AbstractThe European flat oyster (Ostrea edulis L.) is a bivalve naturally distributed across Europe, which was an integral part of human diets for centuries, until anthropogenic activities and disease outbreaks severely reduced wild populations. Despite a growing interest in genetic applications to support population management and aquaculture, a reference genome for this species is lacking to date. Here, we report a chromosome‐level assembly and annotation for the European Flat oyster genome, generated using Oxford Nanopore, Illumina, Dovetail OmniC™ proximity ligation and RNA sequencing. A contig assembly (N50: 2.38 Mb) was scaffolded into the expected karyotype of 10 pseudochromosomes. The final assembly is 935.13 Mb, with a scaffold‐N50 of 95.56 Mb, with a predicted repeat landscape dominated by unclassified elements specific to O. edulis. The assembly was verified for accuracy and completeness using multiple approaches, including a novel linkage map built with ddRAD‐Seq technology, comprising 4016 SNPs from four full‐sib families (eight parents and 163 F1 offspring). Annotation of the genome integrating multitissue transcriptome data, comparative protein evidence and ab‐initio gene prediction identified 35,699 protein‐coding genes. Chromosome‐level synteny was demonstrated against multiple high‐quality bivalve genome assemblies, including an O. edulis genome generated independently for a French O. edulis individual. Comparative genomics was used to characterize gene family expansions during Ostrea evolution that potentially facilitated adaptation. This new reference genome for European flat oyster will enable high‐resolution genomics in support of conservation and aquaculture initiatives, and improves our understanding of bivalve genome evolution.
The Attachment Versus Differentiation Debate: Bringing the Conversation to Parent–Child Relationships
Authors: Miller Elizabeth A. 
Published: August 2022

AbstractThis article contributes to the attachment versus differentiation debate, bringing the conversation to parent–child relationships. While attachment theory's (AT) approach emphasizes bonding, Bowen family systems theory's (BFST) differentiation approach emphasizes emotional boundaries. They both suggest that balancing autonomy and connection is important, but AT conceptualizes this in terms of the parent's ability to meet the child's needs for autonomy and connection, while BFST conceptualizes this in terms of the parent's and child's ability to be connected due to mutual respect for each other's emotional boundaries. They similarly recognize that: (1) emotionally mature parents respect children individuality, (2) emotionally immature parents may project their needs and wishes onto children, and (3) emotionally mature parents focus on calming themselves to help their children to be calm. They differ in that: (1) BFST suggests that children may project their needs and wishes onto their parents and intrude on their parents' emotional boundaries, and AT does not conceptualize this; (2) BFST suggests that caregiver over‐involvement may be experienced as positive for a child and program them to be excessively needy, and AT suggests that caregiver over‐involvement is negative for children and neediness is caused by under‐involved caregiving; and (3) BFST suggests that therapists should not try to be a parent to their clients as this can replicate the fusion that the client experienced with their parents, and AT suggests that therapists should try to be like a good parent to their clients to help them to develop more secure attachment styles.

Published: August 2022

AbstractObjectiveThis study aimed to investigate the psychometric properties of the Coparenting Relationship Scale (CRS) in Chinese samples.BackgroundThe coparenting relationship serves an important role in raising children. The CRS was originally developed to measure the multidimensionality of the coparenting relationship. However, its latent structure and psychometric properties have not been extensively addressed, particularly in non‐Western cultures.MethodData were collected from a sample of 991 Chinese families (991 mothers, 967 fathers, 31–57 years of age). Confirmatory factor analyses were utilized to provide evidence of the theoretical factorial structure. Internal consistency was examined by Cronbach's α and omega coefficients. Correlations with the Dyadic Adjustment Scale were to verify criterion validity. Configural, metric, scalar, and residual variance invariance were examined across the gender of parents in dyadic perspective.ResultsIn contrast to a poor fit for the seven‐factor structure of the original 35‐item CRS, the Chinese version of the CRS (CRS‐C) showed a good fit in a six‐factor structure with 27 items. The CRS‐C showed strict measurement invariance across gender of the parent, satisfactory internal consistency, and criterion‐related validity as indicated by marital quality.ConclusionsThese findings provided preliminary evidence that the CRS‐C is reliable and valid for measuring the coparenting relationship among Chinese parents.ImplicationsCoparenting relationship and its measurement will benefit from attention in non‐Western contexts and cross‐cultural studies.

AbstractObjectiveThis study aimed to understand how periodic shifts in financial cutbacks and fears of contracting COVID‐19 contributed to children's externalizing behaviors due to increases in maternal stress among low‐income Latina mothers during the first 10 months of the COVID‐19 pandemic.BackgroundThe COVID‐19 pandemic caused widespread health, economic, and psychological consequences for families and children. The Latino community is particularly vulnerable to the economic and health risks of this pandemic as a consequence of systemic oppression. The family stress model suggests that these family stressors will have psychological repercussions to parents, and downstream behavioral consequences to children.MethodWe examined both the within‐ and between‐person impacts of worry surrounding contracting the virus and the economic consequences of the pandemic on maternal stress and child externalizing behaviors. Participants were 73 Latina mothers who completed assessments an average eight times across the first  10 months of the COVID‐19 pandemic. At each assessment time, the mother was asked about worries surrounding contracting the virus, economic cutbacks the family was making, her perceived stress, and her child's externalizing behaviors during a brief phone call.ResultsBetween‐families, higher economic cutbacks indirectly increased child externalizing behaviors through maternal stress. The within‐family model revealed that at assessments when mothers expressed greater worry about contracting the COVID‐19 virus, they also reported greater stress. Further, at the within‐person level, a mother's greater experience of stress was associated with greater reports of child externalizing behaviors, though the indirect association between COVID‐19 contract worry and child externalizing behaviors through maternal stress was not significant.ConclusionsAcross the first 10 months of the COVID‐19 pandemic, the children in Latino families participating in this research exhibited more externalizing behaviors among families that engaged in more financial cutbacks as a function maternal stress. However, periodic spikes in Latina mothers' fears of contracting COVID‐19 contributed to periodic spikes in stress, which predicted periodic spikes in child externalizing behaviors.ImplicationsGreater effort toward social policy that provides economic support for vulnerable families before periods of increased societal stress and greater protections for workers with limited sick leave and schedule flexibility will help promote resilience to future crises among low‐income Latino families.
Sympatric soil biota mitigate a warmer‐drier climate for Bouteloua gracilis

Published: August 2022

AbstractClimate change is altering temperature and precipitation, resulting in widespread plant mortality and shifts in plant distributions. Plants growing in soil types with low water holding capacity may experience intensified effects of reduced water availability as a result of climate change. Furthermore, complex biotic interactions between plants and soil organisms may mitigate or exacerbate the effects of climate change. This 3‐year field experiment observed the performance of Bouteloua gracilis ecotypes that were transplanted across an environmental gradient with either sympatric soil from the seed source location or allopatric soil from the location that plants were transplanted into. We also inoculated plants with either sympatric or allopatric soil biotic communities to test: (1) how changes in climate alone influence plant growth, (2) how soil types interact with climate to influence plant growth, and (3) the role of soil biota in mitigating plant migration to novel environments. As expected, plants moved to cooler‐wetter sites exhibited enhanced growth; however, plants moved to warmer‐drier sites responded variably depending on the provenance of their soil and inoculum. Soil and inoculum provenance had little influence on the performance of plants moved to cooler‐wetter sites, but at warmer‐drier sites they were important predictors of plant biomass, seed set, and specific leaf area. Specifically, transplants inoculated with their sympatric soil biota and grown in their sympatric soil were as large as or larger than reference plants grown at the seed source locations; however, individuals inoculated with allopatric soil biota were smaller than reference site individuals at warmer, drier sites. These findings demonstrate complicated plant responses to various aspects of environmental novelty where communities of soil organisms may help ameliorate stress. The belowground microbiome of plants should be considered to predict the responses of vegetation more accurately to climate change.
Migrant visits over time: Ethnographic returning and the technological turn
Authors: Baldassar Loretta 
Published: August 2022

AbstractThis paper reflects on four decades of research (via ethnographic returning) to explore the social transformations in travel and communication technologies that have impacted the lived experiences, and consequently the theoretical conceptualization, of migrant visits. A comparison of migration waves between Italy and Australia reveals both continuities in visiting experience as deeply relational practices that facilitate a mutuality of being, but also transformations brought about by the technological turn. Visits take on different meanings depending on individual/ family life stage, generation, and community and national histories. The capacity for both physical and virtual copresence must be understood as coconstitutive, requiring a temporal perspective. The experiences of immobile migrants in residential care suggest that, in the context of rich histories of copresence over time, digital kinning can provide the capacity to share a mutuality of being that safeguards the socio‐relational ties of individual and collective identities and belonging that make us human.

Published: August 2022

AbstractObjectiveScalp hair is among the most exposed parts of the human body, yet the impact of visible and UV light on hair lipids, an important structural component of hair, is poorly researched. We have used lipidomics, a broad‐based approach to measure lipids in samples, which has hitherto not been applied to UV‐exposed hair in the published literature, and could allow for a wider understanding of how UV light impacts on specific hair lipids.MethodsMixed blonde Caucasian hair switches were divided into two groups of five, with half of the hair switches exposed to UV and visible light mimicking normal daytime exposure and half left unexposed. LC–MS lipidomics was used to profile the lipids in the hair samples.ResultsA total of 791 lipids and 32 lipid classes with tentative identifications were detected in the hair samples. Nineteen lipid classes and 397 lipids differed between UV‐treated and non‐treated hair. The main lipid classes that differed were vitamin A fatty acid esters, sterol esters, several ceramides, mono‐, di‐ and triglycerides, phosphatidylethanolamines (all decreased in UV‐exposed hair) and bismonoacylglycerolphosphates, acylcarnitines and acylglycines (all increased in UV‐exposed hair). Most detected lipids were decreased in UV‐exposed hair, supporting earlier work that has found that UV exposure causes oxidation of lipids which would result in a decrease in most lipid classes.ConclusionLight exposure to hair has a widespread impact on the hair lipidome. This study also adds to the emerging literature on the hair lipidome, broadening the range of lipid classes reported in hair.

Published: August 2022

AbstractObjectivesAdherence to the daily use of dental floss in childhood is recommended by various international health institutions/organizations. This systematic review (PROSPERO number CRD42020205232) aims to evaluate the prevalence of dental floss use in deciduous dentition.Materials and methodsA systematic review was conducted in six databases (B‐on, Cochrane Library, PubMed, Scielo, Science Direct and Web of Science) up to December 2020. The CoCoPop mnemonic allowed for obtaining 2333 articles and resulted in the inclusion of 7 observational studies that evaluated the prevalence of dental floss use (primary outcome) in children up to 6 years old. The Joanna Briggs Institute critical appraisal checklist was used to evaluate the risk of bias, showing that most articles presented good quality. Meta‐analyses were performed using the proportion of dental floss use (yes or once/day) and the random effects model.ResultsThe meta‐analysis showed a prevalence of dental floss use of only 12.60% (95% CI: 7.69%–18.52%) based on studies with high heterogeneity of results (I2 = 94.75%; 95% CI: 91.44%–96.78%). Six of the seven studies showed that more than 70% of children never used dental floss.ConclusionsA low prevalence of dental floss use was observed in children up to 6 years old. Given the diversity of evaluating the use of dental floss, different options should be the target of standardization in future studies.
Microstructural evolution during thermal shock process and the residual strength of Si3N4 ceramics
Authors: Yang Xiao , Liu Xuejian , Zhang Hui , Huang Zhengren 
Published: August 2022

AbstractThermal shock resistance of silicon nitride was investigated from aspects of residual strength and microstructure, using a water quenching method. The residual strengths after 800 and 1000°C thermal shock polarized as higher ones and much lower ones, and reasons for the huge disparity are explored. With heat treatment temperature getting higher, the inner small pores rush to and aggregate in the surface layer of the samples. When the heat treatment reaches 1400°C, a darker subsurface layer is observed, which is caused by the loss of most Al and Y elements. Moreover, many more small pores are found in this layer, acting as the dissipation sources, they protect the material strength by releasing the intense thermal stress. But this subsurface layer disappears during the natural cooling down to 600°C as Al and Y uniformly redistributed in extended oxidation, then huge cracks form on the surface layer undergoing much smaller thermal stress from 600 to 0°C. Moreover, the bonding Y and Si can be oxidized into two types of Y2Si2O7 crystals that improve the thermal shock performance of Si3N4.

Published: August 2022

AbstractIn this study, NH4CoPO4·H2O (ACP) platelets were synthesized from NH4H2PO4 and Co(OH)2 by wet milling process using a bead mill. ACP is one of the precursors of LiCoPO4 (LCP) cathode materials for Li‐ion batteries. In the wet milling, ACP large platelets were synthesized in a short time at the beginning, and the large platelets were gradually cleaved into the smaller platelets. The lateral sizes of the ACP platelets were several 10 μm at 30 min and about 10 μm at 5 h. It was found that the ACP platelets were synthesized efficiently by using the bead mill as a promising machine for the scale‐up in manufacturing. The ACP platelets were converted into LCP by mixing with Li2CO3 and heating, whereas platelet shapes were retained. The initial discharge capacities of the cathodes using the LCP platelets converted from the ACP of 30 min and 5 h milling were 70 and 95 mAh/g at 0.05 C, respectively. It is because the specific surface area of the latter sample (3.3 m2/g) was larger than that of the former (2.2 m2/g). The larger specific surface area possibly led to the increase of contacts with electron conductive additives (carbon) and electrolytes.
Photocatalytic degradation of Basic Blue 41 dye under visible light over SrTiO3/Ag3PO4 hetero‐nanostructures
Authors: Kafian Soheila , Sadeghzadeh‐Attar Abbas 
Published: August 2022

AbstractIn an attempt to develop nanostructured photocatalysts with high performance, SrTiO3/Ag3PO4 hetero‐nanostructures were successfully fabricated. The formed binary heterojunctions were composed of SrTiO3 nanotubes prepared using liquid‐phase deposition, and Ag3PO4 nanoparticles prepared using a sol–gel method. Synthesis details, including morphology, structure, and optical properties of the prepared photocatalysts, were characterized and comparatively discussed. The results showed that at an optimal ratio of SrTiO3 to Ag3PO4 (20–80), the photocatalytic degradation of Basic Blue 41 under 80‐min visible light irradiation is the maximum amount of 99%, which is about 4.4 and 1.5 times higher than that of pristine SrTiO3 nanorods and Ag3PO4 nanoparticles, respectively. It can be due to the synergistic effect of two materials that provide high light absorption and charge carriers’ separation. Finally, a detailed possible mechanism for enhancing the photocatalytic activity of the SrTiO3/Ag3PO4 hetero‐nanostructures was proposed.

Published: August 2022

AbstractSiFeCO ceramic nanocomposites with porous structure have been successfully prepared via pyrolysis of novel iron‐containing precursors, which were synthesized by modification of polycarbosilane with different contents of MIL‐101(Fe), a kind of metal‐organic framework made by our laboratory. Iron‐containing precursors were pyrolyzed at relatively low temperatures ranging from 500 to 900°C under nitrogen atmosphere, the polymer‐to‐ceramic conversion process were investigated by Fourier transform infrared spectroscopy, X‐ray diffraction (XRD), and thermo gravimetric analysis (TGA) measurements. SiFeCO ceramics with different iron contents were intensively studied with respect to their crystallization behavior, microstructure evolution, and porous morphology influenced by additive amount of MIL‐101(Fe). The results of XRD and Transmission electron microscopy revealed that MIL‐101(Fe)‐modified precursors converted into amorphous SiFeCO ceramics when pyrolyzed below 700°C under nitrogen, extremely small Fe3O4 and α‐Fe crystallites with grain size of only 2–5 nm were in situ generated and dispersed uniformly in the SiCO ceramic matrix. Simultaneously, interconnected porous structure was created in the matrix by the decomposition of MIL‐101(Fe). The as‐obtained SiFeCO ceramics could serve as heterogeneous Fenton‐like catalysts for the degradation of xylene orange and exhibit outstanding catalytic properties.

AbstractBackgroundCorticosteroids remain the main therapy in erythema nodosum leprosum (ENL), and long‐term usage in chronic or recurrent ENL is a cause of significant morbidity and mortality. Thalidomide exerts dramatic effect in controlling ENL and helps reduce the dose of steroids, but the cost is a hindrance to its usage.MethodsPatients of ENL (steroid naïve and steroid‐dependent) were recruited over a 1‐year period. An escalating dose of low‐dose thalidomide with a reducing dose of prednisolone was titrated depending on the control of disease activity. The primary aim was to reduce the dose of steroids to the lowest effective dose, and the secondary aim was to stop.ResultsSixteen patients of ENL were studied (mean duration of ENL 22.1 months, 15 severe ENL), and a majority (11/16, 68%) were on steroids with a mean duration of 11.27 months. All patients had steroid‐related side effects (cushingoid habitus 81.8%, weight gain 54.5%, diabetes mellitus 9%, hyperlipidemia 18.18%, cataract 18.1%, osteoporosis 36.3%, striae 36.3%, acneiform eruptions 18.1%, and myopathy 9%). Steroids could be tapered in a majority of patients (n = 9) within 3 months (mean 2.44 months) with a low dose of thalidomide (25–150 mg/day, mean 78.3 mg) achieving a significant reduction in prednisolone dose (33.16 mg at baseline; 4.28 mg at 3 months, P < 0.05). Steroids could be stopped in 92% of patients by 3.03 months, and both drugs could be stopped in 80% of cases by 5.83 months.ConclusionThe rapid and effective control of ENL with low‐dose thalidomide in our series is comparable to the historical efficacy of high‐dose thalidomide regimens, making it an affordable therapy in resource‐constrained settings and an excellent steroid‐sparing agent. The rapid onset of disease control is likely attributable to its action via neutrophils.
Accommodation, empowerment and disinvestment—Typical second‐language learning trajectories of Syrian refugees in Germany
Authors: Bernhard Stefan 
Published: August 2022

AbstractThis paper asks how refugees' second‐language learning processes are embedded in their lives in host countries. To address this question, the paper proposes the concept of second‐language learning trajectories. These trajectories explain refugees' second‐language learning as closely intertwined with learners' self‐understanding, experiences and positioning in host countries. Using longitudinal narrative interview data from Syrian refugees in Germany, the paper identifies three different types of second‐language learning trajectories, that is empowerment, accommodation and disinvestment. These trajectories have vastly diverse outcomes, not only in terms of second‐language proficiency but also in terms of learning motivation, self‐views and future prospects. Moreover, second‐language learning trajectories evolve based on self‐reinforcing dynamics that make switching between trajectories increasingly difficult over time. This is particularly detrimental to refugees on the disinvestment trajectory, which entails social decline and exclusion. The paper also identifies institutional regulations in Germany that compound refugees' struggles to gain a foothold in their host country.
