A Vermont Romance Turns One Hundred: Vermont\u27s Earliest Surviving Photoplay
In 2016, a hundred-year-old film spent the year touring the northern half of Vermont, drawing audiences to refurbished opera houses and picture palaces. But the picture being celebrated for its centenary year was not D. W. Griffith\u27s Intolerance or Lois Weber\u27s Shoes, two of the best-known films made in 1916. Instead, Vermonters were watching what they believed to be the first feature film made in their state, the fetchingly titled photoplay A Vermont Romance.
But A Vermont Romance is not a conventional feature picture. None of the people who appeared in the film had previous movie acting experience, and to our knowledge, none of them appeared in another film. The picture was not made by an upstart local production company hoping to enter the lucrative business of moviemaking. Instead, it was sponsored by a newspaper, the Vermont Advance, which in turn was established to promote a political organization, the Vermont Progressive Party. To complicate matters further, the film was not made by a Vermonter. Instead, it was shot by an English cameraman living in New York and a salesman and self-proclaimed movie director from Cleveland. While the film was seen widely in Vermont, which was the intent of its sponsor, it was not distributed out of state. Instead, it was celebrated at the time as one of the first statewide contest films and, after Photoplay magazine\u27s The Beauty and Brains contest, held the same year, the biggest contest of its type. Participants competed to win parts in the production, with forty regional winners plus two stars, who received the most votes statewide. One entered the contest by buying newspapers and newspaper subscriptions, or by convincing others to do the same.
Although the paper claimed the contest a success, it was not successful enough to save the Vermont Advance, which folded within a year of the film\u27s debut. The Vermont Progressive Party did not last much longer either. Not surprisingly, none of the picture\u27s stars was able to parlay their screen debuts into an acting career. But the film itself survived, even though hundreds of nationally released movies made that year are lost, most likely destroyed by motion picture companies uninterested in keeping copies of their product.1
In this article, we discuss A Vermont Romance as two motion pictures. The first motion picture, made in 1916 as a contest film, is a significant example of how the cinema came to reflect and project ideas about social status, celebrity, and identity in the 1910s, when classical Hollywood cinema itself was being formed. The second motion picture, discovered by local historians in 1964, is an example of how popular ideas about what cinema was informs how old movies are received and reproduced in contemporary culture.2 For us, the story of A Vermont Romance is not a singular history of the film\u27s production, exhibition, and discovery but rather a dual history, one in [End Page 98] which the rediscovery of a film can be a transformative act, bringing a new significance to a work that was previously unknown to scholars, archivists, and popular audiences alike. For this reason, the story of the two Vermont Romance films provides a productive vantage point from which to think about the use and reuse of archival moving images in public history. With the recent success of Bill Morrison\u27s Dawson City: Frozen Time (2016) and Peter Jackson\u27s They Shall Not Grow Old (2018), both of which make use of film footage from the 1910s, we anticipate that public historians, curators, archivists, and programmers in museums, libraries, and archives will increasingly turn to film as a way to fill the gap between past and present. The generations of local historians and archivists who worked to make A Vermont Romance better known in their state present a unique case study of how the process of discovery, preservation, and representation can alter the perception of an archival film
Longitudinal characterization of HIV-1 pol-gene in treatment-naïve men-who-have-sex-with-men from acute to chronic infection stages
HIV-1 is characterized by its ability to mutate and recombine even at polymerase (pol) gene. However, pol-gene diversity is limited due to functional constraints. The aim of this study was to characterize longitudinally, by next-generation sequencing (NGS), HIV-1 variants based on pol-gene sequences, at intra- and inter-host level, from acute/early to chronic stages of infection, in the absence of antiretroviral therapy. Ten men who have sex with men (MSM) were recruited during primary infection and yearly followed for five years. Even after a maximum of a five-year follow-up period, the phylogenetic analysis of HIV-1 pol-gene sequences showed a host-defined structured pattern, with a predominance of purifying selection forces during the follow-up. MSM had been acutely infected by different HIV-1 variants mainly ascribed to pure subtype B, or BF recombinant variants and showed different genetic mosaicism patterns that last until the chronic stage, representing a major challenge for prevention strategies.Fil: Cevallos, Cintia Gisela.

Phylogeography of Japanese encephalitis virus:genotype is associated with climate
The circulation of vector-borne zoonotic viruses is largely determined by the overlap in the geographical distributions of virus-competent vectors and reservoir hosts. What is less clear are the factors influencing the distribution of virus-specific lineages. Japanese encephalitis virus (JEV) is the most important etiologic agent of epidemic encephalitis worldwide, and is primarily maintained between vertebrate reservoir hosts (avian and swine) and culicine mosquitoes. There are five genotypes of JEV: GI-V. In recent years, GI has displaced GIII as the dominant JEV genotype and GV has re-emerged after almost 60 years of undetected virus circulation. JEV is found throughout most of Asia, extending from maritime Siberia in the north to Australia in the south, and as far as Pakistan to the west and Saipan to the east. Transmission of JEV in temperate zones is epidemic with the majority of cases occurring in summer months, while transmission in tropical zones is endemic and occurs year-round at lower rates. To test the hypothesis that viruses circulating in these two geographical zones are genetically distinct, we applied Bayesian phylogeographic, categorical data analysis and phylogeny-trait association test techniques to the largest JEV dataset compiled to date, representing the envelope (E) gene of 487 isolates collected from 12 countries over 75 years. We demonstrated that GIII and the recently emerged GI-b are temperate genotypes likely maintained year-round in northern latitudes, while GI-a and GII are tropical genotypes likely maintained primarily through mosquito-avian and mosquito-swine transmission cycles. This study represents a new paradigm directly linking viral molecular evolution and climate
Modeling dimethylsulphide production in the upper ocean
Dimethylsulphide (DMS) is produced by upper ocean ecosystems and emitted to the atmosphere, where it may have an important role in climate regulation. Several attempts to quantify the role of DMS in climate change have been undertaken in modeling studies. We examine a model of biogenic DMS production and describe its endogenous dynamics and sensitivities. We extend the model to develop a one-dimensional version that more accurately resolves the important processes of the mixed layer in determining the ecosystem dynamics. Comparisons of the results of the one-dimensional model with an empirical relationship that describes the global distribution of DMS, and also with vertical profiles of DMS in the upper ocean measured at the Bermuda Atlantic Time Series, suggest that the model represents the interaction between the biological and physical processes well on local and global scales. Our analysis of the model confirms its veracity and provides insights into the important processes determining DMS concentration in the oceans
High Prevalence of Antibiotic-Resistant Mycoplasma genitalium in Nongonococcal Urethritis: The Need for Routine Testing and the Inadequacy of Current Treatment Options.
Background. Empirical antibiotic therapy for nongonococcal urethritis (NGU) and cervicitis is aimed at Chlamydia trachomatis, but Mycoplasma genitalium, which also commonly causes undiagnosed NGU, necessitates treatment with macrolides or fluoroquinolones rather than doxycycline, the preferred chlamydia treatment. Prevalence of M. genitalium and associated genotypic markers of macrolide and fluoroquinolone resistance among men symptomatic of urethritis were investigated. Genetic diversity of M. genitalium populations was determined to infer whether findings were applicable beyond our setting. Methods. Mycoplasma genitalium and other NGU pathogens were detected using nucleic acid amplification methods, and DNA sequencing was used to detect genotypic resistance markers of macrolide and fluoroquinolone antibiotics in 23S ribosomal RNA, gyrA, gyrB, and parC genes. MG191 single-nucleotide polymorphism typing and MG309 variable number tandem analysis were combined to assign a dual locus sequence type (DLST) to each positive sample. Results. Among 217 men, M. genitalium prevalence was 16.7% (95% confidence interval [CI], 9.5%-24.0%) and C. trachomatis prevalence was 14.7% (95% CI, 7.8%-21.6%) in NGU cases. Nine of 22 (41%; 95% CI, 20%-62%) patients with M. genitalium were infected with DLSTs possessing genotypic macrolide resistance and 1 patient was infected with a DLST having genotypic fluoroquinolone resistance. Typing assigned M. genitalium DLSTs to 2 major clusters, broadly distributed among previously typed international strains. Genotypic macrolide resistance was spread within these 2 clusters. Conclusions. Mycoplasma genitalium is a frequent undiagnosed cause of NGU in this population with rates of macrolide resistance higher than those previously documented. Current guidelines for routine testing and empirical treatment of NGU should be modified to reduce treatment failure of NGU and the development of further resistance
Phylodynamic Reconstruction Reveals Norovirus GII.4 Epidemic Expansions and their Molecular Determinants
Noroviruses are the most common cause of viral gastroenteritis. An increase in the number of globally reported norovirus outbreaks was seen the past decade, especially for outbreaks caused by successive genogroup II genotype 4 (GII.4) variants. Whether this observed increase was due to an upswing in the number of infections, or to a surveillance artifact caused by heightened awareness and concomitant improved reporting, remained unclear. Therefore, we set out to study the population structure and changes thereof of GII.4 strains detected through systematic outbreak surveillance since the early 1990s. We collected 1383 partial polymerase and 194 full capsid GII.4 sequences. A Bayesian MCMC coalescent analysis revealed an increase in the number of GII.4 infections during the last decade. The GII.4 strains included in our analyses evolved at a rate of 4.3–9.0×10−3 mutations per site per year, and share a most recent common ancestor in the early 1980s. Determinants of adaptation in the capsid protein were studied using different maximum likelihood approaches to identify sites subject to diversifying or directional selection and sites that co-evolved. While a number of the computationally determined adaptively evolving sites were on the surface of the capsid and possible subject to immune selection, we also detected sites that were subject to constrained or compensatory evolution due to secondary RNA structures, relevant in virus-replication. We highlight codons that may prove useful in identifying emerging novel variants, and, using these, indicate that the novel 2008 variant is more likely to cause a future epidemic than the 2007 variant. While norovirus infections are generally mild and self-limiting, more severe outcomes of infection frequently occur in elderly and immunocompromized people, and no treatment is available. The observed pattern of continually emerging novel variants of GII.4, causing elevated numbers of infections, is therefore a cause for concern

High Prevalence of Multidrug-Tolerant Bacteria and Associated Antimicrobial Resistance Genes Isolated from Ornamental Fish and Their Carriage Water
Background: Antimicrobials are used to directly control bacterial infections in pet (ornamental) fish and are routinely added to the water these fish are shipped in to suppress the growth of potential pathogens during transport. Methodology/Principal Findings: To assess the potential effects of this sustained selection pressure, 127 Aeromonas spp. isolated from warm and cold water ornamental fish species were screened for tolerance to 34 antimicrobials. Representative isolates were also examined for the presence of 54 resistance genes by a combination of miniaturized microarray and conventional PCR. Forty-seven of 94 Aeromonas spp. isolates recovered from tropical ornamental fish and their carriage water were tolerant to >= 15 antibiotics, representing seven or more different classes of antimicrobial. The quinolone and fluoroquinolone resistance gene, qnrS2, was detected at high frequency (37% tested recent isolates were positive by PCR). Class 1 integrons, IncA/C broad host range plasmids and a range of other antibiotic resistance genes, including floR, blaTEM21, tet(A), tet(D), tet(E), qacE2, sul1, and a number of different dihydrofolate reductase and aminoglycoside transferase coding genes were also detected in carriage water samples and bacterial isolates. Conclusions: These data suggest that ornamental fish and their carriage water act as a reservoir for both multi-resistant bacteria and resistance genes
Predicting asthma-related crisis events using routine electronic healthcare data
Background There is no published algorithm predicting asthma crisis events (accident and emergency [A&E] attendance, hospitalisation, or death) using routinely available electronic health record (EHR) data. Aim To develop an algorithm to identify individuals at high risk of an asthma crisis event. Design and setting Database analysis from primary care EHRs of people with asthma across England and Scotland. Method Multivariable logistic regression was applied to a dataset of 61 861 people with asthma from England and Scotland using the Clinical Practice Research Datalink. External validation was performed using the Secure Anonymised Information Linkage Databank of 174 240 patients from Wales. Outcomes were ≥1 hospitalisation (development dataset) and asthma-related hospitalisation, A&E attendance, or death (validation dataset) within a 12-month period. Results Risk factors for asthma-related crisis events included previous hospitalisation, older age, underweight, smoking, and blood eosinophilia. The prediction algorithm had acceptable predictive ability with a receiver operating characteristic of 0.71 (95% confidence interval [CI] = 0.70 to 0.72) in the validation dataset. Using a cut-point based on the 7% of the population at greatest risk results in a positive predictive value of 5.7% (95% CI = 5.3% to 6.1%) and a negative predictive value of 98.9% (95% CI = 98.9% to 99.0%), with sensitivity of 28.5% (95% CI = 26.7% to 30.3%) and specificity of 93.3% (95% CI = 93.2% to 93.4%); those individuals had an event risk of 6.0% compared with 1.1% for the remaining population. In total, 18 people would need to be followed to identify one admission. Conclusion This externally validated algorithm has acceptable predictive ability for identifying patients at high risk of asthma-related crisis events and excluding those not at high risk
Between a rock and a hard place? Navigating domestic and international expectations on German foreign policy
This article takes stock of German foreign policy during Angela Merkel's third term in office (2013–17). It argues that the longer-term significance of Germany's foreign policy during this period is twofold. First, the Merkel government was confronted with multiple European and international crises which worked as a magnifying glass for the growing international expectations on Germany to become more actively engaged on the international stage. Second, the tenure of the Grand Coalition saw a significant shift in the German domestic foreign policy discourse that was marked by a concerted effort of leading decision-makers to make the case for Germany to accept greater international responsibilities. This emerging consensus among foreign policy elites expresses a changed self-conception of German foreign policy which, however, continues to be viewed with scepticism in the broader public. Informed by such a broad two-level perspective that focuses on the interplay between international and domestic expectations on German foreign policy, the article explores the record of the Grand Coalition in the main international crises it had to engage with. It suggests that the Merkel government was better able to live up to its own aspirations in two-level contexts which left it with greater domestic room for manoeuvre
