    Notes: This paper reports the detailed results of a comparison of the distribution and redistribution of income in seven countries using the Luxembourg Income Study (LIS) database. Use of LIS facilitates comparisons of inequality in respect to similarly-defined variables, permits methodological alternatives to be used, and allows the countries to be compared on aspects of income ranking and policy equity in ways not otherwise possible.The results indicate a pattern of inequality in which Sweden is the most equal, followed by Norway, the U.K. and Canada, while among the less equal countries Israel is generally more equal than Germany-or the USA., whose relative inequality depends on the measure chosen. Use of the LIS database also allows a more detailed explanation of these results, noting, for example, the role of cash benefits in increasing equality in Sweden and the U.K., and in aiding the bottom quintile in Germany; and the important part played by self-employment income in contributing to the high top quintile shares in Germany and Israel, and in rendering the Norwegian distribution less equal than that of its Scandinavian neighbour.The wealth of the database, however, means that methodological issues need to be treated both more explicitly and more carefully than is possible with more restrictive data. To interpret the data also requires a considerable degree of knowledge about the institutional features of tax and social provisions in each country, so that an income microdatabase could usefully be completed by one focused on the details of such provisions.

    Notes: The influence of tall fescue (Festuca arundinacea Schreb.) on germination and seedling growth of birdsfoot trefoil (Lotus corniculatus L.) was evaluated during 1983-85 at Manhattan, Kansas. Studies were designed to evaluate tall fescue cv. Kentucky-31 for possible allelopathic compounds, determine the effects of tall fescue on the germination, seedling growth and yield of birdsfoot trefoil, and to characterize the chemical properties of tall fescue. Fescue produced allelopathic compounds, particularly during the spring and autumn months when it was actively growing. The greatest trefoil inhibition occurred with fescue plant extracts prepared during the autumn (September and October). The concentration of fescue extracts influenced trefoil germination, with greater inhibition as fescue concentration increased. In a sand medium under greenhouse conditions, fescue extracts prepared in spring and autumn reduced trefoil growth by 50 and 56%, respectively, with no inhibition during the summer months. Under field conditions, full strength fescue extracts reduced trefoil plant populations by 14 and 57% with spring and autumn prepared extracts, respectively. Fescue competition reduced sod-seeded trefoil plants per unit area by 17 and 31% for spring and autumn seeding, respectively. Full strength fescue extracts reduced trefoil seedling growth by an average of 37%, and trefoil dry matter yields by 53%.

    Notes: Tax Increment Financing (TIF) is a popular yet controversial tool that allows local governments to use property tax revenue to fund the public costs of economic development. Since TIF gives one local government the power to affect the tax bases of the overlapping jurisdictions, there is uncertainty and argument on the part of government officials and taxpayers as to who really finances the program. To evaluate the alternative contentions, this paper presents a general methodology that identifies which taxpayers in which locations fund the TIF's expenditures, and sets forward the conditions under which such a local economic development policy can be beneficial to taxpayers. The paper applies the model to study the TIF program currently active in downtown Des Moines, Iowa. The evidence indicates that the taxpayers in the entire metropolitan area subsidized the downtown activities in the early years, but now pay lower property tax rates due to the city's TIF-financed urban revitalization program.

    Notes: : Lactose-negative Escherichia coil from cattle feces appeared as yellow, atypical colonies on m-FC medium plates with water samples from rangeland streams. The lactose-negative E. coil may impact stream water quality analyses if infrequent samples are collected; are less antibiotic resistant than the lactose-positive E. coili isolated from rangeland streams; and are colicinogenic toward all the laboratory strains of E. coil examined and toward 61 percent of the lactose-positive E. coil rangeland-stream isolates that were tested. This latter result could explain the potentially low degree of antibiotic resistance transfer from lactose-positive to lactose-negative E. coil. In addition, the colicinogenicity of the lactose-negative E. coil may interfere with microbiological water quality analyses that depend upon lactose fernientations with mixed populations of coliforms.

    Notes: Broccoli is well recognized as a source of glucosinolates and their isothiocyanate breakdown products. Glucoraphanin is one of the most abundant glucosinolates present in broccoli and its cognate isothiocyanate is sulphoraphane, a potent inducer of mammalian detoxication (phase 2) enzyme activity and anti-cancer agent. This study was designed to measure: glucosinolate levels in broccoli florets from an array of genotypes grown in several environments; the elevation of a key phase 2 enzyme, quinone reductase, in mammalian cells exposed to floret extracts; and total broccoli head content. There were significant environmental and genotype-by-environment effects on levels of glucoraphanin and quinone reductase induction potential of broccoli heads; however, the effect of genotype was greater than that of environmental factors. The relative rankings among genotypes for glucoraphanin and quinone reductase induction potential changed, when expressed on a per head basis, rather than on a concentration basis. Correlations of trait means in one environment vs. means from a second were stronger for glucoraphanin and quinone reductase induction potential on a per head basis than on a fresh weight concentration basis. Results of this study indicate that development of a broccoli phenotype with a dense head and a high concentration of glucoraphanin to deliver maximum chemoprotective potential (high enzyme induction potential/glucoraphanin content) is a feasible goal.

    Notes: : Conditions under which a given topological space does, or does not, possess a stronger maximal feebly compact topology are given. Procedures are developed which can be used, for certain feebly compact spaces, to obtain stronger maximal feebly compact spaces. Several examples are constructed.

    Notes: A finite-element method which incorporates mesh adaptation is used to calculate ground-water flow and pollutant transport. The formulation is based on the equations for conservation of mass, Darcy's law for an anisotropic medium, and the time-dependent species transport equation. Modifications have been implemented to the finite-element formulation to enhance computational speed and reduce storage; Petrov-Galerkin weighting of the advection terms provides numerical stability. An explicit time marching scheme is used to solve the transient equations. By utilizing unstructured adaptive meshing, species concentration and location of steep fronts are accurately resolved, even though one begins with a coarse mesh. The algorithm currently runs on PC and workstation class computers.

    Notes: The effects of soil fertility (two levels of soil nitrogen and two levels of soil phosphorus) and mycorrhizal infection on pollen production and pollen grain size were studied in two cultivars of the common zucchini (Cucurbita pepo). Overall, soil fertility and mycorrhizal infection had significant effects on traits affecting the male function of plants (staminate flower production, pollen production per flower and pollen grain size). There were also differences between the cultivars for these male traits in all three experiments. In addition, pollen grain size decreased toward the end of the growing season. In the mycorrhiza experiment, both phosphate concentration per pollen grain and total phosphate content per anther were greater but not significantly greater in the mycorrhizal plants than in the non-mycorrhizal plants. A significant negative relationship between pollen production and pollen grain size was found in the mycorrhiza and soil phosphorus experiments, indicating that there was a trade-off between pollen production and pollen size. This study is the first to show that mycorrhizal infection has an effect on male function (pollen production and size) in addition to the well-documented effects on female function (fruit/seed production and size).
