Abstract/Description
This research examines tensions between Latino/a farmworkers, who rely on the seasonal harvest of saw palmetto (Serenoa repens [W. Bartram] Small) berries for increased livelihood security, and conservationists and land-managers who view harvesting as detrimental for wildlife. Informal harvesting occurs on public and private lands, sometimes without permission. Berries, though ubiquitous on the landscape, have become a contested resource. The rapid conversion of rural wildlife habitat into...
Show moreThis research examines tensions between Latino/a farmworkers, who rely on the seasonal harvest of saw palmetto (Serenoa repens [W. Bartram] Small) berries for increased livelihood security, and conservationists and land-managers who view harvesting as detrimental for wildlife. Informal harvesting occurs on public and private lands, sometimes without permission. Berries, though ubiquitous on the landscape, have become a contested resource. The rapid conversion of rural wildlife habitat into suburban development has increased State urgency to bring natural areas into protection along the Florida Ecological Greenways Network. Habitat infringement and associated pressures on wildlife by development has led to the promotion of the state-wide Florida Wildlife Corridor, based on the FEGN. This corridor would connect isolated Florida black bear (Ursus americanus floridanus) populations and Florida panthers (Puma concolor coryi) with other populations. The scale of the commercial berry industry is unknown, but is estimated at millions of pounds annually. State and wildlife conservationists are increasingly concerned with the perceived scale of the harvest and its possible associated effects on wildlife, particularly Florida black bears.

Hierarchical structure of cities in the European Union: A study of air transport accessibility

Hierarchical structure of cities in the European Union: A study of air transport accessibility.
Creator
Johns, David Matthew, Florida Atlantic University, Ivy, Russell L., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
The European Union (EU) has been evolving over the past years towards a goal of becoming an integrated economic space. Transportation, particularly, air transport, is a key step in the unification process, thus the development of the Single Air Market (SAM). The goals of this research are: (1) to identify the forces influencing air transport in the EU; (2) to identify the hierarchical structure of the major airports in the EU, and; (3) to compare the air transport hierarchy within the EU with...
Show moreThe European Union (EU) has been evolving over the past years towards a goal of becoming an integrated economic space. Transportation, particularly, air transport, is a key step in the unification process, thus the development of the Single Air Market (SAM). The goals of this research are: (1) to identify the forces influencing air transport in the EU; (2) to identify the hierarchical structure of the major airports in the EU, and; (3) to compare the air transport hierarchy within the EU with networks of other modes of transport. This research uses unique variables as surrogates to traditional transport accessibility studies. Results indicate that the spatial patterns of core regions are similar to other studies, with variations in the peripheral spatial pattern.

The geography of airfares: modeling market and spatial forces in the U.S. Airline Industry

The geography of airfares: modeling market and spatial forces in the U.S. Airline Industry.

Abstract/Description
The deregulation of the airline industry created a myriad of changes in the U.S. air transport system that has both defended and sparked debate on the wisdom of such policy change for over three decades. One of the promises of deregulation from its proponents in the 1970s was increased competition that would lead to a reduction in fares for consumers. Historic data and literature has indeed shown this to be to the case as average airfares have trended downward especially over the last twenty...
Show moreThe deregulation of the airline industry created a myriad of changes in the U.S. air transport system that has both defended and sparked debate on the wisdom of such policy change for over three decades. One of the promises of deregulation from its proponents in the 1970s was increased competition that would lead to a reduction in fares for consumers. Historic data and literature has indeed shown this to be to the case as average airfares have trended downward especially over the last twenty years. Nonetheless, the industry has become much more complex since deregulation in terms of pricing to the point that very sophisticated yield management computer models are used to achieve an optimum balance between load factors and price. Consequently, this has in turn translated into a haphazard experience for most air travelers in the United States; for instance, the cost of a ticket is sometimes lower traveling from coast to coast than within a particular region of the U.S. and paid fares for the exact same trip can deviate dramatically, often based on variation in the date of purchase. Additionally, this has also resulted in a spatial pattern where certain regions throughout the country have enjoyed lower airfares more so than others. This research seeks to identify this regional disparity using a geographically weighted regression and spatial autoregressive models in a sample of 6,200 routes between 80 primary U.S. airports. The results from the global model showed that variables which measure competition (airlines), operating cost (flights, distance) and elasticity (layover time) proved to be statistically significant and had a positive relationship with airfare The GWR results indicated that while some factors like distance, and hub size, were statistically significant almost nationwide, other factors such as frequency, presence of low cost carriers, and numbers of airlines were only statistically significant at certain airports. Finally, the spatial regressions models indicate that the spatial autocorrelation found in U.S. airfares resemble the first order properties of spatial autocorrelation (i.e. spatial heterogeneity) and not the second order properties (i.e. spatial dependence).
