Expressing ‘confirmation’ in Swedish: the interplay of word and utterance prosody

Konferensbidrag (refereegranskat)abstract
- An exploratory study on the prosodic signaling of ‘confirmation’ in Swedish is presented. Pairs of subjects read short dialogs, constructed around selected target words, in a conversational style. A falling utterance intonation was found on the target word, and the signaling of word prosody (lexical pitch accent) appeared to be, to a certain degree, optional.

- In recent years the Swedish Police Force (SPF) have encountered greater demands on availability and 24/7 services when dealing with errands that are regarded as low priority compared to regular police work, e.g. collecting tips from the public. One attempt to meet these increasing demands was the development of a mobile communications platform that allowed the public to communicate easily with the SPF using their own mobile phones by sending SMS and MMS. The focus of this paper is on the early phases of development of this m-service, in particular, on the specific technical issues such as interoperability and standards used by the actors on the scene affecting the development of mobile information systems. The learning experiences are as follows: First, mobile communication platforms have a large potential for contributing to the field of emergency management information systems since they can be based on open and nationally accepted standards. Second, global and national standards for sending multimedia messages are not always truly standardized. Operators and mobile phone manufacturers make minor alterations and interpretations of the standard and thereby some of the benefits found in standards disappear. Third, when developing mobile information systems we suggest and recommend that the analysis phase should be enhanced compared to traditional system development, and it should address the interoperability between mobile phones on one hand and operators on the other hand.

- In this study, we present a novel method to isolate and enrich low concentrations of Campylobacter pathogens. This method, Acanthamoeba-Campylobacter coculture (ACC), is based on the intracellular survival and multiplication of Campylobacter species in the free-living protozoan Acanthamoeba polyphaga. Four of the Campylobacter species relevant to humans and livestock, Campylobacter jejuni, C. coli, C. lari, and C. hyointestinalis, were effectively enriched by the coculture method, with growth rates comparable to those observed in other Campylobacter enrichment media. Studying six strains of C. jejuni isolated from different sources, we found that all of the strains could be enriched from an inoculum of fewer than 10 bacteria. The sensitivity of the ACC method was not negatively affected by the use of Campylobacter-selective antibiotics in the culture medium, but these were effective in suppressing the growth of seven different bacterial species added at a concentration of 10(4) CFU/ml of each species as deliberate contamination. The ACC method has advantages over other enrichment methods as it is not dependent on a microaerobic milieu and does not require the use of blood or other oxygen-quenching agents. Our study found the ACC method to be a promising tool for the enrichment of Campylobacter species, particularly from water samples with low bacterial concentrations.

Colour development in copper ruby alkali silicate glasses : Part 1. The impact of tin (II) oxide, time and temperature
- 2007
-
Ingår i: Glass Technology, Eur J Glass Sci Technol A. - : Society of Glass Technology. ; 48:2, s. 101-108
-
Tidskriftsartikel (refereegranskat)abstract
- The development of the red colour in copper ruby alkali silicate glasses has been studied by means of ultraviolet/visible spectroscopy, TEM and EXAFS. The results show that in both red and slightly overstruck, brownish glasses the colour is due to clusters of metallic copper. Before striking non-coloured glasses contain mainly cuprous ions, Cu+. Tin acts as a reducing agent but also has an accelerating effect on colour development.

Selenium : molybdenum-based coloration of alkali silicate glasses
- 2007
-
Ingår i: Glass Technology. - : Society of Glass Technology. - 0017-1050. ; 48:5, s. 213-221
-
Tidskriftsartikel (refereegranskat)abstract
- The interaction between selenium and molybdenum in reduced alkali silicate melts, resulting in red glasses has been studied. The oxidation state of Mo is Mo(VI) as evidenced by XANES and ESCA results. Selenium is present in a reduced state, as indicated by ultraviolet/visible spectroscopy and XANES. The colour is described by ultraviolet/visible spectra and CIE colour coordinates. The main absorption peaks are at 450 and 540 nm. Similar bands are reported for MoOSe32−. Several commonly used glass components must be avoided in the batch, as they prevent formation of the red colour.

Critical Thinking in Scholarship: : Meanings, Conditions and Development
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this thesis is to explore the phenomenon of critical thinking in scholarship as regards its meanings, conditions, and development using a hermeneutic phenomenological approach. This exploration takes its departure in ancient Greece, following a historical movement of the phenomenon up to present day perspectives on critical thinking, revealing a range of different meanings and conditions. Thus, the reader is invited to follow my synthetic meaning constitution of the phenomenon of critical thinking as it appears in different philosophical and educational texts. Through this gradual process of meaning constitution it is shown that the scholarly critical thinker is in one way or another concerned with abstract relationships, in order to either master, understand, or change the world. These underlying interests may, in turn, be derived from the critical thinker’s sense of responsibility towards God, nature, society, and humanity as a whole. It also appears that even though critical thinking in scholarship is traditionally framed within rational and principle based thinking, the development of the meaning of critical thinking is on its way to new dimensions. Besides rationality, other qualities of critical thinking are highlighted, such as reflective thinking, emotions, creativity, imagination, and intuition. Despite the fact that research on critical thinking has started to move in new directions, educational policy documents implicitly conceptualize critical thinking in traditional terms. This means that the phenomenon is captured within its own instrumentality, with no further concern for its possible ends. The same circumstance can be noted in relation to contemporary perspectives on critical thinking, which tend to focus on the process of critical thinking, since critical thinking is implicitly understood as an assurance of attaining normatively good ends. However, critical thinking is a phenomenon that is future oriented, involving its intention and possible ends. Against this background, it is therefore argued that critical thinking receives its most critical feature when intention, process and end constitute a constructive interrelated whole.
