Sin ningún afán polémico, el presente artículo aspira a presentar algunos rasgos de Menéndez Pelayo, que puedan legitimar su caracterización como filósofo ; faceta esta, quizá, la menos vistosa de este gran historiador y crítico, incansable lector y escritor fecundo. Rastreando sus obras más específicas sobre el particular, se expone su pensamiento al respecto, no solo para saber como entiende los conceptos filosóficos más básicos, sino también para ver la posibilidad de enmarcarlo en alguna corriente filosófica que admita su clasificación.
Background. The study of entrepreneurial activity has undergone intense development in recent decades. Traditionally this topic has been addressed from three approaches: economic, sociological and psychological. In the study of enterprising personality, two fundamental perspectives stand out: the use of general personality traits, like the Big Five, and the use of more specific traits related to entrepreneurial spirit, such as self-efficacy, autonomy, innovation, optimism, and others. The objective of this study is to provide validity evidence for a new instrument for (...) measuring eight specific dimensions of entrepreneurial personality (BEPE). Method. The sample was composed of 1,170 adults from the general population (59.9% women). The average age was 42.34 years with a standard deviation of 12.96. Of the sample, 13% were self-employed. Internal factorial structure and reliability of BEPE were examined. The relationships with other variables and the discriminative capacity of the BEPE between different groups of workers were analyzed. Results. First order factor analyses show the essential unidimensionality of each of the eight proposed sub-scales, with factorial weights ranging between 0.341 and 0.825. A second-order factor analysis was carried out, obtaining a general dimension of entrepreneurial personality. With regards to reliability, the eight BEPE sub-scales gave high alpha coefficient values, between 0.825 and 0.899, as did the total battery (0.97). BEPE sub-scales show a high canonical correlation with the Big Five personality factors (.795), and with the sub-scales of the Measure of Entrepreneurial Talents and Abilities questionnaire (.815). Conclusions. The BEPE questionnaire for the evaluation of the eight fundamental specific dimensions of the entrepreneurial personality presents adequate psychometric properties. Its relationships with other measures of personality traits are in line with what is expected. Therefore, the BEPE is a new measurement instrument that can be used with confidence both in the applied field and in research. (shrink)
We discuss the axiomatization of generalized consequence relations determined by non-deterministic matrices. We show that, under reasonable expressiveness requirements, simple axiomatizations can always be obtained, using inference rules which can have more than one conclusion. Further, when the non-deterministic matrices are finite we obtain finite axiomatizations with a suitable generalized subformula property.
We consider a 2-valued non-deterministic connective \({\wedge \!\!\!\!\!\vee }\) defined by the table resulting from the entry-wise union of the tables of conjunction and disjunction. Being half conjunction and half disjunction we named it _platypus_. The value of \({\wedge \!\!\!\!\!\vee }\) is not completely determined by the input, contrasting with usual notion of Boolean connective. We call non-deterministic Boolean connective any connective based on multi-functions over the Boolean set. In this way, non-determinism allows for an extended notion of truth-functional connective. (...) Unexpectedly, this very simple connective and the logic it defines, illustrate various key advantages in working with generalized notions of semantics (by incorporating non-determinism), calculi (by allowing multiple-conclusion rules) and even of logic (moving from Tarskian to Scottian consequence relations). We show that the associated logic cannot be characterized by any finite set of finite matrices, whereas with non-determinism two values suffice. Furthermore, this logic is not finitely axiomatizable using single-conclusion rules, however we provide a very simple analytic multiple-conclusion axiomatization using only two rules. Finally, deciding the associated multiple-conclusion logic is \(\mathbf {coNP}\) -complete, but deciding its single-conclusion fragment is in \({\mathbf {P}}\). (shrink)
College cheating is prevalent, with rates ranging widely from 9 to 95% (Whitley, 1998). Research has been exclusively conducted with enrolled college students. This study examined the prevalence of cheating in a sample of college alumni, who risk less in disclosing academic dishonesty than current students. A total of 273 alumni reported on their prevalence and perceived severity of 19 cheating behaviors. The vast majority of participants (81.7%) report having engaged in some form of cheating during their undergraduate career. The (...) most common forms of cheating were “copying from another student's assignment” and “allowing others to copy from your assignment.” More students reported cheating in classes for their major than other classes. Males and females cheated at the same rates in classes for their major, and males reported higher rates of cheating than females in nonmajor classes. Respondents reported that their top reasons for cheating were “lack of time” and “to help a friend.”. (shrink)
As fronteiras são um tema conceitualmente polissêmico e um objeto multidisciplinar. Estudos que tratam desse tema são de grande valia para os campos da Geografia, Relações Internacionais, Direito, História, entre outros. Visando contribuir com esse debate, essa resenha apresenta uma visão do livro Formação das Fronteiras Latino-Americanas, que caracteriza-se como uma importante contribuição, com diversas questões diferenciadas na discussão realizada.
We show that for an arbitrary logic being locally tabular is a strictly weaker property than being locally finite. We describe our hunt for a logic that allows us to separate the two properties, revealing weaker and weaker conditions under which they must coincide, and showing how they are intertwined. We single out several classes of logics where the two notions coincide, including logics that are determined by a finite set of finite matrices, selfextensional logics, algebraizable and equivalential logics. Furthermore, (...) we identify a closure property on models of a logic that, in the presence of local tabularity, is equivalent to local finiteness. (shrink)
Epistemology or the theory of knowledge is one of the cornerstones of analytic philosophy, and this book provides a clear and accessible introduction to the subject. It discusses some of the main theories of justification, including foundationalism, coherentism, reliabilism, and virtue epistemology. Other topics include the Gettier problem, internalism and externalism, skepticism, the problem of epistemic circularity, the problem of the criterion, a priori knowledge, and naturalized epistemology. Intended primarily for students taking a first class in epistemology, this lucid and (...) well-written text would also provide an excellent introduction for anyone interested in knowing more about this important area of philosophy.

In this paper we aim to defend a version of the thesis of “extended mind” against the criticism of some authors that consider that the “extracraneal” devices cannott acomplish the requirements that the components of mental processes must meet. We propose a quality of integration as a criterion to be a mental process, and we consider that, in some situations, external devices can be considered as meeting this criterion.
Francisco de Vitoria, no por su catalogación como teólogo, deja de ser auténtico filósofo; no por haber vivido en el siglo xvi, se encuentra desvinculado de la temática más candente de nuestra actualidad; no por vestir unos hábitos religiosos y vivirenmarcado en un régimen imperialista e inquisitorial, se encontró maniatado o coaccionado en sus ideas y pensamiento. En algunos puntos se encontró, incluso, más avanzado que nosotros mismos. Y. en todo caso, como asegura James Brown Scott, "la escuela moderna del (...) Derecho Internacional surgió a la vida" gracias a que hubo un "primero que expuso los principios que deberían regir"; y ése no es otro que Francisco de Vitoria. (shrink)
La doctrina de Vitoria con respecto a que los derechos humanos —naturales o «de gentes», no importa si al margen de la fe y el cristianismo—, están muy por encima del poder y la jurisdicción del Papa o el Emperador, se infiltré de tal forma en el modo de pensar posterior, que, a pesar de haber olvidado al propio Vitoria como su fundador o, al menos, su principal impulsor, prevaleció en la mente de los grandes pensadores posteriores y se va (...) viendo calcada tanto en la realidad histórica o las relaciones sociales de nuestro tiempo, como en la propia Constitución de las diferentes democracias actuales.

A pesar de que el nombre de Francisco de Vitoria no aparece en los tratados y autores del siglo xvm, no por eso su doctrina fue ignorada. Muy por el contrario, sus tesis, no obstante ser atribuidas a Hugo Grocio, son mantenidas y aceptadaspor autores tan importantes y destacados como Locke o Kant.The fact that the name of Francisco de Vitoria does not appear in the treatises and among the authors of the 18th century does not mean that his doctrine (...) was unknown. On the contrary, his thesis although credited to Grotius were known. On the contrary, his thesis although credited to Grotius were known and accepted by many important authors such as Locke or Kant.

This paper focuses on order-preserving logics defined from varieties of distributive lattices with negation, and in particular on the problem of whether these can be axiomatized by means Hilbert-style calculi that are finite. On the negative side, we provide a syntactic condition on the equational presentation of a variety that entails failure of finite axiomatizability for the corresponding logic. An application of this result is that the logic of all distributive lattices with negation is not finitely axiomatizable; we likewise establish (...) that the order-preserving logic of the variety of all Ockham algebras is also not finitely axiomatizable. On the positive side, we show that an arbitrary subvariety of semi-De Morgan algebras is axiomatized by a finite number of equations if and only if the corresponding order-preserving logic is axiomatized by a finite Hilbert-style calculus. This equivalence also holds for every subvariety of a Berman variety of Ockham algebras. We obtain, as a corollary, a new proof that the implication-free fragment of intuitionistic logic is finitely axiomatizable, as well as a new corresponding Hilbert-style calculus. Our proofs are constructive in that they allow us to effectively convert an equational presentation of a variety of algebras into a Hilbert-style calculus for the corresponding order-preserving logic, and vice versa. We also consider the assertional logics associated to the above-mentioned varieties, showing in particular that the assertional logics of finitely axiomatizable subvarieties of semi-De Morgan algebras are finitely axiomatizable as well.

Ontology languages for the Semantic Web have their strengths and weaknesses, in particular in the light of deploying them for biological and medical information systems. We survey and compare the Description Logics-based OWL languages, and the DL-Lite and DLR families of languages. Language choices that an ontology developer has to make are, among others, expressivity with n-ary relations (where n > 2) and more role properties versus ontology usage for data-intensive tasks. Guidelines are suggested to facilitate choosing the language best (...) fitted for a task. (shrink)
Palace of the End is a dense triptych of monologues exploring alternative narratives - albeit based in real facts - behind the events and the headlines surrounding the war in Iraq. Borrowing its title from the former royal palace where Saddam Hussein’s torture chamber was located, Thompson’s docudrama is structured as a chain of monologues telling three real-life stories set in the context of the war in Iraq. The play conveys three unconventional interpretations of the realities of war: that of (...) a young American soldier convicted for her misconduct at Abu Ghraib, the prison that stands as one of the most controversial symbols of the American-led Iraq invasion; a British scientist and weapons inspector who denounces what he understands as the false arguments given by his country’s leaders for engaging in a distant war; and an Iraqi mother whose life was shattered firstly by Saddam Hussein’s authoritarian regime, and later by the American first Gulf War. Each story is an enthralling and gut-wrenching reflection of one of the contemporary world’s most studied and controversial conflicts. The play gives voice to three different kinds of war victims, insofar as their political subjectivities and their moral conundrums are concerned. (shrink)
We show the first examples of recursively enumerable (even decidable) two-dimensional products of finitely axiomatisable modal logics that are not finitely axiomatisable. In particular, we show that any axiomatisation of some bimodal logics that are determined by classes of product frames with linearly ordered first components must be infinite in two senses: It should contain infinitely many propositional variables, and formulas of arbitrarily large modal nesting-depth.
