Examining family processes linked to adolescent problem behaviors in single-mother families: The moderating role of school connectedness
Authors: Lee Woon Kyung , Joo Young Sun 
Published: September 2022

ObjectivePrevious research has shown that adolescents in single-mother households are at heightened risk for adjustment problems. However, limited studies have investigated the mechanisms leading to adolescent problem behaviors in single-mother households. To address this research gap, this study applied the Family Stress Model to examine how single mothers’ material hardship is linked to adolescent problem behaviors, focusing on the mediating roles of mothers’ depression and mother-adolescent closeness. The moderating role of adolescent school connectedness in the relationships between mother-adolescent closeness and school connectedness and between mothers’ depression and school connectedness was also investigated.Materials and methodsThe study analyzed data from 1,384 adolescents and their single mothers who participated in the Fragile Families and Child Wellbeing Study at Wave 6. The associations between study variables were analyzed using structural equation modeling by decomposing the direct, indirect, and total effects of material hardship on adolescent problem behaviors. School connectedness’s interactions with mother-adolescent closeness and mothers’ depression were also examined.ResultsResults showed a significant indirect relationship between material hardship and adolescent problem behaviors through sequential mediation of mothers’ depression and mother-adolescent closeness. Mothers’ depression also significantly mediated the relationship between material hardship and problem behaviors. Lastly, school connectedness moderated the relationship between mother-adolescent closeness and adolescents’ internalizing behaviors. The association between mother-adolescent closeness and adolescents’ internalizing behavior was weaker for adolescents with higher levels of school connectedness.ConclusionThe results indicate the important indirect effect of economic strain on adolescents’ problems behaviors in single-mother households, which has been less emphasized compared to the effects in earlier childhood. High rates of material hardship and adolescent problem behaviors in single-mother families call for multifaceted interventions focusing on family processes and protective factors, including school environment.
Gender and intersecting vulnerabilities on the mental health unit: Rethinking the dilemma
Authors: Morton Elizabeth Kathleen , McKenzie Sarah K. , Cooper Amy , Every-Palmer Susanna , Jenkin Gabrielle Lisa Simone 
Published: September 2022

BackgroundGender is routinely pitched as a key determinant of vulnerability for staff and residents on acute mental health inpatient units. Since the 1960's mixed gender units have become more prominent in Western health systems, yet questions remain around the configuration of these units, including how to ensure emotional and physical safety of those living and working in them.MethodsThis paper draws on a large study of the lived experiences of 42 staff and 43 service users from different acute mental health units in New Zealand. We conducted thematic analysis of interview data from four units with diverse architectural layouts to identify key themes central to decisions around gender and spatial design.ResultsKey themes emerged around gender-related trauma histories, safety perceptions and vulnerabilities, accommodation of gender-diverse and non-binary mental health service users, and gender-specific needs and differences. A further theme, of it goes beyond gender emphasized that there are many other non-gender attributes that influence vulnerability on the unit.ConclusionsWhile findings emphasize the need for safe places for vulnerable people, trauma-informed care, access to staff who “understand,” and recreation that is meaningful to the individual, we question if the dilemma of gender-separation vs. gender-mixing is an outmoded design consideration. Instead, we argue that a flexible, person-centered approach to provision of care, which values autonomy, privacy, and safety as defined by each service user, and that promotes choice-making, obviates a model where gender accommodations are fore. We found that a gender-exclusive narrative of vulnerability understates the role of other identifiers in dynamics of risk and vulnerability, including age, physicality, past violence, trauma history, mental unwellness, and substance use. We conclude gender need not be a central factor in decisions around design of prospective built unit environments or in occupational and clinical decisions. Instead, we suggest flexible spatial layouts that accommodate multiple vulnerabilities.

Authors: Hoeberg Emma , Haga Henning Andreas , Lervik Andreas 
Published: September 2022

ObjectivesTo investigate whether morphine causes a change in mean arterial blood pressure (MAP) heart rate (HR) and oxygen extraction (OE) rate in healthy horses anesthetized with isoflurane and a dexmedetomidine infusion.Material and methodsThe study design was prospective clinical, randomized, blinded two groups including 33 horses. All horses were sedated with romifidine IV, and anesthesia was induced with midazolam IV and ketamine IV and maintained with isoflurane in oxygen and medical air and a dexmedetomidine infusion. As a baseline venous and arterial blood, HR and MAP were sampled. Thereafter either morphine 0.1 mg kg−1 IV or an equivalent volume of NaCl 0.9% IV was administered. HR and MAP were then further sampled for 5 min before venous and arterial blood was again sampled. OE was calculated based upon arterial and venous blood gas analysis. To evaluate the change in minimum MAP, mean HR, and OE, the differences between baseline and observation period values were further termed delta MAP, delta HR, and delta OE. Individual delta MAPs were normalized to the minimum baseline value and are reported as a percentage. Alpha was set to 0.05. Confidence intervals 95% (CI) were calculated for delta MAP, delta HR, and delta OE within groups, and for the difference between groups.ResultsThe 95% CIs for delta MAP (%), delta HR (min−1), and delta OE (mL/dL) in the morphine group were −20.5 to −9.0, 0.6 to 3.1, and −0.1 to 0.6 and in the placebo group were −17.4 to −10.1, 0.2 to 2.0, and −0.2 to 0.3, respectively. The 95% CI for the differences in delta MAP (%), delta HR (min−1), and delta OE (mL/dL) were −5.5 to 7.6, −2.3 to 0.7, and −0.7 to 0.2, respectively. The minimum MAP of one horse in the morphine group decreased around 50% between baseline and observation period with almost unchanged OE and HR.Conclusion and clinical relevanceThe effects of morphine 0.1 mg kg−1 IV on HR, MAP, and OE in healthy horses anesthetized with isoflurane and a CRI of dexmedetomidine are minimal.

Published: September 2022

A novel output-capacitorless low-dropout regulator (OCL-LDO) with an embedded slew-rate-enhancement (SRE) circuit is presented in this paper. The SRE circuit adopts a transient current-boost strategy to improve the slew rate at the gate of the power transistor when a large voltage spike at the output is detected. In addition, a feed-forward transconductance cell is introduced to form a push–pull output structure with the power transistor. The simulation results show that the maximum transient output voltage variation is 23.5 mV when the load current ILOAD is stepped from 0 to 100 mA in 100 ns with a load capacitance of 100 pF, and the settling time is 1.2 μs. The proposed OCL-LDO consumes a quiescent current of 30 μA and has a dropout voltage of 200 mV for the maximum output current of 100 mA.

Today, the development of nanomaterials with sensing properties attracts much scientific interest because of the demand for low-cost nontoxic colloidal nanoprobes with high sensitivity and selectivity for various biomedical and environment-related applications. Carbon dots (CDs) are promising candidates for these applications as they demonstrate unique optical properties with intense emissions, biocompatibility, and ease of fabrication. Herein, we developed synthesis protocols to obtain CDs based on o-phenylenediamine with a variety of optical responses depending on additional precursors and changes in the reaction media. The obtained CDs are N-doped (N,S-doped in case of thiourea addition) less than 10 nm spherical particles with emissions observed in the 300–600 nm spectral region depending on their chemical composition. These CDs may act simultaneously as absorptive/fluorescent sensing probes for solvent polarity with ∆S/∆ENT up to 85, for ∆ENT from 0.099 to 1.0 and for pH values in the range of 3.0–8.0, thus opening an opportunity to check the pH in non-pure water or a mixture of solvents. Moreover, CDs preserve their optical properties when embedded in cellulose strips that can be used as sensing probes for fast and easy pH checks. We believe that the resulting dual-purpose sensing nano probes based on CDs will have high demand in various sensing applications.

Recent progress of organic scintillators
Authors: Koshimizu Masanori 
Published: September 2022

Abstract
Recent development of organic scintillators is reviewed from the viewpoint of materials science. Design and crystal growth of organic crystalline scintillators, use of novel solvents and solutes in liquid scintillators, and development of plastic scintillators based on novel polymer hosts or novel fluorescent molecules are introduced. Additionally, development of loaded liquid or plastic scintillators is reviewed on the basis of two approaches of loading: molecules or nanoparticles. A disadvantage of organic scintillators has been their low scintillation light yields. Hence, materials design for improving scintillation light yields is introduced in detail with description on related excited state dynamics. Finally, future prospect for the improvement of scintillation light yield is briefly given.

Published: September 2022

Abstract
Transparent ceramics have attracted attention as a new optical material that can replace glasses and single crystals. In this study, we investigated the application of transparent ceramics as dosimeter materials. Specifically, thermally stimulated luminescence (TSL) properties of MgO, Al2O3, and CaF2: Mn transparent ceramics were evaluated in comparison with those of single crystals and opaque ceramics. As a result, transparent ceramics of three chemical compositions exhibited the highest TSL intensity.
Selective damping modulation in a synthetic antiferromagnet induced by spin–orbit torque

Published: September 2022

Abstract
Magnetization dynamics in a synthetic antiferromagnet with an adjacent Pt layer are investigated. Using dc bias, magnetic damping can be effectively controlled by the spin–orbit torque from the Pt layer. In the spin-flop state, the acoustic mode is modulated by the dc bias, but the optical mode is not sufficiently modulated. In the saturation state, the optical mode is effectively modulated. By appropriately selecting acoustic and optical modes and magnetization states such as the spin-flop and saturation states, modulation of the mutual phases of the ac spin currents driven by the ac damping torques can be realized.

Published: September 2022

La emergencia sanitaria generada por el SARS-CoV2, ha impactado de diferentes maneras en las dinámicas de la educación superior, desde el cierre generalizado, la toma de medidas sanitarias, el distanciamiento social y como consecuencia la suspensión de actividades presenciales como medida para evitar su propagación. La implementación de las Tecnologías de la Información y la Comunicación (TIC), se constituye un desafío que enfrentan docentes y estudiantes por las características orográficas, de conectividad, falta de equipo de cómputo y preparación para el desarrollo de actividades académicas. En ese sentido es necesario conocer el contexto de los estudiantes con respecto al equipamiento y la conectividad para valorar el estado que guardan sus capacidades educativas, ya que, no todos los estudiantes cuentan con las mejores condiciones para continuar con su proceso educativo evidenciando la brecha digital que existe. Este trabajo hace referencia particularmente al Centro Universitario del Norte de la Universidad de Guadalajara, donde se analizó la problemática de los estudiantes ante la pandemia de COVID-19, relacionada con el acceso y la disponibilidad a las TIC.
El diseño de la investigación es de corte cuantitativo descriptivo, se encontró que la falta de acceso a las TIC en la zona Norte de Jalisco y sur de Zacatecas sobre todo en términos de accesibilidad y habilidades ocurre en las personas que se encuentran en un estrato socioeconómico bajo y aquellas que viven en comunidades rurales, siendo los más vulnerables los estudiantes indígenas.

First Detection of Transverse Vertical Oscillation during the Expansion of Coronal Loops

Published: September 2022

Abstract
In this Letter, we perform a detailed analysis of the M5.5 class eruptive flare occurring in active region 12,929 on 2022 January 20. The eruption of a hot channel generates a fast coronal mass ejection (CME) and a dome-shaped extreme-ultraviolet (EUV) wave at speeds of 740–860 km s−1. The CME is associated with a type II radio burst, implying that the EUV wave is a fast-mode shock wave. During the impulsive phase, the flare shows quasi-periodic pulsations (QPPs) in EUV, hard X-ray, and radio wavelengths. The periods of QPPs range from 18 to 113 s, indicating that flare energy is released and nonthermal electrons are accelerated intermittently with multiple timescales. The interaction between the EUV wave and low-lying adjacent coronal loops (ACLs) results in contraction, expansion, and transverse vertical oscillation of ACLs. The speed of contraction in 171, 193, and 211 Å is higher than that in 304 Å. The periods of oscillation are 253 s and 275 s in 304 Å and 171 Å, respectively. A new scenario is proposed to explain the interaction. The equation that interprets the contraction and oscillation of the overlying coronal loops above a flare core can also interpret the expansion and oscillation of ACLs, suggesting that the two phenomena are the same in essence.

Abstract
The Moon is significantly depleted in volatile elements when compared to Earth, an observation that has resulted in various formation scenarios leading to the loss of volatiles. Sodium is a moderately volatile element that is a lithophile, which can be utilized as a tracer of the volatile history in planetary bodies. It is also well observed in the exosphere of several bodies in our solar system and exoplanetary systems. But lunar surface sodium abundances have so far been measured only in samples brought back to Earth. We report on results from the first effort to provide a global-scale measurement of sodium on the lunar surface using X-ray fluorescent spectra from Chandrayaan-2. A global average of 1.33 ± 0.03 wt% derived here is higher than previously known. Trends in the sodium abundance indicate a long-lived adsorbate component that could explain the higher abundances reported here, which would act as a reservoir that sustains the lunar sodium exosphere.
Étudier des parlements sous contrainte
Authors: Duchesne Franck , Tardits Nicolas 
Published: September 2022

L’introduction de ce numéro permet de réfléchir à la relation improbable entre « Parlement » et « autoritarisme ». Dans ces contextes, les Parlements sont considérés comme peu dignes d’intérêt car sans pouvoir ou trop assujettis à un exécutif omnipotent. à l’aide du concept de domination, la place des Parlements dans ces configurations prend un nouveau sens : ni soumis ni libres, ces institutions et leurs agents participent à leur façon à l’ordre politique de ces états.
L’injonction à la « pédagogie du supérieur » : un cadrage étroit des enseignants-chercheurs ?
Authors: Tralongo Stéphanie , Noûs Camille 
Published: September 2022

Présentée comme une solution au « problème » de l’université par les pouvoirs publics, la thématique de la « pédagogie du supérieur » porte depuis une vingtaine d’années un appel à un changement radical des pratiques. Par son adhésion à une vision néolibérale de la société qu’instrumente le nouveau management public, elle constitue une boîte à outils discursive, cognitive et pratique. L’intention est ici de résister à l’injonction de bâtir une réflexion visant à dire comment changer, pour se demander pourquoi et par quels moyens l’attente de transformations est aussi vive et orchestrée.
Recherches en éducation et science ouverte : un oxymore inattendu ?
Authors: Bruillard Éric 
Published: September 2022

Si la notion de science ouverte est fortement portée et sa pratique peut conduire à des améliorations importantes, les multiples discours qui s’y rapportent ne sont pas sans contradictions ni zones d’ombre. Derrière l’idée d’une science « plus transparente, plus rapide et d’accès universel » risque de se développer une conception étroite et réductrice autour de la preuve et du contrôle, incluant la nécessité de reproductibilité ou de réplicabilité, en tension avec des visions plus ouvertes et participatives des recherches en éducation.
2022, la présidentielle des « blocs » ?
Authors: Le Digol Christophe 
Published: September 2022

À l’occasion de l’élection présidentielle de 2022, une interprétation politique semble dominer les échanges entre élus et experts du commentaire politique : l’opposition de « blocs » politiques. Loin d’être une catégorie inventée et diffusée pour l’occasion, cette catégorie est le résultat d’un travail éminemment symbolique de production et de diffusion de catégories, dont la fonction consiste notamment à se substituer au clivage gauche-droite, apparemment moins pertinent pour interpréter les enjeux politiques depuis 2017.
