Faktoranalys av EU: s strukturella indikatorer

This paper describes a factor analysis applied at the data of the European Union structural indicators. These are the official indicators for wealth and economic development in the European Union with main use to evaluate the outcomes of the year 2000 Lisbon goals for making the European Union the world?s strongest economy by 2010. The purpose of the data is to serve for comparing and ?learning by doing?-policies, but have, due to size and format, so far been hard to use for a good compare between member countries.

Kvalitetssäkring av stordimensionella gjutgods : Produktion och kontroll av formgjutna komponenter

AbstractA continuous improvement of products and production is an important goal for a modern industrial company. A small engineering group located in Sweden came in touch with the authors of this report during the spring semester of 2014. The aim of this report is, as part of the group´s ambition of improvement, to analyse ways in which the quality of component casted parts can be verified. Non-destructive testing (NDT), and methods to use it for quality control, is the main focus of this report. However, fields such as material standards, component casting and quality engineering are analysed as well.

Vem vill inte vara med de stora? En revidering av Brubakers teori behövs.

This paper has its aim to investigate in which way the theory about the dynamic of the triadic nexus, presented by Brubaker, needs to be revised. In the first place this theory is presented and after then applied on the triad formed by: the Hungarian national minority in Transylvania, Romania and Hungary. Through the empirical evidences, that are presented here by following up the political relations and its dynamics over time between the three fields, is shown that the theory is usable for the case in question. Further as we approach the more actual development of the political life in the triad appears a need to deal with one more field which would be for example the NATO or/and EU.This means that Brubakers theory has to be revised so it would take in account a forth field and that of an international organization/institution. The arguments for this needed change is put forth through empirical evidences on the political relations that the two states has with NATO or/and EU and the huge influence these have on the states..

Prefabricerade väggelement av hampabetong

Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.

Diversitet hos jordlöpare (Col: Carabidae) i hävdade strandnära gräsmarker :

Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands. The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow. The species composition was analysed by ordination analyses, i.e. DCA and CCA.

Designerrollen i en webbdesignprocess

This study investigates if, and in that case, how design theory is applied in practice in the web development field. Prior research has focused on methods used in the web development field. We wanted to study the designers role in a web design process by comparing existing designer roles with design theory literature. We did qualitative interviews with two practitioners at two different communication agencies in northern Sweden. Based on our qualitative data and literature review we have concluded that a designer has to devote a lot of energy on requirements engineering in order to develop a clear understanding of the design situation..

"The Never Ending Story" : Sårbarhet och kamp för överlevnad i Olofströms kommun

The world around us is shrinking and globalization and capitalism are processes affecting the world. Global trends, like outsourcing and relocation of firms to low-cost countries, have become more common. This creates a huge vulnerability in the municipalities that today are concentrated around a single large company. One of these is Olofström which today is one of the most vulnerable municipalities in Sweden and whose survival today lies in the hand of the company ?Volvo Cars Corporation?.

Automatiserad Verifiering av Grafiska Ritare och Tranformationsutvinning

En grafisk ritare i flygande system måste under dess utveckling verifieras för att bekräfta att den fungerar. Då bilderna som ritas inte behöver vara identiska mot referensbilder genererade av en fungerande ritare så ställer det krav på verifieringsprocessen att kunna acceptera en viss grad av "fel". Att automatisera den processen är i högsta grad intressant för att minska kostnaden. Uppsatsen presenterar en samling lösningar på delproblem som kan uppstå, däribland ett sätt att utvinna eventuell transformation mellan två bilder..

Vem hålls ansvarig? : En studie av de förändrade förutsättningarna för ansvarsutkrävande med avseende på svensk krigsmaterielexport

This thesis explores the changing prerequisites for accountability in terms of Swedish arms export. The study aims to uncover what has happened with the conditions for accountability in Sweden since the responsibility for export control was transferred from the government to the public administration. By investigating how the term ?accountability? has been used in the literature of democratic theory, an abstract ideal model is being created.  Comparing the changed structural arrangements, with each other and the ideal model, it is concluded that the prerequisites for accountability now seems to be in a worse state than they were before..

Socialtjänstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsätts för våld eller sexuella övergrepp i hemmet.

The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.

Nyutveckling av sjunkspärr

We got in contact with Marco AB, who we?ve had contact with before concerning earlier projects, to find out if they were interested in arranging a larger project for our last class (Examensarbete 15hp). They were very positive to this proposition, and soon they offered us a project regarding reconstruction of their current mechanical device that absorbs all the force from the lift itself when it is at a predefined level (sv. sjunkspärr). The current solution does fulfill the requirements that are given, however it is not a solution that gives a high level of satisfactory.

Ekonomistyrning inom äldreomsorgen, Intraprenad eller entreprenad - är det någon skillnad

In recent years the elderly care in Sweden has gone through several structural changes with the main purpose of delivering a more efficient service. The aim of this study is to compare the management control system in a privately and a publicly managed elderly home. A qualitative study was conducted which included interviews, observations of meetings and reviews of relevant documents. To be able to identify possible differences the framework of Hood consisting of seven dimensions was used. An analysis of the selected dimensions showed that the differences in management control were minimal and Brunsson's theory of politicization and 'company-ization' were used to explain why..

Industriell produktion av loggia - en studie om loggiarum som alternativ till inglasad balkong

AbstractIntense competition in the building industry has forced building companies to develop highly efficient and optimised building solutions. This project, with a loggia that works both as an extended living room and a glazed balcony offers a highly economic viable alternative to standard balconies. This alternative is likely to attract build master since the area of the loggia will be part of the apartment area, i.e. included in the area for rent..
