Reports (other academic/artistic)abstract
- Socialhögskolans årsbok ger en liten inblick i vad vi gör och vi hoppas att den bidrar till att presentera utsnitt från vår verksamhet på ett trevligt och samlat sätt. Årsboken som är Socialhögskolans tredje uppmärksammar inte bara det som skett på Socialhögskolan under 2018. Den uppmärksammar även att 2018 var året då svensk äldreomsorg fyllde 100 år. Årsbokens gästredaktör Per Gunnar Edebalk inleder därför bokens forskningsavsnitt med att i år skriva om just hundraåringens historia. Det är inledningen på ett avsnitt där flera forskare vid Socialhögskolan bjuder på bidrag som lyfter fram aspekter av äldreomsorg och åldrande.Håkan Jönson och Tove Harnett resonerar om de begrepp som omgärdar äldreomsorgens möten och organisering sett i ett socialt arbetets perspektiv. De två har även skrivit en artikel om huruvida behov ska ses annorlunda mellan grupper bara för att man passerat en viss ålder.Däremellan presenteras en text av Erika Werner som låter oss möta frågor kring en sviken generation, här genom ett möte med Agnes, som hamnade mitt i skarven när pensionssystemet reformerades. Elisabeth Carlstedt presenterar en text om hur äldreomsorgens särskilda boenden arbetar i relation till Socialtjänstlagens direktiv om meningsfullhet och värdighet, och hur svårt det är. Lars Harrysson presenterar därefter ett avsnitt om två forskningsprojekt som han och Erika Werner gjort där fokus har legat dels på pensioner för personer i ekonomiskt utsatta grupper, speciellt med migrantbakgrund, dels om hur tro och äldreomsorg samspelar, eller inte. Äldreomsorgsavsnittet avslutas sedan med en intervju som Patrik Hekkala gjort med Peter Andersson som startade kursen socialt arbete med äldre och med Tove Harnett som tagit över och fortsatt utvecklingsarbetet till dags datum.Årsboken avslutas sedan med fyra texter. En av Amina Abboud, snart färdig socionom, som skriver om sina erfarenheter av och i uppsatsskrivandet. Sedan en där vi får möta Carina Olsson som arbetat hos oss länge, men som faktiskt arbetat vid universitetet i 40 år 2018. Emelie Dahlström, Joakim Grina och Jan Abrahamsson ger sedan en bakgrundsteckning till en hos Socialhögskolan verksam social accelerator, SoPact. Som avrundning finner du sedan lite mer information om vår verksamhet här vid Socialhögskolan.

Differential expression of human endogenous retroviral sequences similar to mouse mammary tumor virus in normal peripheral blood mononuclear cells
- 1996

In: AIDS Research and Human Retroviruses. - 0889-2229 .- 1931-8405. ; 12:9, s. 833-40

Journal article (peer-reviewed)abstract
- Mouse mammary tumor virus (MMTV) is a retrovirus that causes breast cancer in certain strains of mice. In a previous study we identified, by sequencing clones from human lymphocytes, six groups with similarities to MMTV. Using a primer pair derived from pol sequences conserved within types A, B, and D retroviruses and probes from the six human MMTV-like (HML-1 to HML-6) groups in an internally controlled hybridization assay we investigated the normal variation of expression in PBMCs. Variations occurred within all groups but was most significant within group HML-1, where hybridization signals differed by more than 500-fold between individuals. Groups HML-2 and HML-3 showed consistently stronger hybridization signals than groups HML-1 and HML-5, while group HML-6 resulted in weak signals for all individuals. Stringent hybridization of the amplified cDNA to 20 individual HML clones also demonstrated a marked heterogeneity of expression. Hybridization signals from some groups and sequences were found to be correlated, either in a positive or negative fashion. RNA isolated from PBMCs collected from two donors at four different time points (in the morning and in the afternoon on the same day, repeated 1 week later) was also analyzed using the six hml probes. A small variation in hybridization signals was seen in samples collected on the same day, but a larger difference was observed in samples taken 1 week later. The correlations and the differences in the expression of HMLs between individuals implicate a complex transcriptional regulation system of these sequences.

Factor demand flexibility in the primary aluminium industry : Evidence from stagnating and expanding regions
- 2011

In: Resources policy. - : Elsevier BV. - 0301-4207 .- 1873-7641. ; 36:3, s. 238-248

Journal article (peer-reviewed)abstract
- The purpose of the paper is to analyse and compare short-run factor demand responses to price changes in the primary aluminium industry in Western Europe and the Africa-Middle East (AME) region. We outline a Translog variable cost function model, which is estimated employing a panel data set at the individual smelter level over the time period 1990-2003. The empirical results show evidence of limited - but far from insignificant - price-induced factor demand responses in the short-run. Overall aluminium smelters in the AME-region show evidence of higher estimated short-run own- and cross-price elasticities than their competitors in Western Europe, at least when it comes to labour and electricity demand. One important reason for this result is the greater number of pot lines with slightly different technologies at each smelter as well as the more intense use of the Prebake technology in the AME-region making retrofits in existing plants less costly than in Western Europe. The results also suggest that in both regions the demand for electricity has over time become less sensitive to short-run price changes, while the labour and material demand responses to price changes have increased but only in the AME-region. The liberalisation of the Western European electricity markets in combination with the rigid labour markets in this part of the world suggest that the shift in production capacity from the western world to the AME-region as well as China may continue

The economics of secondary aluminium supply: An econometric analysis based on European data
- 2009

In: Resources, Conservation and Recycling. - : Elsevier BV. - 0921-3449 .- 1879-0658. ; 58:8, s. 455-463

Journal article (peer-reviewed)abstract
- The purpose of this paper is to analyze the economics of secondary aluminium supply in Western Europe. We derive a supply model of secondary aluminium recovery and recycling, which integrates microeconomic theory of production with a dynamic model of scrap generation and accumulation. The supply function contains the secondary output price, a vector of input prices, and a measure of the size of the stock of old aluminium scrap. The model is estimated using pooled cross-section and annual time-series data for four European countries, Germany, France, Italy and the United Kingdom, over the time period 1983-2000. The estimated own-price elasticity of secondary aluminium supply is low (0.21) as is the supply response to changes in the stock of old scrap. The empirical results are useful for analyzing market behavior and policy impacts in the secondary aluminium market. The low supply responses to changes in the output price can - in combination with the high-income elasticity of material demand - help explain the observed price volatility of secondary aluminium prices. They also suggest that price-based policies influencing the supply side of the market may only have limited impacts on aluminium recycling rates, and that national collection of aluminium scrap is likely to have small influences on secondary aluminium production internationally.

Non-target Effects of Genetically Modified Trees
- 2007
-
Doctoral thesis (other academic/artistic)abstract
- To date, few studies have focused on the effects of genetically modified trees (GM trees) on the environment. One concern with GM trees is that they may have unanticipated effects on non-target organisms, i.e. effects on organisms that are not direct targets of the genetically modified trait. The main objective of this thesis was to study potential non-target effects from the interaction between GM trees and natural enemies, including phytopathogens and herbivorous insects. To study this I used a system consisting of GM trees featuring changes in growth-related characteristics, and naturally occurring enemies. The GM trees used were the aspen hybrids Populus tremula x tremuloides: one unmodified wild type clone T89 (control) and transgenic lines with altered expression of gibberellin (GA 20-oxidase), sucrose (SPS) or pectin (PME); and Populus tremula x alba: one unmodified wild type clone INRA 717-1-B4 (control) and lines modified to suppress the activity of the enzymes in the lignin biosynthetic pathway, i.e. CAD, COMT, CCR or CCoAOMT. The natural enemies used were the parasitic phytopathogens Melampsora pinitorqua, M. populnea and Venturia tremulae, and the herbivorous leaf-beetle Phratora vitellinae. To address this question inoculation experiments, feeding preference experiments, analyses of secondary chemistry and field inventories were performed. The results of the studies showed that the GM trees significantly affected the interaction with the natural enemies, both in the laboratory as well as in the field. For instance, both M. pinitorqua and V. tremulae showed an altered disease incidence on the GM trees of P. tremula x tremuloides compared to the unmodified wild type T89, where all tested transgenic lines exhibited altered susceptibility to the pathogens. However, there were also differences in aggressiveness to the aspens depending on pathogen population. The results from the field inventory showed that lines within all tested transgenic construct, COMT, CAD, CCoAOMT and CCR of P. tremula x alba differed significantly from the wild type INRA 717-1-B4 in susceptibility to M. populnea. In addition, the susceptibility to the rust also differed significantly between lines carrying the same transgenic constructs. Furthermore, we found that overexpression of SPS in P. tremula x tremuloides, unintentionally induced changes in plant secondary chemistry, where the GM-line SPS33A exhibited the largest deviation from the wild type T89 in contents of plant phenolics and nitrogen, and that these changes coincide with a concurrent decrease in herbivory by P. vitellinae on this line. I argue that the altered interactions are the result of physiological changes in the trees. They can originate from direct effects i.e. altered expression of the modified trait, indirect effects of the genetic modification process e.g. pleiotropy, or effects from the transformation process e.g. position effects, to which the tested natural enemies respond. The result stresses the importance of further research on the causes and mechanisms responsible for the altered interaction between GM trees and non-target organisms, as well as evaluating the potential environmental effects of cultivation of GM trees in the field. Such research will require collaboration between researchers from different disciplines, such as plant ecology and physiology, functional genomics, proteomics and metabolomics.
