B700: Seasonal Home Residents in Five Maine Communities, Socio-Economic Characteristics, Use Patterns, and Environmental Attitudes
The trend of seasonal residency is growing in Maine. Maine, as a state and by individual communities, needs to know more about its seasonal residents if it is to accommodate their recreational demands now and plan for changing use patterns in the future. Such questions as how many children the seasonal resident has in his household, how many days the seasonal home is in use each season, and what the resident plans to do with his property in the future are all-important for recreational planning both state-wide and on an individual community basis.
In this study, the investigator has attempted to identify pertinent socio-economic characteristics of seasonal residents in Maine, to ascertain the use patterns and future plans of these residents, and to describe their attitudes toward certain aspects of their seasonal community\u27s environmental quality. The data are presented, for the most part, in descriptive tables. The text points out features of interest in each table, although the reader may discover information important to them beyond that highlighted by the writer. In addition, a profile of The Typical Seasonal Resident (pages 26-27) summarizes the most frequent responses for the group surveyed.https://digitalcommons.library.umaine.edu/aes_bulletin/1106/thumbnail.jp
ECONOMIC IMPLICATIONS OF GLOBAL CLIMATE CHANGE FOR WORLD AGRICULTURE
This paper challenges the hypothesis that negative yield effects in key temperate grain producing regions of the world resulting from global climate change would have a serious impact on world food production. Model results demonstrate that even with concurrent productivity losses in the major grain producing regions of the world, global warming will not seriously disrupt world agricultural markets. Country/regional crop yield changes induce interregional adjustments in production and consumption that serve to buffer the severity of climate change impacts on world agriculture and result in relatively modest impacts on world agricultural prices and domestic economies.Environmental Economics and Policy,
Parametric frequency mixing in the magneto-elastically driven FMR-oscillator
We demonstrate the nonlinear frequency conversion of ferromagnetic resonance
(FMR) frequency by optically excited elastic waves in a thin metallic film on
dielectric substrates. Time-resolved probing of the magnetization directly
witnesses magneto-elastically driven second harmonic generation, sum- and
difference frequency mixing from two distinct frequencies, as well as
parametric downconversion of each individual drive frequency. Starting from the
Landau-Lifshitz-Gilbert equations, we derive an analytical equation of an
elastically driven nonlinear parametric oscillator and show that frequency
mixing is dominated by the parametric modulation of FMR frequency
