Homegardens are traditional food systems that have been adapted over generations to fit local cultural and ecological conditions. They provide a year-round diversity of nutritious foods for smallholder farming communities in many regions of the tropics and subtropics. In southwestern Uganda, homegardens are the primary source of food, providing a diverse diet for rural marginalized poor. However, national agricultural development plans as well as economic and social pressures threaten the functioning of these homegardens. The implications of these threats are difficult (...) to evaluate, because the structure and functions of the homegardens are not well understood. The aim of the study was to identify patterns and influencing factors in the diversity of homegardens by documenting the floristic diversity and its interactions with spatial, environmental and socio-economic factors. A geographically and socially focused assessment of floristic diversity in 102 randomly selected homegardens in three districts of southwest Uganda was conducted along a deforestation gradient following a human ecology conceptual framework and testing multiple quantitative hypotheses regarding the above mentioned factors. A merged mixed-method approach was followed to provide context and feedback regarding quantitative findings. Results show a high total richness of 209 crop species dominated by food species, which constituted 96 percent of individuals and 44 percent of all species. Forest-edge homegardens maintained higher plant diversity compared to homegardens in deforested areas and near degraded wetlands. Multiple linear regression models indicated elevation, location, homegarden size, distance to market, additional land ownership and livestock ownership as significant predictors of crop diversity. Cluster analysis of species densities revealed four garden types: ‘diverse tree gardens’, ‘small forest-edge gardens’, ‘large, old, species-rich gardens’, and ‘large, annual-dominated herb gardens’, with 98% correct classification. Location, elevation, and garden size were also important determinants in the cluster assignment. We conclude that the diversity of the studied homegardens may be changing as part of adaptive traditional practices and in response to external drivers. The identified patterns illustrate the importance of homegardens for rural livelihoods and may offer some ways to support farmers to maintain these systems as relevant mechanisms for development in Uganda.

Though virtually unknown before 1851, the exceptionally scenic Yosemite Valley of California soon attracted continuing attention as a geological anomaly. J. D. Whitney, state geologist and Harvard professor, advocated a tectonic theory of its origin. Despite its seemingly official status, Whitney's theory even failed to convince some of his own subordinates. An unexpectedly effective dissenter not associated with Whitney was John Muir, then a tatterdemalion vagrant. Though the two men never met, conflict between their inflexible and (...) mutually exclusive geological theories persisted well into the twentieth century. Eventually, both dogmatists were proved wrong, but Muir had come closer to what we now accept. Several geological and geomorphological issues of importance entered into later discussions of Yosemite. The whole controversy, moreover, illuminates such further issues as the influence of preconceptions on theorizing, the role of authority in science, and the interactions of professionals with amateurs.

Recent reports of the discovery of a “God module” in the human brain derive from the fact that epileptic seizures in the left temporal lobe are associated with ecstatic feelings sometimes described as an experience of the presence of God. The brain area involved has been described as either (a) the seat of an innate human faculty for experiencing the divine or (b) the seat of religious delusions.In fact, religious experience is extremely various and involves many parts of the brain, (...) including some that are prehuman in their evolutionary history and some that are characteristically human. In the continuing integration of such experiences, spiritual formation takes place. Thus the entire human brain might be described as a “God module.”Such a process is only possible because of the brain's complexity. The human brain is the most complex entity for its size that we know of. As used here, complexity is a specialized term denoting the presence of a web of interlinked and significant connections—the more intricate the web, the more complex the entity. Complex systems develop only in a milieu that provides both lawfulness and freedom, and they tend to be self‐organizing, becoming more complex and more effective as a result of both inward and outward experience. The evidence suggests that both personal growth and spiritual growth are processes of complexification of character, and of the brain itself. This thesis is tested in light of the work of William James and James W. Fowler. (shrink)

It has been suggested that the difference between misremembering (Orwellian) and misrepresentation (Stalinesque) models of consciousness cannot be differentiated (Dennett, 1991). According to an Orwellian account a briefly presented stimulus is seen and then forgotten; whereas, by a Stalinesque account it is never seen. At the same time, Dennett suggested a method for assessing whether an individual is conscious of something. An experiment was conducted which used the suggested method for assessing consciousness to look at Stalinesque and Orwellian distinctions. A (...) visual illusion, illusory line motion, was presented and participants were requested to make judgments that reflected what they were aware of. The participants were able to make responses indicating that they were aware of the actual stimulus in some conditions, but only of the illusion in others. This finding supports a claim that the difference between the Orwellian and Stalinesque accounts may be empirically observable, and that both types of events may occur depending on task and stimulus parameters.

In a recent paper, a “distance” function, $\cal D$ , was defined which measures the distance between pure classical and quantum systems. In this work, we present a new definition of a “distance”, D, which measures the distance between either pure or impure classical and quantum states. We also compare the new distance formula with the previous formula, when the latter is applicable. To illustrate these distances, we have used 2 × 2 matrix examples and two-dimensional vectors for simplicity and (...) clarity. Several specific examples are calculated. (shrink)

The paper explores the handling of singular analogy in quantitative inductive logics. It concentrates on two analogical patterns coextensive with the traditional argument from analogy: perfect and imperfect analogy. Each is examined within Carnap’s λ-continuum, Carnap’s and Stegmüller’s λ-η continuum, Carnap’s Basic System, Hintikka’s α-λ continuum, and Hintikka’s and Niiniluoto’s K-dimensional system. Itis argued that these logics handle perfect analogies with ease, and that imperfect analogies, while unmanageable in some logics, are quite manageable in others. The paper concludes with a (...) modification of the K-dimensional system that synthesizes independent proposals by Kuipers and Niiniluoto. (shrink)

Deals with one of the most critical business issues of the century, the question of corporate responsibility. The author reconstructs and critically evaluates the arguments for the maximisation of profits, versus those to be found in the broader context of increased social responsibility.

This paper addresses what some view as a progressive and decades-long devaluing of the liberal arts in our educational institutions and society at large. It draws attention to symptoms of this trend and possible contributing factors, identifies benefits commonly attributed to the liberal arts, and then shows how insights from recent research on neuroplasticity provide good reason to believe that a traditional liberal education has positive effects on a person's brain. The paper supports the thesis that well-designed liberal arts courses (...) can literally transform students' minds and lives as a result of unique and synergistic brain processes activated and strengthened by the leaming experiences such courses provide. It finishes with recommendations to help reinvigorate and promote the value of liberal education. (shrink)

The problem of a relativistic spin-1/2 particle scattering from a step potential is solved within the theoretical framework of relativistic dynamics. This treatment avoids the Klein paradox. An experiment for testing the theory is suggested.

If one cannot establish givens, such as Platonic ideas, or determiners, such as Kantian categories, as a point of departure for philosophical inquiry, then how is philosophical inquiry to proceed in a non-question-begging manner? This, of course, is the familiar problem of grounding philosophical discourse. In this essay, I hope to offer a Zhuangzian solution—that is, a solution derived from analysis of the Zhuangzi 莊子 text—to this perennial philosophical problem. As a result, I hope to give the reader a critical (...) glimpse into a Zhuangzian philosophy without foundations, thereby providing a potential solution to the preceding problem while displaying the continued relevance of the Zhuangzi text.

Technologies can range from the simplest of shelters to keep us warm and dry, to the most complex bioengineering interventions. In this technologically mediated world we now inhabit, there is a growing need for human beings, and particularly young people, to be more critically involved in the discourse surrounding technology. In order to achieve a truly democratic world, any tensions or confusions between human beings, their environment, and their technologies must be resolved. Only then will people become empowered to improve (...) their world in a creative, sensitive, informed and above all, sustainable fashion. This collection offers a solid basis for defining this new technological literacy by bringing together theoretical work that ranges from philosophy, design, and pedagogy. (shrink)

The experimental confirmation of nonlocality has renewed interest in Bohm's quantum potential. The construction of quantum potentials for relativistic systems has encountered difficulties which do not arise in a parametrized formulation of relativistic quantum mechanics known as Relativistic Dynamics. The purpose of this paper is to show how to construct a quantum potential in the relativistic domain by deriving a relativistically invariant quantum potential using Relativistic Dynamics. The formalism is applied to three relativistic scalar particle models: a single particle interacting (...) with a scalar potential; N particles interacting with a scalar potential; and a single particle interacting with an electromagnetic 4-vector potential.

Since ought implies can, i.e., one cannot be obligated to do what one cannot do, the question of corporate responsibility cannot be discussed intelligibly without an inquiry into the range of corporate or managerial discretion. Hence, the moral relevance of a theory of the firm. Within classical or neo-classical economic theory, for instance, firms which act other than to maximize profit are eliminated. They cannot do otherwise, and thus either have no obligations at all or only the duty to maximize (...) profit. The thesis of the Managerial Revolution, if true, establishes only that management is free from direct stockholder control. By asserting that corporations have responsibilities to do other than maximize profit, philosophers assume a wide degree of managerial discretion, without considering recent developments in the theory of the firm which suggest that new incentives and constraints radically restrict managerial liberty in a capitalist society.

Analyzing Zhuangzi’s Wild Card as presented by Brook Ziporyn, this essay aims (1) to clarify and draw out certain implications of Zhuangzi’s epistemological agnosticism and perspectivism (qua Ziporyn’s reading thereof), only (2) to problematize Zhuangzi’s response to this epistemological agnosticism and perspectivism (qua Ziporyn’s reading thereof). In turn, given the success of my argumentation, Zhuangzi will prove to be as pertinent (and unsettling) as ever.

Transcendental theology is, as a return to the subject, an attempt to take experience seriously, because transcendental method explores the full range of the conditions of the possibility of experience. For Rahner, transcendental theology is theological anthropology. This study explores his method also in relation to transcendental experience of God.

Throughout much of this century the most prominent exegetes maintained that Aquinas’s mature moral psychology is fundamentally voluntarist, that he considers the will an independent cause of action, most conspicuously in his later works. Disagreement over the character of the will’s causal authority and the composition of the list of later works did little to unsettle their shared conviction that Aristotle’s intellectualist moral psychology was improved, indeed saved, by Aquinas’s insistence that the will can move itself, at least in some (...) fashion, apart from the influence of the intellect.

Recent experiments have renewed interest in nonlocal interpretations of quantum mechanics. The experimental observation of the violation of Bell's inequalities implies the existence of nonlocality. Bohm expressed the nonlocal connection between quantum particles through the wave function and the quantum potential. This paper shows that a similar connection exists in a relativistic dynamical theory known as parametrized relativistic quantum theory (PRQT). We present an introduction to PRQT, derive the quantum potential for a system of relativistic scalar particles, and discuss alternative (...) interpretations of nonlocality. (shrink)

The theoretical description of particle decay by a single particle theory requires the use of a probability density in time that is not present in conventional theories. The problem of single particle decay is consistently described here within the context of a single particle, relativistic dynamical theory. We derive experimentally testable differences between the standard model and Relativistic Dynamics for a two-state system: the neutral K-meson (K 0) system. We show that the estimate of mass difference between the two states (...) is theory dependent. (shrink)

We wish to determine the correct partial differential equation(s) for describing a relativistic particle. A physical foundation is presented for using a parametrized wave equation with the general form $$i\frac{{\partial \psi }}{{\partial s}} = K\psi$$ where s is the invariant evolution parameter. Several forms have been proposed for the generator K of evolution parameter translations. Of the proposed generators, only the generator K 2 which is proportional to the inner product P μ P μ of fourmomentum operators can be derived (...) from first principles, notably a probabilistic basis. Although experimental tests must be made to establish the validity of K 2,we conclude that K 2 is the leading theoretical candidate for the form of a generator of evolution parameter translations.
