Brief view of Dataset
1. Field investigation
Hydrodynamics, suspended sediment concentration, and sediment particle size distribution were measured via four cruises shipboard in the mouth bar zone of the ME during the dry season of 2020. Eighteen gauging stations covering the mouth bar zone of the ME were observed during both the neap tide (26 October 2020) and spring tide (1 November 2020). The data from gauging stations #16, #17, and #18 during ebb and ebb-flood periods during the neap tide were the same. This directory contains the following datasets.
-data_current_velocity.xlsx: station number, time, longitudinal, latitude, x, y, depth observed from ADCP, depth of the last characteristic layer in the water column (depth_last_cell, m), depth of the first characteristic layer in the water column (depth_first_cell, m), and current velocity (cm/s) and direction (°) of six characteristic layers during spring and neap tides.
-data_salinity_turbidity_SSC.xlsx: station number, time, longitudinal, latitude, x, y, depth observed from ADCP, depth observed from OBS (depth_OBS_H), turbidity (ntu), salinity (psu), and suspended sediment concentration (SSC, mg/L) during spring and neap tides.
-data_particle_size_distribution.xlsx: station number, mean size (μm), suspended sediment size distribution of three characteristic layers, and bed sediment size distribution during spring and neap tides.
-data_river_discharge&water_level.xlsx: Hydrological conditions during investigation period during both neap and spring tides, i.e., river discharge at Makou station and tidal level at Sanzao station.
2. Idealized model results
Model settings and results of the idealized estuaries. The 'Grid_idealized_estuary.grd' and 'Grid_Enc_idealized_estuary.enc' are essential grid files for Delft3D-FLOW model. The scenarios with mouth bar and without mouth bar share the same grid file. 32 sites are set up in the central longitudinal section of the models to monitor the aggregate parameters in the longitudinal section near the outlet. The results of aggregate parameters are as follows.
(1) Idealized estuary with a mouth bar: The formats of the result files are 'mouthbar_XX_MDM(Site No.).mat'. The 'XX' consists of bed level, salinity, bed shear stress, sedimentcoh1 (i.e., cohesive suspended sediment concentration), and vertical and horizontal velocities.
(2) Idealized estuary without mouth bar: The formats of the result files are 'nobar_XX_MDM(Site No.).mat'. The 'XX' consists of bed level, salinity, bed shear stress, sedimentcoh1 (i.e., cohesive suspended sediment concentration), and horizontal and vertical velocities
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
