KIC 8462852: THE INFRARED FLUX
Full text linkWe analyzed the warm Spitzer/IRAC data of KIC 8462852. We found no evidence of infrared excess at 3.6 μm and a small excess of 0.43 ± 0.18 mJy at 4.5 μm below the 3σ threshold necessary to claim a detection. The lack of strong infrared excess 2 years after the events responsible for the unusual light curve observed by Kepler further disfavors the scenarios involving a catastrophic collision in a KIC 8462852 asteroid belt, a giant impact disrupting a planet in the system or a population of dust-enshrouded planetesimals. The scenario invoking the fragmentation of a family of comets on a highly elliptical orbit is instead consistent with the lack of strong infrared excess found by our analysis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Circle Nine by A. Hetzel
No full textHeltzel, Anne. Circle Nine. Somerville, Mass.: Candlewick Press, 2011. Print. Why are hapless females in YA novels always named Abby? I don’t know, the amnesiac narrator of Circle Nine would reply. That’s just what it says on my necklace. So begins Anne Heltzel’s debut thriller: a teenaged girl awakens on the pavement outside a burning building with no memories and no name, save the one she wears in gold around her neck. With her is a mysterious, charismatic youth named Sam, who claims to be her friend. Sam persuades Abby to retreat from the fire and into the woods, where they hide in the safety of his “cave-palace”: a glittering subterranean paradise full of shimmering fabrics and sumptuous furniture. There, the two of them sip pomegranate wine, discuss fine literature, and forswear all contact with the outside world, which Sam likens to an Aleghierian hell (hence the book’s title). We suspect this a fantasy, invented by Abby to protect herself from an uglier cave and an uglier Sam, to say nothing of the ugly events occluded by her smoke-kippered memory. The question is: whose fantasy is it? What sixteen-year-old with cheap bling on her neck would retreat into a happy place wrought with literary allusion, Platonic cave metaphors, and Oriental carpets? This is clearly the reverie of the author herself, still in love with her various muses. Abby’s fantasyland, though out of character, is not necessarily a detriment to the novel itself. Indeed, we could do without the predictable combination of flashbacks and sleuthing by which Abby reconstructs her true identity, and abide instead within her doomed and darkly luminous otherworld. For it is there that Heltzel’s storytelling is at its boldest, her writing most sensuous and wild, and it is here that the novel promises—if only briefly—to be something other than the dreary chestnut about a naïve girl brought low by bad luck and sly men.Recommended with reservations: 2 out of 4 starsReviewer: Sarah Mead-Willis Sarah is the Rare Book Cataloguer at the University of Alberta\u27s Bruce Peel Special Collections Library.

The Honeybee Man by L. Nargi
No full textNargi, Lela. The Honeybee Man. Illus. Kyrsten Brooker. New York: Schwartz & Wade, 2011. Print. This charming picture book chronicles the unconventional cottage industry of Fred, a Brooklynite who spends his spare time tending three colonies of honeybees housed on the roof of his townhouse. As the day unfolds, we follow Fred’s bees as they fan out across the borough, bringing back nectar from the herb gardens, flower pots, and even wild blueberry bushes flowering therein. Fred then harvests the honey and distributes jars of it to his neighbours. With this growing popularity of urban agriculture (and urban apiculture), Nargi’s story is a timely one, clearly aimed at progressive young families interested in the connection between local ecology and human community. The book is transparently but not disagreeably didactic: bee behaviour is examined and explained (both within the context of the story and in a two-page appendix), and the processes of beekeeping and honeymaking are illuminated through Fred’s perambulations within his apartment-cum-apiary. Brooker’s illustrations, a combination of gestural painting and collage, have a patchwork, handmade quality well suited to the book’s overarching preoccupation with all things organic and homespun. Her renderings of Brooklyn’s brownstone vistas are simple in their bright, flat planes of colour, but also satisfyingly dense with decoupaged texture and detail. Like the honey made by Fred’s “tireless Brooklyn bees,” her artwork is both a concentration - and a sweetening - of the teeming heterogeneity of urban life.Highly recommended: 4 out of 4 stars Reviewer: Sarah Mead-Willis Sarah is the Rare Book Cataloguer at the University of Alberta\u27s Bruce Peel Special Collections Library.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
