British intelligence and threats to national security, c.1941-1951

This dissertation studies the way that Britain's intelligence services changed priorities from the Second World War to the early Cold War. It stretches from the point when the Soviet Union entered the Second World War as Britain's ally in 1941, to the moment a decade later in 1951, when the Cold War had set in and Moscow was the bitter enemy of the west. Using recently declassified Security Service (MIS) records, it examines how Britain's intelligence services met the massive transition from World War to Cold War. It reveals a variety of subjects previously undocumented in the secondary historical literature, such as MIS's concerns after the Second World War with terrorism emanating from the Middle East. The dissertation is an attempt to rescue intelligence from historical obscurity and place it in its justified position: as a central component in the process of political decision-making in Britain. As well as offering new historical insights, it provides useful lessons for governments and intelligence agencies at the start of the twenty-first century. The dissertation shows that many of the issues facing intelligence agencies at the start of the twenty-first century were, in fact, faced by the British intelligence community half a century ago

Seafloor mapping in the Arctic: support for a potential U.S. extended continental shelf

For the United States, the greatest opportunity for an extended continental shelf under UNCLOS is in the ice-covered regions of the Arctic north of Alaska. Since 2003, CCOM/JHC has been using the icebreaker Healy equipped with a multibeam echosounder, chirp subbottom profiler, and dredges, to map and sample the region of Chukchi Borderland and Alpha-Mendeleev Ridge complex. These data have led to the discovery of several new features, have radically changed our view of the bathymetry and geologic history of the area, and may have important ramifications for the determination of the limits of a U.S. extended continental shelf under Article 76

Summary of the Manufacture, Testing and Model Validation of a Full-Scale Radiator for Fission Surface Power Applications

A full-scale radiator for a lunar fission surface power application was manufactured by Material innovations, Inc., for the NASA Glenn Research Center. The radiator was designed to reject 6 kWt with an inlet water temperature of 400 K and a water mass flow rate of 0.5 kg/s. While not flight hardware, the radiator incorporated many potential design features and manufacturing techniques for future flight hardware. The radiator was tested at NASA Glenn Research Center for heat rejection performance. The results showed that the radiator design was capable of rejecting over 6 kWt when operating at the design conditions. The actual performance of the radiator as a function of operational manifolds, inlet water temperature and facility sink temperature was compared to the predictive model developed by NASA Glenn Research Center. The results showed excellent agreement with the model with the actual average face sheet temperature being within 1% of the predicted value. The results will be used in the design and production of NASA s next generation fission power heat rejection systems. The NASA Glenn Research Center s Technology Demonstration Unit will be the first project to take advantage of the newly developed manufacturing techniques and analytical models

Borders and Barriers: Knowledge Transfer and Management Challenges when making Visa Application Decisions

As governments move to increase value, deliver efficiencies and provide transparent and consistent services, the ability to manage and transfer knowledge across the organisation is playing an increasingly important part given the volume of change currently underway. This case study looks at the operational area responsible for the processing of visa applications within Immigration NZ to understand the challenges associated with managing knowledge including barriers to knowledge transfer. Through using an online survey and semi-structured interviews, we find that three main barriers exist, namely the time available, the complexity of the system as a whole and the current systems that are available and that these barriers may change depending on an individual’s role within the organisation. A separate finding was that communication channels are misaligned between preferred and actual and are via one directional channels with little opportunity for feedback to enable better decision-making. Management can mitigate these barriers through putting in place a number of activities and initiatives, including dedicated time for knowledge transfer and aligning commination channels, including the use of feedback loops across processes and systems. Through the awareness of knowledge management activities, transfer barriers, and preferred communication channels, public sector organisations can become more effective and consistent in their decision-making, delivering a better outcome for their customers

Hatteras Transverse Canyon, Hatteras Outer Ridge and environs of the U.S. Atlantic margin: A view from multibeam bathymetry and backscatter

Previously unknown features in Hatteras Transverse Canyon and environs were recently mapped during multibeam surveys of almost the entire eastern U.S. Atlantic continental margin. The newly identified features include (1) extensive landslide scarps on the walls of Hatteras Transverse and Hatteras Canyons, (2) an area of multiple landslide deposits that block lower Hatteras Transverse Canyon, (3) a large depositional feature down-canyon from the landslide deposits that rises 100 m above the uppermost Hatteras Fan and has buried the transition from the mouth of Hatteras Transverse Canyon to uppermost Hatteras Fan, (4) a zone of cyclic steps on upper Hatteras Fan that suggests super critical turbidity currents performed a series of hydraulic jumps and formed large upstream-migrating bedforms, (5) several knickpoints in the channel thalwegs of both Hatteras Transverse Canyon and Hatteras Canyon, one 40 m high, that suggest both canyon channels are out of equilibrium and are in the process of readjusting, either to the channel blockage by the extensive landslide deposits or by a readjustments to increased sedimentation during the last eustatic lowstand, (6) a large area of outcrop on the lower margin between Pamlico and Hatteras Canyons that previously was interpreted as an area of slumps, blocky slide debris and mud waves, (7) headward erosion in the head region of Hatteras Transverse Canyonwhere it has intercepted the lowest reaches of Albemarle Canyon channel as well as headward erosion in a small side channel that has eroded into Hatteras Outer Ridge and (8) sections of bedforms on Hatteras Outer Ridge that are partially buried by sediment from Washington–Norfolk Canyon channel as well as by sediment transported from Hatteras Abyssal Plain. The newly discovered features add a new level of detail to understand the recent processes that have profoundly affected Hatteras Transverse Canyon, Hatteras Canyon and, to a lesser degree, Hatteras Outer Ridge
