While nuclear weapons were conceived to end a war, in the aftermath of their operational use at Hiroshima and Nagasaki, they became the central (and controversial) means to prevent a war. Nuclear deterrence formed the foundation of U.S. Cold War doctrine and the basis of an extended security guarantee to our allies. But the Cold War ended one-quarter century ago, and questions about the efficacy of deterrence, the need for nuclear weapons, and the ethics surrounding them have resurfaced as some call for further major reductions in inventory or the complete elimination of the U.S. nuclear arsenal. Discussed from the perspective of a military practitioner, this essay highlights the continuing need for U.S. nuclear weapons in a global security environment that is highly complex and uncertain, and describes the means by which the credibility of the nuclear portion of the strategic deterrent is being preserved even as the role and prominence of these weapons have been reduced.

Credible, reliable and consistent information to the public, as well as health professionals and decision makers, is crucial to help navigate uncertainty and risk in times of crisis and concern. Traditionally, information and health communications issued by respected and established government agencies have been regarded as factual, unbiased and credible. The U.S. Centers for Disease Control and Prevention (CDC) is such an agency that addresses all aspects of health and public health on behalf of the U.S Government for the benefit of its citizens. In July 2020, the CDC issued guidelines on reopening schools which resulted in open criticism by the U.S. President and others, prompting a review and publication of revised guidelines together with a special “Statement on the Importance of Reopening Schools under COVID-19.” We hypothesize that this statement introduced bias with the intention to shift the public perception and media narrative in favor of reopening of schools. Using a mixed methods approach, including an online text analysis tool, we demonstrate that document title and structure, word frequencies, word choice, and website presentation did not provide a balanced account of the complexity and uncertainty surrounding school reopening during the COVID-19 pandemic. Despite available scientific guidance and practical evidence-based advice on how to manage infection risks when reopening schools, the CDC Statement was intentionally overriding possible parent and public health concerns. The CDC Statement provides an example of how political influence is exercised over the presentation of science in the context of a major pandemic. It was withdrawn by the CDC in November 2020.

ABSTRACTOver the past decade, NASA, under a succession of rotary-wing programs, has been moving towards coupling multiple discipline analyses to evaluate rotorcraft conceptual designs. Handling qualities is one of the component analyses to be included in such a future Multidisciplinary Analysis and Optimization framework for conceptual design of Vertical Take-Off and Landing (VTOL) aircraft. Similarly, the future vision for the capability of the Concept Design and Assessment Technology Area of the U.S Army Aviation Development Directorate also includes a handling qualities component. SIMPLI-FLYD is a tool jointly developed by NASA and the U.S. Army to perform modelling and analysis for the assessment of the handling qualities of rotorcraft conceptual designs. Illustrative scenarios of a tiltrotor in forward flight and a single-main rotor helicopter at hover are analysed using a combined process of SIMPLI-FLYD integrated with the conceptual design sizing tool NDARC. The effects of variations of input parameters such as horizontal tail and tail rotor geometry were evaluated in the form of margins to fixed- and rotary-wing handling qualities metrics and the computed vehicle empty weight. The handling qualities Design Margins are shown to vary across the flight envelope due to both changing flight dynamics and control characteristics and changing handling qualities specification requirements. The current SIMPLI-FLYD capability, lessons learned from its use and future developments are discussed.

Self assessment should include asking ourselves how we might allocate our investments to enhance the impact of our publication portfolio. I develop an easily implemented scientific investment portfolio analysis tool based on citations. Using Google Scholar data, I provide examples at individual and institutional levels for two cases in the biological sciences. Visualizing these data in three dimensions reveals striking degrees of structure and variation in how investments have been made and in how they have performed among subdisciplines or scientific market sectors. Legacy and time-corrected performance also provide contrasting views. This approach provides a quantitative way to assess market sectors in relation to each other in a way that should be broadly useful in planning future scientific investments for individuals, departments, or institutions.

Internationalization in the community college sector serves many purposes that align with the local and national contexts in which an institution is situated. One method of assessing how international efforts have become institutionalized is through the analysis of internationalization plans. Prior research examining internationalization plans and agendas is centered on the four-year sector, and studies on the two-year sector and comparative studies are scarce. This article addresses that gap by analyzing four community college internationalization plans in the U.S. and Canada. We use the textual analysis tool, Voyant, to examine how internationalization is operationalized in these two national contexts. Our findings indicate that there is little emphasis on mobility and language programs, despite the presence of these internationalization strategies in institutional or national policies. The documents also show greater quantification of goals related to internationalization and lesser specificity regarding intercultural activities. Implications and recommendations for future research are offered.
