    Raskrižje, kao mjesto spajanja, razdvajanja, križanja i preplitanja prometnih tokova, mora omogućit smisleno i sigurno odvijanje prometa, a predmetno raskrižje ovog diplomskog rada je raskrižje Selske ceste i Horvaćanske ceste u Gradu Zagrebu. Cilj ovog diplomskog rada je istražiti kako različiti pristupi optimizaciji predmetnog raskrižja utječu na odvijanje prometnih tokova. Osim cestovnih prometnih tokova, velik dio prometne potražnje na predmetnom raskrižju čine nemotorizirani sudionici u prometu, a jedan od razloga je postojanost linija javnog gradskog prijevoza u zoni raskrižja. Zbog takve prometne situacije istražit će se mogućnost implementacije rješenja koje ide u korist vozilima javnog gradskog prijevoza. Istraživanje u okviru ovog diplomskog rada obuhvaća detaljnu analizu postojećeg stanja raskrižja te usporedbu izlaznih rezultata predloženih idejnih prometnih rješenja u vidu građevinskih zahvata i davanja prednosti prolaska vozilima javnog gradskog prijevoza pomoću mikrosimulacijskog alata PTV Vissim i modula PTV Epics. Također, kao treći scenarij istražuje se kako određeni postotak autonomnih vozila u prometnom toku utječe na propusnu moć i razinu usluge raskrižja.An intersection, as a place of connecting, separating, crossing and intertwining of traffic flows, must enable meaningful and safe traffic flow, and the subject intersection of this thesis is the intersection of Selska road and Horvaćanska road in the City of Zagreb. The aim of this thesis is to investigate how different approaches to the optimization of the intersection in question affect the development of traffic flows. In addition to road traffic flows, a large part of the traffic demand at the intersection is made up of non-motorized road users, and one of the reasons is the persistence of public transport lines in the intersection area. Due to such a traffic situation, the possibility of implementing a solution that benefits public transport vehicles will be explored. The research within this thesis includes a detailed analysis of the existing state of the intersection and a comparison of the output results of the proposed conceptual traffic solutions in the form of construction interventions and giving priority to the passage of public transport vehicles using the PTV Vissim microsimulation tool and the PTV Epics module. Also, as a third scenario, it is investigated how a certain percentage of autonomous vehicles in the traffic flow affects the throughput and service level of the intersection

    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

    Promet je jedna od osnovnih djelatnosti ljudskog društva čiji je osnovni cilj osigurati efikasno i sigurno kretanje transportnih entiteta. Na temelju prikupljenih podataka vezanih za Varaždinsku županiju analizirana je cestovna mreža županije. Opisan je geoprometni položaj županije i njezin značaj u povezivanju Republike Hrvatske s europskim prometnim sustavom. Analizom prostorno – planske dokumentacije prikazana je razvijenost trenutnog stanja prometnog sustava. Na temelju podataka o brojanju prometa koje objavljuju „Hrvatske ceste d.o.o.“, dobiven je uvid u trend kretanja prometne potražnje na javnim cestama županije. Navedeni su određeni nedostaci na cestovno mreži županije na temelju kojih su dani prijedlozi poboljšanja cjelokupne cestovne mreže Varaždinske županije.Transport is one of the basic activities of human society whose main goal is to ensure efficient and safe movement of transport entities. Based on the collected data related to Varaždin County, the road network of the county was analyzed. The geo-traffic position of the county and its importance in connecting the Croatia with the European transport system are described. The analysis of planning documentation shows the development of the current state of the transport system. Based on the data on traffic counting published by "Hrvatske ceste d.o.o.", it was obtained in the trend of traffic demand on public roads of the county. Certain disadvantages on the road network of the county are listed, on the basis of which suggestions were made for the improvement of the entire road network of Varaždin County

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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
