AbstractWe provide a culturomics analysis of the cultivable bacterial communities of the crop, midgut and hindgut compartments, as well as the ovaries, of the invasive insect Vespa velutina, along with a cultivation‐independent analysis of samples of the same nest through 16S rRNA amplicon sequencing. The Vespa velutina bacterial symbiont community was dominated by the genera Convivina, Fructobacillus, Lactiplantibacillus, Lactococcus, Sphingomonas and Spiroplasma. Lactococcus lactis and Lactiplantibacillus plantarum represented generalist core lactic acid bacteria (LAB) symbionts, while Convivina species and Fructobacillus fructosus represented highly specialised core LAB symbionts with strongly reduced genome sizes. Sphingomonas and Spiroplasma were the only non‐LAB core symbionts but were not isolated. Convivina bacteria were particularly enriched in the hornet crop and included Convivina intestini, a species adapted towards amino acid metabolism, and Convivina praedatoris sp. nov. which was adapted towards carbohydrate metabolism.

Published: May 2023

AbstractEven though BiFeO3–BaTiO3 (BF–BT) with high Curie temperature and excellent piezoelectric properties is very suitable for high‐temperature applications, its rapid reduction in resistivity with temperature limits its further application. So far, there is no effective method to improve the resistivity of BF–BT at a high‐temperature state. In this work, hot‐press sintering combined with an oxygen atmosphere was used to prepare (1 − x)BF–xBT (x = 0.2–0.33) ceramics for the first time, which reduced the sintering temperature from 1000 to 920°C. The controllable grain size can be achieved by adjusting the sintering temperature and the applied pressure. The X‐ray photoelectron spectroscopy results confirmed that using hot‐press sintering effectively avoided the generation of heterovalent Fe ions, and the resistivity of BF–BT ceramics at the high‐temperature stage was improved by two orders of magnitude. It was found that hot‐press sintering can cause the oriented growth of the sample along the (1 1 0) direction, and further refined X‐ray diffraction was used to accurately analyze the changes in the lattice structure. The hot‐press sintered samples obtained larger polarization strength, especially the electro‐induced strain showed excellent temperature stability in the wide temperature range of 30–170°C. Hot‐pressing sintering combined with an oxygen atmosphere is more suitable for preparing high insulation and electrical breakdown resistance ceramics.

AbstractBackgroundThe present study aimed to describe the dietary patterns of a population from Brazil and another from Colombia with respect to understanding their determinants, similarities and differences.MethodsAn analytical cross‐sectional study was conducted based on secondary data. The dietary patterns of the adult population of Pernambuco, Brazil, as well as those of the adult population of Antioquia, Colombia, were analysed using principal component analysis method with orthogonal varimax rotation, and a Poisson regression with robust variance was used to verify the association between eating patterns and socio‐economic variables.ResultsIn each population, three eating patterns were identified. One of them related to healthy eating, named “Prudent”, was identified in the two populations analysed. In Pernambuco, a food pattern consisting exclusively of foods with some degree of processing was verified, entitled “Processed”. The food culture was reflected in the pattern called “Traditional‐Regional” in Pernambuco and the “Traditional” and “Regional” patterns in Antioquia.ConclusionsIncome, education, age, family size, food security status and area of residence were presented as determinants of dietary patterns in both populations. Elements of the food transition were found, which seems to have happened more rapidly in Pernambuco. The food groups that make up the dietary patterns of each population are similar, but the foods that constitute them present differences due to their availability depending on aspects such as climate, soil quality, access to water, local culture and food tradition.

AbstractParenting induces many neurological and behavioral changes that enable parents to rear offspring. Vasopressin plays an important role in this process via its effects on cognition, affect, and neuroplasticity, and in some cases, via interactions with decreased parental androgens. Thus far, the role of these hormones has been primarily studied in rodents. To address this gap, we explored vasopressin receptors and androgens in titi monkeys, a pair‐bonding and biparental primate species. In Studies 1 and 2, we used receptor autoradiography to correlate arginine vasopressin receptor 1a (AVPR1a) binding in the hippocampus (Study 1, n = 10) and the rest of the forebrain (Study 2, n = 23) with parental status, parental experience, parity, infant carrying, and pair affiliation. We found that parents exhibited lower AVPR1a binding than non‐parents throughout most brain regions assessed, with especially strong effects in the hippocampus (β = −.61), superior colliculus (β = −.88), lateral septum (β = −.35), and medial preoptic area (β = −.29). The other measures of parental experience also tended to be negatively associated with AVPR1a binding across different brain regions. In Study 3 (n = 44), we compared pre‐ and postpartum urinary androgen levels in parents and non‐parents and found that mothers exhibited a sustained androgen decrease across 3–4 months postpartum (relative to 3 months prepartum; β ranged from −.72 to −.62 for different comparisons). For males, we found that multiparous fathers exhibited decreased androgen levels at 1–2 weeks postpartum (β = −.25) and at 3–4 months postpartum (β = −.40) compared to the prepartum, indicating both immediate and long‐term reductions with subsequent paternal experience. Together, the results of this study suggest that decreases in AVPR1a binding and circulating androgens are associated with parental behavior and physiology in titi monkeys.

Published: May 2023

AbstractObjectiveHealth care workers have been exposed to a variety of practical and emotional challenges because of the Covid‐19 pandemic, leaving them vulnerable to experiencing moral injury and distress. However, there is currently sparse research which directly explores such experiences. This study aimed to explore and characterise the experiences and impacts of moral injury and distress among health care workers during the pandemic.MethodsTwenty semi‐structured interviews were conducted with health care workers employed across both mental and physical health care services. Interviews were analysed from a critical realist perspective using thematic analysis.ResultsThree key themes were identified: attitudes towards moral injury, experiences of moral injury and consequences of moral injury. Participants appeared to identify with the idea of acting against their morals to varying extents based on their job roles. Participants experienced a range of potentially morally injurious and distressing events throughout the pandemic and many ultimately felt that they provided sub‐standard levels of care due to extreme pressures on services. Detrimental impacts upon wellbeing were commonly reported, including high levels of emotional distress and feelings of guilt and shame. Some reported a loss of enthusiasm for their job and a desire to leave the profession entirely.ConclusionMoral injury and distress presents a real concern for staff wellbeing and retention within the profession. During and beyond the Covid‐19 pandemic, there is an urgent need for health care providers to implement wider strategies to target moral injury and distress, and support staff within health care settings.

SummaryIn rice breeding, thermosensitive genic male sterility (TGMS) lines based on the tms5 locus have been extensively employed. Here, we reported a novel rice TGMS line ostms15 (Oryza sativa ssp. japonica ZH11) which show male sterility under high temperature and fertility under low temperature. Field evaluation from 2018 to 2021 revealed that its sterility under high temperature is more stable than that of tms5 (ZH11), even with occasional low temperature periods, indicating its considerable value for rice breeding. OsTMS15 encodes an LRR‐RLK protein MULTIPLE SPOROCYTE1 (MSP1) which was reported to interact with its ligand to initiate tapetum development for pollen formation. In ostms15, a point mutation from GTA (Val) to GAA (Glu) in its TIR motif of the LRR region led to the TGMS phenotype. Cellular observation and gene expression analysis showed that the tapetum is still present in ostms15, while its function was substantially impaired under high temperature. However, its tapetum function was restored under low temperature. The interaction between mOsTMS15 and its ligand was reduced while this interaction was partially restored under low temperature. Slow development was reported to be a general mechanism of P/TGMS fertility restoration. We propose that the recovered protein interaction together with slow development under low temperature compensates for the defective tapetum initiation, which further restores ostms15 fertility. We used base editing to create a number of TGMS lines with different base substitutions based on the OsTMS15 locus. This work may also facilitate the mechanistic investigation and breeding of other crops.
“Some days are much holier than others”: Relational uncertainty and partner influence in Christian dating couples' sexual intimacy negotiation
Authors: Leonard Hodges Arielle , Bevan Jennifer L. 
Published: May 2023

AbstractWhen intrafaith couples' religion strictly prohibits premarital sexual intercourse, negotiating sexual intimacy can become a multilayered process of identity negotiation that compounds the difficulty of sexual communication. Through the lens of relational turbulence theory, this study explored how devout Christian couples negotiate sexual intimacy by reanalyzing qualitative interview data the first author collected in 2017 from 16 self‐identified Christians (8 heterosexual couples). Seven themes revealed how relational uncertainty, partner interference, and partner facilitation manifested in the context of sexual intimacy negotiation. Themes of relational uncertainty experience and prevention includedassumption of shared values,relationship talk, andsexual behaviors as an uncertainty catalyst. Partner facilitation and interference emerged as themes of sexual escalation and de‐escalation includingsnowball effect, pinpointing underlying motivations for boundary violations,gatekeeping sexual temptation, anddrawing from shared values of sacrifice and prayer. These interpretive findings advance the literature on relational turbulence theory and provide Christian dating couples with practical advice for how to negotiate sexual intimacy in committed premarital relationships.
Is beta in agreement with the relatives? Using relative clause sentences to investigate MEG beta power dynamics during sentence comprehension
Authors: Lewis Ashley Glen , Schoffelen Jan‐Mathijs , Bastiaansen Marcel , Schriefers Herbert 
Published: May 2023

AbstractThere remains some debate about whether beta power effects observed during sentence comprehension reflect ongoing syntactic unification operations (beta‐syntax hypothesis), or instead reflect maintenance or updating of the sentence‐level representation (beta‐maintenance hypothesis). In this study, we used magnetoencephalography to investigate beta power neural dynamics while participants read relative clause sentences that were initially ambiguous between a subject‐ or an object‐relative reading. An additional condition included a grammatical violation at the disambiguation point in the relative clause sentences. The beta‐maintenance hypothesis predicts a decrease in beta power at the disambiguation point for unexpected (and less preferred) object‐relative clause sentences and grammatical violations, as both signal a need to update the sentence‐level representation. While the beta‐syntax hypothesis also predicts a beta power decrease for grammatical violations due to a disruption of syntactic unification operations, it instead predicts an increase in beta power for the object‐relative clause condition because syntactic unification at the point of disambiguation becomes more demanding. We observed decreased beta power for both the agreement violation and object‐relative clause conditions in typical left hemisphere language regions, which provides compelling support for the beta‐maintenance hypothesis. Mid‐frontal theta power effects were also present for grammatical violations and object‐relative clause sentences, suggesting that violations and unexpected sentence interpretations are registered as conflicts by the brain's domain‐general error detection system.
Representative bureaucracy and organizational attractiveness: An experimental study of symbolic representation of the US and UK police
Authors: Johnston Karen , Alberti Federica , Kravariti Foteini 
Published: May 2023

AbstractDrawing upon representative bureaucracy theory, this study investigates the relationship between passive and symbolic representation by examining the extent to which a more passively representative public organization would be attractive as an employer. The study involved a randomized survey experiment of members of the public in the US and UK. Overall, and contrary to the theory of representative bureaucracy, results show that women found a male‐dominated police department more attractive. The explanation for the results of the study may lie in bureaucratic reputation as a boundary condition of symbolic representation.
Traceability and foreign corporate accountability in mineral supply chains
Authors: Schöneich Svenja , Saulich Christina , Müller Melanie 
Published: May 2023

AbstractIndustrialized economies in the EU depend heavily on imports of minerals. The extraction and parts of the transport and processing of these minerals take place in the Global South and often bear high human rights and environmental risks. A lack of traceability in mineral supply chains makes it particularly difficult to hold companies accountable for negative environmental and social impacts of their operations and those of their suppliers. This paper analyses three mineral supply chains (copper, platinum, and gold) in order to develop propositions about how supply chain‐specific characteristics affect traceability and foreign corporate accountability (FCA) in mineral supply chains. The analytical framework focuses on three dimensions: geopolitical dynamics, industry characteristics, and private governance mechanisms. The authors argue that chain‐specific characteristics may foster or thwart traceability and FCA in mineral supply chains and thus provides a novel contribution to the debate on traceability and accountability in mineral supply chains.
"Keeping a Safe Confession Distance between Strangers": The Spatial Structure of Social Accessibility in Networked Communities and Risk Avoidance of Stranger Confessions
Authors: Xu Tongwen , Lyu Yunhong 
Published: May 2023

This study focuses on the spatial structure of stranger social accessibility in networked communities and risk avoidance when socializing with strangers. Using Confession Wall as an example, this study contends that community social media fosters new connections by compensating for accessibility issues between strangers in local communities through flexible mediation of online and offline social interactions. This connectivity minimizes the costs and risks of emotional interactions between strangers in semi-acquaintance communities. This compensation for social accessibility highlights the value of digital media, especially community social media as a geomedia, in energizing communities and facilitating interactions between strangers. This is crucial in understanding the emotional interactions between strangers and how they are mediated by community social media in settings where acquaintances and complete strangers intermingle.
Progressive lawsonite eclogitization of the oceanic crust: Implications for deep mass transfer in subduction zones
Authors: Hernández-Uribe David , Tsujimori Tatsuki 
Published: May 2023

Abstract
Lawsonite eclogites are major hosts of H2O and trace elements and thus key for long-term deep element cycling in subduction zones. Existing cycling models suggest that the subducting oceanic crust transforms to lawsonite-eclogite assemblages; yet the scarcity of lawsonite eclogites in the rock record questions to what extent the oceanic crust transforms to lawsonite-eclogite assemblages during subduction. Here, we use petrological modeling coupled with geodynamic calculations for a typical subduction zone to show that the occurrence of lawsonite eclogites is controlled by the maturation of the subduction zone. We find that lawsonite eclogite does not form in infant subduction zones; with time, the oceanic crust forms lawsonite assemblages, but prograde heating obliterates lawsonite except in rocks exhumed prior to such heating. Lawsonite-eclogite assemblages in the oceanic crust form and survive prograde metamorphism only in mature and cold subduction zones but still necessitate specific characteristics during exhumation to preserve lawsonite. We show that the stability of lawsonite in mature subduction zones is hindered by hybridization between the mafic crust and the overlaying mantle wedge material; by contrast, lawsonite proportion increases with intense seafloor alteration and Ca-Al metasomatism. These latter processes are thus key for enhancing recycling. We argue that lawsonite-driven mass cycling to the deep mantle is important in mature subduction zones, but the role of lawsonite eclogite in carrying mass deep into Earth in the infant stage of a subduction zone is minor.

Published: May 2023

ObjectivesTo synthesise evidence to determine whether, in contrast to medical male circumcision, traditional male circumcision (TMC) practices may contribute to HIV transmission and what the impacts of TMC are on the initiates, their families and societies.DesignSystematic review.Data sourcePubMed, CINHAL, SCOPUS, ProQuest, Cochrane database and Medline were searched between 15 and 30 October 2022.Eligibility criteria(1) Studies involving young men, young male adults, male adults and mixed male and female participants; (2) studies on TMC involving men living with HIV (married and non-married); (3) studies on TMC, HIV transmission and impact in low-income and middle-income countries; (4) qualitative, quantitative and mixed-method studies and (5) studies aimed at exploring TMC and how it contributes to HIV transmission and the impacts of HIV on circumcised men and their families.Data extractionData were extracted based on study details, study design, characteristics of participants and results.ResultA total of 18 studies were included: 11 were qualitative studies, five were quantitative studies and two were mixed-method studies. All the studies included were conducted in areas where TMC was performed (17 in Africa and one in Papua New Guinea). The review’s findings were categorised into themes: TMC as a cultural practice, consequences of not being traditionally circumcised on men and their families and TMC-related risk of HIV transmission.ConclusionThis systematic review highlights that TMC practice and HIV risk could negatively impact men and their families. Existing evidence suggests that little attention has been paid to men and their families experiencing the impacts of TMC and HIV risk factors. The findings recommend the need for health intervention programmes such as safe circumcision and safe sexual behaviours following TMC and efforts to address psychological and social challenges in communities practising TMC.PROSPERO registration numberCRD42022357788.

ObjectiveTo avoid the need for extensive adhesiolysis in patients with small bowel obstruction (SBO). We evaluated the feasibility of using advanced imaging, percutaneous access, and endoscopy as alternative therapies for SBO.DesignRetrospective case series (IDEAL [Idea, Development, Exploration, Assessment, and Long-term Study Collaborative] stages 1 and 2a).SettingSingle tertiary referral center.ParticipantsTwelve adults with chronic SBO resulting from inflammatory bowel disease, disseminated cancer, radiation, and/or adhesive disease. Participants were included if they underwent one of three novel access procedures. There were no exclusion criteria. The median age of participants was 67.5 years (range 42–81); two-thirds were women; and median American Society of Anesthesiology class was 3.InterventionsAll participants underwent one of three novel access methods, followed by wire-guided balloon dilation of a narrowed area of small bowel. These methods combined endoscopic, fluoroscopic, and surgical techniques. The techniques were (1) a purely endoscopic approach aided by an over-the-scope double-balloon device, (2) a combined endoscopic and percutaneous approach, and (3) a cut-down approach.Main outcome measuresProcedural success (defined as successful access to the small bowel and successful balloon dilation of the stenotic area). Secondary outcomes included major complications, recurrence, length of stay, and procedure time.ResultsProcedural success was achieved in 10 of 12 patients (83%). At the time of median follow-up of 10 months, recurrence of SBO was observed in two patients. In only one patient, the novel method did not change the treatment plan. No major complications occurred. Conventional operative intervention was avoided in all patients who achieved technical success with one of the novel approaches. The median postprocedure length of hospital stay was 4 days. Median procedure time was 135 min.ConclusionsNovel minimally invasive approaches to SBO represent feasible alternatives to surgical procedures in select patients. Further study should compare these approaches to standard ones as new methods are refined.
