Additional Lake Bob Sandlin Sites with Documented Collections of Prehistoric Lithic and Ceramic Artifacts

This is the third in a series of publications that concern the documentation of prehistoric artifact-collections from sites found along the shoreline of Lake Bob Sandlin in the Big Cypress Creek basin of East Texas. These documentation efforts have demonstrated that sites at the lake have diverse temporal and spatial patterns, with an intensive Caddo occupation from the Middle (ca. A.D. 1200-1425) to Late Caddo (ca. A.D. 1430-1680) periods

The Ceramic Sherd Assemblage from the C. D. Marsh Site (41HS269) in Harrison County, Texas

The C. D. Marsh site (41HS269) is an ancestral Caddo settlement and cemetery on Eight Mile Creek, a southwestward–flowing tributary to the Sabine River in southeastern Harrison County, Texas. It is on an alluvial terrace about 1.6 km from the confluence of Eight Mile Creek and the Sabine River. Buddy Calvin Jones discovered the site in January 1958, and he estimated that the habitation area covered ca. 1–2 acres, with substantial midden deposits. Jones collected a substantial sample of plain and decorated ceramic vessel sherds (n=1736) from the habitation deposits (Jones 1968:96), in addition to a number of ceramic vessels and other funerary offerings from Caddo burial features. A subset of this reported sherd assemblage has been identified in the collections of the Gregg County Historical Museum, and the 2015 analysis of that sherd sample is the subject of this article

Inheritance of Flower Color in Musk Thistle (\u3ci\u3eCarduus thoermeri\u3c/i\u3e)

Four flower-color phenotypes were observed in a population of musk thistle (Carduus tboermeri Weinm.). This plant has been commonly referred to as C. nutans L. The four phenotypes were: purple corolla and purple pollen, pink corolla and white pollen, white corolla and purple pollen, and white corolla and white pollen. In four generations, 177 self-pollinated individuals of these four phenotypes produced 2123 progeny plants that were classified. Results support the hypothesis that three independent gene pairs were involved in deter- mining the four flower phenotypes. The gene pairs have been designated P/p, W/w, and Pi/pi. It was postulated that all three dominant alleles, P, W, and Pi, must be present to produce both purple corollas and purple pollen. The p allele prevents color development in both corollas and pollen; the w allele eliminates color in corollas but does not affect pollen color; and the pi allele dilutes corolla color from purple to pink and eliminates pollen color. Height measurements of progenies of self-pollinated plants indicated that decreased plant height was associated with inbreeding. On the basis of the evidence presented, the musk thistle plants used in these experiments appear to belong to a single species

Colonialism and Male Domestic Service Across the Asia Pacific

Examining the role of Asian and indigenous male servants across the Asia Pacific from the late-19th century to the 1930s, this study shows how their ubiquitous presence in these purportedly \u27humble\u27 jobs gave them a degree of cultural influence that has been largely overlooked in the literature on labour mobility in the age of empire. With case studies from British Hong Kong, Singapore, Northern Australia, Fiji and British Columbia, French Indochina, the American Philippines and the Dutch East Indies, the book delves into the intimate and often conflicted relationships between European and American colonists and their servants. It explores the lives of \u27houseboys\u27, cooks and gardeners in the colonial home, considers the bell-boys and waiters in the grand colonial hotels, and follows the stewards and cabin-boys on steamships travelling across the Indian and Pacific Oceans. This broad conception of service allows Colonialism and Male Domestic Service across Asia and the Pacific to illuminate trans-colonial or cross-border influences through the mobility of servants and their employers. This path-breaking study is an important book for students and scholars of colonialism, labour history and the Asia Pacific region

Cytochromes and the Succinic Acid Oxidase System of Poky Strains of Neurospora

Recent investigations in this laboratory (1) have demonstrated that in Neurospora crassa growth characteristics representing at least two stable states are possible with the same constitution of nuclear genes. If a slow growing strain, designated poky, functions in a cross to wild type as the maternal or protoperithecial parent, then all progeny from the cross exhibit the poky character. If the cross is made in the reverse, or reciprocal manner, that is, with the wild type strain functioning as a protoperithecial parent, then all progeny are normal in growth rate. During the course of the work on inheritance it was observed that mycelial pads from poky were characterized by a red color reminiscent of that of the heme pigments. Examinations of suspensions and extracts of the mold with a spectroscope yielded the information that poky mycelium contains large quantities of a substance having the absorption spectrum characteristic of cytochrome c, whereas the bands corresponding to cytochromes o and b were not visible. All three of these components were detected easily in the wild type strain. The experimental results presented here provide more precise information on the similarities and differences between these two strains with respect to the cytochrome and the succinic acid oxidase systems. Preliminary observations suggested that poky in Neurospora is analogous to petite in yeast (2) in which abnormalities in the succinic acid oxidase system have been reported, but this analogy is shown here to be only a partial one

Special Lagrangian cones with higher genus links

For every odd natural number g=2d+1 we prove the existence of a countably infinite family of special Lagrangian cones in C^3 over a closed Riemann surface of genus g, using a geometric PDE gluing method.Comment: 48 page

The Effects of Grace Interventions in Church Communities

Grace remains little studied though several recent studies have developed promising ways to measure grace. Here we report two studies involving grace interventions as part of an ongoing investigation of positive psychology in the context of Christian church communities, Study One used a crossover design in which two congregations were measured on grace and other variables at the outset, and again after phases one and two. One congregation received a grace intervention during phase one and the second during phase two. Results showed increased scores on grace but not an expected increase in marital satisfaction among married participants. Study Two used a similar design with two additional congregations to assess effects of a grace intervention on selfforgiveness. As expected, congregants receiving the grace intervention showed increases in trait self-forgiveness when compared to those in the wait-list
