This paper includes a brief history of the of used by the Naval Academy’s sailing program and their uses, the development of the criteria used to define the yawl replacement, and finally, a description of the replacement vessel. This class of vessel will eventually replace all of the Academy yawls and the other sail training craft now used by the Sailing Squadron.

Albert Abraham Michelson was born on December 19, 1852, at Strelno in Posen, now restored to Poland. When he was two years old, he was taken by his parents, Samuel Michelson and Rosalie (Przlubska), to the United States, and, after some fifteen years spent in Virgina City, Nevada, where his brother Charles was born, San Francisco became their home. There his sister Miriam, the author, was born, and the boy attended the high school. He was given, in unusual circumstances, an appointment in the U.S. Naval Academy at Annapolis, and after graduating in 1873 he became a midshipman in the U.S. Navy for two years and was afterwards appointed instructor in physics and chemistry in the Naval Academy in 1875, holding the appointment until 1879. His next year was spent in the Nautical Almanac Office in Washington, and then he studied for two years at the College of France, and at Heidelberg and Berlin. In 1882 he became Professor of Physics in the Case School of Applied Science at Cleveland, Ohio. After seven years he went as Professor of Physics to Clark University, Worcester, Mass., and remained there until 1892. He was then appointed Professor at the head of the Ryerson Physical Laboratory, Chicago ; this appointment he held until shortly before his death, which occurred on May 9, 1931. He married Miss Edna Stanton of Lake Forest, Illinois, in 1899, and they had a son and two daughters. This in brief contains the history of his official appointments : how he filled the various posts is another matter.

The following was the author’s presidential address at the annual meeting of the Pacific Coast Branch, American Historical Association, in Northridge, California, on August 4, 2017. The twentieth-century visual history of the U.S.-Mexico borderlands, la frontera, offers a rich set of representations of the shared border environments. Photographs, distributed in the United States and in Mexico, allow us to trace emerging ideas about the border region and the politicized borderline. This essay explores two border visualization projects—one centered on the Mexican Revolution and the visual vocabulary of the Mexican nation and the other on the repeat photography of plant ecologists—that illustrate the simultaneous instability and power of borders.

That does the future hold for U.S.-Mexican relations? Optimistic assessments usually point to the high degree of interpenetration between the two societies, the recent history of intergovernmental cooperation, and the commonality of basic interests. Developments in one country have significant impact on the other, a process that now works both ways: the 1982 economic crisis in Mexico created serious difficulties for retailers on the U.S. side of the border, Mexico's subsequent cutbacks in imports prompted the loss of 200,000 jobs in the U.S., and Mexico's struggles with its international debt have crucial implications for banks in the U.S. Each country needs the other, and this kind of “interdependence” creates mutuality of purpose. According to this logic, the rational pursuit of national goals will build and fortify harmonious bilateral relations.

ABSTRACT Introduction The six-item Foot Posture Index (FPI-6) was previously developed as an assessment tool to measure the posture of the foot across multiple segments and planes. It was derived from a criterion-based observational assessment of six components of each foot during static standing. The association between abnormal foot posture and musculoskeletal injuries remains unclear and is in of need further exploration. Hypothesis/Purpose The purpose of this study was to assess the association between foot biomechanics and self-reported history of musculoskeletal pain or injury. Study Design Retrospective, cross-sectional study of collegiate football players at the U.S. Naval Academy. Materials and Methods For each athlete, data were recorded on height, weight, self-reported history of pain or injury, and foot posture, which was measured using a FPI-6 with each item measuring the degree of pronation/supination. The primary outcome was each athlete’s maximum deviation from neutral posture across the six-item index (FPImax). The prespecified primary analysis used generalized linear models to measure the association between FPImax and self-report history of pain or injury. Exploratory analyses measured the association using penalized regression (L1-norm) and a type of tree-based ensemble known as extreme gradient boosting (XGBoost). Results Data were collected on 101 athletes, 99 of whom had sufficient body mass index (BMI) data to be included for analysis. Among the 99 athletes, higher FPImax was associated with a prior history of musculoskeletal pain (odds ratio [OR] 1.15, 95% confidence interval [CI] 0.97 to 1.35), although the sample size was too small for the association to be significant with 95% CI (P = .107). FPImax was not associated with a history of knee injury/pain (OR 0.98, 95% CI 0.83 to 1.15, P = .792), nor with a history of ankle/foot injury or pain (OR 1.04, 95% CI 0.90 to 1.21, P = .599). From the L1-penalized model, the FPI components with the strongest linear associations were the L6, R2, R1-squared, and FPImax. From the XGBoost model, the most important variables were FPItotal, BMI, R1, and R2. Conclusions The U.S. Naval Academy football players whose foot postures deviated from neutral were more likely to have reported a previous history of musculoskeletal pain. However, this deviation from normal was not strongly associated with a specific history of pain or injury to the knee, ankle, or foot. Clinical Relevance The information ascertained from this study could be used to better inform clinicians about the value of the FPI in predicting or mitigating injuries for varsity football athletes.

Life beyond 1MeV – like life after 40 – is not too different unless one takes advantage of past experience and is receptive to new opportunities. At first glance, the returns on performing electron microscopy at voltages greater than 1MeV diminish rather rapidly as the curves which describe the well-known advantages of HVEM often tend towards saturation. However, in a country with a significant HVEM capability, a good case can be made for investing in instruments with a range of maximum accelerating voltages. In this regard, the 1.5MeV KRATOS HVEM being installed in Berkeley will complement the other 650KeV, 1MeV, and 1.2MeV instruments currently operating in the U.S. One other consideration suggests that 1.5MeV is an optimum voltage machine – Its additional advantages may be purchased for not much more than a 1MeV instrument. On the other hand, the 3MeV HVEM's which seem to be operated at 2MeV maximum, are much more expensive.

In his somewhat controversial book Remnants of Auschwitz, Agamben makes brief reference to Theodor Adorno’s apparently contradictory remarks on perceptions of death post-Auschwitz, positions that Adorno had taken concerning Nazi genocidal actions that had seemed also to reflect something horribly errant in the history of thought itself. There was within such murderous acts, he had claimed, a particular degradation of death itself, a perpetration of our humanity bound in some way to affect our perception of reason itself. The contradictions regarding Auschwitz that Agamben senses to be latent within Adorno’s remarks involve the intuition ‘on the one hand, of having realized the unconditional triumph of death against life; on the other, of having degraded and debased death. Neither of these charges – perhaps like every charge, which is always a genuinely legal gesture – succeed in exhausting Auschwitz’s offense, in defining its case in point’ (RA 81). And this is the stance that Agamben wishes to hammer home quite emphatically vis-à-vis Adorno’s limitations, ones that, I would only add, seem to linger within Agamben’s own formulations in ways that he has still not come to reckon with entirely: ‘This oscillation’, he affirms, ‘betrays reason’s incapacity to identify the specific crime of Auschwitz with certainty’ (RA 81).
