This paper provides a Distributed Morphology analysis of the paradoxical interaction of the two cases of verbal suppletion in Korean, and argues that the two suppletion types are characterized by two different types of morphological operations. The two roots found with short-form negation and honorification suggest different morphological structures: [[Neg-V] Hon] for al- ‘know’, molu- ‘not.know’, a-si- ‘know-hon’, molu-si- (not *an(i) a-si-) ‘neg know-hon’; and [Neg [V-Hon]] for iss- ‘exist’, eps- ‘not.exist’, kyey-si- ‘exist-hon’, an(i) kyey-si- (not *eps-(u)-si-) ‘neg exist-hon’. Predicate repetition constructions support the [[Neg-V] Hon] structure. In this structure, however, the negative suppletion (analyzed as fusion of negation and the root) is blocked by the honorific suffix structurally more peripheral to the root. C-command is the only requirement for context allomorphy in Distributed Morphology (Halle & Marantz 1993). Since the [+hon] feature c-commands the root, the root can show honorific suppletive allomorphy in the first cycle with negation intervening between the root and [+hon]. Negation fusion occurs in the second cycle after vocabulary insertion of the root. Fusion, then, should refer to vocabulary items, not abstract features, and will be interleaved with vocabulary insertion. If the output of the root is /kyey/ due to the honorific feature, negative suppletion will not apply and the correct form an(i) kyey-si- will be derived. Therefore, both of the distinct morphological operations for suppletion, i.e., fusion and contextual allomorphy, are necessary. The revised formulation of fusion shows that certain morphological operations follow vocabulary insertion. This derivational approach to the suppletion interaction provides support for separation of phonological and nonphonological features and for late insertion of phonological features.

The paper provides a grammatical sketch of Chitumbuka, a language widely spoken in the northern region of Malawi, and therefore used as a lingua franca in the region. The paper focuses on four key linguistic aspects of the language in its analysis. These include phonology, morphology, syntax and semantics. Data analysis followed interviews with native speakers of the language drawn from four districts of Mzimba, Rumphi, Nkhata Bay and Kasungu. There was also a significant reliance on data from published materials exploring the language. The paper agrees with available literature ascertaining the existence of 5 vowels and 27 consonant phonemes, a CV syllable structure, assimilation and strengthening processes in the language. It also shows that Chitumbuka is not a tonal language. The paper further ascertains the existence of 18 noun classes in the language and a complex verbal morphology with different types of markers for subject, object and tense. It also shows that the general sentence structure of Chitumbuka is Subject-Verb-Object with several other possible alterations. The paper ends with an exploration of loan words in the language and the realization of the notions of borrow and lend through a single lexical item.

L1 And L2

This study advances previous research about the effects of explicit instruction on second language (L2) development by examining learners’ use of verbal morphology following different types of explicit information (EI) and comprehension practice. We investigated the extent to which additional EI about L1 can reduce the effects of crosslinguistic influence in L2 oral production. Sixty-nine English-speaking learners of L2 French undertook either: (a) a ‘core’ treatment of EI about the L2 with L2 comprehension practice, (b) the same L2 core + L1comprehension practice, (c) the same L2 core + L1 comprehension practice + EI about L1, or (d) outcome tests only. Results showed that providing additional EI about the L1 benefitted the accuracy of oral production immediately after the instruction and then 6 weeks later. These results suggest that tailoring instruction, specifically the nature of the EI, to the nature of the learning problem can facilitate L2 learning. In particular, EI about L1 can facilitate L2 learning by increasing learners’ awareness of similarities and differences in how L1 and L2 express the same meanings.

On the material reconstructed derivates of proto-Slavic era a lexical-derivational taxonomy of feminine nouns with the suffix –VA is carried out. The origin and the typology of derivational suffix-va in such derivatives are established. It is proved that the suffix -VA demonstrates the ability to be combined mostly with verbal and nominal bases. Minor frequency of the creation of proto-Slavic nouns by attaching to the original foundations of the suffix -VA and different types of semantic-derivational specifics of such derivative testify in favor of assumptions about the variant of the semantic-derivational behavior of this formant, and the lack of primary word-formation functions in proto-Slavic era. It is found that the formant -VA had a distinct word-formation potential with the creation of protoSlavic nouns abstract-deverbative. In verbal morphology this particle was sometimes a marker of collectivity in nouns. In proto-Slavic era deadjectival, which are created from noun, are not uniquely identify the primary function of this suffix, since it was formed besubstantial for the representation of names of plants, household utensils, somatisms and collective nouns. Lexical-derivational typology derived from the adjective with suffix -VA is represented by two groups: the names of persons and names of animals.

The Laplace transform of the extinction time is determined for a general birth and death process with arbitrary catastrophe rate and catastrophe size distribution. It is assumed only that the birth rates satisfyλ0= 0,λj> 0 for eachj> 0, and. Necessary and sufficient conditions for certain extinction of the population are derived. The results are applied to the linear birth and death process (λj=jλ, µj=jμ) with catastrophes of several different types.

Abstract We argue that Tomasello's account overlooks important psychological distinctions between how humans judge different types of moral obligations, such as prescriptive obligations (i.e., what one should do) and proscriptive obligations (i.e., what one should not do). Specifically, evaluating these different types of obligations rests on different psychological inputs and has distinct downstream consequences for judgments of moral character.

Complete Interpretation

Previous freeze fracture results on the intact giant, amoeba Chaos carolinensis indicated the presence of a fibrillar arrangement of filaments within the cytoplasm. A complete interpretation of the three dimensional ultrastructure of these structures, and their possible role in amoeboid movement was not possible, since comparable results could not be obtained with conventional fixation of intact amoebae. Progress in interpreting the freeze fracture images of amoebae required a more thorough understanding of the different types of filaments present in amoebae, and of the ways in which they could be organized while remaining functional.The recent development of a calcium sensitive, demembranated, amoeboid model of Chaos carolinensis has made it possible to achieve a better understanding of such functional arrangements of amoeboid filaments. In these models the motility of demembranated cytoplasm can be controlled in vitro, and the chemical conditions necessary for contractility, and cytoplasmic streaming can be investigated. It is clear from these studies that “fibrils” exist in amoeboid models, and that they are capable of contracting along their length under conditions similar to those which cause contraction in vertebrate muscles.

Different Cell Types

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

Different Types

In polyethylene single crystals pairs of black and white lines spaced 700-3,000Å apart, parallel to the [100] and [010] directions, have been identified as microsector boundaries. A microsector is formed when the plane of chain folding changes over a small distance within a polymer crystal. In order for the different types of folds to accommodate at the boundary between the 2 fold domains, a staggering along the chain direction and a rotation of the chains in the plane of the boundary occurs. The black-white contrast from a microsector boundary can be explained in terms of these chain rotations. We demonstrate that microsectors can terminate within the crystal and interpret the observed terminal strain contrast in terms of a screw dislocation dipole model.

Fibers composed of different types of collagen cannot be differentiated by conventional electron microscopic stains. We are developing staining procedures aimed at identifying collagen fibers of different types.Pt(Gly-L-Met)Cl binds specifically to sulfur-containing amino acids. Different collagens have methionine (met) residues at somewhat different positions. A good correspondence has been reported between known met positions and Pt(GLM) bands in rat Type I SLS (collagen aggregates in which molecules lie adjacent to each other in exact register). We have confirmed this relationship in Type III collagen SLS (Fig. 1).
