Vetenskaplig publicering i gungning

Scholarly publishing has since the introduction of electronically distributed periodicals seen a time of change, mainly in the STM-business (Science Technology and Medicine). The roles of the three main participants in the publication process; researcher, publisher and library are developing into new directions. Researchers themselves are taking a more active part in the discussion, with the boycott list from the Public Library of Science organization as an illustrating example. Reforms are being launched partly as an economical and efficiency issue, partly as an increasing desire from researchers to maintain the control of scientific end result. This Master s thesis examines how the partly conflicting goals of the participants affect the conditions for scholarly publication in an electronic environment.

Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning

In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

Analys av uppföljning och utvärdering av ett arbetsmarknadspolitiskt program - exemplet friår

I uppsatsen studerar jag hur Institutet för arbetsmarknadspolitisk utvärdering (IFAU) har följt upp och utvärderat det svenska friårsförsöket. Jag undersöker om deras tillvägagångssätt stämmer överens med hur man teoretiskt bör följa upp och utvärdera arbetsmarknadspolitiska program. Hemström med fleras (2002) ?Att följa upp och utvärdera arbetsmarknadspolitiska program? ligger som huvudsaklig teoretisk grund för studien. IFAU:s uppföljningar av friårsförsöket stämmer till stora delar överens med vad man bör ha med i enkla uppföljningar av program och de har även studerat hur implementeringsprocessen av friårsförsöket har gått till.

Glycemic control is known to be important but other factors ought to be considered. Aim: The aim of this study was to describe how individual self-management influences the general wellbeing among adult diabetic patients. Method: This literature study is based on scientific articles.

Psykologstudenters tankar om arbetsliv och arbetsmöjligheter : Ett self-efficacy- och locus of control- perspektiv

Tron på den egna förmågan (self-efficacy) och upplevelsen av kontroll (locus of control) påverkar människors agerande och bedömningar av sina möjligheter. Syftet med undersökningen var att öka förståelsen för hur studenter från psykologlinjen i Stockholms Universitet bedömde sina chanser att få ett arbete direkt efter utbildningen. Fyra studenter deltog i undersökningen och data samlades genom kvalitativa halvstrukturerade intervjuer. Resultatet visade att möjligheterna till att få arbete efter examen ansågs vara goda men att den praktiska tjänstgöringen för psykologer, PTP, sågs som en flaskhals. Erfarenhet, kontakter, ålder, kön och utbildningsinriktning ansågs kunna påverka möjligheterna till att få en PTP-tjänst och påverkade också deltagarnas bedömning av sina chanser.

Riskfaktorer för förlossningsdepression samt förebyggande åtgärder ? En litteraturbaserad studie

Introduction: Approximately one in eight women suffer from postpartum depression, which can affect them for a period of weeks or even years. Postpartum depression does not only affect the mother, it also has a negative influence on the rest of the family. Postpartum depression can also lead to negative consequences for the development of the infant. It is an illness that is still considered a taboo, a fact that makes it hard to identify among women who are affected. Aim: The aim of the study was to examine cases where there is a connection between social economic status (SES) and the presence of postpartum depression.

Trådlös kamerastyrning

As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

Ekonomistyrning och Ägande: Förändras ekonomistyrningen vid ett byte av ägarform?

The purpose of this thesis is to examine how the Management Control System is affected by a change in the owner structure from family owned to not-family owned. The study also tries to identify explaining factors behind the possible effects to the Management Control System. The study is based on a comprehensive case study on the company Alcro-Beckers which, in year 2001, was acquired from the owner Lindéngruppen fully owned by Ulf G Lindén. The acquirer was the non-family owned company Kemira OY, a Finnish stock listed group. The empirical foundation mainly comes from interviews conducted with people who were/are directly connected to the company, either as employees or as representatives for the owner.

Den slopade förmögenhetsskattens effekt på arbetsutbudet

In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

Drank som proteinkälla till regnbågslax (Onchorhynchus mykiss) :

The objective of the present study was to evaluate distillers? dried grains with solubles (DDGS) as a protein source to rainbow trout (Oncorhynchus mykiss), by studying digestibility and growth measurements. One control diet, totally lacking DDGS, and three test diets were made containing 10 % (low), 31% (medium) and 51 % (high) DDGS respectively on dry matter (DM) basis. The control diet and the test diets were made to be as nutritionally equal as possible. Wheat bran was used to balance the fiber content of the diets.

Lyckas svenska hedgefonder kombinera strategisk och taktisk tillgångsallokering?

I vår uppsats ?Lyckas svenska hedgefonder kombinera strategisk och taktisk tillgångsallokering? undersöker vi om svenska hedgefondförvaltare använder sig av en kombination av alfa- och betastrategier för att på så sätt generera en högre avkastning än den som fås genom att endast tillämpa strategisk tillgångsallokering. Detta gör vi genom att titta på de lineära sambanden mellan hedgefondernas avkastning och marknadens. Våra resultat pekar på att denna distinktion inte görs bland de svenska förvaltarna. Vårt resultat kan dock vara en produkt av svårigheten att finna ett komplett datamaterial över en längre tidsperiod.

Inkomstfördelning och ekonomisk utveckling -en studie av forna sovjetstater

The economic development and industrialization that has taken place in many parts of the world during the past century has brought about a huge increase in economic welfare. During this process, it has repeatedly been debated whether the gains from economic development are shared by everyone or just a few. In the field of economics, vast research has been conducted on this particular subject ever since the 1950?s. The most famous contribution might be said to be Simon Kuznets article, Growth and Income Inequality from 1955 and the ?inverted U?-hypothesis that was formulated on the basis of that article.

Screening av prostatacancer och dess kostnadseffektivtet

Denna uppsats undersöker om prostatacancerscreening är kostnadseffektivt och speciellt studeras patientens oroskänsla vid screeningen. Till grund för uppsatsen ligger ett antal tidigare studier i ämnet och de för frågeställningen viktigaste slutsatserna från dessa belyses. Slutsatsen är att det inte, med säkerhet, går att motivera införandet av allmän prostatacancerscreening. Beroende på antaganden varierar resultaten mellan $8,400 och $145,600 per ytterligare levnadsår, angivet i 1995 års pris. Vidare saknas det fortfarande resultat från stora randomiserade studier som klart visar att screening sänker dödligheten i prostatacancer.

Ger tillägg av ARB till redan pågående behandling med ACE-hämmare hos hjärtsviktspatienter bättre hälso- och kostnadseffekt?

Heart failure is a condition where the heart is incapable of providing adequate blood supply to different organs in the body. The underlying causes of heart failure is some kind of disorder in the heart function, and require careful diagnostics. The basic symptoms that arise from heart failure is difficulty in breathing, that aggravate when lying down, and fatigue. The patients? symptoms and impaired quality of life can be in different stages depending on the severity of the heart failure.
