Geospatial Benchmark Land Cover Datasets (Raster)
No full textThis data is useful for benchmarking, comparing the performance of geospatial operations across array database systems. To make an accurate comparison each dataset has the same spatial extent, with increasing spatial resolution and total pixels. The increasing granularity of the data allows for accurate comparisons to be made across systems.Haynes, David. (2019). Geospatial Benchmark Land Cover Datasets (Raster).

One reason for the low use of these services is the difficulty in determining if a person is eligible for screening services, which requires calculating a smoking pack-year history. A gap in the literature is the lack of integrated smoking history data into a national dataset. We present the first dataset to estimate the number of individuals eligible for lung cancer screening by integrating in smoking history data. We develop a publicly available dataset that allows researchers to understand the estimated population eligible for lung cancer screening at the census tract level. Additionally, our approach allows for the understanding of the eligible population by age, gender, racial/ethnic grouping, and current or former smoking status. The dataset is flexible and allows for filtering of any age, gender, racial/ethnic category in addition to smoking status. This dataset will greatly enhance future programmatic efforts to identify and direct resources to communities that have the highest burden.National Cancer InsituteHaynes, David. (2023).

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Anterior vertebral stapling for the fusionless correction of scoliosis: Changes in motion stiffness following staple insertion and measurement of staple loading during movement
No full textTo address the need for effective surgical options in patients who are too young for fusion procedures 'fusionless' growth modulation treatments have been developed. The goal of these techniques is to harness the patient’s inherent spinal growth and redirect it to achieve correction, rather than progression, of the deformity. Currently there are several surgical treatments incorporating the fusionless ideology, one of which is anterior vertebral stapling. \ud
Recently clinical interest in stapling has increased following the release of a new staple designed specifically for insertion into the spine by Medtronic Sofamor Danek (Memphis., TN). These staples are manufactured using nitinol, a shape memory alloy (SMA) composed of nickel and titanium. Investigations using large animal models have shown these staples to be effective in modulating vertebral growth 1 and early results from a patient cohort have been promising. 2,3 Despite the increased clinical interest in the use of SMA staples little is known about the mechanism of their effect or the biomechanical consequences of their insertion on the immature spine.\ud
The aims of this study were threefold. Firstly, to measure changes in the bending stiffness of a single spinal motion segment following staple insertion. Secondly, to describe the staple forces that occur with spinal movement. Thirdly, to describe the vertebral structural changes that occur as a consequence of staple insertion.\ud
We propose however, that this effectiveness is not a consequence of unilateral compression of the vertebral physis, but rather that the insertion of an SMA staple causes vertebral hemiepiphysiodesis and subsequent convex growth arrest.\ud
Thoracic SMA stapling is a technique which has shown promising early clinical results. Based on our findings it is likely that, contrary to current beliefs, the clinical effect is due to vertebral hemiepiphysiodesis causing convex growth arrest
