Before Euro-American settlement, many Native American nations intercropped maize (_Zea mays_), beans (_Phaseolus vulgaris_), and squash (_Cucurbita pepo_) in what is colloquially called the “Three Sisters.” Here we review the historic importance and consequences of rejuvenation of Three Sisters intercropping (3SI), outline a framework to engage Native growers in community science with positive feedbacks to university research, and present preliminary findings from ethnography and a randomized, replicated 3SI experiment. We developed mutually beneficial collaborative research agendas with four Midwestern US Native (...) American nations. Ethnographic data highlighted a culturally based respect for 3SI as living beings, the importance it holds for all cultural facets of these Native nations, and the critical impact the practice has on environmental sustainability. One concern expressed by Native growers during ethnographic research was improving soil health—part of the rationale for establishing the 3SI agronomic experiment. To address this, we collaboratively designed a 3SI experiment. After 1 year, 3SI increased short-term soil respiration by 24%, decreased salt-extractable nitrate by 54%, had no effect on soil microbial biomass (but increased its carbon-to-nitrogen ratio by 32%) compared to the average of monoculture crops. The overarching purpose of this collaborative project is to develop a deeper understanding of 3SI, its cultural importance to Native communities, and how reinvigorating the practice—and intercropping in general—can make agroecosystems more sustainable for people and the environment.

_The purpose_ of the article is to comprehend the Husserlian model of constituting temporal modes through the ability of intentional "retentional-protentional" consciousness, as well as to clarify the possibility of interpreting its positions in the reconstruction of the concept of anthropic time. _Theoretical basis._ The theoretical framework of the research includes: 1) the interpretation of the phenomenological reflection of "time-consciousness" by E. Husserl in the context of solving the problem of phased-differentiation of this form of temporality; 2) the concept of (...) anthropic time (V. Khanzhy). _Originality._ For the first time in research literature, the possibilities of applying the ideas of Husserl to the reconstruction of the concept of anthropic time are considered through the interpretation of the phenomenological solution to the problem of temporality, proposed and specified in Husserl’s "time-consciousness" concept. _Conclusions._ The comprehension of the Husserlian model of intentionality of consciousness through the "grasping-from-now" and the constitution of phases of phenomenological time through the component of "exiting-from-now" showed that solving the problem of phased-differentiation of phenomenological time leads to the observation of the impossibility of isolating the modes of past, present, and future as self-sufficient and unconditional. More accurate indications, based on the constitutive intentionality of consciousness on the "grasping-from-now" phases of time (as conventional), are as follows: a) the abilities of retention and recollection are the foundation for the constitution of the past and its connections to the present; b) the perception establishes the basis for the phase of the present itself; c) the possibilities of protention and anticipation (as forms of imagination) constitute the future and its connections to the present. By the concept of retention, Husserl fixes a certain primary memory (the present "now" of a past interval), which enables retaining the past in the present. The category of recollection or secondary memory is used by the philosopher to refer to the self-sufficient reproduction of past experiences (without being joined to present perception). The fundamental difference between recollection and retention is that the former _re-_presents a temporal interval, grasping its content and reproducing it as it was in the past, while in the latter, the perceived duration is presented as a fragment of time that has just passed. According to the German philosopher, the "grasping" of the present phase is performed by perception. Through the constitutive intentionality of consciousness, perception synthesizes the results of primary-actual activity and retentional holding of duration. The second part of the article will present solutions to the following research tasks: 1) analysis of the possibilities of protention and anticipation in constituting the future and its connections with the present; 2) understanding the possibility of using interpreted forms of Husser’s ideas in reconstructing the concept of anthropic time.

Abduction is or subsumes a process of inference. It entertains possible hypotheses and it chooses hypotheses for further scrutiny. There is a large literature on various aspects of non-symbolic, subconscious abduction. There is also a very active research community working on the symbolic (logical) characterisation of abduction, which typically treats it as a form of hypothetico-deductive reasoning. In this paper we start to bridge the gap between the symbolic and sub-symbolic approaches to abduction. We are interested in benefiting from developments (...) made by each community. In particular, we are interested in the ability of non-symbolic systems (neural networks) to learn from experience using efficient algorithms and to perform massively parallel computations of alternative abductive explanations. At the same time, we would like to benefit from the rigour and semantic clarity of symbolic logic. We present two approaches to dealing with abduction in neural networks. One of them uses Connectionist Modal Logic and a translation of Horn clauses into modal clauses to come up with a neural network ensemble that computes abductive explanations in a top-down fashion. The other combines neural-symbolic systems and abductive logic programming and proposes a neural architecture which performs a more systematic, bottom-up computation of alternative abductive explanations. Both approaches employ standard neural network architectures which are already known to be highly effective in practical learning applications. Differently from previous work in the area, our aim is to promote the integration of reasoning and learning in a way that the neural network provides the machinery for cognitive computation, inductive learning and hypothetical reasoning, while logic provides the rigour and explanation capability to the systems, facilitating the interaction with the outside world. Although it is left as future work to determine whether the structure of one of the proposed approaches is more amenable to learning than the other, we hope to have contributed to the development of the area by approaching it from the perspective of symbolic and sub-symbolic integration.

There is no way literally to measure health, because health is multi-dimensional, and there is no metric whereby one person who is healthier than a second with respect to one dimension but less healthy with respect to another counts as healthier, less healthy or equally healthy overall. Health analysts instead measure how good or bad health states are in some regard. If these values are measures of health states, then identical health states must have identical values. But in different circumstances, (...) the same health state may have different values. It may be better or worse. Uniform values can nevertheless be assigned to kinds of health states, either as a weighted average of the values of their tokens or as the value of the performance in a standard environment of the capacity the health state constitutes. These uniform values are not well suited for some of the purposes for which summary measures of population health have been intended, and a set of non-evaluative indicators may be an attractive alternative.

The publish-or-perish paradigm is a prevailing facet of science. We apply game theory to show that, under rather weak assumptions, this publication scenario takes the form of a prisoner’s dilemma, which constitutes a substantial obstacle to beneficial delayed publication of more complete results. One way of avoiding this obstacle while allowing researchers to establish priority of discoveries would be an updated “pli cacheté”, a sealed envelope concept from the 1700s. We describe institutional rules that could additionally favour high-quality work and (...) publications and provide examples of such policies that are already in place. Our analysis should be extended to other publication scenarios and the role of other stakeholders such as scientific journals or sponsors. (shrink)

Literally before our eyes, the modeling of global development, or world modeling, has, during the past five to seven years, advanced from the initial experiments of individual groups of enthusiasts to the status of an independent sphere of scientific research enriched each year by new and ever larger teams of experts and by whole institutes.

Values of some arbitrary parameters appearing in a geometrical model for elementary particles developed by MacGregor are compared with quantities associated with classical properties of blocks of charges±e interacting via Coulomb forces and hard-sphere repulsion only. If it is assumed that masses and radii of individual charged particles are related bymc 2=(2/3)(e 2/r) and thatmc 2=6.87 MeV, then the self-energiesM andM ± of 24-particle neutral blocks and 25-particle charged blocks composed of layers of three octagons and of a square sandwiched (...) by two distorted octagons satisfyM=70.1 MeV,M ±=74.2 MeV. The binding energyB nn of pairs of neutral blocks is given byB nn=4.9 MeV, and the maximum radius of the neutral block is 0.60 F. These four calculated parameter values lie within an average of 1% of the corresponding quantities for nonspinning quarks determined empirically by MacGregor. (shrink)

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a comprehensive and (...) rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

The central insight of Darwin's Origin of Species is that evolution is an ecological phenomenon, arising from the activities of organisms in the 'struggle for life'. By contrast, the Modern Synthesis theory of evolution, which rose to prominence in the twentieth century, presents evolution as a fundamentally molecular phenomenon, occurring in populations of sub-organismal entities - genes. After nearly a century of success, the Modern Synthesis theory is now being challenged by empirical advances in the study of organismal development and (...) inheritance. In this important study, D. M. Walsh shows that the principal defect of the Modern Synthesis resides in its rejection of Darwin's organismal perspective, and argues for 'situated Darwinism': an alternative, organism-centred conception of evolution that prioritises organisms as adaptive agents. His book will be of interest to scholars and advanced students of evolutionary biology and the philosophy of biology. (shrink)

The purpose of this article should become plain during the reading of it, but perhaps some prior explanation is needed. Almost from the beginning of my study of the paṭiccasamuppāda I have had the notion that it could not have come into existence in the form the usual twelvefold formulation takes. For reasons which I try to make clear this twelvefold formulation is not a satisfactory statement of what it is supposed to explain, namely the reasons for each individual's continued (...) rebirths. I feel - and sadly I have to emphasize, before someone else does it for me, that in the final analysis I am relying more or less on intuition for my attitude towards the twelvefold formulation - that if one person alone had been responsible for the usually referred to formulation, and especially if that one person had been the Buddha, then those anomalies that now prevail would never have existed.

It is now some years since Professor D. Daiches Raphael published his interesting book, The Paradox of Tragedy , which represented one of the first serious attempts made by a British philosopher to assess the significance of tragic drama for ethical, and indeed metaphysical theory. Since then we have had a variety of books touching on related topics: for instance, Dr George Steiner's Death of Tragedy and Mr Raymond Williams’ most recent, elusive and interesting essay, Modern Tragedy. To entitle an (...) essay Theology and Tragedy might be thought to invite needless trouble for oneself; to indulge to a dangerous degree the human intellectual obsession of supposing that ‘the meaning of a word is an object’. After all, if one confines one's regard to the Greeks, one has to recognise that between the treatments of their common theme of Electra , Sophocles and Euripides are in fact doing very different things. There is no gainsaying the significance for Euripides of the postponement of the murder of Clytemnestra till after that of Aegisthus, still less of his introduction into the play of the morally upright peasant, who has had the banished Electra in his keeping, and whose simple integrity contrasts both with the corruption of the court and the obsessive preoccupation with a dreadful, supposed duty of brother and sister. The element of propaganda is unmistakable; while in Sophocles’ Electra it is altogether absent, although Dr Victor Ehrenberg in his very interesting monograph on Sophocles and Pericles has argued strongly for an element of subtle political commentary in the treatment of Oedipus in the Oedipus Tyrannus , and of Pocreon in the Antigone. These remarks may serve to show that the title does not express a blind indifference to the multiple complexity of those works which we class together as tragedies. They are inherently complex, and various in emphasis; at best we can discern a family resemblance between them, and, in an essay like this, the author runs the risk not only of selecting examples tailor-made to his thesis, but also of imposing an appearance of similarity of conception where it is at least equally important to stress differences.

Breaking new ground in the debate about the relation of mind and body, David Armstrong's classic text - first published in 1968 - remains the most compelling and comprehensive statement of the view that the mind is material or physical. In the preface to this new edition, the author reflects on the book's impact and considers it in the light of subsequent developments. He also provides a bibliography of all the key writings to have appeared in the materialist debate.

This is a study of a crucial and controversial topic in metaphysics and the philosophy of science: the status of the laws of nature. D. M. Armstrong works out clearly and in comprehensive detail a largely original view that laws are relations between properties or universals. The theory is continuous with the views on universals and more generally with the scientific realism that Professor Armstrong has advanced in earlier publications. He begins here by mounting an attack on the orthodox and (...) sceptical view deriving from Hume that laws assert no more than a regularity of coincidence between instances of properties. In doing so he presents what may become the definitive statement of the case against this position. Professor Armstrong then goes on to establish his own theory in a systematic manner defending it against the most likely objections, and extending both it and the related theory of universals to cover functional and statistical laws. This treatment of the subject is refreshingly concise and vivid: it will both stimulate vigorous professional debate and make an excellent student text. (shrink)

According to historical theories of biological function, a trait's function is determined by natural selection in the past. I argue that, in addition to historical functions, ahistorical functions ought to be recognized. I propose a theory of biological function which accommodates both. The function of a trait is the way it contributes to fitness and fitness can only be determined relative to a selective regime. Therefore, the function of a trait can only be specified relative to a selective regime. Apart (...) from its desirable pluralism, only this view of relational function can support the function/accident and function/malfunction distinctions commonly thought to be part of the concept of function. Furthermore, only relational function correctly characterizes the explanatory consequences of function attributions in evolutionary biology. (shrink)

Truths are determined not by what we believe, but by the way the world is. Or so realists about truth believe. Philosophers call such theories correspondence theories of truth. Truthmaking theory, which now has many adherents among contemporary philosophers, is the most recent development of a realist theory of truth, and in this book D. M. Armstrong offers the first full-length study of this theory. He examines its applications to different sorts of truth, including contingent truths, modal truths, truths about (...) the past and the future, and mathematical truths. In a clear, even-handed and non-technical discussion he makes a compelling case for truthmaking and its importance in philosophy. His book marks a significant contribution to the debate and will be of interest to a wide range of readers working in analytical philosophy. (shrink)
