Use Of Semi-Structured Interviews To Explore Competing Demands In A Prostate Cancer Prevention Intervention Clinical Trial (Pcpict), Theresa Crocker, Karen Besterman-Dahan, David Himmelgreen, Heide Castañeda, Clement K. Gwede, Nagi Kumar

The Qualitative Report

In this paper we report on findings from the first known study using qualitative methods to explore factors influencing physicians’ participation in an ongoing federally-funded prostate cancer chemoprevention clinical trial. We sought to identify ways to improve collaboration between researchers and physicians and enhance the success of future projects and employed purposive sampling to recruit physician/investigators who were involved or invited to participate in the trial. Using the data from open-ended semi-structured interviews, we examined patterns in their languaging and created themes. We found that individual and structural factors served as barriers and facilitators to participation. Willingness and desire to …

Comment On “Chemically Mediated Behavior Of Recruiting Corals And Fishes: A Tipping Point That May Limit Reef Recovery”, Andrew H. Baird, Vivian R. Cumbo, Joana Figueiredo, Saki Harii, Tom Hata, Joshua S. Madin

Marine & Environmental Sciences Faculty Articles

Dixson et al. (2014) report that coral larvae navigate towards chemical cues associated with healthy reefs and avoid cues from degraded reefs. However, the swimming capabilities of coral larvae and well-established patterns of recruitment and reef hydrodynamics indicate that coral larvae will not be able to use these cues to recruit to healthy reefs. Perfuming degraded reefs, as suggested by Dixson et al (2014), will not enhance recovery rather it will distract from the difficult task of reducing fishing effort and improving water quality.

Marginal Coral Populations: The Densest Known Aggregation Of Pocillopora In The Galápagos Archipelago Is Of Asexual Origin, Iliana B. Baums, Meghann Devlin-Durante, Beatrice A. A. Laing, Joshua S. Feingold, Tyler B. Smith, Andrew Bruckner, Joao Monteiro

Marine & Environmental Sciences Faculty Articles

Coral populations at distributional margins frequently experience suboptimal and variable conditions. Recurrent El Niño-Southern Oscillation (ENSO) warming events have caused extensive mortality of reef-building corals in the Eastern Pacific, and particularly impacted branching pocilloporid corals in the Galápagos Islands. Pocillopora spp. were previously more common and formed incipient reefs at several locations in the archipelago but now occur as scattered colonies. Here, we report an unusually concentrated aggregation of colonies and evaluate their current genetic diversity. In particular we focus on a large population of 1614 live Pocillopora colonies found in a volcanic lagoon along the southern shore of Isabela …

Background: As genome-wide sequence analyses for complex human disease determinants are expanding, it is increasingly necessary to develop strategies to promote discovery and validation of potential disease-gene associations.

Findings: Here we present a dynamic web-based platform – GWATCH – that automates and facilitates four steps in genetic epidemiological discovery: 1) Rapid gene association search and discovery analysis of large genome-wide datasets; 2) Expanded visual display of gene associations for genome-wide variants (SNPs, indels, CNVs), including Manhattan plots, 2D and 3D snapshots of any gene region, and a dynamic genome browser illustrating gene association chromosomal regions; 3) Real-time validation/replication …

Two Distinct Microbial Communities Revealed In The Sponge Cinachyrella, Marie L. Cuvelier, Emily Blake, Rebecca Mulheron, Peter J. Mccarthy, Patricia Blackwelder, Rebecca Vega-Thurber, Jose V. Lopez

Marine & Environmental Sciences Faculty Articles

Marine sponges are vital components of benthic and coral reef ecosystems, providing shelter and nutrition for many organisms. In addition, sponges act as an essential carbon and nutrient link between the pelagic and benthic environment by filtering large quantities of seawater. Many sponge species harbor a diverse microbial community (including Archaea, Bacteria and Eukaryotes), which can constitute up to 50% of the sponge biomass. Sponges of the genus Cinachyrella are common in Caribbean and Floridian reefs and their archaeal and bacterial microbiomes were explored here using 16S rRNA gene tag pyrosequencing. Cinachyrella specimens and seawater samples were collected from the …

A Sensitive Question: Asking About Race In A Research Interview, Laura O'Hare

The Qualitative Report

Conversations are significant, but often overlooked cultural sites where attitudes, beliefs, and values about race are both reified and challenged. As such, these sites deserve increased scholarly attention (Allen, 2007). We employed Brown and Levinson’s Politeness Theory as a framework to examine the discursive strategies used by 11 interviewers in a research context as they asked 115 patient participants (taking part in a larger study of patients at a community-based family medicine residency clinic) to identify their race, as well as to identify the discursive strategies used by patient participants who answered this question. Our analysis revealed that in their …

Critical Approach To Reflexivity In Grounded Theory, Stephen J. Gentles, Susan M. Jack, David B. Nicholas, K. Ann Mckibbon

The Qualitative Report

A problem with the popular desire to legitimate one’s research through the inclusion of reflexivity is its increasingly uncritical adoption and practice, with most researchers failing to define their understandings, specific positions, and approaches. Considering the relative recentness with which reflexivity has been explicitly described in the context of grounded theory, guidance for incorporating it within this research approach is currently in the early stages. In this article, we illustrate a three-stage approach used in a grounded theory study of how parents of children with autism navigate intervention. Within this approach, different understandings of reflexivity are first explored and mapped, …

The Effects Of An Extended Power Plant Shutdown On The Florida Manatee (Trichechus Manatus Latirostris) In Port Everglades, Florida, Christopher Grissett

HCNSO Student Theses and Dissertations

Florida manatees (Trichechus manatus latirostris) seek out warmer waters during winter months when ambient water temperatures drop below 20 degrees Celsius. Over time, manatees have discovered artificial warm water sites from power plant discharges in addition to natural sites such as springs and passive thermal refugia (PTRs). The Florida Power and Light (FPL) Port Everglades power plant in Broward County is one such artificial warm water refuge used by manatees. This plant was shutdown on July 16, 2013, and is expected to remain off line for at least three years during demolition and construction of a new facility. …

Habitat And Seasonal Distribution Of The North American River Otter (Lontra Canadensis) And Vertebrate Species Assemblages In Two Protected Areas Of The Florida Everglades, Catherine Faye Hamilton

HCNSO Student Theses and Dissertations

The Florida Everglades ecosystem is threatened by human development, increased pollution, freshwater scarcity, and invasive species; factors that have negatively impacted the Everglades and native species health and populations. Man-made canals and levies have redirected the natural flow of fresh water from Lake Okeechobee into the Florida Everglades, starving central and south Florida ecosystems of necessary fresh water and nutrients. Through the efforts of the Comprehensive Everglades Restoration Project (CERP), freshwater is being redirected back into central and south Florida, returning the sheet flow of water back into the Everglades. Monitoring species abundance in the Everglades is a beneficial conservational …

The Political Economy Of Ivory As A “Conflict Resource”, Natasha White

Peace and Conflict Studies

The past year has seen attention directed, both in policy discourse and the media, towards the implication of Central African non-state armed groups in poaching and ivory trafficking. Engaging with both mainstream political economy analyses and work on the “geographies of resource wars,” this paper turns to the case of ivory as a “conflict resource,” through the case study of the Lord’s Resistance Army. It begins by outlining the contextual specificities and conditions of access, before assessing the compatibility of the resource’s biophysical, spatial and material characteristics with the needs of regional armed groups and the LRA in particular. Though …

Converting Capital: The Experiences Of Latinas/Os In Graduate Health Care Programs, Maristela C. Zell

The Qualitative Report

This qualitative study combines critical race theory, cultural capital theory, and counter-storytelling to examine the experiences of Latina/o in graduate health care programs. Community cultural wealth provided the framework to investigate the mechanisms by which students converted their sociocultural assets into the kinds of social, cultural, and educational capital needed to succeed in a graduate program and pursue their career goals. A qualitative content analysis was employed to interpret participants’ conversion experiences. The forms of community cultural wealth described by Yosso – aspirational, linguistic, familial, navigational, social, and resistant – intersected and interacted with one another. Aspirational and linguistic forms …

Acute Repeated Intracerebroventricular Injections Of Angiotensin Ii Reduce Agonist And Antagonist Radioligand Binding In The Paraventricular Nucleus Of The Hypothalamus And Median Preoptic Nucleus In The Rat Brain, Robert C. Speth, Peter J. Vento, Eduardo J. Carrera, Luz Gonzalez-Reily, Andrea Linares, Kira Santos, Jamala D. Swindle, Derek Daniels

HPD Articles

Angiotensin II (Ang II) stimulates water and saline intakes when injected into the brain of rats. This arises from activation of the AT1 Ang II receptor subtype. Acute repeated injections, however, decrease the water intake response to Ang II without affecting saline intake. Previous studies provide evidence that Ang II-induced water intake is mediated via the classical G protein coupling pathway, whereas the saline intake caused by Ang II is mediated by an ERK 1/2 MAP kinase signaling pathway. Accordingly, the different behavioral response to repeated injections of Ang II may reflect a selective effect on G protein coupling. To …

Mammalian Keratin Associated Proteins (Krtaps) Subgenomes: Disentangling Hair Diversity And Adaptation To Terrestrial And Aquatic Environments, Imran Khan, Emanuel Maldonado, Vitor Vasconcelos, Stephen J. O'Brien, Warren E. Johnson, Agostinho Antunes

Marine & Environmental Sciences Faculty Articles

Background: Adaptation of mammals to terrestrial life was facilitated by the unique vertebrate trait of body hair, which occurs in a range of morphological patterns. Keratin associated proteins (KRTAPs), the major structural hair shaft proteins, are largely responsible for hair variation.

Results: We exhaustively characterized the KRTAP gene family in 22 mammalian genomes, confirming the existence of 30 KRTAP subfamilies evolving at different rates with varying degrees of diversification and homogenization. Within the two major classes of KRTAPs, the high cysteine (HS) subfamily experienced strong concerted evolution, high rates of gene conversion/recombination and high GC content. In contrast, high glycine-tyrosine …

Possible Recovery Of Acropora Palmata (Scleractinia:Acroporidae) Within The Veracruz Reef System, Gulf Of Mexico: A Survey Of 24 Reefs To Assess The Benthic Communities, Elizabeth Anne Larson, David S. Gilliam, Mauricio Lopez Padierna, Brian K. Walker

Marine & Environmental Sciences Faculty Articles

Recent evidence shows that Acropora palmata within the Veracruz Reef System, located in the southwestern Gulf of Mexico, may be recovering after the die off from the flooding of the Jamapa River and a dramatic cold water event in the 1970s. Since this decline, few surveys have documented the status of A. palmata. The 28 named reefs in the system are divided into 13 northern and 15 southern groups by the River. Between 2007 and 2013, we surveyed 24 reefs to assess the benthic communities. Seven of the 11 reefs surveyed in the northern group and all in the …

Modeling Flightless Galapagos Seabirds As Impacted By El Nino And Climate Change, Brian Seth Putman

HCNSO Student Theses and Dissertations

Noteworthy species endemic to the Galapagos Islands off Ecuador are two flightless birds, the Galapagos Penguin (Spheniscus mendiculus) and Flightless Cormorant (Phalacrocrax harrisi). Both adapted increased swimming ability at the cost of flight. This however has limited their ability to find richer feeding grounds in times of low resource availability, or to escape potential predators. Their population numbers, though small, were stable. Stress on this stability has increased since human arrival. Various invasive species from pets, farm animals and rats to even mosquito vectors of avian disease accompanied humans. . El Nino Southern Oscillation or ENSO …
