Some of the nation's biggest and most troubled cities began 1994 with new people in the mayor's office, each one vowing to turn things around.

In New York, Rudolph Giuliani began work on a program to make the nation's largest city safer. Detroit's Dennis Archer set about remaking a city ravaged by crime, budget problems and a poor national image. In Pittsburgh, Tom Murphy said his city needs a top-to-bottom turnaround to attract new business and visitors.Atlanta's new mayor, Bill Campbell, will be sworn in Monday.

Giuliani, a Republican who defeated Democrat David Dinkins, New York City's first black mayor, said he would add police foot patrols to ensure the safety of students.

In Detroit, Archer succeeds Coleman Young, who is suffering from emphysema and did not seek re-election to a sixth term.

Detroit faces a potential budget deficit of $88.5 million, an eroding population and business base, too much vacant housing and a crime rate that remains high, despite recent drops.

Pittsburgh's new mayor is a steelworker's son who has said he plans to develop vacant riverfront properties and expand high-tech industry.
