The Genetic Algorithm (GA) and Simulated Annealing (SA), two techniques for global optimization, were applied to a reduced (simplified) form of the phase problem (RPP) in computational crystallography. Results were compared with those of "enhanced pair flipping" (EPF), a more elaborate problem-specific algorithm incorporating local and global searches. Not surprisingly, EPF did better than the GA or SA approaches, but the existence of GA and SA techniques more advanced than those used in this study suggest that these techniques still hold (...) promise for phase problem applications. The RPP is, furthermore, an excellent test problem for such global optimization methods. (shrink)

A startling look at one of this century's most influential philosophers, the book chronicles every stage of Foucault's personal and professional odyssey, from his early interest in dreams to his final preoccupation with sexuality and the nature of personal identity.

Many people think that the amount of evil and suffering we observe provides important and perhaps decisive evidence against the claim that a loving God created our world. Yet almost nobody worries about the ethics of human procreation. Can these attitudes be consistently maintained? This chapter argues that the most obvious attempts to justify a positive answer fail. The upshot is not that procreation is impermissible, but rather that we should either revise our beliefs about the severity of global arguments (...) from evil or develop new and better defenses of human procreation. Although both possibilities are worthy of pursuit, this chapter focuses on the latter possibility. (shrink)

Presenting portraits of many central figures in modern physics, including Stephen Hawking and Leonard Susskind, this critique of modern theoretical physics provides the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy.

As a relatively young profession, public relations seeks a realistic ethics foundation. A continuing debate in public relations has pitted journalistic/objectivity ethics against the advocacy ethics that may be more appropriate in an adversarial society. As the journalistic/objectivity influence has waned, the debate has evolved, pitting the advocacy/adversarial foundation against the two-way symmetrical model of public relations, which seeks to build consensus and holds that an organization itself, not an opposing public, sometimes may need to change to build a productive (...) relationship. A similar battle between adversarial advocacy and symmetry occurred during the emergence of rhetoric in the Athens of the 4th century B.C. Plato and Aristotle favored adversarial/advocacy rhetoric, whereas Isocrates favored a symmetrical rhetoric. Four criteria of comparison of those rhetorics are examined: success of the respective schools, success of the respective graduates, the evaluation of later Roman rhetoricians, and the impact on the future of education. History shows that Isocrates's symmetrical rhetoric clearly was more effective than its adversarial/advocacy rivals. Recent studies of the two-way symmetrical model concur, indicating that it may well be the most effective foundation for public relations ethics. (shrink)

Freud's account of dreams has a cogent interpretive basis.

This article argues for a task-based approach to identifying and individuating cognitive systems. The agent-based extended cognition approach faces a problem of cognitive bloat and has difficulty accommodating both sub-individual cognitive systems ("scaling down") and some supra-individual cognitive systems ("scaling up"). The standard distributed cognition approach can accommodate a wider variety of supra-individual systems but likewise has difficulties with sub-individual systems and faces the problem of cognitive bloat. We develop a task-based variant of distributed cognition designed to scale up and (...) down smoothly while providing a principled means of avoiding cognitive bloat. The advantages of the task-based approach are illustrated by means of two parallel case studies: re-representation in the human visual system and in a biomedical engineering laboratory. (shrink)

The spiritual rewards and intellectual challenges of Eastern philosophy are revealed in this visually stunning book, illustrated by Joe Lee and with 19th-century engravings. Eastern philosophy is not only an intellectual pursuit, but one that involves one’s entire being. Much of it is so deeply entwined with the non-intellectual art of meditation, that the two are impossible to separate. In this survey of the major philosophies of India, China, Tibet and Japan, Jim Powell draws upon his knowledge of Sanskrit and (...) Chinese, as well as decades of meditation. Whether tackling Buddha, Confucius, Lao Tzu, Dogen, the Dalai Lama or Patanjal–Powell’s insights are deeply illuminating. All the major philosophies of India, China, Tibet and Japan are explained and everyone, from beginner to expert, will find Eastern Philosophy For Beginners an insightful overview. (shrink)

Using Jim Woodward's Counterfactual Dependency account as an example, I argue that causal claims about indeterministic systems cannot be satisfactorily analysed as including counterfactual conditionals among their truth conditions because the counterfactuals such accounts must appeal to need not have truth values. Where this happens, counterfactual analyses transform true causal claims into expressions which are not true.

Modern physics describes the mechanics of the Universe. We have discovered a new foundation for physics, which explains the components of the Universe with precision and depth. We quantify the existence of Aether, subatomic particles, and the force laws. Some aspects of the theory derive from the Standard Model, but much is unique. A key discovery from this new foundation is a mathematically correct Unified Force Theory. Other fundamental discoveries follow, including the origin of the fine structure constant and subatomic (...) particle g-factors, a slight correction of neutron magnetic moment, a geometrical structure for charge, the quantification of electromagnetic charge as separate from electrostatic charge, a more precise meaning of spin, the quantification of space-resonance in five dimensions, and a new system of quantum units. The Aether quantifies as a fabric of quantum rotating magnetic fields with electromagnetic, electrostatic, and gravitational dipole structures. Subatomic particles quantify as angular momentum encapsulated in a quantum, rotating magnetic field. All quantum, atomic, and molecular processes can be precisely modeled, leading to discrete physics with new understandings and insights. (shrink)

l examine the degree to which the so-called “deep ecology” movement embodies a feminist sensibility. In part one I take a brief look at the ambivalent attitude of “eco-feminism” toward deep ecology. In part two I show that this ambivalence sterns largely from the fact that deep ecology assimilates feminist insights to a basically masculine ethical orientation. In part three I discuss some of the ways in which deepecology theory might change if it adopted a fundamentally feminist ethical orientation.

In response to Hoeltje I concede the main point of his first section: for each logical truth S of the object language, it is a logical consequence of the Davidsonian theory of meaning I offered in my paper that S is logically true, contrary to what I asserted in the paper. However, I now argue that a Davidsonian theory of meaning may be formulated equally well in such a way that it not a logical consequence of the theory that S (...) is a logical truth. Nonetheless, the revised theory of meaning will still ‘entail’ in a wider sense that S is a logical truth, for we can prove by induction on the consequence class of the revised theory that S is a logical truth. So far, my disagreement with Hoeltje is over the more charitable interpretation of a passage from Davidson. I close by arguing that Davidson was mistaken on one point, a theory of meaning will entail a threefold distinction among the sentences of the object language, not a twofold distinction as he claimed.

This highly original book calls for, and suggests, a new way of considering war and warfare.

When we start with the wrong question, no matter how good an answer we get, it won’t give us the results we want. Rather than joining the throngs who are asking, When will this economic crisis be over? Jim Wallis says the right question to ask is How will this crisis change us? The worst thing we can do now, Wallis tells us, is to go back to normal. Normal is what got us into this situation. We need a new (...) normal, and this economic crisis is an invitation to discover what that means. Some of the principles Wallis unpacks for our new normal are . . . • Spending money we don’t have for things we don’t need is a bad foundation for an economy or a family. • It’s time to stop keeping up with the Joneses and start making sure the Joneses are okay. • The values of commercials and billboards are not the things we want to teach our children. • Care for the poor is not just a moral duty but is critical for the common good. • A healthy society is a balanced society in which markets, the government, and our communities all play a role. • The operating principle of God’s economy says that there is enough if we share it. • And much, much more . . . In the pages of this book, Wallis provides us with a moral compass for this new economy—one that will guide us on Wall Street, Main Street, and Your Street. Embracing a New Economy Getting back to "the way things were" is not an option. It is time we take our economic uncertainty and use it to find some moral clarity. Too often we have been ruled by the maxims that greed is good, it’s all about me, and I want it now. Those can be challenged only with some of our oldest and best values—enough is enough, we are in it together, and thinking not just for tomorrow but for future generations. Jim Wallis shows that the solution to our problems will be found only as individuals, families, friends, churches, mosques, synagogues, and entire communities wrestle with the question of values together.

Standard philosophical discussions of theory-ladeness assume that observational evidence consists of perceptual outputs (or reports of such outputs) that are sentential or propositional in structure. Theory-ladeness is conceptualized as having to do with logical or semantical relationships between such outputs or reports and background theories held by observers. Using the recent debate between Fodor and Churchland as a point of departure, we propose an alternative picture in which much of what serves as evidence in science is not perceptual outputs or (...) reports of such outputs and is not sentential in structure.

After Ontotheology: Reciprocal, Caring, Creative, and Right Relationships With the end of ontotheology we may realize, as Dewey did, that what sustains us is our caring relationships with physical nature, biological life, and other persons. My paper argues that relationships are ontologically basic and caring relations are morally basic. Right relationship binds us to the world and holds us together. We live by the grace of others. I conclude that after ontotheology, we must seek to form reciprocal, caring, and creative (...) relationships. (shrink)

Art and its Objects by Richard Wollheim had a major impact on aesthetics and the philosophy of art when it was first published in 1968. Of the arguments offered in response to Wollheim’s essay, Jerrold Levinson’s intentional-historical theory of art has been one of the most enduring. Levinson was influenced by three key sections of Wollheim’s enquiry: Section 40, which considers the claim that works of art fall under a concept of art, or that we are disposed to regard certain (...) things as works of art; and Sections 60 and 61, which deal with art as a historical phenomenon, and problems arising from its identification and interpretation. To date, these claims have been raised as points of contention in the philosophy of art. This paper takes a different perspective. Wollheim’s understanding of art’s historicity draws explicitly on the literature of theoretical art history. Via Wollheim, old art-historical problems will reappear as new philosophical questions.

Some biological processes move from step to step in a way that cannot be completely understood solely in terms of causes and correlations. This paper develops a notion of mechanistic information that can be used to explain the continuities of such processes. We compare them to processes that do not involve information. We compare our conception of mechanistic information to some familiar notions including Crick’s idea of genetic information, Shannon-Weaver information, and Millikan’s biosemantic information.

Background: There is general consensus internationally that unfair distribution of the benefits of research is exploitative and should be avoided or reduced. However, what constitutes fair benefits, and the exact nature of the benefits and their mode of provision can be strongly contested. Empirical studies have the potential to contribute viewpoints and experiences to debates and guidelines, but few have been conducted. We conducted a study to support the development of guidelines on benefits and payments for studies conducted by the (...) KEMRI-Wellcome Trust programme in Kilifi, Kenya. Methods: Following an initial broad based survey of cash, health services and other items being offered during research by all programme studies (n = 38 studies), interviews were held with research managers (n = 9), and with research staff involved in 8 purposively selected case studies (n = 30 interviewees). Interviews explored how these ‘benefits’ were selected and communicated, experiences with their administration, and recommendations for future guidelines. Data fed into a consultative workshop attended by 48 research staff and health managers, which was facilitated by an external ethicist.FindingsThe most commonly provided benefits were medical care (for example free care, and strengthened quality of care), and lunch or snacks. Most cash given to participants was reimbursement of transport costs (for example to meet appointments or facilitate use of services when unexpectedly sick), but these payments were often described by research participants as benefits. Challenges included: tensions within households and communities resulting from lack of clarity and agreement on who is eligible for benefits; suspicion regarding motivation for their provision; and confusion caused by differences between studies in types and levels of benefits. Conclusions: Research staff differed in their views on how benefits should be approached. Echoing elements of international benefit sharing and ancillary care debates, some research staff saw research as based on goodwill and partnership, and aimed to avoid costs to participants and a commercial relationship; while others sought to maximise participant benefits given the relative wealth of the institution and the multiple community needs. An emerging middle position was to strengthen collateral or indirect medical benefits to communities through collaborations with the Ministry of Health to support sustainability. (shrink)

In the last decade there has been an upsurge in the popularity of electric mountain bikes. However, opinion is divided regarding the implications of this emerging technology. Critics warn of the dangers they pose to landscapes, habitats, and ecological diversity, whilst advocates highlight their potential in increasing the accessibility of the outdoors for riders who would otherwise be socially and/or physically excluded. Drawing on interview data with 30 electric mountain bike users in England, this paper represents one of the first (...) attempts to empirically explore the experiential, ecological and socio-cultural implications of this activity. Utilising Stiegler’s (2013a) account of the pharmakon, in which technology is positioned as both remedy and poison, we suggest that the e-mountain bike’s role in the promotion of social and environmental responsibility is both complex and contradictory. Specifically, findings indicate that while this assistive technology can play a key role in facilitating deeper connections between riders as well as an ethic of care towards others, it can, at the same time, generate more individualised and automated experiences of recreational mobility in outdoor environments.

We report an experiment investigating the “special-process” theory of insight problem solving, which claims that insight arises from non-conscious, non-reportable processes that enable problem re-structuring. We predicted that reducing opportunities for speech-based processing during insight problem solving should permit special processes to function more effectively and gain conscious awareness, thereby facilitating insight. We distracted speech-based processing by using either articulatory suppression or irrelevant speech, with findings for these conditions supporting the predicted insight facilitation effect relative to silent working or thinking (...) aloud. The latter condition was included to investigate the currently contested effect of “verbal overshadowing” on insight, whereby thinking aloud is claimed to hinder the operation of special, non-reportable processes. Whilst verbal overshadowing was not evident in final solution rates, there was nevertheless support for verbal overshadowing up to and beyond.. (shrink)

Deep ecologists have criticized reform environmentalists for not being sufficiently radical in their attempts to curb human exploitation of the nonhuman world. Ecofeminists, however, maintain that deep ecologists, too, are not sufficiently radical, for they have neglected the cmcial role played by patriarchalism in shaping the cultural categories responsible for Western humanity’s domination of Nature. According to eco-feminists, only by replacing those categories-including atomism, hierarchalism, dualism, and androcentrism - can humanity learn to dweIl in harmony with nonhuman beings. After reviewing (...) the eco-feminist critique both of reform environmentalism and of deep ecology, I sketch a critical dialogue between eco-feminism and deep ecology. (shrink)

This paper presents a counterfactual account of what a mechanism is. Mechanisms consist of parts, the behavior of which conforms to generalizations that are invariant under interventions, and which are modular in the sense that it is possible in principle to change the behavior of one part independently of the others. Each of these features can be captured by the truth of certain counterfactuals.

Recent developments in ethics and postmodemist epistemology have set the stage for a reconceptualization of environmental ethics. In this paper, I sketch a path for postmodemism which makes use of certain notions current in contemporary environmentalism. At the center of my thought is the idea of place: place as the context of our lives and the setting in which ethical deliberation takes place; and the epistemological function of place in the construction of our understandings of self, community, and world. Central (...) to these themes, in tum, are the related notions of myth, narrative, storied residence, and ethical vernacular. (shrink)

The author looks at the continuing debate about the meaning of quantum theory. The historical development of the theory is traced from the turn of the century through to the 1930's, and the famous debate between Niels Bohr and Albert Einstein.

Recent research has begun treating the perennial philosophical question, “what makes a person the same over time?” as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, following Strohminger & Nichols (2014), has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity. While there is a growing body of evidence supporting these findings, a critique by (...) Starmans & Bloom (2018) suggests that this research program conflates personal identity with mere similarity. To address this criticism, we explore how loss of someone’s morality or memories influence perceptions of identity change, and perceptions of moral duties towards the target of the change. We present participants with a classic ‘body switch’ thought experiment and after assessing perceptions of identity persistence, we present a moral dilemma, asking participants to imagine that one of the patients must die (Study 1) or be left alone in a care home for the rest of their life (Study 2). Our results highlight the importance of the continuity of moral character, suggesting lay intuitions are tracking (something like) personal identity, not just mere similarity. (shrink)

The conclusion of this paper will be that e-sports are not sports. I begin by offering a stipulation and a definition. I stipulate that what I have in mind, when thinking about the concept of sport, is ‘Olympic’ sport. And I define an Olympic Sport as an institutionalised, rule-governed contest of human physical skill. The justification for the stipulation lies partly in that it is uncontroversial. Whatever else people might think of as sport, no-one denies that Olympic Sport is sport. (...) This seeks to ensure that those who might wish to dispute my conclusion might stay with the argument at least for as long as possible. Secondly, the justification for the stipulation lies partly in its normativity—I have chosen an Olympic conception of sport just because it seems to me to offer some kind of desirable version of what sport is and might become. Thirdly, I give examples which show how prominent promoters of e-sports agree with my stipulation, as evidenced by their strenuous attempts to comply with it i... (shrink)

Familiar versions of empiricism overemphasize and misconstrue the importance of perceptual experience. I discuss their main shortcomings and sketch an alternative framework for thinking about how human sensory systems contribute to scientific knowledge.

Machamer, Darden, and Craver argue that causal explanations explain effects by describing the operations of the mechanisms which produce them. One of this paper’s aims is to take advantage of neglected resources of Mechanism to rethink the traditional idea that actual or counterfactual natural regularities are essential to the distinction between causal and non-causal co-occurrences, and that generalizations describing natural regularities are essential components of causal explanations. I think that causal productivity and regularity are by no means the same thing, (...) and that the Regularists are mistaken about the roles generalizations play in causal explanation. Humean, logical empiricist, and other Regularist accounts of causal explanation have had the unfortunate effect of distracting philosophers’ from important non-explanatory scientific uses of laws and lesser generalizations which purport to describe natural regularities. My second aim is to characterize some of these uses, illustrating them with examples from neuroscientific research. (shrink)

Ethical conduct is a maxim in scholarly research as well as scholarly endeavour generally. In the case of research involving humans, few if any question the necessity for ethics approval of procedures by ethics boards or committees. However, concerns have been raised about the appropriateness of ethics approval processes for social science research arguing that the orientation of ethics boards and committees to biomedical and experimental scientific research, institutional risk aversion, and other factors lead to over-protection of research participants and (...) overly restrictive processes that delay and sometimes prevent important social science research. This is particularly significant when social science research is required to respond to social, environmental, or health emergencies and in contract research projects for the reasons explained. This analysis of an ethics approval case study adds to increasing concerns that ethics approval processes can have perverse effects in the social sciences. While a single case study does not provide generalizable findings, in-depth analysis of a significant case can identify issues that need to be further explored. Recommendations offer pathways for facilitating social science research including in emergency situations in which timeliness is important and in collaborative approaches such as participatory action research, while maintaining high ethical standards.

Frege claims that the laws of logic are characterized by their “generality,” but it is hard to see how this could identify a special feature of those laws. I argue that we must understand this talk of generality in normative terms, but that what Frege says provides a normative demarcation of the logical laws only once we connect it with his thinking about truth and science. He means to be identifying the laws of logic as those that appear in every (...) one of the scientific systems whose construction is the ultimate aim of science, and in which all truths have a place. Though an account of logic in terms of scientific systems might seem hopelessly antiquated, I argue that it is not: a basically Fregean account of the nature of logic still looks quite promising.

This book is based on the assumption that "organic has lost its way". Paradoxically, it comes at a time when we witness the continuing of growth in organic food production and markets around the world. Yet, the book claims that organic has lost sight of its first or fundamental philosophical principles and ontological assumptions. The collection offers empirically grounded discussions that address the principles and fundamental assumptions of organic farming and marketing practices. The book draws attention to the core principles (...) of organic and offers different clearly articulated and well-defined conceptual frameworks that offer new insights into organic practices. Divided into five parts, the book presents new perspectives on enduring issues, examines standards and certification, gives insights into much-discussed and additional market and consumer issues, and reviews the interplay of organic and conventional farming. The book concludes with a framework for rethinking ethics in the organic movement and reflections on the positioning of organic ethics. (shrink)

Visual analogy is believed to be important in human problem solving. Yet, there are few computational models of visual analogy. In this paper, we present a preliminary computational model of visual analogy in problem solving. The model is instantiated in a computer program, called Galatea, which uses a language for representing and transferring visual information called Privlan. We describe how the computational model can account for a small slice of a cognitive-historical analysis of Maxwell’s reasoning about electromagnetism.
