Status of the seagrass Posidonia oceanica meadows in the marine area of the cape Kamenjak
No full textPosidonia oceanica predstavlja jedno od najvažnijih staništa u Jadranskom moru. Ova morska
cvjetnica je indikator čistoće mora kao i bitno stanište za mnoge vrste koje obitavaju u ovoj
biocenozi. Monitoring livada morske cvjetnice P. oceanica proveden je na području JU
Kamenjak na sedam postaja ronjenjem pomoću autonomne ronilačke opreme. Cilj ovog
diplomskog rada je utvrditi stanje livada morske cvjetnice P. oceanica te usporediti dobivene
podatke sa podatcima iz 2020. godine. Dobiveni podatci poslužit će za daljnji monitoring
istraživanih lokacija. Dugoročni cilj ovog projekta je aktivna zaštita morskih vrsta i staništa
morske cvjetnice P. oceanica te održivo gospodarenje morem. Livade su kategorizirane prema
gustoći izdanaka prema Giraud (1977) te su postaje Polje i Porer kategorizirane kao livade
rijetke gustoće dok su postaje Fenoliga, Školjić, Šekovac, Franina i Debeljak kategorizirane
kao livade vrlo rijetke gustoće. Usporedba istraživanja iz 2023. i 2020. godine pokazuje
degradaciju livada posidonije na svim istraživanim postajama, povećanje biomase epifitskih
alga na listovima posidonije. Na svim postajama utvrđena je plemenita periska Pinna nobilis,
ali nije utvrđena niti jedna živa jedinka. Prema indeksu sličnosti s obzirom na zabilježene vrste
koje obitavaju na livadama te su zabilježene tijekom ovog monitoringa, najveću sličnost od
99,57 % pokazuju postaje Franina i Školjić.Seagrass Posidonia oceanica represents one of the most important habitats in the Adriatic Sea.
This seagrass is an indicator of the cleanliness of the sea as well as an important habitat for
many species that live in the biocenosis of seagrass meadows. Monitoring of seagrass meadows
P. oceanica was carried out around Public Institution Kamenjak at seven stations by using
SCUBA diving equipment. This thesis aims to determine the state of the seagrass meadows P.
oceanica and to compare the obtained data with the data collected from 2020. The obtained data
will be used for further monitoring of these researched locations. The long-term goal of this
project is the active protection of marine species and the habitat of the seagrass P. oceanica,
and sustainable management of the sea. Meadows are categorized according to the density of
shoots according to Giraud (1977), stations Polje and Porer are categorized as meadows of
sparse density, while the stations Fenoliga, Školjić, Šekovac, Franina and Debeljak are
categorized as meadows of very sparse density. A comparison of research from 2023 and 2020
shows the degradation of Posidonia meadows at all research stations and an increase in the
biomass of epiphytic algae on Posidonia leaves. The protected bivalve Pinna nobilis was
observed at all stations, but not a single living individual was identified. According to the Index
of similarity regarding the recorded species that live in the meadows, and were recorded during
this monitoring, the highest similarity of 99.57% is shown in the stations Franina and Školjić
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
