This study is based on interviews with two groups of primary school children after they had completed a project in which children were taught in mixed-ability and mixed-gender groups with the purpose of improving their literacy. It examines the organisation of the children and the collaborative style of learning they were engaged in. Presentation of findings take the form of transcribed extracts from the group interviews. In analysing the children's comments, it is argued that mixed-ability teaching provides a setting in (...) which both low- and high-achieving students value the opportunity to work together where both groups believed they benefited. The study suggests that interactions among peers can facilitate literacy development in individual children. At a time when teachers are being asked to group children according to attainment, especially for the literacy hour, the potential benefits of mixed-ability teaching should not be ignored. (shrink)
This paper explores John Maynard Smith’s conceptual work on animal signals. Maynard Smith defined animal signals as traits that (1) change another organism’s behaviour while benefiting the sender, that (2) are evolved for this function, and that (3) have their effects through the evolved response of the receiver. Like many ethologists, Maynard Smith assumed that animal signals convey semantic information. Yet his definition of animal signals remains silent on the nature of semantic information and on the conditions (...) determining its content. I therefore compare three ways to specify the semantic content of animal signals. The first suggestion models semantic content on Maynard Smith’s theory of genetic information. On the second proposal, semantic content is equated with a condition identified by conventional content ascriptions. The third suggestion is to explain semantic content in terms of consumer-based teleosemantics. I show how these accounts equate semantic content with distinct kinds of conditions and how they differ with respect to the kinds of traits that qualify as carrying semantic information. (shrink)
Approaches to animal communication have for the most part been quite different in semiotics and evolutionary biology. In this context the writings of a leading evolutionary biologist who has also been attracted to semiotics — John Maynard Smith — are an interesting exception and object of study. The present article focuses on the use and adaptation of semiotic terminology in Maynard Smith’s works with reference to general theoretical premises both in semiotics and evolutionary biology. In developing a typology (...) of animal signals, Maynard Smith employs the concepts of icon, index and symbol to denote distinct signal classes.He uses “indices” or “indexes” to express a signal type where the relation between signal properties and meaning is restricted because of physical characteristics. Such approach also points out the issue of the motivatedness of signs, which has had a long history in semiotics. In the final part of the article the usage and content of the concepts of signal form and meaning in Maynard Smith’s writings are analysed. It appears that in evolutionary biology, the “signal” is a vague concept that may denote a variety of things from an animal’s specific physiological status to artificial theoretical constructs. It also becomes evident that in actual usage the concept of signal often includes references to the receiver’s activity and interpretation, which belong rather to the characteristics of sign process. The positive influence of Maynard Smith’s works on semiotics could lie in paying attention to the role of physical necessities in animal communication. Physicalconstraints and relations also seem to have a significant role in semiotic processes although this is not always sufficiently studied or understood in semiotics. (shrink)
Hugh Everett III proposed that a quantum measurement can be treated as an interaction that correlates microscopic and macroscopic systems—particularly when the experimenter herself is included among those macroscopic systems. It has been difficult, however, to determine precisely what this proposal amounts to. Almost without exception, commentators have held that there are ambiguities in Everett’s theory of measurement that result from significant—even embarrassing—omissions. In the present paper, we resist the conclusion that Everett’s proposal is incomplete, and we develop a close (...) reading that accounts for apparent oversights. We begin by taking a look at how Everett set up his project—his method and his criterion of success. Illuminating parallels are found between Everett’s method and then-contemporary thought regarding inter-theoretic reduction. Also, from unpublished papers and correspondence, we are able to piece together how Everett judged the success of his theory of measurement, which completes our account of his intended contribution to the resolution of the quantum measurement problem.

The question of what constitutes a finished work is thrown open, reminding us that in certain of his completed autographs Beethoven continued the process that he normally reserved for the earlier stages of composition, setting out further choices, possibilities, and interchangeabilities, including radical alterations in goal as well as detail. In particular, the revision of movement endings was one of his long-standing preoccupations. In works of his middle period, Emil Platen observed, Beethoven continued to make essential alterations in the closing (...) sections of movements after the works had already taken concrete notational form; for example, in the scores of the String Quartets, op. 59, “out of a total of seven movement endings, six were altered after the fact, four in essential ways.”6 Indeed the relationship between sketches and compositional goals was always more problematical than traditional scholars were willing to allow. As Lewish Lockwood has shown, the closer one looks at the sketches the less one can continue to accept as an article of faith that “as a work progresses from first inklings to final realization it should pass through successive phases of growth and clarification of structure, and of complication of detail in relation to that structure, becoming progressively more definite en route to its goal.”7 To further thicken the issue, Janet Levy has pointed out that one “cannot assume that the goals of a completed work are necessarily the same as the goals of the sketches for it,” inasmuch as the composer’s intentions may well have changed during the course of composition and we may be left with sketches made in connection with goals no longer reflected in the final work.8 Composition is only partly a teleological process whereby the composer eventually finds a lapidary form for a predetermined idea. With Beethoven, not only is there no prospective inevitability, there may even be no inevitability after the fact. His sketches and autographs may well be series of rough maps to the multiplicity of universes he glimpsed, to a plurality of possibilities, a jammed crossroads of paths taken and not taken. 6.

During the war, I worked in aircraft design. About a year after D-day, an exhibition was arranged at Farnborough of the mass of German equipment that had been captured, including the doodlebug and the V2 rocket. I and a friend spent a fascinating two days wandering round the exhibits. The questions that kept arising were ‘Why did they make it like that?’, or, equivalently ‘I wonder what that is for?’ We were particularly puzzled by a gyroscope in the control system (...) of the V2. One's first assumption was that the gyroscope maintained the rocket on its course, but, instead of being connected to the steering vanes, it was connected to the fuel supply to the rocket. Ultimately my friend remembered that the rate of precession of a gyro depends on acceleration, and saw that the Germans had used this fact to design an ingenious device for switching off the engines when the required velocity had been reached.

Using the results of a survey of animal rights activists, advocates, and supporters, the paper reveals much more convergence than divergence of attitudes and actions by male and female animal protectionists. Analysis of the divergence suggests that the differences between men and women in the movement are contingent upon such things as early socialization, gendered work and leisure patterns, affinity with companion animals, ambivalence about science, and a history of opposition to nonhuman animal abuse by generations of female activists and (...) animal advocates. Aside from the feminist and women's movements and groups like Mothers Against Drunk Driving, it is rare to find a social movement in which the standing of women eclipses those of their male colleagues. The paper suggests that animal protection remains a bastion of female activism and advocacy because women care about blood, flesh, and pain and, unlike earlier generations of animal activists, no longer are seen as a liability to the success of the movement.

The levels of selection problem was central to Maynard Smith’s work throughout his career. This paper traces Maynard Smith’s views on the levels of selection, from his objections to group selection in the 1960s to his concern with the major evolutionary transitions in the 1990s. The relations between Maynard Smith’s position and those of Hamilton and G.C. Williams are explored, as is Maynard Smith’s dislike of the Price equation approach to multi-level selection. Maynard Smith’s account (...) of the ‘core Darwinian principles’ is discussed, as is his debate with Sober and Wilson (1998) over the status of trait-group models, and his attitude to the currently fashionable concept of pluralism about the levels of selection.

One of the most remarkable aspects of John Maynard Smith’s work was the fact that he devoted time both to doing science and to reflecting philosophically upon its methods and concepts. In this paper I offer a philosophical analysis of Maynard Smith’s approach to modelling phenotypic evolution in relation to three main themes. The first concerns the type of scientific understanding that ESS and optimality models give us. The second concerns the causal–historical aspect of stability analyses of adaptation. (...) The third concerns the concept of evolutionary stability itself. Taken together, these three themes comprise what I call the natural philosophy of adaptation. (shrink)
Though the literature on the topic has been slim, several recent commentators have identified a close affinity between the philosophical project of Giorgio Agamben, as articulated in his Homo Sacer series, and René Girard's theory of mimetic rivalry with its resolution through sacrificial scapegoating.1 Both are theories of social unity made possible through highly ritualized forms of exclusion. Girard's work posits desire and its conflictual consequences as the ultimate ground for all social systems, while Agamben views the same systems with (...) an eye toward the maintenance of sovereign power. Agamben begins his study with an obscure figure of Roman law, the "sacred man," who is excluded from the laws of both the... (shrink)
Recent advances in paleoarchaeology show why nothing in the Tate Modern, where a conference on "Agency & Automatism" took place, challenges the roots of 'the idea of the fine arts' (Kristeller) as high levels of craft, aesthetics, mimesis and mental expression, as exemplifying cultures: it is by them that we define our species. This paper identifies and deals with resistances, early and late, to photographic fine art as based on concerns about automatism reducing human agency--that is, mental expression--then offers the (...) fuller account of agency lacking in such discussions. But fine art is not the only value classification we use. (shrink)
This paper addresses standard questions regarding comics and the arts (comics and fine arts, image and word combinations), then poses and addresses the neglected, but deeper and wider--thus philosophical--question, of how depictions, not just words, can have mental contents at all, including light, funny, scathing, comic ones.
Australia's Coalition Against Duck Shooting sees duck-shooting as a social problem and as an injustice with moral, legal and environmental consequences. The small animal liberationist group has succeeded in dramatically reducing the numbers of duck shooters in Victoria, which is the home of duck-shooting in Australia. The Coalition's framing work with the public via the electronic media involves three parts: a diagnosis , a prognosis and a motivational frame , all of which construct hunting as a cruel, antisocial blood sport (...) that ought to be banned. In this article, television news bulletins and feature stories from the 1993 and 1994 campaigns are analyzed to show how CADS makes and sustains its claims. In addition to 90 pages of transcripts of news commentaries and descriptive accounts of the visuals, the data include tape-recorded interviews with some of the duck liberationists involved in the campaign.

Philosophy's only celebration of photography's 150th, the long-neglected philosophical job of clarification: drawing basic distinctions and defining basic conceptions, including photographic depiction, photographic detection, 'photograph of', 'documentary'. More than a lexicon, it explains why photography is important, by historically characterizing it through its uses for depiction, detection, reproduction, all of which have shaped the modern world. By consideration of it as 'mechanical', the paper explains photography's differences from practices with which it shares these functions. Happy birthday, photography.
In a world of partially overlapping and partially conflicting interests there is good reason to doubt that self-seeking behaviour at the micro-level will spontaneously lead to desirable social outcomes at the macro-level. Nevertheless, some sophisticated economic writers advocating a laissez-faire policy prescription have proposed various 'invisible hand' mechanisms which can supposedly be relied upon to 'educe good from ill'. Smith defended the 'simple system of natural liberty' as giving the greatest scope to the unfolding of God's will and the working (...) out of 'natural' providential processes free of interference by 'artificial' state intervention - the expression not of divine order but of fallible human reason. Hayek, adopting a similar policy stance, based it in an evolutionary process in which those institutional forms best adapted to reconciling individual interests would, he believed, spontaneously be selected for in the inter-group struggle for survival. Keynes shares the holistic approach of Smith and Hayek, but without their reliance on invisible hand mechanisms. If spontaneous processes cannot be relied upon to generate desirable social outcomes then we have to take responsibility for achieving this ourselves by establishing the appropriate institutional framework. Keynes takes a historical view of the role of capitalism and analyses its pathology as rooted in what we would now refer to as a multi-player prisoners' dilemma. The paper draws out the significance of his methodological standpoint here. Keynes's policy standpoint assigns a critical role to his own class, the 'educated bourgeoisie' in the reform process he maps out. A distinction, but also an intimate connection, is highlighted between, on the one hand, micro-level individualism (the 'Manchester System, and, on the other, the macro-level collective action ('planning') required to preserve it. Finally Keynes is considered in relation to the themes of laissez-faire, holism, reductionism, providentialism and the invisible hand. (shrink)
Within the context of the study of the genetics of language, Chomskian laws of grammar, such as theStructure-dependence Condition and theA over A Condition, may be usefully regarded to have a status similar to that of Mendelian Laws in classical genetics. In both the case of Chomsky's Laws and Mendel's Laws, formal genetic principles are postulated which abstract away from the physical mechanisms involved and in both cases certain apparent counterexamples mirror a more complex underlying genetic organisation.
Popular science writing has received increasing interest, especially in its relation to professional science. I extend the current scholarly focus from the nineteenth to the twentieth century by providing a microhistory of the early popular writings of evolutionary biologist John Maynard Smith. Linking them to the state of evolutionary biology as a professional science as well as Maynard Smith’s own professional standing, I examine the interplay between author, text and audiences. In particular, I focus on Maynard Smith’s (...) book The Theory of Evolution and show how he used it to both promote neo-Darwinism and advocate the utility of mathematics in biology. Following in the footsteps of Charles Darwin and David Lack, Maynard Smith was a science communicator blurring the lines between genres and audiences while contributing to ongoing discussions within and on the profession of evolutionary biology around the Darwin-Wallace centenary.

Nanomedicine is yielding new and improved treatments and diagnostics for a range of diseases and disorders. Nanomedicine applications incorporate materials and components with nanoscale dimensions where novel physiochemical properties emerge as a result of size-dependent phenomena and high surface-to-mass ratio. Nanotherapeutics and in vivo nanodiagnostics are a subset of nanomedicine products that enter the human body. These include drugs, biological products, implantable medical devices, and combination products that are designed to function in the body in ways unachievable at larger scales. (...) Nanotherapeutics andin vivonanodiagnostics incorporate materials that are engineered at the nanoscale to express novel properties that are medicinally useful. These nanomedicine applications can also contain nanomaterials that are biologically active, producing interactions that depend on biological triggers. Examples include nanoscale formulations of insoluble drugs to improve bioavailability and pharmacokinetics, drugs encapsulated in hollow nanoparticles with the ability to target and cross cellular and tissue membranes and to release their payload at a specific time or location, imaging agents that demonstrate novel optical properties to aid in locating micrometastases, and antimicrobial and drug-eluting components or coatings of implantable medical devices such as stents.

Entering into conversation with the theological work of Michael Patrick Murphy and Hans Urs von Balthasar, this essay articulates a starting-point for reading Shusaku Endo’s Silence and exploring its relevance for contemporary discussions between Christian aesthetics and postmodernism. Under particular examination are the ways in which both Endo and Balthasar bring postmodern hermeneutics into conversation with Christian eschatology to address questions of knowledge and identity, examining not only how themes of resurrection appear aesthetically in the novel, but also how reading (...) the novel from within this thematic framework speaks to its central concerns. Thus, this essay articulates an anticipatory or eschatological hermeneutic which hopes to do justice to both the violence of Endo’s story and the hope of the Christian narrative. (shrink)

This article addresses a countermovement to the animal liberation movement and its campaigns against vivisection, factory farming, and recreational hunting in the United States, the United Kingdom, and Australia. As moderate welfarists, pragmatic animal liberationists , and radical abolitionists who advocate animal rights, animal protectionists campaign for animals. The countermovement defends acts that animal protectionists decry. Meanwhile, sociologists accord little study to interplay between the movements . In Buechler's and Cylke's collection of 34 papers on social movements , only one (...) paper focused on countermovements, describing the connection between social movement and countermovement as "a continuous dialect of social change" . Although extensive writings exist on the main campaigns of the animal liberation movement, little scholarly material exists on the defenses mounted by the countermovement. This article examines key elements of a values war, a struggle over moral capital waged by animal protectionists and their countermovement opponents. (shrink)
Maynard Smith’s defenses of adaptationism and of the value of optimization theory in evolutionary biology are both criticized. His defense does not adequately respond to the criticism of adaptationism by Gould and Lewontin. It is also argued here that natural selection cannot be interpreted as an optimization process if the objective function to be optimized is either (i) interpretable as a fitness, or (ii) correlated with the mean population fitness. This result holds even if fitnesses are frequency-independent; the problem (...) is further exacerbated in the frequency-dependent context modeled by evolutionary game theory. However, Eshel and Feldman’s new results on “long-term” evolution may provide some hope for the continuing relevance of the game-theoretic framework. These arguments also demonstrate the irrelevance of attempts by Intelligent Design creationists to use computational limits on optimization algorithms as evidence against evolutionary theory. It is pointed out that adaptation, natural selection, and optimization are not equivalent processes in the context of biological evolution. (shrink)
