?Varför är jag här? Varför sitter jag med de här gubbarna?? : En kvalitativ studie om att vara kvinna i den mansdominerade byggbranschen
This study aims to look at female executives? view of their leadership in the male-dominated construction industry. The study is qualitative and focuses on the respondents' subjective perceptions. We have conducted six interviews with women in different companies whose positions within each company varied. Using theories of subjectivity, emotions, impression management and organizational structures, to support the analysis conducted, this study shows that there are obstacles for women in the industry, but it also shows that it seems to be facing a brighter future.
Threats and opportunities for the survival of the Yangtze finless porpoise
The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.
Hur påverkar naturvårdsåtgärder mängden av vedlevande insekter : Manuellt dödade träd vs självdöda
Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.
Naturreservat : en bra naturvårdsåtgärd för att bevara enskilda arter och/eller bevara den biologiska mångfalden?
The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.
Utbilda och forska är vi bra på - men att samverka? : En kritisk studie av Högskolan i Gävle och den tredje uppgiften
The cooperation between university and industry life in the region of Gävle is always a topic of importance. University and High schools have various roles to fulfill: except administrating the training and supporting research they should also - as a third role - contribute to cooperation between organizations, business companies and other associations. In addition to that, they should support individuals by local as well as regional development. The purpose of our paper is to make a critical review of the cooperation between the University of Gävle (HiG) and industry life until today and the consequences in order to encourage students to stay in the Gävle region during and after their period of studies.Initial we started with a preliminary inquiry with a questionnaire as a base for students in three programs at the Department of Economy; the program for Bachelor of Science, the program for estate agent and another economy program with direction estate economy. From this preliminary inquiry we got the picture of the way the students looked at the problem.
The Expedition in Pursuit of Rare Meats
The purpose of this paper is to bring a British mural painting that originated in England in the 1920?s into the limelight and introduce it to the Swedish public. The mural was commissioned by Tate Gallery, currently known as Tate Britain. The work of art was designed for a semi-public space as a decoration in the Refreshment Room of the gallery, located in the basement where there was little natural light. The artist, a young British man named Rex Whistler, was transformed from being a student at an art school into a celebrated professional artist by this piece of art.
Överlevnad och tillväxt för nyplantersade barrots- och täckrotsplantor : en studie av 42 bestånd i södra Sverige
The choice between bare-rooted and containerized seedlings in southern Sweden affects
the investment costs as well as growth and survival. It is important to take these differences
into account when choosing seedling type for reforestation. The most important
differences between the two seedling-types is that bare-rooted seedlings has open root
systems whereas the roots of containerized seedlings are grown in a container which may
contain water and nutrients that are available for the seedling during the first period after
planting. Moreover, bare-rooted seedlings are often older which results in thicker stembase
and better resistance to attacks of pine-weevil (Hylobius abietis).
In order to study differences in survival and growth between bare-rooted and containerized
seedlings a survey study of newly planted clearcuts in south-western Sweden was
made. In the study tree seedling types was included, one bare-rooted and two containerized
with different ages.
The population of pine weevils was probably low during the studied period which
resulted in lower pine-weevil damage than normally found in this area.
Rosengårdens Barn och Den Svenska Kulturen
This dissertation is about children in a district in Malmö, Sweden that is called Rosengård. This district is known for its high amount of immigrants and foreigners and all the children interviewed for the study are foreigners.We wanted to bring out their story, how they experience the cultures they are in touch with, the Swedish culture that they live in and their foreign culture that they experience at home with their parents. How do these children socialize into the Swedish culture while living in a district that is hardly exposed to it? We have been working from a different perspective, this due to the fact that we have both grown up in Rosengård and are still currently living here. Therefore our perspective is more from the inside, we can relate to the children?s stories and we can tell about it in a way that seems more natural.These children are not more different than other children, they have the same interests and hobbies as is considered to be ?fashionable? in youth culture today.
Underlag för en pedagogisk turled i permakulturekobyn Suderbyn
Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..
Förskolebarns kommunikation i leken : Lek, kommunikation och språk i sammanhang
The aim of this study is to observe Swedish preschool children in their natural habitat and without any intervention. Four different observations are made and thereafter analyzed. Throughout the whole study the subject of interest is the children's communication in their play. Children can communicate with each other in various ways, for instance with speech and without speech, i.e. with their physical language, aesthetic and multi language.
Transportekonomi : Underlag för prisförhandlingar
The report addresses four main tasks, situation analysis of the company's total costs and transportation volume, cost analysis associated with the adjustment of the filling ratio, transport costs for the expansion and new expenses on a combination of expansion with new adjusted filling ratio. Increasing transport costs for the company was the main reason for the request of the current situation analysis. A survey of the total cost with the actual volumes and transport provider pricing is the basis of the analysis that extends from May 2006 to October 2008. The results show an increase in costs, both overall expense and per cubic meter of transported goods. Volume spreads, trends, and seasonal variations are according to our and the company?s expectations.
Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :
Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.
Pojkars läslust : en studie av hur pojkar uppfattar och uttrycker sitt intresse för läsning
Health and fitness are two controversial and not easily defined topics that affect people in our modern society every day. We believe that we can find a link between individualism, globalization and the stress concerning weight and appearance ideals. Our bodies have turned into a popular subject for the media, and there is no indication that the interest will decline. As the world gets more artificial, "natural" ideals are getting more attention, such as the concept of a strong and healthy body. But there is also a downside, for example with health issues such as cardiovascular disease increasing following the birth of high-fat diets.
Evenemang : -ett vinnande koncept för regional utveckling?

Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil
Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.
