Förenliga motsatser? : En jämförande studie om aggregering och deliberation i två e-petitionssystem
This essay sets out to compare political participation in two e-petition systems: The Malmö initiative in Malmö, Sweden, and Better Reykjavik in Reykjavik, Iceland. The main question of the essay concerns the aggregative and deliberative qualities of the Malmö initiative and Better Reykjavik, as well as the relationship between aggregation and deliberation. This main question is divided into four subqueries that lead the empirical analysis. These are: (1) Which similarities and differences in terms of design are there between the Malmö initiative and Better Reykjavik? (2) To what extent have these systems mobilized an aggregative political participation? (3) What similarities and differences are there concerning aspects of deliberation? and (4) What is the correlation between aggregation and deliberation like in the two e-petition systems?The method in use is a comparative cross-sectional study with a 'most similar research design'.

Teamchefer och vårdpersonal-Deras upplevelser kring kompetens och kompetensutvecklingTeam Leaders and care personnel in homecare- There experiences concerning competence and the development of competence
ABSTRACTWe have chosen to write an essay about competence because we think that it is an important and a current subject of interest, both to us as future team leaders, but also to all activities within the community. We have a background working with eldercare and we have noticed that there are continued changes going on. This made us want to study what team leaders and their staff think about competence and the development of competence. The purpose of this study is to analyse how team leaders work to develop competence with their personnel working in home care. We also want to analyse how the personnel experience their competence and their need for development of competence.
Teknologier för fordonsdiagnostik
The capacity to extract information from vehicles has the potential to be very beneficial. Performing analysis on information about fuel usage, emission values and other driving properties of a vehicle can lead to great economic and environmental benefits.This report contains descriptions of two prominent systems for retrieving information of this nature from a vehicle, On-Board Diagnostics and FMS-Standard, and of an implementation of FMS-Standard.The conclusion drawn after this investigation is that these systems do indeed offer access to the benefits mentioned earlier, although to varying degrees and with differing prioritisation..
?Rätt avlopp på rätt plats? : ? Livscykelanalys av tre enskildaavloppsanläggningar
?Rätt avlopp på rätt plats? ? Livscykelanalys av tre enskilda avloppsanläggningarProblemen med övergödning i Östersjön och i Sveriges insjöar är stort och enskildaavlopp pekas ut som en central aktör, framförallt beträffande fosforutsläppen. I Sverigefinns det ungefär en miljon enskilda avloppssystem och nästan hälften av dessa har enså pass bristande vattenrening att de inte uppfyller gällande lagstiftning. Utvecklingenav nya tekniker för rening av avloppsvatten har länge strävat efter att minska utsläppenav övergödande ämnen, detta ibland på bekostnad av andra utsläpp, så somväxthusgaser och försurande ämnen.Det här examensarbetet har därför med hjälp av metodik från livscykelanalys (LCA)utvärderat tre enskilda avloppssystem med tanke på deras utsläpp av växthusgaser,försurande gaser samt övergödande ämnen. Då misstanke också fanns att de lokalaplatsegenskaperna påverkar de enskilda avloppssystemens totala miljöpåverkan,utfördes även en intervjustudie med ett antal av landets kommuner.
Solvärme på Utö
The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.
Livskvalitet 2-7 år efter allogen stamcellstransplantation
This is an empirical cross-sectional study with the aim to examine the patient?s comprehension about their quality of life within two to seven years after their stem-cell transplantation with reference to physical, social, emotional, psychological and functional wellbeing and to investigate if the patient groups have disease specific problems. Differences in quality of life between men and women and also between allogeneic and stem cell transplantation with an unrelated donor (URD) were studied. The measurement Functional Assessment of Cancer Therapy (FACT) and the bone marrow transplant subscale (BMT) is a 49 item, valid and reliable measure that was used. The questionnaire was answered by 43 of 47 patients (91%).There is a significant difference between men and women in physical, social and functional wellbeing.
"Se mig för här är jag..." : Pedagogers syn på synsinnets betydelse för barns utveckling och lärande i förskolan.
AbstractThe signification of the eyesight for children?s development and learning- how do pedagogues support and stimulate children with defective vision in their development and learning in pre-school?These issues are based on my purpose of the field survey investigations, where I have interviewed three pedagogues and also performed an observation.My main conclusion and results describe that the vision is the high-powered engine in children?s development and learning. It also tells us that those around the children are very important for optimum development and learning, especially when it comes to supporting and stimulating children with defective vision in their necessities. Our other senses are a compensation to make it easier for children with defective visions in their lives. But all our senses are equally important for children with defective vision as they are for seeing children in their development and learning with their whole body in pre-school.Keywords:Eyesight, children with defective vision, development and learning in pre-school, pedagogues, pedagogical support and stimulation.
Vad tror blivande religionslärare? En livsberättelsestudie om sex lärarstudenters syn på religion
With this thesis I have examined the views of religion among six comparative religion teacherstudents, with the perspecitve of their life stories. I have also examined what stance they want to take due to their personal beliefs in their forthcoming teaching. To achive this I have used in-depth interviews among the six soon examined teacher students, and within the interviews I have had a particularly focus on turning points of the students? life stories. Later on I have used their turning points in an analysis with the hypothesis of ?Rites des Passage? and ?Structure and Anti-Structure?.In my survey I have found a significant relationship between the students? life stories - inparticularly their backgrounds and tourning points - and their views of religion.
Underlag för solcellsproducerad el i Stockholm : Potential och klimatpåverkan
The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.
Apputveckling : En studie av motsättningar mellan design- och användningspraktiker ur ett verksamhetsteoretiskt perspektiv
We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.
Varför väljs nativeapplikationer istället för hybridapplikationer? : Prestandaskillnader hos hybridapplikationer
The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.
