An Introduction to Critical Cartography

Abstract: This paper provides a brief introduction to critical cartography. We define critical cartography as a one-two punch of new mapping practices and theoretical critique. Critical cartography challenges academic cartography by linking geographic knowledge with power, and thus is political. Although contemporary critical cartography rose to prominence in the 1990s, we argue that it can only be understood in the historical context of the development of the cartographic discipline more generally. We sketch some of the history of this development, and show that critiques have continually accompanied the discipline. In the post-war period cartography underwent a significant solidification as a science, while at the same time other mapping practices (particularly artistic experimentation with spatial representation) were occurring. Coupled with the resurgence of theoretical critiques during the 1990s, these developments serve to question the relevance of the discipline of cartography at a time when mapping is increasingly prevalent and vital.

A Private and Efficient Mechanism for Data Uploading in Smart Cyber-Physical Systems

Abstract: To provide fine-grained access to different dimensions of the physical world, the data uploading in smart cyber-physical systems suffers novel challenges on both energy conservation and privacy preservation. It is always critical for participants to consume as little energy as possible for data uploading. However, simply pursuing energy efficiency may lead to extreme disclosure of private information, especially when the uploaded contents from participants are more informative than ever. In this article, we propose a novel mechanism for data uploading in smart cyber-physical systems, which considers both energy conservation and privacy preservation. The mechanism preserves privacy by concealing abnormal behaviors of participants, while still achieves an energy-efficient scheme for data uploading by introducing an acceptable number of extra contents. To derive an optimal uploading scheme is proved to be NP-hard. Accordingly, we propose a heuristic algorithm and analyze its effectiveness. The evaluation results towards a real-world dataset demonstrate that the performance of the proposed algorithm is comparable with the optimal results.

Maps as social constructions: power, communication and visualization

Abstract: Two developments in cartography mark an epistemic break with the assumption that maps are unproblematic communication devices. These are 1) investigations of maps as practices of power-knowledge; and 2) 'geographic visualization' (GVis) which uses the map's power to explore, analyze and visualize spatial datasets to understand patterns better. These developments are key components of a 'maps as social constructions' approach, emphasizing the genealogy of power in mapping practices, and enabling multiple, contingent and exploratory perspectives of data. Furthermore, this approach is an opportunity for cartography to renew its relationship with a critical human geography.

The Role Of Organizational Controls In Managing Knowledge

Abstract: We present a model demonstrating the role of organizational controls in managing organizational knowledge characterized by different combinations of knowledge attributes. Specifically, we show how particular controls (outcome, process, and clan) differ in their ability to acquire, transfer, interpret, and, finally, use knowledge. We argue that the use of different controls therefore creates distinguishably different knowledge management processes within the firm.

PHENIX detector overview

Abstract: The PHENIX detector is designed to perform a broad study of A-A, p-A, and p-p collisions to investigate nuclear matter under extreme conditions A wide variety of probes, sensitive to all timescales, are used to study systematic variations with species and energy as well as to measure the spin structure of the nucleon Designing for the needs of the heavy-ion and polarized-proton programs has produced a detector with unparalleled capabilities PHENIX measures electron and muon pairs, photons, and hadrons with excellent energy and momentum resolution The detector consists of a large number of subsystems that are discussed in other papers in this volume The overall design parameters of the detector are presented (C) 2002 Elsevier Science BV All rights reserved
