proper opportunity of the city of genoa, its cooperation during the crusades, and the evolution in the terms of trade organization and practices at the same time that mongol empire was establishing, formed a new round of intercontinental trade . the importance of commerce for the mongol continued as a tradition in ilkhanids. genoese commercial presence in eastern ports and the black sea and als...

This paper describes work carried out on a model for the evolution of graph classes in complex objects. By defining evolution rules and propagation strategies on graph classes, we aim to define a user-definable means to manage data evolution model which tackles the complex nature of the classes managed, using the concepts defined in object systems. So, depending on their needs and on those of t...

We review the relationship between polygyny and HIV and identify a positive individual-level correlation, and a negative ecological correlation. We subsequently examine two mechanisms that contribute to the individual-level correlation. First, we find that men in polygynous marriages have more extramarital sex than men in monogamous unions (both in terms of self reports and in terms of spousal ...

where the variables α and β range over entities of some sort, and where ∼ is an equivalence relation on this sort of entity. Frege’s inconsistent Basic Law V shows that not every such principle is acceptable. A variety of criteria for acceptable abstraction have been proposed.1 In this note I analyze the logical relations between some of the proposed criteria, in particular conservativeness, ir...

The importance of a person's spirit and eternal destiny are eclipsed in American medi- cine. The most alarming effect of this eclipse is that the prevalence of burnout among physicians is high (about 46 percent) and growing.' It is alarming because trends that deplete the physician's spirit tragically impair the physician's capacity as a healer and as one who renews the spirit.

Sunni Islam has no supreme legal authority and disagreement by doctors of Islamic law over all issues not clarified by Islamic law is physiological. This is the case with Medically Assisted Reproduction: after an initially critical attitude, tolerance, limited exclusively to homologous practices, is spreading, whilst recourse to heterologous practices is considered on a par with adultery or for...

Premarital precursors of infidelity were evaluated in a sample of 72 couples (N = 144) who were taking part in a longitudinal study of marriage. Premarital self-report and observational data were compared for couples who experienced infidelity and those who did not experience infidelity in the first years of marriage. Couples in which the male engaged in marital infidelity were characterized, p...

This paper proposes a novel surrogate-model-based multiobjective evolutionary algorithm called Differential Evolution for Multiobjective Optimization Based on Gaussian Process Models (GP-DEMO). The algorithm is based on the newly defined relations for comparing solutions under uncertainty. These relations minimize the possibility of wrongly performed comparisons of solutions due to inaccurate s...

A systematic derivation is presented of the twist–2 anomalous dimensions of the general quark and gluon light–ray operators in the generalized Bjorken region in leading order both for unpolarized and polarized scattering. Various representations of the anomalous dimensions are derived in the non–local and local light cone expansion and their properties are discussed in detail. Evolution equatio...

Cretaceous mafic dykes in the Moyar Shear Zone (MSZ) area, north Kerala, India, provide signatures to probe into the nature of their source and thereby the evolution of the Mesozoic lithospheric mantle beneath the South Indian Granulite Terrain (SIGT). Bulk of the dykes in northern parts of Kerala is broadly in spatial association with the shear system. Mafic dykes striking NE-SW, NWSE, NNW-SSE...
