Developing the knowledge and practical skills for implementing inclusive education is a legislative and policy imperative for contemporary graduate teachers. In this qualitative study, the authors investigated the experiences of 18 preservice teachers during their practical school placements in primary and secondary school settings and the impact of these experiences on their attitudes towards students with special needs and their readiness to teach in mainstream inclusive settings. Sixteen of the participants had completed 2 or more placements. Data were collected using semistructured interviews and analysed to categorise the observed and enacted practices and define themes that contribute to a deeper understanding of preservice teachers’ learning about inclusion through their practice in schools. The 4 identified themes show that contact, responsibility for instruction, modelled practices, and expectations for student learning all have significant impacts on the quality and outcomes of preservice teachers’ placements. Findings suggest that placement settings do not consistently represent contexts where aspiring teachers are exposed to the types of meaningful contact or successful experiences claimed to be fundamental preparation for inclusive practice. The implications for the preservice teachers themselves and for their future practice are discussed.

Two medium-depth ice cores were retrieved from Berkner Island by a joint project between the Alfred-Wegener-Institut and the British Antarctic Survey in the 1994/95 field season. A 151m deep core from the northern dome (Reinwarthhöhe) of Berkner Island spans 700 years, while a 181 m deep core from the southern dome (Thyssenhöhe) spans approximately 1200 years. Both cores display clear seasonal cycles in electrical conductivity measurements, allowing dating by annual-layer counting and the calculation of accumulation profiles. Stable-isotope measurements (both δ18O and δD), together with the accumulation data, allow us to estimate changes in climate for most of the past millennium: the data show multi-decadal variability around a generally stable long-termmean. In addition, a full suite of major chemistry measurements is available to define the history of aerosol deposition at these sites: again, there is little evidence that the chemistry of the sites has changed over the past six centuries. Finally, we suggest that the southern dome, with an ice thickness of 950 m, is an ideal site from which to gain a climate history of the late stages of the last glacial and the deglaciation for comparison with the records from the deep Antarctic ice cores, and with other intermediate-depth cores such as Taylor Dome and Siple Dome.

This article examines the flexibility of the Johnson system of distributions by assessing its performance in terms of modeling crop yields for the purpose of setting actuarially fair crop insurance premiums. Using data from corn farms in Illinois coupled with Monte Carlo simulation procedures, we found that average crop insurance premiums computed on the basis of the Johnson system provide reasonably accurate estimates even when the data are normal or come from a non-normal distribution other than the Johnson system (i.e., a beta). These results suggest that there is potential for using the Johnson system to rate previously uninsured crops that do not have historical insurance performance data upon which to base premium calculations.

Factors affecting the adoption of crop insurance, forward contracting, and spreading sales are analyzed using multivariate and multinomial probit approaches that account for simultaneous adoption and/or correlation among the three risk management adoption decisions. Our empirical results suggest that the decision to adopt crop insurance, forward contracting, and/or spreading sales are correlated. Richer insights can be drawn from our multivariate and multinomial probit analysis than from separate, single-equation probit estimation that assumes independence of adoption decisions. Some factors significantly affecting the adoption of the risk management tools analyzed are proportion of owned acres, off-farm income, education, age, and level of business risks.

The highly regular orthographies (spelling systems) of many nations expedite literacy development, and their children experience a rapid transition from early literacy (learning to read and write) to sophisticated literacy (reading and writing to learn). In contrast, English orthographic complexity impedes literacy development, particularly for weak readers (Galletly & Knight, in press a, b). This article proposes a model of differential disadvantage of Anglophone weak readers due to cognitive processing weakness and the high cognitive load of learning to read and write English. The disadvantage is differential, first with Anglophone weak readers disadvantaged compared to weak readers in nations with regular orthographies, and second, with subgroups of Anglophone weak readers being more disadvantaged, depending on their levels of language skills and cognitive processing efficiency. Anglophone weak readers with pre-existing language disorder experience the highest levels of differential disadvantage. Weak cognitive processing and automisation in the face of continuing high cognitive load seems a basis for them frequently showing comorbidities, with features of multiple disorder categories (Catts, Adlof, Hogan, & Ellis Weismer, 2005), including autism spectrum disorder (ASD), attention deficit/hyperactivity disorder (ADHD), auditory processing disorder, motor weakness, and social and behavioural impairment. The model is a useful framework for considering the instructional needs of weak readers. Areas where research is needed for building ways forward in optimising literacy development is discussed.

Decision-making regarding intensive instructional support for children with special needs should build from children's instructional needs, and not from diagnostic labelling and criteria for funding eligibility. Cognitive referencing, the use of results on intelligence and language quotients to decide children's academic options and funding eligibility, is established as inappropriate practice yet continues to be used by many education systems. This paper discusses systemic practices in Australia, the United Kingdom and the United States, and then details four cases of children ‘framed’ by their tests, that is, experiencing unwarranted disadvantage due to how they were positioned by their tests and diagnoses. The final section makes recommendations for considerations needed in the improving of Australian education of children with special needs.

Primate retinal ganglion cells that project to the magnocellular layers of the lateral geniculate nucleus (M) are much more sensitive to luminance contrast than those ganglion cells projecting to the parvocellular layers (P). We now report that increasing contrast modifies the temporal-frequency response of M cells, but not of P cells. With rising contrast, the M cells' responses to sinusoidal stimuli show an increasing attenuation at low temporal frequencies while the P cells' responses scale uniformly. The characteristic features of M-cell dynamics are well described by a model originally developed for the X and Y cells of the cat, where the hypothesized nonlinear feedback mechanism responsible for this behavior has been termed the contrast gain control (Shapley & Victor, 1978, 1981; Victor, 1987, 1988). These data provide further physiological evidence that the M-cell pathway differs from the P-cell pathway with regard to the functional elements in the retina. Furthermore, the similarity in dynamics between primate M cells and cat X and Y retinal ganglion cells suggests the possibility that P cells, being different from either group, are a primate specialization not found in the retinae of lower mammals.

The work described in this paper is a contribution to the general problems of rearing the larvae, and growing the spat of the European flat oyster, Ostrea edulis L.
The specific aspect of the problem dealt with in detail is the place taken by minute motile organisms (naked dinoflagellates and other unicellular algae) in the food requirements of the developing veliger larvae.
Six such flagellate organisms, ranging in size from 1·5 to 7 μ in diameter, have been isolated from sea water, and are maintained in pure culture, under conditions described. Pending specific identification, these are denoted by letter-labels only. These organisms have been used, over a period of years, in feeding experiments with oyster larvae.

There is mounting evidence to support the belief that not all students learn to spell by immersion in reading and writing alone. The intervention to teach spelling described in this paper combines the direct instruction in the study of words together with the use of spelling in an integrated language system. Students in a regular classroom were categorised into three groups (good spellers; average spellers and poor spellers including those identified as average to good readers). Specific areas explored included students’ attitudes, knowledge and spelling ability in isolation and in context. Results suggested the intervention was effective for all students, especially in terms of their knowledge about the language system, strategies and their own spelling misconceptions.

Multilayer metallizations of Pd/Ge/Pd, with different thickness ratios of Ge and Pd, were deposited onto n-type InP by means of electron beam evaporation. The specimens were then annealed in flowing N2 gas at temperatures ranging from 250 to 425°C for various times. Transmission electron microscopy (TEM), energy dispersive x-ray spectroscopy (EDX) and electron diffraction were used to identify the phase changes during reaction. The four point probe method was used for electrical resistance measurements. A Pd-In-P amorphous phase and a Pd2Ge compound formed during deposition. Subsequent annealing resulted in crystallization of the amorphous phase followed by epitaxial growth of Pd2InP(II) on InP at 350°C. At 425°C, Pd2InP(II) with Ge in solution, decomposed producing a contact with a lower specific contact resistance. The lowest contact resistances achieved were ∼10−5 Ωcm2. Further annealing led to more decomposition of InP, including presumably the Ge doped InP surface region, which corresponded to an increase in contact resistance.

Ohmic contact formation and thermal stability in a Au/Ge/Pd metallization to n-type InP, doped to a level of 1017 cm-3, have been investigated. Contact resistance was measured using a transmission line method, while microstructural changes were examined by means of TEM, EDX, CBED and SAD. Contacts became ohmic after annealing at temperatures ranging from 300°C to 375°C. A minimum contact resistance of 2.5×l0-6 Ω-cm2 was obtained after annealing at 350°C for 320s. The drop in resistance to ohmic behavior corresponded to the decomposition of an epitaxial quaternary phase (Au-Ge-Pd-P). Annealing at 400°C and above resulted in Au10In3 spiking into InP and a break down of contact lateral uniformity, which increased contact resistance.
