Isbeddelka ah in ragga ay qaataan khataro ka badan kuwa dumarka marka la barbar dhigo giraangiraha ayaa u muuqda mid laga soo baxay, sida laga soo xigtay daraasad cusub oo badbaadada waddooyinka oo ay samaysay shirkadda Goodyear ee soo saarta taayirka.
Sahankan ayaa diiradda lagu saaray hab-dhaqanka waalidiinta aan khibradda u lahayn darawallada ee ku aaddan badbaadada waddooyinka. Daraasada ayaa muujisay in darawaliinta Yurub, aabayaasha Turkiga iyo Romania ay u badan tahay in lagu ciqaabo xawaaraha xawaaraha marka loo eego hooyooyinka. Romania, 29% aabayaasha ayaa lagu qabtay xawaare sare marka la barbardhigo 7% hooyooyinka. Tiradu waxay la mid tahay Turkiga (28% aabayaasha marka loo eego 6% hooyooyinka).
Wadamada Austria, Finland, Denmark iyo Russia, waalidiinta dhalay darawalada da'da yar ee aan khibrada u lahayn darawalnimada ayaa laba jeer ka badan in lagu ciqaabo xawaaraha xawaaraha sida hooyooyinka. Celcelis ahaan Midowga Yurub (EU) waa 24% ragga marka loo eego 18% dumarka[1].
Si ka duwan habkan, darawalada dumarka Belgian ayaa aad uga halis badan ragga. Ku dhawaad saddex meelood meel meel dumarka Belgian (30%) ee la waraystay waxay qirteen inay xawli ku socdaan marka la barbar dhigo 28% ragga.
Cilmi-baadhista Goodyear waxay ku salaysan tahay sahan dhammaystiran oo lagu sameeyay in ka badan 6,800 oo waalid oo aan khibrad u lahayn darawallada (da'doodu tahay 16-25) ee 19 waddan. Cilmi-baadhistan ayaa ujeedadeedu ahayd in si fiican loo fahmo hab-dhaqannada waaliddiinta ee ku aaddan badbaadada waddooyinka, haddii ay ahaan lahayd tusaale ahaan darawalnimada, iyo sidoo kale sida ay u taageeraan carruurtooda ee baranaya wadista baabuurta.
Marka loo eego sahamintii hore ee Goodyear ee darawallada iyo macallimiinta aan khibradda lahayn, ragga da'da yar waxay sidoo kale aad ugu dhow yihiin dumarka da'da yar (70% vs. 62%). Macallimiinta darawalnimada waxay u muuqdaan inay ka warqabaan dhaqankan, iyo badi macallimiinta EU (52%) waxay isku raaceen in dhaqanka reer galbeedka uu ammaano wadista degdega ah taasoo calaamad u ah ragganimada.
Dumarku way ka kalsooni yar yihiin ragga waddada ku jira
Waxaa jira kala duwanaansho weyn oo u dhexeeya lab iyo dheddig marka ay timaado dayactirka taayirka: 20% haweenku kuma kalsoona inay beddelaan taayirka fidsan marka loo eego 2% ragga. Iyadoo tan qayb ahaan lagu sharxi karo kala duwanaanshiyaha xagga awoodaha jireed, waxaa sidoo kale jirta suurtogalnimo weyn in raggu aad ugu kalsoon yihiin wadista baabuurta xaaladaha cimilada xun (24% vs. 13%).
Xogta cusub ee Goodyear ee ku saabsan hab-dhaqanka waalidka iyo hab-dhaqanka badbaadada waddooyinka ayaa ku salaysan shaqooyin la qabtay sannadihii hore, kuwaas oo daboolay hab-dhaqanka dhalinyarada ee ku wajahan baabuur-wadidda iyo badbaadada waddooyinka (2012) iyo kuwa macallimiinta badbaadada waddooyinka. Driving (2013), daraasad lagu sameeyay ku lug lahaa dhowr xarumood oo ku xidhan ifafaalaha baabuurta iyo wadista baabuurta.
