Varför upplevs vissa grönområden otryggare än andra?
Idag pratas det väldigt mycket om trygghet. Överallt ska det vara tryggt. Vi
vill vara anonyma, men vi vill alltid att någon ska se oss för att vi ska känna
oss trygga. Därför ökar beståndet av t ex. övervakningskameror.
Vi och våra andra Om konstruktionen av de andra i svenska läromedel. En diskursanalys av fem samhällskunskapsböcker för högstadiet.
The purpose of this study is to examine to what extent the senior level Swedish school can be viewed as supporting, or counteracting, a colonial discourse that legitimizes global and national injustices. The study is executed through a discourse analysis of five textbooks in social science for senior level Swedish schools.Using elements from Foucault and Edward Said a theoretical framework is constructed, in which a colonial discourse is perceived as structured around four clusters of ideas, namely (i) the use of dichotomies, (ii) the concept of progress and civilization, (iii) the construction of -we- as synonymous with (ii), and (iv) the construction of -the others- as the opposite of (ii) and, therefore, the opposite of -us-.The results show that a colonial discourse is still highly present in the textbooks, in that the texts are structured around dichotomies such as tradition/modernity and democracy/dictatorship. Sweden and the Western world are perceived as closely associated with democracy, freedom, and modernity, whereas -the others- of the world are being associated with e.g. poverty, conflict, tradition, and ignorance. -The others- within Sweden, i.e.
Kommun 2.0 : En studie av Uppsala kommun och Tierps kommuns användande av sociala medier
Title: Brand evolving in identity shaping TV commercial ? a quantitative study of Gevalias commercial movies over time. (Varumärkesutveckling i identitetsskapande tv-reklam ? en kvantitativ studie av Gevalias reklamfilmer över tid) Number of pages: 35 Author: Julia Garellick Lindborg Tutor: Anne-Marie Morhed Course: Media and Communications studies C Period: Autumn of 2010 University: Division of Media and Communication, Department of Information Science, Uppsala University Purpose: The purpose of the study has been to investigate in what ways the concept of success is constructed in Gevalia?s TV commercials with the theme ?unexpected visit?. Eight identity evolving variables have been chosen to measure variations in the pattern of the unexpected visit in order to understand the essence of time.
Hur påverkar en ökad andel solceller Umeå Energis elnät? : ? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar
A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.
Förändring av cyberpunkgenrens stereotypiska nattema
Cyberpunkgenren definieras som en genre med en uttalad mörk framtidsbild med dystopiska inslag där bioteknik och artificiell intelligens är återkommande inslag och där majoriteten av verken som berör genren utspelar sig på natten. Syftet med denna studie har varit att undersöka om förändringar av det stereotypiska nattelementet som cyberpunkgenren förknippas med anses vara genrebrytande. Förändringen som gjordes var att nattbelysningen byttes ut mot dagsbelysning i en cyberpunkmiljö. För att genomföra detta skapades en stereotypisk cyberpunkmiljö med hjälp av datorgrafik som sedan presenterades i två versioner, en i nattbelysning och en i dagsbelysning. Bilderna visades därefter upp för en informantgrupp som var kunnig inom science fiction och cyberpunkgenren och som därefter fick besvara ett antal frågor under semistrukturerade kvalitativa intervjuer..
Miljöinformation från teori till praktik.
The purpose of this paper is to investigate the process of transferring information from science to "the field" of environmental protection in Sweden. I have studied four Swedish environmental organizations, Greenpeace Nordic, WWF Sweden, the Swedish Society for Nature Conservation and Friends of the Earth Sweden to see how they search/get information. I have also studied the Swedish Environmental Protection Agency and its role as sender of information, since it is the authority which is responsible for environmental information in Sweden. I have used information and communication theories as a help to analyse my results. While working on this paper I realized that my methods were not the best.
Vad är Cloud Computing? : En kvalitativ studie ur ett företagsperspektiv
Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.
Mätningar av statiska och dynamiska egenskaper för bakaxel.
To design new and high tech products the engineers rely more and more on computer based simulations to investigate the properties and behavior for a component or system.To verify these computer based simulations the dynamic properties for the components of the drivetrain needs to be verified. Therefore measurements of the stiffness and vibrations for the rear axle has been performed. This report show how the measurements has been implemented and evaluated, along with some interesting results for the rear axles properties.The static stiffness for the drive shaft along with the axle-gear has been determined. It is found that the stiffness for the whole rear axle is near the stiffness for the drive shaft, which means that the drive shaft becomes the dominant component of the system and affects the rear axle stiffness the most. The measured stiffness of the driveshaft is close to its theoretical stiffness.The stiffness for solely the hypoid-gear have been calculated using the stiffness for the rear axle and driveshaft, and thus has a range for the stiffness of the hypoid gear been determined.The backlash for the whole rear axle and for some individual components has been determined, where the backlash between pinion and crown-wheel has negligible impact on the total backlash.Measurements of the crown-wheel and pinion movements have been conducted, where the direction of movement is consistent with the theoretical direction of the forces.The vibration measurements show that the vibrations are more severe at certain rotational speeds.
Lärares syn på arbetet med partikelbegrepp i no-undervisningen
In this study we have interviewed eight teachers about when and how particle concepts should be taught. All of the surveyed teachers argue for an early introduction. This view is also consistent with the scientists on when the particle concepts should be introduced. By an early introduction teachers and scientists consider the age between 6-12 years old. A majority of the scientists and the surveyed teachers use concept of change as a entery point to talk about particle ideas.
Sjuksköterskors uppfattning av elektronisk dokumentation avseende tidsåtgång, teknik och vårdkvalitet
Documentation in electronic journals is perceived as time consuming and sometimes technically difficult to handle, but also leads to an improved quality of care. Objective: The purpose of this study was to investigate nurses' perceptions of documentation with a focus on timing, technique and quality of care and whether any differences in these perceptions were dependent on age. Method: Quantitative descriptive cross-sectional study in the survey form, 28 nurses at a university hospital in central Sweden participated in the study. Regression analysis was performed with Spearman's rank correlation coefficient. Results: Electronic documentation takes 30 to 60 minutes for most nurses and half of them considered it a reasonable time.
Den slutna cirkeln, eller varför mångfalden inte når till toppen
Sweden is usually seen as a role model when it comes to integration and diversity, but at the top of the pyramid there is little ethnical diversity to be found. This paper investigates how existing economical and sociological theory explain the lack of swedes with foreign background in leading positions in large Swedish companies. Our findings show that none of the theories applied in this paper can explain the phenomenon in isolation. Thus it is not only taken for granted norms, contacts in one's network or cost minimizing under asymmetric information that lie behind the phenomenon, but an interaction of these aspects. Conflicting demands lead the recruiters to separate talk from decision, the search frame is narrow and no or small efforts are made to increase the diversity.
Synen på det egna ledarskapet : En jämförelse mellan ledare inom skola och vård
AbstractThis essay contains a comparison between principals and supervisors within the Health-care and is focused on their view regarding their own leadership. It contains a comparison between their respective models for leadership and how to evolve as a leader within these two organizations.The study is carried out as in dept interviews with four principals and four supervisors.The results show that the principals have a sufficient education and a broad network, but they need the opportunity to a personal development within their leadership. On the other hand, within the Health-care, the supervisors stand on a good base of education where focus lies on the personal development within the leadership. However, they need more opportunities to build up their networks.The conclusion that can be drawn is that these two organisations would gain on learning from each other, in order to establish as good conditions as possible to improve the leaderships within their own organization..
Papper åt alla! En diskussion om post- och transnationalitet i dialog med den spanska sociala rörelsen för papperslösa migranters rättigheter.
The aim of this paper is to expand the debate on globalization and its consequences from a theoretical perspective emphasizing social processes of exclusion and inclusion. I explore these social processes in dialogue with the Spanish social movement for the rights of irregular immigrants. The paper also aims to explore new forms of resistance in the context of globalization."The declinist thesis" argues that globalization has lead to a declining importance of the nation-state and the national citizenship as guarantees of rights. "The anti-declinist thesis" oppose to this picture arguing that rights still depend on national policies. I also discuss the functions of exclusion and inclusion inherited in the concepts of citizenship and nation-state.I outline the historical and political context of the movement and explore the ideas and organizational dimensions of the movement's "knowledge praxis".I conclude that national citizenship - in a broader sense as a description of the relationship between the individual and the state - seems to play a crucial role in the life situation and the possibilities of irregular migrants to organize and protest.
Att välja avsked - Arbetsgivarnas valmöjligheter i uppsägningssituationer
Under de senaste åren har det blivit vanligare att arbetsgivare väljer att avskeda en arbetstagare istället för att säga upp denne. En skillnad mellan dessa två åtgärder är att vid ett avsked avslutas anställningen omgående medan en uppsägning följs av en uppsägningstid. Den skillnad som är av största betydelse för arbetsgivarens val är att om arbetstagaren yrkar att uppsägningen ska ogiltigförklaras kvarstår anställningen tills tvisten är löst. Detta gäller inte vid avsked, där skiljs arbetstagaren från anställningen även om denne yrkar att avskedandet ska ogiltigförklaras. Anställningsskyddslagen tillsammans med skadeståndspraxis ger en arbetsgivare som väljer avsked istället för uppsägning möjligheten till en ekonomisk besparing..
I inneslutande VR : En kvalitativ undersökning om användares närvarokänsla första gången de befinner sig i en virtuell miljö.
Syftet med denna uppsats är att göra en undersökning om vilka faktorer som påverkar användares närvarokänsla första gången de använder sig av en inneslutande virtuell miljö. De inneslutande VR tekniker vi har valt att fokusera på är Computer Automatic Virtual Environment (Cave) och Head Mounted Display (HMD).Forskaren Carrie Heeter beskriver tre typer av närvaro och forskarna Wallace Sadowski och Kay Stanney räknar upp faktorer som de påstår påverkar användarens närvarokänsla.Vår frågeställning är vilka likheter eller skillnader det finns mellan våra testpersoners svar och Sadowski och Stanneys faktorer. Vi intervjuade och genomförde ett test med tre testpersoner i en Computer Automatic Virtual Environment baserat på två program. Vi valde även att intervjua två experter om vilka faktorer de ansåg påverkade deras närvarokänsla första gången de använde sig av en HMD.Första programmet som testpersonerna fick pröva på var Cuevadefuego som bestod av tredimensionella bilder till skillnad från det andra programmet, Crayoland, som bestod av tvådimensionella bilder. Intervjufrågorna till testpersonerna och experterna baserades på frågor som handlade om experternas och testpersonernas reaktioner och intryck relaterat till deras närvarokänsla och vad de trodde det var som påverkade deras närvarokänsla.Resultatet av intervjuerna och testet är att det finns likheter mellan de faktorer som testpersonerna anser påverkar deras närvarokänsla och med Sadowski och Stanneys faktorer men inga direkta skillnader..
