    A citation analysis of the ICER 2005-07 proceedings

    Full text link
    This paper identifies the most commonly cited conferences, journals and books of the 43 papers within the first three ICER proceedings. A large array of conferences, journals, and books were cited. However, only a small set of journals and conferences were cited frequently, and the majority were only cited within a single paper, which is consistent with a power law distribution, as predicted by Zipf's Law. The most commonly cited books are concerned with education in general (29%) or psychology (20%), while 17% of books are concerned with computer science education and 12% with computing content. The citation results for ICER are contrasted with earlier published citation analyses of SIGCSE 2007 and ACE2005-07. © 2009, Australian Computer Society, Inc

    From Artificial Intelligence (AI) to Intelligence Augmentation (IA): Design Principles, Potential Risks, and Emerging Issues

    We typically think of artificial intelligence (AI) as focusing on empowering machines with human capabilities so that they can function on their own, but, in truth, much of AI focuses on intelligence augmentation (IA), which is to augment human capabilities. We propose a framework for designing intelligent augmentation (IA) systems and it addresses six central questions about IA: why, what, who/whom, how, when, and where. To address the how aspect, we introduce four guiding principles: simplification, interpretability, human-centeredness, and ethics. The what aspect includes an IA architecture that goes beyond the direct interactions between humans and machines by introducing their indirect relationships through data and domain. The architecture also points to the directions for operationalizing the IA design simplification principle. We further identify some potential risks and emerging issues in IA design and development to suggest new questions for future IA research and to foster its positive impact on humanity

    REDISCOVERY OF A NATIVE AMERICAN CULTURAL LANDSCAPE: THE CHICKASAW HOMELAND AT REMOVAL

    Little information beyond generalities exists regarding the cultural landscape of the Chickasaw Indians in their ancestral homelands prior to Removal in the late 1830s. This dissertation evaluates one possible archival source for specifics of Chickasaw land use, the field notes and survey plats compiled as part of the Public Land Survey System (PLSS). The process of original survey following land cession treaty divided the ceded area up into the familiar square-mile rectangular system of townships and ranges that extends from the Mississippi Territory westwards, in the so-called public land states. The research compiles all cultural observations made by the surveyors within a fourteen township area (totaling 504 square miles). This study area, generally located on the west bank of Town Creek between present-day Tupelo and Pontotoc MS, was chosen to cover the traditional center of Chickasaw settlement and elements of important roads such as the Natchez Trace. The resulting catalog of observations was compared to similar features on the township plats and to other cultural resource inventories to identify patterns of inscription and possible erasure of Native American cultural activities. Geographic Information Systems (GIS) technology was used to consolidate and compare these data resources. The PLSS survey documents provide a useful but not complete resource for identifying Chickasaw cultural presence within the study area. No consistent pattern of omission or erasure of Chickasaw activities was identified. The analysis identifies several opportunities and caveats for future researchers who might extend this analysis, including technical challenges in applying GIS technology to this data

    Seismic wave propagation in Iran and eastern Indian shield

    This dissertation addresses several important aspects of observational earthquake seismology: 1) methods for data management and processing large datasets, 2) analysis of seismic wave propagation at local to regional (up to about 700 km) source-receiver distances, 3) analysis of seismic coda, and 4) critical re-evaluation of the fundamental problem of seismic wave attenuation and measurement of the seismic “quality” factor (Q). These studies are carried out using new and previously analyzed earthquake data from Iran. In each of the four application areas above, innovative methods are used and significant new results are obtained. First, for efficient managing and processing of large earthquake datasets, I use a flexible, exploration-style open-source seismic processing system. Custom and problem-oriented scripts using Matlab or Octave software are included as tools in this processing system, allowing interactive and non-interactive analysis of earthquake records. In the second application, I note that the existing models for body-wave amplitudes are hampered by several difficulties, such as inaccurate accounts for the contributions of source and receiver effects and insufficient accuracy at the transition between the local and regional distances. Finding a reliable model for body-wave amplitudes is critical for many studies. To achieve such a reliable model, I use a joint inversion method based on a new parameterization of seismic attenuation and additional constraints on model quality. The joint inversion provides a correct model for geometrical spreading and attenuation. The geometrical-spreading model reveals the existence of an increase of body S wave amplitudes from 90 to about 115 km from the source which might be caused by waves reflecting from the crust‐mantle boundary. Outside of this distance range, amplitude decays are significantly faster than usually assumed in similar models. Third, in two chapters of this dissertation devoted to coda studies, I consider the concept of the frequency-dependent coda Q (Qc). Although this quantity is usually attributed to the subsurface, I argue that because of subjective selections of model assumptions and algorithms, Qc cannot be rigorously viewed as a function of surface or subsurface points. Also, frequency dependence of the measured Qc strongly trades off with the subjectively selected parameters of the measurement procedure. To mitigate these problems, instead of mapping a hypothetical in-situ Qc, I obtain maps of physically justified parameters of the subsurface: exponents of geometrical spreading (denoted ) and effective attenuation (denoted qe). For the areas of this study, parameter ranges from 0.005 s-1 to 0.05 s-1 (within Zagros area of Iran) and 0.010 s-1 to 0.013 s-1 (within the eastern Indian Shield). Finally, from both body- and coda-wave studies, I derive estimates of seismic attenuation within the study areas. In two areas of Iran and within the Indian Shield, weak attenuation with Q-factors of 2000–6000 or higher is found. In particular, coda envelopes can be explained by wave reverberations within elastic crustal structures, and the Q-type attenuation appears undetectable

    This open access book shows how figures, figuring, and configuration are used to understand complex, contemporary problems. Figures are images, numbers, diagrams, data and datasets, turns-of-phrase, and representations. Contributors reflect on the history of figures as they have transformed disciplines and fields of study, and how methods of figuring and configuring have been integral to practices of description, computation, creation, criticism and political action. They do this by following figures across fields of social science, medicine, art, literature, media, politics, philosophy, history, anthropology, and science and technology studies. Readers will encounter figures as various as Je Suis Charlie, #MeToo, social media personae, gardeners, asthmatic children, systems configuration management and cloud computing – all demonstrate the methodological utility and contemporary relevance of thinking with figures. This book serves as a critical guide to a world of figures and a creative invitation to “go figure!
