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
Senā mikrobioma biomolekulārais raksturojums arheoloģiskajos paraugos Latvijā
Get PDFSenā cilvēka mikrobioma izpētes joma pēdējo gadu laikā ir strauji attīstījusies. Mūsdienu sekvencēšanas tehnoloģijas ļauj mums piekļūt vērtīgai informācijai par vēsturiskām mikroorganismu kopām. Līdz šim nav veikti pētījumi par vēsturisko mikrobiomu Latvijas arheoloģiskajos paraugos. Savā darbā esmu pētījusi senās DNS (aDNS) datu kopas un mikrobioma sastāvu arheoloģiskos pēcviduslaiku cilvēka kaulu, zobu un zobakmens paraugos Latvijā, Ziemeļeiropā, kas ir datēti ar mūsu ēras 15.–17.gadsimtu. Kopumā šajā darbā tika pētīts vēsturiskais cilvēka mikrobioms, novērtēta seno biomolekulu saglabāšanas pakāpe dažādos pēcviduslaiku arheoloģiskajos paraugos un raksturota iespējamā apbedījumu vides mikroorganismu DNS ietekme uz seno mikrobiomu rekonstrukciju. Ar seno mikrobiomu saistīto datu uzkrāšana veicina šīs pētniecības jomas progresu.The area of ancient human microbiome research has evolved rapidly over the past few decades. Modern sequencing technologies enable us to access the valuable information about historic microbial communities. Until now there have been no studies on historic microbiome in archaeological samples from Latvia. Within my work, I have investigated ancient DNA (aDNA) datasets and microbiome composition of human postmedieval archaeological bone, tooth and dental calculus samples in Latvia, Northern Europe, dated 15th–17th century AD. Overall, this work explored the historic human-related microbiota, preservation of ancient biomolecules in different postmedival archaeological samples, and a possible impact of the burial environment and environmental DNA on ancient microbiome reconstruction. Accumulating ancient microbiome-related data contribute to the progress of this research area
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
Trepanation in Anthropological Materials of Latvia.
No full textBakalaura darbs „Trepanācijas Latvijas antropoloģiskajā materiālā” ir apkopojošs pētījums par trepanācijas gadījumiem Latvijas teritorijā. Darbā ir apkopota infromācija par trepanācijas gadījumiem sākot ar akmens laikmetu līdz 15. gadsimtam.
Darba mērķis ir: balstoties uz arheoloģiskajos izrakumos iegūto antropoloģisko materiālu, analizēt Latvijā konstatētās galvaskausu trepanācijas.
Trepanācija ir ķirurģiska operācija, kurā tiek atvērts kāds kaula dobums. Visbiežāk ar trepanācijas palīdzību tiek atvērts galvaskauss, lai veiktu indivīda ārstēšanu vai īstenotu kādu rituālu.
Izstrādājot darbu, tika apkopotas ziņas par trepanācijas vispārēju teoriju, par tās veikšanu, kā arī par iemesliem, kāpēc trepanācija tiek īstenota. Tika apkopoti materiāli par Latvijas trepanācijām, kuri tika salīdzināti ar citās valstīs konstatētajiem gadījumiem.The graduation paper „Trepanations in Anthropological Materials of Latvia” is summary research about cases of trepanations of Latvia. Information about trepanations from Stone Age till 15. century is summarized in this paper.
The aim of this paper is: based on anthropological material which is got from archeological excavations, analyze established skull trepanations from Latvia.
Trepanation is surgical operation when some cavity of bone is opened. Most often skull is opened by trepanation, to perform retreatment of human or to realize some ritual.
By developing this paper, information about theory of trepanation, about making trepanations and about reasons why trepanation is made, is collected. Cases of trepanation of Latvia is collected and comparised with information about cases from other countries
