This article identifies the two currents that have divided the Left over the Zimbabwe question. It argues that in the course of the radicalisation of the Zimbabwean state, 'Two Lefts' emerged, the so-called 'internationalist' and the 'nationalist', to take up opposite positions over a series of political questions, most notably the agrarian question and the national question. The article defends the nationalist Left and offers a critique of the 'internationalist' Left through a discussion of contemporary imperialism, the neocolonial state, and (...) civil society.

Equational reasoning arises in many areas of mathematics and computer science. It is a cornerstone of algebraic reasoning and results essential in tasks of specification and verification in functional programming, where a program is mainly a set of equations. The usual manipulation of identities while conducting informal proofs obviates many intermediate steps that are neccesary while developing them using a formal system, such as the equationally complete Birkhoff calculus ${\mathcal{B}}$. This deductive system does not fit in the common manner of (...) doing mathematical proofs, and it is not compatible with the mechanisms of proof assistants. The aim of this work is to provide a deductive system ${\mathcal{B}}^{\textrm{GOAL}}$ for equality, equivalent to ${\mathcal{B}}$ but suitable for constructing equational proofs in a backward fashion. This feature makes it adequate for interactive proof-search in the approach of proof assistants. This will be achieved by turning ${\mathcal{B}}^{\textrm{GOAL}}$ into a transition system of formal tactics in the style of Edinburgh LCF, such transformation allows us to give a direct formal definition of backward proof in equational logic.

This study is based on the Acts of Peter, an apocryphal writing of the New Testament. The book, which is actually a work “pious”, popular and exemplary, recounts numerous episodes of magic. Of special interest to maintain the pulse Simon Peter vs Simon Magus, doing magic and miracles in Rome. The ideological background of the book is is an attack against the figure of the bad Roman emperors, whose model is Nerone, character ridiculed as murderer and persecutor of Christians.

This paper reflects on the notion and structural components of two concepts: the human condition and human nature. Likewise, it is proposed that both concepts should be included in the basic themes not only in the field of Educational Philosophy, but also in all disciplines where the human being occupies a privileged place. Human condition is understood as a state of subjection to everything with which human beings interact and represents the starting point to ascend to three natures that correspond (...) to human beings. Hegel emphasizes two natures of man. The first is characterized by having a biological structure governed by instincts. The second is culture and to ascend to it requires processes of intellection that can be objectified through consciousness. The third human nature proposed in this paper is rooted in Ernst Bloch’s principle of hope. It is materialized by human actions tending to the construction of the future from the discovery of what is not-yet-conscious that, when identified, is achieved through actions. (shrink)

Análisis del poema, Últimos días de una casa, de la escritora Dulce María Loynaz. Desde una perspectiva de lo descriptivo y lingüístico que permita al lector acercarse a una de las más sobresalientes poetisas del siglo XX, ganadora del Premio Nobel de Literatura.

Within a formal epistemic model for simultaneous-move games, we present the following conditions: belief in the opponents’ rationality, stating that a player believes that every opponent chooses an optimal strategy, self-referential beliefs, stating that a player believes that his opponents hold correct beliefs about his own beliefs, projective beliefs, stating that i believes that j’s belief about k’s choice is the same as i’s belief about k’s choice, and conditionally independent beliefs, stating that a player believes that opponents’ types choose (...) their strategies independently. We show that, if a player satisfies BOR, SRB and CIB, and believes that every opponent satisfies BOR, SRB, PB and CIB, then he will choose a Nash strategy. We thus provide a sufficient collection of one-person conditions for Nash strategy choice. We also show that none of these seven conditions can be dropped. (shrink)

In this paper we explore the absentminded driver problem using two different scenarios. In the first scenario we assume that the driver is capable of reasoning about his degree of absentmindedness before he hits the highway. This leads to a Savage-style model where the states are mutually exclusive and the act-state independence is in place. In the second we employ centred possibilities, by modelling the states (i.e. the events about which the driver is uncertain) as the possible final destinations indexed (...) by a time period. The optimal probability we find for continuing at an exit is different from almost all papers in the literature. In this scenario, act-state independence is still violated, but states are mutually exclusive and the driver arrives at his optimal choice probability via Bayesian updating. We show that our solution is the only one guaranteeing immunity from sure loss via a Dutch strategy, and that – despite initial appearances – it is time consistent. This raises important implications for the rationality of commitment in such scenarios. (shrink)

In the literature there are at least two models for probabilistic belief revision: Bayesian updating and imaging [Lewis, D. K. (1973), Counterfactuals, Blackwell, Oxford; Gärdenfors, P. (1988), Knowledge in flux: modeling the dynamics of epistemic states, MIT Press, Cambridge, MA]. In this paper we focus on imaging rules that can be described by the following procedure: (1) Identify every state with some real valued vector of characteristics, and accordingly identify every probabilistic belief with an expected vector of characteristics; (2) For (...) every initial belief and every piece of information, choose the revised belief which is compatible with this information and for which the expected vector of characteristics has minimal Euclidean distance to the expected vector of characteristics of the initial belief. This class of rules thus satisfies an intuitive notion of minimal belief revision. The main result in this paper is to provide an axiomatic characterization of this class of imaging rules. (shrink)

Reichle et al. argue that the mechanism that determines where to fixate the eyes is controlled mostly by low-level processes. Therefore, unlike other competing models (e.g., the SWIFT model), the E-Z Reader model cannot account for “global” regressions as a result of linguistic difficulties. We argue that the model needs to be extended to account for regressive saccades.

L’évolution industrielle nous destine à vivre dans des environnements technologiques caractérisés par une dissémination informatique totale dans la multitude et d’objets connectés capables de traitement sémantique et d’interaction informationnelle avec les humains. Dans ce contexte d’Intelligence ambiante se déploient des dispositifs domotiques d’Interactions dites naturelles Homme / machine. Ainsi de Google Home présenté comme : « une enceinte à commande vocale qui fonctionne avec l'Assistant Google ». On pourra tout aussi bien discuter avec les agents de la concurrence : Amazon (...) Echo, Apple HomePod, etc. Ces dispositifs nous conduisent à interroger une étape contemporaine majeure de « la révolution technologique du langage » et de son automatisation, qui fait des machines de réels sujets parlants, inscrits dans un « couplage humano-machinique ». Dans ce contexte fortement marqué par les affordances, nous observons les modalités de cette interaction artéfactuelle et dite naturelle, caractérisée notamment par une simulation conversationnelle et une personnalisation des dispositifs technologiques. La perspective est celle d’une linguistique post-dualiste et non logocentrée, dans la lignée du courant de l’analyse du discours : Texte-Discours-Interaction. (shrink)

Despite the tight link between the visibility of the iris and pupil, the perceived effects of these two have been studied largely in isolation. We demonstrate, across two experimental studies, that the effects of perceived pupil size are dependent on the visibility of the iris. In a first study, our participants donated more and had more positive impressions of portraits of non-human primates when these were manipulated to appear having larger pupils. Post-hoc inspection of our data suggested that the difference (...) was greater for species with more conspicuous irises. In a second study, we concomitantly manipulated iris brightness and pupil size. Brighter irises and larger pupils elicited greater donations. Participants rated photographs with brighter irises as cuter, more attractive and friendlier, but only when they had dilated pupils. Our results have methodological implications for studies manipulating eye appearance, and help interpret results from previous studies. (shrink)

We qualify Frost's proposals regarding letter-position coding in visual word recognition and the universal model of reading. First, we show that perceptual uncertainty regarding letter position is not tied to European languages – instead it is a general property of the cognitive system. Second, we argue that a universal model of reading should incorporate a developmental view of the reading process.

In this paper, we analyze some of the policies implemented by Mexico, a country that has not pursued a total lockdown, although it has implemented different partial confinement policies. Such approach to the confinement has been criticized by some authors as morally inappropriate. Our focus is to show that cultural, political and economic conditions shape the governmental response to the pandemic. While these can be judged on the basis of their efficiency, it seems to us that underlying principles are also (...) ethically acceptable. (shrink)

Este estudio está basado en los Hechos de Pedro, un escrito apócrifo del Nuevo Testamento. El libro, que es en realidad una obra piadosa, popular y ejemplarizante, narra numerosos episodios de magia. Resulta de especial interés el pulso que mantienen Simón Pedro y Simón Mago, realizando prodigios y milagros sin fin en Roma. El trasfondo ideológico del escrito es un alegato contra la figura de los malos emperadores romanos, cuyo modelo es Nerón, personaje ridiculizado y tachado de asesino y perseguidor (...) de los cristianos.
