A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Bakgrund: Tidigare forskning har visat att insynspersoner tenderar att överavkasta påinvesteringar i eget bolag. Det råder dock delade meningar kring varför insynspersonertenderar att överavkasta. Vid genomgång av tidigare studier påträffades ingen kvalitativstudie, varav vi ansåg det vara av intresse att studera fenomenet genom intervjuer medinsynspersoner.Syfte: Uppsatsen syftar till att studera och kartlägga motiven bakom insynspersonersköp- och säljtransaktioner i eget bolag. Med hjälp av tidigare forskning samt en ny infallsvinkeli form av teorier inom behavioural finance analyseras varför insynspersonertenderar att uppnå överavkastning på investeringar i eget bolag.Genomförande: Studien har genomförts med utgångspunkt i åtta intervjuer med insynspersoner.Resultat från tidigare studier på området låg till grund för vilken informationvi med intervjuerna ville uppnå djupare förståelse kring. Den insamlade empirinhar analyserats utifrån empirisk forskning och teorier inom behavioural finance.Slutsats: I studien presenteras en ny hypotes vilken förklarar insynspersoners överavkastningsom en följd av befintlig lagstiftning.

The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa). This was done by using patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use.

Globalization has among other tendencies led to the emergence of new ways of doing business. One of the ways for organizations to meet the demands of a new competitive landscape has been through management accounting change, a field which has become increasingly popular in research. This paper builds on that research and seeks to investigate the case of the implementation of a new management accounting system in a Swedish company which was triggered by strategic change. Commonality through the interactive approach is by some researchers seen as a key to successful change. This approach is contrasted to the importance of symbolic constructs and change recipients? cognitive effort to understand the meaning of change for which Framing theory is applied.

The purpose of this study was to examine the relation between self-determination theory and its three basic needs: competence, autonomy and relatedness, and commitment to change in an organizational change. Another purpose was to examine if the quality of the communication and the effects on the organization and way to work can predict commitment to change. Considering that organizational changes is very common today there is an interest to ease and improve the change process. The survey contained the scales Commitment to change scale and Basic need satisfaction at work scale and the participants were 39 office-workers who recently had gone through an organizational change. The result indicated that it?s possible to predict commitment to change from self-determination theory, communication and effects on organization and way to work.

In 2003 the deciding political council in Bromölla municipality requested that an overhaul on the committee and public administration structure should be conducted. In the report Bromölla was characterized as a traditional organization with a low degree of change. This case study will examine why the organization previously has been reluctant to change its structure and why they are willing to do so now. In the pursuit of this objective I conducted document studies, interviews and observations. I have used theories on, institutional change and organizational culture to enlighten this.My findings shows that the traditionalists within the organization has greatly affected this reluctance towards change, in the deciding council 39 % of the representatives are 60 years or older.

When an organisation is going through a work of change, it is highly important that both management and employees has a healthy communication in order to make everybody feel involved. It is then important to be observant for both the managements and employees thoughts and ideas.This study has been performed on an upper secondary school which is performing a work of change. The change has divided the employees in three different groups. One, which thinks the change have evolved the organisation to something better. The second group of people means that it is preventing individual development of competence.

The UN has a goal to gender-mainstream all politics, but its politics in climate change is not gender-sensitive. The Swedish government has the same goal concerning gender mainstreaming, but does the Swedish politics of climate change reach this goal? The aim of this paper is to examine the relations between the Swedish politics of gender and climate change. In addition, the aim is also to investigate how gender is constructed in the climate politics. To reach these aims, an institutional, policy and gender analysis is used.

This thesis aims to describe and characterise the foreign policy change the United States has experienced towards Europe. This thesis claims that the United States is presenting a more supportive attitude today towards the development of the European Union. This more positive attitude has developed during successive U.S. administrations and has become visible since the end of the Cold War.Washington is today less ambiguous and less ambivalent towards the integration of Europe. The United States appreciate that a common foreign- and security policy in Europe is in accordance with American interests.

AbstractPurpose/Aim: This essay deals with The Swedish Red Cross Society and their work concerning strategical information and communication about HIV and AIDS in the Swedish context. In a broader sense the relation between the global and the local will be investigated and a discussion about what it means to work in an organization operating on a global arena will be held.Material/Method: This essay is based on relevant theories about culture and health communication which I have studied, selected and put together, with purpose to analyse The Swedish Red Cross Society and their informational work with HIV and AIDS- prevention. Furthermore I have interviewed four of the organizations co- workers to collect data about their experiences in working in the Red Cross organization with this specific mission. Moreover I and my colleague Hillevi Good attended at seminars and lectures to observe activities held by the organization and to get inside information about what people working with HIV and AIDS are discussing and considering as critical issues. The study holds a qualitative approach focusing on understanding this typical case rather then generalizing facts in a larger sense.Main results: The Swedish National Society of The Red Cross has a difficult mission in their work to inform the public about HIV and AIDS, although it is the perfect organization when it comes to communication due to their well-known profile and a huge geographical spread.

The increasing competition is making increasing demands of today's businesses to be changeable. Change projects have therefore become increasingly common in order to satisfy market expectations. These projects have often proved difficult to implement and fail rather than succeed. There are many people who reflect on why this is and theorists are increasingly reasoning about the importance of communication in the change process. This is something that has given rise to a new area of expertise called change management.
