Narcisismo evidenciado en Redes Sociales en Estudiantes de Posgraduación del Área de Negocios de Brasil
Authors: Toro Pavel Elias Zepeda , Costa Flaviano
Published: September 2024

Esta investigación tuvo como objetivo verificar la intensidad de narcisismo evidenciado en redes sociales de los estudiantes brasileños de posgraduación stricto sensu del área de negocios. Para lo cual se utilizó un Cuestionario de Percepciones sobre la Intensidad de Narcisismo Virtual. La muestra fue de 605 alumnos de posgraduación stricto sensu del área de negocios de diferentes universidades de Brasil. Los datos fueron analizados a través de Análisis Factorial Exploratorio (AFE). Entre los resultados encontrados, alumnos de maestría  presentan mayor intensidad de narcisismo virtual, en relación a los mismos elementos medidos de los alumnos de doctorado. AFE reflejó 3 grupos para alumnos de maestría  y 4 grupos para alumnos que cursan doctorado. Fueron catalogados según sus características en común, y fueron denominados como: “Autopromoción”; “Egocentrismo”; “Presunción” y “Autoconfianza”. Se cree que una de las principales contribuciones de este estudio es la creación de un cuestionario para capturar Percepciones sobre la Intensidad de Narcisismo Virtual que se inspiró en el modelo de Raskin y Terry (1988). Por su parte, el número de respondientes que se adhirió a la investigación fue significativo, lo que demuestra el interés de las personas en la temática abordada. Así, el estudio innova porque expande una temática de relevancia en el ámbito académico, una vez que la mayor parte de los estudios conductuales son sobre narcisismo en su forma convencional y no consideran aspectos contemporáneos introducidos por las nuevas tecnologías de comunicación virtual.

Higher order class of finite difference method for time-fractional Liouville-Caputo and space-Riesz fractional diffusion equation
Authors: Irandoust-Pakchina Safar , Abdi-Mazraeha Somaiyeh , Fahimi-Khalilabada Iraj
Published: September 2024

In this paper, a class of finite difference method (FDM) is designed for
solving the timefractional Liouville-Caputo and space-Riesz fractional
diffusion equation. For this purpose, the fractional linear barycentric
rational interpolation method (FLBRI) is adopted to discretize the
Liouville-Caputo derivative in the time direction as well as the second
order revised fractional backward difference formulae 2 (RFBDF2) is employed
in the space direction. The energy method is used to prove unconditionally
stability and convergence analysis of the proposed method. Eventually, it is
concluded that the proposed method is convergent with the order O(h? t + h2x
), where ht and hx are the temporal and the spatial step sizes respectively,
and 1 ? ? ? 7 is the order of accuracy in the time direction. Finally, the
presented numerical experiment confirms the theoretical analysis, the high
accuracy and efficiency of the offered method.

Authors: Tunc Tuncay , Erdem Alper
Published: September 2024

In this study, we investigate the Korovkin-type theorems depending upon some
type of convergence such as alpha convergence, semi-alpha convergence and
the notion of exhaustiveness. Since it is known that the convergence types
mentioned above are between point-wise convergence and uniform convergence,
it will be observed that the conditions can be alleviated in the Korovkin
theorem.

Criminal law protection of private life in the context of negative and positive obligations of the state
Authors: Stomatov E.
Published: September 2024

The article examines the significance of the State of Ukraine’s fulfillment of the negative and positive obligation to ensure proper realization, non-interference and protection of the right to privacy for its criminal law protection. The author emphasizes the importance for each State which is a party to the European Convention on Human Rights to formulate a national criminal law policy around criminalization of socially dangerous encroachments on human privacy in the context of compliance with the provisions of Article 8 of the European Convention. The author reveals the concept and content of the negative and positive obligations of the State in this area. The author analyzes the doctrinal approaches to understanding the significance of the ECHR legal positions formed because of legal interpretation of the provisions of the European Convention as a source of criminal law and criminal law policy of Ukraine. The author develops the position that such legal positions are not a source of criminal law. The author concludes that the provisions of the Convention on ensuring respect for human privacy, as interpreted by the ECtHR in its judgments (whether in respect of Ukraine or any other State party to the Convention), may be recognized as grounds for criminalization in a narrow sense, which does not include penalization. Formation of two main approaches to understanding the “right to respect for private life” provided for in Art. 8, namely, as the state’s obligation not to interfere in the private sphere of a person (negative obligation) and as the state’s obligation to take active steps to protect this right (positive obligation), actually combines the right to non-interference by the state in the private life of a person and the right to respect, which is realized through the creation of effective mechanisms for the protection of the right to privacy by both state bodies and individuals. Thus, the need to fulfill the negative and positive obligations of the State to comply with Article 8 of the European Convention is a significant factor in the social conditionality of criminal law protection of respect for private and family life in the context.
Terms of consideration of claims in disciplinary proceedings through the prism of individual decisions of the Higher Qualification and Disciplinary Bar Commission
Authors: Vovniuk V.
Published: September 2024

The article analyzes some aspects of consideration of claims (complaints) for improper behavior of an advocate, which may result in his disciplinary responsibility, in terms of compliance with the terms of consideration of such claims (complaints) provided for by the current legislation.
To date, the legislation provides for any person to file a complaint against an advocate regarding the disciplinary action of the latter. This opportunity is primarily intended to protect people’s rights from unlawful and illegal actions of an advocate. The protection of rights includes, among other things, the inevitable onset of specific disciplinary responsibility of the advocate.
The author analyzed the decisions made by the Higher Qualification and Disciplinary Bar Commission based on the results of the review of the decisions of the Qualification and Disciplinary Bar Commissions regarding compliance with the terms of disciplinary proceedings in the process of considering claims (complaints) regarding the behavior of advocates. Through the prism of the decisions of the HQDBC, the approximate terms of the disciplinary proceedings have been established, within which claims (complaints) are considered.
This study took into account the decisions of the HQDBC, made by this self-governing body of the bar in 2023. These decisions related to the QDBC’s inaction regarding failure to make timely decisions based on the results of the claim (complaint) submitted to advocates, groundless suspension of disciplinary proceedings against the advocates, long-term inaction of the QDBC regarding failure to take any actions to consider the claim (complaint).
The analysis of these decisions made it possible to distinguish problems that directly affect the legality of the final decision of the QDBC. At the same time, such an analysis made it possible to assess the systemic nature of this problem and determine its causes.
According to the results of the study of the Law of Ukraine “On the Bar and Practice of Law” [1], the author concluded that there is no article in it that would provide for the responsibility of persons participating in the decision-making of the QDBC, which contributes to the violation of the principle of reasonable time of the hearing. In turn, the analysis of the practice of the decisions of the HQDBC provided an opportunity to confirm the fact that the terms of consideration of cases are too long, exceed the limits of both reasonable time of the hearing and the terms specified in sub-legal normative acts, and often lead advocates to avoid responsibility.
The objective side of the criminally punishable violation of legislation on plant protection
Authors: Kamensky D. V. , Dudorov O. O.
Published: September 2024

The article is devoted to the study of the elements of the objective side of the composition of a criminal misdemeanor, provided for in Art. 247 of the Criminal Code of Ukraine “Violation of legislation on plant protection”.
The foreign experience of criminal protection of flora is partially highlighted. It has been established that within the framework of several criminal law prohibitions, in which damage to objects of plant life appears as one of the alternative consequences of encroachment on various spheres (elements) of the environment, the Criminal Code of the Federal Republic of Germany embodies a different from Art. 247 of the Criminal Code of Ukraine approach toward an end-to-end regime for the protection of plant life, which is a manifestation of law-making authenticity. It has been established that a similar approach was reflected in the project of the new Criminal Code of Ukraine.
The content of the blanket disposition of Art. 247 of the Criminal Code of Ukraine is detailed; acts of regulatory legislation are listed, on which the law enforcement officer must rely when incriminating this criminal law prohibition; actions that can be regarded as a corresponding socially dangerous action
– violation of the legislation on plant protection are specified. Based on the results of the analysis of the text of the criminal law and the limited practice of the corresponding law enforcement, both the justification of the construction of the disposition of the researched prohibition according to the blanket type, and the generally practical problem absence of its proper specification in the way of referring to a number of acts of regulatory legislation have been proven.
Considerations regarding the content of severe consequences as an element of the objective side of the composition of the analyzed criminal offense against the environment have been expressed. The expediency of the existing legislative approach has been pointed out, according to which the delimitation of the composition of the criminal offense provided for in Art. 247 of the Criminal Code of Ukraine, from the composition of related administrative offenses has been carried out on the grounds of socially dangerous consequences.
It has been established that Art. 247 of the Criminal Code of Ukraine remains among the “dead” prohibitions, the reasons for which must be clarified by criminological science. The opinion has been expressed that the problem of the inevitability of the criminal law response to the most dangerous violations of the legislation on plant protection lies not in the legislative, but in the law-enforcement sphere.
System of legal regulation of international air transportation
Authors: Nazarenko Y. L.
Published: September 2024

The Warsaw Convention of 1929 for the unification of certain rules of international air transport is the basis of the legal regulation of international air transport. Agreements supplementing the Warsaw Convention: Hague Protocol of 1955, Guatemala Protocol of 1971 amending the Warsaw Convention, Guadalajara Convention of 1961, Montreal Protocol for the Unification of Certain Rules Relating to International Carriage by Air (1975). The Montreal Interim Airline Agreement of 1966, the Montreal Agreement of 1999. The set of norms of these agreements as a whole constitutes the Warsaw System of Regulation of International Air Transport. IATA – a special non-governmental organization, an association of airlines of ICAO member states – is responsible for determining the specific conditions of international air transportation.
On May 28, 1999, a significant event took place in the field of international private air law: as a result of the three-week work of the Diplomatic Conference on Air Law held at the ICAO headquarters with the participation of representatives of 121 states and 11 international aviation organizations, the Convention for the Unification of Certain Rules of International Aviation Law was adopted of air transportation (Montreal Convention of 1999), which defines the basic legal conditions of international air transportation in the 21st century.
Scientific and technical progress, the rapid development of international air transport, the increase in the safety of its operation made it necessary to expand the scope and more clearly regulate the responsibility of the carrier. This international Convention is designed to provide firm legal guarantees and an adequate level of compensation to persons injured as a result of aviation events, to create a uniform and clear legal regime of responsibility of air carriers for failure to preserve cargo, baggage and delay during their transportation on international lines.
On November 4, 2003, the Montreal Convention entered into force. Among the participants of the Convention are such countries as the USA, Japan, Canada, China, the countries of the European Union, including Ukraine.
The article examines the early development of the aviation industry and the role of the Warsaw Convention in the construction of rules and mechanisms aimed at protecting the interests of both the carrier and the passenger or cargo owner. The development of the norms of the Warsaw Convention in various protocols is revealed. Such as the Hague Protocol (1955), the Guadalajara Convention (1961), the Guatemala City Protocol (1971) and the Montreal Four Protocols (1975), which significantly modernized the provisions on air transport regulations, as seen in the Montreal Convention (1999).

Authors: Dibihantoro Fino Rihab , Suasih Ni Nyoman Reni
Published: September 2024

The importance of access to credit for micro, small, and household craft enterprises, including cooperatives, has become a major focus in improving working capital financing and capital accumulation to support industrial income. The government through the LPDB (Revolving Fund Management Institution) has launched a revolving fund program that aims to strengthen the capital base of cooperatives, increase the capacity of human resources in business and financial management, and increase the role of cooperatives in expanding employment opportunities and reducing poverty. According to data from the Cooperative Business Development Division of the Denpasar City MSME Cooperative Office, from 2021 to 2023, there were five cooperatives that received the LPDB revolving fund program, but did not consistently reapply for the funds. This raises concerns regarding the sustainability of the program and the factors that influence it. This study aims to identify the factors that influence the sustainability of the LPDB program for cooperatives in Denpasar City. Using the MICMAC (Matrix of Cross Impact Multiplications Applied to a Classification) analysis method, this study reveals that the revolving fund administration requirements and members' information and knowledge about the revolving fund have the most significant direct influence. These findings underscore the importance of simplifying the administrative process and improving member knowledge to ensure the success of the program. In addition, active member participation emerged as an important predictor of program sustainability, highlighting the importance of members' direct involvement in supporting their economic activities. Thus using this method can uncover critical factors, and provide a comprehensive understanding that can inform policy adjustments and strategic implementation to improve program sustainability.

Authors: Alcalá-Albert Gregorio Jesús , Guerrero-Martín Jorge , Macías-Montero Raquel , Leñero-Cirujano Miriam , Araujo-Blesa Marta
Published: September 2024

Background: In an increasingly globalized world, public health is a challenge in the future of health systems. Nursing is a fundamental profession in health systems and the purpose of the study is to quantify the scientific production in global public health carried out by nursing to demonstrate its competence, capacity and specialization in this subject. Methods: A bibliometric study was carried out to understand the scientific production of public health nursing in WoS. A total of 17,545 documents were analyzed using Bibliometrix software in version 4.0.5. Results: A notable increase in production is observed over time, a sign of specialization and capacity. The theme focuses on three stages: hygiene and sanitation, infectious diseases and quality, prevention and non-communicable diseases coinciding with the real social needs of each moment. Most of the production is in English and produced by countries with developed economies. Nursing is aligned with current public health needs. Conclusions: Bibliometrics is a good method to quantify scientific production. The results show extensive scientific production in public health nursing, which translates into extensive knowledge of public health by nursing. There is a growth in production in accordance with time as well as an adaptation to the most current themes in accordance with population needs. Public health is an area of concern to countries and nursing can actively participate in studies, planning and leadership of health systems. Public health nursing should not be considered relegated to medicine but independent and of crucial importance to the “Onehealth” concept. Public, private and educational administrations must promote and support nursing research in public health, and it is not advisable to reduce the teaching load of global public health in nursing studies, in favor of the family and community environment.

Plea Bargaining as a Reform in Criminal Procedure Law: An Analysis of Article 199 of the Draft Criminal Procedure Code
Authors: Husin Nabilla Callosa , Husin Naylla Shabilla Callistha
Published: September 2024

The criminal justice process in Indonesia is characterized by lengthy proceedings, significant costs, and a growing prison population, highlighting the need for new policies to address these challenges. The adoption of the plea-bargaining concept, prevalent in common law jurisdictions, offers a potential solution for the Indonesian criminal justice system. Article 199 of the Draft Law on Criminal Procedure introduces a similar concept, allowing defendants who admit guilt to crimes punishable by no more than seven years in prison to have their cases transferred to a shorter trial process. This normative juridical research employed both statutory and conceptual analyses to evaluate the relevance of plea bargaining in the Indonesian context. It aims to assess whether the plea bargaining provisions in Article 199 of the Draft Criminal Procedure Code align with the principles of simplicity, speed, and cost-effectiveness, and whether they conform to Pancasila, the foundational ideology of Indonesia.

The “elektron” Collection of Communication Engineering and Precision Technology
Authors: Mauersberger Klaus
Published: September 2024

The traditional division of electrical engineering into strong and weak current engineering is no longer common today, following a pronounced differentiation in the discipline. For historical purposes, however, the collections need to be traced back to the way they originated so that they can be categorized. This explains why two collections − housed, significantly, in the archetypal home of weak current technology, the Barkhausen Building − are presently exhibited according to their original connection to the subjects of weak current technology and precision engineering. These are the Acoustic-Phonetic Collection and the “elektron” Collections. The latter most closely reflects the divergent paths taken during the development of weak-current technology and precision engineering. As a consequence, it was created from different historical sources and its structure is that of a teaching collection containing museum objects.

Authors: Вараксин А.Н. , Расина Л.Н.
Published: September 2024

С целью систематизации и обобщения статистических моделей, применяемых для оценки радиационного воздействия на биологические системы, проведен анализ математических методов, используемых для анализа данных окислительного метаболизма у малых лесных мышей (Apodemus uralensis Pall.) зоны Восточно-Уральского радиоактивного следа (ВУРС). Математические методы анализа сгруппированы в три класса. Первый класс – методы учета сопутствующих переменных (конфаундеров), где наиболее корректными являются методы стандартизации путем стратификации данных и типологической регрессии; второй – методы оценки изменения взаимосвязей между показателями под действием радиации, что наглядно показано методами корреляционных плеяд и типологической регрессии; третий – методы создания многофакторного обобщенного образа организмов, обитающих на контрольной (фоновой, «чистой») и радиоактивно-загрязненной территориях, один из способов построения которого показан на примере метода линейной функции Фишера (дискриминантный анализ).

In order to systematize and generalize the statistical models used to assess the radiation exposure to biological systems, an analysis of the mathematical methods used to analyze the oxidative metabolism data of pygmy wood mouse (Apodemus uralensis Pall.) of the East Ural Radioactive Trace (EURT) zone is carried out. Mathematical methods of analysis are grouped into three classes. The first class includes methods for accounting for confounders, where the most correct methods are standardization by data stratification and typological regression. The second class covers methods for assessing changes in the relationships between indicators under the influence of radiation, which is shown by the methods of correlation pleiades and typological regression. The third class includes methods for creating a multifactorial generalized image of organisms living in the control (background, clean) and radioactively contaminated territories, one of the methods of construction of which is shown by an example of the Fisher’s linear function method (discriminant analysis).

Рассматривается решение задачи о фильтрационном поле давления в слоисто-неоднородном пласте, проницаемость которого зависит от вертикальной координаты. Пласт, вскрытый на всю толщину, и скважина представляют взаимосвязанную гидродинамическую систему. Получены аналитические решения задачи сопряжения с краевым условием в виде интегродифференциального уравнения, описывающего динамику возмущений давления в системе «скважина – пласт». Выражение, представляющее давление в пласте, позволяет установить два важнейших параметра, определяющих релаксационные процессы в скважине после пуска насоса: релаксационное давление и время релаксации. Аналитические результаты верифицированы конечно-разностными расчетами.

The solution of the problem of filtration pressure in a reservoir whose permeability depends on the vertical coordinate, opened to the entire thickness by a well, is considered. The formation and the well represent an interconnected hydrodynamic system. Analytical solutions to the interface problem with integro-differential equations describing the dynamics of pressure perturbations in the well – reservoir system are obtained. The expression that defines the reservoir pressure allows you to set two important parameters that describe the relaxation processes in the well after starting the pump: the relaxation pressure and the relaxation time. Analytical results are verified by finite-difference calculations.
