The Structural Finite Element Model of the C-5A

A substructured NASTRAN model of the C-5A was analyzed for several different load conditions. The size of the model and the number of load cases used presented special problems in computer file and space management. This resulted in revisions to the in-house NASTRAN code. Despite the problems encountered the analyses were completed with excellent results

“Deep Interdisciplinarity” as Critical Pedagogy: Teaching at the Intersections of Urban Communication and Public Place and Space

Interdisciplinary is a word that has been picked up by institutions of higher education, research foundations, and even popular culture as a way to articulate the need to move beyond the traditional disciplinary boundaries within which we categorize knowledge about the world. While disciplinary silos in higher education often reflect structures within which teaching and learning are engaged, we contend that critical pedagogy provides an opportunity for innovative thinking and creativity to emerge via Giroux’s (1981) critical notion of praxis. We discuss how Penny’s (2009) notion of deep interdisciplinarity can serve to guide course development in a way that enables any interdisciplinary course to achieve its inevitably unique goals. Deep interdisciplinarity, we contend, can enrich both critical and interdisciplinary pedagogies in two prominent ways: first, by expanding critical pedagogy’s focus to directly address instructor-instructor interactions as a significant in-class performance of critical reflexivity; and second, by enabling teaching and learning opportunities to reach into the places and spaces of everyday life. Using our own co-taught interdisciplinary class on urban public place and space as a provocative example, we advocate for finding opportunities to transform traditional institutional and disciplinary silos of understanding into unique learning environments situated on the “bridges” between them. Overall, we call for critical pedagogues to rethink their relationship(s) to interdisciplinary knowledge and for instructors in interdisciplinary classrooms to rethink their relationship(s) to critical pedagogy

Why Post That? Re-thinking the Problem of Absent Presence within Social Media

While social media have the potential to promote positive relations online, the increasing use of contemporary apps, such as Instagram, distances many from important face-to-face interactions. In this study, we rethink the problem of ‘absent presence’ within social media by revealing the language games of Instagram. Drawing on social media literature and Gergen’s (2002) concern about the erosion of cultural norms due to the absent presence generated by new media, we engaged in a qualitative study of active Instagram users. Employing a unique ‘prompt and response’ interview approach, in which we asked participants to explain why they would (or would not) post particular statements, we gain insights into social norms of Instagram as expressed by active social media users. The results of this study show that participants base their posting decisions largely on their perception of a desired self, without much concern for who is posting or why they are posting. Because our findings reveal that posting on Instagram is done without much engagement with others and is often done only if a message corresponds with their own experiences or self-identification, this study extends the concern about absent presence. Specifically, we argue that the complex blurring of monologic and dialogic forms of communication found in contemporary social media apps generates hollow and inconsequential language games that maintain narrow concepts of self and fail to generate interactions necessary to co-create relevant and meaningful social values

Flight control electronics reliability/maintenance study

Collection and analysis of data are reported that concern the reliability and maintenance experience of flight control system electronics currently in use on passenger carrying jet aircraft. Two airlines B-747 airplane fleets were analyzed to assess the component reliability, system functional reliability, and achieved availability of the CAT II configuration flight control system. Also assessed were the costs generated by this system in the categories of spare equipment, schedule irregularity, and line and shop maintenance. The results indicate that although there is a marked difference in the geographic location and route pattern between the airlines studied, there is a close similarity in the reliability and the maintenance costs associated with the flight control electronics
