QCD sum rules vs . chiral perturbation theory

QCD sum rules are useful tools for studying the spectral properties of hadrons; however, assumptions underlying standard sum-rule analyses can lead to inconsistencies with known results of chiral perturbation theory. This possibility is demonstrated with QCD sum-rule extractions of the nucleon mass and σ term. In both cases, inconsistent chiral behavior leads to an uncertainty in the sum-rule p...

Rules vs. Analogy in Mandarin Classifier Selection

A long-running debate concerns whether human language is processed solely by analogy to memorized exemplars, as connectionists have claimed, or instead may be processed by symbolmanipulating rules (e.g. Pinker 1999). In this paper we bring this debate to the Mandarin noun classifier system, arguing that the so-called general classifier 個 ge is selected by a default rule. Reviewing evidence from...

Rules vs . Constraints : A Case Study

In this paper, I sketch a cross-theoretical comparison of the treatment of floating high tones in Mixteco (a language of Southern Mexico studied by Kenneth Pike in the 1930's and 40's).1 My goal is to make a case for a theory of phonology based on violable universal constraints (specifically, Optimality Theory),2 as opposed to the more traditional derivational framework relying on languagespeci...

Instrument-Based vs. Target-Based Rules

We develop a simple delegation model to study rules based on instruments vs. targets. A principal faces a better informed but biased agent and relies on joint punishments as incentives. Instrument-based rules condition incentives on the agent’s observable action; target-based rules condition incentives on outcomes that depend on the agent’s action and private information. In each class, an opti...
