Ukuhlaziywa kwe-Meta kuwukuhlanganisa nokuhlanganisa izifundo ezihlukahlukene ezivele zikhona esihlokweni esinikeziwe. Kuyasiza ukuqinisa nokucacisa iziphetho ezithathwe ezifundweni ezihlukahlukene.

Ukuhlaziywa kwe-Meta kuyindlela yokuhlanganiswa kwemiphumela yezifundo ocwaningweni lwezokwelapha. Kudinga umsebenzi omkhulu wokuhlanganisa nokuhlanganiswa kwedatha evela ezifundweni ezahlukene esihlokweni esithile. Iphendula endleleni eqondile, kokubili yokusesha, ukukhetha, ukwethulwa kanye nokuhlaziywa kwezifundo ezitholakalayo zombuzo othile. Kungumsebenzi oyinkimbinkimbi futhi omkhulu ngoba ulwazi lwezokwelapha namuhla lutholakala kalula futhi luningi kakhulu. Ukuhlaziywa kwe-meta kusekelwe kuphrothokholi enembile, ethembekile futhi ekwazi ukukhiqizwa kabusha, ngakho imiphumela ihlala ifana kungakhathaliseki ukuthi umbhali wokuhlaziya.

Inhloso yokuhlaziywa kwe-meta ukuhlanganisa inani elikhulu lolwazi ngesihloko esinikeziwe. Lokhu kwandisa amathuba okuthola umphumela obalulekile ngokwezibalo, okungukuthi umphumela onokwethenjelwa, ofakazela kahle okunikeziwe. Lokhu kubizwa ngokuthi ukwanda kwamandla ezibalo.

Ngokushesha nje lapho kunezifundo ezimbalwa ezenze ukuphendula umbuzo ofanayo njengenhloso eyinhloko noma yesibili, ukuhlaziywa kwe-meta kuyenzeka. Kuyindlela ebalulekile yokwenza lezi zifundo. Kwenza kube nokwenzeka ukunikeza impendulo enembayo nephelele ngokuhambisana nalo lonke ulwazi lwamanje. Umkhakha wokufaka isicelo ukhawulelwe kuphela kuleso sezifundo ezivele zikhona. Indawo yokuqala yohlelo lokusebenza ukuhlola ukusebenza kahle nemiphumela engemihle yokwelashwa kwezidakamizwa. Ukuhlaziywa kwe-Meta kungase futhi kube usizo kakhulu kwezinye izindawo ezifana ne-epidemiology, ukuphathwa kwezokwelapha, ukunakekelwa ngokuvamile, ukuhlolwa noma ukuxilongwa.

Ukuhlaziywa kwe-Meta kuyindlela esetshenziswa kabanzi kuyo yonke imikhakha yocwaningo lwe-biomedical ukuze kuchazwe kabanzi izifundo eziningi nezihlukahlukene, ngezinye izikhathi eziphikisanayo. Ibuye isetshenziswe imiphakathi efundile emkhakheni wezokwelapha ukusungula izincomo zokunakekelwa nokwelashwa kweziguli ngokusekelwe ezingeni eliphezulu lobufakazi. I-meta-analyses yokuqala ihlehlela emuva kuma-70s futhi inombolo yabo ibilokhu ikhula kusukela lapho ngoba intshisekelo yabo ayinakuphikwa.

Esimeni socwaningo ngomuthi, ukuhlaziya imeta kungasiza ukukala ukusebenza kahle nokubekezelelana kwalesi. Ngempela, ukuhlanganiswa kwezifundo zemitholampilo ehlukene ngayinye ehlanganisa inombolo encane yeziguli kwenza kube nokwenzeka ukwandisa le nombolo ukuze ukubhekwa kubaluleke ngokwezibalo. Ukuhlaziywa kwe-meta kungabese kugqamisa umphumela wokwelashwa lapho izinhlolo ezincane zingaholeli esiphethweni. Uhlolo lomtholampilo olukhulu lunzima kakhulu ukulwenza ngokwenza. Ukuhlaziywa kwe-Meta kwenza kube nokwenzeka ukunqoba lobu bunzima.

Kungasiza futhi ukunquma, ngendlela eyodwa noma enye, lapho imiphumela iphikisana. Uhlangothi lwayo olufingqiwe futhi lwenza kube nokwenzeka ukuqoqa idatha ukuze kutholwe impendulo enembile yombuzo othile. Lokhu kuwusizo ikakhulukazi ezindaweni zocwaningo lapho idatha iqoqwa khona.

Kwezokwelapha, ukwenza ukuhlaziya imeta, umcwaningi uchaza isihloko esithakaselwayo. Kungaba ukwelashwa okufanele kuhlolwe, uhlobo lwesiguli esihlolwe, idatha ye-epidemiological, imiqondo yokunakekelwa, njll.

Isinyathelo sesibili ukuchaza indlela yokufaka ekuhlaziyweni kwe-meta oyifunayo. Umcwaningi uyobe esebheka izinhlolo nezifundo ezihlukahlukene, ezishicilelwe noma cha, ezitholakala ezincwadini zezokwelapha. Lezi zinto zingaba ama-athikili, amaphosta, amaphepha avela ezingqungqutheleni zezokwelapha, izingqikithi zabafundi, izivivinyo zomtholampilo, njll. Zikhethwa uma zihlangabezana nemibandela yokufakwa kuhlaziyo lwemeta. Umqondo uwukuhlanganisa ndawonye izifundo eziningi ngangokunokwenzeka ekuhlaziyweni kwe-meta ukuze kunikezwe inani eliningi namandla ngangokunokwenzeka.

Kube sekusetshenziswa izindlela zokuhlaziya izibalo. Ukuhlaziya ngeqembu elincane (ubulili, ubudala, umlando wezokwelapha, uhlobo lwesifo, njll.) kungenziwa. Ngokuvamile, abacwaningi abaningana bawela ukufundwa kwabo ukuze banikeze isisindo esiningi ekuhlaziyeni.

Ukuhlaziywa kwe-meta kwenza kube nokwenzeka ukukhiqiza idatha entsha enesisindo esengeziwe ngokwezibalo ngoba ziningi noma ziqoqela ndawonye iziguli eziningi. Ngokuhambisana nendlela yesayensi, abacwaningi bazohumusha imiphumela yokuhlaziywa kwe-meta futhi bayibeke kumongo wabo. Inhloso wukuthola iziphetho ngedatha eqoqiwe. Lokhu kungenelela komcwaningi kuzoholela ekuziphatheni. Impela kuzongena isipiliyoni sayo nesiko layo. Kusukela kudatha yenhloso ngokuphelele, ngakho-ke kungenzeka ukuthi abacwaningi abahlukene bathole iziphetho ezahlukene.
