The majority of these HBCUs are located in the southeast section of the United States. HBCUs are a major supplier of certified public accountants （CPAs） to the profession. Therefore, the performance of candidates from HBCUs should be of interest to various constituents including educators, employers, parents, students, and other stakeholders. The purpose of this paper is to provide statistical performance on the 2011 CPA examination for large, middle, and small HBCUs based upon the number of testing events taken. Taking a testing event is not the same as passing a testing event. This was the dichotomy between quantity and quality of HBCUs＇ performances. For large HBCUs, Morehouse University, North Carolina Agricultural and Technical State University （NC A＆T）, and Tennessee State University （TSU） were cited. For middle HBCUs, Albany State University, Norfolk State University （NSU）, and North Carolina Central University （NCCU） were cited. For small HBCUs, Alcorn State University, Fisk University, and University of Maryland Eastern Shore （UMES） were cited. The dichotomy between quantity and quality is real.展开更多

It could guarantee ship in safe and comfort. However, many design works did not involve simultaneously ship performances predictions in preliminary design. Moreover, ship designers sometimes modified a ship form to obtain proper design without ship performance consideration. Therefore, this study concerns on predictions of total resistance and added wave resistance of a ferry using a hybrid particle-grid method and then its motions response after modifying bow and stern parts by conducting experiment. Research results show total resistance and added wave resistance have a significant different, therefore, it would be an important consideration in determining ship powering in preliminary ship design. The non-dimensional added wave resistance increases in increasing wave length from λ/Lpp = 0.5 to 1.0 and it decreases after L/λ = 1.0. In addition, it tends to decrease caused by increasing ship speed. The comparison of averaged heave and pitch amplitudes between basic forms after modifying bow and stem parts is quiet similar. However, the rolling amplitude of the modified form is significantly higher comparing with the basic form. We conclude that a ship could be design in preliminary design take into account performances predictions by using numerical method and experimental work.展开更多
