Konferensbidrag (refereegranskat)abstract
- This year’s iteration of the SIGMORPHON Shared Task on morphological reinflection focuses on typological diversity and cross- lingual variation of morphosyntactic features. In terms of the task, we enrich UniMorph with new data for 32 languages from 13 language families, with most of them be- ing under-resourced: Kunwinjku, Classical Syriac, Arabic (Modern Standard, Egyptian, Gulf), Hebrew, Amharic, Aymara, Magahi, Braj, Kurdish (Central, Northern, Southern), Polish, Karelian, Livvi, Ludic, Veps, Võro, Evenki, Xibe, Tuvan, Sakha, Turkish, In- donesian, Kodi, Seneca, Asháninka, Yanesha, Chukchi, Itelmen, Eibela. We evaluate six systems on the new data and conduct an extensive error analysis of the systems’ predictions. Transformer-based models generally demonstrate superior performance on the majority of languages, achieving >90% accuracy on 65% of them. The languages on which systems yielded low accuracy are mainly underresourced, with a limited amount of data. Most errors made by the systems are due to allomorphy, honorificity, and form variation. In addition, we observe that systems especially struggle to inflect multiword lemmas. The systems also produce misspelled forms or end up in repetitive loops (e.g., RNN-based models). Finally, we report a large drop in systems’ performance on previously unseen lemmas.

Ingår i: Medical Image Computing and Computer Assisted Intervention : MICCAI 2019 - 22nd International Conference, Proceedings - MICCAI 2019 - 22nd International Conference, Proceedings. - Cham : Springer International Publishing. - 1611-3349 .- 0302-9743. - 9783030322441 - 9783030322458 ; 11765 LNCS, s. 355-363

- The procedure of aligning a positron emission tomography (PET) image with a common coordinate system, spatial normalization, typically demands a corresponding structural magnetic resonance (MR) image. However, MR imaging is not always available or feasible for the subject, which calls for enabling spatial normalization without MR, MR-less spatial normalization. In this work, we propose a template-free approach to MR-less spatial normalization for [18F]flortaucipir tau PET images. We use a deep neural network that estimates an aligning transformation from the PET input image, and outputs the spatially normalized image as well as the parameterized transformation. In order to do so, the proposed network iteratively estimates a set of rigid and affine transformations by means of convolutional neural network regressors as well as spatial transformer layers. The network is trained and validated on 199 tau PET volumes with corresponding ground truth transformations, and tested on two different datasets. The proposed method shows competitive performance in terms of registration accuracy as well as speed, and compares favourably to previously published results.

Newly Graduated Nurses' Learning Work Climate, Health, Resilience, and Burnout Symptoms
- 2020

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The results provide an indication of important learning work climate factors associated to newly graduated nurses’ health, ability to cope successfully in adverse circumstances (i.e., resilience), and burnout symptoms. It is, however, plausible that there is an interconnection between personal vulnerability, learning climate, and health (Stoyanov & Cloninger, 2011).

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: To study genotype-phenotype correlations in genes encoding complex I electron input module subunits. Materials and methods: We studied five patients with isolated complex I deficiency, three with NDUFS1 mutations and two with NDUFV1 mutations. A literature review of all reported cases of mutations in the affected genes was performed. Results: The literature review revealed pathological mutations in NDUFS1 for 18 patients in 17 families and correspondingly in NDUFV1 for 26 patients in 19 families. Unpublished clinical data for our five patients were added. Our study showed quite variable clinical courses; death before two years of age was seen in 41% of patients while 18% were alive at seven years. There was a significant difference between the NDUFS1 and NDUFV1 groups for clinical onset and life-span. Mutations in NDUFS1 were linked to a worse clinical course with earlier onset and earlier death. Conclusions: Genotype-phenotype correlations in patients with mutations affecting the genes that encode the electron input module of complex I vary, but patients with NDUFS1 mutation tend to have a worse clinical course than patients with NDUFV1 mutation. Identifying the mutations is of importance for accurate prognostic information and genetic counseling.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In recent years Sweden had an increased number of asylum seekers entering the country. Asylum seeking can affect the physical and mental health of individuals due to prolonged application processes and waiting times which can lead to inactivity. Physical inactivity is one of the leading risk factors leading to noncommunicable diseases and overall mortality. The Public Health Report Blekinge 2014 states that groups with low socioeconomic status are less likely to be physically active in comparison with groups with a high socioeconomic status. Physical activity contributes to physical and mental well-being, and increases the possibilities for creating social networks as well as being part of the society. The project “Health for Everybody” (Hälsa för Alla) offers physical and cultural activities to approximately 300 refugees who have been granted asylum in the Blekinge region. The activities are conducted with the help of physical trainers, testing staff and community workers. In its current format each group of 20 to 30 refugees is offered training once a week for a 10-week period. The participants’ physical and psychological health and lifestyle habits are measured before and after the program through bioimpedance, physical conditioning tests and self-reports of psychological aspects related to health and lifestyle. We examined the health effects of cultural activities and Well-Being Coaching among long-term unemployed Swedish young adults. While individuals receiving cultural activities only showed a slight decrease in anxiety, those receiving Well-Being Coaching showed significant increases in subjective well-being and decreases in depression, anxiety, and sense of defeat and entrapment.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Personal vulnerability (i.e., specific personality profiles) is a major factor for burnout among helping professionals. Compared to the general population, 80% of Swedish newly graduated nurses reported high Reward Dependence (i.e., being sentimental, warm, attached, and dependent) and 95% reported low Self-Directedness (i.e., being blaming, aimless, helpless, defensive, and unfulfilled).

Well-Being Coaching Training: Character, Resilience and Well-Being
- 2018

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: The level of stress in the 21st century is increasing the risk for lifestyle and stress-related illness in all populations, including health care professionals who have the double burden of their personal problems and those of their patients. Between 2009 and 2014, psychiatric diagnoses, including burnout, have doubled in health care populations like nurses, doctors, and psychotherapists [1]. In order to help others, health care professionals have the need of a variety of tools and approaches to work on their own resilience, health, and well-being. The Anthropedia Foundation in collaboration with the Center for Well-Being at Washington University in St. Louis developed a specialized training that is person-centered, interdisciplinary, and biopsychosocial in orientation. This training can be integrated into existing professions or used independently. The training program has been designed to increase three character dimensions (self-directedness, cooperativeness, and self-transcendence) that have been shown to lead to increases in physical and mental health, resilience, and overall well-being [2-4]. Aim: The purpose of this study was to investigate whether well-being training was effective in increasing character scores in the training participants. Method: 50 trainees were given the Positive and Negative Affect Schedule, the Satisfaction with Life Scale, and the Temperament and Character Inventory before and after the one-year training. Paired t-tests were performed to examine significant differences. Results: Analyses showed significant differences in the Temperament and Character Inventory subscales of self-acceptance (t = 2.2, df = 49, p < .05, Cohen’s D = 0.77), empathy (t = 2.6, df = 49, p < .05, Cohen’s D = 0.90), moral reasoning (t = 3.17, df = 49, p < .01, Cohen’s D = 1.11), and the scale of self-transcendence (t = 2.98, df = 49, p < .01, Cohen’s D = 1.04). There was a marginal increase in positive emotions (t = 1.18, df = 49, p < .05) and life satisfaction (t = 1.57, df = 49, p < .05), and a marginal decrease in negative emotions (t = 1.26, df = 49, p < .05). Conclusions: Results suggest that the training methodology increased subjective well-being, as well as self-directedness (self-acceptance), cooperativeness (empathy and moral reasoning), and self-transcendence. Cross-cultural studies on these character dimensions have demonstrated strong relationships between increases in character development and perceived social support, perceived health, and resilience [2-4]. In other words, the well-being coaching training increases sustainable global health, resilience and psychological well-being, and not simply hedonic well-being. The coaching is more intensive since it is one-on-one, thus we expect the effect on subjective well-being and character to be even greater for coachees.
