Diagnostic Training in Clinical Mental Health Counseling Programs: Wrestling with the Identity Dialectic
The term Clinical Mental Health Counseling (CMHC) presents a dialectic (or unification of opposing truths) as the word “clinical” embodies diagnosis of illness in patients whereas professional counseling is rooted in developmental models of client issues, a humanistic stance and a wellness focus (Sweeney & Myers, 2005). Present day CMHC counselor educators have the task of creating a curriculum that facilitates students’ development of an identity that incorporates this dialectic. Ideally the CMHC graduate should be grounded in wellness and developmental models, understand the role of culture/environment in individual adaptation, adopt humanistic values and at the same time be prepared to diagnose and treat mental illness. Nearly 30 years ago West and colleagues (1988, p. 223) surveyed 150 mental health agencies regarding the role of counselors in these agencies and concluded that “counselor preparation should be strengthened in 4 areas: knowledge of psychotropic medication, psychopathology, individual assessment, and use of the Diagnostic and Statistical Manual of Mental Disorders.” The research examines CMHC programs and state licensing requirements in the light of this conclusion. The manner in which CACREP accredited CMHC programs deliver diagnostic and related clinical training in the 2-4 year Master’s degree plan is thoroughly explored. As these programs prepare students to work in jurisdictions supervised by licensing boards, this study also investigated licensing requirements for the 51 boards in the Continental US, Alaska and Hawaii. The following questions guided the research plan: 1. Do most programs offer a diagnostics (or psychopathology) course? 2. Where in the sequence is the diagnostics course situated? 3. Is the diagnostics course a prerequisite for fieldwork (practicum/internship)? 4. Do licensing requirements and credential titles reflect the identity dialectic
A Pilot Study Investigating the Effect of the Supervision-Questioning-Feedback Model of Supervision on Stimulating Critical Thinking in Speech-Language Pathology Graduate Students
Purpose
The purpose of this study was to investigate the effect of the supervision-questioning-feedback (SQF) model of supervision on critical thinking in graduate students studying speech-language pathology. The researchers hypothesized that students who were provided with the SQF model of supervision would score higher than students who received the non-SQF (NSQF) style of supervision on the selected critical thinking measures.
Method
Seventeen out of 24 first semester graduate students in speech-language pathology completing their on-site university-based clinical practicum experience consented to participate in the study. Of the 17 participating first semester students, 9 were randomly assigned to 1 of 3 SQF trained supervisors, and the other 8 were randomly assigned to 1 of 2 NSQF trained supervisors for the duration of 1 semester. Additionally, 3 out of 24 fourth semester graduate students completing their off-site externship experience and their supervisors consented to participate in the study. Four additional study participants served as independent SQF-trained raters charged with the task of analyzing video recorded student-supervisor conferences to determine whether the SQF model of supervision was being implemented. Prior to and at the conclusion of the clinical experience, all participating students completed two measures of critical thinking: (1) California Critical Thinking Skills Test (CCTST) and (2) two Simucase® clinical simulations. At the conclusion of the clinical experience, seventeen out of 20 participating students (11/12 SQF students and 6/8 NSQF students) completed a post-survey rating their supervisory experience
.
Results
For participating first semester students, there were no overall statistically significant differences between SQF and NSQF groups as measured by pre to post completion of (1) CCTST (p=.544) and (2) two Simucase® clinical simulations (p=.781). The 3 participating fourth semester students who received the SQF model of supervision also showed no statistically significant differences on pre to post completion of the (1) CCTST (p=.827) and (2) two Simucase® virtual cases (p=.879). Results from SQF ratings revealed variability in the implementation of the SQF model across supervisors with a moderate level of inter-rater agreement. Results from post surveys completed by students showed that students preferred the SQF model of supervision over the NSQF model (p=.044).
Conclusion
Results from this preliminary study indicated that the SQF model did not influence the overall outcomes on the selected critical thinking measures. Student preference for the SQF model may support existing evidence that learning clinicians want to be actively engaged in the supervisory process. There were several limitations to this study including the small sample size, variability in the implementation of the SQF model across supervisors, sensitivity of the selected critical thinking measures, and timing of post-intervention procedures. Further investigation of the effects of SQF on students’ critical thinking is warranted
Hidden local symmetry and color confinement
The hidden local symmetry is a successful model to describe the properties of
the vector mesons in QCD. We point out that if we identify this hidden gauge
theory as the magnetic picture of QCD, a linearized version of the model
simultaneously describes color confinement and chiral symmetry breaking. We
demonstrate that such a structure can be seen in the Seiberg dual picture of a
softly broken supersymmetric QCD. The model possesses exact chiral symmetry and
reduces to QCD when mass parameters are taken to be large. Working in the
regime of the small mass parameters, we show that there is a vacuum where
chiral symmetry is spontaneously broken and simultaneously the magnetic gauge
group is Higgsed. If the vacuum we find persists in the limit of large mass
parameters, one can identify the rho meson as the massive magnetic gauge boson,
that is an essential ingredient for color confinement.Comment: 20 pages, 3 figure
Multiple wurtzite twinning in CdTe nanocrystals induced by methylphosphonic acid.
Branching in semiconductor nanocrystals, which leads to tetrapods and to more complex architectures, is the subject of intensive investigation. Here we support the model according to which branching in CdTe nanocrystals is driven by the formation of multiple wurtzite twins. This is in contrast to previous models for this material. We found that twinning, as well as anisotropic growth, can be triggered by the presence of suitable molecules, such as for instance methylphosphonic acid. In the case of CdTe nanocrystals, we designed a robust growth scheme in which the variation of a single parameter (the concentration of methylphosphonic acid in solution) leads to the controlled formation of nanocrystals with shapes ranging from spheres to anisotropic structures with varying level of branching, as both twinning and anisotropic growth are progressively favored. We believe that these concepts can be extended to other nanocrystal systems
Nonabelian Faddeev-Niemi Decomposition of the SU(3) Yang-Mills Theory
Faddeev and Niemi (FN) have introduced an abelian gauge theory which
simulates dynamical abelianization in Yang-Mills theory (YM). It contains both
YM instantons and Wu-Yang monopoles and appears to be able to describe the
confining phase. Motivated by the meson degeneracy problem in dynamical
abelianization models, in this note we present a generalization of the FN
theory. We first generalize the Cho connection to dynamical symmetry breaking
pattern SU(N+1) -> U(N), and subsequently try to complete the Faddeev-Niemi
decomposition by keeping the missing degrees of freedom. While it is not
possible to write an on-shell complete FN decomposition, in the case of SU(3)
theory of physical interest we find an off-shell complete decomposition for
SU(3) -> U(2) which amounts to partial gauge fixing, generalizing naturally the
result found by Faddeev and Niemi for the abelian scenario SU(N+1) -> U(1)^N.
We discuss general topological aspects of these breakings, demonstrating for
example that the FN knot solitons never exist when the unbroken gauge symmetry
is nonabelian, and recovering the usual no-go theorems for colored dyons.Comment: Latex 30 page
RF plasma cleaning of optical surfaces: A study of cleaning rates on different carbon allotropes as a function of RF powers and distances
An extended study on an advanced method for the cleaning of carbon
contaminations on large optical surfaces using a remote inductively coupled low
pressure RF plasma source (GV10x downstream asher) is reported in this work.
Technical as well as scientific features of this scaled up cleaning process are
analyzed, such as the cleaning efficiency for different carbon allotropes
(amorphous and diamond-like carbon) as a function of feedstock gas composition,
RF power (ranging from 30 to 300W), and source-object distances (415 to 840
mm). The underlying physical phenomena for these functional dependences are
discussed.Comment: 16 pages, 9 figure
Circulating tumor DNA reflects uveal melanoma responses to protein kinase C inhibition
The prognosis for patients with UM is poor, and recent clinical trials have failed to prolong overall survival (OS) of these patients. Over 95% of UM harbor activating driver mutations, and this allows for the investigation of ctDNA. In this study, we investigated the value of ctDNA for adaptive clinical trial design in metastatic UM. Longitudinal plasma samples were analyzed for ctDNA in 17 metastatic UM patients treated with PKCi-based therapy in a phase 1 clinical trial setting. Plasma ctDNA was assessed using digital droplet PCR (ddPCR) and a custom melanoma gene panel for targeted next generation sequencing (NGS). Baseline ctDNA strongly correlated with baseline lactate dehydrogenase (LDH) (p \u3c 0.001) and baseline disease burden (p = 0.002). Early during treatment (EDT) ctDNA accurately predicted patients with clinical benefit to PKCi using receiver operator characteristic (ROC) curves (AUC 0.84, [95% confidence interval 0.65–1.0, p = 0.026]). Longitudinal ctDNA assessment was informative for establishing clinical benefit and detecting disease progression with 7/8 (88%) of patients showing a rise in ctDNA and targeted NGS of ctDNA revealed putative resistance mechanisms prior to radiological progression. The inclusion of longitudinal ctDNA monitoring in metastatic UM can advance adaptive clinical trial design
Acquisition and preliminary analysis of multi-channel seismic reflection data, acquired during the oceanographic cruises of the TOMO-ETNA experiment
The TOMO-ETNA experiment was performed in the framework of the FP7 “MED-SUV” (MEDiterranean SUpersite Volcanoes) in order to gain a detailed geological and structural model of the continental and oceanic crust concerning Etna and Aeolian Islands volcanoes (Sicily, Italy), by means of active and passive seismic exploration methodologies. Among all data collected, some 1410 km of marine multi-channel seismic (MCS) reflection profiles were acquired in the Ionian and Tyrrhenian Seas during two of the three oceanographic cruises of the TOMO-ETNA experiment, in July and November 2014, with the aim of shading light to deep, intermediate and shallow stratigraphy and crustal structure of the two above mentioned areas. The MCS sections, targeted to deep exploration, were acquired during the oceanographic cruise on board of the R/V “Sarmiento de Gamboa”, using an active seismic source of 16 air-guns, for a total volume of 4340 cu. in., and a 3000 m long, 240-channels digital streamer as receiving system. High-resolution seismic profiles were instead collected through the R/V “Aegaeo”, using two smaller air-guns (overall 270 cu. in. volume) and a 96 channels, 300 m long digital streamer. This paper provides a detailed description of the acquisition parameters and main processing steps adopted for the MCS data. Some processed lines are shown and preliminarily interpreted, to highlight the overall good quality and the high potential of the MCS sections collected during the TOMO-ETNA experiment. © 2016 by the Istituto Nazionale di Geofisica e Vulcanologia.

Matrix Models, Monopoles and Modified Moduli
Motivated by the Dijkgraaf-Vafa correspondence, we consider the matrix model
duals of N=1 supersymmetric SU(Nc) gauge theories with Nf flavors. We
demonstrate via the matrix model solutions a relation between vacua of theories
with different numbers of colors and flavors. This relation is due to an N=2
nonrenormalization theorem which is inherited by these N=1 theories.
Specializing to the case Nf=Nc, the simplest theory containing baryons, we
demonstrate that the explicit matrix model predictions for the locations on the
Coulomb branch at which monopoles condense are consistent with the quantum
modified constraints on the moduli in the theory. The matrix model solutions
include the case that baryons obtain vacuum expectation values. In specific
cases we check explicitly that these results are also consistent with the
factorization of corresponding Seiberg-Witten curves. Certain results are
easily understood in terms of M5-brane constructions of these gauge theories.Comment: 27 pages, LaTeX, 2 figure
