Dutch Elm Disease Resistant Cultivars for Campus Environmental Sustainability

Dutch Elm Disease Resistant Cultivars for Campus Environmental Sustainability John Dryden, Dept. of Civil Engineering & Construction Management ($3,135.00) 100 Dutch Elm Disease (DED) Resistant elm cultivar seedlings were grown to sapling size, then planted around campus by student groups and GS Landscape Services, and serve as campus landmark trees during Arbor Day plantings. These saplings also serve as propagation ‘parents’, thus ensuring a steady future supply of DED resistant elm trees for GS. As there has been virtually no research into the performance of these cultivars in Georgia, the long-term performance of these cultivars was reported to the National Elm Trial as part of their continuing research

Digital Reconstruction Supporting Investigation of Mishaps

In support of investigations of mishaps like the crash of the space shuttle Columbia, a process based on digital reconstruction from recovered components has been developed. The process is expected to reduce the need for physical reconstruction from recovered parts, reduce the time and cost of determining the cause of a mishap, and provide information useful in redesigning to prevent future mishaps. The process involves utilization of pre-existing techniques, hardware, and software to capture sizes and shapes of recovered parts in sets of digital data. The data are manipulated to enable rendering of captured geometric information by use of computer-aided design (CAD) and viewing software. The digitization of a part and study of its spatial relationship with other parts is taken to one of three levels of successively greater detail, depending on its importance to the investigation. The process includes a trajectory-analysis subprocess in which information from the digital reconstruction is combined with locations of recovered parts to reduce the area that must be searched to find other specified parts that have not yet been recovered. The digital product of the process is compatible with preexisting CAD and solid-model-rendering software

Intimate Partner Violence and Women with Severe Mental Illnesses: Needs and Challenges from the Perspectives of Behavioral Health and Domestic Violence Service Providers

Women with severe mental illnesses face high rates of violence victimization, yet little is understood about the unique needs and challenges these women present to the domestic violence and behavioral health agencies that serve them. To help address this knowledge gap, focus groups were conducted with 28 staff members from local behavioral health and domestic violence service agencies. Results from this exploratory study suggest that women with severe mental illnesses who experience intimate partner violence face additional challenges that exacerbate behavioral health and domestic violence issues and put these women at greater risk for continued victimization. DV and behavioral health agency staff experience individual-, provider-, and system-level barriers to serving this high-risk, high-need population. Recommendations and implications for domestic violence and behavioral health providers are discussed

TESTING OF A 20-METER SOLAR SAIL SYSTEM

This paper describes the structural dynamic tests conducted in-vacuum on the Scalable Square Solar Sail (S(sup 4)) System 20-meter test article developed by ATK Space Systems as part of a ground demonstrator system development program funded by NASA's In-Space Propulsion program1-3. These tests were conducted for the purpose of validating analytical models that would be required by a flight test program to predict in space performance4. Specific tests included modal vibration tests on the solar sail system in a 1 Torr vacuum environment using various excitation locations and techniques including magnetic excitation at the sail quadrant corners, piezoelectric stack actuation at the mast roots, spreader bar excitation at the mast tips, and bi-morph piezoelectric patch actuation on the sail cords. The excitation methods were evaluated for their suitability to in-vacuum ground testing and their traceability to the development of on-orbit flight test techniques. The solar sail masts were also tested in ambient atmospheric conditions and these results are also discussed

Game Theoretical Interactions of Moving Agents

Game theory has been one of the most successful quantitative concepts to describe social interactions, their strategical aspects, and outcomes. Among the payoff matrix quantifying the result of a social interaction, the interaction conditions have been varied, such as the number of repeated interactions, the number of interaction partners, the possibility to punish defective behavior etc. While an extension to spatial interactions has been considered early on such as in the "game of life", recent studies have focussed on effects of the structure of social interaction networks. However, the possibility of individuals to move and, thereby, evade areas with a high level of defection, and to seek areas with a high level of cooperation, has not been fully explored so far. This contribution presents a model combining game theoretical interactions with success-driven motion in space, and studies the consequences that this may have for the degree of cooperation and the spatio-temporal dynamics in the population. It is demonstrated that the combination of game theoretical interactions with motion gives rise to many self-organized behavioral patterns on an aggregate level, which can explain a variety of empirically observed social behaviors

Integrating Assertive Community Treatment and Illness Management and Recovery for Consumers with Severe Mental Illness

This study examined the integration of two evidence-based practices for adults with severe mental illness: Assertive community treatment (ACT) and illness management and recovery (IMR) with peer specialists as IMR practitioners. Two of four ACT teams were randomly assigned to implement IMR. Over 2 years, the ACT–IMR teams achieved moderate fidelity to the IMR model, but low penetration rates: 47 (25.7%) consumers participated in any IMR sessions and 7 (3.8%) completed the program during the study period. Overall, there were no differences in consumer outcomes at the ACT team level; however, consumers exposed to IMR showed reduced hospital use over time

A parabolic approach to the control of opinion spreading

We analyze the problem of controlling to consensus a nonlinear system modeling opinion spreading. We derive explicit exponential estimates on the cost of approximately controlling these systems to consensus, as a function of the number of agents N and the control time-horizon T. Our strategy makes use of known results on the controllability of spatially discretized semilinear parabolic equations. Both systems can be linked through time-rescalin

A Scoping Review of Vicarious Trauma Interventions for Service Providers Working With People Who Have Experienced Traumatic Events

Health and human service providers who aid traumatized individuals frequently experience vicarious trauma (VT). Although VT plays a critical role in service providers’ mental health and well-being, as well as in the quality of their service provision, little information is available concerning the development and implementation of VT interventions for service providers. To advance the development of evidence in this area, we undertook a scoping review in which we reviewed existing interventions intended to address VT among service providers working with traumatized clients. Searches of electronic databases were conducted to identify studies published in peer-reviewed journals, with no date restrictions. Over 1,315 citations were reviewed, and a total of 27 studies were included in the final review. The findings show that VT interventions in the literature can be divided broadly into four categories: psychoeducation, mindfulness intervention, art and recreational programs, and alternative medicine therapy. The VT interventions reviewed generally showed promise in their key outcomes, including reductions in secondary trauma stress, compassion fatigue, burnout, and other mental health outcomes. However, the current body of research is lacking both in rigor and in specificity regarding the definition of VT. Furthermore, existing VT interventions are generally self-care based and tend to focus on general stress management rather than addressing the specific effects of VT. Therefore, we call for an increase in efforts to tailor VT interventions to different service settings and participant characteristics, as well as greater attention to developing primary VT interventions at the organizational level

Effects of a Game-Centered Health Promotion Program on Fall Risk, Health Knowledge, and Quality of Life in Community-Dwelling Older Adults

International Journal of Exercise Science 12(4): 1149-1160, 2019. Quality of life (QOL) is an important aspect of overall well-being in older adults and can be improved with increased physical activity. One in four older adults experiences a fall each year, making it necessary to focus public health interventions towards decreasing fall risk and improving QOL in older adults. The purpose of this study was to determine the effects of the health promotion program, Bingocize®, on QOL and fall risk in community-dwelling older adults (n = 36; mean age 73.63 ± 6.97). Participants were clustered and randomly assigned to (a) experimental (n = 19; participating in Bingocize® program, or (b) control (n = 17; only played normal bingo). Each group completed a 12-week intervention that consisted of two 45-60 minute sessions per week. There were no significant interactions for any of the variables, with the exception of positive affect (PA) (F (1,34) = 5.66, p = 0.02, = 0.15, power = 0.64) and handgrip strength (F (1,34) = 8.31, p = 0.007, = 0.196, power = 0.80). There was also a significant main effect for time for health knowledge. Participating in the Bingocize® health promotion program can produce a meaningful and detectable change in handgrip strength and PA in community-dwelling older adults
