Leder icke användarcentrerad systemutveckling till låg användbarhet?
Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.
Matematikundervisning i Waldorfskola respektive kommunal skola : En kvalitativ undersökning av två olika grundskolor
The purpose of this study has been to compare teachers' differing methods of teaching mathematics and their perspectives on the learning process in a municipal school to a Waldorf school. The study has examined which approach best promotes student engagement and learning in mathematics in the first three years of schooling. The study is based on four interviews. The informants? accounts are interpreted using theories from previous research.
Att upprätthålla krisberedskap : En studie av E.ONs krisorganisation
The purpose of this paper is to investigate how organisations can keep their crisis preparedness alert although crises do not occur often. A crisis organisation will lay dormant within a larger organisation for long periods of time. This may cause a problem when a crisis does occur if the preparedness has not been kept alive.From previous researchers that we have studied within this field we have identified two distinct methods to do this. The first focuses on the importance of detailed crisis plans, while the other method suggests that it is more essential to develop specific competencies with the employees. We also find that keeping knowledge within an organisation is a matter of organisational learning and memory which we therefore discuss and analyse.We have performed an interview study at E.ON in Örebro, and we have also had the opportunity to read E.ON?s crisis plan.
Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten
Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.
Införande av evidensbaserade metoder: ett kommunperspektiv
This thesis is composed within the framework of the supplementary course in psychotherapy concentrating on family therapy (60 credits) arranged by Lund University's affiliate in Västerås, Sweden.The purpose of this thesis has been to explore how the idea to initiate evidence based methods in the workings of the Individual and Family Care Department of the City of Västerås was born. Furthermore the thesis will explore if consideration for methods of theoretical implementation are implied. The study assumes a qualitative attempt and is based on semi-structured interviews from three levels within the organization, including both management and operation.Theories on organization,implementation and the theory on change strategies have been used as a theoretical starting point.The study result shows that introduction of evidence based methods in the City of Västerås is based on the experiences of the organization regarding the need to develop and increase social services contributions to non-institutional care. Experiences from expensive transferrals to institutions which only occasionally produced satisfactory results were a contributing factor. New published research and a strong interest and desire inside the department to improve and change social services contributions have naturally been a positive influence for the development.
Krishantering : Granskning av krisarbete i grundskolan
My purpose in this paper is to study teachers' work in reading and writing in primary school and special school. I want to find out if they use the same methods, strategies and materials to help students learn to read and write. I will find out the answer to my purpose by performing two qualitative observation and two qualitative interviews. Lundberg (2010) is the researcher I relate to during my study. Through observation, I see how teachers work with students in the classroom during a lesson in the Swedish language. During the interviews, I received answers to how teachers work with language, the materials, methods and strategies they use. I found out that teachers use specific strategies when they help their students. They use a work material that is tailored to curriculum in Swedish language and it is based on the phonics method. .
Om individanpassad matematikundervisning i praktiken : en intervjustudie med tre pedagoger i grundskolans tidigare år
Studies show that the performance of Swedish students in the subject of mathematics is to be considered somewhat average. The government has therefore decided to assist with extended project funding to schools on a local level in order to improve these results.Schools will, unlike before, practice teaching suited for the individual needs of students based on their previous experiences, knowledge level, language comprehension and their environment. This is also clearly stated in the Swedish school curriculum.My survey shows how three teachers in primary school actually work towards individualized teaching of mathematics and what methods they prefer. This survey also answered what these teachers considered to be the obstacles and opportunities with individualized teaching methods. The difference in approach of how to practice this has also been documented.The survey, based on interviews and class observations, have been analyzed and compared to previous research and theories in the field of teaching practices.

Lövängen i nordöstra Skåne :
The purpose of this paper is to study how the wooded hay meadow of the forest district of northeastern Scania is preserved today, and what local history it has, to thereby achieve a better understanding of the dynamics of the landscape and the complex of problems involved in keeping a historical element of the cultural landscape alive. To accomplish this, literature concerning the subject has been studied, experts have been consulted and an example, the old farm Sporrakulla in Östra Göinge municipality, has been studied. The paper states that the wooded hay meadow constitutes an important part of the history of northeastern Scania, where it provided leaf fodder and hay for the farmers keeping cattle. Today, however, only a few wooded hay meadows remain. One of these is the studied example at Sporrakulla, where juridical protection like Natura 2000 and financial support of maintenance like miljöersättningar make sure that the wooded hay meadow will remain.
Undervisningsmetodens påverkan på skolbiblioteksanvändningen: exemplet problemorienterad undervisningsmetod
This thesis is an attempt to study whether if problem-oriented teaching implies a moreadvanced use of school libraries than other teaching methods.Teachers have been interviewed about what kind of information they and their pupils need,and where they find their information. Another question is whether the problem-orientedteaching method makes it easier for the pupils to find information in school libraries thanother teaching methods do.The result of the study is that a problem-oriented teaching method creates opportunitiesfor the school library to become an important place for information retrieval. This teachingmethod is a major, but not the only determinal factor. Other contributing factors could beteamwork between teachers and school librarians and the existence of learning aids..

Tillväxtreaktion hos skärmträd i högskärm av gran i Medelpad :
Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity.
This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).
Kollektiv etnisk identitet som en central faktor i reproduceringen av socialt kapital inom etniska institutioner.
The purpose of this study is to first investigate how a group of Syriac women participating in the Syriac/Aramaic Academics Association (SAAF ? Syrianska/Arameiska Akademikerförbundet) at a Swedish university perceive their ethnic identity, and maintain it in the mainstream Swedish society. Furthermore, it considers whether SAAF as an ethnic institution provides an arena for the reproduction of social capital in interaction with the women's families. This study is based on previous research and theories of ethnic identity and its role in the building of social capital within so-called ethnic groups. The method used for this study involves qualitative interviews, to achieve its aims.
Effektiv ordinlärning? : En studie av aktiv ordinlärning i engelska inom gymnasieskolan
The purpose of this essay is to discuss and compare different ways of learning new words and expanding your vocabulary in a foreign language. This is done by an examination of relevant literature and available research, as well as by an empirical study with two upper secondary school classes, in which two different methods are put to the test: one traditional method of the kind that is found to be most common in second language acquisition, and one designed to take existing research into account. The results show that, although effective in the initial stages of acquisition, the traditional method, where words are learned in isolation and via translation to L1, results in a very limited form of knowledge. A big part of the words acquired via this method is also forgotten soon afterwards. The other method, where words were learned and tested in its proper context, was found to result in a broader form of vocabulary knowledge, covering more aspects, and that remained over time.
Fiende utan ansikte - en jämförande studie av terroristgrupper under efterkrigstiden
AbstractThe purpose of this theses is to compare three different political groups, The IRA, The Baader-Meinhof group and the Al Qaida, who have all used terroristic methods to achieve their separate goals.By finding out about their history, goals, structures and methods I have made a comparison to see what joins them, what separates them, what originated the birth of their movements and how they can or could proceed with their violent actions to the point that they had actual impact on international politics.It has all been done through a litteraturebased study.My focuse has been on Al Qaida since it's is the only one of the three who is still active today and who, through its cellstructure, represents a new form of global terrorism that may have great influence on the structural patterns of other political groups and criminal organizations in the future.Key words:Al QaidaBaader-MeinhofIRATerrorismCellstructure.
