2010 Massachusetts Recreational Boater Survey: Final Report Submitted To The Massachusetts Ocean Partnership, Dan Hellin, Jack Wiggin, Kristin Uiterwyk, Kim Starbuck, Nicholas Napoli, David Terkla, Chris Watson, Anthony Roman, Leona Roach, Tim Welch Dec 2011

2010 Massachusetts Recreational Boater Survey: Final Report Submitted To The Massachusetts Ocean Partnership, Dan Hellin, Jack Wiggin, Kristin Uiterwyk, Kim Starbuck, Nicholas Napoli, David Terkla, Chris Watson, Anthony Roman, Leona Roach, Tim Welch

David G. Terkla

The Massachusetts Ocean Management Plan (Plan) completed in 2009 recognized recreational boating as an activity with “significant actual and prospective conflicts among multiple waterway uses in Massachusetts” and included the economic value of recreational boating as a key socio-economic indicator that will be used to inform coastal management. At the time of Plan completion, statistically robust recreational boating data were identified as an important need for comprehensive ocean planning. To fill this data gap, the 2010 Massachusetts Recreational Boater Survey gathered information on boating activity in Massachusetts’ coastal and ocean waters directly from recreational boaters. Researchers sent 10,000 surveys to …


Uncertainty, Technical Change, And Policy Models, Erin Baker, Leon Clarke, Jeffrey Keisler, Ekundayo Shittu Dec 2011

Uncertainty, Technical Change, And Policy Models, Erin Baker, Leon Clarke, Jeffrey Keisler, Ekundayo Shittu

Jeffrey Keisler

Both climate change and technical change are uncertain. In this paper we show the importance of including both uncertainties when modeling for policy analysis. We then develop an approach for incorporating uncertainty of technical change into climate change policy analysis. We define and demonstrate a protocol for bottom-up expert assessments about prospects for technologies. We then describe a method for using such assessments to derive a probability distribution over future abatement curves, and to estimate random return functions for technological investment in different areas. Finally, we show how these analytic results could be used in a variety of energy-economic models …

The Allure Of The Freshman Girl: Peers, Partying, And The Sexual Assault Of First-Year College Women, Brian N. Sweeney Dec 2011

The Allure Of The Freshman Girl: Peers, Partying, And The Sexual Assault Of First-Year College Women, Brian N. Sweeney

Faculty of Sociology/Anthropology Publications

Although sexual assault has long been recognized as a problem among college students, little attention has been paid to why first-year women are the most likely to be assaulted. In this article the author drew on two studies of college students to analyze peer culture and the organization of gender and sexuality within a college party scene. Within this scene, fraternity men’s masculine identities and peer status were linked to their ability to hook up with women. However, strong sexual double standards stigmatized many sexually active women, reducing their appeal as sexual partners. In contrast, men saw first-year women were …

A Re-Examination Of The Early Pueblo I Components At Monument Village, 42sa971, Rachel K. Pollock Dec 2011

A Re-Examination Of The Early Pueblo I Components At Monument Village, 42sa971, Rachel K. Pollock

Theses and Dissertations

The Pueblo I period (A.D. 750-900) was a time of widespread change in population and settlement organization in the Northern San Juan region of the American Southwest. One major distinguishing feature of the Pueblo I period is the rapid appearance of villages in the late A.D. 700s. Monument Village in southeastern Utah was excavated by Brigham Young University in the late 1960s and early 1970s, but has never been adequately described. Monument Village has a substantial early Pueblo I occupation but the dating of various structures and the size of the overall settlement are unclear. This thesis re-examines architectural and …


Changes In New Hampshire’S Republican Party: Evolving Footprint In Presidential Politics, 1960-2008, Dante J. Scala Dec 2011

Changes In New Hampshire’S Republican Party: Evolving Footprint In Presidential Politics, 1960-2008, Dante J. Scala

Carsey School of Public Policy

This brief describes a series of dramatic changes in New Hampshire's political landscape over the past four decades. Examining presidential elections from 1960 to 2008, author Dante Scala uncovers a series of significant shifts in New Hampshire's political geography at the county level. He reports that historically Republican counties Grafton and Merrimack have both tilted Democratic consistently in recent decades and that New Hampshire has become less Republican overall. All of these changes have impacted not just general elections in New Hampshire, but the Republican presidential primary as well.

Explaining Investment Policies In Microstates: The Case Of The Fiji Islands, Sudarsan Kant Dec 2011

Explaining Investment Policies In Microstates: The Case Of The Fiji Islands, Sudarsan Kant

Dissertations

Prevailing theories have failed to take into account the development of policy and institutions in microstates that are engineered to attract investments in areas of comparative advantage as these small islands confront the challenges of globalization and instead have emphasized migration, remittances and foreign aid (MIRAB) as an explanation for the survival of microstates in the global economy. This dissertation challenges the MIRAB model as an adequate explanation of investment strategy in microstates and argues that comparative advantage is a better theory to explain policy behavior of microstates. These small economies can take advantage of their exotic locations and natural …

Promotional materials that …


Examining Implementation Processes Of Positive Behavior Support, Julia Helzer Rollins Dec 2011

Examining Implementation Processes Of Positive Behavior Support, Julia Helzer Rollins

Theses and Dissertations

This study is a summary of themes found in the meeting notes of school teams implementing school-wide Positive Behavior Support. Positive Behavior Support (PBS) is a systems change process of reorganizing a school's discipline structure to put in place a positive, teaching and reinforcing focus for the improvement of student behavior (Sugai & Horner, 2006). In recent years, education researchers have established that school-wide PBS is an effective way to deliver research- based interventions to improve student behavior (Colvin & Kameenui, 1993, Gottfredson, Gottfredson, & Hybl 1993; Taylor-Green & Kartub, 2000). This study focused on the implementation process in order …


Third-Party Forgiveness In Ambivalent And Supportive Relationships, Daniel Stephen Allen Dec 2011

Third-Party Forgiveness In Ambivalent And Supportive Relationships, Daniel Stephen Allen

Theses and Dissertations

A recent trend in the study of forgiveness is to look at forgiveness outside of traditional victim-perpetrator dyads. One way of going beyond these dyads is to look at third-party forgiveness. A recent advance in the study of relationship valence is to look at the amount of positivity and negativity in a relationship as on independent scales rather than on two ends of the same spectrum. This allows for categorization of relationships that are high in both positivity and negativity—ambivalent relationships. This study attempts to combine these two recent advances. I hypothesized that participants would have more difficulty forgiving offenders …


Model For Amorphous Aggregation Processes, Samual Stranks, Heath Ecroyd, Steve Van Sluyter, Elizabeth J. Waters, John A. Carver, Lorenz Von Smekal Dec 2011

Model For Amorphous Aggregation Processes, Samual Stranks, Heath Ecroyd, Steve Van Sluyter, Elizabeth J. Waters, John A. Carver, Lorenz Von Smekal

Heath Ecroyd

The amorphous aggregation of proteins is associated with many phenomena, ranging from the formation of protein wine haze to the development of cataract in the eye lens and the precipitation of recombinant proteins during their expression and purification. While much literature exists describing models for linear protein aggregation, such as amyloid fibril formation, there are few reports of models which address amorphous aggregation. Here, we propose a model to describe the amorphous aggregation of proteins which is also more widely applicable to other situations where a similar process occurs, such as in the formation of colloids and nanoclusters. As first …


Endogenous Redox Activity In Mouse Spermatozoa And Its Role In Regulating The Tyrosine Phosphorylation Events Associated With Sperm Capacitation, Heath W. Ecroyd, Russell C. Jones, Robert J. Aitken Dec 2011

Endogenous Redox Activity In Mouse Spermatozoa And Its Role In Regulating The Tyrosine Phosphorylation Events Associated With Sperm Capacitation, Heath W. Ecroyd, Russell C. Jones, Robert J. Aitken

Heath Ecroyd

We investigated the role of endogenous redox activity in regulating the signal transduction pathway leading to tyrosine phosphorylation in mouse spermatozoa. Endogenous redox activity was monitored using a luminol-peroxidase chemiluminescent probe. Chemiluminescence increased in spermatozoa that were actively undergoing cAMP-mediated tyrosine phosphorylation events associated with capacitation and was inhibited in a dose-dependent manner by addition of catalase or diphenylene iodonium, both of which also inhibited tyrosine phosphorylation within the cell at points downstream of cAMP. Excluding bicarbonate from the incubation medium reduced the redox activity of sperm by 80-90% and dramatically reduced tyrosine phosphorylation. This study provides the first evidence …


Role Of The Epididymis In Sperm Competition, Russell Jones, Jl Dacheux, Brett Nixon, Heath Ecroyd Dec 2011

Role Of The Epididymis In Sperm Competition, Russell Jones, Jl Dacheux, Brett Nixon, Heath Ecroyd

Heath Ecroyd

Although it is generally understood that the testes recruited kidney ducts for reproductive function during the evolution of vertebrates, little is understood of the biological significance of the adaptation. In the context of the evolution of the mammalian epididymis, this report provides evidence that a major role of the epididymis is to enhance a male's chance of achieving paternity in a competitive mating system. A unique example of sperm cooperation, in monotremes is used as evidence that the epididymis produces sperm competition proteins to form groups of 100 sperm into bundles that have a forward motility nearly thrice that of …


Carboxymethylated-K-Casein: A Convenient Tool For The Identification Of Polyphenolic Inhibitors Of Amyloid Fibril Formation, John A. Carver, Peter J. Duggan, Heath Ecroyd, Yanqin Liu, Adam G. Meyer, C E. Tranberg Dec 2011

Carboxymethylated-K-Casein: A Convenient Tool For The Identification Of Polyphenolic Inhibitors Of Amyloid Fibril Formation, John A. Carver, Peter J. Duggan, Heath Ecroyd, Yanqin Liu, Adam G. Meyer, C E. Tranberg

Heath Ecroyd

Reduced and carboxymethylated-κ-casein (RCM-κ-CN) is a milk-derived amyloidogenic protein that readily undergoes nucleation-dependent aggregation and amyloid fibril formation via a similar pathway to disease-specific amyloidogenic peptides like amyloid beta (Aβ), which is associated with Alzheimer’s disease. In this study, a series of flavonoids, many known to be inhibitors of Aβ fibril formation, were screened for their ability to inhibit RCM-κ-CN fibrilisation, and the results were compared with literature data on Aβ inhibition. Flavonoids that had a high degree of hydroxylation and molecular planarity gave good inhibition of RCM-κ-CN fibril formation. IC50 values were between 10- and 200-fold higher with RCM-κ-CN …


Tyrosine Phosphorylation Of Hsp-90 During Mammalian Sperm Capacitation, Heath Ecroyd, Russell Jones, Robert Aitken Dec 2011

Tyrosine Phosphorylation Of Hsp-90 During Mammalian Sperm Capacitation, Heath Ecroyd, Russell Jones, Robert Aitken

Heath Ecroyd

The process of sperm capacitation is correlated with activation of a signal transduction pathway leading to protein tyrosine phosphorylation. Whereas phosphotyrosine expression is an essential prerequisite for fertilization, the proteins that are phosphorylated during capacitation have not yet been identified. In the present study, we observed that a major target of this signaling pathway is the molecular chaperone protein, heat shock protein (HSP)-86, a member of the HSP-90 family of HSPs. We used cross-immunoprecipitation experiments to confirm the tyrosine phosphorylation of HSP-86, a process that is not inhibited by the ansamycin antibiotic, geldanamycin. The general significance of these findings was …


Dissociation From The Oligomeric State Is The Rate-Limiting Step In Fibril Formation By Kappa-Casein, Heath Ecroyd, Tomas Koudelka, David Thorn, Danielle Williams, Glyn Devlin, Peter Hoffmann, John Carver Dec 2011

Dissociation From The Oligomeric State Is The Rate-Limiting Step In Fibril Formation By Kappa-Casein, Heath Ecroyd, Tomas Koudelka, David Thorn, Danielle Williams, Glyn Devlin, Peter Hoffmann, John Carver

Heath Ecroyd

Amyloid fibrils are aggregated and precipitated forms of protein in which the protein exists in highly ordered, long, unbranching threadlike formations that are stable and resistant to degradation by proteases. Fibril formation is an ordered process that typically involves the unfolding of a protein to partially folded states that subsequently interact and aggregate through a nucleation-dependent mechanism. Here we report on studies investigating the molecular basis of the inherent propensity of the milk protein, kappa-casein, to form amyloid fibrils. Using reduced and carboxymethylated kappa-casein ( RCM kappa-CN), we show that fibril formation is accompanied by a characteristic increase in thioflavin …


An Epididymal Form Of Cauxin, A Carboxylesterase-Like Enzyme, Is Present And Active In Mammalian Male Reproductive Fluids, Heath W. Ecroyd, Maya Belghazi, Jl Dacheux, M Miyazaki, T Yamashita, Jl Gatti Dec 2011

An Epididymal Form Of Cauxin, A Carboxylesterase-Like Enzyme, Is Present And Active In Mammalian Male Reproductive Fluids, Heath W. Ecroyd, Maya Belghazi, Jl Dacheux, M Miyazaki, T Yamashita, Jl Gatti

Heath Ecroyd

Mass spectrometric analysis of a prion protein (PrP)-containing complex isolated from ram cauda epididymal fluid revealed a protein that showed homology to a carboxylesterase-like protein previously identified in cat urine (cauxin). Using anticauxin antibodies, immunoreactive bands were detected in corpus and cauda epididymal fluid from all mammals tested (ram, boar, mouse, and cat). In the ram, the protein was also present in seminal fluid but not found to be associated with sperm. The bands reacting with the anti-cauxin antibody coincided with those having esterase activity in a zymographic assay and its levels paralleled the esterase activity of native epididymal fluids. …


The Dissociated Form Of Kappa-Casein Is The Precursor To Its Amyloid Fibril Formation, Heath Ecroyd, David Thorn, Yanqin Liu, John Carver Dec 2011

The Dissociated Form Of Kappa-Casein Is The Precursor To Its Amyloid Fibril Formation, Heath Ecroyd, David Thorn, Yanqin Liu, John Carver

Heath Ecroyd

Bovine milk kappa-casein forms a self-associating oligomeric micelle-like species, in equilibrium with dissociated forms. In its native form, intra- and inter-molecular disulfide bonds lead to the formation of multimeric species ranging from monomers to decamers. When incubated under conditions of physiological pH and temperature, both reduced and non-reduced kappa-casein form highly structured beta-sheet amyloid fibrils. We investigated whether the precursor to kappa-casein fibril formation is a dissociated state of the protein or its oligomeric micelle-like form. We show that reduced kappa-casein is capable of forming fibrils well below its critical micelle concentration, i.e. at concentrations where only dissociated forms of …


The Effect Of Small Molecules In Modulating The Chaperone Activity Of Alpha B-Crystallin Against Ordered And Disordered Protein Aggregation, Heath Ecroyd, John Carver Dec 2011

The Effect Of Small Molecules In Modulating The Chaperone Activity Of Alpha B-Crystallin Against Ordered And Disordered Protein Aggregation, Heath Ecroyd, John Carver

Heath Ecroyd

Protein aggregation can proceed via disordered or ordered mechanisms, with the latter being associated with amyloid fibril formation, which has been linked to a number of debilitating conditions including Alzheimer's, Parkinson's and Creutzfeldt-Jakob diseases. Small heat-shock proteins (sHsps), such as alpha B-crystallin, act as chaperones to prevent protein aggregation and are thought to play a key role in the prevention of protein-misfolding diseases. In this study, we have explored the potential for small molecules such as arginine and guanidine to affect the chaperone activity of alpha B-crystallin against disordered (amorphous) and ordered (amyloid fibril) forms of protein aggregation. The effect …


The Interaction Of Unfolding Α-Lactalbumin And Malate Dehydrogenase With The Molecular Chaperone Αb-Crystallin: A Light And X-Ray Scattering Investigation, J W. Regini, Heath Ecroyd, Sarah Meehan, Kristen Bremmell, Matthew J. Clarke, Donna Lammie, Tim Wess, John A. Carver Dec 2011

The Interaction Of Unfolding Α-Lactalbumin And Malate Dehydrogenase With The Molecular Chaperone Αb-Crystallin: A Light And X-Ray Scattering Investigation, J W. Regini, Heath Ecroyd, Sarah Meehan, Kristen Bremmell, Matthew J. Clarke, Donna Lammie, Tim Wess, John A. Carver

Heath Ecroyd

Purpose: The molecular chaperone αB-crystallin is found in high concentrations in the lens and is present in all major body tissues. Its structure and the mechanism by which it protects its target protein from aggregating and precipitating are not known. Methods: Dynamic light scattering and X-ray solution scattering techniques were used to investigate structural features of the αB-crystallin oligomer when complexed with target proteins under mild stress conditions, i.e., reduction of α- lactalbumin at 37 °C and malate dehydrogenase when heated at 42 °C. In this investigation, the size, shape and particle distribution of the complexes were determined in real-time …


Analysis Of The Mechanism By Which Calcium Negatively Regulates The Tyrosine Phosphorylation Cascade Associated With Sperm Capacitation, Mark Baker, Louise Hethrington, Heath Ecroyd, Shaun Roman, Robert Aitken Dec 2011

Analysis Of The Mechanism By Which Calcium Negatively Regulates The Tyrosine Phosphorylation Cascade Associated With Sperm Capacitation, Mark Baker, Louise Hethrington, Heath Ecroyd, Shaun Roman, Robert Aitken

Heath Ecroyd

The capacitation of mammalian spermatozoa involves the activation of a cAMP-mediated signal transduction pathway that drives tyrosine phosphorylation via mechanisms that are unique to this cell type. Controversy surrounds the impact of extracellular calcium on this process, with positive and negative effects being recorded in independent publications. We clearly demonstrate that the presence of calcium in the external medium decreases tyrosine phosphorylation in both human and mouse spermatozoa. Under these conditions, a rise in intracellular pH was recorded, however, this event was not responsible for the observed changes in phosphotyrosine expression. Rather, the impact of calcium on tyrosine phosphorylation in …
