Architecture of a time‐sensitive provisioning system for cloud‐native software
Authors: Venkateswaran Sreekrishnan , Bauskar Adwait , Sarkar Santonu 
Published: December 2021

AbstractApplication development paradigms and composition of technology services are decisively moving in the direction of hybrid and multi clouds. Enterprises are stitching new cloud‐native business models that leverage containerized multi‐tier microservice architecture, heterogeneity of cloud deployment models, and diversity of cloud providers. Scalability and resiliency are key components of this new world architecture, but these are also functions of the predictability of provisioning the underpinning compute instances on cloud. Thus, a major challenge to surmount before complex multicloud aware applications can be designed is the problem of unpredictable latencies associated with the provisioning of compute services on cloud. In the first part of this article, we develop a technique for time‐sensitive provisioning of virtual compute on demand, while also allowing deprovisioning on demand. Using the technique we propose, a cloud broker will be able to operate on a pool of reserved instances sourced from cloud providers and multiplex them profitably across cloud customers with associated provisioning time guarantees, but without usage commitment restrictions. We articulate this challenge in the form of theReserved Instance Allocation Problem(RIAP), which we first prove to be NP‐hard. We then design a heuristic‐based method to solve the intractable RIAP in polynomial time. We evaluate the effectiveness of our heuristic‐based mechanism through a combination of deep simulations and practical validation on mainstream public clouds. We demonstrate that our algorithm consistently yields a high profit‐to‐investment ratio for a broker who seeks to operate a commerce of virtual machines with time‐sensitive provisioning. In the second part of this article, we tackle the problem of unpredictable provisioning latencies in bare metal commerce. We build and evaluate an allocation model to calculate optimal supporting bare metal inventory to maximize cost‐sensitive fulfillment of bare metal provisioning requests in a time‐sensitive manner.

Zusammenfassung
Hintergrund
Die Häufigkeit von Suizidversuchen ist ein zentraler Indikator der psychischen Gesundheit der Bevölkerung und daher Gegenstand der Mental Health Surveillance am Robert Koch-Institut. Da bisher keine Datenquellen systematisch zur kontinuierlichen Erfassung von psychiatrischen Notfällen – zu denen Suizidversuche zählen – herangezogen werden, wird die Nutzung von Routinedaten aus Notaufnahmen zu diesem Zweck geprüft.

Methoden
Routinedaten aus 12 Notaufnahmen wurden für den Zeitraum 01.01.2018–28.03.2021 ausgewertet. Syndromdefinitionen für Suizidversuche, psychiatrische Notfälle und psychische Symptomatik wurden als Kombinationen aus Vorstellungsgründen und Diagnosen entwickelt. Fälle wurden alters- und geschlechtsspezifisch sowie im Zeitverlauf dargestellt.

Ergebnisse
Von insgesamt 1.516.883 Notaufnahmevorstellungen wurden 5133 (0,3 %) als Suizidversuche, 31.085 (2,1 %) als psychiatrische Notfälle und 34.230 (2,3 %) als Fälle mit einer psychischen Symptomatik identifiziert. 16,5 % der psychiatrischen Notfälle wurden so als Suizidversuch eingeschätzt. Unter den Suizidversuchen entfallen 53,4 % auf Männer und insgesamt 20,2 % auf die Altersgruppe der 25- bis 34-Jährigen. Alle 3 Syndromdefinitionen können über den gesamten Beobachtungszeitraum Fälle sowie deren zeitliche Variation abbilden.

Fazit
Notaufnahmedaten zeigen Potenzial zur syndromischen Surveillance von Suizidversuchen und psychiatrischen Notfällen und bieten damit einen Ausgangspunkt für weitere Validierung und Analyse. Die Abbildung von Veränderungen in Echtzeit erweitert die bisherigen Forschungsmöglichkeiten zu psychiatrischen Notfällen in Deutschland. Eine systematische Surveillance von Suizidversuchen kann zu einer evidenzbasierten Suizidprävention beitragen.
Einstellung der Allgemeinbevölkerung zur Schweigepflicht von Ärzt:innen und Psychotherapeut:innen bei Patient:innen mit extremistischer Einstellung
Authors: Rau Thea , Mayer Sophia , Fegert Jörg M. , Allroggen Marc 
Published: December 2021

Zusammenfassung
Hintergrund
Um extremistische Gewalttaten zu verhindern, wurde in der Vergangenheit immer wieder diskutiert, inwieweit eine allgemeine Aufhebung der ärztlichen Schweigepflicht und der Verschwiegenheitspflichten bei psychologischen Psychotherapeut:innen und Ärzt:innen im Zusammenhang mit extremistischen Einstellungen bei Patient:innen ein sinnvolles Mittel zur Gefahrenabwehr sei. Bislang gibt es keine Untersuchung darüber, ob dies im politischen Diskurs ein mehrheitsfähiges Argument ist, da es keine Befragung zur Einstellung der Allgemeinbevölkerung im Zusammenhang mit religiösem oder politischem Extremismus und Verschwiegenheitspflichten gibt.

Material und Methoden
Anhand einer bevölkerungsrepräsentativen Befragung (n = 2503) wurde die Einstellung der Allgemeinbevölkerung untersucht.

Ergebnisse
Es zeigt sich, dass über die Hälfte der Befragten (58 %) den Schutz vor möglicher Gefährdung durch extremistische Gewalt als wichtiger ansehen als die Einhaltung der Schweigepflicht bei Psychiater:innen und Psychotherapeut:innen. Über die Hälfte (54 %) stimmen dem zu, dass die Möglichkeit zum Bruch der Schweigepflicht grundsätzlich bestehen sollte, wenn Psychotherapeut:innen oder Psychiater:innen von extremistischen Einstellungen bei Patient:innen erfahren. Die Zustimmung war insbesondere dann höher, wenn die Befragten Terrorismus grundsätzlich in einen Zusammenhang mit psychischen Erkrankungen brachten.

Schlussfolgerung
Die Ergebnisse zeigen einerseits die Notwendigkeit, über die Bedeutung der Schweigepflicht als zentrale Grundlage einer Heilbehandlung stärker aufzuklären, andererseits aber auch sehr kritisch Stellung zu beziehen, welche Rolle psychische Erkrankungen tatsächlich bei der Entstehung von extremistischer Gewalt spielen, um eine Stigmatisierung von Betroffenen zu vermeiden.
Female breeding dispersal to higher quality habitats in a philopatric top predator

Published: December 2021

AbstractPhilopatry and monogamy are conventionally viewed as strategies for improving fitness. Many philopatric and monogamous species have, however, been shown to perform breeding dispersal—an exchange of territory (and often also partner) between two breeding seasons. The adaptiveness of breeding dispersal remains controversial, as data remain scarce and sporadic. For the Northern Goshawk, a typically highly philopatric and monogamous forest raptor, pairs breeding in barren forest landscapes produce fewer fledglings than pairs breeding in more productive landscapes. Using data on Finnish breeding female Goshawks (Accipiter gentilis) during 1999–2016, we tested the hypotheses that: (1) breeding dispersal is more likely at barren territories, (2) dispersing females move to less barren territories, and (3) breeding dispersal improves the survival of young. About 29% of the female Goshawks in our study performed breeding dispersal, which contrasts to philopatry and suggest that site and partner fidelities show large variation within the species’ breeding range. We found no evidence that territorial landscape barrenness (proxy on habitat quality) affects the probability of breeding dispersal. However, females that dispersed upgraded to less barren territories. Nevertheless, there were no subsequent effects of breeding dispersal on reproductive performance, suggesting no obvious difference in the capability of rearing young at either site. Although dispersal events were directed to less barren habitats, we suggest that female dispersal is not driven by the pursue for more prospersous habitats, rather that those females are forced to move, for whatever reason. In addition to other observed reasons such as female–female competition for mates and loss of the original mate, intense logging of mature forests lowering local food availability and restricting nest site availability were likely a partial cause of increased breeding dispersal.
Solidarity and The Politics of Redress: Structural Injustice, History and Counter-Finalities
Authors: Owen David 
Published: December 2021

AbstractThis paper examines Nuti’s accounts of structural injustice and historical injustice in the light of a political dilemma that confronted Young’s work on structure injustice. The dilemma emerges from a paradox that can be stated simply: justly addressing structural injustice would require that those subject to structural injustice enjoy the kind of privileged position of decision-making power that their being subject to structural injustice denies them. The dilemma thus concerns how to justly address structural injustice. I argue that Nuti’s account is currently unable to provide an adequate theorization of how to address this dilemma because it lacks an account of political solidarity, but also that her account provides important resources for dissolving a dispute between two competing theories of solidarity in a way that facilitates the articulation of an account of political solidarity that is adequate to addressing the political dilemma.
Perceived Vulnerability to Disease, Knowledge and Preventive Behavior Related to COVID-19 in Farsi and Arabic Speaking Refugees

Published: December 2021

AbstractIn the face of the worldwide COVIV-19 pandemic, refugees represent a particularly vulnerable group with respect to access to health care and information regarding preventive behavior. In an online survey the Perceived Vulnerability to Disease Scale, self-reported changes in preventive and risk behaviors, knowledge about COVID-19, and psychopathological symptoms (PHQ-4) were assessed. The convenience sample consisted of n = 76 refugees (n = 45 Arabic speaking, n = 31 Farsi speaking refugees) and n = 76 German controls matched with respect to age and sex. Refugees reported a significantly larger fear of infection, significantly less knowledge about COVID-19, and a higher frequency of maladaptive behavior, as compared to the control group. This study shows that refugees are more vulnerable to fear of infection and maladaptive behaviors than controls. Culturally adapted, easily accessible education about COVID-19 may be beneficial in improving knowledge and preventive behaviors related to COVID-19.
Teaching for Emergent Disciplinary Drawing in Science? Comparing Teachers’ and Children’s Ways of Representing Science Content in Early Childhood Classrooms
Authors: Areljung Sofie , Skoog Marianne , Sundberg Bodil 
Published: December 2021

AbstractThis classroom-based study aims to contribute knowledge about children’s opportunities to make use of drawing to make meaning in science. Employing a social semiotic approach to drawing, we examine what ways of representing science content that are (1) made available by the teacher and (2) adopted in children’s drawings. We analysed observation data from 11 science lessons in early childhood classrooms (children aged 3 to 8 years), including the drawings that children made during those lessons (129 drawings in total). Our findings suggest that the semiotic resources that teachers provide have a large impact on how children represent science content in their drawings. Moreover, we interpret that teachers strive to support children’s ‘emergent disciplinary drawing’ in science, since they predominantly provided semiotic resources where the science content was generalised and decontextualised. Finally, we propose that ‘emergent disciplinary drawing’ is incorporated as an element of science pedagogy in ECE practice and ECE teacher education.
A Semantics for Hyperintensional Belief Revision Based on Information Bases
Authors: Bozdag Sena 
Published: December 2021

AbstractI propose a novel hyperintensional semantics for belief revision and a corresponding system of dynamic doxastic logic. The main goal of the framework is to reduce some of the idealisations that are common in the belief revision literature and in dynamic epistemic logic. The models of the new framework are primarily based on potentially incomplete or inconsistent collections of information, represented by situations in a situation space. I propose that by shifting the representational focus of doxastic models from belief sets to collections of information, and by defining changes of beliefs as artifacts of changes of information, we can achieve a more realistic account of belief representation and belief change. The proposed dynamic operation suggests a non-classical way of changing beliefs: belief revision occurs in non-explosive environments which allow for a non-monotonic and hyperintensional belief dynamics. A logic that is sound with respect to the semantics is also provided.
A new look at Eccaparadoxides (Cambrian, Trilobita) and its biostratigraphic significance
Authors: Geyer Gerd , Landing Ed , Żylińska Anna 
Published: December 2021

AbstractEccaparadoxides is a geographically widely distributed trilobite genus that occurs in the middle part of the Cambrian System. However, the systematically important morphologic characteristics that can be used to differentiate taxa are often problematical in their application. A review of the large number (over 30) of significant species or forms assigned to Eccaparadoxides clearly indicates that only the pygidia offer fairly reliable morphologic criteria that can be used taxonomically and phylogenetically. The pygidia allow for recognition of four different morphological groups (pusillus, lamellatus, pradoanus and asturianus) of which the asturianus group can only be questionably assigned to the genus. Species known only from cranidia cannot be assigned to Eccaparadoxides with certainty. This study refines the biostratigraphy for the interval from the upper Wuliuan to the middle Drumian and shows that this interval brackets the range of most Eccaparadoxides species. The genera or subgenera Baltoparadoxides, Rejkocephalus and Macrocerca are evaluated. Eccaparadoxides zelus, E. epimetheus and Eccaparadoxides? hestia are newly proposed species.
When and How to Regulate: Everyday Emotion-Regulation Strategy Use and Stressor Intensity
Authors: Blanke Elisabeth S. , Bellingtier Jennifer A. , Riediger Michaela , Brose Annette 
Published: December 2021

AbstractContextual factors shape emotion regulation (ER). The intensity of emotional stimuli may be such a contextual factor that influences the selection and moderates the effectiveness of ER strategies in reducing negative affect (NA). Prior research has shown that, on average, when emotional stimuli were more intense, distraction was selected over reappraisal (and vice versa). This pattern was previously shown to be adaptive as the preferred strategies were more efficient in the respective contexts. Here, we investigated whether stressor intensity predicted strategy use and effectiveness in similar ways in daily life. We examined five ER strategies (reappraisal, reflection, acceptance, distraction, and rumination) in relation to the intensity of everyday stressors, using two waves of experience-sampling data (N = 156). In accordance with our hypotheses, reappraisal, reflection, and acceptance were used less, and rumination was used more, when stressors were more intense. Moreover, results suggested that distraction was more effective, and rumination more detrimental the higher the stressor intensity. Against our hypotheses, distraction did not covary with stressor intensity, and there was no evidence that reappraisal, reflection, and acceptance were more effective at lower levels of stressor intensity. Instead, when examined individually, reflection and reappraisal (like distraction) were more effective at higher levels of stressor intensity. In sum, stressor intensity predicted ER selection and moderated strategy effectiveness, but the results also point to a more complex ER strategy use in daily life than in the laboratory.
Losing Black Mothers, Finding Revolutionary Mothering
Authors: Hall K. Melchor Quick 
Published: December 2021

AbstractMy mother is losing her mother to Alzheimer's disease. Although my mother feels loss, I am connecting through my (maternal) grandmother to our ancestors, including a deceased father and paternal grandmother. I am also connecting to a daughter who has lost her mother, through a (maternal) grandmother who, through her loss of memory, is more open to kin networks than my mother. Through deepening connections to my maternal grandmother and to my daughter, I feel I am losing my mother. I look to revolutionary mothering as a way to reconnect shattered bonds and find lost mothers. This article honors the important work of Saidiya Hartman, Dorothy Roberts, and countless revolutionary mothers.

AbstractIntroduction:The aim of the study was to investigate mental health and conspiracy theory beliefs concerning COVID-19 among health care professionals (HCPs).Material and methods:During lockdown, an online questionnaire gathered data from 507 HCPs (432 females aged 33.86 ± 8.63 and 75 males aged 39.09 ± 9.54).Statistical analysis:A post-stratification method to transform the study sample was used; descriptive statistics were calculated.Results:Anxiety and probable depression were increased 1.5–2-fold and were higher in females and nurses. Previous history of depression was the main risk factor. The rates of believing in conspiracy theories concerning the COVID-19 were alarming with the majority of individuals (especially females) following some theory to at least some extend.Conclusions:The current paper reports high rates of depression, distress and suicidal thoughts in the HCPs during the lockdown, with a high prevalence of beliefs in conspiracy theories. Female gender and previous history of depression acted as risk factors, while the belief in conspiracy theories might act as a protective factor. The results should be considered with caution due to the nature of the data (online survey on a self-selected but stratified sample).
Case study on the dairy processing industries and their wastewater generation in Latvia
Authors: Ekka Basanti , Dejus Sandis , Juhna Talis 
Published: December 2021

AbstractThe objective of the research presented in this Research Communication was to access the environmental impact of the Latvian dairy industries. Site visits and interviews at Latvian dairy processing companies were done in order to collect site-specific data. This includes the turnover of the dairy industries, production, quality of water in various industrial processes, the flow and capacity of the sewage including their characteristic, existing practices and measures for wastewater management. The results showed that dairy industries in Latvia generated in total approximately 2263 × 103 m3 wastewater in the year 2019. The Latvian dairy effluents were characterized with high chemical oxygen demand (COD), biological oxygen demand (BOD) and total solids (TS). Few dairy plants had pre-treatment facilities for removal of contaminants, and many lacked onsite treatment technologies. Most facilities discharged dairy wastewater to municipal wastewater treatment plants. The current study gives insight into the Latvian dairy industries, their effluent management and pollution at Gulf of Riga due to wastewater discharge.
Household budget management and women’s position in peasant families in the Polish lands in the nineteenth and early twentieth centuries
Authors: Wilczyńska Elwira 
Published: December 2021

AbstractThis article attempts to answer the question about the position of women in Polish peasant families in the late nineteenth and early twentieth centuries based on the memoirs of rural women. Contrary to the claim that taking control over the household budget gave women more power on the farm, memoirs of peasant women show that it was rather an additional duty and responsibility. This problem mainly affected low-income families, where income from typically male activities was insufficient, so homemakers supported the family from the female part of the farm: gardening and dairy production. Thus, despite the decisive importance of women’s earnings for the household budget, their power in the family had only a symbolic dimension.
Unions and agricultural protests in inland Spain during the Transition: the example of Burgos province (1975–80)
Authors: Redondo-Cardeñoso Jesús-Ángel 
Published: December 2021

AbstractThis article analyses the creation of unions and the evolution of protests (demonstrations, tractor blockades) instigated by farmers in the province of Burgos, in the interior of northern Spain, during the period following the death of the dictator Francisco Franco known as the Transition (1975–80). The study uses press articles, documentation from the Civil Government and information gathered through personal interviews. The aim of the article is to show that the farmers of the interior of northern Spain – an electorally conservative region – also participated in the citizens’ protests that were the driving force behind the democratisation process in the country during the 1970s.
First experiences with Myval Transcatheter Heart Valve System in the treatment of severe pulmonary regurgitation in native right ventricular outflow tract and conduit dysfunction
Authors: Odemis Ender , Yenidogan Irem 
Published: December 2021

AbstractThe rate of morbidity and mortality related to pulmonary regurgitation and pulmonary stenosis are big concerns after the surgery for CHD. Percutaneous pulmonary valve implantation has been established as a less invasive technique compared to surgery with promising results according to long-term follow-up of the patients. There are only two approved valve options for percutaneous pulmonary valve implantation until now, which are Melody (Medtronic, Minneapolis, Minn, USA) and Sapien (Edwards Lifesciences, Irvine, Ca, USA). Both valves have limitations and do not cover entire patient population. Therefore, the cardiologists need more options to improve outcomes with fewer complications in a such promising area. Herein, we present a case series applying for pulmonary position in conduits and native right ventricular outflow tract of a new transcatheter valve system Myval ® which is designed for transcatheter aortic valve implantation procedures. This is the first patient series in which the use of Myvalv in dysfunctional right ventricular outflow tracts is described, after surgical repair of CHD.
