Abstract When we couple the cyclic expansion of a probe’s domain assumed in Cyclic Agree (Rezac 2003, 2004, Béjar and Rezac 2009) with the lack of formal distinction between heads, intermediate projections, and phrases emphasized in Bare Phrase Structure (Chomsky 1995a,b) an interesting prediction arises. Maximal projections should be able to probe through the same mechanisms that allow intermediate projections to probe in familiar cases of Cyclic Agree. I argue that this prediction is borne out. I analyze agreeing adjunct C in Amahuaca (Panoan; Peru) as a maximal projection that probes its c-command domain in second cycle Agree. This account derives C’s simultaneous sensitivity to DPs within its own clause and in the clause to which it adjoins. Therefore, I conclude that Amahuaca provides evidence that maximal projections can be probes. The account also yields insight into the syntax of switch-reference in Panoan and beyond.

Formal Distinction

According to the anthropologist Mary Douglas, the quest for purity is usually accompanied by fears of change, ambiguity and transgression. Translating Douglas’ insights into historical terms, one may assume that sensibilities about what is pure and what is impure grow stronger during times of intense social and political change, as exemplifi ed by the stormy decades around 1900. This period was characterized by a profound identity-crisis and at the same time was marked by a quest for purity. One may think of a deepened concern for hygiene, of the rise of racist movements, but also of an intense longing for cultural reform and regeneration. Notwithstanding their many differences, these phenomena are linked through their concern for the formal distinction between what is pure and what is impure. A study of the work of Wagner, Bram Stoker and Zola gives some insight into the language of purity, serves to show the religious meaning of formal categories of purity and impurity, and makes it clear that the quest for purity in one area is related to the quest for purity in another area.

The Continuum

This paper examines variation in the use of copula forms and copulative structures in the Guyanese Creole (GC) continuum. A previous analysis by Bickerton (1973a, 1973b), who presented a polylectal grammar based on implicational relationships in the introduction and use of copular be, is examined in light of Labov's "principle of accountability." The primary focus of the paper is on so-called "predicate adjective" structures in basilectal GC (dipikni bin sik; dipikni a sik; dipikni go sik, and so forth) and their counterparts in the lower and mid-to-upper mesolects of the continuum {dipikni did sik; dipikni doz (bii) sik; dipikni go (bii) sik, etc.). It is argued that the range of contexts relevant to the analysis of copula variability in these structures is far wider than B's analysis accounted for. Moreover, there are substantial differences between basilectal and mesolectal varieties in phrase structure and in the organization of tense-aspect oppositions — differences overlooked in B's earlier treatment. As a result of these limitations, B's polylectal grammar provides an incomplete picture of the patterns of variation in these structures, and of the grammatical systems underlying them. The paper concludes that the claim that a polylectal grammar represents the workings of a unified system is not borne out by the evidence presented here. While an implicational scale may provide useful insight into patterns of variation and change in créole continua, the information contained in it cannot be translated directly into a synchronic grammar.

New Evidence

The proper treatment of adjuncts has been a central issue in syntactic theory since the 1980s. In the X'-theoretic analysis in the Government and Binding (GB) Theory (Chomsky 1981, 1986), they were commonly treated as optional elements attached to an intermediate or maximal projection of the head they modify. However, this treatment has been shown to be no longer tenable in the more recent Bare Phrase Structure (BPS) Theory for several conceptual reasons (Chomsky 1995: ch. 4), which renders the status of adjuncts all the more puzzling. Recently, however, Hornstein and Nunes (2008) (henceforth H&N) have proposed a new theory of adjuncts that conforms to the precepts of the BPS. It proposes that adjuncts need not be labeled for purposes of syntactic computation in contrast to complements and specifiers, which require the result of concatenation to be labeled. This squib presents new evidence for H&N's theory from one-replacement.

ABSTRACTThis paper models maximum entropy configurations of idealized gravitational ring systems. Such configurations are of interest because systems generally evolve toward an ultimate state of maximum randomness. For simplicity, attention is confined to ultimate states for which interparticle interactions are no longer of first order importance. The planets, in their orbits about the sun, are one example of such a ring system. The extent to which the present approximation yields insight into ring systems such as Saturn's is explored briefly.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

Insight Into

The synaptic connections in cat retina that link photoreceptors to ganglion cells have been analyzed quantitatively. Our approach has been to prepare serial, ultrathin sections and photograph en montage at low magnification (˜2000X) in the electron microscope. Six series, 100-300 sections long, have been prepared over the last decade. They derive from different cats but always from the same region of retina, about one degree from the center of the visual axis. The material has been analyzed by reconstructing adjacent neurons in each array and then identifying systematically the synaptic connections between arrays. Most reconstructions were done manually by tracing the outlines of processes in successive sections onto acetate sheets aligned on a cartoonist's jig. The tracings were then digitized, stacked by computer, and printed with the hidden lines removed. The results have provided rather than the usual one-dimensional account of pathways, a three-dimensional account of circuits. From this has emerged insight into the functional architecture.

One of the major materials problems encountered in the development of fast breeder reactors for commercial power generation is the phenomenon of swelling in core structural components and fuel cladding. This volume expansion, which is due to the retention of lattice vacancies by agglomeration into large polyhedral clusters (voids), may amount to ten percent or greater at goal fluences in some austenitic stainless steels. From a design standpoint, this is an undesirable situation, and it is necessary to obtain experimental confirmation that such excessive volume expansion will not occur in materials selected for core applications in the Fast Flux Test Facility, the prototypic LMFBR now under construction at the Hanford Engineering Development Laboratory (HEDL). The HEDL JEM-1000 1 MeV electron microscope is being used to provide an insight into trends of radiation damage accumulation in stainless steels, since it is possible to produce atom displacements at an accelerated rate with 1 MeV electrons, while the specimen is under continuous observation.

Scanning Electron

Occasionally in history, an event may occur which has a profound influence on a technology. Such an event occurred when the scanning electron microscope became commercially available to industry in the mid 60's. Semiconductors were being increasingly used in high-reliability space and military applications both because of their small volume but, also, because of their inherent reliability. However, they did fail, both early in life and sometimes in middle or old age. Why they failed and how to prevent failure or prolong “useful life” was a worry which resulted in a blossoming of sophisticated failure analysis laboratories across the country. By 1966, the ability to build small structure integrated circuits was forging well ahead of techniques available to dissect and analyze these same failures. The arrival of the scanning electron microscope gave these analysts a new insight into failure mechanisms.

The electric and thermal properties of the resistor material in an automotive spark plug should be stable during its service lifetime. Containing many elements and many phases, this material has a very complex microstructure. Elemental mapping with an electron microprobe can reveal the distribution of all relevant elements throughout the sample. In this work, it is demonstrated that the charge-up effect, which would distort an electron image and, therefore, is normally to be avoided in an electron imaging work, could be used to advantage to reveal conductive and resistive zones in a sample. Its combination with elemental mapping can provide valuable insight into the underlying conductivity mechanism of the resistor.This work was performed in a CAMECA SX-50 microprobe. The spark plug used in the present report was a commercial product taken from the shelf. It was sectioned to expose the cross section of the resistor. The resistor was known not to contain the precious metal Au as checked on the carbon coated sample. The sample was then stripped of carbon coating and re-coated with Au.
