Green Building Retrofits In A Corporate Setting, Edward M. Snook Jr.

Sustainability and Social Justice

Buildings influence human consumption levels and lifestyles, require resources for creation and operation, and occupy physical space in the environment. This study examines if energy efficient buildings provide sufficient benefits to overcome costs in a certified green building project and the ways that tenants and owners can work together to accomplish retrofit projects and LEED certification in existing buildings. The results of the LEED feasibility analysis demonstrated that the office building studied could achieve Silver or Gold certification with little or no infrastructure and process change cost. Additionally, benefits exist for both the building’s owner and tenant, and costs can …

This research also provided concrete information that brought about change at the classroom …

Garden-Based Learning In Worcester, Massachusetts: Addressing Science And Health Curriculum Gaps Through Summer Youth Programming, Julia Groenfeldt

Sustainability and Social Justice

This research examines the role of experiential garden-based “food citizenship” education for improving school year health and science curriculum retention and to further influence broader social and environmental awareness. Studies demonstrate the importance of these educational models to teach children the processes of food production to consumption. Through new knowledge on food systems education, children will learn to become more mindful and conscious consumers that will ultimately impact personal health outcomes as well as broader global sustainability. Education is a key component to the emerging alternative food network (AFN) that is challenging the modern agro-industrial food system. This research provides …

From Clinging To Digging: The Postembryonic Skeletal Ontogeny Of The Indian Purple Frog, Nasikabatrachus Sahyadrensis (Anura: Nasikabatrachidae), Gayani Senevirathne, Ashish Thomas, Ryan R. Kerney, James Hanken, S. D. Biju, Madhava Meegaskumbura

Biology Faculty Publications

The Indian Purple frog, Nasikabatrachus sahyadrensis, occupies a basal phylogenetic position among neobatrachian anurans and has a very unusual life history. Tadpoles have a large ventral oral sucker, which they use to cling to rocks in torrents, whereas metamorphs possess adaptations for life underground. The developmental changes that underlie these shifts in habits and habitats, and especially the internal remodeling of the cranial and postcranial skeleton, are unknown. Using a nearly complete metamorphic series from free-living larva to metamorph, we describe the postembryonic skeletal ontogeny of this ancient and unique monotypic lineage. The torrent-dwelling larva possesses a dorsoventrally flattened …

Unearthing The Fossorial Tadpoles Of The Indian Dancing Frog Family Micrixalidae, Gayani Senevirathne, Sonali Garg, Ryan R. Kerney, Madhava Meegaskumbura, S. D. Biju

Biology Faculty Publications

Tadpoles of the monotypic Indian dancing frog family Micrixalidae have remained obscure for over 125 years. Here we report the discovery of the elusive tadpoles of Micrixalus herrei from the sand beds of a forested stream in southern Western Ghats, and confirm their identity through DNA barcoding. These actively burrowing tadpoles lead an entirely fossorial life from eggs to late metamorphic stages. We describe their internal and external morphological characters while highlighting the following features: eel-like appearance, extensively muscularized body and tail, reduced tail fins, skin-covered eyes, delayed development of eye pigmentation in early pre-metamorphic stages (Gosner stages 25–29), prominent …

Analysis Of The Invasiveness Of Cabomba Caroliniana A. Gray In Massachusetts And Rhode Island Freshwater Lakes And Assessment Of The Impacts Of Local Community Action Groups On Ais Management And Intervention Programs, Nicole Cournoyer

Master of Science in Global Environmental Studies

Native to parts of South America and southeastern United States, Cabomba caroliniana A. Gray is an invasive aquatic pondweed species that has migrated to northern regions of the United States. C. caroliniana is known for its rapid growth pattern and its ability to dominate freshwater ecosystems. The overgrowth of this invasive species is difficult to manage, with few effective eradication/control methods available. Dense hairs and crystals found upon the leaf surfaces are believed to enhance the ability of Carolina fanwort to survive in a wide variety of ecosystems. Management of this particular species requires an active approach. This study explored …

Ecosystem Services In Managing Residential Landscapes: Priorities, Value Dimensions, And Cross-Regional Patterns, Kelli L. Larson, Jennifer L. Morse, Peter M. Groffman, Neil D. Bettez, Tara Trammell

Environmental Science and Management Faculty Publications and Presentations

Although ecosystem services have been intensively examined in certain domains (e.g., forests and wetlands), little research has assessed ecosystem services for the most dominant landscape type in urban ecosystems—namely, residential yards. In this paper, we report findings of a cross-site survey of homeowners in six U.S. cities to 1) examine how residents subjectively value various ecosystem services, 2) explore distinctive dimensions of those values, and 3) test the urban homogenization hypothesis. This hypothesis posits that urbanization leads to similarities in the social-ecological dynamics across cities in diverse biomes. By extension, the thesis suggests that residents’ ecosystem service priorities for residential …

Mechanisms Of Methane Transport Through Populus Trichocarpa, Ellynne Marie Kutschera, M. A. K. Khalil, Andrew Rice, Todd Rosenstiel

Physics Faculty Publications and Presentations

Although the dynamics of methane (CH4) emission from croplands and wetlands have been fairly well investigated, the contribution of trees to global CH4 emission and the mechanisms of tree transport are relatively unknown. CH4 emissions from the common wetland tree species Populus trichocarpa (black cottonwood) native to the Pacific Northwest were measured under hydroponic conditions in order to separate plant transport mechanisms from the influence of soil processes. Roots were exposed to CH4 enriched water and canopy emissions of CH4 were measured. The average flux for 34 trials (at temperatures ranging from 17 to 25 °C) was 2.8 ± 2.2 …

Re-Building Coal Country: A Church/University Partnership, Carl Milofsky, Brandn Green

Faculty Journal Articles

This paper describes a developing partnership between a church-based service learning center and a university initiative to build a field station in a low-income community in the anthracite coal region of Pennsylvania. It is a case study of how secular and religious institutions have been collaborating to achieve the shared goal of improving social conditions in specific communities. The theoretical focus of the paper is on how a change from a “glass is half empty” to a “glass is half full” perception of the community opens new possibilities for change. This paper concentrates on the story of one partnership as …

Estimation Of Large Dimensional Factor Models With An Unknown Number Of Breaks, Shujie Ma, Liangjun Su

Research Collection School Of Economics

In this paper we study the estimation of a large dimensional factor model when the factor loadings exhibit an unknown number of changes over time. We propose a novel three-step procedure to detect the breaks if any and then identify their locations. In the first step, we divide the whole time span into subintervals and fit a conventional factor model on each interval. In the second step, we apply the adaptive fused group Lasso to identify intervals containing a break. In the third step, we devise a grid search method to estimate the location of the break on each identified …

Advanced Science Research Center

Residential yards across the US look remarkably similar despite marked variation in climate and soil, yet the drivers of this homogenization are unknown. Telephone surveys of fertilizer and irrigation use and satisfaction with the natural environment, and measurements of inherent water and nitrogen availability in six US cities (Boston, Baltimore, Miami, Minneapolis-St. Paul, Phoenix, Los Angeles) showed that the percentage of people using irrigation at least once in a year was relatively invariant with little difference between the wettest (Miami, 85%) and driest (Phoenix, 89%) cities. The percentage of people using fertilizer at least once in a year also ranged …
