Warum wollen Eltern (nicht) an Elternbildung teilnehmen? Analysen der Rolle von Bildungsniveau und Migrationshintergrund für die elterliche Motivation zur Teilnahme an Elternbildung
Authors: Fischer Franzisca P. , Gorges Julia 
Published: March 2023

ZusammenfassungDie Inanspruchnahme von Elternbildung kann Eltern in der Bewältigung ihres Erziehungsalltags unterstützen, ist jedoch durch ein Präventionsdilemma gekennzeichnet. Bislang liegen nur wenige theoriegeleitete Studien zur Teilnahmemotivation von Eltern an Elternbildung vor. Die vorliegende Untersuchung adressiert vor dem Hintergrund der Erwartungs-Wert-Theorie die Struktur des subjektiven Wertes von Eltern unterschiedlichen sozialen Hintergrunds (N = 921; 87 % weiblich) sowie die Beiträge der Wertkomponenten zur Vorhersage der elterlichen Teilnahmemotivation an einem bevorstehenden Elternbildungsangebot zum Thema Eltern-Schule-Kooperation. Konfirmatorische Faktorenanalysen zeigen eine 3‑Komponenten-Struktur des subjektiven Wertes mit zwei motivationsförderlichen Wertkomponenten – bezogen auf den Inhalt und den Status als Teilnehmer*in – und einer motivationsabträglichen Kostenkomponente. Die Items der motivationsförderlichen Wertkomponenten decken intrinsische, persönliche und utilitaristische Aspekte ab. Die Kostenkomponente umfasst die für die Teilnahme erforderliche Anstrengung, monetäre, zeitliche sowie psychologische Aspekte. Die Wertkomponenten sagen einen Bilanzwert als Indikator der resultierenden Teilnahmemotivation erwartungsgemäß positiv bzw. negativ vorher. Bei insgesamt mittleren Effektstärken weisen der inhalts- und statusbezogene Wert und die Kosten eine annähernd gleich hohe Vorhersagekraft auf. Mit Blick auf das elterliche Bildungsniveau und einen Migrationshintergrund zeigen die Wertkomponenten (partielle) metrische Messinvarianz. Eltern mit niedrigem (vs. hohem) Bildungsniveau gewichten die Kostenkomponente geringer, während sich beim Migrationshintergrund keine signifikanten Gruppenunterschiede zeigen. Die Befunde deuten darauf hin, dass Angebote für Eltern möglichst niedrigschwellig gestaltet sein sollten. Weiterhin scheint Eltern der Inhalt der Angebote sowie ein Zusammentreffen mit anderen Eltern wichtig zu sein. Hierbei lohnt sich ein differenzierter Blick auf die Zielgruppe der jeweiligen Angebote. Die Befunde tragen zur theoriegeleiteten Erforschung elterlicher Teilnahmemotivation an Elternbildung bei.
Phase-Field Study of the History-Effect of Remelted Microstructures on Nucleation During Additive Manufacturing of Ni-Based Superalloys

Abstract
In the current work we employ multi-phase-field simulations to understand the effect of remelting on microstructure evolution, especially on nucleation of new grains during selective electron beam melting (SEBM) of Ni-based super alloy. The phase-field model is coupled to both mass and heat transport phenomena including release of latent heat of solidification. We run remelting simulations in both as cast and homogenized conditions. Experimental observations show that remelting triggers the nucleation of new grains at the melt pool border. The simulation results shed more light on the local conditions at the melt pool border thereby enhancing our understanding of the mechanisms responsible for the nucleation. The simulation results are validated with experimental results obtained for the Ni–20.5 mol pct Al model binary alloy.
Definition and evaluation of good manufacturing practices for plastic injection molding
Authors: Mena Ledezma Jhorman , Posada Correa Juan Carlos 
Published: March 2023

AbstractIn this work, the impact of good manufacturing practices (GMP) on the specific energy consumption (SEC) of plastic injection molding process, in 9 representative companies in Colombia, was studied. The GMP applied to the injection molding process and the degree to which they are adopted by the companies were defined. Afterwards, the SEC of 17 representative injection molding processes in those companies were evaluated. Finally, the impact of applying the GMP and their effect on SEC were studied. The degree of application of GMP on the analyzed companies ranges from 35 to 72%. A single SEC value could not be established for all the injection systems, because it depends on the injected weight and the productivity of each mold-machine-material combination. Nevertheless, a characteristic curve was defined for different systems. A relationship between the application of GMP and SEC was found. It was observed that all GMP contributed to improve the SEC, with different significance, ranging the relevance from 6 to 14%. Finally, it was concluded, taking in consideration a representative company, that “Plasticizing” and “Drive Units” were the most relevant categories to impact the SEC.
I Don’t Care Who You Are: Adult Respondent Selection Does Not Alter Child Deprivation Estimates

Published: March 2023

AbstractThe last decade has seen strong developments in child poverty measurement. Children are largely recognised to have age-specific needs, which has led to the development of child-specific poverty measures. One of the current ongoing debates is how best to collect that information. Questions regarding child deprivation are most often answered by a reference adult and assume that adult respondents provide accurate reports about their children’s needs. These assumptions have largely gone untested. Making use of a unique feature of the Fijian Household Income and Expenditure Survey (2019/20), this paper explores the effect of respondent selection on child deprivation estimates. We compare three approaches to the selection of adult respondents commonly used in survey design: the children’s mother, the household head, and a random adult respondent in the household. We find that adults largely agree on whether children are deprived of specific items. However, in between 5 to 24% of households (depending on the indicator), adults provide different responses regarding whether children have specific items. Despite these differences, respondent selection does not substantially alter child multiple deprivation estimates or the socio-demographic characteristics of the deprived child population. The article will be of interest to those designing surveys or questionnaires to measure child poverty and children’s unmet needs.

Published: March 2023

ZusammenfassungEine wesentliche Zielgröße organisationaler Dopingprävention ist es, Athlet:innen zu reflektierten Entscheidungen zu befähigen, sodass Doping im Leistungssport unwahrscheinlicher wird. Hierfür bedarf es im Sinne der Partizipation, entgegen einer einfachen Informationsbereitstellung oder Verweise auf Regularien, einer aktiven Einbindung und Beteiligung auf Basis einer bedarfs- und vor allem bedürfnisgerechten Ausrichtung der Dopingprävention. Eine nachhaltige Identifikation mit einem sauberen Sport kann dann gelingen, wenn Athlet:innen nicht nur im Rahmen von Präventionsangeboten sozial eingebunden sind, sondern indem Kompetenzen erlebt und hierüber Möglichkeiten der Autonomieförderung bzw. der Selbstbestimmung gegeben werden. Der vorliegende Beitrag stellt einen Auszug aus dem Forschungsprojekt Partizipation von Athlet:innen in der Dopingprävention dar und beschäftigt sich damit, inwieweit eine Beteiligung von Athlet:innen in der Dopingprävention im internationalen Vergleich stattfindet. Weiterhin werden daraus ableitend und basierend auf einem partizipatorischen Forschungsansatz systematische Handlungsempfehlungen für die Nationale Anti-Doping-Agentur Deutschland (NADA) präsentiert, die im Forschungsprozess mit Entscheidern der Nationalen Doping-Agenturen (NADOs), des Bundesinstituts für Sportwissenschaft (BISp) sowie den betroffenen Athlet:innen und deren Sprecher:innen entwickelt wurden.

Published: March 2023

AbstractThe mapping and assessment of ecosystems and their services (MAES) is key to inform sustainable policy and decision-making at national and sub-national levels. Responding to the paucity of research in sub-Saharan Africa, we conduct a pilot study for Eritrea that aims to map and assess the temporal dynamics of key ecosystems and their services. We reviewed policy and legal documents, analyzed land cover changes and estimated the potential for ecosystem services supply through an expert-based matrix approach. Our results showed that from 2015 to 2019, the potential supply of the ecosystem services analyzed (e.g., crop provisioning, water supply and recreation) increased, with the exception of wood supply. Overall, our study presents policy-relevant insights as to where to conserve, develop, or restore ecosystem services supply in Eritrea. Our approach is transferable to similar data scarce contexts and can thereby support policies toward more sustainable land development for people and nature.

Abstract
Purpose
Overweight and obesity have increased in people living with HIV (PLH). Our study evaluated weight, body-mass-index (BMI), and waist-to-hip ratio (WHR) change over 5 years of follow-up in PLH compared to the general population.

Methods
HIV-positive participants in the HIV Heart Aging (HIVH) study were matched 1:2 by age and sex with HIV-negative controls of the population-based Heinz Nixdorf Recall (HNR) study. Both studies were recruited in the German Ruhr area. The association between HIV and weight, BMI, and WHR changes was examined using linear regression. Regression models were adjusted for parameters potentially affecting weight gain.

Results
The matched HIVH and HNR participants (N = 585 and N = 1170, respectively; 14.7% females) had a mean age of 55 years at baseline. Despite the lower baseline weight (− 6 kg, 95% CI − 7.46 to − 4.59), the linear regression showed greater absolute and relative weight and BMI increases after 5 years in HIVH compared to HNR. Adjusting the linear regression models for smoking amplified that HIVH had a higher absolute and relative weight difference of 0.7 kg or ~ 1% compared to HNR after 5 years (95% Cl 0.1 to 1.3 and 0.2 to 1.6, respectively). Adjusting for HDL, LDL, systolic blood pressure, and diabetes mellitus did not affect the results.

Conclusions
PLH had lower weight than the general population at baseline and after 5 years, but experienced greater increases in body weight after 5 years. WHR change after 5 years was lower in PLH compared to the general population, despite a higher WHR at baseline.
Looking at China from Abroad: intermediality as a tool for documentary
Authors: Mello Cecília 
Published: March 2023

AbstractIn 2020, due to the Coronavirus Pandemic, travel to China and around the world was mostly suspended. In the face of such restrictions, the ‘Looking China Youth Film Project’ took a different approach by inviting students from around the world to make documentary short films in remote mode. This meant employing different expressive resources and a mixed-media format, including techniques such as animation, graphics, typography, photographs, and paintings. The aim of this article is to shed light on this pioneering initiative from the point of view of the relationship between intermediality and forms and functions of the documentary genre. It opens with a discussion around the question of intermediality in the audiovisual media, considering how a realist impulse coexists in the cinema with its mixed-media nature, thus bringing together Bazin’s ontology of the photographic image and his case for cinema as an impure form of art. This is followed by a discussion about the recent field of the ‘animated documentary’, both as a practice and as a theoretical debate, which faces the apparent incongruity between film’s unique ability to record reality – which gave rise to the documentary genre, and animation’s creation of a world without any referent in reality. Finally, it considers the experience of the Looking China Youth Film Programme in 2020, with a special emphasis on six documentary films made from a mixture of live images, animation sequences, graphics and screens. The examples analysed allow me to delve into different aspects of the research on cinema and intermediality, including the animated documentary, the influence of the internet in audiovisual media, and the possibilities of a remote practice of film production.
Forced-response characterization of PBF-LB/AlSi10Mg particle dampers with thin and flat cavities
Authors: Westbeld Julius , von Coburg Fabio , Höfer Philipp 
Published: March 2023

AbstractPowder Bed Fusion (PBF) enables the production of complex geometries which offer the opportunity to manufacture lightweight, stiffness-optimised or integrally designed components. Although these properties are usually advantageous for the performance in many applications, they pose disadvantages under vibration as they lead to low damped components. These are prone to high vibration amplitudes which result in higher sound radiation and a reduced lifetime. Particle damping can counteract these disadvantages. By including cavities during the design process, unmelted powder remains inside the component after its production. This powder dissipates energy under vibration by inelastic impacts and friction in particle-particle or particle-wall-interactions, increasing the damping characteristics of the component. In this work, additively manufactured AlSi10Mg specimens with cavities are investigated with respect to their damping characteristics by experimental modal analysis. The focus of the investigation is on thin and flat cavities that can be easily integrated into components without adapting the external geometry. The damping characteristics in dependence on excitation amplitude and mode are quantified. The extent to which settling effects of the powder during shaking influence the damping is analysed. The vibration of the specimens is forced by an electrodynamic shaker and their response is measured contactlessly via Scanning Laser Doppler Vibrometry (SLDV). A damping effect of up to 564% depending on the mode, excitation amplitude and specimen can be achieved. In addition, a significant settling effect of the powder which hampers the damping effect is identified by CT scans and modal analysis.
Einfluss der Stoßwelle auf die Schutzwirkung eines Kapselgehörschützers beim Schuss mit einer Jagdwaffe
Authors: Kluth Karsten , Jung Pascal , Wurm Dennis , Schmitz Ingo , Sänger Nicolas 
Published: March 2023

ZusammenfassungZur Überprüfung des Einflusses der Stoßwelle auf den Kapselgehörschutz beim Schuss wurden 73 Jäger befragt, 20 Jäger audiometriert und einzelne Schießversuche mit einer Großkaliberbüchse durchgeführt. Um einen menschlichen Einfluss auf die Messwerte beim Schießen auszuschließen, wurde der verwendete Kapselgehörschützer einem Kunstkopf aufgesetzt. Die Auswertung von Umfrage und Audiometrie ergab, dass die Gehörgefährdung durch den Schussknall weitgehend bekannt ist. Dennoch zeigten sich teilweise dramatische Hörverluste im Audiogramm bei 6000 Hz und eine Differenzierung der Hörminderung zwischen dem der Waffe zugewandten und abgewandten Ohr. Für die Auswertung der durch die Stoßwelle ausgelösten Abhebebewegung des Kapselgehörschützers vom Kunstkopf beim Schuss wurde eine Hochgeschwindigkeitskamera eingesetzt. Die Einflüsse von Mündungsbremse und Schalldämpfer auf die Messergebnisse wurden ebenfalls analysiert. Die Bilder dokumentieren, dass es beim abgewandten Ohr zu einer Abhebung der Kapsel beim Schuss sowohl bei blankem Rohr als auch mit aufgesetzter Mündungsbremse kommt, wohingegen bei einem aufgesetzten Schalldämpfer zwar eine geringe Bewegung der Kapsel zu beobachten ist, aber nicht die dämmwirkungsmindernde Spaltbildung zwischen Kapsel und Kunstkopf ausgelöst wird.Praktische Relevanz: Impulsschallbelastungen mit sehr hohen Spitzenschalldruckpegeln üben eine starke Gehörgefährdung aus. Kapselgehörschützer versprechen eine ausreichende Schutzwirkung, die aber beim Schuss nur bedingt messtechnisch ermittelt werden konnte. Die Empfehlung geht zum kombinierten Gehörschutz oder zum zusätzlich verwendeten Schalldämpfer.

Published: March 2023

AbstractA novel microvibration hammerhead consists of a piezoelectric actuator and a double cross-shape compliant mechanism (DCCM) is presented in this paper. The output force of the piezoelectric actuator can be detected in real time by an inside-installed pressure sensor. A theoretical model including the stiffness, first natural frequency, and stress of the DCCM and the displacement output of the piezoelectric actuator are established, and then they are further analyzed using the finite element analysis method. The effects of the beam thickness on the static and dynamic properties are deeply analyzed and compared. A prototype micro hammering system is constructed by integrating the microvibration hammerhead assembly and controlling system. Various experiments are also carried out to verify the basic performance of the micro hammering system.
Bystanders’ Responses to Witnessing Cyberbullying: the Role of Empathic Distress, Empathic Anger, and Compassion

Abstract
A lack of empathy for victimized individuals has been cited as a reason for why bystanders fail to intervene when they witness bullying. However, limited research has addressed how different empathic and compassionate responses could account for diverse bystander behaviors. In this study, we investigated the unique associations of empathic distress, empathic anger, and compassion with different ways that bystanders intend to respond to witnessing cyberbullying, including passive bystanding, aggressive defending, and prosocial defending. Participants were 270 Australian university students from diverse racial backgrounds (M
age = 20.34, SD = 2.78, age range 18 to 29 years, 74.8% females). Participants completed an online survey. As predicted, after controlling for gender, cybervictimization, cyberbullying, and social desirability, a multivariate path model revealed that empathic distress, empathic anger, and compassion had different associations with the three bystander behavioral intentions. Students higher in empathic distress and lower in empathic anger reported greater passive bystander intentions in response to witnessing cyberbullying, with those higher in empathic anger intending to use more aggressive and prosocial defending. Compassion was associated with lower aggressive defending intentions and higher prosocial defending intentions, making it unique in differentiating these two forms of defending. These findings emphasize the differential role of empathic distress, empathic anger, and compassion in predicting cyberbullying bystander behavioral intentions. Future research is needed to investigate how empathic anger and compassion can be targeted in interventions to help witnesses productively intervene to stop cyberbullying and support victimized individuals.

Published: March 2023

AbstractWith environment becoming deteriorated, packaging industry is expected to take the circular economy (CE) approach through packaging design which is estimated to effect up to 80% of environmental sustainability impacts. This research aims to investigate the practical design guidance and considerations throughout the design process for developing CE-oriented packaging design solutions. Qualitative methods including interviews, workshops and secondary data were adopted to explore the circular packaging design practices which have been proven effective from 9 internationally leading firms. A ‘Design for Circular Packaging (DfCP)’ framework for packaging industry has been developed to guide firms and designers to create effective circular packaging design solutions. Major considerations in the CE packaging concepts, material selection, design process and manufacture are also addressed.
Covid-19: did higher trust societies fare better?
Authors: Casey Bernard H 
Published: March 2023

AbstractSocial trust—between governments and people and between individuals—and trust in science were proposed as prerequisites for tackling covid. Others suggested less democratic societies were more able to impose strict rules stopping the virus. These propositions were tested for a group of mainly advanced countries.The dependent variable is cumulated deaths from covid. Findings are broken down between (a) OECD member countries, (b) these and countries having cooperation agreements with it, and (c) all these plus China. They are also broken down by time—between (a) the period before the appearance of “new variants” in late 2020 and (b) the period from then until end September 2021.The best, most parsimonious, models explain nearly half of the changes in the level of deaths. Trust in government improves outcomes, as does interpersonal trust. Vaccine antipathy does not play a role. Also, there is little indication that authoritarian regimes performed better than higher trust societies. In the first period, increasing wealth inequality—indicating a more divided society—is related to higher death rates. Hospital bed availability is important then, but not thereafter. Furthermore, as the pandemic persisted, the importance of pre-existing levels of social trust declined.The paper warns that institutions and cultures cannot easily be transferred from one country to another. Nor would all transfers be desired. It also suggests that some other lessons of what contributed to better outcomes under covid might be relevant for the monkeypox virus—its successor public health emergency.
