VEM ST?DJER BIST?NDET? En kvantitativ studie om vilka faktorer som p?verkar attityden gentemot EU:s internationella bist?nd
The discussion regarding international aid tends to be highly debated for long periods of time.
Some individuals are very positive towards aid and some individuals are less positive towards
aid. This study aims to broaden the understanding of the aspects behind that. The previous
research tends to focus on aid allocation within the EU, or which macro factors could influence
which donor countries give to which recipient countries. This study aims to add to the research
with which aspects at the individual level can influence the individual's attitude towards
international aid from the EU.
The legacy of the mill : a metal polluted forest soil in Gusum
Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.
Analys och utveckling av boggi till ramstyrd dumper
Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.
Upplevelser av osäkerhet: En kvalitativ studie av globaliseringens effekter för ungas etablering på arbetsmarknad och familjebildning
Globalization is described as processes of economic, social and political character and a tendency in the field has been to study these aspects of the phenomenon separately. Another common feature of previous studies is to relate to the field at a high abstraction level and talk about the effects and changes in general terms. Such studies of quantitative and statistical nature in which people are constituted as homogeneous groups hides the fact that the relationship between social attributes and context creates unique positions where the effects of globalization are diverse (Sprague, 2005, pp. 16 - 18). The purpose of this bachelor thesis is therefore to break with this entrance to the field and instead focus on a micro level perspective.By conducting a qualitative interview study guided by the globalization theory of the Globalife research team, which shows how structures at the macro level can be understood to affect the micro level, the aim is to reveal potential knowledge gaps within the field.
Regionalism som motstånd : Två latinamerikanska staters motiv att ingå i integrationsprojektet ALBA
The formation of sovereign states in regional blocks has become an essential feature in the world system. Therefore, the purpose of this paper is to investigate which motives and driving forces that affect the creation of projects of regional integration outside Europe and the Western World. By choosing the Latin American project of integration ALBA (the Bolivarian Alliance of the Americas) as a case of regional integration outside Europe and the Western World, the study investigates the motives expressed by the most prominent actors of the project, Venezuela and Cuba. ALBA is chosen as a representative and a unique case and through the consumption of the gramscian and the realist approaches, the essay defines two motives that affect the creation of projects of regional integration. As a way of investigating the actors? motives, the paper studies political statements, especially those of the Venezuelan president Hugo Chávez, and official positions expressed in central documents and declarations.
Slutfasstyrning av robot - en jämförelse mellan LQ och MPC
Arbetet har utförts på Saab Bofors Dynamics i Karlskoga och dess syfte var att undersöka om det är möjligt att använda modellbaserad prediktionsreglering, MPC, vid slutfasstyrning av en viss typ av robot. Som referensram används linjärkvadratisk reglering, LQ, eftersom denna reglermetod har undersökts tidigare och visat sig fungera bra vid slutfasstyrning, dock för en annan typ av robot. Anledningen till att man vill undersöka om det är möjligt att använda MPC är att styrlagen enkelt tar hand om begränsningar på systemet på ett direkt och intuitivt sätt.Styrlagarnas uppgift är att styra en robot i dess slutfas då det finns krav och önskemål på roboten som bör vara uppfyllda. Till exempel finns det begränsningar på styrsignalen samt önskemål om att träff ska ske i en viss träffpunkt och även med en viss träffvinkel. För att utvärdera resultaten undersöks och jämförs de två styrlagarnas prestanda och robusthet.För att kunna utvärdera styrlagarnas egenskaper och jämföra dem implementeras de båda i en befintlig detaljerad simuleringsmiljö, som har utvecklats på Saab Bofors Dynamics i Karlskoga.De prestanda och robusthetstester som har utförts uppvisar små skillnader på de två styrlagarna och slutsatsen blir därmed att det är möjligt att använda modellbaserad prediktionsreglering vid slutfasstyrning av en viss typ av robot eftersom det sedan tidigare är känt att linjärkvadratisk reglering är en bra styrlag att använda.

"The Machine Made Me Do It!" : An Exploration of Ascribing Agency and Responsibility to Decision Support Systems
Are agency and responsibility solely ascribable to humans? The advent of artificial intelligence (AI), including the development of so-called ?affective computing,? appears to be chipping away at the traditional building blocks of moral agency and responsibility. Spurred by the realization that fully autonomous, self-aware, even rational and emotionally-intelligent computer systems may emerge in the future, professionals in engineering and computer science have historically been the most vocal to warn of the ways in which such systems may alter our understanding of computer ethics. Despite the increasing attention of many philosophers and ethicists to the development of AI, there continues to exist a fair amount of conceptual muddiness on the conditions for assigning agency and responsibility to such systems, from both an ethical and a legal perspective. Moral and legal philosophies may overlap to a high degree, but are neither interchangeable nor identical.
Retention av tungmetaller i en anlagd våtmark : studier av Vattenparken i Enköpings kommun
The aim of this study was to examine the amounts of heavy metals in the sediment of a wetland constructed for stormwater treatment. The wetland is called Vattenparken and is located in the city of Enköping. The heavy metals which were analysed were Pb, Cd, Ni, Zn, Cu, Cr and Hg. The total metal concentrations were determined using HNO3 chemical extraction. From 8 sampling sites 5 sediment cores were taken.
Förnybar energi ur ett kvinnligt och manligt perspektiv : En attitydundersökning med avseende på att kartlägga hur synen på fönybar energi påverkas av om individen är kvinna eller man
Abstract The extraction and usage of energy give rise to immense environmental problems which helps to accelerate climate change. Energy is an important resource for the community and there are a variety of different types of energy sources available, that are either classified as renewable or non-renewable energy sources. The usage of renewable energy sources cause less environmental impact than the usage of non-renewable energy, which in turn means that the energy?s strain on the environment is strongly affected by the type of energy source used.The aim of the study is to describe to what extent attitudes towards renewable energy are affected by whether the individual is male or female, by examining the hypothesis regarding how women have a closer connection to nature and to a larger extent shows on an pro-environmentally friendly behavior than men, and if it also can be detected on issues related to renewable energy and thus imply that women have a friendlier approach towards renewable energy than men. A number of ecofeminist believe that women have a stronger bond with the nature through her embodiment as a woman and by her maternal role, which according to previous research also leads to the fact that women shows on a more extensive environmental behavior.Through a qualitative research method in the form of semi-structured interviews has three female and three male respondents been asked questions with regards to the environment, individual responsibility and energy.
Identifiering av röjningsbestånd med hjälp av flygburen laserskanning
Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.
Modeller för utvärdering av set-up för återvinning av lastlister inom IKEA
Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered.
Religionsundervisning : - Genom vilka pedagogiska metoder
AbstractMy feature career as a teacher, for the early years of compulsory school, makes it interesting to finding out of how teaching religion can be donned. I am interested in what methods can be used for teaching religion That?s why my purpose aims to find out how five different teachers, of the early ages, works and what methods they use while teaching religion. My issue for this composition is: what methods, or to a point - methods supported by different teaching models, can be used for studying religion in compulsory school? Empirical and specialized literature points in the direction fore methods like storytelling, load reading, drama, group works, independent searching of information, working books and so on.
Kina i Afrika : En studie av Kinas afrikapolicy
Since the beginning of the new millennium, China has opened itself to the outside world and in an enormous pace increased its contacts and relationships with other countries. The trigger to these dramatic changes of economic and foreign policies is the insight that China can no longer sustain its rapid economic growth, largely based on industrial production, on energy and raw materials from China alone.Good relations with African countries have been of highest priority in China?s strategy of ?Going global?. The new African policy is based on the two principles of mutual benefit and non-interference in internal affairs ? as opposite to the West?s strategy of structural adjustment programmes (SAP), which include massive interference in internal affairs.
Kemisk kommunikation hos häst
Feromoner är substanser som används vid kemisk kommunikation mellan individer av samma art. Hos häst har ännu inga feromoner identifierats men studier gjorda i Litauen tyder på att kresoler, ämnen som bildas i tarmen vid nedbrytning av bland annat aminosyror och som utsöndras via urin och avföring, kan ha feromon effekt hos häst.Syftet med detta examensarbete var att undersöka förekomsten av kresoler och andra substanser i urin och brunstsekret från ston i östrus med hänsyn till variation mellan dagar i brunst och mellan provmaterial.Prover samlades in från 8 ston under 10 brunster och vid tre tillfällen från ston i diöstrus. Uppsamling av flyktiga substanser från urin- och sekretproverna gjordes med ?Solid Phase Micro Extraction? (SPME). För separering och identifiering av substanserna användes gaskromatografi och masspektrometri.
