The pre-axial border medially moves between the fetal and early postnatal periods, and the foot sole can be placed on the ground. Nonetheless, the precise timeline when this posture is achieved remains poorly understood. The hip joint is the most freely movable joint in the lower limbs and largely determines the lower-limb posture. The present study aimed to establish a timeline of lower-limb development using a precise measurement of femoral posture. Magnetic resonance images of 157 human embryonic samples (Carnegie stages [CS] 19–23) and 18 fetal samples (crown rump length: 37.2–225 mm) from the Kyoto Collection were obtained. Three-dimensional coordinates of eight selected landmarks in the lower limbs and pelvis were used to calculate the femoral posture. Hip flexion was approximately 14° at CS19 and gradually increased to approximately 65° at CS23; the flexion angle ranged from 90° to 120° during the fetal period. Hip joint abduction was approximately 78° at CS19 and gradually decreased to approximately 27° at CS23; the average angle was approximately 13° during the fetal period. Lateral rotation was greater than 90° at CS19 and CS21 and decreased to approximately 65° at CS23; the average angle was approximately 43° during the fetal period. During the embryonic period, three posture parameters (namely, flexion, abduction, and lateral rotation of the hip) were linearly correlated with each other, suggesting that the femoral posture at each stage was three-dimensionally constant and exhibited gradual and smooth change according to growth. During the fetal period, these parameters varied among individuals, with no obvious trend. Our study has merits in that lengths and angles were measured on anatomical landmarks of the skeletal system. Our obtained data may contribute to understanding development from anatomical aspects and provide valuable insights for clinical application.

Published: May 2023

This study examined how the Australian news media have portrayed public hospital Emergency Departments (EDs) over the last two decades. A systematic review and media frame analysis, searching Factiva and Australia and New Zealand News Stream for digital and print news articles published between January 2000 and January 2020. Eligibility criteria were (1) discussed EDs in public hospitals; (2) the primary focus of the article was the ED; (3) focused on the Australian context; (4) were published by one of the Australian state-based news outlets (e.g., The Sydney Morning Herald, Herald Sun). A pair of reviewers independently screened 242 articles for inclusion according to the pre-established criteria. Discrepancies were resolved via discussion. 126 articles met the inclusion criteria. Pairs of independent reviewers identified frames in 20% of the articles using an inductive approach to develop a framework for coding the remaining articles. News media rely heavily on reporting problems within and with the ED, while also proposing a cause. Praise for EDs was minimal. Opinions were primarily from government spokespeople, professional associations, and doctors. ED performance was often reported as fact, with no reference to the source of the information. Rhetorical framing devices, such as hyperbole and imagery, were used to emphasise dominant themes. The negative bias inherent in news media reporting of EDs could potentially damage public awareness of ED functioning, with implications for the likelihood of the public’s accessing ED services. Like in the film Groundhog Day, news media reporting is stuck in a loop reporting the same narrative over and over again.
Parents of children with hearing loss: Impact and exposure of COVID-19 on mental health
Authors: Cejas Ivette , Sanchez Chrisanda , Holcomb Meredith , Coto Jennifer
Published: May 2023

The aim of this study was to evaluate the impact and exposure of COVID-19 on parent mental health (e.g., depression, anxiety, and post-traumatic stress disorder (PTSD), for parents of children with hearing loss. The survey was distributed via an electronic survey to families subscribed to a pediatric program listserv as part of a university medical center. Fifty-five percent of parents reported elevated symptoms of anxiety, while 16% scored in the clinically significant range for depression. In addition, 20% of parents reported elevated symptoms of PTSD. Liner regressions found that impact of COVID-19 predicted anxiety symptoms, while both impact and exposure predicted depression and PTSD symptoms. In addition, both impact and exposure predicted COVID related parental distress. Exposure and impact of COVID-19 has had negative consequences on parents of children with hearing loss. Although exposure influenced parental mental health, impact uniquely affected depression and PTSD. Results highlight the need for mental health screening, as well implementation of psychological interventions using telehealth or in-person consultations. Future work should focus on post-pandemic challenges, including long-term psychological functioning due to the established relationship between parental mental health and pediatric outcomes.

Published: May 2023

Adolescence is a susceptible period to establish health-risk behaviors, which may have an impact on academic performance. The aim of this study was to investigate the association between health-risk behaviors (HRBs) and perceived academic performance (PAP) of adolescents in Shanghai, China. The data of the present study included three-round Shanghai Youth Health-risk Behavior Survey (SYHBS). This cross-sectional survey investigated multiple HRBs of students involved in dietary behaviors, physical activity and sedentary behaviors, intentional and unintentional injury behaviors, and substance abuse behaviors, as well as PAP by using self-reported questionnaire. Using a multistage random sampling method, 40,593 middle and high school students aged 12 to 18 years were involved. Only participants with complete data on HRBs information, academic performance and covariates were included. A total of 35,740 participants were involved in analysis. We used ordinal logistic regression to analyze the association between each HRB and PAP adjusting for sociodemographic, family environment and duration of extracurricular study. The results showed that students who did not eat breakfast or drink milk everyday were more likely to have a lower PAP, with a decreased odds of 0.89 (95%CI: 0.86–0.93, P<0.001) and 0.82 (95%CI: 0.79–0.85, P<0.001), respectively. The similar association was also found in students who did exercise ≥60 minutes for less than 5 days/week, spend time on watch TV beyond 3 hours/day and other sedentary behaviors. Most intentional and unintentional injuries, and ever smoked were associated with a lower PAP. Our finding suggests that multiple HRBs negatively associated with PAP of adolescents. It needs to raise public health concerns with HRBs in adolescents, and to develop and implement comprehensive interventions on HRBs.

Published: May 2023

Understanding how countries’ future development pathways could affect forests can help to avoid negative impacts and instead promote positive ones. Exploring this topic requires knowledge of which areas of the development agenda are likely to show the greatest progress, and how these expected changes relate to the drivers of deforestation and forest degradation that are currently affecting forests, or which may emerge as result of development-related changes. Based on this information, researchers, stakeholders and decisionmakers can engage in discussions to inform further research and interventions. We present an assessment framework that draws upon a range of data types to identify specific components of the development agenda that are likely to be of greatest relevance to forest conservation at the national level. We then assess the potential magnitude and likelihood of imminent changes in these areas over the short- to medium-term. We use this framework to assess 48 tropical countries, providing insights into the areas of sustainable development that are most likely to provide risks, opportunities or enabling conditions for forest conservation across much of the tropics. Our findings suggest that, across much of the tropics, ongoing risks to forests associated with agriculture, transport infrastructure and urban infrastructure could worsen, and that new risks from energy infrastructure could emerge. Opportunities relating to poverty reduction, tourism, and industry, among others, will require care to ensure that associated progress results in positive rather than negative forest impacts. Enabling conditions associated with, inter alia, improved education, inclusive decision-making, and effective governance, still have much room for improvement, and the anticipated likelihood of imminent progress in these areas varies between countries and regions. We discuss the implications of our findings for policymakers and development agencies, and consider potential future applications of our assessment protocol.
Nowhere to belong: Migration narratives in Eeb Allay Oo! (2019) and Gamak Ghar (2019)
Authors: Kaur Harmanpreet
Published: May 2023

This article analyses the narratives of migration in the films Eeb Allay Oo! and Gamak Ghar which also incidentally speak to a moment in India during the pandemic when the precarious lives of migrants working in the informal sector took centre stage in the public discourse. While Eeb Allay Oo! follows the life of a migrant unable to find suitable work till he is recruited as a monkey repeller in central Delhi, Gamak Ghar introspects the idea of home in the filmmaker’s own village near Darbhanga in Bihar when various family members leave it to work and live elsewhere. The article addresses these films through an interdisciplinary lens of migration studies and cinema studies and as alternative to the mainstream commercial cinema of the country in terms of aesthetics and the circular journeys of the filmmakers themselves.
A daydream and a nightmare in Muqaddar Ka Sikandar: Formulas, fantasies and 1970s action Hindi cinema
Authors: Trivedi Pragya
Published: May 2023

1970s Hindi formula films have been described within Hindi film scholarship as melodramatic, and masochistic fantasies, the latter in terms of the hero’s desire to return to a pre-Oedipal state. In my analysis of Muqaddar Ka Sikandar (1978), the biggest hit of the year, I focus on its staging of scenes of fantasy and dream-like episodes and its foregrounding of childhood episodes involving father substitutes, primary figures I argue in the staging. By examining the film’s psychical–spatial terrain, I also consider the figure of the rival and villain, played by Amjad Khan, and I argue that Khan’s villainy reworks scenes of staged enmity with the hero into reconciliation. I conclude with some observations on the contemporary circulation of formula films on YouTube, where the films and their songs remain remarkably popular and generate a large archive of likes, views and comments, and user-generated content.

Authors: Kecsmár Gergő , Czagány Máté , Baumli Péter , Dobó Zsolt
Published: May 2023

The rechargeable metal-air battery technology is a well-interested smart method for eco-friendly and sustainable energy storage. Both of the two order of magnitude lower global market price per tonne of Zn compared to lithium and the multiple theoretical and practical specific energy density of rechargeable ZAB compared to the worldwide Li-ion designs contributes the developing continuously of rechargeable Zn-air battery. The air electrode as a cathode has a vital role in increasing the discharge-charge performance in ZABs, therefore different layers-order air electrodes were assembledwith the utilization of Ni-foam, graphite coating and carbon nanoparticles. The tri-layers cathode showed the highest voltage and performance values compared to the mono- (Ni-foam) and bi- (Ni-foam + graphite coating) layers architectures. The effect of electrolyte inorganic additives (e.g., 2 n/n% ZnCl2 and 0,05 wt% MnO2) was experienced especially at the no-load period.

Published: May 2023

Elasticity and stress absorption are present in many different materials in our daily life. Understanding how materials behave under pressure (whether that is constant or dynamic), and how and when they deform can be fundamental in terms of their success or longevity. Elastic behaviour is present in many different forms in different materials, e.g.: meats or other food. Interestingly, elasticity is also a major issue in the oral cavity, when talking about healthy dental tissues, such as dentin or even special dental restorative materials. The article focuses on the general mechanical behaviour of elastic and viscoelastic materials and measurements performed on them.

Application of respiratory function tests in patients with neurological diseases
Authors: Yoo Ilhan , Choi Seok-Jin , Sung Jung-Joon
Published: May 2023

Breathing is controlled by complex interactions between the central and peripheral nervous systems in conjunction with the respiratory system. Neurological diseases predispose patients to nocturnal desaturation and pneumonia due to respiratory dysfunction, which increases mortality, daytime sleepiness and fatigue, and reduces the quality of life. Respiratory function tests are required to identify respiratory function decline and to consider compensatory management. This review summarizes the characteristics of several respiratory function tests and their applications to neurological diseases.
Autonomic dysfunction in multiple sclerosis and neuromyelitis optica spectrum disorder
Authors: Kwon Soonwook , Min Ju-Hong
Published: May 2023

Autonomic dysfunction occurs frequently in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). Patients with either condition may present with autonomic symptoms such as bladder, sexual, cardiovascular, thermoregulatory, and gastrointestinal dysfunction, and fatigue, but autonomic symptoms that affect quality of life are underrecognized in clinical practice. The immunopathogenesis of MS has been considered to be associated with autonomic dysfunction. Applying appropriate treatment strategies for autonomic dysfunction is important to improve the quality of life of patients. Here we review autonomic dysfunction and how this is managed in patients with MS and NMOSD.

Authors: Kim Changho , Park Jin Sung , Kang Minsung
Published: May 2023

Acute pulmonary embolism (PE) is a life-threatening disease that manifests with cardiorespiratory symptoms. Syncope can be a rare, but warning sign of PE. We report a case of a 49-year-old male diagnosed with PE who presented with recurrent syncope prior to typical cardiorespiratory symptoms. His computed tomography pulmonary angiogram revealed bilateral PE. Syncope can be a rare clinical symptom of PE, but considering lethality of the disease, a differential diagnosis of PE should be considered in patients with recurrent syncope.

Authors: Untari Untari , Anjani Gemala , Fulyani Faizah , Pramono Adriyan , Mahati Endang , Putri Sylvia Rahmi , Maulana Reza Achmad
Published: May 2023

Background: Vitamin D deficiency is frequently correlated with elevated malondialdehyde (MDA) levels and decreased superoxide dismutase (SOD) activity. Several studies have demonstrated that vitamin D3 can reverse intracellular oxidative stress. However, vitamin D is prone to deterioration and instability. Liprotides contain lipids and proteins that can prevent vitamin D from oxidating.Objective: This study aims to investigate the effects of liprotide-encapsulated vitamin D3 on MDA concentrations and SOD activity in calcium and vitamin D-deficient rat models.Methods: The experimental post-test-only control group study used 24 Wistar rats randomly in 4 groups. Groups K(-), K(+), and P were fed a vitamin D and calcium-depleted AIN-93M diet for 14 days. Standard feed AIN-93M was received by normal groups (KN). Groups K- were deficient rats in vitamin D and calcium without intervention. The groups of  K+ and P were given vitamin D3 (180 IU) which was non-encapsulated and liprotide-encapsulated for 28 days.The SOD activity was quantified with Superoxide Dismutase (SOD) Activity Assay Kit, while MDA levels were determined using Thiobarbituric Acid Reactive Substance (TBARS) method. The statistical analysis used One-way ANOVA test with Least Significant Difference follow-up test.Results: The MDA levels and SOD activity in the K+ and P groups had significant differences (p<0.05) against the control group. Liprotides-encapsulated vitamin D3 significantly reduced MDA levels and enhanced SOD activity compared to non-encapsulated in rats with a deficiency in vitamin D and calcium.Conclusion: Liprotide-encapsulated vitamin D3 has the potential to increase SOD activity and decrease MDA levels.

Published: May 2023

The present study focuses on the evaluation of a novel prolonged action fertilizer that has been encapsulated by a combination of carboxymethyl cellulose (CMC) and humic acid (HA). The aim of this research was to investigate the release of the essential plant nutrients: phosphorus, nitrogen, and potassium. This study investigated the material composition and nutrient release properties of a novel prolonged action fertilizer encapsulated by CMC and HA. The release of these nutrients was determined by quantifying their concentrations over time using various analytical techniques, such as photometric, titrimetric, and flame photometric methods. The results revealed that the CMC/HA matrix effectively controlled the nutrient release, with extended-release durations observed under acidic (pH 5.0) and neutral (pH 7.0) conditions compared to alkaline environments (pH 8.5). This indicates that the encapsulated fertilizer is well suited for a variety of soil pH conditions, particularly in acidic and neutral soils. This information could have important implications for the development of more sustainable and environmentally friendly fertilizer technologies.
Preparation and experimental estimation of radiation shielding properties of novel epoxy reinforced with Sb2O3 and PbO
Authors: Almuqrin Aljawhara H. , ALasali Heba Jamal , Sayyed M. I. , Mahmoud K. G.
Published: May 2023

The present work aims to fabricate new inexpensive epoxy-based composites with a concentration described by the formula (90 − x)epoxy + 10Sb2O3 + xPbO, where x = 5, 10, 15, and 20 wt%. The impacts of the substitution of epoxy by PbO on the composite density and radiation shielding properties of the fabricated composites were studied. The density of the fabricated composites varied between 1.30 and 1.49 g·cm−3, enriching the PbO concentration. Utilizing the narrow beam transmission method, the linear attenuation coefficient (LAC) of the fabricated composites was measured using the NaI (Tl) detector as well as radioactive sources Am-241 and Cs-137. The LAC increased by 84% and 18% at gamma-ray energy of 0.059 and 0.662 MeV, when the PbO concentration raised between 5 and 20 wt%, respectively. Then the transmission rate and half-value layer of the fabricated composites were reduced by raising the PbO concentration. Therefore, the fabricated composite has good shielding properties in the low gamma-ray energy interval to be suitable for medical applications and low radioactive waste container constructions.
Index for generalized Fredholm operators and generalized perturbation theory

Published: May 2023

In this paper, we develop some generalized Fredholm perturbation results for bounded linear operators acting on non-reflexive Banach spaces satisfying certain conditions. Furthermore, we investigate the stability of the generalized Schechter S-essential spectrum by means of the so-called generalized Fredholm index. This concept is introduced as a semigroup homomorphism satisfying certain properties. Some generalized Fredholm results for block operator matrices acting on a non-reflexive product of two Banach spaces are also developed.
Reactive compatibilization of polypropylene grafted with maleic anhydride and styrene, prepared by a mechanochemical method, for a blend system of biodegradable poly(propylene carbonate)/polypropylene spunbond nonwoven slice
Authors: Tian Zheng , Zhang Yilu , Xu Nai , Pan Lisha , Feng Yuhong
Published: May 2023

Poly(propylene carbonate) (PPC)/polypropylene (PP) spunbond nonwoven slice has gained more attention, owing to its excellent properties, such as biodegradability, flexibility, biocompatibility, and CO2 utilization. However, the applications of this green material are limited due to the poor thermodynamic incompatibility between PPC and PP. In this paper, PP grafted with maleic anhydride (MAH) and styrene (St) (PP-g-(MAH-co-St)), prepared by a mechanochemical method and having a grafting percentage G
MAH = 1.40 %, was used as a compatibilizer to prepare a biodegradable PPC/compatibilizer/PP composite-spunbond nonwoven slice by melt-blending. The effects of compatibilizer content on the tensile strength, elongation at break, melt flow rate, thermal properties, and micro-morphology of PPC/PP-g-(MAH-co-St)/PP were systematically studied. Furthermore, the mechanism of compatibilization of PP-g-(MAH-co-St) in the PPC/PP spunbond nonwoven composite slice is discussed. The results indicated that this green PP-g-(MAH-co-St) exhibited a clear reactive compatibilization effect. Therefore, it can be considered as a good compatibilizer for the biodegradable PPC/PP spunbond nonwoven slice.

The Use of Social Media by Emergency Stakeholder Groups: Lessons Learned from Areas Affected by Hurricanes Isaac and Sandy
Authors: Kirby Ryan H. , Reams Margaret , Lam Nina S.-N.
Published: May 2023

We present findings from our 2018 survey of organizations involved in emergency management in areas affected by Hurricanes Sandy and Isaac to gain insight into their social media use throughout the four phases of emergencies – preparedness, response, recovery, and mitigation planning. While 90% of the 269 respondents report using social media in their communications with the public, government offices are more active throughout the four phases compared to the other groups. First responders use social media most during the response and preparedness phases, while news media and NGOs are more active during the recovery phase. This suggests that groups that perform emergency-response functions and NGOs play complementary roles in emergency communications. Further, respondents representing government offices and first responders use social media primarily to disseminate information, while news media groups and NGOs expressed more confidence in social media as a mechanism for bi-directional communications. While Facebook is most commonly used to respond to the public, the NGOs and news media groups also use newer, image-based options like Instagram. All groups reported less social media use during the quiet time (mitigation planning phase) between emergencies, suggesting opportunities for these organizations to increase communications with the public before emergencies arise.
Fast multilevel iteration methods for solving nonlinear ill-posed problems
Authors: Yang Suhua , Luo Xingjun , Zhang Rong
Published: May 2023

We propose a multilevel iteration method for the numerical solution of nonlinear ill-posed problems in the Hilbert space by using the Tikhonov regularization method. This leads to fast solutions
of the discrete regularization methods for the nonlinear ill-posed equations.
An adaptive choice of an a posteriori rule is suggested to choose the stopping index of iteration,
and the rates of convergence are also derived. Numerical results are presented
to demonstrate the efficiency and accuracy of the proposed method.
Heterogeneously integrated light emitting diodes and photodetectors in the metal-insulator-metal waveguide platform
Authors: Kwon Kyungmok , Park Junghoon , You Jong-Bum , Yu Kyoungsik
Published: May 2023

We demonstrate heterogeneous integration of active semiconductor materials into the conventional passive metal-insulator-metal (MIM) waveguides to provide compact on-chip light generation and detection capabilities for chip-scale active nanophotonic platforms. Depending on its bias conditions, a metal-semiconductor-metal section can function as either a light emitting diode or a photodetector directly connected to the MIM waveguides. We experimentally verify the independent and combined operations of electrically-driven on-chip light sources and photodetectors.
Dynamic selection of visible wavelengths using resonant TiO2 nanostructures
Authors: Um Han-Don , Choi Deokjae , Solanki Amit , Huang Emerald , Seo Kwanyong , Habbal Fawwaz
Published: May 2023

All-dielectric nanoarrays have strong electromagnetic resonances with various interesting applications and are tuned by adjusting their geometrical parameters. However, their optical properties are permanently encoded during fabrication. This study presents robust dynamically tunable all-dielectric nanoresonators for controllable, reversible, and reproducible color filtering. Our design uses an array of TiO2 nanodiscs embedded in a transparent, stretchable polydimethylsiloxane (PDMS) membrane and exhibits a narrow spectral response due to Mie magnetic and electric dipole resonances hybridized with the TiO2 nanodiscs lattice modes. By mechanically stretching the PDMS membrane, the pitch of the TiO2 nanodiscs was increased and the spectral location of the resonances was altered. Additionally, an optically asymmetric structure was fabricated by partially embedding TiO2 nanodiscs in PDMS. Thus, the magnitude of the Rayleigh anomaly diffraction, which could interrupt the dipole resonances, was reduced. Our design has sharp, frequency-tunable resonances in the visible spectrum, and we demonstrated dynamic tunability by stretching the metasurfaces.
Az életstílus applikációk használatának megítélése egy kísérlet tapasztalatai alapján

A TANULMÁNY CÉLJA
Világszerte számos kutatást végeztek az m-health applikációkkal kapcsolatban, és az eredmények azt mutatják, hogy a jól megtervezett m-health alkalmazások javíthatják a gyógyszeres kezelést, és csökkenthetik az egészségügyi ellátás költségeit. Kutatásunk célja, hogy feltárjuk az m-health applikációk és különös tekintettel az életstílus-alkalmazások használatának elméleti hátterét és tapasztalatait felhasználói szemszögből.
ALKALMAZOTT MÓDSZERTAN
Az m-health alkalmazások használatát vizsgáló kérdőívek (MAUQ) közül az önálló applikációkra kifejlesztett skálát használtuk. Az applikációk értékelése három dimenzió mentén történt: a használat könnyűsége, az applikáció felületével való elégedettség, és a hasznosság megítélése. A két kutatási kérdés vizsgálatához kísérleti módszert alkalmaztunk, amit 22 hallgató bevonásával bonyolítottunk le, a 2021-es tanév őszi félévében, 14 héten keresztül. Az elemzés során leíró statisztikai mutatókat és páros t próbát alkalmaztunk.    
LEGFONTOSABB EREDMÉNYEK
A vizsgált alanyok összességében 16 különböző applikációt értékeltek,  melyek az életstílus applikációk öt területéhez sorolhatók: (1) sport és fitnesz tevékenységmérő, (2) étrend és táplálkozás, (3) stresszoldás és relaxáció, (4) női ciklus figyelés, illetve (5) betegségkezelés. A kísérletben résztvevő alanyok leginkább a könnyű használattal elégedettek és legkevésbé az applikációk felületével, valamint annak hasznosságának megítélésével. A kísérleti alanyok közül többen számoltak be pozitív hatásokról a fizikai és a mentális egészség javulása által. Az észlelt egészségjavulás szignifikáns (t=-4,55; p≦0,00) és a legkedvezőbb változás a diéta és táplálkozási alkalmazások esetében figyelhető meg. Biztató, hogy 17-en tervezik az applikációk további használatát. 
GYAKORLATI JAVASLATOK
Kutatásunk eredményei különösen hasznosak lesznek az egészségtudatosságra és egészségfejlesztésre fókuszáló fogyasztók, alkalmazásfejlesztők és szolgáltatók számára. Az egészségügy esetében hozzájárulhat az ellátórendszer terheinek csökkentéséhez, valamint a telemedicina és a hagyományos egészségügy integrált fejlesztéséhez. Népességi szinten kiemelt szerepe van a megelőzés területén. A fejlesztőknek érdemes lenne nagyobb figyelmet szentelni az appok felületének fejlesztésére, a design-ra, a rendszerezésre, vagyis ergonómiai szempontokra. Ezen kívül, a fejlesztők számára lehetőséget kínál az ingyenesen elérhető szolgáltatások bővítésére, valamint a BigData adatok GDPR előírásainak megfelelő kezelésére, elemzésére.

Awareness of, and debate about, harassment, assault, bullying and intimidation (HABI) in archaeology has grown in recent years, but the issue remains under-researched. Here, the authors present the first Europe-wide survey to evaluate HABI in archaeological environments, from field to laboratory and classroom. The survey covers 18 forms of HABI, collecting more than 1000 responses from archaeologists of 49 nationalities. A total of 82 per cent of respondents report at least one HABI experience. The authors conclude that HABI is endemic in European archaeology, being experienced by all genders and ages, in multiple settings and countries. Documenting these behaviours is a critical first step to eradicating them and to achieving equity and safety in the discipline.
Correlates of Internalized HIV Stigma: A Comprehensive Systematic Review

Published: May 2023

Internalized HIV stigma is prevalent and research on internalized HIV stigma has increased during the past 10 years. The aim of this systematic review was to synthesize research on internalized HIV stigma and relationships with various health-related variables in order to better inform the development of interventions aimed at reducing internalized HIV stigma. We reviewed 176 studies with a quantitative design reporting correlates that were peer-reviewed, published in English before January 2021, drawn from PubMed, PSYCHINFO, Web of Science, EBSCO, and Scopus. Synthesis showed consistent associations between internalized stigma and negative psychological (e.g., depression, anxiety), social (e.g., lack of social support, discrimination, nondisclosure, and intersecting stigmas), and health (e.g., substance use, treatment nonadherence, negative clinical HIV outcomes) variables. We argue for a more socioecological approach to internalized stigma, with greater attention for intersectional stigmas, and more longitudinal research, if we are to effectively develop interventions that reduce internalized stigma.
Mechanism of 5S RNP recruitment and helicase‐surveilled rRNA maturation during pre‐60S biogenesis

Ribosome biogenesis proceeds along a multifaceted pathway from the nucleolus to the cytoplasm that is extensively coupled to several quality control mechanisms. However, the mode by which 5S ribosomal RNA is incorporated into the developing pre‐60S ribosome, which in humans links ribosome biogenesis to cell proliferation by surveillance by factors such as p53–MDM2, is poorly understood. Here, we report nine nucleolar pre‐60S cryo‐EM structures from Chaetomium thermophilum, one of which clarifies the mechanism of 5S RNP incorporation into the early pre‐60S. Successive assembly states then represent how helicases Dbp10 and Spb4, and the Pumilio domain factor Puf6 act in series to surveil the gradual folding of the nearby 25S rRNA domain IV. Finally, the methyltransferase Spb1 methylates a universally conserved guanine nucleotide in the A‐loop of the peptidyl transferase center, thereby licensing further maturation. Our findings provide insight into the hierarchical action of helicases in safeguarding rRNA tertiary structure folding and coupling to surveillance mechanisms that culminate in local RNA modification.

Authors:   Moscow Pedagogical State University, Demakova Irina D.
Published: May 2023

Introduction to the problem. Scientists associate the modern development of longitudinal methods with the development of data analysis methods, which are determined at the stage of research planning, as well as when testing hypotheses about development, about long-term or delayed effects of experimental influences. In its most general form, longitudinal can be understood as a group of methods characterized, in contrast to cross-sectional studies, by the presence of several repeated measurements of one or more variables of interest to the researcher on the material of the same or similar groups of subjects. The purpose of the article is to determine the conditions for the effectiveness of the results of the educational activities of teachers, the development of the concept of the educational activities of the teacher as a factor in the humanization of the space of childhood. The longitudinal method in the field of education is described, when the teacher works steadily for a long time with the same group of children for a period of time sufficient to determine significant changes in their behavior, worldview, etc. Research results. The article includes an analysis of three sections: 1963–1966; 1967–1978; 1979–2011. The educational activity of a teacher (class teacher), aimed at humanizing the space of childhood, provides a process of step-by-step and systematic transformation of a spontaneously assembled group of children (participants in a longitudinal study) into a cohort: a group of associates, people strongly united by common ideas, goals and aspirations. Conclusion. The use of longitudinal methods in pedagogy is very promising: they help to trace the influence of external factors, various events or incidents on a child’s life over a certain period of time; give the teacher the opportunity to observe the child for a specific period of time, to record changes in his psychological, physical and mental state, to ensure the process of forming his personality, to study the properties of his character.

Authors:   Novosibirsk State Pedagogical University, Zasmolina Natalya P. , Romm Tatiana A. ,   Novosibirsk State Pedagogical University
Published: May 2023

The article actualizes the importance of early formation of adolescents’ self-organization culture and substantiates the judgment that the vector of pedagogical assistance should be aimed at increasing the self-organization of personality. The aim of the article is to identify and substantiate the essence of the stages of formation of adolescents’ self-organization culture in the process of education. Methodology. During this study, we used analysis of domestic and foreign literature on the problem of research, the method of participant observation, questioning of teachers and students 13-14 years, generalization of pedagogical experience. Results. Relying on the leading pedagogical ideas of E. A. Aleksandrova, N. B. Krylova and T. A. Romm, during theoretical and empirical research on the basis of intellectual and game activities we have identified and substantiated the main stages of formation of the teenagers’ self-organization culture – initiation, enculturation and transformation. The effectiveness of pedagogical assistance at each stage is achieved if the teacher’s educational strategies become joint activities, subject-subject interaction, teaching effective ways of self-organization, development of subjectivity and sociality of the adolescent through cultural practices. Conclusion. The results obtained allowed us to conclude that an effective means of fostering the culture of self-organization of adolescents is intellectual and game activities that develop the personal qualities and abilities of the adolescent, providing the formation and development of self-organization as a condition of personal effectiveness in modern society.
Antenatal steroids: benefits, risks, and new insights
Authors: Fee Erin L , Stock Sarah J , Kemp Matthew W
Published: May 2023

Being born before 37 weeks’ gestation, or preterm birth, is a leading cause of early childhood death and life-long disability. Antenatal steroids (ANS) are recommended for women judged at risk of imminent preterm delivery. The primary intent of ANS treatment is to rapidly mature the fetal lungs to reduce the risk of mortality and lasting morbidity. Despite being used clinically for some 50 years, a large number of uncertainties remain surrounding the use of ANS. In particular, the choice of agent, dose/regimen, and appropriate gestational age range for ANS therapy all remain unclear. Unresolved concerns regarding the potential risk of harms from ANS treatment, especially in light of the modest benefits seen with expanding latepreterm administration, make it increasingly important to optimize the dosing and application of this important and widely used treatment. This review will serve to summarize past data, provide an update on recent developments, and chart a way forward to maximize the overall benefit of this important therapy.
LA EXPERIENCIA ESTÉTICA DEL SONIDO EN EL ESPACIO. UN CONTRASTE FILOSÓFICO ENTRE ESPACIO ARQUITECTÓNICO Y ESPACIO SONORO
Authors: Balbontín Sofía
Published: May 2023

Este artículo pretende discutir la noción de espacio-sonoro a partir de la experiencia estética del sonido en el espacio, observando los principios acústicos que construyen espacios conformados únicamente por la percepción sonora. Se reconocen dos tipos de espacios-sonoros; el espacio invisible construido por el sonido (espacio-de-sonido) y el sonido emitido por el espacio físico (sonido-del-espacio). En ambos casos la percepción auditiva es el acceso cognitivo a la información espacial, sin embargo, el primero se reconoce desde la escucha acusmática, mientras que el segundo se reconoce a través del proceso de ecolocalización. Para encauzar este proceso se establece un contraste filosófico entre espacio-arquitectónico y espacio-sonoro, como también en las relaciones que aparecen entre el espacio-de-sonido y el sonido-del-espacio. Se toman como base para la discusión, los conceptos de “lo liso” y “lo estriado” propuestos por Gilles Deleuze y Felix Guattari en su libro Mil Mesetas: Capitalismo y Esquizofrenia. De este análisis se desprende que el espacio-sonoro no solo potencia la estética de la escucha como una poderosa herramienta creativa, sino que además remece los cimientos disciplinares de la arquitectura para incorporar dentro de sus métodos de diseño y producción a la percepción como material de construcción de espacialidades.
