Integrated Internet of Things (IoT) Solutions for Early Fire Detection in Smart Agriculture

The integration of internet-of-things (IoT) technologies is proving crucial for optimizing crop management and monitoring in smart farming. The challenges posed by climate change which involve 1) increased pressure on natural resources, and 2) heightened food safety requirements, eventually call for innovative solutions to protect agricultural resources. Early fire detection, in particular, is essential to prevent major damage and ensure the sustainability of agricultural practices. This article presents an advanced IoT architecture for early fire detection. The proposed architecture integrates 1) smoke and flame sensors, 2) a Raspberry Pi for local processing, and 3) the ThingSpeak platform for data storage and visualization. The system is based on a three-layered architecture: 1) the IoT device layer, 2) the cloud layer, and 3) the application layer, enabling real-time collection and analysis of environmental data. Sensors collect real-time environmental data, which is then transmitted to ThingSpeak for storage. The ThingSpeak platform, combined with MATLAB visualization tools, enables continuous monitoring and in-depth trend analysis of historical data. The results show a clear improvement in accuracy and responsiveness in fire detection while contributing to the safety of agricultural resources and more sustainable management. The blend of IoT technologies, real-time data processing, and cloud-based visualization in this proposed detection system represents an important step towards safer and more resilient agriculture in the face of environmental risks.

Fishing for more than shellfish: a systematic review of fish community monitoring of shellfish reefs

Shellfish reefs, characterized by habitat‐forming bivalves, are increasingly recognized as globally significant coastal ecosystems and valuable fish habitats. Shellfish reefs provide structural refugia, foraging grounds, and nurseries for diverse fish communities, including species with socioeconomic value. However, efforts to quantify the value of shellfish reefs as fish habitats are challenged by the limited and fragmented knowledge of published monitoring practices. Here, we systematically assess 116 peer‐reviewed studies to provide a global overview of literature evaluating fishes in these ecosystems. Research was unevenly distributed, with 67% of the studies concentrated in the United States, 61% on restored reefs, and 83% focused on oyster reefs. Few studies have directly compared fish communities between natural versus restored, or intertidal versus subtidal shellfish reefs. Methods to quantify fishes varied based on research objectives, tidal zonation, and targeted subsets of the fish assemblages. Gill nets, substrate trays, and underwater video stations were the most common methods, with 44% of studies deploying more than two methods to survey fish communities. Differences in the monitoring methods, research designs, and variables reported were also synthesized and discussed. From this review, we identified knowledge gaps and monitoring trends in fish community assessments that can guide future shellfish reef research and conservation efforts.

Collaboration to Reduce Sudden Unexpected Infant Death With Child Fatality Review and Outreach.

Sudden unexpected infant death (SUID) is the leading cause of postneonatal infant mortality in the United States, with disproportionately high rates in Baltimore City and Baltimore County in Maryland. This Advocacy Case Study describes the collaboration between the City and County Child Fatality Review teams to decrease infant mortality. B'more for Healthy Babies, formed in 2009 by the Bureau of Maternal Child Health in Baltimore City with the goal of reducing infant mortality through policy change, service improvements, community mobilization, and behavior change has had a sustained effort to respond to SUID. Recognizing that infants born in Baltimore City often reside in Baltimore County (and vice versa), collaboration with Baltimore County has been essential to increasing B'more for Healthy Babies' scope, reach, and effectiveness. Public health messaging campaigns, creation, and dissemination of a "SLEEP SAFE" testimonial video, and Safe Sleep Summits have involved caregivers, healthcare providers, and community partners. Outcomes of this ongoing collaboration demonstrate a decrease in sleep-related infant mortality rates. Our findings also highlight the need for continued, real time monitoring of sleep-related infant mortality trends with a coordinated, multidisciplinary, and crossjurisdictional response. This initiative can serve as a model of cross-sector communication that can be replicated in other similar geographic locations to further reduce SUID.

ORGANIZATIONAL AND FINANCIAL ASPECTS OF DISTRIBUTION MANAGEMENT OF DIGITAL CONTENT

In today's crisis conditions caused by military, financial, economic, social, environmental political upheavals and threats, the role of innovative technologies in trade is growing significantly. First of all, this applies to digital distribution in the book trade. Compared to traditional forms of trade, it does not require extensive infrastructure, large production facilities, or numerous staff. This helps to reduce transaction costs, respond more quickly to changing market conditions and simplify access to international trading platforms. However, the further development of digital distribution requires constant monitoring and analysis of global trends, and implementation of the best domestic and foreign practices to ensure efficient management of trading operations.The purpose of the study is to formulate the main financial and organizational measures to improve the management of digital distribution and increase its efficiency. To achieve this goal, the following tasks were solved: based on scientific publications and statistical data, the author monitored the trends in the development of digital distribution and the e-book market in Ukraine and in the world; analyzed the rank and level of visits to the websites of leading online e-book and audiobook stores in Ukraine; identified external and internal factors that affect the efficiency of digital distribution, in particular, e-books and audiobooks in the current conditions of military aggression and other risks; developed a model for generating revenue for a digital distribution platform.Financial, economic and organizational measures to improve the company's distribution management of digital content are proposed. These include areas of customer incentives and rewards, improved communication with digital goods manufacturers, priority funding for projects to improve the platform interface and mobile application, improved accounting, reporting, operational and strategic planning, and the introduction of artificial intelligence.

Trends and gender differentials in age-specific suicide mortality, 2004-2020, Cyprus

Abstract Background Cyprus is rarely included in international studies of suicide trends and the only published national data is two decades old. In the context of the first National Strategy for Mental Health, this study assessed suicide trends in 2004-2020, spanning the 2008 global and 2012-2013 Cyprus financial recessions, but falling short of the COVID-19 pandemic due to delays in recording. Methods Suicide deaths were obtained from the Mortality Registry (ICD-10, including “undetermined”). Directly standardized rates were calculated for four gender/age groups. Annual change was estimated in Poisson regression models with interaction terms to assess differential trends over time periods. Results There were 560 deaths (4-times more in men, >80% classified as ‘violent’ in both genders). In men, the suicide rate doubled from 4-5 to 9-10 per 100000, with most of the increase prior to 2012, representing 9% annual change (Rate Ratio 1.09, 95% CI 1.03, 1.15; p = 0.002). From 2013, the trend reversed (effect modification p-value < 0.001) with 4% annual decrease (95% CI -9%, 1%). Declines were not uniform across age-groups; rates in males aged 45-64 continued to rise, surpassing the previously high rate in males 25-44. In women, rates presented a declining trajectory from 4-5 per 100000 to 2-3 over this period, widening the gender differential. M-to-F ratio was 5.33 (95% CI 3.46, 8.19) in 2017-2020 compared to 2.73 (1.88, 3.95) in 2004-2008. A shift to violent methods was observed, with hanging now ranking as most common in both females (1 in 3) and males (1 in 2). Conclusions While relatively lower compared to other European countries, the gender differential in suicide mortality has widened in Cyprus, with steep rises in all male age-groups up to 2012 and continuing rises in males 45-64, but declines in female rates over the same period. Further analysis of trends in relation to unemployment and other socio-economic indicators is warranted as well as continuous monitoring of trends. Key messages • After steep rises in suicide across all male age-groups up to 2012, against a declining trajectory in female rates, rates in males 45-64 continued to rise, further widening the gender differential. • The age profiling and shift towards more violent methods in both genders should inform the first National Strategy for Mental Health, while continuous monitoring of trends is warranted.

Urban burden of disease estimation for policy making

Abstract Introduction The Urban Burden of Disease Estimation for Policy Making (UBDPolicy) project aims to estimate the health impacts resulting from urban and transport planning related exposures in nearly 1000 European cities. So far, quantitative burden of disease assessments have estimated premature mortality attributable to the environmental stressors of air pollution, noise, urban heat islands and lack of green space for the year 2015. Regular reporting and trend monitoring of the health impacts associated with urban environments is crucial for assessing the wider impacts of urban and transport planning. Methods For almost 1000 European cities, quantitative Health Impact Assessments (HIAs) will be conducted that employ the comparative risk assessment methodology. Baseline exposure levels of air pollution, noise, urban heat islands and green space will be estimated and preventable health impacts modelled using counterfactual exposure scenarios. Analysis will comprise two components: firstly, the 2018 HIA will incorporate multiple environmental exposures for that year, while the second component will monitor trends at three-yearly reporting intervals covering the years of 2015, 2018, 2021 and 2024. Results Results are intended to shape evidence-informed urban planning and policies throughout Europe. By ranking cities according to environmental exposures and health impacts, cities are encouraged to address challenges and learn from successful urban design and planning policies in other cities. Discussion HIAs serve as an effective tool for identifying the health impacts of current and future urban policies. The provision of burden of disease estimates will provide policy-makers and practitioners robust data for informed decision-making, while estimates over time will allow tracking of changes from implemented policies. To fully harness the potential of cities as key drivers of sustainable and healthy living, robust evidence must be at the forefront of this change. Key messages • A multitude of urban and transport planning pathways contribute toward the health of urban populations. • Compact city designs often promote health, however there are exceptions.

Google Earth Engine application for mapping and monitoring drought patterns and trends: A case study in Arkansas, USA

Drought is a prolonged dry period that can have severe impacts on the environment, human health, economies, agriculture, and energy resources. It can lead to water shortages, ruin crops, dry out forests, and reduce the availability of food and water for wildlife and livestock. The primary objectives of this study are to: 1) quantify the variability and distributions of drought patterns in Arkansas, United States (US), 2) use remotely sensed indices to investigate the correlation between drought and vegetation cover in the area, and 3) develop a cloud-based framework (user-friendly app) to facilitate the assessment of drought impact in Arkansas over the past decades. A correlation analysis was also performed between the Vegetation Health Index (VHI) and meteorological indices to better understand the impact of meteorological drought on vegetation stress. In addition, Mann-Kendall trend analysis was used to assess trends in meteorological drought indices. The results indicate that drought is most prevalent during March and August months. The results of this study revealed that approximately 31% of the study area fell under the four drought classes (i.e., 1% Extreme drought, 4% Severe drought, 9% moderate drought, and 19% mild drought), with spring and the growing season experiencing moderate drought, particularly in agricultural areas, most notably within the Mississippi Alluvial Valley Plain at both state and county levels. In August, approximately 31% of the study area fell under the Four drought classes (i.e., 1% Extreme drought, 4% Severe drought, 9% moderate drought, and 19% mild drought), with spring and the growing season experiencing moderate drought, particularly in agricultural areas, most notably within the Mississippi Alluvial Valley Plain at both state and county levels. This study provides an essential foundation for policymakers, environmental scientists, and agricultural stakeholders aiming to mitigate drought impacts and safeguard against future climate uncertainties.

Relationship between personal anxiety and genes associated with eating disorders in women aged 45-64

Aim. To study the possible relationship between personal anxiety and polymorphic variants of genes associated with eating disorders (rs17782313 MC4R, rs1800497 DRD2, rs9939609 FTO) in women aged 45-64 in Novosibirsk.Material and methods. A random representative sample of women aged 45-64 years (n=1074, mean age, 54,27±0,2 years) was examined in 2003-2005 at the Research Institute of Internal and Preventive Medicine, a branch of the Institute of Cytology and Genetics, within the Health, Alcohol and Psychosocial Factors In Eastern Europe (HAPIEE) project. Personal anxiety was assessed using the Spielberger self-assessment questionnaire included in the protocol of the Multinational Monitoring of Trends and Determinants of Cardiovascular Disease — Optional Psychosocial Study (MONICA-MOPSY), tested at screenings of the World Health Organization (WHO) MONICA program in 1983-1995. The sample for the HAPIEE program was formed at the program data processing center in Prague for each of the collaborating centers in such a way that each respondent was random. From the sample, every second woman (n=537) was selected for genotyping of the FTO rs9939609 variant (n=384); every third woman (n=358) — for genotyping the MC4R rs17782313 (n=279) and DRD2 rs1800497 variants (n=327). Genotyping was performed in the laboratory of molecular genetic studies by the polymerase chain reaction with the analysis of restriction fragment length polymorphism.Results. Among women aged 45-64, anxiety was detected in 58,3%, and in 15,9% of women the anxiety level was high. The homozygous genotype C/C rs17782313 of the MC4R gene was more common among women with high anxiety levels (17,5%) than among women with low and moderate anxiety levels (1,8 and 0,8%, respectively; p=0,001). There were no significant differences in the detection rate of the rs1800497 genotypes of the DRD2 gene among women with different levels of anxiety (p>0,05). The frequency of the A/A rs9939609 genotype of the FTO gene was highest among women with high anxiety levels — 29,5%, compared to participants with low and moderate anxiety levels (15 and 15,3%, respectively; p=0,048). The probability of anxiety among carriers of the C/C+C/T genotypes of the MC4R gene was 1,29 times higher than among carriers of the T/T genotype (p=0,001). Among carriers of the A/A rs9939609 genotype of the FTO gene, the anxiety probability was 2,34 times higher than among carriers of the A/T+T/T genotypes (p=0,008).Conclusion. The association between anxiety and genes of eating disorders dictates the need for diagnosis and subsequent treatment of anxiety and its associated consequences.

Remote sensing and computer vision for marine aquaculture.

Aquaculture, the cultivation of aquatic plants and animals, has grown rapidly since the 1990s, but sparse, self-reported, and aggregated production data limit the effective understanding and monitoring of the industry's trends and potential risks. Building on a manual survey of aquaculture production from remote sensing imagery, we train a computer vision model to identify marine aquaculture cages from aerial and satellite imagery and generate a spatially explicit dataset of finfish production locations in the French Mediterranean from 2000 to 2021 including 4010 cages (average cage area, 69 square meters). We demonstrate the value of our method as an easily adaptable, cost-effective approach that can improve the speed and reliability of aquaculture surveys and enables downstream analyses relevant to researchers and regulators. We illustrate its use to compute independent estimates of production and develop a flexible framework to quantify uncertainty in these estimates. Overall, our study presents an efficient, scalable, and adaptable method for monitoring aquaculture production from remote sensing imagery.

Difference in Risk Factor profile for Abdominal Aortic Aneurysm and Thoracic Aortic Aneurysm

Previous studies suggest partly different risk factor profiles of thoracic aortic aneurysm (TAA) and abdominal aortic aneurysm (AAA), but prospective data are scarce. The purpose of this prospective population-based case-control study was to investigate differences in risk factor profile between TAA and AAA. Participants in two prospective population-based studies, the Västerbotten Intervention Project (VIP) and the Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) study, between 1986 and 2010 underwent cardiovascular risk assessments, including blood samples, oral glucose tolerance test, blood pressure readings and a self-reported health questionnaire. All individuals who were later diagnosed with TAA or AAA were identified. Age, sex, and time-matched controls were selected from the same cohorts, aiming at four controls / case. Adjusted odds ratios for potential risk factors for later diagnosis of TAA and AAA respectively, were estimated by multivariate conditional logistic regression analyses. From total 96,196 individuals with prospectively collected data in the VIP/MONICA cohort, a total of 236 individuals with AAA (181 men and 55 women) and 935 matched controls, and 168 individuals with TAA (115 men and 53 women) and 662 controls were included. The average age at baseline examination was 57.0 ± 5.7 years for AAA cases and controls, and 52.1 ± 8.8 years for TAA cases and controls. Mean time between baseline examination and diagnosis of AAA/TAA was 12.1 and 11.7 years respectively. There was a clear difference in risk factor profile between AAA and TAA. Smoking, hypertension and coronary artery disease were significantly associated with later diagnosis of AAA with highest adjusted odds ratio for a history of smoking (OR 10.3, 95% CI 6.3-16.8). For TAA, hypertension was the only positive risk factor (OR 1.7, CI 1.1-2.7), while smoking was not associated. Diabetes was not associated with either AAA or TAA, neither was self-reported physical activity. In this prospective population-based case-control study risk factor profile differed between AAA and TAA. This suggests a partially different etiology for TAA and AAA.

Hemodynamic Support With the Impella 5.5 Acute Mechanical Circulatory Support Device.

The Impella 5.5 is increasingly used as a bridge to recovery or heart replacement therapies despite lack of clinical trial evidence. We report real-world outcomes and hemodynamic effects of 150 consecutive patients from a single, high-volume center. Primary outcome was incidence of recovery, durable left ventricular assist device (LVAD), or heart transplant compared with incidence of death at 90 days. Secondary outcomes included hemodynamic trends and upgrade to veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support. The composite endpoint occurred in 59.3% and death in 18.8% of patients (incidence rate ratio: 8.1 [95% confidence interval {CI}: 5.4-12.2], p < 0.001). Decreases in pulmonary artery diastolic pressure (PADP) (p = 0.026), estimated pulmonary effective arterial elastance (Ea) (p < 0.001), and vasoactive-inotropic score (VIS) (p < 0.001) occurred during Impella 5.5 support. Pulmonary artery diastolic pressure correlated with estimated Ea (p < 0.001), suggesting improved right ventricle (RV) afterload with left ventricle (LV) unloading. Veno-arterial extracorporeal membrane oxygenation upgrade occurred in 11.3% of patients who had higher baseline right atrial pressure (RAP) (16.0 [9.0-20.5] vs. 9.0 [7.0-12.0], p = 0.022), PADP (28.5 [25.0-31.0] vs. 23.0 [18.0-28.0], p = 0.011), and lower pulmonary artery pulsatility index (PAPi) (1.45 [0.82-3.45] vs. 2.5 [1.65-3.86], p = 0.029). Upgrade patients had higher repeated measures trends in RAP (p < 0.001) and PADP (p = 0.015). The Impella 5.5 improved hemodynamics and effectively bridged to recovery or heart replacement therapies. Co-existing RV dysfunction can be supported on Impella 5.5 with careful hemodynamic trend monitoring.

Overview and Methods for the Youth Risk Behavior Surveillance System - United States, 2023.

The Youth Risk Behavior Surveillance System (YRBSS) is a set of surveys that tracks a broad range of behaviors, experiences, and conditions that can lead to poor health among high school students. The system includes a nationally representative Youth Risk Behavior Survey (YRBS) and separate school-based YRBSs conducted by states, tribes, territories, and local school districts. For the 2023 national YRBS, CDC made changes to the sampling method, survey administration mode, and questionnaire. Specifically, the sampling design added an American Indian or Alaska Native (AI/AN) supplemental sample so that separate, precise estimates could be made for AI/AN high school students, in addition to the usual sample designed to provide nationally representative data for the population of students in grades 9-12. To decrease the time needed to collect and process data, CDC changed the survey administration mode from paper-and-pencil scannable booklets to a tablet-based electronic survey. To provide national data on topics of emerging interest, CDC added new questions to the questionnaire. These new questions assessed social media use, experiences of racism at school, adverse childhood experiences, transgender identity, consent for sexual contact, and unfair discipline at school. Public health practitioners and researchers can use YRBSS data to examine the prevalence of youth health behaviors, experiences, and conditions; monitor trends; and guide interventions. This overview report describes 2023 YRBSS survey methodology, including sampling, data collection, data processing, weighting, and data analyses. The 2023 YRBS participation map, survey response rates, and a detailed examination of student demographic characteristics are included in this report. During 2023, in addition to the national YRBS, 68 site-level surveys were administered to high school students in 39 states, three tribal governments, five territories, and 21 local school districts. These site-level surveys use site-specific questionnaires that are similar to the national YRBS questionnaire but are modified to meet sites' needs. This overview and methods report is one of 11 featured in this MMWR supplement, which reports results from the 2023 national YRBS but does not include data from the 68 site-level surveys. Each report is based on data collected using methods presented in this overview report. A full description of YRBSS results and downloadable data are available (https://www.cdc.gov/yrbs/index.html).

Development of a tool to assess financial advocacy service delivery.

21 Background: In 2023, the Association of Cancer Care Centers (ACCC) Financial Advocacy Network published Financial Advocacy Services Guidelines developed through an expert-led, consensus-driven process (1). The Guidelines provide a framework for equitable delivery of financial advocacy (FA) services to address patients’ financial concerns. The Guidelines cover 3 domains: financial advocacy services and functions, program management functions, and partner engagement functions. ACCC adapted the Guidelines into a Financial Advocacy Services Assessment Tool to help cancer care organizations assess and improve service delivery and to advance research of organization-level FA practices across the U.S. Methods: ACCC convened an expert task force to guide this work. ACCC conducted a scan of implementation science literature and health care organizational assessments to inform the development of a rating system for each of the 43 guidelines. Four service delivery levels were identified, and a score was assigned to each level (Table). The tool was programmed in Qualtrics to provide a total score and average score per guideline for each FA domain and sub-domain. The task force added unscored questions about organizational demographics, barriers, and readiness to enable aggregate research and sub-group analysis. ACCC invited members of the Financial Advocacy Network to participate in a pilot via email invitation and provided opportunities for open-ended feedback. Results: 20 cancer centers participated in the pilot between March-May 2024. 15% were academic institutions and 85% were community-based programs (18% of which are directly affiliated with an academic institution). Respondents reported the tool was easy to use and informative for quality improvement efforts. See Table 1 for total scores for initial pilot. Conclusions: Pilot results reflect that all participating cancer centers are already engaged in some level of FA services. Broader dissemination and analysis is ongoing. The assessment provides centers with a practical resource to assess alignment to guidelines and identify opportunities for quality improvement. Regular review of aggregate results will help ACCC provide benchmarks for areas of service delivery, identify barriers to implementation, and monitor trends in FA staffing. 1.

Older adults’ decisions regarding mobility to age in place in medium- and high-rise multi-storey residential buildings in urban settings: A case study of South East Queensland, Australia

Population ageing and urbanisation requires a more thorough understanding and monitoring of older adult residential mobility trends. Many older adults move to urban areas and previous studies have been carried out on ageing in place in traditional low-rise residential buildings. However, there is little in the literature about the important push and pull factors influencing older adult moves to medium- and high-rise multi-storey residential buildings in urban areas as they age. This case study research considered the housing migration model of push and pull factors used in elderly residential mobility and investigated the older adults' decision-making regarding mobility to age in place in medium- and high-rise multi-storey residential buildings in South East Queensland, Australia. The study revealed how the older adults expressed a desire to age in place in multi-storey residential buildings in urban areas and identified it as an important element of quality of life. Many older adults chose to move house to high density urban areas from low density urban areas between the ages of 65 and 84. The ‘pull’ factor to significantly influence the decisions of movers was a low maintenance property and lifestyle change from a large suburban home whereas the ‘push’ factor was upkeep difficulties of the house related to old age. This study makes empirical contributions to knowledge in ageing residential mobility trends in urban areas and concludes by providing policy recommendations for developing more effective housing, public spaces, transportation, and community activities and services for older adults, including highlighting a number of recommendations for future research.

Seasonality and epidemiological trends in species distribution and antifungal susceptibility of Candida species isolated from various clinical specimens conducted during 2011–2022, Korea: a retrospective surveillance study

Background: As most Candida species cause opportunistic infections, it is helpful for patient care to determine species name of Candida spp. and their distribution in both sterile and non-sterile specimens. We aimed to investigate trends in the distribution of Candida species isolated from a hospital in Korea, along with their antifungal susceptibilities and seasonal variations. Methods: This study was conducted at the Chung-Ang University Hospital and included 8,760 different clinical specimens from March 2011 to December 2022. Identification of the fungal species and its antifungal susceptibility testing were performed using VITEK 2 ID-YST system for six drugs: amphotericin B, caspofungin, fluconazole, voriconazole, micafungin, and flucytosine. Results: The most common fungal species was Candida albicans. The C. albicans positivity rate gradually increased from 2012 to 2022. Since 2020, however, this trend reversed and the non-albicans Candida (NAC) superseded the count of C. albicans. Among the NAC, C. glabrata showed significant increase. When a weekly analysis was performed, C. glabrata was evenly distributed without any noticeable peak; however, the positive rate decreased from late December to early January across all years. Conclusion: Monitoring of future trends should necessarily be continued. Our findings revealed that the positive rate for Candida was the lowest in the months of December and January of the studied years, which can be attributed to environmental factors. However, further research needs to be conducted.

Airline business models as complex systems: assessing component interdependencies through interpretive structural modelling

PurposeThis paper explores the intricate interdependencies among core components of airline business models (BMs). In the airline industry, where BMs are complex systems, a successful BM requires an orchestrated configuration of various components. However, there is a paucity of research in BM literature pertaining to the interrelationships among key components of airline BMs.Design/methodology/approachEmploying interpretive structural modelling, we gathered input from experts in Iran to assess the driving power and dependency of elements within airline BMs.FindingsOur findings highlight the significance of operating environment conditions and competitive market dynamics as pivotal external components shaping the foundational structure. Value proposition, customer relationship management, and process monitoring are crucial linkage components that drive power and dependency. Notably, capturing value is positioned with the highest dependency.Practical implicationsWe utilised the ISM technique to visualize interdependencies within airline business models, aiding strategic decision-making. Our findings suggest aligning business and operational strategies with market needs ensures effective value creation and capture, maintaining competitive advantage in the airline industry. In addition, our research reveals critical factors affecting value creation and capture, emphasising monitoring the operating environment and competitive market, and strategically managing value propositions and customer relationship initiatives in the airline industry. We advise adapting business models to external changes for sustained growth and recommend regular monitoring of industry trends and customer expectations.Originality/valueFramed within complexity theory, these insights offer valuable perspectives on identifying and situating critical BM components in the airline industry. The practical implications derived from this study serve as strategic tools for airline managers and potential investors to optimise the design of their airline BMs.

Eco-toxic Risk Assessment of microplastics in water and sediment across Nigeria Offshore, Gulf of Guinea.

Globally, the environmental impacts of microplastics (MPs) as emerging pollutants have drawn a lot of attention. This study aimed to assess the distribution and associated potential ecotoxic risk of MPs in the water and sediment of Nigeria's offshore waters. Water and sediment samples were collected from sixteen (16) stations in October 2023 and analysed using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy and stereomicroscopy. For physical characterization, the composition of MPs in sediment and water was 73 particles/kg and 48 particles/L, respectively, while the ATR-FTIR composition at the Eastern Zone (EZ) was 705 particles/L and 1033 particles/kg, the Central Zone (CZ) was 212 particles/L and 338 particles/kg, and the Western Zone (WZ) was 223 particles/L and 218 particles/kg. The identified MPs shapes were filaments, plastic films, fibre, and microbeads. Polychloroprene (CR) (18.10% and 16.86%) at EZ and CZ and polyvinyl alcohol (PVA) (20.64%) at WZ were most abundant in sediment, respectively. In comparison, PVA (22.3%, 22.2%, and 21.08%) was most abundant across EZ, CZ, and WZ in water. The polymer-based plastic contamination factors (ppCf) and pollution load index (pPLI) showed low contamination and pollution load, and the polymer risk index (pRi) showed medium and low risk in water and sediment, respectively. The polymer ecological risks index (pERI) showed a high-risk level (pERI: 1,001-10,000) in water and sediment across the EZ, CZ, and WZ of the Nigerian offshore waters. In marine environments, an extensive environmental monitoring program and trend forecasting for microplastics are crucial. This study will provide theoretical and technical support for developing efficient legislation or policy on the prevention and control of plastic pollution.

Population size, HIV prevalence, and antiretroviral therapy coverage among key populations in sub-Saharan Africa: collation and synthesis of survey data, 2010–23

Key population HIV programmes in sub-Saharan Africa require epidemiological information to ensure equitable and universal access to effective services. We aimed to consolidate and harmonise survey data among female sex workers, men who have sex with men, people who inject drugs, and transgender people to estimate key population size, HIV prevalence, and antiretroviral therapy (ART) coverage for countries in mainland sub-Saharan Africa. Key population size estimates, HIV prevalence, and ART coverage data from 39 sub-Saharan Africa countries between 2010 and 2023 were collated from existing databases and verified against source documents. We used Bayesian mixed-effects spatial regression to model urban key population size estimates as a proportion of the gender-matched, year-matched, and area-matched population aged 15-49 years. We modelled subnational key population HIV prevalence and ART coverage with age-matched, gender-matched, year-matched, and province-matched total population estimates as predictors. We extracted 2065 key population size data points, 1183 HIV prevalence data points, and 259 ART coverage data points. Across national urban populations, a median of 1·65% (IQR 1·35-1·91) of adult cisgender women were female sex workers, 0·89% (0·77-0·95) were men who have sex with men, 0·32% (0·31-0·34) were men who injected drugs, and 0·10% (0·06-0·12) were women who were transgender. HIV prevalence among key populations was, on average, four to six times higher than matched total population prevalence, and ART coverage was correlated with, but lower than, the total population ART coverage with wide heterogeneity in relative ART coverage across studies. Across sub-Saharan Africa, key populations were estimated as comprising 1·2% (95% credible interval 0·9-1·6) of the total population aged 15-49 years but 6·1% (4·5-8·2) of people living with HIV. Key populations in sub-Saharan Africa experience higher HIV prevalence and lower ART coverage, underscoring the need for focused prevention and treatment services. In 2024, limited data availability and heterogeneity constrain precise estimates for programming and monitoring trends. Strengthening key population surveys and routine data within national HIV strategic information systems would support more precise estimates.

Трудовые ресурсы в условиях военной опасности как ключевой фактор повышения промышленного потенциала

The article examines the problem of mobilising the industrial potential of Russia in terms of the growing military danger during SMO under decrease in the demographic and labour potential of the Russian Federation. The authors emphasize the effective involvement of labour resources is a key element for development of the industrial potential. Those are necessary to counter the increasing escalation of the military conflict and the desire of Western countries for military and political defeat of Russia. However, the reduction of labour potential and the aging of the population can cause serious socio-economic and political problems. A liberal approach to migration poses long-term threats to the State. Unregulated migration processes will inevitably cause an increase in unemployment, a decrease in the share Russian nation itself, loss of national identity, social tension, and cultural, ethnic, and religious conflicts. It requires a thorough systematised approach and effective monitoring of demographic trends. The state should find a balance between attracting labour from outside and increasing its own labour resources. It also should provide the rational use of existing labour resources.

The incidence and trends of proteinuria, azotemia and hypertension in cats receiving toceranib phosphate.

This retrospective study aimed to determine the incidence and trends of proteinuria, elevations in serum creatinine and urea, and systolic blood pressure in cats undergoing treatment with toceranib. In total, 32 cats treated with toceranib for malignancies were analyzed. Cats were included if urinalysis and urine protein:creatinine ratio (UPC) measurements were available at 28 days (T1) and 56 days (T2) after starting the treatment. Cats with concurrent lower urinary tract disease, including urinary tract malignancy, were excluded. Friedman's ANOVA compared variables between time points, and the Spearman test assessed the correlation between treatment duration and UPC. The median starting dose of toceranib was 2.68 mg/kg (range 1.7-3.9). In total, 15 (46.9%) cats received concurrent non-steroidal anti-inflammatory drugs. The most commonly treated tumors were oral squamous cell carcinoma (n = 10) and mast cell tumor (n = 5). None of the 32 cats developed progressive proteinuria or azotemia during the follow-up period (median 56 days; range 56-336). Notably, UPC and serum creatinine were significantly lower at T2 compared with baseline (P = 0.012 and 0.001, respectively). Among the four cats with baseline proteinuria, UPC decreased over time with or without concurrent telmisartan treatment (n = 2). All four of these cats experienced a reduction in tumor size with toceranib concurrently with their decreased UPC. There was no significant correlation between UPC and the duration of toceranib treatment (P = 0.089). Blood pressure was not significantly different over the assessed time points. The incidence of proteinuria, renal azotemia and hypertension in cats treated with toceranib for neoplasia appears to be low. Toceranib may be a viable treatment option even in cats with pre-existing proteinuria or renal disease, with careful monitoring of trends recommended.
