Technology benefits and ground test facilities for high-speed civil transport development

The advanced technology base necessary for successful twenty-first century High-Speed Civil Transport (HSCT) aircraft will require extensive ground testing in aerodynamics, propulsion, acoustics, structures, materials, and other disciplines. This paper analyzes the benefits of advanced technology application to HSCT concepts, addresses the adequacy of existing groundbased test facilities, and explores the need for new facilities required to support HSCT development. A substantial amount of HSCT-related ground testing can be accomplished in existing facilities. The HSCT development effort could also benefit significantly from some new facilities initially conceived for testing in other aeronautical research areas. A new structures testing facility is identified as critically needed to insure timely technology maturation

T-odd correlations in charged Kl4 decays

We analyse the sensitivity to physics beyond the SM of T-odd correlations in $K_{\ell 4}$ decays, which do not involve the lepton polarization. We show that a combined analysis of $K^+_{\mu 4}$ and $K^-_{\mu 4}$ decays can lead to new constraints about CP violation in $\Delta S=1$ charged-current interactions, complementary to those obtained from the transverse muon polarization in $K_{\mu 3}$ and of comparable accuracy.Comment: 6 pages (LaTeX

Place-Based Initiatives: Lessons From Five Decades of Experimentation and Experience

This article summarizes the findings from a yearlong inquiry into the state of place-based initiatives, underscores the lessons learned, and develops implications for foundation practice. Place-based approaches have matured in response to five decades of historical change. In more recent years, a new framework for such initiatives has emerged that views place as an open system where neighborhoods are aligned with larger areas and influenced by market forces and public policy. Consequently, place-based initiatives targeted to a specific neighborhood are only part of any solution. Seven key lessons emerged from this inquiry that animate a renewed sense of the possible as the next generation of place-based initiatives unfolds

Place-Based Initiatives in the Context of Public Policy and Markets: Moving to Higher Ground

This monograph is the culmination of a yearlong inquiry by The Center on Philanthropy and Public Policy at USC into place based work. It includes a 50-year evolution of place-based initiatives and a synthesis of the inquiry's conversations with dozens of the foremost practitioners and scholars in the field, many of whom have spent their entire careers working on major philanthropic initiatives or government efforts addressing geographically-concentrated poverty. Among the insights in the report: poor U.S. neighborhoods are not all the same; a single process will not reverse generations of poverty; and public policy must be "place-conscious." National thought leaders also strongly recommend that in order to be successful, anti-poverty initiatives must be "nested" within larger, mutually reinforcing public policies and connected to the market economy; and philanthropic, corporate, and public resources should be "braided" together to achieve scale and impact. It also includes an important statement about the significance of "place-based" strategy by The Honorable Henry Cisneros, former Secretary of the U.S. Department of Housing and Urban Development, along with an illustrative example from Dr. Robert K. Ross President and CEO of the California Endowment, which is in the midst of a ten-year, 14-site, $1 billion place-based campaign in California, and a dozen response essays from a variety of experts across a range of disciplines

Integrating invasion and disease in the risk assessment of live bird trade.

AimInternational trade in plants and animals generates significant economic benefits. It also leads to substantial unintended impacts when introduced species become invasive, causing environmental disturbance or transmitting diseases that affect people, livestock, other wildlife or the environment. Policy responses are usually only implemented after these species become established and damages are already incurred. International agreements to control trade are likewise usually based on selection of species with known impacts. We aim to further develop quantitative invasive species risk assessment for bird imports and extend the tool to explicitly address disease threats.LocationUnited States of America.MethodsWe use a two-step approach for rapid risk assessment based on the expected biological risks due to both the environmental and health impact of a potentially invasive wildlife species in trade. We assess establishment probability based on a model informed by historical observations and then construct a model of emerging infectious disease threat based on economic and ecological characteristics of the exporting country.ResultsWe illustrate how our rapid assessment tool can be used to identify high-priority species for regulation based on a combination of the threat they pose for becoming established and vectoring emerging infectious diseases.Main conclusionsOur approach can be executed for a species in a matter of days and is nested in an economic decision-making framework for determining whether the biological risk is justified by trade benefits

Adolescent Boys are at Risk for Body Image Dissatisfaction and Muscle Dysmorphia

Background and Purpose: Muscle Dysmorphia (MD) is characterized by extreme body dissatisfaction and a drive for muscularity that leads to compulsive behaviors to attain an ideal body shape. The primary purpose of this study was to assess the level of body image dissatisfaction (BID) among male adolescents (N = 149, mean age = 15.01 + 1.85 y and mean BMI = 23.26 + 5.01 kg/m2 ) and whether or not BID was correlated with behaviors associated with MD. A secondary purpose was to examine if a difference exists between athletes and non-athletes. Methods: The Eating Attitude Survey (EAS) was used to assess attitudes toward body weight and shape while the Muscle Dysmorphia Inventory (MDI) was used to assess the behavioral and psychological characteristics of MD. Results: This sample of male adolescents indicate some level of BID, which is also associated with overall higher scores for all subscales of the MDI, but especially the subscales relating to muscularity. Athletes in particular showed higher levels of BID and higher scores on the MDI. Conclusion: Individuals who work with adolescent boys should be aware that they can develop body dissatisfaction and may participate in compensatory behaviors that may be harmful to their overall health and development

The CP-violating asymmetry in \eta\to\pi^+ \pi^- e^+e^-

We study the CP-violating asymmetry {\cal A}_{\rm CP}, which arises, in \eta\to\pi^+\pi^- e^+e^-, from the angular correlation of the e^+ e^- and \pi^+\pi^- planes due to the interference between the magnetic and electric decay amplitudes. With the phenomenologically determined magnetic amplitude and branching ratio as input, the asymmetry, induced by the electric bremsstrahlung amplitude through the CP-violating decay \eta\to\pi^+\pi^-, and by an unconventional tensor type operator, has been estimated respectively. The upper bound of {\cal A}_{\rm CP} from the former is about 10^{-3}, and the asymmetry from the latter might be up to O(10^{-2}). One can therefore expect that this CP asymmetry would be an interesting CP-violating observable for the future precise measurements in the \eta factories.Comment: LaTeX, 6 pages.
