A data provenance framework is subject to security threats and risks, which increase the uncertainty, or lack of trust, in provenance information. Information assurance is challenged by incomplete information; one cannot exhaustively characterize all threats or all vulnerabilities. One technique that specifically incorporates a probabilistic notion of uncertainty is subjective logic. Subjective logic allows belief and uncertainty, due to incomplete information, to be specified and operated upon in a coherent manner. A mapping from the standard definition of information assurance to (...) a more quantitative subjective logic framework is suggested with a focus on the specific application of data provenance. Finally, specific consideration is given to the notion of uncertainty within subjective logic and its relation to information entropy. Information entropy is an alternative measure of uncertainty and a fundamental relationship is hypothesized between uncertainty in subjective logic and entropy. (shrink)
This volume captures the individuality, the national and personal identity, the cultural exchange, and the self-consciousness that have long been sensed as peculiarly potent in the Hellenistic world. The fields of history, literature, art, philosophy, and religion are each presented using the format of two essays followed by a response. Conveying the direction and focus of Hellenistic learning, eighteen leading scholars discuss issues of liberty versus domination, appropriation versus accommodation, the increasing diversity of citizen roles and the dress and (...) gesture appropriate to them, and the accompanying religious and philosophical ferment. The result is an arresting view of the incredible and unprecedented diversity of the Hellenistic world. (shrink)
Berkeley, Hume, and Russell rejected the traditional analysis of substances in terms of qualities which are supported by an "unknowable substratum." To them the proper alternative seemed obvious. Eliminate the substratum in which qualities are alleged to inhere, leaving a bundle of coexisting qualities--a view that we may call the Bundle Theory or BT. But by rejecting only part of the traditional substratum theory instead of replacing it entirely, Bundle Theories perpetuate certain confusions which are found in the Substratum Doctrine. (...) I examine two major types of BT developed by Russell and by G. F. Stout with the intention of showing that (1) the seemingly innocuous concept of "a quality" employed by these versions cannot be used to state their theories coherently, and (2) the fatal problems that the BT encounters point to a more satisfactory and interesting alternative to both the Substratum Doctrine and the BT. This is a view that I call the Qualified Particulars Theory. In a final section I draw morals from this discussion that apply to the analogous Humean view that a mind is a "bundle of perceptions and sensations.". (shrink)
In this thorough compendium, nineteen accomplished scholars explore, in some manner the values they find inherent in the world, their nature, and revelence through the thought of Frederick FerrZ. These essays, informed by the insights of FerrZ and coming from manifold perspectives—ethics, philosophy, theology, and environmental studies, advance an ambitious challenge to current intellectual and scholarly fashions.

This book taps the best American thinkers to answer the essential American question: How do we sustain our experiment in government of, by, and for the people? Authored by an extraordinary and politically diverse roster of public officials, scholars, and educators, these chapters describe our nation's civic education problem, assess its causes, offer an agenda for reform, and explain the high stakes at risk if we fail.
We began with three propositions: that people have a right not to be treated as mere means to the ends of others, that a woman who voluntarily becomes pregnant nevertheless has the right to an abortion, and that a woman who voluntarily gives birth does not have a right to abandon her child until she finds a substitute caretaker. These propositions initially seemed inconsistent, for the prohibition on treating others as mere means appeared to rule out the possibility of positive (...) rights, thus making it impossible to countenance the right to abort or the right not to be abandoned . But we have seen that the prohibition on treating people as mere means to the ends of others is best understood as ruling out basic positive rights while permitting derivative ones. Since a willing mother is responsible for bringing her child into the world in the first place, she cannot abandon it without violating its negative right not to be killed, and so such a child has a derivative positive right not to be abandoned. A pregnant woman, on the other hand, has a negative right not to have her body invaded, and from this negative right derives a positive right to abort her fetus, so long as doing so is not disproportionate to the seriousness of the threat . Therefore, far from being in conflict, propositions , , and have been shown to be in harmony with one another, the latter two being plausibly grounded in the first. Insofar as we have reason to accept , then, we have reason to accept and . Moreover, we have seen that a proper understanding of allows us to embed and in a larger moral perspective in which the limits of compulsory altruism are firmly drawn: enforceable rights to the use or assistance of others may be allowed into the moral domain only if they are “sponsored” by some negative right. Every putative positive right must find such a sponsor, or perish. (shrink)
F. H. Bradley (1846-1924) was considered in his day to be the greatest British philosopher since Hume. For modern philosophers he continues to be an important and influential figure. However, the opposition to metaphysical thinking throughout most of the twentieth century has somewhat eclipsed his important place in the history of British thought. Consequently, although there is renewed interest in his ideas and role in the development of Western philosophy, his writings are often hard to find. This collection unites all (...) of his published works, much of which has long been out of print, together with selected notebooks, articles, and correspondence from his previously unpublished remains. The set therefore provides the opportunity to view his entire philosophy, both in the breadth of its scope - from critical history and ethics through logic to metaphysics and epistemology - and in its historical development - from the earliest Hegelian writings to the later more psychological and pragmatic work. In addition the set features introductions to Bradley's writings, life and character, providing the framework to assess his permanent importance in the history of philosophy. --the first ever publication of all Bradley's works --includes 5 volumes of reset material, mostly never before published --a collecton that all serious philosophy libraries should have --extremely comprehensive new editorial matter --volumes 4 & 5 are indexed by subject and name --collects Bradley's correspondence, spanning 50 years, with Russell, Samuel Alexander, Bosanquet, Haldane, William James, Andrew Seth Pringle-Pattison, and many others --includes Bradley's notes on Green's lectures on ethics, selected undergraduate essays, notebooks preparatory of his major works, lists of what Bradley read, essays that never reached publication, inventory of Bradley's papers, and a catalogue of Bradley's personal library.

Long-range correlations are often manifested in the form of 1/fβ noise in a series of repeated measurements of the same neural or behavioral variable. Recent work has demonstrated that the magnitude and nature of these long-range correlations reliably capture individual differences and variation in task performance. In sensorimotor timing experiments, task characteristics such as tapping or circle drawing affect these long-range correlations during the production of isochronous time intervals. Such correlations are highly reproducible across multiple trials for (...) the same task but do not correlate between tasks. In the present experiment, we investigate whether two behavioral variables that are simultaneously controlled by the same participant in a given experimental condition can show such differentially organized fluctuations. In order to answer this question, 13 participants were asked to produce repetitive movements with their right index finger at a specified time interval and a specified force in the absence of an auditory metronome and visual feedback of force levels following a synchronization-continuation paradigm. Although participants showed high levels of consistency in the long-range correlations for each task component separately over multiple trials/observations, the long-range fluctuations for force and timing were found to show no correlations with each other for each participant. Cross recurrence quantification analyses revealed that there was limited shared structure between the timing and force time series data. Taken together, these results suggest that complex systems can organize multiple processes in a relatively independent manner while maintaining a high degree of reliability within one task parameter.
