Speech development in young children has been studied quite often in a linsi:uistic (mainly phonological) way, with respect to the production and perception ability of infants and young children (Menyuk:,1971;Locke,1983;Ferguson,1986;Jusczyk,1986). Development of children's speech and their acoustic-phonetic correlates, however, are still considered as an area of research in which many aspects ...

for an unknown vector of parameters β0 and an unknown univariate function τ(·). This model is implied by many important limited dependent variable and regression models, as discussed in Ruud (1986) and Stoker (1986). Consistent estimators for β0, up to an unknown scale factor, have been developed by Ruud (1986), Stoker (1986), Powell, Stock, and Stoker (1989), Ichimura (1993), and others. In th...

In the original formulation of Hopfield’s memory model, the learning rule setting the interaction strengths is best suited for orthogonal words. From the point of view of categorization, this feature is not convenient unless we reinterpret these words as primordial categories. But then one has to complete the model so as to be able to store a full hierarchical tree of categories embodying subca...

Hummingbirds have received considerable attention in studies of feeding and energy regulation because of their small size, frequent feeding, and their use of energy-rich sugar solutions (e.g. Diamond et al. 1986, Ewald and Carpenter 1978, Hainsworth 1981). They store nectar in a crop, and this internal reservoir supplies energy between foraging bouts (Hainsworth and Wolf 1972, Karasov et al. 19...

The early literature on women with alcoholic husbands outlined a predominantly negative view of these women. Such women were seen as neurotic, poor copers who were obsessed with controlling their husbands’ drinking. They were seen to have partnered alcoholic men in order to satisfy their own pathological needs (Kalashian 1959; Whalen 1953). It was further asserted that some women would sabotage...
