It is a relatively new subject, but not a new discipline since it brings together several mature fields of science including astronomy, geology, biology, and climatology. An understanding of the singular conditions that allowed the only example of life that we know exists to emerge and survive on our turbulent planet is essential if we are to seek answers to two fundamental questions facing humanity: will life (and especially human life) continue on Earth, and does life exist elsewhere in the universe?

As partners and family members were dispersed across national borders, interpersonal relationships were transformed. The prolonged absences of Mexican workers, mostly men, forced women and children at home to inhabit new roles, create new identities, and cope with long-distance communication from fathers, brothers, and sons. Drawing on an extraordinary range of sources, Ana Elizabeth Rosas uncovers a previously hidden history of transnational family life. Intimate and personal experiences are revealed to show how Mexican immigrants and their families were not passive victims but instead found ways to embrace the spirit (abrazando el espíritu) of making and implementing difficult decisions concerning their family situations-creating new forms of affection, gender roles, and economic survival strategies with long-term consequences. 410 0$aAmerican crossroads ;$v40. 606 $aForeign workers, Mexican$xFamily relationships$zUnited States$xHistory$y20th century 606 $aMigrant agricultural laborers$xFamily relationships$zUnited States$xHistory$y20th century 606 $aMexicans$zUnited States$xSocial conditions$y20th century 606 $aFamilies$zMexico$xSocial conditions$y20th century 606 $aImmigrant families$zUnited States$xSocial conditions$y20th century 607 $aMexico$xEmigration and immigration$xSocial aspects 607 $aUnited States$xEmigration and immigration$xSocial aspects 610 $a20th century american history. 610 $aaffection. 610 $aamerican crossroads series. 610 $aamerican immigration. 610 $abracero program. 610 $aeconomic struggles. 610 $afamily situations. 610 $afamily. 610 $afarm workers. 610 $afarming. 610 $agender roles. 610 $ahistory. 610 $aimmigration. 610 $ainterpersonal relationships. 610 $alabor history. 610 $alabor. 610 $along distance communication. 610 $alow wage farmers. 610 $amexican field workers. 610 $amexican immigrants. 610 $amexican workers. 610 $amexico. 610 $anational borders. 610 $apersonal experiences. 610 $aphysical workers. 610 $apolitical. 610 $aremittances. 610 $asurvival. 610 $atransnational family life. 610 $aunited states of america. 615 0$aForeign workers, Mexican$xFamily relationships$xHistory 615 0$aMigrant agricultural laborers$xFamily relationships$xHistory 615 0$aMexicans$xSocial conditions 615 0$aFamilies$xSocial conditions 615 0$aImmigrant families$xSocial conditions 676 $a305.8/6872073 700 $aRosas$b Ana Elizabeth$f1978-$01719051 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910810867403321 996 $aAbrazando el espi?ritu$94116526 997 $aUNINA
