We construct the inverse partition semigroup IPX , isomorphic to the dual symmetric inverse monoid I∗ X , introduced in [6]. We give a convenient geometric illustration for elements of IPX . We describe all maximal subsemigroups of IPX and find a generating set for IPX when X is finite. We prove that all the automorphisms of IPX are inner. We show how to embed the symmetric inverse semigroup in...

In this paper we propose an argumentative account for a discourse constraint on the reinforcement of some implicatures. We argue that this constraint is not due to the nature of inferences at hand but rather on distinct argumentative relations between the propositions they express. We examine the effect of these relations on the possible discourse relations a speaker is entitled to use in his d...

Algebraic properties of logical relations on partially ordered sets are studied. It is shown how to construct a logical relation that extends a collection of base Galois connections to a Galois connection of arbitrary higher-order type. “Theorems-for-free” is used to show that the construction ensures safe abstract interpretation of parametrically polymorphic functions. The properties are used ...

BACKGROUND AND OBJECTIVE Increased demand for non-invasive cosmetic laser procedures has led to an increase in the use of physician extenders (PE). This demand has now led to a variety of medical legal concerns surrounding the use of lasers by non-physician PE. STUDY DESIGN This review looks at the evolution of the relationship between physicians and the various types of PE. The focus of the ...

I have been asked to respond to the comments of three of the most important Brazilian critical thinkers with regard to my short essay about cyber determination. In the first place, I am deeply thankful to the journal Revista Brasileira de Epidemiologia for providing its valuable platform to publish this enriching dialogue raised by the commentaries. Secondly, I must also thank my commentators f...

Deeply Virtual Compton Scattering and electroproduction of mesons involve amplitudes that are analytic in energy. Analyticity enables Dispersion Relations (DR’s) for such amplitudes, relating real and imaginary parts. Lately it has been suggested that DR’s be applied to the integrated Generalized Parton Distributions that embody the spin-dependent soft, but factorizable part of the scattering. ...

most from the beginning, the field has been divided on this question. From a behavioristic viewpoint, the self-concept has an aura of mysticism about it, appearing not far removed from the concept of a soul. One can neither see a self-concept, nor touch it, and no one has succeeded as yet in adequately defining it as a hypothetical construct. Definitions that are offered tend to lack meaningful...

The existing body of knowledge has generally supported that organizational culture plays a significant role in shaping group identity, work pattern, communication schemes, and interpersonal relations; all of these cultural elements are important organizational factors that shape workplaces and operational routines. In the context of emerging information technology, it has also been suggested th...

Symbolic Values, Value Formation and Interpersonal Relations Interpersonal relations are shaped by the judgements associated with the social categories that individuals perceive in their social contacts. I develop a model of how those judgments form based on a theory of symbolic values. The model depicts the interaction between two values, one associated with an inherited ethnic trait (“nationa...

We present our recent work on query-focused summarization, focusing on our efforts in building and applying models of rhetorical-semantic relations (RSRs) such as contrast and causality. We overview ongoing work in extracting and evaluating RSR models. We describe our system for query-focused summarization, focusing on an enhanced, feature-based framework. We present results of experiments to m...
