Principlism, a most prominent approach in bioethics, has been criticized for lacking an underlying moral theory. We propose that the four principles of principlism can be related to the four traditional cardinal virtues. These virtues appear prominently in Plato's Republic and in Aristotle's Nicomachean Ethics. We show how this connection can be made. In this way principlism has its own compell...

We present a principled approach to selecting a surface reflectance model and setting its parameters. The approach is based on fundamental physical principles, comparisons between different models, and practical insight into the characteristics of real surfaces. Four models of surface reflectance were evaluated by comparing them with physical measurements on five different sample surfaces. Conc...

for many linguists and scholars, the criterion of eloquence in arabic language is based upon the two elements of language and place and they have ignored internal criteria of words, internal order, kinds of letters, collocations, assonance, dissonance and the power of their impact. the fact is that, linguists and the scholars of eloquence were of different opinions about words. it means that li...

Among the variety of heuristics evaluation methods available, four paramount approaches have emerged: Nielsen's ten usability heuristics (1994), Shneiderman's Eight Golden Rules of Interface Design (1998), Tognazzini's First Principles of Interaction Design (2003), and a set of principles based on Edward Tufte's visual display work (UW Computing & Communications, 1999). To simplify access to a ...

XIS is a R&D project which mission is to analyze, develop and evaluate mechanisms and tools to produce information systems from a more efficient and productive way than it is done currently. XIS project is influenced by MDA reference model, and is mainly based on three principles: it is based on high-level models specification; it is based on generative programming techniques; and it is compone...

This paper takes an overtly anticipatory stance to the understanding of animat learning and behavior. It analyses four major animal learning theories and attempts to identify the anticipatory and predictive elements inherent to them, and to provide a new unifying approach based on the predictive nature of those elements. Parallels are then drawn with Karl Popper’s “Logic of Scientific Discovery...

The paper describes the architectural principles of a database CASE tool that allows more flexible design strategies than those of traditional tools that propose oversimplistic draw-and-generate approaches. Providing this flexibility is based on four basic principles, namely a unique generic specification model that allows the definition of a large variety of specific design products, transform...
