C-SPAN is the network of record for US political affairs, broadcasting live gavel-to-gavel proceedings of the House of Representatives and the Senate, and to other forums where public policy is discussed, debated, and decided--without editing, commentary, or analysis and with a balanced presentation of points of view. The C-SPAN Archives, located adjacent to Purdue University, is the home of the online C-SPAN Video Library. The Archives has recorded all of C-SPAN's television content since 1987. Extensive indexing, captioning, and other enhanced online features provide researchers, policy analysts, students, teachers, and public officials with an unparalleled chronological and internally cross-referenced record for deeper study. Books in this series present the finest interdisciplinary research utilizing tools of the C-SPAN Video Library. Each volume highlights recent scholarship and comprises leading experts and emerging voices in political science, journalism, psychology, computer science, communication, and a variety of other disciplines. Each section within each volume includes responses from expert discussants. Developed in partnership with the Center for C-SPAN Scholarship & Engagement in the Purdue University Brian Lamb School of Communication with support from the C-SPAN Education Foundation, this volume is guided by the ideal that research based on C-SPAN video can increase our understanding of American politics and democracy based on the ideals of our American experiment. The fifth volume of the C-SPAN Archives research focuses primarily on the Trump presidency in the first term. Chapters address his moral language, his rhetoric on climate change, and African American support for Trump. Other chapters use the C-SPAN Archives to study congressional influence on immigration policy, nonverbal cues in congressional speeches, and local and national perspectives on congressional debates.

The object of this review is to summarize the achievements of research on the Alcator C-Mod tokamak [Hutchinson et al., Phys. Plasmas 1, 1511 (1994) and Marmar, Fusion Sci. Technol. 51, 261 (2007)] and to place that research in the context of the quest for practical fusion energy. C-Mod is a compact, high-field tokamak, whose unique design and operating parameters have produced a wealth of new and important results since it began operation in 1993, contributing data that extends tests of critical physical models into new parameter ranges and into new regimes. Using only high-power radio frequency (RF) waves for heating and current drive with innovative launching structures, C-Mod operates routinely at reactor level power densities and achieves plasma pressures higher than any other toroidal confinement device. C-Mod spearheaded the development of the vertical-target divertor and has always operated with high-Z metal plasma facing components—approaches subsequently adopted for ITER. C-Mod has made ground-breaking discoveries in divertor physics and plasma-material interactions at reactor-like power and particle fluxes and elucidated the critical role of cross-field transport in divertor operation, edge flows and the tokamak density limit. C-Mod developed the I-mode and the Enhanced Dα H-mode regimes, which have high performance without large edge localized modes and with pedestal transport self-regulated by short-wavelength electromagnetic waves. C-Mod has carried out pioneering studies of intrinsic rotation and demonstrated that self-generated flow shear can be strong enough in some cases to significantly modify transport. C-Mod made the first quantitative link between the pedestal temperature and the H-mode's performance, showing that the observed self-similar temperature profiles were consistent with critical-gradient-length theories and followed up with quantitative tests of nonlinear gyrokinetic models. RF research highlights include direct experimental observation of ion cyclotron range of frequency (ICRF) mode-conversion, ICRF flow drive, demonstration of lower-hybrid current drive at ITER-like densities and fields and, using a set of novel diagnostics, extensive validation of advanced RF codes. Disruption studies on C-Mod provided the first observation of non-axisymmetric halo currents and non-axisymmetric radiation in mitigated disruptions. A summary of important achievements and discoveries are included. ; United States. Dept. of Energy (Cooperative Agreement DE-FC02-99ER54512) ; United States.

While disaggregation has gained prominence in policy research, it is sometimes flawed by invalid & unreliable policy measures, & by improper inferences derived from policy data. Examples of research of several types are compared, including studies which disaggregate within a level of analysis, between levels of analysis, or within a level of analysis with interlevel inferences. Reviewed are both the usefulness of disaggregation & the errors which it may generate. 1 Table. Modified HA.

This department is devoted to shorter articles and notes on research in the communications field, either completed or in progress. Readers are invited to submit reports on investigative studies which might prove useful to other students because of content, method, or implications for further research.

Research facilities in Lebanon are excellent and the research climate, as of June 1972, was fairly good. Lebanon continues to fulfill its historic function as a meeting place for Western and Arab culture. But the same political factors that are alienating the Arab world as a whole from the Anglo-Saxon community, notably the Arab-Israeli conflict, inevitably threaten this liberal research climate. There are vocal and influential elements of Lebanese opinion which feel that American imperialism harnesses even the scholarly community for its exploitative ends. Lebanon has had no Camelot scandal so far, but the American University of Beirut was once forced to cancel a project supported by the U.S. Department of Defense. Under these circumstances it is always possible that an innocent researcher could accidentally create a crisis that would jeopardize research conditions. Thus, it may not be out of place to suggest that visiting scholars should make special efforts to be prudent, candid, courteous and patient in their research work. It is desirable to have at least one reputable Lebanese friend who will be willing to advise and if necessary endorse the research project. It is not necessary that a local institution formally sponsor a project, but some kind of local association can be useful both in assisting the research itself and in avoiding troubles. Graduate students doing field research should definitely have some local advisor or patron.
