This article examines the diversity of food networks that fit within the alternative food system of the United States. While farmers’ markets, community supported agriculture schemes, and corporate organic food markets all fit within the alternative food system, they differ greatly in the conventions and beliefs that they represent. The alternative food system has divided into two movements: corporate, weak alternative food networks; and local, strong alternative food networks. The weak corporate version focuses on protecting the environment; however, it neglects (...) issues concerning labor standards, animal welfare, rural communities, small-scale farmers, and human health. Local, strong alternative food networks not only assure environmental protection, but they also address the issues that weak alternatives neglect. Using three case studies from the Washington, D.C. metro area, the author explains that strong alternative food networks are better suited to create social and political change because they challenge the foundations of the conventional food system: standardized and generic products, price-based competition, consolidated power, and global scale. To affect true social and political change in the United States, the author recommends supporting strong alternative food networks by creating the requisite cultural and political space for them to succeed.

The historical evolution of the homotopy concept for paths illustrates how the introduction of a concept (be it implicit or explicit) depends upon the interests of the mathematicians concerned and how it gradually acquires a more satisfactory definition. In our case the equivalence of paths first meant for certain mathematicians that they led to the same value of the integral of a given function or that they led to the same value of a multiple-valued function. (See for instance [Cau], [Pui], (...) [Rie].) Later this dependency upon given functions is dropped (by Jordan for surfaces, by Riemann and most explictly by Poincaré) and this leads to a concept which depends only upon the manifold. It thus becomes a concept which belongs to topology. As a consequence of this hesitant evolution, there was at first a confusion between concepts and hence no attention to relations between them. At a later stage these relations were investigated, as for instance the fact that homotopy equivalence implies homology equivalence: in1882, Klein gave an example of a closed curve on a surface which is the boundary of a part of the surface but could not be shrunk to a point. In 1904, Poincaré explicitly said that this curve is “homologue à zéro” (null homologous), but not “équivalent à zéro” (null homotopic). Poincaré obtains the homologies from the fundamental group by allowing changes in the order of the terms in the “équivalences”. This means also that the equivalences imply homologies but not vice versa. From a methodological standpoint, this situation of using properties without asking about relations between them or without even properly defining them is reminiscent of mathematics of a century earlier. An example is the way differentiability was used for the differentiation of functions without consciously questioning the properties of this concept until in the nineteenth century examples were given by Bolzano (1834), Weierstrass (1872), Riemann (1854) and others of functions which are continuous but nowhere differentiable [Kli]. Another example is the use eighteenth-century mathematicians made of series without inquiring about the validity of the operations they used on them. Another aspect which had its influence was the success of algebraic methods in topology which explains the preference for theories with “base point” and constrained deformation even though free deformation is a more natural concept. As we can see the evolution of the homotopy concept for paths did not progress without impediments. It also had an influence on the evolution of the abstract group concept and the basic principle of equivalence. These aspects make it a history which is not only intrinsically interesting (how did homotopic paths come to be?), but also because it illustrates relations between different branches of mathematics.

In lieu of an abstract, here is a brief excerpt of the content:284 HISTORY OF PHILOSOPHY Although this is not the first time that Gentile has been translated into French (a major work of his, L'esprit, acte pur, was published in Paris in 1925), the fact remains nevertheless that his neo-Hegelian system of philosophy fell on deaf ears originally in France, due to the predominance then of Bergsonism and positivi.sm in different areas of French thought. However, as Michele F. Sciacca (...) (another commentator on Gentile) notes in the Preface, the Gentilian system of "actual idealism" should get a better hearing in France from now on, because the widespread interest in Hegel there since 1925 has prepared the ground for its proper reception. The Bibliography, for which Sciacca himself is responsible, includes a section on Gentile's own writings "concerning the national and political formation of Italy" (p. 14); but, significantly enough, those dealing directly with Fascism are all omitted. This omission seems a deliberate attempt to separate Gentile the philosopher from Gentile the Fascist. No matter how understandable psychologically and politically may be the motive here--to have French readers forget that Gentile was the philosopher of Fascism--the attempt itself at bibliographical expurgation, ironically, runs completely counter to the very accent of the Gentilian theory of "pure act" on the unity of thought and action in human experience and history. Rightly or wrongly, Gentile (in sharp contrast to Croce) saw in Fascism the political expression of that unity. As to the secondary sources, the Bibliography again is unnecessarily incomplete, citing as it does only one work in English on Gentile. The anthology closes with a critical note on Gentile's transcendental conception of immortality by the translator (Joseph Moreau), who argues that the "actualistic" philosophy, despite its "religious tone," defeats itself by ending up with an "Epicurean attitude" (p. 324) toward death and the afterlife. PATRICK ROMANELL University o/ Oklahoma Die Tragik in der Existenz des modernen Menschen bei G. Sirnmel. By Isadora Bauer. (Berlin: Duncker und Humblot, 1962. Pp. 94. DM 12.60.) Miss Isadora Bauer's book lends a salutory touch to contemporary philosophical literature, so much of which is abstract and removed from experience. Her treatise, on the other hand, has for its subject matter the human condition, its finitude, and its inescapable tragedy. Georg Simmel, an early twentieth-century philosopher, is less known in this country than he deserves to be. His "Lebensphilosophie," as Miss Bauer points out, although it was influenced by Schopenhauer and Nietzsche, found an original expression through him and foreshadowed in many ways the work of Husserl and the contemporary existential thinkers. Miss Bauer's presentation of Simmel's concept of the tragic is lucid and thorough and manages in a wonderful way to let us see through this one aspect the broad outlines of Simmel 's philosophy as a whole. In Simmel's formulation, life itself, unfolding in tragic antinomy of flux and form, of becoming and being, is the ultimate ground of all tragic conflict. The dynamic life process brings forth all forms and also endangers and destroys them over and over again. The human being encounters these opposites in all aspects of his experience: his existence is tragic at its core. "Moira," the ancient goddess who confronted the Greek hero as an alien power, is in Simmel's modern view of tragedy within man himself. She is the opposition between continuity and discontinuity, the mere stream of events and their form or meaning broken in tragic conflict. At this point, Simmel's dialectics leads to a "third realm," a "more BOOK REVIEWS 285 than" which is both immanent and transcendent, a kind of "coincidentia oppositorum" beyond logic and definition. It is the realm of the "person" within which, although the tragic conflict is not resolved, there arises the free self from whose non-dual perspective the unity and eternity of life are seen. Within this realm the individual gains an illumination the result of which is "amor fad," his free decision to affirm his being. In this act of decision lies the "meaning" and "value" of life. The substance and point of Miss Bauer's book is to show the connection between the metaphysical ground of Simmel... (shrink)

The network approach to psychopathology posits that mental disorders can be conceptualized and studied as causal systems of mutually reinforcing symptoms. This approach, first posited in 2008, has grown substantially over the past decade and is now a full-fledged area of psychiatric research. In this article, we provide an overview and critical analysis of 363 articles produced in the first decade of this research program, with a focus on key theoretical, methodological, and empirical contributions. In addition, we turn our attention (...) to the next decade of the network approach and propose critical avenues for future research in each of these domains. We argue that this program of research will be best served by working toward two overarching aims: (a) the identification of robust empirical phenomena and (b) the development of formal theories that can explain those phenomena. We recommend specific steps forward within this broad framework and argue that these steps are necessary if the network approach is to develop into a progressive program of research capable of producing a cumulative body of knowledge about how specific mental disorders operate as causal systems.

In lieu of an abstract, here is a brief excerpt of the content:116 HISTORY OF PHILOSOPHY Der Begriff des Lebens bei Plotin. By Grigorios Ph. Kostaras. (Hamburg: Felix Meiner Verlag, 1969. Pp. ix+139. DM 36) In his excellent book, The Concept of Life in Plotinus, Mr. Grigorios Ph. Kostaras presents the thesis that it is the problem of life which lies at the center of the thought of Plotinus, that it permeates it in its entirety and that he views all (...) other philosophical problems from its perspective. The two main metaphysical questions of Greek philosophy, "Why is there something rather than nothing?" and "What then is man?" appear in a new light when seen from this central concept. The result is a universe which is like a living organism, a unity in its multiplicity whose many forms of life are held together by one life principle, the soul. Human life, the human soul is part of this organism and therefore able to find in it its greatest bliss. The soul, for Plotinus, is the necessary condition that there be life. It is the ground of all macrocosmic and microcosmic entities, being essentially movement, it is the creative and formgiving principle of all that is, it is the law of life. The reduction of the many to the one seemed to Plotinus a logical necessity if man is to grasp the origin and continuity of the cosmos. His new reality, "The One," fills this logical need. Out of its perfection and fullness emanates Mind (Nous) "like light from the sun." This gives rise to the soul as its logos and substance. The physical universe is the result of the soul's movement towards "the Other," matter on which it imprints the forms of the intelligible world.thus shaping and ordering the world as we know it. In this activiO/ the soul remains one and whole; the "many," the concrete life forms of reproduction and perception appear as a result of its relation to matter. What makes for this creative, formgiving activity which is its movement away from the One and lqous, from identity towards diversity, from eternity to time? The Plotinian answer, as Mr. Kostaras sees it, is both exuberant and tragic. The soul becomes the shaper of all there is through its striving towards freedom and independence and its joy in the manifold appearances which its relation to matter brings about. The soul's biological movement then is an affirmation and celebration of temporal life as one of its manifestations. Yet, at the same time, this movement is unfree since it follows a need the soul cannot avoid. Thus it means estrangement from its true life of the logos. The soul is isolated and "sick" of which the incessant movement of becoming, of changing from one form of life to another is the result. It leads a negative or pseudo life. Suffering, then, must be inextricably joined to the beauty of temporal life. True life, therefore, is the life of the mind. It is life as the soul's movement toward itself rather than the outer world, life become conscious of itself, leading out of the sensible world, back to identity with Nous and ultimately with the One. In this, its highest movement, the soul severs itself from time. In it there is no past nor future but an eternal Now, no moving image but reality itself. Such is the ground and explanation of the universe, the metaphysical framework within which man may choose his being. As microcosm within the macrocosm, he is a composite of Nous, soul-substance and bodily nature. The relation between these three principles forms the ground of human life; the manner in which man chooses to link them to one another makes for the differences between the modes of life of human beings. The movement of the human soul towards the outer world and its absorption in becoming means the realization of man as bodily being only. His life is ruled by perceptions and the beliefs based upon them. His feelings are uncontrolled, his mind inactive. He lives the life of the fleeting moment, a mere shadow of its reality. Just as the soul or life principle of the cosmos links the intelligible to the sensible... (shrink)

This article discusses the origins, spiritual aspects, and development of Mahaputra Pencak Silat in Cintaraja village, Singaparna subdistrict. The main focus includes analysis of martial arts training which teaches how learners control their desires and impulses, as well as emphasizing the importance of self-defense in the life of a soldier. The research method was evaluated based on a historical and sociological approach where the discussion of the object was based on society and related to existing facts in Cintaraja village which (...) were collected through observation, appropriate questionnaires and existing documentation. The results of the training process for the "Bender" style begin with prayers to the Creator, the ancestors, and martial arts teachers from the eight cardinal directions. This series of prayers symbolizes spiritual practice in starting training and is also an effort to defend oneself (manage one's readiness) so that one can master the techniques being learned. The ritual behavior process applied to students is adapted from daily behavior according to the era or period. The impact felt by the learner gives rise to behavior related to self-defense. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

In this volume, we suggest new perspectives with which critical animal studies (CAS) can contribute to the development of knowledge and praxis in two fields-dehumanization and critical border studies, both concerned with human migration, refuge, and territorial or other borders. CAS is an interdisciplinary field that reflects on the ethics of humans' relationships with other animals, how the oppression of nonhuman animals intersects with other forms of oppression, and how economic interests drive oppression. CAS scholars reject disinterested analysis to champion (...) liberation for human animals, nonhuman animals, and the Earth. (shrink)

O mundo contemporâneo é o do exílio e não o da pátria, o da errância e não o do lugar. Razão pela qual nosso tempo foi denominado de “século breve”, em que os acontecimentos e os desaparecimentos de modos de vida e valores são acelerados, não permitindo o repouso para constituição de uma memória reparadora. Exílio, expatriamento e dispersão espacial são, pois, o emblema das migrações forçadas por guerras, perseguições políticas e diferentes formas de conflito, que produzem a “nostalgia do (...) inteiramente outro” diante da “vida mutilada”. Assim, a diferença entre duas figuras: a da viagem e a da partida, a odisseia e o êxodo, uma que vive no horizonte de um retorno, outra que anseia por uma pátria que não existe mais. A viagem contemporânea para uma terra de exílio tem algo de enigmático, pois populações inteiras atravessam os mares, assombradas pelos naufrágios e pela incerteza da chegada ou do encontro de um não lugar. Herdeiro problemático de um duplo trauma – o do extermínio dos judeus europeus durante o nazismo e, simultaneamente, o da expulsão dos palestinos de sua terra com a criação do Estado de Israel – Edward Saïd, um dos mais importantes intelectuais palestinos, refletiu sobre a questão da identidade em situações de exílio e estranhamento cultural, procedendo a uma genealogia do sentimento de desorientação, desrealização e perda de si que o exílio produz. Pois se, antes, cada um de nós tem o conforto de paisagens conhecidas, o aconchego do mundo entre os seus, o país estrangeiro representa a passagem do conhecido ao desconhecido, significa o enfrentamento de um incerto acolhimento, com incompreensões, desprezo e hostilidade do lugar a que se chegou. Reunindo, assim, sua formação de scholar em literatura nos Estados Unidos e de musicólogo e pensador geopolítico, Edward Saïd refletiu sobre a construção de um Oriente pelo Ocidente, pelo medium de escritores nos quais há a personagem fantasmada do Outro.
