Several scholars have claimed that small-scale agriculture in which farmers sell goods to the local market has the potential to strengthen social ties and a sense of community, a phenomenon referred to as “civic agriculture.” Proponents see promise in the increase in the number of community supported agriculture programs, farmers markets, and other locally orientated distribution systems as well as the growing interest among consumers for buying locally produced goods. Yet others have suggested that these novel or reborn distribution mechanisms (...) are still primarily means of instrumental economic exchange and that optimistic characterizations of a renewed sense of community emerging from these practices are unfounded. This study provides an empirical assessment of the extent to which these community-based agriculture markets are associated with connection to community, volunteerism, and civic and political activities. In order to assess the relationship between civic agriculture and community engagement, we surveyed over 1,300 people in the Mid-Hudson region of New York State. The study design includes “civic agriculture participants” as the unit of analysis, defined as CSA farm members, shoppers at independent health food stores, and farmers market patrons. For comparison, a telephone survey of randomly selected residents of the region’s general population was also conducted. Unlike studies that focus solely on the perceptions of certain civic agriculture participants, by comparing the perceptions and behaviors of those engaged in a range of civic agriculture practices, we are able to identify the effects of different forms of participation. The results demonstrate higher levels of voluntarism and engagement in local politics among civic agriculture participants relative to the general population. In addition, we found variation among those engaged in different forms of civic agriculture, with those immersed in more socially embedded forms of exchange demonstrating greater community and political involvement. These findings lend empirical support to the civic agriculture thesis. (shrink)

Our aim in this paper is to take quite seriously Heinz Post’s claim that the non-individuality and the indiscernibility of quantum objects should be introduced right at the start, and not made a posteriori by introducing symmetry conditions. Using a different mathematical framework, namely, quasi-set theory, we avoid working within a label-tensor-product-vector-space-formalism, to use Redhead and Teller’s words, and get a more intuitive way of dealing with the formalism of quantum mechanics, although the underlying logic should be modified. We build (...) a vector space with inner product, the Q-space, using the non-classical part of quasi-set theory, to deal with indistinguishable elements. Vectors in Q-space refer only to occupation numbers and permutation operators act as the identity operator on them, reflecting in the formalism the fact of unobservability of permutations. Thus, this paper can be regarded as a tentative to follow and enlarge Heinsenberg’s suggestion that new phenomena require the formation of a new “closed” (that is, axiomatic) theory, coping also with the physical theory’s underlying logic and mathematics.

The concept of individuality in quantum mechanics shows radical differences from the concept of individuality in classical physics, as E. Schrödinger pointed out in the early steps of the theory. Regarding this fact, some authors suggested that quantum mechanics does not possess its own language, and therefore, quantum indistinguishability is not incorporated in the theory from the beginning. Nevertheless, it is possible to represent the idea of quantum indistinguishability with a first-order language using quasiset theory (Q). In this work, we (...) show that Q cannot capture one of the most important features of quantum non-individuality, which is the fact that there are quantum systems for which particle number is not well defined. An axiomatic variant of Q, in which quasicardinal is not a primitive concept (for a kind of quasisets called finite quasisets), is also given. This result encourages the searching of theories in which the quasicardinal, being a secondary concept, stands undefined for some quasisets, besides showing explicitly that in a set theory about collections of truly indistinguishable entities, the quasicardinal needs not necessarily be a primitive concept.

In this paper we enrich the orthomodular structure by adding a modal operator, following a physical motivation. A logical system is developed, obtaining algebraic completeness and completeness with respect to a Kripkestyle semantic founded on Baer*-semigroups as in [22].

In beliefs we live, we move and we are [...] the beliefs constitute the base of our life, the land on which we live [...] All our conduct, including the intellectual life, depends on the system of our authentic beliefs. In them [...] lies latent, as implications of whatever specifically we do or we think [...] the man, at heart, is believing or, which is equal, the deepest stratum of our life, the spirit that maintains and carries all the others, (...) is formed by beliefs...We know that the human being is a social animal. This is a common fact. Moreover, the human being is defined as a rational being. It is clear and nobody can deny that human creations include logic, mathematics, philosophy, science, and jurisprudence. These are all products of rationality or abstract thought. Nevertheless, human sociability goes further that the sociability of an animal herd. Societies were founded, cohere, develop, degenerate and die based on their belief systems.

This article reports on ethnographic research into the practical and ethical consequences of the implementation and use of telecare devices for older people living at home in Spain and the United Kingdom. Telecare services are said to allow the maintenance of their users’ autonomy through connectedness, relieving the isolation from which many older people suffer amid rising demands for care. However, engaging with Science and Technology Studies literature on “user configuration” and implementation processes, we argue here that neither services nor (...) users preexist the installation of the service: they are better described as produced along with it. Moving beyond design and appropriation practices, our contribution stresses the importance of installations as specific moments where such emplacements take place. Using Etienne Souriau’s concept of instauration, we describe the ways in which, through installation work, telecare services “bring into existence” their very infrastructure of usership. Hence, both services and telecare users are effects of fulfilling the “felicity conditions” of an achieved installation. (shrink)

Censures au XVIIIe siecle, les ecrivains-philosophes des Lumieres demeurent controverses ou singes de nos jours. Cette etude privilegie leurs idees-forces sans negliger les porte-parole. Celebres (Bayle, Montesquieu, Voltaire, Rousseau, Diderot, Helvetius, d'Holbach...) ou reconnus (d'Argens, Mably, Mirabeau, d'Alembert, Volney, Mme de Stael...) ils n'enferment point leur oeuvre dans le moule d'une pensee unique.

Immoraliste visionnaire, Sade anticipe les derives d'une philosophie deshumanisee. Les debats seculaires avec les apologistes (Abbadie, Barruel, Bergier, Gerard, Holland, Vernes...) elaborent les fondements universels d'une morale non confessionnelle. Du refus des dogmes et de tout esprit de systeme nait une ethique transcendant les revelations. (shrink)

Freezers with biospecimen deposits became biobanks and later were networked at the pan-European level in 2013 under the Biobanking and BioMolecular Resources Research Infrastructure—European Research Infrastructure Consortium (BBMRI-ERIC). Drawing on document analysis about the BBMRI-ERIC and multi-sited fieldwork with biobankers in Spain from a science and technology studies approach, we explore what biobanks are expected to do and become under the BBMRI-ERIC framework, and how infrastructural transitions promote particular transformations in biobanking practices. The primary purpose of biobanks in Europe is (...) presented as being to become mediators in contemporary biomedical research (global sharing nodes) distribution, and distributed nodes of samples and their associated data. We argue that infrastructural transitions are complicated and heterogeneous, giving rise to unattended local concerns on adjusting their practices to fit into the BBMRI-ERIC framework, even for non-members, as the case of Spain illustrates, where “old practices” of collection and storage are questioned. In this article, we aim to encourage qualitative studies to explore the lags between pan-European policies and prospects, different contextual interpretations, and biobanking reconfigurations as an opportunity to explore what that lag is made of (e.g. tensions with “old practices,” unresolved conflicts with the national agendas, reservations on a possible centralization of the biobanking practices by regional biobanks, lack of funding, etc.). Such research could enrich not only policy guidance, but also the understanding of technoscientific infrastructures’ scalability. (shrink)

La fraternidad es el pariente pobre de la tríada democrático-republicana moderna. No sólo políticamente. También filosóficamente: mientras que los conceptos de «igualdad" y "libertad" han sido concienzudamente explorados, "fraternidad», sigue pareciendo una noción amorfa. Este artículo presenta una reivindicación política, a la altura de finales del siglo XX, de la fraternidad, e intenta dibujar filosóficamente, tras un preámbulo histórico, un concepto algo preciso y proteico de ella.

In this paper, the authors attempt to prove there is a relationship between Borges’ “Argumentum ornithologicum” and Anselm’s argument “Argumentum ontologicum”. We suggest Borges, using the image of a flock of birds, with oriental reminiscences, half joking, half serious attempts to prove the existence of God. We demonstrate the fallacies incurred by Borges and why his “Argumentum” has no place within the traditional set of ontological arguments. However, it would easy to forget that Borges’ claim is not philosophical, nor theological, (...) nor apologetic, but rather ironic or paradoxical. (shrink)

In Ontology, quality determines beings. The quality-quantity bipolarity reveals that a conceptual logical comprehension that can include negation must be a dialectical logic. Quality is a precise characteristic of something capable of augmentation or diminution while remaining identical through differences or quantitative changes. Thus, quality and in opposition quantity are inextricably linked, giving definition to each other, so constituting a logical bipolarity. The theory is that a magnitude G is never separated from secondary qualities α and β, and therefore, a (...) measure depends on a concrete quality Gα or Gβ, that is to say on one pole of a logical bi-pole. However, the particular number, the unit, that expresses the result of a measure is the quality G alone. Examples drawn from physical and chemical experiments illustrate these ideas and elaborate the structure of the concept of opposition between the secondary qualities α and β of a magnitude G.

This reply to Gash’s (Found Sci 2014) commentary on Nescolarde-Selva and Usó-Doménech (Found Sci 2014b) answers the questions raised and at the same time opens up new questions.

In the Reality we know, we cannot say if something is infinite whether we are doing Physics, Biology, Sociology or Economics. This means we have to be careful using this concept. Infinite structures do not exist in the physical world as far as we know. So what do mathematicians mean when they assert the existence of ω? There is no universally accepted philosophy of mathematics but the most common belief is that mathematics touches on another worldly absolute truth. Many mathematicians (...) believe that mathematics involves a special perception of an idealized world of absolute truth. This comes in part from the recognition that our knowledge of the physical world is imperfect and falls short of what we can apprehend with mathematical thinking. The objective of this paper is to present an epistemological rather than an historical vision of the mathematical concept of infinity that examines the dialectic between the actual and potential infinity.

In this paper the authors develop a logic of concepts within a mathematical linguistic theory. In the set of concepts defined in a belief system, the order relationship and Boolean algebra of the concepts are considered. This study is designed to obtain a tool, which is the metatheoretical base of this type of theory.

Human language has the characteristic of being open and in some cases polysemic. The word “infinite” is used often in common speech and more frequently in literary language, but rarely with its precise meaning. In this way the concepts can be used in a vague way but an argument can still be structured so that the central idea is understood and is shared with to the partners. At the same time no precise definition is given to the concepts used and (...) each partner makes his own reading of the text based on previous experience and cultural background. In a language dictionary the first meaning of “infinite” agrees with the etymology: what has no end. We apply the word infinite most often and incorrectly as a synonym for “very large” or something that we do not perceive its completion. In this context, the infinite mentioned in dictionaries refers to the idea or notion of the “immeasurably large” although this is open to what the individual’s means by “immeasurably great.” Based on this linguistic imprecision, the authors present a non Cantorian theory of the potential and actual infinite. For this we have introduced a new concept: the homogon that is the whole set that does not fall within the definition of sets established by Cantor. (shrink)

The liar paradox is a famous and ancient paradox related to logic and philosophy. It shows it is perfectly possible to construct sentences that are correct grammatically and semantically but that cannot be true or false in the traditional sense. In this paper the authors show four approaches to interpreting paradoxes that illustrate the influence of: the levels of language, their belonging to indeterminate compatible propositions or indeterminate propositions, being based on universal antinomy and the theory of dialetheism.

Etnicidad e inmigración: ¿Hacia nuevos modos de integración en el espacio escolar?

This paper analyzes the presence of the Fatimid gold coins in al-Andalus and its link with the coinage of the taifa states, through a review of the hoards, from treasures to isolated pieces. This analysis allows to get a full view of the Fatimid gold coinage found in al-Andalus. Also allows to quantify and to establish the extent of the presence of this coinage. The Fatimid gold coinage is frequently treasured next to some taifa issues such as Valencia, Toledo or (...) Zaragoza taifas. This study makes possible to point the historical moment when these coins were hoard. Most of them are from Sicily where they were minted in a moment when the Fatimids had no longer direct control of the island, and where the rubāʽas or quarter dinar predominated. In the Andalusian hoards, most of these coins were fractions of quarter dinar, in spite of the unit dinar that was the gold currency most used in Fatimid Empire. These fractional dinars should have been very valued during the 11th century in al-Andalus because of the quality of his alloy. The rubā‘as coexisted with the fractions of dinar strucked by the taifa kings and were treasured next to them. (shrink)

El artículo explora el proceso de transnacionalización de la política migratoria y la incidencia que ha tenido la emergente perspectiva de la gobernabilidad migratoria en el desarrollo de la “nueva política migratoria” en la Argentina. Se sostiene que su adopción en los organismos del Estado especializados en la migración ha sido decisiva para la configuración de ciertos cambios en los modos de pensar y actuar sobre la llamada “inmigración irregular”. Se propone la noción de políticas de “control con rostro humano” (...) para dilucidar nuevas formas de control de las migraciones y las fronteras internacionales. A través del análisis del concepto de migración ordenada, ingresada al ámbito de gobierno de la migración con la emergencia de un nuevo régimen global de control, se pretende contribuir a la comprensión del origen y fundamento de algunos desplazamientos en las formas de pensar y ejercer el control de las migraciones internacionales en la Argentina actual.

We argue that the notion of individual is controversial not only for indistinguishable particles but also in the case of quantum distinguishable systems. We also argue that not only a picture in which “actual individuals” are taken into account is in contradiction with the quantum formalism, but also the case of “possible individuals” turns inconsistent within the quantum realm.

In this article we discuss the contextual character of quantum mechanics in the framework of modal interpretations. We investigate its historical origin and relate contemporary modal interpretations to those proposed by M. Born and W. Heisenberg. We present then a general characterization of what we consider to be a modal interpretation. Following previous papers in which we have introduced modalities in the Kochen-Specker theorem, we investigate the consequences of these theorems in relation to the modal interpretations of quantum mechanics.

La complejidad de la ciudad contemporánea apunta hacia el espacio público como lugar en el que percibir experiencias tanto estéticas como sociales. Por un lado, la estética urbana utiliza herramientas como el paisaje urbano y el arte público para estimular la percepción de lo bello en la ciudad. Por otra parte, el espacio urbano requiere de la actividad social para asentar su condición pública. Esta variable social, tanto en su vertiente perceptiva como participativa, presenta relaciones con el factor estético mediante (...) la interacción entre el medio físico y la sociedad que lo habita. La interpretación dual del espacio público como objeto estético y como fenómeno social contribuye a consolidar las nociones de lugar e identidad en la ciudad. (shrink)

sBuilding models as a practical aspect of ecological theory has as a principal purpose the determination of relations in formal language. In this paper, the authors provide a formalization of ecological models based on impure systems theory. Impure systems contain objects and subjects: subjects are human beings. We can distinguish a person as an observer that by definition is the subject himself and part of the system. In this case he acquires the category of object. Objects are significances, which are (...) the consequence of perceptual beliefs on the part of the subject about material or energetic objects with certain characteristics. The impure system approach is as follows: objects are perceptual significances of material or energetic objects. The set of these objects will form an impure set of the first order. The existing relations between these relative objects will be of two classes: transactions of matter and/or energy and inferential relations. Transactions can have alethic modality: necessity, possibility, impossibility and contingency. In this work we define measures which let us choose the more suitable variables to relate both the model with the ecosystem and with different models. In this way we define different comparison indexes. (shrink)

If the words in Spinoza’s Ethics are considered as symbols, then certain words in the definitions of the Ethics can be replaced with symbols from set theory and we can reexamine Spinoza’s first definitions within a logical–mathematical frame. The authors believe that, some aspects of Spinoza’s work can be explained and illustrated through mathematics. A semantic relation between the definitions of the philosopher and set theory is presented. It is explained each chosen symbol. The ontological argument is developed through modal (...) logic. And finally, we present some conclusions drawn from this work. (shrink)

In this paper, the authors try to clarify the relations between Meinong’s and Russell's thoughts on the ontological ideas of existence. The Meinongian theory on non-existent objects does not in itself violate the principle of non-contradiction, since the problem that this hypothesis offers to the theory of definite descriptions is not so much a logical problem as an ontological problem. To demonstrate this we will establish what we believe are the two main theses basic to the theory of descriptions: the (...) epistemological thesis and logical thesis. (shrink)

Suppes proposes an analysis of the structure and identity of empirical theories with his model-theoretical approach and undertakes effective reconstructions of theories in diverse disciplinary fields. Here the authors analyse the results of these examinations under the optics of questions concerning the assumed ontological commitments, and for how they satisfy economic and other criteria.

When faced with the threat of negative reputation spillover from an alliance partner accused of environmental misconduct, the focal firm must decide whether to adopt a supportive or non-supportive response. We argue that this decision denotes a commitment escalation dilemma, but that factors previously found to increase escalation tendencies lead to de-escalation in our crisis contagion context. Specifically, we derive four hypotheses from this reverse effect proposition, and test these using a policy-capturing survey targeting Norwegian CEOs. We found that firms (...) are more likely to select an adversary response when the alliance is of high strategic importance and has high termination costs. Conversely, firms are more likely to select an advocacy response when the alliance is of low strategic importance and has low termination costs and when the CEO was not involved in the formation of the alliance. Overall, our study answers a call for a more nuanced understanding of commitment escalation and the theory’s boundary conditions by introducing reputation spillover crisis as a contextual influencer of escalation behavior. It also extends the reputation literature and provides new evidence that reputation concerns can instigate ethical decision-making. (shrink)
