Part I: Modified Buckling Factor For Columns In Braced And Unbraced Frames With Composite Girders, S. A. Eltawil, S. M. Abdrabou, N. S. Mahmoud

Mansoura Engineering Journal

In the current paper, the influence of composite girders on modified buckling factor values was studied in braced and unbraced frames in which the composite girders' far ends were represented as fixed and rigid. Moreover, the derived formulation is based on the modified stiffness parameter and pursues the same assumptions as in the standard effective length factor (K-factor). Furthermore, the slope-deflection method was used to obtain the modified buckling factor formulae for composite girders in braced and unbraced frames. After that, the relationship between the critical buckling factor and beam length has been demonstrated for practical purposes. In addition, the …

Resisting The Western Scientist Inside And Outside Of The Collegiate Biology Classroom, Dulce G. Ventura , '22

Senior Theses, Projects, and Awards

In this thesis, I explore how conceptions of western science and scientists invade the Swarthmore Biology department and how it impacts BIPOC students inside and outside the classroom. The findings indicate that BIPOC students are routinely harmed by many ideas conceived from colonialism. However, both students and faculty demonstrate resistance inside and outside the classroom. Inside the classroom, faculty members build strong relationships with students in small communities and negate Western science's claim of objectivity. Outside of the classroom, programs like the Biology Big Sibling-Little Sibling program are recentering BIPOC students and their lived experiences, effectively creating a community where …

The Effects Of Partisan Framing On Covid-19 Attitudes: Experimental Evidence From Early And Late Pandemic, Amber Wichowsky, Meghan Condon

Political Science Faculty Research and Publications

Political polarization has dominated news coverage of Americans’ responses to the COVID-19 pandemic. In this research note, we report findings from two experimental studies, in which we present respondents with news stories about COVID-19 mitigation measures that emphasize partisan difference or accord. The stories present the same numeric facts about public opinion, but highlight either the partisan gap that existed at the time of the study, or the fact that large majorities of both Republicans and Democrats supported the measures at the time. Results from our first study, conducted late April 2020, show that a media frame drawing attention to …

Belief Convergence Under Misspecified Learning: A Martingale Approach, Mira Frick, Ryota Iijima, Yuhta Ishii

Cowles Foundation Discussion Papers

We present an approach to analyze learning outcomes in a broad class of misspecified environments, spanning both single-agent and social learning. We introduce a novel “prediction accuracy” order over subjective models, and observe that this makes it possible to partially restore standard martingale convergence arguments that apply under correctly specified learning. Based on this, we derive general conditions to determine when beliefs in a given environment converge to some long-run belief either locally or globally (i.e., from some or all initial beliefs). We show that these conditions can be applied, first, to unify and generalize various convergence results in previously …
