The central aim of this paper is to present a Boolean algebraic approach to the classical Aristotelian Relations of Opposition, namely Contradiction and (Sub)contrariety, and to provide a 3D visualisation of those relations based on the geometrical properties of Platonic and Archimedean solids. In the first part we start from the standard Generalized Quantifier analysis of expressions for comparative quantification to build the Comparative Quantifier Algebra CQA. The underlying scalar structure allows us to define the Aristotelian relations in Boolean terms (...) and to propose a 3D visualisation by transforming a cube into an octahedron. In part two, the architecture of the CQA is shown to carry over, both to the classical quantifiers of Predicate Calculus and to the modal operators—which are given a Generalized Quantifier style re-interpretation. In this way we provide an algebraic foundation for Blanché’s Aristotelian hexagon as well as a 3D alternative to his 2D star-like visualisation. In a final part, a richer scalar structure is argued to underly the realm of Modality, thus generalizing the 3D algebra with eight (2 3 ) operators to a 4D algebra with sixteen (2 4 ) operators. The visual representation of the latter structure involves a transformation of the hypercube to a rhombic dodecahedron. The resulting 3D visualisation allows a straightforward embedding, not only of the classical Blanché star of Aristotelian relations or the paracomplete and paraconsistent stars of Béziau (Log Investig 10, 218–232, 2003) but also of three additional isomorphic Aristotelian constellations.

Studying via the Internet using information tools is a common activity for students in higher education. With students accessing their subject material via the Internet, studies have shown that students have difficulty understanding the complete purpose of an assessment which leads to poor information search practices. The selection of relevant information for particular learning assessments is the topic of this paper as it describes a case study that focuses on the information tool use of a small group of participants and (...) is a continuation of similar research studies. The study and discussed research findings point to the benefit of students use of a visualisation tool to provide relevant learning cues and to transition to improved engagement with online assessment.

This paper argues that spacetime visualisability is not a necessary condition for the intelligibility of theories in physics. Visualisation can be an important tool for rendering a theory intelligible, but it is by no means a sine qua non. The paper examines the historical transition from classical to quantum physics, and analyses the role of visualisability and its relation to intelligibility. On the basis of this historical analysis, an alternative conception of the intelligibility of scientific theories is proposed, based on (...) Heisenberg 's reinterpretation of the notion of Anschaulichkeit. (shrink)

This essay explores a series of issues which have emerged around the term ‘visualisation’ asa result of materials generated out of the international Lord of the Rings audience project.‘Visualisation’ is quite widely used as a term in film studies, but not much considered. In this essay I begin from someelements of empirical evidence, and through some unlikely encounters that these spurredwith bodies of work from outside film studies, I develop an argument for a new approach tothinking about ‘visualisation’. This approach (...) would reach a long way and have wideimplications, not least for the ways we think about and research film audiences, and for theways we approach adaptation studies. Therefore the essay is as much a report on a journeyof ideas, and a set of proposals, asit is a claim to a demonstration. (shrink)

The main point developed in this paper is the demonstration of the attitudes characterizing the major Belgian political parties. This is achieved through a factorial analysis applied to a set of data resulting from the answers given by the major parties leaders to various specific questions regarding bath the prevailing economie as well as institutional issues at the eve of the election of December 17th, 1978. From that point it has been possible to compare those results with the one obtained (...) from the data concerning the 1974 programmes.The results of the statistical analysis show that white in 1974 the strongest positive associations between parties corresponded to tht traditional ethical and socioeconomic cleavages, four years later the linguistic dimension was predominant with a stronger homogeneity characterizing the Dutchspeaking group than what could be observed for the Frenchspeaking one.The factorial analysis allows for a graphical representation of the respective positioning of the parties along the statistically significant factorial axes. Applied to two sets of data, the first one on purely institutional matters, the second one on both institutional and economic policies, the analysis reveals clearly through the various graphs presented the linguistic cleavage as well as the divergences about the extent of regional competences and minorities protection, on the one hand, and, on the other hand, the degrees of regional economic autonomy and of public intervention in the business life.

The Harold Pinter Archive at the British Library contains correspondence dating from 1977 to 2008, including his e-mail archive. In total, the correspondence strand of the archive contains c.20,000 paper letters and c.3500 e-mails. This project used data analytics (in Python) and network visualisation (in Gephi) to interrogate the ways in which digital and analogue correspondence function together within Pinter’s literary archive. The attendant paper reflects upon what this analysis might mean for archivists, curators and researchers working with hybrid correspondence (...) collections in the context of Digital Humanities and Artificial Intelligence based research methodologies. The paper includes an analysis of what an email is both materially and functionally—what are its constituent parts and in what ways is it like and unlike a physical letter, as well as a discussion of how we can leverage the highly structured nature of e-mail data to our advantage using computational techniques, and the limitations of these approaches to socalled “dark archives”. Network visualisations are used to represent correspondence visually in order to shed light on the activities it represents; particularly literary collaboration and administration. The paper concludes with an attempt to draw conclusions from these analyses and to think about their implications for repositories and researchers collecting and using hybrid correspondence collections. The Python code produced for the project is collection agnostic and available under a Creative Commons Licence, meaning that any collecting repository holding email archives in MBOX format can use it to extract GDPR compliant metadata from their collections and visualise them in Gephi.

Mammalian vomeronasal receptors respond to pheromones conveying information on gender, reproductive status and individual recognition. The question arises as to how this information is coded, which parts of the code require combinatorial activity and whether or not there are specific receptor neurons committed to sex discrimination. Are there receptor neurons that are committed to responding for female or male pheromones? Is there a sex difference for the proportion of these receptors, bearing in mind that it is very much in the (...) male's interest to distinguish the restricted oestrous phase of the female's cycle in order to successfully mate? Perhaps more intriguing is the complexity of individual recognition and whether or not the vomeronasal receptors actually possess this capacity. A recent paper in Science1 by Ron Yu and colleagues addresses these issues by literally visualising patterns of activity in VNO slices and determining what information is common across different individuals and what distinguishes them.

Correspondence held in the collections of cultural institutions is an important resource for researchers, including historians, biographers, and social scientists. Email has been the dominant form of correspondence for the last 30 years and email archives are now being acquired by cultural institutions as a valuable resource for their collections. There are challenges in collecting, preserving and providing access to email archives, as with all born-digital materials, but also challenges in using email archives as a researcher. One tool that can (...) help researchers use an email archive is visualisation. Visualisation has been applied to email for a long period of time but there has been little research into the visualisation needs of researchers using email archives. The preliminary outcomes of a research project investigating the needs of researchers suggests that visualisations will be useful to the researcher, who is always under the pressure of limited time, to work efficiently with the email archive. Artificial intelligence (AI) can play a role in preparing the email archive for visualisation. However, the research outcomes suggest that visualisations will be viewed cautiously by researchers who want time with the actual email archive to develop their research and they are unlikely to trust visualisations alone. The use of AI in the production of visualisations has the potential to add further barriers to researchers’ level of trust. (shrink)

The surviving pictorial hagiographical cycles of St Panteleimon were executed in the period between the 10th and 15th centuries. The most elaborate one is on a vita icon, consisting of sixteen scenes, at the monastery of St Catherine, Mt. Sinai and is at the centre of this research. The painter used the Passion of St Panteleimon by Symeon Metaphrastes as a main textual source for its creation. In addition, we may presume that the iconography of the images was influenced by (...) other existing pictorial cycles of the life of the saint. Also, the selection of the images, included in the saint's cycle, reflects the devotional needs and wishes of the unknown donor. (shrink)

Modelling that exploits visual elements and information visualisation are important areas that have contributed immensely to understanding and the computerisation advancements in many domains and yet remain unexplored for the benefit of the law and legal practice. This paper investigates the challenge of modelling and expressing structures and processes in legislation and the law by using visual modelling and information visualisation (InfoVis) to assist accessibility of legal knowledge, practice and knowledge formalisation as a basis for legal AI. The paper uses (...) a subset of the well-defined Unified Modelling Language (UML) to visually express the structure and process of the legislation and the law to create visual flow diagrams called lawmaps, which form the basis of further formalisation. A lawmap development methodology is presented and evaluated by creating a set of lawmaps for the practice of conveyancing and the Landlords and Tenants Act 1954 of the United Kingdom. This paper is the first of a new breed of preliminary solutions capable of application across all aspects, from legislation to practice; and capable of accelerating development of legal AI. (shrink)

The article proposes systematisation and development of the discourse of the East European methodological traditions regarding application of the systematic approach as a way of subject localisation in psychological research. In particular, the author’s version of systematic localisation of psychological research subjects by means of structural and ontological visualisations has been developed. The procedure proposed for systematic localisation of the researched subject includes four subsequent stages: 1) fixation of the borders and structure of the ontological field which is being studied; (...) 2) segment analysis of the obtained structure; 3) study of specifics and contents of structural and functional ties; 4) visual mapping of genesis of the core processes. The article describes specifics of application of systematic localisation of the subject of research at the example of such researched object as personal socialisation. (shrink)

The eleventh-century Indian Buddhist master Ratnākaraśānti presents a unique Yogācāra interpretation of tantric _maṇḍala_ visualisation in the _*Guhyasamājamaṇḍalavidhiṭīkā_. In this text, he employs the neither-one-nor-many argument to assert that the qualities of the mind represented by the deities in the _maṇḍala_ are neither the same nor different from the mind itself. He also provides five scenarios of meditation to explain the necessity of practising both the perfection method (_pāramitānaya_) and the mantra method (_mantranaya_) together in Mahāyāna. Ratnākaraśānti’s explanation exerts a (...) significant influence on the works of later Buddhist masters in India and Tibet, with parts of it being reused in the _*Śrīherukopadeśanāmasvādhiṣṭhānakrama_ by Śūnyasamādhivajra (c. the eleventh century), the eighteenth chapter of the _Āmnāyamañjarī_ by Abhayākaragupta (from the late eleventh to the twelfth century) and the tantric compendium _sNgags rim chen mo_ by the Tibetan master Tsong kha pa Blo bzang grags pa (1357–1419). This paper explores how Ratnākaraśānti’s explanation has been reused and modified in these subsequent works. While Śūnyasamādhivajra faithfully reproduced Ratnākaraśānti’s Yogācāra explanation, Abhayākaragupta modified it to align with his Madhyamaka view. Abhayākaragupta in turn influenced Tsong kha pa, who accepted Abhayākaragupta’s Madhyamaka modification in his works. This paper also engages with current scholarly discussions on textual reuse and the underlying reasons behind it. While Śūnyasamādhivajra and Abhayākaragupta assimilated Ratnākaraśānti’s explanation without acknowledgement, Tsong kha pa quoted the text by name and acknowledged Abhayākaragupta’s reuse of Ratnākaraśānti’s explanation. This paper concludes by discussing the factors that determine whether the reused text is acknowledged or not, and the possible reasons behind textual reuse. (shrink)

Three studies were conducted to examine the relation of spatial visualization to solving kinematics problems that involved either predicting the two‐dimensional motion of an object, translating from one frame of reference to another, or interpreting kinematics graphs. In Study 1, 60 physics‐naíve students were administered kinematics problems and spatial visualization ability tests. In Study 2, 17 (8 high‐ and 9 low‐spatial ability) additional students completed think‐aloud protocols while they solved the kinematics problems. In Study 3, the eye movements (...) of fifteen (9 high‐ and 6 low‐spatial ability) students were recorded while the students solved kinematics problems. In contrast to high‐spatial students, most low‐spatial students did not combine two motion vectors, were unable to switch frames of reference, and tended to interpret graphs literally. The results of the study suggest an important relationship between spatial visualization ability and solving kinematics problems with multiple spatial parameters. (shrink)

Traditionally, vision science and information/data visualization have interacted by using knowledge of human vision to help design effective displays. It is argued here, however, that this interaction can also go in the opposite direction: the investigation of successful visualizations can lead to the discovery of interesting new issues and phenomena in visual perception. Various studies are reviewed showing how this has been done for two areas of visualization, namely, graphical representations and interaction, which lend themselves to work on (...) visual processing and the control of visual operations, respectively. The results of these studies have provided new insights into aspects of vision such as grouping, attentional selection and the sequencing of visual operations. More generally yet, such results support the view that the perception of visualizations can be a useful domain for exploring the nature of visual cognition, inspiring new kinds of questions as well as casting new light on the limits to which information can be conveyed visually.

A new approach examined two aspects of chess skill, long a popular topic in cognitive science. A powerful computer‐chess program calculated the number and magnitude of blunders made by the same 23 grandmasters in hundreds of serious games of slow (“classical”) chess, regular “rapid” chess, and rapid “blindfold” chess, in which opponents transmit moves without ever seeing the actual position. Rapid chess led to substantially more and larger blunders than classical chess. Perhaps more surprisingly, the frequency and magnitude of blunders (...) did not differ in rapid versus blindfold play, despite the additional memory and visualization load imposed by the latter. We discuss the involvement of various cognitive processes in human problem‐solving and expertise, especially with respect to chess. Prior opposing views about the basis of general chess skill have emphasized the dominance of either (a) swift pattern recognition or (b) analyzing ahead, but both seem important and the controversy appears currently unresolvable and perhaps fruitless.

Like his contemporary, Edward Weston, Ansel Adams claimed that visualization is essential for creating fine art photography. But, unlike Weston, he believed that a print from a negative is like a performance from a score. In his analogy, a photographer’s visualization is like a musician’s composition: once it has been set down in a ‘score’, it can be expressively rendered by different performers, making it possible to create and critically appreciate ‘performances’ with different qualities. I argue that this (...) music-photography analogy makes Adams’s conception of photographic visualization more fruitful than Weston’s alternative. However, while I agree with Adams that a print is analogous to a performance, I criticize his idea that a negative is like a score. I argue that he holds a traditional, single-stage conception of photography, which led him to overlook a key distinction between undeveloped film and the developed negative. The multi-stage account of photography that I defend not only remedies this problem but also shows how Adams’s proposal can be fully realized in digital photography. Most significantly, it invites theorists and practitioners to expand the music-photography analogy by considering wider varieties of music—not only performances from a score. (shrink)

In order to solve problems, humans are able to synthesize apparently unrelated concepts, take advantage of serendipitous opportunities, hypothesize, invent, and engage in other similarly abstract and creative activities, primarily through the use of their visual systems. In _Scenario Visualization_, Robert Arp offers an evolutionary account of the unique human ability to solve nonroutine vision-related problems. He argues that by the close of the Pleistocene epoch, humans evolved a conscious creative problem-solving capacity, which he terms scenario visualization, that enabled (...) them to outlive other hominid species and populate the planet. Arp shows that the evidence for scenario visualization -- by which images are selected, integrated, and then transformed and projected into visual scenarios -- can be found in the kinds of complex tools our hominid ancestors invented in order to survive in the ever-changing environments of the Pleistocene world. Arp also argues that this conscious capacity shares an analogous affinity with neurobiological processes of selectivity and integration in the visual system, and that similar processes can be found in the activities of organisms in general. The evolution of these processes, he writes, helps account for the modern-day conscious ability of humans to use visual information to solve nonroutine problems creatively in their environments. Arp's account of scenario visualization and its emergence in evolutionary history suggests an answer to two basic questions asked by philosophers and biologists concerning human nature: why we are unique; and how we got that way. Robert Arp is Postdoctoral Research Fellow at the National Center for Biomedical Ontology. His areas of specialization include philosophy of biology and philosophy of mind. He is the author of numerous articles and the forthcoming An Integrated Approach to the Philosophy of Mind. (shrink)

The act of understanding is at the heart of all scientific activity; without it any ostensibly scientific activity is as sterile as that of a high school student substituting numbers into a formula.

In the last two decades there has been renewed interest in visualization in logic and mathematics. Visualization is usually understood in different ways but for the purposes of this article I will take a rather broad conception of visualization to include both visualization by means of mental images as well as visualizations by means of computer generated images or images drawn on paper, e.g. diagrams etc. These different types of visualization can differ substantially but I (...) am interested in offering a characterization of visualization that is as broad as possible. The article describes and explains (1) the way in which visual thinking fell into disrepute, (2) the renaissance of visual thinking in mathematics over recent decades, (3) the ways in which visual thinking has been rehabilitated in epistemology of mathematics and logic.

In this paper, I first present the ideas and arguments put forward by evolutionary psychologists that humans evolved certain capacities to creatively problem solve. Specifically, Steven Mithen thinks that creative problem solving is possible because the mind has evolved a conscious capacity he calls cognitive fluidity, the flexible exchange of information between and among mental modules. While I agree with Mithen that cognitive fluidity acts as a necessary condition for creative problem solving, I disagree that cognitive fluidity alone will suffice (...) for such an activity. I argue further that the flexible exchange of information between and among modules, as well as what I call scenario visualization - a conscious ability to segregate and integrate visual images in future scenarios - evolved in our species and accounts for certain kinds of creative problem solving.

In the field of the philosophy of mathematics, in recent years, there has been a resurgence of two processes: intuition and visualization. History has shown us that great mathematicians in their inventions have used these processes to arrive at their most brilliant proofs, theories and concepts. In this article, we want to defend that both intuition and visualization can be understood as processes that contribute to the development of mathematical knowledge as evidenced in the history of mathematics. Like (...) intuition, visualization does not have a definition, and its role has become more prominent both in pure mathematics and in educational research. For us, both visualization and intuition are processes that start from the real world of those who “intuit” or “visualize,” require experience and knowledge of concepts and theories (the more expertise in the subject, the more profound the results will be) and must, in the end, be validated by the specialized academic community. In this article, we defend the importance of visualization in mathematical practice and its role in the advances of great scientists (Euclid, Euler, Galileo, Descartes, Newton, Maxwell, Riemann, Einstein, Feynman, among others) as an alternative and valuable way to symbolic thinking, which has “reigned” in the academic and scientific community.

Visual imagination (or visualization) is peculiar in being both free, in that what we imagine is up to us, and useful to a wide variety of practical reasoning tasks. How can we rely upon our visualizations in practical reasoning if what we imagine is subject to our whims? The key to answering this puzzle, I argue, is to provide an account of what constrains the sequence in which the representations featured in visualization unfold—an account that is consistent with (...) its freedom. Three different proposals are outlined, building on theories that link visualization to sensorimotor predictive mechanisms (e.g., efference copies, forward models ). Each sees visualization as a kind of reasoning, where its freedom consists in our ability to choose the topic of the reasoning. Of the three options, I argue that the approach many will find most attractive—that visualization is a kind of off-line perception, and is therefore in some sense misrepresentational—should be rejected. The two remaining proposals both conceive of visualization as a form of sensorimotor reasoning that is constitutive of one’s commitments concerning the way certain kinds of visuomotor scenarios unfold. According to the first, these commitments impinge on one’s web of belief from without, in the manner of normal perceptual experience; according to the second, these commitments just are one’s (occurrent) beliefs about such generalizations. I conclude that, despite being initially counterintuitive, the view of visualization as a kind of occurrent belief is the most promising. (shrink)

With the rapidly growing amounts of information, visualization is becoming increasingly important, as it allows users to easily explore and understand large amounts of information. However the field of information visualiza- tion currently lacks sufficient theoretical foundations. This article addresses foundational questions connecting information visualization with computing and philosophy studies. The idea of multiscale information granula- tion is described based on two fundamental concepts: information (structure) and computation (process). A new information processing paradigm of Granular Computing enables stepwise (...) increase of granulation/aggregation of information on different levels of resolution, which makes possible dynamical viewing of data. Information produced by Google Earth is an illustration of visualization based on clustering (granulation) of information on a succession of layers. Depending on level, specific emergent properties become visible as a result of different ways of aggregation of data/information. As information visualization ultimately aims at amplifying cognition, we discuss the process of simulation and emulation in relation to cognition, and in particular visual cognition. (shrink)

Due to the large-scale mining of mineral resources, the surface strata in many areas have collapsed and even developed into deformation and subsidence. Based on the conventional geotechnical deformation monitoring technology, the surface deformation prediction and disaster caused by the conventional geotechnical deformation monitoring technology can be avoided. In this paper, based on GIS, combined with the analysis of surface settlement, the surface settlement, slope value, curvature deformation value, horizontal displacement, and corresponding horizontal deformation formula are comprehensively analyzed and studied. (...) In order to make the surface deformation visualization and realize the high approximation processing with the subsidence area, this paper innovatively introduces the 3D visualization settlement data analysis and realizes the calculation result analysis and corresponding retrieval multiple visualization in the subsidence area depth prediction process. On this basis, the prediction data of subsidence area can be optimized and analyzed so as to master the efficient and accurate law of surface deformation. In the experimental part, a mine is taken as the experimental object, and the 3D visual monitoring processing is carried out. In this paper, the main method to prevent electromagnetic leakage of the computer system is the source suppression method. The source suppression method solves the problem fundamentally by reducing or eliminating the emission of computer electromagnetic leakage source. In the actual experiment, the effect of this method is very effective. The experimental results show that the prediction results and corresponding early warning accuracy of the system are significantly improved compared with the traditional scheme, which provides practical significance for disaster prevention and corresponding environmental impact assessment.

Critical thinking about international politics often involves reasoning about the beliefs, goals, appraisals, actions, and plans of actors such as countries, governments, politicians, etc. We analyzed arguments in interpretive reports about international politics, in order to develop a prototype argument diagramming tool for this domain, AVIZE (Argument Visualization and Evaluation). The purpose of AVIZE is to aid users in the construction and self-evaluation of real-world arguments in the domain of international politics. AVIZE provides a set of argument schemes as (...) cognitive building blocks for constructing argument diagrams. Most of the schemes are related to concepts from the field of automated plan recognition in artificial intelligence.

Majority of Chinese characters are pictographic characters with strong associative ability and when a character appears for Chinese readers, they usually associate with the objects, or actions related to the character immediately.

In teaching statistics in secondary schools and at university, two visualizations are primarily used when situations with two dichotomous characteristics are represented: 2×2 tables and tree diagrams. Both visualizations can be depicted either with probabilities or with frequencies. Visualizations with frequencies have been shown to help students significantly more in Bayesian reasoning problems than probability visualizations do. Because tree diagrams or double-trees (which are largely unknown in school) are node-branch-structures, these two visualizations (compared to the 2×2 table) can even simultaneously (...) display probabilities on branches and frequencies inside the nodes. This is a teaching advantage as it allows the frequency concept to be used to better understand probabilities. However, 2×2 tables and (double-) trees have a decisive disadvantage: While joint probabilities (e.g., P(AB)) are represented in 2×2 tables but no conditional probabilities (e.g., P(A|B)), it is exactly the other way around with (double-) trees. Therefore, a visualization that is equally suitable for the representation of joint probabilities and conditional probabilities is desirable. In this article, we present a new visualization—the frequency net—in which all absolute frequencies and all types of probabilities can be depicted. In addition to a detailed theoretical analysis of the frequency net, we report the results of a study with 249 university students that shows that “net diagrams” can improve reasoning without previous instruction to a similar extent as 2×2 tables and double-trees. Regarding questions about conditional probabilities, frequency visualizations (2×2 table, double-tree, or net diagram with natural frequencies) are consistently superior to probability visualizations. The frequency net performs as well as the frequency double-tree. Only the 2×2 table with frequencies—the only visualization that participants were already familiar with —led to higher performance rates. If, on the other hand, a question about a joint probability had to be answered, all implemented visualizations clearly supported participants’ performance, and no uniform format effect becomes visible. Participants reached the highest performance in the versions with probability 2×2 tables and probability net diagrams. Furthermore, after conducting a detailed error analysis, we report interesting error shifts between the two information formats and the different visualizations and give recommendations for teaching probability.

Analysis of sites of newly integrated DNA in cellular genomes is important to several fields, but methods for analyzing and visualizing these datasets are still under development. Here, we describe tools for data analysis and visualization that take as input integration site data from our INSPIIRED pipeline. Paired-end sequencing allows inference of the numbers of transduced cells as well as the distributions of integration sites in target genomes. We present interactive heatmaps that allow comparison of distributions of integration sites (...) to genomic features and that support numerous user-defined statistical tests. To summarize integration site data from human gene therapy samples, we developed a reproducible report format that catalogs sample population structure, longitudinal dynamics, and integration frequency near cancer-associated genes. We also introduce a novel summary statistic, the UC50, which provides a single number summarizing possible clonal expansion. Using these tools, we characterize ongoing longitudinal characterization of a patient from the first trial to treat severe combined immunodeficiency-X1, showing successful reconstitution for 15 years accompanied by persistence of a cell clone with an integration site near the cancer-associated gene CCND2.
