Suzane is The New Black
Authors: Brasiliense Danielle
Published: January 2025

Neste artigo vamos falar sobre a exploração midiática do fait-divers através das histórias narrativas da presidiária Suzane, visto que, ela é a representação social no Brasil do que conhecemos como monstruoso, alguém que cometeu grande atrocidade contra o pilar da ordem social, a família. Ainda que vista como monstro desde seu ato assassino repousa sobre ela um mecanismo eficaz de manutenção da emoção e respiração do público de massa que acompanha seu caso sempre em alta tensão. Assim como nas séries de TV, especialmente em Orange Is The New Black, com as narrativas sobre presidiárias, Suzane segue o seu percurso como num romance folhetinesco vivo e seriado, que ronda os discursos midiáticos e que por sua vez, sempre deixam a história inacabada com a espera de um novo número, uma nova edição, que não deixa morrer a curiosidade do seu público.
Do anonimato à fama: processos de celebrização no funk ostentação
Authors: Pereira Simone Luci , Silva Maria Fernanda Andrade da
Published: January 2025

Este artigo aborda os processos de celebrização envolvidos na passagem de jovens comuns da periferia de São Paulo a ídolos locais e até nacionais, como intérpretes do funk ostentação. A via principal desta alçada: a postagem de seus videoclipes na plataforma Youtube. Veremos como os MC´s, autores e intérpretes deste estilo recentemente se tornaram atores sociais em suas comunidades, contribuindo para que as representações que carregam sejam símbolos ou mercadorias e atuem como instrumentos de materialização dos imaginários. Ao final, apontamos para os sentidos ambíguos e contraditórios de resistência possíveis esboçados por este gênero musical e suas estéticas e valores, em bioresistências que passam pelos corpos e afetos.
Filhos desta luta: posicionando A produção do rock e do metal angolano no cenário global-local
Authors: Dos Santos Silva Melina Aparecida
Published: January 2025

O artigo reflete sobre a produção do gênero musical metal, após o fim da guerra civil angolana. Nesta conjuntura de reestruturação econômica, social e política, o acesso aos meios de produção fonográfica ainda consiste em um desafio para os integrantes do movimento musical. Para observar tais dinâmicas musicais, destaco que o gênero musical possui regras sonoras, como solos de guitarra, distorção e tempos rápidos, técnicas de canto como o gutural e vocais gritados; regras visuais, como o uso de vestuários como camisas de bandas ou os conceitos estéticos reproduzidos em capas de álbuns, e líricas, formas de circulação e de consumo, suas audiências, performances e respostas corporais. Para tanto, o artigo apresenta as peculiaridades desta cena musical através do método etnográfico, com trabalhos de campo realizados em períodos diferentes dos anos de 2014, 2016 e 2017.
De quem é a praça Gomes Freire?: As disputas simbólicas no espaço Jardim e as representações da imprensa de Mariana-MG
Authors: Coração Cláudio Rodrigues , Carneiro Filipe Davison Barboza
Published: January 2025

Principal espaço público de Mariana-MG, a praça Gomes Freire – mais conhecida como Jardim – é frequentada por diferentes grupos sociais. Essa sociabilidade não se dá de forma totalmente harmônica, o que gera disputas simbólicas. A partir do entendimento de que deve ser preservado no Jardim seu caráter plural de convivência – mesmo na chave da tensionalidade – este artigo pretende investigar as representações sobre a praça através da mídia local, mais precisamente pelo jornal Ponto Final, já que a imprensa é um dos principais agentes construtores dos sentidos urbanos. As análises mostram que, apesar da variada gama de uso, o jornal prefere dar destaque aos supostos aspectos negativos do Jardim. Dessa forma, é possível afirmar que as pautas jornalísticas batem com as ideias de higienização, controle e vigília, visão que pode interessar a determinados grupos e que coloca em risco o caráter estritamente público da praça.
Análise cultural-midiática no telejornalismo do Oeste Catarinense
Authors: Da Silva Franscesco Flávio , Lisboa Filho Flavi Ferreira
Published: January 2025

Este apresenta como dois telejornais de Chapecó – Santa Catarina, representam os sujeitos e suas interações da região Oeste do referido Estado em seus textos, contribuindo para (re)configurar uma identidade regional. A incidência da globalização no contexto histórico, político e cultural tornam a região uma zona de tensão identitária. Neste sentido, buscamos nos Estudos Culturais suporte teórico e metodológico para realizar uma análise cultural-midiática que desse conta do nosso propósito investigativo. Pudemos perceber a diferença das representações entre os telejornais, assim como a forte representação da região a partir de Chapecó e dos chapecoenses, assim como a presença de traços da cultura gaúcha contrastando com a exclusão de certos aspectos culturais de outras regiões do estado de Santa Catarina.
Invasores: classe, território e perspectiva no cinema brasileiro contemporâneo
Authors: Souto Mariana
Published: January 2025

Por meio de uma análise comparativa, este artigo investiga uma questão comum a cinco filmes brasileiros contemporâneos que tratam de relações entre classes sociais: o recurso do personagem invasor, figura que atua como elemento disparador dos conflitos da trama. Assumindo diferentes funções em Trabalhar cansa, Eles voltam, O som ao redor, Casa grande e Que horas ela volta?, a invasão, ao convocar noções espaciais, destaca a maneira como as relações de classe se apresentam fortemente territorializadas. O olhar desse corpo estranho possibilita uma posta em perspectiva – que aqui observamos criticamente por meio de um exame tanto de componentes dramáticos (personagens e intriga) como de outros mais propriamente estéticos (planos e enquadramentos).
Cidades, pornotopias e identificações estranhas em El Mendigo Chupapijas
Authors: Dos Santos Matheus Araujo
Published: January 2025

Neste artigo me aproximo dos problemas que emergem como consequência do cruzamento entre cidade, corpo e desejo. A partir de El Mendigo Chupapijas, autoficção publicada pelo argentino Pablo Pérez em 2005, apresento algumas questões sobre o espaço urbano e suas possibilidades de uso e profanação. O imaginário evocado pelo autor, cuja história descreve a Buenos Aires dos anos de 1990, apresenta-nos uma cidade cuja arquitetura é atravessada por prazeres subterrâneos que, como discutimos, são capazes de nos sugerir outros modos de habitá-la.
Como o jornalismo literário aliado ao jornalismo científico pode potencializar a divulgação da ciência
Authors: Fontes Henrique Rodrigues
Published: January 2025

Diante da crise que afeta a ciência nacional, a divulgação científica emerge como uma alternativa para reiterar a indiscutível importância das pesquisas para a sociedade. Nesse sentido, o Jornalismo Literário (JL), através de suas técnicas, pode ser utilizado como uma importante ferramenta para atrair os mais diversos leitores ao universo científico. Por isso, o objetivo deste artigo foi estudar, por meio de revisão bibliográfica e de três entrevistas com especialistas, como o JL, aliado ao Jornalismo Científico, pode contribuir para aumentar o interesse e o entendimento da sociedade sobre a ciência no Brasil. No trabalho, foi observado que o JL atua com grande eficiência para tornar a ciência mais atraente aos olhos de quem ainda se encontra distante de seu mundo, colaborando para aproximar o leitor comum de temas considerados mais complexos, mas extremamente relevantes ao público em geral.

Batalhas sônicas: disputas territoriais do Congo Capixaba
Authors: Madeira Thaíse Valentim , Marra Pedro Silva
Published: January 2025

Este artigo se propõe a refletir sobre as disputas territoriais agenciadas por meio de campanhas sônicas realizadas durantes as festas do Congo Capixaba. Trata-se de entender a convergência das dimensões cognitivas e somáticas dos sons, a partir da análise dos processos comunicativos, sociais e culturais gerados em experiências sonoras possíveis durante as festas em questão. Para tanto, examina-se as dinâmicas de colonização sonora em situações de conflitos sugeridas a partir do modelo tripartite de Daughtry (2015) - Regimes Auditivos, Campanhas Sônicas e Territórios Acústicos.  Acredita-se que, no contexto das festas, os parâmetros acústicos (intensidade, frequência e espacialidade), e o e o trânsito espacial e simbólico das manifestações convergem na enunciação e territorialização de suas tradições ancestrais no cenário contemporâneo.
A atuação da mídia em processos de gentrificação: um estudo sobre o Morro Santa Terezinha, em Fortaleza, Brasil
Authors: Belmino Sílvia Helena , Amaral João flávio Menezes
Published: January 2025

Este artigo analisa a relação entre a gentrificação do Morro Santa Terezinha, comunidade de pescadores em área turística de Fortaleza e as matérias veiculadas no Jornal Diário do Nordeste entre 1982 e 1995. Com os trabalhos de Pereira, Wacquant e Slater (2014) sobre a relação de estigmas territoriais e a teoria do deslocamento de renda de Smith (1982), de Thompson (2014) sobre ideologia e mídia, e de Lefebvre (1991) e Haesbaert (2004) observou-se uma dimensão simbólica nos processos de gentrificação.  Analisou-se 04 matérias com base nos Modos de Operação Ideológicos de Thompson (2007). Concluiu-se que o jornalismo atua como agente em processos de gentrificação por meio da enunciação de discursos que reproduzem, legitimam ou dissimulam relações e estruturas de poder que estão no centro das dinâmicas de territorialização intra-urbanas. Palavras Chave: Gentrificação, Ideologia, Jornalismo

Uma abordagem investigativa para o estudo da elasticidade
Authors: De Mesquita Diles Saulo
Published: January 2025

Este trabalho apresenta uma proposta de atividade investigativa o ensino da força elástica. A ideia é utilizar as tão populares ligas de borracha no ensino de Física na educação básica, fazendo com que os estudantes experimentem na prática as propriedades de elasticidade e a os efeitos da força elástica. Os estudantes irão "brincar" de disparar a liga elástica e toda esta dinâmica será vista como um procedimento experimental onde os estudantes, em equipes, buscam formas de executar o experimento e medir as grandezas físicas a ele associados. A proposta é detalhada desde a sua concepção teórica, seus materiais e métodos, o papel do professor como coordenador da atividade e o papel dos estudantes como atores protagonistas do processo. Também são discutidas alternativas que viabilizem a execução da proposta diante de situações adversas como escassez de recursos de custeio.

We characterize a large-aperture gas-cooled Faraday rotator (FR) designed to mitigate stress-induced depolarization in high-energy, high-power laser systems. The rotator, based on ceramic TGG, was tested using a 150 mW probe beam at 1047 nm and a pump beam at 1070 nm. Compensating for the birefringence induced by the surrogate depolarization plate at 3.3 kW of effective pump power, the rotator reduces the spatially in-homogeneous depolarized light containing linear, circular, and elliptical polarization states to nearly linear with approximately 0.8% (or −21 dB) of residual depolarized energy. The FR demonstrated effective depolarization compensation across its 58×58 mm2 aperture.
The calcitron: A simple neuron model that implements many learning rules via the calcium control hypothesis
Authors: Moldwin Toviah , Azran Li Shay , Segev Idan
Published: January 2025

Theoretical neuroscientists and machine learning researchers have proposed a variety of learning rules to enable artificial neural networks to effectively perform both supervised and unsupervised learning tasks. It is not always clear, however, how these theoretically-derived rules relate to biological mechanisms of plasticity in the brain, or how these different rules might be mechanistically implemented in different contexts and brain regions. This study shows that the calcium control hypothesis, which relates synaptic plasticity in the brain to the calcium concentration ([Ca2+]) in dendritic spines, can produce a diverse array of learning rules. We propose a simple, perceptron-like neuron model, the calcitron, that has four sources of [Ca2+]: local (following the activation of an excitatory synapse and confined to that synapse), heterosynaptic (resulting from the activity of other synapses), postsynaptic spike-dependent, and supervisor-dependent. We demonstrate that by modulating the plasticity thresholds and calcium influx from each calcium source, we can reproduce a wide range of learning and plasticity protocols, such as Hebbian and anti-Hebbian learning, frequency-dependent plasticity, and unsupervised recognition of frequently repeating input patterns. Moreover, by devising simple neural circuits to provide supervisory signals, we show how the calcitron can implement homeostatic plasticity, perceptron learning, and BTSP-inspired one-shot learning. Our study bridges the gap between theoretical learning algorithms and their biological counterparts, not only replicating established learning paradigms but also introducing novel rules.
Who talks about climate, peace and security? A social media analysis to identify key global actors
Authors: Tucci Giulia , Carneiro Bia , Caroli Giulia , Pacillo Grazia
Published: January 2025

Uncovering key actors within a policy network provides pathways for engagement, consensus-building, partnership development, and understanding the diffusion of knowledge in a given debate. Given the unprecedented scale of the climate emergency, the emerging field of climate security has rapidly gained centrality in academic and policy fora, as well as in the public debate. Yet, a systematic analysis of the main actors engaged in this space is missing. This study draws from digital methods and network analysis techniques to employ a method for identifying relevant actors, focusing on Twitter (now X) from 2014 to 2022, with the objective of systematically spotting the major actors driving and shaping public discussions around climate security. The research also demonstrates how institutions can position themselves within such issue networks through a case study of the CGIAR, the largest publicly funded global research partnership for a food-secure future dedicated to transforming food, land, and water systems in a climate crisis that has recently positioned itself in this community. Results reveal that the climate security debate on social media is predominantly institutional, with research bodies and international organizations from the Global North as central elements. While CGIAR is a relatively new actor, it is already centrally located in the network, maintaining strong connections with other major players, which places it in a strategic position to enhance its influence and reach. Understanding this discursive landscape is crucial for institutions and organizations to identify opportunities for effective engagement, partnership, and positioning in such an increasingly salient field of research and practice.
Effects of intrathecal administration of sodium nitroprusside and nicardipine on cerebral pial microcirculation, cortical tissue oxygenation, and electrocortical activity in the early post-resuscitation period in a porcine cardiac arrest model

Published: January 2025

Recent studies suggested intrathecal vasodilator administration as a therapy to mitigate post-ischemic cerebral hypoperfusion following cardiac arrest. We examined the effects of two commonly used intrathecal vasodilators, sodium nitroprusside (SNP) and nicardipine, on cerebral pial microcirculation, cortical tissue oxygen tension (PctO2), and electrocortical activity in the early post-resuscitation period using a porcine model of cardiac arrest. Thirty pigs were resuscitated after 14 min of untreated cardiac arrest. At 30 min after resuscitation from cardiac arrest, 30 pigs randomly received 4 mg of SNP, 4 mg of nicardipine, or saline placebo via subdural intracranial catheters and were observed for 5 h. Group effect and group-time interaction were assessed using linear mixed-effects models. The mean arterial pressure was lower in the nicardipine group (coefficient [95% confidence interval {CI}], -15.824 [-24.082 to -7.566]) and higher in the SNP group (coefficient [95%CI], 11.232 [2.974–19.490]) compared to the saline group. The percentage of pial arteriole diameter relative to the pre-arrest baseline value (coefficient [95% CI], 48.970 [13.884–84.057]), microvascular flow index (coefficient [95% CI], 0.296 [0.071–0.521]), and PctO2 (coefficient [95% CI], 26.926 [12.404–41.449]) were higher in the SNP group but not in the nicardipine group compared to the saline group. Amplitude-integrated electroencephalography amplitude recovery was faster in the SNP group (coefficient [95% CI], 1.149 [0.468–1.829]) but not in the nicardipine group compared to the saline group. In conclusion, intrathecal SNP but not nicardipine was effective in treating post-ischemic cerebral hypoperfusion after cardiac arrest.

The emergence of Next Generation Sequencing (NGS) technology has catalyzed a paradigm shift in clinical diagnostics and personalized medicine, enabling unprecedented access to high-throughput microbiome data. However, the inherent high dimensionality, noise, and variability of microbiome data present substantial obstacles to conventional statistical methods and machine learning techniques. Even the promising deep learning (DL) methods are not immune to these challenges. This paper introduces a novel feature engineering method that circumvents these limitations by amalgamating two feature sets derived from input data to generate a new dataset, which is then subjected to feature selection. This innovative approach markedly enhances the Area Under the Curve (AUC) performance of the Deep Neural Network (DNN) algorithm in colorectal cancer (CRC) detection using gut microbiome data, elevating it from 0.800 to 0.923. The proposed method constitutes a significant advancement in the field, providing a robust solution to the intricacies of microbiome data analysis and amplifying the potential of DL methods in disease detection.
“I sometimes feel like I can’t win!”: An exploratory mixed-methods study of women’s body image and experiences of exercising in gym settings
Authors: Cowley Emma S. , Schneider Jekaterina
Published: January 2025

Despite an increase in gym memberships, women are less active than men and little is known about the barriers women face when navigating gym spaces. This study explored women’s body image and experiences exercising in gyms. Two-hundred and seventy-nine women (84% current gym-goers; 68.1% White) completed an online mixed-methods survey. Thematic analysis of qualitative data produced four themes and nine subthemes: (1) “Never enough” ([perceived] judgement about appearance, [perceived] judgement about performance); (2) “Often too much” (self-criticism, clothing challenges); (3) “Always on display” (harassment and safety, fighting for space, the appearance contingency); and (4) “Sometimes empowered” (empowering places, empowering self). Qualitative and quantitative data showed that women often feel judged for their appearance and performance, leading to a persistent sense of inadequacy, as well as having to fight for space in the gym and to be taken seriously, while navigating harassment and unsolicited comments from men. Despite this, women showed signs of resistance towards gendered and appearance ideals permeating gym environments and some experienced empowerment through skill acquisition, breaking gender norms, and exercising in supportive environments. Based on our findings, we suggest a multi-level approach to tackling these barriers and creating more inclusive gym spaces for women.

Many HIV clinics with poor IT-infrastructure are unable to report data on individuals in care with HIV, on antiretroviral treatment (ART) and virologically suppressed (VS), with the aim of monitoring the HIV Continuum of Care to estimate efficacy of HIV treatment programmes. We developed an estimation-tool, ESTIHIV, and determined the minimal data required for a random sample, to produce representative estimates, with a specified level of precision, of people with HIV on ART and VS. For proof of concept, 8852 HIV positive persons from seven clinics in seven different countries, with a follow-up visit during 2017, were included. Of those, 93.8% were on ART (95% CI 93.3–94.2) and 76.7% were VS (95% CI 75.8–77.6). In 2022, we tested the tool in the RESPOND Cohort for all countries with more than 100 participants under follow-up in 2019. We included 26,426 HIV positive persons from clinics in 27 countries, 97.8% (95% CI 97.6-98.0) were on ART and 91.5% were VS (95% CI 91.2-91.8%). There was good agreement between the RESPOND country estimates of ART and VS and the estimations using a random sample calculated in ESTIHIV. With ESTIHIV, clinics can produce a reliable estimate in figures for reporting and for monitoring the effectiveness of care in their clinics.
Joint trajectories of physical activity, health, and income before and after statutory retirement: A 22-year follow-up
Authors: Lallukka Tea , Kolmonen Petteri , Rahkonen Ossi , Lahelma Eero , Lahti Jouni
Published: January 2025

Background

Health behaviors, health, and income change during aging. However, no previous studies have examined, how they develop together over the transition to statutory retirement. We aimed to examine their joint development and to identify the determinants of any distinct trajectories.

Methods

We studied former employees of the City of Helsinki, Finland, who transitioned to full statutory retirement between 2000 and 2022 (n = 5209, 80% women). We examined five repeated questionnaire surveys to identify any joint developmental patterns in the key indicators of healthy aging and well-being—leisure-time physical activity, health measured by general health perceptions, and household income, over a follow-up of 22 years. We used joint group-based trajectory analysis to identify latent developmental groups. The social and health-related determinants of trajectory group membership are reported as average marginal effects.

Results

We found four distinct joint trajectory groups. Group 1 (22.6%) had consistently poor general health perceptions, less physical activity than the recommended amount, and low income. In Group 2 (34.2%), general health perceptions were first good but then declined, and income was low but slightly increasing. Group 3 (12.3%) had good general health perceptions, a very high level of physical activity, but fluctuating income. In Group 4 (30.9%), general health perceptions were first good but then declined, physical activity was at the recommended level, and income was sharply increasing. People with obesity had a 22 percentage-point (21–24) higher predicted probability of belonging to Group 1 than people with normal weight. They were also more likely to report low education and more physician-diagnosed chronic diseases and mental disorders.

Conclusions

We identified distinct trajectories in physical activity, general health perceptions, and income over a follow-up of over 20 years. The majority of those who had transitioned to statutory retirement had good general health perceptions but varying levels of physical activity and income. As not all those with a low income had a low level of physical activity or poor general health perceptions, public health interventions should target distinct groups with the most adverse risk factor profiles, to narrow health inequalities during aging.
Adaptive weighted progressive iterative approximation based on coordinate decomposition
Authors: Liu Yushi , Wang Yan , Liu Chengzhi
Published: January 2025

During the iterative process of the progressive iterative approximation, it is necessary to calculate the difference between the current interpolation curve and the corresponding data points, known as the adjustment vector. To achieve more precise adjustments of control points, this paper decomposes the adjustment vector into its coordinate components and introduces a weight for each component. By dynamically adjusting these weights, we can accelerate the convergence of iterations and enhance approximation accuracy. During the iteration, the weight coefficients are flexibly adjusted based on the error of the current iteration step, demonstrating the flexibility and precision of the geometric iterative method in addressing geometric approximation problems. Numerical experiment results indicate that this vector decomposition technique is a critical mathematical operation for improving algorithm efficiency and precisely adjusting the shapes of curves or surfaces to approximate the data set.
Study on the impact of Kinesiophobia after Total Knee Arthroplasty on the rehabilitation of patients during hospitalization: A pilot study
Authors: Yao Yichao , Zhang Qi , Cui Shaoning , Guo Xumeng
Published: January 2025

The purpose of this study is to investigate the influence of kinesiophobia following Total Knee Arthroplasty (TKA) on the rehabilitation outcomes of patients during hospitalization, includes examining the trends in resting pain levels at various time points post-surgery, the trends in active flexion of the knee at various time points post-surgery, and the effects of kinesiophobia on the timing of first postoperative ambulation, the duration of postoperative hospital stay, and the results of the two-minute walk test on the day of discharge. Postoperative kinesiophobia in patients was identified using the Tampa Scale for Kinesiophobia (TSK), with 33 patients scoring >37 points and 35 patients scoring ≤37 points. Resting Pain levels were assessed using the Numerical Rating Scale (NRS) at various time points, including upon return to the ward (T1), the first (T2), second (T3), third (T4), fifth(T5) postoperative days, and the day of discharge (T6). Furthermore, active flexion of the knee joint was measured at different time points for both groups, including the first (T1*), third (T2*), and fifth (T3*) postoperative days, and the day of discharge (T4*). The first time out of bed activities of the two groups of patients were compared, along with the results of the 2-Minute Walk Test (2-MWT) on the day of discharge. The pain scores of patients in the kinesiophobia group at different time points after surgery were worse than those in the non-kinesiophobia group (P<0.05). There were significant time effects (F = 131.297;P<0.01), inter-group effects (F = 15.016; P<0.01), and interaction effects (F = 5.116; P<0.05). The active knee flexion of patients in the kinesiophobia group at different time points after surgery were worse than those in the non-kinesiophobia group (P<0.05).There were significant time effects (F = 628.258;P<0.01), inter-group effects (F = 16.546; P<0.01), and interaction effects (F = 66.025; P<0.01). Patients in the kinesiophobia group delayed getting out of bed for the first time (35.39±9.82vs28.77±9.81hours; P<0.01), had shorter activity time (4.12±1.36vs5.80±1.96minutes; P<0.01) and distance (19.12±3.36vs30.17±5.64meters;P<0.01), and experienced higher pain scores during activity (6.30±1.10vs5.48±0.95scoresP<0.05). Additionally, patients in the kinesiophobia group walked shorter distances in the 2-MWT test on the day of discharge compared to the non-kinesiophobia group (37.60±5.76vs50.68±5.37meters;P<0.05), and had longer hospitalization time (8.11±1.31vs50.68±5.37days; P<0.05). In short, compared to patients without kinesiophobia, the presence of kinesiophobia after TKA surgery significantly impacts the efficacy of early rehabilitation exercises during hospitalization. This impact is observed in pain perception, knee joint mobility, the 2-minute walk test, etc. Early identification of patients with kinesiophobia after TKA and timely intervention are necessary and beneficial.
Comparative analysis of antibiotic resistance genes between fresh pig manure and composted pig manure in winter, China
Authors: Huang Shuai , Xing Minghui , Wang Haifeng
Published: January 2025

Antibiotic resistance is a critical global public health issue. The gut microbiome acts as a reservoir for numerous antibiotic resistance genes (ARGs), which influence both existing and future microbial populations within a community or ecosystem. However, the differences in ARG expression between fresh and composted feces remain poorly understood. In this study, we collected eight samples from a farm in Kaifeng City, China, comprising both fresh and composted pig manure. Using a high-throughput quantitative PCR array, we analyzed differences in ARG expression between these two types of manure. Our findings revealed significant differences in ARG profiles, as demonstrated by principal coordinate analysis (PCoA). Further analysis identified 39 ARGs (log2FC > 1, p < 0.05) in composted pig manure, with 25 genes downregulated and 14 upregulated. Notably, tetB-01, blaOCH, and blaOXY were the most abundant in composted pig manure compared to fresh manure. Additionally, 16S rRNA species profiling revealed that the composting process significantly altered the microbial community structure, with an increased abundance of Firmicutes and a decreased abundance of Bacteroidetes in composted pig manure. In summary, composting substantially transforms both the microbial community structure and the ARG profile in pig manure, underscoring its potential role in modulating the dynamics of ARGs in agricultural environments.
Brief social presence improves delayed memory for online lecture content
Authors: Santacroce Lindsay A. , Appiah Rachel , Sullivan Margot D. , Spaniol Julia
Published: January 2025

During the COVID-19 pandemic, the use of videoconferencing platforms became ubiquitous in postsecondary education around the world, making it crucial to understand how to maximize the efficacy of synchronous online classes. Given that social information can act as a motivation and improve memory, the current study tested the hypothesis that brief social presence during an online class would act as a social reward that would increase delayed memory for lecture information. Undergraduate students attended a mock synchronous class during which they viewed a pre-recorded science lecture, and social presence was manipulated by having participants turn on their cameras before and after the lecture (high social presence) or having cameras remain off during the entire class (low social presence). After 24 hours, participants completed a surprise memory test for the lecture material and a subjective experience survey about the class. As predicted, participants in the high social presence condition demonstrated higher recognition memory for the lecture content and gave higher ratings of enjoyment and feeling part of a group compared to participants in the low social presence condition. These findings suggest that enhancing social presence in virtual environments may be leveraged to boost academic performance in university students.

Insecticide resistance is a major problem in food production, environmental sustainability, and human health. The cotton bollworm Helicoverpa armigera is a globally distributed crop pest affecting over 300 crop species. H. armigera has rapidly evolved insecticide resistance, making it one of the most damaging pests worldwide. Understanding the genetic basis of insecticide resistance provides insights to develop tools, such as molecular markers, that can be used to slow or prevent the evolution of resistance. We explore the genetic architecture of H. armigera resistance to a widely used insecticide, flubendiamide, using two complementary approaches: genome-wide association studies (GWAS) in wild-caught samples and quantitative trait locus (QTL) mapping in a controlled cross of susceptible and resistant laboratory strains. Both approaches identified one locus on chromosome 2, revealing two SNPs within 976 bp that can be used to monitor field resistance to flubendiamide. This was the only region identified using linkage mapping, though GWAS revealed additional sites associated with resistance. Other loci identified by GWAS in field populations contained known insecticide detoxification genes from the ATP-binding cassette family, ABCA1, ABCA3, ABCF2 and MDR1. Our findings revealed an oligogenic genetic architecture, contrasting previous reports of monogenic resistance associated with the ryanodine receptor. This work elucidates the genetic basis of rapidly evolving insecticide resistance and will contribute to developing effective insecticide resistance management strategies.

Hepatocellular carcinoma(HCC) has a high mortality and morbidity rate and seriously jeopardizes human life. Chemicals and chemotherapeutic agents have been experiencing problems such as side effects and drug resistance in the treatment of HCC, which cannot meet the needs of clinical treatment. Therefore, finding novel low-toxicity and high-efficiency anti-hepatocellular carcinoma drugs and exploring their mechanisms of action have become the current problems to be solved in the treatment of HCC. Several studies have reported anticancer effects of inotodiol. This study focuses on the anticancer effect of inotodiol in HCC cells and its molecular mechanism, aiming to explore its anticancer effect in depth. The CCK8 assay was utilized to assess cell viability, the scratch assay was utilized to detect migration ability, the clone formation assay was utilized to detect clonogenic ability, and flow cytometry was utilized to analyze apoptosis and cell cycle. Animal experiments was utilized to verify the inhibitory effect of inotodiol on HCC. Meanwhile, western blotting was utilized to detect proteins associated with apoptosis, cell cycle and MAPK/ERK pathway. These results showed that inotodiol has the ability to promote apoptosis, as well as inhibit the ability of cell proliferation, migration, and clonogenic ability. The cell cycle was arrested in G1 phase, when the expression of CDK2, CDK4, CDK6 and Cyclin D were inhibited. In addition, inotodiol showed to induce apoptosis, characterized by an increase in Bax expression, a decrease in Bcl-2, Bcl-XL and MCL1 expression, the initiation of cleaved PARP1 and cleaved caspase 3, and inhibition of the MAPK/ERK pathway. Animal studies demonstrated that inotodiol possessed the ability to suppress tumor growth in nude mice models, at the same time, there was no significant impact on the body weight and organs of the mice. In conclusion, the findings presented herein compellingly suggest that inotodiol may serve as a promising candidate for the treatment of hepatocellular carcinoma (HCC).
The effect of physical exercise and cognition-orientated interventions on post-stroke cognitive function: Protocol for an overview of reviews
Authors: Smith James , Nagy Philip , Tod David , Holland Carol , Jarvis Hannah
Published: January 2025

Background

Strokes are becoming more common, and with improving survival rates, the prevalence of stroke survivors has increased. Almost half of chronic stroke survivors are cognitively impaired, and healthcare services are struggling to manage these patients, leaving some feeling “abandoned”. Several systematic reviews have investigated the effect of physical exercise and cognition-orientated interventions on post-stroke cognitive impairment, and have produced conflicting findings, making it difficult for clinicians and guideline producers to make evidence-based decisions. This overview of reviews aims to provide a comprehensive overview of systematic reviews investigating the effect of physical exercise and cognition-orientated interventions on post-stroke cognitive function, assess methodological quality and certainty of evidence, and identify sources of discordance between these reviews.

Methods

Eight databases–Embase, Medline, CINAHL, Psycinfo, SPORTDiscus, The Cochrane Database of Systematic reviews, Epistemonikos, and Scopus–plus grey literature sources will be searched. The eligibility criteria include systematic reviews of trials that included an adult stroke population and investigated physical exercise and/or cognition-orientated interventions. Only reviews that assessed at least one of the DSM-5 neurocognitive domains will be included. Screening, data extraction, and quality appraisal will be conducted by two independent reviewers. Methodological quality, certainty of evidence, and primary study overlap will be assessed using the AMSTAR-2, GRADE, and GROOVE tools, respectively. Interventions will be grouped into exercise, cognition-orientated, and combined interventions, and findings will be synthesised narratively. Heterogeneity assessment will be conducted to identify factors causing discordance between reviews.

Discussion

The findings of this overview will allow decision makers to make evidence-based decisions, stratified by methodological quality and certainty of evidence. Heterogeneity assessment may identify factors causing discordance between systematic reviews, which could inform the design of future studies.

The processes and challenges in achieving uniformity of vowels and diction in Thai choral singing: A case study of Suanplu Chorus
Authors: Laovanich Vitchatalum , Laovanich Monsikarn
Published: January 2025

This research article explores the challenges faced in achieving uniformity of vowels and diction in Thai choral singing and investigates the process to create such uniformity. Using a qualitative approach, the study focuses on Suanplu Chorus, an award-winning choir, as a case study to understand the problems and the process involved. The findings reveal four main issues hindering the creation of uniformity: varying levels of understanding of the blending concept, differences in vocal placement and register selection, the complexity of Thai language and pronunciation, and the lack of standardization in Thai pronunciation and notation for singing. To address these challenges, the study proposes a two-fold process. Firstly, fostering blending and disciplined singing is essential to ensure consistent vocalization. Secondly, establishing guidelines to resolve the issue of unequal vocalization of vowel and consonant sounds is crucial. This research contributes to the understanding of the specific challenges faced in Thai choral singing and provides insights for choral directors and educators to use in developing strategies and guidelines for achieving uniformity of vowels and diction in Thai choral performances.

‘In her hips there’s revolution’: Kathy Acker’s post-situationist punk avant-garde
Authors: Horton Joshua T.
Published: January 2025

Kathy Acker is famous for her experimental and pornographic writing style, but she is infamous for violating one of the publishing industry’s most sacred taboos: plagiarizing and appropriating others’ works. While critics and theorists have been captivated by this practice, whether positively or otherwise, few have attributed this to Acker’s connection to punk and its DIY publishing praxes. This article moves beyond these critiques and situates Acker’s writing within a larger practice of a punk avant-gardism whose lineage can be traced to punk-adjacent leftist groups like UAW/MF, MC5 and the Situationists. In combatting what Guy Debord calls the spectacle, one strategy the Situationists used is détournement, or the rendering of familiar images as unfamiliar, forcing the viewer into the moment. Jamie Reid famously used this technique on Sex Pistols’s album covers, explicitly connecting punk signifiers with the Situationists. Through critical examination of Acker’s novel Blood and Guts in High School, I will demonstrate that Acker’s appropriation and hijacking of other authors’ works function not strictly as plagiarism but as a punk avant-garde literary détournement, aimed at subverting the capitalist and patriarchal mass publishing industry and reclaiming women’s narratives.

Green Trade Opportunities in Agriculture and Forestry for the Commonwealth Countries
Authors: Othieno Lawrence
Published: January 2025

Transitioning to green trade is a matter of urgency, given the drastic impacts of the climate crisis in several countries across the Commonwealth and world over. These impacts have proved a serious challenge to sustainable development. The climate crisis is reshaping countries’ economic and trade prospects, posing a major threat to human survival, future economic growth, and prosperity, especially for countries with high export concentrations in a range of climate-sensitive sectors, such as agriculture, fisheries, and tourism. If not countered, the crisis is likely to significantly destroy the trading capacity and export competitiveness of least developed countries (LDCs) and of small and vulnerable island countries. Urgent actions and supportive measures on adaptation and mitigation are needed to address the increasing risks and challenges the crisis poses.

Authors: de Klerk Kyle , Balchin Neil , Zhuawu Collin
Published: January 2025

This paper, the first of a two-part series, examines the renewable energy landscape in least developed countries (LDCs) and explores the scope to expand renewable energy generation and trade in these countries by maximising the potential of their renewable energy endowments. It begins with a detailed overview of existing renewable energy generation capacity across the group of LDCs, paying particular attention to Commonwealth LDC solar, wind, hydro and bioenergy generation. Thereafter, Section 3 examines the state of energy trade involving Commonwealth LDCs and explores opportunities for them to increase their exports of renewable energy. Section 4 assesses the renewable energy generation potential in LDCs through an analysis of their raw solar and wind resource endowments. The paper concludes by highlighting practical considerations for LDCs to accelerate their renewable energy transitions and maximise the trade, growth and economic development potential of their renewable energy resource endowments.
