    A Mobile Laboratory/Propagation Measurement Van (PMV) was developed to support the field experiments of the Mobile Satellite Experiment (MSAT-X) Project. This van was designed to provide flexibility, self-sufficiency and data acquisition to allow for both measurement of equipment performance and the mobile environment. The design philosophy and implementation of the PMV are described. The Pilot Field Experiments and an overall description of the three experiments in which the PMV was used are described

    Testing the Hypothesis of Contagion using Multivariate Volatility Models

    The aim of this paper is to test whether or not there was evidence of contagion across the various financial crises that assailed some countries in the 1990s. Data on sovereign debt bonds for Brazil, Mexico, Russia and Argentina were used to implement the test. The contagion hypothesis is tested using multivariate volatility models. If there is any evidence of structural break in volatility that can be linked to financial crises, the contagion hypothesis will be confirmed. Results suggest that there is evidence in favor of the contagion hypothesisContagion, Multivariate Volatility Models

    My subject this morning is \u27The Principles of War,\u27 and I\u27d like to begin by categorizing war as a science and as an art. Let us define science as a body of systematized knowledge, and art as skill in the application of knowledge to the accomplishment of a concrete purpose

    Epic Nonsense: The Genesis of Me Prometheus

    Get PDF
    Me Prometheus is a musical comedy about the intersection of creativity and progress. It explores how humans react to crises, seen through the prism of the hunter-gatherer Gurg tribe. The show contains commentary on: the society of the spectacle, through the narcissistic antagonist Birns; religion, through the tribe’s drug-addled shaman; technology, through the prehistoric culture of innovation; and climate change, with the ominous advance of the glaciers. The hero’s ultimate choice of whether to save the tribe or spite them drives home the themes of the importance of community and forgiveness, two crucial elements of human society. This thesis outlines the genesis of Me Prometheus, and delves into the specific musical inspirations for the work

    Will Due Process Be Returned to Academic Suspension?: An Analysis of Academia\u27s Rejection of the Title IX Final Rule

    In 2011, the Department of Education ( DOE ) under the Obama administration issued its Dear College Letter ( DCL ) ordering publicly funded educational institutions to undertake aggressive actions to deter what was deemed an epidemic of sexual violence on college campuses. DOE subsequently aggressively enforced the directives of the DCL with scores of costly investigations of college disciplinary systems and threatened withdrawal of federal funding for institutions that failed to respond to sexual harassment claims aggressively. Hundreds of lawsuits followed in the wake of the DCL\u27s issuance. Specifically, the flood of litigation was initiated by males contending they were briskly expelled, suspended, or otherwise disciplined upon collegiate tribunals\u27 findings of guilt on claims of sexual harassment. The lawsuits portrayed collegiate systems that readily found accused males responsible on claims of sexual harassment through denial of fundamental due process rights and predetermined conclusions that equated the claim of sexual harassment with guilt on the charge. The majority of these lawsuits resulted in recognizing the deprivation of rights for the accused males in the universities\u27 rush to judgment on sexual harassment claims. In May 2020, the DOE, under the Trump administration, released its Title IX Final Rule comprehensively addressing all aspects of publicly funded educational institutions\u27 obligations in responding to claims of sexual harassment. The Final Rule\u27s eighty-two sections created a procedural framework for adjudicating Title IX sexual harassment claims based solely on the determination of the factual validity of the complainant\u27s allegations. Academia has unceasingly opposed the Final Rule from its original November 2017 publication for public comment. Repeatedly, the charge is made that the Final Rule will inevitably unleash a pandemic of sexual violence against collegiate women. Joseph Biden campaigned for the presidency with a commitment that the Final Rule would be swiftly and surely rescinded. Accordingly, President Biden issued an executive order in March 2021 as the administration\u27s first step in eradicating the Final Rule. However, the Final Rule has proved to be a law immune to swift elimination. A series of lawsuits seeking to overturn the Final Rule failed. Moreover, the Biden administration\u27s actions have acknowledged that the Final Rule can only be rescinded and replaced through compliance with the Administrative Procedures Act and its public comment requirement. DOE has indicated a proposed replacement or drastic revision of the Final Rule will be published for public comment in April 2022. Thus, the Final Rule will likely remain an enforceable law throughout 2022. The public comment period will inevitably be contention as the Final Rule is one of the many issues on which America is deeply divided. This article undertakes a history from the 1972 enactment of Title IX through the present setting forth the administrative, legislative, and judicial events that have led to the nation\u27s deep division over the role of government in pronouncing and enforcing permissive sexual practices on college campuses. It concludes with considering the motivations underlying academia\u27s consistent hostility to the Final Rule

    Testing the long-run implications of the expectation hypothesis using cointegration techniques with structural change

    This paper investigates whether or not multivariate cointegrated process with structural change can describe the Brazilian term structure of interest rate data from 1995 to 2006. In this work the break point and the number of cointegrated vector are assumed to be known. The estimated model has four regimes. Only three of them are statistically different. The first starts at the beginning of the sample and goes until September of 1997. The second starts at October of 1997 until December of 1998. The third starts at January of 1999 and goes until the end of the sample. It is used monthly data. Models that allows for some similarities across the regimes are also estimated and tested. The models are estimated using the Generalized Reduced-Rank Regressions developed by Hansen (2003). All imposed restrictions can be tested using likelihood ratio test with standard asymptotic qui-squared distribution. The results of the paper show evidence in favor of the long run implications of the expectation hypothesis for Brazil.Term structure, cointegration, structural change
