Tillit inom illegal e-handel. En fallstudie av marknadsplatsen Silk Road

Since the beginning of the internet the criminal world has used the medium as a platform for operation.This dark web is a domain where illegal sites are flourishing due to the possibilities offered by newtechnology. Net-based criminal activity is a challenge for society as it uses hard proof technologicalsafety measures to avoid the law. Silk Road is the most prominent example, an online illicitmarketplace where drugs and illegal substances are being traded based on conventional e-commerceconcepts. This paper argues for trust as an important factor for the survival of illicit online trade andapplies existing theories on e-commerce and virtual communities. To identify patterns of trust andcommon trust-based issues among Silk Road users, a netnographic study was conducted on the site?sdiscussion forum.

Ip-telefoni med Skype som ett alternativ till PSTN för privatanvändare

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security.

Projekt Sunbaker : Utveckling av en solugn för bakning, en fältstudie i Namibia

Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.

Dynamisk modellering av VSC-HVDC : En statisk och dynamisk modelldesign o?ver VSC-HVDC fo?r implementering i ARISTO

This thesis treats the subject of a complete steady state and dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO.

Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future

Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient urban biotopes which also can be used by local urban communities. The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields. In my proposal I applied ecological design principles on three scales: the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged material.

Att spela heterosexuell : En studie av konstruktioner av genus och sexualitet i tv-spelen Prince of Persia och Fable II

The purpose of this paper is to investigate how gender and sexuality are made in the videogames Prince of Persia and Fable II, and more specifically to look at possibilities and limitations for the construction of gender and sexuality in these games. I understand videogames as an interactive media form that differs from other types of media like film and literature. It is a media form that depends on a player to be played. At the same time it is constituted by rules of how it can be played. I have analyzed my material by a method called close-playing.

Lärande med Teknik : Användning (och Icke-användning) av IT i Skolan

For a long period of time there have been discussions about the need to modernize, to keep up with the changes in our society. The schools as a result have to keep up and adapt in order for the education to be up-to-date. This includes the technological developments. Many steps have been taken and mighty sums have been invested in order to keep up the pace ? but are there any consequences from these kinds of investments? In this report I?m going to take a closer look on a recent addition to this phenomenon that were installed by means of a top-down approach and study the teachers and how they have adapted and view the change in their environment ? namely the newly installed interactive writing-boards.The questions I will study include how the teachers express their view about the installation of the interactive writing-boards.

Logotypiskt : En studie om hur digitaliseringen harförändrat logotypers utseende

In this study we are seeking to discover the norms in the design of logotypes and how they havechanged over time. To achieve this we have chosen to analyze the logotypes of twenty companies withthe largest expenditure on advertising in Sweden. We mapped chosen design attributes within the logoto discover the similarities and then we selected the five oldest brands to analyze how their logos havechanged over time. The design changes in the logotypes over time is can be related to the changingattitudes of the general public and the designers ambitions to draw on convention to create iconic designthat will spark brand-recognition. However many changes can?t be directly explained through changesin convention.
