The Effect of Financial Literacy on Financial Behavior and its Impact on Financial Decisions – The Case of Lebanese University Students
Authors: Maalouf Nada Jabbour Al , Elia Jean , Sawaya Chadia
Published: August 2023

Financial literacy is the comprehension of finance and attitudes toward financial opportunity and financial behavior. Financial acquaintance is crucial for making responsible financial decisions. In this challenging financial environment, we are living in, young people, particularly university students, must make challenging financial decisions that will impact their financial behavior. This study aims to examine the relationship between financial behavior and financial decision-making among Lebanese university students. The study is significant because it raises serious questions regarding the long-term effects of financial literacy on financial behavior and its impact on financial decision-making. The study adopted a quantitative methodology to accomplish its key goals. Students from various Lebanese universities were given a questionnaire. Using a convenience sampling method, a sample of five hundred ninety-eight participants was obtained. SPSS was used to analyze the data, namely Pearson correlation and regression analyses. The study's conclusions demonstrated the beneficial influence of financial literacy on financial behavior. Additionally, they demonstrated the beneficial effects of financial conduct on the financial judgments of university students in Lebanon. Thus, it is strongly advised that college students become financially literate so they may make wise financial decisions. Moreover, for Lebanon to be among the top countries with the highest financial literacy the Lebanese Ministry of Education and Higher Education should include within the curriculum of the intermediate and secondary classes some financial educational programs, workshops, and seminars. This will let students have exposure to basic financial knowledge and learn its significance and need in their financial decision-making.

This study aims to determine the appropriate decarbonization technologies to reduce carbon dioxide (CO2) emissions in road infrastructure projects. Decarbonization is a process that seeks to reduce or eliminate CO2 emissions that contribute to climate change and that comes from the energy sources consumed by the transport sector. With statistical information from different studies, the most appropriate technologies were identified to control the triangle of effectiveness, productivity, and profitability derived from the costs, time, and quality of the projects associated with decarbonization technologies. The study is documentary and bibliographic, with the deductive method, quantitative approach, applied orientation, and descriptive, correlational, and explanatory types. The design is non-experimental, cross-sectional, and retrospective. The energy conversion efficiency of all technologies is identified in three domains: with fossil fuels from compressed natural gas, with natural gas, and with electricity by hydrogen electrolysis. GHG (Greenhouse Gas) emissions savings using BIM (Building Information Modeling) can reach up to 14% and 30% of emissions and 47% and 65% when the scope of maintenance and rehabilitation is restricted, and pavement construction is excluded.

Sustainability Evaluation: Measurement of Dimensions in Accredited Universities in a Developing Country
Authors: Gómez Johnatan Castro , Torres Javier Alirio Sánchez , Rendón Paola Andrea Ortiz
Published: August 2023

Due to the new paradigm of university education, universities must implement sustainability in their missionary functions and administrative areas to increase their reputation, obtain external financing and create a competitive advantage. For this reason, this research aims to propose a university sustainability evaluation model for accredited institutions, in the context of developing countries where the implementation of sustainability presents notorious lags. A measurement tool for student perception of university sustainability was built through a review, grouping of dimensions, expert testing, pilot testing, exploratory and confirmatory analysis. The survey was applied in nine accredited universities to 1.276 students of various semesters and professions. The review of the literature yielded various evaluative models on university sustainability. Thus, the theoretical results and the quantitative validation of the findings validated the constructs and as a result, the dimensions of the institutional framework, campus operations and missionary functions stood out with high statistical significance, evidencing the relevance of the measurement instrument. Therefore, these categories are considered central to the evaluation processes, just as greater emphasis should be placed on the dimensions referring to missionary functions. This research is innovative because it is one of the first evaluation models of university sustainability formulated from the perspective of the student in a developing country for institutions that must account for their progress in the implementation of sustainability, such as universities with high quality accreditation.

The aim of the study was to find out the effect of adding nanocitrate of Mn, Zn and Cu to the diluent for ram spermatozoa cryopreservation on its quality and ability for fertilizing. The experiment was carried out on six clinically healthy breeder 2–4-year-old rams of the Texel breed. The received ejaculates of the rams were evaluated for the volume, sperm concentration and motility and then divided into control and experimental groups. Control sperm samples were diluted with lactose-yolk-tris-citrate-glycerin medium (LYTCGM). Nanocitrates of microelements were added to the medium in experimental samples of ram sperm in the following doses: Zn2+ and Mn2+ — 2.5, 5.0 and 7.5 μg/l, Cu2+ — 1.25, 2.5 and 3.75 μg/l. The diluted sperm was packaged in straws, equilibrated for 2.5 h and frozen. After thawing of sperm we determined motility, survival of sperm, activity of succinate dehydrogenase (SDH) and cytochrome oxidase (CO), activity of antioxidant protection enzymes superoxide dismutase (SOD), glutathione peroxidase (HPO) and catalase (CAT). A dose- dependent effect of Mn, Zn, and Cu nanocitrates upon their addition to LYTCGM was established. Addition of nanocitrates of Mn, Zn to LYTCGM at a dose of 5.0 μg/l increased sperm motility by 22.2% (P<0.05) and 26.0% (P<0.01), and sperm survival, respectively, by 12.6% on (P<0.01) and 5.9% (P<0.05) compared to the control. Nanocitrates of Mn, Zn at a dose of 5.0 μg/l as part of LYTCGM caused a probable increase in SDH (P<0.001) and CO (P<0.05–0.01), which indicates a high fertilizing ability of ram spermatozoa. Similarly, when Mn, Zn nanocitrates were added to LYTCGM at a dose of 5.0 μg/l, SOD activity decreased by 29.6% (P<0.01) and 38.8% (P<0.01) and HPO activity increased by 43.5% (P<0.01) and 39.1% (P<0.01), and CAT — by 40.0% (P<0.05) and 37.5% (P<0.05), respectively. At the same time, the addition of Cu nanocitrate to LYTCGM with an increase in the dose significantly reduces the activity, survival and fertilizing capacity of thawed ram spermatozoa, and also worsens their antioxidant protection.

Despite apparent disagreement in the scholarly literature on standards of pediatric decision making, a recognition that similar norms underpin many of the dominant frameworks motivated a June 2022 symposium “Best Interests and Beyond: Standards of Decision Making in Pediatrics” in St Louis, MO. Over the course of this 3-day symposium, 17 expert scholars (see author list) deliberated on the question “In the context of US pediatric care, what moral precepts ought to guide parents and clinicians in medical decision making for children?” The symposium and subsequent discussion generated 6 consensus recommendations for pediatric decision making, constructed with the primary goals of accessibility, teachability, and feasibility for practicing clinicians, parents, and legal guardians. In this article, we summarize these recommendations, including their justification, limitations, and remaining concerns.
Economic Determinants of High Order Births in Russia: The Study Based on the Analysis of Regional Differentiation
Authors: Shubat Oksana M.
Published: August 2023

Introduction. Demographic problems are one of the acutest in modern Russia. Negative demographic trends which are specifically manifested in the regions of the country, actualize the study of trends, causes and consequences of the decline in fertility. This will allow developing more effective measures of state support and stimulation of the birth rate. At the same time, the study of regional differentiation is especially in demand in relation to higher-order births. An increase in the number of births of third and subsequent children is necessary to overcome negative demographic trends and increase the population in the country. The purpose of the article is to study the features of regional differentiation of high order births in Russia and to assess the influence of economic factors on them.

Materials and Methods. The demographic indicators of Rosstat for 2018–2021, presented in the regional context, were used as an information base; ratings of regions of the agency RIA Rating. The methods of descriptive statistics, correlation analysis and comparison tests were used. Based on the Tukey criterion the regions with atypical values of the birth rate were identified and described separately.

Results. The analysis has revealed a high level of regional differentiation of higher-order births; showed no relationship between the birth rate of third and subsequent children and the following economic factors in the regions: the implementation of regional maternity capital programs, the level of socio-economic development of the region and the level of well-being of families in the region. The analysis has showed that these factors are not related to the nature of the dynamics of the birth rate of third and subsequent children in the regions of Russia.

Discussions and Conclusions. The results obtained have allowed us to conclude that the determinants of high-order births in Russia are not limited to the economic conditions of the population’s life. The effectiveness of the economic measures implemented in the country to support and stimulate high-order births has not been confirmed. The results can be used to evaluate the effectiveness of pronatalist state measures. Understanding the features and causes of the emerging regional differentiation of high-order births will make it possible to build more reasonable forecasts of demographic dynamics.
Regional Youth in Search of Civic Identity: Digital Participation and the Observer Model
Authors: Abramova Sofya B. , Antonova Natalya L.
Published: August 2023

Introduction. At present, the tasks of forming civic identity actualize the issues of digital civic participation and understanding the specifics of online activism as a factor and indicator of youth civic identity. The purpose of the article is to build a typology of models of digital civic activism and analyze observational models as a mechanism for the manifestation of civic identity.

Materials and Methods. The study is based on the results of a survey of residents of the Sverdlovsk region aged 14–25 years (n = 1 150). The object includes students (schoolchildren, secondary vocational schools and higher educational institutions) and working youth. The use of correlation analysis and the calculation of power-law averages made it possible to determine the relationship between digital participation models and the manifestation of civic identity.

Results. A typology has been made based on the status of involvement, three categories have been constructed: observers, doers, digital passivists. Young people include an observer position in the forms of manifestation of civic digital activism. The group of “observers” inside is heterogeneous and can be differentiated by the intensity of the use of digital practices. It is determined that the discrepancy between self-identification as an observer and real practices of digital civic participation create internal contradictions in the formation of civic identity.

Discussion and Conclusion. The study made it possible to determine that young people’s identification of themselves as “citizen observer” is a convenient model for them, which allows them to overcome the contradictions of identity and performs a number of functions. The transformation of the position of an “observer” into an interested one and easily switching from an outside observer to an active participant and vice versa was recorded. The results can be used in the development of regional youth pro

Este artículo sistematiza la experiencia vivida producto del cambio de paradigma educativo a nivel metodológico para la enseñanza del inglés, específicamente en lo acontecido en un curso dedicado al aprendizaje de la gramática en la carrera de Inglés con Formación en Gestión Empresarial de la Universidad de Costa Rica. Estamos ante una realidad donde es indiscutible que, actualmente, en las aulas contamos con una generación que está altamente influenciada por el uso de la tecnología y que más bien podría presentar problemas para adaptarse a la enseñanza tradicional. La realidad es que muchas personas estudiantes reclaman y esperan ambientes de aprendizaje más creativos. La pandemia ocasionada por el virus SARS Cov-2 obligó a todas las instituciones educativas a replantear su modelo de enseñanza tradicional y presencial, hubo que adaptar el currículum hacia una educación remota de emergencia, caracterizada por la creación de entornos virtuales. Se concluyó, luego de este estudio, que el uso de herramientas tecnológicas por sí solas no implica innovación ni aprendizaje exitoso, se requiere que haya una metodología centrada en el estudiante, pero apoyada por TIC, el profesor se convierte en el diseñador y moderador de estos espacios. Se concluye que, si se logra la implementación exitosa de los mismos, se van a producir más y mejores aprendizajes, pero todo esto implica un cambio metodológico a lo que tradicionalmente se había utilizado.
New God for a New Paganism
Authors: Doyle White Ethan
Published: August 2023

Modern Pagan religions are past-oriented, seeking inspiration and legitimation from the pre-Christian religions that once existed in and around Europe. This has led modern Pagan groups to adopt various ideas about pre-Christian religions and their survival that stem from late nineteenth and early twentieth-century scholarship – including the notion of the Green Man. The belief that the foliate heads of medieval ecclesiastical architecture demonstrated evidence for a pre-Christian religion surviving into the High and Late Middle Ages, as articulated in its most complete form by Lady Raglan in 1939, appealed to early Wiccans such as Gerald Gardner and Doreen Valiente, who interpreted these heads as depictions of the Wiccan Horned God. By the 1990s, the Green Man had become arecurring image in the modern Pagan milieu who was increasingly incorporated into ritual, while the 2000s witnessed the growth of modern Pagan literature devoted to this new sylvan god.

Introduction. The advances in the development of science and technology currently make it possible to develop natural resources in space, mainly on the nearest satellite of our planet – the Moon. Meanwhile, the last cross-border act regulating this sphere was created in 1979, i.e. more than 44 years ago. A limited number of countries have joined such agreements. Russia, the USA and China are not involved in all of these treaties. In view of the strategic, economic and military importance of space, such a state of the legal regulation can hardly be considered satisfactory, and becomes an indirect factor in the possible emergence of interstate conflicts and confrontation. In this regard, the purpose of the publication is to consider the current state and prospects of the normative improvement of international law in the field of exploration and exploitation of lunar and outer space. Methods. The research is based on the application of logical, dialectical techniques and the methods of scientific cognition, the comparative legal and legal-technical analysis of the texts of normative acts and the materials of law enforcement practice. Results. As a result of the research, various points of view of resolving legal problems accumulated in the field of lunar and outer space exploration have been considered on the basis of both conflict of laws and material regulation, including through the use of the method of analogy of law. The results of the review have become the basis for the following conclusions: the current international (unified) norms of law in this area require systematization and updating. The completion of such a process should be the creation of a comprehensive legally binding interstate act that will allow us not only to solve public and private legal tasks, but also to combine substantive and conflict-of-laws methods of regulation.

Authors:   University of Law and Socio-Information Technology, Romanyuk Dmitry , Pershin Alexander ,   Kutafin Moscow State Law University
Published: August 2023

Introduction. The digital transformation of all spheres of society as an integral attribute of modern civilization is characterized by the sectoral penetration of high technologies in all significant applied areas. Law enforcement is no exception. It is impossible to imagine the modern work of criminal prosecution authorities without the use of numerous information retrieval systems and databases. However, users of existing software products may not think about how their functionality is algorithmized. In this connection, the purpose of the study is to investigate the matrixing and modeling of forensically significant information in the context of the digital transformation of civilization. Methods. During the research, the methods of comparative law and the method of analysis were used. Results. In the paper, the authors, relying on the information content and the implementation of embedded software functions, widely use the methods of matrixing and modeling, which have found specific application in forensic science. Conclusions. As a result of the study, it has been found that the methods under consideration have similar features. However, the differences between them are important. A proper understanding of the content of each of the methods contributes to their error-free application and evaluation of the results obtained. A special role is assigned to the correlation of methods in forensic theory and practice.

VALIDATION OF AN ORGANIZATIONAL CLIMATE SCALE IN A MILITARY HIGHER EDUCATION INSTITUTION: IMPLICATIONS FOR RESEARCH AND PRACTICE
Authors: Arregui David Alexander Calderón , Mena Marisol Josefina Godoy , Fernández Adriana Marrero
Published: August 2023

The evaluation of organizational climate is a critical factor in business management, and its importance is even greater in military higher education institutions, due to the high motivation and commitment expected from their members. However, research on this topic in Ecuador is scarce. The present study validates a scale to measure organizational climate in Ecuadorian military higher education institutions. The instrument proposed by Hernández, Garrido & Rico (2016) was applied to an intentional sample of 44 Military Engineering School (ESINGM) members. Its reliability was evaluated using Cronbach's alpha coefficient, obtaining values above 0.960, indicating high internal consistency. The dimensions of the organizational climate present in the institution were identified, and the results of the first-level statistical validation were presented. It is concluded that the scale is valid and reliable for measuring the organizational climate in this institution. In addition, this study contributes to the understanding of the organizational climate in military higher education institutions in Ecuador and may have implications for the management and improvement of educational quality in the context of higher education in Ecuador.
Physio-chemical characterisation of ultra-fine-slag-based ultra-high-performance concrete
Authors: Das Nabodyuti , Nedunuri Aparna Sai Surya Sree , Nanthagopalan Prakash
Published: August 2023

Ultra-high-performance concrete (UHPC) meets the demand of modern infrastructure due to its exceptional strength and durability. The effects on concrete strength of the size and shape of fine aggregates, and binder content and type, were investigated. Particle packing concepts were adopted for fine aggregate optimisation, and the shape of the fine aggregate was assessed using an aggregate image measurement system. Further, the effects of binder content, binder type and curing age were investigated through compressive strength, thermo-gravimetric analysis (TGA) and quantitative X-ray diffraction. Mixtures with a 2.36 mm nominal maximum size of aggregates (n.m.s.a.) and angular aggregates exhibited higher compressive strength than those with a 1.18 mm n.m.s.a. No significant increase in the compressive strength was observed in mixtures with a binder content greater than the optimum 1000 kg/m3. The study also revealed that ultra-fine slag is a feasible alternative to silica fume. The TGA and X-ray results of concrete paste samples at different curing ages showed that the degree of hydration was relatively low (38.3%) with no further significant increase beyond 7 days. This work contributes to the fundamental understanding of the effect of raw materials on UHPC strength, which helps in rational selection of materials and mixture proportioning.

Determination of the polarization plane specific rotation in gyrotropic crystals of the middle category by the spectrophotometric method
Authors: Zabelina E. V. , Shahin R. , Kozlova N. S. , Kasimova V. M.
Published: August 2023

A large number of modern functional single crystals of the middle category belong to gyrotropic media. In these crystals, when light propagates along the optical axis, rotation of the plane of its polarization is observed. In this work a spectrophotometric method was used to obtain the dispersion dependences of the rotation angle of the polarization plane. This method is based on measuring the intensity of light passing through the polarizer–crystal–analyzer system, the crystal is a polished plane-parallel plate of a uniaxial gyrotropic crystal cut perpendicular to the optical axis. Measurements were carried out on a UV-Vis-NIR spectrophotometer Cary-5000 in the wavelength range of 200—1200 nm using polarizers — Glan–Taylor prisms. Polished plane-parallel plates of known SiO2 and α-LiIO3 crystals were used as samples. The obtained dispersion dependences of the spectral transmission coefficients are oscillating. Discrete values of the specific angles of rotation of the plane of polarization of light are calculated from the extremes on these dependencies. These discrete values can be approximated by the formulas Drude, Chandrasekhar and Vyshina, depending on what determines the nature of the rotational ability of the plane of polarization of light in each particular material. For the studied crystals, dependences of the modified Drude formula of the form 1/ρ = f(λ2) are plotted, these dependences should have a linear character in the case of an ideal crystal. The obtained experimental results correlate well with the available literature data. The advantages of this method are efficiency, the possibility of obtaining dispersion dependences of the specific rotation angle of the polarization plane, the need for a single sample, the possibility of assessing the nature of the rotational ability of specific crystals, the possibility of evaluating the structural perfection of the studied crystals.

Resultados: Las especies de Mimosa, creciendo sin inóculo, variaron en crecimiento y asignación de biomasa con valores inferiores al tratamiento con inóculo, y se agruparon en tres diseños morfológicos: i) M. calcicola y M. lacerata; ii) M. adenantheroides, M. luisana y M. polyantha; y iii) M. biuncifera, M. purpusii y M. texana var. filipes. Asimismo, las ocho especies conformaron un cuarto diseño cuando crecieron con inóculo que favoreció su crecimiento y modificó sus patrones de asignación de biomasa.
Conclusiones: Los resultados contribuyen a delinear posibles grupos funcionales en Mimosa, pero se requiere la evaluación de otros rasgos funcionales para seleccionar especies con potencial en la restauración ambiental y comprender el ensamblaje de las comunidades vegetales.
Dentists have an obligation to expand their knowlodge and to contribute to knowledge
Authors: Wood Neil
Published: August 2023

Dentistry is shaped by dental research, which also drives innovation and improves oral health outcomes. As dental scientists are at the forefront of knowledge, it is important to understand their role in pushing the boundaries of research. Dentistry as a whole must promote the value of developing and funding dental research in South Africa; and draw attention to the urgent need to pay more attention to translational research. We should also emphasize the academic obligations of dental schools and faculty to advance knowledge and contribute to the literature in parallel to the provision of much needed dental services to the people of South Africa.
High molecular weight DNA extraction for marine macroalgal tissue v1
Authors: Moore Malia
Published: August 2023

This protocol details high molecular weight DNA extraction for marine macroalgal tissue. Marine macroalgae contain a variety of unique cell wall components including sulfated polysaccharides and polyphenolics. These components often co-elute with high molecular weight (HMW) DNA and lead to reduced library prep and sequencing outcomes. This protocol incorporates polyvinylpolypyrrolidone (PVPP) and β-mercaptoethanol (BME) to reduce polyphenolic contamination, and an early salting out step with potassium acetate (KOAc) to address polysaccharides. This protocol is largely adapted from an Oxford Nanopore HMW DNA extraction from Arabidopsis leaves, which incorporates the QIAGEN Blood and Cell Culture DNA Midi Kit for column cleanup. The DNA product often requires additional cleanup after elution, and we suggest the BluePippin 15kb size selection for all HMW applications.

Protocol for quantification of BdDV-1 mycovirus of Batrachochytrium dendrobatidis by qPCR v1
Authors: A. Clemons Rebecca
Published: August 2023

This protocol is used for quantifying the amount of the DNA mycovirus BdDV-1 in DNA extracts or cDNA libraries.This virus is associated with the fungus Batrachochytrium dendrobatidis (Bd), and it is known to be endogenized in the genome of a large number of Bd strains. The assay uses real time quantitative PCR with Taqman probes. Setup of the reaction is typically done in a biosafety cabinet. This protocol has been optimized on a QuantStudio 3 (Applied Biosystems).
Immunohistochemistry of Human Brain Striatum: ciliation of cholinergic neurons and astrocytes v1
Authors: S. Khan Shahzad , Jaimon Ebsy , Lin Yu-En , R Pfeffer Suzanne
Published: August 2023

We study cholinergic neurons and astrocytes of the dorsal striatum that are important components of the nigrostriatal circuit. We have shown previously that these cell types lose primary cilia in 4 mouse models of LRRK2 Parkinson’s disease (Dhekne et al., 2019; Khan et al., 2021). Here we present a method to identify the same brain region in human postmortem tissue to evaluate ciliary status. The striatum is identified morphologically and also by immunofluorescence microscopy using anti-DARPP-32 antibodies (Ouimet & Greengard, 1990; Arlotta et al., 2008). Cholinergic cell bodies stain brightly with anti-choline acetyltransferase (ChAT) antibodies and these cells are also identifiable using antibodies that recognize the choline transporter, CHT. Auto-fluorescence is decreased using Sudan Black B. We are grateful to our colleagues at the Banner Institute at the University of Arizona (Drs. Geidy E. Serrano and Ileana Lorenzini) for providing tissue and guidance (Beach et al., 2015). References Arlotta P, Molyneaux BJ, Jabaudon D, Yoshida Y, Macklis JD.

"POETISM" AS A SPECIFIC DIRECTION IN ART AND LITERATURE
Authors:   Educational and scientific humanitarian institute, National Academy of the Security Service of Ukraine, Tkachenko Anastasiia
Published: August 2023

The article examines the literary and artistic direction "poetism", a concept that is insufficiently interpreted and highlighted in Ukrainian literary studies; there is a lack of special studies of this phenomenon in European art of the 20th century in domestic Slavic studies. "Poetism" is the most vivid manifestation of avant-gardeism on the Slavic soil, which, according to many researchers, became a kind of "forerunner" of modern postmodern art. The peculiarities of the literary avant-garde on the Czech territory are determined, its origins and manifestations are clarified. The socio-political and historical background of the emergence of the Czech artistic avant-garde, manifestations of poeticism in literary creativity, in particular in Czech poetry, are studied. An overview of the theoretical foundations of poetics, program manifestos and documents was made, the program, socio-political and literary activities of the artistic group " Devětsil" were considered. Artists did not dream of enriching museums with a few perfect works, they wanted to shape life itself. Art had to descend from the heights to people, to everyday life, as a normal necessity of life. Awareness of the change of eras, the primacy of life over art are the most important features of the Czech post-war avant-garde. It is in lyricism that one feels the changeable worldview, through which representatives of the avant-garde sought to enrich both literature and culture in general. All these changes took place before the eyes of the contemporaries of the era in science, philosophy, and culture: the world, previously complete and unchanged, turned into an open stream in which everything runs and rages. Lyrization in art was marked by the awareness of the turning of the epochs and fully reconciled man with natural happiness. Lyrism filled Czech art with a fabulous atmosphere of playfulness, humor, comic and absurdity of the world. He did not create a new world, because more significant changes were needed for that, he recreated the features of a new direction.
