This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

Who will ultimately master the WiFi innovation and to what degree could this innovation open new possibilities for external players to enter the mobile voice industry? Purpose: The purpose of the Master Thesis is to provide Sony Ericsson Mobile Communication AB with the most transformational scenarios, which will enable employees to recognise patterns and interpret the meaning of WiFi-related events as they unfold.

Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.

I takt med att Internetanvändandet ökar på bekostnad av andra medier blir Internet alltviktigare som marknadsföringskanal.Att synas på Internet har tidigare främst åstadkommits med hjälp av så kallade bannerannonser.Numera finns det en mängd andra sätt för att kommunicera med sina kunder somtill exempel e-postmarknadsföring och marknadsföring genom sökmotorer.Av alla varianter av marknadsföring på Internet är sökmotormarknadsföring den marknadsföringsform som växer överlägset snabbast. Det finns två varianter av sökmotormarknadsföring: vanliga annonser i form av länkar som presenteras vid sidan av sökresultatet ochsökmotoroptimering. Sökmotoroptimering, som företrädesvis behandlas i den här utredningen,syftar till att ge webbplatser höga placeringar i sökmotorer som Google, Yahoo ochMSN Search.Eftersom sökmotoroptimering, även kallat search engine optimization eller SEO, är en mycketkomplex verksamhet är det svårt för företag som vill köpa den här tjänsten att veta hur manskall gå tillväga för att få tag på en kompetent konsult. Vad som komplicerar saken ytterligareär att det har framkommit att många sökmotormarknadsförare har använt otillåtna metoder föratt ge sina kunder höga placeringar. Dessa metoder kan visserligen vara mycket effektiva menom det upptäcks riskerar både konsulten och kunden att bli utslängda ur sökmotorernasregister, även kallade index.

This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

As artificial intelligence (AI) has gained more influence in recruitment, both recruitment processes and the role of the recruiter are changing. This study aims to describe and analyze how recruiters translate, use, and relate to AI in their work. Through a qualitative method based on semi-structured interviews and document analysis, the study explores recruiters? experiences, attitudes, as well as perceived obstacles and opportunities regarding the use of AI in recruitment. With a theoretical foundation in translation theory, fashion, and imitation, the study examines how AI is not only followed as a trend, but also shaped and adapted locally through translation, depending on organizational identity and needs.

This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.
