Neural Organization Of The Median Ocellus Of The Dragonfly: I. Intracellular Electrical Activity, Richard L. Chappell, John E. Dowling Aug 1972

Neural Organization Of The Median Ocellus Of The Dragonfly: I. Intracellular Electrical Activity, Richard L. Chappell, John E. Dowling

Publications and Research

Intracellular responses from receptors and postsynaptic units have been recorded in the median ocellus of the dragonfly. The receptors respond to light with a graded, depolarizing potential and a single, tetrodotoxin-sensitive impulse at "on." The postsynaptic units (ocellar nerve dendrites) hyperpolarize during illumination and show a transient, depolarizing response at "off." The light-evoked slow potential responses of the postsynaptic units are not altered by the application of tetrodotoxin to the ocellus. It appears, therefore, that the graded receptor potential, which survives the application of tetrodotoxin, is responsible for mediating synaptic transmission in the ocellus. Comparison of pre- and postsynaptic slow …

A Critical View Of Women's Studies, Catharine Stimpson Jan 1972

A Critical View Of Women's Studies, Catharine Stimpson

Women's Studies Quarterly

Below is a condensed version of Part I of an essay, to be called "What Matter Mind," that will appear next year in Women's Studies: An Interdisciplinary Journal. Part II of the essay describes the external opposition to Women's Studies, and Part III, a strategy for survival that aims to minimize internal dissent while reducing external opposition.

National Conference On Sex Role Stereotypes, Carol Ahlum Jan 1972

National Conference On Sex Role Stereotypes, Carol Ahlum

Women's Studies Quarterly

On November 24—26, the National Education Association held the first national conference on sex role stereotypes in elementary and secondary schools, under a grant from the Office of Education. Held at Airlie House, in Warrenton, Virginia, the conference drew about 200 participants, including representatives of such groups as the NAACP, the Feminists on Children's Media, NOW, Women on Words and Images, The Women's Action Alliance, The Feminist Press, as well as representatives from NEA affiliates from various sections of the country.


D-Structures And Their Semantics, Rohit J. Parikh Jan 1972

D-Structures And Their Semantics, Rohit J. Parikh

Publications and Research

"Many logicians are familiar with the game theoretic approach to semantics, due to Jaakko Hintikka. This paper by me contains class notes of a logic course at Boston University in fall 1972. It has similar game theoretic ideas, developed quite independently, but influenced by the work of A. Ehrenfeucht. It applies to a larger class of logics, including classical logic, intuitionistic logic and the *-semantics of Ehrenfeucht. The treatment is via D-structures which are finite approximations of infinite structures. For various reasons I did not publish this paper then, but some abstracts, both by myself as well as joint abstracts …


A Simple Method For The Construction Of Empirical Confidence Limits For Economic Forecasts, William (Bill) H. Williams, M. L. Goodman Dec 1971

A Simple Method For The Construction Of Empirical Confidence Limits For Economic Forecasts, William (Bill) H. Williams, M. L. Goodman

Publications and Research

A simple method for the construction of empirical confidence intervals for time series forecasts is described. The procedure is to go through the series making a forecast from each point in time. The comparison of these forecasts with the known actual observations will yield an empirical distribution of forecasting errors. This distribution can then be used to set confidence intervals for subsequent forecasts. The technique appears to be particularly useful when the mechanism generating the series cannot be fully identified from the available data or when limits based on more standard considerations are difficult to obtain.

Analysis And Prediction Of Telephone Demand In Local Geographic Areas, Douglas M. Dunn, William (Bill) H. Williams, W. Allen Spivey Oct 1971

Analysis And Prediction Of Telephone Demand In Local Geographic Areas, Douglas M. Dunn, William (Bill) H. Williams, W. Allen Spivey

Publications and Research

An approach to forecasting the demand or local area telephone service is presented in this paper. The specific problem discussed is the fore­ casting of main stations in three Michigan metropolitan areas. Several different statistical models are used. The first class of models introduced uses adaptive exponential smoothing and is based solely on the past history of the time series involved. Although appropriate data at the local area level are very difficult to obtain, two exogenous time series related to household formations are used to construct more elaborate models for one of the areas. The various models are evaluated by …

Effect Of Calcium, Temperature, And Polarizing Currents Upon Alternating Current Excitation Of Space-Clamped Squid Axons, Rita Guttman, Lon Hachmeister Sep 1971

Effect Of Calcium, Temperature, And Polarizing Currents Upon Alternating Current Excitation Of Space-Clamped Squid Axons, Rita Guttman, Lon Hachmeister

Publications and Research

Alternating current threshold excitation of space-clamped squid giant axons was measured as a function of frequency, external calcium concentration, temperature (from 10° to 35°C), and hyper- and depolarizing steps. In normal axons there is usually an optimum frequency at about 120 Hz, at which the threshold is a minimum. The threshold rises at both lower and higher frequencies to give a resonance curve. Low calcium causes an increase in optimum frequency, a decrease in current threshold, and an increase in sharpness of tuning in both real axons and axons computed according to the Hodgkin-Huxley formulation; high calcium causes opposite effects. …


A Statistical Grouping Of Corporations By Their Financial Characteristics., William (Bill) H. Williams, Michael L. Goodman Sep 1971

A Statistical Grouping Of Corporations By Their Financial Characteristics., William (Bill) H. Williams, Michael L. Goodman

Publications and Research

It appears to a widely held view that corporations with similar operational characteristics ought to have similar financial characteristics. For example, one might expect that the financial characteristics of two drug companies would be similar. This seems entirely reasonable. Unfortunately however, there does not appear to be any quantitative analysis of this point in the literature. Furthermore, discussions with our financial colleagues lead to the conclusion that, if such financial differentiation of corporations were possible, it is by no means obvious what the variables of differentiation would be. Consequently, such an analysis was undertaken and is described in this paper. …
