CARACTERIZACIÓN BIOQUÍMICA DE DOS TRÍMEROS DE LA PROTEÍNA DE LA DIVISIÓN CELULAR BACTERIANA (FtsZ) DE E. coli.
Authors: Alvarez Nelson Alexander Araujo , Veloso Marcelo , Pouchucq Luis
Published: January 2024

La FtsZ es una proteína del divisoma bacteriano responsable de la formación del anillo Z en la citocinesis. La caracterización de los oligómeros de la proteína FtsZ de Escherichia coli (EcFtsZ) en su estado nativo es un desafío porque la proteína se encuentra como un multioligómero en equilibrio de autoasociación-disociación. Nosotros caracterizamos el estado trimérico de la EcFtsZ a través de técnicas de PAGE nativo, cromatografía de filtración en gel y gradiente de sacarosa combinada con entrecruzamiento químico. Los resultados por filtración indican que el trímero de EcFtsZ tiene una masa molecular de 131 kDa y un coeficiente de fricción por filtración (Rs/Rmin) igual a 1.9, mientras que el coeficiente de fricción por filtración teórico (fn/f1) calculado para un trímero lineal arrojó un valor igual a 1.8 que está muy cercano al valor experimental. Por otro lado, la EcFtsZ entrecruzada con formaldehído presentó una banda de 128 kDa reconocida por anticuerpos anti-FtsZ y un coeficiente de fricción por sedimentación (Smax/S20,w) igual a 1.9, mientras que el coeficiente de fricción por sedimentación teórico (Sn/S1) calculado para un trímero triangular resultó igual a valor experimental. Estos resultados sugieren que la EcFtsZ tiene dos estructuras homotriméricas (lineal y triangular). Finalmente, reportamos la agregación de la EcFtsZ a concentraciones micromolares de Capsaicina sin GTP y Mg2+.
WHAT DO STEM CLUBS DO? THE EFFECT OF COLLEGE CLUB PARTICIPATION ON CAREER CONFIDENCE AND MODERN SEXISM
Authors: Dominguez Guillermo , Glass Jennifer
Published: January 2024

Literature on STEM's "chilly climate" shows that minoritized students attrite from the STEM labor force faster than White and Asian men following graduation. Demand side theories posit that this lack of diversity is the result of unwelcoming work environments relative to opportunities outside of STEM, while supply side theories argue that women in particular lack confidence to persist in STEM
coursework and in the STEM labor force. We hold that educational experiences help shape both who pursues a STEM career and what ensuing climate difficulties persist in STEM work settings. We show that STEM college clubs are important sites of cultural capital development associated with students' attitudes toward women's inclusion in the STEM workforce. Using data from two large U.S. universities, we find that student involvement in honorific clubs, where membership is based on achievement, and affinity clubs, where membership is based on common identities or interests, are associated with a decrease in sexist attitudes for most groups. Our intersectional analysis, however, reveals that the association between club involvement and sexist attitudes differs by the type of club, and by respondents' race, gender, and field of study, revealing subgroups of men for whom club involvement is associated with increased levels of hostile sexism. We find that club involvement has no effect on members' confidence in crafting a successful career and thus does not at present reduce gender disparities in career confidence. This research suggests closer scrutiny of the "hidden curriculum" of extracurricular STEM activities.
Removal of phenoxy acid herbicide from water by magnetic mesoporous silicate
Authors: Al-Mahfuz Al-Hussein Imad Attwan , Ghaemi Arezoo
Published: January 2024

Superparamagnetic iron (II,III) oxide (Fe3O4)–MCM-41 was successfully synthesised using a direct hydrothermal route and was utilised as an excellent adsorbent for the removal of the herbicide 2,4-dichlorophenoxyacetic acid from aqueous solution. The superparamagnetic mesoporous adsorbent was fully characterised using X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, nitrogen (N2) sorption and vibrating-sample magnetometry (VSM). The synthesised adsorbent exhibited a high specific surface area of 444 m2/g, making it a suitable candidate for adsorption, where it provided a higher adsorption capacity. Based on the VSM study, the recorded saturated magnetisation was 15.9 emu/g, which confirmed the viability of easily separating the adsorbent from an aqueous medium using a magnet. The ability of iron (II,III) oxide–MCM-41 to adsorb the herbicide 2,4-dichlorophenoxyacetic acid from water was tested considering various parameters, such as pH, adsorbent dosage, contact time and pollutant concentration. The effectiveness of iron (II,III) oxide–MCM-41 in removing the herbicide reached its highest peak at pH = 5, 0.05 g adsorbent, 60 min contact time and 10 mg/l 2,4-dichlorophenoxyacetic acid. The maximum removal efficiency under optimum conditions was 94.8%. Based on the experimental data and kinetic studies, the adsorption process followed a pseudo-second-order kinetic and Langmuir isotherm model.
DIREITOS HUMANOS, O RECONHECIMENTO DO VALOR DA PESSOA; A CONTRIBUIÇÃO DE MIGUEL REALE
Authors: de Carvalho José Mauricio , da Silva Andrade Izadora Caroline , das Chagas Junio da Silva
Published: January 2024

In the last century, human dignity became a principle recognized in the Constitution of different States and in international treaties, after the promulgation of the Universal Declaration of Human Rights (1948), reinforced by the International Covenant on Economic, Social and Cultural Rights ( ICESCR) (1976). These facts gave relevance to the theme and drew attention to the emergence, implications and foundation of human rights. The problem examined in this article is the contribution of Miguel Reale's legal theory to these questions. Reale's three-dimensional philosophy of Law is juxtaposed to the recognition that the construction of human rights is a historical process initiated in ancient Rome. This process gained consistency with studies of the person during the Middle Ages. At that time, there was still a hierarchical view of dignity, which came from ancient Rome and lasted until the emergence of the liberal state. If dignity initially depended on the status or position of the individual, it gradually extended to all men. Reale's theory explains how this process took place, having as a background the characterization of values ​​as a cultural object of its own, with a historical character. In this axiology, the human person is the most important value and source of all others, just what the UN document recognizes.
A BIOPIRATARIA NO CONTEXTO DA LEGISLAÇÃO DA BIODIVERSIDADE
Authors: Figueroa Ricardo Gomes , Guimarães Raissa De Luca , Carvalho Azevedo Vasco Ariston de
Published: January 2024

Biodiversity is a heritage of high economic value and capable of moving several sectors of the economy. Brazil is a signatory to the Convention on Biodiversity - CBD - and in compliance with its obligations assumed under the Convention, Law 13123/2015 was approved, which provides for access to genetic heritage, protection and access to associated traditional knowledge, as well as sharing benefits for conservation and sustainable use of biodiversity. Brazil ratified the Nagoya Protocol and took an important step towards the international fight in defense of its genetic heritage. Biopiracy is the misappropriation of a country's genetic heritage and traditional knowledge and has long threatened the entire genetic heritage protection structure. With little discussion among the main players in the innovation system, academia, government and industry, Law No. 13,123 was intended to promote the protection of this Brazilian heritage, but it has failed in this regard. It is characterized that divergences only corroborate the idea that the law of biodiversity was built without due and necessary caution and that it does not reflect the desired effect of the standard, economic, scientific and social development. In this sense, the purpose of this article is to analyze biopiracy as an obstacle to concepts and compliance with the requirements of biodiversity legislation and the impact it causes on the development of innovation, R&D, notably in the biotechnological area. The methodology used is descriptive and exploratory research, based on primary sources, legislation, literature and historical analysis. The balanced and equal construction of public policies should be the main focus of the actors involved in the implementation of this legal framework for biodiversity.
ÂMBITO DE PROTEÇÃO E DEPENDÊNCIA ENTRE DIREITOS DE PATENTE
Authors: REMÉDIO MARQUES JOÃO PAULO F
Published: January 2024

Based on European doctrine and the Author's previous work, the present work intends to illuminate the judicatively complex question of what are the requirements or assumptions whose verification make a invention patented (and therefore a technical solution provided with inventive activity and novelty in relation to the state of the art) “mysteriously” dependent on another previously patented invention, allowing the holder of the latter (dominant patent) to prevent the commercial exploitation of the first (dependent patent) - a situation that is susceptible of being released by entering into a voluntary license agreement or by granting a compulsory license. Basically, taking into account the Portuguese Industrial Property Code, European doctrine and jurisprudence and the European Patent Convention, we seek to demonstrate that the solution to these issues lies in the delimitation of the concrete (technological) scope of patent protection previously registered.
The Effects of Credit Score Migration on Subprime Auto Loan and Credit Card Delinquencies
Authors: Driscoll John C. , Flagg Jessica N. , Katcher Bradley , Sommer Kamila
Published: January 2024

In the early stages of the pandemic, income support and forbearance programs led consumer loan delinquency rates to fall to near-record lows for borrowers across the credit score distribution. Since the second half of 2021, however, delinquency rates have risen, and by 2023:Q3, overall rates for auto and credit card loans had risen above their pre-pandemic levels.
Die Bybel, die Christelike geloof en die natuurwetenskappe
Authors: Spangenberg I
Published: January 2024

In hierdie artikel word die kwaliteit beoordeel van die navorsing wat in die vier artikels, gepubliseer onder die tema "Geloof en Wetenskap" in die Tydskrif vir Geesteswetenskappe, 63(2):192-261 tot uitdrukking kom. As vertrekpunt dien die oortuiging dat alle standpunte en menings rasioneel en krities beoordeel moet word om die feitelikheid, oftewel waarheidsgehalte daarvan te bepaal. In die ondersoek word die wetenskaplike navorsingsproses in ag geneem en die standpunt verdedig dat natuurwetenskaplike en geesteswetenskaplike navorsing nie wesenlik van mekaar verskil nie. Dit wys die standpunt van die navorsers af dat geesteswetenskaplike navorsing vanuit bepaalde geloofsvoorveronderstellings gedoen mag word. Daar word verder geargumenteer dat waarheid en geskiedenis ten nouste met mekaar saamhang, want wat in een eeu waar mag wees, kan in 'n volgende eeu as onwaar bewys word; daarom is 'n historiese bewussyn van die allergrootste belang. Die gebrek aan 'n sodanige bewussyn kan navorsers duur te staan kom, omdat hulle uitsprake kan maak en standpunte kan inneem wat histories nie korrek is nie. Die navorsers van die onderhawige artikels se poging om te bewys dat Genesis 1-3 met die moderne natuurwetenskaplike resultate versoen kan word, is onoortuigend, omdat hulle nie die historiese en kulturele kontekste van dáárdie verhale in ag neem nie. Voorts lees die navorsers hul oortuigings in die tekste in en laat sodoende die Bybel buikspreek.
Versoening in die Afrikaanse gemeenskap: Tower-staf of keuse?
Authors: Carstens W
Published: January 2024

Versoening as term word maklik gebruik, maar mense verstaan nie altyd wat dit inhou nie. Juis omdat versoening die resultaat van 'n besondere proses is, is dit nodig om tog te begryp wat dit inhou indien 'n mens betrokke wou raak by so 'n proses. In hierdie oorsigartikel word dit kortliks gedoen en dan toegelig met die agtergrond tot die totstandkoming van die Afrikaanse Taalraad, 'n liggaam wat in 2008 gestig is na afloop van 'n versoeningsproses in die Afrikaanse taalgemeenskap. Versoening behels te alle tye 'n bestuurde proses wat tot 'n produk moet lei.
(Self)portrette in Uit die kroes deur Lynthia Julius: 'n Kultuurhandhawende pedagogiese benadering tot Afrikaanse literatuuronderrig
Authors: Basson E , Burger B
Published: January 2024

Histories is die onderrig van Afrikaanse literatuur op skoolvlak Afrikanergesentreerd. Alhoewel daar sedert die politieke omwenteling in 1994 in Suid-Afrika pogings aangewend is om 'n inklusiewer letterkunde voor te skryf, oefen die voormelde geskiedenis steeds 'n invloed uit op hoe Afrikaans op skoolvlak onderrig word. Ondanks die skoolkurrikulum se transformatiewe beginsels en verbintenis tot sosiale regstelling, word min tekste voorgeskryf wat nie in 'n standaardvariëteit geskryf is nie. Voorts maak die pedagogiese benadering tot letterkundeonder-rig wat taalonderwysers volg min ruimte vir uiteenlopende interpretasies van literêre tekste. Gevolglik skep dit 'n gaping tussen die beginsels van die skoolkurrikulum en dit wat in die letterkundeklaskamer gebeur. Paris en Alim (2017) se "kultuurhandhawende pedagogie" (KHP) is 'n onderrigbenadering wat die onderhou en ontwikkeling van leerders se kulture sien as sentraal tot pedagogiek. Ons voer aan dat 'n KHP-benadering gepas is vir die onderrig van Afrikaanse literatuur, aangesien dit sal behels dat leerders se variëteite en kultuurpraktyke nie gesien word as buite of slegs aanvullend tot die pedagogiese projek nie, maar eerder sentraal daartoe staan. In hierdie artikel fokus ons op hoe twee gedigte ("Ouma Xhau" en "Ontheemding") in Lynthia Julius se bundel Uit die kroes (2020) op 'n KHP-wyse onderrig kan word op 'n manier wat leerders in staat stel om Oranjerivierafrikaans, die invloed van Nama op Afrikaans, orale literêre tradisies en kulturele ontheemding te verken. Ons analise sluit praktiese raad in oor hoe hierdie twee gedigte onderskeidelik benader kan word as 'n tipe portret en selfportret om sodoende die Europese portretkunstradisie en die uitdaag daarvan in die klaskamer te verken.
The Development of Christian Care Aid in Zimbabwe: The Case of Matabeleland Region, 1967-c.1990
Authors: Takuva Tinashe
Published: January 2024

The organisation, Christian Care, was formed during Zimbabwe's liberation war in 1967 to disburse emergency aid to victims of the war and political repression. From 1967 to about 1990, it provided emergency relief and charity aid to victims of war and the marginalised people in Zimbabwe. This article explores the development of Christian Care aid from its inception to around 1990, tracing the changes over time. It shows how Christian Care managed to respond to the situation on the ground even when such an agenda was not in line with what the government of the day practised. Between 1967 and 1980, Christian Care's aid was largely emergency based, assisting war victims with food, clothes and money. After 1980, the nature and composition of aid changed to development projects such as drilling of boreholes, construction of schools, clinics and dams and assisting communities to set up income generating projects like market gardens. Using a qualitative research methodology with predominantly archival sources, I explore the development of Christian Care aid in the Matabeleland region of Zimbabwe, demonstrating how the organisation provided assistance to the repressed and marginalised.
The Catholic Church's Dialogical Method and Engagement with the Zimbabwean State between 2000 and 2010
Authors: Phiri Stephen
Published: January 2024

The Catholic Church's advocacy against bad governance in Zimbabwe (the country's name was Rhodesia till April 18, 1980) can be traced back to its colonial days. The nature of the Catholic Church's participation in the struggle towards good governance is focused on ensuring that the needs of the people are catered for by the responsible governmental structures. As the Catholic Church defends the people's rights, such a defense inevitably forces it to confront and challenge structures responsible for bad governance. Such confrontation or challenge of political or social structures (which it deems responsible for bad governance) is dialogical in nature as the Catholic Church expects a response towards their anticipated change. This article examines the nature of the Catholic Church's dialogical method by using an 'Empathetic Dialogical Method' focusing specifically on three Catholic Bishops' pastoral letters which were written between 2000 and 2010. A critical reflection of these letters reveals the contribution made by the Catholic Church during the post-independence period. In terms of dialogue, the article reveals that the Catholic Church's dialogical method is predominantly non-empathetic. It further understands the dialogical method of the Catholic Church as highly prescriptive and in most cases non-consultative. This position, as the article argues, is influenced by the Catholic Church's religious and political structure.

Produtividade de diferentes cultivares de sorgo em cultivos distintos e sob estresses térmico e salino em região semiárida
Authors: Andrade Mateus Ferreira , Siqueira Tânia da Silva , França José Geraldo Eugênio de , Simplício Josimar Bento , Tabosa José Nildo
Published: January 2024

A proposta de se trabalhar com a cultura do sorgo em solo de vazante no semiárido pernambucano, onde normalmente, existe a presença de sal tanto no solo quanto na água, em função das características da rocha matriz e materiais das enxurradas, teve como premissa aproveitar essas áreas que, se bem manejadas, são potencialmente agricultáveis possibilitando o cultivo de plantas que se adaptam bem a esse tipo de ambiente. Por apresentar sistema radicular “agressivo” e certa tolerância à salinidade, o sorgo pode explorar camadas mais profundas do solo em busca de água e nutrientes e apresentar produtividades surpreendentes. Por possuir também cutina protetora do colmo e da superfície foliar, resulta em menor perda de água por transpiração. Tais fatores permitem maior adaptação às adversidades desse ambiente, a exemplo de TºC superiores a 40ºC, estresses hídricos e salino e mesmo assim, têm apresentado produtividades satisfatórias quando comparado a outras Poaceae. O objetivo deste estudo foi avaliar 12 cultivares de sorgo forrageiro com características agronômicas distintas, sob irrigação com água de até 1.4 dS.m-1 proveniente do açude do saco, durante dois ciclos sucessivos, caracterizando a sazonalidade da primavera e verão, respectivamente, de 2015 e 2016. O experimento foi conduzido na área experimental do IPA, Serra Talhada – PE. O delineamento utilizado foi em blocos casualizados em esquema fatorial 2x12, o primeiro fator corresponde a dois sistemas de cultivos (com e sem cobertura morta (C/C e S/C) e o segundo, 12 cultivares de sorgo presentes na tabela 1. Sendo 22 tratamentos com 2 repetições, totalizando 44 unidades experimentais. Cada parcela foi formada por 3 fileiras de 5 metros de comprimento, espaçadas de 0,80m. A densidade de plantio após o desbaste foi de 15 plantas por metro linear. Ao final do experimento constatou-se que o sistema de cultivo com cobertura (C/C) possibilitou melhor produtividade de até 30% no 1º ciclo e de até 64% no 2º ciclo entre os sistemas estudados; o 2º ciclo foi favorecido pelas precipitações que proporcionaram produtividades entre 68,85 e 61,6 t.ha-1 de matéria verde - MV e entre 24,10 e 21,56 t.ha-1 de matéria seca - MS, respectivamente, nas duas condições de cultivo com cobertura - C/C e sem cobertura - S/C; as variedades IPA SF 15 e BRS Ponta Negra foram  superiores em  produtividade, com 120 e 100 t.ha-1 MV (C/C) e de 28 e 31 t.ha-1 MS (S/C), respectivamente no 1º e 2º ciclo, o sistema de cultivo S/C proporcionou maiores produtividades para as variedades SF17, 2502 e SF190, respectivamente.
Análise da Previsão das Mudanças Climáticas e seus Impactos em Sistemas Fotovoltaicos
Authors: Jurinic Francesco , Farret Felix Alberto
Published: January 2024

Planos audaciosos estão sendo implementados em todo o mundo para mitigar as mudanças climáticas. Tais planos exigem aumentos significativos da inclusão das energias renováveis e limpas acarretando sistemas mais vulneráveis, pois estes também são mais impactados pelas mudanças climáticas. Com esta visão, este artigo busca prever o grau com que os efeitos climáticos futuros poderão afetar os sistemas fotovoltaicos (PV) residenciais. Pela sua vasta área territorial, tomou-se como referência dados do Brasil para as condições dos sistemas fotovoltaicos residenciais o que representa um total de 818.149 instalações, que representam 78 % de todas instalações fotovoltaicas brasileiras (comercial, rural, industrial, residencial...). Para isto, este artigo propõe um método simples e preciso que pode ser facilmente expandido a nível mundial como contribuição para análises de cenários mundiais PV futuros. Analisou-se o desempenho das instalações existentes no país ao longo dos últimos 59 anos usando dados meteorológicos do período 1961 - 2020 com os quais foram projetadas previsões de climas futuros para até 100 anos. Constatou-se nos resultados destas previsões que todos os estados brasileiros já sofrem grandes perdas de eficiência devido à alta temperatura ambiental as quais estão aumentando gradativamente ainda mais, ano após ano, podendo chegar a um máximo aumento médio anual de mais de 5 ºC nos estados do norte-nordeste do país. Mesmo com estas perspectivas de redução no rendimento da geração elétrica PV é pouco provável que tais alterações climáticas venham a ameaçar esse setor no Brasil, pois com tudo isto ainda permanece um forte potencial de utilização.
Contradições entre a salvaguarda da natureza e as representações sociais da Unidade de Conservação Parque dos Manguezais (Recife-PE) através do prisma da ZEIS Ilha do Destino.

Published: January 2024

A discussão aqui apresentada se propõe a imergir na questão das áreas protegidas em território urbano. Estes enclaves ecológicos, geograficamente delimitados por instrumentos e legislação específica, surgem a partir dos esforços de salvaguarda daquilo que se compreende como natureza e recursos naturais. Contudo, os embates socioambientais emergentes das limitações de uso e acesso para comunidades correlacionadas, levantam o questionamento sobre até que ponto a política de criação de áreas protegidas logra êxito em seus objetivos de proteção da natureza. Analisam-se nesse texto as dissonâncias das relações homem-natureza entre a comunidade Ilha do Destino e a UCN Parque dos Manguezais, na cidade do Recife. Por meio da compreensão das representações sociais elaboradas por moradores locais sobre a UCN, buscou-se elucida quais são as principais forças que engendram as ações conflituosas entre essa comunidade e o ecossistema de manguezal. Com esta reflexão e discussão, entendeu-se que a salvaguarda da natureza na cidade, tradicionalmente convencionada, está mais aliada aos processos de gestão e manejo que levam em conta as representações sociais elaboradas sobre o território do que com a delimitação de recortes geográficos apartados da dinâmica socioambiental urbana.

“¿Quién puede entender esto sino como una perversidad del sistema?”: un análisis de la discusión sobre la implementación de la prisión preventiva en casos de lesa humanidad (Argentina 2003- 2015).
Authors: Quaretti Lucía
Published: January 2024

Este artículo reflexiona sobre el debate jurídico-político que tuvo lugar en Argentina en torno a la implementación de la prisión preventiva en casos de crímenes de lesa humanidad. Para abordarlo analiza una serie de fuentes escritas que constituyeron pronunciamientos públicos presidenciales, legislativos, jurídicos y de los Organismos de Derechos Humanos ⎯es decir, de los principales actores políticos que intervinieron en la discusión que nos interesa⎯ entre 2003 y 2015. Asimismo, se sirve de las estadísticas confeccionadas por el Sistema Penitenciario Federal y la Procuración de Crímenes Contra la Humanidad. Se concluye que el mencionado debate estuvo atravesado por dos tensiones principales. La primera se vinculó con las dificultades para sostener el principio de igualdad ante la ley. La segunda con las demoras y dilaciones que atravesó el proceso de juzgamiento de los criminales de Estado desde la reapertura de los juicios. Estos dos elementos condensaron las discusiones sobre la implementación del encierro preventivo en casos de violaciones a los Derechos Humanos.
Citizen Participation, Digital Agency, and Urban Development
Authors: Tappert Simone , Mehan Asma , Tuominen Pekka , Varga Zsuzsanna
Published: January 2024

Today’s exponential advancement of information and communication technologies is reconfiguring participatory urban development practices. The use of digital technology implies new forms of decentralised governance, collaborative knowledge production, and social activism. The digital transformation has the potential to overcome shortcomings in citizen participation, make participatory processes more deliberative, and enable collaborative approaches for making cities. While digital tools such as digital mapping, e-participation platforms, location-based games, and social media offer new opportunities for the various actors and may act as a catalyst for renegotiating urban space and collective goods, digitalisation can also perpetuate or even attenuate existing inequalities and exclusion. This editorial introduces the thematic issue “Citizen Participation, Digital Agency, and Urban Development” which focuses on the trajectories and (dis)continuities of citizen participation through digitalisation and elaborates this with examples from Europe and Asia on how the digital transformation impacts, challenges, or reproduces hegemonic power relations in urban development.
An Efficient Variant of Ranked Set Sampling, Probability Proportional to Size with Application to Economic Data
Authors: Amiri Saeid , Hassani Hossein , Heravi Saeed
Published: January 2024

In this paper, we apply the Ranked Set Sampling (RSS) technique to economic data in the form of homescan market research data set for the meat food group. The RSS method is then extended to select sampling units based on the Probability-Proportional-to-Size (PPS) approach. The new proposed ranked set sampling, using the PPS-derived method, RPPS, is assessed via Monte Carlo investigations and an extensive homescan data set to evaluate its performances. The results are promising and in line with theoretical and simulation studies, showing that the RPPS technique is more reliable and has a smaller variance than the PPS route.

Published: January 2024

BACKGROUND: One of the possible ways to improve the quality of dental treatment with obliterated root canals is the use of transcanal direct current exposure.
AIM: The aim of the study was to investigate the comparative antibacterial activity of anodic dissolution of copper and silver-copper electrodes used in the endodontic treatment of teeth in the experiment.
MATERIALS AND METHODS: An experimental study was performed by implementing a technique for the automatic cultivation of microorganisms in liquid culture media. We used for the study clinical isolates of individual strains of bacteria and yeasts, namely: S. constellatus, P. intermedia, C. albicans, as well as mixed cultures: 1) S. constellatus + F. nucleatum; 2) Streptococcus sanguis + Enterococcus faecium obtained from the root canals of the teeth during treatment of chronic pulpitis.
RESULTS: The results of the study showed that anodic dissolution of both silver-copper and copper electrodes had a significant and, in general, unidirectional antibacterial effect. At the same time, it was found that, if for clinical isolate of P. intermedia the use of a silver-copper electrode was more effective, then for S. constellatus and C. Albicans strains, as well as for mixed cultures of pathogenic microorganisms S. constellatus + F. nucleatum and Streptococcus sanguis + Enterococcus faecium anodic dissolution of a copper electrode showed a more pronounced antibacterial effect.
CONCLUSION: In endodontic treatment of teeth with partially obliterated root canals, along with anodic dissolution of silver-copper electrodes, it is possible to use anodic dissolution of copper electrodes as a means capable of having a pronounced antibacterial effect.
PLATFORM WORK IN SELECTED COUNTRIES OF EASTERN AND CENTRAL EUROPE
Authors:   University of Dubrovnik, Department of Economics and Business, Vojinić Perica , Bečić Marija
Published: January 2024

Labour markets are increasingly being organized through digital platforms. These platforms are often characterized by a systematic asymmetry of information and power in favour of platform providers. They rely on an independent workforce that receives low wages and no social security, and at the same time works for its own account and bears the risk independently. Non-standard form of business via digital platforms offers benefits such as more flexible working hours, more favourable prices, and opportunities for income generation, but it also come with challenges related to job stability, benefits, and legal protections. Since there are no official statistics on the size of platform work, a small number of literature deals with the research of the determinants of platform work. The aim of this paper is to determine how factors such as Internet purchases by individuals, GDP per capita, unemployment rate and DESI index affect the size of the platform work. The analysis was conducted on a sample of selected countries of Eastern and Central Europe (CEEC – Bulgaria, Czech Republic, Hungary, Slovakia, Romania and Estonia) and for this purpose Eurostat and ETUI Internet and Platform Work Survey data were used. The results of analysis show that the GDP per capita and Internet purchases by individuals influence the size of platform work in selected countries.
BABY BOOMERS AND GENERATION Z: THE ROLE OF CONSUMER ETHNOCENTRISM ON PURCHASE INTENTION
Authors:   University of Dubrovnik, Department of Economics and Business, Croatia, Pavlić Ivana
Published: January 2024

Ethnocentrism is a very sophisticated and complex phenomenon that attracts the attention of many scholars who study it from different angles. One specific approach, undoubtedly from the perspective of behavioural economics, is consumer ethnocentrism. Consumer ethnocentrism as a special phenomenon was created to study the link between marketing and consumer behaviour with the concept of ethnocentrism. This concept has been shown to have a greater impact on purchase intent than some traditional marketing approaches. Ethnocentrism has a significant impact on consumer attitudes towards foreign brands, purchase intentions and purchase decisions for products from Croatia and abroad. The main purpose of this paper is therefore to investigate the relationship between the ethnocentrism of different generations (Baby Boomers and Generation Z) and their purchase intention for domestic and foreign products. The survey was conducted using a questionnaire. 218 members of Generation Z and 223 members of Baby Boomers in the Republic of Croatia were included in the survey. The results showed that the high level of ethnocentrism among baby boomers is positively associated with the intention to purchase domestic products and negatively associated with the baby boomers’ intention to purchase foreign products from China and the former Yugoslavia. In addition, the likelihood of buying domestic products is higher where the level of ethnocentrism is higher. There is no correlation between the ethnocentrism of Generation Z and purchase intentions in general.

Actualmente España se encuentra en una fase de desarrollo activo del hidrógeno, y ha apostado por la producción, distribución y aplicación de hidrógeno verde como parte de su estrategia de transición energética. En nuestro día a día, vemos cómo el país avanza en inversión en I+D+i, en infraestructuras y en colaboraciones internacionales queriendo consolidar a España como un actor destacado. En el presente artículo se lleva a cabo un análisis del entorno del hidrógeno (análisis PEST) abarcando desde las políticas existentes hasta los diferentes retos económicos, técnicos y de aceptación social a los que se enfrenta el hidrógeno para su amplio despliegue. Este análisis PEST se aplica a lo largo del artículo a cuatro bloques temáticos: (1) producción; (2) transporte y distribución; (3) almacenamiento y (4) aplicaciones, con un enfoque bidimensional o matricial que permite una comprensión integral de los desafíos que el hidrógeno afronta en el panorama actual. Como conclusión, cabe decir que existe un entorno claramente favorable. Sin embargo, el hidrógeno verde aún no ha logrado un avance significativo, tanto por sus costes comparativamente altos con respecto al hidrógeno gris como por las pérdidas de eficiencia. Además el hidrógeno es difícil de almacenar y transportar, requiriéndose métodos como la compresión, la licuefacción o la conversión química en sustancias, todos ellos en desarrollo en un mayor o menor grado. No obstante, se destaca el inmenso potencial del hidrógeno como materia prima, siendo esto ya conocido. A esto se añade el nuevo camino que, junto con el CO2 capturado, se le abre para la producción de combustibles sintéticos o de e-fuels.

Artificial intelligence (AI) in dentistry is poised to alter a number of aspects of the industry, marking a paradigm shift of profound significance. Dental diagnostic procedures are being streamlined and optimized with the use of artificial intelligence technologies. Machine learning algorithms have demonstrated exceptional competence in the early identification of dental disorders, including cavities, periodontal diseases, and structural abnormalities in teeth, thanks to their extensive training on large datasets of dental pictures. These developments make it easier to intervene quickly, which enhances patient outcomes and lessens the strain on healthcare systems.

Furthermore, tailored care and AI-driven treatment planning have become important areas of innovation. AI algorithms assist in the creation of customized treatment plans by analysing patient data, including genetic predispositions and medical histories. The application of AI extends beyond diagnostics and treatment planning to optimize administrative tasks within dental practices. Automated appointment scheduling, billing processes, and electronic health record management systems powered by AI technologies contribute to increased operational efficiency, allowing dental professionals to focus more on patient care.

Combining human knowledge with AI skills has the potential to completely change the dental care industry by offering more precise diagnosis, individualized treatment plans, and enhanced patient experiences all around. As AI develops, its application to dentistry serves as a shining example of advancement, bringing about a new era in oral healthcare marked by increased accessibility, efficiency, and precision.
The archetypal approach and the formation of national identity: advertising, cinema, civilizational projects
Authors: Sokolova Marianna
Published: January 2024

The article analyzes the use of archetypal marketing technologies in business branding and their impact on the formation of national identity in the context of deglobalization. The conceptual approaches of American and Russian marketers to the use of the archetypal approach in commercial and political branding are discussed. The promotion of national brands, comic books, movies, and video games created on the basis of images of Russian folklore heroes yet styled as American superheroes, in the Russian cultural and symbolic space is considered. The article identifies manipulative risks and contradictions when using the archetypal approach in business branding and when creating Russian civilizational projects.
The present-day condition and prospects for development of the AUKUS program
Authors: Terebov Oleg
Published: January 2024

The article defines AUKUS as a strategic military-political, military-technological and military-economic program. It is argued that the program, because of its scale and multi-year term of implementation, will not be able to provide a decisive impact on the power balance in the Pacific. However, the USA ruling class will proceed with the AUKUS realization – as far as it views China as its global opponent, especially in the Indo-Pacific region. AUKUS is not a direct and substantially new threat for Russia, if it succeeds in independent, without reliance on any ally, maintain the numerical strength and high technological level of its own nuclear submarine fleet.
Canadian investments in Russia in 2014–2023
Authors: Khoroshilov Evgeny
Published: January 2024

The article examines investment flows between Russia and Canada in 2014–2023. The analysis of the activities of Canadian multinational companies in the Russian Federation under the conditions of the economic war declared by the United States and its allies to Russia is carried out. It is indicated that until 2022, Canadian capital in Russia was concentrated in such industries as mining, vehicle engineering, agriculture and food industry, retail trade and services. It is shown that to date, almost all Canadian TNCs that owned business in Russia have withdrawn from their Russian assets. The exception were two corporations operating in the service sector. It is concluded that the damage caused to the Russian economy by the departure of Canadian investors seems insignificant, since most of their enterprises have passed into new hands and continue to operate. It is estimated that the balance sheet loss on direct investments recognized by TNCs and institutional investors from Canada in connection with the withdrawal from the Russian Federation amounted to about USD 1,3 billion.
Data governance: proposal for a conceptual framework for Brazilian public administration
Authors: Caneparo dos Anjos Priscila
Published: January 2024

Data Governance (DG) has become a topic of outstanding importance in modern organizations, since the amount and complexity of data generated and stored has increased exponentially in recent decades. In this context, an effective GD becomes essential to guarantee the quality, reliability and security of information. This dissertation, through a literature review and research methodologies: content analysis and document analysis, identified 55 DG mechanisms in the literature review and sought evidence of their application in a sample of Government Constitutive Acts. For the selection of the sample, a survey was carried out on the World Wide Web in January 2023, where 12 documents were selected, 5 Normative Acts establishing policies and GD committees. As main results, it was possible to identify 167 GD mechanisms in the governmental context, yet, it was found that 76% of the mechanisms contained in the literature are present in the Constitutive Acts. Based on these mechanisms, it was possible to present a conceptual framework for Government Data Governance (GDG) applied to PSB. The GDG subordinate to public governance was represented through the mechanisms of leadership, strategy and control; the interaction between the PSB and the 167 GDG mechanisms distributed in four dimensions: Governance, Quality, Management and Compliance. It is expected that the proposed framework will serve as a reference for future research on GDG and allow both the PSB and other GFD Bodies to implement the GDG mechanisms that are most appropriate to their realities.
Public policies and evolution of information technologies
Authors: Torres Manrique Jorge Isaac
Published: January 2024

The free development of peoples is directly related to public policies. This requires a serious, sequential and sustainable commitment of state management. For their part, the referred public policies must address the different aspects that imply the development factors, in which interdisciplinarity must be considered. However, it should be noted that it is essential that public policies should also include the promotion of the use and implementation of information technologies in their various evolutionary stages (such as: new technologies, intelligent technologies, smarter technologies, future technologies). Regardless of the level of development of the people, the presence of information technologies is of vital importance, because people cannot live disconnected from the global reality, which is manifested in accordance with information technologies. In this sense, it is clear that the commitment of state management is twofold. That is, with the development of the people and with information technologies.

The effect of a conventional procedural act as its constitutive element
Authors: Wolwiak Ireneusz
Published: January 2024

Przepisy regulujące przebieg postępowania rozpoznawczego przed sądem powszechnym w sprawach cywilnych zawierają również treści odnoszące się do uprawnień stron podejmujących określone czynności w celu udowodnienia zasadności swoich twierdzeń. Poszczególne jednostki redakcyjne aktu prawnego nie zawierają wszystkich elementów związanych z podejmowaniem przez stronę odpowiednich zachowań. Pojedynczy przepis ujmuje jedynie daną myśl ustawodawcy. Dopiero wyznaczony zbiór przepisów pozwala wskazać wszystkie stawiane przez kodeks1 wymagania dotyczące zachowania strony, dla których wprowadzono nazwę: czynność procesowa. Z uwagi na sekwencyjny przebieg postępowania cywilnego ustawodawca wyznaczył cel realizacji tych zachowań dla poszczególnych czynności procesowych. Nie zawsze jednak zachowanie stron, które korzystają ze swoich uprawnień do dokonania czynności procesowej, zmierza do jego osiągnięcia. Dlatego też wprowadzając kolejne zmiany do kodeksu, prawodawca zamieścił w art. 41 zakaz korzystania z uprawnień niezgodnie z ich celem. Pojawiło się więc pytanie o skutki dokonania czynności, która nie zmierzała do osiągnięcia celu związanego z jego realizacją przez ustawę. Czynności procesowe związane są bowiem z określonymi przez ustawodawcę skutkami. Jeżeli zatem taki skutek zachowania strony byłby niezbędnym elementem czynności procesowej, to działanie strony zmierzające do osiągnięcia stanu rzeczy, który nie jest celem czynności, powinno prowadzić do jej bezskuteczności. Taki wniosek będzie jednak dopuszczalny tylko wówczas, gdy rezultat czynności procesowej zostanie zakwalifikowany do zbioru reguł konstytutywnych. W celu jego wyprowadzenia posłużono się wypracowaną w nauce konstrukcją czynności konwencjonalnych w prawie.
Badanie zagadnienia przeprowadzono metodą formalno-dogmatyczną, opierając się w działaniach badawczych na obowiązujących przepisach prawa procesowego cywilnego z ich rozszerzeniem na kontekst systemowy dziedziny prawa cywilnego. Przede wszystkim jednak skupiono się na wykorzystaniu elementów rozumowania formalno-logicznego wraz z analizą językową tekstów prawnych. Na zakończenie działań badawczych wykorzystano rozumowanie dedukcyjne, kierując się zasadami dostatecznej racji i metodą argumentacji prawniczej.
W podsumowaniu rozprawy zawarto zdanie o włączeniu reguły następstwa do reguł konstytutywnych czynności procesowych. Stan rzeczy wywołany działaniem strony, w wyniku jej dążenia do osiągnięcia celu czynności procesowej, pozostaje w teleologicznym związku z jej zachowaniem w celu spowodowania odpowiedniego rozstrzygnięcia sądu. Brak takiego związku staje się więc podstawą twierdzenia, że czynności te nie mają wpływu na przebieg postępowania.
