We consider Effort Games, a game-theoretic model of cooperation in open environments, which is a variant of the principal-agent problem from economic theory. In our multiagent domain, a common project depends on various tasks; carrying out certain subsets of the tasks completes the project successfully, while carrying out other subsets does not. The probability of carrying out a task is higher when the agent in charge of it exerts effort, at a certain cost for that agent. A central authority, called (...) the principal, attempts to incentivize agents to exert effort, but can only reward agents based on the success of the entire project.We model this domain as a normal form game, where the payoffs for each strategy profile are defined based on the different probabilities of carrying out each task and on the boolean function that defines which task subsets complete the project, and which do not. We view this boolean function as a simple coalitional game, and call this game the underlying coalitional game. We suggest the Price of Myopia as a measure of the influence the model of rationality has on the minimal payments the principal has to make in order to motivate the agents in such a domain to exert effort.We consider the computational complexity of testing whether exerting effort is a dominant strategy for an agent, and of finding a reward strategy for this domain, using either a dominant strategy equilibrium or using iterated elimination of dominated strategies. We show these problems are generally #P-hard, and that they are at least as computationally hard as calculating the Banzhaf power index in the underlying coalitional game. We also show that in a certain restricted domain, where the underlying coalitional game is a weighted voting game with certain properties, it is possible to solve all of the above problems in polynomial time. We give bounds on PoM in weighted voting effort games, and provide simulation results regarding PoM in another restricted class of effort games, namely effort games played over Series-Parallel Graphs.

In this paper we review some properties of fuzzy observables, mainly as realized by commutative positive operator valued measures. In this context we discuss two representation theorems for commutative positive operator valued measures in terms of projection valued measures and describe, in some detail, the general notion of fuzzification. We also make some related observations on joint measurements.

Central aspects of Hume’s proposed “system of the sciences” as described in the Treatise are modeled on Newton’s Principia. But, as recent scholarship has suggested, Hume’s Treatise also bears a deeply subversive message with respect to Newtonian science. This chapter offers a revised overview of what Hume takes from Newton and what he rejects: The first part of the chapter argues that in the Treatise Hume adopts a version of Newton’s “analytic and synthetic method” for philosophy, thereby placing a distinctively (...) Newtonian form of explanatory reduction at the center of his own philosophical method. The second part of the chapter, on the other hand, shows that many of the most important aspects of Hume’s argument in Book 1 of the Treatise can be understood as critical of core conceptual and ontological commitments of Newton’s mechanics as developed in the Principia.

A Dirac-type equation on R×S 3 topology is derived. It is a generalization of the previously obtained Klein-Gordon-type, Schrödinger-type, and Weyl-type equations, and reduces to the latter in the appropriate limit. The (discrete) energy spectrum is found and the corresponding complete set of solutions is given as expansions in terms of the matrix elements of the irreducible representations of the group SU 2 . Finally, the properties of the solutions are discussed.

A Weyl-type equation onR×S 3 topology is derived, as a generalization to previously obtained Klein-Gordon- and Schrödinger-type equations for the same topology. The general solution of the new equation is given as an expansion in the matrix elements of the irreducible representations of the groupSU 2. The properties of the solutions are discussed.

We extend to curved space-time the field theory on R×S3 topology in which field equations were obtained for scalar particles, spin one-half particles, the electromagnetic field of magnetic moments, an SU2 gauge theory, and a Schrödinger-type equation, as compared to ordinary field equations that are formulated on a Minkowskian metric. The theory obtained is an angular-momentum representation of gravitation. Gravitational field equations are presented and compared to the Einstein field equations, and the mathematical and physical similarity and differences between them (...) are pointed out. The problem of motion is discussed, and the equations of motion of a rigid body are developed and given explicitly. One result which is worth emphazing is that while general relativity theory yields Newton's law of motion in the lowest approximation, our theory gives Euler's equations of motion for a rigid body in its lowest approximation.

The equations of electrodynamics for the interactions between magnetic moments are written on R×S3 topology rather than on Minkowskian space-time manifold of ordinary Maxwell's equations. The new field equations are an extension of the previously obtained Klein-Gordon-type, Schrödinger-type, Weyl-type, and Dirac-type equations. The concept of the magnetic moment in our case takes over that of the charge in ordinary electrodynamics as the fundamental entity. The new equations have R×S3 invariance as compared to the Lorentz invariance of Maxwell's equations. The solutions (...) of the new field equations are given. In this theory the divergence of the electric field vanishes whereas that of the magnetic field does not. (shrink)

A gauge theory on R×S 3 topology is developed. It is a generalization to the previously obtained field theory on R×S 3 topology and in which equations of motion were obtained for a scalar particle, a spin one-half particle, the electromagnetic field of magnetic moments, and a Shrödinger-type equation, as compared to ordinary field equations defined on a Minkowskian manifold. The new gauge field equations are presented and compared to the ordinary Yang-Mills field equations, and the mathematical and physical differences (...) between them are discussed. (shrink)

What is inequality? In the late 1990s there was an explosion of interest in the subject that yielded a substantial body of formal tools and results for income-distribution analysis. Nearly all of this is founded on a small set of core assumptions - such as the Principle of Transfers, scale independence, the population principle∑ - that are used to give meaning to specific concepts of inequality measurement, inequality ranking and, indeed, to inequality itself. But does the standard axiomatic structure coincide (...) with public perceptions of inequality? Or is the economist's concept of inequality a thing apart, perpetuated through serial brainwashing in the way the subject is studied and taught? In this 1999 book, Amiel and Cowell examine the evidence from a large international questionnaire experiment using student respondents. Along with basic 'cake-sharing' issues, related questions involving social-welfare rankings, the relationship between inequality and overall income growth and the meaning of poverty comparisons are considered.

The age of maturity of children to consent for medical research is under debate, as different authorities regard the capacity of young teenagers as either satisfactory or not to grant consent without parental participation in the process. The present paper contrasts the generally accepted guideline for ethics in paediatric research in Canada with what the same children are allowed and expected to be able to do as babysitters. This comparison reveals deep incongruences in the way the maturity of the same (...) children is appreciated for two different tasks. (shrink)

This book describes Carmeli's cosmological general and special relativity theory, along with Einstein's general and special relativity. These theories are discussed in the context of Moshe Carmeli's original research, in which velocity is introduced as an additional independent dimension. Four- and five-dimensional spaces are considered, and the five-dimensional braneworld theory is presented. The Tully-Fisher law is obtained directly from the theory, and thus it is found that there is no necessity to assume the existence of dark matter in (...) the halo of galaxies, nor in galaxy clusters.The book gives the derivation of the Lorentz transformation, which is used in both Einstein's special relativity and Carmeli's cosmological special relativity theory. The text also provides the mathematical theory of curved space?time geometry, which is necessary to describe both Einstein's general relativity and Carmeli's cosmological general relativity. A comparison between the dynamical and kinematic aspects of the expansion of the universe is made. Comparison is also made between the Friedmann-Robertson-Walker theory and the Carmeli theory. And neither is it necessary to assume the existence of dark matter to correctly describe the expansion of the cosmos. (shrink)

As a discourse genre, statements of purpose are characterized by their occluded status in the academy and by their hybrid nature. Statements of purpose are required in applications for a place in a postgraduate course, and they are requested to obtain information about the academic and professional background and skills of each applicant. A study of the genre’s linguistic and textual features is needed in Spanish to discover and understand writers’ and readers’ perception of this genre. A corpus of 50 (...) motivation letters in Spanish is analyzed here. We study the distinguishing macro- and microtextual features of this particular genre and co-occurrences between both kinds of features. At the macrotextual level, statements of purpose display prototypical rhetorical moves, which can be classified as writers’ moves and readers’ moves. On the microtextual level, modalization resources and discourse markers are discussed. This multiple perspectives analysis of the corpus shows evidence of significant co-occurrences among modalization, discourse markers, and rhetorical moves. Writers’ ideal representations of this discourse genre, which spans the academic and professional fields, can also be deduced. (shrink)

This paper studies the role that known bounds on message transmission times in a computer network play on the evolution of the epistemic state over time. A connection to cones of causal influence analogous to, and more general than, light cones is presented. Focusing on lower bounds on message transmission times, an analysis is presented of how knowledge about when others are guaranteed to be ignorant about an event of interest can arise. This has implications in competitive settings, in which (...) knowing about another’s ignorance can provide an advantage. (shrink)

The American Declaration of Independence served as a starting point for the drafting of the Israeli Declaration of Independence of 1948. Most of the original content was lost in the long process of translation and adaptation, but, using David Armitage’s recent terminology, the Israeli text remained as "generically promiscuous" as its predecessor, combining a "manifesto" of justifications for the assumption of sovereignty, a formal proclamation and a proto-Bill of Rights. This Article depicts the work of Mordechai Beham, the Israeli Declaration’s (...) first draftsman, as a remarkable exercise in choosing contemporary, locally-valid "answers" to the fundamental "questions" posed by Thomas Jefferson and his contemporaries in 18th century America on human values, national identity, statehood, and God. The analysis is partially based in the current debate on "legal transplantation," arguing that the outstanding success of the Israeli Declaration stems from both the quality of the American original and the massive work of adaptation to Israeli soil.

The effort to rid criminal responsibility of factors beyond the agent’s control created an opportunity for a new balance in the law of attempt between aggravated penalties and full exoneration for voluntary renunciation. The present analysis claims that the opportunity has been missed both in Israel and in the United States because of an unwarranted concern for the moral tenor of renunciation. Analysis of the difference between successes and failures in renunciation cases is offered in support of the proposition that (...) the proper balance between ex post and ex ante considerations is only applied where courts empathize with the victims of specific crimes. In other cases, immediate victims are readily used as means to prevent uncertain future crime. The claim is also made that concern with the moral tenor of renunciation creates an anomaly in modern criminal law. While the decision to initiate a crime act is judged on ever narrower pictures of character and motive, the decision to abandon it before actual harm is inflicted increasingly attracts interest in the inner processes behind it. I claim that the anomaly manifests the danger of blurring the line between reality and fantasy when the struggle against luck is not properly checked. (shrink)

The ArgumentOne disconcerting aspect of the role of culture in shaping human suffering is the gap between the explanatory models of therapists and patients in multicultural settings. This gap is particularly noted in working with Jewish ultra–Orthodox psychiatric patients whose idioms of distress are often derived from a sacred reality not easily reconcilable with psychomedical reality. To meet the challenge to therapeutic efficacy that this incompatibility may pose, we propose a culturally sensitive therapy based on strategic principles that focus on (...) the patient's mythic world and religious idioms of distress as the kernel of therapeutic interventions. Using one case of post–traumatic stress disorder (PTSD) as illustration, we seek to show how the religious symbols through which the patient's distress was articulated may be manipulated to effect cure. The case highlights the narrative quality of both illness construction and self–reconstruction. (shrink)

Section 170 of the U.S. Internal Revenue Code is known as the “charitable contribution deduction.” This Article explores the section’s rationale as well as its effect on income/wealth distribution. It reaches the conclusion that the deduction can be justified on efficiency and democracy grounds, but is not “charitable,” as its distributive effects are neutral or even regressive.

In a previous article I argued that tipping facilitates tax evasion, hurts employees’ financial security in the long run, and is a form of negative externality imposed by wealthy people on the rest of society. In this Article I try to understand the reasons for the greater popularity of the norm in the U.S. compared to other countries, suggesting it may be related to the U.S. cultural preference for linking redistribution with work requirements, relatively high income inequality and consumerism. To (...) that end, I further develop the negative externality argument suggested in the previous article by looking at trends in income inequality in the U.S. and by interpreting the global distribution of the norm through the prism of my inequality/negative externality argument. I then look at the tax treatment of tips in various countries in search of a pattern that supports the differences in social norms. (shrink)

I address three key questions in Jewish theology that have come up in readers’ criticism of my book The Philosophy of Hebrew Scripture: How should we think about God’s revelation to man if, as I have proposed, the sharp distinction between divine revelation and human reason is alien to the Hebrew Bible and classical rabbinic sources? Is the biblical Law of Moses intended to be a description of natural law, suggesting the path to life and the good for all nations? (...) And what should be the role of the Jewish theologian, given the overwhelming prevalence of Christian conceptions of God and Scripture in contemporary theological discourse. (shrink)

In this book Yoram Lubling and Eric Evans offer a Deweyan reconstruction of our philosophical understanding of well-being. They begin with Dewey's critique of the philosophical fallacy to examine the legitimacy and value of theories of well-being offered by traditional philosophy. However, such theories fail to provide an authentic account of well-being due to a false understanding of "experience" as either epistemic or cognitive. Next, using Dewey's theory of experience, they reconstruct happiness as the target for evaluation of well-being. (...) This leads them to reject the traditional view of a private encapsulated self, and to offer in its place a "transactionally situated self" which is an embodied, enculturated agent. Through their emphasis on the importance of the qualitative aspects of Dewey's understanding of a situation, the "pervasive quality of the situation" emerges as the most plausible criterion for the evaluation of well-being. The authors use Dewey's theories of inquiry, ethics, value and art to establish the naturalistic conditions under which such "pervasive quality" enters into a situation as either settled or unsettled, in other words, as peace in motion. Consequently, a "problematic situation" becomes the primary condition under which all inquiry initiates whether it is in the context of science, ethics, values, art or ordinary living. Lubling and Evans conclude that a Deweyan account of well-being involves "embodied knowing" instead of the traditional view of cognitive knowledge. By using such an account, it is possible to explain the conditions and mechanisms under which well-being contributes to the enlargement and enrichment of individual and collective human experience.

The Person Vanishes argues that despite John Dewey's failure to articulate «an adequate theory of personality», his writings provide at least a theory-sketch of human personality consistent with the assumptions that framed his philosophical outlook. Recognizing the new developments in society, science, and the arts, Dewey argues for the necessity of a Copernican revolution in our understanding of the human self; from the monadic and minimalist self of the Cartesian-Newtonian modernist tradition to a relational and processual model of selfhood consonant (...) with the press of post-modernist historical experience. As a field and activity conception, Dewey's self emerges as a nexus of relational energizing, genuinely moored in a cultural surrounding in which ongoing creative reconstruction becomes the mark and criterion of the self's health and growth. What vanishes in Dewey's reconstruction is not the self as such, but only the entitative, substantive self of early modernism. Dewey's understanding of the self is grounded in the conviction that philosophy must begin its inquiry from the ordinary experience of plain men and women. The Person Vanishes examines Dewey's participatory notion of deliberation, what he calls «dramatic rehearsal», by using the Israeli-Palestinian conflict as a case study. The analysis attempts to cash out the personal and collective habits, as well as the different modalities of ends, facts, and values that diagram the existential dimensions of this problematic situation. Contrary to traditional dualistic and spectatorial accounts of deliberation, Dewey's «dramatic rehearsal» shows the complexity of decision-making when the genuine limitations of daily life are taken seriously. The attempt to march to Dewey's participatory philosophy reveals the escapist nature of all dualistic philosophical traditions and the reason for their continuous failure to resolve concrete social and personal conflicts.

A theory of relativity, along with its appropriate group of Lorentz-type transformations, is presented. The theory is developed on a metric withR×S 3 topology as compared to ordinary relativity defined on the familiar Minkowskian metric. The proposed theory is neither the ordinary special theory of relativity (since it deals with noninertial coordinate systems) nor the general theory of relativity (since it is not a dynamical theory of gravitation). The theory predicts, among other things, that finite-mass particles in nature have maximum (...) rotational velocities, a prediction highly supported by recent experiments on 14 nuclei, such as 159 Yb that survives fission with angular velocities of up to 0.9 of the predicted value but does not reach it.

Objective: To explore the relationship between the presentation of suffering and support for euthanasia in the British news media.Method: Data was retrieved by searching the British newspaper database LexisNexis from 1996 to 2000. Twenty-nine articles covering three cases of family assisted suicide were found. Presentations of suffering were analysed employing Heidegger’s distinction between technological ordering and poetic revealing.Findings: With few exceptions, the press constructed the complex terrain of FAS as an orderly or orderable performance. This was enabled by containing the (...) contradictions of FAS through a number of journalistic strategies: treating degenerative dying as an aberrant condition, smoothing over botched attempts, locating the object of ethical evaluation in persons, not contexts, abbreviating the decision making process, constructing community consensus and marginalising opposing views.Conclusion: The findings of this study support the view that news reporting of FAS is not neutral or inconsequential. In particular, those reports presenting FAS as an orderly, rational performance were biased in favor of technical solutions by way of the legalisation of euthanasia and/or the involvement of medical professionals. In contrast, while news reports sensitive to contradiction did not necessarily oppose euthanasia, they were less inclined to overtly support technical solutions, recognising the importance of a trial to address the complexity of FAS.

In this Article we attempt to narrow the gap between developed and developing countries’ respective perceptions of justice in the context of climate change. We show that, in spite of its intuitive appeal, the equal per-capita argument is not grounded in any general moral principle and therefore cannot provide an answer to the question regarding what would be a fair allocation of emission rights. We argue that the underlying moral theory is global distributive justice theory, which unfortunately can only be (...) of very limited help. We briefly discuss the various particular principles/considerations that are offered in the literature either in support or in criticism of the equal percapita allocation and find that upon close analysis they generally support the developing countries’ view, but not a per-capita allocation of emission rights. We conclude with a practical suggestion. (shrink)

This paper proposes an intermediate account of personhood, based on the capacity to participate in intersubjective interactions. We articulate our proposal as a reply to liberal and restrictive accounts, taking Mark Rowlands’ and Stephen Darwall’s proposals as contemporary representatives of each view, respectively. We argue that both accounts fall short of dealing with borderline cases and defend our intermediate view: The criteria of personhood based on the second-person perspective of mental state attribution. According to it, a person should be able (...) to participate in intersubjective interactions. We apply our proposal to the borderline cases of non-human primates and human infants. (shrink)

The article asserts that verses 124–130 in the second sūrah of the Qurʾān (al-Baqara/“the Cow”) alludes to the biblical precept (Genesis 17) but presents the practice as a custom that has no special virtues, and certainly not those the Jews ascribed to it. It then claims that circumcision is identified as one of Abraham’s trials, which are mentioned in the Qurʾān and thus part of early Islam, and that this idea did not arise in the Middle Ages.

This study of internal auditors and auditees, who engage in both financial and operational internal audits in Israel, extends theory and research on internal audits in organizational units. It develops and tests a model that examines the role of top management and internal auditors in facilitating learning from internal audits and driving perceived performance improvement. We argue that support from the top management for the internal audit as well as the auditor’s capacity facilitate learning from audits and help audited units (...) to improve ethicality, efficiency, and effectiveness in organizations. The results of time-lagged survey data provide general support for the hypothesized indirect relationships between auditor capacity, auditor–auditee relational exchanges, learning from audits, and three different perceived performance measures: ethical behavior, efficiency, and effectiveness. We discuss the implications for research on internal audits, proactive learning, ethics, and performance improvement of organizational units in the public sector. (shrink)

In this paper, we take Darwall’s analytical project of the second-person standpoint as the starting point for a naturalistic project about our moral psychology. In his project, Darwall contends that our moral notions constitutively imply the perspective of second-personal interaction, i.e. the interaction of two mutually recognized agents who make and acknowledge claims on one another. This allows him to explain the distinctive purported authority of morality. Yet a naturalized interpretation of it has potential as an account of our moral (...) psychology. We propose a naturalistic interpretation of Darwall’s work to address some of the main issues about our moral psychology. First, we explain why moral norms motivate us; namely, because of these second-personal relations. We provide a naturalized version of this solution. Second, we articulate how intersubjective interactions take place effectively; grounding duties to particular other subjects, and being related to distinctive moral emotions. Third, we address the question of the limits of the moral community, proposing that it comprises all agents capable of second-personal interactions. Finally, we explain the emergence of community norms through intersubjective interaction. Since all group members can adopt alternatively the second-personal stance to each other, demands are sanctioned and recognized in a triangulation process which explains the emergence of group norms.

Building on the discussion between Stephen Darwall and Michael Tomassello, we propose an alternative evolutionary account of moral motivation in its two-pronged dimension. We argue that an evolutionary account of moral motivation must account for the two forms of moral motivation that we distinguish: motivation to be partial, which is triggered by the affective relationships we develop with others; and motivation to be impartial, which is triggered by those norms to which we give impartial validity. To that aim, we present (...) the second-person standpoint of morality, first as Darwall conceives of it, and then as we reinterpret it from a naturalistic approach. Then we synthesize Tomasello’s evolutionary account of morality, and Darwall’s objections to it. To reply to those objections, building on Tomasello’s proposal, we argue that the motivation to be impartial, and the feeling of obligation to comply with normative requirements, appeared when humans anticipated and, critically, internalized others’ sanctions to the violation of social norms. Consequently, we posit that social norms and sanctions appeared first at the community level, and only after that were they internalized in the form of self-directed reactive attitudes. Finally, we derive some corollaries that follow from our proposal. (shrink)
