Behavioural avoidance of parasites in the environment generates what is known as the 'landscape of disgust' (analogous to the predator-induced 'landscape of fear'). Despite the potential for improving our inference of host–parasite dynamics, three limitations of the landscape of disgust restrict the insight that is gained from current research: (i) many host–parasite systems will not be appropriate for invoking the landscape of disgust framework; (ii) existing research has primarily focused on immediate choices made by hosts on small scales, limiting predictive power, generalizability, and the value of the insight obtained; and (iii) relevant ecological and evolutionary theory has yet to be integrated into the framework, challenging our ability to interpret the landscape of disgust within the context of most host–parasite systems. In this review, we explore the specific requirements for implementing a landscape of disgust framework in empirical systems. We also propose greater integration of habitat selection and evolutionary theories, aiming to generate novel insight, by exploring how the landscape of disgust varies within and across generations, presenting opportunities for future research. Despite interest in the impacts of parasitism on animal movement and behaviour, many unanswered questions remain. [ABSTRACT FROM AUTHOR]

Tool use has been observed in over two dozen families of birds, though few wild birds outside of corvids have been observed using tools in acts of agonism; we present additional accounts of this behavior in both corvids and cardinals. On 9 June 2023 we observed and video-recorded a male Northern Cardinal (Cardinalis cardinalis) repeatedly pick up a pebble and strike the side-view mirror of a vehicle in a parking lot at Great Smoky Mountains National Park, Tennessee, USA. We searched YouTube and found several videos of wild birds attacking their reflection in a mirror or window. None appeared to use a pebble or other weapon to attack, but a White-winged Chough (Corcorax melanorhamphos) used a pebble to strike the windshield of a vehicle and a Common Raven (Corvus corvax) dropped a stone on a domestic dog. We interpret our observation as indicating tool use by a Northern Cardinal, one of the few accounts outside of corvids of a bird using a tool in an act of agonism. We also show that online videos can help researchers detect novel behaviors, including tool use and tooling, in wild birds. [ABSTRACT FROM AUTHOR]

The detection of pharmaceuticals in aquatic ecosystems has generated concern for wildlife and human health over the past several decades. β‐adrenergic blocking agents are a class of drugs designed to treat cardiovascular diseases and high blood pressure. Metoprolol is a second‐generation β1‐adrenergic receptor inhibitor detected in effluent derived from sewage treatment plants. Our review presents an updated survey of the current state of knowledge regarding the sources, occurrence, and toxicity of metoprolol in aquatic ecosystems. We further aimed to summarize the current literature on the presence of metoprolol in various classes of aquatic species and to consider the trophic transfer of these contaminants in marine mammals. The biological impacts of metoprolol have been reported in 20 aquatic organisms, with a primary focus on cardiac function and oxidative stress. Our review reveals that concentrations of metoprolol that cause toxicity in aquatic species are above levels that are typical of marine and freshwater environments. Future studies should investigate the effects of metoprolol at lower concentrations in aquatic organisms. Other recommendations include (1) a further focus on noncardiac endpoints, because computational assessments of currently available molecular data identify gonadotropins, vitellogenin, collagen, and cytokines as potential targets of modulation, and (2) development of adverse outcome pathways for cardiac dysfunction in aquatic species to improve our understanding of molecular interactions and outcomes following exposure. As the next generation of β‐blockers is developed, continued diligence is needed for assessing environmental impacts in aquatic ecosystems to determine their potential accumulation and long‐term effects on wildlife and humans.

This study proposes a synergistic approach that aligns environmental sustainability with economic viability to meet the energy trilemma of energy security, affordability, and sustainability. Employing two qualitative methods-bibliometric analysis and systematic literature review- the research focused on Scopus-based articles related to renewable energy optimization using the VOSviewer software. The analysis revealed prevalent environmental tradeoffs in renewable energy schemes, including habitat loss, fragmentation, sediment transportation, and deforestation. Similarly, economic tradeoffs such as high initial costs, intermittency, reliability challenges, job security, resource scarcity, and supply chain risks were identified. Following a thorough examination, the study suggests solutions to manage these tradeoffs viz. strategic planning, continuous monitoring and adaptation, life cycle evaluation, policy and regulation implementation, and diversification of renewable energy sources. In conclusion, the study advocates a three-tiered recommendation for a smooth and predictable transition toward a secure energy future viz. integrated policy frameworks, and technological innovation.

Globally interpretable feature dimensions are one property, among others like prediction performance and compactness, that researchers can prioritize when inferring latent representations. Multidimensional representational spaces can capture complex structures such as hierarchical relationships, lexical entailment, and compositional features. Superficially different representations, such as graphs and multidimensional data, can capture the same structural relationships under appropriate settings. The dimensionality of a representation conveys relatively little information on its own. Cognitive scientists often infer multidimensional representations from data. Whether the data involve text, neuroimaging, neural networks, or human judgments, researchers frequently infer and analyze latent representational spaces (i.e., embeddings). However, the properties of a latent representation (e.g., prediction performance, interpretability, compactness) depend on the inference procedure, which can vary widely across endeavors. For example, dimensions are not always globally interpretable and the dimensionality of different embeddings may not be readily comparable. Moreover, the dichotomy between multidimensional spaces and purportedly richer representational formats, such as graph representations, is misleading. We review what the different notions of dimension in cognitive science imply for how these latent representations should be used and interpreted. [ABSTRACT FROM AUTHOR]

The most effective health communication builds from evidence-based best practices and theory. In practice, health campaigns rely on considerations often under-discussed in health communication, such as consistent agency-style client service, image management, and community coalition-building. Health outcome progress often requires change at multiple levels, from individual cognition and behavior to policy creation. These multi-level needs further highlight the importance of effective practical health communication supporting a range of outcomes and building toward replication. This article covers the complexities of building and implementing a theory-informed health communication structure for a multifaceted, place-based cancer prevention initiative. Part of the overall process includes detailing the internal communications of a health communication group, interorganizational communication, engaging community partner support, the message creation process, and longitudinal efforts on program maintenance and assessment. Furthermore, this article seeks to offer an example of the client service role a health communication team can play to combine theory, empirical message development, and community goals in whole community efforts. Ultimately, the goal is to share experiences from seven years of program work to help guide future community-based efforts in other health contexts and foster progress in theoretical and practical understandings of health communication.

Bayesian additive regression trees (BART) is an ensemble prediction method that is able to model complex, highly non-linear relationships in continuous and discrete data. Previous methods have utilized BART’s flexible, sum-of-trees model to perform variable selection that is non-parametric with respect to the functional form of the outcome. In this paper we introduce a method to detect interactions in a similar manner. Additionally, we present a BART-based pipeline for variable and interaction selection to build interpretable machine learning models that improve inference over existing methods named BARTselect. Simulation results demonstrate that our method is able to detect a high proportion of true interactions across a range of data settings. We conclude with two example data settings, examining interactions in medical expenditure data and newborn birth weight data. [ABSTRACT FROM AUTHOR]

Purpose: Concordance is an important dimension of the physician-patient relationship that may be linked to health care disparities. The purpose of this study was to determine if sex discordance between surgeon and patient impacts surgical outcomes. Methods: A retrospective review of prospectively collected data obtained from the Abdominal Core Health Quality Collaborative (ACHQC) registry was performed on all patients who underwent ventral hernia repair. Surgical site occurrences (SSO), surgical site infections (SSI), surgical site occurrence requiring procedural intervention (SSOPI) and 30-day readmission rates were recorded. Results: Female patients operated on by male surgeons have increased odds of having an SSI/SSO (OR 1.099, 95% CI 1.022–1.181), SSOPI (OR 1.156, 95% CI 1.031–1.297), and readmission (OR 1.259, 95% CI 1.128–1.406) when compared to male patients operated on by male surgeons. There was no significant difference in adverse outcomes between patient groups when operated on by female surgeons. Conclusion: Sex discordance between surgeon and patient is associated with increased odds adverse outcomes when male surgeons operate on female patients. [ABSTRACT FROM AUTHOR]

Passports are the number one form of individual identification when crossing borders resulting in counterfeit or modified passports being used to allow illegal travel. Here we report on the use of Diamond Dye to detect cells deposited by touch onto parts of the photograph page of a passport. The passport page was divided into a grid of 11 rectangles of approximately equal dimensions. Thumbprints were deposited at 10 of the 11 squares, with the 11th left blank as a negative control. The location and number of deposited cells were determined and recorded. Cellular material was removed from each square separately, using a moistened swab or a tapelift. Tapelifting was better suited for the substrate resulting in an increase in DNA recovered. The highest total quantity of DNA isolated from the 10 samples post extraction was 0.162 ng. Short tandem repeat data were obtained from all 10 samples using the GlobalFilerTM PCR Amplification Kit. The DNA profiles were single source or two-person mixtures and the donor was always the major contributor. These data show the potential to visualize cellular material deposited by touch and then generate STR data from an item such as a passport after only brief physical contact. [ABSTRACT FROM AUTHOR]

Quality II is a nascent paradigm (i.e., a distinct set of concepts) for reducing and containing errors and mitigating rework in construction. It has emerged from empirical observations of best practices implemented in two large-scale infrastructure assets delivered using alliancing—a relational delivery strategy—underpinned by: (1) a contractual joint venture agreement (CJV) that fosters a collaborative "no-blame" culture where all parties aim to deliver best-for-project outcomes; (2) sharing of risks and rewards; (3) delivering value for money; and (4) a program of continuous improvement. Questions, however, surround the generalizability of Quality II beyond the alliances from which best practices were identified. This paper introduces the concepts of Quality II and discusses the need to validate and operationalize its use more broadly within the practice of project procurement. The contributions of this paper are twofold: (1) a new way to contain (i.e., enhance the detection and minimize the adverse consequences) and reduce (i.e., limit the occurrence of) errors in construction is introduced—Quality II; and (2) it provides opportunities to initiate the cultural and organizational changes in practice needed to improve performance and productivity in construction.

Thermal Power Plant is a common power plant that generates power by fuel-burning to produce electricity. Being a significant component of the energy sector, the Thermal Power Plant faces several issues that lead to reduced productivity. Conventional researchers have tried using different mechanisms for improvising the production of Thermal Power Plants in varied dimensions. Due to the diverse dimensions considered by existing works, the present review endeavours to afford a comprehensive summary of these works. To achieve this, the study reviews articles in the range (2019–2023) that are allied with the utility of SC methodologies (encompassing AI-ML (Machine Learning) and DL (Deep Learning) in enhancing the productivity of Thermal Power Plants by various dimensions. The conventional AI-based approaches are comparatively evaluated for effective contribution in improvising Thermal Power Plant production. Following this, a critical assessment encompasses the year-wise distribution and varied dimensions focussed by traditional studies in this area. This would support future researchers in determining the dimensions that have attained limited and high focus based on which appropriate research works can be performed. Finally, future suggestions and research gaps are included to offer new stimulus for further investigation of AI in Thermal Power Plants. [ABSTRACT FROM AUTHOR]

ABSTRACT Gut microbiota regulate multiple aspects of host health, including metabolism and the development of the immune system. However, we still know relatively little about how the gut microbiota influences host responses to parasitism in wild organisms, particularly whether host‐microbiota interactions contribute to variation in parasitism across host species. The goal of this study was to determine the role of gut microbiota in shaping how birds respond to nest parasites and investigate whether this relationship varies between host species. Both eastern bluebirds (Sialia sialis) and tree swallows (Tachycineta bicolor) are parasitized by blow flies (Protocalliphora sialia), for which larval flies feed on nestlings' blood. We experimentally manipulated the gut microbiota of nestling bluebirds and tree swallows by dosing nestlings with an oral antibiotic or sterile water as a control. We then quantified nestling physiology (haemoglobin, glucose, parasite‐specific IgY antibody levels), body morphometrics, and survival until fledging, as well as blow fly abundance and size. An experimental disruption of nestling gut microbiota increased parasite abundance in tree swallows, but decreased parasite abundance in bluebirds, which suggests that the disruption has opposing effects on resistance across host species. Furthermore, experimental treatment delayed parasite development and had variable effects on nestling body morphometrics and physiology across the two host species. Together, these results suggest that gut microbiota contribute to host differences in resistance to blow flies and can influence host–parasite interactions. [ABSTRACT FROM AUTHOR]

Urbanization is a socioeconomic and geopolitical issue that affects the sustainability of resources. Therefore, this study uses Mean Item Score (MIS) and structural equation modelling (SEM) to analyse urbanization governance for the sustainability of WEF resources. The study established urbanization measures that significantly affect the WEF nexus and the urban governance approaches for WEF Nexus sustainability. The research findings revealed that urbanization has a statistically significant effect on the sustainability of the WEF nexus through indicators of urban place (population size and employment status), over-urbanization (overpopulation) and urban primacy. Moreover, the study revealed three urban governance approaches to ensuring the sustainability of the WEF nexus: Circular economy business models in the CBD, migration-orientated urban infrastructures and demand–pull governance modes for urban poverty. This study concludes with two policy recommendations for redesigning migration documents with WEF statistics and repurposing urban areas. [ABSTRACT FROM AUTHOR]

During the shooting motion of a basketball, the path of the ball from the beginning of the lift to release follows an S-shaped trajectory. This study is the first to investigate how two distinctive features of the S-shaped ball path, the maximum curvature, κmax, and terminal curvature, σ, are associated with longitudinal accuracy. The sagittal plane ball path and curvature were found using Bezier curves for 31 professional male basketball athletes. Terminal release curvature had a very strong positive correlation to intra-individual release velocity standard deviation (r = 0.73, p < 0.001) indicating that shooters with straighter terminal ball paths had better longitudinal shooting accuracy. It was also observed that κmax coincided with the transition to the forward shooting motion and that players with higher κmax tend to have a clear two-part shooting style rather than a single fluid motion. A comparison between groups of good and poor shooters identified a mean difference in κmax of 7.9 m−1 (p < 0.001, 95% CI: 11.8–4.0 m−1) suggesting that good shooters typically have a higher κmax than poor shooters.

• Chronic cannabis use patterns were associated with psychological dysfunction. • Chronic cannabis use patterns were linked with emotion-directed driving styles. • Dependent users were at greater risk of psychological dysfunction and risky driving. • Other substance use and the tendency to drive under the influence were controlled for. • Cannabis use indirectly influenced risky driving via effects on self-regulatory deficits. Research has suggested that problematic cannabis use is associated with self-regulatory impairments, psychopathology, and the tendency to engage in risk taking behaviours. However, no research has applied the combined dynamics of these factors to the topic of risky driving behaviour specifically. This study investigated whether specific cannabis use patterns (i.e., use onset, duration, frequency, and quantity) and likely dependence influenced driving styles, via their effects towards emotional dysregulation and psychopathology (i.e., anxiety, depression, anger), among an online sample of active Australian cannabis users (N = 200). Group comparisons showed that likely dependent cannabis users reported significantly greater difficulties regulating their emotions, greater incidence of psychopathological symptoms (i.e., anxiety, depression, and anger), and more frequent engagement in risky driving styles (i.e., anxious driving, aggressive driving, dissociative driving, and reckless driving), compared to non-dependent cannabis users. Examination of bivariate correlations demonstrated significant and positive associations between specific cannabis use patterns, emotional regulation difficulties, psychopathology, and risky driving styles. Structural equation modelling highlighted that cannabis use patterns indirectly predicted participants self-reported engagement in risky driving styles via their effects towards self-regulatory difficulties and psychopathology. The findings of this study have highlighted driving related risks associated with cannabis use, outside of typical acute-related impairments. In addition, the study has emphasised the importance of psychological dysfunctioning in the engagement of both substance use and risky driving styles. Understanding this in combination is important for future interventions targeting aberrant driving behaviours. [ABSTRACT FROM AUTHOR]

Introduction Osteoarthritis (OA), including that of the knee joint, represents a significant proportion of musculoskeletal injuries in the Canadian Armed Forces (CAF) due to the frequent, high-stress physical activity for which member participation is necessary. Platelet-rich plasma (PRP) is a conservative, autologous treatment that has the potential to relieve symptoms and improve functionality of military members to decrease the impact of the disease and ultimately strengthen the CAF. Materials and Methods A search of systematic reviews and meta-analyses was conducted to determine the efficacy of PRP injections in treating knee OA. The Scopus database, PubMed database, and Omni academic search tools were scoped for relevant publications. English literature, published up to and including March 2023, that investigated only clinically randomized controlled trials (RCTs) was eligible for inclusion. The results of network meta-analyses were investigated and summarized independent of reviews and non-network meta-analyses. Results A total of 225 unique systematic reviews and meta-analyses were initially identified, of which 39 publications, including 7 network meta-analyses, adhered to the defined inclusion and exclusion criteria. PRP was found to significantly alleviate symptoms of pain based on the visual analog scale and Western Ontario and McMaster Universities Arthritis Index pain scores within the 12-month follow-up. Function, activity, sport, quality of life, and stiffness were additionally determined to generally improve to a greater extent from PRP treatment compared to controls, while adverse effects were minor and temporary. PRP placed in the top 3 in 9 reported surface under the cumulative ranking curves, while individually reported rankings of leukocyte-poor and leukocyte-rich PRP both placed in the top 4. The clinical recommendations made were generally positive, with 17 publications acknowledging the benefits of PRP, 3 supporting possible efficacy, and an additional 8 recommending that it be an option for the conservative treatment of knee OA. Conclusion The results of this review support the efficacy of PRP for relieving symptoms of pain and improving function, stiffness, and quality of life for patients experiencing knee OA within 12 months. As a result, leukocyte-poor-PRP could be considered for members of the CAF with mild to moderate knee OA (Kellgren–Lawrence grades 1–3) to slow the progression of OA and extend the military careers of CAF members. There continues to be a need for future studies to investigate the longer-term effects of PRP to verify sustained benefits at follow-up points greater than 12 months, including findings of improvement in a delayed fashion at the 3- and 6-month timeframe compared to hyaluronic acid treatment.

Objective: To study the impact of tumour necrosis factor-α inhibitor (TNFi) therapy on the use of non-steroidal anti inflammatory drugs (NSAIDs) in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) in Iceland. Method: This registry cohort study used data from the nationwide database on biologics in Iceland (ICEBIO) and the Icelandic Prescription Medicines Register on disease activity, and filled prescriptions for NSAIDs, to study the period from 2 years before to 2 years after initiation of a first TNFi. Five randomly selected individuals from the general population matched on age, sex, and calendar time for each patient served as comparators. Results: Data from 940 patients and 4700 comparators were included. Patients with arthritis were prescribed 6.7 times more defined daily doses of NSAIDs than comparators (149 vs 22 per year). After TNFi initiation, NSAID use decreased to a mean of 85 DDD per year, or by 42% in RA, 43% in PsA, and 48% in axSpA. At TNFi initiation, the quintile of axSpA patients who used most NSAIDs reported significantly worse pain (mean ± sd 66 ± 21 vs 60 ± 23 mm), global health (70 ± 20 vs 64 ± 23 mm), and Health Assessment Questionnaire score (1.21 ± 0.66 vs 1.02 ± 0.66) than the other patients, whereas no significant differences were observed in the groups with peripheral arthritis. Conclusion: Patients with inflammatory arthritides requiring TNFi therapy use more NSAIDs than matched comparators, and consumption decreased following TNF initiation. Patient-reported measures are not associated with high NSAID use in patients with peripheral arthritis. [ABSTRACT FROM AUTHOR]

How can people talk about the past in a deeply fractured society, wounded by two centuries of colonial and postcolonial violence? In Oran—Algeria's second‐largest city—people find creative ways to speak without speaking about unspeakable pasts. They do this by creating poetic parallelism between urban forms—from skeletons of buildings to martyr images—in everyday speech and image‐events. In poetics, parallelism deploys similar linguistic forms to suggest equivalence of meaning for certain effects. In everyday life, parallelism is emergent social action that brings new publics to life through its performance. This parallelism enables ordinary people to talk to each other across entrenched sociopolitical divides, especially in contexts of authoritarian censorship. Through poetic parallelism, Oranis revivify the martyrs of independence as agentive witnesses to their decaying city's housing crisis. In doing so, they reconfigure the relationship between the colonial past and postcolonial present. [ABSTRACT FROM AUTHOR]

Purpose: To validate the New Zealand Anterior Cruciate Ligament (ACL) Registry's capture rate of revisions by cross‐referencing Registry data with reoperations data recorded by the Accident Compensation Corporation (ACC) and identify risk factors for all‐cause reoperation. Methods: Primary ACL reconstructions performed between April 2014 and September 2019 were individually matched on a record‐by‐record basis between the two databases. The ACC database was used to identify patients who underwent a reoperation with manual review of operation notes to identify whether a revision or other procedure was performed. This was combined with the number of revisions separately recorded in the New Zealand ACL Registry, which was used as the denominator value to calculate the Registry's capture rate of revisions. Patient and surgical data recorded in the Registry were analysed to identify independent predictors for all‐cause reoperation. Results: A total of 8046 primary ACL reconstructions were matched between the New Zealand ACL Registry and the ACC databases. The reoperation rate was 8.9% (n = 715) at a mean follow‐up of 2.5 years. Meniscal‐related procedures were the most common reoperation (n = 299, 3.7%), followed by revision ACL reconstruction (n = 219, 2.7%), arthrofibrosis (n = 185, 2.3%), cartilage (n = 56, 0.7%) and implants (n = 32, 0.4%). The New Zealand ACL Registry captured 96% of revisions. Younger age (hazard ratio [HR] > 1.4, p < 0.001), earlier surgery (HR > 1.3, p = 0.05), concurrent meniscal repair (medial meniscus HR = 1.9, p < 0.001 and lateral meniscus HR = 1.3, p = 0.022) and hamstring tendon autografts (HR = 1.4, p = 0.001) were associated with a higher risk of reoperation. Conclusion: The New Zealand ACL Registry captured 96% of revisions. Risk factors for all‐cause reoperation included younger age, earlier surgery, meniscal repair and hamstring tendon autografts. Level of Evidence: Level III. [ABSTRACT FROM AUTHOR]

Aim: Mountains are often used to study how environmental factors influence biodiversity. However, we have limited understanding of the processes causing biodiversity variation in mountains and whether such processes vary across trophic levels and spatial scales. The aim of this study was to evaluate (i) whether community assembly processes varied along elevational gradients, (ii) whether there were differences in such variation between primary producers (vascular plants) and secondary consumers (spiders) and (iii) whether there were scale dependencies in any elevational variation in community assembly. Location: Fennoscandia, Northern Sweden. Taxon: Vascular plants, spiders. Methods: We used phenotypic and phylogenetic dispersion to quantify how elevation influenced community assembly of vascular plants and spiders and whether there were any scale dependencies in such influences. Our original data of plant and spider communities came from our own field surveys, phenotypic dispersion was calculated based on matrices of ecological traits, and phylogenetic dispersion was calculated from phylogenetic trees for each organism group. Trait matrices were based on a combination of literature values and our own measurements. The phylogeny for vascular plants was based on a published plant super‐tree, whereas the phylogeny for spiders was created by ourselves based on the DNA sequences at the mitochondrial cytochrome c oxidase subunit 1 (COI). Results: Plants were environmentally filtered throughout all elevations and scales, but the importance of convergent evolution increased with elevation. For spiders, the importance of environmental filtering as well as niche conservatism increased with elevation. For both groups, communities at smaller scales were more influenced by biotic regulation and niche conservatism than at larger scales. Main Conclusions: Our study highlights both taxonomic differences and scale dependencies in how elevation influences community assembly. We argue that these results can have broad ramifications for our understanding of how spatial variation in biodiversity is generated and maintained. This may have particular relevance for our ability to predict the ecological consequences of climate change. Our results further highlight that high elevation specialists may suffer increased risks of climate driven extinctions due to a combination of increased competition and increased fragmentation of suitable habitats. Particularly for spiders, which had high elevation specialists clustered along specific lineages, such extinctions could lead to significant loss of phylogenetic variation. [ABSTRACT FROM AUTHOR]

Adolescent substance use is a growing public health concern, particularly given rising mortality rates from drug overdose deaths. The emergency department (ED) provides a unique opportunity to screen adolescents for substance use and provide brief interventions and linkage to care. This article provides a narrative review of the current evidence for ED screening and brief interventions for adolescents with substance use and identifies important opportunities, challenges, and areas for future research. There are several validated substance use screening and assessment tools for use with adolescents that can be implemented into ED screening programs. Brief motivational interviewing interventions may reduce alcohol use, but evidence for reductions of other substances is limited due to insufficient research. Both screening and interventions are feasible and acceptable in the ED setting with the appropriate resources. Increased training and the use of emerging technology can provide emergency physicians with opportunities to incorporate these tools into practice to when treating adolescents. Linkage to outpatient care for adolescents with substance use is understudied. The research on adult patient ED interventions and linkage to care is more robust and can provide insights for future ED studies among adolescents. ED-based adolescent substance use screening and interventions are necessary, feasible, and acceptable, but understudied. Future studies, focusing on optimizing ED interventions and linkage to care, are important next steps in determining the best care for adolescents with substance use who present to the ED.

Background: New diagnostic tools are needed to improve the diagnosis and risk stratification of cutaneous melanoma. Disease-specific microRNA signatures have been previously described via NanoString profiling of solid biopsy tissue and plasma. This study validated these signatures via next-generation sequencing technology and compared their performance against clinical metrics and other published melanoma signatures. Methods: RNA from 64 plasma and 60 FFPE biopsy samples from individuals with invasive melanoma or related benign/control phenotypes was extracted and enriched for microRNA. RNA sequencing was performed to compute MEL38/MEL12 signature scores. The results were evaluated with published NanoString and RNA sequencing datasets, comprising 548 solid tissue samples and 217 plasma samples, to predict disease status and patient outcome. Results: The MEL38 diagnostic signature classifies patients into discrete diagnostic groups via RNA sequencing in either solid tissue or plasma (P < 0.001). In solid tissue, the prognostic MEL12 signature stratifies patients into low-, intermediate- and high-risk groups, independent of clinical covariates. The hazard ratios for 10-year overall survival, based on observed survival intervals, were 2.2 (MEL12 high-risk vs low-risk, P < 0.001) and 1.8 (intermediate-risk vs low-risk, P < 0.001), outperforming other published prognostic models. MEL12 also exhibited prognostic significance in the plasma of 42 patients with invasive disease. Conclusions: The MEL38 and MEL12 signatures can be assessed in either solid tissue or plasma using RNA-seq and are strong predictors of disease state and patient outcome. Compared with other genomic methods, MEL12 was shown to be the strongest predictor of poor prognosis. MicroRNA expression profiling offers objective, accurate genomic information about a patient's likelihood of invasive melanoma and prognosis. [ABSTRACT FROM AUTHOR]

This study tries to ascertain the attitudes of tertiary learners’ internet meme consumption and its potential for pedagogical implications. Internet memes, as multifaceted cultural artefacts, have become pervasive in contemporary digital communication, influencing societal discourse and online interactions. Despite their prevalence, research on learners’ everyday experiences and attitudes towards memes in educational settings is a rarity. This research therefore aims to examine the affective and cognitive attitudes of undergraduate students towards internet meme culture. Utilising a cross-sectional survey design, data was collected from 119 second-year undergraduate students at St. Joseph's College (Autonomous), Tiruchirappalli, India. The questionnaire focused on measuring both affective and cognitive appeal towards meme consumption. The analysis revealed that memes as an educational tool have a positive impact on the affective and cognitive domains in a classroom setting. [ABSTRACT FROM AUTHOR]

Cannabis is a gateway drug that can lead to the engagement of other substances. Psychological dysfunctioning and dependence have been highlighted as primary components to substance misuse. The purpose of this study was to investigate what aspects of cannabis use and psychological dysfunctioning are associated with the engagement of other substances and impaired driving. Subject to screening, 200 active adult cannabis users completed an online survey. Existing data involving non-cannabis users (N = 833) were also implemented as comparative data. The comparisons suggested that cannabis users were far more likely to have used other drugs in the past 12 months, compared to non-cannabis users. Bivariate correlations and multiple regressions indicated that the degree of cannabis use and likely dependence, psycho-social motives for using cannabis, emotion dysregulation, and psychopathology were positively associated with the frequency of using and driving on other substances. Finally, an ANOVA demonstrated that outside of age, there were no apparent differences in substance use behaviours, motives for using cannabis, and psychological dysfunction, between medicinal and black-market cannabis users. These findings highlight the potential benefits of incorporating self-regulatory concepts into current road safety initiatives, which aim to reduce the interconnected issue of substance misuse and impaired driving behaviours.

OBJECTIVES: To assess the congruence between patient assignment and established patients as well as their association with Healthcare Effectiveness Data and Information Set (HEDIS) quality performance. STUDY DESIGN: A retrospective cross-sectional analysis from January 2020 to February 2022. METHODS: The study setting is a fully integrated health care delivery system in Phoenix, Arizona. The study population includes Medicaid patients who received primary care services or were assigned to a primary care physician (PCP) at the study setting by 5 Medicaid managed care organizations (MCOs). We identified 4 possible relationships between the established patients (2 primary care visits) and the assigned patients (assigned by the MCO to the study setting): true-positive, false-positive, true-negative, and false-negative classifications. Precision and recall measures were used to assess congruence (or incongruence). Outcome measures were HEDIS quality metrics. RESULTS: A total of 100,030 Medicaid enrollees (adults and children) were established and/or assigned to the study setting from 5 separate payers. Only 15% were congruently established and assigned to the physician (true-positive). The overall precision was 21%, and the overall recall was 37%. The HEDIS quality performance was significantly higher (P< .05) for established patients for 5 of 6 metrics compared with patients who were not established. CONCLUSIONS: The vast majority of assigned patients were not treated by the assigned PCP, yet better patient outcomes were seen with an established patient. As the health system rapidly adopts value-based payments, more rigorous methodologies are essential to identify physician-patient relationships. [ABSTRACT FROM AUTHOR]

This essay explores the prophetic vocation vis-a-vis the challenge of contemporary Christian nationalism by reading the book of Jonah in the Hebrew Bible in conversation with what Jesus says about the sign of Jonah in Matthew 12. This essay puts two readings of Jonah into dialog—one for womanist prophets and one addressed to White Christian nationalists. These texts reveal God's relentless mercy for the outsider and God's unwavering love for the prophet of the oppressed. The essay considers what the sign of Jonah means for race relations and the troubling rise of White Christian nationalism in the United States today. [ABSTRACT FROM AUTHOR]

Providing greater access to computer science (CS) education for K-12 students in the United States (U.S.) has increased interest in integrating CS concepts within authentic science, technology, engineering, and mathematics (STEM) contexts. Physical computing is one method that has demonstrated promising results in other countries (e.g. England) and has been receiving growing attention in the U.S., yet there remains limited research on physical computing within the U.S. Therefore, this study utilized a modified version of the Computing Attitude Questionnaire (Yadav, A., Mayfield, C., Zhou, N., Hambrusch, S., & Korb, J. T. (2014). Computational thinking in elementary and secondary teacher education. ACM Transactions on Computing Education, 14(1), 1–16) to examine changes in 71 middle school students' attitudes toward computing after participating in a four-week physical computing unit. Students reported significant gains in all five computing attitude constructs (definition, comfort, interest, classroom applications, and career/future use). Further analyses revealed male students had significantly greater gains than females in the career/future use construct, and there were no significant differences when controlling for completion of prior engineering design coursework (PEDC). Additionally, while the majority (77%) of students indicated they preferred physical computing over screen-based experiences for future computing lessons, analyses found gender and PEDC were not significant predictors of students' preference for learning computing concepts. This study provides implications for improving computer science instruction within authentic STEM contexts. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to assess the feasibility and acceptability of using EMA questionnaires and physiological data via wristbands to measure day-to-day occupational stress, musculoskeletal pain, and mental health among university employees (N = 23), across 10 work days. Adherence to the study protocol as well as participant experiences (via semi-structured interviews) with the protocol were used to assess feasibility and acceptability of the method. Results: Adherence to the study protocol was excellent. Participants wore the wristband for a mean of 9.7 days. Participants completed a mean of 24.5 EMAs (out of 30). Semi-structured interviews with participants revealed that a small number of participants had difficulties uploading data from the wristband. The timing of EMAs was challenging for some participants, resulting in missed EMAs, raising questions about whether EMA frequency and timing could be changed to improve adherence. Some EMA items were difficult to answer due to the nature of participants' roles and the work undertaken. Overall, the protocol was feasible and acceptable but highlighted future potential changes including using a different physiological data collection tool, reducing the number of EMAs, adjusting EMA timings, and reviewing EMA items.

• Situational Action Theory (SAT) was applied to phone use and driving. • Phone use was compared across highways, built-up areas and traffic lights. • Age, attitude, judgement, self-control were predictors across all environments. • Gender and risk of judgement varied across the different driving contexts. • Application of SAT has predictive utility in determining phone use while driving. Situational action theory (SAT) is a comprehensive theory that explains offending behaviour from the context of the interaction between interpersonal factors, such as morals, self-control, and habits, with situational factors, such as environmental risk and social conditions. Illegal hand-held mobile phone use while driving (MPUWD), a prevalent and risky road behaviour, has yet to be examined under the SAT framework. Therefore, by utilising SAT, this exploratory study sought to investigate the interpersonal and situational factors preceding hand-held MPUWD in three distinct road environments (highways, built-up areas and stopped-at-traffic lights). To achieve this, Queensland drivers aged over 18 who owned a mobile phone (N = 821, M age = 41.7 years, SD = 20.9 years) were invited to complete an online survey. Repeated measures ANOVAs demonstrated significant mean differences for participants' perceived risks associated with MPUWD and subsequent likelihood of offending across the three environments, with traffic lights being more conducive to MPUWD behaviours. Three hierarchical multiple linear regressions also revealed that age, attitude, risk of judgement, and self-control were significant predictors of MPUWD across all environments, while the results for gender, risk of injury and risk of being apprehended varied across the different driving contexts. Together, these factors explained 38.5–39.6 % of the variance in the perceived likelihood of illegally engaging in MPUWD. Overall, the findings indicated that the application of SAT has predictive utility in determining MPUWD engagement and can provide a more comprehensive framework for approaching and intervening in MPUWD behaviour.

The author presents a critical response to S. Pearl Brilmyer's essay "Queer Rigidity: Habit and the Limits of the Performativity Thesis" published in the Summer 2024 issue. Topics include the author's agreement with the conclusion reached by Brilmyer in her essay, his discussion of crystal habit as an alternative framework for understanding the persistence of people's attachments proposed by Brilmyer, and thoughts on Brilmyer's critique of queer studies and its characterization of voluntarism.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is globally increasing in prevalence. The rise of ASD can be partially attributed to diagnostic expansion and advocacy efforts; however, the interplay between genetic predisposition and modern environmental exposures is likely driving a true increase in incidence. A range of evidence indicates that prenatal exposures are critical. Infection during pregnancy, gestational diabetes, and maternal obesity are established risk factors for ASD. Emerging areas of research include the effects of maternal use of selective serotonin reuptake inhibitors, antibiotics, and exposure to toxicants during pregnancy on brain development and subsequent ASD. The underlying pathways of these risk factors remain uncertain, with varying levels of evidence implicating immune dysregulation, mitochondrial dysfunction, oxidative stress, gut microbiome alterations, and hormonal disruptions. This narrative review assesses the evidence of contributing prenatal environmental factors for ASD and associated mechanisms as potential targets for novel prevention strategies.

Structural habitats support high biodiversity by providing refuge, forage resources, and recruitment habitat that upwardly influence the broader faunal community structure. However, there are few system-wide studies that empirically measure communities before and after major shifts in habitat structure or availability, limiting our ability to predict the consequences of changes in structural habitat above local scales. We used the collapse of the Apalachicola Bay, Florida oyster population as a natural experiment to assess the impacts of estuary-wide structural habitat loss on the nekton community through long-term faunal monitoring data. Habitat losses of this magnitude are expected to decrease diversity and alter composition, so we expected to observe these changes in Apalachicola Bay after the oyster population collapse. We assessed changes in Gini-Simpson diversity and composition over a 21-year period encompassing the 2012 oyster collapse using generalized linear mixed models to account for confounding drivers. We surprisingly found no evidence that Gini-Simpson diversity or composition differed immediately before or following the collapse, which may be explained if estuarine fauna were able to effectively use other habitats. This suggests that proportional changes in diversity or composition from loss or gain of structural habitats cannot be assumed at the system-wide scale. [ABSTRACT FROM AUTHOR]

Uncertainty in ecosystem restoration can be mitigated by information on drivers of variability in restoration outcomes, especially through experimental study. In southeastern USA pine savannas, efforts to restore the perennial bunchgrass wiregrass (Aristida beyrichiana) often achieve variable outcomes in the first year. Although ecotypic differentiation and competition with other native vegetation are known to influence wiregrass seedling establishment and growth, to our knowledge, no studies have examined interactions between these drivers. We experimentally quantified individual and interactive effects of competition, seed source, and soil type on wiregrass density, size, and flowering culm production in the field. We sowed seeds from dry and wet sites reciprocally into dry and wet soils and weeded half of the plots. We found that competition removal resulted in significantly larger plants and a greater proportion of flowering plants with more culms on average, regardless of seed source or soil type. Seeds sourced from a wet site resulted in more plants per plot than seeds from a dry site, which might have been influenced by the greater number of filled seeds from the wet site. After seedlings become established, competition contributes to variation in growth and reproduction. Although competition removal could help start wiregrass populations, the necessity of mitigation depends on fire management needs. [ABSTRACT FROM AUTHOR]

Living polymers such as wormlike micelles have attracted considerable experimental and theoretical interest over the past three decades, but the differential-integral equations that describe the joint processes of reversible scission and stress relaxation were only recently developed and have not yet been solved. Here, we introduce a numerical method that is simple, stable, accurate, flexible, and fast compared to alternatives. After validating the method and its predictions, we provide a preliminary discussion on previously unquantified sources of uncertainty in a popular stochastic approach to modeling the same problem.

Background: Student teachers can find it difficult to inform their classroom practice with knowledge gained from education theory and research. Working with Design and Technology teacher education students, the authors have developed a model to support integration of knowledge-based thinking in lesson design for classroom practice. Purpose: This study explores the use of the Adaptive Subject Pedagogy Model to scaffold knowledge integration across the elements of an undergraduate technology education programme. Sample: Twenty-four Design and Technology students from three year-groups took part in the study. Design and methods: The study used focus groups to explore student perceptions of using the model, and analysis of student assignments to explore evidence of knowledge integration. Focus group transcripts were analysed inductively using thematic network analysis. Assignments were analysed using a deductive coding framework. Results: Students who understood the model as supporting planning for teaching in a broad sense were more likely to find the model helpful than those who saw the model as a lesson planning tool. Students valued the research element of the model for informing practice. Assignments gave mixed evidence of knowledge integration: some assignments showed convincing evidence of this, while others evidenced more partial integration. Conclusion: The study indicates that the model can support evidential integration, but that this is a challenging area for student teachers. This may be due to the different forms of knowledge students encounter across the academic and practicum elements of the programme, and/or to programme design if the practicum is not integrated effectively with other programme elements.

Philosophy for Children is a pedagogical approach practised worldwide. Although well known for its contribution to democratic teaching and learning its contribution to critical research is relatively unknown. In this paper we present the use of a Community of Enquiry (CoE), as conceptualised in Philosophy for Children, as a qualitative research method that foregrounds participant voice. Framed through Freirean critical pedagogy and social transformation, we present research undertaken with primary pre-service teachers in England, exploring their emerging teacher identity, and detail the method of how a CoE was enabled. We conclude and advocate that a CoE aligns with a research axiology concomitant with ethical critical practices and argue for an environment that enables the researcher, and participants, to generate data collaboratively and collectively through democratic dialogue. Finally, our findings show that a CoE can have much to offer qualitative critical scholars beyond its originally intended pedagogical contribution. [ABSTRACT FROM AUTHOR]

Introduction Methods Results Conclusion Despite evidence that participation in suicide research is not associated with worsening ideation, behaviors, or intent, the rise of intensive longitudinal methods to assess ideation and behaviors necessitates further investigation for potential iatrogenic effects. The present study assessed rates of change in suicide ideation (SI) in a 10‐day daily diary study.Seventy‐two adult participants with ongoing SI participated in 10 daily diary surveys and three follow‐up assessments. One open‐ended item was included to address participant experiences in the study.A multilevel piecewise growth model revealed steady declines in SI for participants over the 10 days. However, rates of SI increased during the follow‐up assessments, indicating that participation in the daily surveys was associated with general reductions in SI. Further, qualitative analyses of experiences in the study revealed the following themes: Useful (n = 34), Heightened Awareness (n = 21), Functional (n = 6), Not Useful (n = 6), and Beneficence (n = 4).This study demonstrated that participation in suicide research, including intensive longitudinal methods such as daily diary studies, did not have iatrogenic effects on participants with SI. Qualitative results demonstrated the numerous benefits participants derived while taking part in this study. [ABSTRACT FROM AUTHOR]

Although the original purpose of this article was to provide a comprehensive review of services provided for autistic children among Indigenous communities in Texas, USA, the authors' encounter with a significant paucity in availability of data and relevant reports on Indigenous services for ASD spurred the choice of a perspective article instead as it allows a more critical view into the pitfalls surrounding the state of autism services. The meager documentation availability presents a dilemma for both researchers and Indigenous communities since it often leads to misrepresentations of data, and limits understanding of existing support systems. This perspective article addresses these issues and serves to highlight the complexity of collecting data among Indigenous populations across the United States. Specifically, it emphasizes the challenges faced in Texas, shedding light on the various barriers such as variations in cultural identity, government trust, cultural awareness, and disability identity that impede data-collection efforts in providing effective services to Indigenous populations. We advocate for a radical transformation in understanding how to approach and report the prevalence of possible ASD autism among Indigenous children to provide effective and tailored services. Ultimately, this transformation aims to secure the necessary data to provide services that effectively complement the existing support systems within individual Indigenous communities to enable their fullest and most equitable participation in society. The discussion calls for a comprehensive roadmap to achieve the goal of increasing Indigenous data collection and availability while the conclusion outlines a suggested roadmap to achieve the goals of increasing data generation and available services to Indigenous communities, and ultimately, improving services for Indigenous children with ASD in Texas and their families.

Multi-level, place-based interventions have proven effective at promoting a range of health behaviors, including tobacco control and discouraging the uptake of tobacco products. This paper describes the implementation and impact of a 3-year, multi-level tobacco prevention and control program at a community-college minority-serving institution (MSI) on the Texas Gulf Coast within the context of a broader multi-sector, cross-functional health coalition. The intervention studied included a tobacco-free policy, a large-scale communication campaign highlighting parts of the intervention and prevention and cessation resources. The intervention was bolstered by the support of a community-led Steering Committee and tobacco control experts. Results from the first 3 years of implementation show that tobacco-free policies were largely supported by community members, awareness of the policy increased over time, and tobacco prevention and cessation resources were successfully embedded into campus norms. This multi-component approach shows how a community college was able to effectively reach students and staff on their campus to increase awareness of both the campus tobacco-free policy and the availability of tobacco prevention and cessation resources. Additionally, it also offers lessons for future tobacco prevention and control work in higher education. [ABSTRACT FROM AUTHOR]

According to one historic view of liberal education, such education is incompatible with the express pursuit of civic goods. Call that view 'pure liberal education'. Students engaged in pure liberal education are set free, temporarily, from utilitarian concerns, for a course of study aimed at intrinsic goods—most notably knowledge but also the formation of a virtuous mind. Proponents claim that a direct pursuit of civic goods would compromise the mode , matter , and/or integrity of pure liberal education—that is, its freedom from utilitarian concern, its wide-ranging and intrinsically valuable subject matter, and its commitment to following the truth wherever it leads. In reply, I offer a pedagogy that requires (almost) no departure from the pure liberal ideal yet which reserves a modest, though important, place for civic formation. That place emerges from the fact that academic and civic life 'overlap' in an important respect: both involve a conversation and thus a common set of virtues. The latter consist in those practices and dispositions that enable the conversation to go well, by encouraging mutual understanding and the formation of true beliefs. The existence of this overlap provides a way for pure liberal educators, who already expressly influence their students' academic formation, to likewise influence their civic formation. It consists in teachers consciously developing those virtues in their students, along with an awareness of the virtues' relevance for civic life. This pedagogy retains the matter and integrity of pure liberal education, with only brief introductions of the practical mode. [ABSTRACT FROM AUTHOR]

The study of facial expressions in mammals provided great advances in the identification of their emotions and then in the comprehension of their sentience. So far, this area of research has excluded birds. With a naturalist approach, we analysed facial blushing and feather displays in domestic fowl. Hens were filmed in situations contrasting in emotional valence and arousal level: situations known to indicate calm states (positive valence / low arousal), have rewarding effects (positive valence / high arousal) or induce fear-related behaviour (negative valence / high arousal). Head feather position as well as skin redness of comb, wattles, ear lobes and cheeks varied across these situations. Skin of all four areas was less red in situations with low arousal compared to situations with higher arousal. Furthermore, skin redness of the cheeks and ear lobes also varied depending on the valence of the situation: redness was higher in situations with negative valence compared to situations with positive valence. Feather position also varied with the situations. Feather fluffing was mostly observed in positively valenced situations, except when hens were eating. We conclude that hens have facial displays that reveal their emotions and that blushing is not exclusive to humans. This opens a promising way to explore the emotional lives of birds, which is a critical step when trying to improve poultry welfare. [ABSTRACT FROM AUTHOR]

Macronutrients play a vital role in host immunity and can influence host–pathogen dynamics, potentially through dietary effects on gut microbiota. To increase our understanding of how dietary macronutrients affect physiology and gut microbiota and investigate whether feeding behaviour is influenced by an immune threat, we conducted two experiments. First, we determined whether zebra finches (Taeniopygia guttata) exhibit shifts in physiology and gut microbiota when fed diets differing in macronutrient ratios. We found the type and amount of diet consumed affected gut microbiota alpha diversity, where microbial richness and Shannon diversity increased with caloric intake in birds fed a high‐fat diet and decreased with caloric intake in birds fed a high protein diet. Diet macronutrient content did not affect physiological metrics, but lower caloric intake was associated with higher complement activity. In our second experiment, we simulated an infection in birds using the bacterial endotoxin lipopolysaccharide (LPS) and quantified feeding behaviour in immune challenged and control individuals, as well as birds housed near either a control pair (no immune threat), or birds housed near a pair given an immune challenge with LPS (social cue of heightened infection risk). We also examined whether social cues of infection alter physiological responses relevant to responding to an immune threat, an effect that could be mediated through shifts in feeding behaviour. LPS induced a reduction in caloric intake driven by a decrease in protein, but not fat consumption. No evidence was found for socially induced shifts in feeding behaviour, physiology or gut microbiota. Our findings carry implications for host health, as sickness‐induced anorexia and diet‐induced shifts in the microbiome could shape host–pathogen interactions. [ABSTRACT FROM AUTHOR]

Melanoma clinical outcomes emerge from incompletely understood genetic mechanisms operating within the tumor and its microenvironment. Here, we used single-cell RNA-based spatial molecular imaging (RNA-SMI) in patient-derived archival tumors to reveal clinically relevant markers of malignancy progression and prognosis. We examined spatial gene expression of 203,472 cells inside benign and malignant melanocytic neoplasms, including melanocytic nevi and primary invasive and metastatic melanomas. Algorithmic cell clustering paired with intratumoral comparative two-dimensional analyses visualized synergistic, spatial gene signatures linking cellular proliferation, metabolism, and malignancy, validated by protein expression. Metastatic niches included up-regulation of CDK2 and FABP5, which independently predicted poor clinical outcome in 473 patients with melanoma via Cox regression analysis. More generally, our work demonstrates a framework for applying single-cell RNA-SMI technology toward identifying gene regulatory landscapes pertinent to cancer progression and patient survival.

Birds maintain some of the highest body temperatures among endothermic animals. Often deemed a selective advantage for heat tolerance, high body temperatures also limits birds' thermal safety margin before reaching lethal levels. Recent modelling suggests that sustained effort in Arctic birds might be restricted at mild air temperatures, which may require reductions in activity to avoid overheating, with expected negative impacts on reproductive performance. We measured within-individual changes in body temperature in calm birds and then in response to an experimental increase in activity in an outdoor captive population of Arctic, cold-specialised snow buntings (Plectrophenax nivalis), exposed to naturally varying air temperatures (− 15 to 36 °C). Calm buntings exhibited a modal body temperature range from 39.9 to 42.6 °C. However, we detected a significant increase in body temperature within minutes of shifting calm birds to active flight, with strong evidence for a positive effect of air temperature on body temperature (slope = 0.04 °C/ °C). Importantly, by an ambient temperature of 9 °C, flying buntings were already generating body temperatures ≥ 45 °C, approaching the upper thermal limits of organismal performance (45–47 °C). With known limited evaporative heat dissipation capacities in these birds, our results support the recent prediction that free-living buntings operating at maximal sustainable rates will increasingly need to rely on behavioural thermoregulatory strategies to regulate body temperature, to the detriment of nestling growth and survival.

Endophytic bacterium from the flower of Nyctanthes arbor-tristiswas isolated and identified as Cronobactersakazakii. The supernatant of the biomass of this endophyte was utilized for AgNps synthesis which was confirmed by a change in color and characterized by using UV-Visible spectrophotometer, FTIR, FESEM, EDAX, Zeta potential and DLS. The antibacterial efficacy of the CS-AgNPs against Gram positive and Gram negative bacteria was determined via agar well diffusion, MIC, MBC and biofilm formation assays. The antioxidant and anti-arthritic assays were also performed. The result revealed the synthesis of the semi-spherical CS-AgNPs and showed antibacterial activity. This report is the first to reveal the isolation and identification of endophytic bacterium from the flower of Nyctanthes arbor-tristis, along its nanomaterial synthesis, characterization and biomedical applications. Our result implies that the synthesized AgNPs can be utilized as an effective antimicrobial, antioxidant and anti-arthritic agent and can be incorporated in pharmaceutical formulation for drug development.

Little information on fecundity has been published for Channa argus (Northern Snakehead), the most invasive and widespread species of Channidae in North America, neither in its native nor introduced range. I examined specimens collected from fish lifts at the Conowingo Dam in the lower Susquehanna River. Gonad mass averaged 67 g (18 g–154 g) for females with an average total length of 614.7mm (490 mm–72 mm) and mass of 2533 g (1237 g–4155 g). Female gonadosomatic index averaged 0.028 or 2.8% (standard deviation = 0.01; min–max = 0.9–8.5%). Average fecundity (63,569 eggs/female; min–max = 21,790 –213,180 eggs/female) was similar to that reported for other native and introduced populations and increased with female mass. Two peaks in egg diameter were apparent with diameters varying between 210 and 700 µm (average = 1032 µm, SE = 26.7; n = 1223). Ancillary collections in July yielded ovaries with 19% fewer eggs than expected by female mass, but greater egg sizes (average = 1411 µm). Results indicate that females could partially spawn during spring, retain inchoate eggs that mature for later spawns, and spawn again in summer or fall. [ABSTRACT FROM AUTHOR]

Sometimes skeptics are tempted to dismiss world beliefs as meaningful phenomena. Such dismissal, we argue, is a mistake. How beliefs about many broad topics impact behavior is well-established. Psychologically rich world beliefs have also peppered the cultural milieu for centuries. Multiple, decades-old literatures have already established psychometrically the existence of world beliefs, proposed effects, and developed sufficient theory to define the beliefs and explain effects (e.g., Belief in a Just World literature). However, a shared, operationalized list of belief dimensions was lacking. Does one craft such a list a priori, with a specific outcome in mind – the typical approach – or seek to discover pre-existing dimensionality empirically, with no outcome privileged – similar to how Big Five traits were identified? The former being tried (Janoff-Bulman, 1989), Clifton and colleagues (2019) chose the latter, sparking an emerging, interdisciplinary effort. Yet the origins of these beliefs remain unknown and developmental psychologists are, now, sorely needed. [ABSTRACT FROM AUTHOR]

Community concerns surrounding syringe waste are a common barrier to syringe services program (SSP) implementation. In Kanawha County, West Virginia, community opposition to SSPs resulted in the closure of needs-based SSPs prior to and during an HIV outbreak among persons who inject drugs (PWID). This qualitative analysis examines views of PWID and community partners on syringe waste and disposal associated with needs-based SSPs. Qualitative interviews with 26 PWID and 45 community partners (medical and social service providers, law enforcement personnel, policymakers, and religious leaders) were conducted. Interviews were recorded, transcribed, and coded. Code summaries described participants' views on syringe waste and disposal and needs-based SSPs. Community partners and PWID who favored needs-based SSPs reported that needs-based SSPs had not affected or reduced syringe waste. Conversely, community partners who favored one-to-one exchange models and/or barcoded syringes described needs-based SSPs increasing syringe waste. Community partners often cited pervasive community beliefs that SSPs increased syringe waste, risk of needlesticks, drug use, and crime. Community partners were unsure how to address syringe waste concerns and emphasized that contradictory views on syringe waste posed barriers to discussing and implementing SSPs. Participants' views on whether syringe waste was associated with needs-based SSPs often aligned with their support or opposition for needs-based SSPs. These differing views resulted in challenges finding common ground to discuss SSP operations amid an HIV outbreak among PWID. SSPs might consider addressing syringe waste concerns by expanding syringe disposal efforts and implementing community engagement and stigma reduction activities. [ABSTRACT FROM AUTHOR]
