Let Q be an equivalence relation whose equivalence classes, denoted Q[x], may be proper classes. A function L defined on Field(Q) is a labelling for Q if and only if for all x,L(x) is a set and L is a labelling by subsets for Q if and only if BG denotes Bernays-Gödel class-set theory with neither the axiom of foundation, AF, nor the class axiom of choice, E. The following are relatively consistent with BG. (1) E is true but there (...) is an equivalence relation with no labelling.(2) E is true and every equivalence relation has a labelling, but there is an equivalence relation with no labelling by subsets.

En este capítulo se analiza la figura de la obtención vegetal: su alcance, dimensión, requisitos y caracterización frente a otros derechos de propiedad intelectual, para así abordar su ámbito de protección y su tratamiento en el ámbito internacional. Se pretende en este sentido plantear que la tendencia regulatoria en materia de obtenciones vegetales en Colombia no sólo va en contravía de los intereses de los pueblos indígenas, sino además de su patrimonio colectivo que les ha garantizado una gran diversidad que (...) hoy por hoy es sustento de su alimentación. Con lo anterior se lleva a cabo un singular esfuerzo para tratar de forma comprensiva este asunto, buscando la primacía del consentimiento libre, previo e informado de las comunidades potencialmente afectadas.

We prove that it is not possible to define an appropriate notion of rank in set theories without the axiom of foundation.

En este capítulo se estudia la facultad a prevención contenida en la Ley 1333 de 2009, para analizar la forma en la que el derecho ambiental ha venido construyendo una dogmática y reglas propias, escapando de la tradición del derecho administrativo, así como creando la dogmática propia necesaria para lograr su independencia y consolidación como un área autónoma de la disciplina jurídica. Al respecto, en este ejercicio de reflexión es posible ver cómo la figura aparte de estar diseñada por fuera (...) de la teoría general del acto administrativo, también posee particularidades que la hacen única dentro del ordenamiento jurídico colombiano.

The present study focuses on a grammatical category called evidentiality. The primary meaning of evidentiality is concerned with information source. That is, it expresses whether something has been seen, heard or inferred. The aim here is to conduct a conceptual study of evidentiality in which use is made of formal tools. The fundamental intuition is that the distinction between ‘evidence’as ‘proof’and ‘evidentiality’as ‘to do with proof’is a crucial one. Evidentiality is a dynamic notion to be analysed through the use of (...) knowledge by the agents, a knowledge in action, which involves an in-coming state and an out-coming state that is typical of the transmission of information. We propose our own approach in which the dynamics of knowledge in action is grasped in the context of a dynamic epistemic logic. (shrink)

The main objective of this article is to analyze the cognitive level of the activities in History textbooks in Spain, England, and Portugal in the transition stage from Primary to Secondary Education (11–13 years), according to the country of origin, typology, and the concepts and disciplinary contents included. The design of this research is quantitative, descriptive, and cross-sectional. The non-probabilistic sample consists of 6,561 activities contained in 27 school textbooks from Spain, England, and Portugal. Descriptive and contrast analyses have been (...) carried out using parametric tests. The results indicate that textbooks from Spain and Portugal mainly include activities situated between a basic and intermediate cognitive level while in England, the cognitive level of activities is medium or high. The ANOVA and TukeyBtests show significant differences between the cognitive level required in the activities and the typology of exercises, the concepts, and historical contents worked on. The activities with higher cognitive level correspond to those of creation and essays, the exercises that work on empathy and historical relevance, and that contain activities of social and economic history. In contrast, the activities with the lowest cognitive level are short questions and objective tests, those that work on first-order concepts (data and concrete facts), and those on the History of Art. The conclusion is that there is a need for a balanced presence of first-order content and historical thinking skills, the application in the classroom of a more active student-centered methodology, and the teachers’ conception of history teaching that prioritizes historical skills.

A fluent economical collaboration between countries is a major need. European flows of trade and people are supported by efficient connections between main localities from a geographic region, in many cases overriding national borders. This paper introduces three traveling salesmen problem instances based on freely available geographic coordinates of the main cities of France, Portugal and Spain. These instances are unified, generating other four larger instances: three with all pairs of countries and one instance with the settlements from all the (...) three countries. The study includes an analysis of quality of solutions for a version of branch & cut algorithm and some hybrid heuristics including the Lin–Kernighan algorithm. $Bor\mathring{u}vka$, Quick$Bor\mathring{u}vka$ and Greedy algorithms are also used in the hybrid approaches in order to obtain a potential beneficent initial solution for the Lin–Kernighan algorithm. Concorde solver, nowadays state-of-the-art exact software, together with the already mentioned algorithms, is used to test and furthermore analyze the new TSP instances. Some results are represented using online services such as Google Maps, showing the potential integration of the Concorde’s optimum results into commercial routing applications. The very good results provided by the Lin–Kernighan method allow its usage for real medium-sized routing instances. (shrink)

Meeting the security requests in transportation is nowadays a must. The intelligent transport systems represent the support for addressing such a challenge, due to their ability to make real-time adaptive decisions. We propose a new variant of the travelling salesman problem integrating security constraints inspired from ITSs. This optimization problem is called the secure TSP and considers a set of security constraints on its integer variables. Similarities with fuzzy logic are presented alongside the mathematical model of the introduced TSP variant.

Research biobanks are heterogeneous and exist to manage diverse biosample types with the goal of facilitating and serving biomedical discovery. The perspectives of biobank managers are reviewed, and the perspectives of two biobank directors, one with experience in institutional biobanks and the other with national cooperative group banks, are presented. Most research biobanks are not designed, nor do they have the resources, to return research results and incidental findings to participants or their families.

One of the most tantalizing questions about the interpretation of Quantum Theory is the objective vs. subjective meaning of quantum states. Here, by focusing on a typical EPR experiment upon which a selection procedure is performed on one side, we will confront the fully epistemic view of quantum states with its results. Our statement is that such a view cannot be considered complete, although the opposite attitude would also pose well-known problems of interpretation.

The traditional “realist” conception of physics, according to which human concepts, laws and theories can grasp the essence of a reality in our absence , seems incompatible with quantum formalism and it most fruitful interpretation. The proof rests on the violation by quantum mechanical formalism of some fundamental principles of the classical ontology. We discuss if the conception behind Einstein’s idea of a reality in our absence, could be still maintained and at which price. We conclude that quantum mechanical formalism (...) is not formulated on those terms, leaving for a separated paper the discussion about the terms in which it could be formulated and the onto-epistemological implications it might have.

O presente artigo tem por objectivo, em primeiro lugar, mostrar os diversos caminhos através dos quais a sociedade contemporânea tem progressivamente vindo a descobrir o problema ecológico. Num segundo passo, o artigo procede a uma análise das raízes histórico-culturais da redução da natureza a objecto de exploração por parte do ser humano, bem como dos diferentes modos mediante os quais este se relaciona com aquela, sublinhando de modo particular as consequências para o meio ambiente de um uso descontrolado da técnica (...) na transformação do mesmo. Finalmente, num terceiro momento, o autor analisa em que medida a filosofia, sob pressão da crise ecológica, está desenvolvendo um novo paradigma hermenêutico no qual não é apenas a concepção de filosofia que está submetida a uma profunda transformação, mas se verifica também uma incidência dessa transformação em algumas das disciplinas filosóficas básicas, tais como a metafísica, a ética, a antropologia e, evidentemente, a filosofia da natureza. /// The present article aims, first of all, to demonstrate the diverse paths by which contemporary society has progressively discovered the ecological problem. In a second moment, it will analyze the historical and cultural roots of the reduction of nature to an object to be exploited by humankind, along with the different ways by which the latter is related to the former. The consequences of the environment due to the uncontrolled use of technology in the transformation of nature will be underscored. Finally, the author considers how philosophy, pressed by the ecological crisis, is in the process of developing a new hermeneutical paradigm: not only is the conception of philosophy itself transformed but the transforming effect is spreading to other areas of philosophical investigation, e.g., metaphysics, ethics, anthropology, and- of course - the philosophy of nature.

This article attempts to analyze the deconstruction of the linear organization of legal systems into a plurality of organized networks conform a circular systemic organization. As we know, the process of systematization runs parallel to the evolution of the modern State and, in this sense, the structure constitutes a single and well defined corps. However, at present, the emergence of multiple legal networks has been seen to turn Law into a structure that translates into a plethora of information that is (...) hard to nuance. Finally, with respect to the emergence of reflexive law, such reflexivity is feasible only when the processes of democratization create discursive structures in social subsystems, so the main problem is to deal with is their identity within a dynamic process of inter-legalities.

Data are lacking with regard to participants' perspectives on return of genetic research results to relatives, including after the participant's death. This paper reports descriptive results from 3,630 survey respondents: 464 participants in a pancreatic cancer biobank, 1,439 family registry participants, and 1,727 healthy individuals. Our findings indicate that most participants would feel obligated to share their results with blood relatives while alive and would want results to be shared with relatives after their death.

For the purpose of reflecting on the pertinence of philosophy in confronting the challenges of our times, we develop the Arendtian concept of thought as a decisive activity in elucidating the moral character of our actions and in our search for sense which eventually becomes judgment, when we consider the faculties that philosophy inherently contain in relation to human affairs This paper presents intercultural philosophy as an example of how philosophy works in times of crisis.

Genomic research results and incidental findings with health implications for a research participant are of potential interest not only to the participant, but also to the participant's family. Yet investigators lack guidance on return of results to relatives, including after the participant's death. In this paper, a national working group offers consensus analysis and recommendations, including an ethical framework to guide investigators in managing this challenging issue, before and after the participant's death.

Education, Religion and Society celebrates the career of Professor John Hull of the University of Birmingham, UK, the internationally renowned religious educationist who has also achieved worldwide fame for his brilliant writings on his experience, mid-career, of total blindness. In his outstanding career he has been a leading figure in the transformation of religious education in English and Welsh state schools from Christian instruction to multi-faith religious education and was the co-founder of the International Seminar on Religious Education and values. (...) John Hull has also made major contributions to the theology of disability and the theological critique of the "money culture." This volume brings together leading international scholars to honour John Hull's contribution, with a focus on furthering scholarship in the areas where he has been active as a thinker. The book offers a critical appreciation of his contribution to religious education and practical theology, and goes on to explore the continuing debate about the role of religious education in promoting international understanding, intercultural education and human rights education. A possible basis for integrating Islamic education into Western education is suggested and the contribution of the philosophy of religion to pluralistic religious education is outlined. The contributors also deal with issues relating to indoctrination, racism and relationship in Christian religious aspects, and examines aspects of the the theology of social exclusion and disability.

We revise the mathematical implementation of the Dirac formulation of quantum mechanics, presenting a rigorous framework that unifies most of versions of this implementation.

Here we defend the view that one ought to categorize and classify at least some mental disorders as clusters of interrelated dysfunctions of (usually, several) cognitive capacities – that is, the kinds of capacities that are postulated in cognitive science; capacities that are understood as entities that are primarily individuated in cognitive-functional terms (CF-systems); systems that have a set of peculiar properties in their manner of operation when processing information or representations. Usually, some of the mental disorders postulated in psychiatry (...) are clinically heterogeneous with respect to their symptoms, and tend to be comorbid – that is, one disorder is often accompanied by other disorders – for example, schizophrenia often comes with major depression. We argue that describing the manner in which CF-systems operate within themselves and with other CF-systems as well as with stimuli and other kinds of information can best explain why certain mental disorders are very heterogeneous with respect to their symptoms, and why comorbidity is so frequent among these disorders. A consequence is that both within-category heterogeneity and comorbodity are not necessarily indications of defective classifications but are rather a consequence of the actual cognitive functional architecture itself and are therefore to be expected in these cases.

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)
