    Copula-based orderings of multivariate dependence

    In this paper I investigate the problem of defining a multivariate dependence ordering. First, I provide a characterization of the concordance dependence ordering between multivariate random vectors with fixed margins. Central to the characterization is a multivariate generalization of a well-known bivariate elementary dependence increasing rearrangement. Second, to order multivariate random vectors with non- fixed margins, I impose a scale invariance principle which leads to a copula-based concordance dependence ordering. Finally, a wide family of copula-based measures of dependence is characterized to which SpearmanĂ­s rank correlation coefficient belongs.copula, concordance ordering, dependence measures, dependence orderings, multivariate stochastic dominance, supermodular ordering

    ALL CULTURES MATTER: RACHEL DAVIS DUBOIS, THE INTERCULTURAL EDUCATION AND GROUP CONVERSATION METHODS

    In this research, I detail the professional life of Rachel Davis DuBois, with particular attention to her creation of the Woodbury Project and her work with the Intercultural Education Movement. Employing historical and biographical research methods, DuBois’ archival materials at the University of Minnesota aided my exploration of the educational movement that DuBois was instrumental in establishing in the 1930s and that continued into the 1950s in the United States. In particular, DuBois founded the Service Bureau of Intercultural Education, where she designed several workshops to educate teachers on the curriculum and discussion methods of Intercultural Education. The goal of the movement was to promote understanding and respect between people of different races, ethnicities, and religions. However, DuBois left the bureau in the 1940s due to disagreements over its goals. DuBois’ radical views on equality put her at odds with members of the bureau who favored a “melting pot” education approach that centered on tolerance. Upon leaving the Bureau of Intercultural Education, DuBois started a new organization called the Workshop for Cultural Democracy. DuBois used the new organization to spread her new Group Conversation Method. The Group Conversation Method used Intercultural Education methods in a wider community effort to bridge ethnic and racial divisions. DuBois taught the Group Conversation Method all around the country between the late 1940s and the 1980s. In the 1960s she led the dialogue training for Martin Luther King and the Southern Christian Leadership Conference (SCLC). DuBois’ work had a lasting legacy. By the 1980s, Intercultural Education had evolved into Multicultural Education. Her intergroup dialogue methods are still practiced today. Insights from the Intercultural Education Movement are relevant as racial, ethnic, and religious tensions are widespread in modern American society

    Report from the MPP Working Group to the NASA Associate Administrator for Space Science and Applications

    NASA's Office of Space Science and Applications (OSSA) gave a select group of scientists the opportunity to test and implement their computational algorithms on the Massively Parallel Processor (MPP) located at Goddard Space Flight Center, beginning in late 1985. One year later, the Working Group presented its report, which addressed the following: algorithms, programming languages, architecture, programming environments, the way theory relates, and performance measured. The findings point to a number of demonstrated computational techniques for which the MPP architecture is ideally suited. For example, besides executing much faster on the MPP than on conventional computers, systolic VLSI simulation (where distances are short), lattice simulation, neural network simulation, and image problems were found to be easier to program on the MPP's architecture than on a CYBER 205 or even a VAX. The report also makes technical recommendations covering all aspects of MPP use, and recommendations concerning the future of the MPP and machines based on similar architectures, expansion of the Working Group, and study of the role of future parallel processors for space station, EOS, and the Great Observatories era
