Measurement of the Top Quark Mass with a Matrix Element Method in the Lepton Plus Jets Channel at CDF

We present a measurement of the mass of the top quark from ppbar collisions at 1.96 TeV observed with the Collider Detector at Fermilab (CDF) at the Fermilab Tevatron Run II. The events have the decay signature of ppbar to ttbar in the lepton plus jets channel in which at least one jet is identified as coming from a secondary vertex and therefore a b-hadron. The largest systematic uncertainty, the jet energy scale (JES), is convoluted with the statistical error using an in-situ measurement of the hadronic W boson mass. We calculate a likelihood for each event using leading-order ttbar and W+jets cross-sections and parameterized parton showering. The final measured top quark mass and JES systematic is extracted from a joint likelihood of the product of individual event likelihoods. From 118 events observed in 680 pb-1 of data, we measure a top quark mass of 174.09 +- 2.54 (stat+JES) +- 1.35 (syst) GeV/c2.Comment: Proceedings for the 41st Rencontres de Moriond, EWK, March 11 - 28, 2006. 4 pages, 1 figur

Precise measurement of the top quark mass from lepton+jets events at D0

We measure the mass of the top quark using top quark pair candidate events in the lepton+jets channel from data corresponding to 1 fb-1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron collider. We use a likelihood technique that reduces the jet energy scale uncertainty by combining an in-situ jet energy calibration with the independent constraint on the jet energy scale (JES) from the calibration derived using photon+jets and dijet samples. We find the mass of the top quark to be 171.5+-1.8(stat.+JES)+-1.1(syst.) GeV.Comment: submitted to Phys. Rev. Letter

Exploring the Virulent Jazz Counterculture in Mumbo Jumbo

This article will be focusing on Ishmael Reed’s Mumbo Jumbo (1972), a vibrant postmodernist text, which offers a fresh perspective on the rise of black popular culture in the form of Jes Grew, which is largely informed by jazz and neo-hoodoo aesthetics. Jes Grew, the phenomenon which binds the multifaceted text in cohesion and brings together elements from History, Jazz and Afrofuturism, is communicated by using the metaphor of a virulent disease- the Jes Grew pandemic. The article is a work in cultural studies, attempting to map the evolution of the counter culture that Jes Grew represents and its effect on identity. This mapping is achieved by viewing the equation of the Jazz counter-culture with the Jes Grew pandemic. Jes Grew decodes the cultural and racial politics Mumbo Jumbo is invested in by destabilising the meaning and perspective attached to ‘disease’ and adapting it to an entirely new climate of cultural reclamation and celebration by deconstructing the dominant culture defined illness (Jes Grew in the text) and reinterpreting it as potentially healing and liberating. The discussion of the politics and aesthetics of this counter-culture mainly hinges on the central metaphor of the Jes Grew pandemic operating throughout the narrative. Raymond Williams’ work on culture studies and Stuart Hall’s theory on the formation and representation of cultural identities are particularly helpful in discussing the issues of culture and identity that are in dialogue with the narrative

O papel da orientação para o mercado e orientação empreendedora no desempenho das júnior empresas

This study explores the market orientation (MO), entrepreneurial orientation (EO) and its relationship with the performance of Junior Enterprises (JEs). Using a sample of 93 Junior Enterprises, we tested the suitability of the MO and EO scales proposed by Kohli, Jaworski, and Kumar (1993) and Hughes and Morgan (2007) respectively, and new dimensions and scales were created that better fit JEs characteristics. With these new dimensions, we tested the effect of MO and EO on performance and the mediating effect of EO between MO and performance. Results suggest that both MO and EO dimensions have a positive impact on JEs’ performance and that EO dimensions partially or totally mediate the link between MO dimensions and performance. The study provides a more detailed understanding of JEs organizational characteristics and the impact of strategic orientations in their performance, providing, on the one hand, implications for research through the analysis of these constructs in a new context and through the analysis of EO as mediator. On the other hand, implications for JEs and national/international federations that can adapt their strategies and training plans bearing in mind these topics, as well as for universities that can better understand the context and potential of JEs and thus support them more effectively.Este estudo explora a orientação para o mercado (MO), a orientação empreendedora (EO) e as suas relações com o desempenho das Júnior Empresas (JEs). Utilizando uma amostra de 93 Júnior Empresas, foi testada a adequação das escalas MO e EO propostas por Kohli, Jaworski, and Kumar (1993) e Hughes and Morgan (2007) respetivamente, tendo sido criadas novas dimensões e escalas que melhor se adequam às características das JEs. Com estas novas dimensões, foi testado o efeito de MO e EO no desempenho das JEs e o efeito mediador de EO na relação entre MO e desempenho. Os resultados sugerem que tanto as dimensões de MO e como de EO têm um impacto positivo no desempenho das JEs e que as dimensões de EO mediam, parcial ou totalmente, a ligação entre as dimensões de MO e o desempenho. Este estudo oferece um entendimento mais detalhado das características das JEs e o impacto das orientações estratégicas no seu desempenho, fornecendo por um lado implicações para a investigação pela análise destes constructos num novo contexto e pela análise de EO como mediador, algo pouco discutido na literatura. Por outro lado, implicações para as JEs e federações nacionais e internacionais que podem assim adaptar as suas estratégias e planos de formação tendo em conta estes tópicos, bem como para as universidades que podem perceber melhor o contexto e potencial das JEs e assim apoiar estas mais eficazmente.FCT - PTDC/IVC-PEC/5514/2014Mestrado em Gestã

Clem Johnson\u27s General Store

I reckon that that there buildin\u27 across the way jes\u27 looks like a pile of old boards to you folks, the old man at the filling station said as he wiped the car windows. I looked across the road and saw what seemed to be a dingy, run-down loafing place for all the idlers and farmers of the community. Well, it ain\u27t what you\u27re a-thinkin\u27, ma\u27am. That store is Clem\u27s whole life. See, you can tell it\u27s Clem\u27s store \u27cause it says so right up over the door in big red letters, Clem Johnson\u27s General Store. \u27Course, now the sign\u27s kinda faded \u27cause it ain\u27t been painted for nearly twenty years or so, jes\u27 like the whole dern buildin\u27. Clem\u27s been a-managin\u27 that store ever since his pa died when Clem was eighteen. It used to be a right-nice lookin\u27 place
