The case study explored the effects of illegal mining activities on Ghana’s sustainable development goals. Using case studies of two districts, the political settlement theory was used to investigate how the politics of power relations can lead to environmental change. Through interviews and focal group discussions, the study revealed an inextricable linkage between actors at the local, national, and international levels and environmental destruction. The study found that most of the sustainable development goals such as, right to safe and clean drinking water, human health, healthy environment, destruction of farmlands, food insecurity, education, eradicating hunger and poverty, amongst others have been significantly affected by the activities of illegal mining. The study thus recommended immediate policy interventions to remedy the situation before it reaches a tipping point.</p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

By analyzing the Sustainable Development Index (SDI) alongside CO₂ emissions per capita, the study identifies a clear tension between economic activity and environmental health. While Nigeria has experienced a steady rise in its SDI, reflecting improved policy integration, CO₂ emissions remain high due to continued dependence on fossil fuels. A correlation coefficient of r = −0.41 indicates that environmental degradation significantly undermines sustainability efforts. The research also highlights governance weaknesses and poor policy enforcement as primary challenges. To address these issues, the study recommends strengthening environmental oversight and incentivizing the transition to renewable energy sources to achieve long-term, carbon-neutral growth.</p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Consequently, global demand for lithium is booming, expected to triple by 2030. The Lithium Triangle, composed of Argentina, Bolivia, and Chile, is assuming an essential role in satisfying this demand since it is home to half of the world’s lithium reserves. However, of the three countries, only Chile has successfully transformed most of its reserves into commercially viable resources, making it the second highest lithium producer in the world. Bolivia, Argentina, and Chile have adopted starkly different approaches to governing their lithium industries. Part I will outline Bolivia’s statist approach, their constitution enshrining the state’s ownership of the mineral and its control over its entire productive chain. Part II will outline Argentina’s decentralized, investor-friendly approach under which the provinces own the mineral and liberally grant mining rights to investors who benefit from a myriad of special tax benefits. Part III will outline Chile’s centralized, mixed public-private approach in which the state retains ownership of the mineral while meticulously negotiating and closely supervising the conditions of mining rights extended to two private actors. Part IV will compare the three countries’ approaches and theorize that, in a region characterized by weakened state capacity, Chile’s governance style has empowered it to significantly outpace Bolivia and Argentina in lithium production. Lastly, Part V will address the vulnerabilities of generalizing about the success of the Chilean model, accounting for confounding variables such as the role of indigenous communities, Chile’s favorable geographic conditions, and Chile’s relatively stronger state capacity.</p>", "language": "eng", "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

The Palauan Constitution uniquely establishes traditional law as equally authoritative to statutes, leading the Supreme Court to struggle with how to identify and apply these fluid traditions. This complexity is intensified by a shifting jurisdictional standard that has swung from a “very liberal” approach to a restrictive “injury-in-fact” requirement and recently back to a nearly unlimited standard. This current era of expansive jurisdiction has forced the Court into the role of a frequent arbiter of internal clan disputes, particularly through declaratory judgments. Consequently, Palau stands at a crossroads, needing to determine whether to maintain this high level of judicial intervention or return to a more restrained approach.</p>", "language": "eng", "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

Hence, this article aims to fill that scholarship gap by answering the following question: how have regional bodies responded to COVID-19 concerning the right to health in Latin America? It is overall argued and found herein that: (1) there is a regional system on the right to health in pandemics such as COVID-19, about which a human rights-based approach provides a unifying standard; and (2) this system is embedded within the Organization of American States’ three-pillar framework, consisting of the Pan-American Health Organization, the Inter-American Commission on Human Rights, and the Inter-American Court of Human Rights. A human rights-based approach to health, which relies on international human rights law on the right to health, is considered a key component of the conceptual general framework herein. The Article analyzes the COVID-19 related practices of the three above-mentioned bodies. A central part of this Article’s methodology utilizes findings of convergences, synergies, and divergences between those bodies regarding the right to health during pandemics like COVID-19.</p>", "language": "eng", "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

This Article examines human rights violations and the supply chain disruptions resulting from drone warfare. Three case studies are analyzed: the Russia/Ukraine war, the Israel/Palestine war, and the Sudanese civil war. Modern warfare tactics can be seen in actions taken by the Houthis in West Yemen in response to the Israel/Palestine war, in which unmanned surface vessels, cruise missiles, unmanned underwater weapons, and drones are being used to stop, damage, and sink ships. Such conflicts result in supply chain disruptions. The Russia/Ukraine war has resulted in significant disruptions to the supply chains for energy, wheat, and oil. In addition, it is a basic tenet of international humanitarian law that innocent civilians should not be targeted, yet fully autonomous robots may not be able to distinguish military targets from civilians. There is an urgent need for intervention.

Since July 20, 1974, around 160,000 Greek-Cypriot refugees have fled to areas south of the United Nations-controlled buffer zone and around 40,000 Turkish-Cypriots have fled north. On August 2, 1975, at the third round of the Vienna talks, an agreement was reached between the two sides for the voluntary regrouping of populations. The agreement made it possible for the Turkish and Greek-Cypriots to live in two geographically separate areas and under their own administrations. Critically, it made no provision regarding existing property rights.</p>\n<p>The legal developments concerning the land of the Greek-Cypriot refugees in Turkish-controlled areas over the past 50 years have been subjected to intense political and legal scrutiny at the international level. This scrutiny includes some seminal judgements delivered by the European Court of Human Rights and the European Court of Justice. The same cannot be said for the southern properties the members of the Turkish community left in areas controlled by the Republic of Cyprus following the military operations in 1974. An international legal body is yet to conduct a comprehensive study and issue a ruling on the matter. This Article aims to provide insight into this complicated and politically sensitive issue.</p>\n<p>Part I of this Article provides a general overview of the legal framework governing the matter and proceeds with a more detailed examination on the scope of Law 139/1991. Part II considers the overall legal and procedural difficulties the Turkish-Cypriots face in pursuing judicial review proceedings against governmental authorities. Part III entails a more detailed checklist of the problematic areas under international law and examines the potential infringements of the human rights jurisprudence with a special focus on the principles on the right to free movement, respect for home and family life, rights to property and access to court, and discrimination based on residence or race. With the perspective that the identified violations cannot be justified based on an á-la-carte invocation of the “doctrine of necessity,” Part IV of this Article briefly discusses the ethical and legal considerations that should be noted in regard to the custodianship status of a non-Muslim individual over the properties of Muslim pious foundations established with the objective of promoting religious and charitable activities. In conclusion, this Article assesses the statutory amendments adopted in 2010 and comments on whether they have had any practical consequences in the name of improving the legal climate for members of the Turkish community.</p>", "language": "eng", "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

To compensate, misère researchers typically weaken the comparison relation by restricting to a subset of games, especially to a \"universe\" (closed under addition, conjugation, and options). For some well-studied universes (like the dicot and dead-ending universes), there exist finite comparison tests and also complete characterisations of their invertible elements; more recently, the invertible elements of every \"parental\" universe have been characterised. In this paper, we study the recently-defined universe of \"blocking games\" (containing both dicots and dead-ending games): we develop a finite comparison test, and we improve on the general invertibility characterisation by showing that, as in dead-ending, a game is invertible modulo blocking if and only if it is free of previous-win subpositions (or is equal to such a form).\n \nMathematics Subject Classifications: 91A46, 06F05, 20M14, 20K27\n \nKeywords: Combinatorial Game Theory, Ordered semigroups", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Previous experimental work using artificial language learning experiments has shown that learners prefer harmonic patterns. This suggests that the typological trend for harmony may, at least in part, be driven by a cognitive bias. However, it is well-documented that specific categories sometimes contradict this tendency. Here, we investigate one such case in the domain of the noun phrase. While many nominal dependents exhibit harmony, adjectives and genitives do not: adjectives tend to follow the noun and genitives tend to precede. Previous experiments have identified the existence of cognitive biases that keep these dependents split across the head noun in contexts where there is no conventional language system in place. In this study, we use a silent gesture experiment to examine whether the specific biases that apply to these two dependent types compete with a general preference for harmony in an artificial language learning task. Specifically, we examine whether participants’ learning behaviour is consistent with a preference not just for harmony, but for a non-harmonic order where adjectives follow and genitives precede the noun. What we find, instead, is that participants’ preference for consistent language systems is not modulated by category-specific biases for prenominal genitives and postnominal adjectives. We discuss the implications of this finding for explanations of typological tendencies which link them to cognitive biases.</p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Existing studies often emphasize human linguistic uniqueness without adequately accounting for semiotic continuities across species. To address this gap, the study conceptualizes communication as a semiotic continuum rather than a binary distinction. Using a qualitative comparative design, the research analyzes multimodal data from human communication and selected animal systems, including honeybee dances, dolphin echolocation, birdsong, and primate alarm calls. Data were examined through a coding framework based on Peircean semiotics and Hockett’s design features to ensure analytical rigor and comparability. The findings indicate that human communication is distinguished by symbolic abstraction, open-ended productivity, recursion, and metacommunication. However, animal communication systems also demonstrate structured, intentional, and adaptive properties shaped by ecological and social demands. Continuities across species include proto-syntactic patterning in primate calls, cultural transmission in birdsong, and multimodal coordination in dolphins and bees. Despite these shared features, animal systems generally lack the generativity and metalinguistic reflexivity characteristic of human language. The study concludes that communication should be understood as a graded semiotic continuum, with human language representing the most elaborated form of meaning-making rather than an isolated system. This reconceptualization contributes to theories of language evolution and broadens semiotic inquiry by situating human communication within a wider ecology of signs. </p>", "language": "enm", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

In this study we gave patients in the waiting room seven hypothetical emergency medical scenarios, two of which were training simulation scenarios, and we asked them how long they would be willing to delay their care if the different scenarios were actually occurring in the emergency department (ED). Our objective was to investigate whether patients in the ED waiting room would be willing to delay their care if they knew that there were simulation training scenarios occurring. </p>\n<p><strong>Methods:</strong> This was a prospective convenience sample of participants conducted at a Level 1 trauma centre. Participants completed a survey that presented seven hypothetical scenarios, including two in-situ simulation scenarios. They were then asked to indicate the amount of additional wait time they would deem acceptable for each scenario.</p>\n<p><strong>Results: </strong>Responses to the two in-situ simulation scenarios indicated that 342 (40%) and 335 (40.5%) of the 827 study participants, respectively, were willing to wait > 40 minutes for these to occur. In contrast, and after controlling for age, sex, waiting time, and time of recruitment, subjects reported they would tolerate shorter wait times for simulation scenarios than for real patient-care scenarios. [Willingness to wait > 40 minutes for the five real scenarios ranged from 70.5–79.9%, P < .05). </p>\n<p><strong>Conclusion:</strong> While patients demonstrated lower tolerance for simulation-related delays than for routine clinical care, our results showed that most were still willing to wait up to an additional hour to allow in-situ simulation to proceed. These findings indicate that in-situ simulation is broadly acceptable to patients and supports its continued use in clinical settings. </p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Such heat exposure also strains healthcare systems via increased utilization, a burden which can challenge systems’ capacities. Health impacts vary geographically with urban heat islands potentially contributing to higher temperatures and greater health risks. However, those most vulnerable to this exposure are not well identified. Our objective in this novel study was to compare and quantify differences in emergency medical services (EMS) use by selected patients during hot days in Rhode Island. Patients were recruited from low socioeconomic residential locations, stratified by whether they accessed EMS from within one of the state’s “urban heat islands,” or from other locations without “heat island” effects. We also compared selected patient demographic characteristics, and other EMS run data, between events associated with EMS access from these two types of areas.</p>\n<p><br><strong>Methods:</strong> This retrospective, cross-sectional cohort study evaluated how the probability of an EMS encounter varied in response to daily mean temperature and the urban heat island status of the encounter location. We aggregated EMS dispatch data, daily mean temperature, urban heat island classification and the Area Deprivation Index of the encounter location. A quasi-Poisson regression model assessed the relationship between EMS encounter frequency and potential risk factors including daily temperature, urban heat island status, year, day of the week, sex, age, and relevant interaction terms. The model was restricted to low socioeconomic, residential encounter locations to reduce confounding (noted elsewhere by year) and focus on the target population. The primary outcome was the rate ratio (RR) of EMS encounters for urban heat island locations vs locations without an urban heat island effect, in response to summer temperatures. Secondary outcomes included RRs of EMS encounters stratified by age, sex, weekday vs weekend, and year.</p>\n<p><br><strong>Results:</strong> Higher temperatures were associated with increased EMS call rates across all demographic subgroups. A 5 °F (2.8 °C) increase in mean daily temperature was associated with an increase in an overall EMS encounter rate of 1.5% (RR, 1.015; 95% CI, 1.005-1.031, P = .004). On a weekday in 2021, at 75 °F degrees, 68 EMS encounters would be predicted for the residential, low socioeconomic status locations in the state while at 95 °F, 73 EMS encounters would be expected. The EMS rates were consistently higher in urban heat islands across all study years, after accounting for daily temperature, year, day of the week, demographic characteristics, population size and interactions between age, sex, urban heat island and weekday vs weekend. The largest relative increase in EMS encounters was observed in 2019, with rates 34% higher in urban heat islands compared to locations without an urban heat island effect (RR, 1.34; 95% CI, 1.27-1.42). The smallest increase occurred in 2020 (RR, 1.12; 95% CI, 1.06-1.18).</p>\n<p><br><strong>Conclusion:</strong> In residential and low socioeconomic locations, living in an urban heat island increased the probability of an EMS encounter, highlighting potential compounding effects of social and environmental vulnerability. As climate change intensifies extreme heat events, locationally targeted interventions may be critical in reducing heat-related health impacts.</p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

While sex disparities in the evaluation and treatment of chest pain are well known, there is limited research on sex differences in the use of opioid analgesics for this condition in the ED. In this study we aimed to evaluate sex differences in the administration of opioid analgesics (morphine and fentanyl) and to compare the time to medication administration in patients presenting with acute cardiac chest pain.</p>\n<p><strong>Methods: </strong>This retrospective observational study included adult patients (≥ 18 years of age) presenting with acute cardiac chest pain and confirmed elevated troponin between 2019–2024.

Our goal was to evaluate the association between adolescent substance use, detected via blood alcohol levels and urine drug screens, and trauma-related outcomes at a Level I pediatric trauma center. Most of the literature is focused on adult trauma patients with limited data in the pediatrics.</p>\n<p><strong>Methods:</strong> In this retrospective cohort study, we analyzed data from adolescent trauma patients 13-17 years of age presenting to a Level I pediatric trauma emergency department (ED). Demographic data, Injury Severity Score (ISS), intensive care unit (ICU) admission, hospital length of stay (LOS), and ED disposition were extracted from the Pennsylvania Trauma Systems Foundation Database Collection System, which includes comprehensive information on demographics, clinical characteristics, and outcomes of trauma patients. These data were compared between patients whose alcohol levels and urine drug screening were positive and negative. Our primary outcome measures were ISS and LOS in the hospital and ICU. Our secondary outcome measures were need for surgery, mortality, and disposition from the ED. Specific substances, including tetrahydrocannabinol (THC), benzodiazepines, and opioids, were further analyzed as drugs associated with these outcomes. We performed multivariate regression models to identify independent associations of blood alcohol levels or urine drug screen positivity with trauma severity and ICU admissions. </p>\n<p><strong>Results:</strong> Among 405 adolescents who had toxicology testing done, 11/286 (3.8%) tested positive for alcohol, while 95/377 (25.2%) had positive urine drug screens predominantly for THC (19.9% of the 95 who had a positive screen). Blood alcohol level-positive patients demonstrated significantly lower ISS (P < .001), shorter ICU stays (P. < .01), and shorter overall hospital stays (P< .01) compared to blood alcohol level-negative patients. Conversely, benzodiazepine positivity was strongly associated with higher ISS, increased ICU admissions, and prolonged hospitalization stays. Multivariate analysis showed that older age was associated with increased ISS (β = 0.30 per year, P < .06) and ICU admission (OR 1.16, 95% CI, 1.04-1.28, P < .01). Blood alcohol level and most urine drug screen results were not independently associated with primary outcomes of ISS and LOS in the hospital and ICU, although benzodiazepine positivity was strongly associated with increased ISS (P < .001) and ICU admission (OR ≈ 30, P < .001). </p>\n<p><strong>Conclusion: </strong>Adolescent trauma patients who were positive for benzodiazepines were associated with significantly worse outcomes, emphasizing the need for targeted screening and intervention strategies. Alcohol positivity was paradoxically associated with less severe trauma presentations. These findings highlight the complexity of substance use on adolescent trauma and underscore the importance of nuanced clinical assessments and targeted interventions addressing both substance use and underlying sociodemographic vulnerabilities.</p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

While 61% of respondents reported that they offered contraceptive services less than once a month, 64% reported they were comfortable educating patients on the topic and 51% were comfortable providing prescriptions. Of those comfortable prescribing, 84% stated they would be more comfortable after an educational session, while 58% of those currently not comfortable prescribing believed that education would help (P < .01).

Eight percent of individuals living in the United States have LEP, placing them at risk for language barriers that can adversely affect the quality and safety of their care. Many hospitals lack language-concordant care, especially at the time of discharge. Miscommunication at discharge can lead to adverse health outcomes, including medication errors, poor compliance, and unnecessary return visits to the ED. Our objectives in this study were to evaluate the quality and safety of artificial intelligence (AI)-generated translations of physician-written, patient-specific ED discharge instructions and to assess performance across varying levels of instruction complexity. </p>\n<p><strong>Methods:</strong> Emergency physicians wrote free-form discharge instructions, representing patient-specific guidance, which are typically provided at the time of ED discharge. Four topics were selected: abdominal pain; chest pain; wrist fracture; and vaginal bleeding in pregnancy. These instructions were intentionally developed to vary in linguistic complexity and were assessed using the Flesch Reading Ease and Flesch-Kincaid Grade Level scales. Instructions were translated into Albanian, Brazilian Portuguese, and Vietnamese using the AI-based translation tools ChatGPT-4, Microsoft Copilot, and Google Translate. Translations were evaluated for semantic and syntactic accuracy. Criteria included adequacy, fluency, meaning, and severity on a 5-point scale (1 = lowest accuracy, 5 = highest accuracy). Preference and formality were rated on a 3-point scale (1 = lowest, 3 = highest). The primary outcome was the quality and safety of AI-generated translations of patient-specific discharge instructions. Secondary outcomes included the ability to handle varying instruction complexity. Professional medical translators primarily responsible for the written translation of medical text evaluated and scored the translations for accuracy and quality metrics.</p>\n<p><strong>Results: </strong>Overall adequacy, fluency, meaning, and severity scores were similar across models. ChatGPT-4 (3.79), Microsoft Copilot (3.60), and Google Translate (3.50), showed no statistically significant differences. Albanian translation was an exception, with ChatGPT-4 scoring significantly higher (3.75) than Google Translate (3.19) (P < .001). There were no other significant differences observed for Brazilian Portuguese or Vietnamese. ChatGPT-4 was also found to be the highest rated for Albanian and Brazilian Portuguese. Both Microsoft Copilot and Google Translate produced a total of five potentially harmful translation errors, whereas none were identified for ChatGPT-4. </p>\n<p><strong>Conclusion:</strong> Miscommunication during discharge can lead to negative patient outcomes. This study evaluated ChatGPT-4, Microsoft Copilot, and Google Translate in translating ED instructions into Albanian, Brazilian Portuguese, and Vietnamese. ChatGPT-4 performed best overall and produced no harmful translations, and significantly outperformed Google Translate in Albanian.

Despite this, many insect groups remain poorly investigated in these systems, particularly within the Mediterranean Basin. Fireflies (Coleoptera, Lampyridae), besides their ecological, cultural, and conservation relevance, are no exception. Here, we present the first comprehensive synthesis of firefly occurrence across major and minor Italian islands, integrating standardised nocturnal surveys conducted within the L.U.C.E. (“Lighting up the understudied charismatic fireflies of Europe”) project with validated citizen-science records derived from the iNaturalist platform. This integrative approach enabled a complete assessment of species occurrence, spatial patterns, and the complementary value of structured fieldwork and citizen-generated records. Surveys were conducted in Italy between 2023 and 2025 across two major islands (Sardinia and Sicily) and thirteen small islands. Occurrence data were analysed to quantify taxonomic richness, island occupancy, and the relative contributions of each data source across islands. Overall, we recorded 10 taxa (including species and subspecies) on Italian islands, representing 50% of the firefly species currently recognised at the national level. Species richness and record abundance were significantly higher on larger islands. In contrast, small islands generally hosted one or two taxa, reflecting classic island biogeography patterns and limited dispersal abilities linked to firefly life-history traits. Comparison between data sources revealed a strong complementarity. Citizen-science records provided broad spatial coverage, particularly on easily accessible and frequently visited islands, but often lacked fine taxonomic resolution. Conversely, targeted surveys yielded fewer records overall but were essential for detecting poorly known populations, achieving accurate species-level identification, and documenting rare or previously unrecorded taxa. Notably, the detection of <em>Lampyris pallida</em> on Linosa, confirmed through DNA barcoding, represents the first record of this species for Italy.</span><!--EndFragment--></p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

The goal is to facilitate rapid patient evaluation and improve key operational emergency department (ED) metrics.

Point-of-care ultrasound (POCUS) has been shown to improve patient care and speed diagnosis in a variety of scenarios. Although physicians working within a PIT model must remain mindful of time constraints, POCUS can help identify time-sensitive diagnoses and guide appropriate initial testing during certain encounters. Ocular POCUS can be particularly impactful on timely diagnosis and appropriate deployment of ED resources.</p>\n<p><strong>Case Series: </strong>We present three cases of acute monocular vision loss wherein the PIT physician used ocular POCUS to arrive at the correct initial diagnosis.

However, it is rarely associated with life-threatening lactic acidosis. This generally presents in patients with gastrointestinal upset as a primary complaint. It is most common in patients with underlying chronic kidney disease. Prevention of associated mortality requires early diagnosis and intervention with fluids, bicarbonate, vasopressors, and hemodialysis.</p>\n<p><strong>Case Report: </strong>This is a notable presentation of metformin toxicity, as the 68-year-old male patient presented with an atypical chief complaint of dyspnea and no history of kidney disease. Physical exam was notable for tachypnea and clear breath sounds. Labs revealed anion gap metabolic acidosis from an accumulation of lactic acid and acute renal failure. Other causes of lactic acid metabolic acidosis were considered and ruled out. Nephrology was consulted and pharmacological therapies started as the patient transitioned to the intensive care unit for emergent hemodialysis. He eventually regained renal function and was discharged. His metformin level returned several weeks later significantly elevated.</p>\n<p><strong>Conclusion</strong>: Emergency physicians should maintain metformin toxicity on the differential for patients on metformin presenting with dyspnea and anion gap metabolic acidosis with elevated serum lactic acid concentrations. Other sources of lactic acidosis should be ruled out, and corrective therapies, including renal replacement therapies, should be started immediately.

Our objective was to quantify inter-rater variability of three emergency attending physicians for the clinical diagnosis of UTI, and secondarily to compare the diagnosis made at bedside by the treating clinician with the evaluations of three emergency physician-chart reviewers after the fact.</p>\n<p><strong>Methods:</strong> Chart reviewers read 18 articles on the diagnosis of UTI before retrospectively evaluating a convenience sample of 473 ED encounters where patients received both a urinalysis and urine culture as part of their ED evaluation. The chart reviewers were blinded to the urine culture results, medications administered and prescribed, and to the treating clinician’s diagnoses. Reviewers were asked to rate the likelihood of UTI based on a 0-4 ordinal scale. A “true positive” UTI occurred when the treating clinician diagnosed the patient with a UTI and the urine culture had ≥10,000 colony-forming units (CFU)/mL of bacteria. We considered a “false positive” to be when the treating clinician diagnosed the patient with a UTI, but the urine culture was < 10,000 CFU/mL of bacteria. A “true negative” occurred when the treating clinician did not diagnose the patient with a UTI, and the urine culture was < 10,000 CFU/mL of bacteria.</p>\n<p><strong>Results: </strong>Median patient age was 63 years, 355 (75%) were female sex, 409 (86.5%) were White race, and 207 were admitted to the hospital. The inter-rater agreement among the three independent reviewers was high (κ 0.82-0.85) with intraclass coefficient (2,1) = 0.83. However, the reviewers-to-treating clinician agreement was only moderate in the true positives (treating clinician diagnosed patient with a UTI and the patient had a positive urine culture) and lowest in the false positives (treating clinician diagnosed the patient with a UTI, but the urine culture was < 10,000 CFU/mL with κ values of 0.44 and 0.21, respectively). The variables associated with consensus among reviewers were nitrites, leukocyte esterase, and higher urine white blood cells.</p>\n<p><strong>Conclusion: </strong>There was high consensus among reviewers about the likelihood of a urinary tract infection, but lower consensus when comparing reviewers’ impressions with those of the treating clinician.

In this pilot study we aimed to evaluate the diagnostic performance of AI interpretation of ECGs by comparing its results to those of an experienced emergency physician.</p>\n<p><strong>Methods: </strong>We sourced 20 ECG cases representing common critical conditions from publicly available academic repositories—ST-elevation myocardial infarction, non-ST-elevation myocardial infarction, atrial fibrillation, supraventricular tachycardia, ventricular tachycardia, third-degree atrioventricular block, left and right bundle branch block, hyperkalemia, Brugada syndrome, Wellens syndrome, fusion beats, and torsades de pointes.The AI tool ChatGPT-4 and an experienced emergency physician, who served as the reference (gold standard) interpreter, independently analyzed each case across five key parameters: rhythm and heart rate; cardiac axis; ST/T segment changes; preliminary diagnosis; and emergency management recommendation. Full concordance was defined as complete agreement across all five parameters.</p>\n<p><strong>Results:</strong> Agreement between AI and the emergency physician was observed in 18 of 20 cases (90%). The Cohen kappa was 0.80, indicating substantial chance-corrected agreement. Concordance by diagnostic category was as follows: myocardial infarction (6/6, 100%); arrhythmias including atrial fibrillation, supraventricular tachycardia, and ventricular tachycardia (6/6, 100%); conduction disorders (3/3, 100%); and hyperkalemia (1/1, 100%). Among the atypical or complex ECGs, concordance was 1/1 (100%) for Brugada syndrome, 1/1 (100%) for Wellens syndrome, 0/1 (0%) for fusion beats, and 0/1 (0%) for torsades de pointes. In the torsades case, ChatGPT did not recommend intravenous magnesium sulfate—the standard first-line treatment—despite recognizing the condition.</p>\n<p><strong>Conclusion:</strong> An AI tool demonstrated moderate diagnostic concordance with one experienced emergency physician in interpreting some common ECG findings in the emergency setting. However, discrepancies, particularly in complex cases and critical management recommendations, highlight the need for larger scale investigations. Our findings from this pilot study do not support the independent use of AI for definitive ECG interpretation or emergency management decisions; it should serve as an adjunct tool that enhances rather than supplants human clinical judgment.</p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

We are revitalizing our history and culture surrounding traditional seed varities. The following is a case study in methodology on seed rematriation. In particular, we share the process when it is co-developed between an Indigenous institution and a Federal Research Agency with the same intention to support Indigenous Food and Seed Sovereignty. Nueta Hidatsa Sahnish (NHS) College and USDA-Agricultural Research Service Northern Great Plains Research Laboratory are conducting Indigenous research utilizing participatory action research methods deeply rooted in relationality and respect to support Indigenous Seed Sovereignty through seed multiplication and rematriation. The collaboration aims to support the health of the Traditional Seed Cache located at NHS College by increasing the quantity and quality of seeds available to MHA Tribal members. Through a sharing circle, we have asked the Pawnee Seed Preservation Society, the University of Montana, and Montana State University to share the lessons they learned in seed sovereignty to complement our methodology.

As a collective led mostly by Indigenous women representing a broad span of what is currently known as the United States and Canada, we each are working with and alongside Indigenous communities to reclaim the cultural, spiritual, relational, and ecological protection of future uses of cultural fire.</p>\n<p>Cultural fire includes Indigenous-led fire practices such as cultural burning, fire medicine, ceremonial fire, and ancestral land-based stewardship responsibilities. Outlawed by settlers and state-led agencies, Indigenous peoples understood our relationship with fire was not solely ecological—it was and continues to be cultural, spiritual, relational, and political. With increased extreme weather, settler government agencies are now calling for an increase in cultural burning to mitigate the effects of uncontrolled wildfires and climate- change impacts. As many of our nations across the globe revitalize our cultural fire practices, we are collectively experiencing what we deem a Fire Back movement.</p>\n<p>The reclamation and revitalization of fire practices is being led through Indigenous rematriation (which is community-driven), Indigenous matriarchal-led practices, and relations with the land. Rematriation aims to restore balance and promote healing in Indigenous communities by reclaiming Indigenous knowledges, revitalizing cultural practices and obligations, and supporting Indigenous leadership and decision-making power. We conceptualize “rematriation” to mean the return, revivification, and restoration of our responsibilities and relationalities with fire as our relative. Furthermore, we offer rematriation not in opposition to “repatriation” (a legal term developed under the Native American Graves Protection and Repatriation Act, which aims to return cultural objects to Indigenous peoples)—rather, we offer the term as a balance of societal roles our peoples held in our communities and with our environments since time immemorial.</p>\n<p>This article and the Indigenous fire scholarship curated represent a spectrum of geographies throughout the USA and Canada, offering a conceptualization of “Fire Back” through rematriation to restore rights to the intentional use of Indigenous-led and -informed fire practices. Our framework articulates fire rematriation through the interconnected kinship of people, fire, and planet. It also advocates for cultural fire sovereignty: fire practices, governance, safety, health, and adaptation led and informed by Indigenous peoples, including our scholars, practitioners, and allied researchers meaningfully engaging as partners and supporters.</p>\n<p>Significantly, cultural fire differs from prescribed fire in both process and protocol. To differentiate, we expand on, adapt, and apply the role of cultural safety in relation to rematriating Indigenous fire practices and cultural fire sovereignty. In this context, cultural safety is trauma-informed and can only be defined and assessed by Indigenous peoples, our families, and our communities in the given fire-scape and related institutional setting. Outcomes can range from feeling physically, socially, emotionally, and spiritually respected and safe or safer, to experiencing the absence of racism and discrimination, to feeling that one’s Indigenous culture is acknowledged, appreciated, and incorporated into wildfire management. Furthermore, cultural safety in wildfire management can be recognized at various levels from the microlevel (individual) to the macrolevel (environmental and societal—land, water, place, and geography). Fostering spaces where Indigenous cultural practices are seen, heard, included and respected, relationality is built from cultural safety in fostering equity in the use of Indigenous-led fire practices: facilitating the exercise of inherent relationships and rights by Indigenous peoples, families, nations, and communities in this current Fire Back movement.</p>", "language": "eng", "license": { "name": "Creative Commons Attribution-NonCommercial 4.0", "short_name": "CC BY-NC 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Examined through the lens of Indigenous Archival and Data Sovereignty, this article highlights the major challenges, as well as advances, made by transnational alliances of Indigenous activist groups, professional organizations and individual activists within the United States, Canada, and Australia, focused specifically on how they persevered during the foundational stages of information policy development in their respective counties, as well how they collaborated together to implement new protocols, policies, and procedures at the national, regional, and local level. Through the use of Indigenous research methods, including Indigenous storywork and reflexivity, this work argues that the foundational activist work of Indigenous activists fighting to bring awareness of Indigenous information rights has paved the way for the contemporary work within repositories. These Indigenous transnational alliances show the importance of collaborating on a global scale to assert Indigenous radical resurgence and political sovereignty.

The project, a collaboration between the Lac du Flambeau Band of Lake Superior Chippewa Indians and UW Madison Trout Lake Station, has hosted four seasonal workshops and is expanding to include seasonal internships for program alumni. We discuss the past and current versions of our workshop, synergistic relationships from in-house programs and research projects with the Lac du Flambeau Tribe, engagement and feedback from program alumni, and future plans for the projects and leadership. We conclude by providing suggestions and templates for similar place-based initiatives in other Indigenous lands and encourage field stations to be a place where reconnection and regeneration of land-based pedagogies for Indigenous communities are cultivated. </p>\n<p><!--EndFragment--></p>", "language": "eng", "license": { "name": "Creative Commons Attribution-NonCommercial 4.0", "short_name": "CC BY-NC 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

There is a rise in popular culture regarding Indigenous peoples’ epistemologies, culture, languages, curation, and arts everywhere from New Zealand, the America’s, Africa, Australia, and other parts of the world. Historical fascinations with those systems have often been by and for the perspective of non-natives who exploited and romanticized Indigenous cultures to form their own national identities, write popular books, or make popular movies about their brief time with a tribe. The appropriation of Indigenous cultural and aesthetic motifs extended to Europe, with philosophers such as Jean-Jacques Rousseau and John Locke and literary figures such as Karl May to Dylan Thomas. But now, many aspects of the resurgence arise directly from and for Indigenous peoples around the world expressing their own cultural values. Like any cultural resurgence, it is difficult to trace the precise genesis, however, it only recently became a transcontinental phenomenon, uniting disparate Indigenous peoples in the process. </p>\n<p>This essay offers a theoretical and historical framework for understanding the current global rise in this movement. We argue that the return of the Buffalo to Turtle Island provides one such example of Indigenous cultures and their spiritual relatives overcoming colonial boundaries and addressing the social ills of modernity by rebuilding relationships with each other and the earth.

While the unique political situations of Indigenous nations remain undertheorized in much of the border studies literature, this paper suggests that exploring post-9/11 security changes at the Canada/US border as a form of settler colonialism connects critical Indigenous scholarship with border studies. I theorize the processes of securitization to highlight the surreptitious ways settler colonialism is perpetuated by removing “the Indigenous” as a geopolitical entity. This article focuses primarily on the Coast Salish of Washington and British Columbia and their ongoing attempts to assert a transnational identity that spans the Canada/US border. Examining security changes at the international border demonstrates that securitization of the Canada/US border perpetuates the settler colonial framework by undermining Indigenous sovereignty – unsuccessfully in many cases. Nevertheless, First Nations and Tribes in the Pacific Northwest, and elsewhere across the continent, have collaborated and implemented innovative strategies that resist securitization. In the Pacific Northwest, this includes deploying a nationalism movement that spans the border. The data for this article derive primarily from ethnographic fieldwork with the Nooksack Tribal Nation, Stó:lō Nation, and other Coast Salish collaborators. </p>", "language": "eng", "license": { "name": "Creative Commons Attribution-NonCommercial 4.0", "short_name": "CC BY-NC 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Various past human cultures and recent changes in trade and transportation have played a crucial role in the expansion of some species into insular environments. The snakes present on the Maltese archipelago are particularly emblematic of this complex mix of dispersal events. The European Cat Snake, <em>Telescopus fallax</em> (Fleischmann, 1831), forms a species complex widespread from the Balkans to the Middle East and across many eastern Mediterranean islands, regarded in most of the literature as introduced on the Maltese archipelago. Here we genetically investigated the Maltese populations of <em>T. fallax</em> using the mitochondrial marker Cytochrome b, with the aim of properly identifying their genetic affiliation and tracing their possible origin. The eight sequences obtained from the populations of Malta and Gozo shared the same mitochondrial haplotype and clustered together with the Balkan clade of <em>T. fallax</em>, thereby supporting their affiliation to the currently recognized nominotypical subspecies. The haplotype of the Maltese Cat Snake is identical to that of populations from the western Peloponnese and the island of Skyros (Sporades, Greece). The lack of variability found between the studied populations and some from southern Greece supports the hypothesis that this snake was introduced during historical times. The succession of many small Hellenic communities on the Maltese archipelago over the last few millennia suggests a possible Greek-mediated introduction; however, precisely because of the repeated presence of these influences over time, it is difficult to pinpoint the exact timing of introduction.</span></p>\n<p><!--EndFragment--></p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Some of these species become naturalised and pose a risk to the environment, agriculture, and human health. Insects represent one of the most invasive taxa with several disease vectors as well as agriculture and forest pests. Amongst the latter, <em>Corythucha</em> species are considered emerging pests since their life-history traits and host plant trade are helping their rapid spread. Therefore, early monitoring and reporting of highly invasive insect species are fundamental to implement pest management actions aimed at curtailing environmental and socioeconomic damage caused by these species. To this end, I updated the currently known distribution of alien <em>Corythucha</em> species invading Italy using a citizen-science approach, which is an easily repeatable approach that can be applied to other invasive species. In total, 234 records were retrieved from online databases/platforms, including five from the recently arrived invader <em>C. marmorata</em>. Most observations were made in summer and autumn in the months of August and September. The presence of <em>Corythucha</em> species was confirmed in newly invaded areas of Italy, demonstrating that citizen-science repositories are useful first-line tools to detect biological invasions, thus favouring rapid management.</span></p>\n<p><!--EndFragment--></p>", "language": "ita", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

The authors argue that traditional educational models often fail to prepare learners for “wicked problems,” advocating instead for analogue games as experiential, systems oriented learning environments that cultivate critical thinking, collaboration, and adaptability. The book develops a theoretical foundation for analogue GBL by synthesizing perspectives from experiential learning, play theory, and motivational psychology, including Self-Determination Theory. Particular attention is given to the tactile and social affordances of analogue games, which engage learners in dialogic and embodied forms of learning. The authors also introduce practical frameworks for educational game design, including the TEGA model and the use of Game Design Documents, alongside discussions of established game design frameworks such as MDA, DDE, and the Design-Play-Experience model. While the book offers a rich synthesis of theory and practical guidance for educators, some conceptual areas, such as the ontological foundations of play and deeper exploration of dialogue in analogue gaming, could be further developed. Overall, the text provides a valuable and accessible resource for educators and scholars interested in the design and implementation of analogue game-based learning. </p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

At the end of the week, he presented to the emergency department (ED) complaining of palpitations for a few hours. The patient had no past medical history. His physical examination revealed no pathologic signs except for tachycardia and an irregularly irregular pulse rate. An electrocardiogram showed an irregularly irregular rhythm with a ventricular rate of 128 beats per minute (bpm) (rapid ventricular response) and absent P waves, consistent with atrial fibrillation. The patient was monitored in the ED, and a standard regimen of intravenous amiodarone was initiated for rate control. Approximately three hours after initiation, sinus rhythm returned and his heart rate stabilized at 60 bpm.</p>\n<p><strong>Conclusion</strong>: This case report describes a possible association between diclofenac use and new-onset atrial fibrillation in a young, previously healthy individual.
