El pensador Domingo Faustino Sarmiento, como presidente de Argentina, era dela idea que había que poblar aquellas tierras de Suramérica, pero no de negros ni de indios, sino de europeos, especialmente de obreros calificados y de hombres blancos con una cultura superior. Por eso su principal lema era: “Gobernar es poblar en el sentido que poblar es educar, mejorar, civilizar, enriquecer, engrandecer, espontánea y rápidamente como ha sucedido en los Estados Unidos”.
Aproximación a los principios éticos de liberación del sujeto latinoamericano en el pensamiento de Enrique Dussel
Authors: Leones Ortega Enrique
Published: March 2024

Con esta disertación nos proponemos reflexionar en torno a los principios éticos que fundamentan la praxis de liberación del sujeto latinoamericano en el marco del pensamiento filosófico de Enrique Dussel. Para ello se consideran, en primer lugar, aspectos biográficos del autor en cuestión y la importancia de su obra, así como los orígenes y desarrollos de su pensamiento ético en la tradición filosófica que le sirve de contexto generacional. Seguidamente, se determinan las relaciones entre los fundamentos y principios de la ética de la liberación con la tradición de las éticas materiales, y sus desafíos ante otras tradiciones de pensamiento ético, además que se puntualiza en los criterios que aporta la ética dusseliana de la liberación, como lo son: el complejo sistema categorial filosófico, el método analéctico de pensamiento y una cartografía de los problemas de la realidad ética contemporánea. Finalmente, se plantean algunas consideraciones en torno al sujeto latinoamericano en el marco de la situación mundial paradójica de globalización/exclusión de las grandes mayorías de la humanidad.
La acción colectiva feminista ¿De la lucha de clases a la lucha de géneros? Aportes para la comprensión práctica de los movimientos sociales: el caso Ni Una Menos
Authors: Castro Riaño Luis Carlos
Published: March 2024

En este artículo me propongo elaborar una explicación factible de los movimientos sociales contemporáneos considerando la acción colectiva feminista del caso argentino “Ni Una Menos” y cuatro componentes visibles en ella: el estructural, el político, el estratégico y el cultural. Para ello incorporo algunas perspectivas de las diferentes teorías de la movilización social; repaso los postulados centrales del feminismo materialista francés, la teoría queer y el feminismo decolonial; y reflexiono sobre las estrategias de la movilización, los repertorios de acción y los marcos de la movilización,haciendo énfasis en las gramáticas de la vida pública que se implementan en estos últimos. El texto presentado tiene por objetivo reforzar el vínculo entre la comprensión y práctica de la protesta social.
Danzar la palabra con los gameranos: ¿de quien es el etnoconocimiento de la conquista?
Authors: Arizmendi Bedran Manuel Francisco
Published: March 2024

Este artículo tiene como propósito presentar los modos en los que la Danza de la Conquista en los Gameranos se convierte en un espacio de etnoconocimiento cuyos alcances y posibilidades se extienden más allá de los marcos propios de lo musical y lo coreográfico para situarse en la herramienta fundamental para transmitir saberes acerca de lo natural, lo medicinal y las formas de entender lo real y lo simbólico. Así mismo, a partir del análisis de la dinámica histórica, se busca plantear de manera precisa el alto riesgo de pérdida del profundo acervo epistémico que se encuentra en la danza con la aparición de fenómenos de violencia y apropiación cultural que ponen en peligro el inmenso legado que representa la palabra hecha vida en la Danza de la Conquista. Para poder dar cuenta de estos dos aspectos, a partir del ejercicio reflexivo propio de la fase diagnóstica de un trabajo doctoral en curso, este texto realiza una revisión histórica de los procesos propios del origen y surgimiento de la danza para luego establecer un paralelo crítico con esos riesgos que corre el legado cultural de los habitantes de Gamero tanto por la sombra del conflicto de nuestra nación como por el desvanecimiento del etnoconocimiento presente en las prácticas medicinales, cosmogónicas y simbólicas que se sintetizan en el acto dancístico más allá de la dimensión coreográfica.
Karl Popper y la crisis de la democracia en América Latina
Authors: Arteta Ripoll Cristóbal
Published: March 2024

El famoso autor de Las sociedades abiertas y sus enemigos, Karl Popper, nos permite con los postulados teóricos de su racionalismo crítico analizar las tendencias del pensamiento económico, sociológico y político que intentan implementar un “neo corporativismo, dudosamente democrático”, en la era de la globalización, contrario a una de las tesis del pensador vienés de mantener y fortalecer las democracias como característica central de las sociedades abiertas. Ello en el marco de las nuevas circunstancias mundiales, creadas por la hegemonía globalizadora, tales como: la caída del socialismo real, la crisis de las ideologías, la debilidad de las políticas de izquierda, la desmovilización del sindicalismo y el gran entusiasmo que despierta, aunque diezmado, la agenda neoliberal alrededor del libre mercado. La gran importancia de Popper radica en articular debidamente su concepción epistemológica con el discurrir de la política y sus tendencias democráticas y totalitarias en el mundo contemporáneo. A los intelectuales, si son demócratas, les corresponde defender la esencia de la democracia que no es otra cosa que la “soberanía o poder soberano del pueblo”, soportando todas las dificultades e inconveniencias que se deriven de su accionar en la vida política.  A pesar de sus críticas a la oligarquización partidista, y de la tendencia intelectual a rechazar y atacar los partidos, dice que es conveniente soportarlos por la necesidad de su existencia para la democracia. Sus planteamientos en el plano científico y político tienen hoy una singular importancia para entender y comprender las complejidades del mundo científico y político.
Representación de fronteras, límites y seres del otro mundo en Chambú (1946) de Guillermo Edmundo Chaves
Authors: Uscategui narvaez Alexis francisco
Published: March 2024

El presente trabajo reflexiona la novela Chambú (1946) de Guillermo Edmundo Chaves. El mismo da cuenta de la representación de fronteras, límites y seres del otro mundo, cuyas enunciaciones cumplen un rol clave dentro de la literatura colombiana. En esta dimensión, a través de un método hermenéutico, se estima alcanzar resultados de sumo impacto, debido a que, por un lado, este tipo de análisis no son comunes y requieren de una nueva mirada; por otro, permitirá al mundo académico y al público en general, conocer acerca de las cosmovisiones y devenires culturales afincados en la frontera colombo-ecuatoriana. En suma, se pretende desacralizar aquellos cánones que han considerado que este tipo de representaciones son deleznables para la cultura. De ahí que es importante demostrar que dichas figuraciones permiten que la sociedad se mueva de manera distinta, de cara a hilvanar nuevos esplendores narrativos.
Intuición, racionalidad y acción
Authors:   Universidad Católica del Maule, Miranda Rafael
Published: March 2024

Durante los últimos cinco años, un tema principal de discusión en el área epistemológica ha sido el rol de las intuiciones como una guía confiable para el conocimiento, o como una forma de justificación de alguna creencia. Se asume que si no existe tal función de las intuiciones (intuiciones racionales específicamente), entonces son gratuitas, irrelevantes y una guía poco confiable para el conocimiento o la creencia. El papel de las intuiciones en el área práctica no simplifica el problema: si un sujeto (S) toma una decisión fundado (incluso parcialmente) en algunas intuiciones, entonces es difícil negar la relevancia de ellas en esta arista práctica. Por lo tanto, surge el dilema: ¿cómo puede una intuición guiar la acción de un sujeto S, si S ni siquiera está justificado en tener esa intuición? Para responder a esta cuestión, propongo una defensa híbrida (a priori - a posteriori / teórica - práctica) de la intuición racional (IR), a través de dos roles (diferentes de los roles probatorios o justificatorios): un rol propedéutico (también llamado rol ejemplificador contrafactual) y un rol de guía de la acción en la toma de decisiones. Al mismo tiempo, se afirma que una IR tiene un rol de transmisor (diferente del rol justificatorio) que es relevante con respecto al vínculo inferencial entre premisa-conclusión. Se discute una conexión similar sobre el nexo concebible-posible. De esta manera, se propone un racionalismo moderado, que sostiene la falibilidad de IR, la relevancia de la evidencia a posteriori y la confiabilidad a priori.
Inmaterial Matters, or the Unconscious of Materialism: A Conversation with Elizabeth Grosz
Authors:   Universidad Adolfo Ibáñez, Mercier Thomas Clément
Published: March 2024

In this conversation, which took place across several months in the year 2021, Elizabeth Grosz describes her position with respect to “new materialism” and “the material turn”: while she emphasizes the necessity of materialist thought in the current situation marked by a global pandemic, she also stresses the equal importance of what she calls “the incorporeal”: an excess in and of matter, materiality’s heterogeneous virtuality, differentiality and becoming-other. Grosz describes the incorporeal as mutually implicated with materiality in a way that eschews both monism and dualism. The conversation roughly follows five topics: 1. How does one conceive of ontology without fixity? 2. How does matter “make sense”? 3. Can we think sexual differences beyond cisgender binarism and oppositional dualism? 4. What are the ethico-political implications of a materialist thought predicated on becoming and immanence? 5. Is psychoanalysis compatible with materialism, and is there a materiality of the unconscious? In the course of this exceptional interview, Grosz discusses the works of Jacques Derrida, Donna Haraway, Sigmund Freud, Luce Irigaray, Karen Barad, Friedrich Nietzsche, and of course Gilles Deleuze, among many others...
Monismo prioritario, relaciones internas y libertad modal
Authors:   Universidad de Santiago de Chile, Briceño Sebastián
Published: March 2024

Schaffer ha argumentado que la prioridad ontológica del cosmos puede ser inferida a partir de la ausencia de la libertad modal de sus partes. En este artículo ofrezco razones en contra de las siguientes premisas de su argumento: (i) el supuesto según el cual los objetos fundamentales gozan de libertad modal, y (ii) el supuesto según el cual los objetos que están en la relación de ser compañeros de mundo, dada la teoría de contrapartidas, carecen de libertad modal.
Bajo el signo del Demogorgon: Inmanencia y relación en Lampas Triginta Statuarum de Giordano Bruno
Authors:   CONICET, Benvenuto Rodrigo Miguel ,   LICH,   UNSAM
Published: March 2024

Nuestra investigación indaga sobre las posibilidades de establecer una lectura ontológico-relacional de la obra de Giordano Bruno, a partir de “La lámpara de las treinta estatuas” (Lampas triginta statuarum). La particularidad de esta obra, escrita en Wittenberg en 1587, reside en la exposición de la producción ontológica de las modalidades que surgen a partir de la relación entre lo infinito y lo finito por medio de estatuas o representaciones figurativas. Nuestra hipótesis consiste en exponer la matriz ontológico-relacional del pensamiento bruniano y la riqueza expresiva de las modalidades que se reflejan a partir del concepto de relación y su representación figurativa bajo la figura del Demogorgon. En efecto, consideramos que se trata de una clave de interpretación factible para comprender la complejidad de los vínculos entre trascendencia e inmanencia en el pensamiento filosófico de Bruno. Para ello, analizaremos en primer lugar los conceptos que componen la tríada Alma del Mundo, Espíritu e Intelecto Primero, tal como se exponen en Lampas triginta statuarum. Luego exponemos el entramado relacional de estos conceptos con el objetivo de enfatizar los aspectos fundamentales de la inmanencia en la obra de Bruno. Por último, abordamos la noción de relacióncomo categoría que permite unificar los distintos aspectos de la inmanencia en la cosmología bruniana a partir de la figura mitológica del Demogorgon.
A Footnote on Alain Badiou´s Critique of Plato´s Sophist
Authors:   Independent Researcher, Murillo Moya Keylor
Published: March 2024

In his second book on being and event, Logics of Worlds, Alain Badiou describes Plato’s late dialogue, The Sophist as “one of the first transcendental inquiries in the history of thought”. In this dialogue, Plato introduces what he calls the Idea of the Other, the possibility of a being of non-being, an inevitable break with the Parmenidean tradition. However, according to Badiou, Plato fails to provide an example of how this Idea of the Other can manifest itself or be effective in a world, or in other words, appear. This paper argues that not only there is such an example in Plato’s Sophist, namely, the phantasma, but also that it can be strongly related to Badiou’s philosophical system.
Entre Ortega y Heidegger: En torno a la pregunta por la técnica
Authors:   Universidad de Chile, Alarcón Cid Nicolás
Published: March 2024

En el presente escrito se considera una interrogante planteada por Heidegger en la pregunta por la técnica (Die Frage nach der Technik), vale decir, la pregunta por una determinación esencial de la técnica, en relación con los planteamientos orteguianos sobre ella. Específicamente, intentaremos abordar una cuestión que Acevedo (1997) insinúa en su introducción a la pregunta por la técnica, vale decir, si es que acaso las reflexiones de Ortega sobre la técnica —especialmente por su marcada consideración en relación con la vida humana como proyecto— se quedan en el plano de una mera determinación correcta —como relación medio-fin antropológica— o bien podrían eventualmente trascender dicho esquema en favor de un tratamiento fenomenológico que vincula la técnica con lo más hondo de la existencia del hombre.
Le corps vécu n´est past un corps propre: Beauvoir ou l´apparition du corps dans "Le deuxiéme sexe"
Authors:   Aix-Marseille Université, Lorelle Paula ,   Archives Husserl de Paris
Published: March 2024

Dans Le deuxième sexe, Beauvoir affirme que « la femme, comme l’homme, est son corps : mais [que] son corps est autre chose qu’elle ». Apparaît dans cette phrase, comme dans l’histoire de la phénoménologie, l’espace d’une déhiscence au sein du corps vécu. Être son corps n’impliquerait pas que le corps soit entièrement soi – et le corps vécu, dès lors, ne serait plus un corps propre. D’où la question que nous tâcherons ici de déployer : l’aliénation au sein du corps vécu n’est-elle pas la condition même de sa manifestation comme corps matériel ? Nous tâcherons, dans un premier temps, de remonter à la source du concept de « corps propre » (Leib) chez les postkantiens, afin de montrer que le corps n’apparaît comme « propre », dans l’histoire de la philosophie, qu’en disparaissant comme « corps ». Ce qui nous conduira, dans un second temps, à interroger la (ré-) apparition du corps dans Le deuxième sexe, et plus précisément dans la description que Beauvoir fait du cycle menstruel.
The materiality of experience. Phenomenology between phainology and phenomenism
Authors:   Villanova University, Popa Delia
Published: March 2024

In this paper, I consider the materiality of experience as stemming from a temporal process of sense-formation (Sinnbildung), whose essence is not just formally configured, but also materially organized. In order to understand this process of sense-formation, I first examine the materiality that is intrinsic to the intentional sense and its relationship with the sensible materiality of experience brought forth by the project of hyletic phenomenology. In the second part of the paper, I propose to overcome the tension between a materiality of sense and a materiality of sensibility by reflecting on the specific materiality that is created in our experience through the dynamism of imaginative modifications. Allowing us to switch between different temporal and spatial horizons, imaginative projections and reveries reveal a hidden “reverse” side of our perceptive field, that we access only when we let go of objectifying acts and established significance. In the last part of the paper, I turn toward bodily gestures, in which I see an expression of experience that resists objectification and straightforward symbolization, attesting for the complex social inscription of our bodily existence. I end the paper with an inquiry into the specific materiality of gestures, understanding them as vanishing archives offered to the future.
Le réel comme matiére dans le premier enseignement de Jacques Lacan
Authors:   Husserl-Archives, Braga Pietro ,   KU Leuven
Published: March 2024

Les premiers Séminaires de Jacques Lacan (1953-1959) offrent une élaboration systématique des notions de l’Imaginaire et du Symbolique, mais font référence de façon seulement sporadique à la notion du Réel. Malgré la rareté des références, la conception du Réel que l’on peut en déduire est précise et cohérente, et confirmée par les séminaires successifs – au moins jusqu’au Séminaire XI (1964). Le Réel est à comprendre comme une matière indéterminée qui, tout en pâtissant du signifiant, lui résiste. Ceci constitue une innovation, de la part de Lacan, par rapport au concept philosophique classique de la matière (du moins tel qu’on le trouve chez Aristote, pour qui la matière n’offre aucune résistance à sa propre mise en forme) et prépare la base pour la théorie de l’objet a en tant que signifiant de la castration du sujet opérée par le langage, telle qu’elle est élaborée à la fin du Séminaire VI (1958-1959) et dans le Séminaire X (1962-1963).

Published: March 2024

An alternative to monopiles to support offshore wind turbines is the use of jacket structures founded on suction buckets. These foundations have been successfully deployed in recent developments and have proven to be a viable foundation concept due to their relatively fast and low-noise installation, as well as their general applicability for a wide range of soil conditions and suitability in deeper waters. However, the behaviour of bucket foundations subject to both short- and long-term uplift loading in coarse-grained soil remains an area of ongoing research. For the centrifuge testing in this project, offshore soil was provided from an Asian site – and the combination of silt size particles, water pore fluid and faster loading rates was used to replicate the drainage conditions during the loading of a full-scale bucket foundation in sand. Initial self-weight penetration of the skirts was followed by suction installation, with in-place testing then undertaken to explore both monotonic and cyclic performance. This paper presents results from the pilot testing, including the foundation response to cyclic (storm) loading applied symmetrically around an average uplift load.
Retos del sector social de la economía en México: individualismo, desconfianza y dependencia
Authors:   Universidad Politécnica de Atalcomulco, Blas-Yáñez Sandra
Published: March 2024

Las asociaciones locales de producción rural (alpr) son entidades reconocidas como parte del denominado sector social de la economía en México. Sin embargo, su seguimiento, evaluación y fortalecimiento es nulo, ya que, en términos de atención institucional y académica, dominan las sociedades cooperativas como figuras de organización empresarial solidaria más estudiadas. Por ello, el objetivo de este trabajo es determinar la compatibilidad de las acciones de una asociación local de productores de pulque en el centro de México con los principios de la Economía Social y Solidaria (ess). El estudio tiene un enfoque cualitativo de tipo descriptivo y exploratorio. Los resultados son producto de un diagnóstico situacional, elaborado a partir de observación participante, grupos de discusión, entrevistas semiestructuradas, revisión de archivo administrativo. Los ha-llazgos muestran que las prácticas de la alpr distan de los principios cooperativos, al persistir una cultura or-ganizacional de individualismo, desconfianza y paternalismo, que influyen negativamente en la capitalización de las inversiones, capacitaciones y vinculaciones de la asociación. Se concluye que, para impulsar economías alternativas, se requiere atender el desafío de concientizar sobre los principios y prácticas de la ess, bajo un programa de transformación cultural organizacional que permita superar la dependencia paternalista que constriñe la asociatividad en México.

The Mediating Role of Teachers’ Attitudes toward Instructional Supervision in the Association between Instructional Supervisory Practice and Teachers’ Job Performance
Authors: BERHANU Kelemu Zelalem
Published: March 2024

The school needs to pay instructional supervision considerable attention to implement better teaching-learning procedures that will result in a more effective education. These procedures ought to remain democratic and cooperative. The attitude of the teachers toward supervision influences the outcomes of the supervision process. Therefore, in the context of secondary schools in Ethiopia's Dembecha area, this study sought to explore the mediating effect of teacher attitude to instructional supervision in the relationship between job performance and instructional supervisory practice. A mixed research design that was convergent parallel was utilized. Using comprehensive sampling, all four principals, two secondary school supervisors, and three hundred teachers participated in the study. Consequently, the study discovered that although teachers' work performance was at a moderate level, the status of instructional supervisory practice and their attitudes about it were at a low level. There were positive, significant, and moderate levels of correlation between instructional supervisory practice, teachers' attitudes toward instructional supervision, and teachers' job performance. Finally, the study revealed that teachers' attitude toward instructional supervision has a mediating impact on the association between instructional supervisory practice and job performance. In terms of practical applications, this study supports educators and school administrators in recognizing the benefits and drawbacks of instructional supervision and in implementing corrective actions to address the issues secondary schools encounter. Secondary schools’ instructional supervision practices need to be improved further to be widely accepted by teachers and put into practice.

This research aims to examine the potential mediating role of lifelong learning motivation in the relationship between virtual risk perception and digital well-being of (whom?). With a view to filling the gaps in the literature, this study examined how lifelong learning motivation can play a mediating role in understanding the effects of the risks individuals perceive in digital environments on their digital well-being. The findings of the research, obtained within a theoretical framework that combines psychological, educational, and digital technology perspectives, aim to shed light on new studies on improving individual well-being in the digital world and make a significant contribution to better understand the complex dynamics of the digital age and to properly maintain individuals’ digital experiences. 140 people participated in the research. The research data was obtained by survey. In the 4-section questionnaire, the other sections except demographic information were obtained with the Virtual World Risk Perception (VWRP) Scale, Lifelong Learning Motivation (LLM) Scale and Digital Well-Being (DWB) Scale. Mediation analysis was performed on the obtained data with JAMOVI software. As a result of the analysis, it was determined that lifelong learning motivation fully mediates the relationship between virtual risk perception and digital well-being.
Evaluating mangrove conservation with the land management intervention equation based on selected cases from Indonesia
Authors: Walter Timo de Vries
Published: March 2024

Mangrove wetlands serve multiple ecological functions, such as carbon sequestration. Yet, at the same time, they are also suffering from poor and non-transparent restoration and preservation management, resulting in unnecessary losses. This article assesses how and where responsible land management can address this problem based on three different cases in Indonesia. It evaluates the cases through the lens of a descriptive and normative land management analytical framework of (de Vries 2021) with the equation form (∆LM = f(∆G, ∆L, ∆S, ∆E, ∆P, ∆B), The goal of the evaluation is to evaluate to how and to which extent major land interventions and mangrove preservation activities could align, and with which particular land management aspects improvements in this relation should start. The findings demonstrate that the alignment should begin with a more comprehensive and systematic pre-evaluation of possible impacts and effects, for all aspects which are changed by the intervention. Relying on a framework of responsible land management could support a better preservation of coastal mangrove areas.

Published: March 2024

Purpose: Post COVID Syndrome (PCS) is one of the most intriguing topics related to coronavirus disease 2019 (COVID-19). Fatigue is one of the most prevalent and disabling symptoms of PCS. In this study, we aimed to investigate the neuromuscular junction functions in people who have had long-term fatigue due to COVID-19 and to investigate whether the neuromuscular junction is the cause of fatigue. Methods: 37 patients who had COVID-19 at least 12 weeks ago and continued to complain of fatigue and 37 healthy individuals were included in the study. The Fatigue Severity Scale (FSS) and Fatigue Impact Scale (FIS) questionnaires were applied to people with fatigue. Single Fiber Electromyography (SFEMG) was applied to all individuals and the obtained data were compared between the two groups. Results: 70.3% of the patients with Post Viral Fatigue Syndrome (PVFS) had increased fatigue severity. 45.9% of the patients experienced mild fatigue, 35.1% of them experienced moderate fatigue, 13.5% experienced significant fatigue and 5.4% of them had severe fatigue according to FIS. The number of fibers with pathologically increased jitter and the mean jitter values of patients with PVFS were significantly higher than those of healthy individuals. 59.4% of patients with PVFS had moderate motor end plate dysfunction on SFEMG and 13.6% had apparent motor end plate dysfunction. Conclusion: Patients with PVFS caused by COVID-19 have neuromuscular junction dysfunction. It is unclear why these individuals are affected, but abnormal immune responses can lead to this dysfunction.

Thin dielectric Al2O3 and SrO films obtained by thermal evaporation in vacuum, as well as Si3N4 and SiO2 films obtained by RF magnetron sputtering, were studied by atomic force microscopy. The metric and fractal parameters of dielectric layers are estimated using the Gwyddion graphical program for analyzing data from scanning probe microscopy. It has been established that the maximum values of the fractal dimension are characteristic of aluminum oxide films with a thickness of 0.5 μm, while the smallest root-mean-square roughness is characteristic of strontium oxide films. The prospects for using the analyzed dielectric films as insulating layer of sensitive elements of strain gauge pressure sensors with a conductive elastic element are demonstrated.

It was shown that more strong correlation (rk = 0,78) with AMR-effect's value in film observe for surface resistivity that can use for AMR-effect rising.
Theoretical Features of the Application of Modified Coupling of Modes Model and its Formalization Based on P-Matrices for Calculating the Frequency Responses of SAW filters
Authors:   Saint Petersburg Electrotechnical University ", Koigerov A.S. ,   LETI",   , 197376, St. Petersburg, Russian Federation
Published: March 2024

Surface acoustic wave (SAW) filters are widely used in various applications, including wireless communication systems and radar systems, due to their advantages such as small size, low cost, high reliability and excellent performance in terms of insertion loss and out-of-band suppression. The most important stage in the development of SAW filters is mathematical modeling. Reducing the design time while reducing the cost of developing filters is an urgent task that can be solved both through the use of modern computing soft and by improving and developing already known modeling tools. The purpose: theoretical analysis and experimental verification of the possibility of implementing the proposed method for calculating SAW devices based on modified equations for coupling of modes (COM) model. Results: the current state of the analytical approach to calculating SAW filters based on the modified COM model and the formalization of this approach based on P-matrices are shown. The main responses of P-matrices are theoretically calculated and presented using the example of a resonator filter on leaky SAW at 64°YX-cut lithium niobate. The filter has a relative bandwidth of 5 %, insertion loss of —1.2 dB and rejection of —40 dB. The results of the calculated and experimental frequency responses of the filter are compared. The proposed analytical approach to designing SAW bandpass filters allows you to quickly and relatively accurately predict frequency responses at the modeling stage, thereby reducing the number of experimental iterations and increasing the efficiency of development.
Research Perspectives: An Encompassing Framework for Conceptualizing Space in Information Systems: Philosophical Perspectives, Themes, and Concepts
Authors: Haj-Bolouri Amir ,   University West, Conboy Kieran ,   University of Galway, Gregor Shirley ,   Australian National University
Published: March 2024

The conceptualization of space is integral to many of the diverse forms of information systems—for example, the physical space represented in geographical information systems and the virtual space of simulated worlds. Yet despite its importance and centrality, the conceptualization of space in information systems is not as sophisticated or mature as in other fields. A lack of attention to the diversity of perspectives on space hampers ongoing research and the re-visioning of phenomena that could lead to new insights in information systems. The aim of this paper is to develop an encompassing framework that provides a comprehensive view of philosophical perspectives, spatial themes, and concepts of space that are relevant to information systems. As a result of an extensive literature review, an encompassing framework is presented that includes four prominent spatial themes: representing space, differentiating space, disclosing space, and intuitive space. Each theme is related to its key characteristics and features and underlying philosophical perspectives. The paper demonstrates how the new framework can facilitate IS scholars’ expansive analysis in scholarly work and assist editors and reviewers in evaluating papers concerning space in IS and shows how the re-visioning of phenomena can lead to transformational shifts in understanding IS phenomena.

Sponsored search advertising has become an important venue for firms competing for consumers. As a result, many keywords attract a large number of bidders, and the competing advertisers may be quite heterogeneous. We examine whether this heterogeneity impacts how consumers perceive and react to such competitions. To this end, we draw on the theory of strategic groups to prescribe the structure of the competitive environment and investigate how strategic groups impact consumers’ clicking and website-visit behavior when viewing sponsored search results. Our unique datasets that combine search results from Google and consumers’ clickstream data enable us to disentangle such an impact. We find strong positive externality for within-group competitors relative to across-group competitors: (1) consumers are more likely to co-visit two firms that belong to the same strategic group, as opposed to two firms from different groups when both firms appear in the search results; (2) the presence of a firm in the search results primes consumers to visit other firms from the same strategic group even when the other firms do not appear in the search results. Our findings contribute to the sponsored search and strategic group literature by theorizing and empirically verifying consumers’ website-visit behaviors from the strategic group perspective.

Social media firestorms pose a significant challenge for firms in the digital age. Tackling firestorms is difficult because the judgments and responses from social media users are influenced by not only the nature of the transgressions but also by the reactions and opinions of other social media users. Drawing on the heuristic-systematic information processing model, we propose a research model to explain the effects of social impact (the heuristic mode) and argument quality and moral intensity (the systematic mode) on perceptions of firm wrongness (the judgment outcome) as well as the effects of perceptions of firm wrongness on vindictive complaining and patronage reduction. We adopted a mixed methods approach in our investigation, including a survey, an experiment, and a focus group study. Our findings show that the heuristic and systematic modes of information processing exert both direct and interaction effects on individuals’ judgment. Specifically, the heuristic mode of information processing dominates overall and also biases the systematic mode. Our study advances the literature by offering an alternative explanation for the emergence of social media firestorms and identifying a novel context in which the heuristic mode dominates in dual information processing. It also sheds light on the formulation of response strategies to mitigate the adverse impacts resulting from social media firestorms. We conclude our paper with limitations and future research directions.

The peculiarities of the geological and technical conditions of the coal deposits of the Donetsk coal basin, which are concentrated within the Donetsk and Luhansk regions, are revealed. The main indicators are given and an analysis of the technical and economic state of the coal industry is performed using the example of the main coal mining enterprises of the studied territories. An assessment of the complex impact on the surrounding natural environment сreated by the main coal-mining enterprises was carried out, based on a detailed examination and identification of a number of factors of the creation of man-made load within the limits of technology technical complexes of coal mining facilities. The assessment of technogenic and environmental risk based on the criteria of ecological and economic efficiency of coal mining enterprises of Donetsk and Luhansk regions made it possible to form the first approximate, but scientifically based ideas about the profitability (unprofitability) of coal mining activities of some enterprises, which is the basis for the further development of recommendations on consistency and expediency closing of mines in order to reduce the technogenic load. The article analyzes and uses data from the official environmental reporting of coal-mining enterprises, data from the Geoinform Ukrainy State Research Institute, the Ministry of Energy, the State Statistics Service, and scientific and methodological sources. According to the results of the assessment of the parameter of ecological and economic efficiency of enterprises and analysis of its influence on the formation of ecological safety of production, none of the main coal-mining enterprises of Donetsk and Luhansk regions is considered ecologically safe. Enterprises of SE "Lysychanskvugilya", SE "Pervomaiskvugilya" (Luhansk region), as well as enterprises of SE "Myrnogradvugilya" and SE "Selydivvugilya" (Donetsk region) are characterized by the lowest value of the coefficient of optimality of technological processes and are classified as extremely environmentally dangerous enterprises according to the results of the assessment.

On the basis of geological mapping, structural, mineralogical, petrographic, geochemical, petrophysical studies in the Pivdennyi and Pivnichnyi iron ore quarries of the Saksahansk district of the Kryvyi Rih iron ore basin (Kryvbas), a "new" morphological and genetic type of anthropogenic formations – collapse breccias formed as a result of rock masses displacement over underground mining zones – has been identified. These breccias make up huge volumes within the quarries, forming virtually new large-scale anthropogenic geological bodies with morphology, material composition and physical properties that differ from the original parent rocks. They occupy almost 100 % of the axial areas of the quarries, as well as significant volumes of their western ("hanging") sides. Together with the remnants of ferruginous quartzite and rich ore leftover from underground mining, they are the subject of modern industrial mining. Breccia collapses are new anthropogenic geological rocks. Genetically and morphologically, they fully correspond to the essence of anthropogenic formations and it is quite legitimate to apply the conceptual and legal framework of anthropogenic deposits to them in case of their economically feasible extraction, just as it is generally recognised for bulk dumps and sludge dumps. All this raises the question of the relevance of including these formations in the modern classifications of anthropogenic deposits of Kryvbas as a separate type.

The paper presents the data generalization of the observations of hydrogeological monitoring of mining sites on the dynamics of groundwater level. The processing of hydro-regime studies conducted in 2009-2021 in the area of the mine bypass of the № 2 pit was carried out. Hydrogeological sections reflecting changes in water levels over time were prepared. The most important factor in the lowering of the ground surface is salt karst development. The evaluation of the intensity of karst collapse processes was based on the interpretation of the results of the dynamics of the subsurface water level. The site network consists of more than 30 observation wells drilled into suprasaline and Quaternary aquifers. The main causes of deformation of the salt rock massif and the earth's surface have been identified. These are a decrease in the geomechanical strength of the rock due to its hydration and subsequent subsidence under the geostatic load of the overlying rock, and subsidence of the clay layer covering the salt rock due to the karst process. Based on the observed data, hydrogeologically oriented spatial zoning of the mining concession was performed. As a result of the development of a complex depression in the area of influence of the karst drainage, a drop in the water level in the gypsum-clay horizons was observed over the entire area in 2009-2019. The depression funnel runs in a northwesterly direction, indicating the development of a karst channel in the salts. Significant inflow of suprasaline water in the southwestern and central parts of the mine field combined with intense karstification of the salt massif and gypsum-clay cap deposits within the depression funnel resulted in significant deformation of the earth's surface, formation of karst funnels, and technogenic and ecological threats to critical infrastructure objects. To prevent a man-made ecological catastrophe, it is urgent to develop a scientific rationale for the maximum permissible changes in the environmental parameters of the man-made geological system of the № 2 mine of the Stebnytsky potash deposit during the post-mining phase.
