    Alpine plant species converge towards adopting elevation-specific resource-acquisition strategy in response to experimental early snow-melting

    <p>An experimental to assess the effect of early snow-melting on alpine species at contrasting elevation was established in 2019 at Rohtang (32°22' N; 77°16' E) in western Himalaya. After completion of 02 year of experiment, sampling was performed on 08 alpine plant species. We have collected leaf functional trait and physiological traits during peak growing season (August 2020) from two elevation (3850 and 4150 m) and from control and treatment plots. The trait values of 15 replicates for each species were given here for leaf functional traits (viz. leaf area, specific leaf area, leaf dry matter content, leaf water content, plant height) and  trait values of 05 replicated for each species were given for elemental (Nitrogen % and carbon/nitrogen ratio ) and physiological traits (leaf chlorophyll content, Carotenoid content, Malondialdehyde equivalents, Phenol content, Proline content, Total soluble Sugar content, Total protein content). We have provided trait values from both control and treatment plots. </p>This research work was funded by Council of Scientific and Industrial Research (CSIR), India (MLP0172, MLP 205) and DST-SERB project CRG/2022/007618

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    Phosphorus Deficiency Phosphorous Deficiency in Animals

    Phosphorus deficiency is a condition, in which Phosphorus is insufficient or is not utilized properly. Phosphorus is a mineral that is vitally important to the normal metabolism of numerous compounds and in solution an acid that, with sulphur, must be neutralized by the base forming ions of sodium, potassium, calcium, and magnesium. About 70 of retained Phosphorus combines with calcium in bone and tooth structure. Phosphorus is the principal element in the structure of the nucleus and cytoplasm of all tissue cells. It is also a universally distributed component of skeletal, nerve, and muscle tissues. A reduced concentration of phosphorus in the blood serum is a disorder known as hypophosphatemia. Phosphorus deficiency may cause bone diseases such as rickets in animals. An improper balance of phosphorus and calcium may cause osteoporosis. Dietary sources of Phosphorus include milk products, egg yolk, legumes, nuts, andwhole grains.

    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 link
    We 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 link
    We 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
