Becoming Psychotherapists: Experiences of Novice Trainees in a Beginning Graduate Class
The authors investigated the experiences related to becoming psychotherapists for 5 counseling psychology doctoral trainees in their first prepracticum course. Qualitative analyses of weekly journals indicated that trainees discussed challenges related to becoming psychotherapists (e.g., being self-critical, having troubling reactions to clients, learning to use helping skills), gains made during the semester related to becoming psychotherapists (e.g., using helping skills more effectively, becoming less self-critical, being able to connect with clients), as well as experiences in supervision and activities that helped them cope with their anxieties. Results are discussed in 5 broad areas: feelings about self in role of psychotherapist, awareness of reactions to clients, learning and using helping skills, reactions to supervision, and experiences that fostered growth. Implications for training and research are provided
A Qualitative Examination of Graduate Advising Relationships: The Advisor Perspective
Nineteen counseling psychology faculty members were interviewed regarding their advising relationships with doctoral students. Advisors informally learned to advise from their experiences with their advisor and their advisees and defined their role as supporting and advocating for advisees as they navigated their doctoral program. Advisors identified personal satisfaction as a benefit and time demands as a cost of advising. Good advising relationships were facilitated by adviseesâ positive personal or professional characteristics, mutual respect, open communication, similarity in career path between advisor and advisee, and lack of conflict. Difficult relationships were affected by adviseesâ negative personal or professional characteristics, lack of respect, research struggles, communication problems, advisors feeling ineffective working with advisees, disruption or rupture of the relationship, and conflict avoidance. Implications for research and training are discussed
Gas Gain Measurements from a Negative Ion TPC X-ray Polarimeter
Gas-based time projection chambers (TPCs) have been shown to be highly
sensitive X-ray polarimeters having excellent quantum efficiency while at the
same time achieving large modulation factors. To observe polarization of the
prompt X-ray emission of a Gamma-ray burst (GRB), a large area detector is
needed. Diffusion of the electron cloud in a standard TPC could be prohibitive
to measuring good modulation when the drift distance is large. Therefore, we
propose using a negative ion TPC (NITPC) with Nitromethane (CH3NO2) as the
electron capture agent. The diffusion of negative ions is reduced over that of
electrons due to the thermal coupling of the negative ions to the surrounding
gas. This allows for larger area detectors as the drift distance can be
increased without degrading polarimeter modulation. Negative ions also travel
~200 times slower than electrons, allowing the readout electronics to operate
slower, resulting in a reduction of instrument power. To optimize the NITPC
design, we have measured gas gain with SciEnergy gas electron multipliers
(GEMs) in single and double GEM configurations. Each setup was tested with
different gas combinations, concentrations and pressures: P10 700 Torr, Ne+CO2
700 Torr at varying concentrations of CO2 and Ne+CO2+CH3NO2 700 Torr. We report
gain as a function of total voltage, measured from top to bottom of the GEM
stack, and as a function of drift field strength for the gas concentrations
listed above. Examples of photoelectron tracks at 5.9 keV are also presented.Comment: 6 pages, 6 figures, accepted for publication in IEEE Trans Nucl Sc
A Qualitative Examination of Graduate Advising Relationships:The Advisee Perspective
Sixteen 3rd-year counseling psychology doctoral students were interviewed about their relationships with their graduate advisors. Of those students, 10 were satisfied and 6 were unsatisfied with their advising relationships. Satisfied and unsatisfied students differed on several aspects of the advising relationship, including (a) the ability to choose their advisors, (b) the frequency of meetings with their advisors, (c) the benefits and costs associated with their advising relationships, and (d) how conflict was dealt with in the advising relationship. Furthermore, all of the satisfied students reported that their advising relationships became more positive over time, whereas many of the unsatisfied students reported that their advising relationships got worse (e.g., became more distant) over time

The Axiverse Extended: Vacuum Destabilisation, Early Dark Energy and Cosmological Collapse
A model is presented in the philosophy of the "String Axiverse" of Arvanitaki
et al (arXiv:0905.4720v2 [hep-th]) that incorporates a coupling of ultralight
axions to their corresponding moduli through the mass term. The light fields
roll in their potentials at late times and contribute to the dark sector energy
densities in the cosmological expansion. The addition of a coupling and extra
field greatly enrich the possible phenomenology of the axiverse. There are a
number of interesting phases where the axion and modulus components behave as
Dark Matter or Dark Energy and can have considerable and distinct effects on
the expansion history of the universe by modifying the equation of state in the
past or causing possible future collapse of the universe. In future such a
coupling may help to alleviate fine tuning problems for cosmological axions. We
motivate and present the model, and briefly explore its cosmological
consequences numerically.Comment: 13 pages, 17 figures, published in PRD. v3: corrected SUSY

Women's perceptions and self-reports of excessive bleeding during and after delivery: findings from a mixed-methods study in Northern Nigeria
OBJECTIVES: To explore lay perceptions of bleeding during and after delivery, and measure the frequency of self-reported indicators of bleeding. SETTING: Yola, North-East Nigeria. PARTICIPANTS: Women aged 15-49 years who delivered in the preceding 2 years of data collection period (2015-2016), and their family members who played key roles. METHODS: Data on perceptions of bleeding were collected through 7 focus group discussions, 21 in-depth interviews and 10 family interviews. Sampling was purposive and data were analysed thematically. A household survey was then conducted with 640 women using cluster sampling on postpartum bleeding indicators developed from the qualitative data; data were analysed descriptively. RESULTS: Perceptions of excessive bleeding fell under four themes: quantity of blood lost; rate/duration of blood flow; symptoms related to blood loss and receiving birth interventions/hearing comments from birth attendants. Young and less educated rural women had difficulty quantifying blood loss objectively, including when shown quantities using bottles. Respondents felt that acceptable blood loss levels depended on the individual woman and whether the blood is 'good' or 'diseased/bad.' Respondents believed that 'diseased' blood was a normal result of delivery and universally took steps to help it 'come out.' In the quantitative survey, indicators representing less blood loss were reported more frequently than those representing greater loss, for example, more women reported staining their clothes (33.6%) than the bed (18.1%) and the floor (6.2%). Overall, indicators related to quantity and rate of blood flow had higher frequencies compared with symptom and intervention-related/comment-related indicators. CONCLUSION: Women quantify bleeding during and after delivery in varied ways and some women do not see bleeding as problematic. This suggests the need for standard messaging to address subjectivity. The range of indicators and varied frequencies highlight the challenges of measuring excessive bleeding from self-reports. More work is needed in improving and testing validity of questions
On resonant scatterers as a factor limiting carrier mobility in graphene
We show that graphene deposited on a substrate has a non-negligible density
of atomic scale defects. This is evidenced by a previously unnoticed D peak in
the Raman spectra with intensity of about 1% with respect to the G peak. We
evaluated the effect of such impurities on electron transport by mimicking them
with hydrogen adsorbates and measuring the induced changes in both mobility and
Raman intensity. If the intervalley scatterers responsible for the D peak are
monovalent, their concentration is sufficient to account for the limited
mobilities achievable in graphene on a substrate.Comment: version 2: several comments are taken into account and refs adde
Yukawa Deflected Gauge Mediation in Four Dimensions
We construct a four dimensional realization of a higher dimensional model,
Yukawa deflected gauge mediation, in which supersymmetry breaking is
communicated to the visible sector through both gauge and Yukawa interactions.
The reduction to four dimensions is achieved by `deconstructing' or
`latticizing' the extra dimension. Three sites (gauge groups) are sufficient to
reproduce the spectrum of the higher dimensional model. The characteristic
features of Yukawa deflected gauge mediation, in particular, alignment of
squarks and quarks, and a natural solution to the mu problem, carry over to the
deconstructed version of the model. We comment on the implications of our
results for a solution of the mu problem in the context of deconstructed
gaugino mediation.Comment: 11 pages, 1figur
Unpaired Electrons in the Heavy-Fermion Superconductor CeCoIn_{5}
Thermal conductivity and specific heat were measured in the superconducting
state of the heavy fermion material Ce_{1-x}La_{x}CoIn_{5}. With increasing
impurity concentration x, the suppression of T_{c} is accompanied by the
increase in the residual electronic specific heat expected of a d-wave
superconductor, but it occurs in parallel with a decrease in residual
electronic thermal conductivity. This contrasting behavior reveals the presence
of uncondensed electrons coexisting with nodal quasiparticles. An extreme
multiband scenario is proposed, with a d-wave superconducting gap on the
heavy-electron sheets of the Fermi surface and a negligible gap on the light,
three-dimensional pockets.Comment: 4 pages, 3 figure
