1800-talets mediesystem
- 2010
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Mediehistoria skrivs ofta utifrån ett medium i taget. Den här boken argumenterar istället för att historiens medier utvecklats tillsammans.Nya former, tekniker och praktiker har interagerat med gamla, innehåll har cirkulerat medierna emellan och rader av aktörer har aktivt relaterat till en helhet av uttrycksformer. Denna helhet var konturfast på ett vis som gör det befogat att tala om ett historiskt mediesystem: summan av en viss tids medier och deras inbäddning i sociala, politiska och ekonomiska villkor. I ett antal delstudier prövar boken möjligheterna att på närgången empirisk nivå undersöka 1800-talets mediesystem.

Case-based reasoning for assessment and diagnosis of depression in palliative care
- 2010
-
Ingår i: Proceedings - IEEE Symposium on Computer-Based Medical Systems. ; , s. 480-485
-
Konferensbidrag (refereegranskat)abstract
- The goal of the research presented is to create a computational framework and system architecture for clinical decision support in palliative care. The application focused is the classification of depression. The method under investigation is case-based reasoning, motivated by the complexity of the domain and a lack of generalized principles of sufficient coverage and strength for diagnosis and treatment. A system architecture is described and exemplified through an implemented prototype. The outcome of the research so far is a system that captures the properties intended, and for which a clinical test set-up has been defined. © 2010 IEEE.

Dödsfall under och efter skuldsanering
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Konsumentverket har enligt skuldsaneringslagen (SFS 2006:548) uppdrag att stödja och vägleda den budget- och skuldrådgivning som kommunerna skall svara för. Detta innefattar bland annat utbildning, metodutveckling, kunskapsbyggande och information samt utvärdering. Som ett led i detta har verket initierat en utvärdering av verksamheten från, såväl ett gäldenärsperspektiv som ur ett samhällsekonomiskt perspektiv. Föreliggande rapport är en del av en kommande större rapport rörande bl.a. ekonomi och hälsoaspekter i samband med överskuldsättning och skuldrådgivning i kommunerna. Författare är docent Richard Ahlstöm och forskningsassistent Mattias Savemark. De slutsatser och ståndpunkter som redovisas här är författarnas egna och de ansvarar för delrapportens riktighet och innehåll.

The rolling resistances of roller skis and their effects on human performance during treadmill roller skiing
- 2010
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Modern ski-treadmills allow cross-country skiers, biathletes and ski-orienteers to test their physical performance in a laboratory environment using classical and freestyle techniques on roller skis. For elite athletes the differences in performance between test occasions are quite small, thus emphasising the importance of knowing the roller skis’ rolling resistance coefficient, µR, in order to allow correct comparisons between the results, as well as providing the opportunity to study work economy between different athletes, test occasions and core techniques.Thus, one of the aims of this thesis was to evaluate how roller skis’ µR is related to warm-up, mass, velocity and inclination of the treadmill. It was also necessary to investigate the methodological variability of the rolling resistance measurement system, RRMS, specially produced for the experiments, with a reproducibility study in order to indicate the validity and reliability of the results.The aim was also to study physiological responses to different µR during roller skiing with freestyle and classical roller skis and techniques on the treadmill as a case in which all measurements were carried out in stationary and comparable conditions.Finally, the aim was also to investigate the work economy of amateurs and female and male junior and senior cross-country skiers during treadmill roller skiing, i.e. as a function of skill, age and gender, including whether differences in body mass causes significant differences in external power per kg due to differences in the roller skis’ µR.The experiments showed that during a warm-up period of 30 minutes, µR decreased to about 60-65% and 70-75% of its initial value for freestyle and classical roller skis respectively. For another 30 minutes of rolling no significant change was found. Simultaneous measurements of roller ski temperature and mR showed that stabilized mR corresponds to a certain running temperature for a given normal force on the roller ski. The study of the influence on mR of normal force, velocity and inclination produced a significant influence of normal force on mR, while different velocities and inclinations of the treadmill only resulted in small changes in mR. The reproducibility study of the RRMS showed no significant differences between paired measurements with either classical or the freestyle roller skis.The study of the effects on physiological variables of ~50% change in µR,showed that during submaximal steady state exercise, external power, oxygen uptake, heart rate and blood lactate were significantly changed, while there were non significant or only small changes to cycle rate, cycle length and ratings of perceived exertion. Incremental maximal tests showed that time to exhaustion was significantly changed and this occurred without a significantly changed maximal power, maximal oxygen uptake, maximal heart rate and blood lactate, and that the influence on ratings of perceived exertion was non significant or small.The final part of the thesis, which focused on work economy, found no significant difference between the four groups of elite competitors, i.e. between the two genders and between the junior and senior elite athletes. It was only the male amateurs who significantly differed among the five studied groups. The study also showed that the external power per kg was significantly different between the two genders due to differences in body mass and mR, i.e. the lighter female testing groups were roller skiing with a relatively heavier rolling resistance coefficient compared to the heavier testing groups of male participants.

SMALL SCALE IN-SITU BIOREMEDIATIONOF DIESEL CONTAMINATED SOIL –SCREENING LIFE CYCLE ASSESSMENT OF ENVIRONMENTAL PERFORMANCE

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Spillage of diesel oil and other petroleum products is a commonly creating need for siteremediation of contaminated soils. In Sweden the most common remediation action isexcavation of the contaminated soil and off site biological treatment by composting.However, a number of small sites spread out in rural areas end up low on priority lists, andwill not be attended to within foreseeable future if ever. For such areas a low cost, easy toapply remediation techniques would be of interest. Enhanced bioremediation of dieselcontaminants in soil by whey addition has been demonstrated in lab scale. Whey is a byproductfrom cheese production. A first pilot remediation trial on an actual site in Gäddede,County of Jämtland, was started the summer of 2010. Using this site as a case study ascreening life cycle assessment model has been set up. The goal of the study was toinvestigate the environmental performance of the whey method, to benchmark the wheymethod toward the excavation and composting practice and to identify environmental hotspots in the whey treatment life cycle. The study aims at establishing if further work shouldbe put into developing the method, or if the environmental performance is such that the wheymethod should be abandoned. It should be noted that even with a slightly worseenvironmental performance compared to other remediation alternatives whey treatment couldstill be of interest, since the small scale sites in rural areas we talk about here otherwise mostoften would not be attended to.Results from the screening life cycle assessment indicate a rather good environmentalperformance of the whey method, partly depending on impact category considered. For thewhey method, impacts from farming activities in the milk production chain allocated to thewhey give significant contributions. Transportation gives important impacts from both thewhey method and the excavation and off site composting, thus logistics should always beconsidered and optimized. The whey on-site treatment could be an interesting alternative forbioremediation especially at sites that would not otherwise be treated, due to small size orremote location.
