A weakly inhomogeneous vibrating membrane and the solotone effect in two dimensions
Authors: Bason Gregory L.
Published: April 2024

The phrase solotone effect refers to a persistent irregular pattern within a set of eigenvalues. This effect arises when the underlying differential equations contain discontinuities. Models of the Earth contain such discontinuities and research into solotones was originally motivated by vibration problems in geophysics. More recently, solotone effects have been discovered within heat conduction, and within quantum wells. However, at present, only one-dimensional arrangements have been shown to give rise to a solotone effect. In this paper, we compute the eigenvalues of an inhomogeneous vibrating rectangular membrane. The resulting eigenspectra, when taken as a whole, fail to display a solotone effect. Nevertheless, we show that irregular patterns do exist within selected subsets of eigenvalues. Our analysis therefore provides the first example of a solotone effect in a spatial dimension greater than one. Furthermore, this discovery could be used to extend the solotone inverse method already implemented in one dimension.
The Influence of Anchoring and Overconfidence on Investment Decision-Making in the Saudi Stock Market: A Moderated Mediation Model
Authors: Al Rahahleh Naseem
Published: April 2024

This research sheds light on the relationships between heuristic biases and investment decisions as demonstrated by Saudi investors by establishing a mediating role for investor overconfidence in the relationship between anchoring heuristics and investment decision-making. The first to present evidence for this role, the study takes into account specific types of investment decisions – i.e. decisions to buy, sell, and engage in frequent trading. Based on a sample of 598 responses, empirical evidence is presented to show that anchoring directly increases the extent to which investment decisions are irrational and also does so indirectly through its impact on overconfidence. Given that this is the case, investors would be well-advised to critically assess the influence on their investment decision-making of overconfidence, which may, in turn, be rooted in deep-seated biases such as anchoring. Further, the potential moderating effect of trading frequency on overconfidence and investment decisions is examined and a moderated mediation model presented to elucidate the relationship between anchoring bias and investment decisions. The findings underscore the importance of understanding these biases and taking a scientific approach to trading, including by engaging in infrequent trading, to producing more rational investment decisions. Put differently, the study highlights the benefit of infrequent over frequent trading: Compared to those who trade less frequently, investors who trade more frequently are more susceptible to overconfidence and anchoring biases.

Published: April 2024

The article is an analysis of the achievements of the Society of Friends of Children - the oldest non-governmental organization in Poland operating for the benefit of the child and his family. The focus of this organization is on children at risk of social exclusion due to poverty, neglect, orphanage or disability and their families. From the beginning of its operation,in from 1919, the Society responded vividly to the care and educational needs of children and established various day and 24-hour facilities providing them with decent conditions for development, and support for families. After the end of World War II, it took special care of orphaned children returning from exile and concentration camps, hungry, homeless andneglected in education. In later years, TPD organized orphanages, kindergarten camps, environmental educational centers, and youth clubs. It established 6 adoption centers which qualified orphaned children to adoptive families. It conducted an extensive campaign of organizing summer and winter recreation for children from dysfunctional families and specialized summer camps for sick and disabled children. n the 1990s, the Society established a number of innovative, specialized institutions, such as community clubs - including sociotherapeutic centers, centers for children and families, rehabilitation centers, family counseling centers, crisis intervention centers as well as recreation centers and children's holiday homes. The work of the Society for the benefit of the child and the family is based on the principles of competence, creativity and comprehensiveness. In his current activities, he prefers the principles of: equal opportunities for all children to be brought up in the family, the subjectivity and dignity of the child, protection of his rights and education in the spirit of tolerance, respect and mutual assistance. To this end, in many cities, about one hundred social ombudsmen for children's rights have been appointed, who intervene in situations of child abuse, and solve conflict and care-and-education situations in families. In many areas of care, the Society was a pioneer, and the forms of care initiated by it entered the national childcare system in Poland.

Authors: Kokhanovska Olena , Kasatkin Oleh
Published: April 2024

In the conditions of reforming all levels of education in Ukraine in the XXI century, changes in the content, forms and methods of educational fields, in particular language and literature, the issue of developing literary culture and consciousness of students, aesthetic culture, developing the potential, critical thinking and communication skills of students of education is becoming relevant. The article updates the conceptual apparatus used in the description of literary pedagogy in the educational sphere, which requires clarification and specification of the main terms and categories of the researched issue. Attention is focused on such concepts, terms and categories as "literary pedagogy", "literary education", "reading", and "reading competence". It was determined that in domestic and foreign science, the concepts of "literary pedagogy" and "literary education" are not sufficiently developed and established, they need to be specified and detailed taking into account the signs and characteristics of the components of the term, in some sources they are identified with each other. The concept of reading literacy is considered in the context of such skills as perception, analysis, and evaluation of texts to expand knowledge and develop reading potential. The relevance of the study and implementation of literary pedagogy in the educational process of general secondary education institutions in the XXI century in the context of the problem of the attitude of modern children and youth to reading is substantiated. A brief review of the development of literary pedagogy in the historical context of the development of society is carried out. It was found that literary pedagogy is a system of methods, means and techniques of learning, education, development and formation of personality throughout life with the help of literature. The prospects for the development of literary pedagogy in the context of the introduction of its methods, techniques and tools into educational practices, the introduction of an interdisciplinary approach, the role of literary pedagogy in the development of critical thinking, ethical competence and the general culture of education seekers are outlined.
PERIODIZATION OF THE RESEARCH DEVELOPMENT ON FOREIGN CULTURAL AND EDUCATIONAL WORKERS IN UKRAINIAN PEDAGOGICAL COMPARATIVE SCIENCE
Authors: Kryvtsun Neonila
Published: April 2024

This article delves into the concept of periodization concerning the evolution of research on cultural-educational figures from other countries within the context of Ukrainian pedagogical comparativism. It sheds light on Ukrainian comparativists' emphasis on cultural-educational figures abroad, whose educational contributions and pedagogical legacies hold significance in Ukraine's historical-pedagogical field. In formulating a structured periodization, various overarching factors influencing this process were taken into account: socio-political elements (such as shifts in ideological perspectives, Ukraine's international relationships, the impact of the Russo-Ukrainian conflict, etc.); cultural-educational aspects (integration into the European educational sphere, heightened interest in foreign socio-cultural practices, the evolution of the information society, etc.); and the transformations within Ukrainian national humanitarianism and historical-pedagogical science, particularly in the realm of comparativism. The primary criterion for developing such a periodization scheme considered quantitative and qualitative changes that affected the historiographic process of accumulating knowledge on the discussed issue. This included the increase in the number of scholarly works (especially dissertations, professional articles, etc.), changes, and modifications in their substantive characteristics (methodology, introduction of new names into scholarly circulation, etc.). This study identifies three principal periods in the evolution of research on foreign figures within Ukrainian pedagogical comparativism. The initial phase, termed 'incipient' or 'initial,' spans from the 1970s to the 1980s, extending beyond the primary chronological boundaries of our research. The second period, characterized by a personalized direction in Ukrainian pedagogical comparativism, roughly spans from 1991/92 to 2004/05, denoted as the 'transitional post-Soviet' era. This phase marked notable shifts in research methodology, transitioning from a Soviet sociologized paradigm of analyzing educational-pedagogical processes to a nationally-oriented approach for study and interpretation. The third period, encompassing 2005/06 to 2025, is referred to as the 'Euro-oriented' and 'scientifically pluralistic' era. During this phase, active de-Sovietization and de-communization of national historical-pedagogical science facilitated the integration of Western European and American methodological approaches, concepts, research tools, and pedagogical ideologies. Ukraine's adoption of the Bologna Process in 2005 steered the country towards European educational standards, gradually distancing itself from Russian academic narratives due to the military aggression of the Russian Federation, ultimately leading to a clear rejection of these narratives.
THE DEVELOPMENT OF MEDIA PEDAGOGY AS A COMPONENT OF MEDIA EDUCATION IN THE REPUBLIC OF POLAND (First Quarter of the XXI Century)
Authors: Slyusarenko Nina
Published: April 2024

The publication analyzes the development of media pedagogy in Poland during the first quarter of the twentyfirst century and its role in the country's media education system. The article examines the strategy of state policy for the development of media education, studies initiatives and programs aimed at increasing the level of media literacy and forming critical thinking about media. It also examines the achievements, problems and prospects of media pedagogy in Poland, taking into account the challenges of the modern information society. The study of media pedagogy in Poland in the first quarter of the twenty-first century is important in view of the current challenges and opportunities in this field. This study aims to identify achievements and problems, as well as to identify future prospects. Understanding the strategies implemented by Poland in the field of media pedagogy can contribute to further research and offer practical recommendations for improving media education in Poland and other countries. There are contradictions in the development of media pedagogy in Poland. On the one hand, the accessibility of information through the media contributes to education and conscious consumption of news. On the other hand, the abundance of information can lead to information overload and mixing of facts with fake news, which emphasizes the need to improve media literacy. In addition, the rapid development of media technologies can lead to the loss of traditional cultural values, which also necessitates the preservation and promotion of cultural heritage. Media platforms provide an opportunity for personal expression, but at the same time can contribute to the spread of negative content, which requires effective protection against media violence and discrimination. This study is relevant given the complexity of the modern media environment and the need for a balanced approach to media education and pedagogy.
SCHOOL EDUCATION OF ROMA CHILDREN IN TRANSCARPATHIA: THE HISTORY OF FORMATION AND DEVELOPMENT
Authors: Fizeshi Oktaviia
Published: April 2024

The Roma population has always been an integral part of the demographic diversity of Transcarpathia. However, representatives of this particular national community are traditionally the least involved in educational processes. Given the rights and opportunities for equal access to education for all citizens, regardless of their nationality, as well as the need to integrate the Roma population into civil society, the problem of involving Roma children in education, which depends on a number of conditions (social, economic, ideological, etc.), is relevant. The issue of "harming" Roma children in Transcarpathia at the state level began to be addressed in the early twentieth century, both through legal regulation and by establishing the first school for Roma children in Uzhhorod in 1926. Purpose: article is devoted to the study of the history of the formation and development of school education of Roma children in Transcarpathia. The methods are content analysis of historical, historical-pedagogical, archival and reference sources on the problem under study; problem-chronological method for studying trends in the development of school education of Roma children in Transcarpathia. Results. The article deals with the historical and pedagogical retrospective of the formation and development of school education of Roma children. For the first time, the question of the need for a settled lifestyle for Roma families arose during the Austro-Hungarian Empire, when the Hungarian government issued a decree on the fulfillment of civic duty in the context of protecting the homeland on the eve of World War I and the necessity of registering Roma children, their socialization and prohibition of begging. Later, when the territory of Transcarpathia was part of the Czechoslovak Republic, the Czechoslovak government initiated the issue of involving Roma children of school age in school. In 1923, with the assistance of the Abstract of Schooling of Subcarpathian Rus in Uzhhorod, Roma children began studying in separate classes of the Uzhhorod Ukrainian School. And in 1926, twenty-two Roma children entered the first grade of the newly built Roma school, which is considered the first such educational institution in Eastern Europe. During the Soviet period, the Transcarpathian Roma maintained a secluded lifestyle, moving from one end of the country to the other in search of work, and Roma children were rarely involved in school education (mostly only in primary school). The beginning of the twenty-first century for the Transcarpathian Roma is characterized by the consolidation of actions by the regional authorities, NGOs and representatives of the Roma intelligentsia to solve the educational problems of Roma children and the gradual increase in their coverage of general secondary, vocational and higher education.
INCLUSIVE PHYSICAL EDUCATION OF STUDENTS WITH DISABILITIES: ACCENTS IN THE MODERN DIMENSION
Authors: Blavt Oksana
Published: April 2024

The relevance of the study is due to the rapid increase of students with disabilities as a result of the war and the urgent need to adapt the educational process of higher school to the challenges of the state of war. We consider the benchmarks for solving the mentioned problem from the standpoint of domestic pedagogical science with an emphasis on taking into account the determinants of inclusive education and the use of forms, means, and methods of physical education. The purpose of the research is to identify and justify the emphasis on inclusive physical education of students with disabilities in the modern dimension. The research is based on the use of a complex of general scientific theoretical methods: analysis, synthesis, systematization, and generalization. The results. It has been studied that the change of emphasis in the interpretation of the concept of disability leads to the need to provide a comprehensive approach to creating conditions that would contribute to the full realization of the inclusion of students with disabilities during their studies in higher education institutions. It was found that inclusive physical education is currently the most effective means of inclusion, the main idea of which is to ensure the psychological comfort and interest of students with disabilities in the course of classes due to complete freedom of choice of means, methods, and forms of implementation of their physical education. The main goal of modern inclusive physical education with the help of various types of motor activity is the formation and development of physical condition, physical and psychological abilities, which ensure the adaptation of students with disabilities to their state of health, the variability of the environment, caused by transformations in the social life of the country. Attention is focused on the influence of inclusive physical education on the mental sphere of students with disabilities under martial law. The necessity of focusing inclusive physical education on creating a basis for students with disabilities to gain experience in health care skills and inclusion in active motor activity aimed at improving their health is determined. For many students with disabilities under martial law, inclusive physical education is the only way to "break" the closed space, enter society, find new friends, and get an opportunity for active physical activity. Conclusions. In the conditions of martial law, inclusive physical education is primarily aimed at creating conditions for the full realization of the physical and mental development of students with disabilities during the educational process, organized based on modern general scientific and special technologies of the theory, methodology and practice of physical culture, adapted to the needs of modern times.
FORMAL AND INFORMAL MEDIA EDUCATION IN UKRAINE: PROBLEMS AND PROSPECTS
Authors: Kondur Oksana , Didukh Iryna
Published: April 2024

The article examines the current state of development of formal and non-formal media education in the Ukrainian educational space. A comprehensive analysis of the formal and informal aspects of the media education paradigm is carried out, and the key areas of their development are identified. The formal and non-formal aspects of media education are systematized, taking into account its impact on the development of media literacy and critical thinking of participants in the educational process. The media education experience and best practices of media education activities in formal and nonformal education in Ukraine are highlighted. It is determined that the media is one of the factors in the practical implementation of the theory of dialogue of cultures, and therefore acts as an important social institution of the modern information society. The current state of media literacy of teachers in Ukraine in the framework of formal and non-formal education is analyzed, and it is noted that the problem of media education requires scientific substantiation and the search for ways to modernize the system of professional development of scientific and pedagogical workers. The predominance of non-formal media education is obvious, but the availability and differentiation of media education programs provides teachers with a significant amount of opportunities for the development of personal and professional media culture. A modern teacher should become a generator of media literacy skills for participants in the educational process. Therefore, the value of teachers' media competence is gaining new importance for ensuring continuous education and sustainable development of Ukrainian society.

Equity, diversity, and inclusion (EDI) research is increasing, and there is a need for a more standardized approach for methodological and ethical review of this research. A supplemental review process for EDI-related human subject research protocols was developed and implemented at a pediatric academic medical center (AMC). The goal was to ensure that current EDI research principles are consistently used and that the research aligns with the AMC’s declaration on EDI. The EDI Research Review Committee, established in January 2022, reviewed EDI protocols and provided recommendations and requirements for addressing EDI-related components of research studies. To evaluate this review process, the number and type of research protocols were reviewed, and the types of recommendations given to research teams were examined. In total, 78 research protocols were referred for EDI review during the 20-month implementation period from departments and divisions across the AMC. Of these, 67 were given requirements or recommendations to improve the EDI-related aspects of the project, and 11 had already considered a health equity framework and implemented EDI principles. Requirements or recommendations made applied to 1 or more stages of the research process, including design, execution, analysis, and dissemination. An EDI review of human subject research protocols can provide an opportunity to constructively examine and provide feedback on EDI research to ensure that a standardized approach is used based on current literature and practice.

Published: April 2024

In recent decades, perovskite semiconductors have been developed rapidly with excellent performance in light-emitting diodes (LEDs) and solar cells (SCs). Recent reports indicated that both the highest external quantum efficiency (EQE) of perovskite materials (PEM) that can be used for light-emitting diodes and the power conversion efficiency (PCE) of perovskite solar cells have reached a very high value compared to the previous. In this study, electroluminescence from formamidinium lead bromide perovskite is presented. The spin-coating method was used to procedure simple devices with a fluorine-doped tin oxide/formamidinium lead bromide perovskite/fluorine-doped tin oxide structure. The structure showed a green luminescence with the center wavelength at 545 nm. In the future, we will study the fabrication of devices with the structural layers: fluorine-doped tin oxide / poly(3,4-ethylene dioxythiophene) : poly(styrene sulfonate) / perovskite / electron transport layer / Ag to create so-called PeLEDs.

Published: April 2024

This research investigates the effect of cobalt precursor and calcination time on the morphology and catalytic activity of Co3O4 films in the oxygen evolution reaction (OER). Co3O4 films with porous flower-like nanostructures were obtained using cobalt nitrate as a cobalt precursor, while cobalt chlorides were used to produce porous nanoneedle structures Co3O4 film. Extended annealing time at temperatures 350°C caused structural fractures in the films. Among the samples, the synthesized Co3O4 films were then evaluated as catalyst materials for the OER in alkaline 1M KOH electrolyte. Among synthesized films, the Co3O4-2-1h, synthesized using the cobalt chlorides as Co precursor and annealed at 350°C for 1 hour, exhibited better OER catalytic activity. With its porous nanoneedle structure, the Co3O4-2-1h demonstrated superior performance comparable to the state-of-the-art 20% Ir/C catalyst. Moreover, the Co3O4-2-1h film demonstrates remarkable stability for the OER in a 1M KOH alkaline electrolyte.

Published: April 2024

In this study, we present the experimental evidence demonstrating the utility of electrical double layer (EDL)-induced ion accumulation, using sodium (Na+) ion in water as model substances, on a negatively charged nanostructured surface, specifically thermally grown silicon dioxide (SiO2). This novel approach, termed Ion Surface Accumulation (ISA), aims to enhance the performance of nanostructured porous silicon (PSi) interferometers in optical refractometric applications. The experimental results show that the electrical double layer-induced ion surface accumulation (EDL-ISA) on oxidized PSi interferometers enables remarkable amplification of the interferometer output signal (the spectral interferogram), even when the bulk refractive index variation is below 10-3 RIU. This substantial signal enhancement translates into an increase in sensitivity of up to two orders of magnitude, facilitating the reliable measurement of refractive index variations with both a detection limit (DL) and resolution (R) as low as 10-4 RIU. This achievement elevates the performance of PSi interferometers in photonics and plasmonics-based refractive index platforms.

Published: April 2024

A estandarización é un proceso tanto sociopolítico e cultural como propiamente lingüístico, e constitúe unha cuestión central na política e a planificación lingüísticas. O lingüista Otto Jespersen referiuse ao xurdimento das linguas estándar como «o fenómeno máis importante na evolución da lingua en tempos históricos». Talvez por iso, a estandarización é tamén un dos fenómenos sociolingüísticos máis discutidos, comezando polo significado do propio termo e a valoración dos seus efectos, e incluíndo os debates arredor da súa natureza e alcance. É así que nas últimas décadas os estudos estandarolóxicos experimentaron unha expansión exponencial, unha diversificación extraordinaria e unha renova-ción impresionante.Este volume recolle un feixe de traballos que teñen a súa orixe nos relatorios presentados no Simposio «Estándar, norma e variación: procesos, problemas e perspectivas», organizado polo Instituto da Lingua Galega en 2021, coa colaboración do grupo de pesquisa que puxo en marcha o proxecto ESTANDAREV [La estandarización lingüística revisitada: mediatización, vernaculari-zación e ideologías lingüísticas en la España contemporánea]. As linguas estudadas son: o galego, o portugués europeo e brasileiro, o catalán, o éuscaro e, colateralmente, o castelán. Os traballos que se recollen no volume ofrecen un estado da cuestión da estandarización, os seus problemas e as súas perspectivas, ofrecen olladas novidosas sobre os estándares e os procesos de estandarización e sinalan novas vías de investigación.

Published: April 2024

Study purpose. The study purpose was to analyze the effect of moderate-intensity endurance exercise on reducing inflammation in obese women.
Materials and methods. Twenty obese women selected according to the established criteria were used as subjects. Then the subjects were divided into two groups: the control group (G1) and the endurance exercise group (G2). Moderate-intensity endurance exercise was performed by running on a treadmill for 40 minutes, with a frequency of 5 times/week for 2 weeks. Moderate-intensity was performed with 60%-70% HRmax (HRmax formula: 220-age). Blood sampling for inflammation measurement using the biomarker High-sensitivity C-reactive protein (hs-CRP) was performed before and after the intervention for 2 weeks. hs-CRP was measured using the enzyme-linked immunosorbent assay (ELISA) method. A paired sample t-test with a significant level (p ≤ 0.05) was used for data analysis.
Results. The results showed the mean hs-CRP levels between before and after the intervention in G1 (6.76±4.40 vs. 6.43±4.89 ng/mL, (p=0.641)) and G2 (6.56±3.34 vs. 2.12±1.14 ng/mL, (p=0.004)).
Conclusions. The study indicates that moderate-intensity endurance exercise has been shown to be effective in reducing inflammation levels in obese women, so individuals with obesity are advised to reduce inflammation levels through moderate-intensity endurance exercise.

Diseases such as diabetes, atherosclerosis, and hypertension are risk factors for Cardiovascular Diseases (CVDs). About 17.3 million deaths worldwide were due to CVDs in 2013 and is anticipated to be 23.3 million by 2030. Common therapies for CVDs are associated with wide side effects. Thus, herbal medicines have been regarded more due to fewer side effects, availability, cultural beliefs, and being cheap. For thousands of years, herbal medicine has been used for bacterial infections, colds, coughs, and CVDs. Cinnamon bark contains phenolic compounds such as cinnamaldehyde and cinnamic acid with protective properties that can reduce the risk of cardiovascular diseases, cardiac ischemia and hypertrophy, and myocardial infarction. Furthermore, cinnamon has antioxidant and anti-inflammatory properties and exhibits beneficial effects on the complications of diabetes, obesity, hypercholesterolemia, and hypertension which cause CVDs. Although the protective effects of cinnamon on the heart have been reported in many studies, it needs more clinical studies to prove the pharmaceutical and therapeutic efficacy of cinnamon on risk factors of CVDs. This review explains the protective effects of bioactive compounds of cinnamon on the cardiovascular system.

Multiple Sclerosis (MS) is one of the most common demyelinating autoimmune diseases that affects the central nervous system and is characterized by major immune-mediated myelin and axonal damage or axonal loss explicable to the absence of myelin sheaths. Here we present the early findings of the gene expression study of myelinogenesis-related genes of MS rat models which were treated with a novel protocol of taper up-off of opium tincture. The study included normal Lewis rats, MS rat models by induction of experimental autoimmune encephalomyelitis (EAE) without treatment, and MS rat models with a novel protocol of taper up-off treatment of opium tincture called Dezhakam-step-time (DST) in different dosages. RNA was extracted and cDNA was synthesized from the spinal cord tissue. Gene expression analysis was conducted for eight genes as markers of myelinogenesis (OLIG1, OLIG2, MBP, MYRF, PLP1, PMP22, EGF, and UGT8) using the Real-time PCR. All eight genes were down-regulated in EAE models vs. healthy controls and all eight genes were up-regulated after the taper up-off treatment of opium tincture. The most over-expression of myelinogenesis-related genes was revealed at higher dosages of opium tincture. These are the early results of a gene expression study in a multiple sclerosis model treated with opium tincture. It seems that the opium tincture method may induce the activation of myelinogenesis in EAE models which could lead to a potential treatment for improvement of neural dysfunctions in MS patients.

“Per capire qualcosa spesso vale più un’immagine che mille parole”. Questo motto, il cui autore è incerto, ben si addice a tutti i campi della medicina, e alla cardiologia in particolare. La storia della medicina va di pari passo con i progressi della rappresentazione per immagini della anatomia e dei fenomeni fisio-patologici dei diversi apparati. Per secoli le uniche immagini del cuore e delle sue patologie sono derivate da raffigurazioni artistiche copiate da preparati anatomici. Famosi e bellissimi sono, ad esempio, i disegni delle tavole anatomiche di Leonardo da Vinci. Per tutto quel tempo, i progressi della medicina sono stati lenti e difficoltosi, con modesti risultati effettivi in termini di salute e sopravvivenza dalle malattie. Solo nel secolo scorso, gli avanzamenti tecnologici hanno permesso di ottenere segnali e immagini derivanti dal cuore di pazienti viventi, sempre più precisi, realistici e oggettivi.
DNA-extraction of Daphnia and symbionts v1
Authors: Angst Pascal , D. Fields Peter
Published: April 2024

This protocol was designed for DNA extraction of about 50 adult female Daphnia magna, it should also work for 1-150 animals but with adjusted reagent volumes. For achieving HMW DNA or maximizing yield, some modifications are indicated as substeps. Before DNA extraction, animals can be freed from microbes using antibiotics (https://www.evolution.unibas.ch/ebert/lab/daphnia_dna.htm) and should be dehydrated and snap-frozen with liquid nitrogen for archiving HMW DNA.

This paper aims to address the current limitations in knowledge about e-democracy by establishing the conceptual, intellectual, and social structure of scientific literature. Hence, this paper offers an in-depth bibliometric analysis of the literature that has addressed this reality since its first publication in 1983. The most important scientific databases currently used in the academic field were consulted to achieve this objective: Web of Science (WoS) and Scopus. In the case of WoS, 540 articles were identified, 572 in the case of Scopus. The results were harmonised to obtain a final 773 articles under study. This harmonisation of results from different databases is a differential element concerning other studies in which the analysis was carried out on a single database, thus reducing a global and homogeneous vision of the possible connections and interrelationships of the realities analysed. The information collected has been processed using the Bibliometrix tool, which provides information on annual scientific production, authors, journals, topics, keywords, etc. The processing and analysis of the results has made it possible to identify research trends in the area, establish relationships between them and detect future research opportunities for the e-democracy phenomenon.
