    Men Fall Behind in College Enrollment.

    Women Still Play Catch-Up at Work.


        The coronavirus upended the lives of millions of college students. The Wall Street Journal reported this week that men have been hit particularly hard — accounting for roughly three-fourths of pandemic-driven dropouts — and depicted an accelerating crisis in male enrollment.

         A closer look at historical trends and the labor market reveals a more complex picture, one in which women keep playing catch-up in an economy structured to favor men.

        In many ways, the college gender imbalance is not new. Women have outnumbered men on campus since the late 1970s. The ratio of female to male undergraduates increased much more from 1970 to 1980 than from 1980 to the present. And the numbers haven’t changed much in recent decades. In 1992, 55 percent of college students were women. By 2019, the number had nudged up to 57.4 percent.

        While the shift in the college gender ratio is often characterized as men “falling behind,” men are actually more likely to go to college today than they were when they were the majority, many decades ago. In 1970, 32 percent of men 18 to 24 were enrolled in college, a level that was most likely inflated by the opportunity to avoid being drafted into the Vietnam War. That percentage dropped to 24 percent in 1978 and then steadily grew to a stable 37 percent to 39 percent over the last decade.

        The gender ratio mostly changed because female enrollment increased even faster, more than doubling over the last half-century.

        Because of the change in ratio, some selective colleges discriminate against women in admissions to maintain a gender balance, as The Journal reported. Generally, admissions officials prefer to limit the disparity to 55 percent female and 45 percent male. Their reason not to let the gender ratio drift further toward 2 to 1 is straightforward: Such a ratio would most likely cause a decrease in applications.

        In a New York Times essay in 2006 titled “To All the Girls I’ve Rejected,” the dean of admissions at Kenyon College at the time explained: “Beyond the availability of dance partners for the winter formal, gender balance matters in ways both large and small on a residential college campus. Once you become decidedly female in enrollment, fewer males and, as it turns out, fewer females find your campus attractive.”

        The raw numbers don’t take into account the varying value of college degrees. Men still dominate in fields like technology and engineering, which offer some of the highest salaries for recent graduates. Perhaps not coincidentally, the professors in those fields remain overwhelmingly male.

        Women surged into college because they were able to, but also because many had to. There are still some good-paying jobs available to men without college credentials. There are relatively few for such women. And despite the considerable cost in time and money of earning a degree, many female-dominated jobs don’t pay well.

        The fact that the male-female wage gap remains large after more than four decades in which women outnumbered men in college strongly suggests that college alone offers a narrow view of opportunity. Women often seem stuck in place: As they overcome obstacles and use their degrees to move into male-dominated fields, the fields offer less pay in return.

        None of this diminishes the significance of the male decrease in college enrollment and graduation. Educators view the male-driven dive in community college enrollment over the last 18 months as a calamity. The pandemic confirmed what was already known. Higher socioeconomic classes are deeply embedded in college and will bear considerable cost and inconvenience to stay there, even if it means watching lectures on a laptop in the room above your parent’s garage and missing a season of parties and football games.

        For other people, college attendance is far more fragile. It does not define their identities and is not as important as earning a steady paycheck or starting and nurturing a family. In a time of crisis, it can be delayed — but the reality is that people who drop out of college are statistically unlikely to complete a degree.

        Last year, women were less likely than men to leave community college, despite their disproportionate responsibility for caregiving and domestic work, because they no doubt understood the bleak long-term job prospects for women without a credential.

    Se i é o número complexo cujo quadrado é igual a -1, e é o número irracional que é a base do logaritmo natural, e α é um número real, podemos definir eiα como sendo igual a cosα + i senα. Em particular, se α = π, segue que eiπ + 1 = 0. Apresentada por Leonardo Euler, esta é uma das mais belas expressões matemáticas envolvendo os números e, 1, π e 0 (zero). Se z é um número complexo não nulo, r é o módulo de z e α é o argumento principal de z, então, podemos facilmente verificar que z = reiα. Ao apresentarmos o número complexo z = -1 - √3 i, nesta forma, teremos

    No Brasil, os veículos automotores mais antigos, com quatro rodas ou mais, são identificados com placas nas quais são gravados sete dígitos, sendo três letras seguidas de quatro algarismos arábicos (por exemplo GAV 5613). Atualmente os veículos novos são identificados com placas do chamado padrão Mercosul, que também utiliza sete dígitos. A diferença é que, de acordo com esse padrão, o segundo algarismo da esquerda para a direita é substituído por uma das vinte e seis letras do alfabeto português (por exemplo GAV 5M13). Considerando que pode haver repetição dos dígitos, o número total de placas padrão Mercosul que podem ser produzidas é
