The impact of internal labor migration on morbidity rates with temporary disability in the Russian Federation

Introduction. One of the most important indicators of the health of the working population is the incidence of temporary disability. The statistical data do not take into account the temporary labor migration of the population, which distorts the idea of the morbidity of the permanent population at the level of the subjects of the Russian Federation and municipalities. The study aims to carry out a comparative assessment of the temporary disability (ТD) level and rating places of the subjects of the Russian Federation on the basis of statistical indicators "Number of cases of TD" and "Number of days of TD" per 100 employees and calculated indicators per 100 employed in the economy. Materials and methods. The article tells about the use of federal statistical observation data. Specialists have made their own calculations of indicators of the level of temporary disability by the number of cases and days per 100 employed in the economy. A direct ranking was carried out in descending order of all the studied indicators. The authors also conducted a direct ranking in descending order of all the studied indicators and performed a comparative analysis of the rating places of the subjects of the Russian Federation according to the level of temporary disability, according to official statistical data per 100 employees and calculated data per 100 employed. Results. In almost 30% of the subjects of the Russian Federation, significant changes were detected in 20 or more rating places, both with the shift of regions into groups with higher levels and with lower levels of morbidity. Limitations. The materials used in this study did not take into account the gender and age characteristics of morbidity. Conclusion. At the present stage, it is necessary to develop new methodological approaches for the analysis of the temporary disability at the regional and municipal levels, their introduction into the system of social and hygienic monitoring and the system of risk management for public health. The use of the indicator "number of people employed in the economy" to analyze temporary disability at the territorial (regional, municipal) level more accurately reflects the level of morbidity of the permanent population living in the study area. Ethics. The conclusion of the local Ethics Committee is not required for conducting the study.

Analysis of Erythrocyte Parameters in Multiple and Long-Term Blood Donors from Northern Pomerania (Poland)

Background/Aims: Assessment of the levels of vital blood parameters in donors is essential to evaluate their health status, ensure their suitability for donation, preserve the integrity of the circulatory system, and facilitate comprehensive health monitoring. The aim of our study was to analyse the levels of haemoglobin, haematocrit, erythrocyte count, MCV, MCH, and MCHC in 12 groups of first-time donors and experienced donors of both sexes at the John Paul II Regional Blood Donation and Treatment Centre in Słupsk, northern Poland. The donors were divided into three age groups (18-30 years, 31-45 years, and 46-65 years). Methods: Using MANOVA multivariate significance tests, we examined the main effects of donor-related factors (age, sex, donor stage) on morphological blood parameters to evaluate different haematological parameters, such as Hb, Ht, RBC, MCV, MCH, and MCHC, and identified statistically significant relationships between all variables. Results: The multivariate analysis of these three main factors showed that the variation in haemoglobin (Hb) levels accounted for 46% of the explained dependence in this statistical model. In particular, approximately half of the variability in the multivariate statistical analysis was attributed to the role of Hb and haematocrit (Ht). In addition, the β-coefficient values for Hb and Ht were statistically higher in relation to donor sex and donor type (single versus repeat). These β-coefficient values from our data represent the strength and direction of the relationship between the haematological parameters (Hb and Ht) and the specific donor characteristics. A higher β-coefficient indicates a stronger influence of donor sex and donor type on these parameters, suggesting that these factors contribute significantly to the variation in the Hb and Ht levels. Based on our results, the comprehensive analysis of the entire statistical model of metabolic biomarkers revealed the following hierarchy: Hb > Ht > MCHC > MCV > RBC > MCH. The results obtained showed strong statistical relationships, as indicated by the high values of the key statistical indicators in our analysis. The coefficient of determination (R²) showed that the model explained a significant proportion of the variance in the data, while the F-test statistic confirmed the significance of the predictors. Conclusion: These strong statistical dependencies provided a clear justification for selecting this model over others, as it effectively represented the underlying relationships within the data. These statistics help to assess how well the model matches the actual data, thereby helping to reduce the risks associated with blood donation, optimise donor safety, and maintain the quality and efficiency of blood transfusion services.

Label-free assessment of complement-dependent cytotoxicity of therapeutic antibodies via a whole-cell MALDI mass spectrometry bioassay

Potency assessment of monoclonal antibodies or corresponding biosimilars in cell-based assays is an essential prerequisite in biopharmaceutical research and development. However, cellular bioassays are still subject to limitations in sample throughput, speed, and often need costly reagents or labels as they are based on an indirect readout by luminescence or fluorescence. In contrast, whole-cell Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) Mass Spectrometry (MS) has emerged as a direct, fast and label-free technology for functional drug screening being able to unravel the molecular complexity of cellular response to pharmaceutical reagents. However, this approach has not yet been used for cellular testing of biologicals. In this study, we have conceived, developed and benchmarked a label-free MALDI-MS based cell bioassay workflow for the functional assessment of complement-dependent cytotoxicity (CDC) of Rituximab antibody. By computational evaluation of response profiles followed by subsequent m/z feature annotation via fragmentation analysis and trapped ion mobility MS, we identified adenosine triphosphate and glutathione as readily MS-assessable metabolite markers for CDC and demonstrate that robust concentration–response characteristics can be obtained by MALDI-TOF MS. Statistical assay performance indicators suggest that whole-cell MALDI-TOF MS could complement the toolbox for functional cellular testing of biopharmaceuticals.

Качество жизни населения Мурманской области: субъективные оценки и объективные характеристики

The assessment of the population's quality of life is an important analytical tool of the state socio-economic policy, which allows analyzing the current level of regional development, the population's satis-faction with living conditions, making interregional comparisons, determining shortcomings and prospec-tive directions of public administration. At the same time, objective statistical indicators, on which the state management is based, in many respects may not coincide with the subjectively perceived quality of life of the population. In this context, the presented research is particularly relevant and practically significant. The purpose of the research is to identify the problems of development of the Murmansk Oblast, the most industrially and territorially developed region of the Arctic zone of Russia, on the basis of the comparison of subjectively perceived assessments of the quality of life and objective socio-economic characteristics, and to outline ways to solve them. To achieve this goal, the following tasks were solved: the methodology for assessing the subjectively perceived and statistically determined quality of life of the population on the basis of indicators characterizing personal well-being and the quality of the living environment was developed; the subjectively perceived quality of life was assessed on the basis of the author’s methodology including the results of surveys of the population of cities and towns in the Murmansk Oblast; the quality of life of the population of the Murmansk Oblast was assessed on the basis of statistical data of socio-economic development; the data of the obtained assessments were compared, similarities and differences in the satisfaction of the population with personal well-being (as well as with the living environment) and statistical characteristics were revealed; the most important problems of socio-economic development, the resolution of which will improve the quality of life of the population of the Arctic region, were identified.

Carbon Flux Models in a Zonally Dry Tropical Forest Area (Caatinga)

Studies on energy exchange in ecosystems are critical for understanding carbon flows amid different vegetation patterns. In semi-arid areas, comprehending the variability in carbon absorption is essential for quantifying and anticipating the impacts of changes in the caatinga ecosystem. This study aims to calibrate and evaluate models for Gross Primary Production (GPP), Net Ecosystem Exchange (NEE), and Ecosystem Respiration (Reco) in the caatinga biome. NEE measurements were obtained and calculated at 30-minute intervals using EddyPro 3.6 software, from raw data measured at 10 Hz. GPP was estimated by partitioning NEE and Reco, all measured in micromoles of CO2 per square meter per second (μmol CO2m⁻²s⁻¹) using the eddy covariance (EC) tower, installed in a legal reserve at Embrapa Semiárido, in Petrolina, Pernambuco, within a section of the caatinga canopy. Following the measurement of carbon fluxes and ecosystem respiration, field measurements were conducted using a portableFieldSpec HandHeld spectroradiometer to obtain the reflectance of the canopy around the turbulent eddy covariance tower. These measurements were carried out in 2015 in a preserved caatinga area. Multiple linear regression models weredeveloped to estimate carbon fluxes from orbital images, enabling accurate estimation of GPP, NEE, and Reco, using the MODIS/Terra Daily Surface Reflectance product (MOD09GA). The primary results demonstrate the effectiveness of the developed models, particularly the GPP model, which exhibited the best statistical indices (R = 0.97; R² = 0.95; Root Mean Square Error = 0.20). Observations from the EC tower indicated that the models developed to estimate NEE, GPP, and Reco, using visible and near-infrared reflectance data, accurately represented the dry period and effectively captured the phenological aspects of the caatinga ecosystem.

Methodological Aspects of Analysis of Competition in Regional Markets of Services for Children with Disabilities

The modern development of social services markets is aimed at introducing competition mechanisms into them. These trends create the need to develop and use a methodology for assessing competition, taking into account the characteristics of each market. Existing methods for calculating various indices are labor-intensive for social markets and do not take into account their specifics: a significant share of government institutions, a narrow segment of consumers, and significant differentiation in prices for services. The article proposes a methodology for analyzing competition in the market of psychological and pedagogical support for children with disabilities, based on the use of two groups of indicators: objective and subjective indicators. To analyze subjective assessments, a coefficient of satisfaction with the price-quality ratio is proposed. Statistical indicators are used as objective assessments. The proposed methodology was tested using the example of markets for psychological and pedagogical support for children with disabilities in a number of regions of Russia. The results obtained allowed us to draw a conclusion about the state of competition in the markets under consideration and identify “problem” regions. The presented methodology allows us to obtain relatively adequate results of the analysis of competition in the market of psychological and pedagogical support for children with disabilities and can be extended to other markets in the social sphere with appropriate adjustments.

Empirical Bayesian Kriging, a Robust Method for Spatial Data Interpolation of a Large Groundwater Quality Dataset from the Western Netherlands

No single spatial interpolation method reigns supreme for modelling the precise spatial distribution of groundwater quality data. This study addresses this challenge by evaluating and comparing several commonly used geostatistical methods: Local Polynomial Interpolation (LPI), Ordinary Kriging (OK), Simple Kriging (SK), Universal Kriging (UK), and Empirical Bayesian Kriging (EBK). We applied these methods to a vast dataset of 3033 groundwater records encompassing a substantial area (11,100 km2) in the coastal lowlands of the western Netherlands. To our knowledge, no prior research has investigated these interpolation methods in this specific hydrogeological setting, exhibiting a range of groundwater qualities, from fresh to saline, often anoxic, with high natural concentrations of PO4 and NH4. The prediction performance of the interpolation methods was assessed through statistical indicators such as root means square error. The findings indicated that EBK outperforms the other geostatistical methods in forecasting groundwater quality for the five variables considered: Cl, SO4, Fe, PO4, and NH4. In contrast, SK performed worst for the species except for SO4. We recommend not using SK to interpolate groundwater quality species unless the data exhibit low spatial variation, high sample density, or evenly distributed sampling.

Quantitative Structure Photovoltaic Properties Relationship of Coumarin Dyes Derived

The performance of an organic solar cell is strongly influenced by the structure of the photosensitizer. In this work, the open-circuit voltage (<I>V<SUB>OC</SUB></I>) and conversion efficiency (<i>η</i>) of a series of coumarin dyes are quantitatively related to the structure of nine coumarin derivatives. The Quantitative Structure Property Relationship (QSPR) is performed using the statistical method of multiple linear regression. In addition, descriptors determined from the ground state at the Cam_B3lyp/6-31G(d, p) level of theory and from the 2D structure of the molecules are mathematically related to the photovoltaic properties. These VOC and <i>η </i>models are accredited with very good statistical indicators (<I>R<sup>2</sup></I> = 0.906 and 0.918; Q<sub>cv</sub><sup>2</sup>= 0.845 and 0.849; S= 0.045 and 0.112; F = 14.524 and 16.846). These statistical indicators confirm the robustness and performance of the models developed. The results show that Voc improves with decreasing surface tension (<i>ts</i>) and increasing number of cycles (<i>cycle</i>). As for the conversion efficiency of light radiation into electrical energy, it is optimal when the light harvesting efficiency (<i>LHE<sub>th</sub></i>) and the excited state lifetime (<i>τ<sub>th</sub></i>) are high. In conclusion, these models have good predictive capabilities and can be used to predict and explain the open-circuit voltage and efficiency of coumarin derivatives that belong to the same field of application.

Statistical analyses of gender disparities in unpaid work in Georgia

Using data from the Labour Force Survey (LFS) with a quarterly sample size of 6,400 households and the Georgia Time Use Survey (GTUS) covering 3,680 households nationwide, this article investigates gender disparities in unpaid work in Georgia and their impact on individual welfare. Employing international methodologies, we calculated new statistical indicators and refined existing ones, including the improvement of Sustainable Development Goal indicator 5.4.1 (SDG 5.4.1). Regression analysis identified education level as a significant factor influencing unpaid work. Our findings underscore significant gender disparities in unpaid work, leading to heightened workloads and temporary poverty for women. These disparities persist across various demographic factors. This research contributes to understanding the dynamics of unpaid work and its implications for gender equality and welfare.

Prediction and optimization framework of shear strength of reinforced concrete flanged shear wall based on machine learning and non-dominated sorting genetic algorithm-II

Reinforced concrete (RC) flanged shear wall has good lateral strength and stiffness, which has been widely used in building structures. Due to the coupling effect of many factors such as wall section shape, shear span ratio, so the shear performance evaluation of flanged wall is still very limited. This paper proposed a prediction framework for the shear capacity of RC flanged shear walls. A database containing 14 input variables, 1 output variable and 153 samples was constructed to evaluate the prediction accuracy of 11 existing design methods. The Pearson coefficient was used to preliminarily analyze the correlation between variables. The grid search was used to optimize the hyperparameters of 4 machine learning models, and six statistical indicators ( R2, R, RMSE, SD, MAE, and MAPE) were used to comprehensively compare the prediction results of the ML models to determine the best model. On this basis, SHapley Additive exPlanations (SHAP) was used to enhance the interpretability of the prediction models, and the mechanism of the input variables on the shear capacity was quantified. A graphical user interface (GUI) was proposed to guide the engineering design. A multi-objective model (MOO) was established to analyze the trade-off between shear performance and cost, thereby determining the best optimal scheme. The results show that the prediction accuracy of the ML models is better than the existing design methods. The XGB model has the best prediction performance, with R2, R, RMSE are 0.99, 0.99, 118.96, respectively. The SHAP method can effectively enhance the interpretability of the ML models, and tw, lw and f ′c are the key parameters affecting the shear capacity of the flanged shear wall.

Calibration and validation of the AquaCrop model for forage cactus production systems under different management interventions in the semi-arid region of Brazil

Simulation models are useful tools for estimating plant response and contributing to the development of management strategies and yield predictions in crops. This study aimed to calibrate and evaluate the AquaCrop-FAO model for the forage cactus imposed on different cropping systems in the semi-arid region of Brazil. Four experiments were conducted: cactus-sorghum intercropping system with five spacings between plants (0.10, 0.20, 0.30, 0.40 and 0.50 m); cactus-sorghum intercropping system with five spacings between rows (1.00, 1.25, 1.50 and 1.75 m); single cactus with four levels of mulch (0, 5, 10 and 15 Mg ha−1); and single forage cactus with four levels of nitrogen fertilisation (50, 150, 300 and 450 kg of N ha−1). The performance of the model was evaluated using the following parameters: root mean squared error (RMSE); normalised RMSE (NRMSE), coefficients of determination (R2), Nash-Sutcliffe model efficiency coefficient (ME) and the Willmott index of agreement (d). During the calibration stage, the statistical indices pointed to the good performance of the AquaCrop model in estimating dry biomass in most of the cropping systems, with 10 < NRMSE <20; R2 > 0.96 and ME > 0.95. The AquaCrop model showed the best performance simulating systems under different levels of nitrogen fertilisation. Among the intercropping systems, the denser arrangements showed the highest values for simulated biomass.

STATISTICALLY STABLE VERBAL-NOMINAL COMBINATIONS WITH THE COMPONENT ЖИЗНЬ IN THE ANCIENT RUSSIAN CHRONICLES

The article describes statistically stable verbal-nominal combinations with the component ‘жизнь’, functioning in the Old Russian language. The material for the study is an electronic collection of three ancient Russian Chronicles, published on the portal “Manuscript: Slavic Written Heritage” (URL: http://manuscripts.ru/). The study presents a statistical analysis of bigrams, which made it possible to identify statistically significant verbal-nominal combinations with the component ‘жизнь’ and qualify them as expressions that claim stable status. Analysis of the obtained statistical information makes it possible to identify connections between various linguistic elements, determine patterns in the development of certain phenomena, describe the functioning of complex processes in language and clarify the mechanisms of interaction of units in it. This study is carried out using special statistical indicators that allow us to determine the degree of stability of expressions, thereby avoiding subjectivity in assessing a particular construction from the point of view of ideomaticity. To identify collocations in the corpus of the oldest Russian Chronicles, the tools of the Manuscript IAS are used, in particular the n-gram module, which allows you to obtain text combinations with a different number of components. As a measure of association, the T-score measure is used, which allows us to determine how non-random the strength of connection between words in a phrase is. The selected bigrams and their statistical data demonstrate the presence in the Old Russian period of combinations that cannot be called phraseological units in the modern sense, but it is necessary to note their statistical stability in the text, which allows them to be qualified as stable combinations / collocations / statistically stable expressions.

Measuring Data Quality from Building Registers: A Case Study in Italy

Geographic data quality is a complex issue requiring continuous operational improvements. Considering this to be one of the most topical research and technical issues in official statistics and environmental monitoring, this study re-connects the operational dimension of ‘geographic data quality’ with the broader issue of monitoring the quality of official statistics. By estimating the accuracy of public (spatially explicit) data, this study illustrates an operational framework with an exploratory exercise in estimating the geographic data quality characteristic of a specific information source within the official statistical system (i.e., building registry) in a given European country, namely, Italy. The results of this exercise provide a paradigmatic example of profound innovation in the activities of statistical services in Europe and specifically the Italian National Statistical Institute (Istat), transitioning from independent (and poorly connected) field surveys to an integrated system of registries. Since several studies are based on spatially explicit survey units, it is essential to estimate the quality of geographical data, especially those derived from information sources where space is topical information, such as (local, regional, or national) building registers. Thanks to the results of an empirical exercise applied to Italian building registers, the present article will discuss the issue of data accuracy, considered the main issue related to monitoring geographic data quality, from an official statistics’ perspective. Statistical indicators will be proposed for the assessment of systematic and random errors of spatially explicit measures, possibly enabling a quali-quantitative improvement in the semantic content of building registers that address the inherent requirements of official statistics. Such indicators have some positive implications for the entire system of official statistics in Italy and, for generalization, within the European Statistical System.

Enhancing groundwater resource detection in Ahmednagar District through an integrated GIS framework utilizing AHP, SI, and FR models

ABSTRACT Groundwater resources affected by climate change exacerbate groundwater level declines in areas relying on erratic monsoons and finite surface water supplies. This research developed and compared an integrated geographic information system (GIS) with the analytical hierarchy process (AHP), the statistical index model (SI), and the frequency ratio model (FR). Multiple layers of the GIS framework have captured surface and subsurface characteristics, including rainfall, slope, elevation, land use/land cover, soil, geology, and geomorphology. 30% of the 69 wells in the study area are the testing dataset, and the remaining 70% make up the training dataset. Based on AHP, the results show that 35.34% of the region has low potential, 43.47% has moderate potential, and 21.09% has high potential. While SI modeling reveals 9.60, 57.36, and 24.79% for low, moderate, and high potential, respectively, FR analysis suggests 25.50% low potential, 52.74% moderate potential, and 21.60% high potential areas. The superior reliability of the SI model has been indicated by the validation of the GWPZ map using receiver operating characteristic area under the curve values. The results of this study are crucial for planning sustainable water supplies and managing groundwater resources in areas susceptible to climate change and groundwater depletion.

Prediction of groundwater level using artificial neural network as an alternative approach: a comparison assessment with numerical groundwater flow model

ABSTRACT Over-exploitation of groundwater in arid and semi-arid regions requires an understanding of dynamics for effective management strategies. This study uses an artificial neural network (ANN) to predict groundwater levels using initial water level, pumping, and hydrological and meteorological input variables. A sensitivity analysis assessed predictors’ impact on accurate groundwater level prediction. The accuracy of predictions by the ANN model was examined through different performance evaluation criteria and the result achieved is satisfactory as compared to reasonable statistical indicator values. A comparison of results simulated by the ANN model and numerical groundwater flow model (MODFLOW) was carried out and it was found that the prediction of the ANN model was consistently superior to that of the numerical model. Therefore, data-driven models such as ANN can provide better predictions of groundwater level that will aid in groundwater resource management.

Effectiveness of demographic policy measures in addressing population decline in contemporary Russia

Demographic policy is one of the key tasks of almost any state at the present time. It correlates with the solution of pressing problems in the economic and social spheres, directly depends on the state of healthcare, education, migration policy and other factors and directly affects the socio-economic development of both individual regions and the country as a whole. Many Russian and foreign researchers believe that demographic indicators very accurately reflect the socio-economic and political situation of the state. The relevance of the study is due to the fact that for the progressive socio-economic development of any country, positive demographic dynamics are necessary. The main sign of the negative demographic situation that has developed in modern Russia and a number of countries, primarily European, is the growing scale of depopulation (population extinction). The purpose of this work was to analyze the existing demographic policy of Russia and compare demographic trends in Russia and other countries. The work uses methods of statistical data analysis, comparison of statistical indicators of fertility, mortality, natural population decline, migration, marriage rates in Russia and the Republic of Srpska, methods of retrospective analysis, research of the institutional environment created by the action of state and national programs “Demography”, “Providing accessible and comfortable housing and public services for citizens of the Russian Federation”, “Strategy of socio-economic development for the period until 2024”, Presidential decrees, etc. Research has shown that despite measures taken to overcome the demographic crisis, Russia’s population continues to decline. According to the Federal State Statistics Service of the Russian Federation (Rosstat), as of 1 January 2023, 146.45 million people lived in Russia. By 1 January 2046, according to a Rosstat forecast published in October 2023 the country’s population will decrease to 138.77 million people. To solve demographic problems in the Russian Federation, a national project “Demography” was developed and approved. The government has allocated more than 3 trillion rubles for its implementation. However, it is not possible to completely overcome the negative trend. The authors proposed a number of economic and ideological measures within the framework of agglomeration, migration, and family support policies that can be used within the framework of socio-economic development strategies and national programs aimed at overcoming the demographic crisis.

Socio-Economic Impact of Ethnobotanical Appraisal of Traded Medicinal Plants on Local Communities of District Astore (Gilgit Baltistan)

Medicinal plants are the only possible solution to treat various complications of human beings. The local community of district Astore, Gilgit Baltistan are dependent on medicinal plants for their primary healthcare. The present study was conducted to identify and document the medicinal uses of traded medicinal plants and to assess their socio-economic impact and current status in the respective area. A total of 26 traded medicinal plants were explored from the various villages as informed by the experienced respondents. The collected plants were pasted on herbarium sheets for identification purpose. Ethno medicinal uses were also documented and the collected data was analyzed by using statistical indices i.e. Use value, Relative frequency citation, Fidelity level and Pearson correlation coefficient. Questionnaire survey was conducted and 80 respondents were interviewed to assess the socio-economic impact and current status of traded medicinal plants. The most frequent used part of medicinal plant was leaves followed by roots and seeds. The RFC (0.88) and UV (0.98) were recorded highest for Thymus linearis. The Pearson correlation coefficient value between RFC and UV was 0.944, indicating a strong relationship between RFC and UV. Survey results showed that the traded medicinal plants played a pivotal role by enhancing socio-economic condition of local communities. Findings also indicated that the traded medicinal plants are gradually decreasing due to anthropogenic activities like improper method of collection, illegal trade, unsustainable use and lack of protection and conservation measures.
