There is much effort nowadays to protect communication networks against different cybersecurity attacks (which are more and more sophisticated) that look for systems’ vulnerabilities they could exploit for malicious purposes. Network Intrusion Detection Systems (NIDSs) are popular tools to detect and classify such attacks, most of them based on ML models. However, ML-based NIDSs cannot be trained by feeding them with network traffic data as it is. Thus, a Feature Engineering (FE) process plays a crucial role transforming network traffic raw (...) data onto derived one suitable for ML models. In this work, we study the effects of applying one such FE technique in different ways on the performance of two ML models (linear and non-linear) and their selected features. This the Feature as a Counter approach. The derived observations are computed from either with the same number of raw samples, (batch-based approaches) or by aggregating them by time intervals (timestamp-based approach). Results show that there is no significant differences between the proposed approaches neither in the performance of the models nor in the selected features that validate our proposal making it feasible to be widely used as a standard FE method.

We present the foucaultian critique of the transcendental theme. We will try to show, sharpening the layout of the problem, that the specific target of such critique is not so much the transcendental instance as such, present in a sui generis way in Foucault himself, as rather a certain interpretation of this instance, mastered by the “knowledge” scheme and its postulates of natural affinity, constituent subjectivity and transcendental theology. So we will determine, in the first place, the framework and reach (...) of such critique. Secondly, we will set forth the interpretation of the transcendental which rules in the foucaultian critique of this theme. In the third place, we will take into account the assumptions which rule in this interpretation. Finally, we will sketch the foucaultian idea of “knowledge” (savoir). (shrink)

El presente artículo da cuenta de las actitudes hacia los inmigrantes entre los estudiantes de educación secundaria de edades comprendidas entre 12 y 13 años en Extremadura, España. Los datos proceden de una investigación financiada por el Gobierno Regional de Extremadura y en ellos se muestran ¿mediante análisis de contenido y utilización de citas textuales¿ los componentes estructurales que alimentan las actitudes positivas y/o negativas hacia la inmigración y los inmigrantes por parte de los adolescentes extremeños, en la medida en (...) que son plenamente representativos en cuanto a actitudes y valores del conjunto nacional. El análisis nos permite establecer un modelo actitudinal frente a la inmigración que deberá ser probado en futuras investigaciones. (shrink)

O presente artigo parte do princípio de que há uma relação intrínseca entre a metafísica e a teodkeia. A primeira é um sistema que oferece sentido, inteligibilidade, verdade e universalidade. O seu pressuposto fundamental é o de Parménides e o de Hegel, ou seja, a correspondência entre ser e pensamento, a racionalidade do real e a realidade do racional. Este é o ponto de partida da teologia natural grega, do teísmo cosmológico cristão, do teísmo antropológico moderno e das filosofias do (...) progresso dos últimos séculos. A teodiceia procura superar o último obstáculo que se opõe a esses sistemas, o mal na sua tripla dimensão de mal metafísico, físico e moral. O mal é impermeável à razão e sem sentido, ou seja, é aquilo que mais impede a transparência e a inteligibilidade do mundo. Começando por assumir esta proposta, o autor analisa finalmente a crise actual do sujeito e da metafísica, a crise pós-mo-derna da razão e dos sistemas universais. O novo contexto em que nos encontramos, o de uma metafísica débil, oferece novas oportunidades à proposta cristã, à impossibilidade da teodiceia como teoria especulativa e à possibilidade de uma resposta de sentido e comprometida com aquilo que é o maior dos sem-sentidos, o mal. /// There is an intrinsk relation between metaphysics and theodicy. The first one is a system which offers meaning, intelligibility, truth and universality. Its fundamental presupposition is the Parmenidian one and the Hegelian one, the correspondence between being and thought, the rationality of what is real and the reality of what is rational. This is the starting point of the Greek natural theology, of the Christian cosmologkal theism, of the modern anthropological theism and of the philosophies of progress of the last centuries. Theodicy tries to overcome the last obstacle whkh opposes to those systems, evil in its triple dimension of metaphysical, physical and moral evil. Evil is not rationable norfunctionable, it is what does not have meaning, what hinders the world's transparency and intelligibility. The author assumes this in order to finally analyse the crisis of the subject and of metaphysks, the postmodern crisis of reason and of universal systems. His claim is that this new context, the one of feeble metaphysks, offers new opportunities to the Christian proposal, whereby it asserts at the same time the impossibility of theodicy as a speculative theory and the possibility of a meaningful and committed answer to what is the biggest of all meaningless things, evil. /// Hay una relación intrínseca entre la metafísica y la teodicea.

La teodicea busca superar el último obstáculo que se opone a esos sistemas, el mal en su triple dimensión de mal metafísico, físico y moral. El mal es lo no racionalizable, ni funcionalizable, lo que no tiene sentido, lo que impide la trasparencia e inteligibilidad del mundo.

Legislation on Disability/ Functional Diversity in Spain has experimented a great advance since 1982 to 2013, leaving the initial orientation, based on care and rehabilitation, toward another one based on rights and social inclusion as main objectives. However, this legislation has not been effective because in the same lap of time another transformation made it useless: the suppression of social rights that came from Keynesian politics and the progressive neoliberal ideology implantation. The evolution of People with Disability/ Functional Diversity labour (...) situation illustrates the imposition of what we name neoliberal “ableisment” over PFD labour rights. (shrink)

This paper is devoted to the study of some subvarieties of the variety Q of Q-Heyting algebras, that is, Heyting algebras with a quantifier. In particular, a deeper investigation is carried out in the variety Q subscript 3 of three-valued Q-Heyting algebras to show that the structure of the lattice of subvarieties of Q is far more complicated that the lattice of subvarieties of Heyting algebras. We determine the simple and subdirectly irreducible algebras in Q subscript 3 and we construct (...) the lattice of subvarieties lambda (Q subscript 3) of the variety Q subscript 3. (shrink)

This paper investigates the role that universities play in supporting social entrepreneurs (SEs) across their ecosystem. Adopting the resource-based view (RBV) approach, we argue that universities attract, mobilize, and deploy multiple resources that benefit SEs through four main mechanisms (i.e., teaching, research, outreach, and the development of partnerships). We use a qualitative approach of 62 semi-structured interviews and 8 focus groups in Ecuador, Bolivia, and Colombia. Our contribution shows that employing different resources and engaging in supportive activities of universities towards (...) SEs facilitate the development of university capabilities, such as an increased reputation, development of leadership skills for students and staff, and wider access to ecosystem resources that support other university activities related to teaching, research, and community outreach. The role that partnerships play in the development of these capabilities is fundamental, thanks to the different strategic alliances and mobilization of resources between universities and other actors while supporting SEs. This study contributes to our understanding of the role universities can play to intensify the nature of supportive ecosystems for SEs. This contribution is relevant not only to academics but also to practitioners, as this will shed light on the building, development, and scaling of a supportive ecosystem for SEs. (shrink)

Long noncoding RNAs have been described in cell lines and various whole tissues, but lncRNA analysis of development in vivo is limited. Here, we comprehensively analyze lncRNA expression for the adult mouse subventricular zone neural stem cell lineage. We utilize complementary genome-wide techniques including RNA-seq, RNA CaptureSeq, and ChIP-seq to associate specific lncRNAs with neural cell types, developmental processes, and human disease states. By integrating data from chromatin state maps, custom microarrays, and FACS purification of the subventricular zone lineage, we (...) stringently identify lncRNAs with potential roles in adult neurogenesis. shRNA-mediated knockdown of two such lncRNAs, Six3os and Dlx1as, indicate roles for lncRNAs in the glial-neuronal lineage specification of multipotent adult stem cells. Our data and workflow thus provide a uniquely coherent in vivo lncRNA analysis and form the foundation of a user-friendly online resource for the study of lncRNAs in development and disease. © 2013 Elsevier Inc.

Justo antes de la pandemia por COVID-19, la Organización Mundial de la Salud definió unas prioridades de trabajo para la década 2020-2030. Un grupo interdisciplinario de profesionales de la salud reflexiona sobre estas prioridades, determinando unas categorías de análisis y, desde una perspectiva bioética, analiza cada una de ellas, ve su pertinencia, algunos eventos causales, las implicaciones que pueden tener si no son enfrentadas adecuadamente y hace sugerencias sobre la forma de llevarlas a cabo. En esta primera entrega se analiza (...) el primer grupo de prioridades estratégicas: “poblaciones más sanas”. En las conclusiones se destaca la conveniencia de acometer cada una de ellas de una manera colaborativa, gubernamental y privada; de reestructurar el sector salud con base en estas prioridades, aprovechando la experiencia obtenida en la lucha contra el COVID-19. La relación del ser humano con el medio ambiente también debe cambiar, apelando a la responsabilidad humana por el cuidado del planeta. (shrink)

The aim of the present research was to assess elite student-athletes’ perception of the dual career during the lockdown caused by the coronavirus disease 2019 pandemic, compared with a group of elite student-athletes who could develop their dual career under normal conditions. A total of 150 elite athletes who were also undergraduate or postgraduate students self-completed the “Perceptions of dual career student-athletes ” questionnaire. From them, 78 did it during the mandatory lockdown period due to the state of emergency caused (...) by COVID-19 and 72 completed it in the previous year to Rio 2016 Olympic Games. The COVID-19 group was found to spend a significantly higher number of hours per week studying, while no significant differences were observed between groups in any training time variable. Student-athletes of the COVID-19 group showed better perception of whether their sport career could help them cope with their academic career and better general perception of remote learning and the use of tasks and videoconferencing as learning support tools. A lower percentage of athletes of the COVID-19 group than of the control group wished to continue with their sport career once they finished their studies. To conclude, student-athletes of the COVID-19 group show adaptations with regard to the organization of their studies and the importance they give to them and to the services provided by dual-career programs, compared with student-athletes from an ordinary pre-Olympic year. In general, student-athletes’ perception of the dual career is very positive. (shrink)

Notwithstanding the potential danger to security and privacy, sharing and publishing data has become usual in Data Science. To preserve privacy, de-identification methodologies guided by risk estimation have been designed. Two issues associated with classical risk metrics are, on the one hand, the adequacy of the metric and, on the other hand, its static nature. In this paper, we present metrics for estimating risk based on the emerging semantics provided by Formal Concept Analysis. The metrics are designed to estimate the (...) a priori risk of compromised data deletion. Furthermore, by applying specialized variable forgetting methods for association rules, it is shown how to reflect the effect of deleting attributes belonging to potentially dangerous quasi-identifier sets. Additionally, a study of the role of the risk metric in confidence-based reasoning for re-identification is presented. (shrink)

The syllogism and the predicate calculus cannot account for an ontological argument in Descartes' Fifth Meditation and related texts. Descartes' notion of god relies on the analytic-synthetic distinction, which Descartes had identified before Leibniz and Kant did. I describe how the syllogism and the predicate calculus cannot explain Descartes' ontological argument; then I apply the analytic-synthetic distinction to Descartes’ idea of god.

We study 944 shareholder proposals submitted to 343 U.S. firms on climate change issues during 2009–2022. We use logistic and two-stage regression to estimate the propensity for a firm to be targeted or subjected to a vote at the annual general meeting and, for voted proposals, the determinants of that vote. We also examine whether climate-related proposals affect investor returns and how they relate to firms’ future environmental performance and greenhouse gas emissions. Compared to a matched sample, we first find (...) that activists target larger, more carbon-intensive, and less R&D-active firms. Second, voting likelihood is higher for firms with repeated and operations-related proposals and lower pre-proposal environmental ratings. By contrast, disclosure-related proposals are likelier to be negotiated and withdrawn. Third, repeated and operations-related proposals receive higher votes in favor, whereas votes on carbon-intensive firms do not. Fourth, building on the theory that investors act as if they distinguish among the different shareholder proposals based on the expected cost to the firm, we find evidence to support this idea. We find that investors respond negatively to ex-ante costlier proposals, such as those that relate to emissions reduction and target carbon-intensive firms. Fifth, targets’ future environmental performance rating is almost twenty percent higher after a proposal than before compared to the matched sample, whereas emissions do not budge appreciably.

A widespread need to explain the behavior and outcomes of AI-based systems has emerged, due to their ubiquitous presence. Thus, providing renewed momentum to the relatively new research area of eXplainable AI (XAI). Nowadays, the importance of XAI lies in the fact that the increasing control transference to this kind of system for decision making -or, at least, its use for assisting executive stakeholders- already affects many sensitive realms (as in Politics, Social Sciences, or Law). The decision-making power handover to (...) opaque AI systems makes mandatory explaining those, primarily in application scenarios where the stakeholders are unaware of both the high technology applied and the basic principles governing the technological solutions. The issue should not be reduced to a merely technical problem; the explainer would be compelled to transmit richer knowledge about the system (including its role within the informational ecosystem where he/she works). To achieve such an aim, the explainer could exploit, if necessary, practices from other scientific and humanistic areas. The first aim of the paper is to emphasize and justify the need for a multidisciplinary approach that is beneficiated from part of the scientific and philosophical corpus on Explaining, underscoring the particular nuances of the issue within the field of Data Science. The second objective is to develop some arguments justifying the authors’ bet by a more relevant role of ideas inspired by, on the one hand, formal techniques from Knowledge Representation and Reasoning, and on the other hand, the modeling of human reasoning when facing the explanation. This way, explaining modeling practices would seek a sound balance between the pure technical justification and the explainer-explainee agreement. (shrink)

Three arguments summarize opposition to laws protecting LGBTQ+ persons from discrimination: (1) The pseudo-democratic argument (social change should be free of governmental coercion); (2) The clinical argument (homosexuality is an illness); (3) The choice argument (homosexuality is a choice). My purpose is to show the three are vulnerable to damaging objections. This article reflects conditions as they were in 1987 in the USA. For example, the expression LGBTQ+ had not been coined. My use of "gays and lesbians," then believed to (...) be inclusive, excluded a lot of people. (shrink)

SPANISH: Las parejas del mismo sexo tienen razón cuando dicen que negarles el matrimonio es discriminar contra ellas; pero otorgar el matrimonio a las parejas del mismo sexo sin dar a familias no conyugales los beneficios que el matrimonio provee remediaría la injusticia hacia las primeras sin subsanar la iniquidad hacia las segundas. Crear una sociedad que favorece solo una opción para reconocer las relaciones de serio compromiso no debe ser la meta de un movimiento progresista. -/- ENGLISH: Same-sex couples (...) are right when they say that denying them marriage is discriminating against them; but granting marriage to same-sex couples without giving non-marital families the benefits marriage provides would remedy the injustice towards the former without correcting the iniquity towards the latter.
