The mutoscope is a cylindrical container ranging in size from a large, standing viewing station down to a smaller, more transportable unit. These machines hold hundreds of small cards with images printed on them attached to a circular core. This core is attached to an external crank which is turned by the viewer. The booklet turns, and the cards are held tensely bent into viewing position by a small metal piece. As the cards flip by, the rapid frame rate produces the illusion of a moving image (Rossell,Living Pictures, 96).

Time-of-flight techniques have been used to measure fast neutral CO2 products from double electron transfer reactions of CO22+ ions with 4.0–7.0 keV impact energies. Double electron transfer cross sections have been determined to be in the range of (1.1–12.5) × 10−16 cm2 for reactions of CO22+ ions with CO2, CO, N2, Ar and O2.

Electron transfer cross sections have been measured for reactions of Ar2+ ions with Ar, N2, O2, CO2, CH4 and C2H6. Time-of-flight techniques have been used to measure both fast neutral Ar0 and fast Ar+ products from single- and double-electron transfer processes involving Ar2+ ions with 4.0 to 7.0 keV impact energies. Incident Ar2+ ions have produced by controlled electron impact ionisation of argon atoms. Reactions have been examined as a function of ionising electron energy and cross sections determined for ground state Ar2+(3P) ions. Charge transfer cross sections have been determined to be in the range of 3*10-16 cm2 for the systems examined. Double-electron transfer cross sections are the same order of magnitude as those measured for the corresponding single-electron transfer reactions. The state distribution of the reactant ion beam has been estimated and electron transfer cross sections obtained for single- and double-electron transfer reactions of metastable Ar2+ions. The magnitudes of electron transfer cross sections in individual systems are similar for both ground and metastable state Ar2+ reactions.

Cross-sections have been determined for one- and two-electron transfer channels in the collisions of keV gas-phase doubly charged pyrrole ions with pyrrole molecules. Measured single and double electron transfer total cross-sections approximate 45 Å2 and 15 Å2, respectively. A combination of symmetric resonance charge exchange and multistate curve-crossing models has been invoked to describe these reactions.

Despite research gathered in the Campus Climate Report, I believe that it underrepresented the student experience of the social scene. The document primarily served as an identification tool for four major problems on campus: binge drinking, sexual assault, diversity, and disengagement in the classroom. Double Take Project also identifies similar issues however, this project uses theatrical techniques to gather the anecdotal reality of the student perspective. Double Take Project expands beyond the Campus Climate Report to inspire dialogue in a variety of student-to-student interactions and, more importantly, the project seeks action and solution plans. The social scene dominates our culture and its many issues result in concern for the safety, self-identity, and development of Bucknell students into thriving adults. Double Take Project is rooted in the belief that theatre is a palpable tool for social change. Over the course of many events, Double Take Project has utilized facets of theatre to provide opportunities to voice discontent, widen perception of normalcy on campus, and inspire confidence to act on personal beliefs. The Double Take Project uses many Applied Theatre methods to impact the social scene. For example, I conducted 36 student interviews and transformed the stories into a one-woman show, Rage Behind Curtains, which I performed at multiple venues across campus. I also used interviews to create a radio show airing one story per day. I conducted ten workshops with student groups, Fraternities and Sororities, and in the classroom utilizing Augusto Boal’s Theatre of the Oppressed (TO) techniques. I also created a “social scene confessional” where I stood outside the Elaine Langone Center with a sign that read, “Tell me a story about the social scene” from a wide variety of Bucknell students. Finally, I have assembled a Forum Theatre Company based on Augusto Boal’s method of the spect-actor, utilizing participants as both actors and spectators in the theatre piece. All of the names indicated in this paper have been altered to protect the identity of the participants. While planning events and conducting various theatrical experiences, I learned that there are a series of internal and external issues contributing to our social environment. Internally, students are conflicted with personal beliefs while battling outward social pressure. Whether they are on the outskirts or center of the social scene determines their response to this conflict. For example, I have discovered that students on the borders of the social culture respond with criticism because they feel excluded, whereas the student’s centrally involved critique the culture in private and while their persona appears to not want change. Externally, there are many structural issues that contribute to the current social climate such as without Fraternity meal plans, Cafeteria space is not sufficient to feed all of the students, exclusive party culture, and gendered housing. Through meetings with Deans and staff, I have learned there are also problems between administration and students, resulting in resentment and blame. Although addressing structural issues would instigate immediate change, in my opinion, internal student conflicts are the primary cause for the current negative social atmosphere. I believe that pressure to conform is rooted in lack of personal identity. Because students simply do not know themselves, they form strong social groups that become the definition of themselves. Without confident self-awareness, large and powerful groups coerce students to accept social norms resulting in the individual’s outward distaste for change, yet internal discomfort.
