Visby Innerstad : En användningsplan
- 1973
-
Rapport (populärvet., debatt m.m.)abstract
- Sedan lång tid föreligger i stort sett enighet om att bevara innerstadens bebyggelse och att anpassa eventuella nytillskott till det redan bestående. Med den inställningen har förändringsprocessen både dämpats och mildrats men ändå inte bragts att avstanna. Förändringar sker ständigt om det också huvudsakligen i smått: de många synbart så anspråkslösa byggnadsåtgärderna adderar efterhand ihop sig till något större och mer genomgripande. Långsamt, nästan omärkligt, ändrar innerstaden sitt ansikte.Ändå är det inte själva husen som förändrats mest utan användningen av dem. Ur funktionell synpunkt har 1950 - och 60-talen har varit något av en omstörtning i innerstadens historia: den har förlorat nästan hälften av de boende, en stor del av detaljhandeln och praktiskt taget helt sin gamla roll som skolcentrum. I gengäld har ytterstaden vuxit ut till ett sammanhängande kilometerbrett bälte. Till stor del av denna funktionella förändring en följd av beslutet att bevara innerstadens bebyggelse. Vad som inte fått plats inom den gamla ramen har etablerats utandör den.Föreliggande arbete vill ge en översiktlig bild av förändringsförloppen, sedda i ett långt tidsperspektiv men med tonvikt på dagsläget. Bebyggelsen tas upp till utförlig granskning men också användningen av den. Det är just samspelet mellan husen och de funtkioner, de fyller, som kan sägas utgöra bokens huvudtema. I de flesta fall är detta sammanhang hus-användning alldeles konfliktfritt och föranleder därför inte heller någon diskussion. Vad som behandlas är de relativt få problematiska fallen, hus som borde rustas upp för att fylla sin uppgift, hus som är olämpligt nyttjade eller inte använda alls. En serie sådana fall tas upp till systematisk genomgång; samtidigt berörs också de trafik - och miljömässiga konsekvenserna. Bokens syfte är alltså klart: den ger ett underlag av fakta för arbetet med att jämka samman byggnader och användningsformer. I den meningen kan skriften kallas en anvädningsplan för Visby innanför murarna.Arkitekturskolanas arbete har bedrivitis parallellt med den kommunala Innerstadskommitténs verksamhet. Något organiserat samarbete har inte förekommit med de informella kontakterna har varit både täta och goda. Att likheterna mellan Innerstadskommittén och Arkitekturskolans slutsatser blivit så pass stora, kan tillskrivas en gemensam helhetssyn.En av Arkitekturskolans elever, arkitekt Lars-Ingvar Larsson, har tidigare självständigt genomfört en undersökning av förändringar i innerstaden 1945-70- Denna studie publicerats separat och bör uppfattas som ett komplement till den hör föreliggande.Förutom de i innehållsförteckningen nämnda har ytterligare några aktivt medverkat i arbetet. Studiet av trafikfrågorna i innerstaden, i hamnen och öster om ringmuren leddes av Åke Claesson, I fältstudier och diskussioner medverkande Göran Månsson.Arkitekturskolan har fått god hjälp av ett antal initierade personer i Visby. Särskild tacksamhet är vi skyldiga byggnadsnämnden ordförande Henning Jacobson, kommunalrådet C B Stenström, stadsarkitekten Måns Hagbergm f. länsbostadsdorektören Åke Malmberg och landsantikvarien Gunnar Svahnström. I boken publiceringskostnaderna har ekonomiskt bidrag lämnats av Gotlands kommun och Riksantikvarieämbetet.Boken har redigerats av Sture Balgård och Ann Mari Westerlind med hjälp av Henrik O Andersson, Bo Ek, Göran Lindahl, Fredrik von Platen, John Sjöström Gunnar Westerlind och Hans Wetterfors.Skeppsholmen, Stockholm, sommaren 1973.Arkitekturskolans lärare och elever.

Everyday life situations of school-aged children with severe disabilities : what are the goals for the future? an exploratory study
- 2014
-
Ingår i: Journal of Intellectual Disability - Diagnosis and Treatment. - : Lifescience Global. - 2292-2598. ; :2, s. 21-32
-
Tidskriftsartikel (refereegranskat)abstract
- This study investigated present and future everyday life situations (ELS) in home, school, work, and leisure environments for a group of school-aged children with severe disabilities, including complex disorders and a combination of disabilities.The purpose was to explore universal ELS; clarify how the children can be supported in their developmentof autonomy; and to gather information on potential overall goals for interventions. To make data comparable, all reported ELS were linked to the International Classification of Functioning, Disability and Health, Child and Youth version(ICF-CY) and listed along with information on the setting. Both today, and in the future, recreational activities and participation in school or work were of highest importance, but few reported ELS involved directly interacting with otherchildren. More ELS were predicted to occur outside the home and with a higher degree of autonomy. Therefore, interventions would be focused on the overall goal that children with severe disabilities take initiatives to become independent and to form relationships with others.

Fiskbestånd och miljö i hav och sötvatten : Resurs- och miljööversikt 2012
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Detta är den nionde utgåvan av den samlade översikten över fisk- och kräftdjursbeståndens status i våra vatten. Kunskap om fiskbestånden och miljön är en förutsättning för att utnyttjandet av fiskresurserna skall bli bärkraftigt. För svenska vattenområden beskrivs miljöutvecklingen i ett ekosystemsperspektiv, dels för att tydliggöra fiskens ekologiska roll och beskriva yttre miljöfaktorer som påverkar fiskbestånden, dels för att belysa fiskets effekter på miljön.Fiskbestånd och miljö i hav och sötvatten är utarbetad av Sveriges lantbruksuniversitet (SLU), Institutionen för akvatiska resurser (SLU Aqua), på uppdrag av Havs- och vattenmyndigheten. Rapporten sammanfattar utveckling och beståndsstatus för de kommersiellt viktigaste fisk- och kräftdjursarterna i våra vatten. Bedömningar och förvaltningsråd är baserade på Internationella Havsforskningsrådets (ICES) rådgivning, SLU Aquas nationella och regionala provfiskedata, samt yrkesfiskets rapportering.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: Deficits in executive functioning, including working memory (WM) deficits, have been suggested to be important in attention-deficit/hyperactivity disorder (ADHD). During 2002 to 2003, the authors conducted a multicenter, randomized, controlled, double-blind trial to investigate the effect of improving WM by computerized, systematic practice of WM tasks. METHOD: Included in the trial were 53 children with ADHD (9 girls; 15 of 53 inattentive subtype), aged 7 to 12 years, without stimulant medication. The compliance criterion (>20 days of training) was met by 44 subjects, 42 of whom were also evaluated at follow-up 3 months later. Participants were randomly assigned to use either the treatment computer program for training WM or a comparison program. The main outcome measure was the span-board task, a visuospatial WM task that was not part of the training program. RESULTS: For the span-board task, there was a significant treatment effect both post-intervention and at follow-up. In addition, there were significant effects for secondary outcome tasks measuring verbal WM, response inhibition, and complex reasoning. Parent ratings showed significant reduction in symptoms of inattention and hyperactivity/impulsivity, both post-intervention and at follow-up. CONCLUSIONS: This study shows that WM can be improved by training in children with ADHD. This training also improved response inhibition and reasoning and resulted in a reduction of the parent-rated inattentive symptoms of ADHD.

Psychosocial Work Conditions, Health, and Leadership of Managers
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Although psychosocial work conditions, health and leadership are concepts that have been studied for a long time, more knowledge is needed on how they are related in managers. Existing research suggests that managers are very influential in their workplaces, but the way in which their workplaces influence them is often overlooked. As a result, the potential reciprocity between managers’ psychosocial work conditions, health and leadership is not in focus. Furthermore, managers have often been studied as a uniform group and little consideration has been given to potential differences between managers at different managerial levels.The overall aim of this thesis is to increase knowledge about the relationships between managers’ psychosocial work conditions, their health, and their leadership; and to elucidate differences between managers at different managerial levels in these relationships. The thesis consists of four separate papers with specific aims. In Paper I, the aim was to compare the differences in work conditions and burnout at three hierarchical levels: subordinates, first-line managers, and middle managers; and to investigate if the association between work conditions and burnout differs for subordinates, first-line managers, and middle managers. In Paper II, the aim was to advance knowledge of workplace antecedents of transformational leadership, by investigating what psychosocial work conditions of first-line managers are associated with their display of transformational leadership; and whether superiors’ leadership is associated with first-line managers’ display of transformational leadership. In Paper III, the aim was to deepen the understanding of how managers’ health and leadership is related by combining two perspectives in previous research. The two specific research questions were: What psychosocial conditions at work affect managers’ health? How does managers’ health influence their leadership? In Paper IV, the aim was to further the understanding of managers’ perceptions of social support, and to increase our understanding of how managers perceive that receiving social support affects their managerial legitimacy.The empirical material is based on three research projects with quantitative and qualitative designs. Papers I and II are based on cross-sectional data from 4096 employees in nine Swedish organizations. Paper III is based on 42 interviews with managers in a Swedish industrial production company, and Paper IV is based on 62 interviews with managers in a Swedish industrial production company and a Swedish municipality. The interviews were analysed using inductive content analysis.The results showed that psychosocial work conditions and symptoms of burnout generally differed between subordinates and managers, and few differences were found between the managerial levels (Paper I). However, in the associations between psychosocial work conditions and symptoms of burnout, similarities were found between subordinates and first-line managers, while middle managers differed. First-line managers’ psychosocial work conditions were also found to be associated with their display of transformational leadership (Paper II). Psychosocial work conditions were perceived to influence managers’ performance and health, and particularly first-line managers described being dependent on favourable work conditions (Paper III). Furthermore, managers’ health was perceived to influence their leadership, and affect both the quality of their work and the quality of their relationships with subordinates. Managers’ social support came from different people within and outside their workplace (Paper IV). Support that concerned their work came from people within the workplace and was perceived to increase their managerial legitimacy, whereas support that concerned personal and sensitive matters was sought from those outside the workplace so that their managerial legitimacy would not be questioned.The results suggest that managers’ psychosocial work conditions, health and leadership are closely related and can be conceptualized as reciprocal spirals. Some resources in the psychosocial work environment, such as social support, may be hard to take advantage of, even if they are available. The psychosocial work conditions of managers at different managerial levels differ to some extent, which has consequences for how the relationship between psychosocial work conditions, health and leadership is expressed. Especially first-line managers seem to be in a vulnerable position because their influence s more restricted, and they are more dependent on favourable psychosocial work conditions.

Tidskriftsartikel (refereegranskat)abstract
- Several different methods for the extraction, separation, and purification of wood constituents were combined in this work as a unified process with the purpose of achieving a high overall efficiency of material extraction and utilization. This study aimed to present a laboratory-scale demonstrator biorefinery that illustrated how the different wood constituents could be separated from the wood matrix for later use in the production of new bio-based materials and chemicals by combining several approaches. This study builds on several publications and ongoing activities within the Wallenberg Wood Science Center (WWSC) in Sweden on the theme "From wood to material components." Combining the approaches developed in these WWSC projects - including mild steam explosion, membrane and chromatographic separation, enzymatic treatment and leaching, ionic liquid extraction, and fractionation together with Kraft pulping - formed an outline for a complete materials-biorefinery. The process steps involved were tested as integral steps in a linked process. The scale of operations ranged from the kilogram-scale to the gram-scale. The feasibility and efficiency of these process steps in a biorefinery system were assessed, based on the data, beginning with whole wood.

Konferensbidrag (refereegranskat)abstract
- Wood, the most abundant ligno-cellulosic raw material available, is a key potential feedstock for production of more sustainable alternatives to fossil-based materials. However advances within the fields of extraction and treatment processes within what is often referred to as the biorefinery concept is essential to allow for such transition. In this study, several different methods for the extraction and separation of wood constituents have been combined in a single process with the purpose of achieving a high overall efficiency of material extraction and utilisation. The work builds on several activities within the Wallenberg Wood Science Center (WWSC). The aim is to present a laboratory-scale demonstrator that illustrates how the different constituents can be separated from the wood matrix for later use in the production of bio-based materials and chemicals. The process steps involved have been tested as integral steps in a linked process for a scale of operations that range from the kilogram-scale down to the gram-scale. Industrially chipped softwood, containing mainly spruce with some pine, was used as raw material.

Transcript profiling of two potato cultivars during glycoalkaloid-inducing treatments shows differential expression of genes in sterol and glycoalkaloid metabolism

Tidskriftsartikel (refereegranskat)abstract
- Steroidal glycoalkaloids (SGA) are sterol-derived neurotoxic defence substances present in several members of the Solanaceae. In the potato (Solanum tuberosum), high SGA levels may render tubers harmful for consumption. Tuber SGA levels depend on genetic factors, and can increase as a response to certain stresses and environmental conditions. To identify genes underlying the cultivar variation in tuber SGA levels, we investigated two potato cultivars differing in their SGA accumulation during wounding or light exposure; two known SGA-inducing treatments. Using microarray analysis coupled to sterol and SGA quantifications, we identified a small number of differentially expressed genes that were associated with increased SGA levels. Two of these genes, encoding distinct types of sterol Delta(24)-reductases, were by sense/antisense expression in transgenic potato plants shown to have differing roles in sterol and SGA metabolism. The results show that an increased SGA level in potato tubers during both wounding and light exposure is mediated by coordinated expression of a set of key genes in isoprenoid and steroid metabolism, and suggest that differences in this expression underlie cultivar variations in SGA levels. These results may find use within potato breeding and quality assessment.
