The Caddo Indian Burial Ground (3MN386), Norman, Arkansas

Human burials were exposed accidentally during construction of a city sewer treatment plant in Norman, Arkansas, in October 1988. Archeological salvage excavations in the days following, directed by Ann Early of the Arkansas Archeological Survey’s Henderson Research Station, identified two burials, a small cluster of residential features, and artifacts dating from the Archaic through Caddo periods. After discussions between the various agencies and groups involved, a new location was found for the sewer treatment plant. The human bone and associated grave goods were returned to the Caddo Tribe for reburial, and the site was covered up for protection. The site, 3MN386, originally named the Norman Sewer Plant site and now called the Caddo Indian Burial Ground in Norman, is part of a city park. The Southern Montgomery County Development Council has plans to install a series of signs along a walking path at the park to interpret the site. Site 3MN386 is located on a low terrace next to the confluence of Huddleston Creek and the Caddo River. Based on the distribution of chipped stone debris, the site was at least 1.5 hectares (almost 4 acres) in area, but the full extent of the site was never determined by archeological investigations. The archeological salvage excavations in 1988 were limited to a small area of 25 x 30 m where the burials and other features were uncovered. While artifacts diagnostic of Archaic and Fourche Maline periods were found at the site, the main use of the site was in the Mississippian period. Two Caddoan occupations between about AD 1250-1500 are indicated based on the materials associated with these features: an earlier residential use of the site that left the remains of a large circular house with hearth and a burned ash floor deposit; and a later use of the site as a cemetery

Broader niches revealed by fossil data don’t reduce estimates of range loss and fragmentation of African montane trees

This is the author accepted manuscript. The final version is available from Wiley via the DOI in this record.The data supporting the results already exists and is freely available in the Global Biodiversity Information Facility (GBIF) and the African Pollen Database (APD).Aim: Many species’ climate tolerances are broader than those estimated from current native ranges. Indeed, some Afromontane trees’ niches are up to 50% larger after incorporating fossil data. This expansion could reduce estimates of species’ future range loss due to climate change but also implies strong non-climatic limitations on species’ current ranges. One such limitation is land use, which fossil data suggest influences Afromontane tree distribution, preventing these trees from occupying warmer conditions than they currently do. We aim to assess the degree to which the broader climatic tolerances revealed by fossil data buffers projected range loss from climate and land use for Afromontane trees. Location: Africa. Time period: Last 21,000 years. Major taxa studied: Afromontane trees. Methods: We used species distribution models informed by both current and fossil distributions to project future ranges under climate and land-use projections. Results: We found that projected range reductions are only slightly ameliorated by incorporating fossil distributions and these improvements diminish further under severe land use or climate change scenarios. Taxa that are less impacted by climate are more impacted by intense land use. Depending on the severity of climate and land use, the geographic extent of Afromontane tree species’ ranges will contract by 40-85% and the trees will completely be lost from large portions of Africa. We projected that the surviving species’ ranges will become increasingly fragmented. Main conclusions: Maintaining Afromontane ecosystems will require mitigation of both climate and land-use change and protecting areas to optimize connectivity. Our findings caution that species with climate tolerances broader than their current range might not necessarily fare better under strong changes in climate or land use

Television and environmental sustainability: Arguing a case for a code of standards in NZ

This article explores the portrayal of the environment and environmental sustainability by free-to-air network television in New Zealand. The results are based on a three-month survey of a) the portrayal of the use and treatment of the environment, and b) the reporting of environmental news. While television includes environmentally-oriented programmes (eg. some BBC Horizon documentaries), there are no regular programmes about the state of the environment, sustainable use of resources and energy, and there is no regular environmental slot in the news in New Zealand. Some programmes and advertisements are environmentally unfriendly and a few trivialise resource abuse. It is argued that the media has an ‘orchestrational’ influence on social norms and behaviours, and that to eliminate counter-messages requires the addition of a new ‘environmental standard’ to the Code of Broadcasting Practice. It is also argued that coverage of environmental news is quite narrow and, in the case of Television New Zealand, inconsistent with the stated aims of the Television Charter. New Zealand  television could and should make a valuable contribution to environmental sustainability

Evolution of pulmonary inflammation and nutritional status in infants and young children with cystic fibrosis

Introduction Improved nutrition is the major proven benefit of newborn screening programmes for cystic fibrosis (CF) and is associated with better clinical outcomes. It was hypothesised that early pulmonary inflammation and infection in infants with CF is associated with worse nutrition. Methods Weight, height and pulmonary inflammation and infection in bronchoalveolar lavage (BAL) were assessed shortly after diagnosis in infants with CF and again at 1, 2 and 3 years of age. Body mass index (BMI) was expressed as z-scores. Inflammatory cells and cytokines (interleukin 1b (IL-1b), IL-6, IL-8 and tumour necrosis factor a (TNFa)), free neutrophil elastase activity and myeloperoxidase were measured in BAL. Mixed effects modelling was used to assess longitudinal associations between pulmonary inflammation, pulmonary infection (Staphylococcus aureus and Pseudomonas aeruginosa) and BMI z-score after adjusting for potential confounding factors. Results Forty-two infants were studied (16 (38%) male; 39 (93%) pancreatic insufficient); 36 were diagnosed by newborn screening (at median age 4 weeks) and six by early clinical diagnosis (meconium ileus). Thirty-one (74%) received antistaphylococcal antibiotics. More than two-thirds were asymptomatic at each assessment. Mean BMI z-scores wer

Properties of HxTaS2

The preparation of Hx TaS2 (0 \u3c x \u3c 0.87) is described. The compounds are only marginally stable at room temperature, slowly evolving H2S and H2 (and possibly Hp in air). Magnetic susceptibility data show that a low temperature transformation in 2H ... TaS2 (at so•K) is suppressed with the addition of hydrogen, and· at the same time the superconducting transition temperature T c rises from 0.8 to ~4.2•K at x = 0.11. Heat capacity measurements near this concentration show the superconductivity to be a bulk effect. Finally, by correlation of this data with susceptibility and T c measurements in other intercalation compounds, we suggest that the rise of T c (at low electron transfer) is due to suppression of the low temperature transformation and not due to an excitonic mechanism of superconductivity

Estimating the Economic Value of Australian Stock Herding Dogs

This study aimed to estimate the value of the typical Australian herding dog in terms of predicted return on investment. This required an assessment of the costs associated with owning herding dogs and estimation of the work they typically perform. Data on a total of 4,027 dogs were acquired through The Farm Dog Survey which gathered information from 812 herding dog owners around Australia. The median cost involved in owning a herding dog was estimated to be a total of AU$7,763 over the period of its working life. The work performed by the dog throughout this time was estimated to have a median value of AU$40,000. So, herding dogs typically provided their owners with a 5.2-fold return on investment. When respondents were asked to nominate the maximal, one-off, veterinary expenditure they would consider to remedy an illness or injury for an especially valued dog, the median response was AU$1,001–2,000 which is not concordant with the dogs’ calculated median lifetime value. The current findings equip working dog owners with useful information to make financially appropriate expenditure decisions related to their working dogs. This is expected to increase farm profitability and improve welfare for farm dogs
