Comparing Electronic News Media Reports of Potential Bioterrorism-Related Incidents Involving Unknown White Powder to Reports Received by the United States Centers for Disease Control and Prevention and the Federal Bureau of Investigation: U.S.A., 2009–2011 下载免费PDF全文
Geroncio C. Fajardo M.D. M.B.A. M.S. M.S. Joseph Posid M.P.H. Stephen Papagiotas M.P.H. Luis Lowe M.S. M.P.H. 《Journal of forensic sciences》2015,60(Z1):S76-S82
There have been periodic electronic news media reports of potential bioterrorism-related incidents involving unknown substances (often referred to as “white powder”) since the 2001 intentional dissemination of Bacillus anthracis through the U.S. Postal System. This study reviewed the number of unknown “white powder” incidents reported online by the electronic news media and compared them with unknown “white powder” incidents reported to the U.S. Centers for Disease Control and Prevention (CDC) and the U.S. Federal Bureau of Investigation (FBI) during a 2-year period from June 1, 2009 and May 31, 2011. Results identified 297 electronic news media reports, 538 CDC reports, and 384 FBI reports of unknown “white powder.” This study showed different unknown “white powder” incidents captured by each of the three sources. However, the authors could not determine the public health implications of this discordance. 相似文献

ABSTRACT Our ability to interpret, generalize, and build theory across public service motivation (PSM) studies is limited by lack of knowledge regarding the equivalence of different PSM measures that researchers frequently use. While past research has given considerable attention to validating multidimensional measures of PSM, this study investigates the psychometric properties of the global measures that have been used to provide much of the empirical evidence on PSM. Building on the lessons of other research using global and multidimensional measures, we first discuss the strengths and weaknesses of existing global measures of PSM relative to those of the multidimensional measures. After highlighting the potential merit of global scales, we then provide empirical justification for global scales. Using five different data sets to compare commonly used global measures of PSM, our findings suggest that these different measures are not only highly correlated with each other but also display a similar pattern and strength of relationships with important correlates of PSM. These findings suggest that these measures do tap into the same conceptual space and help validate our continued reliance on empirical studies that have used different measures to build our understanding of PSM. 相似文献
