Self‐directed learning using computer simulations to study veterinary physiology: Comparing individual and collaborative learning approaches
Authors: López‐Úbeda Rebeca , García‐Vázquez Francisco A. 
Published: May 2022

AbstractBackgroundAdvances in technology enable new educational resources geared towards situated learning and leading students to a more active education. Self‐directed learning methodologies used along with simulators may represent a good alternative to traditional teaching methods. The aims of this study were to analyse veterinary students' degree of acceptance of self‐directed learning using the PhysioEx simulator in physiology, and to evaluate self‐directed learning outcomes using different approaches (individual vs. collaborative).MethodsThe study was carried out over three academic years. Students conducted different activities on the PhysioEx simulator, either in an individual or cooperative mode. Once the activities were finished, students voluntarily participated in an opinion survey regarding self‐directed learning methodology. Finally, an evaluation of learning outcomes was made through Kahoot!.ResultsStudents expressed a high degree of satisfaction with this self‐directed learning method, with the combination of self‐directed learning and gamification being scored the highest. Although students prefer the collaborative method, no differences in learning outcomes were found between the two learning approaches.ConclusionThe self‐directed learning method in combination with gamification increased the motivation of students, who obtained suitable learning outcomes regardless of whether an individual or collaborative approach was followed.
Introduction
Authors: Luby Stephen , Southern Dorothy L. 
Published: May 2022

AbstractScientific writing is an essential skill for researchers. Scientific writing develops critical thinking, connects scientists’ results to global understanding, and identifies appropriate next questions to explore. However, there are several barriers to publishing: a lack of focus in framing the research question, difficulty in explaining why the study is important, inexperience in interpreting data and drawing out its implications, unfamiliarity with the requirements of scientific writing formats, and a lack of clarity and conciseness in the use of English language. The pathway to publishing describes a step-by-step process for early career researchers to progressively develop their scientific ideas into research projects and manuscripts that can be published in the international peer-reviewed literature.
General Research and Writing Practices
Authors: Luby Stephen , Southern Dorothy L. 
Published: May 2022

AbstractPublished articles contribute to ongoing conversations among scientists. To participate in this conversation, authors structure their manuscript in a standard format so that readers can quickly understand it. Articles deploy scientific arguments that build on and connect with other published work. Persuasive scientific reasoning requires that authors be familiar with relevant published work and cite it using a standard format so that readers can follow the development of the ideas that led to the authors’ manuscript. Plagiarism, presenting other people’s work as your own, is a particularly egregious error that can end your scientific career and so needs to be scrupulously avoided by careful and consistent citation. Scientific reasoning is exacting. Several lines of argument that are common in casual conversation or journalism embed errors in reasoning that scientific authors should recognize and avoid.
Slide and Poster Presentations
Authors: Luby Stephen , Southern Dorothy L. 
Published: May 2022

AbstractPresenting scientific work in a verbal presentation supplemented with slides or as a poster presentation is a valuable way to disseminate your work and to receive feedback that can be helpful in framing a manuscript. Slide and poster presentations emphasize visual communication. Avoid mind-numbing bulleted statements that provide a detailed outline that the presenter reads. Instead, consider how to communicate your ideas visually, how to illustrate the problem that the work engages, how you addressed it, and what you found. Steps you can take to improve your visual presentations include avoiding distracting chart junk and common distracting chart features like three-dimensional figures that do not provide any additional information in the third dimension or using a vertical bar chart that squeezes the title for each bar to the point that it is difficult to read. Clear presentations invite audience engagement and more useful feedback on your work.
The Spatialities of the Nordic Compact City
Authors: Røe Per Gunnar , Kjærås Kristin Edith Abrahamsen , Haarstad Håvard 
Published: May 2022

AbstractThe compact city has become the preferred and mainstream model for urban, peri-urban and sometimes even rural planning in the Nordic context. However, the compact city is increasingly contested as a model for sustainability and may be criticized for a functionalistic perspective on social practices and transitions. Besides, the compact city model is part of increasing transnational or global urban policy mobilities including generic models and strategies, and it may be argued that this contributes to the de-contextualisation of urban planning and development. In this chapter we scrutinize the spatialities of the compact city model and examine how the compact city model has played out in the Nordic context – focusing in particular on Oslo. We ask: how is the compact city developed and promoted as a spatial model? We argue that although the compact city has to some extent been promoted in influential policy circles as a universal model, the compact city in Oslo has some distinct features shaped by the Nordic context. In particular, these features can be attributed to welfare state governance centred on the public sector, yet it is also here we find some of the most significant differences between the Nordic countries. In closing, we discuss whether there is such a thing as a Nordic compact city model, and point to some of its political, social and cultural implications. Is there a pathway for a re-contextualized, relational and grounded compact city model?
Spatial Justice and Social Reproduction in the Nordic Periphery
Authors: Eriksson Madeleine , Tollefsen Aina 
Published: May 2022

AbstractIn this chapter we discuss how demands for social justice and struggles around social reproduction have evolved in the Nordic “periphery”, placing the struggles within a context of critical socio-spatial theorizing and earlier geographical research on uneven development within Nordic welfare states. We give examples from Sweden of how resistance in the northern periphery increasingly mobilizes around spatial justice and social reproduction rather than mainly around employment. Demands about the right to spatial justice challenge the rewarding of a specific place – usually the urban – of modernity, meaning-making and hub for democracy and resistance. And thus oppose the naturalization of uneven rual-urban geographies. Nordic critical geographers have researched inequalities within Nordic welfare states, including center-periphery divides and conflicts, and examined how these have increased with welfare state retrenchment. Feminist geographers highlight the centrality of battles around social reproduction – the right to environmental security, work, food, housing, healthcare, education, a meaningful and dignified life in both urban and rural places. We identify a tradition of empirically based geographical research on material conditions and changing socio-spatial forms of production and consumption, which suggests a socio-spatial theory useful in an era of crisis and increased privatization of nature and social reproduction.
Sublimated Expansionism? Living Space Ideas in Nordic Small-State Geopolitics
Authors: Larsen Henrik Gutzon , Marklund Carl 
Published: May 2022

AbstractIn intellectual histories of geography as well as in international relations, geopolitics is usually the business of great powers, understood as the expansion of hard power through territorial control. However, the existence of a ‘Geopolitik of the weak’ has also been theorised, premised on the ability of smaller states – such as the Nordic countries – to secure their survival through a wider range of policy instruments. In this chapter, we analyse key themes in the work of two Nordic geographical thinkers deeply concerned with the place and status of their home countries in the era of high modernity – Rudolf Kjellén and Gudmund Hatt. Relying upon their scholarly works as well as relevant public debates circa 1905–1945, we trace the ‘small-state geopoliticking’ of Hatt and Kjellén, identifying three key characteristics of their style of small-state geopolitics: (1) determinism is qualified by voluntarism; (2) space is complemented by future; and (3) external expansion is sublimated into internal progress. In its reconceptualisation of living space as primarily concerned with existential survival as premised upon future progress, rather than outward-oriented territorial expansion, small-state geopolitics emerges as a highly situated, somewhat quaint but nonetheless significant element in Nordic theorising of geography.
In Search of Nordic Landscape Geography: Tensions, Combinations and Relations
Authors: Germundsson Tomas , Jönsson Erik , Setten Gunhild 
Published: May 2022

AbstractThrough tracing what ‘landscape’ has meant, and the political and intellectual work that ‘landscape’ does, we in this chapter explore the shifting nature of Nordic landscape geography. We thereby aim to introduce readers to the role of the landscape concept within Nordic scholarship and critically engage with contemporary debates over the nature and meaning of landscape. Landscape was an important political concept long before the advent of geography as a discipline in the Nordic countries, though what landscape denoted differed between various national and linguistic settings. Based in our mapping of the concept as it has evolved within geography and related disciplines, we centre on three strands of landscape scholarship today: mediations on a particularly ‘Nordic’ substantive landscape concept, attempts to utilise landscape as a concept to influence planning, and attempts to utilise landscape as a concept to grasp environmental issues. Scrutinising these current traditions leads us to primarily underline the necessity of relational approaches to steer the concept away from a problematic and narrow emphasis on the local scale. Yet, and importantly, various relational approaches take analysis in different directions, leading us to also underscore the necessity of critically scrutinising where particular relational approaches might lead landscape geography.
Economic Geography of Innovation and Regional Development
Authors: Asheim Bjørn T. , Hansen Høgni Kalsø , Isaksen Arne 
Published: May 2022

AbstractResearch in economic geography on innovation and regional development is an important and thriving research area in Scandinavia, which has contributed significantly to theoretical and empirical advancements beyond the Scandinavian research environments. This chapter demonstrates how the field has developed and changed its focus over the years, touching upon and developing around central academic and societal topics from deindustrialisation, clusters and regional innovation systems to creativity, green transition and changing regional development paths. The chapter focuses on how research milieus have developed in Scandinavia, how theories, methodologies and methods have advanced and how researchers have worked together nationally and internationally during the last four decades.
QuoteKG: A Multilingual Knowledge Graph of Quotes
Authors: Kuculo Tin , Gottschalk Simon , Demidova Elena 
Published: May 2022

AbstractQuotes of public figures can mark turning points in history. A quote can explain its originator’s actions, foreshadowing political or personal decisions and revealing character traits. Impactful quotes cross language barriers and influence the general population’s reaction to specific stances, always facing the risk of being misattributed or taken out of context. The provision of a cross-lingual knowledge graph of quotes that establishes the authenticity of quotes and their contexts is of great importance to allow the exploration of the lives of important people as well as topics from the perspective of what was actually said. In this paper, we present QuoteKG, the first multilingual knowledge graph of quotes. We propose the QuoteKG creation pipeline that extracts quotes from Wikiquote, a free and collaboratively created collection of quotes in many languages, and aligns different mentions of the same quote. QuoteKG includes nearly one million quotes in 55 languages, said by more than 69, 000 people of public interest across a wide range of topics. QuoteKG is publicly available and can be accessed via a SPARQL endpoint.
Anästhesie bei einer thoraxchirurgischen Patientin mit kongenitaler Muskeldystrophie Typ Ullrich
Authors: Hachenberg Thomas , Walles Thorsten , Lücke Eva , Schilling Thomas 
Published: May 2022

ZusammenfassungDie kongenitale Muskeldystrophie Typ Ullrich (UCMD) ist eine seltene Erkrankung. Weltweit wurden bislang 50 Fälle genetisch gesichert. Autosomal-dominante und rezessive Mutationen des COL6A1/COL6A2 im Chromosom 21q22.3 oder des COL6A3 im Chromosom 2q37.3 führen zu einem Mangel an Kollagen VI. Typische Merkmale der UCMD sind Muskelschwäche von Körperstamm und Extremitäten, Hyperflexibilität der distalen und Kontrakturen der proximalen Gelenke, Rollstuhlpflichtigkeit im Alter von 9 bis 11 Jahren, Versteifung und Skoliose der Wirbelsäule und eine progrediente restriktive Ventilationsstörung. Etwa 50 % der Kinder benötigen im Alter von 11 bis 12 Jahren eine nichtinvasive Ventilation (NIV), wozu auch eine gestörte Funktion des Diaphragmas beiträgt. Es wird über die Narkose bei einer 21-jährigen Patientin mit einer UCMD berichtet, die seit dem 6. Lebensjahr rollstuhlpflichtig war und bei der seit 2018 eine lebenserhaltene NIV erfolgte. Wegen einer subpleuralen Einblutung in den linken Lungenunterlappen nach Entlastung eines Pneumothorax wurde eine videoassistierte thorakoskopische Chirurgie (VATS) vorgenommen. Die spezifischen Anforderungen durch die UCMD, das Atemwegsmanagement für die Einlungenventilation sowie Aspekte zur Auswahl der Anästhetika werden diskutiert. Nach erfolgreicher VATS konnte die Patientin am 7. postoperativen Tag in die Häuslichkeit entlassen werden.
Can the evolution of joint savings agreements counter the effect of higher costs of migration on its intensity?
Authors: Stark Oded , Jakubek Marcin 
Published: May 2022

AbstractIn this paper we consider a population of would-be migrants in a developing country. To begin with, this population is divided into two sets: those who save by themselves to pay for the cost of their migration, and those who pool their savings with the savings of another would-be migrant to pay for the cost. Saving jointly brings forward the timing of migration: funds needed to pay for the migration of one of the co-savers can be accumulated more quickly, enabling him, using his higher income at destination than at origin, to speed up the migration of his co-saver. However, people may hesitate to save jointly for fear that a co-saver who is the first to migrate might fail to keep his part of the agreement. We show that an increase in the cost of migration stimulates the formation of co-financing, joint-saving arrangements that enable would-be migrants to cushion the impact of the increase. The evolution of joint-saving arrangements can create a time window during which the intensity of migration need not decrease: no fewer people (and conceivably even more of them) will migrate during a time interval that follows the increase in the cost. This prediction is at variance with the canonical economic model of migration according to which if migration is costlier, then there will be less of it.
Simultaneous 18F-FDG-PET/MRI for the detection of periprosthetic joint infections after knee or hip arthroplasty: a prospective feasibility study
Authors: Henkelmann Jeanette , Henkelmann Ralf , Denecke Timm , Zajonz Dirk , Roth Andreas , Sabri Osama , Purz Sandra 
Published: May 2022

Abstract
Purpose
This study investigated the diagnostic value of simultaneous 18F-fluordeoxyglucose positron emission tomography/magnetic resonance imaging (PET/MRI) in suspected periprosthetic joint infection (PJI) of the hip and knee.

Methods
Sixteen prostheses from 13 patients with suspected PJI were prospectively examined using PET/MRI. Image datasets were evaluated in consensus by a radiologist and a nuclear physician for the overall diagnosis of ‘PJI’ (yes/no) and its anatomical involvement, such as the periprosthetic bone margin, bone marrow, and soft tissue. The imaging results were compared with the reference standard obtained from surgical or biopsy specimens and subjected to statistical analysis.

Results
Using the reference standard, ten out of the 13 prostheses (ten hips, threes knees) were diagnosed with PJI. Using PET/MRI, every patient with PJI was correctly diagnosed (sensitivity, 100%; specificity, 100%). Considering the anatomical regions, the sensitivity and specificity were 57% and 50% in the periprosthetic bone margin, 75% and 33% in the bone marrow, and 100% and 100% in the soft tissue.

Conclusion
PET/MRI can be reliably used for the diagnosis of PJI. However, assessment of the periprosthetic bone remains difficult due to the presence of artefacts. Thus, currently, this modality is unlikely to be recommended in clinical practice.

Modeling the compressive strength of concrete containing waste glass using multi-objective automatic regression
Authors: Golafshani Emadaldin Mohammadi , Kashani Alireza 
Published: May 2022

AbstractSome grades of municipal and industrial waste glass (WG) discarded in landfills can cause environmental issues. One of the efficient solutions to overcome this issue is to use WG in concrete mixtures as aggregate or supplementary cementitious materials. Modeling the compressive strength (CS) of the produced concrete using machine learning methods can provide helpful insights into the effects of WG on concrete properties. In this study, a comprehensive database of concrete containing WG (CCWG) was gathered from 24 peer-reviewed papers. Two different scenarios were considered in the selection of input variables, and a novel machine learning method, called multi-objective multi-biogeography-based programming, was used to predict the CS of CCWG. This algorithm can automatically select the effective input variables, the structure of the equations, and its coefficients. Moreover, the proposed model optimizes the precision and complexity of the developed models simultaneously. The definition of complexity in the optimization problem can help achieve different mathematical equations with various accuracies and assist users in predicting the CS of CCWG even with a limited number of optimal input variables. The results show that the proposed algorithm can introduce several equations with different accuracies, complexities, and input variables to predict the CS of CCWG.
Virtual reality for the assessment and rehabilitation of neglect: where are we now? A 6-year review update
Authors: Cavedoni S. , Cipresso P. , Mancuso V. , Bruni F. , Pedroli E. 
Published: May 2022

AbstractUnilateral spatial neglect (USN) is a frequent repercussion of a cerebrovascular accident, typically a stroke. USN patients fail to orient their attention to the contralesional side to detect auditory, visual, and somatosensory stimuli, as well as to collect and purposely use this information. Traditional methods for USN assessment and rehabilitation include paper-and-pencil procedures, which address cognitive functions as isolated from other aspects of patients’ functioning within a real-life context. This might compromise the ecological validity of these procedures and limit their generalizability; moreover, USN evaluation and treatment currently lacks a gold standard. The field of technology has provided several promising tools that have been integrated within the clinical practice; over the years, a “first wave” has promoted computerized methods, which cannot provide an ecological and realistic environment and tasks. Thus, a “second wave” has fostered the implementation of virtual reality (VR) devices that, with different degrees of immersiveness, induce a sense of presence and allow patients to actively interact within the life-like setting. The present paper provides an updated, comprehensive picture of VR devices in the assessment and rehabilitation of USN, building on the review of Pedroli et al. (2015). The present paper analyzes the methodological and technological aspects of the studies selected, considering the issue of usability and ecological validity of virtual environments and tasks. Despite the technological advancement, the studies in this field lack methodological rigor as well as a proper evaluation of VR usability and should improve the ecological validity of VR-based assessment and rehabilitation of USN.
$$^{17}$$O and $$^{89}$$Y NMR Shift and Relaxation and the Temperature-Independent Pseudogap of the Cuprates
Authors: Avramovska Marija , Nachtigal Jakob , Haase Juergen 
Published: May 2022

AbstractNuclear magnetic resonance (NMR) is a powerful local quantum probe of the electronic structure of materials, but in the absence of reliable theory the interpretation of the NMR data can be challenging. This is true in particular for the cuprate high-temperature superconductors. Over the years, a large base of NMR data became available, which makes a review of early assumptions possible. Very recently, it was shown that all planar $$^{17}$$

17

O NMR shift and relaxation data available in the literature point to a temperature-independent but doping-dependent pseudogap, very similar to what was proposed from the electronic entropy. Here we analyze shift and relaxation of planar O to see whether it follows the very anisotropic and temperature-dependent Cu shift scenario. We find that the O data show a simple, temperature-independent anisotropy in agreement with hyperfine coefficients and orbital shifts predicted by first principles. Furthermore, we show that the original $$^{89}$$

89

Y shift and relaxation data are in agreement with the proposed temperature-independent pseudogap. This pseudogap depends on doping, but also on the family of materials, and the density of states outside or in the absence of the gap is universal for the cuprates; this suggests that the entropy should be similar for all cuprates, as well. Further consequences will be discussed.
