First-Principle Wannier function analysis of the electronic structure of PdTe: Weaker magnetism and superconductivity

We report a first-principles Wannier function study of the electronic structure of PdTe. Its electronic structure is found to be a broad three-dimensional Fermi surface with highly reduced correlations effects. In addition, the higher filling of the Pd $d$-shell, its stronger covalency resulting from the closer energy of the Pd-$d$ and Te-$p$ shells, and the larger crystal field effects of the Pd ion due to its near octahedral coordination all serve to weaken significantly electronic correlations in the particle-hole (spin, charge, and orbital) channel. In comparison to the Fe Chalcogenide e.g., FeSe, we highlight the essential features (quasi-two-dimensionality, proximity to half-filling, weaker covalency, and higher orbital degeneracy) of Fe-based high-temperature superconductors.Comment: 5 Pages, 3 Figure

Collegiate Basketball Season-Ticket Holders’ Purchasing Motivation and Interests

This study examined the ticket purchasing motivation and interests of 334 season-ticket holders (199 males, 135 females) from two NCAA Division-I regional state institutions. The participants’ purchasing motivation and interests were surveyed onsite in the 2008-9 season by utilizing a12-item self-created instrument with a high level of internal reliability. The results indicated that the participants’ ticket purchasing motivation was mainly influenced by the competition and psycho-social related factor (CPR) and price and promotion (P&P) factor. The researchers further addressed the unique aspects in promoting regional Division-I basketball programs, and limitations and directions for future studies

Simulation of Asynchronous Instruction Pipelines

This paper presents the ARAS simulator with which asynchronous instruction pipelines can be modelled, simulated and displayed. ARAS allows one to construct instruction pipelines by preparing various configuration files. Using these files and a number of benchmark programs, performance of the instruction pipelines can be obtained. The performance of asynchronous instruction pipelines can also be compared to synchronous case. Thus, one can decide the optimal design for instruction pipelines in asynchornous or synchronous cases and explore the deisng space of asynchronous instruction pipeline architectures

Dataset associated with "Ocean Surface Flux Algorithm Effects on Tropical Indo-Pacific Intraseasonal Precipitation"

This dataset is for ocean surface flux diagnostic and to reproduce the analyses and figures in the manuscript "Ocean Surface Flux Algorithm Effects on Tropical Indo-Pacific Intraseasonal Precipitation". The time period is from 1998 to 2014 and focus on the ocean region between 20S-20N and 90E-180Surface latent heat fluxes help maintain tropical intraseasonal precipitation. We develop a latent heat flux diagnostic that depicts how latent heat fluxes vary with the near-surface specific humidity vertical gradient (dq) and surface wind speed (|V|). Compared to fluxes estimated from |V| and dq measured at tropical moorings and the COARE3.0 algorithm, tropical latent heat fluxes in the NCAR CEMS2 and DOE E3SMv1 models are significantly overestimated at |V| and dq extrema. MJO sensitivity to surface flux algorithm is tested with offline and inline flux corrections. The offline correction adjusts model output fluxes toward mooring-estimated fluxes; the inline correction replaces the original bulk flux algorithm with the COARE3.0 algorithm in atmosphere-only simulations of each model. Both corrections reduce the latent heat flux feedback to intraseasonal precipitation, in better agreement with observations, suggesting that model-simulated fluxes are overly supportive for maintaining MJO convection.Department of Energy : DE‐SC002009

Investing In Accounting: A Call For Professional Involvement In Higher Education

The current financial crisis has created serious repercussions for accounting education. Public universities have lost funding and initiated huge budget cuts. These drastic cutbacks have resulted in the losses of courses, enrollment, and faculty. These losses will translate into inaccessibility of education will reduce the future accounting work force. To recover from the recession, well trained accountants are critical to provide the financial fundamentals for businesses. While most of us understand that an investment in accounting education is an investment in successful business, effective practices for recruitment are needed in a time of scarce resources. In this paper, we would like to focus on the difficulties occurring in accounting education, which will negatively affect business. Furthermore, we would strongly encourage companies to continuously reach out to potential employees and support accounting education. Some suggestions are provided for cost saving avenues to reduce recruiting costs and develop high quality accounting professionals

Investigating the Use of Virtual Reality Headsets for Postural Control Assessment: An Instrument Validation Study

Accurately measuring postural sway is an important part of balance assessment and rehabilitation. Although force plates give accurate measurements, their costs and space requirements make their use impractical in many situations. The work presented in this paper aimed to address this issue by validating a virtual reality (VR) headset as a relatively low-cost alternative to force plates for postural sway measurement. The HTC Vive (HTC Corporation) VR headset has built-in sensors that allow for position and orientation tracking, making it a potentially e?ective tool for balance assessments. Participants in this study were asked to stand upright on a force plate (NeuroCom; Natus Medical Incorporated) while wearing the HTC Vive. Position data were collected from the headset and force plate simultaneously as participants experienced a custom-built VR environment that covered their entire field of view. The intraclass correlation coefficient (ICC) was used to examine the test-retest reliability of the postural control variables, which included the normalized path length, root mean square (RMS), and peak-to-peak (P2P) value. These were computed from the VR position output data and the center of pressure (COP) data from the force plate. Linear regression was used to investigate the correlations between the VR and force plate measurements. Our results showed that the test-retest reliability of the RMS and P2P value of VR headset outputs (ICC: range 0.285-0.636) was similar to that of the RMS and P2P value of COP outputs (ICC: range 0.228-0.759). The linear regression between VR and COP measures showed significant correlations in RMSs and P2P values. Based on our results, the VR headset has the potential to be used for postural control measurements. However, the further development of software and testing protocols for balance assessments is needed.ECU Open Access Publishing Support Fun

Characteristics Of Diligent Audit Committees

The mounting attention given to audit committees following a series of corporate financial reporting failures has resulted in numerous provisions within Sarbanes Oxley Act (SOX hereafter) of 2002. The SOX addresses aspects of the audit committee, including its authority and composition characteristics, but the requirement for minimum meeting frequency for the audit committee member was absent from the final SOX provision despite the recommendations of regulators. Since audit committee activity, or degree of audit committee diligence, is determined by the audit committee itself, we investigate various firm-level and governance attributes that likely influence audit committees’ choice to meet more often than anticipated.   After analyzing a sample of 2,715 firm-year observations spanning fiscal years 1998-2003, we find that audit committee diligence is positively associated with audit committee attributes such as financial expertise, but negatively association with audit committee tenure, suggesting that efficiency gains are enjoyed by audit committees as they become more familiar with firm-specific reporting issues. We also document positive associations between audit committee diligence and both governance and agency cost variables.  Finally, we document a significant increase in audit committee diligence in the years following the implementation of the SOX 2002 provisions
