“‘Relentless Geography’: Los Angeles’ Imagined Cartographies in Karen Tei Yamashita’s Tropic of Orange,”

What would a map of Los Angeles drawn from the ground up look like? In his groundbreaking work The Production of Space (1974), Henri Lefebvre argues that the conceived space of urban planners is fundamentally distinct from lived space, which cannot be mapped out. In her impressive city-wide narrative, Karen Tei Yamashita’s Tropic of Orange (1997) demonstrates the effects of imposing conceived space upon the lived space of inner city Los Angeles residents, and what happens when the counter-model of space being lived by a city’s inhabitants rebels. Yamashita’s text mirrors this disjuncture between represented and lived space through the use of narrative surrealism. Space is magically reconfigured in the city, shrinking the uninhabited Downtown and expanding over-populated yet underrepresented neighborhoods, literally shifting geographically until its mapping matches the social space of those on the ground rather than those who map it from above. Literary criticism on the novel to date has largely interpreted Tropic of Orange as a commentary on the effects of globalization; not enough attention has been paid to the novel’s surreal expansion of Los Angeles’ inner city. Using Lefebvre’s “science of space,” anchored by Los Angeles’ city planning schemas, I argue that Yamashita offers a different map, one perceived by the subsets of LA’s population that fall through the cracks of the city’s grid. Tropic of Orange’s unorthodox formal structure, when combined with its narrative surrealism, creates a differential space in the text, transforming the novel into the Los Angeles imagined by its anonymous users

Historic cartography of L'Aquila city as a support to the study of earthquake damaged buildings

The city-center of L'Aquila suffered big damages from the main seismic event (6th April 2009, 3:32 a.m., local time; Ml=5.8, Mw= 6.2) of the seismic sequence that included hundreds of aftershocks (more than 30 of them 3.5<5.0) (INGV, 2009). Causes and modality of the collapse of some buildings are still under investigation. A 1:2000 map representing the center of L'Aquila city at the beginning of twentieth century was recently found and the comparison of this map with contemporary ones can help the study of the causes of the different response to seismic stress to different aged buildings. This study represents the first step to build a database of historic buildings in L'Aquila to test a potential correlation between the anti-earthquake regulations adopted over the years and the resulting damages. A comparison with post earthquakes damage map and the map of seismic zoning was performer to find all the possible combination of other parameters that together with building age can help to evaluate building vulnerability

Some Inquiries to Spontaneous Opinions: A case with Twitter in Indonesia \ud

The paper discusses opportunities to utilize the series of micro-blogs as provided by the Twitter in observation of opinion dynamics. The spontaneity of tweets is more, as the service is attached more to the mobile communications. The extraction of information in the series of tweets is demonstrated as in conceptual map and mention map. From the latter, the social network stylized properties, i.e.: power law distribution is shown. The exemplification of the methodology is on the 82nd commemoration of Indonesian Youth Pledge and the participatory movement of Indonesian capitol city, Jakarta

Geomorphological classification of urban landscapes. The case study of Rome (Italy)

The results of a long-lasting geomorphological survey carried out in Rome are summarized. A method aimed at integrating survey data, historical maps, aerial photographs and archaeological and geomorphological literature produced a geomorphological map of the present-day historical centre. The geomorphology of Rome is related to the paleogeographical conditions prior to the founding of the City; they allow us to recognize the stages of landscape evolution of the ancient Caput Mundi (Capital of the World). The study area has been affected by continuous man-made changes to the drainage network and to the topographic surface over the last 3000 years. It has forced the authors to develop innovative solutions to undertake effective analysis of the urban environment and the legend of the geomorphological map in this peculiar context. The resulting map is useful for urban planning and archaeological research

Multidimensional Urban Segregation - Toward A Neural Network Measure

We introduce a multidimensional, neural-network approach to reveal and measure urban segregation phenomena, based on the Self-Organizing Map algorithm (SOM). The multidimensionality of SOM allows one to apprehend a large number of variables simultaneously, defined on census or other types of statistical blocks, and to perform clustering along them. Levels of segregation are then measured through correlations between distances on the neural network and distances on the actual geographical map. Further, the stochasticity of SOM enables one to quantify levels of heterogeneity across census blocks. We illustrate this new method on data available for the city of Paris.Comment: NCAA S.I.

Networks and Cities: An Information Perspective

Traffic is constrained by the information involved in locating the receiver and the physical distance between sender and receiver. We here focus on the former, and investigate traffic in the perspective of information handling. We re-plot the road map of cities in terms of the information needed to locate specific addresses and create information city networks with roads mapped to nodes and intersections to links between nodes. These networks have the broad degree distribution found in many other complex networks. The mapping to an information city network makes it possible to quantify the information associated with locating specific addresses.Comment: 4 pages, 4 figure

The experiment of Community involvement in a project planning within the historical context of Rome city

The PhD student proposes a method of community involvement in the planning and in the regeneration of historical centers, in support of the city’s accessibility and people’s well-being. The outcomes of the research are the analysis and the studies conducted over three years with people with sensory, physical and cognitive impairments on the sustainable mobility of historical spaces of Rome, thanks to an agreement between the Phd Student Start up Research Project financed by Sapienza, Università di Roma and the Municipality of Rome. Citizens are involved in the analysis process: they communicate their opinions, impressions, perceptions and needs related to the city experience through a dedicated help-desk, in return, they receive an advice service and a design project for their apartment that suits their necessities. Thanks also to several tours and surveys conducted with people with special needs, the phd student studies the human senses, the perception of the space, the physical barriers, natural and urban elements, with the aim to elaborate an accessibility-map of the City Center Cultural Heritage and Archaeological Sites. Citizens can contribute by sharing information about the status of the public spaces, or by giving advice on adaptive-ergonomic urban furnishings. The research aims to elaborate an application for mobile systems that identifies an interactive cartography of the city available for all the citizens, especially people with reduced mobility. The map, developed on multiple layers, also contains the layer made up of people’s emotions and their perceptions
