Restitution has reportedly been made by one of four persons reprimanded in the wake of an investigation involving the North Texas State University physics department, and none of the four have filed appeals to the ad ministrative action ordered, according to university president C.C. Nolen. Three persons were assessed restitution as a part of the ad ministrative actions, but Nolen said he was not sure which of the three has submitted the payment. “To understand one check has been received,” he said, ‘‘but I have not seen .* Nov. 10, Nolen announced formal reprimands naming Dr. Jerome Duggan of the physics department faculty, Crawford Sloan, physics shop supervisor, and machinists James H. Cobb and Elvis McDaniel. He ordered restitution paid by Duggan, Sloan and Cobb and salary cuts for Duggan and Sloan. Nolen said Friday that he was unaware of any specific time period or deadlines for filing possible appeals to those actions through university channels. ‘‘But I would think it must be accomplished within the fiscal year that we are dealing with,’ he added. Administrative action ordered is immediate, Nolen said, and will not be delayed pending a possible appeal or its outcome. ‘‘We’ll take the action, and then they can appeal,’’ he explained. Salary reductions ordered ‘‘have been initiated,’’ Nolen said, but the paperwork involves several signatures ‘and I'm not sure that all the lines have been signed.” There is apparently no continuation of investigation into charges and countercharges that have emanated from within the physics department following announcement of the ad ministrative action, Nolen said. ‘What I have said is that we are receptive to any new evidence that might come to light,’ he added, ‘‘but thus far no new evidence has come to light that would change any action that has been taken.” That comment was in response to questions following publication of a formal statement released by Dr. Jim Sybert, physics department chairman, to the campus newspaper again questioning what Sybert termed an “unwarranted personal attack’ by physics professor Dr. Bruce Foster. In a memorandum distributed to faculty and administrative personnel last week, Foster sharply criticized the action against shop personnel, who he said were ‘scapegoats’ blamed for outside work “specifically authorized by both the former and present chairmen of the physics department.” In his formal statement to the North Texas Daily, Sybert pointed out the past months of intensive investigation of the physics department, and said he would “nonetheless ... welcome an instant and exhaustive inquiry into Dr. Foster's allegations by the president of the university or other authorities.” Sybert was quoted in the student newspaper as indicating that he had been in contact with Nolen and had received assurances that any in vestigation was underway on all fronts. In his memorandum, Foster wrote that he had contacted an ad ministrative official, after he became concerned that “administration con templated some action which would be a gross injustice to the shop personnel,” and told an official “all I knew about the involvement of the department chairman Foster later challenged statements from Sybert that alleged Foster's charges were based on his friendship with Sloan by commenting on his long friendship and support of Sybert, his former student.
