Deriving polarity effects

چکیده
Polarity Items are linguistic expressions known for being a ‘lexically controlled’ phenomenon. In this paper we show how their behavior can be implemented in a deductive system. Furthermore, we point out some possible directions to recast the deductive solution into a Tree Adjoining Grammar system. In particular, we suggest to compare the proof system developed for Multimodal Categorial Grammar (Moot & Puite, 1999) with the Partial Proof Trees proposed in (Joshi & Kulick, 1997).

Deriving Polarity Effects in Inflectional Morphology
In this paper, I argue for a new, theory-neutral approach to polarity effects resting upon the idea that the choice of marker for a given feature specification is determined by the choice of marker for a minimally different specification. In paradigms instantiating polarity effects, the matching of morpho-syntactic and phonological features proceeds by natural class based-rules, but is partly o...
متن کاملA Mechanism Underlying the Electrical Polarity Detection of Sensitive Plant, Mimosa Pudica
Natural indicators of the electrical polarity of a direct current (DC) source is limited to semiconductor based diodes and transistors. Recently a novel bio-natural indicator of the polarity of a DC source have been reported. Mimosa Pudica or sensitive plant is found to be a natural detector of a DC source polarity, however the mechanism underlying this phenomenon is not known. This paper aims ...
متن کاملHow do Negation and Modality Impact on Opinions?
In this paper, we propose to study the effects of negation and modality on opinion expressions. Based on linguistic experiments informed by native speakers, we distill these effects according to the type of modality and negation. We show that each type has a specific effect on the opinion expression in its scope: both on the polarity and the strength for negation, and on the strength and/or the...
متن کاملEffects of solvents polarity parameters on heterogeneous catalytic hydrogenation of cyclohexene in molecular solvents
Heterogeneous catalytic hydrogenation of cyclohexene, catalyzed by Pt/A1203, was carried out in thirteenvarious solvents (four alcoholic solvents, six aprotic polar solvents and three non polar solvents) at 25 °C.Single-parameter correlations of logk vs. normalized polarity parameter (ETN), hydrogen-bond acceptorbasicity (p), hydrogen-bond donor acidity (a) and dipolarity/polarizibility (it*) d...
متن کاملThe Polarity-Dependent Effects of the Bilateral Brain Stimulation on Working Memory
Introduction: Working memory plays a critical role in cognitive processes which are central to our daily life. Neuroimaging studies have shown that one of the most important areas corresponding to the working memory is the dorsolateral prefrontal cortex (DLFPC). This study was aimed to assess whether bilateral modulation of the DLPFC using a noninvasive brain stimulation, namely transcranial di...
