The Pulsation-Rotation Interaction: Greatest Hits and the B-Side
It has long been known that rotation can have an appreciable impact on
stellar pulsation --- by modifying the usual p and g modes found in the
non-rotating case, and by introducing new classes of mode. However, it's only
relatively recently that advances in numerical simulations and complementary
theoretical treatments have enabled us to model these phenomena in any great
detail. In this talk I'll review highlights in this area (the 'Greatest Hits'),
before considering the flip side (or the 'B-side', for those of us old enough
to remember vinyl records) of the pulsation-rotation interaction: how pulsation
can itself influence internal rotation profiles.Comment: 8 pages; to appear in Proc. IAU Symposium 301: Precision

The Difficult Transition from Military to Civilian Life
Military service is difficult, demanding and dangerous. But returning to civilian life also poses challenges for the men and women who have served in the armed forces, according to a recent Pew Research Center survey of 1,853 veterans. While more than seven-in-ten veterans (72%) report they had an easy time readjusting to civilian life, 27% say re-entry was difficult for them -- a proportion that swells to 44% among veterans who served in the ten years since the Sept. 11, 2001, terrorist attacks. Why do some veterans have a hard time readjusting to civilian life while others make the transition with little or no difficulty? To answer that question, Pew researchers analyzed the attitudes, experiences and demographic characteristic of veterans to identify the factors that independently predict whether a service member will have an easy or difficult re-entry experience. Using a statistical technique known as logistic regression, the analysis examined the impact on re-entry of 18 demographic and attitudinal variables

Studies on the Hemoglobin of Cooley's Anemia and Cooley's Trait
The diseases sickle cell anemia and Cooley's anemia (also known as thalassemia or Mediterranean anemia) have associated with them "minor" or "trait" forms of the disease in which the symptomatology is minimal, and the abnormalities in the red cells are correspondingly less. Extensive genetic studies carried out on these diseases [1-4] have led to the conclusion that in each case the trait is inherited as a Mendalian dominant, the person being heterozygous in the sickle cell gene or Cooley's gene. Homozygosity in either of these genes leads to the corresponding anemia.
Our understanding of sickle cell anemia has improved considerably with the discovery of an abnormal hemoglobin and a molecular interpretation of the pathological behavior of the red cell. [5] In that disease it was possible to demonstrate heterozygosity and homozygosity directly, by observing varying amounts of the abnormal hemoglobin.
Liquori [6] has recently reported the pr'esence of fetal hemoglobin in cases of Cooley's anemia. We have carried out a number of experiments which support his findings, and have extended the investigation to include cases of Cooley's trait, for which no fetal hemoglobin was found. A hypothesis is advanced to explain these facts
Moving Toward Healing: Trauma and Violence and Boys and Young Men of Color
The purpose of this brief is to highlight the great burden that trauma, violence, adversity, and the social determinants of health impose on the health of boys and men of color. To protect BYMOC from the potential harm inflicted on them—and to mobilize the resilience and promise these young people hold—providers, leaders and policymakers must understand the physical, emotional and societal effects of trauma, violence, and adversity. They must also recognize the implicit and explicit racism and stigma faced by BYMOC. Only with this understanding can leaders effect the fundamental transformation to ensure that BYMOC heal, thrive, and realize their fullest potential
