In so-called ‘integrated’ audio-visual language courses, still pictures (ie slides, film stills, flannel board figures, drawings photographs, etc) have two possible functions: firstly, they simu- late the enunciative aspects of communication n i a foreign language, and secondly, they serve as equivalents to the foreign linguistic signs used i n this communication. The first of these functions consists of an artificial reproduction at a classroom level of the non-linguistic environments in which these foreign forms can be used. The second function is a kind of transcoding system, which works in a visual manner on the meanings of these linguistic forms. These two functions, each in accordance with their own particular characteristics, have the effect of providing an interpretation to the foreign expressions and thereby precluding the necessity of any direct translation into a level of language known to the class.  相似文献

Gill, P. E. 1976. The Relationship Between Mental Ability and Eight Background Variables. Scand. J. educ. Res. 20, 135‐145. Multiple regression is seen as a search technique when applied to IQ. test data. The results from such a search are stochastic rather than deterministic. Because of this it is imperative that comprehensive samples be studied. The sample in this study (n = 3,695) was representative of the population of Irish 6‐ to 12‐year‐olds. The results are surprising in that the total variance explained by predictors such as SES, sex, family size, position in family, absenteeism and urbanity is never more than 8 %. Differences in how predictors behave with IQ and Vocabulary are noted. SES, family size and urbanity are the most significant predictors. When Vocabulary is the criterion, sex differences (in favour of girls) emerge consistently. It is contended that pupils of low intelligence go absent more often than their peers. The total variance explained was increased when homoscedasticity was reduced by stabilizing criterion variance (by reducing age span).  相似文献

This article considers the counter-intuitive observation that some of the wealthiest nations can feature low tertiary graduation rates (e.g. Austria, Germany, and Switzerland). It also considers the observation that many countries with high tertiary graduation rates show low levels of social equity, while many countries with low tertiary graduation rates show high levels of social equity. These observations are considered through the lenses of institutional perspectives, and specifically welfare and production régime theories. The analysis elaborates on educational attainment, patterns and key aspects of economic functioning and development, and educational attainment patterns and their relationship to social inequality.  相似文献

Abstract

The gender sexual politics of Liu Yu‐hsiu has been pivotal in the hegemonic ascendancy of Taiwan state feminism in recent years. Through an examination of Liu’s psychoanalytically mediated essays of cultural criticism, this article traces the contour of Liu’s sexual imaginary within the context of 1990s feminist and queer politics. Liu’s modernising project of gender equality, I argue, upholds heterosexual monogamy as a feminist ideal that seeks to purge all the masculine ills, including perversion and promiscuity. Meanwhile, queers and prostitutes come to be figured as the very negativity that must be repressed. Yet, like the Lacanian Real, they impinge on the symbolic order that Liu ordains as they thwart her desire to civilise sex.  相似文献

Abstract

The aim of this study was to investigate spatiotemporal and kinematic changes between the initial acceleration, transition and maximum velocity phases of a sprint. Sagittal plane kinematics from five experienced sprinters performing 50-m maximal sprints were collected using six HD-video cameras. Following manual digitising, spatiotemporal and kinematic variables at touchdown and toe-off were calculated. The start and end of the transition phase were identified using the step-to-step changes in centre of mass height and segment angles. Mean step-to-step changes of spatiotemporal and kinematic variables during each phase were calculated. Firstly, the study showed that if sufficient trials are available, step-to-step changes in shank and trunk angles might provide an appropriate measure to detect sprint phases in applied settings. However, given that changes in centre of mass height represent a more holistic measure, this was used to sub-divide the sprints into separate phases. Secondly, during the initial acceleration phase large step-to-step changes in touchdown kinematics were observed compared to the transition phase. At toe-off, step-to-step kinematic changes were consistent across the initial acceleration and transition phases before plateauing during the maximal velocity phase. These results provide coaches and practitioners with valuable insights into key differences between phases in maximal sprinting.  相似文献
