Horace Kephart, pioneer interpreter of the southern highlands
No full textThis article is a memorial to Horace Kephart (1862-1931), a noted naturalist, woodsman, journalist, and author. In 1904, he left his work as a librarian in St. Louis and permanently moved to western North Carolina. His popular book, “Camping and Woodcraft” was first published 1906; the 1916/1917 edition is considered a standard manual for campers after almost a century of use. Living and working in a cabin on Hazel Creek in Swain County, Kephart began to document life in the Great Smoky Mountains, producing “Our Southern Highlanders” in 1913. Throughout his life, Kephart wrote many articles supporting the Great Smoky Mountains National Park.HORACE Ml. .. I II -% I! n

Exploring movement patterns and changing distributions of baleen whales in the western North Atlantic using a decade of passive acoustic data. Global Change Biology, (2020): 1-30, doi:10.1111/gcb.15191.Six baleen whale species are found in the temperate western North Atlantic Ocean, with limited information existing on the distribution and movement patterns for most. There is mounting evidence of distributional shifts in many species, including marine mammals, likely because of climate‐driven changes in ocean temperature and circulation. Previous acoustic studies examined the occurrence of minke (Balaenoptera acutorostrata ) and North Atlantic right whales (NARW; Eubalaena glacialis ). This study assesses the acoustic presence of humpback (Megaptera novaeangliae ), sei (B. borealis ), fin (B. physalus ), and blue whales (B. musculus ) over a decade, based on daily detections of their vocalizations. Data collected from 2004 to 2014 on 281 bottom‐mounted recorders, totaling 35,033 days, were processed using automated detection software and screened for each species' presence. A published study on NARW acoustics revealed significant changes in occurrence patterns between the periods of 2004–2010 and 2011–2014; therefore, these same time periods were examined here. All four species were present from the Southeast United States to Greenland; humpback whales were also present in the Caribbean. All species occurred throughout all regions in the winter, suggesting that baleen whales are widely distributed during these months. Each of the species showed significant changes in acoustic occurrence after 2010. Similar to NARWs, sei whales had higher acoustic occurrence in mid‐Atlantic regions after 2010. Fin, blue, and sei whales were more frequently detected in the northern latitudes of the study area after 2010. Despite this general northward shift, all four species were detected less on the Scotian Shelf area after 2010, matching documented shifts in prey availability in this region. A decade of acoustic observations have shown important distributional changes over the range of baleen whales, mirroring known climatic shifts and identifying new habitats that will require further protection from anthropogenic threats like fixed fishing gear, shipping, and noise pollution.We thank Chris Pelkie, David Wiley, Michael Thompson, Chris Tessaglia‐Hymes, Eric Matzen, Chris Tremblay, Lance Garrison, Anurag Kumar, John Hildebrand, Lynne Hodge, Russell Charif, Kathleen Dudzinski, and Ann Warde for help with project planning, field work support, and data management.

High Molecular Weight Glucan of the Culinary Medicinal Mushroom Agaricus bisporus is an α-Glucan that Forms Complexes with Low Molecular Weight Galactan
No full textAn a-glucan was isolated from the culinary medicinal mushroom A. bisporus by hot water extraction, ethanol precipitation and DEAE-cellulose chromatography. The resulting material showed a single HMW peak excluded from a Sephadex G50 column that could completely be degraded by α-amylase treatment. After heating in 1% SDS a small additional peak of low MW eluted from the G50 column. The monosaccharide composition of the main peak was evaluated by HPLC, and was found to consist of a majority of glucose (97.6%), and a minor proportion of galactose (2.4%). Methylation analysis and degradation by a-amylase indicated the presence of an a-glucan with a main chain consisting of (1®4)-linked units, substituted at O-6 by α-D-glucopyranose single-units in the relation 1:8. Mono- (13C-, 1H-NMR) and bidimensional [1H (obs.),13C-HSQC] spectroscopy analysis confirmed the a-configuration of the Glcp residues by low frequency resonances of C-1 at d 100.6, 100.2, and 98.8 ppm and H-1 high field ones at d 5.06, 5.11, and 4.74 ppm. The DEPT-13C-NMR allowed assigning the non-substituted and O-substituted –CH2 signals at d 60.3/60.8 and 66.2 ppm, respectively. Other assignments were attributed to C-2, C-3, C-4, C-5 and C-6 of the non-reducing ends at d 71.8; 72.8; 70.0; 71.3 and 60.3/60.8 ppm, respectively. The minor proportion of galactose that was demonstrated was probably derived from a complex between the a-glucan and a low molecular weight galactan
The role of infrastructure investment location in China's western development
No full textDevelopment of the western region is vital to the balanced growth of China. The author studies the impacts of infrastructure investment that may most efficiently alleviate the burden of geographical remoteness of the West. Having constructed the ?adjusted distance? to approximate the transport cost, which takes into account the effects of real distance and infrastructure development, the author defines the ?peripheral degree? to measure the effective remoteness of a province to an economic center. Using panel data for 1979?99 from the Chinese provinces, she shows that geographic attractiveness plays a significant role in aSolow-type growth determination model. Given the invariability of pure geographic position, progress in transportation facilities is essential to reduce the geographic handicap and to encourage the catching-up of the western region. The author?s simulation results show that the central transportation hubs (Hubei, Henan, and Hunan) merit most infrastructure investments, for they favor the development of many provinces, if regional balanced growth is considered as the prime objective. In particular, improvement in the transportation facilities in central hubs will have greater effects on western development than that in the western region by itself. Improvements in the transportation facilities of the central hubs substantially improves the geographic attractiveness of the western region by reducing the transport cost from the West to the Coast and by promoting the emergence of new economic centers in such hubs, which tends to modify the national economic geographic structure.Decentralization,Health Monitoring&Evaluation,Economic Theory&Research,Environmental Economics&Policies,Public Health Promotion,Economic Theory&Research,Achieving Shared Growth,Trade and Regional Integration,Economic Conditions and Volatility,Health Monitoring&Evaluation
An essay on economic reforms and social change in China
No full textThe author applies a systems-oriented"holistic"approach to China's radical economic reforms during the past quarter of a century. He characterizes China's economic reforms in terms of a multidimensional classification of economic systems. When looking at the economic consequences of China's change of economic system, he deals with both the impressive growth performance and its economic costs. The author also studies the consequences of the economic reforms for the previous social arrangements in the country, which were tied to individual work units-agriculture communes, collective firms, and state-owned enterprises. He continues with the social development during the reform period, reflecting a complex mix of social advances, mainly in terms of poverty reduction, and regresses for large population groups in terms of income security and human services, such as education and, in particular, health care. Next, the author discusses China's future policy options in the social field, whereby he draws heavily on relevant experiences in industrial countries over the years. The future options are classified into three broad categories: policies influencing the level and distribution of factor income, income transfers including social insurance, and the provision of human services.Economic Theory&Research,Banks&Banking Reform,Investment and Investment Climate,Privatization,Economic Systems
A typology for vulnerability and agriculture in Sub-Saharan Africa:
No full text"This paper considers vulnerability reduction in Sub-Saharan Africa (SSA) from a more aggregated macro viewpoint. We focus on risk related to agriculture, since vulnerability and agriculture are intimately linked in SSA due to the location of the poor, their dependence on agriculture and the inherent risks of an agricultural livelihood. We argue that agricultural growth is one of the most effective means for improving permanent incomes and reducing vulnerability. However, agriculture is not homogeneous, and the inherent risks vary across countries and regions. Therefore, we also discuss appropriate investment strategies and policy instruments for different sets of risks." from Authors' AbstractAgriculture, Vulnerability, Typology,
