Alone in a Crowd: Is Social Contact Associated with Less Psychological Pain of Loneliness in Everyday Life?
Authors: Stavrova Olga , Ren Dongning 
Published: May 2023

AbstractPeople are often advised to engage in social contact to cope with the experience of loneliness and improve well-being. But are the moments of loneliness actually more bearable when spent in other people’s company? In this research, we proposed and tested two conflicting theoretical accounts regarding the role of social contact: social contact is associated with a stronger (the amplifying account) or with a weaker (the buffering account) negative effect of loneliness on psychological well-being. Analyses of three datasets collected using ecological momentary assessments (Nindividuals = 3,035) revealed that the negative association between loneliness and well-being was stronger when participants were with others than alone, consistent with the amplifying account. Further, when participants experienced high levels of loneliness, being with others was associated with the same or with even a lower level of well-being than being alone. These findings suggest that simply spending time with others (vs. alone) is not associated with a reduced burden of loneliness and may even backfire.
A fast water-slide layout approach using smooth surfaces, Saint Venant’s stationary water streamline, and passenger sliding interaction – theory, implementation, and validation
Authors: Stepken Alina , Kecskeméthy Andrés , Geu Flores Francisco 
Published: May 2023

AbstractWater-slide manufacturers are constantly searching for innovative designs that maximize the rider’s fun while complying with safety requirements. However, the current state-of-the-art does not offer any simulation tool capable of aiding the design phase before manufacture in an affordable computational time. In this paper, we present a novel approach using smooth surface models together with Saint Venant’s filament theory to predict the water channel and, by this, a realistic estimation of passenger/water-slide interaction. The paper covers the theory and the experimental validation for the case of circular slide cross-sections. It is shown that the predicted water channel follows very well the measurement even without the influence of Saint Venant’s water-height terms and of the elliptical correction of the water cross-section for slanted water streamlines with respect to the centerline of the circular tube. Thus, for this kind of applications, a simple Bernoulli streamline model with proper water-slide friction parameters is shown to be sufficient. On the other hand, parameter identification of fluid-surface friction shows that three terms must be considered: a static one, a curvature-dependent correction, and a third correction factor for changes from low to large curvature (splashing effect). The results are also compared with fluid simulations using OpenFOAM. It is shown that the results of the simple model are not less accurate than the fluid-dynamics model, while needing only 1/100.000 of the computational time. The paper shows also the passenger/slide interaction by a multibody model including contact and passenger/fluid interactions. It is shown that the interaction between the passenger and water is significant for correct reproduction of real motion, showing that the water channel is relevant for computer-based water-slide layouts. As the water-channel parameters can be sufficiently modeled by Bernoulli’s streamline theory, the approach is independent of the slide cross-section and thus extendable to general cases. Also, as the computations run at 7/10 of real time, they can be used for online optimizations and passenger-specific actions on site.
Revisiting policy combinations under IS–LM–EE framework introducing capacity utilization

Published: May 2023

AbstractThe study introduces the capacity utilization factor into the existing works on the effect of technological progress towards environment friendly capital formation to analyse the impacts of fiscal and monetary policies in an IS–LM framework and concludes that the effects of fiscal and monetary policies on conservation capital and permit cost in the presence of technological progress cause increases in output, but these increases will centre around the full capacity utilization level. Further, the empirical exercise in a pooled regression model involving the income-influencing factors through fiscal and monetary policies shows that technological progress endowed with emission intensity and capacity utilization dummy for the world’s 28 countries, confirms the theoretical results in most circumstances. The study signifies the role of institutions and technological progress as the backbone to frame fiscal and monetary policies as an effective instrument for getting green growth.
Making, unmaking and remaking of context in entrepreneurial identity construction and experiences: a comparative analysis between Türkiye and the Netherlands
Authors: Ozasir Kacar Sibel 
Published: May 2023

AbstractThis study analyses how women entrepreneurs of Turkish origin do context in constructing their entrepreneurial identities and experiencing their entrepreneurship in two national contexts, namely Türkiye and the Netherlands. In order to study context, we use the term opportunity structures and analyse how these entrepreneurs interpret and perceive opportunity structures, and construct their entrepreneurial identities in relation to their interpretations. Relying on the life story narratives of 21 women entrepreneurs, we analyse social, political and institutional opportunity structures and the relationship between these and the processes of entrepreneurial experiences and identity construction. We propose that Turkish women entrepreneurs make, unmake and remake context during these processes. In the Netherlands, these entrepreneurs challenge existing opportunity structures either by providing alternative images of a Turkish migrant woman or questioning culturalist perspectives behind these opportunity structures. In Türkiye, they are compelled to be more hesitant in challenging the opportunity structures. They either have to step down from their enterprises or downgrade their entrepreneurial affiliations to fulfil the requirements of opportunity structures. This study contributes to the field of entrepreneurship in its contextualisation by providing an extended understanding of the ways in which entrepreneurs do context.
Exploring the Effects of Volunteering on the Social, Mental, and Physical Health and Well-being of Volunteers: An Umbrella Review
Authors: Nichol Beth , Wilson Rob , Rodrigues Angela , Haighton Catherine 
Published: May 2023

AbstractVolunteering provides unique benefits to organisations, recipients, and potentially the volunteers themselves. This umbrella review examined the benefits of volunteering and their potential moderators. Eleven databases were searched for systematic reviews on the social, mental, physical, or general health benefits of volunteering, published up to July 2022. AMSTAR 2 was used to assess quality and overlap of included primary studies was calculated. Twenty-eight reviews were included; participants were mainly older adults based in the USA. Although overlap between reviews was low, quality was generally poor. Benefits were found in all three domains, with reduced mortality and increased functioning exerting the largest effects. Older age, reflection, religious volunteering, and altruistic motivations increased benefits most consistently. Referral of social prescribing clients to volunteering is recommended. Limitations include the need to align results to research conducted after the COVID-19 pandemic. (PROSPERO registration number: CRD42022349703).

AbstractZinc oxide nanoparticles (ZnO-NPs) have in recent times shown effective adsorption capability for the confiscation of colour contaminants from aqueous environments (aquatic ecosystems or water bodies) due to the fact that ZnO contains more functional groups. Direct blue 106 (DB106) dye was selected for this present study as a model composite due to its wide range of uses in textiles (cotton and wools), woods, and paper industries, as well as their therapeutic applications, along with its potential for impairments. This study therefore focuses on the use of DB106 dye as a model composite due to its wide range of uses in textiles (cotton and wools), woods, and paper industries, as well as their therapeutic applications and their potential for impairments. Furthermore, the surface functionalization, shape, and composite pore size were revealed by TEM, FTIR, UV, and BET techniques. The current study uses green synthesis method to prepare ZnO-NPs as an adsorbent for the DB106 dye molecules adsorption under various conditions using the batch adsorption process. The adsorption of DB106 dye to the ZnO-NPs biosorbent was detected to be pH-dependent, with optimal adsorption of DB106 (anionic) dye particles observed at pH 7. DB106 dye adsorption to the synthesized ZnO-NPs adsorbent was distinct by means of the linearized Langmuir (LNR) and pseudo-second-order (SO) models, with an estimated maximum adsorption capacity (Qm) of 370.37 mg/g.

Abstract
Purpose
Long-term agricultural irrigation with untreated wastewater has resulted in metals and metalloids accumulation in soil. Little information is available on the consequences of a change to irrigation with treated water on the mobility of these potentially toxic elements (PTEs).

Materials and methods
The potential mobility of PTEs was assessed using sequential extractions performed on soil irrigated with untreated wastewater for a century in Mexico. The possible effects of change in irrigation practices on PTEs mobility was evaluated through batch experiments, simulating a decrease in pH, an increase in salinity, and in chlorine of the irrigation water. Geochemical modeling allowed predicting the speciation of mobilized PTEs.

Results and discussion
Soils irrigated with untreated water were mainly enriched with PTEs in surface horizons. Only Cd and As were found in the soluble or exchangeable fractions (< 20%). Cu and Pb were mainly associated with soil organic matter (OM), whereas As and Zn were bound to iron oxides, and Cr with refractory minerals. Batch experiments revealed that acidification resulted in the increased solubility of Cu, Zn, and Cd for surface samples, and As in deep horizons. In contrast, increased salinity only mobilized Zn, Cd, and Cr. Water chlorination mobilized higher amount of Zn, Pb, and Cd compared to the other experiments. As was not mobilized for these two experiments.

Conclusion
A change in irrigation practices could increase the mobility of PTEs if water treatment is not adapted to the soil type. The mobilization of PTEs, especially As and Cd, could affect both crops and groundwater quality. It is essential to monitor this mobility to avoid future risks to human health.
How do teachers engaging messages affect students? A sentiment analysis
Authors: Falcon Samuel , Leon Jaime 
Published: May 2023

AbstractGathering information from students’ answers to open-ended questions helps to assess the quality of teachers’ practices and its relations with students’ motivation. The present study aimed to use sentiment analysis, an artificial intelligence-based tool, to examine students’ responses to open-ended questions about their teacher’s communication. Using the obtained sentiment scores, we studied the effect of teachers engaging messages on students’ sentiment. Subsequently, we analysed the mediating role of this sentiment on the relation between teachers’ messages and students’ motivation to learn. Results showed that the higher the students’ perceived use of engaging messages, the more positive their sentiments towards their teacher’s communication. This is an important issue for future research as it shows the usefulness of sentiment analysis for studying teachers’ verbal behaviours. Findings also showed that sentiment partially mediates the effect of teachers engaging messages on students’ motivation to learn. This research paves the way for using sentiment analysis to better study the relations of teachers’ behaviours, students’ sentiments and opinions, and their outcomes.

Authors: Schölmerich Franziska , Koch Jan , Schermuly Carsten C. 
Published: May 2023

ZusammenfassungViele verschiedene Maßnahmen und Praktiken werden in Unternehmen mit New Work assoziiert. Um an dieser Stelle die Übersichtlichkeit zu verbessern, entwickeln wir eine Taxonomie, in der New Work-Praktiken (NWP) mit Blick auf ihre Wirkungsebene (Organisation vs. Person) und ihr Wirkungsziel (Effizienz vs. Innovation) durch Expert:innen (N = 23) eingeordnet werden. Wir nutzen zudem den angepassten Datensatz des aktuellen New Work-Barometers (N = 530), um Zusammenhänge zwischen der Lokalisierung und der Einsatzhäufigkeit von NWP zu analysieren. Die Ergebnisse zeigen, dass personenbezogene NWP nicht häufiger eingesetzt werden und Unternehmen vor allem NWP einsetzen, die auf Effizienz statt auf Innovation abzielen.

AbstractDoubled haploid (DH) plants have been widely used for breeding and biological research in crops. Populus spp. have been used as model woody plant species for biological research. However, the induction of DH poplar plants is onerous, and limited biological or breeding work has been carried out on DH individuals or populations. In this study, we provide an effective protocol for poplar haploid induction based on an anther culture method. A total of 96 whole DH plant lines were obtained using an F1 hybrid of Populus simonii × P. nigra as a donor tree. The phenotypes of the DH population showed exceptionally high variance when compared to those of half-sib progeny of the donor tree. Each DH line displayed distinct features compared to those of the other DH lines or the donor tree. Additionally, some excellent homozygous lines have the potential to be model plants in genetic and breeding studies.

Published: May 2023

AbstractAccording to the European energy consumption reports, the highest energy/fuel consumption in the residential sector is due to space heating, followed by water heating. Generally, the product used to warm water in residential buildings is a boiler system where a heat exchanger is the core of the system. The paper provides a Life Cycle Assessment analysis of a traditional heat exchanger used in domestic boilers with the aim to identify critical aspects and environmental hotspots for the development of a novel concept of the heat exchanger. The methodology used to collect eco-design guidelines from the Life Cycle Assessment analysis is proposed within the paper. Several eco-design actions were put into practice to reduce the environmental issues in each phase of the life cycle from the materials used, the manufacturing processes as well as the product geometry to increase energy efficiency during the use. Concerning the materials and manufacturing phase, a novel design based on a different material (e.g., stainless steel) was developed to replace a mix of materials (i.e., copper and aluminum alloy). Concerning the use phase, the overall product efficiency was increased allowing important savings in terms of gas/energy consumption, by the adoption of a novel design (e.g., spiral pipe). The new heat exchanger design shows better environmental performance in each Life Cycle Assessment indicator, saving more than 40% in CO2 emissions (Global Warming Potential) in the whole product life cycle.
Shall We Establish Sexual Consent or Would You Feel Weird? Sexual Objectification and Rape-Supportive Attitudes as Predictors of How Sex is Negotiated in Men and Women

AbstractHow sex is negotiated has reached greater interest because a lack of consent is considered to be a risk factor for sexual violence. However, the mechanisms underlying sexual consent still remain unexplored. The purpose of the present study was to examine the link between rape-supportive attitudes and objectification, as experienced by women and perpetrated by men, in the context of specific domains relevant to the establishment and negotiation of sexual consent, i.e., attitudes, beliefs and behaviors. The sample comprised 1682 participants (21.5% male, 78.5% female) aged 18–66 years (M = 23.41; SD = 6.96). In women, negotiation of consent was predicted both directly and indirectly by being sexually objectified by men, rape attitudes playing a mediating role. Women who were objectified reported lower efficacy with respect to asking for consent and considered explicit establishment of consent as important. In men, only the perpetration of unwanted sexual advances predicted how they negotiate consent, in which rape attitudes played a mediating role (indicating a maladaptive pattern of negotiation). Our findings could be useful for the design and implementation of intervention programs that address both victims and perpetrators of violence.
The Future of Work: Augmentation or Stunting?
Authors: Furendal Markus , Jebari Karim 
Published: May 2023

AbstractThe last decade has seen significant improvements in artificial intelligence (AI) technologies, including robotics, machine vision, speech recognition, and text generation. Increasing automation will undoubtedly affect the future of work, and discussions on how the development of AI in the workplace will impact labor markets often include two scenarios: (1) labor replacement and (2) labor enabling. The former involves replacing workers with machines, while the latter assumes that human–machine cooperation can significantly improve worker productivity. In this context, it is often argued that (1) could lead to mass unemployment and that (2) therefore would be more desirable. We argue, however, that the labor-enabling scenario conflates two distinct possibilities. On the one hand, technology can increase productivity while also promoting “the goods of work,” such as the opportunity to pursue excellence, experience a sense of community, and contribute to society (human augmentation). On the other hand, higher productivity can also be achieved in a way that reduces opportunities for the “goods of work” and/or increases “the bads of work,” such as injury, reduced physical and mental health, reduction of autonomy, privacy, and human dignity (human stunting). We outline the differences of these outcomes and discuss the implications for the labor market in the context of contemporaneous discussions on the value of work and human wellbeing.
Simulations of common-envelope evolution in binary stellar systems: physical models and numerical techniques
Authors: Röpke Friedrich K. , De Marco Orsola 
Published: May 2023

AbstractWhen the primary star in a close binary system evolves into a giant and engulfs its companion, its core and the companion temporarily orbit each other inside a common envelope. Drag forces transfer orbital energy and angular momentum to the envelope material. Depending on the efficiency of this process, the envelope may be ejected leaving behind a tight remnant binary system of two stellar cores, or the cores merge retaining part of the envelope material. The exact outcome of common-envelope evolution is critical for in the formation of X-ray binaries, supernova progenitors, the progenitors of compact-object mergers that emit detectable gravitational waves, and many other objects of fundamental astrophysical relevance. The wide ranges of spatial and temporal timescales that characterize common-envelope interactions and the lack of spatial symmetries present a substantial challenge to generating consistent models. Therefore, these critical phases are one of the largest sources for uncertainty in classical treatments of binary stellar evolution. Three-dimensional hydrodynamic simulations of at least part of the common-envelope interaction are the key to gain predictive power in modeling common-envelope evolution. We review the development of theoretical concepts and numerical approaches for such three-dimensional hydrodynamic simulations. The inherent multi-physics, multi-scale challenges have resulted in a wide variety of approximations and numerical techniques to be exercised on the problem. We summarize the simulations published to date and their main results. Given the recent rapid progress, a sound understanding of the physics of common-envelope interactions is within reach and thus there is hope that one of the remaining fundamental problems of stellar astrophysics may be solved before long.
Revaluation of the Portable Art of Northern Iberia: a Magdalenian Decorated Bone Tube from Torre (Basque Country, Spain)

Published: May 2023

AbstractA decorated ulna of a gannet (Morus bassanus) was found in 1966 during the exploration of the archaeological site of Torre cave (Gipuzkoa, northern Iberian Peninsula). The present study offers a new appraisal of this truly outstanding art object through a technological and stylistic analysis enriched by more recent finds. What makes this object extraordinary is the fact that it is one of the most complete specimens in the Iberian Peninsula. Moreover, the Torre tube is one of the few remains with peri-cylindrical decoration displaying a complex combination of motifs. It is profusely decorated with figurative representations (deer, horse, ibex, chamois, aurochs and an anthropomorph) and signs (single lines, parallel lines, zigzags, etc.) in two rows in opposite directions. The tube resembles objects from other Magdalenian sites in Cantabrian Spain and the Pyrenees, which corroborate the exchange of technical and iconographic behaviour.
