The concept of function represents a major part of mathematics and becomes more significant in school during high school. Throughout history, it has been a difficult concept to define and may create challenges for contemporary students. This literature study aims to identify students' difficulties with the concept of function, as well as to account for how the definition of a function has evolved historically. The literature study has been conducted through database searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as through chain searching. The study results in identifying that students' difficulties with the concept of function primarily include the graphical and algebraic forms of representation.

The purpose of this thesis was to trace and discuss tendencies in the debate of the computerization of the libraries, in Swedish library press during the period of 1970-1999. The set-out was the issue of how the library journals, as representatives and mouthpieces of a by tradition humanistic profession, coped with a revolutionary innovation related to a field (data technology) which they hadn't any knowledge or even interest in. The examination included three Swedish library journals: Biblioteksbladet with connection to Sweden?s most established library organization (SAB); Bis which is founded upon a socialistic base and; DIK-forum rooted in the union. The analysis of the debate was partly based on three different sets of values related to data and systems development.

This study was based on a quantitative method to examine gender-related attitudes towards leadership styles among employees in trade union organizations in Sweden. The aim of the research was to investigate and understand how gender relates to attitudes regarding leadership within these organizations. The study was based on research questions related to preferences for different leadership styles and the impact of gender on these attitudes. The study incorporated previous research and relevant theoretical frameworks such as leadership theories, gender theories, and theories on prejudice against female leaders to contextualize our findings. Data were collected through a survey using a convenience sampling method, targeting employees of trade union organizations in Sweden.

This thesis gives an introduction to securitization in general and the tranching of collateralized debt obligations in particular. It does this by using a firm-value model to simulate the underlying portfolio via monte-carlo simulations.The simulations in turn give a loss-distribution from which the various tranchings of the CDO?s are derived. To get an understanding of the influence of different variables involved in the tranching the simulations are repeated several times where the portfolio variables are changed to generate different tranchings. This to give a understanding of the influence different variables have on the tranching and consequently risks involved in CDO?s in particular but also general risks and problems of securitizations..

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

The purpose of this study is to see a display on how family, gender and sexuality are produced in four same-sex parents? stories about their children?s pre-school start. The question formulations that have been used were aimed to find out what expectations and concerns parents may have on the pre-school organization, if the parents have any saying regarding the organization, if the pre-school have worked with equality and how they have been treated as a family. The method used is a qualitative study based on interviews. Four lesbian women have been interviewed on their experiences of their children?s pre-school start and after finishing the interviews the content has been analyzed from different viewpoints found in the material.

Factors such as time directive, poor diet and shift work characterize the profession and puts drivers' health at risk. Current research shows that the vast majority of lorry drivers are overweight, suffer from high stress related to work and have on average a very low consumption of fruits and vegetables.

This paper develops a theory for understanding negotiation situations involving states and indigenous peoples. Using relevant constructivist theory as a starting point, the paper develops a theory about understanding the relationship between power and culture implicit in the concept of the state. This relationship is examined in negotiations situations involving states and indigenous peoples. States are constituted by social structure and are representatives of the national culture. At the same time states are actors within the international system and a part of the culture of Westphalia.

Syftet med studien var att undersöka om och i så fall hur personer som har genomgått viktminskning i grupp upplever att de har påverkats av själva gruppen samt söka få förståelse för själva grupprocessen. Metoden som användes var intervju, där fem personer i åldrarna 32- 48 år ingick, en man och fyra kvinnor. Resultatet som framkom var att gruppen har påverkat personerna på olika sätt, till exempel genom bidragandet av motivation och socialt stöd som för många har underlättat deras resa mot en sundare livsstil. Gruppen hade en större inverkan i de fallen där personerna kände varandra och där det öppnades upp för diskussion och reflektion gruppmedlemmarna sinsemellan, något som också bidrog till lärande. Slutsatsen är alltså; Ja, gruppen har en påverkan, men hur pass stor den påverkan är skiljer sig mellan olika grupper och individerna som befinner sig i dem..

The last years? financial situation has contributed to an increased willingness from the banks to handle risks.

Det som är unikt i en akademisk miljö passar inte alltid in i en företagsmiljö. Därför kan det uppstå hinder då teknologier ska kommersialiseras. Syftet med den här uppsatsen är att undersöka hur dessa hinder kan se ut. Med hjälp av en tillämpad 4R-modell har de olika produkter, faciliteter och utrustning, affärsrelationer och organisatoriska enheter som påverkar kommersialiseringen av en teknologi kunnat kartläggas och utifrån detta har hinder identifierats. En fallstudie har genomförts där en teknologi har förflyttats från universitets- till företagsmiljö.

Teorier inom Kognitiv hörselvetenskap beskriver hur uppfattning av tal beror på två olika typer av processer. Bottom-up processer associeras med akustiska och fonetiska egenskaper hos en inkommande signal och top-down processer associeras med lexikala, syntaktiska, semantiska samt kontextuella egenskaper. Förmågan att utnyttja top-down processer tros bero på kapaciteten hos arbetsminnet. För att undersöka en skillnad mellan bottom-up och top-down samt deras förhållande till arbetsminnet har ett Speech-in-Noise (SIN) test utformats och genomförts på 15 försöksdeltagare. Testet undersöker skillnader i tröskelvärden för att identifiera ett enstavigt ord i ett uppåtgående förhållande till stationärt brus, mot tröskelvärden för att identifiera ett enstavigt ord i stationärt brus med hjälp att top-down stöd.

This work has been made in cooperation with the municipality of Eslöv and the inventory area is a part of the deepening of the municipality plan of east Eslöv. The aim of the work is to test the principle of balance in the overall planning. Later in the detailed planning process a more detailed calculation is made and a suggestion of suitable measures for compensation is made. Then the method with green area factors can be used. The goal is to balance the negative influence on the environment from the planned impacts to gain a sustainable development of the city. The principle of balance means that the one responsible for the development also has to compensate for the negative impacts on nature and landscape that comes with the development.
