Beyond Dichotomy: Dwight Waldo and the Intertwined Politics–Administration Relationship

Dwight Waldo's conception of the politics–administration question might be better understood as a "relationship" that contains elements of separation and intermixture rather than a "dichotomy," according to this author-commentator.To suggest that Waldo came to support the dichotomy presumes agreement about the meaning of the concept that is missing in Waldo's writings and in the public administration literature.     

Characterization of human DNA in environmental samples

Environmental samples from indoor surfaces can be confounded by dust, which is composed largely of human skin cells and has been documented to contain roughly tens of micrograms of total DNA per gram of dust. This study complements previous published work by providing estimates of the quantity of amplifiable human DNA found in environmental samples from a typical indoor environment, categorized by the intensity of human traffic and visible quantity of dust. Dust was collected by surface swabbing standard 576 cm² areas in eight locations, and evaluated for total DNA quantity, presence of human DNA (mitochondrial and nuclear loci using conventional PCR), quantity of human nuclear DNA using quantitative PCR, and STR analysis. The total DNA content of 36 dust samples ranged from 9 to 28 ng/cm², and contained 0.2–1.1 pg/cm² of human DNA. Overall, human DNA was detected in 97% of 36 dust samples and 61% of samples yielded allele distributions of varying degrees of complexity when subjected to STR analysis. The implications of this study are twofold. First, the presence of dust in evidence can be a significant contamination source in forensic investigations because the human DNA component is of sufficient quality and quantity to produce allele calls in STR analysis. This can be effectively managed by implementing stringent protocols for collection and analysis of potential biological samples. A second implication is the use of dust as a source of evidence for identification of inhabitants within a defined location. In the latter case, a number of additional studies would be necessary to identify relevant pretreatments for environmental dust samples and to develop the necessary deconvolution techniques to separate the composite genotypes obtained.     

Student Success and Failure in a Graduate Criminology/Criminal Justice Program

Despite the burdens that students and institutions assume when underwriting educational careers, very little is known about completion rates, risk factors, and successful strategies of criminology/criminal justice (CCJ) graduate programs. Consequently, the present study tracks 287 master’s and 70 doctoral students who entered the Florida State University CCJ program during the 1991–2000 academic years. Almost two-thirds of this cohort earned an advanced degree. Younger students with higher GRE scores were more likely to complete the master’s program. Successful doctoral degree recipients tended to have lower GRE scores, be non-White, and earn their master’s degrees in-house. In terms of time-to-degree, it took over two years to earn an M.A. and slightly more than six years to negotiate the Ph.D. Implications are explored for the program, the university, and the discipline.     

Application of a simple extraction procedure using aqueous ammonia to the analysis of basic drugs in blood by gas chromatography

A simple and reliable previously reported extraction procedure has been extended to the analysis of a wide range of basic and neutral drugs in postmortem blood and other tissues. The method employs 200 microliters of blood treated with water and ammonia and extracted with diethyl ether. The concentrated extract is generally sufficiently clean for direct analysis by gas chromatography and high pressure liquid chromatography. Recovery, precision and linearity data are presented for selected drugs.
