Dutch dialects show an enormous amount of variation with respect to the verbal inflectional paradigm. To wit, some dialects only have two forms in the present tense indicative to express all persons in singular and plural, whereas other dialects use three or even four different forms to do so. inflectional pattern is equally likely to occur; some patterns are found nowhere, whereas others are geographically widespread and stable over time. We will show that these recurring patterns of syncretism are also typologically well-attested. The recurring pattern involves neutralization of a morphosyntactic distinction in the marked half of the paradigm. More specifically, we see that plural and past tense are neutralizing contexts. We will show that a grammar that solely uses underspecification of affixes to account for the observed syncretisms, misses a generalization that can only be expressed by impoverishment rules or some paradigmatic means.  相似文献

The inventories of subject clitics in northern Italian varieties are affected by widespread morphological changes. One of these changes is syncretism. In addition, many dialects display defective paradigms where some of the clitics are missing. The clitics that undergo syncretism and the clitics that are missing tend to be the same: the first person singular and plural, the second plural, and, less frequently, the third plural. Working in the framework of Distributed Morphology, I argue that these clitics are the target of markedness constraints that trigger repair operations leading to either syncretism or the removal of forms from a paradigm. In particular, I propose two such operations: one is feature deletion, which deletes a marked feature specification. This operation is always followed by feature insertion, which inserts the opposite value of the deleted feature specification (this operation leads to syncretism). The other one is obliteration, which deletes a morphosyntactic node and leads to underspecified morphosyntactic representations (this operation leads to paradigmatic gaps). I investigate how these operations affect the morphological exponents in PF, creating syncretisms and gaps in exponence.  相似文献

The aim of this paper is to make sense of the typologically quite exceptional pattern of person neutralization in the plural as we find it in Dutch verbal paradigms. We argue that Dutch, and most of its dialects, have a structural pattern of syncretism in their verbal paradigm: there are no person-distinctions in the plural. The main question of this paper is: where does this structural pattern of neutralization in Dutch come from, if we cannot explain it as a typologically wellattested pattern? As a first step, note that although the pattern is typologically quite odd, it conforms to another well-known generalization about paradigms: neutralization occurs in the marked half of the paradigm (see e.g. Nevins 2009). Further, we need to explain why this pattern occurs precisely in the Netherlands at this particular point in time. To this, we argue that this pattern arises as the result of a particular language acquisition strategy together with reduced evidence from the input for the fully inflected forms, probably as a result of dialect contact. This reduced evidence causes the third person, being the most frequent form, to dominate the other plural forms. In combination with limited paradigm splitting (Pinker, 1996), this explains the uniform plural that we find in most Dutch dialects.  相似文献

This study examines some cases of heteroclisis in the history of Romanian dialects, and concludes that the data call for a reconsideration of Stump’s distinction (Language 82:279–322, 2006) between ‘cloven’ heteroclisis, where the intraparadigmatic ‘split’ is aligned with some morphosyntactic feature distinction, and ‘fractured’ heteroclisis, where this is not the case and the pattern of heteroclisis is purely morphological. Stump’s account creates the impression that the ‘cloven’ variety is universally predominant, and that the ‘fractured’ variety tends to follow very closely the available ‘cloven’ patterns of the language. I shall suggest, instead, that the ‘fractured-only’ situation may in fact underlie heteroclisis cross-linguistically, the phenomenon being in general sensitive not directly to morphosyntactic content, but rather to characteristic, and often purely ‘morphomic’, patterns of stem-allomorphy. Research for this paper was undertaken as part of the Arts and Humantities Research Council-funded project Autonomous Morphology in Diachrony: comparative evidence from the Romance Languages, currently being conducted at Oxford University.  相似文献

This paper explores the syncretic accommodations made by North Mekeo (PNG) villagers arising from recent historical encounters with Catholic (Sacred Heart) missionaries over issues of ritual authenticity and effectiveness, personhood, and agency in a wider field of Christian evangelism and globalisation. Through a careful examination and comparison of pre‐existing ritual notions and practices (e.g., sorcery techniques, mortuary ritual performance, gender rituals) and the recent trends of commodification and enthusiastic Catholic charismatic performance, what might appear to be incongruous religious beliefs and practices are shown to possess numerous remarkably compatible similarities at the level of explicit cultural categorisation and ritual enactment. In accord with long‐standing anthropological arguments, recent North Mekeo syncretism thus consists of an integrated, albeit transformed rather than ‘confused’, mixing of indigenous and exogenous religious elements. Further, in this analysis of recent Melanesian religious change syncretism implies a novel conceptual convergence between syncretic processes and the dynamics of personhood, sociality and agency as construed in the framework of the ‘new Melanesian ethnography’.  相似文献

For many years the evolution of language has been seen as a disreputable topic, mired in fanciful “just so stories” about language origins. However, in the last decade a new synthesis of modern linguistics, cognitive neuroscience and neo-Darwinian evolutionary theory has begun to make important contributions to our understanding of the biology and evolution of language. I review some of this recent progress, focusing on the value of the comparative method, which uses data from animal species to draw inferences about language evolution. Discussing speech first, I show how data concerning a wide variety of species, from monkeys to birds, can increase our understanding of the anatomical and neural mechanisms underlying human spoken language, and how bird and whale song provide insights into the ultimate evolutionary function of language. I discuss the “descended larynx” of humans, a peculiar adaptation for speech that has received much attention in the past, which despite earlier claims is not uniquely human. Then I will turn to the neural mechanisms underlying spoken language, pointing out the difficulties animals apparently experience in perceiving hierarchical structure in sounds, and stressing the importance of vocal imitation in the evolution of a spoken language. Turning to ultimate function, I suggest that communication among kin (especially between parents and offspring) played a crucial but neglected role in driving language evolution. Finally, I briefly discuss phylogeny, discussing hypotheses that offer plausible routes to human language from a non-linguistic chimp-like ancestor. I conclude that comparative data from living animals will be key to developing a richer, more interdisciplinary understanding of our most distinctively human trait: language.  相似文献

Background

Bone morphogenetic proteins regulate multiple processes in embryonic development, including early dorso-ventral patterning and neural crest development. BMPs activate heteromeric receptor complexes consisting of type I and type II receptor-serine/threonine kinases. BMP receptors Ia and Ib, also known as ALK3 and ALK6 respectively, are the most common type I receptors that likely mediate most BMP signaling events. Since early expression patterns and functions in Xenopus laevis development have not been described, we have addressed these questions in the present study.

Results

Here we have analyzed the temporal and spatial expression patterns of ALK3 and ALK6; we have also carried out loss-of-function studies to define the function of these receptors in early Xenopus development. We detected both redundant and non-redundant roles of ALK3 and ALK6 in dorso-ventral patterning. From late gastrula stages onwards, their expression patterns diverged, which correlated with a specific, non-redundant requirement of ALK6 in post-gastrula neural crest cells. ALK6 was essential for induction of neural crest cell fate and further development of the neural crest and its derivatives.

Conclusions

ALK3 and ALK6 both contribute to the gene regulatory network that regulates dorso-ventral patterning; they play partially overlapping and partially non-redundant roles in this process. ALK3 and ALK6 are independently required for the spatially restricted activation of BMP signaling and msx2 upregulation at the neural plate border, whereas in post-gastrula development ALK6 exerts a highly specific, conserved function in neural crest development.

Morphological features characterize variations in morphological form which are independent of syntactic context. They contrast with morphosyntactic features, which characterize variations in form correlated with different syntactic contexts. Morphological features account for formal variation across lexemes (inflectional class), as well as morphosyntactically incoherent alternations within the paradigm of a single lexeme. Such morphological features are not available to the syntax, as is made explicit in the principle of ‘morphology-free syntax’. Building on work on stress patterns in Network Morphology and on stems in Paradigm Function Morphology, we take initial steps towards a typology of these morphological features. We identify four types: inflectional class features (affixal and prosodic), stem indexing features, syncretic index features and morphophonological features. Then we offer a first list of criteria for distinguishing them from morphosyntactic features (independently of the principle of morphology-free syntax). Finally we review the arguments demonstrating the need to recognize morphological features.  相似文献

This paper addresses the question of how certain kinds of overlapping syncretisms in inflectional paradigms can be accounted for that Baerman et al. (Language 80:807–824, 2005) refer to as convergent/divergent bidirectional syncretisms (based on earlier work by Stump, Inflectional morphology, 2001). Bidirectional syncretism strongly resists accounts in terms of standard rules of exponence (or similar devices) that correlate inflection markers with (often underspecified) morpho-syntactic specifications (such rules are used in many morphological theories; e.g., Anderson, A-morphous morphology, 1992; Halle and Marantz in The view from building, pp. 111–176, 1993; Aronoff, Morphology by itself, 1994; Wunderlich in Yearbook of morphology 1995, pp. 93–114, 1996; and Stump, Inflectional morphology, 2001). The reason is that it is difficult to capture overlapping distributions by natural classes. In view of this, rules of referral have been proposed to derive bidirectional syncretism (Stump, Inflectional morphology, 2001; Baerman et al. (Language 80:807–824, 2005)). In contrast, I would like to pursue the hypothesis that systematic instances of overlapping syncretism ultimately motivate a new approach to inflectional morphology—one that fully dispenses with the assumption that morphological exponents are paired with morpho-syntactic feature specifications (and that therefore qualifies as radically non-morphemic): First, rules of exponence are replaced with feature co-occurrence restrictions (FCRs; Gazdar et al., Generalized Phrase Structure Grammar, 1985). For phonologically determined natural classes of exponents, FCRs state incompatibilites with morpho-syntactic feature specifications. Second, marker competition is resolved by a principle of Phonology-driven Marker Selection (PMS). PMS takes over the role of the Specificity (Blocking, Elsewhere, Panini) Principle of standard analyses. Empirically, the main focus is on Bonan declension; the analysis is subsequently extended to Gujarati conjugation and Latin o-declension, with further remarks on bidirectional syncretism in other inflectional paradigms.  相似文献

Autumn migration routes of two Dutch female Montagu’s Harriers (Circus pygargus) were documented for the first time using satellite telemetry. Both migrated to their African wintering area—one via the Straits of Gibraltar through the Mediterranean and the other via Italy/Tunisia. The rate of travel was comparable to values reported for larger raptor species.  相似文献

This article draws from three ethnographic studies of children playing sociodramatically in multilingual, multicultural contexts. Countering a deficit perspective that focuses on what children from nondominant cultures do not know, we use the concept of syncretism to illuminate children's expertise and intentionality as they blend knowledge from multiple worlds to reinvent cultural practices and create new spaces for learning. Findings encourage educators to learn from the syncretic nature of children's teaching and learning through play.  相似文献

The author's theory of the adoption of certain types of behavior patterns (Rashevsky, N., 1957, “Contributions to the Theory Initiative Behavior”.Bull. Maths. Biophysics,19, 91–119; 1968,Looking at History through Mathematics, Cambridge, Massachusetts: M.I.T. Press) consisting of elementary behaviors for each of which there is an opposite one and the two are mutually exclusive, is applied to describe the changes in the general type of behavior of a society. The elementary acts of which the whole problem consists may be either overt activities or beliefs or opinions. The general behavior patternsadopted by the society are considered as the “proper” or “just” ones. Any deviation from it in either one or more of the component elementary behaviors is considered as “unjust” and is subject to some punitive action. The total number of possible mutually exclusive behavior patterns is very large but finite. Within this very large range of possible patterns, we find that this notion of justice is relative, because changes from any behavior pattern to any other may occur. It is further shown that the amount of punishment for the deviation from the accepted pattern in order to be effective as well as efficient must be applied in different ways to different individuals even for the same transgression.  相似文献

Understanding the molecular mechanisms underlying bone development is a fundamental and fascinating problem in developmental biology, with significant medical implications. Here, we have identified the expression patterns for 36 genes that were characteristic or dominant in the consecutive cell differentiation zones (mesenchyme, precartilage, cartilage) of the tip section of the developing velvet antler of red deer Cervus elaphus. Two major functional groups of these genes clearly outlined: six genes linked to high metabolic demand and other five to tumor biology. Our study demonstrates the advantages of the antler as a source of mesenchymal markers, for distinguishing precartilage and cartilage by different gene expression patterns and for identifying genes involved in the robust bone development, a striking feature of the growing antler. Putative roles for “antler” genes that encode α-tropomyosine (tpm1), transgelin (tagln), annexin 2 (anxa2), phosphatidylethanolamine-binding protein (pebp) and apolipoprotein D (apoD) in intense but still controlled tissue proliferation are discussed.  相似文献

This article analyzes the grammaticalization of adjectives into prefixes in Dutch and French. In the first part, the notion of ‘affixoids’, hybrid elements that combine properties of free lexemes and bound morphemes, will be defined and illustrated. It will be claimed that affixoids can be seen as a result of a grammaticalization process for which we will advance phonological, morphological, semantic and distributional parameters applying to the evolution of adjectives into prefixes. The second part will be devoted to a specific case study in which these grammaticalization parameters will be applied to the Dutch adjectives oud ‘old’ and nieuw ‘new’ and their French counterparts ancien ‘old’ and nouveau ‘new’ when used in word-formation. More particularly, we will examine whether these adjectives may develop prefix-like properties when embedded in a compound structure and determine their degree of grammaticalization.

Cambridge Composite Cross Five (CCV) of barley was studied utilising hordeins, restriction fragment length polymorphisms (RFLPs) and reaction to powdery mildew with a view to understanding the genetic changes occurring in the population. Changes in the frequency of individual hordein patterns as well as pattern combinations showed directional trends in successive generations in three parallel populations maintained as discrete populations since 1977 in Cambridge. Certain hordein pattern combinations were more common in the resistance classes and there was a strong association between hordein patterns and mildew reaction. RFLP analysis revealed that 80% of a random sample taken from generation F24 of Population I had the same restriction pattern as that of the cultivar Algerian, which was one of the original 30 parental lines of CCV. This cultivar is the source of the Mla1 allele in barley improvement programmes in Europe. We argue, based on supporting evidence from hordein analysis and tests of reaction to selected mildew isolates of known virulence isolates together with UK virulence surveys, that selection for Mla1 in Cambridge has been the predominant evolutionary force in CCV in Cambridge.  相似文献

Specific karyotype structure and chromosomal polymorphism was investigated in the populations of Sergentia nebulosa Linevitsh et al., 1984 and Sergentia assimilis Proviz V. et Proviz L., 1999, the deep-water endemic chironomid species (Diptera, Chironomidae) from the Baikal Lake. The distinguishing feature of the karyotypes of these species, compared to the other Baikalian Sergentia, is well-developed nucleolus in region 6 of arm C. Both species display the presence of interspecific population polymorphism, determined by the structure of this arm. In some populations, chromosome regions from 4 to 6 contain a homozygous inversion, which is absent in the other populations. The distinguishing karyotype feature of S. assimilis, which shares fluctuating homozygous inversions with the other species, is the presence of two species-specific homozygous inversions. These are the secondary overlapping inversion in arm A, regions 2 to 7, and the inversion in regions 4 to 10 of arm G. Both species of interest contain nucleolus organizer in region 10 of arm G. In populations of S. nebulosa, six heterozygous inversions localized in arms A, B, C, F, and G were discovered. The highest number of heterozygotes for inversions (71%) was observed in the population from Southern Baikal. In arm B of S. assimilis, one heterozygous inversion and heterozygosity for nucleolus organizer in the chromosome region 16 was detected. Chromosomal evolution of Baikalian Sergentia, and the role of inversion polymorphism in the population adaptation is discussed. Original Russian Text ? V.I.

Recent work in linguistic anthropology highlights the role of linguistic ideologies, or cultural conceptions of language, in transforming social relations and linguistic structure and use. This article examines the links between language attitudes and uses in their institutional and interactional contexts on Rapa Nui, a Polynesian island community that is part of the Chilean nation-state. By the 1970s, a sociolinguistic hierarchy and functional compartmentalization of languages between Spanish and Rapa Nui—what I will describe as "colonial diglossia"—had become established in the community, which was rapidly becoming bilingual. Language shift toward Spanish has continued to advance since then. However, rising Rapa Nui syncretic language practice and consciousness, combined with the political successes of a local indigenous movement and changes in the local economy, are now contributing to the breakdown of colonial diglossia, generating better conditions for the maintenance of the Rapa Nui language.  相似文献
