Book Synopsis Large Pt Processes in Ppbar Collisions at 2 TeV by : Ashish Kumar
Download or read book Large Pt Processes in Ppbar Collisions at 2 TeV written by Ashish Kumar and published by . This book was released on 2005 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The measurement of the top-antitop pair production cross section in p{bar p} collisions at {radical}s = 1.96 TeV in the dielectron decay channel using 384 pb{sup -1} of D0 data yields a t{bar t} production cross-section of {sigma}{sub t{bar t}} = 7.9{sub -3.8}{sup +5.2}(stat){sub -1.0}{sup +1.3}(syst) {+-} 0.5 (lumi) pb. This measurement [98] is based on 5 observed events with a prediction of 1.04 background events. The cross-section corresponds to the top mass of 175 GeV, and is in good agreement with the Standard Model expectation of 6.77 {+-} 0.42 pb based on next-to-next-leading-order (NNLO) perturbative QCD calculations [78]. This analysis shows significant improvement from our previous cross-section measurement in this channel [93] with 230 pb{sup -1} dataset in terms of significantly better signal to background ratio and uncertainties on the measured cross-section. Combination of all the dilepton final states [98] yields a yields a t{bar t} cross-section of {sigma}{sub t{bar t}} = 8.6{sub -2.0}{sup +2.3}(stat){sub -1.0}{sup +1.2}(syst) {+-} 0.6(lumi) pb, which again is in good agreement with theoretical predictions and with measurements in other final states. Hence, these results show no discernible deviation from the Standard Model. Fig. 6.1 shows the summary of cross-section measurements in different final states by the D0 in Run II. This measurement of cross-section in the dilepton channels is the best dilepton result from D0 till date. Previous D0 result based on analysis of 230 pb{sup -1} of data (currently under publication in Physics Letters B) is {sigma}{sub t{bar t}} = 8.6{sub -2.7}{sup +3.2}(stat){sub -1.1}{sup +1.1}(syst) {+-} 0.6(lumi) pb. It can be seen that the present cross-section suffers from less statistical uncertainty. This result is also quite consistent with CDF collaboration's result of {sigma}{sub t{bar t}} = 8.6{sub -2.4}{sup +2.5}(stat){sub -1.1}{sup +1.1}(syst) pb. These results have been presented as D0's preliminary results in the high energy physics conferences in the Summer of 2005 (Hadron Collider Physics Symposium, European Physical Society Conference, etc.). The uncertainty on the cross-section is still dominated by statistics due to the small number of observed events. It can be seen that we are at a level where statistical uncertainties are becoming closer to the systematic ones. Future measurements of the cross section will benefit from considerably more integrated luminosity, leading to a smaller statistical error. Thus the next generation of measurements will be limited by systematic uncertainties. Monte Carlo samples with higher statistics are also being generated in order to decrease the uncertainty on the background estimation. In addition, as the jet energy scale, the electron energy scale, the detector resolutions, and the luminosity measurement are fine-tuned, the systematic uncertainties will continue to decrease.

Book Synopsis Changing Concepts of Contract by : David Campbell
Download or read book Changing Concepts of Contract written by David Campbell and published by Springer. This book was released on 2017-02-28 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing Concepts of Contract is a prestigious collection of essays that re-examines the remarkable contributions of Ian Macneil to the study of contract law and contracting behaviour. Ian Macneil, who taught at Cornell University, the University of Virginia and, latterly, at Northwestern University, was the principal architect of relational contract theory, an approach that sought to direct attention to the context in which contracts are made. In this collection, nine leading UK contract law scholars re-consider Macneil's work and examine his theories in light of new social and technological circumstances. In doing so, they reveal relational contract theory to be a pertinent and insightful framework for the study and practice of the subject, one that presents a powerful challenge to the limits of orthodox contract law scholarship. In tandem with his academic life, Ian Macneil was also the 46th Chief of the Clan Macneil. Included in this volume is a Preface by his son Rory Macneil, the 47th Chief, who reflects on the influences on his father's thinking of those experiences outside academia. The collection also includes a Foreword by Stewart Macaulay, Malcolm Pitman Sharp Hilldale Professor Emeritus at the University of Wisconsin-Madison, and an Introduction by Jay M Feinman, Distinguished Professor of Law at Rutgers School of Law.
Book Synopsis Advances in Critical Discourse Studies by : John Richardson
Download or read book Advances in Critical Discourse Studies written by John Richardson and published by Routledge. This book was released on 2016-03-16 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Critical Discourse Studies collects ground-breaking scholarship and cutting-edge research which reflects significant shifts in Critical Discourse Studies, exploring the field from theoretical, analytic and methodological perspectives. Innovative chapters analyse a diverse range of discourses including journalism, mass media, political communication, policy documents, interviews, photographic archive and official bodies. The chapters in Part I explore Critical Discourse Studies from the point of view of history, memory, identity politics, and discourse, analysing salient examples of how memory and recollection of the past shapes understandings and narratives of the present, and visions of future societies. Part II explores problem-oriented analysis in Critical Discourse Studies and examines the roles that discourse plays in the formation, perpetuation and transformation of class relations. Finally, Part III explores a methodological issue by looking at the benefits of reinforcing fieldwork and ethnographic analysis in Critical Discourse Studies. The case studies throughout the book demonstrate that analytic research contributes significantly to the in-depth and in-situ research of a variety of increasingly complex social, historical, political and economic contexts. This book was originally published as three special issues of the journal Critical Discourse Studies.

Book Synopsis Chinese Politics and International Relations by : Nicola Horsburgh
Download or read book Chinese Politics and International Relations written by Nicola Horsburgh and published by Routledge. This book was released on 2014-01-03 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of how China will relate to a globalising world is one of the key issues in contemporary international relations and scholarship on China, yet the angle of innovation has not been properly addressed within the field. This book explores innovation in China from an International Relations perspective in terms of four areas: foreign and security policy, international relations theory, soft power/image management, and resistance. Under the complex condition of globalisation, innovation becomes a particularly useful analytical concept because it is well suited to capturing the hybridity of actors and processes under globalisation. By adopting this theme, studies not only reveal a China struggling to make the future through innovation, but also call attention to how China itself is made in the process. The book is divided into four sections: Part 1 focuses on conceptual innovation in China’s foreign and security policies since 1949. Part 2 explores theoretical innovation in terms of a potential Chinese school of International Relations Theory. Part 3 expands on innovation in terms of image management, a form of soft power, in particular how China exports its image both to a domestic and foreign audience. Part 4 highlights how innovation is used in China by grassroot popular groups to resist official narratives. This book will be of interest to students and scholars of Chinese studies, Chinese foreign policy and international relations, international relations theory and East Asian security.
Book Synopsis Learning Platforms and Learning Outcomes by : Don Passey
Download or read book Learning Platforms and Learning Outcomes written by Don Passey and published by Routledge. This book was released on 2016-04-08 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides contemporary insights into learning outcomes arising from the use of learning platforms by pupils, students and teachers in schools. Most current research focuses on the implementation of learning platforms, and the ways in which practices are developing over time, or in specific contexts. This collection offers a range of contrasting but complementary perspectives in this area, including an exploration of applications supporting management of learning across primary and secondary schools in the UK, an in-depth case study of uses and outcomes in a school in Singapore, an analysis of learning outcomes arising across primary, special and secondary schools in one local authority in the UK, and a look at student preferences for using a learning platform in a school in Taiwan. The volume sheds important light on the subject, but with the ever changing development and introduction of learning platforms, much remains to be explored. Indeed, it is likely that learning platforms will evolve further with affordances and integrated features being added over the next five and more years. This work hints at future practices and their potential outcomes, pointing to the need for greater detail being gathered through future research studies, in order to understand ways teachers and learners might most effectively benefit from more holistic or ‘blended’ approaches across the applications provided. This book will not only be of particular interest to those involved in using learning platforms, but also to those advising on, and developing, learning platforms. Key lessons and issues are of relevance to policy makers, school managers and teachers, educational advisers, researchers and developers. This book was originally published as a special issue of Learning, Media and Technology.

Book Synopsis Gender and Language in Sub-Saharan Africa by : Lilian Lem Atanga
Download or read book Gender and Language in Sub-Saharan Africa written by Lilian Lem Atanga and published by John Benjamins Publishing. This book was released on 2013-03-27 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gender and Language in Sub-Saharan Africa: Tradition, Struggle and Change is the first book to bring together the topics of language and gender, African languages, and gender in African contexts, and it does so in a descriptive, explanatory and critical way. Including fascinating new work and new, often challenging data from Botswana, Chad, Ghana, Kenya, Nigeria and South Africa, this collection looks at some ‘traditional’ uses of language in relation to the gender of its speakers and the gendered nature of the languages themselves; it also identifies and explores social change in terms of both gender and sexuality, as reflected in and constructed by language and discourse. The contributions to this volume are accessibly written and will be of interest to students and established academics working on African sociolinguistics and discourse, as well as those whose interest is language, gender and sexuality.
Download or read book Persistent Ruskin written by Keith Hanley and published by Routledge. This book was released on 2016-05-13 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examining the wide-ranging implications of Ruskin's engagement with his contemporaries and followers, this collection is organized around three related themes: Ruskin's intellectual legacy and the extent to which its address to working men and women and children was realised in practice; Ruskin's followers and their sites of influence, especially those related to the formation of collections, museums, archives and galleries representing values and ideas associated with Ruskin; and the extent to which Ruskin's work constructed a world-wide network of followers, movements and social gestures that acknowledge his authority and influence. As the introduction shows, Ruskin's continuing digital presence is striking and makes a case for Ruskin's persistent presence. The collection begins with essays on Ruskin's intellectual presence in nineteenth-century thought, with some emphasis on his interest in the education of women. This section is followed by one on Ruskin's followers from the mid-nineteenth century into twentieth-century modernism that looks at a broad range of cultural activities that sought to further, repudiate, or exemplify Ruskin's work and teaching. Working-class education, the Ruskinian periodical, plays, and science fiction are all considered along with the Bloomsbury Group's engagement with Ruskin's thought and writing. Essays on Ruskin abroad-in America, Australia, and India round out the collection.
Book Synopsis Does it Pay to Have Friends? - Social Ties and Executive Appointments in Banking by : Allen N. Berger
Download or read book Does it Pay to Have Friends? - Social Ties and Executive Appointments in Banking written by Allen N. Berger and published by . This book was released on 2014 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: We exploit a unique sample to analyze how homophily (affinity for similar others) and social ties affect career outcomes in banking. We test if these factors increase the probability that the appointee to an executive board is an outsider without previous employment at the bank compared to being an insider. Homophily based on age and gender increase the chances of the outsider appointments. Similar educational backgrounds, in contrast, reduce the chance that the appointee is an outsider. Greater social ties also increase the probability of an outside appointment. Results from a duration model show that larger age differences shorten tenure significantly, whereas gender similarities barely affect tenure. Differences in educational backgrounds affect tenure differently across the banking sectors. Maintaining more contacts to the executive board reduces tenure. We also find weak evidence that social ties are associated with reduced profitability, providing some evidence of cronyism in banking.
