...Michael Cabrera Structure Analyses How to Tell a True War Story In “How to Tell a True War Story,” Tim O’Brien varies from a straight forward approach because of the horrifying contents of war. Instead, his approach is one of repetition, where he retells the death of Curt Lemon, but with different versions. He adopts this structure to make it more tolerable to his audience, express that true war stories never seem to have an end, and demonstrate how truths become contradictory. True war stories by nature are so gruesome and devastating, that the author has to compromise its accuracy by inserting nonfactual, yet more palatable details to cause his listener to believe. The author supports this point when he says, “All you can do is tell it one more time, patiently, adding and subtracting, making up a few things to get to the real truth” (296). In another section he says, “Often the crazy stuff is true and the normal stuff isn’t because the normal stuff is necessary to make you believe the truly incredible craziness” (289). Interestingly, O’Brien reinforces this idea again with the example of the story that Mitchell Sanders tells. Sander says to him, “I got a confession to make… last night, man, I had to make up a few things… yeah, but listen, it’s still true…those six guys, they heard wicked sound out there…they heard sound you just plain won’t believe.” In those examples, we clearly observed how the author uses his peculiar structure to reveal the necessity...

...eventhough he continues to drink. Although these direct ties can alone prove that Poe's life is reflected in his works, more evidence is provided about his life in his stories. He thoroughly incorporates psychology into many of his stories, which he knows a great deal of. He uses personal fears in his stories, along with characteristics of his surroundings. Even though there are many a correlation more than are stated here, the connections provide here suggest that Poe's writing are an outlet and an extension for his life. Poe's mother died of consumption when he was three and Bonaparte's mother died of a pulmonary embolism when she was only two months old. This similarity was to play a role in the enthusiasm Marie Bonaparte put into her analysis of Poe's work. There is also a common theme of beautiful young women dying in Poe's works. In stories and poems of Poe, a young, innocent woman, full of life, dies in a strange and horrible way. The cause of death is generally unusual and different. There is a direct connection to Poe's life in this theme. Again, this...

...Throughout the semester of readings, and videos,I’ve learned many examples of structural racism problems affecting the food system. An example, in chapter three “From the Past to the Present”, african american farmers were considered less than white farmers. White farmers had threatened the livelihood of many african americans. African americans created other ways to help change the structure of how black farmers would be viewed, for instance the Black Panther Party. In slavery, black people had a big part in the production with harvesting products like cotton, but the system of elite white dominance brought discrimination and racism towards blacks, leaving them with little to no say in the food system. (Green, 50) Another example of structural...

...Structural Intersectionality is the idea that people with two or more minority identities have different qualitative experiences when interacting with economic arrangements, social norms, and institutions than a sum of people who hold those identities separately from one another. Crenshaw cited women’s shelters turning away women of color who did not speak English as an example of different experiences within an institution. Crenshaw shows that these structures are not only experienced differently by intersectional people, but that it also disadvantages these people while advantaging others. This happens because the structures themselves were built with a specific user base in mind, in which those with intersectional identities were not thought of. This thought process is known as essentialism, which states that there is a characteristic that...

...heavily on software to perform their design tasks. Unfortunately, most commercial structural analysis packages are closed-source, which means that the operations that the program performs cannot be inspected by the user. Moreover, such software packages are invariably very pricey, and, hence, are generally not affordable for students and smaller engineering firms. The objective of this design project was to design a structural analysis program that would be free of charge and available to all. This computer program was to be open source and well commented, so that its users could comprehend the operations performed in the analysis of a given structure. To accomplish these objectives, the generalized stiffness method of structural analysis was implemented into a computer algorithm. This algorithm, called “TrussT Structural Analysis”, is a collection of visual basic modules embedded in a Microsoft Excel document using Visual Basic for Applications (VBA). This design report outlines the theory behind TrussT Structural Analysis, as well as the methods by which that theory was implemented into computer algorithms. The first two sections of this report present the theory of the generalized stiffness method of structural analysis and its implementation into a computer algorithm. The following sections present the procedures by which the stiffness method was modified to incorporate the analysis of structure with special characteristics such as member applied loads, member...

...The structural-functional strain of sociological theory will serve as a springboard for analyzing stratification in education and employment. Stratification is a system of positions that operates as a distribute system of rewards and punishments to populations based on only on their social position rather than the people occupying them (Davis & Moore, 1945). The rewards are considered rights essential to having a given social position and punishments are considered just deserts (Davis & Moore, 1945, p. 243). As a result, inequality in institution depends on control by an elite power structure over access to institutions such as education and employment, as these power structures ensure that the most desired social positions have individuals...

...How will developing knowledge of another culture prevent from discrimination, stereotypes and structural violence? Though we may not be able to fully understand another culture, we can still learn why this group is perceived a certain way; whether that is race, sex or age. The concept Structural Violence, refers to the systematic ways in which social structures harm or otherwise disadvantaged individuals. This places stereotypes on different individuals and groups. In order to explore this problem, idea and how we might think better about it, I want to engage ideas of ethnography through art of several prominent black artists engaging the topics of structural violence. Those that are placed in poverty tend to fail on a societal scale decade...

...succeed. In class we learned about forces on simple members and then we put the members together to form a simple truss. At this point I had almost decided that structural engineering was the career for me. From there the class just took off: We went on to frames, distributed loads, considered friction; basically we were incorporating real world considerations into structural members. I loved the practical, problem solving aspects of the field. At UC my classes were even more advanced. In my analysis and design classes, I especially enjoyed studying steel design because we not only learned the use of the load resistance factor design but also applied that knowledge — I designed a four-story building. The professor was a practicing engineer, and he always related the subject to real life steel structures he had engineered, for example, the SB Medical Center, an all steel building with a base isolated campus. This is the kind of project on which I would like to work, designing the structure and considering how the building will respond to ground motion. After two quarters of structural analysis, I had come as close as possible to analyzing real world structures. Looking back I realize, I had learned great tools for structural analysis, but my "tool box" was still inadequate. I lacked a very important tool: finite element analysis....

...2551 TORSIONAL EFFECTS AND REGULARITY CONDITIONS IN RC BUILDINGS Edoardo COSENZA1, Gaetano MANFREDI2 And Roberto REALFONZO3 SUMMARY Earthquake damages at the perimeter of buildings are often the result of excessive deformations caused by torsion during the earthquake. Large torsional responses can be expected if the buildings have large eccentricity and low torsional stiffness. Modern codes, including Eurocode 8, recognise the importance of the torsional stiffness on the seismic response and include such information in its static torsional provisions. Eurocode 8 states that the static torsional provisions can be applied to torsionally unbalanced buildings with regularity in elevation that satisfies the set of conditions presented in the Annex B of the Code. Present paper shows an overview on the EC8 torsional provisions including the code background and the comparison with other codes (UBC, etc.). On the other side the EC8 provisions could be improved during the revision process. In fact recent studies on the static torsional provisions of Eurocode 8 show that the static torsional provisions generally are satisfactory in order to limit additional demands when the building has a large torsional stiffness, but the provision seems to be deficient when applied to torsional flexible models. Moreover, the behaviour of buildings designed in High Class of ductility (“HD”) is more complex. This paper compares most of the results existing in the literature, suggests proposals...
