Logic programming rules are provided to capture the rules governing formal poetry in Spanish. The resulting logic program scans verses in Spanish to provide their metric analysis. The program uses DCG grammars to model the division of each word into syllables, and additional predicates are employed to de ne metric phenomena such as synaloepha, syllable count of a verse, rhyme of a word... The s...

An agent communication protocol specifies the "rules of encounter" governing a dialogue between agents in a multiagent system. In non-cooperative interactions (such as negotiation dialogues) occur­ ring in open societies it is crucial that agents are equipped with proper means to check, and possi­ bly enforce, conformance to protocols. We identify different levels of conformance (weak, exhausti...

This paper deals with the derivational morphology of automatic word form recognition. It presents a set of declarative rules which augment lexical entries with information governing the allomorphic changes of derivation in addition to the existing allomorphy rules for inflection. The resulting component generates a single lexicon for derivational and inflectional allomorphy from an elementary b...

Large complexes of classical particles play central roles in biology, in polymer physics, and in other disciplines. However, physics currently lacks mathematical methods for describing such complexes in terms of component particles, interaction energies, and assembly rules. Here we describe a Fock space structure that addresses this need, as well as diagrammatic methods that facilitate the use ...

Inductive reasoning is a fundamental and complex aspect of human intelligence. In particular, how do subjects, given a set of particular examples, generate general descriptions of the rules governing that set? We present a biologically plausible method for accomplishing this task and implement it in a spiking neuron model. We demonstrate the success of this model by applying it to the problem d...

My research fields are development economics and political economy. One strand of my research focuses on the role of property rights institutions — the laws, rules and norms that govern how property is allocated, how property can be transferred, and how property is secured. The second strand focuses on political institutions: the constraints and rules governing policy makers, and the representa...

In this paper, the ethical and legal issues raised by the deactivation of implantable cardioverter-defibrillators (ICDs) in patients with terminal cancer is considered. It is argued that the ICD cannot be well described either as a treatment or as a nontreatment option, and thus raises complex questions regarding how rules governing deactivation should be framed. A new category called ‘‘integra...

This paper presents a fuzzy system approach to the prediction of nonlinear time series and dynamical systems based on a fuzzy model that includes its derivative information. The underlying mechanism governing the time series, expressed as a set of IF–THEN rules, is discovered by a modified structure of fuzzy system in order to capture the temporal series and its temporal derivative information....

Individual’s desires to expand wealth in the face of scarcity underlie the evolution of rules and institutions of governance, as individuals attempt to reduce the transactions costs that impede coordination and motivation in an uncertain world. Some wealth-seeking individuals have or develop comparative advantages in violence, however, and behavioral rules and governing institutions may evolve ...
