Recommending the identity of bidders in public procurement auctions has a significant impact in many areas of public procurement, but it has not yet been studied in depth. A bidders recommender would be a very beneficial tool because a supplier can search appropriate tenders and, vice versa, a public procurement agency can discover automatically unknown companies which are suitable for its tender. This paper develops a pioneering algorithm to recommend potential bidders using a machine learning method, particularly a random forest (...) classifier. The bidders recommender is described theoretically, so it can be implemented or adapted to any particular situation. It has been successfully validated with a case study: an actual Spanish tender dataset which has 102,087 tenders from 2014 to 2020 and a company dataset which has 1,353,213 Spanish companies. Quantitative, graphical, and statistical descriptions of both datasets are presented. The results of the case study were satisfactory: the winning bidding company is within the recommended companies group, from 24% to 38% of the tenders, according to different test conditions and scenarios.

Automatic public malware analysis services provide controlled, isolated and virtual environments to analyse malicious software samples. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment; when an analysis environment is detected, malware behaves as a benign application or even shows no activity. In this work, we present an empirical study and characterization of automatic PMAS, considering 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis (...) environments; the lower the unlikeability of these features, the easier for us to fingerprint the analysis service they belong to. Finally, we propose a method for these analysis services to counter or at least mitigate our proposal. (shrink)

El presente monográfico de Recerca titulado «Los nuevos discursos del management: contribuciones desde una perspectiva crítica», se compone de siete artículos de investigación y dos recensiones. A través de los diferentes escritos se pretende realizar un recorrido por el estado actual de los discursos del management y sus repercusiones no solo en el mundo del trabajo, sino en el grueso de la sociedad desde una perspectiva crítica. Así pues, a lo largo de las siguientes páginas el/la lector/a podrá transitar por (...) los diferentes discursos que hoy en día caracterizan el espacio social. Nos referimos a marcos generales de sentido como el individualismo y la descolectivización de lo social, pero también a cuestiones más concretas como el emprendimiento y la precariedad; todos ellos componentes que conforman el escenario al que nos estamos remitiendo en todo momento, esto es, el del discurso neoliberal o el «nuevo espíritu del capitalismo» (Boltanski y Chiapello, 2002).

Nuestro objetivo es mostrar que una caracterización adecuada de las locuciones modales del lenguaje natural depende fundamentalmente de una correcta descripción de sus propiedades lógicas. Mostramos cómo los análisis escalares en pragmática fracasan porque siguen la lógica modal estándar al tratarlos como operadores preposicionales. Esto produce contradicciones, ya que, en sentido estricto, el estatus lógico de la locución modal es el mismo que el de la proposición simple. Estas expresiones invocan la presencia del hablante y la evidencia que respalda a (...) su afirmación, y tienen por lo tanto un carácter eminentemente deíctico/pragmático.It is our aim in this article to show that an adequate characterization of the interpretation of modally qualified utterances in natural language depends crucially on a correct description of their logical properties. We show that pragmatic analyses in terms of scales fail because they rely on the standard treatment of these expressions in modal logic as operators, and this makes the wrong predictions since, in a strict sense, the logical status of the modally- qualified utterance is the same as that of the bare proposition. We argue that these expressions directly invoke the presence of the speaker and act as indexes to sets of assumptions s/he is relying on as evidence for his/her assertion. (shrink)

Scot's thought in he Spanish Medieval Philosophy. Duns Scot's philosophical doctrine got a great development in the Iberian Peninsula, especially in the Kingdom og Aragon, during 14th-16th centuries. But not all the Spanish Scotists were faithfull interpreters of Scot's thought, as it happened to Antonio Andres, the most representative philosopher of the Spanish Scotism.

An essential requirement for increasing human confidence in computer systems is knowing an event’s origin. Therefore, it is necessary to have an efficient method to record such information. It is especially challenging in robotics, where unexpected behaviours can have unpredictable consequences, endangering the interests of people or even their safety. Furthermore, to analyse an incident’s cause or anticipate future behaviours, we must identify the events that cause a specific action. Although it is common to use logging systems for such purposes, (...) issues such as partial recording of events, unhelpful data or the impact on robot performance suggest conceiving new accountability solutions that assist when determining the responsible entities or the provenance of specific information. This paper presents a general-purpose approach to developing an accountability system for autonomous robots. It consists of four main components: a system event logger, a message producer, a distributed event streaming platform and a database. Our proposal is completely decoupled from the monitored system and allows real-time analysis, improving flexibility, besides system protection and transparency. Finally, the need to reduce the impact of the audit process and logging tasks on robot performance has promoted the development of different assessment scenarios to determine the best strategy for providing accounting services.

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

El libro Las generaciones que llegaron tarde presenta los resultados de un trabajo sobre los usos, las estrategias y las percepciones de las generaciones mayores en relación a las tecnologías de la información y de la comunicación. Las apropiaciones de los y las mayores en los ámbitos laboral, relacional y familiar, así como en el ocio, son objeto de análisis a partir de entrevistas en profundidad. Entre los principales resultados destaca el que, a pesar de la gran capacidad de adaptación (...) de las personas mayores a los nuevos entornos digitales, la sociedad informacional sigue avanzando a ritmos desiguales: mientras penetra y media en buena parte de las dinámicas sociales, sigue dejando en los márgenes a una parte de la población perteneciente a las generaciones de más edad.

Resumen: En el marco del estudio de los discursos gerenciales, se destacan en el presente texto algunas de las aportaciones de Medina-Vicent, especialmente el análisis de los procesos de individualización y despolitización de mensajes que entroncarían con las reivindicaciones del feminismo. En este contexto, se propone la incorporación del concepto foucaultiano de dispositivo para el estudio de los elementos que contribuyen a la difusión de los discursos gerenciales. Este concepto podría ser de utilidad en la investigación empírica, proporcionando una herramienta (...) conceptual para estudiar como un sistema homogéneo de relaciones de saber y poder los distintos elementos que conformarían el dispositivo gerencial.: Within the framework of the study of managerial discourses, this text highlights some of the contributions of Medina-Vicent, especially the analysis of the processes of individualization and depoliticization of messages that are linked to the claims of feminism. In this context, the incorporation of the Foucauldian concept of dispositif is proposed for the study of the elements that contribute to the diffusion of managerial discourses. This concept could be useful in the empirical analysis, as well as providing a conceptual tool to study the different elements that make up the managerial dispositif as a homogeneous system of knowledge and power relations.

Impairments in pragmatic abilities, that is, difficulties with appropriate use and interpretation of language – in particular, non-literal uses of language – are considered a hallmark of Autism Spectrum Conditions (ASC). Despite considerable research attention, these pragmatic difficulties are poorly understood. In this paper, we discuss and evaluate existing hypotheses regarding the literalism of ASC individuals, that is, their tendency for literal interpretations of non-literal communicative intentions, and link them to accounts of pragmatic development in neurotypical children. We present evidence (...) that reveals a developmental stage at which neurotypical children also have a tendency for literal interpretations and provide a possible explanation for such behaviour, one that links it to other behavioural, rule-following, patterns typical of that age. We then discuss extant evidence that shows that strict adherence to rules is also a widespread feature in ASC, and suggest that literalism might be linked to such rule-following behaviour. (shrink)

There is an ongoing debate about the meaning of lexical words, i.e., words that contribute with content to the meaning of sentences. This debate has coincided with a renewal in the study of polysemy, which has taken place in the psycholinguistics camp mainly. There is already a fruitful interbreeding between two lines of research: the theoretical study of lexical word meaning, on the one hand, and the models of polysemy psycholinguists present, on the other. In this paper I aim at (...) deepening on this ongoing interbreeding, examine what is said about polysemy, particularly in the psycholinguistics literature, and then show how what we seem to know about the representation and storage of polysemous senses affects the models that we have about lexical word meaning.

Las trayectorias del arte caribeño, luego de la Segunda Guerra Mundial, experimentan profundas transformaciones en sus prácticas creativas y modos de comprensión cultural. Las complejas realidades sociales y políticas en las islas del Caribe hispano condujeron a un punto de giro en los procesos regionales, una transformación del campo del arte y replanteamientos de los discursos periféricos desde las manifestaciones, los temas de interés y el rol del artista en la sociedad. La fotografía, y especialmente aquella procedente de espacios periféricos (...) en las lógicas internacionales del arte, aportaron los iconos más contestatarios del momento. Los símbolos culturales de una nueva voz, que responde a un pensamiento emancipatorio y descolonizador, se expresan en la construcción de un discurso visual de paradigmas éticos y libertarios. Los lenguajes más renovadores de la época apelan a una base fotográfica de trasfondo por la relación entre la inmediatez y la pregnancia de la imagen, o la inherente reproductibilidad que propicia una función comunicativa más efectiva.

This article focuses on Stuart Hall’s reading of Louis Althusser’s main theoretical works. Since the early 1970s, Hall has undertaken a critical confrontation with Althusser’s ‘structural Marxism’, rescuing those useful concepts to think cultural difference and identity, without failing to criticize his ‘superstructuralist’ interpretation of Marx. However, what Hall will retain as Althusser’s most important contribution is, above all, his theory of ideology. In this context, I follow an idea formulated by Hall that could be read as summarizing the theoretical (...) and political scope of Althusser’s contribution to Cultural Studies: ‘he enabled me to live in and with difference’. By complicating classical interpretations schemes in the Marxist tradition, Hall’s Althusser may be read as a ‘thinker of difference’ who opens up a whole research program to reconsider class conflicts as traversed (or ‘overdetermined’) by gender, racial or colonial conflicts.

Teaching mathematics and improving mathematics competence are pending subjects within our educational system. The PEIM (Programa Evolutivo Instruccional para Matemáticas), a constructivist intervention program for the improvement of mathematical performance, affects the different agents involved in math learning, guaranteeing a significant improvement in students’ performance. The program is based on the following pillars: (a) students become the main agents of their learning by constructing their own knowledge; (b) the teacher must be the guide to facilitate and guarantee such a construction (...) by being a great connoisseur of the fundamental aspects of the development of the child’s mathematical thinking; (c) the mathematical contents must be sequenced in terms of the complexity and significance for the student as well as contextualized at all times; and (d) the classroom must have a constructivist climate highlighting cooperative work among students. The implementation of PEIM along with the empirical evaluation conducted in several centers in Madrid and Zaragoza (Spain) confirm how students improve their mathematical competence. Both first- and second-grade students in elementary education were far more effective in solving problems, highlighting the use of more advanced strategies in their resolution and a lower incidence of conceptual errors. Moreover, it was possible to verify how the students proving greater difficulty, experienced an evolution in learning similarly to those who did not present it. The program provides customized education to allow the teacher to know at all times how he should be more influential on the students’ learning through mathematical profiles. Both teaching practice and teachers were observed, being that of the experimental group more prone to analyzing processes and allowing the construction of knowledge by students, due to their psycho-developmental training. As a result, we found several improvements through the implementation of the program that may serve, for upcoming years, as a basis for the necessary changes in the teaching of mathematics. (shrink)

The goal of this piece is to put some pressure on Brian O’Shaughnessy’s claim that perceptual experiences are necessarily mental processes. The author targets two motivations behind the development of that view. First, O’Shaughnessy resorts to pure conceptual analysis to argue that perceptual experiences are processes. The author argues that this line of reasoning is inconclusive. Secondly, he repeatedly invokes a thought experiment concerning the total freeze of a subject’s experiential life. Even if this case is coherent, however, it does (...) not show that perceptual experiences are processes. (shrink)

In most domains of human life, we are willing to accept that there are experts with greater knowledge and competencies that distinguish them from non-experts or laypeople. Despite this fact, the very recognition of expertise curiously becomes more controversial in the case of “moral experts”. Do moral experts exist? And, if they indeed do, are there ethical reasons for us to follow their advice? Likewise, can emerging technological developments broaden our very concept of moral expertise? In this article, we begin (...) by arguing that the objections that have tried to deny the existence (and convenience) of moral expertise are unsatisfactory. After that, we show that people have ethical reasons to ask for a piece of moral advice in daily life situations. Then, we argue that some Artificial Intelligence (AI) systems can play an increasing role in human morality by becoming moral experts. Some AI-based moral assistants can qualify as artificial moral experts and we would have good ethical reasons to use them. (shrink)
