Korrelerar startlereaktion med reaktionstid?

Bilder av potentiella hot upptäcks snabbt och leder till en snabbare reaktionstid än bilder av icke-potentiella hot. Potentiella hot stjäl också fokus och kognitiva resurser, med en långsammare reaktionstid som följd. Rädsla, som kan mätas genom startlereflexen, leder till antingen ökad handlingsberedskap (snabbare reaktionstid) eller kognitiv distraktion (långsammare reaktionstid). Fem försöksdeltagare fick reagera på en visuell probe som lades ovanpå djurbilder, både potentiella hot och icke-potentiella hot i ett kombinerat reaktionstids- och startleprobeexperiment, där ljudstötar utdelades i hörlurar. Startlereaktion, hjärtfrekvens och reaktionstid mättes, varefter korrelationskoefficienter räknades ut.

"Ett förskräckligt missbruk av yttrandefriheten" : en uppsats om underförståddhet i svensk nyhetsrapportering om Lexbase

In January of 2014 a newly founded company held a press conference in central Stockholm. The purpose of the conference was to inform about Lexbase, the largest database on the Internet with legal information about the Swedish general public. The aim of this particular paper is to use news reports about Lexbase as material to identify the theses and their types presented in Swedish newspapers, and to examine the ideology constructed and presented by the theses in the said news reports. The questions asked in the paper are 1. What the distribution of different theses looks like and is there a type of thesis that more often invokes an implicit argumentation? 2.

Ett nytt pedagogiskt material! : 4DFrame, hur kan man arbeta praktiskt med det?

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.

Shamyana, the out door pleasure

The present work is a continuation of the ideas developed in previous projects during my Masters studies that explored the relation between pattern, form and space. Starting from the pattern multiplication for space construction the present project proposes textiles as an assortment of flexible expressions. The purpose of the project is to explore aesthetic and functional potential of textiles for out door temporary structures. This is to create a pattern interface which filters sunlight through a textile surface to offer instant sheltering solutions for out door activities. The project combines research and analyses of outdoor temporary structures and scope of textile in the area.

Tillämpning av GIS-analyser i MKB

The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.

Matematikdidaktik : En teoretisk studie av att lära algebra

This is a literature study of learning mathematics in general and algebra in particular. The goal is to explore and investigate the learning procedure and the difficulties pupils have with their understanding. Furthermore, to understand what qualities is requested of pupils in their effort to be successful in mathematics and algebra. I have also explored different pupil thinking styles in mathematics and what consequences that has on their learning and understanding. Moreover, I have investigated some different learning styles and how they can be addressed in teaching of mathematics in general and algebra in particular.

UNSCR 1325 i idé och praktik - en analys av säkerhetsrådsresolution 1325:s potential

I oktober år 2000 antog FN:s säkerhetsråd resolution 1325 (UNSCR 1325) som behandlar kvinnor, fred och säkerhet. Detta var första gången kvinnors status i säkerhetspolitik behandlades på högsta internationella nivå, och resolutionen är delvis en produkt av lobbyarbete gjort av kvinnors NGO:s. Denna studie ämnar undersöka vilka potential UNSCR 1325 har för uppluckrandet av ojämlika mönster i könspositioner som finns inom fältet för fred och säkerhet. Studien består av en idéanalys och en praktisk analys som görs utifrån tre dimensioner ur feministisk teori. Analysen visar att de idéer resolutionen vilar på inte utmanar de rådande snäva mönster i könspositioner som finns i dagens säkerhetspolitik och har därför heller inte potential att göra det praktiskt.

Slimmade möten, en undersökning av Leans påverkan på mötesprocesser

Lean has been studied intensely since the 1980s and it has been tested and successfully implemented in a wide variety of businesses. This thesis aims to examine the potential effects of a Lean implementation on meeting efficiency, a topic that has gotten little attention in the research community. First, a number of meeting problems are introduced, as they are perceived from the company that is the subject of the study. Second, the potential of introducing Lean in a meeting process is evaluated using the Lean Thinking principles. Third, the wastes that are generated from the meeting problems are identified.

Vintervegetation genom ljus : om hur man med belysning kan framhäva avlövad vegetation i offentlig stadsmiljö

Use of lighting is crucial to make public urban places available during dark hours. Landscape architects participate in planning of lighting, but during our education there is very little taught on the subject. Through this study we approach the subject of lighting by looking into lighting methods for urban plant materials during winter. In this thesis we look into ways to emphasize the visible characters and experiences of urban plants during winter season using light. Target audience are landscape architect students and landscape architects without knowledge of lighting. The part of the thesis that describe basic conditions for, and visual characters of plants can be useful to lighting designers without knowledge in this subject. Working methods used were the following: ? Pre-study about light and lighting techniques through literature and dialogues. ? Compiling important visual winter plant characters through photography and literature. ? Outdoor light experiments with plants.

Underlag för solcellsproducerad el i Stockholm : Potential och klimatpåverkan

The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

Mellan bildningsideal och besparingskrav : En studie av Uppsala universitetsbiblioteks styrdokument 1999-2013

The purpose of this thesis is to investigate how structural changes are depicted as well as formally brought about in the documents of rule and regulation of Uppsala University and Uppsala University Library the years 1999?2013. Beside the documents of rule and regulation, also documents that is commenting on (or in other ways relates to) these are investigated. The study is based both in organizational theory and modern rhetorical theory. The results show that the University to a certain extent gained an increased possibility to micromanage the library?s working routines during the time span covered and the study traces the consequences this had on the library organization and reactions it evoked among the leaders and representatives of the library staffThis raised a debate between representatives from the University library and its mother organization, the University, regarding at which level in the whole organization decisions regarding the library?s forms of funding and everyday praxis.

Måla med musik, komponera med färg : En retrospektiv studie av den kreativa processen, bland bild, musik och synestesi

The relationship between color and music, and their relation to the human being and our surrounding universe has been subject of studies, theories and experiments since the old ages. From the ancient China and Persia to the present times, philosophers, scientists and artists have tried to explain these connections between color and music and also tried to find answers to this ancient enigma.The invention of the color organ c. 1730, an instrument that was intended to display color in addition to the musical auditive experience, was the first attempt to materialize the practical correlation between notes and color. This correlation has its foundation in the ideas of Isaac Newton, who through his book Optics published only a few years earlier, conformed the beginning of a new art culture: ?Visual music?, in which image and sound are the fundamental elements in the creative process.The ?visual music? concept is not only grounded in the ideas of music and sound, but also in the extraordinary creative capability of certain individuals.

Situationsanpassat ledarskap för byggproduktion

A large cost at the construction sites today is the labour cost of the workers. But unfortunately the worker potential is not used to full. It is not unusual to take into a count with a work-­?place-­?additional-­?time of 50% in some cases. By increasing the workers' motivation and responsibility for their tasks may reduce the time considerably, which also increases the potential for greater gains in construction projects.By using the situational leadership may the workers level of maturity develop entirely.
