En física, el infinito aparece vinculado al problema de lo continuo de las representaciones matemáticas usadas por las diversas teorías y, por lo tanto, a la posibilidad de la infinita divisibilidad y de la infinita extensión de la geometría del espaciotiempo y de los conceptos y magnitudes físicas mensurables. El modelo estándar de las partículas considera que las partículas elementales son «infinitamente» pequeñas, donde surgen cálculos con resultados infinitos para determinadas cantidades físicas y, para eliminarlos, se utilizan métodos de renormalización, (...) usados también en la cosmología clásica y en el modelo estándar cosmológico del Big Bang con la finalidad de domesticar los infinitos. La investigación en gravedad cuántica considera que el espacio no sea infinitamente divisible y los modelos de multiversos suponen tiempos y espacios infinitos para el Universo. Siendo nuestras teorías siempre limitadas y perfectibles, parece que no podemos probar, en física, que el Universo sea físicamente infinito. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Spatializing Culture: The Ethnography of Space and Place by Setha LowCarlos J. L. BalsasSpatializing Culture: The Ethnography of Space and Placeby setha low London: Routledge, 2017Spatializing Culture: The Ethnography of Space and Place adds clarity to our understanding of the value of ethnographic scholarship in the study of socio-economic, cultural, and developmental transformations. The book is a thorough review of two established conceptual frames of analysis—the social production (...) of space and the social construction of space—coupled with an in-depth discussion of four newer ways to make sense of the world around us: embodied space, language and discourse, emotion and affect, and translocal space. As the world is transformed by a myriad of forces and events occurring simultaneously, its complexity intensifies insurmountably and we require clear and robust concepts, theories, methods, and tools to not only interpret it, but above all to attempt to change it in ways that are more beneficial to our collective co-existence while enabling the flourishing of those most at risk.Readers of Spatializing Culture will find plentiful theoretical constructs, lineages, diverse viewpoints, examples, and overall opportunities for reflecting on how the (built) environment, spaces, and places have been changing mostly due to our behavior. Inspired by Foucault’s take on genealogy, in chapter 2, Setha Low traces the history of space and place according to distinct interpretative schools of thought ranging from philosophical and mathematical, French social theory, geographical, architectural, environmental psychology, to anthropological, and even archeological. Five Venn diagrams are utilized to illustrate the main conceptual relationships between space and place. Most of the book’s in-depth case studies were researched by the author with only a small number investigated and written up by fellow scholars, which Low utilizes in the book with gratitude. The interrelated thematic and distinct geographical scope of the cases is one of the book’s hallmarks. The illustrative case studies come from such faraway places as Latin America (San José, Costa Rica), Asia (Taipei, Taiwan), North America (New York City; Washington, D.C.; Philadelphia, Pennsylvania; and San [End Page 151] Antonio, Texas), Southern Europe (Smederevska Palanka, Serbia), and the Middle East (Beirut, Lebanon; Cairo, Egypt; and Tel Aviv, Israel).Spatializing Culture was first mentioned to me years ago by a former colleague at the University at Albany, SUNY. His ongoing work in Latin America, coupled with his ethnographic training and prior work in a region of the world also extensively examined by Low in other scholarly works, was likely the reason for bringing it up in a conversation about the latest developments in the field and potential research opportunities. I acquired the book when I was teaching Global Urbanism and Culture and International Urban Planning. I was pleasantly surprised with the book’s thorough conceptual lineage, historic characterizations, attention to detail, comprehensive ethnographic investigations, and implications for transforming reality as well as institutional processes. Spatializing Culture is a welcome addition to urban planning textbooks, which tend to be relatively less critical, are often covered with normative constructs and statistics, and are more institutional in their characterization of problems and recommendations for further action.For the most part, the ethnographic method is qualitative, participa-tory, detailed, and quite comprehensive in characterizing key variables as the researcher found them on the ground. This differs slightly from urban planning’s preoccupation with public policy, policy analysis, rules and regulations, institutionalized procedures, the public good, and overall positivist and rationalist concerns with documenting reality and helping to lead transformative planning processes, whether in the realm of land use, transportation, housing, economic development, infrastructure, or the environment. Although International Urban Planning was to be taught in a rather orthodox manner with recourse to understanding planning cultures, best practices, lessons learned, and implications for similar situations, the Global Urbanism and Culture course was slightly more aligned with the discussions put forward by Low. These included attention to postmodern ideals, the use of creativity in community planning, distinctions between popular and highbrow culture, and the building of iconic structures in contexts of urban regeneration and mega-event planning. As such, my students were somewhat already exposed to issues of embodied spaces and to ideas of... (shrink)

Abstract:Implementing creative and sustainable urban planning initiates is rather challenging. This article argues that universities can become more relevant to underserved communities in their hinterlands by conducting town-gown citizen-science programs. Central to the article is a review of the most pertinent literature on public engagement, citizen-science, and other community based participatory methods utilized in the resolution of very complex health, social, environmental, and consumption problems. The research’s analytical mechanism is centered on the triad of Placeless, Place and Non-Place genius loci (...) of socio-spatial town-gown interventions. The curricular and pedagogical innovations identified entail the strengthening of citizen-science and design thinking in both high school and university education. (shrink)

When people engage in conversation, they tailor their utterances to their conversational partners, whether these partners are other humans or computational systems. This tailoring, or adaptation to the partner takes place in all facets of human language use, and is based on a mental model or a user model of the conversational partner. Such adaptation has been shown to improve listeners' comprehension, their satisfaction with an interactive system, the efficiency with which they execute conversational tasks, and the likelihood of achieving (...) higher level goals such as changing the listener's beliefs and attitudes. We focus on one aspect of adaptation, namely the tailoring of the content of dialogue system utterances for the higher level processes of persuasion, argumentation and advice-giving. Our hypothesis is that algorithms that adapt content for these processes, according to a user model, will improve the usability, efficiency, and effectiveness of dialogue systems. We describe a multimodal dialogue system and algorithms for adaptive content selection based on multi-attribute decision theory. We demonstrate experimentally the improved efficacy of system responses through the use of user models to both tailor the content of system utterances and to manipulate their conciseness. (shrink)

To this end, I propose to follow a somewhat unusual pattern, in that there will be no point-by-point consideration of issues raised by Taylor and Kullman. Instead, I intend to outline Merleau-Ponty's position on language, speech, and meaning as presented in the Phénoménologie de la Perception, and proceed from there to a discussion of the pre-objective.

The toy model used by Spekkens (Phys. Rev. A 75, 032110, 2007) to argue in favor of an epistemic view of quantum mechanics is extended by generalizing his definition of pure states (i.e. states of maximal knowledge) and by associating measurements with all pure states. The new toy model does not allow signaling but, in contrast to the Spekkens model, does violate Bell-CHSH inequalities. Negative probabilities are found to arise naturally within the model, and can be used to explain the (...) Bell-CHSH inequality violations. (shrink)

Some Presuppositions: • The following reflections, complex as they are, are governed by a reluctance to simplify Hindu teaching. I seek to avoid the view that the Hindu traditions had only one view of violence and nonviolence. • I use the term "Hindu" loosely and as a shorthand, without claiming that there is a single Hindu tradition, or a single creed shared by all Hindus, or a single attitude toward violence. But neither do I claim that there are simply many traditions without any common elements which justify the appellation "Hindu." • I am reluctant to idealize the Hindu traditions as if nonviolence must necessarily be taken as the epitome ofHindu thought. India's traditions are complex, and require complex treatment. • A serious artificiality of this paper is that I treat Hinduism without simultaneously lookinginto Buddhist andJain materials, though both were traditions with important and enduring commitments to nonviolence. Particularly with respect to the renunciant, marginal components of traditions, one ought not to make overly neat or decisive distinctions Violence and Nonviolence in Hindu Religious Traditions 1 1 1 between the Hindu, Buddhist, and Jain theories and practices related to violence and nonviolence. • I attempt to give preference to indigenous discussions ofissues related to violence and nonviolence; the context and mode of thinking are important, notjust the conclusions drawn. I therefore avoid simply mining Hindu texts for an answer to a contemporary question, "What is the Hindu attitude toward violence and nonviolence?" • In most ofwhat follows we must distinguish contexts where "violence" indicates "physical action which causes pain to some living being," from contexts where "violence" indicates "an intention, rooted in anger or malice, to hurt someone." I use the word "violence" for both in order to highlight the complex issues of distinction involved. In considering the Sanskrit formulations, one likewise has to distinguish himsa as "causing pain" from himsa as "intending to harm." • It is often difficult to date ancient texts, and even when one narrows down a date—within 200-300 years—its significance still depends on other, often equally broadly stated dates. Nevertheless, I do offer dates throughout, as summarized here: •ancient Vedic sacrificial practices, from before 1200 BCE •Vedic ritual analyses and reformulations of sacrifices as ritualized acts, in the Brahmanas, from after 1000 BCE •the Upanishadic exploration of the deeper meanings of ritual and interiorized alternatives to ritual, from after 900 BCE •the Buddha, c. 500 BCE •key texts in the theorization of royal power, The Laws of Manu (beginning of Common Era) and Arthashastra (c. 150 CE) •the Tamil wisdom text Tirukkural (100 CE) •Goddess texts as evidenced in Sanskrit formulations, from after 500 CE...

Charles S. Peirce has a great deal to contribute both to understanding and to solving many of the philosophical problems which puzzle contemporary thinkers. In fact it is probably true that in some ways philosophers of our time are in a better position to understand Peirce's thought than those of his own day. In this paper I would like to consider two puzzling notions: 1) the substantiality of things, and 2) the foundations of human knowledge.

Las corrientes filosóficas de inspiración cartesiana tarde o temprano tienen que afrontar el solipsismo como un resultado al menos plausible de su desarrollo. La Fenomenología no podía evitar la misma suerte. Después de un rápido panorama en lo tocante a la fenomenología husserliana y el solipsismo, pasamos a exponer críticamente el texto de las Meditaciones cartesianas de Husserl, específicamente la quinta. Intentaremos señalar la insuficiencia de la exposición husserliana a la hora de superar, desde sus propias bases, la amenaza del (...) solipsismo. (shrink)

In this article, we focus on the concept of leadership ethics and make observations about transformational, transactional and servant leadership. We consider differences in how each definition of leadership outlines what the leader is supposed to achieve, and how the leader treats people in the organization while striving to achieve the organization's goals. We also consider which leadership styles are likely to be more popular in organizations that strive to maximize short run profits. Our paper does not tout or degrade (...) any of these leadership theories. Instead, it points out which theories allow reason to play more than a minimal role in ethical decision-making, as well as those that are most consistent with a firm's desire to achieve efficiency in the short run. We explain our view that the way leadership is practiced in large, bureaucratic organizations suggests that ethics is often absent from the leader's decision-making process. Consequently, we suggest that before we engage in a meaningful dialogue about what kind of leaders we might really want in business, we must consider how much short-run profit we are willing to forego in exchange for more ethical corporate cultures.

Metaphysicians go on busily doing metaphysical thinking all over the world, and apparently with a modicum of self-assurance that they are not talking nonsense or pursuing an illusory will-of-the-wisp. Yet other philosophers of empirical, analytical, phenomenological, or other turns of mind seem to have more and more difficulty in understanding just how metaphysicians give meaning and positive content to the vast abstract concepts by which they seek to describe and explain the entire spectrum of reality extending far beyond present or (...) perhaps even possible human experience. Since there is no way of gaining direct insight into dimensions of reality beyond human experience, and since in order to be applied to the whole range of reality these concepts must abstract from purely human experience, it is hard for them to see—and it is a serious problem in itself—how these all-embracing terms can be anything more than empty, formal, verbal symbols or conceptual constructions, with no positive existential content describing reality itself across its whole spectrum. Even the metaphysician himself, though when left alone he may have a sure sense of how to do metaphysical thinking fruitfully, when questioned to explain and justify what he is doing, and is convinced is worth doing, can feel embarrassed and struck dumb as to how to articulate and justify the principles behind the procedures he is following.
