This article focuses on data gathered during the controlled destruction of a Boeing 747 airliner are helping engineers to identify ways of strengthening aircraft to make them less vulnerable to an internal explosion. Even though it may not help engineers understand the specific events in the crash of Flight 800, a controlled explosion of a Boeing 747 by the British Defence Evaluation Research Agency (DERA) , based in London, could point the way to controlling the damage from airliner explosions in the future. The 747-1 00 had been an attraction at the Bruntingthorpe Aerodrome in Leicestershire, England, before it was purchased by the British Ministry of Defence and the US Federal Aviation Administration (FAA). Initially, the meshes were too coarse for the dynamic analyses to be used in the test, so engineers refined them accordingly in the blast area. Using new features in MSC/DYTRAN 4, the team will model the airframe as a series of layers, which is representative of the lining concepts to be tested.

This paper discusses the US engagement in Afghanistan with particular reference to their withdrawal within a specified period of fourteen months. An agreement has been reached between the US and Taliban on February 29, 2020, at Doha (Qatar) followed by the intra-Afghan talks, which is expected to bring lasting peace and stability in the country. The issues of deadlock between the Afghan government and the Taliban and the pandemic COVID-19 are some of the obstacles in the way of peace. The theory of bargain provides a theoretical framework for the paper. The paper focuses on the post-withdrawal scenario of the US troops and ground realities that will help in prognosticating the future of Afghanistan. Keeping in view the post-US-Taliban agreement, it is difficult to say with certainty that peace and stability may shape the future destiny of the country since more than 1,300 casualties have happened in Afghanistan during the last three months despite the singing of the agreement.

Since its start in 1998, Software Carpentry has evolved from a week-long training course at the US national laboratories into a worldwide volunteer effort to improve researchers' computing skills. This paper explains what we have learned along the way, the challenges we now face, and our plans for the future.

The future of the Kurds in Iraq and Syria after a US withdrawal has already begun to take shape. The containment of Kurdish political and military cross-border mobility has been achieved to some extent by paving the way for Turkey’s military operations; it is now contingent on the recomposition of a desired ‘favorable balance of power” to fill the power vacuum in the Middle East. With an aggressive Turkish stance in the region, however, neither this containment policy nor the efforts made toward the maintenance of the “favorable balance of power” can be successful.

Abstract. Power facilitates goal pursuit, but how does power affect the way people respond to conflict between their multiple goals? Our results showed that higher trait power was associated with reduced experience of conflict in scenarios describing multiple goals (Study 1) and between personal goals (Study 2). Moreover, manipulated low power increased individuals’ experience of goal conflict relative to high power and a control condition (Studies 3 and 4), with the consequence that they planned to invest less into the pursuit of their goals in the future. With its focus on multiple goals and individuals’ experiences during goal pursuit rather than objective performance, the present research uses new angles to examine power effects on goal pursuit.

Abstract. This research took place just after the end of the protests following the killing of a 16-year-old boy by a policeman in Greece in December 2008. Participants (N = 224) were 16-year-olds in different schools in Attiki. Informed by the Politicized Collective Identity Model ( Simon & Klandermans, 2001 ), a questionnaire measuring grievances, adversarial attributions, emotions, vulnerability, identifications with students and activists, and questions about justice and Greek society in the future, as well as about youngsters’ participation in different actions, was completed. Four profiles of the participants emerged from a cluster analysis using representations of the conflict, emotions, and identifications with activists and students. These profiles differed on beliefs about the future of Greece, participants’ economic vulnerability, and forms of participation. Importantly, the clusters corresponded to students from schools of different socioeconomic areas. The results indicate that the way young people interpret the events and the context, their levels of identification, and the way they represent society are important factors of their political socialization that impacts on their forms of participation. Political socialization seems to be related to youngsters’ position in society which probably constitutes an important anchoring point of their interpretation of the world.

This paper attempts to rethink difference and divisibility as conditions of (im)possibility for love and survival in the wake of Derrida's newly discovered—and just recently published—Geschlecht III. I argue that Derrida's deconstruction of what he calls ‘the grand logic of philosophy’ allows us to think love and survival without positing unicity as a sine qua non. This hypothesis is tested in and through a deconstructive reading of Heidegger's second essay on Trakl in On the Way to Language, where Heidegger's phonocentrism and surreptitious nationalism converge in an effort to ‘save the earth’ from a ‘degenerate’ Geschlecht that cannot survive the internal diremption between Geschlechter. I show that one way of problematizing Heidegger's claim is to point to the blank spaces in the ‘E i n’ of Trakl's ‘E i n Geschlecht’, an internal fissuring in the very word Heidegger mobilizes in order to secure the future of mankind.

This paper explores the way American intellectuals depicted Sigmund Freud during the peak of popularity and prestige of psychoanalysis in the US, roughly the decade and a half following World War II. These intellectuals insisted upon the unassailability of Freud's mind and personality. He was depicted as unsusceptible to any external force or influence, a trait which was thought to account for Freud's admirable comportment as a scientist, colleague and human being. This post-war image of Freud was shaped in part by the Cold War anxiety that modern individuality was imperilled by totalitarian forces, which could only be resisted by the most rugged of selves. It was also shaped by the unique situation of the intellectuals themselves, who were eager to position themselves, like the Freud they imagined, as steadfastly independent and critical thinkers who would, through the very clarity of their thought, lead America to a more robust democracy.

The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.
