    Traditionally, the LOTE teacher is positioned as the learners' language model. Ingram argues that since the L2 is both the target and the medium of instruction 'the teacher is often the principal (if not sole) model of the language for the student'. This implies that the language of instruction should define the particular teaching method. In practice, however, the teacher speaks and writes model dialogues or more precisely model texts that act as the major source of L2 input, especially in the initial stages of learning the language. Model dialogues are those 'simulated conversation dialogues found at the beginning of textbook language lessons' presented to learners at any time during a class. These models appear not only in textbooks, but also on cassette tapes, in computer 'interactive' multimedia software packages, on photocopied worksheets, the blackboard, and from teachers' mouths. Erickson describes model dialogues as 'stilted' and sometimes 'stereotypical'. The purpose of this paper is to examine the relationships between model dialogues, teachers, learners, and other stake holders by investigating what aspects of social reality model dialogues attempt to characterise; why model dialogues are used extensively as motifs representing actuality, motifs which learners (and teachers) are expected to memorise and use in the future; and whether it would be possible to teach and learn Japanese without using model dialogues.

    Journal Article
    The advent of public-sector managerialism has brought with it a new principle of police accountability in Western democracies such as Australia and Britain. The new accountability gives emphasis to managerial rather than legal or public-interest standards, favours external oversight combined with self-regulation rather than centralized control, and promotes risk management rather than rule enforcement. This article makes use of the experience of an Australian police force to show that the new accountability has not been successful in holding police accountable, while elements of the old accountability have re-emerged to dominate public debates. It is argued that in the area of police governance, the neo-liberal state does not necessarily pursue a coherent strategy of 'acting at a distance' (cf. Miller and Rose 1990), partly because of the inability of accountability technologies to deliver substantially the promised policy outcomes and partly because of the sensitivity of its political arm to the public's moral outrage against corruption (cf. Garland 1 996).

    The influence of the flux flow on a.c. loss and magnetic penetration process in superconductors has been investigated. Asymptotic solutions of magnetic and electric fields and a.c. loss are presented in the form of a power series of [Lambda], the normalized frequency of the external a.c. magnetic field. The results show that the flux flow retards the response of inner magnetic field to the external one, which results in a deviation from the critical state model and a non-hysteretic loss. In the cases of H0>Hp, the deviation from the critical state is in the order of the second power of [Lambda]. The induced electric field and the macro-penetration depth are decreased by the slowdown of the flux movement, giving a negative contribution to the a.c. loss. However, the negative contribution is compensated by the increase of the current density, leading to a net increase of the a.c. loss. As a result, the a.c. loss exhibits a positive dependence on the frequency and the amplitude of the external magnetic field.

    Journal Article
    Low-temperature thermal expansion and its correlation with oxygen nonstoichiometry have been studied for Bi1.7Pb0.3Sr2Ca2Cu3O10+y samples. An anomalously big jump of the thermal expansion in the c direction of Bi1.7Pb0.3Sr2Ca2Cu3O10+y has been observed at a temperature slightly above the superconductivity transition temperature. The corresponding temperature and the magnitude of the jump are found to be correlated with the oxygen nonstoichiometry, carrier concentration and superconductivity. The results reveal that the anomalously big jump of the thermal expansion is an electron-assisted lattice softening transition. Its correlation with the superconductivity suggests that phonon-electron interaction still plays a certain role in the superconductivity in high-Tc cuprates.
