När barn behöver stöd i skolan : Direkta och indirekta målformuleringar
The aim of this thesis was to investigate the relation between different kinds ofremedial teaching models, not specifically addressed to pupils with physicaldisabilities, in the Swedish school context, and to describe and analyze theobjectives related to each model. Research focus was held on professionaldescriptions of school related problems and arguments for different kind of models,but also on objectives formulated in Swedish school policy. As theoretical toolswere used discourse analysis and interpretive policy analysis. The concept ofalienation as it appears throughout Foucault?s work was also used to understand howdifferent knowledge fields as education, special education, psychology and medicinedivide themselves from each other.
En effectiveness-studie av KBT-behandlingar för GAD på en specialistmottagning
En effectiveness-studie undersökte effekten av Dugas och Robichauds (2007) behandlingsmodell för GAD på en specialistmottagning för patienter med komplicerade ångest och eller depressionstillstånd. Utöver detta undersöktes vilka övriga KBT-behandlingar för GAD som förmedlats på mottagningen. Alla patienter behandlades som en del av klinikens ordinarie verksamhet. Huvudutfallsmått var Generalized Anxiety Disorder Scale-7 (GAD-7) som mättes före och efter behandling. Därutöver mättes även grad av depressiva besvär med PHQ-9 samt grad av klinisk remission efter behandling.
????Att lösa reglertekniska problem med Modelica
Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.
En studie av miljöfaktorers betydelse för förekomsten av Francisella
This thesis aims to analyse relations between the risk of Francisella in endemic areas and environmental variables. The thesis also discusses relations between occurrences of Tularemia and meteorological factors. The analysis resulted in several significant models that explained the occurrence of Francisella. These models can however only be applied to the year 2004 since there were too few test performed the other years, therefore no comparisons could be made. Another conclusion was that the relative humidity was significally higher in the year 2003, the same year as the occurrences of Tularemia was at its peak. .
Risken för översvämningar vid de svenska kärnkraftverken : en statistisk och historisk extremvärdesanalys
This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .
Utvärdering av beräkningskoden APROS för användning i inneslutningsanalyser
At Forsmark nuclear power plant the rather old-fashioned software COPTA is used in containment safety analysis. There exists a desire within the organisation to introduce a more modern software with ability to more detailed modeling and increased usability.The goal of this thesis was to evaluate the software APROS in containment safety analysis. APROS models describing one of the containments at Forsmark NPP have been developed. Two simulations of typical containment incidents, one of them a large pipe break, have been made where containment safety parameters such as pressure and temperature are studied. Results are analyzed and verified against results from corresponding COPTA models.
Public Sector Scorecard : en ekonomistyrningsmodell med kundfokus
The Public Sector Scorecard (PSS) is a younger version of the balanced scorecard, created for public and nonprofit organizations. The latest model of PSS is divided into three main groups and seven perspectives, while the balanced scorecard consists of four perspectives. Organizations who use either PSS or the balanced scorecard are supposed to have a clear vision spread all over the unit. This study has sought differences between the two models of financial control in both theory and practice. The first part of the study is a theoretical comparison between the models? structures and terms used in them.
Hur skapas en journalist? : En biografisk studie på nyexaminerade journalister
The study - Hur skapas en journalist? - examines why so many people choose to turn tothe journalist profession when the conditions for a secure position on the labor market ispoor. The study also highlights how recently graduated journalist perceives their temporary and insecure position on the labor market.The study was performed trough ten biographical interviews with recently graduated journalists. Via the interviews I examined what has formed the individuals to perceive journalism as a rational or pragmatic choice for a career. The study shows that journalists, who come from families with high cultural capital, have been shaped by a particular culture of education, which focuses on education as a step towards selfrealization.
Utveckling av en diameterklassmodell för grandominerade bestånd i Sverige :
Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.
Kol-14 datering : En litteraturstudie över hur kol-14 isotopen används för datering, samt utveckling och tillämpning av djup-åldersmodeller inom naturgeografin.
This literature study concerned the use and function of the radioactive isotope carbon-14, as a dating method of organic material, within the scientific field of physical geography. In this report it is presented the need of atmospheric calibration curves and the development of these as a necessity to translate carbon-14 years to calibrated calendar years. A number of common age-depth models that is used to give an approximation of an accumulation sequence and its related dates over the actual time period in different natural archives is presented and discussed. Different problems that commonly occur when age-depth models are utilized as for instance reservoir effects, contaminations or other age deviations are addressed and analyzed. The software CLAM in presented and discussed and was also used to produce age-depth models.
Kapitalstruktur : Skuldsättningsgrad och avkastning hos svenska finansbolag
In a time when economic crises relieving one another, it is especially interesting to study how companies choose to finance their operations. Since there is a lack of studies that include banks, and their capital structures, with the rest of the finance market, it is uncertain whether the theories of capital structure are applicable. Therefore, this essay aims to study whether there is any correlation between the two variables debt-equity ratio and return on equity (ROE) for Swedish corporations on the finance market.In accordance with the theorems that the professors Modigliani and Miller filed, in 1958 and 1961, which describes a clear link between debts, increase corporate value through the tax shield and indirectly increased yields. Although these theorems are the foundation of the modern research they focus on perfect markets. Therefore, this paper has also chosen to place great emphasis on theories such as Trade-off and Pecking-order.
Metod för att mäta förändring av city logistik : - En casestudie på Sandvikens kommun
To distribute goods to customers in urban areas is necessary to support the economic and social development in the cities, but has consequences that affect both residents of cities as well as the environment. The environmental effects of these types of transport involves not only the emissions of various pollutants, but also an increased noise level inside the cities. Many companies and organizations are working hard to change the distribution pattern to streamline transport in the urban area, while environmental impact is reduced. This is in line with what is called the City Logistics. The purpose of this thesis is to create a method for describing and measuring a given transport solution in order to compare it with an altered transport solution to achieve a more sustainable development.
Det cykliska : The cyclic
In this essay I analyze the way my collection of poetry relates to the concept cyclic. What is cyclic and what different interpretations are there concerning the concept? Which other related concepts are there regarding things that seem to reoccur regularly? How does the cyclical, the circular, relate to the linear in regard, for example, to the perception of time? Life often creates the sense that different phenomena and experiences repeat themselves. Different processes are conducted according to regular or irregular cyclical phases, situations seem familiar and events can be relived. Starting from my writing project Sinnligt kviller, a collection of poems, I discuss these questions in themselves and the impact they have had on my collection. I describe the phenomenon cyclic as a result of the emotions and moods this term creates in a more or less decisive way. The intention with this paper is to show how Sinnligt kviller offers different perspectives of and reflections upon the various feelings provoked by the cyclic in our lives, feelings that are given my own voice in the literary text under study..
Tsunamin - Krishanteringens beslutsprocesser
When the Tsunami occurred on Boxing Day 2004 it caused a major stress upon the governmental agencies in not only the affected areas but also in states that had a large number of citizens in the affected area. The governmental agencies were not prepared for the demands from the citizenry in these countries to deal with rescue and crisis management in areas situated halfway around the globe. This thesis main purpose is to research what the causal mechanisms of Sweden?s and Finland?s crisis management were through the method of process tracing. Taking its theoretical stance in Allison?s & Zelikow?s three models of decision making, the thesis compares the course of events of the first two critical days in Sweden and Finland to establish what mistakes were made during this critical period.
En modell som förutsäger naturlig skogstyp utifrån geografik information
Sveriges yta täcks idag av närmare 60 % skog, varav större delen utnyttjas för skogsbruk. Hur skogsbruk ska bedrivas är omdiskuterat, och alternativa metoder till det dominerande trakthyggesbruket har utvecklats. Vissa av dessa metoder, t.ex. Lübeckmodellen, utgår från naturliga förutsättningar för att producera en skog som lämpar sig på en given plats.Syftet med denna studie är att utveckla en modell som med enkla GIS-data översiktligt kan prediktera naturliga skogstyper utifrån andra variabler än befintlig skog, då den skog som finns idag ofta är planterad och därför inte alltid avslöjar en plats naturliga skogstyp. Förhoppningen är att modellen ska kunna vara användbar vid skötsel av och omställning till naturlig skog.Studien baserades på skogsområden vars vegetation antogs vara naturlig (naturreservat, nyckelbiotoper o.dyl.) i Askersunds kommun, Örebro län.
