Making On-Demand Routing Efficient with Route-Request Aggregation
In theory, on-demand routing is very attractive for mobile ad hoc networks
(MANET), because it induces signaling only for those destinations for which
there is data traffic. However, in practice, the signaling overhead of existing
on-demand routing protocols becomes excessive as the rate of topology changes
increases due to mobility or other causes. We introduce the first on-demand
routing approach that eliminates the main limitation of on-demand routing by
aggregating route requests (RREQ) for the same destinations. The approach can
be applied to any existing on-demand routing protocol, and we introduce the
Ad-hoc Demand-Aggregated Routing with Adaptation (ADARA) as an example of how
RREQ aggregation can be used. ADARA is compared to AODV and OLSR using
discrete-event simulations, and the results show that aggregating RREQs can
make on-demand routing more efficient than existing proactive or on-demand
routing protocols

Analyzing the validity of self-reports of emotional responding using an electronic device
The assessment of internal behaviors such as thoughts, feelings, or physiological symptoms not seen by the naked eye are often assessed with indirect measures such as self-reports and questionnaires given the lack of accessibility and observations by outside observers. The self-management of human behaviors, including internal events, carries socially valid implications for an individual’s quality of life, including children and individuals with neurological, developmental, and intellectual disabilities. This study aimed to address the following question: are there valid measurement procedures (e.g., collecting data on physiological responses) to analyze the correspondence between self-reports of emotional states and observable and measurable overt behaviors? To address the limitations in measurement validity of private, covert behaviors, the primary researcher of this study conducted a correspondence check of these three measurements with two participants with autism spectrum disorder in the following manner: collected heart rate data of the participants via a wearable device (Fitbit® Charge 5), conducted direct observation and data recording of overt behaviors, and collected data on the participants’ self-report of their emotional or physiological state via a 5-point rating scale across several time periods per session. Results of the study showed a strong positive correlation between observer and participant ratings from the 5-point rating scales; however, physical activity of the participants seemed to consistently mask true heart rate readings of the emotional responses. More research can be done on the correspondence of these three variables and their implications for guiding self-management programs of private events
From acceptance to graduation: Supporting students in recovery throughout their college experience
Students entering universities while in recovery from addiction face unique challenges, such as transitioning from a high school to a university, adapting to life after treatment, and/or transferring from a junior college or different university setting. Students in recovery also encounter challenges upon graduation including addressing gaps of employment on resumes, interviewing skills, and general professionalism. Cougars in Recovery offers support to students in recovery at the University of Houston in their academic journey through the use of programs including Source of Strength, offering peer to peer mentorship within the community and Career Ready Coogs, providing support for students approaching graduation with professional development resources. Longitudinal data is still being collected to demonstrate the influence of Source of Strength on Cougars in Recovery member retention and how Career Ready Coogs influences professional growth and preparation for graduation. Peer mentorship and professional development programs can help students in recovery navigate the challenges of the collegiate experience and entering the professional world
Digital Guided Writing Instruction: A Resource Collection for Distance Learning
This project created a digital resource collection that provides virtually guided writing instruction to students in distance learning environments. The collection targets third-grade students and teachers and provides four lessons that instruct users on narrative, opinion, summary, and informational writing. The collection was created to address the lack of guided writing instruction that is available in a purely virtual format. The need for this kind of a curriculum arose as a result of school closures during the COVID-19 pandemic. During this time, districts around the world turned to distance learning as a temporary alternative to in-person instruction. With this unprecedented shift came a number of challenges as educators, districts, students, and parents were left with little to no time to adapt to these changes. As a consequence, traditional school hours were no longer accessible to all families due to their varied work schedules and home lives during the pandemic. This made live virtual instruction an inequitable solution for replacing in-person teaching. To address this constraint and the need for a more equitable form of guided writing instruction, a literature review was conducted on effective writing practices, learning with technology, and student motivation. These findings inspired the idea of creating a self-accessed, self-directed, self-paced, and predictive digital resource collection that meets the writing needs of students who are active members of a distance learning community. Since not enough research on distance learning currently exists to measure the effectiveness of this collection, future researchers can further the value of this project by evaluating it under the lens of future findings on remote learning
A Retrospective Study of Teen Pregnancy in West Virginia from 2003 -2008: A Descriptive Analysis
In 2006, West Virginia surpassed the national average birth rate for teens ages 15 to 19 years old. Through the use of the state wide Birth Score data, this article presents a retrospective examination of 8,094 teens who gave birth in West Virginia during the years of 2003-2008. Descriptive data on health issues such as prenatal care, infant birth weight and mortality, as well as demographic characteristics, such a racial background and Medicaid status are presented. Implications of these health issues are discussed along with special considerations for health providers who work within the Appalachian region
