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...

Mobile work is a form of work organization that is gaining ground and affecting many organizations. Mobility increases distance in interpersonal relations. The distance that it generates has major consequences for organizations and for leadership dynamics. This article presents the results of a study that tested the impact of physical distance and psychological distance on the quality of the su...

A philosopher has argued that there can be no such thing as a provably correct system. Some software reliability and safety experts believe that no system can have a software reliability of 1. These claims are related, and they are both mistaken, which we prove with a simple counterexample. But is this the only kind of counterexample? An interesting question arises: which types of systems admit...

In his seminal paper on “Types, Abstraction and Parametric Polymorphism,” John Reynolds called for homomorphisms to be generalized from functions to relations. He reasoned that such a generalization would allow type-based “abstraction” (representation independence, information hiding, naturality or parametricity) to be captured in a mathematical theory, while accounting for higher-order types. ...

This study evaluates the effect of a nurse training program in family planning counseling skills on the quality of service delivery at the clinic level, as well as its impact on client compliance with prearranged appointments. The study used a quasi-experimental design to compare certified nurses who received six weeks of family planning technical training with certified nurses who, in addition...
