基于大规模定制的EWMAQ控制图应用研究     

赵玲玲  樊树海  吕庆文  徐文浩 《科技管理研究》2020,40(2)

对于目前的制造型企业而言,质量问题是企业在社会上发展,保持竞争力的重要影响因素。大规模定制（MC）又是现今社会较为先进的生产模式,并且大规模定制下的质量控制是其近些年研究的难点。但目前的常规控制图并不完全适用于大规模定制生产。本文旨在针对大规模定制生产模式的特点,提出以下这种应用Q统计量及指数加权移动平均控制图的联合统计制程管制的方法来监测大规模定制下产品生产过程质量的,取长补短地解决我们在目前更为先进的生产模式下监测过程质量时所研究的问题。  相似文献   

上市公司知识产权信息披露及其价值相关性研究     

刘晓雨  鲍新中 《科技管理研究》2020,(8)

财政部2018年7月颁发的《知识产权会计信息披露规定(征求意见稿)》将知识产权信息披露的规范化提上了日程。本文首先建立了知识产权信息披露指数来反映上市公司知识产权信息披露状况,并以信息技术业为例进行了实证分析。在此基础上,对知识产权信息披露指数的价值相关性进行了分析。实证研究表明：上市公司知识产权信息披露状况间存在较为明显的差异,信息披露状况对公司价值有显著性影响并呈现出正相关关系。  相似文献   

Beliefs of teachers in Italian schools concerning the inclusion of disabled students: a Q‐sort analysis     

Franco Zambelli  Raffaele Bonni 《欧洲特需教育杂志》2013,28(3):351-366

This paper presents a course of research into the beliefs of class teachers concerning the scholastic integration of children with disabilities. In the current situation in Italy, due to limited specialist training, the attitudes that teachers develop can constitute an obstacle to the full realization of scholastic integration. Of the 23 teachers who took part in the study, conducted using the Q‐sort methodology, some had direct experience with scholastic integration (with opinions both positive and negative); and others had no direct experience (but also had both positive and negative opinions). Using the Q‐sort system, the paper sets out to verify whether effectively the simple manifestation of positive or negative beliefs in relation to inclusion on the part of the teachers (whether they had direct experience or not) could be confirmed, and whether it lent itself to being developed in reference to specific areas of scholastic experience. From the factorial analysis of the Q‐data, four factors emerged that confirm our hypothesis regarding the existence of different beliefs among teachers.  相似文献   

Application of the Levenshtein Distance Metric for the Construction of Longitudinal Data Files     

Harold C. Doran  Paul B. Van Wamelen 《Educational Measurement》2010,29(2):13-23

The analysis of longitudinal data in education is becoming more prevalent given the nature of testing systems constructed for No Child Left Behind Act (NCLB). However, constructing the longitudinal data files remains a significant challenge. Students move into new schools, but in many cases the unique identifiers (ID) that should remain constant for each student change. As a result, different students frequently share the same ID, and merging records for an ID that is erroneously assigned to different students clearly becomes problematic. In small data sets, quality assurance of the merge can proceed through human reviews of the data to ensure all merged records are properly joined. However, in data sets with hundreds of thousands of cases, quality assurance via human review is impossible. While the record linkage literature has many applications in other disciplines, the educational measurement literature lacks details of formal protocols that can be used for quality assurance procedures for longitudinal data files. This article presents an empirical quality assurance procedure that may be used to verify the integrity of the merges performed for longitudinal analysis. We also discuss possible extensions that would permit merges to occur even when unique identifiers are not available.  相似文献   

The Byzantines and Saladin: Some Further Arguments     

Savvas Neocleous 《Al-Masaq: Islam & the Medieval Mediterranean》2013,25(2):204-221

This is the second of two articles by the same author arguing against the thesis that there was a conspiracy between the Byzantine emperors and Saladin, sultan of Egypt and Syria, against the crusader states and the Third Crusade in the 1180s. While the focus of the first article was primarily on the Latin sources, the present study shifts the focus to the Arabic primary material, hitherto largely neglected or inadequately treated by modern historians. Through a critical re-examination and re-interpretation of the Arabic sources, backed by the introduction and discussion of new Latin material when necessary, this article presents expanded arguments on the relations between the Byzantine Empire, the Sultanate of Konya and Saladin in the 1180s. The conclusions lend further support to the view that the Byzantine rulers and Saladin never concluded an alliance against the Latin settlers of Outremer and the Third Crusade.  相似文献   

The De Kretser case: a note on Sri Lankan writing in English     

Pradeep Jeganathan 《Inter-Asia Cultural Studies》2013,14(3):446-451

Abstract

How is the content of a literary canon, or tradition to be configured? What counts as a literary archive? More than 25 years after Edward Said’s Orientalism (1978 Said, W. Edward. 1978. Orientalism, New York: Vintage.  [Google Scholar]), it seems reasonable to assume, that central to such traditions, would be the work of those who live and work in the society that gives rise to it. In this review, such a location of Michele de Kretser’s new novel, The Hamilton Case, is offered, as a caution to metropolitan literary critics who continue to approach Sri Lankan writing in English, as Christopher Columbus approached ‘America’. It is argued that the novel owes much to, and can be read as echoing and elaborating the detective fiction of S.W.R.D. Bandaranaike, who was, also, the fourth Prime Minister of Ceylon (Sri Lanka), 1956–59.  相似文献   

The Will to Be Unveiled: Sufi Autobiographies in Classical Sufism     

Arin Salamah-Qudsi 《Al-Masaq: Islam & the Medieval Mediterranean》2012,24(2):199-207

While autobiography as a special genre increasingly occupies an important position in modern scholarship, independent Sufi autobiographies still require additional and detailed examination. The current paper seeks to examine two spiritual autobiographies known very well in the history of Sufism: Al-?akīm al-Tirmidhī's Bad? sha?n, and Rūzbihān al-Baqlī's Kashf al-asrār. References to these works in modern research do not go beyond the assumption that they may represent visionary autobiographies, dreams, and mystical, extraordinary experiences and states. In the framework of this paper, we consider it essential to regard both texts as serious indicators of different realities, contexts, and mystic discourses.  相似文献

The accessibility of Chinese local government Web sites: An exploratory study     

Yuquan Shi 《Government Information Quarterly》2007

With the rapid development of Chinese e-government, Chinese citizens are encouraged to access e-government services as their convenience. However, the accessibility of Chinese e-government Web sites has been overlooked. This research study tries to provide an overview of the accessibility of Chinese local government Web sites. Three hundred twenty-four Chinese local government Web sites were examined to find out how accessible they are with reference to the Web Content Accessibility Guidelines 1.0 (WCAG) published by the World Wide Web Consortium (W3C). This research found that all the surveyed Chinese e-government Web sites failed one or more W3C's accessibility measures and thus many disabled Chinese people may have substantial problems to access them. Several valuable recommendations are made based on the research findings and the China's actual conditions.  相似文献   

Finding and explaining differences: A reply to Gudykunst and Hammer     

Richard L. Wiseman  Hiroko Abe 《Int J Intercult Relat》1984,8(1):11-16

A rejoinder to Gudykunst and Hammer's critique of a recent paper is presented. We argue that their position is based on two mutually exclusive propositions and cannot therefore be credible. We continue to maintain that the evidence on intercultural effectiveness shows both culture-general and culture-specific components.  相似文献
