Traditional accounts of belief change have been criticized for placing undue emphasis on the new belief provided as input. A recent proposal to address such issues is a framework for non-prioritized belief change based on default theories (Ghose and Goebel, 1998). A novel feature of this approach is the introduction of disbeliefs alongside beliefs which allows for a view of belief contraction as independently useful, instead of just being seen as an intermediate step in the process of belief revision. (...) This approach is, however, restrictive in assuming a linear ordering of reliability on the received inputs. In this paper, we replace the linear ordering with a preference ranking on inputs from which a total preorder on inputs can be induced. This extension brings along with it the problem of dealing with inputs of equal rank. We provide a semantic solution to this problem which contains, as a special case, AGM belief change on closed theories. (shrink)
This book deals with the major philosophical issues in the theoretical framework of Artificial Intelligence (AI) in particular and cognitive science in general.
Corporate social responsibility (CSR) is a dramatically expanding area of activity for managers and academics. Consumer demand for responsibly produced and fair trade goods is swelling, resulting in increased demands for CSR activity and information. Assets under professional management and invested with a social responsibility focus have also grown dramatically over the last 10 years. Investors choosing social responsibility investment strategies require access to information not provided through traditional financial statements and analyses. At the same time, a group of mainstream (...) institutional investors has encouraged a movement to incorporate environmental, social, and governance information into equity analysis, and multi-stakeholder groups have supported enhanced business reporting on these issues. The majority of research in this area has been performed on European and Australian firms. We expand on this literature by exploring the CSR disclosure practices of a size-and industry-stratified sample of 50 publicly traded U. S. firms, performing a content analysis on the complete identifiable public information portfolio provided by these firms during 2004. CSR activity was disclosed by most firms in the sample, and was included in nearly half of public disclosures made during that year by the sample firms. Areas of particular emphasis are community matters, health and safety, diversity and human resources (HR) matters, and environmental programs. The primary venues of disclosure are mass media releases such as corporate websites and press releases, followed closely by disclosures contained in mandatory filings. Consistent with prior research, we identify industry effects in terms of content, emphasis, and reporting format choices. Unlike prior research, we can offer only mixed evidence on the existence of a size effect. The disclosure frequency and emphasis is significantly different for the largest one-fifth of the firms, but no identifiable trends are present within the rest of the sample. There are, however, identifiable size effects with respect to reporting format choice. Use of websites is positively related to firm size, while the use of mandatory filings is negatively related to firm size. Finally, and also consistent with prior literature, we document a generally self-laudatory tone in the content of CSR disclosures for the sample firms. (shrink)
Recent years have featured a spate of regulatory action pertaining to the development and/or disclosure of corporate governance structures in response to financial scandals resulting in part from governance failures. During the same period, corporate governance activists and institutional investors increasingly have called for increased voluntary governance disclosure. Despite this attention, there have been relatively few comprehensive studies of governance disclosure practices and response to the regulation. In this study, we examine a sample of 50 U.S. firms and their public (...) disclosure packages from 2004. We find a high degree of variability in the presentation and reporting format choices for many elements of the governance structure. This variability includes several items for which disclosure is mandated by regulators or legislative action. In particular, smaller firms offer fewer disclosures pertaining to independence, board selection procedures, and oversight of management (including whistleblowing procedures). There are also trends associated with board characteristics: boards that are less independent offer fewer disclosures of independence and management oversight matters. Moreover, large firms provide more disclosures of independence standards, board selection procedures, audit committee matters, management control systems, other committee matters, and whistleblowing procedures but do not appear to have a strictly superior information environment when compared to smaller firms. The findings raise questions about compliance with regulatory requirements and the degree to which conflicts of interest between managers and directors are being controlled. While there have been notable improvements in the information environment of governance disclosures, there remain structural issues that may possess negative ramifications for stakeholders. (shrink)
We provide a formal study of belief retraction operators that do not necessarily satisfy the (Inclusion) postulate. Our intuition is that a rational description of belief change must do justice to cases in which dropping a belief can lead to the inclusion, or ‘liberation’, of others in an agent's corpus. We provide two models of liberation via retraction operators: ρ-liberation and linear liberation. We show that the class of ρ-liberation operators is included in the class of linear ones and provide (...) axiomatic characterisations for each class. We show how any retraction operator (including the liberation operators) can be ‘converted’ into either a withdrawal operator (i.e., satisfying (Inclusion)) or a revision operator via (a slight variant of) the Harper Identity and the Levi Identity respectively.

The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We argue briefly against putative counterexamples to the axiom—while agreeing that some of their insight deserves to be preserved—and present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions. This makes iterated revision possible and renders explicit the connection between iterated belief change and the axiom of recovery. We provide a representation theorem (...) that connects the semantic conditions we impose on iterated revision and our additional syntactical properties. We show interesting similarities between our framework and that of Darwiche–Pearl (Artificial Intelligence 89:1–29 1997). In particular, we show that intuitions underlying the controversial (C2) postulate are captured by the recovery axiom and our recovery-like postulates (the latter can be seen as weakenings of (C2)). We present postulates for contraction, in the same spirit as the Darwiche–Pearl postulates for revision, and provide a theorem that connects our syntactic postulates with a set of semantic conditions. Lastly, we show a connection between the contraction postulates and a generalisation of the recovery axiom. (shrink)
Virginia Held argues that terrorism can be justified in some instances. But unlike standard, consequentialist justifications, hers is deontological. This paper critically examines her argument. It explores how the values of fairness, responsibility, and desert can serve to justify acts of terrorism. In doing so, two interpretations of her account are considered: a responsibility-insensitive and a responsibility-sensitive interpretation. On the first, her argument collapses into a consequentialist justification. On the second, it relies on an implausible conception of responsibility. Either way, (...) her argument fails as a distinctly deontological defense of terrorism. (shrink)
herent and rational way. Several proposals have been made for information merging in which it is possible to encode the preferences of sources (Benferhat, Dubois, Prade, & Williams, 1999; Benferhat, Dubois, Kaci, & Prade, 2000; Lafage & Lang, 2000; Meyer, 2000, 2001; Andreka, Ryan, & Schobbens, 2001). Information merging has much in common with social choice theory, which aims to define operations reflecting the preferences of a society from the individual preferences of the members of the society. Given this connection, (...) frameworks for information merging should provide satisfactory resolutions of problems raised in social choice theory. We investigate the link between the merging of epistemic states and two important results in social choice theory. We show that Arrow’s well-known impossibility theorem (Arrow, 1963) does not hold in merging frameworks when the preferences of sources are represented in terms of epistemic states. This is achieved by providing a consistent set of properties for merging from which Arrow-like properties can be derived. Similarly, by extending these to a consistent framework which includes properties corresponding to the notion of being strategy-proof, we show that results due to Gibbard and Satterthwaite (Gibbard, 1973; Satterthwaite, 1973, 1975) and other (Benoit, 2000; Barber´a, Dutta, & Sen, 2000) do not hold in merging frameworks.

While robotics has benefited from inspiration gained from biology, the opposite is not the case: there are few if any cases in which robotic models have lead to genuine insight into biology. We analyze the reasons why biorobotics has been essentially a one-way street. We argue that the development of better tools is essential for progress in this field.

The term ?boson? appears in almost all discussions on elementary particles and carries a reference to the name of Satyendra Nath Bose, the co-founder of quantum statistics. Yet, in spite of this wide use of a term coined after his name, Bose himself remains a shadowy figure in the history of science. This article is an attempt to reconstruct how Bose arrived at the statistics for which he is now remembered, and his subsequent two-year brief role in international science. (...) Through the lens of Bose's practice, I seek to grasp the contexts of those peripheral scientists who enter the practice of science from outside of the main group, and yet somehow manage to create a lasting contribution within it.

This article deals with the complex personality and legacy of a mysterious saint known both as a Sufī (Ḥājji Ratan) and a Nāth Yogī (Ratannāth) and links his multiple identity as well as the religious movement originated from him, to the specific cultural context of the former North-West Indian provinces. The first part is devoted to Ratan in the Nāth Yogī tradition, the second to his many facets in the Muslim tradition, in connection with his dargāh in the Panjabi town (...) of Bhatinda. The third and main part explores a particular movement, the Har Śri Nāth tradition. Presently centered around a “ dargāh mandir ” in Delhi, this movement, with its two branches issued from Ratan and from his “son” Kāyānāth, was rooted in what is now Pakistan. The influence of location and history has led to many peculiarities which lead us to stress the blurred boundaries between Islam and Hinduism and the essential part played by charismatic figures in the construction of religious identities.

Abstract While much has been written about science and the Abrahamic religious traditions, there is little about the Hindu tradition and science. We examine two recent authors who have explored the relationship between the two, in one case across the full spectrum of Indian history, and in the other with a specific focus on the Bhāgavata Purāṇa, a ninth- to eleventh-century CE document centered on the Lord Krishna. These two publications are compared with a symposium of articles by scientists and (...) scholars of the Hindu tradition that consider both science and religion heuristically in terms of “knowing the unknowable.” Each contribution explores this concept in accordance with the scientific or religious topic's internal self-understanding, without any cross-fertilization (“cherry picking”) across the boundaries. Finally, we consider the author's own approach, which is intermediate between the previous mentioned in that it reviews the work of Hindu scientists who shaped the course of their research in accordance with their Vedāntic beliefs. These include Satyendra Nath Bose, who collaborated with Einstein on his quest for a unified field theory, and gave his name to a class of fundamental particles called bosons. (shrink)
In his book, The Logic of Democracy, T.L. Thor son has published a chapter entitled "Majority Rule and Minority Rights". In this paper he has pointed out a controversy which has arisen between "natural rights democrats" and "majority rule democrats." In this paper I argue that elected representatives represent the majority and their rule can be called the rule of the majority so long they can protect the rights of individuals. This is why the natural rights of man are more (...) fundamental and essential than majority rule. In conclusion, I insist that neither "natural rights" nor "majority rule" can be called the elements of democracy. If the former and the latter could have been understood as the end of democracy and the means to achieve the end, respectively, then the controversy would not have arisen. (shrink)
In their book entitled “Democracy and the American Party System” Austin Ranney and (Willmoore Kendall have brought a charge again the pluralists that they denied the desirability of creating sovereign state and as such, according to them, they were opponents of democracy as well as of the very idea of government. The aim of this paper is to refute their charge and thereby to establish the view that the pluralists are in fact strong supporters of democracy in the real sense (...) of the term and of popular sovereignty. What did most of them was that they made an attempt to bring to light the fact that democracy, as it is being practiced almost everywhere in the world, ultimately leads to denial of popular sovereignty, the basic element of self-government. Self-government can best be realized where the people is the real sovereign neither the state nor the numerical majority. And the government formed by the representatives elected in a traditional party-based election does not therefore, mean self-government. It can at best be called the government of the majority. Majority rule does not anyway mean democracy. It may be called ‘numbersocracy’ after the proper terminology of Ranney and Kendall. Democracy, de facto, is nothing other than majority rule that is best termed by John Calhoun, the ex-vice-president of the U.S.A, as the ‘rule by numerical majority’. ‘Numerical’ majority”, says he, “is not the people”. I strongly adhere to the pluralists’ view and therefore, conclude with an insistent assertion that numerical majority rule in disguise of democracy has in fact ruled out popular sovereignty. (shrink)
This book examines the role of the Bhagavadgita in the formation of nationalist thought. It analyses how the text was deployed as the central terrain of nationalist contestation and in the diverse ethico-moral mappings of the nation. Focusing on Balgangadhar Tilak, Swami Vivekananda, Mahatma Gandhi, Aurobindo Ghose, Vinoba Bhave and B.R. Ambedkar as the representatives of different strands of nationalist discourse, this volume probes their reflections on Gita. The author argues that Bhagavadgita opened up several possible understandings without necessarily (...) eliminating one another and that Indian nationalism could also be understood as a commentary on the text. -/- This book will be of considerable interest to scholars and students of religion, philosophy, and modern Indian history particularly those concerned with nationalist movement.
