β-delayed proton emission from nuclei near doubly magic ¹⁰⁰Sn
No full textThe proton-rich region of the nuclear chart surrounding the doubly magic nucleus
¹⁰⁰Sn (N = Z = 50) is of great interest in nuclear structure studies, in particular
when examining the limits of proton stability and the location of the proton drip-
line. Measurement of the properties of unstable nuclei in this region serves as a
direct test of the shell model for exotic isotopes further from stability. To this end,
an experiment was carried out at the Radioactive Ion Beam Factory (RIBF) at
RIKEN, Japan. Isotopes in this region were produced following fragmentation of
a primary ¹²⁴Xe beam (E beam = 345 MeV/u, beam intensity of 120 pnA) impinged
on a 9 Be target, to then be separated and identified, and finally guided along the
beamline and implanted in the Advanced Implantation Detector Array (AIDA).
AIDA is a state-of-the-art silicon detector array which was used in coincidence
with the Decay Total Absorption γ-ray Spectrometer (DTAS), a NaI crystal array
γ detection system, to measure the decay properties of exotic, short-lived unstable
proton-rich nuclei near ¹⁰⁰Sn.
This thesis presents an analysis of data collected with AIDA during this
experiment, notably for the first time with proton-rich nuclei. Measurements
of the β-delayed proton decay half-lives, branching ratios and energy spectra of
20 nuclei in the region of ¹⁰⁰Sn are presented in this work, the latter of which
was measured with significantly increased energy resolution compared to previous
studies.
β-delayed proton emission from ¹⁰¹Sn was analysed in depth, and compared to
predictions from shell model calculations in the context of identifying the ground-
state spin of this nucleus.
The data collected in this experiment also provided an opportunity to characterise
the fast-recovery time of AIDA, in the context of identifying very short-lived decay
events with half-lives ∼ μs. This characterisation was applied to constrain the
half-life of potential proton emission from an isomer in ⁹⁷In, which has not been
directly detected in this work or in previous studies

Am I doing the right thing? Plunket nurses' experience in making decisions to report suspected child abuse and neglect
No full textSuspected child abuse and neglect is not a new phenomenon in community nursing. Child abuse and/or neglect is prevalent globally and is a major community concern. Plunket Nurses have a primary responsibility to protect the health and well being of the women and children with whom they come into contact. Detecting suspected child abuse and/or neglect and making decisions to report to Child, Youth and Family, New Zealand’s Statutory Agency, is difficult. There are professional, legal, ethical and moral complexities in this work. Boyne (2003) states that there has not been enough research about what it is like to work with and manage risks in child protection work. This study set out to report these experiences in view of understanding them and finding possible gaps in literature, policy, and education.
Hermeneutic phenomenology was the methodology thought most appropriate to study the experiences of Plunket Nurses making decisions to report suspected child abuse and/or neglect in uncertain situations. A purposeful sample was selected to ensure participants were able to provide rich data that was captured in semi-structured, face to face and telephone recorded interviews. Data analysis was guided by the framework developed by van Manen (1990) to formulate meaning from participant experiences. Four major themes developed.
Ethical considerations were extensively explored due to the sensitive nature of the study. Management of possible ethical situation have been described, with a planned approach to an ongoing consent process throughout the data collection. The results have identified gaps in the literature, Plunket policy and the educational needs of Plunket Nurses. Opportunities for future research are suggested
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

No full textPhotographs of "From the Front" trench poetry edited by C.E. Andrews, held by UNT Special Collections. It is bound in an uniform green cloth binding, and the front cover bears the title “From the Front,” the full name of the editor in all caps, and a logo of two swords crossed, a hat in the middle, and olive leaves wreath circling the swords, all of which was stamped with gold metallic color.. Image 2, page 198 and 199. The page on the right is titled "Good-By." Image 3, page 200 and 201. Image 4, page 202 and 203. The page on the right is titled "Matey." During World War I, a genre of poetry emerged from the front lines termed “Trench Poetry.” It was inspired by the soldiers’ daily life on the front, especially the constant witnessing and interacting with horrifying scenes. The editor of this book, Lieutenant C. E. Andrews, served in the Aviation Section, Signal Reserve Corps during World War I. Surprisingly, during the course of his examination of “thousands of the poems from the front [that] have appeared in newspapers and magazines,” Andrews learned that most trench poetry was not written by soldiers, but by “men of cultivation, Doctor, dons, actors, journalists university students” since the soldiers in the front lines had no time to absorb their experience in order to reflect it in a condensed rhetorical form. In his introduction on “trench poetry,” Andrews argues that the most canonical poetry is not written by “forgers of experience” but by “men with sense of the word.” As a result, the reactions of soldiers normally appeared either through letters to their families and loved ones or through familiar, short lyrics. This is what Andrews selects for his collection From the Front. The book was published by D. Appleton & Co, London 1918 and all its royalties went to the British Red Cross fund. The book includes an index of authors and of first lines in the back, which allows the reader to navigate the collection and find poems by specific authors
Multiple higgs and vector boson production beyond the standard model
No full textIf the electroweak symmetry breaking is originated from a strongly coupled sector, as for instance in composite Higgs models, the Higgs boson couplings can deviate from their Standard Model values. In such cases, at sufficiently high energies there could occur an onset of multiple Higgs boson and longitudinally polarised electroweak gauge boson (V L ) production. We study the sensitivity to anomalous Higgs couplings in inelastic processes with 3 and 4 particles (either Higgs bosons or V L 's) in the final state. We show that, due to the more severe cancellations in the corresponding amplitudes as compared to the usual 2 → 2 processes, large enhancements with respect to the Standard Model can arise even for small modifications of the Higgs couplings. In particular, we find that triple Higgs production provides the best multiparticle channel to look for these deviations. We briefly explore the consequences of multiparticle production at the LHC. © 2013 SISSA.School of Physics and Astronomy University of Southampton Highfield, Southampton SO17 1BJParticle Physics Department Rutherford Appleton Laboratory Chilton, Didcot Oxon OX11 0QXInstituto de Física Teórica Universidade Estadual Paulista ICTP South American Institute for Fundamental Research, Rua Dr. Bento T.

A case study investigation into the diffusion of e-mediated learning technology in UK higher education
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 20/01/2006.This thesis addresses the following research paradox: Despite continual investment in e-mediated learning technology by higher education institutions, why has technological diffusion within UK universities been a slow process? It will be argued that the level of investment in e-mediated learning technology by UK universities and the impact of this technology across higher education as a whole, makes this subject area an appropriate setting in which to study this phenomenon. An interpretivist case study investigation of the adaptation process of e-mediated learning technology by academic staff is analysed through the development of a grounded theory approach. The investigation will show that the majority of academic staff in the School of Management at the Case Study University are adopting e-mediated learning technology at a basic level. Various factors can combine to influence technological adoption. These include conflicting priorities for academic staff, IT skills levels and the potential for the technology to transform the social relation between the academic member of staff and student leading towards a heightened culture of expectation. In addition, the study will show that e-mediated learning technology has the ability to place the expertise of the academic member of staff in a vulnerable position. Together these factors can combine to affect the successful diffusion of e-mediated learning technologies in UK universities. At a more critical level, the research identifies that using models of critical mass in isolation to indicate the take-up of multi-functional e-mediated learning technologies are misleading. As such, models that incorporate the levels and stages, as well as the pace of adoption provide a more detailed perspective of the successful diffusion of e-mediated learning technology
ON FINANCIAL ACCOUNTING MEASUREMENT: A RECONSIDERATION OF SFAC 5 BY THE FASB IS NEEDED
No full textThis paper attempts to reinforce by means of social theory the procedure and property (attribute) of financial accounting measurement advanced by Salvary [1985,1989,1992]. The procedure entails estimating the amount of cash flows derivable from existing investment projects; and the measurement property (attribute) is identified as recoverable cost. The 'cash-in and cash-out' principle establishes financial capital maintenance as the appropriate capital maintenance concept to be followed in the measurement of periodic income. An analogy between a bank savings account and an equity security is used to identify the measurement property (attribute) and validate the additivity of financial accounting numbers. Problems with the monetarist model were used to demonstrate the appropriateness (stability) of the measurement scale (monetary unit). The logical analysis developed in this paper makes a compelling case for a reconsideration of Statement of Financial Accounting Concept No. 5 by the FASB.capital maintenance; 'cash-in and cash-out' principle; organizing of economic activities; cost efficient means of transacting; uncertain purchasing power; price mechanism; intertemporal transfer of risks; Replacement of non-monetary assets; a venture approach; intersavers' transfer of risks; storage of financial capital;savings account; effectiveness and efficiency in cash management; Hicksian consumption model.
