A Domain Aware Genetic Algorithm For The P-Median Problem, Dennis Vickers

CCAC Theses and Dissertations

The p-median problem is an NP-complete combinatorial optimization problem often used in the fields of facility location and clustering. Given a graph with n nodes and an integer p < n, the p-median problem seeks a set of p medians such that the sum of the distances of the n nodes from their nearest median is minimized. This dissertation develops a genetic algorithm that generates solutions to the p-median problem that improves on previously published genetic algorithms by implementing operators that exploit domain specific information. More specifically, this GA explores the following:

(1) The advantages of using "good" solutions generated using extant heuristics in the initial generation of chromosomes.

(2) The effectiveness of a crossover operation that exchanges centers in the same neighborhood rather than exchanging arbitrarily chosen subsets of centers.

(3) The efficacy of using a biased mutation operator that favors replacing existing medians from less fit chromosomes with non-median nodes from the same neighborhood as the median being replaced.

Comparison Of Wetland Assessment Methods, Kerstin Green

HCNSO Student Theses and Dissertations

After many decades of being considered useless and often destroyed wetlands have become valued for the many functions they provide. To make informed wetland management decisions biologists have to develop practical, rapid, and inexpensive ways to assess biological conditions and functions. Ideally these assessment methods have to measure more than one attribute of the wetland to represent the overall condition of the biological community. For this project I conducted field assessments at mitigation sites in Pembroke Pines, Florida, to see how the newest method used in the State of Florida, the Uniform Mitigation Assessment Method (UMAM), compared to the older …

Wiki Behavior In The Workplace: Emotional Aspects Of Content Development, Deborah A. Gears

CCAC Theses and Dissertations

Wikis have been found to be an easy-to-use, low-cost, and Internet-based technology useful in creating and mobilizing knowledge. Wikis hosted within firms (corporate wikis) have become a popular way for employees to share information and collaborate.

Preliminary research suggested that as few as 6% of wiki consumers contributed to the development of wiki pages. Conventional approaches argued that employees judged the costs of participating in wikis (e.g., authoring or changing material, reading messages, following an argument, and posting responses) to exceed the benefits of participating in wikis (e.g., recognition, reputation etc.) - thus many people "lurked" but did not post. …

Risk Of Nursing Home Admittance Among Working Age Residents With Mental Illness, Stephanie Jones Bernard

The Qualitative Report

The number of working age (18-64) nursing home (NH) residents with a mental diagnosis at admission rose from 70,600 in 1997 to 97,200 in 1999 (Jones, 2002). Utilizing the Behavioral Model for Vulnerable Populations (Gelberg, Andersen, & Leak, 2000), I examined factors associated with NH admittance in a sample of working age residents with mental illness. I conducted a qualitative analysis of 20 residents' healthcare and social experiences leading to NH admittance. Data came from semi-structured interviews, medical records, and clinicians. Results showed that homelessness, drug abuse, and low functional status were perceived by residents to play a role in …

How-To Data Collection Series: The Evolution Of The Focused Discussion Group: From Non-Participant To One Of The Crew, José Luis Calderón

The Qualitative Report

This article is part of The Weekly Qualitative Report's occasional series on "How-To Collect Qualitative Data." The qualitative data collection method described is that of focused discussion groups (FDG's). This method involves the moderator, or scripter as is the preferred term in focused discussion groups, to move beyond that of a non-participant data collector to that of an engaged participant-observer, observer-participant who is willing to get into the discussion with the participants and to provide accurate information to them while prodding them to discuss the topic in increasingly personally meaningful ways. Focused discussion groups are particularly helpful for working with …

Seasonal Aggregations Of The Florida Manatee (Trichechus Manatus Latirostris) In The Port Everglades And Intracoastal Regions Of Fort Lauderdale, Florida., Jaime M. Goldman

HCNSO Student Theses and Dissertations

The Florida manatee (Trichechus manatus latirostris), a subspecies of the West Indian manatee, is one of the most endangered marine mammals in United States waters. The Florida manatee is the only manatee that ranges into subtropical and temperate regions. During the winter months manatees adopt a “refuging strategy” where they aggregate at warm-water sources immediately following decreases in the ambient water temperature to below 20° C (68° F) in order to avoid cold stress syndrome (CSS). During the winter manatees aggregate in warm water refuges, including natural warm water springs and the effluent discharges of power plants.

At₁ Angiotensin Ii Receptor And Novel Non-At₁, Non-At₂ Angiotensin Ii/Iii Binding Site In Brainstem Cardiovascular Regulatory Centers Of The Spontaneously Hypertensive Rat, Erick A. Bourassa, Xiefan Fang, Xia Li, Alan F. Sved, Robert C. Speth

HPD Articles

Spontaneously hypertensive rats (SHR) have an activated brain angiotensin system that contributes to the elevation of blood pressure in this animal model. Physiological and pharmacological studies suggest that hyperactivation of brain AT₁ angiotensin receptors is a major pathophysiological factor. Consistent with these observations, radioligand binding studies indicate widespread up-regulation of brain angiotensin receptors in SHR. One key brainstem site in which AT₁ receptor stimulation appears to contribute to the elevated blood pressure in SHR is the rostral ventrolateral medulla (RVLM). However, no quantitative comparison of AT₁ receptor binding in the RVLM has been made in SHR versus normotensive rats. A …

Background: The rising temperature of the world’s oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropical Atlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin.

Methodology/Principal Findings: Satellite-based tools provided warnings for coral reef managers and scientists, guiding both the timing and location of researchers’ field observations as anomalously warm conditions developed and spread across the greater Caribbean region from June to October 2005. Field surveys of bleaching and mortality exceeded prior …

Development And Evaluation Of Methods For Surveying Fish Populations In Nearshore Waters, Philip Smith, Ian Burrett, David Bailey, Francis Neat, David Donnan, Katherine Dunlop, James Thorburn, Rosanna Milligan, Steve Bastiman, Jane Dodd

Marine & Environmental Sciences Faculty Reports

1. Nearshore areas provide critical habitat for a range of fish species targeted by commercial and recreational fisheries, both of which make an important contribution to local economies in rural areas. However, established trawl survey methods are not suited to many nearshore areas, owing to shallow depths, obstructions on the sea bed or vulnerable habitats, so there is a lack of information on fish abundance in these areas.
2. The aim of the present project was to develop and test survey methods applicable to Scottish inshore waters, focussing on baited underwater cameras, fish traps, systematic rod-and-line surveys and observations of fish bycatch …

Genetic Introgression And The Survival Of Florida Panther Kittens, Jeffrey A. Hostetler, David P. Onorato, James D. Nichols, Warren E. Johnson, Melody E. Roelke, Stephen J. O'Brien, Deborah Jansen, Madan K. Oli

Biology Faculty Articles

Estimates of survival for the young of a species are critical for population models. These models can often be improved by determining the effects of management actions and population abundance on this demographic parameter. We used multiple sources of data collected during 1982–2008 and a live-recapture dead-recovery modeling framework to estimate and model survival of Florida panther (Puma concolor coryi) kittens (age 0–1 year). Overall, annual survival of Florida panther kittens was 0.323 ± 0.071 (SE), which was lower than estimates used in previous population models. In 1995, female pumas from Texas (P. c. stanleyana) were …

The Heroes' Journey: A Young Couple's Experience With Choriocarcinoma, Dan Marlowe, Jennifer Hodgson, Angela Lamson

The Qualitative Report

A 20 year retrospective qualitative case study was conducted to investigate the relational impact of choriocarcinoma (a type of gestational cancer) on a couple of child-bearing age. A unique feature to the study was that the primary investigator was the couple's biological son, initiating the first known auto-case study design. Using holistic content analysis, investigators learned that anticipatory grief played a central part in the couple's ultimate detachment and divorce. While the wife began to refocus her emotional energies on her children, in psychological preparation for her possible death, the husband focused on ways to keep the family finances together …

Daughters' Perspectives On Maternal Substance Abuse: Pledge To Be A Different Kind Of Mother, Anne P. Murphy, Joseph G. Ponterotto, Anthony A. Cancelli, Susan P. Chinitz

The Qualitative Report

The purpose of this grounded theory (Strauss & Corbin, 1998) study was to explore the experiences of racially and culturally diverse young mothers whose own mothers abused substances two decades ago when substance abuse peaked in inner city, urban neighborhoods in the United States and to identify the factors that have influenced how they parent their own children today. Semi-structured interviews were conducted with ten drug-free mothers who report having been raised by a mother who was addicted to drugs, primarily crack cocaine during their childhoods. The emergent grounded theory is that exposure to maternal substance abuse has a significant …

Fish Communities On The World's Warmest Reefs: What Can They Tell Us About The Effects Of Climate Change In The Future?, David A. Feary, John A. Burt, Andrew G. Bauman, Paolo Usseglio, Peter F. Sale, Georgenes Cavalcante

Marine & Environmental Sciences Faculty Articles

To examine the role of climatic extremes in structuring reef fish communities in the Arabian region, reef fish communities were visually surveyed at four sites within the southern Persian Gulf (also known as the Arabian Gulf and The Gulf), where sea-surface temperatures are extreme (range: 12–35° C annually), and these were compared with communities at four latitudinally similar sites in the biogeographically connected Gulf of Oman, where conditions are more moderate (range: 22–31° C annually). Although sites were relatively similar in the cover and composition of coral communities, substantial differences in the structure and composition of associated fish assemblages were …

Dynamic Oryza Genomes: Repetitive Dna Sequences As Genome Modeling Agents, Navdeep Gill, Phillip Sanmiguel, Braham Deep Singh Dhillon, Brian Abernathy, Hyeran Kim, Lincoln Stein, Doreen Ware, Rod Wing, Scott A. Jackson

Biology Faculty Articles

Repetitive sequences, primarily transposable elements form an indispensable part of eukaryotic genomes. However, little is known about how these sequences originate, evolve and function in context of a genome. In an attempt to address this question, we performed a comparative analysis of repetitive DNA sequences in the genus Oryza, representing ~15 million years of evolution. Both Class I and Class II transposable elements, through their expansion, loss and movement in the genome, were found to influence genome size variation in this genus. We identified 38 LTRretrotransposon families that are present in 1,500 or more copies throughout Oryza, and many are …
