The demand revealing process: To distribute the surplus

Contrary to established, frequently repeated proposition that its budget surplus cannot be distributed to taxpayers without disturbing the incentive compatibility of the demand revealing process (DRP), the surplus can be distributed by reapplying the key concept of the DRP. There will remain an aggregate refund error that in a Bayesian sense is random with zero mean, and which vanishes O(1/N)² as the economy becomes large through replication. To dela with income effects. when one does not restrict the domain of the mechanism to separable utility functions, I suggest a variation of the DRP that preserves its incentive compatibility wgeb N is finite.     

Signals from the Tenth Justice: The Political Role of the Solicitor General in Supreme Court Decision Making

Conventional explanations of the solicitor general's influence on the Supreme Court emphasize his expertise or experience. We articulate and test a more political account based on insights from signaling theory. We argue justices will be more receptive to signals from the solicitor general (S.G.) when either the justice and S.G. are ideologically proximate or the S.G.'s signal is contrary to his ideological predisposition. We test our account over the period from 1953 to 2002 using a newly developed interinstitutional measure of ideology that places executive and judicial actors on the same spatial scale. Our results highlight the political nature of the S.G.'s influence, challenging the received wisdom about the S.G.'s impact on the Supreme Court.     

Lindahl mechanisms and free riders

Several authors have proposed mechanisms whose Nash-equilibria yield Lindahl tax allocations; however, as is well known, so does the Lindahl procedure with an auctioneer. Moreover, the game forms of all these mechanisms, and of any as yet undiscovered such mechanism, all have the same normal form as does the Lindahl procedure without an auctioneer. The manipulative Nash equilibria are consequently the same for all these mechanisms, so that all have the traditional free-rider problem and all have the same outcome under strategic behavior.     

The value of the Duquénois test for cannabis--a survey.

The Duquénois test is employed throughout the world as part of the identification procedure for cannabis. A survey of results published for more than 400 herbally derived and botanical materials originating from some 270 different plant species is presented. A survey of results from some 200 organic compounds is also presented. The data show that the D-L modification is the most specific. There is no published report of an obviously botanical material, apart from cannabis, that gives a positive D-L test. Apart from cannabinoids, some resorcinol derivatives give a positive test. All of the materials are easily distinguished from cannabis by TLC.     

The Transitioning Families Therapeutic Reunification Model in Nonfamilial Abductions

The existing literature on abduction reunification is limited and evolving. Although guidelines for model service approaches exist, few programs address the unique challenges of reunifying children and families following abduction. This article delineates a family‐based reunification model that has assisted families affected by abduction since 2006. Model components include a team‐centered approach, a stage‐oriented reunification process, and pitfalls and strategies related to intersystem collaboration. We present the value of a family‐systems, solution‐focused, trauma‐informed, and case‐specific approach to therapeutic reunification following child abduction. Evidence that is contrary to the popular notion of Stockholm's syndrome is also marked. Research on the efficacy of therapeutic reunification is essential for the growth of systems equipped to address the dynamic needs of these families. Accordingly, suggestions for evaluation research are proposed.     

Computer program claims held patentable in the UK

Where claims for computer implemented methods and apparatusare valid, in principle an equivalent claim to the program itselfshould be allowable.     

A Quantitative Assessment of Zygomatic Projection for Ancestry Estimation

Anterior zygomatic projection (ZP) is historically referenced as a useful trait in ancestry estimation, particularly when differentiating between Native Americans and U.S. Whites and Blacks. However, methods of assessing ZP vary, are susceptible to multiple interpretations, and have not been quantitatively validated. This study uses 228 3D surface scans of U.S. Whites, U.S. Blacks, and Native Americans to quantitatively test the ZP methods published by Rhine in 1990 (Skeletal attribution of race: methods for forensic anthropology, Albuquerque, NM, Maxwell Museum of Anthropology, 1990) and Bass in 1995 (Human osteology: a laboratory and field manual, Columbia, MO: Missouri Archaeological Society, 1995). Two ZP angles and two distances, representing method interpretations, were collected and analyzed via ANOVA and discriminant function analyses. Although significant ancestry differences were found across all variables, only the Bass inferior zygomatic distance successfully differentiated the pooled Native American group from pooled U.S. Whites/Blacks (73.7% correct). Arctic Native Americans, displaying the most projecting zygomas, are driving group differences. Significant overlap in measurement distributions were observed between groups in all variables, indicating limited forensic utility.     

Partisan Bridges to Bipartisanship: The Case of Contraceptive Coverage

The negative consequences of polarization have been pointed to by scholars and politicians alike as evidence of a need for a renewal of bipartisanship. However, scholarship on bipartisanship remains limited. This article develops a theory of partisan bridging that predicts when and why certain legislators might be willing to cross the partisan aisle. I argue that personal preferences can lead some legislators to cross the aisle in search of consensus, in effect serving as “partisan bridges.” I test my theory by examining the role of Republican women in the diffusion of contraceptive coverage at the state level. Through an individual‐level analysis of sponsorship and vote choice and an aggregate‐level analysis of policy diffusion, I find that moderate Republican women at times served as critical actors in the policy process.
