Större och mindre växtätares samexistens : Möjlig interaktion och effekt på lokal biodiversitet
The purpose of this report was to investigate to which extent local presence of large herbivore mammals (Alces alces, Cervus elaphus, Capreolus capreolus, Dama dama and Sus scrofa) covaries with small rodents (Myodes glaerolus, Apodemus flavicollis and Apodemus sylvaticus? The hypothesis was that high abundance of wild ungulates would inhibit the density of small forest rodents. The data was collected during field work within FoMA (Environmental Monitoring Assessment)/SLU (Swedish University of Agricultural Science). The Ungulate dropping inventory and rodent trappings, which is the base in this report, where performed 2012 ? 2014 in Gnesta/Nyköping municipalities (G/N) with a relatively high density of wild ungulates and Vetlanda/Växjö municipalities (V/V) with relatively lower wild ungulate density.
Change Lab - Att arbeta med lärande förändring
In order to be able to change, to maintain competitiveness as a company in a
world where rapid changes is part of the daily life, it is crucial to have
knowledge and methods in how to change. One method, originally developed in
Finland, is the Change Laboratory. This method is said to be efficient, not
only concerning change aspects but also learning, since change and learning in
this method is intertwined.
This Master Thesis (20p.) tells about the process of conducting a Change
Laboratory with a Swedish high-tech company and analyses factors in the process
that makes change possible..
Skolsköterskors användning av MI-metoden
AbstractMI stands for Motivational Interviewing, the Swedish translation of MI is Motiverande Samtal. Adolescence is a period in life when challenges are encountered and pivotal choices are being made. It is during this period adolescents form their lifestyle, which have an impact for their health for the rest of their life. MI has shown to be an effective and appropriate method for school nurses within school health care, to utilize in approaching by adolescents with risk behavior. This is because it gives adolescence to take responsibility and empowers them to make decisions regarding lifestyle-changes.

Metodik för utmattningsberäkning av svets i vibrationsmiljö
In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
En förändring av arbetslösheten i Sverige, påverkar det brottsligheten? : En ekonometrisk ansats
Finanskrisens inträde i mitten av 2008 utsattes Sveriges ekonomi för kraftiga påfrestningar. BNP-tillväxten mattades av och vi har till och med sett en negativ tillväxt för första gången sedan krisen i 90-talets början. Samtidigt har både hushållens konsumtion och näringslivets produktion rasat vilket har bidragit till kännbara effekter och en osäker tid för båda parter. Till en följd av detta har många företag tvingats avveckla sin verksamhet helt medan andra fått se över sina kostnader. Detta har i sin tur bidragit till att arbetslösheten ökat med cirka tre procentenheter mellan 2008 och 2010.
Statusbedömning av asynkronmotorer
Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..
Reflekterande eller reproducerande matematik : en jämförande studie mellan två undervisningsmetoder i matematik, det laborativa och det traditionella
In each classroom there is a teacher with good intentions wanting what´s best for their pupils. But grades and tests in mathematics from 2009 in Sweden shows there is a crack between the subject being taught and the learning child. The purpose with this research is to find an understanding from a teaching and learning perspective of which teaching method is more suitable for teaching and learning mathematics by doing a comparison between two methods. The main question is:What are the advantages and disadvantages of the traditional and the laboratory method of teaching, supported by the two keywords teaching method and learning?This C-paper is based on a qualitative research aiming to gather an in-depth understanding of human behavior.
Jämförelse mellan MultiScat och konventionell beräkning av intensiteter till koncentrationer vid analys med röntgenflourescensspektrometri
In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.
Twittra, gilla, mäta - En studie av åtta företags arbete med sociala medier
This thesis investigates and analyses the social media strategy of eight companies. How the companies measure and evaluate their activity and investments in social media channels in general, and Facebook in particular is studied through qualitative interviews. The findings are then compared and analysed. Findings indicate that companies' social media presences to a large extent are dependent on individual employees with high levels of interest for the area and that companies that have integrated social media into their others operations see more value from their efforts..
Mätning av ekosystemtjänster i jordbrukslandskapet :
Abstract
In order to make the modern agriculture less dependent on non-renewable external inputs, it
has to rely more on ecosystem services. The agricultural system produce not only food, fiber
and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of
nutrients, influencing local microclimate, pollination, biological control and detoxification of
noxious chemicals.
This study is an attempt to get a better understanding about the interaction among different
ecosystem services and different habitats capacity to generate them. An evaluation of eight
different methods is done. The ecosystem services studied are the ability to absorb solar
energy, biomass production, botanical diversity, decomposition and natural predation of
aphids.
Kan relationen mellan CSR och lönsamhet stödja svenska finansbolags undermåliga samhällsansvar? - En kvantitativ studie med beaktning av endogenitetsproblemet
Introduction: The concept of CSR was first coined in the 1950?s and refers to corporate vol-untary work to contribute to a sustainable society. In Sweden, companies within the finance sector are among the worst when it comes to implementing CSR in their daily work. The debate on whether companies should engage in CSR activities or not, is extremely relevant nowadays. Right now we are facing a time where the demand on companies to take their social responsi-bility becomes more intensified.
Multipel Skleros En kartläggning av infektionskomplikationer i samband med hematopoetisk stamcellstransplantation
ABSTRACTMultiple sclerosis (MS) is the leading cause of adult disability inSweden. Hematopoietic stem cell transplantation (HSCT) can be used as a treatment option for patients with MS where the disease has an aggressive course. The treatment is preceded by high-dose chemotherapy which lowers the patient's immune system. It is therefore of interest to study infectious complications associated with HSCT in this patient.Aim: The purpose of this study was to identify infection problems in this population associated with HSCT, and to study differences in infectious complications between this group and patients diagnosed with lymphoma who have undergone the same treatment.Method: The study was a retrospective descriptive study with quantitative data. A medical record review was conducted.
A comparison of methods to assess site index in young Norway spruce stands
This study investigates whether the site index curve method (SICM) and the growth intercept method (GIM) can be used for site index predictions in younger Norway spruce (Picea abies (L.) Karst.) stands than recommended by current guidelines. For SICM it was thus investigated whether the method could be used for stands younger than ten years, and for GIM it was tested whether a starting point for the intercept measurements could be used below the recommended
2.5 meter. This was tested based on measurements taken from experimental stands in Tönnersjöheden Research Forest.
For GIM it was found that the method can only be used when the TH-trees of a stand have five complete intercepts above 2.5 meters. For the method to be applicable beyond this, it will be necessary to adapt the underlying equations, perhaps following the Canadian example where a 1.3 meter intercept start is used. In conclusion it is not currently possible to apply the approach beyond the current recommendations.
For SICM, SI predictions are accurate for the study area already form year three.
Estimering av GPS pålitlighet och GPS/INS fusion
The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning. An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.
