Compilation of an anthology of concert band scores for study by conducting students.
The purpose of this project is to give a detailed description of the process involved in developing an anthology of excerpts from musical scores. The scope of the final project will encompass works for concert band and is intended for use as a study guide for advanced undergraduate and graduate conducting students. This. paper details the methods used for selecting compositions to be considered for inclusion, the final selection process for inclusion, relevant observations made during these processes, and the format of the completed anthology. The selection process took place in two parts. The first part involved soliciting suggestions for inclusion from a small group of nationally known college and university band directors, analyzing their responses, and constructing a survey to be given to a larger group of college and university music educators and band directors. The next phase of the project involved selecting the survey group, analyzing their responses, and compiling the list of compositions to be used in the final project. The final analysis of the results from the second survey showed a consensus of opinion with regard to compositions that should be included in this type of work
A comparison of head and manual control for a position-control pursuit tracking task
Head control was compared with manual control in a pursuit tracking task involving proportional controlled-element dynamics. An integrated control/display system was used to explore tracking effectiveness in horizontal and vertical axes tracked singly and concurrently. Compared with manual tracking, head tracking resulted in a 50 percent greater rms error score, lower pilot gain, greater high-frequency phase lag and greater low-frequency remnant. These differences were statistically significant, but differences between horizontal- and vertical-axis tracking and between 1- and 2-axis tracking were generally small and not highly significant. Manual tracking results were matched with the optimal control model using pilot-related parameters typical of those found in previous manual control studies. Head tracking performance was predicted with good accuracy using the manual tracking model plus a model for head/neck response dynamics obtained from the literature
Adaptive Transmission Techniques for Mobile Satellite Links
Adapting the transmission rate in an LMS channel is a challenging task
because of the relatively fast time variations, of the long delays involved,
and of the difficulty in mapping the parameters of a time-varying channel into
communication performance. In this paper, we propose two strategies for dealing
with these impairments, namely, multi-layer coding (MLC) in the forward link,
and open-loop adaptation in the return link. Both strategies rely on
physical-layer abstraction tools for predicting the link performance. We will
show that, in both cases, it is possible to increase the average spectral
efficiency while at the same time keeping the outage probability under a given
threshold. To do so, the forward link strategy will rely on introducing some
latency in the data stream by using retransmissions. The return link, on the
other hand, will rely on a statistical characterization of a physical-layer
abstraction measure.Comment: Presented at the 30th AIAA International Communications Satellite

Commercialization of the land remote sensing system: An examination of mechanisms and issues
In September 1982 the Secretary of Commerce was authorized (by Title II of H.R. 5890 of the 97th Congress) to plan and provide for the management and operation of the civil land remote sensing satellite systems, to provide for user fees, and to plan for the transfer of the ownership and operation of future civil operational land remote sensing satellite systems to the private sector. As part of the planning for transfer, a number of approaches were to be compared including wholly private ownership and operation of the system by an entity competitively selected, mixed government/private ownership and operation, and a legislatively-chartered privately-owned corporation. The results of an analysis and comparison of a limited number of financial and organizational approaches for either transfer of the ownership and operation of the civil operational land remote sensing program to the private sector or government retention are presented
Re-thinking immigrant investment funds
WP-16-128The idea of selling membership into society is not new, but it has taken on new life with the recent proliferation globally of Immigrant Investor Programs (IIPs). These programs involve the sale of national membership privileges to wealthy foreigners. They are justified by attractive policy objectives: to stimulate economic development and attract engaged investor-migrants. But they are often plagued by failures to achieve either of these two goals. This paper surveys the universe of IIPs, reviews their objectives, activities and performance, and explores how they might be improved. We develop a two-dimensional typology for distinguishing IIPs according to types of criteria they impose on program applicants: (i) wealth criteria and (ii) engagement criteria. We map out four distinct immigrant investor strategies that emerge out of these different IIP criteria: Aspiring Astronauts, Absent Oligarchs, Migrant Mayors and Pioneer Patrons. By analyzing which IIP criteria encourage which strategies, we highlight common mismatches between stated objectives and embedded incentives, helping to explain why many IIPs report poor economic and immigration policy outcomes. We also contemplate solutions. In particular, we observe that the success of an IIP depends upon the coming-together of expertise from two domains—migration policy and investment management—and we draw upon insights from successful Sovereign Development Funds (SDFs), which likewise must simultaneously achieve public policy and financial goals. We propose a set of principles to guide the emergence of a new type of SDF: Immigrant Investment Funds (IIFs). We also indicate how such vehicles might help address urgent issues around migration and refugees, for example by investing in refugee and migrant entrepreneurship and in the infrastructures needed to incorporate newcomers, thereby demonstrating the public value of immigration at a time when anti-immigrant rhetoric has become a serious irritant in world politics.Alan Gamlen, Christopher Kutarna and Ashby Mon

Background: Without appropriate dissemination efforts, important research findings may remain solely in academic journals and never reach the public. Grounded in a social justice perspective, we argue that family scientists are and should be on the frontlines of direct social change and activities related to broader impacts. Method: In this call-to-action, we articulate the utility and praxis of public scholarship, or the production and dissemination of scientific knowledge for and with communities to create social change for the public good. Results: When engaging in public scholarship, we can build community trust, increase our impact and demonstrate the relevance of family science. Therefore, we offer practical suggestions like collaborating with individuals who serve in complementary roles, hosting a research press conference to disseminate key findings, and writing for local outlets like community newspapers. We also provide insights to help implement (e.g., resources for developing press releases, infographics or visual abstracts) and document (e.g., in promotion and tenure materials) these activities. Conclusion: We encourage scholars to keep these suggestions in mind when trying to think of creative broader impacts activities that illustrate the relevance of research in people's lives. Implications: By shifting academic cultures and engaging in public scholarship, family scholars can increase their reach and contribute to the enfranchisement of marginalized populations, while also enhancing the visibility of findings, building their scholarly networks, and growing public support for family science
