In the 1920s, eugenicists adapted public health contests to create "Fitter Family for Future Firesides" contests. Designed by Mary T. Watts and Dr. Florence Sherbon, these contests were deliberately staged at agricultural fairs. These contests encouraged families to re-imagine their histories as pedigrees subject to scientific analysis and control, while appealing to a deeply rooted sense of nostalgia for the rural family as the nation became increasingly urban, as rural children left farms, and as the culture of the Roaring Twenties challenged "traditional values". As such, the fitter family contests fused nostalgia for the farm family with a modernist promise of scientific control. 相似文献

Teen employment is a very important socioeconomic phenomenon because of its consequences on human capital formation. We assess the relation between teen employment and poverty, education, and unemployment in the city of Rosario, using information from the 2010 Argentina Census disaggregated at census block level. We use two different spatial models: The spatial lag model (SLM) and a linear regression model with the spatial component filtered (filtering model, FM). Given the nature of the variables employed, multicollinearity is an issue. One of the techniques proposed in the literature to deal with multicollinearity problems is principal component regression (PCR). We develop an adaptation of such methodology to be used in the SLM. Both models are estimated using their traditional methodologies (instrumental variables for the SLM and OLS for the FM) and using PCR. Although results are similar between the two models, depending on the methodology used in the estimations they differ greatly. Under traditional methodologies estimations show high variability, instability, and contradictory outcomes, but under PCR, results behave according to the literature. 相似文献

This paper focuses on cooperation among organizations in a common‐pool resource (CPR) problem situation. Cooperation is particularly challenging in settings where resource degradation is produced by a variety of different sectors and parts of the population; and where the problem, as well as public responsibilities, transcend borders and jurisdictions. Focusing on transboundary water quality management in the Rhine catchment area, we ask: What drives two actors in a CPR problem situation to cooperate with each other? We argue that the degree of threat to a CPR is an important driver for collective action, and focus on actors’ exposure to and perception of a threat to a CPR. Furthermore, we rely on applications of the ecology of games framework (EGF), taking into account the larger institutional context of CPR management. This allows us to test whether actors’ participation in forums, such as regional and international water body associations, helps to overcome the CPR problem by further enhancing interactions among actors. Based on survey data and applying advanced network statistics (exponential random graph models [ERGM]), we conclude that although problem exposure is one factor that enhances joint cooperation, participation in forums plays an even bigger role for cooperation in a CPR problem setting. Our study contributes to research on cooperation in CPR problem settings, highlights the need to more systematically include the effects that CPR problems have on actors when analyzing CPR problem settings, and stresses the function of forums as triggers for cooperation in CPR problem situations. 相似文献

The practice and profession of evaluation is continually evolving. From its early origin in the Great Society years of the 1960s, through its golden years of the 1970s, its transformation under the fiscal conservatism of the Reagan era in the 1980s, and in its maturation during the performance and results era of the 1990s, the field of evaluation continues to evolve in response to broader trends in society. This article examines recent developments and trends in the practice and profession of evaluation. Structured around the evaluation theory tree, the presentation of these developments elaborates on the three main branches of evaluation: methods, use, and valuing. The concluding discussion briefly addresses the central role of evaluation—and other types of knowledge production—in providing actionable evidence for use in public policy and program decision making. 相似文献

ABSTRACTIn recent years, both the fields of literature and science and visual culture of science have addressed the importance of different visual and literary elements and their roles in establishing meaning and communication in science. In this article, I explore how visual and textual elements work to establish a narrative of plants in Erasmus Darwin’s The Botanic Garden (1791) and in Alexander von Humboldt’s Essai sur la géographie des plantes (1804). These two scientists employed literary and visual elements in order to construct their visions of the nature of plants in a time when the ideals of Enlightenment science gave way to a more holistic view of integrating the sciences and the arts. I, therefore, also discuss the analytical approach of integrated readings between the literary and visual elements of science. 相似文献

Artifacts made from sinistral (left-handed) whelk shells are commonly found at inland archaeological sites in eastern North America. Past attempts to source the coast of origin of these marine shells based on chemical analyses have provided tentative results. A knowledge of sinistral whelk natural history is essential before attempting shell sourcing studies. The common occurrence of sinistral whelks in the Gulf of Mexico and their uncommon occurrence along both the South Atlantic and Mid-Atlantic bights are documented. Critical biogeographical and morphological information is presented, as well as a new method of sourcing artifacts based on spire-angle measurements. Sinistral whelk artifacts from Spiro, East St. Louis, and Cahokia probably came from the eastern Gulf of Mexico. 相似文献
