Vanitha) (ICAR / NBAIR / THYS /24032023). Paratypes: 8 females and 6 males with same data as holotype except 5 paratype females with mouthcone reaching up to metathoraxic coxa and one paratype female with 4 pairs of mid-dorsal setae on both sides of abdominal segment IX. Holotype and paratypes deposited in the National Insect Museum, National Bureau of Agricultural Insect Resources (ICAR-NBAIR), Bengaluru, India.</p> <p> <b>Etymology:</b> The species name <i>longirostris</i>, meaning “long rostrum’’, is in reference to the unusually long mouth cone of this species.</p> <p> <b>Comments:</b> This species is interesting in having an elongated mouth cone, a character state also known in a few species of the genus <i>Neohydatothrips</i> John, <i>N. abditus</i> (Hartwig), <i>N. barrowi</i> Mound & Tree, <i>N. catenatus</i> (Hood), <i>N. lepidus</i> (Faure), <i>N. mundus</i> (Hartwig), and <i>N. gracilipes</i> (Hood) (Lima & Mound 2016b). Mouth cone of this species extends beyond the mesothoracic coxae (reaching the metathoraxic coxae in many paratypes), probably longer than in any described <i>Hydatothrips</i> species. Only <i>H. longjingensis</i> Mirab-balou <i>et al.</i> and <i>H. ormocarpi</i> (Faure) have long mouth cone, however, it only reaches to the posterior margin of pronotum (Faure 1962; Mirab-balou <i>et al.</i> 2011). Besides, it is separable from the other members of the genus by the following character combinations: ocellar setae III placed outside ocellar triangle; pronotum yellow without a well-defined blotch except for anterior apodeme; fore wing banded, second vein with 2 setae; abdominal sternites II–VI completely covered with discal microtrichia, posterior margin with complete comb of microtrichia interrupted only at setal bases; abdominal sternites III–VII of male with elongate transverse pore plate.</p>Published as part of <i>Rachana, R.

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

Platinum(II)-BODIPY Conjugates for Organelle Targeted Photodynamic Therapy in Red Light
No full textThe serendipitous discovery of Cisplatin (CP, Peyrone's chloride) as an anticancer agent in 1965 by Barnett Rosenberg led to the evolution of other platinum-based anticancer drugs, namely, Carboplatin in 1989 and Oxaliplatin in 2002 [1]. Researchers subsequently have tried to exploit the therapeutic potential of metal complexes for treatment of various diseases. And a chief focus is set to design metal-based therapeutics to circumvent of the drawbacks associated with the conventional platinum-based chemotherapeutic agents. Thus, as an alternative to chemotherapy, Photodynamic Therapy (PDT) has evolved as a new modality where selective killing of cancer cells can be achieved using a red light photosensitiser by generating singlet oxygen. The major challenge is to develop the combined effects of chemotherapeutic potential of platinum and a red light activatable photosensitiser for photodynamic therapeutic effect simultaneously. The fundamental aim of the thesis work is to design organelle targeted photodynamic therapeutic platinum(II) complexes for achieving near infra-red (NIR) light induced cellular apoptosis through singlet oxygen generation in cancer cells. The employment of dyes that have the ability to generate singlet oxygen and fluorescence emission properties concurrently enables to real time tracking of the drug mechanistic action by determining its cellular uptake, localisation inside cells and its drug action. The nuclear DNA being the major target for conventional chemotherapeutic drugs, in recent years researchers have focussed on targeting a specific organelle to increase the efficacy of the anticancer therapeutics [2].
This thesis deals with the design and synthesis of NIR light active platinum(II) complexes as photodynamic therapeutic agents starting with glucose appended platinum(II) BODIPY conjugates, which displayed selective uptake in cancer cells over healthy cells with notable red light induced cytotoxicity by mitochondrial localisation [3]. The morpholine appended dinuclear platinum(II) centred BODIPY complexes were developed for lysosome targeted PDT agent [3]. The morpholine appended mono-styryl BODIPY conjugated platinum(II) complexes were synthesised and studied for the heavy atom effect induced by iodine atoms for lysosome targeted PDT under red light [3]. A platinum(II) complex with two BODIPY units was found to localise in the endoplasmic reticulum of cancer cells and induce ER stress under red light irradiation to cause cytotoxicity. A cisplatin analogue with malonyl chloride derived BODIPY as O,O donor ligand, named as “Maloplatin” was found to display both DNA binding and mitochondria targeted red light induced PDT activity against cancer cells [3].

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
