Undecidable wreath products and skew power series fields
Authors: Delon Françoise , Simonetta Patrick 
Published: April 2006

We prove the undecidability of a very large class of restricted and unrestricted wreath products (Theorem 1.2), and of some skew fields of power series (Section2). Both undecidabilities are obtained by interpreting some enrichments of twisted wreath products, which are themselves proved to be undecidable (Proposition 1.1).We consider division rings of power series in various languages:We show (Theorem 2.8) that every power series division ring k((B)), whose field of constants k is commutative and whose ordered group of exponents is noncommutative with a convex center, is undecidable in every extension of the language of rings where the valuation and the ordered group B are definable.For certain k and B we prove here the undecidability of the structurewhere X↾k((B))xB is the restriction of the multiplication to k((B)) Χ B,and γ is a given conjugation of k((B)). This shows that we cannot hope to improve our previous result, a sort of Ax-Kochen-Ershov principle for power series division rings, which ensures thatis decidable for every decidable solvable B.
Symmetry in Primitive Conventional Design
Authors: Brainerd George W. 
Published: April 2006

Although the conventional design appearing on aboriginal American ceramics has been used successfully as a diagnostic feature in archaeological pottery classification, there has been little analytical and comparative work done on this mass of material. Much of the design, despite the simplicity and wide distribution of its elements, is complicated and richly variable. This apparent complexity has been a stumbling clock in the way of its study.The purpose of this paper is to present a generally applicable, objective terminology for a classification of conventional design. The terminology is based on symmetry of arrangement, which we have found more useful than any other scheme in elucidating complex designs.
Reconnaissance of the Central San Joaquin Valley
Authors: Hewes Gordon W. 
Published: April 2006

A survey of the central San Joaquin Valley has demonstrated a threefold cultural sequence north of Stockton, upsetting the earlier view that central California archaeology lacked evidence of change; south of Tulare Lake are indications of similar cultural stratification. Before the survey the 160 miles between Stockton and Tulare Lake was known only from scattered specimens and occasional correspondence with local collectors.The area of the 1939 reconnaissance is bounded on the north by the southern limit of Schenck and Dawson's 1929 report, the Mount Diablo Base Line; on the south, by Gifford and Schenck's northern limit, the southern end of Tulare Lake; on the east and west, by the Valley drainage limits. This territory includes the basin of the second largest river in California, and was formerly occupied by the bulk of the Yokutsspeaking peoples, and by some of the Miwok and Mono.
The Locus of the Natchez Pelvis Find
Authors: Quimby George I. 
Published: April 2006

Some time between 1837 and 1844 Dr. Montroville Wilson Dickeson found a fossil human pelvis and bones of extinct animals in the vicinity of Natchez, Mississippi (Culen 1900: 113–5).In 1846 Dickeson reported this find to the Academy of Natural Sciences of Philadelphia, stating in substance that the human bone was found at least 2 feet below 3 associated skeletons of Megalonyx in a “plateau of blue clay … that underlies the diluvial drift of Natchez“ (Dickeson 1846: 106–7).
Mogollon Settlement Patterns in Pine Lawn Valley, New Mexico
Authors: Bluhm Elaine 
Published: April 2006

AbstractSettlement patterns are described for each phase of the sedentary agricultural occupation of the area from Pine Lawn phase (200 B.C.-A.D. 500) through Tularosa phase (A.D. 1100-1250), when the area was abandoned. Through time domestic structures changed from rounded to rectangular, from semi-subterranean to surface, and decreased in size. Earlier villages tended to be on higher, more defensible locations while later ones were lower, closer to water and arable land. Villages were generally random in plan, and great kivas, the only ceremonial structures identified in the area, appear to have served more than one village. From the settlement pattern data it is possible to construct a population curve for the area which may be partially explained in terms of botanical and climatological as well as cultural factors. Pine Lawn Valley Mogollon may have had some multi-village social organization which in later times may have united the entire valley. In this respect the Mogollon may have been intermediate between the well-integrated, segmented Anasazi communities in the plateau and the more politically structured Hohokam communities in the desert.
Attributes and the Discovery of Projectile Point Types: With Data from the Columbia-Fraser Region
Authors: Smith Marian W. 
Published: April 2006

The Classification of pottery types has apparently already reached a satisfactory degree of descriptive accuracy. Although problems remain, numerous site comparisons and important cultural connections have been based upon pottery. Classification of stone artifacts is not in so happy a state. Wheat has also recently called attention to this fact (1953, p. 196): “If cultures predominantly lithic in complexion are to be correlated satisfactorily with each other … we must pay the same attention to artifacts of stone, bone, shell, etc., that has yielded such valuable results in the study of pottery.” Considerable difficulties are inherent in the classification of stone implements but close inspection shows that these are further increased by a terminology which occasionally serves as much to confuse the picture as to clarify it.
Such phrases as “leaf-shaped” or “triangular” blades are common in archaeological literature. Yet the descriptive accuracy of these terms rests upon a meaningful and generally accepted contrast between leaf-shaped and triangular which is not substantiated by the inquiry into their use as presented below.
Excavations in Jamaica
Authors: Dewolf Marian 
Published: April 2006

The purpose of this paper is to report the results of excavations conducted in 1933, as yet unreported, and to correlate the findings with present knowledge of Jamaican and other West Indian prehistory. Descriptions of the sites and specimens may be of value to archaeologists in this area.Since 1933 great strides have been made in archaeological knowledge of the West Indies. Irving Rouse has correlated known cultures in most of the Greater Antilles and in some of the Lesser Antilles. He has established seven arbitrary time periods, I, IIa, IIb, IIIa, IIIb, IVa, and IVb, for the area (Rouse, 1939, 1941, 1948, 1951, 1952) on the basis of stratigraphy, sedation of modes, establishment of style sequences, and cross-dating of trade objects. During these periods four cultures existed. The period I culture is preceramic and is associated with the Ciboney Indians who may have come from North America. The first ceramic culture, Igneri, is associated with the Arawak Indians, who pushed north and east from the Orinoco Valley in period II. It lacks the ceremonial complex which distinguishes the two later ceramic cultures, sub-Taino and Taino, which developed in the Greater Antilles during periods III and IV, the former as a simpler variant of the latter.
The Central California Chronological Sequence Re-Examined
Authors: Belous Russell E. 
Published: April 2006

For a number of years the subject of California archaeology has undergone a great deal of discussion. A large measure of this discussion has been concerned with the problem of chronology. Heizer (1949) has postulated a classification of cultural and temporal relationships for central California. His chronology is based primarily on stratigraphic sequences together with intrasite comparisons and geological-chemical soil and bone analysis.This paper is an attempt to examine a part of his sequences using a new method for the chronological ordering of archaeological deposits (Brainerd 1951; Robinson 1951). The material to follow will be divided into three categories: 1) theory and method; 2) a discussion of the sequences resulting from the application of the method used here; and 3) the nature of the conclusions which one may safely draw in the light of 1) and 2) above.
An Early Speculation concerning the Asiatic Origin of the American Indian
Authors: Ives Ronald L. 
Published: April 2006

Speculations concerning the origin of the American Indian began almost as soon as it became known that America Septentrional was inhabited. Most current theories favor an Asiatic origin, with migration through northern Kamchatka and Alaska. This is supported by rather plentiful evidence. A few anthropologists postulate an island-hopping trans-Pacific migration at relatively low latitudes. This theory is supported by conclusive modern proof that such voyages are possible. Other proposed origins include Palestine (“The Lost Tribes of Israel”), Argentina (Ameghino's “Hombre Terciaro”), various lost continents (such as James Churchward's Mu), and other planets, some no longer extant. These latter theories are based either on misinterpreted evidence (such as the Hombre Terciaro), or overactive imagination (such as Mu), and merit no further consideration here.Although the theory of Asiatic origin of the American Indian is the most widely accepted today, its first proposal seems quite difficult to locate, particularly as Columbus and his crewmen believed that the inhabitants of the New World were Asiatics.
Comments on the Review of “The Effigy Mound Culture of Wisconsin”
Authors: McKern W. C. 
Published: April 2006

David Baerreis’ review of The Effigy Mound Culture of Wisconsin, by Chandler Rowe (American Antiquity, Vol. 23, No. 3, pp. 320–1), includes certain criticisms of methods and procedures underlying the author’s treat’ ment of his subject that raise important questions as to the general status of archaeological concept and methodology.For example, commenting on Rowe’s rejection of the early guess that effigy mound shapes represent clan symbols, Baerreis appears to argue that at some time, some tribe or tribes could possibly have possessed totemic patterns that might account for effigy mound shapes.
Ceramic Systems and Eastern Archaeology
Authors: Sears William H. 
Published: April 2006

AbstractThe system of ceramic taxonomy presented by Phillips for use in the Southeast is considered to be too formal and rigid. While it attempts to serve the same functions as the currently used concepts of type and variety, the proposed new system would be considerably more complex in its application. The ceramic type, as currently defined and used, is well adapted for establishing skeletal chronicle. Any modification would lessen its usefulness. A greater emphasis on including descriptive classes in reports is offered as more valuable than the adoption of a formal taxonomy. The content of the classes cannot be determined prior to description, whereas the formal taxonomy prescribes the content of each taxonomic unit. These classes would increase the utility of sherd collections by making available data which can be applied to problems, such as those of process, for which neither the type nor the proposed new varieties are suitable.
Sidney's Sister as Translator of Garnier
Authors: Beauchamp Virginia Walcott 
Published: April 2006

In the major study concerning the relationship between the French dramatist, Robert Garnier, and the Elizabethan drama, the author, A. M. Witherspoon, tends to see literary choice as primarily motivated by casual personal considerations. He claims, for example, that Garnier, living in a period of civil strife in France, chose Roman themes for several of his tragedies because he admired ‘the Roman genius for organization’. Likewise he explains the Countess of Pembroke's attraction to Garnier's tragedies in that they centered around strong-minded women like Portia and Cornelia.Although one cannot, of course, discount the importance of congeniality of theme in a dramatist's selection of a subject to portray or of a translator's choice of a work to render, one must not at the same time overlook certain other influences which govern these choices. And, in fact, since both Garnier and the Countess of Pembroke wrote as members of learned and circumscribed coteries, we might expect external influences to assume more than usual importance.
Ransom in ‘Samson Agonistes’
Authors: Gossman Ann 
Published: April 2006

Milton's comprehensive ability to synthesize diverse elements from different traditions according to his artistic purpose is one of the most outstanding ways in which he manifested his originality. Even Manoa's attempt to ransom his son, one of the most remarkably original episodes in Samson Agonistes, has not only profoundly Christian overtones, but also, I should like to suggest, two classical analogues.To the Christian reader the word ‘ransom’ inevitably suggests Christ's redemption of mankind, ‘Thy ransom paid, which Man from death redeems’. Just as surely as Job's declaration of faith, ‘I know that my redeemer liveth’, has been taken as an anticipation of Christ; the correspondences between Christ and Samson would have been evident to Milton's audience.
The African Standpoint
Authors: Gutmann Bruno 
Published: April 2006

Opening ParagraphThe State in its essential nature is power. Its character is determined by the force with which it asserts its distinction from neighbouring states, by its dealing with the organic bonds in which the life of the people finds expression, and by its success in absorbing into and developing within its own structure the underlying spirit of those bonds. The origin of the State's consciousness of power lies at the point in the interlacing roots of tribal organization where the tension between associations based on kinship and those based on age brings about a change of balance, and leadership begins to pass to the latter, the age-class becoming a warrior class which outgrows the clan and subjects kinship-groupings to its own leaders. Once this change in leadership has taken place, that is to say, when no longer the spirit of the clan but the spirit of the age-class becomes dominant, then, by reason of the resulting tightening-up of the forces of war and of expansion, it is only a question of time before the age-class associations pass into a system of vassalage, with leaders who emerge from the age-grade system and acquire an authority more or less political in character. With the individualization of the leadership goes the differentiation of function in the State, which is first required in the organization of the army. Henceforward the tasks in the service of the State are no longer dependent on a man's place in the tribal organization, but upon accomplishments which can be learned. To acquire these forms of skill, to become proficient in their use and to obtain the advantages secured by them becomes an absorbing task which is pursued in common and given stability by associations for the purpose. This is the birth of organization. Without such organizations the State cannot take form, for they alone ensure to it the concentration of the primitive forces of the tribe for the accomplishment of the aims of the State. Thus these organized associations become agencies to develop and foster the consciousness of statehood. The tribal community consciousness which still persists in the organic tribal relationships and in their leadership systems is gradually, under the absorptive power of the new state-consciousness, forced back into the realm of mere emotion and habit and finally deprived entirely of its spiritual leadership. So that what is in reality the starting-point of man's spiritual existence, namely, his membership of an organic and tribal order of society, comes to be regarded as something purely natural and as the sphere of the instinctive preservation of the species.
The Educational Work of Missionary Societies
Authors: Oldham J. H. 
Published: April 2006

The educational work of missionary societies is a wide subject, and I propose to limit what I say to three topics: first, the quality of missionary education; secondly, missions and native society; thirdly, missions and governments.When I was in Africa a few years ago I remarked on one occasion to a prominent official, ‘All the mistakes in native education in East Africa have been made by the missionaries.’ He looked at me in surprise at so frank an admission from a representative of missions. I added, ‘The reason is that they were the only people who could make them, since they have been the only people engaged in education.’ Throughout the greater part of Africa we are still only on the threshold of educational development. Ten years ago there were no education departments in Uganda or Nyasaland or Northern Rhodesia or the Belgian Congo or in Portuguese colonies, and those in other territories, British and non-British, were doing very little.
Privileged Obstruction of Marriage Rites among the Gusii
Authors: Mayer Philip 
Published: April 2006

Opening ParagraphA Sketch of two incidents recorded in my field notes will serve to introduce the subject of this paper.1. Nanyuki and his wife Mwango were completing their marriage by the enyangi ceremony. I was to see the second of the major sacrifices, which takes place at the husband's homestead. A day after the appointed time, Nanyuki informed me that everything was being held up. Mwango, he said, refused to go on unless he gave her a he-goat. He had tried all day in vain to get her one; none of his neighbours wanted to barter, and he could not afford money. I almost suspected a device for putting me off and preventing me from being present at the ceremony. Why should Nanyuki, who, I knew, was eager to get back to work in his swamp garden, allow his plans to be upset by Mwango's whim? However, his anxiety and exasperation seemed genuine enough; he told me that he could not think what to do, and would have to consult Kebaso, his dead father's brother.
Prediction of Equilibrium Partitioning of Nonpolar Organic Solutes in Water‐ Surfactant Systems by UNIFAC and COSMO‐RS Models
Authors: Buggert M. , Mokrushina L. , Smirnova I. , Schomäcker R. , Arlt W. 
Published: April 2006

AbstractIn the present study the potential of two thermodynamic‐based models (the group‐contribution UNIFAC model and the a priori predictive COSMO‐RS model) to predict solute partitioning in aqueous surfactant solutions is evaluated. In order to take into account the small size of micelles, the UNIFAC model was extended by the interfacial contribution based on the Gibbs‐Thompson equation. The applicability of the approach was successfully proved for the partitioning of nonpolar solutes (toluene, p‐xylene) in aqueous solutions of nonionic surfactants. The original COSMO‐RS model underestimates the concentration of the solute in the aqueous phase in the case of micellar systems since it does not account for the small size of micelles. At the same time, this model gives quantitative results for the octanol/water partition coefficients of both solutes under study leading to the conclusion that the affinity of both solutes to a certain solvent is well described. Thus, extending the COSMO‐RS by the interfacial term seems to be promising.
The contents of proteins and phospholipids in cloudy (veiled) virgin olive oils
Authors: Koidis Anastasios , Boskou Dimitrios 
Published: April 2006

AbstractExtra virgin olive oil is produced in the form of a “suspension–dispersion” which can persist for several months before full deposition of a residue. Many consumers and chefs prefer unfiltered raw olive oil because it looks thicker and richer in flavors. The nature of the material in the suspension–dispersion is poorly described. The presence of proteins has been connected with the appearance of the “veiled” oil and also with its oxidative stability, although there are discrepancies in the literature with regard to their levels. The level of phosphorus, a measure of phospholipids, is also poorly studied. This work aims at quantifying proteins and phospholipids in cloudy olive oil. For the analysis of proteins, a practical method is used that can be applied for routine analysis. The proteins are precipitated with acetone and determined colorimetrically using the Bradford method suitably modified to measure protein dye‐binding at low concentrations. Twenty three virgin and one refined olive oil samples from different places in Greece were all found to have protein levels below 2.5 mg/kg. In most of the samples, values were lower after filtration of the cloudy oils. In the refined oil samples, protein was hardly determined (value ≤0.1 mg/kg). Phosphorus levels ranged from 0.8 to 4.8 mg/kg. These correspond to approximately 21–124 mg/kg of phospholipids. The results are discussed in relation to the oxidative and physicochemical stability of the veiled oils.
Generalized lattice‐BGK concept for thermal and chemically reacting flows at low Mach numbers
Authors: Hänel D. , Lantermann U. , Kaiser R. , Wlokas I. 
Published: April 2006

AbstractThe lattice‐BGK method has been extended by introducing additional, free parameters in the original formulation of the lattice‐BGK methods. The relationship between these parameters and the macroscopic moment equations is analysed by Taylor series and Chapman–Enskog expansion. The parameters are determined from the macroscopic moment equations by comparisons with the governing equations to be modelled. Extensions are presented for the Navier–Stokes equations at low Mach numbers in Cartesian or axisymmetric coordinates with constant or variable density, for scalar convection–diffusion equations and for equations of Poisson type. The generalized lattice‐BGK concept is demonstrated by two applications of chemical engineering. These are the computation of chemically reacting flow through an axisymmetric reactor and of the transport and deposition of particles to filters under the action of different forces.

Smoothed binary regression quantiles
Authors: Kordas Gregory 
Published: April 2006

AbstractThis paper extends results regarding smoothed median binary regression to general smoothed binary quantile regression, discusses the interpretation of the resulting estimators under alternative assumptions, and shows how they may be used to obtain semiparametric estimates of counterfactual probabilities. The estimators are applied to a model of labour force participation of married women in the USA. We find that the elasticity with respect to non‐labour income is significantly negative only for women that belong to the middle of the conditional willingness‐to‐participate (WTP) distribution. In comparing the quantile models with parametric logit and semiparametric single‐index specifications, we find that the models agree closely for women around the centre of the WTP distribution, but there are considerable disagreements as we move towards the tails of the distribution.

Published: April 2006

Abstract[11‐(Acetylthio)‐1‐oxoundecyl]‐ferrocene and 1,1″‐Dithiobis‐ferrocene are inserted into alkanethiolate self‐assembled monolayers from solution. Upon annealing, the inserted molecules form separated domains, which protrude as islands from the surrounding monolayer. The resulting thin‐films are studied by UHV‐STM. For both compounds the density of the molecules in close packed SAMs is determined. Furthermore for ferroceneundecanethiols the molecular structure and orientation of the endgroups is resolved.
