Most land plants associate with mycorrhizal fungi that can connect roots of neighboring plants in common mycelial networks (CMNs). Recent evidence shows that CMNs transfer warning signals of pathogen and aphid attack between plants. However, we do not know how defence‐related signaling via CMNs operates or how ubiquitous it is. Nor do we know what the ecological relevance and fitness consequences are, particularly from the perspective of the mycorrhizal fungus. Here, we focus on the potential fitness benefits for mycorrhizal fungi (...) and outline hypothetical scenarios in which signal transfer via CMNs is modulated in order to acquire the most benefit for the fungus (i.e. acquisition of carbon) for minimal cost. We speculate that the signal may be quantitative and may elicit plant defence responses on different levels depending on the distance the signal is transferred. Finally, we discuss the possibility of practical applications of this phenomenon for crop protection. (shrink)

The purpose of this study is to assess the relationship between involvement in three aspects of congregational life and spiritual growth. In addition, an effort is made to see if spiritual growth may, in turn, affect health. A latent variable model was developed to test the following hypotheses: individuals who attend worship services more often, attend Bible study and prayer group meetings more frequently, and individuals who receive more spiritual support from fellow church members will be more likely to report (...) they have experienced spiritual growth; people who experience more spiritual growth will be more likely to derive a deeper sense of meaning in life; and individuals who have developed a deeper sense of meaning in life will enjoy better health. Data from the U.S. Congregational Life Survey suggests that spiritual support has the stronger relationship with spiritual growth than either worship service attendance or involvement in formal church groups. The findings further reveal that greater spiritual growth is associated with a deeper sense of meaning in life and meaning, in turn, is associated with better health. (shrink)

Plato's Affinity Argument for the Immortality of the Soul DAVID APOLLONI VROM Phaedo 78b to 8od, Socrates attempts to answer Simmias' fear that, even if the soul has existed eternally before birth, it might be dispersed and this would be the end of its existence. His answer is an argument which attempts to show that the soul is incomposite because it is similar to the Forms and dissimilar to physical objects. To date, this argument -- the so-called Aftin- (...) ity Argument -- has not received much sympathy from Plato's commentators, who universally consider it the weakest of Plato's arguments for the immortal- ity of the soul? The lack of sympathy and enthusiasm for this argument is not difficult to understand. Just consider the following outline of the argument. The soul is invisible, therefore the soul is more similar to the Invisible, i.e., the Forms, which are always the same, than are bodies, which are visible and which are constantly changing, and which are more similar to the Visible than is the soul. Further, the soul is more like the Always the Same in that when it uses the body to see or hear or perceive, it is "dragged" by the body into the Never the Same, and the soul "wanders and is confused and whirls as if intoxicated" insofar as the soul has come in contact with such things. Whereas when the soul considers by itself, it goes to the realm of the Forms, and ceases its wandering. Therefore the soul is more like the Always... (shrink)

Plato believes in the existence of Forms—eternal models or exemplars of which objects in our world in time and space are copies, and his Theory of Forms lies at the center of his philosophy. But according to the common wisdom, Plato raised the Third Man objection against his own Theory of Forms in the Parmenides. According to this objection, each Form is supposed to have the very characteristic it is supposed to be , and this leads to an infinite regress (...) of each Form . This book defends the view that a mysterious plural phrase at Phaedo 74 shows that the Self-Predication Assumption is both plausible and leads to no infinite regress of Forms. The Self-Predication Assumption in Plato is an essential resource for scholars, specialists, and students with an interest in ancient philosophy and classics. (shrink)

We trace the history of the Modern Evolutionary Synthesis, and of genetic Darwinism generally, with a view to showing why, even in its current versions, it can no longer serve as a general framework for evolutionary theory. The main reason is empirical. Genetical Darwinism cannot accommodate the role of development (and of genes in development) in many evolutionary processes. We go on to discuss two conceptual issues: whether natural selection can be the “creative factor” in a new, more general framework (...) for evolutionary theorizing; and whether in such a framework organisms must be conceived as self-organizing systems embedded in self-organizing ecological systems.

Using the evolution of the stickleback family of subarctic fish as a touchstone, we explore the effect of new discoveries about regulatory genetics, developmental plasticity, and epigenetic inheritance on the conceptual foundations of the Modern Evolutionary Synthesis. Identifying the creativity of natural selection as the hallmark of the Modern Synthesis, we show that since its inception its adherents have pursued a variety of research projects that at first seemed to conflict with its principles, but were accommodated. We situate challenges coming (...) from developmental biology in a dialectic between innovation and tradition, suggesting on the basis of past episodes that even if developmental plasticity and epigenetic inheritance are aligned with its principles the Modern Synthesis will be significantly affected.

Since his death in 1997, Isaiah Berlin's writings have generated continual interest among scholars and educated readers, especially in regard to his ideas about liberalism, value pluralism, and "positive" and "negative" liberty. Most books on Berlin have examined his general political theory, but this volume uses a contemporary perspective to focus specifically on his ideas about freedom and liberty. Isaiah Berlin and the Politics of Freedom brings together an integrated collection of essays by noted and emerging political theorists that commemorate (...) in a critical spirit the recent 50th anniversary of Isaiah Berlin's famous lecture and essay, "Two Concepts of Liberty." The contributors use Berlin's essay as an occasion to rethink the larger politics of freedom from a twenty-first century standpoint, bringing Berlin's ideas into conversation with current political problems and perspectives rooted in postcolonial theory, feminist theory, democratic theory, and critical social theory. The editors begin by surveying the influence of Berlin's essay and the range of debates about freedom that it has inspired. Contributors' chapters then offer various analyses such as competing ways to contextualize Berlin's essay, how to reconsider Berlin's ideas in light of struggles over national self-determination, European colonialism, and racism, and how to view Berlin's controversial distinction between so-called "negative liberty" and "positive liberty." By relating Berlin's thinking about freedom to competing contemporary views of the politics of freedom, this book will be significant for both scholars of Berlin as well as people who are interested in larger debates about the meaning and conditions of freedom.

Social movements are using education to generate critical consciousness regarding the social and environmental unsustainability of the current food system, and advocate for agroecological production. In this article, we explore results from a cross-case analysis of six social movements that are using education as a strategy to advance food sovereignty. We conducted participatory research with diverse rural and urban social movements in the United States, Brazil, Cuba, Bolivia, and Mexico, which are each educating for food sovereignty. We synthesize insights from (...) critical food systems education and the political ecology of education in analyzing these cases. We compare the thematic similarities and difference between these movements’ education initiatives in terms of their emergence, initial goals, expansion and institutionalization, relationship to the state, theoretical inspirations, pedagogical approach, educational topics, approach to student research, and outcomes. Among these thematic areas, we find that student-centered research on competing forms of production is an integral way to advance critical consciousness about the food system and the political potential of agroecological alternatives. However, what counts, as success in these programs, is highly case-dependent. For engaged scholars committed to advancing education for food sovereignty, it is essential to reflect upon the lessons learned and challenges faced by these movements. (shrink)

"The Bush administration and Congress are in concert on the goal of developing a fleet of unmanned aircraft that can reduce both defense costs and aircrew losses in combat by taking on at least the most dangerous combat missions. Unmanned combat aerial vehicles (UCAVs) will be neither inexpensive enough to be readily expendable nor-- at least in early development-- capable of performing every combat mission alongside or in lieu of manned sorties. Yet the tremendous potential of such systems is widely (...) recognized, and allies as well as potential adversaries are moving quickly to mount their own research and development programs. The United States is committed to fielding UCAV capabilities by 2010, principally for the missions of suppression of enemy air defense and deep strike, which are among the highest risk tasks for the Air Force and naval aviation."--Overview.

The Darwinian concept of natural selection was conceived within a set of Newtonian background assumptions about systems dynamics. Mendelian genetics at first did not sit well with the gradualist assumptions of the Darwinian theory. Eventually, however, Mendelism and Darwinism were fused by reformulating natural selection in statistical terms. This reflected a shift to a more probabilistic set of background assumptions based upon Boltzmannian systems dynamics. Recent developments in molecular genetics and paleontology have put pressure on Darwinism once again. Current work (...) on self-organizing systems may provide a stimulus not only for increased problem solving within the Darwinian tradition, especially with respect to origins of life, developmental genetics, phylogenetic pattern, and energy-flow ecology, but for deeper understanding of the very phenomenon of natural selection itself. Since self-organizational phenomena depend deeply on stochastic processes, self-organizational systems dynamics advance the probability revolution. In our view, natural selection is an emergent phenomenon of physical and chemical selection. These developments suggest that natural selection may be grounded in physical law more deeply than is allowed by advocates of the autonomy of biology, while still making it possible to deny, with autonomists, that evolutionary explanations can be modeled in terms of a deductive relationship between laws and cases. We explore the relationship between, chance, self-organization, and selection as sources of order in biological systems in order to make these points. (shrink)

Research indicates that greater involvement in religion may be associated with better physical health. The purpose of this study is to see if the satisfaction of spiritual needs is associated with health. This model that contains the following core hypotheses: Individuals who attend church more often are more likely to receive spiritual support from fellow church members than people who attend worship services less frequently ; receiving more spiritual support is associated with stronger feelings of belonging in a congregation; individuals (...) who feel they belong in their congregations are more likely to feel their spiritual needs have been met; and people who feel their spiritual needs have been met are more likely to rate their health in a favorable manner. The data provide support for each of these relationships. (shrink)

Barresi & Moore provide an impressive account of how the coordination of first and third person information about the self and other could produce an account of intentional relations. They are less explicit as to how the child comes to understand the basic epistemic relation between experience and knowledge, that is, how informational access causes belief. We suggest one route.

In this essay, Bruce Maxwell, David Waddington, Kevin McDonough, Andrée-Anne Cormier, and Marina Schwimmer compare two competing approaches to social integration policy, Multiculturalism and Interculturalism, from the perspective of the issue of the state funding and regulation of conservative religious schools. After identifying the key differences between Interculturalism and Multiculturalism, as well as their many similarities, the authors present an explanatory analysis of this intractable policy challenge. Conservative religious schooling, they argue, tests a conceptual tension inherent in Multiculturalism (...) between respect for group diversity and autonomy, on the one hand, and the ideal of intercultural citizenship, on the other. Taking as a case study Québec's education system and, in particular, recent curricular innovations aimed at helping young people acquire the capabilities of intercultural citizenship, the authors illustrate how Interculturalism signals a compelling way forward in the effort to overcome the political dilemma of conservative religious schooling.

For over a century, the Danish thinker Søren Kierkegaard has been at the center of a number of important discussions, concerning not only philosophy and theology, but also, more recently, fields such as social thought, psychology, and contemporary aesthetics, especially literary theory. Despite his relatively short life, Kierkegaard was an extraordinarily prolific writer, as attested to by the 26-volume Princeton University Press edition of all of his published writings. But Kierkegaard left behind nearly as much unpublished writing, most of which (...) consists of what are called his "journals and notebooks." Kierkegaard has long been recognized as one of history's great journal keepers, but only rather small portions of his journals and notebooks are what we usually understand by the term "diaries." By far the greater part of Kierkegaard's journals and notebooks consists of reflections on a myriad of subjects--philosophical, religious, political, personal. Studying his journals and notebooks takes us into his workshop, where we can see his entire universe of thought. We can witness the genesis of his published works, to be sure--but we can also see whole galaxies of concepts, new insights, and fragments, large and small, of partially completed but unpublished works. Kierkegaard's Journals and Notebooks enables us to see the thinker in dialogue with his times and with himself. Volume 6 of this 11-volume series includes four of Kierkegaard's important "NB" journals, covering the months from early May 1849 to the beginning of 1850. At this time Denmark was coming to terms with the 1848 revolution that had replaced absolutism with popular sovereignty, while the war with the German states continued, and the country pondered exactly what replacing the old State Church with the Danish People's Church would mean. In these journals Kierkegaard reflects at length on political and, especially, on ecclesiastical developments. His brooding over the ongoing effects of his fight with the satirical journal Corsair continues, and he also examines and re-examines the broader personal and religious significance of his broken engagement with Regine Olsen. These journals also contain reflections by Kierkegaard on a number of his most important works, including the two works written under his "new" pseudonym Anti-Climacus and his various attempts at autobiographical explanations of his work. And, all the while, the drumbeat of his radical critique of "Christendom" continues and escalates. Kierkegaard wrote his journals in a two-column format, one for his initial entries and the second for the extensive marginal comments that he added later. This edition of the journals reproduces this format, includes several photographs of original manuscript pages, and contains extensive scholarly commentary on the various entries and on the history of the manuscripts being reproduced.
