Seeking Treatment for PTSD: the Post 9/11 Service Member\u27s Experience
Posttraumatic-stress disorder (PTSD) remains one of the most pervasive health conditions to affect the 2.7 million United States service members deployed to Iraq and Afghanistan since 2001. Untreated and/or inadequately treated PTSD can further lead to an array of health risks including anxiety, depression, substance abuse, social and occupational impairments, poorer quality of physical health, decreased overall perception of quality of life, and increase the risk of suicide. Considering these risks, the Department of Veterans Affairs (VA) and Department of Defense (DoD) created the VA/DOD Clinical Practice Guidelines (CPGs) for the Management of PTSD and Acute Stress Reaction (ASR), highlighting the strongest evidence-based approaches to treatment for clinicians providing care for service members. The CPGs further outlines the importance of providing clients/patients with psychoeducation regarding PTSD and treatment options, offering a client-centered approach through a Shared Decision-Making Model (SDM), while also illustrating known barriers to treatment, and concerns regarding early termination. Successful implementation of the CPGs is expected to enhance assessment of clientâs/patientâs needs and assist in determining and providing effective care. The number of veterans suffering with PTSD continues to be an alarming concern, one with life-threatening implications. While this concern is recognized among clinicians, statistics continue to highlight the vast number of those suffering with PTSD and PTSD related conditions, further pressing the need to explore additional ways to improve the efficacy of treatment. The purpose of this study is to explore the post 9/11 military populationâs experience in seeking treatment, as reflected by the CPGs recommendations, while further exploring their views regarding ways to improve the efficacy of assessing and treating PTSD.

Some recent results on niche graphs
AbstractIn an earlier paper entitled âNiche graphsâ written by Cable, Jones, Lundgren and Seager, niche graphs were introduced and examples were provided of graphs which have niche number 0, 1, 2, and â. However, no examples were found of a niche graph having finite niche number 3 or larger. We still have had no success in our efforts to find such a graph. Nevertheless we have gotten some interesting results. For example, we show in this paper that if there is such a graph, then there must be one which is connected. We also show that the niche number of a graph which has a finite niche number is â€23|V(G)|. In addition we determine the niche number of all âwheelâ graphs
Concept of Formation Length in Radiation Theory
The features of electromagnetic processes are considered which connected with
finite size of space region in which final particles (photon, electron-positron
pair) are formed. The longitudinal dimension of the region is known as the
formation length. If some external agent is acting on an electron while
traveling this distance the emission process can be disrupted. There are
different agents: multiple scattering of projectile, polarization of a medium,
action of external fields, etc. The theory of radiation under influence of the
multiple scattering, the Landau-Pomeranchuk-Migdal (LPM) effect, is presented.
The probability of radiation is calculated with an accuracy up to "next to
leading logarithm" and with the Coulomb corrections taken into account. The
integral characteristics of bremsstrahlung are given, it is shown that the
effective radiation length increases due to the LPM effect at high energy. The
LPM effect for pair creation is also presented. The multiple scattering
influences also on radiative corrections in a medium (and an external field
too) including the anomalous magnetic moment of an electron and the
polarization tensor as well as coherent scattering of a photon in a Coulomb
field. The polarization of a medium alters the radiation probability in soft
part of spectrum. Specific features of radiation from a target of finite
thickness include: the boundary photon emission, interference effects for thin
target, multi-photon radiation. The experimental study of LPM effect is
described. For electron-positron colliding beams following items are discussed:
the separation of coherent and incoherent mechanisms of radiation, the
beam-size effect in bremsstrahlung, coherent radiation and mechanisms of
electron-positron creation.Comment: Revised review paper, 96 pages, 28 figures. Description of SLAC E-146

Testing Higgs models via the vertex by a recoil method at the International Linear Collider
In general, charged Higgs bosons appear in non-minimal Higgs models.
The vertex is known to be related to the violation of the
global symmetry (custodial symmetry) in the Higgs sector. Its magnitude
strongly depends on the structure of the exotic Higgs models which contain
higher isospin representations such as triplet Higgs bosons. We study
the possibility of measuring the vertex via single charged
Higgs boson production associated with the boson at the International
Linear Collider (ILC) by using the recoil method. The feasibility of the signal
is analyzed assuming the polarized
electron and positron beams and the expected detector performance for the
resolution of the two-jet system at the ILC. The background events can be
reduced to a considerable extent by imposing the kinematic cuts even if we take
into account the initial state radiation. For a relatively light charged Higgs
boson whose mass is in the region of 120-130 GeV , the vertex would be precisely testable especially
when the decay of is lepton specific. The exoticness of the extended
Higgs sector can be explored by using combined information for this vertex and
the rho parameter.Comment: 22 pages, 23 figure
b --> s g g decay in the two and three Higgs doublet models with CP violating effects
We study the decay width and CP-asymmetry of the inclusive process b--> s g g
(g denotes gluon) in the three and two Higgs doublet models with complex Yukawa
couplings. We analyse the dependencies of the differential decay width and
CP-asymmetry to the s- quark energy E_s and CP violating parameter \theta. We
observe that there exist a considerable enhancement in the decay width and CP
asymmetry is at the order of 10^{-2}. Further, it is possible to predict the
sign of C_7^{eff} using the CP asymmetry.Comment: 15 pages, 7 Figures (required epsf style
Genome Dynamics Are Influenced by Food Source in Allogromia laticollaris Strain CSH (Foraminifera)
Across the eukaryotic tree of life, genomes vary within populations and within individuals during their life cycle. Understanding intraspecific genome variation in diverse eukaryotes is key to elucidating the factors that underlie this variation. Here, we characterize genome dynamics during the life cycle of Allogromia laticollaris strain CSH, a member of the Foraminifera, using fluorescence microscopy and reveal extensive variation in nuclear size and DNA content. Both nuclear size and DNA content are tightly correlated across a 700-fold range in cell volume. In contrast to models in yeast where nuclear size is determined solely by cell size, the relationship in A. laticollaris CSH differs according to both life cycle stage and food source. Feeding A. laticollaris CSH a diet that includes algae results in a 2-fold increase in DNA content in reproductive cells compared with a diet of bacteria alone. This difference in DNA content likely corresponds to increased fecundity, as reproduction occurs through segregation of the polyploid nucleus into numerous daughter nuclei. Environmentally mediated variation in DNA content may be a widespread phenomenon, as it has been previously reported in the plant flax and the flagellate Euglena. We hypothesize that DNA content is influenced by food in other single-celled eukaryotes with ploidy cycles and that this genome flexibility may enable these eukaryotes to maximize fitness across changing environmental conditions
Digitization in Small Cultural Heritage Repositories: Interviews with NC ECHO EZ Digitization Starter Grant Recipients
There is scant literature available that specifically addresses digitization efforts in small cultural heritage institutions. However, even without this specific guidance these institutions are creating digital projects whether by grassroots efforts, collaborations with other institutions, or through participation in regional or statewide digital initiatives. Due to the many factors involved with digitization, (costs, technology, staff time, access, and preservation issues) small cultural heritage institutions encounter many issues and challenges. This study was devised to discover the common practices and obstacles encountered by NC ECHO Digitization Starter Grant award recipients' cultural heritage institutions during digitization, in the hopes of improving digitization guidelines by making them more responsive to the current practice of digitization as experienced by these institutions
