    The 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

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Measuring Intensity – Describing and Analysing the “Urban Buzz”

    Density or Intensity?There is much debate about how to measure density – dwellings per hectare, bedrooms per hectare or people per hectare; including or excluding major highways, parks and open spaces; the permanent population only or the transient one too?While this gives urban planners something to disagree about it risks missing the point: great urban places are not created by density; they are created by intensity.And the difference matters. When people describe the buzz of a marketplace they do not say, “Wow - it was so dense!”. They are much more likely to say how intense it was. Density is a word used by planners. Intensity is a word that real people use, and perhaps because it describes the outcomes that people experience rather than the inputs that have gone in to creating them. It is the outcomes that are ultimately more important. But planning professionals like density. Even though density fails to capture the essence of what it feels like to be somewhere, the term appeals to professional instincts. It describes the raw ingredients that planners have to handle and, once you choose which version of the formula you are going to use, density is easy to measure. It involves a simple calculation of straightforward urban quantities such as the number of people, the number of houses or the number of bedrooms, all divided by the geographic area over which those ingredients occur. Easy.In contrast, intensity seems more difficult to pin down, not least because it appears to have a subjectively emotional dimension; it speaks of feelings, of responses, of stimuli, and this raises problems about how it can be effectively measured. But intensity is also a response to context, to place and above all to people - and here we can find clues to its measurement.Observing IntensitySo what are the factors that people are responding to when they instinctively feel the intensity of a great place? For a start, they can not be calculating a planner’s measure of urban density because, even if they were so minded, they could not possibly know about populations and geographic areas when they are walking along a street or sitting at a café table on a public space.What people can respond to though is what is happening around them in the public realm: they can see how many other people there are, and they can see what these people are up to. In other words, intensity is obvious, immediate and instinctively calculable to the person in the street: not only the mobile population of walkers, drivers and cyclists but also the immobile population of sitters, leaners and pausers. Intensity has a static as well as a kinetic dimension. Indeed the stationary people are the essential ingredient of intensity. They are the people who have chosen to be there, to add to the place through their semi-permanence and not simply to pass through on the way to somewhere else. Intensity is not therefore about the population density of an area but the population that is participating in the public realm of an area. And this should be obvious. And everyday. But any attempt to emphasise the benefits of static participation runs counter to the mindset of the traffic engineer and counter to the still-persuasive, kinetic legacy of Le Corbusier, who described “grinding gears and burning gasoline” as the pleasurable objectives of the Plan Voisin.Nevertheless, intense places are sticky places and especially so when people are not only co-present in space but when they are also interacting: talking to each other, sharing thoughts, ideas, opinions. This is the essence of intensity; there is an exchange - a transaction – be it economic, social, cultural, intellectual, factual or simply facile. It is the daily public life of every thriving village, town and city. It is so apparently unremarkable as to go unnoticed, unobserved and unmeasured. Until it is not there. And that is when you feel it most clearly.A number of years ago my colleagues at Space Syntax were working on a sample of towns across the UK, some historic and some new. The towns had similar residential populations and similar retail floorspace provisions across similar geographical areas; in other words, similar densities. But what the team had also done was to count the numbers of people using the centres of each town: how many were walking and sitting in public space. They had counted over several days, from morning until evening. What they found was that the historic towns consistently had many more people using their centres than the new ones - and they knew from other evidence that the historic towns had stronger economic performances. Here then were places with similar urban densities but different intensities of human activity.What seemed to explain the differences between historic and new towns were first, the spatial layout and second, the street design of each place. The historic towns were laid out around radial streets that were designed to carry cars as well as vehicles and which met at the centre of the town in a public space. Behind these radial streets were more or less continuously connected grids of residential streets, interrupted by the occasional large open space. Both cars and pedestrians could use the residential streets, while the open spaces were generally for pedestrians only. There was some limited pedestrianisation in the very centre of each town.In contrast, the new towns often had separate street networks for vehicles and pedestrians, no high street or central public space and usually one or two enclosed shopping malls. Their central areas were typically pedestrianised and spatially separated from the surrounding residential areas by a vehicle-only ring road; these residential areas were separated from each other by large swathes of open space.To summarise, the key differences were first in the intensity of the human experience and second in the design of the street network. Intensity, it seems, is facilitated by an alignment of physical and spatial factors: having the movement-sensitive land uses on sufficiently well-connected streets that are, in the main, shared by vehicles and pedestrians.Measuring IntensityImportantly, both the amount of human activity and the degree of street connectivity are measurable commodities – if you know how. This is the professional specialism of my practice, Space Syntax, and it has two key parts: one part that takes place in the studio, using purpose-designed software that measures the amount of connectivity in street grids and the other part that happens on site using some form of counting device. This device may be a camera strapped to a lamp post or, in recent years, a drone flight. Or it may simply be a set of human eyes, a pencil and a notepad. Onto these ‘foundational’ datasets are added other information, which might be about air quality, land value, crime rates or health outcomes. Statistical software is employed to explore relations between the datasets: how is health or wealth or educational achievement related to spatial connectivity or isolation? The product of this process is an Integrated Urban Model: a quantitative record of urban form and urban performance. A Geographical Information System is used to hold the datasets in one place and a basic form of artificial intelligence is run to explore the links between the data.However it is possible to create a primitive version of a data platform using only PowerPoint and Excel. After all, Space Syntax began its work before the Macintosh, before colour screens, before the internet, before CAD, before GIS and long before BIM. Its observations of pedestrian movements around Trafalgar Square were done with pen and paper, the results coded manually into a simple drawing programme.What matters today is what mattered then: to bring data to life using maps and colours rather than spreadsheets and charts. To make it accessible to the audiences that will be making judgments about the future of places: investors, planning officers, politicians and local communities. Measures of intensity therefore need to speak to multiple audiences and not least to the design community, into whose creative hands is entrusted the responsibility for shaping the aspirations of stakeholders. An Integrated Urban Model must be nimble, capable of responding again and again to the short and intensive programme of a rapid design process. Beware the Smart City “Control Room” stuffed with technicians; eintegratedmbrace instead a portable platform that can respond to the timescale of a creative whim.Creating a Profession of “Urban Intensity Surveyors”So why do we not measure towns and cities in such a systematic way? Why is there not a profession of urban intensity surveyors? And a culture among architects and urban planners of designing for intense human interactions?The problems start when the responsibility for thinking about cities, streets and public spaces moves from the individual enjoying the buzz of the boulevard to the collective of professional institutes charged with creating place. Density prevails over intensity and we revert to simplifications. Assumptions are made - incorrectly as we have seen - that the quality of street life will be in direct proportion to the density of people in an area. That if we have more people then the streets will be busier and the busier the streets, the better the place. But then the counter view is quite reasonably made that people need quiet streets and so densities should not be too high. And a compromise is eventually reached for neither super high nor super low densities; neither towns that are too big nor too small. And if we need big towns then they should be broken up into manageable parcels. Since we want pedestrians then we should pedestrianise.We end up with an urbanism of averages and a morphology of enclaves through an approach that is much too simplistic to ever create great place. It is not born of science and it does not reflect human experience: people know instinctively that you can turn off the busiest street in the city and immediately find yourself on a lane that is one of the quietest; that the intensity of the urban experience can transform itself in seconds. This is one of the great joys of exploring great cities: they are not pervasively busy; they are intensely quiet as well. They have a foreground grid of busy streets and a background grid of quiet ones. If we can systematically measure urban intensity then we will understand how towns and cities work in ways that will transform practice. And by transforming practice we will transform place.The Future for IntensityThe professions will be unwise to avoid the opportunities presented by technology. Both the technologies of data capture, visualisation and analysis as well as the technologies that are affecting human behaviours: broadband, social media, augmented reality (AR) and artificial intelligence (AI). Human activity is becoming ever more intense and this gives us another reason to systematically measure urban intensity. People are walking more slowly, ensconced in virtual worlds at the same time as participating in physical space; seeing their surroundings augmented with pop-up information. The trend will continue as AR on our smartphones becomes AR on our spectacles. As well as talking to each other we will be talking to objects on display in shops, to screens in buildings and on streets, and to ourselves – our digital twin may appear as an avatar walking alongside us in our peripheral vision or in front of us when trying on clothes for us. This intensity of communication can already be seen in early adopting countries, especially China, and it may seem strange at first. But there was a time, not long ago, when it seemed strangely ostentatious to put down a mobile phone on a table in a public place.The brain has a finite processing capacity and so what goes into handling increased visual information will have to be taken away from the control of bodily function. People may therefore adapt to the amplified intensity of visual stimuli by moving ever more slowly. We will need more space for these intense activities and the obvious place is the street, where we will need more space for people. Road space will have to narrow and footways will have to widen. We will need more places to sit and lean - to be sticky.And this presents a choice for designers: continue to disagree about the best way to measure density or embrace intensity and anticipate the radical transformation of place

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
