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.

Socially responsible human resource management (SR‐HRM) is becoming increasingly important for academics and managers. The interface between HRM and corporate social responsibility (CSR) is the subject of analysis in this article. It adopts a contextual perspective to analyze whether the institutional context influences the implementation of socially responsible HRM (SR‐HRM). Considering the differences in the national institutional contexts across Europe, this study explores the different models of SR‐HRM in that region. The research is focused on a sample of 153 companies (...) headquartered in Germany, Spain, Sweden, and the United Kingdom. The findings evidence the influence exerted by the national institutional context on the implementation of SR‐HRM. Differences among country clusters suggest the existence of different models of SR‐HRM in Europe. However, these models do not correspond to the blocks on HRM or on CSR identified by the literature but instead provide a novel categorization. (shrink)

Providing an inclusive and quality education for all contributes toward the Sustainable Development Goals of the United Nations. High-quality learning environments based on what works in education benefit all students and can be particularly beneficial for children with disabilities. This article contributes to advance knowledge to enhance the quality of education of students with disabilities that are educated in special schools. This research analyses in which ways, if any, interactive learning environments can be developed in special schools and create better (...) learning opportunities for children with disabilities. A case study was conducted with students with disabilities (N = 36) and teaching staff in a special school, involving interviews and focus groups. We argue that rethinking the learning context by introducing instruction models based on interaction benefit children with disabilities and provide high-quality learning and safe and supportive relationships for these students, thereby promoting their educational and social inclusion.

This paper is concerned with certain ontological issues in the foundations of geographic representation. It sets out what these basic issues are, describes the tools needed to deal with them, and draws some implications for a general theory of spatial representation. Our approach has ramifications in the domains of mereology, topology, and the theory of location, and the question of the interaction of these three domains within a unified spatial representation theory is addressed. In the final part we also consider (...) the idea of non-standard geographies, which may be associated with geography under a classical conception in the same sense in which non-standard logics are associated with classical logic.

Después de haber tratado el tema del desenlace del discipulado de Simón Pedro a la luz de Jn 21,15-19 en anterior artículo, quedaba pendiente realizar lo propio con respecto al personaje del discípulo amado. La primera sección del epílogo del evangelio, asocia, en efecto, estas dos figuras que interactúan en sinergia para reconocer al Resucitado en su tercera manifestación. Y la finalidad de dicha manifestación consiste en proveer a las necesidades de la comunidad de discípulos en medio de los desafíos (...) inéditos del tiempo post-pascual. El presente artículo desarrolla la especificidad del seguimiento del discípulo amado que, junto con el de Pedro, constituirá parte fundamental de esa provisión necesaria para la vida y misión de la naciente Iglesia.

La evidencia de un desenlace para el discipulado de Pedro en Jn 21, coherente con el cuerpo del relato, denota la unidad tanto literaria como teoló-gica del cuarto evangelio : la promesa de un futuro seguimiento que había quedado pendiente en Jn 13,36 llega a su cumplimiento en Jn 21,19; pero también, el enigmático sobrenombre que impone Jesús a Simón, hijo de Juan, al inicio del relato solo halla dilucida-ción en Jn 21,15-17. Sin embargo, al mismo tiempo, dicha evidencia des-tacará (...) una novedad importante res-pecto al desarrollo literario anterior: el discípulo amado comunica ahora su ciencia, su conocimiento intui-tivo del Señor a Simón Pedro. Tal modo de actuar carece de paralelo a lo largo del cuerpo del relato evangélico, indicando, desde el plano diacrónico, un nuevo esta-dio en el camino de reflexión teoló-gica de la comunidad joánica.

Reasons-first theorists claim that facts about reasons for attitudes are normatively primitive, and that all other normative facts ultimately reduce to facts about reasons. According to their view, for example, the fact that something is good ultimately reduces to facts about reasons to favour it. I argue that these theories face a challenging dilemma due to the normativity of arational lifeforms, for instance the fact that water is good for plants. If all normative facts are, ultimately, facts about reasons for (...) attitudes, then reasons-first theorists must either (a) show that these facts do reduce to facts about reasons, or (b) concede that they do not and, instead, show that this is not a problem for their view. Both options, however, are riddled with difficulties—or so I will try to argue. (shrink)

El autor analiza algunos aspectos de los debates sobre la democracia en la llamada transición de los años ̓80, para advertir sobre la preeminencia que adquirieron las disposiciones procedimentales y representativas —elevadas a condición metanormativa— y la conceptualización de la política como producción de consensos. Esas orientaciones impidieron una recuperación de las experiencias democráticas que la dictadura intentó cancelar, y fueron incapaces de poner en foco las figuras de subjetividad que el terror estatal y el neoliberalismo produjeron en tanto intervenciones (...) sobre las tramas sociales. Finalmente, el autor se detiene brevemente en algunas experiencias políticas democratizadoras, en tanto formas de aparición de los pueblos en estos últimos 40 años. (shrink)

Husserl proceeds to show how a world-representation emerges from our world-experience, and how an idea of the world plays a role in the expansion of world-representations. He also draws our attention to the appropriation of other world-representations in a process of adjustment and compensation leading to intersubjective world-representations, and offers an analysis of the status of world-representations within transcendental phenomenology. In this article I will underline the relevance of Husserl’s concept of horizonedness to the characterization of the three levels of (...) world-experience, worldrepresentation, and the world as an idea. In getting clear on this relevance several points must be emphasized. (shrink)

Volume 1 of Politics, a work in constructive social theory. Newly available, the complete work of Politicsa program for a comprehensive progressive alternative to the dominant ideologies of social democracy and neo-liberalismfrom one of the worlds leading social and political thinkers. False necessity is the central theme in the three-volume series Politics. It presents both a way of explaining society and a program for changing it. The explanation develops a radical alternative to Marxism, showing how we can account for established (...) social arrangements without denying their contingency or our freedom. The program offers a progressive alternative to the now-dominant ideological conceptions of neoliberalism and social democracy: a set of institutional innovations that would democratize markets, deepen democracy and empower individuals. For this new edition, Unger has written a comprehensive introduction that explores the limits of our understanding of society and our practice of politics, and reconsiders proposals contained in the book as special cases of a larger family of untried political possibilities.

The present investigation aims to elucidate the presence of myth in the work of Eduardo Nicol. This inquiry of course, is something not thought about, since the author in question from the beginning of his philosophy has recognized that the path of thought is beyond myth, that is, it is nuanced by reason and by conceptual rigor. In other words, for him philosophy is about what is phenomenologically accessible and about what is rationally intelligible. Precisely for this reason, one of (...) the names with which Nicol's philosophy is known is under the name of "Metaphysics of expression" by virtue of the fact that what is given is commonly acquired through an expressive or communicative act. However, and despite this conceptual position, the fact is that the presence of myth can be found at the very heart of this philosopher’s philosophy. It should be noted that there is a particular myth that prevails in the clearing of his work, namely the myth of the androgyne. Through this myth it is possible to elucidate the origin of man and the original idea about symbol. (shrink)
