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
Development of Computer Network Packet Simulator
Get PDFZavršni rad zamišljen je i izrađen u dva povezana dijela. Jedan dio je tekstualni koji osim što izlaže znanja iz područja računalnih mreža, služi i kao dokumentacija drugom dijelu rada, razvijenom simulatoru za prijenos paketa računalne mreže. Ta dva dijela zajedno tvore cjeloviti završni rad. Simulator je baziran na TCP/IP modelu mreže, koji je oslonac rada najveće svjetske mreže, Interneta. Rasprostranjenost Interneta i njegovo svakodnevno korištenje od strane više milijardi korisnika, razlog su odabiru ove teme i stvaranju simulatora koji ima za cilj prosječnom korisniku približiti način rada računalnih mreža s razine paketa, odnosno podatkovnih jedinica koje je prenose mrežom. Simulator je zamišljen kao programski alat kojeg je moguće koristiti pri edukaciji različitih skupina korisnika. Kao programski jezik, za razvoj simulatora, odabran je C# zbog jednostavnosti rada s grafičkim elementima i velike popularnosti i zastupljenosti na tržištu.This thesis is designed in two parts. One of them is the text document that conveys knowledge from the field of computer networking, and in the same time serves as a documentation for the other part of this thesis, the developed computer network packet transmission simulator. These two integral parts create a complete bachelor thesis. The simulator is based on TCP/IP network model, which is the backbone of the world's biggest network, the Internet. The sheer reach of the Internet, and it's daily use from billions of users were the main motive for choosing this perticular theme, and the creation of this simulator that has, as it's main goal, the purpose of acquainting an average user to the way computer networks function from the perspective of a packet, or a data unit that is sent through the network. The simulator is designed as a software that can be used as an educational tool for teaching a variety of different users (regarding their previous knowledge). The programing language chosen and used for the development of the simulator is C#. It is used besause of it's simplicity while working with graphical elements, and because of it's popularity and it's market presence
Comparative analysis of different implementations of 5G network architecture
No full textRad se bavi objašnjenjem ključnih tehnologija koje čine osnovu modernih
telekomunikacijskih mreža. Analizira se međuovisnost između 4G i 5G mreža kao i
potreba za IMS sustavom koji se proteže kroz više generacija mobilnih tehnologija. U
radu su detaljno objašnjeni pojmovi kao što su 4G mreže, IMS, virtualizacija te 5G
mreže, a fokus je stavljen na njihov međusobni odnos i funkcionalnosti u kontekstu
implementacije 5G tehnologije.
Poseban naglasak stavljen je na interoperabilnost između 4G i 5G mreža, kako
bi se omogućila nesmetana tranzicija korisnika i usluga iz starijih u novije mreže, te
kako bi se omogućilo istovremeno funkcioniranje obje mreže u prijelaznom razdoblju.
Zaključuje se da će 5G mreža, uz podršku IMS-a i virtualizacije, donijeti poboljšanja u
brzini, vremenu kašnjenja i kapacitetu mreže, omogućujući tako nove usluge i
aplikacije koje su ključne za razvoj industrije i društva.The paper focuses on explaining the key technologies that form the foundation
of modern telecommunication networks. It analyzes the interdependence between 4G
and 5G networks as well as the need for the IMS system, which spans multiple
generations of mobile technologies. The paper provides a detailed explanation of
concepts such as 4G networks, IMS, virtualization, and 5G networks, with an
emphasis on their interrelation and functionalities in the context of 5G technology
implementation.
Special emphasis is placed on the interoperability between 4G and 5G networks
to ensure seamless transitions for users and services from older to newer networks,
as well as to enable the simultaneous operation of both networks during the transition
period. It concludes that the 5G network, supported by IMS and virtualization, will bring
improvements in speed, latency, and network capacity, thus enabling new services
and applications that are crucial for the development of industry and society
