En kvalitativ studie om några elevers lärande med portfolio som redskap och metodÅr: 2008 Antal sidor: 47I föreliggande studie är huvudsyftet att utveckla kunskap om elevers och pedagogers kvalitativt skilda uppfattningar av vilket lärande som elever utvecklar genom arbete med portfolio. I ett vidare syfte jämförs skillnader och likheter av uppfattningar.Bakgrunden sammanfattar kort vad portfolio kan innebära. Forskning kring reflektion, metakognition, värdering och bedömning kopplas som centrala element till portfolioarbetet.Studiens teoretiska utgångspunkt är den fenomenografiska forskningsansatsen och som metod har använts en halvstrukturerad intervjuform. Undersökningsgruppen innefattar nio elever i år 5- 6, samt fem pedagoger.Resultatet visar på kvalitativa skillnader i uppfattningar av vilket lärande som utvecklas hos elever genom portfolioarbete.

With this paper we intend to investigate what kind of benefits there are by adding commodity futures to a well-diversified portfolio. Since the last fifteen years the commodity speculation has grown tremendously, which partially can be explained by that commodities exposes the investor to certain factors other than an investment in equities. According to our calculations the commodity futures have outperformed stocks during our research period, which partially could be explained by the increasing demand of physical commodities in developing countries e.g. India & China (Akey, 2005). By constructing different portfolios consisting of equities and corporate bonds we could investigate whether our portfolios will benefit from commodity futures and how this will vary over different levels of risk.

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

I detta arbete görs en jämförelse av tre förskolors dokumentationsarbete, förmedling av dokumentationen till barnens föräldrar och huruvida internet används som hjälpmedel för denna förmedling. De tre förskolorna skiljer sig åt i sina pedagogiska utgångspunkter, där den ena är en Reggio Emilia-inspirerad förskola, den andra en montessoriförskola och den tredje arbetar uttalat med portfoliometodik för sitt dokumentationsarbete. Undersökningen görs med hjälp av observationer och intervjuer. Resultatet av studien är att förskolorna använder sig av liknande dokumentationsmetoder men med vissa skillnader som kan återkopplas till förskolornas pedagogiska inriktningar. Montessoriförskolan är den som skiljer sig mest genom att till exempel inte ha sitt arbete med portfolio tillgängligt för barn och föräldrar under förskoleperioden, medan den Reggio Emilia-inspirerade förskolan och förskolan med portfoliometodik liknar varandra i sina valda former av synliggörandet av dokumenterat material.

The study sheds light on pupils individual plans of development and portfolios from the perspective of children. It has an ethnographic standpoint. It was carried out on children and pupils in pre-school, pre-school class and third grade. By further investigating how children and pupils use their individual development plans and portfolios, in which settings and to whom they communicate them, this study is able to grasp the discourse that is created around the instrument itself. This study is also interested in and aims to find the theoretical frame, in essence, which envelops both the construction of childhood and children?s own activities within the limitations and opportunities that this structure offers.

AbstractMarie Widerberg (2010). Portfolio i förskolan med perspektiv på specialpedagogik. (Portfolio in primary school with perspective on special education.) Sektionen för lärarutbildningen, specialpedagog utbildningen 90 hp.Examensarbetets syfte är att med perspektiv på specialpedagogik, undersöka hur portfolion används på förskolor i en mindre kommun samt belysa specialpedagogens roll. Undersökningen utgår från följande frågeställningar: På vilket sätt påverkar och utvecklar portfolion enligt pedagogerna, det enskilda barnet och förskolans verksamhet? På vilka sätt används portfolio som ett underlag till pedagogernas egen reflektion kring sin verksamhet och sitt förhållningssätt? Vilka möjligheter och hinder menar pedagogerna att det finns i arbetet med portfolio? samt Vilken roll kan specialpedagogen ha i arbetet med portfolio och hur kan portfolion användas som ett specialpedagogiskt redskap? Arbetet ger en översikt av tidigare forskning om portfolio, specialpedagogik samt specialpedagogens roll i förskolan.

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

The aim of the study is to show how a selected part of the European Language Portfolio, ELP, can support the assessment process for teachers. All the checklists at level A1 and My Language Goals from the Language Biography, a part of the ELP, are implemented and communicated in teaching in a 4th grade class of students. Two teachers are interviewed and both of their classes are compared in the study. One group worked for two weeks with the selected part of the Language Portfolio and the second group followed the regular curriculum for the same period of time. The teachers are interviewed before and after the ELP through support of mind maps.Results show that by using checklists at level A1 and My Language Goals students become aware of their own learning process.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

The first four AP-funds have a well-diversified Swedish portfolio, which is managed in similar way as the largest Swedish bank funds. Up until today, there has not been any comparable study that focuses specifically on this part of the AP-funds. Our aim is two-folded; First we will look at how well the AP-funds have managed their Swedish assets compared with Swedish funds of the four largest banks in Sweden during 2002-2006. This will be done by looking at some important key ratios and both absolute and active return. Secondly we will present a descriptive analysis of the management structure within the respective organisations, to be able to draw conclusions regarding the possible deviations in investment return.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

Background: The global capital markets have enlarged investment opportunities and thus also the sources of funds for companies which increasingly face global markets for their services and products. Huge capital movements show that investors are constantly searching ways to minimise risk and maximise returns. In the light of the substantial growth of assets in institutional funds, an important question for international finance is the degree to which institutional investors have diversified their portfolios internationally. Purpose: The purpose of this study is to examine the international diversification of portfolio investments of institutional investors in Japan, the US and the UK and deepen into international diversification in portfolios of Japanese institutional investors. Demarcations: Institutional investors can use their power directly in companies or indirectly through capital markets.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.
