Eve Drewelowe (1899–1988) was an American artist who attended the University of Iowa, where she received a BA in Graphic and Plastic Arts in 1923. During these early years when university art programs were being established, Drewelowe became the first person to receive an MA in art from the University of Iowa; one of the first people to receive such a degree in the United States. Drewelowe reinvented herself throughout her life and her artwork reflects a current knowledge of modern styles that emerged in the twentieth century. Drewelowe exhibited under the name Eve Drewelowe Van Ek shortly after her marriage in 1924 until the early 1950s, when she chose to resume using only her own surname. During the three intervening decades, her signature varies from one artwork to the next. In some instances, the artist later rubbed out or painted over the ‘Van Ek’ with little attempt to conceal the change, leaving a visual indicator of the artist's identity struggles. Her personal papers also reflect the challenges she faced reconciling public expectations of her role as the wife of a university dean with her profession as an artist. This essay considers the ways Drewelowe performed her identity as an artist in order to maintain her personal autonomy against the backdrop of the male dominated social and artistic world.  相似文献

There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.

User charges, which have become an important revenue enhancement device during the 1980s, have also raised a variety of counter-charges. This study examines three new mandatory Customs Service fees—for processing passengers, conveyances, and merchandise entering the United States and for special services at small airports—along with their differences and changes over time (in rate structure, exemptions, dedicated accounts, and disposition of funds). Despite support for the charges, opposition to some has arisen because of their cost to the private sector, violation of certain assumptions behind user fees, competing international obligations and policies, rival institutional interests and powers of Congress and the presidency, and changing fiscal conditions.  相似文献

Fraudulent substitution of a page within a multiple page document such as a will or business contract, the counterfeit manufacture of paper banknotes, and linking ransom or extortion notes have all been the focus of criminal investigations at one time or another. In a recent homicide investigation, document examiners were requested to compare a threatening letter received by a business partner of the deceased with paper samples seized under warrant from a suspect's house. Through a quantitative elemental analysis of the concentrations of nine elements (Na, Mg, Al, Mn, Sr, Y, Ba, La, and Ce) within the questioned and specimen documents, determined by inductively coupled plasma-mass spectrometry (ICP-MS), it was concluded that (i) the paper of the threatening letter originated from a different source to that of the paper seized from the suspect's house and (ii) all six pages of paper seized from the suspect's house originated from the same source. This discrimination of paper is presented as both a statistical t-test analysis (99.9% confidence limit) as well as construction of an elemental fingerprint for individual replicates within the questioned and specimen sample populations. This is the first reported use of the comparison of the elemental composition of document paper, determined by ICP-MS, to assist in a criminal investigation.  相似文献
