Hur social a?r den Sociala Ekonomin? : Sociala fo?retag och regionala innovationssystem

Authors: Kosovare Islami and Selma SumicDate: 2014-06-02Title: How social is the social economy? ? social businesses and their regional innovation system.Level: Bachelor thesis in Business AdministrationSupervisor: Bengt JohannissonExaminer: Frederic BillKey words: Social entrepreneurship, regional innovation system, business - to - businessThe purpose of this paper is to create a model of regional cooperation network for social enterprises as the base of an innovation. This model will be created through the empirical basis. The model proceeds from the three pillars that have been developed and include social entrepreneurship, business - to - business and regional innovation.Entrepreneurship has multiple definitions which treats such as innovative thinking, targeted and creative individuals. Social enterprise has attracted more widespread interest, while it is considered one potential solution for the development of a sustainable society.

Hästhållningen i Sverige 2009 : intervjuer med 52 hästhållare i 5 kommuner

The purpose of this degree project is to investigate how horse keepers reasons about horse keeping and how the horse keeping looks like today. It is interesting to compare modern horse keeping with ancien recommendations and how the horses were kept then to understand how much in the horse keeping today that is based on traditions instead of research and science. The degree project was based on data from interviews of 52 horse keepers in five different municipalities. All interviews have been based from the same questionaire about how there horses are kept today, what they think about different housing systems, how they think horses will be housed in the future and what problems they think are the biggest in horse keeping today. The results shows that single boxes indoors are the most frequently used housing system today.

Bokbloggen i de litterära kretsloppen : En litteratursociologisk analys

This thesis explores the position of book blogs in the literary system through Robert Escarpit's socio-literary model of the book market. Simultaneously the thesis serves as a test for Escarpit's theory: by actively applying his theory and model to a very new and contemporary actor on the book market I hoped to reach or confirm new insights into the usefulness and validity of Escarpit's work for contemporary socio-literary studies.Three book blogs were selected for the analysis and interviews were carried out with the authors. The interview questions were formulated specifically for the purpose of extracting the kind of information necessary for an analysis using Escarpit?s theory. As a complement to the interviews, statistics on the type of books reviewed on the blogs were also compiled.

Beräkning av energianvändning i svenska småhus

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

Marknadens riskpremie ex-ante på Stockholmsbörsen

Resultaten visar på att abnormal earnings model är en mertillförlitlig modell i förhållande till dividend growth model. Dettafrämst då abnormal earnings model grundar sig på mer tillgängliginformation samt att tillväxträntan i dividend growth model harkonstaterats vara orealistiskt hög. Analytikers prognoser tenderaratt vara optimistiska i början av undersökningsperioden 2000-2002. Perioden 2003-2007 präglas mer av pessimistiskavinstprognoser. Marknadens riskpremie fluktuerar mindre underperioden 2005-2007, vilket kan förklaras utav införandet av IFRSår 2005..

Modellbaserad temperaturregleringav partikelfiltrets regenereringsprocess

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

????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 analys av steg och konsekvenser vid införande av MVC

Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

Evaluation of Xilinx System Generator

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

Valfrihet inom den svenska hälso- och sjukvården: En studie av patienters beslutsfattande

Citizens? freedom of choice has been a subject of debate in Sweden for over 30 years. This study focuses on decision making processes among patients within the Swedish healthcare system. The main conclusions are that in contrast to how patients? freedom of choice is described within governmental bills and governmental inquires and reports, patients are not following the steps included in the rational model of decision making.

Åsktransienter och överspänningar : En spänningsfylld simulering av elkraftsystemet vid Forsmark 3

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

Den svenska modellen och dess framtid

This study reflects on the swedish model and the models future. The swedish modelmeans that legisilation acts with the collective agreements . The wage issue is notregulated by law instead it is managed by the social partners in the form of collectiveagreements. In 2008, a report was presented by the Commission on a joint regulation ofthe minimum wage for all EU countries. The issue has become increasinglycontroversial and was especially disccused for the election of candidates to theEuropean Parlament last spring.

Termoelektrisk lagring i system med fjärrvärmeproduktion

With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.

En studie om införandet av expected loss model : - En mer tillförlitlig och relevant metod för nedskrivning av finansiella tillgångar?

Accounting has been critized for being one of the leading factors in the latest financial crisis. One of the primary problem areas was identified as delayed recogonition of losses on financial instruments. Consequently, a new impairment model is being developed and is to be namned expected loss model. The difference from the present model, incurred loss model, is that it takes losses into consideration on an much earlier level. Even though the model may be theoretically feasible, in practice it may implicate a number of issues.

?Tillvaron [...] vidgar sig? : Alberte ? en Ny kvinna i genusomskapandets tid

This essay examines the Alberte triology, by the Norwegian writer Cora Sandel, from a gender/feminist perspective. Taking Yvonne Hirdman's theory about the gender system as a starting point I will show how the living conditions and the different roles of men and women are represented in the novel and how they are changing during the centuries before and after the First World War.I am particularly interested in Alberte, the main character, what attitude she takes to her position in the gender system and in what way she differs from the traditional female model. Is she a New Woman, a different ?species?, who doesn't fit into the rigid gender system? Does the New Woman have a male counterpart, and is he to be found in the novel? Does the novel give a positive vision of a future where men and women can meet as equals?.
