A bibliometric analysis of the Bacillus anthracis and Ebola virus archival literature was conducted to determine whether negative consequences of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism" (USA PATRIOT) Act and the 2002 Bioterrorism Preparedness Act on US select agent research could be discerned. Indicators of the health of the field, such as number of papers published per year, number of researchers authoring papers, and influx rate of new authors, indicated an overall stimulus to the field after 2002. As measured by interorganizational coauthorships, both B. anthracis and Ebola virus research networks expanded after 2002 in terms of the number of organizations and the degree of collaboration. Coauthorship between US and non US scientists also grew for Ebola virus but contracted for the subset of B. anthracis research that did not involve possession of viable, virulent bacteria. Some non-US institutions were dropped, and collaborations with others intensified. Contrary to expectations, research did not become centralized around a few gatekeeper institutions. Two negative effects were detected. There was an increased turnover rate of authors in the select agent community that was not observed in the control organism (Klebsiella pneumoniae) research community. However, the most striking effect observed was not associated with individual authors or institutions; it was a loss of efficiency, with an approximate 2- to 5-fold increase in the cost of doing select agent research as measured by the number of research papers published per millions of US research dollars awarded.
对炭疽芽孢杆菌和埃博拉病毒的存档文献进行了文献计量分析,以确定《通过提供拦截和阻止恐怖主义所需的适当工具来团结和加强美国》(《美国爱国者法案》)以及2002年《生物恐怖主义防范法案》对美国特定病原体研究的负面影响是否可以识别。该领域健康状况的指标,如每年发表的论文数量、撰写论文的研究人员数量以及新作者的流入率,表明2002年后该领域受到了总体刺激。通过组织间共同作者关系衡量,炭疽芽孢杆菌和埃博拉病毒的研究网络在2002年后在组织数量和合作程度方面都有所扩大。美国和非美国科学家之间关于埃博拉病毒的共同作者关系也有所增加,但在不涉及拥有活的、有毒力细菌的炭疽芽孢杆菌研究子集中却有所减少。一些非美国机构退出了,与其他机构的合作则加强了。与预期相反,研究并没有集中在少数把关机构周围。检测到了两个负面影响。在特定病原体研究领域,作者的更替率有所增加,而在对照生物体(肺炎克雷伯菌)研究领域则未观察到这种情况。然而,观察到的最显著影响并非与个别作者或机构相关;而是效率的损失,以每百万美元美国研究经费所发表的研究论文数量来衡量,进行特定病原体研究的成本大约增加了2至5倍。
