This anthology is the first sustained examination of American involvement in World War II through an environmental lens. World War II was a total and global war that involved the extraction, processing, and use of vast quantities of natural resources. The wartime military-industrial complex, the 'Arsenal of Democracy,' experienced tremendous economic growth and technological development, employing resources at a higher intensity than ever before. The war years witnessed transformations in American agriculture; the proliferation of militarized landscapes; the popularization of chemical and pharmaceutical products; a rapid increase in energy consumption and the development of nuclear energy; a remaking of the nation's transportation networks; a shift in population toward the Sunbelt and the West Coast; a vast expansion in the federal government, in conjunction with industrial firms; and the emergence of environmentalism. World War II represented a quantitative and qualitative leap in resource use, with lasting implications for American government, science, society, health, and ecology.
Different manufacturers recommend different levels of disinfection for oxygen nipple and nut adaptors, also known as Christmas-tree adaptors (CTAs). We aimed to determine the bacterial contamination rates of CTAs before and after clinical use and whether disinfection wipes effectively eliminate bacteria from CTAs.
CTAs were swabbed for bacteria directly from the shipment box or after use in a medical intensive care unit to determine levels of contamination. CTAs were also inoculated in the laboratory with a variety of bacteria and disinfected with either 0.5% hydrogen peroxide (Oxivir 1) or 0.25% tetra-ammonium chloride with 44.50% isopropyl alcohol (Super Sani-Cloth), and the effectiveness of each wipe was determined by comparing the bacterial recovery before and after disinfection.
CTAs exhibit low levels of bacterial burden before and after clinical use. Both disinfecting wipes were effective at removing bacteria from the CTAs.
Low-level disinfection of CTAs is appropriate prior to redeployment in the clinical setting.
The climate crisis requires nations to achieve human well-being with low national levels of carbon emissions. Countries vary from one another dramatically in how effectively they convert resources into well-being, and some nations with low levels of emissions have relatively high objective and subjective well-being. We identify urgent research and policy agendas for four groups of countries with either low or high emissions and well-being indicators. Least studied are those with low well-being and high emissions. Understanding social and political barriers to switching from high-carbon to lower-carbon modes of production and consumption, and ways to overcome them, will be fundamental.
The science of studying diamond inclusions for understanding Earth history has developed significantly over the past decades, with new instrumentation and techniques applied to diamond sample archives revealing the stories contained within diamond inclusions. This chapter reviews what diamonds can tell us about the deep carbon cycle over the course of Earth’s history. It reviews how the geochemistry of diamonds and their inclusions inform us about the deep carbon cycle, the origin of the diamonds in Earth’s mantle, and the evolution of diamonds through time.
Clay minerals from the Indus Canyon and eastern clinoform since ~12 ka are uniformly rich in smectite and illite, similar to those from the Holocene Indus flood plains. A systematic enrichment of smectite in the proximal delta compared to the canyon and eastern clinoform argues for preferential capture of smectite close to the river mouth since ~12 ka. There is a rapid shift to a more smectite-rich assemblage in the canyon and eastern clinoform after ~5 ka. This change is probably caused by a change in sediment source, with less direct flux from the Himalaya and more erosion of older, weathered, smectite-rich sediment from the Indus River flood plains, driven by incision of the Indus and its tributaries into the floodplain as summer monsoon rains weakened. This influx of smectite is consistent with lower kaolinite/smectite values since ~5 ka. The onset of large-scale agricultural activities since ~5 ka, especially starting with the Harappan Civilization, may also have enhanced incision and erosion of floodplain sediments over the same time period. This study reports for the first time how monsoon strength variations since ~12 ka affected the clay mineral assemblages and sediment provenance in a major submarine canyon.
The morphology and growth habits of Evactinopora species of the Evactinoporidae (new family) are documented. This distinctive family of free-living bryozoans has a radial colony form at all growth stages. During a brief attachment phase on a hard substrate, the colony morphology grew as an expanding cone with vertical folds. Following detachment of the nascent colony from this hard substrate, it settled on soft sediment and the free-living expanding colony acquired a star-like form by producing slender outrigger rays. Continued growth produced a radial array of vertical vanes containing feeding autozooecia. The colony maintained a vertical orientation on soft sediment by means of outrigger rays and secretion of solid skeleton on the colony base that provided ballast. The radial growth pattern, outrigger rays, and vertical vanes developed as adaptive characters suitable for free-living life on soft sediment. North American species of Evactinopora are redefined and described taxonomically on the basis of zoarial and zooecial characters and a new species, Evactinopora mangeri, erected. The new family Evactinoporidae is established on the basis of the novel characters of early colony detachment from a hard surface, radial growth pattern through life, generation of outrigger rays, and growth of vertical vanes from the top of rays.
A national need is to prepare for and respond to accidental or intentional disasters categorized as chemical, biological, radiological, nuclear, or explosive (CBRNE). These incidents require specific subject-matter expertise, yet have commonalities. We identify 7 core elements comprising CBRNE science that require integration for effective preparedness planning and public health and medical response and recovery. These core elements are (1) basic and clinical sciences, (2) modeling and systems management, (3) planning, (4) response and incident management, (5) recovery and resilience, (6) lessons learned, and (7) continuous improvement. A key feature is the ability of relevant subject matter experts to integrate information into response operations. We propose the CBRNE medical operations science support expert as a professional who (1) understands that CBRNE incidents require an integrated systems approach, (2) understands the key functions and contributions of CBRNE science practitioners, (3) helps direct strategic and tactical CBRNE planning and responses through first-hand experience, and (4) provides advice to senior decision-makers managing response activities. Recognition of both CBRNE science as a distinct competency and the establishment of the CBRNE medical operations science support expert informs the public of the enormous progress made, broadcasts opportunities for new talent, and enhances the sophistication and analytic expertise of senior managers planning for and responding to CBRNE incidents.
Over the past several years there has been considerable interest in the relation between emotion dysregulation and non-suicidal self-injury (NSSI), particularly given that rates of NSSI have been increasing and NSSI is a critical risk factor for suicidal behavior. To date, however, no synthesis of empirical findings exists.
The present study presents a comprehensive meta-analytic review of the literature on the association between NSSI and emotion dysregulation. A total of 48 publications, including 49 independent samples, were included in this analysis.
Overall, a significant association was found between emotion dysregulation and NSSI (pooled OR = 3.03 [95% CI = 2.56–3.59]). This association was reduced but remained significant (OR = 2.40 [95% CI = 2.01–2.86]) after adjustment for publication bias. Emotion dysregulation subscales most strongly associated with NSSI included limited access to regulation strategies, non-acceptance of emotional responses, impulse control difficulties, and difficulties engaging goal-directed behavior. Lack of emotional awareness/clarity and cognitive aspects of dysregulation yielded weaker, yet significant, positive associations with NSSI.
Findings support the notion that greater emotion dysregulation is associated with higher risk for NSSI among individuals across settings, regardless of age or sex. Furthermore, findings reveal facets of dysregulation that may have unique implications for NSSI. This meta-analysis highlights the importance of better understanding emotion dysregulation as a treatment target for preventing NSSI.
Cougar Mountain Cave is located in Oregon's Fort Rock Basin. In 1958, avocationalist John Cowles excavated most of the cave's deposits and recovered abundant fiber, lithic, wood, and osseous artifacts. A crew from the University of California, Davis returned to the site in 1966 to evaluate the potential for further research, collecting additional lithic and fiber artifacts from disturbed deposits and in situ charcoal from apparently undisturbed deposits. Because Cowles took few notes or photographs, the Cougar Mountain Cave collection—most of which is housed at the Favell Museum in Klamath Falls, Oregon—has largely gone unstudied even though it contains diagnostic artifacts spanning the Holocene and, potentially, the terminal Pleistocene. We recently submitted charcoal and basketry from the site for radiocarbon dating, providing the first reliable sense of when Cougar Mountain Cave was first occupied. Our results indicate at least a Younger Dryas age for initial occupation. The directly dated basketry has provided new information about the age ranges and spatial distributions of diagnostic textile types in the northwestern Great Basin.
The early Middle Ages saw a major expansion of cereal cultivation across large parts of Europe thanks to the spread of open-field farming. A major project to trace this expansion in England by deploying a range of scientific methods is generating direct evidence for this so-called ‘Medieval Agricultural Revolution’.
A more efficient utilisation of marine-derived sources of dietary n-3 long-chain PUFA (n-3 LC PUFA) in cultured Atlantic salmon (Salmo salar L.) could be achieved by nutritional strategies that maximise endogenous n-3 LC PUFA synthesis. The objective of the present study was to quantify the extent of n-3 LC PUFA biosynthesis and the resultant effect on fillet nutritional quality in large fish. Four diets were manufactured, providing altered levels of dietary n-3 substrate, namely, 18 : 3n-3, and end products, namely, 20 : 5n-3 and 22 : 6n-3. After 283 d of feeding, fish grew in excess of 3000 g and no differences in growth performance or biometrical parameters were recorded. An analysis of fatty acid composition and in vivo metabolism revealed that endogenous production of n-3 LC PUFA in fish fed a diet containing no added fish oil resulted in fillet levels of n-3 LC PUFA comparable with fish fed a diet with added fish oil. However, this result was not consistent among all treatments. Another major finding of this study was the presence of abundant dietary n-3 substrate, with the addition of dietary n-3 end product (i.e. fish oil) served to increase final fillet levels of n-3 LC PUFA. Specifically, preferential β-oxidation of dietary C18n-3 PUFA resulted in conservation of n-3 LC PUFA from catabolism. Ultimately, this study highlights the potential for endogenous synthesis of n-3 LC PUFA to, partially, support a substantial reduction in the amount of dietary fish oil in diets for Atlantic salmon reared in seawater.
Richard Curtin has directed the University of Michigan's consumer sentiment surveys for more than four decades. His analyses of recent trends in consumer expectations are regularly covered in the worldwide press. In this book, Curtin presents a new theory of expectations. Whereas conventional theories presume that consumers play a passive role in the macro economy, simply reacting to current trends in incomes, prices, and interest rates, Curtin proposes a new empirically consistent theory. He argues that expectations are formed by an automatic process that utilizes conscious and nonconscious processes, passion and reason, information from public and private sources, and social networks. Consumers ultimately reach a decision that serves both the micro decision needs of individuals and reflects the common influence of the macro environment. Drawing on empirical observations, Curtin not only demonstrates the importance of consumer sentiment, but also how it can foreshadow the cyclical turning points in the economy.
