Barry Jacobson Oral History Interview
No full textBarry Jacobson was a member of the 63rd Infantry Division, though he was not with the units that liberated Kaufering in April 1945. After the war, he was stationed at the military government regional office in Stuttgart, where he met several displaced persons who had been prisoners at Dachau. These people told him about their experiences in the camp. Jacobson helped two of them correspond with relatives overseas. He also obtained several photographs of Dachau from another soldier
The graded Jacobson radical of associative rings
No full textWe introduce a consistent definition for the graded Jacobson radical for group graded rings without unity. We compare the graded Jacobson radical for rings with unity and those without. We find that for group graded rings, the descriptions are equivalent
International Policy Coordination: The Long View
No full textThis paper places current efforts at international economic policy coordination in historical perspective. It argues that successful cooperation is most likely in four sets of circumstances. First, when it centers on technical issues. Second, when cooperation is institutionalized – when procedures and precedents create presumptions about the appropriate conduct of policy and reduce the transactions costs of reaching an agreement. Third, when it is concerned with preserving an existing set of policies and behaviors (when it is concerned with preserving a policy regime). Fourth, when it occurs in the context of broad comity among nations. These points are elaborated through a review of 150 years of historical experience and then used to assess the scope for cooperative responses to the current economic crisis.

The Jacobson radical of rings with nilpotent homogeneous elements
No full textA result of Bergman says that the Jacobson radical of a graded algebra is homogeneous. It is shown that while graded Jacobson radical algebras have homogeneous elements nilpotent, it is not the case that graded algebras all of whose homogeneous elements are nilpotent are Jacobson radical. To contrast this, the following result of the author is slightly extended. Let R be a graded algebra generated in the degree one. If for every n, the n x n matrix algebra over R has all homogeneous elements nilpotent, then R is Jacobson radical.</p
Formamidinium-Based Dion-Jacobson Layered Hybrid Perovskites: Structural Complexity and Optoelectronic Properties
No full textLayered hybrid perovskites have emerged as a promising alternative to stabilizing hybrid organic–inorganic perovskite materials, which are predominantly based on Ruddlesden-Popper structures. Formamidinium (FA)-based Dion-Jacobson perovskite analogs are developed that feature bifunctional organic spacers separating the hybrid perovskite slabs by introducing 1,4-phenylenedimethanammonium (PDMA) organic moieties. While these materials demonstrate competitive performances as compared to other FA-based low-dimensional perovskite solar cells, the underlying mechanisms for this behavior remain elusive. Here, the structural complexity and optoelectronic properties of materials featuring (PDMA)FAn–1PbnI3n+1 (n = 1–3) formulations are unraveled using a combination of techniques, including X-ray scattering measurements in conjunction with molecular dynamics simulations and density functional theory calculations. While theoretical calculations suggest that layered Dion-Jacobson perovskite structures are more prominent with the increasing number of inorganic layers (n), this is accompanied with an increase in formation energies that render n > 2 compositions difficult to obtain, in accordance with the experimental evidence. Moreover, the underlying intermolecular interactions and their templating effects on the Dion-Jacobson structure are elucidated, defining the optoelectronic properties. Consequently, despite the challenge to obtain phase-pure n > 1 compositions, time-resolved microwave conductivity measurements reveal high photoconductivities and long charge carrier lifetimes. This comprehensive analysis thereby reveals critical features for advancing layered hybrid perovskite optoelectronics.</p
Linda Jacobson Interview Virtual Reality Evangelist
No full textIn the interview with Linda Jacobson, a Virtual Reality (VR) artist, Jacobson discusses the current and future state of VR technology’s role in the politics of the body, social identity, self, gender, class, and race. This article discusses the fact that barriers to access exist for a more diverse set of artists across race, class, and gender to engage with VR technology and the need to evolve the development platform, so artists can implement their ideas in a low-cost way. The author discusses Jaron Lanier’s ideas about using VR to explore other identities based on a theatrical model where the computer is the performance space and the audience takes part in the creation of performance. The audience then becomes co-creator in the art and is no longer just a consumer

Painting Culture, Painting Nature : Stephen Mopope, Oscar Jacobson, and the Development of Indian Art in Oklahoma
No full textIn the late 1920s, a group of young Kiowa artists, pursuing their education at the University of Oklahoma, encountered Swedish-born art professor Oscar Brousse Jacobson (1882–1966). With Jacobson’s instruction and friendship, the Kiowa Six, as they are now known, ignited a spectacular movement in American Indian art. Jacobson, who was himself an accomplished painter, shared a lifelong bond with group member Stephen Mopope (1898–1974), a prolific Kiowa painter, dancer, and musician. Painting Culture, Painting Nature explores the joint creativity of these two visionary figures and reveals how indigenous and immigrant communities of the early twentieth century traversed cultural, social, and racial divides.Painting Culture, Painting Nature is a story of concurrences. For a specific period, immigrants such as Jacobson and disenfranchised indigenous people such as Mopope transformed Oklahoma into the center of exciting new developments in Indian art, which quickly spread to other parts of the United States and to Europe. Jacobson and Mopope came from radically different worlds, and were on unequal footing in terms of power and equality, but they both experienced, according to author Gunlög Fur, forms of diaspora or displacement. Seeking to root themselves anew in Oklahoma, the dispossessed artists fashioned new mediums of compelling and original art.Although their goals were compatible, Jacobson’s and Mopope’s subjects and styles diverged. Jacobson painted landscapes of the West, following a tradition of painting nature uninfluenced by human activity. Mopope, in contrast, strove to capture the cultural traditions of his people. The two artists shared a common nostalgia, however, for a past life that they could only re-create through their art.Whereas other books have emphasized the promotion of Indian art by Euro-Americans, this book is the first to focus on the agency of the Kiowa artists within the context of their collaboration with Jacobson. The volume is further enhanced by full-color reproductions of the artists’ works and rare historical photographs.</p
