Close and Distant Reading Visualizations for the Comparative Analysis of Digital Humanities Data

Jänicke, Stefan 06 July 2016 (has links)
Traditionally, humanities scholars carrying out research on a specific or on multiple literary work(s) are interested in the analysis of related texts or text passages. But the digital age has opened possibilities for scholars to enhance their traditional workflows. Enabled by digitization projects, humanities scholars can nowadays reach a large number of digitized texts through web portals such as Google Books or Internet Archive. Digital editions exist also for ancient texts; notable examples are PHI Latin Texts and the Perseus Digital Library. This shift from reading a single book “on paper” to the possibility of browsing many digital texts is one of the origins and principal pillars of the digital humanities domain, which helps developing solutions to handle vast amounts of cultural heritage data – text being the main data type. In contrast to the traditional methods, the digital humanities allow to pose new research questions on cultural heritage datasets. Some of these questions can be answered with existent algorithms and tools provided by the computer science domain, but for other humanities questions scholars need to formulate new methods in collaboration with computer scientists. Developed in the late 1980s, the digital humanities primarily focused on designing standards to represent cultural heritage data such as the Text Encoding Initiative (TEI) for texts, and to aggregate, digitize and deliver data. In the last years, visualization techniques have gained more and more importance when it comes to analyzing data. For example, Saito introduced her 2010 digital humanities conference paper with: “In recent years, people have tended to be overwhelmed by a vast amount of information in various contexts. Therefore, arguments about ’Information Visualization’ as a method to make information easy to comprehend are more than understandable.” A major impulse for this trend was given by Franco Moretti. In 2005, he published the book “Graphs, Maps, Trees”, in which he proposes so-called distant reading approaches for textual data that steer the traditional way of approaching literature towards a completely new direction. Instead of reading texts in the traditional way – so-called close reading –, he invites to count, to graph and to map them. In other words, to visualize them. This dissertation presents novel close and distant reading visualization techniques for hitherto unsolved problems. Appropriate visualization techniques have been applied to support basic tasks, e.g., visualizing geospatial metadata to analyze the geographical distribution of cultural heritage data items or using tag clouds to illustrate textual statistics of a historical corpus. In contrast, this dissertation focuses on developing information visualization and visual analytics methods that support investigating research questions that require the comparative analysis of various digital humanities datasets. We first take a look at the state-of-the-art of existing close and distant reading visualizations that have been developed to support humanities scholars working with literary texts. We thereby provide a taxonomy of visualization methods applied to show various aspects of the underlying digital humanities data. We point out open challenges and we present our visualizations designed to support humanities scholars in comparatively analyzing historical datasets. In short, we present (1) GeoTemCo for the comparative visualization of geospatial-temporal data, (2) the two tag cloud designs TagPies and TagSpheres that comparatively visualize faceted textual summaries, (3) TextReuseGrid and TextReuseBrowser to explore re-used text passages among the texts of a corpus, (4) TRAViz for the visualization of textual variation between multiple text editions, and (5) the visual analytics system MusikerProfiling to detect similar musicians to a given musician of interest. Finally, we summarize our and the collaboration experiences of other visualization researchers to emphasize the ingredients required for a successful project in the digital humanities, and we take a look at future challenges in that research field.

Integrating Problem Solvers from Analogous Markets in New Product Ideation

Franke, Nikolaus, Poetz, Marion K., Schreier, Martin January 2014 (has links) (PDF)
Who provides better inputs to new product ideation tasks: problem solvers with expertise in the area for which new products are to be developed, or problem solvers from "analogous" markets that are distant but share an analogous problem or need? Conventional wisdom appears to suggest that target market expertise is indispensable, which is why most managers searching for new ideas tend to stay within their own market context even when they do search outside their firms' boundaries. However, in a unique symmetric experiment that isolates the effect of market origin, we find evidence for the opposite: Although solutions provided by problem solvers from analogous markets show lower potential for immediate use, they demonstrate substantially higher levels of novelty. Also compared to established novelty drivers, this effect appears highly relevant from a managerial perspective: we find that including problem solvers from analogous markets vs. the target market accounts for almost two thirds of the well-known effect of involving lead users instead of average problem solvers. This effect is further amplified when the analogous distance between the markets increases, i.e., when searching in far vs. near analogous markets. Finally, results indicate that the analogous market effect is particularly strong in the upper tail of the novelty distribution, which again underscores the effect's practical importance. All this suggests that it might pay to systematically search across firm-external sources of innovation that were formerly out of scope for most managers. (authors' abstract)

Nuclear Magnetic Resonance with the Distant Dipolar Field

Corum, Curtis A. January 2005 (has links)
Distant dipolar field (DDF)-based nuclear magnetic resonance is an active research area with many fundamental properties still not well understood. Already several intriguing applications have developed, like HOMOGENIZED and IDEAL spectroscopy, that allow high resolution spectra to be obtained in inhomogeneous fields, such as in-vivo. The theoretical and experimental research in this thesis concentrates on the fundamental signal properties of DDF-based sequences in the presence of relaxation (T1 and T2) and diffusion. A general introduction to magnetic resonance phenomenon is followed by a more in depth introduction to the DDF and its effects. A novel analytical signal equation has been developed to describe the effects of T2 relaxation and diffusing spatially modulated longitudinal spins during the signal build period of an HOMOGENIZED cross peak. Diffusion of the longitudinal spins results in a lengthening of the effective dipolar demagnetization time, delaying the re-phasing of coupled anti-phase states in the quantum picture. In the classical picture the unwinding rate of spatially twisted magnetization is no longer constant, but decays exponentially with time. The expression is experimentally verified for the HOMOGENIZED spectrum of 100mM TSP in H2O at 4.7T. Equations have also been developed for the case of multiple repetition steady state 1d and 2d spectroscopic sequences with incomplete magnetization recovery, leading to spatially varying longitudinal magnetization. Experimental verification has been accomplished by imaging the profile. The equations should be found generally applicable for those interested in DDF-based spectroscopy and imaging.

Encountering Distant Suffering: The Culture, Production, and Outcomes of Transnational Immersion Trips on the U.S.-Mexico Border

Adler, Gary John Jr. January 2012 (has links)
Short-term international immersion travel connects participants from educational and religious organizations with distant suffering to build solidarity and motivate transnational civic action. It is a distinct form of transnational social action that produces a personalized, embodied experience of transformation. Despite increasing popularity, and increasing evidence that this form of travel can facilitate civic action and activism, the mechanisms behind the production, experience, and outcomes are not well known. This research examines these issues through a focus on multiple cultural processes. The research site is BorderLinks, a faith-affiliated organization that promotes immigration awareness through travel along the U.S.-Mexico border. I use participant observation with different groups (colleges, seminaries, churches), pre/post surveys with 180 participants, and interviews with participants to examine why individuals participate, how transformative experience is produced, how group styles stabilize this moment of unsettledness, the difficulties of solidarity formation, and the specific patterns of outcomes. Short-term international immersion travel is a cultural strategy of transformation that provides participants with identity shaping experiences and fits the goals of feeder organizations that prioritize personal transformation and social engagement. Recruitment through feeder organizations creates groups with distinct demographic profiles, motivational repertoires, and emotional orientations: the "toolkits of travel." An immersion trip sits in a liminal space of culture, yet the institutional origins of groups generate group styles that guide groups through this unsettledness (Eliasoph and Lichterman 2003). Some groups "sleuth" while others "story build," resulting in different imaginations of possible future action. The encounter with migrants addresses a central question of how solidarity between international travelers and distant suffering is formed. I show the importance of two strategies of solidarity, one relational and one imaginative. Through a hike in the desert, I show the conditions for producing evoking symbols that moralize the experience into the future. I examine change in economic behavior, attitudes, and some civic activity. I use Qualitative Comparative Analysis to show which aspects of immersion travel are most responsible for change: emotional intensification, moralized situations, cognitive awareness, and/or group affiliation. For participants' narrative construction, differences in group use of reflexivity resources affect the moral extension into the future.

Eskenazi, Ednalva Maria de Sousa 04 February 2011 (has links)
Objetivos: Verificar o nível de conhecimento basal sobre práticas de promoção da saúde bucal e mensurar os ganhos de conhecimento e a habilidade de aconselhamento de alunos do quinto ano do curso de medicina. Métodos: 148 alunos, divididos em quatro turmas 2007-A (grupo controle), 2007-B, 2008-A e 2008-B , receberam intervenções progressivas de ensino, presenciais (em 2007) e a distância (em 2008). A turma 2008-B recebeu também contatos ativos com especialista em promoção bucal. O ganho de conhecimento foi medido por provas escritas aplicadas antes e após a respectiva intervenção, e a habilidade de aconselhar foi avaliada por meio de exame clínico objetivo estruturado por estações (OSCE). Resultados: 92% dos alunos não consideravam adequado o seu nível basal de conhecimento em promoção da saúde bucal. O ganho de conhecimento das turmas 2008-A e 2008-B foi progressivo, e estatisticamente superior ao do grupo controle, assim como ocorreu com a habilidade de aconselhamento da turma 2008-B. Conclusão: O desempenho do grupo 2008-B foi significativamente superior àquele dos demais grupos / Objectives: The verification of the level of basal knowledge of 5th year medical students regarding the practice of oral health promotion and to measure growth in knowledge and the capability to advise. Method: 148 students, divided into 4 teams 2007-A (control group), 2007-B, 2008 e 2008-B received progressive teaching interventions, in presence (2007) and in distance (2008). The team 2008-B also received active contacts with a specialist in promoting oral. The growth in knowledge was measured by written tests applied before and after the respective intervention, and the capability to advise was assessed through the Objective Structured Clinical Examination per stations (OSCE). Results: 92% of the students found their initial base knowledge of oral health promotion insufficient. The growth in knowledge of teams 2008-A and 2008-B was considerable when compared to the control group. Team 2008-B also demonstrated an increased capability to advise on oral health. Conclusion: The performance of 2008-B group was significantly higher than all other groups

Multi-channel Sales Distribution- Should Online Retailers Expand Offline?

SJÖLANDER, REBECCA, LANGEGGER, LENA January 2013 (has links)
The retail industry is in a motion of fascinating developments, it can be currently alleged that it is one of the most innovating fields within research. Online retailing in particular has experienced major changes in recent years. However, these developments are slowing down as online retailing is entering a mature state. Online fashion companies now have to consider new strategies to further evolve their businesses. Innovative Online companies have taken action towards a multi-channel sales distribution strategy, some have even gone as far as adopting an omni-channel approach. With that statement, this study attempts to add different insights to the topic by focusing on the issue of online expanding offline from a company point of view. Empirical data included company and industry specialist interviews as well as a questionnaire that was used for pre-research and developing propositions. This resulted in three findings that involved both advantages and disadvantages in Online fashion retailers evolving offline. Firstly, whether or not an Online fashion company should expand offline depends entirely on the ambition level and type of company interviewed. Secondly, it can be concluded that Online fashion companies have the desire to keep their current business model, though they cannot continue with the same strategy in the long run. Lastly, if an offline presence is established, a traditional expansion strategy cannot be used, but innovative concepts are required (mixed realities). If this strategy is taken seriously, expanding offline could be the solution to reach a higher level of online retailing and company success. / Program: Master Programme in Fashion Management
