Abstract: Throughout the present work we intend to know if Service-Learning experiences causes positive consequences in the acquisition of competences knowledge (conceptual, procedural and attitudinal), as well as in motivation and engagement of university students. For this purpose, we analyzed the SL experiences of a group of 198 students, using the Fernández-Torres et al. (2017) questionnaire. The results indicate that students present high scores in the three types of competencies, especially in attitudinal ones, also, in motivation and engagement. In addition, we appreciate the influence caused by attitudinal competencies on motivation, and, also, on engagement. Finally, we propose and test a mediational model, where motivation is a mediating variable in the relationship of influence of attitudinal competencies on engagement. Among the practical implications we want to highlight the importance of promoting SL experiences at university level, since it not only favors the acquisition of competencies knowledge, especially attitudinal ones, but it is also for motivation and engagement. In addition, we demonstrate the impact that motivation has on SL experiences.

Archetypal Scenarios of the Future in the Images of Modern Russian Cinema
Authors: Gribakina Tatiana Eduardovna
Published: September 2023

The object of this study is the archetypal scenarios of the future proposed by the American researcher Jim Dator. The subject of the study is the images of the future of modern Russian cinema. The main purpose of the article is to correlate the models of "continued growth", "collapse", "discipline", "transformation" of the Dator with modern Russian films containing social expectations of society regarding the future and ideas about it. To date, the images of the future in general and the images of the future captured in the domestic cinema, in particular, have been little studied, which is the relevance of this study. The image of the future is understood as a holistic picture of the future that exists in a certain society at a certain period of its development. The novelty of the presented material lies in the correlation of archetypal scenarios with modern Russian films devoted to various versions of the future. The article applied its own methodology for the study of feature films, which allowed us to consider not only the content of films, but also their visual and sound series of films. The main conclusion of the study is that the selected J. Yes, archetypal scenarios are reflected to varying degrees in modern Russian films. The most common archetype is "Discipline", more saturated in visual terms, but a less common variant is the "Collapse" scenario, the third most common is the "Transformation" archetype, and the least present in Russian cinema is the "Continued Growth" scenario.
The legacy of P. Feyerabend: a look from the digital realities of the XXI century
Authors: Kolesova Ol'ga Valentinovna
Published: September 2023

The article analyzes the ways of expressing the methodological message of P. Feyerabend, implemented by modern digital reality. The object of the study is the specifics of digital reality, and the subject is the forms of implementation of P. Feyerabend's methodological message in it. Using hypothetical-deductive and hermeneutic approaches, the author correlates the positions of P. Feyerabend's epistemological anarchism with the features of modern cyberphysical reality. The comparison of the first "counter-rule" – the principle of proliferation is carried out in relation to the understanding of hybrid society and the metaverse. The principle of incommensurability, understood by Feyerabend as a condition for the absence of criteria for assessing the truth of the theory, is compared with the heterogeneity of the digital environment. The main conclusions of the study are the highlighted parallels between the principle of proliferation and the constant transformation of the actors of the digital society, evaluated from the standpoint of expanding the possibilities of creativity. The principle of incommensurability is compared with the constant generation of new conventions by the digital environment, the presence of heterogeneous modalities. The modern way of thinking is positioned in the discourse of the given "counter-rules" as the implementation of complex network thinking. Feyerabend's premise for the perception of archaic man correlates with the idea of cybernetic animism. The scientific novelty of the work consists in fixing the parallels of Feyerabend's theoretical premises and the reality of the modern hybrid world with its ways of thinking, revealing the internal contradiction of Feyerabend's position and the ambiguity of the embodiment of his methodological guidelines in a modern hybrid society.

Viscoelastic assays help in identifying disorders of clotting factors, platelet function, and detection of excessive fibrinolysis. Rotational thromboelastometry (ROTEM) assesses quantitative and qualitative aspects of whole blood coagulation which allows for the determination of the mechanism of hemostatic disturbance. This helps clinicians in targeting the correct blood component therapy transfusion. Now, using verify we aim to study platelet reactivity, VA ECMO which will reflect the platelet aggregation response to an aggregating agent like Aspirin and thus know the etiology of bleeding on VA ECMO, to know the right component therapy to be transfused with a Point of Care test. For extracorporeal membrane oxygenation, although the conventional laboratory tests are used to monitor anticoagulation on whole blood, viscoelastic tests reflect coagulation status like no other standard laboratory tests. They show the status of color propagation, formation, and stabilization. It was reported that platelet function was impaired over time in all parameters with different activators.

Mi az eredményesebb stratégia: a miozin aktivációja vagy gátlása?

Published: September 2023

A miozinmolekula működése szoros kapcsolatban áll a szív szisztolés és diasztolés funkcióival. Mellékhatásoktól mentes inotróp gyógyszerek hiányában, a direkt miozinaktivátorok és direkt miozin-inhibitorok fejlesztése jelentős szakmai érdeklődés mellett bontakozik ki. Az omecamtiv-mecarbil a direkt miozinaktivátorok leginkább vizsgált reprezentánsa, amely a közelmúltban lezárult GALACTIC-HF nagy betegszámú, randomizált klinikai vizsgálatban is eredményesnek tűnt. A szer kevésbé előnyös tulajdonságairól párhuzamosan felhalmozódott ismeretek – és a második generációs danicamtiv hasonló tulajdonságai – miatt a direkt miozinaktivátorok gyors klinikai bevezetése mégsem várható. A direkt miozinaktivátorok hatásának eredményeként a szisztolé időtartama nő – következésképp a diasztolé időtartama csökken – a kamrai kontrakciók és relaxációk üteme lassul, amelyek együttesen a diasztolés funkciózavar lehetőségét vetik fel. A direkt miozin-inhibitorok (mavacamten és aficamten) – negatív inotróp hatásuk miatt – elsősorban a hipertrófiás cardiomyopathia kezelésében nyerhetnek létjogosultságot. Az utóbbi kórállapotban jelentkező hiperkontraktilitás mérséklésével a szív hipertrófiás átalakulása is lassítható, és ez elodázhatja a hipertrófiás cardiomyopathia invazív kezelésének (pl. szeptális myectomia, szeptális abláció, szívtranszplantáció) szükségességét is. A miozinra ható gyógyszerek fejlesztése és alkalmazása kapcsán még számos kérdés nyitott, az eddigi tapasztalatok azonban azt sugallják, hogy a miozin gátlásán alapuló gyógyszeres eljárás – megfelelően választott betegkörben – hamarabb válhat a mindennapi gyakorlat részévé, mint a miozin aktivációján alapuló pozitív inotróp kezelés.

A Computational Study on Light-Induced Spin Crossover in [Fe(Tp)(CN)3]-2 in Search of Potential Building Block for Single-Molecule Magnet
Authors: Ray Soumyadip , Samanta Suvadip , mondal padmabati
Published: September 2023

Light-induced spin crossover (LISCO) in transition metal complexes has drawn attention to the researcher due to its various application in science and technologies. The interplay of LISCO with single molecular magnetism (SMM) is interesting in view of its application towards photoregulated storage devices, magnetic photoswitches. Herein, we have studied the interplay between LISCO and SMM of a Fe(II) complex ([Fe(Tp)(CN)3]-2) which is an ultimate miniature of potential building block of SMM using density functional theory (DFT) and time-dependent DFT method. The molecular structure and energy in low-spin singlet, high-spin quintet as well as intermediate spin triplet is calculated. It is found that the molecule is stable in its LS state but can undergo spin crossover upon irradiation of UV-vis light via triplet excited states. The singlet excited states are close-lying, forming a band structure. The detailed mechanism of LISCO is proposed based on the calculated potential energy cuts and spin-orbit coupling values. While the LS state of the complex has Ms=0 and diamagnetic, the HS state has Ms=±2 and paramagnetic. The calculations suggest a positive zero field splitting parameter and a reasonably small E/D value with a high magnetic relaxation barrier of 96 cm-1. Therefore, for a good SMM, the complex has to be trapped in its HS state after the SCO and reverse spin-crossover (rSCO) has to be stopped. On the other hand, the complex can be used as photoregulated magnetic switch if both the SCO and rSCO happens at the similar time scale.
Optical and scintillation properties of hybrid manganese(II) halides with formamidinium and acetamidinium cations

Published: September 2023

In recent years, hybrid manganese(II) halides (HMHs) have attracted wide attention due to their impressive optical properties, low toxicity, and facile synthetic processibility. Being effective reab-sorption-free phosphors, these compounds demonstrate the potential to be used as low-cost solu-tion-processable scintillators. However, most of the HMHs studied to date contain bulk organic cations and, as a result, are characterized by low density and low X-ray stopping power. For this reason, we studied manganese(II) halides with compact organic cations such as formamidinium (FA+) and acetamidinium (Ac+). In particular, we synthesized four new phases, two of which are characterized by octahedral coordination of manganese ions (FAMnBr3, AcMnBr3) and red emis-sion, whereas the other two have tetrahedrally coordinated Mn2+ ions (FA3MnBr5, Ac2MnBr4) and green emission. Photoluminescence (PL) and radioluminescence measurements demonstrated high PL quantum yields and reasonable scintillation light yields of acetamidinium-based compounds. In addition, unlike most known HMH-based scintillators, the discovered materials have a relatively high density, due to the small fraction of the volume occupied by organic cations, so their X-ray attenuation coefficients are comparable to the well-known oxide scintillators.
Tunable magnetic order in Fe-Mg co-doped montmoril- lonite nano-clay interfaced with amino acids.
Authors: Thapa Dinesh , Westra Steven , Kilin Dmitri , Kilina Svetlana
Published: September 2023

The present study investigates the tunable magnetic order as well as the electrostatic and magnetic interactions due to the adsorption of the amino acids (AA) on the insulating montmorillonite (MMT) nano-clay in vacuum and in aqueous medium using the first principle density functional theory (DFT). A single layer MMT clay of thickness 0.68 nm has been co- doped with impurity atoms, Fe(II) and Mg(II), each of concentration 12.5 %. Our calculated values of interaction energies suggest that the water molecules enhances the binding affinity of AA molecules due to the formation of a strong hydrogen bonding with substantial charge transfer between AA molecules (charge donor) and nano-clay (charge acceptor). We also predicted the possible transition in magnetic orders (ferromagnetism, antiferromagnetism, and ferrimagnetism) due to adsorption of AA molecules while going from vacuum to aqueous medium which has not been reported yet. Such kind of study possess potential applications in tissue engineering, pharmacology, magnetic resonance imaging, and chemical engineering.

Published: September 2023

Artificial micro/nanomotors utilizing active particles exhibit enormous potential in applications such as drug delivery and microfabrication. However, their substantial upgrade to micro/nanorobots capable of executing precise tasks with sophisticated functions remains a significant challenge. In this paper, we develop a bubble microthruster (BMT) – a new variation on the bubble driven microrobot – that focuses energy from a collapsed microbubble to create a hydrodynamic jet to exert inertial impact on nearby micro-objects. Benefiting from the easy magnetic-field guided control via gamepad, the BMT can perform real-time measurements on designated micro-objects with the assistance of high-speed imaging. By measuring the transient response of the micro-object and fitting the relaxation time, the inertial mass and density of micro-objects can be determined. Our study validates our approach by measuring the mass of polystyrene microparticles and the effective density of hollow glass microspheres, and unravel a sub-nanogram resolution that could be suitable to detect variation in mass or density of cells or embryos. The BMT technique illuminates the development of a chip-free method for biological microparticles, integrating with manipulation using microrobot and detection of physical properties. This technique may provide versatility and simplicity in complex environments compared to current methods using cantilever/resonator in microfluidic chips.
Controlling the CO2 Reduction Reaction through Dual-Atom Catalysts Embedded in Expanded Porphyrins: A DFT Study
Authors: McCarver Gavin , Yildirim Taner , Zhou Wei
Published: September 2023

In the pursuit of innovative molecular catalysts for the electrocatalytic reduction of CO2, we employed computational methodologies to investigate six Cu-based ex- panded porphyrin dual-atom catalysts (DACs). Our study revealed both large and small variations among the different DACs. Despite metal center substitutions, the highly delocalized nature of the π orbitals in the expanded porphyrin complexes led to minimal differences between the frontier orbitals. Conversely, pronounced differences emerged during hydrogen reduction. Notably, the formation of H2 exhibited low limiting potentials ranging from 0.13 to 0.43 eV, attributable to the ligand-centered activity of the expanded porphyrin. Similar limiting potentials (< 0.31 eV) for CO2 reduction indicate competition between the two reduction processes. This can be attributed to the emergence of highly favorable bridging μ2 intermediates, exemplified by *OCHO and *OH. The preference for these intermediates is expected to lead to the formation of only 2e- and 4e- products, namely H2, HCOOH and H2CO. Specifically, CuFe and CuMn DACs are poised to favor CO2 reduction to produce HCOOH and H2CO, while CuCo, CuCu, and CuZn DACs are anticipated to favor the production of H2.

Methods.

The Pan American Health Organization (PAHO), St. Jude Children’s Research Hospital, and partners in Latin America and the Caribbean collaborated in a three-phase project, beginning with a needs assessment survey of caregivers of children with cancer in Peru. Based on this finding, an interdisciplinary team of pediatric PC experts developed educational content that was designed and validated by an international committee of PC and communication experts.

Results.

The collaboration resulted in the development of an eight-module series that introduces caregivers to key concepts of pediatric PC, including management of pain, quality of life, and end of life care. The series was designed to reduce caregiver stigma associated with PC through culturally sensitive education that addresses the low levels of health literacy among caregivers in Latin America and the Caribbean. In the 15 months since the launch, these modules have been distributed throughout Latin America and were downloaded 2 825 times.

Conclusions.

Educational materials and anticipatory guidance of PC were considered to be a priority for parents and other caregivers of children with cancer throughout Latin America. The materials developed through this project have been widely utilized and are available through the PAHO website and the Together by St. Jude™ online resource.

Published: September 2023

Purpose: The aim of this study is to focus on bibliometric analysis and the concept of consumer buying behaviour to understand the evolutionary and developmental trends in the field of consumer buying behaviour.
 
Theoretical framework: Analyzing the consumer buying behaviour in the context of management is necessary and a great opportunity for future research. It is undeniable that consumer buying behaviour is a part of marketing that cannot be overlooked and this study explores the gap in management studies.
 
Design/methodology/approach:  This research method is a bibliographic analysis using data from the Google Scholar database from 2018 to 2022 to provide meaningful insights for further discussions. To collect data, Publish or Perish was used with the central database of Google Scholar. VOSviewer is also used as a tool to get a map of the relationship between authors and between searched keywords. Furthermore, Microsoft Excel is used to process the data and tree mapping from the data obtained.
 
Findings: According to the findings, a total of 275 articles were published in 2018, 264 articles in 2019, 232 articles in 2020, 191 articles in 2021, and 38 articles in 2022. In addition, the findings demonstrated a significant decline in interest in the discipline of consumer buying behaviour. The network analysis demonstrates five distinct sub-fields of inquiry regarding consumer buying behaviour. British Food Journal was the most prolific journal in terms of journal analysis for the topic of consumer buying behaviour. In terms of publication output, Wang was the most prolific author throughout the entire period analysed.
 
Research, Practical & Social implications: The information might be used by professionals, policymakers, and academics to get insight into consumers' purchasing habits. This research traces the development of academic curiosity on consumer buying behaviour and highlights research gaps in this field. By doing a bibliometric analysis, this research adds to the existing body of work on the topic of consumer buying behaviour. The results of this bibliometric study might also be used to inform decisions and policy initiatives about consumer buying behaviour.
 
Originality/value: The significance of this research is to systematise academic work on consumer buying behaviour and to provide academics and practitioners in the field with a complete review of the theoretical foundations of studies on consumer buying behaviour.

Konflik Norma Penolakan Euthanasia di Indonesia
Authors: Prihatin Endang , Anggriawan Ferry
Published: September 2023

Problems in the Human Rights Law which only regulate the right to life and not the right to die. If interpreted broadly, the logic is that if the right to live exists, then the right to die must also exist. If the state legalizes forced deprivation of life by law, then the government should also regulate the legalization of death by its own will in the law. This study aims to examine how the basic considerations of judges in rejecting the Application for Injection of Death or Euthanasia in the Decision of the Banda Aceh District Court are viewed from the perspective of human rights and how the rejection of the Application for Injection of Death or Euthanasia in the Decision of the Banda Aceh District Court is viewed from the perspective of the values of justice . The method used in this study is normative juridical with the following results; The rejection of the application for lethal injection or euthanasia in the Berlin Silalahi case for researchers is a form of injustice and violates the purpose of making the law itself. Whereas euthanasia can be considered as a way to uphold the 'Right to live' by respecting the 'Right to die' with dignity. Furthermore, the application of the practice of euthanasia in Indonesia is actually possible to implement and can bring human rights supremacy in Indonesia closer. The supremacy of human rights here is interpreted to cover human rights as a whole which previously had not been included in positive law so that they could be contained in positive law in Indonesia.

Published: September 2023

Desde hace muchos años el acuífero de La Paz se encuentra sobreexplotado y con problemas de contaminación por intrusión marina. Mediante un análisis de sólidos totales disueltos (STD), aniones y cationes principales, del 2013 al 2019, se encontró que el frente de la cuña marina considerando la isolínea de 1000 mg L-1 se desplazó una distancia máxima de 8.8 y 8 km en dos frentes principales, la zona norte delimitada entre los ejidos Chametla y El Centenario, y la zona noreste ubicada al este del ejido Chametla y sur de la ciudad de La Paz. A lo largo del periodo, las concentraciones de STD permanecieron con poca variación sin incremento significativo. La Mayoría de los pozos agrícolas muestreados presentaron concentraciones mayores a 1000 y 2000 mg L-1, a diferencia de los pozos de agua potable con concentraciones menores a los 1000 y 500 mg L-1. Se observó una alta concentración de cloruros, sodio y calcio cuya evolución fue muy similar al de los STD. Con diferentes relaciones iónicas se pudo apoyar la teoría de que el incremento y permanencia de la salinidad es debido a la intrusión de agua de mar. Sin embargo, la zona de mezcla agua dulce-agua salada se deriva de una combinación de aguas de recarga por flujo subterráneo con el agua de mar. En base a los resultados obtenidos se estima que los pozos agrícolas no han incrementado sus extracciones y que la mayoría de los pozos de agua potable todavía están fuera del alcance de contaminación ya que la zona donde se encuentran es muy dinámica y parece tener condiciones de alta permeabilidad.

Para movilizar el agua de una cuenca a otra se han realizado obras hidráulicas como los trasvases que junto con los trabajos asociados a estos han afectado múltiples factores ambientales y sociales, entre otros. En este estudio se evaluaron los efectos de trasvases en la estructura y funcionamiento ecohidrológico de la cuenca de la presa de La Muñeca localizada en el municipio de Tierra Nueva, San Luis Potosí. Se realizaron transectos de 50 m de longitud siguiendo el método Landscape Function Analysis (LFA) para medir características de la estructura del paisaje en parches con diferente cobertura vegetal y se elaboró un mapa de la cobertura del suelo. A partir de simulaciones de lluvia en estos parches e inter-parches se determinó el promedio de escorrentía y la tasa de infiltración final, que fueron mapeadas para modelar la distribución espacial de la acumulación de escorrentía. El modelo de regresión usado para mapear el porcentaje de la cobertura del suelo fue significativo (P < 0.0001). Hacia la zona oeste del área de estudio se generó mayor escorrentía por ser un área con menor cobertura del suelo, mientras que en la zona este se presentó la mayor acumulación de escorrentía y sedimentos, por encontrarse una mayor proporción de parches de cobertura densa. En general, los resultados comprueban la viabilidad de utilizar métricas, simulaciones de lluvia y modelado espacial para evaluar el funcionamiento ecohidrológico y así determinar la acumulación de escorrentía a diversas escalas del paisaje.
Âşık Veysel’in Uzun İnce Yol’unda Ezoterik Dünya Algısının İzini Sürmek
Authors: SAYAR Elif
Published: September 2023

Dünyaya geldiği andan itibaren hayatı anlamlandırma yoluna giden insanoğlu, hakikat bilgisinin peşine düşer. Tanrı’yı ve evrenin yaratılışını çözmek için kendilik bilgisine yönelen çoğu öğreti, bugüne kadar insanlığı aydınlatma yoluna gider. “Gizli olan ve bir şeyin iç yüzünü bilme” anlamına gelen Ezoterizm de ancak yorumlama ile anlaşılabilecek örtük bilgiyi içerir. Hakikat bilgisi ehil olmayanlardan gizlenerek yalnızca ehillere öğretilir. Antik çağlara dayanan ve herkese açık olmayan bu öğretinin gizil bilgisinin izi, halk şiir geleneğinin ustası Âşık Veysel’in hayat görüşünü özetlediği düşünülen “Uzun İnce Bir Yoldayım” adlı şiiri üzerinden sürülür. Veysel’in kendini, işini ve dünyayı bilmeyi nerden bildiği bilinmez; ancak olup biteni açık gözlerden daha iyi bilmesi onun ezoterik/içrek bilgi yönünden zengin olduğu görüşünü kuvvetli hale getirir. Bu çalışmada “Uzun İnce Bir Yoldayım” şiiri üzerinden Aşık Veysel’in dünyayı nasıl algıladığı, algıladığı dünyada hangi içrek/ezoterik bilgiyi sunduğu ve bu bilginin hangi sembollerle görünür hale geldiği ortaya konulacaktır.
