International Journal of Speleology
The Porto settlement (Northwest Portugal, Iberian Peninsula) was originally built in the twelfth century and has been developed on granitic hill slopes of the Douro riverside, being one of the oldest cities in Europe. In the urban area of Porto, the second most important city of the Portuguese mainland, there is a population of about 216,000 inhabitants. This study highlights the importance of urban speleological mapping applied to groundwater and geo-engineering studies. All the water that flows from the so-called Paranhos or Arca D’Água springs is captured by catchwork galleries and their utilization date back around 1120 AD. Paranhos spring …

The Effect Of Land Use On Stream Water Quality In San Luis And Cañitas, November 2009, Anna Stuart Burnett
The Effect Of Land Use On Stream Water Quality In San Luis And Cañitas, November 2009, Anna Stuart Burnett
Monteverde Institute: Tropical Ecology and Conservation
Human altered landscapes often have significant impacts on water quality in their respective watersheds. However, in order to create policy and educate people about better land use practices, it is necessary to have a thorough understanding of the effects of land use on stream water quality. This study looks at the health of stream water in three streams flowing through different land uses – forest, cattle pasture, and coffee – in San Luis and Cañitas in the Monteverde area. Water quality was determined using biotic and abiotic indicators. The abiotic indicators included dissolved oxygen, temperature, nitrogen, phosphorus, pH, and turbidity. …

Sugar Ethanol In Florida: Economic, Agricultural, And Environmental Aspects, Joshua F. Berger
Sugar Ethanol In Florida: Economic, Agricultural, And Environmental Aspects, Joshua F. Berger
USF Tampa Graduate Theses and Dissertations
Ethanol production has been widely perceived as a solution to the global energy crisis, with the added benefit of reinvigorating declining agricultural economies. Moves towards dedicating crop production to ethanol however have raised a number of concerns related to its economic and environmental consequences. Missing from this debate is a consideration of the ways in which sugar can be used as a feedstock for ethanol, an issue that is especially pertinent within the state of Florida. The national commitment and scale of corn ethanol production in the U.S. has largely meant a lack of focus on other feedstocks which could …

Integration With Writing Programs: A Strategy For Quantitative Reasoning Program Development, Nathan D. Grawe, Carol A. Rutz
Integration With Writing Programs: A Strategy For Quantitative Reasoning Program Development, Nathan D. Grawe, Carol A. Rutz
Numeracy
As an inherently interdisciplinary endeavor, quantitative reasoning (QR) risks falling through the cracks between the traditional “silos” of higher education. This article describes one strategy for developing a truly cross-campus QR initiative: leverage the existing structures of campus writing programs by placing QR in the context of argument. We first describe the integration of Carleton College’s Quantitative Inquiry, Reasoning, and Knowledge initiative with the Writing Program. Based on our experience, we argue that such an approach leads to four benefits: it reflects important aspects of QR often overlooked by other approaches; it defuses the commonly raised objection that QR is …

A Comparative Study Of Environmental Attitudes In 9-12th Grade Students In Monteverde, Costa Rica And Edina, Minnesota, May 2009, Brian Curran
Monteverde Institute: Tropical Ecology and Conservation
In this study a 44-question environmental attitudes survey was given to 150 students in area schools in Monteverde, Costa Rica and Edina, Minnesota. 66 students were sampled from five schools in Monteverde and 94 students were sampled from one high school in Minnesota. The question that was addressed was whether or not: demographic, geographic, curricular, and type of school differences could explain trends in environmental attitude preferences of students that were surveyed. Statistically significant difference trends were found in questions: 4,8,12,16 and 23. However, the survey did not try to correlate demographic variables like income or level of parental education …
The Effects Of Farming Practices On Nectar Quality And Quantity In Coffea Spp, May 2009, Jennifer Carter
The Effects Of Farming Practices On Nectar Quality And Quantity In Coffea Spp, May 2009, Jennifer Carter
Monteverde Institute: Tropical Ecology and Conservation
In the developing world traditional low-input farming practices are being replaced with high-input practices as a way to increase yield. The environmental and economic impact of inputs has driven researchers to seek ways to minimize inputs while maximizing crop yields. In some crops, like Coffea spp., pollination plays an important role in yield. The purpose of this experiment is to compare nectar quality and quantity of Coffea flowers between low-input and high-input farms, demonstrating a link between practices, pollination, and crop yield. I found that more traditional, low-input practices have higher sugar concentration than high-input practices (t = 2.82; p …

“Why Are We Learning This?”: Does Studying The Holocaust Encourage Better Citizenship Values?, Henry Maitles
Genocide Studies and Prevention: An International Journal
The relationship between learning about the Holocaust and the development of positive values may seem common sense, but in reality there is a complex level of development and understanding. The research reported here, which was sponsored by the Scottish government, was designed to ascertain whether learning about the Holocaust has an impact on young people’s general citizenship values and attitudes; does learning about the Holocaust allow them to extrapolate from the events of the Holocaust to present-day issues, such as racism and discrimination? The study followed a cohort of approximately 100 pupils (aged 11–12) who had studied the Holocaust and …

Travel Demand Management: Lessons For Malaysia, Jeyapalan Kasipillai, Pikkay Chan
Journal of Public Transportation
The growth in the number of motor vehicles has exacted costs on both the Malaysian economy and environment. For reasons such as increasing disposable incomes and poor management of the public transportation system, the number of vehicles has grown unabated and, in fact, is aided by various contradictory policy measures such as national car projects and the existence of fuel subsidies. A phased, five-pronged Transport Development Management-based approach is recommended towards targeting a sustainable transportation system in Malaysia: (1) alteration of charges on road taxes and car insurance, (2) elimination of fuel subsidies, (3) imposition of fuel taxes and amendments …
Species Richness Of Vascular Plants In The Riparian Transition Zones Of The Quebrada La Cruz And The Quebrada Socorro In Monteverde, Costa Rica, August 2008, Rhiannon Cook
Monteverde Institute: Tropical Ecology and Conservation
While many studies have been performed to determine the effects of urbanization in the later stages of development on biodiversity, little is known about how biodiversity is affected by urbanizations in its early phases. This research evaluates how the biodiversity of herbaceous plants in the riparian ecotones of two rivers is affected in the transition from a rural to town setting. Morpho species diversity was sampled on two rivers of the Monteverde, Costa Rica area; the Quebrada Socorro, relatively unaffected by human influence, and the Quebrada La Cruz, which is greatly influenced by both the growth of town infrastructure and …
Investigating Environmental Change Due To Hypoxic Conditions On The Louisiana Continental Shelf: A Geochemical Approach, Marianne E. Dietz
Investigating Environmental Change Due To Hypoxic Conditions On The Louisiana Continental Shelf: A Geochemical Approach, Marianne E. Dietz
USF Tampa Graduate Theses and Dissertations
The Louisiana (LA) shelf is chronically affected by seasonal hypoxia that has been shown to be spatially expanding and growing progressively more severe. Hypoxic conditions on the shelf have been closely linked to the large quantities of nutrients delivered to the Gulf of Mexico via the Mississippi River. Multiple geochemical proxies on a suite of sediment cores from the LA shelf provide a record of environmental change that parallels the onset of hypoxic conditions over the last century and prior to anthropogenic influences. The sedimentary record for the last century shows a shift from terrestrial to algal sources to the …

Word Problems: Reflections On Embedding Quantitative Literacy In A Calculus Course, Gizem Karaali
Numeracy
Even though Quantitative Literacy (QL) programs are currently being developed and implemented in several colleges and universities, most schools still depend on traditional mathematics courses to reach their quantitative literacy goals. This note is a case study of how a traditional mathematics course sequence intended for students majoring in social and life sciences may be modified and adapted to at least partially fulfill the need in the absence of a stand-alone QL program. In particular, we focus on a freshman-level mathematics course sequence that serves various client departments. This sequence covers the traditional content of a first-year calculus sequence along …

Quantitative Literacy Across The Curriculum: A Case Study, Benjamin Steele, Semra Kiliç-Bahi
Numeracy
We describe a quantitative literacy (QL) program at Colby-Sawyer College, a small, residential, liberal arts college in New Hampshire. This program has grown rapidly from a traditional math curriculum to a college-wide understanding of quantitative literacy and voluntary participation by many faculty members in all departments. More than 80% of the faculty agreed that it would be useful for students to be able to use quantitative skills in their courses, but only 24 % thought students were capable of doing very well in mathematics. Twenty-three faculty members attended a summer workshop, funded by NSF, DUE # 0633133, in which they …

Quantifying Soil Organic Carbon (Soc) In Wetlands Impacted By Groundwater Withdrawals In West-Central Florida, Katherine Moore Powell
Quantifying Soil Organic Carbon (Soc) In Wetlands Impacted By Groundwater Withdrawals In West-Central Florida, Katherine Moore Powell
USF Tampa Graduate Theses and Dissertations
Saturated for most of the year, wetlands accumulate large amounts of biomass in thick organic soil horizons with slow rates of decomposition due to anaerobic conditions. Wetland soils thereby sequester large amounts of organic carbon in relative long-term storage. Municipal water demands in west-central Florida are largely met through extensive groundwater pumping. These withdrawals can impact ecosystems dependent on surface water levels that are ultimately linked to confined aquifers. Soils in a subset of cypress swamps that are monitored by the Southwest Florida Water Management District (SWFWMD) were sampled and analyzed to ascertain the health of the wetlands impacted by …
Implementing A Native Medicinal Plant Garden In Monteverde, Costa Rica, May 2008, Cory Howes
Implementing A Native Medicinal Plant Garden In Monteverde, Costa Rica, May 2008, Cory Howes
Monteverde Institute: Tropical Ecology and Conservation
The importance of plants has played a powerful role for medicine throughout human history. Tribes in Costa Rica once practiced Shamanism with native flora, but European settlement in the 15th and 16th centuries brought disease, killing much of the aborigines. With their loss, vast amounts of information had been lost regarding what plants they used for medicine. By implementing a garden at the Estación Biológica Monteverde in Monteverde, Costa Rica, an educational tool is created to give students first hand knowledge of 30 native medicinal plants found in Costa Rica. A booklet on the 30 plants was developed to educate …
Evaluating Costa Rica’S Program For Environmental Services Payments In The Monteverde Region, May 2008, Nathaniel F. Meyer
Evaluating Costa Rica’S Program For Environmental Services Payments In The Monteverde Region, May 2008, Nathaniel F. Meyer
Monteverde Institute: Tropical Ecology and Conservation
Costa Rica’s environmental services payments or “PSA” (“Pagos por servicios ambientales”) program was created to provide an economic incentive for landowners to conserve forest, thus compensating them for the ecosystem services their conservation activities provide. This study was conducted to evaluate the program’s performance twelve years after its inception. By interviewing 20 private landowners in the Monteverde region, I ask (1) whether certain demographic parameters or property size affect participation, (2) whether the government is effectively informing farmers of the PSA opportunity, (3) what obstacles are preventing potential participants from successfully obtaining contracts, and (4) whether the program is functioning …
Downscaling Thermal Infrared Radiance For Subpixel Land Surface Temperature Retrieval, Desheng Liu, Ruiliang Pu
Downscaling Thermal Infrared Radiance For Subpixel Land Surface Temperature Retrieval, Desheng Liu, Ruiliang Pu
School of Geosciences Faculty and Staff Publications
Land surface temperature (LST) retrieved from satellite thermal sensors often consists of mixed temperature components. Retrieving subpixel LST is therefore needed in various environmental and ecological studies. In this paper, we developed two methods for downscaling coarse resolution thermal infrared (TIR) radiance for the purpose of subpixel temperature retrieval. The first method was developed on the basis of a scale-invariant physical model on TIR radiance. The second method was based on a statistical relationship between TIR radiance and land cover fraction at high spatial resolution. The two methods were applied to downscale simulated 990-m ASTER TIR data to 90-m resolution. …
Effects Of Zn Doping And High Energy Ball Milling On The Photocatalytic Properties Of Tio2, Paula C. Algarin
Effects Of Zn Doping And High Energy Ball Milling On The Photocatalytic Properties Of Tio2, Paula C. Algarin
USF Tampa Graduate Theses and Dissertations
TiO2 photocatalysis is been widely studied for air and water purification applications; titanium dioxide is the most used semiconductor principally because its low cost, stability and chemical properties. However it only utilizes the UV portion of the solar spectrum as an energy source (less than 4% of the total sunlight energy). This behavior is due to its high band gap value of 3.2 eV. The modification of light harvesting properties of TiO2 by doping has become an important research topic to achieve an efficient operating range under UV and visible light. In addition, the structure and surface properties …
