Isolated carbonate platforms and buildups of the Likas Formation provide a long record of carbonate sedimentation in the southern end of the Southwest Palawan Basin. While most carbonate platforms terminated in early Miocene and middle Miocene time in northern parts of western offshore Palawan (i.e. Northwest Palawan Basin and central South Palawan), carbonate deposition began later in the south during late middle Miocene time. Carbonate platforms of the Likas Formation developed in the Paragua sub-basin, which is interpreted to be a depozone eastward of the Palawan accretionary wedge in the structurally complex Southwest Palawan Basin. A regional 2D seismic grid and borehole data from four wells were used to analyze the growth patterns of the carbonate platforms, identify seismic facies, and reconstruct the evolution of the platforms. The carbonate platforms developed on the folded and faulted middle to premiddle Miocene siliciclastic strata. These older siliciclastic units were thrusted onto the southern end of the North Palawan microcontinental fragment, which represents a block of continental crust that drifted southward from South China during early Tertiary time. The platforms aggraded over time and backstepped to keep pace with increasing rates of relative sea level rise. Karst features are recognizable on seismic sections and indicate that the platforms were subaerially exposed at various times during their development. The platforms exhibit variable morphology from faulting and tilting. The platforms terminated in early Pliocene time, as relative sea level continued to rise, and were buried by deep-marine siliciclastic units.

While I do not dispute the pivotal role played by party leaders in setting and shifting a party position, I argue that the impetus for party shifts sometimes comes from the "bottom-up"--that is, from party members themselves. At times, the party position held by the leadership conflicts with some members' constituency interests. Faced with this conflict, backbench members use the legislative process to signal their intention to defect from the party on policy unless the leadership modifies the party's existing position. Party members' party-splitting votes under constituency pressures, however, do not always lead the party into a new brand. If one party, particularly a majority party, is divided but the other party is united over a policy issue, this issue drives a wedge within the majority party. If this wedge issue continues to split the majority party and unite the minority party, the majority party is likely to shift its policy position to solve its dilemma of party division. To test my theory of party position shifts, I explore three historical cases in which there was position change by one or both parties over immigration, national security, and trade. More specifically, these include: the switch of congressional Republicans from anti- to pro-exclusion on Chinese immigration in the post-Reconstruction period; the shift of congressional Democrats from a party of "guns" and "butter" to a party of only "butter" in the post-Vietnam War era; and Republican and Democratic flip-flopping on China and MFN in the post-Cold War period. My findings suggest that policy change in these cases is driven by the shifting preferences of members as they try to resolve tension between the party and the constituency. Sometimes party rank-and-file members are in the driver's seat in defining the parties' positions. This is as true for foreign policy as it is for domestic policy. My dissertation shows that in a representative democracy, the transition from voters' preferences to lawmakers' votes occurs through the politics of procedural voting strategies in Congress. / text

The long-term psychological effects of surviving a major disaster are poorly understood. A survey of survivors of the Piper Alpha oil platform disaster (1988) was undertaken to examine the role of factors relating to: the trauma; the survivors, and the survivors’ circumstances in relation to long-term outcome. Methods: Ten years after the disaster 78% (46/59) of the survivors were located, and, of these, 72% (33/46) agreed to be participate in a study conducted by questionnaire, diagnostic interview and semi-structured interview. In total, 61% of all survivors participated in this study. A further three individuals (7%) completed postal self-report measures. Results: High levels of physical disorder, general psychopathology and post-traumatic symptoms were reported. Twenty one percent (7/33) of the survivors who participated in the study still met the most stringent diagnostic criteria for PTSD over 10 years after the disaster; 73% met the same rule within three months of the disaster. Features such as physical injury, personal exposure to certain stressors during the trauma, survivor guilt, anger and employment difficulties were significantly correlated with long-term general and specific post-traumatic psychopathology and with social and occupational function. Features of the legal proceedings were also associated with long-term outcome. Whilst the media was experienced as intrusive, no statistically significant associations with long-term outcome were found. Treatment was generally accessible to participating survivors (97%) with non-professional help (82%) and outreach (69%; 25/36) widely used. Although many difficulties were experienced 61% of participants could identify some positive outcomes from the experience. Discussion: This study emphasises the need to consider a broad range of factors affecting outcome including the individual’s experience during a traumatic event, pre-existing stressors and factors relating to the response to the disaster and their environment. High rates of help-seeking were found to co-exist with high symptoms levels and this may relate to treatment effectiveness or failure to apply appropriate treatment in disaster populations. Attention to issues such as employment difficulties and compensation processes may improve survivor well-being in the long-term after disasters. Conclusions: This long-term follow-up of survivors of a major disaster has confirmed that the impact of a disaster is durable and extensive with psychological services required over prolonged periods.

The emergence of digital technology represents a paradigmatic historical shift. As a process transforming sociotechnical structures, digitalization has had pervasive effects on organizing structures and business logics, as well as contemporary society as a whole. In recent years, these effects have been particularly salient in the content-based (e.g. music and imaging), and most recently the print-media (e.g. newspapers and magazines) industries. Facing dramatically declining sales of print media products, publishers have sought to leverage digital technology for innovation. However, the digital revenues still do not yet typically compensate for the decline in print media sales. This thesis explores the organizational implications of digitalization in the media domain. Scholars have increasingly stressed that digital technology has some distinct characteristics that have fundamental implications for innovation. This thesis examines aspects of these implications that have been far from fully explored, including the roles of digital technologies as enablers of process innovation (new methods, procedures or responsibilities), product innovation outcomes (which shift or expand an organization's domain) and associated changes in organizational cognition and identity. The thesis is based on four empirical investigations, reported in appended papers, of the evolution of digital platforms, the new content creation practices they enable, and how traditional print media firms have sought to innovate and reorient themselves in relation to these novel phenomena. The composite analysis illustrates how the distinct characteristics of digital technologies are complicit in transitions from stable to fragile product categories, highlights the need for a dynamic approach to identity orientation, and discusses and proposes key concerns in scholarly studies of digital innovation in organizations based on insights generated by the underlying studies.

The increasingly diverse nature of modern applications makes it critical for future systems to have dynamic resource scaling capabilities which enable them to adapt their resource usage to meet user requirements. Such mechanisms should be both fine-grained in nature for resource-efficient operation and also provide a high scaling range to support a variety of applications with diverse needs. To this end, heterogeneous platforms, consisting of components with varying characteristics, have been proposed to provide improved performance/efficiency than homogeneous configurations, by making it possible to execute applications on the most suitable component. However, introduction of such heterogeneous architectural components requires system software to embrace complexity associated with heterogeneity for managing them efficiently. Diversity across vendors and rapidly changing hardware make it difficult to incorporate heterogeneity-aware resource management mechanisms into mainstream systems, affecting the widespread adoption of these platforms. Addressing these issues, this dissertation presents novel abstractions and mechanisms for heterogeneous platforms which decouple heterogeneity from management operations by masking the differences due to heterogeneity from applications. By exporting a homogeneous interface over heterogeneous components, it proposes the scalable 'resource state' abstraction, allowing applications to express their resource requirements which then are dynamically and transparently mapped to heterogeneous resources underneath. The proposed approach is explored for both modern mobile devices where power is a key resource and for cloud computing environments where platform resource usage has monetary implications, resulting in HeteroMates and HeteroVisor solutions. In addition, it also highlights the need for hardware and system software to consider multiple resources together to obtain desirable gains from such scaling mechanisms. The solutions presented in this dissertation open ways for utilizing future heterogeneous platforms to provide on-demand performance, as well as resource-efficient operation, without disrupting the existing software stack.

Research on the organization of systems industries generally takes the boundaries of platforms to be exogenously-determined artifacts, given by the nature of technology. This paper studies whether platform boundaries are responsive to economic incentives by studying variation in platform boundaries in competing systems in mobile computing. Using detailed descriptive evidence and systematically collected databases of integration patterns, I find that platform boundaries in this industry could be understood as established in response to three primary goals: 1) to consolidate control around assets that conferred the power to regulate production in the system as a whole; 2) to integrate economic activities that risked coordination problems; 3) to open platform boundaries in response to interactions with market competition.
