USING BOTH SOCIOLOGICAL AND ECONOMIC INCENTIVES TO REDUCE MORAL HAZARD
Economists tend to focus on monetary incentives. In the model developed here, both sociological and economic incentives are used to diminish the apparent moral hazard problem existing in commodity grading. Training that promotes graders' response to sociological incentives is shown to increase expected benefits. The model suggests that this training be increased up to the point where the marginal benefit due to training equals its marginal cost. It may be more economical to influence the grader's behavior by creating cognitive dissonance through training and rules rather than by using economic incentives alone.Marketing,

Embracing Deference
A fundamental conceptual problem has long dogged discussions about scientific and other expert evidence in the courtroom. In American law, the problem was most famously posed by Judge Learned Hand, who asked: [H]ow can the jury judge between two statements each founded upon an experience confessedly foreign in kind to their own? It is just because they are incompetent for such a task that the expert is necessary at all. This puzzle, sometimes known as the expert paradox, is quite general. It applies not only to the jury as factfinder, but also to the judge as gate- keeper under the Daubert v. Merrell Dow Pharmaceuticals, Inc. regime and Federal Rule of Evidence 702. It also applies when there is no jury at all, whether in a bench trial, administrative proceeding, or civil law jurisdiction. When it comes to scientific and other specialized knowledge, legal actors are inevitably non-experts. And if legal actors are faced with the so- called battle of the experts, how are they to decide between the warring experts? After all, to quote Judge Hand again, [i]t is just because they are incompetent for such a task that the expert is necessary at all. As one of us has previously argued, because of this epistemic competency problem, the Daubert approach to expert evidence is a mistake. The solution to the problem of expert evidence is not judicial gatekeeping, but rather to change the substantive question asked of legal actors

Subclinical myocardial disease by cardiac magnetic resonance imaging and spectroscopy in healthy HIV/Hepatitis C virus-coinfected persons.
Objective The contribution of hepatitis C virus (HCV) infection to the risk of heart failure in human immunodeficiency virus (HIV)-coinfected persons is unknown. The objective was to characterize cardiac function and morphology in HIV-treated coinfected persons. Methods In a cross-sectional study, HIV-infected patients virologically suppressed on antiretroviral therapy without known cardiovascular disease or diabetes mellitus underwent cardiac magnetic resonance imaging and spectroscopy for measures of cardiac function, myocardial fibrosis, and steatosis. Results The study included 18 male patients with a median age of 44 years. Of these, 10 had untreated HCV coinfection and eight had HIV monoinfection. Global systolic and diastolic function in the cohort were normal, and median myocardial fat content was 0.48% (interquartile range 0.35-1.54). Left ventricular (LV) mass index and LV mass/volume ratio were significantly greater in the HIV/HCV-coinfected group compared with the HIV-monoinfected group. In the HIV-monoinfected group, there was more myocardial fibrosis as measured by extracellular volume fraction. Conclusions There were differences between HIV/HCV-coinfected and HIV-monoinfected patients in cardiac structure and morphology. Larger studies are needed to examine whether HIV and HCV independently contribute to mechanisms of heart failure
Participation of women in HIV clinical trials: the IPEC-FIOCRUZ experience

In Brazil, for example, 240,000 women are infected with HIV, rates of infection in women have increased over the last two decades, and addressing HIV prevention and treatment for women at risk for, or living with, HIV/AIDS remains a challenge. To better address the needs of women living with HIV in Brazil, the Instituto de Pesquisa Clínica Evandro Chagas – Fundação Oswaldo Cruz (IPEC-FIOCRUZ) HIV Women’s Cohort was established in 1996 to study the natural history of women seeking HIV care. This analysis describes the characteristics of women in the cohort who participated in HIV clinical trials between 1999 and 2008.Methods: A total of 736 Women’s Cohort participants were in active follow-up and 665 participants from the Women’s Cohort were included in univariable and multivariable analyses to determine socioeconomic and sociodemographic factors associated with women’s participation in HIV clinical trials at our site.Results: Of the complete cohort, 23% participated in a clinical trial between January 1999 and July 2008. Odds of participation decreased for women who were younger than 35 years old, currently employed, had an HIV-positive sexual partner, and/or who reported a lifetime history of illicit drug use. Alternatively, the odds of participation increased for women who had more than 8 years of formal education, were living independently, and/or were married or cohabitating.Conclusion: The rate of participation in HIV clinical trials by women in the IPEC-Fiocruz Cohort was similar to other published cohorts, but identification of local risk factors and barriers to participation remains important. Our analysis offers a novel description of the factors associated with participation in HIV clinical trials among women in care at IPEC-FIOCRUZ in Rio de Janeiro, Brazil.Keywords: AIDS, Brazil, South America, clinical trial participation&nbsp
