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

Paradoxi morbi? Historical reflections on the Syphillis Epidemic in Early Modern Europe
No full textOvaj rad iz historiografskog pogleda razmatra porijeklo epidemije sifilisa koja se prema današnjem znanstvenom mišljenju datira u razdoblje ranog novog vijeka kada se čovjek suočavao s brojnim političkim, društvenim, ekonomskim i kulturnim promjenama koje su uvelike bile uvjetovane mikroorganizmima, otrovnim patogenima koji su pronašli način kako mutirati i oslabiti svog domaćina. Interdisciplinarnom metodologijom je pružena šira slika veneričke bolesti, pri čemu se pokušalo odgovoriti na pitanje je li sifilis doista posljedica Kolumbovih putovanja ili je kao spolna infekcija bio prisutan i ranije, ali manje virulentan nego u ranom novom vijeku. Rad je strukturiran u četiri poglavlja koja su fokusirana na patologiju sifilisa, renesansne liječnike koji su pokušavali pronaći adekvatna rješenja za sprečavanje širenja bolesti, društvenu perspektivu epidemije i, u konačnici, na primjeru engleskih vladara Henrika VIII. i Marije Tudor, mogućnost neurosifilisa kao uzroka određenih političkih i društvenih odluka.This paper deals with the origins of the syphilis epidemic from a historiographical perspective, considering current scientific opinion which dates it to the early modern age. During this time, humanity faced numerous political, social, economic, and cultural changes that were largely influenced by microorganisms—poisonous pathogens that had found ways to mutate and weaken their host. Using an interdisciplinary methodology, this paper aims to provide a broader understanding of venereal disease, addressing whether syphilis was indeed a result of Columbus's voyages or if it was present earlier as a sexually transmitted infection, albeit less virulent than in the early modern period. The paper is structured into four chapters focused on the pathology of syphilis, Renaissance doctors who sought adequate solutions to prevent the spread of the disease, the social perspective of the epidemic, and finally, using English rulers Henry VIII and Mary Tudor as examples, the possibility of neurosyphilis as a factor in certain political and social decisions

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
The position of Jews and Muslims in the light of the Spanish Inquisition
No full textŠpanjolska je inkvizicija obilježila povijest ranog novog vijeka na Pirenejskom poluotoku. Zahvaljujući buli pape Siksta IV., španjolski je kraljevski par Ferdinand Aragonski i Izabela Kastilijska koristio Inkviziciju kao oružje u stvaranju što centraliziranije države sa čistim nacionalnim identitetom. Znatnu ulogu u svemu tome je imala i aristokracija koja je vidjela prijetnju u „novokršćanima“ i njihovoj važnosti na raznim poljima društvenog života. Nakon protjerivanja conversosa i moriscosa iz Monarhije, pojavljuju se negativne posljedice koje su usporile daljni razvoj samog Kraljevstva. Prisilnim odlaskom “novokršćana“ Kraljevstvo slabi, ne samo na kulturnom, već i gospodarskom i ekonomskom pogledu. U konačnici, inkvizicija nije uspjela ostvariti glavni cilj na Pirinejskom poluotoku, a to je bilo moguće stvaranje duhovnog i nacionalnog jedinstva kojem je se nadao katolički kraljevski par.The Spanish Inquisition marked the history of the early modern age on the Iberian Peninsula. With the help of the bull of Pope Sixtus IV, the Spanish royal couple Ferdinand of Aragon and Isabella of Castile used the Inquisition as a weapon for creating a centralized state with a pure national identity. The aristocracy also played a significant role in the process, seeing a threat in the "new Christians" and their importance in various fields of social life. After the expulsion of conversos and moriscos from the Monarchy, new negative consequences slowed down further development of the Kingdom itself. With the forced departure of the "new Christians," the Kingdom weakens, not only culturally, but also economically. Ultimately, the Inquisition failed to achieve the main goal on the Iberian Peninsula, and it was the possibility to create the spiritual and national unity for which the Catholic royal couple had hoped
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
Constant mean curvature surfaces and associated focal curves and surfaces in Minkowski space
Get PDFU radu su proučavane plohe konstantne srednje zakrivljenosti (CMC plohe) i njima pridružene fokalne krivulje, odnosno plohe u Minkowskijevom prostoru. Minkowskijev prostor je specijalan ambijentni prostor u kojemu, s obzirom na definiranu pseudo-metriku, razlikujemo tri vrste vektora, krivulja, odnosno ploha. U prva tri poglavlja (1, 2, 3) opisani su osnovni pojmovi koje koristimo u radnji te su prikazana osnovna svojstva, primjeri i klasifikacija minimalnih, maksimalnih i pravih CMC ploha u Minkowskijevom prostoru. U poglavlju 4 proučavana je -evoluta i njen poseban slučaj, harmonijska evoluta plohe. U prvom dijelu istraživana su svojstva harmonijskih evoluta pravčastih, helikoidalnih i translacijskih ploha. Dobiveni rezultati su analogni rezultatima u euklidskom prostoru. U drugom dijelu proučavana su svojstva harmonijskih evoluta kvazi-umbiličkih ploha. Kod takvih ploha harmonijska evoluta degenerira u krivulju što se ne može dogoditi u euklidskom prostoru. Štoviše, dokazano je da harmonijska evoluta i bazna krivulja B-namotajne plohe konstantne srednje zakrivljenosti () čine svjetlosni Bertrandov par. Nadalje, pokazano je kako od zadane krivulje konstruirati B-namotajnu plohu čija je harmonijska evoluta zadana krivulja. Na kraju poglavlja istraživana su svojstva -evolute, a dobiveni rezultati predstavljaju znatna proširenja rezultata u euklidskom prostoru. U poglavlju 5 proučavane su cikloidne krivulje. Izvedena je njihova parametrizacija i pokazano je da se iste mogu dobiti kao projekcije sfernih općih zavojnica. Konstruirani su novi primjeri maksimalnih ploha pomoću Björlingove formule, tzv. cikloidne maksimalne plohe. Dan je njihov Weierstrassov prikaz i pokazano je da su dobivene plohe algebarske te da dopuštaju racionalnu parametrizaciju.In this doctoral thesis, the surfaces of constant mean curvature (CMC surfaces) and associated focal sets in Minkowski space are studied. Minkowski space is a special ambient space in which, with respect to defined pseudo-metric, we distinguish three types of vectors, curves and surfaces. In the first three chapters of the thesis, we give an overview of basic concepts and theorems in Minkowski space, local theory of curves and surfaces, as well as examples and classification of minimal, maximal and CMC surfaces in Minkowski space. In the chapter 4, the -evolute and its special case, the harmonic evolute of a surface, are analyzed. In the first part, we studied harmonic evolute of ruled, helicoidal and translation surfaces, respectively. Obtained results are analogous to the results in Euclidean case. In the second part, we studied the harmonic evolute of the quasi-umbilic surfaces. Contrary to the results in Euclidean case, the harmonic evolute of such surfaces is a curve. Moreover, it is proved that the harmonic evolute of a B-scroll of constant non-vanishing mean curvature, together with its base curve forms a null Bertrand pair. Furthermore, it is shown how to reconstruct B-scroll from a given harmonic evolute. At the end of the chapter, we studied properties of -evolute and the obtained results present significant extension of the results in Euclidean case. In the chapter 5, the cycloidal curves are considered. Their parametrization is presented, as well as shown that they can be obtained as projections of spherical generalized helices. By using the Björling formula, new examples of maximal surfaces are constructed, so-called cycloidal maximal surfaces. We derived their Weierstrass representations and proved that given surfaces are algebraic surfaces which admit rational parametrization
