Understanding the Mechanisms of Intergenerational Social Inequality in Demographic Behavior
Authors: Hiekel Nicole 
Published: April 2021

AbstractIn this chapter I contrast the economic and cultural perspective of intergenerational transmission processes of social inequality in demographic behavior. I systematically compile the underlying social mechanisms that are scattered across the literature and apply them to the relationships investigated within the CONOPP project. Identifying a predominant focus on the parental resource perspective in the literature linking family background and young adult demographic behavior, I argue in favor of widening the theoretical perspective. Greater theoretical width will enable social scientists to more comprehensively grasp the persistent social stratification of demographic behavior across generations and the role of context in moderating these relationships. I conclude with some suggestions on how future research can further push the boundaries of understanding these relationships.
Product Eco-Design in the Era of Circular Economy: Experiences in the Design of Espresso Coffee Machines

Published: April 2021

AbstractProduct eco-design includes several methodologies aimed at supporting companies in the development of sustainable products. Currently, this theme is assuming an important role in both the academia and industry worlds due to the increasing attention to environmental problems and the need for a transition toward circular economy business/organizational models. In this context, the present paper focuses on the industrial sector of espresso coffee machines manufacturing which has several unexploited potentialities. The analysis of the sector specificity (internal and external contexts), as well as of the product lifecycle allowed to define an eco-design framework to guide companies involved in the design and production of espresso coffee machines. Effective eco-design strategies should include the combined use of specific methods, tools and metrics to manage all the most important lifecycle phases (beginning of life, middle of life, end of life) during the design activities in order to set preventive actions that avoid future potential environmental impacts. Only in this way, the environmental and economic benefits of the circular economy paradigm (e.g. remanufacturing/reuse of selected components) can be practically exploited in real industrial contexts. The presented case studies confirmed that the application of design for disassembly rules positively contributes to increase the product performances during maintenance and end of life, while a re-design oriented to component modularity could be a key strategy to pursue remanufacturing for boilers, a key and expensive component included in espresso coffee machines.

Abstract
We present the leading colour and light fermionic planar two-loop corrections for the production of two photons and a jet in the quark-antiquark and quark-gluon channels. In particular, we compute the interference of the two-loop amplitudes with the corresponding tree level ones, summed over colours and polarisations. Our calculation uses the latest advancements in the algorithms for integration-by-parts reduction and multivariate partial fraction decomposition to produce compact and easy-to-use results. We have implemented our results in an efficient C++ numerical code. We also provide their analytic expressions in Mathematica format.
Mehr Evidenzbasierung in Prävention und Gesundheitsförderung: Kriterien für evidenzbasierte Maßnahmen und notwendige organisationale Rahmenbedingungen und Kapazitäten
Authors: De Bock Freia , Rehfuess Eva 
Published: April 2021

ZusammenfassungFür die Umsetzung des Präventionsgesetzes in einem sich entwickelnden System Prävention und Gesundheitsförderung (PGF) ist die Anforderung der Evidenzbasierung formuliert. Vor diesem Hintergrund stellt sich die Frage, welche Schritte, Prozesse und Vorgehensweisen in diesem System benötigt werden, um der Anforderung zunehmend gerecht zu werden. Dieser Übersichtsartikel diskutiert für Deutschland, wie evidenzbasierte Maßnahmen in der Praxis operationalisiert werden können und welche organisationalen Rahmenbedingungen und Kapazitäten für ein evidenzbasiertes Handeln von AkteurInnen notwendig sind.Aufbauend auf internationalen wissenschaftlichen Erkenntnissen und dem Memorandum Evidenzbasierte Prävention und Gesundheitsförderung der Bundeszentrale für gesundheitliche Aufklärung (BZgA) wird zunächst das Verständnis von evidenzbasierten Maßnahmen erläutert und im Weiteren werden Elemente zur Umsetzung von mehr Evidenzbasierung skizziert.Neben der transparenten und einheitlichen Darstellung in Datenbanken und Empfehlungen ist es notwendig, bei EntscheidungsträgerInnen in Praxis und Politik ein gemeinsames Verständnis von evidenzbasierten Interventionen und von Anforderungen für eine Evaluation, die Evidenzbasierung sichert, zu schaffen. Darüber hinaus kann evidenzbasiertes Handeln von EntscheidungsträgerInnen gefördert werden durch Wertschätzung gegenüber Evidenzbasierung in ihren Organisationen, durch Gewährleistung eines regelhaften Zugangs zu Evidenzdatenbanken, durch verbesserte Kompetenzen in Bezug auf Interpretation von Evidenz und durch eine systematische Zusammenarbeit mit der Wissenschaft.Mehr Evidenzbasierung ist eine Voraussetzung für die nachhaltige Verankerung von PGF als fünfte Säule des Gesundheitssystems.

ZusammenfassungHintergrundDie Behandlung periprothetischer Hüftinfektionen ist meist kostenintensiv und gilt im Allgemeinen als nicht kostendeckend für die Kliniken. Bei chronischen Infektionen ist oft ein zweizeitiger Prothesenwechsel indiziert, der als Fast-Track mit kurzem prothesenfreiem Intervall (2–4 Wochen) oder als Slow-Track mit langem prothesenfreiem Intervall (über 4 Wochen) erfolgen kann.ZielZiel dieser Arbeit war die Erfassung der Erlössituation beider Behandlungsformen im aktuellen aG-DRG-System 2020 unter Berücksichtigung erlösrelevanter Einflussfaktoren.MethodenFür Fast-Track und Slow-Track bei zweizeitigem septischem Hüftprothesenwechsel mit Nachweis eines Staphylococcus aureus (MSSA) wurden mittels einer Grouper-Software (3M KODIP Suite) anhand der Diagnosen (ICD-10-GM) und Prozeduren (OPS) Behandlungsfälle simuliert und in DRG eingruppiert. Erlösrelevante Parameter wie Verweildauer (VWD) und Nebendiagnosen (ND) wurden berücksichtigt. Zusätzlich wurden zwei reale Behandlungsfälle mit Fast-Track und Slow-Track miteinander verglichen.ErgebnisseDie Gesamterlöse betrugen beim Slow-Track bei einer VWD von 25 Tagen (ohne ND) 27.551 € und bei einer VWD von 42 Tagen (mit ND) 40.699 €. Beim Fast-Track hingegen lag der Gesamterlös bei 23.965 € bei einer VWD von 25 Tagen (ohne ND) und bei 27.283 € bei einer VWD von 42 Tagen (mit ND). Bei den realen Behandlungsfällen zeigte sich ebenfalls eine deutliche Differenz des Gesamterlöses von 12.244 € zugunsten des Slow-Tracks.DiskussionAuch im aG-DRG-System 2020 scheint der zweizeitige Hüftprothesenwechsel mit langem Interimsintervall insbesondere bei multimorbiden Patienten aus Krankenhaussicht ökonomisch vorteilhafter zu sein als das Fast-Track-Konzept, wodurch ein finanzielles Hemmnis zur Behandlung solcher Patienten mit kurzem Interimsintervall geschaffen wird.
The wizard and I: How transparent teleoperation and self-description (do not) affect children’s robot perceptions and child-robot relationship formation
Authors: van Straten Caroline L. , Peter Jochen , Kühne Rinaldo , Barco Alex 
Published: April 2021

AbstractIt has been well documented that children perceive robots as social, mental, and moral others. Studies on child-robot interaction may encourage this perception of robots, first, by using a Wizard of Oz (i.e., teleoperation) set-up and, second, by having robots engage in self-description. However, much remains unknown about the effects of transparent teleoperation and self-description on children’s perception of, and relationship formation with a robot. To address this research gap initially, we conducted an experimental study with a 2 × 2 (teleoperation: overt/covert; self-description: yes/no) between-subject design in which 168 children aged 7–10 interacted with a Nao robot once. Transparency about the teleoperation procedure decreased children’s perceptions of the robot’s autonomy and anthropomorphism. Self-description reduced the degree to which children perceived the robot as being similar to themselves. Transparent teleoperation and self-description affected neither children’s perceptions of the robot’s animacy and social presence nor their closeness to and trust in the robot.
Improving AR-powered remote assistance: a new approach aimed to foster operator’s autonomy and optimize the use of skilled resources

Published: April 2021

AbstractAugmented reality (AR) has a number of applications in industry, but remote assistance represents one of the most prominent and widely studied use cases. Notwithstanding, although the set of functionalities supporting the communication between remote experts and on-site operators grew over time, the way in which remote assistance is delivered has not evolved yet to unleash the full potential of AR technology. The expert typically guides the operator step-by-step, and basically uses AR-based hints to visually support voice instructions. With this approach, skilled human resources may go under-utilized, as the time an expert invests in the assistance corresponds to the time needed by the operator to execute the requested operations. The goal of this work is to introduce a new approach to remote assistance that takes advantage of AR functionalities separately proposed in academic works and commercial products to re-organize the guidance workflow, with the aim to increase the operator’s autonomy and, thus, optimize the use of expert’s time. An AR-powered remote assistance platform able to support the devised approach is also presented. By means of a user study, this approach was compared to traditional step-by-step guidance, with the aim to estimate what is the potential of AR that is still unexploited. Results showed that with the new approach it is possible to reduce the time investment for the expert, allowing the operator to autonomously complete the assigned tasks in a time comparable to step-by-step guidance with a negligible need for further support.

AbstractKnowledge
about the vegetation history of Sardinia, the second largest island of the Mediterranean, is scanty. Here, we present a new sedimentary record covering the past ~ 8,000 years from Lago di Baratz, north-west Sardinia. Vegetation and fire history are reconstructed by pollen, spores, macrofossils and charcoal analyses and environmental dynamics by high-resolution element geochemistry together with pigment analyses. During the period 8,100–7,500 cal bp, when seasonality was high and fire and erosion were frequent, Erica arborea and E. scoparia woodlands dominated the coastal landscape. Subsequently, between 7,500 and 5,500 cal bp, seasonality gradually declined and thermo-mediterranean woodlands with Pistacia and Quercus ilex partially replaced Erica communities under diminished incidence of fire. After 5,500 cal bp, evergreen oak forests expanded markedly, erosion declined and lake levels increased, likely in response to increasing (summer) moisture availability. Increased anthropogenic fire disturbance triggered shrubland expansions (e.g. Tamarix and Pistacia) around 5,000–4,500 cal bp. Subsequently around 4,000–3,500 cal bp evergreen oak-olive forests expanded massively when fire activity declined and lake productivity and anoxia reached Holocene maxima. Land-use activities during the past 4,000 years (since the Bronze Age) gradually disrupted coastal forests, but relict stands persisted under rather stable environmental conditions until ca. 200 cal bp, when agricultural activities intensified and Pinus and Eucalyptus were planted to stabilize the sand dunes. Pervasive prehistoric land-use activities since at least the Bronze Age Nuraghi period included the cultivation of Prunus, Olea europaea and Juglans regia after 3,500–3,300 cal bp, and Quercus suber after 2,500 cal bp. We conclude that restoring less flammable native Q. ilex and O. europaea forest communities would markedly reduce fire risk and erodibility compared to recent forest plantations with flammable non-native trees (e.g. Pinus, Eucalyptus) and xerophytic shrubland (e.g. Cistus, Erica).
Micro-perforated panels for noise reduction

Published: April 2021

AbstractSpace limitations in duct applications, new industrial and health safety regulations require new absorber configurations. Micro-perforated panels (MPP) as used in micro-perforated absorbers (MPA) allow new sound absorber concepts in the category of metamaterials. In this contribution we investigate MPA designs for the low and mid-to-high frequency range and apply finite element (FE) simulations to precisely design absorber configurations for applications in room acoustics and axial fans. The investigations show that the MPA’s cavity configuration must be customized for the desired frequency range and has significant influence on fan performance when applied in a duct flow setup.

Abstract
Introduction
Reverse shoulder arthroplasty (RSA) leads to medialization and distalization of the centre of rotation of the shoulder joint resulting in lengthening of the deltoid muscle. Shear wave ultrasound elastography (SWE) is a reliable method for quantifying tissue stiffness. The purpose of this study was to analyse if deltoid muscle tension after RSA correlates with the patients’ pain level. We hypothesized that higher deltoid muscle tension would be associated with increased pain.

Material and methods
Eighteen patients treated with RSA were included. Constant score (CS) and pain level on the visual analogue scale (VAS) were analysed and SWE was performed on both shoulders. All three regions of the deltoid muscle were examined in resting position and under standardized isometric loading.

Results
Average patient age was 76 (range 64–84) years and average follow-up was 15 months (range 4–48). The average CS was 66 points (range 35–89) and the average pain level on the VAS was 1.8 (range 0.5–4.7). SWE revealed statistically significant higher muscle tension in the anterior and middle deltoid muscle region in patients after RSA compared to the contralateral non-operated side. There was a statistically significant correlation between pain level and anterior deltoid muscle tension.

Conclusion
SWE revealed increased tension in the anterior and middle portion of the deltoid muscle after RSA in a clinical setting. Increased tension of the anterior deltoid muscle portion significantly correlated with an increased pain level. SWE is a powerful, cost-effective, quick, dynamic, non-invasive, and radiation-free imaging technique to evaluate tissue elasticity in the shoulder with a wide range of applications.

Zusammenfassung
Zielsetzung
Die Einführung des Wiederbelebungsunterrichts an Schulen soll die Reanimationsbereitschaft in der Gesellschaft und das Überleben von Menschen mit einem außerklinischen Herz-Kreislauf-Stillstand nachhaltig verbessern. Ziel der vorliegenden Untersuchung war es zu prüfen, wie Lehrkräfte als qualifizierte Multiplikatoren den Wiederbelebungsunterricht in ihren Schulen eigenständig durchführen.

Methodik
Die Uniklinik Köln qualifizierte in Kooperation mit dem Deutschen Rat für Wiederbelebung e. V. in einem speziell entwickelten Kurs Lehrkräfte von weiterführenden Schulen. Von Juli bis November 2019 erfolgte die Evaluation dieses Lehrermultiplikationskonzepts mittels einer webbasierten Umfrage.

Ergebnisse
An der Befragung nahmen 23 von 26 Schulen teil (88 %). Insgesamt haben 96 % (n = 22) der an der Befragung teilnehmenden Schulen den Wiederbelebungsunterricht eingeführt. Es wurden 229 Lehrkräfte ausgebildet, die in dem 2‑jährigen Beobachtungszeitraum 8612 Schüler trainierten. Im Mittel trainierte eine qualifizierte Lehrkraft in ihrer Schule 38 Schüler in Wiederbelebung. Die Multiplikationsfaktoren (Anzahl der trainierten Schülerinnen und Schüler pro Lehrkraft) waren schulindividuell unterschiedlich (Minimum/Maximum: 10/1747). Die schulintern projektverantwortlichen Lehrkräfte gaben an, sich sehr sicher in der eigenständigen Durchführung des Wiederbelebungsunterrichts zu fühlen.

Zusammenfassung
Speziell qualifizierte Lehrkräfte führen den Wiederbelebungsunterricht an ihren Schulen zuverlässig ein. Um noch mehr Schüler mit dem Wiederbelebungstraining zu erreichen, müssen die Multiplikationsfaktoren durch gezielte Unterstützungsangebote weiter erhöht werden.
Olfactory responses of Argentine stem weevil to herbivory and endophyte-colonisation in perennial ryegrass

Published: April 2021

AbstractArgentine stem weevil adults (ASW,Listronotus bonariensis) feed on the leaves of agricultural grasses and their larvae mine the pseudostem, causing extensive damage that can result in plant death. Plants emit volatiles that serve as signals to host-searching insects and these odours can be altered by both herbivory and fungal endophyte-infection. This study investigated whether ASW adults utilise olfaction to identify their host plants, perennial ryegrass (Lolium perenne), and if conspecific herbivory or the presence ofEpichloë festucaevar.loliifungal endophytes (strain wild-type or AR1) influenced such responses. Results from olfactometer bioassays established that ASW adults were able to utilise their olfactory response to orient towards volatiles released by perennial ryegrass and further, the weevils displayed a preference for plants previously damaged by conspecific weevils. However, there was no evidence that weevils had the ability to distinguish between endophyte-infected and endophyte-free plants using olfaction alone. Using a push–pull extraction technique, thirteen volatile compounds were identified in the blend released by perennial ryegrass. Endophyte and herbivory were found to alter these volatile compounds and quantities emitted by this forage grass. This study suggests that despite observing differences in the plant volatile blend, ASW do not perceive endophyte (wild-type and AR1) using olfaction alone and must rely on other cues, e.g. contact chemoreception or post-ingestional malaise, to detect the presence of a bioactive endophyte in an otherwise acceptable host plant.

AbstractThe spread of alien species with the expansion of road networks and increasing traffic is a well-known phenomenon globally. Besides their corridor effects, road maintenance practices, such as the use of de-icing salts during winter facilitate the spread of halophyte (salt tolerant) species along roads. A good example isPlantago coronopus, a mainly coastal halophyte which has started spreading inland from the Atlantic and Mediterranean coastal habitats, recently reaching even Central European countries (e.g. Hungary). Here we studied the spread of this halophyte and tried to identify factors explaining its successful dispersion along roads, while also comparing native and non-native roadside occurrences with regard to altitude of the localities, size of roadside populations and frequency of roadside occurrences. We completed a comprehensive literature review and collected more than 200 reports of occurrence from roadsides spanning a total of 38 years. During systematic sampling the frequency of the species along roads was significantly higher in the Mediterranean (native area), than along Hungarian (non-native area) roads, however the average number of individuals at the sampling localities were very similar, and no significant difference could be detected. Using a germination experiment, we demonstrate that although the species is able to germinate even at high salt concentrations, salt is not required for germination. Indeed salt significantly decreases germination probability of the seeds. The successful spread of the species could most likely be explained by its remarkably high seed production, or some special characteristics (e.g. seed dimorphism) and its ability to adapt to a wide range of environmental conditions. Considering the recent and rapid eastward spread ofP. coronopus, occurrences in other countries where it has not been reported yet can be predicted in coming years.
Genetic programming for feature model synthesis: a replication study
Authors: Vescan Andreea , Pintea Adrian , Linsbauer Lukas , Egyed Alexander 
Published: April 2021

AbstractSoftware Product Lines (SPLs) make it possible to configure a single system based on features in order to create many different variants and cater to a wide range of customers with varying requirements. This configuration space is often modeled using Feature Models (FMs). However, in practice, the SPL (and consequently the FM) is often created after a set of variants has already been created manually. Automating the task of reverse engineering a feature model that describes a set of variants makes the process of adopting an SPL easier. The genetic programming pipeline is a good fit for feature models and has been shown to produce good reverse engineering results. In this paper, we replicate the results of such an existing approach with a larger set of feature models and investigate the effects of various genetic programming parameters and operators on the results. The design of our replication experiments employs three perspectives: duplicate the exact conditions using various features models, study the interaction of two parameters of the genetic programming approach, and optimize the values for the population and generation parameters and for the mutation and crossover operators. Results reinforce the previously obtained outcome, the original study being confirmed. The relations between the number of features and number of generations, respectively number of features and size of populations were also investigated and best values based on obtained results are provided. The current study also aimed to optimize various parameters of the genetic programming approach, the interpretation of those experiments discovering concrete values.
