The Role of Management and Representation in Improving Performance of Disadvantaged Students: An Application of Bum Phillips's “Don Shula Rule”1

Scholars and practitioners within the U.S. education system have focused considerable attention on developing new programs aimed at raising educational achievement for disadvantaged students. New programs are only one way to improve student performance, however; recent work in public administration suggests that public management and implementation practices might also have a large impact on student performance. Existing research shows that managerial networking, managerial quality, and effective personnel management can significantly improve the quality of the education received by disadvantaged students. Additional work highlights the contribution of representative bureaucracy. Because these research agendas have targeted the public administration literature rather than the education policy literature, this article seeks to bring this research back to education policy. Using data from several hundred Texas public school districts, spanning 1995 to 2002, and focusing on disadvantaged student performance (Latinos, blacks, and low‐income students), this article illustrates how both management and processes to enhance the representativeness of teaching faculty produce benefits for disadvantaged students.     

Does sexual dimorphism in facial soft tissue depths justify sex distinction in craniofacial identification?

Separation of male and female soft tissue depths into discrete groups for craniofacial identification implies that males and females differ enough from each other, with respect to this application, for this distinction to be useful. In this study, previously published soft tissue depth data were analyzed for sex separation. It was found that the variation within each sex was large while the variation between the sexes was small. Often the value of two standard deviations of the measurement for either sex was larger than the difference displayed between the means of each sex. Furthermore, opposite sex overlap in regions defined to be close to the male or female mean were found to be large and the amount of variance explained by sex was small (less than 6% on average). These results indicate that while male and female means at single craniofacial landmarks may differ slightly, and even at statistically significant levels, individual male and female soft tissue depths are often the same or very similar. On average, soft tissue depths of the face do display some sexual dimorphism but it is not marked and of little practical meaning for craniofacial identification where a single individual must be independently considered. Thus, there is little use in separate reporting of data for males and females and data should be combined to increase sample sizes.     

Evaluation of ephedrine, pseudoephedrine and phenylpropanolamine concentrations in human urine samples and a comparison of the specificity of DRI amphetamines and Abuscreen online (KIMS) amphetamines screening immunoassays

The purpose of this study was to evaluate the ability of two amphetamine class screening reagents to exclude ephedrine (EPH), pseudoephedrine (PSEPH), and phenylpropanolamine (PPA) from falsely producing positive immunoassay screening results. The study also sought to characterize the prevalence and concentration distributions of EPH, PSEPH, and PPA in samples that produced positive amphetamine screening results. Approximately 27,400 randomly collected human urine samples from Navy and Marine Corps members were simultaneously screened for amphetamines using the DRI and Abuscreen online immunoassays at a cutoff concentration of 500 ng/mL. All samples that screened positive were confirmed for amphetamine (AMP), methamphetamine (MTH), 3,4-Methylenedioxyamphetamine (MDA), 3,4-Methylenedioxymethamphetamine (MDMA), EPH, PSEPH, and PPA by gas chromatography/mass spectrometry (GC/MS). The DRI AMP immunoassay identified 1,104 presumptive amphetamine positive samples, of which only 1.99% confirmed positive for the presence of AMP, MTH, MDA, or MDMA. In contrast, the online AMP reagent identified 317 presumptive amphetamine positives with a confirmation rate for AMP, MTH, MDA, or MDMA of 7.94%. The presence of EPH, PSEPH, or PPA was confirmed in 833 of the 1,104 samples that failed to confirm positive for AMP, MTH, MDA, or MDMA; all of the 833 samples contained PSEPH. When compared to the entire screened sample set, PSEPH was present in approximately 3%, EPH in 0.9%, and PPA in 0.8% of the samples. The results indicate that cross reactivities for EPH, PSEPH, and PPA are greater than reported by the manufacturer of these reagents. The distribution of concentrations indicates that very large concentrations of EPH, PSEPH, and PPA are common.     

Substance use,health, and mental health: problems and service utilization among incarcerated women

This article profiles self-reported substance use, health, and mental health problems among a sample of incarcerated women in Kentucky as well as lifetime service utilization. Findings indicate that a high percentage of women reported use of alcohol, cocaine, and multiple substances during the month before incarceration. In addition, participants reported common health problems such as dental, female reproductive, physical injuries, and mental health problems including depression and anxiety. Participants reported moderate use of emergency room and mental health treatment but limited substance abuse treatment utilization. Implications for criminal justice programs and linkages with community-based aftercare services for women are recommended based on findings that health and mental health problems are associated with service utilization before incarceration.     

Predicting mouth width from inter-canine width--a 75% rule

It has been suggested that inter-canine width plus 57% of the cumulative distance between the lateral aspect of the canines and the pupil centers can be used to estimate mouth width. Evidence also suggests that the distance between the medial irises approximates actual mouth width fairly well. However, these soft tissue prediction guidelines are limited because they rely on accurate medio-lateral positioning of the pupils within the orbits, for which no systematic empirical evidence appears to exist at this stage. It would, therefore, be more appropriate to use only known hard tissue landmarks in mouth width prediction. This study reports the results of using inter-canine width as a percentage of mouth width for its prediction. This method seems favorable in comparison to the other guidelines because it is as accurate, uses known hard tissue landmarks, and does not rely on assumptions concerning pupil location. Estimating mouth width by using the canines alone, therefore, seems the best guideline to use in facial approximation techniques, at least given knowledge existing at this stage.     

China, Nuclear Security and Terrorism: Implications for the United States

This article outlines Chinese strategic nuclear forces and the Chinese philosophical approach to nuclear security. It then focuses on the domestic conditions in China which could precipitate vulnerabilities to its nuclear forces. From information about internal security conditions in China, specific internal threats to Chinese nuclear security will be derived. Based on these threats, several outsider and insider scenarios will be outlined involving a variety of terrorist or terrorist related behaviors. These notional scenarios will include everything from overrun or attack, to diversion, to cyber terrorism, to sabotage. The article will then cover what these scenarios and the possible Chinese reaction to them may mean for the security, military and diplomatic strategies of the United States.
