The return to Harvard this fall of Theda R. Skocpol, the sociologist who fought a four-year tenure battle and won a sex discrimination grievance against the University, has precipitated new conflict within the Faculty of Arts and Sciences, professors said.

In interviews this week, faculty members said that Skocpol has alienated herself from other faculty members by publicly airing her differences with the University and pressing officials within the faculty to give her additional responsibilities.

Meanwhile, Skocpol said she has not been accorded the respect due her as a senior member of the faculty. Skocpol first expressed her sentiments in an article that appeared in last week's issue of The Chronicle of Higher Education, a weekly education newspaper.

"We had hoped the controversy would end when she received tenure, but she has intensified it," said Professor of Sociology Orlando Patterson, who said he supported Skocpol's bid for a permanent appointment.

Another senior professor, speaking on condition of anonymity, said Skocpol's "combative attitude" has posed "a great problem" for the department.

Professors condemned Skocpol's public perpetuation of the dispute in The Chronicle of Higher Education and criticized comments she made last month to the American Sociological Society.

During a speech to the group, Skocpol called her conflict with Harvard "a many-year game of chicken with the leaders of the most arrogant university in the Western World."

"Remarks of this kind are completely out of place. They destroy the community," said one senior department member who spoke on condition that he not be identified. "When one joins a university, one is supposed to join a community of scholars."

Skocpol's conflict with the University began in 1980, when she was denied tenure. She subsequently filed and won a grievance against Harvard charging that she had been a victim of sexual discrimination.

President Derek C. Bok offered Skocpol tenure, and she returned to Cambridge this year from the University of Chicago, where she had spent some of the intervening years as a full professor.

After accepting Bok's offer, Skocpol said, she requested and was denied an affiliation with Social Studies, a degree-granting program in which she advised students as a junior faculty member during the late 1970s.

Skocpol said this week that she was "just amazed" by a letter she received from David S. Landes, the chairman of the Social Studies program, in which Landes explained the reasons for his decision.

"You are coming into a depart- ment that voted against your appointment. Youhave been imposed upon it by a personal decisionof the President, an act that, to my knowledge, isunexampled in the modern history of this Faculty,"Landes wrote.

"You will have, therefore, many fences to mendbefore making a place for yourself. You will alsowant to prove yourself intellectually," Landescontinued. "Under the circumstances, it would beonly prudent not to undertake too much."
