Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

Architecture in tension: an examination of the position of the architect in the private and public sectors, focusing on the training and careers of Sir Basil Spence (1907-1976) and Sir Donald Gibson (1908-1991)
No full textIn the early 1900s tensions began to appear within the architectural profession,
as private practitioners struggled to deal with the implications of professional
colleagues moving into public sector employment. Sir Basil Spence and Sir
Donald Gibson began their architectural training in the mid-1920s and, as
tensions between the sectors intensified, Spence entered private practice and
Gibson chose to enter the public sector. Each became an exemplar of his
chosen sector of the profession and yet both have, until recently, escaped
critical attention. The tensions between the public and private sectors of the
profession have been acknowledged within the historiography, but not received
detailed analysis.
This thesis advances the current historiography by presenting an examination
of the division between the sectors, focusing on the relationship between the
RIBA and the public sector union AASTA and assessing the influence of
AASTA on Gibson's Coventry City Architect's Department.
Through an examination of archival material, contemporary published material,
and buildings, this thesis builds on the work of the Sir Basil Spence Archive
Project, adding detailed accounts of his early life, architectural training, and
RIBA presidency, presenting new information and correcting certain aspects of
the accepted historiography. It likewise presents new information on Gibson's
early life and training and his central role in achieving improved status and
representation for the public sector. An analysis of selected projects provides a
comparative study of their contrasting approaches to architecture: the
technically informed, collaborative team-work of Gibson and the individual
artistry of Spence.
Both men played pivotal roles in reforming the RIBA and in changing public and
professional perceptions of the architect, nevertheless, the long lineage and
complex nature of tensions within the profession meant that the public/private
division was never be bridged and issues of status and representation
remained essentially immutable
Measurement of the cross-section ratio σ(χc2)/σ(χc1) for prompt χc production at √s=7 TeV
No full textThe prompt production of the charmonium χc1 and χc2 mesons has been studied in proton–proton collisions at the Large Hadron Collider at a centre-of-mass energy of . The χc mesons are identified through their decays χc→J/ψγ with J/ψ→μ+μ− using 36 pb−1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for the two χc spin states, σ(χc2)/σ(χc1), has been determined as a function of the J/ψ transverse momentum, , in the range from 2 to 15 GeV/c. The results are in agreement with the next-to-leading order non-relativistic QCD model at high and lie consistently above the pure leading-order colour-singlet prediction
Historical experiences, collective memory and willingness to fight for one’s country: Comments on Paez et al. (2008)
No full textThis paper considers Paez et al.’s (2008) article ‘“Remembering” World War II and willingness to fight: Sociocultural factors in the social representation of historical warfare across 22 societies.’ Despite the importance of their focus on social representations of history and willingness to fight for one’s country, it is argued that Paez et al.’s paper features a number of methodological flaws. Specifically, the way in which key variables (historical experience, collective memory and willingness to fight for one’s country) are operationalized is especially problematic. The implications of these weaknesses for their conceptual conclusions are discussed briefly, as are the more general limitations of statistical analyses of survey data for addressing these issues
Conducting a team-based multi-sited focused ethnography in primary care
No full textFocused ethnography is an applied and pragmatic form of ethnography that explores a specific social phenomenon as it occurs in everyday life. Based on the literature a problem-focused research question is formulated before the data collection. The data generation process targets key informants and situations so that relevant results on the pre-defined topic can be obtained within a relatively short time-span. As part of a theory based evaluation of alternative forms of consultation (such as video, phone and email) in primary care we used the focused ethnographic method in a multisite study in general practice across the UK. To date there is a gap in the literature on using focused ethnography in healthcare research.
The aim of the paper is to build on the various methodological approaches in health services research by presenting the challenges and benefits we encountered whilst conducing a focused ethnography in British primary care. Our considerations are clustered under three headings: constructing a shared understanding, dividing the tasks within the team, and the functioning of the focused ethnographers within the broader multi-disciplinary team.
As a result of using this approach we experienced several advantages, like the ability to collect focused data in several settings simultaneously within in a short time-span. Also, the sharing of experiences and interpretations between the researchers contributed to a more holistic understanding of the research topic. However, mechanisms need to be in place to facilitate and synthesise the observations, guide the analysis, and to ensure that all researchers feel engaged. Reflection, trust and flexibility among the team members were crucial to successfully adopt a team focused ethnographic approach. When used for policy focussed applied healthcare research a team-based multi-sited focused ethnography can uncover practices and understandings that would not be apparent through surveys or interviews alone. If conducted with care, it can provide timely findings within the fast moving context of healthcare policy and research
Receptionists’ role in new approaches to consultations in primary care : focused ethnographic study
No full textBackground
The receptionist is pivotal to the smooth running of general practice in the UK, communicating with patients and booking appointments.
Aim
The authors aimed to explore the role of the receptionist in the implementation of new approaches to consultations in primary care.
Design and setting
The authors conducted a team-based focused ethnography. Three researchers observed eight general practices across England and Scotland between June 2015 and May 2016.
Method
Interviews were conducted with 39 patients and 45 staff in the practices, all of which had adopted one or more methods (telephone, email, e-consultation, or internet video) for providing an alternative to face-to-face consultation.
Results
Receptionists have a key role in facilitating patient awareness regarding new approaches to consultations in primary care, while at the same time ensuring that patients receive a consultation appropriate to their needs. In this study, receptionists’ involvement in implementation and planning for the introduction of alternative approaches to face-to-face consultations was minimal, despite the expectation that they would be involved in delivery.
Conclusion
A shared understanding within practices of the potential difficulties and extra work that might ensue for reception staff was lacking. This might contribute to the low uptake by patients of potentially important innovations in service delivery. Involvement of the wider practice team in planning and piloting changes, supporting team members through service reconfiguration, and providing an opportunity to discuss and contribute to modifications of any new system would ensure that reception staff are suitably prepared to support the introduction of a new approach to consultations
Alternatives to the face-to-face consultation in general practice : focused ethnographic case study
No full textBackground NHS policy encourages general practices to introduce alternatives to the face-to-face consultation, such as telephone, email, e-consultation systems, or internet video. Most have been slow to adopt these, citing concerns about workload. This project builds on previous research by focusing on the experiences of patients and practitioners who have used one or more of these alternatives.
Aim To understand how, under what conditions, for which patients, and in what ways, alternatives to face-to-face consultations present benefits and challenges to patients and practitioners in general practice.
Design and setting Focused ethnographic case studies took place in eight UK general practices between June 2015 and March 2016.
Method Non-participant observation, informal conversations with staff, and semi-structured interviews with staff and patients were conducted. Practice documents and protocols were reviewed. Data were analysed through charting and the ‘one sheet of paper’ mind-map method to identify the line of argument in each thematic report.
Results Case study practices had different rationales for offering alternatives to the face-to-face consultation. Beliefs varied about which patients and health issues were suitable. Co-workers were often unaware of each other’s practice; for example, practice policies for use of e-consultations systems with patients were not known about or followed. Patients reported benefits including convenience and access. Staff and some patients regarded the face-to-face consultation as the ideal.
Conclusion Experience of implementing alternatives to the face-to-face consultation suggests that changes in patient access and staff workload may be both modest and gradual. Practices planning to implement them should consider carefully their reasons for doing so and involve the whole practice team
