The Effects of Changing AIS on User Experience and Business Role

Technology has become a dominant factor in many aspects of modern life. This research explores how technology has influenced the field of accounting through the advancement of Accounting Information Systems (AIS). To address the issue of the qualification of students entering the accounting profession, two populations were surveyed. Students who were previously enrolled in an AIS class at SUNY Brockport were surveyed about their comfort level with AIS before and after the class, along with their outlook on technology in the workforce. Accounting professionals were surveyed on their usage of systems in their companies, their preference towards change, and their first-hand accounts of changing technology in the workplace. The results of this research shows that while having an AIS class significantly helps prepare students for the real world, there are ways to improve the course content to provide even better professional candidates. To be successful, students must achieve a foundational grasp on system usage the same way that debits and credits are a foundation to the whole accounting cycle. Students should be exposed to a multitude of different accounting software so that they learn to move beyond “point and click” to a stage of analysis that will allow them to adapt to whatever systems they see later in their careers. For this to occur, either a second AIS class would be required, or a whole new major should be added, focusing on the importance of AIS. In the professional world, the changes in technology and AIS are causing restructuring of both the company structure and the human resource usage. Soon the new-hire data entry position will be obsolete as computers take over and the whole process becomes automated; thus ushering accounting into the age of analysis and forecasting as opposed to book keeping and data entry

Quasi One-Dimensional Modelling of Turbulence and Interaction of Combustion Chambers in a Shockless Explosion Combustor

This thesis deals with the modelling of two-dimensional coupling of quasi one-dimensional domains and turbulence within a quasi one-dimensional combustion chamber. Also an interpolation-free finite volume moving mesh method is described. First, the basic framework of a gas turbine is introduced including an uncommon approach for constant volume combustion: the shockless explosion combustion (SEC). In a preceding work a simulation code for this combustion process solving quasi one-dimensional reactive Euler equations with a finite volume (FV) Riemann solver has been developed and was extended for the thesis at hand. A network model is presented, allowing for the investigation of interaction of multiple pulsating combustion chambers of an SEC gas turbine with the plenums and each other. It couples the quasi one-dimensional domains using boundary conditions and flux corrections such that interactions of slanted combustion chambers with the plenums are possible. A series of simulations utilising this model is carried out to show possible fields of research for this tool. As the simulation of combustion processes are especially sensitive to spacial resolution but complex chemistry also imposes restrictions on the number of grid cells a feature for adaptive remeshing is described. It uses the moving mesh idea within the FV solver. As interpolation introduces too much numerical diffusion a flux correction is given which evolves governing equations and mesh simultaneously without changing the Euler equations themselves. The performance of this feature is demonstrated with simulations of a detonation and a cyclic SEC. Finally, the prerequisites for the research of the starting process of an SEC gas turbine are created by including molecular transport and turbulence in the SEC-code. Towards this aim, the one-dimensional turbulence (ODT) model is adjusted for this application. The ODT-line on which the stochastic eddy events, representing the turbulence, occur is aligned with the streamwise direction of the long-stretched combustion chamber. Also ODT is used as a stand-alone and subgrid-scale model. The main features of turbulence and ODT are compared to the new variant ODT-FHD. This study reveals that the ODT-FHD is able to generally reproduce the correct dependency of turbulence on mean flow velocity along with a plausible distribution of eddy sizes and kinetic energies. While lacking the possibility to generate new extrema of flow properties along the ODT-line it incorporates turbulent diffusion very well. The influence of the three model parameter is shown in addition to the simulation of a turbulent flame and a turbulent single-tube SEC

Exact one- and two-particle excitation spectra of acute-angle helimagnets above their saturation magnetic field

The two-magnon problem for the frustrated XXZ spin-1/2 Heisenberg Hamiltonian and external magnetic fields exceeding the saturation field Bs is considered. We show that the problem can be exactly mapped onto an effective tight-binding impurity problem. It allows to obtain explicit exact expressions for the two-magnon Green's functions for arbitrary dimension and number of interactions. We apply this theory to a quasi-one dimensional helimagnet with ferromagnetic nearest neighbor J1 < 0 and antiferromagnetic next-nearest neighbor J2 > 0 interactions. An outstanding feature of the excitation spectrum is the existence of two-magnon bound states. This leads to deviations of the saturation field Bs from its classical value Bs(classical) which coincides with the one-magnon instability. For the refined frustration ratio |J2/J1|> 0.374661 the minimum of the two-magnon spectrum occurs at the boundary of the Brillouin zone. Based on the two-magnon approach, we propose general analytic expressions for the saturation field Bs, confirming known previous results for one-dimensional isotropic systems, but explore also the role of interchain and long-ranged intrachain interactions as well as of the exchange anisotropy.Comment: 21 pages, 6 Figures. submitted to Phys.

The Effect of Intelligence Quotient Scores on Special Education Teacher Expectations for Job Success of the Mildly Handicapped

The primary purpose of this study was to determine whether intellectual deficiency connotes vocational deficiency in programming decisions made by educational personnel who work with secondary age mildly handicapped students. The influence of the two levels of job difficulty and teacher attitude toward the importance of academic skills for job success on educators\u27 judgements of vocational potential were also evaluated. Questionnaires were sent to 30 educators identified as leaders in secondary special education in the State of Washington. Analysis of the data revealed that educators rate the vocational potential of a mildly handicapped person with a high IQ (IQ= 80) as significantly greater than an individual with a low IQ (IQ= 52) even though both individuals have identical vocational skills

Measurement induced quantum walks on an IBM Quantum Computer

We study a quantum walk of a single particle that is subject to stroboscopic projective measurements on a graph with two sites. This two-level system is the minimal model of a measurement induced quantum walk. The mean first detected transition and return time are computed on an IBM quantum computer as a function of the hopping matrix element between the sites and the on-site potential. The experimentally monitored quantum walk reveals the theoretically predicted behavior, such as the quantization of the first detected return time and the strong increase of the mean first detected transition time near degenerate points, with high accuracy

Measurement of the elastic scattering cross section of neutrons from argon and neon

Background: The most significant source of background in direct dark matter searches are neutrons that scatter elastically from nuclei in the detector's sensitive volume. Experimental data for the elastic scattering cross section of neutrons from argon and neon, which are target materials of interest to the dark matter community, were previously unavailable. Purpose: Measure the differential cross section for elastic scattering of neutrons from argon and neon in the energy range relevant to backgrounds from (alpha,n) reactions in direct dark matter searches. Method: Cross-section data were taken at the Triangle Universities Nuclear Laboratory (TUNL) using the neutron time-of-flight technique. These data were fit using the spherical optical model. Results: The differential cross section for elastic scatting of neutrons from neon at 5.0 and 8.0 MeV and argon at 6.0 MeV was measured. Optical-model parameters for the elastic scattering reactions were determined from the best fit to these data. The total elastic scattering cross section for neon was found to differ by 6% at 5.0 MeV and 13% at 8.0 MeV from global optical-model predictions. Compared to a local optical-model for 40Ar, the elastic scattering cross section was found to differ from the data by 8% at 6.0 MeV. Conclusions: These new data are important for improving Monte-Carlo simulations and background estimates for direct dark matter searches and for benchmarking optical models of neutron elastic scattering from these nuclei
