Dallas Baptist University , formerly known as Dallas Baptist College, is a Christian liberal arts university located in Dallas, Texas. The main campus is located approximately 12 miles southwest of downtown Dallas overlooking Mountain Creek Lake. Founded in 1898 as Decatur Baptist College, Dallas Baptist University currently operates campuses in Dallas, Plano, and Hurst. Wikipedia.

Digital signatures are an important mechanism for ensuring data trustworthiness via source authenticity, integrity, and source nonrepudiation. However, their trustworthiness guarantee can be subverted in the real world by sophisticated attacks, which can obtain cryptographically legitimate digital signatures without actually compromising the private signing key. This problem cannot be adequately addressed by a purely cryptographic approach, by the revocation mechanism of Public Key Infrastructure (PKI) because it may take a long time to detect the compromise, or by using tamper-resistant hardware because the attacker does not need to compromise the hardware. This problem will become increasingly more important and evident because of stealthy malware (or Advanced Persistent Threats). In this paper, we propose a novel solution, dubbed Assured Digital Signing (ADS), to enhancing the data trustworthiness vouched by digital signatures. In order to minimize the modifications to the Trusted Computing Base (TCB), ADS simultaneously takes advantage of trusted computing and virtualization technologies. Specifically, ADS allows a signature verifier to examine not only a signature's cryptographic validity but also its system security validity that the private signing key and the signing function are secure, despite the powerful attack that the signing application program and the general-purpose Operating System (OS) kernel are malicious. The modular design of ADS makes it application-transparent (i.e., no need to modify the application source code in order to deploy it) and almost hypervisor-independent (i.e., it can be implemented with any Type I hypervisor). To demonstrate the feasibility of ADS, we report the implementation and analysis of an Xen-based ADS system. © 2012 IEEE.

Wind and solar energy are two forms of renewable energy that appear to be increasing in demand and these two forms have potential advantages in college campuses. Research was conducted to provide information to help universities and colleges evaluate the usefulness of wind and solar energy for their campuses. Interviews with officials at several colleges and universities were conducted to learn more about the factors that affect their decision. This is an abstract of a paper presented at the AWMA's 107th Annual Conference & Exhibition (Long Beach, CA 6/24-27/2014).

This study presents a metapopulation model for the sylvatic transmission of Trypanosoma cruzi, the etiological agent of Chagas' disease, across multiple geographical regions and multiple overlapping host-vector transmission cycles. Classical qualitative analysis of the model and several submodels focuses on the parasite's basic reproductive number, illustrating how vector migration across patches and multiple transmission routes to hosts (including vertical transmission) determine the infection's persistence in each cycle. Numerical results focus on trends in endemic [equilibrium] persistence levels as functions of vector migration rates, and highlight the significance of the different epidemiological characteristics of transmission in each of the three regions.

This research focuses on inservice science teachers’ conceptions of nature of science (NOS) before and after a two-week intensive summer professional development (PD). The PD combined traditional explicit NOS instruction, numerous interactive interventions that highlighted NOS aspects, along with documentary films that portrayed NOS in context of authentic scientific discovery. Reflective dialogue was used throughout the professional development to encourage constructivist learning. The PD addressed seven commonly held NOS tenets that are deemed significant to K-12 science teachers. Finally, qualitative methodologies were used to analyze the Views of Nature of Science Questionnaire (VNOS-D) and the associated interview data to explore subtleties within each NOS tenet and to gain a richer understanding of how the teachers’ NOS understanding differed before and after the PD. © 2015 by iSER, International Society of Educational Research.

Female offenders are showing a dramatic increase and presenting with several challenges to emotional stability. Current research literature notes the disadvantaged state of these women and psychological profiles reflecting depression, anxiety, trauma, shame, low self-worth, and substance abuse. The instillation of hope has been identified as a therapeutic factor and motivating energy that promotes goal development, reduction of negative emotions, and coping ability. This investigation assessed the impact of hope on female prisoners through the use of a psychoeducational group based on Christian spirituality. Data from the Herth Hope Index were analyzed using a series of t tests to measure group differences. Analysis of the data indicated positive change in the therapy group but did not support statistical significance for every factor analyzed, yet it does provide several implications for practice and future research. © The Author(s) 2010.
