A challenge for environmental governance: institutional change in a traditional common-property forest system

This article examines how the Miskito peoples of Río Plátano, Honduras have responded to agricultural expansion by migrant farmers and ranchers onto their ancestral forest lands, and considers the policy options for supporting the common-property system of the Miskito and the forests they have historically conserved. The analysis compares institutional changes in the common-property systems of three Miskito communities, each with a different history of colonization. The findings illustrate that the Miskito response to the colonists has been multifaceted, and that while the Miskito leaders have made institutional changes to strengthen their common-property system, these changes are not necessarily reflected in the daily decisions of the Miskito people. The findings suggest that policies that support indigenous rulemaking abilities, specifically policies that legitimize indigenous rights to their lands and provide the resources to apply those rights, may be vital to maintain robust common-property systems and the frontier forests in the region.     

A comprehensive method for the assessment of industrial injury events

Because work‐related injuries are infrequent and often poorly documented, injury event operationalizations beyond recorded rates would be beneficial. This study describes a method that uses self‐reported and recorded events.

Researchers interviewed workers and obtained recorded events from personnel files to develop the near miss and unreported injury events measures. The self‐reported event measures, with other safety variables and demographics, were then administered to two groups of plant workers (N = 115 and N = 120). Results indicated that self‐reported events differed from recorded events and are related to other work injury variables (e.g., work hazards, overtime). An expanded safety protocol such as this one may provide additional tools to investigate the injury event process.     

Believing is seeing? Investigating the perceived accuracy of criminal psychological profiles

This study investigated whether perceptions of criminal psychological profiles are influenced by the identity of the profile's author. Police officers were given a profile they were told was written by either a professional profiler or by an unspecified author. When judged in relation to the actual perpetrator of the crime, police officers tended to perceive greater accuracy in a profile when it was labeled as authored by a professional profiler independent of the actual content of the profile. But officers' judgments of the usefulness of the profile were not affected by knowledge of who wrote the profile. Explanations for this result focus on the ambiguous nature of criminal profiles and how this ambiguity enhances the likelihood that beliefs about the validity of profiling can color perceptions of the content of the profile.     

Mitochondrial DNA and STR analyses of maggot crop contents: effect of specimen preservation technique

DNA analysis of maggot crop contents can be used to identify a missing body or aid entomologists with interpreting evidence used for PMI estimations. Entomological evidence is often collected and preserved to keep identifiable external features intact. The preservation methods currently in use may not be suitable for preserving DNA in the maggot crop for later analysis. In this study, carrion maggots raised on human tissue were preserved under the following 8 preservation conditions: no fluid at -70 degrees C, no fluid at 4 degrees C, no fluid at 24 degrees C, 70% ethanol at 4 degrees C, 70% ethanol at 24 degrees C, 95% ethanol at 24 degrees C, Kahle's solution at 24 degrees C and formaldehyde at 24 degrees C. Maggots were dissected following 2 weeks, 8 weeks and 6 months of preservation. The maggot crops were extracted, human DNA was quantitated, and an attempt was made at amplifying mitochondrial DNA (mtDNA) and short tandem repeat (STR) loci. Both mtDNA and STRs were successfully amplified from maggots stored in ethanol or without any preservation fluid. Formalin-containing preservation solutions reduced the recovery of DNA. The best results were observed from maggots stored without any preservation fluid at -70 degrees C.     

Judicial Selection: Politics,Biases, and Constituency Demands

The determinants of recent U.S. districtcourt judges and appellate court judgesselection have been subject of much debate,but little systematic evidence has beenpresented to substantiate claims regardingdiscrimination against particular groups ofjudicial nominees, nor regarding the lengthof the appointment process. We study boththe length of the nominations process, andthe likelihood of confirmation andemphasize the role of Senatorial seniorityand agenda control in the confirmationsprocess. We find that Senators with agendacontrol have a positive effect on the speedand likelihood of confirmation and thatnominees from states with comparativelysenior Senators receive expedited treatmentrelative to other nominees. Althoughpolitics matter in the confirmationprocess, Senators are responsive to aperceived ``shortage'' of judges, since theyfill seats faster when a relatively largenumber of court seats are vacant. Nomineeswith higher personal qualifications arealso more likely to experience success inconfirmations. We found no evidence ofgender or race discrimination on the partof the Senate.     

THE INTERNAL AND EXTERNAL VALIDITY OF THE REGRESSION DISCONTINUITY DESIGN: A META‐ANALYSIS OF 15 WITHIN‐STUDY COMPARISONS

Theory predicts that regression discontinuity (RD) provides valid causal inference at the cutoff score that determines treatment assignment. One purpose of this paper is to test RD's internal validity across 15 studies. Each of them assesses the correspondence between causal estimates from an RD study and a randomized control trial (RCT) when the estimates are made at the same cutoff point where they should not differ asymptotically. However, statistical error, imperfect design implementation, and a plethora of different possible analysis options, mean that they might nonetheless differ. We test whether they do, assuming that the bias potential is greater with RDs than RCTs. A second purpose of this paper is to investigate the external validity of RD by exploring how the size of the bias estimates varies across the 15 studies, for they differ in their settings, interventions, analyses, and implementation details. Both Bayesian and frequentist meta‐analysis methods show that the RD bias is below 0.01 standard deviations on average, indicating RD's high internal validity. When the study‐specific estimates are shrunken to capitalize on the information the other studies provide, all the RD causal estimates fall within 0.07 standard deviations of their RCT counterparts, now indicating high external validity. With unshrunken estimates, the mean RD bias is still essentially zero, but the distribution of RD bias estimates is less tight, especially with smaller samples and when parametric RD analyses are used.
