Hesitations are prevalent in spontaneous speech and believed to be relevant to on-line speech planning. We tested the complexity hypothesis that speakers are more likely to need to suspend speaking, the more complex the constituent, by examining ratios of filled pauses (fillers) at clause and case boundaries with following constituents of different degrees of complexity, using ì the Corpus of s...

Male swordtail fish of the genus Xiphophorus develop a sword, a colourful extension of the caudal fin, that evolved by sexual selection through female choice. Swords and gonopodia, an intromittent organ developing from the male anal fin, can be prematurely induced by exogenous testosterone, offering the opportunity to examine the identity and expression profiles of genes required during various...

This paper investigates whether extensions of the Calvo and menu-cost models that include idiosyncratic technology shocks are consistent with key features of individual consumer price adjustment. The comparison of the models focuses on three facts pertaining to the impact of inflation on the setting of consumer prices. First, the average frequency of consumer price changes initially rises slowl...

gladiolus (gladiolus grandiflorus l.), a popular bulbous cut flower, has high demand in both domestic (pakistani) as well as international markets. five potential, exotic cultivars of gladiolus, ‘cantate’, ‘corveira’, ‘eminence’, ‘essential’ and ‘fado’ were evaluated to determine the cultivar effects on yield and quality, to compare their relative performance and recommend their suitability for...

In a convincing analysis of the conditions and strength of altruism, Bester and Güth [Journal of Economic Behavior & Organization, Vol. 34, 1998, 193-209] unfortunately restrict the interpretation of their results. Their paper provides us with an analysis of the conditions and strength of malevolence (or envy) as well. ©2000 Elsevier Science B.V. All rights reserved. JEL classification: A13; C7...

The analyses, opinions and findings of these papers represent the views of the authors, they are not necessarily those of the Banco de Portugal. In this paper we study the implications of the absence of statistical arbitrage opportunities (SAO) in a two-period incomplete market economy where default is allowed but there are collateral requirements. We study the existence of state price deflator...

We study set algebras with an operator (SAO) that satisfies the axioms of S5 knowledge. A necessary and sufficient condition is given for such SAOs that the knowledge operator is defined by a partition of the state space. SAOs are constructed for which the condition fails to hold. We conclude that no logic singles out the partitional SAOs among all SAOs.

Despite the use of conventional physical and chemotherapeutic agents for caries management, dental caries still continues to be the most prevalent oral infectious disease. Thus, there is a need of additional caries prevention approaches. Strain replacement therapy is one such novel approach. In this, relatively avirulent strains of Streptococcus mutans produced by recombinant DNA technology are...
