Influence of deficit irrigation on nutrient indices in wine grape (Vitis vinifera L.)  [PDF]
Krista Shellie, Brad Brown
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.32031
Abstract: Deficit irrigation is widely used in wine grape production (Vitis vinifera L.) to meet wine quality goals yet its influence on tissue nutrient indices has not been well studied. The objective of this research was to determine whether response to water deficit compromised the prescriptive usefulness of tissue nutrient analyses. Tissue macro and micronutrient composition at bloom and veraison were evaluated over multiple seasons in nine wine grape cultivars grown under well-watered or deficit-irrigated conditions. Deficit-irrigated vines sampled at veraison had 2 to 12-fold higher petiole nitrate-nitrogen concentration, 6% lower blade nitrogen concentration and 13% lower blade copper concentration compared to well-watered vines. Water deficit influenced blade potassium concentration at veraison differently according to cultivar and was lower (cv. Malbec, Petite syrah, Viognier, Lemberger and Sangiovese), higher (cv. Merlot, Cabernet franc and Cabernet Sauvignon) or similar (cv. Grenache) to well-watered vines. Results from this study indicate that nutrient analysis of petiole or blade tissue sampled at veraison has limited diagnostic and prescriptive usefulness when vines are grown under a water deficit.
Health Promotion in Ecuador: A Solution for a Failing System  [PDF]
Dana Rasch, Krista Bywater
Health (Health) , 2014, DOI: 10.4236/health.2014.610115
Abstract: In 2008, the newly written Ecuadorian Constitution guaranteed access to healthcare for all citizens. Consequently, a vast amount of resources have been directed toward rebuilding the public healthcare system, which was in shambles due to the effects of neoliberalism. Although national healthcare studies show positive outcomes, community-based research studies from an impoverished rural barrio in southern Ecuador indicate that the public healthcare system has been unable to address a health epidemic. Based on several years of fieldwork, we argue that the failure originates from the continued functioning of the biomedical model of healthcare as the dominant health discourse in Ecuador. The ensuing result has been the construction of health system governed by an “administrative state” that enforces health policies from the top-down and delivers “episodic” emergency-style care. Accordingly, we maintain that the Ministry of Health (MOH) should create a nationwide community-based health promoter program guided by the principles of health promotion.
Clinical and Radiographic Factors Do Not Accurately Diagnose Smear-Negative Tuberculosis in HIV-infected Inpatients in Uganda: A Cross-Sectional Study

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0009859
Abstract: Although World Health Organization guidelines recommend clinical judgment and chest radiography for diagnosing tuberculosis in HIV-infected adults with unexplained cough and negative sputum smears for acid-fast bacilli, the diagnostic performance of this approach is unknown. Therefore, we sought to assess the accuracy of symptoms, physical signs, and radiographic findings for diagnosing tuberculosis in this population in a low-income country with a high incidence of tuberculosis.
Seltsi muuseumist riigi keskmuuseumiks: ikka ajutiste lahendustega / Changes in the Estonian National Museum from 1909 to the present.

Abstract: 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 years we, the employees of the ENM, have been asking serious questions: Are we ready to develop the national museum in the context of a modern information society? How do we balance between the globalization of cultural developments and the growing need for local communities to secure their roots and heritage? Are we ready to play an important role in the quality of individual lives and in the quality of community? Can we help to construct a sort of collective social memory and fulfill community relations strategies?We know that the ENM’s future should be to operate with an open spirit and balance between the local and the global, the persona
Cover Image Notes on bat diversity at Berenty Private Reserve and Beza Mahafaly Special Reserve in southern Madagascar

Abstract: Surveys of bat diversity are rare for the southern domain of Madagascar. Mistnetting for bats took place at Berenty Private Reserve in southeastern Madagascar during a six months study in 2009 and at Beza Mahafaly Special Reserve in southwestern Madagascar for one month in 2011. At Berenty, Hipposideros commersoni, Triaenops rufus, Myotis goudoti, and Miniopterus spp. were captured along trails and clearings inside forests. Two bats, T. rufus and Miniopterus sp., were captured near the Beza Mahafaly Special Reserve. These captures increase the known bat diversity reported for both sites, but more surveys at Berenty and Beza Mahafaly are recommended. RéSUMéDans le Sud de Madagascar, les études sur les chauves-souris sont rares. Des opérations de capture furent conduites dans la réserve privée de Berenty dans le cadre d’une étude de six mois en 2009 puis dans la Réserve Spéciale de Beza Mahafaly pendant un mois en 2011. Avant cette étude à Berenty, la biodiversité microchiroptère de la réserve était méconnue. Hipposideros commersoni, Triaenops rufus, Myotis goudoti et Miniopterus spp. furent capturés le long des sentiers et dans des clairières à Berenty. La capture de T. rufus et de Miniopterus sp. près de Beza Mahafaly porta à sept le nombre d’espèces de chauves-souris répertoriées sur le site. Pour les deux réserves, il est souhaitable de mener d’avantage d’études dans des habitats variés et à des saisons différentes. Des spécimens de référence et des échantillons de tissus devraient être collectés afin de faciliter les identifications de certaines espèces de Miniopterus. Il est également nécessaire d’estimer la disponibilité en insectes et en dortoirs à Berenty, à Beza Mahafaly et dans d’autres localités malgaches afin de déterminer les facteurs limitants de ces sites.

Abstract: The article gives an overview of the most well-known village fiddlers in Tori and V ndra parish, their repertoire, playing style and status as dance music players in the first half of the 20th century. This is one of the first efforts to try and describe Estonian traditional instrumental music from the inside so to say. First, the author learned to play the Estonian type of waltzes and polkas gathered from the local village musicians in her neighbourhood and used traditional method of learning by ear. Contact with the old fiddlers has been created artificially using the help of archive recordings datingback to the years 1936 and 1937. Following the personal experience of playing old fiddle tunes the author started transcribing and examining the tunes systematically.At that time both solo and duo performances were recorded from Tori and V ndra fiddlers. Those recordings compile the research material for the present article and on the basis of the recordings it is possible to describe how the fiddlers played back then. Transcriptions give an insight to the approach to form of the music and playing technique used in the fiddle tunes. Briefly, the body of those characteristics can be called the manner of playing the description of which introduces the musical thinking of village fiddlers and the overall characteristics of the performed music.What can be said to describe the traditional manner of playing based on the example of Tori and V ndra parish fiddlers? The districts of Tori and V ndra in the first half of the 20th century can be characterised by playing in fiddle duos. Compared to what was going on in Estonia of that time generally, it is not unique, because there were alsofiddle duos elsewhere. What is special about Tori and V ndra duos is how they wereplayed in. When playing in duos fiddlers used two different ways of playing. The first ofthem, one of the most characterising ones, is imitating bagpipe with fiddle, which wasonly used by Tori fiddlers. Imitating bagpipe is definitely one of the earliest of way ofplaying in terms of age in our old fiddle music. The other way of playing in duo performancesis simple polyphony based on functional harmony.Fiddlers made the melodies of Estonian type of waltzes and polkas more interestingand richer using polyphonic fiddle playing technique and embellishments of melodynotes. They used embellishments (mordents and upbeats) when they “felt like it”.Such means make a piece of music airy and general impression of the playing technique rather masterly.The structures of the analysed fiddle pieces are simpler and al
Everybody knows English? Language use in the world of learning

Abstract: This article will focus on the use of English as a global means of communication in higher education (HE) and research. The use of English is taken for granted as a global means of communication in the academic world. Therefore language issues are rarely problematized in science-policy contexts. This article will try to make the language issue visible by addressing aspects of a use of a lingua franca from a historical and pragmatic perspective and discuss its effects on everyday university life in non-Englishspeaking countries.
Pilk ingliskeelse kirjanduse t lgetele 18. sajandi l pust 20. sajandi algusveerandini / A Look at Estonian Translations of English Literature from the late 18th Century to the Early 20th Century

Abstract: The aim of this article is to provide an overview of translations of English literature into Estonian between 1779 and 1917. There is an attempt to analyse the texts by describing them on the basis of, or in their departure from, a text or texts that chronologically and logically precede them. The discussion includes the nature of the transfer and the changes that have been made to the text, either because they existed in the source or mediating text or because of the expectations or requirements in the receptor, i.e. Estonian culture. The translated texts are seen in their historical-cultural context. For the analysis, a corpus of translated texts – religious, fiction, drama and non-fiction (published in a book form) was compiled. The general orientation of Estonia until the 1880s was to the German cultural sphere. So the first translations of English literature were made via a mediating language, which was German. English Puritan writers were introduced by the Pietist missionaries with the aim of spreading their teachings in the second half of the 18th century. At about the same time the narrative element was introduced into stories with religious content. Some internationally popular stories, e.g. the Inkle and Yarico story, later robinsonades, stories of slavery and plant at ion life, as well as Amer ican Indian st or ies wer e also t r anslat ed fr om Ger man. However, until 1875 ver y few translations of English literature into E stonian were published. The last quarter of the 19th century saw an explosion in literary production: there was a substantial increase both in the number of translations of English literature into E stonian as well as diversification of genres. This continued into the first decade of the 20th centur y, when the sociopolitical situation in Estonia changed. In addition, books came to be translated directly from English, although many translations of English literature were still made via German and, to a lesser extent, via Russian, Swedish or Finnish. Thus, English literature often reached the Estonian audiences in a mediated form. The selection of authors and books, the structure of the texts and the overall meaning and tone of the texts often depended on the mediating text or culture. However, many changes were made by the translator: explanations of new words and phrases, pronunciations, references to the Estonian reader, etc. Here paratexts are quite important: the titles often explained the content or the purpose of the book and referred to the language from which the book was
Freedom from theory? An attempt to analyse Sten Karling’s views on (Estonian) art history
Krista Kodres
Journal of Art Historiography , 2010,
Abstract: This article focuses on a Swedish-born art historian Sten Ingvar Karling who was a professor in the Estonian national University of Tartu from 1933 to 1940. Karling published a great number of texts on local art history that were based on substantial archival inquiry, careful observation and stylistic systematisation of works of art. Karling’s discussions about the nature of art were brief and he hardly stressed the need for theoretical self-reflection. It is, however, obvious that his presentation and evaluation of artistic material was theory based. His ideas of art as an expression of 'will of art' and 'spirit of the time' and his views about change of styles mostly originated from the Vienna school of art history. At the same time he was a promoter of the concept of Baltic-Nordic artedominium, the construction that confronted the concept of German-dominated artistic past of the Baltic countries. Thus Karling’s logic of the 'construction of (Estonian) heritage' was coherent with the aim to strengthen one's own national identity through a new positive art historical narrative that took place intensively in the whole of Europe over the 1920-1930s.
