Love Don't Need a Reason
No full text"From a stage erected in front of the US Capitol, on April 25, 1993, Michael Callen surveyed the throng: an estimated one million people stretched across the National Mall in the largest public demonstration of queer political solidarity in history. “What a sight,” he told the crowd, his earnest Midwestern twang reverberating through loudspeakers. “You’re a sight for sore eyes. Being gay is the greatest gift I have ever been given, and I don’t care who knows about it.” He then launched into a gorgeous rendition of “Love Don’t Need a Reason,” the AIDS anthem he composed with Marsha Malamet and the late Peter Allen. As Callen finished singing, people stood cheering and flashing the familiar American Sign Language symbol for “I Love You.” For they knew the song’s sentiment rang true for Callen, who had recently announced his retirement from music and activism after a living for more than a decade with what was then called “full-blown AIDS.” After the March on Washington, Callen returned to his recently adopted West Coast home, Los Angeles. In the ensuing months, his health rapidly declined, and on 27 December 1993, Callen died of AIDS-related pulmonary Kaposi’s sarcoma.
Love Don’t Need a Reason focuses on Callen’s most important and lasting legacy: his music. A witness to the overlooked last years of Gay Liberation and a major figure in the early years of the AIDS crisis, Michael Callen chronicled these experiences in song. A community organizer, activist, author, and architect of the AIDS self-empowerment movement, he literally changed the way we have sex in an epidemic when he co-authored one of the first safe-sex guides in 1983. A gifted singer, songwriter, and performer, he also made gay music for gay people and used music to educate and empower people with AIDS. Listening again to his music allows us to hear the shifting dynamics of American families, changing notions of masculinity, gay migration to urban areas, the sexual politics of Gay Liberation, and HIV/AIDS activism. Using extensive archival materials and newly-conducted oral history interviews with Callen’s friends, family, and fellow musicians, Matthew J. Jones reintroduces Callen to the history of LGBTQIA+ music and places Callen’s music at the center of his important activist work.
Modeling the effects of aircraft flight track variability on community noise exposure
No full textThesis: S.M., Massachusetts Institute of Technology, Department of Aeronautics and Astronautics, 2017.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 119-121).The implementation of Performance Based Navigation (PBN) routes across the National Airspace System (NAS) has caused a significant concentration of flight tracks. This flight track concentration also creates a concentration of noise impacts on the communities surrounding airports, which has led to an increase in noise complaints at many airports that have implemented these routes. In order to understand these changes in noise, and to design procedures that could help mitigate any negative effects, it is important to have modeling tools capable of capturing the noise impacts of flight track variability. This thesis develops a model for this purpose. First, twenty days of radar flight trajectory data from 2015 and 2016 at Boston Logan International Airport (KBOS) is used to quantify the observed distributions of variability in speed, altitude, and lateral track position. It is shown that altitude and speed variability have relatively small impacts on noise, but that the impacts of observed lateral variability are significant. Using this information, a physics-based model is developed to capture the noise impacts of lateral flight track variability. This tool is then used to model several example scenarios. First, the changes in noise due to pre- and post-PBN procedures are examined for KBOS Runway 33L departures. Next, a hypothetical procedure is designed to intentionally introduce lateral dispersion to KBOS Runway 33L departures. Finally, the tool is used to rapidly model noise impacts on due to both arrival and departure operations on all runways at KBOS. The model is shown to reduce computational expense by 1-2 order of magnitude relative to traditional methods. The results of these example analyses show that increased lateral dispersion causes a significant noise reduction at higher noise levels directly below the flight track at the cost of wider contours at lower noise levels. Because of this, any decision to add or remove flight track lateral dispersion has highly localized impacts that depend on the geometry of the route and the population of the surrounding area, and thus must be closely analyzed on an individual basis.This work was sponsored by the FAA under ASCENT Center of Excellence Project 23, Cooperative Agreement 13-C-AJFE-MIT-008.by Callen T.

Problèmes de palynologie liés à la dérive des continents. Etude de quelques taxons tropicaux
No full textDie Verbreitung der tropischen und subtropischen Pollenarten aus disjunkten Arealen beidseitig des Atlantischen Ozeans kann durch mehrere Hypothesen erklärt werden : die Streuung über weite Entfernungen, der festländische Zusammenhang sei es durch Landbrücken oder durch Kontinentverschiebung, schliesslich die Polverschiebung allein. Mehrere Beispiele zeigen, dass die Kontinentaldrift-Theorie die Verbreitung der Pflanzenarten am besten erklärt, doch muss man bedenken, dass alle anderen erwähnten Möglichkeiten auch dazu beigetragen haben. Die Florenverbreitung ist das Resultat von direkten Uebergängen zwischen Amerika und Afrika (Ctenolophonaceae , Malpighiaceae, Icacinaceae) oder von Umwegen über Europa (Cneoraceae , Celastraceae, Icacinaceae, Malpighiaceae) oder Gondwana (Malpighiaceae) .Проблемы палинологии и их связь с континентальным дрейфом
Рассеивание на большие расстояния, непрерывность континентов обеспечиваемая континентальными мостами или слиянием континентов, перемещение полюсов, являются главними гипотезами при попытке объяснить распределение тропических и субтропических видов и видов трансатлантических на разбщенных ареалах. На основании многих примеров оказывается, что именно теория континентального дрейфа позволяет лучше всего объяснить распространение видов. Однако, следует не терять из виду, что все вышеупомянутые феномены способствовали распределению флоры ; последнее было реализовано или непосредственным проходом между Америкой и Африкой или через Европу и Гондвану.In order to explain the repartition of transatlantic tropical and subtropical species with apart areas, the principal hypotheses taken into account are the following : long distance dispersion, continental continuity due either to continental bridges or to the coalescence of continents and displacement of the poles. Several examples lead the author to think that the theory of the continental drift can explain most clearly the species dispersion. However, it is noticeable that all the phenomena previously mentioned took a part in the distribution of florae ; the latter was realized by means of transitions between America and Africa either directly (Ctenolophonaceae , Malpighiaceae, Icacinaceae), or by the intermediary of Europe (Cneoraceae , Celastraceae, Icacinaceae, Malpighiaceae) or Gondwana (Malpighiaceae ).Pour expliquer la répartition des espèces tropicales ou subtropicales, transatlantiques à aires disjointes, les principales hypothèses envisagées sont : la dispersion à longue distance, la continuité continentale, soit par les ponts continentaux, soit par la coalescence des continents, et le déplacement des pôles.
A l'aide de plusieurs exemples, il apparaît que c'est la théorie de la dérive des continents qui permet de mieux comprendre la dispersion des espèces. Toutefois, il faut considérer que tous les phénomènes cités précédemment ont contribué à la répartition des flores. Celle-ci s'est réalisée par des passages entre l'Amérique et l'Afrique, soit directement (pour les régions équatoriales : Gtenolophonaceae, Malpighiaceae, Icacina-ceae, ...), soit par l'intermédiaire de l'Europe (pour le bassin méditerranéen alors subtropical : Cneoraceae, Celastraceae, Icacinaceae, Malpighiaceae, ...), soit par l'intermédiaire du Gondwana.Lobreau-Callen Danielle.

Magneto-elastic interactions in terbium
No full textMaking use of the Hamiltonian for linear magneto-elastic coupling which has been proposed by Callen and Callen, expressions are deduced for changes in the velocity of acoustic waves in a terbium crystal, due to ferromagnetic ordering and the application of an external magnetic field. These calculations agree semi-quantitatively with the results of experimental measurements. The author has examined the extent to which this simple picture is applicable to explain the magnon-phonon interactions in terbium, which have been observed at finite wave vectors by inelastic neutron scatterin

No full textIntroduction Recent research has highlighted the adverse effect of high output volatility on economic growth, welfare, and poverty, particularly in developing countries 1 This underscores the importance of understanding the factors driving output volatility and the size of output drops, and the economic policies that could help reduce them. There are two strands of literature examining output volatility. The first strand is related to the literature on international business cycles and has focused on documenting stylized features of business cycles and their co-movement across countries. For example, Kose, Otrok, and Whiteman (2003) employ a Bayesian dynamic latent factor model to decompose output fluctuations into global, regional, and country-specific factors. Two key findings of this paper are, first, that there is a significant global component in individual countries' output fluctuations, and second, that country-* The paper has benefited from Chris Otrok's help in applying the Bayesian latent dynamic factor model. The author also thanks Tim Callen, Simon Johnson, Gene Leon, Sam Ouliaris, Raghuram Rajan, David Robinson, Miguel Savastano, and Marco Terrones for helpful comments and suggestions, and Stephanie Denis for research assistance. 1 It has been argued that economic crises resulting in output declines are not necessarily bad for long-run growth. Crises and recoveries, while intrinsically costly, can also facilitate resource reallocation from less to more efficient sectors and projects, à la Schumpeter, thereby possibly placing the economy on a higher--growth path. However
The equivalence between the entropy maximization Principle and the energy minimization Principle
No full textNeste trabalho, apresentamos a discussão original de Gibbs sobre a equivalência entre as condições de equilíbrio, a dizer, a condição de máxima entropia para uma energia determinada e a condição de mínima energia par uma entropia determinada – as quais são apresentadas como teoremas pelo autor. Na sequência, mostramos como tal discussão aparece em livros didáticos contemporâneos que apresentamos a Termodinâmica a partir de suas leis (lei zero mais as três leis). Comparamos tal apresentação com a discussão feita por Callen, em sua abordagem postulacional da Termodinâmica. Mostramos que parte da discussão de Gibbs foi perdida mesmo nos livros que abordam as leis. Ademais, discutimos que a abordagem de Callen não enfatiza o fato de que apesar de os princípios serem equivalentes, termalizar um sistema composto por processos distintos (um com energia constante e outro com entropia constante) conduz a diferentes valores de temperatura. Além de resolver o problema analiticamente, apresentamos uma análise gráfica do problema. Ao final, discutimos implicações para o ensino de termodinâmica.In this paper, we present Gibbs’ original discussion on the equivalence between equilibrium conditions, i.e., a maximum entropy condition for a given energy and the minimum energy condition for a given entropy – which are presented as theorems by the author. Next, we show how such a discussion appears in contemporary textbooks that present Thermodynamics from its laws (law zero plus the three laws). We compare this presentation with the discussion made by Callen, in his postulational approach to Thermodynamics. We show that part of Gibbs’ discussion has been lost even in textbooks dealing with the laws. Furthermore, we argue that Callen’s approach does not emphasize the fact that although the principles are the same, thermalizing a system composed of distinct processes (one with constant energy and the other with constant temperature) leads to different temperature values. In addition to solving the problem analytically, we present a graphical analysis of the problem. At the end, we discuss implications for thermodynamics teaching
