Rebuilding Biodiversity One Stone at a Time
Authors: Gowlland Geoffrey
Published: June 2024

This article presents a reflection on the adaptability of an age-old practice, dry stone walling, to address the loss of biodiversity precipitated by locally changing agricultural practices and a globally changing climate. The ‘Art of dry stone walling, knowledge and techniques’, inscribed in 2018 on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity, involves building walls with locally sourced stones without the use of mortar. On relatively homogeneous agricultural land, walls offer precious surfaces, nooks and crannies, for plants and animals to grow on, nest in or move along from one patch of woods to the next. With a focus on practices in Switzerland, the article explores how a new awareness of the ecological potential of dry stone walls is shaping the craft and the composition of the communities of practice that have developed around them.

Stress and Performance in College Sports: A Comprehensive Examination of the Physical, Social, and Psychological Factors
Authors: Zeshan Khan Muhammad , Manzoor Mehwish , Safdar Luqman Muhammad
Published: June 2024

The study examined the relationship between athletic performance and physical stress (fatigue and illness), social stress (family, teachers, and behaviors), and psychological stress (sleep and emotions), as well as the degree to which each stress affected performance. Self-administered surveys were used in a quantitative manner to evaluate athletes' perceived performance and these stressors. 434 athletes from two districts' government colleges participated in the study. Significant positive relationships between all forms of stress and performance were found via analysis. Subsequent investigation revealed that social stress and psychological stress gradually increased the explained variance when added to the model, with physical stress alone accounting for a sizable amount of the performance variance. Future studies ought to examine the fundamental processes via which stress affects performance and look into these connections in a wider range of sample sizes.

Authors: S. B. Waruwu  , D. Satria  , U. Harahap  , H. Purnomo
Published: June 2024

1.3-bis(p-hydroxyphenyl)urea, also called Algetika, has the potential to be developed as an anti-inflammatory with fewer side effects. The potential for developing this substance as an anti-inflammatory is possible. Assays on RAW 264.7 cell viability, nitric oxide formation, and effects on cytokine gene expression (TNF-α, IL-6), iNOS, COX-2, and COX-2 and NF-kB protein analysis were further investigated. The inflammatory trigger in this study was lipopolysaccharide, while the positive control was dexamethasone. Algetika had the best performance in the cell viability test and had the most significant percentage of live cells at concentrations of 31.5 and 62.5 µg/mL. This compound also substantially inhibited/reduced nitrite accumulation, as shown at concentrations of 31.25 µg/mL (11.07 ± 0.74 µM) and 62.5 µg/mL (8.48 ± 0.37 µM). Cytokine gene expression decreased according to RT-PCR findings from gene expression data compared with control LPS cells, showing a significant difference. Analysis of COX-2 and NF-kB protein expression showed a significant decrease. This compound may be anti-inflammatory by reducing nitric oxide levels and cytokine expression.

Published: June 2024

The article considers modern trends of vocal education in China, which are
in the field of research of Chinese and Russian scientists, as well as the authors’ own
recommendations on the problem of improving vocal teaching methods. The development
of new methods based on the use of traditions of European and Russian vocal schools is
noted as the main trend. Problems include the heterogeneity of the educational process,
the absence of a unified methodological system and the lack of scientific literature on the
methodology of vocal teaching in the People’s Republic of China. The problem of insufficient
development of the theoretical block in vocal training in the country is touched upon. At the

related to the growing popularity of vocal art and pedagogy, as well as the introduction of
new methods of vocal teaching.
On the Question of Emperor Julian’s Education in Athens. Prepodavatel XXI vek
Authors: Denisova I. V.
Published: June 2024

The article deals with the question of educating the emperor Julian II the Apostate in Athens in the middle of the IV century. Various written sources have been analyzed such as pagan and Christian ones, as well as autobiographical data of the emperor himself. On this basis the early biography of the late antique apostate emperor is reconstructed, which was quite rich in intellectual terms. Julian’s life and activities in Athens are shown, and the schools in which he studied, both philosophical and rhetorical, for which Athens was famous, are characterized. Julian’s teachers and fellow students are identified. In addition, the article presents the attitude of Julian himself to his studies in Athens and his contemporaries: both friends and enemies of the pagan emperor. The emperor’s love for this city is explained. In this context, the relationship between Julian and his fellow students (St. Gregory and St. Basil, Celsus) and teachers (Himerius, Proeresius, Libanius) is shown. Conclusions are drawn about the pagan nature of Julian’s trip to Athens, as a result of which he was finally initiated into pagan cults and mysteries
Quebec Provincial Elections in 2018 and 2022 and Their Influence on
the Development of the French Speaking Province
Authors: Komarov A. N.
Published: June 2024

The article aims to analyze the results of the Quebec provincial elections in 2018
and 2022 and show their impact on the development of the French-speaking province. The
author believes that the Quebec elections changed the existing party-political situation
in Quebec and challenged the long-standing ideology of the Parti Québécois related to
the achievement of Quebec sovereignty. In the author’s opinion, the election results were
significant not only for Quebec, but for Canada as a whole. The pan-Canadian authorities
are interested in the calm and progressive development of Quebec. At the same time, the victory of the Coalition for the Future of Quebec has not finally removed from the agenda
the idea of holding a third referendum on the sovereignty of Quebec, as it can be realized if
the Quebec Party returns to power
A SCREEN WORK AS A FORM OF SCIENTIFIC KNOWLEDGE
Authors: Korneev Andrey
Published: June 2024

The author discusses the experience and prospects of the convergence of Humanities, natural sciences and technical knowledge based on visual language. Particular attention is paid to the phenomenon of cinema as the main way of expressing the visual language. The author seeks to identify the philosophical foundations of cinema, the awareness of which can contribute to the formation of film studies as a scientific discipline. With this aim, the author turns to methodological tools that allow to define disciplinary and discursive knowledge. To date, film studies are a few loosely interconnected discourses that relate mainly to the field of aesthetics. Making these discourses into a scientific discipline will contribute to their involvement in convergent processes. This integration may lead to changes in the language of philosophy. We are talking about the widespread use of visual language, which will open up new opportunities for scientific research and raising the status of the Humanities. The features of the visual language are shown on the example of using the iconological method, which is used to interpret paintings.

Securing Systems using SIEM and FIM Tools
Authors: Ms Vaishali Kumar  , Abhishek Yadav  , Shivam Bhorde
Published: June 2024

Today, computer networks are heavily documented security issues, making it impractical to manage them without Security Event Management (SIEM). A SIEM solution sets the controls everywhere, enhances information security, recording data from various devices and applications through agents or networks Protects data by aggregating and aggregating Provides filtering, normalization of redundant information it is proprietary, and they use context to analyze it. The SIEM solution provides threat detection and real-time system activity analysis, alerting operators in the event of an attack. Although there are high-quality SIEM solutions, success cannot be guaranteed. Instead, organizations should focus on a variety of use cases to effectively implement their SIEM solutions. Care must be taken with respect to the integrity of the operating system components. They are controlled to optimize system security. Attackers will always try to manipulate or alter these relevant resources to achieve their goals. System files are common targets for attackers. File integrity monitoring tools are often used to detect any malicious changes to these important files. In this project we developed a comprehensive security solution that combines a Security Information Event Management (SIEM) framework with a File Integrity Monitoring (FIM) tool to optimize the security posture of IT projects. Our SIEM project uses Azure Monitoring Agent to collect data from virtual machine and inject it into the Log Analytics Workspace. The FIM component is implemented by a Python script designed to scan multiple directories and files. The script initially stores the hashes of all monitored files in a baseline file named “baseline.txt” and creates backups of the original files. These backups are periodically updated, with old backups being deleted.

У статті містяться результати дослідження інтегральної антиоксидантної активності (АОА) спиртових та водних екстрактів кореневищ з коренями Echinacea purpurea (L.) Moench, вирощеної на навчально-дослідній ділянці Дрогобицького державного педагогічного університету імені Івана Франка. Визначено вплив різних способів екстрагування на показники АОА, виміряні потенціометричним методом з використанням медіаторної системи. Екстрагування проводили шляхом змішування подрібненої висушеної лікарської сировини з 70% спиртом і витримування протягом 14 днів чи дистильованою водою у співвідношенні 1:10 за різної температури та часу її дії. При 1-му способі приготування водних настоїв використовувалась вода кімнатної температури, при 2-му – гаряча вода (70°С), далі в обидвох випадках суміші нагрівали протягом 15 хв на киплячій водяній бані та 45 хв охолоджували. При 3-му способі лікарську рослинну сировину заливали окропом та настоювали 15 хв. Для отримання відвару лікарську рослинну сировину заливали водою кімнатної температури, настоювали шляхом нагрівання впродовж 30 хв на киплячій водяній бані та 15 хв охолоджували. З’ясовано, що показник АОА спиртових екстрактів кореневищ з коренями ехінацеї у 1,2–4,5 разів перевищив аналогічні показники у водних екстрактах, отриманих різними способами, і становив 1,36±0,09 мг АК/мл. Серед обраних способів водної екстракції найефективнішим виявився спосіб приготування відвару, у якому АОА складала 1,13±0,08 мг АК/мл. Це пояснюється особливістю гістологічної будови та природи хімічних речовин, що синтезуються кореневищами з коренями. Найменші значення АОА (0,30±0,02 мг АК/мл) були зафіксовані у водному екстракті, отриманому 3-м способом, тоді як АОА водних витягів за 1-м способом складала 0,78±0,05 мг АК/мл; 2-м способом – 0,88±0,06 мг АК/мл, що у 1,5 та 1,3 рази відповідно поступаються показникам АОА відвару. Отже, з метою отримання екстракту кореневищ з коренями ехінацеї пурпурової з максимальним значенням АОА доцільно готувати спиртовий витяг сировини.

Інвазійні види в сучасному світі стають дедалі більш актуальним питанням. Їх поширення може мати серйозні наслідки як для аборигенних видів, так і для економіки країни. Одним із таких видів є Heracleum sosnowskyi Manden., який широко поширений на території України. Для успішної боротьби з цією рослиною необхідна комплексна інвентаризація та превентивні заходи для запобігання подальшого її розповсюдження. Це велика за розміром рослина, що продукує значну кількість насіння. Воно поширюється за допомогою різних механізмів, включаючи вітер, транспортні потоки та водні шляхи. Такий розподіл насіння дозволяє рослині колонізувати нові території та збільшувати свою популяцію. У своїй стратегії виживання рослина демонструє властивості типу віолент. Вона активно конкурує з іншими видами рослин, здатна до швидкого росту та ефективно використовує ресурси середовища. Це дозволяє успішно адаптуватися до змін у середовищі та забезпечує виживання навіть у конкурентному середовищі. Цей вид становить потенційну небезпеку для людей і тварин. Сік рослини містить фурокумарини, які, взаємодіючи з ультрафіолетовим випромінюванням, можуть призвести до утворення опіків. Ці опіки можуть спричинити некроз тканин та в критичних випадках призвести до летальних наслідків. У цій статті наведено результати дослідження поширення H. sosnowskyi на території міста Надвірна. Проведене з травня до вересня 2022 року дослідження показало значне розповсюдження цього виду в антропогенних біотопах. Найчастіше рослина зустрічалася біля автомагістральних шляхів та вздовж річки Стримба. Загальна площа, де було виявлено цей вид, становить 12,646 га. Також було проаналізовано локалітети виду та визначено рясність за шкалою О. Друде. Аналіз свідчить про те, що поширення H. sosnowskyi може становити серйозну загрозу для аборигенних екосистем, здоров’я і безпеки місцевого населення та тваринного світу. Результати, отримані в ході дослідження, надають важливу інформацію щодо розподілу та поширення виду, що відкриває можливості для подальшого моніторингу та розробки стратегій контролю та управління.

Authors:   LLC “Ville Forte Ukraine”, Iatsenko Oleksandr
Published: June 2024

In the conditions of martial law, the importance of export of agricultural products is increasing, as Ukraine remains an agrarian country and guarantees the food security of the world. Therefore, the research of various aspects of agribusiness remains relevant. The article used a set of different methods of scientific knowledge, namely logical, descriptive, system-structural and others. An essential-conceptual analysis of the term “logistics” was carried out based on approaches to considering this concept at the macro- and micro-levels. The expediency of using a general approach to the definition of the term “logistics” is substantiated, as it covers a wider range of content. The significant role of innovations, technologies and information flows for improving the quality of logistics systems is noted. The definition of the term “agrologistics” has been formed, which takes into account the specifics of the agro-industrial complex. One of the special characteristics of logistics in agriculture, unlike other industries, is that the efficiency of logistics systems of agribusiness entities depends on the degree of continuity of management, organization and flow control processes and the level of digitization of these processes, as well as on the development of logistics infrastructure. The export of agricultural products by means of transport is outlined, with an analysis of the factors and conditions for choosing sea, rail or road transport. The conditions of international trade according to Incoterms are described. Detailed requirements and rules based on EXW (Ex Works), CPT (Freight/Carriage Paid Before), FCA (Free Carrier), DDU (Delivery Duty Free), DAF (Delivery to Border), FOB (Free on Board) and they are distributed by types of transport. The current state of export of agricultural products by types of transport in Ukraine is assessed, the important role of sea transport in agribusiness is determined. The main tasks facing agro-enterprises to improve the state of agro-logistics and boost exports have been formulated. Transport costs make up the largest share of export costs, therefore, the establishment of agro-logistics policy, the search for new strategies and solutions can give an impetus to the development of agricultural business entities of Ukraine. A conclusion was made about opportunities and threats for the further development of agribusiness in Ukraine.

Published: June 2024

The construction of a classification of tools for managing the portfolio of international business projects of enterprises is important from a theoretical and practical point of view, as it allows systematizing the available tools and methods, ensuring their effective use in various situations. From a theoretical point of view, this classification contributes to the development of a scientific approach to project portfolio management, defining the main categories of tools and their purpose, which helps in a clear understanding of their application and functionality. In the process of analyzing various tools for managing a portfolio of international business projects, it was proven that effective management requires the use of a complex of quantitative and qualitative methods. It is well-founded that quantitative tools such as portfolio analysis, capital investment and budgeting, as well as monitoring and control, ensure the accuracy of measurements and the objectivity of decision-making with the help of numerical data and statistical analysis. On the other hand, it is argued that qualitative methods, such as SWOT analysis, process management, and intercultural communication, provide a deeper understanding of the contextual aspects of projects, allowing to reveal non-obvious opportunities and threats that cannot always be quantified. It is also confirmed that regular tools such as ERP systems and digital communication tools contribute to the continuous optimization of the company’s activities and support daily operations, while ad hoc tools such as portfolio analysis and risk analysis are applied for specific situations , which require special attention or a quick reaction. This indicates the importance of flexibility in the choice of tools depending on the current needs and strategic goals of the enterprise. In general, the success of managing a portfolio of international business projects depends on the balanced use of various management tools that allow for a comprehensive assessment of internal and external factors, as well as an effective response to the dynamic international environment.

Structural and Size Effects on the Spectroscopic and Redox Properties of CdSe Nanocrystals in Solution: The Role of Defect States
Authors: Amelia Matteo , Impellizzeri Stefania , Monaco Simone , Yildiz Ibrahim , Silvi Serena , Raymo Françisco M. , Credi Alberto
Published: June 2024

Two series of CdSe quantum dots (QDs) with different diameters are prepared, according to frequently used protocols of the same synthetic procedure. For each sample the photophysical properties and the potentials for the first reduction and oxidation processes in organic solution are determined. The band gap obtained from electrochemical experiments is compared with that determined from the absorption and luminescence spectra. While the optical band gap decreases upon increasing the nanocrystal diameter, as expected on the basis of quantum confinement, the redox potentials and the electrochemical band gap are not monotonously related to the QD size. For both series, the smallest and largest QDs are both easier to oxidize and reduce than mid-sized QDs. In fact, the latter samples exhibit very broad voltammetric profiles, which suggests that the heterogeneous electron-transfer processes from/to the electrode are kinetically hindered. Conversely, the electrochemical band gap for the smallest and largest particles of each series is somewhat smaller than the optical band gap. These results indicate that, while the optical band gap depends on the actual electron–hole recombination within the nanocrystal, and therefore follows the size dependence expected from the particle-in-a-box model, the electrochemical processes of these QDs are strongly affected by other factors, such as the presence of surface defects. The investigations suggest that the influence of these defects on the potential values is more important for the smallest and largest QDs of each series, as confirmed by the respective luminescence bands and quantum yields. An interpretation for the size-dependent evolution of the surface defects in these nanocrystals is proposed based on the mechanism of their formation and growth.
Photoinduced Enhancement in the Luminescence of Hydrophilic Quantum Dots Coated with Photocleavable Ligands
Authors: Impellizzeri Stefania , McCaughan Bridgeen , Callan John F. , Raymo Françisco M.
Published: June 2024

In search of strategies to photoactivate the luminescence of semiconductor quantum dots, we devised a synthetic approach to attach photocleavable 2-nitrobenzyl groups to CdSe–ZnS core–shell quantum dots coated with hydrophilic polymeric ligands. The emission intensity of the resulting nanostructured constructs increases by more than 60% with the photolysis of the 2-nitrobenzyl appendages. Indeed, the photoinduced separation of the organic chromophores from the inorganic nanoparticles suppresses an electron-transfer pathway from the latter to the former and is mostly responsible for the luminescence enhancement. However, the thiol groups anchoring the polymeric envelope to the ZnS shell also contribute to the photoinduced emission increase. Presumably, their photooxidation eliminates defects on the nanoparticle surface and promotes the radiative deactivation of the excited quantum dots. This effect is fully reversible but its magnitude is only a fraction of the change caused by the photocleavage of the 2-nitrobenzyl groups. In addition, these particular quantum dots can cross the membrane of model cells and their luminescence increases by ∼80% after the intracellular photocleavage of the 2-nitrobenzyl quenchers. Thus, photoswitchable luminescent constructs with biocompatible character can be assembled combining the established photochemistry of the 2-nitrobenzyl photocage with the outstanding photophysical properties of semiconductor quantum dots and the hydrophilic character of appropriate polymeric ligands.

Published: June 2024

This study explores the impact of rewards, work environment, and motivation on the performance of administrative staff at the Faculty of Economics, State University of Malang. This study uses the Explanatory Research method with a sample of 47 employees. Data were collected through questionnaires and analysed using path analysis and SMARTPLS3 as the statistical test. The results confirmed that reward and motivation directly impact staff performance, while the work environment has no direct impact. In addition, the findings suggest that motivation serves as a mediator in the relationship between rewards, work environment, and performance. The importance of providing appropriate rewards and creating conducive working conditions to stimulate motivation has been proven in this study. These results provide a valuable perspective for educational institutions in their efforts to improve the performance of education personnel in enhancing academic services.
De la buena administración y el acceso a la información pública en Colombia

Published: June 2024

La buena administración no está reconocida de forma expresa en el ordenamiento jurídico, pero se deduce rápidamente al realizar una lectura sistemática del ordenamiento jurídico. La buena administración se manifiesta de distintas maneras, entre ellas con el derecho al acceso a la información pública. Para medir el cumplimiento de los sujetos obligados en esta materia, se creó el Índice de transparencia y acceso a la información a cargo de la Procuraduría (ITA). Así las cosas, el objetivo de esta investigación es determinar el alcance que tiene en Colombia el acceso a la información pública como elemento de la buena administración.

Análisis de la justificación de la sentencia c-258 de 2013 desde la teoría de la argumentación jurídica
Authors: Montenegro Sandón Rubén Darío
Published: June 2024

El presente trabajo se desarrolló con el propósito de analizar la sentencia C-258 de 2013 proferida por la Corte Constitucional, a la luz de la teoría de la argumentación y ponderación desarrollada por Robert Alexy y otros autores. Esta decisión de la Corte Constitucional colombiana estableció que aquellas pensiones que habían sido reconocidas bajo el régimen del art. 17 de ley 4 de 1992, con abuso del derecho o fraude a la ley, y que superaran el límite de 25 SMMLV, debían ser reajustadas a este valor. Del análisis abordado, se ha concluido que desde la argumentación práctica otra respuesta judicial era posible, sin que se desconocieron los derechos adquiridos de quienes venían disfrutando de la prestación de vejez con anterioridad a esa decisión o sin que esa otra respuesta posible, afectará principios de carácter constitucional.

El artículo tiene por objetivo presentar el uso de la técnica de análisis cuantitativo regresión logística multinomial para la identificación de los principales factores que inciden en la optimización del relacionamiento entre empresas y comunidades étnicas en escenarios de procesos de licenciamiento social y responsabilidad social empresarial (RSE). A partir del uso de la regresión logística multinomial se explicarán los principales factores que inciden en la optimización de los escenarios de diálogo, reconocimiento y construcción de consensos entre empresas y comunidades étnicas. El caso analizado se refiere a una compañía de inversión, la cual ha debido tramitar una serie de licencias sociales frente a comunidades étnicas a través de la consulta previa en la ciudad de Cartagena de Indias, lo anterior para poder dar inicio a proyectos de intervención en sus territorios. Se obtiene como resultado que el éxito en la gestión del relacionamiento de la empresa con la comunidad se basa en la confianza que logre generar al interior de esta última y en su involucramiento activo en los procesos orientados al desarrollo, fortaleciendo el tejido social a través de la comunicación, el diálogo y la implicación. Dentro de las principales conclusiones se destaca que la regresión logística multinomial es una técnica de análisis de enorme utilidad para analizar el relacionamiento de una empresa con una comunidad étnica en el marco de una consulta previa, así mismo constituye método confiable para la toma de decisiones informadas y responsables en este tipo de escenarios.
