Pilot Data Information Literacy Competencies Matrix Scaffolded Across Undergraduate, Graduate And Data Steward Levels, Megan R. Sapp Nelson

Libraries Faculty and Staff Scholarship and Research

Initial work in identifying data management or data information literacy skills went as far as identifying a list of proposed competencies without further differentiation between those competencies, whether by discipline, complexity, or use case. This article describes a significant innovation upon existing competencies by identifying a scaffolding (built upon existing competencies) that moves students progressively from undergraduate training through post graduate coursework and research to post-doctoral work and into the early years of data stewardship. The scaffolding ties together existing research that has been completed in research data management skills and data information literacy with research into the outcomes that …

Virtual V1sion: A Collaborative Coding Project, Cheryl Olman

MODVIS Workshop

Virtual V1sion is a new idea for fostering modeling collaborations and data sharing. While still in its infancy, the ultimate goal is a website that hosts repositories for (1) interchangeable model elements, (2) datasets that can be fit/predicted by those models, and (3) educational modules that explain the background for both the models and the datasets. The scope of the modeling is limited to predictions of V1 responses, although not all computations represented by model elements in Virtual V1sion are required to be V1-intrinsic: a goal of the project is to provide a framework in which predictions for modulation by …

A Neural Circuit For Visual Information Spreading, Gregory Francis

MODVIS Workshop

I describe a neural circuit made of integrate-and-fire neurons that instantiates a mechanism for the spreading of visual information. The circuit is simple and operates at a reasonable time scale with reasonable parameter values. Slight alterations to the anatomy allow the circuit to spread information across surfaces (constrained by the surface boundaries) as for brightness and color effects or across a group/object (as for some attention effects).

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd

MODVIS Workshop

Lightness matching data from disk-annulus experiments has the form of a parabolic (2^nd-order polynomial) function when matches are plotted against annulus luminance on log-log axes. Rudd (2010) has proposed a computational cortical model to account for this fact and has subsequently (Rudd, 2013, 2014, 2015) extended the model to explain data from other lightness paradigms, including staircase-Gelb and luminance gradient illusions (Galmonte, Soranzo, Rudd, & Agostini, 2015). Here, I re-analyze parametric lightness matching data from disk-annulus experiments by Rudd and Zemach (2007) and Rudd (2010) for the purpose of further testing the model and to try to constrain …

Figure-Ground Organization Using 3d Symmetry, Aaron Michaux, Vijai Jayadevan, Edward Delp, Zygmunt Pizlo

MODVIS Workshop

We present a novel approach to object localization using mirror symmetry as a general purpose and biologically motivated prior. 3D symmetry leads to good segmentation because (i) almost all objects exhibit symmetry, and (ii) configurations of objects are not likely to be symmetric unless they share some additional relationship. Furthermore, psychophysical evidence suggests that the human vision system makes use symmetry in constructing 3D percepts, indicating that symmetry may be important in object localization. No general purpose approach is known for solving 3D symmetry correspondence in 2D camera images, because few invariants exist. Therefore, to test symmetry as a clustering …

A Mixture Model Demonstrates Use Of Distinct Strategies In A Global Motion Direction Task, Lanya Tianhao Cai, Benjamin T. Backus

MODVIS Workshop

Mixture models are well known in cognitive psychology, less so in vision. Are there cases where the data allow clear testing as to whether different strategies are employed in a task? Most psychophysical measurements manipulate a single staircase variable to map out a monotonic increasing function, but if performance is limited by different mechanisms over the range of the variable, classical fitting could be inappropriate. We present a data set and analyses that confirm the presence of two visual strategies addressing the same task, with the choice of strategies depending on the staircase variable. In a net-motion discrimination task, stimuli …

Choice-Dependent Perceptual Biases, Long Luu, Alan A. Stocker

MODVIS Workshop

The perceived motion direction of a dynamic random dot stimulus is systematically biased when preceded by a motion discrimination task (Jazayeri and Movshon, 2007). The biases were originally thought to occur because subjects mistakenly reuse the neural read-out optimized for the discrimination task when forming the percept (Fig.1a, Task-dependent model). In a series of experiments, we demonstrated that this explanation is incorrect and that the biases actually result from the conditioning of the percept on the preceding discrimination judgment (Fig1.b, Choice-dependent model). Experiment 1 was aimed at replicating the biases for an orientation stimulus. Subjects first indicated whether the stimulus …

A Learning Model For L/M Specificity In Ganglion Cells, Albert Ahumada

MODVIS Workshop

An unsupervised learning model for developing L/M specific wiring at the ganglion cell level would support the research indicating L/M specific wiring at the ganglion cell level (Reid and Shapley, 2002). Removing the contributions to the surround from cells of the same cone type improves the signal-to-noise ratio of the chromatic signals. The unsupervised learning model used is Hebbian associative learning, which strengthens the surround input connections according to the correlation of the output with the input. Since the surround units of the same cone type as the center are redundant with the center, their weights end up disappearing. This …

Focusing On Selection For Fixation, John K. Tsotsos, Calden Wloka, Yulia Kotseruba

MODVIS Workshop

Building on our presentation at MODVIS 2015, we continue in our quest to discover a functional, computational, explanation of the relationship among visual attention, interpretation of visual stimuli, and eye movements, and how these produce visual behavior. Here, we focus on one component, how selection is accomplished for the next fixation. The popularity of saliency map models drives the inference that this is solved; we suggested otherwise at MODVIS 2015. Here, we provide additional empirical and theoretical arguments. We then develop arguments that a cluster of complementary, conspicuity representations drive selection, modulated by task goals and history, leading to a …

Learning Object Representations For Modeling Attention In Real World Scenes, Alex Schwarz, Frederik Beuth, Fred H. Hamker

MODVIS Workshop

Models of visual attention have been rarely used in real world tasks as they have been typically developed for psychophysical setups using simple stimuli. Thus, the question remains how objects must be represented to allow such models an operation in real world scenarios. We have previously presented an attention model capable of operating on real-world scenes (Beuth, F., and Hamker, F. H. 2015, NCNC, which is a successor of Hamker, F. H., 2005, Cerebral Cortex), and show here how its object representations have been learned. We have used a learning rule based on temporal continuity (Földiák, P., 1991, Neural Computation) …

The Empathy Project: Using A Project-Based Learning Assignment To Increase First-Year College Students’ Comfort With Interdisciplinarity, Micol Hutchison

Interdisciplinary Journal of Problem-Based Learning

Empathy and interdisciplinarity are both concepts that are current and relevant—across professions, in research, and in academia. This paper describes a large, interdisciplinary, project-based assignment, the Empathy Project, which allows students to delve into and increase comfort and skill with interdisciplinary thinking and collaborative learning, while improving the core college skills of written and oral communication, ethical and quantitative reasoning, and critical thinking. As I revised the assignment based on student feedback and results, I found that group conferences and time in class to work collaboratively were beneficial. Additionally, building increased scaffolding into the assignment, including greater student and group …

Make The Connection: Personal And Institutional Identity In The U.S. Department Of Veterans Affairs Ptsd Campaign, Staci B. Smith

Open Access Theses

The common procedure in a health campaign is to use fear and guilt appeals to influence health behaviors among target populations (Mattson & Lam, 2016). The use of identity, identification, and reframing in a health campaign has been relatively under-explored. This study examines invitations to identification and reframing in a specific health campaign, the U.S. Department of Veterans Affairs (VA) “Make the Connection” campaign. With the issues of mental health and post-traumatic stress disorder (PTSD) reaching high levels of attention in media and society, the VA’s Make the Connection campaign encourages military veterans and their families to seek help for …

Quit Playing With Your Watch: Perceptions Of Smartwatch Use, Christopher M. Gaeta

Purdue Polytechnic Masters Theses

This study identified perceptions and social norms that may affect smartwatch adoption. Interviews were conducted to identify perceptions of smartwatch use and norms that might affect those perceptions. Smartwatch use was found to activate norms associated with wristwatch use – specifically, smartwatch users’ peers took offense to the users looking at their wristwatches. This study also found that norms prevent the use of smartwatches’ voice controls in public and various perceptions of smartwatch use and ownership.

Sexual Minority Health: A Bibliography And Preliminary Study Of The Book Literature, Sharon A. Weiner

Libraries Faculty and Staff Scholarship and Research

The literature on the health of lesbian, gay, bisexual, transgender, and intersexual (LGBT) people appears in many types of resources and disciplines. To begin to address the need for relevant, easily accessible information for LGBT people and health care providers, this study identified popular and scholarly books published in the past 10 years and analyzed topics; number of books published per year; more prolific authors; and primary publishers. The results indicated that a relatively small number of books were published (521) by a wide range of publishers/self-publishers. Most were about mental health, relationships, or family and 24% were personal accounts.
