Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

The issue of using citation based indicators in the evaluation of science is widely discussed. Only recently did bibliometric indicators become one out of many means for the allocation of financial resources for scientific research at Swedish universities. The purpose of this thesis is to discuss the issue of using citations when evaluating science. The author studied the issue from the perspective of citers? motives.

Syftet med denna kvalitativa studie var att beskriva personer med traumatisk hjärnskadas erfarenheter av fritidsaktiviteter. Den undersökta gruppen bestod av sju personer i åldern 26 ? 54 år. Tid efter traumat var minst två år. Datainsamlingen genomfördes genom individuella semistrukturerade intervjuer och analyserades utifrån kvalitativ innehållsanalys enligt Graneheim och Lundman (2004) och resulterade i tre kategorier: ? Personliga begränsningar vid utförandet av fritidsaktiviteter?, ? Förändring av utförandet eller annat val av fritidsaktiviteter?, ?Miljöns påverkan av utförandet av fritidsaktiviteter?.

All since Thomas Kuhn?s strongly influential The Structure of Scientific Revolutions the Philosophy of Science and ?even more so ?the Social Sciences have contained a greater amount of theories that could be described as more or less relativistic, meaning that the standards of justification or truth thereafter more often were said to be relative to language, culture, or biological makeup. One of the more elaborate ways of developing Thomas Kuhn?s theories in a more relativistic direction ismade by the philosopher Richard Rorty. Rorty, mainly a supporter of Thomas Kuhn, is also a philosopher who has been seen as a main exponent of a so called Postmodern philosophy.My intention in this thesis is to evaluate whether Kuhn's and Rorty's theories of science and knowledge could be regarded as relativism, in respects of their view of incommensurability, rational argumentation, and of their position vis-á-vis the more conventional picture of scientific knowledge and truth.

The last few years have been characterised by increasing online communication and the emergence of social media, made possible by Web 2.0. In society as well as in research, social media is used for knowledge produc- tion and networking. One example of this is Mendeley, a social reference management tool. With answers from users all over the world, this study investigates the use of Mendeley, if the respondents use other social media and if all of this affects scientific communication. The aim is also to study what the respondents think about the future of scientific communication and if this can be related to current tendencies.The theoretic framework for this study is based on Leah Lievrouws research on the Cycle of Scientific Communication and the relationship between the ?Little Science 2.0?-scenario and the ?Big Science Retrench- ment?-scenario.A qualitative web based survey was conducted (41 answers) and complemented with an interview with a professor in environmental sciences.

Rapporten huvudsyfte är att beskriva hur vi genom användning av språk och kommunikation har kunnat tillgodose våra användares krav på ett ärendehanteringssystem, samt på vilket sätt vi har använt artefakter för att kommunicera. Vi kommer att beskriva olika delar av projektet där språk och kommunikation har haft centrala "roller" och visat sig ha olika betydelse beroende på de personer som medverkar och i vilken miljö situationen har utspelat sig. Rapporten behandlar även hur resultatet av ovanstående har lett oss in i en utvecklingsprocess där vi försökt tillgodose användarens krav på bästa sätt. Vi kommer också att beskriva de kända och tidigare okända metoder som vi använt oss av för att uppnå vår målsättning, att överlämna en första prototyp av ett ärendehanteringssystem..

Secondary schools have for decades debated whether they promote social reproduction which is considered to generate the homogeneous student compositions. The gap between the academic programs and vocational education programs is considered to increase. What in recent years has appeared in research is that the gap is increasing most tend to be in the specific academic program, particularly in science. This paper's intention is to describe the science program at a local level and the pupils who were admitted to the science program autumn 2009 on the basis of an educational sociological perspective. The survey consisted of a census in which all students were given the opportunity to answer a questionnaire.

The aim of the literature review was to illuminate the importance of nutritional management to patients who have sustained a traumatic brain injury (TBI) and describe nurses responsibility and meaningful function in the nutritional support. TBI patients tend to be associated with hypermetabolism and hypercatabolism, resulting in negative nitrogen balances. The results reveal increased energy expenditure and assessments of needs energy requirements at the TBI patients. This study determining the route of feeding: enteral versus parenteral nutrition. Furthermore describes complications associated with enteral feeding.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

The purpose of my study is that I have examined children age 4 years and 5 years of their perceptions about the body's internal organs, and if they know where they are sitting in the body, and what their perception of organ systems. I have compared their perceptions and thoughts about the internal organs, to see their similarities and differences it is about childrens perceptions and thoughts dependent if they is 4-respektive 5- years old.The results that I got from my examination was that they showed me a big variety by their earlier perception about the organs. Some had knowledge of the name, some had of the function and some of the place of the organ brain, heart, lungs, stomach, liver and intestines. All these knowledge about the organs was a variety on and you could see similarities and differences in the different ages. One example about a different is that it was a four year old child that could the name of the stomach and the stomach function while there was three five years old children that could the brains name, function and place..

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.

Detta arbete behandlar hur Bluetooth fungerar samt säkerheten kring Bluetooth och några allmänt tillgängliga attack verktyg. Syftet med uppsatsen är att försöka fastställa hur säkert Bluetooth är i dagens läge. Bluetooth har länge varit tillgängligt för att utbyta data över korta avstånd. Därför har man valt att implementera det i kommunikationsenheter som mobiltelefoner och laptops med mera. Det har funnits en debatt om hur säkert Bluetooth är. För att kunna genomföra denna undersökning så har vi satt oss in i hur Bluetooth fungerar, vilka allmänt tillgängliga attacker och implementationer av dessa, som finns.

Detta magisterarbete fokuserar på kravhantering i systemutvecklingsprocessen. Mer specifikt handlar det om uppdatering av kravspecifikationen då nya krav tillkommer. Detta är en aktivitet som ofta förbises och jag har velat se varför samt vilka konsekvenser det kan leda till. Det referensföretag där undersökningen utfördes är ITT Flygt i Emmaboda och Solna, som har intern utveckling av system för sin verksamhet. Tillvägagångssättet i undersökningen har främst varit intervjuer, men även studier av de dokument som finns i verksamheten.

As more and more people gain access to broadband in their properties, the security threats get bigger. A lot more people also have computers that they carry home from work where they store important information concerning the company. The information stored on theese computers can be very easy to retrieve if you have the will and the skill to do it. Very few people have any knowledge how to protect themselves from theese threats..
