ALGI MORSKIE – NIEKONWENCJONALNY SKŁADNIK ŻYWNOŚCI
Authors: KARWACKA MAGDALENA , CIURZYŃSKA AGNIESZKA , JANOWICZ MONIKA , GALUS SABINA
Published: December 2024

Background. In recent years, there has been a growing interest in substances obtained from marine algae, such as dietary fiber, hydrocolloids and bioactive substances. It results from a growing awareness of the impact of nutrition on health, which leads to the search for food ingredients that may have a beneficial effect on the human body. Results and conclusions. Marine algae, naturally occurring in four groups differentiated by their dominant pigment, are a rich source of proteins, vitamins, minerals and essential fatty acids, offering many possibilities for use as a new food source and functional additive. Most often, algae are used as a raw material for the production of hydrocolloids, including alginate, agar, carrageenan and dyes, which are an alternative to synthetic additives. European Union regulations regarding the introduction of food products with marine algae are set out in three main legal documents. Products containing sea algae are subject to the same legal regulations as other food products, and their introduction to the market requires an authorization or notification process and proof of safe consumption. Research published so far suggests that algae themselves, or ingredients extracted from them, can be successfully used as additives shaping the physicochemical and sensory properties of a wide range of meat, dairy, bakery and pastry, as well as fruit and vegetable products. Introducing algae into people’s daily diet can support the functioning of their bodies and the treatment of various health problems. Due to the presented properties, the prospect of using algae in the food industry seems promising, requiring further research and innovation.
PREBIOTIC PROPERTIES OF BREWER'S SPENT GRAIN – LITERATURE REVIEW
Authors: LALOWSKI PIOTR , KRUK MARCIN , SALMAN MUHAMMAD , TRZĄSKOWSKA MONIKA
Published: December 2024

Background. Brewer's spent grain (BSG) is a by-product of beer production, constituting approx. 85 % of all generated by-products in the brewing industry, primarily utilized for livestock feed. It is characterized by high levels of fiber (40 ÷ 60 %), protein (19 ÷ 30 %), and fat (10 %). The protein occurring in BSG contains all amino acids, including exogenous ones, which are not synthesized by the human body. Results and conclusions. Brewer’s spent grain fiber mainly comprises cellulose, hemicellulose and lignin. Due to various fiber fractions, including arabinoxylan (AXs), it is suspected to possess the ability to modulate the human gut microbiota. In vitro studies conducted so far have demonstrated that BSG and extracted AXs fractions stimulate the growth of health-promoting bacteria such as Bifidobacterium and Lactobacillus, however, they also have the capacity to stimulate bacteria of the Enterobacteriaceae family. Moreover, under the influence of brewer’s spent grain, the abundance of Bacteroides and Firmicutes bacteria decreases, while the abundance of Actinobacteria increases. Additionally, it has been proven in each of the studies that the addition of BSG stimulates the synthesis of short-chain fatty acids, including propionic acid and acetic acid, with acetic acid being the most prominently affected. Brewer's spent grain may enhance the scavenging of free radicals due to the presence of phenolic compounds and increase the antioxidant activity of food. Further research, including studies utilizing a dynamic in vitro digestive system and in vivo investigations, is necessary to confirm the beneficial impact of BSG on human health.
SAFE SOY: A MICROBIOLOGICAL FACE-OFF BETWEEN ORGANIC AND CONVENTIONAL TOFU
Authors: KUKUŁOWICZ ANITA , ZBAWICKA ANNA
Published: December 2024

Introduction: The global demand for soy and soy products continues to grow steadily, with forecasts indicating further increases in the production of this commodity. While soy is primarily used as animal feed, its consumption among consumers is on the rise. Both organic and traditional agriculture aim to achieve the same goal – producing food products. In accordance with the current European Union law, all food available on the market, not only that which is labeled as organic, must be safe and provide proper nutritional values. Soy products, such as tofu, are susceptible to the growth of microorganisms due to their high water and protein content, posing a health risk to consumers. The aim of the study was to compare the microbiological quality of organic and conventional tofu. Total bacterial counts, total fungal counts, Staphylococcus aureus and Escherichia coli were determined. Results and conclusions: E. coli was not detected in the tested tofu samples, while the presence of S. aureus was found in more than half of the samples, with a maximum of 5.4·102 cfu/g. A statistical analysis did not show statistically significant differences between the origin of tofu and the total counts of fungi (p = 0.8293) or S. aureus (p = 0.5673), but revealed significant differences in the total count of mesophilic bacteria contaminating tofu depending on their origin (p = 0.0191). In particular, a higher number of these microorganisms was found in organic tofu samples (7.8·102 cfu/g) compared to conventional ones (1.7·102 cfu/g). The highest level of fungi (1.2 ÷ 4.8·102 cfu/g) was observed in 8 % of organic tofu samples. The results obtained emphasize the importance of maintaining appropriate hygiene standards during the production and storage of tofu to ensure food safety for consumers.
Teorias de estados (liberais e) raciais: uma breve análise da comunidade cigana no Brasil
Authors: Torres Maria Tereza Zolyomy
Published: December 2024

A maioria dos Estados considerados economicamente desenvolvidos são liberais, o que implica a reflexão de que são Estados que respeitam os direitos individuais e prezam pela igualdade e liberdade. No entanto, teorias clássicas mostram esse cenário de forma diferente. Desde o fim da escravidão e períodos de descolonização, o racismo não conseguiu se desvincular dos Estados, tornando-se institucionalizado e estrutural dentro da máquina política e social. O presente trabalho refletir a respeito das teorias clássicas que abordam o racismo institucional na forma de regime político e, ao final, pensar o percurso da comunidade cigana dentro do Brasil. Para isso, adota-se a abordagem quantitativa, com ênfase no método indutivo, debatendo o tema de forma argumentativa-expositiva, exaltando a utilização de referencial bibliográfico e recursos midiáticos (podcast). Como um dos principais resultados, é possível perceber que Estados que foram explorados colonialmente e tiveram o espectro eu versus o outro, por mais que sejam multiculturais e multiétnicos, possuem um regime baseado na raça e na etnia.
História da educação moderna e contemporânea: breve marco teórico
Authors: Rolim Wânia Maria de Oliveira
Published: December 2024

Este artigo tem como objetivo analisar momentos históricos relevantes na educação, nos séculos XIX e XX, destacando suas transformações ao longo do tempo. A pesquisa bibliográfica percorreu a história moderna e contemporânea, explorando, inicialmente, as características históricas que iniciaram e abrangeram quase toda a Europa. Em um segundo momento, constatamos que, ao longo desse período, a história da pedagogia evoluiu para a história da educação, sofrendo transformações concomitantes ao desenvolvimento, enfatizando a educação como ciência. A escola assumiu o papel de ponderar a ideologia e sua atribuição social no contexto pedagógico. Na pedagogia contemporânea, destacam-se as deias de filósofos como Johann Heinrich Pestalozzi, Johann Friedrich Herbart, Friedrich Fröbel e John Dewey, cujas ideias reverberam na didática e nos métodos de ensino, catalisando mudanças profundas e significativas no campo da educação. A análise histórica da educação não apenas oferece um panorama abrangente do passado, mas também lança luz sobre as dinâmicas presentes e futuras do cenário pedagógico.
Dor social e cuidados paliativos: considerações a respeito do trabalho do assistente social junto a pacientes em cuidados paliativos oncológicos
Authors: Alves Gabriel Caetano dos Santos
Published: December 2024

Discutir a respeito do processo saúde/doença, é pensar diversos fatores que impactam a vida do paciente, desde o diagnóstico ao meio a qual o mesmo está inserido. Quando falamos em pacientes oncológicos, sobretudo em Cuidados Paliativos, nos remetemos a pessoas com história de vida e com queixas que vão para além de um protocolo clínico, e que, por razão de um processo de adoecimento, vem perdendo a sua identidade, proporcionando ao paciente uma experiência de dor social, que não pode ser tratada com uma prescrição ou aplicação de medicação. Logo, este estudo se trata de uma revisão integrativa de literatura que visa debater a respeito da dor social e como a mesma pode ocasionar sofrimento físico, a qual evidenciou que a ausência de suporte social, seja ele físico ou financeiro, possui relação direta com a dor física. Deste modo, a ausência de suporte social é preditivo para a dor física.
Pedagogia jurídica e participação democrática no Brasil
Authors: Dantas Caio Livio Sulpino
Published: December 2024

O artigo trata do ensino jurídico brasileiro conduzido pelo fio historiográfico que remonta do Brasil colônia ao Brasil contemporâneo. Em diálogo com os estudos críticos pós-coloniais, procura discutir a introdução da educação jurídica no Brasil e suas consequências pela ótica do poder. Pergunta-se: de que forma os poderes dominantes, por meio do direito, da cultura, da educação, vieram a constituir o perfil dos operadores do direito? Igualmente, busca-se compreender como o ensino jurídico brasileiro, em diálogo com o funcionamento das instituições nacionais importadas do norte global, foi responsável por um específico perfil de formação de bacharéis. Perfil acrítico à compreensão das nuances conflituosas dos arranjos operados no processo de instauração democrática. Por conseguinte, admitindo-se que, em sua maioria, as carreiras jurídicas no Brasil precedem dos mecanismos de controle social garantidores da incursão de sujeitos verificados nas funções públicas através da educação; e admitindo-se que historicamente o saber-fazer jurídico está intimamente estruturado para a composição de quadros burocrático-patrimônio-institucionais; apontar-se-á, pelo fio histórico da pedagogia jurídica, influências que comungaram com a diplomação em leis e operatividade do direito brasileiro sob moldes conservadores e mesmo antidemocráticos.
MÂŞÎ-ZÂDE FİKRÎ ÇELEBİ’NİN KAYIP MESNEVİSİ ŞÜKÛFEZÂR VE EKSİK BİR NÜSHASI
Authors: Yalçınkaya Yağız
Published: December 2024

On altıncı asırda yazdığı mesneviler ile adından söz ettiren şair Mâşî-zâde Fikrî Çelebi (ö. 1574-5), eserleri ile günümüze ulaşma talihine erişememiş isimlerdendir. Şairin şimdiye kadar ele geçen tek eseri, 2007 senesinde tanıtılıp 2017’de neşredilen Ebkâr-ı Efkâr isimli mesnevisidir. En meşhur telifi olduğu anlaşılan bu eser dışında tezkirelerde Fikrî’ye atfedilen ve şimdiye kadar hiçbir nüshasına ulaşılamayan beş mesnevi daha bulunmaktadır. Bunlardan biri, çalışmamıza konu olan Şükûfezâr’dır. Mesnevinin tespit edilen eksik bir nüshası üzerinden, şimdiye kadar hakkında adı dışında bir bilgi bulunmayan eseri tanıtmak çalışmanın amacını teşkil etmektedir. Şairin ölümünden 115 sene sonra istinsah edilmiş söz konusu nüsha eksik olduğu için anlatılan konunun başlangıcı ve sonu elimize ulaşmamıştır. Buna rağmen mevcut kısımdan yola çıkarak Fikrî’nin eserini kaleme alırken tema ve kurgu bakımından Kırk Vezir Hikâyeleri’nden esinlenip kahramanların bir kısmına Şehnâme’den isimler verdiğini söylemek mümkündür. Ancak mesnevide özgün hikâyeler ve kahramanlar da bulunmaktadır.
Çalışmamızda eserin Süleymaniye Kütüphanesi Yazma Bağışlar Koleksiyonu 7253 numarada kayıtlı nüshası tavsif edilip yazar ve eser hakkında değerlendirmeler yapılmış, daha sonra örnekler beyitler eşliğinde mesnevi özetlenerek Fikrî Çelebi’nin şimdiye kadar gün yüzüne çıkmamış bu eseri tanıtılmak istenmiştir.

Current Conjuncture and Price Situation in the Sugar Market in Ukraine
Authors:   National Scientific Centre "Institute of Agrarian Economics", Parkhomenko Liudmyla
Published: December 2024

The current state of development of the domestic sugar
market is considered. It is determined that the traditional raw
materials for sugar production in Ukraine are sugar beets of
domestic production, grown almost in full by agricultural
enterprises. It is determined that the price situation in the
domestic sugar market is quite predictable, since it is closely
related to production volumes, stocks and demand for the sweet
product. It is concluded that in order to stabilize the domestic
sugar market and weaken Ukraine's dependence on imports of
liquid fuels, it is necessary to diversify sugar beet production on
the basis of organizing the production of bioethanol from
intermediate products of sugar beet processing at the capacities
of sugar and distilleries.

La ética de la inteligencia artificial en educación: ¿Amenaza u oportunidad?
Authors: Sánchez-Bolívar Lionel , Escalante-González Sergio , Martínez-Martínez Asunción
Published: December 2024

Background. In the current era of technological advances, the development of artificial intelligence has experienced a significant surge in its development and application in the last two years. AI is used to create virtual personas with realistic voices and facial expressions, generate automatic text, and more. Its contributions to human life are undeniable, but where are the limits of its use established? Is its use ethical? Aim. This study aims to analyze the ethical boundaries of artificial intelligence use in academic and educational contexts. Method. To do this, a mixed approach is used. First, a systematic review of scientific literature on artificial intelligence was conducted using the Web of Science database. Subsequently, a qualitative SWOT analysis was employed to analyze and discuss the findings. Results. As a result, it is important to note that the use of artificial intelligence for generating texts is a valuable and beneficial tool for the study and use of languages, as it allows for the creation of speeches in other languages almost instantly. However, weaknesses were also identified, such as the risk of plagiarism in educational, academic, and university environments. Conclusions. Therefore, establishing ethical standards and limits on the use of AI is a fundamental basis for supporting its utilization.
MELANOCRATIC ROCK OF THE SYENITE-TVAITOSITE SERIES OF THE CHERNIHIVKA CARBONATITE MASSIF (AZOV REGION)

The results of mineralogical studies of melanocratic apatite-enriched albite-pyroxene rocks of the Chernihivka carbonatite massif are presented. The studied rock was discovered by drilling among alkaline syenites. This rock is represented by vein- like body (thickness up to 30-50 cm). The rock-forming minerals are aegirine-diopside, albite, ferruginous phlogopite, amphibole (edenite-katophorite series) and apatite (up to 20%); accessory — calcite, allanite and pyrite. The studied rock is similar by mineral composition and high apatite content to tvaitosites and tvaitosite-pyroxenites of the massif, which are more distributed in the northern and central parts. However, it differs from them in the composition of phlogopite and amphibole. The latter is not characteristic for typical tvaitosites and tvaitosite-pyroxenites. The obtained preliminary data make it possible to put forward only hypothetical considerations regarding the genesis of this rock. Quit possible their origin could be related with separation of alkaline essentially aqueous fluids from the primary carbonatite melt with subsequent migration into hosted alkaline syenites. The subsequent reaction of these fluids with hosted rocks could lead to the recrystallization of initial feldspar to albite and appearance of secondary calcite, phlogopite, amphibole, and apatite. At the same time, it is assumed that tvaitosites – tvaitosite-pyroxenites series were formed as result of syenite melt differentiations (pyroxene fractionation), since they are composed of the same minerals as the hosted alkaline syenites and main difference between these rocks is only in proportion of pyroxene.

The object of the study is biotite granite exposed in the open pit of the Znamianka dimension stone deposit in the village of Subottsi, which is located in the marginal northeastern part of the Kropyvnytskyi massif. The aim of the study is to investigate the anatomy of accessory zircon and monazite crystals, the chemical composition of the latter, and to define the U-Pb monazite isotopic age. Previously, the U-Pb zircon age of these granites was determined at 2062 ± 11 Ma, while the inherited core of one of the crystals yielded a concordant age of 2787 ± 24 Ma. The results of our study show that zircon crystals often contain inherited cores derived from the substrate rocks. The mineral composition of inclusions in monazite has been studied. It has been found that one of the monazite fractions is characterized by significant direct discordance, significantly increased uranium content, and a much higher 206Pb/208Pb ratio than the other fractions. In our opinion, this is due to the capture of uranium by the crystals of this fraction shortly after their crystallization. Such scenario is realistic, given the presence of epigenetic inclusions in some monazite crystals. Without taking this fraction into account, the weighted average age is 2024.8 ± 4.7 Ma. Thus, the results of uranium-lead dating of zircons differ markedly from the results of monazite dating. This may be due to different crystallization times of zircon and monazite from the granite melt. Another, more likely reason for this difference in numerical values of isotopic ages is the presence of well-diagnosed relict cores inside many zircon crystals, which are at least Neoarchean in age. It is quite likely that zircon crystals with no relict nuclei were captured by ancient radiogenic zircon during crystallization, which causes some (about 40 Ma) difference in isotopic dating.
Aldosterone and Potassium in Heart Failure: Overcoming This Major Impediment in Clinical Practice
Authors: Khan Laibah Arshad , Jamil Adeena , Greene Stephen J , Khan Muhammad Shahzeb , Butler Javed
Published: December 2024

Aldosterone is a key regulator of fluid and electrolyte balance in the body. It is often dysregulated in heart failure (HF) and is a key driver of cardiac remodelling and worse clinical outcomes. Potassium regulation is essential for normal cardiac, gastrointestinal and neuromuscular function. Serum potassium fluctuations are largely determined by aldosterone, the final step of the renin–angiotensin–aldosterone system. Dyskalaemia (i.e. hypokalaemia and hyperkalaemia) is prevalent in HF because of the disease itself, its therapies and related comorbidities such as chronic kidney disease. Prognostic implications of abnormal serum potassium follow a U-shaped curve, where both hypokalaemia and hyperkalaemia are associated with adverse outcomes. Hypokalaemia is associated with increased mortality, starting from potassium <4.0 mmol/l but especially at potassium <3.5 mmol/l. Hyperkalaemia, along with increasing arrhythmia risk, limits the use of lifesaving renin–angiotensin–aldosterone system inhibitors, which may have long-term survival implications. The advent of novel potassium binders aims to manage chronic hyperkalaemia and may allow for uptitration and optimal dosing of guideline-recommended therapy. This review discusses the impacts of dyskalaemia in HF, along with management strategies, including the relevance of potassium binder use in optimising HF treatment. Current and potential future aldosterone-modulating therapies, such as non-steroidal mineralocorticoid receptor antagonists and aldosterone synthase inhibitors, are also discussed.

The article deals with results of airborne laser scanning, which was undertaken with drone above selected locations of kurgans of the Sargat culture in the middle Irtysh river basin (Omsk region) and its correlation with total station data of terrain survey. The selected scanning area covers imposing “Princely kurgans” situated on a plowed field and small mounds inside birch forest. The scanning results were processed with various filters for further creation of a digital terrain model (DTM), and then based on DTM, a topographical relief of the area under study was presented with a step of 1.0 m and of 0.1–0.2 m for sites of kurgan groups’ locations. Structures visible on DTM are coincided in quantity, size and relative position with previously recorded kurgan mounds. Besides already known archaeological objects DTM allows identifying structures similar to small kurgans mapped during terrain prospection, but requires further clarification in a course of electromagnetic survey or excavation. Combination of field and cartographic approaches provides estimation of topography particularities and hierarchy of kurgans various in size and remoteness. Small kurgans are mapped at lower hypsometric levels and distinctly close to the origins of the ravines. “Princely kurgans” were accommodated to dominant heights of foremost river terrace what was decisive in landscape exploitation, i.e. new territory markers were erected and thus transformation of landscape into social sense occurred. The particularity of the graveyard functioning was reconstructed based on data recorded during excavation of various kurgans in different sides of the area under study.

Quatre années de service sanitaire en santé
Authors: PERCIVALLE Alain , PROUVOST-KELLER Bernard , PRADIER Christian , DROUOT Cyril
Published: December 2024

Le décret instituant en 2018 le Service Sanitaire des Etudiants de Santé (SSES) avait pour ambition de permettre un développement de la prévention primaire dans la population générale pour prévenir les risques liés aux comportements à risques dans des domaines tels que la nutrition, l’activité physique, la santé sexuelle ou bien la consommation de produits psychoactifs (PPA). Le SSES est aujourd’hui un dispositif original dans la formation des étudiants de santé avec pour ambition de développer des compétences peu enseignées dans leur cursus : la pluri professionnalité, le management de projet, la communication en public etc. L’expérience de la mise en œuvre de ce SSES au sein de l’Université Côte d’Azur sur le thème des PPA fait ici l’objet d’un examen critique. Si l’intégration du SSES dans l’enseignement des différentes filières en santé est en cours, on peut s’interroger sur la réelle possibilité de proposer une démarche projet dans un environnement dominé par une approche magistrale de l’enseignement. Si de fait on a mis en place des dispositifs pour enseigner des compétences, nous sommes limités par les moyens mis à disposition pour évaluer ce type d’apprentissage. Enfin l’ambition de faire du SSES un moyen de lutte contre les inégalités sociales et territoriales d’accès à la santé semble largement mis de côté dans l’organisation actuelle de cet enseignement.
Evaluation du niveau d’usage des solutions bureautiques des étudiants cadres de santé à l’entrée en formation
Authors: MARTIN Loïc , LOQUETTE Sabrina , GILLOT Timothée
Published: December 2024

En France, le contexte d’un bouleversement numérique dans les établissements de santé nécessite de transformer les métiers et de simplifier les organisations. Le cadre de santé, maillon central des organisations hospitalières, se doit d’acquérir des compétences informatiques et numériques. Face au manque de littérature sur ce sujet notre question de recherche permet d’identifier et de mesurer le niveau d’utilisation des solutions bureautiques des étudiants cadres de santé à l’entrée en formation.
Cette recherche est une enquête rétrospective par questionnaire, utilisant une approche méthodologique mixte qualitative-quantitative.
157 questionnaires ont été inclus entre 2017 et 2021 sur un Institut de formation des cadres de santé Français. L’étude souligne que le niveau d’usage de solutions bureautiques reste globalement relativement classique et centré sur les options de bases proposées par Word® et PowerPoint®.
Il semble y avoir un écart entre les injonctions à s’emparer de l’ambition numérique et une réalité d’usage bien différente pour les cadres de santé. L’arrivée prochaine dans la formation initiale d’enseignements sur le numérique peut être une première étape à cette nécessaire montée en compétences.
ON THE GENERIC COMPLEXITY OF THE DISCRETE LOGARITHM PROBLEM IN LUCAS SEQUENCES
Authors:   Sobolev Institute of Mathematics, Rybalov A. N.
Published: December 2024

In this paper, we study the generic complexity of the discrete logarithm problem over Lucas sequences. This problem was exploited in the 1990s by the New Zealand cryptographer P. Smith to create an analogue of the classic Diffie — Hellman protocol, in which exponentiation modulo an integer is replaced by the operation of adding the elements of the Lucas sequence. It is proved that, given the worst-case intractability of the discrete logarithm problem in Lucas sequences and P = BPP, there exists a subproblem of this problem for which there is no polynomial generic algorithm. Thus, this result justifies the application of this algorithmic problem to public-key cryptography, where generic hardness is very important, i.e., hardness for almost all inputs. To prove the theorem, we use the method of generic amplification, which allows us to construct generically hard problems from problems that are hard in the classical sense. The main component of this method is the cloning technique, which combines the input data of a problem into sufficiently large sets of equivalent input data. Equivalence is understood in the sense that the problem is solved similarly for them.
AXIOMATIZABILITY AND DECIDABILITY OF UNIVERSAL THEORIES OF HEREDITARY CLASSES OF MODELS OF FINITE AND INFINITE LANGUAGES
Authors:   Sobolev Institute of Mathematics SB RAS, Ilev A. V.
Published: December 2024

In the paper, hereditary classes of L-structures are studied with language of the form L = Lfin ∪ L∞, where Lfin = ⟨R1, R2, . . . , Rm, =⟩ and L∞ = ⟨Rm+1, Rm+2, . . .⟩, and also in L∞ the number of predicates of each arity is finite, all predicates are ordered in ascending of their arities and satisfy the non-element repetition property. A class of L-structures is called hereditary if it is closed under substructures. It is proved that the class of L-structures is hereditary if and only if it can be defined in terms of forbidden substructures. A class of L-structures is called universally axiomatizable if there is a set Z of universal L-sentences such that the class consists of all structures satisfying Z. The problems of the universal axiomatizability of hereditary classes of L-structures are considered in the paper. It is shown that hereditary class of L-structures is universally axiomatizable if and only if it can be defined in terms of finite forbidden substructures. It is proved that the universal theory of any axiomatizable hereditary class of L-structures with a recursive set of minimal forbidden substructures is decidable.

Does debt diversification impact the value of companies? Evidence from Brazil
Authors: Thirion Correia dos Santos Rodrigo , Albanez Tatiana
Published: December 2024

Purpose: The main objective of this work is to investigate the impact of debt diversification on the market value of Brazilian listed companies in the period 2010-2021.
Design/methodology/approach: We used a sample of 206 Brazilian listed companies from 2010 to 2021. Panel data regression models were estimated, with the dependent variable represented by the market value of firms through three different proxies and the explanatory variables through three different heterogeneity indices, in addition to control variables.
Originality: The use of different forms of debt is a phenomenon present in the reality of firms. However, how this characteristic of the debt structure affects the value of companies is a topic that still needs to be investigated in depth in emerging markets, considering the specificities of these markets. In Brazil, the credit market is characterized by high banking concentration and the significant presence of development banks, in addition to an institutional environment with lower creditor protection and lower levels of corporate governance, creating a distinct environment from previous research.
Findings: It was observed that the greater the heterogeneity of firms’ debt, the higher the market value of companies, pointing to the importance of debt diversification in mitigating agency costs and increasing firms’ efficiency. The results highlight the importance of considering the characteristics of the local market in the effectiveness of creditor monitoring.
Practical implications: This result contributes to the decision-making process of shareholders and managers in the Brazilian market, by showing which factors can maximize investments made and, consequently, increase the value of companies.
Lyra mínima y educación sentimental en los folletos populares íbero-americanos
Authors: Chicote Gloria
Published: December 2024

This paper proposes the analysis of a selection of popular pamphlets published in Spain and America in the 19th and 20th centuries, referring to the representation of feelings and love relationships. The starting point is an article in which I attempted a comparison of the pamphlets of the Imprenta Vanegas Arroyo with the Robert Lehmann-Nitsche Creole Library, and a recent work in which I extended the comparisons to a collection of Spanish sheets gathered at the University of Geneva. The corpus of analysis was constituted with sheets from Spain, Mexico and Argentina that include lyrical and lyrical-narrative compositions, aimed at young women and men, which can be analyzed as norms of sentimental education. The purpose is to introduce us to the particular treatment of these themes in the manifestations of popular printed literature. A visit through the poems and also through the explicitly stated rules of socialization allows us to study the process of construction of the subjectivities of modern culture in the Ibero-American sphere and enables comparisons between materials printed and consumed in different cultural contexts.
Tabaré Etcheverry: la formación de un intérprete popular
Authors: Albarado Juan Carlos
Published: December 2024

Una biblioteca personal se forma no solo por las lecturas que tal o cual autor o intérprete haya podido realizar en su vida, también forman parte de su universo otras manifestaciones culturales que deben ser tenidas en cuenta: la radio, la prensa escrita, los cancioneros, entre otras cosas. El presente trabajo intenta mostrar cómo pudo haberse formado -aunque sea parcialmente- la «biblioteca» de Tabaré Etcheverry, un intérprete algo soslayado de aquel movimiento musical de la década del 60 y el 70 del pasado siglo, que se denominó Canto Popular Uruguayo. De esta forma se vislumbra un panorama que tiene en cuenta no solo las relaciones interpersonales de un compositor o sus antecedentes musicales, sino también otros factores que, en ocasiones, son olvidados o minimizados a la hora de pensar en la formación o los antecedentes de los artistas.
Las quintillas de ciego en las relaciones de fiestas novohispanas (siglo XVII)
Authors: Krutitskaya Anastasia
Published: December 2024

This paper aims to analyze the use of the quintillas de ciego in the printed accounts of festivities of the 17th century New Spain, including the antecedents of the late 16th century and the poetic competitions. The jocose and sometimes burlesque tonality of these compositions is emphasized, so that they acquire a narrative function and underline the humorous nature of the festivity that was recreating spaces appointed to construct the local community.
