Att handla för förändring- en studie om politisk konsumtion ur sociala rörelsers perspektiv
På det individuella planet handlar politisk konsumtion till stor del om att uttrycka en etisk, politisk eller miljömässig åsikt genom att välja och välja bort varor på marknaden. Denna uppsats flyttar fokus till kollektiva aktörer och betraktar politisk konsumtion som ett verktyg. Syftet är att besvara huruvida sociala rörelser kan och faktiskt använder sig av detta. I uppsatsens teoretiska ramverk identifieras och operationaliseras sex så kallade metoder för politisk konsumtion. Vidare undersöks huruvida tre sociala rörelser med olika intresseområden använder sig av dessa.
Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future
Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient
urban biotopes which also can be used by local urban communities.
The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design
competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields.
In my proposal I applied ecological design principles on three scales:
the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged
material.
Slut eller början? - en studie av före detta soldaters reintegration i Sierra Leone
The aim of this study about post-conflict economic, social and political reintegration of ex-combatants is to understand how such a process should be prepared for in order to help as many traumatized and sometimes destructive or disabled soldiers as possible to re-establish themselves as functioning civilians as well as preparing communities for their return. In order to do this I have focused on Africa and in particular the DDR-process of post war Sierra Leone. My study concludes that the relation between ex-combatants and civilians and the prospect of a positive future are crucial to a successful reintegration process..
Hur bör det amerikanska kampanjfinansieringssystemet till val av president reformeras? Mot frihet eller rättvisa?
Denna uppsats behandlar frågan: Hur bör det amerikanska kampanjfinansieringssystemet till val av president reformeras - mot ett system som fokuserar på frihet eller ett system som fokuserar på rättvisa? Som frågeställningen vittnar om är uppsatsen skriven ur ett normativt analysperspektiv där de klassiska värdena frihet och rättvisa i kombination med insamlad data om amerikansk kampanjfinansiering mynnar ut i en analys. Två alternativa väga presenteras, antingen att släppa systemet fritt eller att öka kontrollen för att minska skillnaderna som finns. Argumentationen ger en bild av hur annorlunda systemet skulle kunna se ut givet en förändring. Resultatet påvisar att det amerikanska systemet hade gynnats av att röra sig mot en mer rättvis och kontrollerad finansieringsstruktur.
?Naturvetenskap finns ju överallt? : En kvalitativ studie av hur förskollärare på småbarnsavdelningar på Reggio Emilia inspirerade förskolor ser på arbetet med naturvetenskap
The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different stations where the children themselves have the opportunity to explore various scientific areas.
En jämförelse av hästens tidsbudget och dygnsrytm : frilevande och i stall
Today it is common to have adult horses stabled for most of the day. This limits the horses? ability to perform some of their natural behaviors such as foraging and movement. The purpose of this review was to compare the feral horses? diurnal rhythm and time budget with stabled horses.
"Storebror" kommer till stan? En diskursanalytisk studie av debatten kring kameraövervakning av "Stråket" i Malmö
Social control in different forms has existed in all known societies. This control has taken different shapes and expressions. In older smaller communities there was a collective control among the citizens. In modern societies the state is trying to control the lives of the citizens. These control mechanisms can be seen as both freedom-reducing and freedom inducing depending on which concept of freedom one upholds.
Komfortsanalys med hänsyn till vibrationer orsakade av människoaktiviteter. : Ett modernt dimensioneringsproblem för huskonstruktörer
Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

Malmö som stad, upplevelse och varumärke: En diskursanalys av en postindustriell stads framtidsvisioner
This is a discourse analysis concerning the visions for Malmö's future. Three concepts are studied to see which meaning these are given in the Malmö context. The studied concepts are ? development (utveckling), industry (näringsliv) and citizen (befolkning).The meanings of these concepts are studied against a backdrop of theories of inclusion/exclusion in general and inclusion/exclusion in the city more specific. Michael Foucault´s notion of a discourse which stigmatizes those not following a behaviour which is defined as being right and normal is central to this.
Acehkonflikten - en analys med identiteten i fokus
A violent conflict emerged in the Indonesian province of Aceh in 1976, with the rebels of the Free Aceh Movement, GAM, on one side, and the Indonesian government on the other. GAM demanded Aceh to become independent, but the Indonesian government did not accept their nationalistic claims. The conflict therefore lasted for almost thirty years, and many civilians were killed during this period. This essay deals with this particular conflict; its causes and its solution. In the centre of the analysis we find theidentity of the Acehnese people, and the way in which this identity has beenconstructed and re-constructed throughout the history.
Lycka: nyckeln till en önskvärd socialpolitik - en begreppsanalys
This essay deals with the same task that utilitarians have tried to solve for a long time, what is happiness? In the eighteenth-century utilitarians suggested that happiness should be the base for social political decisions. But the lack of definition disposed so that GDP became the measurement of happiness, which proved to be wrong when the unhappiness continued to increase. More than two hundred years later scientists came up with a new definition of happiness and new ways to measure it. And during the last decade economists have taken the discussion to a higher level.So once again we?re dealing with the same old issue, if happiness ought to be the base of social political decisions.
Barnröstens förändring under dagen i en anpassad röstinspelning och spontantal : En experimentell studie av perceptuella och akustiska parametrar
A controlled recording in a studio is the basis of all voice treatment. However, this controlled way of recording voice patients' voices can be questioned. The voice use may be different in a natural environment. In children noise related voice problems are investigated in a study about voice and its development (BUG ? Child voice and noise).
Lätt som en plätt? Problematik kring samordningen inom den svenska förvaltningen
Hur staten organiserar sin förvaltning, i form av specialisering och samordning av verksamheten, har betydelse för hur väl uppdraget att implementera den politiska viljan genomförs. Många menar att betoningen på samordning idag ökat efter flera år av specialisering som dominerande organisationsform. Vi har därför valt att undersöka begreppet samordning och dess tillhörande problematik för att se hur, när och var samordning är önskvärt inom statlig förvaltning och vilka problem som kan uppstå. Då samordning är en flertydig term som kan vara svårförstådd, avser uppsatsen också konkretisera begreppet och dess övergripande problematik. Genom intervjuer på Migrationsverket ges praktiska exempel utifrån en svensk kontext.
Användning av geografiskt informationssystem (GIS) vid studier av nötkreatur i landskapet - en pilotstudie :
The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.
