Kartläggning av snökanoner över Östersjön
Convective snowbands is a weather phenomenon that is associated with heavy snowfall in a limited area. They are formed over ice-free parts of e.g. the Baltic Sea when there is a cold easterly airflow over relatively warm water. These convective snowbands can cause large amounts of snow along the Swedish east coast, often causing traffic hazards. Sometimes they can even paralyze an entire community. In this study, convective snowbands that have formed over the Baltic Sea during the period 1980-2009 are examined, in order to find out how often they occur, what place they are most common and in what month they usually appear.
Mälarens vattennivå i ett framtida klimat
The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.
Enhetschefens upplevelse av hälsofrämjande ledarskap - En kvalitativ studie inom primärvården/Landstinget i Mellansverige.
Trycksår orsakar lidande för patienter och höga kostnader för sjukvården. För att förhindra uppkomst av trycksår är det viktigt att identifiera patienter med ökad risk för trycksår samt att aktivt arbeta med preventiva omvårdnadsåtgärder. Ett strukturerat arbetssätt kan göras utifrån kvalitetsregistret Senior Alerts rekommendationer. Senior Alert är inriktat på förebyggande vård av äldre över 65 år och i registret registreras bland annat risk för trycksår, planerade åtgärder samt sjuksköterskans utvärdering av de insatta åtgärderna. Syftet med studien var att kartlägga täckningsgrad, utförda riskbedömningar och planerade åtgärder avseende risk för trycksår i kvalitetsregistret Senior Alert.
Märstaån ? ett vattenlandskap : Är våtmarker och dammar vägen framåt?
The overall aim is to examine how the European Union Water Framework Directive has affected the local water management in the catchment Märstaån situated in the eastern part of the lake Mälaren river basin, Sweden. The first part of the study gives an historical overview of the area with focus on how the old agricultural landscape was handling the nutrient load from farming activities by means of different kinds of wetlands. By using the concept of the procedural landscape, introduced by Torsten Hägerstrand , together with historical maps with dates starting from the 17th century, the pre-modern landscape is analyzed. The second part is an investigation, based on qualitative data, on how the different actors in the catchment area work together to secure the water quality for the Märstaån river. The analysis shows that the Märstaån catchment river systems are mostly unchanged in the rural areas. The exception is the mainstream section of the Märstaån river running partly underground today and the Halmsjöbäcken river that is heavily affected by the Arlanda airport situated within the catchment area.
Tillsats av biokol till en svensk sandjord : effekter på lustgasavgång, kväveretention och andel vattenfyllda porer
In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.
Betavärdet som mått på systematisk risk inom aktievärdering
The beta value is frequently described in theory and is a well known factor to quantify the systematic risk in shares through the CAPM model. Initially, this study describes the advantages and difficulties with the estimating process and the problematic nature of the assumptions and descisons included in published beta values.An alternative method, Bottom-up beta, to estimate the beta value that probably has not been tested under Swedish circumstances is applied. The problems and decisions that have to be made to derive an alternative value are studied in detail through six separate steps. I have chosen nine companies at the Stockholm Stock Exchange where this method is used. The result showed that the systematic risk were higher at five shares and lower at four, compared to the published values.Finally there is a discussion about the practise, usefulness and opinions concerning how to estimate and interpret the beta value to determine the expected return..
Tätortsnära skogsbruksplan i Borås stad
This report is part of an Bachelor of Science work in forestry, conducted for the community of Borås, Sweden. In order to create a forest management plan for the area of Hestra, a survey was conducted. People living in the area were given the opportunity to reply to the survey. The questions in the survey are both personal and forestry-related. The aim is to reach out to the different categories of people when it comes to age, living and the different aspects of visiting the woods.
Projektorganisationens hantering av risker och osäkerheter ? Fallstudie av ett promotionprojekt inom musikbranschen
Syfte: Projektet, som vi studerat, har genomförts i en bransch, där uppfattningen råder att osäkerheten i omgivningen är stor och att risker ses som ett frekvent inslag. Syftet med denna studie är att utforska huruvida ett projekt under dessa premisser tvingar fram ett systematiskt användande av Project Risk Management eller om man använder sig av en annorlunda strategi för att hantera risk- och osäkerheter. Vår avsikt är även att se till de orsaker som ligger bakom handlandet och hur projektgruppens arbetssätt har fungerat. Metod: Vi har utgått från det hermeneutiska synsättet, där vi genom kvalitativa intervjuer tagit del av ett promotionprojekt vid en artistlansering. Promotionprojektet avser ett debutband på ett independentskivbolag.
Myt och vetenskap om kastration av tik
This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.
Vad händer med åsikterna? : Järvadialogen som kommunikationsinsats
The area of Järvafältet in the northern parts of Stockholm is one of the many large-scale investments into Swedish residency executed in the 60?s and 70?s, and which got the name Miljonprogrammet. Not until today these buildings have been restored, and frustration has been brewing in these areas for some time. Järvadialogen is the name of a communication program connected to the housing restoration in the area of Husby, which is a part of Järvafältet, and functions as a promotional and informational dialogue between residents in the area and those responsible for the communication program. The cultural diversity in the area of Husby is significant, and with theories on intercultural communication, change communication and power we study the performed communicative process and the manner in which it is received.
STABILITET I INSOMNI, ÅNGEST, DEPRESSION OCH UTBRÄNDHET OCH RELATIONERNA TILLSTÅNDEN EMELLAN
Mental illness is today the leading cause of long-term sick leave and insomnia, anxiety, depression and burnout are among the most common conditions. The aim of the study was to investigate the stability of these conditions and how this is influenced by gender and age, as well as the extent to which these states are risk factors for each other. The participants were a random sample (n = 2336) from the general population in the age of 18-79 years. The results showed that stable illness was more common among women than men, and that stable illness decreased with aging. The stability itself was not affected by gender or age. Relations between the conditions were bidirectional and they constitute major risk factors for each other (odds ratios, OK = 2.37 to 6.46). The largest risk factor for a condition is, however, previous occurrence of the same problem. Previous burnout was found to be a significantly larger risk factor for future burnout than previous insomnia for future insomnia (OK = 9.63 and 5.74, respectively). The results suggest that insomnia, anxiety, depression and burnout, despite their differences, are similar regarding symptoms and underlying causes. The importance of early interventions to prevent comorbid conditions which are more complicated and more difficult to treat is emphasized..
Skogsskötsel för att främja sociala och estetiska värden i ett friluftsområde i Trollhättans Stad
Over 80% of Sweden's population lives in urban areas, and half of the country's forest visits will thus be in urban woodlands. Social values ??- how the individual experiences the forest, and the impact of the forest visits on individual health and well-being, are pointing to the importance of managing the urban woodlands.When there comes to the cultivation of the urban woodlands there are usually many opinions to consider.This study aims to investigate the various opinions on the use and forestry in an urban recreation area in ??the City of Trollhättan. The study addresses both general and in four cases specific suggestions on management methods.Data was obtained from both quantitative and qualitative study through survey, interviews and discussions with the users of the recreation area.Trollhättan's goal with the recreation area is to make it accessible to local residents. The users are mainly influenced by the accessibility therefore clearings and thinnings are appreciated.
Gränsdragningsproblemet i luck egalitarianism
The purpose of my study is to investigate whether luck egalitarianism can be savedfrom its inability to draw a line between risks which can reasonably be expected to beavoided, and risk which can not. Such a demarcation is of particular importance forthis influential theory of distributive justice, since it serves to judge whether a personis entitled to compensation for a bad outcome of a taken risk, or not. Testing theintuitiveness and coherence of various contending principles for how to separateavoidable risks from unavoidable ones, I conclude that luck egalitarianism seemsunable to draw a clear line between the two kinds of risks. Instead the theory appearsto be dependent on conceptions of a 'normal life', making it remarkably vague.Furthermore, I argue that luck egalitarianism seems unable to manage without takingsufficientarian and utilitarian concerns into account, for the purpose of decidingwhich risks are avoidable, and which are not..
Value-at-Risk : Historisk simulering som konkurrenskraftig beräkningsmodell
Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.
På färd genom glömda landskap : Rumslig analys av bronsåldersbygden i Mönsterås
This paper deals with the relations between landscape rooms and monuments in an area north of Mönsterås in Kalmar län. After archaeological excavations had been carried out in the area 1991, an article promote it to the ?Bronze Age district of Mönsterås? (Källström 1993). There are two main problems that I deal with in this paper. First: The relations between the natural places and the monuments or memorials.
