    By the spring of 1777 loyalty and leadership in America had been tested both politically in congress and militarily on the battlefield for well over two years. The Continental Congress had declared independence the previous July, and General Washington’s military victories at Trenton in December 1776 and Princeton the following month stabilized wavering American patriotism after the massive loss of New York during the previous fall. Regional tensions were at a heightened state, especially in the Continental Congress. By March 1776 the Continental Army had lost their foothold on upper Canada, in large part due to the lack of material support from congress. Politicians in Philadelphia required a scapegoat for their inaction. They found one with the oldest general officer they had appointed to the position of brigadier general in 1775: David Wooster of Connecticut. On April 27, 1777, after being recommissioned as Connecticut’s senior ranking major general of militia, Wooster learned of a pending invasion of his home state. Major General Wooster, supported by Brigadier Generals Benedict Arnold and Gold Selleck Silliman, also from Connecticut, called out the militia and marched to Danbury to oppose the invaders. British troops under the command of General Tryon, the tory governor of New York, marched into Connecticut to seize a store of munitions held by the patriots in Danbury. On Tuesday morning, April 29, American troops met the British forces at the Battle of Ridgefield. As the enemy was engaged by Arnold and Silliman, Wooster’s troops attacked the rear of the retreating enemy. Wooster rallied his men forward to drive the British and loyalist forces from the field. While repositioning his men, he turned in his saddle, sword in hand, and was struck in his side by an enemy bullet and fell mortally wounded from his horse. The ball shattered Wooster’s spine. Soldiers removed the general’s scarlet sash from around his waist, unwrapped it, bore the dying officer from the field in the make-shift stretcher. On May 2, 1777, with his wife and son present, Major General David Wooster died and was quickly buried due to the proximity of the enemy still along the coast. At age sixty-seven, the oldest American general in the Revolution was dead. On June 17, 1777, the Continental Congress passed a resolution creating a committee to determine the most fitting way to honor “Brigadier Wooster.” The responsibility fell to Connecticut Governor Jonathan Trumbull, who had highly praised Wooster in a letter to General Washington on July 13, 1775, as being “held in high estimation by our Assembly, and by the officers and troops.” However, due to continued British threats followed by a second attack on the Connecticut coast in 1779, no memorial was ever erected. In 1786, the Confederation Congress officially created the Western Reserve of Connecticut in northeast Ohio, the “Firelands” as they were more commonly called. This land was made available to those in Connecticut who had lost their homes due to the devastation of the war. Wayne County was located on the southern edge of the Western Reserve and became home of many Connecticut refugees. By 1808, Wayne County had become sufficiently populated to establish an official county seat, and the veterans who resided there took the opportunity to honor the late Major General David Wooster by naming the county seat after the fallen general, who had been dead for almost thirty-two years. Yet today the question still arises: Who was David Wooster, and why should he be remembered within the annals of eighteenth-century American History? If this man was held in such “high estimation” by those in power in Connecticut throughout the 1700s, why has no one heard of him? Why has history, and the historiography of the eighteenth-century neglected him? Wooster’s experience highlighted the development and growth of American ideology throughout the 1700s that revolved around Lockean republicanism, military training, and civic leadership. His story provides new evidence which highlights the importance of eighteenth-century New England as an epicenter of political revolutionary ideology. David Wooster was a prominent leader in Connecticut throughout the 1700s, and was actively engaged in the civic, political, and military life of the colony. As historians continue to write about eighteenth-century America, as well as the Revolutionary War, David Wooster continues to evade the narrative, or at best is offered a peripheral reference. Why? By 1775 Wooster already had decades of successful military experience and was appointed the first major general of Connecticut militia before the Continental Army was even created. Yet, the historiography continues to provide only a tertiary glance at Wooster’s undeniable leadership. The focus of this dissertation will be to uncover how David Wooster shaped eighteenth-century Connecticut, and how his undivided loyalty and unwavering leadership are two characteristics that embody and define his life. As a British subject and commissioned officer in the army, his loyalty to England was unquestioned in his early years. However, as political abuses of royal authority and parliamentary government in London permeated into the colonies in North America, the seeds of political discontentment were sown, and Wooster eventually refocused his political loyalty upon his home colony of Connecticut. What would make a sixty-five-year-old merchant, justice of the peace, captain of the 51st Regiment of Foot, and naval custom officer for the port of New Haven yield his royal commission in 1775 and endanger his entire livelihood to take up arms in the republican cause of independence and liberty? The historical record of David Wooster is sparce. In 1779 British General Tryon led a raid upon New Haven and the surrounding Connecticut countryside. Wooster’s home was targeted. Many of his personal papers, including much of his correspondence, were destroyed. Thus, to recreate Wooster’s place within the historic narrative requires analysis of a limited number of surviving letters and intense research to locate additional sources within the correspondences of those who wrote to Wooster. Political journals of the colonies of Connecticut, Massachusetts, and New York provide important details, as well as the Journals of the Continental Congress. In addition, the personal papers of Connecticut Governors, Law, Fitch, Pitkin, and Trumbull illuminate the historical record where Wooster’s actions become difficult to trace. Furthermore, prominent individuals who interacted with Wooster wrote about him, such as Sir William Pepperrell, Philip Schuyler, Roger Sherman, and John Adams whose letters contain invaluable material on his life

    The James Webb Space Telescope Mission

    Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4m4m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5m6.5m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

    Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

    Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∌38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

    Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

    Get PDF
    Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional studies. To address the challenges and opportunities in this rapidly evolving field, the International Society for Extracellular Vesicles (ISEV) updates its 'Minimal Information for Studies of Extracellular Vesicles', which was first published in 2014 and then in 2018 as MISEV2014 and MISEV2018, respectively. The goal of the current document, MISEV2023, is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation and characterisation of EVs from multiple sources, including cell culture, body fluids and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, this document also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 also includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. Compiling feedback from ISEV expert task forces and more than 1000 researchers, this document conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly

    Robust estimation of bacterial cell count from optical density

    Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

    An open dataset of Plasmodium falciparum genome variation in 7,000 worldwide samples.

    MalariaGEN is a data-sharing network that enables groups around the world to work together on the genomic epidemiology of malaria. Here we describe a new release of curated genome variation data on 7,000 Plasmodium falciparum samples from MalariaGEN partner studies in 28 malaria-endemic countries. High-quality genotype calls on 3 million single nucleotide polymorphisms (SNPs) and short indels were produced using a standardised analysis pipeline. Copy number variants associated with drug resistance and structural variants that cause failure of rapid diagnostic tests were also analysed.  Almost all samples showed genetic evidence of resistance to at least one antimalarial drug, and some samples from Southeast Asia carried markers of resistance to six commonly-used drugs. Genes expressed during the mosquito stage of the parasite life-cycle are prominent among loci that show strong geographic differentiation. By continuing to enlarge this open data resource we aim to facilitate research into the evolutionary processes affecting malaria control and to accelerate development of the surveillance toolkit required for malaria elimination

    Pf7: an open dataset of Plasmodium falciparum genome variation in 20,000 worldwide samples

    We describe the MalariaGEN Pf7 data resource, the seventh release of Plasmodium falciparum genome variation data from the MalariaGEN network.  It comprises over 20,000 samples from 82 partner studies in 33 countries, including several malaria endemic regions that were previously underrepresented.  For the first time we include dried blood spot samples that were sequenced after selective whole genome amplification, necessitating new methods to genotype copy number variations.  We identify a large number of newly emerging crt mutations in parts of Southeast Asia, and show examples of heterogeneities in patterns of drug resistance within Africa and within the Indian subcontinent.  We describe the profile of variations in the C-terminal of the csp gene and relate this to the sequence used in the RTS,S and R21 malaria vaccines.  Pf7 provides high-quality data on genotype calls for 6 million SNPs and short indels, analysis of large deletions that cause failure of rapid diagnostic tests, and systematic characterisation of six major drug resistance loci, all of which can be freely downloaded from the MalariaGEN website

    Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

    A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importñncia de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

    Navy advertising: targeting Generation Z

    Get PDF
    MBA Professional ReportThis study recommends improvements for Navy advertising efficiency by examining characteristics of recruits defined as Generation Z. Data gathered from five waves of the New Recruit Survey covering September 2012 to April 2015 were separated into two groups by age, with ages 17–21 representing Generation Z recruits and those over 21 as the Other generation. Four main analysis questions centered on parental influences, social media habits, and advertisements received or viewed by the recruits. Our research found that Generation Z places a high value on parental input, suggesting that advertising directly to parents may be a viable option. The research also showed that recruits recall seeing Navy advertisements on television and on the Internet far more than on any other medium; all new recruits, on average, consume advertising media the same way across different formats; print readership (mediums such as newspaper, magazine, and book) seems to be declining over time. Further research should continue to use the New Recruit Survey and link responses to the Navy’s 3C1L Recruiting and Advertising budget.http://archive.org/details/navydvertisingta1094547825Captain, United States Marine CorpsLieutenant Commander, United States NavyApproved for public release; distribution is unlimited
