This species occurs in slightly acidic water (pH: 6.25±0.12) with phosphates 0.06± 0.02 mg l -1; nitrates: 0.55± 0.13 mg l -1 and dissolved oxygen 3.95± 0.55 mg l-1.</p> <p> <b>Distribution:</b> —Currently known only from the type locality.</p> <p> <b>Etymology:</b> —Named after the country name, India.</p> <p> <b>Observations:</b> —In the SEM the valve has irregular areolae that occur across the face (Figs 2–A, B, C) and extend onto the mantle (Fig. 2–E). Two, rarely three (Fig. 2–B) ocelli are present. Ocelli are ellipticalelongate in shape and the porelli that comprise the ocelli are small and radiate in their organization (Figs 2–A, B, F). Internally, ocelli appear as depressions at the valve face/mantle junction (Figs 2–C, D). Rimportulae have round openings externally (Figs 2–A, B). Internally they are elevated and lip-like (Figs 2–G, H). There is a c–shaped depression around the rimportula internally (Fig. H). The girdle is wide, and copulae possess distinct pores.</p> <p> <i>Pleurosira indica</i> differs from <i>P.laevis</i> (Ehrenb.) Compère by the presence of irregularly arranged areolae and presence of c–shaped depression around the rimoportulae. <i>Pleurosira laevis</i> (Fig. 1 in Compère 1982, Fig. 2–A in Kociolek <i>et al.</i> 1983) shows a clear pattern in areolae arrangement with striae radiating from the centre to margin and a silica surface which separate the porelli from areolae (Fig. 4 in Compère 1982) is also absent in <i>P. indica. Pleurosira indica</i> can be easily distinguished from <i>P. soctrensis</i> var. <i>pangeroni</i> Compère (Figs 33–36, 44 in Compère 1982) by valve outline and absence of a c–shaped depression around each rimportula. <i>Pleurosira soctrensis</i> var. <i>pangeroni</i> has also been reported from South India (Compère 1982). <i>Pleurosira indica</i> also differs from another Indian taxon, <i>Pleurosira socotrensis</i> var. <i>bengalensis</i> Compère (Figs 37, 38, 44 in Compère 1982), by the absence of the 6–15 labiate processes being arranged in a circular fashion.</p> <p>Order Thalassiosirales Glezer & Makarova 1986</p> <p>Family Thalassiosiraceae Lebour 1930</p> <p> Genus <i>Spicaticribra</i> Johansen, P.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Social Media Monitoring Of Airbnb Reviews Using AI: A Sentiment Analysis Approach For Immigrant Perspectives In The UK
No full textThis paper presents a novel approach for monitoring social media content related to Airbnb reviews, explicitly focusing on the sentiments expressed by immigrants in the United Kingdom. The proposed system, a Quick Search System, leverages machine learning techniques to perform sentiment analysis on many Airbnb reviews. The system aims to provide timely and insightful information about the experiences and sentiments of immigrants in the UK, as reflected in their Airbnb reviews. By employing state-of-the-art machine learning algorithms, the system enables efficient and accurate sentiment classification, allowing for the identification of key themes and sentiments expressed by immigrant users. The study demonstrates the potential of this approach in gaining a deeper understanding of immigrant perspectives within the context of peer-to-peer accommodation, and its implications for social media monitoring and customer satisfaction management.This present study has conducted a critical analysis utilizing efficient feature extraction techniques, including N-grams and TF-IDF, to optimize identifying positive, neutral, and negative feedback. Furthermore, five different models were utilized, and the training and testing processes were accompanied by parameter tuning. Ultimately, the study concluded that the Random Forest (RF) classifier performed exceptionally well, achieving a 95% accuracy rate
