Late Paleoindian biface manufacture: a case study from the Mackenzie I site (DdJf-9) near Thunder Bay, Ontario
The Mackenzie Sites appear to form part of the Late Paleoindian Lakehead Complex that occupied the unglaciated peninsula between Glacial Lakes Agassiz and Minong during the terminal Pleistocene. A number of sites and isolated projectile point finds have been discovered throughout the region. Most excavated collections consist of quarry workshops, yielding vast lithic assemblages snapshots of the reduction sequence and very few diagnostic tools. In contrast Mackenzie I (DdJf-9) appears to be an extensive and repeatedly used stream mouth habitation site. Its vast lithic assemblage includes specimens attributable to the full range of the lithic reduction sequence and a large number of diagnostic tools. Biface assemblages from other sites within the Lakehead Complex have been analyzed in an attempt to determine the lithic reduction sequence. These sites have provided partial insight in understanding the middle stages of the Lakehead Complex reduction sequence. Mackenzie I offered the chance to observe the complete sequence of lithic reduction. The biface assemblage consists of 667 bifaces that could be placed in Stage 1-5 reduction. Am additional 223 bifaces were unstageable, 21 anomalous bifaces fell outside the normal range of variation, and 532 were classed as formal tools.
The biface stages were determined using metric and non-metric attributes in an attempt to further define the Lakehead Complex reduction sequence as previously established. Bifaces from Mackenzie I include Stage 1 through to Stage 6 (the last stage representing formal and diagnostic tools). It also became apparent that there were two trajectories of manufacture used in the production of the Mackenzie I assemblage. Large tabular blanks were reduced by systematic removal of flakes using direct percussion techniques, termed the Biface Trajectory. Where thin narrow flakes were reduced using refined methods of flake removal using either indirect percussion or directed pressure flaking, this was termed the the Flake/Blade Trajectory. It also became apparent that there was a selection of flake blanks, reduced for the specific purpose of manufacturing projectile points. Many of the projectiles at Mackenzie I exhibit a slight twist and/or curvature. Such attributes can be attributed to the nature of the blank and the subsequent methods of flake removal. Since the initial identification of the Lakehead Complex projectiles, they have been characterized by their refined parallel oblique flaking pattern. It was not until the excavation of Mackenzie I that the prevelance of this manner of flaking (99%) became apparent. This analysis has revealed that parallel oblique flaking enters the lithic reduction sequence at Stage 3, but with significantly wider flake scars. It is hypothesized that this was a result of the preferred lithic raw material. The Gunflint Formation cherts that were heavily utilized at Lakehead Complex sites are very hard, yet brittle and contain joint plane faults and iron-oxide inclusions. The Mackenzie I assemblage also indicates the presence of a blade technology being used alongside the bifacial toolkit. These blades are easily producible on high quality tabular blocks of the Gunflint Formation chert. It appears that blades, blade/flakes and large tabular blocks were all utilized in order to produce the Mackenzie I toolkit. These were all nearly exclusively finished using parallel oblique flaking techniques
Going Beyond Counting First Authors in Author Co-citation Analysis
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
“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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
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.
