Heterostructured Redox‐Active V2O5/SnO2 Oxide Nanocatalyst for Aqueous‐Phase Oxidation of Furfural to Renewable Maleic Acid
Authors: Malibo Petrus M. , Makgwane Peter R. , Baker Priscilla G. 
Published: June 2020

AbstractIn this paper, we report on the synthesis of heterostructured V2O5/SnO2 nanocatalysts with varying vanadium metal loadings of 5–30 wt %. The catalytic performance of the designed catalysts was evaluated in the oxidation reaction of furfural to maleic acid using hydrogen peroxide. The synthesis method afforded highly dispersed nanosized VOx species with predominant exposed V5+ and V4+ on SnO2 oxide. Such structural interface developments of the heterostructured V2O5/SnO2 catalyst resulted into modified electronic structure; phase compositions and textural properties of the individual V and Sn metal oxides with respect to varying V‐metal loadings, which lead to improved catalytic performances. Under optimized reaction conditions, a 60 % yield of maleic acid was achieved in furfural oxidation reaction. Based on characterization results, the high surface area and low V‐metal loading (∼9.3 wt % vanadium) presented the most redox active V2O5/SnO2 catalyst. At low V‐metal loadings the catalyst is populated with the presence of VOx monomeric and polymeric species which are proposed to induce the highly active vanadium sites. This was confirmed for the most active catalyst to possess vanadium with the predominant V4+ state and superoxide oxygen. The catalytic performance showed by V2O5/SnO2 present a solid catalyst derived from earth‐abundant and cheap metals for the catalytic oxidation upgrade of biomass typical furfural to important value‐added maleic acid intermediate chemical.
Platform governance matters: How platform gatekeeping affects knowledge sharing among complementors
Authors: Zhang Yuchen , Li Jingjing , Tong Tony W. 
Published: June 2020

AbstractResearch SummaryOrchestrating complementors' value creation activities is critical to platform owners but is challenging. Emerging literature on platform governance suggests that platform access control can shape complementors' contributions to platforms. We extend this literature by using the coopetition framework from strategic management to examine the relationship between platform gatekeeping, a prominent policy for governing platform access, and knowledge sharing among complementors. Exploiting the iOS 7 jailbreak as an exogenous shock to Apple's gatekeeping policy and tracing iOS and Android app developers' knowledge sharing activity on an online forum, we find causal evidence that a lapse in gatekeeping reduces knowledge sharing among iOS app developers. Further, this effect is mitigated among developers with greater knowledge complexity but magnified among those with greater knowledge routineness.Managerial SummaryPlatform owners can use governance policies, such as gatekeeping, to control complementors' platform access and shape their value creation activities. This study examines how platform access control affects the interactions among complementors in the form of knowledge sharing. We find that iOS app developers share knowledge less frequently after a lapse in Apple's gatekeeping policy, suggesting that strict platform access control can facilitate complementors' interactions with one another. Further, the decrease in knowledge sharing is more pronounced among app developers with routine knowledge and less so among those with complex knowledge, indicating that complementors' characteristics also matter. This study highlights the value of understanding the impact of the design and deployment of platform governance policies on complementors' interactions and value creation activities more generally.

AbstractIn the present study, reactive powder concrete (RPC) was investigated with three different types of single fibers that is, steel fiber (SF), glass fiber (GF), and carbon fiber (CF). Moreover, the effect of hybrid SF‐GF, GF‐CF, and CF‐SF on RPC was also investigated. In case of both single and hybrid fiber‐reinforced RPCs, a constant volume fraction of 2% fiber was used. A plain RPC was also produced that served as a reference/control mix. Studied parameters include compressive strength, modulus of elasticity, peak strains in compression, compression toughness, total energy absorbed in compression, splitting tensile strength, and flexural strength. Results showed that among single fiber‐reinforced RPCs, CF‐RPC performed better than both SF‐ and GF‐RPC in compression. Whereas, single SF‐RPC performed better than GF‐ and CF‐RPC in splitting tensile and flexural strength, single SF‐RPC showed significant softening response compared with single CF and GF‐RPC. CF‐RPC showed comparable performance to that of the SF‐RPC in both tensile and flexural strength. But CF‐RPC showed lower toughness than SF‐RPC. Hybridization of 1%SF and 1%CF yielded maximum overall mechanical performance among both single and hybrid fiber RPCs. Maximum attribution (17–38%) of fibers was toward flexural strength compared to other strength properties.
Improving Gravity Estimation Accuracy for the GT-2A Airborne Gravimeter Using Spline-Based Gravity Models
Authors: Vyazmin Vadim S. , Bolotin Yuri V. , Smirnov Anton O. 
Published: June 2020

AbstractIn this article, we propose a technique for processing airborne gravimetry measurements at repeat drape lines. To model gravity along a line, we use cubic B-splines. The unknown parameters of the model (the spline coefficients) are to be estimated from the measurements. In order to take into account dependance of gravity on position, the same set of the spline coefficients is assumed for gravity modeling at each repeat line. Gravity estimation is performed with the Kalman filter. The spline coefficients are included in the state vector of the filter as unknown constants. The developed estimation algorithm was tested using measurements of the GT-2A gravimeter collected at repeat drape lines. The gravity estimates obtained with the use of B-splines are more accurate compared with those obtained with the standard technique, in which gravity is modeled as a stochastic process in the time domain.
The Practice of Whole Person-Centred Healthcare
Authors: Broom Brian 
Published: June 2020

AbstractIn this text, clinical immunologist and psychotherapist Brian Broom draws attention to the fact that as patients we are all persons, and more than that. We are persons-in-relationship. Any therapy that reduces us to a more limited view of persons, such as objects to be technologically manipulated, is going to have serious limitations, if not in many cases be profoundly inadequate. Broom provides an account of the emergence in New Zealand of a non-dualistic, whole person-centred form of clinical practice, particularly in relation to the treament of physical disease of all kinds. He translates into clinical reality the dispositionalist call for a more holistic understanding of the causes of health and illness, as presented in Part I. The original move towards whole person-centredness in New Zealand was stimulated by the phenomenological recognition of physical diseases emerging in close association with the person’s significant life events and meanings. Most challenging, and yet most stimulating, was the appearance of symbolic disorders, which drove the theoretical struggle towards a unitive view of persons. The resulting non-dual assumptions concerning the personhood of patients and their illnesses mean that clinicians have a multidimensional, multifactorial and multicausal attitude to their work with people. It turns out that from a clinician’s perspective the work is impossible unless there is, firstly, a clear habitual non-dual framework and, secondly, the clinician acquires listening skills based in deeply relational principles. This combination is profoundly meaningful and helpful to many patients and appears to drive the healing processes.
Above and Beyond Statistical Evidence. Why Stories Matter for Clinical Decisions and Shared Decision Making
Authors: Low Matthew 
Published: June 2020

AbstractPhysiotherapist Matthew Low is specialised in treating patients with musculoskeletal disabilities and uses dispositionalism as a framework in his clinical work. Low has developed and put into practice a clinical approach, following the dispositionalist theory, based on a ‘clinical alliance’ between patient and healthcare professional, who together try to make sense of the patient’s situation. This happens through the co-construction of a narrative, where the causal complexity of the patient’s experience is modelled using the dispositionalist vector model. In this chapter, Low translates into clinical reality several of the philosophical issues presented in Part I. First, he shows the necessity of considering the totality of causal evidence, including the qualitative and intrinsic propensities of the single patient at hand. Second, he demonstrates how patient narratives should be considered causal evidence and shows that evidence from population trials is just one piece of the puzzle for understanding causality in the single case. Low further reflects on the importance of moving past the biomedical and the bio-psychosocial models, that fail to honour the stories the patient tells or the full experience of persistent pain and how it affects (and is affected by) every aspect of one’s life. Taking the patients’ narrative seriously and working together with them on a long-term plan are essential tools when it comes to treating persistent pain.
Latin American Transnational Political Engagement: Steering Civic Movements and Cultural Repertoires from the Global City of Brussels
Authors: Lara-Guerrero Larisa , Vivas-Romero María 
Published: June 2020

AbstractMigrants are active civic agents participating in transnational social movements. They create, transform, and exploit transnational networks to engage in political movements in both their homeland and the hostland. In this chapter, we demonstrate that migrants accumulate political and cultural knowledge, symbols, emotions of hope, nostalgia, and political practices as a result of their emigration experience. Using empirical examples of Latin American migrants living in Brussels, we argue that social remittances shape the way migrants: (1) develop their political and cultural repertoires of contention; (2) constitute their social identities and networks influencing their political behavior; and (3) embody the ideologies, ideas, and norms of their homeland, while being influenced by the multiple cities in which they have lived. We conclude that Latin American migrants have managed to develop and sustain transnational fields of social and political mobilization to defend their politi-cal struggles and ideals from Brussels itself.
The Trans-European Mobilization of “Generation Identity”
Authors: Nissen Anita 
Published: June 2020

AbstractThis contribution explores the transnational mobilization of the European new right youth movement Generation Identity (GI). Employing frame analysis on GI’s transnational protest events in the period 2015–2017, the chapter explores how the GI activists produce bases for collective action through the construction and assignment of protagonist and antagonist identities. GI premises the term “identity” on an ethno-pluralist understanding of society, which implies a wish for an ethnic segregation of the world’s population, and a nostalgic yearning for a time of European ethnic homogeneity. The movement thus hopes for a “future return” of a European continent free from non-European, especially Muslim, “others”, which should be achieved by battling today’s Universalist, multicultural, and egalitarian principles, together with mass-immigration and so-called “Islamization”. An analysis of the movement’s collective action frames during the European refugee crisis reveals that the GI groups create a protagonist identity around the notion of a “fighting community,” forming a symbolic European bulwark against their antagonists, i.e. the “invading” Muslim immigrants, and the European actors, who permit their residence on the continent. On the other hand, the antagonist identity construction revolves around portraying the pro-migrant actors and Western European governments as the villains, who act against the interests of the autochthonous European population. At the same time, by pointing to the negative consequences of particularly Muslim third country immigration, and questioning the migrants and refugees’ residence claims, GI is pursuing the overall ambition of returning Europe to its imaginary ethnically homogeneous roots.
Globalisation, Education and Policy Reforms
Authors: Zajda Joseph 
Published: June 2020

AbstractThe topic of globalisation and education reform has assumed immense importance in the discourse and policies of many bodies and agencies across the international arena. An increasing number of countries and governments have concluded that globalisation, education and policy research approach to learning and teaching should be instituted and deployed as one of the main lines of attack on some of the major problems needing to be addressed in the future. The policy documents and statements of the UNESCO, OECD, the European Parliament, the Nordic Council of Ministers and the Asia-Pacific Economic Co-operation Forum (APEC) reveal a commitment to globalisation and education reforms. There are other regional alliances that are grappling differently with issues of anti-globalisation trends of Brexit, in the Global South and in developing and underdeveloped nations also.
The National Concept of Education Quality
Authors: Yuan Zhenguo 
Published: June 2020

AbstractEducation quality has long been debated by education philosophers as what education is good (Burbules 2004). In the global practices, many countries have engaged in exploring how to make learners acquire good education. In the Education Policy Outlook 2015 published by OECD (2015), about 16% of education reform measures by the OECD member countries focused on education quality and equity.
Changes in Educational Institutions in China: 1978–2020
Authors: Fan Guorui 
Published: June 2020

AbstractThis chapter reviews key historical documents and reform events and outlines China’s educational reform and development in the macro context of 40 years of social, political, and economic changes. Professor Elizabeth J. Perry (2014) noted the significance of studying contemporary China from the Reform and Opening-up in the field comparative politics and public policy, which marked the beginning of “a new era of developing socialism with Chinese characteristics” (Xi 2017). This chapter focuses on the process of education institutional changes and innovation and identifies the educational reform and opening-up as a predominant narrative, aiming at breaking through the obstacles of existing institutional structures and promoting sustainable development of education. A key challenge to reforming education institution lies in how to solve the Chinese governance dilemma of loosening control in chaos or tightening control in suffocation (“Yifang Jiuluan, Yishou Jiusi” “一放就乱 一收就死”). Solutions are suggested as exploring appropriate tensions among education institutional factors and stimulating the vitality of educational elements and institutions under appropriate tensions.

Published: June 2020

ZusammenfassungDiabetes mellitus Typ 1 ist die häufigste endokrinologische Erkrankung bei Kindern und Jugendlichen unter 15 Jahren. Eine Heilungsperspektive bezüglich der Autoimmunreaktion gegen die insulinbildenden Betazellen ist weiterhin nicht in Sicht. Dennoch konnte durch technische Innovationsschübe bei Glukosesensoren, Insulinpumpen und Steuerungsalgorithmen innerhalb der letzten Jahre die Stoffwechselkontrolle optimiert werden. Diese Entwicklungen führen zusammen mit individuellen Diabetesschulungen und psychosozialer Unterstützung zu einer deutlichen Verbesserung der Versorgung.In diesem Übersichtsartikel wird die aktuelle Versorgungssituation von Kindern und Jugendlichen mit Typ-1-Diabetes sowie ihren Eltern dargestellt. In Deutschland ist die multidisziplinäre, spezialisierte Versorgung durch Teams aus Kinder- und Jugenddiabetolog*innen, Diabetesberater*innen, Sozialarbeiter*innen und Kinder- und Jugendpsychotherapeut*innen seit vielen Jahren etabliert und führt zu einer im internationalen Vergleich sehr guten Versorgungsqualität. Fokussiert werden die Diabetesschulung mit dem Schwerpunkt, das Selbstmanagement optimal zu unterstützen, die psychosoziale Begleitung und Intervention sowie die Inklusion in Schulen und Kindertagesstätten. Wir gehen außerdem auf neue soziale Entwicklungen der Diabetes-Online-Community ein. Ein aktuelles Beispiel ist die patientenbetriebene Bewegung „Do-It-Yourself Artificial Pancreas System“ (DIY-APS), die als Open-Source-Projekt mittlerweile Innovationsgeber auch für Medizinproduktehersteller ist. Zum Schluss beleuchten wir die damit verbundenen Chancen, aber auch die Verschiebung der klassischen Arzt-Patienten-Rollen.

Authors: Szczotkowski D. , Neik C. , Polak U. , Wittwer M. , Kohlmann T. 
Published: June 2020

Zusammenfassung
Hintergrund
Durch eine bundesweite Beurteilung von Durchgangsarzt(D)-Berichten sollte die Dokumentationsqualität im Durchgangsarztverfahren der Deutschen Gesetzlichen Unfallversicherung (DGUV) systematisch erfasst werden. Peer-Review-Verfahren sind bewährte Instrumente zur Sicherung der Prozessqualität.

Material und Methoden
Für eingeschlossene D‑Ärzte wurden zufällig 30 D-Berichte mit besonderer Heilbehandlung aus dem Jahr 2017 ausgewählt, anonymisiert und webbasiert von einem zufällig zugeteilten Beurteiler (Peer) mit einer Checkliste bewertet. Diese umfasste 9 Beurteilungskategorien mit dichotomem Antwortformat (Mangel/kein Mangel). Zur Gesamteinschätzung wurde für jeden D‑Bericht eine Gesamtnote („sehr gut“ bis „ungenügend“) vergeben.

Ergebnisse
Insgesamt bewerteten 82 Peers 30.384 D‑Berichte. Jeder dritte D‑Bericht wies keine Mängel auf. Die häufigsten Mängel waren in der Beurteilungskategorie „Angaben zum Unfall“ zu beobachten. Die durchschnittliche Gesamtnote betrug 2,6, wobei es auf der Ebene der evaluierten D‑Ärzte deutliche Qualitätsunterschiede gab (beste: 1,5; schlechteste: 4,1). Alle evaluierten D‑Ärzte erhielten individuelle Qualitätsberichte, in denen die Kernergebnisse beschrieben wurden.

Schlussfolgerung
Das erste bundesweite Peer-Review der DGUV konnte sich als praktikables und valides Qualitätssicherungsverfahren für D‑Berichte bewähren. Die Qualität der Berichte kann allgemein als gut eingeschätzt werden. Die DGUV plant, das Verfahren unter Berücksichtigung weiterer D‑Arzt-Gruppen zu wiederholen.
Development of certified reference materials for the determination of cadmium and acrylamide in cocoa

Published: June 2020

AbstractSince 1 January 2019 a maximum content of 0.6 mg kg−1 cadmium (Cd) in cocoa powder sold to the final consumer or as an ingredient in sweetened cocoa powder sold to the final consumer (drinking chocolate) is set by the Commission Regulation (EU) No. 488/2014. Monitoring compliance with the specified limit value requires analytical measuring methods and reference materials for quality control. However, suitable certified reference materials intended for quality assurance and quality control purposes are still lacking. Therefore, three cocoa reference materials (ERM®-BD513, ERM®-514 and ERM®-515) were developed according to the requirements of ISO 17034 and the recommendations of ISO Guide 35. The whole process of reference material development, including material preparation, assessment of homogeneity and stability, characterisation and value assignment is presented. The assignment of the certified mass fractions was based upon an interlaboratory comparison study involving 19 expert laboratories for Cd and 12 laboratories for acrylamide. The certified mass fractions and expanded uncertainties (k = 2) of the reference materials were (0.181 ± 0.009) mg kg−1 Cd (ERM®-BD513), (0.541 ± 0.024) mg kg−1 Cd (ERM®-BD514) and (0.690 ± 0.029) mg kg−1 Cd (ERM®-BD515). Acrylamide contents are given for information.

Abstract
Aim of the study
The present study aimed to identify risk factors for unsuccessful CR.

Introduction
Closed reduction (CR) represents the gold standard for treatment of developmental dysplasia of the hip (DDH), but to a minor percentage, it fails to reduce dysplastic hips successfully.

Methods
Seventy-three dysplastic hips underwent closed reduction and post-interventional MRI of the pelvis. MRIs were evaluated for successful reduction of the hip, volumes of femoral heads, and acetabular diameter. Initial treatment results were correlated to AC angles at two years of follow-up. Contralateral, healthy hips served as control.

Results
Out of 73 instable, dysplastic hips, there were nine cases of CR failure. These cases showed significantly increased femoral head volumes (p = 0.002) and a significantly (p = 0.02) larger ratio of femoral head volume to acetabular opening area. There was no significant difference (p = 0.15) in acetabular diameter between both groups. At two years of follow-up, AC angles were significantly (p = 0.003) larger and pathologic in cases of CR failure.

Conclusion
Exclusive enlargement of the femoral head is a risk factor for unsuccessful reduction and its ratio to the acetabular opening surface is predictive for CR success in DDH.
