Summary
Background
There is a lack of knowledge on how people at increased risk of severe illness from Coronavirus disease 2019 (COVID-19) experienced the infection control measures. This study aimed to explore their perspectives and needs during the coronavirus outbreak.

Methods
A qualitative longitudinal interview study was conducted in Austria during lockdown due to COVID-19 containment and afterwards. People older than 65 years of age and/or affected by a chronic medical condition participated in individual telephone interviews at two time points. Thematic analysis was used to analyze the data and saturation was defined as no new emerging concepts in at least 10 subsequent interviews.

Results
Thematic saturation was reached when 33 individuals (75.8% female, mean age ± standard deviation [SD] 73.7±10.9 years) were included. A total of 44 lower level concepts were extracted and summarized into 6 higher level concepts. They included (i) a general positive attitude toward COVID-19 measures, (ii) challenges of being isolated from the community, (iii) deterioration of health status, (iv) difficulties with measures due to their health condition, (v) lack of physical contact and (vi) lack of information versus overload. Participants suggested environmental adaptations for strengthening resilience in people at increased risk of severe illness from COVID-19.

Conclusion
Strategies and interventions are needed to support people at risk under pandemic conditions. Their perceptions and needs should be addressed to reduce the potential deterioration of health conditions and ensure well-being even during prolonged periods of crisis.
Ankle fusion with tibiotalocalcaneal retrograde nail for fragility ankle fractures: outcomes at a major trauma centre
Authors: Lu Victor , Tennyson Maria , Zhang James , Thahir Azeem , Zhou Andrew , Krkovic Matija 
Published: November 2021

Abstract
Purpose
Fragility ankles fractures in the geriatric population are challenging to manage, due to fracture instability, soft tissue compromise, and patient co-morbidities. Traditional management options include open reduction internal fixation, or conservative treatment, both of which are fraught with high complication rates. We aimed to present functional outcomes of elderly patients with fragility ankle fractures treated with retrograde ankle fusion nails.

Methods
A retrospective observational study was performed on patients who underwent intramedullary nailing with a tibiotalocalcaneal nail. Twenty patients met the inclusion criteria of being over sixty and having multiple co-morbidities. Patient demographics, AO/OTA fracture classification, intra-operative and post-operative complications, time to mobilisation and union, AOFAS and Olerud-Molander scores, and patient mobility were recorded.

Results
There were seven males and thirteen females, with a mean age of 77.82 years old, five of whom are type 2 diabetics. Thirteen patients returned to their pre-operative mobility state, and the average Charlson Co-morbidity Index (CCI) was 5.05. Patients with a low CCI are more likely to return to pre-operative mobility status (p = 0.16; OR = 4.00). All patients achieved radiographical union, taking on average between 92.5 days and 144.6 days. The mean post-operative AOFAS and Olerud-Molander scores were 53.0 and 50.9, respectively. There were four cases of superficial infection, four cases of broken or loose distal locking screws. There were no deep infections, periprosthetic fractures, nail breakages, or non-unions.

Conclusion
Tibiotalocalcaneal nailing is an effective and safe option for managing unstable ankle fractures in the elderly. This technique leads to lower complication rates and earlier mobilisation than traditional fixation methods.
Effects of suicide prevention videos developed by and targeting adolescents: a randomized controlled trial

Published: November 2021

AbstractSuicide prevention videos featuring young people’s personal narratives of hope and recovery are increasingly used in suicide prevention, but research on their effects is scarce. A double-blind randomized controlled trial was conducted to test the effects of a suicide prevention video featuring an adolescent mastering his suicidal ideation by getting help on 14 to 19-year-olds.N = 299 adolescents were randomly allocated to watch the intervention video (n = 148) or a control video unrelated to mental health (n = 151). Questionnaire data were collected before (T1) and immediately after exposure (T2), and 4 weeks later (T3). Data were analyzed with a repeated-measures ANCOVA. The primary outcome was suicidal ideation, assessed with the Reasons for Living Inventory for Adolescents. Secondary outcomes were help-seeking intentions, attitudes towards suicide, stigmatization of suicidality, and mood. There was an immediate beneficial effect of the intervention on suicidal ideation (T2mean change from baseline within intervention groupMChange = − 0.16 [95% CI − 0.20 to − 0.12], mean difference compared to control groupMDiff = − 0.09 [95% CI − 0.15 to − 0.03],ηp2 = 0.03), which was not maintained atT3. Participants reported significantly higher help-seeking intentions, which was maintained at 4-week follow-up. They also reported a sustained reduction of favorable attitudes to suicide. Effects on suicidal ideation were mediated by identification with the featured protagonist. Adolescents appear to benefit from suicide prevention narratives featuring personal stories from peers on coping with suicidal ideation and help-seeking.Trial registrationDRKS00017405; 24/09/19; retrospectively registered.
Effective transfer entropy to measure information flows in credit markets
Authors: Caserini Nicoló Andrea , Pagnottoni Paolo 
Published: November 2021

AbstractIn this paper we propose to study the dynamics of financial contagion between the credit default swap (CDS) and the sovereign bond markets through effective transfer entropy, a model-free methodology which enables to overcome the required hypotheses of classical price discovery measures in the statistical and econometric literature, without being restricted to linear dynamics. By means of effective transfer entropy we correct for small sample biases which affect the traditional Shannon transfer entropy, as well as we are able to conduct inference on the estimated directional information flows. In our empirical application, we analyze the CDS and bond market data for eight countries of the European Union, and aim to discover which of the two assets is faster at incorporating the information on the credit risk of the underlying sovereign. Our results show a clear and statistically significant prominence of the bond market for pricing the sovereign credit risk, especially during the crisis period. During the post-crisis period, instead, a few countries behave dissimilarly from the others, in particular Spain and the Netherlands.

AbstractThe invasive spotted-wing drosophila,Drosophila suzukii,is a major pest of fruit crops worldwide. Management ofD. suzukiirelies heavily on chemical control in both organic and conventional systems, and there is a need to develop more sustainable management practices. We evaluated the efficacy of three colors of plastic mulches at reducing populations ofD. suzukiiin fall-bearing raspberry and assessed the mulches’ impacts on canopy microclimate factors relevant toD. suzukii. Black, white, and metallic plastic mulches reduced adultD. suzukiipopulations by 42–51% and larval populations by 52–72% compared to the grower standard. The mulches did not change canopy temperature or relative humidity, but metallic mulches increased canopy light intensity compared to the black mulch. Radiance in the visible spectrum (401–680 nm) was higher for the white and metallic mulch plots, but the black mulch plots did not differ from the control. In the UV spectrum (380–400 nm), all three plastic mulches had higher radiance than the control plots. Future studies will determine whether changes in radiance are associated with the observed reduction inD. suzukiipopulations. Plastic mulches are a promising cultural practice for managingD. suzukiisince they can reduce adult and larval populations and could be incorporated into an integrated pest management program in both organic and conventional systems.
“White, Tall, Top, Masculine, Muscular”: Narratives of Intracommunity Stigma in Young Sexual Minority Men’s Experience on Mobile Apps

Published: November 2021

AbstractWhat forms of intracommunity stigma do young sexual minority men narrate as they participate in communities through mobile apps? In a content analysis of 32 interviews with a racially diverse sample of young sexual minority men (ages 19–25; 84.4% non-White) from four regions of the USA, a majority of men (62.5%) spontaneously discussed mobile apps (e.g., Grindr, Scruff) when asked about their experience of community more broadly. Men’s narratives revealed engagement with intracommunity stigma related to body size, race/ethnicity, gender expression, and sexual position (e.g., bottom). Stigma related to HIV status, substance use, and social class were not spontaneously narrated in response to questions about men’s experience in communities. Expressions of stigma were frequently experienced intersectionally, particularly regarding racialized stereotype expectations (e.g., “Asian men are twinks, effeminate”). We discuss the ways in which sexual minority men reproduce dominant ideologies related to racism, misogyny, and masculine body ideals as they engage with one another on mobile apps. To the extent that many young men rely on mobile apps for community connection, their experiences of community might serve to exacerbate, rather than ameliorate, the deleterious impact of stigma.
Active First Movers vs. Late Free-Riders? An Empirical Analysis of UN PRI Signatories’ Commitment

Published: November 2021

AbstractJoining voluntary thematic initiatives can be a means for firms to legitimate their business activities. However, a lack of review mechanisms could create incentives for free-riding. This might lead to a lower commitment to the initiative’s principles, and endanger its credibility and its members’ legitimacy benefits. Whether members of voluntary initiatives take advantage of the opportunity to free-ride has not been analyzed empirically so far. To fill this research gap, we investigate from an institutional theory perspective the actual implementation behavior of publicly listed signatories of the United Nations Principles for Responsible Investment (UN PRI) in a difference-in-differences and an event study setting. Our empirical results show that, after signing, UN PRI signatories integrate environmental, social, and governance (ESG) criteria in their business activities significantly more than matched non-signatories from the financial sector, indicating the commitment of the signatories to the UN PRI in general. However, while the initial members show a high commitment to the initiative’s principles by increasing their ESG integration performance substantially, new members signing at a later stage of the initiative perform considerably less, and thus undermine the UN PRI’s credibility. We derive implications for voluntary thematic initiatives to avoid such a development.

Published: November 2021

AbstractIn the paper, the authors discuss the first research effort to explore the transition from traditional teaching into distance teaching in Polish primary schools enforced by COVID-19. The first research question was addressed to primary school students and was dedicated to furnishing them with ICT equipment for crisis-prompted distance informatics learning. According to the obtained results, almost all Polish students during the pandemic have a technical opportunity to participate in distance learning and to use digital devices to develop their digital competences. Hence the second research question was addressed to the experts, demystifies whether the accessibility and the availability of ICTs could increase students’ informatics learning outcomes in out-of-school primary education settings. The obtained results reveal the significant importance of out-of-school informatics education in pandemic time. Moreover, in the first wave of pandemic, distance informatics education had the same or similar effect as if students learn informatics by themselves, without school lessons and teachers’ support. The obtained results should strengthen teachers and school leaders in making informed decisions during the shift into distance informatics education. Also, by investigating participants’ informatics learning outcomes and teacher preparedness and choices when implementing distance education, authors hope that the study may be helpful for policy-makers with the progressive changes in education and government support for informatics, especially in Poland, in making informed decisions to aid the transition into distance education as well as developing preparedness plans for future pandemics.
Feeling Wronged: The Value and Deontic Power of Moral Distress
Authors: Bagnoli Carla 
Published: November 2021

AbstractThis paper argues that moral distress is a distinctive category of reactive attitudes that are taken to be part and parcel of the social dynamics for recognition. While moral distress does not demonstrate evidence of wrongdoing, it does emotionally articulate a demand for normative attention that is addressed to others as moral providers. The argument for this characterization of the deontic power of moral distress builds upon two examples in which the cognitive value of the victim’s emotional experience is controversial: the case of micro-aggression, and the case of misplaced distress. In contrast to appraisal and perceptual models of distress, it is argued that its epistemic and normative value is dialogical rather than evidential, in that it presses claims that engage the audience in a normative discussion about the normative standing of the claimant, the proper grounds of the attitude, and the normative standards used to assess them.
Seed priming of plants aiding in drought stress tolerance and faster recovery: a review
Authors: Aswathi K. P. Raj , Kalaji Hazem M. , Puthur Jos T. 
Published: November 2021

AbstractDrought stress exposure adversely affects plant growth and productivity. Various seed priming techniques are experimented to mitigate the adverse effect of drought stress on plant performance. It is a low-cost and sustainable technology that proved to be of immense potential to enhance drought tolerance and increase crop productivity. Drought episodes are followed by recovery through rain or irrigation and help the plants to recuperate from the damages caused by drought stress. The severity of drought-associated damages determines the recovery kinetics of plants. Under the recurrent cycle of drought events, recovery kinetics has immense importance in predicting the stress tolerance potential and survival status of a plant. Many processes like DNA damage repair, de-novo synthesis of nucleic acids and proteins, osmotic adjustment through the accumulation of osmolytes, the potential activity of antioxidant machinery occurring during seed priming play a significant role during recovery from drought stress. Alleviation of the severity of drought stress through the accumulation of osmolytes, the augmented activity of antioxidant machinery, improved photosynthetic performance, and the upregulated expression of stress-responsive genes attributed by seed priming will complement the recovery from drought stress. Although the beneficial effects of seed priming on drought tolerance are well explored, priming influenced recovery mechanism has not been well explored. There is a lacuna in the field of research related to the beneficial effects of seed priming for recovery from drought stress, and that is the focus of this paper.
Controlled synthesis of dicalcium phosphate dihydrate (DCPD) from metastable solutions: insights into pathogenic calcification
Authors: Rafeek A. D. , Choi G. , Evans L. A. 
Published: November 2021

AbstractCalcium phosphate (CaP) compounds may occur in the body as abnormal pathogenic phases in addition to their normal occurrence as bones and teeth. Dicalcium phosphate dihydrate (DCPD; CaPO4·2H2O), along with other significant CaP phases, have been observed in pathogenic calcifications such as dental calculi, kidney stones and urinary stones. While other studies have shown that polar amino acids can inhibit the growth of CaPs, these studies have mainly focused on hydroxyapatite (HAp; Ca10(PO4)6(OH)2) formation from highly supersaturated solutions, while their effects on DCPD nucleation and growth from metastable solutions have been less thoroughly explored. By further elucidating the mechanisms of DCPD formation and the influence of amino acids on those mechanisms, insights may be gained into ways that amino acids could be used in treatment and prevention of unwanted calcifications. The current study involved seeded growth of DCPD from metastable solutions at constant pH in the presence of neutral, acidic and phosphorylated amino acid side chains. As a comparison, solutions were also seeded with calcium pyrophosphate (CPP; Ca2P2O7), a known calcium phosphate inhibitor. The results show that polar amino acids inhibit DCPD growth; this likely occurs due to electrostatic interactions between amino acid side groups and charged DCPD surfaces. Phosphoserine had the greatest inhibitory ability of the amino acids tested, with an effect equal to that of CPP. Clustering of DCPD crystals giving rise to a “chrysanthemum-like” morphology was noted with glutamic acid. This study concludes that molecules containing an increased number of polar side groups will enhance the inhibition of DCPD seeded growth from metastable solutions.

Published: November 2021

AbstractIn most middle schools, learning is segregated by discipline. Yet interdisciplinary approaches have been shown to cultivate creative thinking, support problem solving, and develop interest while supporting knowledge gains (NAE & NRC in STEM Integration in K-12 Education: Status, Prospects, and an Agenda for Research. National Academies Press, Washington, 2014). The Designing Biomimetic Robots project emphasizes problem-based learning to integrate engineering, science, and computational thinking (CT). During a 3 to 4-week unit, students study the natural world to learn how animals accomplish different tasks, then design a robot inspired by what they learned. The project engages students in science, engineering, and CT practices. Over the course of a 3-year project, we used a design-based research approach to: (1) identify and describe strategies and challenges that emerge from integrated curriculum design, (2) explicate how a balance of integrated disciplines can provide opportunities for student participation in science, engineering, and CT practices, and (3) explore how a technology design task can support students’ participation in integrated learning. Data from three focal groups (one from each year of the project) suggest that a focused design task, supported by explicit and targeted supports for science, CT, and engineering practices, led to a student technology design process that was driven by disciplinary understanding. This work highlights the importance of drawing out and prioritizing alignments between disciplines (Barber in Educ Des, 2(8), 2015), to enable integrated learning. Additionally, this work demonstrates how a technology design task can support student learning across disciplines, and how engaging in CT practices can further help students draw these connections.
Ist Religion lehrbar? Diskurse über religiöse Bildung im spätantiken Christentum
Authors: Gemeinhardt Peter 
Published: November 2021

ZusammenfassungReligion und Bildung stehen in einem Spannungsverhältnis zueinander, das fruchtbar, aber auch konflikthaft ausgestaltet sein kann. Das galt bereits für das frühe Christentum. Dem Befehl Jesu folgend galt es, Menschen vor und nach der Taufe Bildung zuteil werden zu lassen. Aber kann man Glauben „machen“? Und wenn ja, wie? Der Beitrag beleuchtet zunächst die Kritik paganer Philosophen am „bildungslosen“ Christentum und dessen Ansätze zu religiöser Unterweisung. Er geht sodann auf das Bildungshandeln im Katechumenat des 4. und 5. Jahrhunderts ein und untersucht, wie das Lehren des Glaubens in didaktischer Hinsicht reflektiert wurde. Schließlich nimmt er eine anscheinend bildungsabstinente Gruppe in den Blick: das Mönchtum, das sich bei näherem Hinsehen als Bildungsbewegung sui generis entpuppt. Der Beitrag legt die Triangulation christlicher Bildung zwischen Lehrenden und Lernenden sowie Gott als eigentlichem Lehrer offen; er schließt mit Überlegungen, wie die spätantiken Impulse für modernes (religiöses) Bildungshandeln erschlossen werden können.
The In Situ Ion Irradiation Toolbox: Time-Resolved Structure and Property Measurements
Authors: Lang E. , Dennett C. A. , Madden N. , Hattar K. 
Published: November 2021

AbstractThe dynamic interactions of ions with matter drive a host of complex evolution mechanisms, requiring monitoring on short spatial and temporal scales to gain a full picture of a material response. Understanding the evolution of materials under ion irradiation and displacement damage is vital for many fields, including semiconductor processing, nuclear reactors, and space systems. Despite materials in service having a dynamic response to radiation damage, typical characterization is performed post-irradiation, washing out all information from transient processes. Characterizing active processes in situ during irradiation allows the mechanisms at play during the dynamic ion-material interaction process to be deciphered. In this review, we examine the in situ characterization techniques utilized for examining material structure, composition, and property evolution under ion irradiation. Covering analyses of microstructure, surface composition, and material properties, this work offers a perspective on the recent advances in methods for in situ monitoring of materials under ion irradiation, including a future outlook examining the role of complementary and combined characterization techniques in understanding dynamic materials evolution.
