Spatial Information Literacy For Digital Humanities: The Case Study Of Leveraging Geospatial Information For African American History Education., Nicole Kong, Cornelius Bynum, Chrystal Johnson, Jennifer Sdunzik, Xiaoyue Qin

Libraries Faculty and Staff Scholarship and Research

The rise of “digital humanities” and the “spatial turn” in the humanities has generated many new insights in the study of culture, history, literature, and arts. Within this research trend, the library's geospatial service can play an active role by introducing spatial information literacy and technology. In this article, we use the information literacy framework to explore the library's role in supporting digital humanities by introducing a successful collaboration involving a librarian and history and education researchers in hosting a National Endowment for the Humanities (NEH)-funded summer institute for school teachers. Our results suggest that the framework has opened a …

A Comparative History Of Resurrection Plants, John Charles Ryan

CLCWeb: Comparative Literature and Culture

In his article "A Comparative Literary History of Resurrection Plants" John Charles Ryan assembles a comparative history of resurrection plants through textual analysis of early botanical commentaries, herbal references, prose, poetry, and other sources. Resurrection plants include a diverse range of botanical species, typically of arid regions, that appear to come back to life after complete desiccation. Historical and contemporary observers—from sixteenth-century herbalist John Gerard to contemporary Australian poet John Kinsella—have expressed an abiding fascination for resurrection plants' capacity to survive harsh environmental conditions. The plants court their own deaths by paring down—then restoring—physiological processes in relation to shifting ecological …

The Indian Empire And Its Colonial Practices In South Asia, Yubraj Aryal

CLCWeb: Comparative Literature and Culture

In his article "The India, Empire and its Colonial Practices in South Asia" Yubraj Aryal claims that Bharatiya discourse supports colonization in South Asia. This discourse justifies oppression of institutions, practices, of the non-Bharatiya colonized. The article examines Indian Empire's colonialism toward the weaker, smaller nations along its border and the Bharatiya ideology at the heart of the repressive empire, which is taken to represent the South Asian subcontinent. The article looks at the way in which Bharatiya is perhaps a more oppressive ideology than Orientalism and gives a glimpse into how society, culture, history, and textuality work around power …

Adoption, Cynical Detachment, And New Age Beliefs In Juno And Kung Fu Panda, Fu-Jen Chen

CLCWeb: Comparative Literature and Culture

In his article "Adoption, Cynical Detachment, and New Age Beliefs in Juno and Kung Fu Panda" Fu-Jen Chen situates his study within today's prevailing climate of global consumption to argue that the 2007 film Juno—featuring an unconventional portrayal of the adoption triad and a cynical detachment from public values—not only trivializes and depoliticizes the practice of adoption but also serves as an ideological supplement to today's global capitalism. Furthermore, Kung Fu Panda 1 & 2 (2008; 2011) provide two ideological messages of contemporary New Age spirituality—"the belief in nothing" in part I, and "the attitude of inner peace" …

Wilderness Courage Scale (Wcs), Piotr Prochniak

Journal of Human Performance in Extreme Environments

This article presents a new tool—the Wilderness Courage Scale. The Wilderness Courage Scale is a scale that diagnoses undertaking activity in dangerous natural environments, despite personal fears. The validity of the Wilderness Courage Scale was tested using exploratory and confirmatory factor analyses. The results of factor analyses verified the one-factor structure. The questionnaire’s internal consistency and intercorrelations were also tested. The Wilderness Courage Scale correlates with sensation seeking, some personality traits, and coping forms. The author discusses the findings in regard to the Wilderness Courage Scale as an instrument to measure exploration of dangerous natural environments. However, further studies need …

Re-Envisioning A Traditional Liaison Library Model To Accommodate The Digital Scholarship Needs Of Users, Erla P. Heyns

Libraries Faculty and Staff Scholarship and Research

This paper is a case study of the liaison model at the Humanities, Social Science & Education Library (HSSE Library) at Purdue University. In order to integrate new digital scholarship services into the library it became apparent that a re-envisioning of the current liaison model was required.

Determining Visual Shape Features For Novel Object Classes, Yaniv Morgenstern, Filipp Schmidt, Roland W. Fleming

MODVIS Workshop

The visual representation of shape reduces a high-dimensional input into a smaller set of more informative features. These features can span a range of abstractions from shallow features based on statistical summaries of images, to deep features related to the generative causes of the shapes. Here we examined the depth of the visual system’s representation of shape by comparing human judgments of whether novel shapes appeared to belong to a common class with a range of models with different shape representations. Each shape class was based on a unique 2D base shape, formed by attaching parts of contours from different …

Real Time Learning Level Assessment Using Eye Tracking, Saurin S. Parikh, Hari Kalva

MODVIS Workshop

E-Learning is emerging as a convenient and effective learning tool. However, the challenge with eLearning is the lack of effective tools to assess levels of learning. Ability to predict difficult content in real time enables eLearning systems to dynamically provide supplementary content to meet learners’ needs. Recent developments have made possible low-cost eye trackers, which enables a new class of applications based on eye response. In comparison to past attempts using bio-metrics in learning assessments, with eye tracking, we can have access to the exact stimulus that is causing the response. A key aspect of the proposed approach is the …

Modeling Distribution Learning In Visual Search, Andrey Chetverikov

MODVIS Workshop

Chetverikov, Campana, and Kristjansson (2017) used visual search to demonstrate that human observers are able to extract statistical distributions of visual features. Observers searched for an odd-one-out target with distractors randomly drawn from the same distribution over the course of several “prime” trials. Then, on test trials parameters of the target and distractors changed and response times (RT) were analyzed as a function of the distance between the target position in feature space and the mean of distractor features during prime trials. The resulting RT curves followed the probability density of prime distractor distributions. This approach provides a detailed estimation …

Large-Scale Discovery Of Visual Features For Object Recognition, Drew Linsley, Sven Eberhardt, Dan Shiebler, Thomas Serre

MODVIS Workshop

A central goal in vision science is to identify features that are important for object and scene recognition. Reverse correlation methods have been used to uncover features important for recognizing faces and other stimuli with low intra-class variability. However, these methods are less successful when applied to natural scenes with variability in their appearance.

To rectify this, we developed Clicktionary, a web-based game for identifying features for recognizing real-world objects. Pairs of participants play together in different roles to identify objects: A “teacher” reveals image regions diagnostic of the object’s category while a “student” tries to recognize the object. Aggregating …

A Computational Account Of A Class Of Orientation Illusions, Dejan M. Todorovic

MODVIS Workshop

Contrast-dependent orientation illusions are phenomena in which the appearance of the illusion depends not only on geometrical arrangements of the constituents of illusory configurations, but also on their luminance levels. Whereas certain standard configurations may evoke strong illusory effects, their contrast-manipulated variants (configurations in which only the luminance contrast polarity of some of their elements is manipulated, while retaining the geometry of the standard versions) may show weakened or no illusory effects, or even reversed illusions. Although generally rather salient, the contrast-dependent illusions have not been researched in much detail, except for the well-known Münsterberg (Café Wall) illusion. Here I …

Modeling The Neural Circuitry Underlying The Behavioral And Eeg Correlates Of Attentional Capture, Chloe Callahan-Flintoft, Brad Wyble

MODVIS Workshop

The Reactive-Convergent Gradient Field model (R-CGF) is a unique approach to modeling spatial attention in that it links neural mechanisms to event related potentials (ERPs) from scalp EEG. This model was developed with the aim of explaining different, sometimes conflicting, findings in the attention literature. Specifically, this model address conflicting findings showing both simultaneous and serial deployment of attention. Another argument addressed by the model is whether attention to a location invokes a suppression of the spatial surround, or the selective inhibition of distractors. With the R-CGF, we have found that these results are not as incompatible as they appear …

Spatial-Temporal Visible Contrast Energy Predictions Of Detection Thresholds, Albert Ahumada, Andrew B. Watson, Jihyun Yeonan-Kim

MODVIS Workshop

The Barten (1994) spatial-temporal model was used to predict the Gabor stimulus contrast energy thresholds reported by Carney et al. (2013). The RMS error of fit was 1.6 dB, corrected for the number of parameters (6) estimated. The model has two lowpass spatial-temporal channels, combined by inhibition as in our spatial models (Watson & Ahumada, 2005; Ahumada & Watson, 2013). Computation of models predictions were greatly simplified by the spatial-temporal separability of the stimuli and the simplifications that result from using Gaussian filters in the spatial domain. The best fitting spatial filter frequency cutoffs are 11.4 and 0.88 cpd. The …

Computational Modeling Of Contrast Sensitivity And Orientation Tuning In Schizophrenia, Steven M. Silverstein, Docia L. Demmin, James A. Bednar

MODVIS Workshop

Computational modeling is being increasingly used to understand schizophrenia, but, to date, it has not been used to account for the common perceptual disturbances in the disorder. We manipulated schizophrenia-relevant parameters in the GCAL (gain control, adaptation, laterally connected) model (Stevens et al., 2013), run using the Topographica simulator (Bednar, 2012), to model low-level visual processing changes in the disorder. Our models incorporated: separate sheets for retinal, LGN, and V1 activity; gain control in the LGN; homeostatic adaptation in V1 based on a weighted sum of all inputs and limited by a logistic (sigmoid) nonlinearity; lateral excitation and inhibition in …

Information Use In Design: What Should We Be Teaching?, Amy S. Van Epps

Libraries Faculty and Staff Scholarship and Research

Librarians are regularly working to understand how students make decisions around information use to inform the development of more relevant learning activities. The more relevant the activities when students are learning any new skill, the more likely they are to understand the task and incorporate the learning into future design decisions and writing. The need to build connections and understanding is critical in adoption of information literacy. In this study, the researcher analyzed the transcript from an end of semester focus group with students in a design class about their information use during the semester project. The transcript was analyzed …

Technology From The Perspective Of Society And Public Interest, Chanwoon Park

Purdue Polytechnic Doctoral Dissertations

The ultimate goals of this study were to determine ways to reconcile technology with public interest and to understand the relationship between what we know and how we feel about technology. To achieve the goals, related literatures were reviewed; the mechanism of technology development was described with empirical data; and human perception of technology was tested with a survey. The duality of technology that implied technological inherencies of technical reason and social meanings was the principle assumption of the study. Neutrality of technology becomes a myth with the presence of social meanings embodied in technology. Given the huge impact of …

Internal And External Factors Influencing Enrollment Into An Undergraduate Arabic Language Program In Indiana: A Survey Of University Freshmen And Sophomores, Tyler J. Mallari

Purdue Polytechnic Masters Theses

Within the rankings of world languages, Arabic takes a prominent place, being the fifth most-spoken language in the world (Lane, 2016). Despite the surge of concern in modern media with relations in the Middle East, particularly in Arab-populated countries, very little focus has been put on improving enrollment in Arabic programs in the United States, and in particular in the Midwest. At Purdue University, enrollment in Arabic language courses have only been low and no effort has been made on the part of the university or the department to understand this trend from more than a purely statistical analysis of …
