Initial Findings from the Archeological Investigations of the Hardin A Site (41GG69), Gregg County, Texas

The Hardin A site (41GG69) is a prehistoric Caddo Indian settlement located on a high terrace overlooking the Sabine River flood-plain in Gregg County, Texas. The modem channel of the river is about 650 m to the south, and there is a small, intermittent tributary ca. 180 m to the west. The senior author discovered the Hardin A site in 1997, after he was told about it by informants who were looting a midden and cemetery area, and he formally recorded it in February 2000. In an effort to better understand the temporal and archeological context of the prehistoric Caddo occupation at the Hardin A site, limited hand excavations (Unit 1, a l x 2 m unit) were completed in the midden area by the senior author, with the assistance of Mark Walters, Texas Archeological Steward, in the spring of 2000. That work exposed deep (+90 cm) archeological deposits in a sandy loam soil with some preserved midden, as well as part of a pit feature in the northern and eastern part of the unit. The pit feature extended to approximately 160 cm below surface (bs), and contained dark brown to very dark grayish-brown fill with large amounts of ceramics (including about 50 decorated sherds), animal bone, and charred plant remains (especially hickory nutshells). Analyses are ongoing on these remains. In this paper, we discuss the results of our radiocarbon and oxidizable carbon ratio (OCR) studies in the Hardin A midden

A qualitative exploration of the experiences of palliative care staff when working with death and dying

Section A provides a review of the literature of the experience of staff working in palliative care. The review summarises, critiques, and synthesises fourteen papers matching the inclusion and quality criteria. Papers are reviewed in light of their methodological strengths and limitations. Thematic synthesis of the findings yielded four key themes, and clinical and research implications are discussed. Section B describes a qualitative study that explores palliative care nurses’ experience of interpersonal challenges with dying patients. Seven semi-structured interviews were conducted and analysed using Interpretative Phenomenological Analysis and psychodynamic exploration. Three superordinate themes and related subthemes are described and discussed. Limitations and clinical and research implications for future research are outlined. Section C provides supporting documentatio

Remarks on Form Factor Bounds

Improved model independent upper bounds on the weak transition form factors are derived using inclusive sum rules. Comparison of the new bounds with the old ones is made for the form factors h_{A_1} and h_V in B -> D* decays.Comment: 8 pages, 2 figures, title changed and typos corrected for journal publicatio
