Authors: Karimulin R.F. , Semenenko A.I.
Published: December 2023

The search of scientifically based neuroprotective therapy for acute cerebrovascularaccident (АCA) of the ischemic type is still ongoing, and the development of new АCAtreatment methods is an urgent task of modern medicine.The aim of the work – to study the effect of different combinations of neuroprotectors,which differ in the mechanism of action, by analyzing indicators of oxidative stress in theblood serum of patients with ischemic strokes.Materials and methods. A randomized prospective controlled study of the use of the mosteffective neuroprotective complexes (NPС) in patients with ischemic typeАСАwas conducted. NPС № 1 (cerebrolysin + mexidol) and NPС № 2 (cerebrolysin + citicoline) were usedin the study.Patients with moderate and severe ischemic stroke were randomly dividedinto groups depending on the nature of treatment: 1) comparison group – receivedtraditional therapy; 2) along with traditional treatment, they received a combination ofneuroprotectors NPС № 1; 3) against a background of traditional treatment, they receiveda combination of neuroprotectors NPС № 2. The studied NPC was prescribed immediatelyafter confirming the diagnosis of ischemic type of ACA, and then approximately every24 hours for 7 days. Biochemical studies were carried out in dynamics for 1, 4 and7 days and determined the content of malondialdehyde (MDA), the activity of superoxidedismutase (SOD) and NADPH oxidase.The results. After the analysis of the obtained results in the group of patients with ischemicstroke of moderate and severe degree of severity, the inclusion of the NPC combination intraditional therapy was accompanied by a probable decrease in the activity of NADPHoxidase in blood serum per day 4 and 7, respectively, for NPC № 1: 13.3 and 25.4% and17.5 and 34.0% (p<0.05), for NPC № 2 respectively: 24.8 and 36.8% (p<0.01) and 24.1 and41.5%.% (p<0.01). In patients with severe ischemic strokes, the use of pharmacotherapy,which included NPC № 1 and NPC № 2, caused an increase in the activity of SOD in theblood serum on the 4th and 7th day, respectively, 26.5 and 48.1% and 50.0 and 72, 0%(p<0.01). A significant decrease in the serum level of MDA after 3 and 6 days of treatment,respectively, occurred when using both NPCs in severe stroke, respectively, for NPC № 1:42.7 and 60.7% (p<0.01), and for NPC № 2: 51 .0% and 68.6%.Conclusions. The use of NPC № 2 (cerebrolysin+citicoline) in the treatment of moderateand severe ischemic strokes in terms of the effectiveness of correction of serum activityof NADPH-oxidase, SOD and MDA significantly exceeded the treatment, which includedthe use of a combination of NPC № 1 (cerebrolysin+mexidol).

The aim – to establish the leading clinical and diagnostic features of patients with coronaryheart disease, including the indicators of differentiated ECG, in age and gender distribution.Material and methods. During the research, 135 patients with coronary heart disease wereexamined. Patients were divided into comparison groups based on age (age ≥60 yearsand age <60 years) and according to gender (women, men). The participants of the studyunderwent a clinical examination, general clinical, biochemical blood tests and functionalresearch methods (echocardiography, coronary ventriculography, ECG digitization based onthe own software «Smart- ECG»). The results.Patients aged≥60 years had a lower quality of life according to the EQ-VAS scale(59.34±2.40%, Δ –11.06%, p=0.026), higher values of the erythrocyte sedimentation rate(16.13±1.97 mm/h, Δ +50.89%, p=0.026) and creatinine (110.25±3.98 μmol/l, Δ +12.16%,p=0.038), lower hemoglobin values (142.18± 2.27 g/l, Δ –4.78%, p=0.021), erythrocytes(4.68±0.07 T/l, Δ –5.26%, p=0.011) and platelets (224.80± 8.04 G/l, Δ –10.60%, p=0.015),a lower ejection fraction (54.22±0.91%, Δ –5.33%, p=0.009), but larger sizes of the leftatrium (4.66±0.06 cm, Δ +8.37%, p<0.001), slightly higher values of the height of the slopeof the ST segment (STH) of the differentiated ECG in the ischemiс zone (0.61±0.04 mm,Δ +17,31%, p=0.074) than in patients aged <60 years. Also, elderly patients, in comparisonwith the young and middle-aged group, are characterized by more hemodynamicallysignificant lesions of the coronary arteries with left circumflex artery occlusion. Women hada higher quality of life according to the EQ-VAS scale (66.91±2.43%, Δ +10.94%, p=0.050),lower heart rate (71.82±1.53 bpm, Δ –5.87%, p=0.082), higher values of total cholesterol(5.95±0.19 mmol/l,Δ+10.39%, p=0.038), erythrocyte sedimentation rate (16.67±2.19 mm/h,Δ +39.03%, p=0.068), lower hemoglobin values (138.00±2.29 g/l, Δ –7.64%, p<0.001),erythrocytes (4.65± 0.08 T/l, Δ –4.52%, p=0.045) and lower creatinine (97.01±4.43 μmol/l,Δ –10.74%, p=0.054), a higher ejection fraction (57.29±0.76%, Δ +4.82%, p=0.028),but smaller sizes of the left atrium (4.36±0.07 cm, Δ –4.39%, p=0.026), end systolicdimension (3.47±0.06 cm, Δ –10.80%, p<0.001), end diastolic dimension (5.05±0.07 cm,Δ –6.83, p<0.001), lower values of STH of the differentiated ECG in the ischemia zone(0.51±0.03 mm, Δ –16.39%, p=0.053) than in men. Also, for women, in comparison withmen, the damage of the right coronary artery is less common.Conclusions. Thus, changes in clinical, laboratory and instrumental indicators arecorrelated with age and sex, have a marker role in predicting the course of the disease,choosing methods on influencing risk factors and optimizing treatment, and the indicatorsof a differentiated ECG using the «Smart- ECG» software significantly improve thediagnostic opportunities.

This study aimed to study the intentions of Malaysian domestic travellers to visit Sabah after the COVID-19 travel restrictions were lifted by exploring the variables of fear of COVID-19, travel anxiety, subjective norm, perceived behavioural control, and risk attitude. This study utilizes the Theory of Planned Behaviour (TPB) to explore factors impacting travel intentions in a post-pandemic context. SPSS and Partial Least Squares Structural Equation Modelling (PLS-SEM) were used to analyse the 303 online survey respondents. The study reveals diverse perceptions among Malaysian domestic visitors regarding travel to Sabah after COVID-19 travel restrictions. Fear of COVID-19 and risk attitude were found to have no significant impact on travel intentions. However, perceived behavioural control, subjective norms, and travel anxiety showed significant relationships with travel intention. The findings offer practical implications for tourism stakeholders to develop targeted strategies for attracting and accommodating domestic travellers in Sabah while contributing to existing knowledge in the tourism and educational field. This study incorporated the TPB model by adding more variables, resulting in a more powerful explanation of post-pandemic travel intentions.

El ideal de tolerancia religiosa en la España ilustrada
Authors: Domínguez Juan Pablo
Published: December 2023

En la España del siglo XVIII, la labor de la Inquisición y la ausencia de minorías religiosas contuvieron la difusión de la idea ilustrada de tolerancia. No obstante, las críticas de escritores y políticos hispanos a la Inquisición y a las expulsiones de judíos y moriscos, la actitud de la prensa de Madrid ante los edictos de tolerancia de otras naciones europeas, los escritos de españoles exiliados en la Francia revolucionaria y las traducciones al castellano de textos favorables a la tolerancia evidencian que esa idea no fue tan ignorada al sur de los Pirineos como suele decirse.

The World in 2024: ten issues that will shape the international agenda
Authors:   Senior Research Fellow, CIDOB, Colomina Carme
Published: December 2023

2024 will be a year of ballots and bullets. The elections held in more than 70 countries will serve as a stress test for the democratic system, and the impact of the multiple conflicts stoking global instability will shape a world in the throes of a global power shift and a clear regression in terms of humanitarianism and fundamental rights. The erosion of international norms is more acute than ever, and events become more unpredictable. 2024 begins wide open, marked by an increasingly diverse and (dis)organised world, with hanging interests and alliances in issues such as geopolitical competition, green and digital transitions, or international security. The economic consequences of the succession of crises of recent years will be more visible in 2024: economic growth will be weak, and China’s downturn will reverberate in emerging economies, in a climate of rapid tightening of financial conditions and a strong dollar.
Influence of Biochar Addition to Nursery Container Media: Trace Gas Efflux, Growth, and Leachate N
Authors: Prior Stephen A. , Runion G. Brett , Murphy Anna-Marie , Hoffman Heath , Johnson Mark G. , Torbert H. Allen
Published: December 2023

Biochar is a pyrolytic product generated by heating biomass in the absence of oxygen such as during bioenergy production. Biochar can be made from various feedstocks and research into its potential use in agricultural systems has examined its effects on plant growth, trace gas emissions, and N loss. However, since a paucity of work has examined biochar use in horticultural container production systems, we investigated how biochar additions to growth media impacted trace gas efflux (CO2, CH4, and N2O), plant growth, and N loss via leachate in two separate experiments: a peat-based greenhouse study using viola (Viola cornuta L. ‘Sorbet® XP Deep Orange’) and a pinebark-based outdoor study using daylily (Hemerocallis x ‘EveryDaylily Cream PBR’ L.). Biochar had little effect on viola growth, but growth inhibition was noted for daylily. Both studies clearly showed that N in leachate was reduced by biochar additions, with higher biochar rates having greater effects on reducing N loss. Reductions in N loss with biochar suggest improved N use efficiencies in agricultural systems. Biochar use also decreased N2O and CO2 fluxes in daylily, which suggests that biochar could help mitigate global climate change. Our results suggest that future studies should focus on testing lower rates of biochar in terms of growth and environmental impacts. The complexities of N management highlight the importance of developing biochar practices that increase N retention for the benefit of both agriculture and the environment.

Species used in this study: viola (Viola cornuta L. ‘Sorbet® XP Deep Orange’); daylily (Hemerocallis x ‘EveryDaylily Cream PBR’ L.).
Effects of Insecticide Drench Application against Immatures of Systena frontalis in Container-grown Hydrangea paniculata
Authors: Joseph Shimat V. , Del Pozo-Valdivia Alejandro I.
Published: December 2023

Systena frontalis (F.) (Coleoptera: Chrysomelidae), commonly referred to as the redheaded flea beetle, is a serious pest in container nurseries, as adult feeding defoliates nursery crops and affects plant salability. Because the foliar application of insecticides provides inconsistent efficacy, additional and alternative control tactics are sought to target immatures of this pest in growing media. Thus, the objective was to determine the effects of non-neonicotinoid insecticides applied as a drench to growing media on immatures of S. frontalis. In 2021 and 2022, nine active ingredients were evaluated in four trials in a Georgia nursery and at a Virginia research and extension center. If available, the maximum label rates for flea beetles or other coleopteran pests were applied once to Hydrangea paniculata Siebold containers (11.4 L, 3 gal) as a drench application. The emergence of S. frontalis adults from treated growing media and foliar feeding damage was lower for the tetraniliprole (TetrinoTM) and spinetoram + sulfoxaflor (XXpire®) treatments than for nontreated plants. Cyclaniliprole (SarisaTM) and chlorantraniliprole (Acelepryn®) suppressed S. frontalis adult eclosion with less feeding damage than the nontreated plants. Tetraniliprole, spinetoram + sulfoxaflor, and cyclaniliprole are not labeled for drench application. Dinotefuran (Safari®) effectively reduced adult emergence and feeding damage.

Species used in this study: Redheaded flea beetle, Systena frontalis (F.); panicled hydrangea, Hydrangea paniculata Siebold.

Chemicals used in this study: Cyantraniliprole (Mainspring®GNL), chlorantraniliprole (Acelepryn®), tetraniliprole (TetrinoTM), cyclaniliprole (SarisaTM), Spinetoram + Sulfoxaflor (XXpire®), tolfenpyrad (Apta®), Chromobacterium (Grandevo®CG), flupyradifurone (AltusTM), dinotefuran (Zylam® Liquid, Safari® 20G), and polyterpenes pinene (NuFilm® P).
Percepción y significación de la gráfica urbana, en un acercamiento a la transdisciplinariedad
Authors: Olalde Ramos María Teresa
Published: December 2023

Se puede decir que los gráficos urbanos al ser analizados desde los distintos enfoques en que son interpretados, pueden ser entendidos como un fenómeno complejo, vistos desde su representación formal como signos, o también de acuerdo a su funcionalidad práctica como pueden ser las señales de tránsito, o bien los anuncios publicitarios y su impacto comercial que, como parte del contexto en que se ubican, pueden cambiar su sentido práctico y tomar nuevos roles de acuerdo a su significado. Estos mismos mensajes visuales pueden llegar a ser interpretados y significados como símbolos representativos de un sitio o como decoraciones escenográficas del mismo. Lo importante es entender es que todos y cada uno de los elementos visuales que encontramos en el contexto urbano comunican, ya que intrínsecamente llevan un mensaje en su propia representación visual, que a su vez son interpretados desde distintos enfoques por el sujeto con el que interactúan. El estudio transdisciplinario enriquecerá el conocimiento de la ciudad, lo cual puede ser un gran apoyo en la creación de distintas intervenciones en cuanto a la organización de espacios, desarrollo de edificaciones, de elementos mobiliarios, de transporte, así como de procesos de comunicación, las cuales se verán enriquecidas con los distintos enfoques disciplinarios que podemos encontrar en las diversas interpretaciones de los múltiples sujetos que la viven y la utilizan como parte de su cotidianeidad.
Ablepsia congénita. Condición humana para una semiosis
Authors: Zarur Cortés Jorge Eduardo
Published: December 2023

Las miradas que desde la discapacidad visual se dan, se vinculan –sin duda–, con la semiosis desde cierta acción, comportamiento o desarrollo que implica a los signos y su significado. La ablepsia congénita, como otra variedad perceptiva podría considerarse como una modalidad que tergiversa los conceptos visuales ante una reinterpretación de los acontecimientos. Sin embargo, también propone nuevas significaciones desde la subjetividad ante la realidad y/o la objetividad visual, conformándose otras realidades generadas ante la concepción de las cosas y del mundo en la indagación de los detalles de éstas y en el que la “vivencia” de las imágenes mentales se presentan para el ciego congénito como parte de sí o de otra realidad. Por lo tanto, ¿qué sentido le dan a los “signos” del entorno? y cómo estos son proveedores de información valiosa para concebir el ser y estar en un contexto en el que la oscuridad es permanente y la que los sonidos, olores, sabores y texturas lo orientan en lo no visual.
La teoría del homo ris capax (la risa como capacidad exclusiva humana) en Isidoro de Sevilla
Authors: Ruiz Nolo
Published: December 2023

En el vigesimoquinto capítulo del libro segundo de Etimologías, epítome de la Isagoge de Profirio, el filósofo hispalense Isidoro de Sevilla, tomando el ejemplo del pensador sirio, recoge la teoría antropofilosófica del homo risv capax, esto es, el humano definido como único ser vivo, mortal o inmortal, irracional o racional, capaz de reír. O lo que es lo mismo: la risa entendida como lo (más) propio –en el sentido de lo exclusivo– del ser humano. Una teoría que tiene una larga trayectoria en la historia de la filosofía antigua occidental hasta llegar al planteamiento del filósofo hispalense (y también tras él). El presente artículo presenta la propuesta isidoriana mostrando los antecedentes, tanto generales como específicos, en torno a la cuestión de la risa y de esta como propiedad singular y distintiva humana, así como una delimitación del sentido expuesto en el pensamiento y obra de Isidoro de Sevilla, junto con las diferencias existentes entre las del pensador sevillano y sus precedentes filosóficos, esto es, sus aportaciones específicas.
Sobre el problema de la libertad en la modernidad
Authors: Leiva Bustos Javier
Published: December 2023

Con el auge y desarrollo de la revolución científica europea a partir de los siglos XVI y XVII, que terminaban por liquidar la física y teleología aristotélicas para reducir la visión del mundo a una relación eficiente entre causas y efectos, entraba también en crisis uno de los presupuestos fundamentales en la metafísica y ética occidentales: la cuestión de la libertad humana. Al fin y al cabo, si toda la naturaleza física estaba sometido a causas necesarias, universales e inquebrantables, a las que nada puede escapar, y el ser humano era también un cuerpo inserto dentro de esa naturaleza, ¿por qué no iba a estar él igualmente determinado? A lo largo del presente artículo trataremos de presentar lo que la irrupción de la modernidad supuso a propósito del debate acerca de la libertad de la voluntad —comúnmente denominada «libre arbitrio»—; cómo la figura de Hobbes, a raíz de la filosofía cartesiana, se erige como un representante del determinismo materialista —aunque no el único—; y la solución al dilema que ofrece Kant con el conocido postulado de la libertad.
Diagnosis of inter-turn short circuit fault in IPMSMs based on the combined use of greedytracking and random forest
Authors: Wang Jianping , Ma Jian , Meng Dean , Zhao Xuan , Zhang Kai , Liu Qiquan , Xu Kejie
Published: December 2023

Inter-turn short circuit (ITSC) is a frequent fault of interior permanent magnet synchronous motors (IPMSM). If ITSC faults are not promptly monitored, it may result in secondary faults or even cause extensive damage to the entire motor. To enhance the reliability of IPMSMs, this paper introduces a fault diagnosis method specifically designed for identifying ITSC faults in IPMSMs. The sparse coefficients of phase current and torque are solved by clustering shrinkage stage orthogonal matching tracking (CcStOMP) in the greedy tracking algorithm. The CcStOMP algorithm can extract multiple target atoms at one time, which greatly improves the iterative efficiency. The multiple features are utilized as input parameters for constructing the random forest classifier. The constructed random forest model is used to diagnose ITSC faults with the results showing that the random forest model has a diagnostic accuracy of 98.61% using all features, and the diagnostic accuracy of selecting three of the most important features is still as high as 97.91%. The random forest classification model has excellent robustness that maintains high classification accuracy despite the reduction of feature vectors, which is a great advantage compared to other classification algorithms. The combination of greedy tracing and the random forest is not only a fast diagnostic model but also a model with good generalisation and anti-interference capability. This non-invasive method is applicable to monitoring and detecting failures in industrial PMSMs.

Published: December 2023

Objective. Adipose tissue is considered to be an endocrine organ that secretes bioactive substances known as adipokines that contribute to the pathophysiology of metabolic and coronary diseases related to obesity. In this study, various novel biomarkers, such as inflammatory markers that are pro-inflammatory (visfatin) and anti-inflammatory (omentin-1), as prognostic indicators for people with coronary artery disease (CAD) were investigated.

Methods. In this study, 30 diabetic patients with CAD, 30 diabetic patients without CAD, and 30 healthy control counterparts were included. Serum omentin and visfatin concentrations were evaluated by solid-phase enzyme linked immunosorbent assay (ELISA) kit. Patients with established diagnosis of CAD based on angiography, ECG, and elevated cardiac marker level were included into the study. Patients with cardioembolic stroke, cerebral venous sinus thrombosis, CNS vasculitis, and hemorrhage due to trauma, tumor, vascular malformation, and coagulopathy were excluded.

Results. The serum omentin-1 levels were significantly higher in the healthy controls in comparison with the diabetic group (p<0.0001) and serum visfatin levels were significantly higher in the diabetic group in comparison with the healthy controls (p<0.0001). The serum omentin levels were significantly higher in the diabetic group in comparison with the cardio-diabetic group (p<0.0001) and serum visfatin levels were significantly higher in the cardio-diabetic group in comparison with the diabetic group (p<0.0001). The serum omentin-1 showed negative correlation with the serum visfatin in the cardio-diabetic group.

Conclusion. The adipokines, such as omentin and visfatin, may be good therapeutic candidates in preventing or ameliorating CAD.
Der Glaube kommt vom Hören. Das Modell des Salzburger Evensongs als gesungene Form der Verkündigung
Authors: Rettenbacher Sigrid
Published: December 2023

While the number of churchgoers has constantly been going down in the last years, an interesting observation can be made: The number of people attending choral evensong has significantly increased in the last decades. Not only believers, but non-believers as well are overwhelmed by this form of liturgy based on the singing of the choir. This article describes the project of Salzburg’s Evensong, an adaption of the Anglican choral evensong for the German-speaking context of catholic or protestant parishes. Based on the theological awareness that faith comes from hearing, the project focuses on the insight that singing is a way of proclamation as well. Thus, Salzburg’s Evensong offers an attractive liturgical format that has an ecumenical dimension and pays attention to the aesthetic aspect of faith.

Authors: Talabi Henry
Published: December 2023

The mechanical behaviour of Al6063 alloy matrix composites reinforced with rice husk ash (RHA), silicon carbide (SiC) and copper nanoparticles (CuNP) has been investigated. Rice husk ash and silicon carbide mixed in fixed weight ratios of 3: 1 while copper nanoparticles were varied from 1 to 4 weight ratio to prepare hybrid reinforced Al6063 based composites using two-step stir casting and spin casting technique. Hardness measurement, tensile testing, impact toughness, optical and scanning electron microscopy were used to characterize the composites produced. It was observed that as the density increases with the increase in addition of copper nanoparticles, the porosity reduces. It was also observed that hardness increases with increase in copper nanoparticles addition. The ultimate tensile strength and impact toughness increased with increase in copper nanoparticles. The impact toughness of reinforced composites improved with increase in copper nanoparticles addition. The composition with 4 wt. % copper nanoparticles exhibited superior combination of properties that may be useful for design of components for automobile application.

High mechanical and temperature cyclic loading of the final products for automotive, transport, construction and agriculture mechanization industry, demands sufficient mechanical properties of all of their components during its exploitation. Majority of the components is made of steel, by different cold forming processes. Their main demanded characteristics are surface wear resistance and fatigue strength under pulsating stress in combination with cyclic temperature loading, which could be achieved only by appropriate heat treatment. The efficiency of the combined inductive heating and water quenching heat treatment and quality of the planetary shafts were analyzed, with the use of thermographic analysis, hardness measurements, and metallographic examination. Combination of inductive heating and water quenching is the most effective heat treatment process of carbon steel planetary shafts for the diesel engine starters. Long life span of carbon steel planetary shafts it’s essential for their economical production. The replacement of starter is expensive from both: money and working time point of view. Surface temperature measurements during the inductive heating process were performed in the industrial environment. The intensity and homogeneity of the planetary shaft surface temperature field was measured by thermographic camera. On the base of theoretical knowledge and measurements, a mathematical model for temperature conditions determination in the shaft during the entire process of heating and quenching was carried out, and used for analyses and optimization of planetary shafts induction hardening process.
On Photonic Implementation of Quantum Computers

Published: December 2023

The first section of the work investigates light modes as a means of implementing optical qubits and qudits. The modes considered are polarization mode, path mode, transverse spatial mode, frequency mode, temporal bin-mode and temporal mode. Subsequently, mathematical model of linear optical elements like beam splitters (BS) and phase shifters are deduced and their capability of representing any single qubit optical gate is exposed. Finally Knill, Laflamme and Milburn (KLM) method of using linear optical elements to promote nonlinear operations based on nonlinear (nondeterministic) sign-flip gate (NS) is explained, and designs of two qubits conditional sign flip gate (c-z1/16) and CNOT gate, both based on KLM method, are demonstrated. So, universal set of quantum gates based on linear optics is possible.

This paper presents an analysis focused on the stress-strain dynamics within the forward extrusion process for hollow elements. The forward extrusion of hollow elements is characterized by extensive plastic deformation and complex material flow. This process involves splitting the metal continuum, subjecting it to plastic deformation, and merging it into a seamless product with a predetermined cross-sectional shape as it exits the tool. Employing modern numerical finite element methods is essential for designing such processes, as it enables the simulation of metal behavior within the tool. These simulations help predict mechanical parameters within the deformable material continuum, such as stress, strain, temperatures, and strain rates. Additionally, they allow for the optimization of tool designs tailored to the specific product, improving process efficiency and quality. Understanding the stress-strain distribution at individual nodes enables proactive measures to prevent mechanical disruptions within the continuum, ensuring the integrity and quality of the final product—an essential criterion in the forward extrusion process for hollow elements.
ARTISTS AT WAR
Authors: ANGHEL Silviu , ZBUCHEA Alexandra
Published: December 2023

At least since Antiquity, art and war have interfered. The most common aspect to consider is the propaganda associated with it. At the same time, artists took a stand for/against certain wars (or the concept of war) according to their personal values, beliefs, and experiences. The first part of the paper investigates how arts, war, and propaganda intertangled during the past two millennia. The Second World War, the most complex one to this date with globally diverse implications, seems to prove most how important artists are involved in times of war. This paper investigates how artists reacted to war and propaganda during the past two millennia. It includes a case study that analyzes the Russian aggression in Ukraine through the eyes of various artists. It follows how Russian, Ukrainian, and foreign artists responded to this shocking event. As expected, many Russian artists are supporting the war, on various grounds: they fear negative consequences, they believe the official perspective and propaganda, etc. Nevertheless, Russian artists – still living in Russia or who left the country immediately after the beginning of the war in Ukraine – are an important opposition voice despite the risks they take to express their views. It is even more relevant since the common political lines of action seem not to be possible in present-day Russia. As expected, most Ukrainian artists are publicly expressing their opinions against the war. Their art has benefited from wider attention than previously, especially in the EU, where many of them live as refugees of war, and in the US. The internet is, as expected, an important platform that gives voice to artists and allows the wide distribution of their work. In this facilitating framework, memes are also flourishing and getting viral, informing about and influencing attitudes to the war. The investigation also identified numerous foreign artists who took a public position, in most cases for Ukraine, especially in the first months of the war. The way artists reacted and related to the war, both on the Russian and the Ukrainian side, shows the complex relationships society and, above all, the arts have with war. In arts, as in society, war is both hated for its suffering and praised as a feat of patriotism.
GEOPOLITICAL VIEWS AND GEO-ECONOMIC CONSIDERATIONS ON THE GERMAN STRATEGY AND EU WIDER FRAMEWORK RELATIONS WITH CHINA
Authors: MUNTEANU Bogdan
Published: December 2023

On July 13, 2023, the German Government has released the first national strategy related to approaching China in international relations, including from a geo-economic perspective. The text of the German strategy is of significant importance for other EU member states and the EU authorities, as it encloses aspects pertaining to the industrial policy and cyber-security, serving nonetheless as a use-case and / or a model for developing a coherent approach to China, including the perspective of economic diplomacy in the larger context of policy dialogues with China. From a diplomatic stance, China has anchored international relations in the countries of Central and Eastern Europe, some of which being EU members – in 2012, China forged partnerships via the “16+1” Cooperation, later extended after the Dubrovnik Summit to “17+1” by the adhesion of Greece. China looks to consolidate bilateral relations in Europe via a multi-level approach and sectorial-specific coordination (to include trade, energy, financial technologies, forestry, maritime services, etc) and the German strategy complements the projected EU-China comprehensive strategic partnership, rather than to be an alternative to it. In this context, the paper explores the implications of the German strategy towards China from the European viewpoint and analyses its value-added potential to supporting the wider angle of EU international relations towards China. The research hypothesis is that in the current international geopolitical context related to China, the German strategy enhances at the national level the guiding principles of EU approach to managing the relations with China and adds value to EU economic diplomacy instead of duplicating it. The research methodology is focused on a qualitative analysis of documented authentic scientific public resources and synthesis of key aspects from a geopolitical and geo-economical wide angle of Sino-European relations. The conclusions draw on the fact that China acts as an international challenger, on a path to consolidate its international role and the EU and the German strategies towards China support the mitigation of exposures to economic dependencies by de-risking linkages rather than economic de-coupling from “a partner, a competitor and a systemic rival” at the same time, as designated by EU.

The opportunities of the educational process can be expanded through the use of innovative mechanisms. The aim of the work is to determine the effectiveness of teaching as a result of the implementation of the Visual Mind Mapping strategy to improve students’ foreign language competence. The aim was achieved using the general theoretical method of comparison, calculation of the concordance coefficient, the efficiency coefficient, the Whitney-Wilk test. Learning was ensured through the development of educational mechanisms, which consisted in the visualization of information and the development of intellectual activity. The study of new words, the use of digital technologies (Writer, Rosetta Stone, Busuu), the development of communication skills, and the development of professional skills were also provided. It was found among students that the use of Visual Mind Mapping contributes to obtaining a high level of knowledge in a shorter time. Focusing on Kirkpatrick model made it possible to establish that the majority of students acquired a high level of foreign language competence after testing their knowledge. The students have a positive attitude to learning using Visual Mind Mapping. The practical significance of the article is the possibility of involving innovative technologies for learning a foreign language. The prospects of further research are to compare the effectiveness of learning with the use of Visual Mind Mapping for junior and senior year students.

Poetic Space of Intimacy and Movement
Authors: De Sanctis Olivia
Published: December 2023

This paper explores the transformation of poetic blank space in the work of three contemporary poets: Carolyn Thompson, Sonja Johanson, and Lisa Huffaker. Specifically, Thompson's Actions Speak Louder Than Words, and The Eaten Heart, Johnson's Untitled Erasure poem series, and Huffaker's 6 Images are compared and contrasted for their unique approaches to using the space of the page to add to the reading experience. The works discussed by each poet are erasure works that transform the page's white spaces surrounding the poem, using various additive or reductive methods to reimagine this space. If the white spaces surrounding a poem are often read as silences or voids, then using multi-modal techniques, these three poets transform these spaces in ways that signal intimacy and movement instead. This creation of intimacy and movement is explored through the intertextual jesters, an essential aspect of erasure poetry, along with the intersections between poetry and sculpture, bodily interactions with and implications within the texts, and poetry and avant-garde notions of cartography.
"Sketch", "What it takes to keep the mind going" and "Drag(a) de mama"
Authors: Burghelea Clara
Published: December 2023

These poems address the manner in which white space lives in harmony with words or in the margins/ in between the lines of the poems. A good portion of meaning is found outside the written words; together with line breaks they teach the reader how to read the poems out loud and inside their minds. In these poems, white space plays several roles: it is a stylistic technique, it asks the reader to actively read the poem, and it visually creates an aesthetic.
