This chapter furnishes additional support for the Anti-contiguity theory of wh- prosody by demonstrating that it derives two surprising and mysterious asymmetries of Nupe wh- syntax. The first asymmetry concerns the fact that in embedded clauses the structurally lowest wh- item in a multiple wh- question may not appear in-situ. The second asymmetry concerns the availability of embedded non-interrogative focus and the impossibility of embedded interrogative focus. Both of these asymmetries are argued to be explainable in terms of the Anti-contiguity ban on contiguous wh- phrasing with overt C at the Intonational Phrase level, given that overt embedded C does not introduce an Intonational Phrase boundary in Nupe, as in Wasa and Asante Twi. As a consequence, no Intonational Phrase boundary insulates focused embedded wh- items from overt embedding complementizers, therefore running afoul of the Anti-contiguity prohibition.

This chapter develops the Anti-contiguity proposal based on the distribution of wh- in-situ in Krachi, Bono, Wasa, and Asante Twi. Embedded wh- in-situ is only allowed in Krachi and Bono. The chapter argues that a prohibition on wh- items phrasing with overt C at the level of Intonational Phrase (iP) underpins this distributional asymmetry. In these languages, the acceptability of embedded wh- in-situ correlates with the prosodic status of the immediately containing clause—embedded clauses are independent iPs in Krachi and Bono, but not in Wasa and Asante Twi. Thus, iP boundaries divide C from embedded interrogatives in Krachi and Bono, preventing the items from forming iP constituents. No such boundaries intervene between embedded C and wh- in Wasa and Asante Twi, yielding prosodic mappings in which the items phrase together. Consequently, embedded wh- in-situ is prosodically licit in Krachi and Bono, but not in Wasa or Asante Twi.

The Southwestern (Oghuz) branch of Turkic consists of languages that are largely mutually intelligible, and are similar with respect to their structural properties. Because Turkish is the most prominent member of this branch with respect to number of speakers, and because it is the best-studied language in this group, this chapter describes modern standard Turkish as the representative of that branch and limits itself to describing Turkish. The morphology of Oghuz languages is agglutinative and suffixing; their phonology has vowel harmony for the features of backness and rounding; their basic word order is SOV, but most are quite free in their word order and are wh-in-situ languages; their relative clauses exhibit gaps corresponding to the clause-external head, and most embedded clauses are nominalized. Fully verbal embedded clauses are found, too. The lexicon, while largely Turkic, also has borrowings from Arabic, Persian, French, English, and Modern Greek and Italian.

Semantic Properties

Natural language allows questioning into embedded clauses. One strategy for doing so involves structures like the following: [CP-1 whi [TP DP V [CP-2 … ti …]]], where a wh-phrase that thematically belongs to the embedded clause appears in the matrix scope position. A possible answer to such a question must specify values for the fronted wh-phrase. This is the extraction strategy seen in languages like English. An alternative strategy involves a structure in which there is a distinct wh-phrase in the matrix clause. It is manifested in two types of structures. One is a close analog of extraction, but for the extra wh-phrase: [CP-1 whi [TP DP V [CP-2 whj [TP…t­j­…]]]]. The other simply juxtaposes two questions, rather than syntactically subordinating the second one: [CP-3 [CP-1 whi [TP…]] [CP-2 whj [TP…]]]. In both versions of the second strategy, the wh-phrase in CP-1 is invariant, typically corresponding to the wh-phrase used to question propositional arguments. There is no restriction on the type or number of wh-phrases in CP-2. Possible answers must specify values for all the wh-phrases in CP-2. This strategy is variously known as scope marking, partial wh movement or expletive wh questions. Both strategies can occur in the same language. German, for example, instantiates all three possibilities: extraction, subordinated, as well as sequential scope marking. The scope marking strategy is also manifested in in-situ languages. Scope marking has been subjected to 30 years of research and much is known at this time about its syntactic and semantic properties. Its pragmatics properties, however, are relatively under-studied. The acquisition of scope marking, in relation to extraction, is another area of ongoing research. One of the reasons why scope marking has intrigued linguists is because it seems to defy central tenets about the nature of wh scope taking. For example, it presents an apparent mismatch between the number of wh expressions in the question and the number of expressions whose values are specified in the answer. It poses a challenge for our understanding of how syntactic structure feeds semantic interpretation and how alternative strategies with similar functions relate to each other.

Two Populations

Two populations of the diploid and 10 populations of the tetraploid cytotype of Hordeum marinum ssp. gussoneanum were studied for the presence of chromosomal segments harbouring rDNA. Conventional cytological methods established the presence of only one satellited (SAT) chromosome pair in both cytotypes. This was supported by silver staining revealing two NORs and two standard-sized nucleoli. Two additional micronucleoli were observed in a few interphases of two tetraploid populations indicating the presence of an extra chromosome pair with very low nucleolus-forming activity. In situ hybridization with the wheat rDNA probe pTA71 identified intense signals at the nucleolar constrictions of the SAT chromosomes of both cytotypes and weaker signals in a chromosome pair of the tetraploid cytotype, morphologically similar to the SAT chromosomes but without visible nucleolar constrictions. This confirms the presence of rDNA in two chromosome pairs in the tetraploid cytotype. The morphological similarity between these two pairs and the SAT-chromosome pair of the diploid cytotype as well as an identical position of the signals in all three pairs give additional support to an autoploid origin of the tetraploid cytotype. The rDNA at the nucleolar constrictions consisted of two segments of condensed rDNA of different sizes connected by diffuse rDNA. The rDNA of the chromosome pair without nucleolar constrictions was condensed supporting that this conformation is connected with inactivity. The tripartite structure of the rDNA at the nucleolar constrictions corresponds to similar tripartite structures observed after silver staining and Giemsa C-banding.Key words: in situ hybridization, rDNA location, Hordeum marinum, autoploidy, inactive NORs.

In October 2000 the Mississippi Department of Transportation (MDOT) initiated a study to evaluate the long-term performance of lime–fly ash (LFA) stabilized soil as a base course material. This study entailed performing falling weight deflectometer (FWD) tests on both newer and older pavements and coring pavement at each FWD location to observe the condition of the layers, to obtain pavement thicknesses, and to perform unconfined compressive strength (UCS) testing. Visual observation, backcalculated modulus, and in situ structural layer coefficient values showed that MDOT LFA-stabilized soil base courses have highly variable material properties and thicknesses. Recommendations were made to increase the average LFA material property values and to reduce the spread in these values by increasing the required compaction of the LFA-stabilized soil base layer to 100% standard Proctor effort, setting the required in situ Proctor UCS at 400 psi, and reducing variability by either improving the current method of field-mixed-in-place stabilization or requiring plant-mixed material with placement of the blended material via a paver. It is further recommended to increase the typical LFA-stabilized soil base layer design thickness from 6 to 8 in. and to use a 6-in. chemically stabilized subgrade layer to provide additional support to the pavement structure.

Cell Harvest

The specificity of anti-lymphocyte globulin (ALG) has been used to analyze an immune mechanism which is mediated by immunologically committed lymphoid cells to the apparent exclusion of humoral antibody. Rabbit antimouse lymphocyte globulin completely suppressed the immunity which can be passively transferred with Listeria-immune lymphoid cells from actively infected donors. When prospective donors were given a single dose of 1.0 mg of ALG, it remained active against immune lymphoid cells transferred 24 hr later; yet immune cells in the spleens of donors could not be inactivated in situ by even larger doses of ALG given 24 hr prior to cell harvest. In keeping with this finding, the immunity to reinfection with Listeria was not suppressed by a single dose of ALG, indicating that the immunologically active cells in the spleen are not accessible to intravenously administered ALG. On the other hand, protracted treatment with ALG did abolish most of the memory of a previous infection in intact animals. From this and other evidence, it was concluded that immunologically committed cells are vulnerable to attack by ALG only if they circulate. While in circulation, they make contact both with ALG and the phagocytic elements of the reticuloendothelial system which appear to be responsible for their destruction. Four lines of evidence indicated that the suppression of anti-Listeria resistance with ALG depends upon destruction of immune lymphoid cells and not to any action it has on host macrophages. It is possible to infer from this that immunity to L. monocytogenes depends upon a two cell system in which the donor lymphoid cells provide the immunological reactivity to the organism and recipient macrophages provide the mechanism through which resistance is expressed. Accompanying papers provide additional support for this view, and reasons for believing that delayed-type hypersensitivity and acquired cellular resistance are mediated by the same population of immunologically committed lymphoid cells.

A unique find of a partial egg in contact with articulated gastralia from a known specimen of the dromaeosaurid Deinonychus antirrhopus (AMNH 3015) is described. Much of the original taphonomic context of the specimen was lost during the 1931 excavation and preparation, but enough information is preserved to provide strong evidence for a parental association between the adult skeleton and egg. The articulated nature of the gastralia suggests that the adult skeleton was at least partially articulated and had not suffered from either extensive subaerial exposure or postmortem transport, and the egg preservation also indicates in situ burial and postburial lithogenic crushing. Additional support stems from the presence of limey claystone matrix that indicates a low-energy depositional event. Phylogenetic characteristics of the eggshell microstructure are consistent with a theropod origin, and skeletochronological analysis suggests that AMNH 3015 was an adult and thus of breeding age bolstering the interpretation that the egg derives from the skeletal specimen. Physiological parameters of D. antirrhopus, such as estimated mass and pelvic canal diameter, as well as eggshell thickness, are very similar to the similar sized and closely related oviraptorid Citipati osmolskae. Closely related maniraptoran theropods of several species have been found brooding their nests with the gastralia close to or in contact with eggs, and such a scenario is consistent with the preservation of AMNH 3015. Alternative explanations to a parental association, such as random co-occurrence or feeding, are improbable given the taphonomic and biological data of the find. AMNH 3015, therefore, probably represents the first identifiable dromaeosaurid egg yet discovered. It shares derived characters such as two eggshell layers with other theropods. Within theropods, the AMNH 3015 eggshell shares derived characteristics with oviraptorids and differs from troodontid eggshell despite the fact that these taxa are often recovered as sister groups in analyses of skeletal characters, but this signal is weak.

This paper offers basic observations about wh-questions in JSL with clause-final wh-signs, i.e., wh-finals. Basic word order of matrix wh-sentences in Japanese Sign Language (JSL) have been reported by previous studies such as Morgan (2006), Fischer and Gong (2010), Kimura (2011), and Akahori and Oka (2011), among others, which reported that wh-signs can appear in the clause-final position in addition to clause-initial and in-situ positions. In order to investigate the syntactic mechanism of JSL wh-constructions, it is also necessary to confirm basic syntactic properties of wh-signs in embedded clauses. However, distributions of wh-signs in embedded clauses have not been fully investigated in previous studies. Based on the discussion on the word order of sentences with direct and indirect speech in JSL in Uchibori et al. (2011), this paper demonstrates that wh-signs occur in embedded clauses that are not instances of direct speech (or quotations) of wh-questions, but those of syntactically embedded indirect speech. In embedded clauses, wh-finals appear as in the matrix wh-questions. Relevant theoretical issues are discussed concerning the relation between linear properties (i.e., distributions of wh-expressions) and the structural properties of natural language.

In English, auxiliaries form a cohesive category—unlike main verbs, they all raise to T. In Danish, it is not so obvious that auxiliaries form such a unified category. In root clauses, all verbal elements can raise to T (and then to C), while in embedded clauses they always stay in situ. Therefore, determining the position of a verbal element in the extended verbal projection is a challenging task. We examine the Danish verbal elementg⊘re‘do’ that shows up when the verb phrase has been topicalized, elided, or pronominalized. Even though on the surfaceg⊘remight appear to be of category T or v, we argue that it is located right in the middle. We argue that it is an auxiliary, but, unlike other auxiliaries,g⊘reis defective because it only subcategorizes for vPs that are pronominal.*

Insight Into

Fgf6, a member of the Fibroblast Growth Factor (FGF) family, is developmentally regulated and its expression is highly restricted in the adult. To gain further insight into the role of Fgf6, we studied its expression during embryogenesis using RNA in situ hybridization. Fgf6 expression is restricted to developing skeletal muscle. Fgf6 transcripts are first detected in the somites at 9.5 days post-conceptus, and expression continues in developing skeletal muscles up to at least 16.5 days post-conceptus. Fgfr4 is a putative receptor for FGF6. Its pattern of expression during myogenesis overlaps that of Fgf6, but both genes are not expressed in exactly the same population of cells. In addition, recombinant FGF6 protein is able to repress the terminal differentiation of myoblasts in culture, providing additional support to the concept that FGF6 plays an important role in myogenesis.
