本文从话语理论这一视角出发,考察新闻源对新闻话语的生成所产生的影响,认为在许多情况下,记者虽然是新闻话语的写作者,但他并非是话语的主体,他只不过是充当了编码者和代言者的角色,权威的新闻源才真正是新闻话语中说话的人。 相似文献

Search facilitated with agglomerative hierarchical clustering methods was studied in a collection of Finnish newspaper articles
(N = 53,893). To allow quick experiments, clustering was applied to a sample (N = 5,000) that was reduced with principal components analysis. The dendrograms were heuristically cut to find an optimal partition,
whose clusters were compared with each of the 30 queries to retrieve the best-matching cluster. The four-level relevance assessment
was collapsed into a binary one by (A) considering all the relevant and (B) only the highly relevant documents relevant, respectively.
Single linkage (SL) was the worst method. It created many tiny clusters, and, consequently, searches enabled with it had high
precision and low recall. The complete linkage (CL), average linkage (AL), and Ward's methods (WM) returned reasonably-sized
clusters typically of 18–32 documents. Their recall (A: 27–52%, B: 50–82%) and precision (A: 83–90%, B: 18–21%) was higher
than and comparable to those of the SL clusters, respectively. The AL and WM clustering had 1–8% better effectiveness than
nearest neighbor searching (NN), and SL and CL were 1–9% less efficient that NN. However, the differences were statistically
insignificant. When evaluated with the liberal assessment A, the results suggest that the AL and WM clustering offer better
retrieval ability than NN. Assessment B renders the AL and WM clustering better than NN, when recall is considered more important
than precision. The results imply that collections in the highly inflectional and agglutinative languages, such as Finnish,
may be clustered as the collections in English, provided that documents are appropriately preprocessed. 相似文献

Curvatures are important geometric attributes of surfaces. There are many applications that require as a first step the accurate estimation of curvatures at arbitrary vertices on a triangulated surface. Chen and Schmitt (1992) and Taubin (1995)presented two simple methods to estimate principal curvatures. They used circular arcs to approximate the normal curvature. We find this may cause large error in some cases. In this paper, we describe a more accurate method to estimate the normal curvature,and present a novel algorithm to estimate principal curvatures by simplifying the Chen and Schmitt's method. Some comparison results are also shown in this paper. 相似文献

This paper follows on from the authors’ previous research into minimal Black teacher representation in Liverpool schools [Boyle, B., and M. Charles. 2010. “Tightening the Shackles: The Continued Invisibility of Liverpool's British African Caribbean Teachers.” Journal of Black Studies 42 (3): 427–435]. It is based on a re-examination of their findings of Liverpool's Black teachers’ historic institutionalised invisibility [Swann Report. 1985. Education for All. Report of the Committee of the Enquiry into the Education of Children from Ethnic Minority Groups. London: Her Majesty's Stationery Office.] and an interrogation of the situation as revealed by the 2015 data. The article uses as its evidence base, questionnaire responses and data from a sample of interviews with the current 18 Black teachers. Despite the voices of Black teachers being marginalised and even less likely to be heard, it is vital that the pedagogies of Black teachers contribute to a ‘dismantling of binaries and hierarchies that privilege Eurocentric paradigms of teaching’ [Escayg, K. 2010. “Diverse Classrooms, Diverse Teachers: Representing Cultural Diversity in the Teaching Profession and Implications for Pre-Service Admissions.” Canadian Journal for new Scholars in Education 3 (2): 1–8, 4]. 相似文献

AbstractMentoring undergraduate students in research is both rewarding and challenging. In this paper we present how we established a summer Research Experience for Undergraduates (REU) program in the mathematical sciences at Michigan State University. A goal of our REU is to include students who are at an early stage of their study of mathematics. We share our experiences in recruiting students, designing research projects, and mentoring our participants. We discuss the challenges we faced and the solutions we found while working with a diverse group of undergraduate students from across the nation. 相似文献

在知识经济时代,人才是企业最重要的战略资源.人力资源管理的核心,就是对人才的“选、育、用、留“,在这四个环节中,选拔人才是基础,只有人才选好了,才会有后来一系列的人力资源管理.面试是人力资源管理领域中应用最普遍的一种测评方法,它不仅可以评价出被试的学识水平,还能评价出被试者的能力、才智及个性心理特征等,因此,面试是企业在人员招聘中广泛使用的测评手段. 相似文献
