Separation of \gamma/\pi^0 showers at high energies

We have designed and carried out simulation studies of a two layer Shower Maximum Detector diagonally off-set (SMD-dos) optimized for the separation of \pi^0 showers from \gamma showers in the 30 to 150 GeV energy range. For 90% \gamma acceptance the SMD-dos yields \pi^0 rejection efficiency of 92+-4%, 87+-4% and 32+-2%, respectively, for 30, 50 and 150 GeV incident energies. We find that the SMD-dos is superior to a conventional geometry single-layer or mutiple-layer shower maximum detector (SMD), of equal granularity, by an average factor of ~1.5 over the 50 to 150 GeV energy range. We also find that the SMD-dos gives better \pi^0 rejection, for the same number of channels, than a SMD. At hadron - hadron colliders the signature of choice for the detection of the Higgs particle, in the mass range of 120 to 160 GeV, is via the decay H-->\gamma\gamma. The addition of a SMD-dos to the planned detectors at the LHC would significantly reduce the background to the \gamma-signal coming from prolific \pi^0 production.Comment: 16 pages, 6 figures, LaTeX.

The Serving Supervisor: Supervisor Servant Leadership as a Protective Factor for Counseling Residents’ Burnout and Secondary Traumatic Stress

According to Stamm (2010), variables in counselors’ work environment, personal environment, and client environment precipitate the development of compassion fatigue. Compassion fatigue, which comprises secondary traumatic stress and burnout, is an occupational hazard for counselors, and new counselors are especially vulnerable. A supervisory style that exhibits servant leadership traits may provide necessary support and counteract compassion fatigue symptoms for counseling residents. Servant leadership shares many philosophical assumptions of the counseling profession and addresses the administrative challenges many clinical supervisors face today (Evans, Wright, Murphy, & Maki, 2016). A sample of 241 counseling residents participated in the study and completed several instruments. Data were analyzed with two structural equation models to identify the impact of the perceived servant leadership traits of supervisors on counseling residents’ compassion fatigue, burnout, and secondary traumatic stress with other relevant predictors. Limitations, avenues for future research, and implications for counselor education and supervision are discussed

Toward a Spectrum of Moral Harm: A New Paradigm

Moral harm is the pain, anguish, or trauma experienced as a result of violations to one’s value system. Researchers have analyzed the experience of moral harm through the lenses of moral injury among military personnel, and moral distress among helping professionals. Although both fields of research share similar frames of reference, the current project is the first known work to conceptualize moral injury and moral distress within the same theoretical model. The authors posit that moral injury and moral distress are experiences along a spectrum; both struggle and recovery can be understood within this context. Implications for ethical practice and future research are discussed

The Impact of Supervisor Servant Leadership on Counselor Supervisee Burnout and Secondary Traumatic Stress

This study investigates the prediction of supervisee burnout and secondary traumatic stress by perceived supervisor servant leadership. Authors hypothesized that the servant leadership of supervisors would predict diminished burnout and secondary traumatic stress of supervisees. A sample of 241 counseling supervisees participated in the cross-sectional study and completed instruments measuring burnout, secondary traumatic stress, and perceived servant leadership of their direct supervisors. Data were analyzed with two simple linear regressions, and a one-way MANOVA was performed to determine if supervisee burnout, supervisee secondary traumatic stress, and perceived servant leadership of supervisors differed significantly according to supervisor type (i.e., clinical, administrative, or dual role). Results confirmed the main hypothesis, and administrative supervisors were perceived to demonstrate significantly less servant leadership qualities than the other two supervisor types. Limitations, avenues for future research, and implications for counselor education and supervision are discussed
