Ultra-high performance concrete with metal mine tailings and its properties: a review
Authors: Li Qiuming , Feng Xiaoxin , Liu Yue , Jia Yuan , Liu Gang , Xie Yuantao
Published: May 2024

Metal mine tailings (MMT) are a kind of industrial solid waste, with an increasing accumulation year by year, which has seriously damaged the ecological environment. Incorporating MMT in ultra-high performance concrete (UHPC) is an effective means to achieve green sustainable development, which can not only make wastes be resources and prevent pollution but also save raw material costs and reduce energy consumption. However, metal mine tailings contain complex and diverse metal oxides and other chemical substance and even contain certain radioactive elements and heavy metal ions. These factors can affect the corrosion resistance of UHPC, accelerate its aging and damage, and in addition may have serious impacts on the environment and human health. This paper summarizes the material properties of MMT and its application in UHPC; analyzes the effects of MMT as powder or fine aggregate on the workability, mechanical properties, durability, and leaching toxicity of UHPC; and elaborates the hydration products, interfacial transition zone, and pore structure of UHPC incorporating MMT (MMT-UHPC). Based on previous research results, the relationship between flowability, flexural strength, porosity, and compressive strength of MMT-UHPC is established.
Aplasia cutis congenita as a complication of early interstitial laser embryo reduction in a case of monochorionic triamniotic triplet pregnancy ‒ a case report
Authors: Kaul Anita , Singh Chanchal , Gupta Ila
Published: May 2024

Objectives

Monochorionic multiple pregnancies are being increasingly encountered. Early embryo reduction by interstitial laser is an option of therapeutic intervention. The patient counseling is mainly focused on miscarriage and fetal demise but this case report highlights that the counseling also needs to mention the possibility of developing Aplasia cutis congenita post intervention and that interstitial laser though technically feasible can have rare complications.

Case presentation

This was a uncommon form of twinning diagnosed as monochorionic triamniotic triplet pregnancy where the parents wanted to continue with a single fetus. Interstitial laser was performed in two of the embryos, which became papyraceous. The newborn on delivery was seen to have extensive skin scarring on the trunk which was diagnosed as Aplasia cutis congenita.

Conclusions

Awareness on complications on early interstitial laser procedures beyond miscarriage and fetal demise and the psychological impact on the parents of seeing the scarred neonate for the first time, if they have not been made aware of this complication.
Exploring FSO link performance in varied atmospheric conditions to optimize 5G communication with a polarized quasi-diffuse transmitter
Authors: Desai Nirav S. , Rajput Sandeep J.
Published: May 2024

Free space optical (FSO) communication is an innovative technology that holds immense promise for numerous applications thanks to its high data transmission rates, rapid scalability, cost-effectiveness, superior security, and comprehensive capacity access techniques for Gbps data transmission. FSO communication relies on the Earth’s atmosphere as the medium, which introduces atmospheric disturbances that have driven the development of spatial diversity techniques aimed at enhancing the technology’s performance. Our proposed system employs a polarized quasi-diffused system with a fork as a spatial diversity scheme, which eliminates the need for multiple transmitters. We have developed a model that integrates both simulation designs to achieve optimal results. The proposed model has demonstrated excellent performance under various atmospheric turbulences, including rain, fog, and haze, exhibiting a very high maximum quality factor, improved received power, and better bit error rate (BER). Finally, we have obtained, analyzed, and extensively discussed the simulation results to provide a comprehensive understanding of the proposed model’s potential benefits. Our simulations show a maximum quality factor of 23 compared to existing models in much better, a 34 % increase in received power, and a 31 % decrease in BER compared to existing models. These results highlight the potential benefits of the proposed model for FSO communication systems.

Since the initial discovery of Dyakonov surface waves at a flat infinite interface of two dielectrics, at least one of which is positively anisotropic, extensive research has been conducted towards their theoretical and experimental studies in materials with positive anisotropy. The potential applications of these waves were initially limited due to the stringent conditions for their existence and the requirement for position anisotropy. In our study, we present the theoretical prediction and experimental observation of a novel type of Dyakonov surface waves that propagate along the flat strip of the interface between two dielectrics with negative anisotropy. We demonstrate that the conditions for surface waves are satisfied for negatively anisotropic dielectrics owing to the specific boundaries of the strip waveguide confined between two metallic plates. We study such modes theoretically by using the perturbation theory in the approximation of weak anisotropy and demonstrate that the electromagnetic field distribution in these modes is chiral. Experimental verification of theoretical predictions is made in the microwave range using 3D-printed negatively anisotropic water-dielectric metamaterial slabs. The existence of Dyakonov surface waves in negative crystals prompts a reassessment of the list of materials suitable for practical realization of these waves in the visible and infrared ranges. Due to the ability of the considered modes to transmit chiral light, they have potential in the sensing of chiral organic molecules.
The influence of tourism on the development of urban space: Comparison in Hanoi, Danang, and Ho Chi Minh City
Authors: Tran Thuy Thu , Nguyen Tuan Tran , Pham Huong Lan
Published: May 2024

Tourism is not only a driving force behind the development of many urban areas in Vietnam, but also a cause of accelerating problems such as tourist overload and great pressure on infrastructure. The study’s purpose is to evaluate the impact that tourism has had on the development of metropolitan regions in Hanoi, Da Nang, and Ho Chi Minh City, which are the three most popular tourist destinations in Vietnam. These effects are measured through two indicators: land consumption and land use efficiency (LUE). Research data are collected through two main sources: Vietnam General Statistics Office (with population and tourist data) and JAXA (with land use data). These data were collected and compared over two periods: 2010–2015 and 2015–2020. Research results have shown that consumption is increasing in all three localities, and all three cities are expanding spatially. In particular, the period 2015–2020 shows a higher level of land consumption than the period 2010–2015. However, LUE witnessed the opposite result when the period 2010–2015 showed more efficiency than the later period. Thus, all three urban areas tend to grow more if we count the amount of tourists as residents in that locality over time. This impedes future sustainable tourism development.

Published: May 2024

A mechanistic modelling of the adsorption processes onto individual minerals presenting in the near- and far-fields can greatly enhance the credibility of long-term safety assessments of granite-based geological repositories. In this study, the titration and U(VI) adsorption characteristics of chlorite, one of the major minerals of rock fractures, have been studied. Potentiometric titration curves at two ionic strengths (0.1 and 0.4 mol/L NaCl) are successfully interpreted by considering protonation/deprotonation reactions on generic edge sites (≡SOH) in the framework of a non-electrostatic surface complexation model (SCM). The adsorption of U(VI) on chlorite was reached after 24 h, the adsorption kinetics can be described by a pseudo-second-order model. A non-electrostatic SCM with three surface complexes (≡SOUO2
+, ≡SO(UO2)3(OH)5 and ≡SO(UO2)3(OH)7
2−) was set up based on pH edges of U(VI) at adsorption equilibrium in the absence of CO2. Additional, experimental data measured as a function of U(VI) concentration, solid-to-liquid ratio and carbonate concentration were well reproduced by the proposed model. Finally, parallel experiments were conducted using X-ray photoelectron spectroscopy (XPS) to analyze the variation of U(VI) surface species speciation at different pH values. The good agreement between SCM prediction and XPS analysis demonstrates the reliability of the model in predicting and quantifying the radionuclides retention by chlorite.

Aquaculture is one of the fastest-growing food sectors, producing almost 50% of fish for human consumption worldwide. However, relying on fish meal and oil for aquaculture diets is not sustainable economically or environmentally. Aquaculture feeds also contain terrestrial plant ingredients with indigestible forms of phosphorus (P), of which 70%–80% can be released into aquatic environments. This P influx contributes to eutrophication of freshwater ecosystems that can lead to anoxic conditions. This study explores a more sustainable diet for salmonids, an important and valuable seafood. Our aim was to test ingredients with highly digestible forms of P in nutritionally balanced portions to support fish growth and reduce P loading. We determined the digestibility of three feeds containing raw, extruded, and enzymatically processed microalgal co-product of Nannochloropsis oculata compared to a conventional diet. We also quantified how much P was retained and excreted. We detected highest growth in trout fed enzymatically processed co-product feed, though it was not statistically different (p = 0.846) from growth of fish fed the reference or other co-product diets. The enzyme-treated, microalgal co-product ingredient and diet had comparable values for P digestibility and solid P excretion to the reference diet, but the lowest average solid P excretion of all test diets. Trout fed the enzyme-treated diet had the highest P retention, while the reference diet had the lowest (p = 0.0429). Trout fed the enzyme-treated diet had the lowest (p = 0.0174) and negative dissolved P excretion, while those fed the reference diet had the highest. Results showed that enzyme-treated N. oculata co-product maintains digestibility, increases P retention, and reduces dissolved P excretion compared to the reference diet in rainbow trout. These findings encourage follow-up research to design and test growth performance of diets containing enzyme-treated microalgal co-product as sustainable trout aquafeed.

Evaluación de la calidad del agua mediante el uso de macroinvertebrados como bioindicadores en el Río Toribio de Ciénaga – Magdalena
Authors: Pinzón Candelario Fanny M. , García Pinto Cindy L. , Avila Treviño Jazmin A.
Published: May 2024

La calidad del agua en diversos ecosistemas acuáticos ha cobrado gran relevancia en la actualidad debido a las afectaciones que se presentan por el impacto antropogénico, es por esto, que países desarrollados han realizado planes de manejo de los ecosistemas basados en su mayoría en el uso de índices fisicoquímicos que brindan una data instantánea acerca del estado del recurso y de acuerdo a estos índices, establecen normatividad sobre el manejo de dicho recurso. Por ello, en la actualidad el uso de bioindicadores ha tomado gran relevancia a la hora de evaluar ecosistemas acuáticos, ya que pueden evaluar no solo la calidad en términos fisicoquímicos sino la calidad ecológica de todo el ecosistema.
En este sentido, la investigación pretendió evaluar la calidad del agua del Río Toribio utilizando los macroinvertebrados como bioindicadores, aplicando el índice biológico BMWP - Biological Monitoring Working Party-. El estudio fue de tipo descriptivo ya que se recogieron datos fisicoquímicos y de las diferentes poblaciones de macroinvertebrados presentes en tres estaciones establecidas en la zona baja del Río Toribio en dos épocas pluviométricas del año: una de lluvia y otra seca. Para ello se realizó captura de especímenes, identificación y clasificación taxonómica para posteriormente realizar la aplicación del índice BMWP, con el fin de establecer la calidad ecológica del ecosistema. Dentro de los datos obtenidos de los muestreos realizados, uno de los más notorios es la diferencia de macroinvertebrados presentes en las dos épocas estudiadas (temporada seca y temporada de lluvia) y cómo estas condiciones afectan la presencia o ausencia de estas especies.
Wives, Daughters and Sisters: Noble Women in Medieval Lithuania (13th–15th Centuries)
Authors: Petrauskas Rimvydas
Published: May 2024

The history of medieval women in Lithuania a little-known topic. This is due to two reasons. Firstly, the long-dominant research tradition, which has given the main role to the history of “great men”, has undoubtedly left women on the margins of studies. Secondly, the state of research has been, and continues to be, largely determined by the availability of the sources. Of all the rulers of Lithuania during the pagan period, only the names of Mindaugas’ wife and both of Algirdas’ wives are known with certainty. Sensing this gap, some of the rulers’ wives were “given” names by later chroniclers.The situation concerning the sources regarding the wives and daughters of the nobility is similar. For example, of the 26 most influential nobles of the time of Grand Duke Vytautas, in 14 cases, we do not know the name or origin of the wife. Nevertheless, the processing and compilation of the rather scattered material on the Lithuanian noble women allows us to draw some conclusions about the political and social system of the Lithuanian medieval state.Women played an important role in the world of the nobility. As wives, daughters, and sisters, they established and maintained ties between relatives, both at home and (in the case of rulers) abroad. Successful marriages often determined the trajectories of men’s careers, and sometimes even of individual families. However, they mostly remained in the silence of the sources and, thanks to the conjuncture of the sources, they appear before us first of all as pious foundresses, preservers of the memory of the family, and guardians of children.
Judicial Autonomy of Vilnius and 16 January 1566 Privilege of Sigismund Augustus – Guaranteeing the Rights of Self-Government in the Context of Judicial Reform
Authors: Klovas Mindaugas , Urmański Antoni K.
Published: May 2024

In 1387, Jogaila’s privilege granted Vilnius the Magdeburg law and guaranteed the judicial autonomy of its citizens. Vilnius citizens had the right and the obligation to conduct their legal affairs in the courts of the Vaitas, the Bench judges and the Council, which started to function from the moment the privilege of self-governance was granted or shortly afterwards, and to be governed by Magdeburg law. The preservation of judicial autonomy had to be constantly taken care of, and the Vilnius city authorities did this by securing confirmatory privileges of self-governance and, if necessary, the ruler’s injunctions against their violation by the Vilnius Palatine and Bishop, whose courts some times violated the judicial autonomy of Vilnius. In this respect, one of the critical moments was the reform of the courts of the Grand Duchy of Lithuania and the renewal of the Statute of Lithuania in the pre-union period (the 1560s). During the reign of Sigismund Augustus, King of Poland and Grand Duke of Lithuania, the City of Vilnius was granted as many as three Confirmation privileges, which renewed the rights of self-governance and ensured the inviolability of the city’s legal autonomy during the period of judicial reform and the adoption of the Second Lithuanian Statute. The last one, on 16 January 1566, crowned the intense struggle of Vilnius citizens during the years of great changes in the Grand Duchy of Lithuania.
“Relief Necessary for the Orphaned Children”: Wet-Nurses for Foundlings in Vilnius in the Second Half of the Eighteenth Century
Authors: Jakulis Martynas
Published: May 2024

The article focuses on the wet-nurses for foundlings in Vilnius in the second half of the eighteenth century when the number of children abandoned by their parents grew significantly. Wet-nurses who nursed foundlings have already received some attention in previous historiography, however, there have been no attempts to more thoroughly explore who were the women employed by hospitals and other charitable institutions as wet-nurses, what were the conditions of their employment, and how important could the income earned from this work have been in supporting their households. The research, based primarily on two distinct lists of foundlings and wet-nurses from 1789 and 1790 (see apendices), reveals that the wet-nurses were married Catholic women who had given birth several months earlier. The sources show that, throughout the second half of the eighteenth century, their monthly payment of 8 złotys remained unchanged despite inflation or other economic processes as well as the the increase in demand of women able and willing to work as wet-nurses for foundlings when the numbers of abandoned children grew significantly. Nevertheless, such employment provided women with, albeit low, but permanent and–if the nursling did not perish early–lasting income. The research demonstrates that at least some of the wet-nurses were married to artisans and merchants, and resided in Vilnius and its suburbs, not, as was usual in other European regions, the countryside, although there are indications in later sources that foundlings were actually placed with nurses of the surrounding countryside. The registers of baptisms and marriages reveal that at least some of these women were married, baptized their own children at the parish church of St John, and acted as godmothers to the children of other parishioners. However, the data on the social status of women employed as wet-nurses for foundlings is insufficient to confirm that–just like in other European cities–they were destitute and came from the lowest strata of society.
“Under the Law and Customs of War”: Treaties and Prisoners of War
Authors: Petrilionis Antanas
Published: May 2024

The law of war in the Middle Ages extended beyond the considerations of when to initiate a war (the concept of ius belli), the treatment of prisoners, and the permissibility of plunder and destruction. These dimensions were shaped by the contributions of medieval jurists and, significantly, by the influence of Christianity. Despite the concerted efforts to regulate warfare, certain practices persisted, such as the capture of peasants, women, and children – the non-combatants. The expansion of Christianity to the East, particularly to the Baltic Sea region, saw these principles advancing hand in hand, especially through the Teutonic Order and Western nobility. This article endeavors to analyze, primarily drawing from normative sources, the criteria for becoming a prisoner of war during the conflicts involving the Teutonic Order, the Grand Duchy of Lithuania, and the Kingdom of Poland in the fourteenth and fifteenth centuries. It explores the process of prisoner distribution and examines the prevailing customs and rules outlined in treaties. Notably, the peace treaties of Salynas (1398), Thorn (1411), Melno (1422), and Brest (1435) highlight evolving formulations in the quest to define who qualified as a “prisoner of war,” the conditions for regaining freedom, and the challenges surrounding the effectiveness of international treaties on the matter of captives.
Law as a Gift and Reciprocal Gift of the Monarch in the Grand Duchy of Lithuania (on the Example of the 1447 Common Noble Privilege).
Authors: Polishchuk Volodymyr
Published: May 2024

The article analyzes the concept of “gift”, which is considered in the categories of mentality, through the concept of “legal consensus”, using the preamble of the common noble privilege of Casimir in 1447 as an example. The study combines diplomatic, semantic and structural anthropological approaches to read and interpret the legal act. The “gift” is considered as an element of the common language between the ruler and the subjects of the GDL. The terms “donatio” and “recompensatio” are analyzed in detail. The preamble of the common noble privilege justifies the granting of noble rights by the monarch as a reward for the gifts of his lordship (“доброты, ласкы и дары”/“bono, graciarum et libertatum”). The anthropological understanding of the phenomenon of “gift” as a phenomenon of the customary culture of the late medieval and early modern society of the GDL becomes important. Some issues of translation of latin legal monuments into ruthenian are considered.
Ruthenian Documents of the Chancery of Alexander Jagiellon, Grand Duke of Lithuania from a Paleographic Point of View
Authors: Jurkevičius Andrius
Published: May 2024

The article examines paleographic specifics of Ruthenian documents of Alexander Jagiellon (1492–1506), Grand Duke of Lithuania. We looked into 17 documents of this ruler, kept in Lithuania and Poland. The examination of Alexander Jagiellon’s Ruthenian documents enabled us to establish the following: 1) the documents were written on two types of material – parchment or paper – using black or brown ink; 2) the documents were authenticated with pendant or applied seals of the Grand Duke of Lithuania, while other means of authentication such as signatures of the ruler or his officials were not detected; 3) individual letters in the texts of the documents are enlarged and/or decorated; 4) in all these documents, the slant of the letters varies (the letters are either vertical or slanted to the left or right); 5) some letters (mostly consonants) are raised above words, even though they make only a small part of all letters in the documents; 6) some words are made shorter by omitting vowels; 7) words are often (but not always) separated by spaces; 8) letters in individual words are almost never connected. The paleographic analysis of Alexander Jagiellon’s Ruthenian documents confirms an idea (expressed in historiography as early as in the last century) of the conditionality of the term “cursive” and manifestation of some traits of semi-uncial in Ruthenian documents of the Chancery of the Grand Duke of Lithuania in the 16th century. The Ruthenian documents of this ruler display features of both cursive and semi-uncial or even uncial. We also attempted to identify individuals (Alexander Jagiellon’s scribes) who could have been responsible for the preparation of documents and documents that could have been written by the same individual.
When at home: a phenomenological study of zoom class experience during the COVID-19 pandemic
Authors: Zhang Minglei
Published: May 2024

In a preliminary study conducted during the early phase of the COVID-19 pandemic, i.e., the spring 2021 semester, this paper explores the integration of Zoom into online learning while in-person teaching was paused. This pilot study aims to offer initial insights to improve inclusivity and accessibility in teaching and learning. While more robust empirical research has since been conducted to enhance Zoom-based learning environments, the findings from this study remain foundational and complementary to ongoing and future pedagogical research in online education and digital pedagogy. During a one-month ethnographic study involving five participants, including college students and professors, Maurice Merleau-Ponty’s phenomenological concepts were applied to investigate how students and educators navigate temporal and spatial challenges in Zoom meetings and the strategies they use to overcome these obstacles. Additionally, an experiential autoethnography was employed to document personal experiences beyond the Zoom classroom, providing insight into participants' daily lives. By capturing a snapshot of the initial transition to remote education, particularly through Zoom meetings, this study offers valuable information for improving the online learning experience for both students and educators.
The role of the placenta in breast carcinogenesis in the offspring
Authors: Sofoudis Chrisostomos , Sarantis Nicole Dimitra , Salvanos Georgios
Published: May 2024

Introduction: Following the long-established hypothesis that breast cancer originates in utero under hormonal influence, the authors of this study aim to examine whether placental weight and morphology relate to an offspring’s future risk of developing breast cancer. Methods: A comprehensive search of the Pubmed and Scopus online databases for studies regarding the influence of the placental weight and morphology on an offspring’s future breast cancer risk was performed. The search included articles published between 1990 and 2023. Results: In total, five studies examining the issue under question emerged. Two studies found only a weak and non-significant positive association between placental weight and an offspring’s breast cancer risk and two did not find any association at all. The fifth study demonstrated that increased placental volume elevated breast cancer risk in the offspring. The presence of a placental tumor was also strongly positively associated with cancer risk. Fibrin deposition and hemorrhage, on the other hand, had a protective effect. Conclusion: Further prospective studies with long-term follow-up are needed in order to establish an association between placental morphology and a daughter’s future breast cancer risk.
Molecular Autopsy With Banked Cord Blood Reveals Brugada Syndrome in Past Sudden Death Case

Published: May 2024

Molecular autopsy has recently been gaining attention as a means of postmortem diagnosis; however, it is usually performed using the victim’s blood sample at the time of death. Here, we report the first case of a deceased infant with Brugada syndrome whose diagnosis was made with banked cord blood. A seemingly healthy 1-year-old male infant collapsed while having a fever; this collapse was witnessed by his mother. Despite cardiopulmonary resuscitation, he died of ventricular fibrillation. No abnormalities of cardiac structure were identified on autopsy. Genomic samples were not stored at the time because of a lack of suspicion for familial arrhythmia. Five years later, his sister showed Brugada electrocardiogram pattern while febrile from Kawasaki disease. Their father showed a spontaneous type 1 Brugada electrocardiogram pattern. A heterozygous SCN5A p.R893C variant was found by genetic testing in the proband’s father and sister. Furthermore, the proband’s genetic testing was performed using his banked cord blood, which identified the same variant. Family history of Brugada syndrome with an SCN5A-R893C variant and clinical evidence led to a postmortem diagnosis of Brugada syndrome in the proband. Identification of this variant in this case later contributed to verifying SCN5A-R893C as a pathogenic variant through data accumulation. Banked cord blood may prove useful for conducting molecular autopsies in previously undiagnosed cases of sudden death in which genomic samples were not stored.
Perspectivas teóricas feministas em Relações Internacionais
Authors: Simioni Fabiane , Kyrillos Gabriela de Moraes , Vidal Camila Feix
Published: May 2024

O objetivo principal desse trabalho foi contrastar duas perspectivas feministas em Relações Internacionais. A primeira é uma abordagem interna de autoras britânicas e estadunidenses, que buscam situar as mulheres dentro do Sistema Internacional. A segunda é uma perspectiva “forasteira” de autoras latino-americanas e decoloniais, que se concentram na condição das mulheres a partir das estruturas sociais que (re)produzem a dominação masculina na política internacional. Em termos metodológicos, trata-se de uma análise comparativa limitada a quatro autoras representativas da divisão geopolítica do conhecimento entre o norte e o sul globais. O trabalho destaca a complexidade que as diferentes epistemologias feministas trazem para as análises das RI e argumenta que a abordagem decolonial com perspectiva feminista tem potencial para apoiar a superação dos limites das abordagens feministas inside.
(Re)countering multilingualism and refugee-background students in Australian compulsory education: A systematic literature review
Authors: Heinrichs Danielle H. , Fillmore Naomi , Daliri-Ngametua Rafaan
Published: May 2024

Compared with nations around the world, Australia has one of the highest rates of refugee resettlement per capita. Approximately 40 per cent of newly arrived refugees in Australia in 2018–19 were under the age of 18 and close to 90 per cent spoke a language other than English. Given that education is compulsory until the age of 16 in most states and territories of Australia, young people labelled as refugee-background students (RBSs) are tasked with navigating the English-only education system, in which their multilingualism is often viewed as a barrier; however, there are increasing calls for research to focus on the positive, affirmative practices of RBSs through a strengths-based approach in education, to counter a ‘damage-centred’ and deficit discourse. Thus, this article presents a systematic literature review of studies conducted in Australia with RBSs between 2010 and 2022. Specifically, this review explores the strengths-based multilingual practices of RBSs in compulsory education in Australia. Inspired by RefugeeCrit theory, we seek to highlight strengths-based examples of RBSs multilingual practices as examples of counter-narratives to the prevailing deficit discourse, while remaining attentive to issues of trauma, agency and multilingualism.
«Mon ouvrage est scientifique, mais d’un ordre peu commun». Nostalgia, Catolicismo y Progreso en el pensamiento de Joaquín de Yrizar Moya (1793-1878)
Authors: Iñarra-San-Vicente Xabier , Artola-Renedo Andoni
Published: May 2024

Joaquín de Yrizar Moya (1793-1878) es un representante peculiar de la Contrailustración. Nacido en una familia guipuzcoana de élite, durante su larga vida experimentó una profunda evolución ideológica: liberal exaltado en su primera juventud, se distanciaría de los principios ilustrados mientras adoptaba tesis cada vez más conservadoras hasta abrazar el carlismo. Militar y matemático de formación, escribió varias obras sobre el origen de las lenguas, las naciones o los mitos, y publicó opúsculos contra las que él consideraba ser derivas materialistas de la modernidad. Sus textos revelan la nostalgia por una sociedad confesional y jerárquica, pero, al mismo tiempo, sostienen que el conocimiento del pasado puede contribuir al progreso, entendido este como una realización de los planes de la Providencia. Esta visión del progreso aúna elementos aparentemente contradictorios, mostrando las diversas lecturas que este concepto pudo adquirir en la primera sociedad liberal.
¿Historia o histeria? Nacionalización simbólica griega y memoria urbana de Tesalónica
Authors: Rueda-Laffond Jose-Carlos
Published: May 2024

Tesalónica es una ciudad singular, paradigma de cosmopolitismo en un pasado reciente y hoy la segunda urbe en importancia de Grecia. El texto se enfoca desde la perspectiva de la simbología político-cultural y los estudios de memoria. En primer término, aborda la tensión histórica entre mitos nacionales del Estado griego y la ductilidad de distintos etiquetajes (helenismo, bizantinismo, balcanismo). En su segunda parte, estudia algunos rasgos del mapa simbólico de la memoria urbana en la Tesalónica actual atendiendo a sus espacios emblemáticos. Todo ello permite contrastar unos campos de representación definidos por la reivindicación y la fluidez identitaria fundadas en la apropiación nacional de las huellas clásicas o bizantinas y en la relativa invisibilidad de las presencias musulmana o judía.

ABSTRACT. In the conditions of military aggression against Ukraine by Russia, Ukrainian society not only did not lose its social orientation, but on the contrary, focused attention on the prospects of a humane, socially oriented society. Providing a barrier-free environment for people with disabilities in tourism is a marker of the social development of society and is related to the prospects of the country's economic development. People with disabilities and their family members, guardians and others are concerned about the problems and tasks faced by Ukrainian society. Solving these problems was limited due to the state's financial problems. In connection with the increase of people with disabilities due to war and environmental problems, progress in the activation of social orientation and the development of inclusiveness of communities, Ukraine's accession to the EU - the question of the possibilities of people with disabilities to lead an active social and productive life is being updated. That is why the issue of creating a barrier-free environment in tourism, as one of the directions of social and physical rehabilitation and ensuring the normal life of people with disabilities, cannot be ignored. Research methodology. To achieve the set goal, research and analysis of Ukrainian and foreign scientific literature, including authors from the countries of the EU, the United States, and Japan, was carried out. The main differences in the definition of concepts have been identified, the information obtained has been summarized and the directions for further research have been identified. The results. In the article, the main approaches to the definition of synonymous concepts «barrier-free tourism» are analyzed. The similarity, but not the identity, of the trmins is determined. The main problems and barriers that people with disabilities face due to the lack of a complex approach to solving an actual problem have been identified. Scientific novelty. On the basis of the study of the definition of the concept of «tourism for people with disabilities», the definition of the concept of «barrier-free tourism» is given. The рractical significance. The presented study offers a complex approach to solving the problem of implementing complex accessibility of a barrier-free tourist environment with an emphasis on web, Internet, and software accessibility for people with disabilities.

Objective. To analyse the impact of digitalisation on passenger rail transport and assess its role in increasing the competitiveness of this sector. Methods. The following methods were used to achieve the goal and solve these tasks: literature and research analysis - the authors conducted a thorough analysis of scientific papers, studies and publications covering the topic of digitalisation in the field of public transport; comparative analysis - comparing different approaches and technologies in the field of digitalisation allowed to identify the most effective methods and strategies that can be implemented in public transport; forecasting and modelling - using models and forecasts to assess future development Results. It has been determined that the introduction of digital technologies will automate a number of processes in railway traffic management, increase efficiency and reduce operating costs, increase passenger satisfaction and loyalty, reduce the risk of accidents and incidents, increase revenues by improving the quality of services and reduce costs by optimising resources. In general, it is proved that digitalisation contributes to the creation of new and more flexible tariff offers that are focused on the individual needs of users. Scientific novelty. The authors propose directions for the digitalisation of passenger rail transport and identify key aspects related to the competitiveness of passenger rail transport. A methodological approach to assessing the effect of reducing travel time is proposed, the basis of which can be the economic value of time, and an alternative approach to assessing the effect of reducing travel time involves using the value of the gross regional product per capita generated in the region per unit of time as a cost equivalent of the saved time. Practical significance. The results of our study can be used by railway passenger companies to modernise existing systems and introduce new technologies, create new products and solutions that support the digitalisation and optimisation of public transport, develop new business models, optimise supply chains, improve transport efficiency and public transport safety, and improve the system of monitoring and responding to emergencies..
