Atomistic Simulation of Primary Radiation Damage Profiles in Fluorine-Doped Tin Oxide Thin Film Target Using SRIM Code
Authors: Oryema Bosco , Madiba Itani G. , Mtshali Christopher B.
Published: November 2024

In this study, we investigated the discrepancy between the numbers of atomic displacements obtained from the Vac.txt method and those obtained from the Vac.dam method using SRIM-2013 operated in full cascade mode. The SRIM simulations also calculated energy partitioning, damage dose and distribution profiles of the implanted He, C and O ions at three different ion energies of 10 keV, 100 keV and 1 MeV. In all the simulations and at each ion energy value, the target thickness was increased until the entire ion beam was absorbed within the target. The simulated fluorine-doped tin oxide (FTO) thin film target stoichiometrically comprised 78.6% Sn, 16.4% O and 5.0% F, and a 6.013 g/cm3 bulk density. To achieve relatively good statistics with compromised computational time, each run followed 10 000 ion histories. The results indicated that, with increasing ion energies, the peaks of vacancy concentrations moved deeper into the material. For He ions, the vacancy profiles have peaks at ∼0.04, ~0.45 and ~2.9 µm at 10 keV, 100 keV and 1 MeV, respectively. Meanwhile, for C and O ions, the peaks were at ∼0.012, ~0.15 and ~1.23 µm for C ions and ∼0.01, 0.12 and 1.2 µm for O ions at 10 keV, 100 keV and 1 MeV, respectively. We also observed that for all the ions and at all ion energies considered, the Vac.txt method predicted more vacancies than the Vac.dam method, and the discrepancies generally increased with increasing Z by an average value of ∼1.21, ∼1.45 and 1.48 for He, C and O ions respectively. In addition, the electronic and nuclear partitioning profiles revealed that most of the energies of the ions were lost in collision with atomic electrons due to ionisation and excitations, and little to nuclear events. The simulations also revealed that nuclear stopping powers increase at low ion energies. This study also indicated that damage dose profiles strongly depend on the type of incident particle and its energy. A comparison of SRIM and iradina calculated vacancies and incident ion distribution profiles generally indicated perfect agreements between the two codes. FTO thin film remains a promising material for thermal control applications in future spacecraft. However, further analyses are still necessary to comprehensively understand its evolution under intense radiation environments comprising various ions and at different energies.

Published: November 2024

One of the prospects for a wealth of geological resources that can be utilized for the benefit of mankind is manganese metal mineral resources. In Anabanua Village, especially at the research location, there is an indication of manganese mineralization that the type of rock carrying the mineralization is not yet known. The purpose of this study was to determine the chemical elements of metallic minerals, mineralogy, and types of mineralization-carrying rocks, as many as three samples in the form of chunks, which were analyzed using megascopic analysis methods identifying the texture and structure of carrier rocks, XRD (X-Ray Diffraction) analysis minerals, and XRF (X-Ray Fluorescence). The characteristics of manganese mineralization carrier rocks consist of metallic elements Mn (0.046%-20.455%), Fe (1.555%-3.673%), and nonmetallic elements SiO2 (11.403%-48.165%), K2O (0.398%-4.177%). Mineralogy of manganese mineralization carrier rocks are roeblingite (Pb2Ca6Mn2+(Si3O9)2(SO4)2(OH)2·4H2O), rhodonite (CaMn3Mn[Si5O15]), diopside (CaMgSi2O6), calcite (CaCO3), kieserite (Al, Ga)2(GeO4)(OH)2), zeolite (Mn2O.Al2O3.xSiO .yH2O), and palygorskite ((Mg, Al)2 Si4O 10(OH)·4H2O). Manganese mineralization host rocks are determined by referring to the SiO2 (%weight) and K2O(%weight) diagrams to produce basalt igneous rock types.
Inclusion scolaire : au-delà des « étiquettes », identifier les profils d’élèves pour enseigner le français et la littérature à tous
Authors: AMIOT Leslie
Published: November 2024

Alors que l’inclusion scolaire est un droit pour tous les élèves quels qu’ils soient depuis 2005, elle peine encore parfois à se mettre en place au sein du système scolaire et particulièrement dans le secondaire. Si les élèves à besoins éducatifs particuliers sont présents dans les classes, les apprentissages ne leur sont pas toujours accessibles et les échecs sont nombreux. Cette étude menée auprès de 131 élèves de 3e dans un collège rural s’est intéressée à caractériser des profils de classe (plutôt que des profils d’élèves) à partir de questionnaires permettant aux enseignants de ces classes d’optimiser l’hétérogénéité et de l’appréhender comme une richesse pour leur mise en œuvre pédagogique. Les résultats montrent que les élèves étudiés ne présentent pas nécessairement le profil le plus pertinent pour développer les compétences linguistiques en français mais les analyses nous permettent de faire ressortir d’autres points d’entrée pouvant être des leviers au développement de ces compétences. La formation nous apparait comme une clé essentielle.

Authors: DICHARRY-POMAREZ Sandrine
Published: November 2024

L’éducation inclusive invite tous les acteurs éducatifs à s’engager dans une disposition à l’inclusion. Cette perspective conduit les enseignants à faire face au malentendu issu des interactions professionnelles. Nous avons mené une recherche qualitative et longitudinale avec des enseignants stagiaires et des enseignants spécialisés se formant au Certificat d’aptitude professionnelle aux pratiques de l’éducation inclusive (Cappéi). Les résultats apportent une lecture sur les manières d’être et les manières de faire de l’enseignant spécialisé/inclusif se réalisant dans la quête d’une évolution personnelle et professionnelle. Ils conduisent vers la projection d’un sujet, capable de se faire confiance et d’être soi dans une relation professionnelle qui fait face à un malentendu.

Despite numerous potential advantages of oxetanes, their restricted synthetic accessibility and propensity to ring-opening hampers their wide application in drug design. In this work, we disclose our 10-year experience in oxetane chemistry and provide a comprehensive analysis of the oxetane core tolerance towards the reaction conditions of the typical toolbox of organic and medicinal chemists. The scope includes oxidation, reduction, alkylation, acylation, nucleophilic substitution, C–C/C=C/C≡C bond formation, hydrolysis and protecting groups cleavage, and also demonstrates the stability of the oxetane's moiety towards acidic and basic conditions. Over 30 transformations were applied to generate the oxetane chemical stability profile and prepare novel 3,3-disubstituted oxetanes as accessible small building blocks (over 100 examples). The work's additional aim included optimizing the synthetic protocols with the possibility of scaling on up to 1 kg in a single run, also addressing the potential instability of the oxetane ring. These results benefit the development of oxetanes as a part of the toolbox of modern medicinal chemistry, as well as their incorporation into drug development programs.

Published: November 2024

The ubiquity of C–H bonds in organic molecules makes C–H functionalisation one of the most valuable synthetic transformations in organic chemistry. It provides a sustainable synthetic strategy, optimising atom and step economy by eliminating the need for functional handles, instead relying on reagent control or the substrate’s innate selectivity. C–H alkylation of electron-poor aromatic species remains a particular challenge, typically relying on functional handles to direct selectivity with either traditional palladium cross-coupling or nickel photoredox methodologies. Here we introduce a highly selective, scalable, and cost effective synthetic strategy for C–H alkylation of electron-poor aromatics, exhibiting high functional group tolerance applicable to pharmaceutical compounds. This reaction leverages an autocatalytic, electron donor-acceptor triggered, radical reaction, as confirmed by both experimental and computational analyses. Notably, it demonstrates ‘anti-Friedel-Crafts’ selectivity, consistent with theoretical predictions from Fukui indices and machine learning models on previously ‘unseen’ substrates.
Design and Evaluation of Dansyl-Derived Chemosensors for Disulfide-Cleavage-Triggered Detection: Photophysical, Metal Sensing, and Thermometric Applications
Authors: Lourenço Igor , Duarte Frederico , M. Dobrikov Georgi , Kurutos Atanas , Capelo-Martinez José Luis , Santos Hugo M , Lodeiro Carlos
Published: November 2024

In this work, two new dansyl-derived chemosensors have been designed with the aim of developing a disulfide-cleavage-triggered probe. These stable new ligands, containing a thioether (L1) and a disulfide bridge (L2), have been synthesized and evaluated for their photophysical properties in both solution and solid state. Different fluorescence emission responses have been observed for both compounds due to the self-quenching nature of the disulfide bond compared to L1, with the latter reaching quantum yields close to 50%. Efforts to characterize solute-solvent interactions through Kamlet-Taft studies have revealed a positive solvatofluorochromic response for both compounds. Furthermore, the aggregation-induced emission phenomenon was demonstrated at increasing water fractions. The presence of free thiol groups enhances the complexation ability, making L1 particularly beneficial for sensing Cu²⁺ and Hg²⁺ ions, achieving detection limits as low as 2 µM in the case of mercury. Finally, incorporating L1 into polymer-doped films demonstrated promising results as molecular thermometers, while the response of L2 to sodium dithionite underscores its potential in disulfide-cleavage-triggered applications.
Nickel-Catalyzed [4+1] Sila-Cycloaddition: A Divergent Synthesis of Silacarbocycles from Trichlorosilanes
Authors: Qi Liangliang , Xu Peng-Fei , Wu Yu-Ke , Pang Xiaobo , Shu Xing-Zhong
Published: November 2024

Cyclic chlorosilane transformations present a valuable opportunity for the divergent synthesis of silacarbocycles, but their low availability has hindered this potential. This study presents a direct approach to producing structurally diverse five-membered cyclic chlorosilanes, utilizing trichlorosilanes as a novel Si–1 synthon for catalytic sila-cycloaddition reactions. The method employs a nickel-catalyzed [4+1] cycloaddition reaction between 1,3–dienes and trichlorosilanes, facilitated by upgraded phosphine-nitrogen ligands. This approach accommodates a broad range of 1,3–dienes and trichlorosilanes, yielding cyclic chlorosilanes that act as versatile platform molecules. These intermediates can be readily transformed into advanced silicon reagents and connected with various carbon and heteroatom functionalities through a one-pot reaction.
Enzymatic metal-hydrogen atom transfer with a cobalt protoporphyrin cofactor

Published: November 2024

Biocatalysts are prized for their selectivity, tunability, and their compatibility with environmentally-friendly reaction conditions. Introduction of unnatural cofactors opens the door to new reactive enzymatic intermediates, and in turn, the possibility for new biochemical reactions. In the present study, we employed a de novo biosynthesized, non-natural cofactor, cobalt protoporphyrin IX,1 to generate a mono-nuclear cobalt hydride intermediate in the active site of a common P450 scaffold. We show that this cobalt hydride intermediate engages in metal-hydrogen atom transfer (M-HAT) reactivity, a well-studied and highly utilized reactivity pattern in synthetic chemistry,2 but which is not known to operate in nature. Because the required cofactor is fully biosynthesized and incorporated into proteins in vivo, the catalysts are highly amendable to directed evolution. We leveraged the ability to quickly access these new artificial metalloenzymes with a colorimetric screen and evolved new variants for M-HAT-mediated deallylation of phenols. We showed how common silanes have a propensity to hydrolysis that can be overcome with directed evolution by accelerating metal-hydride formation from a bulky, water stable silane. During this evolution, we discovered that variants were catalyzing HAT to the colorimetric probe itself, resulting in a unique reductive dearomatization reaction. This radical process occurs efficiently under aerobic conditions and reactions of this type have not been observed previously. These discoveries demonstrate how the tunability of biocatalytic systems can enable innovations in synthetic chemistry. We anticipate that further engineering and study of M-HAT biocatalysts will prompt new questions about hydrogen atom transfer reactivity and enable the adoption of biocatalysts for numerous synthetically useful transformations.
Cells Respond to ECM Contexts via Integrin-Ligand Lifetimes: Rediscovery of Loading Rate Enhancement through Bayesian Refinement of Force Spectrum Analysis
Authors: Yang Xueyi , Zhang Xu , Xu Yue , Guo Chuanwen , Gao Shenghan , Jin Huitong , Yang Chun
Published: November 2024

The phenomenon of loading rate enhancement, where the bond lifetime between protein molecules significantly increases beyond a certain loading rate threshold, has been well-documented across various molecules. However, reports of this phenomenon as a mechanosensing mechanism in cells are scarce, primarily because most reported thresholds exceed physiological norms. In this study, we reevaluate the kinetic properties of integrin-ligand bonds using Single-Molecule Force Spectroscopy and Single-Cell Force Spectroscopy. Our analysis revealed a nonlinear relationship between loading rate and rupture force, with thresholds significantly below the commonly reported 10,000 pN/s. Using a Bayesian-inference-based Micro-interval analysis method, we determined specific loading rate thresholds for integrin α5β1 and α2β1 ligand-binding bonds at 1018.49 pN/s and 2398.23 pN/s, respectively. Given that substrate rigidity correlates with loading rates upon integrins under actomyosin-generated forces, our findings suggest that integrin α5 mediates stronger adhesions on softer substrates compared to integrin α2. These findings demonstrate that integrin-mediated cell adhesion strengthens within physiological loading rate ranges and suggest a mechanism for the subtle regulation of extracellular matrix protein composition in cellular elasticity sensing.

Authors: Odock Stephen Ochieng , Mutua Daniel Mutie , Ndungu Charles , Mwangi Moses
Published: November 2024

Objective: The objective of this study was to determine the effect of green logistics practices on performance and mediating effect of environmental performance on this relationship in logistics companies in Kenya.
 
Theoretical Framework: This study is anchored on the resource-based view and the natural resource-based view.
 
Method: The study employs cross-sectional survey research design. A structured questionnaire is used to collect data from a sample of 300 firms which is analyzed using CB-SEM.
 
Results and Discussion: Study establishes a significant positive relationship between green logistics practices and performance which is in line with the argument of the natural resource-based view. Secondly, the mediating effect of environmental performance on the relationship between green logistics practices and firm performance is found to be non-significant.
 
Research Implications: The study recommends that logistics firms should implement environment-friendly practices of green packaging, route optimization, fuel efficiency, carbon emission measurement and reverse logistics. The expenses associated with implementing these practices impede the firm’s ability to improve performance in the context of a developing country. The findings provide a basis for the development regulatory framework in pursuit of environmental sustainability.
 
Originality/Value: Research on ecological sustainability has mainly concentrated on the entire supply chain. This study concentrates on the logistics aspect which is responsible for a quarter of emissions of Green House Gases (CHGs). The research employs a measurement model of green logistics practices construct in the service sector hence moving away from the manufacturing organizations.
Can a Signboard Be Exclusionary? A Study of Linguistic Landscape in the Commercial Center of Poznań
Authors:   Adam Mickiewicz University in Poznań, Piekarski Mateusz
Published: November 2024

A signboard is an element of the linguistic landscape of a given place. The linguistic landscape is a space open to everyone, but it may be experienced differently by people from various generations. To examine the extent and quality of comfort or discomfort resulting from linguistic exclusion in public spaces, in the article the linguistic landscape of the center of Poznań is analyzed in terms of the absence and presence of the native language of residents and visitors to this place. The research material comes from the most frequented places in this city and includes signs of private establishments (“bottom-up tokens”), which contribute to the linguistic landscape of Poznań. The study of linguistic exclusion takes into account the diverse linguistic competencies of five living generations of Poles. It aims to identify potential causes of the feeling of exclusion in open urban spaces for specific groups of Poles.

All emergency department personnel are familiar with this scenario: 18-month-old boy presents to the emergency department at 2 a.m. on December 18. Parents look worried, yet they are baffled. As they tell their story, they are almost apologetic, “Really, he was much worse at home, he seems so much better since we drove to the hospital. He woke up in distress, he couldn’t breathe and he was making this awful noise when he took a breath in. And his cough – I’ve never heard anything like it – he sounded like a dog... or no, more like a seal. Really, it was terrible!”
There, in mom’s arms, is a happy, quiet boy looking around. When you try to examine him, his cry is stridorous and you hear the bark... reassuringly you smile back at the mom. “Yes, we know, and no we don’t have magic doors. HE HAS CROUP.”
Sexual assault and alcohol use: Where should intervention begin?
Authors: Robb Sue
Published: November 2024

Sexual assault nurse examiners and other advocates who provide specialized care to victims of sexual assault recognize the role that alcohol plays in sexual assault. Conservative estimates indicate that approximately 50% of sexual assaults occur under the influence of alcohol, making the issue of alcohol use a significant vulnerability issue. The question has been raised in current literature about the feasibility of addressing the problem of alcohol abuse in the emergency department (ED) during the sexual assault exam. Although the opportunity exists for an intervention due to the dedicated
nature of the SANE programming, is the ED an appropriate venue for such an intervention? The potential for discussion on voluntary alcohol consumption being perceived as victim blaming and concerns with what can be cognitively processed during the acute phase of crisis requires closer scrutiny before intervention models are established.
Injury documentation: Using the BALD STEP Mnemonic and the RCMP Sexual Assault Kit
Authors: Carter-Snell Cathy
Published: November 2024

Injury assessment, nomenclature and documentation vary widely across emergency departments. The Royal Canadian Mounted Police (RCMP) has forensic laboratories across Canada and performs the majority of testing of evidence for Canadian victims of sexual assault outside of Ontario or Quebec. Most emergency nurses are familiar with the large box the RCMP officers bring for the documentation and collection of evidence after sexual assault. Fewer are familiar with the inner contents of the kit or documentation. The sexual assault kit and documentation are now undergoing change, with a new kit soon to be released. The RCMP forensic laboratories identified the need for kit changes due to equipment updates and research related to quality and best practices. Some health care professionals across the country and representatives of Making a Difference Canada were consulted for suggestions on documentation and kit contents. Mount Royal University’s Forensic Research Network (www.mtroyal.ca/forensicresearch) will be developing free educational materials on the kits and use of contents in preparation for the release of the new kits (hoped to be late 2011, but not yet determined). In the meantime, the focus of this article is to introduce emergency nurses to a few key changes in documentation and evidence collection they may anticipate. The largest of these changes is the adoption of a mnemonic phrase to aid in standardization of injury documentation and assessment known as BALD STEP.

Published: November 2024

No existe suficiente investigación para comprender el ciclo del N en bosques de Pinus harwtegii. Es importante conocer el movimiento de N en los bosques para proponer estrategias de manejo forestal sustentadas en el conocimiento de procesos biogeoquímicos. Este trabajo muestra resultados de un experimento de fertilización con árboles jóvenes de Pinus harwtegii para estudiar la absorción de dos formas de nitrógeno, amonio y nitrato. Se usaron dos fuentes con 15N, sulfato de amonio y nitrato de potasio, enriquecidas al 49.2 y 56.7%, respectivamente. Los factores de variación incluyeron dos niveles de elevación (3500 y 3900m) y dos exposiciones (noroeste y suroeste), con un experimento factorial 23. Adicionalmente, se evaluó la evolución de la mineralización N anual del suelo superficial (10cm) en los mismos sitios. Los resultados indicaron que el porcentaje de nitrógeno foliar, derivado de las fuentes con 15N (NDDF), fue mayor al suroeste. Sin embargo, la recuperación neta en masa de 15N fue mayor al noroeste (P<0.05), debido a mayor masa foliar en esta exposición. La absorción de nitrato superó a la de amonio en 63% (P<0.05). La mineralización de N del suelo, con respecto a la elevación y exposición, no mostró una tendencia definida. P. hartwegii se adapta a las condiciones estacionales para la adquisición de ambas formas de N, lo que le ha permitido la colonización de sitios adversos de alta montaña. Los rodales de P. hartwegii de baja elevación (3500 m) y con exposiciones suroeste son más susceptibles a alteraciones del ciclo del N.

Se estudió la supervivencia y crecimiento del Pinus cembroides Zucc. en el ejido La Tapona municipio de Galeana, Nuevo León, con el objetivo de evaluar el efecto de las terrazas individuales y tinas ciegas en la supervivencia y crecimiento en diámetro basal, altura total y diámetro de copa de una plantación de 10 años. Se evaluaron 13 transectos (en curvas de nivel) de cada uno de los tratamientos (26 en total), mediante un diseño de muestreo sistemático aleatorio. De cada uno de los transectos se tomó información de todos los individuos, como el diámetro a los 10 cm de la base, la altura total (m) y el diámetro de copa (m). Para determinar si existían diferencias significativas en la supervivencia de la especie con respecto a los diferentes tratamientos (terrazas individuales y tinas ciegas), se realizó un análisis de varianza utilizando la prueba t de Student y la prueba de U de Mann-Whitney para las variables de altura, diámetro a los 10 cm y el diámetro de copa. Los resultados indicaron un promedio general de supervivencia del 52.69%; mientras que en tinas ciegas fue de 53.71%, y en las terrazas individuales se obtuvo el 51.68%. Sin embargo, las pruebas determinaron la ausencia de diferencias significativas en el crecimiento de los individuos dentro de las obras de conservación.
Observaciones fenológicas en clones de Pinus patula Schltdl. & Cham.
Authors: Velasco-Hernández Sara Irene , Muñoz Gutiérrez Liliana
Published: November 2024

La falta de sincronización floral en un huerto semillero propicia la disminución de la diversidad genética del lote de semillas, aumenta el porcentaje de óvulos abortivos y de semillas vacías. Por lo anterior, es necesario determinar las etapas fenológicas y el grado de sincronización entre la dispersión del polen y la receptividad femenina. En un huerto semillero asexual de Pinus patula de generación 1.5, se estimaron las fechas de inicio, fin y duración de cada etapa fenológica de las estructuras reproductivas masculinas y femeninas con el macro SYNCHRO de SAS®. El periodo de receptividad femenina duró 13 días en promedio y el de dispersión de polen 27.5 días. La dispersión de polen y receptividad femenina ocurrieron cuando se acumularon 370.5 y 440 grados-día, respectivamente. El Índice de sincronización general del huerto se considera bajo (PO=0.24), por lo que no existe una total sincronización entre los pares de clones. Se verificó correlación positiva entre el inicio y la duración de ambos eventos fenológicos (r=0.41) con sincronía de siete días; por tanto, es posible que se lleve a cabo la polinización entre los clones del huerto con índices de sincronización moderados (PO entre 0.30 a 0.60), pero se requiere determinar la variabilidad y control genético de los clones en evaluaciones subsecuentes.

Luigi Balugani l’esplora(pit)tore alle sorgenti del Nilo
Authors: Vigliotti Luigi
Published: November 2024

In the second half of the 18th century, the Bolognese draftsman Luigi Balugani joined the explorer James Bruce in an expedition aiming to document the antiquities of North Africa. Having been the first to utilize a “camera obscura” on the field, Bruce and Balugani can be considered pioneers of photoreportage, since they created the first visual documentation of this kind in history. Today these drawings are housed in the Royal Collection at Windsor. Later, the expedition ventured into the Middle East before shifting its focus toward the source of the Nile river. Travelling through Egypt, Arabia, and Abyssinia, Balugani produced over 300 drawings of plants and animals, which are now preserved at the Center for British Art at Yale University. Bruce and Balugani reached the source of the Blue Nile on November 4th, 1770, but in March 1771 the untimely death of Balugani left all the honors to Bruce, who did not fully recognize the talent and contributions of the Bolognese draftsman.
The King’s Mellifluous Tongue
Study, Social Bonding, and the Making of Middle Armenian as a Language of the Elite in Medieval Cilicia
Authors: Pifer Michael
Published: November 2024

This article on social history examines the study of Middle Armenian manuscripts at the Cilician court, placing the language’s development within a Mediterranean context that includes Outremer French and Byzantine Greek. In particular, it argues that King Het‘um I (d. 1270) bolstered his status as educated king through the commission of two works from theologian Vardan Arewelc‘i (d. 1271): an encyclopedic compendium and commentary on grammar, which aided vernacular study in different ways. By balancing the microhistory of these manuscripts against the macro-history of Cilician Middle Armenian’s configuration in writing, this article shows how vernacular Armenian became an object of elite study, seemingly capable of representing all the knowledge in the world.

Authors: Saraç Hakan
Published: November 2024

Currently, it is not enough for university graduates to acquire only occupation-specific academic knowledge to find a job. Graduates are also expected to possess an additional set of skills called employability skills. In this study, job vacancies were analyzed to determine the skills employers want from new graduates. In this study, 178 job posts for new graduates on an online job search platform (Kariyer. net) were analyzed using content analysis. According to the findings of the study, fewer hard skills and more soft skills were demanded by recent university graduates. The most demanded skills for both associate degree and bachelor's degree graduates were skills in social and communication groups. When examined in detail, the highest-demanded soft skills include "strong communication skills,” "predisposition to teamwork,” "planning and organization skills,” "effective written and oral communication skills.” In addition, "mastery of MS Office applications, knowledge of foreign languages and "knowledge of computer programs related to the field" are among the technical skills that graduates require. This research is expected to guide new graduates in terms of which skills they should develop and educational institutions in terms of updating their curricula in line with the demand for skills.

Published: November 2024

The article is devoted to the analysis of cash flows in the enterprise management system. The concept of "cash flow" is considered, which is an important subject of management, which is presented in non-cash and cash forms, the direction of which is related to the functioning of money and the monetary system, the stage of managing the company's monetary calculations. In the analysis of monetary calculations, the main goal is to determine the reasons for the deficit or surplus of monetary resources, the order of their receipt and the direction of spending in order to control the current solvency of the enterprise. The following methods are used to determine cash flows: indirect and direct. They differ in a different sequence of actions by which the size of the flow of cash is estimated. The movement of cash means the breakdown of incoming and outgoing cash flows in the development of operational, investment and financial activities of a business entity.  The flow of cash from operational and financial activities was analyzed. It was determined that an important area of ​​activity of the company's management, especially in periods of financial crises, is the management of cash flows. The dynamics of cash flow according to the sources of their formation are analyzed. It has been proven that the flow of funds from the main activity correlates with current operations, which include revenue from sales, payment of supplier invoices, receipt of short-term credits and loans, payment of wages, settlements with the budget. The flow of cash from operational and financial activities was analyzed. We consider the management of cash flows, which are detailed in monetary calculations, to be the most important activity of the company's management, especially in periods of financial crises, therefore, the reasons for the importance of such an asset, such as cash, have been determined. Disadvantages revealed after monitoring cash flows. In order to improve the cash management system, we suggest implementing a control formation that will ensure the consolidation of control actions, its concentration on the determined course of the company's financial activity, timely disclosure of deviations of the actual results from the expected ones, and the formulation of operational management decisions that will ensure its normalization.
LOCAL SELF-GOVERNMENT AS A CATALYST FOR THE DEVELOPMENT OF SOCIAL ENTREPRENEURSHIP
Authors: Samoilenko Larysa , Kravchenko Olena , Kulybaba Zoreslav
Published: November 2024

Objective and relevance. The purpose of this article is to study the role of local self-government in the development of social entrepreneurship in Ukraine, in particular in the context of decentralisation. In many countries, including Ukraine, local governments play an important role in stimulating the development of social entrepreneurship. In the context of decentralisation in Ukraine, local communities have been empowered to manage their resources, which opens up new opportunities to support businesses focused on the public good. This article explores how local self-government can become a catalyst for the development of social entrepreneurship, looking at both the opportunities and challenges of this process. As local communities gain more autonomy in managing their resources and addressing local issues, social entrepreneurship becomes a key tool for addressing social, economic and environmental challenges. This topic is highly relevant given the ongoing decentralisation reforms in Ukraine, the social and economic impact of the war, and the potential of social enterprises to contribute to sustainable community development.
This study uses a combination of qualitative and quantitative methods. The authors reviewed the literature on social entrepreneurship theory and practice, as well as examples of successful social enterprises in Ukraine and abroad. Interviews with local authorities and social entrepreneurs were used to collect primary data. In addition, a comparative analysis of the legal and regulatory framework for social enterprises at the local level was conducted.
This study shows that local governments can play a significant role in promoting social entrepreneurship through financial support, simplifying administrative procedures, and facilitating partnerships between the private sector and civil society organizations. However, challenges remain, including limited financial resources, bureaucratic barriers, and a lack of awareness of the potential of social entrepreneurship among both local officials and the public.
This article provides practical recommendations for local authorities to strengthen their support for social entrepreneurship, including the development of targeted grant programs, educational initiatives and cooperation projects with the private sector. By implementing these measures, local authorities can contribute to solving pressing social problems while stimulating economic growth and innovation at the community level.
THE ROLE AND SIGNIFICANCE OF INTERNATIONAL TRANSFER OF TECHNOLOGY IN THE CONDITIONS OF DEVELOPING THE NATIONAL ECONOMY OF THE COUNTRY
Authors: Galaziuk Natalia , Zelinska Olha
Published: November 2024

The purpose of the article is to study the theoretical and practical aspects of the development of international technology transfer. It has been established that today the latest technologies and innovations affect all spheres of the national economy. Participation in the international transfer of technologies becomes a necessary and imperative condition for the existence of any production, not only at the state level, but also at the global level. That is why state support for innovative activities, namely the promotion of research and development, affects the socio-economic development of modern society.
The functioning and development of the world economic system takes place under the influence of the processes of integration and globalization, which leads to the acceleration of the movement of capital, financial and labor resources, goods and the growth of the intensity of information exchange. Due to the accumulation of scientific and technical potential in a number of economically developed countries, it is knowledge, intelligence and innovation that become the main driving force behind the success of individual companies in these countries in the global economy. Today, modern companies enter into a competitive struggle not so much for the level of development of the production structure and its volumes, as for the level of available innovations on the global technology market. Today, domestic science is on the brink of disaster, this state is explained by the economic crisis that occurred against the background of the military aggression of our northeastern "neighbor".
In Ukraine until 2022, there were negative processes associated with the development of scientific and technological developments, as evidenced by numerous studies of the dynamics of the share of R&D expenditures in GDP, it is obvious that in today's conditions this is an unacceptable trend and the state should make maximum efforts for practical and rapid accumulation of such a sector of the national economy as science.
It has been proven that Ukraine should focus on the specifics of the development of international legal regulation and guarantees in the field of technology transfer, from the point of view of international obligations. Since even those norms of international regulations implemented in domestic legislation do not provide full guarantees for the formation and development of a transparent and fair international technology transfer.
Por una descolonización de la Historia global
Authors: García Fernández Javier
Published: November 2024

Este ensayo examina las tensiones y diálogos entre la nueva historia global y los estudiosposcoloniales y decoloniales, destacando la persistencia del eurocentrismo en la historiografíacontemporánea. A través de un análisis crítico de las obras recientes de historiadores comoSebastian Conrad, Roca Barea y Bruce Gilley, se observa una reafirmación de narrativas eurocéntricas que minimizan la relevancia de las teorías críticas emergentes del sur global. Aunque algunos intentan articular un acercamiento entre la historia global y las teorías poscoloniales, estos trabajos a menudo carecen de un verdadero compromiso con las voces racializadas y migrantes. Además, se destaca la práctica del extractivismo epistemológico, donde conceptos críticos son apropiados sin el reconocimiento adecuado de sus orígenes. Para avanzar hacia una historiografía verdaderamente inclusiva, es esencial reconciliar las perspectivas globales con las teorías poscoloniales, fomentando un diálogo crítico que integre experiencias diversas. Este proceso implica reconocer la importancia de la descolonización dela historia y promover un entendimiento más matizado del pasado, que no solo refleje las narrativas eurocéntricas, sino que también incorpore las múltiples voces y experiencias que han configurado la historia mundial.
