The Family History of Sheryl M. Patterson-Coulibaly
No full textMany African Americans desire to research their family\u27s lineage. Many find that research difficult and as such, must rely on family stories passed down from generation to generation. This research began from family stories some of which was confirmed by research. This paper chronicles the Belford/Jackson family for six generations living in Northern Florida
BUILDING BIOCARBON AND RURAL DEVELOPMENT IN WEST AFRICA (BIODEV), M&E
No full textThe overarching goals of this assessment of BIODEV interventions are to: (1) understand differences across pilot and comparison sites in key selected outcomes that relate to improved governance and institutional fostering, germplasm systems and adoption of agroforestry innovations, marketing of agroforestry products; (2) determine the average short term effects on some selected outcomes (3) draw from our study findings policy-relevant recommendations on how BIODEV interventions might sustainably be supported or better refined to meet its goals more effectively
Similarity of catchment dynamics based on the interaction between streamflow and forcing time series: Use of a transfer entropy signature
No full textThe transfer of the hydrological information between catchments is founded on the definition of hydrological similarity, which is in turn strictly connected to the features to be regionalised. In order to characterise the catchment behaviour in the streamflow generation processes, the similarity should reflect also the interaction between meteorological forcings and river streamflow time series. While previous hydrological research has identified basins with similar meteorological forcings (i.e. similarity of climate) or with similar streamflow time-series (i.e. similarity of runoff response), the present work proposes, for the first time, to quantify the interaction between the entire time-series of different forcing data and streamflow observations, to be considered as a novel hydrological signature and used as a catchment similarity metric.
In particular, the present study proposes the use of a multi-variate entropy-based measure, the so-called transfer entropy, a time-asymmetric quantity which analyses the interaction between different signals. The concept of transfer entropy is applied for identifying the dominant hydrological processes occurring in a catchment, measuring the transfer of information from different meteorological forcings over the catchment to the corresponding observed time series of daily streamflow at the basin outlet. The resulting transfer entropy values are then used as signatures to characterise the main catchment dynamics, and a classification of the basins region is obtained assuming that similar values of transfer entropy correspond to hydrologically similar basins.
The methodology is tested on a densely-gauged set of more than 200 catchments across Austria and the outcomes of the approach are evaluated against a set of morpho-climatic catchment attributes and typical streamflow signatures.
Despite the limitations, the method is able to distinguish the predominant or partial role of snow melt and evapotranspiration across the dataset, helping to assess differences in catchment response time and to highlight the role of very high orographic precipitation in catchments with a dominant snow regime. The study demonstrates the potential of transfer entropy as complementary to consolidated streamflow signatures for assessing hydrological similarity and for quantifying the connection between different catchment processes
ENERGY SUPPLEMENTATION STRATEGIES FOR WHEAT PASTURE STOCKER CATTLE UNDER UNCERTAIN FORAGE AVAILABILITY
No full textEnergy supplementation provides a means of reducing production risk of growing stocker cattle on winter wheat pasture. This study addresses the issue of risk aversion and energy supplement input use. Differences in supplementation practices induced by risk aversion and the effects of cattle and feed market conditions are examined. Results show that supplementation practices are likely to be similar across producers, irrespective of their risk attitudes. Cattle and feed market conditions, however, markedly affect supplementation practices. These findings provide information for assisting stockmen in identifying efficient supplement strategies.Risk, Wheat pasture grazing, Numerical integration, Energy supplementation, Livestock Production/Industries,

Ultrastructural changes of cardiac valves in bacterial endocarditis
No full textAim. The principal objective of this study was to document morphological changes in valves with acute endocarditis in order to gain further knowledge of the pathogenesis of these diseases. Methods. Scanning and transmission electron microscopic investigations were carried out on explanted human heart valves to reveal ultrastructural changes due to bacterial endocarditis. Results. Bacterial inflammation endocarditis initially induced metaplasia of the endothelial cells which then lose contact with each other. in the 2(nd) phase of the disease, the collagen fibres are systematically removed whereby large cavities. appear. in the 3(rd) phase, localised hyperplasia of collagen fibres was observed often resulting in the development of vegetation. The ultrastructural changes are uniform and independent of the bacterial species. Conclusion. Bacterial endocarditis is therefore a set of complex interactions between endothelial cells and bacteria which should be taken into consideration for the development of new therapeutic approaches

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
