Using performance assessment in secondary school mathematics: an empirical study in a Singapore classroom
No full textThis article reports an exploratory study on using performance assessment in mathematics instruction in a high-performing secondary school in Singapore. An intact mathematics class participated in the study, and received chapter-based performance tasks as intervention during regular mathematics lessons for about one and a half school years. The performance tasks used included authentic and/or open-ended tasks. The students’ academic achievements and attitudes in mathematics were compared with a comparison class that did not receive the intervention. Both quantitative and qualitative data were collected, mainly through questionnaire surveys, performance task tests, conventional school exams, and interviews with students and teachers. The results suggest that the students receiving the intervention performed significantly better than their counterparts in solving conventional exam problems, and in general they also showed more positive changes in attitudes towards mathematics and mathematics learning. The students from the experimental class also expressed positive views about the benefits of using performance tasks in promoting their ability in higher order thinking, though no statistically significant difference was detected between the two classes of students in solving unconventional tasks before and after intervention. Overall, the results appear to support teachers’ using contextualised problems in real life situations and open-ended investigations in students’ learning of mathematic
The relationship between the exercise of political power and language during the cultural revolution in Inner Mongolia - 1967-1969
No full textThis is an analysis of the relationship between language contained in political documents and the exercise of power and authority from the Cultural Revolution in the Inner Mongolian Autonomous Region of the People's Republic of China from 1967 to 1969. It is based on analytic methods found in the works of Foucault, Bourdieu, Gramsci and others. The material analysed falls into four periods. The
first phase in 1967 saw the initial impact of the CR manifesting itself locally by causing conflict between two key entities in the IMAR - the army and student rebellion groups. The response by the Centre to this was the conduct of dialogues with the local groups, resulting in the issuing of a key document, the '13th April Decision,' to 'resolve' the local problems and impose hegemony from the Centre, through promoting standardised narratives and a specific ideology - CR Maoism. The -second phase from 1967 to 1968 saw the implementation of this strategy through the attack on the local leader, Ulanfu. During this period the discourse to 'handle' the region was articulated promoting a narrative and ideology from the Centre in Beijing of power based on class, excluding any assertions of the primacy of ethnicity and nationality locally. The third phase from 1968 to 1969 saw the promotion by the Centre of the newly installed leader, Teng Haiqing, using this new discourse. In this period, a local enemy - the Inner Mongolian People's Party - was gradually articulated. The final phase in 1969 saw the social turmoil and violence caused by the purge of those claimed to be members of this party, and the withdrawal of support from the Centre for Teng Haiqing, resulting in his use of a self-critical language, the creation of an adapted narrative and ideology, conveyed through a new discourse in which the key issues of class and ethnicity/nationality were approached in different ways.
The focus of this thesis is the signification of power in language and discourse through this period, and the techniques by which to describe and understand this

No full textIn this paper we present our method for acquiring and integrating knowledge from discourse using Belief Augmented Frames (BAFs) and Discourse Representation Theory (DRT). We show how several common discourse phenomena can be evaluated and integrated using BAFs and DRT, and introduce KAINA (Knowledge Acquisition and Integration in Nave Agents), our implementation of BAFs for the collection and integration of knowledge, particularly from spoken discourse
Why hedge? Extent, nature, and determinants of derivative usage in U.S. municipalities
No full textUsing a hand-collected dataset of over 300 observations of large U.S. cities and counties, this paper investigates the extent, nature and determinants of derivatives usage in the municipal sector.Over half of our sample entities engage in derivative transactions and a vast majority of these transactions are intended to manage interest rate risk. Swaps, by far, are the most popular derivative instrument. In terms of the determinants of derivative usage,we find that the propensity to use derivatives as well as the extent of derivative usage is higher for municipalities that are larger and more financially constrained. We do not find growth to be related to municipal derivative usage. Contrary to suggestions made in the popular press, we fail to find managerial opportunism to be a significant factor in municipal derivative usage. We also find that more sophisticated managers of large municipalities and less sophisticated managers of small municipalities are more likely to engage in derivative transactions.Peer reviewe
A study on the reliability of consecutive k-Out-of-n: G systems based on Copula
No full textThe computation of reliability characteristics of a system that consists of dependent components is sometimes difficult especially when the type of dependence is not known. This article introduces the copula method to calculate the reliability of dependent consecutive k-out-of-n: G systems. The components in these systems are dependent on each other and the dependency may be either linear or nonlinear. The copula is a popular tool for modeling the dependence structure of data. It contains the information about the dependency structure of a vector of random variables and can capture nonlinear dependence. Based on the copula theory, the article analyzes the consecutive k-out-of-n: G systems and gets the reliability indexes. Finally, some numerical examples are presented to illustrate the results obtained in this article.Peer reviewe
