Unemployment, says the March 31 issue of Science magazine, is worse than the most down-in-the-mouth economists have hinted. Even cadavers are being thrown out of work.

While one might think that there isn't much a cadaver can do in the first place, one would be wrong. For the Department of Transportation cannily discovered that "Of all available surrogates for the human body, the cadaver possesses by far the greatest mechanical and geometrical similar with living person." So DOT put otherwise unoccupied cadavers to work determining how much protection airbags give in case of car crashes.

Unfortunately, none of this sat very well with Rep. John E. Moss (D-Calif.), whose personal opinion was "that the use of human cadavers for vehicle safety research violates fundamental notions of morality and human dignity, and must therefore be permanently stopped," at least until July 1, when a review of policy will be completed. Meanwhile, says a crash researcher, cadavers are being replaced by "living volunteers - but at lower cost." The Power and the Glory

Billy Graham, says William Martin in a thorough, fascinating profile in Texas Montly, is "the most successful evangelist in the history of Christianity." He has appeared before over 50 million people in person, his Decision magazine has a circulation of almost four million, several of his books have sold over 2 million each, his syndicated column is carried by over 200 daily newspapers with a circulation of 29 million, and as an added fillip, he is the only living person to be depicted in stained glass in the National Cathedral. Not bad for a dairy farmer's son who had a young women break up with him "because she did not think him sufficiently devout."

Graham got his big break during a 1949 Los Angeles revival, when press lord William Randolph Hearst "sent his influential chain of newspapers a simple telegram: 'Puff Graham.'" His continued success, says Martin, comes from three factors: "a simple nondenominational theology; a rational and efficient organization; and a distinctive personality and public style."

"Working a combination Jesus never quite mastered," Martin says, "he manages to comfort the afflicted without afflicting the comfortable." He has an organization so efficient that "for virtually every person who responds to Graham's invitation at an evening service, some pastor in a 60-mile radius will have received a letter by noon the following day urging him to contact the inquirer." But best of all, he fits what another writer said about a well-known evangelist of the 1800s: "He did not study the popular mind, he had it." I've Just Seen a Face

Four years ago, Ted Trikilis was almost broke; Pro Arts, the company he owned with his brother and an uncle, was not doing so hot either. By the end of 1977, Pro Arts was grossing $7 million annually and Trikilis was a millionaire. One poster and three little words made the difference: Farrah Fawcett-Majors.

How did Trikilis' company get involved with that lion-maned likeness? According to the April issue of Free Enterprise, it all started on a rainy Saturday in April, 1975 B.C.A. (Before Charlie's Angels), when Trikilis was at his farm planting apple trees. In between said plantings, Ted Partridge, an Akron University student who was giving him a hand, suggested a Farrah poster. "Farrah who " was Trikilis' immortal reply, so Partridge had to explain that she was in all these TV ads and that "the guys in the dorm are buying women's magazines just to cut out of her picture and pin it up on their wall."

"There were 900 guys in Partridge's dorm," Free Enterprise breathlessly reports," and on the principle that 900 college students can't be wrong, Ted called the William Morris Agency and tracked down the model's personal representative." Farrah's reaction to posing without a commercial product: "She thinks it would be cute."

And so it was. Ron's Back!

The Washington Journalism Review, nothing if not feisty and determined, has its third issue under its third guest editor just hitting the stands and featuring an exclusive interview with Ron Ziegler, late of the White House, who calls the new H. R. Haldeman book "shallow from the standpoint that he did not seem to have even at this point, a grasp of what happened during Watergate."

As for himself, Ziegler admits to being "used as a vehicle for the coverup," but still contends, "I never flatly said something I thought was a lie. I gave political answers. I gave answers that circumvented the question. And I did not always, as no press secretary can, give all of the information that I may have had on a given subject. I can say that I never stood at the podium and stated what I considered to be a blatantly false statement."

So much for contrition.

Much more upbeat is indefatigable WJR publisher Roger Kranz, who announces that the new issue is a fat 88 pages - poor MORE makes do with a mere 40 - and has benefited from a 150 percent increase in paid ads, which means that it will (fanfare) pay for itself.

Now if they can only find an editor. . . . A Word to the Wise

"The youth of the world are pointing the way to the new day which statesman have failed to bring . . . With their spirit, the old heaven and the old earth - suspicion and selfishness and hate - will pass away."

This points out John de Graaf in the March "Perils of the Path" issue of New Age, is not Charles Reich or Theododre Roszak praising today's counterculture, this is a man named Stanley High going on and on about the wandervogel youth cult that swept Germany in the 1920s stressing communes, occult sects and the wisdom of the East. "What is one to learn," de Graaf asks, "from the fact that High wrote in 1923 and ten years later Hitler was in power?"

Aside from the fact that the group's strident nonpolitical stance made it "impotent when disaster struck," de Graaf feels the main lesson is in how "Hitler formed an alternative youth movement that won adherents because it copied the trappings and rhetoric of the earlier counterculture. . . . The political movements of the Left must not, in their increased concern with economic issues, leave the question of alienation, the 'spiritual' realm, to the Jesus movement and to the popular psychologies of the 'human potential movement.'" War of the Roses

"Maybe you haven't noticed," writes John J. Terrant in the April 3 New York magazines, "but the United States has been struggling along for more than 200 years without a national flower." But fear not, "there are powerful forces bent in remedying that situation soon."

Most potent of the powerful are the rose partisans, commanded by one George Rose (no relation) who "showers facts and statistics on the interviewer like a soft rain of petals."

The rose has only one serious challenger left, the humble marigold, "a guerrilla band pitted against a mechanized army. Leaders of the band are Charlotte Bass, a self-styled "nutty housewife" from La Porte, Ind., and 85-year-old tycoon David Burpee, of Burpee Seeds, who back in 1975 paid $10,000 for the world's first full-scale, all-white marigold.

The marigold's biggest booster used to be Sen. Everett Dirkson, who packed the galleries when he discoursed on their marvels. Though his son-in-law, Howard Baker, has taken up the cudgels, the biggest problem seems to be that Congress somehow feels there are other things more worthy of its attention. But, as Charlotte Bass asks, "Why can't they for once do something happy?" Love Me Do

What are the 10 most important things in a marriage? Dr. Sol. Gordon lists them in Good Housekeeping as Love, Laughter, Talk, Involvement, Friendships, Integrity, Tolerance, Adaptability, Sex and Sharing. Why is sex so far down the list? Because Gordon considers it "the most grossly overrated 'privilege' of marriage . . ." to those who think otherwise, the doctor says, "break the engagement!" Buy Me

Magazine publishers are forever lookin for new people to aim magazines at, and the folks at McCall's think they've come up with a whopper: a publication for both men and women in their 20s. It's called Your Place and, says editor Kathleen Fury, "I hate to be hyperbolic, but its a revoluntionary idea that couldn't have been done 10 years ago."

In days of yore, Fury says, "you had 20 years of being a kid, a brief fling at independence, and then 20 years of being a parent." But now, "all kinds of options are opened up to people," including reading Your Place, and Fury thinks they ought to be taken advantage of. "I don't buy the notion that this is a narcissistic generation," she says. "There's an awful lot to be said for learning a lot about yourself."

Also aiming for a hot new audience is Gay Bryant, editor of New Dawn, who says unflinchingly that "there's a lot of money to be made if you can reach 'the new young woman' aged 18-34. I'm editing for Mary Tyler Moore at 23. I wouldn't want to have lunch with her, but she's a good market. If I can be to the new generation what Cosmopolitan was to the old, I'll be very successful.
