    Vrsta Hermodice carunculata termofilni je grabežljivac koji je posljednjih godina proširio areal rasprostranjenosti u Sredozemnom i Jadranskom moru, gdje se često može susresti u većim skupinama. Zbog toga je cilj ovog diplomskog rada bio prikazati stanje populacije ove vrste na istočnoj strani srednjeg Jadrana te posebno u arhipelagu otoka Brača. U radu su prikazani podaci o prisutnosti H. carunculata na hrvatskoj obali srednjeg Jadrana, te posebno podaci prikupljeni na području otoka Brača, kao i jednog dijela otoka Hvara i Šolte. Analizom podataka prikupljenih na hrvastkoj obali srednjeg Jadrana u 2019. godini, od ukupno 93 lokacije na kojima su prikupljeni podaci, na njih 91 uočeno je prisustvo vrste H. carunculata. Na otoku Braču prisustvo vrste je dominiralo s južne strane otoka, kao što je i slučaj na otoku Šolti, dok su na Hvaru zabilježene tek dvije lokacije sa sjeverne strane otoka. Naknadnim praćenjem promjena u distribuciji navedene vrste u istraživanom području, moglo bi se procijeniti kakav bi utjecaj ova vrsta mogla imati na bentoske zajednice.The species Hermodice carunculata is a thermophilic predator that has expanded its range in recent years in the Mediterranean and in the Adriatic Sea, where it can often be found in larger groups. Therefore, the aim of this thesis was to investigate the state of the population of this species on the eastern side of the Central Adriatic and especially in the waters of the island of Brač. The paper presents data on the presence of H. carunculata on the Croatian coast of the Central Adriatic, and especially data collected on the island of Brač, and in one part of the islands Hvar and Šolta. The analysis of data collected along the Croatian coast in the Central Adriatic in 2019, from 93 locations where data were collected, the presence of H. carunculata was observed in 91 of them. On the island of Brač, the presence of the species dominated on the southern side of the island, as is the case on the island of Šolta, while on Hvar island only two locations were recorded on the northern side of the island. With the subsequent monitoring of changes in distribution of this species the impact of this species on benthic communities in this area could be assessed

    Food additives in marine products

    Prehrambeni aditivi ili dodaci koriste se u proizvodnji hrane kako bi se proizvodima produljio rok trajanja ili poboljšala određena svojstva. Dodaci hrani mogu biti prirodni ili umjetni (sintetizirani). U proizvodima morskog ribarstva dodaci se najčešće koriste za sprječavanje oksidacije lipida koja uvelike utječe na kakvoću tih proizvoda te za kočenje rasta mikroorganizama. Današnji prehrambeni trendovi promiču korištenje prirodnih aditiva u proizvodima, jer umjetni u većim količinama mogu izazvati štetan učinak za ljudsko zdravlje. Od prirodnih aditiva u ribarstvu se najčešće koriste biljke i biljni ekstrakti koji ne samo da svojom aromom doprinose okusu proizvoda već imaju antioksidativni i antimikrobni učinak u proizvodu. Kako bi se osigurala pravilna uporaba aditiva u hrani i spriječile alergijske reakcije kod ljudi, aditivi su kategorizirani i označeni E brojevima te je njihova primjena regulirana kroz zakonske akte. Iz istoga je razloga jako važno da je proizvod dobro i jasno deklariran zbog sigurnosti i zdravlja potrošača.Nutritive supplements are often used in food production in order to prolong shelf life of the product or to enhance some particular product properties. These supplements can be classified in two categories: natural and artificial. Fishing industry usually uses supplements to slow down growth of microorganisms, as well as to prevent oxidation of lipids, which can have a great impact on the quality of the product. Current trends in nutrition are promoting usage of natural supplements, since artificial ones may have a negative impact on human health. The most common natural additives used in fishing industry are various herbs and herbal extracts, which improve the product's aroma and have anti-oxidant and antimicrobial effect. In order to ensure proper usage of supplements in dietary products and to prevent allergic reactions, all supplements must be categorised and marked by a special E number. Furthermore, usage of these supplements is strictly regulated by laws. Hence, it is very important that each product has a valid and accurate product declaration to avoid any negative impact on the end consumers

    Going Beyond Counting First Authors in Author Co-citation Analysis

    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

    Variations on the Author

    “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

    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

    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

    We 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
