En studie av IT-miljön och dess användning inom förskolan

The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter  in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.

Observatörer för skattning av verktygspositionen hos en industrirobot : Design, simulering och experimentell verifiering

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.

Påverkan av skuggor från vindkraftverk

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Jämställdhetsutbildning och jämställdhetsarbete bland sjukhuschefer

This paper is about research carried out at a hospital at which managers had taken a course in gender equality. The aim was to get a deepened understanding of them and their work on gender equality. I wanted to find out if they themselves felt that they had obtained any new knowledge and if they had changed anything at their workplace because of this new knowledge. I also wanted to know if they had experienced any problems in this process. I found that the course has been more or less decisive in order for them to start working with questions concerning gender equality.

Handel med utsläppsrätter inom EU - Möjlighet eller papperstiger

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.

Stubbtransporter - en jämförelse av tre olika transportsystem

In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

Etablering av småskaliga biogasansläggningar i utvecklingsländer - kriterier för framgång

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Private equity företagens styrning av sina portföljbolag.: Två fallstudier av relationen mellan private equity företag och portföljbolag.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

''Jag lever i ett förhållande där min kvinna slår mig'' : en kvalitativ studie om kvinnors våld mot män i nära relationer

The purpose of this study is to gain a deeper understanding of women's violence against men in intimate relationships, get an idea of ??what forms of expression that this type of violence has and to highlight the men's experiences of violence.There is little scientific research in the field in Sweden. Crime Prevention Council has determined that eight percent of all complaints involving domestic violence in 2010, reported by men over 18 years. You can only speculate on how large number of unreported cases is among abused men. The international studies highlight that the abused men feel ashamed of having been subjected to violence by a female partner.I have been based this essay on two theoretical premises, Per Isdal theory of "violence perspective" and Elaine Bergqvist's definition of the suppression technique.The study was conducted through a qualitative content analysis.

Överklagande och dess roll inom bostadsbyggandet : En granskning av plan- och bygglovsprocessen

The aim of this diploma work was to obtain a review of the appeal process in Sweden under the Planning and Building Act and the possibilities of appeal in the planning and building permit process. The work was intended to identify potential problems surrounding the appeal process and possible efficiency measures. The goal was to form a report that provides a satisfactory overview of the appeal process in theory and practical application as well as provide relevant concrete proposals on how the appeal process can be streamlined.Background and facts surrounding the work were taken from different types of literature and through several interviews with representatives in government, industry and politicians.The main problems related to the appeal process are in the long processing times and the high number of appeals. There is a great interest to streamline the appeals process and the government is going to launch studies in which possible future actions will be investigated.It is possible to appeal for up to two instances before you need a so called ?leave to appeal? in order for your complaint to be passed on to the next instance.

Utvärdering av näringsstatus inför återskapande av kalkkärr vid Hagebyhöga, Östergötland

Calcareous fens constitute a specific habitat which is uncommon in Europe and protected by the EU habitat directive due to its importance to several threatened species. Hagebyhöga in Östergötland is a calcareous fen habitat included in the Natura 2000 Networking Programme. Adjacent to the existing fen, a degraded fen area is situated. The area has been used for agriculture for several years but is now going to be restored to its former state by the county administrative board of Östergötland.When working with restoration of degraded fen areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen.The purpose of this study is to bring forth useful knowledge for restoring the degraded calcareous fen of Hagebyhöga.

"Juridik och lagstiftning är inte svart eller vitt" : En kvalitativ studie om hur skolpersonal tolkar och tillämpar skollagen gällande nätkränkningar

The aim of this essay was to gain a deeper understanding about how school employees interpret and practice school law regarding cyber-bullying that occurs between pupils on the internet. To examine this we used a qualitative method. We completed eight interviews with five teachers, one headmaster, one school welfare officer and one special educationist. These eight school employees were from four different high schools. In our interviews we found that the school employees thought it was difficult to define different concepts within the school law such as in association with the occupation and offensive behaviour which prohibits them from interpreting the school law in the same way.

Arbetsstugan och Barnkrubban : om etablerandet och drivandet av två barnavårdande verksamheter i Karlskrona 1899 - 1943

During the end of the nineteenth century and the beginning of the twentieth century Sweden experienced social changes. The proceeding industrialization led to a process of urbanization where people were forced, more or less, in to the cities to find work. The traditional agricultural self-sufficiency society was successively replaced by salaried employment. This meant that family and home was no longer the major centre of production, nurturance and care. In order to support themselves and their families, even women applied for industrial work.
