Small Satellite Industrial Base Study: Foundational Findings

This report documents findings from a Small Satellite (SmallSat) Industrial Base Study conducted by The Aerospace Corporation between November 2018 and September 2019. The primary objectives of this study were a) to gain a better understanding of the SmallSat communitys technical practices, engineering approaches, requirements flow-downs, and common processes and b) identify insights and recommendations for how the government can further capitalize on the strengths and capabilities of SmallSat offerings. In the context of this study, SmallSats are understood to weigh no more than 500 kg, as described in State of the Art Small Spacecraft Technology, NASA/TP-2018- 220027, December 2018. CubeSats were excluded from this study to avoid overlap and duplication of recently completed work or other studies already under way. The team also touched on differences between traditional space-grade and the emerging mid-grade and other non-space, alternate-grade EEEE (electrical, electronic, electromechanical, electro-optical) piece part categories. Finally, the participants sought to understand the potential effects of increased use of alternate-grade parts on the traditional space-grade industrial base. The study team was keenly aware that there are missions for which non-space grade parts currently are infeasible for the foreseeable future. National security, long-duration and high-reliability missions intolerant of risk are a few examples. The team sought to identify benefits of alternative parts and approaches that can be harnessed by the government to achieve greater efficiencies and capabilities without impacting mission success

Jewish Pioneers in the Service of Christian Whiteness in the 19th-Century American West

In recent years, historians of American religion have contributed significantly to pushing back against the conception of America as a nation founded on religious freedom and characterized since its inception by a strong sense of pluralism. Although religious tolerance was one of the most essential American ideals, it was not always a reality for minority religious groups, and the religious pluralism that developed in the years after the Revolution was created by those outside of the Christian majority who had to fight to create space within it. This research has shown that over the course of American history, Jews have played a significant role in these efforts and in the creation of pluralism in America

Jewish People and Relationships with Christians in the Antebellum US

In surveys of American history, the presence of Jewish people is usually not mentioned more than twice. The first time is with the late 19th-century’s major wave of Jewish immigration, and the second is with the onset of the Second World War and the Holocaust. Although discussing the history of Jewish immigration and anti-semitism in the United States is important, these stories are not the only ones that comprise Jewish American history. Little attention is paid to the Jewish population in America during the antebellum era, yet it is clear that Jewish people were here, and their presence was only growing. What occupied their lives, thoughts, and writings during this time? What can we learn from their experiences in this era as both a significant religious minority and members of the largest population of Jewish people in America until that point? One element that was stressed in the writings of Jewish Americans during the antebellum era was their interactions with Christians. Jewish people throughout this period devoted significant space to writing about relationships with Christians, attempting not only to create those connections but to define the favorability of their terms, offering critiques when they were harmful to Jewish people and welcoming those that benefitted them. By analyzing debates between Jewish and Christian people over the validity of each’s religion, attempts by Jewish people to protect the future of Judaism in America from proselytization, and newspaper clippings that offer a glimpse into interactions between Richmond’s Jewish and Christian communities, this essay will argue that in using relationships with Christians as a means to foment respect for their faith, Jewish people made a space for themselves within a Christian majority and tested the notion of national Christian homogeneity in antebellum America

Rabbits and Hogs and Bears, Oh My! Monstrous Births and Control Over Pregnant Bodies

Monstrous birth stories occupied early modern European society between the 16th and 18th centuries. These stories depicted gruesome and fantastical births influenced by the imaginations and ill virtue of pregnant women, and the tales were the subject of much interest within the intellectual and medical community. The discussion of these births that took place among the male members of such communities were particularly revelatory of the way female bodies were viewed and controlled in early modern Europe. These conversations are evidenced in the writings of 16th and 17th-century European physicians about the power of women’s imaginations over their pregnant bodies, in the retelling of monstrous birth stories that emphasized the importance of women’s virtue, and in the case of Mary Toft herself and the physicians who attended to her. Through these sources, male medical professionals and educated men utilized monstrous births to assert their role in pregnancy, revealing their desire to exert control over women’s bodies

A vision of leadership : a reflective essay

My interest in the field of education was sparked before I entered kindergarten. My mom was a teacher and I had two high school-aged siblings planning to enter the educational field. These three individuals greatly influenced my desire to enter the educational profession. By the age of eight, I had decided that I was going to make a difference in the lives of children and to right all of the wrongs that I had heard about from various family conversations. My maturity and experiences have allowed me to reflect upon the roles of leadership

Corporate donations, the best interest of the company and the proper purpose doctrine

Corporate philanthropy is illegitimate spending by powerful corporate elite of someone else&rsquo;s money; an attempt to bypass democratic allocation of taxes; philanthropy by individuals is laudable, but not by corporations.Just as I wouldn&rsquo;t want you to implement your personal judgments by writing checks on my bank account for charities of your choice, I feel it inappropriate to write checks on your corporate &lsquo;bank account&rsquo; for the charities of my choice.<br /

Loss of the DNA methyltransferase MET1 Induces H3K9 hypermethylation at PcG target genes and redistribution of H3K27 trimethylation to transposons in Arabidopsis thaliana.

Dimethylation of histone H3 lysine 9 (H3K9m2) and trimethylation of histone H3 lysine 27 (H3K27m3) are two hallmarks of transcriptional repression in many organisms. In Arabidopsis thaliana, H3K27m3 is targeted by Polycomb Group (PcG) proteins and is associated with silent protein-coding genes, while H3K9m2 is correlated with DNA methylation and is associated with transposons and repetitive sequences. Recently, ectopic genic DNA methylation in the CHG context (where H is any base except G) has been observed in globally DNA hypomethylated mutants such as met1, but neither the nature of the hypermethylated loci nor the biological significance of this epigenetic phenomenon have been investigated. Here, we generated high-resolution, genome-wide maps of both H3K9m2 and H3K27m3 in wild-type and met1 plants, which we integrated with transcriptional data, to explore the relationships between these two marks. We found that ectopic H3K9m2 observed in met1 can be due to defects in IBM1-mediated H3K9m2 demethylation at some sites, but most importantly targets H3K27m3-marked genes, suggesting an interplay between these two silencing marks. Furthermore, H3K9m2/DNA-hypermethylation at these PcG targets in met1 is coupled with a decrease in H3K27m3 marks, whereas CG/H3K9m2 hypomethylated transposons become ectopically H3K27m3 hypermethylated. Our results bear interesting similarities with cancer cells, which show global losses of DNA methylation but ectopic hypermethylation of genes previously marked by H3K27m3
