Returns To Public Investments In Agriculture With Imperfect Downstream Competition, Stephen F. Hamilton, David L. Sunding
Returns To Public Investments In Agriculture With Imperfect Downstream Competition, Stephen F. Hamilton, David L. Sunding
Economics
A multiple-market framework is developed to measure the size and distribution of research benefits. The model considers an upstream raw product market and a downstream finished product market and allows for imperfect competition in the intermediary food-processing sector. A central conceptual result is derived: an increase in raw product output is a sufficient condition for cost- reducing innovations in the farm sector to increase social welfare. A special case of linear farm supply and isoelastic processing production functions reveals that necessary conditions for welfare to decrease are a convergent farm supply shift, an oligopsonistic upstream market configuration, and increasing returns-to-scale …
Improving Water Properties To Increase Infiltration Characteristics, Richard W. O. Soppe, Stuart W. Styles
Improving Water Properties To Increase Infiltration Characteristics, Richard W. O. Soppe, Stuart W. Styles
BioResource and Agricultural Engineering
Water properties, such as the viscosity and surface tension, can be affected by temperature and surfactants to Increase infiltration rates into soils. Specifically, they will change the hydraulic conductivity of the soil. A simple soap solution and the new material PAM (inexpensive polymer chemical) were evaluated as surfactants. Laboratory experiments and field tests on a site in Davis, California were done to quantify the effects of changing the water properties. Additional effects, like the improved soil structure during infiltration and less soil particles in tailwater (reduced erosion due to runoff) were observed and are described in this paper. The conclusions …

Pollution And Economic Growth, Eric O'N. Fisher, Charles Van Marrewijk
Economics
We analyse a model of overlapping generations in which clean air, a pure public good, is used as a private input into production. Although production exhibits constant returns to scale. endogenous growth can occur. In a laissez-faire equilibrium, firms generate rents that are the value of the pollution they create. These rents crowd out investment and slow economic growth. Such an equilibrium may not support Pareto optimal allocations, but a Pigouvian tax does. Hence, a pollution tax can yield a double dividend because it reduces pollution and increases growth.
Off-Farm Work By Census-Farm Operators: An Overview Of Structure And Mobility Patterns, Michael Swidinsky, Wayne H. Howard, Alfons Weersink
Off-Farm Work By Census-Farm Operators: An Overview Of Structure And Mobility Patterns, Michael Swidinsky, Wayne H. Howard, Alfons Weersink
Agribusiness
The purpose of this paper is to provide descriptive statistics on off-farm labour supply and farm/off-farm labour reallocation for Canadian farmers using cross-sectional data and cross-sectional panel data, respectively, obtained from the Canadian Census of Agriculture. This report is part of a larger study on the off-farm labour supply and labour mobility of farm operators (Swidinsky, 1997). The data indicates that a growing proportion of operators worked off-farm between 1971 and 1991. As well, operators who work off-farm have allocated greater amounts of time to the off-farm labour market. The share of census-farm operators reporting 97-228 days of off-farm work …
Maternal Employment, Child Care, And Nutritional Status Of 12-18-Month-Old Children In Managua, Nicaragua, Jessica F. Lamontagne, Patrice L. Engle, Marian F. Zeitlin
Maternal Employment, Child Care, And Nutritional Status Of 12-18-Month-Old Children In Managua, Nicaragua, Jessica F. Lamontagne, Patrice L. Engle, Marian F. Zeitlin
Psychology and Child Development
Relationships among women's employment, child care strategies, and nutritional status of children 12–18 months of age were examined in 80 Nicaraguan households sampled by randomized block design in 10 low income urban communities. Multiple regression analyses showed that children of employed mothers (56%) fared better in weight/height than those whose mothers were not employed. with and without controlling for socioeconomic status and maternal education, paternal financial support, child care adequacy, and sex and age of the child. Children with inadequate alternate child care (care by a preteen or care at the work place) had lower height for age, even controlling …
Dual Adaptation And Adaptive Generalization Of The Human Vestibulo-Ocular Reflex, Robert B. Welch, Bruce Bridgeman, Jason A. Williams, Regina Semmler
Dual Adaptation And Adaptive Generalization Of The Human Vestibulo-Ocular Reflex, Robert B. Welch, Bruce Bridgeman, Jason A. Williams, Regina Semmler
Psychology and Child Development
In two experiments, we examined the possibility that the human vestibulo-ocular reflex (VOR) is subject to dual adaptation (the ability to adapt to a sensory rearrangement more rapidly and/or more completely after repeated experience with it) and adaptive generalization (the ability to adapt more readily to a novel sensory rearrangement as a result of prior dual adaptation training). In Experiment 1, the subjects actively turned the head during alternating exposure to a visual-vestibular rearrangement (target/head gain = 0.5) and the normal situation (target/head gain = 0.0). These conditions produced both adaptation and dual adaptation of the VOR but no evidence …

Anticipating The Future: The University Of Michigan's Media Union, Michael D. Miller
Robert E. Kennedy Library
The Media Union is a new facility that brings together information resources, information technology, and media production studios. It is unique in the blending of those resources into an integrated program serving the entire University of Michigan and supporting interdisciplinary collaboration. The Media Union anticipates the future not only by the proximity of its informational resources but by bringing together different types of information specialists to work collaboratively. The article provides a thorough description of the facility, its administrative structure, and examples of how pre-existing organizational units made the transition into the new environment.
