This chapter is about the interpretation of parameters. Parameter interpretation in the stochastic actor-oriented model is difficult for two reasons. The first, shared with the conditional multinomial logit model on which it is based, is the non-linearity of the link function. The second is the unobserved nature of the sequence of ministeps, the small network changes connecting the consecutive network measurements. The chapter starts with the basics of parameter interpretation in this model and continues with interpretation of parameters specific for actor attributes; for such parameters, the selection plot is presented, a graphical possibility for interpretation. The last section presents three kinds of effect sizes.
This chapter introduces new ways to make arguments visible, audible, or tangible in the digital humanities, from sound studies to multimodal argumentation to mapping, archaeological reconstructions, and generative art.
Artificial intelligence (AI) can rapidly process large ecological datasets, uncover patterns, and inform conservation decisions, but responsible adoption depends as much on human-centric skills as on technical methods. Ecologists face steep learning curves, an overwhelming and fast-evolving model landscape, uneven access to data and computing, and a growing transparency deficit. These challenges require human-centric skills like time management, critical thinking, collaboration, communication, creativity, and project management to select, implement, interpret, and responsibly translate AI outputs into ecological insight and action. We led a workshop, EcoViz+AI: Visualization and AI for Ecology, that brought together 35 experts to synthesize practical guidance for navigating these challenges across the AI pipeline. Using workshop discussions and experiences as a foundation, this position paper proposes practical solutions and complementary human-centric skill development to address these challenges: (1) educational resources that support opportunity-cost reasoning (time management) and methodological judgment (critical thinking), (2) communities of practice that build inclusive shared expertise (collaboration and mentorship), (3) effective visualizations that improve interpretability and strengthen transparency of model behavior and uncertainty (creativity and communication), and (4) computational resources that reduce implementation burden through shared data, extensible code, and accessible infrastructure (project management and problem-solving). Our workshop compiled resources, including science communication videos for five AI use cases and repositories for ecology-related AI models and communities of practice. Emphasizing human-centric skills and working in tandem with efforts to promote open science and computational literacy can make AI in ecology more rigorous, equitable, and ecologically relevant, advancing research and conservation.
In this golden age of astronomy, the sky is full of riveting objects: white dwarves, neutron stars. But nothing has captured the same wide attention as black holes, for mathematics, physics, astronomy, and the history and philosophy of science as well as photography and art. Type in quotes “philosophy of black holes” into a search engine and you will get seminars, conferences, books; “philosophy of neutron stars” and you find “no results.” In 2015, a group of us from across disciplines began formulating a center where the various disciplines could join forces to approach these perplexing objects. In 2016, the Black Hole Initiative (BHI) at Harvard brought the approaches together. April 2019 saw the publication by the Event Horizon Telescope (EHT) of the first image of a black hole, M87*. Looking ahead, the next-generation EHT launched “History, Philosophy, Culture” as one principal scientific working group. Studies of responsible telescope siting, foundations of black hole science, algorithm/inference and visualization, and scientific collaboration became focal points. Now new challenges are emerging here, including a NASA small explorer mission to detect and measure the photon ring. Perhaps there is a new model integrating history, philosophy, and culture into science in real time.
Revelation in Christianity means the divine disclosure of events that are otherwise inaccessible to human beings. But if no one was present to see them happen, how can the faithful know what they looked like? Since the late Middle Ages, images have worked in various ways with sacred texts, such as the Bible, the Lives of Saints, and devotional books, in bringing miracles and mythic events into visually accessible form. The works of artists have also aided the interpretation of difficult texts, such as prophetic and apocalyptic books of the Bible. In this study, David Morgan examines the art of seeing things and explores how art has played a key role in the creative production and interpretation of visions and apparitions. Traversing a long stretch of historical development, he offers new insights into a significant cultural history of European Christianity from the late Middle Ages to the twentieth century.
When the row and column variables consist of the same category in a two-way contingency table, it is called a square contingency table. Since square contingency tables have an association structure due to the concentration of observed values near the main diagonal, a primary objective is to examine symmetric relationships and transitions between variables. Various models and measures have been proposed to analyze these structures to understand the changes between two variables’ behavior at two-time points or cohorts. This is necessary for a detailed investigation of individual categories and their interrelationships, such as shifts in brand preferences. We propose a novel approach to correspondence analysis (CA) for evaluating departures from symmetry in square contingency tables with nominal categories, using a modified divergence statistic. This approach ensures that well-known divergence statistics can also be visualized and regardless of the divergence statistics used, the CA plot consists of two principal axes with equal contribution rates. Notably, the scaling of the departures from symmetry provided by the modified divergence statistic is independent of sample size, allowing for meaningful comparisons and unification of results across different tables. Confidence regions are also constructed to enhance the accuracy of the CA plot.
We present ASP Chef Mustache, an extension of ASP Chef that enhances template-based rendering of answer set programming (ASP) solutions using a logic-less templating system inspired by Mustache. Our approach integrates data visualization frameworks such as Tabulator, Chart.js, and vis.js, enabling interactive representations of ASP interpretations as tables, charts, and graphs. Mustache queries in templates support advanced constructs for formatting, sorting, and multi-stage expansion, facilitating the generation of rich, structured outputs. We demonstrate the power of this framework through a series of use cases, including data analysis for the Italian VQR, visualization of blocking sets in graphs, and scheduling problems. The result is a versatile tool for bridging declarative problem solving and modern web-based visual analytics.
Playwright and teacher Migdalia Cruz was among the first participants in María Irene Fornés’s Hispanic Playwrights in Residence Laboratory at INTAR in the early 1980s. In the decades since, Cruz has become not only one of the most influential Latina playwrights in the United States but also a central figure in guiding new generations of writers, scholars, and artists through the foundational principles and practices of the Fornés playwriting method. Here, Cruz balances the reflective impulse of memoir with the more didactic priorities of instruction as, first, she outlines core principles of Fornés’s pedagogy (including direct quotations from some of Fornés’s teaching sessions in italics) before guiding the reader through an in-depth demonstration of a representative Fornés playwriting exercise, followed by some optional homework for future writing sessions.
Chapter 10 focuses on the time scale of art history, which spans centuries or even millennia. It begins by showing how art historical processes can be interpreted in terms of complex dynamic systems. It then discusses patterns of art historical change, from linear to stepwise to metastable change. The chapter addresses the question of continuity and discontinuity in art history from both quantitative and qualitative perspectives. Finally, it discusses how the concepts and methods of network theory can help us to understand the complex dynamics of artworlds.
Once the data are collected and cleaned, we can start to explore features of the network. Taking an initial look at descriptive network statistics is a good way to take an overview of the data and to spot red flags that signal a problem with the data entry or cleaning. The earlier these can be identified, the better. This chapter serves as a tutorial for using R to do so using the igraph package. It introduces the process of importing a data file into R and walks through the first things you might do with the data, including computing descriptive statistics of the structural features, integrating substantive features of nodes and links, and visualizing the network.
In epidemiological investigations, pathogen genomics can provide insights and test epidemiological hypotheses that would not have been possible through traditional epidemiology. Tools to synthesize genomic analysis with other types of data are a key requirement of genomic epidemiology. We propose a new ‘phylepic’ visualization that combines a phylogenomic tree with an epidemic curve. The combination visually links the molecular time represented in the tree to the calendar time in the epidemic curve, a correspondence that is not easily represented by existing tools. Using an example derived from a foodborne bacterial outbreak, we demonstrated that the phylepic chart communicates that what appeared to be a point-source outbreak was in fact composed of cases associated with two genetically distinct clades of bacteria. We provide an R package implementing the chart. We expect that visualizations that place genomic analyses within the epidemiological context will become increasingly important for outbreak investigations and public health surveillance of infectious diseases.
Realistic networks are rich in information. Often too rich for all that information to be easily conveyed. Summarizing the network then becomes useful, often necessary, for communication and understanding but, being wary, of course, that a summary necessarily loses information about the network. Further, networks often do not exist in isolation. Multiple networks may arise from a given dataset or multiple datasets may each give rise to different views of the same network. In such cases and more, researchers need tools and techniques to compare and contrast those networks. In this chapter, In this chapter, well show you how to summarize a network, using statistics, visualizations, and even other networks. From these summaries we then describe ways to compare networks, defining a distance between networks for example. Comparing multiple networks using the techniques we describe can help researchers choose the best data processing options and unearth intriguing similarities and differences between networks in diverse fields.
Type 2 diabetes (T2DM) poses a significant public health challenge, with pronounced disparities in control and outcomes. Social determinants of health (SDoH) significantly contribute to these disparities, affecting healthcare access, neighborhood environments, and social context. We discuss the design, development, and use of an innovative web-based application integrating real-world data (electronic health record and geospatial files), to enhance comprehension of the impact of SDoH on T2 DM health disparities.
Methods:
We identified a patient cohort with diabetes from the institutional Diabetes Registry (N = 67,699) within the Duke University Health System. Patient-level information (demographics, comorbidities, service utilization, laboratory results, and medications) was extracted to Tableau. Neighborhood-level socioeconomic status was assessed via the Area Deprivation Index (ADI), and geospatial files incorporated additional data related to points of interest (i.e., parks/green space). Interactive Tableau dashboards were developed to understand risk and contextual factors affecting diabetes management at the individual, group, neighborhood, and population levels.
Results:
The Tableau-powered digital health tool offers dynamic visualizations, identifying T2DM-related disparities. The dashboard allows for the exploration of contextual factors affecting diabetes management (e.g., food insecurity, built environment) and possesses capabilities to generate targeted patient lists for personalized diabetes care planning.
Conclusion:
As part of a broader health equity initiative, this application meets the needs of a diverse range of users. The interactive dashboard, incorporating clinical, sociodemographic, and environmental factors, enhances understanding at various levels and facilitates targeted interventions to address disparities in diabetes care and outcomes. Ultimately, this transformative approach aims to manage SDoH and improve patient care.
This chapter introduces data-driven research methods for theatre and performance. Drawing on two case studies, the chapter demonstrates how to define and identify data, how to collect and organize it, and how to analyse it through computational methods. Careful attention is paid to the tension between a rigorous data model and the uncertainty and ‘messiness’ present in data’s sources. The conclusion promotes data-driven thinking as a way to expand the context and scope of TaPS analyses and to encourage explicit reflection on the mental categories and models within which we understand performance.
Despite admonitions to address attrition in experiments – missingness on Y – alongside best practices designed to encourage transparency, most political science researchers all but ignore it. A quantitative literature search of this journal – where we would expect to find the most conscientious reporting of attrition – shows low rates of discussion of the issue. We suspect that there is confusion on the link between when attrition occurs and the type of validity it threatens when present, and limited connection to and guidance on which estimands are threatened by different attrition patterns. This is all exacerbated by limited tools to identify, investigate, and report patterns attrition. We offer the R package – attritevis – to visualize attrition over time, by intervention, and include a step-by-step guide to identifying and addressing attrition that balances post hoc analytical tools with guidance for revising designs to ameliorate problematic attrition.
The Gaia mission DR3 provides accurate data of around two billion stars in the Galaxy, including a classification based on astronomical classes of objects. In this work we present a web visualization tool to analyze one of the products published in the DR3, the Outlier Analysis Self-Organizing Map†.
The article is devoted to computer modeling, visualization, and synthesis of a digital antenna array used for transmitting and receiving signals in industrial applications. The paper proposes an iterative method for the amplitude-phase synthesis of an antenna array according to the requirements for the envelope of the side lobes. The proposed method allows to determine the complex amplitudes of the elements of a digital antenna array for any given weight function, based on the theorems of matrix theory. The difference of the method lies in the iterative procedure for choosing the weight function, taking into account the excess level of the side lobes of the digital antenna array. In this regard, in the course of solving the synthesis problem, a weight function was found that leads to the fulfilment of the requirements for radiation patterns and does not lead to a decrease in the directivity coefficient. The signal-to-noise ratio was used as a criterion. For the first time, an analytical expression is given for the formation of a weight function in the course of an iterative process that takes into account the requirements for the envelope of the side lobes. The operability and convergence of the proposed method was confirmed in the course of numerical studies on the example of a digital antenna array. The performed numerical analysis confirmed the effectiveness of the proposed synthesis method.
Large-scale multiplex tissue analysis aims to understand processes such as development and tumor formation by studying the occurrence and interaction of cells in local environments in, for example, tissue samples from patient cohorts. A typical procedure in the analysis is to delineate individual cells, classify them into cell types, and analyze their spatial relationships. All steps come with a number of challenges, and to address them and identify the bottlenecks of the analysis, it is necessary to include quality control tools in the analysis workflow. This makes it possible to optimize the steps and adjust settings in order to get better and more precise results. Additionally, the development of automated approaches for tissue analysis requires visual verification to reduce skepticism with regard to the accuracy of the results. Quality control tools could be used to build users’ trust in automated approaches. In this paper, we present three plugins for visualization and quality control in large-scale multiplex tissue analysis of microscopy images. The first plugin focuses on the quality of cell staining, the second one was made for interactive evaluation and comparison of different cell classification results, and the third one serves for reviewing interactions of different cell types.
In those moments, or seconds, or hours, when focus on our creative work overrides input from the outside world, we are in the altered state of a creative trance. Shaped by individual experiences, social circumstances, and cultural traditions, the creative trance is multifaceted and psychologically significant. Taking numerous forms throughout the sciences, arts, sports, and self-transformation, it can change the world. At age sixteen, Albert Einstein’s visualization of riding on a light beam became a basis for his theory of special relativity. It can also be the inner deliberations of both Mozart and Shostakovich, who composed finished music in their minds. Cross-culturally, meditation and sleep are central to a creative trance. The Native North American Chippewa weave dream images into their beadwork and banners. In addition to the trance of creation, there is an audience creative trance of reception that ranges from pleasant enjoyment to the overwhelming response of the Stendhal syndrome.
