E-BASS25 Work Package 5 - Procurement Guidelines
Full text linkThe purpose of this work package is to engage with procurement professionals from
University purchasing consortia and JISC Collections to identify the potential procurement
options when establishing a Consortial e-books agreement. It also seeks to provide guidelines
for library acquisitions managers who are considering the various routes for procuring EBook
Development of a new Soft Muon Tagger for the Identification of b quarks, applied to a Top Quark Pair Production Cross Section Measurement, using the ATLAS Detector at CERN.
No full textThis thesis presents a study of a method for identifying b-jets by searching for “soft” muons produced within them. This method, a so-called Soft Muon Tagger, uses the quality of the match (Χ2match) between tracks left in the inner detector and the muon systems within the ATLAS detector to discriminate between muons within hadronic jets produced by the decay of b quarks, and those within light flavour jets.
The complete characteristics of the tagger are investigated in a detailed study on simulated data. The scale factors between the efficiency of the tagger in simulated and collision data, dependent on the kinematics of the tagged muon, are found using J/Ψ decays. These are used in a measurement of the top quark pair production cross section in collision data.
The measurement is performed on data taken during the 2011 run of the LHC, specifically in the lepton+jets top-antitop quark decay channel. A summary of this measurement is presented, and is found to be compatible with theoretical predictions for the cross section at a centre of mass energy of √s = 7 TeV, and with published ATLAS and CMS measurements using b-tagging in the lepton+jets channel. The measured cross section is:
σtt ̄ = 165 ± 2(stat.) ± 17(syst.) ± 3(lumi.) pb
The Χ2match-based soft muon tagger contributes a small b-tagging systematic uncertainty to the cross section measurement compared to measurements performed using lifetime based b-taggers, and has a good signal to background ratio
A Betrayed Promise? The Politics of the Everyday State and the Resettling of Refugees in Pakistani Punjab, 1947-1962
No full textLahore, Anarkali, mid-1950s. A distinguished-looking refugee is standing in front of a petition writer in the hope of getting the better of the Pakistani bureaucracy and having a property allotted. A few miles ahead, another refugee, camped in a school, is drafting a letter to the editor of the Pakistan Times. He will hide his identity through the pseudonym ‘desperate’. Both of them belonged to the throng of those muhajirs who, back in 1947, had embarked on a dreadful journey towards what they perceived to be their homeland. Historiographical trends have tended to overlook the everyday experience of the state among those middle-class Partition refugees who resettled in Pakistani Punjab. Focusing mainly on their ‘less fortunate’ fellow citizens, these explanations have reproduced that historically-unproven popular narrative that ascribes pain and sufferings only to the economically-backward sectors of the local society. Even more frequently, well-rooted argumentative patterns have superimposed historical and present-day socio-geographical mappings of refugee families onto both urban and rural Punjab. These somehow echo that government rhetoric that, up to the early 1960s, paid lip service to the notion of a ‘biraderi-friendly’ rehabilitation. This thesis challenges standard interpretations of the resettlement of Partition refugees in Pakistani Punjab between 1947 and 1962. It argues the universality of the so-called ‘exercise in human misery’, and the heterogeneity of the rehabilitation policies. As it sheds light on these latter original contributions to the current knowledge, it questions the ability of the local bureaucracy to establish its own ‘polity’, the unsuitability of patronage political systems as an autonomous politological category, and the failure of Pakistan as a state. Individual chapters pursue questions of emotional belonging to spatial and political places, social change, everyday experiences of the state through its institutions, electoral politics, and the deployment of integration/accommodation practices as nation- and state-building processes
Accounting and the absence of a business economics tradition in the United Kingdom
No full textThe chapter explains why business economics did not emerge as a distinct discipline in the UK, and examines the extent to which accounting filled the gap left by this in UK universities
English-language theories of financial reporting
Full text linkThe chapter provides a historical overview of the principal theories of financial reporting in the English language. Early attempts to generalise from practice were supplemented with applications of economic theory, as well as ideas drawn from mathematics, systems theory, organisation theory, human behaviour and other disciplines to develop theories that attempted to improve current financial reporting practice. This has culminated in the development of conceptual frameworks for financial reporting. From the late 1960s, attempts have been developed to explain and predict accounting practice, and the impact of financial reporting information on the behaviour of investors and others
