<prompt> Fingqa isihloko: Izingane ezindala lapho ziqala isikole zingase zenze kahle esikoleni nasemphakathini esikhathini esifushane - kodwa maningi amathuba okuba ziyeke izifundo zazo futhi zenze ubugebengu zisencane. Iqembu labacwaningi base-US lafunda ngomphumela wokuya enkulisa ezinganeni ezizalwe ezinsukwini ezingu-60 ngaphambi kosuku lokuya enkulisa, nezingane ezizalwe ezinsukwini ezingu-60 ngemva kosuku lokuya enkulisa. Futhi bathola ukuthi le miphumela engemihle ithambekele kakhulu ezinganeni eziphuma ezindaweni ezingezinhle. Izingane ezinde lapho ziqala enkulisa isithombe sesitoko sikhonjisiwe zinamathuba amaningi okwenza kahle ezifundweni nasenhlalakahleni esikhathini esifushane, kodwa futhi zinamathuba amaningi okuthi zishiye izifundo zazo futhi zenze ubugebengu lapho ziseyizingane, kusho ucwaningo olusha. UPhilip Cook, uprofesa eSanford School of Public Policy yaseDuke University nomlobi oyinhloko walolu cwaningo, wathi: Lolu cwaningo lunikeza ubufakazi bokuqala obuqand ikhanda bokuhlobana okukhona phakathi kokuphuma esikoleni nobugebengu. Isekela umbono wokuthi imiphumela yobugebengu kufanele icatshangelwe ekuhloleni izinguquko zesikole. Iziboshwa ezishiya isikole ziningi kakhulu ejele, ngakho siyazi ukuthi kunokuhlobana okuqinile phakathi kokuyeka isikole nobugebengu. Kodwa ukuze kutholakale izimbangela, kudingeka ukuhlola. Ukuhlaziya kwami kusebenzisa ukuhlola kwemvelo okuhlobene nosuku lokuzalwa. UProfesa Cook noSongman Kang baseHanyang University eSeoul, eNingizimu Korea benza lolu cwaningo, olwanyatheliswa kuyi - American Economic Journal - Applied Economics. Kuthiwa kuwukucwaninga kokuqala okuhlobanisa ukuyeka isikole nobugebengu. Lolu cwaningo lwaqhathanisa abafundi besikole sikahulumeni saseNorth Carolina abazalwa ezinsukwini ezingu-60 ngaphambi, nezinsuku ezingu-60 ngemva kosuku lokuvalwa kwesikole. Ngesikhathi kwenziwa lolu cwaningo, izingane zakulesi sifundazwe kwakudingeka zibe neminyaka emihlanu ngo-October 16 ukuze zifanelekele ukungena enkulisa ngalowo nyaka. Ucwaningo luthi abafundi asebekhulile basengozini enkulu yokulahlwa icala lobugebengu ngaphambi kokuba babe neminyaka engu-20. Kuboniswa isithombe somshayeli osemusha ophuzile. Ngokuvamile izingane ziya enkulisa lapho zineminyaka emihlanu noma eyisithupha ubudala. Ucwaningo lwangaphambili luye lwasungula ukuthi izingane ezizalwa...  <response>: Ucwaningo lwabuka izingane eziqala enkulisa eNyakatho Carolina. Labo abajoyina lapho beseneminyaka eyisithupha kuneyisihlanu babizwa ngokuthi abadala ngokwebanga Lezi zinganeezindala zazenza kahle kakhulu esikoleni kwaze kwaba yilapho sezineminyaka engu - 16. Lolu cwaningo lwathola nokuthi babenamathuba aphansi ngesithathu okuzibandakanya ekuziphatheni kobugebengu besesesikoleni. Kodwa maningi amathuba okuthi bayeke futhi benze ubugebengu ngemva kweminyaka engu-16 ubudala.
