Introduction to Animal Therapy and its Related Tax Benefits

How are animals being used to improve the emotional and physical health of individuals? What are the tax implications associated with service and therapy animals? We examine these questions by providing an introduction to the subject of Animal Assisted Therapy, including how therapists and counselors are routinely using therapy animals in both individual and group treatment settings. Additionally, we discuss the potential tax savings that may be available to counselors and their clients who are using service and therapy animals. We also offer recommendations and guidance for counselors who wish to incorporate animal therapy into their treatment options

Six-body Light-Front Tamm-Dancoff approximation and wave functions for the massive Schwinger model

The spectrum of the massive Schwinger model in the strong coupling region is obtained by using the light-front Tamm-Dancoff (LFTD) approximation up to including six-body states. We numerically confirm that the two-meson bound state has a negligibly small six-body component. Emphasis is on the usefulness of the information about states (wave functions). It is used for identifying the three-meson bound state among the states below the three-meson threshold. We also show that the two-meson bound state is well described by the wave function of the relative motion.Comment: 19 pages, RevTeX, 7 figures are available upon request; Minor errors have been corrected; Final version to appear in Phys.Rev.

Can Using the Internal Audit Function as a Training Ground for Management Deter Internal Auditor Fraud Reporting?

This study examines the effects of using the internal audit function as a training ground for management and fraud magnitude on internal auditor fraud reporting decisions. Using a 2x2 between-participants experiment, the current study manipulates the use of the internal audit function as a management training ground (used as a training ground vs. not used as a training ground) and fraud magnitude (large fraud, defined as 30 percent of net income vs. small fraud, defined as one percent of net income). The results indicate that internal auditors may be less likely to report a fraud to their superior when the internal auditors are being groomed for management positions. No effect is found for fraud magnitude, as respondents indicated a similar willingness to report small frauds as large frauds. These findings contribute to the whistleblowing literature and the internal audit objectivity literature by demonstrating that undesirable repercussions associated with using the internal audit function as a management training ground can extend to the internal auditor fraud reporting decision

RPA for Light-Front Hamiltonian Field Theory

A self-consistent random phase approximation (RPA) is proposed as an effective Hamiltonian method in Light-Front Field Theory (LFFT). We apply the general idea to the light-front massive Schwinger model to obtain a new bound state equation and solve it numerically.Comment: A major revision in presentation, while the results essentially unchanged. 2 figs. replaced, 1 fig. added, some parts of Sec.

The Vacuum in Light-Cone Field Theory

This is an overview of the problem of the vacuum in light-cone field theory, stressing its close connection to other puzzles regarding light-cone quantization. I explain the sense in which the light-cone vacuum is ``trivial,'' and describe a way of setting up a quantum field theory on null planes so that it is equivalent to the usual equal-time formulation. This construction is quite helpful in resolving the puzzling aspects of the light-cone formalism. It furthermore allows the extraction of effective Hamiltonians that incorporate vacuum physics, but that act in a Hilbert space in which the vacuum state is simple. The discussion is fairly informal, and focuses mainly on the conceptual issues. [Talk presented at {\sc Orbis Scientiae 1996}, Miami Beach, FL, January 25--28, 1996.

Proton induced thermal stress-wave measurements using a Laser Doppler Vibrometer

Abstract.: Thermal stress-waves are generated in the solid target material when the proton beam interacts. These stress waves excite natural oscillations of the target or cause plastic deformations. Hence, an experimental setup with a laser Doppler vibrometer [CITE] was developed to investigate free surface vibrations of cylindrical targets. The target configurations for RIB and conventional neutrino beams (CNGS project) were investigated to analyze proton induced thermal stress-wave generation and propagatio

Dynamic MAIT cell response with progressively enhanced innateness during acute HIV-1 infection.

Mucosa-associated invariant T (MAIT) cell loss in chronic HIV-1 infection is a significant insult to antimicrobial immune defenses. Here we investigate the response of MAIT cells during acute HIV-1 infection utilizing the RV217 cohort with paired longitudinal pre- and post-infection samples. MAIT cells are activated and expand in blood and mucosa coincident with peak HIV-1 viremia, in a manner associated with emerging microbial translocation. This is followed by a phase with elevated function as viral replication is controlled to a set-point level, and later by their functional decline at the onset of chronic infection. Interestingly, enhanced innate-like pathways and characteristics develop progressively in MAIT cells during infection, in parallel with TCR repertoire alterations. These findings delineate the dynamic MAIT cell response to acute HIV-1 infection, and show how the MAIT compartment initially responds and expands with enhanced function, followed by progressive reprogramming away from TCR-dependent antibacterial responses towards innate-like functionality
