"Taking your place at the table": an autoethnographic study of chaplains' participation on an interdisciplinary research team.
BackgroundThere are many potential benefits to chaplaincy in transforming into a "research-informed" profession. However little is known or has been documented about the roles of chaplains on research teams and as researchers or about the effects of research engagement on chaplains themselves. This report describes the experience and impact of three chaplains, as well as tensions and challenges that arose, on one particular interdisciplinary team researching a spiritual assessment model in palliative care. Transcripts of our research team meetings, which included the three active chaplain researchers, as well as reflections of all the members of the research team provide the data for this descriptive, qualitative, autoethnographic analysis.MethodsThis autoethnographic project evolved from the parent study, entitled "Spiritual Assessment Intervention Model (AIM) in Outpatient Palliative Care Patients with Advanced Cancer." This project focused on the use of a well-developed model of spiritual care, the Spiritual Assessment and Intervention Model (Spiritual AIM). Transcripts of nine weekly team meetings for the parent study were reviewed. These parent study team meetings were attended by various disciplines and included open dialogue and intensive questions from non-chaplain team members to chaplains about their practices and Spiritual AIM. Individual notes (from reflexive memoing) and other reflections of team members were also reviewed for this report. The primary methodological framework for this paper, autoethnography, was not only used to describe the work of chaplains as researchers, but also to reflect on the process of researcher identity formation and offer personal insights regarding the challenges accompanying this process.ResultsThree major themes emerged from the autoethnographic analytic process: 1) chaplains' unique contributions to the research team; 2) the interplay between the chaplains' active research role and their work identities; and 3) tensions and challenges in being part of an interdisciplinary research team.ConclusionsDescribing the contributions and challenges of one interdisciplinary research team that included chaplains may help inform chaplains about the experience of participating in research. As an autoethnographic study, this work is not meant to offer generalizable results about all chaplains' experiences on research teams. Research teams that are interdisciplinary may mirror the richness and efficacy of clinical interdisciplinary teams. Further work is needed to better characterize both the promise and pitfalls of chaplains' participation on research teams
A Multivariate Training Technique with Event Reweighting
An event reweighting technique incorporated in multivariate training
algorithm has been developed and tested using the Artificial Neural Networks
(ANN) and Boosted Decision Trees (BDT). The event reweighting training are
compared to that of the conventional equal event weighting based on the ANN and
the BDT performance. The comparison is performed in the context of the physics
analysis of the ATLAS experiment at the Large Hadron Collider (LHC), which will
explore the fundamental nature of matter and the basic forces that shape our
universe. We demonstrate that the event reweighting technique provides an
unbiased method of multivariate training for event pattern recognition.Comment: 20 pages, 8 figure
A Submillimeter HCN Laser in IRC+10216
We report the detection of a strong submillimeter wavelength HCN laser line
at a frequency near 805 GHz toward the carbon star IRC+10216. This line, the
J=9-8 rotational transition within the (04(0)0) vibrationally excited state, is
one of a series of HCN laser lines that were first detected in the laboratory
in the early days of laser spectroscopy. Since its lower energy level is 4200 K
above the ground state, the laser emission must arise from the inner part of
IRC+10216's circumstellar envelope. To better characterize this environment, we
observed other, thermally emitting, vibrationally excited HCN lines and find
that they, like the laser line, arise in a region of temperature approximately
1000 K that is located within the dust formation radius; this conclusion is
supported by the linewidth of the laser. The (04(0)0), J=9-8 laser might be
chemically pumped and may be the only known laser (or maser) that is excited
both in the laboratory and in space by a similar mechanism.Comment: 11 pages, 3 figure
Getting beta-alpha without penguins
Oscillation effects in B0 -> Ks D0 and related processes are considered to
determine delta=beta-alpha+pi. We suggest that D0 decays to CP eigenstates used
in concert with inclusive D0 decays provide a powerful method for determining
delta cleanly i.e. without any complication from penguin processes. The CP
asymmetry is expected to be <=40% for D0 decays to non-CP eigenstates and <=80%
for decays to CP eigenstates. This method can lead to a fairly accurate
determination of delta with O(10^8-10^9) B-mesons.Comment: 4 pages 1 figure; Version 2: minor changes; references added; Some

CP Violation in a Supersymmetric SO(10) x U(2)_{F} Model
A model based on SUSY SO(10) combined with U(2) family symmetry constructed
recently by the authors is generalized to include phases in the mass matrices
leading to CP violation. In contrast with the commonly used effective operator
approach, -dimensional Higgs fields are utilized to construct the
Yukawa sector. R-parity symmetry is thus preserved at low energies. The
symmetric mass textures arising from the left-right symmetry breaking chain of
SO(10) give rise to very good predictions for quark and lepton masses and
mixings. The prediction for agrees with the average of current
bounds from BaBar and Belle. In the neutrino sector, our predictions are in
good agreement with results from atmospheric neutrino experiments. Our model
favors both the LOW and QVO solutions to the solar neutrino anomaly; the matrix
element for neutrinoless double beta decay is highly suppressed. The leptonic
analog of the Jarlskog invariant, , is predicted to be of

Ubiquitous CP violation in a top-inspired left-right model
We explore CP violation in a Left-Right Model that reproduces the quark mass
and CKM rotation angle hierarchies in a relatively natural way by fixing the
bidoublet Higgs VEVs to be in the ratio m_b:m_t. Our model is quite general and
allows for CP to be broken by both the Higgs VEVs and the Yukawa couplings.
Despite this generality, CP violation may be parameterized in terms of two
basic phases. A very interesting feature of the model is that the mixing angles
in the right-handed sector are found to be equal to their left-handed
counterparts to a very good approximation. Furthermore, the right-handed
analogue of the usual CKM phase delta_L is found to satisfy the relation
delta_R \approx delta_L. The parameter space of the model is explored by using
an adaptive Monte Carlo algorithm and the allowed regions in parameter space
are determined by enforcing experimental constraints from the K and B systems.
This method of solution allows us to evaluate the left- and right-handed CKM
matrices numerically for various combinations of the two fundamental CP-odd
phases in the model. We find that all experimental constraints may be satisfied
with right-handed W and Flavour Changing Neutral Higgs masses as low as about 2
TeV and 7 TeV, respectively.Comment: 37 pages, 13 figure
Measuring V_ub and probing SUSY with double ratios of purely leptonic decays of B and D mesons
The experimental prospects for precise measurements of the leptonic decays
B_u -> tau nu / mu nu, B_s -> mu+ mu-, D -> mu nu and D_s -> mu nu / tau nu are
very promising. Double ratios involving four of these decays can be defined in
which the dependence on the values of the decay constants is essentially
eliminated, thus enabling complementary measurements of the CKM matrix element
V_ub with a small theoretical error. We quantify the experimental error in a
possible future measurement of |V_ub| using this approach, and show that it is
competitive with the anticipated precision from the conventional approaches.
Moreover, it is shown that such double ratios can be more effective than the
individual leptonic decays as a probe of the parameter space of supersymmetric
models. We emphasize that the double ratios have the advantage of using |V_ub|
as an input parameter (for which there is experimental information), while the
individual decays have an uncertainty from the decay constants (e.g. f_B_s),
and hence a reliance on theoretical techniques such as lattice QCD.Comment: 21 pages, 4 figure
