Item Dictyostelium Myosin Bipolar Thick Filament Formation: Importance of Charge and Specific Domains of the Myosin Rod(Public Library of Science, 2004-11) Altman, David; Hostetter, Daniel; Rice, Sarah; Dean, Sara; McMahon, Peggy M.; Sutton, Shirley; Tripathy, Ashutosh; Spudich, James A.Myosin-II thick filament formation in Dictyostelium is an excellent system for investigating the phenomenon of self-assembly, as the myosin molecule itself contains all the information required to form a structure of defined size. Phosphorylation of only three threonine residues can dramatically change the assembly state of myosin-II. We show here that the C-terminal 68 kDa of the myosin-II tail (termed AD-Cterm) assembles in a regulated manner similar to full-length myosin-II and forms bipolar thick filament (BTF) structures when a green fluorescent protein (GFP) "head" is added to the N terminus. The localization of this GFP-AD-Cterm to the cleavage furrow of dividing Dictyostelium cells depends on assembly state, similar to full-length myosin-II. This tail fragment therefore represents a good model system for the regulated formation and localization of BTFs. By reducing regulated BTF assembly to a more manageable model system, we were able to explore determinants of myosin-II self-assembly. Our data support a model in which a globular head limits the size of a BTF, and the large-scale charge character of the AD-Cterm region is important for BTF formation. Truncation analysis of AD-Cterm tail fragments shows that assembly is delicately balanced, resulting in assembled myosin-II molecules that are poised to disassemble due to the phosphorylation of only three threonines.Item The Role of Freedom of Expression in a Multicultural and Democratic Society(Willamette University, 2007-03) Harmer, Peter A.; Basu, Sammy; Lathrop, Arminda; Hanson, Chris; Menely, Tobias; Binford, Warren; Kaczmarek, Joseph; McGaughey, Douglas R.; Farrin, Cassandra; Schmidt, Rich; Córdova, Nathaniel I.; Lawless, ShannonItem Time in Michael Frayn’s Copenhagen(2008-02-12T01:36:33Z) Chapman, JosephItem The Threshold of Hospitality Margrethe Bohr’s Contribution to a Lifestyle of Science and Hospitality(2008-02-12T01:41:09Z) Monroe, LauraItem The Princess and the Platformer: The Evolving Heroine in Nintendo Adventure Games(2008-02-12T16:29:05Z) Phelps, KatharineFemale characters, even as a token love interest, have been a mainstay in adventure games ever since Nintendo became a household name. One of the oldest and most famous is the princess of the Super Mario games, whose only role is to be kidnapped and rescued again and again, ad infinitum. Such a character is hardly emblematic of feminism and female empowerment. Yet much has changed in video games since the early 1980s, when Mario was born. Have female characters, too, changed fundamentally? How much has feminism and changing ideas of women in Japan and the US impacted their portrayal in console games? To address these questions, I will discuss three popular female characters in Nintendo adventure game series. By examining the changes in portrayal of these characters through time and new incarnations, I hope to find a kind of evolution of treatment of women and their gender roles.Item Science and the Staging of Copenhagen(2008-02-12T16:31:16Z) Riley, Alexandra E.Item The Conventional Housewife Takes on Quantum Physics: The Role of Margrethe in Michael Frayn’s Copenhagen(2008-02-12T16:33:12Z) Winter, HollyItem Comparative Phylogeography of a Coevolved Community: Concerted Population Expansions in Joshua Trees and Four Yucca Moths(PLOS, 2011-10-18) Smith, Christopher Irwin; Tank, Shantel; Godsoe, William; Levenick, Jim; Strand, Eva; Esque, Todd; Pellmyr, OlleItem Understanding the Need for and the Efficiency of Bridge Programs Introduction(2012-09-20) Rivas, Dina SaraiWillamette Academy (WA) is a college access program on Willamette University's campus that provides various resources to students from underrepresented communities. My research focuses on the impact this program has had on its former students' college experience. This allows an examination of the efficacy of bridge programs in providing their students tools, not only to get in college, but also to be successful in college. In order to investigate this, WA alumni who enrolled in Willamette University, Western Oregon University, and/or Chemeketa Community College were interviewed, and asked to share their experience while in the program and their experience as college students. This research is still in its preliminary stage of data analysis. But with the data gathered, I hope to compare and contrast the students' experiences by institution type to evaluate the preparation students gained from their participation at the academy; and the obstacles they faced, if any, at each of these institutions.Item Vernacular Memorials as a Response to Trauma: The Case of Missing Child Kyron Horman(2012-10-15) Collins, Catherine; Mencarelli, AnnaMariaTrauma, whether individual or collective, often triggers the impulse to commemorate. Significant scholarship assesses public memorial sites, but increasingly attention has been given to both physical and virtual vernacular memorials that construct an environment for memory preservation. In creating a place set apart from our daily routines, we gain space for the grief process. our interest is in the vernacular space, co-produced by family, friends and strangers who feel the need to have a place for mourning, for negotiating the means of their traumatic loss. one significant variant on the vernacular memorial is the use of the conventionalized form and rituals of roadside shrines to commemorate a child who is missing rather than dead. 800,000 children were reported missing in 2010. Most Cases were resolved quickly because of structural safeguards like the Amber Alert system. on June 4, 2010, Kyron Horman went missing from his school, and remains missing more than two years later, still garnering international attention through a combination of physical and virtual memorial sites. Through a case study of Kyron's physical and virtual memorials, we argue that the traumatic ambiguity of a missing child has lead to a discourse of substitution wherein the act of commemoration (co-production) replaces the traumatic ambiguity of the missing child; commemoration becomes a means, albeit imperfect, for working through both the individual trauma of loss for those who knew Kyron personally and the cultural trauma of loss that the public experiences when structural mechanisms for the protection of children fail. Kyron's memorials reflect what Foucault terms heterotopias of place and time that intensified through the use of photographs of the missing child. Whether reflecting highly personalized or more generalized cultural trauma, these physical and virtual spaces for memorialization reflect an emerging pattern of rhetorical responses to the trauma of missing children.Item Teaching Place, Ritual, and Sustainability(2013-02-06) Curry, MarshallA compilation of different documents showcasing what I learned during my experience on the farm and from my research during the summer of 2012. The place-based, hands on learning of food systems education is known to offer unique opportunities to develop student’s knowledge of sustainable agricultural practices. Through my explorative research into how classrooms work, I found that students in these programs can also develop skills as communicators, learners, leaders, and agents of change. I will present how my qualitative study of curriculum setting and its relation to the students, the farm work, and the communal elements of the Summer Institute of Sustainable Agriculture at Willamette's Zena Forest and Farm, combine to create a laboratory for self-reflection, ethics formation, and paradigm change for students. I will also discuss learning objectives and lesson plans derived from the research that could be added to any program to incorporate these outcomes that are integral to any leadership training.Item Love & Romance in 21st-Century Hollywood Superhero Films(2013-09-24) Lyman, NatalieSuperhero films and media culture constitute America’s contemporary mythology, taking elements from world cultures and mythologies to combine/remake them in fictional worlds heavily influenced by science-fiction and technological advancement. Since 2000, more than eighty Hollywood films and several TV shows focused on superheroes have appeared in the U.S. – and all of them include themes of romantic and other types of love. Yet, this topic remains almost entirely unexplored in the scholarly literature on superheroes and comics culture. Why is love so important to superheroes, and furthermore, what is “love” in the superhero universe? How realistic are these images of love, partnership, and family that today reach a massive audience and gross billions of dollars in the movie industry? This project explores the 21st-century Hollywood superhero film in terms of popular media myths about love and romance, as well as themes and qualities of love specific to the superhero genre. Issues of gender and spectatorship are also considered.
