Authors: Panezai Iqra , Azeem Athar , Athar Shamaila
Published: October 2024

The study primarily aims to identify and analyze socio-cultural obstacles that prevent women from pursuing higher education in rural Quetta. It focuses on examining how women perceive the effectiveness of these barriers. This study utilized a qualitative research methodology to investigate the experiences of ten young female participants encountering socio-cultural obstacles that hindered their pursuit of higher education. The researchers conducted in-person interviews with participants using a semi-structured questionnaire, allowing for a full analysis of their experiences. The socio-cultural impediments examined include patriarchal culture, early marriages, priority for sons' education, co-education and male teachers, and social bias towards females. The findings indicate that although these obstacles exist, many young females do not view them as effective in discouraging their pursuit of higher education. This study highlights women's unfavorable situation in rural areas of Quetta, highlighting the need for more effective strategies to encourage women to pursue higher education.
Transcarotid flow reversal for proximal control during cerebral aneurysm clip reconstruction: illustrative case
Authors: Wenger Nicole M , Hentschel Matthew , Wang Ting I , Kim Kevin T , Caffes Nicholas , Cherian Jacob
Published: October 2024

BACKGROUND

Paraclinoid aneurysms can pose an operative challenge during clip reconstruction, given the complex surrounding anatomy and the aneurysmal tendency to maintain turgor despite standard approaches to proximal control. This report demonstrates the use of intraoperative retrograde arteriovenous shunting with the transcarotid artery revascularization (TCAR) system to assist in the safe clip reconstruction of an irregular paraclinoid aneurysm.

OBSERVATIONS

A 33-year-old woman presented with perimesencephalic subarachnoid hemorrhage and was found to have an incidental 9-mm ophthalmic aneurysm. Coil embolization was not successful. During microsurgical clip reconstruction, the left common carotid artery was exposed to allow for proximal control as well as transcarotid arterial sheath placement. Flow reversal was instituted throughout the aneurysm dissection and clipping, with a visible softening of the aneurysm. Intraoperative angiography confirming successful clip reconstruction was performed utilizing the TCAR sheath. The case was complicated by the development of cerebrospinal fluid rhinorrhea postoperatively, requiring surgical repair. The patient has since made a complete recovery.

LESSONS

Transcarotid flow reversal utilizing the TCAR system has potential for use in the surgical treatment of paraclinoid aneurysms, as it may aid in softening the aneurysm for safer dissection and clip reconstruction, protect against aneurysm-associated emboli, and provide an avenue for intraoperative angiography.

Primary jugular foramen fibrous dysplasia: surgically nuanced video of extradural infratemporal transjugular approach. Illustrative case
Authors: Eduardo da Silva Carlos , Clara Thibes Ana , Vidaletti Tamara
Published: October 2024

BACKGROUND

Fibrous dysplasia of the bone is a disease caused by a somatic GNAS mutation that affects craniofacial bones and can have a mass effect on different neurovascular structures. The authors present the first case of primary jugular foramen fibrous dysplasia with occlusion of the transverse and sigmoid sinuses.

OBJECTIVE

A 33-year-old man presented with a history of dizziness and occasional dysphagia over the past year. Magnetic resonance imaging showed a uniform enhanced mass in the left jugular foramen, with complete blockage of the adjacent transverse and sigmoid sinuses. The computed tomography scan revealed a cystic bone lesion of the jugular foramen. The patient underwent a gross-total removal of the tumor through an infratemporal transjugular approach with complete preservation of the lower cranial nerves.

LESSONS

This first reported case of primary jugular foramen fibrous dysplasia highlights the importance of considering this diagnosis when evaluating jugular fossa lesions. Understanding the anatomy of the infratemporal and jugular fossae, along with proficiency in microsurgical techniques, is essential for removing such tumors while preserving cranial nerve functions and the patient’s quality of life.

Published: October 2024

Space missions using small CubeSat-type spacecraft have become widespread. In this regard, integrated space networks are a promising direction for the development of this industry. In this paper, the architecture of such a network is proposed. It is planned that the first node of this network will be the ReshUCube-2 device.
Functional requirements and technical limitations of the described architecture were determined. Based on the requirements, a review and comparative analysis of network protocols and technologies of different levels: physical, channel, network, transport and application. As a result, a network stack is proposed that meets these requirements. The key protocols in the stack were chosen: LoRa, 802.15.4, IPv6, 6LoWPAN, RTL, TCP, UDP and CoAP. Methods of software and hardware implementation of network nodes are proposed. A test bench based on specially developed unified devices is demonstrated, on which it is proposed to work out the functions of network interaction. A test payload board for small spacecraft nodes of the space segment is also shown.
The results obtained will be used in the development of future space missions of the Reshetnev Siberian State University. In addition, the results can be useful in the design of the Internet of Things, the Internet of vehicles and similar networks. The results of the work can also serve as a basis for future research in the field of network technologies, digital signal processing, inter-satellite interaction and space information systems.
On the bottom layer in groups
Authors: Senashov Vladimir I.
Published: October 2024

The question of the possibility of restoring information about a group by its lower layer, that is, by the set of its elements of prime orders, is considered. The question is classical for mathematical modeling: restoration of the missing information about the object from the part of the preserved data. A group is said to be recognizable from the bottom layer under additional conditions if it is uniquely reconstructed from the bottom layer under these conditions. A group G is said to be almost recognizable from the bottom layer under additional conditions if there exists a finite number of pairwise nonisomorphic groups satisfying these conditions, with the same bottom layer as the group G. A group G is called unrecognizable from the bottom layer under additional conditions if there is an infinite the number of pairwise non-isomorphic groups that satisfy these conditions and have the same bottom layer as the group G. Results are given on the recognition of groups by the bottom layer in various classes of groups. The concept of recognizability by the lower layer was introduced by analogy with the actively studied recognizability by spectrum, that is, by the set of orders of group elements. In this paper, we consider groups that, without a single element, coincide with their bottom layer. Examples of groups with these conditions in the classes of Abelian and non-Abelian groups are given. The properties of such groups are established. The results can be applied when encoding information in space communications.

Published: October 2024

Magnetic semiconductors are widely used in microelectronics, which is used to control spacecraft. The transport and electrical properties depend on the magnetic structure, which can be changed by the action of the magnetic field and controlled by the current. The magnetic structure of semiconductors with a strong spin-lattice interaction, which is reduced to a four-spin exchange interaction, is investigated. The magnetic characteristics are calculated in a classical Heisenberg model constructed from equivalent magnetic atoms forming a simple cubic and square lattice. The Hamiltonian of the system contains the exchange interaction between the nearest neighbors, the four-spin exchange, and the one-ion anisotropy of the light axis type. The Monte Carlo method calculates the thermodynamic characteristics: the sublattice magnetization, the quadrupole parameter, the pairwise spin-spin correlation functions, the spontaneous moment at the node directed along the light axis and in the basis plane, the internal energy, and the magnetic susceptibility. The magnetic order type was found to change from a collinear antiferromagnet (AFM) to a noncollinear (NAF) as the four-spin exchange constant increases. The dependence of the spin correlation functions on the distance has a weakly damped oscillatory character. In the AFM-NAP transition region, the near antiferromagnetic order is replaced by the ferromagnetic one, while the far antiferromagnetic order is preserved. A phase diagram of the antiferromagnetic (AFM) and non-collinear (NAF) on square and cubic lattices is constructed on the four-spin exchange-single-axis anisotropy plane. The longitudinal and transverse susceptibility of the NAF from temperature for different parameters of the four-spin exchange is calculated. The region of anisotropy and quadrupole exchange parameters in noncollinear NAF with a first-order phase transition, the sublattice magnetization jump, and the quadrupole parameter from temperature are determined. The anisotropy and four-spin exchange constants in a classical antiferromagnet with spontaneous momentum and far- and near-order parameters were found.

Published: October 2024

Currently, JSC ISS named after Academician M. F. Reshetnev is working on the development of the production of billets of flexible waveguide sections (DHW) with sections from 2010 to 7030, with a wall thickness of 0.1 mm made of BrB2 copper alloy. The maximum deviation of the size of the inner channel is not more than 0.1 mm. Such methods of manufacturing DHW blanks by pressure, such as rolling and drawing, take up to 20 working shifts and include a large number of cycles (from 6 to 8), require heat treatment and etching of parts after each cycle. In this regard, the task was set to reduce the complexity of the production of DHW blanks. The solution to the problem can be welding of shells from sheet blanks on a forming device, followed by the execution of a longitudinal seam. As part of the solution of the task, the calculation of the amount of energy required to melt the edges of the part was carried out, the analysis of the possibility of assembly by various welding methods for welding thin-walled shells with exact dimensions was carried out.
The analysis of the material showed that welding should be carried out in inert media. The following methods were chosen for welding the samples: arc welding in the environment of argon protective gas with a non-melting electrode, microplasma and laser welding. In the course of the work, 30 samples of 100200 were welded, showing that 70 % of the samples are defective during arc welding and microplasma welding, while only 5 % are formed during laser welding. The following conclusions are obtained: with arc welding methods of small thicknesses, unacceptable defects occur due to the instability of the arc, whereas when using laser welding, uniform formation of the weld is observed. Metallographic studies and tensile tests were carried out on samples welded by laser welding, showing the specific strength of the weld metal at least 90 % of the strength of the base metal and the absence of defects in the cross section of the weld metal.
Features of achievement of limiting speed values of track tests of ballistic type aircraft
Authors: Astakhov Sergey A.
Published: October 2024

The development of high-speed ballistic aircraft with speeds exceeding 1000 m/s is currently a priority abroad and in Russia. The effectiveness of new such products is confirmed by track tests at the speed of their use. Test sites with rail tracks exist in almost all countries, for example in the USA there are more than 15 of them. Double-rail, monorail and various combinations thereof, differing in length, width of the rail pair, rails and the design of the track itself, including a sealed shell over the rail track to fill it with a lighter one environment. The longest track in the USA is Holloman AFB, located in New Mexico with a length of 15536 m. They have track ranges with different lengths and their own special design in England, France, Germany, Canada, Italy, Japan, India, China, Korea, Turkey and other countries, including African continent. High-speed range tests in Russia are carried out on the experimental installation “Rocket Rail Track 2500”, located on the territory of the FKP “GkNIPAS named after L. K. Safronov”. The experimental installation consists of a rail track placed on a special base, providing the necessary vertical profile of the track with sections of ascent and straight horizontal movement, as well as a technological descent section for braking moving technological equipment. The product under test is placed on a rocket track sled moving along rails on sliding supports. To accelerate the track carriage, solid fuel rocket engines are used, the thrust of which is selected based on ballistic calculations to achieve the required test speed. The length of the track plays an important role in achieving the maximum acceleration speeds of moving track equipment. The enormous aerodynamic drag, proportional to the square of the speed of movement of the carriage, when tested at high speeds, leads to the need to reduce the midsection and mass of the mobile unit. An increase in engine thrust leads to an increase in the weight and cost of track equipment, as well as to the need to increase the safety margin of sliding supports. However, an increase in test speed can be achieved by replacing the air medium with gases that have a significantly lower density, for example, helium. Track testing of new aircraft or their elements, although cheaper than flight testing, is quite expensive. In this regard, work on the theoretical assessment of replacing the medium from ambient air with helium, as well as with a mixture of helium and air at different concentrations in an indoor gallery on a track rail track, is a new, relevant and practically useful task. The work performed a numerical simulation of the problem of supersonic flow around a helium-air mixture at different volumetric ratios. Numerical values of aerodynamic resistance were obtained at a sled speed of 830 m/s. The results of numerical calculations of the motion dynamics of a 3D model of monorail track equipment, which are planned for use in conducting full-scale fire experiments, are presented.

Published: October 2024

Knowledge of the dynamic properties of thermometers is of particular importance for successful automation of process management in real time. The dynamic behaviour, i.e. the thermal response of the thermometers, is primarily determined by the thermal time constants of the thermo sensor and the protective housing in which it is located (thermo immersion probe, thermowell). In this paper, we presented a simple, but for a large number of applications acceptably accurate method of determining the thermal time constants of the temperature sensor. The procedure for determining the thermal time constants of a thermometer is shown on the example of a thermometer with a resistance temperature sensor. The paper presents the thermal model of the resistance temperature sensor and the protective housing of the sensor. By suddenly immersing the immersion probe in a container with heated water, the temperature response was recorded. Based on the presented thermal model, the thermal time constants of the temperature sensor and the protective case were determined.

Reducing ACO Population Size to Increase Computational Speed
Authors: Olivari Luka
Published: October 2024

Ant Colony Optimization (ACO) is a powerful metaheuristic algorithm widely used to solve complex optimization problems in production and logistics. This paper presents a methodology for enhancing the ACO performance when applied to Traveling Salesman Problems (TSP). By reducing the number of ants in the colony, the algorithm's computational speed improves but solution quality is sacrificed. An optimal number of ants to produce the best results in the shortest time is specific to the problem at hand and can't be defined generally. This paper investigates the effect of ant population reduction relative to the problem size by measuring its impact on solution quality and execution time. Results show that for certain problem sizes ant population and execution time can be halved with practically no reduction in solution quality, or they can be reduced 5 times at the price of slightly worse solution quality. Reduction of ant population is much more impactful on reduction of execution time than it is on solution quality.

Forecasting Daily Air Quality Index and Early Warning System for Estimating Ambient Air Pollution on Road Networks Using Gaussian Dispersion Model with Deep Learning Algorithm
Authors: Unnikrishnan Asha , Rajeswari S.
Published: October 2024

The rapid growth of the vehicle population is a major factor in heavy air pollution and public health issues. Traffic-related air pollutants (TRAPs) on roads are often much higher than ambient values, leading to high exposure levels in vehicles. This research proposes a hybrid forecasting model for early detection and early warning systems (EWS) of road networks during real-world travels. Data is collected from Kannur, Calicut, Palakkad, and Coimbatore using real-time sensors, including surrounding discussion information, activity information, vehicle speed, and stopping events. The study predicts ambient air quality (AAQ) levels on the road network using the Gaussian Dispersion model (GDM) and measures the risk sensitivity of PM10 and PM2.5 in selected regions. This helps formulate powerful prevention strategies and prevent negative health impacts. The air pollution module for predicting concentration has an innovative hybridization model that combines an improved cuckoo search (CS) and differential evolution (DE) algorithm with a stacked LSTM model to increase forecasting accuracy of six major environmental pollution levels. This model predicts the AAQ level and is effective and robust for warning one day before the pollutant event occurs based on the risk level of an ambient air pollutant from the RN.
Impact of Illuminant Metamerism on Colour Fidelity in Graphic Reproduction of Artistic Images
Authors: Bilalli Albulena , Zjakić Igor
Published: October 2024

The aim of the research was to to evaluate the quality of illuminant metamerism by using Colour rendering index through similar paintings and half-tone reproduction images within the graphic industry. Employing the methodology of visual perception and testing conducted by standard observers, the study scrutinises how different colour techniques of paintings respond to diverse light sources under standardised conditions. This investigation is pivotal for understanding the chromatic fidelity and consistency of paintings and their reproduction with half-tone colours, by measuring the grey balance field, for all images. To find the most suitable light source and to complete the colour quality, the Osram LED light at 3000 K, 4000 K, and 6500 K is used. The resulting index could be deceptive in cases of significant disparities. The American IES TM-30-18 colour rendering index (CRI) metric, quantifies illumination metamerism's ability to faithfully depict natural colours. At every stage (R1–R15), the average colour reproduction CRI must be more than 90.

Stark effect in MoSe2 monolayer heterostructure
Authors: Chernenko A. V. , Brichkin A. S. , Golyshkov G. M.
Published: October 2024

The effect of a vertical electric field on photoluminescence of a MoSe2 monolayer encapsulated with hexagonal boron nitride is investigated. In the spectra, there is a quadratic shift of the photoluminescence lines of excitons and trions from the applied potential difference, as well as a change in their intensity. It is found that the magnitude of the Stark shift significantly exceeds the theoretically predicted one. It is found that the energy distance between the trion and exciton lines in the spectra varies with the magnitude of the external field, which is due to the dependence of the density of free charge carriers in the monolayer on the field. This effect made it possible to determine the density of free charge carriers in the monolayer, which varies with the field and lies in the range from 0.3–3.4⋅1012 cm–2.

Published: October 2024

The lunar soil is an integral detector of cosmic rays (CRs) of different origin (Solar and Galactic). Analysis of the deep profiles of cosmogenic isotopes (14C, 41Ca, 36Cl, 10Be, 26Al, 53Mn) allows us to restore the intensity of CR on time scales of 3–4 half-lives of the corresponding isotope. To coordinate data on 10Be, it is required (in addition to the average flux of CRs) the presence of an additional source of accelerated particles with hard spectrum. Such a source can be, for example, an outbreak of a nearby SN 2–3 million years ago.

Published: October 2024

Methods of processing information transmitted through wireless networks with software development are investigated in the work. Innovative methods of data transmission such as optical technologies, quantum data transmission and wireless data transmission technologies are disclosed. It is noted that in the modern understanding, the concept of distributed computing defines the process of convergence (convergence) of distributed processing methods, such as GRID, cloud and fog computing, with the combination of virtual cluster systems (grid clusters, cloud clusters and fog clusters) into a single information communication and computing system . It is emphasized that, unlike cellular modems, ZigBee technology nodes have microcontrollers with a pre-installed operating system and flash memory, which allows solving simple computational tasks in real time before sending data. It is advisable to solve such tasks within the framework of a multi-agent approach, which will increase the efficiency of the use of sensor nodes and the entire sensor network. The advantages of the multi-agent technology of fog computing based on sensor nodes of the wireless network of the ZigBee standard are revealed. The method of multi-agent processing of sensory information and its main components are described. The architecture of the system of distributed sensor data processing is outlined, which includes 4 hardware and software levels: Terminal sensor nodes and controllers of measuring devices and automation devices that implement fuzzy calculations; Coordinators, sensor segment routers and cellular modems that collect, protect and transmit sensor data to the processing center; A data processing center that includes a cluster of servers for GRID calculations and a cloud data storage server; Client devices to access cloud storage, computing cluster servers, and distributed fog computing terminals. It is emphasized that indicators and forecast results can be stored on distributed sensor nodes or transmitted for accumulation in cloud storage for further extraction and intelligent processing in the GRID cluster of the data center.

The objective is to learn methods that increase the participation of minoritized individuals living in high poverty, from urban and rural areas, in STEM careers. The final goal is that these students do not stop their studies with only a two-year Associate of Science degree, and they want to continue studying in a university for at least another two or three years. This goal will be achieved by engagement through experiential learning in which students will take an introductory astrobiology/data science class that uses a Citizen Science (CS)-NASA radiotelescope. We describe the setup of the project in this proceeding, we share the main concepts learned from our students, and graphs obtained by the first generation. Likewise, we share some of our observations and recommendations to implement for the next semester that we teach the class.
Wonder and Awe observing the sky
Authors: Marques Joana B. V. , Carlin Andrew P. , Gomes Miguel
Published: October 2024

"Wonder” is well known to practitioners in astronomy education activities. Expressions of emotions, such as of awe and wonder, play an important role in engaging audiences, yet there exists no systematic study of these phenomena in the astronomy education literature. In this paper we analyse moments where these emotions are displayed – what we call “Awe Moments” – in observations with telescope. Using an interactional perspective, we analyzed 10 hours of video recordings of these events, collected in different institutions in Portugal. The way these emotions are produced interactionally by guides and the public is described. The data show that these interactions are recurrent and that guides and public validate, enhance and prolong these emotional moments. This work contributes to the literature on emotions in educational settings, to the training of guides and the evaluation of astronomy educational events.
Autonomous Second-Order ODEs: A Geometric Approach
Authors: Pan-Collantes Antonio J. , Álvarez-García José A.
Published: October 2024

Given an autonomous second-order ordinary differential equation (ODE), we define a Riemannian metric on an open subset of the first-order jet bundle. A relationship is established between the solutions of the ODE and the geodesic curves with respect to the defined metric. We introduce the notion of energy foliation for autonomous ODEs, and highlight its connection to the classical energy concept. Additionally, we explore the geometry of the leaves of the foliation. Finally, the results are applied to the analysis of Lagrangian mechanical systems. In particular, we provide an autonomous Lagrangian for the damped harmonic oscillator.
Facilitating Well-Founded Criticism of Established Scientific Paradigms
Authors: Traunmüller Hartmut
Published: October 2024

This is a preliminary editorial of a publication platform “_Well-Founded Extraordinary Science_”. It describes the problem this medium is meant to solve and presents the attempted solution. Scientific innovations often struggle to pass through peer review and regularly fail under certain circumstances: In its theoretical aspects, science is believed to progress through criticism and falsification, but where a dominant theoretical framework is established, expert reviewers practically only allow its _completeness_ to be questioned. Falsifications are frequently bypassed by ad hoc modifications. Criticism, even if fatal, can be turned a blind eye. This blocks fundamental scientific progress. An article about cosmology with published reviews highlights this issue. There, a critical evaluation is suppressed despite evident contradictions in the standard approach. As a countermeasure against similar cases, this open access medium with published reviews promotes epistemic progress by challenging established wisdom. It accepts only well-founded studies that go against established assumptions, theories or methods. Besides criticism of established paradigms, it promotes innovations or ‘revolutions’ that are well-founded and parsimonious. Reviewers are guided to check each claimed deficiency and innovation, whereby their confirmation bias is bridled. It is acceptable to present criticism without elaborating innovations and innovations without elaborate criticism of the established framework.

СУТНІСТЬ ТА ОСОБЛИВОСТІ ЕЛЕКТРОЕНЕРГЕТИКИ ЯК ОБ’ЄКТУ АДМІНІСТРАТИВНО-ПРАВОВОГО ВПЛИВУ
Authors: ТОЛЧІНІНА-БУРУНСЬКА Ю.Ю.
Published: October 2024

У статті наголошено на тому, що електроенергетика як об’єкт адміністративно-правового впливу розглядається у вітчизняній адміністративно-правовій доктрині крізь призму електронного урядування. Сутність електроенергетики як об’єкту адміністративно-правового впливу зводиться до суспільних відносин із зберігання, агрегації, передачі, розподілу, купівлі-продажу, передавання, використання, вимірювання та заощадження, у тому числі в рамках міжнародного співробітництва, електроенергії, а також вирішення низки проблем у сфері публічного управління, пов’язаних із формуванням у публічних службовців та всього населення України культури енергозбереження, розвитком енергоменеджменту, енергоефективності та екологічності у вітчизняній електроенергетиці. Наголошено, що ще однією особливістю електроенергетики як об’єкта адміністративно-правового впливу є адаптивність та відкритість до інновацій, що проявляються як на рівні поведінки споживачів електроенергії, так і на рівні публічного управління у сфері електроенергетики. Під адміністративними інноваціями в контексті дослідження визначено не лише зміни в правилах і структурах, але і комплексне, багатоаспектне, сутнісне переосмислення на основі вітчизняної і зарубіжної доктрини, досвіду провідних держав світу завдань та функцій, предмету та меж, системи суб’єктів, адміністративних інструментів та інших важливих аспектів публічного управління в сфері електроенергетики.
ПОЛІТИКА РЕІНТЕГРАЦІЇ ТИМЧАСОВО ОКУПОВАНИХ ТЕРИТОРІЙ УКРАЇНИ ТА ЇЇ ПРАВОВІ ОСНОВИ
Authors: МІНАКОВА Є.В.
Published: October 2024

У статті надано характеристику політики реінтеграції тимчасово окупованих територій України та її правових основ з метою вироблення пропозицій щодо її удосконалення. Реінтеграції тимчасово окупованих територій України притаманний політичний контекст. Реінтеграція є одним із ключових завдань української державної політики, що насамперед потребує ретельної підготовки та визначення механізму подолання внутрішніх і зовнішніх ризиків. Зазначено, що політика реінтеграції тимчасово окупованих територій України не отримала комплексного врегулювання в окремому нормативно-правовому акті. Необхідним є прийняття закону про реінтеграцію деокупованих територій та ухвалення відповідних підзаконних нормативно-правових актів. Ухвалення Концепції реінтеграції деокупованих територій, а також стратегічних документів щодо інформаційної та економічної політики на деокупованих територія є логічним продовженням такого політичного рішення. Доведено, що громадська участь у політиці реінтеграції тимчасово окупованих територій України сприяє прозорості, справедливості та ефективності політичних рішень, а також зміцненню суспільної довіри. Зроблено висновки, що формування політики реінтеграції тимчасово окупованих територій України є важливим завданням, яке вимагає комплексного та системного підходу. Політика реінтеграції повинна ґрунтуватися на Конституції України та бути визначеною в окремому законі України, крім того важливі чіткі і послідовні стратегічні підзаконні нормативно-правові акти. В процесі формування та реалізації політики реінтеграції тимчасово окупованих територій важливо використовувати переваги комунікації між державою і громадянським суспільством. Ефективна політика реінтеграції повинна спиратись на якісну інформаційну політику, забезпечувати відновлення інфраструктури та стимулювати економічний розвиток деокупованих територій.
СИСТЕМА СУБ’ЄКТІВ ЗАБЕЗПЕЧЕННЯ РЕЖИМУ ВОЄННОГО СТАНУ В ДЕРЖАВІ ТА МІСЦЕ І ОСОБЛИВОСТІ У НІЙ ВІЙСЬКОВИХ ДЕРЖАВНИХ АДМІНІСТРАЦІЙ

Published: October 2024

У статті, на основі аналізу наукових поглядів вчених, запропоновано авторське визначення поняття «суб’єкти забезпечення правового режиму воєнного стану в Україні». Розкрито положення норм чинного законодавства, на основі чого сформовано авторський підхід щодо визначення кола відповідних суб’єктів. Акцентовано увагу на тому, що військові державі адміністрації займають особливе місце в системі суб’єктів забезпечення режиму воєнного стану. Наголошено, що суб’єкти забезпечення правового режиму воєнного стану в Україні – це сукупність спеціально уповноважених органів державної влади (в особі їх посадових осіб), які відповідно до норм чинного законодавства наділені особливим правовим статусом (набором спеціальних суб’єктивних прав та юридичних обов’язків), що дає їм можливість здійснювати різноманітні юридичні, організаційні, матеріально-технічні, інформаційні, фінансово-економічні та інші засоби, спрямовані на формування та підтримку умов для ефективного функціонування відповідного правового режиму. Аргументовано, що на сьогоднішній день існує багато цілком різноманітних за своїм правовим статусом, але активно взаємодіючих між собою в процесі виконання функціональних завдань, суб’єктів забезпечення воєнного стану в Україні. Кожен з них має власну юридичну роль у створенні та підтримці умов роботи досліджуваного правового режиму. Обґрунтовано, що відмінністю саме військових адміністрацій від інших суб’єктів є те, що вони уповноважені забезпечувати не тільки умови та інші аспекти функціонування механізму воєнного стану в цілому, але також процес реалізації заходів цього правового режиму, передбачених Законом України «Про правовий режим воєнного стану». Ця унікальна ознака свідчить про концентрацію в правовому статусі військових адміністрацій всієї повноти публічної влади в межах території, на якій введено правовий режим воєнного стану, адже вони відповідають і за навколишню організацію останнього, і за практичну реалізацію його механізму.
UTOPIA E CONSCIÊNCIA MESTIÇA
Authors: Madella Thayse
Published: October 2024

Este artigo pretende revisitar o romance feminista utópico Woman on the Edge of Time (1976), de Marge Piercy, por uma perspectiva feminista pós-colonial. Muitas feministas dos anos de 1970 usaram o gênero de ficção científica como um ato revisionista para criticar o discurso patriarcal. Cerca de quatro décadas mais tarde, uma nova visita revisionista se faz necessária. Para tanto, minha análise leva em conta a afirmação de Gloria Anzaldúa de que o futuro pertence à mestiça. Meu argumento discute como a protagonista, Consuelo Ramos, encontra-se em posição subalterna devido às opressões a que é sujeitada e é esta marginalização que a possibilita alcançar o estado de Coatlicue e viajar ao futuro. Ao viajar por territórios separados não pela geografia, mas pelo tempo, o romance representa o que seria este futuro da mestiça.
