© 2018 VLDB Endowment. In order to democratize data science, we need to fundamentally rethink the current analytics stack, from the user interface to the "guts." Most importantly, enabling a broader range of users to unfold the potential of (their) data requires a change in the interface and the "protection" we offer them. On the one hand, visual interfaces for data science have to be intuitive, easy, and interactive to reach users without a strong background in computer science or statistics. On the other hand, we need to protect users from making false discoveries. Furthermore, it requires that technically involved (and often boring) tasks have to be automatically done by the system so that the user can focus on contributing their domain expertise to the problem. In this paper, we present Northstar, the Interactive Data Science System, which we have developed over the last 4 years to explore designs that make advanced analytics and model building more accessible.

This article reports on one stage of a project that considered twenty 8–12-years-olds use of Virtual Reality (VR) for entertainment. The entire project considered this in relation to interaction and engagement, health and safety and how VR play fitted into children's everyday home lives. The specific focus of this article is solely on children's interaction and engagement with a range of VR content on both a low-end and high-end head mounted display (HMD). The data were analysed using novel multimodal methods that included stop-motion animation and graphic narratives to develop multimodal means for analysis within the context of VR. The data highlighted core design elements in VR content that promoted or inhibited children's storytelling in virtual worlds. These are visual style, movement and sound which are described in relation to three core points of the user's journey through the virtual story; (1) entering the virtual environment, (2) being in the virtual story world, and (3) affecting the story through interactive objects. The findings offer research-based design implications for the improvement of virtual content for children, specifically in relation to creating content that promotes creativity and storytelling, thereby extending the benefits that have previously been highlighted in the field of interactive storytelling with other digital media.

In this article, we identify the contributions to narrative approaches that emerge from a communication perspective. We elaborate on an approach to narrative that centers on the joint, interactive aspects of narrative construction and discuss why it is useful for navigating around two pitfalls encountered by narrative scholars: (1) the psychologist's fallacy and (2) the problems of finalization in narrative.

"Socrates once complained in the Protagoras that eloquent orators and books are alike in that they provide massive amounts of information, "but if one asks any of them an additional question . . . they cannot either answer or ask a question on their own account." As I wrote this book, my challenge was to see to what degree I could provide a counterexample to Socrates' claim. Of course, Socrates is correct: There is no substitute for live philosophical conversations and debates. However, as you get acquainted with this book, you will find that it does ask you questions and provokes you to ask questions in turn. Instead of simply presenting information for you to passively absorb, its many exercises require your active involvement, and some will even provide the opportunity for you to dialogue with your friends about the philosophical issues discussed. For this reason, I chose the title The Philosophical Journey: An Interactive Approach"--

The dissertation 'Interactive Approaches to Rural Development' gives new theoretical and empirical knowledge in the collaboration on development of rural areas and landscapes. From a perspective about the development and the challenges faced, the study analyses which functions that are demanded by the rural areas. Furthermore, the study makes an analysis of the collaboration in an EU financed rural development association; the Local Action Group (LAG). The overall objective is to: Analyse and discuss approaches to rural development under Danish conditions. The dissertation is cantered around three papers introduced with a frame that contributes to the overall objective. With point of departure in the changes that have structured the Danish landscape, the first paper analyses and discusses how the Danish planning system can be optimized to plan for a multifunctional landscape. Paper two and three builds on the EU rural development policy LEADER that through local project based development supports new income opportunities for the local inhabitants. Collaboration on the rural development is a subject that requires an interdisciplinary analytical approach. The dissertation therefore builds on different theories and both qualitative and quantitative analytical methods. The theoretical foundation draws on generic network theory and various applications of this. This is conducted by inclusion of ideas from interorganisational interaction in an analysis of the collaboration between municipality and a locally anchored development association. In addition the theory of social capital is applied to analyse whether the partnership formation and collaboration has supported the development of the local area. Furthermore, the concept of multifunctionality is assessed as a principle to be applied in countryside planning and rural development. The empirical foundation of the dissertation draws on mixed method research approach with interviews and surveys that are studied through qualitative and quantitative data analyses. Two of the three papers take point of departure in a case study of LAG-Djursland. Based on the dissertation it is concluded, that a crucial factor in the development of rural areas and landscapes is the collaboration among relevant stakeholders– often arranged around a partnership. To secure a concrete and locally attuned development it is important to engage local anchored stakeholders. These stakeholders have the greatest knowledge about the local development opportunities and barriers. Though the dissertation builds on experiences from the Danish rural landscape, the analyses, discussions and conclusions will be relevant in an international perspective. The interactive approach and the analysis hereof will be applicable in other domains than that of rural development.

The priorities of dressing have broadened and become more complex over the years, creating challenges in developing new products. The technological evolu-tion allied with its democratization has provided new possibilities for experimen-tation in the area of fashion and clothing in order to meet the current complex ex-pectations. The article presents the experimental development of a transdiscipli-nary fashion product, which proposes the expansion of the communicability of dance through technological stage design. According to the metalinguistic concept allied to the computational logic pre-established in a project plan, the proposed product has, attached to a ballet costume, sensors to capture movements and transform them into light and colors with different intensities, through direct in-teraction with the movement direction and intensity. As a result, the LIGHTness project explores the forms, interactivity and light effects of ballet, emphasizing the dichotomy between strength and lightness in this type of dance. ; This project is financed by FEDER funds through the Programa Operacional Factores de Com-petitividade - COMPETE and by National Funds through FCT - Foundation for Science and Technology under the project POCI-01-0145-FEDER-007136. ...

The relevance of local knowledge in cultural heritage is by now acknowledged. It helps to determine many community-based projects by identifying the material to be digitally maintained in multimedia collections provided by communities of volunteers, rather than for-profit businesses or government entities. Considering that the search and browsing of texts, images, video, and 3D models related to places is more essential than using a simple text-based search, an interactive multimedia map was implemented in this study. The map, which is loaded on a single HyperText Markup Language (HTML) page using AJAX (Asynchronous JavaScript and XML), with a client-side control mechanism utilising jQuery components that are both freely available and ad-hoc developed, is updated according to user interaction. To simplify the publication of geo-referenced information, the application stores all the data in a Geographic JavaScript Object Notation (GeoJSON) file rather than in a database. The multimedia contents—associated with the selected Points of Interest (PoIs)—can be selected through text search and list browsing as well as by viewing their previews one by one in a sequence all together in a scrolling window (respectively: "Table", "Folder", and "Tile" functions). PoIs—visualised on the map with multi-shape markers using a set of unambiguous colours—can be filtered through their categories and types, accessibility status and timeline, thus improving the system usability. The map functions are illustrated using data collected in a Comenius project. Notes on the application software and architecture are also presented in this paper.

The project investigates the possibility of visualizing open source data in a 3D interactive virtual environment. We propose a new tool, 'ViBe'. We programmed 'ViBe' using Unity for its compatibility with HTC VIVE glasses for virtual reality (VR). ViBe offers an abstract visualization of open source data in a 3D interactive environment. The ViBe environment entails three main topics a) inhabitants, b) environmental factors, and c) land-use; acting as representatives of parameters for cities and urban design. Berlin serves as a case study. The data sets used are divided according to Berlin's twelve administrative districts. The user immerses into the virtual environment where they can choose, using the HTC Vive controllers, which district (or Berlin as a whole) they want information for and which topics they want to be visualized, and they can also teleport back and forth between the different districts. The goal of this project is to represent different urban parameters an abstract simulation where we correlate the corresponding data sets. By experiencing the city through visualized data, ViBe aims to provide the user with a clearer perspective onto the city and the relationship between its urban parameters. ViBe is designed for adults and kids, urban planners, politicians and real estate developers alike.

Democracies do not take up arms against each other. Although this axiom has attained the status of a mantra in the field of international relations, this statement is much more complex than it appears, in part because it is highly contingent on the definitions and operationalizations of both democracy and conflict. This article revisits democratic peace theory, combining both institutional constraints and similarity-based arguments. Interactions between the democratic level of the dyad (the average democratic level of its members) and its democratic spread (difference between the democratic scores of its members) create a dyadic triangle that encompasses all possible combinations of cases, revisiting which dyads are more prone to conflict. The findings partially confirm and partially refute both the institutional constraints and the similarity-based arguments, leading to a nuanced alternative theory: the Interactive Model of Democratic Peace. Akin to democratic peace theory, our evidence shows that the higher a dyad's level of democracy is, the lower the probability of fatal militarized interstate disputes between that pair of states. However, contrary to democratic peace theory, we find that dissimilar-regime dyads can still be peaceful as long as they have a high mean of democracy. Following the theory of regime similarity, we consider the democratic spread of each dyad, but we find that being similar is not a sufficient condition for peace between the members of a dyad. From the empirical evidence, the article derives three heuristic zones of conflict, filling much of the gray area that has been left unexplained by previous models.
