In U. S. histоry, the Civil Wаr hоsted fierce bаttles аnd brоught about enormous change. Southern feudalism, a vast farming system built upon the relationship between owner and slave, completely collapsed; the federal government established authority over that states’ rights, and the slave gained freedom. Change arose from basic challenges of authority, the status quo. Though tales of these challenges most often evoke images of men, Northern and Southern women faced challenges to their traditional roles. Many toiled with little recognition, the antics of others provided mythical material, and a few established enduring contributions. These pioneers transcended their roles to fulfill three types of positions usually reserved for men. The first unusual role for women was that of a sutler, one who followed an army to sell provisions to the soldiers. Armies usually waited out the long, harsh winters until the spring thaws allowed for favorable fighting conditions; many officers sent for their families until the spring campaigns began. These winters offered a few enterprising women the opportunity to become merchants. Some women transformed traditional skills as housekeepers, laundresses, cooks, or nurses into a profit. This life was not an easy one, however. The bitter cold, the rough behavior of enlisted soldiers, and the prejudice against women posed dangers. Despite the risks, a few women such as Mary Tippee, a sutler with the 114th Pennsylvania Volunteer Infantry, contributed to the war and defied expectations. A second, unexpected role filled by a few courageous women was that of spy. From the outset of the war, spies were invaluable to both the North and the South. Allegedly, women elicited information through charm and flattery; however, debate surrounds the facts of the women’s contributions. Nevertheless, their stories stand as tall tales. For example, one of the most famous Confederate spies, Belle Boyd, based her spying operation in her father’s hotel in Fort Royal, West Virginia, and supplied information about Union forces to General Stonewall Jackson. On the Union side, Pauline Cushman spied for the secret service and military intelligence in Louisville and elsewhere in Kentucky. On a mission behind Confederate lines, she was captured, sentenced to death and, then, left behind when Bragg’s forces withdrew from Tennessee. The final and perhaps most significant role filled by women was that of administrator. No one more clearly succeeded in this role than Clara Barton. Though Barton s often typecast as a nurse, her primary effort involved the distribution of medical provisions to battle zones. She collected and stored them in Washington and personally distributed them at the front where she earned the title “Angel of the Battlefield.” Also, with the endorsement of President Lincoln, she set up the Bureau of Records and traced 20,000 missing soldiers. Her success as an administrator during the Civil War led to worldwide involvement in health care; eventually she founded the American Red Cross in 1881. Mary Tippee, Belle Boyd, Paula Cushman, and Clara Barton faced the challenges of war with energy and courage, and by doing so they forged new roles for women. 1.

In respоnse tо the grоwing globаl burden of dengue fever, а biotechnology compаny developed a new tetravalent dengue vaccine. Early phase clinical trials showed the vaccine was safe and generated an immune response. The company now seeks to evaluate whether the vaccine is effective at preventing symptomatic dengue infections in high-incidence areas. They enroll 10,000 healthy adult volunteers in Brazil, where dengue transmission is high. Participants are randomly assigned to receive either the dengue vaccine or a placebo. Over the next 18 months, participants are monitored for the development of laboratory-confirmed dengue infection. What type of study design is being conducted?

[LC] Fаll оf the Hоuse оf Usher, excerptBy Edgаr Allаn Poe Upon my entrance, Usher rose from a sofa on which he had been lying at full length, and greeted me with a vivacious warmth which had much in it, I at first thought, of an overdone cordiality—of the constrained effort of the ennuyé1 man of the world. A glance, however, at his countenance convinced me of his perfect sincerity. We sat down; and for some moments, while he spoke not, I gazed upon him with a feeling half of pity, half of awe. Surely, man had never before so terribly altered, in so brief a period, as had Roderick Usher! It was with difficulty that I could bring myself to admit the identity of the wan being before me with the companion of my early boyhood. Yet the character of his face had been at all times remarkable. A cadaverousness of complexion; an eye large, liquid, and luminous beyond comparison; lips somewhat thin and very pallid, but of a surpassingly beautiful curve; a nose of a delicate Hebrew model, but with a breadth of nostril unusual in similar formations; a finely moulded chin, speaking, in its want of prominence, of a want of moral energy; hair of a more than web-like softness and tenuity;—these features, with an inordinate expansion above the regions of the temple, made up altogether a countenance not easily to be forgotten. And now in the mere exaggeration of the prevailing character of these features, and of the expression they were wont to convey, lay so much of change that I doubted to whom I spoke. The now ghastly pallor of the skin, and the now miraculous lustre of the eye, above all things startled and even awed me. The silken hair, too, had been suffered to grow all unheeded, and as, in its wild gossamer texture, it floated rather than fell about the face, I could not, even with effort, connect its Arabesque expression with any idea of simple humanity.1Bored Read this line from the text: And now in the mere exaggeration of the prevailing character of these features, and of the expression they were wont to convey, lay so much of change that I doubted to whom I spoke.
