Unmanned air system (UAS/UAV) noise and urban mobility noise were the subject of two National Academy of Engineering (NAE) hosted workshops under the auspices of the Technology of Quieter America (TQA) program. Both workshops were organized by the INCE Foundation in cooperation with the U.S. National Aeronautics and Space Administration (NASA) and the U.S. Federal Aviation Administration (FAA). The first workshop "UAS and UAV (Drone): Noise Emissions and Noise Control Engineering Technology" was held in Washington, DC in December, 2018. manufacturers, users, U.S. government agencies, universities, consultants and professional societies. The second was an e-workshop "Aerial Mobility: Noise Issues and Technology" in December, 2020. Participants at each workshop included representatives from manufacturers (US and international), users, U.S. government agencies, academia, consultants, professional societies, and law firms. Topics included: modelling, testing, psychoacoustics, community impact, noise reduction strategies, measurement techniques, and uses of both UAS/UAVs and aerial mobility.

More environmentally friendly aircraft designs, particularly with regard to noise, was a Technology for a Quieter America (TQA) workshop hosted by the National Academy of Engineering (NAE) held in May 2017. This workshop titled "Commercial Aviation: A New Era", centered on the importance of commercial aviation to the U.S. economy, and what it will take for the U.S. to maintain global leadership in the aviation sector, including a forward-looking topic on more environmentally friendly aircraft designs. A principal focus of the workshop was the necessary step-changes in aircraft engineering technology that must be addressed with the development and testing of flight demonstrators together with significantly increased funding of public-private partnerships. Government agencies which participated included NASA, the Federal Aviation Administration, and the Department of Housing and Urban Development (HUD). There was also substantial participation from the aviation industry, airports, airlines, non-government organizations and academia.

Native American dancers in the 1890s rebelling against the U.S. government’s failure to uphold treaties protecting land rights and rations were accused of fomenting a dancing ‘craze’. Their dancing—which hoped for a renewal of Native life—was subject to intense government scrutiny and panic. The government anthropologist James Mooney, in participant observation and fieldwork, described it as a religious ecstasy like St. Vitus’s dance. The Ghost Dance movement escalated with the proliferation of reports, telegraphs, and letters circulating via Washington, DC. Although romantically described as ‘geognosic’—nearly mineral—ancestors of the whites, Native rebels in the Plains were told to stop dancing so they could work and thus modernize; their dancing was deemed excessive, wasteful, and unproductive. The government’s belligerently declared state of exception—effectively cultural war—was countered by one that they performed ecstatically. ‘Wasted’ energy, dancers maintained, trumped dollarization—the hollow ‘use value’ of capitalist biopower.

This study examines infant fatalities that occurred while sharing a sleep surface. Fatality data reported to the U.S. Consumer Product Safety Commission (CPSC) during the time period January, 2013 through December, 2017 and involving infants through age 10 months were reviewed. 1,587 Cases were analyzed on the following variables: infant age and sex; sleep environment by product; cause of death; fatality pattern; and breastfeeding, where it was mentioned. 97% Of deaths were due to some form of asphyxia. Adult beds were associated with 78% of shared sleep fatalities, and the primary fatality pattern was overlay (35.4%)/probable overlay (8.8%). Infants <3 months made up 65% of fatalities. The data reflect that bedsharing continues, despite AAP guidelines to the contrary, and that overlay is the primary hazard pattern to be addressed. This paper discusses potential risk reduction strategies that may reduce the potential for overlay fatalities.

&lt;p&gt;The American Geosciences Institute in cooperation with its member societies has developed the Framework for Addressing Racial and Ethnic Equity in Geosciences Professional Societies.&amp;#160; The geoscience societies are a pivotal area to influence the culture of the geosciences, and in response to the events of June 2020, many societies determined they needed to directly act on the issue of equity in the geosciences. Being birthed from a federation of US-centric organizations, the Framework has clear US-aligned approaches and boundaries.&amp;#160; However, the baseline proposed actions are fundamentally universal and meet the goal of the authoring committee to provide a framework from which we hope geoscience organizations of all types would use it to craft their own specific action plan and policies.&amp;#160;&amp;#160; A critical component of this framework for the committee was to ensure definable actions were included.&amp;#160;&amp;#160; Some of these suggested actions and their intended extensions will be discussed.&amp;#160; Additionally, ongoing conversations among the societies, with the US National Academy of Sciences Board on Earth Science and Resources, and other science organizations have begun to examine what the path forward looks like.&amp;#160;&amp;#160; One area that AGI particularly is concerned about is the process of measuring progress.&amp;#160;&amp;#160; Understanding and recognizing the impacts of efforts like this is critical to ensure agile responses for success.&amp;#160;&amp;#160; But with AGI's intimate knowledge of much of the U.S. federal data, some of the ambiguities and definitional challenges within the US system complicates the ability to directly measure progress and for which further discussion of what success looks like is critically needed.&amp;#160;&amp;#160;&lt;/p&gt;

This Jet Engine Titanium Quality Committee (JETQC) paper describes industry quality improvements since 1990. Quality refers to freedom from melt-related hard-alpha and high-density inclusions (HDI). JETQC, formed under the auspices of the U.S. Federal Aviation Administration (FAA) following the Sioux City aircraft accident in 1989, is comprised of U.S., E.U. and Japanese aircraft engine manufacturers to address the quality of premium / rotor quality titanium alloy production. Titanium suppliers provide melt-related inclusion data. JETQC focuses on hard-alpha and HDI inclusion rates in premium quality (PQ) titanium alloy products for critical rotating aircraft engine applications. PQ materials typically are produced via triple vacuum arc re-melt (3XVAR) or hearth melt VAR (HMVAR) processes, but more recently, the Skull plus VAR (SVAR) process has been introduced. Hard-alpha rates have continued to decline over the last decade primarily for the HMVAR process. HDI rates declined in the early 90’s, but more recently the overall rate has stayed approximately constant with inclusions confined to the 3XVAR process. Combining the trends for both hard-alpha and HDIs, the HMVAR process has demonstrated in recent years to be higher quality compared with the 3XVAR process.
