INTERFACES. A program for determining the 3D structures of surfaces sites using NMR data
Full text linkDynamic nuclear polarization surface enhanced NMR spectroscopy has enabled the determination of high-resolution structures from surface-supported molecules, including single-site heterogeneous catalysts. Structure determinations have largely mimicked the approaches used in biomolecular NMR spectroscopy, namely, using distance measurements to constrain a conformational search. These early demonstrations made use of purpose-built software, which has limited the adoption of the technique. Herein, we describe the open-source program INTERFACES (Interpret NMR to Elucidate or Reconstruct the Full Atomistic Configurations of External Surfaces) which automates the analysis of RE(SP)DOR data as well as the structure determination for surface sites. Distances, angles, dihedral angles, complex orientation, and distance from the support can all be sampled to find all structures that agree with the experimental data. A χ2 metric is used to define the error ranges of the REDOR fits and produce structures with an arbitrary level of confidence. Structural solutions are then provided as both overlays and ORTEP-like probability ellipsoids.This article is published as Cunningham, James, and Frédéric A. Perras. "INTERFACES.

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
Access all
No full textAccess All was performance produced following a three-month mentorship in web-based performance that I was commissioned to conduct for the performance company Igneous. This live, triple-site performance event for three performers in three remote venues was specifically designed for presentation at Access Grid Nodes - conference rooms located around the globe equipped with a high end, open source computer teleconferencing technology that allowed multiple nodes to cross-connect with each other. Whilst each room was setup somewhat differently they all deployed the same basic infrastructre of multiple projectors, cameras, and sound as well as a reconfigurable floorspace. At that time these relatively formal setups imposed a clear series of limitations in terms of software capabilities and basic infrastructure and so there was much interest in understanding how far its capabilities might be pushed.----- \ud
Numerous performance experiments were undertaken between three Access Grid nodes in QUT Brisbane, VISLAB Sydney and Manchester Supercomputing Centre, England, culminating in the public performance staged simultaneously between the sites with local audiences at each venue and others online. Access All was devised in collaboration with interdisciplinary performance company Bonemap, Kelli Dipple (Interarts curator, Tate Modern London) and Mike Stubbs British curator and Director of FACT (Liverpool).----- \ud
This period of research and development was instigated and shaped by a public lecture I had earlier delivered in Sydney for the ‘Global Access Grid Network, Super Computing Global Conference’ entitled 'Performance Practice across Electronic Networks'. The findings of this work went on to inform numerous future networked and performative works produced from 2002 onwards

Summarized by Leigh Waterbury
James Cunningham was born in the Bronx in 1918 and describes what life was like in his household and his neighborhood. His father was a light-skinned black man who was considered colored while in WWI, and later when he moved to New York City to work as a customs inspector he was able to pass as white, which likely helped him to acquire that position. James attended PS 23 elementary school in his neighborhood around 167th street, where he was the only boy of color in the whole school. He explains that while growing up, skin color was never really something that was focused on in his household, and also was not an issue in the community either. His mother raised him and his four younger siblings to be focused on family and education rather than anything race related. Although he was the only boy of color in his elementary school and very much the minority in junior high PS 51 as well as Morris High School, he never really felt a sense of racial hostility until an experience while attending Morris. There was a dance class being offered and when he tried to sign up for the class he was told that all colored people were born natural dancers so therefore he did not need to take lessons and could not be in the class. This was his first experience being racially identified.
As for his experience in the home it was a bit of a sheltered one. His mother was a member of the Women’s Christian Temperance Union and thought that music was related to the devil so it was not really allowed in the home. He did get to experience the jazz era and musicians like Duke Ellington and Louis Armstrong by listening to radio programs and going to shows with a friend. Politics were also not discussed in the household. His fathers’ political theory was that he was Republican and going to remain that way because Lincoln was Republican and he freed the slaves. During the Depression his family was not very much affected because his father had a government job with a reliable income, but he did notice indications of suffering in the community.
Margaret Cunningham, James’ wife, was born and raised in Brooklyn in the Bedford-Stuyvesant community, and experienced a much different upbringing than James. She grew up in a predominantly black community and was always conscious of her race and Black culture. She does not really recall many racial prejudices, but she does not remember having white friends or really being around that community too much. Although the two were from New York City, they met in Washington DC. Both described living in DC as being much more segregated. Margaret described the segregation on buses and public places as well as the difficulty for a black person to be promoted even though they were just as qualified. For James it was a very different experience from what he was used to in the Bronx, since he never really dealt with those issues growing up
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
