Published: July 2024

Subject. This article examines the pension system of Russia in the period from 1990 to the present, the step-by-step process of its formation, development, reform, and accompanying problems.
Objectives. The article aims to periodize the process of pension reforming in post-Soviet Russia, describe the main stages, summarize the transformations, and assess the further prospects of the pension system.
Methods. For the study, we used comparative, statistical, analytical, and chronological methods.
Results. The article identifies the key stages in the development of the pension legislation of the Russian Federation and analyzes each of them from the standpoint of setting goals, their implementation and consequences, and the ensuing problems.
Conclusions. The decline in the pension replacement rate, the budget deficit of the Social Fund of Russia, the liquidation of the State-funded pension and the unclear prospects of the new long-term savings programme cast doubt on the sufficiency and effectiveness of the reforms carried out. In the future, compulsory pension insurance will develop towards a pay-as-you-go pension scheme. The funded component of the system will move to the sphere of non-State pension provision.
РЕЦЕПЦІЯ ДІЯЛЬНОСТІ СОЮЗУ УКРАЇНСЬКИХ АДВОКАТІВ НА ШПАЛЬТАХ ГАЗЕТИ “ДІЛО” (1923 – 1934)
Authors: КУРИЛИШИН Костянтин , ГАЛІВ Микола
Published: July 2024

Мета дослідження – з’ясувати особливості рецепції авторами та редакцією газети “Діло” діяльності СУА у 1923 – 1934 рр. Хронологічні рамки обумовленні тим, що саме у перше десятиліття діяльності СУА відбулося становлення основним форм і напрямів діяльності організації, що було відзначено під час ювілейного святкування 10-річчя СУА в 1934 р. Методологія дослідження спирається на принципи історизму, системності, об’єктивності, а також на методи критики історичних джерел, контент-аналізу пресових матеріалів. Наукова новизна. Уперше в історичній науці проаналізовано висвітлення діяльності Союзу українських адвокатів у Львові у перше десятиліття діяльності цієї організації у щодення українській газеті “Діло”. Висновки. Отже, Союз українських адвокатів упродовж першого десятиліття свого існування перетворився на розгалужену, структуровану громадську організацію українських адвокатів у Польщі (передовсім на Східній Галичині і Волині), яка об’єднувала у своїх лавах близько 75 % адвокатів-українців. Він був унікальною професійною спілкою на українських теренах у міжвоєнні роки, оскільки подібних організацій не існувало на інших українських землях у складі СРСР, Румунії і Чехословаччини. Зважаючи не нестачу архівних матеріалів до історії СУА, одним з найбільш повних і доступних історичних джерел залишається українська преса, зокрема щоденна газета “Діло”. У ній публікувалися статті, які містили факти (дати, події, імена і прізвища осіб) про загальні збори організації, її керівні органи, напрями діяльності тощо. Важливо, що у газеті висвітлювалися результати діяльності осередків СУА у провінційних містах Галичини (Стрию, Коломиї, Самборі, Станіславові, Дрогобичі, Тернополі), а також конспектувався зміст наукових та практично-інформаційних доповідей членів організації. Газета “Діло” детально інформувала читачів про один із найбільш важливих напрямів діяльності СУА – захист прав української мови в адміністративній та судовій системі міжвоєнної Польщі. Не меншу увагу газета приділила святкуванню 10-річного ювілею СУА, який відзначали у Львові 22 вересня 1934 р.

Published: July 2024

Financial management is the heart of a business. Many businesses fail and eventually go bankrupt due to poor financial management. Quality products and services with sound financial management will be helpful with thorough financial planning. Empowering MSMEs is one of the government's commitments. Universities have a role in helping the government in empowering MSMEs. Therefore, Andalas University has organized various programs to carry out this role. One of the programs organized by Andalas University is the Business Camp activity. Business Camp activities consist of several types of empowerment material, including MSME financial management. First Business Camp activities with Financial Management material were conducted online using the Zoom Meeting Application. The activity was held on Saturday, 28 October 2023. The main participants in this activity were MSME owners whom Andalas University accompanied. However, this activity did not close the opportunity for other MSMEs who want to join. Therefore, as many as 80 participants had taken part in this activity. The result of this activity was the motivation for MSMEs to separate their financial books first so that sound financial management can be carried out. This activity is essential to carry out so that MSME businesses can become businesses that continue to grow.

Published: July 2024

In modern society, monetary culture of students plays a significant role in the context of forming their competent financial behavior. The financial sphere is constantly changing and influencing money management, which makes it interesting to study money culture. Based on the existing studies of students' monetary culture, the author's sociological research aimed at studying the monetary culture of student youth was conducted. Students of the Financial University acted as the empirical object of the study. The subject of the study was the peculiarities of monetary culture of student youth. The purpose of the study is to identify the specific features of students' monetary culture. A questionnaire survey (n=434) was chosen for the sociological study. The scientific novelty of the research consists in conducting a study according to the author's methodology aimed at quantitative analysis of the characteristic features of monetary culture in the context of its structural components. The main result of the study can be considered the analysis of monetary culture in the context of its structural components: monetary knowledge, monetary values and monetary behavior. The main conclusion of the study was the identification of fragmented formation of students' monetary culture. The index of cognitive component formation was higher than the index of behavioral component formation. At the same time, a significant part of students has no demonstration of conscious, rational monetary practices and attitudes. Understanding the specifics of monetary culture allows us to analyze the problem areas of student youth in the field of financial management, in this regard, the practical significance of the research results, on the one hand, opens opportunities for further research, and on the other hand, acts as an information base for the creation and implementation of strategies and techniques to improve financial literacy of young people.

The author deals with the text of an archival document discovered in the materials of the Second Kamchatka expedition led by Vitus Bering, in the collection of field notes of the expedition member, the German doctor and translator G. W. Steller. This fragment in Latin is a recording of a Yakut folk song of the first half of the 18th century. The purpose of this article is to introduce a previously unpublished archival text into scientific circulation by translating the text and describing its artistic features. As part of the research, the following tasks were set: to study the history of the text, give a description of the manuscript, transcribe and translate it into Russian and highlight the artistic means used. According to the fixation of Yakut folklore in the specified period is known to science the ethnographic work of J. J. Lindenau “Description of the nations of Siberia,” which contains the text of the algys ritual on the Ysekh holiday. There are also recordings of folk songs of northern nations performed by G. W. Steller, but this text has not yet been examined by folklorists. The work uses theoretical and practical research methods as: study of scientific works, the main research method is textual analysis, which uses the method of review, description, interpretation, connection, translation, decoding and analysis of the composition, artistic and visual means of the text. The author concludes that the ancient folk song has a developed syllable. Rhythmic alliterative verse, consonance of line endings close to varieties of rhyme, parallel constructions, constant epithets and comparisons as the main means of depiction demonstrate a fairly high level of development of Yakut folk poetry. The author sees the prospect of research in the discovery of similar texts of the specified period, which would allow more in-depth research in this area.
A Thin Film Approach to Rapid, Quantitative Measurements of Mixed-Gas Adsorption Equilibrium in Nanoporous Materials

Published: July 2024

Nanoporous adsorbent materials are a key part of many industrial processes, including the rapidly-expanding carbon capture industry. Development of advanced sorbents requires an assessment of the sorbent’s performance under mixed-gas conditions. Existing measurement techniques tend to be slow, material-intensive, and have limited ability to measure competitive mixed-gas sorption. We have developed a novel technique that measures thin films of sorbents deposited onto sensitive micro-electromechanical system (MEMS) transducers. This technique is fast, requires very little material, and enables real-time monitoring of binary gas sorption. We report measurements of CO2/H2O mixed-gas isotherms at three different temperatures on the carbon capture MOF CALF-20. The measured experimental data on CO2/H2O mixture adsorption in CALF-20 demonstrate the severe limitations of the Ideal Adsorbed Solution Theory (IAST) in providing a quantitative estimation of the component loadings. Departures from the IAST are quantified by introduction of activity coefficients and use of the Real Adsorbed Solution Theory (RAST).
Asymmetric Syntheses of Aziridine-2-carboxylates via Reductive Kinetic Resolution of 2H-Azirines
Authors: Zheng Yinuo , Rizzo Antonio , Chiu Pauline
Published: July 2024

Enantioenriched aziridine-2-carboxylates are valuable organic compounds thanks to their versatility as chiral building blocks. Several syntheses of bioactive molecules employ aziridine-2-carboxylates as a crucial synthetic intermediate, e.g. the total synthesis of dynobacin A. However, traditional strategies only access N-protected aziridines, which are poorly stable and can undergo unwanted side reactions as ring-opening. Herein, we present the first copper hydride kinetic resolution of racemic 2H-azirines for the asymmetric preparation of N-H aziridine-2-carboxylates and the corresponding enantioenriched 2H-azirines. This is relevant as N-H aziridine-2-carboxylates are a generally bench stable and easily diversifiable building block. After an extensive catalyst screening and reaction optimization, the N-H aziridines were obtained with excellent diastereoselectivity (>20:1) and high enantioselectivity (up to 94%). Additionally, we conducted a Hammett study and we observed a linear free energy relationship between the ΔΔG⧧ of the diastereomeric transition states and the σp- values.
(Supra-)Molecular Capsules
Authors: Cox Cameron , Hale Jessica , Molinska Paulina , Lewis James
Published: July 2024

Stemming from early seminal notions of molecular recognition and encapsulation, three-dimensional, cavity-containing capsular compounds and assemblies have attracted intense interest due to the ability to modulate chemical and physical properties of species encapsulated within these confined spaces compared to bulk solution. With such a diverse range of covalent motifs and non-covalent (supramolecular) interactions available to assemble building blocks, an incredibly wide-range of capsular-type architectures have been developed. Furthermore, synthetic tunability of the internal environments gives chemists the opportunity to engineer systems for uses in sensing, sequestration, catalysis and transport of molecules, just to name a few. In this tutorial review, an overview is provided into the design principles, synthesis, characterisation, structural facets and properties of coordination cages, porous organic cages, supramolecular capsules and mechanically interlocked molecules. Using seminal and recent examples, the advantages and limitations of each system are explored, highlighting their application in various tasks and functions.
Modulating the Coordination Properties of 4-Coordinate Copper(I) Using Catenane Ligands Composed of Differently Sized Macrocycles

Published: July 2024

Upon coordination to catenane ligands derived from interlocked macrocycles of different size, gradual deviation of the coordination structure of the resulting 4-coordinate copper(I) complexes from the preferred tetrahedral geometry is resulted, and such structural distortion represents a new mechanism for modulating the thermodynamic, kinetic, photophysical and electrochemical properties of the transition metal complexes via ligand mechanical interlocking. Results from this study hence not only first demonstrate that the extend of catenand effect on metal coordination properties can be tuned by a physical attribute characteristic to mechanical interlocking, but also are implicated in the reactivity and potential applications of a distinct, rarely studied class of transition metal complexes supported by mechanically bonded ligands.
LoGAN: Local generative adversarial network for novel structure prediction
Authors: Kovács Péter , Heid Esther , De Landsheere Jasper , Madsen Georg K. H.
Published: July 2024

The efficient generation and filtering of candidate structures for new materials is becoming increasingly important as starting points for computational studies. In this work, we introduce an approach to Wasserstein generative adversarial networks for predicting unique crystal and molecular structures. Leveraging translation- and rotation-invariant atom-centered local descriptors addresses some of the major challenges faced by similar methods. Our models require only small sets of known structures as training data. Furthermore, the approach is able to generate both non-periodic and periodic structures based on local coordination. We showcase the data efficiency and versatility of the approach by recovering all stable C5H12O isomers using only 39 C4H10O and C6H14O training examples, as well as a few randomly selected known low-energy SiO2 crystal structures utilizing only 167 training examples of other SiO2 crystal structures. We also introduce a filtration technique to reduce the computational cost of subsequent characterization steps by selecting samples from unique basins on the potential energy surface, which allows to minimize the number of geometry relaxations needed after structure generation. The present method thus represents a new, versatile approach to generative modeling of crystal and molecular structures in the low-data regime, and is available as open-source.
SPCal - An open source, easy-to-use processing platform for ICP-TOFMS based single event data
Authors: Lockwood Thomas , Schlatt Lukas , Clases David
Published: July 2024

Single particle inductively coupled plasma – mass spectrometry (SP ICP-MS) has evolved into one of the most powerful techniques for the bottom-up characterisation of nanoparticle suspensions. The latest generations of time-of-flight mass analysers offer new perspectives on single particles by rapidly collecting full mass spectra and providing information on particle composition and abundances even in unknown samples. However, SP ICP-TOFMS is associated with vast data sizes with complex structure, which can hamper its applicability and the interrogation of specific particle features. Unlocking the full potential of SP ICP-TOFMS requires dedicated, easy-to-use software solutions to navigate through data sets and promote transparent, efficient and precise processing. SPCal is an open-source SP data processing platform, which we have previously released for quadrupole-based data. In this work, we expand its reach by enabling the analysis of TOF-based SP data sets additionally. We have incorporated various tools to facilitate the handling, manipulation and calibration of large data sets and provide the required statistical fundament and models to promote accurate thresholding. Non-target screening tools are integrated to pinpoint particulate elements in unknown samples without the requirement for a-priori investigations or modelling. Next to basic functions like the calibration of size and mass distributions, methods to carry out cluster analysis (PCA, HAC) provide the means to study groups of particles based on their composition and conditional data filtering allows the interrogation of particle populations by selectecting specific features.
Neural Network Energy Control of Combustion Engines for Automotive Software Applications
Authors: Carvalho Silva Marcos Henrique , Oliveira Maggio André Vinícius , Laganá Armando Antônio Maria , Filho João Francisco Justo , Silva Pereira Bruno , Moscardini Demerson
Published: July 2024

This article focuses on the application of neural network control for energy generation in an internal combustion engine. A two-layer neural network architecture was developed and tested using laboratory data obtained from a bench dynamometer to accurately identify the network’s parameters. The neural network is employed to establish an accurate correlation between the magnitude of actuation signals and the fundamental variables responsible for regulating energy generation within the system. The control system utilizes a gain-scheduling routine to adjust the controller’s gain, which attenuates the increment for low error values. An energy generation model is presented to design a virtual engine, enabling accurate control strategies. To ensure the safe operation of the engine, a safety routine is implemented to prevent the control action from assuming values that could negatively impact the vehicle’s response to the driver’s commands. The developed controller demonstrates a low average absolute error in steady-state conditions and a low average rise and fall time during transient states, ensuring both drivability and good engine performance. To enable the application in software, in structures such as hardware-in-the-loop simulation and engine control units, systems are implemented to ensure real-time operations.

Así, se buscó identificar las principales diferencias entre estos dos proyectos mnemónicos, situando la remodelación del espacio en un contexto de transformación de las memorias colectivas mexicanas respecto el movimiento estudiantil de 1968. En la parte final del artículo, también se analiza la relación dialógica que dichos espacios han establecido con su público visitante.

Museu Kanindé
Authors: Da Silva Santos Suzenalson
Published: July 2024

Nos últimos anos, o povo indígena Kanindé tem atuado na apropriação de um processo museológico, protagonizando a construção de  um museu,  um espaço de memória e centro de documentação em seu território onde este espaço tem  assumido um importante papel na luta e resistências do povo ao se constituírem em um potente espaço de reivindicação de uma educação diferenciada, de valorização dos processos tradicionais de transmissão de conhecimento, de afirmação étnica, de construção de autorrepresentação e contra narrativas, de produção, difusão cultural e de luta pela demarcação do território, produzindo um processo de autonomia. Atualmente o envolvimento do povo Kanindé nesse projeto de construção de um espaço específico que represente a sua cultura, tem sido em torno de uma consciência sobre a importância de se preservar seus ritos, saberes, fazeres e ecossistemas presentes em seu território. O presente trabalho pretende demonstrar as experiências que se entrelaçam diretamente aos processos museológicos próprios dos Kanindé em Aratuba no Ceará em busca do direito a uma memória indígena preservada.

Published: July 2024

O artigo é resultado de um estudo piloto qualitativo realizado com trabalhadores de hospitais públicos administrados por instituições privadas, cujo objetivo foi identificar e analisar os principais impactos do trabalho nessas instituições, conhecidas como Organizações Sociais de Saúde. A pesquisa foi realizada no Espírito Santo, Brasil, em 2019. Foram realizadas entrevistas individuais com trabalhadores que atuam em pelo menos uma das instituições participantes. A análise baseou-se nas técnicas da Grounded Theory, Teoria Fundamentada nos Dados, com codificação criteriosa e metodologia comparativa, resultando em quatro categorias empíricas: Admissão, Gestão de Pessoas, Gestão e Qualidade, Saúde e Qualidade de Vida. Os resultados mostraram que os profissionais de saúde são afetados de maneiras diferentes e contraditórias de acordo com a categoria e a formação profissional; há precariedade e problemas de qualidade que impactam negativamente tanto o trabalho, como os trabalhadores; há insatisfação, sobrecarga, adoecimento e perda de qualidade de vida.As principais conclusões apontaram para a necessidade de se instituir práticas e condições apropriadas na gestão do trabalho nas instituições, visando a melhoria na saúde do trabalhador e a qualidade na assistência à saúde da população.

O objetivo do estudo foi compreender as relações de trabalho dos(as) gerentes de atenção básica da capital Maceió, Alagoas. Trata-se de investigação com abordagem qualitativa, desenvolvido a partir de entrevistas semiestruturadas e com a técnica de análise de conteúdo. Foram identificadas quatro categorias de análise: lotação no cargo, necessidade de formação, jornada de trabalho e vencimentos. Os resultados indicaram que as relações de trabalho se mostram ainda muito frágeis, pois são regidas por contratos sem estabilidade do vínculo, que promovem sensação de insegurança com relação a emprego e renda. Identificamos que prevalece o modelo discricionário para provimento desses cargos, sem a publicização dos critérios para seleção e suscetível a influência de interesses político-partidários ou clientelistas, muitas vezes alheios aos objetivos de saúde. A ausência de critérios para seleção e de oferta de uma formação que prepare os(as) gerentes para a função diminui a qualidade do seu desempenho. A remuneração percebida pelo trabalho é insuficiente, gerando insatisfação dos(as) gerentes, que frequentemente a complementam com outras fontes de renda. Consideramos que esses resultados indicam dimensões da precarização do trabalho a que estão submetidos os(as) gerentes de atenção básica.
Subjetividade e hipervulnerabilidade no consumo de pessoas idosas

Published: July 2024

As relações de consumo envolvem os sujeitos em seus processoscotidianos, em uma dimensão social das experiências produtivas, atravessadas incessantemente pela subjetividade. O artigo objetiva discutir como pessoas idosas vivenciam suas dificuldades e restrições na sociedade capitalística de consumo, evidenciando aspectos de vulnerabilidade. Partindo do diálogo do conceito dehipervulnerabilidade no consumo, argumentamos sobre a insuficiência na estrutura intrínseca de justiça e equidade para que pessoas idosas participem das dinâmicas sociais, conforme os riscos de exclusões e as estigmatizações verificadas no consumo. Investimos em um estudo de tema livre, cuja reflexão envolveu campos conceituais e categorias com ênfase nas relações de consumo e de produção de subjetividades. Finalmente, indagamos como o envelhecimento é um processo afetado por tais relações na sociedade de consumo, tendo fatores complexos como ideais de jovialidade, mercado de trabalho, poder aquisitivo, aposentadoria e “ocupismo”, que interferem na produção de subjetividades, no consumo e nos modos de existência das pessoas idosas.
Redes insurgentes: como o movimento Black Lives Matter ajudou a reorganizar o sindicalismo estadunidense?
Authors: BRAGA RUY
Published: July 2024

A atual onda de agitação trabalhista nos Estados Unidos, evidenciadatanto pela criação de novos sindicatos em setores tradicionalmentedesorganizados, quanto pelo aumento do apetite grevista dos trabalhadores sindicalizados, foi seguida por um súbito aumento dos protestos em defesa das vidas negras, em escala global, em decorrência do assassinato, no dia 25 de maio de 2020, de George Floyd pela política de Minneapolis. Embora a literatura que tem analisado a globalização do movimento Black Lives Matter tenha negligenciado a relação entre a luta antirracista e a revitalização dos sindicatos, existem muitos indícios capazes de revelar a referida intersecção. Neste artigo, pretendemos analisar um caso específico que aponta para uma íntima conexão entre a luta pela justiça racial e a luta pela justiça econômica: a criação do Amazon Labor Union (ALU), o primeiro sindicato da empresa Amazon do país.
Modification Structure of Cinnamaldehyde with Primary Amines by Reflux and Sonication Methods in the Presence of Sulfuric Acid as a Catalyst

Published: July 2024

Cinnamon is one of the most valuable natural resources that sustains life and exists freely in nature. Cinnamaldehyde is the primary compound in cinnamon oil. It has a unique structure that contains a benzene ring, an aldehyde group, and an unsaturated double bond. Cinnamaldehyde has been structurally modified to improve biological activity. In this research, cinnamaldehyde and nitrophenyl amines were reacted with sulfuric acid as a catalyst by refluxing and sonication. UV-Vis Spectroscopy, FT-IR, 1H-NMR, and 13C-NMR were used to validate the chemical structures. Thin-layer chromatography (TLC) revealed a new single spot formed by the reaction of cinnamaldehyde and 4-amino-2-nitrophenol. By refluxing for 2 hours or sonicating for 30 minutes, a novel imine chemical, 4-nitro-2-((3-phenylallylidene)amino)phenol, was effectively synthesized with a yield of 75.21% or 83.71%, respectively. This imine was obtained as a dark red powder with a melting point of 237 °C. Meanwhile, only sonication produced a novel product from the reaction of cinnamaldehyde and 4-nitroaniline. However, the structural elucidation has not yet been performed because the yield was so low. Surprisingly, there was no reaction between cinnamaldehyde and 2,4-dinitroaniline. It was most likely owing to the amine’s bulky structure and the presence of two nitro groups in the amine as electron-withdrawing groups that reduced the nucleophilicity of the amine. We demonstrated that sonication is a suitable approach for imine synthesis, as it is commonly utilized in organic compound synthesis protocols.

Polyethylene terephthalate (PET) is utilized in the containment of potable water, nonetheless, it is susceptible to impairment due to temperature and duration of storage. Migration of formaldehyde from PET arises as a consequence of thermal deterioration. This study aims to ascertain the extent of formaldehyde transference in PET-contained drinking water of varying condition, subjected to diverse temperature setting and storage durations. An examination into the levels of formaldehyde migration in polyethylene terephthalate (PET) bottled drinking water was effectively carried out employing a validated high-performance liquid chromatography (HPLC) technique. A total of 162 water samples from three different PET bottled water brands sourced from supermarkets in Palu City, Central Sulawesi, Indonesia, underwent analysis. The formaldehyde assessment was executed utilizing a mobile phase composition of methanol:acetonitrile:water (48:12:40 v/v) for 12.97 minutes at a flow rate of 0.8 mL/minute on the 1st day, the 14th day, and the 42nd day while stored at room temperature and exposed to sunlight. Formaldehyde, lacking effective chromophoric entities and not readily ionizable, necessitated derivatization with 2,4-dinitrophenylhydrazine before HPLC analysis. The findings of the study demonstrated exceptional method linearity within the concentration span of 0.5 to 1321 µg/mL, exhibiting a commendable correlation coefficient of 0.999. The limit of detection (LOD) and quantification (LOQ) were determined to be 17.33 and 57.76 µg/mL, correspondingly. Precision evaluations displayed average intraday and interday values of 128.46±3.48% and 103.19±0.12%, respectively (%RSD < 2/3 CV Horwitz ratio). The intraday and interday %recovery values were computed at 97.22±3.48% and 96.83±0.14% (n = 6). The scrutiny of formaldehyde concentrations in the water samples unveiled the absence of formaldehyde migration.
