Institutional logic meets global imagining: Kazakhstan’s engagement with China’s Belt and Road Initiative
Authors: Lee Jack T. , Lo William Yat Wai , Abdrasheva Dana 
Published: November 2020

AbstractTheoretical ideas about globalization and internationalization of higher education emphasize the tension among different ideologies of higher education. According to literature, a competition among states, economy, knowledge, and status generates this tension to drive higher education development. This theoretical understanding not only shapes our global imaginations but also permeates the organizational behavior of universities. In this paper, we focus on the institutional logics that motivate universities in Kazakhstan to engage with China’s ambitious Belt and Road Initiative (BRI). We investigate the ways that Kazakhstani higher education interprets and responds to China’s vision of a global order. Based on interviews conducted at 10 higher education institutions (HEIs) in Kazakhstan, we argue that Kazakhstan’s engagement with the BRI circumvents the cultural connectivity and global cooperation that are embraced by Chinese policy discourse and perpetuated by academic literature. Rather, institutional leaders in Kazakhstan operate with a utilitarian logic that seeks revenue generation, links with industry, and opportunities for students in employment and further education. The pursuit of these strategic outcomes demonstrates a bilateral engagement with China rather than the multilateral cooperation envisioned by policymakers. In a higher education system dominated by the state, the institutions in our study exhibit partial agency to accrue pragmatic benefits rather than concede to isomorphic pressures or mimic internationalization from neoliberal contexts. The discrepancy between policy discourse from China and policy reception in Kazakhstan raises questions about the rhetoric of a multipolar global order and the realities of international cooperation in higher education.
Sample Path Properties of Generalized Random Sheets with Operator Scaling
Authors: Sönmez Ercan 
Published: November 2020

AbstractWe consider operator scaling $$\alpha $$
α
-stable random sheets, which were introduced in Hoffmann (Operator scaling stable random sheets with application to binary mixtures. Dissertation Universität Siegen, 2011). The idea behind such fields is to combine the properties of operator scaling $$\alpha $$
α
-stable random fields introduced in Biermé et al. (Stoch Proc Appl 117(3):312–332, 2007) and fractional Brownian sheets introduced in Kamont (Probab Math Stat 16:85–98, 1996). We establish a general uniform modulus of continuity of such fields in terms of the polar coordinates introduced in Biermé et al. (2007). Based on this, we determine the box-counting dimension and the Hausdorff dimension of the graph of a trajectory over a non-degenerate cube $$I \subset {\mathbb {R}}^d$$

Random Perturbations of Matrix Polynomials
Authors: Pagacz Patryk , Wojtylak Michał 
Published: November 2020

AbstractA sum of a large-dimensional random matrix polynomial and a fixed low-rank matrix polynomial is considered. The main assumption is that the resolvent of the random polynomial converges to some deterministic limit. A formula for the limit of the resolvent of the sum is derived, and the eigenvalues are localised. Four instances are considered: a low-rank matrix perturbed by the Wigner matrix, a product HX of a fixed diagonal matrix H and the Wigner matrix X and two special matrix polynomials of higher degree. The results are illustrated with various examples and numerical simulations.
Sets, lies, and analogy: a new methodological take
Authors: Terzian Giulia 
Published: November 2020

AbstractThe starting point of this paper is a claim defended most famously by Graham Priest: that given certain observed similarities between the set-theoretic and the semantic paradoxes, we should be looking for a ‘uniform solution’ to the members of both families. Despite its indisputable surface attractiveness, I argue that this claim hinges on a problematic reasoning move. This is seen most clearly, I suggest, when the claim and its underlying assumptions are examined by the lights of a novel, quite general and, I contend, promising take on inter-theoretic analogy. The ensuing discussion is intended to serve as both a possible case study and a first step towards the broader aim of the paper: namely, to initiate a wider conversation on the methodology of paradox-solving on the one hand, and the use of inter-theoretic analogies on the other.
Modeling Local BES Indicators by Copula-Based Bayesian Networks
Authors: D’Urso Pierpaolo , Vitale Vincenzina 
Published: November 2020

AbstractIn Italy, the measure of the Equitable and Sustainable Well-being is provided by the Italian Institute of Statistics by means of a dashboard of basic and composite indicators. To investigate the dependence structure between the different domains of well-being, we propose the use of Non-Parametric Bayesian Networks based on the normal copula distribution, that allow to explore the conditional independence relationships between the composite indicators. The main advantage of the non-parametric models is that, as opposed to the parametric approach, they do not require any assumption on the marginal distributions of the variables. The proposed model is applied to the Equitable and Sustainable Well-being indicators measured at the provincial level and enriches the analysis of well-being by inspecting similarities and differences between Italian urban areas and territories.
Beyond kappa: an informational index for diagnostic agreement in dichotomous and multivalue ordered-categorical ratings
Authors: Casagrande Alberto , Fabris Francesco , Girometti Rossano 
Published: November 2020

AbstractAgreement measures are useful tools to both compare different evaluations of the same diagnostic outcomes and validate new rating systems or devices. Cohen’s kappa (κ) certainly is the most popular agreement method between two raters, and proved its effectiveness in the last sixty years. In spite of that, this method suffers from some alleged issues, which have been highlighted since the 1970s; moreover, its value is strongly dependent on the prevalence of the disease in the considered sample. This work introduces a new agreement index, the informational agreement (IA), which seems to avoid some of Cohen’s kappa’s flaws, and separates the contribution of the prevalence from the nucleus of agreement. These goals are achieved by modelling the agreement—in both dichotomous and multivalue ordered-categorical cases—as the information shared between two raters through the virtual diagnostic channel connecting them: the more information exchanged between the raters, the higher their agreement. In order to test its fair behaviour and the effectiveness of the method, IA has been tested on some cases known to be problematic for κ, in the machine learning context and in a clinical scenario to compare ultrasound (US) and automated breast volume scanner (ABVS) in the setting of breast cancer imaging.
Construction of embedded fMRI resting-state functional connectivity networks using manifold learning
Authors: Gallos Ioannis K. , Galaris Evangelos , Siettos Constantinos I. 
Published: November 2020

AbstractWe construct embedded functional connectivity networks (FCN) from benchmark resting-state functional magnetic resonance imaging (rsfMRI) data acquired from patients with schizophrenia and healthy controls based on linear and nonlinear manifold learning algorithms, namely, Multidimensional Scaling, Isometric Feature Mapping, Diffusion Maps, Locally Linear Embedding and kernel PCA. Furthermore, based on key global graph-theoretic properties of the embedded FCN, we compare their classification potential using machine learning. We also assess the performance of two metrics that are widely used for the construction of FCN from fMRI, namely the Euclidean distance and the cross correlation metric. We show that diffusion maps with the cross correlation metric outperform the other combinations.
Agil, hierarchiefrei und selbstorganisiert im New Work oder überwältigt von Systemstrukturen und unterdrückten gruppendynamischen Prozessen im New Office
Authors: Schneider Tomas 
Published: November 2020

ZusammenfassungDieser Beitrag in der Zeitschrift Gruppe. Interaktion. Organisation. (GIO) stellt eine explorative qualitative Studie zum Erleben von Sinn und Bindung durch Mitarbeitende in agilen New Work Umwelten vor, indem sie Wirkungen von Selbstorganisation, flachen Hierarchien, und elaborierten agilen Systemarchitekturen im Gegenlicht von persönlichen Beziehungen, gruppendynamischen Prozessen und Aspekten des psychologischen Empowerments betrachtet.Globalisierung, Digitalisierung und demographischer Wandel lassen Wettbewerb und Produktivität, sowie Qualifikationsanforderungen immer rasanter wachsen. Währenddessen werden qualifizierte Mitarbeitende jüngerer Generationen (X, Y, Z) rarer und fordern jenseits ökonomischer Auskömmlichkeit entsprechende Ausgestaltungen ihrer Arbeitsverhältnisse. Das Erleben von Selbstwirksamkeit und Sinn, sowie persönliche Entwicklung und hohe individuelle Freiheitsgrade werden bedeutsam und der Ruf nach neuen Arbeitsstrukturen laut.Unter „New Work“ versammeln sich so Organisationsansätze, welche die Arbeitszufriedenheit, das Empowerment und die intrinsische Motivation, sowie die Verbundenheit mit Projekten oder Organisationen stärken sollen. Agile Arbeitsmethoden mit selbstorganisierenden Scrum-Teams treffen häufig auf Neudefinitionsversuche von Arbeit aus der Start-Up-Welt während sich Bestandsunternehmen um Adaption bemühen.Der Artikel hinterfragt, inwieweit qualitative Änderungen von Arbeit gelingen oder eher neu gestaltete Arbeitsumgebungen entstehen.In einer explorativen qualitativen Studie wurde hierfür in zwei New Work IT-Unternehmen mit halboffenen Interviews untersucht, welche Zielsetzungen die Leitungsebenen formulieren, an welchen Modellen sie sich orientieren, welche Rolle das Empowerment spielt, was konkret umgesetzt wird. Dem wurden die Erwartungen und die Rezeption durch die Mitarbeitenden sowie gruppendynamische Perspektiven gegenübergestellt.Im Sample wird u.a. deutlich, dass eine Delegation von Hierarchie an Systemarchitekturen oder in Selbstorganisationzirkel wenig geeignet ist, Hierarchie zu beseitigen. Genauso zeigt sich, dass Selbstorganisation an sich nicht unbedingt Probleme löst oder Komplexität reduziert. Gleichzeitig findet eine Bindung der Mitarbeitenden vor allem an den Rändern der eingesetzten New Work Methoden und weitgehend unabhängig von diesen statt. Schließlich bildet sich ab, dass die vorgefundene Vernachlässigung der Beziehungsebene und damit team- und gruppenspezifischer Dynamiken nicht durch Systemstrukturen aufgefangen werden können, sondern vielmehr deutlicher Beachtung bedürfen.
Toward a Strong-Sense Validation Benchmark Database for Numerical Ladle Flow Models
Authors: Haas Tim , Suarez Ana Lia , Eickhoff Moritz , Pfeifer Herbert 
Published: November 2020

Abstract
In numerical computation of ladle metallurgy, multiphase models are essential. Still, these models are afflicted with great uncertainty, making a validation with experimental data mandatory. Validation experiments fundamentally differ from physical modeling experiments because emphasis is on a complete documentation of all boundary conditions and a detailed uncertainty assessment. For this work, the experimental design for a comprehensive accuracy assessment of numerical models and reported quantities were jointly determined with international numerical experts. The framework comprises a plume analysis and flow measurements in the single- and multiphase regions of a water model with defined conditions. All influencing factors are documented extensively and their contribution to the overall data uncertainty is quantified. Detailed data are made publicly available within a validation benchmark database for isothermal multiphase flow in metallurgical ladles. A first draft of a standardized validation procedure, including a single number validation score, is proposed. Using the available data, the accuracy of numerical models can be quantified more accurately and comparably, which helps in advancing the model’s further development. It also lays the foundation for a standardization of the validation process, which can lead to greater acceptance of the numerical results.

Published: November 2020

AbstractInterstitial lung disease (ILD) represents one of the most severe extra-muscular features of idiopathic inflammatory myositis (IIM). We aimed to identify any clinical and serological predictors of ILD in a monocentric cohort of 165 IIM patients.ILD+ patients were defined as having restrictive impairment in lung function tests and signs of ILD at chest high-resolution computed tomography (HRCT). Available HRCT images were centralized and classified in different ILD patterns: non-specific interstitial pneumonia (NSIP), organizing pneumonia (OP), usual interstitial pneumonia-like (UIP), indeterminate for UIP, and interstitial lung abnormalities (ILA). Lung function test data were recorded at onset, at 1 and 5 years after ILD diagnosis.ILD was found in 52 IIM patients (31.5%): 46.2% was affected by anti-synthetase syndrome (ARS), 21% by polymyositis (PM), 19% by dermatomyositis (DM), and 13.5% by overlap myositis. Most of ILD+ showed NSIP (31.9%), OP (19%), indeterminate for UIP (19%), and UIP (12.8%) patterns. At multivariate analysis, ILD was predicted by anti-Ro52 (p: 0.0026) and dyspnea (p: 0.015) at IIM onset. Most of ILD onset within is 12 months after IIM. In five cases, ILD occurs after 12 months since IIM diagnosis: these patients more frequently show dry cough and anti-Ku antibodies. Anti-Ro52 + ILD patients showed a significant increase of DLCO at 1 and 5 years of follow-up, compared with anti-Ro52 negative cases.ILD occurs in about one third of IIM and was predicted by dyspnea at onset and anti-Ro52 antibodies. Anti-Ro52 defines a subgroup of ILD showing a significant improvement of DLCO during follow-up. This retrospective study has been approved by local ethic committee (ASST-Spedali Civili of Brescia, Italy); protocol number: NP3511
IMPROV-ED trial: eHealth programme for faster recovery and reduced healthcare utilisation after CABG
Authors: van Steenbergen G. J. , van Veghel D. , ter Woorst J. , van Lieshout D. , Dekker L. 
Published: November 2020

Abstract
Background
After coronary artery bypass grafting (CABG), healthcare utilisation is high and is partly unplanned. eHealth applications have been proposed to reduce healthcare consumption and to enable patients to get actively involved in their recovery. This way, healthcare expenses can be reduced and the quality of care can be improved.

Objectives
We aim to evaluate whether the use of an eHealth programme can reduce unplanned healthcare utilisation and improve mental and physical health in the first 6 weeks after discharge in patients who underwent CABG. In addition, patient satisfaction and use of the eHealth programme will be evaluated.

Methods
For this single-centre randomised controlled trial, at least 280 patients referred for CABG will be included at the preoperative outpatient clinic and randomised to an intervention or control group. The intervention group will have access to an eHealth programme, which consists of online educational videos developed by the Dutch Heart Foundation and postoperative video consultations with a physician. The control group will receive standard care and will not have access to the eHealth programme. The primary endpoint is healthcare utilisation; other endpoints include anxiety, duration of recovery, quality of life and patient satisfaction. Participants will complete several questionnaires at 6 time points during the study.

Results
Patient enrolment started in February 2020 and completion of the follow-up period is expected in August 2021.

Conclusion
This randomised trial was initiated to test the hypothesis that patients who are partaking in our eHealth programme use less unplanned care and experience a better quality of life, less anxiety and a faster recovery than controls.
Coexistence of a rare type of ectopic kidney with atypical renal vasculature

Published: November 2020

AbstractKnowledge of anatomical anomalies is significant for all specialists in clinical practice and may prevent serious complications following medical procedures. This report presents the rare crossed fused renal ectopia (CFRE) with atypical renal vasculature in cadaver of a 68-year-old man. The ectopic kidney was located on right side with four renal veins, three renal arteries, two ureters, where one of them is double. The embryological background, as well as the potential clinical significance of this morphological variation, is discussed. An interventional radiological and surgical procedure should be appropriately implemented to treat anomalies of vessels and CFRE.

Published: November 2020

ZusammenfassungWearable Devices versprechen durch ihre motivierende Wirkung einen wichtigen Beitrag zur Bindung des Individuums an körperlich-sportliche Aktivitäten und somit zum Aufbau und Erhalt von Gesundheit und Leistungsfähigkeit in Zeiten des digitalen gesellschaftlichen Wandels. Übergeordnetes Ziel der vorliegenden Untersuchung war die Beurteilung der Testgüte von Wearable Devices anhand eines marktrelevanten Gerätes, der Garmin fēnix® 5. Als Forschungsdesiderat wurde der Reliabilitätsaspekt der Methodenkonkordanz identifiziert. Zur Überprüfung der Methodenkonkordanz wurden das Stresslevel bei kognitiver Stressinduktion, der Kalorienverbrauch bei moderater Ausdauerlaufbelastung sowie die maximale Sauerstoffaufnahme bei Laufausbelastung von 30 männlichen Probanden (Alter: 23,13 ± 2,5 Jahre; BMI: 24,95 ± 2,45 kg/m2) mit der Garmin fēnix® 5 bestimmt und die Ergebnisse mit denen im Feld gängigen Referenzmethoden Elektrokardiographie, Indirekte Kalorimetrie bzw. Spiroergometrie verglichen. Zur rechnerischen Überprüfung der Methodenkonkordanz diente Lin’s Konkordanzkorrelationskoeffizient (CCCLin). Die Ergebnisse zeigen eine hohe Präzision der Garmin fēnix® 5 im Vergleich mit der Referenzmethode Elektrokardiographie hinsichtlich der Messung des notwendigerweise z-standardisierten Stressparameters (p = 0,89) sowie eine gerade mittlere exakte intrainidividuelle Konkordanz mit der Referenzmethode Indirekte Kalorimetrie bzw. Spiroergometrie hinsichtlich der Messung des Parameters Kalorienverbrauch (CCCLin = 0,43 [p = 0,52, Cb = 0,82]) bzw. maximale Sauerstoffaufnahme (CCCLin = 0,50 [p = 0,77, Cb = 0,66]). Die Garmin fēnix® 5 kann somit zumindest bei erstmaliger Verwendung nicht als hinreichend konkordante Alternative zu den gängigen aktivitäts- und leistungsbezogenen Referenzmethoden empfohlen werden.
Nanometric polishing of lutetium oxide by plasma-assisted etching
Authors: Lyu Peng , Lai Min , Fang Feng-Zhou 
Published: November 2020

AbstractPlasma-assisted etching, in which the irradiation of hydrogen plasma and inorganic acid etching are integrated, is proposed as a novel polishing method for sesquioxide crystals. By means of this approach, low damage and even damage-free surfaces with a high material removal rate can be achieved in lutetium oxide surface finishing. Analysis of transmission electron microscopy and X-ray photoelectron spectroscopy reveal that plasma hydrogenation converts the sesquioxide into hydroxide, which leads a high efficient way to polish the surfaces. The influences of process conditions on the etching boundary and surface roughness are also qualitatively investigated using scanning electron microscope and white light interferometry. The newly developed process is verified by a systematic experiment.
Vom situationalen Interesse zum Lernerfolg: Lesegeschichten im Chemieunterricht der Sekundarstufe I
Authors: Reschke Tim , Koenen Jenna , Sumfleth Elke 
Published: November 2020

ZusammenfassungSchülerinnen und Schüler zeigen im Fach Chemie häufig Defizite im Fachwissen und gleichzeitig ein geringes Fachinteresse. Eine vermehrte Anregung des situationalen Interesses könnte einen ersten Schritt in Richtung einer positiven Entwicklung des Fachinteresses sein. Eine Möglichkeit hierzu bieten Lernmaterialien in Form von chemiebezogenen Lesegeschichten. Allerdings mangelt es an empirischen Studien zur Wirkung solcher Texte auf das situationale Interesse und den Lernerfolg. Darüber hinaus fehlt ein Vergleich mit anderen Textarten wie dem Sachtext, der meist vorkommenden Textart in Chemieschulbüchern. Im Rahmen der vorliegenden Studie wurden daher verschiedene Lesegeschichten entwickelt und untersucht, inwieweit sich diese bei fachlich gleichen Inhalten in ihrer Wirkung von Sachtexten unterscheiden, und zwar im Hinblick auf das situationale Interesse und den Lernerfolg von Schülerinnen und Schülern. Die Ergebnisse zeigen, dass der Lernerfolg mit Lesegeschichten höher ist als der mit Sachtexten. Beim situationalen Interesse zeigen sich Geschlechtereffekte zugunsten der Mädchen, die stärker an der Lesegeschichte interessiert sind und dadurch länger mit dieser lernen als die Jungen. Insgesamt lässt sich für die Mädchen ein Modell hinsichtlich des Zusammenhangs zwischen der jeweiligen Textart (mit Vorteilen für die Lesegeschichte), dem situationalen Interesse, der Lernzeit und dem Lernerfolg abbilden.
Torn between responsibility and loyalty: how the veterinarian profession designs antibiotic resistance policies that shake its foundations
Authors: Surdez Muriel , Piquerez Lorène , Hobeika Alexandre 
Published: November 2020

AbstractAntimicrobial resistance (AMR) policies, which aim to redefine how antibiotics are used, reshape the veterinary profession’s relationships in at least two ways. The policies can give state veterinarians greater power over practising veterinarians and thus change the relationship between the profession and the government supposed to regulate it. The policies also call for coordination with other relevant professionals, mainly in the areas of human medicine and food safety, which can limit the veterinary profession’s autonomous decision-making. Based on a survey of veterinarians working at different levels of the administration and their non-veterinary colleagues in Switzerland, it is shown that AMR policies, by strengthening the administration’s planning and supervisory functions, do contribute to increased state control of the veterinary profession. However, this shift is limited because implementing the policies requires negotiating with representatives of the profession.
