    Social organisation and breeding biology of the White-shouldered Fairywren (Malurus alboscapulatus)2019In: Emu (Print), ISSN 0158-4197, E-ISSN 1448-5540, Vol. 119, no 3, p. 274-285Article in journal (Refereed)
    Abstract [en]

    The White-shouldered Fairywren (Malurus alboscapulatus) is a tropical passerine bird distributed across much of New Guinea. White-shouldered Fairywrens are among few species of fairywren with exclusively tropical distributions and differ from better studied congeners in Australia because subspecies vary by female, but not male, coloration and morphology. As with many bird species in New Guinea, basic demographic, social, morphological, and breeding data are limited. From 2011 to 2018 we documented the basic biology of two subspecies representing extremes of the female ornamentation spectrum. Both subspecies form groups having an even operational sex ratio and appear to breed year-round. Extra-pair paternity occurs in the subspecies with female ornamentation; comparable data are lacking for the subspecies having unornamented females, but the greater scaled cloacal protuberance volume of males suggests similar or higher extra-pair paternity rates. Females of the ornamented subspecies are generally larger than those lacking ornamentation, but exhibit reduced tail lengths, which is thought to serve as a signal of social dominance in other fairywrens. After first achieving adult-like plumage, males and ornamented females retain ornamented plumage year-round; however, only males in the subspecies with unornamented females appear to exhibit delayed plumage maturation. Our discussion highlights similarities and differences between White-shouldered Fairywren life histories and those of better studied Australian Malurus species; we focus on tropical vs. temperate environments and variable female ornamentation, and we identify priorities for future research.

    Engagerat ledarskap för att skapa förutsättningar för allas delaktighet: Utgångspunkter i kvalitetsarbetet2019Doctoral thesis, monograph (Other academic)
    Abstract [en]

    According to increased demands on continuous improvements for organizations, they choose different strategies for improvements such as the use of systematic quality systems to structure the progresses in the business. However, studies have shown that improvement projects often fail due to the leadership and commitment within the organization. Research points out weak or missing techniques and tools connected to committed leadership and let everybody be committed, two important principles in systematic quality systems like Total Quality Management, in Sweden mentioned as the cornerstone model.

    Based on six different studies, this doctoral thesis deepens the knowledge about managers’ prerequisites to use leadership, which can enable commitment to an organization’s quality work in a Swedish context. First, five smaller studies were conducted, mainly focused on diversity, inclusion, and leadership in different kinds of organizations. The results from these five studies created a foundation for the sixth and main study, a case study within an organization dealing with Fast-Moving Consumer Goods. The case study included observations, both non-participation and participation, interviews with CEO, the management group, employees, but included also group measurement and document studies during a year with follow-up interviews.

    In conclusion, the doctoral thesis results have contributed to the development of techniques and tools connected to how a committed leadership can give prerequisites to let everybody be committed. The results have also given the possibility to complement the model Principles-Practices-Tools (PAV) with additional principles, concrete techniques and tools

    Phylogenetic analysis and embryonic expression of panarthropod Dmrt genes2019In: Frontiers in Zoology, ISSN 1742-9994, E-ISSN 1742-9994, Vol. 16, article id 23Article in journal (Refereed)
    Abstract [en]

    Background: One set of the developmentally important Doublesex and Male-abnormal-3 Related Transcription factors (Dmrt) is subject of intense research, because of their role in sex-determination and sexual differentiation. This likely non-monophyletic group of Dmrt genes is represented by the Drosophila melanogaster gene Doublesex (Dsx), the Caenorhabditis elegans Male-abnormal-3 (Mab-3) gene, and vertebrate Dmrt1 genes. However, other members of the Dmrt family are much less well studied, and in arthropods, including the model organism Drosophila melanogaster, data on these genes are virtually absent with respect to their embryonic expression and function.

    Results: Here we investigate the complete set of Dmrt genes in members of all main groups of Arthropoda and a member of Onychophora, extending our data to Panarthropoda as a whole. We confirm the presence of at least four families of Dmrt genes (including Dsx-like genes) in Panarthropoda and study their expression profiles during embryogenesis. Our work shows that the expression patterns of Dmrt11E, Dmrt93B, and Dmrt99B orthologs are highly conserved among panarthropods. Embryonic expression of Dsx-like genes, however, is more derived, likely as a result of neo-functionalization after duplication.

    Conclusions: Our data suggest deep homology of most of the panarthropod Dmrt genes with respect to their function that likely dates back to their last common ancestor. The function of Dsx and Dsx-like genes which are critical for sexual differentiation in animals, however, appears to be much less conserved.

    Twenty-three unsolved problems in hydrology (UPH) - a community perspective2019In: Hydrological Sciences Journal, ISSN 0262-6667, E-ISSN 2150-3435, Vol. 64, no 10, p. 1141-1158Article in journal (Refereed)
    Abstract [en]

    This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through online media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focused on the process-based understanding of hydrological variability and causality at all space and time scales. Increased attention to environmental change drives a new emphasis on understanding how change propagates across interfaces within the hydrological system and across disciplinary boundaries. In particular, the expansion of the human footprint raises a new set of questions related to human interactions with nature and water cycle feedbacks in the context of complex water management problems. We hope that this reflection and synthesis of the 23 unsolved problems in hydrology will help guide research efforts for some years to come.

    Regulation of docking and priming in pancreatic α- and β-cells2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The secretion of islet hormones from endocrine cells of the pancreas plays vital roles in maintaining glucose homeostasis. Dysfunction of these cells leads to diabetes, a devastating metabolic disorder affecting millions worldwide, but underlying mechanisms remain poorly understood. In hyperglycemic conditions, β-cells secrete insulin, whereas α-cells secrete an increased amount of glucagon in hypoglycemic conditions. Both insulin and glucagon are stored in secretory granules preceding their release by regulated exocytosis. This process involves several steps, including tethering, docking, priming, and finally, a fusion of the granules with the plasma membrane. Soluble N-ethylmaleimide–sensitive factor attachment protein receptor (SNARE) proteins and phosphoinositides (PIs) drive pancreatic hormone exocytosis and secretion, which follows a biphasic time course. Biphasic secretion is thought to reflect the vastly different release probabilities of individual granules, but direct evidence for this is still lacking.  Therefore, this thesis investigates exocytosis in the two main pancreatic cell types with a particular focus on preceding steps docking and priming, to identify rate-limiting steps in health and type-2 diabetes (T2D). Our data indicated that granule docking is critical for sustained secretion in α- and β-cells. Glucagon granule exocytosis had a U-shaped sensitivity to glucose in both healthy and T2D α-cells. However, T2D α-cells exhibited a marginal decrease in exocytosis, as well as docking, and they were markedly insensitive to somatostatin and insulin. T2D β-cells reduced exocytosis dramatically, and docking was compromised and no longer responsive to glucose, which correlated with reduced insulin secretion and elevated donor HbA1c. These results were further strengthened by the finding that expression of a group of genes that are involved explicitly in granule docking was reduced (by RNAseq of islets from over 200 human donors), and overexpression of the corresponding proteins increased granule docking in human β-cells.

    We further aimed to study the basis for the recruitment of these proteins to the docking site. Here we tested the hypothesis that highly charged lipids mainly PIs act as a hotspot to interact with SNARE proteins that initiate docking. We showed the homogenous distribution of all PIs markers in the plasma membrane, with no PIs microdomains at the exocytotic site during granule docking. However, rapid and local PI(4,5)P2 signaling at fusion sites was crucial for stabilizing fusion pore by binding to proteins related to the release site. These results suggested a role of PI(4,5)P2 in priming and fusion regulation rather than docking. Overall, this work gives new insights into the mechanisms underlying pancreatic hormone secretion in both healthy and diabetic conditions.

    Abstract [en]

    Glucose-stimulated insulin secretion is biphasic, with a rapid first phase and a slowly developing sustained second phase; both are disturbed in type 2 diabetes (T2D). Biphasic secretion results from vastly different release probabilities of individual insulin granules, but the morphological and molecular basis for this is unclear. Here, we show that human insulin secretion and exocytosis critically depend on the availability of membrane-docked granules and that T2D is associated with a strong reduction in granule docking. Glucose accelerated granule docking, and this effect was absent in T2D. Newly docked granules only slowly acquired release competence; this was regulated by major signaling pathways, but not glucose. Gene expression analysis indicated that key proteins involved in granule docking are downregulated in T2D, and overexpression of these proteins increased granule docking. The findings establish granule docking as an important glucose-dependent step in human insulin secretion that is dysregulated in T2D.

    Abstract [en]

    Phosphoinositides (PtdIns) play important roles in exocytosis and are thought to regulate secretory granule docking by co-clustering with the SNARE protein syntaxin to form a docking receptor in the plasma membrane. Here we tested this idea by high-resolution total internal reflection imaging of EGFP-labeled PtdIns markers or syntaxin-1 at secretory granule release sites in live insulin-secreting cells. In intact cells, PtdIns markers distributed evenly across the plasma membrane with no preference for granule docking sites. In contrast, syntaxin-1 was found clustered in the plasma membrane, mostly beneath docked granules. We also observed rapid accumulation of syntaxin-1 at sites where granules arrived to dock. Acute depletion of plasma membrane phosphatidylinositol (4,5) bisphosphate (PtdIns(4,5)P-2) by recruitment of a 5-phosphatase strongly inhibited Ca2+-dependent exocytosis, but had no effect on docked granules or the distribution and clustering of syntaxin-1. Cell permeabilization by -toxin or formaldehyde-fixation caused PtdIns marker to slowly cluster, in part near docked granules. In summary, our data indicate that PtdIns(4,5)P-2 accelerates granule priming, but challenge a role of PtdIns in secretory granule docking or clustering of syntaxin-1 at the release site.

    Public Art and Policy: Educating Library Users and Accidental Recidivists in Copyright Literacy2019In: Icepops Annual 2019: Proceedings of the International Copyright-literacy Event with Playful Opportunities for Practitioners and Scholars. Held at the University of Liverpool 3rd April 2018. / [ed] Secker, Jane; Morrison, Chris, London: UK Copyright Literacy , 2019, p. 44-45Conference paper (Other academic)
    Abstract [en]

    The paper describes a copyright literacy/art map project which had the initial purpose to educate library users and accidental recidivists in copyright literacy. While library users were the first target group (due to the public library event for which I created the map proto-types), the target group could most certainly be extended to the general public.

    The project takes the form of art maps published online with clear markings on whether the art object (statue, sculpture etc.) is selfie safe; i.e. whether it is possible to take a photograph which depicts the public art piece and then publish it in a database online (e.g. through social media).

    Skyddsinfiltrationens influensområde för en fallstudie: - modellering och osäkerheter2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    To evaluate the area of influence due to artificial infiltration several analytical models are available. Some of the parameters taken into account by these models are the hydraulic conductivity and storage coefficient, but with these models some assumptions, which in reality cannot be fulfilled, are made. An alternative approach to evaluate the area of influence is therefore with numerical models, which in a greater extent account for the site-specific conditions. Due to this, numerical models are more time consuming and require more input data.

    This project aims to investigate the most effective approaches to evaluate the area of influence due to artificial infiltration for a case study in Bromsten, located 15 kilometers northwest of Stockholm. Two numerical models, with different background data due to the extent of site knowledge, were developed to represent the site's geological settings and groundwater properties to simulate the groundwaterlevels with and without infiltration. Moreover the area of influence were calculated with four analytical models. All of the models were then applied on four different scenarios, in which the data resolution and the site knowledge increased. Site-specific data was added as a result of geological surveys and hydrogeological tests. The study also aims to answer which data is most important in order to determine the area of influence with analytical and numerical models and what differences there are between the analytical solutions compared with the numerical solutions.

    Among the methods investigated, constructing a more complex model with data from scenario 4, the scenario with the greatest data supply, resulted in the most reliable results and was therefore the best method and the method to choose for this case-study. Other results indicated that the numerical models first of all are sensitive to the conductivity and that the more simpel numerical model is sensitive to the storage coefficient as well. The last result shows that this model does not reach the steady state conditions as observed in field, which highlights the importance of goetechnical investigation for the numerical models. Moreover none of the numerical models were sensitive to the specific yield. Among the analytical models the storage coefficient was the most important followed by the conductivity. For one of the analytical models (Sichardts formula) the conductivity was the most sensitive parameter. The thickness of the aquifer had no significant impact on the analytical models.

    Vilken effekt har framtida klimat på strömningsmönster i Ekoln - en modelleringsstudie baserad på MIKE 3 FM2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    For centuries in the future, the climate on Earth will be affected by the global warming.Effects as melting ices, increasing sea levels and extreme weather, are all consequencesof the high amount of carbon dioxide (CO2), that we humans have caused. In Sweden,can climate effects like higher temperatures, longer vegetation periods and greaterseasonal variations in water fluxes, be expected. Due to climate changes and anincreasing population, the drinking water production in Uppsala will be affected. Interms of securing the drinking water production in the future, Uppsala Vatten och Avfall AB are investigating the possibility to use the Ekoln basin in lake Mälaren, as acomplementary raw water catchment area.

    In order to keep a secure drinking water production, in regard to quantity and quality, itis of interest to investigate how fluxes and water quality will be affected in the future.The annual pattern of water mixing, with summer- and winter stratification, and overturnduring spring and autumn, is something that significantly affects the water quality in theSwedish lakes. With the aim to study how the annual pattern of water mixing in theEkoln basin, might change due to future climate changes, hydrodynamic modelling wasperformed on a model area consisting of the Ekoln basin with adjacently bays.

    A hydrodynamic (3D) transport model of type MIKE 3 Flow Model FM, created byTyréns AB for simulating transport of pollutions, was calibrated and adapted to simulatetemperature profiles in the model area. To be able to study the annual pattern of watermixing, the model was also adapted to simulate a period of a year. Three scenarios weresimulated, one reference year and two future scenarios, where the future scenarios werebased on the climate scenarios RCP4.5 and RCP8.5 in year 2050.

    The calibration of the model was successful, and the calculation time was reduced byadapting the mesh. Results from the three scenarios, showed that the period with summerstratification might become nine days longer by RCP4.5 in year 2050, compared to thereference scenario. Simulation of RCP8.5 during the same time period, did not showany changes. By RCP8.5 it is possible that water temperatures in the epilimnion, areincreasing and that there will be no winter stratification. The temperature in the surfacewater are affected by the air temperature, in future studies it is in interest to investigatehow stratification and cirkulation will be affected by changes in wind speed and winddirection, how different types of wind data effect the results, it is also in interest to studychanges during a time period longer than one year.

    Nitrogen Uptake by Vegetation in the Wakkerstroom Wetland, South Africa2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The lack of proper wastewater treatment inhibits the social and economic development in many communities. The South African town Wakkerstroom is an example where wastewater is first treated before it is released. Due to the lack of technical expertise and funding to manage the sewage disposal system, a large part of the wastewater goes directly, without any treatment, into a stream feeding the Wakkerstroom wetland. The wetland purifies the wastewater and provides clean water downstream, thus is indispensable for its detoxification capacity.

    One relatively cheap method to determine the absorption capacity of a wetland with respect to nitrogen loading is to investigate the nitrogen uptake by the wetland vegetation. In this study, the nitrogen uptake of the vegetation in the Wakkerstroom wetland during the growing seasons between the years 2000-2018 was investigated by using harvested biomass and its nitrogen content as a proxy. The interannual variability of Net Primary Production (NPP) was calculated using a Light Use Efficiency (LUE) model for the period 2000-2018. The NPP derived with LUE-modelling was compared to NPP based on an end-of season harvest of biomass in March 2019. The nitrogen content and carbon and nitrogen (C:N) ratio were determined in the harvested biomass by carbon and nitrogen content analysis. The annual nitrogen uptake of the growing seasons between the years 2000-2018 was subsequently determined by multiplying the calculated NPP by the fraction of nitrogen found in the harvested material.

    The NPPtot based on harvested biomass (NPPharvest) towards the end of the growing season 2018/2019 was estimated to be 2.01 kg‧m-2‧season-1. The NPPtot calculated from LUE modelling (NPPLUE) varied between 0.49-1.64 kg‧m-2 for the growing seasons between 2000-2018. NPPharvest was between 1.2-4 times higher compared to NPPLUE, probably due to overestimation of NPPharvest because of biomass sampling of more than one-year production, or underestimation of NPPLUE due to a low maximum radiation conversion efficiency factor, εmax. The community mean nitrogen (N) content found in the biomass harvested aboveground was 1.29 % for the Phragmites community and 1.00 % for the Typha community. The nitrogen uptake of the vegetation was estimated to vary between 6.10-20.5 g N∙m-2 per growing season between the years 2000-2018.

    Do people actually listen to ads in podcasts?: A study about how machine learning can be used to gain insight in listening behaviour2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today, listening to podcasts is a common way of consuming media and it has been proven that listeners are much more recipient to advertisement when being addressed in a podcast, rather than through radio. This study has been performed at Acast, an audio-on-demand and podcast platform that hosts, monetizes, and distributes podcasts globally. With the use of machine learning, the goal of this study has been to obtain a credible estimate of how listeners outside the application tend to respond when exposed to ads in podcasts. The study includes a number of different machine learning models, such as Random Forest, Logistic Regression, Neural Networks and kNN. It was shown that machine learning could be applied to obtain a credible estimate of how ads are received outside the Acast application, based on data collected from the application. Additionally, out of the models included in the study, Random Forest was proven being the best performing model for this problem. Please note that the results presented in the report are based on a mix of real and simulated data.

    Democratic Consolidation: Thailand’s attempt at democracy2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this dissertation was to examine the process of democratic consolidation in Thailand between 1997-2006.  The country’s consolidation of democracy has been hampered by continuous cycle of coup d’états which throughout history have halted the overall process of democratization. The coup of 2006 is one example of those instances where the democratic consolidation process was interrupted.

     

    The method used to examine the years of 1997-2006 was theory consuming by qualitative text analysis where the data used to assess the situation was qualitative. The theory of democratic consolidation was offered by Juan J. Linz and Alfred Stepan. The theory’s prerequisites were applied to examine the case study of Thailand. The theory chosen were hoped to give a plausible explanation for the failure of democratic consolidation in the case of Thailand. It was also hoped that it could assess the overall quality of Thai democracy and possibly give a better insight in why military coups seem to be a reoccurring phenomenon in the case of Thailand.

    Elit och tvång, eller släkt och rådslag?: Två tolkningar av makten på Gotland under romersk järnålder2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the archaeological research about the Baltic Sea island of Gotland during Roman Iron Age, 0–400 AD, two different approaches are visible: One that sees the community life on Gotland as different from the one on the main land with a relative stabile development, based on the family and kin, where no higher elite separate itself. The other perception emanates from the changes in southern Scandinavia, where an elite steadily grows and finally isolate itself as an aristocracy with unlimited power over others, the development on Gotland is no exception.

    This paper is about describing, investigating and explaining these two points of view. By using a selection of written sources the paper tries to answer three questions: What archaeological argumentations are there for that Gotland should be particular? What support the views that the island was a part of an over-regional development when it comes to struggle for power? What lies behind these very diverse positions among archaeological scholars?

    Two scholars, Kerstin Cassel and Frands Herschend, represents the two opposite standpoints and the three questions are to be answered by a comparison with two of their main archaeological works. This comparison, based on the other written sources and my own understanding, will show that the two different views on the gotlandish development can be traced to, more than anything, the two writers pre-understanding of their own scientific argumentations.

    Hillefors grynkvarn: En studie i industriell arkitektur2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här uppsatsen är en studie i industriell arkitektur och då specifikt Hillefors grynkvarn. Mitt syfte är ta reda på hur den exteriöra arkitekturen har anpassats och formats efter kvarnens inre verksamhet och geografiska läge. Den industrianläggning jag fokuserar på är kvarnen byggd i tegel 1913, tillbyggd 1929 och 1940, fram till dess att den industriella verksamheten avslutades 1987. Anledningen till mitt val av ämne är att industribyggnader icke placerade i storstadsområde ofta inte är dokumenterade i samma utsträckning. Den metod som använts är empirisk forskning på plats för att undersöka kvarnens placering i terrängen, exteriöra respektive interiöra utformning samt dess maskinpark. Arkiv-och litteraturstudier har genomförts. Resultatet och analysen av mitt arbete visar på att Hillefors grynkvarns placering i terrängen samt exteriöra arkitektur har formats efter dess inre verksamhet. Havregrynstillverkningen kräver ett uppfordringsverk som innebär att utrymme uppåt måste finnas. Kvarnens placering vid ett stup ner mot Säveån har gjort det möjligt att bygga sutteräng i fyra våningar vilket verksamheten var i behov av. Havren levererades av bönder vid våning fyra och föll succesivt via magasin ner i byggnaden för att sedan genom uppfodringsverket transporteras uppåt via remtransmisson. Kraften att driva kvarnens turbiner kom från Säveån via en vattenränna.

    Culture in motion: Material culture in the inventory of Catherine Jagiellon’s dowry from 1562 and its analysis from culture transfer perspective2019Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    On the 4th of October 1562, the Polish princess Catherine Jagiellon married the Swedish prince and duke of Finland Johan Vasa. Leaving Poland, Catherine Jagiellon was equipped with a very rich dowry and followed by an entourage of nearly 50 people. The objective of this study is to investigate the objects and people surrounding the newly wedded 16th century princess and asses if the document mirrors the complex cultural interactions of the early modern world. The analysis of the inventory is carried out using two theoretical approaches: material culture and culture transfer. The study is constructed in two parts. The first part focuses on the analysis of the sections of the inventory following the order of the document. If possible, the objects are mapped, their history is traced through the sources, their appearance and function are discussed. The examination of the members of the court is also carried out. With the deepened analysis of the inventory as a basis, the second part of the study is dedicated to the search of culture hybridization markers in described artefacts, people, practices as well as the language of the document itself. With the result of this investigation, the author is able to pinpoint the complex international cultural processes that were occurring in an early modern world.

    Syftet med denna studie har varit att undersöka förhållandet mellan den svenska hembygdsrörelsen och länsmuseerna, för att ta reda på om det finns ett fungerande samarbete mellan dem, vad samarbetet innefattar, hur attityderna gentemot samarbete är och om länsmuseerna har något formellt ansvar för att bedriva samarbete med hembygdsrörelsen. Studien har genomförts huvudsakligen genom litteraturstudier samt två enkätundersökningar och presenterar resultat för varje län i Sverige. De genomförda undersökningarna har visat på att det i varje län generellt finns välfungerande samarbeten av någon omfattning mellan de båda parterna. Samarbetena kretsar kring ett antal olika områden såsom vanligtvis rådgivning, kursverksamhet, projekt, administration med mera. Attityderna till samarbete uppfattas från båda parter generellt vara goda, de anser att de kan komplettera varandra och gemensamt kan dra nytta av välfungerande samarbeten. Länsmuseerna har inget formellt ansvar för att samverka med hembygdsrörelsen men det finns ett antal dokument som uttrycker att samarbete är önskvärt och bör eftersträvas.

    Confident phylogenetic identification of uncultured prokaryotes through long read amplicon sequencing of the 16S-ITS-23S rRNA operon2019In: Environmental Microbiology, ISSN 1462-2912, E-ISSN 1462-2920, Vol. 21, no 7, p. 2485-2498Article in journal (Refereed)
    Abstract [en]

    Amplicon sequencing of the 16S rRNA gene is the predominant method to quantify microbial compositions and to discover novel lineages. However, traditional short amplicons often do not contain enough information to confidently resolve their phylogeny. Here we present a cost-effective protocol that amplifies a large part of the rRNA operon and sequences the amplicons with PacBio technology. We tested our method on a mock community and developed a read-curation pipeline that reduces the overall read error rate to 0.18%. Applying our method on four environmental samples, we captured near full-length rRNA operon amplicons from a large diversity of prokaryotes. The method operated at moderately high-throughput (22286-37,850 raw ccs reads) and generated a large amount of putative novel archaeal 23S rRNA gene sequences compared to the archaeal SILVA database. These long amplicons allowed for higher resolution during taxonomic classification by means of long (similar to 1000 bp) 16S rRNA gene fragments and for substantially more confident phylogenies by means of combined near full-length 16S and 23S rRNA gene sequences, compared to shorter traditional amplicons (250 bp of the 16S rRNA gene). We recommend our method to those who wish to cost-effectively and confidently estimate the phylogenetic diversity of prokaryotes in environmental samples at high throughput.

    Exhausted Women, Exhausted Welfare and the Role of Religion2019In: Social Inclusion, ISSN 2183-2803, E-ISSN 2183-2803, Vol. 7, no 2, p. 1-3Article in journal (Other academic)
    Abstract [en]

    This themed collection is bound together by some foundational observations which have been well documented in earlier research. European post-war welfare systems face challenges related to aging populations, globalization, migration, changing patterns of family and gender roles. The post-war model of welfare dependent on the idea of stable heterosexual families, with male breadwinners and women carers is giving way to more individualized and mobile systems. The four articles and commentary in this issue provide glimpses of the issues within this field that unite contexts as diverse as the Nordic countries, Brazil and the United States. They explore the intersection of welfare, religion and gender charting gendered problems in welfare provision in relation to religious organisation, affiliation and identity. This issue provides examples of how the exhaustion of women and welfare systems is interconnected and the understanding of this crucial to any attempts to reform welfare systems to enhance social inclusion or reduce exclusion.

    A laboratory-based double X-ray spectrometer for simultaneous X-ray emission and X-ray absorption studies2019In: Journal of Analytical Atomic Spectrometry, ISSN 0267-9477, E-ISSN 1364-5544, Vol. 34, no 7, p. 1409-1415Article in journal (Refereed)
    Abstract [en]

    X-ray spectroscopy studies are usually performed using synchrotron radiation sources, which offer bright, coherent, energy-tuneable and monochromatic light. However, the application of synchrotron-based Xray emission spectroscopy (XES) and X-ray absorption spectroscopy (XAS) is directly constrained by the limited, infrequent access to central facilities. With the advent of new technological solutions in the field of X-ray sources, optics and detectors, the development of efficient and compact laboratory X-ray spectroscopy systems is possible. A permanent laboratory-based setup offers the advantages of low cost and easy accessibility and, therefore, more flexibility in the preparation and scheduling of measurements. Herein, we report a laboratory X-ray setup allowing simultaneous XES and XAS measurements. The double von Hamos spectrometer performances are demonstrated by concurrent K beta XES and K-edge XAS measurements done for 3d elements.

    Grazing and warming effects on shrub growth and plant species composition in subalpine dry tundra: An experimental approach2019In: Journal of Vegetation Science, ISSN 1100-9233, E-ISSN 1654-1103, Vol. 30, no 4, p. 698-708Article in journal (Refereed)
    Abstract [en]

    Questions

    Vegetation in the forest–tundra ecotone faces changes in both climate and land‐use. While climate warming is an important driver of vegetation growth and composition, herbivory may have opposing effects. In the present study, we experimentally test how removal of sheep herbivory affects the vegetation in an alpine forest–tundra ecotone, and how responses are manifested at higher temperatures.

    Location

    Dovre Mountains, Central Norway.

    Methods

    Shrub growth (height and cover) and ground layer composition were analysed each third year over an 18‐year period in a nested, three‐factorial experiment (ambient temperature and herbivory; ambient temperature and no herbivory; increased temperature and no herbivory). Fencing and open‐top‐chambers were used as expedients. Treatment effects and interactions over time were analysed using linear mixed effects models and ordination.

    Results

    Shrub height and cover increased over time due to reduced herbivory, but without additional warming effect. Lichen cover declined in all treatments over time, but more rapidly and earlier under warming treatment (significant after three years). Contrary to expectations, there was no statistically significant increase in woody species due to warming, although evergreen woody species displayed a trend shift after six years, comprising a sharp decline towards year twelve. Litter accumulated in all treatments, but at higher rates under warming (significant after nine years).

    Conclusions

    Our results disclose removal of sheep herbivory as a prominent driver of shrub growth, with warming as a subordinate driver in the studied alpine vegetation. The warming‐driven increased litter abundance may, however, be caused by the decrease of wind inside chambers and the subsequent absence of wind‐driven removal of litter. This chamber effect and the displayed timing differences in vegetation responses call for the critical use of short‐term experimental data in predictions of long‐term consequences of environmental change.

    How does toxicity change depending on rank in League of Legends?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to investigate toxic remarks in three different ranks in League of Legends, Bronze, Gold, and Diamond. The purpose is to understand how toxic communication between players would change depending on rank. A framework from Neto, Alvino and Becker (2018) was adopted to define and count toxic remarks. The method relied on participant observation to gather data; three different ranks were specified for data collection. Fifteen games were played in each of the ranks; Bronze, Gold, and Diamond. Each game was recorded, transcribed and analyzed by dividing each toxic remark registered into Neto, Alvino and Becker’s predetermined categories. The study concluded that domain language is more often used by players with a higher rank, meaning that high ranked players tend to use toxicity that requires previous game knowledge to understand. On the contrary, low ranked players tend to stick to basic complaints and insults when using toxicity to remark teammates while playing.

    Game or watch: The effect of interactivity on arousal and immersion in horror game media2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of the study was to determine if interactivity would affect how immersed and aroused the participants would become when exposed to horror media with different levels of interactivity. Two groups of participants were asked to either play or watch a virtual scenario. The participants had their heart rate measured using an activity bracelet and eyes tracked using a Tobii 4C eye tracker. The study found that as interactivity increased, so did arousal, whilst immersion did not. The results indicated that cutscenes may result in significantly lower levels of arousal, compared to interactive gameplay.

    How Do Different DLC Delivery Methods Impact Appeal and Effectiveness2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Downloadable content (DLC) distribution models employ various methods to keep consumers interested. Some methods encourage consumers to purchase and engage with a DLC model and some methods discourage consumers from engaging with the model. This study seeks to determine which models keep consumers interested and which discourage consumers from purchasing DLC. We do this by reaching out to multiplayer communities of four different games that are affected by different models and have them fill out a survey regarding their purchasing behaviour. After analysing the results, we concluded that models that require players to own the same DLC in order to play together or that utilize watermarks for DLC that are not owned, are less effective at incentivizing players to purchase when compared to models that either allow players to share DLC, or acquire it through in-game means.

    Turismens utsläpp på Gotland2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The tourism industry is accounted for high monetary revenues but is also responsible for a high amount of emissions globally. In this study the emissions from the tourism sector are discussed with a special focus on the Swedish island, Gotland. Because Gotland is an island there are limited ways to travel to the island. There are generally three ways to get to the island, by ferry, airplane or by a cruise ship. Approximately 70% of the tourists travel by ferry and it is therefore the focus of this study. In this study emissions from tourism were calculated by the travel to and from the island, and during the stay. Emissions from transport on the island to various destinations were calculated as well as emissions from accommodations. The result from the study shows that the tourism on Gotland has far lower emissions than the general global tourism. This is mostly due to the low emissions from the electric production in Sweden.

    Summary Statistic Selection with Reinforcement Learning2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Multi-armed bandit (MAB) algorithms could be used to select a subset of the k most informative summary statistics, from a pool of m possible summary statistics, by reformulating the subset selection problem as a MAB problem. This is suggested by experiments that tested five MAB algorithms (Direct, Halving, SAR, OCBA-m, and Racing) on the reformulated problem and comparing the results to two established subset selection algorithms (Minimizing Entropy and Approximate Sufficiency). The MAB algorithms yielded errors at par with the established methods, but in only a fraction of the time. Establishing MAB algorithms as a new standard for summary statistics subset selection could therefore save numerous scientists substantial amounts of time when selecting summary statistics for approximate bayesian computation.

    Sphagnum limits: Physiology, morphology and climate2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Sphagnum is the most important plant genus in terms of terrestrial carbon cycling. It and the habitats it creates store an equivalent of ~68% of the CO2 in the atmosphere. The genus has little dispersal limitation and the mire habitats are functionally similar at global scales. Sphagnum species are limited by water deficit at local and biogeographic scales, but this alone is not sufficient to explain local and global scale species patterns. As Sphagnum shoots are long-lived they may be limited by stochastic periods of cold temperature. Within Europe, species are associated with climate gradients along north-south (cold-warm) and oceanic-continental (wet-dry) clines. Within mires, species are sorted along a moisture (hummock-hollow) gradient.

    In this thesis I examined species responses to and recovery from freezing (I). I compared species with different water level niches in traits related to water management of individual shoots and colonies (II). Using distribution modelling of GBIF data, I estimated how different aspects of climate contributed to Sphagnum species distributions in Europe (III). Combining the approaches in papers II and III, I modelled the climatic distributions of the parapatric species S. cuspidatum and S. lindbergii and assessed how traits of water economy varied across the distribution boundary (IV).

    Species responses to winter stress were largely allied to both their hydrological niche and geographic range. Generally, hollow species managed better than hummock species, but species from intermediate positions were less consistent in their response. Species associated with boreal regions were generally less affected than those from temperate regions. Hardening against low temperature was triggered by shorter days and cold nights. Cold temperatures during late autumn may be more important for Sphagnum limits than the minimum temperature during winter.

    Water-related traits split the species into two groups; hollows species with large capitula and hummock species with small capitula. However, inter- and intra-specific trait variation and trait trends along the hydrological gradient were not necessarily the same at the shoot and canopy scale. Some trait correlations were common to all species. Canopy traits, which were emergent traits of colonies of shoots, had the strongest trait associations with the species position along the hummock-hollow gradient.

    At the continental scale the distribution of most Sphagnum species could be successfully modelled by a combination of annual degree days and water balance and the degree of seasonality in these two variables. Individual species distributions were shaped more by the seasonality in degree days than in water balance.

    Across the distributional border of S. cuspidatum and S. lindbergii divergence in the measured traits was mostly seen in the capitula indicating that limits to Sphagnum species are strongly linked to the functioning of the capitulum. Capitulum mass of both species was lower in sympatry than in allopatry, even though the measured values were similar. Canopy traits most strongly separated the species though did not change across the species boundaries.

    In summary, Sphagnum species in general are limited by the availability of water. Low temperature, particularly during late autumn are probably decisive for the biogeographic limits and for the distribution of species along the hydrological gradient.

    Ridsportens miljö- och klimatpåverkan: Miljöarbete bland Sveriges ridklubbar2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Our society is facing challenges from a changing climate and environmental issues, which makes it important for everyone to take action for a better future. Equestrian sports, one of Sweden’s biggest sports, also have a part to play. The Swedish Equestrian Federation has a sustainability and environmental strategy since 2016, and seeks to continuously improve their environmental work. The present study aims to investigate how riding clubs work with two out of five sections presented in the strategy: Education and Operational management of stables. Impact from equestrian activities includes the six categories fodder, manure handling, electricity comsumption, transportation, horse and rider equipment. and chemicals, which, in this study are linked to Sweden’s environmental objective. It is clear that horses and stabling have significant impact on both the nearby environment and is a contributing factor to global warming, though the level of impact ranges depending on the type of actions taken to reduce the ecological footprint. A survey was conducted to find out how the Swedish riding associations works with environmental and climate issues, including education and the operational management of the categories listed above. The main finding in the survey is a communication gap between the Swedish Equestrian Federation and the riding associations, as well as a lack of knowledge of the environmental and climate impact from equestrian activities.

    Spellagens påverkan på aktiekurser: En eventstudie om huruvida beviljandet av spellicens har en positiv påverkan på spelbolagens aktier2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den svenska riksdagen röstade 2018-06-07 ja till regeringens förslag om en ny spellag. Den nya spellagen innebär bland annat införandet av ett licenssystem för spelbolag verksamma på den svenska spelmarknaden. Denna studie undersöker huruvida nyheter om beviljade licenser leder till positiv avkastning hos spelbolagens aktier. För att undersöka effekten av nyheterna utförs en eventstudie med licensierade spelbolag på den svenska och norska aktiemarknaden. Eventstudien undersöker eventfönster som består av en, fem, tio och tjugo dagar där signifikansen testas genom ett t-test. Resultaten visar att den kumulativa genomsnittliga abnormala avkastningen är signifikant för eventfönster med längd av en dag, men icke-signifikant för eventfönster med längd av fem, tio och tjugo dagar.

    Genome-Wide Analysis of Long Non-Coding RNA Profiles in Canine Oral Melanomas2019In: Genes, ISSN 2073-4425, E-ISSN 2073-4425, Vol. 10, no 6, article id 477Article in journal (Refereed)
    Abstract [en]

    Mucosal melanomas (MM) are rare aggressive cancers in humans, and one of the most common forms of oral cancers in dogs. Similar biological and histological features are shared between MM in both species, making dogs a powerful model for comparative oncology studies of melanomas. Although exome sequencing recently identified recurrent coding mutations in canine MM, little is known about changes in non-coding gene expression, and more particularly, in canine long non-coding RNAs (lncRNAs), which are commonly dysregulated in human cancers. Here, we sampled a large cohort (n = 52) of canine normal/tumor oral MM from three predisposed breeds (poodles, Labrador retrievers, and golden retrievers), and used deep transcriptome sequencing to identify more than 400 differentially expressed (DE) lncRNAs. We further prioritized candidate lncRNAs by comparative genomic analysis to pinpoint 26 dog-human conserved DE lncRNAs, including SOX21-AS, ZEB2-AS, and CASC15 lncRNAs. Using unsupervised co-expression network analysis with coding genes, we inferred the potential functions of the DE lncRNAs, suggesting associations with cancer-related genes, cell cycle, and carbohydrate metabolism Gene Ontology (GO) terms. Finally, we exploited our multi-breed design to identify DE lncRNAs within breeds. This study provides a unique transcriptomic resource for studying oral melanoma in dogs, and highlights lncRNAs that may potentially be diagnostic or therapeutic targets for human and veterinary medicine.

    BarkBase: Epigenomic Annotation of Canine Genomes2019In: Genes, ISSN 2073-4425, E-ISSN 2073-4425, Vol. 10, no 6, article id 433Article in journal (Refereed)
    Abstract [en]

    Dogs are an unparalleled natural model for investigating the genetics of health and disease, particularly for complex diseases like cancer. Comprehensive genomic annotation of regulatory elements active in healthy canine tissues is crucial both for identifying candidate causal variants and for designing functional studies needed to translate genetic associations into disease insight. Currently, canine geneticists rely primarily on annotations of the human or mouse genome that have been remapped to dog, an approach that misses dog-specific features. Here, we describe BarkBase, a canine epigenomic resource available at barkbase.org. BarkBase hosts data for 27 adult tissue types, with biological replicates, and for one sample of up to five tissues sampled at each of four carefully staged embryonic time points. RNA sequencing is complemented with whole genome sequencing and with assay for transposase-accessible chromatin using sequencing (ATAC-seq), which identifies open chromatin regions. By including replicates, we can more confidently discern tissue-specific transcripts and assess differential gene expression between tissues and timepoints. By offering data in easy-to-use file formats, through a visual browser modeled on similar genomic resources for human, BarkBase introduces a powerful new resource to support comparative studies in dogs and humans.

    Unprecedented reorganization of holocentric chromosomes provides insights into the enigma of lepidopteran chromosome evolution2019In: Science Advances, E-ISSN 2375-2548, Vol. 5, no 6, article id eaau3648Article in journal (Refereed)
    Abstract [en]

    Chromosome evolution presents an enigma in the mega-diverse Lepidoptera. Most species exhibit constrained chromosome evolution with nearly identical haploid chromosome counts and chromosome-level gene collinearity among species more than 140 million years divergent. However, a few species possess radically inflated chromosomal counts due to extensive fission and fusion events. To address this enigma of constraint in the face of an exceptional ability to change, we investigated an unprecedented reorganization of the standard lepidopteran chromosome structure in the green-veined white butterfly (Pieris napi). We find that gene content in P. napi has been extensively rearranged in large collinear blocks, which until now have been masked by a haploid chromosome number close to the lepidopteran average. We observe that ancient chromosome ends have been maintained and collinear blocks are enriched for functionally related genes suggesting both a mechanism and a possible role for selection in determining the boundaries of these genome-wide rearrangements.

    Abstract [en]

    During the last couple of years, an increasing number of teachers have chosen to leave their profession in the world of teaching. There a number of reasons as to why teachers are leaving their current employment; some teachers describe their administrative workload being overwhelming whilst others state that the general responsibility at the workplace has increased. In addition, some teachers declare that the general workload also has increased. Nowadays there is a lack of educated teachers, approximately around 60 000 vacant posts need to be filled in the Swedish school-system. In a school, located in the south of Sweden, there has been a large shift of employees. There has been a large number of teachers, who have been on sick leave or left their employment voluntarily. In a pre-study, made in the spring of 2019, which this essay is based on, ambiguities were identified in regard to the job description and the division of responsibility, in the teaching profession. In order to carry out the study of this essay, a case study with an abductive approach was chosen to investigate the factors behind the problems previously mentioned, in the previously mentioned a south-Swedish school. The premise of the study was to present different factors which influence and support the teachers’ mission. The intention of the essay was to identify and map factors which can promote mission- and responsibility-comprehension in the school.  To enable the essay and the study, the following questions were used: Which factors are hindering the teachers’ mission- and responsibility comprehension? and Which factors create mission- and responsibility comprehension?. To understand the teachers’ challenges in everyday tasks and discover possible factors that are influencing the teachers’ mission, the author of the essay has studied results which previous research has produced. The collection of data is a qualitative data collection method consisting of observations of teachers as well as individual with the teachers. In chapter 4, results, the results of the observation-schedule and the teachers’ dictums are presented. The factors which obstructed the teachers in their daily work were (1) Digitalized communication, (2) Confidence and honesty between staff, (3) Lack of cooperation between colleagues, (4) The meeting’s agenda, which took time from the teachers’ work, (5) The lack of leadership and (6) The teachers’ working methods. The factors which promoted mission- and responsibility comprehension were (1) The teachers’ comprehension of their mission, (2) The structure of the meetings, in the shape of a scheduled day and time for the meeting, (3) The motivation and dedication the teachers feel for their job as well as (4) The willingness to cooperate between teachers. To create better opportunities for mission- and responsibility comprehension, a PDSA-cycle was presented for the continuation of the work improvement for the school.

    Cancer therapy and risk of congenital malformations in children fathered by men treated for testicular germ-cell cancer: A nationwide register study2019In: PLoS Medicine, ISSN 1549-1277, E-ISSN 1549-1676, Vol. 16, no 6, article id e1002816Article in journal (Refereed)
    Abstract [en]

    Background Because of the potential mutagenic effects of chemo- and radiotherapy, there is concern regarding increased risk of congenital malformations (CMs) among children of fathers with cancer. Previous register studies indicate increased CM risk among children conceived after paternal cancer but lack data on oncological treatment. Increased CM risk was recently reported in children born before paternal cancer. This study aims to investigate whether anti-neoplastic treatment for testicular germ-cell cancer (TGCC) implies additional CM risk. Methods and findings In this nationwide register study, all singletons born in Sweden 1994-2014 (n = 2,027,997) were included. Paternal TGCC diagnoses (n = 2,380), anti-neoplastic treatment, and offspring CMs were gathered from the Swedish Norwegian Testicular Cancer Group (SWENOTECA) and the Swedish Medical Birth Register. Children were grouped based on +/- paternal TGCC; treatment regimen: surveillance (n = 1,340), chemotherapy (n = 2,533), or radiotherapy (n = 360); and according to time of conception: pre- (n = 2,770) or post-treatment (n = 1,437). Odds ratios (ORs) for CMs were calculated using logistic regression with adjustment for parental ages, maternal body mass index (BMI), and maternal smoking. Children conceived before a specific treatment acted as reference for children conceived after the same treatment. Among children fathered by men with TGCC (n = 4,207), 184 had a CM. The risk of malformations was higher among children of fathers with TGCC compared with children fathered by men without TGCC (OR 1.28, 95% confidence interval [CI] 1.19-1.38, p = 0.001, 4.4% versus 3.5%). However, no additional risk increase was associated with oncological treatment when comparing post-treatment-to pretreatment-conceived children (chemotherapy, OR = 0.82, 95% CI 0.54-1.25, p = 0.37, 4.1% versus 4.6%; radiotherapy, OR = 1.01, 95% CI 0.25-4.12, p = 0.98, 3.2% versus 3.0%). Study limitations include lack of data on use of cryopreserved or donor sperm and on seminoma patients for the period 1995-2000-both tending to decrease the difference between the groups with TGCC and without TGCC. Furthermore, the power of analyses on chemotherapy intensity and radiotherapy was limited. Conclusions No additional increased risk of CMs was observed in children of men with TGCC treated with radio- or chemotherapy. However, paternal TGCC per se was associated with modestly increased risk for offspring malformations. Clinically, this information can reassure concerned patients.

    Nature-Based Interventions for Improving Health and Wellbeing: The Purpose, the People and the Outcomes2019In: SPORTS, ISSN 2075-4663, Vol. 7, no 6, article id 141Article in journal (Refereed)
    Abstract [en]

    Engagement with nature is an important part of many people's lives, and the health and wellbeing benefits of nature-based activities are becoming increasingly recognised across disciplines from city planning to medicine. Despite this, urbanisation, challenges of modern life and environmental degradation are leading to a reduction in both the quantity and the quality of nature experiences. Nature-based health interventions (NBIs) can facilitate behavioural change through a somewhat structured promotion of nature-based experiences and, in doing so, promote improved physical, mental and social health and wellbeing. We conducted a Delphi expert elicitation process with 19 experts from seven countries (all named authors on this paper) to identify the different forms that such interventions take, the potential health outcomes and the target beneficiaries. In total, 27 NBIs were identified, aiming to prevent illness, promote wellbeing and treat specific physical, mental or social health and wellbeing conditions. These interventions were broadly categorized into those that change the environment in which people live, work, learn, recreate or heal (for example, the provision of gardens in hospitals or parks in cities) and those that change behaviour (for example, engaging people through organized programmes or other activities). We also noted the range of factors (such as socioeconomic variation) that will inevitably influence the extent to which these interventions succeed. We conclude with a call for research to identify the drivers influencing the effectiveness of NBIs in enhancing health and wellbeing.

    Effects of cladribine tablets on heart rate, atrio-ventricular conduction and cardiac repolarization in patients with relapsing multiple sclerosis2019In: British Journal of Clinical Pharmacology, ISSN 0306-5251, E-ISSN 1365-2125, Vol. 85, no 7, p. 1484-1494Article in journal (Refereed)
    Abstract [en]

    Aims Cladribine tablets have shown significant efficacy for the treatment of relapsing multiple sclerosis, a chronic and debilitating immune-mediated disorder. This study was conducted to examine acute and/or cumulative effects of cladribine tablets 10 mg (3.5 or 5.25 mg/kg cumulative dose over 2 years) on heart rate, AV conduction and cardiac repolarization in patients with relapsing-remitting multiple sclerosis (RRMS). Methods CLARITY was a 96-week, double-blind, placebo-controlled, multicentre trial which evaluated the safety and efficacy of cladribine tablets 3.5 and 5.25 mg/kg body weight in patients with RRMS. A total of 135 patients were included in the ECG substudy, providing a total of 1534 post-dose ECGs. ECG data were collected 15 minutes pre-dose and between 0.5 and 3 hours post-dose at pre-study evaluation, study Day 1 and Weeks 5, 9, 13, 48 and 52. Results For cladribine tablets 3.5 mg/kg, the maximum change in placebo-adjusted post-dose QTcF vs. visit-baseline (BL) was -0.42 ms (90% CI: -3.61-4.44) at Week 1 (acute effects), and 3.20 ms (90% CI: -0.08-6.33) for cladribine tablets 5.25 mg/kg. The greatest observed differences in post-dose QTcF vs. study BL occurred at Week 48 for both the 3.5 and 5.25 mg/kg doses of cladribine tablets with 5.99 ms (90% CI: 0.53-11.44) and 8.74 ms (90% CI: 3.18-14.31), respectively. No significant changes were observed in T-wave morphology in either treatment group. Conclusions Cladribine tablets 3.5 mg/kg (approved dose in Europe/other regions) did not confer clinically meaningful effects on heart rate, AV conduction and ventricular repolarization.

    Embryonic expression of priapulid Wnt genes2019In: Development, Genes and Evolution, ISSN 0949-944X, E-ISSN 1432-041X, Vol. 229, no 4, p. 125-135Article in journal (Refereed)
    Abstract [en]

    Posterior elongation of the developing embryo is a common feature of animal development. One group of genes that is involved in posterior elongation is represented by the Wnt genes, secreted glycoprotein ligands that signal to specific receptors on neighbouring cells and thereby establish cell-to-cell communication. In segmented animals such as annelids and arthropods, Wnt signalling is also likely involved in segment border formation and regionalisation of the segments. Priapulids represent unsegmented worms that are distantly related to arthropods. Despite their interesting phylogenetic position and their importance for the understanding of ecdysozoan evolution, priapulids still represent a highly underinvestigated group of animals. Here, we study the embryonic expression patterns of the complete sets of Wnt genes in the priapulids Priapulus caudatus and Halicryptus spinulosus. We find that both priapulids possess a complete set of 12 Wnt genes. At least in Priapulus, most of these genes are expressed in and around the posterior-located blastopore and thus likely play a role in posterior elongation. Together with previous work on the expression of other genetic factors such as caudal and even-skipped, this suggests that posterior elongation in priapulids is under control of the same (or very similar) conserved gene regulatory network as in arthropods.

    Transcriptomic analysis reveals cell apoptotic signature modified by heparanase in melanoma cells2019In: Journal of Cellular and Molecular Medicine (Print), ISSN 1582-1838, E-ISSN 1582-4934, Vol. 23, no 7, p. 4559-4568Article in journal (Refereed)
    Abstract [en]

    Heparanase has been implicated in many pathological conditions, especially inflammation and cancer, attributed to its degradation of heparan sulfate, a crucial component maintaining the integrity of the extracellular matrix. By silencing the heparanase gene (HPSE) in MDA-MB-435s melanoma cells, we investigated the impact of this protein on gene transcription. Transcriptome sequencing yielded a list of 279 differentially expressed genes, of which 140 were up-regulated and 239 down-regulated. The 140 up-regulated genes were classified into a substantial set of gene ontology defined functions, for example, positive regulation of cell death, apoptotic process, response to cytokine, while 239 down-regulated genes classify only into the two categories: nucleosome and nucleosome assembly. Our focus was drawn to an array of 28 pro-apoptotic genes regulated by heparanase: real-time PCR experiments further validated up-regulation of EGR1, TXNIP, AXL, CYR61, LIMS2 and TNFRSF12A by at least 1.5-fold, among which EGR1, CYR61, and TNFRSF12A were confirmed on protein level. We demonstrated significantly increased apoptotic cells by TUNEL staining upon HPSE silencing, mediated by activation of caspase 3/PARP1 pathway. The pro-apoptotic gene expression and observation of apoptosis were extended to another melanoma cell line, MV3 cells, thus consolidating the anti-apoptosis effect of heparanase in melanoma cells.

    Copper-containing hybrid compounds based on extremely rare [V2Mo6O26]6- POM as water oxidation catalysts2019In: INORGANIC CHEMISTRY FRONTIERS, ISSN 2052-1553, Vol. 6, no 7, p. 1813-1823Article in journal (Refereed)
    Abstract [en]

    Herein, we report two approaches to the synthesis of heterometallic complexes (NH4)(2n)(H(2)en)(n){[Cu(en)(2)][alpha-V2Mo6O26]}center dot 4nH(2)O (1), (NH4)(2){[Cu(dien)(H2O)](2)[alpha-V2Mo6O26]}center dot 5H(2)O (2) and (NH4)(2){[Cu(dien)(H2O)](2)[alpha-V2Mo6O26]}center dot 8H(2)O (3) that have been employed in homogeneous photochemical oxidation of water to dioxygen. In these hybrid metalorganic-inorganic compounds, copper-containing complex fragments are covalently bound to the rare vanadium-disubstituted alpha-octamolybdate cluster. They exhibit variable catalytic activity controlled by the local coordination environment of copper reaching a notably high turnover frequency of 0.24 s(-1) for 3 in combination with a relatively low water oxidation overpotential. The complexes have been also used as precursors for the preparation of mixed oxide phases that have proven to be active heterogeneous water oxidation catalysts.

    The Association of Maternal Age With Fetal Growth and Newborn Measures: The Mumbai Maternal Nutrition Project (MMNP)2019In: Reproductive Sciences, ISSN 1933-7191, E-ISSN 1933-7205, Vol. 26, no 7, p. 918-927Article in journal (Refereed)
    Abstract [en]

    Background: Young maternal age is associated with poorer birth outcomes, but the mechanisms are incompletely understood. Using data from a prospective cohort of pregnant women living in Mumbai slums, India, we tested whether lower maternal age was associated with adverse fetal growth.

    Methods: Fetal crown-rump length (CRL) was recorded at a median (interquartile range, IQR) of 10 weeks' gestation (9-10 weeks). Head circumference (HC), biparietal diameter (BPD), femur length (FL), and abdominal circumference (AC) were recorded at 19 (19-20) and 29 (28-30) weeks. Newborns were measured at a median (IQR) of 2 days (1-3 days) from delivery. Gestation was assessed using prospectively collected menstrual period dates.

    Results: The sample comprised 1653 singleton fetuses without major congenital abnormalities, of whom 1360 had newborn measurements. Fetuses of younger mothers had smaller CRL (0.01 standard deviation [SD] per year of maternal age; 95% confidence interval CI: 0.00-0.02(1); P = .04), and smaller HC, FL, and AC at subsequent visits. Fetal growth of HC (0.04 cm; 95% CI: 0.02-0.05; P < .001), BPD (0.01 cm; 95% CI: 0.00-0.01; P = .009), FL (0.04 cm; 95% CI: 0.02-0.06; P < .001), and AC (0.01 cm; 95% CI: 0.00-0.01; P = .003) up to the third trimester increased with maternal age. Skinfolds, head, and mid-upper arm circumferences were smaller in newborns of younger mothers. Adjusting for maternal prepregnancy socioeconomic status, body mass index, height, and parity attenuated the associations between maternal age and newborn size but did not change those with fetal biometry.

    Conclusion: Fetuses of younger mothers were smaller from the first trimester onward and grew slower, independently of known confounding factors.

    Förbättringsarbete inom den offentliga sektorn: Rekryteringsprocessen och dess ansvarsfördelning2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study aims to gain an understanding of how the seasonal recruitment and division of responsibilities within the Resource Team at Region Gotland currently established in order to find opportunities for improvement in the process. The study is based on two questions of aim, "How do the seasonal recruitment and the division of responsibilities currently look like?" And "How can the seasonal recruitment process be developed?". The data material has been collected through qualitative methods in the form of interviews, observations of the daily operations and provision of internal documents. The material shows that there are certain ambiguities when it comes to seasonal recruitment in its entirety, and also when it comes to the distribution of responsibility among the employees, whereas there is uncertainty who is responsible for the different activities in the process. The problem that can arise in the case of an ambiguous division of responsibility is that employees do not know what is expected of them in their work roles, which can result in tasks not being performed. To develop and hopefully improve the seasonal recruitment process, a visualization of the process is inspired by the model for process charts, blueprinting. The Resource Team should clarify the division of responsibilities associated with the seasonal recruitment as some activities currently have no one in charge. It is advised and proposed that the Resource Team should create a work role in order to delegate the responsibilities in case of absence.

    Arbetsplatslärande: En fallstudie om ledningsarbete inom upplärningsprocessen.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The concept of competence summarizes requirements for knowledge and skills that are required for individuals, companies, organisations and nations to function effectively and in a timely manner. The growth of the service society in parallel with today’s rapid knowledge and technology development and increased processional competition has resulted in competence becoming a central concept in education and management. The development has meant a greater focus on external efficiency (to do the right things), which means that human performance, competence, nowadays are a prerequisite for delivering value to the customer.

    The improvement has been carried out at Liseberg which is one of Sweden’s most visited tourist destinations. The work has been delimited to the housing department and the working group reception. The reception is one of three working groups that are active in the department and is responsible for the guest’s stay at Liseberg’s residential facilities, Lisebergsbyn and Askim Stand. Before the improvement, a preliminary study was carried out that identified improvement possibilities in the training process of new employees to the reception. The preliminary study showed a great variation in the result and the experience of the execution of the training, which was considered an urgent improvement as the department is driven by human performance.

    Therefore, the aim of the improvement has been to improve the training process within the workgroup reception by clarifying working techniques and ensuring competence. Investigations of the present education process, how the work techniques can be clarified and how the competence can be ensured have been used to achieve the aim of the study.

    The result indicates that the working group has a common understanding of what needs to be taught and why it is important, however when and how a work task should be taught. The training process is currently not process-focused or defined, among other things, lacking management processes completely, which explains the employees’ experience of lack of structure and focus. The process function in such a way, as allowing the responsible managers to plan the work process themselves. The results also show that the managers’ motivation and self-confidence to their own competence to carry out the work with the process are varied.

    The study concludes that the training process needs to be process-focused, have management processes and add a supervisor course to the existing support process to ensure the necessary competence needed, as well as unifying and clarifying the working techniques. The working group also needs to clarify roles and expectations linked to the process’s activities and apply situational based management to the operative part of the process.

    Determining shallow P-wave velocity and its engineering implication in Adama City, Ethiopia2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A great number of the urban areas in Ethiopia are situated within the Great Rift Valley of Ethiopia, a system consisting of depressions and large faults. As a region with significant seismic activities, it is vital that careful planning is implemented to avoid constructing buildings on flat surfaces as they can amplify ground motion in the case of an earthquake.

     

    This study was conducted in Adama, a city located within the rift system, to map and characterize the subsurface of a construction site with seismic refraction and investigate whether this is an optimal area to construct a building should an earthquake occur. Seismic refraction is based on Snell’s law, specifically the case of the critical angle, which is when the refracted angle is at 90 degrees and a number of the energy from the wave is rebounded back to the surface in accordance with Huygen’s Principle.    

     

    Seismic waves were generated with a sledgehammer and recorded with 24 vertical geophones. The acquired data was then analysed with SeisImager and produced a 2D-tomography of the site with the corresponding velocity layers for a P-wave. Comparing the P-wave velocities to a table of Seismic Velocities of Rocks and Various Materials, one could determine that the subsurface layers consisted of rock soils, sand and silt. These are incredibly loose materials that will amplify ground motion during earthquake crisis and are therefore not optimal or ideal for constructing buildings.

    Development of measurement algorithm in an industrial PLC: An evaluation of DSOGI-PLL for real time measurements2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this project was to devise an algorithm for three phase AC power grid measurements that could be utilized in an excitation system for controlling generators. This application requires fast and accurate measurements even when the voltages in the power grid are characterized by unbalanced three-phase, frequency variations and harmonic distortions. Phase locked loop algorithms are used in grid synchronization techniques and are developed to withstand disturbances in the power grid. A DSOGI-PLL was implemented on a PLC and then evaluated. The DSOGI-PLL was tested with input voltages generated by a relay testing system. The result showed that the DSOGI-PLL could measure positive sequence component RMS and grid frequency of unbalanced three-phase voltages and voltages characterized by frequency variations and harmonic distortions. However, the measurements response time and accuracy did not meet the requirements for application in excitation systems.
