In recent years, technological advancements have paved the way to acquire seismic data in innovative ways. Adopting these technologies led to increased trace densities and increased data volume. In the past, conventional acquisition with low trace densities and limited offset and azimuth distribution served well to image simple geologic targets. This led to the discovery of currently producing fields. However, exploration strategies have changed by focusing on more complex geology (e.g., unconventional reservoirs and stratigraphic traps). High density and broadband acquisition are therefore essential to map subtle and complex targets. Advancements in equipment manufacturing and survey design have made this possible.

The presence of internal multiples in seismic data can lead to artefacts in subsurface images ob-tained by conventional migration algorithms. This problem can be ameliorated by removing themultiples prior to migration, if they can be reliably estimated. Recent developments have renewedinterest in the plane wave domain formulations of the inverse scattering series (ISS) internal multipleprediction algorithms. We build on this by considering sparsity promoting plane wave transformsto minimize artefacts and in general improve the prediction output. Furthermore, we argue forthe usage of demigration procedures to enable multidimensional internal multiple prediction withmigrated images, which also facilitate compliance with the strict data completeness requirementsof the ISS algorithm. We believe that a combination of these two techniques, sparsity promotingtransforms and demigration, pave the way for a wider application to new and legacy datasets.

The French Revolution

In her keynote address to the Kristeva Circle 2014, Julia Kristeva argued that European Humanism dating from the French Revolution paradoxically paved the way for “those who use God for political ends” by promoting a completely and solely secular path to the political. As an unintended result of this movement this path has led, in the late 20th and early 21st centuries, to the development of a new form of nihilism that masks itself as revolutionary but in fact is the opposite, in Kristeva’s view.  Kristeva analyzed the culture of religious fundamentalism as “adolescent” in the sense that the adolescent, in contrast to the child, is a believer rather than a questioner.  Although the psychoanalytic consideration of religious fundamentalism added a new dimension to attempts to explain the increase of this phenomenon in the late 20th and 21st centuries, Kristeva’s subsequent linkage of fundamentalism to the revolts in French suburbs in 2005 and beyond fell short of an insightful critique by neglecting the historical context of France’s colonial history.

<p>Seismic data has been and continues to be the main tool for hydrocarbon exploration. Storing very large quantities of seismic data, as well as making it easily accessible and with machine learning functionality, is the way forward to gain regional and local understanding of petroleum systems. Seismic data has been made available as a streamed service through a web-based platform allowing seismic data access on the spot, from large datasets stored in the cloud. A data lake can be defined as transformed data used for tasks such as reporting, visualization, advanced analytics and machine learning. The global library of data has been deconstructed from the rigid flat file format traditionally associated with seismic and transformed into a distributed, scalable, big data store. This allows for rapid access, complex queries, and efficient use of computer power – fundamental criteria for enabling Big Data technologies such as deep learning.  </p><p>This data lake concept is already changing the way we access seismic data, enhancing the efficiency of gaining insights into any hydrocarbon basin. Examples include the identification of potentially prolific mixed turbidite/contourite systems in the Trujillo Basin offshore Peru, together with important implications of BSR-derived geothermal gradients, which are much higher than expected in a fore arc setting, opening new exploration opportunities. Another example is de-risking and ranking of offshore Malvinas Basin blocks by gaining new insights into areas until very recently considered to be non-prospective. Further de-risking was achieved by carrying out an in-depth source rock analysis in the Malvinas and conjugate southern South Africa Basins. Additionally, the data lake enabled the development of machine learning algorithms for channel recognition which were successfully applied to data offshore Australia and Norway.</p><p>“On demand” regional seismic dataset access is proving invaluable in our efforts to make hydrocarbon exploration more efficient and successful. Machine learning algorithms are helping to automate the more mechanical tasks, leaving time for the more valuable task of analysing the results. The geological insights gained by combining these 2 aspects confirm the value of seismic data lakes.</p>

This talk was presented as a keynote address at the Gendered Citizenship: Manifestations and Performance Conference, January 6, 2015, at the University of Warwick. In this forty-two minute audio-essay, Roy theorizes what she calls polyrhythmic citizenship, the way the intelligibility of the concept of citizenship plays out, much like music, across different contexts and cultures. She discusses “transformative constitutionalism” and “insurgent citizenship” as the component parts of this citizenship, and takes for her key examples the founding of the Indian state and its constitution, and the Delhi gang rape case of 2012 which resulted in the death of Jyoti Singh.

AbstractThis article, originally delivered as a keynote address at the 1999 Chicago World Mission Institute, points to personal and communal transformation as the key to societal change, particularly in regard to the world's refugees and displaced people. We must, in other words, "change the borders of our minds." As the article's last paragraph expresses it: As we approach the twenty-first century, we can change the way we think and act. We can change the borders of our minds and move toward creating a peace that can take root and flourish in our homes, in our communities, and throughout our world. We can effect change if we envision and believe that we do belong to one another, if we are willing to act with justice; and if we see that, in the words of the poet Archibald MacLeish, "we are brothers (and sisters), riders on the earth together."

After the riots at the 1968 Democratic National Convention, both parties altered the manner in which the party nominees were chosen. This change resulted in a shift for the conventions away from choosing the party nominee to setting the nominee and party up for the coming campaign. This study investigates the way various speeches play a role in branding the parties and their nominee. By analyzing the prime time speeches for both the Republican and Democratic Parties from 1972-2016, this study found the role each genre of address played in crafting the party brand. Notably, the analysis discovered the keynote address has three subgenres (former primary opponent, former or outgoing president, and party member representing a key constituency) with each serving a different role when utilized. Primary opponents promote party unity, former or outgoing presidents discuss their legacy to indicate the nominee is the heir to that legacy, and representatives of key constituencies attack the opposition while promoting party ideals. Spousal addresses focus on promoting a family narrative. Vice Presidential Nominees focus their branding efforts on attacking the opposition. Presidential nominees discuss a leadership narrative and policy branding. The nature of the election also impacts the party branding. An incumbent president or vice president usually has the incumbent party branding themselves as proven leaders while their opposition brand themselves as the party of change. Open elections have involved the parties battling over a qualified insider against a political outsider offering change. Finally, the Democratic Party has been less stable over the years than the Republicans in their branding. Democrats have shifted from the center to more liberal multiple times in an effort to meet the perceived desires of the American voter.

AbstractThe problem of extended fusion and identification can be approached from a diachronic perspective. Based on our own research, as well as findings from the fields of social, political, and clinical psychology, we argue that the way contemporary emotional events shape local fusion is similar to the way in which historical experiences shape extended fusion. We propose a reciprocal process in which historical events shape contemporary identities, whereas contemporary identities shape interpretations of past traumas.
