In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

As part of an Agile developing team I have in my role as interaction designer also tried to evaluate the ?iPhone Human Interface Guidelines?. With action research I have taken actions to change the workflow and to see what there can be done to make the guidelines more motivating to use. Action 1 tried to make the iPhone components more available and it suceeded, action 2 tried to make the guideline more available in whole and did not work as it was designed to do. The guidelines did not work as a source of inspiriation and I and my fellow designer distanciated us from it.

This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

Eftersom andelen äldre som är i behov av vård- och omsorg ökar i samhället kommer även anhörigvårdare att öka och i många fall kan det innebära en tung börda, isolering och ensamhet. ACTION-tjänsten är en form av IKT-baserat anhörigstöd som kan vara ett komplement till andra former av stöd till anhöriga. Med IKT menas Informations och Kommunikations Teknologi. Tidigare forskning om vård- och omsorgspersonalens upplevelser och erfarenheter av att arbeta med ACTION-tjänsten är knapphändig. Syftet med studien var att beskriva vård- och omsorgspersonalens erfarenheter av att stödja äldre och anhöriga som vårdar sina äldre närstående i hemmet, via ACTION-tjänsten.

Directive 2006/54/EG from the European Union concerns the equal rights between men and woman and the principle of equal rights. The purpose of the directive is that the member states provide the equal rights between men and woman. Affirmative action is one exception from the principle of equal rights which is settled in directive 2006/54/EG, article 3. The purpose for the affirmative action must be to encourage the equal rights between men and women.EU has specific criteria to use affirmative action, which is created by praxis of the Court of Justice of the European Union. These criteria are that the affirmative action must involve an objective assessment, there must be equal qualifications between the person which is affirmative action and the person who is not, the positive action cannot be automatically decisive and this special treatment should be proportionate to the purpose.

By comparing the experience off interaction in a life world with a drug habit and a life world without a drug habit you might find how they differ. We asked four former drug abusers in four semi structured interviews to describe their experiences off interaction under these two circumstances. The difference between the two life worlds when it comes to interaction is that in the drug abusing life world our informants describe that communicative action has to stand back for a more goal oriented action. In the drug free life world, communicative action on the other hand is experienced as the most important action. The difference is about wether interaction is goal oriented or oriented at understanding.

In 2002 the local council of Lund, Sweden, decides to implement the UN Convention of the Rights of the Child. A number of actors, such as the state, the civil society, the political society and the bureaucracy, participate in the political process with different authority and points of departure. This thesis studies the actors´ interactions from an inside perspective by applying concepts such as political power, democracy and implementation. The methodological departure is action research from within, a local NGO, the local board of Save the Children Sweden. The results of the study indicate that governance and steering of the implementation process at the communal level is weak.

The aim of this study is to describe and understand the reasons to why people choose to become foster parents. By using the theory of action we wanted to investigate their intentions rather than their motives. The questions we wanted to answer where: How do the foster parents describe their reasons for becoming a foster home? What reasons do they give fore keeping on being foster parents? How do they comprehend their task and the fulfilling of it? The study was performed by utilizing qualitative interviews with five foster parents, four women and one man. In the analysis we used the theory of action as a theoretical perspective.

The purpose of this thesis is to find out if principals and teachers have experience, expectations and thoughts about the differences that the new Education Act means in relation to the old one about action programme. Through qualitative interviews with two principals and four teachers, I have tried to answer my research questions that I have made based on the purpose. The questions are: How do the interviewees describe the routines about action programme?  Has, according to the interviewees, the routines been changed with the new Education Act? How do teachers and principals experience the differences between the old and new Education Act regarding the action programmes?The results of my survey shows that the process of action programme is different at different schools and that it has been adapted to the new Education Act in varying degrees. These results give differences in the experiences of the new directives.

The aim of the present paper was to see why a recommended course of action is not always followed in the way it is supposed to. The paper deals with a new method (SFA-metoden) used by The Social Insurance Agency in working with sick-listed people. Aspects that are elaborated on are local effects of the method at its introduction, case managers work conditions, and control of the implementation of the method. Two different methods of investigation have been employed. On the one hand, previous reports on the method have been analysed, and, on the other hand, two focus groups interviews, one consisting of case managers´ working with the method, and one constituted by their supervisors have been carried out.The results have been analysed in accordance with, on the one hand, the theory of street level bureaucrats and, on the other hand, certain concepts applied in the new institutionalism.

The purpose of this essay is to examine whether Sweden work according to the Swedish governments action plan on UNSCR1325 and whether Sweden implements this action plan according to an implementation theory.Initially you will find an explanation of the used method, definitions and the theory used for the study. The second part contains the research where the studied material is analyzed.The study itself is based on reports, literature and material from web pages.The result of the study shows thatSwedenworks according to the government?s action plan on UNSCR 1325.Swedendoes this trough good contact with women, multiple ways of interaction such as MOT, all female MOT: s and Gender Field Advisers who follows patrols.My conclusion shows that Sweden implements the Swedish action plan on UNSCR 1325 according to the implementation theory..

As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.
