AbstractGravel beaches in the Mediterranean ecoregion represent an economically important and unique habitat type. Yet, burgeoning tourism, intensive coastal development and artificial nourishment of beaches may jeopardize their ecological communities. To date, species that reside on gravel beaches and the consequences of beach alterations are poorly understood, which hampers the development of a sustainable coastal tourism industry along the region's shorelines. Using a simple collection method based on dredging buckets through the intertidal section of beaches, we quantified the microhabitat association of two sympatric clingfish species in the genus Gouania at seven natural and an artificial gravel beach based on sediment characteristics. We hypothesized that slender (G. pigra) and stout (G. adriatica) morphotypes would partition interstitial niche space based on sediment size, which may affect the vulnerability of the species to changes in gravel beach composition due to coastal development. We detected substantial differences in gravel composition within and among the sampled beaches which suggests scope for microhabitat partitioning in Gouania. Indeed, we found significant relationships between species identity and the presence/absence and abundance of individuals in hauls based on their positioning on PC1. Our results suggest that modifications of gravel beaches through coastal development, including beach nourishment, intensifying coastal erosion, or artificial beach creation, may have detrimental consequences for the two species if sediment types or sizes are altered. We posit that, given the simplicity and efficacy of our sampling method and the sensitivity of Gouania species to prevailing gravel composition, the genus could serve as an important indicator for gravel beach management in the Mediterranean ecoregion.
BioLake: A first assessment of lake temperature‐derived bioclimatic predictors for aquatic invasive species

AbstractAquatic invasive species (AIS) present major ecological and economic challenges globally, endangering ecosystems and human livelihoods. Managers and policy makers thus need tools to predict invasion risk and prioritize species and areas of concern, and they often use native range climate matching to determine whether a species could persist in a new location. However, climate matching for AIS often relies on air temperature rather than water temperature due to a lack of global water temperature data layers, and predictive power of models is seldom evaluated. We developed 12 global lake (water) temperature‐derived “BioLake” bioclimatic layers for distribution modeling of aquatic species and compared “climatch” climate matching predictions (from climatchR package) from BioLake with those based on BioClim temperature layers and with a null model. We did this for 73 established AIS in the United States, training the models on their ranges outside of the United States and Canada. Models using either set of climate layers outperformed the null expectation by a similar (but modest) amount on average, but some species were occasionally found in locations with low climatch scores. Mean US climatch scores were higher for most species when using air temperature. Including additional climate layers in models reduced mean climatch scores, indicating that commonly used climatch score thresholds are not absolute but can be context specific and may require calibration based upon climate data used. Although finer resolution global lake temperature data would likely improve predictions, our BioLake layers provide a starting point for aquatic species distribution modeling. Climate matching was most effective for some species that originated at low latitudes or had small ranges. Climatch scores remain useful but limited for predicting AIS risk, perhaps because current ranges seldom fully reflect climatic tolerances (fundamental niches). Managers could consider climate matching as one of a suite of tools that can be used in AIS prioritization.
C−S Cross‐Coupling of Aryldiazonium Salts with Thiols Mediated by Gold
Authors: Caballero‐Muñoz Alejandra , Rosas‐Ortega Miguel , Díaz‐Salazar Howard , Porcel Susana 
Published: July 2023

AbstractIn this work, the coupling of aryldiazonium salts with thiols mediated by the readily accessible gold complex Me2SAuCl is described. In the reported protocol, the addition of 2,2′‐bipyridine as a ligand leads to higher yields than phosphines. The reaction proceeds at room temperature under soft mildconditions and has a broad scope in both the aryldiazonium salt and the thiol. Notably, the coupling works with aryldiazonium salts containing two additional substituents.

AbstractHere described an acid‐controlled regional diverse synthesized process of CF3‐containing ketoimines by the condensation of benzo[b]thiophene‐2,3‐dione and 2,2,2‐trifluoroethlamine. The imines obtained at either the 2‐position or 3‐position can be further used as substrates in asymmetric organocatalyzed [3+2]‐cycloaddition reactions, leading to a library of regiodiverse bispiro‐compounds with 85–96 % yield and 65–99 % ee.
The excluded ordinary? A theory of populist radical right supporters’ position in society
Authors: Versteegen Peter Luca 
Published: July 2023

AbstractPopulist Radical Right (PRR) supporters see themselves as ordinary people, represent a broad societal spectrum, and overrepresent historically powerful majorities (e.g., whites, men). Simultaneously, members of these groups increasingly feel neglected or discriminated against. In article, I argue that some PRR supporters may feel excluded from society despite seeing themselves as ordinary people. Optimal Distinctiveness Theory posits that individuals must balance their countervailing needs to belong to the larger group while feeling recognized as unique subgroup members. While PRR supporters’ self‐perception as ordinary people suggests that they experience belonging to the larger society, subjective experiences of neglect and disrespect may leave their uniqueness need unsatisfied. I showcase this argument using semi‐structured interviews with German PRR supporters. I discuss avenues for future quantitative tests and raise a significant implication: if subjective lack of subgroup uniqueness contributes to PRR support, reminding majority members of their objective subgroup recognition could mitigate it.

AbstractDielectrophoresis (DEP) is a successful method to recover nanoparticles from different types of fluid. The DEP force acting on these particles is created by an electrode microarray that produces a nonuniform electric field. To apply DEP to a highly conducting biological fluid, a protective hydrogel coating over the metal electrodes is required to create a barrier between the electrode and the fluid. This protects the electrodes, reduces the electrolysis of water, and allows the electric field to penetrate into the fluid sample. We observed that the protective hydrogel layer can separate from the electrode and form a closed domed structure and that collection of 100 nm polystyrene beads increased when this occurred. To better understand this collection increase, we used COMSOL Multiphysics software to model the electric field in the presence of the dome filled with different materials ranging from low‐conducting gas to high conducting phosphate‐buffered saline fluids. The results suggest that as the electrical conductivity of the material inside the dome is reduced, the whole dome acts as an insulator which increases electric field intensity at the electrode edge. This increased intensity widens the high‐intensity electric field factor zone resulting in increased collection. This informs how dome formation results in increased particle collection and provides insight into how the electric field can be intensified to the increase collection of particles. These results have important applications for increasing the recovery of biologically‐derived nanoparticles from undiluted physiological fluids that have high conductance, including the collection of cancer‐derived extracellular vesicles from plasma for liquid biopsy applications.
Framing the benefits of European Union policy expansion on energy efficiency of buildings: A Swiss knife or a Trojan horse
Authors: von Malmborg Fredrik , Björklund Martin , Nordensvärd Johan 
Published: July 2023

AbstractThis paper analyzes through qualitative and quantitative analysis of European Union (EU) policy documents the framing of EU policy on energy‐efficient buildings from the 1970s to 2022. We find that it has been framed in different ways over the decades and the framing has expanded to include more and more benefits. Through this expansion, energy efficiency has been linked to other policy areas, such as security, environmental, economic, and social policy. The shifts in framing can be seen as responses to external events. The expansion can also be explained using two metaphors to analyze how the framing differs depending on political positioning. One where policy is seen as a Swiss knife, able to solve multiple political problems, and one where policy is seen as a Trojan horse, where new policy domains are snuck in by policymakers disguising it as energy efficiency policy to increase EU competency in relation to national governments.
Option pricing with overnight and intraday volatility
Authors: Liang Fang , Du Lingshan , Huang Zhuo 
Published: July 2023

AbstractEfficiently exploiting the volatility information contained in price variations is important for pricing options and other derivatives. In this study, we develop a new and flexible option‐pricing model that explicitly specifies the joint dynamics of overnight and intraday returns. The application of multivariate Edgeworth–Sargan density enables us to derive analytical approximations for option valuation formulas. Empirically, the model improves significantly upon benchmark models using S&P 500 index options. In particular, its separate modeling of intraday and overnight return volatility leads to an out‐of‐sample gain of 7.24% in pricing accuracy compared with the modeling of the close‐to‐close return volatility as a whole. The improvements are more pronounced during highly volatile periods.
Spanking and parental verbal aggression during early childhood: Association with later academic achievement and the mediating role of executive function

Published: July 2023

AbstractSpanking and parental verbal aggression are potentially toxic stressors that can negatively affect children's academic achievement by disrupting mental skills like executive function. Yet little empirical evidence has been provided for this mediating pathway. This study used data from the Early Childhood Longitudinal Study Kindergarten Cohort of 2010–2011 (n = 11,421) to examine the associations between early childhood exposure to spanking and parental verbal aggression and subsequent academic achievement. We also investigated the mechanism for these associations by exploring the mediating role of executive function within those associations. Findings revealed that spanking and parental verbal aggression in kindergarten and first grade were negatively associated with reading and math scores in fifth grade, controlling for demographics and initial academic performance. Executive function (i.e., inhibitory control, cognitive flexibility and working memory) accounted for more than half (50%–57%) and more than one fourth (24%–31%) of the total effects of spanking and verbal aggression on academic achievement, respectively. Findings provide important evidence for early intervention programs aiming to promote children's academic achievement and executive function by interfering or preventing harsh discipline.Highlights
We examined the pathway from spanking and verbal aggression in early childhood to academic achievement in later school years through executive function.
Path analysis results show executive function was a significant mediator in the negative associations between academic achievement in fifth grade and early exposure to spanking and aggression.
Besides avoiding harsh parenting, intervention programs to support child academic achievement could also target promoting executive function development.
Gender equitable attitudes as a significant mediator of bystander intentions among sexual minority adolescents

Published: July 2023

AbstractIntroductionBystander intervention is a promising approach for prevention of sexual violence. Assessing factors that may promote or hinder bystander intervention among sexual minority adolescents (i.e., lesbian, gay, bisexual, queer) is essential, given high rates of violence among sexual minority youth. Prior research examining barriers and facilitators of bystander intervention intentions does not consider how factors may vary by sexual identity. As such, the current study aimed to (1) examine how barriers and facilitators of bystander intentions, bystander intentions, and bystander behavior vary between heterosexual and sexual minority high school adolescents and (2) explore mediators of the association between sexual identity and bystander intervention intentions. We proposed that students’ level of school connectedness, gender equitable attitudes, and anticipated positive consequences of bystander intervention (e.g., having a moral desire to help) would promote bystander intervention intentions, whereas binge drinking, and students anticipated negative consequences of bystander intervention (e.g., fear for one's own safety) would tend to weaken bystander intervention intentions.MethodsParticipants included 2,645 10th grade students (Mage = 15.37, SD = 0.61) recruited from high schools in the Northeast United States.ResultsSexual minority youth reported higher bystander intentions, bystander behavior, anticipated positive consequences of bystander intervention, gender equitable attitudes, and binge drinking relative to heterosexual youth. Sexual minority youth had lower school connectedness than heterosexual youth. Anticipated negative consequences of bystander intervention did not vary by group. Parallel linear regression analyses found that only anticipated positive consequences of bystander intervention and gender equitable attitudes fully mediated the relationships between sexual identity and bystander intentions.ConclusionsBystander intervention programs may benefit from attending to specific facilitators of bystander intervention among sexual minority youth, such as gender equitable attitudes.

Published: July 2023

AbstractWe engaged in this study to better understand how counselors cope with and process client suicide. A researcher who also experienced a client suicide conducted interviews with licensed professional counselors (N = 7). Using interpretive phenomenological analysis, we identified eight superordinate themes: (a) professional counseling culture, (b) intense emotional reaction, (c) processing loss, (d) supports, (e) barriers, (f) impairment, (g) disillusionment, and (h) finding meaning. Findings have implications for the counseling profession, counselor educators, agencies and supervisors, counselors, and counselors‐in‐training.
Analytical quadrature method using recurrence formulas for two‐electron integrals of frequency‐dependent Breit interaction
Authors: Inoue Nobuki , Nakajima Takahito 
Published: July 2023

AbstractA recursive scheme was proposed to calculate two‐electron integrals of frequency‐dependent Breit interactions in electronic structure calculations using Gaussian basis functions. As shown in a previous study [R. Ahlrichs, Phys. Chem. Chem. Phys. 8 (2006) 3072–3077], the vertical recurrence relation for the two‐electron integrals of the general two‐body potential is valid. In addition, the authors have shown that the horizontal case is also valid. Explicit expressions for generalized molecular incomplete gamma function corresponding to the frequency‐dependent Gaunt and gauge potentials were then derived, along with their asymptotic formulas. In addition, an implementation for computing the generalized molecular incomplete gamma function was proposed. Through numerical calculations, the shape of the curves of the generalized molecular incomplete gamma functions were found to vary significantly from that of the zero‐energy case with the increase in the energy variable.
Characterizing suicidal ideation, suicidal behaviors, and service utilization among unhoused individuals using a health information exchange

Published: July 2023

AbstractIntroductionUnhoused individuals have high rates of suicidal ideation (SI) and suicidal behaviors (SB), but few have studied the relative timing of homelessness and SI/SB. Our study examines the potential to use state‐wide electronic health record data from Rhode Island's health information exchange (HIE) to identify temporal relationships, service utilization, and associations of SI/SB among unhoused individuals.MethodsWe use timestamped HIE data for 5368 unhoused patients to analyze service utilization and the relative timing of homelessness versus SI/SB onset. Multivariable models identified associations of SI/SB, hospitalization, and repeat acute care utilization within 30 days from clinical features representing 10,000+ diagnoses captured within the HIE.ResultsThe onset of SI typically precedes homelessness onset, while the onset of SB typically follows. Weekly rates of suicide‐related service utilization increased over 25 times the baseline rate during the week before and after homelessness onset. Over 50% of encounters involving SI/SB result in hospitalization. Of those engaging in acute care for suicide‐related reasons, we found high rates of repeat acute care encounters.ConclusionHIEs are a particularly valuable resource for understudied populations. Our study demonstrates how longitudinal, multi‐institutional data from an HIE can be used to characterize temporal associations, service utilization, and clinical associations of SI and behaviors among a vulnerable population at scale. Increasing access to services that address co‐occurring SI/SB, mental health, and substance use is needed.

AbstractBacterial extracellular vesicles (BEVs) are increasingly seen as key signalling mediators between the gut microbiota and the host. Recent studies have provided evidence of BEVs ability to transmigrate across cellular barriers to elicit responses in other tissues, such as the central nervous system (CNS). Here we use a combination of single‐, two‐ and three‐cell culture systems to demonstrate the transmigration of Bacteroides thetaiotaomicron derived BEVs (Bt‐BEVs) across gut epithelium and blood brain barrier (BBB) endothelium, and their subsequent acquisition and downstream effects in neuronal cells. Bt‐BEVs were shown to traffic to the CNS in vivo after intravenous administration to mice, and in multi‐cell in vitro culture systems to transmigrate across gut epithelial and BBB endothelial cell barriers, where they were acquired by both microglia and immature neuronal cells. No significant activation/inflammatory effects were induced in non‐differentiated neurons, in contrast to that observed in microglia cells, although this was notably less than that induced by lipopolysaccharide (LPS). Overall, our findings provide evidence for transmigration of Bt‐BEVs across gut‐epithelial and BBB endothelial cell barriers in vivo and in vitro, and their downstream responses in neural cells. This study sheds light onto how commensal bacteria‐derived BEV transport across the gut‐brain axis and can be exploited for the development of targeted drug delivery.

AbstractAssessment of minimal residual disease in acute lymphoblastic leukemia by immune repertoire NGS requires spiking CDR3 sequences at known quantities into the patient's sample. Recently, the EuroClonality‐NGS group released one of the most comprehensive protocols for this purpose. ARResT/Interrogate is a closed‐source software for processing these NGS libraries, developed by this same group. Vidjil, an open‐source alternative, currently cannot handle libraries prepared using this protocol. Here, we present a Vidjil add‐on to solve this issue. EuroClonality‐NGS prepared samples analyzed with Vidjil and ARResT/Interrogate were highly concordant (r = 0.998) and presented low error (root‐mean‐square error, RMSE = 0.112).
