This bachelor thesis consists of an analysis of museum environment. In the research, case studies have been done at the, Stockholm based museums, Swedish museum of Natural history?s exhibition Natur i Sverige (Nature in Sweden) and the Nordiska museet?s (Nordic history) exhibition Modemakt (Power of fashion) and learning environment Lekstugan (playhouse). The purpose of the research was to study how cultural heritage is used and developed within the museum pedagogy aimed at children. The research is based on a multimodal approach with focus on learning resources.The research examines the museums focus on children and youngsters, what the goals for this focus looks like on respective museum and how the focus is visible in the actual museums.
Effekter av fysisk aktivitet på psykisk ohälsa hos unga kvinnor
Among young adults and especially women, psychological issues are common phenomena in the society such as depression, anxiety and stress. Research has shown that physical activity can be a complement for anti-depressant medication. The aim of this review is to examine previous research to find out how physical activity can provide positive effects on overall mood state in particular young women's psychological health. The results of this review is that there are support in the literature of young women that physical activity may enhance mood in studies of depression and anxiety symptoms and small support for the effects on reducing stress. Physical activity with both high intensity and low intensity has shown to have positive effects on depression and anxiety, but the physical activity has to be regular for long-term effects.
Smarta elnät i Sverige : Energibranschens förutsättningar och förväntningar
The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for smart grid solutions. However, the rapid increase in wind power might push the development of a smart grid in the coming years.
"ESS avgörs i Bryssel": Nätverk söker förankring i institutionell beslutsstruktur
This paper aims at describing and explaining the bi-and multilateral negotiations that are, and have been, taking place between Sweden's chief negotiator Allan Larsson and European countries, and within the EU institutions in Brussels, in order to seek support for the Swedish offer to host the European Spallation Source, ESS. It applies a case study method using political science theories ? governance and government ? and to a large extent information from the involved actors in the policy process. The paper also presents a constructive position, in showing how the negotiations on ESS can turn into a process leading to a decision on the construction of this research facility. ESS is negotiated in networks on bi- and multilateral levels consisting of European research representatives and financiers.
Gapet mellan teori och praktik i pappersprototypande : en studie i diskrepans mellan det ideala arbetssättet akademin förespråkar och hur praktikern faktiskt arbetar
This study presents an alternate viewpoint to the strive to overcome the gap between research and practitioners within paper prototyping in interaction design. Earlier research identifies three aspects of this gap, which is:Practitioners being unaware of interaction design methods and theoriesPractitioners being aware, but choosing not to apply these methods and theories, due to time, budget and constraints of labourPractitioners and research having different perspective on similar design issuesOur study was done by carrying out qualitative interviews with interaction designers based on two digital design bureaus. One of the bureaus has an expressed link to research: the other has not. Our hypothesis is that the gap would manifest as a difference in work practice between the two bureaus.Our study shows that the two bureaus have similarities in work practice and that this work practice is based on scientific methods and theories, but is adapted to fit the client and/or the project. We conclude that the overcoming of the gap might not be necessary.
På jakt efter den produkt som flytt - en studie om uppskjuten produktlansering och dess effekter
Many product launches are postponed today, however very little research regarding to customer responses to such events has been carried out. The purpose of this paper is to investigate how people react to a postponed product launch. An experimental study of responses to a postponed launch of a mobile phone, a mineral water and a music album is used to investigate customer reactions. The respondents exposed to the postponed launch showed a higher value of reactance. This reactance affects the attitude, purchase intention and perceived quality of the product in a negative way.

Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie
This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.
Du väljer själv- En kvalitativ studie av Nya Vägvalet Rosengård
Youth crime is a subject widely discussed in media as well as in the academic field of criminology. One of the topics within the research field of youth crime discusses how to effectively help young people leave a criminal lifestyle behind. It is within this topic that the focus of this essay lies. This qualitative study examines a community based program in the Swedish city of Malmö called Nya Vägvalet (The New Choice of Path, own translation), which works with juvenile delinquents and the issues that surround the youths lifestyle. The aim of the essay is to explore the foundations and methodology of the program, how the methods of the program are put into practice and how these methods compare to what current research findings claim to be effective factors in successful interventions.
Kaffesump som substrat i biogasanläggningar eller som bränsle i fjärrvärmeverk : en studie av effekter på växthusgasutsläpp och kostnader
Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.
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.

En förstudie för bioetanol produktion i Borås
AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.
Personlighetsskillnader mellan gymnasielärare och blivande gymnasielärare : Differences in personality between high school teachers and future high school teachers
The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.
Skillnaden på ett uttalande och ett brev : - En textanalytisk studie av anklagelser och försvar under skandalen på Sheraton Stockholm Hotel
Previous research on Twitter use among nonprofit organizations has been centered on the US, thisessay Nonprofits on Twitter: a content analysis of Swedish nonprofits working for gender equalityseeks to expand that research to include nonprofit organizations operating in Sweden. By studying tenSwedish nonprofits all working to achieve gender equality this study can begin filling a gap in theexisting research. Focusing on both what kind of messages the organizations publish, and what kind ofmessages engage the organizations? followers. This is achieved by quantitative content analysis:categorizing messages into the categories Information, Community and Action, and measuring whichof these categories got the most shares, comments and likes.
