Computer Graphics and Animation at The Ohio State University.

The research and production of computer graphics imagery and animation at The Ohio State University started with the artistic work of Prof. Charles Csuri. He developed the Computer Graphics Research Group in response to the award of a National Science Foundation Grant in 1974, and the group transferred its technology to a commercial production effort, Cranston/Csuri Productions, Inc.

Using the Rasch measurement model to design a report writing assessment instrument.

This paper describes how the Rasch measurement model was used to develop an assessment instrument designed to measure student ability to write law enforcement incident and investigative reports. The ability to write reports is a requirement of all law enforcement recruits in the state of Michigan and is a part of the state's mandatory basic training curriculum, which is promulgated by the Michigan Commission on Law Enforcement Standards (MCOLES). Recently, MCOLES conducted research to modernize its training and testing in the area of report writing.

Locating a site on the maize B chromosome that controls preferential fertilization.

In maize, the B chromosome can undergo nondisjunction at the second pollen mitosis, producing sperm with two B chromosomes and sperm with zero B chromosomes. Preferential fertilization is the ability of the sperm carrying two B chromosomes to transmit more frequently to the embryo of a kernel than the sperm lacking the B chromosome. A translocation involving the B chromosome and chromosome 9, TB-9Sb, has been used to study preferential fertilization.

Unstable inheritance of maize B-type chromosomes that lack centric heterochromatin.

The B chromosome of maize undergoes frequent non-disjunction at the second pollen mitosis. In B-A translocations, the B-A chromosome retains the capacity for non-disjunction. We have collected deletion-derivative TB-9Sb stocks.
