- 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

- 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.

- 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.

- 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.

SELF-REPORTED ACTIVITY OF SWEDISH PERSONS WITH HAEMOPHILIA: CHANGE OVER 2.5 YEARS
- 2018

Tidskriftsartikel (refereegranskat)abstract
- 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

- 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.

Konferensbidrag (refereegranskat)abstract
- In this paper we provide a quantitative and qualitative analysis of meaning of allegedly non-gradable modal adjectives in different discourse contexts. The adjectives studied are essential, necessary, crucial and vital which are compared with a gradable modal adjective important. In our study sentences containing these adjectives were chosen from a large corpus together with their contexts. Then 120 English native speakers evaluated the meaning of these adjectives in a crowd-sourced study. Different types of contexts were chosen for this purpose. In some the adjectives were used as gradable with a modifier very while in others as non-gradable, without a modifier. We also modified the contexts by adding or removing the modifier very. The task for evaluators was to provide a replacement for adjectives for all the resulting contexts. From the replacements we are able to quantitatively evaluate the semantic potential of these contexts and what kind of adjectives they license.

Clinical supervision in cognitive behavior therapy improves therapists' competence : a single-case experimental pilot study
- 2020

Ingår i: Cognitive Behaviour Therapy. - : Informa UK Limited. - 1650-6073 .- 1651-2316. ; 49:5, s. 425-438

Tidskriftsartikel (refereegranskat)abstract
- Clinical supervision is a cornerstone in psychotherapists' training but there are few empirical evaluations on the effects of supervision on therapists' competencies. The aim of this study was therefore to evaluate the effects of standardized supervision on rater-assessed competency in Cognitive Behavior Therapy (CBT). Six therapists with basic training in CBT were provided with protocol-based clinical supervision in CBT in a single-case experimental multiple baseline design. The supervision focused on specific CBT competencies and used experiential learning methods such as role-play. Each therapist recorded weekly treatment sessions during phases without and with supervision. The therapists' CBT competence was assessed by third-party raters using the Revised Cognitive Therapy Scale (CTS-R). Statistical analyses showed that the therapists' CTS-R scores increased significantly during the phase with supervision with a mean item increase of M = 0.71 (range = 0.50-1.0) on the supervision focus areas. This is one of the first empirical studies that can confirm that supervision affect CBT competencies. The results also suggest that supervision can be manualized and that supervisees have a positive perception of more active training methods. Further studies are needed to replicate the results and to find ways to improve the impact of supervision.
