Green criminology has been advancing a focus on environmental crimes and harms. Extending this inquiry into avoidable and avertable environmental harms is a key function of both green criminology and zemiology. However, while the former seeks to expand regulatory frameworks, the latter contains within it the potential for a more holistic reimagining of the social world. Based on a methodology that combines qualitative methods (key informant interviews), a zemiological analysis, and the political ecology of Felix Guattari, we present a reconceptualization of harm inflicted by mineral extractivism in Peru's Cerro de Pasco. The analysis utilizes the concept of transversal harm, which allows us to move beyond the criminal and civil damage of corporate crime and negligence, and to capture the collective and continuous impact of mineral extractivism. A discussion of transversal harm as a potential new avenue for expanding the conceptual boundaries of studying environmental harm concludes the article. [ABSTRACT FROM AUTHOR]

The thermohydraulic performance of an enhanced PTC's tube is evaluated in this paper. A passive method is used by introducing transversal inserts on the bottom part of the receiver. The height of the inserts is investigated using MCRT method coupling FVM for Reynolds number range from 2.36 · 104 to 11.83 · 104. The heat transfer fluid used in this study is the Therminol®VP1. The numerical results show that the tube enhanced by inserts augments the reliability of the system, and the introduction of the inserts into the receiver tube decreases the temperature difference over the circumferential area of the absorber tube and minimizes the heat losses and also increase the lifetime of the receiver.

This paper investigates the intricate energy distribution patterns emerging at an orthotropic piezothermoelastic half-space interface by considering the influence of a higher-order three-phase lags heat conduction law, accompanied by memory-dependent derivatives (referred to as HPS) within the underlying thermoelastic half-space (referred to as TS). This study explores the amplitude and energy ratios of reflected and transmitted waves. These waves span various incident types, including longitudinal, thermal, and transversal, as they propagate through the TS and interact at the interface. Upon encountering the interface, an intriguing dynamic unfolds: three waves experience reflection within the TS medium, while four waves undergo transmission into the HPS medium. A graphical representation effectively illustrates the impact of higher-order time differential parameters and memory to offer comprehensive insights. This visual representation reveals the nuanced fluctuations of energy ratios with the incidence angle. The model astutely captures diverse scenarios, showcasing its ability to interpret complex interface dynamics. [ABSTRACT FROM AUTHOR]

Introduction: In the academic world, scientific publication has become a constant problem, both in its quantitative and qualitative elements. Objective: To characterize MEDISAN's publication rate according to some aspects of its scientific and editorial production. Methods: An observational, descriptive and transversal research, of bibliometric type, was carried out on the scientific production of MEDISAN journal from Santiago de Cuba during the five-year period 2017-2021. The study population was made up of all scientific articles published in that period according to the records of SciELO Citation Index and Google Scholar databases, as well as those of the journal itself on the Open Journal Systems. Results: During the analyzed period, 38 issues were published, which included 679 articles and 2,367 authors. The year 2017 stood out with the highest number of publications (31.8%) and the year 2019 with a lower number (14.3%). Cuban authors had the greatest contribution (629 articles), especially those from Santiago de Cuba province, where professionals from University of Medical Sciences stood out, with 50.1% of all production. The h5 index revealed a trend of increasing citations received by the journal, since in 2021 it was 23 and in 2022 it increased to 27. Conclusions: The analysis of scientific and editorial production revealed the strengths and weaknesses of the journal, which makes it possible to draw up policies to increase its quality and, with it, its visibility in databases.

The research results published so far have shown that success in mathematics positively affects the retention rate at technical and economic universities. Various studies have explored different forms, methods, and tools in mathematics teaching to improve student success, but an effective teaching model is yet to be identified. Based on previous experience and published results, a model of effective teaching was proposed with an emphasis on developing selected cross-sectional competencies to increase student retention. A recent study aimed to verify the effectiveness of this model in the pilot subject Mathematics I. The study included 211 first-year students of 7 bachelor's technical-economic study programs. Results showed significant improvement in the group of students who struggled with mathematics. The study confirmed that an appropriately chosen intervention in mathematics can increase the success rate of completing technical and economic study programs, and this approach can also be applied at other universities.

We obtain sharp L p - L q estimates for fractional integrals generated by Radon transforms of the following three types: The classical Radon transform over the set of all hyperplanes in ℝ n , the Strichartz transversal transform over only those hyperplanes which meet the last coordinate axis, and the Radon transform associated with paraboloids. The method relies on a version of Stein's interpolation theorem for analytic families of operators communicated by L. Grafakos. [ABSTRACT FROM AUTHOR]

The anti-gender movement has been publicly pursuing its quarrel against the social, academic, and political contexts of gender. Thus, it has also been constituting a basis of activism for fundamentalists, nationalists, and conservatives. In this article, we argue that recent instances show the movement has a reciprocal strategy, which articulates its structural, civil, and political aspects of counter-mobilization. After explaining the fundamentals of these aspects, we focus on the case of Turkey to embody our theoretical discussions. We also attempt to offer a transversal strategy for broad-based coalitions that can challenge the movement by categorizing its recent reflections. [ABSTRACT FROM AUTHOR]

In this paper, equivalent circuit models are first presented for characterizing CPW SSPPs with etched slot. The asymptotic frequency and dispersion are investigated based on the theoretical model. And the analyses reveal that both the asymptotic frequency and dispersion curve can be manipulated by changing the inductance brought by the etched slots and the capacitance of the loaded capacitors. To validate the propagation performance, the proposed SSPP structure was fabricated and tested. The experimental results are consistent with the theoretical analysis, indicating that the designed SSPP structure possesses excellent low-pass filtering characteristics. Compared with traditional SSPP structures, the proposed structure exhibits a much narrower transversal width and does not require mode-conversion structures. [ABSTRACT FROM AUTHOR]

This paper proposes a transversal dual-band wideband bandpass filter (BPF) with two transmission paths. We introduced two short coupled lines as the ideal 180° phase shift structure to realize the additional transmission path. A highly selective passband can be achieved by obtaining transmission zeros through a lateral signal cancellation mechanism. Using the classical odd/even mode analysis, seven modes can be excited for the dual-wideband structure. The fractional bandwidth of the first wide passband can reach 107% for multi-service applications. The presented transversal BPF with dual wideband is fabricated for verification. Good agreement between experimental results and simulation predictions validates the effectiveness of the proposed design methodology. [ABSTRACT FROM AUTHOR]

Adopting the omni-Lie algebroid approach to Dirac–Jacobi structures, we propose and investigate a notion of weak dual pairs in Dirac–Jacobi geometry. Their main motivating examples arise from the theory of multiplicative precontact structures on Lie groupoids. Among other properties of weak dual pairs, we prove two main results. (1) We show that the property of fitting in a weak dual pair defines an equivalence relation for Dirac–Jacobi manifolds. So, in particular, we get the existence of self-dual pairs and this immediately leads to an alternative proof of the normal form theorem around Dirac–Jacobi transversals. (2) We prove the characteristic leaf correspondence theorem for weak dual pairs paralleling and extending analogous results for symplectic and contact dual pairs. Moreover, the same ideas of this proof apply to get a presymplectic leaf correspondence for weak dual pairs in Dirac geometry (not yet present in literature). [ABSTRACT FROM AUTHOR]

When digital tools or spaces are involved in the design and implementation of qualitative research projects, the researcher is faced with the need to develop another type of competence, computational. Digital tools and spaces are growing avenues which facilitate data collection and analysis in new ways, such as through online surveys, videoconferencing platforms, social media sites, and qualitative data analysis software (QDAS). To utilize these tools, researchers need both computational competence and transversal skills. These skills allow the researcher (or research team) to transfer their knowledge of designing and implementing qualitative research to the digital realm, assuring trustworthiness and ethical behavior in using a digital tool or space. This essay discusses these two dimensions and how appropriating computational competence and transversal skills through digital tools or spaces may lead to higher-quality research projects.

We provide a systematic treatment of boundaries based on subgroups K ⊆ G for the Kitaev quantum double D(G) model in the bulk. The boundary sites are representations of a * -subalgebra Ξ ⊆ D(G) and we explicate its structure as a quasi-Hopf * -algebra dependent on a choice of transversal R. We provide decomposition formulae for irreducible representations of D(G) pulled back to Ξ. As an application of our treatment, we study patches with boundaries based on K = G horizontally and K = {e} vertically and show how these could be used in a quantum computer using the technique of lattice surgery. More abstractly, we also provide explicitly the monoidal equivalence of the category of Ξ-modules and the category of G-graded K-bimodules and use this to prove that different choices of R are related by Drinfeld cochain twists. Examples include Sn−1 ⊂ Sn and an example related to the octonions where Ξ is also a Hopf quasigroup. [ABSTRACT FROM AUTHOR]

This paper aims at investigating the failure response of expanded metal meshes subject to transversal impact. Firstly, the study is performed through explicit nonlinear finite element analysis, in which a numerical model is developed to determine the impact performance and failure mode of expanded metal meshes. Thereafter, the effect of expanded metal cell geometries, impact mass and velocity on the structural response of the meshes is analyzed. Then the perforation resistance of the impacted meshes is assessed and analyzed by means of vulnerability curves for various expanded metal geometries subject to transversal impact. The extent of damage in the meshes is also evaluated, and the maximum displacements achieved in each impact scenario is quantified. At the end, it is demonstrated that the perforation performance of the meshes depends on the expanded metal cell dimensions expressed as a combination of the strand cross-section and major axis length. Finally, the results also show the feasibility of using expanded metal meshes to protect structures impacted by flying debris. [ABSTRACT FROM AUTHOR]

The objective if this study was to determine the relation that exists between the predominant tendency of the learning style, according to the Felder-Silverman model, and partial and final academic performance of the students attending the subject Morphology and Function I. A transversal study was carried out among 231 college students who joined the Faculties of Health and Education during the first term of 2019. They received the Index of Learning Styles Questionnaire and it was correlated with the mark of the theoretical test n°1, the practical evaluation n° 1 and the final average of the course. Results showed that 53.4 % of the total numbers of students assessed are visual, for these pupils the Spearman correlation coefficient was -0.378 for the theoretical test (p<0.001), -0.467 for the practical evaluation (p<0.001) and -0.500 for the final average (p<0.001). Visual students have higher average marks in the theoretical test and the final average contrasted with the active ones (p<0.05). We concluded that the predominant tendency is the visual style. For these students there is an inverted and statistically significant correlation with the academic performance. Besides, they show significantly higher average marks than the other tendencies.

In this paper, a contextualization of the teaching-learning process of the English language for specific purposes in the Civil Engineering career is presented. Said contextualization is based on an epistemological and praxiological perspective that recognizes the holistic, complex, interdisciplinary and integrating nature of the language contents, as well as the other disciplines within the degree. The fundamental purpose is to improve the training of the civil engineer, managing to establish a connection between the teaching-learning process of English and the professional profile through a transversal approach that covers the different subjects of the career. Consequently, the distinctive peculiarity of the process of obtaining information and communication in the field of civil engineering would be highlighted, playing a crucial dynamic role. To address this study, a systematic review methodology was used in high-impact databases, allowing a comprehensive analysis of English language teaching in various areas of study. As a result of this research, didactic strategies were proposed in order to strengthen the teaching-learning process in technical fields such as Civil Engineering. [ABSTRACT FROM AUTHOR]

The Lovász local lemma (LLL) is a keystone principle in probability theory, guaranteeing the existence of configurations which avoid a collection ℬ$$ \mathcal{B} $$ of "bad" events which are mostly independent and have low probability. A seminal algorithm of Moser and Tardos (J. ACM, 2010, 57, 11) (which we call the MT algorithm) gives nearly‐automatic randomized algorithms for most constructions based on the LLL. However, deterministic algorithms have lagged behind. We address three specific shortcomings of the prior deterministic algorithms. First, our algorithm applies to the LLL criterion of Shearer (Combinatorica, 1985, 5, 241–245); this is more powerful than alternate LLL criteria and also leads to cleaner and more legible bounds. Second, we provide parallel algorithms with much greater flexibility. Third, we provide a derandomized version of the MT‐distribution, that is, the distribution of the variables at the termination of the MT algorithm. We show applications to non‐repetitive vertex coloring, independent transversals, strong coloring, and other problems. [ABSTRACT FROM AUTHOR]

In this study, a transversal ultrasonic vibration-assisted riveting (TUVAR) process was developed to improve the uniformity of CFRP riveted lap joint interference-fit size, which provided a possibility for the quantization of riveted joint interference-fit sizes. The relationship between the process parameters of vibration amplitude, vibration duration, and roughness with interference-fit sizes by algorithms, through the minimum coefficient variance of interference-fit size (ICV-min) to confirm the riveting process parameters of the quantized average interference-fit sizes (IA). The experimental verification results showed that the mean absolute percentage error of measured IA and predicted IA is less than 10%. Furthermore, the tensile tests were carried out to investigate the effect of interference-fit size {1.4%, 1.6%, 1.8%, and 2.0%} on mechanical performances of CFRP riveted lap joints by TUVAR, and the tensile strength presents first-up then down with the interference-fit size increase, the maximum ultimate tensile strength is the riveted lap joint with the interference-fit size of 2.0%. Hence, the quantitative optimization method can well predict the riveting process parameters corresponding to the most uniform interference-fit size. [ABSTRACT FROM AUTHOR]

Objective : Passive alveolar molding (PAM) and nasoalveolar molding (NAM) are established presurgical infant orthodontic (PSIO) therapies for cleft lip palate (CLP) patients. PAM guides maxillary growth with a modified Hotz appliance, while NAM also uses extraoral taping and includes nasal stents. The effects of these techniques on alveolar arch growth have rarely been compared. Material and methods: We retrospectively compared 3D-scanned maxillary models obtained before and after PSIO from infants with unilateral, non-syndromic CLP treated with PAM (n = 16) versus NAM (n = 13). Nine anatomical points were set digitally by four raters and transversal/sagittal distances and rotations of the maxilla were measured. Results: Both appliances reduced the anterior cleft, but NAM percentage wise more. NAM decreased the anterior and medial transversal width compared to PAM, which led to no change. With both appliances, the posterior width increased. The alveolar arch length of the great and small segments and the sagittal length of the maxilla increased with PAM but only partially with NAM. However, NAM induced a significant greater medial rotation of the larger and smaller segment compared to PAM with respect to the lateral angle. Conclusions: NAM and PAM presented some significant differences regarding maxillary growth. While NAM reduced the anterior cleft and effectively rotated the segments medially, PAM allowed more transversal and sagittal growth. Clinical relevance: The results of this study should be taken into consideration when to decide whether to use PAM or NAM, since they show a different outcome within the first few months. Further studies are necessary regarding long-term differences. [ABSTRACT FROM AUTHOR]

The forms in which Environmental Education (EE) is included in the curriculum are a long-standing concern in the Latin American didactic field. In this paper we analyse the current curricular designs for the Basic Secondary School in the province of Buenos Aires, Argentina. Although in hierarchically superior regulations (Provincial Education Law and General Framework of Curricular Policy), EE is based on critical and ethnographic perspectives, it has an uneven transversal presence in the curricular designs. Some subjects present an empty EE curriculum, while others show fragmentary and contradictory perspectives. Only in Social Sciences, Geography and Citizenship Building is there a critical and ethnographic vision, linked to contemporary environmental conflicts. From Geography we recovered the experiential dimension and the enjoyment of the environment as a contribution to the pedagogies of environmental conflict and to the ongoing implementation the new national EE regulations.

RF photonic transversal signal processors, which combine reconfigurable electrical digital signal processing and high-bandwidth photonic processing, provide a powerful solution for achieving adaptive high-speed information processing. Recent progress in optical microcomb technology provides compelling multi-wavelength sources with a compact footprint, yielding a variety of microcomb-based RF photonic transversal signal processors with either discrete or integrated components. Although they operate based on the same principle, the processors in these two forms exhibit distinct performances. This paper presents a comparative investigation of their performances. First, we compare the performances of state-of-the-art processors, focusing on the processing accuracy. Next, we analyze various factors that contribute to the performance differences, including the tap number and imperfect response of experimental components. Finally, we discuss the potential for future improvement. These results provide a comprehensive comparison of microcomb-based RF photonic transversal signal processors implemented using discrete and integrated components and provide insights for their future development.

Methods of increasing the bearing capacity of corrugated metal structures of transport constructions using transversal stiffening ribs in the form of additional corrugation and stiffeners are given. Based on the theory of elasticity, a mathematical model for estimating the stress-strain state of transport constructions made of corrugated metal structures reinforced with stiffening ribs in the form of double corrugation was developed. The method of determining equivalent forces during rolling stock passage is offered. It has been established that double corrugation increases the bearing capacity of corrugated metal structures. Therefore, additional corrugation of corrugated metal structures reduces stresses by up to 20% and deflections by 50%. The obtained results show that the increase in rolling stock speed does not lead to a significant increase in stresses and strains in CMS when the railway track corresponds to the design state.

Reconfigurable plasmonic-photonic electromagnetic devices have been incessantly investigated for their great ability to optically modulate through external stimuli to meet today's emerging needs, with chalcogenide phase-change materials being promising candidates due to their remarkably unique electrical and optics, enabling new perspectives in recent photonic applications. In this work, we propose a reconfigurable resonator using planar layers of stacked ultrathin films based on Metal-dielectric-PCM, which we designed and analyzed numerically by the Finite Element Method (FEM). The structure is based on thin films of Gold (Au), aluminum oxide (Al2O3), and PCM (In3SbTe2) used as substrate. The modulation between the PCM phases (amorphous and crystalline) allows the alternation from the filter to the absorber structure in the infrared (IR) spectrum (1000–2500 nm), with an efficiency greater than 70% in both cases. The influence of the thickness of the material is also analyzed to verify tolerances for manufacturing errors and dynamically control the efficiency of transmittance and absorptance peaks. The physical mechanisms of field coupling and transmitted/absorbed power density are investigated. We also analyzed the effects on polarization angles for Transversal Electric (TE) and Transversal Magnetic (TM) polarized waves for both cases. [ABSTRACT FROM AUTHOR]

The article exposes the results achieved in an investigative study aimed at substantiating the proposal of an educommunicative model aimed at promoting citizen participation in the exercise of the right to communication in Loja-Ecuador. It is based on the communication model for social change and Educommunication as a new transdisciplinary paradigm that contemplates knowledge as a procedural, transdisciplinary, interdiscursive and transversal whole within the framework of communicative management for the construction of open and dialogical communicative ecosystems. The regularities found in the diagnosis of the context, created the bases for the construction of the educommunicative model that will act in favor of citizen empowerment in the exercise of their rights to communication.

Using a dual-task paradigm, the present investigation examined whether processes related to line orientation play a critical role in the production of the Poggendorff illusion. In Experiment 1, we assessed the magnitude of the Poggendorff illusion under three different task conditions. In the single-task condition, participants were asked to report how they perceive the alignment of transversal lines in the Poggendorff figure. In two different dual-task conditions, the participants were asked to read aloud the time displayed on a digital or analogue clock while also performing the Poggendorff perception task. The method of constant stimuli was used to calculate the point of subjective equality (PSE) and bistability width values, which represent illusion strength and perceptual uncertainty, respectively. PSEs indicated that the magnitude of the illusion did not vary between single, dual-analogue, and dual-digital task conditions, which suggests that the additional demands placed by the dual tasks had no effect on the illusion strength. Perceptual uncertainty and clock-reading errors were greater in the dual-analogue task condition. Experiment 2 revealed that the analogue clockface was more difficult to read than the digital clockface. Based on these results, we conclude that having participants perform a secondary task does not influence the magnitude of the Poggendorff illusion. [ABSTRACT FROM AUTHOR]

The clique transversal problem and its variants have garnered significant attention in the last two decades due to their practical applications in communication networks, social-network theory and transceiver placement for cellular telephones. While previous research primarily focused on determining the polynomial-time solvability or NP-hardness/NP-completeness of specific graphs, this paper adopts a parameterized-complexity approach. It thoroughly explores four clique transversal variants: the d-fold transversal problem, the { d } -clique transversal problem, the signed clique transversal problem and the minus clique transversal problem. The paper presents various findings regarding the parameterized complexity of the clique transversal problem and its variants. It establishes the W[2]-completeness and para-NP-completeness of the d-fold transversal problem, the { d } -clique transversal problem, the signed clique transversal problem and the minus clique transversal problem within specific graph classes. Additionally, it introduces fixed-parameter tractable algorithms for planar graphs and graphs with bounded treewidth, offering efficient solutions for these specific instances of the problems. The research further explores the relationship between planar graphs and graphs with bounded treewidth to enhance the time complexity of the d-fold clique transversal problem and the { d } -clique transversal problem. By analyzing the parameterized complexity of the clique transversal problem and its variants, this research contributes to our understanding of the computational limitations and potentially efficient algorithms for solving these problems.

A crack is found with the BG27CrMoV trenchless geological drill pipe. Briefly analyzed are the main aspects of the said failure drill pipe, including the operation conditions, the chemical composition, the metallographic structure, the mechanical properties, and the composition of the corrosion products, etc. It is regarded via the analysis that the crack has nothing to do with the chemical composition, the metallographic structure and the mechanical properties of the failure drill pipe which are all normal. The analysis of the operation conditions and the corrosion products of the drill pipe reveals the existence of FeS in the later, which leads to such a conclusion that the crack of the failure drill pipe is caused by the SCC effect.

Introduction: Medical education should promote the development of skills and abilities that can be applied to real-world work performance. The aim of this study is to evaluate technical and methodological knowledge, as well as physicianpatient communication skills, as one of the most important transversal competencies that a good physician should acquire; all this in a reliable, accurate and objective way. Methods: We present a rubric specifically designed and implemented for the evaluation of specific and transversal competencies in the physiology practical sessions, during the second year of the medical degree. The assessment consists in two evaluation tests: 1) a theoretical test that consists of multiple-choice questions. Students must demonstrate that they have acquired adequate theoretical knowledge (specific competency "to know"); 2) a practical test, in which students are evaluated by the rubric through the simulation of a medical consultation. Thus, demonstrating their ability to execute/apply what they have learned in class (specific competency "to know how to do"). They are also evaluated on the transversal competencies that we call "communication with the patient" (transversal competency "to know how to be there") and "dealing with the patient" (transversal competency "to know how to be"). Results: We evaluated whether there were differences in the grades obtained by students when the transversal competencies were not assessed (academic years 2017-2018 and 2018-2019; n = 289), and when the transversal competencies were assessed by applying the rubric in the academic years 2019-2020, 2021-2022, and 2022-2023 (n = 526). Furthermore, we present a student perception that supports the use of clinical simulation and our rubric as a good method within the competency learning process. Discussion: The acquisition of these competencies, starting from the first courses of undergraduate education, helps to raise the students' awareness in the development of a more humanized medicine, allowing a better response to the patients' needs. Our rubric, which clearly indicate the performance criteria, have become an excellent method to carry out the assessment of competencies, both for students and teachers, since they allow to obtain clear evidence of the level of acquisition and application of knowledge.

The (a , b) - monochromatic transversal game is a combinatorial Maker-Breaker game where two players, Alice and Bob, alternately take turns colouring a and b vertices of a hypergraph in red and blue, respectively (either player may start the game). Alice tries to construct a hyperedge transversal, and Bob tries to prevent this. Alice wins if she obtains a red hyperedge transversal, and Bob wins if he obtains a monochromatic blue hyperedge. We study the game played on biclique-hypergraphs of powers of paths and powers of cycles, showing strategies that, depending on the choice of parameters a and b , allow a specific player to win the game.

The following reflection is framed in the context of the project "UNESCO Chair for Latin America, which was carried out at the Pilot University of Colombia from 2020 to 2022. For this opportunity, and thinking of contributing to the reflection on issues of territorial defense, and especially those that have to do with water defense, should be carried out together with the communities. At the beginning, the context of the problem is presented, whose transversal axis will be water as a potential resource of vitality, to later signify the presence and responsibility of the communities regarding its use, care, defense and appropriation, from a perspective of collective political conscience. This exercise of approaching a complex problem is supported by a contextual and localized analysis of the last decade, in which community struggles and territorial claims become visible, in the midst of the installation of a model that makes land goods such as water precarious and usufructual, as well as stigmatizes and persecutes any expression that assumes its defense.

Basic income is the subject of an intense debate, which has been particularly relevant in relation to the concepts of 'distribution' and 'justice'. This is an idea that has developed into a transversal theory. Its scope is evidenced by the fact that it attracts not only leftwing political movements that understand the proposal to defend the extension of real freedom, but also liberals who advocate freedom for all, as opposed to dependence on the state. Objective: The purpose of this paper is to analyze and summarize various positions involved in this debate, which explores the relationship between justice and basic income. Methodology: The viewpoints of authors such as Van Parijs, Rawls, Dworkin, Nozick, Felipe Giménez Pérez, Daniel Raventós, Amartya Sen and Nancy Fraser were discussed and analyzed. The variety of authors and their analyses enabled for a diversified sample of positions. Results: Considering the limits and scope of some of the theoretical approaches focusing on the relationship between justice and basic income, the results of this research allow for a deeper understanding of the sociopolitical challenge of economic inequality through the idea of basic income, both on a nationstate scale and on a global scale. Conclusions: Basic income is presented to us as an instrument in the struggle for social justice in increasingly unequal societies, despite the wealth they generate. In this way, this manuscript aims to understand and present the various positions on the problem of justice and distribution that may arise when discussing basic income. The purpose is therefore to initiate a debate on basic income and integrate it into a common project for creating an inclusive society that is more egalitarian and fair for all.

This article seeks to outline schematically the philosophical problem that underlies the main thesis of the German philosopher Markus Gabriel, namely, that the world does not exist, or in other words, a totality of the real is neither possible nor conceivable, nor is there a transversal or fundamental element of reality as a whole This problem stems from the quintessential ontological question: What exists? This, in turn, is based on the question of what it means to exist. The analysis of the notion of existence will show that: (1) it cannot be an authentic property, as it does not allow the identification and distinction of objects; (2) because of this, there cannot be a total definition of 'existence,' and therefore, there cannot be a realm of objects characterized solely by it. The impossibility of this total realm will show that neither a totality of the real exists nor is conceivable. [ABSTRACT FROM AUTHOR]

We consider an integral transform which maps functions on the Euclidean half-space to integrals of these functions over hemispheres centered on the boundary hyperplane. The main results include sharp L p - L q estimates for this transform and new explicit inversion formulas under minimal assumptions for functions. The main idea is an intriguing connection between the hemispherical transform, the Radon transform over paraboloids, and the transversal Radon transform over hyperplanes meeting the last coordinate axis.

We prove that if H is a subgroup of a finite solvable group G such that the number of isotopic classes of right transversals of H in G is 1, then H is normal in G. [ABSTRACT FROM AUTHOR]
