theorizing non-linear communities: on social deviance and housing the homeless

Theories of deviance abound; however, little attention has been given to the construction and meaning of deviance in postmodern society. According to some theorists, one conceptual variant of postmodernism is chaology or non-linear dynamical systems theory. In this article, the relevance of chaos theory for advancing our understanding of social deviance is examined. In particular, such notions as non-linearity, fractal space, attractors, self-similarity, bifurcations, and dissipative structures are described as constitutive of the postmodern agenda. These insights are then applied to the difficult and complex issue of housing the homeless, especially shelter strategies designed to create personhood and place for the poor and disenfranchised.     

Vitality rediscovered: theorizing post-Soviet ethnicity in Russian social sciences

Based on materials collected during a fieldwork in Barnaul (Siberia, Russia) in 2001–2004, the article explores two provincial academic discourses that are focused on issues of Russian national identity. Ethnohistories of trauma address Russia’s current problems through the constant re-writing of the country’s past in order to demonstrate the non-Russian character of its national and state institutions. In the second discourse, ethno-vitalism, the struggle over constructing and interpreting the nation’s memory of the past is replaced with a similar struggle over constructing and interpreting perceptions of the nation’s current experience. Produced by professional intelligentsia, these frameworks and discourses provide a useful link to understanding imaginary constructions of the national belonging in a situation where more positive ways of inventing traditions and imagining communities are unavailable or discredited.

Substantive theorizing

This paper outlines, for purposes of discussion and debate, an ecologically oriented approach to theory and research in psychology and related social sciences. This approach, labeled "substantive theorizing", is intended as a constructive response to recent critiqies of the logical positivism paradigm. Substantive theorizing is presented as the intersection of a series of choices by researchers, including decisions to focus on limited but socially important domains; to use multiple methods; to develop intimate familiarity with chosen domains; and to examine processes in their natural social and temporal contexts. The approach emphasizes the process, rather than the product, of conceptual framing and development. Among the projected benefits of substantive theorizing are development of new concepts and procedures, blurring of disciplinary boundaries, greater understanding of socially important domains, and increased utility of research for policy and practice. Projected costs include long-term research commitments and lack of support from academic departments and research funding agencies.     

Language structure: psychological and social constraints

In this article we discuss the notion of a linguistic universal, and possible sources of such invariant properties of natural languages. In the first part, we explore the conceptual issues that arise. In the second part of the paper, we focus on the explanatory potential of horizontal evolution. We particularly focus on two case studies, concerning Zipf’s Law and universal properties of color terms, respectively. We show how computer simulations can be employed to study the large scale, emergent, consequences of psychologically and psychologically motivated assumptions about the working of horizontal language transmission.     

A multi-objective mathematical programming problem with fuzzy relation constraints

In this study we discuss the problem of multi-objective mathematical programming with constraints defined by ‘max-min’ composite fuzzy relation equations. Since the feasible region is normally non-convex, the properties of the efficient points of a non-convex feasible region under multi-objectives are investigated and illustrated by examples. The necessary and sufficient conditions are proposed and proved. To facilitate decisions, a procedure that transforms these efficient points of an interval-valued decision space into a constant-valued decision space is proposed when the level of confidence is given by a decision maker. Then the transformed problem becomes a multi-attribute decision problem that can be evaluated by Yager's method to find the optimal alternative.     

Hume on the social construction of mathematical knowledge

Mathematics for Hume is the exemplary field of demonstrative knowledge. Ideally, this knowledge is a priori as it arises only from the comparison of ideas without any further empirical input; it is certain because demonstration consist of steps that are intuitively evident and infallible; and it is also necessary because the possibility of its falsity is inconceivable as it would imply a contradiction. But this is only the ideal, because demonstrative sciences are human enterprises and as such they are just as fallible as their human practitioners. According to the reading suggested here, Hume develops a radical sceptical challenge for mathematics, and thereby he undermines the knowledge claims associated with demonstrative reasoning. But Hume does not stop there: he also offers resources for a sceptical solution to this challenge, one that appeals crucially to social practices, and sketches the social genealogy of a community-wide mathematical certainty. While explaining this process, he relies on the conceptual resources of his faculty psychology that helps him to distinguish between the metaphysics and practices of mathematical knowledge. His account explains why we have reasons to be dubious about our reasoning capacities, and also how human nature and sociability offers some remedy from these epistemic adversities.

     

Perspective-taking in dialogue as self-organization under social constraints

We present a dynamical systems account of how simple social information influences perspective-taking. Our account is motivated by the notion that perspective-taking may obey common dynamic principles with perceptuomotor coupling. We turn to the prominent HKB dynamical model of motor coordination, drawing from basic principles of self-organization to describe how conversational perspective-taking unfolds in a low-dimensional attractor landscape. We begin by simulating experimental data taken from a simple instruction-following task, in which participants have different expectations about their interaction partner. By treating belief states as different values of a control parameter, we show that data generated by a basic dynamical process fits overall egocentric and other-centric response distributions, the time required for participants to enact a response on a trial-by-trial basis, and the action dynamics exhibited in individual trials. We end by discussing the theoretical significance of dynamics in dialog, arguing that high-level coordination such as perspective-taking may obey similar dynamics as perceptuomotor coordination, pointing to common principles of adaptivity and flexibility during dialog.     

Structuralist reduction concepts as structure-preserving maps

The aim of this paper is to characterize the various structuralist reduction concepts as structure-preserving maps in a succinct and unifying way. To begin with, some important intuitive adequacy conditions are discussed that a good (structuralist) reduction concept should satisfy. Having reconstructed these intuitive conditions in the structuralist framework, it turns out that they divide into two mutually incompatible sets of requirements. Accordingly there exist (at least) two essentially different types of structuralist reduction concepts: the first type stresses the existence of a deductive or inferential link between the reducing and the reduced theory; the second type emphasizes the greater explanatory power the reducing theory should have in comparison with the reduced theory. The problem of the incompatibility of equally plausible reduction concepts is treated in the last section and a proposal is made for its solution consisting in the definition of a multiple synthetizing reduction relation.     

Deductive Reasoning in the Structuralist Approach

The distinction between the syntactic and the semantic approach to scientific theories emerged in formal philosophy of science. The semantic approach is commonly considered more advanced and more successful than the syntactic one, but the transition from the one approach to the other was not brought about without any loss. In essence, it is the formal analysis of atomic propositions and the analysis of deductive reasoning that dropped out of consideration in at least some of the elaborated versions of the semantic approach. In structuralist theory of science, as founded by Sneed and Stegmüller, the focus is on global propositions concerning the question of whether or not certain empirical systems satisfy a set-theoretic predicate that encodes the axioms of a scientific theory. Hence, an analysis of deductive reasoning from atomic premisses with the help of a given theory is missing. The objective of the present paper is to develop a deductive system on the basis of the structuralist framework. This system comes with a novel formulation of empirical propositions in structuralism.     

Methodological Patterns In A Structuralist Setting

A new approach to analyze scientific methods as patternsof state transitions is proposed and exemplified by the two mostimportant, general methods: induction and deduction. Though only`local' states of science are considered in this paper, includinghypotheses, data, approximation and degree of fit, the approach caneasily be extended to more comprehensive kinds of states. Two `pure'forms of induction are distinguished, enumerative and hypothesisconstruction induction. A combination of these two forms is proposedto yield a more adequate picture of induction. While the pure forms ofinduction are clearly distinct from the deductive pattern, the patternof the combined form of induction is very similar to the latter. Thepresent account of scientific methods not only points out thedifferences between different methods but – in contrast to usualdiscussions of methodology – also clarifies what they have in common.     

A mathematical model for social influences on perceptual judgments

A mathematical model based upon signal detection theory is developed that characterizes social influences upon judgments of a stimulus. A social influence cue and the physical aspects of the stimulus were assumed to have independent effects upon performance. A visual movement discrimination task was employed in which subjects could make their judgment either before or after a cue that they had been led to believe was the response of another subject. The accuracy of this “response” was varied. The model provided a good account of the data. A model-based estimate of the magnitude of the influence effect indicated that this effect was greater when the “other” was highly accurate. The model provided an interpretation of social influences on perceptual judgments in which influence pressures have their effects only when subjects' sensory impressions are ambiguous.
