Effects of grass roots on the erodibility of topsoils during concentrated flow

In unequal societies, the rich may benefit from shaping economic institutions in their favor. This paper analyzes the dynamics of institutional subversion by focusing on public protection of property rights. If this institution functions imperfectly, agents have incentives to invest in private protection of property rights. The ability to maintain private protection systems makes the rich natural opponents of public protection of property rights and precludes grass-roots demand to drive the development of the market-friendly institution. The economy becomes stuck in a bad equilibrium with low growth rates, high inequality of income, and wide-spread rent-seeking. The Russian oligarchs of the 1990s, who controlled large stakes of newly privatized property, provide motivation for this paper.

Second Wave

This paper explores the transformation of oral histories into a play about the founding of San Francisco Women's Building based on extensive interviews. My impetus for writing She Rises Like a Building to the Sky was to portray the kind of grass roots feminist organization primarily composed of lesbians that made up a large part of the second wave of the Women's Movement in the 1970's and early 1980's. The evolution of She Rises is discussed from three positionalities I occupied over an extensive period of time: oral historian, playwright and eventual community member. Excerpts from She Rises are used to illustrate the lessons I learned in the process of creating this work. I will discuss my self-collaboration in terms of the oral historian's concern for fidelity, the playwright's desire to bring such material to life whether by fact or fiction, and the community member's fears of how others will view this rendition of their stories. The behind the scenes dramas reveal as much as the play itself about the challenges and rewards of undertaking such projects.

Abstract This paper focuses on the largely unexamined phenomenon of the developing trans-national suburban area west of Szczecin. Sadly the local communities in this functionally connected area struggle with national planning policies that are unsuitable for the region. The paper examines the impact of those processes on the border region in general and on the localities in particular. The paper investigates the consequences for local narratives and the cohesive development of the Euroregion and what position Polish and German communities took to develop the region, even without the necessary planning support. The region has succeeded in establishing grass-roots planning mechanisms which have helped to create a metropolitan-region working from the bottom up.

The Town

The Dzhida ore field in the Zakamensk district of Buryatia features high concentration of mineralization within a small area. The Dzhida deposit is composed of complex ore. The ore field contains commercial-value primary deposits: Pervomai stockwork of molybdenum, Kholtoson tungsten lode and Inkur stockwork of tungsten. The Modonkul river catchment basin lies inside the Dzhida ore field. A real threat to the town of Zakamensk is created by manmade sand-bulk (old) tailings and slurry dump. By now, the concentrated flow of natural and man-made sand enters the low terrace and floodplain of the Modonkul river in the form of a talus train. This study is focused on the influence of the mine drainage effluent and the Inkur tributary on the water chemistry in the Modonkul river. 80 water samples were taken from the surface layer 0-0.5 m thick at five stations. Physicochemical indices of water were measured at the water sampling points, and the water chemistry was analyzed in a laboratory. In the background conditions, cations and anions in the Modonkul water chemistry range in decreasing order as follows: Са2+ > Mg2+ > Na++К+ и HCO - > SO 2- > Cl-. In the zone of mixture of natural and mine process water, the chemistry changes: from hydrocarbonate to sulfate (anion), from calcium-magnesium to sodium-calcium (cation). Downstream the natural chemistry changes to the hydrocabonate-sulfate composition, with prevailing content of calcium in cations. Iron content of water lowers 3-4 times after influx of mine effluents, while the contents of Mn, Zn, Co and Cd grow and then decrease downstream.
