This paper takes a critical look at theory-free, statistical methodologies for processing and interpreting data taken from respondents answering a set of dichotomous (yes-no) questions. The basic issue concerns to what extent theoretical conclusions based on such analyses are invariant under a class of "informationally equivalent" question transformations. First the notion of Boolean equivalence of two question sets is discussed. Then Lazarsfeld's latent structure analysis is considered in detail. It is discovered that the best fitting latent model depends on which (...) one of the many informationally equivalent question sets is used. This fact raises a number of methodological problems and pitfalls with latent structure analysis. Related problems with other methodologies are briefly discussed. (shrink)

The increasing application of network models to interpret biological systems raises a number of important methodological and epistemological questions. What novel insights can network analysis provide in biology? Are network approaches an extension of or in conflict with mechanistic research strategies? When and how can network and mechanistic approaches interact in productive ways? In this paper we address these questions by focusing on how biological networks are represented and analyzed in a diverse class of case studies. Our examples span from (...) the investigation of organizational properties of biological networks using tools from graph theory to the application of dynamical systems theory to understand the behavior of complex biological systems. We show how network approaches support and extend traditional mechanistic strategies but also offer novel strategies for dealing with biological complexity. (shrink)

Design thinking in general, and optimality modeling in particular, have traditionally been associated with adaptationism—a research agenda that gives pride of place to natural selection in shaping biological characters. Our goal is to evaluate the role of design thinking in non-evolutionary analyses. Specifically, we focus on research into abstract design principles that underpin the functional organization of extant organisms. Drawing on case studies from engineering-inspired approaches in biology we show how optimality analysis, and other design-related methods, play a specific methodological (...) role that is tangential to the study of adaptation. To account for the role of these reasoning strategies in contemporary biology, we therefore suggest a reevaluation of the connection between design thinking and adaptationism. (shrink)

G. E. Moore observed that to assert, 'I went to the pictures last Tuesday but I don't believe that I did' would be 'absurd'. Over half a century later, such sayings continue to perplex philosophers. In the definitive treatment of the famous paradox, Green and Williams explain its history and relevance and present new essays by leading thinkers in the area.

G. E. Moore famously observed that to assert ‘I went to the pictures last Tuesday but I do not believe that I did’ would be ‘absurd’. Moore calls it a ‘paradox’ that this absurdity persists despite the fact that what I say about myself might be true. Krista Lawlor and John Perry have proposed an explanation of the absurdity that confines itself to semantic notions while eschewing pragmatic ones. We argue that this explanation faces four objections. We give a better (...) explanation of the absurdity both in assertion and in belief that avoids our four objections. (shrink)

The rural health context in the United States presents unique ethical challenges to its approximately 60 million residents, who represent about one quarter of the overall population and are distributed over three-quarters of the country’s land mass. The rural context is not only identified by the small population density and distance to an urban setting but also by a combination of social, religious, geographical, and cultural factors. Living in a rural setting fosters a sense of shared values and beliefs, a (...) strong work ethic, self-reliance, and a tendency for close-knit extended social structures where overlapping relationships are commonplace.

The comprehension of anaphoric relations may be guided not only by discourse, but also syntactic information. In the literature on online processing, however, the focus has been on audible pronouns and descriptions whose reference is resolved mainly on the former. This paper examines one relation that both lacks overt exponence, and relies almost exclusively on syntax for its resolution: adjunct control, or the dependency between the null subject of a non-finite adjunct and its antecedent in sentences such as Mickey talked (...) to Minnie before ___ eating. Using visual world eyetracking, we compare the time course of interpreting this null subject and overt pronouns (Mickey talked to Minnie before he ate). We show that when control structures are highly frequent, listeners are just as quick to resolve reference in either case. When control structures are less frequent, reference resolution based on structural information still occurs upon hearing the non-finite verb, but more slowly, especially when unaided by structural and referential predictions. This may be due to increased difficulty in recognizing that a referential dependency is necessary. These results indicate that in at least some contexts, referential expressions whose resolution depends on very different sources of information can be resolved approximately equally rapidly, and that the speed of interpretation is largely independent of whether or not the dependency is cued by an overt referring expression.

This essay hypothesizes that the Universe contains a self-reproducing neural network of Black Holes with computational abilities—i.e., the Universe can “think”! It then rephrases the Final Anthropic Principle to state: “Intelligent information-processing must come into existence in each new Universe to assure the birth of intelligent successor universes”. Continued research into the theory of Early Universe and Black Hole information storage, processing and retrieval is recommended, as are observational searches for time-correlated electromagnetic and gravitational wave emission patterns from widely separated (...) Black Hole transient events indicative of the existence of a universal inter-Black Hole faster-than-light communications network. (shrink)

The proposals gathered under the rubric of “Hilbert Problems” (HPs) demonstrate the progress, the disciplinary maturity, and the distinctive analytical potential of bio-cultural approaches to the study of religion. The HPs identify and investigate the ubiquitous evolutionary, cognitive, and neural processes that undergird the disparate array of religious phenomena. Many of the proposals offer fresh perspectives on conventional components of religion by connecting the study of religion to disciplines as diverse as psychiatry, semiotics, and statistics. In these ways, the HPs (...) demonstrate the naturalness of religion in the evolution of the human species. This short commentary briefly explores the issues of the definition of religion, religion and morality, the naturalistic basis for religious hermeneutics, and tradition-centered research and suggests ways in which the humanities can inform and enrich bio-cultural approaches. It proposes that collaboration between science and the humanities can advance research and help illuminate religion’s relevance to humanity’s lived experience. (shrink)

Periodization is rooted in historical theory. It reflects our priorities, our values, and our understanding of the forces of continuity and change. Yet periodization is also subject to practical constraints. For pedagogical reasons, world historians must seek reasonable symmetry between major historical eras despite huge discrepancies in the availability of historical data for separate time periods and for different areas of the world.Political issues arise in periodization. Should world history provide integrated treatment of the evolution of civilization, focusing upon the (...) most developed societies ? Or should it provide equal time to cultures outside the evolutionary mainstream ? If integration is to be preferred--as this article advocates--it is incumbent upon integrationists to provide some overarching theory of change to demonstrate how the destinies of the world's peoples have been linked through the millennia.Although the article attempts to demonstrate how comprehensive theories of change can facilitate the formulation of world history periodization, it does not minimize the difficulty of developing a universally operative organic theory of change. It examines several theoretical orientations, but principal attention is given to world-systems analysis, the most fully refined and well articulated body of theory currently commended as a vehicle for structuring world history.Acknowledging that no body of theory currently achieves a satisfactory universal integration of world history and that this situation may prevail in the future, the author recommends, for the present, an eclectic periodization of four epochs divided at roughly 1000 B.C.E., 400-600 C.E., and circa. 1492.

Stanovich & West (S&W) appear to overlook the adaptivity of variation. Behavioral variability, both between and within individuals, is an absolute necessity for phylogenetic and ontological adaptation. As with all heritable characteristics, inter-individual behavioral variation is the foundation for natural selection. Similarly, intra-individual variation allows a broad exploration of potential solutions. Variation increases the likelihood that more optimal behaviors are available for selection. Four examples of the adaptivity of variation are discussed: (a) Genetic variation as it pertains to behavior and (...) natural selection; (b) behavioral and cognitive aspects of mate selection which may facilitate genetic diversity; (c) variation as a strategy for optimizing learning through greater exploration; and (d) behavioral variation coupled with communication as a means to propagate individually discovered behavioral success.
