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.

Derrida is one of those annoying geniuses you can take a class on, read half-a-dozen books by and still have no idea what he’s talking about. Derrida’s ‘writing’ is definitely confusing (it’s like he’s pulling the rug out from under the rug that he pulled out from under philosophy). But beneath the confusion, like the heartbeat of a bird in your hand, you can feel Derrida’s electric genius. It draws you to it; you want to understand it…but it’s so confusing. (...) Jim Powell’s Derrida For Beginners is the clearest explanation of Derrida and deconstruction presently available in our solar system. Powell guides us through blindingly obscure texts like Grammatology (Derrida’s deconstruction of Saussure, Le;vi Strauss, Roussseau), “Diffe;rance” (his essay on language and life), Dissemination (his dismantling of Plato, his rap on Mallarme;), along with his other masterpieces.

The electronic and muonic hydrogen energy levels are calculated very accurately [1] in Quantum Electrodynamics (QED) by coupling the Dirac Equation four vector (c ,mc2) current covariantly with the external electromagnetic (EM) field four vector in QED’s Interactive Representation (IR). The c -Non Exclusion Principle(c -NEP) states that, if one accepts c as the electron/muon velocity operator because of the very accurate hydrogen energy levels calculated, the one must also accept the resulting electron/muon internal spatial and time coordinate operators (ISaTCO) (...) derived directly from c without any assumptions. This paper does not change any of the accurate QED calculations of hydrogen’s energy levels, given the simplistic model of the proton used in these calculations [1]. The Proton Radius Puzzle [2, 3] may indicate that new physics is necessary beyond the Standard Model (SM), and this paper describes the bizarre, and very different, situation when the electron and muon are located “inside” the spatially extended proton with their Centers of Charge (CoCs) orbiting the proton at the speed of light in S energy states. The electron/muon center of charge (CoC) is a structureless point that vibrates rapidly in its inseparable, non-random vacuum whose geometry and time structure are defined by the electron/muon ISaTCO discrete geometry. The electron/muon self mass becomes finite in a natural way due to the ISaTCOs cutting off high virtual photon energies in the photon propagator. The Dirac-Maxwell-Wilson (DMW) Equations are derived from the ISaTCO for the EM fields of an electron/muon, and the electron/muon “look” like point particles in far field scattering experiments in the same way the electric field from a sphere with evenly distributed charge “e” “looks” like a point with the same charge in the far field (Gauss Law). The electron’s/muon’s three fluctuating CoC internal spatial coordinate operators have eight possible eigenvalues [4, 5, 6] that fall on a spherical shell centered on the electron’s CoM with radius in the rest frame. The electron/muon internal time operator is discrete, describes the rapid virtual electron/positron pair production and annihilation. The ISaTCO together create a current that produce spin and magnetic moment operators, and the electron and muon no longer have “intrinsic” properties since the ISaTCO kinematics define spin and magnetic moment properties.

In 1939, just before graduating from high school in the small town of Ridgeway in northeast Iowa, Everett Kuntz spent his entire savings of $12.50 on a 35mm Argus AF camera. He made a camera case from a worn-out boot, scraps from a tin can, and a clasp from his mother’s purse. For the next several years, especially during the summers when he worked on his parents’ dairy farm, he clicked the shutter of his trusty Argus all around the quiet (...) town. Everett bought movie reel film in bulk from a mail-order house, rolled his own film, and developed it in a closet at home, but he never had the money to print his photographs. More than two thousand negatives stayed in a box while he married, raised a family, and worked as an electrical engineer in the Twin Cities. When he became ill with cancer in the fall of 2002—sixty years after he had developed the last of his bulk film—Everett opened his time capsule and printed the images from his youth. He died in 2003, having brought his childhood town back to life just as he was leaving it. A sense of peace radiates from these images. Whether skinny-dipping in the Turkey River, wheelbarrow-racing, threshing oats, milking cows, visiting with relatives after church, or hanging out at the drugstore or the movies, Ridgeway’s hardworking citizens are modest and trusting and luminous in their graceful harmony and their unguarded affection for each other. Visiting the town in 2006 as he was writing the text to accompany these photographs, Jim Heynen crafted vignettes that perfectly complement these rediscovered images by blending fact and fiction to give context and voice to Ridgeway’s citizens.

About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could (...) further improve the identification of eloquent cortex. We compared gamma, alpha and beta activity, and their combinations for the identification of eloquent cortical areas defined by ESM. Ten patients with intractable focal epilepsy participated in a delayed-match-to-sample task, where syllable sounds were compared to visually presented letters. We used a generalized linear model approach to find the optimal weighting of each band for predicting ESM-defined categories and estimated the diagnostic ability by calculating the area under the receiver operating characteristic curve. Gamma activity increased more in eloquent than in non-eloquent areas, whereas alpha and beta power decreased more in eloquent areas. Diagnostic ability of each band was close to 0.7 for all bands but depended on multiple factors including the time period of the cognitive task, the location of the electrodes and the patient’s degree of attention to the stimulus. We show that diagnostic ability can be increased by 3–5% by combining gamma and alpha and by 7.5–11% when gamma and beta were combined. We then show how ECoG power modulation from cognitive testing can be used to map the probability of eloquence in individual patients and how this probability map can be used in clinical settings to optimize ESM planning. We conclude that the combination of gamma and beta power modulation during cognitive testing can contribute to the identification of eloquent areas prior to ESM in patients with refractory focal epilepsy.

Managing aggression in mental health hospitals is an important and challenging task for clinical nursing staff. A majority of studies focus on the perspective of clinicians, and research mainly depicts aggression by referring to patient-related factors. This qualitative study investigates how aggression is communicated in forensic mental health nursing records. The aim of the study was to gain insight into the discursive practices used by forensic mental health nursing staff when they record observed aggressive incidents. Textual accounts were extracted from (...) the Staff Observation Aggression Scale-Revised (SOAS-R), and Fairclough’s Critical Discourse Analysis was used to identify short narrative entries depicting patients and staffs in typical ways. The narratives contained descriptions of complex interactions between patient and staff that were linked to specific circumstances surrounding the patient. These antecedents, combined with the aggression incident itself, created stereotyping representations of forensic psychiatric patients as deviant, unpredictable and dangerous. Patient and staff identities were continually (re)produced by an automatic response from the staff that was solely focused on the patient’s behavior. Such response might impede implementation of new strategies for managing aggression. (shrink)

The introduction of contraceptive technologies hasresulted in the separation of sex and procreation. Theintroduction of new reproductive technologies (mainlyIVF and embryo transfer) has led not only to theseparation of procreation and sex, but also to there-definition of the terms mother and family.For the purpose of this essay, I will distinguishbetween:1. the genetic mother – the donor of the egg;2. the gestational mother – she who bears and gives birth to the baby;3. the social mother – the woman who raises the (...) child.This essay will deal only with the form of gestationalsurrogacy in which the genetic parents intend to bethe social parents, and the surrogate mother has nogenetic relationship to the child she bears anddelivers. I will raise questions regarding medicalethical aspects of surrogacy and the obligation(s) ofthe physician(s) to the parties involved. I will arguethat the gestational surrogate is a womb to rent,that there is great similarity between gestationalcommercial surrogacy and organ transplant marketing.Furthermore, despite claims to freedom of choice andfree marketing, I will claim that gestationalsurrogacy is a form of prostitution and slavery,exploitation of the poor and needy by those who arebetter off. The right to be a parent, although notconstitutional, is intuitive and deeply rooted.However, the issue remains whether this rightoverrules all other rights, and at what price to theparties involved. I will finally raise the followingprovocative question to society: In the interim periodbetween today''s limited technology and tomorrow''sextra-corporeal gestation technology (ectogenesis),should utilizing females in PVS (persistent vehetativestate) for gestational surrogacy be sociallyacceptable/permissible – provided they have leftpermission in writing?

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)

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.

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.

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.

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.

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.

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.

Central (...) to these themes, in tum, are the related notions of myth, narrative, storied residence, and ethical vernacular. (shrink)

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)

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)

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.

Interpretation groups, which meet on a regular basis for jointly analysing qualitative data, are well-established in sociology and related disciplines. There are currently at least 71 interpretation groups in German-speaking countries, and there are more if one includes project teams, which meet on a regular basis for data sessions. Yet, there is relatively little knowledge based on empirical research about these groups and their practices. Inspired by studies on social sciences and humanities, this article examines how “good” interpretations are jointly (...) created in these groups. Prior studies underlined that social scientific methods are productive, i.e., performative. Following this lead, my study turns data analysis in qualitative research into an object of inquiry by investigating how interpretation groups work on textual data. More specifically, this article discusses how these groups negotiate different interpretative options and at the same time evaluate the quality of their results as well as the interpretation process as a whole. In this regard, the approach presented in this article also contributes to the growing literature on valuation and evaluation in science by focusing on communicative devices for valuing and evaluating interpretations.

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.

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.

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)

Why does Frege claim that logical axioms are ‘self‐evident,’ to be recognized as true ‘independently of other truths,’ and then offer arguments for those axioms? I argue that he thinks the arguments provide us with the justification that we need for accepting the axioms and that this is compatible with his remarks about self‐evidence. This compatibility depends on philosophical considerations connected with the ‘critical method’: an interesting approach to the justification of axioms endorsed by leading philosophers at the time.

Commentators regularly attribute to Frege realist, idealist, and quietist responses to metaphysical questions concerning the abstract objects he calls ‘thoughts’. But despite decades of effort, the evidence offered on behalf of these attributions remains unconvincing. I argue that Frege deliberately avoids commitment to any of these positions, as part of a metaphysical separatist policy motivated by the fact that logic is epistemologically autonomous from metaphysics. Frege’s views and arguments prove relevant to current attempts to argue for epistemological autonomy, particularly that (...) of ethics. (shrink)

As pervasive as the use of the Internet has become in the United States, a huge percentage of the world’s population has yet to ever use a telephone. It seems ironic, then, that there is a concerted effort on the part of industrialized nations to first hook up their traditionally disadvantaged citizens to the Internet and second, to hook up citizens of developing nations. This paper addresses the universal access phenomenon by considering the growth of the Internet in terms of (...) Leaver and Taker users—idioms usually associated with a culture’s interactions with its environment. Leaver cultures interact with their environment in a sustainable manner while Taker cultures produce more than they need and impose their ways upon others. The Internet is explored as a community of users, which in its current state is dominated by Takers. However, realizing the need for a more heterogeneous Internet community, this paper explores incentives for Leaver cultures to assimilate online and methods of improving interface designs to be more intuitive to Leaver communities. It is hoped that a tragedy of the commons of Internet resources can be avoided as more Leavers participate in the sustainment of the Internet as a valuable tool for all communities. (shrink)

"We become what we love," states Jim Garrison in Dewey and Eros: Wisdom and Desire in the Art of Teaching. This provocative book represents a major new interpretation of Dewey's education philosophy.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 10.2 (2005) 101-135 [Access article in PDF] Truth, Knowledge and the Wild World Jim Cheney One ought not to put too much stock in the word 'philosophy'.... [T]here are alternative ways of intelligently engaging the world. To construe one's thinking in terms of belief is characteristic of a particular kind of world view and it remains to be seen whether those who share an indigenous (...) world view conceive of experience in such an overtly intellectualized manner. Leroy N. Meyer and Tony Ramirez (1996, 104)1 Wilderness treats me like a human being. Tom Birch2As Holmes Rolston III has said, "A principal characteristic of human life is that it develops into biography. In that sense, humans do not want their values in nature, any more than they want other goods in life, to come seriatim, like beads on a string.... Humans want a storied residence in nature where the passage of time integrates past, present, and future in a meaningful career" (Rolston 1988, 351). This is what I had hoped for: a narrative of storied residence in Midwest prairie, lake, and river country, and in the mountains and deserts of Idaho, with the history of the development of an environmental ethic (or ethos) left largely implicit within that larger narrative, leaving readers to reflect as they may on the philosophical dimensions of the journey. To leave traditional philosophical [End Page 101] modes of expression completely behind proved impossible (for now), but it has been for me a worthwhile exercise to locate my reflections on "truth, knowledge, and the wild world" in something of a narrative form. It is the lakes and rivers, prairies, mountains, and deserts that have remained implicit. They have cast their spell, however, on any attempt to impose cultural order on the relationship between truth, knowledge, and the wild world. I Looking back on it, it seems that my entire philosophical career has been implicated—in one way or another, directly and indirectly—in these two questions: "How important is truth to knowledge and epistemology?" and "What is the role of natural environments in the production of knowledge?" Furthest back, at the very origin of my philosophical life, reflections on philosophical knowledge were inevitably posed and thought about in natural environments, particularly in my meditations as I drifted in the early morning mist on the St. Croix River and several Minnesota lakes, especially Cedar Lake. Even now, when I am trying to make my way to a new understanding of some philosophical issue, I walk along the shores of Lake Michigan and the Milwaukee River, or sit by rivers and lakes in Idaho, a place that became my second home after meeting my partner, Fran. Northern White Cedars stand in our yard, front and back; Western Red Cedar holds our house in its embrace.There is no question in my mind that natural environments are the deepest sources of whatever philosophical understandings I may have come to. In terms of formal studies, however, the question of the role of natural environments in the production of knowledge did not emerge for me until, well into my teaching career, I discovered the newly-emerging field of environmental ethics. It was at that point that the deepest wellspring of my philosophy and my life came together with my professional philosophical interests—in an uneasy balance. Until that time, as I think of it now, my philosophical track through the curious environment of the academy, however well it prepared me to think about central issues in environmental ethics, was mostly marked by a fascination with glittering baubles and gemstones and did not truly touch the soil, water, and atmosphere of my life.Questions of truth, knowledge, and epistemology took center stage from the beginning of my formal philosophical studies. As an undergraduate [End Page 102] at Berkeley, Thompson Clarke introduced me (in three courses) to the skeptical implications of Ordinary Language Philosophy that had escaped the attention of J. L. Austin and others. This baptism into the rigors of skeptical philosophy left me pretty much convinced, as my partner and... (shrink)

Feminist analysis has eonvineed me that certain tendencies within that form of radical environmentalism known as deep ecology-with its supposed rejection of the Western ethical tradition and its adoption of what looks to be a feminist attitude toward the environment and our relationship to nature-constitute one more chapter in the story of Western alienation from nature. In this paper I deepen my critique of these tendencies toward alienation within deep ecology by historicizing my critique in the light of a development (...) in the ancient world that is disquietingly similar to the rise of deep ceology in recent times-namely, the rise of Stoicism in the wake of the breakup of the ancient polis.

I offer an epistemologically grounded revisioning of Tom Birch’s ethical principle of universal consideration, suggesting that epistemologies have ethical dimensions and hence that universal moral consideration is intrinsic to the epistemological enterprise. I contrast epistemologies of domination with epistemologies in part constituted by the generosity of spirit that is the hallmark of Birch’s notion of universal consideration.
