Projections And Perceptions-Editorial Comment. The Import Of The Soviet Collapse For The Social Sciences, John Howard Wilhelm

The Geographical Bulletin

For me, as a Russian/Soviet specialist in economics, the collapse of the Soviet system offered a wonderful opportunity. It offered the opportunity to reintegrate into our civilization a peoples-ethnic Russians, Ukrainians, Belorussians, Baltic peoples, Armenians, Georgians, etc.- who prior to the great disasters of the First World War and the October Revolution of 1917 had contributed so much to European culture and intellectual life. Unfortunately, to date the opportunity has largely not been realized. It has not been realized for a number of reasons including: the terrible legacies left by Soviet rule, the failure to have really removed communists from …

Nonlinear Thomson Scattering In An Intense Tightly Focused Ultrashort Laser Pulse, Yance Sun

Theses and Dissertations

We investigate nonlinear Thomson scattering generated by intense laser pulses focused in noble gases. Electrons are ionized from low-density helium or argon early during the laser pulse and scatter light out the side of the focus. We measure fundamental, second, and third harmonic light focus over nearly the entire emission sphere. We investigate the influence of electron bunching, when individual atoms ionize multiple electrons sequentially as the laser field increases early during the laser pulse. Simulations suggest that correlation between electron positions for the ten electrons ionized from argon should distort the spatial pattern of nonlinear Thomson scattering relative to …

Developing A Digital Phenotype To Subdivide Adult Immunosuppressed Covid-19 Outcomes Within The English Primary Care Sentinel Network, Debasish Kar

Peninsula Medical School

Background: Adults classified as immunosuppressed have beendisproportionately affected by the COVID-19 pandemic. Compared to theimmunocompetent, certain patients are at increased risk of suboptimal vaccineresponse and adverse health outcomes if infected. However, there has beeninsufficient work to pinpoint where these risks concentrate within theimmunosuppressed spectrum; surveillance efforts typically treat theimmunosuppressed as a single entity, leading to wide confidence intervals. Aclinically meaningful and computerised medical record (CMR) compatiblemethod to subdivide immunosuppressed COVID-19 data is urgently needed.Methods: We conducted a rapid scoping review into COVID-19 mortality acrossUK immunosuppressed categories to assess if differential mortality risk was aviable means of subdivision. We converted the …

Reconstructing Cosmic Filaments Around Dwarf Galaxies With The Rubin Observatory, Sarah E. Draves, Charlotte Welker, Charlotte Olsen

Publications and Research

The cosmic web is the largest structure in the universe, consisting of streams of gas and dust that connect galaxies made of stars, dark matter, and more gas and dust. Denser areas of the cosmic web tend to have more massive and redder galaxies, which implies a strong connection between cosmic structure and galaxy evolution. The degree to which galaxies are influenced by the cosmic web outside of relatively dense areas, particularly in the case of small filaments near galaxies, is still an area of active study. Low mass galaxies, known as dwarf galaxies, are particularly sensitive to the environment …

Applying Positive Unlabeled Learning Techniques And Using The Kullback-Leibler Divergence To Improve Geothermal Surveying Assessments, Martín Thomas Rodriguez

Dissertations and Theses

As we face the current climate crisis, the discovery of geothermal energy resources has the potential to greatly reduce our dependence on fossil fuels worldwide. However, the development of any new energy infrastructure is expensive and depends on the willingness of energy agencies and developers to make initial investments based on calculated risk measures. One such measure, called geothermal favorability, is the likelihood that a site has conditions favorable for geothermal systems containing recoverable energy potential. Its prediction from existing geophysical datasets proves to be a nontrivial task. The prediction of geothermal favorability can be framed as a binary classification …

The Computational Eye. Deconstructing Style In Digital Art History, Paul Guhennec, Ellen Charlesworth

Artl@s Bulletin

With the aim of grounding digital methods in the art historic tradition, this paper uses the discussions around style as a springboard to ask how digital art history can extend beyond providing quantitative confirmation of known trends to enrich our current understanding of visual cultures. Drawing from the examples throughout this issue, we explore how an analysis of computational ways of seeing—or the ‘computational eye’—can expose the underlying preoccupations and priorities of our own research.

Afin de mieux ancrer les méthodes numériques dans la tradition de l’histoire de l’art, cet article se sert des discussions récentes autour du concept de …

Manufacturing National Boundaries? The Notion Of Style Between Identity Constructions And Spatial Approaches, Michela Passini

Artl@s Bulletin

Art historians have long been preoccupied by art’s geographical inscription. But it was during the interwar period that research on the geography of art really took off and was recognized as a field of study in its own right. This is evidenced by the organization of an international congress of art history (Stockholm, September 1933) specifically devoted to art geography.

What was the field covered in 1933 by artistic geography? How did it define its objects? And how an art history marked at the time by an extremely present methodological nationalism did shape geographical approaches?

In 2015, Brand et al. created a global database of paleocurrents, which contains over 1,000,000 measurements worldwide: North America, South America, Australia, Great Britain, parts of Western Europe, China, Africa are fairly well represented; Antarctica, Eastern Europe, and Asia are modestly represented and Russia is poorly represented. The contribution of this thesis is a web application that uses the GPlates’ Application Programming Interface (API) to visualize global paleocurrents through time in an interactive way based …

The Cftc, Mqd, And Climate Change, Todd Phillips, Will Dobbs-Allsopp

Notre Dame Law Review Reflection

In June 2022, the Commodity Futures Trading Commission (CFTC) issued a request for information (RFI) “to better inform its understanding and oversight of climate-related financial risk as pertinent to the derivatives markets and underlying commodities markets.” The financial regulatory agency is one of several working to address climate-related risks present within the financial system. Given its unique role in regulating derivatives and overseeing commodity markets, the CFTC is working to ensure that the private sector may effectively use those products to address its own climate-related risks. Because such risks threaten the nation’s financial stability and private-sector operations, it is imperative …

Kepler-51 is a ≲1 Gyr old Sun-like star hosting three transiting planets with radii ≈6-9 R ⊕ and orbital periods ≈45-130 days. Transit timing variations (TTVs) measured with past Kepler and Hubble Space Telescope (HST) observations have been successfully modeled by considering gravitational interactions between the three transiting planets, yielding low masses and low mean densities (≲0.1 g cm⁻³) for all three planets. However, the transit time of the outermost transiting planet Kepler-51d recently measured by the James Webb Space Telescope 10 yr after the Kepler observations is significantly discrepant from the prediction made by the three-planet TTV …

The Relative Strength Of Social Dominance Orientation, Belief In A Just World, And Colorblind Racial Attitudes In Predicting Support For Race-Based College-Admission Affirmative Action Policies, Allison Nicole Gaines

Walden Dissertations and Doctoral Studies

Students accepted into college programs are granted an opportunity to develop marketable skills they can use to their advantage in a competitive job market. However, students are not always afforded equal access to these opportunities. While some colleges and universities implemented race-based affirmative action policies to mitigate discrimination in the admissions process, resistance to these policies has impeded efforts to ensure that applicants receive an equal educational opportunity. Previous studies examined various legitimizing myths, such as the myth of meritocracy and just world beliefs. Yet, no studies have determined the relative strength of social dominance orientation, belief in a just …
