Growth fundamentalism in dying rural towns:Implications for rural development practitioners

In our paper we will try to connect the dynamics of community decline to individual responses. We will operate on two levels of reality. At the first level we will discuss the circumstances surrounding the recent decline of small communities in North Dakota. At the second level we will discuss how this decline affects small town residents' attitudes toward economic development. In the first level analysis we examine the thesis that the natural environment of community growth is economic exploitation; therefore, the decline of resource-based communities is natural and inevitable. We discuss the circumstances surrounding the recent decline of small communities in North Dakota. At the second level analysis, we operate at the level at which life circumstances and environments are shaped by political-economic institutions that in turn shape the behavior and mentality of communities, families, and individuals. We hypothesize that residents of declining small towns deny their powerlessness and adapt to their situation through intense dedication to economic growth. We develop a series of hypotheses to test this thesis using data from the North Dakota Rural Life Poll. In our conclusion, we discuss implications for rural development practitioners working in declining small towns where this intense dedication to economic development in prevalent.Dr. Stofferahn is an assistant professor in the Department of Sociology and director of the Social Science Research Institute at the University of North Dakota.

Calibration of the great american interchange

From radioisotopic (potassium-argon) age determinations of tuffs and magnetostratigraphy of Late Tertiary mammal-bearing beds in Catamarca Province, northwest Argentina, refined estimates have been obtained for the durations and boundaries of beds of Chasicoan (Middle Miocene) through Chapadmalalan (Pliocene) age. An age of 9.0 million years is tentatively accepted for the Chasicoan-Huayquerian boundary, 5.0 million years for the Huayquerian-Montehermosan boundary, and 3.0 million years for the Montehermosan-Chapadmalalan boundary. Procyonids (raccoons and their allies), a group of North American origin, are first recorded in South America in a level immediately below a unit dated at 6.0 million years. Cricetine rodents of the tribe Sigmodontini are first recorded in South America in beds of Montehermosan age in Argentina. Ground sloths, a group of South American origin, first appear in North America in Early Hemphillian time in beds dated between 9.5 and 9.0 million years. The Panamanian land bridge was established by 3.0 million years ago, and an interchange of the terrestrial faunas was well under way by Late Blancan time (around 2.5 million years before present) in North America and by Chapadmalalan time in South America.     

Luminescent colloidal silicon suspensions from porous silicon

A procedure for generating colloidal suspensions of Si that exhibit luminescence, attributed to quantum confinement effects, is described. Samples of n- or p-type Si that have been electrochemically etched to form porous Si can be ultrasonically dispersed into methylene chloride, acetonitrile, methanol, toluene, or water solvents, forming a suspension of fine Si particles that luminesce. Transmission electron microscopy analyses show that the Si particles have irregular shapes, with diameters ranging from many micrometers to nanometers. Luminescent, composite polystyrene/Si films can be made by the addition of polystyrene to a toluene suspension of the Si nanoparticles and casting of the resulting solution onto a glass slide.     

Germ cell chimerism: absence in parabiotic frogs

Embryos of the leopard frog deprived of primordial germ cells by treatment with ultraviolet light were joined in parabiosis with normal, unirradiated embryos. The irradiated member of the pair was not colonized by germ cells from its normal partner. Unlike the primordial germ cells of birds and mammals, the germ cells of frog embryos are not carried by the circulating blood.     

Germination of Melampyrum lineare: Interrelated Effects of Afterripening and Gibberellic Acid

Seed germination of Melampyrum lineare proceeds only after activation followed by an extended period of chilling. Up to one-third of seeds can be activated by storage at room temperature, while all seeds are activated if treated with gibberellic acid. Chilling before activation is ineffective.
