A BIM-based Tool for Embodied Carbon Assessment using a Construction Classification System

Life Cycle Assessment (LCA) is widely accepted for evaluating a building's environmental footprint. Building Information Modelling (BIM) has become the go-to strategy for LCA during design. Still, despite BIM-LCA automating detailed quantity extraction, challenges persist, such as a lack of standardised geometry modelling and information management and a common language between LCA and BIM data.This study proposes a method to assess embodied carbon from BIM models classified using a construction classification system that provides a data structure, maps BIM objects and environmental impacts in LCA databases and matches different levels of development (LoD) in BIM models. The method was tested on real-world models, resulting in 375 kgCO2e/m2 for the single residential and 426 kgCO2e/m2 for the multi-residential building. These findings revealed its ability to adapt to different LoD and modelling techniques, expedite assessing different design options, and potentially save up to 20 hours of work remodelling.

Undrained shear strength of artificially flocculated clays

The flocculation and sedimentation of suspended clay particles in marine environments are an important process to form natural marine clays. In this study, the process of flocculation and sedimentation is simulated using appropriate flocculating agents in the laboratory. A series of laboratory sedimentation tests are carried out on various floc samples prepared with different concentrations of flocculating agents, and the size and density of flocs are measured and are found to serve as good parameters to characterise the development of flocculation. Multiple series of undrained triaxial compression tests under normal consolidation, as well as under over-consolidation, are then carried out on a slightly flocculated sample and a largely flocculated sample, as well as an ordinary remoulded sample. The values of the undrained shear strength of the flocculated samples are compared with those of the ordinary remoulded sample. The largely flocculated sample exhibits a higher undrained shear strength under normal consolidation as well as under over-consolidation. A comparison with past studies on natural marine clays also indicates that the highly variable values of the undrained shear strength of marine clays can be attributed to the different levels of development of flocculated structures in clays.

The Effectiveness of Climate Adaptation Finance and Readiness on Vulnerability in African Economies

Addressing climate vulnerability remains a priority for economies globally. This study used the panel-corrected standard error (PCSE) methodology to investigate the impact of adaptation financing on climate vulnerability. This analysis examined 52 African countries from 2012 to 2021 while considering their climate adaptation readiness. The impact was also assessed based on the Human Development Index (HDI) categories to reflect different levels of development. The findings showed that adaptation finance considerably influenced climate vulnerability reduction in Africa, particularly in nations with a moderate HDI. However, most countries still need higher levels of adaptation financing, resulting in a small impact on vulnerability reduction. Furthermore, the impact of readiness measures differed by HDI category. Economic and social climate readiness strongly impacted climate vulnerability in high-HDI nations, but governance preparedness was more critical in low-HDI countries. Based on the empirical facts, two policy proposals emerge. First, it is critical to reconsider the distribution of adaptation financing to reduce disparities and effectively alleviate climate vulnerability. Moreover, African economies should consider implementing innovative localized financing mechanisms to mobilize extra adaptation finance. Second, African governments should customize climate readiness interventions based on their HDI levels to improve the achievement of a positive impact on climate vulnerability.

Influence of charging stations accessibility on charging stations utilization

The widespread adoption of electric vehicles has become pivotal in attaining emissions reduction objectives, and the rationale behind designing and situating charging stations determines the unfurling of electric vehicles. This scholarly work fully mines the geographical situational particulars underlying the functioning statistics of charging stations in Beijing during the period from January to March 2016. By incorporating the urban road network, we construct a charging stations accessibility index to investigate the influence of stations accessibility on utilization rates. The findings reveal a substantial positive relationship between the overall accessibility of charging stations and their utilization rates. However, the limited number of charging stations hinders the agglomeration effect from significantly boosting utilization rates. Moreover, the impact of charging station accessibility on utilization rates varies significantly across regions with different levels of development, indicating pronounced heterogeneity. The research conclusions of this paper provide useful suggestions for promoting the rational layout of charging stations.

Tourism Destination Competitiveness Ranking and Tourism Performance

This research note compares the impacts of the macroeconomic condition on the relationship between tourism destination competitiveness (TDC) ranking and tourism performance. This study utilized the cross-country analysis of the World Economic Forum (WEF) Travel and Tourism Competitiveness Index (TTCI) data among 115 countries. Macroeconomic conditions are conceptualized in high-income versus low-income nations, while the WEF TTCI ranking explains the TDC ranking. The Partial-least square-structural equation modelling (PLS-SEM) Multi-Group Analysis (MGA) results showed that TTCI ranking significantly influenced the low-income group’s tourism performance only but not for the developed ones. The results confirm the criticism of the TTCI ranking bias, reflecting the unbalanced competitiveness assessment distribution between advanced and low-income countries. The study findings augment the incomparability among countries on different levels of development and the arbitrary weighting of the TTCI ranking report, which may lead to inaccurate perceptions of the country and incorrect investment decisions.

BALANCED DEVELOPMENT OF INDUSTRIAL ENTERPRISES AND THEIR ANALYTICAL SUPPORT

The modern development of the market economy indicates a decrease in the factors of strengthening and growth of competitive requirements, increased competition at our Ukrainian enterprises, which are rapidly approaching European requirements. One of the important ways to increase the efficiency of the reduction of prices of goods, works and services is to increase the efficiency of production enterprises. The efficiency of quality management of the manufactured products, the adjustment of the production process depends on the adjusted cost accounting. The financial condition is the most important feature of the company's economic activity. The degree of economic attractiveness of the company for persons interested in the functioning of this organization depends on its financial condition. The main disadvantages of costs at a production enterprise are imperfect cost accounting. In production enterprises, there is no specific approach that can be used to see a clear accounting of costs for a production enterprise. In addition, such a problem as control over the cost of production due to insufficient accounting of costs both in the center of financial responsibility and by types of production was revealed. The problem of the different level of development of information technologies is presented at manufacturing enterprises, which testify to the restraining factor of the introduction of more progressive cost accounting methods.

Urban transportation system toughness assessment under New Crown epidemics.

Since the concept of toughness was introduced to transportation systems, transportation system toughness has received extensive attention from researchers in the field of transportation worldwide. In this paper, a methodology for quantifying and assessing the toughness of urban transportation systems is proposed in the context of the New Crown epidemic. Firstly, the definition of urban transportation system toughness in this context is clarified, and the entropy evaluation method is applied to construct the performance curve of urban transportation systems over time. Then, it is proposed to quantify the system's resistance, recovery, and adaptive ability in terms of the change in the cumulative amount of system performance. Finally, the three characteristic abilities of system toughness are organically combined to obtain a comprehensive assessment of system toughness. Example calculations and analyses are carried out in four Chinese cities with different levels of development, and the results show that the performance of urban transportation systems is positively correlated with their levels of development, and all of them fluctuate greatly under the influence of the epidemic, but Wuhan has the strongest resistance and recovery ability of the transportation system, and shows the highest toughness, followed by Lanzhou, Changchun, and Shanghai. The system toughness quantification and assessment methods proposed in this paper provide a reference for research on improving the ability of urban transportation systems to deal with multiple uncertainty disturbances.

Implementing policies to mitigate urban heat islands: Analyzing urban development factors with an innovative machine learning approach

Taiwan is located in a hot and humid subtropical climate. Urban development, building heat emissions, and human activities lead to the urban heat island (UHI) effect in which urban air temperatures are significantly higher than those in the surrounding suburban areas. In this study, the factors contributing to the UHI effect were investigated in a case study of Taichung City, Taiwan by using high-resolution geographic climate data. Geographic Information System tools were used for grid-based spatial data analysis, and a physiological equivalent temperature index map was calculated and overlaid to identify heat zones. The results revealed that environmental factors have complex, nonlinear effects on temperatures in in urban areas; hence, the analysis was challenging. The decision tree algorithm was used to identified key environmental factors contributing to urban heat in areas with different levels of development; a weighting analysis was then performed to select effective urban cooling strategies. Finally, backpropagation neural network models tailored to different development levels were used for simulations to validate the proposed cooling policies. The results of this study were incorporated into the urban planning policies of Taichung City, Taiwan to mitigate the UHI effect and create a more suitable urban living environment.

Проблемы устойчивого развития в аспектах мирового энергопотребления и экологической грамотности населения

The Stockholm Conference of 1972 set a set of tasks for the governments of different countries aimed at reducing the anthropogenic impact on the natural environment. The current economic and environmental activities of modern countries are examined using the examples of India, Germany and Russia. India and Germany, which have economies of different levels of development, have a similar need for traditional heat and power resources to ensure sustainable development of the national economy and the implementation of environmental tasks set for the countries by their leadership. Russia is in an advantageous position, having large reserves of fuel and energy resources, allowing it to be independent in choosing development paths. Aware of its responsibility to future generations, our country is actively pursuing a policy of reducing its impact on the environment. The international community of scientists and experts has articulated the major human impacts in 2022, highlighting global warming, biodiversity loss, deforestation, plastic pollution, air pollution, especially greenhouse gases from agriculture, and poor government governance. There are huge food losses due to overproduction and large amounts of food waste amid nearly a billion hungry people in the world. The problem of “fast fashion” is identified, which leads to the generation of significant amounts of fabric waste, including synthetic ones. The last two problems are associated with excessive consumption of a significant part of the world's population, which contradicts the general interest of the population in the environment. The marketing policy of organizations using images of nature protection, aimed at the emotions of people who do not have a holistic picture of the world, a penchant for critical analysis, or sufficient knowledge in the field of environmental and natural sciences, is called “greenwashing”. Countering this policy, aimed at increasing consumption under the slogans of reducing the anthropogenic impact on nature, should be based on a consistent government policy to increase environmental consciousness, education and upbringing of citizens.

Nonlinear relationships between human development and international student mobility: The prominent role of employment prospects and cultural and linguistic ties

AbstractHigher education is a key global market and considerable literature has focused on investigating the determinants of international student mobility (ISM). However, less is known about the extent to which the relative influence of these factors is moderated by local conditions and vary across origin countries. Drawing on a unique data set of undergraduate applications from the UK Colleges and Admissions Service, we analyse variations in the contextual determinants of ISM flows to the United Kingdom across countries of origin over a 10‐year period (2009–2019). We run a suite of negative binomial gravity models to understand the key influences of ISM and uncover the spatial heterogeneity of these influences. Our findings reveal a nonlinear relationship between the level of development of origin countries and ISM flows. Although countries from higher development levels are more likely to send students to the United Kingdom, there appears to be a dip in applications at the mid‐levels of development. Given the nonlinearity of this relationship, we seek to understand how countries across different levels of development respond to the typical factors that are seen to influence flows of international students. We also see substantial heterogeneity of the influence of different factors for origin countries, with some countries being influenced by employment opportunities and others by cultural and linguistic ties. However, this variation is not necessarily determined by the countries’ level of development. Our findings have implications for policy makers, educators and researchers seeking to navigate and influence global student mobility trends. Our study highlights the need for tailored strategies to attract and retain international students from specific origin countries, recognising the multifaceted nature of ISM determinants.

Influence of university agricultural technology extension on efficient and sustainable agriculture

Agricultural extension, as an important part of modern agriculture, can promote the scientific transformation of the traditional agricultural production model. This paper analysed the impact of university agricultural technology extension on efficient and sustainable agriculture using difference-in-differences model (DID). The results showed that university agricultural technology extension plays a facilitating role by influencing the coordinated development and green development dimensions in efficient and sustainable agriculture; there is a moderating effect of modern agricultural industrial parked in university agricultural technology extension and efficient and sustainable agriculture; there are significant differences in the impact of university agricultural technology extension on efficient and sustainable agriculture across regions and different levels of development. The findings have important implications for evaluating the effectiveness of current university agricultural extension policies and how to further promote university agricultural extension. The study also established an evaluation index system for efficient and sustainable agriculture, explored the mechanism of university agricultural extension in promoting efficient and sustainable agriculture, and enriched relevant theoretical research.

Review of the Uses of Acoustic Emissions in Monitoring Cavitation Erosion and Crack Propagation

Nowadays, hydropower plants are being used to compensate for the variable power produced by the new fluctuating renewable energy sources, such as wind and solar power, and to stabilise the grid. Consequently, hydraulic turbines are forced to work more often in off-design conditions, far from their best efficiency point. This new operation strategy increases the probability of erosive cavitation and of hydraulic instabilities and pressure fluctuations that increase the risk of fatigue damage and reduce the life expectancy of the units. To monitor erosive cavitation and fatigue damage, acoustic emissions induced by very-high-frequency elastic waves within the solid have been traditionally used. Therefore, acoustic emissions are becoming an important tool for hydraulic turbine failure detection and troubleshooting. In particular, artificial intelligence is a promising signal analysis research hotspot, and it has a great potential in the condition monitoring of hydraulic turbines using acoustic emissions as a key factor in the digitalisation process. In this paper, a brief introduction of acoustic emissions and a description of their main applications are presented. Then, the research works carried out for cavitation and fracture detection using acoustic emissions are summarised, and the different levels of development are compared and discussed. Finally, the role of artificial intelligence is reviewed, and expected directions for future works are suggested.

Time to sputum culture conversion and its associated factors among drug-resistant tuberculosis patients: a systematic review and meta-analysis

ObjectiveWe aimed to evaluate the sputum culture conversion time of DR-TB patients and its related factors.MethodsPubMed, The Cochrane Library, Embase, CINAHL, Web of Science, CNKI, Wan Fang, CBM and VIP databases were electronically searched to collect studies on sputum culture conversion time in patients with DR-TB. Meta-analysis was performed by using the R 4.3.0 version and Stata 16 software.ResultsA total of 45 studies involving 17373 patients were included. Meta-analysis results showed that the pooled median time to sputum culture conversion was 68.57 days (IQR 61.01,76.12). The median time of sputum culture conversion in patients with drug-resistant tuberculosis was different in different WHO regions, countries with different levels of development and different treatment schemes. And female (aHR = 0.59,95%CI: s0.46,0.76), alcohol history (aHR = 0.70,95%CI:0.50,0.98), smoking history (aHR = 0.58,95%CI:0.38,0.88), history of SLD use (aHR = 0.64,95%CI:0.47,0.87), BMI < 18.5 kg/m2 (aHR = 0.69,95%CI:0.60,0.80), lung cavity (aHR = 0.70,95%CI:0.52,0.94), sputum smear grading at baseline (Positive) (aHR = 0.56,95%CI:0.36,0.87), (grade 1+) (aHR = 0.87,95%CI:0.77,0.99), (grade 2+) (aHR = 0.81,95%CI:0.69,0.95), (grade 3+) (aHR = 0.71,95%CI:0.61,0.84) were the related factor of sputum culture conversion time in patients with DR-TB.ConclusionPatients with DR-TB in Europe or countries with high level of economic development have earlier sputum culture conversion, and the application of bedaquiline can make patients have shorter sputum culture conversion time. Female, alcohol history, smoking history, history of SLD use, BMI < 18.5 kg/m2, lung cavity, sputum smear grading at baseline (Positive, grade 1+, grade 2+, grade 3+) may be risk factors for longer sputum culture conversion time.This systematic review has been registered in PROSPERO, the registration number is CRD42023438746.

Trends in Living Arrangements Around the World

AbstractMost people coreside with other kin in private households while others live alone. The incidence of coresidence with kin and solo living varies noticeably across societies. Scholars have long theorized about the role of modernization and cultural change for living arrangements, suggesting a trend toward the nuclearization of households (coresidence only with primary kin) or solo living as societies attain higher levels of development. There is little empirical evidence about global variations in living arrangements and about how such variations unfold at different levels of development. Here we address these fundamental questions. Using IPUMS census microdata for 279 samples and 90 countries, we develop a new metric for assessing the part of the lifetime a person can expect to reside with primary kin, nonprimary kin, or alone assuming exposure rates, from birth to death, to the living arrangements observed in a given year. Results show that coresidence patterns differ substantially across societies, with exposure to primary kin alone and to solo living substantially higher at higher levels of development (as measured with Human Development Index [HDI]). They also reveal a sustained decline in coresidence with nonprimary kin and/or with others nearly everywhere, supporting the idea of an increasing importance of nuclear living arrangements. This trend is most pronounced at medium levels of HDI. At very high levels of development, nuclear family coresidence tends to be stalling or is in decline in favor of more time spent living alone and, rather unexpectedly, to a modest increase in exposure to nonprimary kin within the household. We suggest different interpretations for these results.

India’s Distinct but Opposing Patent Model Is Under Pressure: Prospects and Challenges in the Global Arena

The Indian patent model is a powerful and well-balanced model that not only complies with the requirements of the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS Agreement) but also considers domestic needs and national interest. This study endorses India’s approach of fully availing itself of public health flexibilities provided in the TRIPS Agreement. India’s well thought out patent model contradicts with the pro-patentee approaches taken by the European Union, the USA and Japan. This study emphasises the challenges and pressures faced by the Indian patent model because of the closer harmonisation agenda being pushed by some high-income countries through bilateral and multilateral free trade agreements. This study argues that in order to effectively respond to harmonisation demands, India needs to be proactive in terms of building regional coalitions and transmitting its model to other like-minded Association of Southeast Asian Nations (ASEAN) countries with similar interests. This is a viable approach because most of the ASEAN countries, despite different levels of development and industry, are facing similar challenges in terms of universal access to affordable medicines.

WORK VALUES AND ATTITUDES TOWARD THE TECHNOLOGY OF GENERATION Z IN BRAZIL AND GERMANY

Objective: The aim of this study was to analyze the differences related to work values and attitudes toward the technology of Generation Z in Brazil and Germany. Method: The proposed hypotheses were tested in a survey of 122 Brazilian and German participants. The data were analyzed using t-test and logistic regression models. Main Results: The results present differences between Brazilian and German Generation Z, challenging the literature that analyzes Generation Z as a global generation and reinforcing cultural differences between nationalities. The Brazilian sample presents more instrumental and prestige work values and is more positive and less negative regarding technology than the German sample. Relevance/Originality: The paper’s contribution provides evidence of Generation Z’s differences according to nationalities relevant to shaping their relationship with work and technology. The analysis of both constructs is interesting nowadays because of their interrelationship and the current changes in global work boundaries. Theoretical/Methodological Contributions: The literature predominantly presents that Generation Z is a global generation. Comparing participants from two countries with different levels of development provides an insight into their differences regarding work values and attitudes, which can be valuable for business management literature. Practical/Social Contributions: Recommendations for businesses are provided to improve attraction and retention strategies to tackle the shortage of skilled workers. This implies management strategies for firms with multicultural teams.

Fundamentals, Operation and Global Prospects for the Development of Biogas Plants—A Review

As the global demand for renewable energy continues to rise, biogas production has emerged as a promising solution for sustainable energy generation. This review article presents the advantages of biogas technologies (mainly agricultural, based on waste of animal and plant origin) and extensively discusses the main principles of biogas production in the anaerobic digestion (AD). In this respect, the main parameters of the process, which require monitoring and decisive for its efficiency are described, therefore: temperature, pH value, retention time and organic loading rate (OLR). The principles of substrate selection are also discussed and the necessity and advantages of the use of organic waste according to the model of a circular economy and the concept of sustainable development, are indicated. It is emphasized that according to the new European regulations, the crops classified as food cannot be considered energy crops. The part on biogas production is summarised with an explanation of the necessity to treat and purify biogas. Biogas purification is important from the point of view of the efficiency of its conversion into electricity. A special place in this paper is devoted to the design, construction, functioning and operation of biogas plants, based on both scientific and practical aspects. In conclusion of this chapter, the economic aspects and profitability of operating biogas plants are discussed. Cost and benefit analyses are the major tool used for the systematic evaluation of the financial costs and potential benefits associated with the operation of biogas plants. The important fact is that the return on investment can be achieved within a few years, provided the activities are well-planned and executed. In addition to the fundamental issues of the operation of biogas plants, this article presents the global situation regarding the development of biogas plants, discussing in detail the specific needs and limitations on different continents. It is a interesting and extensive part of this article. The global agricultural biogas market is at very different levels of development. Most such installations are located in Asia and Europe. China has the highest number of biogas plants, with more than 100,000 biogas plants, followed by Germany with over 10,000 plants. In addition to the 100,000 biogas plants, China also has a large number of household biogas units, which gives a total of approx. 40 million operating units. The article concludes with a discussion of opportunities and barriers to the development of biogas plants, pointing to: financial issues, access to feedstock, political regulations, public awareness and the geopolitical situation. The most frequently cited reasons for investment failure include economic problems, lack of professional knowledge.

Dimensions of the constitution

The article is devoted to the conceptualization of the dimensions of the constitution as an important direction of modern political and legal research. It was noted that the category “dimension” combines the objective determination of the influence of the constitution on the course of social relations with its utilitarian value.&#x0D; Given the complexity and multidimensionality of society, it can be argued that there can be many dimensions of the constitution. However, it is known that the constitution to one degree or another regulates (consolidates) all four subsystems of the social system: political, economic, social, and spiritual and cultural. Therefore, the most general, system-creating dimensions of the constitution can be only four - according to the number of subsystems of the social system. All of them can be covered by the term “general or general social dimensions”.&#x0D; The author claims that from a legal point of view, we should be primarily interested in those “internal” dimensions of the constitution that characterize the significance of the constitution for the state mechanism and the national legal system. They, again conditionally, can be called “special” or “legal”. The relevant criteria should be sufficiently universal and significant, capable of being applied to states of different levels of development and different historical eras. At the same time, it should be understood that the constitution is only a legal instrument, so it can neither be blamed for a bad political choice nor praised for a good one.&#x0D; In the broadest plan, five main legal criteria for the success of the constitution are proposed – these are its endurance (permanence), legitimacy, the ability to resolve political conflicts in a legal way, the ability to limit agency costs, as well as to promote the production of public goods.&#x0D; The opinion that according to the vast majority of the dimensions listed above, the current Constitution of Ukraine of 1996 demonstrates quite high results, being an example of a modern and effective Basic Law, is justified. The main problem facing the national Constitution in this regard is the problem of limiting the so-called “agency costs”, especially in the area of corruption prevention.

Insights from a modelling analysis of COVID-19 vaccination in the Eastern Mediterranean Region.

Understanding the main determinants of COVID-19 vaccine uptake is critical to increasing vaccine coverage. This is particularly important for COVID-19 vaccine uptake, which has been affected by both demand and supply issues. To understand the links between vaccine uptake and demand and supply issues in the WHO Eastern Mediterranean and UNICEF Middle East and North Africa regions. We collected data through 2 rounds of a repeated cross-sectional phone survey from 11 000 individuals across 16 low- and middle-income countries. We used logit modelling to distil the main characteristics of the 4 vaccination categories (vaccinated, unvaccinated but willing, unvaccinated and undecided, and unvaccinated and unwilling) while also considering vaccine availability. We conducted sub-regional analysis to account for differences in level of development between the low- and middle-income countries. Despite the increase in vaccination coverage from 60.9% at the end of 2021 to 78.3% by August 2022, about 9% were not willing and were not vaccinated during the two rounds of interviews. Our modelling analysis revealed that positive beliefs about safety, effectiveness and side effects of the COVID-19 vaccines were associated with increased odds of being vaccinated or willingness to be vaccinated. Those who did not believe in the safety of the vaccines were less likely to be vaccinated than those who believed in the safety of the vaccines (OR: 0.56; 95% CI: 0.46-0.67). By contrast, negative beliefs about the COVID-19 vaccines increased the probability of being unwilling to be vaccinated. The results from this research offer useful insights into tackling the supply and demand related barriers to COVID-19 vaccination uptake and provides lessons for future health threats.

A new approach to assessing and forecasting the stock of sprat in the Baltic Sea in modern conditions

The aim of this article: analysis of information and software for forecasting of the Baltic Sea sprat stock Sprattus sprattus balticus at 22–32 ICES subdivisions in the context of the suspension of Russia’s activities in the International Council for the Exploration of the Sea (ICES).Methods used: The data of estimates of sprat abundance and biomass by hydroacoustic methods, commercial and biostatistical characteristics of the species were used to assess the stock and predict its catch in the Baltic Sea. Estimation of the sprat stock was carried out using the traditional method of virtual population analysis (VPA) adjusted according to the method of extended survival analysis (XSA) using the internationally approved VPA module software within the framework of ICES and the R software environment. The recruitment calibration program RCT3 (Recruitment calibration) was used for the abundance of recruitment (age 1 year) according to XSA and forecast. A multivariate short-term forecast was carried out at different levels of development of the total allowable catch (TAC) under the MFDP program (Multi Fleet Deterministic Projection). As an alternative, the domestic software «KAFKA» was tested.Novelty: for the first time, estimates of the sprat stock were made in the conditions of limited access of Russian specialists to primary data in ICES in full.Result: modern methodological and informational support of scientific research in the Baltic Sea in the conditions of the suspension of the activities of Russian experts in ICES makes it possible to obtain information in the minimum necessary amount for assessing the stock of sprat and predicting its catch. Modeling with the «KAFKA» software showed satisfactory results.Practical significance: The current level of information support for forecasting the state of the stock and catch of sprat in the Baltic Sea will allow solving a complex of problems of managing this resource in modern conditions.
