Lawrence CONTEXT: Understanding women's reasons for having abortions can inform public debate and policy regarding abortion and unwanted pregnancy. Demographic changes over the last two decades highlight the need for a reassessment of why women decide to have abortions. METHODS: In 2004, a structured survey was completed by 1,209 abortion patients at 11 large providers, and in-depth interviews were conducted with 38 women at four sites. Bivariate analyses examined differences in the reasons for abortion across subgroups, and multivariate logistic regression models assessed associations between respondent characteristics and reported reasons. RESULTS: The reasons most frequently cited were that having a child would interfere with a woman's education, work or ability to care for dependents (74%); that she could not afford a baby now (73%); and that she did not want to be a single mother or was having relationship problems (48%). Nearly four in 10 women said they had completed their childbearing, and almost one-third were not ready to have a child. Fewer than 1% said their parents' or partners' desire for them to have an abortion was the most important reason. Younger women often reported that they were unprepared for the transition to motherhood, while older women regularly cited their responsibility to dependents. CONCLUSIONS: The decision to have an abortion is typically motivated by multiple, diverse and interrelated reasons. The themes of responsibility to others and resource limitations, such as financial constraints and lack of partner support, recurred throughout the study. [source] Exploring New Frontiers: What Do Computers Contribute to Teaching Foreign Languages in Elementary School?FOREIGN LANGUAGE ANNALS, Issue 3 2002Joyce W. Nutta ABSTRACT: Two growing trends in foreign language education, the study of foreign languages in the elementary school (FLES) and the use of computer-assisted language learning (CALL), have been well researched independently but rarely in concert. This study compares the use of a print and multimedia program to teach Spanish to second through fifth graders from quantitative and qualitative perspectives. The experimental portion of the study showed that the achievement and proficiency of students using print or multimedia materials did not differ at posttest. However, a small but statistically significant difference in achievement emerged at the delayed test point in favor of the students who used the multimedia materials, although this finding is limited by participant attrition over the 13-month study. The qualitative portion of the study detected differences in language behavior, with the students who used multimedia spending more time to stop, check, and revise their language production, leading to greater precision in pronunciation and the use of larger chunks of language when repeating phrases. [source] An introduction to coil array design for parallel MRINMR IN BIOMEDICINE, Issue 3 2006Michael A. Ohliger Abstract The basic principles of radiofrequency coil array design for parallel MRI are described from both theoretical and practical perspectives. Because parallel MRI techniques rely on coil array sensitivities to provide spatial information about the sample, a careful choice of array design is essential. The concepts of coil array spatial encoding are first discussed from four qualitative perspectives. These qualitative descriptions include using coil arrays to emulate spatial harmonics, choosing coils with selective sensitivities to aliased pixels, using coil sensitivities with broad k -space reception profiles, and relying on detector coils to provide a set of generalized projections of the sample. This qualitative discussion is followed by a quantitative analysis of coil arrays, which is discussed in terms of the baseline SNR of the received images as well as the noise amplifications (g -factor) in the reconstructed data. The complications encountered during the experimental evaluation of coil array SNR are discussed, and solutions are proposed. A series of specific array designs are reviewed, with an emphasis on the general design considerations that motivate each approach. Finally, a set of special topics is discussed, which reflect issues that have become important, especially as arrays are being designed for more high-performance applications of parallel MRI. These topics include concerns about the depth penetration of arrays composed of small elements, the use of adaptive arrays for systems with limited receiver channels, the management of inductive coupling between array elements, and special considerations required at high field strengths. The fundamental limits of spatial encoding using coil arrays are discussed, with a primary emphasis on how the determination of these limits impacts the design of optimized arrays. This review is intended to provide insight into how arrays are currently used for parallel MRI and to place into context the new innovations that are to come. Copyright © 2006 John Wiley & Sons, Ltd.
