Läraren - från ensamvarg till lagarbetare? : En studie av hur lärarrollen har definierats och förändrats i grundskolans läroplaner från 1962 till 2011.

Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.

Grundskoleelevers samlärande och undervisningen i informationssökning

Education in information seeking is often traditional and focused on technology. When it comes to this sort of education, research proves it is unusual to pay attention to the interaction between students. My intention has been to examine if it is possible to pay attention to the interaction between students, in order to create more and better situations of learning. The issues in this work are about describing the students? interaction.

Barn och sociala medier : Hur sociala medier påverkar elever och skolans arbete mot kränkande behandling

This work is about the rights of children, how students use social media and how effective teachers are using social media in their work against abusive treatment. The purpose of this work is to examine what students have rights in school, what and how students use social media and how schools and teachers are working to prevent the abuse that takes place over the internet and via mobile phones. The method used to investigate this is partly a survey of students in grades five and six at four different schools and interviews with four practicing teachers, working as a teacher in each class who made survey. My conclusion is that children have a variety of rights in school, and all schools and teachers are working on this through rules, values ??clarification and collaborative exercises. More and more younger children use out of social media, the survey shows that many of the students in grades five and six uses much social media.

Samverkan - en fråga om ansvarsfördelning och samsyn : en litteraturstudie kring samverkan mellan myndigheter och familjer med barn med funktionsnedsättning

Families of children with disabilities often have many different contacts with professional representing different principals. This places high demands on their professional work together to meet the needs of families and use resources efficiently. The method used is a literature review which aims to describe what is needed to achieve good collaboration between different professions around families with children with disabilities, and that from an organizational perspective to examine why there are often gaps in collaboration and how this affects the parents' life situation.The theories in this study originated from organizational and sociological theories. The most central concept in this study is collaboration from an organizational perspective. The results show that the interaction is problematic, due to that collaborative organizations often have rules which are incompatible and a lack of accountability on who is liable makes impairment in the interaction.

Crowdsourcing och den kollaborativa ekonomin : En studie om individers upptagande och beslutsfattande kopplat till kollaborativa tjänsteinnovationer

Crowdsourcing och den kollaborativa ekonomin är modeller för öppen innovation som blir allt mer centrala i ett samhälle som står inför morgondagens utmaningar. För att ta itu med globala problem krävs det ett globalt samarbete och ett gemensamt ansvar, där delningsekonomin kan bli avgörande. I denna kvantitativa undersökning svarar vi på frågeställningen om hur upptagandet av och beslutsfattandet kring kollaborativa tjänsteinnovationer kan se ut när vi låter 50 studenter ta del av en kollaborativ tjänsteinnovation. Vi undersöker några befintliga kollaborativa tjänster, redogör för relevanta begrepp och visar på hur Diffusion of innovations kan användas för att förstå något så komplext som hur innovationer kan upptas och spridas i sociala system. Vidare visar vi hur ramverk för konceptualisering av crowdsourcing kan användas för att förstå hur miljöaspekten och viljan att samarbeta kan driva en stor grupp människor till att dela på kompetens, resurser och kunskap.

Det virtuella kontoret : En litteraturstudie i möjligheter och utmaningar med att använda 3D kollaborativa virtuella miljöer inom distribuerad systemutveckling

Distributed system development is a common occurrence in today?s technological and global world. Because the consequences of its geographically distributed nature it creates barriers between people that affects their communication and collaboration efforts in the distributed context. Despite a lot of technological breakthroughs over the last decades and the occurrence of video-conference applications and other tools for communication and collaboration, cultural and geographical issues have so far not yet been completely resolved. In this study I have made a literature study over distributed system development to form a set of central factors that affects the distributed development process.

Locally valued habitats, species and sites and their significance for collaborative land use planning around Manusela National Park, Central Seram Island, Moluccas, Indonesia

When new land use policies are made, opinions of stakeholders need to be taken in account, to avoid future conflicts. The motivations of commercial enterprises are often clear and easily communicated but due to inaccessibility and language barriers the indigenous people?s perspectives and needs are harder to reveal. This study therefore aims to identify species and sites of importance for the local people in Masihulan village on Seram Island, East Indonesia. This is a first step to facilitate better integration of local people´s needs into local government decision-making processes.Researchers at the Center of International Forestry Research (CIFOR), with headquarter in Indonesia, have developed an approached called ?Multidisciplinary Landscape Assessment? that aims to assess important natural resources for local communities in tropical countries.

Från teckning till färdig produktion : en studie av storyboards inom spelfilm och animerad film

In this thesis I focus on the artistry and essential work, behind the scenes that storyboard artists have contributed to, since the early days of film history. The works I will focus on are the important phases of pre-planning of feature films and animated films. I theorize on the aspect of what makes a good story and how it is brought to life on the screen, as well as how the story is actually conveyed with this drawings. The hypothesis maintains the importance of storyboards, as well as defining their main purpose. Using a formalistic point of view and historical argumentation, I examine and compare five different directors´ use of storyboards and how their respective collaborative teams (i.e director of photography, production designer and story artists, editors etc) create each film´s particular nuances and cinematic expressions.

Effektmätning i pump

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

Grupparbete - formella och informella samspelssituationer : en kvalitativ studie om sex elevers uppfattning kring lärande i grupparbete

The purpose of this study is to investigate what kind of idea a group of students in third grade, who attends a school in the Stockholm area, have on group work in school and how they think it affects their learning.The study is based on two questions:What opinion do the students have about group work?What opinion do the students have about how group work affects their learning?The method I have used to retrieve information has been to interview six different students, where the interviews were both individually and in groups. I started by interviewing students individually and then had a group interview. The idea with the group interview was to end it all with a brief discussion about the thoughts that came up during the individual interviews. I chose a selection of six students, four girls and two boys which they all were at the age of 9 and go to the same school.The socio-cultural and structural perspectives, is those theoretical perspectives that my study is based on.

Utvärdering av grafisk utvecklingsmiljö för programmering av signalprocessor

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

Portning och utökning av processor för ASIC och FPGA

In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating point arithmetics.A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution..

Mätning av axiella magnetiska läckflöden i vattenkraftsgeneratorer

This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering.  To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.

En studie om studenters användning av vänlistor på Facebook

Friend lists allow Facebook users to group their friends and may be used to share certain information only with those in a specific list. This function has been around for several years, but has never gained any particular popularity among users, most of whom probably did not know it even existed a couple of years ago. In the fall of 2011, however, the function was updated and made more visible on the site.There are several possible uses of friend lists, such as privacy control, filtering of the news feed, self-presentation and targeted information sharing. This paper aims to investigate the extent to which friend lists are used by students today, as well as why students actually use their lists, i.e. for what purposes.Judging from the results of this study in comparison with earlier research, there seems to have been a somewhat recent increase in the awareness of the fact that friend lists actually do exist, but still most users tend not to utilize them.

Optimering av informationsinsamlingvid prototyptillverkning

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.
