Measuring Ultrasonic Communication Between Mouse Pups and Adult Mother Mice

Measuring ultrasonic communication provides us with a way to study parental influence on animals. In this study I measured the ultrasonic communication between mouse pups and two maternal females, one of which who had given birth to the pups and the other had raised them. I found that there was no significant difference between the amount of noise expressed by pups in response to each the biological mother and foster mother test groups. Mouse pups call to maternal females regardless of genetic relatedness. Communication in mice may be a more complicated model because of their communal nature.

The Movement of the Gastrop Littorina Littorea in the Intertidal Zone during the Onset of Winter

The movement of the snail Littorina littoreaon the North Atlantic coast is poorly understood. Most research has concentrated on the vertical distribution of the snail, and suggests that it prefers the low intertidal zone where its food source is most plentiful. In the winter, this distribution is reinforced by a documented seaward migration of snails from the high intertidal zone in response to falling temperatures. From October 14, 2006 to January 22, 2007, I examined the individual movements and recovery of snails in response to the onset of winter. I proposed that falling water and air temperatures drive the majority of snail movement within the intertidal zone, and that water temperature had the greater effect. I also examined the possibility that, in addition to a seaward migration, winter weather patterns in the Gulf of Maine and their effect on the ocean may encourage the wintertime vertical distribution of snails. Finally, I examined the possibility that populations of snails in the comparatively inhospitable high intertidal zone may endure the winter if given access to proper resources.

Challenges in Radiative Transfer Modeling - W3 IRS5

By modeling the spectral energy distribution (SED) of the W3 IRS5 high-mass star formation region and matching this model to observed data, we can constrain the physical parameters of the basic system geometry and cloud mass distribution. From these parameters, we hope to add to the understanding of high-mass star formation processes. In particular, we hope to determine if the geometries associated with lowmass star formation carry over into the high-mass regime.

Literary Love Making in Nicholas Sparks Novels: Finding the Balance Between the Writer's Life and Writer's Work in Bestselling Romantic Love

For almost a decade now Nicholas Sparks has been writing love stories. Not only has he been publishing his stories, but they have received high acclaim in each of their installments. Several of his novels have been made into major motion pictures and increased his popularity quite significantly. His status as a successful romantic fiction writer is undeniable, but the question is, why? What is it about Nicholas Sparks that makes his novels so engaging, and personally, what do I need to do as an aspiring novelist to try and acquire the same literary status? Sparks’s novels reach readers at a number of different levels, thus giving them appeal no matter the intellectual intent of the reader. Theoretically, Sparks engages reader response techniques as well as formalist processes such as “habitualization” and “defamiliarization,” while also developing engaging plot lines that represent many of the experiences from his own life. His writing is not only academically redeemable, but it is also creatively stimulating; between the two, Sparks represents the thunder and lightning combination all writers strive for while trying to achieve literary success. This project also offers a creative element in which I attempt to exemplify many of the traits discussed in the analytical sections of this document, by recreating them in a creative, fictitious fashion. Themes such as: motion versus stasis, life versus death, and the ordinary versus the extraordinary all exist within the narrative structure of my short story “Trip to Fall.” Besides these thematic elements, the creative section strives to represent the balance Sparks achieves between the experiences of his own life and the fictitious world he creates. Overall, this project delves into the life of Nicholas Sparks to better understand the inspiration for his writing at the level of form as well as content, while also paying tribute to Sparks’s style through a representation of his work in my own words.

The Tastes of a Nation: M.F.K. Fisher and the Genre of Culinary Literature

This project works to situate this gastronomic revolution within a historical context, arguing at greater length that our contemporary food culture in the United States is in part the legacy of the body of food representations. Here we witness the evolution of a particular culinary sensibility that appealed to readers differently in different historical moments, as exhibited by the variety of ways that Fisher’s body of work was publicly received. By the end of the twentieth century, Fisher’s ethos reigned supreme, because Americans began to view food with less fear and anxiety as they slowly became more comfortable expressing their physical appetites and desires. By the millennium, Americans began to respect and honor the physical appetite and give more consideration to the quality and origin of the foods that they consumed. Feelings of guilt associated with the enjoyment of food began to diminish as well.

Conceptualizing Wilderness Through GIS

The word “wilderness” in America is generally identified with pristine places where humans are not among the primary influences on the land and its ecology. The American wilderness ethic creates a strict dichotomy between humans and nature. The Wilderness Preservation Act of 1964 defines wilderness as “an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain” (wilderness.net). This statutory definition of wilderness is essentially the functional embodiment of the American wilderness ethic. Wilderness can also be interpreted in ways that incorporate humans as active players in the natural world. Land which is managed for human use but is uninhabited can be considered wilderness to some degree because “man himself is a visitor who does not remain.” Wilderness, especially in the Northeast, can be visualized based on different land use characteristics. Conservation in the Northeast requires a redefinition of wilderness in order to incorporate land that has been utilized by humans.

Differences in the Effects of Social Context on Emotional Responding

This study compares the effects of social cues on emotional experiences of men and women. Literature suggests that emotional responses are influenced by the presence and expressiveness of other individuals (Hess, Banse, & Kappas, 1995; Jacobs, Manstead, & Fischer, 2001; Fridlund, 1991). We examined whether social cues influence the experience of emotions differently for men and women. Research on gender differences in self-construal (Cross & Madson, 1997) led us to expect that women’s own emotional reactions would be more sensitive to emotional cues from other individuals than men’s.

Assisted Living: The Politics of Medicaid and Medicare

In this paper I examine the structure of the current assisted living industry in order to explain how and why it is appealing and effective, as well as look at its limitations. I discuss the politics of Medicaid and Medicare, and how through these programs the federal and state governments are failing to provide adequate care for the nation’s senior population. Like the rest of our health care system, these two public health insurance systems are fragmented, and consequently, financing long-term care is complicated and insufficient. Ultimately, this paper will function as a policy report and I will propose: standardized requirements for assisted living facilities; a stricter and new way to regulate assisted living on the state level; restructured models for the public insurance programs, including Medicaid, Medicare, and the State Children’s Health Insurance Program.

Carl Maria von Weber’s Overture to Oberon: A History of Recorded Performance

My research examines the recorded performance history of the Overture to Weber’s Oberon in light of these aesthetic goals. I have charted changes in performance practice trends, including in timing, tempo fluctuation, rhythmic accuracy and ensemble, and the use of portamento. The twenty recordings studied that I surveyed span nearly seventy-five years, and include many of the 20th century’s most prominent conductors and orchestras, including groups from Communist Russia, both pre-World War II and post-World War II continental Europe, the British Isles, and the United States.8 Though by no means comprehensive, my selections encompass a diverse sampling of surviving recordings, ensuring a large enough sample size to reflect general trends in the performance of Weber’s masterpiece. My research and analysis confirms the conventional view of a move toward more accurate—but also more cautious, uniform, and inexpressive— performances. Surprisingly, however, this analysis also suggests that we are on the cusp of a new era in orchestra performance practice, one that shares many of the values of the earlier recorded performances. While maintaining today’s high standards of execution, modern performances now look to regain many of the past’s expressive qualities, doing so in sometimes surprising ways.

A Meeting of East and West: Can Eastern-Influenced Therapies be Effective in the Treatment of Stress and Mood Disorders?

Given that the human brain is plastic and that structural alterations have been seen in monks who meditate on a regular basis, the question arises of whether these two facts are actually related. Furthermore, if this is in fact the case, would it be possible to apply these findings to the public? In this paper I will present the different conditions that induce neuroplasticity as well as give an overview of meditation and the ways that it is practiced nowadays. To this end I will argue that if monks are able to alter the structure of their brains and the brain is naturally inclined to heal itself then incorporating eastern practices, such as mindfulness and imagery, into western therapies could benefit patients suffering from mood disorders and, in particular, stress.

Photochemical Production of MicromolarSuperoxideStandards in Aqueous SolutionT

Superoxide(O2-) is a reactive free radical that rapidly undergoes disproportionation to hydrogen peroxide and oxygen. This property makes preparation of superoxide standard for instrument calibration difficult. McDowell et al. (1983) showed photolysis of ketone and alcohol as a convenient method to generate superoxide through triplet and radical intermediates reacting with molecular oxygen. This study expands on this past work and investigates detailed mechanism of the reaction.

Prospects for Developing Countries

While developing countries generally shared the sentiment that they were going to suffer from the effects of climate change policy, evidence to the contrary has emerged during the short time since the Kyoto Protocol’s entry into force. Defying expectations that developing nations could only lose from climate change policy, Brazil has shown that it is actually quite possible to benefit significantly from these policies. Brazil has been proactive in developing the infrastructure to become involved in climate change negotiations, as well as using policy tools such as the CDM. Its actions have resulted in significant economic, developmental, and environmental benefits. The case of Brazil allows for some insight into how other countries with similar developmental profiles —specifically China and India—stand to benefit from climate change policy, and how these benefits will translate into policy for future climate negotiations.

Characterization of AFN1, a Gene Associated with Cereal Grain Germination

The AFN1 gene is transiently expressed in germinating oat grains. As AFN1 is not expressed in dormant oat grains during imbibition, we hypothesize that AFN1 may be involved in stimulating the germination process. Sequence analysis of an AFN1 cDNA clone indicates that the AFN1 polypeptide is similar to a previously identified abscisic acid (ABA) glucosyl transferase. This suggests that AFN1 may be acting to glucosylate ABA, thereby inactivating it. As the hormone ABA is known to inhibit germination, ABA glucosylation/inactivation could lead to germination in grains expressing AFN1. To test this hypothesis, we have constructed an expression plasmid that encodes an MBP::AFN1 (maltose binding protein) fusion protein. E. coli cells carrying the expression plasmid were found to produce the MBP::AFN1 fusion protein as a substantial fraction of total protein. We are currently in the process of purifying the MBP::AFN1 fusion protein by affinity chromatography, so that it can be assayed for ABA glucosyl transferase activity. We also wish to test the effect of AFN1 gene expression during grain imbibition on the germination behavior of the grains. To this end, we have constructed plasmids for the overexpression and RNAi-based suppression of AFN1 in transgenic plants. These plasmids have been introduced into oat cells by particle bombardment and we are in the process of regenerating transgenic plants for study.
