Charles Perry and Nathaniel Reed in Mesa Verde cave, Arizona. Charles Edward Perry (Chuck), 1937-1999, was the founding president of Florida International University in Miami, Florida. He grew up in Logan County, West Virginia and graduated from Bowling Green State University. He married Betty Laird in 1961. In 1969, at the age of 32, Perry was the youngest president of any university in the nation. The name of the university reflects Perry’s desire for a title that would not limit the scope of the institution and would support his vision of having close ties to Latin America. Perry and a founding corps opened FIU to 5,667 students in 1972 with only one large building housing six different schools. Perry left the office of President of FIU in 1976 when the student body had grown to 10,000 students and the university had six buildings, offered 134 different degrees and was fully accredited. Charles Perry died on August 30, 1999 at his home in Rockwall, Texas. He is buried on the FIU campus in front of the Graham Center entrance. Reed, Nathaniel P. (Nathaniel Pryor), 1933- serves on the Board of the National Geographic Society, the Everglades Foundation where he is Vice Chairman, and the Hope Rural School for migrant children. He received a B.A. from Trinity College in Connecticut. He was an officer in the U.S. Air Force and was Assistant Secretary of the Interior for the U.S. Fish and Wildlife Service as well as the U.S. Parks Service. He has also served on the boards of the National Audubon Society, the Nature Conservancy, the National Parks and Conservation Association, and the American Rivers. He is a board member emeriti of the Natural Resources Defense Council and 1000 Friends of Florida. He served on various environmental organization and committees under seven different governors in the state of Florida including as Chairman of the Commission on Florida’s Environmental Future. In 1972 he received the Cornelius Amory Pugsley National Medal Award.

In this study, I determined the identity, taxonomic placement, and distribution of digenetic trematodes parasitizing the snails Pomacea paludosa and Planorbella duryi at Pa-hay-okee, Everglades National Park. I also characterized temporal and geographic variation in the probability of parasite infection for these snails based on two years of sampling. Although studies indicate that digenean parasites may have important effects both on individual species and the structure of communities, there have been no studies of digenean parasitism on snails within the Everglades ecosystem. For example, the endangered Everglade Snail Kite, a specialist that feeds almost exclusively on Pomacea paludosa, and is known to be a definitive host of digenean parasites, may suffer direct and indirect effects from consumption of parasitized apple snails. Therefore, information on the diversity and abundance of parasites harbored in snail populations in the Everglades should be of considerable interest for management and conservation of wildlife. Juvenile digeneans (cercariae) representing 20 species were isolated from these two snails, representing a quadrupling of the number of species known. Species were characterized based on morphological, morphometric, and sequence data (18S rDNA, COI, and ITS). Species richness of shed cercariae from P. duryi was greater than P. paludosa, with 13 and 7 species respectively. These species represented 14 families. P. paludosa and P. duryi had no digenean species in common. Probability of digenean infection was higher for P. duryi than P. paludosa and adults showed a greater risk of infection than juveniles for both of these snails. Planorbella duryi showed variation in probability of infection between sampling sites and hydrological seasons. The number of unique combinations of multi-species infections was greatest among P. duryi individuals, while the overall percentage of multi-species infections was greatest in P. paludosa. Analyses of six frequently-observed multiple infections from P. duryi suggest the presence of negative interactions, positive interactions, and neutral associations between larval digeneans. These results should contribute to an understanding of the factors controlling the abundance and distribution of key species in the Everglades ecosystem and may in particular help in the management and recovery planning for the Everglade Snail Kite.

A global corporation values both profitability and social acceptance; its units mutually negotiate governance and represent a highly interdependent network where centers of excellence and high-potential employees are identified regardless of geographic locations. These companies try to build geocentric, or “world oriented” (Marquardt, 1999, p. 20), organizational cultures. Such culture “transcends cultural differences and establishes ‘beacons’ – values and attitudes – that are comprehensive and compelling” (Kets de Vries & Florent-Treacy, 2002, p. 299) for all employees, regardless of their national origins. Creating a geocentric organizational culture involves transforming each employee’s mindset, beliefs, and behaviors so that he/she can become “a world citizen in spite of having a national identity” (Marquardt, 1999, p. 47). The purpose of this phenomenological study was to explore how employees with different national identities experience a geocentric organizational culture of a global corporation. Phenomenological research aims to understand “how people experience some phenomenon—how they perceive it, describe it, feel about it, judge it, remember it, make sense of it, and talk about it with others” (Patton, 2002, p. 104). Twelve participants were selected using criteria, convenience, and snow-ball sampling strategies. A semi-structured interview guide was used to collect data. Data were analyzed inductively, using Moustakas’s (1994) Modification of the Stevick-Colaizzi-Keen Method of Analysis of Phenomenological Data. The participants in this study experienced a geocentric organizational culture of a global corporation as on in which they felt connected, valued, and growing personally and professionally. The participants felt connected to the companies via business goals and social responsibility. The participants felt valued by the company because their creativity was welcomed and they could contribute to the corporation certain unique knowledge of the culture and language of their native countries. The participants felt growing personally and professionally due to the professional development opportunities, cross-cultural awareness, and perspective consciousness. Based on the findings from this study, a model of a geocentric organizational culture of a global corporation: An employee perspective is proposed. Implications for research and practice conclude this study.

This research analyzed the spatial relationship between a mega-scale fracture network and the occurrence of vegetation in an arid region. High-resolution aerial photographs of Arches National Park, Utah were used for digital image processing. Four sets of large-scale joints were digitized from the rectified color photograph in order to characterize the geospatial properties of the fracture network with the aid of a Geographic Information System. An unsupervised landcover classification was carried out to identify the spatial distribution of vegetation on the fractured outcrop. Results of this study confirm that the WNW-ESE alignment of vegetation is dominantly controlled by the spatial distribution of the systematic joint set, which in turn parallels the regional fold axis. This research provides insight into the spatial heterogeneity inherent to fracture networks, as well as the effects of jointing on the distribution of surface vegetation in desert environments.
