Towards an epistemological theory of historical consciousness

This paper presents a theoretical analysis of the concept of historical consciousness. It argues that a focus on the epistemological problems of the concept can be a way of constructing a theory of the concept that both incorporates the diverse perspectives that exist in research about the concept and specifies how a historical consciousness can be developed in an individual.

A Contour-based Separation of VerticallyAttached Traffic Signs

This report presents an algorithm for locating the cut points for and separatingvertically attached traffic signs in Sweden. This algorithm provides severaladvanced digital image processing features: binary image which representsvisual object and its complex rectangle background with number one and zerorespectively, improved cross correlation which shows the similarity of 2Dobjects and filters traffic sign candidates, simplified shape decompositionwhich smoothes contour of visual object iteratively in order to reduce whitenoises, flipping point detection which locates black noises candidates, chasmfilling algorithm which eliminates black noises, determines the final cut pointsand separates originally attached traffic signs into individual ones. At each step,the mediate results as well as the efficiency in practice would be presented toshow the advantages and disadvantages of the developed algorithm. Thisreport concentrates on contour-based recognition of Swedish traffic signs. Thegeneral shapes cover upward triangle, downward triangle, circle, rectangle andoctagon. At last, a demonstration program would be presented to show howthe algorithm works in real-time environment.

Populärmusik i TV-reklam : En kvalitativ undersökning av musiken som betydelsebärande teckensystem

This paper examines a popular music song (Heartbeats by Jose Gonzalez) as a sign system in television advertising. The study was conducted through qualitative questionnaires in connection to an audio-visual method of analysis called Masking. The method facilitates the analysis of isolated parts in the audio-visual spectrum by masking/hiding parts of the audio-visual totality.The survey had seven respondents where a hermeneutic epistemological approach was used. For the analysis Cooper's theory of brand identity (Practical and Symbolic Attitudes to Buying Brands) was used together with an interaction model for music in audio-visual advertising called "Modes of music-image interaction”. The results showed that the music was associated with values as genuine, honest, responsibility, purity, independence and innovation. The music's symbolic values helped to position the brand in a lifestyle context. The music also helped to express the target group’s identity and attitudes by being innovative and independent. It also enhanced the perception of the visual colour rendition in the film. In general the television advertisement perceived more positive and entertaining when the music was present. In other words the music's social and cultural position contributed to raise the film's credibility. A deeper social and cultural value was created in the movie through resonance between symbolic values of the music and symbolic values of the film.

Concreteness in Business letters : a Corpus-based Analysis of British and Pakistani English

Linguistic features of business letters have been a research target of both linguists and business writers. In this study, the language of British and Pakistani Business letters was compared and contrasted in terms of concreteness and abstractness. A corpus of 100 business letters from Inner Circle and Outer Circle writers were collected for analysis. The findings of the study revealed that British writers use more specific and concrete nouns, definite determiners, numeral, possessive and demonstrative adjectives, cohesive and rhetorical devices than the Pakistani Writers in order to be become concrete and vivid in their communication. The present findings are rather corpus specific since the data include only two countries; however this study may lead to further cross circle research including Expanding Circle research of business letters in terms of concreteness and abstractness. The issue of concreteness in Cross-circle business English can also be studied from psychological, sociological and anthropological perspectives in future Research.

Ways of knowing in ways of moving : A study of the meaning of capability to move

The overall aim of this thesis has been to investigate the meaning of the capability to move in order to identify and describe this capability from the perspective of the one who moves in relation to specific movements. It has been my ambition to develop ways to explicate, and thereby open up for discussion, what might form an educational goal in the context of movements and movement activities in the school subject of physical education and health (PEH). In this study I have used a practical epistemological perspective on capability to move, a perspective that challenges the traditional distinction between mental and physical skills as well as between theoretical and practical knowledge. Movement actions, or ways of moving, are seen as expressions of knowing. In order to explore an understanding of the knowing involved in specific ways of moving, observations of  actors’ ways of moving and their own experiences of moving were brought together. Informants from three different arenas took part: from PEH in upper secondary school, from athletics and from free-skiing. The results of the analyses suggest it is possible to describe practitioners’ developed knowing as a number of specific ways of knowing that are in turn related to specific ways of moving. Examples of such specific ways of moving may be discerning and modifying one’s own rotational velocity and navigating one’s (bodily) awareness. Additionally, exploring learners’ pre-knowing of a movement ‘as something’ may be fruitful when planning the teaching and learning of capability to move. I have suggested that these specific ways of knowing might be regarded as educational goals in PEH. In conducting this study, I have also had the ambition to contribute to the ongoing discussion of what ‘ability’ in the PEH context might mean. In considering specific ways of knowing in moving, the implicit and taken-for-granted meaning of ‘standards of excellence’ and ‘sports ability’can be discussed, and challenged.

Kung slår dam : våldsforskningsmetodologi i ett våldsamt jämställt Sverige

King captures queen. Methodology in research on violence in violently equal Sweden Research and debate on violence against women in a Swedish context is here discussed from a perspective that focuses on the different understandings and epistemological claims behind existing positions. I crystallize a dominant perspective on violence, centred around fragmentation/deviance, and a challenging feminist understanding, centred around coherence/normality. I relate these understandings to a wider set of methodological choices and epistemological claims within research on violence against women, captured in what I call a discourse on partner violence (fragmentation) and a feminist discourse on men’s violence against women (coherence). The article also examines the reactions, in media and academic life, that a quantitative study on men’s violence against women in Sweden provoked, Captured queen, men’s violence against women in equal Sweden. A prevalence study (Lundgren et al 2001). By applying a coherent methodological approach, stemming from the feminist discourse on violence against women, the study seems to have placed itself outside what was comprehensible for many voices in the debate (from media and the academic field). I discuss the hostile reactions the study aroused, in relation to its methodology and the above presented conflicting understandings that occupy the research field “violence against women”.

Visualization of spirography-based objective measures in Parkinson's disease

Objective: To investigate whether advanced visualizations of spirography-based objective measures are useful in differentiating drug-related motor dysfunctions between Off and dyskinesia in Parkinson’s disease (PD). Background: During the course of a 3 year longitudinal clinical study, in total 65 patients (43 males and 22 females with mean age of 65) with advanced PD and 10 healthy elderly (HE) subjects (5 males and 5 females with mean age of 61) were assessed. Both patients and HE subjects performed repeated and time-stamped assessments of their objective health indicators using a test battery implemented on a telemetry touch screen handheld computer, in their home environment settings. Among other tasks, the subjects were asked to trace a pre-drawn Archimedes spiral using the dominant hand and repeat the test three times per test occasion. Methods: A web-based framework was developed to enable a visual exploration of relevant spirography-based kinematic features by clinicians so they can in turn evaluate the motor states of the patients i.e. Off and dyskinesia. The system uses different visualization techniques such as time series plots, animation, and interaction and organizes them into different views to aid clinicians in measuring spatial and time-dependent irregularities that could be associated with the motor states. Along with the animation view, the system displays two time series plots for representing drawing speed (blue line) and displacement from ideal trajectory (orange line). The views are coordinated and linked i.e. user interactions in one of the views will be reflected in other views. For instance, when the user points in one of the pixels in the spiral view, the circle size of the underlying pixel increases and a vertical line appears in the time series views to depict the corresponding position. In addition, in order to enable clinicians to observe erratic movements more clearly and thus improve the detection of irregularities, the system displays a color-map which gives an idea of the longevity of the spirography task. Figure 2 shows single randomly selected spirals drawn by a: A) patient who experienced dyskinesias, B) HE subject, and C) patient in Off state. Results: According to a domain expert (DN), the spirals drawn in the Off and dyskinesia motor states are characterized by different spatial and time features. For instance, the spiral shown in Fig. 2A was drawn by a patient who showed symptoms of dyskinesia; the drawing speed was relatively high (cf. blue-colored time series plot and the short timestamp scale in the x axis) and the spatial displacement was high (cf. orange-colored time series plot) associated with smooth deviations as a result of uncontrollable movements. The patient also exhibited low amount of hesitation which could be reflected both in the animation of the spiral as well as time series plots. In contrast, the patient who was in the Off state exhibited different kinematic features, as shown in Fig. 2C. In the case of spirals drawn by a HE subject, there was a great precision during the drawing process as well as unchanging levels of time-dependent features over the test trial, as seen in Fig. 2B. Conclusions: Visualizing spirography-based objective measures enables identification of trends and patterns of drug-related motor dysfunctions at the patient’s individual level. Dynamic access of visualized motor tests may be useful during the evaluation of drug-related complications such as under- and over-medications, providing decision support to clinicians during evaluation of treatment effects as well as improve the quality of life of patients and their caregivers. In future, we plan to evaluate the proposed approach by assessing within- and between-clinician variability in ratings in order to determine its actual usefulness and then use these ratings as target outcomes in supervised machine learning, similarly as it was previously done in the study performed by Memedi et al. (2013).

Om lärarskapets moraliska dimension : ett perspektiv och en studie av lärarstuderandes nätbaserade seminariesamtal

In this dissertation, an educational perspective called the moral dimension of teaching is developed. The work includes a theoretically informed discussion from a pragmatist point of view in which the concept of pedagogical rhythm is introduced. The concept captures the need for teachers to regularly shift their intentions and occasionally act in contradictory ways as a consequence of the moral which emerges from interaction in pedagogical situations. Using this perspective, criteria are developed for the characteristics of discussions of the work of teachers, which are desirable in order for students in pre-service teacher education to have opportunities to develop their teachership. Secondly, the educational perspective as it is conceptualised serves as a theoretical framework for a study of discussions taking place in net-based seminars among students in teacher education. The study consists of 14 recorded seminars in which discussions of the work of teachers are analysed in terms of content and direction for reflection. The result of the analysis is a construction of four different focal points for processes of making judgements: existential, performative, critical and professional. Mainly the performative, and to some extent the critical, focal points appear to be supported by the net-based environment, although potential for the professional focal point is found when available tools in net-based settings are used in deliberate ways. Finally, based on these four focal points, possible future predispositions among student teachers are deliberated. Student teachers’ future opportunities to develop a moral and epistemological authority are discussed, as well as teachers’ general opportunities to exercise professional responsibility. The conclusion emphasises that a perspective such as the one developed in the dissertation is important, as it creates an understanding for the need to educate student teachers to exercise a form of responsibility that goes beyond being accountable to society.

Dokumentationens dilemman : Förskollärare samtalar om pedagogisk dokumentation

Abstract  Pedagogical documentation is a certain procedure for documenting that, in recent years, has been embraced in several Swedish preschools. Teachers document children’s actions and conversations usually by photos or video recordings. This documentation is to be used for a pedagogical purpose. However, studies and governmental inspections have shown that pedagogical documentation gives rise to many questions among preschool teachers. The purpose of this study is to gain insight into what is being expressed when preschool teachers discuss pedagogical documentation, focusing on themes of content and on the participants’ expressions of their points of view. The data is comprised of transcriptions from audio recordings of discussions conducted in a research circle. The participants are eight preschool teachers that met over the course of one year. Each meeting focused on the documentation provided by a different participant. In that way the contents of the discussions were framed by the teachers own questions and narratives. Theoretically, the study departs from Social Constructionism and Discursive Psychology. The preschool teachers’ utterances have been analyzed using concepts of interpretative repertoires and ideological dilemmas. The results show the main themes to be: Knowledge content in a preschool setting, children’s learning, the teacher’s role and implementation of pedagogical documentation. The participants’ joint position is that the knowledge content at the preschool level is defined by the curriculum for the preschool. Concerning children’s learning and the teacher’s role, two main standpoints are disclosed. Ideologically those standpoints derive from two opposing theories of education. Based on how the standpoints have been expressed I have called them ”predetermined learning” versus ”non-predetermined learning”. One main distinction between the standpoints is that predetermined learning emphasizes the results of learning, while non-predetermined learning emphasizes the processes of learning. The participants’ utterances show that teachers tend to subscribe to the idea that there is only one acceptable way of working with pedagogical documentation. This sometimes creates performance anxiety and feelings of not succeeding and has led to arguments advocating an alternate approach; pedagogical documentation can be done in many ways. The ideological dilemmas within the discourse can be perceived as resources by which the participants argue about knowledge, learning, teaching and about the implementation of pedagogical documentation.

Capability outcomes from educational and ICT capability inputs : an analysis of ICT use in informal education in Kenya

In the field of Information and Communication Technologies for Development (ICT4D) ICT use in education is well studied. Education is often seen as a pre-requisite for development and ICTs are believed to aid in education, e.g. to make it more accessible and to increase its quality. In this paper we study the access and use of ICT in a study circle (SC) education program in the south coast of Kenya. The study is qualitative reporting results based on interviews and observations with SC participants, government officers and SC coordinators and teachers. The study builds on the capability approach perspective of development where individuals’ opportunities and ability to live a life that they value are focused. The aim of the study is to investigate the capability outcomes enabled through the capability inputs access and use of ICT in education as well as the factors that enabled and/or restricted the outcomes. Findings show that many opportunities have been enabled such as an increase in the ability to generate an income, learning benefits, community development and basic human development (e.g. literacy and self-confidence). However, conversion factors such as a poorly developed infrastructure and poor IT literacy prevent many of the individuals from taking full advantage of the ICT and the opportunities it enables.
