Hur kommuniceras värderingarav matematik i kursplanen? : En diskursanalys av värderingar i kommentarmaterialet tillkursplanen i matematik.

This study is part of an international project, The Third Wave Project. The project aims to conductstudies with students of different cultures to see what they value as important in mathematics andmathematics learning. Part of the project involves carrying out a survey, the WIFI study. The WiFistudyaims to examine values of mathematics teaching that may affect student learning. The valuesthat are examined in this study are based on the mathematical values which are described by Bishop(1991).

Nedskrivningsprövning av goodwill : Tillvägagångssätt och problematik

Graphic profiles are a part of companies? brand expressions. The graphical values reflect the brand values the business wants to convey. They consist of different graphic elements such as logo, company sign, colour schemes, templates, rules, fonts, pictograms, formats and references to how different graphic elements should look, for example, business cards, signs and materials for websites. This thesis aims to examine why firms choose to replace their graphic profiles by studying their underlying motivations.

Optimering av SNCR-system i en biobränsleeldad panna : möjligheter till minskade NOx-utsläpp för ENA Energi

Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.

Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

Koldioxidutsläpp vid vägbyggnad - en fallstudie med jämförelse av alternativa byggnadssätt

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

Riksintressen för kulturmiljövården. Kritisk genomgång av fördjupade riksintressebeskrivningar

In Sweden, the main responsibility for urban planning lies with the municipalities. The county administrative boards are responsible for clarifying the governmental interests for the municipalities. The main purpose of this essay was to study documents with descriptions of national heritage areas in order to examine whether certain problems within these documents are still present in the most recent ones. This was done by comparing old documents with new ones. The problem with these kinds of documents has been the lack of clarification of cultural values in national heritage areas.

En exakt konst: : (Re)produktion och gestaltning av makt och normalitet genom mat och måltider i Virginia Woolfs Mot fyren

The aim of this essay is to analyze how food and meals produce and reproduce values and power relations and how these processes are portrayed in Virginia Woolf?s To the Lighthouse. Using sociological writings in the field of food consumption and production I study the structures that affect our relation to food and eating. This perspective is combined with a phenomenological view, aiming to examine how food is perceived, which is also inspired by queer theories. Using the method of close reading, the theories are applied to Woolf?s work.

Den nationella värdegrunden : en kritisk granskning av implementeringen av äldreomsorgens värdegrund i en kommun

The aim of the study was to investigate how a community motivates and ensures the implementation of its values and how this document affected personnel of meaning, vision and daily operations. The study was based on semi-structured interviews, in which nine respondents were interviewed in a city in southern Sweden. Interviews dealt with three different themes, all concerned organization or set of values. The analysis was based partly on how organizations and institutions build up and maintain their legitimacy. The analysis was also explained by the new institutional theory and its concepts isomorphism.

Ungdomars syn på könsroller : en kvalitativ intervjustudie om hur ungdomar uppfattar vad som är manligt respektive kvinnligt

This paper presents a study of the attitudes and values related to gender young people have. Five people, four women and one male, all about eighteen years old, were interviewed about their attitudes and values related to gender.Although the study is relatively small, the results are compatible with other published studies and indicate that young people, without consideration to their sex, has a very traditional view on gender. The study also indicates that the attitudes seem to be established very early in life. Probably the most important factor to determine the attitudes and values of the child is the parent's opinions. The result show that the interviewed persons did not think their attitudes and values towards gender where influenced by media, TV etc...

Dimensionering av betongkonstruktioner : En jämförande studie av BBK 04 och Eurokod 2 vid dimensionering av balkar och pelare

Today, we use BKR and BBK 04 when designing concrete structures inSweden, which will, in the near future, be replaced by Eurocode 2. When you are designing buildings, you will use Eurocode 2 Part 1-1 and with this new standard, some new rules and general rules will be necessary to adopt. To examine how BKR and BBK 04 tells apart from Eurocode 2 when designing concrete structures, one beam and one column with often common dimensions, is studied. The beam is designed with consideration of (considerate to) durability at bending moments, shear forces and control of cracking. The column is designed with consideration of durability at eccentric axial load and bending moments in cross section on account of (due to) geometric imperfections. BBK 04 has gone one step closer to Eurocode 2 than earlier editions and the things that are different, when calculating reinforcement, is how they use the partial factors.

EU som normativ makt i Vitryssland - ett kritiskt fall

ABSTRACTThe EU as a normative power in Belarus ? a critical caseBy Anna JohnssonUniversity of VäxjöSchool of Social SciencesSpring semester 2007The European Union?s identity is a much debated topic. Some say it?s a unique actor in the international arena because of the different tools it has at its disposal. Ian Manners claims that the EU is what he calls a normative power.

Påverkad av skolans värdegrund? : Elevers uppfattning av skolans värdegrund

This paper examines pupils? conception of the Swedish schools constitutive values expressed in the Swedish curriculum. The main question was, at to what extent the schools constitutive values have influenced the pupils conception of their own values. That question problematizes the relation between values, constructed and carried by central administration, and their interpretation at local level by pupils. The study was conducted with qualitative analysis which included qualitative interviews with seven pupils in the last year of the Swedish school system.

Är ny eller gammal regionalism vägen framåt? : -En kvalitativ undersökning om Ansvarskommitténs balansgång mellan demokrati- och ekonomivärden

In May 2007 a committee called ??Ansvarskommittén??, assembled by the Swedish government, came with a proposal of changing the Swedish regional structure. The committee which consisted of representatives from all the sitting parties in the parliament proposed that the present regional structure consisting of 20 county council districts and 21 counties would be reduced to between 6-9  regions called ??regionkommuner??.The purpose of this study is to analyze how the committee?s proposal balances democratic and economic values by using a qualitative method. The committee?s proposal is analyzed by a comparison in five political areas with two differentiated regional theories called old and new regionalism.

Den globala uppvärmningen : vad kommer att hända med morgondagens värld?

Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.
