Value and reasons for action are often cited by rationalists and moral realists as providing a desire-independent foundation for normativity. Those maintaining instead that normativity is dependent upon motivation often deny that anything called "value" or "reasons" exists. According to the interest-relational theory, something has value relative to some perspective of desire just in case it satisfies those desires, and a consideration is a reason for some action just in case it indicates that something of value will be accomplished by (...) that action. Value judgements therefore describe real properties of objects and actions, but have no normative significance independent of desires. ;It is argued that only the interest-relational theory accounts for the practical significance of value and reasons. Against the Kantian hypothesis of prescriptive rational norms, I attack the alleged instrumental norm or hypothetical imperative, showing that the normative force for taking the means to our ends is explicable in terms of our desire for the end, and not as a command of reason. This analysis also provides a solution to the puzzle concerning the connection between value judgement and motivation. While it is possible to hold value judgements without motivation, the connection is more than accidental. This is because value judgements are usually but not always made from the perspective of desires that actually motivate the speaker. In the normal case judgement entails motivation. But often we conversationally borrow external perspectives of desire, and subsequent judgements do not entail motivation. ;This analysis drives a critique of a common practice as a misuse of normative language. The "absolutist" attempts to use and, as philosopher, analyze normative language in such a way as to justify the imposition of certain interests over others. But these uses and analyses are incoherent---in denying relativity to particular desires they conflict with the actual meaning of these utterances, which is always indexed to some particular set of desires.

:Statisticians have proposed formal techniques for evaluation of treatments, often in the context of models that do not explicitly specify how treatments are generated. Under such procedures they run the risk of attributing causation in settings where the implementation neutrality condition required for causal interpretation of parameter estimates is not satisfied. When treatment assignments are explicitly modelled, as economists recommend, these issues can be formally analysed, and the existence of implementation neutrality, and therefore quantifiable causation, can be determined. Examples are (...) given. (shrink)

This paper proposes interpretations of the vexed notions of intensionality and intentionality and then investigates their resulting interrelations.The notion of intentionality comes from Brentano, in connection with his view that it can help us understand the mental. Setting aside Husserl’s basic definition of intentionality as not quite in line with Brentano’s explanatory purpose, this paper proposes that intentionality be defined in terms of inexistence and indeterminacy.It results that Brentano’s thesis (that all and only mental phenomena are intentional) will not be (...) strictly true. However, intentional descriptions will always be intensional, though not all intensional descriptions will be intentional. (shrink)

Active networking is an exciting new paradigm in digital networking that has the potential to revolutionize the manner in which communication takes place. It is an emerging technology, one in which new ideas are constantly being formulated and new topics of research are springing up even as this book is being written. This technology is very likely to appeal to a broad spectrum of users from academia and industry. Therefore, this book was written in a way that enables all these (...) groups to understand the impact of active networking in their sphere of interest. Information services managers, network administrators, and e-commerce developers would like to know the potential benefits of the new technology to their businesses, networks, and applications. The book introduces the basic active networking paradigm and its potential impacts on the future of information handling in general and on communications in particular. This is useful for forward-looking businesses that wish to actively participate in the development of active networks and ensure a head start in the integration of the technology in their future products, be they applications or networks. Areas in which active networking is likely to make significant impact are identified, and the reader is pointed to any related ongoing research efforts in the area. The book also provides a deeper insight into the active networking model for students and researchers, who seek challenging topics that define or extend frontiers of the technology. It describes basic components of the model, explains some of the terms used by the active networking community, and provides the reader with taxonomy of the research being conducted at the time this book was written. Current efforts are classified based on typical research areas such as mobility, security, and management. The intent is to introduce the serious reader to the background regarding some of the models adopted by the community, to outline outstanding issues concerning active networking, and to provide a snapshot of the fast-changing landscape in active networking research. Management is a very important issue in active networks because of its open nature. The latter half of the book explains the architectural concepts of a model for managing active networks and the motivation for a reference model that addresses limitations of the current network management framework by leveraging the powerful features of active networking to develop an integrated framework. It also describes a novel application enabled by active network technology called the Active Virtual Network Management Prediction (AVNMP) algorithm. AVNMP is a proactive management system; in other words, it provides the ability to solve a potential problem before it impacts the system by modeling network devices within the network itself and running that model ahead of real time.

This paper examines flexibility in ad hoc networks and suggests that, even with cross-layer design as a mechanism to improve adaptation, a fundamental limitation exists in the ability of a single optimization function, defined a priori, to adapt the network to meet all quality-of-service requirements. Thus, code implementing multiple algorithms will have to be positioned within the network. Active networking and programmable networking enable unprecedented autonomy and flexibility for ad hoc communication networks. However, in order to best leverage the results (...) of active and programmable networking, metrics that indicate the nature and location of required flexibility need to be developed. The primary contribution of this paper is to propose a metric that couples network topological rate of change with the ability of a generic service to move itself to an optimal location in concert with the changing network. This metric points to a fundamental tradeoff among adaptation (changing service location), performance (sophistication or estimated minimum code size of the service), and the network’s ability to tune itself to a changing ad hoc network topology.

Wireless ad hoc communication on the nanoscale will require thinking outside of the traditional radio spectrum. New applications will utilize new forms of wireless communication channels. For example, nanoscale communication will enable precise mechanisms for directly interacting with cells in vivo. Information may be sent to and from specific cells within the body, allowing detection and healing of diseases on the cellular scale. From a medical standpoint, the use of current wireless techniques to communicate with implants is unacceptable for many (...) reasons, including bulky size, inability to use magnetic resonance imaging after implantation, potential radiation damage, surgical invasiveness, need to recharge/replace power, post-operative pain and long recovery times, and reduced quality of life for the patient. Better, more humane in vivo implant communication is needed. Development of both biological and engineered nanomachines is progressing; such machines will need to communicate [1]. Unfortunately, networking vast collections of nanoscale sensors and robots using current techniques, including wireless techniques, is not possible without communication mechanisms that exceed nanoscale volumes.

William of Ockham discussed the fallacy of amphiboly twice in his writings. The first treatment was in his Expositio super libros Elenchorum, where he simply presents Aristotle’s treatment, updates it with some Latin examples, and tells us it is not too important, since we do not often run into cases of ambiguity of thiskind. Later, in his Summa logicae, however, he extends his treatment appreciably. He here includes under ambiguous statements philosophical and theological sentences which are improperly stated. Led by (...) Aristotle, Augustine and Anselm, Ockham finds that in their writings they give us instances of improper statements which need to be restated properly before they can be evaluated as true or false. These leads provide for Ockham a key to unlocking the teaching treasures of the Ancients. (shrink)

:The most basic question one can ask of a model is ‘What is the effect on variable y2 of variable y1?’ Causation is ‘implementation neutral’ when all interventions on external variables that lead to a given change in y1 have the same effect on y2, so that the effect of y1 on y2 is defined unambiguously. Familiar ideas of causal analysis do not apply when causation is implementation neutral. For example, a cause variable cannot be linked to an effect variable (...) by both a direct path and a distinct indirect path. Discussion of empirical aspects of implementation neutrality leads to further unexpected results, such as that if one variable causes another the coefficient representing that causal link is always identified.

Modern developments in philosophy have provided us with tools, logical and methodological, that were not available to Medieval thinkers - a development that has its dangers as well as opportunities. Modern tools allow one to penetrate old texts and analyze old problems in new ways, offering interpretations that the old thinkers could not have known. But unless one remains sensitive to the fact that language has undergone changes, bringing with it a shift in the meaning of terminology, one can easily (...) perpetrate an anachronism. Yet there is a growing need to bring modern tools and to bear on the struggle for greater understanding of the problems studied and the solutions found by the ancient scholars. If we remain sensitive to the dangers, this openness to new methods can be expected to widen our perspectives and deepen our knowledge of old material. The focus in the present volume is on problems in Medieval and contemporary philosophy of religion. (shrink)

This paper describes the design of a control and management network (orderwire) for a mobile wireless Asynchronous Transfer Mode (ATM) network. This mobile wireless ATM network is part of the Rapidly Deployable Radio Network (RDRN). The orderwire system consists of a packet radio network which overlays the mobile wireless ATM network, each network element in this network uses Global Positioning System (GPS) information to control a beamforming antenna subsystem which provides for spatial reuse. This paper also proposes a novel Virtual (...) Network Configuration (VNC) algorithm for predictive network configuration. A mobile ATM Private Network-Network Interface (PNNI) based on VNC is also discussed. Finally, as a prelude to the system implementation, results of a Maisie simulation of the orderwire system are discussed. (shrink)

This paper extends a stochastic theory for buffer fill distribution for multiple “on‘ and “off‘ sources to a mobile environment. Queue fill distribution is described by a set of differential equations assuming sources alternate asynchronously between exponentially distributed periods in “on‘ and “off‘ states. This paper includes the probabilities that mobile sources have links to a given queue. The sources represent mobile user nodes, and the queue represents the capacity of a switch. This paper presents a method of analysis which (...) uses mobile parameters such as speed, call rates per unit area, cell area, and call duration and determines queue fill distribution at the ATM cell level. The analytic results are compared with simulation results. (shrink)

This is a brief letter outlining speculative ideas for semantic web reasoning about information assurance. Much work has been done on the development of semantic web applications for reasoning about information assurance. A significant portion of this work is focused upon semantic web ontologies and reasoning about security policies and the underlying implementation of those policies. While numerous semantic web-based security policy ontologies and reasoners exist, both academically and commercially, I will briefly focus on ideas related to solutions to the (...) problem of managing semantic web rules using algorithmic information theory.

The Middle Ages is often viewed as a period of low intellectual achievement. The name itself refers to the time between the high philosophical and literary accomplishments of the Greco-Roman world and the technological advances that were achieved and philosophical and theological alternatives that were formulated in the modern world that followed. However, having produced such great philosophers as Anselm, Peter Abelard, John Duns Scotus, William of Ockham, Peter Lombard, and the towering Thomas Aquinas, it hardly seems fair to label (...) the medieval period as such. Examining the influence of ancient Greek philosophy as well as of the Arabian and Hebrew scholars who transmitted it, the Historical Dictionary of Medieval Philosophy and Theology presents the philosophy of the Christian West from the 9th to the early 17th century. This is accomplished through a chronology, an introduction, appendixes, a bibliography, and hundreds of cross-referenced dictionary entries on the philosophers, concepts, issues, institutions, and events, making this an important reference for the study of the progression of human thought.
