Introduction     Knowledge has come to be an increasingly important factor for both individuals in the labor market and companies in competition. When a person leaves an organization the knowledge often follows, and a knowledge gap is created. When knowledge is shared within an organization, the individual?s knowledge is available for all members of the organization. Knowledge can thus be converted from human capital to structural capital.

The mistakes and failures on the roof are noticed during inspection of the construction, many of the commentaries are recurring. A contractor should only need to get a commentary once and then learn from the mistake. It has in this study been brought to light that the solution is not to tell the contractors to "stop slattern", it is more complicated than that. Today, the biggest problems are found in leadership, communication, feedback of experience and that the entrepreneurs take too little responsibility.To minimize the amount of commentaries all contractors need to work with a clearer leadership where the leader is both respected and appreciated. The leader must in an effective way be able to convey all the information to all employees.

As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

This report describes the construction of a climate-cabinet for testing of HV-cards (High Voltage) produced at VG Scienta. The main part of the report describes all the different components of the cabinet. The most important parts are a PID regulator from Eurotherm model 2408, a solid state contactor (SSC), a thermocouple, a finned resistor from DBK and different fans. The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

As energy prices skyrocket and the environmental issues become more frequently debated, interest in energy-efficient buildings has increased sharply in the past decade. Because of this, the interest to achieve high air tightness in building envelopes have once again awakened, due to a good air tightness contributes to lower energy consumption in several ways and to a healthier indoor environment.As the regulations for energy consumption and controls of achieved air tightness has tightened considerably in recent years, the work regarding sheets for air tightness changed significantly for construction contractors. This thesis includes a study that aims to detect what kind of manuals, recommendations or instructions contractors working according, and how a number of randomly selected construction companies in Halland, Sweden, are dealing with the matter of high air tightness of the building envelopes. The study also includes a knowledge inventory of supervisors, site managers and skilled workers, and what their opinions and attitudes are like towards work regarding the sheets of air tightness. The results have been compared with a similar survey dated to 2004, conducted by the SP Technical Research Institute of Sweden in collaboration with Chalmers University of Technology.

The task was to deliver a solution that could be implemented in today?s production of the FH truck. To make the project successful it was most important that the end result had a high maturity level. For that reason an analysis of ergonomic, laws and regulations, and possible materials where conducted. To show that this project is profitable and can be realized a ruff cost estimated of material and tools is added to the research.

Wooden joist slabs is a common type of floor in residential buildings. Higher demand and production of residential buildings increases the possibilities of profiting by optimizing the system of joists in a variety of areas. Spring and deflection is something most people can relate to since it?s not that uncommon to hear furniture rattle when you walk over a wooden floor. To remove the presence of those kinds of vibrations the system of joists have to be made stiffer than the standard joist construction that is used in today?s constructions.

The vizualisation and creating of places is an essential part of physical planning. The notion of places as placeless, is likewise of importance for the creating of places. Some tendencies concerning architecture like modernism, as well as constructions whome don´t fit in their landscape, have contributed to the benaming and experience of places as placeless. Phenomenon as globalization and post-industrialism have in some cases conduced to the withering of the sense of place. With starting-point in litteraturestudies, observations of places and interviews, this is a lucubration concerning the means of placelessness in physical planning.

This study aims to explore how a gardening project with elderly living in Djuröhemmet, a nursing home outside Stockholm, affected them regarding psychological well-being and their experience of participation during the planning and construction of the memory garden. The gardening project is new in its kind by allowing the residents to influence the design of the garden by sharing the project leader their gardening memories from previous parts of their life and by wishing for specific plants and items.  The method being used was qualitative interviews where we interviewed seven people living in Djuröhemmet who participated in all or parts of the project. The theoretical framework is Molins (2004) definition of participation, but also theories of meaningfulness, social needs and gerotranscendence were applied. The results indicate that the participants did not realize that their involvement during the planning helped developed the garden.

?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.

This research is about the experience educationalists have of children encountering mathematics in a preschool. What is the impact of introducing mathematics in preschool? How do educationalists work with mathematics and how do they experience the children?s interest in mathematics?  The aim of this degree project is to examine how educationalists experience children´s interest in mathematics when they encounter mathematics at an early age. The degree project is limited to educationalists and children within a preschool located north of Stockholm.This research seeks answers to the following questions at issue. Does an early encounter with mathematics in preschool lead to increased interest in mathematics among children?  How can educationalists in preschool work in a appropriate way with mathematics to stimulate children to develop within mathematics and to increase their interest? How does educationalists in preschool experience children´s interest in mathematics?Theories by Piaget, Vygotskij and Dewey were used as well as former research in this subject.To answer the aim and the questions at issue in this research, three interviews was conducted with educationalists at the preschool and recorded with a Dictaphone.

Byggbranschen brottas idag med en hel del fel och brister i byggprocessen. Exempel på problem är bl.a. höga byggkostnader, kvalitetsbrister samt att det förekommer slarv och okunskap. Produktiviteten i byggbranschen har inte utvecklats lika mycket som i tillverkningsindustrin som använder sin ledningsfilosofi Lean Production.Syftet med detta examensarbete är att få insikt i vilka vanliga fel och brister som förekommer i byggbranschen, samt att kunna ge förslag till förbättringar i enlighet med lean-tänkande. När man talar om Lean i byggsammanhang benämns det Lean Construction.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

This is an interview based qualitative case study on two Women's Migrant Associations in Malmoe, which I interpret as being part of a women's movement, with characteristics of a new social movement. The aim of this study is to get a deeper understanding on how the collective identity is being constructed, in this women's movement where the membership is not based on an exclusive ethnic identity.I make a two dimensional analysis that departs from a social constructivist underpinning, including the theories Transversial Politics, Postcolonial feminism and New Social Movement Theory.First I analyze the construction of collective identity from the external social and cultural context, and get confirmed that the collective identity of the movement is based on a common experience of social exclusion and a plurality of actions that aims to fight the structural injustices based on gender and ethnic discrimination. Secondly I analyze how the collective identity is being constructed and maintained from the interactions between the members of the movement, from an understanding of Transversial Politics. My findings show that the members of the movement interact in a participatory democratic way which generally corresponds to Transversial Politics. According to Transversial Politics this can lead to a construction of an empowered inclusive collective identity for the members and as my empirical study confirms it also means possibilities for deconstruction of boundaries between social groups..
