A survey of algorithms for free unification is given, followed by an overview of the computability and complexity of unification problems. Second-order unification is known to be undecidable, and a proof is given that the first-order problem is also undecidable under an arbitrary set of axioms. A new systolic algorithm is introduced for term minimisation or term compaction. This is a general-purpose tool for systems using structure sharing. Apart from time and space savings, its use allows subterms to be tested for equality in constant time. The use of compact terms greatly simplifies free term matching and gives rise to a linear-time algorithm with lower processing overheads than the Paterson-Wegman unification algorithm. A sublinear-time solution to the same problem is also given, assuming preloaded data. No existing algorithm for free unification has a sublinear-time implementation and this is related to the notion of a sparse P-complete problem. The complexity of restricted associative-commutative term matching is analysed. Contrary to an earlier conjecture the problem is NP-complete if variables occur at most twice but their number is unrestricted. Parallel methods are suggested as efficient solutions for the | tractable | linear and 1-variable versions of the problem. Results presented here should be useful in the implementation of fast symbolic ma- nipulation systems.

This document presents an axiom selection technique for classic first order theorem proving based on the relevance of axioms for the proof of a conjecture. It is based on unifiability of predicates and does not need statistical information like symbol frequency. The scope of the technique is the reduction of the set of axioms and the increase of the amount of provable conjectures in a given time. Since the technique generates a subset of the axiom set, it can be used as a preprocessor for automated theorem proving. This technical report describes the conception, implementation and evaluation of ARDE. The selection method, which is based on a breadth-first graph search by unifiability of predicates, is a weakened form of the connection calculus and uses specialised variants or unifiability to speed up the selection. The implementation of the concept is evaluated with comparison to the results of the world championship of theorem provers of the year 2012 (CASC J6). It is shown that both the theorem prover leanCoP which uses the connection calculus and E which uses equality reasoning, can benefit from the selection approach. Also, the evaluation shows that the concept is applyable for theorem proving problems with thousands of formulae and that the selection is independent from the calculus used by the theorem prover. / Dieser technische Report beschreibt die Konzeption, Implementierung und Evaluation eines Verfahrens zur Auswahl von logischen Formeln bezüglich derer Relevanz für den Beweis einer logischen Formel. Das Verfahren wird ausschließlich für die Prädikatenlogik erster Ordnung angewandt, wenngleich es auch für höherstufige Prädikatenlogiken geeignet ist. Das Verfahren nutzt eine unifikationsbasierte Breitensuche im Graphen wobei jeder Knoten im Graphen ein Prädikat und jede existierende Kante eine Unifizierbarkeitsrelation ist. Ziel des Verfahrens ist die Reduktion einer gegebenen Menge von Formeln auf eine für aktuelle Theorembeweiser handhabbare Größe. Daher ist das Verfahren als Präprozess-Schritt für das automatische Theorembeweisen geeignet. Zur Beschleunigung der Suche wird neben der Standard-Unifikation eine abgeschwächte Unifikation verwendet. Das System wurde während der Weltmeisterschaft der Theorembeweiser im Jahre 2014 (CASC J6) in Manchester zusammen mit dem Theorembeweiser leanCoP eingereicht und konnte leanCoP dabei unterstützen, Probleme zu lösen, die leanCoP alleine nicht handhaben kann. Die Tests mit leanCoP und dem Theorembeweiser E im Nachgang zu der Weltmeisterschaft zeigen, dass das Verfahren unabhängig von dem verwendeten Kalkül ist und bei beiden Theorembeweisern positive Auswirkungen auf die Beweisbarkeit von Problemen mit großen Formelmengen hat.

Many artist-teachers struggle to nurture and pursue their ambitions in their dual roles. The purpose of this research is to explore the nature of the professional practices of artist-teachers. While there is a substantial amount of research that provides models of artist-teachers, who teach at the post secondary levels, there are not many models for artist-teachers who teach primary and secondary age groups. Four artist-teachers, whose practices are currently contributing to the art world, as well as the educational world, were interviewed for a multiple case study. The roles represented in the study include painters, sculptors, a ceramist, a musician, a performance artist, art teachers, a music teacher, and a performance-art educator. This multiple case study provides four models of artist-teachers whose professional practices contribute to their identity and fulfillment in their dual roles. The study reveals the artist-teacher’s practice as an artist, practice as a teacher and relationship between the dual roles.

Essa fuga, segundo ele, consiste em assemelhar-se a deus. Plotino, em sua exegese do texto platônico, retoma literalmente essa afirmação e a incorpora em sua filosofia. Sua interpretação e concepção filosófica desse aspecto ético da tradição platônica parece corresponder a certa “chave” para compreender e penetrar o percurso da conversão (epistrophé) da alma, de sua dispersão na multiplicidade (ou “queda” nos vícios e males) à sua Assimilação e unificação com o princípio que, por ser fonte de máxima unidade, plenitude, conhecimento e felicidade da alma é, por isso, sua verdadeira meta e seu mais profundo “objeto” de amor e desejo. Portanto, é preciso fugir dos males, em um movimento de conversão e Assimilação a deus (homoíosis theôi), que, em Plotino, corresponde a um retorno e a uma entrada no mais profundo e íntimo de si mesmo. Entretanto, seguindo de perto Platão, se os males residem aqui, para fugir dos males é preciso “fugir daqui”. Ora, perguntamo-nos: o que, em Plotino, significa realmente essa Fuga? É bastante conhecida certa interpretação contemporânea que entende a moral platônica como uma forma de fuga e negação do corpo, do mundo e dos sentidos. Alguns filósofos, assim como alguns historiadores da filosofia, também parecem ter entendido literalmente essa expressão retomada por Plotino. Entretanto, a despeito dessa interpretação e do debate com seus defensores, desejamos apenas compreender esse aspecto da filosofia plotiniana principalmente a partir de seu próprio texto: afinal, trata-se de uma proposta de evasão e de negação do corpo e do mundo, ou há outra leitura possível? Se, paralelamente ao tema da Fuga, estudarmos alguns pontos estratégicos para a compreensão mais ampla do percurso conversivo veremos que paradoxalmente Plotino não apenas valoriza o corpo, o mundo e a experiência sensível, mas os concebe como meios para a Assimilação ao inteligível. Por conseguinte, se fugir daqui consiste em assemelhar-se a deus, essa Assimilação é a finalidade última dessa Fuga. De modo que Fuga e Assimilação aparecem como conceitos interdependentes. Todavia, qual é a natureza dessa Assimilação (homoíosis)? Trata-se apenas de imitar e tornar-se semelhante ao divino, ou esse termo guarda, em Plotino, ainda um sentido mais ousado e mais profundo? Segundo nossa interpretação, a assemelhação como imitação e aproximação ao divino, por meio das virtudes e da dialética, é uma etapa ainda propedêutica da Assimilação propriamente dita. E é essa passagem de um nível discursivo e propedêutico – de imitação e preparação – para a “visão” e a “experiência” imediata do divino – como “unificação”, “contato” e “união extática” e “mística” – que completa o itinerário filosófico da conversão da alma, condensado em sua interpretação desses dois conceitos complementares e convergentes. / In his Theaetetus (176 b), Plato stated that as evils lie “here” and necessarily prowl this perishable region, and as we aspire escaping from these evils, “escaping from here” is a must. According to him, this escape is based upon resembling god-like. Plotinus, upon his exegesis on the platonic text, literally resumes this assertion and incorporates this into his philosophy. His interpretation and philosophical conception of this Platonic tradition ethical feature seem to correspond to a certain "key" to understanding and penetrating the soul conversion route (epistrophé), its dispersion into the multiplicity (or "fall" into the addictions and evils) into the assimilation and unification along with the principle which, for being a source of maximum unity, wholeness, knowledge and happiness of the soul is, therefore, its true goal and innermost "object" of love and desire. Therefore, we must shun evils, in a movement of conversion and assimilation to godhood (homoíosis theôi), which in Plotinus corresponds to a return and an ingress into a deeper and more intimate self. However, closely following Plato, if the evils reside here, to escape from these evils we need to "run away from here". Now we ask ourselves: what in Plotinus does this escape really mean? Well known is certain contemporary interpretation which understands the Platonic moral as a form of escape and abnegation of the body, the world and the senses. Some philosophers, as well as some philosophy historians, seem to have understood literally this expression taken up by Plotinus. Though, in spite of this interpretation and debate with its supporters, we just want to understand this aspect of Plotinian philosophy from its own text: after all, it is a proposal of evasion and abnegation of the body and the world or is there another possible reading of the text? In addition to the theme of the Fugue, if we study some strategic points to acquire a broader comprehension of the conversion course we will behold that paradoxically Plotinus not only values the body, the world and the sense experience, but also conceives them as ways to assimilate the intelligible. Therefore, if escaping from here consists in resembling god, this assimilation is the ultimate purposal of this Fugue. So that Fugue and Assimilation come to light as interdependent concepts. However, what is this assimilation nature (homoíosis)? It is just to imitate and become god-like or does that term retain in Plotinus a bolder and deeper sense yet? According to our interpretation, the resemblance as imitation and approximation to the divine through the virtues and dialectics ways is yet a propaedeutical stage of that proper assimilation itself. And it is this passage from a discursive and introductory level – of imitation and preparation – to the "vision" and immediate "experience" of the divine – as "unification", "contact" and "ecstatic and mystical union" – that supplements the soul conversion philosophical itinerary condensed in the interpretation of these two complementary and convergent concepts.

Trata-se de estudo sobre desafios existentes para a harmonização do direito do comércio internacional, entendendo-se harmonização de forma ampla, como busca da harmonia dos instrumentos e regras do comércio internacional. Dessa forma, o estudo trata tanto de questões de unificação quanto de harmonização do direito do comércio internacional. A harmonização, em sentido específico, deve ser entendida como a utilização de um instrumento como modelo ou fonte de inspiração para a elaboração ou interpretação de outros instrumentos ou dos direitos nacionais. A unificação, por sua vez, é entendida como o resultado da aplicação de um instrumento único de modo que o aplicador que a realizou seja indiferente. Nesse sentido, os desafios estão nos fatores que impedem o preenchimento dos requisitos que levam à unificação e à harmonização, quais sejam: elaboração dos instrumentos, entrada em vigor dos tratados, incorporação dos modelos aos direitos nacionais, aplicação dos instrumentos pelos aplicadores (árbitros e juízes), o que inclui questões relativas a regras de conflito de leis, normas imperativas e ordem pública, relação entre os instrumentos quando da sua elaboração e quando da sua aplicação. / This essay concerns challenges on the harmonization of international commercial law. Harmonization shall be understood in a wide fashion, as the efforts to reach harmonic solutions on international commercial law. Harmonization, in a strict fashion, occurs when an instrument is used as a model or source of inspiration for the drafting or the application of another instrument or domestic laws. Unification, in turn, concerns the result accruing from the application of a sole instrument in order to reach results similar enough no matter who applied it. In this sense, challenges as considered for the purpose of this study are factors that somehow bar the fulfillment of the requirements leading to unification or harmonization: drafting of instruments, enforcement of treaties, incorporation of models to domestic law, application of instruments by judges or arbitrators, including issues related to conflict of laws, mandatory rules and public policy, the relation among coexisting instruments both on their drafting and on their application.

O objetivo desta pesquisa é mostrar como a interpretação do conceito Bushidô, pelo pensador e educador Inazo Nitobe, presente na obra Bushido The Soul of Japan, contribuiu para a formação de uma imagem heroicizada dos samurais durante o Período Meiji (1868-1912), e foi utilizada pelos intelectuais da época para fundamentar os valores éticos e morais que todos os cidadãos japoneses deveriam se respaldar, além de ser parte da ideologia nacionalista que se constituía. Bushidô é antigo código de conduta dos samurais japoneses utilizado principalmente no Período Tokugawa (1603-1868) e a utilização do termo por Nitobe, já no Período Meiji, foi condizente com o contexto histórico da época. Veremos que, por meio desta releitura do bushidô tentou-se elaborar um sistema ético moderno a partir de uma tradição inventada, que fornecia um herói nacional (o samurai) reinterpretando costumes nipônicos de modo a associá-los aos conceitos europeus da época, de modo a evidenciar uma evolução social possibilitado necessariamente pela presença e cultivo do caráter moral dos cidadãos. / The objective of this research is to show how the interpretation of the term Bushido, the thinker and educator Inazo Nitobe, present in the work Bushido The Soul of Japan, contributed to the formation of an image heroicized samurai during the Meiji Period (1868-1912), and was used by the intellectuals of the time to support the ethical and moral values that all Japanese citizens should be backed, and is part of the nationalist ideology that was. Bushido code of conduct is ancient Japanese samurai used mainly in the Tokugawa Period (1603-1868) and the use of the term by Nitobe, since the Meiji Period, was consistent with the historical context of the time. We will see that through this remake of Bushido tried to develop a modern system of ethics from an invented tradition, which provided a national hero (samurai) reinterpreting customs Nips to associate them with European concepts of time, so to show a social evolution necessarily made possible by the presence and cultivation of moral character of citizens.

This essay will focus on Henry V, one of William Shakespeare’s historical plays. The protagonist, King Henry V, is a character who holds immense control and prominence in the play and is therefore central to most analyses of it. Previous research has explored how power is portrayed in the play, as well as various aspects of its power structures, such as the relationship between the soldiers and the king as well as the liability for the inevitable death that accompanies battle. Based on this earlier research, this study investigates Henry’s attempted unification of his army as well as the question of responsibility and how these aspects affect the king’s power. It argues that Henry’s dynamic and sometimes ambivalent approach to these aspects help him maintain and further his power, by doubling down on his powerful position while still avoiding any negative repercussions.
