NASA Wallops Flight Center GEOS-3 altimeter data processing report

The procedures used to process the GEOS-3 radar altimeter data from raw telemetry data to a final user data product are described. In addition, the radar altimeter hardware design and operating parameters are presented to aid the altimeter user in understanding the altimeter data

Three methods of presenting flight vector information in a head-up display during simulated STOL approaches

A simulator study was conducted to determine the usefulness of adding flight path vector symbology to a head-up display designed to improve glide-slope tracking performance during steep 7.5 deg visual approaches in STOL aircraft. All displays included a fixed attitude symbol, a pitch- and roll-stabilized horizon bar, and a glide-slope reference bar parallel to and 7.5 deg below the horizon bar. The displays differed with respect to the flight-path marker (FPM) symbol: display 1 had no FPM symbol; display 2 had an air-referenced FPM, and display 3 had a ground-referenced FPM. No differences between displays 1 and 2 were found on any of the performance measures. Display 3 was found to decrease height error in the early part of the approach and to reduce descent rate variation over the entire approach. Two measures of workload did not indicate any differences between the displays

„Entartete“ Musik im Dritten Reich und die Politisierung von (Pop)Musik in der aktuellen amerikanischen Kultur

Welcher Musiker als kulturell-wertvoll aufgefasst wird, wird von der Mainstreamgesellschaft, auf der Basis kolonialer ‘Rassenhierarchien\u27 festgelegt. Hauptsächlich ‘reinweiße’ Musiker sind als Musiker Teil einer ‘höheren Rassenhierarchie’. Diese ‘Rassenhierarchie’ wird sowohl von der Mainstreamgesellschaft als auch von Rechtsextremisten geschätzt. Allerdings geschieht dies in einem deutlicheren und auch offenerem Maße bei Rechtsextremisten

Review of 'Speaking Out: Stopping Homophobic and Transphobic Abuse In Queensland'

Speaking Out documents the outcomes of the largest ever study to examine homophobic and transphobic abuse and reporting in Queensland, Australia. It reports the results of a quantitative survey on victimisation of lesbian, gay, bisexual, transgender, intersex, and queer (LGBTIQ) people and how this victimisation is reported to police. Follow-up qualitative interviews and focus groups were also conducted with LGBTIQ people to examine the impact of this abuse and the reporting to police. This research is timely as we can sometimes assume LGBTIQ victimisation is a historical problem and may be settled by the idea that relations with police are in good shape. This book clearly demonstrates that we have some way to go before we can be assured these issues have been resolved..

Long-term impacts of disturbance on nitrogen-cycling bacteria in a New England salt marsh

Recent studies on the impacts of disturbance on microbial communities indicate communities show differential responses to disturbance, yet our understanding of how different microbial communities may respond to and recover from disturbance is still rudimentary. We investigated impacts of tidal restriction followed by tidal restoration on abundance and diversity of denitrifying bacteria, ammonia-oxidizing bacteria (AOB), and ammonia-oxidizing archaea (AOA) in New England salt marshes by analyzing nirS and bacterial and archaeal amoA genes, respectively. TRFLP analysis of nirS and betaproteobacterial amoA genes revealed significant differences between restored and undisturbed marshes, with the greatest differences detected in deeper sediments. Additionally, community patterns indicated a potential recovery trajectory for denitrifiers. Analysis of archaeal amoA genes, however, revealed no differences in community composition between restored and undisturbed marshes, but we detected significantly higher gene abundance in deeper sediment at restored sites. Abundances of nirS and betaproteobacterial amoA genes were also significantly greater in deeper sediments at restored sites. Porewater ammonium was significantly higher at depth in restored sediments compared to undisturbed sediments, suggesting a possible mechanism driving some of the community differences. Our results suggest that impacts of disturbance on denitrifying and ammonia-oxidizing communities remain nearly 30 years after restoration, potentially impacting nitrogen-cycling processes in the marsh. We also present data suggesting that sampling deeper in sediments may be critical for detecting disturbance effects in coastal sediments

Taking Positive Steps

In antiquity the Oracle at Delphi urged each to know thyself. Socrates followed with the observation that The unexamined life is not worth living. Aristotle called for a balance in creating the good life centering on the golden mean. In the second century A.D. Marcus Aurelius, emperor of the Roman empire (the closest the western world may have ever come to a philosopher king), reminded himself in his Meditations that, We are troubled not by the things of the world but, rather, by our perception of those things. Much more recently philosopher William James stated something similar by suggesting that the most important discovery in psychology of his day is that by changing the interior states of our minds, we can change the exterior dimensions of our lives. And, of course, Norman Vincent Peale influenced millions through The Power of Positive Thinking

Alternative Tourism and Development: Implications for International Study Abroad and Volunteer Programs in the Global South

Recent years have seen rising interest among Western travelers in the so-called “Global South” or “developing world,” especially through experiences that fall under the umbrella term of “alternative tourism.” Many travelers engage in this type of tourism through experiences in either one or both of alternative tourism’s most popular sub-genres: alternative study abroad and volunteer tourism. With many of these programs either implicitly or explicitly geared toward development, this paper discusses the possible development-related consequences upon the places in which they operate. It traces origins and causes of alternative tourism’s rise, and explains how it has come to be associated with development. Finally, it identifies two exemplary programs that could be considered models for how to use study abroad and volunteer tourism to achieve development and positive transformation for both travelers and the communities they visit

A computer program for the calculation of laminar and turbulent boundary layer flows

The results are presented of a study to produce a computer program to calculate laminar and turbulent boundary layer flows. The program is capable of calculating the following types of flow: (1) incompressible or compressible, (2) two dimensional or axisymmetric, and (3) flows with significant transverse curvature. Also, the program can handle a large variety of boundary conditions, such as blowing or suction, arbitrary temperature distributions and arbitrary wall heat fluxes. The program has been specialized to the calculation of equilibrium air flows and all of the thermodynamic and transport properties used are for air. For the turbulent transport properties, the eddy viscosity approach has been used. Although the eddy viscosity models are semi-empirical, the model employed in the program has corrections for pressure gradients, suction and blowing and compressibility. The basic method of approach is to put the equations of motion into a finite difference form and then solve them by use of a digital computer. The program is written in FORTRAN 4 and requires small amounts of computer time on most scientific machines. For example, most laminar flows can be calculated in less than one minute of machine time, while turbulent flows usually require three or four minutes

Changing Behaviors to Build Better Physician/Patient Relationships

Health care literature is bursting with commentary about patient rights, patient expectations, patient demands, patient welfare, patient safety, patient privacy, informed consent and quality of care. Why are these topics of concern? Why can\u27t we just take it for granted that the patient and the patient\u27s interest come first in the business of health care? Obviously, we cannot take it for granted. But the reasons why we can\u27t are not too obvious - and neither are the remedies
