Vetenskapsteoretiska och metodologiska perspektiv på tidsgeografiska visualiseringsmodeller. -En fallstudie i samhällsvetenskaplig visualisering

In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.

Design och utveckling av IT-verktyg - ger ringar på vattnet i en organisation

This Bachelor Thesis in the area of Computer science and Work Science describes the process of design and development of an IT-tool between the municipality of Ron-neby and TietoEnator a development and consultancy firm, the Gothenburg office. The thesis focuses mainly on the cooperation between the consultant designer and the local municipal. Through cooperation, the organisation is incorporated into the tool and the tool is incorporated into the organisation. Concepts that are central in this thesis are design, cooperation and tailoring. A question raised is, if distance work and extensive cooperation might be a good way of working in the process of design and development, when the organisation is being incorporated into the tool. Advan-tages and disadvantages of this way of working are discussed. Our studies show that distance work is a good complement for personal meet-ings between designer and co-developer.

Socialarbetares syn på datorspelande ungdomar : En intervjustudie om socialarbetares problematisering av ett nytt fenomen

The purpose of our study is to describe and understand whether, and if so, how social workers in school and in social services construct computer gaming adolescents as a social problem. We chose social workers who encounter adolescents with different problems. We have conducted qualitative interviews with vignettes to capture the social workers' reasoning about computer gaming adolescents and how they handle this in their work. The study shows that all social workers we interviewed had encountered adolescents with troubling computer gaming habits. In the study, all agree that computer gaming becomes a problem when it leads to deviant behaviour such as not going to school, staying up all night and so on.

Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

Riskanalys inom intrångsäkerhet på webbplatser

Attacker och intrång på webbservrar är idag vanligt förekommande. Webben gör det lätt för hackare, knäckare och andra inkräktare att hitta sårbara servrar, och det finns gott om tips att hämta för den som vill lära sig hur man gör intrång. Det finns ett flertal olika intrångsmetoder som utnyttjar olika typer av svagheter i datorsystemen. Denna uppsats inriktar sig på svagheter i webbplatsernas serverskriptsystem, dess skriptkod och konfiguration. Syftet är att undersöka huruvida intrång kan göras med endast en webbläsare via webbplatsens offentliga webbsidor. Genom att kombinera tre olika metoder - litteraturundersökning, en enkät och ett experiment - undersöker uppsatsen hur serverskriptintrång fungerar.

Konstskolan

Abstract I have made a Website called ?Art school? for Liljevalchs art Gallery, Culture administration in Stockholm and Culture school in Stockholm. It is with scholarship from these that this Website has been possible. The work whit the ?Art school? started in the autumn of 2005 and ended in May 2006 on distance from Stockholm towards Blekinge technology school in Karlshamn. The Webb place is for the general public, but most for people who have interest in art and for those how want to learn more painting in different mediums. This Websites I name: oil, watercolour, acrylic, coal, gouache, and graphite. On each one of these mediums you?ll get to know about their history, what technique they have, what sort of material you need, practise and tip.

Hur använder pedagogerna och barnen datorn i förskola och i förskoleklass?

The purpose with my degree project is to investigate the use of computers within the daily activity in three preschools and one preschool class. I have designed a survey that I distributed to the staff. The purpose of my work is to investigate how a number of preschool teachers and children in a few preschools and one preschool class in a medium-sized Swedish town are using the computer in their activities.My study shows that the computer is frequently used, both of the children and teachers, but also together. The children in my study are using the computer to play games, listen to music, and go into the websitewww.youtube.com, but also in order to write and count.  The teachers primarily use the computer to document, check their e-mail and listen to music.

Ingenting är sant, allt är tillåtet : En kvalitativ studie om historiska datorspel som Assassin?s Creeds påverkan för det oavsiktliga lärandet och dess pedagogiska möjligheter

The main purpose of this study is to investigate the unintentional learning that happens during the use of computer games. With the use of interviews with students in the ages 13-15 who all have played the game series Assassin?s Creed, and then compared them with students who does not play the game, we have been able to identify that some learning is taking place, but that the student?s attitude towards the subject, and their maturity, also is vital for the learning. Even tough, the students who didn?t really enjoy history as a subject showed better knowledge after playing the game, than the students who hadn?t played at all, which indicates that computer games can be a good source for learning.

En undersökning i datasäkerhet för hemanvändare - Är det nödvändigt att använda brandvägg?

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

"The Machine Made Me Do It!" : An Exploration of Ascribing Agency and Responsibility to Decision Support Systems

Are agency and responsibility solely ascribable to humans? The advent of artificial intelligence (AI), including the development of so-called ?affective computing,? appears to be chipping away at the traditional building blocks of moral agency and responsibility. Spurred by the realization that fully autonomous, self-aware, even rational and emotionally-intelligent computer systems may emerge in the future, professionals in engineering and Computer science have historically been the most vocal to warn of the ways in which such systems may alter our understanding of computer ethics. Despite the increasing attention of many philosophers and ethicists to the development of AI, there continues to exist a fair amount of conceptual muddiness on the conditions for assigning agency and responsibility to such systems, from both an ethical and a legal perspective. Moral and legal philosophies may overlap to a high degree, but are neither interchangeable nor identical.
