Abstract Although necromass decay rates are limited by the slowest portions to decompose, most decomposition studies examine only the earliest stage of decay. As such, these studies run the risk of yielding misleading results regarding the relative contributions of different decomposers. For example, the contributions of macroinvertebrates to wood decomposition remain mostly unknown beyond the first 50% of mass lost, despite drastic changes in substrate conditions over time. We sought to clarify how the macroinvertebrate contribution to decay changes over the course of wood decomposition in the Southeastern United States—a region with a long history of wood decomposition research. To this end, we (1) compiled data from published studies comparing wood decay with and without macroinvertebrates; and (2) conducted a field study assessing wood mass loss, with and without macroinvertebrate access, at three sites across the region over four years. With these combined data, we analyzed macroinvertebrate contribution as decay progressed, revealing a quadratic relationship, wherein macroinvertebrate contribution increased early in decomposition and then began to decline as decay progressed. Strong local site effects, particularly the abundance and activity of termites, determine the time required for wood to reach this point of mass loss.

Abstract Sightings of unidentified flying objects (UFOs) or unidentified anomalous phenomena (UAP) have been reported throughout history. Given the potential security and safety risks they pose, as well as scientific curiosity, there is increasing interest in understanding what these sighting reports represent. We approach this problem as an important one of the human experience and that can be examined through a geographical lens: what local factors may increase or decrease the number of sighting reports? Using a Bayesian regression method, we test hypotheses based on variables representing sky view potential (light pollution, tree canopy, and cloud cover) and the potential for objects to be present in the sky (aircraft and military installations). The dependent variable includes over 98,000 publicly reported UAP sightings in the conterminous United States during the 20-year period from 2001 to 2020. The model results find credible correlations between variables that suggest people see more “phenomena” when they have more opportunity to. This analysis is one of few investigations of UAP sighting reports at a national scale providing context to help examine individual reports. Given that these objects are labeled unidentifiable in the personal sense, there are many natural and/or human based explanations worth exploring.

The John Day region of central Oregon, United States contains ∼50 million years of near-continuous, fossiliferous sedimentation, representing one of the world’s richest archives of Cenozoic terrestrial ecosystems and climate. Stable isotope proxy data from this region are commonly used to infer the elevation history of the Cascades, which intercept westerly moisture in transit to the John Day region. However, the Blue Mountains, which accreted in the Mesozoic, create a region of local high topography that can confound signals of Cascades uplift. John Day deposits, including the John Day Formation, are divided into an eastern facies located within the Blue Mountains and a western facies in the adjacent plains. As a result, the Blue Mountains may have supported gradients in climate and ecology between the eastern and western facies, and constraining these gradients is necessary for reconstructing past topography and ecosystem change. In order to define the Cenozoic extent and magnitude of Blue Mountains topography we use oxygen isotopes in authigenic clay minerals to construct a spatially resolved map of local elevation. We find that the oxygen isotope composition of clay minerals within the Blue Mountains is ∼3‰ lower than in the adjacent high plains, and this offset is mostly constant throughout our record (spanning ∼50 – 5 Ma). We attribute this offset to Blue Mountains topography, either directly from upslope rainout or indirectly through the effect of elevation on local variations in precipitation seasonality. Our results highlight the importance of local topographic features in regional paleotopography reconstructions and provide important biogeographical context for the rich paleo-floral and -faunal records preserved in John Day sediments.

The U.S. is known as a nation founded on and committed to the institution of private property. For the first 125 years of its history there was limited regulatory-based social management of private property. Beginning in the early 20th century there began a century-long process of change. This change was characterized by increasing amounts of public regulation at the local, state and national levels. These changes were often prompted by one or more types of disasters (significant social, economic, and ecological disruptions). Always these changes were socially contentious but the social contention became particularly acrimonious in the late 20th century.This paper examines the interactions among disasters, public regulation of private property and social conflict over this regulation throughout the 20th century in the United States. It concentrates on explaining why, even though social conflict has always been present when regulation has been proposed or newly implemented, social conflict became a dominant component of social and policy discourse in the late 20th century.

While the explicit aestheticization of modern architecture during MoMA’s first decade of exhibitions is well known, it is too often forgotten that this interpretation was countered from the beginning by exhibitions advancing an understanding of architecture that emphasized its social effects. Coinciding with America’s first large-scale public housing projects, part of the New Deal’s attempt to end the Great Depression through relief, recovery, and reform, MoMA installed several shows advocating for public housing during the 1930s — an overlooked facet of the museum’s well-documented history. This article explores how MoMA was instrumental in introducing and promoting the concept of public housing to the American public by cooperating on several exhibitions with local and federal public housing authorities, such as 'Housing Exhibition of the City of New York' (1934), 'Architecture and Government Housing' (1936) and 'Houses and Housing' (1939). Figures involved in several of these exhibitions such as self-acclaimed ‘housing expert’ Catherine Bauer were also active as part of governmental and non-governmental housing organizations, creating the laws that radically reformed housing in the United States. And yet, these exhibitions simultaneously presented housing as a distinct subcategory of architecture — a category in which quantity and affordability were valued over excellent design. The housing exhibitions made the living environments of the poor visible but perpetuated the divide between a prized elitist modernized aesthetics and built environments for the working-class masses.

Abstract Background Glaucoma is a leading cause of blindness in developed countries. Primary open-angle glaucoma (POAG), the most prevalent clinical subtype of glaucoma in the United States, affects African Americans at a higher rate compared with European Americans. Risk factors identified for POAG include increased age and family history, which coupled with heritability estimates, suggest this complex condition is associated with genetic and environmental factors. To date, several genome-wide studies have identified loci significantly associated with POAG risk, but most of these studies were performed in populations of European-descent. Methods To identify population-specific and trans-population genetic associations for POAG, we genotyped 11,521 African Americans using the Illumina Metabochip as part of the Epidemiologic Architecture for Genes Linked to Environment (EAGLE) study accessing BioVU, the Vanderbilt University Medical Center’s biorepository linked to de-identified electronic health records. Among this study population, we identified 138 cases of POAG and 1376 controls and performed Metabochip-wide tests of association. We also estimated local genetic ancestry at CDKN2B-AS1, a POAG-associated locus established in European-descent populations. Results Overall, we did not identify significant single SNP-POAG associations after adjusting for multiple testing. We did, however, detect a significant association between POAG risk and local African genetic ancestry at CDKN2B-AS1, where on average cases were of 90% African descent compared with controls at 58% (p = 2 × 10− 6). Conclusions These data suggest that CDKN2B-AS1 is an important locus for POAG risk among African Americans, warranting further investigation to identify the variants underlying this association.

Background and objective Lung cancer is the leading cause of cancer-related death in China. The results from a randomized controlled trial using annual low-dose computed tomography (LDCT) in specific high-risk groups demonstrated a 20% reduction in lung cancer mortality. The aim of tihs study is to establish the China National lung cancer screening guidelines for clinical practice. Methods The China lung cancer early detection and treatment expert group (CLCEDTEG) established the China National Lung Cancer Screening Guideline with multidisciplinary representation including 4 thoracic surgeons, 4 thoracic radiologists, 2 medical oncologists, 2 pulmonologists, 2 pathologist, and 2 epidemiologist. Members have engaged in interdisciplinary collaborations regarding lung cancer screening and clinical care of patients with at risk for lung cancer. The expert group reviewed the literature, including screening trials in the United States and Europe and China, and discussed local best clinical practices in the China. A consensus-based guidelines, China National Lung Cancer Screening Guideline (CNLCSG), was recommended by CLCEDTEG appointed by the National Health and Family Planning Commission, based on results of the National Lung Screening Trial, systematic review of evidence related to LDCT screening, and protocol of lung cancer screening program conducted in rural China. Results Annual lung cancer screening with LDCT is recommended for high risk individuals aged 50-74 years who have at least a 20 pack-year smoking history and who currently smoke or have quit within the past five years. Individualized decision making should be conducted before LDCT screening. LDCT screening also represents an opportunity to educate patients as to the health risks of smoking; thus, education should be integrated into the screening process in order to assist smoking cessation. Conclusion A lung cancer screening guideline is recommended for the high-risk population in China. Additional research , including LDCT combined with biomarkers, is needed to optimize the approach to low-dose CT screening in the future.

Within weeks of New Orleans's first ordinance prohibiting marijuana in 1923, police raids rounded up alleged users and peddlers on the streets, in houses, restaurants, and soft drink stands. Smokers were dubbed "muggleheads"—drawing on a vernacular term for marijuana. In this article, Adam R. Rathge examines the rise in local commentary on the dangers of marijuana and utilizes contemporary reporting from the Times-Picayune between 1920­ and 1930 to reveal the spatial and demographic makeup of the city's earliest marijuana users. "Mapping the Muggleheads" challenges existing interpretations of marijuana prohibition in the United States with new evidence from one of the first and most influential markets for marijuana in the nation.

Mark Nunes considers Roger May's Looking at Appalachia, a crowdsourced photography archive of spaces, places, and people in Appalachia, drawn from the work of many photographers of the region. As this online project reproduces and challenges tropes of Appalachian photography, Nunes describes how it encourages openness to documenting and delimiting the boundaries of Appalachian representation.

This paper is about branding goods and services and viewing China’s reference to OBOR, a new regional trade initiative, as the “accidental” branding of its efforts to institute an entirely new model of development in various places along the ancient Silk Road, as well as a number of places that fall under Chinese contemporary rise to dominance in Asia. President Xi’s use of the Silk Road was meant to generate nostalgia about a perceived favorable time in Chinese history, using it to encourage enthusiasm about China’s new efforts to “share or sell” its expertise and heavy industrial production, such as infrastructure, to developing areas. However, in a very short time Xi’s “One Belt, One Road” policy, referred to by its initials — OBOR, began to exhibit most if not all, the characteristics of a “Brand” name for goods and services.OBOR elicited positive comments from national political leaders, all of whom were potential OBOR consumers. In short order, OBOR has attracted attention, interest, responses and offers of cooperation not only from Eurasian leaders but also from leaders in Africa, Europe, Asia and most recently in South America. Strengthening OBOR as a brand can help China to enhance the value of its OBOR-related goods and services internationally and eventually lead to China’s ultimate ascendance as a dominant World economic and political Power.It is interesting to note that a new Silk Road initiative was considered by the US Department of State in 2011 in an attempt to promote integration in trade and economy between Afghanistan, Central Asia, Pakistan, and India, a North-South silk road “as a compliment to the East-West connection across Eurasia” (US State Department 2015). As noted by in a Council on Foreign Relations report by McBride (2015): «It remains to be seen if the United States and China will clash over their competing plans for developing resources in Central Asia’s Turkmenistan, creating infrastructure in Pakistan, or winning political influence with local governments throughout Asia».

The 1960s and 1970s were an important time in the history of legal education in India, when the legal aid movement and various legal aid committees’ reports started to draw attention to the importance of experiential learning, or learning on the job, in legal education. The main aim of involving law students in the national legal aid movement was to make them feel more responsible for the considerable part of the Indian population who, because of their socio-economic status, couldn’t access justice. The history of how India’s clinical programs were introduced has a lot in common with the history of clinical programs in other parts of the world. There was a desire to create a pool of lawyers, who would serve as soldiers in the fight for social justice for underprivileged groups in the country. While some prestigious universities started their clinical programs in the 1970s, most of the regulators of legal education took a long time to include clinical papers in the curriculum. In 1997 the Bar Council of India introduced four practical papers in the curriculum. The spirit of public service, and the widespread poverty in a country, has always been central to the push for clinical programs everywhere. But in India, the legal aid committees’ and other statutory bodies’ reports calling for clinical programs to support social justice, were always ignored. The National Knowledge Commission’s working group on legal education specifically mentioned the need to introduce students to issues relating to poverty, social change and social exclusion, through clinical legal education. After the introductory section, the second section discusses the introduction of clinical programs with their roots in the search for social justice in the United States and India. The third section discusses the continuous deliberation by various bodies, commissions and committees about the need to introduce clinical programs with a social justice perspective in India. The fourth section discusses the social justice-based clinical programs in China and South Africa. This section tries to highlight some of the clinical models focused on serving underprivileged groups, that have been introduced and implemented in these two countries and which ~ after local modifications ~ could serve as a template for programs in Indian law schools. The fifth section tries to search for clinical models best suited to India with reference to clinical programs in China and South Africa. Several examples of clinical activities in a few Indian law schools have been highlighted in this chapter to explain these models’ effectiveness and suitability for Indian circumstances. The sixth section sets out some suggestions for law schools and stakeholders of legal education in India as to how to further the country’s social justice mission of clinical legal education.
