Mayor Marion Barry, saying that creating jobs would be a top priority, officially was sworn in yesterday to his second term, along with newly elected City Council Chairman David A. Clarke and five other council members.

"Jobs and more jobs has to be a high priority," Barry said in an interview after the brief swearing-in ceremony in the council chambers at the District Building. "It's hard to have self-respect and hold a family together without a job . . . Any time anyone's out of work you've got to be concerned about it."

D.C. Superior Court Chief Judge H. Carl Moultrie I administered the oath to Barry, Clarke and the other council members at the ceremony that was a prelude to an elaborate series of inaugural events today.

The $150,000 inaugural festivities include a prayer breakfast at the Washington Hilton Hotel for more than 2,000 people, a parade that will wind past the District Building, a public re-enactment of the swearing-in ceremony, and a ball at the new Washington Convention Center.

Other council members who were sworn in yesterday were Frank Smith Jr. (D-Ward 1), a school board member elected to Clarke's old seat; and incumbents Polly Shackleton (D-Ward 3); William R. Spaulding (D-Ward 5); Betty Ann Kane (D-At-Large); and Hilda Mason (Statehood-at-Large).

Council member Nadine P. Winter (D-Ward 6), who also was elected in November to a new term, boycotted the District Building ceremony because, she said, she was told she would not be allowed to invite many of her relatives, friends and constituents. She said she held her own event at the Union Temple Baptist Church, 14th and U streets SE and was sworn in by D.C. Superior Court judge Annice Wagner.

Winter said the church is located in precinct 114, one of two that she lost by less than 100 votes in the Sept. 14 Democratic primary. Local merchants donated flowers and food for her ceremony, Winter said.

At the District Building, harpist Victoria Payton entertained about 150 friends, family members, and aides of the mayor and council members gathered for the swearing-in ceremony, which by law had to be held on Jan. 2.

Barry, looking very much at ease as he smiled and joked with members of the audience, was accompanied by his wife, Effi, and their son, Christopher. The mayor didn't bring a Bible with him for the ceremony and ended up borrowing one from Kane, a challenger to Barry during part of the 1982 mayoral campaign.

Clarke, standing with his wife, Carol, declined to place his hand on a Bible in taking the oath of office and chose to use the word "affirm" instead of "swear." Clarke said later that he doesn't believe in mixing religious oaths with civil ceremonies.

Clarke said the council would have to develop unity among its members and work closely with Barry to tackle such pressing problems as unemployment, the shortage of decent housing, and crime.

"We're going to try to get into a debating framework rather than a divisive framework," Clarke said.

Arrington L. Dixon, defeated by Clarke for the council chairmanship, attended the ceremony and later hugged several of his friends and supporters. It was a bittersweet moment for Dixon, who launched his unsuccessful reelection campaign in the chambers and was introduced yesterday for the first time as "former chairman Arrington Dixon."

Officials and guests later mingled in the hallway outside the chambers, sipping champagne and munching on small sandwiches, vegetables and brownies.

Although the officials held off speeches until the inaugural events today, Barry repeatedly mentioned the importance of bolstering his jobs and economic development efforts.

Max N. Berry, chairman of the Pennsylvania Avenue Development Corporation (PADC) and one of the mayor's fund-raisers, said after the ceremony yesterday that "talk is cheap" and the mayor intends to move quickly to revitalize deteriorated commercial and industrial areas of the city.

"The mayor and the council are doing their homework and now they've got to turn that into law to provide incentives to businesses to stay in the city and to expand," Berry said.

Berry said he has urged the administration to create separate neighborhood development corporations, similar to the PADC, to revive areas such as parts of Anacostia and the New York Avenue corridor.

Today's inaugural events begin with the 7:30 a.m. prayer breakfast at the Washington Hilton. Nervous inaugural officials invited all 13 members of the council to spend Sunday night at the Hilton so the breakfast would begin on time. At least three members--Kane, Shackleton and John Ray (D-At-Large)--declined the invitation to use the $57-a-night rooms paid for by the inaugural committee.

The inaugural parade is scheduled to step off at 10:15 a.m. from a staging area at 7th Street and Constitution Avenue NW. The parade will travel on Constitution to 14th Street and pass in front of a reviewing stand at the District Building and then move north on 13th Street to the Convention Center.

The public swearing-in is scheduled to begin at 12:30 p.m. inside the Convention Center. The council is to hold its first formal meeting at 2:30 p.m. at the District Building, followed by small receptions in the council members' offices. The inaugural ball is scheduled from 9 p.m. until 1 a.m. at the Convention Center.

Officials said yesterday that all available passes for the swearing-in ceremony had been distributed but that tickets still were available for the prayer breakfast, at $15 each, and for the ball, at $35 each. Tickets can be purchased at the Adams Room of the Washington Hilton, officials said.
