Abstract A group of Arabic dialects in Yemen exhibit a velar k in the subject suffixes of the perfect paradigm. The 1sg subject suffix surfaces in the various dialects as -ku, -k or -kw. In addition, the vocalization of the base may or may not be colored with a round vocalic quality, depending on both the realization of the suffix and the verbal type faʿal or fiʿil. Based on inquiries among speakers from Lower Yemen, we propose a path of evolution that leads from -ku to the labialized -kw, to a “colored” stem, and finally to the grammaticalization of coloration and loss of labialization. Two pressures propel the passage between stages: a functional pressure to distinguish between 1sg and 2msg, and a phonological pressure to avoid monopositional final vowels. The phonological pressure is shown to also motivate palatalization in the 2fsg -ki ⇒ -ky (⇒ -š), as well as the effect of pre-pausal nasal insertion, viz. -ku ⇒ -kum# and -ki ⇒ -kiŋ#. We further show that final vowels resulting from the interaction of the subject suffixes with object clitics are phonologically long—even if phonetically neutralized—and hence they do not violate the phonological requirement. The formal theories of strict CV (Lowenstamm 1996, Scheer 2004) and Element Theory (Kaye et al. 1985) are used to explain the a-synchronized development in the different verbal patterns, as well as the extent of the phonological ban on monopositional vowels.

Summary The paper deals with a few aspects of the morphosyntax of clitics in Piedmontese (Western Romance) and their historical development. In Piedmontese an element =l= (orthographically l’) is obligatorily inserted between the Subject Clitics and all and only the inflected forms of “to have”; in several varieties of Piedmontese this element has a double interpretation synchronically, either as a semantically null element or as an Object Clitic of 3rd singular. Although the presence of such an element is not rare among neighboring Romance varieties, where it generally acts as a 3rd singular subject clitic, it is argued that in Piedmontese its peculiar distribution is intimately tied to other unusual morphosyntactic features, all of them having developed within the last two-to-three centuries. In particular, historical reanalysis of l’ was crucial in the positioning of the object clitics after the participle in compound verbal forms (a rare pattern among Romance languages). Partially correcting traditional analyses (such as Meyer-Lübke 1900), it is argued that the necessity to avoid ambiguity and clearly identify a pronominal object was at best a contributing factor in triggering morphological change. The postpositioning of the object clitics was rather mainly the result of the extension in use of the subject clitics, and of the ensuing reanalysis of the element l’. This was made possible by two conditions: a restricted set of occurrences in which l’ was found, and a ready-made alternative interpretation. Comparison with neighboring varieties shows that such a development was not possible in those Romance languages which did not have an element similar to l’ in the restricted range of uses of premodern Piedmontese. Résumé Cet article traite de quelques aspects de la morphologie des clitiques en piémontais (une langue romane occidentale) et de leur développement historique. On trouve en piémontais un élément =l= (l’ dans l’orthographe) obligatoirement inséré entre les clitiques du sujet et les formes fléchies du verb ‘avoir’. Dans plusieurs variétés du piémontais cet élément peut être interprété soit comme un élément sémantiquement vide, soit comme le clitique objet de la troisième personne singulier. Bien que la présence d’un élément similaire au l’ piémontais n’est pas rare parmi les variétés voisines (où il joue généralement le rôle de clitique sujet de la troisième personne singulière), l’article démontre que la distribution inhabituelle de cet élément en piémontais est étroitement liée à un certain nombre d’autres particularités morphosyntactiques qui se sont toutes développés durant les deux ou trois derniers siècles. En particulier, la réanalyse historique de l’élément l’ a été décisive pour le positionnement des clitiques objet après le participe dans les temps composés — une solution fort rare parmi les langues romanes. Avec une révision partielle des analyses traditionelles (par ex. Meyer-Lübke 1900), on démontre que la nécessité d’éviter toute ambiguïté et de distinguer clairement un objet pronominal a joué tout au plus un rôle complémentaire dans le changement morphologique. Le positionnement des clitiques object après le participe a été plutôt le résultat d’une extension de l’usage des clitiques sujet, ce qui a amené à une réanalyse de l’élément l’. Cette réanalyse a été permise par deux conditions: une distribution fort limitée de l’ et la possibilité de l’amener à une analyse alternative. La comparaison avec les variétés voisines démontre que le même développement qu’on trouve en piémontais ne s’est pas produit dans ces langues romanes qui étaient dépourvues d’un élément comparable à l’ dans les domaines d’usage bien limités qu’on trouvait en piémontais pré-moderne. Zusammenfassung Dieser Artikel befaßt sich mit einigen Aspekten der Morphosyntax von Klitika im Piedmontesischen (Westromanisch) und mit ihrer historischen Entwicklung. Im Piedmontesichen ist es obligatorisch, ein Element =l= (ortographisch l’) zwischen Subjektsklitika und allen flektierten Formen (und nur diesen) des Verbs ‘haben’ einzufügen. In manchen Mundarten des Piedmontesischen ist dieses Element in zweifacherweise interpretierbar, und zwar entweder als semantisch leeres Element oder als Objektklitikum der 3. Person Singular. Obgleich das Element selbst in benachbarten romanischen Varietäten nicht selten vorkommt und dort im allgemeinen als Klitikum der 3. Person Singular fungiert, wird hier argumentiert, daß seine eigenartige Distribution im Piedmontesischen in engem Zusammenhang mit anderen ungewöhnlichen morphosyntaktischen Phänomenen steht, die sich allesamt innerhalb der letzten zwei bis drei Jahrhunderte entwickelt haben. Insbesondere war eine historische Reanalyse des Elements l’ entscheidend für die Position von Objektsklitika nach dem Partizip in zusammengesetzten Verbformen, was in romanischen Sprachen selten vorkommt. Dieser Artikel berichtigt teilweise traditionelle Analysen (z. B. Meyer — Lübke 1900) und argumentiert, daß die Notwendigkeit, Mehrdeutigkeit zu vermeiden und ein Objektpronomen eindeutig zu identifizieren höchstens sekundär zu morphologischen Veränderungen beigetragen hat. Vielmehr war die Entwicklung nachgestellter Objektsklitika hauptsächlich das Ergebnis einer Ausweitung des Gebrauchs von Subjektsklitika und einer darauffolgenden Reanalyse des Elements l’. Dies wurde durch zwei Faktoren ermöglicht: eine begrenzte Anzahl möglicher Kontexte für l’ und eine bereits vorhandene alternative Interpretationsmöglichkeit. Der Vergleich mit benachbarten Varietäten zeigt, daß eine solche Entwicklung in denjenigen romanischen Sprachen nicht möglich war, die kein dem l’ ähnliches Element in begrenzt möglichen Kontexten nach Art des Früh-Piedmontesischen aufwiesen.

Arms races have been the subject of many and various explanations, but of few formal theories which manage to combine the virtues of plausibility and parsimony. Perhaps the best known is Richardson's, to which interesting modifications have been proposed by Smoker, Saaty and most recently Hamblin et al.2 Common to all these models is the assumption that arms races can be explained by an action-reaction process between the two nations involved.

THE germ of that which follows came into being many years ago in the days of my youth as a university instructor and assistant professor. It was generated by the then quite outspoken attitude of colleagues in the “exact sciences”; the sciences of which the subject-matter can be exactly weighed and measured and the force of its movements mathematically demonstrated. They assured us that the study of languages and literature had little or nothing scientific about it because: “It had no domain of concrete fact in which to work.” Ergo, the scientific spirit was theirs by a stroke of “efficacious grace” as it were. Ours was at best only a kind of “sufficient grace,” pleasant and even necessary to have, but which could, by no means ensure a reception among the elected.

In this paper an orbit computation program for artificial satellites is presented. This program is operational and it has already been used to compute the orbits of several satellites.After an introductory discussion on the subject of artificial satellite orbit computations, the features of this program are thoroughly explained. In order to achieve the representation of the orbital elements over short intervals of time a drag-free perturbation theory coupled with a differential correction procedure is used, while the long range behavior is obtained empirically. The empirical treatment of the non-gravitational effects upon the satellite motion seems to be very satisfactory. Numerical analysis procedures supporting this treatment and experience gained in using our program are also objects of discussion.

Rule: I'd like at this point to bring up the subject of cables and wireways around the telescope. We've touched upon this twice during previous sessions: the cable wrap up problem, the communications problem, and data multiplexing problem. I think we'll ask Bill Baustian if he will give us a brief run down on what the electrical run problems are, besides doubling the system every year.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

The growth of Ag films deposited on various substrate materials such as MoS2, mica, graphite, and MgO has been investigated extensively using the in situ electron microscopy technique. The three stages of film growth, namely, the nucleation, growth of islands followed by liquid-like coalescence have been observed in both the vacuum vapor deposited and ion beam sputtered thin films. The mechanisms of nucleation and growth of silver films formed by ion beam sputtering on the (111) plane of silicon comprise the subject of this paper. A novel mode of epitaxial growth is observed to that seen previously.The experimental arrangement for the present study is the same as previous experiments, and the preparation procedure for obtaining thin silicon substrate is presented in a separate paper.

With the advent of the space age and the need to determine the requirements for a space cabin atmosphere, oxygen effects came into increased importance, even though these effects have been the subject of continuous research for many years. In fact, Priestly initiated oxygen research when in 1775 he published his results of isolating oxygen and described the effects of breathing it on himself and two mice, the only creatures to have had the “privilege” of breathing this “pure air”.Early studies had demonstrated the central nervous system effects at pressures above one atmosphere. Light microscopy revealed extensive damage to the lungs at one atmosphere. These changes which included perivascular and peribronchial edema, focal hemorrhage, rupture of the alveolar septa, and widespread edema, resulted in death of the animal in less than one week. The severity of the symptoms differed between species and was age dependent, with young animals being more resistant.

The interaction of electron beams with a large variety of materials for information storage has been the subject of numerous proposals and studies in the recent literature. The materials range from photographic to thermoplastic and magnetic, and the interactions with the electron beam for writing and reading the information utilize the energy, or the current, or even the magnetic field associated with the electron beam.

The respective roles of the ribo somes, endoplasmic reticulum, Golgi apparatus and perhaps nucleus in the synthesis and maturation of melanosomes is still the subject of some controversy. While the early melanosomes (premelanosomes) have been frequently demonstrated to originate as Golgi vesicles, it is undeniable that these structures can be formed in cells in which Golgi system is not found. This report was prompted by the findings in an essentially amelanotic human cellular blue nevus (melanocytoma) of two distinct lines of melanocytes one of which was devoid of any trace of Golgi apparatus while the other had normal complement of this organelle.
