  1. Keynote: Italian Musicologists and the Challenge of Music Pedagogy

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available The article offers an overview of the research and initiatives that have been carried out over the past 15 years by a group of Italian scholars in the field of Music Pedagogy. In Italy, but also in other European countries, musicological and pedagogic-didactic researches often appear to be pursued separately. On the one hand, Musicology has increasingly narrowed its focus on strictly discipline-related topics, while the development of Music Pedagogy and Music Didactics has mostly taken place outside of universities, with no connections to the so-called “learned knowledge” (or savoir savant of Musicology and Educational Science (General Pedagogy and Didactics. Therefore, while it is essential that musicologists build a specific scholarly knowledge that is solid and sound in all respects, what is equally essential is that this knowledge is channelled into the didactics of the discipline and utilized in school settings.

    Full Text Available This paper, which has been proposed as keynote speech at the study session “Transmission of musical knowledge: constructing a European citizenship” (Rome, XIX IMS conference, July 6, 2012, suggests that it is important, and useful (in terms of both education and politics for all citizens of the European Union, and for the foreigners who access the EU, to highlight the art music (Kunstmusik, musica d’arte heritage, which constitutes one of the peculiar, distinctive features of European culture, and whose importance cannot certainly be reduced to the sphere of entertainment.The art music heritage raises specific issues, first of all its composite nature. We have a material heritage, made of objects that require preservation (instruments, scores, treatises, documents, buildings designed for music performance; and we have an immaterial heritage – whose value can be aesthetic (works and events, i.e. music pieces to be performed or listened to or intellectual (music texts, writings on music, theoretical and practical knowledge, performance techniques. The latter can only survive if it is taken care of and transmitted.Knowledge of the European music heritage can be a powerful tool for integration in the building of a European citizenship, since it makes us aware that we have one common musical tradition, open and manifold. This provides a shared reference framework to the many local musical traditions scattered over the continent, and, at the same time, offers a reading key (by analogy and/or contrast to groups of non-European citizens who come from different music cultures and aim at integrating into the Union. In this process, musicologists can play a crucial role, if only they understand that one of the missions of their discipline is to educate and transmit musical culture. Music pedagogy and didactics are not separate fields - on the contrary, we must again look at them as a supporting branch, vigorous and thriving, attached to the trunk

    Full Text Available This essay presents the history and development of the The Estonian Folklore Archives, the central folklore archives of Estonia established in 1927, and examines its function in relation to the development of online databases. The Archives’ primary purpose has been to make the manuscript materials easily available for researchers working with the collection. The collections consist of manuscripts, sound recordings, photographs, and film and video materials, with an experimental multimedia collection as of 2008. The most extensive project related to the collections was the digitization in 2011-12 of Jakob Hurt’s folklore collection, stored in Kivike, a new file repository and archival infosystem of the Estonian Literary Museum.

    Full Text Available The paper analyses Estonian tax structure changes during the last decade and critically assesses the current situation. The country’s tax mix is rather unique among EU countries – it has one of the highest proportions of consumption taxes in total taxes and the lowest level of capital and profit taxes. Such an unbalanced tax structure creates risks for public finances, limits revenue collection and distorts the business environment.

  4. Estonian Jumal ‘God’

    Directory of Open Access Journals (Sweden)

    Karl Pajusalu

    2016-06-01

    Full Text Available The article focuses on semantics and the use of the word jumal ‘god’ in Estonian. At first, we give an overview of the etymology of jumal ‘god’ and its meanings in Standard Estonian and Estonian dialects. Then we examine jumal ‘god’ as a linguistic unit associated with different constructions and collocational patterns, bleaching of the meaning, and usage in fulfilling different communication goals. In our study we show how jumal ‘god’ can refer literally to the higher power of Christianity or some other religion but it is also used in the weakened, bleached sense, meaning ‘very, completely’ or ‘total, absolute’, and in combination with certain verbs, meaning ‘random’, ‘indefinite’.

    Full Text Available This article is a part of a wider research on Estonian folk dance, aiming to map the emergence of folk dance groups and to study the practices and role of folk dance among the Estonian diaspora. The article sets out to explore incentives contributing to intergenerational transmission of Estonian folk dance tradition. 54 interviews (21 men and 33 women aged 38 to 87 were carried out with Estonians living in Australia, Canada, Germany, Great Britain, Sweden and the United States. The analysis of the interviews is based on two research questions: 1 What incentives have guided Estonians’ folk dance activity in historical perspective from World War II until today? 2 What qualities originating in Estonian folk dance have motivated people to carry on Estonian folk dance practices? The principles of grounded theory were used in the analysis of interviews. The article discusses the results of two sets of analyses. Motivational changes in folk dance as a leisure pursuit have brought into focus three historical periods of folk dance transmission. Incentives originating from dance and dancing (self-expression, self-determination, cooperation, emotion, physical training and the external qualities accompanying dance and dancing (socialising, ‘Estonianness’, tradition are discussed in the context of continuity of Estonian folk dance tradition among the Estonian diaspora.

  16. Acquisition of motion in L2 Estonian

    Full Text Available This study focuses on the acquisition of Motion in Estonian by native English speakers. The aim was to determine how English learners of Estonian are influenced by their first language (L1 when describing Motion events in Estonian as their second language (L2. Prior studies have claimed that people develop certain ways of thinking for speaking when learning their first language which affect the acquisition of other languages (e.g. Slobin 1996, Pool, Pajusalu 2012 i.a.. In order to find out how native English speakers are influenced by their L1 when acquiring Motion in Estonian, an experiment was implemented on 22 participants (11 native English speakers and 11 native Estonian speakers in which they were asked to write a short narrative in Estonian based on a picture book by Mayer (1969. The Motion events found in the narratives were analysed one by one. The findings suggest that L1 thinking patterns influence the intermediate learners more than the advanced or beginner learners, thus partly supporting the findings of Cadierno and Ruiz (2006 who reached a similar conclusion.

  4. Digimodernistlik eesti kirjanik / The Digimodernist Estonian Writer

    Directory of Open Access Journals (Sweden)

    Piret Viires

    2013-06-01

    Full Text Available The article examines the cultural situation following postmodernism in the first decade of the 21st century. To characterise this situation, the umbrella term “post-postmodernism” is used, as well as “neomodernism”, “altermodern”, “metamodernism”, “hypermodernity”, “performatism”, “critical realism” etc. All these approaches are, in a wider sense, united by their aim of opposing postmodernist cynicism and irony, and bringing back truth, simplicity and clarity. It has also been found that literature has returned or is returning to realism, and various cultural phenomena are emerging, which have been designated by the concept “new sincerity”.In descriptions of the current cultural situation, this trend seeking truth and simplicity is supported by approaches which emphasise the significance of technological developments during the last decade. A prominent figure here is Alan Kirby, who launched the term “digimodernism”, mainly linked with the adaptation and spread of Web 2.0 at the beginning of the 21st century: the blogosphere, Wikipedia, Twitter and Facebook.The article seeks answers to the question of whether we can talk about digimodernism in Estonian literature in the 2000s. In the 1990s Estonian writers were quite reluctant to undertake computer-technological experiments, and there are only a few examples of Estonian digital literature, whereas a change occurred in the 2000s. Many Estonian writers have had and still have their own blogs and surprisingly many have joined Facebook. The term “twitterature” is also familiar to Estonian writers. The article tackles the dominant topics in the blogs of Estonian writers and analyses their possible collective creative work on Facebook. A question is raised as to whether it is possible that the fragmentary narrative structure of blogs and Facebook has influenced mainstream literature.The article concludes that one essential change in Estonian literature in the

    Asu, Eva Liina; Nolan, Francis

    2007-01-01

    In Estonian, as in a number of other languages, the nuclear pitch accent is often low and level. This paper presents two studies of this phenomenon. The first, a phonetic analysis of carefully structured read sentences shows that low accentuation can also spread to the prenuclear accents in an intonational phrase. The resulting sentence contours…

  11. Ethnic return migration: an Estonian case.

    Science.gov (United States)

    Kulu, H

    1998-01-01

    "This article examines return migration during the post World War 2 period of descendants of Estonians who emigrated to Russia at the end of the nineteenth and at the beginning of the twentieth century" The focus is on changing migration patterns over time. "The behavioural norm of Estonians born in the 1910s-1920s has been return migration to Estonia, while the migration behaviour of the 1930s-1940s and the 1950s-1960s generations can be characterized by urbanization in West Siberia. The results give reason to assume that ethnic return migration over a long period depends neither directly nor indirectly on momentary environmental changes, but rather on changes in people's values, habits, identity etc., which in the case of an ethnic minority living outside its historical homeland may be followed generation by generation."

  12. Estonian Middle Semantics with Evidence from Discourse

    Directory of Open Access Journals (Sweden)

    Virve-Anneli Vihman

    2004-01-01

    Full Text Available This paper presents arguments for recognizing a middle voice in Estonian. The claim that the semantics of middle-marked verbs differs in a substantial way from the semantics of other intransitive constructions leads to the examination of the discourse pragmatics of these constructions, and the relationship between discourse patterns and their valency and argument properties. Various topicality measures show that the argument participant in middle clauses lies between that of the sole participant (S in intransitive clauses and the O of active transitive clauses. The results regarding the discourse behaviour of middle arguments constitute new evidence for the view that middle constructions differ from ordinary intransitive verbs, despite structural similarities, and mark a unique range on the scale of transitivity exhibited by verbs in Estonian.

    This image shows a rare clear view of the South Pole (lower right) and the Ross Sea, Antarctica. The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) acquired the scene on December 26, 2001. The geographic South Pole is located in the center of Antarctica, at an altitude of 2,900 meters (9,300 feet). It rests on a continent-wide ice sheet that is 2,870 m thick, with the underlying bedrock only 30 m (98 feet) above sea level. The ice underlying the South Pole is as much as 140,000 years old, and is currently accumulating at about 82 cm (32 inches) per year. Roughly 2,500 km (1,550 miles) away is the green water of the Ross Sea, which indicates the presence of large numbers of phytoplankton. This is a highly productive part of the world's oceans. Also note the ice gathered around McMurdo Sound, seen toward the lefthand shoreline of the Ross Sea, at the edge of the Ross Ice Shelf. According to National Science Foundation researchers, this ice is making it difficult for penguins to reach their food supply. Separating the continental Antarctic ice sheet from the Ross Sea are the Queen Maud Mountains and the Ross Ice Shelf.

    The Estonian Biobank cohort is a volunteer-based sample of the Estonian resident adult population (aged ≥18 years). The current number of participants-close to 52000--represents a large proportion, 5%, of the Estonian adult population, making it ideally suited to population-based studies. General practitioners (GPs) and medical personnel in the special recruitment offices have recruited participants throughout the country. At baseline, the GPs performed a standardized health examination of the participants, who also donated blood samples for DNA, white blood cells and plasma tests and filled out a 16-module questionnaire on health-related topics such as lifestyle, diet and clinical diagnoses described in WHO ICD-10. A significant part of the cohort has whole genome sequencing (100), genome-wide single nucleotide polymorphism (SNP) array data (20 000) and/or NMR metabolome data (11 000) available (http://www.geenivaramu.ee/for-scientists/data-release/). The data are continuously updated through periodical linking to national electronic databases and registries. A part of the cohort has been re-contacted for follow-up purposes and resampling, and targeted invitations are possible for specific purposes, for example people with a specific diagnosis. The Estonian Genome Center of the University of Tartu is actively collaborating with many universities, research institutes and consortia and encourages fellow scientists worldwide to co-initiate new academic or industrial joint projects with us.

  3. Utilisation of Estonian energy wood resources

    Energy Technology Data Exchange (ETDEWEB)

    Muiste, P.; Tullus, H.; Uri, V. [Estonian Agricultural University, Tartu (Estonia)

    1996-12-31

    In the end of the Soviet period in the 1980s, a long-term energy programme for Estonia was worked out. The energy system was planned to be based on nuclear power and the share of domestic alternative sources of energy was low. The situation has greatly changed after the re-establishment of the Estonian independence, and now wood and peat fuels play an important role in the energy system. Energy consumption in Estonia decreased during the period 1970-1993, but this process has less influenced the consumption of domestic renewable fuels - peat and wood. It means that the share of these fuels has grown. The investment on substitution of imported fossil fuels and on conversion of boiler plants from fossil fuels to domestic fuels has reached the level of USD 100 million. The perspectives of the wood energy depend mainly on two factors; the resources and the price of wood energy compared with other fuels. The situation in wood market influences both the possible quantities and the price. It is typical that the quickly growing cost of labour power in Estonia is greatly affecting the price of energy wood. Though the price level of fuel peat and wood chips is lower than the world market price today, the conditions for using biofuels could be more favourable, if higher environmental fees were introduced. In conjunction with increasing utilisation of biofuels it is important to evaluate possible emissions or removal of greenhouse gases from Estonian forests 3 refs.

    It is widely accepted that the increase of greenhouse gas concentrations in the atmosphere due to human activities would result in warming of the Earth`s surface. To examine this effect and better understand how the GHG increase in the atmosphere might change the climate in the future, how ecosystems and societies in different regions of the World should adapt to these changes, what must policymakers do for the mitigation of that effect, the worldwide project within the Framework Convention on Climate Change was generated by the initiative of United Nations. Estonia is one of more than 150 countries, which signed the Framework Convention on Climate Change at the United Nations Conference on Environment and Development held in Rio de Janeiro in June 1992. In 1994 a new project, Estonian Country Study was initiated within the US Country Studies Program. The project will help to compile the GHG inventory for Estonia, find contemporary trends to investigate the impact of climate change on the Estonian ecosystems and economy and to formulate national strategies for Estonia addressing to global climate change.

  5. On Estonian Folk Culture: Pro et contra

    Directory of Open Access Journals (Sweden)

    Piret Õunapuu

    2014-08-01

    Full Text Available The year 2013 was designated the year of heritage in Estonia, with any kind of intangible and tangible heritage enjoying pride of place. Heritage was written and spoken about and revived in all kinds of ways and manners. The motto of the year was: There is no heritage without heir. Cultural heritage is a comprehensive concept. This article focuses, above all, on indigenous cultural heritage and, more precisely, its tangible (so-called object part. Was the Estonian peasant, 120 years back, with his gradually increasing self-confidence, proud or ashamed of his archaic household items? Rustic folk culture was highly viable at that time. In many places people still wore folk costumes – if not daily, then at least the older generation used to wear them to church. A great part of Estonians still lived as if in a museum. Actually, this reminded of the old times that people tried to put behind them, and sons were sent to school in town for a better and more civilised future. In the context of this article, the most important agency is peasants’ attitude towards tangible heritage – folk culture in the widest sense of the word. The appendix, Pro et contra, at the end of the article exemplifies this on the basis of different sources.

Node 1 will be the first Space Station hardware delivered by the Space Shuttle. He also disscusses the assembly sequence. The crew will conduct a series of rendezvous maneuvers similar to those conducted on other Shuttle missions to reach the orbiting FGB. Once the two elements are docked, Ross and Newman will conduct two scheduled spacewalks to connect power and data cables between the Node, PMAs and the FGB. The day following the spacewalks, Endeavour will undock from the two components, completing the first Space Station assembly mission.

    Phenolic compounds are semi-volatile organic compounds produced during biomass burning and lignin degradation in water. In atmospheric and paleoclimatic ice cores studies, these compounds are used as biomarkers of wood combustion and supply information on the type of combusted biomass. Phenolic compounds are therefore indicators of paleoclimatic interest. Recent studies of Antarctic aerosols highlighted that phenolic compounds in Antarctica are not exclusively attributable to biomass burning but also derive from marine sources. In order to study the marine contribution to aerosols we developed an analytical method to determine the concentration of vanillic acid, vanillin, p-coumaric acid, syringic acid, isovanillic acid, homovanillic acid, syringaldehyde, acetosyringone and acetovanillone present in dissolved and particle phases in Sea Ross waters using HPLC-MS/MS. The analytical method was validated and used to quantify phenolic compounds in 28 sea water samples collected during a 2012 Ross Sea R/V cruise. The observed compounds were vanillic acid, vanillin, acetovanillone and p-coumaric acid with concentrations in the ng/L range. Higher concentrations of analytes were present in the dissolved phase than in the particle phase. Sample concentrations were greatest in the coastal, surficial and less saline Ross Sea waters near Victoria Land.

    Mitochondrial DNA is a useful marker for population studies, human identification, and forensic analysis. Commonly used hypervariable regions I and II (HVI/HVII) were reported to contain as little as 25% of mitochondrial DNA variants and therefore the majority of power of discrimination of mitochondrial DNA resides in the coding region. Massively parallel sequencing technology enables entire mitochondrial genome sequencing. In this study, buccal swabs were collected from 114 unrelated Estonians and whole mitochondrial genome sequences were generated using the Illumina MiSeq system. The results are concordant with previous mtDNA control region reports of high haplogroup HV and U frequencies (47.4 and 23.7% in this study, respectively) in the Estonian population. One sample with the Northern Asian haplogroup D was detected. The genetic diversity of the Estonian population sample was estimated to be 99.67 and 95.85%, for mtGenome and HVI/HVII data, respectively. The random match probability for mtGenome data was 1.20 versus 4.99% for HVI/HVII. The nucleotide mean pairwise difference was 27 ± 11 for mtGenome and 7 ± 3 for HVI/HVII data. These data describe the genetic diversity of the Estonian population sample and emphasize the power of discrimination of the entire mitochondrial genome over the hypervariable regions.

  6. Estonian Political Parties in the mid-2010s

    Directory of Open Access Journals (Sweden)

    Lanko Dmitry

    2015-06-01

    Full Text Available The article provides an analysis of political party system of the Republic of Estonia in the mid-2010s. The analysis is based on the works of Moris Duverger. As one might expect, the establishment of proportionate electoral system in Estonia has resulted in the formation of a multi-party system, in which no single party dominates in the parliament even in a short run. The article demonstrates that though Estonian political party system develops in line with the tendencies typical to political party systems of most European countries, some of its elements are more common to postcommunist countries. It indicates that the political party system in Estonia has stabilized throughout the past decade. Today, five sixths of voters support one of the four main political parties. A minority of voters does not consider any of the four dominant parties as a representative of their interests; thus, they vote for parties that had not been previously represented in the parliament. This allowed for two minor political parties to pass into the parliament at 2015 elections: the Estonian Conservative People’s Party, and Free Party. In the long run the minor parties will be able to keep parliamentary seats depending on their ability to build coalitions, either with the three governing parties — Reform Party, Pro Patria and Republic Union, and Social-Democratic Party, or with opposition Centre Party. The article considers the impact of the split in the Estonian society between ethnic Estonians and Russophonic people on political party system. It demonstrates that the majority of Russophonic voters in Estonia support the Centre Party, every major political party in the country has its Russophonic voters, while Estonian United Left Party, which promotes itself as a particular representative of the country’s Russophonic minority, remains a marginal political force.

    2005-11-01

    The contents of nitrate, nitrite and N-nitrosoamines in commercial cured meat products on the Estonian market were determined for 2000-01 and 2003-04 as part of the Estonian food safety monitoring programme and the Estonian Science Foundation grant research activities. The maximum permitted levels of residual nitrites and nitrates were not exceeded in the samples analysed. However, a great variation in the content of nitrate, nitrite and N-nitrosoamines was found for all the products. The concentrations of these compounds in domestic cured meat products showed a decrease from year to year. The mean intake of nitrate, nitrite and N-nitrosoamines by Estonian children (n=346) from cured meat products was calculated on the basis of individual intake data. The mean daily intake of nitrates was 1.7 mg, that of nitrites was 0.83 mg and that of N-nitrosoamines was 0.073 microg. In the 2000-01 study, the calculated nitrite intake exceeded the acceptable daily intake by up to 140% for 1-6-year-old children and up to 105% in 2003-04.

    Evaluation of testicular measurements and daily sperm output (DSO) yields valuable information for predicting the reproductive capacity of stallions. The present study evaluated testicular measurements (height, length, width and circumference) and DSO of eight Tori and eight Estonian breed stallions. One ejaculate of semen was collected daily for 10 subsequent days from each stallion. The gel-free volume of semen was measured with a graduated glass cylinder and the sperm concentration was assessed with a Chorjajev chamber. The volume of gel-free fraction was multiplied by the sperm concentration to give the total number of spermatozoa (TSN). The DSO was calculated as mean TSN of collection on days 8-10 in Tori breed stallions and on days 4-10 in Estonian breed stallions. The DSO of Tori breed stallions was 12.9 x 109 spermatozoa and of Estonian breed stallions 4.5 x 109 spermatozoa (p Estonian breed stallions; right testis- height 7.4, length 10.6 and width 7.4 in Tori breed stallions, and 5.5, 7.4 and 5.3, respectively, in Estonian breed stallions. All these testicular measurements were significantly smaller in Estonian than in Tori breed stallions (p Estonian breed stallions, respectively (p Estonian (p Estonian breed stallions.

    Emission levels of selected trace metals from the Estonian oil shale fired power plant were studied. The plant is the largest single power plant in Estonia with an electricity production capacity of 1170 MWe (1995). Trace metals were sampled from the flue gases by a manual method incorporating...... a two-fraction particle sampling and subsequent absorption of the gaseous fraction. The analyses were principally performed with ICP-MS techniques. The trace metal contents of Estonian oil shale were found to be in the same order of magnitude as of coal on average. The high total particle concentrations...... in the flue gases of the studied oil shale plant contribute, however, to clearly higher total trace metal emission levels compared to modern coal fired power plants. Although the old electrostatic precipitators in the plant have been partly replaced by state-of-the-art electrostatic precipitators...

    Full Text Available The article reports the results of the study on the critical success factors and related information needs in Estonian industry conducted in 1999. Data were collected by interviews with 27 managers and engineers from 16 manufacturing companies in various industries. Most of the critical success factors taken up were related to marketing, information management, quality management, product development and technological innovations. The information needs of managers and engineers were related to competitors, customers, markets, technology, regulations, etc. Some identified CSFs expressed also priorities for development by Estonian economic authorities: to support the implementation of new technologies and introduction of quality management methods. The finding that information management was perceived as a very critical area supports the result of the recent Finnish study on CSFs.

  2. Remigration and Telling about It: Stories of Estonians from Russia

    Directory of Open Access Journals (Sweden)

    2008-08-01

    Full Text Available I will analyse the stories which focus on the reasons for returning toEstonia and remigration and have been written and told by Estonians who were born in Russia and returned to their motherland. These people returned to Estonia during 1941–1958 until the time Estonia became newly independent. Their ancestors had migrated to the rural areas of Russia since the middle of the 19th century.Stories about returning to homeland and adapting to the new environment have for a long time been limited to specific groups of people. They reached wider audiences after Estonia regained its independence and censorship weakened in Russia, and also as a result of the so-called biography boom in Eastern Europe. The context, time and situation of recording a narration or narrative shape the tales and can be repeatedly reassessed in the course of time.Stories about returning to homeland are both individual and collective; they express the experience of individuals as well as of a community or group. The stories of Estonians from certain regions are rather similar. The time and reasons for returning – forced or voluntary – have also had an impact on the stories.People do not mention shameful events in their lives or describe them only briefly. Even though this return of Estonians is not migration across state borders, most of these stories can still be classified as tales of traditional remigration. These stories give us information about the migration behaviour of remigrated Estonians and the emotions, attitudes and values associated with returning.

    Directory of Open Access Journals (Sweden)

    N. VASILIEV

    2008-12-01

    Full Text Available The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia’s transition to a market economy and during the accession period to the European Union (EU. The non-parametric method Data Envelopment Analysis (DEA was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000–2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU’s investment support schemes in new member states.;

  6. Revisiting the Estonian Cyber Attacks: Digital Threats and Multinational Responses

    Directory of Open Access Journals (Sweden)

    Stephen Herzog

    2011-01-01

    Full Text Available In April 2007, the Estonian Government moved a memorial commemorating the Soviet liberation of the country from the Nazis to a less prominent and visible location in Tallinn. This decision triggered rioting among Russian-speaking minorities and cyber terrorism targeting Estonia's critical economic and political infrastructure. Drawing upon the Estonian cyber attacks, this article argues that globalization and the Internet have enabled transnational groups—such as the Russian diaspora—to avenge their grievances by threatening the sovereignty of nation-states in cyberspace. Sophisticated and virtually untraceable political "hacktivists" may now possess the ability to disrupt or destroy government operations, banking transactions, city power grids, and even military weapon systems. Fortunately, western countries banded together to effectively combat the Estonian cyber attacks and minimize their effects. However, this article concludes that in the age of globalization, interdependence, and digital interconnectedness, nation-states must engage in increased cooperative cyber-defense activities to counter and prevent devastating Internet attacks and their implications.

    2004-10-01

    The surgical management of mitral valve disease in women of childbearing age, young patients, and children with congenital mitral valve defects is made difficult by the prospect of lifelong anticoagulation. We suggest the use of a pulmonary autograft in the mitral position (Ross II procedure) as an alternative surgical technique. We present a review of the literature, historical perspectives, indications, selection criteria, and surgical technique for the Ross II procedure. Our literature search identified 14 studies that reported results from the Ross II operation. Performed in 103 patients, the overall in-hospital mortality was 7 (6.7%), with a late mortality of 10 (9%). Although further research is needed, current evidence suggests the Ross II operation is a valuable alternative in low-risk young patients where valve durability and the complication rate from other procedures is unsatisfactory and anticoagulation not ideal.

  17. Western Ross Sea continental slope gravity currents

    Science.gov (United States)

    Gordon, Arnold L.; Orsi, Alejandro H.; Muench, Robin; Huber, Bruce A.; Zambianchi, Enrico; Visbeck, Martin

    2009-06-01

    Antarctic Bottom Water of the world ocean is derived from dense Shelf Water that is carried downslope by gravity currents at specific sites along the Antarctic margins. Data gathered by the AnSlope and CLIMA programs reveal the presence of energetic gravity currents that are formed over the western continental slope of the Ross Sea when High Salinity Shelf Water exits the shelf through Drygalski Trough. Joides Trough, immediately to the east, offers an additional escape route for less saline Shelf Water, while the Glomar Challenger Trough still farther east is a major pathway for export of the once supercooled low-salinity Ice Shelf Water that forms under the Ross Ice Shelf. The Drygalski Trough gravity currents increase in thickness from ˜100 to ˜400 m on proceeding downslope from ˜600 m (the shelf break) to 1200 m (upper slope) sea floor depth, while turning sharply to the west in response to the Coriolis force during their descent. The mean current pathway trends ˜35° downslope from isobaths. Benthic-layer current and thickness are correlated with the bottom water salinity, which exerts the primary control over the benthic-layer density. A 1-year time series of bottom-water current and hydrographic properties obtained on the slope near the 1000 m isobath indicates episodic pulses of Shelf Water export through Drygalski Trough. These cold (34.75) pulses correlate with strong downslope bottom flow. Extreme examples occurred during austral summer/fall 2003, comprising concentrated High Salinity Shelf Water (-1.9 °C; 34.79) and approaching 1.5 m s -1 at descent angles as large as ˜60° relative to the isobaths. Such events were most common during November-May, consistent with a northward shift in position of the dense Shelf Water during austral summer. The coldest, saltiest bottom water was measured from mid-April to mid-May 2003. The summer/fall export of High Salinity Shelf Water observed in 2004 was less than that seen in 2003. This difference, if real

    2012-01-01

    Full Text Available The varieties of the Estonian language outside Estonia, differing from standard Estonian spoken in Estonia, are regional and generally oral language variants, influenced by local factors and variable intergenerational use. Containing loans from the dominant language, the oral language of the older generation still retains features either redundant or marginal in the current Estonian language geographic area. The first written documents on expatriate Estonians date back to the 19th century, but it was only after the Republic of Estonia was established in 1918 that a wider interest was taken in compatriots living abroad. In 1928, the Expatriate Estonian Society (Välis-Eesti Ühing was founded and the Expatriate Estonian Congress (Välis-Eesti kongress started to be held every five years. After Estonia was annexed by the Soviet Union in 1940, the word väliseestlane ’expatriate Estonian’ was used only in connection with Estonians living outside the Soviet Union. In the 1950s and 1960s, linguists became specifically interested in the Estonian settlements of Caucasus, Siberia and Ussuriland. Scholars, hoping to find in Siberia or Caucasus the archaic language of former settlers still alive, discovered that vernacular Estonian was not influenced so much by archaisms (caused by separation from the homeland as influences from long-term contact with other languages.Since the late 1990s, the study of the varieties of Estonian used outside Estonia has taken a new direction. This can be recognised by the increased interest in the varieties of Estonian in various new countries of residence (e.g. Denmark, Finland, Germany. The focus of interest moving to western countries did not mean a loss of interest in the areas of the former Soviet empire. In 1996, the Centre for Migration and Diaspora Studies was set up in the Tartu University Institute of Geography. Presently, one of the prestigious research projects (2010−2013 of Finno-Ugric languages, the EU

  19. Climate variability and Ross River virus transmission.

    2002-08-01

    (1) To examine the feasibility to link climate data with monthly incidence of Ross River virus (RRv). (2) To assess the impact of climate variability on the RRv transmission. An ecological time series analysis was performed on the data collected between 1985 to 1996 in Queensland, Australia. Information on the notified RRv cases was obtained from the Queensland Department of Health. Climate and population data were supplied by the Australian Bureau of Meteorology and the Australian Bureau of Statistics, respectively. Spearman's rank correlation analyses were performed to examine the relation between climate variability and the monthly incidence of notified RRv infections. The autoregressive integrated moving average (ARIMA) model was used to perform a time series analysis. As maximum and minimum temperatures were highly correlated with each other (r(s)=0.75), two separate models were developed. For the eight major cities in Queensland, the climate-RRv correlation coefficients were in the range of 0.12 to 0.52 for maximum and minimum temperatures, -0.10 to 0.46 for rainfall, and 0.11 to 0.52 for relative humidity and high tide. For the whole State, rainfall (partial regression coefficient: 0.017 (95% confidence intervals 0.009 to 0.025) in Model I and 0.018 (0.010 to 0.026) in Model II), and high tidal level (0.030 (0.006 to 0.054) in Model I and 0.029 (0.005 to 0.053) in Model II) seemed to have played significant parts in the transmission of RRv in Queensland. Maximum temperature was also marginally significantly associated with the incidence of RRv infection. Rainfall, temperature, and tidal levels may be important environmental determinants in the transmission cycles of RRv disease.

    In support of the Department of Homeland Security / Science and Technology Directorate’s (DHS/S&T) creation of a new position called the Radiological Operations Support Specialist (ROSS), Lawrence Livermore National Laboratory (LLNL) in Sub-task 1.1 and 1.2 has assisted in the development of the ROSS skills, knowledge, and abilities (SKAs); identified potentially relevant training; cross-mapped the training to the SKAs; and identified gaps in the training related to the SKAs, as well as their respective level of training knowledge - current versus desired. In the follow on task, Sub-task 1.3, a 5 day ROSS Pilot Training course was developed to fill the priority gaps identified in Sub-Task 1.2. Additionally, in Sub-Task 1.5, LLNL has performed a gap analysis of electronic tools, handbooks, and job-aides currently available to the ROSS and developed recommendations for additional and next generation tools to ensure the operational effectiveness of the ROSS position. This document summarizes the feedback received from the instructors and pilot course observers on what worked in the course and what could be improved as well as an assessment of the Pre- and Post-Test administered to the students.

    2016-01-01

    Use of resorbable external reinforcement of the pulmonary autograft during the Ross operation has been suggested, but the differential regional potential for dilation of the aorta, mainly regarding the neo-root and the neo-Valsalva sinuses, represents an unresolved issue. Auxetic materials could be useful in preventing dilation given their favorable mechanical properties. We designed a composite semiresorbable armoured bioprosthesis constituted by polydioxanone and expanded polytetrafluoroethylene and evaluated its effectiveness as a pulmonary autograft reinforcement device in an animal model of the Ross procedure. An experimental model of the Ross procedure was performed in 20 three-month-old growing lambs. The pulmonary autograft was alternatively nonreinforced (control group n = 10) or reinforced with composite bioprosthesis (reinforced group n = 10). Animals were followed up during growth for 6 months by angiography and echocardiography. Specific stainings for extracellular matrix and immunohistochemistry for metalloproteinase-9 were performed. Reference aortic diameter increased from 14 ± 1 mm to 19 ± 2 mm over 6 months of growth. In the control group, pulmonary autograft distension (28 ± 2 mm) was immediately noted, followed by aneurysm development at 6 months (40 ± 2 mm, P < .001 vs reference). In the reinforced group, an initial dilation to 18 ± 1 mm was detected and the final diameter was 27 ± 2 mm (42% increase). Two deaths due to pulmonary autograft rupture occurred in the control group. On histology, the control group showed medial disruption with connective fibrous replacement, whereas in the reinforced group compensatory intimal hyperplasia was present in the absence of intimal tears. The bioprosthesis promoted a positive matrix rearrangement process favoring neoarterialization and elastic remodeling as demonstrated on specific staining for elastin collagen and metalloproteinase-9. The device adapted and functionally compensated for the

  3. Lower Ordovician Leetse Formation in the North Estonian Klint area

    Directory of Open Access Journals (Sweden)

    2006-06-01

    Full Text Available Sequences of the Leetse Formation were studied in order to find out the conodont biozonation, grain-size distribution, and glauconite mineral properties and their variations along the North Estonian Klint. On the basis of the conodont zonation of the Saka section, combined with earlier data, it was found that the Leetse Formation belongs to the Paroistodus proteus, Prioniodus elegans, and Oepikodus evae zones of various thickness and completeness along the North Estonian Klint. The Pr. elegans Zone of the Saka section was found to be remarkably complete and correlate well with equivalent intervals of sections in the St. Petersburg Region. Poorly lithified glauconitic sandstones of the Leetse Formation vary lithologically vertically as well as laterally. The Leetse Formation in the west has been repeatedly redeposited and is depleted in suspended fraction, while in the east it is more homogeneous and represents continuous shallow-water conditions. Glauconite is represented by a potassium-rich variety (about 9% K2O and most likely forms at least two discrete modifications. Laterally, glauconite of the Leetse Formation in the western part of the klint contains less K than that of the eastern part, indicating faster sedimentation. The d(001 value of glauconite diminishes upwards in the sequence, indicating acceleration of the sedimentation rate.

  4. Lithostratigraphy of Late Weichselian tills on the West Estonian Islands

    Directory of Open Access Journals (Sweden)

    Kadastik, E.

    1998-12-01

    Full Text Available Glacial stratigraphy of the West Estonian Islands comprises three different diamicton units which are correlated event-stratigraphically to the Pandivere and Palivere ice advances of the most recent (Late Weichselian glaciation and included into the Vörtsjärve Subformation according to Estonian stratigraphic nomenclature. A large number of till samples (1136 and drillcore sections (2500 were analysed in order to determine the genesis and composition of sediments from which the lithostratigraphical conclusions are derived. The two topmost diamictons are interpreted as genetic varieties of the Palivere Till - waterline melt-out and basal till. The Pandivere Till is the lowermost widespread till layer on the islands, which lies unconformably between the Palivere Till and carbonaceous bedrock. Lacustrine Köpu Sands separate the Palivere and Pandivere Tills in a few boreholes on the Köpu and Sörve Peninsulas. In deeply buried valleys on the Sörve Peninsula the Pandivere Till is underlain by lacustrine Viieristi Sands and greenish-grey compact till of unknown age. The correlatives of the Palivere and Pandivere Tills in southern Finland, south of Salpausselkä I (SSI, are thought to be the Espoo and Siuntio Tills, respectively.

  5. Russian-Estonian relations: a medium-term forecast

    Directory of Open Access Journals (Sweden)

    Lanko D. A.

    2014-03-01

    Full Text Available This article shows why the non-existent political dialogue between Russia and Estonia will hardly develop in the next five years and why Estonia can lose its significance for the Russian foreign policy rhetoric and Russian mass media. This conclusion is drawn from a medium-term forecast about the changing role of Estonia in Russian foreign policy. The forecast is based on the scenario methodology, which suggests that the modern means of political forecasting make it possible to make conclusions not about the future states of political phenomena, but rather about the trends of current states, which are called scenarios. The article describes the four possible scenarios of changes in the role of Estonia in Russian foreign policy that are evaluated from the perspective of the development of Russian-Estonian relations and factors affecting the probability of each scenario. It is shown that any change in the role of Estonia in Russian foreign policy depends not only on the specific actions of the Estonian elite, for example their readiness to change their position on the participation of Russian-speaking population in the democratic decision-making process or the evaluation of controversial events of the past, but also on the meaning that will be attached to these actions by the Russian elite.

  13. Morphological characteristics of pelves of estonian holstein and estonian native breed cows from the perspective of calving.

    Science.gov (United States)

    Nahkur, E; Ernits, E; Jalakas, M; Järv, E

    2011-10-01

    Dystocia is more common in Holstein-Friesian (HF) breed cows than in other dairy breeds. This is often caused by a disproportion between the birth canal of a female animal and the fetus. It is thought that the main determiners of unsuitability are the birth mass of the calf and the shape of the female pelvis. From the perspective of calving the cranial and caudal pelvic apertures are of great significance. This study focuses on pluriparous pelves of the Estonian Native Breed (EN) and the Estonian Holstein Breed (EHF). The longest measurement of the cranial pelvic aperture of an EHF cow is the conjugate diameter. The cranial pelvic aperture narrows slightly ventrally, being shaped like a trapezium with rounded angles. The longest measurement of the caudal aperture is its caudal transverse measurement. The aperture is flattened dorsoventrally. The cranial pelvic aperture of an EN cow is dorsally angular, but more oval ventrally, and is on the whole narrower and higher. By comparison with the EHF cow, the pelvic cavity of the EN cow widens caudally, and the height of the pelvic apertures contributes to ease of calving. It appears that the configuration of the pelvis of an EN cow is similar to the pelvis of the elk (Alces alces). The pelvis of the EHF cow has become unsuitable for easy calving, especially with regard to the caudal aperture.

  18. A Structural and Grammatical Analysis of the Estonian Constitution

    Directory of Open Access Journals (Sweden)

    Rull Addi

    2016-10-01

    Full Text Available The authors propose a novel quantitative method to analyse the structure of legal texts. The method enables to determine grammatical similarity between legal texts. The authors use the external theory of fundamental rights to separate the text of fundamental rights of the Estonian Constitution into two categories of norms: constitutional rights and restrictions. Grammatical similarity between constitutional rights, restrictions and selected legal acts and case law is measured. The layer of special norms renders the best grammatical similarity with the text of fundamental rights. The same grammatical similarity tests can be replicated to cover other jurisdictions in the future. The research is experimental, but the authors believe that the method can be utilised in fields of computational linguistics and legal text mining, but also in research where legal text structures are analysed for various purposes.

  19. A Comparison of the Referential Properties of Third Person Pronouns in Finnish and Estonian

    Directory of Open Access Journals (Sweden)

    Elsi Kaiser

    2004-01-01

    Full Text Available Abstract: This paper investigates the referential properties of third person anaphors in two closely related languages, Finnish and Estonian. Previous crosslinguistic research has shown that the most salient referents are referred to with the most reduced referring expressions. Moreover, factors such as (i grammatical role, (ii word order and (iii the main/subordinate clause distinction have been claimed to be correlated with referent salience. In this paper, we focus on how these factors influence the referential properties of the different members of the third person anaphoric paradigms in Finnish and Estonian. We use corpus evidence and native speaker survey data to investigate the referential properties of the Estonian forms and to compare them to the patterns observed for the Finnish pronoun hän ‘s/he’ and demonstrative tämä ‘this’ (see Kaiser, this volume; Kaiser 2000. Our preliminary results suggest that (i the Estonian short pronoun ta ‘s/he’ patterns like the Finnish pronoun hän ‘s/he’, in that they both prefer to refer to subjects, and (ii the Estonian demonstratives see/too ‘this/that’ resemble the Finnish demonstrative tämä ‘this,’ generally referring to non-subjects, postverbal NPs or subjects in subordinate clauses. Moreover, we find that the Estonian long pronominal form tema ‘s/he’ differs from the Finnish demonstrative tämä, despite their historical connection: As suggested by Pajusalu (1997, in Estonian, tema is used to refer to entities that contrast with something, whereas in Finnish tämä is used for entities low in salience (Kaiser, this volume. The implications of our findings for ‘accessibility hierarchy’-based approaches to reference resolution are also discussed.

    2008-12-01

    Full Text Available The article examines how folk calendar holidays are represented in Estonian fairy tales. It introduces some views presented in folklore studies about the concept of time in fairy tales and finds parallels with them in the Estonian context. The analysis relies on the digital corpus of Estonian fairy tales (5400 variants, created from the texts found in the Estonian Folklore Archives by the Fairy Tale Project of the Department of Estonian and Comparative Folklore, University of Tartu. Folk calendar holidays occur in Estonian fairy tales relatively seldom; most often these are holidays that occupy a significant place in the Estonian folk calendar (Christmas, St. John’s Day, Easter, St. George’s Day. Calendar holidays are notably mentioned more often in tale types which remain on the borderline between the fairy tale and the legend or the fairy tale and the religious tale. In Estonian fairy tales, calendar holidays are used on three levels of meaning: (1 the holiday is organically associated with the tale type; it has an essential role in the plot of the tale; (2 to a certain extent, the holiday could be replaced by another holiday having an analogous meaning; (3 the holiday forms an unimportant or occasional addition to the tale.

    2005-01-01

    The sea ice motion, area export, and deformation of the Ross Sea ice cover are examined with satellite passive microwave and RADARSAT observations. The record of high-resolution synthetic aperture radar (SAR) data, from 1998 and 2000, allows the estimation of the variability of ice deformation at the small scale (10 km) and to assess the quality of the longer record of passive microwave ice motion. Daily and subdaily deformation fields and RADARSAT imagery highlight the variability of motion and deformation in the Ross Sea. With the passive microwave ice motion, the area export at a flux gate positioned between Cape Adare and Land Bay is estimated. Between 1992 and 2003, a positive trend can be seen in the winter (March-November) ice area flux that has a mean of 990 x 103 km2 and ranges from a low of 600 x 103 km2 in 1992 to a peak of 1600 x 103 km2 in 2001. In the mean, the southern Ross Sea produces almost twice its own area of sea ice during the winter. Cross-gate sea level pressure (SLP) gradients explain 60% of the variance in the ice area flux. A positive trend in this gradient, from reanalysis products, suggests a 'spinup' of the Ross Sea Gyre over the past 12 yr. In both the NCEP-NCAR and ERA-40 surface pressure fields, longer-term trends in this gradient and mean SLP between 1979 and 2002 are explored along with positive anomalies in the monthly cross-gate SLP gradient associated with the positive phase of the Southern Hemisphere annular mode and the extrapolar Southern Oscillation.

  10. On the System of Place Name Signs in Estonian Sign Language

    Directory of Open Access Journals (Sweden)

    Liina Paales

    2010-12-01

    Full Text Available A place name sign is a linguistic-cultural marker that includes both memory and landscape. The author regards toponymic signs in Estonian Sign Language as representations of images held by the Estonian Deaf community: they reflect the geographical place, the period, the relationships of the Deaf community with hearing community, and the common and distinguishing features of the two cultures perceived by community's members. Name signs represent an element of signlore, which includes various types of creative linguistic play. There are stories hidden behind the place name signs that reveal the etymological origin of place name signs and reflect the community's memory. The purpose of this article is twofold. Firstly, it aims to introduce Estonian place name signs as Deaf signlore forms, analyse their structure and specify the main formation methods. Secondly, it interprets place-denoting signs in the light of understanding the foundations of Estonian Sign Language, Estonian Deaf education and education history, the traditions of local Deaf communities, and also of the cultural and local traditions of the dominant hearing communities. Both perspectives - linguistic and folkloristic - are represented in the current article.

    Bergamasco, A.; Defendi, V.; Spezie, G.; Budillon, G.; Carniel, S.

    In the framework of the CLIMA Project of the Italian National Program for Research in Antarctica, three different experimental data sets were acquired along the continental shelf break; two of them (in 1997 and 2001) close to Cape Adare, the 1998 one in the middle of the Ross Sea (i.e. 75 S, 177 W). The investigations were chosen in order to explore the downslope flow of the bottom waters produced in the Ross Sea, namely the High Salinity Shelf Water (HSSW, the densest water mass of the southern ocean coming from its formation site in the polynya region in Terra Nova bay), and the Ice Shelf Water (ISW, originated below the Ross Ice Shelf and outflowing northward). Both bottom waters spill over the shelf edge and mix with the Circumpolar Deep Water (CDW) contributing to the formation of the Antarctic Bottom Waters (AABW). Interpreting temperature, salinity and density maps in terms of cascading processes, both HSSW and ISW overflows are evidenced during, respectively, 1997 and 1998. During the 2001 acquisition there is no presence of HSSW along the shelf break, nevertheless distribution captures the evidence of a downslope flow process.

    2003-10-01

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

    The Antarctic Ross Sea is one of the key regions for polar research activities. Research stations from several countries located at the coast are the base for inland expeditions. Even in the austral summer, the Ross Sea is party covered with drifting ice fields; this requires an icebreaker for all marine explorations. Therefore, large geophysical surveys in the Ross Sea are difficult. But the area is of special interest for seismologists: The Terror Rift in the western Ross Sea is a prominent neotectonic structure of the West Antarctic Rift System (WARS). It is located near the coast in the Victoria Land Basin and extends parallel to the Transantarctic Mountains. The rifting processes and the accompanying active onshore volcanism lead to increased seismicity in the region. The annual waxing and waning of the sea-ice and the dynamics of the large Ross Ice Shelf and nearby glaciers generate additional seismic signals. Investigation on seismological activities associated with the WARS and the cryogenic signals simultaneously would give us an unprecedented opportunity to have a better understanding of the Evolution of the WARS (EWARS) and the rapid change in the cryospheric environment nearby. The Korea Polar Research Institute (KOPRI) and the Alfred-Wegener-Institut (AWI) have conducted a pilot study off the Korean Jang Bogo research station in the Terra Nova Bay by developing a collaborative research program (EWARS) since 2011 to explore seismicity and seismic noise in this region. Four broadband ocean-bottom seismometers (OBS) from the German DEPAS pool were deployed in January 2012 with the Korean research icebreaker RV Araon. Three instruments could successfully be recovered after 13 months, the fourth OBS was not accessible due to local sea-ice coverage. We have successfully completed a second recovery operation in January 2014. All stations recorded data of good quality, one station stopped after 8 months due to a recorder error. The OBS recovered in 2014

    The Ross Ice Shelf (RIS) is one of three gateways through which change in the ocean can be propagated into the interior of West Antarctica. Both the geologic record and ice sheet models indicate that it has experienced widespread retreat under past warm climates. But inland of the continental shelf, there are limited data available to validate the models. Understanding what controls the rate at which the ice shelf will respond to future climate change is central to making useful climate projections. Determining the retreat rate at the end of the last glacial maximum is one part of this challenge. In November 2015, four lines of multi-channel seismic data, totalling over 45 km, were collected on the Ross Ice Shelf, approximately 300 km south of Ross Island using a thumper seismic source and a 96 channel snow streamer. The seismic survey was undertaken under the New Zealand Antarctic Research Institute (NZARI) funded Aotearoa New Zealand Ross Ice Shelf Programme to resolve bathymetric details and to image sea floor sediments under a proposed drilling site on the ice shelf, at about 80.7 S and 174 E. The thumper, a purpose-built, trailer mounted, weight-drop seismic source was towed behind a Hägglund tracked vehicle to image the bathymetry and sediments underneath the RIS. Seismic data collection on an ice shelf has unique challenges, in particular strong attenuation of the seismic energy by snow and firn, and complex multiple ray paths. The thumper, which consists of a heavy weight (250kg) that is dropped on a large, ski mounted steel plate, produced a consistent, repeatable higher energy signal when compared to sledge hammer source and allowed for a greater geographic coverage and lower environmental impact than an explosive source survey. Our survey revealed that the seafloor is smooth and that there may be up to 100 m of layered sediments beneath the seafloor and possibly deeper, more complex structures.

    Spaceborne radar and lidar observations from the CloudSat and CALIPSO satellites are used to compare seasonal variations in the microphysical and radiative properties of clouds over Ross Island, Antarctica, with two contrasting Arctic atmospheric observatories located in Barrow, Alaska, and Summit, Greenland. At Ross Island, downstream from recurrent intrusions of marine air over the West Antarctic Ice Sheet and eastern Ross Ice Shelf, clouds exhibit a tendency toward the greatest geometrical thickness and coldest temperatures in summer, the largest average ice water content, IWC, at low altitude during summer and autumn, the most abundant IWC at cold mixed-phase temperatures (-40°C

    Full Text Available The Estonian National Museum (ENM, established in 1909 in Tartu,developed quickly and comprised a large membership in the country – the members living in Tallinn were active in heritage collection and awareness-raising activities, and formed a separate department which gradually gained independence. As an inevitable outcome, the Tallinn Department finally separated from the parent museum. Despite organisational difficulties and political circumstances, the department managed to supplement collections and arrange spectacular events. In 1919, the Tallinn Department of the ENM became an independent Estonian Museum Society in Tallinn, i.e. the Estonian Museum in Tallinn, which, in the course of time, became more inclined toward art and developed into the Art Museum of Estonia.

    The objective of this study was to estimate heritabilities and repeatabilities for milk coagulation traits [milk coagulation time (RCT) and curd firmness (E(30))] and genetic and phenotypic correlations between milk yield and composition traits (milk fat percentage and protein percentage, urea, somatic cell count, pH) in first-lactation Estonian Holstein dairy cattle. A total of 17,577 test-day records from 4,191 Estonian Holstein cows in 73 herds across the country were collected during routine milk recordings. Measurements of RCT and E(30) determined with the Optigraph (Ysebaert, Frepillon, France) are based on an optical signal in the near-infrared region. The cows had at least 3 measurements taken during the period from April 2005 to January 2009. Data were analyzed using a repeatability animal model. There was substantial variation in milk coagulation traits with a coefficient of variation of 27% for E(30) and 9% for the log-transformed RCT. The percentage of variation explained by herd was 3% for E(30) and 4% for RCT, suggesting that milk coagulation traits are not strongly affected by herd conditions (e.g., feeding). Heritability was 0.28 for RCT and 0.41 for E(30), and repeatability estimates were 0.45 and 0.50, respectively. Genetic correlation between both milk coagulation traits was negligible, suggesting that RCT and E(30) have genetically different foundations. Milk coagulation time had a moderately high positive genetic (0.69) and phenotypic (0.61) correlation with milk pH indicating that a high pH is related to a less favorable RCT. Curd firmness had a moderate positive genetic (0.48) and phenotypic (0.45) correlation with the protein percentage. Therefore, a high protein percentage is associated with favorable curd firmness. All reported genetic parameters were statistically significantly different from zero. Additional univariate random regression analysis for milk coagulation traits yielded slightly higher average heritabilities of 0.38 and 0

    Full Text Available The article analyses tale type The Woman as Wolf, which is one of the most popular folk tales in the Estonian Folklore Archives and is represented there both in the form of a fairy tale and in the form of a legend. The vast majority of the versions of The Woman as Wolf were written down in the first part of the 20th century within Estonia and where recorded from Estonians. The article introduces the content of the tale, the origin of the first records from the early 19th century, and the dissemination area of the tale, which remains outside Western Europe: apart from the Estonian versions there are Sami, Karelian, Vepsian, Livonian, Latvian, Lithuanian, Russian, Ukrainian and Belarusian versions. While in almost all the Estonian versions the main protagonist is transformed into a wolf, in most of the versions written down in other areas and ethnic groups, another animal or bird replaces the wolf. The author is of the opinion that the Finnic area is central to the distribution of the folk tale The Woman as Wolf. The animal the woman is transformed into in the plot would not have been a wolf in earlier times. The article provides an explanation why the wolf is predominant in Estonian written sources. For that purpose the ways in which the wolf and werewolf were perceived in earlier Estonian folk belief are introduced. At the end of the article interpretation of the folk tale is provided. The author states that the plot and some of the motifs found in this folk tale reflect the difficulties women had in submitting to the norms and values of patriarchal order within their society.

  20. History of experimental psychology from an Estonian perspective.

    Science.gov (United States)

    Allik, Jüri

    2007-11-01

    A short review of the development of experimental psychology from an Estonian perspective is presented. The first rector after the reopening of the University of Dorpat (Tartu) in 1802, Georg Friedrich Parrot (1767-1852) was interested in optical phenomena which he attempted to explain by introducing the concept of unconscious inferences, anticipating a similar theory proposed by Herman von Helmholtz 20 years later. One of the next rectors, Alfred Wilhelm Volkmann (1800-1878) was regarded by Edwin Boring as one of the founding fathers of the experimental psychology. Georg Wilhelm Struve (1793-1864) played an essential part in solving the problem of personal equations. Arthur Joachim von Oettingen (1836-1920) developed a theory of music harmony, which stimulated his student Wilhelm Friedrich Ostwald (1853-1932) to study colour harmony. Emil Kraepelin (1856-1926), the founder of modern psychiatry, is by far the most important experimental psychologist who has worked in Estonia. His successor Wladimir von Tchisch (1855-1922), another student of Wilhelm Wundt, continued Kraepelin's work in experimental psychology. The lives of Wolfgang Köhler (1887-1967), who was born in Reval (Tallinn), and Oswald Külpe (1862-1915), who graduated from the University of Dorpat, extended the link between the history of experimental psychology and Estonia. Karl Gustav Girgensohn (1875-1925), the founder of the Dorpat School of the psychology of religion, stretched the use of experimental methods to the study of religious experience.

  1. Art Deco in Estonian and Latvian Graphic Design Journals

    Directory of Open Access Journals (Sweden)

    Merle Talvik

    2005-10-01

    Full Text Available Years of the first independence in Estonia and Latvia involved the second wave of nationalism in art and culture. National theme became a source which had to be treated fashionably. The fashionable European style was art deco that spread in the Baltics, Finland and elsewhere in periphery of Europe from the second half of the 1920s until 1940. The author has examined and analysed a wide variety of Estonian illustrated magazines and journals. The examples of Latvian magazines come from the collections of the Information Centre of Art Academy of Latvia. The article explores common features in the pieces of the following artists: Vabbe – Vidbergs, Vaino – Apsītis, Madernieks – Reindorff, also Luhtein, Siirak, Mugasto, Verny, Triik versus Strunke, Zeberiņš and Kasparsons. The first goal is to prove that graphic design journals in art deco style were very popular in the periphery of Europe in these years. Secondly, the author claims that objects that apparently lie outside the definition of ‘art’ can be subjected to visual analysis in such a way as to open important doors to the understanding of their origin, reception, place in society, and subsequent history. They are reflections of relations of power, aesthetic objectives, changing theories and rituals of art and society. This is the reason why graphic design journals are treated as carriers of culture.

    The Estonian Biobank and several other biobanks established over a decade ago are now starting to yield valuable longitudinal follow-up data for large numbers of individuals. These samples have been used in hundreds of different genome-wide association studies, resulting in the identification of reliable disease-associated variants. The focus of genomic research has started to shift from identifying genetic and nongenetic risk factors associated with common complex diseases to understanding the underlying mechanisms of the diseases and suggesting novel targets for therapy. However, translation of findings from genomic research into medical practice is still lagging, mainly due to insufficient evidence of clinical validity and utility. In this review, we examine the different elements required for the implementation of personalized medicine based on genomic information. First, biobanks and genome centres are required and have been established for the high-throughput genomic screening of large numbers of samples. Secondly, the combination of susceptibility alleles into polygenic risk scores has improved risk prediction of cardiovascular disease, breast cancer and several other diseases. Finally, national health information systems are being developed internationally, to combine data from electronic medical records from different sources, and also to gradually incorporate genomic information. We focus on the experience in Estonia, one of several countries with national goals towards more personalized health care based on genomic information, where the unique combination of elements required to accomplish this goal are already in place.

    2016-06-01

    Full Text Available A theoretical model was developed to model the fate of two common pharmaceutical residues: diclofenac and ibuprofen in eight Estonian seaside cities that discharge their wastewaters directly into the Baltic Sea. The consumption rates of the active ingredients of diclofenac and ibuprofen from 2006-2014 were analysed. A decrease of 19.9% for diclofenac consumption and an increase of 14.1% for ibuprofen were found. The fate of diclofenac and ibuprofen were modelled by considering the human metabolism removal rate for pharmaceuticals, the removal rate of diclofenac and ibuprofen in activated sludge wastewater treatment plants (WWTP and annual flow rates. An average decrease from 1 to 0.8 µg/l (decrease of 20% for diclofenac and an increase from 11.4 to 13.4 µg/l (increase of 14.9% for ibuprofen for the concentration in the effluents of the WWTP were modelled. The model gives us a good overview about the theoretical concentrations of pharmaceutical residues in the environment and is helpful for evaluating environmental impacts.

Earlier the most important connections were to Sweden and Germany, but during Estonia’s new independence era, volumes to this alternative direction have increased considerably, and are continuously growing (time alone is good proxy for growth. This cannot be said for transport flows to Sweden, and Germany also holds high uncertainty. Based on the findings of this research, it is argued that Estonian connection growth was caused by different factors. One important factor was European Union membership in the year 2004. It should be emphasized that this was step-wise and was realized a decade ago. The main influence is that of the development of bulky trade. As measured in weight, both export and import of Finland with Estonia was found to be significant. However, in monetary terms only Finnish imports from Estonia was statistically significant. Finnish exports in turn to Estonia in value terms have contributed a negative effect (or even being insignificant. As the regression model was expanded, taking into account all three Baltic States and Poland, reliable additional findings couldn’t be drawn. Completed regression analysis shows that the explanation power of GDP based models became much lower after the years 2005‒2006.

    The analysis of some high-resolution hydrological data sets acquired during the 1997, 1998, 2001 and 2003 austral summers across the Ross Sea continental shelf break are here presented. The main focus of these cruises carried out in the framework of the Italian National Antarctic Program was the investigation of the downslope flow of the dense waters originated inside the Ross Sea. Such dense waters, flow near the bottom and, reaching the continental shelf break, ventilate the deep ocean. Two Antarctic continental shelf mechanisms can originate dense and deep waters. The former mechanism involves the formation, along the Victoria Land coasts, of a dense and saline water mass, the High Salinity Shelf Water (HSSW). The HSSW formation is linked to the rejection of salt into the water column as sea ice freezes, especially during winter, in the polynya areas, where the ice is continuously pushed offshore by the strong katabatic winds. The latter one is responsible of the formation of a supercold water mass, the Ice Shelf Water (ISW). The salt supplied by the HSSW recirculated below the Ross Ice Shelf, the latent heat of melting and the heat sink provided by the Ross Ice Shelf give rise to plumes of ISW, characterized by temperatures below the sea-surface freezing point. The dense shelf waters migrate to the continental shelf-break, spill over the shelf edge and descend the continental slope as a shelf-break gravity current, subject to friction and possibly enhanced by topographic channelling. Friction, in particular, breaks the constraint of potential vorticity conservation, counteracting the geostrophic tendency for along slope flow. The density-driven downslope motion or cascading entrains ambient water, namely the lower layer of the CDW, reaches a depth where density is the same and spreads off-slope. In fact, the cascading event is inhibited by friction without entrainment. The downslope processes are important for the ocean and climate system because they play a

    While case law in cases of wrongful conception, wrongful birth and wrongful life is completely missing in Estonia, this article is aimed at providing possible solutions under Estonian law to some of the legally complex problems that these cases contain. Through the analysis of Estonian, German and U.S. legal literature and case law, the article is mainly focused on proposing some solutions to the legal problems concerning compensable damage, but also explains the Estonian legal framework of the contractual and delictual basis for compensation for the damages. The application of several grounds for the possibility of limiting the compensation in the afore-mentioned cases are analysed.

    Full Text Available In a regionally heterogeneous country like Estonia, it is a difficult task to create a local government revenue structure that guarantees even supply of public services across the entire country and, at the same time, revenue autonomy for the municipalities. In the theoretical part of the current article the suitability of different sources of own revenues are analysed in the context of Estonian municipalities. The empirical part of the article compares the financing principles of Estonian municipalities with other EU countries. Finally, the proportions of different own sources of revenues in the budgets of Estonian local governments are examined and suggestions are made for changing the current system

    Cryptoendolithic microbial communities in the Ross Desert (McMurdo Dry Valleys) are characterized on the basis of photosynthetic microorganisms and fungi. Two eukaryotic communities (the lichen-dominated and Hemichloris communities) and three cyanobacterial communities (the red Gloeocapsa, Hormathonema-Gloeocapsa, and Chroococcidiopsis communities) are described. Eleven coccoid, one pleurocapsoid, and five filamentous cyanobacteria occurring in these communities are characterized and illustrated. The moisture grade of the rock substrate seems to affect pH, formation of primary iron stain, and the distribution of microbial communities.

    In the eighteenth century England was dominant in building telescopes and instrumentation. This paper describes the contributions of the most important opticians and telescope builders, from Newton’s Opticks and the telescope design that bears his name, through various instrument makers who constructed ‘popular’ telescopes and published descriptions of mirror grinding (Smith, the Dollonds and their patent on achromatic lenses), to Herschel, who refined the description of his polishing procedures, and Lord Rosse, who attempted to communicate his through publication. The narrative of theory, practice and communication takes unexpected turns.

    Full Text Available The article deals with the development in Russian-Estonian relations during the crises of 2007 and 2014, taking into consideration the balance between political and economic factors in the decision-making by Estonian government. A number of special aspects, trends and problems in trade and investment ties are detected. The aim of the study is to uncover key motivation behind the actions of both Russia and Estonia, to identify the drivers for economic and political development in the region, and to work out recommendations to adjust them. The questions put forward by the authors of this article could not be more topical at the time, when Russian economic situation is obviously getting worse and capital flight (to the neighboring EU Member States is likely to increase. The method of the study is comparative analysis of the impact on economic ties made by Russian-Estonian crisis of 2007 and the current international tension around Ukraine. The regional fossil fuel market and the possibilities of Gazprom involvement in its development are also analyzed. It is concluded that political motives are still important for Estonian decisionmaking, though they are balanced out by measures of business support (despite some of these measures being taken by the EU bodies. The role of political factor for the Russian side is increasing. It is acknowledged that there is a growing number of missed economic opportunities in the Russian Northwest.

    Full Text Available According to basic religious-phenomenological principles a supreme beingresides in heaven or is the heaven, an omnipotent creator, who is often as-signed the function of thunder, is called either Father or Grandfather, is sac-rificed the primal offering, and has turned into deus otiosus.Comparative linguistics has revealed that the earliest conception of a Balto-Finnic and Estonian supreme god dates back to the Finno-Volgaic etymologi-cal stratum, to the Neolithic period (3rd millennium BC, in archaeologicalterms. This is evidenced by the Estonian word juma(l ‘god’, which had for-merly signified heaven, but also the Indo-European loan taevas ‘heaven’ inthe Estonian language. The divergence of the con-ception of thunder god Ukuor Ukko apparently took place in the 1st mil-lennium BC; this is also indi-cated by archaeological data. According to the 13th-century Henrici ChroniconLivoniae and other chronicles the thun-der god of the coastal Estonians hasalso been called Taara or Tooru, which may be a derivation of the OldScandinavian Thor.

  1. Unemployment hysteresis in the “Nordic Kitten”: Evidence from five Estonian regions

    Directory of Open Access Journals (Sweden)

    Furuoka Fumitaka

    2015-01-01

    Full Text Available Unemployment hysteresis is a much discussed and researched topic in macroeconomics. The present paper examined unemployment hysteresis in five Estonian regions. It used two panel data methods, namely, the Im-Pesaran-Shin (IPS test and the Fourier Im-Pesaran-Shin (FIPS test. The originality and value of this paper is that this is the first study that uses the panel unit root tests to examine unemployment dynamics in the Estonian regions. The findings revealed that the unemployment rates in the Estonian regions could be best described as a stationary process. This result is in line with the natural rate hypothesis. A research implication is that this study has illustrated that nonlinear tests could be an appropriate approach to examine unemployment hysteresis because other methods may fail to reject the null hypothesis. A practical implication of this study is that it sheds light on the nature of unemployment dynamics in Estonia at the regional level. As the findings revealed, the unemployment rates in the Estonian regions had the meanreversion property. Therefore, the higher-than-normal unemployment rates are likely to return to the natural level even in the absence of intervention policies initiated by the government or policy makers.

    Full Text Available The Artotrogidae, one of the most primitive of siphonostomatoid families, consists currently of 117 species in 21 genera. Most of these species (65% are poorly or incompletely described since they have been rarely recorded in recent decades and, when encountered, have been found in very low numbers. During the 19th Italian Antarctic Expedition, with the RV Italica, to the Ross Sea in austral summer 2004, some artotrogid copepods were collected. This paper redescribes two species of artotrogid copepods, which are known only from the Southern Ocean, Neobradypontius neglectus and Cryptopontius latus, and describes for the first time a male of the genus Neobradypontius. Furthermore, a new species is described and added to Sestropontius, increasing the number of known species of this genus to three. The main discrepancies between the original descriptions and the specimens of the two species collected from the Ross Sea redescribed here were on the armature of the antennary exopod and leg 5. The new species, Sestropontius italicae, shares with its most similar congener, S. mckinnoni, the armature of the third endopodal segment of leg 1 and leg 2 and that of the third exopodal segment of leg 4. However, the segmentation of the antennae and the armature on the antennary exopod are different.

    The continental shelf of the Ross Sea exhibits substantial variations in physical forcing, ice cover, and biological processes on a variety of time and space scales. Its circulation is characterized by advective inputs from the east and exchanges with off-shelf regions via the troughs along the northern portions. Phytoplankton biomass is greater there than anywhere else in the Antarctic, although nitrate is rarely reduced to levels below 10 μmol L(-1). Overall growth is regulated by irradiance (via ice at the surface and by the depths of the mixed layers) and iron concentrations. Apex predators reach exceptional abundances, and the world's largest colonies of Adélie and emperor penguins are found there. Krill are represented by two species (Euphausia superba near the shelf break and Euphausia crystallorophias throughout the continental shelf region). Equally important and poorly known is the Antarctic silverfish (Pleuragramma antarcticum), which is also consumed by most upper-trophic-level predators. Future changes in the Ross Sea environment will have profound and unpredictable effects on the food web.

    In present study we describe the sequencing and annotated analysis of the individual genome of Estonian. Using SOLID technology we generated 2,449,441,916 of 50-bp reads. The Bioscope version 1.3 was used for mapping and pairing of reads to the NCBI human genome reference (build 36, hg18). Bioscope enables also the annotation of the results of variant (tertiary) analysis. The average mapping of reads was 75.5% with total coverage of 107.72 Gb. resulting in mean fold coverage of 34.6. We found 3,482,975 SNPs out of which 352,492 were novel. 21,222 SNPs were in coding region: 10,649 were synonymous SNPs, 10,360 were nonsynonymous missense SNPs, 155 were nonsynonymous nonsense SNPs and 58 were nonsynonymous frameshifts. We identified 219 CNVs with total base pair coverage of 37,326,300 bp and 87,451 large insertion/deletion polymorphisms covering 10,152,256 bp of the genome. In addition, we found 285,864 small size insertion/deletion polymorphisms out of which 133,969 were novel. Finally, we identified 53 inversions, 19 overlapped genes and 2 overlapped exons. Interestingly, we found the region in chromosome 6 to be enriched with the coding SNPs and CNVs. This study confirms previous findings, that our genomes are more complex and variable as thought before. Therefore, sequencing of the personal genomes followed by annotation would improve the analysis of heritability of phenotypes and our understandings on the functions of genome.

    Estonia is the only country in Europe with significant environmentally intensive oil shale-based energy production. However, the legal obligations of the EU will make substantial changes over the coming years to current electricity production technology. Increasing the use of alternative energy carriers for responding to future requirements has also been in focus. In this study, three different future electricity supply scenarios for Estonia in 2020 are considered and compared to the situation in 2002. They are based on domestic oil shale, imported natural gas, and imported nuclear power. According to the aims of the national energy policy, renewable energy sources were raised to 10% in all scenarios. Using the LCA methodology, the least damaging impact on the environment occurs in the 'nuclear scenario', with nuclear energy as the main energy source. The best scenario, however, depends on the weight or acceptance of accidental releases or other impacts not defined in this context. The 'Oil shale scenario' would be a slightly more damaging alternative than the 'Natural gas scenario' even if new technical solutions will remarkably improve the environmental performance of oil shale electricity production. Land use and waste disposal are crucial issues, particularly for oil shale and nuclear electricity production. However, the depletion of oil shale is not as critical an issue as the depletion of natural gas and uranium. According to the significance analysis of impact categories, climate change is the most significant impact on the environment in the scenarios. Future decisions on the development of the Estonian energy sector are most likely to be based on technological, economical and political aspects. Political aspects are likely to be the most significant. However, this type of study can give additional value to the discussion due to the increasing role of sustainability in energy issues.

    Highly productive Antarctic shelf systems, like the Ross Sea, play important roles in regional carbon budgets, but the drivers of local variations are poorly quantified. We assess the variability in the Ross Sea carbon cycle using a regional physical-biogeochemical model. Regionally, total partial pressure of CO2 (pCO2) increases are largely controlled by the biological pump and broadly similar to those in the offshore Southern Ocean. However, this masks substantial local variability within the Ross Sea, where interannual fluctuations in total pCO2 are driven by the biological pump and alkalinity, whereas those for anthropogenic pCO2 are related to physical processes. Overall, the high degree of spatial variability in the Ross Sea carbon cycle causes extremes in aragonite saturation that can be as large as long-term trends. Therefore, Antarctic shelf polynya systems like the Ross Sea will be strongly affected by local processes in addition to larger-scale phenomena.

    The study of somatotypes can contribute to the understanding of variability in human body build. The aim of this study was to compare the somatotypes of Italian and Estonian schoolchildren in order to evaluate factors that might lead to variability in somatotypes. The sample consisted of 762 Italian and 366 Estonian children aged 6-11 years. They were somatotyped by the Heath-Carter anthropometric method. Data on organised extra-curricular physical activity and hours of weekly training were also collected. One-way ANOVA was used to evaluate country-related variations of somatotype in each age/sex group, while factorial ANOVA was used to test the influence of country and organised physical activity on the variability of the anthropometric characteristics and somatotype components. There are significant differences in mean somatotypes between the Italian and Estonian children in many age classes and a different constitutional trend in children from the two different countries is observed. The Italian children are more endomorphic and less mesomorphic and ectomorphic than the Estonian children. On the other hand, it emerges from factorial ANOVA, that the somatotype components do not present significant variations related to organised physical activity and to the interaction between the country of origin and sport practice. Moreover, the results of the forward stepwise discriminant analyses show that mesomorphy is the best discriminator between the two countries, followed by ectomorphy. Our findings suggest that the observed differences between Italian and Estonian children could be related mainly to country rather than to the practice of organised physical activity in the two countries.

    Predecessor of todays Estonian Soil Science Society was Estonian Branch of All-Union Soil Society of Soil Scientist which acted from 1957 to 1991. In 1957-1964 Estonian Branch was leaded by prof. Osvald Hallik and in 1964-1991 by prof. Loit Reintam. After re-independence of Estonia in 1991 the society acted in informal way and was leaded by prof. L. Reintam. Non-profit organization "Estonian Soil Science Society" was officially (re)established in 10.23.2009. Estonian Soil Science Society (ESSS) is aimed to: • coordinate collaboration between institutions and individuals intrested of soil science, conservation and sustainable use of soils; • promoting soil science education and research, raising awareness of publicity on topics relating to soils in Estonia; • cooperation between local and foreign unions and associations. In recent years the ESSS had managed to reunite the number of soil scientist from different research institutions of Estonia and of related institutions. Also, the ESSS had provided numerous of materials based on later scientific findings. One of most important activity leaded by ESSS is the organizing Soil Day in Estonia with relevant seminar, where the speakers are sharing latest information with target group (researchers, teachers, policy makers, farmers, students etc.). In a frames of Soil Day the Soil of the Year is selected for Estonia. In 2015, the soil of the year is Leptosol. For current, International Year of the Soil ESSS had planned numerous activities to introduce the importance of soils to wider audience. In current presentation we would like to share the soil science researchers experience through- out the decades of soil science research in Estonia, show our latest findings and designed activities for the International Year of SOIL.

    Full Text Available In this article I attempt to analyse the way in which the Estonian national costume, as heritage, was defined through the cooperation of the state, the museum and ethnographers in the 1930s. The nationalist state wished to strengthen the national identity of Estonia. The Estonian National Museum (ENM as a repository of memory and knowledge availed its resources to support cultural propaganda. The ethnographer Helmi Kurrik, a woman of strong will and keen interest in folk textiles, managed to fulfil her obligation at the expense of her own health. The primary result of her labours was a handbook entitled Eesti rahvarõivad (Estonian Folk Costumes (1938 which has influenced general knowledge of folk costumes in Estonia up to the present day – the ‘right’ national costumes are believed to derive from authentic ethnographical folk costumes held in the Estonian National Museum.

  1. Past ice-sheet behaviour: retreat scenarios and changing controls in the Ross Sea, Antarctica

    Studying the history of ice-sheet behaviour in the Ross Sea, Antarctica's largest drainage basin can improve our understanding of patterns and controls on marine-based ice-sheet dynamics and provide constraints for numerical ice-sheet models. Newly collected high-resolution multibeam bathymetry data, combined with two decades of legacy multibeam and seismic data, are used to map glacial landforms and reconstruct palaeo ice-sheet drainage. During the Last Glacial Maximum, grounded ice reached the continental shelf edge in the eastern but not western Ross Sea. Recessional geomorphic features in the western Ross Sea indicate virtually continuous back-stepping of the ice-sheet grounding line. In the eastern Ross Sea, well-preserved linear features and a lack of small-scale recessional landforms signify rapid lift-off of grounded ice from the bed. Physiography exerted a first-order control on regional ice behaviour, while sea floor geology played an important subsidiary role. Previously published deglacial scenarios for Ross Sea are based on low-spatial-resolution marine data or terrestrial observations; however, this study uses high-resolution basin-wide geomorphology to constrain grounding-line retreat on the continental shelf. Our analysis of retreat patterns suggests that (1) retreat from the western Ross Sea was complex due to strong physiographic controls on ice-sheet drainage; (2) retreat was asynchronous across the Ross Sea and between troughs; (3) the eastern Ross Sea largely deglaciated prior to the western Ross Sea following the formation of a large grounding-line embayment over Whales Deep; and (4) our glacial geomorphic reconstruction converges with recent numerical models that call for significant and complex East Antarctic ice sheet and West Antarctic ice sheet contributions to the ice flow in the Ross Sea.

    Full Text Available This article begins by examining points of intersection between two professional theatres, ”Estonia” and ”Vanemuine” (both established in 1906, their young directors – Karl Menning, Paul Pinna, Theodor Altermann, and Karl Jungholz, and the literary movement Young Estonia. Subsequently, we will consider Young Estonia’s theatrical ideals and the influence of these ideas on later Estonian theatrical life. Since not much information has survived regarding direct personal contacts between ”movers and shakers” in the theatre world and Young Estonians, the main focus here shall be on indirect creative connections and influences. One such context is education: like the Young Estonians, theatre activists of the younger generation aspired to place themselves on the larger map of European culture. Thus, their artistic beliefs and goals shall be examined in relation to those of Young Estonians’ quest for modern culture. Pinna, Altermann, Menning, Jungholz, and others went on study tours to Germany and France, where they were energized and inspired by innovative German and Russian theatres, by naturalistic staging, and by psychological realism, both in acting and in performance style. Among their models were A. Antoine’s Théâtre- Libre in Paris, K. Stanislavski’s Art Theatre in Moscow, O. Brahm’s Lessing-Theater, and M. Reinhardt’s Deutsches Theater in Berlin. These models were likewise known to the Young Estonians, but if theatre activists oriented themselves more fundamentally to German naturalist and realist dramatic art, Young Estonians were more taken with ”theatrical theatre” with its symbolist and impressionist influences. The Young Estonians attended performances at both theatres, ”Vanemuine” and ”Estonia”, and wrote numerous theatre reviews. Yet in the Young Estonia albums (yearbooks and in the magazine Young Estonia, theatre topics have a relatively modest representation. Young Estonians did not have direct

    Lateral drift sheets of outlet glaciers that pass through the Transantarctic Mountains constrain past changes of the huge Ross ice drainage system of the Antarctic Ice Sheet. Drift stratigraphy suggests correlation of Reedy III (Reedy Glacier), Beardmore, Britannia (Hatherton/Darwin Glaciers), Ross Sea (McMurdo Sound), and younger (Terra Nova Bay) drifts; radiocarbon dates place the outer limits of Ross Sea drift in late Wisconsin time at 24,000 to 13,000 yr B.P. Outlet glacier profiles from these drifts constrain late Wisconsin ice sheet surface elevations. Within these constraint, two extreme late Wisconsin reconstructions are given of the Ross ice drainage system. Both show little elevation change of the polar plateau coincident with extensive ice shelf grounding along the inner Ross Embayment. However, in the central Ross Embayment, one reconstruction shows floating shelf ice, where as the other shows a grounded ice sheet. Massive late Wisconsin/Holocene recession of grounded ice from the western Ross Embayment, which was underway at 13,040 yr B.P. and completed by 6600 to 6020 yr B.P., was accompanied by little change in plateau ice levels inland of the Transantarctic Mountains.

  5. Variability and Trends in Sea Ice Extent and Ice Production in the Ross Sea

    Salt release during sea ice formation in the Ross Sea coastal regions is regarded as a primary forcing for the regional generation of Antarctic Bottom Water. Passive microwave data from November 1978 through 2008 are used to examine the detailed seasonal and interannual characteristics of the sea ice cover of the Ross Sea and the adjacent Bellingshausen and Amundsen seas. For this period the sea ice extent in the Ross Sea shows the greatest increase of all the Antarctic seas. Variability in the ice cover in these regions is linked to changes in the Southern Annular Mode and secondarily to the Antarctic Circumpolar Wave. Over the Ross Sea shelf, analysis of sea ice drift data from 1992 to 2008 yields a positive rate of increase in the net ice export of about 30,000 sq km/yr. For a characteristic ice thickness of 0.6 m, this yields a volume transport of about 20 cu km/yr, which is almost identical, within error bars, to our estimate of the trend in ice production. The increase in brine rejection in the Ross Shelf Polynya associated with the estimated increase with the ice production, however, is not consistent with the reported Ross Sea salinity decrease. The locally generated sea ice enhancement of Ross Sea salinity may be offset by an increase of relatively low salinity of the water advected into the region from the Amundsen Sea, a consequence of increased precipitation and regional glacial ice melt.

    2013-12-01

    The northern Antarctic Peninsula is currently warming very rapidly, which has resulted in ice sheet thinning, ice-shelf collapse, and rapid and widespread glacier recession. These small mountain glaciers are predicted to make a large sea level contribution over the coming century. Reconstructing past rates, volumes and magnitudes of change, particularly with respect to the former configuration of former ice sheets and ice shelves, is vital to contextualise contemporary change and to improve predictions of future ice-sheet behaviour. The aim of this research is therefore to investigate the relationship of deglacial ice sheet thinning and Holocene glacier fluctuations around James Ross Island, northeast Antarctic Peninsula, with temperature changes recorded in the Mount Haddington Ice Core. We use a combination of geomorphological mapping, from field campaigns and remotely sensed images, cosmogenic nuclide ages on glacially transported boulders, and numerical modelling with a simple 1D flowline model. Prior to 18 ka, James Ross Island was inundated by a thick and mainly cold-based ice sheet, which scattered granite erratics across the island. Ice sheet thickness and the rate of thinning is constrained by granite erratics on Terrapin Hill (610 m a.s.l.), and from flat-topped mesas at 370 m a.s.l. on Ulu Peninsula. During deglaciation and a period of rapid warming and eustatic sea level rise, the area was drained by Prince Gustav Ice Stream. The ice sheet reached its current configuration by around 6 ka, with glacier readvances around 4-5 ka. At Boulder Valley, near Terrapin Hill on James Ross Island, a large glacial readvance reached the current shoreline. It pre-dated the Mid-Holocene sea level high-stand, and has shorelines imprinted upon its seaward face. After 5.3 cal. ka BP and post-dating the mid-Holocene sea level high-stand, there was a readvance of at least 7 km by glacier 'IJR-45' on Ulu Peninsula. Rapid glacier recession occurred during a period of

    This paper is concerned with the parameter estimation problem for Cox-Ingersoll-Ross model based on discrete observation. First, a new discretized process is built based on the Euler-Maruyama scheme. Then, the parameter estimators are obtained by employing the maximum likelihood method and the explicit expressions of the error of estimation are given. Subsequently, the consistency property of all parameter estimators are proved by applying the law of large numbers for martingales, Holder's inequality, B-D-G inequality and Cauchy-Schwarz inequality. Finally, a numerical simulation example for estimators and the absolute error between estimators and true values is presented to demonstrate the effectiveness of the estimation approach used in this paper.

    Soil quality estimation plays important role in decision making on farm as well on policy level. Sustaining the production ability and good health of the soil the chemical, physical and biological indicators should be taken into account. The system to use soil chemical parameters is usually quite well established in most European counties, including Estonia. However, measuring soil physical properties, such bulk density, porosity, penetration resistance, structural stability ect is time consuming, needs special tools and is highly weather dependent. In that reason these parameters are excluded from controllable quality parameters in policy in Estonia. Within the project "Interactive Soil Quality Assessment in Europe and China for Agricultural Productivity and Environmental Resilience" (iSQAPER) the visual soil assessment (VSA) tool was developed for easy detection of soil quality as well the different soil friendly agricultural management practices (AMP) were detected. The aim of current study was to test the VSA tool on Estonian farm fields under different management practices and compare the results with laboratory measurements. The main focus was set on soil physical parameters. Next to the VSA, the undisturbed soil samples were collected from the depth of 5-10 cm and 25-30 cm. The study revealed that results of a visually assessed soil physical parameters, such a soil structure, soil structural stability, soil porosity, presence of tillage pan, were confirmed by laboratory measurements in most cases. Soil water stable structure measurement on field (on 1 cm2 net in one 1 l box with 4-6 cm air dry clods for 5-10 min) underestimated very well structured soil on grassland and overestimated the structure aggregates stability of compacted soil. The slightly better soil quality was detected under no-tillage compared to ploughed soils. However, the ploughed soil got higher quality points compared with minimum tillage. The slurry application (organic manuring) had

    The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

    The objective of this paper was to find out how many patients with rheumatoid arthritis (RA) know about several aspects of disease, to explain the associations between the level of self-rated knowledge and patients' background and health status and to compare the importance of the main sources of information. A random sample (n = 1,259) of adult Estonian RA patients was selected from the Estonian Health Insurance Fund Database. The patients completed a self-administered questionnaire, which included information about their socio-demographic and disease characteristics, use of health services, information about the disease, and sources of information. Regression analysis was used to calculate the associations between the independent variables and level of self-rated knowledge about several aspects of RA. The results of the study indicated that the self-reported ratings of knowledge about the disease in Estonian RA patients were rather low. Health professionals were mentioned as the primary sources of information, but the longer disease history and more frequent use of health services as considerable predictors of higher ratings of knowledge refer to role of personal experience in obtaining knowledge about the disease as well.

    We present data from an observational cohort study on human immunodeficiency virus (HIV) prevention and control measures in prisons in Estonia to assess the potential for HIV transmission in this setting. HIV testing and retesting data from the Estonian prison health department were used to estimate HIV prevalence and incidence in prison. Since 2002, voluntary HIV counselling and testing has routinely been offered to all prisoners and has been part of the new prisoners health check. At the end of 2012, there were 3,289 prisoners in Estonia, including 170 women: 28.5% were drug users and 15.6% were infected with HIV. Of the HIV-positive inmates, 8.3% were newly diagnosed on prison entry. In 2012, 4,387 HIV tests (including retests) were performed in Estonian prisons. Among 1,756 initially HIV-negative prisoners who were in prison for more than one year and therefore tested for HIV twice within 12 months (at entry and annual testing), one new HIV infection was detected, an incidence of 0.067 per 100 person-years (95% confidence interval (CI): 0.025–5.572). This analysis indicates low risk of HIV transmission in Estonian prisons. Implementation of HIV management interventions could impact positively on the health of prisoners and the communities to which they return.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Uma das cirurgias corretivas para a insuficiência aórtica congênita grave é a cirurgia de Ross. O ecocardiograma transesofágico intraoperatório é indispensável para uma boa avaliação cirúrgica. Além disso, é capaz de avaliar o perfil volêmico e a necessidade de se administrar drogas vasoativas ao longo da cirurgia. RELATO DO CASO: Adolescente de 15 anos apresentava insuficiência aórtica grave de origem congênita, programando-se correção cirúrgica pela técnica de Ross. No centro cirúrgico, o paciente foi monitorado com eletrocardiograma e oxímetro de pulso, recebendo pré-medicação com midazolam. Após a pré-medicação, puncionaram-se a artéria radial esquerda e a veia subclávia direita. A indução anestésica foi feita com etomidato, cisatracúrio e fentanil, e a manutenção anestésica com sevoflurano. A sonda do aparelho do ecocardiograma transesofágico foi introduzida imediatamente após a intubação traqueal e mostrava aumento do ventrículo esquerdo; insuficiência aórtica grave por falha de coaptação dos três folhetos; válvula pulmonar competente sem alterações anatômicas e fisiológicas. A cirurgia transcorreu sem intercorrências, com 120 minutos de circulação extracorpórea (CEC e 8 horas de cirurgia. Imediatamente após a saída de CEC, o ecocardiograma transesofágico mostrava bom funcionamento tanto do auto como do homoenxerto, porém o ventrículo direito encontrava-se hipocontrátil, o que foi corrigido com bolus de milrinona, seguido de infusão contínua. O paciente foi encaminhado ao pós-operatório intubado, estável hemodinamicamente, com infusão de milrinona e nitroprussiato de sódio. CONCLUSÕES: Uma das técnicas de correção da insuficiência aórtica congênita é a cirurgia de Ross, em que o ecocardiograma transesofágico intraoperatório orienta o cirurgião de maneira precisa sobre o status fisiológico e anatômico dos enxertos vasculares.

  19. Frank Ross's Early Direct Photographs of Venus and His Interpretation of Them

    Osterbrock, Donald E.

    2006-09-01

    Frank Ross was an outstandingly creative astronomical "jack of many trades" (Monet) or "cat with nine astronomical lives". After joining the Yerkes Observatory faculty in 1924, at age 50, he took a long series of almost nightly direct photographs of Venus in 1927 with the Mount Wilson 60-inch and 100-inch reflectors as a guest observer. He published many of these images in the ApJ in 1928, with his conclusions on the nature of Venus. Ross discovered markings, seen only in the ultraviolet images, parallel "belts" indicating rotation. They changed rapidly. From these photographs he developed a tentative picture of a deep opaque atmosphere, with high pressure at the surface of the planet. The changes were due to "violent events" (winds or storms) in its atmosphere. From spectroscopic results of Slipher, Adams, StJohn, and Nicholson he took the rotation period to be long. But bolometric observations of Pettit, Nicholson, Coblentz, and Lampland, indicated little temperature change between the illuminated and dark parts of the disk, so it could not be too slow. Ross settled on a "compromise" rotation period of about 30 days based on the data he had. The spectroscopic measurements showed there was very little, if any, H2O or O2 in the atmosphere. Ross is best known today for his Ross wide-angle camera design, his Ross high-proper-motion stars, his Ross photometer, and his Ross correctors for large reflecting telescopes, but his foray into planetary astronomy, long before the era of radar or close-up imaging and spectroscopy from space vehicles, was an important first step toward understanding Venus. His years of experience in laboratory studies of the properties of photographic plates, developers, and mensuration were highly important for this work. Equally so were his cheerful, peppery personality and his close relations with many Mount Wilson and Lowell Observatory staff members.

  2. Neogene Development of the Terror Rift, western Ross Sea, Antarctica

    Terror Rift is a >300 km-long, 50-70 km-wide, 14 km-deep sedimentary basin at the edge of the West Antarctic Rift System, adjacent to the Transantarctic Mountains. It is cut into the broader Victoria Land Basin (VLB). The VLB experienced 100 km of mid-Cenozoic extension associated with larger sea floor spreading farther north. The post-spreading (Neogene) development of Terror Rift is not well understood, in part because of past use of different stratigraphic age models. We use the new Rossmap seismic stratigraphy correlated to Cape Roberts and Andrill cores in the west and to DSDP cores in the distant East. This stratigraphy, and new fault interpretations, was developed using different resolutions of seismic reflection data included those available from the Seismic Data Library System. Depth conversion used a new 3D velocity model. A 29 Ma horizon is as deep as 8 km in the south, and a 19 Ma horizon is >5 km deep there and 4 km-deep 100 km farther north. There is a shallower northern part of Terror Rift misaligned with the southern basin across a 50 km right double bend. It is bounded by steep N-S faults down-dropping towards the basin axis. Between Cape Roberts and Ross Island, the Oligocene section is also progressively-tilted. This Oligocene section is not imaged within northern Terror Rift, but the simplest hypothesis is that some of the Terror Rift-bounding faults were active at least during Oligocene through Quaternary time. Many faults are normal separation, but some are locally vertical or even reverse-separation in the upper couple of km. However, much of the vertical relief of the strata is due to progressive tilting (horizontal axis rotation) and not by shallow faulting. Along the trend of the basin, the relief alternates between tilting and faulting, with a tilting margin facing a faulted margin across the Rift, forming asymmetric basins. Connecting faults across the basin form an accommodation zone similar to other oblique rifts. The Neogene basin is

    Changes in ice shelf mass balance is key to the long term stability of the Antarctic ice sheet. Although the most extensive thinning occurs on the Amundsen Sea sector of West Antarctica, recent studies indicate that many other ice shelves are also experiencing widespread thinning. Here, we focus on the Ross Ice Self. An 18-year record (1994-2012) of satellite radar altimetry shows elevation change 1 m/yr across the shelf. Significant variability in ice shelf height on interannual time scales makes it difficult to detect a long-term mass budget trend of this ice shelf. Variability of radar signal penetration into the ice-shelf snow and firn layers further complicates assessment of mass changes. In this work, we investigate the Ross Ice Shelf mass balance using aerogeophyical data from the ROSETTA-ICE IcePod and NASA's Operation IceBridge. ROSSETTA-ICE is an aerogeophysical program planned to survey the ice shelf at a 10 km spacing over the course of two field seasons-2015 and 2016. This NSF/Moore Foundation supported multi-University collaborative project is designed to provide an integrated view of the ice shelf and the underlying bathymetry using the IcePod system including its ice-penetrating radars, laser altimetry, gravity meters and magnetometers. We present preliminary results from our ongoing efforts of quantifying the mass balance of the ice shelf using IcePod ice penetrating radars and laser altimetry along with satellite data. We will use internal layers traced from ice penetrating radars to outline the structure of the ice shelf. Airborne laser altimetry measurements from this IcePod survey and IceBridge will be used to study the elevation change of the ice shelf. Spatial variations of thickness of the internal layers in the first few meters of the ice shelf, particularly near the grounding line, will indicate the impact of wind-blown snow coming from the continent onto the ice shelf.

    Ronald Ross and George Macdonald are credited with developing a mathematical model of mosquito-borne pathogen transmission. A systematic historical review suggests that several mathematicians and scientists contributed to development of the Ross-Macdonald model over a period of 70 years. Ross developed two different mathematical models, Macdonald a third, and various "Ross-Macdonald" mathematical models exist. Ross-Macdonald models are best defined by a consensus set of assumptions. The mathematical model is just one part of a theory for the dynamics and control of mosquito-transmitted pathogens that also includes epidemiological and entomological concepts and metrics for measuring transmission. All the basic elements of the theory had fallen into place by the end of the Global Malaria Eradication Programme (GMEP, 1955-1969) with the concept of vectorial capacity, methods for measuring key components of transmission by mosquitoes, and a quantitative theory of vector control. The Ross-Macdonald theory has since played a central role in development of research on mosquito-borne pathogen transmission and the development of strategies for mosquito-borne disease prevention.

    The Ross's gull (Rhodostethia rosea) is a poorly known seabird of the circumpolar Arctic. The only place in the world where Ross's gulls are known to congregate is in the near-shore waters around Point Barrow, Alaska where they undertake an annual passage in late fall. Ross's gulls seen at Point Barrow are presumed to originate from nesting colonies in Siberia, but neither their origin nor their destination has been confirmed. Current estimates of the global population of Ross's gulls are based largely on expert opinion, and the only reliable population estimate is derived from extrapolations from previous counts conducted at Point Barrow, but these data are now over 25 years old. In order to update and clarify the status of this species in Alaska, our study quantified the timing, number, and flight direction of Ross's gulls passing Point Barrow in 2011. We recorded up to two-thirds of the estimated global population of Ross's gulls (≥ 27,000 individuals) over 39 days with numbers peaking on 16 October when we observed over 7,000 birds during a three-hour period.

    Directory of Open Access Journals (Sweden)

    Janika Päll

    2012-06-01

    Full Text Available The tradition of translating ancient Greek and Roman authors into Estonian is short, beginning with first attempts at the end of the 18 th century and the close adaptations of two Anacreontic poems (21 and 24 by the first Estonian poet Kristjan Jaak Peterson (in 1818, which remained in manuscript for a long time. The continuous history of printed translations began in 1878 with the translations from Homer by Jaan Bergmann. At present, a new, extensive and regularly updated bibliography with a database of earlier translations is being created (EAB 2012, which also includes the translations in the journals and more extensive citations in articles, as printing separate books with ancient literature started very late (1908 and was very rare in the beginning.  The periods in Estonian translation reflect the history of the country. Almost every period has its own specific trends, beginning with the focus on Greek and the role of periodicals in the first, resembling the patchwork-model of translation that has been described by Karl Eimermacher. Alongside the wish to entertain and educate, we see a strong tendency to use these translations for the development of Estonian national identity by comparing the Estonian epic “Kalevipoeg” to Homer’s epics and translating pieces from Tacitus’ “Germania” as early references to Estonia and thereby extending Estonia’s written history.  The 1920s and 1930s bring first attempts to create a canon, with a stress on Latin and the translations made for school, as well as the development of verse translation. However, all this was disrupted by the almost total abandonment of the classical tradition during the war and the Stalinist period. The comeback in the 1960s brought the translation of central authors from the classical canon (Homer, Vergil, Sophocles, supported by other activities of canon-building (anticipated partly in the 1920s and 1930s: the composition of anthologies and histories of literature

    RV Del is an intrinsic pulsating variable star in the constellation Delphinus, discovered by Ross (1926). The AAVSO list RV Del as a RRAB type of variable star. RV Del has been found to have a magnitude that varies from 12.9 - 14.2 and a period of 11.9553 hours.The purpose of our research of RV Del is to confirm and improve previous results as well as explore different methods to engage middle school students in the scientific method and astronomy. The SKYNET network of telescopes allows students to request images from a group of international research class telescopes. The telescope request process allows students first-hand experience in astronomy while the data analysis allows students to understand advance software systems to produce publishable results. Data is being gathered using the SKYNET network and Stone Edge Observatory to gather photometry of RV Del and create a new light curve. Findings will be presented the January 2017 AAS.

    Congenital heart defects (CHD) occur in 8 per 1000 live births. If they remain untreated, 70-80% of these patients die in early childhood. With modern diagnostic and treatment procedures, 90% of these patients reach adulthood. Within 8 years following reunification of Germany, it was possible to improve treatment for CHD in former East Germany to West German standards. Based on the experience gained in this process, a plan for improvement of care of Estonian patients with CHD was developed and implemented in the German-Estonian project, "Partnership for the Heart". The main elements of the project were (1) the training of Estonian physicians in Germany, (2) training courses conducted by German and Estonian specialists in Estonia and (3) use of telemedicine for consultation on a continuous basis. During the project 15 Estonian patients underwent cardiac surgery and/or catheter interventions performed by a joint team of German and Estonian specialists. The infant mortality due to CHD in Estonia fell by 28% during the project period. Key techniques of cardiac surgery are now being employed in Estonia without outside support, indicating the success of the training program and the long-term improvements to cardiac health care in Estonia. The total project costs were 314,252 Euro (euro), which is 50% lower than the estimated cost of treating the 15 patients abroad in Western Europe. The structure of "Partnership for the Heart" and the modified self-sufficiency model of medical care have not only produced results for Estonia but can be taken as a template for future bilateral health projects with other transition countries and for other fields of medical specialisation, and thus might aid a European health policy.

    Full Text Available From the beginning of the 20th century on, the activities of the Young Estonia literary movement have had a significant influence on the development of Estonian culture. The group published five Young Estonia albums (1905–1915, the magazine Young Estonia, devoted to science, literature, and the arts (1910– 1911, and the newspaper Vaba Sõna (1914–1916, Free Word. The core of the group was composed of five or six active writers who maintained lively interactions with art and theatre circles. The publications of the Young Estonia Press brought about a revolutionary turn in the design and printing styles of the Estonian-language book. The questions of Young Estonia’s role and meaning have intrigued the Estonian cultural public at different times and in different ways. Young Estonia brought to cultural consciousness liberal views on the interpretation of art as well as an elitist aesthetics. At different times their openness to Europe irritated both the nationalist-minded and internationalists; thus the reception of the Young Estonia movement has been polemical throughout Estonian cultural history. Elapsed time has both opened the way for broader generalizations and, conversely, created a need to reconstruct the cultural context of the beginning of the 20th century. Polemic around Young Estonia was certainly caused by the group as a whole; however, in this article the role of individual members is also highlighted. It is emphasized that the political and aesthetic ideas of the Young Estonians changed synchronously with social conditions, from the 1905 Russian revolution to the world war that ravaged Europe. If the early part of this period saw a more social and nationalist bent to their thinking, then in the years of reaction, positions were taken that were more in keeping with l’art pour l’art. Young Estonia was not a hierarchical organization; rather, its small core group was composed of a narrow circle of friends with various

    BACKGROUND: Right ventricular outflow tract (RVOT) conduit dysfunction is a limitation of the Ross procedure. Transcatheter pulmonary valve replacement (TPVR) could alter the impact of conduit dysfunction and the risk-benefit balance for the Ross procedure. METHODS: Retrospective review of databa...... early outcomes and durable valve function in the majority of Ross patients. Recurrent RVOT obstruction associated with stent fracture was the main reason for reintervention. Coronary compression is not uncommon in Ross patients and should be assessed prior to TPVR....... of databases from 3 prospective Melody TPV (Medtronic Inc, Minneapolis, MN) trials. RESULTS: Among 358 patients who were catheterized with the intent to implant a Melody TPV for RVOT conduit stenosis or regurgitation (PR) as part of 3 prospective multicenter studies, 67 (19%) had a prior Ross procedure....... Of these, 56 (84%) received a Melody valve; in 5 of the 11 patients who did not, the implant was aborted due to concern for coronary artery compression, and 1 implanted patient required emergent surgery for left coronary compression. The RVOT gradient decreased from a median 38 mm Hg to 13.5 mm Hg (p

    Full Text Available Background: Immigrants' desire to stay in the host country or return to the country of origin depends largely on the balance between their degree of integration in the host country and their level of attachment to the country of origin. Ethnic diversity is growing rapidly in European countries, including in migrant-sending countries. It may be expected that members of the ethnic minority population and the majority population have different degrees of willingness to engage in return migration depending on their different levels of attachment to their country of origin. Objective: This study examines differences in the return migration intentions of members of the ethnic minority population and members of the majority population in the sending country. Specifically, we seek to answer two main research questions: (1 To what extent do members of the sending country's ethnic minority and majority groups differ in their desire to return to the sending country? (2 How does the degree of integration in the host country shape differences in the return migration intentions of members of the sending country's ethnic minority and majority groups? Methods: We use representative survey data on Estonian migrants in Finland and apply binary logistic regression on our data. Results: Results suggest that there are important differences in the integration levels and in the return migration intentions of the ethnic Estonians and the ethnic Russians from Estonia living in Finland. Despite being much better integrated into Finnish society than ethnic Russians, the ethnic Estonians are much more likely to want to return to Estonia. Indeed, our study shows that ethnicity is one of the most important personal characteristics predicting return migration. Conclusions: There is no obvious negative relationship between integration and return migration. Being a member of the sending country majority population is associated with a stronger intention to return, even when the

    Full Text Available Abstract Introduction Diagnosis and management of Parkinson's disease (PD rely heavily on evaluation of clinical symptoms and patients' subjective perception of their condition. The purpose of this study was to evaluate the validity, acceptability, and reliability of the Estonian version of the 39-question Parkinson 's disease Questionnaire (PDQ-39. Methods Study subjects were approached during their regular clinic follow-up visits. 104 patients consented to the study and 81 completed questionnaires were used for subsequent testing of psychometric characteristics, validity and reliability. Results The content validity was assessed through qualitative content analysis during the pilot study. The patients indicated that the questions were relevant to measure the quality of life of people with PD. The analysis of means showed that the ceiling and floor effects of domain results were within the limits of 15% of Summary Index and of all domains except Stigma, Social Support and Communication where the ceiling effect was 16% to 24% of the responses. Convergent validity was interpreted through correlation between disease severity and PDQ-39 domains. There was a statistically significant difference between the domain scores in patients with mild versus moderate PD in domains of Mobility, ADL, and Communication but not for Stigma, Social Support and Cognition. The reliability was good, Cronbach alpha for all domains and summary index was over 0.8 and item-test correlations between domains and summary index ranged from 0.56 to 0.83. Conclusion The psychometric characteristics of an Estonian version of the PDQ-39 were satisfactory. The results of this study were comparable to the results of previous validation studies in other cultural settings in UK, USA, Canada, Spain and Italy. The Estonian version of the PDQ-39 is an acceptable, valid and reliable instrument for quality of life measurement in PD patients.

    PURPOSE: New maps of some major unconformities of the Ross Sea have been reconstructed, by using seismic data grids, combined with the acoustic velocities from previous works, from new and reprocessed seismic profiles. This work is carried out with the support of PNRA and in the frame of the bilateral Italy-USA project GLAISS (Global Sea Level Rise & Antarctic Ice Sheet Stability predictions), funded by the Ministry of Foreign Affairs. Paleobathymetric maps of 30, 14 and 4 million years ago, three 'key moments' for the glacial history of the Antarctic Ice Sheet, coinciding with global climatic changes. The paleobathymetric maps will then be used for numeric simulations focused on the width and thickness of the Ross Sea Ice Sheet. PRELIMINARY RESULTS: The first step was to create TWT maps of three main unconformity (RSU6, RSU4, and RSU2) of Ross Sea, revisiting and updating the ANTOSTRAT maps, through the interpretation of sedimentary bodies and erosional features, used to infer active or old processes along the slope, we identified the main seismic unconformities. We used the HIS Kingdom academic license. The different groups contribution was on the analysis of the Eastern Ross Sea continental slope and rise (OGS), of the Central Basin (KOPRI) of the western and central Ross Sea (Univ. of Santa Barbara and OGS), where new drill sites and seismic profiles were collected after the publication of the ANTOSTRAT maps. Than we joined our interpretation with previous interpretations. We examined previous processing of several seismic lines and all the old acoustic velocity analysis. In addiction we reprocessed some lines in order to have a higher data coverage. Then, combining the TWT maps of the unconformity with the old and new speed data we created new depth maps of the study area. The new depth maps will then be used for reconstructing the paleobathymetry of the Ross Sea by applying backstripping technique.

    The inactivation mechanism of photocatalytic disinfectants on bacteria is well known. In contrast, the potential inactivation of fungal spores by visible-light induced photocatalysis has been recognized, but the inactivation mechanism is poorly understood. We hypothesize that photocatalytically generated reactive oxygen species (ROSs) are directly involved in this mechanism. To test this hypothesis, we identified the roles of ROSs in the inactivation of Fusarium solani spores. As the photocatalysts, we doped TiO2 with 3 typical dopants, forming Ag/TiO2, N/TiO2 and Er(3+):YAlO3/TiO2. The Ag/TiO2 photocatalysis was dominated by H2O2, with the longest lifetime among the investigated ROSs. Ag/TiO2 photocatalysis yielded almost 100 % inactivation efficiency and preserved the cell-wall shape of the spores, thus minimizing the biomolecule leakage. Er(3+):YAlO3/TiO2 was dominated by h(+) ROSs, yielding an inactivation efficiency of 91 %; however, the severe leakage released large numbers of molecular bio-products. Severe damage to the cell walls by the h(+) species was confirmed in micrograph observations. Subsequent to cell wall breakage, the Er(3+):YAlO3/TiO2 nanoparticles entered the spore cells and directly oxidized the intracellular material. The N/TiO2 photocatalysis, with •O2(-) dominated ROSs, delivered intermediate performance. In conclusion, photocatalysts that generate H2O2-dominated ROSs are most preferred for spore inactivation.

    Full Text Available This study focusses on external factors of second language learning (L2 and their effect on L2 sound production. The aim was to find out whether young adults whose first language (L1 is Estonian speak L2 English with less accent than older speakers of L1 Estonian. Prior studies have claimed that more exposure to the target language lessens the effect of L1 interference (internal factors (e.g. Piske et al. 2001, Muñoz, Llanes 2014. An apparent-time study was imple- mented in order to test whether a change in learner setting (i.e. limited exposure to the target language vs. abundant exposure shows any evidence which can be explained by such external factors. Data was elicited from the speech samples of 97 speakers of L1 Estonian and L1 interference effects were analysed sound by sound. The results show that the younger generation displays less L1 Estonian interference than the older generation. Both greater exposure to the target language and earlier age of L2 learning onset correlate with the ability to produce more sounds target-like.

    Objective. Risk phenotypes for cardiovascular disease (CVD) differ markedly between countries, like the reported high difference in CVD mortality in Austria and Estonia. Hitherto, the goal of this study was to find out risk profiles in body fat distribution yet present in childhood, paving the way for later clinical end points. Methods. he subcutaneous adipose tissue (SAT) distribution patterns in 553 Austrian (A) and Estonian (E) clinically healthy normal weight boys aged 11.1 (±0.8) years were analysed. We applied the patented optical device Lipometer which determines the individual subcutaneous adipose tissue topography (SAT-Top). Results. Total body fat did not differ significantly between E and A boys. A discriminant analysis using all Lipometer data, BMI, and the total body fat (TBF) yielded 84.6% of the boys correctly classified in Estonians and Austrians by 9 body sites. A factor analysis identified the SAT distribution of E as critically similar to male adult patients with coronary heart disease (CHD). Conclusions. We show in normal weight Estonian boys a highly significant decreased fat accumulation on the lower body site compared to age matched Austrian males. This SAT-Top phenotype may play an important role for the increased cardiovascular risk seen in the Estonian population.

    In some areas of Estonia, groundwater contains a significant number of natural radionuclides, especially radium isotopes, which may cause radiation protection concern depending on the geological structure of the aquifer. Indeed, the parametric value of 0.1 mSv y⁻¹ for the total indicative dose established by European Directive 98/83/EC, adopted as a limit value in Estonian national legislation, is often exceeded. A Twinning Project between Estonia and Italy was carried out within the framework of the Estonian Transition Facility Programme, sponsored by the European Union. Its aims were to assess the radiological situation of Estonian groundwater and related health consequences. The first step was a study of Estonian aqueducts and the population served by them, and a thorough analysis of the radiological database for drinking water, from which the relevant effective doses for the population were obtained. Particular attention was devoted to doses to children and infants. Correlations between the chemical parameters were investigated, in order to suggest the best possible analytical approach. Lastly, a monitoring strategy, i.e. sampling points and sampling frequencies, was proposed.

    The content of nitrates were determined in 1,349 samples of vegetables and ready-made food in 2003-2004 as a part of the Estonian food safety monitoring programme and the Estonian Science Foundation grant research activities. The results of manufacturers' analyses carried out for internal monitoring were included in the study. The highest mean values of nitrates were detected in dill, spinach, lettuce and beet root. The mean concentrations were 2,936, 2,508, 2,167 and 1,446 mg kg(-1), respectively. The content of nitrites in samples was lower than 5 mg kg(-1). In total, the mean intake of nitrates by the Estonian population was 58 mg day(-1). The mean content of nitrates in vegetable-based infant foods of Estonian origin was 88 mg kg(-1). The average daily intake of nitrates by children in the age group of 4-6 years was 30 mg. The infants' average daily intake of nitrates from consumption of vegetable-based foods was 7.8 mg.

  12. Lesser snow geese and ross's geese form mixed flocks during winter but differ in family maintenance and social status

    Jonsson, J.E.; Afton, A.D.

    2008-01-01

    Smaller species are less likely to maintain families (or other forms of social groups) than larger species and are more likely to be displaced in competition with larger species. We observed mixed-species flocks of geese in southwest Louisiana and compared frequencies of social groups and success in social encounters of Lesser Snow Geese (Chen caerulescens caerulescens; hereafter Snow Geese) with that of the smaller, closely- related Ross's Geese (C. rossii). Less than 7% of adult and social encounters and had higher odds of success against Ross's Geese than against individuals of their own species. The larger Snow Geese maintain families longer than Ross's Geese, which probably contributes to their dominance over Ross's Geese during winter. Predator vigilance probably is an important benefit of mixed flocking for both species. We suggest the long-standing association with Snow Geese (along with associated subordinate social status) has selected against family maintenance in Ross's Geese.

  13. A Plan for the Future? The Estonian State Integration Programme on National Minorities 2000-2007

    2008-08-01

    Full Text Available Events surrounding the replacement of a Soviet bronze statue in spring 2007 in Tallinn and subsequent international tensions between the EU and Russia marked a low point in inter-ethnic relations between Russian-speakers in Estonia and ethnic Estonians in recent years. This raises the question of how successful current integration efforts directed towards Russian-speakers have actually been. The paper analyzes the development of the Estonian State Integration Programme (SIP 2000-2007 from its earliest moments in the 1990s to its current form. It is argued that although its theoretical basis is well grounded, the programme does not account for minority integration needs systematically. Instead it follows a unidirectional action-plan, targeting Russian-speakers without a prior needs-assessment at grass-root level and insufficient minority participation during the drafting and implementation period. Furthermore, the paper highlights the influence the legal-restorationist concept maintains on the implementation of the SIP which partly has the effect of re-enforcing inter-ethnic alienation.

  14. Groundwater flow model of the Estonian oil shale mining area towards to innovative system

    Lind, H. [Tallinn Univ. of Technology (Estonia). Dept. of Mining

    2010-07-01

    Changes in the Estonian groundwater regime are anticipated as oil shale deposits are mined. This paper described a dynamic groundwater flow model used to develop a 3-D groundwater elevation map of the Estonian oil shale mining area. The model was used to provide preliminary estimations of water inflow into the working underground mine areas. The model included 9 closed underground mines, 5 active mine sites, and 2 small open-cast sites. The closed mine sites were filled with water flowing in from the working mine sites. New mines and dewatering programs are planned for the future. A database from observation wells installed within the Keila-Kukruse aquifer was used to extract outputs and determine time steps. The model included 35 pumping stations from the active mine sites. The hydraulic properties for each model layer were defined in 4 model zones. Results of the model showed higher water in-flows from the closed underground sites than earlier predictions had anticipated. 9 refs., 1 tab., 4 figs.

    The Estonian population-based biobank, with 52,000 participants' genetic and health data, is the largest epidemiological cohort in the Baltic region. Participants were recruited through a network of medical professionals throughout Estonia (population 1.34 million). Unique legislation as well as a broad consent form give the Estonian Genome Center, a research institute of the University of Tartu, permission to re-contact participants and to retrieve participants' data from national registries and databases. In addition to two re-contacting projects to update the health data of participants, extensive clinical characterizations have been retrieved from national registries and hospital databases regularly since 2010. Acquiring data from electronic health records and registries has provided a means to update and enhance the database of the Genome Center in a timely manner and at low cost. The resulting database allows a wide spectrum of genomic and epidemiological research to be conducted with the aim of benefitting public health. Future plans include linking the genome center database with the national health information system through X-road and exchanging data in real time, as well as using the genetic data and the technical infrastructure available for piloting personalized medicine in Estonia.

  16. Herd factors influencing oocyst production of Eimeria and Cryptosporidium in Estonian dairy cattle.

    Cryptosporidium and Eimeria are intestinal parasites which are sensitive to the surroundings, behaviour and well-being of their host. In the present study, a range of factors related to farm management systems, environment, housing and herd characteristics were investigated with regard to alterations in oocyst excretion in cattle, using a mixed-effects model. Information and samples for three age categories were obtained from 45 Estonian dairy farms, located in 15 counties. Leaving the calf with the mother after birth reduced the risk of shedding higher levels of Cryptosporidium (OR = 0.20) and Eimeria (OR = 0.68) oocysts in all animals. The calves younger than 3 months kept on farms housing at least 150 animals had less risk (OR = 0.39) of producing higher numbers of Cryptosporidium oocysts. A somewhat lower infection level was observed in 3- to 12-month-old animals housed in separate buildings (OR = 0.64). The chance of shedding higher levels of Eimeria doubled (OR = 2.27) in cattle older than a year in case a vacancy period was used before replacing animals in pens and tripled (OR = 2.94) when the relative humidity exceeded 75% in the cowshed. Winter reduced the odds (OR = 0.25) of shedding Eimeria oocysts in the oldest animals compared to the fall season. Simple changes in handling and housing of cattle may produce a positive effect on controlling coccidian infections in Estonian dairy herds.

    During the years 2008-2010 I. ricinus and I. persulcatus ticks were collected from 64 sites in mainland Estonia and on the island Saaremaa. Presence of B. miyamotoi was found in 0.9% (23/2622) of ticks. The prevalence in I. persulcatus and I. ricinus ticks differed significantly, 2.7% (15/561) and 0.4% (8/2061), respectively. The highest prevalence rates were in found South-Eastern Estonia in an area of I. persulcatus and I. ricinus sympatry and varied from 1.4% (1/73) to 2.8% (5/178). Co-infections with B. burgdorferi s.l. group spirochetes and tick-borne encephalitis virus were also revealed. Genetic characterization of partial 16S rRNA, p66 and glpQ genes demonstrated that Estonian sequences belong to two types of B. miyamotoi and cluster with sequences from Europe and the European part of Russia, as well as with sequences from Siberia, Asia and Japan, here designated as European and Asian types, respectively. Estonian sequences of the European type were obtained from I. ricinus ticks only, whereas the Asian type of B. miyamotoi was shown for both tick species in the sympatric regions.

    Full Text Available This article aims to give an overview of literary instruction in schools of the russification era at the beginning of the 20th century in Estonia; this was likewise the curriculum of literary study offered to the generation of educated youth which included the Young Estonians. Based on official documents, archival materials, and memoirs, and through analyses of anthologies, literary histories, and teaching methods in use at the time, we attempt to reconstruct the outlines of literary reading and requirements for students in various types of schools. When, as a result of school reform, Russian became the language of instruction; lessons in Russian became central in the curriculum, alongside the word of God; selections from Russian literature were read in the original language. In the lower grades, teaching was by the so-called ”natural method”, intended to guarantee swift achievement of fluency in ”living Russian language”; this was later replaced by systematic textual analysis, which distinguished between belles lettres and other types of texts. However, the study of literature was always subordinated to the goals of language instruction. In institutions of secondary education, study of Russian literature was separate from language instruction. Indeed, Russian literature was the only literature systematically studied in high schools (though one must keep in mind that not all schools completely followed the official program. Private schools were especially noticeable for their greater freedom, though all of them had to take general curriculum directives into account. Reading of literary texts connected with other languages thus had to remain almost purely illustrative. In view of the above, in the upper grades of elementary school and high school, students obtained a thorough introduction to the Russian classics. According to the official school curriculum, Russian literary history ended with Nikolai Gogol. Attempts were made to ignore

    Full Text Available INTRAMAP (INtegrated Transantarctic Mountains and Ross Sea Area Magnetic Anomaly Project is an international effort to merge the magnetic data acquired throughout the "Ross Sea Antarctic Sector" (south of 60°S between 135°-255°E including the Transantarctic Mountains (TAM, the Ross Sea, Marie Byrd Land, and the Pacific coast, and also to begin the compilation efforts for new data over the Wilkes Basin. This project is a component of the continental scale Antarctic Digital Magnetic Anomaly Project (ADMAP. The first stage of INTRAMAP addresses the analysis and merging of GITARA (1991-1994 and GANOVEX (1984 aeromagnetic surveys together with ground magnetic data (1984-1989. The combined data sets cover an area of approximately 30 km2 over Victoria Land and adjacent Ross Sea. Map and profile gridding were implemented to integrate the data sets. These approaches are studied for improving existing strategies to adopt for the whole magnetic compilation effort. The final microlevelled grid that we produce is a new tool for regional interpretation of the main tectonic and geologic features of this sector of Antarctica.

  5. TEST OF THE CHEN-ROLL-ROSS MACROECONOMIC FACTOR MODEL: EVIDENCE FROM CROATIAN STOCK MARKET

    2015-12-01

    Full Text Available This paper empirically examines the well-known Chen-Roll-Ross model on the Croatian stock market. Modifications of definitions of the Chen-Roll-Ross model variables showed as necessary because of doubtful availability and quality of input data needed. Namely, some macroeconomic and market variables are not available in the originally defined form or do not exist. In that sense this paper gives some alternative definitions for some model variables. Also, in order to improve statistical analysis, in this paper we have modified Fama-MacBeth technique in the way that second-pass regression was substituted with panel regression analysis. Based on the two-pass regression analysis of returns of 34 Croatian stocks on 4 macroeconomic variables during the seven-and-half-year observation period the following conclusion is made. In contrast to the results of Chen, Roll and Ross (1986 for the U.S. stock market, their model is not successful when describing a risk-return relation of Croatian stocks. Nevertheless, one observed version of the Chen-RollRoss model showed certain statistical significance. Namely, two risk factors in that version of the model were statistically significant: default premium, measured as risk premium for the corporate short-term bank loan financing, and term structure premium, measured on short-run basis.

    During the CLIMA Project (R.V. Italica cruise PNRA XVI, January-February 2001), hydrographic and chlorofluorocarbons (CFCs) observations were obtained, particularly in the western Ross Sea. Their distribution demonstrated water mass structure and ventilation processes in the investigated areas. In the surface waters (AASW) the CFC saturation levels varied spatially: CFCs were undersaturated in all the areas (range from 80 to 90%), with the exception of few stations sampled near Ross Island. In particular, the Terra Nova Bay polynya, where high salinity shelf water (HSSW) is produced, was a low-saturated surface area (74%) with respect to CFCs. Throughout most of the shelf area, the presence of modified circumpolar deep water (MCDW) was reflected in a mid-depth CFC concentration minima. Beneath the MCDW, CFC concentrations generally increased in the shelf waters towards the seafloor. We estimated that the corresponding CFCs saturation level in the source water region for HSSW was about 68-70%. Waters with high CFC concentrations were detected in the western Ross Sea on the down slope side of the Drygalski Trough, indicating that AABW was being supplied to the deep Antarctic Basin. Estimates of ventilation ages depend strongly on the saturation levels. We calculated ventilation ages using the saturation level calibrated tracer ratio, CFC11/CFC12. We deduced a mean residence time of the shelf waters of about 6-7 years between the western Ross Sea source and the shelf break.

    The bioavailability of iron influences the distribution, biomass and productivity of phytoplankton in the Ross Sea, one of the most productive regions in the Southern Ocean. We mapped the spatial and temporal extent and severity of iron-limitation of the native phytoplankton assemblage using long- (> 24 h) and short-term (24 h) iron-addition experiments along with physiological and molecular characterisations during a cruise to the Ross Sea in December-February 2012. Phytoplankton increased their photosynthetic efficiency in response to iron addition, suggesting proximal iron limitation throughout most of the Ross Sea during summer. Molecular and physiological data further indicate that as nitrate is removed from the surface ocean the phytoplankton community transitions to one displaying an iron-efficient photosynthetic strategy characterised by an increase in the size of photosystem II (PSII) photochemical cross section (σPSII) and a decrease in the chlorophyll-normalised PSII abundance. These results suggest that phytoplankton with the ability to reduce their photosynthetic iron requirements are selected as the growing season progresses, which may drive the well-documented progression from Phaeocystis antarctica- assemblages to diatom-dominated phytoplankton. Such a shift in the assemblage-level photosynthetic strategy potentially mediates further drawdown of nitrate following the development of iron deficient conditions in the Ross Sea.

    The tidal impact on overflow dynamics and bottom water production in the western Ross Sea is studied with the Finite Element Ocean Model, which allows embedding a mesh with 0.5 km resolution in a coarse resolution (30 km) setup without nesting. The simulated overflow properties inside and downstream of the western Ross Sea are described. The overflow exhibits pronounced variability at both daily and spring-neap tidal time scales in the western Ross Sea. Tides increase mixing over both the outer shelf and upper slope there. Plume jets are shaped by tidal currents at a bathymetric bend west of the Drygalski Trough mouth, descending rapidly and supplying the bottom water. A fraction of shelf water remains over the shelf and propagates westward from the Ross Sea, but it does not contribute significantly to bottom water formation because of energetic mixing over the upper slope. Compared to a simulation without tidal forcing, tides (with the major K1 and O1 constituents) increase the outflow rate over the continental slope off Cape Adare by about 70%. A set of sensitivity experiments show that the rate of bottom water production is not a monotonic function of the tidal currents amplitude. Tidal forcing with intermediate strength leads to the most efficient bottom water formation.

    We investigate the impacts of strong wind events on the sea ice concentration within the Ross Sea polynya (RSP), which may have consequences on sea ice formation. Bootstrap sea ice concentration (SIC) measurements derived from satellite SSM/I brightness temperatures are correlated with surface winds and temperatures from Ross Ice Shelf automatic weather stations (AWSs) and weather models (ERA-Interim). Daily data in the austral winter period were used to classify characteristic weather regimes based on the percentiles of wind speed. For each regime a composite of a SIC anomaly was formed for the entire Ross Sea region and we found that persistent weak winds near the edge of the Ross Ice Shelf are generally associated with positive SIC anomalies in the Ross Sea polynya and vice versa. By analyzing sea ice motion vectors derived from the SSM/I brightness temperatures we find significant sea ice motion anomalies throughout the Ross Sea during strong wind events, which persist for several days after a strong wind event has ended. Strong, negative correlations are found between SIC and AWS wind speed within the RSP indicating that strong winds cause significant advection of sea ice in the region. We were able to partially recreate these correlations using colocated, modeled ERA-Interim wind speeds. However, large AWS and model differences are observed in the vicinity of Ross Island, where ERA-Interim underestimates wind speeds by a factor of 1.7 resulting in a significant misrepresentation of RSP processes in this area based on model data. Thus, the cross-correlation functions produced by compositing based on ERA-Interim wind speeds differed significantly from those produced with AWS wind speeds. In general the rapid decrease in SIC during a strong wind event is followed by a more gradual recovery in SIC. The SIC recovery continues over a time period greater than the average persistence of strong wind events and sea ice motion anomalies. This suggests that sea ice

    Reduction in the area and volume of Earth?s two polar ice sheets is intricately linked to changes in global climate and to the resulting rise in sea level. Measurement of changes in area and mass balance of the Antarctic ice sheet was given a very high priority in recommendations by the Polar Research Board of the National Research Council. On the basis of these recommendations, the U.S. Geological Survey used its archive of satellite images to document changes in the cryospheric coastline of Antarctica and analyze the glaciological features of the coastal regions. The Ross Island area map is bounded by long 141? E. and 175? E. and by lat 76? S. and 81? S. The map covers the part of southern Victoria Land that includes the northwestern Ross Ice Shelf, the McMurdo Ice Shelf, part of the polar plateau and Transantarctic Mountains, the McMurdo Dry Valleys, northernmost Shackleton Coast, Hillary Coast, the southern part of Scott Coast, and Ross Island. Little noticeable change has occurred in the ice fronts on the map, so the focus is on glaciological features. In the western part of the map area, the polar plateau of East Antarctica, once thought to be a featureless region, has subtle wavelike surface forms (megadunes) and flow traces of glaciers that originate far inland and extend to the coast or into the Ross Ice Shelf. There are numerous outlet glaciers. Glaciers drain into the McMurdo Dry Valleys, through the Transantarctic Mountains into the Ross Sea, or into the Ross Ice Shelf. Byrd Glacier is the largest. West of the Transantarctic Mountains are areas of blue ice, readily identifiable on Landsat images, that have been determined to be prime areas for finding meteorites. Three subglacial lakes have been identified in the map area. Because McMurdo Station, the main U.S. scientific research station in Antarctica, is located on Ross Island in the map area, many of these and other features in the area have been studied extensively. The paper version of this map is

    The stability of modern ice shelves is threatened by atmospheric and oceanic warming. The geologic record of formerly glaciated continental shelves provides a window into the past of how ice shelves responded to a warming climate. Fields of deep (-560 m), linear iceberg furrows on the outer, western Ross Sea continental shelf record an early post-Last Glacial Maximum episode of ice-shelf collapse that was followed by continuous retreat of the grounding line for ∼200 km. Runaway grounding line conditions culminated once the ice became pinned on shallow banks in the western Ross Sea. This early episode of ice-shelf collapse is not observed in the eastern Ross Sea, where more episodic grounding line retreat took place. More widespread (∼280,000 km(2)) retreat of the ancestral Ross Ice Shelf occurred during the late Holocene. This event is recorded in sediment cores by a shift from terrigenous glacimarine mud to diatomaceous open-marine sediment as well as an increase in radiogenic beryllium ((10)Be) concentrations. The timing of ice-shelf breakup is constrained by compound specific radiocarbon ages, the first application of this technique systematically applied to Antarctic marine sediments. Breakup initiated around 5 ka, with the ice shelf reaching its current configuration ∼1.5 ka. In the eastern Ross Sea, the ice shelf retreated up to 100 km in about a thousand years. Three-dimensional thermodynamic ice-shelf/ocean modeling results and comparison with ice-core records indicate that ice-shelf breakup resulted from combined atmospheric warming and warm ocean currents impinging onto the continental shelf.

    The Ross Ice Shelf, located in the embayment between East and West Antarctica, is one of the largest underexplored patches of ocean on the planet. Sediment cores show that the Ross Ice Shelf can disintegrate during some interglacial periods. The conditions required for sudden collapse are not well constrained. A key to understanding the dynamics and long-term stability of the Ross Ice Shelf system is having high-resolution constraints on its boundary conditions, including sea floor bathymetry. The sea floor under the Ross Ice Shelf has developed in response to both the tectonic development of the West Antarctic Rift and the glacial signature of the waxing and waning Antarctic Ice Sheets. A mixture of fabrics and orientations in its bathymetry reflect this complex development. However, present oceanographic models of water circulation under the ice are based on low-resolution bathymetric maps drawn from stations spaced 55 km apart obtained during the RIGGS project in the 1970s. In contrast, most of the bathymetry of the world's oceans has been mapped to approximately 15 km resolution from satellite altimetry and much higher resolution from acoustic surveys. Improvement of Ross Ice Shelf bathymetry can be achieved from combined analysis and inversion of gravity and magnetic data acquired from airborne surveys over the Ross Ice Shelf. Survey lines flown in 2013 by Operation IceBridge, with the Sander Geophysics Ltd AIRGrav system over the central and northern Ross Embayment provide a tenfold increase, to 5 km, of the along track resolution of bathymetry. Newly resolved bathymetric highs and lows have amplitudes of up to 200 km. Combining the gravity and magnetic surveys also reveals the differing geology across the embayment. Results from these surveys, including comparison with ship-based bathymetry data from the Ross Sea, demonstrate the value of gravity and magnetic surveys for mapping the bathymetry of the Ross Ice Shelf and the need for more comprehensive

    In response to public concern, this study assessed the fatty acid (FA) composition of blended spreads, margarines and shortenings in the Estonian retail market in 2011. Special attention was paid to the trans fatty acids (TFA) composition. The changes in these characteristics of selected dietary fats in the market over recent years are also presented. Twenty-six edible fat brands, available in the Estonian retail market in 2011, were purchased and FA compositions were analyzed by chromatography. Saturated fatty acids (SFA) were the dominant group of FAs for all blended spreads (49.6 to 65.8%), and for the majority of shortenings (from 21.1 to 54.6%). Cis monounsaturated fatty acids (MUFA) were the dominant group of FAs for the majority of margarines, ranging from 25.3% to 50.5%. The total TFA for blended spreads varied from 1.18% to 9.08%, for margarines from 0.04% to 34.96% and for shortenings from 0.14% to 39.50%. Octadecenoic (C18:1) isomers were the main TFA found. Compared to 2008/2009, the industrially produced TFA (IP-TFA) content in several of the dietary fat brands was much reduced in 2011. This voluntary reformulation was probably a response to consumer demand associated with a public health campaign directed against IP-TFA in Estonian foods, and were mainly achieved by replacing TFA with SFA C12:0-C16:0. Present paper is directed toward public health related institutions and food industries producing foods with potentially high contents of trans fatty acids (TFA). According to the public concern TFA content in domestic blended spreads has declined significantly over the past 3 y in Estonia. The reduction in the TFA content was achieved by replacing TFA with saturated fatty acids (SFA) (C12:0-C16:0). To shift food composition toward healthier product formulations, mandatory labeling of the sum of IP-TFA and SFA (C12:0-C16:0) was recommended. © 2012 Institute of Food Technologists®

    Full Text Available The governmental initiative called the Compatriots Programme, which supports language tuition in Estonian schools and societies abroad, reveals an increased interest in developing intergenerational language transmission in the growing Estonian diaspora. This transnational language political activity signals a new era in language policy, where nation states are increasingly decentralized by migration. The evaluation of the program furthermore reveals that organizing such schools requires a willingness to take language political agency, typically conducted by well-educated and well-integrated resourceful transnational multilingual parents. The present article outlines the results of an ethnographic study of the process of establishing the Estonian School in Copenhagen. This step has demanded a change in the mindset still prevailing in Estonia that language political activities, such as planning language acquisition, are solely the responsibility of the state. Since the prevailing language ideology in Denmark is not favorable towards multilingualism in migrant languages, intergenerational language transmission furthermore presupposes a feeling of ownership of the language and high language self-esteem.

    Conclusions: The Ross and Ross-Konno operations have changed the prognosis of pediatric patients with complex disease of the valve and aortic root. There is growth of the neo-aortic root in young patients. Sinotubular dilatation of the autograft with neoaortic valve insufficiency has been detected in patients with previously dilated aortic root when root replacement technique was performed. The best results are obtained in the younger andlower weight patients with complex left ventricular outflow obstruction without root dilatation. A close follow-up of patients with aortic root dilatation is mandatory to definitely validate the Ross procedure over aortic prosthesis.

    Satellites have provided us with a remarkable ability to monitor many aspects of the globe day-in and day-out and sea ice is one of numerous variables that by now have quite substantial satellite records. Passive-microwave data have been particularly valuable in sea ice monitoring, with a record that extends back to August 1987 on daily basis (for most of the period), to November 1970 on a less complete basis (again for most of the period), and to December 1972 on a less complete basis. For the period since November 1970, Ross Sea sea ice imagery is available at spatial resolution of approximately 25 km. This allows good depictions of the seasonal advance and retreat of the ice cover each year, along with its marked interannual variability. The Ross Sea ice extent typically reaches a minimum of approximately 0.7 x 10(exp 6) square kilometers in February, rising to a maximum of approximately 4.0 x 10(exp 6) square kilometers in September, with much variability among years for both those numbers. The Ross Sea images show clearly the day-by-day activity greatly from year to year. Animations of the data help to highlight the dynamic nature of the Ross Sea ice cover. The satellite data also allow calculation of trends in the ice cover over the period of the satellite record. Using linear least-squares fits, the Ross Sea ice extent increased at an average rate of 12,600 plus or minus 1,800 square kilometers per year between November 1978 and December 2007, with every month exhibiting increased ice extent and the rates of increase ranging from a low of 7,500 plus or minus 5,000 square kilometers per year for the February ice extents to a high of 20,300 plus or minus 6,100 kilometers per year for the October ice extents. On a yearly average basis, for 1979-2007 the Ross Sea ice extent increased at a rate of 4.8 plus or minus 1.6 % per decade. Placing the Ross Sea in the context of the Southern Ocean as a whole, over the November 1978-December 2007 period the Ross Sea had

    A detailed study of gravel-size sedimentary clasts in the ANDRILL-2A (AND-2A) drill core reveals distinct changes in provenance and allows reconstructions to be produced of the paleo ice flow in the McMurdo Sound region (Ross Sea) from the Early Miocene to the Holocene. The sedimentary clasts in AND-2A are divided into seven distinct petrofacies. A comparison of these with potential source rocks from the Transantarctic Mountains and the coastal Southern Victoria Land suggests that the majority of the sedimentary clasts were derived from formations within the Devonian-Triassic Beacon Supergroup. The siliciclastic-carbonate petrofacies are similar to the fossiliferous erratics found in the Quaternary Moraine in the southern McMurdo Sound and were probably sourced from Eocene strata that are currently hidden beneath the Ross Ice Shelf. Intraformational clasts were almost certainly reworked from diamictite and mudstone sequences that were originally deposited proximal to the drill site. The distribution of sedimentary gravel clasts in AND-2A suggests that sedimentary sequences in the drill core were deposited under two main glacial scenarios: 1) a highly dynamic ice sheet that did not extend beyond the coastal margin and produced abundant debris-rich icebergs from outlet glaciers in the central Transantarctic Mountains and South Victoria Land; 2) and an ice sheet that extended well beyond the coastal margin and periodically advanced across the Ross Embayment. Glacial scenario 1 dominated the early to mid-Miocene (between ca. 1000 and 225 mbsf in AND-2A) and scenario 2 the early Miocene (between ca. 1138 and 1000 mbsf) and late Neogene to Holocene (above ca. 225 mbsf). This study augments previous research on the clast provenance and highlights the added value that sedimentary clasts offer in terms of reconstructing past glacial conditions from Antarctic drill core records.

    Full Text Available The article presents the attitude of grammar school students towards the art curriculum. It first provides an overview of the characteristics of contemporary art education, with an emphasis on the postmodern art curriculum and on linking course content with students’ interests. The study is based on the descriptive and causal non-experimental method, with a sample comprising 387 Slovenian, Estonian and Portuguese students. It was established that the students place the highest value on developing creativity, and are less interested in art history content and learning about the basics of the formal art language. They are attracted to contemporary topics, such as graffiti, multicultural art, the use of new media, and digital technologies. The results of the study provide opportunities for future comparative analyses and starting points for updating art curricula.

    Estonia is the worldwide leading producer of the fuel oils from the oil shale. We evaluated the ecotoxicity of water accommodated fraction (WAF) of two Estonian shale fuel oils ("VKG D" and "VKG sweet") to aquatic species belonging to different trophic levels (marine bacteria, freshwater crustaceans and aquatic plants). Artificial fresh water and natural lake water were used to prepare WAFs. "VKG sweet" (lower density) proved more toxic to aquatic species than "VKG D" (higher density). Our data indicate that though shale oils were very toxic to crustaceans, the short-term exposure of Daphnia magna to sub-lethal concentrations of shale fuel oils WAFs may increase the reproductive potential of survived organisms. The weak correlation between measured chemical parameters (C10-C40 hydrocarbons and sum of 16 PAHs) and WAF's toxicity to studied species indicates that such integrated chemical parameters are not very informative for prediction of shale fuel oils ecotoxicity.

  11. Recent trends in chemical composition of bulk precipitation at Estonian monitoring stations 1994-2001

    Treier, K.; Pajuste, K.; Frey, J.

    Monthly and annual means of main anions (SO 42-, NO 3-, Cl -) and summed base cations (Ca 2+, Mg 2+, K +, Na +) in bulk precipitation were studied at 10 stations during an 8-year monitoring period. The data showed statistically significant decreasing trends in most cases. Average declines of mean annual volume-weighted concentrations for both anions and cations were about two-fold. Despite the decrease, the loads of S and cations are still relatively high in Estonia (about 4-14 kg S ha -1 and 0.6-1.2 keq ha -1, respectively) compared with the loads in Finland and Sweden. Estimated linear decline trends followed the same pattern as annually combusted oil shale from Estonian power plants and emissions of SO 2 and fly ash. Recent trends in chemical composition of bulk precipitation at the monitoring stations reflected economic changes in Estonia as well as transboundary fluxes from neighbouring countries.

    2004-12-01

    Full Text Available The article investigates Votic, Estonian and Setu Kalevala-metric folk songs, which describe a dialogue between a living person and his or her deceased relative. The analysis centres on religious truth in poetic texts, relying on corresponding approaches by Ülo Valk and Aado Lintrop. As the observed texts are no longer mytho-epic stories or laments, the question about the meaning in lyro-epic discourse is discussed and particular attention is paid to the changes in concepts of time, the plot and characters of the songs. The author introduces the key concept ‘epiphany’ as a tool constructing meaning and merging the actual situation, the song text and personal emotions into a creative whole for the singer and/ or the audience.

    National e-Prescription services are becoming more common in Europe. While enhancing communication between levels of health care, few solutions have demonstrated enhanced quality of care and patient safety benefits. The article presents the results of a project to map the user needs the Estonian national e-prescription service. A survey was conducted among primary care physicians (PCPs) to inquire about their needs in the medication management process. The results showed that PCPs lacked a medication management tool to support patient care across different care settings. A mockup for the national service was developed based on the survey results. The medication management tool features a visual presentation of a patient's medication list and includes decision support functions for allergies and potential interactions. This mockup will be used to further investigate the needs of PCPs as well as other care providers in the medication management process.

    We studied effects of mate removal on nesting and hatching success, incubation behavior, body mass, and post-hatch dispersal distance of female Ross' (Chen rossii) and Lesser Snow Geese (C. caerulescens caerulescens) at Karrak Lake. N.W.T., Canada. Male ge and widowed and paired control females were monitored through post-hatch dispersal. Nesting and hatching success did not differ between species or treatments (widowed vs paired) and averaged 77.5 ?? 3.8% and 64.0 ?? 3.6% (??SE), respectively. Paired females spent more time with their bills tucked (23.7 ?? 3.3% vs 9.1 ?? 4.0%) and less time alert (8.6 ?? 2.9% vs 22.9 ?? 3.5%) while on nests than did widowed females. Snow widowed females (31.1 ?? 4.7%) and Ross' widowed females (20.6 ?? 6.0%) generally spent more time each day in head-up alert than did Snow paired females (7.1 ?? 3.8%). Snow paired maleS (11.8 ?? 3.8%), Ross' paired females (9.4 ?? 3.6%), and Ross' paired males (7.9 ?? 3.6%). Body mass of paired and widowed female Ross' Geese did not differ at hatch or at time of post-hatch recapture; however, mean distance recaptured from the breeding colony was greater for paired (50.9 ?? 6.1 km) than for widowed females (27.3 ?? 6.6 km). Total mass gain (276 ?? 19 g) and rate of mass gain (8.4 ?? 0.5 g/day), from hatch until post-hatch recapture (33.1 ?? 1.2 days), were similar for widowed and paired female Ross' Geese. Male removal experiments in monogamous, precocial species generally have produced few effects on female nesting success or incubation behavior. We suggest that male parental care in arctic-nesting geese is more critical during laying and the post-hatch period than during incubation.

    Chromosomal microarray analysis (CMA) is now established as the first-tier cytogenetic diagnostic test for fast and accurate detection of chromosomal abnormalities in patients with developmental delay/intellectual disability (DD/ID), multiple congenital anomalies (MCA), and autism spectrum disorders (ASD). We present our experience with using CMA for postnatal and prenatal diagnosis in Estonian patients during 2009-2012. Since 2011, CMA is on the official service list of the Estonian Health Insurance Fund and is performed as the first-tier cytogenetic test for patients with DD/ID, MCA or ASD. A total of 1191 patients were analyzed, including postnatal (1072 [90%] patients and 59 [5%] family members) and prenatal referrals (60 [5%] fetuses). Abnormal results were reported in 298 (25%) patients, with a total of 351 findings (1-3 per individual): 147 (42%) deletions, 106 (30%) duplications, 89 (25%) long contiguous stretches of homozygosity (LCSH) events (>5 Mb), and nine (3%) aneuploidies. Of all findings, 143 (41%) were defined as pathogenic or likely pathogenic; for another 143 findings (41%), most of which were LCSH, the clinical significance remained unknown, while 61 (18%) reported findings can now be reclassified as benign or likely benign. Clinically relevant findings were detected in 126 (11%) patients. However, the proportion of variants of unknown clinical significance was quite high (41% of all findings). It seems that our ability to detect chromosomal abnormalities has far outpaced our ability to understand their role in disease. Thus, the interpretation of CMA findings remains a rather difficult task requiring a close collaboration between clinicians and cytogeneticists.

    Poor efficacy of anthelmintic drugs in sheep due to infections with resistant gastrointestinal strongyles is reported worldwide. The aim of this pilot study was to gain an insight into the current situation of anthelmintic efficacy in Estonian sheep flocks. From September to November 2012, faecal egg count reduction tests (FECRT) were carried out in three Estonian sheep farms, evaluating the efficacy of albendazole and ivermectin. Individual faecal samples were taken at the day of treatment and 10 to 14 days later and examined by a modified McMaster technique. Anthelmintic treatment was carried out with ivermectin (Bimectin 10 mg/ml, Bimeda Chemicals Export) subcutaneously with a dose rate of 0.2 mg/kg of body weight in the IVM group (n = 20 animals/farms 1 and 2; n = 5 for farm 3) or albendazol (Endospec 10%, Bimeda Chemicals Export) orally in the dose of 5 mg/kg of body weight in the ALB group (n = 20 animals/ farm); animals in the control group (n = 20 animals for farms 1 and 3, n = 18 for farm 2) were left untreated. The FECRT was carried out according to the WAAVP guidelines. On farm 1 the efficacy of albendazole and ivermectin was reduced with 66% and 65% FECR, respectively. With a FECR of 26% the results of farm 2 showed a pronounced albendazole resistance while ivermectin was still sufficiently efficient (99% reduction). Farm 3 showed nearly 100% efficacy of albendazole and ivermectin, but earlier problems with high endoparasite burden and mortality may indicate a possible developing albendazole resistance which could not be detected with the FECRT yet. The results of this study show that in Estonia resistance against benzimidazoles and macrocyclic lactones does occur, indicating that close countrywide monitoring is advisable.

    2011-10-01

    We aimed to examine the associations of sleep duration with time spent on sedentary, moderate and vigorous activities in children and adolescents. The sample consisted of 2,241 (53.5% girls) Estonian and Swedish children (9-10 years) and adolescents (15-16 years), from the European Youth Heart Study, in 1998-1999. Sleep duration was calculated by the difference between self-reported bedtime and time for getting up on a normal weekday. Sedentary time/physical activity was measured by accelerometry (valid data on 1,462 participants). Adolescents had lower odds than children, and Swedish higher odds than Estonian, of meeting the sleep recommendations (>9 h) (OR = 0.22, 95% CI 0.17-0.27; and 1.32, 1.07-1.61, respectively). Participants sleeping longer than 10 h spent more time on physical activities (all intensities) and less time on sedentary activities than those sleeping shorter durations (all P < 0.001). The associations with physical activity became non-significant after additional adjustment for age or sexual maturation (Tanner stages), whereas the associations with sedentary time became borderline significant (P = 0.09/0.03, for age and Tanner, respectively). In conclusion, these results do not suggest a link between sleep durations and activity in a relatively large sample of children and adolescents from two European countries. Consequently, the common assumption that physical activity is a mediator in the relationship between short sleep durations and obesity is not supported by our findings.

    2016-01-01

    Full Text Available The purpose of this paper is to investigate the market structure and degree of concentration of Bangladeshi banking industry. The study measured market concentration by using widely recognized measures like k-bank concentration ratio and Herfindahl-Hirchman Index (HHI. It evaluates market structure by applying Panzar-Rosse Model over 8 years period from 2006 to 2013. The result of concentration measures indicates a decreasing trend and low level of market concentration in Bangladeshi banking industry over the sample period. The panzer-Rosse “H-Statistic” suggests that banks in Bangladesh are operating under monopolistic competition. Present paper contributes to a burgeoning literature on banking competition that has evolved significantly over the past periods on a developing country perspective like Bangladesh.

    A case of percutaneous pulmonary valve implantation following a failed homograft in the pulmonary position is reported. A 16-year-old boy developed infective endocarditis of his pulmonary homograft, which was implanted four years earlier during a Ross procedure for congenital aortic stenosis. Following successful medical therapy, the boy was symptomatic due to pulmonary stenosis and regurgitation. A 22 mm Melody valve (Medtronic, USA) was successfully implanted percutaneously. His symptoms resolved and he was discharged home one day after the procedure. Echocardiography at the six-month follow-up demonstrated a normally functioning pulmonary valve. Percutaneous pulmonary valve replacement may make the Ross procedure a more attractive option for patients with aortic stenosis, particularly in the pediatric population.

  2. A Battle of Words: "Dignity" and "Peace" in the Writings of Elisabeth Kübler-Ross.

    Science.gov (United States)

    Burnier, Daniel

    2017-01-01

    This article analyzes the writings of Elisabeth Kübler-Ross through the discursive lens of the phrase "dying with dignity." For her, the phrase meant allowing someone to die comfortably his/her own death. This phrase has to be understood in relationship with the final "stage of acceptance" of her model. Describing this key part of her well-known scientific output, she often used, in the early 1970s, the phrase "dying in peace and dignity." An evaluation of the evidence suggests that because the concept of dignity was co-opted by the pro-euthanasia movement during this decade, the language of dignity was little by little abandoned by her. In later years, only "peace" survived from her favorite expression. Although this concept of peace remains present to the end in all Kübler-Ross writings, the pro-euthanasia movement has also started to speak the language of peace.

  3. How to Improve the Supportive Role of Estonian Innovation System toward Launching New Products by High Technology Companies?

    2013-01-01

    Full Text Available The purpose of the study is to evaluate how supportive is Estonian national innovation system toward the launching of new innovative products by high technology firms. The article intends to combine two broad areas of research – national innovation system approach and the different models of the new product launching. Based on the literature review and in-depth analysis of three case studies of Estonian high-tech company’s major barriers as well success factors of highly innovative product launches were identified. The barriers of the new product launching were linked with the systemic failures of the national innovation system. The most relevant failures of Estonian national innovation system inhibiting the new product development are capability and networking failures. The sources of innovation of high-technology firms are too narrow, linkages with domestic firms and higher education institutions as well with foreign firms are poorly developed. High-tech firms have also serious capacity problems due to the extremely weak support mechanism by national innovation system on the seed funding stage of product development and prototype building stage as well. Paper argues that resources needed for the innovation should not be looked too narrowly following linear innovation model approach. Instead interactive approach is needed, which combines capability building, network development, interactive learning with direct investments into fundamental research.

    The pharmacopoeial quality of non-expired and expired nifedipine tablets of the same batches purchased from the Estonian and Russian Federation medicinal product markets was evaluated. The IR spectroscopy, HPLC analysis for quantitative content and purity of the active pharmaceutical ingredient (API), and dissolution test techniques were applied. In the experiments with non-expired nifedipine tablets, in all Estonian (n = 8, label claims 10, 20, and 40 mg) and Russian Federation (n = 4, label claim 10 mg) registered formulations the API was identified and quantified as nifedipine in amounts set by the European Pharmacopoeia and without exceeding the tolerance limits for the impurities. The dissolution rate was variable but all 10 and 20 mg non-expired nifedipine tablets released at least 80% of API in 12 h. The expiration of the nifedipine tablets led to somewhat increased dissolution rate while only traces of the nifedipine degradation products were discovered in the dissolution medium. In conclusion, our present study shows that with minor variations the Estonian and Russian Federation registered nifedipine tablets are comparable, the API preserves well beyond the expiration date but the expired nifedipine tablets may release the API faster than the non-expired tablets.

    Considerable levels of radium were detected in a certain fraction of the Estonian drinking water supply network. Some of these waterworks have treatment systems for the removal of (mainly) iron and manganese from drinking water. Three of these waterworks and another one equipped with a radium removal pilot plant were examined, and a specific study was conducted in order to assess the environmental compatibility of effluents and residues produced in the plants. (226)Ra and (228)Ra activity concentrations were analysed in both liquid (backwash water) and solid (sand filter and sediment) materials to evaluate their compliance, from the radiological point of view, with current Estonian legislation and international technical documents that propose reference levels for radium in effluents and residues. Also with regard to water treatment by-products, a preliminary analysis was done of possible consequences of the transposition of the European Basic Safety Standards Draft into Estonian law. Radium removal efficiency was also tested in the same plants. Iron and manganese treatment plants turned out to be scarcely effective, whilst the radium mitigation pilot plant showed a promising performance.

    Due to their sensitivity to environmental change, penguins in Antarctica are widely used as bio-indicators in paleoclimatic research. On the basis of bio-element assemblages identified in four ornithogenic sediment profiles, we reconstructed the historical penguin population change at Cape Bird, Ross Island, for the past 1600 years. Clear succession of penguin population peaks were observed in different profiles at about 1400 AD, which suggested a high probability of migration within this reg...

  12. Competing connections between the Ross Ice Shelf with the Southern Ocean.

    Science.gov (United States)

    Jendersie, Stefan

    2016-04-01

    The stability of the Ross Ice Shelf (RIS) is critical to both the East Antarctic Ice Sheet, and the West Antarctic Ice Sheet. Results from a climatological ice shelf-ocean coupled numerical model (ROMS) suggest a new circulation mechanism associated with High Salinity Water (HSSW) production in the Ross Sea Polynya (RSP) that controls oceanic heat access to the RIS cavity. Within the RSP the dense water-saturated water column contracts during winter and causes a seasonal drop in Sea Surface Height (SSH) localised to a convection chimney under the RSP. The SSH gradients of up to 1.5 mm per km are sufficient to generate a barotropic pressure gradient that can counteract the wide scale horizontal baroclinic force and reverse the geostrophic circulation. In water depths between 600 and 800 m north of the western RIS the effect causes the seasonal occurrence of a cyclonic circulation cell with transports greater than 1Sv. Appearing with the beginning of winter sea ice formation in the RSP it significantly changes the dynamics at the ice shelf front. The new mechanism is described as one element in a framework of oceanographic processes that mitigate the exchange between the deep ocean and the ocean cavity under the RIS. Our study links local circulation features that are known from observation and previous model studies, and for the first time establishes a coherent system of responsible physical forcing processes in the Ross Sea.​

    Three stations near the calving front of the Ross Ice Shelf, Antarctica, recorded GPS data through a full spring-neap tidal cycle in November 2005. The data revealed a diurnal horizontal motion that varied both along and transverse to the long-term average velocity direction, similar to tidal signals observed in other ice shelves and ice streams. Based on its periodicity, it was hypothesized that the signal represents a flow response of the Ross Ice Shelf to the diurnal tides of the Ross Sea. To assess the influence of the tide on the ice-shelf motion, two hypotheses were developed. The first addressed the direct response of the ice shelf to tidal forcing, such as forces due to sea-surface slopes or forces due to sub-ice-shelf currents. The second involved the indirect response of ice-shelf flow to the tidal signals observed in the ice streams that source the ice shelf. A finite-element model, based on viscous creep flow, was developed to test these hypotheses, but succeeded only in falsifying both hypotheses, i.e. showing that direct tidal effects produce too small a response, and indirect tidal effects produce a response that is not smooth in time. This nullification suggests that a combination of viscous and elastic deformation is required to explain the observations.

    High-resolution geophysical and geologic data were acquired in western and central Ross Sea, Antarctica, to determine the: (1) maximum extent and configuration of the ice sheet during the Last Glacial Maximum (LGM); (2) conditions and processes at the base of the expanded ice sheet and their role in ice stream activity; and (3) relative retreat history of the ice sheet. This information can provide geologic constraints for modeling of ice-sheet retreat. The research formed the basis for development of a public Web site (http://www.glacier.rice.edu) and for middle-school earth-science instructional materials. Based on identification of isolated grounding-zone wedges and consistency of mega-scale glacial lineations, the LGM ice edge reached the Coulman Island region in western Ross Sea. The maximum extent in central Ross Sea occurred at the continental-shelf edge, based on the presence of mega-scale glacial lineations, glacio-tectonic features, and shelf-edge gullies. Streaming ice, overlying a deforming bed typically catastrophic collapse of the ice sheet.

    In this study, current meter and hydrological data obtained during the X Italian Expedition in the Ross Sea (CLIMA Project) are analyzed. Our data show a nice agreement with previous data referring to the water masses present in this area and their dynamics. Here, they are used to further analyze the mixing and deepening processes of Deep Ice Shelf Water (DISW) over the northern shelf break of the Ross Sea. In more detail, our work is focused on the elementary mechanisms that are the most efficient in removing dense water from the shelf: either classical mixing effects or density currents that interact with some topographic irregularity in order to drop to deeper levels, or also the variability of the Antarctic Circumpolar Current (ACC) which, in its meandering, can push the dense water off the shelf, thus interrupting its geostrophic flow. We also discuss in detail the (partial) evidence of dramatic interactions of the dense water with bottom particulate, of geological or biological origin, thus generating impulsive or quasi-steady density-turbidity currents. This complex interaction allows one to consider bottom particular and dense water as a unique self-interacting system. In synthesis, this is a first tentative analysis of the effect of bottom particulate on the dense water dynamics in the Ross Sea.

    The 0-200 m surface layer of the Ross Sea was studied during summer 2014 to investigate the lability of the particulate organic matter (POM) in response to physical parameters. With the use of satellite information, we selected three zones, characterised by different physical setting: a northern offshore area, crossing the summer-polynya area of the Ross Sea (hereafter called ROME 1), a more coastal area next to the Terra Nova Bay polynya (ROME 2); a southern offshore area, towards the Ross Ice Shelf (ROME 3). Ice-maps showed that the seasonal ice retreat had already occurred in early December for most of the stations. Statistical analysis of the quantitative and qualitative characteristics of the POM pointed to significant differences between the stations, especially in the upper mixed layer (UML). A comparison with previous studies showed that the localised pulses of POM accumulation in the UML were similar to those recorded at the highly productive marginal ice zones, providing notable trophic support to the ecosystem. The UML, although rather thin and easily subjected to alterations, confirmed its pivotal role in the ecosystem dynamics. A POM quality favourable to consumers was highlighted at several stations in ROME 1 and ROME 3. Reduced trophic support was, instead, found in ROME 2. Limited POM consumption where deep-water formation takes place would increase the POM role in the transfer of C to the depths.

    Sea ice is an integral component of the polar climate system, constraining the effect of changing surface albedo, ocean-atmosphere heat exchanges, the formation of deep and intermediate waters that participate in driving the meridional overturning circulation and thus global climate. In recent years, a mono-unsaturated highly branched isoprenoid (HBI) alkene which is biosynthesised by certain sea ice diatoms during the spring bloom and, upon ice melt, deposited into underlying sediments, has been uniquely observed in Arctic sea ice and in Arctic sediments. Hence, the term IP25 (ice proxy with 25 carbon atoms) was proposed to distinguish this compound from other HBI isomers and has become an established proxy for the reconstruction of Arctic sea ice. In contrast, a monounsaturated HBI alkene, i.e. IP25, has not been observed in sea ice or sediments from the Antarctic. Hence, the application of diene and triene HBI concentrations and the resulting diene/triene (D/T) ratio was alternatively introduced as sea ice/open water indicators in the Southern Ocean. However, there is still lack of data covering the wide areas around the Antarctic, especially from the Ross Sea. Hence, we investigated surface sediment samples from the Ross Sea (n=14) collected during the R/V ARAON cruise in 2015 as well as from the Antarctic Peninsula (n=17) collected during several R/V ARAON cruises between 2001 and 2013. We will present our preliminary results and will discuss the applicability of the HBI in the Ross Sea.

    Subglacial Lake Whillans is located beneath the Whillans Ice Stream in West Antarctica. The lake is situated beneath 800 m of ice and ~ 70 km upstream of the grounding line where Whillans Ice Stream terminates into the Ross Sea. Subglacial Lake Whillans is a shallow lake and a component of a complex subglacial hydrological system that may resemble a large wetland along the Siple Coast of West Antarctica. Subglacial Lake Whillans drains and refills on a sub-decadal time scale discharging water towards the Ross Sea. Water and sediment samples were recovered from the lake, using clean access drilling technologies, in January, 2013. Isotopic analysis of the lake waters indicates basal meltwater from the ice sheet as the dominant water source. Geochemical analysis of the lake water reveals it is freshwater with mineral weathering as a significant solute source, with a minor contribution from sea water likely from relict marine sediments. Subglacial hydrothermal activity upstream may also contribute solutes. Nutrients N and P are present at micromolar concentrations. Sediment porewaters from shallow cores (~ 40 cm depth) of the subglacial lake sediments indicate increasing solute concentration with depth, with up to ~ five times greater solute concentrations than in the lake water. The waters and sediment contain metabolically active organisms which are likely involved in elemental cycling within the lake system. Here we will discuss solute sources to the lake, solute dynamics within the lake waters and sediment, and the fluxes of solute and nutrients to the Ross Sea and their implications for these marine ecosystems.

    An interdisciplinary team of researchers will focus on describing the high productivity patchiness observed in phytoplankton blooms in the mid-to-late summer in the Ross Sea, Antarctica. They will use a novel sampling strategy that employs a remotely controlled glider (AUV) to locate and map circumpolar deep water in near real time and also to direct further ship-based sampling. This unusual coordination of a polar research vessel with AUVs provides an exciting opportunity to engage formal and informal educators in a research adventure. As part of this NSF-funded project’s Criterion 2 broader impact, joining the researchers virtually will be 30 New Jersey middle-school teachers and their students. This summer in New Jersey, in partnership with Liberty Science Center educators, COSEE-NOW (Centers for Ocean Sciences Education Excellence-Networked Ocean World) and Woods Hole Oceanographic Institution, the project team introduced teachers to the Ross Sea, the research, the science behind it and the AUV. The summer workshop and ongoing schoolyear support is providing the teachers with the tools they need to bring the excitement of the research into their classrooms in real time during the Ross Sea cruise at the end of this year. This presentation by Chris Parsons, the project evaluator, will summarize the evaluation plan for this broader impact project, which follows teachers and their classes for a year, and provide the latest evaluation results from this project.

    Full Text Available The article discusses three Estonian translations of Daniel Defoe’s Robinson Crusoe into Estonian with the focus on the completeness of the translated texts and the characterisation given to these in paratextual information. While there are several translations and versions of the tex t available in E stonian that have either used a mediating language or do not proceed directly from Defoe’s novel, three editions explicitly list Defoe’s English-language Robinson Crusoe as their source text. These are Rudolf Sirge’s translation from 1950 and two editions translated by Valter Rummel that appeared in 1984 (reprinted in 2001 and 2007, respectively. The article sets out to discover the main differences between the three editions and the possible reasons that may have triggered their publication in Estonia at those particular times. In order to approach the issues, a general framework derived from descriptive translation studies is employed with an emphasis on Gideon Toury’s chrestomatic treatment of translation norms. Thus an attempt is made to detect the preliminary translational norms regarding translation policy, particularly the choice of texts to be translated, as well as the matricial norms that concern the fullness of the translated text and are part of operational norms manifested in the translator’s decisions which, in two of the cases at hand, may also have been decisions made by the editor or the censor. Rudolf Sirge’s translation appeared at a time when Estonia had fairly recently been incorporated into the Soviet Union and there was a lack of children’s literature ideologically appreciated by the regime. This may account for the packaging of the book as a work with a strong didactic bent, while its primary audience was taken to be children and young adults for whom the protagonist served as an example of a hard-working and tenacious hero to be emulated by young Soviets.

    Despite warming trends in global temperatures, sea ice extent in the southern hemisphere has shown an increasing trend over recent decades. Wind-driven sea ice export from coastal polynyas is an important source of sea ice production. Areas of major polynyas in the Ross Sea, the region with largest increase in sea ice extent, have been suggested to produce the vast amount of the sea ice in the region. We investigate the impacts of strong wind events on polynyas and the subsequent sea ice production. We utilize Bootstrap sea ice concentration (SIC) measurements derived from satellite based, Special Sensor Microwave Imager (SSM/I) brightness temperature images. These are compared with surface wind measurements made by automatic weather stations of the University of Wisconsin-Madison Antarctic Meteorology Program. Our analysis focusses on the winter period defined as 1st April to 1st November in this study. Wind data was used to classify each day into characteristic regimes based on the change of wind speed. For each regime, a composite of SIC anomaly was formed for the Ross Sea region. We found that persistent weak winds near the edge of the Ross Ice Shelf are generally associated with positive SIC anomalies in the Ross Sea polynya area (RSP). Conversely we found negative SIC anomalies in this area during persistent strong winds. By analyzing sea ice motion vectors derived from SSM/I brightness temperatures, we find significant sea ice motion anomalies throughout the Ross Sea during strong wind events. These anomalies persist for several days after the strong wing event. Strong, negative correlations are found between SIC within the RSP and wind speed indicating that strong winds cause significant advection of sea ice in the RSP. This rapid decrease in SIC is followed by a more gradual recovery in SIC. This increase occurs on a time scale greater than the average persistence of strong wind events and the resulting Sea ice motion anomalies, highlighting the production

Our main aim is to explore whether the factors that explain the choice of particular determiner forms are similar in Estonian and Finnish. We use a picture-sequence based elicitation experiment to collect spoken narratives from adult native speakers of Estonian and Finnish, and apply non-parametric tree and forest models to analyze the data. Our findings indicate that number of mention and animacy are important predictor variables in both languages, but their exact effect is divergent. We also find that in Finnish, case of the determiner NP proves to be an important factor, while in Estonian, syntactic role of the NP explains some aspects of determiner form choice. Nevertheless, the overall usage frequency of determiners is modest in the Estonian and Finnish data, and the process of grammaticalizing articles is only in initial stages in both languages. *** Artikliga, artiklita?

    The Ross procedure has become the first choice for aortic valve replacement in children and young adults at many institutions. Since 1997, a lack of availability of homograft valves in Turkey has prompted the use of alternative substitutes for right ventricular outflow tract (RVOT) reconstruction during the Ross procedure. Before April 2005, among 20 patients (age range: 14 months to 45 years) at the present authors' institution, the Ross procedure was performed in 14 and a Ross-Konno procedure in six. Sixteen patients underwent RVOT repair using alternative methods for homograft valve replacement. Fourteen patients received a Medtronic Freestyle valve and one patient a Medtronic Contegra bovine jugular vein conduit. An autologous RVOT repair was used in one patient. Ten of the Medtronic Freestyle valve patients were aged Medtronic Freestyle valve echocardiographic evaluations were conducted shortly after surgery and during follow up. There was no early mortality. One patient died from pneumonia after six months, and another (asymptomatic) patient died suddenly at 34 months after surgery. Before hospital discharge the mean peak pressure gradient across the Freestyle valve was 12.1 +/- 11.0 mmHg, and this increased to 24.1 +/- 20.0 mmHg after a mean follow up of 51.2 +/- 6.9 months (range: 6 to 101 months) (p Medtronic Freestyle valve, the present results show that the valve can be used with intermediate-term success in the Ross procedure - and even in children as an alternative - if homograft valves are not available.

    We have adopted gridded products describing surface elevation, ice-thickness and the sea floor and subglacial bed elevation south of 60◦ S from Bedmap2 and north of 60◦ S from JGP95E to calculate Bouguer and isostatic gravity anomaly of the Ross Sea region based on the DTU10 free-air gravity anomaly.Taking a view of the free-air, Bouguer and isostatic gravity anomalies, it is unusual that high values overlay the Victoria Land Basin, Central Trough, Northern Basin and Northern Central Trough while basement highs are associated with low value. A number of studies have attributed the high gravity anomalies across the depocenters to high-density volcanics deep within the basins or magmatic intrusions within the region of the thinned crust or upper mantle (e. g., Edwards et al., 1987). According to the conclusion from Karner et al. (2005), the anticorrelation of gravity anomalies with sediment basement can be reproduced if the flexural strength of the lithosphere during the late Cretaceous rifting is significantly lower than the flexural strength of the lithosphere at the Oligocene and Neogene time of sedimentation. We note that the isostatic gravity anomalies are higher than the free-air gravity anomalies adjacent to the Transantarctic Mountains, and vice versa away from the Transantarctic Mountains. We may ignore the constraints offered by the tranditional isostasy in the local gravity studies of the Ross Sea basins, especially advancing the concept of high density material in the lower crust or upper mantle. In particular, the modeled gravity does not laterally integrate to zero, due to the existence of unbalanced forces induced by mantle. Along the outer shelf uplift zone surrouding Antarctica, the positive gravity belt has higher values in free-air gravity anomalies than those in isostatic gravity anomalies. Meanwhile, the positive gravity belt of isostatic gravity anomalies almost disappears in the background anomalies of 20 mGal to 10 mGal facing the

    The injection of Ar into the region of the DIII-D divertor is a promising technique for energy dissipation (through radiation and collisions) and consequently for reduction of the heat load on the plates. An important problem related to this technique, is the inherent poisoning of the core plasma by migrating Ar. The Ar core contamination seems also to improve the thermal transport in an advanced operating mode of the tokamak. It is therefore of great importance to measure the evolution of the impurity concentration profile within the core plasma. This goal could be achieved by using the Ross filter method in conjunction with the existing x-ray diagnostics on DIII-D. A basic Ross filter system consists of two identical detectors placed behind two different x-ray absorbing foils looking at the same plasma volume. The foils are made of different elements or compounds with adjacent or nearly adjacent atomic numbers. Their accurate thickness causes the x-ray transmission curves of the two foils to be effectively identical over the entire energy range except within the narrow region between their absorption edges. Since the transmission characteristics of the foils above and below their absorption edges are the same, any difference in the two detected signals is proportional to the total x-ray power of the emission spectrum between these two edge energies. An x-ray Ross filter with its energy pass band centered on the Ar XVII Kα line at 3.14 keV has been designed. This allows for the discrimination of the Ar Kα line only, regardless of Ar ionization state, against any background radiation with energies outside the energy pass band. The Ross filter was installed in front of two of the fan shaped poloidal x-ray arrays on DIII-D. The first measurements showed very good discrimination against Ne, another injected impurity. Emissivity profile evolution of the Kα lines and Ar enhanced continuum within the energy pass band of the Ross filter can be determined from the x

    The natural environment of Estonia is sensitive to climate change due to its location in a transitional zone between areas with different bioclimatic conditions. We studied the NAO index and data on temperature, moisture, wind, and sea level regimes in Estonia and the Baltic Sea region. We also looked at the relationships between meteorological forcing time series and changes in wetlands. The effects of changing climatic conditions are clearly reflected in the data from the station at Tooma mire, where we identified shorter snow-cover duration, decreased soil-frost depth and changed groundwater levels in the bog. In comparing various types of Estonian wetlands under such changing climatic conditions, we also identified greater instability in the character of coastal wetlands compared to that of the inland bogs. We found that the most marked coastal changes in Estonia result from a combination of strong storms, high sea levels induced by storm surge, ice free seas and unfrozen sediments. Finally, we also found that a significant trend in the development of seashore grasslands is the replacement of former meadows by reed beds, shrubberies or woodland. (orig.)

    Eimeria and Cryptosporidium are among the most common bovine parasites in the world, but little is known about them in Estonia. Basic field research is needed to gain insight into pathogen dynamics, providing knowledge for veterinarians and research. A survey of 45 Estonian dairy farms in 15 counties was carried out between 2006 and 2007. Three age groups: 12 months old animals were sampled. Collected faeces were examined by quantitative flotation and Ziehl-Neelsen contrast staining, and species examined morphologically. Selected samples containing Cryptosporidium were additionally examined by polymerase-chain-reaction (PCR) and sequencing to determine genotypes. Twelve species of Eimeria were identified, seven previously unknown in Estonia. Main species in samples were E. bovis (30%), E. zuernii (23%), and E. ellipsoidalis (14%). All herds were infected and animals aged 3-12 months were more commonly infected with Eimeria oocysts (63%) than any other group. Calves Eimeria and the age category. Cryptosporidium were detected in 84% of the farms, and C. andersoni and C. parvum were successfully identified. Though prevalences of Cryptosporidium in the age groups were similar to the sample prevalence (30%) an increase in the infections was found with increasing age (pEimeria spp. infection (slope=-0.08, pEimeria species.

    In the Republic of Estonia, local low-grade carbonaceous fossil fuel--Estonian oil-shale--is used as a primary energy source. Combustion of oil-shale is characterized by a high specific carbon emission factor (CEF). In Estonia, the power sector is the largest CO(2) emitter and is also a source of huge amounts of waste ash. Oil-shale has been burned by pulverized firing (PF) since 1959 and in circulating fluidized-bed combustors (CFBCs) since 2004-2005. Depending on the combustion technology, the ash contains a total of up to 30% free Ca-Mg oxides. In consequence, some amount of emitted CO(2) is bound by alkaline transportation water and by the ash during hydraulic transportation and open-air deposition. The goal of this study was to investigate the possibility of improving the extent of CO(2) capture using additional chemical and technological means, in particular the treatment of aqueous ash suspensions with model flue gases containing 10-15% CO(2). The results indicated that both types of ash (PF and CFBC) could be used as sorbents for CO(2) mineral sequestration. The amount of CO(2) captured averaged 60-65% of the carbonaceous CO(2) and 10-11% of the total CO(2) emissions.

Published research on condom use and types of contraceptives used yield mixed results, yet, the perception that military members are at higher risk for STIs remains. The objectives of this cross-sectional study were to measure factors such as condom use, contraceptive methods, and risky behaviours (i.e. drug use and sex with commercial sex workers) and investigate differences between ethnic groups, where culture could influence behaviour. Data were collected from a recruited population of 584 male, military conscripts in northeastern Europe. Using multinomial logistic regression models, statistically significant findings include an interaction between the use of contraceptive methods of Russians with casual partners and ethnicity, with higher odds of effective methods used among Estonians with regular partners (OR = 8.13) or casual partners (OR = 11.58) and Russians with regular partners (OR = 4.98). Effective contraceptive methods used less frequently with casual partners by ethnic Russians is important in providing education and risk reduction services to young, male conscripts. These findings may be used as a baseline to inform health education and STI prevention programmes tailored to military members in Eastern Europe in the absence of other published studies.

    To study help-seeking among the general population and people with major depression. 12-month help-seeking for emotional problems was assessed in a cross-sectional 2006 Estonian Health Survey. Non-institutionalized individuals aged 18-84 years (n = 6,105) were interviewed. A major depressive episode was assessed using the Mini-International Neuropsychiatric Interview. The factors associated with help-seeking, received help, and health service use were analyzed. The prevalence of 12-month help-seeking for emotional symptoms was 4.8%. The rate of 12-month help-seeking in the depressed sample was 34.1%. Depressed people used non-mental health services 1.5-3 times more than non-depressed persons even when adjusted for the chronic somatic disorder. Only one third of depressed persons sought help, which was most of all associated with severity of depression. Underdiagnosis and undertreatment of depression leads to an increased use of expensive but non-specific health services by depressed persons.

    Full Text Available Family businesses have a remarkable role in the world economy; their role in economies has been investigated by many researchers. This paper seeks to study the findings of research conducted over 2008…2011 in Estonia in the field of family businesses and family business entrepreneurs. This research attempts to define development and sustainability of family businesses in Estonian economy. After Estonia regained independence in 1991, private entrepreneurship started to develop, and many people, particularly in rural areas, set up a family enterprise. After Estonia’s accession to the European Union in 2004, family business activity boosted further still. Until 2007, family business activity was rather domestic market focused; after Estonia was acceded to the Schengen visa area, they started to successfully sell products and services outside Estonia. The research findings can be used either for diversifying economic activity of family businesses or for investment support or in other areas. This research definitely benefits to all enterprising people who wish to become a family business entrepreneur and who wish to set up a strong and sustainable family business

  15. Frost related dieback in Estonian energy plantations of willows in relation to fertilisation and pathogenic bacteria

    Two 9-year old Estonian Salix plantations suffering from dieback were studied: one situated on poor mineral soil and divided into fertilised and unfertilised plots (Saare plantation) and another growing on a well-decomposed and nitrogen-rich organic soil, without fertiliser application (Kambja plantation). Bacteria from internal tissues of visually damaged shoots from seven clones were isolated in spring and autumn. The strains were subsequently biochemically characterised and tested for ice nucleation activity and pathogenicity on Salix. Some strains were also analysed with 16S rRNA. High numbers of culturable bacteria were found, belonging mainly to Erwinia, Sphingomonas, Pseudomonas and Xanthomonas spp. Fertilised plots were significantly more colonised by bacteria than unfertilised plots and also more extensively damaged, showing a lower density of living plants after 7 years of culture. More ice nucleation active (INA) strains were found in Saare fertilised plots and at Kambja than in Saare unfertilised plots. Likewise, most pathogenic strains were isolated from Saare fertilised plots and from Kambja. For some of the willow clones studied, dieback appeared to be related to both clonal frost sensitivity and abundance of INA and pathogenic bacteria. The plantations probably suffered from the presence of high amounts of pathogens and from frost related injuries aggravated by INA bacteria. Most probably the fertilisation at Saare and the nitrogen-rich soil at Kambja created a favourable environment for bacterial development and led to high dieback levels after the first harvest.

    A two-year seismometer deployment on various icebergs in the Ross Sea and on the Ross Ice Shelf (PASSCAL project SOUTHBERG) have produced an unusual seismological "tone poem" constituting a sample of ambient conditions in an iceberg-covered, coastal sea of Antarctica. The original motivation of the project was to investigate the source of signals seen as T-phases in the equatorial Pacific [e.g., Talandier et al., 2002]. During the periods of continuous seismometer operation (i.e., during the October - April periods of 2003-4 and 2004-5 when photovoltaic charging systems kept seismometers in operation) on icebergs B15A, C16 and Nascent Iceberg (a site not yet calved from the Ross Ice Shelf), about 1300 events were observed (roughly one event per day). These events are attributed to the icebergs, and are loosely referred to as "iceberg tremor" due to their long duration (many hours) and spectral structure (e.g., characterized by clearly preferential frequencies in the 1-3 Hz range, accompanied by multiple harmonics of a variable-pitch fundamental). The purpose of this presentation is to give a general qualitative overview of the various categories of iceberg tremor, and to describe their relationship to other variables observed (e.g., iceberg drift velocity, iceberg-on-iceberg collision, iceberg-on-seabed scraping). Speculation on the cause or causes of iceberg tremor will be postponed pending further study. Suggestions as to the relationship between the ambient tone poem of iceberg-covered waters and hydro-acoustic and seismic signals seen in the ocean beyond Antarctica will be offered.

    The James Ross Island ice core, drilled to 364 m on the northern tip of the Antarctic Peninsula, preserves a climate record that spans beyond the Holocene period to the end of the last glacial maximum (LGM). Reanalysis of the ice core using high-resolution continuous flow analysis (CFA) highlighted errors in the identification of events of known age that had been used to constrain the earlier chronology. The new JRI2 chronology is annual layer counted to 300 years, with the remaining profile reconstructed using a new age-depth model that is tied to age horizons identified in the annual-layer counted WAIS Divide ice core record. An accurate age-depth profile requires reliable known-age horizons along the ice core profile. In addition, these allow us to determine a solution for the accumulation history and rate of compaction due to vertical strain. The accuracy of the known-age constraints used in JRI2 allows only a small uncertainty in the reconstruction of the most recent 2000 years of accumulation variability. Independently, the surface temperature profile has been estimated from the stable water isotope profile and calibrated to borehole temperature observations. We present the accumulation, vertical thinning and temperature history interpreted from the James Ross Island ice core for the most recent 2000 years. JRI2 reconstructions show accumulation variability on a decadal to centennial timescale up to 20% from the present-day mean annual accumulation rate of 0.63 m yr-1. Analysis of the accumulation profile for James Ross Island offers insight into the sensitivity of accumulation to a change in surface temperature, as well as the reliability of the assumed relationship between accumulation and surface temperature in climate reconstructions using stable water isotope proxies.

    Referring to the fundamental question in ecosystem research, how biotic and abiotic processes interact, only a few studies exist for polar regions that integrate microbiological and soil scientific studies . Soils comprise the complex structure and environment that fosters water storage and nutrient cycling determined by its unique chemical, physical and biological properties with respect to the specific climate and parent material. In the extreme environment of Antarctica, soil biological processes are primarily controlled by microbial communities (Bacteria, Archaea and Fungi), and thus microbiota may also determine soils chemical and physical properties in a landscape lacking higher plants at an average air temperature below 0°C. James Ross Island, Maritime Antarctica, offers a pristine laboratory and an exceptional opportunity to study pedogenesis without the influence of vascular plants and burrowing animals. We analysed micromorphological features, chemical and microbiological measures at two sites on James Ross Island (Brandy Bay and St. Martha Cove) with similar substrates (mostly fine-grained calcareous sandstones and siltstones of the Alpha Member of the Santa Martha Formation with varying amounts of conglomerates and mudstones) at similar topographic positions (small plateaus at similar elevation (80m a.s.l.)). The sites represent luv- and leeward conditions with respect to the main southwesterly winds. The climate on James Ross Island is to be described as semi-arid polar-continental, which is in clear contrast to the Southern Shetlands (e.g. King George Island) north of the Antarctic Peninsula. We will present first results of soil physical (bulk density, soil moisture and grains size distribution), pedochemical (SOC, total N and S, pH, CECeff, and pedogenic oxides) micromorphological and microbial analyses (Microbial DNA content, microbial abundances).

    Fracture geometries in the Ross Ice Shelf, observable using visible band satellite imagery from the MODIS Mosaic of Antarctica (MOA) and the Landsat Image Mosaic of Antarctica (LIMA) provide a unique opportunity to study fracture propagation behavior and discharge variability in the ice streams and outlet glaciers feeding the shelf. Propagation is driven by changes in fracture length, near-field stress conditions, and the material properties of the ice. Changes in ice stream discharge and the development of "sticky spots," in both ice streams and within the shelf, lead to redirection of flow, changes in lateral gradients of ice velocity, and the propagation of fractures in response to changes in near-field stresses. The propagation behaviors most commonly observed in the ice shelf are the growth in the transverse direction of a fracture that formed within a shear zone and mechanical interactions between adjacent fracture tips. We use fracture mechanics theory and remote-sensed imagery to categorize fracture patterns and longitudinal zones of fractured ice in the Ross Ice Shelf. Near current sites of formation, simple fracture geometries and principal stresses are used to illustrate physical processes related to the formation and propagation of fractures. To compute flow lines and principal stresses, we derive a velocity map of the Ross Ice Shelf by merging two velocity datasets using a combination of statistical methods. A structural map of fracture geometries, relict shear margins, and structural boundaries is constructed. Using the ice shelf features, present-day flow lines, and principal stresses, we investigate the manner in which principal stresses affect fracture formation and propagation behavior and the variability of ice stream discharge into the shelf.

  20. The relevance of buttressing for Filchner-Ronne and Ross Ice Shelf

    Sub-shelf melting is an important component of Antarctica's mass budget. Although thinning of ice shelves does not directly contribute to sea-level rise, it may have a significant indirect impact through the potential of ice shelves to buttress their adjacent ice sheet. This is clearly seen in recent observations, e.g. in the Amundsen region (Pritchard et al., 2012) or at the Southern Antarctic Peninsula (Wouters et al, 2015) where increased ice loss of the adjacent upstream drainage basins is attributed to enhanced sub-shelf melting. In the extreme case, the complete disintegration of an ice shelf, e.g. during the calving events of Larsen A and B in 1995 and 2002, respectively, the adjacent ice streams subsequently accelerated significantly (Scambos et al., 2014). Here, we investigate the importance of buttressing using the finite-element, shallow-stream approximation numerical model Úa. We derive transfer functions for an idealized setup (Gudmundsson et al. 2012) and the Filchner-Ronne and Ross Ice Shelf. They allow for the computation of instantaneous changes in velocities to thickness perturbation patterns. Based on the transfer functions, we calculate the sensitivity of flux across the grounding line to regional varying melting patterns for the idealized setup and for Filchner-Ronne and Ross Ice Shelf. We find that the immediate response of velocities in the ice shelf-ice sheet system to changes in sub-shelf melting can be understood as the interaction of two effects: On the one hand, the spreading rate is a function of local ice thickness, indicating that a thinning of the ice shelf reduces velocities. On the other hand, ice shelf thinning weakens its ability to buttress, and thus enhances velocities. These two processes compete, leading to a complex pattern of velocity changes within the ice shelf. We find - both in the idealized setup and for Ross and Filchner-Ronne Ice Shelves - that the reduction in buttressing is dominating the velocity changes in the

    The diet of Antarctic silverfish Pleuragramma antarcticum was evaluated by examining stomach contents of specimens collected in the Ross Sea (71°-77° S; 165°-180° E) in January to March 2008. Pleuragramma antarcticum (50-236 mm standard length, L(S)) and prey items were analysed for stable-isotopic composition of carbon and nitrogen. According to index of relative importance (I(RI) ), which incorporates frequency of occurrence, mass and number of prey items, the most important prey items were copepods (81%I(RI) over all specimens), predominantly Metridia gerlachei and Paraeuchaeta sp., with krill and fishes having low I(RI) (2·2 and 5·6%I(RI) overall). According to mass of prey (M) in stomachs, however, fishes (P. antarcticum and myctophids) and krill dominated overall diet (48 and 22%M, respectively), with copepods being a relatively minor constituent of overall diet by mass (9·9%M). Piscivory by P. antarcticum occurred mainly in the extreme south-west of the region and near the continental slope. Krill identified to species level in P. antarcticum stomachs were predominantly Euphausia superba (14·1%M) with some Euphausia crystallophorias (4·8%M). Both DistLM modelling (PRIMER-permanova+) on stomach contents (by I(RI)) and stepwise generalized linear modelling on stable isotopes showed that L(S) and location were significant predictors of P. antarcticum diet. Postlarval P. antarcticum (50-89 mm L(S)) consumed exclusively copepods. Juvenile P. antarcticum (90-151 mm L(S)) consumed predominantly krill and copepods by mass (46 and 30%M, respectively). Small adult P. antarcticum (152-178 mm L(S)) consumed krill, fishes and copepods (37, 36 and 15%M, respectively). Large adult P. antarcticum (179-236 mm L(S)) consumed predominantly fishes and krill (55 and 17%M, respectively), especially in the north (near the Ross Sea slope) and in the SW Ross Sea. Amphipods were occasionally important prey items for P. antarcticum (western Ross Sea, 39%M). General

    2001-11-01

    This paper elucidates and explains an ancient midrash (rabbinic interpretation of a biblical text) through the lens of modern psychological theory. The midrash describes Moses' reactions to his approaching death. The paper points out that these reactions anticipate the five classic stages, described by Elizabeth Kubler-Ross, of coming to accept terminal illness: denial, anger, bargaining, depression and acceptance. The article shows the ancient rabbis' sensitivity to human feeling and the universal nature of human reaction through the dialogue and reactions they attribute to Moses. Finally, it shows how using this midrash offers a constructive model for approaching death, for Jewish and non-Jewish patients alike, as well as their caregivers.

    2013-06-01

    Full Text Available A distinctive feature of the (literary culture of the 2000s is a sudden increase in the publication of works of life writing in different genres. Although life writing as a phenomenon has received considerably more critical attention in recent years, it has not yet settled within the literary canon, and theoretical debates concerning its diverse textual practises are still in initial phases. The current article provides an overview of Estonian life writing of the 2000s, viewing the emergence of new forms, themes and perspectives as a continuity within the wider framework of the post-Soviet period and in comparison with some recent developments and theoretical foci of life writing studies in general.The processes of the construction of subjectivity and identity in a number of autobiographical writings published in the first half of the 2000s can be traced back to the emergence of Estonian “memorial culture” in the late 1980s and 1990s, where oral and written testimonial accounts of personal experience focusing on the period of the Soviet occupation played an important role in the process of dismantling the official Soviet discourses of history and contributed to the process of regaining independence. A number of life writing texts by well-known Estonian literary figures published in the mid-2000s employ modes of collective and individual self-conception and self-reflection similar to those prevalent in the texts of life stories. No longer employed for the purposes of implementing socio-political change, these works confirm and consolidate such modes of identification and self-representation within the framework of (literary culture. Another important trend of Estonian life writing of the 2000s involves “textual games”, where lived experience and the construction of fictional worlds are intertwined in a complex and self-conscious manner. Visible most strongly in the work of Tõnu Õnnepalu and Madis Kõiv, this feature of Estonian life

    Full Text Available Changes in the Estonian National Museum from 1909 to the presentThe Estonian National Museum was founded in Tartu in 1909 as part of the national movement. With its activities and connections in society, the ENM helped create Estonian society, the nation’s collective memory and identity.The ENM has always been – despite the changing locations, names, and content – one of the symbols of national identity. But at the same time, ENM has never had its own building designed specially for the museum’s purposes.Since 1909 there have been several attempts to establish a home for the ENM. At first (1909–1923, Estonian society wanted to establish the museum in the center of Tartu. The museum was intended to become a key institution of the growing nation and establishing the nation’s identity.At last in 1923 the ENM secured the Raadi manor, outside the center of the city, in a beautiful park, near the lake with its boats and water attractions. In this manor the first permanent exhibition of mainly 19th century Estonian peasant life was compiled, and the ENM operated in the Raadi manor from 1923–1940 as the “Estonian’s own museum” The years of alternating occupations, World War II, and political terror damaged and destroyed the whole society. The Raadi manor was destroyed in the war too, and the ENM itself was divided into two parts – the State Ethnographic Museum and the State Literary Museum. The collections of the ENM were given to Tallinn and to many different places inside and outside Tartu. Then began “the period of temporary location” that continues today. The museum is located in several places in the city of Tartu.In 1988, the prior name of the State Ethnographic Museum – the Estonian National Museum – was reinstated. Since the 1990s there have been many attempts to secure a special building for the ENM. Now, at last, as a result of serious economic pressure, we are closer to this goal than ever. During the last five

    The Ross Sea is critically important in regulating Antarctic sea ice and is biologically productive, which makes changes in the region's physical environment of global concern. We examined the effects of projected changes in atmospheric temperatures and winds on aspects of the ocean circulation likely important to primary production using a high-resolution sea ice-ocean-ice shelf model of the Ross Sea. The modeled summer sea-ice concentrations decreased by 56% by 2050 and 78% by 2100. The duration of shallow mixed layers over the continental shelf increased by 8.5 and 19.2 days in 2050 and 2100, and the mean summer mixed layer depths decreased by 12 and 44%. These results suggest that the annual phytoplankton production in the future will increase and become more diatomaceous. Other components of the Ross Sea food web will likely be severely disrupted, creating significant but unpredictable impacts on the ocean's most pristine ecosystem.

    Full Text Available Measurements of total alkalinity (AT and pH were made in the Ross Sea in January–February 2008 in order to characterize the carbonate system in the Ross Sea and to evaluate the variability associated with different water masses. The main water masses of the Ross Sea, Antarctic Surface Water, High Salinity Shelf Water (HSSW, Deep Ice Shelf Water, Circumpolar Deep Water (CDW and Antarctic Bottom Water, were identified on the basis of the physical and chemical data. In particular, the AT ranged between 2275 and 2374 µmol kg−1 with the lowest values in the surface waters (2275–2346 µmol kg−1, where the influence of the sea-ice melting and of the variability of the physical properties was significant. In the deep layers of the water column, the AT maxima were measured in correspondence to the preferential pathways of the spreading HSSW. The pH had variable values in the surface layer (7.890–8.033 with the highest values in Terra Nova Bay and Ross Sea polynyas. A low pH (7.969±0.025 traced the intrusion of the CDW in the Ross Sea shelf area. All samples revealed waters that were oversaturated with respect to both calcite and aragonite, but near corrosive levels of aragonite saturation state (Ω ca. 1.1–1.2 were associated with the entrainment of CDW over the slope. Aragonite undersaturation is of particular concern for the zooplankton species comprising to calcifying organisms such as pteropods. The partial pressure of CO2 at the sea surface was undersaturated with respect to the atmospheric value, particularly in Terra Nova Bay and the Ross Sea polynyas, but a large variability in the sea–air CO2 fluxes was observed associated with different responses in the strength of the biological and physical processes.

Radiocarbon dates yield late Pleistocene (stage 3) ages for these deposits, hence the carbonates appear to be correlative with widespread tills and glacial marine deposits in the region. Four carbonate facies are recognized on the basis of skeletal composition: a barnacle/foraminifer facies, a muddy bryozoan facies, a bryozoan/barnacle/pelecypod/foraminifer facies, and a planktonic foraminiferal facies. These deposits occur on the shelf and upper slope, while carbonate turbidities derived from them occur on the adjacent continental slope and rise. Compositional analyses of Ross Sea carbonates lend support to previously recognized criteria for identifying cold water carbonates. These include: (1) the presence of an associated ice-rafted component (including dropstones); (2) a dominance of calcite relative to other carbonate minerals (the remaining fraction consists solely of aragonite); (3) allochems that are entirely skeletal; and (4) heavy oxygen isotopic compositions (in the range of +3.0 to +5.1% PDB).

    Krill, a key pelagic resource of the Antarctic food web, provides an important link between primary and secondary plankton production and top predators. Since krill abundance is a crucial factor in Antarctic ecosystem functioning, its monitoring supplies vital data. Acoustic surveys are an effective approach to estimating krill abundance. An acoustic survey was conducted in the western Ross Sea in January 2014-10 years after a similar survey by our team - to estimate krill abundance and biomass and monitor oceanographic conditions. Antarctic krill (Euphausia superba) was detected in the northern part of the western Ross Sea and dense swarms of ice krill (Euphausia crystallorophias) were found in its central coastal area. Data analysis revealed an inverse correlation between E. superba density and salinity in the water column, whereas a positive correlation was found between E. crystallorophias abundance and fluorescence; the latter relationship was confirmed in thematic maps of E. crystallorophias spatial distribution and fluorescence. Comparison of 2004 and 2014 biomass data showed a much greater abundance of both species in the more recent survey.

    Full Text Available Background: Competition in the banking industry has been an important topic in the scientific literature as researchers tried to assess the level of competition in the banking sector. Objectives: This paper has an aim to investigate the market structure and a long term equilibrium of the banking market in Bosnia and Herzegovina nationwide as well as on its constitutional entities as well as to evaluate the monopoly power of banks during the years 2008-2012. Methods/Approach: The paper is examining the market structure using the most frequently applied measures of concentration k-bank concentration ratio (CRk and Herfindahl-Hirschman Index (HHI as well as evaluating the monopoly power of banks by employing Panzar-Rosse “H-statistic”. Results: The empirical results using CRk and HHI show that Bosnia and Herzegovina banking market has a moderately concentrated market with a concentration decreasing trend. The Panzar-Rosse “H-statistic” suggests that banks in Bosnia and Herzegovina operate under monopoly or monopolistic competition depending on the market segment. Conclusions: Banks operating on the banking market in Bosnia and Herzegovina seem to be earning their total and interest revenues under monopoly or perfectly collusive oligopoly.

    Full Text Available A present study was conducted to evaluate the effect of dietary inclusion of bee pollen extract on meat performance of Ross 308 broiler chickens. A total of 180 one day-old Ross chicks were involved in experiment. Chickens were divided into 2 groups, an experimental group (E and a control group (C. No added supplement was given to the control group, while the experimental group was given the feed mixture supplemented with bee pollen in an amount of 400 mg.kg-1, during the whole fattening period. Data of live body weight, carcass weight, giblets weight and carcass yield were determined at 42 days of the age. The supplementation of bee pollen increased final body weight of broilers by 68.5 g. Each of investigated parameters of meat performance in experimental group was higher to that in control group, although the difference among the groups was not statistically significant (P≥0.05. The addition of bee pollen at dose 400 mg.kg-1 in the feed mixture indicates the slight effect on meat performance of chickens which can be beneficial for fattening of broiler chickens.

    It is widely accepted that the West Antarctic Ice Sheet (WAIS) was grounded at the continental shelf edge in the eastern Ross Sea during the Last Glacial Maximum (LGM), but the precise chronology is debated. Post-LGM ice retreat chronologies have been developed using radiocarbon dating, mainly of acid-insoluble organics (AIO). Foraminifer tests yield more accurate radiocarbon dates than AIO because forams are less likely to be contaminated by allochthonous carbon, but unfortunately forams are sparse in Antarctic marine sediment cores. Here we show four consistent radiocarbon dates from forams in cored intervals within the foreset of a mid-continental-shelf grounding-zone wedge in Eastern Basin, Ross Sea. Our new radiocarbon dates reveal that the WAIS was grounded on the mid continental shelf circa 32,000 14C yr B.P., suggesting that retreat from this position began more than 10,000 years prior to the maximum sea level fall and global cooling associated with LGM. The dates contradict previous studies, which concluded that the WAIS was at its maximum shelf edge extent during LGM.

  1. Ross ice shelf cavity circulation, residence time, and melting: Results from a model of oceanic chlorofluorocarbons

    Despite their harmful effects in the upper atmosphere, anthropogenic chlorofluorocarbons dissolved in seawater are extremely useful for studying ocean circulation and ventilation, particularly in remote locations. Because they behave as a passive tracer in seawater, and their atmospheric concentrations are well-mixed, well-known, and have changed over time, they are ideal for gaining insight into the oceanographic characteristics of the isolated cavities found under Antarctic ice shelves, where direct observations are difficult to obtain. Here we present results from a modeling study of air-sea chlorofluorocarbon exchange and ocean circulation in the Ross Sea, Antarctica. We compare our model estimates of oceanic CFC-12 concentrations along an ice shelf edge transect to field data collected during three cruises spanning 16 yr. Our model produces chlorofluorocarbon concentrations that are quite similar to those measured in the field, both in magnitude and distribution, showing high values near the surface, decreasing with depth, and increasing over time. After validating modeled circulation and air-sea gas exchange through comparison of modeled temperature, salinity, and chlorofluorocarbons with field data, we estimate that the residence time of water in the Ross Ice Shelf cavity is approximately 2.2 yr and that basal melt rates for the ice shelf average 10 cm yr -1. The model predicts a seasonal signature to basal melting, with highest melt rates in the spring and also the fall.

    Although a number of active source seismic experiments have been conducted over the last few decades to investigate the crustal structure in the Ross Sea, Antarctica, long-term observation to monitor underwater tectonic activities and changes in the cryospheric environment still remains challenging due to existence of sea ice in the study region. Korea Polar Research Institute has accomplished successful deployment of ocean bottom seismometers (OBS) in the Ross Sea collaborating with Alfred Wegener Institute during the period of 2011-2012 and 2014 by Korean icebreaker RV Araon. The OBS system manufactured by K.U.M. contains a hydrophone sensor that allow us to monitor underwater acoustics generated by tectonic and ice-related events. We present spectrograms of the continuous hydroacoustic data and various types of signals, e.g. seismic T-waves, iceequakes, and tremors. There are periodic and harmonic tremors that might be related with tidal modulation, and the seasonal variation of the background noise seems to be related with sea ice concentration.

    In the context of global warming, the question of why Antarctic sea ice extent (SIE) has increased is one of the most fundamental unsolved mysteries. Although many mechanisms have been proposed, it is still unclear whether the increasing trend is anthropogenically originated or only caused by internal natural variability. In this study, we employ a new method where the underlying natural persistence in the Antarctic SIE can be correctly accounted for. We find that the Antarctic SIE is not simply short-term persistent as assumed in the standard significance analysis, but actually characterized by a combination of both short- and long-term persistence. By generating surrogate data with the same persistence properties, the SIE trends over Antarctica (as well as five sub-regions) are evaluated using Monte-Carlo simulations. It is found that the SIE trends over most sub-regions of Antarctica are not statistically significant. Only the SIE over Ross Sea has experienced a highly significant increasing trend (p = 0.008) which cannot be explained by natural variability. Influenced by the positive SIE trend over Ross Sea, the SIE over the entire Antarctica also increased over the past decades, but the trend is only at the edge of being significant (p = 0.034).

    The crew assigned to the STS-61B mission included Bryan D. O'Conner, pilot; Brewster H. Shaw, commander; Charles D. Walker, payload specialist; mission specialists Jerry L. Ross, Mary L. Cleave, and Sherwood C. Spring; and Rodolpho Neri Vela, payload specialist. Launched aboard the Space Shuttle Atlantis November 28, 1985 at 7:29:00 pm (EST), the STS-61B mission's primary payload included three communications satellites: MORELOS-B (Mexico); AUSSAT-2 (Australia); and SATCOM KU-2 (RCA Americom). Two experiments were conducted to test assembling erectable structures in space: EASE (Experimental Assembly of Structures in Extravehicular Activity), and ACCESS (Assembly Concept for Construction of Erectable Space Structure). In a joint venture between NASA/Langley Research Center in Hampton, Virginia, and the Marshall Space Flight Center (MSFC), EASE and ACCESS were developed and demonstrated at MSFC's Neutral Buoyancy Simulator (NBS). In this STS-61B onboard photo, astronaut Ross, perched on the Manipulator Foot Restraint (MFR) approaches the erected ACCESS. The primary objective of these experiments was to test the structural assembly concepts for suitability as the framework for larger space structures and to identify ways to improve the productivity of space construction.

    Full Text Available Background. Mitral valve replacement can be very difficult to obtain in infants because the valve annulus diameter can be smaller than the available prosthesis. Case Report. We describe the case of a 2-month-old female weighing 3.5 kg affected by mitral valve dysplasia leading to severe valve stenosis. Despite full medication, the clinical conditions were critical and surgery was undertaken. The mitral valve was unsuitable for repair and the orifice of mitral anulus was 12 mm, too small for a mechanical prosthesis. Therefore, a Ross-Kabbani operation was undertaken, replacing the mitral valve with the pulmonary autograft and reconstructing the right ventricular outflow tract with an etherograft. Results. The postoperative course was uneventful and the clinical conditions are good at 4-month follow-up. Conclusion. The Ross-Kabbani operation can be an interesting alternative to mitral valve replacement in infants when valve repair is not achievable and there is little space for an intra-annular mechanical prosthesis implant.

    Diatom taxa present in the inland streams and lakes of the McMurdo Dry Valleys and James Ross Island, Antarctica, are presented in this paper. A total of nine taxa are illustrated, with descriptions of four new species (Luticola austroatlantica sp. nov., Luticola dolia sp. nov., Luticola laeta sp. nov., Muelleria supra sp. nov.). In the perennially ice-covered lakes of the McMurdo Dry Valleys, diatoms are confined to benthic mats within the photic zone. In streams, diatoms are attached to benthic surfaces and within the microbial mat matrix. One species, L. austroatlantica, is found on James Ross Island, of the southern Atlantic archipelago, and the McMurdo Dry Valleys. The McMurdo Dry Valley populations are at the lower range of the size spectrum for the species. Streams flow for 6-10 weeks during the austral summer, when temperatures and solar radiation allow glacial ice to melt. The diatom flora of the region is characterized by species assemblages favored under harsh conditions, with naviculoid taxa as the dominant group and several major diatom groups conspicuously absent. ?? 2008 NRC.

    The Ross Sea, a highly productive region of the Southern Ocean, is expected to experience warming during the next century along with reduced summer sea ice concentrations and shallower mixed layers. This study investigates how these climatic changes may alter phytoplankton assemblage composition, primary productivity, and export. Glider measurements are used to force a one-dimensional biogeochemical model, which includes diatoms and both solitary and colonial forms of Phaeocystis antarctica. Model performance is evaluated with glider observations, and experiments are conducted using projections of physical drivers for mid-21st and late-21st century. These scenarios reveal a 5% increase in primary productivity by midcentury and 14% by late-century and a proportional increase in carbon export, which remains approximately 18% of primary production. In addition, scenario results indicate diatom biomass increases while P. antarctica biomass decreases in the first half of the 21st century. In the second half of the century, diatom biomass remains relatively constant and P. antarctica biomass increases. Additional scenarios examining the independent contributions of expected future changes (temperature, mixed layer depth, irradiance, and surface iron inputs from melting ice) demonstrate that earlier availability of low light due to reduction of sea ice early in the growing season is the primary driver of productivity increases over the next century; shallower mixed layer depths additionally contribute to changes of assemblage composition and export. This study further demonstrates how glider data can be effectively used to facilitate model development and simulation, and inform interpretation of biogeochemical observations in the context of climate change.Plain Language SummaryUnderstanding how the global ocean responds to climate change requires knowing the natural behavior of individual regions and anticipating how future changes will affect each region differently.

    The study aims to test the reliability and validity of the Estonian version of the Swedish universities Scales of Personality (SSP), and to characterize the position of the SSP-measured traits within the basic personality dimensions of the five-factor model. A total of 529 participants completed the Estonian version of the SSP. A subsample of 197 persons completed the SSP together with the Revised NEO Personality Inventory (NEO-PI-R). The internal consistency of the SSP scales was satisfactory. Principal component analysis yielded three factors representing neuroticism, aggression and disinhibition. The factor solution obtained in the Estonian sample was similar to the original SSP study in the Swedish normative sample. NEO-PI-R Neuroticism had highest correlations with SSP neuroticism factor scales. Extraversion had strongest relationship with adventure seeking and low detachment. Agreeableness correlated positively with SSP social desirability and negatively to aggression-irritability scales. Conscientiousness facet Deliberation correlated with Impulsiveness. The Estonian SSP showed acceptable reliability and validity, which confirms that SSP is applicable in different social and cultural background. The SSP measures traits that correspond to the major personality models. The SSP characterizes three broad dimensions of personality, namely neuroticism, disinhibition and aggression, which are useful in assessment of personality correlates of mental disorders.

    For responsible fisheries management of threatened species, it is essential to know the composition of catches and the extent to which fisheries exploit weak wild populations. The threatened Estonian, Finnish and Russian sea trout populations in the Gulf of Finland are targets of mixed-stock fisheries. The fish may originate from rivers with varying production capacities, from different countries, and they may also have either a wild or hatchery origin. In order to resolve the composition of Finnish coastal sea trout catches, we created a standardized baseline dataset of 15 DNA microsatellite loci for 59 sea trout populations around the Gulf of Finland and tested its resolution for mixed-stock analysis of 1372 captured fish. The baseline dataset provided sufficient resolution for reliable mixture analysis at regional group level, and also for most of the individual rivers stocks. The majority (76-80%) of the total catch originated from Finnish sea trout populations, 6-9% came from Russian and 12-15% from Estonian populations. Nearly all Finnish trout in the catch were of hatchery origin, while the Russian and Estonian trout were mostly of wild origin. The proportion of fish in the Finnish catches that originated from rivers with natural production was at least one fifth (22%, 19-23%). Two different spotting patterns were observed among the captured trout, with a small and sparsely spotted form being markedly more common among individuals of Russian (28%) and Estonian origin (22%) than among fish assigned to a Finnish origin (0.7%).

  17. The Baltic Klint beneath the central Baltic Sea and its comparison with the North Estonian Klint

    2016-06-01

    Along its contact with the Baltic Shield, the margin of the East European Platform reveals a well-developed, flooded terraced relief. The most striking and consistent set of escarpments at the contact of the Lower Palaeozoic calcareous and terrigenous rocks, known as the Baltic Klint (BK), extends from northwest of Russia to the Swedish island of Öland. Marine seismic reflection profiling in 1990-2004 revealed the central Baltic Sea Klint (BSK) section in detail and enabled comparison of its geology/geomorphology with a classical klint-section onshore, namely the North Estonian Klint (NEK). The conception of the BK onshore, which is based on the land-sea separating terraced relief in northern Estonia, is not fully applicable beneath the sea. Therefore, we consider that the BSK includes the entire terraced Cambrian outcrop. We suggest the term "Baltic Klint Complex" to include the well-terraced margin of the Ordovician limestone outcrop, which is weakly developed in Estonia. Because of a steady lithological framework of the bedrock layers across the southern slope of the Fennoscandian Shield, the central BSK in the western and the NEK in the eastern part of the Baltic Homocline have largely identical morphologies. The North Estonian Ordovician limestone plateau with the calcareous crest of the BK extends across the central Baltic Sea, whereas morphological changes/variations along the Klint base occur due to the east-westerly lithostratigraphic/thickness changes in the siliciclastic Cambrian sequence. The verge of the NEK, located some 30-50 m above sea level, starts to drop in altitude as its east-westerly course turns to northeast-southwest in western Estonia. Further westwards, the BK shifts gradually into southerly deepening (0.1-0.2°) layers as its crest drops to c. 150 m below sea level (b.s.l.) near Gotska Sandön. This course change is accompanied by a considerable decrease in thickness of the platform sedimentary cover, as below the central Baltic Sea the

    Full Text Available Estonian knowledge of history emanates from the fact that constituting an independent nation has for the most part been nothing but a utopia, and was a reality for a relatively short time. When it comes to selfidentification though, the expression ’a singing people’ is often used by the Estonians to describe themselves. Nostalgia for freedom is reflected in the Estonian culture of almost all periods and is carried on by the singing tradition, where patriotic songs emerge independent of different musical tastes within a particular generation and form an important part of a common Estonian repertoire. Patriotic songs occupy a central place in several fields of Estonian culture: besides music culture also in popular culture,and literary history – the works of poetry which have gained the most popularity are those which when put to music have been the most widely spread among the people. The main part of the most popular Estonian patriotic songs are choral songs from the national awakening at the end of the 19th century. Despite the national programmes aiming to wipe out ‘bourgeois nationalism’, they were sung at the song festivals in the Soviet era and were published in song books, expressing the people’s nostalgia for freedom lost. After the end of the Second World War, there was an attempt at launching a kind of patriotic new creation, where patriotism was merged with Soviet pathos; the aim was to show that the people’s utopia was in fact communism, but not a single one of those songs made it into the people’s common repertoire. Only the patriotic songs composed in the 1980s during the so-called new national awakening reached a popularity comparable to that of the old songs. The discourse on ’Estonianness’ and the shaping of a matching repertoire under imperial Russian rule took place under very different circumstances than its preservation and development in the second half of the 20th century under Soviet occupation, but

    In temperate forests, some green plants, namely pyroloids (Pyroleae, Ericaceae) and some orchids, independently evolved a mode of nutrition mixing photosynthates and carbon gained from their mycorrhizal fungi (mixotrophy). Fungal carbon is more enriched in 13C than photosynthates, allowing estimation of the proportion of carbon acquired heterotrophically from fungi in plant biomass. Based on 13C enrichment, mixotrophic orchids have previously been shown to increase shoot autotrophy level over the growth season and with environmental light availability. But little is known about the plasticity of use of photosynthetic versus fungal carbon in pyroloids. Plasticity of mixotrophy with leaf age or light level (estimated from canopy openness) was investigated in pyroloids from three Estonian boreal forests. Bulk leaf 13C enrichment of five pyroloid species was compared with that of control autotrophic plants along temporal series (over one growth season) and environmental light gradients (n=405 samples). Mixotrophic 13C enrichment was detected at studied sites for Pyrola chlorantha and Orthilia secunda (except at one site for the latter), but not for Chimaphila umbellata, Pyrola rotundifolia and Moneses uniflora. Enrichment with 13C did not vary over the growth season or between leaves from current and previous years. Finally, although one co-occurring mixotrophic orchid showed 13C depletion with increasing light availability, as expected for mixotrophs, all pyroloids responded identically to autotrophic control plants along light gradients. A phylogenetic trend previously observed is further supported: mixotrophy is rarely supported by 13C enrichment in the Chimaphila + Moneses clade, whereas it is frequent in the Pyrola + Orthilia clade. Moreover, pyroloid mixotrophy does not respond plastically to ageing or to light level. This contrasts with the usual view of a convergent evolution with orchids, and casts doubt on the way pyroloids use the carbon gained from their

    To examine non-cancer morbidity in the Estonian Chernobyl cleanup workers cohort compared with the population sample with special attention to radiation-related diseases and mental health disorders. Register-based cohort study. Estonia. An exposed cohort of 3680 men (cleanup workers) and an unexposed cohort of 7631 men (population sample) were followed from 2004 to 2012 through the Population Registry and Health Insurance Fund database. Morbidity in the exposed cohort compared with the unexposed controls was estimated in terms of rate ratio (RR) with 95% CIs using Poisson regression models. Elevated morbidity in the exposed cohort was found for diseases of the nervous system, digestive system, musculoskeletal system, ischaemic heart disease and for external causes. The most salient excess risk was observed for thyroid diseases (RR=1.69; 95% CI 1.38 to 2.07), intentional self-harm (RR=1.47; 95% CI 1.04 to 2.09) and selected alcohol-related diagnoses (RR=1.25; 95% CI 1.12 to 1.39). No increase in morbidity for stress reactions, depression, headaches or sleep disorders was detected. No obvious excess morbidity consistent with biological effects of radiation was seen in the exposed cohort, with the possible exception of benign thyroid diseases. Increased alcohol-induced morbidity may reflect alcohol abuse, and could underlie some of the higher morbidity rates. Mental disorders in the exposed cohort were probably under-reported. The future challenge will be to study mental and physical comorbidities in the Chernobyl cleanup workers cohort. Published by the BMJ Publishing Group Limited.

    We investigated Estonian population and its selected subgroups for serological evidence of exposure to Ascaris lumbricoides, Echinococcus spp., Taenia solium, Toxocara canis, Toxoplasma gondii, and Trichinella spiralis. Serum samples from 999 adults representing general population, 248 children aged 14–18, 158 veterinarians, 375 animal caretakers, and 144 hunters were tested for specific immunoglobulin G antibodies against the selected parasites using commercial enzyme immunoassays (ELISA). Sera yielding positive or twice grey zone Echinococcus spp, T. solium, T. canis, and T. spiralis results were subjected to western blot (WB) analysis. In the general population, based on the ELISA results, the A. lumbricoides seroprevalence was 12.7%, Echinococcus spp. seroprevalence was 3.3%, T. solium seroprevalence was 0.7%, T. canis seroprevalence was 12.1%, T. gondii seroprevalence was 55.8%, and T. spiralis seroprevalence was 3.1%. Ascaris lumbricoides seroprevalences were higher in children and in animal caretakers than in the general population, and T. canis seroprevalence was higher in animal caretakers than in the general population. Compared with the general population, Echinococcus spp. seroprevalence was higher in children. By contrast, T. gondii seroprevalence was higher in animal caretakers, and lower in children, than in the general population. In the general population, the WB-confirmed Echinococcus spp. seroprevalence was 0.5%, T. solium cysticercosis seroprevalence was 0.0%, Toxocara spp. seroprevalence was 14.5%, and Trichinella spp. seroprevalence was 2.7%. WB-confirmed Toxocara spp. seroprevalence was higher in animal caretakers than in the general population. We found serological evidence of exposure to zoonotic parasites in all tested groups. This calls for higher awareness of zoonotic parasitic infections in Estonia. PMID:27723790

    In this study, a stochastic predictive model stimulating a constant infection pressure of Eimeria was used to estimate production outcome, economic, and effects of treatment decisions in a dairy herd of 100 cows. The intestinal parasite cause problems mainly in calves, and is known to have long term effects on the growth rate, and in severe cases can result in mortalities. Due to the inconspicuous nature of the parasite, the clinical signs and sub-clinical manifestations it may produce can be overlooked. Acquired data from literature and Estonian dairy farms were implemented in the SimHerd IV model to simulate three scenarios of symptomatic treatment: no calves treated (NT), default estimate of the current treatment strategy (DT), and all calves treated (AT). Effects of metaphylactic treatment were studied as a lowering of the infection pressure. Delay in the age for beginning of insemination of heifers was the effect with the largest economic impact on the gross margin, followed by calf mortality and reduction in growth rate. Large expenses were associated with the introduction of replacement heifers and feeding of heifers as a result of the delay in reaching a specific body weight at calving. Compared to the control scenarios, with no effects and treatments of Eimeria, dairy farmers were estimated to incur annual losses ranging 8-9% in the balanced income. Providing metaphylactic drugs resulted in an increased gross margin of 6-7%. Purchase of new heifers compensated for some production losses that would otherwise have enhanced expenses related to Eimeria. The simulation illustrates how effects of Eimeria infections can have long lasting impact on interacting management factors. It was concluded that all three simulated symptomatic treatment regimes provided only small economic benefits if they were applied alone and not in combination with lowering of infection pressure.

    The application of high-throughput sequencing methods has raised doubt in the concept of the uniform healthy vaginal microbiota consisting predominantly of lactobacilli by revealing the existence of more variable bacterial community composition. As this needs to be analyzed more extensively and there is little straightforward data regarding the vaginal mycobiome of asymptomatic women we aimed to define bacterial and fungal communities in vaginal samples from 494 asymptomatic, reproductive-age Estonian women. The composition of the vaginal microbiota was determined by amplifying bacterial 16S rRNA and fungal internal transcribed spacer-1 (ITS-1) regions and subsequently sequencing them using 454 Life Sciences pyrosequencing. We delineated five major bacterial community groups with distinctive diversity and species composition. Lactobacilli were among the most abundant bacteria in all groups, but also members of genus Gardnerella had high relative abundance in some of the groups. Microbial diversity increased with higher vaginal pH values, and was also higher when a malodorous discharge was present, indicating that some of the women who consider themselves healthy may potentially have asymptomatic bacterial vaginosis (BV). Our study is the first of its kind to analyze the mycobiome that colonizes the healthy vaginal environment using barcoded pyrosequencing technology. We observed 196 fungal operational taxonomic units (OTUs), including 16 OTUs of Candida spp., which is more diverse than previously recognized. However, assessing true fungal diversity was complicated because of the problems regarding the possible air-borne contamination and bioinformatics used for identification of fungal taxons as significant proportion of fungal sequences were assigned to unspecified OTUs.

    Occupational exposures make important contributions to asthma morbidity. The role of low/moderate level irritant exposures remains unclear. We aimed to determine which occupational exposures are associated with asthma in an eastern European country with low asthma prevalence. The Estonian Genome Center of University of Tartu collected data from 50 077 adults in 2002-2011. Asthma was assessed through a questionnaire regarding diagnosed diseases, current health status and medication. Exposures to 22 agents during the current and longest held jobs were estimated using an asthma-specific job-exposure matrix. Analyses included 34 015 subjects (aged 18-65 years, 67.0% females), of which 1209 (3.6%) reported asthma (608 with physician-confirmed diagnosis). After adjusting for age, sex and smoking habits, lifetime occupational exposure to known asthmagens (20.4%) was significantly associated with physician-diagnosed asthma (OR 1.28, 95% CI 1.03-1.59), especially high molecular weight agents (flour: OR 2.36, 95% CI 1.31-4.27; animals: OR 1.62, 95% CI 1.00-2.60). Exposure to low/moderate levels of irritants (17.4%) was associated with physician-diagnosed asthma (OR 1.88, 95% CI 1.48-2.37). More pronounced associations were observed in subjects reporting current treated asthma. Beyond confirming the effect of known asthmagens (which are well-known, mostly from observations in western countries), the results provide evidence for a role of low/moderate exposure to irritants. This finding, observed in a country with a low prevalence of asthma and atopy, provides new insight into the understanding of asthma heterogeneity.

    Full Text Available Any consideration of Estonian theatre from the point of view of biographical theatre needs to include the work of playwright and director Merle Karusoo. Productions based on various life narratives (diaries, letters, biographical interviews form the core of her work that can be defined as biographical or memory theatre. Her work has also been viewed within the context of community theatre or political theatre; Karusoo has herself referred to her work as sociological theatre. Life narratives have functioned in Karusoo’s productions as the basis for restoring oppressed or denied collective discourses of memory. Her productions emerged within the framework of the more general process of restoration of historical heritage and the rehabilitation of collective memory at the end of the 1980s and the beginning of the 1990s. Life story can be viewed as the essence of Merle Karusoo’s theatre. The personal in the life story in the production activates the emotional memory of the audience; for older generations such theatre facilitates a legitimisation of remembering one’s life story in entirety, and for younger generations it functions as a vehicle of collective, historical and national memory. The current article outlines the main stages of Karusoo’s biographical theatre, highlights major productions of each stage and provides an overview of their reception.

    The Self-Consciousness Scale (SCS), developed by Fenigstein, Scheier, and Buss (1975), was adapted to the Estonian language. In general, the results supported the 3-factor structure of the SCS. However, many items in the subscales did not load as expected. A 26-item modified scale, the Estonian SCS (ESCS), is presented. A joint factor analysis of the ESCS and the NEO Personality Inventory (NEO-PI) scales led to a 5-factor solution, where all the factors that emerged were identified as the Big Five personality dimensions, the ESCS subscales loading most significantly on 3 of these factors: Neuroticism (N), Extraversion (E), and Openness to Experience (O). Correlation analysis revealed a pattern of correlations, characterized by the strongest associations between Social Anxiety and E (r = -.77), Public Self-Consciousness (PubSC) and N (r = .40), and Private Self-Consciousness (PrivSC) and O (r = .34), which quite well corresponds to the pattern of correlations that was reported for the original versions of the SCS and the NEO-PI (Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993). We can conclude that all the SCS subscales can be sufficiently well interpreted in terms of the Big Five model of personality dimensions--PrivSC and PubSC appear to describe some variations of the Big Five themes that are not fully elaborated by the NEO-PI rather than being completely independent domains of individual differences.

    Full Text Available Estonia is famous among politicians for its e-Governance policies. One core ingredient for this progress is the abolishment of outdated technologies and standards as this kind of legacy policy slows down the innovation process. This short paper adapts the Estonian approach towards legacy policy and proposes a political symbol initiated by the EU Presidency Trio of the United Kingdom, Bulgaria and Estonia. The entire topic was inspired by the motivation of the Estonian government to use the presidency to make a mark for Estonia. The twice-yearly occurring process of introducing and disabling the summertime, is not only annoying but has also almost exclusively negative impacts. Meanwhile, the summertime itself comes with many aspects of questionable impact and even opposing empirical results, but it also has some generally agreed upon positive influences. This paper takes side against the process of changing times, but does not take position for one of the possible solutions. This short article shall only inform and show the possibilities in regard to the summer time, the EU presidency and the political symbolism of celebrating the centenary of the First World War.

  10. Two Decades of Estonian Police and the (Irrelevance of Police Models for the Development of Safety Policy

    2016-07-01

    Full Text Available Police models are designed to improve safety in society. Although Estonia has not deliberately used any (combination of police models for developing its policies of safety and its police reforms since the country regained independence, its safety has improved considerably during the last couple of decades. The scholarly discussions about police models are overwhelmingly about the possible effects of different models on safety management and about their application to particular countries. However, countries like Estonia with no consistent conceptions of police have received little attention in academic literature. We aim to fill this gap by analysing the developments of the Estonian police in its philosophical, strategic, tactical and organisational dimensions over the period between 1991 and 2013. The analysed materials include the official police development plans, legislation, statutes, training programs and statistics about the police. Our analysis shows that although safety in Estonia has improved considerably, developments of the Estonian police are characterised by internal discrepancies and inconsistencies. In view of this, we put forth some hypotheses for further studies regarding policy development in a situation where policy is not explicitly stated or where organisational reforms are seen not as “simple” or “complex” problems, but as “wicked” problems.

    Rutt Hinrikus

    2012-04-01

    Full Text Available In this article I examine the development of Estonian autobiographical writing from its first manifestations to published memoirs, and the development of life writing and its diversification. The beginnings of life writing can be traced back to Estonian folk song and Estonian incidental poetry. The Moravian Brethren movement in Estonia in the 18th century promoted the spread of canonical autobiography. The Moravian Brethren offered alternative opportunities for self-realisation for Estonians who were serfs, and were therefore popular with the people. The practice of the Moravian Brethren made use of retelling and writing about the life of the congregation members, which sometimes became suitable biographies in print, especially stories of awakening. Several manuscript biographies have survived from the Brethren times, such as the biographies of Mäletu Jaan and Mihkel Sarapuu. In addition to the history of the Moravian Brethren movement, these biographies give information about the educational situation and living conditions of the people of the time. The Estonian life writing tradition emerged within the reigning Baltic German cultural space thanks to the Estophiles among the Baltic Germans (J. H. Rosenplänter and the first Estonian men of letters; from the early 19th century we have the diary by Rosenplänter, an estophile pastor from Pärnu, and the diary by the Estonian poet, the then-student Kristjan Jaak Peterson, both in the Estonian language. Johann Voldemar Jannsen, the founder of Estonian-language journalism, kept a diary in the German language for a longer period of time; it was usual that the first Estonian intellectuals (Lilli Suburg, and others in the late 19th century wrote in German. Admittedly, the first Estonian-language life history was written by a forward-looking 19th century peasant named Märt Mitt (1833-1912, who was conscious of himself as a historical subject and gave his memoirs, begun in the 1880s, a memorable title

    2016-03-01

    We present the second of a two-part seismic analysis of the bright, hot ZZ Ceti stars GD 165 and Ross 548. In this second part, we report the results of detailed searches in parameter space for identifying an optimal model for each star that can account well for the observed periods, while being consistent with the spectroscopic constraints derived in our first paper. We find optimal models for each target that reproduce the six observed periods well within ∼0.3% on the average. We also find that there is a sensitivity on the core composition for Ross 548, while there is practically none for GD 165. Our optimal model of Ross 548, with its thin envelope, indeed shows weight functions for some confined modes that extend relatively deep into the interior, thus explaining the sensitivity of the period spectrum on the core composition in that star. In contrast, our optimal seismic model of its spectroscopic sibling, GD 165 with its thick envelope, does not trap/confine modes very efficiently, and we find weight functions for all six observed modes that do not extend into the deep core, hence accounting for the lack of sensitivity in that case. Furthermore, we exploit after the fact the observed multiplet structure that we ascribe to rotation. We are able to map the rotation profile in GD 165 (Ross 548) over the outermost ∼20% (∼5%) of its radius, and we find that the profile is consistent with solid-body rotation.

  1. Mg/Casea surface temperatures during the Marine Isotope Stage 31 collapse of the Ross Ice Shelf

    Dunbar, G. B.

    2012-04-01

    The recovery of the AND-1b and CRP-1 drill cores from the Southwest Ross Sea highlighted the potential instability in of the Ross Ice Shelf and the West Antarctic Ice Sheet it buttresses. Both cores recovered a few individuals of the planktonic foraminifera Neogloboquadrina pachyderma from marine isotope stage (MIS) 31. This interval is significant because it marks the youngest occurrence of open ocean diatom sediment at AND-1b, which is now situated under the McMurdo Ice Shelf, indicating a substantial retreat of the Ross Ice Shelf occurred during this interglacial. However, sediment deposited after MIS 31 at both sites is represented only by glacial-dominated sediment, suggesting a critical environmental threshold had been crossed enabling the Ross Ice Shelf to form and persist. Numerical modeling by Pollard and DeConto (Nature, 2009) suggested that sub-ice oceanic melting is a critical element in the stability of ice shelves and that "WAIS will begin to collapse when nearby ocean temperatures warm by roughly 5°C." Laser ablation ICPMS measurement of the Mg/Ca content of N. pachyderma shows that although there is considerable heterogeneity in the distribution of Mg in their tests the mean Mg/Ca of a sample population appears proportional to calcification temperature. By empirically calibrating Mg/Ca in CRP-1 N. pachyderma against values measured in modern populations collected from Ross Sea and Southern Ocean sites with SSTs ranging from 1.2°C to 14°C it is concluded that SST during MIS 31 was warmer than today by 5-9°C, consistent with model projections.

Ross procedure was performed in 100 patients at our institution between 1993 and 2011. In 76 patients, complete follow-up data were available. Their median age at surgery was 16 (0.4-58) years (76 % males; 95 % with congenital aortic valve disease). Median follow-up duration was 5.2 years (0.3-16.0 years). We analyzed their clinical and echocardiographic follow-up to identify possible risk factors for neo-aortic root dilatation and dysfunction. Ross procedure included reduction plasty of the native ascending aorta in 25 % of patients. During follow-up, 21 patients (28 %) developed neo-aortic root dilatation, 38 patients (50 %) dilatation oft the native ascending aorta and 7 patients (9 %) at least moderate neo-aortic regurgitation. Univariate risk factors for neo-aortic root dilatation were preoperative aortic regurgitation (p = 0.04), concomitant reduction plasty of the ascending aorta (p = 0.009) and a longer duration of follow-up (p = 0.005). Younger age at surgery was associated with dilatation of the ascending aorta (p = 0.03). Reoperation on the neo-aortic root because of severe dilatation was necessary in 6 patients (8 %), where 2 patients had at least moderate neo-aortic root regurgitation. Neo-aortic root and aortic dilatation are common after the Ross procedure. This is often combined with neo-aortic valve dysfunction. Close follow-up of these patients is mandatory.

    An integrated study of onshore and offshore geology of the Ross Sea region (namely, Victoria Land, north of Ross Island, and the Ross Sea, Antarctica) has revealed a complex, post-Eocene tectonic framework. Regional NW-SE right-lateral, strike-slip faults are the outstanding feature of this framework and overprint an older Mesozoic extensional event, responsible for formation of N-S basins in the Ross Sea. The Cenozoic framework includes kinematic deformation and reactivation along the NW-SE faults, including formation of pull-apart basins, both positive and negative flower structures, and push-up ridges. N-S extensional faults are well developed between NW-SE faults and indicate E-W extension during the Cenozoic, produced by the NW-SE right-lateral strike-slip motion together with regional crustal extension. NNW-SSE compression, induced by the right-lateral, strike-slip kinematics, is indicated by locally inverted NE-SW faults and basins. The evolution, geometry, and location of the Rennick Graben and the Lanterman Range fit well into this model. Variations in the deformational style across the region can be linked to corresponding variations in the bulk crustal rheology, from brittle behavior in the west, to ductile deformation (at subseismic-scale resolution) near the Eastern Basin. A semibrittle region that favors N-S clustering of Cenozoic magmatic activity lies in between. In this region, Cenozoic volcanoes develop at the intersections of the NW-SE and the major N-S faults. The NW-SE faults cut almost continually from the Ross Sea to East Antarctica through lithospheric sectors with different rheology and thickness. At least two of the NW-SE faults correspond to older Paleozoic terrane boundaries in northern Victoria Land. The NW-SE faults link in the Southern Ocean with major transform faults related to the plate motions of Australia, New Zealand, and Antarctica.

  4. Iron limitation of a springtime bacterial and phytoplankton community in the Ross Sea: implications for vitamin B12 nutrition

    Full Text Available The Ross Sea is home to some of the largest phytoplankton blooms in the Southern Ocean. Primary production in this system has previously been shown to be iron limited in the summer and periodically iron and vitamin B12 colimited. In this study, we examined trace metal limitation of biological activity in the Ross Sea in the austral spring and considered possible implications for vitamin B12 nutrition. Bottle incubation experiments demonstrated that iron limited phytoplankton growth in the austral spring while B12, cobalt, and zinc did not. This is the first demonstration of iron limitation in a Phaeocystis antarctica-dominated, early season Ross Sea phytoplankton community. The lack of B12 limitation in this location is consistent with previous Ross Sea studies in the austral summer, wherein vitamin additions did not stimulate P. antarctica growth and B12 was limiting only when bacterial abundance was low. Bottle incubation experiments and a bacterial regrowth experiment also revealed that iron addition directly enhanced bacterial growth. B12 uptake measurements in natural water samples and in an iron fertilized bottle incubation demonstrated that bacteria serve not only as a source for vitamin B12, but also as a significant sink, and that iron additions enhanced B12 uptake rates in phytoplankton but not bacteria. Additionally, vitamin uptake rates did not become saturated upon the addition of up to 95 pM B12. A rapid B12 uptake rate was observed after 13 min, which then decreased to a slower constant uptake rate over the next 52 hours. Results from this study highlight the importance of iron availability in limiting early season Ross Sea phytoplankton growth and suggest that rates of vitamin B12 production and consumption may be impacted by iron availability.

    Full Text Available This paper explores the use of the Panzar-Rosse statistic as a basis for empirical assessment of competitive conditions among Tunisian deposit banks. The elaborated model has been tested with an interest revenues equation and a total revenues equation. Proceeding by means of an Ordinary Least Square analysis, the H-statistics is respectively estimated at 0.87 and 0.91. The computations undertaken using bank fixed effects and bank random effects General Least Square methods yield similar results. With reference to the reviewed literature, we are inclined to believe that Tunisian banks implement neither a joint monopoly nor a collusive competition context, and that they evolve within an oligopolistic competition context in a contestable market. Thus, it confirms the presence of a competitive environment.

    Ross River virus (RRV) infection is a debilitating disease that has a significant impact on population health, economic productivity, and tourism in Australia. This study examined epidemiologic patterns of RRV disease in Queensland, Australia, during January 2001–December 2011 at a statistical local area level. Spatio-temporal analyses were used to identify the patterns of the disease distribution over time stratified by age, sex, and space. The results show that the mean annual incidence was 54 per 100,000 persons, with a male:female ratio of 1:1.1. Two space-time clusters were identified: the areas adjacent to Townsville, on the eastern coast of Queensland, and the southeast areas. Thus, although public health intervention should be considered across all areas in which RRV occurs, it should specifically focus on high-risk regions, particularly during summer and autumn to reduce the social and economic impacts of RRV infection.

    Although changes in sea-ice cover contribute to global climatic variations, they are poorly constrained for periods earlier than the last decades. More records are especially required around Antarctica, where the formation of Antarctic Bottom Waters participates to global thermohaline circulation. However, this region provided only a few marine sediment cores spanning the entire Holocene, especially because of generally low sedimentation rates. This study focuses on marine sediment core ANTA99-CJ5 (73°49'S; 175°39'E), located in the open sea ice zone (OSIZ) of the western Ross Sea. We analyzed several lipid biomarkers: highly branched isoprenoids (HBIs), sterols, diols and GDGTs. The combination of several biomarkers and the comparison of these results with a diatom record previously published on the same core enabled us to trace past changes in temperatures as well as in sea-ice condition over the last 11,600 years.

    In Australia, Ross River virus (RRV) is predominantly identified and managed through passive health surveillance. Here, the proactive use of environmental datasets to improve community-scale public health interventions in southeastern Tasmania is explored. Known environmental drivers (temperature, rainfall, tide) of the RRV vector Aedes camptorhynchus are analysed against cumulative case records for five adjacent local government areas (LGAs) from 1993 to 2009. Allowing for a 0- to 3-month lag period, temperature was the most significant driver of RRV cases at 1-month lag, contributing to a 23·2% increase in cases above the long-term case average. The potential for RRV to become an emerging public health issue in Tasmania due to projected climate changes is discussed. Moreover, practical outputs from this research are proposed including the development of an early warning system for local councils to implement preventative measures, such as public outreach and mosquito spray programmes.

    Antarctica's ice shelves are thinning at an increasing rate, affecting their buttressing ability. Channels in the ice shelf base unevenly distribute melting, and their evolution provides insight into changing subglacial and oceanic conditions. Here we used phase-sensitive radar measurements to estimate basal melt rates in a channel beneath the currently stable Ross Ice Shelf. Melt rates of 22.2 ± 0.2 m a-1 (>2500% the overall background rate) were observed 1.7 km seaward of Mercer/Whillans Ice Stream grounding line, close to where subglacial water discharge is expected. Laser altimetry shows a corresponding, steadily deepening surface channel. Two relict channels to the north suggest recent subglacial drainage reorganization beneath Whillans Ice Stream approximately coincident with the shutdown of Kamb Ice Stream. This rapid channel formation implies that shifts in subglacial hydrology may impact ice shelf stability.

  10. Influence of submarine morphology on bottom water flow across the western Ross Sea continental margin

    Multibeam sonar bathymetry documents a lack of significant channels crossing outer continental shelf and slope of the western Ross Sea. This indicates that movement of bottom water across the shelf break into the deep ocean in this area is mainly by laminar or sheet flow. Subtle, ~20 m deep and up to 1000 m wide channels extend down the continental slope, into tributary drainage patterns on the upper rise, and then major erosional submarine canyons. These down-slope channels may have been formed by episodic pulses of rapid down slope water flow, some recorded on bottom current meters, or by sub-ice melt water erosion from an icesheet grounded at the margin. Narrow, mostly linear furrows on the continental shelf thought to be caused by iceberg scouring are randomly oriented, have widths generally less than 400 m and depths less than 30m, and extend to water depths in excess of 600 m.

    The fractionation of atmospheric sea-salt has been investigated by glaciochemical analysis of the sea-salt deposited on the snow covering the small ice cap of James Ross Island, Antarctic Peninsula, at an elevation of 1640m. The data show that, generally, but not always, the sea-salt deposited at this location most likely originates directly from seawater, as is the case at lower latitudes. It is found that the original chemical composition of the sea-salt aerosol is significantly modified, in particular by the reaction of sea-salt particles in the atmosphere with acid species. A ternary diagram (sodium, chloride, sulfate) is used to enlighten the involved modification processes. The study points out the frequent formation of HCl in the regional atmosphere. (Author)

    Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on the human spirit. It is also shown, through the analysis of David Mamet’s glengarry Glen Ross, that despite the promise of the dream it contains many contradictions. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, for instance, as  the most prominent of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life.

Goals of this student-run project include: 1) To monitor the rocky intertidal habitat and develop a baseline database of invertebrates and algal density and abundance; 2) To contribute to the conservation of the rocky intertidal habitat through education of students and visitors about intertidal species; 3) To increase stewardship in the Gulf of the Farallones National Marine Sanctuary; and 4) To contribute abundance and population data on key algae and invertebrate species to the national database, LiMPETS (Long Term Monitoring Program & Experiential Training for Students). Each fall student volunteers complete an intensive training course on the natural history of intertidal invertebrates and algae, identification of key species, rocky intertidal monitoring techniques, and history of the sanctuary. Students identify and count key invertebrate and algae species along two permanent transects and, using randomly determined points, within two permanent 200 m2 areas, in fall, winter, and late spring. Using data from the previous years, we will compare population densities, seasonal abundance and long-term population trends of key algal and invertebrate species, including Tegula funebralis, Anthopluera elegantissima, Cladophora sp. and Fucus sp.. Future analyses and investigations will include intertidal abiotic factors (including water temperature, pH and human foot-traffic) to enhance insights into the Duxbury Reef ecosystem, in particular, the high

    For a 3-month period between May and July of 2005, we examine the response of the Advanced Microwave Scanning Radiometer (AMSR-E) Enhanced NASA Team 2 (NT2) and AMSR-E Bootstrap (ABA) ice concentration algorithms to large areas of thin ice of the Ross Sea polynyas. Coincident Envisat Synthetic Aperture Radar (SAR) coverage of the region during this period offers a detailed look at the development of the polynyas within several hundred kilometers of the ice front. The high-resolution imagery and derived ice motion fields show bands of polynya ice, covering up to approximately 105 km(sup 2) of the Ross Sea, that are associated with wind-forced advection. In this study, ice thickness from AMSR-E 36 GHz polarization information serves as the basis for examination of the response. The quality of the thickness of newly formed sea ice (<10 cm) from AMSR-E is first assessed with thickness estimates derived from ice surface temperatures from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. The effect of large areas of thin ice in lowering the ice concentration estimates from both NT2/ABA approaches is clearly demonstrated. Results show relatively robust relationships between retrieved ice concentrations and thin ice thickness estimates that differ between the two algorithms. These relationships define the approximate spatial coincidence of ice concentration and thickness isopleths. Using the 83% (ABA) and 91% (NT2) isopleths as polynya boundaries, we show that the computed coverage compares well with that using the estimated 10-cm thickness contour. The thin ice response characterized here suggests that in regions with polynyas, the retrieval results could be used to provide useful geophysical information, namely thickness and coverage.

    The intrusion of Circumpolar Deep Water (CDW) is the primary source of heat, salt and nutrients onto Antarctica's continental shelves and plays a major role in the shelf physical and biological processes. Different studies have analyzed the processes responsible for the transport of CDW across the Ross Sea shelf break, but until now, there are no continuous observations that investigate the timing of the intrusions. Also, few works have focused on the effect of the tides that control these intrusions. In the Ross Sea, the CDW intrudes onto the shelf in several locations, but mostly along the troughs. We use hydrographic observations and a mooring placed on the outer shelf in the middle of the Drygalski Trough in order to characterize the spatial and temporal variability of CDW inflow onto the shelf. Our data span from 2004 to the beginning of 2014. In the Drygalski Trough, the CDW enters as a 150 m thick layer between 250 and 400 m, and moves upward towards the south. At the mooring location, about 50 km from the shelf break, two main CDW cores can be observed: one on the east side of the trough spreading along the west slope of Mawson Bank from about 200 m to the bottom and the other one in the central-west side from 200 m to about 350 m depth. A signature of this lighter and relatively warm water is detected by the instruments on the mooring at bottom of the Drygalski Trough. High frequency periodic CDW intrusion at the bottom of the trough is related to the diurnal and spring/neap tidal cycles. At lower frequency, a seasonal variability of the CDW intrusion is noticed. A strong inflow of CDW is observed every year at the end of December, while the CDW inflow is at its seasonal minimum during the beginning of the austral fall. In addition an interannual variability is also evident. A change of the CDW intrusion before and after 2010 is observed.

    A unique feature of the polar troposphere is the strong impact of halogen photochemistry, in which reactive halogen species (RHS) are responsible for ozone depletion as well as the oxidation of elemental mercury and dimethyl sulphide. The source, however, as well as release and recycling mechanisms of these halogen species are far from being completely understood, especially the role of chlorine and iodine compounds. Reactive chlorine, bromine and iodine compounds are thought to be released from sea salt particles or produced by the photolysis of halocarbons and I2 emitted by the ocean. Here we present observations of halogen oxides, ozone and nitrogen dioxide conducted for three months during austral spring 2012 on Ross Island, Antarctica. Measurements were performed with a suite of remote sensing instruments. An active long-path differential optical absorption spectroscopy (LP-DOAS) system was set up, measuring several species (BrO, O3, NO2, OBrO, IO, OIO, I2, ClO, OClO, CHOCHO, HCHO, HONO) continuously for the whole period, with two light paths over first year sea ice. In addition, a passive MAX-DOAS as well as a new Cavity-Enhanced (CE)-DOAS system were used for mobile halogen oxide measurements on a variety of locations around Ross Island (sea ice, shelf ice, snow, coastal, etc.), with top surface layer pH measurements performed at the different measurement sites. First results show highly variable ozone concentrations including partial Ozone Depletion Events (ODEs), as well as concentrations of BrO up to 16ppt and NO2 up to 15ppb. Suprisingly, a high variation of ozone was observed without significant amounts of BrO, indicating already depleted air masses transported to the measurement site and/or NOx chemistry inhibiting halogen radical reactions.
