The aim of this study consists of postulating an ethical approach to Human Rights conceiving them as rights of the other, claiming that this approach represent a starting point for the development of a legal pluralism that contributes to the achievement of an effective and authentic peace. For this study is based on the premise that the law must be able to deal with the serious and still pending social and environmental problems that underlie the violations of human rights, especially (...) those of ecological nature. By way of conclusion, the need for a radical change of the paradigm is evidenced, for which a perspective of ethics as a linguistic praxis is proposed, since such praxis has the potential to inspire the reformulation of human rights, for the purpose of reversing the dynamics of violence imposed by the logic of identity underlying the current legal system.

We consider small-weight Cutting Planes (CP * ) proofs; that is, Cutting Planes (CP) proofs with coefficients up to $\operatorname{Poly}(n)$ . We use the well known lower bounds for monotone complexity to prove an exponential lower bound for the length of CP * proofs, for a family of tautologies based on the clique function. Because Resolution is a special case of small-weight CP, our method also gives a new and simpler exponential lower bound for Resolution. We also prove the following (...) two theorems: (1) Tree-like CP * proofs cannot polynomially simulate non-tree-like CP * proofs. (2) Tree-like (CP * proofs and Bounded-depth-Frege proofs cannot polynomially simulate each other. Our proofs also work for some generalizations of the CP * proof system. In particular, they work for CP * with a deduction rule, and also for any proof system that allows any formula with small communication complexity, and any set of sound rules of inference. (shrink)

We introduce new proof systems for propositional logic, simple deduction Frege systems, general deduction Frege systems, and nested deduction Frege systems, which augment Frege systems with variants of the deduction rule. We give upper bounds on the lengths of proofs in Frege proof systems compared to lengths in these new systems. As applications we give near-linear simulations of the propositional Gentzen sequent calculus and the natural deduction calculus by Frege proofs. The length of a proof is the number of lines (...) in the proof. A general deduction Frege proof system provides at most quadratic speedup over Frege proof systems. A nested deduction Frege proof system provides at most a nearly linear speedup over Frege system where by "nearly linear" is meant the ratio of proof lengths is O) where α is the inverse Ackermann function. A nested deduction Frege system can linearly simulate the propositional sequent calculus, the tree-like general deduction Frege calculus, and the natural deduction calculus. Hence a Frege proof system can simulate all those proof systems with proof lengths bounded by O). Also we show that a Frege proof of n lines can be transformed into a tree-like Frege proof of O lines and of height O. As a corollary of this fact we can prove that natural deduction and sequent calculus tree-like systems simulate Frege systems with proof lengths bounded by O. (shrink)

We extend results of Bonet, Buss and Pitassi on Bondy’s Theorem and of Nozaki, Arai and Arai on Bollobás’ Theorem by proving that Frankl’s Theorem on the trace of sets has quasipolynomial size Frege proofs. For constant values of the parametert, we prove that Frankl’s Theorem has polynomial size AC0-Frege proofs from instances of the pigeonhole principle.

We consider a modification of the pigeonhole principle, M P H P, introduced by Goerdt in [7]. M P H P is defined over n pigeons and log n holes, and more than one pigeon can go into a hole (according to some rules). Using a technique of Razborov [9] and simplified by Impagliazzo, Pudlák and Sgall [8], we prove that any Polynomial Calculus refutation of a set of polynomials encoding the M P H P, requires degree Ω(log n). We (...) also prove a simple Lemma giving a simulation of Resolution by Polynomial Calculus. Using this lemma, and a Resolution upper bound by Goerdt [7], we obtain that the degree lower bound is tight. Our lower bound establishes the optimality of the tree-like Resolution simulation by the Polynomial Calculus given in [6]. (shrink)

Der Beitrag setzt an der Form und Dynamik von Freuds Text »Jenseits des Lustprinzips« an und zeigt Denkmöglichkeiten auf, die er eröffnet. Eine Skizze zum Lesen und Wiederlesen vorausschickend geht der Beitrag in vier Schritten vor: Zunächst stellt er die Bedeutung des Stummen als Merkmal des Freud’schen Todestriebs ins Zentrum. Zweitens befasst er sich mit dem Konzept der Triebmischung und -entmischung und stellt dar, auf welche Weise es in die spätere Theoriebildung Freuds und anderer Autoren eingeflossen ist. Drittens zieht er (...) anhand einer Re-Lektüre des »Fort-Da«-Spiels eine Verbindungslinie von der Stummheit über die Trieb(ent)mischung hin zur Symbolisierung. In einem abschließenden Schritt werden die verschiedenen Argumentationsstränge zu einer Interpretation des Textes zusammengeführt: Freuds Denken und Schreiben, das die Autorin als »dekonstruierend« versteht, erlaubt nach ihrer Auffassung, Zusammenhänge zwischen psychischer Repräsentanz und Todestrieb zu postulieren und im Todestriebkonzept einen Beitrag zur Frage der Subjektkonstitution zu erkennen.

Dibujar el pensamiento de Seneca es dibujar su figura viva, trazar el esquema de su persona. Seneca es un mediador que para alzarse sobre nosotros necesita de nuestra necesidad, pues solo apoyado en nuestra indigencia tiene sentido. Maria Zambrano lleva a cabo un lucido estudio de la figura y significacion del pensador cordobes y presenta una seleccion de sus escritos.

Tomando como marco de referencia algunos conceptos básicos de la teoría política de Gramsci, el objetivo principal de este artículo es criticar la función hegemónica e ideológica que la democracia representativa desempeña en el contexto social e histórico de la globalización neoliberal. Lejos de avanzar hacia el ideal emancipador que representa, en la época del neoliberalismo globalizado la democracia es un instrumento de dominación al servicio de una regulación social excluyente y desigual que origina nuevas formas de autoritarismo.

Der Beitrag plädiert dafür, psychoanalytische Erfahrung, psychoanalytisches Denken und psychoanalytische Methoden in die interdisziplinäre Forschung zur Digitalisierung einzubringen. Er schlägt insbesondere einen Dialog mit der Medientheorie vor und zeigt Schnittstellen zu dieser auf. In einem kurzen historischen Abriss wird daran erinnert, in welcher Weise psychoanalytische Ansätze seit den Anfängen sozial-, kultur- und medienwissenschaftlicher Untersuchungen zu Computer und Internet involviert waren. Verschiedene psychoanalytische Diskurslinien werden beschrieben und diskutiert; im Zentrum steht die Frage, ob es Grund gibt zu der Annahme, dass sich (...) im kulturellen Prozess der Digitalisierung wesentliche Strukturen der Subjektivierung verändern, bzw. wie man diese Annahme mit psychoanalytischen Mitteln untersuchen kann.

Positive reappraisal strategies have been found to reduce negative affect following the recall of negative personal events. This study examined the restorative effect of two mood-repair instructions (self-compassion vs benefit-focused reappraisal) and a control condition with no instructions following a negative Mood Induction Procedure by using the guided recall of a negative autobiographical event. A total of 112 university students participated in the online study (81% women, Mage: 21.0 years). Immediately following the negative memory recall, participants were randomised to each (...) condition [(self-compassion: n = 36, benefit-focused: n = 39) or a control condition (n = 37)]. Repeated measures ANOVAs 3 (Repair condition) × 3 (Time of mood assessment: pre-recall, post-recall, post-regulation) showed that, as expected, negative mood (sadness, shame, and guilt) worsened significantly after the guided recall in all groups (p <.001). After the mood-repair intervention, participants in the self-compassion and benefit-focused conditions showed a significant reduction in negative mood (p <.019), while such improvement was not observed in the control group. Self-compassion and benefit-focused reappraisal functioned similarly as mood repair strategies after experiencing negative affect induced by the recall of negative personal memories. Implications in the context of autobiographical memory biases are discussed. (shrink)

The “language-communication-society” triangle defies traditional scientific approaches. Rather, it is a phenomenon that calls for an integration of complex, transdisciplinary perspectives, if we are to make any progress in understanding how it works. The highly diverse agents in play are not merely cognitive and/or cultural, but also emotional and behavioural in their specificity. Indeed, the effort may require building a theoretical and methodological body of knowledge that can effectively convey the characteristic properties of phenomena in human terms. New complexity approaches (...) allow us to rethink our limited and mechanistic images of human societies and create more appropriate emo-cognitive dynamic and holistic models. We have to enter into dialogue with the complexity views coming out of other more ‘material’ sciences, but we also need to take steps in the linguistic and psycho-sociological fields towards creating perspectives and concepts better fitted to human characteristics. Our understanding of complexity is different – but not opposed – to the one that is more commonly found in texts written by people working in physics or computer science, for example. The goal of this book is to extend the knowledge of these other more ‘human’ or socially oriented perspectives on complexity, taking account of the language and communication singularities of human agents in society.

This book offers insights on the study of natural language as a complex adaptive system. It discusses a new way to tackle the problem of language modeling, and provides clues on how the close relation between natural language and some biological structures can be very fruitful for science. The book examines the theoretical framework and then applies its main principles to various areas of linguistics. It discusses applications in language contact, language change, diachronic linguistics, and the potential enhancement of classical (...) approaches to historical linguistics by means of new methodologies used in physics, biology, and agent systems theory. It shows how studying language evolution and change using computational simulations enables to integrate social structures in the evolution of language, and how this can give rise to a new way to approach sociolinguistics. Finally, it explores applications for discourse analysis, semantics and cognition. (shrink)
