f gravity is examined in the context of a five-dimensional Kaluza-Klein theory with degenerate metric. In this theory electromagnetism is described by two vector fields, and there is a reflection symmetry between them which unifies them with gravitation. For matter, it is shown how the Lagrangian may be any function and still generate the same equations of motion, provided that some simple conditions are satisfied. The field equations are derived, and it is found that f gravity is not consistent with (...) the reflection symmetry. (shrink)
A mirror world consisting of matter which interacts with ordinary matter via gravity and weakly via other forces has been considered, inter alia, as a model for dark matter. A discrete symmetry under the interchange of fields means that both sectors experience the same forces. Separately it has been shown that it is possible to unify gravitation and electromagnetism by using a degenerate metric in five dimensions; in this theory there are two possible representations of charge, and there is a (...) reflection symmetry between them which, along with a gauge-like invariance, achieves the unification. Here it is shown that mirror matter arises naturally out of the degenerate theory, and as a result a new means for measuring the Brans–Dicke constant is obtained. (shrink)
We provide a retrospective of 25 years of the International Conference on AI and Law, which was first held in 1987. Fifty papers have been selected from the thirteen conferences and each of them is described in a short subsection individually written by one of the 24 authors. These subsections attempt to place the paper discussed in the context of the development of AI and Law, while often offering some personal reactions and reflections. As a whole, the subsections build into (...) a history of the last quarter century of the field, and provide some insights into where it has come from, where it is now, and where it might go.

Subjects can know what their attitudes are and also their motivating reasons for those attitudes – for example, S can know that she believes that q and also that she believes that q for the reason that p. One attractive account of self-knowledge of attitudes appeals to the ‘transparency method’. According to TM, subjects answer the question of whether they believe that q by answering the world-directed question of whether q is true. Something similar also looks intuitive in the case (...) of self-knowledge of motivating reasons, but cashing out such a view requires determining what the relevant world-directed question would be. This paper argues that subjects learn why they believe that q by answering the world-directed question ‘what are good reasons for believing that q?’ I argue for this against an alternative that I develop from Boyle 2011a.

Scale is a contested concept in human geography fostering debates and contestation that have escalated to the point where some have argued for the term to be expunged from the geographical lexicon. Yet, despite the importance of scale in the geography of religion, the scalar debates in human geography have only rarely penetrated the conceptual base of the sub-discipline. This article addresses the scale debate through a case study of adherents in three churches in West Virginia, USA. The study explores (...) these highly theoretical scalar issues through an empirical analysis of adherents, congregations and denominational leaders. A critical realist framework of emergence is used to demonstrate the value of a stratified, non-reductionist approach to the geography of religion. An emergent geography of religion is considered alongside other forms of religious social analysis such as poststructural ‘crossings and dwellings’ and actor network theory, and the role of critical realism in the broader scale debates in geography is evaluated.

Unethical behavior coordinated and concealed by teams continues to represent a troubling and all-too-frequent occurrence in organizations. Unfortunately, those who are most knowledgeable about this behavior and thereby best suited to report it to authorities—the complicit members themselves—are susceptible to unique pressures that often discourage them from blowing the whistle. Team members rely on their teammates for relational and other beneficial resources, making it more difficult to potentially break those ties by snitching. However, we argue that the pressure to stay (...) silent is alleviated for members who are ostracized by their team members. Drawing on social exchange theory, we theorize that ostracism decreases positive affect and increases negative affect, decreasing individuals’ communion striving motivation and, in turn, increasing the propensity to blow the whistle. In Study 1, we examined the link between ostracism and whistleblowing utilizing a field sample of diverse employees surveyed over time. In Study 2, we built upon Study 1 and conducted a lab study to examine affect and communion striving motivation as serial mediators. Results were generally supportive of our arguments, although we did not find support for the mediating effect of negative affect. (shrink)
This paper examines three forest value orientations – clusters of interrelated values and basic beliefs about forests – that emerged from an analysis of the public discourse about forest planning, management, and policy in the United States. The value orientations include anthropocentric, biocentric, and moral/spiritual/aesthetic orientations toward forests. Computer coded content analysis was used to identify shifts in the relative importance of these value orientations over the period 1980 through 2001. The share of expressions of anthropocentric forest value orientations declined (...) over this period, while the share of biocentric value expressions increased. Mora/spiritual/aesthetic value expressions remained constant over time. The observed shifts in forest value orientations have implications for identifying appropriate goals for public forest management and policy, developing socially acceptable means for accomplishing those goals, and dealing with inevitable conflict over forest management.

This short book is a history of what might be called the Chicago school of pragmatist evolutionary ethics. It places John Dewey and Jane Addams in their late-nineteenth-century intellectual context, emphasizing in particular how they drew on the work of Herbert Spencer, Thomas Henry Huxley, and Peter Kropotkin. Eddy suggests in her introduction that because today’s “social climate” is similar in many respects to that of the United States circa 1900, pragmatism may offer “significant insights for our situation now” (p. (...) xi). Her overall thesis is that although the ethical approach of Dewey and Addams was sometimes marred by a commitment to “teleological progress” (p. 38), at its best it defended a “melioristic hope” (p. 119): we try to make the world better, but there are no guarantees. Although the book provides some helpful context for the ethical work of the Chicago pragmatists, Eddy does not convincingly show that Addams and Dewey ever saw progress as “teleological,” in the sense of inevitable movement toward a specific end.

In the business world, one of the key challenges is how to survive in ever changing business environments and outperforming the competitors, while keeping the operational cost at minimum and profits at maximum level. In other words, this can be described as the problem of improving operational efficiency and reducing cost. Over the past few years due to global financial challenges, it has become even more important to improve the operational efficiency and reduce costs to survive through these tough conditions. (...) Like other successful implementations of Lean philosophy, especially in automobile, aerospace, steel and healthcare, it can be applied in cable manufacturing to achieve competitive, sustainable and profitable processes. The main focus of Lean philosophy is to create value for the stakeholders and end customers by reducing the non-value added activities or waste, and laying a strong foundation towards sustainable growth, by focusing on continuous process improvement. The overall philosophy provides a focused approach for continuous process improvement and the targeting of a variety of tools and methods to bring improvements. This paper presents case studies for Lean scheduling of manufacturing processes and exemplify how Lean scheduling processes allow organisations to maintain the continuous improvement philosophy. This paper also addresses the key elements of rescheduling processes i.e. how to schedule and when to schedule. Further, the paper will exemplify key benefits of Lean scheduling and how the Cable industry could benefit from the proposed approach. (shrink)
Despite its importance both historically and within the Aristotelian corpus, and despite the outpouring of first-rate scholarship on Aristotle in the past thirty years, the Politics has received much less attention than it deserves. This situation is, however, beginning to be rectified. The magisterial four-volume nineteenth-century commentary by W. L. Newman has been joined in recent years by numerous new translations as well as commentaries by Richard Robinson with supplementary material by David Keyt on Politics III-IV, Trevor Saunders on (...) Politics I and II, P. Simpson on the whole of the Politics, and in German by E. Schütrumpf on Politics I-VI. Richard Kraut’s new translation of and commentary on Politics VII and VIII, which provides Aristotle’s account of the ideal city, is an extremely distinguished contribution to our understanding of the Politics.

This paper argues against the view that trolley cases are of little or no relevance to the ethics of automated vehicles. Four arguments for this view are outlined and rejected: the Not Going to Happen Argument, the Moral Difference Argument, the Impossible Deliberation Argument and the Wrong Question Argument. In making clear where these arguments go wrong, a positive account is developed of how trolley cases can inform the ethics of automated vehicles.
Suppose a driverless car encounters a scenario where harm to at least one person is unavoidable and a choice about how to distribute harms between different persons is required. How should the driverless car be programmed to behave in this situation? I call this the moral design problem. Santoni de Sio defends a legal-philosophical approach to this problem, which aims to bring us to a consensus on the moral design problem despite our disagreements about which moral principles provide the correct (...) account of justified harm. He then articulates an answer to the moral design problem based on the legal doctrine of necessity. In this paper, I argue that Santoni de Sio’s answer to the moral design problem does not achieve the aim of the legal-philosophical approach. This is because his answer relies on moral principles which, at least, utilitarians have reason to reject. I then articulate an alternative reading of the doctrine of necessity, and construct a partial answer to the moral design problem based on this. I argue that utilitarians, contractualists and deontologists can agree on this partial answer, even if they disagree about which moral principles offer the correct account of justified harm. (shrink)
This paper first argues that we can bring out a tension between the following three popular doctrines: (i) the canonical reduction of metaphysical modality to essence, due to Fine, (ii) contingentism, which says that possibly something could have failed to be something, and (iii) the doctrine that metaphysical modality obeys the modal logic S5. After presenting two such arguments (one from the theorems of S4 and another from the theorems of B), I turn to exploring various conclusions we might draw (...) in light of these results, and argue that none comes cost free. In the course of laying out possible responses to my arguments, we'll have a chance to evaluate various doctrines about the interplay between contingency and essence, as well as develop some alternative reductions of metaphysical modality to essence. I don't decisively come down in favor of one response over the others, though I say some things that point towards the conclusion that essence has no role to play in reducing metaphysical modality.

ABSTRACTThis paper argues that confabulation is motivated by the desire to have fulfilled a rational obligation to knowledgeably explain our attitudes by reference to motivating reasons. This account better explains confabulation than alternatives. My conclusion impacts two discussions. Primarily, it tells us something about confabulation – how it is brought about, which engenders lively debate in and of itself. A further upshot concerns self-knowledge. Contrary to popular assumption, confabulation cases give us reason to think we have distinctive access to why (...) we have our attitudes. (shrink)
In both Metaphysics Γ 4 and 5 Aristotle argues that Protagoras is committed to the view that all contradictions are true. Yet Aristotle’s arguments are not transparent, and later, in Γ 6, he provides Protagoras with a way to escape contradictions. In this paper I try to understand Aristotle’s arguments. After examining a number of possible solutions, I conclude that the best way of explaining them is to (a) recognize that Aristotle is discussing a number of Protagorean opponents, and (b) (...) import another of Protagoras’ views, namely the claim that there are always two logoi opposed to one another.

Significant challenges arise for clinical care teams when a patient or surrogate decision-maker hopes a miracle will occur. This article answers the question, “How should clinical bioethicists respond when a medical decision-maker uses the hope for a miracle to orient her medical decisions?” We argue the ethicist must first understand the complexity of the miracle-invocation. To this end, we provide a taxonomy of miracle-invocations that assist the ethicist in analyzing the invocator's conceptions of God, community, and self. After the ethicist (...) appreciates how these concepts influence the invocator's worldview, she can begin responding to this hope with specific practices. We discuss these practices in detail and offer concrete recommendations for a justified response to the hope for a miracle. (shrink)
Environmental ethicists have not reached a consensus about whether or not individuals who contribute to climate change have a moral obligation to reduce their personal greenhouse gas emissions. In this paper, I side with those who think that such individuals do have such an obligation by appealing to the concept of integrity. I argue that adopting a political commitment to work toward a collective solution to climate change—a commitment we all ought to share—requires also adopting a personal commitment to reduce (...) one’s emissions. On these grounds, individuals who contribute to climate change have a prima facie moral duty to lower their personal greenhouse gas emissions. After presenting this argument and supporting each of its premises, I defend it from two major lines of objection: skepticism about integrity’s status as a virtue and concerns that the resulting moral duty would be too demanding to be morally required. I then consider the role that an appeal to integrity could play in galvanizing the American public to take personal and political action regarding climate change. (shrink)
