Cornell University and Zamorano (ThePanamerican School of Agriculture) facilitatedworkshops that provided Honduran and Nicaraguanfarmers new experience with plant diseases and helpedfarmers assimilate information and identify diseasemanagement alternatives. After learning about thebiology of plant diseases, farmers were able toidentify disease problems in their field, enablingthem to use pesticides more selectively. Furthermore,participants of seven courses conceived 273 pathogen-specificmanagement alternatives, and they identifiedon average 66 percent of the common recommendations by plantpathologists for the control of general disease types.Many ideas were novel and may (...) represent newopportunities for improving the practice of diseasemanagement.

Güinope, Honduras was the site of a highly acclaimed people-centered development project in the 1980s. The ACORDE/Ministry of Natural Resource/World Neighbors Integrated Development Program (IDP) was unique for its time, since rather than relying on technology transfer, it promoted innovation skills for local generation of responses to needs. Furthermore, it was one of the first efforts in Latin America to employ villagers as principal agents of change. Fifteen years after the inception of the IDP and ten years after its completion, (...) the authors interviewed farmers in their fields and held a series of participatory workshops over eighteen months with ten outstanding farmers who had become project leaders. The leaders identified influential factors behind their involvement and produced recommendations for rural development interventions. Further, a generalized concept map typifying ideal characteristics for farmer promoters was constructed. Recommendations for development agencies centered on project design and implementation, demanding a methodology for strengthening local innovative capacities, participation, and control over resources. Ultimately, the leaders downplayed the role of technologies in rural development and called for special attention to enabling communities to confront external pressures, in particular recent government ``modernization'' policies, that they felt threatened community livelihood.

Depression is ranked as most common type of mental illness by the World Health Organization. Although cognitive behavioural therapy is recommended as the evidence-based psychological treatment of choice, this applies mostly to youthful, attractive, verbal, intelligent and successful persons with medical aid support in high income countries. More holistic counselling that includes holistic, verbal and non-verbal, expressive therapeutic modalities are more suitable for the planetary majority. Consequently, this study describes the process and effectiveness of philophonetics counselling with a sample of (...) ten depressed clients seeking clinical psychological services in Zululand, South Africa, a region and country beset with considerable violence, crime illness and unemployment. Client reports of effectiveness of philophonetics counselling warrants further intervention and evaluative research, with special reference to wider community psychological applications of this expressive therapeutic modality via primary health care facilities, online courses and mobile technology.

Darwinism, Democracy, and Race examines the development and defence of an argument that arose at the boundary between anthropology and evolutionary biology in twentieth-century America. In its fully articulated form, this argument simultaneously discredited scientific racism and defended free human agency in Darwinian terms. The volume is timely because it gives readers a key to assessing contemporary debates about the biology of race. By working across disciplinary lines, the book's focal figures--the anthropologist Franz Boas, the cultural anthropologist Alfred Kroeber, the (...) geneticist Theodosius Dobzhansky, and the physical anthropologist Sherwood Washburn--found increasingly persuasive ways of cutting between genetic determinist and social constructionist views of race by grounding Boas's racially egalitarian, culturally relativistic, and democratically pluralistic ethic in a distinctive version of the genetic theory of natural selection. Collaborators in making and defending this argument included Ashley Montagu, Stephen Jay Gould, and Richard Lewontin. Darwinism, Democracy, and Race will appeal to advanced undergraduates, graduate students, and academics interested in subjects including Philosophy, Critical Race Theory, Sociology of Race, History of Biology and Anthropology, and Rhetoric of Science.

The increasing global demand for energy necessitates devoted attention to the formulation and exploration of mechanisms of thermal heat exchangers to explore and save heat energy. Thus, innovative thermal transport fluids require to boost thermal conductivity and heat flow features to upsurge convection heat rate, and nanofluids have been effectively employed as standard heat transfer fluids. With such intention, herein, we formulated and developed the constitutive flow laws by utilizing the Rossland diffusion approximation and Stephen’s law along with the (...) MHD effect. The mathematical formulation is based on boundary layer theory pioneered by Prandtl. Governing nonlinear partial differential flow equations are changed to ODEs via the implementation of the similarity variables. A well-known computational algorithm BVPh2 has been utilized for the solution of the nonlinear system of ODEs. The consequence of innumerable physical parameters on flow field, thermal distribution, and solutal field, such as magnetic field, Lewis number, velocity parameter, Prandtl number, drag force, Nusselt number, and Sherwood number, is plotted via graphs. Finally, numerical consequences are compared with the homotopic solution as a limiting case, and an exceptional agreement is found. (shrink)

S. 39: "My project in this paper is to develop the initial distinction which I have drawn between recognition and appraisal respect into a more detailed and specific account of each. These accounts will not merely be of intrinsic interest. Ultimately I will use them to illuminate the puzzles with which this paper began and to understand the idea of self-respect." 42 " Thus, insofar as respect within such a pursuit will depend on an appraisal of the participant from the (...) perspective of whatever standards are held to be appropriate to the pursuit, such respect will depend on a judgement to which excellences of character are thought relevant. Note that exactly what aspect of the person's character is thought to be relevant in this instance is his recognition respect (or lack of it) for the standards of the pursuit." 44 "This attitude fails of being appraisal respect in that my having it toward the person is conditional on those traits being such as to make him server a particular purpose that I happen to have" 44 - 45 "To sum up: Appraisal respect is an attitude of positibe appraisal of a person either judged as a person or as engaged in some more specific pursuit. In the first case, the appropriate grounds are features of the person's character: dispositions to act for particular reasons or a higher-level disposition to act for the best reasons. In the second case, though features of character do not exhaust the appropriate grounds for appraisal respect, some such character traits will be relevant (recognition respect for the standards of a particular pursuit). Also, the other features which constitute the appoprate excellences of the pursuit must be related to traits of character in the way specified. In both cases, the positive appraisal of the person, and of his traits, must be categorical. It cannot depend on the fact that the person, because of his traits, serves an interest or purpose of one's own." 45 "To have recognition respect for someone as a person is to give appropriate weight to the fact that he or she is a person by being willing to constrain one's behaviour in ways required by that fact." 45 "This is rather different from having an attitude of appraisal respect for someone as a person. The latter is a positive appraisal oif an individual made with regard ti those features which are excellences of persons. As such, it is not owed to everone, for it may or may not be merited. When it is, what is merited is just the positive appraisal itself." 47 "Second, the only beings who are approriate objects of appraisal respect are those who are capable of acting for reasons and hence capable of conceiving of various facts as meriting more or less consideration in deliberation.".

This work was the first sustained philosophical study of psychic phenomena to follow C.D. Broad's LECTURES ON PSYCHICAL RESEARCH, written nearly twenty years ...

This essay grows out of the conviction that recent work by psychologists studying human reasoning has important implications for a broad range of philosophical issues. To illustrate our thesis we focus on Nelson Goodman's elegant and influential attempt to "dissolve" the problem of induction. In the first section of the paper we sketch Goodman's account of what it is for a rule of inference to be justified. We then marshal empirical evidence indicating that, on Goodman's account of justification, patently invalid (...) inferential rules turn out to be "justified." We conclude that something is seriously wrong with Goodman's story about justification. In the second section we attempt to patch Goodman's account. The notion of epistemic authority and the social aspect of justification play central roles in the alternative account of justification that we propose. (shrink)

Michael Dummett and Dag Prawitz have argued that a constructivist theory of meaning depends on explicating the meaning of logical constants in terms of the theory of valid inference, imposing a constraint of harmony on acceptable connectives. They argue further that classical logic, in particular, classical negation, breaks these constraints, so that classical negation, if a cogent notion at all, has a meaning going beyond what can be exhibited in its inferential use. I argue that Dummett gives a mistaken elaboration (...) of the notion of harmony, an idea stemming from a remark of Gerhard Gentzen's. The introduction-rules are autonomous if they are taken fully to specify the meaning of the logical constants, and the rules are harmonious if the elimination-rule draws its conclusion from just the grounds stated in the introduction-rule. The key to harmony in classical logic then lies in strengthening the theory of the conditional so that the positive logic contains the full classical theory of the conditional. This is achieved by allowing parametric formulae in the natural deduction proofs, a form of multiple-conclusion logic. (shrink)

It is a commonplace that ‘autonomy’ has several different senses in contemporary moral and political discussion. The term’s original meaning was political: a right assumed by states to administer their own affairs. It was not until the nineteenth century that ‘autonomy’ came (in English) to refer also to the conduct of individuals, and even then there were, as now, different meanings.1 Odd as it may seem from our perspective, one that was in play from the beginning was Kant’s notion of (...) “autonomy of the will,”2 as Kant defined it, “the property of the will by which it is a law to itself independently of any property of the objects of volition” (4:440).3That’s a mouthful, to say the least.

The correspondence theory of truth has experienced something of a revival recently in the form of the Truthmaker Axiom: whatever is true, something makes it true. We consider various postulates which have been proposed to characterize truthmaking, in particular, the Disjunction Thesis (DT), that whatever makes a disjunction true must make one or other disjunct true. In conjunction with certain other assumptions, DT leads to triviality. We show that there are elaborations of truthmaking on which DT holds (which must therefore (...) take steps to avoid the triviality); but that there are more plausible accounts of truthmaking on which DT fails.

Bell’s theorem has fascinated physicists and philosophers since his 1964 paper, which was written in response to the 1935 paper of Einstein, Podolsky, and Rosen. Bell’s theorem and its many extensions have led to the claim that quantum mechanics and by inference nature herself are nonlocal in the sense that a measurement on a system by an observer at one location has an immediate effect on a distant entangled system. Einstein was repulsed by such “spooky action at a distance” and (...) was led to question whether quantum mechanics could provide a complete description of physical reality. In this paper I argue that quantum mechanics does not require spooky action at a distance of any kind and yet it is entirely reasonable to question the assumption that quantum mechanics can provide a complete description of physical reality. The magic of entangled quantum states has little to do with entanglement and everything to do with superposition, a property of all quantum systems and a foundational tenet of quantum mechanics.

have come in for increasing attention and controversy. A good example would be recent debates about moral realism where question of the relation between ethics (or ethical judgment) and the will has come to loom large.' Unfortunately, however, the range of positions labelled internalist in ethical writing is bewilderingly large, and only infrequently are important distinctions kept clear.2 Sometimes writers have in mind the view that sincere assent to a moral (or, more generally, an ethical) judgment concerning what one should (...) do is necessarily connected to motivation (actual or dispositional).s This necessity may be conceptual, or perhaps metaphysical, the thought being..

Tracing the history of American sociology since the Civil War, the authors of this important volume explain the field′s diversity, its lack of unifying paradigms, its broad, eclectic research agenda and its general weakness as an institutional force in either academia or the policy arena. They highlight the equivocal and often contradictory missions that sociologists prescribe for themselves and the variable nature of human, financial and intellectual resources available to the profession.

A mass problem is a set of Turing oracles. If P and Q are mass problems, we say that P is weakly reducible to Q if every member of Q Turing computes a member of P. We say that P is strongly reducible to Q if every member of Q Turing computes a member of P via a fixed Turing functional. The weak degrees and strong degrees are the equivalence classes of mass problems under weak and strong reducibility, respectively. We (...) focus on the countable distributive lattices P w and P s of weak and strong degrees of mass problems given by nonempty Π 1 0 subsets of 2 ω . Using an abstract Gödel/Rosser incompleteness property, we characterize the Π 1 0 subsets of 2 ω whose associated mass problems are of top degree in P w and P s , respectively. Let R be the set of Turing oracles which are random in the sense of Martin-Löf, and let r be the weak degree of R. We show that r is a natural intermediate degree within P w . Namely, we characterize r as the unique largest weak degree of a Π 1 0 subset of 2 ω of positive measure. Within P w we show that r is meet irreducible, does not join to 1, and is incomparable with all weak degrees of nonempty thin perfect Π 1 0 subsets of 2 ω . In addition, we present other natural examples of intermediate degrees in P w . We relate these examples to reverse mathematics, computational complexity, and Gentzen-style proof theory. (shrink)

This paper is a discussion of David Albert's approach to the foundations of classical statistical menchanics. I point out a respect in which his account makes a stronger claim about the statistical mechanical probabilities than is usually made, and I suggest what might be motivation for this. I outline a less radical approach, which I attribute to Boltzmann, and I give some reasons for thinking that this approach is all we need, and also the most we are likely to get. (...) The issue between the two accounts turns out to be one about the explanatory role probabilities play in statistical mechanics. (shrink)

Let ω be the set of natural numbers. For functions f, g: ω → ω, we say f is dominated by g if f < g for all but finitely many n ∈ ω. We consider the standard “fair coin” probability measure on the space 2ω of in-finite sequences of 0's and 1's. A Turing oracle B is said to be almost everywhere dominating if, for measure 1 many X ∈ 2ω, each function which is Turing computable from X is (...) dominated by some function which is Turing computable from B. Dobrinen and Simpson have shown that the almost everywhere domination property and some of its variant properties are closely related to the reverse mathematics of measure theory. In this paper we exposit some recent results of Kjos-Hanssen, Kjos-Hanssen/Miller/Solomon, and others concerning LR-reducibility and almost everywhere domination. We also prove the following new result: If B is almost everywhere dominating, then B is superhigh, i. e., 0″ is truth-table computable from B ′, the Turing jump of B. (shrink)

Principia Ethica set the agenda for analytical metaethics. Moore’s unrelenting focus on fundamentals both brought metaethics into view as a potentially separate area of philosophical inquiry and provided a model of the analytical techniques necessary to pursue it.1 Moore acknowledged that he wasn’t the first to insist on a basic irreducible core of all ethical concepts. Although he seems not to have appreciated the roots of this thought in eighteenth-century intuitionists like Clarke, Balguy, and Price, not to mention sentimentalists like (...) Hutcheson and Hume, Moore gave full marks to Sidgwick. According to Moore, Sidgwick was the “only . . . ethical writer” to have clearly seen the irreducibility of ethics’ defining notion.2 Nevertheless, twentieth-century meta-. (shrink)

Sober and Wilson have propose a cluster of arguments for the conclusion that “natural selection is unlikely to have given us purely egoistic motives” and thus that psychological altruism is true. I maintain that none of these arguments is convincing. However, the most powerful of their arguments raises deep issues about what egoists and altruists are claiming and about the assumptions they make concerning the cognitive architecture underlying human motivation.

The proper statement and assessment of Russell's theory depends on one's semantic presuppositions. A semantic framework is provided, and Russell's theory formulated in terms of it. Referential uses of descriptions raise familiar problems for the theory, to which there are, at the most general level of abstraction, two possible Russellian responses. Both are considered, and both found wanting. The paper ends with a brief consideration of what the correct positive theory of definite descriptions might be, if it is not the (...) Russellian theory.

I discuss three theories regarding the interpretation of fictional literature: actual intentionalism (author's intentions constrain how their works are to be interpreted), hypothetical intentionalism (interpretations are justified as those most likely intended by a postulated author), and the value-maximizing theory (interpretations presenting the work in the most favourable light are to be preferred). I claim that actual intentionalism cannot account for the appropriateness or legitimacy of some interpretations, or alternatively that it must be weakened to the point that the considerations (...) raised by hypothetical intentionalists and value maximizers come into play. And I argue that hypothetical intentionalism either reduces to the value-maximizing theory, which provides a more accurate and clearer expression of the position than does hypothetical intentionalism, or it mistakenly attributes to hypothesized intentions the kind of force that attaches only to actual intentions.

It is usually maintained by biologists and philosophers alike that essentialism is incompatible with evolutionary biology, and that abandoning essentialism was a precondition of progress being made in the biological sciences. These claims pose a problem for anyone familiar with both evolutionary biology and current metaphysics. Very few current scientific theories enjoy the prestige of evolutionary biology. But essentialism – long in the bad books amongst both biologists and philosophers – has been enjoying a strong resurgence of late amongst analytical (...) philosophers with a taste for metaphysics. Indeed, to impartial observers it is likely to appear that both evolutionary biology and essentialism are as well supported in their respective domains as could reasonably be expected. There is thus at least a prima facie tension here between evolutionary biology, metaphysics and, as we shall see, pre-theoretical common sense. (shrink)

According to Peter Kivy, to be profound, music would have to be about a profound subject that is treated in an exemplary way. Instrumental music does not satisfy this definition; usually it is not about anything humanly important, and when it is, it can convey no more than banalities. Like others, I argue against the propositional character of Kivy's ‘aboutness’ criterion; profundity can be revealed or displayed other than via statements and descriptions. I am less inclined than some of Kivy's (...) critics to argue that music conveys profound insights into the emotions or abstract metaphysical ideas, such as unity and identity. Instead, I draw a parallel with great chess, which illustrates the fecundity, flexibility, insight, vitality, subtlety, complexity, and analytical far-reachingness of which the human mind is capable. That demonstration is of deep significance, given the wider importance of an appreciation of our intellectual and imaginative powers, even if chess says nothing about the skills to which it draws attention. My thesis is that some instrumental music is profound in a similar way; namely, for what it exemplifies and thereby reveals about the capacities of the human mind. (shrink)

In this paper, I discuss what I call the oversized experiences that anorexic patients suffer from. It has been known for some time that anorexic patients mentally picture their bodies as larger than reality. While this constitutes one kind of oversized experience, I claim there is another, less explored kind. This is an experience of the body as oversized in relation to the affordances of its environment. I discuss recent evidence suggesting anorexic patients exhibit distorted affordance perception. I then discuss (...) how this distorted affordance perception also constitutes an oversized experience of the body. Along with sociocultural influences, I claim oversized experiences ground negative propositional attitudes regarding body size. (shrink)

This paper falls into two parts. In the first part, I argue that consideration of general indicative conditionals, e.g., sentences like If a donkey brays it is beaten, provides a powerful argument that a pure material implication analysis of indicative if p, q is correct. In the second part I argue, opposing writers like Jackson, that a Gricean style theory of pragmatics can explain the manifest assertability conditions of if p, q in terms of its conventional content – assumed to (...) be merely (p⊃q) – and the conversational implicature contents which utterance of if p, q may gain in certain contexts. I also defend the pragmatic approach against a recent objection by Edgington that appeal to pragmatics cannot explain what we are inclined to say about the believability conditions, as opposed to the assertability conditions, of indicative if p, q.

In their paper "Why Gibbs Phase Averages Work--The Role of Ergodic Theory" (1980), David Malament and Sandy Zabell attempt to explain why phase averaging over the microcanonical ensemble gives correct predictions for the values of thermodynamic observables, for an ergodic system at equilibrium. Their idea is to bypass the traditional use of limit theorems, by relying on a uniqueness result about the microcanonical measure--namely, that it is uniquely stationary translation-continuous. I argue that their explanation begs questions about the relationship between (...) thermodynamic equilibrium and statistical equilibrium; I argue in addition that any account which supports their view of the relationship between these two notions of equilibrium will likely use the limit theorems in traditional ways, and thereby bypass the explanation they offer.

A perennial problem in interpreting Hobbes’s moral and political thought in Leviathan has been to square the apparently irreducible normativity of central Hobbesian concepts and premises with his materialism and empiricism. Thus, Hobbes defines a “law of nature” as a “precept or general rule, found out by reason, by which a man is forbidden to do that which is destructive of his life” and the “right of nature” as “the liberty each man hath to use his own power, as he (...) will himself, for the preservation of his own nature”. Both are plainly normative. A law of nature is a precept that tells us what we ought not, or must not, do. And the right of nature tells us what we may do. (shrink)

In the early decades of the seventeenth century, various attempts were made to develop a dynamical vocabulary on the basis of work in the practical mathematical disciplines, particularly statics and hydrostatics. The paper contrasts the Mechanica and Archimedean approaches, and within the latter compares conceptions of statics and hydrostatics and their possible extensions in the work of Stevin, Beeckman and Descartes. Descartes’ approach to hydrostatics, a discussion of which forms the core of the paper, is shown to be quite different (...) from that of his contemporaries, above all in its attempt to provide a natural-philosophical grounding for hydrostatics while at the same time using it to develop a range of concepts, approaches and ways of thinking through problems that would shape Descartes’ mature work in optics and cosmology.Author Keywords: Scientific revolution; René Descartes; Isaac Beeckman; Simon Stevin; History of mechanics; History of statics; History of optics.
