Disaggregating the dependent variable in policy feedback research: an analysis of the EU Emissions Trading System

Policy Sciences - The literature on policy dynamics has long argued for a better conceptualization and measurement of the dependent variable (“policy”), but this fundamental point has...     

Humans Are Animals,Too: Critical Commonalities and Differences Between Human and Wildlife Forensic Genetics

Wildlife forensics has recently been recognized among the wide variety of forensic science disciplines. This review compares human and wildlife DNA forensics, which use the same genetic tools, but often for far different purposes. Human forensic genetics almost invariably attempts to identify individual perpetrators involved in a given crime. Wildlife forensics often determines whether a crime has occurred. In addition to techniques familiar in human laboratories, like individual matching with STRs, wildlife analysts may be asked to determine the taxonomic identity, geographic source, or sex of evidence items, or the familial relationships or minimum number of individuals among a group of samples. This review highlights the common questions, legal framework, databases, and similar validation requirements to foster understanding between disciplines. Based on this understanding, human and wildlife DNA practitioners may work together and learn from each other in order to elevate the discipline of forensic genetics.     

Interaction between carbon monoxide and ethanol in fire fatalities.

Impairment due to ethanol is clearly a risk factor in deaths due to fire. However, it is less clear whether there is a physiological interaction between ethanol and carbon monoxide (CO) that would alter the carboxyhemoglobin saturation level (COHb sat.) that accounts for death. In an attempt to explore this issue further, 196 fire fatalities investigated by the Office of the Chief Medical Examiner, State of Maryland over a 3-year period were examined. COHb sat. and blood ethanol concentrations (BAC) were tabulated. Twelve cases positive for therapeutic or abused drugs other than lidocaine or atropine were excluded; 184 cases were included. The data indicate that ethanol does not affect the COHb sat. that accounts for death, since the percentage of cases positive for ethanol at a given COHb range shows no trends. Therefore, we conclude that although ethanol remains a risk factor in fire fatalities, the risk appears to be related to the impairment that it produces as opposed to a direct interaction with CO.     

Comparison of point-of-collection screening of drugs of abuse in oral fluid with a laboratory-based urine screen.

Oral fluid is becoming increasingly useful for the detection of drugs, since it is a non-invasive specimen to collect and, because collection is directly observed, it is difficult to adulterate. A point-of-collection (POCT) oral fluid drug analysis kit has been developed for use in many drug testing situations. This paper summarizes the results of field evaluations of the ORALscreen System for screening of drugs in oral fluid. The ORALscreen System consists of an oral fluid collection device and a test device containing a lateral flow membrane immunoassay system. Paired samples (oral fluid and urine) were collected from drug users and the results from the ORALscreen POCT system were compared to urine screening results conducted in a licensed laboratory. The results demonstrate that the ORALscreen System has excellent percent agreement with the laboratory-based urine screening test results for the detection of cocaine and opiates through 2.5-3 days following drug use, respectively. Tetrahydrocannabinol (THC) was detected by ORALscreen on the day of use and 1 day after use. Good correlation between urine and oral fluid screening results was observed for the methamphetamine positive samples; however, the number of days following drug use was not determined.     

Workforce Crisis in Residential Aged Care: Insights from Rural,Older Workers

In Australia, workforce shortages in residential aged care present a significant challenge for the aged care industry. The growing demand for workers in aged care, combined with the shrinking supply of younger workers entering the field, highlights a future workforce crisis. The current shortfalls are set to worsen with the retirement of a generation of women who have provided the backbone of the workforce. Although targeted retention of this group may alleviate this issue, few studies have explored the retirement decisions of this cohort. This paper reports on a qualitative study of this cohort of Victorian public sector residential aged care staff. Although current government rhetoric promotes intrinsic rewards (altruism, moral fulfilment) over extrinsic rewards (excessive workload, pay and conditions), a combination of these factors was associated with job satisfaction. It would seem timely to revisit some of these concerns to ensure an adequate and sufficiently skilled workforce.     

Analytics and Beliefs: Competing Explanations for Defining Problems and Choosing Allies and Opponents in Collaborative Environmental Management

The rationale for collaborative environmental management often hinges on two factors: first, specialized training creates biased analytics that require multidisciplinary approaches to solve policy problems; second, normative beliefs among competing actors must be included in policy making to give the process legitimacy and to decide trans‐scientific problems. These two factors are tested as drivers of conflict in an analysis of 76 watershed partnerships. The authors find that analytical bias is a secondary factor to normative beliefs; that depicting the primary driver of conflict in collaborative environmental management as between experts and nonexperts is inaccurate; that compared to the “life” and “physical” sciences, the social sciences and liberal arts have a stronger impact on beliefs and choice of allies and opponents; and that multiple measures are needed to capture the effect of analytical biases. The essay offers lessons for public administrators and highlights the limitations and generalizations of other governing approaches.
