Image-Based Spatialization

An approach to spatialization is described in which the pixels of an image determine both spatial and other attributes of individual elements in a multi-channel musical texture. The application of this technique in the author’s composition Spaced Images with Noise and Lines is discussed in detail. The relationship of this technique to existing image-to-sound mappings is discussed. The particular advantage of modifying spatial properties with image filters is considered.

From "Spaces of Fear" to "Fearscapes": Mapping for Reframing Theories About the Spatialization of Fear in Urban Space

The article engages with theory about the processes of spatialization of fear in contemporary Western urban space (fortification, privatization, exclusion/seclusion, fragmentation, polarization) and their relation to fear of crime and violence. A threefold taxonomy is outlined (Enclosure, Post-Public Space, Barrier), and “spaces of fear” in the city of Palermo are mapped with the aim of exploring the cumulative large-scale effects of the spatialization of fear on a concrete urban territory. Building on empirical evidence, the author suggests that mainstream theories be reframed as part of a less hegemonic and more discursive approach and that theories mainly based on the analyses of global cities be deprovincialized. The author argues for the deconstruction of the concept of “spaces of fear” in favor of the more discursive concept of “fearscapes” to describe the growing landscapes of fear in contemporary Western cities.

Fuzzy Logic and Geostatistical Techniques for Spatialization of Soil Texture in Region with Rough Terrains

From the geotechnical standpoint, it is interesting to analyse the soil texture in regions with rough terrain due to its relation with the infiltration and runoff processes and, consequently, the effect on erosion processes. The purpose of this paper is to present a methodology that provides the soil texture spatialization by using Fuzzy logic and Geostatistic. The results were correlated with maps drawn specifically for the study area. The knowledge of the spatialization of soil properties, such as the texture, can be an important tool for land use planning in order to reduce the potential soil losses during rain seasons.

Typologies and spatialization of agricultural production systems in Rondônia, Brazil: linking land use, socioeconomics and territorial configuration.

The current Amazon landscape consists of heterogeneous mosaics formed by interactions between the original forest and productive activities. Recognizing and quantifying the characteristics of these landscapes is essential for understanding agricultural production chains, assessing the impact of policies, and in planning future actions. Our main objective was to construct the regionalization of agricultural production for Rondônia State (Brazilian Amazon) at the municipal level. We adopted a decision tree approach, using land use maps derived from remote sensing data (PRODES and TerraClass) combined with socioeconomic data. The decision trees allowed us to allocate municipalities to one of five agricultural production systems: (i) coexistence of livestock production and intensive agriculture; (ii) semi-intensive beef and milk production; (iii) semi-intensive beef production; (iv) intensive beef and milk production, and; (v) intensive beef production. These production systems are, respectively, linked to mechanized agriculture (i), traditional cattle farming with low management, with (ii) or without (iii) a significant presence of dairy farming, and to more intensive livestock farming with (iv) or without (v) a significant presence of dairy farming. The municipalities and associated production systems were then characterized using a wide variety of quantitative metrics grouped into four dimensions: (i) agricultural production; (ii) economics; (iii) territorial configuration, and; (iv) social characteristics. We found that production systems linked to mechanized agriculture predominate in the south of the state, while intensive farming is mainly found in the center of the state. Semi-intensive livestock farming is mainly located close to the southwest frontier and in the north of the state, where human occupation of the territory is not fully consolidated. This distributional pattern reflects the origins of the agricultural production system of Rondônia. Moreover, the characterization of the production systems provides insights into the pattern of occupation of the Amazon and the socioeconomic consequences of continuing agricultural expansion.

Creating a scene: Balinese punk's beginnings

The promotion of alternative music by deregulated television and recording industries, together with the increasingly felt presence of the metropolis, converged on Balinese cultural and physical landscapes in the 1990s. Mirroring developments in broader society, a regionalist discourse, which polarized notions of ‘centre’ and ‘periphery’, emerged among Balinese youth in the context of the local band scene. For certain musicians, musical authenticity was firmly rooted in a cultural and geographical locale, and was articulated by their abhorrence for socializing at shopping malls. In contrast, these Balinese alternative (including punk) musicians sought authenticity in a metropolitan elsewhere. This article is a case study of the indigenization of a ‘global’ code in a non-western periphery. It contests arguments for the ‘post-imperial’ nature of globalization, and demonstrates the continued salience of centre–periphery dialectics in local discourses. At the same time, the study attests to the progressive role a metropolitan superculture can play in cultural renewal in the periphery.

The subject and architecture

Invited Presentation on my book Architecture for a Free Subjectivity. In March of 1982, Skyline, the Institute for Architecture and Urban Studies serial, published the landmark interview between Paul Rabinow, an American anthropologist, and Michel Foucault, which would only appear two years later under the title “Space, Knowledge, and Power,” in Rabinow’s edited book The Foucault Reader. Foucault said that in the spatialization of knowledge and power beginning in the 18th century, architecture is not a signifier or metaphor for power, it is rather the “technique for practising social organization.” The role of the IAUS in the architectural dissemination of Foucault’s ideas on the subject and space in the North American academy – such as the concept “heterotopia,” and Foucault’s writing on surveillance and Jeremy Bentham’s Panopticon, subsequently analysed by Georges Teyssot, who was teaching at the Venice School – is well known. Teyssot’s work is part of the historical canalization of Foucauldianism, and French subjectivity more broadly, along its dizzying path, via Italy, to American architecture schools, where it solidified in the 1980s paradigm that would come to be known as American architecture theory. Foucault was already writing on incarceration and prisons, from the 1970s. (In the 1975 lectures he said “architecture was responsible for the invention of madness.”) But this work was not properly incorporated into architectural discussion until the early ’80s. What is not immediately apparent, what this history suggests to me is that subjectivity was not a marginal topic within “theory”, but was perhaps a platform and entry point for architecture theory. One of the ideas that I’m working on is that “theory” can be viewed, historically, as the making of architectural subjectivity, something that can be traced back to the Frankfurt School critique which begins with the modern subject...

Paisagem e Escassez : espaço e experimentação

Analysis and Synthesis of Reverberation for Parametric Stereo Audio

We propose a parametric stereo coding analysis and synthesis directly in the MDCT domain using an analysis by synthesis parameter estimation. The stereo signal is represented by an equalized sum signal and spatialization parameters. Equalized sum signal and the spatialization parameters are obtained by sub-band analysis in the MDCT domain. The de-correlated signal required for the stereo synthesis is also generated in the MDCT domain. Subjective evaluation test using MUSHRA shows that the synthesized stereo signal is perceptually satisfactory and comparable to the state of the art parametric coders.

Spatial hearing and sound perception in musical composition

This thesis explores the possibilities of spatial hearing in relation to sound perception, and presents three acousmatic compositions based on a musical aesthetic that emphasizes this relation in musical discourse. The first important characteristic of these compositions is the exclusive use of sine waves and other time invariant sound signals. Even though these types of sound signals present no variations in time, it is possible to perceive pitch, loudness, and tone color variations as soon as they move in space due to acoustic processes involved in spatial hearing. To emphasize the perception of such variations, this thesis proposes to divide a tone in multiple sound units and spread them in space using several loudspeakers arranged around the listener. In addition to the perception of sound attribute variations, it is also possible to create rhythm and texture variations that depend on how sound units are arranged in space. This strategy permits to overcome the so called "sound surrogacy" implicit in acousmatic music, as it is possible to establish cause-effect relations between sound movement and the perception of sound attribute, rhythm, and texture variations. Another important consequence of using sound fragmentation together with sound spatialization is the possibility to produce diffuse sound fields independently from the levels of reverberation of the room, and to create sound spaces with a certain spatial depth without using any kind of artificial sound delay or reverberation.

Fear and Urban Planning in Ordinary Cities: From Theory to Practice

The paper complements Abu-Orf's theory about violent settings by setting out a theory of fear in urban planning in ordinary urban contexts around three arguments: spatialization of fear; (modernist) spatialities and the encounter and political economies of urban fear. The three theoretical arguments are used to re-frame the planning history of Chelas, an affordable housing district in Lisbon, Portugal, and debate the way fear shapes, and is shaped in turn by, planning practice. Confirming that (growing) fear in ordinary urban contexts is not just an effect of the contemporary organization of cities, the paper argues for a theorization of fear that combines global (hegemonic) and a local (discursive/contingent) perspectives in the theorization of urban fear, and advocates for the need to put fear, and its capacity to create a crisis in urban policy, at the heart of planners' agendas.

Unnoticed apocalypse: the science fiction politics of urban crisis

The slogan ‘capitalism is crisis’ is one that has recently circulated swiftly around the global Occupy movement. From Schumpeter to Marx himself, the notion that the economic cycles instituted by capitalism require periodic crises as a condition of renewed capital accumulation is a commonplace. However, in a number of recent texts, this conception of crisis as constituting the very form of urban capitalist development itself has taken on a more explicitly apocalyptic tone, exemplified by the Invisible Committee's influential 2007 book The Coming Insurrection, and its account of what it calls simply ‘the metropolis’. ‘It is useless to wait’, write the text's anonymous authors, ‘for a breakthrough, for the revolution, the nuclear apocalypse or a social movement.… The catastrophe is not coming, it is here.’ In considering such an apocalyptic tone, this paper thus situates and interrogates the text in terms both of its vision of the metropolis as a terrain of total urbanization and its effective spatialization of the present as itself a kind of ‘unnoticed’ apocalypse: the catastrophe which is already here. It does so by approaching this not only apropos its place within contemporary debates surrounding leftist politics and crisis theory but also via its imaginative intersection with certain post-1960s science fiction apocalyptic motifs. What, the paper asks, does it mean to think apocalypse as the ongoing condition of the urban present itself, as well as the opening up of political and cultural opportunity for some speculative exit from its supposedly endless terrain?
