In this paper, we propose a new relational schema （R-schema） to XML schema translation algorithm, VQT, which analyzes the value cardinality and user query patterns and extracts the implicit referential integrities by using the cardinality property of foreign key constraints between columns and the equi-join characteristic in user queries. The VQT algorithm can apply the extracted implied referential integrity relation information to the R-schema and create an XML schema as the final result. Therefore, the VQT algorithm prevents the R-schema from being incorrectly converted into the XML schema, and it richly and powerfully represents all the information in the R-schema by creating an XML schema as the translation result on behalf of the XML DTD. 相似文献

ABSTRACTThe growing prevalence and severity of mental health difficulties across university student populations is a critical issue for universities and their wider communities. Yet little is known about student perspectives on the stressors in university environments and the steps that universities could take to better support student mental wellbeing. This article reports on a study that collected and analyzed 2776 student responses to the question: What can be done to improve student wellbeing? Students made diverse recommendations that fell into seven categories: Academic teachers and teaching practices; student services and support; environment, culture and communication; course design; program administration; assessment; and student society activities. The findings from our study offer important insight to university educators and administrators about the role they can play in better supporting student wellbeing and preventing the high rates of psychological distress. We argue that the process of seeking and acting on students’ suggestions fosters students’ sense of inclusion and empowerment, and this is critical given that the goal of improving student mental wellbeing can only be achieved through an effective partnership between students and institutional actors. 相似文献

With the rapid growth of the Web, the volume of information on the Web is increasing exponentially. However, information on the current Web is only understandable to humans, and this makes precise information retrieval difficult. To solve this problem, the Semantic Web was proposed. We must use ontology languages that can assign data the semantics for realizing the Semantic Web. One of the representative ontology languages is the Web ontology language OWL, adopted as a recommendation by the World-Wide Web Consortium （W3C）. OWL includes hierarchical structural information between classes or prop- erties. Therefore, an efficient OWL storage model that considers a hierarchical structure for effective information retrieval on the Semantic Web is required. In this paper we suggest an XPath-based OWL storage （XPOS） model, which includes hierarchical information between classes or properties in XPath form, and enables intuitive and effective information retrieval. Also, we show the comparative evaluation results for the performance of the XPOS model, Sesame, and the XML file system-based storage （XFSS） model, in terms of query processing and ontology updating. 相似文献

AbstractChina is characterized by a long history, vast land, huge population and diversity unprecedented in world history. In addition, she is a unique case that has successfully completed the transition from empire to the nation-state. Therefore, her historical independence and her continuity become very important subject areas for research, and the concept “empire” re-emerges as a major means of explanation. The essential defining features of empire are tolerance and expansion. I have been reviewing discourses on “China as Empire,” looking at studies of the tributary system, the civilization-state, and the Tianxia view raised from both inside and outside of China. A common characteristic of these discourses is the perception that the past, present and future of China cannot be fully explained by Western concepts such as nation-state. They also reveal that the supposed continuity with the past, which is overemphasized in many studies, does not necessarily always correspond with historical reality. The key focus of the empire discourses is the project of future China. Finally, I put a particular emphasis upon the “perspective of peripheries” in order to find ways to demonstrate the benefits of viewing China as an empire, while also overcoming the weaknesses of empire theory. It is the reason why I apply to the analysis of the empire discourses the “compound state” theory incubated as a way of reunification of the Korean Peninsula. 相似文献

Involving students in peer review has many pedagogical benefits, but few studies have explicitly investigated relationships between the content of peer reviews, student perceptions and assessment outcomes. We conducted a case study of peer review within a third-year undergraduate subject at a research-intensive Australian university, in which we examined: (1) students’ perceptions of the peer review process before and after peer review, (2) content of the peer reviews and what kinds of feedback were adopted and (3) the effect of participation in peer review on performance (grades) in the assessment task. Students overwhelmingly perceived peer review to be beneficial, and the opportunity to participate in peer review resulted in a significant improvement in the quality of work submitted for assessment. Students who benefited most from peer review were those of below-median performance, and the magnitude of benefit was related to the degree to which students engaged with the peer review process. Our study confirms that participation in peer review can lead to important improvements in performance and learning outcomes. 相似文献

A feature of Australian Higher Education over the last 10 years has been the increased numbers of international students. This feature has been perceived to have great potential for enhanced learning for all students – both international and domestic. Yet, student surveys and research clearly indicate that there is very little interaction occurring between domestic and international students. This article reports on a study that investigated the extent to which university teaching can promote interaction between students from diverse cultural and linguistic background. Using an innovative video-analysis methodology, the research found that academics engage in a variety of activities to encourage interaction between student groups. In order to assist academics in planning interaction, one of the main findings of the study was the development of ‘The Interaction for Learning Framework (ILF)’, that identifies key dimensions for curriculum design that can be used by academics to inform ways that they can enhance interaction between diverse student groups within teaching and learning contexts. 相似文献

With the majority of undergraduate teaching in Australian higher education being undertaken by casual academics, ensuring adequate support for these staff to access support and professional development relating to teaching and learning is imperative. In this article, we profile the development and implementation of a university-wide strategic framework for training, support and recognition of the contributions of sessional teachers. The design of this framework was informed through an iterative process of research and consultation with key institutional stakeholders and has resulted in changes at a policy level as well as in the delivery of professional development programs for sessional teaching staff. The opportunities and challenges of this approach are discussed, as well as future directions and broader considerations for the support of sessional teachers in the Australian higher education context. 相似文献

Recently, proponents of interfirm R&D collaboration have emphasized its benefits. We develop a dynamic model of Schumpeterian competition to examine whether such collaboration is indeed beneficial in the long run. We find that interfirm R&D collaboration is more likely to be a losing strategy when partners form alliances mainly to reduce R&D costs. On the other hand, partners collaborating to seek synergy by accessing each other's complementary assets/capabilities are more likely to be successful. Our study suggests that firms should not use strategic alliances merely to reduce R&D costs in a catch-up situation or to avoid head-on competition with rivals. 相似文献

This study investigates English-speaking media’s legitimation of smartphone uses by Syrian refugees to explore how “otherness” is negotiated through technologies. Qualitatively examining the media coverage of the Syrian refugees’ use of smartphones between early 2015 and early 2017, we identified rhetorical devices and narrative strategies. The findings indicated a gradual shift in mediated legitimation strategies. In this process, two major themes emerged: (1) strategies to legitimate uses of technology and (2) demystifying refugees. The first theme identified that media articles focused on refugees’ instrumental uses of smartphones over the emotional uses as a legitimation strategy, utilizing metaphors and referencing third parties. The second theme showed media coverage further debunked conflation over poverty and precarity while negotiating otherness. Over time, the media coverage started to fall into the “humanitarian imaginary” of refugees by keeping them at the margins as people who need aid, largely limiting their legitimated mobile phone use to pragmatic uses. The findings contribute to understanding how media coverage can shape the way people make sense of the refugee population at a moment in time of technological appropriation amid ongoing political crises. 相似文献

Ultrasound is being investigated as a trigger mechanism to deliver high concentrations of chemotherapy drugs to cancerous tissues using polymeric micelles. In this paper, we examined the kinetics of acoustic release of doxorubicin using stabilized and non-stabilized micelles. Kinetic models were used to regress release and re-encapsulation time constants for three different compounds, namely non-stabilized Pluronic® P105 micelles, P105 micelles stabilized using an interpenetrating network of N,N-diethylacrylamide and micelles formed by PEO-b-poly(NIPAAm-co-HEMA-lactaten). Results showed that the kinetic release constant (kr) depends on the micellar system under investigation. On the other hand, there is no statistically significant difference between re-encapsulation rate constants for stabilized and unstabilized micelles. We hypothesize that kr depends on the degree of cross-linking or stabilization. 相似文献
