Social theory, photography and the visual aesthetic of cultural modernity

Social theory and photographic aesthetics both engage with issues of representation, realism and validity, having crossed paths in theoretical and methodological controversies. This discussion begins with reflections on the realism debate in photography, arguing that beyond the polar positions of realism and constructivism the photographic image is essentially ambivalent, reflecting the ways in which it is situated within cultural modernity. The discussion draws critically on Simmel’s sociology of the visual to elucidate these issues and compares his concept of social forms and their development with the emergence of the photograph. Several dimensions of ambivalence are elaborated with reference to the politics and aesthetics of socially engaged photography in the first half of the twentieth century. It presents a case of the autonomy of the photographic as a social form that nonetheless has the potential to point beyond reality to immanent possibilities. The discussion exemplifies the processes of aesthetic formation with reference to the ‘New Vision’ artwork of László Moholy-Nagy and the social realism of Edith Tudor Hart

Raychaudhuri equation in the self-consistent Einstein-Cartan theory with spin-density

The physical implications of the Raychaudhuri equation for a spinning fluid in a Riemann-Cartan spacetime is developed and discussed using the self-consistent Lagrangian based formulation for the Einstein-Cartan theory. It was found that the spin-squared terms contribute to expansion (inflation) at early times and may lead to a bounce in the final collapse. The relationship between the fluid's vorticity and spin angular velocity is clarified and the effect of the interaction terms between the spin angular velocity and the spin in the Raychaudhuri equation investigated. These results should prove useful for studies of systems with an intrinsic spin angular momentum in extreme astrophysical or cosmological problems

Concept For Enhancing The Tracking Of Military Unit Status & Readiness Issues, By Improving The Utility Of Unit Identification Codes (UICs) & Unit Type Codes (UTCs)

Report on study of the contents and structure of unclassified unit identification codes databases and unit type codes databases which are used by the U.S. government as a means to access and exploit the databases by non-technical and non-traditional users in a manner generally intuitive to senior enlisted members or field grade officer members of the armed forces

Advanced composite fuselage technology

Boeing's ATCAS program has completed its third year and continues to progress towards a goal to demonstrate composite fuselage technology with cost and weight advantages over aluminum. Work on this program is performed by an integrated team that includes several groups within The Boeing Company, industrial and university subcontractors, and technical support from NASA. During the course of the program, the ATCAS team has continued to perform a critical review of composite developments by recognizing advances in metal fuselage technology. Despite recent material, structural design, and manufacturing advancements for metals, polymeric matrix composite designs studied in ATCAS still project significant cost and weight advantages for future applications. A critical path to demonstrating technology readiness for composite transport fuselage structures was created to summarize ATCAS tasks for Phases A, B, and C. This includes a global schedule and list of technical issues which will be addressed throughout the course of studies. Work performed in ATCAS since the last ACT conference is also summarized. Most activities relate to crown quadrant manufacturing scaleup and performance verification. The former was highlighted by fabricating a curved, 7 ft. by 10 ft. panel, with cocured hat-stiffeners and cobonded J-frames. In building to this scale, process developments were achieved for tow-placed skins, drape formed stiffeners, braided/RTM frames, and panel cure tooling. Over 700 tests and supporting analyses have been performed for crown material and design evaluation, including structural tests that demonstrated limit load requirements for severed stiffener/skin failsafe damage conditions. Analysis of tests for tow-placed hybrid laminates with large damage indicates a tensile fracture toughness that is higher than that observed for advanced aluminum alloys. Additional recent ATCAS achievements include crown supporting technology, keel quadrant design evaluation, and sandwich process development

Interview with David McLellan July 2018

David McLellan, interviewed here, is a Fellow of Goldsmiths College, University of London and Emeritus Professor of Political Theory, University of Kent. Since the 1970s he has been one of the leading biographers, translators and commentators on Marx in the English-speaking world. He is the author of several books on Marx and Marxism, including The Young Hegelians and Karl Marx; Karl Marx: His Life and Thought; Karl Marx: Selected Writings; Marx before Marxism; and Marxism and Religion. He has also published a biography of Simone Weil, books on the political implications of Christianity, and a lengthy article on contract law and marriage. He lectures widely around the world on these topics, frequently in China, and in 2018 addressed a conference in Nairobi on religion and world peace. In this interview, or conversation, with Larry Ray and Iain Wilkinson, in July 2018, David discusses the origins of his interest in Marx, the development Marx’s thought and his critique of the Hegelians, Marx’s critical method, Marx and religion, Marx on Russia, the role of violence in social change, the relevance of Marx’s work today, and offers comments on some recent biographies. David has spent much of his intellectual career engaging with the meaning and legacy of Marxism and these reflections should generate reflection and debate on the significance of Marx and the possibilities of radical political change today

Including spin in the Raychaudhuri equation

The Raychaudhuri equation for a spin fluid matter content is developed. The equation is applied to the behavior of an irrotational, unaccelerated fluid. The development of singularities in the expansion is studied for constant spin densities.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70147/2/JMAPAQ-32-2-485-1.pd
