Upon exiting high school, some African American students with disabilities experience difficulty accessing disability support services and appropriate accommodations. Many of these difficulties in access can be traced to high school transition planning as the source. To understand the underlying transitional barriers and sources of support, case studies were developed to examine the experiences of African American students with disabilities as they secured accommodations from disability services. The following themes resulting from the data were evident within the student portraits: (a) students believed deficit-ideologies undermined attempts at self-determination; (b) students emphasized the importance of adequate information prior to transition; and (c) students often refused to access services due to competing cultural identities. The theoretical frameworks of social and cultural capital were used to explore the transitional experiences of postsecondary African American students with disabilities. © Hammill Institute on Disabilities 2013.

Disability and Rehabilitation

The phenomenology of human embodiment can advance the practitioner's understanding of the lived human body and in particular, what it means to incorporate a prosthetic device into one's body. In order for a prosthesis to be incorporated into the lived body of the patient, the prosthesis must arguably be integrated into the body schema. This article uses the phenomenology of Maurice Merleau-Ponty and others to identify three of the necessary conditions of embodiment that determine the body schema: corporeal understanding, transparency and sensorimotor feedback. It then examines the structure of each of these conditions of embodiment and how they impact the lived body's incorporation of prostheses and other artifacts. Implications for Rehabilitation Phenomenology complements evidence-based research in the field of psychoprosthetics by a systematic study of the experience of what it is like for the prosthesis user to incorporate a prosthetic device into his or her body. The practictioner can use phenomenological insight to assess the qualitative progress of rehabilitation. In particular, significant progress towards the incorporation of the prosthetic device is achieved when the prothesis user experiences sensory and kinesthetic feedback as coming not from the interface between the residual limb and the prosthetic device, but from the combined residual limb-prosthetic device and its interface with the environment. An even more complete incorporation is experienced when the prosthesis becomes transparent, that is, when the prothesis user is focused on the perceptual object or behavioral goal rather than on the prosthetic device. © 2013 Informa UK, Ltd.

Considerable research has been done on the content-based multimedia delivery and access in distributed data repositories. As noted in the literature, there is always a trade-off between multimedia quality and access speed. In addition, the overall performance is greatly determined by the distribution of the multimedia data. In this article, an unsupervised multimedia semantic integration approach for a distributed infrastructure, the Distributed Semantic Indexing (DSI), is presented that addresses both the data quality and search performance. With the ability of summarizing content information and guiding data distribution, the proposed approach is distinguished by: (1) logic-based representation and concise abstraction of the semantic contents of multimedia data, which are further integrated to form a general overview of a multimedia data repository-content signature: (2) application of linguistic relationships to construct a hierarchical metadata based on the content signatures allowing imprecise queries; and (3) achieving the optimal performance in terms of search cost. The fundamental structure of the proposed model is presented. The proposed scheme has been simulated and the simulation results are analyzed and compared against several other approaches that have been advocated in the literature. © 2010 ACM. Source

Quantum Information Processing

We advance the previous studies of quantum walks on the line with two coins. Such four-state quantum walks driven by a three-direction shift operator may have nonzero limiting probabilities (localization), thereby distinguishing them from the quantum walks on the line in the basic scenario (i.e., driven by a single coin). In this work, asymptotic position distributions of the quantum walks are examined. We derive a weak limit for the quantum walks and explicit formulas for the limiting probability distribution, whose dependencies on the coin parameter and the initial state of quantum walks are presented. In particular, it is shown that the weak limit for the present quantum walks can be of the form in the basic scenario of quantum walks on the line, for certain initial states of the walk and certain values of the coin parameter. In the case where localization occurs, we show that the limiting probability decays exponentially in the absolute value of a walker's position, independent of the parity of time. © Springer Science+Business Media, LLC 2012.

The goal of this project is to stimulate interest in cybersecurity competitions through the development of a visualization and broadcast system targeted to enhancing learning and understanding among spectators. The system engages the spectator by presenting information pertinent to understanding the real-time details of the game in a usable and spirited manner. It accomplishes this through the combination of various techniques, including real-time network security visualization, live video and audio monitoring, animation, computer graphics and commentary. As a result, the project improves the educational value and excitement for the spectator and broaden interest in the field of cybersecurity.

The proposed tool captures computer and network activities for all the competing teams and present them in a user-friendly manner for the benefit of the spectator using state-of-the-art broadcasting, animation and commentary. Although visualization has been utilized at large-scale cyber defense competition, such as the Mid-Atlantic Collegiate Cyber Defense Competition, it is still used only in a limited way. Further, it does not target the spectator in a serious way and it is rarely used for small-scale cyber defense competitions, which is the main target of this project.

By improving the spectator experience, more students are attracted to collegiate cyber defense competitions and ultimately to cyber security related fields. The tool is also beneficial to competition participants, especially to student teams who could use the tool for network security visualization.
