Post Flight Dynamic Analysis Simulation

Digital six-degrees-of-freedom, open loop Saturn 5 first stage flight evaluation simulation program obtains post flight simulation of the launch vehicle using actual flight data as input. Results are compared with measured data. For preflight analysis, the program uses predicted flight data as input

Initial Data for Numerical Relativity

Initial data are the starting point for any numerical simulation. In the case of numerical relativity, Einstein's equations constrain our choices of these initial data. We will examine several of the formalisms used for specifying Cauchy initial data in the 3+1 decomposition of Einstein's equations. We will then explore how these formalisms have been used in constructing initial data for spacetimes containing black holes and neutron stars. In the topics discussed, emphasis is placed on those issues that are important for obtaining astrophysically realistic initial data for compact binary coalescence.Comment: 50 pages, LaTeX(livrev.cls), Review article for "Living Reviews in Relativity" (http://www.livingreviews.org/), July 200

Personal Relationships and Support for Gay Rights

Since the early days of the gay liberation movement, activists have argued that coming out to heterosexuals would increase acceptance of homosexuality and support for gay rights. Though the empirical research has generally supported this hypothesis, it has not adequately controlled for reciprocal causation: having positive attitudes toward homosexuality increases the probability that a gay, lesbian, or bisexual person (LGB) will come out to you. This paper re-estimates the effect of knowing LGBs on support for gay rights using individual-level data from 27 surveys of the national population conducted since 1983. I first assess whether the same characteristics predict both attitudes and acquaintance. I next examine the effect of knowing LGBs on acceptance of homosexuality and support for gay rights in three ways: using logit models that control for the demographic and political variables used in step one, using propensity score matching to restrict comparisons of those who know LGBs to others who are as similar as possible, and using logit models for support for gay rights that also control for acceptance of homosexuality. Findings confirm that knowing LGBs affects beliefs on the morality of homosexual relations, employment discrimination, gays in the military, sodomy laws, and samesex marriage. Working Paper 07-1

The Friends and Family Plan: Assessing the Impact of Knowing Someone Gay on Support for Gay Rights

I estimate the impact of knowing someone gay on acceptance of homosexuality and support for gay rights. Method: Logit analyses on individual-level data from 27 national surveys control for demographic and political variables that predict both acquaintance with lesbians, gay men, and bisexuals (LGBs) and support for gay rights. Findings: Knowing LGBs affects beliefs on the morality of homosexual relations, employment discrimination, gays in the military, sodomy laws, and same-sex marriage. Conclusion: Coming out remains an important strategy in the battle for gay rights. Working Paper 08-1
