Dear Mr. Lindseth: 

Attached please find copies of regression equations that were 

requested at the deposition of Dr. JoMills H. Braddock, taken 

earlier this fall in Miami, Florida. 

We have diligently attempted to track down the additional 

three documents that you requested by letter dated December 10, 

1992, with the following results: 

1. Braddock, "Segregated High School Experiences and Black 

Students’ College and Major Field Choices:" Dr. Braddock presented 

a conference paper of this title. The paper has not been finalized 

or published. We are attempting to obtain a copy of the conference 

paper off of disk and, if we are successful by Monday, December 21, 

we will provide you with a copy. 

2 Braddock & McPartland (1987), "Some Cost and Benefit 

Considerations for Black College Students Attending Predominantly 

White and Black Universities," in M. Nettles, The Black Experience 

in Higher Education, Westport, Connecticut (Greenwood Press): Thus 

far, despite an exhaustive computer and library search, we have 

been unable to locate M. Nettles, The Black Experience in Higher 

Education. If we our search requests generate results on Monday, 

December 21, we will FAX a copy of the article. 

  

  

  

  

3. Braddock, McPartland, Trent (1984), "Desegregated Schools and 

Desegregated Work Environments": At the 1984 AERA conference, Dr. 

William Trent presented findings of research conducted by both Dr. 

Braddock and Dr. Trent. This presentation carried the title 

"Desegregated Schools and Desegregated Work." No final paper was 

published under this title.

As we discussed, due to Dr. Braddock'’s relocation and the 

hurricane that has so changed the regular course of events in 

Miami, Dr. Braddock has been unable to unpack his boxes and locate 

older documents. These circumstances have adversely affected our 

ability to locate the requested materials. 

Sincerely,
