Replication Data for: Sea-level variability and vertical land motions in Singapore from tide gauge and GNSS observations
No full textThis dataset contains the vertical position time series from 15 Global Navigation Satellite System (GNSS) stations in Singapore. They include one International GNSS Service (IGS) station (NTUS), one station (SING) maintained by the Earth Observatory of Singapore, and 10 stations from the Singapore Satellite Positioning Reference Network (SiReNT), which is a network operated by the Singapore Land Authority. Five stations (SLOY, SNTU, SNYP, SKEP and SSEK) are no longer operational. SLOY, SNTU and SNYP have been relocated and are now known as SLYG, SNYU and SNPT, respectively. The dataset is produced in the paper titled “Sea-level variability and vertical land motions in Singapore from tide gauge and GNSS observations”
Replication Data for: Coseismic and Postseismic Slip of the 2005 Mw 8.6 Nias‐Simeulue Earthquake: Spatial Overlap and Localized Viscoelastic Flow
No full textThis repository provides the coseismic slip and afterslip models for the 2005 Mw 8.6 Nias-Simeulue earthquake
Replication Data for: Diverse slip behavior of the Banyak Islands subsegment of the Sunda megathrust in Sumatra, Indonesia
No full textThis repository provides data that are necessary to reproduce the results and figures in the paper titled "Diverse slip behavior of the Banyak Islands subsegment of the Sunda megathrust in Sumatra, Indonesia".
(1) This repository contains two new datasets: a dataset of the coral measurements taken within the Banyak Islands from 2005 to 2010 (Dataset S1), and our preferred coseismic slip model for the 6 April 2010 Mw 7.8 Banyak Islands earthquake (Dataset S2).
(2) This repository also provides input files to Georgia Tech Ground Deformation Software (GTDef), which was used in the paper for modelling the Banyak Islands earthquake and for conducting the checkerboard resolution test. Selected output files that contain the preferred models are also provided. GTDef code can be downloaded from http://geophysics.eas.gatech.edu/anewman/classes/MGM/GTdef/.

Replication Data for: Active subduction and strain partitioning in western Myanmar revealed by a dense survey GNSS network
No full textThis repository contains the data and code necessary to reproduce the results in the paper titled “Active subduction and strain partitioning in western Myanmar revealed by a dense survey GNSS network”.
In particular, it contains:
1. Raw GNSS observations (RINEX format) for all sites surveyed in Myanmar between 2016 and 2020, and the metadata (antenna & receiver information, height, GAMIT processing tables, and survey logs) required to process them.
2. The processed timeseries (GAMIT .pos format) for both survey and continuous GNSS sites that were processed as part of this work. The timeseries also include the positions for surveys conducted prior to our work. All timeseries are reported in the ITRF2014 reference frame.
3. The interseismic velocities estimated for each site with sufficient timeseries observations, including survey, continuous and previously published sites in the region. The velocities are reported in 3 reference frames: ITRF2014, relative to the Sunda plate, and relative to the Burma (Myanmar) microplate, as described in the text.
4. Block modeling input files including the modeled fault network and a 3D fault mesh for the Rakhine-Bangladesh megathrust, analysis scripts, and output results for the three block models reported in the text
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
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
