Discrepancy Hypothesis

Recent work by the present author has identified a sequence of events during joint play of mother and infant which may lead infants to process mothers' presentations of objects in a particular way. This sequence of events implies a special form of detection of discrepancy by infants. The present report is an attempt to determine whether a plausible alternative hypothesis, which also happens to be more parsimonious, can account for previously reported findings which are consistent with the discrepancy hypothesis. The alternative hypothesis states that infants' processing of objects either during mothers' presentations or during infants' independently initiated manipulations is determined by the duration of time infants previously devoted to manipulating the object. The findings contradict this alternative hypothesis, and in so doing, lend further support to the discrepancy hypothesis originally proposed.

Did preparations for the Second World War account for the precipitous drop in the growth rate of Soviet industrial production from 10–12 percent per annum in the period 1928–1937 to only 2–3 percent per annum in the period 1937–1940? According to some who study the Soviet economy the answer is “yes.” This view has been succinctly expressed by Stanley Cohn: “After 1937, the rising spectre of Hitler forced the Soviet leadership to shift resources into armaments on a massive scale. As a result, the growth rate fell drastically to 3.6 percent per year between 1937 and 1940.” Such a sequence of events, however, has never been empirically demonstrated. The purpose of this paper is to investigate formally the validity of this explanation, via aggregate production functions, particularly of the CES (constant elasticity of substitution) variety, as well as to explore an alternative hypothesis, espoused, among others, by Naum Jasny, Alec Nove and Warren Nutter. This hypothesis stresses a domestic factor as the major contributor to the disruption in industrial production: namely, the impact of Stalin's terror in the form of chaos-producing political purges.

Present Subject

ABSTRACTRecent work has suggested that phrasing occurs in prelinguistic vocalizations, and that audition significantly influences prelinguistic vocal development. The present report is about the continuing study of a child who is referred to as congenitally acochlear because he was born with complete bilateral absence of cochleas. The only prior report on the vocal development of an acochlear child was provided in a previous article in this journal about the present subject (Lynch, Oiler, & Steffens, 1989). Because this child was not producing meaningful speech during the 27 to 42 months of age in which he was studied, investigation of him provided a unique opportunity to observe prelinguistic vocal development in the complete absence of auditory information. In the prior study of the acochlear child, the analytical focus was on developmental changes in relations between his syllable characteristics and those of mature speech. In the present study, the analytical focus was on a recently introduced approach to the study of prelinguistic vocalizations involving the description of syllable groupings within a prosodic hierarchy. Adult judges identified a hierarchy of syllables embedded within utterances and utterances embedded within prelinguistic phrases in the acochlear child's vocalizations. Similar to the prelinguistic phrases of typically developing infants and infants with Down syndrome previously reported on (Lynch, Oller, Steffens, & Buder, 1995), the present child's prelinguistic phrases were characterized by a systematic lengthening of phrase-final syllables and cohesive temporal patterning. In addition, the durations of the acochlear child's prelinguistic phrases were similar to those of typically developing infants. However, in contrast with those of typically developing infants and infants with Down syndrome, the durational features of the prelinguistic phrases of the acochlear child were relatively unstable across development. Overall, the results indicate that audition is not necessary for the formation of prelinguistic phrasing, but hearing does influence certain aspects of prelinguistic phrasing. Based on the data obtained on this subject, typically developing infants, and infants with Down syndrome, essential characteristics of well-formed prelinguistic phrases are proposed. These are termed “canonical” phrases; their production and development may be important in the acquisition of meaningful speech.

Since the publication of the paper by the present author in 1905 on the Classification of the Phacopidae, a considerable advance has been made in our knowledge of this family as a result of further and better material being obtained, and of new discoveries in different parts of the world. Many new genera and subgenera have been instituted, and modifications or limitations of some of the old terms have been introduced by various authors. The work of Wedekind, Clarke, Rud. and E. Richter, and Kozlowski has specially dealt with questions of classification, but there is still a considerable amount of diversity in the usage and application of the generic and subgeneric names.

AbstractRecent work among the Sippar Collections of the British Musuem has brought to light a number of interesting texts, among which is the fragment BM 63570. This text lists the qīpu's of numerous temples along with other officials, associating them all with bundles of reeds measured in hundreds. This is of unusual interest, however it is not the first time such a text has come to light as a similar fragment, BM 68777, was identified and published by the present author in 1993. Indeed, without a doubt the two pieces belong to the same tablet. BM 68777 is the beginning of the text, while BM 63570 carries on the obverse from this after a very small break and then gives some lines from the top of the reverse. The reverse of BM 68777 was uninscribed.

Old Roman

Abstract A central problem in plainchant studies has been the relationship between the two “Roman” repertories, “Old Roman” (ROM) and “Gregorian” (GREG). Many attempts have been made to penetrate the “mystérieuse alchimie” that links them. Almost without exception, these have embraced the notion that ROM music was the supplier of GREG. This paper advances an alternative hypothesis. It recognizes initial transfers of ROM musical material to the Franks under Pippin III (before 768)—ROM music that was generally improvisational in process and style. However, still under Pippin or later under Charlemagne, the Franks rejected the ROM music and, in their effort to establish GREG, turned to familiar Gallican chants, which tended to have fixed, memorable melodies. Later, perhaps during the tenth century renovatio imperii under Otto I, though perhaps even during Charlemagne's reign, the authorized GREG repertory reached Rome, where it was supposed to supplant the local ROM. But the Roman musicians resisted; rather than abandon ROM, they compromised by accepting certain portions of GREG music and remodeling them so they conformed with ROM style. This sequence of events would explain the musical relationships between ROM and GREG.

Experimental Results

ABSTRACTRecent work by Lust and others has led to the prediction that children acquiring left-branching languages will exhibit a preference for backward patterns of anaphora. In this paper, we test this prediction against data from Korean and Japanese and show it to be false. An alternative hypothesis proposing a preference for forward patterns of anaphora is outlined and possible explanations for earlier experimental results supporting Lust's prediction are considered.

Matrix Semigroup

In recent work we associated a natural category to a semigroup and developed Morita theory for semigroups. In particular we gave a generalisation of Rees’ Theorem which led us to define what we call a Morita semigroup, this is our analogue of a structure matrix semigroup. In this article we formulate a method for extending Morita semigroups by groups. We say that a semigroup is an iterative Morita semigroup if it is obtained by successive applications of pasting families of Morita semigroups which have been extended by groups. By relying on Morita theory we show that every regular unambiguous semigroup is isomorphic to an iterative Morita semigroup of a special form. Our result can be viewed as a co-ordinate free version of the Synthesis Theorem.

Exact Positions

During the last twenty years many studies have been carried out in our laboratory which were aimed at establishing the exact positions of possible sharp interstellar lines of various diatomic and polyatomic molecules. In addition we have been trying to see whether the diffuse interstellar lines cannot be explained as produced by some molecule or molecular ion in the interstellar gas.The present report is a summary of our recent work in this field.

Attention is drawn to important systematic effects in the calibration procedure due to the accidental errors in the measured luminosity criteria. The present state of the luminosity calibrations in the MK system is reviewed with reference to recent work based on proper motions and radial velocities, and on trigonometric parallaxes, resulting in evidence for corrections of about −0.4 mag. for the K0–K5, III stars. Brief reference is made to the developments with regard to the Mv(K) system.The present report summarizes the principal elements of the review presented at the symposium.
