Changes in Swedish ToD teacher education from 1873 to the 1990s are examined through the text analysis of documents such as government regulations and syllabi and other texts such as education journals. It is argued that, parallel with the dominant rationality of the period, strands of other rationalities are to be found. In an ongoing struggle for power, one dominant rationality is challenged and gradually replaced by another. The research indicates the dominance of a patriarchal values-rationality in the decades following 1873, an instrumentaltechnical rationality during the 1930s to the 1960s and a communicative rationality from the 1970s.</p><p>Research was carried out at the National Upper Secondary School for the Deaf and Hard of Hearing in order to understand what characterizes Deaf education and the ToDs’ work, and what kind of professional skills are therefore required. The research was based on teacher interviews, student questionnaires and teaching observations in classes. Learning processes within a ToD teacher education course, as perceived by ToD students, are analysed by a study of written reflections, seminar observations and transcipts from tape-recorded seminars. ToD teacher education programs at universities in Washington D.C. and Edinburgh are also analysed.</p><p>A model for ToD education is discussed. It is argued that even if the dimension of essentialism stressing ToD basic skills and knowledge is important, the main theories for understanding the ToD education process are communicative rationality and interactionism. </p><p>It is further argued that, at societal level, the dominance of different rationalities implies different meanings of the ToD socialisation process, mediated through different historical and cultural contexts.</p><p><i>Keywords:</i> Teacher of the Deaf, educational history, research on teacher education, rationalities, symbolic interactionism.</p><p><i>Lars-Åke Domfors, Department of Education, Örebro University,</i></p><p><i>SE-701 82 Örebro, Sweden</i></p>

The shapes of naturally occurring objects characteristically involve spatial events occurring at many scales. This paper offers a symbolic approach to constructing a primitive shape description across scales for 2D binary (silhouette) shape images: grouping operations are performed over collections of tokens residing on a Scale-Space Blackboard. Two types of grouping operations are identified that, respectively: (1) aggregate edge primitives at one scale into edge primitives at a coarser scale and (2) group edge primitives into partial-region assertions, including curved- contours, primitive-corners, and bars. This approach avoids several drawbacks of numerical smoothing methods.

This report describes a program which automatically characterizes the behavior of any driven, nonlinear, electrical circuit. To do this, the program autonomously selects interesting input parameters, drives the circuit, measures its response, performs a set of numeric computations on the measured data, interprets the results, and decomposes the circuit's parameter space into regions of qualitatively distinct behavior. The output is a two-dimensional portrait summarizing the high-level, qualitative behavior of the circuit for every point in the graph, an accompanying textual explanation describing any interesting patterns observed in the diagram, and a symbolic description of the circuit's behavior which can be passed on to other programs for further analysis.

This paper explores automating the qualitative analysis of physical systems. It describes a program, called PLR, that takes parameterized ordinary differential equations as input and produces a qualitative description of the solutions for all initial values. PLR approximates intractable nonlinear systems with piecewise linear ones, analyzes the approximations, and draws conclusions about the original systems. It chooses approximations that are accurate enough to reproduce the essential properties of their nonlinear prototypes, yet simple enough to be analyzed completely and efficiently. It derives additional properties, such as boundedness or periodicity, by theoretical methods. I demonstrate PLR on several common nonlinear systems and on published examples from mechanical engineering.

Dynamics with choice is a generalization of discrete-time dynamics where instead of the same evolution operator at every time step there is a choice of operators to transform the current state of the system. Many real life processes studied in chemical physics, engineering, biology and medicine, from autocatalytic reaction systems to switched systems to cellular biochemical processes to malaria transmission in urban environments, exhibit the properties described by dynamics with choice. We study the long-term behavior in dynamics with choice. We prove very general results on the existence and properties of global compact attractors in dynamics with choice. In addition, we study the dynamics with restricted choice when the allowed sequences of operators correspond to subshifts of the full shift. One of practical consequences of our results is that when the parameters of a discrete-time system are not known exactly and/or are subject to change due to internal instability, or a strategy, or Nature's intervention, the long term behavior of the system may not be correctly described by a system with "averaged" values for the parameters. There may be a Gestalt effect.

Advertising, as an industry, reflects contemporary values whilst creating new symbols and changing both behaviour and public opinion. In the last hundred years, advertising has pervaded most areas of life, and spaces that are commer-cial free are becoming rare. The aim of this dissertation is to explore and map various social objects that create the perception of morality that exists within an advertising agency. The approach can be described as qualitative, descriptive, analytical and constructionist. The study belongs within a research field that borders on business economics/business ethics and philosophy/descriptive eth-ics. Fundamental to my study is the exploration of stories told by different key advertising practitioners. Using a symbolic interactionist approach I iden-tify important meaning carriers that together create and identify the social object “morality”. The empirical material is based on a total of 36 inter-views conducted 1998-2000 with advertising practitioners from 15 Swedish advertising agencies. In addition to the interviews, an observational study was conducted for eight months in 1998 along with a literature study. In my analysis two related areas for morality emerged; one area focusing mo-rality related to clients/consumers, and one area focusing morality within the agency/branch. Two models illustrating the results were constructed. Ethics, economics and aesthetics often find themselves on opposing sides in various situations and at different levels in the work process at the agency. The need for profit gives precedence to the economic aspect mak-ing it superior to the other two aspects, ethics and aesthetics. However, advertising practitioners that prioritise the aesthetic aspects may find them-selves be awarded a golden egg at some yearly gala. Hence, to stretch a little on morality and sin with refinement may be quite rewarding. The dissertation was preceded by and builds on a licentiate dissertation in busi-ness economics by Larsson-Eklund (2002) - “Med skaparkraft som etiskt argu-ment. En explorativ studie om moral och yrkesetik inom reklambranschen ur ett internt relationsperspektiv” (enclosed in appendix 6).

ERLANG is a concurrent functional language, well suited for distributed, highly concurrent and fault-tolerant software. An important part of Erlang is its support for failure recovery. Fault tolerance is provided by organising the processes of an ERLANG application into tree structures. In these structures, parent processes monitor failures of their children and are responsible for their restart. Libraries support the creation of such structures during system initialisation.A technique to automatically analyse that the process structure of an ERLANG application from the source code is presented. The analysis exposes shortcomings in the fault tolerance properties of the application. First, the process structure is extracted through static analysis of the initialisation code of the application. Thereafter, analysis of the process structure checks two important properties of the fault handling mechanism: 1) that it will recover from any process failure, 2) that it will not hide persistent errors.The technique has been implemented in a tool, and applied it to several OTP library applications and to a subsystem of a commercial system the AXD 301 ATM switch.The static analysis of the ERLANG source code is achieved through symbolic evaluation. The evaluation is peformed according to an abstraction of ERLANG’s actual semamtics. The actual semantics is formalised for a nontrivial part of the language and it is proven that the abstraction of the semantics simulates the actual semantics. / ASTEC

Sustainability is a growing trend and companies are increasingly engaging sustainability in their core business strategy. One example of how this is manifested is through the development of products that are  labelled as energy-efficient. There is a lack of insights into how consumers perceive and gain benefits from such sustainable products, particularly so regarding the nonfunctional and non-economical benefits and into how culture influences those benefits. The purpose of this study is to investigate consumer perceived non-functional and non-economical benefits that are associated  with energy-efficient products,  in order to gain a deeper understanding on how the Swedish compared to the Thai culture influence consumers perception of energy efficient products within the home appliance industry. The literature review regarding the  symbolic meaning of products concludes that the most relevant perceived benefits of products includes emotional-, self-expressiveness-, and social benefits. A cross-cultural quantitative study performed in Sweden and Thailand determines that culture influences consumers understanding of products and thereby influence their perceived benefit from energyefficient home appliances. How culture influences consumer perceived benefits depends on the characteristics of the different cultural dimensions established by Hofstede (2010), involving: power distance, masculinity, individualism, uncertainty avoidance, and long-term orientation.

Television often portrays African Americans in unfavorable positions in comparison to Caucasians. Typically these unfavorable depictions reinforce negative stereotypes associated with African Americans. Research indicates that television portrayals can influence people’s attitudes toward one another. A question left unanswered by current research: are mass-mediated images as influential at reversing or counteracting stereotypes as they are at reinforcing them? An experiment with undergraduate students was conducted to investigate the relationship between the positive portrayal of African Americans and subsequent racial attitudes. Participants viewed a video clip with either an African American or Caucasian chairman for the Georgia Division of Public Health. The clip included a still photograph of the chairman and was accompanied by a pre-recorded voice addressing treatments for lung cancer patients. At the beginning of each class, professors showed students the video after which the class lecture proceeded as scheduled. Just before the class ended a researcher entered the class and told students he/she was doing a survey on racial attitudes. Students were then given a questionnaire regarding racial attitudes toward African Americans. Between the time of the video viewing and the completion of the survey, students were not informed that one was related to the other. Subjects also completed an evaluation of the speaker in the video and of the health message.

In this thesis, a review of Kenneth Burke's use of the term attitude in his published works as well as in some unpublished notes, drafts and letters, is performed. Three periods of different usage are found. Early works feature a pervasive attitude with elements of both body and mind. This attitude is then subsumed into the pentad and the physiological connection is diminished, but attitude is given an important function as a connective between action and motion. The later Burke reinstates attitude as central to his theory of symbolic action, reconnects it to the physiological and includes it in the Pentad with parsimony-inducing effect. The attitude is then found to aid rhetorical analysis and show promise in being able to help analyse expressions not wholly in the realm of the conscious, be they in the form of a Bourdieu social practice or barely conscious rhetorical markers in conversation.
