Published: April 2021

Zusammenfassung
Hintergrund
Die Schädelbasis stellt eine chirurgisch hochkomplexe Einheit dar und ist häufig nur über kombinierte Zugangswege erreichbar. Neu entwickelte Operationstechniken mit Verwendung von mikrochirurgischen Visualisierungsverfahren und aktiven Instrumenten („powered instruments“) sowie „Multi-Port-Zugänge“ ermöglichen neue, weniger traumatische Operationskorridore. Hierfür ist eine enge interdisziplinäre Zusammenarbeit zwischen dem Chirurgen aus dem Fachgebiet der Hals-Nasen-Ohren-Heilkunde sowie dem Neurochirurgen notwendig. Die aktuell etablierten Zugangsverfahren zur zentralen Schädelbasis werden aufgrund eigener klinischer Erfahrungen und unter Berücksichtigung der Entität systematisiert und in Bezug auf die aktuelle Studienlage erörtert.

Material und Methode
Es erfolgte eine retrospektive, qualitative und deskriptive Auswertung der Operationsberichte einzelner Patienten, die in der Zeit zwischen 2006 und 2019 mit Pathologien an der zentralen Schädelbasis chirurgisch gemeinsam von der Neurochirurgie und der Hals-Nasen-Ohren-Heilkunde/Kopf- und Halschirurgie behandelt wurden.

Ergebnisse
Die chirurgischen Zugangswege zur zentralen Schädelbasis ließen sich nachfolgend kategorisieren, teilweise auch in Kombination derselben, als sog. Multi-Port-Zugänge: transnasal-transsphenoidal, subfrontal, subtemporal, transzygomatisch, transpterygonal, transpetrös, translabyrinthär und subokzipital. Maßgebend für die Wahl des Zugangswegs waren die Lokalisation und Art der Pathologie, sowie der mögliche Anspruch auf Funktionserhalt und Komplettentfernung.

Schlussfolgerung
Aufgrund der Komplexität der Strukturen der zentralen Schädelbasis, der unterschiedlichsten Tumorentitäten und der benötigten Fachkompetenz unterschiedlicher Facharztdisziplinen bleibt die Chirurgie der zentralen Schädelbasis eine Herausforderung, der man sich nur an speziellen, nach den Kriterien der Gesellschaft für Schädelbasischirurgie e. V. zertifizierten Kompetenzzentren stellen sollte.
Critical speed estimated by statistically appropriate fitting procedures

Abstract
Purpose
Intensity domains are recommended when prescribing exercise. The distinction between heavy and severe domains is made by the critical speed (CS), therefore requiring a mathematically accurate estimation of CS. The different model variants (distance versus time, running speed versus time, time versus running speed, and distance versus running speed) are mathematically equivalent. Nevertheless, error minimization along the correct axis is important to estimate CS and the distance that can be run above CS (d′). We hypothesized that comparing statistically appropriate fitting procedures, which minimize the error along the axis corresponding to the properly identified dependent variable, should provide similar estimations of CS and d′ but that different estimations should be obtained when comparing statistically appropriate and inappropriate fitting procedure.

Methods
Sixteen male runners performed a maximal incremental aerobic test and four exhaustive runs at 90, 100, 110, and 120% of their peak speed on a treadmill. Several fitting procedures (a combination of a two-parameter model variant and regression analysis: weighted least square) were used to estimate CS and d′.

Results
Systematic biases (P < 0.001) were observed between each pair of fitting procedures for CS and d′, even when comparing two statistically appropriate fitting procedures, though negligible, thus corroborating the hypothesis.

Conclusion
The differences suggest that a statistically appropriate fitting procedure should be chosen beforehand by the researcher. This is also important for coaches that need to prescribe training sessions to their athletes based on exercise intensity, and their choice should be maintained over the running seasons.

AbstractPurposeWe investigated the cardiovascular individual response to 6 weeks (3×/week) of work-matched within the severe-intensity domain (high-intensity interval training, HIIT) or moderate-intensity domain (moderate-intensity continuous training, MICT). In addition, we analyzed the cardiovascular factors at baseline underlying the response variability.Methods42 healthy sedentary participants were randomly assigned to HIIT or MICT. We applied the region of practical equivalence-method for identifying the levels of responders to the maximal oxygen uptake (V̇O2max) response. For investigating the influence of cardiovascular markers, we trained a Bayesian machine learning model on cardiovascular markers.ResultsDespite that HIIT and MICT induced significant increases in V̇O2max, HIIT had greater improvements than MICT (p < 0.001). Greater variability was observed in MICT, with approximately 50% classified as “non-responder” and “undecided”. 20 “responders”, one “undecided” and no “non-responders” were observed in HIIT. The variability in the ∆V̇O2maxwas associated with initial cardiorespiratory fitness, arterial stiffness, and left-ventricular (LV) mass and LV end-diastolic diameter in HIIT; whereas, microvascular responsiveness and right-ventricular (RV) excursion velocity showed a significant association in MICT.ConclusionOur findings highlight the critical influence of exercise-intensity domains and biological variability on the individual V̇O2maxresponse. The incidence of “non-responders” in MICT was one third of the group; whereas, no “non-responders” were observed in HIIT. The incidence of “responders” was 11 out of 21 participants in MICT, and 20 out of 21 participants in HIIT. The response in HIIT showed associations with baseline fitness, arterial stiffness, and LV-morphology; whereas, it was associated with RV systolic function in MICT.
Robust Policy in Times of Pandemic

Published: April 2021

AbstractThe pandemic exposes policymakers to fundamental uncertainties about future economic scenarios. While policymakers have to act forcefully to mitigate the impact on the economy, these conditions call for policy strategies that are also robust to uncertainty. This article compares two concepts of robust strategies: robust control and robust satisficing. It argues that a robust satisficing strategy is preferred and shows that the crisis responses of governments and central banks in Europe share features of robust satisficing in several dimensions.
Future themes of mathematics education research: an international survey before and during the pandemic
Authors: Bakker Arthur , Cai Jinfa , Zenger Linda 
Published: April 2021

AbstractBefore the pandemic (2019), we asked:On what themes should research in mathematics education focus in the coming decade?The 229 responses from 44 countries led to eight themes plus considerations about mathematics education research itself. The themes can be summarized as teaching approaches, goals, relations to practices outside mathematics education, teacher professional development, technology, affect, equity, and assessment. During the pandemic (November 2020), we asked respondents:Has the pandemic changed your view on the themes of mathematics education research for the coming decade? If so, how?Many of the 108 respondents saw the importance of their original themes reinforced (45), specified their initial responses (43), and/or added themes (35) (these categories were not mutually exclusive). Overall, they seemed to agree that the pandemic functions as a magnifying glass on issues that were already known, and several respondents pointed to the need to think ahead on how to organize education when it does not need to be online anymore. We end with a list of research challenges that are informed by the themes and respondents’ reflections on mathematics education research.

ZusammenfassungDie vorliegende Research Note stellt die erste systematische Dokumentation der Gesetzgebung in den deutschen Landtagen vor. Der Datensatz umfasst insgesamt 16.610 dokumentierte Gesetzgebungsvorgänge zwischen den Jahren 1990 und 2020. Nach einer Beschreibung des Datensatzes werden einige Gesetzgebungsmuster in den deutschen Ländern exemplarisch dargestellt. Die Landesgesetzgebung erweist sich dabei als stark durch den neuen Dualismus zwischen Regierung und Opposition geprägt. Im Initiativverhalten lassen sich zudem die Anreize des thematischen Parteienwettbewerbs ablesen. Wenig Evidenz findet sich für die These, dass innerkoalitionäre Gegensätze die Dauer der Gesetzgebungsverfahren in die Länge ziehen. Der mit dieser Research Note veröffentlichte Datensatz steht der Forschung für die Untersuchung zahlreicher weiterer Fragestellungen zur Verfügung.
Sliding Wear of Conventional and Suspension Sprayed Nanocomposite WC-Co Coatings: An Invited Review

Published: April 2021

AbstractThe global thermal spray coatings market was valued at USD 10.1 billion in 2019 and is expected to grow at a compound annual growth rate of 3.9% from 2020 to 2027. Carbide coatings form an essential segment of this market and provide cost-effective and environmental friendly tribological solutions for applications in aerospace, industrial gas turbine, automotive, printing, oil and gas, steel, and pulp and paper industries. Almost 23% of the world’s total energy consumption originates from tribological contacts. Thermal spray WC-Co coatings provide excellent wear resistance for industrial applications in sliding and rolling contacts. Some of these applications in abrasive, sliding and erosive conditions include sink rolls in zinc pots, conveyor screws, pump housings, impeller shafts, aircraft flap tracks, cam followers and expansion joints. These coatings are considered as a replacement of the hazardous chrome plating for tribological applications. The microstructure of thermal spray coatings is however complex, and the wear mechanisms and wear rates vary significantly when compared to cemented WC-Co carbides or vapour deposition WC coatings. This paper provides an expert review of the tribological considerations that dictate the sliding wear performance of thermal spray WC-Co coatings. Structure–property relationships and failure modes are discussed to grasp the design aspects of WC-Co coatings for tribological applications. Recent developments of suspension sprayed nanocomposite coatings are compared with conventional coatings in terms of performance and failure mechanisms. The dependency of coating microstructure, binder material, carbide size, fracture toughness, post-treatment and hardness on sliding wear performance and test methodology is discussed. Semiempirical mathematical models of wear rate related to the influence of tribological test conditions and coating characteristics are analysed for sliding contacts. Finally, advances for numerical modelling of sliding wear rate are discussed.

Published: April 2021

AbstractBusiness process simulation marks an essential technique for analyzing business processes and for reasoning about process improvement. With first contributions dating back to the mid-1990s, computerized business process simulation has been a continuing research focus and is widely acknowledged as foundational to Business Process Management research and practice. Reviewing contributions to the field published between 1990 and 2018, the authors assess the state of research on business process simulation and develop an organizing overview of research contributions discussing simulation approaches, tool support, results visualization, use context, application purposes, and adoption barriers. Findings inform future research on business process simulation by discussing paths for behavioral research on the use of business process simulation, user requirements, and adoption barriers as well as complementary paths for design science research addressing limitations of present approaches and simulation tool support.
Is the biological adaptiveness of delusions doomed?
Authors: Lancellotta Eugenia 
Published: April 2021

AbstractDelusions are usually considered as harmful and dysfunctional beliefs, one of the primary symptoms of a psychiatric illness and the mark of madness in popular culture. However, in recent times a much more positive role has been advocated for delusions. More specifically, it has been argued that delusions might be an (imperfect) answer to a problem rather than problems in themselves. By delivering psychological and epistemic benefits, delusions would allow people who face severe biological or psychological difficulties to survive in their environment - although this has obvious epistemic costs, as the delusion is fixed and irresponsive to compelling counterevidence. In other words, it has been argued that delusions are biologically adaptive. The adaptiveness of delusions has been compared by Ryan McKay and Daniel Dennett to a shear pin, a mechanism installed in the drive engine of some machines which is designed to shear whenever the machine is about to break down. By breaking, shear pins prevent the machine from collapsing and allow it to keep functioning, although in an impaired manner. Similarly, when delusions form, they would allow a cognitive or psychological system which is about to collapse to continue its functioning, although in an impaired manner. However, this optimistic picture of delusions risks being undermined by both theoretical and empirical considerations. Using Sarah Fineberg and Philip Corlett’s recent predictive coding account as a paradigmatic model of the biological adaptiveness of delusions, I develop two objections to it: (1) principles of parsimony and simplicity suggest that maladaptive models of delusions have an upper hand over adaptive models; and (2) the available empirical evidence suggests that at least some delusions stand good chances of being psychologically adaptive, but it is unlikely that they also qualify as biologically adaptive.
Experimental evaluation of the effect of soil water fluctuations in the dynamic behavior of machines

Published: April 2021

AbstractIn this study the dynamic response of a machine-foundation-soil system was investigated experimentally and theoretically. The objective of this work is to analyze the effects of the water table fluctuations in the soil on the response of the foundation and machine subjected to dynamic loads at frequencies ranging from 30 to 50 Hz. A physical model test was developed to simulate a machine-foundation-soil system, with measurements of the machine vibrations and the shear wave velocity of the soil. It is found that the water level produced significant changes in the shear wave velocity of the soil and, thus, in the natural frequencies of the system. For a fully saturated soil the vibration levels increased due to a working condition near resonance. The results showed a good agreement between the experimental vibration measurements and the predictions based on the theory used in foundation design, when considering the appropriate soil parameters. It is concluded that proper estimation of soil parameters is of high importance in the design process of machine foundations.
A time series assessment of terrestrial water storage and its relationship with hydro-meteorological factors in Gilgit-Baltistan region using GRACE observation and GLDAS-Noah model

Published: April 2021

AbstractMountains regions like Gilgit-Baltistan (GB) province of Pakistan are solely dependent on seasonal snow and glacier melt. In Indus basin which forms in GB, there is a need to manage water in a sustainable way for the livelihood and economic activities of the downstream population. It is important to monitor water resources that include glaciers, snow-covered area, lakes, etc., besides traditional hydrological (point-based measurements by using the gauging station) and remote sensing-based studies (traditional satellite-based observations provide terrestrial water storage (TWS) change within few centimeters from the earth’s surface); the TWS anomalies (TWSA) for the GB region are not investigated. In this study, the TWSA in GB region is considered for the period of 13 years (from January 2003 to December 2016). Gravity Recovery and Climate Experiment (GRACE) level 2 monthly data from three processing centers, namely Centre for Space Research (CSR), German Research Center for Geosciences (GFZ), and Jet Propulsion Laboratory (JPL), System Global Land Data Assimilation System (GLDAS)-driven Noah model, and in situ precipitation data from weather stations, were used for the study investigation. GRACE can help to forecast the possible trends of increasing or decreasing TWS with high accuracy as compared to the past studies, which do not use satellite gravity data. Our results indicate that TWS shows a decreasing trend estimated by GRACE (CSR, GFZ, and JPL) and GLDAS-Noah model, but the trend is not significant statistically. The annual amplitude of GLDAS-Noah is greater than GRACE signal. Mean monthly analysis of TWSA indicates that TWS reaches its maximum in April, while it reaches its minimum in October. Furthermore, Spearman’s rank correlation is determined between GRACE estimated TWS with precipitation, soil moisture (SM) and snow water equivalent (SWE). We also assess the factors, SM and SWE which are the most efficient parameters producing GRACE TWS signal in the study area. In future, our results with the support of more in situ data can be helpful for conservation of natural resources and to manage flood hazards, droughts, and water distribution for the mountain regions.

AbstractObjective:To determine whether the order in which healthcare workers perform patient care tasks affects hand hygiene compliance.Design:For this retrospective analysis of data collected during the Strategies to Reduce Transmission of Antimicrobial Resistant Bacteria in Intensive Care Units (STAR*ICU) study, we linked consecutive tasks healthcare workers performed into care sequences and identified task transitions: 2 consecutive task sequences and the intervening hand hygiene opportunity. We compared hand hygiene compliance rates and used multiple logistic regression to determine the adjusted odds for healthcare workers (HCWs) transitioning in a direction that increased or decreased the risk to patients if healthcare workers did not perform hand hygiene before the task and for HCWs contaminating their hands.Setting:The study was conducted in 17 adult surgical, medical, and medical-surgical intensive care units.Participants:HCWs in the STAR*ICU study units.Results:HCWs moved from cleaner to dirtier tasks during 5,303 transitions (34.7%) and from dirtier to cleaner tasks during 10,000 transitions (65.4%). Physicians (odds ratio [OR]: 1.50; P < .0001) and other HCWs (OR, 2.15; P < .0001) were more likely than nurses to move from dirtier to cleaner tasks. Glove use was associated with moving from dirtier to cleaner tasks (OR, 1.22; P < .0001). Hand hygiene compliance was lower when HCWs transitioned from dirtier to cleaner tasks than when they transitioned in the opposite direction (adjusted OR, 0.93; P < .0001).Conclusions:HCWs did not organize patient care tasks in a manner that decreased risk to patients, and they were less likely to perform hand hygiene when transitioning from dirtier to cleaner tasks than the reverse. These practices could increase the risk of transmission or infection.
Sexuality politics on the football field: queering the field in Turkey
Authors: Aktan Deniz Nihan 
Published: April 2021

AbstractFocusing on queer-identified amateur football teams, this article investigates the potentials of the mobilities and alliances of gender non-conforming footballing people to disrupt the seemingly effortless structure of the football field. While football is arguably one of the sports with the strongest discriminatory attitudes toward gender non-conforming people, it has also become a site of resistance for queers in Turkey as of 2015. How political opposition groups relate to the football field, which is mostly considered as a male-dominant and heterosexualized space where social norms are reproduced, are classified into three groups in my research: resistance through, against, and for football. I give particular attention to the category “resistance for football” as a distinctive way for gender non-conforming people to inhabit the field. I discuss how the link between sexual and spatial orientations shapes the domain of what a body can do, both in terms of normativity and capacity, and I explore what these teams offer in order to exceed spatial and sexual boundaries. Lastly, I present recent queer interventions in the value system of the game through which I reflect upon the concept of “queer commons” and the processes of bonding, belonging, and border-making in queer communities.
ERASMUS AND JUAN LUIS VIVES ON RHETORICALDECORUMAND POLITICS
Authors: HAVU KAARLO 
Published: April 2021

AbstractThe article analyses the emergence ofdecorum(appropriateness) as a central concept of rhetorical theory in the early sixteenth-century writings of Erasmus and Juan Luis Vives. In rhetorical theory,decorumshifted the emphasis from formulaic rules to their creative application in concrete cases. In doing so, it emphasized a close analysis of the rhetorical situation (above all the preferences of the audience) and underscored the persuasive possibilities of civil conversation as opposed to passionate, adversarial rhetoric. The article argues that the stress put ondecorumin early sixteenth-century theory is not just an internal development in the history of rhetoric but linked to far wider questions concerning the role of rhetoric in religious and secular lives.Decorumappears as a solution both to the divisiveness of language in the context of the Reformation and dynastic warfare of the early sixteenth century and as an adaptation of the republican tradition of political rhetoric to a changed, monarchical context. Erasmus and Vives maintained thatdecorumnot only suppressed destructive passions and discord, but that it was only through polite and civil rhetoric (or conversation) that a truly effective persuasion was possible in a vast array of contexts.
