The prevalence of optimality models in the literature of evolutionary biology is testimony to their popularity and importance. Evolutionary biologist R. C. Lewontin, whose criticisms of optimality models are considered here, reflects that "optimality arguments have become extremely popular in the last fifteen years, and at present represent the dominant mode of thought." Although optimality models have received little attention in the philosophical literature, these models are very interesting from a philosophical point of view. As will be argued, optimality models (...) are central to evolutionary thought, yet they are not readily accomodated by the traditional view of scientific theories. According to the traditional view, we would expect optimality models to employ general, empirical laws of nature, but they do not. Fortunately, the semantic view of scientific theories, a recent alternative to the traditional view, more readily accomodates optimality models. As we would expect on the semantic view, optimality models can be construed as specifications of ideal systems. These specifications may be used to describe empirical systems--that is, the specifications may have empirical instances. But the specifications are not empirical claims, much less general, empirical laws. Although philosophers have yet to discuss the general features and uses of optimality models, these topics have stimulated much recent discussion among evolutionary biologists. Their discussions raise a number of precautions concerning the proper use of optimality models. Moreover, many of their caveats can be interpreted as general reminders that 1) optimality models specify ideal systems whose empirical instantiations may be quite restricted, and that 2) optimality models should not be construed as general, empirical laws. As G. F. Oster and E. O. Wilson caution, "the prudent course is to regard optimality models as provisional guides to further empirical research and not necessarily as the key to deeper laws of nature." It seems, then, that the semantic view of theories is more sensitive to the nature and limitations of optimality models than is the more traditional view of theories. (shrink)

Much if not most recent literature in philosophy of biology concerns the extent to which biological theories conform to what is known as the "received" philosophical view of scientific theories, a descendant of the logical-empiricist view of theories. But the received view currently faces a competitor--a very different view of theories known as the "semantic" view. It is argued here that the semantic view is more sensitive to the nature and limitations of evolutionary theory than is the received view. In (...) particular, the semantic view better accomodates the fact that evolutionary theory is bound to change as a result of the evolutionary process itself. This unusual feature of evolutionary theory provides a good reason for reconsidering the received view and paying close attention to the semantic view. (shrink)

Zusammenfassung Zur ordnungsgemäßen Durchführbarkeit des Spielbetriebs setzen die deutschen Profisportligen Li­zenzierungsverfahren ein. Dabei stehen insbesondere zur Eindämmung der Rattenrennen-Proble­matik und zur Sicherstellung der finanziellen Stabilität der teilnehmenden Klubs und damit zum Vermeiden negativer Externalitäten die finanzwirtschaftlichen Anforderungen im Fokus. In den ver­gangenen Jahren kam es trotz dieser Vorkehrungen in den fünf größten deutschen Profisportligen im Basketball, Eishockey, Fußball, Handball sowie Volleyball mehrfach zu finanziellen Schieflagen. Vor dem Hintergrund wird in diesem Beitrag die finanzwirtschaftliche Lizenzierung der Profisport­ligen anhand von sechs Haupt- (...) und 62 Subkriterien strukturiert und umfassend analysiert. Ziel die­ser vergleichenden Untersuchung ist die Herausarbeitung von Gemeinsamkeiten und Unterschieden sowie die Ableitung von Stärken und Schwächen. Aus sportökonomischer Perspektive werden auf dieser Basis Verbesserungsmöglichkeiten der Lizenzierungsverfahren entwickelt. (shrink)

Microvascular development is determined by the interplay between tissue cells and microvascular endothelial cells. Because the pancreatic islet is an organ composed mainly of endothelial and endocrine cells, it represents a good model tissue for studying microvascular development in the context of a tissue. In this review, we will describe the special morphology of islet capillaries and its role in the physiologic function of islets: secretion of insulin in response to blood glucose levels. We will speculate on how islet‐secreted VEGF‐A (...) generates a permeable endothelium that allows insulin to pass quickly into the blood stream. In addition, we speculate on how endothelial cells might form a capillary lumen within the islets. At the end, we look at the islet microvasculature from a medical point of view, thus describing its critical role during type I diabetes and islet transplantation.

Current models of speech motor control rely on either trajectory-based control (DIVA, GEPPETO, ACT) or a dynamical systems approach based on feedback control (Task Dynamics, FACTS). While both approaches have provided insights into the speech motor system, it is difficult to connect these findings across models given the distinct theoretical and computational bases of the two approaches. We propose a new extension of the most widely used dynamical systems approach, Task Dynamics, that incorporates many of the strengths of trajectory-based approaches, (...) providing a way to bridge the theoretical divide between what have been two separate approaches to understanding speech motor control. The Task Dynamics (TD) model posits that speech gestures are governed by point attractor dynamics consistent with a critically damped harmonic oscillator. Kinematic trajectories associated with such gestures should therefore be consistent with a second-order dynamical system, possibly modified by blending with temporally overlapping gestures or altering oscillator parameters. This account of observed kinematics is powerful and theoretically appealing, but may be insufficient to account for deviations from predicted kinematics—i.e., changes produced in response to some external perturbations to the jaw, changes in control during acquisition and development, or effects of word/syllable frequency. Optimization, such as would be needed to minimize articulatory effort, is also incompatible with the current TD model, though the idea that the speech production systems economizes effort has a long history and, importantly, also plays a critical role in current theories of domain-general human motor control. To address these issues, we use Dynamic Movement Primitives (DMPs) to expand a dynamical systems framework for speech motor control to allow modification of kinematic trajectories by incorporating a simple, learnable forcing term into existing point attractor dynamics. We show that integration of DMPs with task-based point-attractor dynamics enhances the potential explanatory power of TD in a number of critical ways, including the ability to account for external forces in planning and optimizing both kinematic and dynamic movement costs. At the same time, this approach preserves the successes of Task Dynamics in handling multi-gesture planning and coordination. (shrink)

An internal critique of anthropology in recent decades has shifted the focus and scope of anthropological work on emotion. In this article I review the changes, explore the pros and cons of leading anthropological approaches and theories, and argue that—so far as anthropology is concerned—only detailed narrative accounts can do full justice to the complexity of emotions. A narrative approach captures both the particularity and the temporal dimension of emotion with greater fidelity than semantic, synchronic, and discourse-based approaches.

James Beattie was appointed professor of moral philosophy and logic at Marischal College, Aberdeen, Scotland at the age of twenty-five. Though more fond of poetry than philosophy, he became part of the Scottish 'Common Sense' school of philosophy that included Thomas Reid and George Campbell. In 1770 Beattie published the work for which he is best known, An Essay on Truth, an abrasive attack on 'modern scepticism' in general, and on David Hume in particular, subsequently and despite Beattie's attack, Scotland's (...) most famous philosopher. The Essay was a great success, earning its author an honorary degree from Oxford and an audience with George III. Samuel Johnson declared in 1772 that 'We all love Beattie'. Hume, on the other hand, described the Essay as 'a horrible large lie in octavo', and dismissed its author as a 'bigotted silly Fellow'. Although Beattie is no match for Hume as a philosopher, the success of the Essay suggests that, unlike Hume, Beattie voices the characteristic assumptions, and anxieties, of his age. The first part of this selection—the first ever made from Beattie's prose writings—includes several key chapters from the Essay on Truth, along with extracts from all of Beattie's other works on moral philosophy. The topics treated include memory, the existence of God, the nature of virtue, and slavery. The second part of the selection is devoted to Beattie's contributions to literary criticism and aesthetics. Beattie's studies of poetry, music, taste, and the sublime are vital to the understanding of the literary culture out of which developed the early Romanticism of Wordsworth and Coleridge. (shrink)

The concept of "fitness" is a notion of central importance to evolutionary theory. Yet the interpretation of this concept and its role in explanations of evolutionary phenomena have remained obscure. We provide a propensity interpretation of fitness, which we argue captures the intended reference of this term as it is used by evolutionary theorists. Using the propensity interpretation of fitness, we provide a Hempelian reconstruction of explanations of evolutionary phenomena, and we show why charges of circularity which have been levelled (...) against explanations in evolutionary theory are mistaken. Finally, we provide a definition of natural selection which follows from the propensity interpretation of fitness, and which handles all the types of selection discussed by biologists, thus improving on extant definitions.

Of all the scientists discussed by Mitman, Keller, and Taylor, Odum stands out most as the technocrat, the social engineer. But less obvious candidates, like Allee, also fancied themselves in this capacity: “Our task as biologists and as citizens of a civilized country, is a practical engineering job.” Allee had in mind the establishment of an international cooperative order based on his biological principles. He apparently did not recognize the extent to which his principles were themselves an engineering feat: he (...) had already constructed a world in which eternal peace and order were possible.To an engineer in the traditional sense, the world is changeable, but not in all respects; there are constraints, and these constraints are taken very seriously. Scientists acting as engineers, in the traditional sense, must also pay attention to constraints. But scientists sometimes also take the option of engineering the very constraints, intellectually reconstructing the world so that it can (supposedly) be physically manipulated in the desired direction. There seems to be a lot of engineering, in the extended sense, going on in the very interesting stories that Mitman, Keller, and Taylor tell. (shrink)

"Theoretical pluralism" obtains when there are good evidential reasons for accommodating multiple theories of the same domain. Issues of "relative significance" often arise in connection with the investigation of such domains. In this paper, I describe and give examples of theoretical pluralism and relative significance issues. Then I explain why theoretical pluralism so often obtains in biology--and why issues of relative significance arise--in terms of evolutionary contingencies and the paucity or lack of laws of biology. Finally, I turn from explanation (...) to justification, and raise questions about the purpose and value of concerns and disagreements about relative significance. (shrink)

Cet ouvrage prend pour objet les effets de la féminisation massive des activités équestres depuis l’après-guerre, tant au niveau statistique que du point de vue du contenu des pratiques.

Gender dysphoria is a clinically significant incongruence between expressed gender and assigned gender, with rapidly growing prevalence among children. The UK High Court recently conducted a judicial review regarding the service provision at a youth-focussed gender identity clinic in Tavistock. The high court adjudged it ‘highly unlikely’ that under-13s, and ‘doubtful’ that 14–15 years old, can be competent to consent to puberty blocker therapy for GD. They based their reasoning on the limited evidence regarding efficacy, the likelihood of progressing to (...) cross-sex hormone therapy and the ‘life-changing consequences’ of puberty blockers. In this article, I offer two concurrent arguments to dispute their reasoning. First, I argue that minors can be competent to consent to puberty blockers for GD, because the decision to undergo puberty blocker therapy is no more complex or far-reaching than other medical decisions that we accept a child should be able to make. Second, I argue that—irrespective of competence—such legal restriction for all children fundamentally contradicts the central ethical tenet of child healthcare: best interests. For these two reasons, the high court should not restrict access to puberty blockers for competent GD children. (shrink)

In “Spandrels,” Gould and Lewontin criticized what they took to be an all-too-common conviction, namely, that adaptation to current environments determines organic form. They stressed instead the importance of history. In this paper, we elaborate upon their concerns by appealing to other writings in which those issues are treated in greater detail. Gould and Lewontin’s combined emphasis on history was three-fold. First, evolution by natural selection does not start from scratch, but always refashions preexisting forms. Second, preexisting forms are refashioned (...) by the selection of whatever mutational variations happen to arise: the historical order of mutations needs to be taken into account. Third, the order of environments and selection pressures also needs to be taken into account. (shrink)

This is the second of a two-part essay on the history of debates concerning the creativity of natural selection, from Darwin through the evolutionary synthesis and up to the present. In the first part, I focussed on the mid-late nineteenth century to the early twentieth, with special emphasis on early Darwinism and its critics, the self-styled “mutationists.” The second part focuses on the evolutionary synthesis and some of its critics, especially the “neutralists” and “neo-mutationists.” Like Stephen Gould, I consider the (...) creativity of natural selection to be a key component of what has traditionally counted as “Darwinism.” I argue that the creativity of natural selection is best understood in terms of selection initiating evolutionary change, and selection directing evolutionary change, for example by creating the variation that it subsequently acts upon. I consider the respects in which both of these claims sound non-Darwinian, even though they have long been understood by supporters and critics alike to be virtually constitutive of Darwinism.

In this unconventional article, Sarah Banet-Weiser, Rosalind Gill and Catherine Rottenberg conduct a three-way ‘conversation’ in which they all take turns outlining how they understand the relationship among postfeminism, popular feminism and neoliberal feminism. It begins with a short introduction, and then Ros, Sarah and Catherine each define the term they have become associated with. This is followed by another round in which they discuss the overlaps, similarities and disjunctures among the terms, and the article ends with how (...) each one understands the current mediated feminist landscape.

Recently, we identified myeloid‐derived growth factor (MYDGF) as a blood flow‐induced angiocrine signal that promotes human and mouse hepatocyte proliferation and survival. Here, we review literature reporting changes in blood flow after partial organ resection in the liver, lung, and kidney, and we describe the angiocrine signals released by endothelial cells (ECs) upon blood flow alterations in these organs. While hepatocyte growth factor (HGF) and MYDGF are important angiocrine signals for liver regeneration, by now, angiocrine signals have also been reported (...) to stimulate hyperplasia and/or hypertrophy during the regeneration of lungs and kidneys. In addition, angiocrine signals play a critical role in tumor growth. Understanding the mechano‐elastic properties and flow‐mediated alterations in the organ‐specific microvasculature is crucial for therapeutic approaches to maintain organ health and initiate organ renewal.

Among the liveliest disputes in evolutionary biology today are disputes concerning the role of chance in evolution--more specifically, disputes concerning the relative evolutionary importance of natural selection vs. so-called "random drift". The following discussion is an attempt to sort out some of the broad issues involved in those disputes. In the first half of this paper, I try to explain the differences between evolution by natural selection and evolution by random drift. On some common construals of "natural selection", those two (...) modes of evolution are completely indistinguishable. Even on a proper construal of "natural selection", it is difficult to distinguish between the "improbable results of natural selection" and evolution by random drift. In the second half of this paper, I discuss the variety of positions taken by evolutionists with respect to the evolutionary importance of random drift vs. natural selection. I will then consider the variety of issues in question in terms of a conceptual distinction often used to describe the rise of probabilistic thinking in the sciences. I will argue, in particular, that what is going on here is not, as might appear at first sight, just another dispute about the desirability of "stochastic" vs. "deterministic" theories. Modern evolutionists do not argue so much about whether evolution is stochastic, but about how stochastic it is. (shrink)

What is it for history to matter? Stephen Gould argued that unpredictability is part of the answer. For example, the “fact“ that repeated replays of the history of life would end differently every time is a sign that history matters to the course of evolution. But there is a problem here: if a particular point in the past leaves open alternative possible futures, then in what sense does that point in the past matter with regard to which of the outcomes (...) occurs? We argue that unpredictability is central to the importance of history. However, it is not the unpredictability of the future, but rather the unpredictability of the past itself that is the key. History matters when a particular future depends on a particular past that was not bound to happen, but did. (shrink)

Publishers love titles that begin How or Why. Better still, How and Why, combining edification with utility. The target group is that overlap between the self-help audience and the idly curious—which is to say, most of us. And since emotions are very much about self-help and self-harm, they offer rich pickings in a burgeoning market. Flanagan's How to Do things with Emotions is a philosopher's take on moral emotions, the allusion to J. L. Austin's How to Do Things with Words (...) chiming with the self-help milieu. Reviewing cases, Flanagan points out that most scientific work in this field derives from experiments on psychology students, about as unrepresentative a slice of humanity as you could find. For Flanagan, they are too WEIRD (Western, Educated, Industrialized, Rich, Democratic) to tell us much about the non-weird majority. To learn to “do emotions better,” he argues, we have to look farther afield. Although the emotional lives of cultural others are surely different from those taking Psychology 101, at some functional level they might be similar. Work out the conceptual logic and practical rationale of culturally elaborated emotions—Minangkabau “shame,” Ifaluk “righteous anger,” American “road rage”—and there is scope for comparison. Indeed, anthropology has shown as much, and it is from anthropology that Flanagan takes his cues. To mention two famous cases, what can we learn about anger management from Utku igloo-dwellers and Ilongot headhunters? Mutually dependent for survival in their snowy isolation, the Utku cannot risk getting angry. (They mercilessly tease their children into learning the futility of anger.) In the jungles of Luzon, Ilongot youths cast away their anger in externally directed violence: headhunting as cathartic sport. We can think of parallels closer to home.Flanagan's vigorously argued book, a tour de force of its kind, is both an anatomizing of anger and shame—two moral emotions we tend to “do badly”—and a proposal to “change how we do these emotions.” Indignation is fine, but anger that is vengeful or “pain-passing,” rather than righteous, is irrational and socially harmful. Shame can be incapacitating and cruel (the undeserved burn of a Twitter pile-on). What we need is reflective anger directed at injustice and a “mature sense of shame” that reminds us of the social contract and stops us misbehaving.In its How-and-Why format, the book combines theory and practice, metaethics with moralism. Here is how a prof should do self-help. But if the diagnosis is well made, the remedy is hard to imagine. As Flanagan recognizes, moral sentiments and practices are embedded in intricate forms of life and not readily detachable. Anger Utku-style is not a transferable skill, nor are educative routines forged in social ecologies remote from our own. Lacking serviceable models, Flanagan falls back on the anthropological justification that knowledge of cultural diversity expands our sense of human possibility, of other roads taken. In a globalizing world, difference is its own reward. For me, an anthropologist, that maxim is enough. Yet difference bedevils comparison, jinxing the units, warping criteria. Most languages lack a word for emotion or an equivalent umbrella concept; nor do emotion words translate well across languages. Emotion may be an incoherent notion, or at best a heuristic.Flanagan's use of the WEIRD tag makes things a bit too easy. Does it cover farmhands and factory workers? Are we so democratic, anyway? More damagingly, a typological approach blurs the circumstances of family, community, and biography that define an emotional episode and shape its phenomenology, the way it is felt and experienced—what a violent outburst or fearful exit means in the context of a life. Take Joseph Conrad's Lord Jim, who flees a scene of failure and derails his life. It requires a long narrative to unravel the implications of his jumping ship and the paralyzing shame he experiences before the judgment of society. Or consider the scene in Anna Karenina in which the dignified and self-important Karenin, apprised of Anna's adulterous liaison, agonizes over the threat to his existence. To call his response jealousy would not scratch the surface. Characteristically for Tolstoy, the emotions go unnamed. Instead, we witness Karenin's fervid deliberations (emotions involve thoughts), vacillations (emotions have action tendencies), anguished calculations of impending scandal (emotions are appraisals), and bodily changes (emotions are cognized feelings). We shudder at the brutal metaphors through which he grasps his predicament and its cure: like rooting out a bad tooth, he decides. That welter of particularities escapes the theorist who needs clear-cut, comparable units, formulaic instances of jealousy or anger. But what are you left with if you omit the details? What would remain of Karenin's existential crisis?The novelist's privileged access to subjectivity is, of course, unavailable to the scientist, but the larger context of plot and character—a history of relations that gives emotional episodes their shape and power—has its analog in the ethnographic domain. Emotions are public as well as private events, their meanings and effects depending on a fit with social reality, a clash of perspectives. In thought and feeling, we are never really alone. All of which suggests that narrative, fictional or nonfictional, can capture the ongoing moment in a way that eludes other methods. If what we are after is living emotion, it is the movie, not the snapshot, that surely matters. No point in comparing “emotions” no one ever really experienced outside of an experiment.But there's the rub. In generalization—the goal of emotion theory—an emotion's social meaning, personal significance, pragmatic function, and narrative context get stripped out. All that makes it what it is! Even in doggedly empirical anthropology, detailed emotional episodes are rare (Jean Briggs's Utku ethnography Never in Anger, published in 1970, is still unsurpassed). Instead we get recollections and summary examples, lacking the constitutive detail, real-time evolutions, and consequences of the real thing. Yet these must serve for comparison, fodder for countless theoretical speculations. Are we at risk of analyzing faux emotions and building theories on cardboard constructions?An empty Arctic stage, a handful of characters, life simplified to survival: Briggs is a hard act to follow. Bare life does not make for basic emotions. On the white set, emotions prove hard to parse. That gruff hesitation, that flashing glint—are they tokens of anger? Empathy will not suffice. As Briggs shows, narrative context is all. And in our more cluttered emotional worlds, the value of backstory, interwoven biographies, and emotional plots is all the greater. Flanagan is right; we must do emotions better. (shrink)
