Voelz et al. conducted a study of 7,112 white male workers employed at Rocky Flats between 1952 and 1979. Deaths in workers were compared with those in the U.S. white male population. Fewer deaths were observed than expected based on rates in the U.S. population from most causes. The only cause of death significantly elevated in these workers was brain cancers. There were eight deaths in the Ro...

Based upon the identification of 38 white dwarfs with halo kinematics, in a survey covering 10% of the sky near the south Galactic pole, Oppenheimer et al. (1) argue that at least 2% of the dark matter in the Galaxy has now been detected directly. Put into context, the Oppenheimer et al. result implies that the stellar remnant mass of the halo may be comparable to that of the entire disk of our...

White Spot Syndrome Virus (WSSV) is a double-stranded (305 kb) DNA invertebrate virus (Wang et al 1998) that causes White Spot Syndrome (WSS) in almost all commercially available crustaceans. Though 22 different viruses are known to cause diseases in shrimp (Hsu et al 2000), WSSV is particularly of great interest to cause mass mortality in 3-10 days of disease blitz. The estimated annual global...

1.1 Breast cancer classification Breast cancer is one of the most common cancers among women worldwide and approximately one-third of women diagnosed will eventually develop metastases and die (Jemal et al, 2010). Breast cancer is heterogeneous at the molecular, histopathologic and clinical levels and is commonly classified into several categories according to multiple schemes, each based on di...

The examination of a student’s racial identity beliefs along with the extent to which being Black is a central part of his or her self-concept provides a novel, insightful approach to understanding the relationship between racial identity and academic achievement (Chavous et al., 2003,). Using Sellers et al. (1998a) Multi-dimensional Model of Black Identity (MMBI) as a framework, this study inv...

This paper compares two influential attempts at presenting a comprehensive framework of knowledge management. For each perspective the author examines theoretical foundations, highlights conceptual elements and themes, and discusses the role of information and information management. Ikujiro Nonaka and Hirotaka Takeuchi analyze the dynamics of knowledge creation, particularly the importance of ...
