ENSO and PDO related variability in seasonal range prediction for the Bolivian Altiplano region in South America
Authors:   , Rojas Murillo Katherine
Published: September 2024

This study uses the methodology of some experiences in seasonal range prediction related to El Nino-Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO) in North America. Previous studies (e.g Garreaud and Aceituno 2001; Vuille and Keimig 2004) in the Bolivian Altiplano focused on interannual variability of DJF precipitation as the EN (El Nino) phase was related to droughts, but the ENSO influence over the region is more complex. For this study monthly precipitation, maximum and minimum temperature from 1979 to 2015 are used to study how ENSO and PDO influence the climate conditions in the Bolivian Altiplano. A power spectra analysis confirmed the periodicities associated to ENSO and PDO. Further, an analysis of variance and the frequency distribution calculation per PDO and ENSO phase were applied using standardized anomalies. The differences between distributions were tested using Chi-squared goodness of fit. Our results suggest an influence of PDO over ENSO, displaying dry anomalies for DJF (Dec-Jan-Feb) in EN/PDO(+) in agreement with previous studies, and wet anomalies for SON (Sep-Oct-Nov) in NU (Neutral)/PDO(+). For maximum temperature, a reduction in cold anomalies during EN/PDO (-) along the year was observed with greater warm anomalies in JJA (Jun-Jul-Aug), SON, and MAM (Mar-Apr-May). Similar results were observed for PDO influence over the NU phase and minimum temperature results displayed more variation within the stations. Finally, an upper-level circulation analysis and changes in the jet stream were observed. Strengthened jet cores were observed in the current PDO and the coupling of two jet streaks enhances the convergence zone upstream of South America. These results would allow production of seasonal forecasts based on ENSO and PDO using upper-level information and surface meteorological information.
Evaluations of driftable fractions of dicamba and 2,4-D to selected herbaceous and woody plant species
Authors:   , Dintelmann Brian Richard
Published: September 2024

Commercialization of 2,4-D and dicamba-resistant cotton and soybean has given producers another mechanism of action to control herbicide resistant weeds. As a result of the adoption of this technology, off-target movement of 2,4-D and dicamba onto nearby sensitive broadleaf species is a major concern for specialty crop growers, homeowners, organic producers, and commercial growers of ornamental plant species. Two separate studies were conducted in 2017 and 2018 to determine the sensitivity of select herbaceous and woody plant species to driftable fractions of 2,4-D or dicamba with or without glyphosate. In the herbaceous plant study, three driftable fractions of 1/10, 1/100, and 1/300th of the fully labeled rate of 2,4-D, 2,4-D plus glyphosate, dicamba, and dicamba plus glyphosate were applied to begonia, coleus, geranium, impatiens, marigold, petunia, vinca, and zinnia. Based on visual injury assessments recorded 28 days after treatment (DAT), coleus was found to be the most sensitive species to driftable fractions of all herbicides. It was also found that marigold and geranium had a greater sensitivity to treatments containing 2,4-D but, coleus and zinnia had a greater sensitivity to treatments containing dicamba. In the woody plant study, the same herbicides were applied but at different fractions corresponding to 1/2, 1/20, and 1/200th of the full labeled rates. Herbicide treatments were applied to apple, crabapple, dogwood, elderberry, elm, grape, hydrangea, maple, oak, pecan, redbud, rose, raspberry, strawberry, sweetgum, viburnum, and walnut plants. Visual injury assessments along with shoot length measurements and tree trunk diameter indicate that grapes were the most sensitive species to all herbicide treatments while hydrangea was the least sensitive. In addition, walnut, grape and elm were found to have a greater sensitivity to 2,4-D while apple, maple, and peach had a greater sensitivity to dicamba. Both studies found that as the herbicide rate increased, greater visual injury, and greater reductions in height and dry biomass or trunk diameter and shoot length were observed. Furthermore, when glyphosate was applied with either 2,4-D or dicamba at the high rates, visual injury increased for most plant species. While the lowest rates of herbicides applied in these studies did not cause significant reductions in height, dry biomass, shoot length or tree trunk diameter, visual injury was still observed for some species. Since many of the species investigated in these studies are fruiting or ornamental plants, it is likely that even the low levels of injury would not be tolerated by homeowners or commercial growers.
Picturing race in local newspapers
Authors:   , Huoppi Peter
Published: September 2024

The American news media has been criticized for failing to accurately reflect the country's racial diversity. Previous research has found that large broadcast and print news outlets overrepresent the White population, while minority populations are underrepresented and largely confined to stereotypical roles. The purpose of this study is to assess whether smaller local newspapers, which remain an important source of news and information to the communities they cover, accurately reflect the racial diversity of those communities, and whether the inclusion and portrayal of different races have changed over time. Using samples of four constructed weeks from five one-year periods between 1980 and 2016, a content analysis of local news photographs was conducted for six daily newspapers. The population appearing in each newspaper was compared with the local population as measured by the U.S. Census. Additionally, inter-group comparisons were made to determine whether members of certain races were overrepresented in the stereotypical roles of athlete, criminal, and entertainer. Results showed that White subjects were generally overrepresented, while members of other races were underrepresented. At some publications, representation of Black subjects has become more accurate over time, while the underrepresentation gap for Hispanic subjects has widened. Results for representation in stereotypical roles were more mixed, with Black subjects overrepresented in the role of athlete.
Impact of selective motor neuron death on hypoglossal motor neuron survival and tongue morphology in a novel model of dysphagia
Authors:   , Lind Lori Ann
Published: September 2024

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Amyotrophic lateral sclerosis (ALS) is a devastating disease characterized by the progressive loss of motor neurons and paralysis of the muscles they innervate. Hypoglossal motor neurons supply the tongue and seem particularly vulnerable to this disease. As a result, tongue weakness is often detectable at diagnosis, and most patients with ALS eventually develop dysphagia (difficulty swallowing). Dysphagia is associated with reduced quality of life and increased mortality secondary to malnutrition, dehydration, and aspiration pneumonia. Despite the severity of the problem, dysphagia has seldom been studied in animal models of ALS. Current models are challenging to analyze because 1) the rate and amount of hypoglossal motor neuron death is inconsistent amongst individuals, and 2) the degeneration of neurons is not limited to those involved in swallowing. To address these issues, we have developed an inducible rat model of dysphagia using intralingual injections of cholera toxin B conjugated to saporin (CTB-SAP) to cause the selective death of hypoglossal motor neurons. All Sprague-Dawley rats in the study received intralingual injections of either CTB-SAP (25 [microgram]) or CTB unconjugated to saporin (controls) and were then evaluated 9 days later. CTB-SAP treated rats showed deficits in hypoglossal motor neuron survival, hypoglossal motor output, lick rate, swallow rate, and tongue muscle fiber size (genioglossus muscle). We thus conclude that this inducible model mimics several aspects of dysphagia seen in ALS and will provide a useful tool for testing therapies aimed at preserving swallowing function in these patients.
Ablation of conceptus PTGS2 provides a new understanding of early pregnancy events in the pig
Authors:   , Pfeiffer Caroline Anne
Published: September 2024

Pig conceptuses produce and secrete estrogens (E[2]), interleukin 1 beta 2 (IL1B2), and prostaglandins (PGs) during the period of rapid trophoblast elongation and establishment of pregnancy. Previous studies established that IL1B2 is essential for rapid conceptus elongation (Whyte et al., Proc Natl Acad Sci USA 2018), whereas E[2] is not essential for conceptus elongation or early maintenance of the corpora lutea (CL) (Meyer et al., 2019). Prostaglandin synthase 2 (PTGS2) expression increases during early pig conceptus development along with production of PGs. Blastocysts express PTGS2 but not prostaglandin synthase 1 (PTGS1) during early development. To evaluate the role of conceptus PTGS2-derived PGs in early pregnancy, CRISPR/Cas9 gene editing was used to create a deletion in exon 1 of the PTGS2 gene. Both PTGS2[+/+] and PTGS2[-/-] embryos were generated using edited fibroblast cells and somatic cell nuclear transfer. Culture media from PTGS2[+/+] and PTGS2[-/-] blastocysts was collected at day 7. Total PG was substantially lower (P < 0.0001) in the culture media of PTGS2[-/-] compared to PTGS2[+/+] blastocysts. PTGS2 was detectable by immunolocalization in PTGS2[+/+] but absent in PTGS2[-/-] blastocysts. Next, PTGS2[+/+] and PTGS2[-/-] blastocysts were transferred into the uterus of surrogate gilts, and the reproductive tract was collected on either day 14 or 17 of pregnancy. Elongating and filamentous type conceptuses were recovered from the uterine lumen by flushing. The conceptuses were cultured for 3 hours to determine overall PG production. Total PG was lower (P < 0.0001) in media of PTGS2[-/-] conceptuses compared to PTGS2[+/+] conceptuses. However, total content of prostaglandin E[2] (PGE[2]) and prostaglandin F[2alpha] (PGF[2alpha]) in the flushings of the uterine lumen containing either PTGS2[-/-] or PTGS2[+/+] conceptuses were not different (P = 0.99 and P = 0.15, respectively). Next, PTGS2[-/-] blastocysts were transferred into surrogate gilts to assess pregnancy establishment beyond 17 days. Of note, pregnancy was maintained beyond day 30 in gilts gestating PTGS2[-/-] embryos. Thus, conceptus-derived PGs do not have a biological role in early pregnancy in terms of conceptus elongation and pregnancy establishment.
Modeling social connectivity and the spread of the 1918-1919 flu through Inupiat and Yup'ik communities of western Alaska
Authors:   , Murray Megan
Published: September 2024

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The spread of infectious disease among human populations is heavily influenced by social relationships and interactions between humans. This project examines the role of social connectivity and residence patterns in determining differential rates of mortality among the Inupiat of the Seward Peninsula and Yup'ik of the Yukon-Kuskokwim Delta in Western Alaska during the 1918-19 influenza pandemic. Despite similar geography, subsistence patterns, and social environments, the severity of the pandemic varied markedly between these groups, with mortality rates on the Seward Peninsula as high as 90 percent and those among the Yup'ik only reaching 32.3 percent. Historic and ethnographic reports on the social organization and kinship systems of the Inupiat and Yup'ik demonstrate marked differences between the two groups in social and community organization, as well as kinship systems. Specifically, the Inupiat communities were shown to have high levels of community connectivity compared to the Yup'ik. The historic accounts were used to construct a social network model that allows analysis of social connectivity as a factor of influence in the severity (or lack thereof) of the 1918 influenza outbreaks seen in these regions. Simulation results, however, suggest that the variations in organization between the two cultural groups included in this model were not enough to create statistically significant difference in epidemic outcomes and that further examination of possible model deficiencies and the factors influencing flu severity in the Seward Peninsula is necessary.
Peptide amphiphile micelles vaccines for cell-mediated immune response induction
Authors:   , Rygelski Brett
Published: September 2024

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Vaccinology research looks to improve upon current formulations by enhancing their immunogenicity and safety. In the quest for an alternative solution, researchers have turned to subunit vaccines due to their potential scalability, price, and increased safety. Peptide amphiphile micelles (PAMs), have been found to be an exciting delivery vehicle to enhance the immunogenic potential of subunit vaccines. This research focuses on exploring the capability of PAMs to induce cell-mediated immune responses to complement previous research which has demonstrated their antibody-mediated induction capacity. Materials characterization studies confirmed that peptide amphiphiles (PAs) comprised of a lipidated ovalbumin T cell antigen (OVA[CytoT] - SIINFEKL) form spherical and short cylindrical PAMs which can be complexed with CpG adjuvant via electrostatic interactions. Ex vivo analysis of animals vaccinated with CpG-modified antigenic PAMs showed an increase in OVA[CytoT]-specific CD8[+] T cell populations in draining lymph nodes in a charge-dependent manner over traditional peptide vaccine formulations. Additionally, studies investigating lymphocytes re-stimulated with OVA[CytoT] peptide in vitro showed a similar response to the ex vivo experiment with less charged micelles inducing greater IFN-[gamma]+ CD8[+] T cells in both the draining lymph node and spleen. This research demonstrated the ability of adjuvant-associated PAMs to improve antigen-specific cell-mediated immune responses and demonstrates a need for future work determining the importance of creating fundamental design rules for charge complexed multicomponent micelle vaccines
Smartphone-based molecular sensing for advanced characterization of asphalt concrete materials
Authors:   , Davami Sayedomidreza
Published: September 2024

Pavement systems deteriorate with time due to the aging of materials, excessive use, overloading, climatic conditions, inadequate maintenance, and deficiencies in inspection methods. Proper evaluation of pavement conditions provides important decision-support to implement preventative rehabilitation. This study presents an innovative smartphone-based monitoring method for advanced characterization of asphalt concrete materials. The proposed method is based on deploying a pocket-sized near-infrared (NIR) molecular sensor that is fully integrated with smartphones. The NIR spectrometer illuminates a sample with a broad-spectrum of near-infrared light, which can be absorbed, transmitted, reflected, or scattered by the sample. The light intensity is measured as a function of wavelength before and after interacting with the sample. Thereafter, the diffuse reflectance, a combination of absorbance and scattering, caused by the sample is calculated. This portable smartphone-based NIR method is used to detect asphalt binders with various performance grading (PG) and aging levels. To this end, a number of binder samples are tested in a wavelength range of 740 to 1070 nm. The results indicate that asphalt binders with different grades and aging levels yield significantly different spectrums. These distinctive spectrums can be attributed to the variations of binder components such as saturate, asphaltenic, resin, and aromatic. Furthermore, the molecular sensor is successfully deployed to detect and classify asphalt mixtures fabricated with a various binder and recycled material types such as styrene-butadiene-styrene (SBS), ground tire rubber (SBS), engineered crumbed rubber (ECR), reclaimed asphalt pavement (RAP), and recycled asphalt shingles (RAS). The proposed monitoring technology is not only a viable tool for asphalt material characterization but also a cost-effective platform capable of transforming the current physical and chemical methods for civil engineering material characterization.
Estimation of dynamic detector confidence thresholds in SAS imagery using mixture models
Authors:   , Dale Jeffrey
Published: September 2024

As machine learning has matured over the years, more and more safety critical tasks have been entrusted to computers. Automated target recognition (ATR), the problem of identifying explosive hazards on the sea?oor, is one such task that is moving toward human-supervised, and eventually, completely human-free methods. The ATR problem inherently su?ers from extreme class imbalance, in that the likelihood of ?nding an explosive hazard in a given region of sea?oor is small, but the penalty for overlooking such an explosive hazard is life threatening. In this study, we develop and test an unsupervised suppression methodology based on the con?dences obtained from an existing prescreening algorithm, the combined RX detector. By treating the unlabeled set of prescreener con?dences as a mixture of Laplace-distributed random variables, we can estimate the parameters of the mixture components and use this information to compute a robust threshold in prescreener con?dence, below which it is safe to discard the associated ROI as benign.
The impact of wood pellet manufacturing on United States southern timberlands
Authors:   , Sudekum Houston
Published: September 2024

Global wood pellet production grew from an estimated 1.7 million metric tons in 2000, to 35.4 million metric tons in 2018. U.S. mills established over this period account for a large share of new supply triggered by renewable energy targets set by the European Union (EU). There is concern over the potential impacts of exponential growth in wood pellet supply on US forests. We offer a systematic quantitative analysis to assess the effects of wood pellet production on forest conditions within wood pellet mill procurement areas. We rely on plot-level information from the US Forest Inventory and Analysis (FIA) database to estimate changes in forest conditions (e.g. trees per hectare, carbon in trees, cubic-meter volume) between inventory years 2000 and 2017 across Southeastern US States. Using spatial analysis and panel-regression for samples of timberland plots we attempt to discern pellet production effects associated with pellet mill size and location. Propensity score matching was used as a resampling technique to select a subset of FIA plots to control for the non-random process of pellet mill sitting. Panel regression models controlled for various anthropogenic and natural factors to measure the net impact of wood pellet production on average plot-level forest conditions. Overall, we find increased carbon stocks and some evidence of increased removals associated with wood pellet production. This research will contribute to a growing body of knowledge related to the sustainability and future prospects of wood energy and wood pellets.
Esquire magazine, presidential politics and hegemonic masculinity

Esquire magazine is one of the premiere men's magazines in the U.S. and has a long history of reporting on U.S. presidential politics. This study seeks to extend the sociological and psychological concept of hegemonic masculinity to Esquire's feature writing between 1996 and 2016, seeking to determine to what extent, if any, the magazine uses characteristics of the hegemonic masculinity paradigm to frame articles about U.S. presidents and presidential candidates and to what extent, if any, the politician's political party affects the use of such framings.
Structural/functional insights derived from studies of human and zebrafish CFTR orthologs
Authors:   , Zhang Jingyao
Published: September 2024

Cystic fibrosis transmembrane conductance regulator (CFTR) chloride channels play a critical role in regulating the trans-epithelial movement of water and electrolyte in exocrine tissues and the malfunctions of CFTR result in cystic fibrosis, the most prevalent lethal autosomal recessive hereditary disease among the Caucasian populations. Despite decades of biochemical and biophysical studies of CFTR, our understanding of CFTR's structure and gating mechanism remains limited. My dissertation research started with a focus on the structural and functional contribution of the fifth transmembrane segment (TM5) of human CFTR in forming the chloride permeation pathway and continued into tackling the role of the electrostatic profile in the pore for anion flux. These studies have led to the following conclusions: First, TM5 indeed contributes to forming the chloride permeation pathway but TM7 does not line the pore. Unlike the well-studied TM1, TM6, and TM12, the six identified pore-lining residues (A299, R303, N306, S307, F310 and F311) in TM5 only line the internal vestibule of the pore, not the narrow region nor the outer vestibule. Second, changing the side-chain properties of several pore-lining residues along TM5 resulted in channels with two distinct subconductance levels, small conductance O1 state and large conductance O2 state, respectively. Intriguingly, the preferred gating transition C O1 O2 C over C O2 O1 C (namely the O1O2 phenotype) as reported previously for R352 mutations suggests the existence of an irreversible gating process attributed to the input of the free energy from ATP hydrolysis. Then the timely solution of the cryo-EM structures of human and zebrafish CFTR offers a great opportunity to interweave the structural and functional data for a comprehensive understanding of CFTR. Taking a full advantage of this opportunity, I launched a thorough investigation of zebrafish CFTR to fill the blank of functional data for this ortholog. Although current cryo-EM data show minimal structural differences between human and zebrafish CFTR, my electrophysiological characterization of zebrafish CFTR revealed unexpected functional differences, which subsequently offer novel mechanistic insights regarding the mechanism of CFTR gating by ATP binding and hydrolysis.
Imperial masculinities of the modern romance : how intellectuals used imperial rhetoric to reassert middle-class masculinity in late 19th-century Britain
Authors:   , Duncan J. Forrest
Published: September 2024

In this thesis, I argue that authors of the modern romance in late Victorian Britain used imperialism and imperial rhetoric to reassert constructions of British, middle-class masculinity. I do so by examining the life and works of three authors, each with a different relationship and proximity to the British Empire: H. Rider Haggard, H.G. Wells, and Bram Stoker. In doing so, I show that this use of imperialism was not limited to ardent imperialists, such as Haggard, Rudyard Kipling, and Joseph Conrad, but that it could be used by a broader spectrum of middle-class men, including anti-imperialists, like Wells, and imperial collaborators, like Stoker. Each of these authors, despite their vastly different political and social views, wrote stories in which a white, middle-class man was thrust into some unknown territory or wilderness in which he had to engage in conquest of a physical and sexual nature. Through an analysis of each man's non-fiction and fiction works, I demonstrate that these imperial power relations were deeply enmeshed within the very fabric of Victorian life on the domestic front and reveal how they shaped gender, race, and class in this period. Finally, I reveal how such constructions of imperial masculinity persist in the 21st century in both Britain and the United States.

The article classifies various types of internet resources according to the structure of the conversion funnel. It proposes to divide different types of websites into four distinct classes: landing pages, informational or content websites, online stores, and SAAS applications. For each type of website, a system of key performance indicators (KPIs) has been developed, taking into account their individual specificities. For landing pages, it is recommended to use the following KPIs: bounce rate, scroll depth, scroll maps, click maps, and session recordings. For informational web resources, in addition to scroll metrics, a system for measuring the active time a user spends on the web page has been added. Additional software was developed using the Google Tag Manager framework and the JavaScript programming language to ensure tracking of the active time users spend on the page. For online stores, the method of tracking user movement through the conversion funnel is described in detail. This includes steps such as viewing the main page of the online store, viewing products in categories, visiting a specific product page, adding to the wishlist, adding a product to the cart, removing a product from the cart, starting the checkout process, selecting a delivery method, completing the payment process, and the thank you page for successful order placement. Appropriate performance indicators are selected for each of these steps in the conversion funnel. In addition to the key performance indicators for SAAS products, the peculiarities of applying cohort analysis are highlighted, and a system of main performance indicators is developed. Examples of the application of specific performance indicators for solving typical SAAS application analytics tasks are provided. When considering the defined key performance indicators for each type of website, examples of the use of analytical software for creating reports with the necessary metrics are provided. Google Analytics was used as the primary tool for conducting scientific experiments. Hotjar and Microsoft Clarity software were applied to create scroll maps and click maps.

Since 2009, the process of creating virtual financial assets, in particular bitcoin, has been taking place in Ukraine, as in many countries of the world, and the scale of this activity is growing almost exponentially. The lack of state regulation creates the problem of lack of accounting and control of those negative effects on ecology and economy that arise in the process of creating virtual financial assets, i.e. mining. The work analyzes the findings of domestic and foreign scientists regarding the risks inherent in the creation of virtual financial assets, the main of which are the significant consumption of electricity produced from non-renewable sources, carbon and heat emissions, the use of clean water and the creation of electronic waste. Three stages in mining activity are defined and the problems of risk reduction inherent in each stage are defined. The first stage is decisive in terms of preventive actions regarding the risks that will arise in the next stage. At this stage, it is necessary to decide on the location of the equipment, the type of equipment that will be used in the mining process. In our opinion, providing mining with a unique code in KVED and introducing licensing of the specified activity are mandatory actions of the state on the way to reducing the risks associated with the creation of virtual financial assets. Licensing conditions must contain requirements for minimum energy efficiency, setting limits on the use of electricity and Internet traffic, and obligations regarding the safe disposal of electronic waste. At the second stage, it is important to choose the Proof-of-Stake consensus mechanism, which will allow you to save electricity. The third stage involves providing information on the type and amount of resources that were used during mining, as well as on the amount of carbon and heat emissions, during the release of the created assets to the market. This will enable investors to make informed decisions taking into account their attitude to environmental safety. The need for active actions by the state regarding the recognition of mining as a separate type of activity with its inclusion in the KVED and the introduction of licensing with the inclusion of requirements for reducing risks in miners’ activities in the licensing conditions is substantiated.

Authors: Rud Oleksandr
Published: September 2024

The article is dedicated to analyzing theoretical and methodological approaches to forecasting the economic activity of an enterprise in conditions of limited information availability. The author focuses on the importance of choosing adequate forecasting methods that would allow company management to adapt strategic planning to the changing market conditions and internal environment. The article thoroughly analyzes the possibilities and challenges faced by modern enterprises when forecasting economic indicators. In particular, several key aspects that determine the effectiveness of forecasting models are highlighted: the adequacy of method selection, data accuracy, and the integration of external environment variables. The author emphasizes that forecasting not only helps management adapt to current conditions but also forms the basis for developing strategies to minimize risks and capitalize on new opportunities. Particular attention in the results section is given to the comparative analysis of different types of forecasts–operational, short-term, and long-term, and their application depending on the scale, complexity, and informational provision. An analysis of the classification of forecasting methods and models that cover intuitive, statistical, and combined methods is presented. Specifically, the author distinguishes formalized forecasting methods, which are based on mathematical models and aimed at identifying patterns in past data for future forecasting. These include regression models, autoregressive models, and exponential smoothing models, which determine dependencies based on time series. Separately, the importance of applying combined models, which include different approaches and techniques, is noted to ensure maximum objectivity and reliability of forecasts. Such integration can enhance the accuracy of determining future economic trends and better account for potential external and internal changes, as well as optimize decision-making processes. The author also emphasizes the importance of understanding and choosing the directions of forecasting economic activity, which include managerial, financialeconomic, marketing, production, accounting-control, innovative, and investment aspects. Each direction requires different approaches and forecasting methods depending on the specifics of the activity and external conditions.

The purpose of the article is to study and adapt the foreign experience of regulating mechanisms for the development of tourist potential for the formation of a strategy for the post-war recovery of tourist potential, improving the quality of services and the process of serving guests, and attracting more tourists. It was determined that from the standpoint of a systemic approach, the general tourist potential of the country is a set of interconnected and interacting potentials of regions that are used in the country’s tourism activities. The goals of state regulation of tourism activities in various countries of the world are revealed. The main functions of the state regulation of mechanisms for the development of tourism potential are presented. Models of regulation of the mechanisms of tourism potential development at the state level and their main characteristics are highlighted. The experience of the countries of the European Union regarding the use of forms and methods of state regulation of mechanisms for the development of tourism potential has been studied. It was concluded that in order to solve the problems of the development of tourism potential even during the war years, it is necessary to increase: the flow of investments in the fixed capital of means of accommodation for guests; the number of beds in collective accommodation facilities; the number of employees in hotels and travel companies; volume of paid services provided to visitors by travel firms and collective means of accommodation. The regulatory aspects of the mechanism for stimulating investment and entrepreneurial activity, applied in different countries, which can be useful in domestic practice and adapted to the realities of Ukraine, are summarized. In general, foreign experience demonstrates that the regulation of mechanisms for the development of tourism potential can be based on various aspects that are key in the formation of a strategy for the post-war restoration of tourism potential. Further scientific developments have a perspective in the direction of implementing foreign experience in regulating the development of the tourist potential of territories.
