A clarified typology of core-periphery structure in networks

Core-periphery structure, the arrangement of a network into a dense core and sparse periphery, is a versatile descriptor of various social, biological, and technological networks. In practice, different core-periphery algorithms are often applied interchangeably despite the fact that they can yield inconsistent descriptions of core-periphery structure. For example, two of the most widely used algorithms, the k-cores decomposition and the classic two-block model of Borgatti and Everett, extract fundamentally different structures: The latter partitions a network into a binary hub-and-spoke layout, while the former divides it into a layered hierarchy. We introduce a core-periphery typology to clarify these differences, along with Bayesian stochastic block modeling techniques to classify networks in accordance with this typology. Empirically, we find a rich diversity of core-periphery structure among networks. Through a detailed case study, we demonstrate the importance of acknowledging this diversity and situating networks within the core-periphery typology when conducting domain-specific analyses.

The Matrix

The fat body of insects has always been compared functionally to the liver of vertebrates. Both synthesize and store glycogen and lipid and are concerned with the formation of blood proteins. The comparison becomes even more apt with the discovery of microbodies and the localization of urate oxidase and catalase in insect fat body.The microbodies are oval to spherical bodies about 1μ across with a depression and dense core on one side. The core is made of coiled tubules together with dense material close to the depressed membrane. The tubules may appear loose or densely packed but always intertwined like liquid crystals, never straight as in solid crystals (Fig. 1). When fat body is reacted with diaminobenzidine free base and H2O2 at pH 9.0 to determine the distribution of catalase, electron microscopy shows the enzyme in the matrix of the microbodies (Fig. 2). The reaction is abolished by 3-amino-1, 2, 4-triazole, a competitive inhibitor of catalase. The fat body is the only tissue which consistantly reacts positively for urate oxidase. The reaction product is sharply localized in granules of about the same size and distribution as the microbodies. The reaction is inhibited by 2, 6, 8-trichloropurine, a competitive inhibitor of urate oxidase.

Martin Marty

I propose that the notion of possession adds an important ideological nuance to the analyses of iconic books set forth by Martin Marty (1980) and, more recently, by James Watts (2006). Using the early second century BCE book of Sirach as a case study, I tease out some of the symbolic dynamics through which the Bible achieved iconic status in the first place, that is, the conditions in which significance was attached to its material, finite shape. For Ben Sira, this symbolism was deeply tied to his honor-shame ethos in which women posed a threat to the honor of his eternal name, a threat resolved through his possession of Torah figured as the Woman Wisdom. What my analysis suggests is that the conflicted perceptions of gender in Ben Sira’s text is fundamental to his appropriation of, and attempt to produce, authoritative religious literature, and thus essential for understanding his relationship to this emerging canon. Torah, conceived as female, was the core of this canon, but Ben Sira adds his own literary production to this female “body” (or feminized corpus, if you will), becoming the voice of both through the experience of perfect possession.

Developing an understanding of monetary policy in LICs must start with the evidence. This chapter briefly reviews the challenges facing the empirical researcher in SSA, including scarce and inaccurate data, short policy regimes that make powerful inference difficult, and the lack of structural models to help interpret the data. It provides an overview of Chapters 4–6, which take three very different approaches to looking at these data: a broad search for cross-country stylized facts (Chapter 4), a detailed case study of a major monetary policy event (Chapter 5), and an examination of whether vector auto-regressions (VARs)—the workhorse empirical tool in this area—are likely to yield useful results in the SSA context (Chapter 6).

The Core

In this article, we explore how the discourses around gender are evolving at the core of Brazilian politics. Our focus lies on the discourses at the public hearing on the bill 3.492/19, which aimed at including “gender ideology” on the list of heinous crimes. We aim to identify the deputies’ linguistic representation of social actors as pertaining to in- and outgroups. In addition, the article analyzes through Critical Discourse Analysis how the terminology gender is represented in this particular hearing. The analysis shows how some of the conservative parliamentarians give a clearly negative meaning to the term gender, by labeling it “gender ideology” and additionally connecting it with heinous crimes. We propose that the re-signification of “gender ideology,” from rhetorical invention to heinous crime, is not only an attempt to undermine scientific gender studies but also a way for conservative deputies to gain more political power.

Course Of Study

The current study explores the multifaceted and entwined structure of constraints and spaces of the possibilities of moving ahead among the Dooms of Jammu, India, where the possibilities of upward mobility through education as a means have been observed. Interviews and detailed case study were done with eight cases. Four overlapping super-ordinate themes developed during the course of study: (a) challenges of different generation learners, (b) lack of different forms of capital, (c) dis-identification from own and emulating others and (d) mushrooming of hybrid and mimic generation. The participants experienced the very process of change and continuity through education in their lives. It is observed that education helped in converting the morphology of their existing structure. Each of the interviewee has some exclusive experiences to share, offering significant insights into their lives, struggles and their conditions. The results indicate that the first-generation learners have to face many obstacles. The study concludes that education gives better results under certain circumstances. The chances of low caste children performing better are higher if the educational institutions run with mixed batches with students belonging to all the sections of the society.

Abstract There are growing efforts to mine public and common-sense semantic network databases for engineering design ideation stimuli. However, there is still a lack of design ideation aids based on semantic network databases that are specialized in engineering or technology-based knowledge. In this study, we present a new methodology of using the Technology Semantic Network (TechNet) to stimulate idea generation in engineering design. The core of the methodology is to guide the inference of new technical concepts in the white space surrounding a focal design domain according to their semantic distance in the large TechNet, for potential syntheses into new design ideas. We demonstrate the effectiveness in general, and use strategies and ideation outcome implications of the methodology via a case study of flying car design idea generation.

The Core

In this paper, I address the case of a corporate society in Central Mexico. After volcanic eruptions triggered population displacements in the southern Basin of Mexico during the first and fourth centuries A.D., Teotihuacan became a multiethnic settlement. Groups from different backgrounds settled primarily on the periphery of the metropolis; nevertheless, around the core, intermediate elites actively fostered the movement of sumptuary goods and the arrival of workers from diverse homelands for a range of specialized tasks. Some of these skilled craftsmen acquired status and perhaps economic power as a result of the dynamic competition among neighborhoods to display the most lavish sumptuary goods, as well as to manufacture specific symbols of identity that distinguished one neighborhood from another, such as elaborate garments and headdresses. Cotton attire worn by the Teotihuacan elite may have been one of the goods that granted economic importance to neighborhood centers such as Teopancazco, a compound that displayed strong ties to the Gulf Coast where cotton cloth was made. The ruling elite controlled raw materials that came from afar whereas the intermediate elite may have been more active in providing other sumptuary goods: pigments, cosmetics, slate, greenstone, travertine, and foreign pottery. The contrast between the corporate organization at the base and top of Teotihuacan society and the exclusionary organization of the neighborhoods headed by the highly competitive intermediate elite introduced tensions that set the stage for Teotihuacan’s collapse.
