Frame of Reference Interaction.

We present a unified set of 3D interaction techniques that demonstrates an alternative way of thinking about the navigation of large virtual spaces in non-immersive environments. Our alternative conceptual framework views navigation from a cognitive perspective—as a way of facilitating changes in user attention from one reference frame to another—rather than from the mechanical perspective of moving a camera between different points of interest. All of our techniques link multiple frames of reference in some meaningful way. Some techniques link multiple windows within a zooming environment while others allow seamless changes of user attention between static objects, moving objects, and groups of moving objects. We present our techniques as they are implemented in GeoZui3D, a geographic visualization system for ocean dat

Integrating Multiple 3D Views through Frame-of-reference Interaction

Frame-of-reference interaction consists of a unified set of 3D interaction techniques for exploratory navigation of large virtual spaces in nonimmersive environments. It is based on a conceptual framework that considers navigation from a cognitive perspective, as a way of facilitating changes in user attention from one reference frame to another, rather than from the mechanical perspective of moving a camera between different points of interest. All of our techniques link multiple frames of reference in some meaningful way. Some techniques link multiple windows within a zooming environment while others allow seamless changes of user focus between static objects, moving objects, and groups of moving objects. We present our techniques as they are implemented in GeoZui3D, a geographic visualization system for ocean data

Haptic Interface for Center of Workspace Interaction

We build upon a new interaction style for 3D interfaces, called the center of workspace interaction. This style of interaction is defined with respect to a central fixed point in 3D space, conceptually within arm\u27s length of the user. For demonstration, we show a haptically enabled fish tank VR that utilizes a set of interaction widgets to support rapid navigation within a large virtual space. The fish tank VR refers to the creation of a small but high quality virtual reality that combines a number of technologies, such as head-tracking and stereo glasses, to their mutual advantag

Multi-Resolution Functional ANOVA for Large-Scale, Many-Input Computer Experiments

The Gaussian process is a standard tool for building emulators for both deterministic and stochastic computer experiments. However, application of Gaussian process models is greatly limited in practice, particularly for large-scale and many-input computer experiments that have become typical. We propose a multi-resolution functional ANOVA model as a computationally feasible emulation alternative. More generally, this model can be used for large-scale and many-input non-linear regression problems. An overlapping group lasso approach is used for estimation, ensuring computational feasibility in a large-scale and many-input setting. New results on consistency and inference for the (potentially overlapping) group lasso in a high-dimensional setting are developed and applied to the proposed multi-resolution functional ANOVA model. Importantly, these results allow us to quantify the uncertainty in our predictions. Numerical examples demonstrate that the proposed model enjoys marked computational advantages. Data capabilities, both in terms of sample size and dimension, meet or exceed best available emulation tools while meeting or exceeding emulation accuracy

University student perceptions of body-worn cameras

Numerous studies have examined university student perceptions of a plethora of criminal justice related topics. However, there has been no published research on university student perceptions of, or level of support for, the relatively new body-worn camera technology. Using data collected from sample of 244 students enrolled at a midsized southeastern university, this study examined the perceptions of body-worn cameras held by university students. Demographic and educational characteristics, as well as individual level experiences, were measured for to determine their relationship with student perceptions. Findings indicated that respondents held positive attitudes of body-worn cameras. Perceived inequality in the use of force and major emerged as significant predictors of the level of support for body-worn cameras

Televising Memory: The Tenth Anniversary of 9/11

This thesis examines the formation of national memory by exploring tenth anniversary television coverage of 9/11. By analyzing themes of nationalism that structure the television specials and create a positive national memory, this thesis argues that the national memory of 9/11 serves current national goals and develops myths of American exceptionalism while it ignores the negative consequences and realities of 9/11

NURSING ORIENTATION AND EFFECT ON RETENTION IN A RURAL MEDICAL FACILITY

New graduate registered nurses (NGRNs) need post-graduate support to ease their transition into professional practice and to decrease turnover. Orientation programs have been identified as a method to increase NGRN retention, job satisfaction, and competence. With the current nursing shortage, it is essential to maintain NGRNs in the profession, especially since they encompass the largest population of nurses leaving the profession each year. The purpose of this project was to develop an understanding of the effect that nursing orientation has on job satisfaction, competence level, and the retention of NGRNs in a rural Kansas medical facility. A quantitative approach was utilized with a correlational research design. To develop an understanding of the perception of new graduate registered nurses an anonymous pre-validated online survey created by Shepard (2014) was distributed to all nursing staff through the facility email server. The demographic population was a convenience sample of 33 NGRNs. Descriptive statistics and Pearson’s rho analysis were completed to evaluate the correlation between survey questions. The findings of this study revealed that the majority of participants were satisfied overall with the received orientation program and planned to remain employed for at least 18-24 months from hire. Participants who felt their clinical skills improved during orientation were also more likely to be satisfied with the orientation program. Overall, the findings suggest that perceived satisfaction with the orientation program is related to increased skill competence, intention to remain employed, and job satisfaction
