This paper proposes a robust version of the unscented transform (UT) for one-dimensional random variables. It is assumed that the moments are not exactly known, but are known to lie in intervals. In this scenario, the moment matching equations are reformulated as a system of polynomial equations and inequalities, and it is proposed to use the Chebychev center of the solution set as a robust UT. This method yields a parametrized polynomial optimization problem, which in spite of being NP-Hard, can be relaxed by some algorithms that are proposed in this paper. 相似文献

The present study aims to critically interrogate the role of Critical Thinking (CT) in English language education in Chile through the analysis of teacher educators’ and postgraduate students’ perceptions and understandings of CT in relation to their academic trajectories through university. Five postgraduate students and five teacher educators from three different Masters of Teaching English as a Foreign Language (MTEFL) programs agreed to take part in the research. Informed by a qualitative paradigm, semi-structured interviews were conducted aimed mainly at (1) unpacking teacher educators’ and postgraduate students’ understandings of CT; (2) investigating postgraduates’ views of the place of critical thinking in their English teacher education training; (3) examining the ways in which teacher educators deal with CT in their pedagogies; and (4) identifying students’ preparedness to approach reading and writing critically, as viewed by both groups of participants. Analysis of responses revealed, on the one hand, students’ recognition of CT skills as necessary to succeed in academic life and, on the other, great concerns for the limited importance accorded to teaching these skills in teacher education courses. Teacher educators’ responses generally showed an increasing interest in trying to incorporate the teaching of CT skills in their pedagogies, but admitted to an overall lack of consistency in the implementation process. The paper concludes with critical questions about the perceived pedagogical mismatches between teacher educators’ and postgraduate students’ perceptions of the role of CT in their academic journeys, and about the role of Chilean teacher education programs in addressing these issues. 相似文献

The Catabacteriaceae is a new bacterial family with a unique member: Catabacter hongkongensis is a strictly anaerobic, non-sporulating, Gram-positive coccobacillus that is phylogenetically related to some clostridial
clusters. Little is known of its epidemiology and environmental distribution, but the inclusion of its 16S rRNA gene sequence
in GenBank has allowed it to be detected qualitatively. As a first approach for prospective surveys, a real-time polymerase
chain reaction (PCR) procedure to identify C. hongkongensis has been developed. The presence of Catabacteriaceae in 29 water bodies subjected to possible human or animal impact has
been investigated. Four of them were positive. The results confirm that highly polluted water can contain C. hongkongensis. 相似文献

This article presents the main terms of the racial contract, as they appear in the subcontracts of Mills’ theory, such as the spatial, epistemological, cognitive subcontracts. It is important to keep in mind that these subcontracts are by no means separate and represent analytical moments of the main contract. Furthermore, other than its institutional form, education is not a separate sphere from the racial contract. Finally, I end with the racial contract’s gaps to determine the possibility of its own demise, which requires the active signing off from the terms of the contract. That is, I sketch ideas about ways to counteract (i.e., counter-write) the racial contract as part of a corrective to the history that interpellates people of color as its targets. Both Whites and people of color have a stake in the rewriting of the contract, where in the end they are imagined as neither Black nor White but free. In this last portion, I spend some text on what Whites’ role may look like in signing off the contract, such as the case of white ‘race traitors’ within the white abolitionist proposal, recast as the ‘epistemological traitor’ in education. 相似文献

Reduced state support of film financing in Europe requires the creation of an efficient market of private cinema financiers. Principal-agent models with and without common consent over film risk show that the two main problems of film financing (high risk and lack of collateral for the borrower) may be solved if the financier achieves economies of scale in costs of capital and is efficient in information gathering. Conversely, the pathology of a market with inefficient financiers includes: film financial rationing, adverse selection, and refusal of financial support to otherwise profitable film projects. From the normative point of view, the creation of efficient financiers would be fostered by institutional changes that promote market thickening and risk spreading (the case of the USA) instead of simple forms of risk shifting (the case of Italy). 相似文献

The Moodle platform has been used to put into practice an ongoing evaluation of the students’ Physics learning process. The evaluation has been done on the frame of the course General Physics, which is lectured during the first year of the Physics, Mathematics and Electronic Engineering Programmes at the Faculty of Science and Technology of the University of the Basque Country (UPV/EHU). A test bank with more than 1000 multiple-choice questions, including conceptual and numerical problems, has been prepared. Throughout the course, the students have to answer a 10-question multiple-choice test for every one of the blocks the course is divided in and which were previously treated and worked in the theoretical lectures and problem-solving sessions. The tests are automatically corrected by Moodle, and under certain criteria, the corresponding mark is taken into account for the final mark of the course. According to the results obtained from a statistical study of the data on the student performances during the last four academic years, it has been observed that there exists an actual correlation between the marks obtained in the Moodle tests and the final mark of the course. In addition, it could be deduced that students who have passed the Moodle tests increase their possibilities of passing the course by an odds ratio close to 3. 相似文献
