Datorstöd i matematikundervisning och matematiklärande ? att simulera och modellera i problemlösning, handlar om vilka förmågor som kan utvecklas och vilka kursmål i matematik som kan realiseras i elevernas interaktivitet med programvara för dynamisk geometri. Studien baseras på en lektionsserie som bygger på en problemlösningssituation med GeoGebra som verktyg. Arbetet har en del beröringspunkter med aktionsforskning, men kan närmast definieras som undervisningsförsök. I studien görs ett försök att följa undervisnings- och inlärningsprocessen och reflektera över vad som sker.

Entrepreneurial firms face unique challenges in attracting and acquiring human resources due to difficulties associated with resource constraint and organization legitimacy, often described as liabilities of "smallness" and "newness". The aim of this paper is to examine the "smallness" and "newness" challenges met by small entrepreneurial firms, which strategies they apply to counter these challenges, and if these strategies can be explained by the firm's HR philosophy. Since few studies on Human Resource Management (HRM) in small entrepreneurial firms exist, a framework combining theory from the research fields of HRM, entrepreneurship and small firms has been developed. Employing a qualitative case study design of five small Swedish entrepreneurial firms, our findings demonstrate four "smallness" and "newness" challenges and seven strategies that either counteract or prevent them. Furthermore, results showed that the strategies applied seemed to have no significance with regards to the firm's HR philosophy.

Growth of small businesses is vital to the Swedish economy, and many entrepreneurs want their enterprises to grow. However, the business climate of today is more changing than ever, and attributes becoming increasingly important for companies in order to deal with this are flexibility, speed, and adaptability: characteristics normally attributed to small enterprises. As a larger organization often is associated with more rigidity as a consequence of a higher degree of formalization, entrepreneurs are hesitant to seize growth opportunities, as they fear it will have negative impact on the aforementioned competitive advantages their enterprise possesses as a small business. This simple case study of a growing small enterprise investigates the effects of organizational growth on a small business' organizational structure and through its above mentioned advantages. The study finds that avoiding formalization while growing damages the competitiveness of the firm, and concludes that a degree of formalization is a necessity to maintain the flexibility, speed and adaptability in a growing small business..

Venture capital firms and private equity firms have been the subject of much controversy in the last decade. During this period economies throughout the world have seen a steady increase of these types of firms as owners of companies. In Sweden this has certainly been the case and many argue that this trend will continue to grow stronger in the future. This trend is by many regarded as dangerous and as a threat to the ownership model that has characterized the Swedish economy for decades. Family ownership has been widely regarded as the most beneficial and responsible ownership model in Sweden.

Till grund för detta examensarbete ligger en ineffektiv process, samt dubbelarbete som idag utgör arbetsgången vid CAD-projektering för konstruktörer hos Structor i Karlstad. Målet med examensarbetet är att genomföra en kompatibilitetskontroll av 3D-modelleringsprogrammet Tekla Structures 15.0 mot analys- och beräkningsprogrammen Autodesk Robot Structural Analysis Professional 2010 samt Strusoft FEM-Design. Syftet är att med hjälp av kompatiblitetskontrollen utgöra vilket av programmen Autodesk Robot och FEM-Design som bäst lämpar sig att köras tillsammans med Tekla Structures utifrån valda faktorer. Två äldre examensarbeten används för att få en uppfattning om FEM-Design. För att undvika det omfattande och tidskrävande arbetet med att skapa två modeller, en grafisk samt en analytisk modell, finns en lösning. Genom att skapa den grafiska modellen i Tekla Structures 15.0, vilket sedermera genererar den analytiska modellen, och sedan exportera den via länk till Autodesk Robot Structural Analysis 2010 behövs bara en modellering.

The following essay investigates emission rights accounting. Presently there are several methods through which emission rights can be accounted for by companies. The rights can for instance be valued at fair value or nominal value and as marketable securities or intangible assets; due to a lack of consensus or clear standards companies use these or other accounting methods to value their rights. This essay investigates whether there is a relationship between the company?s choice of accounting method, the key ratio number of owned emission rights/total assets, the accounting firm used and the yearly result as a sign of earnings management.Through a quantitative study based on questioners and numbers from the annual reports three hypothesis are tested.

Machine-to-machine (M2M) communication is a phase in the digital revolution connecting computing devices with each other bringing along new business opportunities for companies. Although being a fast growing field it has not been researched to any greater extent, particularly not within the academical literature. Consequently, information on how M2M can affect organisations seems strongly needed. This thesis uses three perspectives, derived from already recognised business benefits of M2M, as an aid to select proper theoretical tools to investigate the phenomenon. The purpose of this thesis is to gain knowledge of how an M2M adoption affects a firm?s organisation, customer offerings and customer relations.

The thesis handles the principal-agency problem between shareholders and the Chief Executive Officer. The purpose of the thesis was to examine the link between CEO compensation and corporate performance measured as a change in Market to Book ratio. Data was collected from corporate annual reports between the years 2000 ? 2008 and the study covers 39 Swedish companies from the Stockholm Stock Exchange Large Cap list. To examine whether there is a link between the CEO´s compensation and firm performance, we performed a regression analysis, and no significant relation is found.

The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.

Tidigare vid ombyggnation, försäljning och förvaltning av byggnader som var uppförda innan 80-talet utgick fastighetsägarna från enkla handritade pappersritningar. Det är en svår utmaning att hålla ritningen uppdaterad till verkliga förhållanden d.v.s. relationsritning. För ca 25 år sedan (i början på 80-talet) byttes papper och penna ut mot avancerade ritprogram (CAD) för framtagning av ritningar. Idag används CAD i stort sett för all nyprojektering och de senaste åren har utvecklingen gått mot en större användning av 3D-underlag än tidigare 2D-ritningar.

China is a unique market that differs from the Western market in many ways. Companies are not required to publicize financial reports, and furthermore a heavy focus on business relationship building can make it hard for companies to have high quality streams of data to get insights about their markets. For a consultant company to successfully enter the Chinese market and helping producing and technological global firms improving their insights on the Chinese market, the consultant company needs to understand which the important factors are and how those factors can help in creating value for their potential customers. To help the analyzing and consultant firm called Kairos Future, a qualitative case study was conducted on 16 different global companies with focus on industrial production. The case study was mainly conducted through face to face interviews with decision makers who had a broad understanding of their respective companies.

Abstract: Private equity used to be synonymous with tremendous yields and rates of return. However, the private equity market trembled in 2008, due to the financial meltdown caused by the worldwide credit crisis. Considering the current low number of exits within the private equity industry, the purpose of this thesis is to examine if there has been any change in how private equity firms control their portfolio companies since the inception of the crisis. One private equity company and two portfolio companies have been studied. The case study is prepared from interviews with senior directors in the portfolio company and investment managers in the private equity firm.

Att minimera olyckor och andra tillbud utgör en central roll i samtliga verksamheter, vilket gör avvikelsehanteringen till en viktig del i utvecklingen. Försvarsmakten har ingen central avvikelsehantering utan avvikelsen hanteras lokalt på förbanden. Det finns en plan på att införa ett gemensamt IT-stöd för att hantera avvikelser bland annat för att ha möjligheten att sammanställa statistik och identifiera systematiska avvikelser. Försvarsmakten har kravställt och upphandlat ett system som tagits i pilotdrift under 2009. Pilotdriften har resulterat i ett antal frågeställningar.

Examensarbetet behandlar en modellering av hyttgasnätet vid SSAB Oxelösund AB. Det objektorienterade modelleringsspråket Modelica används. Modellen valideras statiskt och dynamiskt för olika driftsfall med gott resultat. Hyttgasen används delvis för generering av elektricitet i kraftverket. Simuleringar av modellen visar att hyttgasnätets konstruktion begränsar inflödet av hyttgas till kraftverket.

Today, Sweden has about forty companies owned by the government. These are active on markets with variable competition. Some have been given special areas of responsibility that in a practical notion make them monopolists. The period when most public companies where formed (and with that the following subjection to competition) during the nineties and early 2000's, forced the formerly protected businesses to act on the terms of the open market. Parallel to this development the brand has for the last twenty years evolved into something great strategic importance for the business, including the business-to-businesses (B2B).
