Lippu, uhri, kansakunta : Ryhmäkokemukset ja -rajat Suomessa 1917 1945

This dissertation deals with the notions of sacrifice and violence in connection with the Fin¬nish flag struggles between 1917 and 1945. The study begins with the basic idea that sacrificial thinking is a key element in nationalism and the social cohesion of large groups. The method used in the study combines anthropological notions of totemism with psychoanalytical object relation theory. The aim is to explore the social and psychological elements of the Finnish national flag and the workers flags during the times of crisis and nation building. The phenomena and concepts addressed include self-sacrifice, scapegoating, remembrance of war, inclusion, and exclusion. The research is located at the intersection of nationalism studies and the cultural history of war. The analysis is based primarily on the press debates, public speeches and archival sources of the civic organizations that promoted the Finnish flag. The study is empirically divided into three sections: 1) the years of the Revolution and the Civil War (1917 1918), 2) the interwar period (1919 1938), and 3) the Second World War (1939 1945). The research demonstrates that the modern national flags and workers flags in Finland maintain certain characteristics of primitive totems. When referred to as a totem the flag means an emotionally charged symbol, a reservoir of the collective ideals of a large group. Thus the flag issue offers a path to explore the perceptions and memory of sacrifice and violence in the making of the First Republic . Any given large group, for example a nation, must conceptually pursue a consensus on its past sacrifices. Without productive interpretation sacrifice represents only meaningless violence. By looking at the passions associated with the flag the study also illuminates various group identities, boundaries and crossings of borders within the Finnish society at the same time. The study shows further that the divisive violence of the Civil War was first overcome in the late 1930s when the social democrats adopted a new perception of the Red victims of 1918 they were seen as part of the birth pains of the nation, and not only the martyrs of class struggle. At the same time the radical Right became marginalized. The study also illuminates how this development made the Spirit of the Winter War possible, a genuine albeit brief experience of horizontal brother and sisterhood, and how this spirit was reflected in the popular adoption of the Finnish flag. The experience was not based only on the external and unifying threat posed by the Soviet Union: it was grounded in a sense of unifying sacrifice which reflected a novel way of understanding the nation and its past sacrifices. Paradoxically, the newly forged consensus over the necessity and the rewards of the common sacrifices of the Winter War (1939 1940) made new sacrifices possible during the Continuation War (1941 1944). In spite of political discord and war weariness, the concept of a unified nation under the national flag survived even the absurdity of the stationary war phase. It can be said that the conflict between the idea of a national community and parliamentary party politics dissolved as a result of the collective experience of the Second World War.

Foreign Capital and Finland : Central government's first period of reliance on international financial markets, 1862-1938

The main objective of the study is to evaluate the Finnish central government s foreign borrowing between the years 1862 and 1938. Most of this period was characterised by deep capital market integration that bears resemblance to the liberal world financial order at the turn of the millennium. The main aim is to analyse the credit risk associated with the state and its determination by evaluating the world financial market centres perception of Finland. By doing this, the study is also expected to provide an additional dimension to Finland s political and economic history by incorporating into the research the assessments of international capital markets regarding Finland during a period that witnessed profound political and economic changes in Finnish society. The evaluation of the credit risk mainly relies on exchange-rate risk free time series of the state s foreign bonds. They have been collected from quotations in the stock exchanges in Helsinki, Hamburg, Paris and London. In addition, it investigates Finland s exposure to short-term debt and Moody s credit ratings assigned to Finland. The study emphasises the importance of the political risk. It suggests that the hey-day of the state s reliance on foreign capital markets took place during last few decades of the 19th century when Finland enjoyed a wide autonomy in the Russian Empire and prudently managed its economy, highlighted in Finland s adherence to the international gold standard. Political confrontations in Finland and, in particular, in Russia and the turbulence of the world financial system prevented the return of this beneficial position again. Through its issuance of foreign bonds the state was able to import substantial amounts of foreign capital, which was sorely needed to foster economic development in Finland. Moreover, the study argues that the state s presence in the western capital markets not only had economic benefits, but it also increased the international awareness of Finland s distinct and separate status in the Russian Empire and later underlined its position as an independent republic.

Power and Distribution Network Structure in the People's Republic of China - The Case of an Inland City in Transition

The aim of the current study is to examine the influence of the channel external environment on power, and the effect of power on the distribution network structure within the People’s Republic of China. Throughout the study a dual research process was applied. The theory was constructed by elaborating the main theoretical premises of the study, the channel power theories, the political economy framework and the distribution network structure, but these marketing channel concepts were expanded with other perspectives from other disciplines. The main method applied was a survey conducted among 164 Chinese retailers, complemented by interviews, photographs, observations and census data from the field. This multi-method approach enabled not only to validate and triangulate the quantitative results, but to uncover serendipitous findings as well. The theoretical contribution of the current study to the theory of marketing channels power is the different view it takes on power. First, earlier power studies have taken the producer perspective, whereas the current study also includes a distributor perspective to the discussion. Second, many power studies have dealt with strongly dependent relationships, whereas the current study examines loosely dependent relationships. Power is dependent on unequal distribution of resources rather than based on high dependency. The benefit of this view is in realising that power resources and power strategies are separate concepts. The empirical material of the current study confirmed that at least some resources were significantly related to power strategies. The study showed that the dimension resources composed of technology, know-how and knowledge, managerial freedom and reputation was significantly related to non-coercive power. Third, the notion of different outcomes of power is a contribution of this study to the channels power theory even though not confirmed by the empirical results. Fourth, it was proposed that channel external environment other than the resources would also contribute to the channel power. These propositions were partially supported thus providing only partial contribution to the channel power theory. Finally, power was equally distributed among the different types of actors. The findings from the qualitative data suggest that different types of retailers can be classified according to the meaning the actors put into their business. Some are more business oriented, for others retailing is the only way to earn a living. The findings also suggest that in some actors both retailing and wholesaling functions emerge, and this has implications for the marketing channels structure.

Imazhinist Mariengof : Dendi. Montazh. Ciniki.

The study is dedicated to the Russian poet and prose writer Anatolii Borisovich Mariengof (1897–1962). Mariengof – “the last dandy of the Republic” – was one of the leaders and main theoreticians in the poetic group of the Russian Imaginists. For his contemporaries, he was an Imaginist par excellence. His Imaginist principles – in theory and practice – are applied to the study of his first fictional novel, Cynics (1928), which served as an epilogue for his Imaginist period (1918–1928). The novel was not published in the Soviet Union until 1988. The method used in the study is a conceptual and literary historical reading, making use of the contemporary semiotic understanding of cultural mechanisms and of intertextual analysis. There are three main concepts used throughout the study: dandy, montage and catachresis. In the first chapter, the history, practice and theory of the Russian Imaginism are analyzed from the point of view of dandyism. The Imaginist theatricalisation of life is juxtaposed with the thematic analysis of their poetry, and Imaginist dandyism appears as a catachrestic category in culture. The second chapter examines the Imaginist poetic theory. It is discussed in the context of the montage principle, defining the post-revolutionary culture in Soviet Russia. The Imaginist montage can be divided into three main theoretical paradigms: S. Yesenin’s “technical montage” (reminiscent of Dadaist collage), V. Shershenevich’s “nominative montage” (catalogues of images) and Anatolii Mariengof’s “catachrestic montage”. The final chapter deals with Mariengof’s first fictional novel, Cynics. The study begins with the complex history of publication of the novel, as well as its relation to the Imaginist poetic principles and to the history of the poetic movement. Cynics is, essentially, an Imaginist montage novel. The fragmentary play of the fictional and the documentary material follows the Imaginist montage principle. The chapter concludes in a thematic analysis of the novel, concentrating on the description of the October Revolution in Cynics.

Meillä ei ole ikuisia ystäviä eikä ikuisia vihollisia. Ikuisia ovat meidän omat etumme. : Suomen suhteet Kiinan kansantasavaltaan 1949 - 1989

"We have neither Eternal Friends nor Eternal Enemies. We have only Eternal Interests .Finland's Relations with China 1949-1989 The study focuses on the relations between Finland and the People s Republic of China from 1949-1989 and examines how a small country became embroiled in international politics, and how, at the same time, international politics affected Finnish-Chinese relations and Finland s China policy formulation. The study can be divided into three sections: relations during the early years, 1949-1960, before the Chinese and Soviet rift became public; the relations during the passive period during the 1960s and 1970s; and the impact of China s Open Door policy on Finland s China policy from 1978-1989. The diplomatically challenging events around Tiananmen Square and the reactions which followed in Finland bring the study to a close. Finland was among the first Western countries to recognise the People s Republic and to establish diplomatic relations with her, thereby giving Finland an excellent position from which to further develop good relations. Finland was also the first Western country to sign a trade agreement with China. These two factors meant that Finland was able to enjoy a special status with China during the 1950s. The special status was further strengthened by the systematic support of the government of Finland for China's UN membership. The solid reputation earned in the 1950s had to carry Finland all the way through to the 1980s. For the two decades in between, during the passive policy period of the 1960s and 1970s, relations between Finland and the Soviet Union also determined the state of foreign relations with China. Interestingly, however, it appeared that President Urho Kekkonen was encouraged by Ambassador Joel Toivola to envisage a more proactive policy towards China, but the Cultural Revolution cut short any such plan for nearly twenty years. Because of the Soviet Union, Finland held on to her passive China policy, even though no such message was ever received from the Soviet Union. In fact, closer relationships between Finland and China were encouraged through diplomatic channels. It was not until the presidency of Mauno Koivisto that the first high-level ministerial visit was made to China when, in 1984, Foreign Minister Paavo Väyrynen visited the People s Republic. Finnish-Chinese relations were lifted to a new level. Foreign Minister Väyrynen, however, was forced to remove the prejudices of the Chinese. In 1985, when the Speaker of the Finnish Parliament, Erkki Pystynen visited China he also discovered that Finland s passive China policy had caused misunderstandings amongst the Chinese politicians. The number of exchanges escalated in the wake of the ground-breaking visit by Foreign Minister Väyrynen: Prime Minister Kalevi Sorsa visited China in 1986 and President Koivisto did so in 1988. President Koivisto stuck to practical, China-friendly policies: his correspondence with Li Peng, the attitude taken by the Finnish government after the Tiananmen Square events and the subsequent choices made by his administration all pointed to a new era in relations with China.

The Development of the Concept of Music Education in Estonian Kindergartens, 1905-2008 : a Historical–Critical Overview

The dissertation focuses on the development of music education in Estonian kindergartens and the factors influencing it, analysed in the historical perspective relying on post-positivist paradigm. The study is based on the factors and subjects’ views on kindergarten music education from 1905 to 2008, recorded in written sources or ascertained by means of questionnaire and interview. The dissertation deals with music’s functions, music education in retrospective, factors influencing child’s musical aptitude and development and teacher’s role in it through the prism of history. The formation of Estonian kindergarten music education and the phenomenon of its development have been researched by stages: the first manifestations of music in kindergarten in 1905 - 1940; the formation of the concept of music education in 1941 - 1967 and the application of a unified system in 1968 - 1990. The work also outlines innovative trends in music education at the end of the last millennium and the beginning of this century, in 1991 - 2008. The study relies on a combined design and an analysis of historical archival material and empirical data. The empirical part of the study is based on the questionnaire (n=183) and interviews (n=18) carried out with kindergarten music teachers. The data has been analysed using both qualitative and quantitative methods. The subject of the research is the content and activity types of kindergarten music education and the role of music teacher in their implementation. The study confirmed that fundamental changes took place in Estonian kindergarten music education due to the change in political power in the 1940s. Following the example of the Soviet system of education, music in kindergarten became an independent music educational orientation and the position of a professionally trained music teacher was established (1947). It was also confirmed that in the newly independent Estonian Republic under the influence of innovative trends a new paradigm of music education arose from the traditional singing-centred education towards the more balanced use of music activity types (attaching importance to the child-centred approach, an increase in the number and variety of activity types). The most important conclusions made in the dissertation are that there has been improvement and development deriving from contemporary trends in the clear concept that has evolved in Estonian kindergarten music education over a century; professionally trained music teachers have had a crucial role in shaping it; and kindergarten music education is firmly positioned as a part of preschool education in Estonian system of education. Key words: early childhood music education, history of music education, kindergarten music education, early childhood music teachers

The epidemiology of severe Streptococcus pyogenes disease in Europe

Diseases caused by the Lancefield group A streptococcus, Streptococcus pyogenes, are amongst the most challenging to clinicians and public health specialists alike. Although severe infections caused by S. pyogenes are relatively uncommon, affecting around 3 per 100,000 of the population per annum in developed countries, the case fatality is high relative to many other infections. Despite a long scientific tradition of studying their occurrence and characteristics, many aspects of their epidemiology remain poorly understood, and potential control measures undefined. Epidemiological studies can play an important role in identifying host, pathogen and environmental factors associated with risk of disease, manifestation of particular syndromes or poor survival. This can be of value in targeting prevention activities, as well directing further basic research, potentially paving the way for the identification of novel therapeutic targets. The formation of a European network, Strep-EURO, provided an opportunity to explore epidemiological patterns across Europe. Funded by the Fifth Framework Programme of the European Commission s Directorate-General for Research (QLK2.CT.2002.01398), the Strep-EURO network was launched in September 2002. Twelve participants across eleven countries took part, led by the University of Lund in Sweden. Cases were defined as patients with S. pyogenes isolated from a normally sterile site, or non-sterile site in combination with clinical signs of streptococcal toxic shock syndrome (STSS). All participating countries undertook prospective enhanced surveillance between 1st January 2003 and 31st December 2004 to identify cases diagnosed during this period. A standardised surveillance dataset was defined, comprising demographic, clinical and risk factor information collected through a questionnaire. Isolates were collected by the national reference laboratories and characterised according to their M protein using conventional serological and emm gene typing. Descriptive statistics and multivariable analyses were undertaken to compare characteristics of cases between countries and identify factors associated with increased risk of death or development of STSS. Crude and age-adjusted rates of infection were calculated for each country where a catchment population could be defined. The project succeeded in establishing the first European surveillance network for severe S. pyogenes infections, with 5522 cases identified over the two years. Analysis of data gathered in the eleven countries yielded important new information on the epidemiology of severe S. pyogenes infections in Europe during the 2000s. Comprehensive epidemiological data on these infections were obtained for the first time from France, Greece and Romania. Incidence estimates identified a general north-south gradient, from high to low. Remarkably similar age-standardised rates were observed among the three Nordic participants, between 2.2 and 2.3 per 100,000 population. Rates in the UK were higher still, 2.9/100,000, elevated by an upsurge in drug injectors. Rates from these northern countries were reasonably close to those observed in the USA and Australia during this period. In contrast, rates of reports in the more central and southern countries (Czech Republic, Romania, Cyprus and Italy) were substantially lower, 0.3 to 1.5 per 100,000 population, a likely reflection of poorer uptake of microbiological diagnostic methods within these countries. Analysis of project data brought some new insights into risk factors for severe S. pyogenes infection, especially the importance of injecting drug users in the UK, with infections in this group fundamentally reshaping the epidemiology of these infections during this period. Several novel findings arose through this work, including the high degree of congruence in seasonal patterns between countries and the seasonal changes in case fatality rates. Elderly patients, those with compromised immune systems, those who developed STSS and those infected with an emm/M78, emm/M5, emm/M3 or emm/M1 were found to be most likely to die as a result of their infection, whereas those diagnosed with cellulitis, septic arthritis, puerperal sepsis or with non-focal infection were associated with low risk of death, as were infections occurring during October. Analysis of augmented data from the UK found use of NSAIDs to be significantly associated with development of STSS, adding further fuel to the debate surrounding the role of NSAIDs in the development of severe disease. As a largely community-acquired infection, occurring sporadically and diffusely throughout the population, opportunities for control of severe infections caused by S. pyogenes remain limited, primarily involving contact chemoprophylaxis where clusters arise. Analysis of UK Strep-EURO data were used to quantify the risk to household contacts of cases, forming the basis of national guidance on the management of infection. Vaccines currently under development could offer a more effective control programme in future. Surveillance of invasive infections caused by S. pyogenes is of considerable public health importance as a means of identifying long and short-term trends in incidence, allowing the need for, or impact of, public health measures to be evaluated. As a dynamic pathogen co-existing among a dynamic population, new opportunities for exploitation of its human host are likely to arise periodically, and as such continued monitoring remains essential.

Venäjän politiikka ja perustuslaki : Tutkimus Venäjän perustuslakikäsitteistön kehityksestä 1900-luvulla

Constitutional politics in Russia, a conceptual history study of the constitutional rhetoric in the 20th century In April 2006 the Russian Constitution had its 100th anniversary. Following its late start, five constitutions have been adopted. The great number of constitutions is partly explained in my work by the fact that Russia s political system has changed many times, from one state system to another. From a monarchical state power, it changed first, with the October revolution, into the Russian Socialist Federal Soviet Republic, and after that, in 1924, into the Union of Soviet Socialist Republics. In 1991, the Russian Federation was established. The great number of constitutions can also be explained by the fact that in a one-party system, constitutional concepts became one of the most important instruments for introducing political programmes. When the political unity of the state was not only restricted by the Constitution, but also by the party ideology, the political debates concerning constitutional concepts were the key discussions for all the reformative pursuits of Soviet politics. It can be said that, in the Soviet Union, almost all political discourses dealt with constitutional concepts. In the context of restricted unity, the constitutional concepts were the most important tools to argue and create a basis for a new presentation and new political programmes. Thus, the basic feature of the Soviet political discourses has been a continuous competition regarding the constitutional concepts. By defining the constitutional concepts, a new, the political elites wanted especially to redefine, their own way, the traditional meanings of the October 1917 Revolution, and to differentiate them from those of the preceding period of power. From a methodological point of view, I argue that the Russian constitutional concepts make a conceptual historical approach very suitable, and change the focus on history. This approach studies history in contemporary contexts which follow after each other, and whose texts are the main research target. The picture of history is created through the interpretation of the original sources of contemporary contexts. Focusing on the dynamic and traditional characteristic of Russian constitutional concepts, I refer to a certain kind of value and the task of these concepts to justify and define the political and societal unity in every situation. This is done by combining the pursued future orientation of constitutional unity with the new acts of preservation of the traditional principles of the revolution. The different time layers of the constitutional concepts, the past, the present and the future, are the key aspects of storytelling in justifying the continuity and redefining the constitutional unity for the sake of reform. These aspects of constitutional concepts, in addition to all the other functions, have been the main elements of the argumentative structure of acting against opponents.

Observations on the first steps of atmospheric particle formation and growth

Atmospheric aerosol particles have a significant impact on air quality, human health and global climate. The climatic effects of secondary aerosol are currently among the largest uncertainties limiting the scientific understanding of future and past climate changes. To better estimate the climatic importance of secondary aerosol particles, detailed information on atmospheric particle formation mechanisms and the vapours forming the aerosol is required. In this thesis we studied these issues by applying novel instrumentation in a boreal forest to obtain direct information on the very first steps of atmospheric nucleation and particle growth. Additionally, we used detailed laboratory experiments and process modelling to determine condensational growth properties, such as saturation vapour pressures, of dicarboxylic acids, which are organic acids often found in atmospheric samples. Based on our studies, we came to four main conclusions: 1) In the boreal forest region, both sulphurous compounds and organics are needed for secondary particle formation, the previous contributing mainly to particle formation and latter to growth; 2) A persistent pool of molecular clusters, both neutral and charged, is present and participates in atmospheric nucleation processes in boreal forests; 3) Neutral particle formation seems to dominate over ion-mediated mechanisms, at least in the boreal forest boundary layer; 4) The subcooled liquid phase saturation vapour pressures of C3-C9 dicarboxylic acids are of the order of 1e-5 1e-3 Pa at atmospheric temperatures, indicating that a mixed pre-existing particulate phase is required for their condensation in atmospheric conditions. The work presented in this thesis gives tools to better quantify the aerosol source provided by secondary aerosol formation. The results are particularly useful when estimating, for instance, anthropogenic versus biogenic influences and the fractions of secondary aerosol formation explained by neutral or ion-mediated nucleation mechanisms, at least in environments where the average particle formation rates are of the order of some tens of particles per cubic centimeter or lower. However, as the factors driving secondary particle formation are likely to vary depending on the environment, measurements on atmospheric nucleation and particle growth are needed from around the world to be able to better describe the secondary particle formation, and assess its climatic effects on a global scale.

Cultural Trauma and Life Stories

The purpose of this work is to use the concepts of human time and cultural trauma in a biographical study of the turning points in the recent history of Estonia. This research is primarily based on 148 in-depth biographical interviews conducted in Estonia and Sweden in 1995-2005, supplemented by excerpts from 5 collections and 10 individually published autobiographies. The main body of the thesis consists of six published and of two forthcoming separate refereed articles, summarised in the theoretical introduction, and Appendix of the full texts of three particular life stories. The topic of the first article is the generational composition and the collective action frames of anti-Soviet social mobilisation in Estonia in 1940-1990. The second article details the differentiation of the rites of passage and the calendar traditions as a strategy to adapt to the rapidly changed political realities, comparatively in Soviet Estonia and among the boat-refugees in Sweden. The third article investigates the life stories of the double-minded strategic generation of the Estonian-inclined Communists, who attempted to work within the Soviet system while professing to uphold the ideals of pre-war Estonia. The fourth article is concentrated on the problems of double mental standards as a coping strategy in a contradictory social reality. The fifth article implements the theory of cultural trauma for the social practice of singing nationalism in Estonia. The sixth article bridges the ideas of Russian theoreticians concerning cultural dialogue and the Western paradigm of cultural trauma, with examples from Estonian Russian life stories. The seventh article takes a biographical look at the logic of the unraveling of cultural trauma through four Soviet decades. The eighth article explores the re-shaping of citizen activities as a strategy of coping with the loss of the independent nation state, comparatively in Soviet Estonia and among Swedish Estonians. Cultural trauma is interpreted as the re-ordering of the society s value-normative constellation due to sharp, violent, usually political events. The first one under consideration was caused by the occupations of the Republic of Estonia by the Soviet army in 1940-45. After half a century of suppression the memories of these events resurfaced as different stories describing the long-term, often inter-generational strategies of coping with the value collapse. The second cultural trauma is revealed together with the collapse of the Soviet power and ideology in Estonia in 1991. According to empirical data, the following three trauma discourses have been reconstructed: - the forced adaptation to Soviet order of the homeland Estonians; - the difficulty of preserving Estonian identity in exile (Sweden); - the identity crisis of the Russian population of Estonia. Comparative analyses of these discourses have shown that opposing experiences and worldviews cause conflicting interpretations of the past. Different social and ethnic groups consider coping with cultural trauma as a matter of self-defence and create appropriate usable pasts to identify with. Keywords: human time, cultural trauma, frame analysis, discourse, life stories

First Measurement of the Ratio of Branching Fractions B(Lambda_b to Lambda_c mu nu)/B(Lambda_b to Lambda_c pi)

The analysis uses data from an integrated luminosity of approximately 172 pb-1 of ppbar collisions at sqrt(s)=1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. The Lambda_b and B0 relative branching fractions are measured to be: B(Lambda_b to Lambda_c+ mu nu)/B(Lambda_b to Lambda_c+ pi) = 16.6 +- 3.0 (stat) +- 1.0 (syst) +2.6 -3.4 (PDG) +- 0.3 (EBR), B(B0 to D+ mu nu)/B(B0 to D+ pi) = 9.9 +- 1.0 (stat) +- 0.6 (syst) +- 0.4 (PDG) +- 0.5 (EBR), B(B0 to D*+ mu nu)/B(B0 to D*+ pi) = 16.5 +- 2.3 (stat) +- 0.6 (syst) +- 0.5 (PDG) +- 0.8 (EBR) This article also presents measurements of the branching fractions of four new Lambda_b semileptonic decays: Lambda_b to Lambda_c(2595)+ mu nu, Lambda_b to Lambda_c(2625)+ mu nu, Lambda_b to Sigma_c(2455)0 pi mu nu, Lambda_b to Sigma_c(2455)++ pi mu nu, relative to the branching fraction of the Lambda_b to Lambda_c mu nu decay. Finally, the transverse-momentum distribution of Lambda_b baryons produced in p-pbar collisions is measured and found to be significantly different from that of B0 mesons.

First observation of the decay Bs --> Ds K and measurement of the ratio of branching fractions Br(Bs --> DsK)/Br(Bs --> Ds pi)

A combined mass and particle identification fit is used to make the first observation of the decay Bs --> Ds K and measure the branching fraction of Bs --> Ds K relative to Bs --> Ds pi. This analysis uses 1.2 fb^-1 integrated luminosity of pbar-p collisions at sqrt(s) = 1.96 TeV collected with the CDF II detector at the Fermilab Tevatron collider. We observe a Bs --> Ds K signal with a statistical significance of 8.1 sigma and measure Br(Bs --> Ds K)/Br(Bs --> Ds pi) = 0.097 +- 0.018(stat) +- 0.009(sys).

First Measurement of the b-Jet Cross Section in Events with a W Boson in pp̅ Collisions at √s=1.96 TeV

The cross section for jets from b quarks produced with a W boson has been measured in ppbar collision data from 1.9/fb of integrated luminosity recorded by the CDF II detector at the Tevatron. The W+b-jets process poses a significant background in measurements of top quark production and prominent searches for the Higgs boson. We measure a b-jet cross section of 2.74 +- 0.27(stat.) +- 0.42(syst.) pb in association with a single flavor of leptonic W boson decay over a limited kinematic phase space. This measured result cannot be accommodated in several available theoretical predictions.
