  • Learner Corpus Anonymization in the Age of GDPR: Insights from the Creation of a Learner Corpus of Swedish
  • 2018
  • Ingår i: Proceedings of the 7th Workshop on NLP for Computer Assisted Language Learning (NLP4CALL 2018) at SLTC, Stockholm, 7th November 2018 / edited by Ildikó Pilán, Elena Volodina, David Alfter and Lars Borin. - Linköpings universitet : Linköping University Electronic Press. - 1650-3686 .- 1650-3740. - 978-91-7685-173-9
  • Konferensbidrag (refereegranskat)abstract
    • This paper reports on the status of learner corpus anonymization for the ongoing research infrastructure project SweLL. The main project aim is to deliver and make available for research a well-annotated corpus of essays written by second language (L2) learners of Swedish. As the practice shows, annotation of learner texts is a sensitive process demanding a lot of compromises between ethical and legal demands on the one hand, and research and technical demands, on the other. Below, is a concise description of the current status of pseudonymization of language learner data to ensure anonymity of the learners, with numerous examples of the above-mentioned compromises.

  • Optical activity in racemic chromium(III) tartrate solution induced by circularly polarized irradiation
  • 1977
  • Ingår i: Inorganic and Nuclear Chemistry Letters. - 0020-1650. ; 13:8, s. 355-362
  • Tidskriftsartikel (refereegranskat)abstract
    • Alkaline solutions of Cr(III) in racemic tartrate (=RS-T) become optically active when irradiated with circularly polarized light. This is assigned to the photo-inversions Λ-Cr (R-T)3X− → Δ-Cr(R-T)3X− and Δ-Cr(S-T)3X− → Λ-Cr(S-T)3X−, but ligand substitutions such as Cr(R-T)3 → Cr(R-T)2S-T, may occur as well. In the dark the activity slowly (k ca. 2 × 10−5 s−1) decays back to zero.

  • KILLE: a Framework for Situated Agents for Learning Language Through Interaction
  • 2017
  • Ingår i: Linköping Electronic Conference Proceedings. - Linköpings universitet : Linköping University Electronic Press. - 1650-3686 .- 1650-3740. - 978-91-7685-601-7
  • Konferensbidrag (refereegranskat)abstract
    • We present KILLE, a framework for situated agents for learning language through interaction with its environment (perception) and with a human tutor (dialogue). We provide proof-of-concept evaluations of the usability of the system in two domains: learning of object categories and learning of spatial relations.

    • Objective: To investigate the impact of disease-related aspects on long-term variations in fatigue in persons with rheumatoid arthritis. Methods: Sixty-five persons with rheumatoid arthritis, age range 20-65 years, were invited to a clinical examination at 4 time-points during the 4 seasons. Outcome measures were: general fatigue rated on visual analogue scale (0-100) and aspects of fatigue assessed by the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire. Diseaserelated variables were: disease activity (erythrocyte sedimentation rate), pain threshold (pressure algometer), physical capacity (six-minute walk test), pain (visual analogue scale (0-100)), depressive mood (Hospital Anxiety and Depression scale, depression subscale), personal factors (age, sex, body mass index) and season. Multivariable regression analysis, linear mixed effects models were applied. Results: The strongest explanatory factors for all fatigue outcomes, when recorded at the same time-point as fatigue, were pain threshold and depressive mood. Self-reported pain was an explanatory factor for physical aspects of fatigue and body mass index contributed to explaining the consequences of fatigue on everyday living. For predicting later fatigue pain threshold and depressive mood were the strongest predictors. Conclusion: Pain threshold and depressive mood were the most important factors for fatigue in persons with rheumatoid arthritis.

    • Objectives: To describe self-reported activity using the Haemophilia Activity List (HAL) for Swedish adults with haemophilia and to detect any changes over time. Method: The HAL was sent to the adult population with haemophilia A and B, moderate and severe form, living in Sweden (n =260). Participants completed the HAL and a questionnaire on sociodemographic and medical information. From a previous study cohort, 61 persons had responded twice to the HAL. The investigated group was divided into early and later treatment onset groups with regard to access to medication. Results: The response rate was 50%. There was a significant difference (p<0.001) between the early and later treatment groups in all domains in HAL. When analysing HAL "question by question" from the 2 reported time-points, the most prominent outcome was that the reported ability in activities was stable over time at the group level, except for participants who had no access to the clotting factor early in life. They reported greater limitations in some of the activities in the challenging domain "leisure activities and sport". Conclusion: The early treatment group reported a significantly better ability in all activities compared with the late treatment group.

  • Automatic identification of construction candidates for a Swedish constructicon
  • 2013
  • Ingår i: Proceedings of the workshop on lexical semantic resources for NLP at NODALIDA 2013, May 22-24, 2013, Oslo, Norway. NEALT Proceedings Series 19. - 1650-3686 .- 1650-3740. ; s. 2-11
  • Konferensbidrag (refereegranskat)abstract
    • We present an experiment designed for extracting construction candidates for a Swedish constructicon from text corpora. We have explored the use of hybrid n-grams with the practical goal to discover previously undescribed partially schematic constructions. The experiment was successful, in that quite a few new constructions were discovered. The precision is low, but as a push-button tool for construction discovery, it has proven a valuable tool for the work on a Swedish constructicon.

    • Cognitive and mental deterioration, such as difficulties with memory and language, are some of the typical phenotypes for most neurodegenerative diseases including Alzheimer’s disease and other dementia forms. This paper describes the first phases of a project that aims at collecting various types of cognitive data, acquired from human subjects in order to study relationships among linguistic and extra-linguistic observations. The project’s aim is to identify, extract, process, correlate, evaluate, and disseminate various linguistic phenotypes and measurements and thus contribute with complementary knowledge in early diagnosis, monitor progression, or predict individuals at risk. In the near future, automatic analysis of these data will be used to extract various types of features for training, testing and evaluating automatic classifiers that could be used to differentiate individuals with mild symptoms of cognitive impairment from healthy, age-matched controls and identify possible indicators for the early detection of mild forms of cognitive impairment. Features will be extracted from audio recordings (speech signal), the transcription of the audio signals (text) and the raw eye-tracking data.

  • The effects of clinical supervision on supervisees and patients in cognitive behavioral therapy : a systematic review
  • 2018
  • Ingår i: Cognitive Behaviour Therapy. - 1650-6073 .- 1651-2316. ; 47:3, s. 206-228
  • Forskningsöversikt (refereegranskat)abstract
    • <p>Clinical supervision is a central part of psychotherapist training but the empirical support for specific supervision theories or features is unclear. The aims of this study were to systematically review the empirical research literature regarding the effects of clinical supervision on therapists’ competences and clinical outcomes within Cognitive Behavior Therapy (CBT). A comprehensive database search resulted in 4103 identified publications. Of these, 133 were scrutinized and in the end 5 studies were included in the review for data synthesis. The five studies were heterogeneous in scope and quality and only one provided firm empirical support for the positive effects of clinical supervision on therapists’ competence. The remaining four studies suffered from methodological weaknesses, but provided some preliminary support that clinical supervision may be beneficiary for novice therapists. No study could show benefits from supervision for patients. The research literature suggests that clinical supervision may have some potential effects on novice therapists’ competence compared to no supervision but the effects on clinical outcomes are still unclear. While bug-in-the-eye live supervision may be more effective than standard delayed supervision, the effects of specific supervision models or features are also unclear. There is a continued need for high-quality empirical studies on the effects of clinical supervision in psychotherapy.</p>

  • Evaluating the greenhouse gas impact from biomass gasification systems in industrial clusters – methodology and examples
  • 2011
  • Ingår i: Proceedings of World Renewable Energy Congress. - 1650-3686. - 978-91-7393-070-3 ; 12:057, s. 3098-3105
  • Konferensbidrag (refereegranskat)abstract
    • Biomass gasification is identified as one of the key technologies for producing biofuels for the transport sector and can also produce many other types of products. Biomass gasification systems are large-scale industrial systems and it is important to evaluate such systems from economic, environmental and synergetic perspectives before implementation. The objective of this study is to define a methodology for evaluating the greenhouse gas (GHG) impact of different biomass gasification systems and to exemplify the methodology. The ultimate purpose of the methodology is to evaluate the GHG performance of different biomass gasification systems integrated in industrial clusters. A life cycle perspective is applied.Most biomass gasification systems are multiproduct systems, simultaneously producing biofuels, heat at different temperatures and pressures and electricity. The value, in economic terms and in terms of GHG emissions, is well defined for some products (e.g. biofuels), whereas for other products (such as heat and electricity) it is more uncertain and in some cases dependent on time and location.
