Tables in documents are a widely-available and rich source of information, but not yet well-utilised computationally because of the difficulty in automatically extracting their structure and data content. There has been a plethora of systems proposed to solve the problem, but current methods present low usability and accuracy and lack precision in detecting data from diverse layouts. We propose a component-based design and implementation of table processing concepts which can offer flexibility and re-usability as well as high performance on a wide range of table types. In this paper, we describe a system named TEXUS which is a fully automated table processing system that takes a PDF document and detects tables in a layout independent manner. We introduce TEXUS’s own table processing specific document model and the two-phased processing pipeline design. Through an extensive evaluation on a dataset comprised of complex financial tables, we show the performance of the system on different table types. 相似文献

ABSTRACTThe purpose of this article is to explore how pedagogical visions inform our work as former classroom teachers and current teacher educators in rural and urban regions of the United States. Specifically, we explore the instructional decisions we make as we work to meet these visions in higher education. Teacher educators are charged with the task of fostering visionary teachers in today’s highly challenging educational landscape. We pose the question: How can teacher educators foster visionary beginning teachers without an examination of their visions for their practice? Using a self-study design, we examine the intersections of our pedagogical visions for teaching and the instructional actions we take to work toward our visions in higher education. Findings highlight specific instructional practices and strategies used to enact visions while providing a critical discussion of the lens of visioning within self-study research. 相似文献

Research on social protest movements raises many complicated methodological issues. This article systematically explains the methodological quandaries the authors confronted when studying demonstrations and online and offline activism by ethnic Turks in Germany, Belgium, and the Netherlands in support of the Gezi Park protesters in Turkey. It explains how participants were recruited and surveyed in this complex and extremely sensitive environment. It offers lessons learned that can be applied to other studies involving surveys of ethnic minorities engaged in social protest movements. More generally, they may also apply to surveys of any vulnerable population about sensitive issues. 相似文献

As the demand for schools to become more effective and efficient learning communities increases, the need for principals to cultivate broad‐based, skilful participation in the work of leadership is essential. It is important for educational leaders to recognise the significance of their role in technology implementation and utilisation. They should be proficient in the use of technology and then provide leadership in the use of technology for administrative, instructional, and learning functions. Relatively few studies have empirically examined the level of computer use by principals, their perceived computer competence and their leadership style. This paper will report on these issues from an initial analysis of baseline data gathered from 30 secondary school principals in Tehran, a large province in Iran. Findings indicate that school principals spent a few times a week working on their computers and they had moderate levels of information technology competency. This paper also suggests that transformational leadership can help school leaders increase successful use of technology in schools. Hence, policy makers must design professional development programmes, such as leadership studies, in order to teach the components of transformational leadership: idealised influence, inspirational motivation, intellectual stimulation and individual consideration to future administrators. 相似文献

In this study, we examined framing in the U.S. and Chinese press coverage of the Fourth United Nations Conference on Women and the Non-Governmental Organizations Forum in Beijing in 1995. This study had 2 objectives: (a) to systematically assess the coverage of this global feminist event and the extent to which its critical areas of concern were communicated to the public, and (b) to illuminate the dynamics of framing in a comparative context and contribute to its further theoretical development. Employing quantitative and qualitative methods, this study found evidence of the operation of an anticommunist and an antifeminist frame in the U.S. coverage. Under the influence of dominant ideology, the U.S. coverage of the conference focused considerably on an extended criticism of China as a communist nation. The goals of the global feminist movement and their critical areas of concern appeared to hold far less immediacy and salience for the U.S. press than the need to assert dominant U.S. values. On the other hand, under the influence of communist ideology, the Chinese coverage reflected a proequality frame and a strong focus on the critical issues of concern to the global feminist movement. Despite the existence of a propagandistic emphasis on the country's extensive preparations as conference host as well as efforts to defend against Western criticism, nationalistic praise for China was far more subtle than originally expected. 相似文献

Cardiovascular disease, as the leading cause of patient death with chronic kidney disease, could be predicted by carotid atherosclerosis. The aim of the present study was to evaluate a possible relationship between serum soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and Vitamin D levels with mean right/left carotid intima-media thickness (cIMT), in the hemodialysis (HD) patients. In this cross-sectional study, serums were obtained from 50 stable chronic HD patients and 39 healthy controls. The serum levels of sTWEAK, Vitamin D, intact parathyroid hormone (iPTH) in both groups, and cIMT were determined in HD patients by standard methods. Serum levels of sTWEAK were higher [808.8 (521.6–5032.4) pg/ml vs. 664.4 (487.4–2955.8) pg/ml (p = 0.006)] and Vitamin D levels were lower [13.4 (2.5–153) ng/ml vs. 27.8 (18.4–59.0) ng/ml (p = 0.001)] in the hemodialysis patients than in the healthy control. No important correlation was found between sTWEAK Vitamin D levels (r = 0.010/p = 0.946), and mean right(r = ?0.194/p = 0.178) and left (r = 0.061/p = 0.673) cIMT in the HD patients. Our study shows that sTWEAK levels are elevated in HD patients. This elevation has no association with the cIMT. 相似文献

Decades of theorisation and research on the teaching and learning of second-language writing have hardly created coherent theoretically profound and practically relevant understandings of writing instruction. This article discusses the possibilities and insights created by bringing personal meaningfulness into the realm of writing pedagogy. Briefly revisiting the mainstream landscape of second-language writing theory and, more specifically, addressing aspects of (im)personal academic writing and publishing, we present an overview of the notion of wor(l)d writing, which implies the intimate interconnection of writing and the writer’s individual and social identity. Recognising the role of linguistic forms, cognitive processes and socio-political situatedness of writing practices, such a perspective underscores the importance of balancing these elements and going beyond them by bringing the self of the writer into the writing practice. On this basis, we argue that language and literacy education may be enhanced by acknowledging the little-explored wonders of writing and understanding it as an act of composing and narrating the word-world of the self-other. 相似文献
