Users guide: The LaRC human-operator-simulator-based pilot model

A Human Operator Simulator (HOS) based pilot model has been developed for use at NASA LaRC for analysis of flight management problems. The model is currently configured to simulate piloted flight of an advanced transport airplane. The generic HOS operator and machine model was originally developed under U.S. Navy sponsorship by Analytics, Inc. and through a contract with LaRC was configured to represent a pilot flying a transport airplane. A version of the HOS program runs in batch mode on LaRC's (60-bit-word) central computer system. This document provides a guide for using the program and describes in some detail the assortment of files used during its operation

Trends of Migration and their Effects on Youth in Nicaragua

Extensive research has been conducted about global migration, instigators of certain migrant patterns, and economic impacts from these mass movements. However, there is limited research on the social and psychological impacts on the families that are left waiting for the return of their loved ones. This paper aims to fill this gap by analyzing changes in Nicaraguan family life after a family member migrates, specifically a parent. This study is based on the qualitative research that Universidad Centroamericana and Seattle University students and faculty conducted in Chinandega, Nicaragua, in June 2015 and 2016. Interviews were analyzed to consider how the roles of grandmothers as providers for children of migrants, the responsibilities youth take on within families with absent parents, and the absence of parents affect youth emotionally. Our conclusions show that the migration of parents contributes to a curtailed childhood for children because they tend to take on major parental responsibilities within the household after the parent leaves. Additionally, while under the primary care of grandparents, youth tend to also fill roles that their elderly caregivers are no longer capable of performing. This paper aims to bring attention to how outward migration has restructured Nicaraguan society and nuclear families, and how the absence of one or both parents has long-term effects on youth. In doing so, we hope to suggest ways in which future research may be focused

Process Evaluation of a Peer-Driven, HIV Stigma Reduction and HIV Testing Intervention in Latino and African American Churches.

Purpose: Faith-based organizations may be effective in addressing HIV-related disparities, but few interventions have been implemented across diverse churches. The Facilitating Awareness to Increase Testing for HIV (FAITH) intervention harnessed peer leadership to decrease HIV stigma and promote HIV testing in African American and Latino congregations. A pilot study found more consistent effects among Latino congregations. This process evaluation evaluates implementation of FAITH to better understand the pilot study's findings. Methods: Data sources included HIV education and peer leader workshop evaluation forms, participant views of the community's perspective of HIV, and peer leader follow-up interviews. Data were triangulated with systematic observation notes and analyzed using process-related themes of recruitment, reach, context, implementation, dose-delivered, and fidelity. Results: At the Latino churches (compared to the African American church), facilitators spent more time addressing community-based misconceptions about HIV. The peer leader model was well received, especially among Latino participants, and most said that after the workshop they felt comfortable speaking with others about HIV-related topics. Latino peer leaders reported speaking with up to 20 people within their social networks (particularly with family members); African Americans reported up to 4. Implementation challenges at the African American church may have contributed to the limited intervention effects. Nevertheless, we found the peer motivator model feasible and acceptable across diverse faith settings. Conclusion: Peer-based models within faith settings are promising for addressing HIV. However, differences among groups in HIV knowledge, social network characteristics and norms, and church preferences may influence overall effectiveness

Structure of the near-surface layers of the Sun: asphericity and time variation

We present results on the structure of the near-surface layers of the Sun obtained by inverting frequencies of high-degree solar modes from "ring diagrams". We have results for eight epochs between June 1996 and October 2003. The frequencies for each epoch were obtained from ring diagrams constructed from MDI Dopplergrams spanning complete Carrington rotations. We find that there is a substantial latitudinal variation of both sound speed and the adiabatic index Gamma_1 in the outer 2% of the Sun. We find that both the sound-speed and Gamma_1 profiles change with changes in the level of solar activity. In addition, we also study differences between the northern and southern hemispheres of the Sun and find a small asymmetry that appears to reflect the difference in magnetic activity between the two hemispheres.Comment: To appear in ApJ (January 2007

Simulations in Clinics, Contract Drafting, and Upper-Level Courses

I teach in a transactional clinic called the Urban Development Law Clinic. In my Clinic, we represent non-profit tax-exempt organizations that engage in real estate, economic, and community development. Some of our clients include Greater Cleveland Habitat for Humanity and Karamu House, which is a theater and community arts center. We serve as general counsel for some clients and provide legal advice on an as needed basis for others. The Clinic provides legal advice on real estate matters, corporate governance, transactions, and tax issues. The complexity of matters that we handle ranges from drafting a code of regulations to representing clients in large development projects such as a $5.1 million community center for seniors

Degenerations of ideal hyperbolic triangulations

Let M be a cusped 3-manifold, and let T be an ideal triangulation of M. The deformation variety D(T), a subset of which parameterises (incomplete) hyperbolic structures obtained on M using T, is defined and compactified by adding certain projective classes of transversely measured singular codimension-one foliations of M. This leads to a combinatorial and geometric variant of well-known constructions by Culler, Morgan and Shalen concerning the character variety of a 3-manifold.Comment: 31 pages, 11 figures; minor changes; to appear in Mathematische Zeitschrif
