Design and evaluation of a cockpit display for hovering flight

A simulator evaluation of a cockpit display format for hovering flight is described. The display format is based on the position-velocity-acceleration representation (PVA) similar to that used in the Pilot Night Vision System in the Army AH-64 helicopter. By only varying the nature of the display law driving the primary indicator in the PVA format, i.e., the acceleration symbol, three candidate displays are created and evaluated. These range from a Status display in which the primary indicator provides true acceleration information to a Command display, in which the primary indicator provides flight director information. Simulation results indicate that two of the three displays offer performance and handling qualities which make them excellent candidates for future helicopter cockpit display systems

Particle field holography data reduction by Fourier transform analysis

The size distribution of a particle field hologram is obtained with a Fourier transformation of the Fraunhofer diffraction pattern of the reconstructed hologram. Off-axis absorption holograms of particle fields with known characteristics were obtained and analyzed with a commercially available instrument. The mean particle size of the reconstructed hologram was measured with an error of + or - 5 percent, while the distribution broadening was estimated within + or - 15 percent. Small sections of a pulsed laser hologram of a synthetic fuel spray were analyzed with this method thus yielding a spatially resolved size distribution. The method yields fast and accurate automated analysis of particle field holograms

ENABLING AND SUSTAINING SHARED LEADERSHIP IN AUTONOMOUS TEAMS

A proliferation of autonomous teams across industries entices researchers to examine the transformation of emergent leadership into sustainable shared leadership as an optimal condition for team effectiveness. Little, if any, in-depth research has surfaced in the literature to explain shared leadership. Therefore, the purpose of this study was to examine specific organizational dynamics most likely to enable and sustain shared leadership in autonomous teams. In this exploratory study, empirical feedback representing personal team experiences of 18 autonomous team members was collected and arranged in themes. What resulted was evidence that top-leader support, an institution-wide focus on team outcomes, face-toface communication and frequent feedback, and equity in team-member recruitment processes were perceived to be the most critical organizational dynamics shaping shared leadership in autonomous teams

Improving intelligence in a counterinsurgency or counterterrorism environment through the application of a critical thinking-based framework

The intelligence community is responsible for providing competent analysis and assessments pertaining to the many significant geo-political situations that may potentially or do effect the nation’s interests. The intelligence community has always experienced challenges living up to that charge, and while it may merely be a case of the nature of the profession, there are always lessons that can be learned and processes that may improve the analytical processes. Critical thinking is a cognitive process that may be able to provide that improvement to the analytical processes, and when an analytical framework is built by applying these cognitive skills, the analytical effort may become more focused and meaningful. This study examined an intelligence analysis framework that was built using specific cognitive critical thinking skills. It was demonstrated that intelligence analysis did improve, specifically with the novice analysts that participated, and there was demonstrated specificity in the respondents’ analyses. A panel of experts provided insight and content assurance that demonstrated the intelligence analysis and products produced were valuable for operational usage. Finally, successful historical counterinsurgencies were examined in relationship to the analytical framework that was utilized in order to understand how this analysis can lead to operational success

Unions and Industrial Relations in Papua New Guinea

When Papua New Guinea became independent in 1975, it inherited the Australian system of compulsory conciliation and arbitration from its former colonial rulers. This system with the cenrnal reality it ascribes to trade unions as the industrial representatives of workers has been under considerable anack in both Australia and New Zealand in recent years. In Papua New Guinea too its effectiveness has not gone unquestioned. This paper seeks first to provide some background to understanding the evolution of Papua New Guinea's industrial relations system and then looks in detail at some recent examples of its operation

Urbanisation impacts on storm runoff along a rural-urban gradient

Urbanisation alters the hydrological response of catchments to storm events and spatial measures of urban extent and imperviousness are routinely used in hydrological modelling and attribution of runoff response to land use changes. This study evaluates whether a measure of catchment urban extent can account for differences in runoff generation from storm events along an rural-urban gradient. We employed a high-resolution monitoring network across 8 catchments in the south of the UK - ranging from predominantly rural to heavily urbanised - over a four year period, and from this selected 336 storm events. Hydrological response was compared using volume- and scaled time-based hydrograph metrics within a statistical framework that considered the effect of antecedent soil moisture. Clear differences were found between rural and urban catchments, however above a certain threshold of urban extent runoff volume was relatively unaffected by changes and runoff response times were highly variable between catchments due to additional hydraulic controls. Results indicate a spatial measure of urbanisation can generally explain differences in the hydrological response between rural and urban catchments but is insufficient to explain differences between urban catchments along an urban gradient. Antecedent soil moisture alters the volume and timing of runoff generated in catchments with large rural areas, but was not found to affect the runoff response where developed areas are much greater. The results of this study suggest some generalised relationships between urbanisation and storm runoff are not represented in observed storm events and point to limitations in using a simplified representations of the urban environment for attribution of storm runoff in small urban catchments. The study points to the need for enhanced hydrologically relevant catchment descriptors specific to small urban catchments and more focused research on the role of urban soils and soil moisture in storm runoff generation in mixed land-use catchments

Chemical differentiation on one-plate planets: Predictions and geologic observations for Venus

Recent studies have examined the partial melting of planetary interiors on one-plate planets and the implications for the formation and evolution of basaltic crust and the complementary residual mantle layer. In contrast to the Earth, where the crust and residual layer move laterally and are returned to the interior following subduction, one-plate planets such as Venus are characterized by vertical accretion of the crust and residual layer. The residual mantle layer is depleted and compositionally buoyant, being less dense than undepleted mantle due to its reduced Fe/Mg and dense Al-bearing minerals; its melting temperature is also increased. As the crust and depleted mantle layer grow vertically during the thermal evolution of the planet, several stages develop. As a step in the investigation and testing of these theoretical treatments of crustal development on Venus, we investigate the predictions deriving from two of these stages (a stable thick crust and depleted layer, and a thick unstable depleted layer) and compare these to geologic and geophysical observations, speculating on how these might be interpreted in the context of the vertical crustal accretion models. In each case, we conclude with an outline of further tests and observations of these models

The Big Deal Is Dead! Long Live The Big Deal!

In many countries, the proclamation “The King is dead, long live the King” heralds the demise of the old monarch and the accession of a new one. This tradition ensures that the throne never remains empty while facilitating a smooth transition of power. When the “Big Deal” journal subscription model debuted in 1996, few suspected the extent to which academic libraries would come to rely upon it, or that it would become the primary channel by which academic libraries procure academic journal content. As budget cuts take their toll on libraries, the demise of the Big Deal model seems inevitable as the true value of all-inclusive packages becomes less evident. But is it? Collection analysis reveals that many titles included within these “Big Deal” packages remain unused or underutilized, significantly decreasing the overall value of serial subscription packages. SPARC’s Big Deal Cancellation Tracker shows an increasing number of libraries and consortia forgoing this model in favor of regaining local control over their collections and budgets. The Binghamton University Libraries is no exception. Recent curriculum changes and financial developments have prompted us to adopt an ongoing evaluation of our users’ information needs and proactively negotiate and cancel deals in order to better serve our constituents. This session described our fact finding, workflow modifications, and data analysis processes as well as the outcomes of our adventures in pursuing and planning for the cancellation of Big Deal agreements based on local collection development priorities and serials budget realities

The District Court and the Ongoing Pursuit of Local Justice in North Carolina

The state of North Carolina’s system of district courts is a prominent example of the success of legal reform, but also of the difficulties that reform can encounter. From the earliest days of the Lords Proprietors, Old English law played a significant role in colonial judicial administration. As North Carolina expanded, however, growing pains emerged; among the most severe were the availability of courts for small matters, the qualifications of those appointed to serve as judges, and the challenges brought on by interference in the court system by the executive and legislative branches of government. This Article tracks North Carolina’s long journey from judicial pariah to a model of effective governance, including the influence of other states, legal scholars, and public opinion. It concludes that the establishment of a dedicated system of district courts in the state fundamentally improved and continues to maintain—despite recent changes—a robust administration of justice in North Carolina
