Teknikimplementering vid muddringsprojekt : Viktiga faktorer vid teknikval samt olika aktörers betydelse i processen

There are today large amounts of contaminated sediments in the Baltic Sea. These contaminants are the result of many years industrial activity where the contaminants have not been taken care of and just released out in the water. When ports want to dredge in their fairways and harbor areas the contaminated sediments need to be considered since they are a environmental risk. The development in this area has been slow and new techniques have just recently made its way into dredging operations in the Baltic Sea region. As a result of this there are no clear methods for implementing new techniques today.

?Du måste låna en riktig bok!?: en forskningsöversikt om barns och vuxnas syn på faktaböcker för barn

The aim of this research review is to map research about how children relate to nonfiction, and how adults, represented by parents, librarians and teachers, relate to children?s nonfiction and its possible purposes, and also the similarities and differences between them, according to current research.A theory of three different ways to look at reading is applied to the material concerning adults? views of children?s nonfiction. To show children?s views, themes are extracted from the research material, using an analysis model of four different ways to read.Studies show that most children as well as adults perceive children?s nonfiction in a traditional way as a means to gain knowledge and facts, and primarily related to school work.Nonfiction can also help children with reading difficulties to practise reading, by stimulating their interests. Many children read nonfiction because they prefer to read ?real stories? about actual people and events.

Enkätundersökningar i teori och praktik - med inriktning på folkbibliotek

The purpose of this thesis is to study to what extent the methodological theories are being reflected in the construction of user surveys at public libraries in Sweden. The study has been conducted as a qualitative literature study in two parts. The first part is an examination of literature concerning survey methodology; the second part is a study of three user surveys conducted at Swedish public libraries after 1995. Our main results indicate that the theories about methodology are followed in part, though it cannot be determined whether this is due to any actual methodological studies, common sense, or just copying other surveys. In our study we have found some areas of user survey construction that need further attention and that would benefit from more extensive methodology studies on the part of survey designers.

Inomföretagshandel : en deskriptiv studie av de gängse ekonomiska modellernas förmåga att förklara inomföretagshandel

This essay in economic geography describes what intra-firm trade as a concept is and different ways to determine in which cases trade is to be labeled as intra-firm trade (IFT) or not. The method used by the author is most easily described as descriptive. This method was chosen in order to test if existing theories; classic and neoclassic economics, new trade theory and international business studies, are capable to explain the phenomena of IFT. The theories are tested trough primary and secondary literature but also trough reasoning by the author.The conclusion is that the most reasonable way to determine whether trade occurs intra-firm or not, is to decide upon a 5-% rule where it when one part owns 5-% of the voting strength in the other company is to be considered intra-firm trade. This is a conclusion based on several reasons; the strongest one being that a common view on IFT could boost comparative studies as the U.S already collects data based on the 5-% rule.Classic and neoclassic economics are incapable of explaining IFT as aprerequisite for these theories is that markets are perfect.

Projektering av småhus med solvärme som huvudkälla

In this report a study has been done regarding different heating systems on which are the mostcomprehensive with solar heating systems. The report has also been focusing if solar power can beused as a primary heating source for supplying more than 50 % of the buildings total heatingproduction. The University of Dalarna constructed a demo-house for this purpose and according tocalculations the total solar usage is more than 50 %. This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.
