title: Modelling and simulation: An overview

authors: McAleer, Michael

subjects: modelling

abstract: The papers in this special issue of Mathematics and Computers in Simulation cover the following topics: improving judgmental adjustment of model-based forecasts, whether forecast updates are progressive, on a constrained mixture vector autoregressive model, whether all estimators are born equal: the empirical properties of some estimators of long memory, characterising trader manipulation in a limit-order driven market, measuring bias in a term-structure model of commodity prices through the comparison of simultaneous and sequential estimation, modelling tail credit risk using transition matrices, evaluation of the DPC-based inclusive payment system in Japan for cataract operations by a new model, the matching of lead underwriters and issuing ﬁrms in the Japanese corporate bond market, stochastic life table forecasting: a time-simultaneous fan chart application, adaptive survey designs for sampling rare and clustered populations, income distribution inequality, globalization, and innovation: a general equilibrium simulation, whether exchange rates affect consumer prices: a comparative analysis for Australia, China and India, the impacts of exchange rates on Australia’s domestic and outbound travel markets, clean development mechanism in China: regional distribution and prospects, design and implementation of a Web-based groundwater data management system, the impact of serial correlation on testing for structural change in binary choice model: Monte Carlo evidence, and coercive journal self citations, impact factor, journal inﬂuence and article inﬂuence

title: Psychometric properties of the movement-specific reinvestment scale for Chinese children

authors: Ling, Fiona C.M.

abstract: The propensity for movement-specific reinvestment (conscious attention to and control of body movements) is associated with disrupted movement in a variety of circumstances. Movement-specific reinvestment has been shown in adults but not in children, as a validated psychometric instrument for children does not exist. The aim of this study was to examine the psychometric properties of a movement-specific reinvestment scale adapted specifically for Chinese children (MSRS-CC). Five hundred and thirty-two Chinese pre-adolescents aged 7–12 yrs completed the MSRS-CC and a sub-sample completed the questionnaire again three weeks later. Another sub-sample also completed the Coordination and Health subscales of the Physical Self-Description Questionnaire (short form; PSDQ-S). All questionnaires were completed during normal school days. A random half of sub-sample two completed the MSRS-CC before the PSDQ-S and the other half completed the questionnaires in reverse order. Confirmatory factor analyses demonstrated sound internal validity for the Scale's two-factor model. Acceptable internal reliability and satisfactory test–retest reliability were evident. Convergent and discriminant validity with the Coordination and Health subscales of the PSDQ-S was also tested, but the former was unexpectedly low. Future research using objective measures of motor proficiency was recommended. The MSRS-CC is potentially a valuable tool for understanding movement control by children in research as well as in clinical and educational settings.

title: Taking Taniwha seriously

authors: Kingsbury, Justine

subjects: intercultural understanding

abstract: Taniwha are powerful water creatures in te ao Māori (the Māori world/worldview). Taniwha sometimes afect public works in Aotearoa New Zealand: for example, consultation between government agencies and tangata whenua (the people of the land) about proposed roading developments sometimes results in the route being moved to avoid the dwelling place of a taniwha. Mainstream media responses have tended to be hostile or mocking, as you might expect, since on the face of it the dominant western scientifc worldview has no place for beings like taniwha. However, in the 2020s, there appears to be an increased willingness to engage with te ao Māori. In this spirit, this paper proposes a way for non-Māori to begin to take taniwha more seriously, taking as its starting point the work of Dan Hikuroa on the practical usefulness of taniwha pūrākau (traditional narratives) in encoding information about natural hazards. The focus of this paper is narrow, but aspects of the strategy it proposes may be generalisable both to other aspects of te ao Māori and to other bicultural and multicultural contexts.
