This paper presents GlamMap, a visualization tool for large, multi-variate georeferenced humanities data sets. Our approach visualizes the data as glyphs on a zoomable geographic map, and performs clustering and data aggregation at each zoom level to avoid clutter and to prevent overlap of symbols. GlamMap was developed for the Galleries, Libraries, Archives, and Museums (GLAM) domain in cooperation with researchers in philosophy. We demonstrate the usefulness of our approach by a case study on history of logic, which involves navigation (...) and exploration of 7100 bibliographic records, and scalability on a data set of sixty million book records.

We propose a novel type of low distortion radial embedding which focuses on one specific entity and its closest neighbors. Our embedding preserves near-exact distances to the focus entity and aims to minimize distortion between the other entities. We present an interactive exploration tool SolarView which places the focus entity at the center of a "solar system" and embeds its neighbors guided by concentric circles. SolarView provides an implementation of our novel embedding and several state-of-the-art dimensionality reduction and embedding techniques, (...) which we adapted to our setting in various ways. We experimentally evaluated our embedding and compared it to these state-of-the-art techniques. The results show that our embedding competes with these techniques and achieves low distortion in practice. Our method performs particularly well when the visualization, and hence the embedding, adheres to the solar system design principle of our application. Nonetheless - as with all dimensionality reduction techniques - the distortion may be high. We leverage interaction techniques to give clear visual cues that allow users to accurately judge distortion. We illustrate the use of SolarView by exploring the high-dimensional metric space of bibliographic entity similarities. (shrink)

Social epistemologists should be well-equipped to explain and evaluate the growing vulnerabilities associated with filter bubbles, echo chambers, and group polarization in social media. However, almost all social epistemology has been built for social contexts that involve merely a speaker-hearer dyad. Filter bubbles, echo chambers, and group polarization all presuppose much larger and more complex network structures. In this paper, we lay the groundwork for a properly social epistemology that gives the role and structure of networks their due. In particular, (...) we formally define epistemic constructs that quantify the structural epistemic position of each node within an interconnected network. We argue for the epistemic value of a structure that we call the (m,k)-observer. We then present empirical evidence that (m,k)-observers are rare in social media discussions of controversial topics, which suggests that people suffer from serious problems of epistemic vulnerability. We conclude by arguing that social epistemologists and computer scientists should work together to develop minimal interventions that improve the structure of epistemic networks. (shrink)

This paper presents the current state of development of GlamMap, a visualisation tool that displays library metadata on an interactive, computer-generated geographic map. The focus in the paper is on the most crucial improvement achieved in the development of the tool: GlamMapping Trove. The visualisation of Trove’s sixtymillion book records is possible thanks to an improved database structure, more efficient data retrieval, and more scalable visualisation algorithms. The paper analyses problems encountered in visualising massive datasets, describes remaining challenges for the (...) tool, and presents a use case demonstrating GlamMap’s ability to serve researchers in the history of ideas.

In this paper, we explain and showcase the promising methodology of testimonial network analysis and visualization for experimental epistemology, arguing that it can be used to gain insights and answer philosophical questions in social epistemology. Our use case is the epistemic community that discusses vaccine safety primarily in English on Twitter. In two studies, we show, using both statistical analysis and exploratory data visualization, that there is almost no neutral or ambivalent discussion of vaccine safety on Twitter. Roughly half the (...) accounts engaging with this topic are pro-vaccine, while the other half are con-vaccine. We also show that these two camps rarely engage with one another, and that the con-vaccine camp has greater epistemic reach and receptivity than the pro-vaccine camp. In light of these findings, we question whether testimonial networks as they are currently constituted on popular fora such as Twitter are living up to their promise of delivering the wisdom of crowds. We conclude by pointing to directions for further research in digital social epistemology. (shrink)

In this position paper, we describe a number of methodological and philosophical challenges that arose within our interdisciplinary Digital Humanities project CatVis, which is a collaboration between applied geometric algorithms and visualization researchers, data scientists working at OCLC, and philosophers who have a strong interest in the methodological foundations of visualization research. The challenges we describe concern aspects of one single epistemic need: that of methodologically securing (an increase in) trust in visualizations. We discuss the lack of ground truths in (...) the (digital) humanities and argue that trust in visualizations requires that we evaluate visualizations on the basis of ground truths that humanities scholars themselves create. We further argue that trust in visualizations requires that a visualization provides provable guarantees on the faithfulness of the visual representation and that we must clearly communicate to the users which part of the visualization can be trusted and how much. Finally, we discuss transparency and accessibility in visualization research and provide measures for securing transparency and accessibility. (shrink)

Libraries provide access to large amounts of library metadata. Unfortunately, many libraries only offer textual interfaces for searching and browsing their holdings. Visualizations provide simpler, faster, and more efficient ways to navigate, search and study large quantities of metadata. This paper presents GlamMap, a visualization tool that displays library metadata on an interactive, computer-generated geographic map. We provide detailed discussion of how GlamMap benefits the work of librarians and researchers. We show how geographic representations help librarians to perform tasks such (...) as collection assessment and how geographic information helps researchers to identify important scientific resources.

Beauchamp and Childress’ definition of autonomous decision‐making includes the conditions of intentionality, understanding, and non‐control. In genetics, however, a relational conception of autonomy has been increasingly recognized. This article aims to empirically assess aspects of social influence in genetic testing decision‐making and to connect these with principlist and relational theories of autonomy. We interviewed 18 adult genetic counsellees without capacity issues considering predictive genetic testing for cancer predisposition for themselves and two counselling physicians in Switzerland. We conducted a qualitative analysis, (...) building on a grounded theory study about predictive genetic testing decision‐making. We found that some participants agreed to predictive genetic testing predominantly because relatives wanted them to do it, with some even acting contrary to their own convictions. Others, in contrast, based their decision on purely individualistic reasons but expressed difficulties in explaining their decision to their social environment. Healthcare professionals had a critical influence on decision‐making in many cases without being manipulative, as perceived by counsellees. Still, cases of coercion and social pressure occurred within social relationships. In conclusion, predictive genetic testing decision‐making includes relational and individualistic aspects, and both are compatible with autonomous decision‐making. While the principlist and relational notions of autonomy compete on a theoretical level, they are two sides of the same coin when used as analytical lenses for genetic testing decision‐making. Social acceptance of refusal of testing should be improved to mitigate social pressure. Individuals should be encouraged to decide for themselves how much their social environment influences their decision regarding predictive genetic testing. (shrink)

Although lie detection procedures have been fundamentally criticized since their inception at the beginning of the 20th century, they are still in use around the world. In addition, they have created some remarkable appeal in the context of counterterrorism policies. Thereby, the links between science and fiction in this topic are quite tight and by no means arbitrary: In the progressive narrative of the lie detection devices, there is a promise of changing society for the better, which is entangled in (...) a fictional narrative provided by many cinematic and literary examples. By drawing on the concept of “diegetic technologies” formulated by David Kirby, we want to highlight the role of science fictional narratives in the historical development and current application of lie detection procedures. We therefore aim to use this conceptual frame to analyze the role of prevention-oriented mind reading procedures, which are developed for or already used in the “war on terror” with reference to their fictional predecessors. One virulent factor has to be highlighted in this context: The fictional engagement with possible new lie detection practices is in itself creating a legitimating ground for future security technologies.

The term ‘locked-in’ syndrome (LIS) describes a medical condition in which persons concerned are severely paralyzed and at the same time fully conscious and awake. The resulting anarthria makes it impossible for these patients to naturally communicate, which results in diagnostic as well as serious practical and ethical problems. Therefore, developing alternative, muscle-independent communication means is of prime importance. Such communication means can be realized via brain–computer interfaces (BCIs) circumventing the muscular system by using brain signals associated with preserved cognitive, (...) sensory, and emotional brain functions. Primarily, BCIs based on electrophysiological measures have been developed and applied with remarkable success. Recently, also blood flow–based neuroimaging methods, such as functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS), have been explored in this context. After reviewing recent literature on the development of especially hemodynamically based BCIs, we introduce a highly reliable and easy-to-apply communication procedure that enables untrained participants to motor-independently and relatively effortlessly answer multiple-choice questions based on intentionally generated single-trial fMRI signals that can be decoded online. Our technique takes advantage of the participants’ capability to voluntarily influence certain spatio-temporal aspects of the blood oxygenation level–dependent (BOLD) signal: source location (by using different mental tasks), signal onset and offset. We show that healthy participants are capable of hemodynamically encoding at least four distinct information units on a single-trial level without extensive pretraining and with little effort. Moreover, realtime data analysis based on simple multi-filter correlations allows for automated answer decoding with a high accuracy (94.9%) demonstrating the robustness of the presented method..

Goal-setting theory states that challenging, specific, and concrete goals (i.e., subordinate goals) are powerful motivators and boost performance in goal pursuit more than vague or abstract goals (i.e., superordinate goals). Goal-setting theory predominantly focuses on single, short-term goals and less on broad, long-term challenges. This review article extends goal-setting theory and argues that superordinate goals also fulfill a crucial role in motivating behavior, particularly when addressing broad, long-term challenges. The purpose of this article is to show theoretically that people pursue (...) long-term goals more successfully when they focus on subordinate and superordinate goals simultaneously than when they focus on either subordinate or superordinate goals alone.

This article is concerned with Klee’s belief that ‘intuition’ is indispensable to the artistic and scientific understanding of natural processes and laws of nature. Examples of his pictorial practice are discussed which derive from the as yet for the most part unpublished and little studied writings from the period at the Bauhaus. Taking the methodologically diverse literature about Klee into account, this paper tries to understand Klee’s ‘scientism’ in the cultural and theoretical context of his time.Keywords: Intuition; Genius; E. T. (...) A. Hoffmann; Wilhelm Worringer. (shrink)

The differences between the "habits of the heart" in German and U.S.-American corporations can be described by analyzing the way corporations deal with norms and values within their organizations. Whereas many U.S. corporations have introduced formal business ethics programs, German companies are very reluctant to address normative questions publicly. This can be explained by the different cultural backgrounds in both countries. By defining these different "habits of the heart" underlying German and American business ethics it is possible to show the (...) problems and questions within the intercultural management of values, but also the possible solutions.

BackgroundWhereas the majority of bereaved persons recover from their grief without professional assistance, a minority develops pathological grief reactions. Etiological models postulate that dysfunctional cognitions may perpetuate such reactions. The Grief Cognitions Questionnaire assesses thoughts after bereavement in nine interrelated domains. A short form with four domains is often used. However, an evaluation of the psychometric properties of the GCQ-SF and its utility compared to the GCQ is lacking and these instruments have not been validated in German.MethodGerman bereaved persons responded (...) to an online survey containing the GCQ, measures of grief severity, grief rumination, symptoms of depression and anxiety, and optimism and pessimism. 585 participants were included. Item analyses and confirmatory factor analyses were conducted. Correlations between the GCQ and GCQ-SF and grief rumination, optimism and pessimism assessed construct validity. Criterion-related validity was assessed by comparing whether the correlation of the GCQ with grief severity was higher than with anxious and depressive symptoms. Logistic regression and receiver-operator characteristics compared the questionnaires on their ability to predict probable prolonged grief ‘caseness’.ResultsInternal consistencies for both questionnaires were identical and excellent. Confirmatory factor analyses obtained a satisfactory fit for models with nine and four correlated subscales and respective higher-order factor models. The GCQ and the GCQ-SF correlated higher with grief severity than with other measures of psychopathology. The logistic regression showed a significant association between the GCQ-SF and prolonged grief ‘caseness’. Of the remaining subscales of the GCQ, only one subscale contributed to the prediction. The ROC analyses showed nearly identical areas under the curve.ConclusionThe translated GCQ and GCQ-SF demonstrated very good psychometric properties. The correlations with grief severity highlight the questionnaires’ clinical relevance. The questionnaires possessed identical diagnostic specificity and sensitivity. Whenever a timesaving assessment of the most typical grief-specific cognitions is important, the GCQ-SF represents an alternative to the GCQ. The original GCQ may still be superior when a more detailed description of a bereaved person’s cognitions is desirable. (shrink)

Anti-materialist thought experiments as, e.g., zombie arguments, have posed some of the most vexing problems for materialist accounts of phenomenal consciousness. I doubt, however, that arguments of this kind can refute the core thesis of materialism. Although I do not question that there is something very special about an adequate explanation of phenomenal consciousness, and although I accept the epistemic irreducibility of phenomenal consciousness, I deny that modal arguments reach far enough to establish essentialism about consciousness. I will draw upon (...) a relativistic conception of modal space and suggest to strictly separate between varieties of metaphysical possibility - depending on which world is considered as actual, and depending on accessibility relations. It is shown that the modal argument cannot endanger the reductive explanation of the mind-brain relation if one distinguishes carefully between possibility according to primary intensions and possibility according to secondary intensions . Modal arguments are strong enough to make an epistemological point but not an ontological one. (shrink)

In Willensfreiheit Geert Keil seeks a better explanation of freedom of the will by investigating the connections between free will and determinism vs. indeterminism. Keil thinks that there is no freedom of the will without declaring determinism untrue. So, on the one hand freedom of the will seems to require indeterminism, but on the other hand, freely willed choices and decisions must be different from pure chance. The key, Keil thinks, is global indeterminism without local indeterminism — I doubt this.

Mhealth technology is mushrooming world-wide and, in a variety of forms, reaches increasing numbers of users in ever-widening contexts and virtually independent from standard medical evidence assessment. Yet, debate on the broader societal impact including in particular mapping and classification of ethical issues raised has been limited. This article, as part of an ongoing empirically informed ethical research project, provides an overview of ethical issues of mhealth applications with a specific focus on implications on autonomy as a key notion in (...) the debate. A multi-stage model of references to the potential of mhealth use for strengthening some or other form of self-determination will be proposed as a descriptive tool. It illustrates an assumed continuum of enhanced autonomy via mhealth broadly conceived: from patient to user autonomy, to improved health literacy, and finally to the vision of supra-individual empowerment and democratised, participatory health and medicine as a whole. On closer examination, however, these references are frequently ambivalent or vague, perpetuating the at times uncritical use of established autonomy concepts in medical ethics. The article suggests zooming in on the range of autonomy-related aspects against the backdrop of digital innovation and datafied health more generally, and on this basis add to existing frameworks for the ethical evaluation of mhealth more specifically.

ZusammenfassungIm vorliegenden Beitrag wird vor dem Hintergrund diskursiv verhandelter Topoi über Geflüchtete untersucht, inwiefern Sportlehrkräfte geflüchtete Schüler*innen als ‚Andere‘ wahrnehmen. Angesichts der binären Geschlechterordnung, die sowohl im Sport als auch im Diskurs um Geflüchtete reproduziert wird, liegt der Schwerpunkt hierbei auf der geschlechterbezogenen Konstruktion von ‚Anderssein‘. Dafür werden der Forschungsstand und konstruktivistische und postkoloniale Theoriebezüge skizziert sowie 31 Interviews mit Sportlehrkräften unter einem diskursanalytischen Fokus ausgewertet. Die Befunde legen nahe, dass der Umgang mit geflüchteten Schüler*innen mit dem Normalitätsverständnis der Interviewten (...) und der Institution Schule bricht. Darüber hinaus lassen sich fluchtbezogene Konstruktionsmuster erkennen, die durch die Körperzentrierung des Sportunterrichts besonders aktualisiert und von den Befragten geschlechtstypisierend und kulturell ausgedeutet werden.

Numerous studies argue that perceived group deprivation is a risk factor for radicalization and violent extremism. Yet, the vast majority of individuals, who experience such circumstances do not become radicalized. By utilizing models with several interacting risk and protective factors, the present analysis specifies this relationship more concretely. In a large United Kingdom nationally representative survey, we examine the effects of group-based relative deprivation on violent extremist attitudes and violent extremist intentions, and we test whether this relationship is contingent upon (...) several individual differences in personality. The results show that stronger group-based injustices lead to increased support for and intentions to engage in violent extremism. However, some of the effects are much stronger for individuals who exhibit a stronger need for uniqueness and for status and who demonstrate higher levels of trait entitlement. Conversely, several effects are lessened for those individuals high in trait forgiveness, demonstrating a strong capacity for self-control and for those who are exerting critical as well as open-minded thinking styles, thus constituting buffering protective factors, which dampen the adverse effects of perceived group injustice on violent extremism. The results highlight the importance of considering the interaction between individual dispositions and perceptions of contextual factors the conditional and cumulative effects of various risk and protective factors and the functional role of protective factors when risk factors are present. Collectively, these findings bring us one step closer to understanding who might be more vulnerable to violent extremism as well as how. Overall, the study suggests that preventing and countering violent extremism programs must take account of the constellation of multiple factors that interact with one another and which can be targeted in preventions strategies.
