Rowland Clark and Dan Holdeman Site Human Skeletal Remains
The Rowland Clark site was occupied by Caddoan Indian groups from approximately A.D. 1300-1600+. Twenty one of the 39 burials recovered during the Museum of the Red River excavations were assigned to the earliest McCurtain phase occupation (ca. A.D. 1300-1450); 14 burials were ascribed to a later McCurtain occupation between ca. A.D. 1450 and 1600; four burials belonged to the final McCurtain occupation (ca. A.D. 1600+) of the site. Since infants and children were buried under house floors rather than in the cemetery area associated with each time period, their interment does not necessarily follow the assigned time period. Due to poor preservation and small sample sizes all burials were evaluated as a single Caddoan population.
The burials from the Dan Holdeman site were found in a mound and three cemetery areas located on a terrace adjacent to the Red River. Skeletons of 26 individuals were recovered. The remains of an additional 15 individuals could not be retrieved due to their poor preservation. The acidity of the soil at the site contributed to considerable disintegration of the bones, leaving all burials in fragmentary condition.
Three time periods are represented in the burials from the Dan Holdeman site. Burials 22, 23, and 25 were associated with a Formative Caddoan occupation (that Perino designated the Spiro Focus) dating about A.D. 1000. Interments corresponding with the Middle Caddoan Sanders Focus, dated about A.D. 1200, include Burials 1-20 and 24. One subadult, Burial 21, dates to the latter portion of the McCurtain phase (ca. A.D. 1650). The skeletal material that could not be retrieved represented individuals living during the Formative and Middle Caddoan occupations.
Since much of the data on the osteoarcheology of the Clark and Holdeman sites has been presented in Loveland, specifically stature estimates, skeletal anomalies, and caries rates, it is the purpose of this appendix to summarize other aspects of the skeletal biology of the prehistoric inhabitants of the two sites. However, the poor condition of the skeletons recovered from the sites precludes accurately assessing the biological condition and adaptive efficiency of the people who lived at the site. However, the analyses presented here, and in Loveland, present data that provides a fairly complete picture of Caddoan adaptive efficiency on the Red River in Northeast Texas
Bilateral Variation in Man: Handedness, Handclasping, Armfolding and Mid-Phalangeal Hair
A study of bilateral variation among individuals from three populations was conducted. One sample consisted of 174 Cashinahua Indians who reside along the Curanja River in the Peruvian rain forest. A second group was composed of 286 students from anthropology classes at the University of Tennessee, Knoxville. Eighty-six families, including 372 individuals, constituted the third sample.
Four laterality traits - handedness, armfolding, handclasping, and mid-phalangeal hair - were analyzed by population and by individual family.
The most interesting variation occurred in the frequency of right and left handclasping and in the presence or absence of mid-phalangeal hair. The percentage of left and right armfolders among the populations was fairly stable. Handclasping and armfolding do not seem to be related to handedness, however, conflicting data on the relationship between armfolding and handclasping showed that further study is needed.
The Cashinahua differed more from the two Tennessee populations than the latter two did from each other. In particular, the frequency of mid-digital hair among the Cashinahua was very low, which is consistent with data from other American Indian groups. The two Tennessee populations, on the other hand, compared with other Caucasoid samples in hair frequency.
Analysis of the family data provided some evidence for the heritable character of the handclasping trait and strong evidence for the heritability of the mid-phalangeal hair trait. Armfolding and handedness, on the other hand, did not seem to reflect a strong genetic character
The Rowland Clark (41RR77) Site, Red River County, Texas : Editor\u27s Introduction
The Rowland Clark (41RR77) and Dan Holdeman (41RR11) archaeological sites were excavated in the late 1970s and early 1980s by Gregory Perino of the Museum of Red River in Idabel, Oklahoma. Manuscripts on those investigations were prepared by Perino shortly after the conclusion of the work, but these were never published, remaining instead on file at the Museum of the Red River
Health Behavior: Evolution of Two Paradigms
Public health nursing is a synthesis of professional nursing and public health science. To assist people effectively to determine and enhance their health capabilities, it is essential that public health nurses have a sound understanding of the behaviors that improve or jeopardize health. This concern arises from the profession's increased emphasis on health behavior and from nursing's stated goal of health promotion. To examine the topic from the perspectives of public health and professional nursing, we examine several issues related to the concept and its definition. We hope that the discussion will stimulate analysis both to clarify the concept and to contribute to the development of public health nursing science.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73194/1/j.1525-1446.1986.tb00474.x.pd
Really Underage Drinkers: Alcohol Use Among Elementary Students
Despite the current societal concern with underage drinking, little attention has been paid to alcohol use within the preadolescent population. This article presents the proceedings of a symposium held at the 2003 Research Society on Alcoholism meeting in Fort Lauderdale, Florida, that was organized and chaired by John E. Donovan. The intent of the symposium was to kick start research on alcohol use among elementary school children by reviewing what is known regarding drinking in childhood. Presentations included (1) The Epidemiology of Children's Alcohol Use, by John E. Donovan; (2) The Validity of Children's Self-Reports of Alcohol Use, by Sharon L. Leech; (3) Predicting Onset of Drinking From Behavior at Three Years of Age: Influence of Early Child Expectancies and Parental Alcohol Involvement Upon Early First Use, by Robert A. Zucker; and (4) Parent, Peer, and Child Risk Factors for Alcohol Use in Two Cohorts of Elementary School Children, by Carol J. Loveland-Cherry. Presentations indicated the need for better nationwide surveillance of children's experience with alcohol; suggested that children's reports of their use of alcohol tend to be reliable and valid; supported children's alcohol use schemas and parental drinking and alcoholism at child age three as independent predictors of early onset drinking; and showed that onset of drinking before fourth or fifth grade, peer pressure, and parental norms and monitoring predict elementary student alcohol use and misuse.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65944/1/01.ALC.0000113922.77569.4E.pd
Consensus coding sequence (CCDS) database: a standardized set of human and mouse protein-coding regions supported by expert curation.
The Consensus Coding Sequence (CCDS) project provides a dataset of protein-coding regions that are identically annotated on the human and mouse reference genome assembly in genome annotations produced independently by NCBI and the Ensembl group at EMBL-EBI. This dataset is the product of an international collaboration that includes NCBI, Ensembl, HUGO Gene Nomenclature Committee, Mouse Genome Informatics and University of California, Santa Cruz. Identically annotated coding regions, which are generated using an automated pipeline and pass multiple quality assurance checks, are assigned a stable and tracked identifier (CCDS ID). Additionally, coordinated manual review by expert curators from the CCDS collaboration helps in maintaining the integrity and high quality of the dataset. The CCDS data are available through an interactive web page (https://www.ncbi.nlm.nih.gov/CCDS/CcdsBrowse.cgi) and an FTP site (ftp://ftp.ncbi.nlm.nih.gov/pub/CCDS/). In this paper, we outline the ongoing work, growth and stability of the CCDS dataset and provide updates on new collaboration members and new features added to the CCDS user interface. We also present expert curation scenarios, with specific examples highlighting the importance of an accurate reference genome assembly and the crucial role played by input from the research community.

The Lick AGN Monitoring Project 2016 : dynamical modeling of velocity-resolved Hβ lags in luminous Seyfert galaxies
K.H. acknowledges support from STFC grant ST/R000824/1.We have modeled the velocity-resolved reverberation response of the Hβ broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitoring Project 2016 sample, drawing inferences on the geometry and structure of the low-ionization broad-line region (BLR) and the mass of the central supermassive black hole. Overall, we find that the Hβ BLR is generally a thick disk viewed at low to moderate inclination angles. We combine our sample with prior studies and investigate line-profile shape dependence, such as log10(FWHM/σ), on BLR structure and kinematics and search for any BLR luminosity-dependent trends. We find marginal evidence for an anticorrelation between the profile shape of the broad Hβ emission line and the Eddington ratio, when using the rms spectrum. However, we do not find any luminosity-dependent trends, and conclude that AGNs have diverse BLR structure and kinematics, consistent with the hypothesis of transient AGN/BLR conditions rather than systematic trends.Publisher PDFPeer reviewe
The Lick AGN Monitoring Project 2016: Dynamical Modeling of Velocity-Resolved H\b{eta} Lags in Luminous Seyfert Galaxies
We have modeled the velocity-resolved reverberation response of the H\b{eta}
broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic
Nucleus (AGN) Monitioring Project 2016 sample, drawing inferences on the
geometry and structure of the low-ionization broad-line region (BLR) and the
mass of the central supermassive black hole. Overall, we find that the H\b{eta}
BLR is generally a thick disk viewed at low to moderate inclination angles. We
combine our sample with prior studies and investigate line-profile shape
dependence, such as log10(FWHM/{\sigma}), on BLR structure and kinematics and
search for any BLR luminosity-dependent trends. We find marginal evidence for
an anticorrelation between the profile shape of the broad H\b{eta} emission
line and the Eddington ratio, when using the root-mean-square spectrum.
However, we do not find any luminosity-dependent trends, and conclude that AGNs

The Lick AGN Monitoring Project 2016 : velocity-resolved Hβ lags in luminous Seyfert galaxies
Funding: K.H. acknowledges support from STFC grant ST/R000824/1.We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast double spectrograph on the 3 m Shane telescope at Lick Observatory from April 2016 to May 2017. Targetingactive galactic nuclei (AGN) with luminosities of λLλ(5100 Å) ≈ 1044 erg s−1 and predicted Hβ lags of∼ 20–30 days or black hole masses of 107–108.5 M⊙, our campaign probes luminosity-dependent trends in broad-line region (BLR) structure and dynamics as well as to improve calibrations for single-epoch estimates of quasar black hole masses. Here we present the first results from the campaign, including Hβ emission-line light curves, integrated Hβ lag times (8–30 days) measured against V -band continuum light curves, velocity-resolved reverberation lags, line widths of the broad Hβ components, and virial black hole mass estimates (107.1–108.1 M⊙). Our results add significantly to the number of existing velocity-resolved lag measurements and reveal a diversity of BLR gas kinematics at moderately high AGN luminosities. AGN continuum luminosity appears not to be correlated with the type of kinematics that its BLR gas may exhibit. Follow-up direct modeling of this dataset will elucidate the detailed kinematics and provide robust dynamical black hole masses for several objects in this sample.Publisher PDFPeer reviewe
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
