Information technology development has in recent decades had a major impact on retailing.Discount supermarket chains began to offer customers the possibility to shop without therequirement to do this over the counter, instead the customer could help themselves buyingthe products they wanted. Retailing today has an even greater focus on the self service in thesupermarkets, recently many retailing chains has introduced self-checkout systems toincrease the profits and reduce staffing requirements. In the 1960?s the start for today's ecommercewas founded, however the development took off 30 years later in the beginning of1990. During the first years of 2000 the consumption on the Internet increased rapidly.
Om konstruktionen av vetenskap i kriminalserier på TV : En kritisk diskursanalys av CSI och Bones
AbstractTitle: The Construction of Science in Television Crime Shows ? a Critical Discourse Analysis of CSI and Bones (Om konstruktionen av vetenskap i kriminalserier på TV ? en kritisk diskursanalys av CSI och Bones).Number of pages: 45 (50 including enclosures)Author: Lovisa SandbergTutor: Amelie HössjerCourse: Media and Communications Studies DPeriod: Spring 2006University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The aim was to explore the construction of science in the television crime shows CSI and Bones.Material/Method: The method used is critical discourse analysis based on the thoughts of Norman Fairclough. The analysis includes three episodes of CSI and three episodes of Bones,broadcast from between the 10th and 25th of April, in 2006 on Swedish television.Main results: The scientists in CSI and Bones are constructed as rational and calm; they are mainly concerned with finding the truth. On the surface, the truth is objective and reachable, although, in these TV-shows all observations are theory laden.Keywords: CSI, Bones, crime shows, television, science, discourse analysis..
Ordets blomma kommer inte att dö : att förändra världar genom globala nätverk
Social movements have long been valuable components of the struggle for a world with true justice. Along with the changing and modernization of society these movements also change, both in their actions as well as in the goals they want to accomplish. Technology is taking a greater part in many aspects of social life, creating new dimensions but also new social divides. This thesis examines how new social movements make themselves visible and affect the world around them through different kinds of networks. For the purpose of this study, we have chosen to study two social movements; the Zapatistas in Mexico, who have become known worldwide for carrying out the first informational revolution, and MoveOn.org, an American grassroots organization that struggles for increased democracy in the US.
"Det är roligt!" : En studie om hur pedagoger använder estetiska lärprocesser i arbetet med naturvetenskap i förskolan
The purpose of this thesis is to investigate how teachers perceive that they work with science in preschool through aesthetic learning processes as tools both in the indoor and outdoor environment and make visible what the educators' underlying beliefs are that affect how they perceive aesthetic learning processes as tools used to deepen children's understanding of different scientific phenomena.This is an interview study using the phenomenographic approach as a means and method to make visible and report on teachers' views on how aesthetic learning processes can be used to extend preschool children's learning about science. The results are analyzed and discussed based on John Dewey's theoretical ideas about children's learning, aesthetics and science.The study clearly shows that teachers' views on aesthetic learning processes and how they can be used in the work whit science is very divided and in some cases unreflective. The most striking results are that teachers often are unaware that they make use of aesthetic learning processes because they have a more limited view of what it is than we have in the paper. All informants have science as a core subject. Their focus of the activity is located at the showing and visualizeing of scientific phenomena and some of them express that they submit the aesthetic learning processes to their colleagues or that they collaborate with someone who has training in some art form.
E-BUSINESS, WHAT IS IT GOOD FOR: AN EXPLANATORY STUDY OF FIVE COMPANIES? E-BUSINESS SOLUTIONS
The notion of firms interacting with technology is not new; these types of systems were already in place in the mid eighties. E-business users worked with connections between their inbound logistics and procurement systems, and suppliers? order-entry systems. When these connections were described for the first time the vertical links between two, or more, value chains in a value system received more attention in firm strategy. The design of the linkages in the value system was said to be a product of the need for coordination and relative bargaining power.
Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med ånga
This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..
Katalogisering och presentation av film på bibliotek
The aim of this thesis is to discuss selected parts of cataloguing both from a practical and a theoretical viewpoint. It presents the basic grounds for cataloguing of printed as well as non-printed materials. The focus lies on the main entry heading and its author/title problem concerning film. The thesis theoretical part consists of an analysis of central documents dealing with the author concept from both a library- and information science perspective and a film science perspective. The practical part consists of interviews from two Swedish public libraries, which have different approaches on presenting films.
Universeum är mer än ett komplement till den vanliga undervisningen
Science center har visat sig vara en utmärkt plats för undervisning. Detta är en studie av på vilket sätt ett skolbesök på ett science center kan bidra till att målen för år 9 uppnås och om ett besök på ett science center kan utgöra ett komplement till den vanliga skolundervisningen. Särskilt studeras ämnesområdet astronomi och kosmologi (universum och vårt solsystem) i ämnet fysik. Undersökningen är gjord på Universeum i Göteborg. Metoden i undersökningen är intervjuer och observationer.
Artbrott -en institutionell bastard i gränsskiktet mellan statsvetenskap och juridik?
This paper deals with a partly new development in the Swedish law system, somewhere in the boundary between political science and jurisprudence. A new instrument -artbrott- has successively become more popular among lawyers and politicians. The new instrument -here translated to classified crimes- signifies that the perpetrator is sentenced to prison even though the seriousness of the crime committed is not in itself serious enough for such a consequence. The reason for this policy stance is to create a prevention against crime of that specific character among the public. The use of this instrument has grown considerably both concerning types of crimes as well as in application.
Samband mellan laserdata och fältdata
To make it easier for forestry planning the forest owners needs data which describe characteristics of the forest. Such data you usually get from some type of inventory. A relatively new technology which probably is getting more important in the future, is laser scanning because of lower costs. But because the laser technology is relatively new you need to compare it with conventional inventory technologies to get better understanding of the possibilities the laser technology gives. This work intends to estimate field measured characteristics of the forest from laser data with help of regression analysis and then see which of the field measured properties that best could be estimated and which laser variables that gave the best results.
This study shows that heights has the best estimates, but biomass, diameter and volume also gives good estimates.
Scientific collaboration kartläggning av ett tvärvetenskapligt forskningsområde inom biblioteks- och informationsvetenskap
The aim of this thesis is to map the research area of scientific collaboration within Library and Information Science LIS. The purpose is to find out who is doing research in this area, who they cite and if they get cited by other scientists outside of LIS. Scientific collaboration is an interdisciplinary research area with researchers from different disciplines such as LIS, human-computer interaction, psychology and sociology. We have concentrated our study to North America, Ireland, Great Britain and Scandinavia. In order to find researchers, we visited the websites of all universities with library and information science faculties in the chosen countries.
Undervisning i naturkunskap, demokratiuppdraget och interkulturell pedagogik : Kan en interkulturell pedagogik öka intresset och motivationen för ämnet naturkunskap bland elever på samhällsprogrammet?
Since studies points out declining interest in science among students in Swedish schools, I have in this paper chosen to examine how some students at the Social Science Programme are experiencing the lessons in Natural Science and how to make lessons more interesting according to these students.The purpose of this study was to gain a greater understanding of how teachers would develop new perspectives and tools to make lessons in Natural Science more interesting. I also wanted to investigate whether an intercultural perspective could be a possible tool to increase students? interest and motivation.As a theoretical framework, I have assumed Vygotskij's sociocultural perspective, Habermas's theory of deliberative conversations and an intercultural perspective. Through a qualitative approach, I conducted interviews with students and teachers. The main results showed that students felt that natural Science lessons were too theoretical and undemocratic and that they wanted to have more student interactions, such as discussions and group works.
Culpa in contrahendo och formkravet i JB : De lege lata och de lege ferenda
Along with the development of technology, the cross-border trade is increasing and therefore there is a need for greater consumer protection. A good consumer protection creates a feeling of safety for the consumer and that by itself may help to increase cross-border trade. This is one of the reasons for why the EU has established regulatory framework for electronic commerce, for example the Directive2000/31/EC. The direc-tive strives to create a similar law for electronic commerce within the European Union. This paper?s main purpose is to ensure that the directive is implemented properly in Swedish law, and if there are other possible ways to achieve the objective, other than the ones that the Swedish legislator has chosen.
Verktyg för utveckling av terrängparker inom skidanläggningar. : Shaper
Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .
Kontrollerat och okontrollerat språk En litteraturstudie i informationsåtervinning i databaser.
This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.
