Ukuhlaziywa kwemvelo kuyindlela yokuba ososayensi babheke impikiswano emikhulu yezinhlelo ezithile ezithintekayo ezempilo yabantu. Kulezi zinhlobo zezifundo, abacwaningi bahlola impilo yabantu ngaphambi nangemva komcimbi othize. Isibonelo, ukuhlaziywa kwemvelo kuvame ukuqhutshwa kwidatha eqoqwe ngaphambi nangemva kokusungulwa kohlelo lokugoma kazwelonke.
Kungenziwa futhi emva kokunye ukungenelela kwezempilo emphakathini omkhulu.
Ukuhlaziywa kwemvelo kubheka impilo yabantu, hhayi abantu ngabanye. Zisekelwe kwizibalo zabantu futhi azicabangi ngokujwayelekile isimo sokungenelela esithile ngabanye. Ngakho-ke, isifundo sezinto eziphilayo esibheka amazinga ajwayelekile eP Pap smear ngaphambi nangemva kokuhlelwa kohlelo lokugoma lonke lwe- HPV angeke kubheke ukuthi ngabe umuntu othile uphonywe yini. Esikhundleni salokho, bekuzobheka nje ukusabalalisa kwemiphumela engavamile eminyakeni ngaphambi kokuba ngemuva kokugoma.
Nakuba ukuhlaziywa kwemvelo kungaba usizo kakhulu ekubhekeni impembelelo yokungenelela okukhulu, kunqunyelwe ukuthi abakwazi ukubheka imbangela nomphumela kubantu ngabanye. Kubalulekile ukucabangela lokhu lapho uhumusha imiphumela yabo.
Ukuhlaziywa kwemvelo akugcini ekucwaningeni imiphumela yokungenelela kwempilo.
Zingasetshenziswa futhi ukuhlaziya umthelela wezinguquko zezombusazwe noma ezemvelo nezinhlekelele zemvelo ezempilo noma ukuhlola imiphumela engeyona yezempilo. Okuwukuphela kwendlela echaza ngayo ukuhlaziywa kwemvelo ukuthi i-unit of analysis iyabantu, hhayi umuntu.
Futhi eyaziwa ngokuthi: isifundo sezemvelo
Izibonelo
Ucwaningo lwezinto eziphilayo luye lwasetshenziselwa ukuphikisa ukuxhumana okuhlongozwayo phakathi kwe-autism kanye nokugonywa kwe-MMR. Lapho abacwaningi behlola amazinga we-autism ngaphambi nangemva kokuqaliswa kwezinhlelo zokugoma (noma ngaphambi nangemva kokugonywa okusetshenziselwa ukuguqulwa) baye babona ukungalingani phakathi kwe-autism nokugoma. Esikhundleni salokho, kubonakala sengathi ama-autism amazinga aye ekhuphuka kancane ngokuhamba kwesikhathi - mhlawumbe ngenxa yezinguquko ekucutshungeni kanye / noma izici ezingavumelekile zendawo.
Esinye isibonelo sokuhlaziywa kwemvelo yilokho okukhulunywe ngenhla - ukuhlola umphumela wokugoma kwe- HPV ku- Pap smear engavamile, noma umdlavuza wesibeletho , amazinga. Ucwaningo oluthile lwenzile lokho, emazweni anokutholwa okukhulu kwe-HPV yokugonywa okuye kwabonakala e-United States. Ukucwaninga eNetherlands, eNgilandi nase-Australia kuye kwabonisa ukuthi kunciphisa ama-warts omzimba kanye nezinguquko zangaphambi komdlavuza wesibeletho.
