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
Integrated navigation systems
No full textS ciljem povećanja sigurnosti plovidbe i smanjivanja radnog opterećenja časnika na straži pojavila se potreba za povezivanjem brodskih navigacijskih instrumenata, uređaja i sustava u jedan integrirani navigacijski sustav. Ovisno o broju povezanih uređaja i sustava te o njihovoj namjeni postoje različite izvedbe navigacijskih integriranih sustava, a osnovna svrha svakog integriranog navigacijskog sustava je prikaz svih bitnih podataka i funkcija za vođenje navigacije na radnoj stanici. Integrirani navigacijski sustavi moraju omogućiti navigacijske zadatke planiranja rute, nadzora rute, izbjegavanja sudara, prikaza podataka o navigacijskom statusu broda te upravljanje navigacijskim podatcima i uzbunom. Kako bi se povećala učinkovitost integriranih navigacijskih sustava međusobno se povezuju gotovo svi brodski navigacijski uređaji i sustavi poput radara, autopilota, GPS-a, ECDIS-a, AIS-a, VDR-a, kompasa, brzinomjera te meteoroloških instrumenata. U prvom dijelu rada opisuju se zahtjevi, obvezne i dodatne funkcije integriranih navigacijskih sustava, a u drugom dijelu uređaji i sustavi koji se mogu povezivati u sklopu integriranih navigacijskih sustava.To improve safety of navigation and to reduce workload of navigating officers there was a need for connecting ship's navigating instruments, devices and systems into one integrated navigation system. Depending on number and function of connected devices and systems, various designs of integrated navigation systems exist. The main purpose of every integrated navigation system is display of relevant navigation data and functions on a work station. Integrated navigation systems have to provide the following navigational tasks: route planning, route monitoring, collision avoidance, display of navigational status, control of navigational data and alarm management. To increase efficiency of integrated navigation systems, almost all ship's devices and systems such as radar, autopilot, GPS, ECDIS, AIS, VDR, compasses, speed logs and meteorological instruments are interconnected. Requirements, mandatory and additional functions of integrated navigation systems are described in the first part of this paper, while the second part includes description of devices and systems which are interconnected into integrated navigation systems
Cardiorenal effects of new antidiabetic drugs
No full textŠećerna bolest je složen poremećaj metabolizma ugljikohidrata, proteina i lipida čija je temeljna karakteristika kronično povišena razina glukoze u krvi. Koliki je ta bolest teret za hrvatsko zdravstvo dovoljno govori podatak da je u Republici Hrvatskoj u 2022. godini, prema podacima CroDiab Registra, bilo 388.213 osoba sa šećernom bolešću. Patofiziološki, šećerna bolest nastaje kao posljedica smanjene sekrecije inzulina iz beta stanica gušterače ili zbog periferne inzulinske rezistencije. Postoje četiri osnovna oblika šećerne bolesti, a to su šećerna bolest tip 1 i tip 2, gestacijska šećerna bolest i specifični tipovi šećerne bolesti zbog drugih uzroka. Navedeni oblici šećerne bolesti prezentiraju se različitim kliničkim slikama. Liječenje šećerne bolesti provodi se regulacijom prehrane, povećanjem tjelesne aktivnosti te farmakoterapijom. Komplikacije šećerne bolesti dijele se na akutne i kronične. Kronične komplikacije rezultat su promjena na malim i velikim krvnim žilama te imaju velik utjecaj na kardiovaskularni sustav i bubrege. Kardiovaskularne komplikacije vodeći su uzrok smrti u populaciji dijabetičara, dok je dijabetička nefropatija vodeći uzrok kronične bubrežne bolesti općenito. Stoga je važno u terapijskom pristupu pacijentima s dijabetesom, osim adekvatne regulacije glikemije, smanjiti vjerojatnost nastanka neželjenih kardiovaskularnih događaja i kronične bubrežne bolesti. Navedena stanja mogu se spriječiti ili njihov razvoj usporiti primjenom kardioprotektivnih i nefroprotektivnih lijekova kao što su novi antidijabetici, preciznije agonisti GLP-1 receptora i SGLT-2 inhibitori. Brojne randomizirane kliničke studije pokazale su povoljne kardiorenalne učinke novih antidijabetika, ali i druge benefite kao što su smanjenje tjelesne mase, povoljan utjecaj na regulaciju lipida te protuupalni učinke.Diabetes mellitus is a complex disorder of the metabolism of carbohydrates, fats and proteins. Its main characteristic is chronic hyperglycemia resulting from defects in insulin secretion from beta cells of the pancreas or peripheral insulin resistance. Diabetes mellitus represents a great burden to the Croatian healthcare system. In 2022, there were 388.213 people registered in Croatia as diabetics by the CroDiab register. There are four main types of diabetes: type 1 diabetes mellitus, type 2 diabetes mellitus, gestational diabetes and other specific types of diabetes. Different types of diabetes also have different clinical presentations. The main therapeutic approaches include diet, increased physical activity and pharmacotherapy. Complications of diabetes mellitus are divided into two main groups: acute and chronic. Chronic complications result mainly from changes in small and large blood vessels. Moreover, chronic complications have a great impact on the cardiovascular and renal systems. Cardiovascular complications are the leading cause of death in the population of diabetics, while diabetic nephropathy represents the leading cause of chronic kidney disease generally. Consequently, in addition to glycemic control, it is crucial to minimize the probability of cardiovascular events and chronic kidney disease during treatment. New antidiabetic drugs, like GLP-1 receptor agonists or SGLT-2 inhibitors, are cardioprotective and nephroprotective and can prevent the onset or slow down the progression of cardiovascular complications and chronic kidney disease. Numerous randomized clinical trials have shown caridiorenal benefits of new antidiabetic drugs. Also, there are other benefits of new antidiabetic drugs, like weight reduction, blood lipid management and anti-inflammatory effects

Robotic process automation
No full textRobotska automatizacija procesa je unaprijed konfigurirana instanca softvera koja koristi poslovna pravila i predefinirane aktivnosti kako bi autonomno izvršila kombinaciju procesa, aktivnosti, transakcija i/ili zadataka u jednom ili više nepovezanih softverskih sustava. Spomenute instance softvera nazivaju se softverskim robotima ili, kraće, botovima. Roboti izvode svoj rad na prezentacijskom sloju odnosno konfigurirani su da oponašaju akcije radnika kretanjem kroz korisnička sučelja digitalnih sustava zbog čega ne zahtijevaju nikakve izmjene postojećih sustava. Ova tehnologija obećava brojne prednosti, od smanjenja troškova, preciznijeg i bržeg izvođenja nekog rada do većeg zadovoljstva radnika kojima roboti pomažu u izvođenju radnih zadataka. U prvom dijelu, rad istražuje razvoj ove tehnologije, njezine prednosti i nedostatke, razlike naspram tradicionalnih pristupa automatizaciji procesa te uloge i faze izvođenja projekata robotske automatizacije procesa. U drugom dijelu rada, kao odgovor na skupe komercijalne odnosno vlasničke alate koji se koriste za robotsku automatizaciju procesa, na praktičnom primjeru predstavljena je upotreba postojećih tehnologija otvorenog koda poput programskog jezika Python, Robot i RPA Frameworka te alata za automatizaciju Jenkins u svrhu razvoja programskog koda robota te upravljanja radom istih

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
