The global pesticide complex has transformed over the past two decades, but social science research has not kept pace. The rise of an enormous generics sector, shifts in geographies of pesticide production, and dynamics of agrarian change have led to more pesticide use, expanding to farm systems that hitherto used few such inputs. Declining effectiveness due to pesticide resistance and anemic institutional support for non-chemical alternatives also have driven intensification in conventional systems. As an inter-disciplinary network of pesticide scholars, we (...) seek to renew the social science research agenda on pesticides to better understand this suite of contemporary changes. To identify research priorities, challenges, and opportunities, we develop the pesticide complex as a heuristic device to highlight the reciprocal and iterative interactions among agricultural practice, the agrochemical industry, civil society-shaped regulatory actions, and contested knowledge of toxicity. Ultimately, collaborations among social scientists and across the social and biophysical sciences can illuminate recent transformations and their uneven socioecological effects. A reinvigorated critical scholarship that embraces the multifaceted nature of pesticides can identify the social and ecological constraints that drive pesticide use and support alternatives to chemically driven industrial agriculture.

The Aymara of the Andes use absolute (cardinal) frames of reference for describing the relative position of ordinary objects. However, rather than encoding them in available absolute lexemes, they do it in lexemes that are intrinsic to the body: nayra (“front”) and qhipa (“back”), denoting east and west, respectively. Why? We use different but complementary ethnographic methods to investigate the nature of this encoding: (a) linguistic expressions and speech–gesture co-production, (b) linguistic patterns in the distinct regional Spanish-based variety Castellano Andino (...) (CA), (c) metaphorical extensions of CA’s spatial patterns to temporal ones, and (d) layouts of traditional houses. Findings indicate that, following fundamental principles of Aymara cosmology, people, objects, and land—as a whole—are conceived as having an implicit canonical orientation facing east, a primary landmark determined by the sunrise. The above bodily based lexicalizations are thus linguistic manifestations of a broader macro-cultural worldview and its psycho-cognitive reality. (shrink)

Este artigo tem como objetivo discutir a relação entre a construção de uma postura individualista como estratégia de cuidado de si dentro do contexto atual em que vivemos. Para tanto é realizado uma reflexão a partir da idéia de “sociedade de consumidores” trazida por Zygmunt Bauman, buscando construir uma relação desta com diferentes campos de atuação do sujeito humano. O que encontramos é uma postura que busca defender o indivíduo de possíveis riscos, sendo o outro, seu principal alvo de controle. (...) Dessa forma, constrói-se um individualismo que não pode ser confundido com a postura ascética do cuidado de si grego que possuía em seu conceito a dimensão trágica como suporte a política da existência. Ao final, concebe-se a resistência às políticas de controle de desejos como saída aos dispositivos presentes na sociedade de consumo. (shrink)

El conocido pensador refuta la antropología moderna y brinda argumentos aún más profundos.

This survey chapter discusses four issues in architectural aesthetics: architectural design, architectural style, the justification of “optical correction”, and the metaphysics of reconstruction.

There have been two major lines of research aimed at capturing resource-bounded players in game theory. The first, initiated by Rubinstein (), charges an agent for doing costly computation; the second, initiated by Neyman (), does not charge for computation, but limits the computation that agents can do, typically by modeling agents as finite automata. We review recent work on applying both approaches in the context of decision theory. For the first approach, we take the objects of choice in a (...) decision problem to be Turing machines, and charge players for the “complexity” of the Turing machine chosen (e.g., its running time). This approach can be used to explain well-known phenomena like first-impression-matters biases (i.e., people tend to put more weight on evidence they hear early on) and belief polarization (two people with different prior beliefs, hearing the same evidence, can end up with diametrically opposed conclusions) as the outcomes of quite rational decisions. For the second approach, we model people as finite automata, and provide a simple algorithm that, on a problem that captures a number of settings of interest, provably performs optimally as the number of states in the automaton increases.

What is a ‘number,’ as studied within numerical cognition? The term is highly polysemous, and can refer to numerals, numerosity, and a diverse collection of mathematical objects, from natural numbers to infinitesimals. However, numerical cognition has focused primarily on prototypical counting numbers – numbers used regularly to count small collections of objects. Even these simple numbers are far more complex than apparent pre-conditions for numerical abilities like subitizing and approximate discrimination of large numerosity, which we share with other animals. We (...) argue that the leap to number concepts proper relies, in part, on two embodied, domain-general cognitive mechanisms: conceptual metaphor and fictive motion. These mechanisms were first investigated within cognitive linguistics, a subdiscipline of cognitive science, but are now thought to subserve cognition more generally. We review the proposal that these mechanisms structure numerical cognition – including PCNs, but also the positive integers and arithmetic – and survey the supporting empirical evidence. (shrink)

Oases have served as sacred landscapes and sources of ritual plants in arid regions of the Old and New Worlds. We evaluate the Jesuit mission oases of the Baja California peninsula for their role in agrobiodiversity persistence, and extend theories of sacred landscapes and biodiversity conservation to agricultural species and practices. Jesuit missionaries on the peninsula introduced a suite of crops species and agricultural and water management systems that persist in the oases and have become an integral part of the (...) cultural and religious identity of the peninsula. The sacred landscapes of the oases are defined by elements of the Jesuit mission systems, such as water capture systems and irrigation canals, stone field borders and terraces, field gardens or huertas, groves of olive trees and date palms, and multi-tiered agroecosystems. Sacred practices—including pilgrimages, religious rites, and Catholic-based community celebrations—depend on the integrated “landscapes” of the oases and on the ritual use of wild and cultivated oasis plant species. We propose that some, though not all, of the peninsula oases may be considered as sacred landscapes responsible for maintaining heritage crop species, biodiversity, and traditional farming and foodways practices.

What distinguishes the Socrates of the early from the Socrates of the middle dialogues? According to a well-known opinion, the “dividing line” lies in the difference between the Socratic and the Platonic theory of action. Whereas for the Platonic Socrates of the early dialogues, all desires are good-dependent, for the Platonic Socrates of the middle dialogues, there are good-independent desires. The paper argues first that this “dividing line” is blurred in the "Symposium", and second that we have in the "Symposium" (...) a more distinctive dividing line, namely the introduction of the separate existence of the idea of beauty. This introduction by Diotima/Plato of separate ideas and the lack of understanding of separate ideas – here the idea of beauty – by Socrates may have been the limit not only of the Socrates of the early Platonic dialogues, but of the historical Socrates as well.

Computer vision research involving street and road detection methods usually focuses on driving assistance and autonomous vehicle systems. In this context, street segmentation occurs in real-time, based on images centered on the street. This work, on the other hand, uses street segmentation for urban planning research to classify pavement types of a city or region, which is particularly important for developing countries. For this application, it is needed a dataset with images from various locations for each street. These images are (...) not necessarily centered on the street and include challenges that are not common in street segmentation datasets, such as mixed pavement types and the presence of faults and holes on the street. We implemented a multi-class version of a state-of-the-art segmentation algorithm and adapted it to perform street pavement classification, handling navigation along streets and angle variation to increase the accuracy of the classification. A data augmentation approach is also proposed to use preliminary results from the test instances as new ground truth and increase the amount of training data. A dataset with more than 300,000 images from 773 streets from a Brazilian city was built. Our approach achieved a precision of 0.93, showing the feasibility of the proposed application. (shrink)

This is an interdisciplinary work product of reflection on the challenges today presented by a biological vision of the world regarding questions, concepts and notions of cosmology. Based on and in dialogue with the current state of biological research, this work deals with certain cosmological problems such as that between the living and the inert, the traditional division between the soul or the vital vegetative principle, sensitive or intellective; the problem of individuation and the concept of species, among others; the (...) solution found within classical philosophy in this paper takes into account the latest discoveries findings of modern biology.

O artigo pretende examinar um aspecto ainda pouco explorado no parágrafo 36 de Além do bem e do mal (BM), a saber: a função e o alcance do princípio da economia para a apresentação da hipótese da vontade de poder. A pertinência do princípio se estabelece, ao menos, a partir de Ockham e Newton, que prescrevem a simplicidade como critério para a decisão entre teorias ou explicações concorrentes. O foco aqui, no entanto, será a adesão efetivada por Richard Avenarius e (...) Ernst Mach, que conduzem o princípio da economia ao centro metodológico de seus empreendimentos filosóficos e são relevantes fontes para o uso que Nietzsche faz do princípio em BM §36. Avalia-se, por fim, que Nietzsche promove a redução econômica e estratégica ao confronto de forças (ou vontades) como alternativa à redução empiriocrítica, restrita a uma compreensão físico-mecânica do mundo, de Avenarius e Mach. Pondera-se também, como contraexemplo do princípio da economia, o paralelismo psicofísico de Wundt. Em suas considerações finais, o artigo indica, como perspectiva para futuros trabalhos, algumas vantagens da abordagem da vontade de poder a partir do princípio em questão, em especial, uma renovada direção para o exame do problema da circularidade e autorreferência.

Nuevo México y Centroamérica se unen por una historia pre-hispánica y colonial común. Mientras las lenguas yuto-nicaraos se expanden de Utah, EE.UU., a Nicaragua, los peregrinos del Cristo de Esquipulas viajan desde El Trifinio (Triángulo Norte de Centroamérica) a Chimayó (NM). Se exploran ambos bordes de un antiguo Virreinato al revelar su enlace por un Camino Real (entre realeza y realidad), cuyas señales olvidadas solo las reconoce una deposición testimonial subjetiva. En primer lugar, una crónica personal desglosa la extrañeza hispana (...) ante su propio legado en EE.UU., el cual los emparentaría con el Sur. En seguida, el ensayo comenta los enlaces culturales y lingüísticos ancestrales que mantienen tradiciones comunes —irreconocidas por nacionalismo cívico— entre el suroeste de los EE.UU. y el triángulo norte de Centroamérica.

Nos acercamos a la figura de Gabriel Riesco Fernández del Campo por ser una de las más prolíficas de la planificación urbana de España y El Salvador del siglo XX, como autor de más de 180 planes. Tras el estudio de su biografía y de algunas de sus obras podemos situarlo en la más alta Administración pública de ambos países, donde su trabajo fue determinante para su ordenación territorial, en los años 50 y tras el terremoto de 1986 en Centroamérica, (...) y en España durante el desarrollismo y la constitución de las Comunidades Autónomas. Asimismo fue asesor de Naciones Unidas para la ordenación territorial en El Salvador. Su obra arquitectónica es aún más desconocida. (shrink)

En algunos sectores crece la convicción de que la universidad es innecesaria y que puede ser remplazada por una serie de dispositivos perfectamente alineados a los intereses de la empresa. Se multiplican los expertos que anuncian la muerte de la universidad. Conviene reflexionar sobre los rasgos que tendría ese mundo sin universidades y destacar la necesidad de un espacio libre de condicionamientos políticos y económicos.

Se ofrece una caracterización de los abordajes sofístico y filosófico de la política y, posteriormente, se describen ciertas perspectivas contemporáneas de conceptualización y acción política, con el propósito de señalar las coincidencias y paralelismos entre estas y los modelos clásicos sugeridos. Este ejercicio propende por analizar las consecuencias de la actualización que algunos autores contemporáneos han hecho, por un lado, del criterio relativista apropiado por la figura del sofista y, por otro, del juicio universalista adoptado por la contrafigura del filósofo, (...) para evaluar la procedencia de una hipótesis según la cual el relativismo gestado en la tradición sofista tiene un lugar protagónico y dominante en la cultura política de nuestra época.

Nuestro principal objetivo en este trabajo es el de analizar si es posible construir sistemas lógicos temporales-epistémicos lo suficientemente satisfactorios. Sin embargo, las principales dificultades para lograr este propósito provienen del hecho de tener que combinar una perspectiva temporal absoluta con una perspectiva epistémica relativa a cada agente; es decir, por un lado, los instantes de tiempo vienen determinados desde el punto de vista de un observador situado fuera del mundo, y, por otro lado, las alternativas epistémicas de cada agente (...) son relativas a dicho agente. Pensamos que algunas de estas dificultades podrían ser superadas con la ayuda de las lógicas híbridas, puesto que este tipo de lógicas simplifica la combinación de sistemas temporales y epistémicos, y así podemos evitar tener que construir modelos excesivamente complicados. Our main goal in this paper is to analyse if it is possible to build some suitable Temporal-Epistemic Systems. However, the main difficulties in order to aim this goal come from the fact of having to combine an absolute temporal perspective with a relative epistemic perspective; that is, on one hand, temporal points are determined from the point of view of an observer placed outside the world, and, on the other hand, the epistemic alternatives of each agent are relative to that agent. We think that some of these difficulties could be solved with the help of hybrid logics, because this kind of logics simplifies the combination of temporal and epistemic systems, and so we can avoid building highly complicated models.

A critically acute summary of the main theories about the 'State', from Greek antiquity to the present. The authors highlight the importance of archaeology to our knowledge of how the first States were formed and how they functioned. They also ask what conditions of social production led to the State arising as the self-interested regulator of social relationships.

ResumenLos abundantes análisis filosóficos sobre la física cuántica no se han visto en general acompa- ñados por una consideración equiparable hacia su prolongación natural en la teoría cuántica de campos. Esta teoría se ha revelado en su versión electromagnética como una de las herramientas predictivas más precisas de la ciencia física. No obstante, sus cimientos conceptuales siguen siendo altamente controvertidos y cabe dudar si una ampliación de su formalismo conducirá a la tan deseada unificación de las fuerzas fundamentales, y por (...) ende, a una comprensión global de las propiedades básicas de la naturaleza.Palabras claveFilosofía de la física, teoría cuántica de campos, unificación de fuerzas, predicciónAbstractThe abundant philosophical analyses on quantum physics have not been generally followed by an equivalent consideration toward their natural continuation in the quantum field theory. This theory is regarded in its electromagnetic version as one of the best predictive tools in physical science. Nevertheless, its conceptual foundations are still surrounded by controversy and it is doubtful if an extension of its formalism will lead us to the unification of the four basic forces, and therefore to a global understanding of the basic properties of nature.KeywordsPhilosophy of physics, quantum field theory, unification of forces, prediction.

According to Locke’s Principle, material objects are identical if and only if they are of the same kind and once occupy the same place at the same time. There is disagreement about whether this principle is true, but what is seldom disputed is that, even if true, the principle fails to constitute an applicable criterion of identity. In this paper, I take issue with two arguments that have been offered in support of this claim by arguing (i) that we can (...) have knowledge of past whereabouts, and so verify the right hand side of Locke’s Principle, without having to assess concrete identity claims first; (ii) that even under conditions of incomplete knowledge of past whereabouts we can use Locke’s Principle to decide concrete identity problems.
