School Counselors and Secondary Exposure to Trauma: Exploring the Relationships Between Empathy, Self-efficacy, Burnout, Secondary Traumatic Stress, and Compassion Satisfaction

Secondary exposure to trauma has been found to be related to increased burnout and secondary traumatic stress among professionals who work with clients who have experienced trauma (Bride, 2007; Brady, 2008; Peltzer, Matseke, & Louw, 2014; Shoji et al., 2015). Interpersonal factors such as self-efficacy and empathy may support those who experience secondary exposure to trauma by reducing burnout and secondary traumatic stress, and increasing compassion satisfaction (Shakespeare-Finch, Rees, & Armstrong, 2015; Wagaman, Geiger, Shockley, & Segal, 2015). School counselors have not been included in previous studies related to secondary exposure to trauma; however, their professional role in providing support to students in schools places them in direct contact with children and adolescents who have experienced traumatic events. This study investigated the relationships among secondary exposure to trauma, self-efficacy, empathy, and professional quality of life (i.e. burnout, secondary traumatic stress, and compassion satisfaction) for school counselors. A correlation analysis indicated that self-efficacy and empathy were both significantly correlated with burnout and compassion satisfaction. Self-efficacy and secondary exposure to trauma were both significantly correlated with secondary traumatic stress. Hierarchical linear regression analyses revealed that self-efficacy and empathy were predictors of burnout and compassion satisfaction and self-efficacy and secondary exposure to trauma were predictors of secondary traumatic stress. Implications and recommendations for professional school counselors and school counselor educators are provided

Time-resolved optical/near-IR polarimetry of V404 Cyg during its 2015 outburst

We present optical and near-IR linear polarimetry of V404 Cyg during its 2015 outburst and in quiescence. We obtained time resolved r'-band polarimetry when the source was in outburst, near-IR polarimetry when the source was near quiescence and multiple wave-band optical polarimetry later in quiescence. The optical to near-IR linear polarization spectrum can be described by interstellar dust and an intrinsic variable component. The intrinsic optical polarization, detected during the rise of one of the brightest flares of the outburst, is variable, peaking at 4.5 per cent and decaying to 3.5 per cent. We present several arguments that favour a synchrotron jet origin to this variable polarization, with the optical emission originating close to the jet base. The polarization flare occurs during the initial rise of a major radio flare event that peaks later, and is consistent with a classically evolving synchrotron flare from an ejection event. We conclude that the optical polarization flare represents a jet launching event; the birth of a major ejection. For this event we measure a rather stable polarization position angle of -9 degrees E of N, implying that the magnetic field near the base of the jet is approximately perpendicular to the jet axis. This may be due to the compression of magnetic field lines in shocks in the accelerated plasma, resulting in a partially ordered transverse field that have now been seen during the 2015 outburst. We also find that this ejection occurred at a similar stage in the repetitive cycles of flares.Comment: 9 pages, 5 figures, accepted for publication by MNRA

Turbulence Model Implementation and Verification in the SENSEI CFD Code

This paper outlines the implementation and verification of the negative Spalart-Allmaras turbulence model into the SENSEI CFD code. The SA-neg turbulence model is implemented in a flexible, object-oriented framework where additional turbulence models can be easily added. In addition to outlining the new turbulence modeling framework in SENSEI, an overview of the other general improvements to SENSEI is provided. The results for four 2D test cases are compared to results from CFL3D and FUN3D to verify that the turbulence models are implemented properly. Several differences in the results from SENSEI, CFL3D, and FUN3D are identified and are attributed to differences in the implementation and discretization order of the boundary conditions as well as the order of discretization of the turbulence model. When a solid surface is located near or intersects an inflow or outflow boundary, higher order boundary conditions should be used to limit their effect on the forces on the surface. When the turbulence equations are discretized using second order spatial accuracy, the edge of the eddy viscosity profile seems to be sharper than when a first order discretization is used. However, the discretization order of the turbulence equation does not have a significant impact on output quantities of interest, such as pressure and viscous drag, for the cases studied
