AbstractConventional direct methods, which work so well for small structures, are less successful for macromolecules. Where it has been demonstrated that a solution might be found using direct methods it is then found that the usual figures of merit are unable to distinguish the few good sets of phases from the large number of sets generated. The reasons for the difficulties with very large structures are considered from a first-principles approach taking into account both the factors of having a large number of atoms and low resolution data. A proposal is made for trying to recognize good phase sets by taking a large structure as a sum of a number of smaller structures for each of which a conventional figure of merit can be applied.

Theory Competition

To overcome the crisis in the sphere of argumentation studies, the project proposes a logical-cognitive concept of argumentation which is a compound formalized theory that includes formalisms for modeling argumentation of different types, a relevant conceptual framework and a methodology for the use of scientific research in the practice. Three types of argumentation are defined: theoretical (two types) and practical. Theoretical argumentation is a critical discussion of the agents’ knowledge and opinions about facts aimed to substantiate a certain view or to change it – i.e. persuasion. Practical argumentation is a critical discussion of opinions about actions which includes, in addition to the statements about knowledge and opinions, statements of a non-descriptive nature about the agents’ values and intentions to adhere to a certain line of behavior. The study of argumentation needs to focus on the large structures that reflect specifics of the criticism and defense of the positions of the parties. An atom unit of such study is the argument as a statement of reason, while its molecular elements are the argumentative structure of a dispute (frame), a multitude of arguments that express the parties’ positions, a multitude of the agents’ knowledge and opinions that act as the bases for the formation of positions, lines of behavior, etc. Within the framework of this trend, both indefeasible (deductive) and defeasible argumentations can be studied. The argumentation effectiveness can be assessed based on the procedural semantics and using analogues of such logical notions as consistency and completeness. Modern approaches to the argumentation, including those claiming the compound status, can be classified using two methods: based on the substantive and practical criteria. Importance of the research outcomes amounts to the theoretical and methodological role of the new conception of argumentation and the general “umbrella” term argumentation that allows systematizing the manifold research and educational approaches and concepts in this field and is associated with communicative nature of modern social life where efficiency and social success rely on argumentative and narrative competences.

This article offers insights into the organization of Scioto Hopewell craft production and examines the implications of this organization through the lens of ritual economy. We present a novel analysis of investigations at the North 40 site, concluding that it is a craft production site located on the outskirts of the renowned Mound City Group. High-resolution landscape-scale magnetic survey revealed a cluster of three large structures and two rows of associated pits; one of the buildings and three of the pits were sampled in excavations. Evidence from the North 40 site marks this as the best-documented Scioto Hopewell craft production site. Mica, chert, and copper were crafted here in contexts organized outside the realm of domestic household production and consumption. Other material remains from the site suggest that crafting was specialized and embedded in ceremonial contexts. This analysis of the complex organization of Scioto Hopewell craft production provides grounds for further understanding the elaborate ceremonialism practiced by Middle Woodland (AD 1–400) societies and adds to the known complexity of craft production in small-scale societies. Furthermore, this article contributes to a growing body of literature demonstrating the utility of ritual economy as a framework for approaching the sociality of small-scale societies.

Distributed Measurement

ABSTRACTStructurally integrated optical fiber sensors form the basis for smart structure technology. Over the past decade a variety of sensor configurations have been developed for measurement of strains and deformations in structures. Strains and deformations alter the refractive index and the geometry of the optical fiber material. These changes perturb the intensity, phase, and polarization of the light-wave propagating along the probing fiber. The optical perturbations are detected for the determination of strain. The research presented here describes the development of a new optical fiber sensor system for measurement of structural strains based on white light interferometry. An optical switch provides for multiplexing of strain signals from various locations in the structure. Redundant Bragg grating type fiber optic sensors as well as strain gauges were employed for comparison and verification of strain signals as measured by the new system. The system provides capability for distributed sensing of strains in large structures.
