The Origin Of The Bemaraha Tsingy (Madagascar), Márton Veress, Dénes Lóczy, Zoltán Zentai, Gábor Tóth, Roland Schläffer Jan 2008

The Origin Of The Bemaraha Tsingy (Madagascar), Márton Veress, Dénes Lóczy, Zoltán Zentai, Gábor Tóth, Roland Schläffer

International Journal of Speleology

On Madagascar the most representative occurrences of tsingy are at Ankarana and Bemaraha. The tsingy are built up of giant grikes developed along cracks as well as karren features of much smaller size which cover the surfaces between grikes. We investigated the Bemaraha tsingy of Madagascar (surveyed profiles, measured grike directions, etc.) in order to reconstruct their development. The observations indicate that the majority of grikes of the tsingy are created from caves formed under the karst water table and subsequently opened up to the surface. The predominant processes may have been downward progressing dissolution or the collapse of cave …

The False Promise Of One Share, One Vote, Grant M. Hayden, Matthew T. Bodie Jan 2008

The False Promise Of One Share, One Vote, Grant M. Hayden, Matthew T. Bodie

All Faculty Scholarship

Shareholder democracy has blossomed. The once moribund shareholder franchise is now critical in takeover contests, merger decisions, and board oversight. However, the mechanisms of this vote remain largely under theorized. In this Article, we use voting rights and social choice theory to develop a new approach to the corporate franchise. Political democracies typically tie the right to vote to the level of a person's interest in the outcome of the election. Corporate democracies, on the other hand, tend to define the requisite institutional interest quite narrowly, and thus restrict the right to vote to shareholders alone. This restriction has found …

Evaluation Of An Oral Vaccination Program To Control Raccoon Rabies In A Suburbanized Landscape, Jason R. Boulanger, Laura L. Bigler, Paul D. Curtis, Donald H. Lein, Arthur J. Lembo Jr. Jan 2008

Evaluation Of An Oral Vaccination Program To Control Raccoon Rabies In A Suburbanized Landscape, Jason R. Boulanger, Laura L. Bigler, Paul D. Curtis, Donald H. Lein, Arthur J. Lembo Jr.

Human–Wildlife Interactions

We evaluated the efficacy of an oral rabies vaccination (ORV) program conducted in Erie County, New York, from July through September, 2002–2005. Ingress of the raccoon (Procyon lotor) rabies variant first occurred along the southern border of Erie County, New York, during 1992 and began to spread northward at a velocity of 31 km/year. Fixed-wing aircraft dropped ORV baits in rural landscapes; helicopters, hand baiting, and bait stations distributed baits in suburban landscapes (&#;x bait densities ranged 59–118 baits/km2). Our study objectives were to quantify rabies case densities, evaluate efficacy of intervention efforts, and determine biological, …

Landscape And Traffic Factors Influencing Deer–Vehicle Collisions In An Urban Enviroment, Janet W. Ng, Charlene Nielson, Colleen Cassady St. Clair Jan 2008

Landscape And Traffic Factors Influencing Deer–Vehicle Collisions In An Urban Enviroment, Janet W. Ng, Charlene Nielson, Colleen Cassady St. Clair

Human–Wildlife Interactions

Deer–vehicle collisions (DVCs) are steadily increasing across North America. The increase is particularly pronounced in urban green spaces where deer (Odocoileus spp.) populations and road densities are high. In the greater city of Edmonton, Alberta, Canada, 333 DVCs occurred from 2002 to 2004. To identify landscape and traffic correlates of these collisions, we built 3 statistical models. The first model assessed the importance of local variables and was based on a spatial precision of the nearest intersection to which collisions were referenced. The second model was based on landscape characteristics and used the nearest township intersection to aggregate collisions. …
