description Publicationkeyboard_double_arrow_right Article 2018 EstoniaPublisher:Informa UK Limited Funded by:EC | UPTAKEEC| UPTAKEAuthors: Kakabadze, Shota; Makarychev, Andrey;Kakabadze, Shota; Makarychev, Andrey;The article seeks to analyze discourses of two Orthodox Churches—Georgian (GOC) and Russian (ROC)—from the vantage point of their various interconnections with Europe and the ensuing representations of Europe framed in religious terms. Of particular salience are relations between ROC and GOC, on the one hand, and the Roman Catholic Church, on the other, as well as the positioning of both ROC and GOC within the global community of Orthodox Churches. The analyzed political circumstances force religious hierarchs of both institutions, even if they share the similar ambivalence toward the West, to differently reproduce the image of Europe. The broader geopolitical picture puts the GOC in the position of supporting government’s foreign policy agenda which goes in opposition to the Kremlin, in spite of the fact that the former has a lot of common with the Moscow Patriarchate when it comes to criticism toward the Western liberal value systems.

In this paper we introduce a new natural language processing dataset and benchmark for predicting prosodic prominence from written text. To our knowledge this will be the largest publicly available dataset with prosodic labels. We describe the dataset construction and the resulting benchmark dataset in detail and train a number of different models ranging from feature-based classifiers to neural network systems for the prediction of discretized prosodic prominence. We show that pre-trained contextualized word representations from BERT outperform the other models even with less than 10% of the training data. Finally we discuss the dataset in light of the results and point to future research and plans for further improving both the dataset and methods of predicting prosodic prominence from text. The dataset and the code for the models are publicly available. Comment: NoDaLiDa 2019 camera ready

The thesis is focused on the following landmarks in the history of Estonia: The World War II, the Stalin's repressions, the time under the Soviet rule, the collapse of the Soviet union and the sovereignty of Estonia stemming from it. It is these periods and landmarks which may originate different theoretical interpretations of history in terms of the framework of Estonian Republic. Estonian as well as Russian textbooks of history for gymnasium can serve as sources and media for interpretations. Topicality and actual value of the thesis today is certain and evident owing to the reasons. Since it is perfectly possible to influence and shape the worldviews and perspectives of a personality especially during one's reaching the age of puberty. History textbooks or as in the case Estonian textbooks on history in particular are the means enabling to create certain viewpoints and perspectives. School plays the role of institution with its curricula realizing the mentioned function. The young among the local Estonians as well as Russian-speaking minorities may have different perspectives and viewpoints. Besides that, the Estonian textbooks used do not necessarily reflect the historical facts the same way, neither give similar understanding of the same landmarks of significance. Given the mentioned assumptions it is important to learn whether the history textbooks published in this particular time lapse in Estonia have possibly influenced in certain way and shaped different understandings of the past events or on the contrary, suggest the same identical worldview and perspective or imply several alternative possible interpretations. There have been made certain conclusions with the help of analysis made on the basis of comparisons and juxtaposing. The conclusions found are that Estonian textbooks can shape and create different viewpoints being in stark contrast with one another. There are differences between the Estonians textbooks written in Russian and Estonian as well as numerous differences between the textbooks written in Estonian. It is worth mentioning that the difference between the textbooks written in Russian language are negligible and minor.

In this paper, using Estonian Community Innovation Survey data, we study the role of R&D, capital accumulation, and innovation output on pro- ductivity for entrants and incumbents. We find that the impact of R&D invest- ment on labour productivity is larger for the entrants compared to the incum- bents. Entrants are found to be more productive and more heterogeneous in their total factor productivity (TFP) than the incumbents. Moreover, entrants who innovate are on average, in terms of TFP, 25% more productive than the entrants who do not, while the corresponding figure for the incumbents is 7%. In addition, it is mostly the incumbents who benefit from within-industry knowledge that is produced outside their own firm. Finally, for both entrants and incumbents, em- bodied technological change through capital accumulation is found to be more effective in generating productivity growth than R&D expenditure.

Uurimuse eesmärk on selgitada, kas ja kuidas riiklik rahvuspoliitika mõjutas inimeste käitumist ja vastupidi – mil määral mõjutasid inimeste valikud riikide tegevust. Valimisse hõlmatud inimestest suurem osa puutus uuritaval perioodil kokku nelja riigi – Venemaa keisririigi, Eesti Vabariigi, Nõukogude Liidu ja Saksamaa – rahvuspoliitikaga. Nende põhimõtteliselt erineva rahvuspoliitikaga riikide käsitlemine võimaldab tuvastada rahvuse ühiskondliku tähenduse universaalseid jooni. Eesmärgi täitmiseks analüüsiti inimeste eluloolisi andmeid, seadusandlust ja rahvuspoliitikat puudutavat dokumentatsiooni ning ühiskondlikke olusid puudutavaid allikaid. Doktoritööst selgus, et üksikisikute rahvuskuuluvuse formaalne määramine osutus 20. sajandi esimesel poolel keeruliseks nii riikide kui ka inimeste jaoks, sest puudusid selged kriteeriumid viimaste rahvuspõhiseks kategoriseerimiseks, ühtsed arusaamad rahvuste olemusest ning takistav tegur oli ka mõlema poole pragmaatiliste kaalutluste domineerimine rahvuse määramisel. Mida suurem oli rahvuskuuluvuse formaalne tähtsus, seda enam olid üksikisikute valikud tingitud olukorrast ning märksa vähem nende harjumuspärasest keele- ja kultuurikeskkonnast. Seetõttu ei õnnestunud riikidel peaaegu kunagi soovitud määral rakendada essentsialistlikke ja objektiivsusele pretendeerinud rahvuse määramise kriteeriume, isegi kui see oli eesmärk ja taolisi põhimõtteid seadustega kehtestada püüti. Samuti ei olnud riigid objektiivsuse rakendamisel põhimõttelised ja järjekindlad, vaid kohandasid seisukohti vastavalt pragmaatilistele huvidele ning inimeste käitumisele. Üksikisikute valikutel oli riiklikele poliitikatele märkimisväärne mõju, ehkki arvuliselt oli muutliku ja ebamäärase rahvuskuuluvusega inimesi ühiskonnas marginaalselt. This dissertation focuses on the meaning of ethnicity in the relations between individuals and states in the first half of the 20th century using the biographical data of people who resettled from Estonia to Germany in 1941 as a sample. The aim of this study is to explain whether and how ethnopolitics of the states influenced the behaviour of individuals and vice versa – to what extent individual choices influenced state policy. Most people in the sample were affected by the ethnopolitics of four states: Russian Empire, Estonian Republic, Soviet Union, and Germany. Analysing the states with fundamentally different ethnopolitics enables to identify universal characteristics of the role of ethnicity in the society. To fulfil the aim, biographical data, legislation, and documentation about ethnopolitics as well as sources about the social conditions were analysed. The dissertation shows that fixing individuals’ ethnicity turned out to be difficult for both parties – the states and individuals – since there were no clear criteria for ethnic categorisation and no common understanding about the nature of ethnicity. Pragmatic considerations of both parties also turned out to be an obstacle. The more formal importance ethnicity had, the more individuals made choices dependent on the situation and not so much on their customary lingual and cultural environment. Therefore, the states almost always failed to implement essentialist and objective criteria in fixing individuals’ ethnicity in a desired manner, even if such criteria were their aim and established by law. Furthermore, the authorities of the states were neither principled nor consistent in applying objective criteria. The states had to adapt their stances to their own pragmatic interests and according to the behaviour of individuals instead. Thus, individual choices had a remarkable impact on ethnopolitics, although people with dynamic and vague ethnic identity formed a marginal group in the society. https://www.ester.ee/record=b5450809

There are different approaches (e.g., econometrics and machine learning) for predicting stock returns. However, it is non-trivial to find an approach which works the best. In this paper, we make a thorough analysis of the predictive accuracy of different machine learning and econometric approaches for predicting the returns and volatilities on the OMX Baltic Benchmark price index, which is a relatively less researched stock market. Our results show that the machine learning methods, namely the support vector regression and k-nearest neighbours, predict the returns better than autoregressive moving average models for most of the metrics, while for the other approaches, the results were not conclusive. Our analysis also highlighted that training and testing sample size plays an important role on the outcome of machine learning approaches.

Töö käigus koostati ankeet, mille abil koguti tekstilist materjali ligi 300-st vabatahtlikust koosnevalt mugavusvalimilt. Kogutud tekstid sisaldasid nii etteantud pildi kirjeldust kui ka vabalt valitud sündmuse või mälestuse kirjeldust. Valimis osalenute emotsionaalset seisundit mõõdeti EEK-2 skriiningtesti abil. Ligi 42% isikutest ületas depressiooni ning ligi 30% isikutest ärevuse alaskaala riskilävendi. Esialgsed eksperimendid masinõppe mudelitega, mis püüdsid ennustada, kas inimese EEK-2 skoor ületab depressiooni ja/või ärevuse riskilävendi, edukaid tulemusi ei andnud. Kokkuvõttes tundub, et etteantud pildi kirjeldamine ei ole sobivaim viis soovitud andmestiku kogumiseks ja pigem peaks kasutama selliseid kirjutamise ülesandeid, mis oleks inimese endaga rohkem seotud.

Or a country where political violence is used against members of a parliamentary committee during a committee meeting – as was the case in Finland in 1930? Why did the Estonian Social Democrats support the 1934 coup and why did the Finnish Swedes defend the Finnish Communists? Why could Estonia not find any allies except Latvia in the 1920s and 1930s, and why was Finland left without allies in the Winter War? Why did Estonia and Finland not behave in the same way in the autumn of 1939, and why did the United Kingdom, Canada, Australia, and New Zealand declare war on Finland in 1941? The answers to these questions lie in the relationships between democracy and security, which is exactly the topic of my dissertation. Based on the works of different philosophers, it is possible to show that democracy and security are interdependent. The relationship between democracy and security can be reduced to the classic dilemmas between freedom and security, freedom and sovereignty, and sovereignty and security. Although it is not possible to solve these dilemmas definitively, the solution can be improved indefinitely. I argue that the way in which democratic societies resolve these dilemmas does not depend on democratic culture or on the wisdom inherent in people, but on the perceptions of the majorities of democratic societies, which in turn depend primarily on historical experience. The theoretical explanation proposed in my dissertation helps to understand why Estonia’s and Finland’s quests for security failed in 1918–1948 and why Estonia and Finland made different choices at the turning points of their history. The behaviour of Estonia’s leaders during the events of 1939 and 1940 also becomes understandable. Hopefully, my dissertation will contribute to a fair judgement of the activities of Konstantin Päts and Johan Laidoner, and to reconciling Estonian society on the question of whether they were heroes or villains. However, the most important aim is to contribute to an understanding of just how fragile democracy and security can be, how they depend on each other and, in particular, how they depend on historical experience. Kas saab pidada demokraatlikuks riiki, mille pealinnas kehtib pidev erakorraline seisukord – nagu oli Eesti aastatel 1918–1934? Või riiki, kus parlamendikomisjoni liikmete vastu kasutatakse poliitilist vägivalda komisjoni istungi toimumise ajal – nagu oli Soome aastal 1930? Miks Eesti sotsiaaldemokraadid toetasid 1934. aasta riigipööret ja miks soomerootslased kaitsesid Soome kommuniste? Miks ei õnnestunud 1920-ndate ja 1930-ndate Eestil leida ühtegi liitlast peale Läti ja miks jäi Soome talvesõjas ilma liitlasteta? Miks Eesti ja Soome 1939. aasta sügisel ühtemoodi ei käitunud ja miks Ühendkuningriik, Kanada, Austraalia ja Uus-Meremaa 1941. aastal Soomele sõja kuulutasid? Vastus peitub demokraatia ja julgeoleku vahelistes seostes, mida minu väitekiri uuribki. Erinevate filosoofide töödele tuginedes on võimalik näidata, et demokraatia ja julgeolek sõltuvad vastastikku üksteisest. Demokraatia ja julgeoleku vaheline seos on taandatav klassikalistele dilemmadele vabaduse ja julgeoleku, vabaduse ja suveräänsuse ja suveräänsuse ja julgeoleku vahel. Kuigi dilemmasid ei ole võimalik lõplikult lahendada, on lahendust võimalik lõputult täiustada. Ma väidan, et see, kuidas demokraatlikud ühiskonnad neid dilemmasid lahendavad, ei sõltu mitte demokraatlikust kultuurist või rahvale omasest tarkusest, vaid demokraatlike ühiskondade enamuste arusaamadest, mis omakorda sõltuvad eelkõige ajaloolisest kogemusest. Minu väitekirjas välja pakutud teoreetiline selgitus aitab mõista, miks Eesti ja Soome julgeolekuotsingud aastatel 1918–1948 läbi kukkusid ja miks Eesti ja Soome oma ajaloo pöördepunktides erinevaid valikuid tegid. Mõistetavaks muutub ka Eesti riigijuhtide käitumine 1939. ja 1940. aasta sündmuste ajal. Loodetavasti aitab minu väitekiri kaasa õiglase hinnangu andmisele Konstantin Pätsi ja Johan Laidoneri tegevusele ja Eesti ühiskonna lepitamisele küsimuses, kas tegemist oli kangelaste või kurjategijatega. Kõige tähtsam on siiski aidata kaasa mõistmisele, kuivõrd haprad võivad olla demokraatia ja julgeolek, kuidas nad vastastikku üksteisest sõltuvad ja eriti – kuidas nad sõltuvad ajaloolisest kogemusest. https://www.ester.ee/record=b5391015

The current thesis studies how the archaeological and folkloristic information relate to each other and what are the possibilities to use theses as a combined. Archaeological research has focused on the material remains from the past; the folklorists, however, study the information that has mainly been passed on orally. When the academic interest lies in the past culture as a whole, the use of different sources will grant richer and more comprehensive knowledge. The case-study of thesis that is covering the material from Estonia is analysing the information about origin of and finds associated with human remains in wetlands. The main focus has been on mires. This kind of intriguing and unstudied topic was chosen because of folk songs that describe burying in mires. Also, in the place-lore there are stories about burials in mires, as well as depictions of drowning in wetlands. For archaeologist, this raises a question, whether this folklore could reflect the events that have led to bog bodies? Additionally, the place-lore describes unearthing of human remains from waterlogged soil of which there is no archaeological documentation. Attempts to find new archaeological record for some of these place-lore sites were unfortunately unsuccessful. These fieldworks illustrate how complicated is it to discover archaeological finds from wetlands. At the same time, the work with archive sources and literature showed that there are previous archaeologically documented finds of human remains from wetlands. The age, context and way of emerge of these human remains has been very different. The archaeological excavation conducted as part of this research in Alasoo Varajemägi revealed finds in peat originating from the pyre. It seems that items left behind from cremation burials were taken into a former lake. There was no record of this kind of behaviour from the Viking Age previously documented in Estonia. Therefore, the study represents information in archaeology and folkloristics concerning human remains in wetlands. The information of both records is quite diverse, but the systematic study has brought them closer and at the same time has helped to understand the character how the archaeological and folkloristic information has been emerged, transmitted and stored. On täiesti loomulik, et erinevad minevikust pärinevad allikaliigid kannavad endas edasi erinevat informatsiooni. Käesolevas doktoritöös vaadeldakse, kuidas suhestuvad omavahel arheoloogiline ja rahvaluuleline teave ning millised on võimalused nende kooskasutuseks. Arheoloogide uurimistöö on keskendunud mineviku materiaalsetele jäänustele, rahvaluuleteadlased aga uurivad informatsiooni, mis on üle põlvkondade edasi kandunud enamasti suusõnaliselt. Kui teadlase uurimisobjektiks on mineviku kultuur terviklikult, siis aitab erinevate allikate kasutus saada möödunud aegadest palju rikkama ja mitmekihilisema arusaama. Eesti materjali käsitleva doktoritöö juhtumuuring vaatleb teavet inimjäänuste tekkest ja vastavatest leidudest märgaladel. Peamise tähelepanu all on olnud sood. Niisuguse intrigeeriva ja senikäsitlemata teemavaliku põhjustasid sohu matmisi kirjeldavad rahvalaulud. Ka kohapärimuses on nii jutte matmisest sohu kui ka kirjeldusi uppumistest märgaladel. Arheoloogi jaoks tõstatab see küsimuse, kas ja mil määral võib niisugune pärimus kajastada sündmusi, mis on maha jätnud soolaipu? Lisaks kirjeldab kohapärimus inimsäilmete avastamist liigniiskest pinnasest, mille kohta arheoloogilist dokumentatsiooni ei leidu. Katse leida osadest pärimuspaikadest uusi arheoloogilisi tõendeid kahjuks ei õnnestunud. Mainitud välitööd illustreerivad hästi, kui keerukas ja raske on avastada märgaladelt arheoloogiliste leide. Samas, töö arhiiviallikate ja kirjandusega näitas, et eelnevalt on ka arheoloogiliselt registreeritud inimjäänuste leide liigniiskest pinnasest. Need leiud on aga väga erineva vanuse, konteksti ja tekkepõhjusega. Doktoritöö raames tehtud arheoloogiliste kaevamistega õnnestus Alasoo Varajemäel tuvastada turbas asuvaid leide, mis pärinesid tuleriidalt. Näib, et põletusmatustest järele jäänud asju viidi endisaegsesse järvevette. Niisugusest viikingiaegsest käitumisest Eesti arheoloogias seni tõendeid ei olnud. Seega esitab uurimus märgaladel leiduvate inimjäänustega seonduvat arheoloogilist ja rahvaluulelist informatsiooni. Mõlemas allikaliigis esinev informatsioon on küll üsna eriilmeline, kuid süstemaatiline uurimine on vähendanud nende vahelist lõhet ja samas aidanud mõtestada ka eripära, kuidas need allikad on tekkinud, edasi kandunud ning talletunud.

Today, sheep husbandry forms a small, but important part in Estonian agriculture. By using zooarchaeological and genetic data, the aim of the dissertation is to study sheep husbandry and the development of maternal lineages in Estonia and more widely, in the Baltic Sea region, from the Middle Bronze Age (c. 1200 BC) until the present-day. The zooarchaeological part of the thesis focuses on animal consumption in Late Iron Age and medieval Viljandi and Karksi, and tackles the changes in proportion and exploitation of faunal resources over time. The genetic part of the research aims to analyse the maternally inherited mitochondrial DNA both in the ancient populations and modern Kihnu native sheep. The results of the study indicate that, starting from the Bronze Age, sheep husbandry and utilisation in Estonia has been rather persistent. Nonetheless, changes occurred, which could mainly be related to two distinct periods. Firstly, the transition from prehistory to the Middle Ages, including the 13th century Crusades. Genetically it is expressed in population expansion, possibly linked to the overall increase in human population and the demand for meat supplies. Moreover, the growth of the populations seems to have relied on local herds, while the effect of imported animals was probably insignificant. Secondly, changes came along with the beginning of the large-scale breeding in the 19th century, aimed to improve the local production of mutton and wool. With slightly decreased genetic diversity, the local sheep, including the Kihnu native sheep, have been preserved up to the present. Lammas (Ovis aries) on alates hilispronksiajast olnud üks enimkasvatatud kariloomi Eestis. Tänapäeval moodustab lambakasvatus Eestis väikese, kuid järjest olulisema osa põllumajandusest. Tuginedes zooarheoloogilisele leiuainesele ja geneetilisele andmestikule, on väitekirja eesmärk uurida lambakasvatust ning lammaste emaliinide ajalugu Eestis ja laiemalt Läänemere kultuuriruumis keskmisest pronksiajast (u 1200 eKr) tänapäevani. Töö zooarheoloogiline pool keskendub hilisrauaajale ja keskajale Viljandis ja Karksis ning loomsete saaduste tarbimisharjumustele ajas ja ruumis. Geneetiline osa analüüsib emaliini pidi pärandatavat mitokondriaalset DNA-d vanades lambaleidudes ja ka tänapäevastes Kihnu maalammastes. Uurimusest selgub, et lambakasvatus ja lammaste tarvitamine toiduks on Eestis olnud pronksiajast peale üsna järjepidev. Siiski ilmnevad mõned murranguajad, millele tuleb seletust otsida laiemal ajaloolisel taustal. Need muudatused seostuvad kahe perioodiga. Esiteks üleminek muinasajalt keskajale koos 13. sajandi alguse ristisõdadega. Geneetilises andmestikus väljendub see lambapopulatsiooni suurenemises, mis on toimunud kohaliku talumajanduse ja olemasolevate loomade baasil, ning mis võib olla tingitud sellest, et keskajal kasvas koos rahvaarvuga ka kariloomade hulk. Teine murrang ilmneb seoses suure tõuaretusega 19. sajandil, mil eeskätt Lääne-Euroopast sisse toodud tõugudega hakati kohalike lammaste liha- ja villatootlikkust parandama. Hoolimata sellest on algupärased põliste tunnustega maalambad, eeskätt Kihnu maalammas, säilinud tänapäevani, kuigi mõnevõrra väiksema geneetilise mitmekesisusega.

description Publicationkeyboard_double_arrow_right Article 2018 EstoniaPublisher:Informa UK Limited Funded by:EC | UPTAKEEC| UPTAKEAuthors: Kakabadze, Shota; Makarychev, Andrey;Kakabadze, Shota; Makarychev, Andrey;The article seeks to analyze discourses of two Orthodox Churches—Georgian (GOC) and Russian (ROC)—from the vantage point of their various interconnections with Europe and the ensuing representations of Europe framed in religious terms. Of particular salience are relations between ROC and GOC, on the one hand, and the Roman Catholic Church, on the other, as well as the positioning of both ROC and GOC within the global community of Orthodox Churches. The analyzed political circumstances force religious hierarchs of both institutions, even if they share the similar ambivalence toward the West, to differently reproduce the image of Europe. The broader geopolitical picture puts the GOC in the position of supporting government’s foreign policy agenda which goes in opposition to the Kremlin, in spite of the fact that the former has a lot of common with the Moscow Patriarchate when it comes to criticism toward the Western liberal value systems.

In this paper we introduce a new natural language processing dataset and benchmark for predicting prosodic prominence from written text. To our knowledge this will be the largest publicly available dataset with prosodic labels. We describe the dataset construction and the resulting benchmark dataset in detail and train a number of different models ranging from feature-based classifiers to neural network systems for the prediction of discretized prosodic prominence. We show that pre-trained contextualized word representations from BERT outperform the other models even with less than 10% of the training data. Finally we discuss the dataset in light of the results and point to future research and plans for further improving both the dataset and methods of predicting prosodic prominence from text. The dataset and the code for the models are publicly available. Comment: NoDaLiDa 2019 camera ready

The thesis is focused on the following landmarks in the history of Estonia: The World War II, the Stalin's repressions, the time under the Soviet rule, the collapse of the Soviet union and the sovereignty of Estonia stemming from it. It is these periods and landmarks which may originate different theoretical interpretations of history in terms of the framework of Estonian Republic. Estonian as well as Russian textbooks of history for gymnasium can serve as sources and media for interpretations. Topicality and actual value of the thesis today is certain and evident owing to the reasons. Since it is perfectly possible to influence and shape the worldviews and perspectives of a personality especially during one's reaching the age of puberty. History textbooks or as in the case Estonian textbooks on history in particular are the means enabling to create certain viewpoints and perspectives. School plays the role of institution with its curricula realizing the mentioned function. The young among the local Estonians as well as Russian-speaking minorities may have different perspectives and viewpoints. Besides that, the Estonian textbooks used do not necessarily reflect the historical facts the same way, neither give similar understanding of the same landmarks of significance. Given the mentioned assumptions it is important to learn whether the history textbooks published in this particular time lapse in Estonia have possibly influenced in certain way and shaped different understandings of the past events or on the contrary, suggest the same identical worldview and perspective or imply several alternative possible interpretations. There have been made certain conclusions with the help of analysis made on the basis of comparisons and juxtaposing. The conclusions found are that Estonian textbooks can shape and create different viewpoints being in stark contrast with one another. There are differences between the Estonians textbooks written in Russian and Estonian as well as numerous differences between the textbooks written in Estonian. It is worth mentioning that the difference between the textbooks written in Russian language are negligible and minor.

In this paper, using Estonian Community Innovation Survey data, we study the role of R&D, capital accumulation, and innovation output on pro- ductivity for entrants and incumbents. We find that the impact of R&D invest- ment on labour productivity is larger for the entrants compared to the incum- bents. Entrants are found to be more productive and more heterogeneous in their total factor productivity (TFP) than the incumbents. Moreover, entrants who innovate are on average, in terms of TFP, 25% more productive than the entrants who do not, while the corresponding figure for the incumbents is 7%. In addition, it is mostly the incumbents who benefit from within-industry knowledge that is produced outside their own firm. Finally, for both entrants and incumbents, em- bodied technological change through capital accumulation is found to be more effective in generating productivity growth than R&D expenditure.

Uurimuse eesmärk on selgitada, kas ja kuidas riiklik rahvuspoliitika mõjutas inimeste käitumist ja vastupidi – mil määral mõjutasid inimeste valikud riikide tegevust. Valimisse hõlmatud inimestest suurem osa puutus uuritaval perioodil kokku nelja riigi – Venemaa keisririigi, Eesti Vabariigi, Nõukogude Liidu ja Saksamaa – rahvuspoliitikaga. Nende põhimõtteliselt erineva rahvuspoliitikaga riikide käsitlemine võimaldab tuvastada rahvuse ühiskondliku tähenduse universaalseid jooni. Eesmärgi täitmiseks analüüsiti inimeste eluloolisi andmeid, seadusandlust ja rahvuspoliitikat puudutavat dokumentatsiooni ning ühiskondlikke olusid puudutavaid allikaid. Doktoritööst selgus, et üksikisikute rahvuskuuluvuse formaalne määramine osutus 20. sajandi esimesel poolel keeruliseks nii riikide kui ka inimeste jaoks, sest puudusid selged kriteeriumid viimaste rahvuspõhiseks kategoriseerimiseks, ühtsed arusaamad rahvuste olemusest ning takistav tegur oli ka mõlema poole pragmaatiliste kaalutluste domineerimine rahvuse määramisel. Mida suurem oli rahvuskuuluvuse formaalne tähtsus, seda enam olid üksikisikute valikud tingitud olukorrast ning märksa vähem nende harjumuspärasest keele- ja kultuurikeskkonnast. Seetõttu ei õnnestunud riikidel peaaegu kunagi soovitud määral rakendada essentsialistlikke ja objektiivsusele pretendeerinud rahvuse määramise kriteeriume, isegi kui see oli eesmärk ja taolisi põhimõtteid seadustega kehtestada püüti. Samuti ei olnud riigid objektiivsuse rakendamisel põhimõttelised ja järjekindlad, vaid kohandasid seisukohti vastavalt pragmaatilistele huvidele ning inimeste käitumisele. Üksikisikute valikutel oli riiklikele poliitikatele märkimisväärne mõju, ehkki arvuliselt oli muutliku ja ebamäärase rahvuskuuluvusega inimesi ühiskonnas marginaalselt. This dissertation focuses on the meaning of ethnicity in the relations between individuals and states in the first half of the 20th century using the biographical data of people who resettled from Estonia to Germany in 1941 as a sample. The aim of this study is to explain whether and how ethnopolitics of the states influenced the behaviour of individuals and vice versa – to what extent individual choices influenced state policy. Most people in the sample were affected by the ethnopolitics of four states: Russian Empire, Estonian Republic, Soviet Union, and Germany. Analysing the states with fundamentally different ethnopolitics enables to identify universal characteristics of the role of ethnicity in the society. To fulfil the aim, biographical data, legislation, and documentation about ethnopolitics as well as sources about the social conditions were analysed. The dissertation shows that fixing individuals’ ethnicity turned out to be difficult for both parties – the states and individuals – since there were no clear criteria for ethnic categorisation and no common understanding about the nature of ethnicity. Pragmatic considerations of both parties also turned out to be an obstacle. The more formal importance ethnicity had, the more individuals made choices dependent on the situation and not so much on their customary lingual and cultural environment. Therefore, the states almost always failed to implement essentialist and objective criteria in fixing individuals’ ethnicity in a desired manner, even if such criteria were their aim and established by law. Furthermore, the authorities of the states were neither principled nor consistent in applying objective criteria. The states had to adapt their stances to their own pragmatic interests and according to the behaviour of individuals instead. Thus, individual choices had a remarkable impact on ethnopolitics, although people with dynamic and vague ethnic identity formed a marginal group in the society. https://www.ester.ee/record=b5450809

There are different approaches (e.g., econometrics and machine learning) for predicting stock returns. However, it is non-trivial to find an approach which works the best. In this paper, we make a thorough analysis of the predictive accuracy of different machine learning and econometric approaches for predicting the returns and volatilities on the OMX Baltic Benchmark price index, which is a relatively less researched stock market. Our results show that the machine learning methods, namely the support vector regression and k-nearest neighbours, predict the returns better than autoregressive moving average models for most of the metrics, while for the other approaches, the results were not conclusive. Our analysis also highlighted that training and testing sample size plays an important role on the outcome of machine learning approaches.

Töö käigus koostati ankeet, mille abil koguti tekstilist materjali ligi 300-st vabatahtlikust koosnevalt mugavusvalimilt. Kogutud tekstid sisaldasid nii etteantud pildi kirjeldust kui ka vabalt valitud sündmuse või mälestuse kirjeldust. Valimis osalenute emotsionaalset seisundit mõõdeti EEK-2 skriiningtesti abil. Ligi 42% isikutest ületas depressiooni ning ligi 30% isikutest ärevuse alaskaala riskilävendi. Esialgsed eksperimendid masinõppe mudelitega, mis püüdsid ennustada, kas inimese EEK-2 skoor ületab depressiooni ja/või ärevuse riskilävendi, edukaid tulemusi ei andnud. Kokkuvõttes tundub, et etteantud pildi kirjeldamine ei ole sobivaim viis soovitud andmestiku kogumiseks ja pigem peaks kasutama selliseid kirjutamise ülesandeid, mis oleks inimese endaga rohkem seotud.

Or a country where political violence is used against members of a parliamentary committee during a committee meeting – as was the case in Finland in 1930? Why did the Estonian Social Democrats support the 1934 coup and why did the Finnish Swedes defend the Finnish Communists? Why could Estonia not find any allies except Latvia in the 1920s and 1930s, and why was Finland left without allies in the Winter War? Why did Estonia and Finland not behave in the same way in the autumn of 1939, and why did the United Kingdom, Canada, Australia, and New Zealand declare war on Finland in 1941? The answers to these questions lie in the relationships between democracy and security, which is exactly the topic of my dissertation. Based on the works of different philosophers, it is possible to show that democracy and security are interdependent. The relationship between democracy and security can be reduced to the classic dilemmas between freedom and security, freedom and sovereignty, and sovereignty and security. Although it is not possible to solve these dilemmas definitively, the solution can be improved indefinitely. I argue that the way in which democratic societies resolve these dilemmas does not depend on democratic culture or on the wisdom inherent in people, but on the perceptions of the majorities of democratic societies, which in turn depend primarily on historical experience. The theoretical explanation proposed in my dissertation helps to understand why Estonia’s and Finland’s quests for security failed in 1918–1948 and why Estonia and Finland made different choices at the turning points of their history. The behaviour of Estonia’s leaders during the events of 1939 and 1940 also becomes understandable. Hopefully, my dissertation will contribute to a fair judgement of the activities of Konstantin Päts and Johan Laidoner, and to reconciling Estonian society on the question of whether they were heroes or villains. However, the most important aim is to contribute to an understanding of just how fragile democracy and security can be, how they depend on each other and, in particular, how they depend on historical experience. Kas saab pidada demokraatlikuks riiki, mille pealinnas kehtib pidev erakorraline seisukord – nagu oli Eesti aastatel 1918–1934? Või riiki, kus parlamendikomisjoni liikmete vastu kasutatakse poliitilist vägivalda komisjoni istungi toimumise ajal – nagu oli Soome aastal 1930? Miks Eesti sotsiaaldemokraadid toetasid 1934. aasta riigipööret ja miks soomerootslased kaitsesid Soome kommuniste? Miks ei õnnestunud 1920-ndate ja 1930-ndate Eestil leida ühtegi liitlast peale Läti ja miks jäi Soome talvesõjas ilma liitlasteta? Miks Eesti ja Soome 1939. aasta sügisel ühtemoodi ei käitunud ja miks Ühendkuningriik, Kanada, Austraalia ja Uus-Meremaa 1941. aastal Soomele sõja kuulutasid? Vastus peitub demokraatia ja julgeoleku vahelistes seostes, mida minu väitekiri uuribki. Erinevate filosoofide töödele tuginedes on võimalik näidata, et demokraatia ja julgeolek sõltuvad vastastikku üksteisest. Demokraatia ja julgeoleku vaheline seos on taandatav klassikalistele dilemmadele vabaduse ja julgeoleku, vabaduse ja suveräänsuse ja suveräänsuse ja julgeoleku vahel. Kuigi dilemmasid ei ole võimalik lõplikult lahendada, on lahendust võimalik lõputult täiustada. Ma väidan, et see, kuidas demokraatlikud ühiskonnad neid dilemmasid lahendavad, ei sõltu mitte demokraatlikust kultuurist või rahvale omasest tarkusest, vaid demokraatlike ühiskondade enamuste arusaamadest, mis omakorda sõltuvad eelkõige ajaloolisest kogemusest. Minu väitekirjas välja pakutud teoreetiline selgitus aitab mõista, miks Eesti ja Soome julgeolekuotsingud aastatel 1918–1948 läbi kukkusid ja miks Eesti ja Soome oma ajaloo pöördepunktides erinevaid valikuid tegid. Mõistetavaks muutub ka Eesti riigijuhtide käitumine 1939. ja 1940. aasta sündmuste ajal. Loodetavasti aitab minu väitekiri kaasa õiglase hinnangu andmisele Konstantin Pätsi ja Johan Laidoneri tegevusele ja Eesti ühiskonna lepitamisele küsimuses, kas tegemist oli kangelaste või kurjategijatega. Kõige tähtsam on siiski aidata kaasa mõistmisele, kuivõrd haprad võivad olla demokraatia ja julgeolek, kuidas nad vastastikku üksteisest sõltuvad ja eriti – kuidas nad sõltuvad ajaloolisest kogemusest. https://www.ester.ee/record=b5391015

The current thesis studies how the archaeological and folkloristic information relate to each other and what are the possibilities to use theses as a combined. Archaeological research has focused on the material remains from the past; the folklorists, however, study the information that has mainly been passed on orally. When the academic interest lies in the past culture as a whole, the use of different sources will grant richer and more comprehensive knowledge. The case-study of thesis that is covering the material from Estonia is analysing the information about origin of and finds associated with human remains in wetlands. The main focus has been on mires. This kind of intriguing and unstudied topic was chosen because of folk songs that describe burying in mires. Also, in the place-lore there are stories about burials in mires, as well as depictions of drowning in wetlands. For archaeologist, this raises a question, whether this folklore could reflect the events that have led to bog bodies? Additionally, the place-lore describes unearthing of human remains from waterlogged soil of which there is no archaeological documentation. Attempts to find new archaeological record for some of these place-lore sites were unfortunately unsuccessful. These fieldworks illustrate how complicated is it to discover archaeological finds from wetlands. At the same time, the work with archive sources and literature showed that there are previous archaeologically documented finds of human remains from wetlands. The age, context and way of emerge of these human remains has been very different. The archaeological excavation conducted as part of this research in Alasoo Varajemägi revealed finds in peat originating from the pyre. It seems that items left behind from cremation burials were taken into a former lake. There was no record of this kind of behaviour from the Viking Age previously documented in Estonia. Therefore, the study represents information in archaeology and folkloristics concerning human remains in wetlands. The information of both records is quite diverse, but the systematic study has brought them closer and at the same time has helped to understand the character how the archaeological and folkloristic information has been emerged, transmitted and stored. On täiesti loomulik, et erinevad minevikust pärinevad allikaliigid kannavad endas edasi erinevat informatsiooni. Käesolevas doktoritöös vaadeldakse, kuidas suhestuvad omavahel arheoloogiline ja rahvaluuleline teave ning millised on võimalused nende kooskasutuseks. Arheoloogide uurimistöö on keskendunud mineviku materiaalsetele jäänustele, rahvaluuleteadlased aga uurivad informatsiooni, mis on üle põlvkondade edasi kandunud enamasti suusõnaliselt. Kui teadlase uurimisobjektiks on mineviku kultuur terviklikult, siis aitab erinevate allikate kasutus saada möödunud aegadest palju rikkama ja mitmekihilisema arusaama. Eesti materjali käsitleva doktoritöö juhtumuuring vaatleb teavet inimjäänuste tekkest ja vastavatest leidudest märgaladel. Peamise tähelepanu all on olnud sood. Niisuguse intrigeeriva ja senikäsitlemata teemavaliku põhjustasid sohu matmisi kirjeldavad rahvalaulud. Ka kohapärimuses on nii jutte matmisest sohu kui ka kirjeldusi uppumistest märgaladel. Arheoloogi jaoks tõstatab see küsimuse, kas ja mil määral võib niisugune pärimus kajastada sündmusi, mis on maha jätnud soolaipu? Lisaks kirjeldab kohapärimus inimsäilmete avastamist liigniiskest pinnasest, mille kohta arheoloogilist dokumentatsiooni ei leidu. Katse leida osadest pärimuspaikadest uusi arheoloogilisi tõendeid kahjuks ei õnnestunud. Mainitud välitööd illustreerivad hästi, kui keerukas ja raske on avastada märgaladelt arheoloogiliste leide. Samas, töö arhiiviallikate ja kirjandusega näitas, et eelnevalt on ka arheoloogiliselt registreeritud inimjäänuste leide liigniiskest pinnasest. Need leiud on aga väga erineva vanuse, konteksti ja tekkepõhjusega. Doktoritöö raames tehtud arheoloogiliste kaevamistega õnnestus Alasoo Varajemäel tuvastada turbas asuvaid leide, mis pärinesid tuleriidalt. Näib, et põletusmatustest järele jäänud asju viidi endisaegsesse järvevette. Niisugusest viikingiaegsest käitumisest Eesti arheoloogias seni tõendeid ei olnud. Seega esitab uurimus märgaladel leiduvate inimjäänustega seonduvat arheoloogilist ja rahvaluulelist informatsiooni. Mõlemas allikaliigis esinev informatsioon on küll üsna eriilmeline, kuid süstemaatiline uurimine on vähendanud nende vahelist lõhet ja samas aidanud mõtestada ka eripära, kuidas need allikad on tekkinud, edasi kandunud ning talletunud.

Today, sheep husbandry forms a small, but important part in Estonian agriculture. By using zooarchaeological and genetic data, the aim of the dissertation is to study sheep husbandry and the development of maternal lineages in Estonia and more widely, in the Baltic Sea region, from the Middle Bronze Age (c. 1200 BC) until the present-day. The zooarchaeological part of the thesis focuses on animal consumption in Late Iron Age and medieval Viljandi and Karksi, and tackles the changes in proportion and exploitation of faunal resources over time. The genetic part of the research aims to analyse the maternally inherited mitochondrial DNA both in the ancient populations and modern Kihnu native sheep. The results of the study indicate that, starting from the Bronze Age, sheep husbandry and utilisation in Estonia has been rather persistent. Nonetheless, changes occurred, which could mainly be related to two distinct periods. Firstly, the transition from prehistory to the Middle Ages, including the 13th century Crusades. Genetically it is expressed in population expansion, possibly linked to the overall increase in human population and the demand for meat supplies. Moreover, the growth of the populations seems to have relied on local herds, while the effect of imported animals was probably insignificant. Secondly, changes came along with the beginning of the large-scale breeding in the 19th century, aimed to improve the local production of mutton and wool. With slightly decreased genetic diversity, the local sheep, including the Kihnu native sheep, have been preserved up to the present. Lammas (Ovis aries) on alates hilispronksiajast olnud üks enimkasvatatud kariloomi Eestis. Tänapäeval moodustab lambakasvatus Eestis väikese, kuid järjest olulisema osa põllumajandusest. Tuginedes zooarheoloogilisele leiuainesele ja geneetilisele andmestikule, on väitekirja eesmärk uurida lambakasvatust ning lammaste emaliinide ajalugu Eestis ja laiemalt Läänemere kultuuriruumis keskmisest pronksiajast (u 1200 eKr) tänapäevani. Töö zooarheoloogiline pool keskendub hilisrauaajale ja keskajale Viljandis ja Karksis ning loomsete saaduste tarbimisharjumustele ajas ja ruumis. Geneetiline osa analüüsib emaliini pidi pärandatavat mitokondriaalset DNA-d vanades lambaleidudes ja ka tänapäevastes Kihnu maalammastes. Uurimusest selgub, et lambakasvatus ja lammaste tarvitamine toiduks on Eestis olnud pronksiajast peale üsna järjepidev. Siiski ilmnevad mõned murranguajad, millele tuleb seletust otsida laiemal ajaloolisel taustal. Need muudatused seostuvad kahe perioodiga. Esiteks üleminek muinasajalt keskajale koos 13. sajandi alguse ristisõdadega. Geneetilises andmestikus väljendub see lambapopulatsiooni suurenemises, mis on toimunud kohaliku talumajanduse ja olemasolevate loomade baasil, ning mis võib olla tingitud sellest, et keskajal kasvas koos rahvaarvuga ka kariloomade hulk. Teine murrang ilmneb seoses suure tõuaretusega 19. sajandil, mil eeskätt Lääne-Euroopast sisse toodud tõugudega hakati kohalike lammaste liha- ja villatootlikkust parandama. Hoolimata sellest on algupärased põliste tunnustega maalambad, eeskätt Kihnu maalammas, säilinud tänapäevani, kuigi mõnevõrra väiksema geneetilise mitmekesisusega.
