The method of isonymy to estimate inbreeding is applied to the historical population of the Quebrada de Humahuaca . Data from the baptismal records of the Parochial Church of Humahuaca from 1734 to 1810 were grouped into two periods, 1734–72 and 1773–1810. The analysis was carried out twice: using the surnames exactly as they were registered; combining homonymous surnames which were pronounced or spelt in a similar way. The random and non-random components of inbreeding have been investigated through different methods. (...) There were no significant differences between the results of the two analyses, nor between the expected and observed isonymy. The value of Flies somewhere between those for offspring of first cousins once removed and second cousins once removed. There is a tendency for F and its components to increase through time. It is concluded that the high altitude aboriginal population of Humahuaca Parish must have behaved as a panmictic unit. (shrink)

This paper deals with causal analysis in the social sciences. We first present a conceptual framework according to which causal analysis is based on a rationale of variation and invariance, and not only on regularity. We then develop a formal framework for causal analysis by means of structural modelling. Within this framework we approach causality in terms of exogeneity in a structural conditional model based which is based on (i) congruence with background knowledge, (ii) invariance under a large variety of (...) environmental changes, and (iii) model fit. We also tackle the issue of confounding and show how latent confounders can play havoc with exogeneity. This framework avoids making untestable metaphysical claims about causal relations and yet remains useful for cognitive and action-oriented goals. (shrink)

Causal analysis in the social sciences takes advantage of a variety of methods and of a multi-fold source of information and evidence. This pluralistic methodology and source of information raises the question of whether we should accordingly have a pluralistic metaphysics and epistemology. This paper focuses on epistemology and argues that a pluralistic methodology and evidence don’t entail a pluralistic epistemology. It will be shown that causal models employ a single rationale of testing, based on the notion of variation. Further, (...) I shall argue that this monistic epistemology is also involved in alternative philosophical theories of causation. (shrink)

This article undertakes a deconstructive reading of astrobiology’s search for extraterrestrial life. Taking its lead from Derrida’s ‘White Mythology’, it explores ‘metaphor in the text of astrobiology’—and includes within the astrobiological ‘text’ not only scientific publications and work on astrobiology in the philosophy of science, but also ‘life detection technologies’. I situate astrobiology in the tradition of a metaphysical analogy that goes back through the enlightenment and early modern astronomy to the ancient Atomists’ notion of the ‘plurality of worlds’. This (...) analogy, which constitutes an identification of life with being and therefore serves as the conceptual basis for the notion that life must exist on other worlds, experiences a mutation in the middle of the twentieth century when molecular biology refigures life in terms of a scriptural metaphor as text. The result is an aporia whose logic Derrida formalised in ‘White Mythology’. (shrink)

In 1964, the young Walter Kasper (born in 1933) was granted by the Faculty of Catholic Theology at Tübingen the licence to teach dogmatic theology on the basis of a thesis on Philosophie und Theologie der Geschichte in der Spätphilosophie Schellings (Philosophy and Theology of History in Schelling’s Late Philosophy). Kasper’s interest in Schelling, himself a student at the Evangelisches Stift at Tübingen, thus originated in the context of his university studies in the school of J.R. Geiselmann and developed in (...) parallel with his theological education. For this reason, it is impossible to form a correct idea of Kasper and his whole theology unless one is willing to take into account this background, not least because he himself has always consciously and forcefully recognised this fact and seen in it his own centre of gravity. Kasper’s work and thought were shaped in a lasting manner during his university years. In fact, his entire academic oeuvre has been nurtured from this fecund origin so much so that he became one of the most well known names associated with the Catholic school at Tübingen to which he gave a new, creative impulse having himself been profoundly inspired by it. ‘He always emphasised his own roots not only as a teacher of theology and a member of the teaching faculty of this institution, but also as bishop’ and cardinal. The principal intention of the present article is precisely this: to return to this beginning and elucidate these decisive years for Kasper in broad outline by way of a relecture and interpretation of his book on The Absolute in History and the particular manner in which he interpreted the so-called second Schelling, an author whom he approached in the wake of Walter Schulz and at practically the same time as Xavier Tilliette. The analysis will subsequently move on into the more properly theological field. (shrink)

This article aims to highlight the theoretical and philosophical debate on hospitality underlining the normative elements of framing migrants and refugees as individual agents in the light of hospitality theory and migration governance. It argued the critiques of the neo-Kantian hospitality approach and the EU welcome culture with regard to refugees in the EU from a philosophical perspective. The “No human being is illegal” motto is proposed to be conceived as a principle of the EU Charter of Fundamental Rights. The (...) cosmopolitan right to visit and the universal right to reside were discussed in the context of human rights and co-responsibility. Linking the hospitality approach with migration governance enables the reconstruction of reception policies and practices, diversification of non-state actors that engage in migration governance mechanism, and polarization of political initiatives (e.g., politics of allocation and dispersal, readmission negotiations, convergence/divergence of priorities and strategic interests). The research findings highlight that the EU adopted a neo-Kantian hospitality approach that combines both “co-responsibility” and “vertical/heterarchical relations.” The EU’s “New Pact on Migration and Asylum” was considered proof of how the EU follows neo-Kantian hospitality that is manifested in dualism and contradictory approach. The study presents a typology that splits co-responsibility into individual/institutional actions and human rights/migration governance. (shrink)

Phillips & Silverstein (P&S, 2003) propose that NMDA-receptor dysfunction may be the fundamental neurobiological mechanism underlying and associating impaired holistic perception and cognitive coordination with schizophrenic psychopathology. We discuss how the P&S hypothesis shares different aspects of the weak central coherence account of autism from both theoretical and experimental perspectives. Specifically, we believe that neither those persons with autism nor those with schizophrenia integrate visuo-perceptual information efficiently, resulting in incongruous internal representations of their external world. However, although NMDA-hypofunction may be (...) responsible for perceptual impairments in schizophrenia and possibly autism, we suggest that it is highly unlikely that NMDA-hypofunction is specifically responsible for the autistic behavioral symptomology, as described by P&S in their target article.

We propose communication pattern logic. A communication pattern describes how processes or agents inform each other, independently of the information content. The full-information protocol in distributed computing is the special case wherein all agents inform each other. We study this protocol in distributed computing models where communication might fail: an agent is certain about the messages it receives, but it may be uncertain about the messages other agents have received. In a dynamic epistemic logic with distributed knowledge and with modalities (...) for communication patterns, the latter are interpreted by updating Kripke models. We propose an axiomatization of communication pattern logic, and we show that collective bisimilarity (comparing models on their distributed knowledge) is preserved when updating models with communication patterns. We can also interpret communication patterns by updating simplicial complexes, a well-known topological framework for distributed computing. We show that the different semantics correspond, and propose collective bisimulation between simplicial complexes. (shrink)

In this essay, a brief analysis of the diplomatic efforts to achieve an accord in re- lation to the climatic change process is made. Particularly, it will analyze the two past Climate Summits (Copenhagen and Cancun). It emphasizes the growing social articulation of climatic politics. Finally, it aims to the birth of a new global responsibility of societies in relation to the human relation towards the planet. Also, it explores the impact of this responsibility on the environment global changes.

The complete description of the interaction between an external electromagnetic field and a charged particle causing it to radiate is one of the most fundamental problems in classical electrodynamics. Here we provide a simple coupled model that describes via the Lagrangian of the physical system the full radiation reaction process resulting from the particle–field interactions which simulate the electromagnetic ones. The particle and field evolution equations obtained from the Lagrangian are studied as an initial value problem giving rise to the (...) particle's radiation reaction equation, which includes the complete interaction with the field. Using stability theory we analyze this equation and prove that every solution is global uniform asymptotically stable, evidencing that the particle coupled to the field radiates. The model proves to be interesting, for it clearly illustrates the particle–field interaction process and shows the radiation's origin. (shrink)

Most model checking techniques for security protocols make a number of simplifying assumptions on the protocol and/or on its execution environment that greatly complicate or even prevent their applicability in some important cases. For instance, most techniques assume that communication between honest principals is controlled by a Dolev-Yao intruder, i.e. a malicious agent capable to overhear, divert, and fake messages. Yet we might be interested in establishing the security of a protocol that relies on a less unsecure channel (e.g. a (...) confidential channel provided by some other protocol sitting lower in the protocol stack). In this paper we propose a general model for security protocols based on the set-rewriting formalism that, coupled with the use of LTL, allows for the specification of assumptions on principals and communication channels as well as of complex security properties that are normally not handled by state-of-the-art security protocol analysers. By using our approach we have been able to formalise all the assumptions required by the ASW protocol for optimistic fair exchange and some of its key security properties. Besides the previously reported attacks on the protocol, we report a new attack on a patched version of the protocol. (shrink)

The Venezuelan-Chilean humanist Andrés Bello has been recognized as one of the most distinguished intellectuals of the 19th century—one of the last polymaths of the stature of figures such as Athanasius Kircher, Gottfried Leibniz or Benjamin Franklin. Indeed, his numerous contributions span fields such as grammar, poetry, civil law, diplomacy, education, political theory, philology and philosophy. However, despite having composed one of the most important philosophical treatises ever written in Spanish, his philosophical proposals have not been engaged with a substantial (...) way by scholars of the Anglophone world.

En las últimas décadas un sector de la Iglesia católica latinoamericana ha impulsado la idea de conformar una Iglesia con rostro indígena, en la cual los indígenas se incorporen a la estructura eclesiástica a través de algunos cargos como catequista o diácono. Algunos incluso han propuesto la ordenación de sacerdotes indígenas que, de acuerdo a la cosmovisión de los indígenas, deben ser casados. El presente artículo tiene el objetivo revisar, desde la perspectiva de la historización de los conceptos propuesta por (...) Ellacuría, el aporte teóricopráctico realizados por la Compañía de Jesús, en particular tres religiosos ignacianos —Xavier Albó, Manuel Marzal y Bartomeu Melià— a dicho proceso. Como se verá a lo largo del texto, ha sido un camino lleno de avances y retrocesos. En el ámbito teórico, los jesuitas han defendido la idea de que la inculturación es el mejor camino para que la Iglesia logre una verdadera inserción en la realidad de las comunidades indígenas. En el terreno práctico se explora la experiencia de los diáconos indígenas en dos regiones: en la zona aymara de los Andes —especialmente en Bolivia— y en la Misión de Bachajón, Chiapas. Ambas experiencias con resultados disimiles, pero que enriquecen el caminar de la Iglesia con rostro indígena. (shrink)
