Genealogy of today\u27s contributors to accounting research

This paper explores the intellectual roots of some of today\u27s major contributors to accounting research. Specifically, twenty-four present-day contributors were identified through their publication records and editorial service. For each of these contributors, the dissertation chairman was identified and assumed to be the primary mentor; in turn, dissertation chairmen for these individuals were also identified. Several iterations of this process produced four generations of accounting genealogy. The intellectual roots depicted in this paper highlight noteworthy linkages with members of the Accounting Hall of Fame, recipients of the Outstanding Educators Award, and with education in the discipline of economics

Uncertainties and speculations about the life cycle of the eastern oyster pathogen Haplosporidium nelsoni (MSX)

For 30 years, the pathogen Haplosporidium nelsoni (MSX) has been causing serious mortalities of eastern oysters Crassostrea virginica in the Delaware and Chesapeake bays of the eastern USA. Its life cycle is largely unknown, and methods for control are wanting. Breeding of resistant eastern oyster strains, at this time, offers the best hope for some degree of control of the disease. Although haplosporidians are known by their spores, controlled transmission, with one possible exception, has not been achieved in any of the 30 recognized species. Haplosporidium nelsoni rarely sporulates in eastern oysters, and this and other observations led to early speculation that another host probably exists. Based on apparent effects of environment on H. nelsoni abundance, particularly in Delaware Bay, we are attempting to profile a hypothetical alternate host. Recent increases in abundance and activity of MSX in Chesapeake and Delaware bays and in Virginia rivers are associated with droughts, but this is not true elsewhere. Distribution of H. nelsoni along the Atlantic coast appears to have spread slowly southward from Chesapeake and Delaware bays, but is not identified with eastern oyster mortalities in southern localities. To the north of the original epizootics, H. nelsoni has been scattered along the Long Island, Connecticut, and Massachusetts coasts for 30 years or more, usually without occurrence of serious mortalities of eastern oysters. Foci of increasing H. nelsoni activity with mortality, over the past 5 years, are of great concern in these areas. Careful examination of changes in these northern areas may contribute significantly to our understanding of the relationships between H. nelsoni and its environment.https://scholarworks.wm.edu/vimsbooks/1117/thumbnail.jp

On Calculation of Thermal Conductivity from Einstein Relation in Equilibrium MD

In equilibrium molecular dynamics, Einstein relation can be used to calculate the thermal conductivity. This method is equivalent to Green-Kubo relation and it does not require a derivation of an analytical form for the heat current. However, it is not commonly used as Green-Kubo relationship. Its wide use is hindered by the lack of a proper definition for integrated heat current (energy moment) under periodic boundary conditions. In this paper, we developed an appropriate definition for integrated heat current to calculate thermal conductivity of solids under periodic conditions. We applied this method to solid argon and silicon based systems; compared and contrasted with the Green-Kubo approach.Comment: We updated this manuscript from second version by changing the title and abstract.

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

Walk-through trap to control horn flies on cattle

"The horn fly, Haematobia irritans (Linnaeus), was introduced into the United States about a century ago. Since then, it has become one of the most important fly pests of pasture and range cattle. Although most cattle can tolerate up to 200 horn flies without showing economic losses, larger numbers of these flies decrease cattle weight gain and milk output."--First page.Robert D.

Combining Ability in Forage Sorghum Hybrids

Two cross-classified hybrid forage sorghum [Sorghum bicolor (L.) Moench] experiments were conducted at Mead, NE: Experiment 1 (3 females x 8 males), in 1973-75, and Experiment 2 (13 females x 2 males), in 1974-75. Data were collected on plant height, days to bloom, forage yield, percent dry matter (DM), percent protein, and in vitro dry matter disappearance (IVDMD) in both experiments and percent Brix in Experiment 1. Differences among hybrids averaged over females or over males were significant for each trait in one parental group or the other in each test except IVDMD in Test 1 and DM in Test 2. All traits were signficant for hybrid entries in both tests. Interactions of traits with years were often significant and, with the few degrees of freedom in F-tests, contributed to the nonsignificance of yield among females in Test 1 and males in Test 2. Genetic ratios indicated that general combining ability often was relatively high for days to bloom, height, DM, and forage yield; and was of some importance for IVDMD and Brix. Specific combining ability was most important for protein. Correlations among traits indicated that high forage yield often was positively correlated with tall height and late maturity; was negatively correlated with DM, protein, and IVDMD; and was not associated with Brix

The Pathology of the Feline Model of Mucopolysaccharidosis VI

Three cats with feline arylsulfatase-B-deficient mucopolysaccharidosis were studied by light and transmission electron microscopy. Membrane-bound cytoplasmic inclusions were present in hepatocytes, bone marrow granulocytes, vascular smooth muscle cells, and fibroblasts in skin, cornea, and cardiac valves. Central nervous system lesions were restricted to mild ventricular dilatation, perithelial cell vacuolation, and, in one animal, cord compression by vertebral exostoses. The lesions in these cats closely resembled those described in human patients with mucopolysaccharidosis VI (Maroteaux-Lamy syndrome)

Computational Materials Techniques for Thermal Protection Solutions: Materials and Process Design

Integrated computational materials techniques that span the atomistic and continuum scales have the potential to aid the design and manufacturing of thermal protection materials. Two cases demonstrating the practical application of these methods are discussed. Case one examines the selection of a high temperature coating for carbon/carbon, with the target application being a solar thermal propulsion heat exchanger. The performance of various refractory metal and metal-carbide coatings is characterized considering extreme thermal (3500 K) and chemical (hydrogen flows) conditions. The recession rate, hydrogen leakage, and likelihood of mechanical failure are characterized and provide directions for further experimental investigation. Case two examines the process optimization of a heat shield material composed of a woven silica fiber preform and cyanate ester resin. Frequently, internal voids were found to be present in this composite after the resin infusion and curing stages of manufacturing. Using the manufacturing conditions, computations indicate that both water adsorption and resin cure shrinkage are contributing factors to void formation. The results suggest an alternative process configuration for curing that would mitigate voids
