    The effects of manufacturing and its consequent commerce upon the welfare of the immediate rural area

    It is a well known fact that Tennessee’s development of manufacturing on any extensive scale is of comparatively recent growth. The chief business of the people has been agriculture. The basis of commerce has been largely products of the soil. But there is every reason to believe that manufacturing and its consequent commerce will continue to grow; for with the improvement of farm machinery and the advancement of agricultural science the production per farmer has increased. This will release much labor for other enterprises. Then too, Tennessee is rich in mineral resources and water power. It is now being recognized as stated by Professor C. E. Allred, Professor of Agricultural Economies, University of Tennessee, in the preface to his bulletin “Economic and Social Study of Tennessee”, that “it is not necessary to leave economic and social progress to blind chance, but it is possible for a state or a region to set a definite goal and by the concerted action of all the agencies and people involved to carry the program to a successful conclusion. If evidence points toward a great industrial development of the state, and if we can by conscious effort direct this development of the state, and if we can by conscious effort direct this development in economic and social channels for the welfare of the entire state, it would seem logical for some agency to chart this course

    Heterogeneous Self-Reconfiguring Robotics: Ph.D. Thesis Proposal

    Self-reconfiguring robots are modular systems that can change shape, or reconfigure, to match structure to task. They comprise many small, discrete, often identical modules that connect together and that are minimally actuated. Global shape transformation is achieved by composing local motions. Systems with a single module type, known as homogeneous systems, gain fault tolerance, robustness and low production cost from module interchangeability. However, we are interested in heterogeneous systems, which include multiple types of modules such as those with sensors, batteries or wheels. We believe that heterogeneous systems offer the same benefits as homogeneous systems with the added ability to match not only structure to task, but also capability to task. Although significant results have been achieved in understanding homogeneous systems, research in heterogeneous systems is challenging as key algorithmic issues remain unexplored. We propose in this thesis to investigate questions in four main areas: 1) how to classify heterogeneous systems, 2) how to develop efficient heterogeneous reconfiguration algorithms with desired characteristics, 3) how to characterize the complexity of key algorithmic problems, and 4) how to apply these heterogeneous algorithms to perform useful new tasks in simulation and in the physical world. Our goal is to develop an algorithmic basis for heterogeneous systems. This has theoretical significance in that it addresses a major open problem in the field, and practical significance in providing self-reconfiguring robots with increased capabilities

    THE CINEMATIC COLLEGE PROFESSOR: CONCEPTIONS AND REPRESENTATIONS

    Get PDF
    Depictions of college professors in American films are common, and while a number of studies have investigated various aspects of college life in motion pictures, few have focused exclusively on the cinematic professoriate. In addition to being an indelible part of history, cinematic depictions of college professors are part of the national discourse on the role and function of the faculty and university. An investigation of how college professors have been represented in American films, and how these representations are read and created by real-life college professors and filmmakers may provide a deeper understanding of the relationship between popular culture images and academia. This project consists of three sections. The first focuses on the trajectories of negative representations of college professors in popular American films from 1970-2016. The second examines interview responses of film professors to on-screen depictions of college faculty. The third presents a case study of professorial depictions by a group of filmmakers who created a feature length film about a college professor. As various public stakeholders are increasingly questioning the role of the college professor and the institution of higher education, this project seeks to examine the influence of popular professor images and cultural influences on the conceptions of two interpretive communities – one that embodies the professoriate and one that creates images surrounding it. Moreover, this project considers these depictions within film marketplace and popular culture contexts

    Evidence of a structural anomaly at 14 K in polymerised CsC60

    Full text link
    We report the results of a high-resolution synchrotron X-ray powder diffraction study of polymerised CsC60_{60} in the temperature range 4 to 40 K. Its crystal structure is monoclinic (space group I2/m), isostructural with RbC60_{60}. Below 14 K, a spontaneous thermal contraction is observed along both the polymer chain axis, aa and the interchain separation along [111], d1d_1. This structural anomaly could trigger the occurrence of the spin-singlet ground state, observed by NMR at the same temperature.Comment: 8 pages, 5 figures, submitte
