Peter Logan: Victorian Fetishism [Audio interview]
No full textPeter Logan is the author of Nerves and Narratives: A Cultural History of Hysteria in Nineteenth-Century British Prose (1997) and, more recently, Victorian Fetishism: Intellectuals and Primitives (2009). On May 15, 2012, Fred Rowland interviewed Peter Logan to discuss Victorian Fetishism, which details the development of ideas about the primitive and how these concepts set the boundaries of culture in Victorian Britain. Drawing from Lucretius, Vico, and Auguste Comte, Peter Logan explains how fetishism – the defining feature of culture’s absence – figured in the works of literary and cultural critic Matthew Arnold, realist novelist George Eliot, and anthropologist Edward Tylor.Temple University.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Two systems, a pulsed acoustic radar (acdar) and an array of ground level pressure sensors, were tested. Site restrictions limited the Logan work to preliminary evaluation. The tests at Kennedy Airport established the general operating characteristics of both tracking systems. It was found that the acoustic sensor can detect and track the vortices of all commonly used commercial aircraft with varying degrees of sensitivity. Pressure sensors generally behaved best during conditions of low to moderate winds when the vortices could often be tracked laterally up to several hundred feet from the aircraft path. (Author

William Logan Fisher was an industrialist and author of religious texts. He was raised at the “Wakefield” estate (built 1798; northeast corner of Ogontz and Lindley Avenues), which he would inherit from his father in 1807. His first wife, Mary Rodman Fisher, died in 1813 at the age of 32. He was remarried in 1817 to Sarah Lindley, a daughter of Quaker ministers Jacob and Ruth-Anna Lindley of Chester County. Fisher purchased artist Charles Willson Peale’s “Belfield” estate in 1826. La Salle University acquired the property in 1984, after which time these portraits hung in the “Peale House” for many years.
The lives of Fisher descendants that occupied properties on and around La Salle’s campus have been heavily researched by La Salle University students and faculty. The Wister Family Special Collection in the Connelly Library includes written accounts, archival photographs, and other primary documents available for study, and also serves as a repository of student work around these topics. These resources complement the Art Museum’s holdings of works by the Peale family and other local artists. Classes have used both collections simultaneously for projects.

Understanding the landscape of adversarial robustness
No full textThis electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2019Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 108-115).Despite their performance on standard tasks in computer vision, natural language processing and voice recognition, state-of-the-art models are pervasively vulnerable to adversarial examples. Adversarial examples are inputs that have been slightly perturbed--such that the semantic content is the same--as to cause malicious behavior in a classifier. The study of adversarial robustness has so far largely focused on perturbations bound in l[subscript p]-norms, in the case where the attacker knows the full model and controls exactly what input is sent to the classifier. However, this threat model is unrealistic in many respects. Models are vulnerable to classes of slight perturbations that are not captured by l[subscript p] bounds, adversaries realistically often will not have full model access, and in the physical world it is not possible to exactly control what image is sent to the classifier. In our exploration we successfully develop new algorithms and frameworks for exploiting vulnerabilities even in restricted threat models. We find that models are highly vulnerable to adversarial examples in these more realistic threat models, highlighting the necessity of further research to attain models that are truly robust and reliable.by Logan Engstrom.M.

Improved quantification of Chinese carbon fluxes using CO2/CO correlations in Asian outflow
No full text[1] We use observed CO2:CO correlations in Asian outflow from the TRACE-P aircraft campaign (February–April 2001), together with a three-dimensional global chemical transport model (GEOS-CHEM), to constrain specific components of the east Asian CO2 budget including, in particular, Chinese emissions. The CO2/CO emission ratio varies with the source of CO2 (different combustion types versus the terrestrial biosphere) and provides a characteristic signature of source regions and source type. Observed CO2/CO correlation slopes in east Asian boundary layer outflow display distinct regional signatures ranging from 10–20 mol/mol (outflow from northeast China) to 80 mol/mol (over Japan). Model simulations using best a priori estimates of regional CO2 and CO sources from Streets et al. [2003] (anthropogenic), the CASA model (biospheric), and Duncan et al. [2003] (biomass burning) overestimate CO2 concentrations and CO2/CO slopes in the boundary layer outflow. Constraints from the CO2/CO slopes indicate that this must arise from an overestimate of the modeled regional net biospheric CO2 flux. Our corrected best estimate of the net biospheric source of CO2 from China for March–April 2001 is 3200 Gg C/d, which represents a 45 % reduction of the net flux from the CASA model. Previous analyses of the TRACE-P data had found that anthropogenic Chinese C
