Plant Remains from Shelby Mound (41CP71), Camp County, Texas

Nine lots of botanical samples collected during 1988 and 1992 excavations at the Shelby Mound site (41CP71) were submitted for identification prior to their eventual curation at Stephen F. Austin State University. Some botanical samples from these excavations have been previously reported. Excavations at Shelby Mound were conducted in a 10 x 10 ft. unit divided into four 5 x 5 ft. squares. Botanical samples were recovered using 1/4-inch screen. Shelby Mound, also known as the Tracy site and the Greasy Creek site, is a large Late Caddo village, community cemetery, and mound center. Most of the community cemetery at the site was destroyed by looters more than 30 years ago

Potential commercial uses of EOS remote sensing products

The instrument complement of the Earth Observing System (EOS) satellite system will generate data sets with potential interest to a variety of users who are now just beginning to develop geographic information systems tailored to their special applications and/or jurisdictions. Other users may be looking for a unique product that enhances competitive position. The generally distributed products from EOS will require additional value added processing to derive the unique products desired by specific users. Entrepreneurs have an opportunity to create these proprietary level 4 products from the EOS data sets. Specific instruments or collections of instruments could provide information for crop futures trading, mineral exploration, television and printed medium news products, regional and local government land management and planning, digital map directories, products for third world users, ocean fishing fleet probability of harvest forecasts, and other areas not even imagined at this time. The projected level 3 product are examined that will be available at launch from EOS instruments and commercial uses of the data after value added processing is estimated

A fast semi-direct least squares algorithm for hierarchically block separable matrices

We present a fast algorithm for linear least squares problems governed by hierarchically block separable (HBS) matrices. Such matrices are generally dense but data-sparse and can describe many important operators including those derived from asymptotically smooth radial kernels that are not too oscillatory. The algorithm is based on a recursive skeletonization procedure that exposes this sparsity and solves the dense least squares problem as a larger, equality-constrained, sparse one. It relies on a sparse QR factorization coupled with iterative weighted least squares methods. In essence, our scheme consists of a direct component, comprised of matrix compression and factorization, followed by an iterative component to enforce certain equality constraints. At most two iterations are typically required for problems that are not too ill-conditioned. For an $M \times N$ HBS matrix with $M \geq N$ having bounded off-diagonal block rank, the algorithm has optimal $\mathcal{O} (M + N)$ complexity. If the rank increases with the spatial dimension as is common for operators that are singular at the origin, then this becomes $\mathcal{O} (M + N)$ in 1D, $\mathcal{O} (M + N^{3/2})$ in 2D, and $\mathcal{O} (M + N^{2})$ in 3D. We illustrate the performance of the method on both over- and underdetermined systems in a variety of settings, with an emphasis on radial basis function approximation and efficient updating and downdating.Comment: 24 pages, 8 figures, 6 tables; to appear in SIAM J.

A State’s Gendered Response to Political Instability: Gendering Labor Policy in Semi-Authoritarian El Salvador (1944-1972)

Unlike much of the gender and welfare literature, this study examines why a regime that constrains pressure from below would adopt gendered social policies. The Salvadoran case (1944-1972) suggests that political instability rather than societal pressures may prompt semi-authoritarian regimes to adopt gendered labor reforms. We extend the motivations for adopting gendered labor reforms to include co-opting labor by examining gendered labor reforms in the context of El Salvador’s historically contingent labor strategy. This gendered analysis helps explain how a semi-authoritarian regime secured political stability and reveals the special appeal gendered labor reforms may have to semi-authoritarian regimes

Psychological types of bilingual and monolingual female undergraduate students in Wales

The aim of this study was to complete the psychological type profiles of bilingual (fluent Welsh speakers) and monolingual (nonWelsh-speakers) students in Wales. The Myers-Briggs Type Indicator® instrument was completed by 425 female undergraduate students attending a university-sector college in Wales that exercises a bilingual policy (English and Welsh). From the total sample, 102 subjects identified themselves as fluent Welsh-speakers (bilinguals) and 101 as nonWelsh-speakers (monolinguals). The remaining 222 were Welsh learners and were excluded from the analyses of the present study. SRTT analyses revealed that in the study sample, the bilingual students demonstrated significantly more frequent preferences for Extraversion and for Sensing compared with the monolingual students
