This investigation is about how teachers in school can motivate and create interest for science among younger children. Teachers were interviewed about attitudes to their subject and how this affects their lessons.I have also tried to find out, both by interviewes but also by studying litterature, what the most important thing is to teach in science, which knowledge is necessarry in the future and why.My result indicates that teachers find science both interesting and important but at the same time they also think it is a difficult subject to teach even if they are educated. Both the litterature and the teachers in my study agree that knowledge in science gives us a chance to ask questions, take stands and solve problems and that this knowledge is important for us in our future..

In 1929, the Scientific Crime Detection Laboratory was established in Chicago?the first of its kind in the United States. The purpose was to engage in practical use of scientific methods in the detection of crime. In 1930, the institute published its own periodical called The American Journal of Police Science. Applying the theory of boundary-work, this essay analyses how the novelty institute argued its legitimacy as a scientific establishment through the expansion of Police Science as a collective field of knowledge.

Denna magisteruppsats beskriver framtagande och utveckling av riktlinjer för ett system vars mål är att förändra och förbättra en organisation, där arbetet idag utgår ifrån en stationär plats men där vi hävdar att arbetssättet skulle kunna vara helt mobilt. I uppsatsen beskriver och diskuterar vi vårt tillvägagångssätt, resultatet av fältstudier och analys samt en diskussion som behandlar konstruktionen av ett mobilt anpassningsbart system. Uppsatsen resulterar i framtagandet av designriktlinjer för en mobil artefakt. Denna artefakt ska kunna stödja det arbete som utförs av personalen som arbetar med drift och övervakning av fastigheter i Karlskrona kommun. Artefakten ska vara anpassningsbar till den miljö som den används inom, den ska ha förmågan att känna av den kontext den opererar inom samt ha förmågan att följa de interaktioner som personalen utför.

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

This thesis contains a wider discussion on the analytical framework of classstudies in political science. The purpose is to put class into the light of a usefulmethodological and theoretical tool when it comes to studies on inequality and political,as well as scientific approaches and explanations to why people have awide range of differences in how they pursue their lives. It is my ambition to discusshow class relations can be theorized and explained within a given context, aswell as in society as a whole. I see the complexity of this field as a resource to enhancethe epistemological as well as the empirical discussions within the politicalscience scholars..

This report describes the development of a system for controlling documents. The report starts with a problem description which the company wants an intranet-based solution for. The report then continues to describe the development phase for the different parts of the system which results in a complete system. The company that wanted this system is called Orbit One and is located in Ronneby, Sweden. They have had a problem with old documents circulating in different versions and in different binders.

När man lever i ett samhälle där användandet av mobila enheter som smartphones ökar, sker motsvarande ökning av frågan på tillgång till befintliga system i mobila enheter. Ett mobilt system kan utvecklas på olika sätt beroende på efterfrågan och kunskapsbasen hos utvecklarna. Det finns olika sorters mobila system, däribland webbaserade och plattformsspecifika system.Den här rapporten innehåller en förstudie för olika tillvägagångssätt för att skapa en mobil version av ett system. Rapporten redogör för olika tekniker som kan användas beroende på vilket system som önskas överföras, samt vilken målgruppen är. Rapporten beskriver också hur framtagandet av ett mobilt system för olika mobila plattformar har skett för ett redan befintligt system..

This thesis examines if commercial-of-the-shelf (COTS) systems meet the needs in different types of organizations. This was investigated through a case study of a COTS system. The system is built for contact centers and used in different types of organizations. Contextual inquiries with users from six different organizations were held together with interviews with stakeholders of the system. This gave an understanding for how the system is used and the needs to be met in the different organizations were recognized.

An ongoing discussion concerning the possibilities of universal classification based on phenomena rather than on research disciplines has been noticed. In order to discover if this was a limited discussion or the beginning of a major new field of research a study of citations was made using the database Web of Science. In addition, references of the works concerned were studied to find out where the ideas originated. The study of references shows that the ideas originate in a limited number of older published works, some of them well established in Information Science, some of them less generally known. The main ideas commonly used in Information Science are Ranganathan?s facet theories and the work of the Classification Research Group.

The aim of this masters thesis is to examine the synthesis and the structure of the main class for linguistics F in the Swedish classification system SAB. We want to find out whether F has developed towards a more faceted structure or not. Our theoretical perspective is based on fundamental principles for modern classification. To carry out our investigation the first, the fourth and the seventh edition of SAB is analysed and compared. The results of our study show that the main class F has become more faceted and therefore the possibilities to use synthesis have increased.

As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.

This thesis aimed to study the interaction between an educational technology system and its users and give suggestions for design improvements. The technology system is called EDIT (Educational Development through Information Technology) and has been developed and applied at Linköping University?s Faculty of Health Science. EDIT supports Problem Based Learning and enables scenarios to be presented through the World Wide Web. The study was divided into two parts.

The aim of this master?s thesis is to investigate how Paul Feyerabend?s anarchistic theory of knowledge can help our understanding of bibliographical classification and to analyse how epistemological assumptions are manifested in bibliographic classification. Paul Feyerabend?s anarchistic theory of knowledge and science is the theoretical approach of this thesis. The first part of the thesis consists of an introduction to bibliographical classification and epistemology.

The purpose of this paper is to compare the three search engines Web of Science, Google Scholar and MEDLINE in regards of recovery efficiency and the overlap of relevant documents when it comes to information searching for academic purposes. Furthermore, it raises the question whether freely available search engines and licensed search engines are interchangeable with each other. The empirical data in this study were collected through searches conducted in the three search engines Web of Science, Google Scholar and MEDLINE. Twenty search queries were used and the first twenty retrieved documents for each query were examined for relevance using previously designed criteria. The documents were scored by a binary relevancy scale and thereafter a precision value for each search engine was calculated.
