Historien om en svensk säkerhetspolitisk agenda - Förklaring av processen, politiken, policyn och entreprenören för Sveriges militära insats i Tchad

The aim of this study is to analyze the process of an agenda setting and see how a specific issue came to materialize on the security policy agenda. The empirical goal of the study is to see why Sweden chose to participate in the EU-led operation to Chad, and how that process came to be? The analysis is based upon Kingdon's multiple streams theory (2003) where he distinguishes the process into three streams. Central for his theory is the coupling of these streams and the importance of a policy entrepreneur. I complement Kingdon's theory of policy entrepreneurs by taking inspiration from Hinnfors (1995), Gustavsson (1999) and especially Eriksson (2000) and their analysis of policy change and agenda setting.

Att Visualisera Oron : Hotet, subjektet och terrorattentatet i Stockholm 2010

This study examines which socially constructed threats and subjects of security existed during the aftermath of the terrorist attacks in Stockholm 2010. With ideas of identity and difference as a starting point the theoretical framework is then developed with ideas from the new critical security studies including key subjects such as attributes, risk, imaging and visualisation. The study will be executed with the use of a discourse analysis approach using newspaper articles and chronicles as the principal empirical material. The analysis will then follow two separate themes. Firstly, the different threats and subjects of security will be deduced, and also, how these social constructions inevitably create each other and require each other to continue existing.

Tillämpning av Unified Process och Design Patterns vid integrering av system

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

Datoranvändning : En diskursanalys av medias attityder till dator och surfplatta

The essay is a discourse analysis of the media's attitudes toward computing. The aim is to compare what the media is really saying about the usage of tablets, computers and compare it to what the research is saying. In addition, it examines what the media says about socialization. We analyze the newspapers Dagens Nyheter and Expressen and will first compare these two together and see what attitudes that emerge, and then seek similarities and differences with the previous research and theories including socialization learning, attitudes and consumption. Conclusions we can draw is that Expressen has a more negative attitude towards the use of computers while the Dagens Nyheter has a more positive attitude, but is also more objective to what they write about.

Projekthanteringssystem

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database. Although Ruby on Rails was completely new to me, I decided to use this framework instead of PHP, which I already have a good knowledge of, because of the benefits Ruby on Rails provide.

Naturvetenskap och teknik i samspel med IKT i förskolan
