer ingående i Sten Bergströms artikel.

    Denna artikel syftar till att bidra med erfarenheter runt hur man kan arbeta med att ta fram lokalt förankrade anpassningsstrategier. Med tanke på osäkerheter om detaljer i det framtida klimatet, kan det ibland ifrågasättas om det är rimligt att göra stora investeringar på så osäkra grunder. I detta sammanhang är det viktigt att tänka på att anpassningsstrategier för att möta framtida förändringar även gör oss bättre rustade att möta den klimatvariabilitet som vi redan lever med.

    Att välja rätt strategier för framtiden bör därför baseras på identifikation och fokus på de klimatrelaterade problem som vi har redan idag, med fokus på de problem som ger allvarligast effekter för olika sektorer i samhället, samt, baserad på regionalt nedskalade modellberäkningar, identifikation av sannolikheten för att dessa problem kommer att öka i framtiden.

    I denna artikel ges ett exempel på hur man genom aktörsamverkan kan ta fram lokala och regionala åtgärdsplaner. Samverkan har assisterats av klimat och vattenmodellerare, som i dialog med lokala aktörer tagit fram det material som behövts för att föra diskussionerna vidare. Exempel ges från ett pågående projekt i Sydafrika, men metoderna är lika relevanta i Sverige. Liknande metoder har, t.ex. använts för att ta fram en lokalt föreslagen åtgärdsplan mot övergödning i Kaggebofjärden, med medverkan från bl.a. lantbrukare, sommarstugeägare och kommuner (rapport kan beställas från lotta.andersson@smhi.se) .

    Dessutom beskrivs kortfattat ett nystartat INTERREG-projekt, ”Baltic Climate” som bl.a. syftar till att ge kommuner och lokala aktörer runt Östersjön möjlighet att möta klimatförändringarna på ett hållbart sätt..

    Design and test of a model-assisted participatory process for the formulation of a local climate adaptation plan2013In: Climate and Development, ISSN 1756-5529, E-ISSN 1756-5537, Vol. 5, no 3, p. 217-228Article in journal (Refereed)
    Abstract [en]

    This article presents the design and testing of a model-assisted participatory process for the formulation of a local adaptation plan to climate change. The pilot study focused on small-scale and commercial agriculture, water supply, housing, wildlife, livestock and biodiversity in the Thukela River basin, KwaZulu-Natal, South Africa. The methodology was based on stakeholders identifying and ranking the severity of climate-related challenges, and downscaled stakeholder-identified information provided by modellers, with the aim of addressing possible changes of exposure in the future. The methodology enables the integration of model-based information with experience and visions based on local realities. It includes stakeholders own assessments of their vulnerability to prevailing climate variability and the severity, if specified, of climate-related problems that may occur more often in the future. The methodology made it possible to identify the main issues to focus on in the adaptation plan, including barriers to adaptation. We make recommendations for how to design a model-assisted participatory process, emphasizing the need for transparency, to recognize the interests of the stakeholders, good advance planning, local relevance, involvement of local champions, and adaptation of Information material to each groups previous experience and understanding.

    Local assessment of vulnerability to climate change impacts on water resources in the Upper Thukela River Basin, South Africa: Recommendations for Adaptation2009Report (Other academic)
    Abstract [en]

    This report originates from a project entitled Participatory Modelling for Assessment of Local Impacts of Climate Variability and Change on Water Resources (PAMO), financed by the Swedish Development Agency and Research Links cooperation (NRF and the Swedish Research Council).

    The project is based on interactions between stakeholders in the Mhlwazini/Bergville area of the Thukela River basin, climate and water researchers from the University of KwaZulu-Natal (Pietermaritzburg Campus) and the Swedish Meteorological and Hydrological Institute (SMHI) during a series of workshops held in 2007-2009. Between the workshops, the researcher’s compiled locally relevant climate change related information, based on requests from the workshop participants, as a basis for this adaptation plan.

    The aim is to provide a local assessment of vulnerability to climate change impacts on water resources and adaptation strategies. The assessment identifies existing climate-water related problems, current adaptation strategies and recommendations for future action based on likelihoods for change and the severity if such changes will occur.

    Impact of climate change and development scenarios on flow patterns in the Okavango River2006In: Journal of Hydrology, ISSN 0022-1694, E-ISSN 1879-2707, Vol. 331, no 1-2, p. 43-57Article in journal (Refereed)
    Abstract [en]

    This paper lays the foundation for the use of scenario modelling as a tool for integrated water resource management in the Okavango River basin. The Pitman hydrological model is used to assess the impact of various development and climate change scenarios on downstream river flow. The simulated impact on modelled river discharge of increased water use for domestic use, livestock, and informal irrigation (proportional to expected population increase) is very limited. Implementation of all likely potential formal irrigation schemes mentioned in available reports is expected to decrease the annual flow by 2% and the minimum monthly flow by 5%. The maximum possible impact of irrigation on annual average flow is estimated as 8%, with a reduction of minimum monthly flow by 17%. Deforestation of all areas within a 1 km buffer around the rivers is estimated to increase the flow by 6%. However, construction of all potential hydropower reservoirs in the basin may change the monthly mean flow distribution dramatically, although under the assumed operational rules, the impact of the dams is only substantial during wet years. The simulated impacts of climate change are considerable larger that those of the development scenarios (with exception of the high development scenario of hydropower schemes) although the results are sensitive to the choice of GCM and the IPCC SRES greenhouse gas (GHG) emission scenarios. The annual mean water flow predictions for the period 2020-2050 averaged over scenarios from all the four GCMs used in this study are close to the present situation for both the A2 and B2 GHG scenarios. For the 2050-2080 and 2070-2099 periods the all-GCM mean shows a flow decrease of 20% (14%) and 26% (17%), respectively, for the A2 (B2) GHG scenarios. However, the uncertainty in the magnitude of simulated future changes remains high. The simulated effect of climate change on minimum monthly flow is proportionally higher than the impact on the annual mean flow. © 2006 Elsevier B.V. All rights reserved.

    Källsortering, vara eller icke vara?: En fokusgruppstudie kring argument och uppfattningar gällande valet att sortera eller inte sortera.2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    By examine how six different groups in Katrineholm and Malmö talks and arguments about recycling this study aim to identify arguments and perceptions about recycling in the two municipalities. Three focus groups in the age categories 20-26, 30-45 and 46-65 were performed in each municipality. These six focus groups were compared among each other to identify similarities and differences between the age categories and municipalities. Furthermore, previous science and the results from this study were compared in aim to investigate whether this study reflects arguments and perceptions in previous studies or if new arguments were established. The result in this study show that proximity to recycling stations, maintenance of recycling stations, lack of space in the home, knowledge about recycling processes, knowledge about how to recycle, the environmental mentality and positive feedback are, for the participants in this study, working as motivation factors to recycle more. Factors as legislative demands and rate billing were seen as insignificant or in some cases obstacles when increase the participant’s recycling. The results of this study show no differences between the two municipalities, however, differences in arguments and perceptions between the age categories could be interpreted.

    Stormän, bönder och landbor: - jordägoförhållanden i 1500-talets Kalmar län och på Öland2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    I Stormän, bönder och landbor undersöks jordägofördelningen under 1500-talets första hälft i Kalmar län och på Öland. Utifrån kamerala förteckningar från denna tid studeras och beskrivs fördelningen mellan jordnaturerna: skattejord, frälsejord, kronojord, kyrkojord och arv och eget-jord.

    Med detta som utgångspunkt och syfte genomförs uppsatsens undersökning, vilken är tudelad i en kvantitativ och en kvalitativ del. I den första kvantitativa delen undersöks Kalmar län och Ölands härader och socknar beträffande jordägofördelningen under undersökningsperioden. I den andra mer kvalitativa undersökningsdelen presenteras olika förklaringsmodeller till de mönster som framträtt i den första delen.

    Tidigare forskning inom området fungerar som en teoretisk utgångspunkt eller ram för uppsatsen, och då kanske främst för den kvalitativa undersökningsdelen. Resultatet i den kvantitativa, första delen presenteras i 6 olika geografiska områden utifrån de mönster i jordägofördelningen som framträtt. Dessa tolkas därefter med hjälp av de teoretiska utgångspunkterna som inledningsvis redogjorts för. Även lokala faktorer med relevans för sammanhanget vägs in, exempelvis topografi och tidig bebyggelsestruktur i området. Därigenom framkommer uppsatsens kvalitativa resultat i form av ovan nämnda förklaringsmodeller, en för var och ett av de 6 områdena.

    I uppsatsens avslutande del presenteras resultaten från uppsatsen tematiskt utifrån de olika jordnaturerna. Samtidigt ställs uppsatsens resultat i relation med de teoretiska utgångspunkter och den tidigare forskning som finns inom området i en avslutande diskussion. Uppsatsens resultat både bekräftar vissa tidigare formulerade teorier, samtidigt som det motsäger andra teorier. Därför skulle studien kunna fungera som exempel eller på annat sätt styrka eller bestrida den tidigare, men även kommande forskning inom jordägofördelningen under medeltid eller tidigmodern tid.

    Utveckla grundskolans NO-undervisning: Ett elevperspektiv i årskurserna 2, 4 och 9 på undervisningens innehåll2010Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I detta arbete görs en analys av elevers syn på konkret innehåll i naturvetenskap och teknik. Intervjuer med elever har genomförts i fokusgrupper i årskurserna 2, 4 och 9. Syftet var att ta reda på vad elever är intresserade av inom dessa ämnesområden och hur intresset skiljer sig åt i en jämförelse mellan åldrarna. Arbetet ingår i en större studie som regionförbundet Östsam genomför på uppdrag av Skolverket och som har som mål att öka intresset för dessa kunskapsområden i grundskolan. Resultaten indikerar elevers vilja att se helheter, kopplingar till verklighet utanför skolan och att reflektera över samband mellan olika fenomen. Eleverna i samtliga årskurser kan berätta om sina intressen och flera områden är gemensamma för årskurs 2, 4 och 9. Elever i de yngre åldrarna visar större intresse för kataloga aspekter av kunskap medan elever i de senare åren på ett tydligare sätt lyfter fram diskussion, reflektion och kunskapens användning. Resultaten diskuteras i relation till utbildningens syften, frågor om progression och betydelsen av kontakter mellan skola och omgivande samhälle.
