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
DEMAND FORCASTING IN PRACTICE : Graduate paper
No full textPrognoziranje potražnje se može klasificirati kao poslovni proces koji se obavlja u sklopu
aktivnosti upravljanja lancem opskrbe. Iako kompleksan pojam, može se definirati kao proces
koji sagleda raspoložive podatke kako bi oformio prognozu o razini buduće potražnje.
Predviđanja potražnje mogu se podijeliti na dva osnovna pristupa, a to su kvantitativne metode
i kvalitativne metode predviđanja potražnje. Kvalitativne metode prikupljaju stavove i mišljenja
osoba koje posjeduju određeno znanje o promatranom predmetu. Ona se provode uglavnom
putem upitnika i intervjua, na temelju kojih se u konačnici pokušava oformiti zajedničko
mišljenje ispitane mase. Kvantitativne metode primjenjuju matematičke metode pri formiranju
prognoza. One se primjenjuju kada postoji dovoljna razina povijesnih podataka na temelju kojih
se matematički modeli mogu provesti. Najpoznatija metoda kvantitativnog predviđanja
potražnje jest analiza vremenskih serija. Metoda podrazumijeva postojanje povijesnih podataka
koji su se odvili određenim redoslijedom. Tri su osnovne metode analize vremenskih serija a to
si jednostavno eksponencijalno zaglađivanje, Holtov model ili trendom korigirano
eksponencijalno zaglađivanje, te Wintersov model ili Trendom i sezonalnošću korigirano
eksponencijalno zaglađivanje. Modeli analize vremenskih serija u svoje izračune uvrštavaju
konstante zaglađivanja koje predstavljaju brzinu prilagodbe modela na najnovije spoznaje o
promjenama u potražnji. Pošto se potražnja sastoji od tri uočljiva čimbenika, razine, trenda i
sezonskog faktora, uvrštavanje tih varijabli u izračune prognoza dolazi se do relevantnijih
rezultata. Pri izračuna prognoza potražnje za tvrtku Apple Inc. čija potražnja ima izraženu
sezonalnost i blagi trend rasta primijenjene su sve tri navedene metode analize vremenskih
serija, kao i statična metoda koja svoje izračune dobiva kroz desezonaliziranje potražnje. Na
primjeru podataka tvrtke izračunate su navedene metode kao i prikladne metode mjerenja
pogrešaka kako bi se pobliže opisala primjena takvoga pristupa pri prognoziranju potražnje.Demand forecasting can be classified as a business process performed as a part of supply chain
management. Although a complex term, it can be defined as a process that looks at available
data with the aim of forming a forecast for future demand. Demand forecasting can be divided
into two basic approaches, namely quantitative and qualitative demand forecasting methods.
Qualitative methods gather the views and opinions of people who possess certain knowledge
about the observed subject. They are conducted mainly through questionnaires and interviews,
on the basis of which an attempt is made to form a common opinion of the examined mass.
Quantitative methods apply mathematical methods in forming forecasts. They are applied when
there is a sufficient level of historical data on the basis of which the mathematical models can
be calculated. The best known method of quantitative demand prediction is time series analysis.
The method implies the existence of historical data that unfolded in a certain order. There are
three basic methods of time series analysis, namely simple exponential smoothing, Holt model
or trend-corrected exponential smoothing, and Winters model or Trend and seasonality
corrected exponential smoothing. Time series analysis models include smoothing constants in
their calculations, which represent the speed of adjustment of the model to the latest knowledge
about certain changes in demand. Since the demand consists of three observable factors, level,
trend and seasonality, the inclusion of these variables in the forecast calculations yields more
relevant results. When calculating demand forecasts for Apple Inc. whose demand has a
pronounced seasonality and a slight growth trend, all three before mentioned methods of time
series analysis were applied, as well as the static method, which obtains its calculations through
deseasonalization of demand. The methods were calculated with the data obtained from the
above mentioned company, as well as the appropriate error measurement methods in order to
better describe the application of such approaches while forecasting future demand
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
Insurance service as a strategic element of marketing in insurance
No full textU osiguranju, kao i u svakoj drugoj poduzetničkoj grani, marketing igra veliku ulogu kao sredstvo unaprjeđenja poslovnih rezultata pa samim time i uspješnosti poslovanja pojedine tvrtke. Da bi marketing bio što uspješniji, u bilo kojoj grani, on mora biti osmišljen tako da zahvati pažnju, interes, te zadobije povjerenje ciljanih potrošača. Ovaj rad analizira napore uložene od strane ponuditelja usluga, točnije osigurateljnih društava, kojima se želi ostvariti trajno i stabilno pozicioniranje na tržištu, stjecanje povjerenja među korisnicima te što je moguće bolji rezultat poslovanja na ciljanom tržištu. Stvaranjem široke i kvalitetne ponude uz pomoć detaljnog istraživanja segmenata tržišta te detaljnom izradom i provođenjem marketinškog plana cilj je zauzeti najbolju moguću poziciju među konkurentima na tržištu. Rad objašnjava osnovne pojmove i pretpostavke marketinških djelatnosti sa stajališta sudionika na tržištu. Također daje uvid u osnove marketinških djelatnosti te ciljeva čije se poslovanje u toj grani želi ostvariti. Dakle, govori se kako se detaljnim planiranjem, strpljivim istraživanjem tržišta te profesionalnim provođenjem plana nastupa na tržištu može doći do zapaženih tržišnih rezultata. Ključan faktor uspješnosti poslovanja u osigurateljnoj grani jest informiranje i prilagodba krajnjim potrošačima kako bi njihovo iskustvo poslovanja s društvom za osiguranje bilo što pozitivnije. Time se može ostvariti daljnji utjecaj trenutnih korisnika, kroz njihovo pozitivno iskustvo, na buduće potencijalne korisnike u situaciji kad se dođe do odluke o sklapanju novoga ugovora o osiguranju. Ostvarivanjem dobrog dojma kod trenutnih klijenata stječe se imidž o poslovanju koji može biti od velike važnosti pri donošenju odluke o sklapanju ugovora o osiguranju s određenim osigurateljem prema staroj narodnoj izreci “dobar glas daleko se čuje”, što izvrsno objašnjava srž problema na kojemu se ovaj rad bazira
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
