Näkövammaisten tietokoneavusteinen tiedon hankinta

The study examines various uses of computer technology in acquisition of information for visually impaired people. For this study 29 visually impaired persons took part in a survey about their experiences concerning acquisition of infomation and use of computers, especially with a screen magnification program, a speech synthesizer and a braille display. According to the responses, the evolution of computer technology offers an important possibility for visually impaired people to cope with everyday activities and interacting with the environment. Nevertheless, the functionality of assistive technology needs further development to become more usable and versatile. Since the challenges of independent observation of environment were emphasized in the survey, the study led into developing a portable text vision system called Tekstinäkö. Contrary to typical stand-alone applications, Tekstinäkö system was constructed by combining devices and programs that are readily available on consumer market. As the system operates, pictures are taken by a digital camera and instantly transmitted to a text recognition program in a laptop computer that talks out loud the text using a speech synthesizer. Visually impaired test users described that even unsure interpretations of the texts in the environment given by Tekstinäkö system are at least a welcome addition to complete perception of the environment. It became clear that even with a modest development work it is possible to bring new, useful and valuable methods to everyday life of disabled people. Unconventional production process of the system appeared to be efficient as well. Achieved results and the proposed working model offer one suggestion for giving enough attention to easily overlooked needs of the people with special abilities.

Memory Meanders : Place, Home and Commemoration in an Ex-Rhodesian Diaspora Community

Memory Meanders is an ethnographic analysis of a postcolonial migrant community, white former Rhodesians, who have emigrated from Zimbabwe to South Africa after Zimbabwe s independence in 1980. An estimated 100 000 whites left the country during the first years of independence. Majority of these emigrants settled in South Africa. In recent years President Mugabe s land redistribution program has inflicted forced expulsions and violence against white farmers and black farm workers, and instigated a new wave of emigration. Concerning the study of Southern Africa, my research is therefore very topical. In recent years there has been a growing concern to study postcolonialism as it unfolds in the lived realities of actual postcolonies. A rising interest has also been cast on colonial cultures and white colonials within complex power relationships. My research offers insight to these discussions by investigating the ways in which the colonial past affects and effects in the present activities and ideas of former colonials. The study also takes part in discussing fundamental questions concerning how diaspora communities socially construct their place in the world in relation to the place left behind, to their current places of dwelling and to the community in dispersal. In spite of Rhodesia s incontestable ending, it is held close by social practices; by thoughts and talks, by material displays, and by webs of meaningful relationships. Such social memory practices, I suggest, are fundamental to how the community understands itself. The vantage points from which I examine how the ex-Rhodesians reminisce about Rhodesia concern ideas and practices related to place, home and commemoration. I first focus on the processes of symbolic investment that go into understanding place and landscape in Rhodesia and ask how the once dwelled-in places, iconic landscapes and experiences within places are reminisced about in diaspora. Secondly, I examine how home both as a mundanely organized sphere of everyday lives and as an idea of belonging is culturally configured, and analyze how and if homes travel in diaspora. In the final ethnographic section I focus on commemorative practices. I first analyze how food and culturally specific festive occasions of commensality are connected to social and sensual memory, considering the unique ways in which food acts as a mnemonic trigger in a diaspora community. The second example concerns the celebration of a centenary of Rhodesia in 1990. Through this case I describe how the mnemonic power of commemoration rests on the fact that culturally meaningful experiences are bodily re-enacted. I show how habitual memory connected to performance is one example of how memory gets passed-on in non-textual ways.

Översättningslärarens evaluerande ställningstaganden – uttryck för lärarens kunskap

Abstract (How the evaluating commentaries of a translation teacher reflect teacher knowledge): Teachers' knowledge has been found in research to be personal and experiential. In this article I discuss teacher knowledge from the perspective of a specific translation teacher. The aim of my study was to discover what kind of knowledge a translation teacher demonstrates when she evaluates her students’ translations. Focusing on attitude expressions in my qualitative analysis, I concentrate on an interview conducted with one teacher, who talks about her students’ translations. On this basis, one may conclude that the teacher’s knowledge is based on her experiences as both a teacher and a native speaker of Swedish.
