This report describes the rationale, approaches, organization, and resource development leading to a large-scale deletion bin map of the hexaploid wheat genome. Accompanying reports in this issue detail results from chromosome bin-mapping of expressed sequence tags representing genes onto the seven homoeologous chromosome groups and a global analysis of the entire mapped wheat EST data set. Among the resources developed were the first extensive public wheat EST collection. Described are protocols for sequencing, sequence processing, EST nomenclature, and the assembly of (...) ESTs into contigs. These contigs plus singletons were used for selection of distinct sequence motif unigenes. Selected ESTs were rearrayed, validated by 5′ and 3′ sequencing, and amplified for probing a series of wheat aneuploid and deletion stocks. Images and data for all Southern hybridizations were deposited in databases and were used by the coordinators for each of the seven homoeologous chromosome groups to validate the mapping results. Results from this project have established the foundation for future developments in wheat genomics. (shrink)

Understanding terrestrial carbon metabolism is critical because terrestrial ecosystems play a major role in the global carbon cycle. Furthermore, humans have severely disrupted the carbon cycle in ways that will alter the climate system and directly affect terrestrial metabolism. Changes in terrestrial metabolism may well be as important an indicator of global change as the changing temperature signal. Improving our understanding of the carbon cycle at various spatial and temporal scales will require the integration of multiple, complementary and independent methods (...) that are used by different research communities. Tools such as air sampling networks, inverse numerical methods, and satellite data allow us to study the strength and location of the global- and continental-scale carbon sources and sinks. Bottom-up studies provide estimates of carbon fluxes at finer spatial scales and examine the mechanisms that control fluxes at the ecosystem, landscape, and regional scales. Bottom-up approaches include comparative and process studies that provide the necessary mechanistic information to develop and validate terrestrial biospheric models. An iteration and reiteration of top-down and bottom-up approaches will be necessary to help constrain measurements at various scales. We propose a major international effort to coordinate and lead research programs of global scope of the carbon cycle. (shrink)

A subspace V of an infinite dimensional fully effective vector space V ∞ is called decidable if V is r.e. and there exists an r.e. W such that $V \oplus W = V_\infty$ . These subspaces of V ∞ are natural analogues of recursive subsets of ω. The set of r.e. subspaces forms a lattice L(V ∞ ) and the set of decidable subspaces forms a lower semilattice S(V ∞ ). We analyse S(V ∞ ) and its relationship with L(V (...) ∞ ). We show: Proposition. Let U, V, W ∈ L(V ∞ ) where U is infinite dimensional and $U \oplus V = W$ . Then there exists a decidable subspace D such that U |oplus D = W. Corollary. Any r.e. subspace can be expressed as the direct sum of two decidable subspaces. These results allow us to show: Proposition. The first order theory of the lower semilattice of decidable subspaces, Th(S(V ∞ )), is undecidable. This contrasts sharply with the result for recursive sets. Finally we examine various generalizations of our results. In particular we analyse S * (V ∞ ), that is, S(V ∞ ) modulo finite dimensional subspaces. We show S * (V ∞ ) is not a lattice. (shrink)

The rôle of mathematical models in growth studies is discussed and a distinction made between the structural and descriptive aspects of a mathematical formulation. A simple scheme is set up to represent in broad outline the simultaneous growth and interaction of larval and adult systems inMyrmica rubra and is matched against observed results.

A critical review of gravitational wave theory is made. It is pointed out that the usual linear approach to the gravitational wave theory is neither conceptually consistent nor mathematically justified. Relying upon that analysis it is argued that—analogously to a Yang-Mills propagating field, which must be nonlinear to carry its gauge charge—a gravitational wave must necessarily be nonlinear to transport its own charge—that is, energy-momentum.

We present here a direct elementary construction of continuous utility functions on perfectly separable totally preordered sets that does not make use of the well-known Debreu’s open gap lemma. This new construction leans on the concept of a separating countable decreasing scale. Starting from a perfectly separable totally ordered structure, we give an explicit construction of a separating countable decreasing scale, from which we show how to get a continuous utility map.

This article is an attempt to clarify a confusion in the brain death literature between logical sufficiency/necessity and natural sufficiency/necessity. We focus on arguments that draw conclusions regarding empirical matters of fact from conceptual or ontological definitions. Specifically, we critically analyze arguments by Tom Tomlinson and Michael B. Green and Daniel Wikler. which, respectively, confuse logical and natural sufficiency and logical and natural necessity. Our own conclusion is that it is especially important in discussing the brain death issue to observe (...) the distinction between logical and natural sufficiency/necessity in a strict fashion.

A collection of essays exploring the relationship between Plato and the poet Hesiod. The volume covers a wide variety of thematic angles, brings new and sometimes surprising light to a large range of Platonic dialogues, and represents a major contribution to the study of the reception of archaic poetry in Athens.

Professor Hall with this work supplements the earlier bibliography of T. E. Jessop, who has collaborated on some of the entries in the current work. There is an overlap of some ten years, inasmuch as Hall’s work commences with the year 1930; entries run through early 1971. The bibliography is extensive, containing some 800 items in all the various Western languages as well as transliterated Japanese. In addition, attention is directed to critical studies of many of the listings. An eighteen-page (...) subject index contributes further to making this a quite useful and valuable addition to the field of Hume scholarship.—R. J. G. (shrink)

The title of this work evokes suspicion: how can Soll aim at one "part"--metaphysics--of a philosophy such as Hegel's? How would one go about introducing only Hegel's metaphysics? One might, with some validity, go about discussing Hegel's metaphysics ; but how would one, assuming his reader's general unfamiliarity with Hegel, introduce his "metaphysics," and that alone? Alas, one's worst fears are soon realized: the opening sentence reads, "Hegel's method is best approached by asking what he was trying to accomplish with (...) it." Bifurcation. The operant supposition which guides the work is that Hegel "has" a method with which he attempts to "do" various things. This view is utterly un-Hegelian, as even a cursory reading of the introduction to the Logic, to cite only one source, illustrates. No guide to Hegel is going to be useful that clouds this fundamental point. The whole texture of Hegel's integrated and integrative system is never rescued. Soll's presentation approaches, and treats of, Hegel from the standpoint of pedestrian philosophizing, leaning heavily on the collected tradition to make distinctions in a glib and altogether external way. From his starting point, Soll proceeds, drawing on a handful of secondary sources, to deliver an extended series of facile, shotgun commentaries: but if one already has the ability to adjudge which of them find their mark, he does not need the book in the first place. The primary problem a book of this kind faces is the perhaps insuperable difficulty of creating a suitable "introduction" to Hegel's thought. And to be fair, one might say that most of the shortcomings of Soll's book are attributable to this problem. Where does one start, if not where Hegel did; and whither does one proceed, except in the direction Hegel did? One should either attempt to go that path, or elect not to go at all. It is too easy to lose one's way in so dense a forest.--R. J. G. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Potential ethical issues can arise during the process of epidemiological classification. For example, unnatural infant deaths are classified as accidental deaths or homicides. Societal sensitivity to the physical abuse and neglect of children has increased over recent decades. This enhanced sensitivity could impact reported infant homicide rates. Infant homicide and accident mortality rates in boys and girls in the USA from 1940 to 2005 were analysed. In 1940, infant accident mortality rates were over 20 times greater than infant homicide rates (...) in both boys and girls. After about 1980, when the ratio of infant accident mortality rates to infant homicide rates decreased to less than five, and the sum of infant accident and homicide rates became relatively constant, further decreases in infant accident mortality rates were associated with increases in reported infant homicide rates. These findings suggest that the dramatic decline of accidental infant mortality and recent increased societal sensitivity to child abuse may be related to the increased infant homicide rates observed in the USA since 1980 rather than an actual increase in societal violence directed against infants. Ethical consequences of epidemiological classification, involving the principles of beneficence, non-maleficence and justice, are suggested by observed patterns in infant accidental deaths and homicides in the USA from 1940 to 2005.

This book is a collection of essays, and is an exercise in literary criticism. Most of the entries couple a philosopher with a literary artist, and the majority of these have an emphasis on the philosophical partner which one frequently fails to find in this sort of study. While few of the critics are capable of sustaining their subtle distinctions, a task properly required of a philosopher, it is nonetheless true that few philosophers can likewise do this. The ability to (...) systematically sustain these distinctions is what characterizes those first-order thinkers whom the body of philosophers and critics alike study. Granting this, the fact still remains that first-rate criticism is vastly more palatable intellectual fodder than is less than first-rate philosophizing. Studies such as the current one bring philosophy back into reality; the relation of a philosopher’s thought to his period, in all of the latter’s diversity, gives to that thought a realistic character that more transparently informs the creations of the fine arts than it does the original products of thought. And if thought is to avoid the sterility which so antagonized both a Sterne and a Hegel, and to become genuinely meaningful, this larger context will be forever indispensable.—R. J. G. (shrink)

The point of departure in this work is a defense against that view which would hold Hegel to be a glorifier of the Prussian state, a reactionary, and an enemy of freedom. Hegel, as the work illustrates, recognized that the French Revolution only annihilated what was already in itself destroyed; and he saluted it with "rapture" as the coming of a "new dawn" in the preface of the Encyclopaedia. He continued to celebrate its anniversary even while at the same time (...) and with no less intensity holding before himself an awareness of the dangers and horrors which it occasioned. In fact, Ritter submits that one might well understand the idea of freedom brandished by the Revolution to be the fundamental element of Hegel’s entire philosophy. Hegel disengages the notion of freedom from all previous connections which, over the centuries, have distorted it, and recovers the classic definition of Aristotle : "free is the man who is for himself and not for another." Political order must guarantee this possibility. The problem posited by the Revolution is: how? Hegel, the supposed "reactionary," in all his writings, both public and private, was consistently opposed, and occasionally with passion, to any political restoration. Yet one should also take notice of Hegel’s extreme and profound antipathy for the associations of students and demagogical movements, which he saw had no rapport with the real political and historical events of the time. Both the romantic liberal and the romantic conservative united in "hatred against the law." They were concerned not with freedom as such, but with political activity which pretended to be in its service, spewing platitudes which would renounce all searching knowledge and make truth an affair of the heart, the soul, or enthusiasm. Hegel alone, with perhaps the exception of Goethe, perceived the profound danger of anarchy revealed in these movements, a danger menacing to all, when one elevates pure subjectivity and sentiment to the rank of norm for political structures. The Revolution was accompanied by the dissolution of all the representations, concepts, and norms of the previous world as if they had been the fabric of dreams. In the face of this event, along with that of the constant danger of anarchy, philosophy must furnish the ideas which can determine that which can be conserved and that which can no longer survive. For both the advocates of restoration and the revolutionaries the Revolution was understood to be the end of previous history, the severing of man from his past: one wanted merely to recover it, the other to bury it. This scission, together with the real power which it has exerted on man and his conscience, is the fundamental structure of the new age. The remainder of the current study pursues the development of this scission, revealing the inner contradiction of the poles when taken alone: the scission itself to be the unity of historic existence in the form of subjectivity and objectivity; and the scission to find its objective expression in modern civil society. There is an on-going enrichment in the notion of freedom until it finds its fulfillment in the modern State, which assures freedom by providing the structures through which it can exist. Most of what should be said is said, although Ritter’s presentation occasionally harbors some confusion, a common and probably inescapable fate when one cuts in on the dialectic to forage for an isolated topic. Still, the book achieves its goal with admirable success, and is certainly a valuable tract on Hegel vis-à-vis the notion of political freedom. The main work is a translation from the German original; it is followed by an address which develops the material in the Philosophy of Right, § 34-81; and the book concludes with a rather amazing fifty-page bibliography citing the influence exercised by Hegel’s political theory throughout the nineteenth century.—R.
