Published: April 2024

Radiofrequency ablation (RFA) using the CARTO 3D mapping system is a common approach for pulmonary vein isolation to treat atrial fibrillation (AF). Linkage between CARTO procedural data and patients’ electronical health records (EHR) provides an opportunity to identify the ablation-related parameters that would predict AF recurrence. The objective of this study is to assess the incremental accuracy of RFA procedural data to predict post-ablation AF recurrence using machine learning model. Procedural data generated during RFA procedure were downloaded from CARTONET and linked to deidentified Mercy Health EHR data. Data were divided into train (70%) and test (30%) data for model development and validation. Automate machine learning (AutoML) was used to predict 1 year AF recurrence, defined as a composite of repeat ablation, electrical cardioversion, and AF hospitalization. At first, AutoML model only included Patients’ demographic and clinical characteristics. Second, an AutoML model with procedural variables and demographical/clinical variables was developed. Area under receiver operating characteristic curve (AUROC) and net reclassification improvement (NRI) were used to compare model performances using test data. Among 306 patients, 67 (21.9%) patients experienced 1-year AF recurrence. AUROC increased from 0.66 to 0.78 after adding procedural data in the AutoML model based on test data. For patients with AF recurrence, NRI was 32% for model with procedural data. Nine of 10 important predictive features were CARTO procedural data. From CARTO procedural data, patients with lower contact force in right inferior site, long ablation duration, and low number of left inferior and right roof lesions had a higher risk of AF recurrence. Patients with persistent AF were more likely to have AF recurrence. The machine learning model with procedural data better predicted 1-year AF recurrence than the model without procedural data. The model could be used for identification of patients with high risk of AF recurrence post ablation.

Published: April 2024

The popularity of martial arts in the present times has become apparent, therefore, it is necessary to explore martial artists’ preferences and the schools’ competitiveness. The purpose of this study was to assess martial artists’ preferences concerning the services offered by martial arts schools. Conjoint analysis was utilized to analyze the responses of fifty-five (55) martial artists based on the seven (7) martial arts schools’ attributes. The results showed that the type of martial arts was found to be the most important attribute (30.449%) followed by distance (27.970%), price range (22.706%), social environment (11.097%), class preference (5.080%), goal (1.562%), and schedule (1.135%). Furthermore, Muay Thai or Kickboxing was the most preferred martial art, Mixed Martial Arts (MMA) was the second priority, next was Taekwondo, then Karate, and finally Boxing. In addition, the martial artists’ preferred distance was less than 8 km, and a monthly training cost of 150,000 to 450,000 IDR (10 to 20 USD). Martial artists liked attending open classes, treated martial arts as a hobby, and favored attending classes once or twice weekly. With the lack of conjoint-related studies in the martial arts industry, the findings contributed to academicians and addressed issues of inadequate studies. Most importantly, the researchers presented managerial implications to leverage marketing techniques and develop the business operations of martial arts schools.
Complete plastid genome of Iris orchioides and comparative analysis with 19 Iris plastomes
Authors: Choi Tae-Young , Lee Soo-Rang
Published: April 2024

Iris is a cosmopolitan genus comprising approximately 280 species distributed throughout the Northern Hemisphere. Although Iris is the most diverse group in the Iridaceae, the number of taxa is debatable owing to various taxonomic issues. Plastid genomes have been widely used for phylogenetic research in plants; however, only limited number of plastid DNA markers are available for phylogenetic study of the Iris. To understand the genomic features of plastids within the genus, including its structural and genetic variation, we newly sequenced and analyzed the complete plastid genome of I. orchioides and compared it with those of 19 other Iris taxa. Potential plastid markers for phylogenetic research were identified by computing the sequence divergence and phylogenetic informativeness. We then tested the utility of the markers with the phylogenies inferred from the markers and whole-plastome data. The average size of the plastid genome was 152,926 bp, and the overall genomic content and organization were nearly identical among the 20 Iris taxa, except for minor variations in the inverted repeats. We identified 10 highly informative regions (matK, ndhF, rpoC2, ycf1, ycf2, rps15-ycf, rpoB-trnC, petA-psbJ, ndhG-ndhI and psbK-trnQ) and inferred a phylogeny from each region individually, as well as from their concatenated data. Remarkably, the phylogeny reconstructed from the concatenated data comprising three selected regions (rpoC2, ycf1 and ycf2) exhibited the highest congruence with the phylogeny derived from the entire plastome dataset. The result suggests that this subset of data could serve as a viable alternative to the complete plastome data, especially for molecular diagnoses among closely related Iris taxa, and at a lower cost.
Hypothermia effects on neuronal plasticity post spinal cord injury
Authors: Al-Nashash Hasan , Wong Ka-Leung , ALL Angelo H.
Published: April 2024

Background

SCI is a time-sensitive debilitating neurological condition without treatment options. Although the central nervous system is not programmed for effective endogenous repairs or regeneration, neuroplasticity partially compensates for the dysfunction consequences of SCI.

Objective and hypothesis

The purpose of our study is to investigate whether early induction of hypothermia impacts neuronal tissue compensatory mechanisms. Our hypothesis is that although neuroplasticity happens within the neuropathways, both above (forelimbs) and below (hindlimbs) the site of spinal cord injury (SCI), hypothermia further influences the upper limbs’ SSEP signals, even when the SCI is mid-thoracic.

Study design

A total of 30 male and female adult rats are randomly assigned to four groups (n = 7): sham group, control group undergoing only laminectomy, injury group with normothermia (37°C), and injury group with hypothermia (32°C +/-0.5°C).

Methods

The NYU-Impactor is used to induce mid-thoracic (T8) moderate (12.5 mm) midline contusive injury in rats. Somatosensory evoked potential (SSEP) is an objective and non-invasive procedure to assess the functionality of selective neuropathways. SSEP monitoring of baseline, and on days 4 and 7 post-SCI are performed.

Results

Statistical analysis shows that there are significant differences between the SSEP signal amplitudes recorded when stimulating either forelimb in the group of rats with normothermia compared to the rats treated with 2h of hypothermia on day 4 (left forelimb,p = 0.0417and right forelimb,p = 0.0012) and on day 7 (left forelimb,p = 0.0332and right forelimb,p = 0.0133) post-SCI.

Conclusion

Our results show that the forelimbs SSEP signals from the two groups of injuries with and without hypothermia have statistically significant differences on days 4 and 7. This indicates the neuroprotective effect of early hypothermia and its influences on stimulating further the neuroplasticity within the upper limbs neural network post-SCI. Timely detection of neuroplasticity and identifying the endogenous and exogenous factors have clinical applications in planning a more effective rehabilitation and functional electrical stimulation (FES) interventions in SCI patients.
Causal associations of particulate matter 2.5 and cardiovascular disease: A two-sample mendelian randomization study
Authors: Cao Ye , Feng Yi , Xia Nan , Zhang Jiancheng
Published: April 2024

Background

According to epidemiological studies, particulate matter 2.5 (PM2.5) is a significant contributor to cardiovascular disease (CVD). However, making causal inferences is difficult due to the methodological constraints of observational studies. In this study, we used two-sample Mendelian randomization (MR) to examine the causal relationship between PM 2.5 and the risk of CVD.

Methods

Genome-wide association study (GWAS) statistics for PM2.5 and CVD were collected from the FinnGen and UK Biobanks. Mendelian randomization analyses were applied to explore the causal effects of PM2.5 on CVD by selecting single-nucleotide polymorphisms(SNP) as instrumental variables.

Results

The results revealed that a causal effect was observed between PM2.5 and coronary artery disease(IVW: OR 2.06, 95% CI 1.35, 3.14), and hypertension(IVW: OR 1.07, 95% CI 1.03, 1.12). On the contrary, no causal effect was observed between PM2.5 and myocardial infarction(IVW: OR 0.73, 95% CI 0.44, 1.22), heart failure(IVW: OR 1.54, 95% CI 0.96, 2.47), atrial fibrillation(IVW: OR 1.03, 95% CI 0.71, 1.48), and ischemic stroke (IS)(IVW: OR 0.98, 95% CI 0.54, 1.77).

Conclusion

We discovered that there is a causal link between PM2.5 and coronary artery disease and hypertension in the European population, using MR methods. Our discovery may have the significance of public hygiene to improve the understanding of air quality and CVD risk.
County-level factors associated with a mismatch between opioid overdose mortality and availability of opioid treatment facilities
Authors: Rizk John G. , Saini Jannat , Kim Kyungha , Pathan Uzma , Qato Danya M.
Published: April 2024

Background

Opioid overdose deaths in the United States remain a major public health crisis. Little is known about counties with high rates of opioid overdose mortality but low availability of opioid use disorder (OUD) treatment facilities. We sought to identify characteristics of United States (US) counties with high rates of opioid overdose mortality and low rates of opioid treatment facilities.

Methods

Rates of overdose mortality from 3,130 US counties were compared with availability of opioid treatment facilities that prescribed or allowed medications for OUD (MOUD), from 2018-2019. The outcome variable, “risk-availability mismatch” county, was a binary indicator of a high rate (above national average) of opioid overdose mortality with a low (below national average) rate of opioid treatment facilities. Covariates of interest included county-level sociodemographics and rates of insurance, unemployment, educational attainment, poverty, urbanicity, opioid prescribing, depression, heart disease, Gini index, and Theil index. Multilevel logistic regression, accounting for the clustering of counties within states, was used to determine associations with being a “risk-availability mismatch” county.

Results

Of 3,130 counties, 1,203 (38.4%) had high rates of opioid overdose mortality. A total of 1,098 counties (35.1%) lacked a publicly-available opioid treatment facility in 2019. In the adjusted model, counties with an additional 1% of: white residents (odds ratio, OR, 1.02; 95% CI, 1.01-1.03), unemployment (OR, 1.11; 95% CI, 1.05-1.19), and residents without insurance (OR, 1.04; 95% CI, 1.01-1.08) had increased odds of being a mismatch county. Counties that were metropolitan (versus non-metropolitan) had an increased odds of being a mismatch county (OR, 1.85; 95% CI, 1.45-2.38).

Conclusion

Assessing mismatch between treatment availability and need provides useful information to characterize counties that require greater public health investment. Interventions to reduce overdose mortality are unlikely to be effective if they do not take into account diverse upstream factors, including sociodemographics, disease burden, and geographic context of communities.

Published: April 2024

Men having sex with men (MSM) represent a key population, in which sexually transmitted rectal infections (STIs) caused by Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and high-risk HPV (HR-HPV) are very common and linked to significant morbidity. Investigating the anorectal microbiome associated with rectal STIs holds potential for deeper insights into the pathogenesis of these infections and the development of innovative control strategies. In this study, we explored the interplay at the rectal site between C. trachomatis, N. gonorrhoeae, HR-HPV infection, and the anorectal microbiome in a cohort of 92 MSM (47 infected by CT and/or NG vs 45 controls). Moreover, we assessed the presence of Torquetenovirus (TTV), a non-pathogenic endogenous virus, considered as a possible predictor of immune system activation. We found a high prevalence of HR-HPV rectal infections (61%), especially in subjects with a concurrent CT/NG rectal infection (70.2%) and in people living with HIV (84%). In addition, we observed that TTV was more prevalent in subjects with CT/NG rectal infections than in non-infected ones (70.2% vs 46.7%, respectively). The anorectal microbiome of patients infected by CT and/or NG exhibited a reduction in Escherichia, while the presence of TTV was significantly associated with higher levels of Bacteroides. We observed a positive correlation of HR-HPV types with Escherichia and Corynebacterium, and a negative correlation with the Firmicutes phylum, and with Prevotella, Oscillospira, Sutterella. Our findings shed light on some of the dynamics occurring within the rectal environment involving chlamydial/gonococcal infections, HPV, TTV, and the anorectal microbiome. These data could open new perspectives for the control and prevention of STIs in MSM.
Cinema Novo vs. Beatlemania: Discovering the use of sound and music in two unfilmed and unpublished Brazilian screenplays from the mid-1960s
Authors: Mello Marcelo C.
Published: April 2024

In this article, I analyse sound and music in two unfilmed screenplays written by filmmakers Sergio Person and Jean-Claude Bernardet: SSS against Jovem Guarda (1966) and The Plague of the Ruminants (1967). Why would two leading figures of the politically engaged Cinema Novo jump into a commercial project with the ‘alienating’ leader of the Americanized Jovem Guarda? Their next project, The Plague of the Ruminants, contested the dictatorship. Inspired by magical realism, it would use Hollywoodesque fantastic spectacle. Through interesting interventions on the soundtrack, Person and Bernardet subtly denounced Jovem Guarda’s support for the military regime. This ironically contrasts with the soundtrack to SSS against Jovem Guarda. The article contributes to studies of sound and music in screenplays. I analyse different aspects pertaining to sound and music, compare these screenplays to other completed film projects by Person and Bernardet and place them in the context of Brazilian culture and politics.
Comportamento não saturado de solos estabilizados com cinzas volantes resultantes da queima de carvão
Authors: Araújo Nuno , Cristelo Nuno , Topa Gomes António , Miranda Tiago
Published: April 2024

A influência da sucção no comportamento de solos estabilizados quimicamente não foi ainda consistentemente quantificada, situação também motivada pelas dificuldades no procedimento experimental para caracterizar a resposta não saturada. Este artigo apresenta curvas de retenção obtidas para um solo estabilizado com cimento Portland ou com cimento alcalino. Apresentam-se também ensaios triaxiais, para as mesmas condições de cura, até aos 90 dias. Desconhecem-se tentativas anteriores de caracterizar curvas de retenção para solo-cimento alcalino; os resultados obtidos mostram que a estrutura de poros está formada aos 28 dias, antes do desenvolvimento da matriz de gel responsável pelo aumento da resistência. A curva de retenção alterou após estabilização, com formas diferentes para cada ligante – Portland gerou valor de entrada de ar mais elevado e uma faixa de sucção mais estreita. As diferenças entre curvas de cada ligante sugerem uma metodologia para avaliar a qualidade da estabilização por cimento alcalino.
La articulación de utopía comunista y pluralismo democrático en el Partido Comunista de España (1988-2018): El desgaste incontenible de una identidad
Authors: Almansa Pérez Rosa María
Published: April 2024

El artículo analiza el tratamiento que hace el Partido Comunista de España, a través de su documentación congresual y otra relevante, de la noción de democracia, y su relación con las de socialismo y comunismo, en las tres décadas que median entre las secretarías generales de Julio Anguita y José Luis Centella; esto es, entre el XII Congreso de 1988 y la segunda fase del XX en 2017. Con ello se descubre que, a pesar del abandono formal de la vía eurocomunista anterior, en el discurso oficial pervive una identificación casi total de socialismo o comunismo con democracia, concebida esta sobre todo en términos generales de participación y adquisición de derechos. A pesar de la radicalización discursiva en ciertos momentos, con Anguita como secretario general y con la vuelta al leninismo en 2017, ello tiene como consecuencia paradójica la relativización de su propio ideario marxista y comunista.
Upadacitinib-Induced Hepatitis B Reactivation Leading to Liver Transplant

Hepatitis B virus (HBV) reactivation can occur with the use of immunosuppressive therapy used to treat autoimmune conditions, such as rheumatoid arthritis. Janus kinase inhibitors, such as upadacitinib, have been approved for the treatment of rheumatoid arthritis. This is the first case report of a patient who used upadacitinib without antiviral prophylaxis against HBV and developed HBV reactivation, leading to fulminant hepatic failure necessitating emergent liver transplantation.
The Atemporal Silence of Aesthetics: Transfeminine Crossplay as Resources for Genderqueer Experimentation in Singapore
Authors: Ang Ming Wei , Ibasco Gabrielle
Published: April 2024

This study investigates how transfeminine crossplay—imagined or enacted crossdressing as feminine characters from anime and manga—offers aesthetic resources for genderqueer experimentation. We situate this investigation in Singapore, an Asian sociopolitical context which privileges social harmony and penalizes vocal dissent. Through interviews with six crossplay fans (some identifying as transgender but not others), we unpack how they harness aesthetics in crossplay to negotiate genderqueer trajectories. Crossplay aesthetics clarified gendered feelings and prospective gendered futures. It created gendered-aesthetic styles, forming new trajectories. But for some, it counterproductively constricted gender experimentation's inventiveness. We argue that aesthetic play constitutes a holding space to silently cultivate gender nonconformity, sidestepping Singapore society's demonization of dissent. By momentarily suspending ties to futural demands of gender identities, crossplay installs a sense of atemporality within gendered aesthetics, encouraging fans to engage gender as aesthetic considerations dissociated from personal and social histories of shame, suffering, and discrimination.
O Efeito da Incerteza da Política Econômica no Brasil nos Investimentos Corporativos
Authors: Batista Alexandre Teixeira Norberto , Souza Gustavo Henrique Dias , Bressan Valéria Gama Fully , Lamounier Wagner Moura
Published: April 2024

Objetivo: Este estudo investigou os efeitos da incerteza sobre a política econômica nos investimentos corporativos de empresas de capital aberto listadas no Brasil no período de 2010 a 2020. A incerteza sobre a política econômica pode intensificar o valor da opção de espera por novas informações e provocar atrasos nos investimentos corporativos das empresas, conforme sugere a Teoria das Opções Reais.
Método: Para analisar essa relação, utilizou-se o estimador do Método dos Momentos Generalizados Sistêmico, com dados em painel para uma amostra de 153 empresas, capaz de endereçar problemas de endogeneidade causados por dados dessa natureza.
Resultados: Verificou-se que aumentos na incerteza sobre a política econômica provocam reduções nos volumes de despesas de capital das empresas, com efeitos persistentes em pelo menos 4 trimestres futuros. Ademais, os investimentos corporativos se mostraram mais responsivos à incerteza econômica geral, medida pelo Indicador de Incerteza da Economia – Brasil (IIE-Br), do que à incerteza sobre a política econômica, medida pelo Economic Policy Uncertainty Index (EPU).
Contribuições: Confirmamos que a incerteza nas dimensões medidas pode atrasar os investimentos corporativos no Brasil. O modelo dinâmico proposto é adequado para previsão de respostas da firma à incerteza em períodos futuros. Este artigo contribui para um melhor entendimento da dinâmica das decisões de investimento corporativo no Brasil. Essas informações são úteis para analistas de mercado nas suas previsões, bem como órgãos governamentais na elaboração de políticas que garantam o equilíbrio dessas decisões.
Effects of the Differences Between FASB and IASB Accounting Policy for Leases
Authors: Santana Verônica de Fátima , Serafim Jandirson Dutra
Published: April 2024

Objective: This research investigates the effects of the 2019 US lease standards for US lessee companies, comparing with the potential effects of IFRS 16 to explore the economic reasons that would have led the FASB and the IASB to diverge from their joint lease standard project.
Method: We hand-collected detailed data on leases for 500 US lessees firms’ 2019 financial statements to first analyze Topic 842’s effects on financial ratios and to simulate these effects had the FASB adopted the same earnings recognition criteria in IFRS 16. Next, we investigate the value relevance of these observed and simulated effects on the stock market.
Results: Topic 842 generated significant variations in companies' financial indicators, but it was not possible to identify the value relevance of these variations due to model limitations. The IFRS 16 simulation shows a significant increase in EBIT and operating cash flows, but a drop in net income, which seems to have been incorporated into stock prices. This suggests the FASB’s decision to diverge from the IASB could include the desire to avoid lower earnings and their negative impacts on the stock market.
Contributions: This research adds to the literature first by focusing on the US when most of the recent studies investigated the IFRS world and, second, by exploring economic reasons rather than the hierarchy of power between the FASB and the IASB. Finally, we add a novelty derived from the detailed manual work which allowed us to estimate the effects had the US firms been under IASB’s jurisdiction.

What Differentiates Believers and Non-Believers of Conspiracy Theories? A Structural Analysis of Semantic Networks Regarding the Social Representations of Covid-19 Pandemic
Authors: Katerelos Ioannis , Koletsi Maria
Published: April 2024

Belief in conspiracy theories is close related with the adoption of behavioral patterns often associated with a direct dispute of scientific research, institutional and governmental practices. The recent Covid-19 pandemic revealed an ecosystem of stories and narratives promoting alternative explanations about a real public threat. The exposure to these narratives and their persuasion towards people’s cognitive structures is a crucial issue to be examined to identify the different strategies implemented, by individuals and groups, in order to address a direct threat to society. In the current exploratory research, we examined whether believing in conspiracy theories about Covid-19 pandemic, is possible to predict semantic networks as cognitive structures. The analysis of the research findings provided different patterns of thought about individual exposure to Covid-19 conspiracy theories, their persuasiveness, and the different levels of compliance to (state-promoted) health measures.

We discuss the importance of future research focusing on the level of acceptance of the role of different social institutions. A systematic analysis of conspiracy theories rationale is possible to address the cognitive bias organized on belief systems that offer a logical problem solving in social uncertainties. A more thorough study on the individual and group perception of the role of institutions, the level of their acceptance or dispute, as well as their direct and indirect impact on the development of socially responsible behaviors, within a shared social reality, could enhance our knowledge towards the development of effective social policies to confront the next public health crisis.
The Relationship Between Religion and Public Schools in the United States: An Introductory Brief
Authors: Grinberg Jaime
Published: April 2024

The United States of America (USA) has no official religion, and its constitution establishes a separation between state and religion. Hence, public schools should maintain such a separation in their relationship to religion.  However, historically, legally, and politically, this has been difficult, contentious, challenging, and complicated. Secularism has served as a balance to protect schools from religious intrusion and religion to keep the state from influence and control at bay. This paper briefly explains the seemingly watershed moment created by the US Supreme Court ruling enabling families in the state of Maine to obtain subsidies in the form of school vouchers to be applied toward tuition in religious private schools, thus breaking a legal tradition of denying public funds for their use for tuition covering of educational institutions sponsored by religious organizations. This paper introduces different dimensions for analyzing these relationships and explains a few legal and educational developments, legal rulings, and students’ rights.

Study on the evolution of permeability properties of limestone under different stress paths
Authors: Huang Gang , Lu Gang , Zhang Ji , Zhou Fengjun , Li Dongwei
Published: April 2024

Stress path change has a great relationship with the effect of deformation and strength of rock. However, the underground rock body is in the engineering environment where the stress field, seepage field, and other fields are coupled to change, the law of fluid flow in the rock body is complex and variable. The change in the stress field has an important effect on the seepage characteristics of rock body; therefore, it is necessary to study the pattern of rock permeability evolution pattern by different stress paths. This study is based on the study of limestone, conducting triaxial unloading seepage mechanics experiments, the evolution of permeability properties of limestone specimens was analyzed based on the test results. The results show that in the conventional triaxial loading seepage test, the permeability of the limestone decreases before the rock stress reaches the peak intensity and increases after that. Increasing axial pressure unloading surrounding pressure compression section, permeability loss rate and effective stress are in line with the changing law of Gaussian distribution function. Under the action of constant axial pressure unloading surrounding pressure, with the increase in unloading amount, the permeability rate of change appears to increase slowly, and in the late stage of unloading section, the permeability rate of change appears to surge. Unloading section permeability change rate and cumulative unloading amount are in line with the law of change of the exponential function. Creep unloading pressure seepage test found that unloading pressure stage strain-time and permeability-time evolution characteristics are in line with the exponential rule of change. The experimental results of this study can provide an important experimental and theoretical basis for the permeability analysis of low-permeability rock body under complex stress conditions in underground engineering.
The role of analytical performance specifications in international guidelines and standards dealing with metrological traceability in laboratory medicine
Authors: Greg Miller W.
Published: April 2024

The goal of metrological traceability is to have equivalent results for a measurand in clinical samples (CSs) irrespective of the in-vitro diagnostic medical device (IVD-MD) used for measurements. The International Standards Organization standard 17511 defines requirements for establishing metrological traceability of values assigned to calibrators, trueness control materials and human samples used with IVD-MDs. Each step in metrological traceability has an uncertainty associated with the value assigned to a material. The uncertainty at each step adds to the uncertainty from preceding steps such that the combined uncertainty gets larger at each step. The combined uncertainty for a CS result must fulfil an analytical performance specification (APS) for the maximum allowable uncertainty (umax
CS). The umax
CS can be partitioned among the steps in a metrological traceability calibration hierarachy to derive the APS for maximum allowable uncertainty at each step. Similarly, the criterion for maximum acceptable noncommutability bias can be derived from the umax
CS. One of the challenges in determining if umax
CS is fulfilled is determining the repeatability uncertainty (u
Rw) from operating an IVD-MD within a clinical laboratory. Most of the current recommendations for estimating u
Rw from internal quality control data do not use a sufficiently representative time interval to capture all relevant sources of variability in measurement results. Consequently, underestimation of u
Rw is common and may compromise assessment of how well current IVD-MDs and their supporting calibration hierarchies meet the needs of clinical care providers.

Published: April 2024

Invasive mammalian predators are arguably the most damaging group of alien animals for global biodiversity and their impacts are particularly damaging in endemic-rich insular ecosystems. Ferrets (Mustela furo) are well-known for their potential to establish self-sustaining feral populations. Yet, knowledge about their distribution and trophic interactions is scarce. Here, we provide ample evidence of a well-established and widespread population of ferrets on the subtropical island of Madeira (Portugal). Ferrets are using natural and human-dominated habitats, where they are preying on both native (e.g., Cory’s shearwaters (Calonectris borealis) and the endemic and IUCN Endangered Zino’s petrel (Pterodroma madeira)) and non-native vertebrates.

Representing slavery in visual art: a multimodal approach
Authors: Quadraro Michaela
Published: April 2024

This article explores some issues related to the trauma of slavery, colonialism and identity-formation processes through a multimodal analysis, which is particularly useful in studying the manifold meanings and relationships emerging from the forms of cultural and social representation such as visual art. A series of images, chosen within Ellen Gallagher’s art exhibition “AXME”, held at Tate Gallery in London, is investigated to deal with the discursive constructions of gendered and racial identities. Employing Kress and van Leeuwen’s model (2021 [1996]. Reading images: The grammar of visual design. London: Routledge), this article attempts to identify the signs related to categories such as gender and race, as well as the persistence of stereotypical representations in our contemporary societies.
From nasal respiration to brain dynamic
Authors: Shahsavar Payam , Ghazvineh Sepideh , Raoufy Mohammad Reza
Published: April 2024

While breathing is a vital, involuntary physiological function, the mode of respiration, particularly nasal breathing, exerts a profound influence on brain activity and cognitive processes. This review synthesizes existing research on the interactions between nasal respiration and the entrainment of oscillations across brain regions involved in cognition. The rhythmic activation of olfactory sensory neurons during nasal respiration is linked to oscillations in widespread brain regions, including the prefrontal cortex, entorhinal cortex, hippocampus, amygdala, and parietal cortex, as well as the piriform cortex. The phase-locking of neural oscillations to the respiratory cycle, through nasal breathing, enhances brain inter-regional communication and is associated with cognitive abilities like memory. Understanding the nasal breathing impact on brain networks offers opportunities to explore novel methods for targeting the olfactory pathway as a means to enhance emotional and cognitive functions.
Turning talk into text: the representation of contemporary urban vernaculars in Swedish fiction
Authors: Ganuza Natalia , Rydell Maria
Published: April 2024

This article examines the literary representation of contemporary urban vernaculars (CUV) in fiction. It focuses specifically on four Swedish novels published in the last ten years, whose narratives are set in the urban and increasingly multilingual, migrant-rich and class-stratified peripheral areas of Stockholm, the capital of Sweden. The analysis centers on how they are situated in these urban peripheries, using written representations of spoken, non-standard Swedish CUV as symbolic resources to give authenticity to the narratives. We examine the distinctive linguistic features that are employed to evoke the imagination of CUV, and how these are used to build the fictional characters and to create certain recognizable social personas and practices. We also discuss the linguistic features that are available but are not exploited to represent the fictional characters’ ways of speaking, and possible reasons why this is so. Finally, we examine how the novels exploit contrasts between registers, particularly between CUV and adult second-language speaker styles and between CUV and standard Swedish, and with what effects. The findings are discussed in the context of the broader social discourses about language, migration, CUV and adult second-language speakers in present-day Sweden.
A Hybrid Monte Carlo study of argon solidification

A GPU-based implementation of the Hybrid Monte Carlo (HMC) algorithm is presented to explore its utility in the chemistry of solidification at the example of liquid to solid argon. We validate our implementation by comparing structural characteristics of argon fluid-like phases from HMC and MD simulations. Examining solidification, both MD and HMC show similar trends. Despite observable differences, MD simulations and HMC agree within the errors during the phase transition. Introducing voids decreases the solidification temperature, aiding in the formation of a well-structured solids. Further, our findings highlight the importance of larger system sizes in simulating solidification processes. Simulations with a temperature dependent potential show ambiguous results for the solidification which may be attributed to the small system sizes. Future work aims to expand HMC capabilities for complex chemical phenomena in phase transitions.
Successfully Publishing With Undergraduate Coauthors in Psychology: Insights From Faculty With Top Track Records
Authors: Howell Jennifer L. , Giuliano Traci A. , Hebl William I.
Published: April 2024

Research in psychology and other fields has demonstrated the benefits of faculty-undergraduate collaborative research and shown that these research experiences can culminate in publication. To date, there has not yet been an in-depth investigation of the factors that enable faculty to successfully publish with undergraduate coauthors. In the present study, we used blended reflexive qualitative and quantitative methods to understand faculty perspectives on the topic by recruiting 38 faculty with extensive experience publishing with undergraduate coauthors from institutions in three categories: predominantly undergraduate, masters-granting, and doctoral-granting. These faculty responded to an open-ended survey regarding their experiences publishing with undergraduates. Although these faculty find great joy and meaning in publishing with undergraduates, they report facing obstacles such as a lack of student training, high rates of student turnover, and lack of time to dedicate to the process. Based on our results, we recommend that if institutions seek to increase their rates of faculty-student publication, they should dedicate resources, especially time, for student-faculty collaboration. In addition, departments should offer advanced training in scientific writing to facilitate student success in publication.
Studying the Great Patriotic War in the Shadow of the Current Crisis
Authors: Tromly Benjamin
Published: April 2024

The full-scale Russian invasion of Ukraine in 2022 has thrown the field of post-Soviet studies into upheaval, as scholars seek to strike a balance between expressing opposition to an aggressive war and maintaining scholarly neutrality and recognition of complexity. Against this backdrop, the study of Russia’s memory of the Great Patriotic War—which has been invoked to justify the invasion of Ukraine—is particularly challenging. In this light, the author reflects on research of one of the most controversial aspects of the Great Patriotic War, the history and memory of the collaborationist “Vlasov Movement,” in the current environment. This exercise reveals some important aspects of the current memory landscape in Russia and the conceptual problems faced by those who study it. In particular, scholars of the war as well as war memory face the difficulty of navigating an information space and scholarship in which history and memory are closely intertwined.
Pancasila as a Paradigm of Socio-Cultural Development
Authors: Putri Dina Lutfiana
Published: April 2024

Currently, there are many cultures that deviate from the prevailing norms. Lots of people forget the values of Pancasila that already exist. The existence of western culture makes our nation forget the culture that we have ourselves. Some of them are even more proud when using the culture of other nations. As a result, the culture that we have is eroded and gradually lost by the times. It's not a bad thing if we know other cultures, but we must not forget the culture of our own country. But today, they actually forget the identity of their own country, the prevailing paradigm is gradually disappearing. Paradigm is a person's perspective that can influence a person's way of thinking (cognitive), behaving (affective) and behaving (conative). Paradigm itself is very influential on a person's behavior in implementing Pancasila values. If the values in Pancasila are practiced properly, of course we will not lose our own national identity. The existence of Pancasila is also a guideline for upholding noble human values. Pancasila itself is essentially humanistic because Pancasila is based on the position of human nature or what is commonly called human rights. As stated in the five precepts, Pancasila always puts human rights first. This is in accordance with what is stated in the second precept, namely Just and Civilized Humanity. Thus, socio-cultural development must uphold human values and human dignity in order to produce cultured and civilized human beings.

The Dark Side of Indonesia’s Democracy: Does Pancasila still hold influence?
Authors: Abdurrahman Tama
Published: April 2024

Indonesia's transition to democracy has been celebrated globally, yet beneath the surface lies a complex interplay between democratic principles and the enduring influence of Pancasila, the state ideology. This paper delves into the less-explored facets of Indonesia's democracy, probing whether Pancasila still exerts significant influence in shaping the country's political landscape. The analysis begins by contextualizing Indonesia's democratic journey, tracing its evolution from the authoritarian era to the present. It then examines the foundational principles of Pancasila and their historical significance, emphasizing its role as a unifying force amidst Indonesia's diverse socio-cultural landscape. Drawing on recent political developments, the paper investigates instances where Pancasila's influence intersects with democratic ideals, as well as instances where tensions arise. It explores how Pancasila has been invoked both to promote national unity and to justify restrictions on dissent and minority rights. Furthermore, the paper assesses the implications of Pancasila's enduring influence on Indonesia's democratic governance, particularly in relation to issues of political pluralism, freedom of expression, and minority rights. It highlights the challenges of reconciling Pancasila's collectivist ethos with democratic principles of individual rights and freedoms. Through this analysis, the paper contributes to a deeper understanding of Indonesia's democracy by shedding light on its complexities and contradictions. It underscores the need for critical reflection on the role of Pancasila in shaping democratic norms and practices, urging for a nuanced approach that upholds democratic principles while honoring Indonesia's unique socio-cultural heritage.
