Biologul britanic Sholto David i-a acuzat pe cercet\u0103torii de la prestigiosul Institut de Cancer Dana-Farber (DFCI), afiliat la Harvard Medical School, c\u0103 au manipulat imagini \u0219i date \u00een studiile lor publicate. Acuza\u021biile lui David, postate pe blogul independent For Better Science, includ exemple de benzi proteice, grafice de date \u0219i rezultate PCR despre care sus\u021bine c\u0103 au fost modificate cu ajutorul func\u021biilor de copiere-lipire sau al programului Photoshop.<\/p>\n\n
\u00cen urma afirma\u021biilor lui David, DFCI a lansat o revizuire intern\u0103 a cercet\u0103rii \u00een cauz\u0103. Drept urmare, institutul a anun\u021bat c\u0103 va retrage cel pu\u021bin \u0219ase studii \u0219i va corecta \u00eenc\u0103 31. Studiile afectate au fost publicate \u00een reviste medicale \u0219i biologice importante, precum Molecular and Cellular Biology, Clinical Cancer Research \u0219i Blood.<\/p>\n\n
Multe dintre studiile analizate au fost publicate de oamenii de \u0219tiin\u021b\u0103 de top ai DFCI, inclusiv pre\u0219edinta \u0219i CEO Laurie Glimcher, directorul de opera\u021biuni William Hahn \u0219i cercet\u0103torii seniori Irene Ghobrial \u0219i Kenneth Anderson. Acuza\u021biile au ridicat \u00eengrijor\u0103ri cu privire la procesul de revizuire intern\u0103 al institutului \u0219i la integritatea cercet\u0103rii sale.<\/p>\n\n
David a folosit at\u00e2t ochiul liber, c\u00e2t \u0219i software-ul de inteligen\u021b\u0103 artificial\u0103 numit ImageTwin pentru a detecta presupusa manipulare a imaginilor. Software-ul este conceput s\u0103 identifice similarit\u0103\u021bi \u0219i discrepan\u021be \u00een imagini, ajut\u00e2nd la descoperirea poten\u021bialelor modific\u0103ri.<\/p>\n\n
Acuza\u021biile \u00eempotriva DFCI au atras o aten\u021bie semnificativ\u0103 din partea comunit\u0103\u021bii \u0219tiin\u021bifice \u0219i a mass-media. The New York Times, Wall Street Journal \u0219i Harvard Crimson au relatat cu to\u021bii povestea, subliniind implica\u021biile pentru integritatea cercet\u0103rii.<\/p>\n\n
Unii cercet\u0103tori au r\u0103spuns rapid acuza\u021biilor. Hahn \u0219i Ghobrial au trimis revistelor imagini corectate pentru studiile men\u021bionate de David. Al\u021bii au ap\u0103rat integritatea cercet\u0103rii lor, subliniind complexitatea datelor \u0219tiin\u021bifice \u0219i posibilitatea unor erori neinten\u021bionate.<\/p>\n\n
Acuza\u021biile \u00eempotriva DFCI ridic\u0103 \u00eentreb\u0103ri importante cu privire la conduita \u0219tiin\u021bific\u0103 necorespunz\u0103toare. Exper\u021bii \u00een integritatea cercet\u0103rii au subliniat c\u0103 prezen\u021ba discrepan\u021belor \u00een imagini nu indic\u0103 neap\u0103rat o inten\u021bie de a induce \u00een eroare. Cu toate acestea, este necesar\u0103 o investiga\u021bie atent\u0103 pentru a determina dac\u0103 a avut loc vreo fapt\u0103 gre\u0219it\u0103.<\/p>\n\n
Conduita \u0219tiin\u021bific\u0103 necorespunz\u0103toare poate avea consecin\u021be grave, inclusiv retr\u0103geri, pierderea reputa\u021biei \u0219i prejudicierea credibilit\u0103\u021bii comunit\u0103\u021bii \u0219tiin\u021bifice. Este esen\u021bial ca cercet\u0103torii s\u0103 respecte standardele etice \u0219i s\u0103 asigure acurate\u021bea \u0219i integritatea muncii lor.<\/p>\n\n
Rolul lui David ca avertizor de integritate a jucat un rol semnificativ \u00een aducerea la lumin\u0103 a acestor acuza\u021bii. Avertizorii de integritate se confrunt\u0103 adesea cu provoc\u0103ri \u0219i riscuri atunci c\u00e2nd raporteaz\u0103 o conduit\u0103 necorespunz\u0103toare, dar ac\u021biunile lor pot contribui la protejarea integrit\u0103\u021bii cercet\u0103rii \u0219i a \u00eencrederii publicului \u00een \u0219tiin\u021b\u0103.<\/p>\n\n
Acuza\u021biile \u00eempotriva DFCI au determinat solicit\u0103ri pentru o revizuire am\u0103nun\u021bit\u0103 a practicilor de cercetare ale institutului. Exper\u021bii subliniaz\u0103 necesitatea unor procese interne solide de revizuire \u0219i a unor mecanisme eficiente pentru detectarea \u0219i abordarea poten\u021bialelor conduite necorespunz\u0103toare.<\/p>\n\n
Comunitatea \u0219tiin\u021bific\u0103 trebuie s\u0103 colaboreze, de asemenea, pentru a promova o cultur\u0103 a integrit\u0103\u021bii \u00een cercetare, \u00een care cercet\u0103torii sunt \u00eencuraja\u021bi s\u0103 raporteze preocup\u0103rile \u0219i \u00een care avertizorii de integritate sunt proteja\u021bi. Prin promovarea unui mediu de cercetare transparent \u0219i etic, putem contribui la asigurarea fiabilit\u0103\u021bii \u0219i credibilit\u0103\u021bii cuno\u0219tin\u021belor \u0219tiin\u021bifice.<\/p>","protected":false},"excerpt":{"rendered":"
