Published: June 2021

Abstract
Objective
To examine the efficacy of reminder e-mails to continue yoga therapy on practice frequency and fatigue in cancer patients and long-term effects of yoga on fatigue, depression, and quality of life.

Methodology
One hundred two cancer patients who completed an 8-week yoga therapy were randomly allocated to two groups: reminder (N = 51) vs. no-reminder group (N = 51). After completing yoga therapy, the reminder group received weekly e-mails for 24 weeks, which reminded them of practicing yoga, whereas the no-reminder group did not. Primary outcomes were fatigue and practice frequency, and long-term outcomes were fatigue, depression, and quality of life. Data were assessed using questionnaires after yoga therapy (T1) and 6 months after completing yoga therapy (T2).

Result
A significantly stronger reduction of general (p = 0.038, d = 0.42) and emotional fatigue (p = 0.004, d = 0.59) and a higher increase of practice frequency (p = 0.015, d = 0.52) between T1 and T2 were found for the reminder group compared to the no-reminder group. In the mediation model, practice frequency as a mediator partially explained the changes in emotional fatigue (indirect effect B =  − 0.10). Long-term effects of yoga therapy regarding fatigue, depression, and quality of life were found (F > 7.46, p < 0.001, d > 0.54).

Conclusion
Weekly reminder e-mails after yoga therapy can positively affect general and emotional fatigue and help cancer patients with fatigue establish a regular yoga practice at home. However, higher practice frequency did not lead to higher physical or cognitive fatigue improvement, suggesting other factors that mediate efficacy on physical or cognitive fatigue, such as mindfulness or side effects of therapy.
Zugang zu urbanen Grünflächen im Kontext von Hitzeereignissen am Beispiel von Jena

Published: June 2021

ZusammenfassungDer Klimawandel und die bauliche Beschaffenheit von Städten führen zu zunehmenden Hitzeereignissen in Städten, die Auswirkungen auf Gesundheit und Wohlbefinden der Bewohner*innen haben können. Urbane Grünflächen werden als stadtplanerische Möglichkeit betrachtet, das Mikroklima innerhalb der Stadt zu beeinflussen und das Wohlbefinden der Bewohner*innen zu erhöhen. Bisherige Studien zeigen jedoch, dass diese Form der stadtplanerischen Klimaanpassung Fragen der sozialen Gerechtigkeit aufwirft: Nicht alle Bewohner*innen der Städte haben gleichen Zugang zu kühlenden Grünflächen. Ausgehend von der Frage, welche räumlichen Strategien vulnerable Gruppen bei Hitzeereignissen verfolgen, wird in diesem Beitrag analysiert, inwiefern es soziale oder räumliche Unterschiede im Zugang zu urbanen Grünflächen gibt. Als Fallbeispiel dient hier die Stadt Jena (Thüringen). Datengrundlage stellt eine systematische, teilstandardisierte Befragung der Bewohner*innen der besonders hitzebelasteten Stadtteile aus dem Jahr 2018 dar. In dieser Studie wird dezidiert die Perspektive, das Verhalten und die Bedarfe der Stadtbewohner*innen erhoben. Die Ergebnisse legen nahe, dass ältere Personen an heißen Tagen eher in ihrer Wohnung bzw. ihrem Haus bleiben und öffentliche Räume meiden. Dieser Rückzug kann zum sozialen Ausschluss dieser Bevölkerungsgruppe führen, wenn nicht stadtplanerisch reagiert wird. Kühlende Grünflächen sind zwar in Jena prinzipiell zahlreich vorhanden – allerdings ungleich verteilt, was sich am Nutzungsverhalten der Befragten widerspiegelt. Der von vulnerablen sozialen Gruppen bewohnte Norden der Stadt ist weitgehend abgeschottet von Grünflächen, die den Bedarfen der Befragten entsprechen. Der Beitrag spricht Handlungsempfehlungen für die Stadtentwicklung aus und beleuchtet, wie die Stadt Jena auf die Studie reagiert hat.
On methods and tools for rigorous system design

Published: June 2021

AbstractFull a posteriori verification of the correctness of modern software systems is practically infeasible due to the sheer complexity resulting from their intrinsic concurrent nature. An alternative approach consists of ensuring correctness by construction. We discuss the Rigorous System Design (RSD) approach, which relies on a sequence of semantics-preserving transformations to obtain an implementation of the system from a high-level model while preserving all the properties established along the way. In particular, we highlight some of the key requirements for the feasibility of such an approach, namely availability of (1) methods and tools for the design of correct-by-construction high-level models and (2) definition and proof of the validity of suitable domain-specific abstractions. We summarise the results of the extended versions of seven papers selected among those presented at the $$1\mathrm {st}$$

Published: June 2021

ZusammenfassungIm Schienenpersonenfernverkehr bestehen trotz Bahnstrukturreform weiterhin hohe Markteintrittsbarrieren. Der Wettbewerb im Nah- und Schienengüterverkehr ist im Vergleich dazu bereits besser in Gang gekommen. Die Autoren schlagen einen innovativen Regulierungsansatz vor, um den intramodalen Wettbewerb im Schienenpersonenfernverkehr zu beleben. Mitbewerbern der Deutschen Bahn soll nicht nur der offene Zugang zu Gleisen, sondern auch zu Zügen und Wagen — also Sitzplatzkontingenten — ermöglicht werden.
Digitale Integration — Chancen für kleine und mittelständische Unternehmen in Deutschland
Authors: Mesloh Melanie 
Published: June 2021

ZusammenfassungDie Nutzung digitaler Technologien zur Entwicklung innovativer Geschäftsmodelle und interner Prozesse bietet kleinen und mittelständischen Unternehmen die Möglichkeit, auf externe Veränderungen agil zu reagieren. Jedoch zeigt ein internationaler Vergleich der digitalen Wettbewerbsfähigkeit der EU28, dass Deutschland in diesem Bereich Nachholbedarfe hat. Um sich zukünftig im internationalen digitalen Wettbewerb positiv zu positionieren, bedarf es einer gestärkten digitalen Integration der kleinen und mittelständischen Unternehmen, die das Rückgrat der deutschen Wirtschaft bilden. Die bisherige digitale Integration wird untersucht, und die Vorteile und Barrieren der digitalen Integration werden hervorgehoben.
Surviving but not thriving: Comparing primary, vocational and higher education teachers’ experiences during the COVID-19 lockdown
Authors: Kovacs Helena , Pulfrey Caroline , Monnier Emilie-Charlotte 
Published: June 2021

AbstractIn this paper we examine the impacts of the global pandemic in 2020 on different levels of education system, particularly looking at the changes in teaching practice. The health emergency caused closure of schools, and online distance education became a temporary solution, creating discomfort for many teachers for whom this was the first time engaged with online education. In our research we investigated two important dimensions, namely, how technology was used and what the newfound distance meant in terms of the teacher-student relationship. The article offers insights into experiences of teaching from lockdown reported by 41 teachers at primary, vocational and higher education level in the region of Vaud, Switzerland. This comparative qualitative research has provided an opportunity for an in-depth analysis of the main similarities and differences at three distinctly different educational levels and a possibility to learn more about common coping practices in teaching. The study gives a contribution to a lack of comparative studies of teacher experiences at different educational levels. Results show two dimensions in handling the lockdown crisis: mastering the digital tools and the importance of student–teacher interaction. Whilst the interviewed teachers largely overcame the challenges of mastering digital tools, optimizing the quality interaction and ensuring the transactional presence online remained a problem. This indicates the importance of the social aspect in education at all levels, and implies that teacher support needs to expand beyond technical pedagogical knowledge of online distance education.
Academic engagement with industry: the role of research quality and experience
Authors: Scandura Alessandra , Iammarino Simona 
Published: June 2021

AbstractThis work explores the role of university department characteristics in academic engagement with industry. In particular, we investigate the role played by research quality and previous experience in academic engagement across different scientific disciplines. We test our hypotheses on a dataset of public sponsored university-industry partnerships in the United Kingdom, combined with data from the UK Research Assessment Exercises 2001 and 2008. Our analysis reveals a negative link between academic quality and the level of engagement with industry for departments in the basic sciences and a positive relationship for departments in the applied sciences. Our results further show that the role of research quality for academic engagement strictly depends on the level of the department’s previous experience in university-industry partnerships, notably in the basic sciences, where experience acts as a moderating factor. The findings of this work are highly relevant for policy makers and university managers and contribute to the innovation literature focused on the investigation of the determinants of valuable knowledge transfer practices in academia.
Disentangling nematode and arbuscular mycorrhizal fungal community effect on the growth of range-expanding Centaurea stoebe in original and new range soil
Authors: Koorem Kadri , Wilschut Rutger A. , Weser Carolin , van der Putten Wim H. 
Published: June 2021

Abstract
Aims
Numerous organisms show range expansions in response to current climate change. Differences in expansion rates, such as between plants and soil biota, may lead to altered interactions in the new compared to the original range. While plant-soil interactions influence plant performance and stress tolerance, the roles of specific soil organisms driving these responses remain unknown.

Methods
We manipulated the abundances of nematodes and arbuscular mycorrhizal fungi (AMF), collected from original and new range soils, and examined their effects on the biomass of range-expanding Centaurea stoebe and native Centaurea jacea. In the first approach, nematode and AMF communities were extracted from field soils, and inoculated to sterilized soil. In the second approach, the abundance of soil organisms in soil inocula was reduced by wet sieving; at first, plants were grown to condition the soil, and then plant-soil feedback was determined under ambient and drought conditions.

Results
The origin of soil communities did not influence the biomass production of range-expanding or native plant species, neither by addition nor by (partial) removal. However, after conditioning and under drought, range expanding C. stoebe produced more biomass with soil communities from the original range while C. jacea, native to both ranges, produced more biomass with new range soil communities.

Conclusions
We show that nematode and AMF communities from original and new range have similar effect on the growth of range expanding C. stoebe. Our results highlight that the effect of soil communities on plant growth increases after soil conditioning and under drought stress.
The indicator of a happy, long and sustainable life
Authors: Gaucher Renaud , Dialga Issaka , Vennin Coralie 
Published: June 2021

AbstractMany indicators are used to measure the quality of life of people and, consequently, these can be used to inform us about the quality of public policies. We propose to clarify this situation by asking one simple question: What is really important for us as an individual? This question can be asked to anyone and we could build a main indicator for public policies using this question and the responses of people. Our personal response is the following: What is really important for us as an individual is to live a happy and long life, and a life that does not prevent following generations from having lives as happy and long as ours, that is a sustainable life. We have built an indicator that fits this purpose. As we are negative utilitarianists and we consider that reducing premature deaths is more important than lengthening the duration of life, the indicator follows these two approaches. We give the cross-sectional results of the indicator of a happy, long and sustainable life, and we discuss the advantages and shortcomings of the indicator and avenues for future research.
Austrian economics without extreme apriorism: A critical reply
Authors: Lipski Jonas 
Published: June 2021

AbstractIn this paper I will analyze and criticize Linsbichler’s recent proposition to interpret the fundamental axiom of Praxeology as analytic. I will first describe Linsbichler’s problem situation. I will then describe and criticize Linsbichler’s proposed solution to his problem; namely his interpretation of the fundamental axiom as analytic. I will argue that this idea does not fully utilize critical potentials that are available to improve the fundamental axiom. I will propose an alternative interpretation which I call the ‘critical interpretation’ that conserves the progressive aspects of Linsbichler’s proposal while eliminating undesirable ones.
Small group forecasting using proportional-prize contests
Authors: Peeters Ronald , Rao Fan , Wolk Leonard 
Published: June 2021

AbstractWe consider a proportional-prize contest to forecast future events, and show that, in equilibrium, this mechanism possesses perfect forecasting ability for any group size when the contestants share common knowledge about the probabilities by which future events realize. Data gathered in a laboratory experiment confirm the performance invariance to group size. By contrast, when realization probabilities are not common knowledge, there are some differences across group sizes. The mechanism operates marginally better with three or four compared to two players. However, this effect is mainly driven by players’ behavior rather than by differences in the beliefs they form about the realization probabilities.
Effect of exergaming on wellbeing of residents in a nursing home: a single blinded intervention study
Authors: Gunst Marlies , De Meyere Isabelle , Willems Hannah , Schoenmakers Birgitte 
Published: June 2021

Abstract
Introduction
To improve the quality of life in nursing homes, meaningful activities and social contact are indispensable. Exergames can play a role addressing these needs.

Methods
In a randomized single blinded controlled intervention study, we investigated the effect of playing exergames on general wellbeing, fun and on social interaction.

Results
Thirty-five residents participated: 18 residents took part in the intervention group and 17 in the control group. The median mental wellbeing score of the intervention group increased from 42/50 to 45. The median sleep score of the intervention increased from 23/30 to 28. The median pain score of the intervention group improved from 18/20 to 20. The median score on subjective cognition increased from 24/30 to 26 while the mean scores on the objective assessment decreased from 1.8/2 to 1.7. Coaches gave an average fun score of 8.9/10 and an average intensity of exercise score of 11.6/20. Residents and coaches appreciated the social contact. Coaches reported a high feasibility (average of 4.1/5) but a low accessibility and a high intensity of supervision.

Conclusions
Exergaming is a feasible and pleasant complement to the usual activities with a positive impact on wellbeing, sleep, pain, and perceived cognition. Future research should focus on vulnerable groups and aim to develop a study in an implementation design.
Der Effekt von mobilen Luftfiltersystemen auf die Aerosolbelastung in Großraumszenarien vor dem Hintergrund des Infektionsrisikos der COVID-19-Erkrankung. Kann die Präsenzlehre wieder aufgenommen werden?
Authors: Oberst M. , Klar T. , Heinrich A. 
Published: June 2021

Zusammenfassung
Hintergrund
Vor dem Hintergrund der Corona-Pandemie wurde mit Beginn des Sommersemesters 2020 bundesweit die studentische Präsenzlehre praktisch eingestellt. Ebenso wurden im Rahmen des zweiten Lockdowns in vielen Bundesländern Schulen und Kindertagesstätten geschlossen bzw. auf ein Minimum heruntergefahren. In diesem Zusammenhang wurde bereits mehrfach der Effekt von Raumluftfiltern diskutiert, nach Ansicht des Umweltbundesamtes ist der Einsatz von mobilen Luftreinigern derzeit allerdings nicht empfohlen. Die vorliegende Untersuchung zeigt die konkreten Auswirkungen von mobilen Raumluftfiltern auf die Aerosolbelastung in einem Hörsaal, einer Kantine und einem schulischen Lernzentrum auf.

Methoden
In 3 Großräumen (studentischer Hörsaal, Betriebskantine, Lernzentrum eines Gymnasiums) wurde der Effekt von mobilen Raumluftfiltern (Fa. DEMA-airtech, Stuttgart) gemessen. Die Messungen der Aerosolkonzentrationen bzw. der CO2-Werte erfolgte mit Geräten der Firma Palas, Karlsruhe.

Ergebnisse
In allen 3 Szenarien zeigte sich übereinstimmend, dass die Aerosolkonzentration durch die Filter relevant und dauerhaft reduziert werden konnten. Der Effekt erschien teilweise sogar nachhaltiger und effektiver als beim normalen Stoßlüften.

Schlussfolgerung
Die Verwendung von Raumluftfiltern als ergänzende Maßnahme zum Abstandhalten und dem Tragen einer effektiven Mund-Nase-Bedeckung ist eine empfehlenswerte Maßnahme, die die Wiederaufnahme der Präsenzlehre ermöglichen könnte.
Time-periodic measures, random periodic orbits, and the linear response for dissipative non-autonomous stochastic differential equations
Authors: Branicki Michał , Uda Kenneth 
Published: June 2021

AbstractWe consider a class of dissipative stochastic differential equations (SDE’s) with time-periodic coefficients in finite dimension, and the response of time-asymptotic probability measures induced by such SDE’s to sufficiently regular, small perturbations of the underlying dynamics. Understanding such a response provides a systematic way to study changes of statistical observables in response to perturbations, and it is often very useful for sensitivity analysis, uncertainty quantification, and improving probabilistic predictions of nonlinear dynamical systems, especially in high dimensions. Here, we are concerned with the linear response to small perturbations in the case when the time-asymptotic probability measures are time-periodic. First, we establish sufficient conditions for the existence of stable random time-periodic orbits generated by the underlying SDE. Ergodicity of time-periodic probability measures supported on these random periodic orbits is subsequently discussed. Then, we derive the so-called fluctuation–dissipation relations which allow to describe the linear response of statistical observables to small perturbations away from the time-periodic ergodic regime in a manner which only exploits the unperturbed dynamics. The results are formulated in an abstract setting, but they apply to problems ranging from aspects of climate modelling, to molecular dynamics, to the study of approximation capacity of neural networks and robustness of their estimates.
Open-source Tools in R for Landscape Ecology

Published: June 2021

AbstractPurpose of ReviewLandscape ecology, the study of the complex interactions between landscapes and ecological processes, has hugely benefited from the increase in widely available open-source software in recent years. In particular, theRprogramming language provides a wealth of community developed tools for landscape ecology.Recent FindingsIn this paper, we examine existing packages for downloading, processing and visualisation of spatial data, as well as those specifically developed for spatial ecological analysis. Additionally, we outline the results of a survey ofRusers within the landscape ecology community.SummaryWe found that landscape ecologists are generally satisfied with the functionality available withinR, and that as a community they are continually further developing the functionality available. Suggested future developments include improvement of computation performance; additional methods for landscape characterisation such as surface metrics; and advanced, accessible visualisation tools.
Identifying complications and failure modes of innovative growing rod configurations using the (hybrid) magnetically controlled growing rod (MCGR) and the spring distraction system (SDS)
Authors: Lemans Justin V. C. , Tabeling Casper S. , Castelein René M. , Kruyt Moyo C. 
Published: June 2021

Abstract
Background
Magnetically controlled growing rods (MCGRs) offer non-invasive distractions in Early-Onset Scoliosis (EOS). However, implant-related complications are common, reducing its cost-effectiveness. To improve MCGRs functionality and cost-effectiveness, we often combine a single MCGR with a contralateral sliding rod (hybrid MCGR). Recently, we developed the spring distraction system (SDS) as an alternative, which provides continuous distraction forces through a helical spring. This study aims to identify complication rates and failure modes of EOS patients treated with either of these innovative systems.

Methods
This single-centre retrospective study included EOS patients treated with a (hybrid) MCGR or SDS between 2013 and 2018. Baseline demographics, and data regarding complications and implant growth were measured. Complication rate, complication profile, complication-free survival and implant growth were compared between groups.

Results
Eleven hybrid- and three bilateral MCGR patients (4.1-year follow-up) and one unilateral, eleven hybrid and six bilateral SDS patients (3.0-year follow-up) were included. Groups had similar age, sex, aetiology distribution, and pre-operative Cobb angle. Complication rate was 0.35 complications/patient/year for MCGR patients and 0.33 complications/patient/year for SDS patients. The most common complications were failure to distract (MCGR-group; 8/20 complications) and implant prominence (SDS-group; 5/18 complications). Median complication-free survival was 2.6 years, with no differences between groups (p = 0.673). Implant growth was significantly higher in the SDS-group (10.1 mm/year), compared to the MCGR-group (6.3 mm/year).

Conclusion
(Hybrid) MCGR and SDS patients have similar complication rates and complication-free survival. Complication profile differs between the groups, with frequent failure to distract leading to significantly reduced implant growth in (hybrid) MCGR patients, whereas SDS patients frequently exhibit implant prominence and implant kyphosis.
