Stress-Related Growth In Two Challenging Conditions, Iva Solcova, Peter Tavel

Journal of Human Performance in Extreme Environments

In the last few years, attention has been given not only to negative impacts of stressful conditions but also to possible positive outcomes. The present study was devoted to personal growth in two challenging conditions in two samples of participants coming from different nations and different cultural backgrounds. The study extends existing knowledge by more intimate insight into the different facets of social and cognitive/affective personal growth. The experience of personal growth was individualized as far as the number of changes, their intensity, and facets/items in which the changes occurred.

Least affected was the spirituality area. The reason is probably …

Building Student Capacity To Lead Sustainability Transitions In The Food System Through Farm-Based Authentic Research Modules In Sustainability Sciences (Farms), Selena Ahmed, Alexandra Sclafani, Estephanie Aquino, Shashwat Kala, Louise Barias, Jaime Eeg

Dartmouth Scholarship

Undergraduate courses provide valuable opportunities to train and empower students with the knowledge, skills, and motivation to advance society in more sustainable directions. This article emphasizes the value of bridging primary scientific research with undergraduate education through the presentation of an integrated experiential learning and primary research model called Farm-based Authentic Research Modules in Sustainability Sciences (FARMS). FARMS are collaboratively designed with agricultural stakeholders through a community needs assessment on pressing food system issues and opportunities with the objective for faculty and students to jointly identify evidence-based management solutions. We illustrate the implementation of FARMS in an undergraduate course in …

Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Miombo Woodlands of Tanzania comprise several habitat types that are home to a great number of flora and fauna. Understanding their responses to increasing human disturbance is important for conservation, especially in places where people depend so directly on their local ecosystem services to survive. Soundscapes are a powerful approach to study complex biomes undergoing change. The sounds emitted by soniferous fauna characterize the acoustic profile of the landscapes they inhabit such that habitats with the highest acoustic abundance are considered as the most diverse and possibly more ecologically resilient. However, acoustic variability within similar habitat types may pose …

How Governmental Greenhouse Gas Science Has Been Weathered Through Time And Why It Matters, Christopher Apple

STAR Program Research Presentations

Global consumption of materials and energy is accelerating. The rate of plant and animal species extinction is accelerating. On a finite Earth with a growing population, current consumption cannot continue sustainably. Greenhouse gases (GHGs) tell us an important part of this story. The Global Greenhouse Gas Reference Network, managed by scientists at NOAA’s Earth System Research Laboratory, is the largest greenhouse gas analysis network in the world. It has been shaped by scientific questions, stagnant funding despite rises in research costs, and the task of understanding how the Earth system will respond to a changing climate. The Network began by …

A Moment Became The Season: An Exploration Of Trauma Narrative Within The Community Development Context, Lydia Berry

Sustainability and Social Justice

This research explores current methods of psychological trauma intervention within the community development context, namely the understandings that bound the clinical and diagnostic side of trauma, and the more recent victim centered approach: the trauma informed care method. The shortcomings of these approaches is that they individually lack the ability to establish the victim back into their sense of self or community, accordingly. This research argues that a narrative approach, a process by which a survivor of trauma has full agency to express their experience, used in conjunction with existing practices can rectify the shortcomings of both methods. The researcher …

Exploring The Empirical Relationship Between Civic Agriculture And Community Resilience, Beth Joanna Person-Michener

Graduate Theses and Dissertations

Smaller-scale, qualitative and mixed method studies indicate that civic agriculture generates positive, local-level social change, specifically by increasing social, human and economic capital. These social benefits are also identified as some of the crucial components needed for community resilience to disasters. However, literature directly linking civic agriculture to community resilience is sparse and there is little if any research explicitly examining a relationship between civic agriculture and community resilience. This study lends national scope and an empirical examination of evidence for a positive relationship between civic agriculture and community resilience along the applicable domains of social, human and economic capital …

Spatial Models To Account For Variation In Observer Effort In Bird Atlases, Andrew M. Wilson, Daniel W. Brauning, Caitlin Carey, Robert S. Mulvihill

Environmental Studies Faculty Publications

To assess the importance of variation in observer effort between and within bird atlas projects and demonstrate the use of relatively simple conditional autoregressive (CAR) models for analyzing grid-based atlas data with varying effort. Pennsylvania and West Virginia, United States of America. We used varying proportions of randomly selected training data to assess whether variations in observer effort can be accounted for using CAR models and whether such models would still be useful for atlases with incomplete data. We then evaluated whether the application of these models influenced our assessment of distribution change between two atlas projects separated by twenty …

Benefits Of Reduced Meat Consumption In The U.S.: Cost-Benefit Analysis Of An Increase In Plant-Based Diets, Rebecca Zahora

Senior Honors Projects

How sustainable is our food system? An investigation of diet choices and their environmental impacts

Food is often thought of as a commodity, when fundamentally it is our nourishment and foundation of life. In the United States, it appears as if we have a functional food system, but in reality what we have is an unsustainable system of industrialized agriculture perpetuated by a disproportionate allocation of resources. Current consumer behavior within our food system is detrimental to future environmental and human well being, ultimately exacerbating the timing and magnitude of global climate change.

With negative impacts of climate change looming …

Through a case study of the Lower Ninth Ward in New Orleans this research reviews five residential rebuilding programs to see if its goals were written equitably. This research then compares the Lower Ninth Ward with the entire City of New Orleans as well as two other planning …

How To Enhance Interdisciplinary Competence—Interdisciplinary Problem-Based Learning Versus Interdisciplinary Project-Based Learning, Mirjam Brassler, Jan Dettmers

Interdisciplinary Journal of Problem-Based Learning

Interdisciplinary competence is important in academia for both employability and sustainable development. However, to date, there are no specific interdisciplinary education models and, naturally, no empirical studies to assess them. Since problem-based learning (PBL) and project-based learning (PjBL) are learning approaches that emphasize students’ collaboration, both pedagogies seem suitable to enhance students’ interdisciplinary competence. Based on the principle of constructive alignment and four instructional principles on interdisciplinary learning, this paper proposes that students profit more from interdisciplinary PBL (iPBL) than interdisciplinary PjBL (iPjBL). A pre-post study was conducted with a sample of 95 students participating in iPBL and 183 students …

Synergistic Use Of Remote Sensing And Modeling To Assess An Anomalously High Chlorophyll-A Event During Summer 2015 In The South Central Red Sea, Wenzhao Li, Hesham El-Askary, K. P. Manikandan, Mohamed A. Qurban, Michael J. Garay, Olga V. Kalishnikova

Mathematics, Physics, and Computer Science Faculty Articles and Research

An anomalously high chlorophyll-a (Chl-a) event (>2 mg/m3) during June 2015 in the South Central Red Sea (17.5° to 22°N, 37° to 42°E) was observed using Moderate Resolution Imaging Spectroradiometer (MODIS) data from the Terra and Aqua satellite platforms. This differs from the low Chl-a values (<0.5 mg/m3) usually encountered over the same region during summertime. To assess this anomaly and possible causes, we used a wide range of oceanographical and meteorological datasets, including Chl-a concentrations, sea surface temperature (SST), sea surface height (SSH), mixed layer depth (MLD), ocean current velocity and aerosol optical depth (AOD) obtained from different sensors and models. Findings confirmed this anomalous behavior in the spatial domain using Hovmöller data analysis techniques, while a time series analysis addressed monthly and daily variability. Our analysis suggests that a combination of factors controlling nutrient supply contributed to the anomalous phytoplankton growth. These factors include horizontal transfer of upwelling water through eddy circulation and possible mineral fertilization from atmospheric dust deposition. Coral reefs might have provided extra nutrient supply, yet this is out of the scope of our analysis. We thought that dust deposition from a coastal dust jet event in late June, coinciding with the phytoplankton blooms in the area under investigation, might have also contributed as shown by our AOD findings. However, a lag cross correlation showed a two- month lag between strong dust outbreak and the high Chl-a anomaly. The high Chl-a concentration at the edge of the eddy emphasizes the importance of horizontal advection in fertilizing oligotrophic (nutrient poor) Red Sea waters.

Differential Use Of Two Warm-Water Effluents By The Florida Manatee (Trichechus Manatus Latirostris) And Temporal Distributions Throughout Broward County, Florida, Laura F. Eldredge

HCNSO Student Theses and Dissertations

The threatened Florida manatee (Trichechus manatus latirostris) migrates seasonally to warm-water refugia throughout the state of Florida due to metabolic requirements from low thermal conductance. Broward County’s two power plant refugia, Port Everglades (PEP) and Lauderdale (LPP), are known heavily-utilized aggregation sites for the Atlantic sub-population. Broward County collected relative abundance counts via aerial surveys from 2004–2013 siting 31,418 manatees during 169 surveys within 18 defined waterway zones. Counts during manatee wintering seasons were significantly different from January 2005-March 2008 and November 2008-March 2013, likely related to flight path and frequency standardization. Mean percentage of adults (90.12%) to …

This dissertation examines spatial and temporal impacts of natural resource use. The second chapter integrates hydrological and economic systems to examine the impact of drought on these two systems and explores the spatial impact of policies aimed to mitigate the drought impact. The systems dynamics model developed for this chapter simultaneously considers the physical hydrology in the Middle Rio Grande water basin in New Mexico, the engineered water management system, and a behavioral model of residential water demand for three cities: Albuquerque, Rio Rancho, and Santa Fe, New Mexico. The simulation results showed that droughts that occur in later periods, …

The Long-Term Effect Of State Renewable Energy Incentive Programs, Fred Bower

Journal of Environmental and Resource Economics at Colby

Abstract: Renewable energy is praised for its environmental benefits and long run energy savings, however, for the average consumer, the up-front cost of this infrastructure deters investment. On the Federal and state level, incentive programs have been implemented to break down these initial barriers and give easier access to renewable energy. Studies have shown that these incentive programs have been successful at the consumer level (Crago, 2014). What policy makers and government officials should maybe be more concerned with though, is the long-term effect of these programs. This paper will analyze the long-term effect of renewable energy incentive programs beyond …

Bending The Carbon Curve: Fire Management For Carbon Resilience Under Climate Change, E. Louise Loudermilk, Robert M. Scheller, Peter J. Weisberg, Alec M. Kretchun

Environmental Science and Management Faculty Publications and Presentations

Context: Forest landscapes are increasingly managed for fire resilience, particularly in the western US which has recently experienced drought and widespread, high-severity wildfires. Fuel reduction treatments have been effective where fires coincide with treated areas. Fuel treatments also have the potential to reduce drought-mortality if tree density is uncharacteristically high, and to increase long-term carbon storage by reducing high-severity fire probability.

Objective: Assess whether fuel treatments reduce fire intensity and spread and increase carbon storage under climate change.

Methods: We used a simulation modeling approach that couples a landscape model of forest disturbance and succession with an ecosystem model of …

Urban Connections: A Comparison Of Connectivity Assessment Methods, Natalie M. Rogers

Environmental Science and Management Professional Master's Project Reports

Habitat connectivity in urban settings is critical for facilitation of safe species movement, species health, and biodiversity. Predicting the movement of wildlife through the urban environment is difficult due to the presence of barriers - natural or built features in the landscape that restrict or prohibit movement of species. Urban properties and greenspaces can serve as pathways of connectivity for wildlife movement across the complex developed matrix. Thus, land managers should assess their properties for possible connectivity functionality to promote safe wildlife movement. Land managers may not be aware of current connectivity assessment methods, therefore this project provides introductory information …
