Det finns så många olika kompetenser inom förskolans väggar : En kvalitativ studie om fem förskollärares syn på utvecklingen av förskolans kvalitet
Through a sociocultural perspectivethe purpose of this study is to investigate how preschool teachers look at quality development in preschool and how they perceive their participation in this development.I have used a qualitative method based on five interviews with preschool teachers from three different parts of Sweden. I used an interview guide with open questions. The interview answers were categorized in themes based on the responses which were most frequent. In the result I have been using an analysis based on these themes. The result showed that the preschool teachers consider that the leadership style affects their work.
Flavan-3-oler och endotel -dysfunktion
Background: Flavan-3-ols are polyphenolic phytochemicals belonging to the flavonoids. Flavan-3-ols are present in many higher plants and are particularly concentrated in e.g. Camellia sinensis (tea) and Theobroma cacao (cacao) and have got attention due to their antioxidative capacity. Many studies have been able to associate flavan-3-ol-rich foods to improved endothelial function. The aim of the present work is to review the scientific literature and evaluate the evidence for positive effects of flavan-3-ols on endothelial dysfunction in humans.
Method: Scientific articles describing intervention and observational studies about flavan-3-ols and endothelial dysfunction, were searched for on http://www.pubmed.org.
Internetbaserade distansutbildningar
In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.
"De öppnade portarna för mig och sa `hej då`" : en kvalitativ studie om personers berättelser som frihetsberövande på grund av misstanke till ett brott och tiden efter frisläppningen.
Being detained means that a person loses their freedom and have limited contact with others. Police can on suspicion of a crime arrest a person, in order that the suspected person won´t be able to eliminate evidence. Being convicted of a crime and go to prison is terrible, but what about the experiences of being detained on suspicion of a crime you did not commit? Our purpose with the study is exploring stories of people who have been detained. It´s about their time as detainees to the time they got free from suspicions of the crime.

Värdet av Enterprise Arkitektur i en verksamhet. En kvalitativ studie av hur man förklarar värdet av att använda Enterprise Arkitektur i en verksamhet i olika mognadssteg
The purpose with this report is to highlight the value which Enterprise Architecture (EA) can bring,including the effects that can emerge, for a business. In the report we also study how Enterprise Architecturemay serve as basis for generating even more business value. The study is based on a theoretical frameworkwhich covers the following perspectives; architecture design, strategy development, management of changeand evaluation of IT-investments. Gathering and analysis of empirical data has been performed using acustom-developed model which is based on a model from Sogeti called Dynamic Architecture (van DenBerg and van Steenbergen, 2006) and Innovation Value Institute?s maturity curve (Innovation ValueInstitute, 2008) for Enterprise Architecture management.Explaining the value of Enterprise Architecture is invariably an important topic since many organizationsexpect to be able to generate quick value of the investments made in Enterprise Architecture.

Bilingualism and multilingualism have always existed in Sweden. Preschool teachers must provide a stimulating pedagogical environment adapted to bilingual children.The purpose of this examination is to study the perspective of the preschool teachers and their knowledge regarding bilingual and multilingual children. Their knowledge will be examined related to their language experiences. I hope to find similarities and dissimilarities in the preschool teachers? opinions concerning teaching and learning what they actually do when they are teaching.My study is based on qualitative method, based on interviews and repeated observations.
Anestesipersonalens peri-operativa omvårdnad av överviktiga och obesa barn
Children are a group of patients that require special knowledge from the anesthesia staff, both general and specific. Theoretical knowledge and practical experience is necessary to adequately care for the child as it anatomically, physiologically and mentally may differ from adult patients.A growing problem in the pediatric population is overweight and obesity. From a stagnation in the early 2000s the prevalence of overweight and obesity among children in the world are again increasing.The purpose of this study was to examine peri-operative care of overweight and obese children.Systematic searches were done in PubMed, CINAHL and Scopus. After the quality audit according to SBU, twelve articles were included for analysis.Results suggest that overweight and obese children have a higher risk of respiratory peri-operative complications. The risk of hospital admission after outpatient surgery was also greater in this group as well as higher costs for health care.Overweight and obese children are complex subjects with more frequent peri-operative risk factors than normal-weight children.
Applicerbarheten av produktanpassade supply chain-strategier inom stålindustrin : En fallstudie
AbstractThis study aims to investigate the applicability of well-recognized supply chain strategies based on product characteristics. Choosing the right supply chain strategy can be the difference between winner and loser in today?s competitive climate and science offers several recommendations as to which aspects that should be considered. Fisher (1997) and Christopher and Towill (2002) suggest that supply chain strategies should be based on what kind of product the company is handling and that, in order to know which strategy is the most appropriate, the products must be categorized. Some criteria developed for the categorization are lead time, forecast in demand and profit margin.
"Jag gjorde det dom betala för" : En narrativ berättelse om en kvinnas liv och vägen ut ur prostitution och missbruk
This study aims to find out what happens with the roles that are seemingly left behind. Are there roles that are harder or easier to exercise? Available roles with us through life and affect our future decisions or we switched completely away from them and create new roles based on the situations we find ourselves in at the moment? The aim is also to see how the relationship looks like between closed roles and new roles in life. To try to find this out, I have used the narrative method. The study is based largely on Goffman's theories of roles, behind and above the front- and back stage.
Snedställningskrafters påverkan på prefabricerade pelar-balk stommar
The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

Betjäningskostnader i olika distributionskanaler: En fallstudie av ett svenskt bokförlag
In a time of economic turmoil and financial crisis profitability matters rise higher and higher on company agendas. Many companies are pressured to find profitability to avoid layoffs or even bankruptcy. Profitability essentially depends on the margin on the product or service sold and the costs associated with selling these products or services and hence these areas are of vital importance if companies are to improve profitability. Previous research has focused, for the most part, on product profitability while customer profitability has received less attention. This study is based on a case study of a Swedish publishing house and aims to investigate how the company?s Cost-to-Serve varies between its distribution channels.
Brittiska Labour ? svikare eller frälsare? : Om ett svikt vallöfte eller en räddning av Storbritanniens inflytande i EU.
This Bachelor thesis deals with the act of the British Labour Party when they recalled a referendum promised by former Prime Minister Tony Blair. Tony Blair promised a referendum on the Constitutional Treaty, but his successor Gordon Brown later recalled it when the Lisbon Treaty succeeded the Constitutional Treaty as the legal foundation of the European Union.The main purpose of this thesis was to with help from various theorethical frameworks explain why the Labour Party decided to do this, even if this decision gave the main opposition party, the Conservative and Unionist Party (the Tories), the chance to heavily critisize the Labour Party, and picture them as traitors.The research questions were:? What are the reasons that the Labour Party went from being a Eurosceptical party, to become more pro-European?? Why did the Labour Party cancel the promised referendum on the new treaty of the European Union?Various answers were found for the first research question. Among the most important was that it was a part of the over all transition which led to the launch of New Labour.The second research question was answered with three explanatory models based on actions of the Labour Party on three arenas; the electoral arena (based on power, this model claims that the Labour Party act as they do because the know the Tories would not act differently if they were in office), the parliamentary arena (based on ideology, this model claims that Labour want the Lisbon Treaty because it has a stronger social dimension than earlier treaties) and the internal arena (based on the problem of identification, this model claims that the Labour Party identifies itself with the British government, and not just the voters, and are afraid of damaging Britain?s influence in the EU and international politics if Britain says ?no? to the Lisbon Treaty)..
