Identification of Opioids and Related Substances using Handheld Raman Spectrometers

This study describes the performance of handheld Raman devices for detecting one hundred opioids and related substances including fentanyl and several analogs. Using a single “parent” device, signatures (spectra) with excellent signal-to-noise ratios were generated using <5 mg of most compounds. The signatures were added to a method (library), which was electronically transferred to three “daughter” devices. The devices were able to discriminate different salt forms and isomers. On average, the daughter devices yielded a true-positive rate of 97.3% for generating an alarm for opioids and were 93.3% effective for correctly identifying the opioid. The devices yielded true-negative, false-positive and false-negative rates of 100%, 0%, and 2.7%, respectively, where false negatives were due to weak signal and fluorescence. These data demonstrate that the parent-daughter electronic transfer method was successful and effective, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices.     

Blast Suppression Foam,Aqueous Gel Blocks,and their Effect on Subsequent Analysis of Forensic Evidence*

In addition to having blast mitigation properties, aqueous foam concentrate AFC-380 blast suppression foam is designed to capture aerosolized chemical, biological, and radioactive particles during render-safe procedures of explosive devices. Exposure to aqueous environments and surfactants may negatively affect forensic evidence found at the scene, but the effects of AFC-380 foam and aqueous gel on the preservation and subsequent analysis of forensic evidence have not previously been investigated. Sebaceous finger and palm prints and DNA samples on paper, cardboard, tape, and various metal and plastic items, along with hairs, carpet and yarn fibers, and inks and documents, were exposed to AFC-380 foam. Similar mock evidence was also exposed to a superabsorbent gel of the type found in aqueous gel blocks used for shrapnel containment. Exposure to foam or aqueous gel was associated with a dilution effect for recovered DNA samples, but quality of the samples was not substantially affected. In contrast, exposure to AFC-380 foam or gel was detrimental to development of latent finger and palm prints on any substrate. Neither the hair nor the fiber samples were affected by exposure to either the foam or gel. Indented writing on the document samples was detrimentally affected by foam or gel exposure, but not inks and toners. The results from this study indicate that most types of forensic evidence recovered after being exposed to aqueous gel or blast suppression foam can be reliably analyzed, but latent finger and palm prints may be adversely affected.     

Socially Demoralizing Environments and the Development of the Street Code from Childhood to Emerging Adulthood

This study examines hypotheses regarding patterns of developmental change in street code commitment from childhood through emerging adulthood. It tests whether street code commitment demonstrates developmental stability or if it fluctuates in response to evolving socially demoralizing conditions. Latent growth curve and parallel process models are applied to longitudinal data from an African American sample. Confirmatory factor analysis tests the degree to which neighborhood violence, peer processes, and family hostilities combine to form a latent construct of socially demoralizing environments. Analysis also tests measurement invariance across the study assessment periods. Street code commitment demonstrates a non-linear growth pattern across time. Commitment increases in childhood, peaks in late adolescence, and declines in emerging adulthood. Exposure to demoralizing social environments demonstrates a similar pattern of change characterized by a peak in adolescence followed by a gradual decline. Harsh childhood social environments affect the initial levels but not the growth of the street code. Street code commitment fluctuates in response to contemporaneous environmental conditions. The street code is malleable from childhood through emerging adulthood. Commitment to the street code is not a stable product of socialization or early childhood social environmental exposures. The degree to which individuals embrace the code is largely a function of their current social environment.

Organizational design and its consequences for administrative reform: Historical lessons from the U.S. Budget and Accounting Act of 1921

The landmark U.S. Budget and Accounting Act of 1921 (BAA) instituted a series of administrative reforms that proponents claimed would improve budgetary control, stability, and coherence. We maintain that the compatibility of governance structures between agency and system levels is critical for understanding why these administrative centralization efforts were successful in achieving these aims for some federal agencies but not others. The BAA reforms impact on budgetary outcomes is evaluated using panel data on major U.S. federal agencies between 1894 and 1940. Applying semiparametric heterogeneous treatment estimation techniques, we find compelling support that administrative centralization of the federal budgetary process enhanced budget stability and coherence for executive departments while resulting in a lower caliber of budgetary performance for independent agencies. These findings imply that system‐level administrative centralization efforts may be effective only when public agencies are structurally amenable to such reforms.     

Defining Mediator Knowledge and Skills

A two-year collaboration among researchers, practitioners, and advisers from the major national organizations of mediators produced a job analysis relevant to mediators involved in interpersonal disputes (i.e., divorce, community, formal parent-child mediation, etc.). One byproduct of the job analysis is an extensive list of the knowledge areas and skills important to effective job performance. This essay defines the knowledge and skill areas that emerged from the analysis.     

Citizens and Resource Allocation: Improving Decision Making with Interactive Web-Based Citizen Participation

Collective consumption and benefit characterize many government services. Moreover, government services are mostly paid for collectively through taxes—there is little or no relationship between the taxes paid by a household and its use of a particular service. Public sector decision makers face complex budget problems with difficult solutions. Involving citizens meaningfully in these decisions has long been a conundrum. The authors teamed up with the town of West Hartford, Connecticut, to develop a Web-based survey to overcome some of these participation problems and help decision makers better understand citizen preferences. The Web survey allowed for real-time interactivity and was tailored to present respondents with trade-offs between service levels and taxes.     

Bequests, sibling rivalry, and rent seeking

We examine bequest-sharing rules where sibling rivalry creates wasteful competition for intergenerational transfers. We show that equal division of bequests minimizes rent-seeking expenditures by siblings while primogeniture maximizes rent-seeking costs. Our results lend theoretical support to the empirical findings of equal bequests without appeal to complex models of the parent-child relationship.
