GIS-based palaeogeographical reconstructions of the Baltic Sea shores in Estonia and adjoining areas during the Stone Age
Väitekirja elektrooniline versioon ei sisalda publikatsiooneLäänemeremaadest on leitud palju kiviaegseid asulakohti, mille arheoloogiline leiumaterjal viitab rannasidusale elatusviisile, kuid mis asuvad tänapäeval merest kaugel. Käesolevas doktoritöös rekonstrueeriti meretaseme muutused, paleorannavööndid ja –maastikud kiviaegsete asulakohtade ümbruses Narva-Lauga klindilahes, Tallinna kesklinnas ja Ruhnu saarel, et välja selgitada nende asulakohtade paiknemine omaaegses maastikus. Selleks kasutati geoinfosüsteemipõhist lähenemist, milles korreleeriti ruumiliselt ja ajaliselt mitmed loodusteaduslikud ning arheoloogilised andmestikud.
Paleogeograafiliste rekonstruktsioonide alusel leiti, et Narva-Lauga piirkonnas oli kiviaegne küttide-kalurite-korilaste asustus seotud seal u. 7000-5000 aastat tagasi eksisteerinud ulatusliku laguuni kallastega. Ruhnu saarel rajati u. 7200 ja 6200 aastat tagasi kiviaegsed jahilaagrid otse rannavööndisse, vaid mõne meetri võrra meretasemest kõrgemale. Samuti Tallinna kesklinnas Vabaduse väljaku alal 5000 aasta eest, mis sel ajal moodustas osa avatud lahe rannast. Rekonstruktsioonid näitasid, et asustusmuster muutus u. 4700 aastat tagasi, mil asulakohti hakati rajama sisemaale seoses üleminekuga põlluharimisele ja karjakasvatusele.
Töö tulemused kinnitavad loodusteaduslike andmete ja geoinformaatiliste meetoditega arheoloogilisi hüpoteese Eesti ja lähialade kiviaegse asustuse paiknemise kohta, täpsustavad rannasidusa elatusviisiga ajajärgu kestust ning kiviaja inimeste elupaigaeelistusi ja kohastumust erinevat tüüpi rannikutel. Seeläbi aitab töö kaasa kultuuripärandi tõlgendamisele ja väärtustamisele.In the Baltic Sea region many Stone Age settlement sites have been found, which show evidence for shore-connected habitation, but are presently located far from the seashore. In this thesis, past sea level changes and palaeolandscapes around Stone Age settlement sites in Narva-Luga lowland, Tallinn city centre and on Ruhnu Island were reconstructed in order to define the location of the settlements compared to their contemporary shoreline and coastal setting. Geographic information system approach was used for palaeogeographical modelling based on spatio-temporal correlation of datasets originating from several natural science and archaeological research disciplines.
Palaeogeographical reconstructions show that in Narva-Luga area hunter-fisher-gatherer settlements were located on the shores of a large lagoon, which existed there c. 7000-5000 years ago. On Ruhnu Island hunting and fishing camps were established directly in the beach zone, only a few metres above sea level at about 7200 and 6200 years ago. Similarly, in Tallinn, 5000 years ago a camp was established on the beach of the wide palaeo-bay, which shore crossed the city centre at that time. The reconstructions showed that this settlement pattern changed c. 4700 years ago, when areas away from the coast were chosen for habitation, indicating a shift in subsistence strategy towards farming.
Using data of natural sciences and methods of geoinformatics, the results of this thesis prove archaeological hypotheses about Stone Age settlement pattern and preferred settlement locations, specify the period of the shore-bound habitation and adaption of Stone Age people on different types of coasts. Thus this study contributes to interpretation and valuation of cultural heritage

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
