Gender Diversity Cultural Responsiveness Education in Speech-Language Pathology Graduate Programs: A Pilot Survey
Purpose: Gender-affirming voice therapy aims to align a personâs voice and communication with their gender identity. Historically, transgender and gender-nonconforming (TGNC) individuals have been marginalized and continue to face significant healthcare disparities. The goal of this research was to examine the self-perceived preparedness of recent speech-language pathology (SLP) graduates for working with TGNC clients. A survey was developed to include both multiple choice and open-ended questions. Topics included graduate-level training on working with TGNC individuals, perceived preparedness to work with this client population, educational resources sought by respondents, and suggested improvements for SLP graduate programs. Thirty recent (since 2016) SLP graduates completed the survey anonymously. Although a majority (83%) of respondents reported that working with TGNC clients was addressed in their graduate education, 66% of respondents felt that instruction time spent on this topic was insufficient or slightly insufficient. Those who had clinical experiences with TGNC clients, or who learned from the perspectives of the TGNC community (e.g., from a guest speaker or video), reported that their graduate education better prepared them to work with TGNC clients. One of the most common recommendations to improve graduate education was to invite TGNC speakers to share their experiences. The majority of respondents identified a need for improvement of gender diversity education in SLP graduate programs. Further research is needed to determine the efficacy of different curricula in increasing the knowledge and skills of SLP graduates specific to TGNC clients to ensure clinical competency and equitable care
Intergenerational Pathways From Reflective Functioning to Infant Attachment Through Parenting
The aim of this prospective study was to examine temporal pathways from mothersâ reflective functioning (RF) through parenting to infant attachment measured more than 16 months later. Participants were 88 motherâinfant dyads from demographically diverse backgrounds and included a group of mothers with histories of childhood maltreatment. RF was assessed using the RF rating of the Adult Attachment Interview before the birth of the baby. Parenting was assessed when the infants were 6 months old using the Maternal Sensitivity scale, as well as when they were 16 months using the Disconnected and Extremely Insensitive Parenting scale. Infant attachment was assessed when the infants were 16 months old using the Strange Situation. As hypothesised, the study findings showed that mothersâ mentalization regarding their own early attachment relationships was associated with later parenting and infant attachment. Negative parenting behaviours explained the link between mothersâ RF about their own attachment relationships and infant attachment disorganization. The findings suggest that mothersâ mentalization about their early attachment relationships has important implications in the transition to becoming parents themselves. Mentalization appears to be particularly important in helping mothers screen and inhibit negative parenting behaviours that would otherwise undermine infant attachment security and organization
Measurement of the Integrated Faraday Rotations of BL Lac Objects
We present the results of multi-frequency polarization VLA observations of
radio sources from the complete sample of northern, radio-bright BL Lac objects
compiled by H. Kuhr and G. Schmidt. These were used to determine the integrated
rotation measures of 18 objects, 15 of which had never been measured
previously, which hindered analysis of the intrinsic polarization properties of
objects in the complete sample. These measurements make it possible to correct
the observed orientations of the linear polarizations of these sources for the
effect of Faraday rotation. The most probable origin for Faraday rotation in
these objects is the Galactic interstellar medium. The results presented
complete measurements of the integrated rotation measures for all 34 sources in
the complete sample of BL Lac objects.Comment: 9 pages, 7 figure
Determination of complex dielectric functions of ion implanted and implantedâannealed amorphous silicon by spectroscopic ellipsometry
Measuring with a spectroscopic ellipsometer (SE) in the 1.8â4.5 eV photon energy region we determined the complex dielectric function (Ï” = Ï”1 + iÏ”2) of different kinds of amorphous silicon prepared by selfâimplantation and thermal relaxation (500â°C, 3 h). These measurements show that the complex dielectric function (and thus the complex refractive index) of implanted aâSi (iâaâSi) differs from that of relaxed (annealed) aâSi (râaâSi). Moreover, its Ï” differs from the Ï” of evaporated aâSi (eâaâSi) found in the handbooks as Ï” for aâSi. If we use this Ï” to evaluate SE measurements of ion implanted silicon then the fit is very poor. We deduced the optical band gap of these materials using the DavisâMott plot based on the relation: (Ï”2E2)1/3 ⌠(Eâ Eg). The results are: 0.85 eV (iâaâSi), 1.12 eV (eâaâSi), 1.30 eV (râaâSi). We attribute the optical change to annihilation of point defects
Post-traumatic stress disorder in sexually abused children: secure attachment as a protective factor
The aim of the present study was to examine the hypothesis that attachment and CSA interacted such that school aged CSA survivors with insecure attachment to parents would be at an elevated risk of developing PTSD and trauma symptoms. Participants (n = 111, ages 7-12) comprised two groups, child CSA survivors (n = 43) and a matched comparison group of children (n = 68) recruited from the community. Children completed the Child Attachment Interview as well as the Trauma Symptom Checklist for Children (TSCC). There was a significant interaction between sexual abuse history and attachment security, such that sexually abused children with insecure attachment representations had significantly more PTSD and trauma symptoms than sexually abused children with secure attachment to parents. The findings show that using a dual lens of attachment and CSA can facilitate identification children most at risk have important implications for understanding risk and resilience processes
Properties of the warm magnetized ISM, as inferred from WSRT polarimetric imaging
We describe a first attempt to derive properties of the regular and turbulent
Galactic magnetic field from multi-frequency polarimetric observations of the
diffuse Galactic synchrotron background. A single-cell-size model of the thin
Galactic disk is constructed which includes random and regular magnetic fields
and thermal and relativistic electrons. The disk is irradiated from behind with
a uniform partially polarized background. Radiation from the background and
from the thin disk is Faraday rotated and depolarized while propagating through
the medium. The model parameters are estimated from a comparison with 350 MHz
observations in two regions at intermediate latitudes done with the Westerbork
Synthesis Radio Telescope. We obtain good consistency between the estimates for
the random and regular magnetic field strengths and typical scales of structure
in the two regions. The regular magnetic field strength found is a few
microGauss, and the ratio of random to regular magnetic field strength is 0.7
+/- 0.5, for a typical scale of the random component of 15 +/- 10 pc.
Furthermore, the regular magnetic field is directed almost perpendicular to the
line of sight. This modeling is a potentially powerful method to estimate the
structure of the Galactic magnetic field, especially when more polarimetric
observations of the diffuse synchrotron background at intermediate latitudes
become available.Comment: 12 pages, 6 figures, accepted by A&
Multi-frequency polarimetry of the Galactic radio background around 350 MHz: I. A region in Auriga around l = 161, b = 16
With the Westerbork Synthesis Radio Telescope (WSRT), multi-frequency
polarimetric images were taken of the diffuse radio synchrotron background in a
region centered on (l,b) = (161,16). The observations were done simultaneously
in 5 frequency bands from 341 MHz to 375 MHz, with 5 arcmin resolution.
Ubiquitous structure on arcminute and degree scales in the polarized intensity
and polarization angle, combined with no observed structure in total intensity,
indicates that the structure in the polarized radiation must be due to Faraday
rotation and depolarization mostly in the warm nearby Galactic interstellar
medium (ISM). Beam depolarization most likely creates "depolarization canals"
of one beam wide, while depth depolarization is responsible for creating most
of the structure on scales larger than a beam width. Rotation measures RM are
in the range -17 < RM < 10 rad/m2 with a non-zero average of about -3.4 rad/m2.
The gradient and average RM are consistent with a regular magnetic field of
about 1 uG which has a pitch angle of p = -14 degrees. 13 Extragalactic sources
in the field have |RM| < 13 rad/m2, with an estimated intrinsic source
contribution of 3.6 rad/m2. The RMs of the extragalactic sources show a
gradient (with a sign reversal) that is about 3 times larger than the gradient
in the RMs of the diffuse emission, and that is approximately in Galactic
latitude. This difference is ascribed to a vastly different effective length of
the line of sight. The observations are interpreted in terms of a
single-cell-size model of the warm ISM which contains gas and magnetic fields,
with a polarized background.Comment: 15 pages, 14 figures, to be published in A&
Assessing Reflective Parenting in Interaction with School-Aged Children
The aim of this study was to examine whether it was to develop a reliable and valid assessment of reflective parenting implicit in interaction with school-aged children using an adaptation of the Squiggle paradigm developed by Winnicott and a manualized coding system. A total of 158 mother-child dyads participated when children were aged 5-12. Of this group, 89 children had experienced sexual abuse (CSA). Inter -rater reliability using the manualized coding system was excellent. The factor analysis identified a Reflective Parenting Stance factor, in addition to an Affectionate Support factor and a Negative Parenting factor. Furthermore, there was a medium strength relationship between the motherâs Reflective Parenting Stance evident in her interactions with her child and parental reflective functioning assessed using the Parent Development Interview, suggesting the Parental Reflective Stance is a good indicator of parental reflective functioning in interaction. With regard to parent reports of child internalizing and externalizing behaviors, the Reflective Parenting Stance, was the only predictor of internalizing difficulties and a significant predictor of externalizing difficulties in addition to CSA
Simultaneous Denoising and Motion Estimation for Low-dose Gated PET using a Siamese Adversarial Network with Gate-to-Gate Consistency Learning
Gating is commonly used in PET imaging to reduce respiratory motion blurring
and facilitate more sophisticated motion correction methods. In the
applications of low dose PET, however, reducing injection dose causes increased
noise and reduces signal-to-noise ratio (SNR), subsequently corrupting the
motion estimation/correction steps, causing inferior image quality. To tackle
these issues, we first propose a Siamese adversarial network (SAN) that can
efficiently recover high dose gated image volume from low dose gated image
volume. To ensure the appearance consistency between the recovered gated
volumes, we then utilize a pre-trained motion estimation network incorporated
into SAN that enables the constraint of gate-to-gate (G2G) consistency. With
high-quality recovered gated volumes, gate-to-gate motion vectors can be
simultaneously outputted from the motion estimation network. Comprehensive
evaluations on a low dose gated PET dataset of 29 subjects demonstrate that our
method can effectively recover the low dose gated PET volumes, with an average
PSNR of 37.16 and SSIM of 0.97, and simultaneously generate robust motion
estimation that could benefit subsequent motion corrections.Comment: Accepted at MICCAI 202
