High-Selectivity-Based Novel Split-Gate VTFET Biosensor for Identification of SARS-CoV-2
Authors: Theja A. , Ambekar Vikas , Panchore Meena
Published: March 2024

The World Health Organization (WHO) has officially declared the international outbreak of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), often known as Coronavirus Disease 2019 (COVID-19), a global pandemic based on the significant and sudden increase in human infections worldwide. With suitable treatment and early diagnosis, this outbreak can be controlled to a certain extent. In the present research, the performance of a novel dielectrically modulated heterojunction-based splitgate double cavity vertical TFET biosensor for detecting SARS-CoV-2 with reference to the virus spike, DNA and envelope proteins has been thoroughly investigated. The suggested sensor’s sensitivity has been evaluated through the computation of the deviation in drain current. We model the hybridized biomolecules in the nanogaps as the dielectric constant equivalent of the viral proteins. Additionally, sensing speed and selectivity analysis pertaining to the various biomolecules are also investigated. The proposed sensor exhibits a notably high sensitivity (on the order of 108), high sensing speed, and high selectivity (on the order of 106), indicating its potential as a superior sensor. This study also examines the influence of variations in DNA charge density on the performance of the device. Ultimately, the proposed sensor is evaluated in comparison to its sensitivity and selectivity of a variety of FET-based biosensors previously documented in the literature.

Published: March 2024

Highly textured phase pure Cu2O thin films have been grown by a simple electrodeposition technique with varying deposition voltages (−0.3 to −1.0 V). The surface morphology characterized by Scanning Electron Microscopy (SEM) revealed that the deposited thin films coherently carpet the underlying substrate and are composed of sharp faceted well-defined grains of 0.5–1.0 μm sizes. XRD analyses showed that all films are composed of polycrystalline cubic Cu2O phase only and have average crystalline domain size in the range of 30–73 nm. The preferred crystalline orientation of phase pure Cu2O films was found to be changing from (200) to (111) with increasing cathodic voltages and showed the highest (111) and (200) crystalline texture coefficient while growing at −1.0 and −0.8 V respectively. The optical bandgap of the as-grown samples was calculated in the range of 1.95–2.20 eV using UV–vis Transmission data. The performance of Cu2O/FTO photocathodes was tested by estimating LED “ON/OFF” modulated surface photovoltage into a photoelectrochemical cell at a zero bias.
Properties and Behaviors of Heavy Quarkonia: Insights through Fractional Model and Topological Defects
Authors: Abu-shady M. , Fath-Allah H. M.
Published: March 2024

In this study, we investigated the impact of a topological defect (λ) on the properties of heavy quarkonia using the extended Cornell potential. We solved the fractional radial Schrödinger equation (SE) using the extended Nikiforov-Uvarov (ENU) method to obtain the eigenvalues of energy, which allowed us to calculate the masses of charmonium and bottomonium. One significant observation was the splitting between nP and nD states, which attributed to the presence of the topological defect. We discovered that the excited states were divided into components corresponding to 2l+1, indicating that the gravity field induced by the topological defect interacts with energy levels like the Zeeman effect caused by a magnetic field. Additionally, we derived the wave function and calculated the root-mean radii for charmonium and bottomonium. A comparison with the classical models was performed, resulting in better results being obtained. Furthermore, we investigated the thermodynamic properties of charmonium and bottomonium, determining quantities such as energy, partition function, free energy, mean energy, specific heat, and entropy for P-states. The obtained results were found to be consistent with experimental data and previous works. In conclusion, the fractional model used in this work proved an essential role in understanding the various properties and behaviors of heavy quarkonia in the presence of topological defects.

Published: March 2024

Background. Premature infants are exposed to numerous stressors in neonatal intensive care unit (NICU) during a crucial period for brain development; this period exerts long-term influences on cognitive and behavioral development. Aims. To evaluate the effect of NICU-related stress on neonatal rat pups and explore the effect of Chinese medicine treatment (CMT). Methods. Sixty male rat pups were randomly assigned to three groups: the control group, the NICU group (NICU-related stress), and the CMT group (NICU-related stress plus CMT). All stressors and interventions were administered from 0 to 7 days after birth. Body weight, serum corticosterone levels, and behavior in the open field (OF) test, elevated plus maze (EPM) test, sucrose preference test, and Morris water maze (MWM) test were recorded, and blood samples were collected at five different time points (T0, T1, T2, T3, and T4). Results. The body weights of rats in the CMT and control groups were heavier than those in the NICU group in both early life and adulthood (P<0.05). Serum corticosterone levels significantly differed with time (except T0 vs. T1 and T3 vs. T4) but did not significantly differ among the three groups (F=0.441, P=0.894). Regardless of age, spatial memory and anxiety-like and depression-like behavior did not differ among the three groups. Conclusion. NICU-related stress exerted a long-term effect on rat growth and development but did not affect spatial memory, anxiety-like behavior, depression-like behavior, or serum corticosterone levels. CMT alleviated the impact of NICU-related stress on rats and promoted the growth and development of neonatal rats.

Published: March 2024

Immune thrombocytopenic purpura (ITP) is an immune-mediated disorder characterized by the destruction of platelets and megakaryocytes due to autoantibodies against the platelet surface proteins. ITP without any apparent cause of thrombocytopenia is defined as primary ITP, and ITP in the setting of SLE is secondary ITP, which can be diagnosed after excluding other causes of thrombocytopenia by history, physical examination, and laboratory testing. Patients with ITP associated with SLE have higher median platelet count and less bleeding manifestations compared to the patients with primary ITP. It can be very challenging to diagnose primary ITP in SLE patients as other causes of thrombocytopenia including drug-induced thrombocytopenia, antiphospholipid syndrome, and thrombotic microangiopathic process should be ruled out. Corticosteroids are the main modality of treatment. IVIG can be used in severe cases. Splenectomy was found to be less effective in ITP associated with SLE compared to primary ITP. Control of disease activity with immunosuppressive therapy can be helpful in some cases associated with active disease flares in SLE patients.

This study aimed to evaluate whether total replacement of soybean meal (SBM) with sundried soymilk residue (SSR) in a total mixed ration (TMR) affects intake, digestibility, milk production, and blood metabolites in dairy goats. A total of 12 healthy Saanen dairy goats (40.12 ± 5.80 kg of BW) in midlactation (31.23 ± 10.12 days) were used in a randomized complete design (n = 4 goats/group). Dietary treatments were based on a TMR as follows: control TMR without SSR (CON) or SBM‐based TMR with 50% or 100% of SSR replacing SBM (SSR‐50 and SSR‐100, respectively). All goats had ad libitum access to feed and clean water throughout the experiment. The dry matter (DM) intake decreased (p < 0.05) with the increasing replacement ratio of SBM and was lowest in the SSR‐100 group. Similarly, organic matter (OM) digestibility was lowest (p < 0.05) in the SSR‐100 group. However, the digestibility of DM, CP, NDF, and ADF did not change (p > 0.05) by dietary treatments. Compared with CON, the milk yield decreased significantly (p < 0.05) with increasing replacement ratio of SBM. In contrast, milk composition such as total solids, solids‐not‐fat, milk fat, lactose, protein, and pH were not influenced (p > 0.05) by feeding dietary SSR. Compared with other treatments, blood glucose concentration was lower (p < 0.05) in the SSR‐100 group. In contrast, packed cell volume, glucose, and plasma urea nitrogen concentrations did not differ (p > 0.05). The results indicated that SSR could replace SBM in a TMR at less than 50%. Thus, the present study provides support for further investigation to enhance the utilization of soybean waste as an alternative protein source in the TMR for dairy goats and potentially other ruminants.
Hydrogen as Fuel for ICEs: State of Art and Technological Challenges
Authors: Cecere Giovanni
Published: March 2024

The climate change, as the main consequence of the polluting emissions due to anthropic activities, is nowadays a well‐known threat to human health as well as for the environment safety. Several plans and strategies have been announced by the governments to detach from fossil fuel‐based energy and gradually reduce the carbon footprint of their economies. In this scenario, the road transport sector is turning out to be the main “technological gym” to test and improve new powertrain solutions to achieve as soon as possible the goal of the net‐zero carbon emissions, at least in the tank‐to‐wheel (TTW) context. In view of this, the hydrogen as fuel is gaining ever more attention from the scientific community, both as the middle‐term solution to achieve the abovementioned goal and as a prominent future energy carrier. In this review, the performance and main characteristics of the hydrogen‐internal combustion engines (H2‐ICEs) are discussed based on the most recent studies available in literature. A comprehensive overview of various topics is offered, from the production stage to the combustion anomalies, mixture formation strategies, and the challenge of reducing the nitrogen oxides (NOx) emissions under high load conditions.

Published: March 2024

O texto apresenta o projeto 90 miles, de autoria do fotojornalista Michael Christopher Brown, que traz fotografias construídas a partir do Midjourney, gerador de imagens por Inteligência Artificial que tem ganhado protagonismo na atualidade. Sendo estas imagens caracterizadas pelo próprio fotógrafo como um experimento de produção pós-fotográfica, e considerando o fato de que sua construção se deu sem o confronto entre câmera e os eventos factuais representados nas imagens, discute-se a viabilidade de enquadrar o projeto como uma fotorreportagem em sintonia com a realidade de produção e circulação da imagem na contemporaneidade.

O uso de equipamentos portáteis à sensação câmera do kitesurf
Authors: Bortolini Karen Sales
Published: March 2024

O uso de câmeras portáteis para capturas de imagens de esportes radicais possibilita gerar impressões subjetivas pela densidade das tomadas que promove. Atletas portam os pequenos dispositivos como extensões do corpo à construção de planos que representam movimentos de desempenho cada vez mais próximos de aspectos da ordem da realidade. Portanto, investigar sobre as relações do homem com os aparatos tecnológicos pode contribuir para a compreensão de como esses resultados são apresentados no cinema contemporâneo, mais especificamente no gênero documental. Para isso, este artigo relaciona o procedimento empírico ao aporte teórico da comunicação, da tecnologia e do cinema, norteado por autores como Marshall McLuhan, Marialva Barbosa, Álvaro Vieira Pinto e Arlindo Machado. Para esta pesquisa, foram captadas imagens, em julho de 2017, da modalidade kitesurf, com o uso de equipamentos portáteis, incluindo câmeras promotoras de imagens objetivas para captação de manobras e depoimentos e pequenas câmeras usadas para o registro de imagens subjetivas com impressão de movimento. Este esporte radical foi disseminado em diversos países e ganha adeptos no Brasil, desde sua chegada, em 2000, conquistando sua participação pela primeira vez nos Jogos Olímpicos em 2024, em Paris (FR). As imagens para sua análise foram geradas na vila de pescadores do Preá, município de Cruz, próximo ao destino turístico internacional Jericoacoara, no Ceará. A região é polo da prática por apresentar condições específicas para o desempenho, como a intensidade e direcionamento de vento necessários.

Published: March 2024

A partir da experiência do núcleo de pesquisa “Intertrads” em processos e interação constrói-se esta pesquisa. Fundamenta-se na abordagem dialógica da linguagem (Bakhtin e o círculo) e na abordagem semiológica para estudo das línguas de sinais (CUXAC, 2000), principalmente, da iconicidade constituindo a essência de uma gramática visual-espacial. Com um estudo de caso, apresentamos exemplos retirados de nosso corpus de vídeos análise documental (de traduções produzidas pelo Núcleo de pesquisa “XXXX” [nome ocultado para manter a avaliação as cegas]), e sinais-termos padronizados publicados no glossário de sinais-termos disponibilizadas em canal do Youtube do núcleo de pesquisa, assim como das reflexões provenientes da observação participante em grupo de pesquisa de falantes nativos surdos engajados em atividades dialógicas. Discute-se as possibilidades de empregar os princípios da “expressão altamente icônica” no discurso espontâneo na elaboração de sinais-termos conceituais e acadêmicos em processos de tradução de português para a Libras.

Published: March 2024

This article analyzes the first season of the Netflix series "Bridgerton," which was adapted from the first book in the "Bridgerton" series, "The Duke and I," written by Julia Quinn. It does so by drawing on a variety of viewpoints to offer fresh perspectives and promote intercultural conversations. The categories of "alteration," "omission," and "addition", adapted from interlingual translation, are used to discuss the changes that resulted from the translation of one sign into another. In this work of bibliographical origin, writers with experience in translation were chosen, and as the study includes a case study, books, interviews, and articles from online magazines served as sources, giving a more in-depth understanding of the object mentioned. The adaptation from a literary work to an audiovisual one, as suggested in this article, results in the source work being transformed, through alterations, additions and omissions. The additions and changes to the series opened a discussion about racial issues and, since this work involves qualitative research, it points out how these modifications affect both the media and society, highlighting the significance of having conversations about the matters above mentioned. Additionally, the racial representativeness shown in the series had wide acceptance and support from the general audience. All in all, this article develops topics such as: intersemiotic translation, ethnic-racial issues and analysis of the differences exposed in the series adapted from the book “The duke and I”.

Contribuições metodológicas para a análise dos músicos e instrumentos sonoros no mundo andino pré-hispânico: discutindo suas identidades e papéis sociais através de estudos de caso Mochica e Nasca
Authors: Chioma Daniela La
Published: March 2024

Os estudos sobre a música andina no período pré-hispânico têm aumentado significativamente nas últimas duas décadas. A maior parte deles são fundamentados em evidências acústicas, particularmente instrumentos sonoros arqueológicos. No entanto, mesmo que as referências musicais sejam prolíficas e variadas na arte andina pré-hispânica, poucas pesquisas foram elaboradas sobre os abundantes dados iconográficos. Dentre elas, a nossa. Este artigo pretende abordar as antigas práticas musicais andinas e os papéis sociais e religiosos dos músicos a partir de uma perspectiva da História da Arte, discutindo os dados dentro de uma metodologia de análise semiótica. Buscamos, além de compreender aspectos musicais das sociedades do Peru antigo a partir de dados não sonoros, trazer uma contribuição metodológica na análise da iconografia musical em geral fundamentando-nos em premissas e perguntas que podem ser aplicadas para além das evidências do mundo andino. Considerando o caráter interdisciplinar da arqueomusicologia, buscamos respostas em dados tanto arqueológicos quanto etnomusicológicos e históricos.
A música no programa de poder de Nero: a evidência das moedas
Authors: Cerqueira Fábio Vergara , Armesto Caroline Melo
Published: March 2024

O presente estudo tem como objetivo analisar a relação entre a música e o poder imperial de Nero, explorando, em particular, a representação do imperador como Apolo citaredo nas moedas cunhadas durante sua turnê pela Grécia entre 66 a 67 d.C. Por meio da iconografia dessas moedas, busca-se compreender as intenções políticas e culturais subjacentes à imagem de Nero como Apolo citaredo. A análise proposta neste estudo sugere que o filelenismo neroniano deve ser entendido como um projeto político e cultural que envolve a experiência estética, e não como uma simples manifestação da afeição pessoal de Nero pela cultura grega.
Effect of eight weeks of combined exercise and omega-3 supplementation on the levels of inflammatory and anti-inflammatory cytokines in elderly women
Authors: Sobhani V. , Shakibaei R. , Gholami M. , Arabzadeh E.
Published: March 2024

Exercise training and omega-3 supplementation are known to have anti-inflammatory effects; however, the simultaneous effect of exercise training and omega-3 supplementation has received little attention so far. The present study aimed to investigate the effect of combined training (resistance endurance) and omega-3 supplementation on the levels of inflammatory and anti-inflammatory cytokines in older women. The 40 participating older adults, with an average age of 66.7 ± 4.13 years, were randomly assigned to four groups: placebo, omega-3, training and training + omega-3. Combined exercise training (consisted of 30 mins running with 40-70% of reserve heart rate and resistance training included ten exercises, two sets, and each set consisted of 18-20 repetitions) performed for eight weeks and three sessions per week. Omega-3 supplementation was 2,000 mg daily (two 1000 mg capsules, one in the morning and one at night). Blood sampling was performed in pre and post-test (48 h after the last training session and omega-3 supplementation) stages, and interleukin (IL)-6, tumour necrosis factor (TNF)-α, and IL-10 levels were measured by ELISA. The dependent t-test results (pre- and post-test) indicated that there was a statistically significant difference (decrease) in HOMA-IR index, body fat percentage, body mass index, IL-6, and TNF-α in training and training + omega-3 groups, post-exercise (). TNF-α was lower in the omega-3 () training () and training + omega-3 () groups compared to the placebo group, post exercise. Moreover, IL-6 levels in the training () group were lower than in the placebo group, post exercise. Combined training may reduce both TNF-α and IL-6 compared to placebo. In contrast, omega-3 alone or combined with combined training may only reduce TNF-α but not IL-6 concentrations compared to placebo.
Cardiovascular response to body positioning following sub-maximal exercise test among long-COVID individuals
Authors: Sharma A. , Pawaria S. , Reyalch N.
Published: March 2024

This study aimed to observe the effect of cardiovascular response to body positioning after cardiopulmonary exercise testing in post covid individuals. Ninety post covid participants (age group 18-45) were assigned into four groups: standing, sitting, supine, and prone position. All participants were assessed cardiovascular response, VO2max baseline, post exercise in standing, sitting, supine and prone by using pulse oximeter, digital sphygmomanometer, polar heart rate and Borg scale. In SpO2, rate of perceived exertion (RPE), diastolic blood pressure, and heart rate, there was no significant difference between the groups at pre-exercise. However, a significant difference was observed at 1 min post-exercise and at 3 min post-exercise. As for systolic blood pressure, there was no significant difference between the groups at pre-exercise and at 1 min post-exercise, but a significant difference was noted at 3 min post-exercise. The findings of this study suggest that, when comparing standing, sitting, supine, and prone positions, the prone position exhibited faster recovery in terms of oxygen saturation and rate of perceived exertion, while the supine position showed quicker recovery in both systolic and diastolic blood pressure. Additionally, individuals with long-COVID symptoms were observed to have a lower VO2max.
The Amateur Astronomer as Image Producer
Authors: Guignard Laurence
Published: March 2024

This article approaches the history of amateur astronomers in the late nineteenth century via visual and material sources. It adopts three separate viewpoints: Jules Pierrot Deseilligny’s home-based workshop, two self-portraits of amateurs at work, and a corpus of selenographic images published in the Bulletin de la Société Astronomique de France. These sources throw light on amateur savant practices, which are largely based on producing images, sometimes taking the form of a structured scholarly project, and giving rise to exchanges, debates, and sociabilities. It identifies a proliferation during the years 1880 to 1914, characterised by a particular sensitivity to the extraterrestrial life feeding a powerful desire to observe the surface of the moon.
To Press, Dry, Organise, and Represent
Authors: Esmeral Henriquez Maria Angelica
Published: March 2024

This paper examines the epistemological relation between two types of scientific image produced during a botanical expedition to New Granada in the late eighteenth and early nineteenth centuries: herbarium sheets and botanical illustration. Visual analysis of an exceptional collection of these two types of documents brings to light how scientific ideologies were transferred from Europe to New Granada, during the transformation of this latter from a colony to a republic. This study shows how features such as composition, proportion, and pictorial technique derive from both aesthetic choices and epistemological necessities. It reveals the development of a codified visual language resulting from a highly organised and structured outcome, complying with Carl Linnaeus’ principles of classification, and materialising a new way of looking at plants based on Isaac Newton’s universal mathematical principles.
Ammonia emissions related to black soldier fly larvae during growth on different diets
Authors: Coudron C.L. , Berrens S. , Van Peer M. , Deruytter D. , Claeys J. , Van Miert S.
Published: March 2024

Black soldier fly (Hermetia illucens) is considered a farmed animal. The larvae live in a moist substrate, which leads to a complex interaction with the microbial community. As such the combined metabolism of the insects and that of the microbial community can ultimately lead to all sorts of emissions such as ammonia and greenhouse gases. For ammonia emissions and associated depositions, it is known that this can lead to eutrophication of local ecosystems and the formation of particulate matter which can affect human health. This issue is known for intensive livestock farming where in some Western European countries this has led to specific regulations, for example limited number of livestock per farm, to control ammonia emissions. The production of black soldier fly larvae is a novel activity that could similarly lead to ammonia emissions. This study introduces a new method to quantify ammonia emissions in an industrial setting using an accumulation chamber and validates the findings with a nitrogen mass balance. Additionally, different feed substrates (Gainesville diet, chicken feed, artificial supermarket waste and brewers spent grains) were assessed with varying crude protein concentrations, hypothetically one of the driving factors affecting emissions. Results indicate significant ammonia emissions, the total emissions during larval growth ranged from 2.6 up to 83.6 g N/kg larvae (dry matter basis) and depend strongly on the diet. The rates at which these emissions are produced are negligible during the first three days. In the following days all diets emitted ammonia at a varying rate. The highest observed hourly emission rate for test substrates could be as low as 6.8 mg N/kg initial substrate (dry matter basis) and as high as 306 mg/kg. Different properties of the feed, such as the initial crude protein concentration, but also how the pH changes throughout larval growth, will affect emissions.
Unseen: A Video Essay
Authors: Isom Philippa
Published: March 2024

This essay and accompanying video explore the concept of the unseen as a posthuman position and its impact on teaching and learning. It theorises how the covid-19 pandemic and virtual learning environments have revealed previously unseen aspects of students’ lives, such as their working spaces and home environments. Drawing on posthuman philosophy and the rhizome metaphor to consider the complex and interconnected nature of the unseen, the essay discusses how awareness of the unseen is crucial for effective teaching. This essay also describes the development of the short film Unseen, which was inspired by my own unseen struggles whist trying to develop a presentation for the Association of Visual Pedagogies twitter conference. The film is an invitation to consider unseen aspects of your own life that may affect your learning and teaching, with an extended invitation to engage in further shared thinking via Padlet.

Background

Carnitine is essential for fatty acid metabolism. Free carnitine (FCA) is excreted in the urine in the glomerulus, but is partly reabsorbed by a carnitine transporter. The mechanism underlying the decrease in serum carnitine level during pregnancy is unclear.

Objective

To investigate whether low carnitine level is associated with increased renal excretion in pregnant women.

Methods

We recruited 43 healthy pregnant and 25 non-pregnant women. Total carnitine (TCA) and FCA levels were measured using the enzymatic cycling method, and the acylcarnitine (ACA) level was calculated. Fractional excretion (FE) was calculated as carnitine clearance divided by creatinine clearance.

Results

The mean TCA, FCA, and ACA levels were lower at 12 weeks of gestation in pregnant than non-pregnant women ( P < .001); the levels decreased further at 36 weeks, reaching 39%, 36%, and 52% of those in non-pregnant women, respectively ( P < .001). The FEs were 3–4-fold higher in pregnant women than non-pregnant women. Pregnant women had a lower serum FCA/TCA ratio than non-pregnant women (0.788 ± 0.098 vs 0.830 ± 0.074, respectively; P < .05), whereas the urine FCA/TCA ratio was similar between the groups.

Conclusion

Low carnitine level is associated with increased renal excretion during late pregnancy.
Coping Following Bereavement: Comparing European American and Japanese Emerging Adults
Authors: Okumura Kiho , Feeney Sarah L. , Claridge Amy M.
Published: March 2024

Although bereavement is an experience emerging adults of every culture go through, there is limited cross-cultural research on coping following bereavement. Therefore, this study aimed to explore similarities and differences between European American and Japanese emerging adults regarding their experiences with coping strategies following a death, with consideration of cultural rituals related to bereavement. Open-ended 30- to 50-min virtual interviews were conducted among 7 European American and 7 Japanese adults between the ages of 20–30 years old. Through qualitative analysis researchers found that for both cultures, reported characteristics of coping strategies typically aligned with conceptions of emotion engagement and emotion disengagement coping, as defined in Tobin’s Coping Strategies Inventory (2001). Both cultures reported similar coping strategies, although European Americans reported a greater variety of activities within the coping categories. Some coping behaviors could not be categorized under either coping strategy, implying a need for more research and conceptual refinement.
Mutual learning through participatory storytelling: Creative approaches to climate adaptation education in secondary schools
Authors: Heinemeyer Catherine , Reason Matthew , Quatermass Natalie , Wood Natalie , Adekola Olalekan
Published: March 2024

Unprecedented global temperatures have brought the question of how to teach sensitive issues of climate change to the fore. In this paper we suggest that a refocusing on adaptation productively shifts the debate to climate justice and practical solutions to building community resilience. The paper examines a practice-led project that sought to innovate and test the use of participatory storytelling with young people to explore climate adaptation. Our insights relate to two areas: first, the benefits of mutual learning through engaging in dialogue with frontline communities; second, how participatory storytelling supports emotionally intelligent sensemaking, agency and leadership by providing both ‘connections’ and ‘containers’ for engaging with climate.
Experiences With Deportation and Mexican-Origin Fathers’ Parenting Practices and Stress
Authors: Gonzalez Henry
Published: March 2024

For many Mexican-origin families in the U.S., a deportation can be a familiar sighting. Threats of deportation can infringe on parent-child bonds and the activities parents are able to participate in with their children. Using data from a community sample of 85 Mexican-origin fathers, this study utilized a culturally adapted family stress model to examine the role of fathers’ experiences with deportation in undermining positive parenting practices and heightening parenting stress, and then test whether fathers’ perceived access to informal social support moderates these associations. Multiple regression analyses showed the complexity of the role of social support in family stress processes. Findings suggest fewer positive parenting practices were reported by fathers with more deportation experiences, but only in conditions where fathers perceived lower-than-average social support. Also, fathers perceiving higher-than-average social support reported parenting stress if they were also experiencing greater depressive symptoms. Practical implications of state-sanctioned family separations are discussed.
Diverse Early-Life Family Trajectories and Young Children’s Mental Health in the UK

Past research suggests that children from two-parent married families fare better than children from other families on many outcomes. Only fragmented evidence on diverse family trajectories in association with child mental health is available. Using multi-channel sequence analysis and data from the UK Household Longitudinal Study, we jointly capture maternal partnership trajectories and type of father co-residence between birth and age 5. We then assess the association between these family trajectories and child mental health at age 5 and 8 using random effects regression. Children whose trajectories include the entrance of a non-biological father or parental separation have the lowest levels of mental health. However, children of never partnered mothers and those who repartner with the biological father have comparable mental health to children of stably married biological parents. Thus, not all types of family complexity or instability appear to be equally detrimental to children’s mental health.
Moral and ethical values in structural patterns of coercive acts in Hebrew Bible narrative
Authors: Sharon Diane M.
Published: March 2024

There are many biblical episodes in which people are compelled by an explicit or implicit threat of force, which is one definition of coercion, yet the issue of coercion has not yet been systematically explored for Hebrew Bible narrative. Examining the phenomenon of coercion across biblical narrative, this study asks how coercion is viewed and valued in the Hebrew Bible, what determines whether coercion is punished or rewarded, and what the theological significance is of this judgment.
Narratological implications of the differences between the Masoretic Text and the Septuagint: 1 Samuel 10.5 and 13.1–4 as a case study
Authors: D’Amico Davide
Published: March 2024

This article illustrates the importance of considering the narratological implications of textual variations in the Septuagint, the Greek translation of the Hebrew Bible. While these differences have traditionally concerned textual critics, this study argues for their importance in the field of narrative analysis as well. Using the divergent readings in 1 Samuel 10.5 and 1 Sam. 13.1–4 as a case study, the article analyzes the potential meaning and implications of these textual variants by showing how the different readings can offer new perspectives and uncharted avenues of interpretation, expanding our understanding of the Greek text as a distinct literary work. By bridging textual criticism and narrative analysis, this article aims to contribute to a deeper appreciation of the narratological dimensions inherent in the Septuagint and highlight its significance in the broader field of biblical narratology.

Published: March 2024

The bond property between glass fiber reinforced polymer (GFRP) bars and concrete under repeated loading is critical in determining the suitability of GFRP bars for marine engineering. This study investigates the bond strength and slip between GFRP bars and marine concrete under repeated loads using a beam-type test. The 16 groups of beam specimens are fabricated, and 50 repeated loads are applied to them. The influences of loading level and loading times on bond strength, slip process, slippage, and residual slippage are analyzed. The loss rate of bond strength exceeds 50%, and irrecoverable cracks in the steel hinge of beam specimens are observed when the repeated load level is 65% of the ultimate load. The slippages rise as the loading level increases. When the number of repeated loadings reaches about 8, the slippage is 50% of the entire slippage, and then the slip difference gradually decreases, and slippages no longer increase. Residual slippages increase with the loading level, but they increase initially and then stabilize with the loading times. The fitting curves agree well with the experimental results, indicating that they could be employed to describe the bond property of GFRP bars in marine concrete under repeated loading.
Perfectionism, Feelings of Not Mattering, and Suicide Ideation: An Integrated Test of the Perfectionism Social Disconnection Model and the Existential Model of Perfectionism

The Perfectionism Social Disconnection Model (PSDM) and the Existential Model of Perfectionism and Depressive Symptoms (EMPDS) are promising models of perfectionism and psychopathology. However, research examining suicide ideation within the PSDM is scarce, and no research has examined suicide ideation as an outcome in the EMPDS. Moreover, tests of the PSDM and EMPDS have been conducted separately and most research has examined the PSDM and EMPDS using cross-sectional or two-wave longitudinal designs, which do not provide a satisfactory test of mediation. In the current study, we addressed these limitations by testing whether perfectionism confers vulnerability to suicide ideation via feelings of mattering and anti-mattering (from the PSDM) and via difficulty accepting the past (from the EMPDS) in a three-wave longitudinal design in two independent samples of undergraduate students and community adults. Participants completed measures on three occasions over 6 weeks. Findings revealed that socially prescribed perfectionism indirectly predicted suicide ideation via difficulty accepting the past in both samples. In addition, in the undergraduate sample only, socially prescribed perfectionism indirectly predicted higher suicide ideation via anti-mattering, and self-oriented perfectionism indirectly predicted higher suicide ideation via mattering. Based on our findings, we advocate for future research to include suicide ideation in the PSDM and EMPDS, to integrate explanatory models, and to examine a mattering-specific EMPDS.
