Managing at the Speed of Light: Improving Mission-Support Performance

The House and Senate Energy and Water Development Appropriations Subcommittees requested this study to help DOE's three major mission-support organizations improve their operations to better meet the current and future needs of the department. The passage of the Recovery Act only increased the importance of having DOE's mission-support offices working in the most effective, efficient, and timely manner as possible. While following rules and regulations is essential, the foremost task of the mission-support offices is to support the department's mission, i.e., the programs that DOE is implementing, whether in Washington D.C. or in the field. As a result, the Panel offered specific recommendations to strengthen the mission-focus and improve the management of each of the following support functions based on five "management mandates":- Strategic Vision- Leadership- Mission and Customer Service Orientation- Tactical Implementation- Agility/AdaptabilityKey FindingsThe Panel made several recommendations in each of the functional areas examined and some overarching recommendations for the corporate management of the mission-support offices that they believed would result in significant improvements to DOE's mission-support operations. The Panel believed that adopting these recommendations will not only make DOE a better functioning organization, but that most of them are essential if DOE is to put its very large allocation of Recovery Act funding to its intended uses as quickly as possible

Reliability and validity of cross-national homicide data: A comparison of UN and WHO data

Data reliability and validity are major methodological concerns in cross-national analyses of crime. Despite the large literature on cross-national homicide rates, there is little agreement on which source of data provides the most reliable estimates. In addition, few studies have examined the potential threat to validity posed by unclassified deaths. Through a description of trends over time as well as multivariate analyses, the current study aims to shed some light on these questions by (1) assessing the reliability of cross-national homicide data from the United Nations and the World Health Organization, and (2) investigating the impact of unclassified deaths on the validity of WHO data. Findings indicate that UN and WHO homicide rates (n=56) differ in magnitude but produce similar outcomes. Drawing on well-known correlates of cross-national homicide rates, the UN data provide more robust results and produce statistical models with less error. We find that WHO data are more stable and reliable over time, and better suited for longitudinal analyses. Findings also suggest that analyses drawing on WHO homicide data should not disregard unclassified deaths because their inclusion produces better fitted statistical models and provides a closer estimate of the true number of homicides

A somatic coliphage threshold approach to improve the management of activated sludge wastewater treatment plant effluents in resource-limited regions

Versión aceptada para publicaciónEffective wastewater management is crucial to ensure the safety of water reuse projects and 29 effluent discharge into surface waters. Multiple studies have demonstrated that municipal 30 wastewater treatment with conventional activated sludge processes is inefficient for the removal 31 of the wide spectrum of viruses in sewage. In this study, a well-accepted statistical approach was 32 used to investigate the relationship between viral indicators and human enteric viruses during 33 wastewater treatment in a resource-limited region. Influent and effluent samples from five urban 34 wastewater treatment plants (WWTP) in Costa Rica were analyzed for somatic coliphage and 35 human enterovirus, hepatitis A virus, norovirus genotype I and II, and rotavirus. All WWTP 36 provide primary treatment followed by conventional activated sludge treatment prior to 37 discharge into surface waters that are indirectly used for agricultural irrigation. The results 38 revealed a statistically significant relationship between the detection of at least one of the five 39 human enteric viruses and somatic coliphage. Multiple logistic regression and Receiver Operating Characteristic curve analysis identified a threshold of 3.0 ×103 40 (3.5-log10) somatic 41 coliphage plaque forming unit per 100 mL, which corresponded to an increased likelihood of encountering enteric viruses above the limit of detection (>1.83×102 42 virus target/100 mL). 43 Additionally, quantitative microbial risk assessment was executed for famers indirectly reusing 44 WWTP effluent that met the proposed threshold. The resulting estimated median cumulative 45 annual disease burden complied with World Health Organization recommendations. Future 46 studies are needed to validate the proposed threshold for use in Costa Rica and other regions.Universidad de Costa Rica/[]/UCR/Costa RicaNational Science Foundation/[OCE-1566562]/NSF/Estados UnidosUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias de la Salud::Instituto de Investigaciones en Salud (INISA)UCR::Vicerrectoría de Docencia::Salud::Facultad de Microbiologí
