Bringing together leading scholars of plague working across different historical periods, this book provides an inter-disciplinary study of plague in the city across time and space. The chapters cover a wide range of periods, geographical locations and disciplinary approaches but all seek to answer significant questions, including whether common motives can be identified, and how far knowledge about plague was based on an understanding of the urban space. It also examines how maps and photographs contribute to understanding plague in the city through exploring the ways in which the relationship between plague and the urban environment has been visualised, from the poisoned darts of plague winging their way towards their victims in the votive pictures from the Renaissance, to the mapping of the spread of disease in late nineteenth-century Bombay and photographing Honolulu’s great plague fire in 1900.\ud

Containing a series of studies that illuminate plague’s urban connection as a key social and political concern throughout history, Plague and the City is ideal for students of early modern history, and of the early modern city and plague more specifically
Visual Plague: The Emergence of Epidemic Photography
No full textHow epidemic photography during a global pandemic of bubonic plague contributed to the development of modern epidemiology and our concept of the “pandemic.” In Visual Plague, Christos Lynteris examines the emergence of epidemic photography during the third plague pandemic (1894–1959), a global pandemic of bubonic plague that led to over twelve million deaths. Unlike medical photography, epidemic photography was not exclusively, or even primarily, concerned with exposing the patient's body or medical examinations and operations. Instead, it played a key role in reconceptualizing infectious diseases by visualizing the “pandemic” as a new concept and structure of experience—one that frames and responds to the smallest local outbreak of an infectious disease as an event of global importance and consequence. As the third plague pandemic struck more and more countries, the international circulation of plague photographs in the press generated an unprecedented spectacle of imminent global threat. Nothing contributed to this sense of global interconnectedness, anticipation, and fear more than photography. Exploring the impact of epidemic photography at the time of its emergence, Lynteris highlights its entanglement with colonial politics, epistemologies, and aesthetics, as well as with major shifts in epidemiological thinking and public health practice. He explores the characteristics, uses, and impact of epidemic photography and how it differs from the general corpus of medical photography. The new photography was used not simply to visualize or illustrate a pandemic, but to articulate, respond to, and unsettle key questions of epidemiology and epidemic control, as well as to foster the notion of the “pandemic,” which continues to affect our lives today
Sulphuric Utopias: A History of Maritime Fumigation
No full textHow early twentieth century fumigation technologies transformed maritime quarantine practices and inspired utopian visions of disease-free global trade. In the late nineteenth and early twentieth centuries, fumigation technologies transformed global practices of maritime quarantine through chemical and engineering innovation. One of these technologies, the widely used Clayton machine, blasted sulphuric acid gas through a docked ship in an effort to eliminate pathogens, insects, and rats while leaving the cargo and the structure of the vessel unharmed, shortening its time in quarantine and minimizing the risk of importing infectious diseases. In Sulphuric Utopias, Lukas Engelmann and Christos Lynteris examine this overlooked but historically crucial practice at the intersection of epidemiology, hygiene, applied chemistry, and engineering. They show how maritime fumigation inspired utopian visions of disease-free trade to improve global shipping and to encourage universally applicable standards of sanitation and hygiene. Engelmann and Lynteris chart the history of ideas about fumigation, disinfection, and quarantine, and chronicle the development of the Clayton machine in 1880s New Orleans. Built by the Louisiana Board of Health and adapted and patented by Thomas Clayton, the machine offered a barrier against bacteria and pests and enabled a highway to global trade. Engelmann and Lynteris chronicle the Clayton machine's success and examine its competitors, including carbon-based fumigation methods in Germany and the Ottoman Empire as well as the “Sulfurozador” in Argentina. They follow the international standardization of maritime fumigation and explore the Clayton machine's decline after World War I, when visions of “sulphuric utopia” were replaced by a pragmatic acknowledgment of epidemiological complexity
Human Extinction and the Pandemic Imaginary
No full textThis book develops an examination and critique of human extinction as a result of the ‘next pandemic’ and turns attention towards the role of pandemic catastrophe in the renegotiation of what it means to be human. Nested in debates in anthropology, philosophy, social theory and global health, the book argues that fear of and fascination with the ‘next pandemic’ stem not so much from an anticipation of a biological extinction of the human species, as from an expectation of the loss of mastery over human/non-humanl relations. Christos Lynteris employs the notion of the ‘pandemic imaginary’ in order to understand the way in which pandemic-borne human extinction refashions our understanding of humanity and its place in the world. The book challenges us to think how cosmological, aesthetic, ontological and political aspects of pandemic catastrophe are intertwined. The chapters examine the vital entanglement of epidemiological studies, popular culture, modes of scientific visualisation, and pandemic preparedness campaigns. This volume will be relevant for scholars and advanced students of anthropology as well as global health, and for many others interested in catastrophe, the ‘end of the world’ and the (post)apocalyptic

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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

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
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.
