Search for Low Mass Higgs at the Tevatron
We present CDF and D0 searches for a Standard Model Higgs boson produced
associatively with a W or Z boson at sqrt{s}=1.96 TeV using up to 1 fb^-1 of
analyzed Tevatron data collected from February 2002 to February 2006. For Higgs
masses less than 135 GeV/c^2, as is favored by experimental and theoretical
constraints, WH->lnubb, ZH->llbb, and ZH->nunubb are the most sensitive decay
channels to search for the Higgs boson. Both CDF and D0 have analyzed these
three channels and found no evidence for Higgs production, and therefore set
upper limits on the Higgs production cross-section. While the analyses are not
yet sensitive to Standard Model Higgs production, improvements in analysis
techniques are increasing sensitivity to the Higgs much faster than added
luminosity alone.Comment: ICHEP Moscow 2006 proceeding
The doctor and the blue form: learning professional responsibility
Book synopsis: This book presents leading-edge perspectives and methodologies to address emerging issues of concern for professional learning in contemporary society. The conditions for professional practice and learning are changing dramatically in the wake of globalization, new modes of knowledge production, new regulatory regimes, and increased economic-political pressures. In the wake of this, a number of challenges for learning emerge:
more practitioners become involved in interprofessional collaboration
developments in new technologies and virtual workworlds
emergence of transnational knowledge cultures and interrelated circuits of knowledge.
The space and time relations in which professional practice and learning are embedded are becoming more complex, as are the epistemic underpinnings of professional work. Together these shifts bring about intersections of professional knowledge and responsibilities that call for new conceptions of professional knowing.
Exploring what the authors call sociomaterial perspectives on professional learning they argue that theories that trace not just the social but also the material aspects of practice â such as tools, technologies, texts but also bodies and actions - are useful for coming to terms with the challenges described above.
Reconceptualising Professional Learning develops these issues through specific contemporary cases focused on one of the bookâs three main themes: (1) professionalsâ knowing in practice, (2) professionalsâ work arrangements and technologies, or (3) professional responsibility. Each chapter draws upon innovative theory to highlight the sociomaterial webs through which professional learning may be reconceptualised. Authors are based in Australia, Canada, Italy, Norway, Sweden, and the USA as well as the UK and their cases are based in a range of professional settings including medicine, teaching, nursing, engineering, social services, the creative industries, and more.
By presenting detailed accounts of these themes from a sociomaterial perspective, the book opens new questions and methodological approaches. These can help make more visible what is often invisible in todayâs messy dynamics of professional learning, and point to new ways of configuring educational support and policy for professionals
Responsibility matters: putting illness back into the picture
Purpose â The purpose of this paper is to explore specific instances of junior doctorsâ responsibility.
Learning is often understood to be a prerequisite for managing responsibility and risk but this paper
aims to argue that this is insufficient because learning is integral to the management of responsibility
and risk.
Design/methodology/approach â This is a âcollectiveâ case study of doctors designed to focus on the
interrelationships between individual professionals and complex work settings. The authors focussed on
two key points of transition: the transition to beginning clinical practice which is the move from medical
student to foundation training (F1) and the transition from generalist to specialist clinical practice.
Findings â Responsibility in clinical settings is immediate, concrete, demands response and (in)
action has an effect. Responsibility is learnt and is not always apparent; it shifts depending on time of
day/night and who else is present. Responsibility does not necessarily increase incrementally and can
decrease; it can be perceived differently by different actors. Responsibility is experienced as personal
although it is distributed.
Originality/value â This detailed examination of practice has enabled the authors to foreground the
particularities, urgency and fluidity of everyday clinical practice. It recasts their understandings of
responsibility â and managing risk â as involving learning in practice. This is a critical insight
because it suggests that the theoretical basis for the current approach to managing risk and
responsibility is insufficient. This has significant implications for policy, employment, education and
practice of new doctors and for the management of responsibility and risk
A report on nurses\u27 response to occupational injuries and exposures to hazards in a Californian community hospital
This study set out to determine the reasons for underreporting of occupational injuries and exposures in the American health care environment. A cross sectional survey was used to report the responses and opinions of nurses who failed to report all occupational injuries and exposures, and the type of injuries that are least likely to be reported. The participants were a random sample of Registered Nurses employed in a California Health Care Center, who responded to a simple self-reporting questionnaire. The study revealed that the majority of occupational injuries, accidents and exposures by this group in the previous twelve month period had gone unreported. Ineffective education, unfamiliarity with methods of reporting and poor staffing ratios were factors that led to poor compliance of reporting. Other factors such as length of service and experience did not influence reporting habits. The originality of this research was that the questionnaire looked at the compliance of health and safe practices with consideration of the personal beliefs and attitudes that nurses hold in the workplace. Its significance is that it identified and documented appropriate strategies for employers to use to rectify the problem of reporting occupational injuries and accidents as well as described and analyzed the current systems in place
High Energy Physics Opportunities Using Reactor Antineutrinos
Nuclear reactors are uniquely powerful, abundant, and flavor-pure sources of antineutrinos that continue to play a vital role in the US neutrino physics program. The US reactor antineutrino physics community is a diverse interest group encompassing many detection technologies and many particle physics topics, including Standard Model and short-baseline oscillations, BSM physics searches, and reactor flux and spectrum modeling. The community's aims offer strong complimentary with numerous aspects of the wider US neutrino program and have direct relevance to most of the topical sub-groups composing the Snowmass 2021 Neutrino Frontier. Reactor neutrino experiments also have a direct societal impact and have become a strong workforce and technology development pipeline for DOE National Laboratories and universities. This white paper, prepared as a submission to the Snowmass 2021 community organizing exercise, will survey the state of the reactor antineutrino physics field and summarize the ways in which current and future reactor antineutrino experiments can play a critical role in advancing the field of particle physics in the next decade
