Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
The role of sharing economy in changing consumer transport behavior
No full textEkonomija dijeljenja je vrlo inovativan poslovni model čija je usmjerenost postavljena prema ostvarenju mogućnosti zajedničke potrošnje za određeno dobro na temelju digitalnih platformi. Naglašava se kako su suvremene tehnologije te koje su omogućile kreaciju novih poslovnih modela. Ekonomija dijeljenja stoga se postavlja u usku vezu s konceptom kolaborativne potrošnje, tj. potrošnjom kojom je omogućeno korištenje roba te usluga putem dijeljenja. U segmentu transporta koriste se upravo usluge dijeljenja koje su na prostorima Republike Hrvatske najpoznatije pod nazivom Uber i Bolt. Putem istraživanja utvrđena je upoznatost s pojmom ekonomije dijeljenja, kao i korištenjem usluga dijeljenja. Ono što se konkretno smatra najvažnijim je zapravo ekonomičnost, brzina usluge te dostupnost. Svrha ovog rada je ukazati na važnost ekonomije dijeljenja u životu današnjeg čovjeka te njegovom transportnom ponašanju. Cilj rada usmjeren je na istraživanje uporabe ekonomije dijeljenja na području Republike Hrvatske.The sharing economy is a very innovative business model whose focus is set on realizing the possibility of shared consumption for a particular good based on digital platforms. It is emphasized that modern technologies have enabled the creation of new business models. The sharing economy is therefore closely linked to the concept of collaborative consumption, ie consumption that enables the use of goods and services through sharing. In the transport segment, sharing services are used, which are best known in the Republic of Croatia as Uber and Bolt. Through research, the familiarity with the concept of sharing economy was established, as well as the use of sharing services. What is specifically considered most important is actually economy, speed of service and availability. The purpose of this paper is to point out the importance of the sharing economy in the life of today's man and his transport behavior. The aim of this paper is to investigate the use of the sharing economy in the Republic of Croatia
The Vulnerability of Banat Bulgarian in Serbia. An Overview
No full textThis chapter investigates the vulnerability of Banat Bulgarian in Serbia through a questionnaire completed by members of the Banat Bulgarian community in the villages of Ivanovo, Skorenovac, Belo Blato and Konak. The results indicate that 43.4% of the participants’ children speak Banat Bulgarian fluently, a significant decline from the percentage of the respondents’ parents, who used the variety exclusively or mostly, and the respondents who use Banat Bulgarian along with Serbian and another language. Banat Bulgarian is mainly used within the family and less frequently with friends, almost never with neighbours, colleagues, clergy, and officials. Serbian dominates in private and social discussions. The dominance of Serbian is also reflected in the respondents’ self assessment of their language skills: Serbian received ratings of good, very good, and excellent, whereas Banat Bulgarian was often rated as poor or non-existent. Despite this, the majority of respondents considered Banat Bulgarian important and said it symbolises their community and culture. Banat Bulgarian is absent from the school system and official institutions in Serbia; it is only present in the linguistic landscape of the village of Ivanovo on official signs and minimally represented in cultural life, radio and TV broadcasts, websites, and social media. Nevertheless, only a few respondents consume such content in their language. Research shows that Banat Bulgarian is endangered in all examined domains. The dominance of Serbian, particularly apparent in language proficiency assessment and poor transmission of Banat Bulgarian to younger generations, and the almost complete absence of Banat Bulgarian in institutional and cultural fields suggest that the latter is a language used exclusively at home

Clinical and Demographic Characteristics and Fracture Risk in Patients Directed to Densitometry
No full textCilj: Svrha je ovog istraživanja bila ispitati kliničko-demografske karakteristike žena koje dolaze na denzitometrijsko mjerenje u KBC Split te procijeniti njihov rizik za prijelome.
Ispitanici i postupci: Ovo je istraživanje provedeno u Regionalnom centru za dijabetes, endokrinologiju i bolesti metabolizma Kliničkog bolničkog centra Split. U istraživanju je sudjelovalo 30 postmenopauzalnih žena s osteoporozom, 30 s osteopenijom i 30 kontrolnih ispitanica. Za prikupljanje podataka o ispitanicama korištena je medicinska dokumentacija, nalaz denzitometrijskih parametara i rizik za prijelome izračunat putem FRAX® (engl. Fracture Risk Assessment Tool) aplikacije. Ispitanice su podijeljene u tri skupine, ovisno o nalazu T vrijednosti, odnosno koštane mineralne gustoće.
Rezultati: Statistički je značajna razlika postojala pri usporedbi pojavnosti patoloških prijeloma među skupinama (10 ispitanica u skupini s osteoporozom (33,3%), 5 u skupini s osteopenijom (16,7%) i 3 (10%) u kontrolnoj skupini; P=0,024). Nadalje, najveći je broj ispitanica na denzitometrijsko mjerenje upućen od strane liječnika obiteljske medicine (N=31; 34,4%) i specijalista onkologa (N=12; 13,3%). Statistički značajna razlika nije pronađena pri usporedbi indeksa trabekularne kosti među skupinama (1,25 ± 0,07 vs. 1,28 ± 0,09 vs. 1,29 ± 0,13; P=0,250). Prema rezultatima FRAX®-a bez uključenja BMD-a, skupina s osteoporozom imala je najveći rizik za ozbiljan prijelom u odnosu na ostale skupine (8,0 (6,4-14,0) vs. 7,1 (4,9-12,0) vs. 6,1 (4,5-7,6) %; P=0,013). Uključenjem koštane mineralne gustoće (BMD) u izračun, a potom i indeksa trabekularne kosti (TBS), ispitanice s osteoporozom imale su statistički značajno veći rizik za veliki prijelom u odnosu na skupinu s osteopenijom i kontrolnu skupinu u oba navedena slučaja (P<0,001). U ukupnoj ispitivanoj populaciji, FRAX® izračunom desetogodišnja je vjerojatnost ozbiljnog prijeloma iznosila 6,8 (5,0-11,0) %, dodatkom BMD a u izračun 5,7 (4,1-10,0) %, a dodatkom BMD-a i TBS-a 6,6 (4,8-11,0) % (P<0,001). Nadalje, u skupini ispitanica s niskom vjerojatnosti prijeloma (N=62) rizik za prijelom iznosio je 5,9 (4,6-6,9) %, s prilagodbom za BMD 4,9 (3,7-6,2) %, a s prilagodbom za BMD i TBS 5,6 (4,3-6,7) % (P<0,001). U skupini s umjerenom vjerojatnosti za prijelom (N=21) rizik za prijelom iznosio je 13,0 (11,0-16,0) %, s prilagodbom za BMD 10,0 (8,8-14,0) %, a s prilagodbom za BMD i TBS 11,0 (9,2-14,0) % (P<0,001).
Zaključak: Ovo je istraživanje pokazalo da je rizik za prijelome veći u bolesnica s osteoporozom i osteopenijom u odnosu na zdrave postmenopauzalne žene. Također, rizik za prijelome pokazao je najviše vrijednosti u izračunu bez prilagodbe za BMD i TBS u ukupnoj ispitivanoj populaciji.Objectives: The aim of this study was to examine the clinical and demographic characteristics of women who come for densitometric measurement at the University Hospital of Split and to assess their risk for fractures.
Subjects and Methods: This study was conducted at the Regional Center for Diabetes, Endocrinology and Metabolic Diseases of the University Hospital of Split. The study included 30 postmenopausal women with osteoporosis, 30 with osteopenia, and 30 control subjects. Medical documentation, densitometric parameters and fracture risk calculated using the FRAX® tool were used to collect data on the subjects. Subjects were divided into three groups, depending on their T score, ie bone mineral density.
Results: There was a significant difference when comparing the incidence of pathological fractures between groups (10 subjects in the group with osteoporosis (33.3%), 5 in the group with osteopenia (16.7%) and 3 (10%) in the control group; P = 0.024). Furthermore, the largest number of respondents were referred to densitometric measurements by general practitioners (N=31; 34.4%) and oncologists (N=12; 13.3%). No statistically significant difference was found when comparing the trabecular bone score between the groups (1.25±0.07 vs. 1.28±0.09 vs. 1.29±0.13; P=0.250). According to the results of FRAX® without the inclusion of BMD, the group with osteoporosis had the highest risk of serious fracture compared to other groups (8.0 (6.4-14.0) vs. 7.1 (4.9-12.0) vs. 6.1 (4.5-7.6) %; P=0.013). By including BMD in the calculation and TBS afterwards, subjects with osteoporosis had a statistically significantly higher risk of major fracture compared to the osteopenia group and the control group in both cases (P<0.001). In the total study population, the ten-year probability of a serious fracture calculated by FRAX® was 6.8 (5.0-11.0) %, by adding BMD to the calculation 5.7 (4.1-10.0) %, and by adding BMD and TBS 6.6 (4.8-11.0) % (P<0.001). Moreover, in the group of subjects with low fracture probability (N=62), the fracture risk was 5.9 (4.6-6.9) %, by adding BMD 4.9 (3.7-6.2) %, and by adding BMD and TBS 5.6 (4.3-6.7) % (P<0.001). In the group with moderate fracture probability (N=21) the fracture risk was 13.0 (11.0-16.0) %, by adding BMD 10.0 (8.8-14.0) %, and by adding BMD and TBS 11.0 (9.2-14.0) % (P <0.001).
Conclusions: This study has shown that the fracture risk is higher in patients with osteoporosis and osteopenia compared to healthy postmenopausal women. Also, the fracture risk was the highest in the calculation without adjustment for BMD and TBS in the total population study

Temeljni raziskovalni problem predstavlja vprašanje, kako so v plesnih TikTok videoposnetkih predstavljene podobe turističnih destinacij in kako jih uporabniki TikToka dojemajo. TikTok plesne videoposnetke obravnavamo kot marketinško orodje za grajenje pozitivne podobe turistične destinacije. Rezultati koristijo strokovnjakom za marketing ter oddelkom, zadolženim za strateški razvoj turističnih destinacij. Rezultati kvantitativne analize 143 TikTok plesnih videoposnetkov mikro, makro in mega vplivnežev pokažejo prepletanje prikazovanja turističnih znamenitosti, glasbe in plesa. Analiza odzivov uporabnikov TikToka s pomočjo dveh fokusnih skupin in uporabo metode video elicitacije pokaže, dale preplet vseh treh elementov omogoča prepoznavnost turističnih destinacij, kar se kaže kot najboljša strategija za ustvarjanje TikTok plesnih videoposnetkov, namenjenih sooblikovanju pozitivne podobe turistične destinacije.The work provides an overview of the connections between influencer marketing, the image of tourist destinations, and TikTok dance videos. The main research problem revolves around the question of how tourist destinations are represented in TikTok dance videos and how TikTok users perceive them. We view TikTok dance videos as a marketing tool for building a positive image of tourist destinations. The results benefit marketing professionals and departments responsible for the strategic development of tourist destinations. The quantitative analysis of 143 TikTok dance videos from micro, macro, and mega influencers shows the interconnection of showcasing tourist attractions, music, and dance. The analysis of TikTok user responses through two focus groups, combined with the use of the video elicitation method, indicates that the recognition of tourist destinations is enabled by the blending of all these elements, which is demonstrated as the best strategy for creating TikTok dance videos aimed at shaping a positive image of tourist destinations
