Ukuphindaphinda kwe-Moretti kushicilelwe ku-AER

I-Replication Imperative: I-Landmark Study ka-Moretti kanye Nekusasa Locwaningo Lwebhizinisi

Emhlabeni wezomnotho wezemfundo, ambalwa amajenali anesisindo se-American Economic Review (AER). Lapho ishicilela ucwaningo lokuphindaphinda kwephepha eliyingqopha-mlando, yonke inkambu iyaqaphela. Lokhu yikho kanye okwenzekile ngokuphindaphinda kwakamuva, okulindeleke kakhulu komsebenzi ka-Enrico Moretti wokuphindaphinda kwezenhlalo yabantu kanye nezwe lokusungula izinto ezintsha. Kumabhizinisi nabahlaziyi, lo mcimbi ungaphezu kombhalo waphansi wezemfundo; kuyisifundo esinamandla sokuqina, ukuqinisekiswa, kanye nokubaluleka okubalulekile kokwakha izinqumo esisekelweni sedatha eqinile, eqinisekiswayo. Enkathini lapho ukukhetha kwamasu kuqhutshwa ngamandla edatha, izimiso ezigcizelelwa yilokhu kuphindaphinda zisebenza ngokuqondile ekutheni izinkampani zesimanje, mhlawumbe zisebenzisa i-OS yebhizinisi elifana ne-Mewayz, kufanele zibhekane nobuhlakani bazo bokusebenza.

Ukuqonda Ucwaningo Lwangempela lwe-Moretti

Ucwaningo lwangempela luka-Enrico Moretti, "I-Social Return to Education and Human Capital," luhlole into ethokozisayo: ukugxila kokusungula izinto ezintsha kanye nokukhiqiza emadolobheni athile. UMoretti wagomela ngokuthi izinzuzo zabasebenzi abafundile kakhulu zidlulela ngaphezu komholo ngamunye. Ubeke umphumela "wokuphindaphinda kwezenhlalo", lapho ukuba khona kwabasebenzi abanamakhono eqenjini (njenge-Silicon Valley) kudala izinzuzo ze-spillover—ukuqamba okusha, amaholo aphezulu abo bonke abantu, kanye neminotho yasendaweni eqinile—engabanjwa yimbuyiselo yangasese iyodwa. Lo msebenzi ube nomthelela omkhulu ekucabangeni kwezomnotho wasemadolobheni, isu lethalente, kanye nokutshalwa kwezimali komphakathi kwezemfundo, okusikisela ukuthi "indawo yemisebenzi" yayixhumene ngokujulile nesizinda somnotho wabantu.

Ukuphindaphinda kwe-AER: Lokho Ekutholile nokuthi Kungani Kubalulekile

Ucwaningo lokuphindaphinda, oluholwa ithimba labacwaningi abazimele, lenze umsebenzi onzima wokwakha kabusha ukuhlaziya kuka-Moretti kusukela phansi kuya phezulu. Umgomo wabo kwakungekona ukudelela kodwa ukuqinisekisa, isisekelo sendlela yesayensi evame ukubhekwa kancane ezimweni zebhizinisi nenqubomgomo ezihamba ngokushesha. Okutholakele bekunama-nuances kodwa kubalulekile. Nakuba isiphetho esiyinhloko—sokuthi izinto zangaphandle zenani labantu zikhona—zimisiwe, isilinganiso sobukhulu sokuphindaphindeka komphakathi sitholakale sizwela ekukhetheni okuthile kwendlela yokusebenza nezincazelo zedatha. Ukuphindaphinda kuqinisekise ukuqonda kokuqondisa kodwa kwalungisa ukunemba kobuningi, kunikeze ukuqonda okulinganiselwe kakhudlwana kwamandla omphumela. Le nqubo igqamisa iqiniso elitholakala emhlabeni wonke: okutholwe ekuqaleni kunikeza imephu, kodwa ukuphindaphinda kuqinisekisa ukuthi indawo ihlelwe ngokunembile.

"Ukuphindaphinda kuyisisekelo solwazi lwesayensi oluqoqiwe. Kuhlukanisa imininingwane eqinile, engajwayelekile naleyo engase ibe ntekenteke noma iqonde ngqo komongo. Kwezomnotho nasebhizinisini, lokhu kuziphatha yikho okuguqula amaphethini athakazelisayo abe izisekelo ezithembekile zesenzo."

Izifundo Zebhizinisi Eliqhutshwa Idatha

Ukuphindaphinda kwe-Moretti kunikeza izinto ezimbalwa ezibalulekile okufanele zithathwe kunoma iyiphi inhlangano ethembele ekuhlaziyweni kwedatha ukuze iqondise amasu, kusukela ocwaningweni lwemakethe namamethrikhi okusebenza kuya ekubikezelweni kwezimali nokuphathwa kwethalente.

• Ukubonisa ngale Akuxoxiswana: Ikhono lokuphindaphinda okutholiwe lincike ekubhalweni okucacile kwemithombo yedatha, izinyathelo zokuhlanza, namamodeli okuhlaziya. Amabhizinisi kufanele asebenzise leli zinga elifanayo lokubika kwangaphakathi.
• Embrace Methodological Scrutiny: Imiphumela ebalulekile kufanele ihlolwe ingcindezi kusetshenziswa ukuqagela okuhlukile noma amamodeli. Ingabe isiphetho sakho mayelana nemakethe eqondiwe singashintsha uma usichaza ngokwehlukile ingxenye? Ukuhlola ukuqina kubalulekile.
• Ukuqinisekiswa Kwenani Ngaphezu Kwesivinini: Nakuba isivinini sokuqonda sincintisana, ukunemba kubaluleke kakhulu. Ukwakha isiko elima ukuze kuqinisekiswe idatha ebalulekile kuvimbela amasu angalungile abizayo.
• Izindaba Zokuqukethwe: Ukuphindaphinda kusikhumbuza ukuthi amasayizi omthelela angahluka. Isu elisebenze emakethe yesifunda eyodwa kungenzeka lingalingani namandla afanayo kwenye indawo; ubuhlakani bendawo bubalulekile.

Ukwakha Ukugeleza Kokusebenza Okulungele Ukuphindaphinda nge-Mewayz

Lapha yilapho inkundla yokusebenza yesimanje iba semqoka khona. I-OS yebhizinisi eyimodular efana ne-Mewayz yakhelwe ukwenza imigomo yokubeka izinto obala nokuqinisekiswa ibe isikhungo. Ngokuhlanganisa ukusakazwa kwedatha, ukwenza izindlela zokucwaninga ngokuzenzakalelayo, kanye nokubhala izinqubo zokuhlaziya ngaphakathi kwamamojula ayo, i-Mewayz idala indawo "elungele ukuphindaphinda". Ukuthi ithimba labadayisi lihlaziya ukuguqulwa kwamapayipi noma ubuholi bumodela izimo zokunwetshwa, inkundla iqinisekisa ukuthi yonke imininingwane ingalandelelwa emuva emthonjeni wayo nendlela yayo. Lokhu akukubambezeli ukuthatha izinqumo; kuyayiqinisa. Njengoba nje ukuphindaphinda kwe-AER kuqinise ukuqonda kwenkambu yendawo yezomnotho, ukuhlanganisa ukuqinisekiswa ku-OS yebhizinisi lakho kwakha inhlangano enamandla, eqinile. Ekugcineni, umgomo uyafana: ukuguqula idatha isuke ekubonweni kwephuzu lesikhathi ibe yimpahla ekwazi ukukhiqizwa kabusha, ethembekile yokukhula kwesikhathi eside.
