The Haitian Informal Sector In Miami, Alex Stepick

Alex Stepick

The nature of immigration policy toward Haitians in southern Florida is largely responsible for the nature of their participation in the labor market. As individuals with an ambiguous status in the United States they are forced to work for low wages on the fringes of the formal sector of the economy or in Miami's growing informal sector. Most notably an example of generative economic activity is the growth of Little Haiti in Miami and the support it provides its residents.

Inventory Accounting And Profit Evaluation, Riccardo Fiorito

riccardo fiorito

In an inventory model with exogenous sales, FIFO and LIFO criteria are formalized and compared with national account estimates for intermediate and finished good products. The model is simulated using manufacturing input and output prices for Italy (1970-88). LIFO and NIPA estimates of inventory are usually close and also imply reliable measures of output levels and changes which can be shown by solving the quantity model. Conversely, FIFO exhibits larger profits and leads in real terms to unsatisfactory estimates of output changes.

Hepatic Microsomal N-Hydroxylation Of Aniline And 4-Chloroaniline By Rainbow Trout (Onchorhyncus Mykiss), Steven P. Bradbury, J. M. Dady, A. D. Hoffman, M. M. Voit, D. L. Olson

Steven P. Bradbury

N-Hydroxylation of aniline and 4-chloroaniline was quantified in rainbow trout microsomal preparations using h.p.l.c.-liquid scintillation methods. Radioactive phenylhydroxylamine and 4-chlorophenylhydroxylamine metabolites were identified by co-elution with non-labelled standards. The method provided resolution of metabolite standards, and quantification of both N-hydroxylated metabolites was achieved without derivatization. The maximum velocities at 25 degrees C were 33.8 +/- 1.40 and 22.0 +/- 0.98 pmol/min per mg for aniline and 4-chloroaniline N-hydroxylation, respectively. The Km values were 1.0 +/- 0.11 and 0.8 +/- 0.11 mM for aniline and 4-chloroaniline N-hydroxylation, respectively. These activities were not induced by treatment of the trout with Aroclor 1254 …

Comparison Of A Quantitative Microtiter Method, A Quantitative Automated Method, And The Plate-Count Method For Determining Microbial Complement Resistance, Margie D. Lee, Richard E. Wooley, John Brown, Kathy R. Spears, Lisa K. Nolan, Emmett B. Shotts Jr.

Lisa K. Nolan

A quantitative microtiter method for determining the degree of complement resistance or sensitivity of microorganisms is described. The microtiter method is compared with a quantitative automated system and the standard plate-count technique. Data were accumulated from 30 avian Escherichia coli isolates incubated at 35 C with either chicken plasma or heat-inactivated chicken plasma. Analysis of data generated by the automated system and plate-count techniques resulted in a classification of the microorganisms into three groups: those sensitive to the action of complement; those of intermediate sensitivity to the action of complement; and those resistant to the action of complement. Although the …

Comparison Of Chicken Plasma And Guinea Pig Serum In A Quantitative Microtiter Method Of Determining Microbial Complement Resistance, Richard E. Wooley, John Brown, Kathy R. Spears, Lisa K. Nolan

Lisa K. Nolan

Y. A quantitative microtiter method using chicken plasma is described for determining the degree of complement resistance or sensitivity of avian Escherichia coli isolates. Results obtained with the microtiter method using chicken plasma were compared with results obtained using commercially available standardized guinea pig serum as the source of complement. The test organisms consisted of five isolates of E. coli isolated from chickens. Three isolates were from flocks with colisepticemia; one was from a flock with omphalitis; and one isolate was a non-pathogenic control. Data were accumulated from the five avian E. coli isolates incubated at 35 C with either …

Reconstruction And Future Trends Of The Aids Epidemic In The United States, Ron Brookmeyer

Ron Brookmeyer

There has been considerable uncertainty in estimates of past and current human immunodeficiency virus (HIV) infection rates in the United States. Statistical estimates of historical infection rates can be obtained from acquired immunodeficiency syndrome (AIDS) incidence data and the incubation period. However, this approach is subject to a number of sources of uncertainty and two other approaches, epidemic models of HIV transmission and surveys of HIV prevalence, are used to corroborate and refine the statistical estimates. Analyses suggest the HIV infection rate in the United States grew rapidly in the early 1980s, peaked in the mid-1980s, and subsequently declined markedly. …

Should Asbestos In Buildings Be Regulated On An Environmental Or Occupational Basis?, Dean M. Hashimoto, Troyen A. Brennan, David C. Christiani

Dean M. Hashimoto

The issue of asbestos abatement in buildings may be viewed as part of a larger and more fundamental scientific and social issue: Should asbestos in buildings be regulated on an environmental or an occupational basis? The environmental approach to regulation of hazardous substances has a different emphasis from that of an occupational approach. The environmental approach emphasizes abatement of property damage, while the occupational approach is more concerned with decreased exposure levels and compensation for injuries to health. Similarly, the justifications for the two approaches also have a different emphasis. The need for environmental protection is justified on the basis …

The Role Of Federal Taxation In The Supply Of Municipal Bonds: Evidence From Municipal Governments, Gilbert E. Metcalf

Gilbert E. Metcalf

This paper considers ways in which federal tax policy affects municipal asset and debt holdings. The tax treatment of municipal bonds and income creates an arbitrage opportunity for communities to issue tax-exempt debt and invest in financial assets. The author presents evidence that suggests the rules in effect prior to 1986 to prevent this activity were not effective. He then develops and estimates a model of municipal bond supply. The author finds a semielasticity of 1.23 of long-term debt with respect to the spread between the after-tax rate of return and the municipal borrowing rate.

Naked Exclusion, Eric Bennett Rasmusen, J. Mark Ramseyer, John Wiley

Eric Bennett Rasmusen

Ordinarily, a monopoly cannot increase its profits by asking customers to sign agreements not to deal with potential competitors. If, however, there are 100 customers and the minimum efficient scale requires serving 15, the monopoly need only lock up 86 customers to forestall entry. If each customer believes that the others will sign, each also believes that no rival seller will enter. Hence, an individual customer loses nothing by signing the exclusionary agreement and will indeed sign. Thus, naked exclusion can be profitable.

The Influence Of Cation Size Upon The Infrared Spectrum Of Carbon Monoxide Adsorbed On Platinum Electrodes, Mark Anderson, Jimin Huang

Mark R. Anderson

The infrared spectrum of carbon monoxide adsorbed on polycrystalline platinum electrodes in the presence of acetonitrile solutions is examined. Acetonitrile solutions provide a wide double layer region (approximately 4 V) in which to investigate the observed potential dependence of the infrared peak position. The wider window allows for better comparisons of experimental data with theoretical predictions than those which are available from measurements conducted in aqueous solutions. It is found that (i) near-monolayer surface coverage can be obtained from solutions saturated with CO, (ii) the coverage stays constant over roughly the entire double layer region, (iii) the CO adsorbs to …

Measurements Of Deuteron Threshold Electrodisintegration: A Probe Of Short-Range Meson Exchange, K S. Lee, W Schmitt, H Baghaei, S Churchwell, R S. Hicks, R A. Miskimen, Gerald Alvin Peterson, K Wang

Gerald Alvin Peterson

The threshold electrodisintegration of the deuteron was measured with good energy resolution to a maximum four-momentum transfer squared of 42 fm-2. The data are compared with meson exchange calculations that show sensitivity to the choice of exchange-current form factor, the nucleon electromagnetic form factors, and the nucleon-nucleon potential. While conventional theories can give a reasonable description of the data, comparison of the data with quark cluster calculations shows poor agreement.

An Analytical Representation Of The Lowest Potential Energy Surface For The Reaction O(3 P)+Hcl (X  1Σ+)→Oh(X  2Π)+Cl(2 P), H. Koizumi, George C. Schatz, Mark S. Gordon

Mark S. Gordon

We present a new analytical representation of the lowest 3 A‘ energy surface for the reaction O(3 P)+HCl(X  1Σ+)→OH(X  2Π)+Cl(2 P). This surface is derived by fitting a b i n i t i o calculations, and adjustments are made to the barrier height so that rate constants derived from accurate quantum scattering calculations match the room temperature thermal rate constants. Contributions to thermal and state resolved rate constants arising from reaction on the lowest 3 A’surface are also considered. Comparisons of thermal and state resolved rate constants with experiment are good except at high temperature where the 3 A’ …

Trends In Industrial Development, John Mullin

John R. Mullin

Zenia Kotval and John Mullin review the key issues involving local land use decisions and industrial development in Massachusetts. They point out that the cumulative impact of town after town discouraging industrial development has resulted in creating a state where land use is a limiting factor for industrial development and growth. Concurring with recent thinking on economic development, the authors take a strong stance that our future economic well being must be based on a mixed economy where industry and manufacturing are a key player.

Swine Responses To Constant And Modified Diurnal Cyclic Temperatures, Hongwei Xin, James A. Deshazer

Hongwei Xin

Ad libitum fed and individually penned crossbred gilts (39 ± 2 kg) were exposed to a constant air temperature of 30.8*" C (CON) and equal-mean diurnal cyclic temperatures cycling from 26° to 33*^ C (RPK) and from 23.4° to 40° C (RNT). Fluorescent lighting with an intensity of 800 to 1100 L/m/m2 was provided from 0600 h to 2100 h. Measurements of feed intake, heat loss rates, water usage, growth, and ingestion behavior were made for a five-day period and replicated six times. Daily average heat loss rates, water usage, and feed conversion of the RPK and RNT pigs could …

Modeling Electroplating Rinse Systems Using Equation-Solving Software, Andrew C. Hillier, Clifford W. Walton

Andrew C. Hillier

Microcomputers are finding application in a vast array of academic and industrial settings, but are under-utilized in the electroplating industries. An often overlooked tool for computer simulation, for example, is equationsolving software. Such programs can predict the performance of a process system from basic mathematical relations without requiring the operator to have extensive knowledge of sophisticated programming and numerical solution techniques. A model of a multi-tank counter-current rinse system is described, then simulated with this software, and the results compared to actual plating facility rinse data, showing the excellent predictive qualities of this approach.
