The main problems associated with the impact of military aggression on the work of social enterprises are identified. The relationship between the economic consequences of the COVID-19 epidemic and military aggression has been established. The scale of the crisis in terms of economic, environmental and demographic aspects has been identified. The main stages of the restoration of social entrepreneurship in Ukraine according to time and substantive criteria are highlighted. The main advantages and disadvantages of social entrepreneurship at the present stage in the context of the main prospects for development after its restoration are described. It is said that Ukraine's integration into the EU means not only the full support of partners, but also the fact that the country faces the challenge of rebuilding state institutions and infrastructure development. The authors state that decentralization will help Ukraine to pass the path of successful post-war reconstruction and say that the international reconstruction program should be based on close cooperation with local governments, because social enterprises provide territorial well-being, material values of society in a certain territory. profit while working for communities. In the study, the authors point out that the support of social business by local governments is mostly carried out within the programs to support small and medium-sized businesses in the pre-war period and now. It is noted that in the process of rebuilding social entrepreneurship, cooperation with cloud platforms will help to conduct preliminary analysis of projects and screenings of dubious social entrepreneurship projects, and some of them only attract companies and investors, are the sole owner of investors in funded enterprises. Analysis was performed of state aid and existing programs to support social enterprises during military aggression and in the recovery period. anti-crisis measures to overcome the negative consequences of military aggression are proposed.

Published: May 2022

The article analyzes project management methodologies in information technology (IT), as well as their advantages and disadvantages of use in this area. Project management methodologies are designed to standardize the work of project teams, which helps to make the project in accordance with the requirements of customers. These are different approaches to the organization of the project. Each methodology includes a unique procedure and workflow. Choosing the right methodology for project management is a topical issue, since it is the field of information technology that is actively developing. Understanding the characteristics of different methodologies and comparing them when used to implement information technology projects will allow scientists, practitioners and team members to make the right choice regarding their application, which will lead to the achievement of project goals. The article highlights four methodologies: Waterfall, Agile, Scrum, Kanban, which are used most often in the field of information technology. Their features of the application of project management are described. They are grouped according to the principles of similarity, popularity. For each of them, guidelines are given for choosing the one that is suitable for the management and implementation of projects in the information sphere. The authors of the article, when analyzing project management merologies, identified their main advantages and disadvantages, which are structured in this study. To obtain the results, methods of analysis and structuring of studies were used. Among the IT project management methodologies are: Scrum Agile methods that significantly reduce the risks of project implementation and provide good communication between all project participants. Waterfall is the most effective for projects with specific parameters and goals. Kanban provides the most flexibility and motivation for all involved in a project. Choosing the right methodology is important because it determines how the team will work on the project and which can lead the project to success or failure. And since there is no one-size-fits-all method for all types of IT projects, it is important to spend some time choosing the right project management methodology. This choice should be based primarily on the needs of the project and the team and be made by the project manager.
ASSESSMENT OF THE LEVEL OF TOURIST DEVELOPMENT BY QUALIMETRY METHODS
Authors:   Lviv Polytechnic National University, Lushchyk Mariya
Published: May 2022

Purpose: to develop a methodology for clustering EU countries on key indicators of the level of tourism development, which will allow for an integrated assessment and comparative analysis of the level of tourism development in selected territorial clusters. Methodology: In this study, two methods were used to determine the level of tourism development in the 27 countries of the enlarged European Union − tree (hierarchical) clustering on the principle of «most distant neighbor» and clustering on the method of K-means. The indicators that, in our opinion, most fully characterize the various parameters of tourism development are the number of world arrivals (thousands of people) and the costs of international tourists within the country (million dollars). Results: Cluster analysis by the method of «tree» clustering on the principle of «most distant neighbor» identified 6 typical clusters by level of tourism development. This hypothesis was not confirmed by verification using another qualimetric method of analysis − clustering by the method of K-means. At the same time, the typical composition of clusters obtained as a result of elaboration of two methods was revealed. We can talk about clusters with a particularly high level of tourism development (in different variations, here are France, Spain, Italy), with a high level of development (Germany, traditionally allocated to a separate monocluster, as well as a separate cluster − Austria, Greece, Netherlands, Portugal, Poland), with medium and low level of development (there is either one numerical cluster with 17 countries, or 2 clusters with relatively lower and higher rates). Practical importance: In our opinion, the study of the main trends of segmentation of the regional competitive tourist space (in our case − the enlarged European Union) is relevant because it provides an opportunity to predict and identify causes or impulses to positive or negative dynamics «post-pandemic» tourism policy.

Published: May 2022

The article deals with the research of gastrodiplomacy campaigns as instruments for branding countries at the international level. The image of any country in the modern system of international relations depends not only on political, economic, military resources, but also on its ability to present itself through culture. That is why public or people's diplomacy is becoming more and more important in foreign policy, in which not only professional diplomats but also representatives of public organizations, business circles, science and education, culture and art, mass media, etc. take an active part. It is emphasized that in recent years a new direction of diplomacy has begun to develop – gastrodiplomacy. It has become an instrument of intercultural relations and relies on the resources of national cuisines. It is used at the dinner table to influence the thoughts and moods of politicians and world leaders, as well as ordinary citizens. Over the past two decades, many countries have successfully conducted gastrodiplomacy campaigns to increase their cultural influence abroad. The article analyzes the gastrodiplomacy campaigns of such countries as Thailand, Japan, Malaysia, Peru, South Korea and Taiwan. These countries were among the first to use gastrodiplomacy as a tool for branding their countries at the international level. It has been established that gastrodiplomacy should not be equated with ordinary advertising campaigns to promote various national food products, as its purpose and objectives are much broader. It is aimed at forming a positive brand of the country in the world by promoting national cuisine, stimulating foreign trade and tourism, improving the investment climate, attracting more investors, increasing the competitiveness of the economy.

Published: May 2022

The article examines the role of financial controlling as a component of the financial stability of an enterprise. It is determined that it is controlling that allows you to establish control over the achievement of both strategic and tactical goals of the organization. This is due to the fact that in modern business practice, controlling acts as an effective tool that provides real chances to survive in the competition, so the financial control system is largely the key to the successful functioning and development of an enterprise in the long term. It is argued that the use of the potential of controlling helps the company to respond in a timely manner to market changes, act on it, constantly focusing on the future, determine the future through effective planning with direct and feedback, following high financial results. It is substantiated that the leading goal of financial controlling is the orientation of the management process towards maximizing the profit and cost of the owners' capital while minimizing risk, while maintaining the liquidity, solvency and financial stability of the enterprise. The main role in the system of ensuring the company's monetary stability should be assigned to internal mechanisms of monetary stabilization.

The article reveals and substantiates the theoretical aspects of determining the objectives of the system of monitoring the activities of business structures. It is established that the formation of the system of monitoring the activities of business structures begins with setting goals for monitoring. It is proved that the problematic aspect of building a universal classification of goals of business structures is: differences in business structures by their purpose and subordinate relations within the structure, as well as industry specifics. Consider the business structures that are created in Ukraine, most of them are unique in terms of structural components, industry affiliation and even strategic importance at the level of the national economy. The algorithm of realization of the purposes of system of monitoring of activity of business structure is constructed. It is proposed to take as initial data for the construction of the monitoring system not the content of the set goals (expansion of markets, growth of market value of assets, increase of profit, ensuring financial stability, etc.), but their hierarchy and causality. This approach will make it possible to develop universal recommendations for the formation of a system for monitoring the activities of business structures. The classification of the purposes of business structures is offered and proved. In the proposed classification, the types of goals are interrelated on various grounds, and together constitute a holistic system. Two goal cubes are constructed to facilitate the logic of the connections. The given goals of the business structure in terms of scale and level of coverage are a set of sets that form a boulevard. Within a specific business structure, a process model is presented, which can be detailed and developed in the direction of reflecting the specifics of the objectives of structural components, as well as industry characteristics.

The study of the historical origins of the prosecution in Ukraine is a mandatory component of its study not only as a socio-legal phenomenon of public law, but also as a specific subjective institution endowed with an appropriate array of powers. The activities of the prosecution and its officials have always been included in the permanent process of state formation, so the context of finding the prerequisites for such a body and its development is a structural part of research aimed at researching the current legal status of the prosecution bodies of Ukraine and its formation. At the same time, given the staged development of the prosecution in Ukraine in different historical periods, it should be noted the accumulation of interest of the scientific community in comparative academic research to compare the current process of development of the prosecution bodies within the general changes in Ukraine. Therefore, given this and the continuous process of public law reform, it is not superfluous to trace the nature of structural and functional metamorphoses of the prosecution, as well as their analogues and prototypes, in previous historical times, including from the standpoint of the rule of law. to date. Based on the analysis of the genesis of the historical development of the prosecution in Ukraine of different epochs, research approaches to understanding the concept of the prosecution as such and its functional load in different historical periods, outlined the main stages in the periodization of the history of development, its place and role in historical and state formations, the main model approaches to the organization of activity and functioning of prosecution, interrelation of prosecution bodies in Ukraine and other branches of power in different times from emergence of prototypes of bodies of prosecution bodies to the present are found out.

The article is devoted to the analysis of the institution of the Commissioner for Human Rights (Ombudsman) in the Scandinavian countries - Sweden, Norway and Denmark. In the article the authors research the history of the ombudsman, analyze the current legislation of the Scandinavian countries, which regulates the appointment and dismissal of the Commissioner for Human Rights, the jurisdiction of ombudsmen, the main tools and powers. The authors found that the institution of ombudsman originated in Sweden, where there is currently a strong model of parliamentary ombudsman. The institution of the Parliamentary Commissioner for Human Rights in Sweden consists of four ombudsmen, one of whom is the head and three others in certain specific areas. The parliamentary ombudsman in Sweden has extremely broad powers, including the right to control the authorities and the military; to be present at court hearings; apply disciplinary action or prosecute officials. In addition to parliamentary ombudsmen in Sweden, there are also ombudsmen with powers in certain areas of public life. The Parliamentary Ombudsman in Norway is also an independent official, but he has much narrower powers. Acts of the parliamentary ombudsman are of a recommendatory nature, but are usually implemented by the bodies and persons to whom they are addressed. Its competence extends exclusively to the civil administration (there is a separate military ombudsman), but does not extend in particular to the courts, the activities of the Accounting Chamber and some other authorities. In addition to the Parliamentary Ombudsman, Norway has an Ombudsman for the Rights of the Child (Norway became the first country to introduce such a position), an Ombudsman for the Protection of the Rights of Armed Forces, an Ombudsman for Equality and Non-Discrimination, and local ombudsmen. In addition to his traditional powers, the Danish ombudsman is empowered to monitor existing laws and other administrative regulations. In case of shortcomings, the ombudsman informs the parliament, the responsible minister, local governments. The Ombudsman has the right to receive information, documents, written statements, etc. from the authorities in order to investigate or consider a complaint. However, the Danish ombudsman may not criticize or make recommendations to public authorities or their officials until they can make a statement on the matter. In addition to the parliamentary ombudsman, there are also local ombudsmen in Denmark, including the ombudsman of Greenland and ombudsmen in every major city. The authors concluded that the Swedish model of ombudsman should be implemented in Ukraine.

The relevance of the study reflected in the article is related to the question of the peculiarities of establishing facts of legal significance (legal facts) in civil proceedings. Cases of establishing facts of legal significance today remain an essential part of civil proceedings and a significant category of cases considered in separate proceedings. The issues raised in the article are investigated by acquainting and analyzing the norms of civil law, scientific works, as well as the case law of courts of general jurisdiction in Ukraine. Attention is focused on the purpose of the procedure of establishing facts of legal significance, in particular, the possibility of establishing the latter in court is emphasized only in cases where for the person interested in this, such establishment is important. In particular, the importance of establishing legal facts when accepting an inheritance in order for the heir to obtain a certificate of the right to inheritance is analyzed. The focus is on the purpose of the procedure for establishing facts of legal significance, namely the possibility of establishing in court only in cases where for the person interested in this, such establishment is important. In particular, the importance of establishing legal facts when accepting an inheritance in order for the heir to obtain a certificate of the right to inheritance is analyzed. Legal facts are an important category of civil proceedings, and therefore remain today the subject of scientific analysis of many scientists in Ukraine. However, despite the fact that today the issues that are unexplored or understudied in the theory of facts of legal significance have decreased significantly in scope, some issues in this area remain without proper coverage in scientific papers. This determines the relevance of the issue raised by the authors and is of scientific interest in the study of establishing the facts that have legal means, and therefore require in-depth scientific analysis with further generalization and formulation of proposals. The authors investigate the significance of facts that have legal significance in terms of legal relations of discovery and acceptance of inheritance. In particular, the cases when certain elements for the discovery of heritage are unknown are investigated. The proposed proposal is proposed to identify facts that have legal significance as those provided by the Civil Procedure Code of Ukraine, and not directly defined in the legislation of Ukraine, but meet the general principles of civil law, indicating or not which rules of law link termination of certain legal consequences, in particular, the emergence of rights and obligations.

The article is devoted to the analysis of the case law of the European Court of Human Rights in the field of family law. In this article, the authors explore the definition of "family life" in the case law of the European Court of Human Rights; topical issues on the recognition of cohabitation of same- sex couples in family life and on the state registration of same-sex marriages; issues of protection of the child's interests in resolving family law disputes. The authors point out that the case law of the European Court of Human Rights is a source of family law in Ukraine. The authors found that the European Court of Human Rights uses an autonomous concept of "family life", which is broader than the definition of "family" and is characterized by certain criteria. In matters of same-sex marriage, the European Court of Human Rights recognizes same-sex partnerships in family life, but leaves it to the state to register such marriages. In the judgments analyzed by the authors, the European Court of Human Rights assumes that Article 12 of the Convention for the Protection of Human Rights and Fundamental Freedoms enshrines the traditional model of marriage. The authors conclude that the issue of legalization of same-sex marriages should be decided by states taking into account ethnic, cultural, religious and other characteristics. In matters relating to the protection of the rights of the child, the European Court of Human Rights uses the notion of "the best interests of the child". The Court emphasizes the special bond between children and their biological parents, which is part of family life.The state must ensure the child's right to communicate with other relatives and persons with whom the relationship is important to the child, as well as the child's right to develop in a safe, secure and stable environment. Parents should have equal rights in resolving child custody disputes. When deciding on paternity, DNA analysis is the only scientific method of accurately establishing the paternity of a particular child and its probative value significantly exceeds any other evidence presented by the parties to confirm or deny their close relationship.

The article is devoted to topical issues of tourism development. Some aspects and specific characteristics of tourism development are considered. The analysis allowed to determine possible directions of development of tourist activity by the formation of unique tourist offers based on the analysis of tourist potential of a tourist destination. The key trends in the development of tourism in the world are highlighted. Today, tourism is one of the important areas of the economy in many countries around the world. The industry's contribution to world GDP in 2019 was 10.4%, in 2020 due to the coronavirus pandemic it decreased to 5.5%. Therefore, it is necessary to develop new management models and tourism development programs to return the industry to its position in 2019, as well as to improve them in the future. In particular, some trends in the development of tourism in different countries were analyzed, which allowed making a comprehensive description of trends in the tourism market. An important component of the development of tourism is the formation of its own attractive tourist image. The image of the destination is of fundamental importance in attracting investors and consumers of tourism products. At the level of tourism marketing in the country, the creation of its favorable image becomes a state task, the solution of which largely determines the success of the tourist complex. Based on the analysis of trends in the tourism market, elements of marketing promotion that are characteristic of developing tourist destinations were identified. Among such tourist destinations was Albania - a tourist destination was described as a destination that was not in high demand due to outdated material and technical base and geopolitical situation in the country, one of the few traditional Muslim countries in Europe, attracting tourists with unique nature and rich nature a combination of recreational beach tourism and cultural and historical monuments that accompany the tourist at every turn. The analysis of the tourist potential of the country allowed to determine the features of tourist activity in the country. Based on the analysis, the article highlights the main mechanisms for the development of tourism, in particular: branding of tourism; creating a positive image of tourist destinations; increasing the environmental friendliness of tourism activities; promoting the recovery of demand for tourist destinations.

Plus spécifiquement, nous analysons comment ces dynamiques contribuent au déploiement d’un nouveau mode d’objectivation social. Il s’agit, d’une part, de montrer comment ce mode d’objectivation repose sur l’intégration des médias socionumériques au sein de circuits marchands. D’autre part, nous éclairons comment le processus d’industrialisation du traitement des données personnelles induit de nouvelles modalités de régulation sociale fondée sur des procédés algorithmiques. Nous présentons enfin comment se traduit cette « gouvernementalité algorithmique » sur le plan des représentations symboliques constitutives de l’« objectivité » que prennent les rapports sociaux et de la signification que les sujets accordent à leurs pratiques.
Suppressing the excitonic effect in covalent organic frameworks for metal-free hydrogen generation
Authors: Yu Hongde , Wang Dong
Published: May 2022

Photocatalytic hydrogen generation is a promising solution for renewable energy production and plays a role in achieving carbon neutrality. Covalent organic frameworks (COFs) with highly designable backbones and inherent pores have emerged as novel pho-tocatalysts, yet the strong excitonic effect in COFs can impede the promotion of energy conversion efficiency. Here we propose a facile approach to suppress the excitonic effect in COFs, which is by narrowing the bandgap and increasing the dielectric screening via rational backbone design and chemical modifications. Based on the GW-BSE method, we uncover a linear relationship be-tween the electronic dielectric constant and the inverse square of the optical bandgap of COFs of Lieb lattice. We further demon-strate that both reduced exciton binding energy and enhanced sunlight absorption can be simultaneously realized in COFs with narrow bandgap. Specifically, we show that one of our designed COFs whose exciton binding energy is nearly half that of g-C3N4 is capable of metal-free hydrogen production under near-infrared light irradiation. Our results showcase an effective method to suppress the excitonic effect in COFs, and also pave the way for their applications in photocatalytic, photovoltaic, and other related solar energy conversions.

Published: May 2022

The discovery of new organometallic frameworks is of high interest for the field of bioorganometallic chemistry. In this work, to the best of our knowledge, we report the first synthesis of various N-metallocenyl ynamides and some of their reactivity. In particular, the use of hypervalent iodine(III) reagents triggered an unprecedented oxidative cyclization leading to ansa[3]-ferrocenyl compounds while the same reaction conditions with the ruthenocene analogues led to an acyclic acetoxy-adduct. The mechanism of the cyclization has been studied by means of DFT calculations, showing that it proceeds through a Concerted Iodination Deprotonation (CID) step. This study not only expands further the chemistry of ynamides but also opens up new avenues in bioorganometallic chemistry by providing an exclusive access to an original ferrocephane moiety to be employed in this research field.
Iron-mediated peptide formation in water and liquid sulfur dioxide under early Earth conditions
Authors: Sydow Constanze , Sauer Fabian , Siegle Alexander F. , Trapp Oliver
Published: May 2022

Peptides have essential structural and catalytic functions in living organisms. The formation of peptides requires the overcoming of thermodynamic and kinetic barriers. In recent years, various formation scenarios that may have occurred during the origin of life have been investigated, including iron(III)-catalyzed condensations. However, iron(III) catalysts require harsh conditions and the catalytic activity in peptide bond forming reactions is low. It is likely that in an anoxic environment such as that of the early Earth, reduced iron compounds were abundant, both on the Earth's surface itself and as a major component of iron meteorites. Here we show, that reduced iron activated by acetic acid mediates efficiently peptide formation. We observed, both in water and liquid sulfur dioxide, up to four amino acid/ peptide coupling steps and the formation of up to decamers. In 21 days 4.1% triglycine G3 and 11.3% tetraglycine G4 were formed. Addition of G3 and dialanine A2 yielded 26.0% G4. Therefore, this is a highly efficient and plausible route for the formation of the first peptides as simple catalysts for further transformations in such environments.

Published: May 2022

Paper offers a low-cost and widely available substrate for electronics. It posses alternative characteristics to silicon, as it shows low density and high-flexibility, together with biodegradability. Solution processable materials, such as hybrid perovskites, also present light and flexible features, together with a huge tunability of the material composition with varying optical properties. In this study, we combine paper substrates with halide-mixed perovskites for the creation of low-cost and easy-to-fabricate perovskite-on-paper photodetectors with a broadband-tunable spectral response. From the bandgap tunability of halide-mixed perovskites we create photodetectors with a cut-off spectral onset that ranges from the NIR to the green, by increasing the bromide content on MAPb(I1-xBrx)3 perovskite alloys. The devices show a fast and efficient response. The best performances are observed for the pure I and Br perovskite compositions, with a maximum responsivity of 376 mA/W on the MAPbBr3 device. This study provides an example of the wide range of possibilities that the combination of solution processable materials with paper substrates offer for the development of low-cost, biodegradable and easy-to-fabricate devices.
Synthesis of Thiomorpholine via a Telescoped Photochemical Thiol-ene/Cyclization Sequence in Continuous Flow
Authors: Steiner Alexander , Nelson Ryan C. , Dallinger Doris , Kappe C. Oliver
Published: May 2022

A procedure for the continuous flow generation of thiomorpholine in a two-step telescoped format was developed. The key step was the photochemical thiol-ene reaction of cysteamine hydrochloride and vinyl chloride as low-cost starting materials under highly con-centrated (4 M) conditions, leading to the corresponding half-mustard intermediate in quantitative yield. Thiomorpholine was subsequently obtained by a base-mediated cyclization. The robust-ness of the process was demonstrated by performing the reaction for 7 h (40 min overall residence time) isolating the desired thio-morpholine via distillation.

A aprendizagem em geometria, a partir da Teoria dos Registros de Representação Semiótica (TRRS), perpassa pela condução e pelo desenvolvimento de uma forma de olhar própria, que envolve, entre outros, três elementos cognitivos, os quais daremos destaque no artigo, a saber: os olhares, as apreensões e a desconstrução dimensional. Nosso objetivo, neste trabalho, é apresentar a análise de uma coleção de livros didáticos de matemática, destinados aos anos iniciais do Ensino Fundamental, no tocante ao uso de malhas geométricas, no ensino e aprendizagem de figuras planas e espaciais, focando nos três elementos da aprendizagem em geometria citados anteriormente. É uma investigação de abordagem qualitativa, em que buscamos identificar o que o uso dessas malhas, presentes em atividades da coleção analisada, nos diz sobre os três elementos cognitivos destacados como importantes para a aprendizagem em geometria na TRRS. Destacamos, como resultado da análise realizada, que a coleção em questão explora dois tipos de malhas nas atividades, a triangular e a quadriculada, dando grande destaque à última, porém, sendo interessante a articulação dos olhares e das apreensões apresentadas. No entanto, indicamos que os olhares avançam do icônico ao não icônico construtor, porém, o olhar inventor ainda precisa ser melhor explorado, pois é o olhar que mais favorece a desconstrução dimensional no trabalho com figuras em geometria. Também em relação à desconstrução dimensional, observamos que ela é explorada normalmente mudando apenas um nível da dimensão, o que é negativo frente a formação do olhar próprio para o trabalho em geometria.

Система підготовки борця на всіх етапах багаторічного удосконалення зумовлена сукупністю завдань індивідуалізації підготовки спортсмена з урахуванням ґендерних особливостей, віку, функціонального стану, змістом тренувального процесу, особливостями змагальної діяльності для досягнення високих спортивних результатів. Мета – визначити особливості функціональної підготовленості борців греко-римського стилю на етапі попередньої базової підготовки у підготовчому періоді. Методи дослідження. Були використані теоретичні методи дослідження (теоретичний аналіз наукової та методичної літератури) та емпіричні: дослідження анаеробної працездатності за Вінгейт-тестом та фізичної працездатності – за тестом PWC170, а також методи математичної статистики. Результати. Значення абсолютної пікової потужності у досліджуваних борців греко-римського стилю на початку підготовчого періоду становило 466,78 ± 11,78 Вт, відносної пікової потужності – 10,64±0,25 Вт/кг, абсолютної середньої потужності – 349,02 ± 9,00 Вт, відносної середньої потужності – 7,96±0,20 Вт/кг, мінімальної потужності – 231,26 ± 8,57 Вт, відносної мінімальної потужності – 5,28 ± 0,19 Вт/кг. Звертає на себе увагу підвищений коефіцієнт стомлення, який перевищував нормативні значення для борців та був на рівні 50,22 ± 1,57%, що зумовлює необхідність включення засобів для збільшення адаптивних можливостей організму та поліпшення відновлювальних процесів. Результати тестування показників фізичної працездатності борців на початку дослідження показали дані, нижчі за середні, характерні для цього виду спорту абсолютні та відносні значення. Абсолютні значення aPWC170 і вPWC170 становили в досліджуваній групі борців 559,08 ± 9,85 кгм/хв і 12,79 ± 0,26 кгм/хв/кг, що відповідало рівню, нижчому за середній. Середньому рівню відповідала також величина вМПК – 52,58 ± 0,67 мл/хв/кг. Висновки. Знижені показники анаеробної та аеробної працездатності є важливими передумовами розробки програми удосконалення функціональної підготовленості борців греко-римського стилю на етапі попередньої базової підготовки у підготовчому періоді.
ЗАСТОСУВАННЯ УКОЛІВ ПІДВИЩЕНОЇ СКЛАДНОСТІ У СУЧАСНОМУ ПАРАОЛІМПІЙСЬКОМУ ФЕХТУВАННІ НА РАПІРАХ

У статті описано змагальну діяльність фехтувальників-рапіристів в параолімпійському спорті, де визначали застосування уколів підвищеної складності. Систематизовано дані літератури відносно техніко-тактичних дій фехтувальників-рапіристів на візках. Предметом дослідження є застосування уколів підвищеної складності в змагальній діяльності фехтувальників-рапіристів на візках. Мета дослідження – аналіз результативності ведення бою фехтувальників-рапіристів високої кваліфікації у сучасному параолімпійському фехтуванні на рапірах уколами підвищеної складності. Матеріали і методи. У педагогічному дослідженні взяли участь 28 фехтувальників-рапіристів на візках високої кваліфікації (жінок-рапіристів – 12 осіб), (чоловіків-рапіристів – 16 осіб). Експертами було проаналізовано 58 поєдинків протягом 2021 року на Чемпіонаті світу та Етапі Кубка Світу в Польщі та Паралімпійських Іграх у Токіо. Результати роботи. Для ефективного завершення змагального поєдинку параолімпійців на візках повинно знаходитись на високому рівні швидкість, точність і реакція, бути напористим при виконанні техніко-тактичних дій, ефективність яких залежить від здібностей фехтувальника-рапіриста оцінювати ситуацію, яка виникла в ході виконання рухів, і вносити при виконанні прийомів необхідні зміни для досягнення запланованого і максимального результату. Тому спортсмен повинен виконувати не тільки атакуючи дії, але і за мінімальний час оцінити ситуацію і прийняти єдине правильне рішення. Висновки. Отримано результати педагогічного спостереження висококваліфікованих фехтувальників-рапіристів на візках, де найвищий показник в змагальній діяльності з уколами підвищеної складності як у чоловіків-рапіристів, так і жінок-рапіристів, найвищий у захисно-відповідних діях – 75,4% і, відповідно, 81,5%. Решта показників за результативністю були дещо нижчими у чоловіків-рапіристів в атаках – 65,2%, ремізи – 58%, і найнижчий показник в контратаках – 44,1%. У жінок-рапіристів була такаж тенденція, де за результативністю в атаках – 57,8%, ремізи – 55,1%, і найнижчий показник в контратаках– 40,5%.
Is the Aotearoa New Zealand Policy Process: fit for purpose?
Authors: Mazey Sonia , Richardson Jeremy
Published: May 2022

New Zealand is generally thought to be well governed by international standards, with low levels of corruption, innovative policies in some sectors, and high levels of trust in the system of government. But all is not well in the public policymaking system. Rather, the system resembles an endless conveyor belt of unsolved, or partially solved, policy problems that have a tendency over time to become bigger ‘crises’. Effective public policymaking is hard and policy ‘stuff-ups’ happen worldwide. But New Zealanders should not accept policy failures as a fact of life. Our central thesis is that, via a series of reforms, the policymaking process could become much more effective in achieving successful policy outcomes.

We explored the risk factors associated with SARS-CoV-2 reinfections in Italy between August 2021 and March 2022. Regardless of the prevalent virus variant, being unvaccinated was the most relevant risk factor for reinfection. The risk of reinfection increased almost 18-fold following emergence of the Omicron variant compared with Delta. A severe first SARS-CoV-2 infection and age over 60 years were significant risk factors for severe reinfection.

Published: May 2022

In this paper, the concept of interval-valued intuitionistic fuzzy sets to subalgebras and ideals of Hilbert algebras is introduced. The inverse image of interval-valued intuitionistic fuzzy subalgebras and interval-valued intuitionistic fuzzy ideals of Hilbert algebras is studied and some related properties are investigated. Equivalence relations on interval-valued intuitionistic fuzzy ideals are discussed.
