Bringing Stories to Life by Sharing Archival Material

Last summer I researched the experiences of women at Gettysburg College during the pivotal decade 1965-1975 with the support of a college grant, the Koble Fellowship, a ten-week humanities based faculty-mentored research project. I tracked women\u27s experiences at the college during this period and designed a digital scholarship project to share their stories. As a history major and as a feminist, a project about the history of women and their activism on campus nicely complemented by interests. (excerpt

Turning Points: Women at Gettysburg College from 1965-1975

This poster is a summary of Christina Noto’s summer research. The research focuses on the experiences of Women at Gettysburg College from the Fall of 1964 to the Spring of 1975. While women attended Gettysburg College, they faced discrimination in all aspects of college life-- in the classroom, athletics, activities, their social lives and housing. This poster focuses on the housing discrimination women faced. Women had much stricter housing regulations. For example, women had to sign in and out of their dorms. Women also had mandatory dorm hours (certain times they had to be in their rooms). While some students were frustrated with the College’s policies and some women noticed discrimination; others did not, or were not frustrated by it. As more and more women questioned the way they were treated, particularly with regards to women’s hours, they planned a sleep-in on March 15, 1969 in the Student Union Building (SUB). This event can be viewed as a turning point for women’s rights at Gettysburg College

Efektivitas Pendekatan Metakognisi Terhadap Penalaran Matematis Pada Matakuliah Geometri Transformasi

Mastery of geometry transformation is still low, have an impact on learning outcomes are not satisfactory. Some of it is also due to students not understand how to solve the problems of proof in geometry transformation, therefore, students should know the proper way of learning, ranging from planning to solve problems of proof. Therefore, students should be able to think how to think, so good mathematical reasoning ability is required. One approach to learning that students are aware of the way of thinking metacognitive approach. The population in this study was a sophomore Unswagati, selected by cluster sampling technique is one control and one experiment class. Data were obtained through tests of mathematical reasoning and observation sheet. Data processed by descriptive, comparative test sample t-test and regression analysis. The results showed that the effective learning of metacognitive approach to mathematical reasoning students, some indicators are met, namely (1) the mathematical reasoning students achieve classical completeness 73.33 are greater than KKM at 65, (2) the student\u27s activeness on metacognitive approach to learning with a positive effect on mathematical reasoning students by 39.60%, (3) average of mathematical reasoning student in a class experiments (average 73.33) is better than the control class (average 40.38)

Resistive relaxation in field-induced insulator-metal transition of a (La0.4_{0.4}Pr0.6_{0.6})1.2_{1.2}Sr1.8_{1.8}Mn2_{2}O7_{7} bilayer manganite single crystal

We have investigated the resistive relaxation of a (La$_{0.4}$Pr$_{0.6}$)$_{1.2}$Sr$_{1.8}$Mn$_{2}$O$_{7}$ single crystal, in order to examine the slow dynamics of the field-induced insulator to metal transition of bilayered manganites. The temporal profiles observed in remanent resistance follow a stretched exponential function accompanied by a slow relaxation similar to that obtained in magnetization and magnetostriction data. We demonstrate that the remanent relaxation in magnetotransport has a close relationship with magnetic relaxation that can be understood in the framework of an effective medium approximation by assuming that the first order parameter is proportional to the second order one.Comment: 6 pages,5 figure

Van der Waals and resonance interactions between accelerated atoms in vacuum and the Unruh effect

We discuss different physical effects related to the uniform acceleration of atoms in vacuum, in the framework of quantum electrodynamics. We first investigate the van der Waals/Casimir-Polder dispersion and resonance interactions between two uniformly accelerated atoms in vacuum. We show that the atomic acceleration significantly affects the van der Waals force, yielding a different scaling of the interaction with the interatomic distance and an explicit time dependence of the interaction energy. We argue how these results could allow for an indirect detection of the Unruh effect through dispersion interactions between atoms. We then consider the resonance interaction between two accelerated atoms, prepared in a correlated Bell-type state, and interacting with the electromagnetic field in the vacuum state, separating vacuum fluctuations and radiation reaction contributions, both in the free-space and in the presence of a perfectly reflecting plate. We show that nonthermal effects of acceleration manifest in the resonance interaction, yielding a change of the distance dependence of the resonance interaction energy. This suggests that the equivalence between temperature and acceleration does not apply to all radiative properties of accelerated atoms. To further explore this aspect, we evaluate the resonance interaction between two atoms in non inertial motion in the coaccelerated (Rindler) frame and show that in this case the assumption of an Unruh temperature for the field is not required for a complete equivalence of locally inertial and coaccelerated points of views.Comment: 8 pages, Proceedings of the Eighth International Workshop DICE 2016 Spacetime - Matter - Quantum Mechanic

Seismic Vulnerability of the Italian Roadway Bridge Stock

This study focuses on the seismic vulnerability evaluation of the Italian roadway bridge stock, within the framework of a Civil Protection sponsored project. A comprehensive database of existing bridges (17,000 bridges with different level of knowledge) was implemented. At the core of the study stands a procedure for automatically carrying out state-of-the-art analytical evaluation of fragility curves for two performance levels – damage and collapse – on an individual bridge basis. A webGIS was developed to handle data and results. The main outputs are maps of bridge seismic risk (from the fragilities and the hazard maps) at the national level and real-time scenario damage-probability maps (from the fragilities and the scenario shake maps). In the latter case the webGIS also performs network analysis to identify routes to be followed by rescue teams. Consistency of the fragility derivation over the entire bridge stock is regarded as a major advantage of the adopted approach

Halloysite Nanotubes: Smart Nanomaterials in Catalysis

The use of clay minerals as catalyst is renowned since ancient times. Among the different clays used for catalytic purposes, halloysite nanotubes (HNTs) represent valuable resources for industrial applications. This special tubular clay possesses high stability and biocompatibility, resistance against organic solvents, and most importantly be available in large amounts at a low cost. Therefore, HNTs can be efficiently used as catalysts themselves or supports for metal nanoparticles in several catalytic processes. This review reports a comprehensive overview of the relevant advances in the use of halloysite in catalysis, focusing the attention on the last five years

Spatial distribution of rainfall trends in Sicily (1921–2000)

The feared global climate change could have important effects on various environmental variables including rainfall in many countries around the world. Changes in precipitation regime directly affect water resources management, agriculture, hydrology and ecosystems. For this reason it is important to investigate the changes in the spatial and temporal rainfall pattern in order to improve water management strategies. In this study a non-parametric statistical method (Mann–Kendall rank correlation method) is employed in order to verify the existenceof trend in annual, seasonal and monthly rainfall and the distribution of the rainfall during the year. This test is applied to about 250 rain gauge stations in Sicily (Italy) after a series of procedures finalized to the estimation of missing records and to the verification of data consistency. In order to understand the regional pattern of precipitation in Sicily, the detected trends are spatially interpolated using spatial analysis techniques in a GIS environment. The results show the existence of a generalized negative trend for the entire region
