Basement Membrane Polarizes Epithelial Cells And Its Loss Can Result In Neoplastic Disorganization, Donald Elliot Ingber May 1984

Basement Membrane Polarizes Epithelial Cells And Its Loss Can Result In Neoplastic Disorganization, Donald Elliot Ingber

Yale Medicine Thesis Digital Library

The studies described in this dissertation demonstrate that basement membrane may be required for maintenance of organized epithelial tissue architecture. The structural organization of normal rat pancreatic acinar epithelium is fully characterized in order to analyze its neoplastic disorganization within a pancreatic acinar cell tumor. Transmission electron microscopy and indirect immunofluorescence microscopy of frozen semithin tissue sections are utilized to localize different components of the plasmalemma, cytoskeleton, basement membrane and connective tissue. Normal acinar cells sit on a continuous basement membrane and display a polarized distribution of intracellular organelles, cytoskeletal elements, and distinct membrane domains while these organized cell relations …


Chemiosmotic Properties Of Isolated Secretory Granules From Parotid Glands Of Normal And Isoproterenol Treated Rats, Peter Raymond Arvan May 1984

Chemiosmotic Properties Of Isolated Secretory Granules From Parotid Glands Of Normal And Isoproterenol Treated Rats, Peter Raymond Arvan

Yale Medicine Thesis Digital Library

Secretory granule fractions were prepared isoosmotically from the parotid glands of normal rats and from rats that had received repeated injections of isoproterenol. These granules, purified extensively, are stable after isolation, making it possible to study biophysical parameters which may relate to their role in intracellular transport and secretion.Normal parotid granules have an internal pH of (TURN)6.8 and a low ionic permeability with respect to internal buffering capacity. By contrast, granules from the treated rats have an internal pH ranging from (TURN)7.7 in (0.3 M) sucrose media to (TURN)7.1 in (100 mM) KCl media; suggesting a large ionic permeability with …


A General Equilibrium Expression Of The Paradox Of Thrift, Christophe Chamley May 1984

A General Equilibrium Expression Of The Paradox Of Thrift, Christophe Chamley

Cowles Foundation Discussion Papers

A model is presented which is derived from some observations of Keynes on the nature of capital. The allocation of investment is analyzed in two economies with random demand shocks which are identical except for the types of markets. In the first, the combination of an asset and forward markets realizes the complete set of markets. In the second, the forward markets are replaced by spot markets. Consumers and entrepreneurs are rational and markets clear. A clear definition of the paradox of thrift is proposed and its existence is proven. The substitution of spot markets for forward markets generates fluctuations …


Optimal Spending And Money Holdings In The Presence Of Liquidity Constraints And Random Income Fluctuations, Richard H. Clarida May 1984

Optimal Spending And Money Holdings In The Presence Of Liquidity Constraints And Random Income Fluctuations, Richard H. Clarida

Cowles Foundation Discussion Papers

We examine the optimal spending behavior and money holdings of a risk averse individual who faces liquidity constraints and random fluctuations in his money income. Because of a cash-in-advance constraint, the individual has a well-defined transactions requirement for money balances. In addition, because money income is uncertain and money is — by assumption — the only available store of value, the risk averse individual also holds money balances as an inventory which can be drawn down in periods of unexpectedly low earnings. We establish the strict monotonicity properties of optimal expenditure and money demand decisions and show that the average …


Consumption, Liquidity Constraints And Asset Accumulation In The Presence Of Random Income Fluctuations, Richard H. Clarida May 1984

Consumption, Liquidity Constraints And Asset Accumulation In The Presence Of Random Income Fluctuations, Richard H. Clarida

Cowles Foundation Discussion Papers

Recent empirical research, Flavin (1981), Hagashi (1982), has rejected the certainty-equivalent formulation of permanent income hypothesis, Hall (1978). These findings are often attributed to households’ inability to borrow completely against expected future labor income. This paper is a theoretical investigation of optimal consumption behavior under risk aversion, random income fluctuations, and borrowing restrictions. Our principle objective is to establish the existence and to investigate the properties of the stationary probability distribution which characterizes the asymptotic behavior of consumption under these conditions.


A Comparison Of The Michigan And Fair Models: Further Results, Ray C. Fair, Lewis S. Alexander May 1984

A Comparison Of The Michigan And Fair Models: Further Results, Ray C. Fair, Lewis S. Alexander

Cowles Foundation Discussion Papers

This paper examines the equation-by-equation accuracy of the Michigan and Fair model using the method in Fair (1980). Emphasis is placed on examining the possible misspecification of the equations. In an earlier study, Fair and Alexander (1984), we used the method to examine the accuracy of the complete models. In the present study we are interested in the accuracy of the individual equations when considered in isolation from the rest of the model.

On The Stochastic Steady-State Behavior Of Optimal Asset Accumulation In The Presence Of Random Wage Fluctuations And Incomplete Markets, Richard H. Clarida Apr 1984

On The Stochastic Steady-State Behavior Of Optimal Asset Accumulation In The Presence Of Random Wage Fluctuations And Incomplete Markets, Richard H. Clarida

Cowles Foundation Discussion Papers

We establish rigorously the existence and properties of the stationary probability distribution which characterizes the accumulation of non-contingent financial claims by a risk averse individual who confronts random wage fluctuations and incomplete insurance markets. We show that there exists a unique, almost-everyhwere continuous stationary cumulative distribution function which characterizes the accumulation of non-contingent financial claims in a stochastic steady-state. This distribution is shown to possess a single mass point coinciding with the non-negative, finite borrowing limit faced by the individual. We establish that the stationary distribution which characterizes the asset accumulation of low time preference individuals is at least as …


Optimal Taxation Of Capital Income In Economies With Identical Private And Social Discount Rates, Christophe Chamley Apr 1984

Optimal Taxation Of Capital Income In Economies With Identical Private And Social Discount Rates, Christophe Chamley

Cowles Foundation Discussion Papers

The optimal capital income tax is analyzed in the framework of intertemporal efficient taxation. The relation between the zero tax in the long-run and the equality between private and social discount rates is emphasized. The properties of the dynamic second best path described for a specific example (convergence to a steady state and values of the capital income tax in the transition). The case where wealth is a specific utility argument is also considered.


Conditional Projection By Means Of Kalman Filtering, Richard H. Clarida, Diane Coyle Apr 1984

Conditional Projection By Means Of Kalman Filtering, Richard H. Clarida, Diane Coyle

Cowles Foundation Discussion Papers

We establish that the recursive, state-space methods of Kalman filtering and smoothing can be used to implement the Doan, Litterman, and Sims (1983) approach to econometric forecast and policy evaluation. Compared with the methods outlined in Doan, Litterman, and Sims, the Kalman algorithms are more easily programmed and modified to incorporate different linear constraints, avoid cumbersome matrix inversions, and provide estimates of the full variance-covariance matrix of the constrained projection errors which can be used directly, under standard normality assumptions, to test statistically the likelihood and internal consistency of the forecast under study.

Two Unusual Specimens Of Helaletes In The Yale Peabody Museum Collections, And Some Comments On The Ancestry Of The Tapiridae (Perissodactyla, Mammalia), Robert Milton Schoch Mar 1984

Two Unusual Specimens Of Helaletes In The Yale Peabody Museum Collections, And Some Comments On The Ancestry Of The Tapiridae (Perissodactyla, Mammalia), Robert Milton Schoch

Postilla

A calvarium, mandible and partial skeleton of Helaletes nanus and a partial upper dentition of Helaletes intermedius, both from the middle Eocene (Bridgerian) of Wyoming, are described and illustrated. Previously unrecognized cursorial specializations in the hindlimb of H. nanus suggest that it was not the direct ancestor of the Tapiridae, as hypothesized by some earlier workers. Alternatively, if H. nanus was the true ancestor of the Tapiridae, an initial tendency toward cursoriality in the hindlimb was later reversed. Only four described specimens are presently referred to H. intermedius. Due to morphological differences observed between these specimens, it is unclear if …


Revision Of Metacheiromys Wortman, 1903 And A Review Of The Palaeanodonta, Robert Milton Schoch Mar 1984

Revision Of Metacheiromys Wortman, 1903 And A Review Of The Palaeanodonta, Robert Milton Schoch

Postilla

Two species of the middle Eocene palaeanodont (Mammalia) genus Metacheiromys, M. marshi Wortman, 1903 (=M. tatusia Osborn, 1904) and M. dasypus Osborn, 1904 (=M. osborni Simpson, 1931), are recognized as valid. The previously described Palaeanodonta (Edentata) are reviewed and a new subfamily, Propalaeanodontinae, is erected for Propalaeanodon. Propalaeanodon is the plesiomorphous sister-group of the remaining metacheiromyids. The Epocoicotheriidae is a paraphyletic family including the monophyletic Epoicotheriinae and a number of poorly known genera that can not presently be assigned to distinct subfamilies.

The Behavior Of U.S. Short-Term Interest Rates Since October 1979, Richard H. Clarida, Benjamin M. Friedman Mar 1984

The Behavior Of U.S. Short-Term Interest Rates Since October 1979, Richard H. Clarida, Benjamin M. Friedman

Cowles Foundation Discussion Papers

Short-term interest rates in the United States have been “too high” since October 1979 in the sense that both unconditional and conditional forecasts, based on an estimated vector autoregression model summarizing the prior experience, underpredict short-term interest rates during this period. Although a non-structural model cannot directly answer the question of why this has been so, comparisons of alternative conditional forecasts point to the post-October 1979 relationship between the growth of real income and the growth of real money balances as closely connected to the level and pattern of short-term interest rates. This finding is consistent with the authors’ macroeconomic …


A Zero-One Result For The Least Squares Estimator, Donald W.K. Andrews Mar 1984

A Zero-One Result For The Least Squares Estimator, Donald W.K. Andrews

Cowles Foundation Discussion Papers

The least squares estimator for the linear regression model is shown to converge to the true parameter vector either with probability one or with probability zero under weak conditions on the dependent random variable and regressor variables. No additional conditions are placed on the errors. The dependent and regressor variables are assumed to be weakly dependent — in particular, to be strong mixing. The regressors may be fixed or random and must exhibit a certain degree of independent variability. No further assumptions are needed. The model considered allows the number of regressors to increase without bound as the sample size …


Current Account, Exchange Rate, And Monetary Dynamics In A Stochastic Equilibrium Model, Richard H. Clarida Mar 1984

Current Account, Exchange Rate, And Monetary Dynamics In A Stochastic Equilibrium Model, Richard H. Clarida

Cowles Foundation Discussion Papers

We construct a simple stochastic open-economy macro-economic model from the decision rules of rational optimizing agents, solving explicitly for the relationship between the model’s deep parameters, and the variance-covariance matrix of equilibrium returns on domestic and foreign assets. We use the model to study the dynamic relationship between exchange rate changes and current account flows in response to domestic monetary shocks, to establish the conditions under which exchange rate depreciations accompany current account deficits, and to investigate the link between time preference, risk aversion, and the dynamic exchange rate and current account response to monetary disturbances. The model generates current …

Robust Estimation Of Location In A Gaussian Parametric Model: Ii, Donald W.K. Andrews Mar 1984

Robust Estimation Of Location In A Gaussian Parametric Model: Ii, Donald W.K. Andrews

Cowles Foundation Discussion Papers

This paper extends the results of Andrews (1984) which considers the problem of robust estimation of location in a model with stationary strong mixing Gaussian parametric distributions. Three neighbourhood systems are considered, each of which contains the Hellinger neighbourhoods used in Andrews (1984). Optimal robust estimators for this dependent random variable model are found to be bounded influence estimators with optimal psi functions which are very nearly of Huber shape. These estimators are quite robust against different “amounts” of dependence, and against lack of dependence. To generate the optimal estimators a minimax asymptotic risk criterion is used, where minimaxing is …
