Structural equivalence: Meaning and definition,computation and application

This paper presents a generalization of the concept of “structural equivalence”, the key concept in algebraic approaches to the study of social networks. Two points in a graph or set of relations will be called “structurally related” if they are connected in the same ways to structurally related points.It is suggested that this new definition suitably weakens Lorrain and White's categorical approach, and is more appropriate than CONCOR. Structural relatedness is compared to these approaches via several simple examples.     

Identifying regular blocks in valued networks: A heuristic applied to the St. Marks carbon flow data,and international trade in cereal products

While the concept of regular equivalence is equally applicable to dichotomous as well as valued networks, the identification of regular blocks in regular blockmodels is somewhat problematic when dealing with valued networks. Applying the standard procedure for identifying ties in such blockmodels, a procedure perhaps most suited for dichotomous networks, does tend to generate block images and reduced graphs that differ from intuitive notions of such structures.     

Relations,residuals, regular interiors,and relative regular equivalence

Given a relation α (a binary sociogram) and an a priori equivalence relation π, both on the same set of individuals, it is interesting to look for the largest equivalence π^o that is contained in and is regular with respect to α. The equivalence relation π^o is called the regular interior of π with respect to α. The computation of π^o involves the left and right residuals, a concept that generalized group inverses to the algebra of relations. A polynomial-time procedure is presented (Theorem 11) and illustrated with examples. In particular, the regular interior gives meet in the lattice of regular equivalences: the regular meet of regular equivalences is the regular interior of their intersection. Finally, the concept of relative regular equivalence is defined and compared with regular equivalence.     

The Construction of Historical Equivalence: Weighing the Red and Brown Scares

Whether two events “belong together,” cognitively and in terms of collective memory, requires that we develop classification strategies. Historical equivalence refers to the perception that two events, separate in space and time, belong to the same cognitive category, or speak to the same issues. They are “good to think together.” Rejecting a radical constructionism that suggests that everything is a matter of ontological preference, I argue, following Gubrium (1993) , that interactionists should prefer a cautious naturalism. While interests and resources affect the presentation of historical claims, an obdurate reality permits the evaluation of empirical claims of comparability. To determine historical equivalence, we need to examine events in light of their magnitude, metaphorical continuity, analogous causation, and comparative effects. To examine the construction of historical equivalence, I discuss the similarities and differences between the Red Scares of 1919 and the late 1940s and the Brown Scare of the early 1940s. What you choose as an historical analogy begins and ends the conversation. —Elazar Barkan, “On Accepting Historical Responsibility: Refugees and the Right of Return” (2004)     

Transaction fee economics in the Ethereum blockchain

We study the economic determinants of transaction fees in the Ethereum blockchain. We estimate an empirical model based on queueing theory and analyze the factors determining the “gas price” (transaction cost per unit of service, “gas”). Using block- and transaction-level data from the Ethereum blockchain, we show that changes in service demand significantly affect the gas price—when there is high block utilization, per-unit fees increase on average, with strong nonlinear effect above 90% utilization. The transaction type is another important factor—larger fraction of regular transactions (direct transfers between users) is associated with higher gas price.     

The Importance of Sex in the Lives of Women Living with HIV: A Critical Quantitative Analysis

The authors explored the importance of sex for 1,289 women living with HIV in Canada. Approximately half of women viewed sex as “very” (19.6%) or “somewhat” important (32.3%) and the remaining reported “neither important or unimportant” (22.0%), “somewhat unimportant” (5.4%), or “not at all important” (20.1%). Women who had a regular sex partner, identified as African, Caribbean, or Black, were more educated, believed HIV treatment prevents transmission, or had better physical health-related quality-of-life reported greater importance of sex, whereas those who were older, used illicit drugs, or experienced violence in adulthood reported lesser importance. Findings underscore the diversity of women's perspectives within the context of their lives.     

Making sources of energy: the case of coal (1900–1936)

Recent contributions to a sociological analysis of energy and society focus mostly on its political, economic and technological organization. Yet contrary to other parts of nature, little social scientific attention has been paid to how politics, economics and technology have come to produce and stabilize the concept of energy in the first place and how different natural materials were transformed into “sources of energy.” Drawing from insights of the sociology of comparison, quantification and commensuration, “energy” in this paper is conceived as a “statistical object,” around which a public discourse develops in which comparisons between resources are drawn. Since the beginning of the twentieth century, this discourse has been more and more stabilized by the regular, public production and ever tighter net of elements of comparison, the creation of a highly abstract, potentially quantified point of comparison, and the definition of various criteria tying the compared entities together with more general models and narratives. This theoretical framework is put into practice by an explorative analysis of coal classification in the first quarter of the twentieth century. In this empirical analysis, three fields are identified where coals were “made the same”: engineering, economics and resource statistics. It is shown that the “calorific value” plays an important role for classification in all three fields and, furthermore, constitutes a measure that links coal to other fuels.     

Circulation,Internationalization, Globalization of the Question of Memory

The connotations linked to the notion of memory – when it is defined as collective or social– have only recently emerged. “Memory” is a mostly polysemic concept in social sciences. It also represents a social phenomenon. If the discourse surrounding memory seems to be largely internationalised, it has come at the cost of discrepancies in temporalities, theoretical traditions and objects of history. A general synthesis would be improbable. Today it appears that three big problematical concepts co-exist, from French literature but largely exported: the “realms of memory” (Pierre Nora), the “work of recollection” (Paul Ricoeur), the “frameworks of memory” (Maurice Halbwachs).     

Authority and the pursuit of order in organizational performance

The paper seeks to examine the site of performance, the spatial context of the dramatic act, and to consider the various ways in which performance is regulated, ordered and sustained. In particular, the paper is concerned with the relationship between authority and propriety in the regulation of the performance site and with the transformational metaphors which sustain the trajectory of the performance. The basic premise on which the argument rests is that there is a equivalence of sign-imagery as appropriate to liturgical performance which is the basis of some forms of organisational behaviour and that this equivalence permits more than the mere playing out of ritualistic behaviour: it appropriates the image in the reproduction and re-presentation of its forms. Consequently, the significance of the elevation, for instance, of The Cross or the consecrated Host, the notion of ritualistic cleansing, of humiliation, of redemptive acts, of public confession, become emblematic means of achieving organisational incorporations and of achieving movement from the isolated “I” to the collective “We”.     

The Most Cherished Myth: Puritanism and Liberty Reconsidered and Revised

This paper revisits and reconsiders the prevailing assumption or conventional wisdom about the association or affinity between Puritanism and liberty in historically Puritan societies, especially America and to a lesser extent Great Britain. It argues and elaborates on that the “Puritanism and liberty” equation or link is a naïve assumption, speculative explanation or cherished liberal-democratic mythology analogous and related to, as well as even more enduring and prevalent than, what contemporary sociologists call the “beloved myth” of an elective affinity or connection between Calvinism and modern capitalism. The paper aims to fill in a void in the current sociological literature in which attempts to question and reveal the Puritanism and liberty equivalence as a myth are relatively infrequent. Overall, the paper aims to contribute to the existing literature on the relationships between Puritanism, Calvinism and other ascetic Protestantism on the one hand and modern democratic society on the other.     

Verfolgungsnetzwerke

In the literature, the power structures during the rule of National Socialism are characterized as a more or less uncoordinated mix of administrative bodies, which often worked parallel to or even against each other. This structure has been widely labeled as “Polycracy” or even as “Organized Chaos”. It is yet unknown, however, whether these characteristics intensified or mitigated the persecution of the Jewish population in Europe under Nazi rule. Also, an operationalization of the “Polycracy” concept and a subsequent measurement of these specific features of Nazi rule has yet to be done. In the article, the structure of the Nazi government and persecution apparatus is operationalized through division of labor and differentiation of power applying the network concept. These structural characteristics are then measured using quantitative network analysis. This is demonstrated by presenting the case of the persecution of “converted Jews” in the Netherlands from summer 1942 to spring 1943. In the conclusion, the potential of network analysis for holocaust research and the implications of the findings for the overarching questions in this research area are discussed.     

A DEFINITION OF GENERALIZED CORRELATION AND ITS APPLICATION FOR PORTFOLIO ANALYSIS

This paper presents a partial solution to the problem: what is a “useful” concept of correlation within the context of the general expected utility model? We develop a concept of generalized correlation and show that it is “useful,” by establishing some new “diversification theorems” for the expected utility portfolio-choice model. Our main results are for a two asset model, but we are able to establish some n-asset results which are of some practical interest. Some “non-diversification theorems” are also derived.     

Ritual Power in Interaction*

Research (by a self-styled participant observer) into two fashions of persons—nurses and punks—lends unexpected significance to the ritual “frame” as this appears in Erving Goffman's thought. A new concept that was only implicit in Goffman's ritual frame is demanded by the research experiences. This is “ritual power.” Ritual power, especially when it is strong, is like “presence” or “possession”, and it may well exert a major claim on interactants' consciousnesses (whether the interactants are displaying it or appreciating it). Of course, it must follow that verbal forms which try to define ritual power will do so the more powerfully the more they arrest the reader's attention. So it may not be a good idea to use sociological rhetoric of any sort to suggest that punks and nurses are exemplary referents of “ritual power”, but this last possibility is only latent in what follows.     

Inventing the axial age: the origins and uses of a historical concept

The concept of the axial age, initially proposed by the philosopher Karl Jaspers to refer to a period in the first millennium BCE that saw the rise of major religious and philosophical figures and ideas throughout Eurasia, has gained an established position in a number of fields, including historical sociology, cultural sociology, and the sociology of religion. We explore whether the notion of an “axial age” has historical and intellectual cogency, or whether the authors who use the label of a more free-floating “axiality” to connote varied “breakthroughs” in human experience may have a more compelling case. Throughout, we draw attention to ways in which uses of the axial age concept in contemporary social science vary in these and other respects. In the conclusion, we reflect on the value of the concept and its current uses and their utility in making sense of human experience.     

Seeing the wood for the trees: Social Science 3.0 and the role of visual thinking

Social Science is increasingly called on to address “grand challenges”, “wicked problems”, “societal dilemmas” and similar problematiques. Examples include climate change, the war on drugs and urban poverty. It is now widely agreed that the disciplinary structure of academic science, with its journals, curricula, peer communities, etc., is not well suited to such trans-disciplinary, ill-bounded, controversial issues, but the ways forward are not yet clear or accepted by the mainstream. The concept of a next generation paradigm of “Science 3.0” has emerged through work on sustainability systems analysis, and for this multiple channels for learning, thinking and communications are essential. Visual thinking in its many forms (from technical representation or mapping, to photography or video, to design or illustration, to fine art) can bring to the table tacit and “felt” knowledge, creative experience and links from analysis with synthesis. This paper first sketches the contours of a Social Science 3.0, and then demonstrates with examples how visual thinking can combine with rational argument, or extend beyond it to other forms of experience.     

A Theory of Access*

Abstract The term “access” is frequently used by property and natural resource analysts without adequate definition. In this paper we develop a concept of access and examine a broad set of factors that differentiate access from property. We define access as “the ability to derive benefits from things,” broadening from property's classical definition as “the right to benefit from things.” Access, following this definition, is more akin to “a bundle of powers” than to property's notion of a “bundle of rights.” This formulation includes a wider range of social relationships that constrain or enable benefits from resource use than property relations alone. Using this framing, we suggest a method of access analysis for identifying the constellations of means, relations, and processes that enable various actors to derive benefits from resources. Our intent is to enable scholars, planners, and policy makers to empirically “map” dynamic processes and relationships of access.     

In search of experiential knowledge

In recent years, the concept of “experiential knowledge” has increasingly been used to characterize the distinctive contribution patients make to decision-making in the health field. Even though it seems well-nigh impossible to characterize it precisely, there is no doubting its significance for decision-making contexts ranging from the individual to the political. Since individual experiences of any condition or treatment differ widely, whose experiences come to constitute “knowledge”? In this paper, I argue that, rhetoric notwithstanding, numerous constraints “filter” the experiences which come to function as “experiential knowledge”. Looking to the future of health care, likely to be marked by growing inequalities, I suggest that a reflection on the notion of experiential knowledge leads to two challenges for social scientists.     

The concept of the gene in psychiatric genetics and its consequences for the concept of mental illness

At this point in time, it is hard to say which consequences for the concept of mental illness result from modern genetics. Current research projects are trying to find significant statistical correlations between the diagnosis of a disease and a gene locus or an endophenotype. Up until now, there has not been any identification of alleles or mutations causing mental illness. In the meantime, the relations between the genetic basis and the disease are given the term “genetic vulnerability” as a placeholder; this concept simplifies the complex relations between the DNA and even the simplest cell functions observed in modern genetics. According to complex gene models like the systemic theory of DNA, it will not be possible to identify the genetic factors without a precise knowledge of the factors which modulate the gene expression. The significance of genetics as part of the concept of mental illness will not be able to be defined without further progress in developmental biology and psychology. Currently, psychological theory fails to acknowledge the complexity of the relationship between the DNA and the environment. Some starting points from which to develop such an understanding can be received from “developmental studies” and studies of the “psychophylogenesis”. An interdisciplinary concept of the biological basis of the psyche is needed.     

The Conceptual Incoherence of “Culture” in American Sociology

The meaning of the concept “culture” as used in American sociology is incoherent. Despite the advances and maturing of cultural sociology, the central idea of “culture” itself remains conceptually muddled. This article demonstrates this critical point by analyzing the definitions, meanings, and uses of the word “culture” in the field of cultural sociology’s most significant, recent edited volumes, handbooks, readers, companions, annual review chapters, and award-winning books and journal articles. Arguing for the scholarly importance of conceptual coherence, this article calls for more disciplined and cooperative theoretical work to clarify and move toward a more standardized meaning of “culture” in American sociology.
