Struggling to Remember: Perceptions, Potentials and Power in an Age of Mediatised Memory

What role do new, networked and pervasive technologies play in changing individual and collective memory processes? Many recent debates have focused on whether we are in the online era remembering ‘less’ or ‘more’ – informed, perhaps, by a tendency to think of memory spatially and quantifiably as working like an archive. Drawing on the philosophical theorising of Henri Bergson and its development through Gilbert Simondon, this thesis makes two interventions into the field. Firstly, conceptually, it establishes a process-based approach to perception, memory and consciousness in a shift away from the archive metaphor – thinking memory not as informing ‘knowledge of the past’ but ‘action in duration’. It situates the conscious, living being as transindividual – affectively relational to its perceived bodily and social environments, through psychic and collective individuation respectively. Moreover, it considers technologies as forms of transindividual extension of consciousness. Furthermore, it proposes the ‘antimetaphor’ of the anarchive as a conceptual tool with which to understand these durationbased, bodily and technological, action-oriented processes. Secondly, methodologically, it advocates a rephrasing of the question from how much we are remembering to how we are remembering differently. Armed now with a developed theoretical position and methodological approach, the thesis explores through three case-study chapters how personal and more historical pasts may be remembered, individually and more collectively, through new, prevalent technologies of memory such as search engines, forums and social-media sites. Analysing the material experiences of remembering, as well as examining the economic drives of the platforms and wider actors, and the resulting socio-political implications, the thesis sets out the original argument of a contemporary struggle for memory: a complex negotiation of tensions between agencies of the body, the social, and the multifarious and interconnected socio-political and economic interests of the technological platforms and hybridised media systems through which contemporary remembering increasingly takes place

Aerodynamic effects of a split flap on the spinning characteristics of a monoplane model

The investigation described in this report was made to determine the change in aerodynamic forces and moments produced by split flaps in a steady spin. The test were made with the spinning balance in the NACA 5-foot vertical wind tunnel. A low-wing monoplane model was tested with and without the split flaps in 12 spinning attitudes chosen to cover the probable spinning range. The changes in coefficients produced by adding the split flaps are given for longitudinal force, normal force, and rolling and yawing moments about body axes. The results obtained indicate that the use of split flaps on an airplane is unlikely, in any case, to have much beneficial effect on a spin, and it might make the spin dangerous. The change in the spin will depend upon the aerodynamic and inertia characteristics of the particular airplane. A dangerous condition is most likely to be attained with airplanes which are statically stable in yaw in the spinning attitude and which have large weights distributed along wings

Wind tunnel tests on airfoil boundary control using a backward opening slot

This report presents the results of an investigation to determine the effect of boundary layer control on the lift and drag of an airfoil equipped with a backward opening slot. Various slot locations, widths of opening, and pressures, were used. The tests were conducted in the Five-Foot Atmospheric Wind Tunnel of the Langley Memorial Aeronautical Laboratory. The greatest increase in maximum lift was 96 per cent, the greatest decrease in minimum drag was 27 per cent, and the greatest increase in the ratio, maximum lift coefficient/minimum drag coefficient, was 151 per cent

Wind Tunnel Tests on a Model of a Monoplane Wing with Floating Ailerons

This report describes preliminary wind tunnel tests on a model of a monoplane wing equipped with wing tip floating ailerons. Lift and drag, as well as rolling and yawing moments, were measured

The Aerodynamic Forces and Moments on a Spinning Model of the F4B-2 Airplane as Measured by the Spinning Balance

The aerodynamic forces and moments on a 1/12-scale model of the F4B-2 airplane were measured with the spinning balance in nine spinning attitudes with three sets of tail surfaces, namely, F4B-2 surfaces; F4B-4 fin and rudder with rectangular stabilizer; and with all tail surfaces removed. In one of these attitudes measurements were made to determine the effect upon the forces and moments of independent and of simultaneous displacement of the rudder and elevator for two of the sets of tail surfaces. Additional measurements were made for a comparison of model and full-scale data for six attitudes that were determined from flight tests with various control settings. The characteristics were found to vary in the usual manner with angle of attack and sideslip. The F4B-2 surfaces were quite ineffective as a source of yawing moments. The F4B-4 fin and F4B-2 stabilizer gave a greater damping yawing moment when controls were against the spin than did the F4B-2 surfaces but otherwise there was little difference. Substitution of a rectangular stabilizer for the F4B-2 stabilizer made no appreciable difference in the coefficient. Further comparisons with other airplane types are necessary before final conclusions can be drawn as to the relations between model and full-scale spin measurements

The impact of a seasonally ice free Arctic Ocean on the temperature, precipitation and surface mass balance of Svalbard

The observed decline in summer sea ice extent since the 1970s is predicted to continue until the Arctic Ocean is seasonally ice free during the 21st Century. This will lead to a much perturbed Arctic climate with large changes in ocean surface energy flux. Svalbard, located on the present day sea ice edge, contains many low lying ice caps and glaciers and is expected to experience rapid warming over the 21st Century. The total sea level rise if all the land ice on Svalbard were to melt completely is 0.02 m. The purpose of this study is to quantify the impact of climate change on Svalbard’s surface mass balance (SMB) and to determine, in particular, what proportion of the projected changes in precipitation and SMB are a result of changes to the Arctic sea ice cover. To investigate this a regional climate model was forced with monthly mean climatologies of sea surface temperature (SST) and sea ice concentration for the periods 1961–1990 and 2061–2090 under two emission scenarios. In a novel forcing experiment, 20th Century SSTs and 21st Century sea ice were used to force one simulation to investigate the role of sea ice forcing. This experiment results in a 3.5 m water equivalent increase in Svalbard’s SMB compared to the present day. This is because over 50 % of the projected increase in winter precipitation over Svalbard under the A1B emissions scenario is due to an increase in lower atmosphere moisture content associated with evaporation from the ice free ocean. These results indicate that increases in precipitation due to sea ice decline may act to moderate mass loss from Svalbard’s glaciers due to future Arctic warming

A Changing World of Workplace Conflict Resolution and Employee Voice: An Australian Perspective

The authors contribute to dispute resolution theory and provide new insights on such important issues as employee voice, workplace disputes and employees’ intentions to quit. They conducted and analyzed a survey of managers in Australian workplaces. They apply Budd and Colvin’s (2008) path-finding dispute resolution framework to examine two research questions: first, is there a relationship between the resolution of disputes and employee voice as measured by employee perceptions of influence over decision-making? Second, is there a relationship between the resolution of workplace disputes and employees’ intentions to quit? These are important questions in view of the high costs of workplace conflict and employee turnover. The authors find that employee voice facilitates successful dispute resolution. Further, employee voice has the additional benefit of directly reducing employee turnover intentions, above and beyond its indirect effect by helping to resolve conflicts at work

Wind-Tunnel Tests on Airfoil Boundary Layer Control Using a Backward-Opening Slot

This report presents the results of an investigation to determine the effect of boundary layer control on the lift and drag of an airfoil. Boundary layer control was accomplished by means of a backward-opening slot in the upper surface of the hollow airfoil. Air was caused to flow through this slot by a pressure which was maintained inside the airfoil by a blower. Various slot locations, slot openings, and wing pressures were used. The tests were conducted in the 5-foot atmospheric wind tunnel of the Langley Memorial Aeronautical Laboratory. Under the test conditions, the maximum lift coefficient was increased about 96 per cent for one slot arrangement, and the minimum drag coefficient was decreased about 27 per cent for another, both being compared with the results obtained with the unslotted airfoil. It is believed from this investigation that the above effects may be increased by the use of larger slot openings, better slot locations, multiple slots, improved airfoil profiles, and trailing edge flaps

Up In The Air: How Airlines Can Improve Performance by Engaging Their Employees

[Excerpt] In the chapters that follow, we explore the competitive strategies and employment-relations strategies found in the United States (chapter 2) and in a range of other countries (chapter 3), before and after deregulation. In chapter 4 we analyze recent trends in quality, productivity, and costs, as well as employee outcomes. In chapter 5 we look more closely at selected new-entrant airlines and find a wide range of competitive and employment-relations strategies being used in this segment of the industry. In chapter 6, we examine several legacy airlines and identify the distinct strategies they have adopted to respond to competitive pressures from new-entrant airlines. These chapters each focus on selected U.S. airlines and those based in some other countries. In chapter 7, we summarize the strategies of new-entrant and legacy airlines, and offer lessons about how airlines can and do change their strategies over time in their efforts to compete more effectively. We offer recommendations, using our historical and comparative analyses to discuss whether a path forward can be identified that can provide a better balance in stakeholder outcomes. We end on a positive note, arguing that if the parties learn from their experiences and from each other, in the United States and other countries, there is a path that deals with the pressures building up in the airline industry, offering hope for a better balance between investor, employee, customer, and societal interests. Key questions are whether and from where the leadership will come to get the industry moving down this path or whether the main parties might not take such action before there is a perfect storm

Aerodynamic rolling and yawing moments produced by floating wing-tip ailerons, as measured by spinning balance

The investigation described in this report was made to determine the effectiveness of floating wing-tip ailerons as an airplane control in the spin. In these tests the ailerons, not being balanced, were set parallel to the axis of rotation, which is probably very nearly the attitude that balanced floating ailerons would assume in a spin. The tests were made with the spinning balance in the N.A.C.A. 5-foot vertical tunnel. The model was tested with and without the ailerons in 12 spinning attitudes chosen to cover the probable spinning range. Rolling- and yawing-moment coefficients are given as measured for the model with and without the ailerons, and computed values are given for the ailerons alone. The addition of floating wing-tip ailerons to the model doubled the rolling-moment coefficient and increased the yawing-moment coefficient by 0.05 and more. Both moments were in a sense to oppose the spin
