Studie om individers kontrastkänslighet och preferenser för horisontell och vertikal belysningsstyrka

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

The effects of two light programs on sleep in dairy cattle

Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

Språkbad - en insats för framtiden? : En jämförande analys mellan språkbadselever och enspråkiga elever

This thesis is based on thirteen qualitative interviews with civil servants and politicians. The purpose of the study is to research these informants? attitudes towards integration and their reflections about immigrants? lower chances in an ethnically segregated housing and labour market. The theoretical frame of references is based on social constructionism and focuses on including and excluding power structures. The empirical material provides both structural and cultural explanations to immigrants? problems as regards inclusion in Swedish society.

Alternatives for another world?: En kritisk analys av Occupy Wall Street-rörelsens idéer för strukturell förändring

In the wake of the latest financial crisis, a group of individuals launched the Occupy WallStreet movement. It wanted to change the structures that economic and political life arefounded upon. They believe that the established structures are unfair and exploit the majorityof the population. Researchers critisised the movement saying it was ambiguous because itcould not produce any realistic ideas for change, while others thought that was a success forthe movement.Therefore, the aim of this Bachelor Thesis is to examine the different ideas articulatedby the Occupy movement and present them systematically. Through an inductive qualitativetext analysis six different themes are identified regarding how the movement wants to changethe structures in society to make them fair.

Skönlitteratur som kulturell bro: om utländsk skönlitteraturs tillgänglighet på svenska

This study is an attempt to shed light on the importance of fiction as a bridge between different cultures and traditions. The objective of this essay is threefold. First it explores the potentiality of fiction as a communication channel between different cultures, societies and social groups. Secondly, it studies the availability of foreign fiction in Swedish language. And thirdly it tries to approach and analyze the structures and mechanisms behind that availability.

Det talas om utbrändhet : vilken roll spelar maktstrukturen

In this paper we investigate whether power structures in organizations have an influence in the process that leads to burnout. We analyze if these power structures affect the individual?s health condition toward burnout in a way that leads to disability and subsequent absence from work. In the study, six persons who all have been unable to work due to burnout have been studied through qualitative, semi-structured interviews. The material have been coded with three different themes; leadership and hierarchy, responsibility and delegation of responsibility and performance and loyalty.

Högeffektslysdioder. Möjligheter och förutsättningar för högeffektslysdioder som belysningskälla - ett demonstrationsbygge

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

The effect of a lowered light intensity at night on cow traffic and milk yield in automatic milking systems

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

Sveriges och Europeiska Unionens biståndspolitik : En jämförande idéanalys ur ett postkolonialt perspektiv

The main aim of this study is to examine the development policies of Sweden and the European Union from a postcolonial perspective. Sweden and the European Union are increasingly coming to be viewed as normative powers rather than military powers. So how does the colonial past of the western societies affect the policies of today? Are there any signs of the power structures of the past, and if so, how are these power structures manifested in the development policies of today? Since both Sweden and the European Union have come to be viewed as normative powers they are compared with each other to highlight their similarities and differences. The results of the study shows that both Sweden and the European Union can be seen as carriers of western values and interests.

Aktörer och strukturer inom svenska statsvetenskap : En granskning av tre statsvetenskapliga bidrag till aktör - strukturdebatten

The purpose of this essay is to critically review three different contributions to the agency ? structure debate from a political science perspective. My opinon is that the agency ? structure debate is one of the main problems within the social science. The theories which I will examine are Lennart Berntsons theory from 1974, Lennart Lundquists from 1984 and Walter Carlsnaes from 1992.

Kromförångning i fastoxidbränsleceller

This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

En diskursreglerad v?rld: Makt, kunskap och agens i Mark Lawrence? The Book That Wouldn?t Burn

Historically the library has owned more than silent, book-filled halls; it has been a center for learning and ideas, a source of both freedom and oppression, in other words, a medium for knowledge, truth, and power. Cultures have been divided into powerful and powerless through access to the library's content; those who have - and those who do not have - access to information determine which voices are heard and which are ignored, thus determining the outcome of the future. This thesis investigates how The Book That Wouldn't Burn by Mark Lawrence portrays the relationship between knowledge and power using Michel Foucault's discourse theory. More specifically, how this relationship is manifested through the structures and norms of society, and how the library as a place and institution serves as the means by which this relationship plays out. An established classic like Fahrenheit 451 by Ray Bradbury is placed as a contrasting reference point to help deepen its thematic message of information control and cencurship. Furthermore, the agency of one of the main characters is also examined in the light of Anthony Giddens' stratification model, as an actor with the potential to move beyond the confines of the power structure. The analysis demonstrate how knowledge, truth, and power remain continuously thematically relevant within literature, and how the reality of our time may be better understood through literary contributions.

Centraliserad decentralisering? En studie av Marrakechprocessen och dess relation till global governance

The current debate regarding organizational strategies for sustainabledevelopment is influenced by the theory of global governance. Decentralizedstructures of the global society are taken to use in the realization of a sustainabledevelopment. New roles of transnational networks and partnerships raisesquestions of the ability of global governance to co-ordinate and implement longtermsolutions without assistance from centralized and hierarchic structures basedon government. The aim for this thesis is to illustrate the current conditions forwell-functioning networks of sustainable development and examine therelationship between global governance and government. Issues of participation,decision making and compliance are examined by a case study of the Marrakechprocess, a global process to support the implementation of sustainableconsumption and production.
