Risken finns - men hur avgör vi vad den betyder?

Huruvida mänskligt beslutsfattande och riskbeteende är att betrakta somirrationellt eller rationellt beror på vilken teoretisk utgångspunkt som antas. Enligt ?expected utility?-teori och ?prospect?-teori uppfattas dessa som irrationella då det visar sig att användandet av olika heuristiker eller tumregler leder till systematiska felbeslut och teoretiska överträdelser. Utifrån ett evolutionärt perspektiv ses dock dessa överträdelser inte alls som systematiskt felaktiga utan betraktas istället som ekologiskt rationella enligt ?bounded risk distribution? modellen.

Sömn, depressionssymtom, livskvalitet och Alzheimers sjukdom

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

Utvärdering av konsekvenserna för nätanslutning av vindkraftparker i Sverige vid införandet av nätkoden Requirements for Generators

Grid codes are becoming more demanding on power generating units due to the factthat the complexity of the power grid is increasing. The penetration of wind powerhas grown over the last years and it is clear that wind farms need to be addressedwith the same type of grid codes as conventional generation units. There is howeveran undeniable difference between the technology in conventional synchronousgeneration units, and the asynchronous generation units in wind farms.This thesis has reviewed the current grid code in Sweden and compared it to the newcode proposed by ENTSO-E, ?the Requirements for Generators?, in the aspect ofwind farms with an installed power of 30 MW or more. The comparison has beencomplemented by an analysis of how wind farms of two different technologies(Doubly fed induction generators and full power converters) can meet therequirements and technical proposals have been given on how to be able to meetcompliance with the new grid codes.The Requirements for Generators contains many non-exhaustive and optionalrequirements, because of this it has been difficult to, at this stage, exactly point outthe technical impact on the grid connection of future wind farms in Sweden.

Kartläggning av nätförlusternas storlek inom Mälarenergis elnät

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

Förbättringsförslag till inrikes vägtransporter hos Draka Kabel Sverige AB

Logistik handlar om att skapa effektiva materialflöden. Distribution är den del av logistikflödet som har stor betydelse för företags konkurrensförmåga och lönsamhet. Hur företag väljer att distribueras sina tjänster eller produkter har en stor påverkan på deras transportkostnader och leveransservice. Hos Draka Kabel Sverige AB finns i nuläget ingen uttalad leveransstrategi gällande uppbokning av inrikestransporter, utan detta sker efter kundönskemål. Detta leder till många små leveranser som resulterar i högre transportkostnader och ostrukturerade arbetsrutiner. I dagsläget samarbetar Draka Kabel Sverige AB med en speditör, Höglands Logistik AB, och all inrikes vägtransport sker med speditören.

Jämkning av skadestånd och ansvarsförsäkringar

Damages have four main functions: reparation, placing of the costs, distribution of the losses and prevention. The rules about damages evolved before liability insurance had the extension it has today, 97 % of the Swedish populations is covered by liability insurance, since it is included in the comprehensive household insurance. Liability insurance should be looked at in the light of the damage rules, but the rules about damages are adapted to the insurance possibilities.The Law of damages contains, though the general adjustment article 6:2, the adjustment article 2:4 about children and the adjustment article 2:5 about the mentally ill, a possibility to adjust a non reasonable damage claim. If the liability insurance covers the damages no adjustment is made. Even when the adjustment articles are being used the damages is a heavy burden for the person who is liable for the damages.

Hur påverkar en ökad andel solceller Umeå Energis elnät? : ? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

Effekter av fysisk aktivitet på psykisk ohälsa hos unga kvinnor

Among young adults and especially women, psychological issues are common phenomena in the society such as depression, anxiety and stress. Research has shown that physical activity can be a complement for anti-depressant medication. The aim of this review is to examine previous research to find out how physical activity can provide positive effects on overall mood state in particular young women's psychological health. The results of this review is that there are support in the literature of young women that physical activity may enhance mood in studies of depression and anxiety symptoms and small support for the effects on reducing stress. Physical activity with both high intensity and low intensity has shown to have positive effects on depression and anxiety, but the physical activity has to be regular for long-term effects.

Skapandet av ett fredligt samhälle. Vad kan vi göra? : En studie av gymnasieelevers uppfattning om skolans och deras egen roll i skapandet av en fredligare värld

The aim of the study is to examine what upper secondary school students think that they themselves and their school can do to create a peaceful society. The study combine qualitative and quantitative methods based on questionnaires distributed among 328 students in three high schools in Sweden. The survey is a combination of multiple choice and open questions. For the analysis of quantitative responses the computer program SPSS was used producing frequency tables and response rate schemes. To analyze the questionnaire's qualitative part a narrative analysis method was used.

Metoder för att undersöka effekterna av naturvårdshänsynen i skogsbruket efter den nya skogsvårdslagen

In 1994 a new Forestry Act was accepted in Sweden. One of its aims was to raise the consideration for preservation of biodiversity. Since this happened over 15 years ago there is now an interest in analyzing if the law has been effective in its purpose. In this study methods suitable for analysis are being investigated. The study contents a pilot study of methods for five parameters that can validate if the law has been followed.

Riskbaserat provtagningsprogram för mikroorganismer i Gäddviks vattentäkt

Risk-based sampling program of microorganisms in the water source in northern SwedenAfter several disease outbreaks caused by parasites in the drinking water during the last years, it is more essential than ever to insure that the water supply companies have enough barriers to counteract the presence of microorganisms in the outgoing water. It is also discussed whether climate changes such as increased precipitation can have a connection to the increased cases of parasites in water sources. The water source at Gäddvik is Luleå municipality?s largest and provides drinking water to 64 500 of Luleå?s 74 000 inhabitants. The investigation of microorganisms in the water source, especially in the Lule River has not been as prioritized as the sampling of chemical parameters.

Jämlika förutsättningar för kvinnor och män: En enkätstudie av jämställdhetsarbetet i den regionala biblioteksverksamheten

This masters thesis investigates how the Swedish county libraries relate to equality between men and women. The thesis treats the county library both as a place of work and as a part of the national library network. One of the reasons why this study focuses on county libraries is because of their special position in the Swedish library organisation as a link between the national policy and the public libraries. The analysis in the study is based on theories that argue masculinity and femininity as social constructions, and therefore can be affected by a different type of conduct. Data was gathered using qualitative questionnaires combined with some quantitative elements that were used to gain fundamental facts regarding the distribution of employees between the sexes and the existence of equality policies.

Estimation of reindeer lichen biomass by image analysis

During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.

Kön, politik och makt - Den diskursiva kampen om tolkningsföreträde: empiriskt exempel Feministiskt initiativ

This essay is a discourse and a feminist theoretical analysis that focuses on the alternative discourse that we consider Feminist Initiative to be constitutive of. Our theoretical stance, with base in Laclau and Mouffes discourse theory, builds on the notion that reality is characterised by conflicts between different competing discursive formations and that the social is an endless struggle over the preferential right of interpretation of meaning. More specifically, the essay focuses on the discursive struggle over the meaning of the term politics. It is our understanding that the dominant perception of politics necessarily excludes other understandings, which can according to Eduards, be explained as a consequence of a patriarchal distribution of power that renders the subordination of certain understandings of politics accordingly. Feminist Initiative, as an alternative discourse, can therefore be perceived as a threat to the dominating discourse of politics, which in order to maintain its preferential right of interpretation seek to illegitimatise and depoliticise the politics that the alternative discourse represents.

Grammatisk finithet i trumaí

Traditionellt har tempusböjning och person-/numeruskongruens på verb varit de starkaste kriterierna för finithet. Det har dock visat sig vara svårapplicerade kriterier för många språk och finithet på satsnivå ? huruvida en sats är självständig eller ej ? har blivit en viktig fråga för definitionen.Uppsatsen syftar till att beskriva och analysera finithetsfenomenet utifrån språket trumaí.Det tycks finnas flera fenomen som är tecken på en finithetsdistinktion i trumaí, framför allt -n/-e-klitikan som markerar 3Abs på verbet vid absolutivargumentets frånvaro, samt FT-partiklarna som har en tempusfunktion. För imperativ verkar det vara så att imperativpartiklarna har en intern distribution baserad på person och animathet hos absolutivargumentet, vilket kan tolkas som att det finns en argumentkongruens frikopplad från den semantiska inkorporeringen av andraperson som subjekt. Gällande finithet på satsnivå finns det i trumaí både finita och infinita satser som kan fungera som bisatser.
