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.

How To Enhance Interdisciplinary Competence—Interdisciplinary Problem-Based Learning Versus Interdisciplinary Project-Based Learning, Mirjam Brassler, Jan Dettmers Jul 2017

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 …

Time Varying Parameter Models For Catchments With Land Use Change: The Importance Of Model Structure, Sahani Pathiraja, Daniela Anghileri, Paolo Burlando, Ashish Sharma, Lucy Marshall, Hamid Moradkhani

Civil and Environmental Engineering Faculty Publications and Presentations

Rapid population and economic growth in South-East-Asia has been accompanied by extensive land use change with consequent impacts on catchment hydrology. Modelling methodologies capable of handling changing land use conditions are therefore becoming ever more important, and are receiving increasing attention from hydrologists. A recently developed Data Assimilation based framework that allows model parameters to vary through time in response to signals of change in observations is considered for a medium sized catchment (2880 km²) in Northern Vietnam experiencing substantial but gradual land cover change. We investigate the efficacy of the method as well as the importance of the chosen …

Passenger Satisfaction And Mental Adaptation Under Adverse Conditions: Case Study In Manila, Andra Charis Mijares, Mio Suzuki, Tetsuo Yai

Journal of Public Transportation

Public transportation systems in several developing cities face congestion, air pollution, and safety problems, yet many passengers use them regularly. This study examines the structure of passenger satisfaction and the role of mental adaptation under such conditions. Metro Manila MRT-3 was analyzed as a case study.

The actual and perceived conditions at the MRT-3 were assessed using surveys. Results of the waiting time and PM2.5 monitoring surveys revealed that passengers queue for 30 minutes, on average, while being exposed to unsafe levels of PM2.5. The questionnaire survey results show some discrepancies between actual and perceived values, suggesting …

The Next Billion: Lessons In Off-Grid Electricity Development From The Global South, Peter Mcdonough Jan 2016

The Next Billion: Lessons In Off-Grid Electricity Development From The Global South, Peter Mcdonough

Graduate Student Theses, Dissertations, & Professional Papers

Today about a third of the world’s population has no access to electricity, and another third has only limited access. Driven by the push for development on one hand and the reality of climate change on the other, a combination of for-profit companies, NGOs, missions, and aid organizations is looking for the silver bullet to sustainable electricity development. In order to understand the challenges facing off-grid electricity projects I used recent literature in the form of peer-reviewed journals, agency reports, news articles, and technical documents; stakeholder interviews; and on-site observations in selected case studies in Nepal, India, and Tanzania. In …

Life Cycle Assessment (Lca) Of Tourism Activities, Kayla Santello

Honors Theses and Capstones

Abstract— Tourism, like other developed industries is a commerce that requires energy inputs and yields outputs with significant effects on the environment. However a comprehensive study examining the life cycle impact associated with each tourism component including transportation, accommodation, food services, and recreation is still lacking. Therefore a search of previous tourism life cycle studies was carried out and ten studies were further investigated. Indicators, assessment approaches, and system boundaries of these previous studies were assessed. Then the outcomes were normalized and compared in order to obtain ranges for the four components of tourism. It was found that energy intensity …
