- The majority of previous studies on vocal expression have been conducted on posed expressions. In contrast, we utilized a large corpus of authentic affective speech recorded from real-life voice controlled telephone services. Listeners rated a selection of 200 utterances from this corpus with regard to level of perceived irritation, resignation, neutrality, and emotion intensity. The selected utterances came from 64 different speakers who each provided both neutral and affective stimuli. All utterances were further automatically analyzed regarding a comprehensive set of acoustic measures related to F0, intensity, formants, voice source, and temporal characteristics of speech. Results first showed that several significant acoustic differences were found between utterances classified as neutral and utterances classified as irritated or resigned using a within-persons design. Second, listeners’ ratings on each scale were associated with several acoustic measures. In general the acoustic correlates of irritation, resignation, and emotion intensity were similar to previous findings obtained with posed expressions, though the effect sizes were smaller for the authentic expressions. Third, automatic classification (using LDA classifiers both with and without speaker adaptation) of irritation, resignation, and neutral performed at a level comparable to human performance, though human listeners and machines did not necessarily classify individual utterances similarly. Fourth, clearly perceived exemplars of irritation and resignation were rare in our corpus. These findings were discussed in relation to future research.

A harmonized GIS course curriculum for Swedish universities
- 2007
-
Ingår i: EUC'07 HERODOT Proceedings. ; , s. 10 s.-

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- With the implementation of the Bologna declaration, European and other universities must change or adjust courses and programmes so they fit into the Bologna model. In Sweden this will take place during 2007. The intention with the declaration, for example, is that a basic course in one subject at one university should be treated as equivalent to the same type of course at another university. Once a year, the recently formed section for education of the Swedish Cartographic Society gathers university lecturers and others for an education conference to discuss matters concerning higher education in geomatics, geoinformatics, geography, etc. Last year’s conference identified the need for a harmonized course curriculum in basic GIS. One of the advantages of such a course is easier transfer of study records for inclusion of course credits in study programmes at other universities. Therefore, an attempt has been made to write a harmonized course curriculum for basic GIS. The course will contain about 50% common content and about 50% of content decided by the individual university. The common content will be described as learning outcomes, and then it is up to the universities to place the learning outcomes into a context. Thanks to this common core, the course can be given for such diverse programmes as archaeology, land surveying, or economy, and still be able to include the required knowledge for students to continue on more advanced courses at other universities.

Konferensbidrag (refereegranskat)abstract
- In this full paper on innovative practice, we describe and discuss findings from dual degree study programmes that combine a master's degree in engineering with a master's degree in education. This innovative study programme design has emerged in Sweden due to an alarming demand for more Upper Secondary School teachers in STEM subjects. Studies on alumni from these programmes indicate that the graduates are highly appreciated not only as teachers in schools, but also in business and industry, e.g. in roles as IT consultants and computer science engineers. Data indicate that the breadth of the combined education, and especially leadership and pedagogical skills, are important factors for these graduates' success as engineers.

Harmonization of GI educations in Sweden and the Bologna process : viewpoints of University of Gävle
- 2006

-
Konferensbidrag (refereegranskat)abstract
- With the implementation of the Bologna declaration, many study programmes and course curricula needs to be updated and revised. This paper describes the current situation in Sweden regarding GIT educations and courses and whether a harmonization is needed. A survey was made to see which GIT courses that are given and at which level they are given at the various universities. For some universities, interviews were conducted about their courses’ contents and their strategies for determining course levels. Discussions were also made about harmonization of courses between Swedish universities. Some problems due to lack of harmonization was noted, which probably will be more severe in the future due to increased student mobility. To harmonize courses, Bloom’s revised taxonomy is put forward as a tool which is used to clearly state the level of the course in relation to learning objectives.

Prediction of Controversies and Estimation of ESG Performance : An Experimental Investigation Using Machine Learning
- 2023
-
Ingår i: Handbook of Big Data and Analytics in Accounting and Auditing. - Singapore : Springer Publishing Company. - 9789811944598 - 9789811944604 ; , s. 65-87

Bokkapitel (refereegranskat)abstract
- We develop a new methodology for computing environmental, social, and governance (ESG) ratings using a mode of artificial intelligence (AI) called machine learning (ML) to make ESG more transparent. The ML algorithms anchor our rating methodology in controversies related to non-compliance with corporate social responsibility (CSR). This methodology is consistent with the information needs of institutional investors and is the first ESG methodology with predictive validity. Our best model predicts what companies are likely to experience controversies. It has a precision of 70–84 per cent and high predictive performance on several measures. It also provides evidence of what indicators contribute the most to the predicted likelihood of experiencing an ESG controversy. Furthermore, while the common approach of rating companies is to aggregate indicators using the arithmetic average, which is a simple explanatory model designed to describe an average company, the proposed rating methodology uses state-of-the-art AI technology to aggregate ESG indicators into holistic ratings for the predictive modelling of individual company performance.Predictive modelling using ML enables our models to aggregate the information contained in ESG indicators with far less information loss than with the predominant aggregation method.

Some Properties of Aggregated Distributions over Expected Values
- 2008

Ingår i: MICAI 2008: Advances in Artificial Intelligence. - Berlin, Heidelberg : Springer Berlin/Heidelberg. - 9783540886358 - 9783540886365 ; , s. 699-709

Konferensbidrag (refereegranskat)abstract
- Software agents and humans alike face severe difficulties in making decisions in uncertain contexts. One approach is to formalise the decision situation by means of decision theory, i.e. probabilities and utilities leading to the principle of maximising the expected utility. Expected utility is here considered as a stochastic variable; under the assumption that all utility values are equally likely, and that each vector of probability values is equally likely, the probability distribution of expected utility is calculated for two, three, and four possible outcomes. The effect of these probability distributions concentrating around the middle value is explored and its significance for making decisions.

Warp Effects on Calculating Interval Probabilities
- 2009

Ingår i: International Journal of Approximate Reasoning. - : Elsevier BV. - 0888-613X .- 1873-4731. ; 50:9, s. 1360-1368

Tidskriftsartikel (refereegranskat)abstract
- In real-life decision analysis, the probabilities and utilities of consequences are in general vague and imprecise. One way to model imprecise probabilities is to represent a probability with the interval between the lowest possible and the highest possible probability, respectively. However, there are disadvantages with this approach; one being that when an event has several possible outcomes, the distributions of belief in the different probabilities are heavily concentrated toward their centres of mass, meaning that much of the information of the original intervals are lost. Representing an imprecise probability with the distribution’s centre of mass therefore in practice gives much the same result as using an interval, but a single number instead of an interval is computationally easier and avoids problems such as overlapping intervals. We demonstrate why second-order calculations add information when handling imprecise representations, as is the case of decision trees or probabilistic networks. We suggest a measure of belief density for such intervals. We also discuss properties applicable to general distributions. The results herein apply also to approaches which do not explicitly deal with second-order distributions, instead using only first-order concepts such as upper and lower bounds.

Motives for Participation in Formal Standardisation Processes for Geographic Information : An Empirical Study in Sweden
- 2017
-
Ingår i: International Journal of Standardization Research (IJSR). - : IGI Global. - 2470-8542 .- 2470-8550. ; 15:1, s. 16-28

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this article is to investigate the personal motives for participation in formalstandardization processes for geographic information. The method involved interviewing membersof technical committees at the Swedish Standards Institute, SIS. The results are that the majority ofthe interviewees are very motivated in their work and they think their participation is well-financedby their organizations allocating them to a technical committee. The main motives are to contributeto development of society and be at the forefront of development. However, this article also showsthat several members participating in this study felt that they do not have sufficient time for workingwith tasks related to their technical committees. Their daily work in their respective organizationsoften has higher priority in relation to standardization work. This contrasts with the organizationalgoals of the participating organizations and may slow down the development of standards and otherpublications due to lack of resources.

A Student Perspective on Software Development and Maintenance
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- How do Computer Science students view Software Development and Software Maintenance? To answer this question, a Phenomenographic perspective was chosen, and 20 Swedish students at four universities were interviewed. The interviews were analyzed to find in which different ways the informants, on collective level, see the phenomena of interest. The resulting outcome spaces show that software development is described in a number of qualitatively different ways reaching from problem solving, design and deliver, design for the future and then a more comprehensive view that includes users, customers, budget and other aspects. Software maintenance is described as correcting bugs, making additions, adapting to new requirements from the surroundings, and something that is a natural part of the job. Finally, conclusions from the results and additional observations are discussed in terms of their implications for teaching, and some suggestions for practical use are given.
