Geographies Of Transition—From Topical Concerns To Theoretical Engagement: A Commentary On The Transitions Research Agenda, Christian Binz, Lars Coenen, James T. Murphy, Bernhard Truffer Mar 2020

Geographies Of Transition—From Topical Concerns To Theoretical Engagement: A Commentary On The Transitions Research Agenda, Christian Binz, Lars Coenen, James T. Murphy, Bernhard Truffer

Geography

This viewpoint takes stock with the ‘geography of sustainability transitions’ (GOST) as it is presented in the transitions research agenda. GOST has been a relatively recent addition to transition theorizing, addressing the need for greater sensitivity and attention to the scales, spatialities, and context-specific factors that shape transitions. In our view, the agenda represents a rather narrow perspective on GOST, which is geared to two empirical themes, namely urban transitions and transitions in developing countries. While these are relevant and topical issues, the section lacks sufficient acknowledgement of the increasing engagement of geographers with transitions studies and the theoretical approaches …

Ecojustice, Religious Folklife And A Sound Ecology, Jeff Todd Titon Feb 2020

Ecojustice, Religious Folklife And A Sound Ecology, Jeff Todd Titon

Yale Journal of Music & Religion

Folk, traditional, and indigenous ecological knowledges have a significant role to play in ecojustice. A case study in the traditional ecological knowledge among one of the religious communities with whom I have spent several decades illustrates how they embody the main principle and three fields of an ecological rationality: the community of inter-related beings; the ways the beings participate in that community or place; and the relations of nature and the nonhuman world to humans and human nature. Ecological rationality stands in contrast to economic rationality, a branch of instrumental reason exemplified by what economists call rational choice theory. An …

Salt Marsh Monitoring Along The Mid-Atlantic Coast By Google Earth Engine Enabled Time Series, Anthony D. Campbell, Yeqiao Wang

Natural Resources Science Faculty Publications

Salt marshes provide a bulwark against sea-level rise (SLR), an interface between aquatic and terrestrial habitats, important nursery grounds for many species, a buffer against extreme storm impacts, and vast blue carbon repositories. However, salt marshes are at risk of loss from a variety of stressors such as SLR, nutrient enrichment, sediment deficits, herbivory, and anthropogenic disturbances. Determining the dynamics of salt marsh change with remote sensing requires high temporal resolution due to the spectral variability caused by disturbance, tides, and seasonality. Time series analysis of salt marshes can broaden our understanding of these changing environments. This study analyzed aboveground …

Crustal Composition And Moho Variations Of The Central And Eastern United States: Improving Resolutionand Geologic Interpretation Of Earthscope Usarray Seismic Images Using Gravity, H. L. Zhang, D. Ravat, Anthony R. Lowry Feb 2020

Crustal Composition And Moho Variations Of The Central And Eastern United States: Improving Resolutionand Geologic Interpretation Of Earthscope Usarray Seismic Images Using Gravity, H. L. Zhang, D. Ravat, Anthony R. Lowry

Geosciences Faculty Publications

EarthScope's USArray Transportable Array has shortcomings for the purpose of interpreting geologic features of wavelengths less than the Transportable Array station spacing, but these can be overcome by using higher spatial resolution gravity data. In this study, we exploit USArray receiver functions to reduce nonuniqueness in the interpretation of gravity anomalies. We model gravity anomalies from previously derived density variations of sedimentary basins, crustal Vp/Vs variation, Moho variation, and upper mantle density variation derived from body wave imaging informed by surface wave tomography to estimate Vp/Vs. Although average densities and density contrasts for …

Estimation Of Available Epinephrine Dose In Expired And Discolored Autoinjectors Via Quantitative Smartphone Imaging, Amirus Saleheen, Bill M. Campbell, Rebecca A. Prosser, Christopher A. Baker Feb 2020

Estimation Of Available Epinephrine Dose In Expired And Discolored Autoinjectors Via Quantitative Smartphone Imaging, Amirus Saleheen, Bill M. Campbell, Rebecca A. Prosser, Christopher A. Baker

United States National Park Service: Publications

Epinephrine autoinjectors (EAIs) are important first aid medications for treating anaphylaxis. A 10-fold price increase over the past 12 years and evidence that expired EAIs may still contain significant doses of available epinephrine have motivated interest in the efficacy of expired EAIs as treatments of last resort. Degradation of expired EAIs, which can be caused by improper storage conditions, results in various degrees of discoloration of the epinephrine solution. Previous studies have determined that significant epinephrine remains available in expired EAIs, but these have only considered EAIs that show no discoloration. Here, we investigate the potential for colorimetric estimation of …

Communal Land Tenure Security For Widows In The Eenhana Constituency Of The Ohangwena Region, Namibia, Ndapewa F. Nakanyete, Romie V. Nghitevelekwa, Mark M. Matsa, John Mendelsohn, Selma Lendelvo, Fanuel Shikale

Journal of International Women's Studies

Namibia is characterized by a history of discriminatory customary practices against women with regards to access to land, rights over land, and security of land tenure. Since independence in 1990, the country has adopted policies and legislative frameworks to bring about gender equality in all spheres of life, including the transformation of land tenure rights. These policies and acts give effect to the constitutional provisions that accord both men and women equal opportunities for access to land, rights over land and security of tenure. Widows are a particularly singled-out social group for legal protection, land security and rights to land …

Effects Of Culling White-Tailed Deer On Tree Regeneration And Microstegium Vimineum, An Invasive Grass, John Paul Schmit, Elizabeth R. Matthews, Andrejs Brolis Feb 2020

Effects Of Culling White-Tailed Deer On Tree Regeneration And Microstegium Vimineum, An Invasive Grass, John Paul Schmit, Elizabeth R. Matthews, Andrejs Brolis

United States National Park Service: Publications

Reduction of forest regeneration due to overbrowsing by white-tailed deer is a growing concern for land managers. Abundant deer can impede forest regeneration through direct predation on tree seedlings. Additionally high deer density can facilitate the establishment of a dense understory of browse tolerant plant species that shades seedlings and persists even in the absence of deer. In response to these challenges, land managers have sought to reduce deer herds to restore tree regeneration, but few studies have evaluated the effectiveness of this management. Our study took place in Catoctin Mountain Park, a US National Park Service unit with a …

Nurse Rock Microclimates Significantly Buffer Exposure To Freezing T Temperature And Moderate Summer Temperature, Joshua L. Conver, Elliott Yarwood, Lucas D. Hetherington, Don E. Swann

United States National Park Service: Publications

Nurse tree canopies mitigate exposure to freezing temperatures that could result in injury or mortality to the saguaro cactus (Carnegiea gigantea). Abiotic objects have been hypothesized to provide similar beneficial microclimates. We used data loggers at 11 nurse rock sites to record daily daytime summer maximum and winter nighttime minimum temperatures at Saguaro National Park, Arizona, to examine the effectiveness of rocks to moderate seasonal temperature extremes in the microclimate. Temperatures at rock sites averaged 2 °C warmer than exposed open control sites in winter. We found that the efficiency of rocks to act as insulators significantly increased as temperature …
