The question driving this research was, “In what ways do study circles empower artists to become community leaders around water issues?” Secondary questions focused on emerging environmental, water, and social justice themes as well as examples of increased water awareness and behavior change occurring as a result of individual participation in the study circles. Artists have a unique way of commanding attention and communicating about environmental concerns while functioning as catalysts for activism on a variety of …

Making The Value Of Development Visible: A Sequential Mixed Methodology Study Of The Integral Impact Of Post-Classroom Leader And Leadership Development, Laura Curnutt Santana

Antioch University Dissertations & Theses

In a time of increasing complexity, many organizations invest in leadership development programs to prepare those who will assume the role of leader. Although many studies have evaluated programs’ impact, the questions remain: does development happen in leadership development program? If so, what kind of development? And what is the participant’s experience of personal or organizational impact? The purpose of this sequential mixed methodology study is to address these three questions utilizing an online follow-through platform as a lens on 248 participants in the Center for Creative Leadership’s Leadership Development Program (LDP) who reported completing their LDP goals. Those who …

How Hospital Environmental Managers Learn Compliance: A Learning Process Model, Victoria Anne Jas

Antioch University Dissertations & Theses

Recent national media coverage of hospital mismanagement of hazardous materialsand waste has brought the practices of all hospitals into public scrutiny. Many people are amazed to learn that there is no national training or accreditation program for environmental management in hospitals. Hospitals are held to the same standards for hazardous materials management as are corporations in the industrial sector. Rural hospitals are particularly challenged because they have few resources. Overall, small hospitals need much improvement, but there are also examples of where individuals have done exemplary innovative work in improving environmental management. In this study I investigated the challenge rural …

What Does "Green" Mean?: Anthropogenic Climate Change, Geoengineering, And International Environmental Law, William D. Davis

Georgia Law Review

Dangerous anthropogenic interference with the climate is no longer merely impending-it is now inevitable. Surging fossil fuel use, combined with the failure of mitigation policies and the risk of positive feedback loops in the climate system, is generating interest in international,planetary- scale environmental engineering,known as geoengineering. Over the next few decades, nation-states are likely to engage in such activities as fertilizing marine biota with iron, injecting sulfur into the stratosphere,or deploying mirrors in outer space to counteract the effects of climate change. Such activities,however, risk environmental side effects and political instability, and could precipitate a backlash against geoengineering, which is …

Anthropogenic pressures on the Earth System have reached a scale where abrupt global environmental change can no longer be excluded. We propose a new approach to global sustainability in which we define planetary boundaries within which we expect that humanity can operate safely. Transgressing one or more planetary boundaries may be deleterious or even catastrophic due to the risk of crossing thresholds that will trigger non-linear, abrupt environmental change within continental- to planetary-scale systems. We have identified nine planetary boundaries and, drawing upon current scientific understanding, we propose quantifications for seven of them. These seven are climate change (CO2 concentration …

Non-Linearity In Ecosystem Services: Temporal And Spatial Variability In Coastal Protection, Evamaria W. Koch, Edward Barbier, Brian R. Silliman, Denise J. Reed, Gerardo M. E. Perillo, Sally D.

Natural processes tend to vary over time and space, as well as between species. The ecosystem services these natural processes provide are therefore also highly variable. It is often assumed that ecosystem services are provided linearly (unvaryingly, at a steady rate), but natural processes are characterized by thresholds and limiting functions. In this paper, we describe the variability observed in wave attenuation provided by marshes, mangroves, seagrasses, and coral reefs and therefore also in coastal protection. We calculate the economic consequences of assuming coastal protection to be linear. We suggest that, in order to refine ecosystem-based management practices, it is …

Introduction To Common Native And Potential Invasive Freshwater Plants In Alaska, Vanessa Howard Morgan, Mark Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Freshwater aquatic plants are found in most lakes and rivers in Alaska. They range from tiny floating plants that can form mats on a lake surface to emergent plants growing two meters above the water. Aquatic plants are an important part of freshwater environments. They provide food and shelter for a wide variety of insects, fish, mammals, and birds; stabilize shorelines; and form an important link in nutrient cycles. To date, Alaska has had relatively few problems with invasive, non-native aquatic plants. However, invasive aquatic plants pose an increasing threat to human safety and the integrity of native aquatic communities. …

Using Community-Based Participatory Evaluation (Cbpe) Methods As A Tool To Sustain A Community Health Coalition, Leslie Aldrich, Daniel Silva, Danelle Marable, Erica Sandman

The Foundation Review

· Participatory evaluation has set the standard for cooperation between program evaluators and stakeholders. Coalition evaluation, however, calls for more extensive collaboration with the community at large.

· Integrating principles of community based participatory research and the Substance Abuse and Mental Health Services Administration’s Strategic Prevention Framework, which guides much coalition work, into coalition evaluation has proved useful to foster community affiliations and support reciprocal relationship building. The resulting evaluation method, named community based participatory evaluation (CBPE), takes time, money, and skilled personnel but can lead to more accurate results and coalition sustainability.

· The CBPE method has proved essential …

Worst Case And The Worst Example: An Agenda For Any Young Lawyer Who Wants To Save The World From Climate Chaos, William H. Rodgers, Jr., Anna T. Moritz

Articles

Wherever you turn with regard to climate change, you'll hear about the worst, and the worst of the worst, and the worst that will happen after that. Young lawyers should put themselves in the right frame of mind to tackle all these "worsts" that are headed our way.

In the interest of keeping it simple, we would suggest a personal strategy for every young lawyer that would entail: (I) Honoring Knowledge and Learning; (II) Protecting Your Institutions and Loving Your Country; (III) Planning and Conducting Your Personal War on Bad Law; and (IV) Rejecting Defeatism and Impossibility Theorems.

Let's consider …

Nps' Perceptions Of Disaster Preparedness Education: Quantitative Survey Research, Milada Tichy, A. Elaine Bond, Renea L. Beckstrand, Barbara Heise

Faculty Publications

Nurse practitioners need to be effective in responding to large-scale natural and man-made disasters. However, disaster core competencies for NPs are largely nonexistent. The purpose of this study was to assess NPs' level of disaster preparedness and determine how NPs acquired knowledge about disaster preparation. Findings suggest that a consistent national NP curriculum for disaster preparedness, including communication with other disaster agencies, is needed. With proper education, NPs can play a major role in disaster management.

A Focus Group Exploration Of Sexual Identity Formation In Nonmonosexual Women, Sarah Christy Daniels

UNF Graduate Theses and Dissertations

Nonmonosexuality invisibility in the scientific literature is explored as well as opposing historical viewpoints of nonmonosexuality's origins and nature. A focus group was used to explore the sexual identities of self-identified nonmonosexual women, their own journeys toward sexual identity formation, and the extent to which society has impacted their ability to express these identities. Using Consensual Qualitative Methodology (C. E. Hill, S. Knox, B. J. Thompson, E. N. Williams, S. A. Hess, & N. Ladany, 2005; C. E. Hill, B. J. Thompson, & E. N. Williams, 1997), several themes emerged: (a) defining one's identity; (b) social consciousness; (c) experiences of …

Vegetation Response To Restoration Treatments In A Former Pine Plantation In North Florida, Ryan C. Meyer

UNF Graduate Theses and Dissertations

As the human population in Florida continues to expand, development follows, and tree farms give way to homes and businesses. As parks are established, restoration of these semi-natural plantations may provide critical habitat for species conservation. This study evaluates vegetation response to restoration treatments at two study sites, formerly tree farms, now preserves in NE Florida. Treatments included thinning, clearing, or control (no treatment) within 10m^2 plots. Thinning reduced tree canopy to 20% (2-3 pines/plot) and removed all other vegetation; clearing treatments removed all biomass to bare soil; no herbicides were used. Within these plots richness and abundance was assessed …

Perceptions And Pedagogy: Exploring The Beliefs And Practices Of An Effective Primary Science Teacher, Angela Fitzgerald, Vaille Dawson, Mark Hackling

Research outputs pre 2011

Effective science teaching is vital for improved student learning outcomes in primary school science. Therefore, there is a need to tease out the components of effective science teaching to better understand what effective primary teachers do in their classrooms and why they do it. Four primary teachers, each nominated as effective science practitioners by a professional colleague, entered into this research study. This 'entry' phase involved gathering information from classroom observations and teacher interviews to provide background information about the beliefs and practices of these teachers. This paper reports on the findings drawn from one teacher - 'Deanne'.

Intensity Of Herbivory On Kelp By Fish And Sea Urchins Differs Between Inshore And Offshore Reefs, Mathew Vanderklift, Paul Lavery, Kris Waddington

Research outputs pre 2011

Interactions between water motion, primary productivity, and herbivory are complex. Rates of grazing by fish on tropical coral reefs and by sea urchins on temperate rocky reefs are usually high, but can be low in areas of extreme water motion. Some herbivores can switch between mobile (grazing) and sedentary (drift-feeding) behaviours, and this can be influenced by water motion. We compared the relative consumption of the kelp Ecklonia radiata at rocky reefs in western Australia with different wave exposures (inshore versus offshore). No herbivory was recorded offshore, suggesting that wave exposure might inhibit herbivory. We also compared grazing by fish …

Interactive Effects Of Timing, Intensity And Duration Of Experimental Shading On Amphibolis Griffithii, Paul Lavery, Kathryn Mcmahon, Michael Mulligan, Andrew Tennyson

Research outputs pre 2011

The responses of the seagrass Amphibolis griffithii to different experimental shading conditions were examined by characterising biomass, morphological and physiological features. In an in situ experiment, the intensity (ambient, moderate shading [13 to 19% of ambient] and high shading [5 to 11% of ambient]), duration (3, 6, 9 mo) and timing (post-summer, post-winter) of light reductions were manipulated. We observed interactive effects of all 3 factors, the most notable being with timing. When moderate shading was imposed at the end of summer there was a 57% loss of leaf biomass and 67% loss of rhizome carbohydrates within 3 mo. The …

Consequences Of Climate-Driven Biodiversity Changes For Ecosystem Functioning Of North European Rocky Shores, Stephen Hawkins, Heather Sugden, Nova Mieszkowska, Philippa Moore, Elvira Poloczanska, Rebecca Leaper, Roger Herbert, Martin Genner, Paula Moschella, Richard Thompson, Stuart Jenkins, Alan Southward, Michael Burrows

Research outputs pre 2011

We review how intertidal biodiversity is responding to globally driven climate change, focusing on long-term data from rocky shores in the British Isles. Physical evidence of warming around the British Isles is presented and, whilst there has been considerable fluctuation, sea surface temperatures are at the highest levels recorded, surpassing previous warm periods (i.e. late 1950s). Examples are given of species that have been advancing or retreating polewards over the last 50 to 100 yr. On rocky shores, the extent of poleward movement is idiosyncratic and dependent upon life history characteristics, dispersal capabilities and habitat requirements. More southern, warm water …

Larvicidal Activity Of Extracts From Three Plumbago Spp Against Anopheles Gambiae, Barasa M. Maniafu, Lwande Wilber, Isaiah O. Ndiege, Cornelius C. Wanjala, Teresa Ayuko Akenga

All Peer-Reviewed Publications

Three Plumbago spp have been tested for mosquito larvicidal activity. The crude extracts exhibiting the highest larvicidal activity against Anopheles gambiae were hexane (LC50 = 6.4 μg/mL) and chloroform (LC50 = 6.7 μg/mL) extracts from Plumbago zeylanica Linn, chloroform (LC50 = 6.7 ug/mL) extract from Plumbago stenophylla Bull and ethyl acetate (LC50 = 4.1 μg/mL) extract from Plumbago dawei Rolfe. These LC50 values were within 95% confidence limits. 5-hydroxy-2-methyl-1,4-naphthoquinone (plumbagin) 1 (LC50 = 1.9 μg/mL) and β-sitosterol 2 were characterised from ethyl acetate extract of root bark of P. dawei, a native medicinal plant growing in Kenya, based on spectral …

Characterization Of Nprc And Its Binding Partners, Abdel A. Alli

USF Tampa Graduate Theses and Dissertations

The C type natriuretic peptide receptor (NPRC) also known as NPR3 is a widely expressed single transmembrane-spanning protein. NPRC functions as a homodimer at the cell surface for the metabolic clearance of a broad range of natriuretic peptides from circulation. The intracellular domain of NPRC is coupled to inhibitory G proteins and is involved in mediating signal transduction. In order to further elucidate the role of NPRC in signal transduction a proteomic approach was taken to identify putative protein binding partners for NPRC in different cell-types. An interrogation of the molecular association between NPRC and its identified protein binding partner(s) …

The Importance Of Benthic Habitats As Reservoirs Of Persistent Fecal Indicator Bacteria, Brian D. Badgley

USF Tampa Graduate Theses and Dissertations

Enterococci are fecal indicator bacteria (FIB) that are used worldwide for water

quality assessment. However, evidence of high densities and extended survival of

enterococci in sediments and submerged aquatic vegetation (SAV) has caused uncertainty

about their reliability in predicting human health risks from recreational activities in

environmental waters. To address the concern that sediments and SAV may harbor large

reservoirs of enterococci that can affect water column concentrations, aquatic mesocosms

and environmental sampling were employed to investigate patterns of enterococci

densities and population structure across the Tampa Bay watershed.

In mesocosm experiments and environmental samples, SAV harbored higher

densities of …
