Molecular phylogenetics and taxonomic issues in dragonfly systematics (Insecta: Odonata)
- 2006
-
Doctoral thesis (other academic/artistic)abstract
- Dragonflies (Odonata) are one of the ancestral groups of extant insects. They represent one of the three most basal branches in the phylogeny of winged insects. The other two groups are the Ephemeroptera, mayflies, and Neoptera, the latter which covers the remaining winged insects. The first paper is about the phylogenetic position of Odonata in relation to the other basal insect clades using 18S and 28S rDNA sequences. It was demonstrated that there are under certain parameters a strong statistical support for a sister-group relationship between Odonata and Neoptera forming the group Palaeoptera. The second paper is about the phylogeny of the Holarctic dragonfly Leucorrhinia. Dragonfly larvae are frequently equipped with spines on the abdomen, with great variation in spinyness between species. From an analysis of sequences of ITS and 5.8S rDNA it was found that spines have been lost at least twice in Leucorrhinia, in the European L. rubicunda and again in a clade of North American species. The third paper is on the subfamily Ischnurinae (Odonata: Coenagrionidae), a group dominated by the two larger genera Ischnura and Enallagma along with several mono- or oligotypic genera. From the presented molecular study, using mitochondrial 16S rDNA and COII sequences, it is demonstrated that Ischnurinae, and Ischnura are monophyletic. Enallagma is not monophyletic, and the genus name Enallagma should be restricted to the E. cyathigerum clade. he fourth paper is a catalog of the genus Coenagrion, with full information on synonymy, type material and bibliographical data. The fifth paper is an appeal to the International Commission on Zoological Nomenclature to suppress the genus group name Agrion. The letter of appeal elucidates the priority of Agrion, and demonstrates why it has fallen out of use. A case if made for why Agrion should be placed on the list of unavailable names, and Calopteryx given full validity.

Towards Blended Reactive Planning and Acting using Behavior Trees
- 2019

In: 2019 International Conference on Robotics And Automation (ICRA). - : IEEE Robotics and Automation Society. - 9781538660263 ; , s. 8839-8845

Conference paper (peer-reviewed)abstract
- In this paper, we show how a planning algorithm can be used to automatically create and update a Behavior Tree (BT), controlling a robot in a dynamic environment. The planning part of the algorithm is based on the idea of back chaining. Starting from a goal condition we iteratively select actions to achieve that goal, and if those actions have unmet preconditions, they are extended with actions to achieve them in the same way. The fact that BTs are inherently modular and reactive makes the proposed solution blend acting and planning in a way that enables the robot to effectively react to external disturbances. If an external agent undoes an action the robot re- executes it without re-planning, and if an external agent helps the robot, it skips the corresponding actions, again without re- planning. We illustrate our approach in two different robotics scenarios.

The gut microbiota and metabolic disease: current understanding and future perspectives
- 2016

In: Journal of Internal Medicine. - : Wiley. - 0954-6820. ; 280:4, s. 339-349
-
Journal article (peer-reviewed)abstract
- The human gut microbiota has been studied for more than a century. However, of nonculture-based techniques exploiting next-generation sequencing for analysing the microbiota, development has renewed research within the field during the past decade. The observation that the gut microbiota, as an environmental factor, contributes to adiposity has further increased interest in the field. The human microbiota is affected by the diet, and macronutrients serve as substrates for many microbially produced metabolites, such as short-chain fatty acids and bile acids, that may modulate host metabolism. Obesity predisposes towards type 2 diabetes and cardiovascular disease. Recently, it has been established that levels of butyrate-producing bacteria are reduced in patients with type 2 diabetes, whereas levels of Lactobacillus sp. are increased. Recent data suggest that the reduced levels of butyrate-producing bacteria might be causally linked to type 2 diabetes. Bariatric surgery, which promotes long-term weight loss and diabetes remission, alters the gut microbiota in both mice and humans. Furthermore, by transferring the microbiota from postbariatric surgery patients to mice, it has been demonstrated that an altered microbiota may contribute to the improved metabolic phenotype following this intervention. Thus, greater understanding of alterations of the gut microbiota, in combination with dietary patterns, may provide insights into how the gut microbiota contributes to disease progression and whether it can be exploited as a novel diagnostic, prognostic and therapeutic target. © 2016 The Association for the Publication of the Journal of Internal Medicine

Interprofessional communication in a psychiatric outpatient unit – an ethnographic study
- 2023
-
In: BMC Nursing. - : BioMed Central Ltd. - 1472-6955. ; 22:1
-
Journal article (peer-reviewed)abstract
- Background: Communication in healthcare has been extensively studied, but most research has focused on miscommunication and the importance of communication for patient safety. Previous research on interprofessional communication has mainly focused on relationships between physicians and nurses in non-psychiatric settings. Since communication is one of the core competencies in psychiatric care, more research on interprofessional communication between other clinicians is needed, and should be explored from a broader perspective. This study aimed to explore and describe interprofessional communication in a psychiatric outpatient unit. Method: During spring 2022, data consisting of over 100 h of fieldwork were collected from observations, formal semi-structured interviews and informal conversations inspired by the focused ethnography method. Data was collected at an outpatient unit in central Sweden, and various clinicians participated in the study. The data analysis was a back-and-forth process between initial codes and emerging themes, but also cyclical as the data analysis process was ongoing and repeated and took place simultaneously with the data collection. Results: We found that a workplace’s history, clinicians´ workload, responsibilities and hierarchies influence interprofessional communication. The results showed that the prerequisites for interprofessional communication were created through the unit’s code of conduct, clear and engaging leadership, and trust in the ability of the various clinicians to perform new tasks. Conclusion: Our results indicate that leadership, an involving working style, and an environment where speaking up is encouraged and valued can foster interprofessional communication and respect for each other´s professional roles is key to achieving this. Interprofessional communication between different clinicians is an important part of psychiatric outpatient work, where efficiency, insufficient staffing and long patient queues are commonplace. Research can help shed light on these parts by highlighting aspects influencing communication.

Asymmetric Complex-Vector Models with Application to VSC-Grid Interaction
- 2020
-
In: IEEE Journal of Emerging and Selected Topics in Power Electronics. - 2168-6777 .- 2168-6785. ; 8:2, s. 1911-1921

Journal article (peer-reviewed)abstract
- The properties of complex space-vector models for asymmetric three-phase systems are investigated in this article. Most importantly, three alternative methods for the stability analysis of the asymmetric closed-loop systems are presented. The end results avoid the usage of matrix manipulations. It is shown how the theory can be applied to modeling and stability analysis of a grid-connected voltage-source converter (VSC). The methods are compared using numerical examples.

-
In: Beiträge empirischer Musikpädagogik. - 2190-3174. ; 6:1
-
Journal article (peer-reviewed)abstract
- This article presents a study investigating how a music teacher enables composition amongst high school students in a musical project. The main aim is to explore in what way the music teacher teach students to compose music and play in band in a musical project aiming to encourage students to create a musical and what tools for learning that are made visible in this process. A sociocultural and ethnomusicological approach was employed, drawing on field studies and interviews with the music teacher. The results demonstrate that the music teacher strongly influence the adolescents in their learning process and the teacher creates frames that the students can respond freely to, which makes the students secure and free at the same time. This approach from the music teacher enables a lot of compositions amongst his students.Key words: Composing, teaching, ethnomusicology, music education, sociocultural perspective.
