Effect Of Climatic Warming On The Pacific Walrus, And Potential Modification Of Its Helminth Fauna [Critical Comment], Robert L. Rausch, John C, George, Harry K. Brower

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The decreasing extent of sea-ice in the arctic basin as a consequence of climatic warming is modifying the behavior and diets of pagophilic pinnipeds, including the Pacific walrus, Odobenus rosmarus divergens Illiger, the species emphasized here. Mammals such as the walrus and bearded seal, Erignathus barbatus (Erxleben), cannot remain associated with the sea-ice, and continue to feed on their usual diet of benthic invertebrates inhabiting coastal waters to a depth of approximately 100 m, when the northwestward retreating ice reaches deep waters beyond the margins of the continental shelf. With reduction of their customary substrate (ice), the walrus has become …

Willingness To Pay For A Clear Night Sky: Use Of The Contingent Valuation Method, Stephanie N. Simpson

Theses

A clear night sky is a public good, and as a public good government intervention to regulate it is justifiable. Light pollution decreases the ability to view a clear, unobstructed night sky and can have biological, human health, energy related, and scientific consequences. In order for governments to intervene more effectively, an economic analysis of light pollution with regards to costs and benefits needs to be performed. This thesis demonstrates the use of the contingent valuation method to place an economic value on light pollution. Students in the RIT community were surveyed regarding their willingness to pay for a clear …

Emphasizing The User In The Usability Study: Investigating Activity Theory And Website Navigation, Heidi Trost

Theses

The effects of organizational schemes in website design have been studied using measures of speed, number of mouse-clicks, accuracy, and user recollection of website content information. This study investigates self-reported user confidence and satisfaction of websites using two different organizational schemes. Users were randomly assigned to one of the two sites and asked to perform a series of information-retrieval tasks. Time taken to complete the tasks was recorded and participants completed a survey measuring their confidence and satisfaction using a website. No significant differences were found between the two websites in respect to user self-reported confidence and satisfaction. The results …

A New Letter Of Felix De Andreis, John E. Rybolt C.M., Ph.D.

Vincentian Studies

In his introduction to this 1817 letter of Felix De Andreis, John Rybolt notes that it is of particular significance because it is the only one De Andreis wrote while he was in Sainte Genevieve, Missouri. Rybolt writes, “In this letter his response to the difficulties he faced is typical of the perspective seen throughout his correspondence: redemptive suffering, personal humility against the backdrop of his fame and success in Rome, a reliance on divine providence for the future of his mission.” De Andreis recounts the hardships of the frontier and describes his parishioners and his ministry among them. He …

Bioluminescence Imaging For Assessment And Normalization In Transfected Cell Arrays, Angela K. Pannier, Eric A. Ariazi, Abigail D. Bellis, Zain Bengali, V. Craig Jordan, Lonnie D. Shea

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Transfected cell arrays (TCAs) represent a high-throughput technique to correlate gene expression with functional cell responses. Despite advances in TCAs, improvements are needed for the widespread application of this technology. We have developed a TCA that combines a two-plasmid system and dual-bioluminescence imaging to quantitatively normalize for variability in transfection and increase sensitivity. The two-plasmids consist of: (i) normalization plasmid present within each spot, and (ii) functional plasmid that varies between spots, responsible for the functional endpoint of the array. Bioluminescence imaging of dual-luciferase reporters (renilla, firefly luciferase) provides sensitive and quantitative detection of cellular response, with minimal post-transfection processing. …

Six Degrees Of Cass Sunstein, Tracey E. George, Paul H. Edelman

Vanderbilt Law School Faculty Publications

Degrees of separation is a concept that is intuitive and appealing in popular culture as well as academic discourse: It tells us something about the connectedness of a particular field. It also reveals paths of influence and access. Paul Erdős was the Kevin Bacon of his field - math - coauthoring with a large number of scholars from many institutions and across subfields. Moreover, his work was highly cited and important. Mathematicians talk about their Erdős number (i.e., numbers of degrees of separation) as a sign of their connection to the hub of mathematics: An Erdős number of 2 means …

Investigating A Method To Measure Sperm Transfer In Chelidonura Sandrana (Opisthobranchia: Cephalaspidea), Kate Kunigelis

Independent Study Project (ISP) Collection

This paper investigates possible methods for measuring sperm transfer in the internal fertilizing, simultaneous hermaphrodite Chelidonura sandrana (Opisthobranchia: Cephalaspidea). Comparing sperm amount transferred in copulations has significance for testing the assumption that sperm transfer is linearly correlated with copulation duration as well as providing a tool for future studies. Various methods of preparing, treating, and viewing sperm samples were attempted. Two unsuccessful pilot studies were conducted to test free sperm counts and measuring sperm pellet surface area. Future research should focus on optimizing centrifugation method for surface area measurements of sperm clusters and resuspending sperm clusters to enable sperm counting. …

A Prescription To Retire The Rhetoric Of "Principles-Based Systems" In Corporate Law, Securities Regulation, And Accounting, Lawrence A. Cunningham

Vanderbilt Law Review

This Article corrects widespread misconception about whether complex regulatory systems can be described fairly as either "rules-based" or "principles-based" (also called "standards-based'). Promiscuous use of these labels has proliferated in the years since the implosion of Enron Corp. Users show an increasing habit of celebrating systems dubbed principles-based and scorning those called rules-based. While the concepts of rules and principles (or standards) are useful to classify individual provisions, they are not scalable to the level of complex regulatory systems. The Article uses examples from corporate law, securities regulation, and accounting to illustrate this problematic phenomenon. To describe or design systems …

Mutations In The Cofilin Partner Aip1/Wdr1 Cause Autoinflammatory Disease And Macrothrombocytopenia, Benjamin T Kile, Athanasia D Panopoulos, Roslynn A Stirzaker, Douglas F Hacking, Lubna H Tahtamouni, Tracy A Willson, Lisa A Mielke, Katya J Henley, Jian-Guo Zhang, Ian P Wicks, William S Stevenson, Paquita Nurden, Stephanie S Watowich, Monica J Justice

Faculty, Staff and Student Publications

A pivotal mediator of actin dynamics is the protein cofilin, which promotes filament severing and depolymerization, facilitating the breakdown of existing filaments, and the enhancement of filament growth from newly created barbed ends. It does so in concert with actin interacting protein 1 (Aip1), which serves to accelerate cofilin's activity. While progress has been made in understanding its biochemical functions, the physiologic processes the cofilin/Aip1 complex regulates, particularly in higher organisms, are yet to be determined. We have generated an allelic series for WD40 repeat protein 1 (Wdr1), the mammalian homolog of Aip1, and report that reductions in Wdr1 function …

Downregulation Of Rap1gap Contributes To Ras Transformation, Oxana Tsygankova, Gregory V. Prendergast, Kanchan Puttaswamy, Yan Wang, Michael D. Feldman, Hongbin Wang, Marcia S. Brose, Judy L. Meinkoth

Faculty, Staff and Student Publications

Although abundant in well-differentiated rat thyroid cells, Rap1GAP expression was extinguished in a subset of human thyroid tumor-derived cell lines. Intriguingly, Rap1GAP was downregulated selectively in tumor cell lines that had acquired a mesenchymal morphology. Restoring Rap1GAP expression to these cells inhibited cell migration and invasion, effects that were correlated with the inhibition of Rap1 and Rac1 activity. The reexpression of Rap1GAP also inhibited DNA synthesis and anchorage-independent proliferation. Conversely, eliminating Rap1GAP expression in rat thyroid cells induced a transient increase in cell number. Strikingly, Rap1GAP expression was abolished by Ras transformation. The downregulation of Rap1GAP by Ras required the …

Implementing Uganda’S National Wetlands Policy: A Case Study Of Kabale District, Sophie Glass

Independent Study Project (ISP) Collection

Uganda’s “National Policy for the Conservation and Management of Wetland Resources” was launched in 1995 to promote the protection of Uganda’s wetlands in order to sustain their ecological and socioeconomic functions. Despite the formal policy, wetlands continue to be drained and converted. This report examines factors that account for the divide between the National Wetlands Policy and reality. Six weeks were spent researching the challenges associated with implementing the National Wetlands Policy. Kabale District was used as a case-study to better understand the issues that institutions and stakeholders face when trying to abide by the precepts of the policy. Rapid …

“Share The Wealth” A Critical Analysis Of Private Sector Development In Uganda’S Rural And Urban Settings, Michael Roscitt

Independent Study Project (ISP) Collection

Privatization and private sector development have been primary methods of development throughout Uganda and Africa for the last 20 years. These two valuable tools, however, have been plagued by corruption as many former State Owned Enterprises are being divested into the pockets of political cronies and influential foreigners. If State Owned Enterprises were instead divested amongst a broad section of the population, local entrepreneurs with limited capital could participate in the privatization process. If responsibly divested, private sector development would then be able to have more far reaching effects because the enterprises being helped would be owned by the people. …

Permission To Change: The Role Of Culture And Cultural Tourism In Development, Heather Houser

Independent Study Project (ISP) Collection

The Batwa are an indigenous people living throughout areas of central equatorial Africa. In Uganda, they constitute a small minority and live in parts of the West and Southwest, primarily in the districts of Bundibugyo, Kabale, Kisoro and Kanungu. This study was conducted in Kisoro District and the data deals primarily with the Batwa that live there. Many of the Batwa’s ancestral homelands were declared national parks in 1991. The Batwa were forced to leave and were given no compensation. As a result, many of them are now squatters and have been forced to beg for a living. Several organizations …

An Observational Analysis Of Psychosocial Behaviors And Caregiver Responses In The Durban Children’S Home, Sarah Young

Independent Study Project (ISP) Collection

In South Africa, many children find themselves in at risk situations arising from issues like HIV, abuse, and poverty, which highly impact their mental well being by forcing them into unlivable situations. The Durban Children’s Home, located in Glenwood, Durban, works to tackle this problem, providing facilities, meals, and care for 75 homeless, abused, terminally ill, and/or poverty stricken children. Yet in coming from situations where children no longer have support of their primary caregiver or environment, these children require quality psychosocial attention in the Home. However when basic needs of so many children must be met in an institutional …

Evaluating The Medicinal Properties Of Mandravasarotra (Cinnamosa Sida) Through Chemical And Pharmacological Screening, Henry J. Bowden Jr.

Independent Study Project (ISP) Collection

I worked for four weeks at the University of Antananarivo (Ankatso), spending two weeks each in the chemistry and pharmacology laboratories. There I ran a total of eight experiments or “screens” with an alcoholic extract of the medicinal plant Mandravasarotra. This plant is found mainly in northwestern Madagascar, and is often used to stimulate contractions for women having difficulty giving birth. The plant tested positive for three secondary metabolites: tannins, steroids and flavanoids. In the pharmacological tests, the plant exhibited anti-inflammatory properties, and high toxicity in doses exceeding 10ml/kg. Together, conjectures may be made between what is known of the …

Kaya Hip-Hop In Coastal Kenya: The Urban Poetry Of Ukoo Flani, Divinity Lashelle Barkley

In the global world of the 21st Century, music is one of the few things that has the ability to cross physical as well as cultural borders, which is why my Independent Study Project (ISP) focuses on the role of hip-hop music in the youth culture in Kenya’s largest coastal city, Mombasa. Throughout history, music has proven its artistic power; inspiring people to resist oppression, challenge inequality, and even claim salvation.

This enduring characteristic of music is central to my ISP which explores the emergence of hip-hop in Kenya as well as the evolution of Ukoo Flani, one of the …

Faith As A Means Of Healing: Traditional Medicine And The Ethiopian Orthodox Church In And Around Lalibela, Lauren Anderson

Independent Study Project (ISP) Collection

This paper examines and explores the relationship between indigenous medical traditions in Ethiopia and the healing rituals of the Ethiopian Orthodox Church. The practices still upheld by the Church today are explored in depth as is the prevalence of debtera, church educated traditional healers in Ethiopia. The relationship between traditional and modern modes of medical treatment in Ethiopia is explored as well as the legitimacy of both church healing and alternative medicine worldwide. Present research into the benefits of complementary and alternative medicine (CAM) including mind/body healing is also examined.

Distribution Of Ultraviolet-Absorbing Sunscreen Compounds Across The Body Surface Of Two Species Of Scaridae, Elizabeth Cerny-Chipman

Independent Study Project (ISP) Collection

Ultraviolet radiation has far-reaching effects in marine ecosystems, but many marine organisms have UV-absorbing compounds that protect them from sun-induced damage. The mucus of coral reef fish has been found to contain mycosporine-like amino acids that absorb UV light from 309-360 nm. Using UV spectrophotometry, we examined whether fish are able to allocate these MAA sunscreen compounds to areas of the body that receive the most UV radiation. We compared absorbance spectra of mucus from the body surface of dorsal, ventral, caudal and head areas in two species of Scaridae (Scarus schlegeli and Chlorurus sordidus) from Coral Bay, Western Australia. …

Buscando La Luz: Changes In Partería And The Loss Of Feminine Autonomy In Oaxaca, Mexico, Hannah Ewert-Krocker

Independent Study Project (ISP) Collection

Birth is one of the most fundamental moments of every human being’s life, and women have long been honored in the world’s societies as sacred and vital due to their important roles as life-givers. Because of the importance of birth in the lives and societies of human beings, birth and birthing practices can reveal many values of a culture and of the women within that culture and also demonstrate how and why those values are changing. The choices women make between traditional health care and more “modern” Western models are almost always influenced by the socio-economic and cultural conditions of …

Liberation Theology In The 21st Century: The Catholic Church, The Cpt, And Rural Movements In Southern Pará, Eleanor Sharp

Independent Study Project (ISP) Collection

This study explores the present-day manifestation of liberation theology in the south of Pará, Brazil. Liberation theology has been widely recognized as an important development in theology and Latin American history that helped spark social movements across South and Central America in the 1960s, 70s, and 80s. In the Brazilian Amazon, progressive Church workers (mainly Catholic) have been historically aligned with movements to protect and regain land rights for poor rural workers. Because these movements and organizations are the primary defenders of human rights in this part of Brazil, researching the changing role of religion in their work is important …

Desarrollo Turístico Y Sustentabilidad: Caso Villa Pehuenia Y La Comunidad Mapuche Puel, Sasha Shahidi

Independent Study Project (ISP) Collection

With limited resources and overpopulation on a global level, sustainable development is the only way that human beings will be able to survive on this earth. The problem is that the dominant model of development stresses the importance of economic profits in the short term and far too often exploits natural resources and less powerful cultural groups. This creates dangerous long-term affects as natural resources and indigenous cultures that depend on them continue to disappear with no plan, or possibility, to replace them. Sustainability seeks the least negative impacts possible on the natural environment and indigenous cultures in order to …

Marketing As Constructive Engagement, Clifford J. Shultz

School of Business: Faculty Publications and Other Works

The purpose of this essay is to provoke a more comprehensive, historically accurate, and meaningful definition of marketing. Toward that outcome, the author introduces a framework for marketing that argues for constructive engagement with a complex, conflicted, and increasingly interdependent world in which marketing can and should play an important role. The framework offers a new synthesis commensurate with ideals generally espoused in macromarketing. An illustration based on longitudinal study of Vietnam is shared, with implications for current global affairs and with new directions for meaningful marketing research and practice.
