Centralizing Advisory Systems: Presidential Influence and the U.S. Foreign Policy Decision-Making Process

This study is motivated by a simple yet vitally important question for an understanding of U.S. foreign policy. Quite simply, how does a president's choice of management style influence the U.S. foreign policy decision-making process and decision outcomes? Presidents play a critical role in the formulation of U.S. foreign policy; however, the presidential studies literature and foreign policy analysis literature arrive at very different conclusions regarding how presidents influence the policy process and both are often inaccurate. This study develops an Advisory Systems Typology to address how presidents influence the decision-making process. In addressing this question, this study overcomes the deficiencies of both the presidential studies and foreign policy analysis literature. Four different types of decision-making processes are produced by a president's choice of advisory structure and level of centralization. In addition, the study identifies "unstructured solutions" that indicate how the presidential advisers and president choose to resolve policy disagreements, thereby providing an indication of the decision outcome. The identified decision-making processes and their associated decision outcomes are explored using four cases of decision making on security policy drawn from the Nixon (Vietnam War), Carter (Strategic Arms Limitation Talks II), Reagan (Strategic Arms Reduction Talks I), and Clinton (Bosnia conflict) administrations. The case studies are constructed using the method of structured–focused comparisons, whereby a set of theoretically based questions and anticipated observations to those questions are made in order to guide the research and allow for comparison of decision making within and between cases.     

Sources of Transparency: Information Systems in International Regimes

Scholars and practitioners alike have stressed the important role of transparency in promoting international regime compliance and effectiveness. Yet many regimes fail to create high levels of transparency: governments and nongovernmental actors regularly fail to monitor or report on their own behavior, the behavior of other actors, or the state of the problem these regimes seek to resolve. If more transparency often, if not always, contributes to regime effectiveness, then identifying the sources of transparency becomes an important research task. Regime transparency depends upon both the demand for information and the supply of information. Specifically, regimes can seek "effectiveness-oriented" information to assess whether regime members are collectively achieving regime goals or "compliance-oriented" information to assess whether particular actors are individually fulfilling regime commitments. The incentives and capacities that relevant actors—whether governments, nongovernmental organizations, or corporate actors—have to provide such information depend on whether the regime's information system is structured around self-reporting, other-reporting, or problem-reporting. Although many of these factors are determined by characteristics of the actors involved or the structure of the problem, regimes can increase transparency by enhancing the incentives and capacity actors have to contribute to a particular regime's transparency.     

Validity testing of the TDx Cocaine Metabolite Assay with human specimens obtained after intravenous cocaine administration

Clinical specimens obtained from human subjects after intravenous cocaine administration were analyzed by the TDx Cocaine Metabolite Assay (TDx) and by GC/MS for benzoylecgonine. The TDx results were significantly correlated with results by GC/MS assay with no evidence of bias in the TDx assay. All cocaine metabolite positive specimens (greater than or equal to 300 ng/ml) were confirmed by GC/MS. Detection times to the last positive specimen by TDx assay and GC/MS assay of four subjects after a 20-mg intravenous dose of cocaine ranged from 29.3 to 39.1 h and 27.9 and 36.6 h, respectively. Overall, the TDx assay was found to be highly specific and accurate for the detection and measurement of benzoylecgonine in urine.     

Barotrauma and air embolism in hyperbaric oxygen therapy

A 69-year-old woman underwent hyperbaric oxygen therapy because of a nonhealing ulcer of her foot. During decompression, she developed a left-sided hemiplegia and confusion. Recompression resulted in transient neurologic improvement, but she eventually became comatose. Ventricular dysrhythmias developed and she died without regaining consciousness 17 h after onset of symptoms. An autopsy revealed diffuse interstitial pulmonary fibrosis with severe paracicatricial emphysema, chronic interstitial inflammation, and chronic bronchitis with abundant intrabronchial mucus. There was extensive multifocal ischemic injury of the cerebral cortex. The hippocampi, basal ganglia, and cerebellum were spared. Scattered acute myofiber necrosis was present in the heart. Clinical presentation and autopsy findings strongly support the diagnosis of air embolism and illustrate a potential risk of hyperbaric oxygen therapy in patients with preexisting pulmonary disease.     

To evaluate the utility of smaller sample sizes when assessing dental maturity curves for forensic age estimation

Dental maturation and chronological age estimation were determined from 144 healthy Western Australian individuals aged 3.6-14.5 years. The results were compared with Farah et al.'s previous study which comprised a larger heterogeneous sample of Western Australian individuals (n = 1450). Orthopantomograms were analyzed with the application of Demirjian and Goldstein's 4-tooth method based on eight stages of dental mineralization. Analysis of variance revealed no significant differences in dental maturity scores in each age group among the males in both studies; similar results were seen in the females. Paired t-tests showed no statistical significance overall between chronological and estimated ages for the males in our sample (p = 0.181), whereas the females showed significant differences (p < 0.001). Our results show that smaller samples may be used when assessing dental maturity curves for forensic age estimation.     

A comparison of Demirjian's four dental development methods for forensic age assessment

The aim of this study was to determine the comparative accuracy of Demirjian's four dental development methods for forensic age estimation in the Western Australian population. A sample comprising 143 individuals aged 4.6 to 14.5 years were assessed using Demirjian's four methods for dental development (original 7-tooth: M(2), M(1), PM(2), PM(1), C, I(2), and I(1); revised 7-tooth: M(2), M(1), PM(2), PM(1), C, I(2), and I(1); 4-tooth: M(2), M(1), PM(2), and PM(1); and an alternate 4-tooth: M(2), PM(2), PM(1), and I(1)). When comparing all four methods, the 4-tooth method overestimated age in both males and females by 0.04 and 0.25 years, respectively. The original 7-tooth was least accurate for males, while the original 7-tooth, the revised 7-tooth, and the alternate 4-tooth were unsuitable for females. Therefore, we recommend the 4-tooth method to be used for forensic age estimation in Western Australian males and females, as it has the lowest overall mean deviation and the highest accuracy.     

GeneMarker® HID: A reliable software tool for the analysis of forensic STR data

Abstract: GeneMarker^® HID was assessed as a software tool for the analysis of forensic short tandem repeat (STR) data and as a resource for analysis of custom STR multiplexes. The software is easy to learn and use, and includes design features that have the potential to reduce user fatigue. To illustrate reliability and accuracy, STR data from both single‐source and mixture profiles were analyzed and compared to profiles interpreted with another software package. A total of 1898 STR profiles representing 28,470 loci and more than 42,000 alleles were analyzed with 100% concordance. GeneMarker HID was also used to successfully analyze data generated from a custom STR multiplex, with simplified and rapid implementation. Finally, the impact of the user‐friendly design features of the software was assessed through a time scale study. The results suggest that laboratories can reduce the time required for data analysis by at least 25% when using GeneMarker HID.     

An Inside View of Police Officers�� Experience with Domestic Violence

Since the recognition of domestic violence (DV) in the late 1970s, police officers have been frontline providers. Despite their changing role as a result of the criminalization of DV, little is known about their experiences and responses to this public health issue from their unique perspective. Via focus groups, 22 police officers discussed their scope of practice and emotional reactions to DV calls. Participants reported frustration with the recurring nature of DV and with the larger systems?? lack of accountability (e.g., courts, prosecution and community) that follow their initial interventions. Participants discussed the limitations of their role as protectors of public safety, attitudes that evolve over time and their beliefs as to contributing factors that perpetuate DV. Additionally, the officers recommend: more professional training, counseling, incident debriefing for officers including feedback on case disposition, better collaboration across professional groups, and evidence-based prosecution. Harsher penalties were also recommended.
