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
MANAGERIAL CHALLENGES IN SPORTS ASSOCIATIONS : Final paper
No full textMenadžeri se u svom radu susreću sa mnoštvom izazova. Važnost se menadžera najbolje vidi
u velikim i složenim organizacijama u kojima menadžeri čine mali dio svih zaposlenika.
Međutim, menadžment je veoma važan i za poslovanje bilo kojeg tipa organizacije (od malih
do velikih poduzeća ili udruga) u bilo kojem kontekstu poslovanja (od profitnog do
neprofitnog). U današnje se vrijeme odgovornost za rezultate očekuje od svih zaposlenih te je
stoga granica između menadžera i nemenadžera vrlo fluidna i nejasna. S aspekta menadžmenta
kao teorijskog okvira važno je koliko su menadžeri efikasni i efektivni u obavljanju svog posla.
Relativno je neistraženo kako opća menadžment teorija funkcionira u neprofitnom sektoru
općenito ili u kontekstu upravljanja sportskim udrugama i amaterskim sportskim klubovima.
Cilj je ovog završnog rada kritički analizirati ulogu i specifičnosti ključnih menadžerskih
funkcija u segmentu sportskih udruga. Predmet istraživanja u ovom završnom radu je amaterski
košarkaški klub Vinkovci koji je bio polazište za promišljanje i uopćavanje menadžerskih
izazova karakterističnih za ovaj oblik organizacija. Na temelju informacija prikupljenih
intervjuiranjem predsjednika i dopredsjednika košarkaškog kluba Vinkovci protumačene su
temeljne zadaće, upravljačka i organizacijska shema amaterskog sporta. Kvalitativnom
analizom prikupljenih podataka ukazano je kako se raznim menadžerskim pitanjima i vođenjem
kluba bave osobe čije primarno zanimanje nije iz područja menadžmenta a često niti iz područja
ekonomije te kako je dominantni menadžerski izazov u kontekstu amaterskog sporta privlačenje
talentiranih trenera i igrača, osiguranje njihove motivacije kao i privlačenje i zadržavanje
kvalitetnih sponzora i ostalih dionika kako bi se osiguralo stabilno financiranje sportskih
klubova.Managers face many challenges in their work. The importance of managers is best seen in large
and complex organizations, in which managers make up a small proportion of all employees.
However, management is also essential for the business of any type of organization (from small
to large companies or associations) in any business context (from for-profit to non-profit). At
the same time, nowadays, responsibility for results is expected from all employees, and
therefore the boundary between managers and non-managers is very fluid and unclear. From
the aspect of management as a theoretical framework, it is essential how efficient and effective
managers are in doing their job. However, it is relatively unexplored how general management
theory works in the non-profit sector in public or in the context of managing sports associations
and amateur sports clubs. This final paper aims to critically analyze the role and specifics of
essential managerial functions in the segment of sports associations. The research subject in
this final paper is the amateur basketball club Vinkovci, which was the starting point for
reflection and generalization of managerial challenges characteristic of this form of
organization. Based on the information gathered by interviewing the president and vice
president of the Vinkovci basketball club, the basic tasks, management and organizational
scheme of amateur sports were interpreted. Qualitative analysis of the collected data indicates
that various management issues and club management are dealt with by persons whose primary
occupation is not in the field of management or even economics, and that the dominant
managerial challenge in the context of amateur sports is attracting talented coaches and players
and retaining quality sponsors and other stakeholders to ensure stable funding for sports clubs
GENETIC ANALYSIS IN PEDIATRIC INTESIVE CARE AT KBC RIJEKA - RETROSPECTIVE ANALYSIS
No full textRazvojem medicinske genetike i sve većom implementacijom genetskog testiranja došlo je do njezine integracije u gotovo sve dijelove medicine. Cilj ovog retrospektivnog istraživanja bio je prikaz otkrivenih genetskih poremećaja, te koje su se metode koristile za otkrivanje istih. Ovim istraživanjem obuhvaćena su sva djeca koja su liječena u JILu Klinike za pedijatriju, KBC-a Rijeka u je vremenskom razdoblju od 01. siječnja 2018. godine do 31. prosinca 2023. godine. Analizirani su slijedeći podatci: dob, spol, razlog upućivanja na genetsku analizu, rezultate genetske analize te korištene metode. Od 2018. do 2023. godine u istraživanju je sudjelovalo ukupno 28 ispitanika. Od ukupnog broja ispitanika 13 je muškog (46%), a 15 ženskog spola (54%). Najzastupljeniju dobnu skupinu čine djeca mlađa od godine dana života (68%). Najčešća indikacija za testiranje je kardiološka bolesti (29%). Kod najvećeg broja ispitanika (68%) korištena je NGS metoda. Pozitivni rezultati testiranja dobiveni su u 46% slučajeva. Dobiveni rezultati ukazuju na porast broja provedenih genetskih testiranja u razdoblju od 2018. do 2023. za 100% što ukazuje na povećanje dostupnosti genetičkog testiranja kao i povećanje njegove primjene u kliničkoj praksi.The development od medical genetics and its increasing implementation of genetic testing led to its integration into almost all areas of medicine. The aim of this retrospective study was to present the detected genetic disorders and which method were used to detect them. This research covers the period from January 1, 2018 to December 31, 2023 and includes the following data: age, gender, primary group of diseases, results and methods used for genetic analysis. From 2018. to 2023. a total of 28 patients participated in the study, 13 were male (46 %) and 15 were female (54%). The most common age group was patients under the age of one (68%). The most common indications for genetic testing were cardiac diseases (29%) . The most commonly used genetic method was NGS (68%). Positive results were obtained in 46% of cases.Given results indicate a 100% increase in the number of genetics test performed in the period from 2018 to 2023, which shows an increase in the availability of genetic testing as well as an increase in its application in clinical practice
Importance of vitamin d for health
Get PDFD vitamin je vitamin topljiv u mastima koji se tradicionalno povezuje sa zdravljem kostiju. Međutim, novija istraživanja su pokazala da sudjeluje u brojnim reakcijama u ljudskom tijelu, kao i u regulaciji oko 3% ljudskog genoma. Istodobno postoji sve više studija o raširenoj pojavi nedostatka D vitamina diljem svijeta. Ona zabrinjava u svjetlu novih spoznaja o važnoj ulozi D vitamina u bolestima kostiju i drugih sustava, kao što su prevencija rahitisa, poremećaji funkcije kostiju i mišića, prevencija autoimunih bolesti, zloćudnih bolesti, kardiovaskularnih bolesti, infekcija, neurofizioloških i reproduktivnih poremećaja.
Cilj ovog rada je objediniti najnovije podatke o dobrobiti unosa D vitamina i posljedicama njegovog nedostatka. Nadalje, iznesene su dvojbe oko optimalnih razina D vitamina u krvi i navedene aktualne smjernice za suplementaciju tog vitamina. Uzevši u obzir visoku prevalenciju nedostatka D vitamina diljem svijeta, te malu opasnost od trovanja njime, čini se da je danas puno realnija šteta od manjka nego od viška D vitamina.Vitamin D is a fat soluble vitamin involved in numerous reactions in human body. Traditionally, it has been linked to bone health, but we are nowdays aware of its numerous extraskeletal effects and the fact that it regulates about 3% of human genome. Recent reports suggest not only a higher recognition of vitamin D deficiency worldwide, but also various health benefits from vitamin D supplementation. Vitamin D plays an important role in skeletal and extra-skeletal disease areas, such as bone and muscular disfunction, well-known prevention of rickets, prevention of autoimmune diseases, malignancy, cardiovascular diseases, infections, neurophysiological disorders and reproductive disorders.
The aim of this paper is to summarize the latest data on benefits of vitamin D intake and consequences of its deficiency. In addition, doubts on optimal vitamin D blood level and recent guidelines for its supplementation are pointed out. Having in mind high prevalency of vitamin D deficiency and its insignificant intoxication risk, nowdays the damage from vitamin D deficit seems to be more realistic than the damage from its excess
