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
Assessment of Ma-a creek along Purok Kapundok : basis for diversion and design improvement
No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Civil EngineeringClayey soils pose a risk and damage to life and property and are unsuitable for direct engineering application due to their shrink-swell behavior. Pavement cracks and swells are some effects due to soil excessive distress under volumetric changes of its underlying soil. With this, researchers explore different methods to stabilize expansive soils using fibers and cementitious materials. This paper used Kapok Fiber (KF) and Bamboo Leaves Ash (BLA) as soil stabilizers. It seeks to determine the soil classification, test its effects on compaction, investigate the swelling of the soil and change of consistency. Varying concentrations are 0.5% KF and 6%BLA, 0.8% KF and 6%BLA, and 1% KF and 6%BLA by weight of the soil. Test samples undergo sieve analysis, Atterberg limit, compaction, and swell index test. Results revealed that adding fibers to the soil matrix increases
maximum dry density (MDD) while optimum moisture content (OMC) varies indirectly. In addition, soil swelling decreases after adding KF and BLA with an optimum design mix of 0.5% KF and 6%BLA. T-test showed that swell index under 10, 30, and 65 blows significantly differ between the control and the optimum ratio. Furthermore, the consistency of the soil changes from highly plastic to low plasticity. Therefore, KF and
BLA are good sources of soil stabilizers for pavement subgrade purposes
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
basis for diversion and design improvement
No full textIn Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Civil EngineeringFlooding has been a national concern in the Philippines, with high chances to occur during typhoons and may happen in the future due to rapid urban development. Flood risk reduction strategies can be enhanced by a diversion channel, increasing the waterway's capacity, or a closed diversion canal. The assessment of Maa Creek along Purok Kapundok: the basis for diversion or design improvement is a critical study that assesses the current state of the creek and the measures that can be taken to mitigate or reduce the flood discharge, even so, improve the functionality of the vicinity. The study gathered essential data, including the creek's geometry and dimensions, water flow data, and more. Following, HEC-RAS is utilized to simulate and compare the existing channel and the proposed diversion channel. The results of HEC-RAS steady flow modeling found that a diversion shortcut will further increase the water flow, thus, reducing the water elevation. Also, incorporating culverts in the diversion will add to the area's functionality. Simulating the flow that is critical for the creek, gathered hydrological data from the year 2018 is used for the unsteady flow. Here, it is found that water surface elevation reaches up to 3.12 meters high. In addition, results from sediment analysis of the proposed diversion show that invert siltation will increase by 0.95 meters in 1 year. In conclusion, a diversion shortcut with culverts reduces water surface elevation because of improved water discharge. Nevertheless, the design capacity is enough, and the future capacity may be reduced due to the siltation. It is essential to conduct regular monitoring and assessment of sediment build-up to sustain the correct water depth and prevent flooding
