Special Objects: Social, Fictional, Modal, and Non-Existent.Maria J. García-Encinas &Fernando Martínez-Manrique (eds.) -2025 - Springer.detailsThis book proposes a different perspective on actual queries within the field of ontology. Focusing on non-standard objects, it offers original answers to classic problems in metaphysics, such as individuation, reference, existence and non-existence. The chosen ontological fields are, for this purpose, ontologies that essentially involve human social practices such as intentional objects, fictions, mental illnesses or social entities. Even though the papers can be read independently, readers will discover a number of original intersections that provide fresh points of entry (...) to contemporary metaphysical issues. By dealing with entities that are not so frequently addressed in related works, the book also contributes to broaden their perspective on ontology. Both scholars and students will find it particularly useful to have a survey about non-standard abstract entities that can provide new topics for their research. (shrink)

Teachers and Teaching: Subjectivity, performativity and the body.M. J. Vick &CarissaMartinez -2011 -Educational Philosophy and Theory 43 (2):178-192.detailsIt has become almost commonplace to recognise that teaching is an embodied practice. Most analyses of teaching as embodied practice focus on the embodied nature of the teacher as subject. Here, we use Butler's concept of performativity to analyse the reiterated acts that are intelligible as—performatively constitute—teaching, rather of the teacher as subject. We suggest that this simultaneously helps explain the persistence of teaching as a narrow repertoire of actions recognisable as ‘teaching’, and the policing of conformity to teaching thus (...) embodied. However, like performatively accomplished subjectivity, this repertoire is unstable and ambiguous, and thus open to change and disruption. Moreover, teacher subjectivities may lead them to mobilise these possibilities of disruption. (shrink)
Embedded feature selection for neural networks via learnable drop layer.M. J. JimÉnez-Navarro,M. MartÍnez-Ballesteros,I. S. Brito,F. MartÍnez-Álvarez &G. Asencio-CortÉs -forthcoming -Logic Journal of the IGPL.detailsFeature selection is a widely studied technique whose goal is to reduce the dimensionality of the problem by removing irrelevant features. It has multiple benefits, such as improved efficacy, efficiency and interpretability of almost any type of machine learning model. Feature selection techniques may be divided into three main categories, depending on the process used to remove the features known as Filter, Wrapper and Embedded. Embedded methods are usually the preferred feature selection method that efficiently obtains a selection of the (...) most relevant features of the model. However, not all models support an embedded feature selection that forces the use of a different method, reducing the efficiency and reliability of the selection. Neural networks are an example of a model that does not support embedded feature selection. As neural networks have shown to provide remarkable results in multiple scenarios such as classification and regression, sometimes in an ensemble with a model that includes an embedded feature selection, we attempt to embed a feature selection process with a general-purpose methodology. In this work, we propose a novel general-purpose layer for neural networks that removes the influence of irrelevant features. The Feature-Aware Drop Layer is included at the top of the neural network and trained during the backpropagation process without any additional parameters. Our methodology is tested with 17 datasets for classification and regression tasks, including data from different fields such as Health, Economic and Environment, among others. The results show remarkable improvements compared to three different feature selection approaches, with reliable, efficient and effective results. (shrink)
From simple to complex: a sequential method for enhancing time series forecasting with deep learning.M. J. Jiménez-Navarro,M. Martínez-Ballesteros,F. Martínez-Álvarez,A. Troncoso &G. Asencio-Cortés -2024 -Logic Journal of the IGPL 32 (6):986-1003.detailsTime series forecasting is a well-known deep learning application field in which previous data are used to predict the future behavior of the series. Recently, several deep learning approaches have been proposed in which several nonlinear functions are applied to the input to obtain the output. In this paper, we introduce a novel method to improve the performance of deep learning models in time series forecasting. This method divides the model into hierarchies or levels from simpler to more complex ones. (...) Simpler levels handle smoothed versions of the input, whereas the most complex level processes the original time series. This method follows the human learning process where general/simpler tasks are performed first, and afterward, more precise/harder ones are accomplished. Our proposed methodology has been applied to the LSTM architecture, showing remarkable performance in various time series. In addition, a comparison is reported including a standard LSTM and novel methods such as DeepAR, Temporal Fusion Transformer, NBEATS and Echo State Network. (shrink)
Understanding Pay Satisfaction: Effects of Supervisor Ethical Leadership on Job Motivating Potential Influence.Pablo Ruiz-Palomino,Francisco J. Sáez-Martínez &Ricardo Martínez-Cañas -2013 -Journal of Business Ethics 118 (1):31-43.detailsTraditionally, research focused on determining the causes of employee pay satisfaction has investigated the influence of job-related inputs, both extrinsic and intrinsic to the job itself. Together with these inputs, pay-related fairness issues have played an important role in explaining the phenomenon. However, few studies consider the factors linked to fairness issues, such as ethical leadership. Because ethical leadership necessarily entails the concept of fairness, it seemingly should have a positive effect. Furthermore, because the presence of supervisor ethical leadership (SEL) (...) offers strong chances for employees to achieve moral accomplishments and excel in the practice of their jobs, SEL should enhance the effects of intrinsic job inputs. Whereas high job motivating potential (JMP) makes it easier for employees be self-actualized, moral fulfillment is necessary for them to obtain authentic self-actualization at work and minimize the impact of pay deficiencies. Along with SEL, JMP should be shaped to increase positive experiences of job meaningfulness, responsibility for job outcomes, and knowledge of results at work, which can lead to enjoyment in doing the job in itself, not just for compensation-related motives. Hierarchical regression analysis with a sample of 151 employees in a diverse set of Spanish organizations supports the direct effects of JMP and SEL and shows that higher levels of SEL increase the positive effects of JMP on pay satisfaction. The practical implications of these findings and further research directions conclude this article. (shrink)
Coronavirus Awareness and Mental Health: Clinical Symptoms and Attitudes Toward Seeking Professional Psychological Help.Miguel Landa-Blanco,Ana Landa-Blanco,Claudio J. Mejía-Suazo &Carlos A. Martínez-Martínez -2021 -Frontiers in Psychology 12.detailsThe current study analyzed the relationship between Coronavirus Awareness, mental health, and willingness to seek professional psychological help. This was made through a quantitative approach, using online questionnaires to collect data from 855 subjects. The questionnaires included the Brief Symptom Inventory to measure mental health indicators, the Attitudes Toward Seeking Professional Psychological Help Scale–Short Form, and the Coronavirus Awareness Scale-10. An Exploratory Factor Analysis suggests that three factors underlie the CAS-10: Coronavirus Concern, Exaggerated Perception, and Immunity Perception. Results indicate a (...) significant positive correlation between Coronavirus Concern and both general anxiety and phobic anxiety symptoms. Immunity Perception is positively related to paranoid ideation and psychotic symptoms. A Mediation Analysis determined that Coronavirus Concern has a significant positive direct effect on Openness to Seeking Psychological Treatment, while Exaggerated Perception and Immunity Perception scores have significant direct negative effects on the Value and Need in Seeking Treatment scores. Indirectly, the relationship between Coronavirus Concern and OPST is significantly mediated by anxiety symptoms. Similar results were found for the VNST subscale. There is a negative significant effect of Immunity Perception over OSPT mediated by Paranoid Ideation. However, the overall model only achieved small r2 coefficients for the OSPT and VNST scores. Comparisons in Coronavirus Awareness between sex, age, and the presence of children and older adults at home were also made. These results are discussed regarding their practical implications for mental health providers and policymakers. (shrink)
Roger Boscovich.J. Félix Fuertes Martínez &José López García -1992 -Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 7 (1-3):687-701.detailsRoger Boscovich, belonging to XVIII century, halfway from Newton to Faraday, is traditionally considered as a newtonian philosopher. Nevertheless, following Berkson’s suggestion, he could be a Field Theory forerunner. In this work, we will try to go on with the idea of this suggestion in order to show this possible Boscovich’s contribution.
Towards a homotopy domain theory.Daniel O. Martínez-Rivillas &Ruy J. G. B. de Queiroz -2022 -Archive for Mathematical Logic 62 (3):559-579.detailsAn appropriate framework is put forward for the construction of $$\lambda $$ -models with $$\infty $$ -groupoid structure, which we call homotopic $$\lambda $$ -models, through the use of an $$\infty $$ -category with cartesian closure and enough points. With this, we establish the start of a project of generalization of Domain Theory and $$\lambda $$ -calculus, in the sense that the concept of proof (path) of equality of $$\lambda $$ -terms is raised to higher proof (homotopy).

The Theory of an Arbitrary Higher \(\lambda\)-Model.DanielMartinez &Ruy J. G. B. de Queiroz -2023 -Bulletin of the Section of Logic 52 (1):39-58.detailsOne takes advantage of some basic properties of every homotopic \(\lambda\)-model (e.g. extensional Kan complex) to explore the higher \(\beta\eta\)-conversions, which would correspond to proofs of equality between terms of a theory of equality of any extensional Kan complex. Besides, Identity types based on computational paths are adapted to a type-free theory with higher \(\lambda\)-terms, whose equality rules would be contained in the theory of any \(\lambda\)-homotopic model.
Who Discovered the Binary System and Arithmetic? Did Leibniz Plagiarize Caramuel?J. Ares,J. Lara,D. Lizcano &M. A. Martínez -2018 -Science and Engineering Ethics 24 (1):173-188.detailsGottfried Wilhelm Leibniz is the self-proclaimed inventor of the binary system and is considered as such by most historians of mathematics and/or mathematicians. Really though, we owe the groundwork of today’s computing not to Leibniz but to the Englishman Thomas Harriot and the Spaniard Juan Caramuel de Lobkowitz, whom Leibniz plagiarized. This plagiarism has been identified on the basis of several facts: Caramuel’s work on the binary system is earlier than Leibniz’s, Leibniz was acquainted—both directly and indirectly—with Caramuel’s work and (...) Leibniz had a natural tendency to plagiarize scientific works. (shrink)
Formation Tracking of Heterogeneous Mobile Agents Using Distance and Area Constraints.E. G. Hernandez-Martinez,E. D. Ferreira-Vazquez,G. Fernandez-Anaya &J. J. Flores-Godoy -2017 -Complexity:1-13.detailsThis paper presents two formation tracking control strategies for a combined set of single and double integrator agents with an arbitrary undirected communication topology. The first approach is based on the design of distance-based potential functions with interagent collision avoidance using local information about the distance and orientation between agents and the desired trajectory. The second approach adds signed area constraints to the desired formation specification and a control strategy that uses distance as well as area terms is designed to (...) achieve tracking convergence. Numerical simulations show the performance from both control laws. (shrink)

The Ethical Challenges of the UN’s Clean Development Mechanism.Candace A.Martinez &J. D. Bowen -2013 -Journal of Business Ethics 117 (4):807-821.detailsThis paper examines the ethical implications of the Clean Development Mechanism, the United Nation’s climate change initiative that provides incentives to countries and firms in developed countries to motivate investments in greenhouse gas reduction projects in developing countries. Using the tenets of agency theory, we present a solid waste management project in El Salvador as an illustrative example of how the CDM can produce a disproportionately high social cost for the most marginalized populations in the developing world. We suggest that (...) the UN needs to reformulate the CDM so that it more effectively aligns the divergent goals of multiple actors and upholds the UN’s principles for sustainable development, including ethical firm-level behavior. By providing incentives for environmental, economic, and social value creation, the CDM would not only promote ethical norms for profit-seeking firms that participate in the program but also reinforce the UN’s twin pro-poor and environmental objectives.

Identifying the Correlations Between the Semantics and the Phonology of American Sign Language and British Sign Language: A Vector Space Approach.AuroraMartinez del Rio,Casey Ferrara,Sanghee J. Kim,Emre Hakgüder &Diane Brentari -2022 -Frontiers in Psychology 13.detailsOver the history of research on sign languages, much scholarship has highlighted the pervasive presence of signs whose forms relate to their meaning in a non-arbitrary way. The presence of these forms suggests that sign language vocabularies are shaped, at least in part, by a pressure toward maintaining a link between form and meaning in wordforms. We use a vector space approach to test the ways this pressure might shape sign language vocabularies, examining how non-arbitrary forms are distributed within the (...) lexicons of two unrelated sign languages. Vector space models situate the representations of words in a multi-dimensional space where the distance between words indexes their relatedness in meaning. Using phonological information from the vocabularies of American Sign Language and British Sign Language, we tested whether increased similarity between the semantic representations of signs corresponds to increased phonological similarity. The results of the computational analysis showed a significant positive relationship between phonological form and semantic meaning for both sign languages, which was strongest when the sign language lexicons were organized into clusters of semantically related signs. The analysis also revealed variation in the strength of patterns across the form-meaning relationships seen between phonological parameters within each sign language, as well as between the two languages. This shows that while the connection between form and meaning is not entirely language specific, there are cross-linguistic differences in how these mappings are realized for signs in each language, suggesting that arbitrariness as well as cognitive or cultural influences may play a role in how these patterns are realized. The results of this analysis not only contribute to our understanding of the distribution of non-arbitrariness in sign language lexicons, but also demonstrate a new way that computational modeling can be harnessed in lexicon-wide investigations of sign languages.
