Cost benefit analysis vs. referenda
We consider a planner who chooses between two possible public policies and ask whether a referendum or a cost benefit analysis leads to higher welfare. We find that a referendum leads to higher welfare than a cost benefit analyses in "common value" environments. Cost benefit analysis is better in "private value" environments.Cost benefit analysis, elections, referenda, project evaluation
Federal Malpractice in Indian Country and the Law of the Place : A Re-Examination of Williams v. United States under Existing Law of the Eastern Band of Cherokee Indians
This paper analyzes the law applicable in malpractice cases occurring within Indian Country and brought under the Federal Tort Claims Act, applying the Law of the Place. In particular, this paper argues that the law of the Eastern Band of Cherokee Indians, including the customs and traditions of the Tribe, should have been applied by the Federal Courts in lieu of the law of North Carolina in Williams v. United States. The paper concludes by suggesting that a complete laboratory of Federalism should include the application of the laws of the respective Tribes where Federal medical negligence occurs

FADGI on a Budget: Improving Digital Images for Library Staff and Faculty
This case study describes the photography equipment and setup of San Francisco State University’s Digital Scholarship Center, and the testing and manipulation of these elements to reach the 4-star tier of the Federal Agencies Digital Guidelines Initiative (FADGI) technical guidelines. It describes how, with a few tools like a color target and image analysis software, cultural heritage digitization units with limited photography skills can markedly increase the quality of their digital images with experimentation, creativity, and the photography equipment they already have
Short-term Response of Holcus lanatus L. (Common Velvetgrass) to Chemical and Manual Control at Yosemite National Park, USA
One of the highest priority invasive species at both Yosemite and Sequoia and Kings Canyon national parks is Holcus lanatus L. (common velvetgrass), a perennial bunchgrass that invades mid-elevation montane meadows. Despite velvetgrass being a high priority species, there is little information available on control techniques. The goal of this project was to evaluate the short-term response of a single application of common chemical and manual velvetgrass control techniques. The study was conducted at three montane sites in Yosemite National Park. Glyphosate spotspray treatments were applied at 0.5, 1.0, 1.5, and 2.0% concentrations, and compared with hand pulling to evaluate effects on cover of common velvetgrass, cover of other plant species, and community species richness. Posttreatment year 1 cover of common velvetgrass was 12.1% 6 1.6 in control plots, 6.3% 6 1.5 averaged over the four chemical treatments (all chemical treatments performed similarly), and 13.6% 6 1.7 for handpulled plots. This represents an approximately 50% reduction in common velvetgrass cover in chemically- treated plots recoded posttreatment year 1 and no statistically significant reduction in hand pulled plots compared with controls. However, there was no treatment effect in posttreatment year 2, and all herbicide application rates performed similarly. In addition, there were no significant treatment effects on nontarget species or species richness. These results suggest that for this level of infestation and habitat type, (1) one year of hand pulling is not an effective control method and (2) glyphosate provides some level of control in the short-term without impact to nontarget plant species, but the effect is temporary as a single year of glyphosate treatment is ineffective over a twoyear period
Structure determination of disordered materials from diffraction data
We show that the information gained in spectroscopic experiments regarding
the number and distribution of atomic environments can be used as a valuable
constraint in the refinement of the atomic-scale structures of nanostructured
or amorphous materials from pair distribution function (PDF) data. We
illustrate the effectiveness of this approach for three paradigmatic disordered
systems: molecular C60, a-Si, and a-SiO2 . Much improved atomistic models are
attained in each case without any a-priori assumptions regarding coordination
number or local geometry. We propose that this approach may form the basis for
a generalised methodology for structure "solution" from PDF data applicable to
network, nanostructured and molecular systems alike.Comment: 4 pages, 3 figures, set out as for PR
Formulas in Physics Have a “Standard” Form
The article discusses the importance of the ordering of symbols in physics formulas and identify conventions that rule the standard form for how formulas are written and interpreted. The elements of this form consisting of constants, parameters, and variables have been identified. Instructors are encouraged to make this convention explicit and encourage its use to assist students
Stochastic Games, Oligopoly Theory and Competitive Resource Allocation
We define discrete time sequential games which are multiperson Markov decision processes. The extant theory is sketched and compared with our assessment of research needs in dynamic models of oligopoly and other competitive resource allocation problems. A special class of economic survival games is noted
Cost-effectiveness of HCV case-finding for people who inject drugs via dried blood spot testing in specialist addiction services and prisons
ObjectivesPeople who inject drugs (PWID) are at high risk for acquiring hepatitis C virus (HCV), but many are unaware of their infection. HCV dried blood spot (DBS) testing increases case-finding in addiction services and prisons. We determine the cost-effectiveness of increasing HCV case-finding among PWID by offering DBS testing in specialist addiction services or prisons as compared to using venepuncture.DesignCost-utility analysis using a dynamic HCV transmission model among PWID, including: disease progression, diagnosis, treatment, injecting status, incarceration and addition services contact.Setting uk interventionDBS testing in specialist addiction services or prisons. Intervention impact was determined by a meta-analysis of primary data.Primary and secondary outcome measuresCosts (in UK £, £1=US$1.60) and utilities (quality-adjusted life years, QALYs) were attached to each state and the incremental cost effectiveness ratio (ICER) determined. Multivariate uncertainty and one-way sensitivity analyses were performed.ResultsFor a £20 000 per QALY gained willingness-to-pay threshold, DBS testing in addiction services is cost-effective (ICER of £14 600 per QALY gained). Under the base-case assumption of no continuity of treatment/care when exiting/entering prison, DBS testing in prisons is not cost-effective (ICER of £59 400 per QALY gained). Results are robust to changes in HCV prevalence; increasing PWID treatment rates to those for ex-PWID considerably reduces ICER (£4500 and £30 000 per QALY gained for addiction services and prison, respectively). If continuity of care is >40%, the prison DBS ICER falls below £20 000 per QALY gained.ConclusionsDespite low PWID treatment rates, increasing case-finding can be cost-effective in specialist addiction services, and in prisons if continuity of treatment/care is ensured
