In order to understand how children's beliefs and cognitive performance vary according to development in their conceptions of effort and ability, 120 fourth and sixth graders were given the following assessments: (a) a measure of agency beliefs, defined as the extent to which persons believe they have access to certain classes of potential means, including effort, ability, powerful others, and luck; (b) a battery of intelligence test scales, including figural patterns, letter series, arithmetic, and spelling; (c) an interview designed to assess developmental levels in conceptions of effort and ability. Correlations between intelligence scores and agency beliefs for effort decreased with increasing levels of reasoning about effort and ability, but correlations between intelligence scores and agency beliefs for ability increased with increasing levels of reasoning. No such trends were found in correlations between performance and agency beliefs for luck or for unknown causes. The results are discussed in terms of the interaction between individual differences and developmental change. 相似文献

This paper addresses the evaluation of real growth forecasts made by impact studies. Intervention analysis is used to estimate the ex post impact of blockbuster exhibits on economic growth in Jackson, Mississippi (chosen because state and local governments provide regular subsidies to finance the exhibitions). Non-farm employment measures real economic growth and dummy variables capture the occurrence of the exhibitions. Univariate time series techniques identify and estimate a stationary process after filtering the data for seasonal and cyclical effects. The analysis estimates the short run impact on Jackson’s filtered employment series due to the blockbuster exhibitions as approximately 700 jobs. 相似文献

This article examines 3 papers presented before the Cincinnati Academy of Medicine by 19th-century physician Julia W. Carpenter. The article identifies 3 strategies Carpenter used to negotiate the incompatible rhetorical expectations for women and for physicians. The published records of academy discussions provide evidence for Carpenter's colleagues' reactions to each strategy, revealing the complexity of her rhetorical situation and demonstrating the complex links among rhetorical practice, professional identity, and a communicator's social position. 相似文献

This research examined the relationship between placement in a learning support college program and subsequent academic outcomes. The sample consisted of 275 entering freshmen students who were enrolled in the Learning Support reading courses in the fall of 2005. Data were collected from the Gordon College Office of Institutional Research. The data showed that of the 275 students who enrolled in a Learning Support reading course in the fall 2005 semester, 189 returned for the spring 2006 semester. Data also showed that 58% of the 275 students enrolled in Learning Support reading during fall 2005 successfully completed a basic reading intensive course upon completion of their remedial reading class. One hundred eighty seven students who had previously completed Learning Support reading enrolled (spring 2006 or later) in Introductory English 101 and 121 passed. Fifty-five students who had completed Learning Support reading enrolled (spring 2006 or later) in History 1121, Western Civilization, and 20 students passed. Six of the 205 students who completed Learning Support reading graduated Gordon College within a three-year period. The results of the present study indicate that the Learning Support Reading Program in place at Gordon College has proven to be a beneficial tool for at-risk college students. It is assumed that programs such as the Learning Support Program described here may help students build a foundation that will aid them throughout their college career. 相似文献

ABSTRACTDrawing on ethnographic observations and interviews, this paper examines the market work performed by real estate agents in a residential market. The research explores how agents are engaged in market work to sell themselves, the market and the products in order to sell houses. Agents first invest in the clients by self-presentation techniques (likeability, availability, appearance, taste). They also work to bring the clients in line with the market by making them accept the market and its hierarchies; and finally, they enable clients to conform with the market, by relying on prices as signals and taste hierarchies. They act as market devices contributing to market valuation as they are engaged in making residential choices emerge, balancing the cold reality of the market with warm relationships to foster clients' engagement in transactions. 相似文献
