The Middle Caddoan Period in East Texas: A Summary of the Findings of the East Texas Caddoan Research Group

The second meeting of the East Texas Caddoan Research Group (ETCRG) met in San Antonio on October 27, 1996, to consider the archaeology of the Middle Caddoan period in East Texas. The meeting was arranged as a three hour symposium held in conjunction with the annual meeting of the Texas Archeological Society. The meeting\u27s format involved the informal presentation by several ETCRG members of major research findings along thematic lines for each of several river basins in the region. The presenters distributed handouts to participants and mixed their comments with slides, photographs, and the hands-on examination of a few selected artifacts. The presentations and discussions were tape-recorded, and transcribed and edited proceedings of the meeting are to be published in a future volume of the Journal of Northeast Texas Archaeology. Brief periods of discussion did occur between the presenters, and the audience participated as well, during the three hour meeting; however, the general consensus of the group was that more time was needed and there was much left to be discussed. This paper attempts to summarize the information presented during the ETCRG meeting, and may (we think) represent a good starting place for continued dialog on the archeology of the Middle Caddoan period, as well as further dialog on the organization and arrangement of future ETCRG meetings. Eight handouts were available to the research group. Four were river basin archaeological summaries prepared by Maynard Cliff (the lower Sulphur River basin), Bo Nelson and Mike Turner (Cypress Creek Drainage basin), Tim Perttula and Brett Cruse (the upper and middle Sabine River basin), and Tom Middlebrook (Attoyac and Angelina River basins). Two handouts not associated with presentations were also prepared for the ETCRG members, namely archaeological summaries of the Middle Caddoan period by Tim Perttula for the middle Red River basin and the upper Sulphur River basin. Jim Corbin provided extensive information on the Middle Caddoan Washington Square Mound site (41NA49) in Nacogdoches County, while Bob Turner discussed archaeological materials found in three Middle Caddoan period cemeteries in Camp and Upshur counties

One Arizona: Evaluation Executive Brief

At a time when an extraordinary rhetoric of hate and intolerance defines our political climate, a narrative of fear towards newcomers threatens to divide us, and the Supreme Court is deadlocked on moving forward President Obama's Executive Actions on immigration, we are deeply moved and lifted up by the story of One Arizona. This is a story of a standout coalition of community partners that is transforming Arizona into a model for Latino civic engagement and political empowerment. Against the heated debate of building more walls along the southern border, One Arizona is a bright light and a reason for hope

Prehistoric Caddo Ceramics from the Henry Lake Site (41CE324), Cherokee County, Texas

This article discusses the character of the Caddo ceramics from a single component Frankston phase (ca. A.D. 1400-1650) occupation at the Henry Lake site (41CE324) in northwestern Cherokee County, Texas. This follows a brief discussion of the history of the site, and we conclude this article with a consideration of the temporal and cultural place of the site\u27s Caddo ceramic assemblage within the upper Neches River basin

An extended case study on the phenomenology of sequence-space synesthesia

Investigation of synesthesia phenomenology in adults is needed to constrain accounts of developmental trajectories of this trait. We report an extended phenomenological investigation of sequence-space synesthesia in a single case (AB). We used the Elicitation Interview (EI) method to facilitate repeated exploration of AB's synesthetic experience. During an EI the subject's attention is selectively guided by the interviewer in order to reveal precise details about the experience. Detailed analysis of the resulting 9 h of interview transcripts provided a comprehensive description of AB's synesthetic experience, including several novel observations. For example, we describe a specific spatial reference frame (a "mental room") in which AB's concurrents occur, and which overlays his perception of the real world (the "physical room"). AB is able to switch his attention voluntarily between this mental room and the physical room. Exemplifying the EI method, some of our observations were previously unknown even to AB. For example, AB initially reported to experience concurrents following visual presentation, yet we determined that in the majority of cases the concurrent followed an internal verbalization of the inducer, indicating an auditory component to sequence-space synesthesia. This finding is congruent with typical rehearsal of inducer sequences during development, implicating cross-modal interactions between auditory and visual systems in the genesis of this synesthetic form. To our knowledge, this paper describes the first application of an EI to synesthesia, and the first systematic longitudinal investigation of the first-person experience of synesthesia since the re-emergence of interest in this topic in the 1980's. These descriptions move beyond rudimentary graphical or spatial representations of the synesthetic spatial form, thereby providing new targets for neurobehavioral analysis

Low-temperature chemistry using the R-matrix method

Techniques for producing cold and ultracold molecules are enabling the study of chemical reactions and scattering at the quantum scattering limit, with only a few partial waves contributing to the incident channel, leading to the observation and even full control of state-to-state collisions in this regime. A new R-matrix formalism is presented for tackling problems involving low- and ultra-low energy collisions. This general formalism is particularly appropriate for slow collisions occurring on potential energy surfaces with deep wells. The many resonance states make such systems hard to treat theoretically but offer the best prospects for novel physics: resonances are already being widely used to control diatomic systems and should provide the route to steering ultracold reactions. Our R-matrix-based formalism builds on the progress made in variational calculations of molecular spectra by using these methods to provide wavefunctions for the whole system at short internuclear distances, (a regime known as the inner region). These wavefunctions are used to construct collision energy-dependent R-matrices which can then be propagated to give cross sections at each collision energy. The method is formulated for ultracold collision systems with differing numbers of atoms.Comment: Presented at Faraday Discussion on the Theory of Chemical Reactions Published in Faraday Discussion

Deep neutral hydrogen observations of Leo T with the Westerbork Synthesis Radio Telescope

Leo T is the lowest mass gas-rich galaxy currently known and studies of its gas content help us understand how such marginal galaxies survive and form stars. We present deep neutral hydrogen (HI) observations from the Westerbork Synthesis Radio Telescope in order to understand its HI distribution and potential for star formation. We find a larger HI line flux than the previously accepted value, resulting in a 50% larger HI mass of 4.1 x 10^5 Msun. The additional HI flux is from low surface brightness emission that was previously missed; with careful masking this emission can be recovered even in shallower data. We perform a Gaussian spectral decomposition to find a cool neutral medium component (CNM) with a mass of 3.7 x 10^4 Msun, or almost 10% of the total HI mass. Leo T has no HI emission extending from the main HI body, but there is evidence of interaction with the Milky Way circumgalactic medium in both a potential truncation of the HI body and the offset of the peak HI distribution from the optical center. The CNM component of Leo T is large when compared to other dwarf galaxies, even though Leo T is not currently forming stars and has a lower star formation efficiency than other gas-rich dwarf galaxies. However, the HI column density associated with the CNM component in Leo T is low. One possible explanation is the large CNM component is not related to star formation potential but rather a recent, transient phenomenon related to the interaction of Leo T with the Milky Way circumgalactic medium.Comment: accepted for publication in A&A; 12 pages, 13 figure

Low temperature scattering with the R-matrix method: argon-argon scattering

Results for elastic atom-atom scattering are obtained as a first practical application of RmatReact, a new code for generating high-accuracy scattering observables from potential energy curves. RmatReact has been created in response to new experimental methods which have paved the way for the routine production of ultracold atoms and molecules, and hence the experimental study of chemical reactions involving only a small number of partial waves. Elastic scattering between argon atoms is studied here. There is an unresolved discrepancy between different argon-argon potential energy curves which give different numbers of vibrational bound states and different scattering lengths for the argon-argon dimer. Depending on the number of bound states, the scattering length is either large and positive or large and negative. Scattering observables, specifically the scattering length, effective range, and partial and total cross-sections, are computed at low collision energies and compared to previous results. In general, good agreement is obtained, although our full scattering treatment yields resonances which are slightly lower in energy and narrower than previous determinations using the same potential energy curve.Comment: 26 pages, 9 figures, 3 table

Is Innovation King at the Antitrust Agencies? The Intellectual Property Guidelines Five Years Later

The Microsoft antitrust case focused public attention on the role of antitrust enforcement in preserving the forces of innovation in high-technology markets. Traditionally, regulators focused on whether companies artificially hiked prices or reduced output. Now, they're increasingly likely to look first at whether corporate behavior aids or impedes innovation. In this paper, we examine whether innovation has displaced short-term price effects as the focus of antitrust enforcement by the Department of Justice and the Federal Trade Commission and, to the extent that it has, whether enforcement actions are any different as a result. We also ask whether enforcement actions in the area of intellectual property and innovation have been consistent with the 1995 DOJ/FTC Antitrust Guidelines for the Licensing of Intellectual Property [IP Guidelines]. Finally, we consider whether recent enforcement actions identify key areas in which additional guidance from the Agencies would be desirable. We address these questions first in merger cases and then in non-merger cases.
