Hungarian born American chemist, George Andrew Olah was a prolific researcher. The central theme of his career was the pursuit of structure and mechanisms in chemistry, particularly focused on electron-deficient intermediates. He leaves behind a large body of work comprising almost 1500 papers and twenty books for the scientific community. Some selected works have been published in three aptly entitled volumes, Across Conventional Lines.There is no way to capture the many contributions of Olah in a short essay. For this appreciation, we have chosen to high-light some of those contributions that to our mind represent a significant advance to the state of knowledge. 相似文献

This investigation assessed the impact of situating explicit nature of science (NOS) instruction within the issues surrounding
global climate change and global warming (GCC/GW). Participants in the study were 15 preservice elementary teachers enrolled
in a science methods course. The instructional intervention included explicit NOS instruction combined with explicit GCC/GW
instruction situated within the normal elementary science methods curriculum. Participants’ conceptions of NOS and GCC/GW
were assessed with pre- and postadministrations of open-ended questionnaires and interviews. Results indicated that participants’
conceptions of NOS and GCC/GW improved over the course of the semester. Furthermore, participants were able to apply their
conceptions to decision making about socioscientific issues. The results provide support for context-based NOS instruction
in an elementary science methods course. 相似文献

ABSTRACTDo the narratives of employability constructed by higher education institutions for marketing purposes differ from the conceptualisation and/or the realisation of employability within those institutions? The study reported here drew on interviews with 16 senior academic and student support staff who were tasked with developing student employability at one of nine institutions in Australia, Canada and the UK. We employed Holmes’ conceptions of employability as possessional, positional or processual to analyse how the interviewees conceptualised employability and the presentation of employability on the institutional websites. We found that most institutions’ employability marketing narratives were inconsistent with the institutional practice reported by staff. We explain this tension in the context of two competing characterisations of higher education: a university-student transaction view; and a learning view. We emphasise the need for internal and external narratives to align and advocate the need for engagement in a constructive and critical dialogue involving all stakeholders. 相似文献

Given increasing interest in evidence-based policy, there is growing attention to how well the results from rigorous program evaluations may inform policy decisions. However, little attention has been paid to documenting the characteristics of schools or districts that participate in rigorous educational evaluations, and how they compare to potential target populations for the interventions that were evaluated. Utilizing a list of the actual districts that participated in 11 large-scale rigorous educational evaluations, we compare those districts to several different target populations of districts that could potentially be affected by policy decisions regarding the interventions under study. We find that school districts that participated in the 11 rigorous educational evaluations differ from the interventions' target populations in several ways, including size, student performance on state assessments, and location (urban/rural). These findings raise questions about whether, as currently implemented, the results from rigorous impact studies in education are likely to generalize to the larger set of school districts—and thus schools and students—of potential interest to policymakers, and how we can improve our study designs to retain strong internal validity while also enhancing external validity. 相似文献

This paper takes the grotesque as a model of subjectivity that offers compelling inroads to understanding adolescence. Bakhtin notes that the grotesque ‘seeks to grasp in its imagery the very act of becoming and growth, the eternal, incomplete, unfinished nature of being’. I argue that Carson McCullers' novel, The Member of the Wedding (1946), is largely about this ‘act of becoming’ in its heightened form, at the time of early adolescence, and I explore the ways in which puberty estranges 12‐year‐old Frankie Adam from her old body and her old self, resulting in encounters with the uncanny. 相似文献

Although much of the current educational research literature on achievement gaps has focused on core curricular areas in public schools, few have focused on racially identifiable gaps in non-core areas such as high school foreign languages. These achievement, and thus advancement, gaps often result in the under-representation of students of color in higher level foreign language classes. This can have long-range negative consequences for students, such as lacking the foreign language credits needed for admission into major universities. Thus, in this qualitative study, we researched the perceptions of teachers, counselors, and school leaders at a racially diverse urban high school in central Texas concerning the enrollment, achievement, and advancement of African American students in high school foreign language courses. The results indicate that equity traps—deficit views, racial erasure, and paralogical beliefs and behaviors—advanced over a decade ago (McKenzie &; Scheurich, 2004) are continuing and even thriving among teachers, counselors, and school leaders in public schools. These equity traps contribute to the foreign language achievement gap, resulting in diminished educational opportunities for African American students. Moreover, we propose that an additional equity trap is at play—organizational constraints—which are the structural obstacles that serve to abet and perpetuate the negative beliefs, behaviors, attitudes, and assumptions exposed in the original equity traps. We conclude this article with recommendations for policy makers and practitioners and offer direction for future research. 相似文献

After a brief discussion of the historical background, this article examines national attempts to reform the examination system in India. Reform attempts are discussed under eight categories: syllabus review and revision; increased frequency of public examinations; introduction of internal assessment; development of question banks; changeover to a grading system; semesterisation; improving the efficiency of the public examination bureaucracy, and, creation of autonomous colleges. Most of the impetus for reforming the examination system came from the availability of Western experts at very little cost to India and admiration for American and British practices among Indian higher education authorities. The failure of most of the reforms provide salutary lessons regarding educational borrowing for reform. The concluding pages discuss the theoretical issues related to the reform effort.First published inHigher Education Reform in India, eds. Philip G.

This study examined the concurrent validity of the Slosson Full‐Range Intelligence Test (S‐FRIT) by comparing S‐FRIT scores to the scores of the Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Woodcock‐Johnson Tests of Achievement–Revised (WJ‐R). Data from 123 elementary students' screening and psychological testing results were examined. Results revealed that the S‐FRIT scores were more related to overall intelligence, verbal, and math abilities than nonverbal intelligence, reading, or written language abilities. Further, it was found that 89% of the participants' S‐FRIT Full‐Range IQ scores fell within one standard deviation of their WISC‐III FSIQ scores, with an average discrepancy of 7.6 points. Discrepancies between S‐FRIT and WISC‐III scores were also examined by educational diagnostic categories and ability levels. Limitations and suggestions for future research are provided. © 2002 John Wiley & Sons, Inc. 相似文献
