Compact Hankel Operators Between Distinct Hardy Spaces and Commutators
Authors: Leśnik Karol , Mleczko Paweł 
Published: October 2021

AbstractThe paper is devoted to the study of compactness of Hankel operators acting between distinct Hardy spaces generated by Banach function lattices. We prove an analogue of Hartman’s theorem characterizing compact Hankel operators in terms of properties of their symbols. As a byproduct we give an estimation of the essential norm of such operators. Furthermore, compactness of commutators and semicommutators of Toeplitz operators for unbounded symbols is discussed.

Abstract
Purpose
To evaluate the impact of testing asymptomatic cancer patients, we analyzed all tests for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) before and during radiotherapy at a tertiary cancer center throughout the second wave of the pandemic in Germany.

Methods
Results of all real-time polymerase chain reaction (RT-PCR) tests for SARS-CoV‑2 performed at our radio-oncology department between 13 October 2020 and 11 March 2021 were included. Clinical data and anamnestic information at the time of testing were documented and examined for (i) the presence of COVID-19-related symptoms and (ii) virus-related anamnesis (high-risk [prior positive test or contact to a positive tested person within the last 14 days] or low-risk [inconspicuous anamnesis within the last 14 days]).

Results
A total of 1056 SARS-CoV‑2 tests in 543 patients were analyzed. Of those, 1015 tests were performed in asymptomatic patients and 41 tests in patients with COVID-19-associated symptoms. Two of 940 (0.2%) tests in asymptomatic patients with low-risk anamnesis and three of 75 (4.0%) tests in asymptomatic patients with high-risk anamnesis showed a positive result. For symptomatic patients, SARS-CoV‑2 was detected in three of 36 (8.3%) low-risk and three of five (60.0%) high-risk tests.

Conclusion
To the best of our knowledge, this is the first study evaluating the correlation between individual risk factors and positivity rates of SARS-CoV‑2 tests in cancer patients. The data demonstrate that clinical and anamnestic assessment is a simple and effective measure to distinctly increase SARS-CoV‑2 test efficiency. This might enable cancer centers to adjust test strategies in asymptomatic patients, especially when test resources are scarce.
The effect of an infra-acetabular screw for anatomically shaped three-dimensional plate or standard plate designs in acetabulum fractures: a biomechanical analysis

Abstract
Background
Various plate shapes and implant configurations are used for stabilization of acetabulum fractures via anterior approaches. Little is known about the biomechanical stability of a two-dimensionally shaped “conventional” plate (“J-Plate”—JP) in comparison to three-dimensionally shaped plate configurations (3DP). In addition, the augmentary effect of an infra-acetabular lag-screw (IACS) fixation for anterior column and posterior hemi-transverse acetabulum fractures has not been clarified in comparison of JP and 3DP constructs. This study analyzed the difference between the biomechanical stability of JP compared to 3DP and the role of an IACS in a standardized acetabular fracture model in a single-leg stance loading configuration.

Methods
In an artificial bone substitute pelvis model (Synbone© Malans, Switzerland), a typical and standardized fracture pattern (anterior column and posterior hemi-transverse) was created with osteotomy jigs. After anatomic reduction the stabilization was performed using JP or 3DP. Eight pelvises per group were axially loaded in a single-leg stance model up to 400 N. After the load cycle, an additional infra-acetabular screw was placed and the measurement repeated. Fragment displacement was recorded by an optical tracking system (Optitrack Prime 13®, Corvallis, USA).

Results
In the pure placement, 3DP provided significantly superior stability when compared to JP. Augmentation of JP by IACS increased the stability significantly, up to the level of 3DP alone, whereas augmentation of the 3DP did not result in further increase of overall stability.

Conclusion
The anatomically shaped plate alone provides a superior biomechanical stability in fixation of an anterior column and posterior hemi-transverse fracture model. In a JP fixation the augmentation by IACS provides similar strength as the anatomically shaped 3DP. By use of the anatomically shaped 3DP the need of a clinically risky application of IACS might be avoidable.

The history of Abies pinsapo during the Holocene in southern Spain, based on pedoanthracological analysis
Authors: Pardo-Martínez Rubén , Gómez-Zotano José , Olmedo-Cobo José Antonio 
Published: October 2021

AbstractThe aim of this research is to reconstruct the ancient distribution area ofAbies pinsapoBoiss. (Spanish fir) in the Serranía de Ronda region, southern Spain, during the Holocene. The main method was pedoanthracological analysis, the study of non-archaeological charcoal found in natural soils. In this research a total of 37 soil excavations were done in several mountain ranges with potentially favourable places for firs to have grown in the past. Specific sites and places such as hillsides, endorheic basins (with no outflow), sinkholes, summits and mountain passes were selected on the basis of evidence from a range of different sources including ancient documents, pollen studies and species distribution models. The soil samples collected from these sites were prepared in the laboratory and the charcoal was identified and radiocarbon dated. Statistical and cartographic analyses were also done. The study revealed evidence of past populations ofAbiessp. in places where it is no longer found today. A total of 47 different chronologies were obtained from these sites with ages ranging between 9,931 calbpand 78 calbp. In addition, the wide variations in the charcoal values enabled us to make an initial estimate of the importance of ancient forest fires in different places in the Serranía de Ronda. When this information has been considered with all the other available data sources, it will be an essential resource for the efficient management of relict fir woods in southern Spain.

Published: October 2021

ZusammenfassungDas Resources Innovation Center Leoben (RIC Leoben) an der Montanuniversität bündelt heute die internationalen Beteiligungen der Institution im Bereich der Nachhaltigkeit in Rohstoffforschung und Ausbildung. Das RIC geht zurück auf das Jahr 2015, wo es als Regional Center des EIT RawMaterials, einer Knowledge & Innovation Community des European Institute for Innovation and Technology, einem europäischen Netzwerk aus mittlerweile rund 300 Partnern des Rohstoffsektors, gegründet wurde. Besonders in den Bereichen Bildung, Sustainable Exploration & Mining, Technological Innovation und Recycling sowie der strategischen Weiterentwicklung und Mitgestaltung der Community ist die Montanuniversität durch das RIC hier tätig. 2017 wurden die Aktivitäten um die Mitgliedschaft in der EIT Climate-KIC, einer weiteren Knowledge & Innovation Community, erweitert, in der die Themen Urban Transitions und Sustainable Production Systems vorangetrieben werden, um die Auswirkungen des Klimawandels zu begrenzen und eine klimaresiliente Gesellschaft zu fördern. Ein zusätzlicher Bereich im Portfolio des RIC Leoben sind die Sustainable Development Goals der Vereinten Nationen, zu denen durch vielerlei Initiativen beigetragen wird. Eine Schlüsselaktivität in diesem Bereich ist die Implementierung ebendieser im österreichischen Hochschulsektor durch ein gemeinsames Netzwerk aller österreichischen Universitäten und die Übernahme einer Patenschaft für SDG 12. Die Aktivitäten des RIC haben auch zur inhaltlichen Gestaltung der European University on Responsible Consumption and Production beigetragen, die erfolgreich im Lead aus dem RIC heraus gegründet wurde. Ebenso bündelt das RIC die Wasserstoff- und Kohlenstoffaktivitäten der Universität. Allen Arbeiten im Resources Innovation Center Leoben ist eines gemein: Sie sind thematisch verknüpft und ergänzen sich. Die Resultate zielen alle auf nachhaltige Innovation im Ressourcenbereich für eine bessere Zukunft ab.
Sorting in an urban housing market—is there a response to demographic change?
Authors: Neumann Uwe , Taruttis Lisa 
Published: October 2021

AbstractUsing Dortmund as a case study we analyse whether rents and housing prices responded to local demographic change in a German city between 2007 and 2016. In a two-step analysis based on a spatial autoregressive hedonic pricing model and a discrete choice model of housing location we find that during the study period as a whole, higher local mortality induced a negative effect on apartment prices and rents. Yet, the neighbourhood effects of local ageing vary across sub-city districts. Most prominently, the study period was characterised by a strong and rising desire to purchase or rent housing in the vicinity of the city centre. Furthermore, prices for owner-occupied apartments and houses increased rapidly in the more well-off southern part of the city and particularly in a previously declining community, where a large-scale urban regeneration and environmental upgrading project has been implemented since 2011. The characteristics of households likely to move to this neighbourhood switched from low to high income.

Published: October 2021

ZusammenfassungAkut symptomatische Anfälle sind definiert durch einen engen zeitlichen Zusammenhang zwischen einem akuten Ereignis, welches einen negativen Einfluss auf das Gehirn hat, und dem daraus resultierenden Auftreten von epileptischen Anfällen. Diesem akuten Ereignis können neben einer strukturellen Hirnschädigung (z. B. traumatisch, vaskulär) unter anderem auch Entgleisungen im Rahmen internistischer Erkrankungen oder Einfluss von externen Noxen wie Medikamenten, Alkohol oder Drogen zugrunde liegen. In weiterer Folge beschreiben wir die häufigsten internistischen Ursachen, welche zu akut symptomatischen Anfällen führen können. Das Risiko von Elektrolytentgleisungen, Leber- und Nierenerkrankungen, Darmerkrankungen, Diabetes mellitus und der Einfluss unterschiedlicher Medikamente wird diskutiert.
A Study of Woven Fabrics Made of Helical Auxetic Yarns
Authors: Gao Yajie , Chen Xiaogang 
Published: October 2021

AbstractThe paper presents a study on woven fabrics made of helical auxetic yarns (HAYs) and their key factors on Poisson’s ratio under tension. The work aims to create and evaluate auxetic woven fabrics with optimal parameters for achieving better auxeticity including weave structure, wrapping angle of the auxetic yarn, thickness of the auxetic yarn and properties of the warp yarn. The maximum negative Poisson’s ratio (NPR) of the woven fabric can be achieved as low as -2.92 for experiments. Then, a numerical study has been carried out as well to assist the development of auxetic woven fabrics. The findings of this paper showed longer float length, lower wrapping angle of the auxetic yarn, a thinner diameter of the auxetic yarn as well as lower tensile modulus of the warp yarn led to higher auxetic behaviour. This can also provide a reference for researchers to select the best parameters for producing the auxetic woven fabrics.
Police Officers Do Not Need More Training; But Different Training. Policing Domestic Violence and Abuse Involving Children: A Rapid Review
Authors: Millar Annemarie , Saxton Michael , Øverlien Carolina , Elliffe Ruth 
Published: October 2021

AbstractAlthough the police have been identified as a key service provider when responding to domestic violence and abuse (DVA), very few studies have investigated their response in relation to children. This review aims to examine children’s experiences of police response in the context of DVA and to explore how the police understand and respond to children living with DVA. A rapid review of the empirical literature on the police response to DVA involving children was undertaken. PsycINFO, Web of Science and ProQuest were searched. Studies with a qualitative element, concerning children under 18 with experience of police involvement, or police experiences of children, in the context of DVA were included. The final sample comprised of six studies. Using reflexive thematic analysis, four key themes emerged in relation to children: children’s experiences of DVA; fear, uncertainty, and mistrust of police; confronting “childism”: a matter of children’s rights; and going beyond empathy: equality and justice. Regarding the police, three key themes emerged: variability in police response; limited view of police role; lack of professional competence. The findings underscore the need for awareness raising and an urgent review of the training officers receive regarding the impact of DVA on children. They also highlight the pivotal role of police when responding to DVA where children are present, as well as to advance the frontiers of research by including not only adults and professionals but also the most vulnerable DVA victim: the child.
In Utero Exposure to trans-10, cis-12 Conjugated Linoleic Acid Modifies Postnatal Development of the Mammary Gland and its Hormone Responsiveness

Published: October 2021

AbstractWe previously showed that dietary trans-10, cis-12 conjugated linoleic acid (10,12 CLA) stimulates estrogen-independent mammary growth in young ovariectomized mice. Here we investigated the effects of in utero or postnatal exposure to cis-9, trans-11 (9,11 CLA) and 10,12 CLA on postnatal development of the mammary gland and its responsiveness to ovarian steroids. In the first experiment we fed dams different CLA prior to and during gestation, then cross fostered female pups onto control fed dams prior to assessing the histomorphology of their mammary glands. Pregnant dams in the second experiment were similarly exposed to CLA, after which their female pups were ovariectomized then treated with 17β-estradiol (E), progesterone (P) or E + P for 5 days. In a third experiment, mature female mice were fed different CLA for 28 days prior to ovariectomy, then treated with E, P or E + P. Our data indicate that 10,12 CLA modifies the responsiveness of the mammary glands to E or E + P when exposure occurs either in utero, or postnatally. These findings underline the sensitivity of the mammary glands to dietary fatty acids and reinforce the potential for maternal nutrition to impact postnatal development of the mammary glands and their risk for developing cancer.
Long-Term Demographic Trends in Prehistoric Italy: Climate Impacts and Regionalised Socio-Ecological Trajectories

Published: October 2021

AbstractThe Italian peninsula offers an excellent case study within which to investigate long-term regional demographic trends and their response to climate fluctuations, especially given its diverse landscapes, latitudinal range and varied elevations. In the past two decades, summed probability distributions of calibrated radiocarbon dates have become an important method for inferring population dynamics in prehistory. Recent advances in this approach also allow for statistical assessment of spatio-temporal patterning in demographic trends. In this paper we reconstruct population change for the whole Italian peninsula from the Late Mesolithic to the Early Iron Age (10,000–2800 cal yr BP). How did population patterns vary across time and space? Were fluctuations in human population related to climate change? In order to answer these questions, we have collated a large list of published radiocarbon dates (n = 4010) and use this list firstly to infer the demographic trends for the Italian peninsula as a whole, before addressing each of five sub-regions in turn (northern, central, and southern Italy, Sicily, Sardinia). We also compare population fluctuations with local paleoclimate proxies (cave, lake, marine records). At a pan-regional scale, the results show a general rapid and substantial increase in population in the Early Neolithic with the introduction of farming at around 8000 cal yr BP and further dramatic increases during the Bronze and Iron Age (~ 3800–2800 cal yr BP). However, different regional demographic trajectories exist across different regions of Italy, suggesting a variety of localised human responses to climate shifts. Population and climate appear to have been more closely correlated during the early–mid Holocene (Mesolithic–Neolithic), while later in the Holocene (Bronze–Iron Ages) they decouple. Overall, across the Holocene the population dynamics varied by region and depended on the long-term socio-ecological dynamics prevailing in a given area. Finally, we include a brief response to the paper ‘Radiocarbon dated trends and central Mediterranean prehistory’ by Parkinson et al. (J Word Prehist 34(3), 2021)—synchronously published byJournal of World Prehistorybut wholly independently developed—indicating how our conclusions accord with or differ from one another.

Published: October 2021

AbstractPurposeFew studies have examined specific cognitive and behavioural responses to symptoms, which may impact health-related outcomes, in conjunction with illness representations, as outlined by the Common-Sense-Model. Patients with atrial fibrillation (AF) report poor quality-of-life (QoL) and high distress. This cross-sectional study investigated patterns/clusters of cognitive and behavioural responses to illness, and illness perceptions, and relationships with QoL, depression and anxiety.MethodsAF patients (N = 198) recruited at cardiology clinics completed the AF-Revised Illness Perception Questionnaire, Atrial-Fibrillation-Effect-on-Quality-of-Life Questionnaire, Patient Health Questionnaire-8 and Generalized Anxiety Disorder Questionnaire. Cluster analysis used Ward’s andK-means methods. Hierarchical regressions examined relationships between clusters with QoL, depression and anxiety.ResultsTwo clusters of cognitive and behavioural responses to symptoms were outlined; (1) ‘high avoidance’; (2) ‘low symptom-focussing’. Patients in Cluster 1 had lower QoL (M = 40.36, SD = 18.40), greater symptoms of depression (M = 7.20, SD = 5.71) and greater symptoms of anxiety (M = 5.70, SD = 5.90) compared to patients in Cluster 2 who had higher QoL (M = 59.03, SD = 20.12), fewer symptoms of depression (M = 3.53, SD = 3.56) and fewer symptoms of anxiety (M = 2.56, SD = 3.56).Two illness representation clusters were outlined; (1) ‘high coherence and treatment control’, (2) ‘negative illness and emotional representations’. Patients in Cluster 2 had significantly lower QoL (M = 46.57, SD = 19.94), greater symptoms of depression (M = 6.12, SD = 5.31) and greater symptoms of anxiety (M = 4.70, SD = 5.27), compared with patients in Cluster 1 who had higher QoL (M = 61.52, SD = 21.38), fewer symptoms of depression (M = 2.85, SD = 2.97) and fewer symptoms of anxiety (M = 2.16, SD = 3.63).Overall, clusters of cognitive and behavioural responses to symptoms, and illness perceptions significantly explained between 14 and 29% of the variance in QoL, depression and anxiety.ConclusionPatterns of cognitive and behavioural responses to symptoms, and illness perceptions are important correlates of health-related outcomes in AF patients.
On the Trail of Spatial Patterns of Genetic Variation
Authors: Peña José A. , Gómez-Pérez Luis , Alfonso-Sánchez Miguel A. 
Published: October 2021

AbstractThe accurate determination of the spatial trends on the variability of a species’ gene pool is essential to elucidate the underlying demographic-evolutionary events, thus helping to unravel the microevolutionary history of the population under study. Herein we present a new software called GenoCline, mainly addressed to detect genetic clines from allele, haplotype, and genome-wide data. This program package allows identifying the geographic orientation of clinal genetic variation through a system of iterative rotation of a virtual coordinate axis. Besides, GenoCline can perform complementary analyses to explore the potential origin of the genetic clines observed, including spatial autocorrelation, isolation by distance, centroid method, multidimensional scaling and Sammon projection. Among the advantages of this software is the ease in data entry and potential interconnection with other programs. Genetic and geographic data can be entered in spreadsheet table formatting (.xls), whereas genome-wide data can be imported in Eigensoft format. Genetic frequencies can also be exported in a format compatible with other programs dealing with population genetic and evolutionary biology analyses. All illustrations of results are saved in.svg format so that there will be high quality and easily editable vectorial graphs available for the researcher. Being implemented in Java, GenoCline is highly portable, thus working in different operating systems.

ZusammenfassungDas Projekt Agequake II erhob Daten zur psychischen Gesundheit älterer inhaftierter Personen in der Schweiz, evaluierte die aktuelle Situation deren psychiatrischer Versorgung und untersuchte Optionen zu ethischen, rechtlichen und wirtschaftlichen Lösungen in Bezug auf altersbedingte Probleme. Agequake, benannt nach dem Phänomen der rapide wachsenden Anzahl älterer inhaftierter Personen, ist somit eines der wenigen Forschungsprojekte, das Daten zu der älteren Gefängnispopulation liefert und Ergebnisse zur Erweiterung des Wissens über diese wenig erforschte Gruppe beisteuert. Die Ergebnisse tragen zum besseren Verständnis der Lebensrealitäten gefangener älterer Personen bei, bieten Strategien zur Verbesserung derer physischer und psychischer Gesundheitsversorgung und zur Verringerung der Belastung des Gefängnispersonals und der größeren Öffentlichkeit.
Professionelle polizeiliche Kommunikation: sich verstehen
Authors: Staller Mario S. , Koerner Swen , Zaiser Benjamin 
Published: October 2021

ZusammenfassungAuch wenn, einem Bonmot Watzlawicks folgend, nicht nicht kommuniziert werden kann, kann Kommunikation gleichwohl mehr oder weniger viel Aufmerksamkeit zuteilwerden. In den modernen Sozialwissenschaften ist Kommunikation längst theoretisch und empirisch zum Schlüsselelement komplexitätsangemessener Beschreibungen und Erklärungen moderner Gesellschaftsvollzüge avanciert. In der modernen Polizeiarbeit hat der aktuelle Wissensbestand zur Kommunikation diesen Anspruch noch nicht erreicht. Der Beitrag setzt hier an, indem er polizeiliche Kommunikation als zentrales Medium von Polizei-Bürger*innen-Interaktionen pragmatistisch modelliert. Demensprechend hat die Polizei in ihrer Kommunikation dem der Öffentlichkeit geschuldeten Maß an Professionalität gerecht zu werden. Diese, so unser zentrales Argument, zeigt sich als Kontrolle durch Einsicht in potenziell „blinde Flecken“ polizeilicher Kommunikation.
