- The purpose of this paper is to confront the notion of decline at the village level by illustrating a more immersive approach to sociological and demographic research within rural and remote communities. The research uses case studies of three villages in Australia, Canada, and Sweden, all of which have been labeled as declining villages, typified by population loss, an aging population, high rates of youth outmigration, and loss of businesses and services. This paper argues that focusing solely on quantitative indicators of demographic change provides a narrow view of rural village trajectories and ignores subtle processes of local adaptation that are hidden from quantitative data sets. Our research integrates quantitative data from the outside with qualitative data from the inside, including visual ethnography, to develop a more balanced perspective on how villages have been changing and what change could mean locally. These objectives are accomplished by revisiting a Dirt Research methodology applicable to a broad range of research into rural and remote villages.

- Six-coordinated heme groups are involved in a large variety of electron transfer reactions because of their ability to exist in both the ferrous (Fe2+) andferric (Fe3+) state without any large differences in structure. Our studies on hemes coordinated by two histidines (bis-His) and hemes coordinated by histidine and methionine (His-Met) will be reviewed. In both of these coordination environments, the heme core can exhibit ferric low spin (electron paramagnetic resonance EPR) signals with large g(max) values (also called Type I, highly anisotropic low spin, or highly axial low spin, HALS species) as Well as rhombic EPR (Type II) signals. In bis-His coordinated hemes rhombic and HALS envelopes are related to the orientation of the His groups with respect to each other such that (i) parallel His planes results in a rhombic signal and (ii) perpendicular His planes results in a HALS signal. Correlation between the structure of the heme and its ligands for heme with His-Met axial ligation and ligand-field parameters, as derived from a large series of cytochrome c variants, show, however, that for such a combination of axial ligands there is no clear-cut difference between the large g(max) and the "small ganisotropy" cases as a result of the relative Met-His arrangements. Nonetheless, a new linear correlation links the average shift of the heme methyl groups with the g(max) values. (c) 2009 Wiley Periodicals, Inc. Biopolymers 91: 1064-1082, 2009.
