ASEAN SECURITY COOPERATION: NTS AND WMD/CBRN
This thesis examines the developing response of the Association of Southeast Asian Nations (ASEAN) toward weapons of mass destruction (WMD) and the chemical, biological, radiological, and nuclear (CBRN) range of threats as a case study of its approach to non-traditional security issues. Over the past two decades, ASEAN-led WMD/CBRN cooperation largely emphasized rhetoric, dialogue, treaties, and confidence-building measures, which were especially notable in the ASEAN Regional Forum (ARF). Although ASEAN leaders previously expressed their support toward international cooperation, they initially limited their activities to diplomacy, which frustrated their extra-regional partners. However, ASEAN’s activities within the last few years indicate that it has become more inclined toward developing the capabilities necessary for disrupting threat WMD proliferation efforts and responding to potential WMD/CBRN incidents. In 2018, defense leaders and practitioners of the ASEAN Defense Ministers Meeting established the Network of ASEAN Chemical, Biological, and Radiological Defense Experts, or the “ASEAN CBR Network.” The following year, the ARF heads of state planned to conduct a tabletop exercise to address WMD disarmament, non-proliferation, and capability generation. This thesis reveals that ASEAN’s approach to region-specific WMD/CBRN security challenges is changing, although this shift has been mostly from diplomacy to consultation, education, and limited exercise planning.Captain, United States ArmyApproved for public release.

Impact of School Calendar on Academic Performance: A Comparative Study of the Year-Round and Traditional Calendars
Educational provisions enacted at the national level impact states by requiring a priority on improving the academic performance of students. Leaders in educational settings strive to implement changes that will aid in closing achievement gaps and increase academic achievement. The goal of this quantitative study was to determine if differences exist on fifth grade students’ performance on reading and mathematics assessments between schools on full-year calendars and schools on traditional 9-month calendars for years 2016-2017, 2017-2018, and 2018-2019. Although statistically significant differences were not found, results inform decision-making pertinent to time allocated for student learning. Results can be considered by district and campus administrators to support and encourage initiatives which focus on designated instructional time to target students’ academic needs
Spring Hydrology of Colorado Bend State Park, Central Texas
Karst development in Ellenburger carbonates near Colorado Bend State Park in central Texas exhibits complex polygenetic origins, with porosity development dominated by an early hypogene phase that has subsequently been overprinted to varying degrees by epigene processes. Quarterly physicochemical and continuous thermal monitoring analyses of eight springs in the study area indicate that modern groundwater flow paths are highly variable. Springs exhibit patterns that range from shallow, distributed recharge into diffuse-flow dominated systems, to focused recharge into well-connected conduit systems, to deep-circulation systems that equilibrate with bedrock. All springs, except Sulphur Spring, exhibit physicochemical characteristics indicative of proximal epigenic groundwater flow through Ellenburger carbonates, while Sulphur Spring shows elevated temperature and dissolved-ion concentrations indicative of longer groundwater flow paths through deeper strata. The polygenetic nature of karst development in the Colorado Bend State Park has created an enhanced porosity structure which forms a complex modern groundwater flow network
Preliminary Testing of a Pressurized Space Suit and Candidate Fabrics Under Simulated Mars Dust Storm and Dust Devil Conditions
In August 2009 YAP Films (Toronto) received permission from all entities involved to create a documentary film illustrating what it might be like to be on the surface of Mars in a space suit during a dust storm or in a dust devil. The science consultants on this project utilized this opportunity to collect data which could be helpful to assess the durability of current space suit construction to the Martian environment. The NDX?1 prototype planetary space suit developed at the University of North Dakota was used in this study. The suit features a hard upper torso garment, and a soft lower torso and boots assembly. On top of that, a nylon-cotton outer layer is used to protect the suit from dust. Unmanned tests were carried out in the Martian Surface Wind Tunnel (MARSWIT) at the NASA Ames Research Center, with the suit pressurized to 10 kPa gauge. These tests blasted the space suit upper torso and helmet, and a collection of nine candidate outer layer fabrics, with wind-borne simulant for five different 10 minute tests under both terrestrial and Martian surface pressures. The infiltration of the dust through the outer fabric of the space suit was photographically documented. The nine fabric samples were analyzed under light and electron microscopes for abrasion damage. Manned tests were carried out at Showbiz Studios (Van Nuys, CA) with the pressure maintained at 20?2 kPa gauge. A large fan-created vortex lifted Martian dust simulant (Fullers Earth or JSC Mars?1) off of the floor, and one of the authors (Lee) wearing the NDX?1 space suit walked through it to judge both subjectively and objectively how the suit performed under these conditions. Both the procedures to scale the tests to Martian conditions and the results of the infiltration and abrasion studies will be discussed
Increasing compliance with wearing a medical device in children with autism
Health professionals often recommend the use of medical devices to assess the health, monitor
the well-being, or improve the quality of life of their patients. Children with autism may present
challenges in these situations as their sensory peculiarities may increase refusals to wear such
devices. To address this issue, we systematically replicated prior research by examining the
effects of differential reinforcement of other behavior (DRO) to increase compliance with
wearing a heart rate monitor in 2 children with autism. The intervention increased compliance to
100% for both participants when an edible reinforcer was delivered every 90 s. The results
indicate that DRO does not require the implementation of extinction to increase compliance with
wearing a medical device. More research is needed to examine whether the reinforcement
schedule can be further thinned
Towards a framework for critical citizenship education
Increasingly countries around the world are promoting forms of "critical" citizenship in the planned curricula of schools. However, the intended meaning behind this term varies markedly and can range from a set of creative and technical skills under the label "critical thinking" to a desire to encourage engagement, action and political emancipation, often labelled "critical pedagogy". This paper distinguishes these manifestations of the "critical" and, based on an analysis of the prevailing models of critical pedagogy and citizenship education, develops a conceptual framework for analysing and comparing the nature of critical citizenship
Maladaptive behaviors are linked with inefficient sleep in individuals with developmental disabilities
The purpose of the current study was to assess the relations between nightly sleep patterns and the frequency of daily maladaptive behavior. Antecedent and consequential relations between sleep patterns and behavior were evaluated with time series analysis. Sleep efficiency and maladaptive behavior were determined for 20 female residents of an institutional care facility for adults with developmental disabilities. Daily maladaptive behavioral data and nightly sleep/awake logs were collected for 4Â months for each participant. Efficient sleep patterns were significantly associated with lower frequencies of maladaptive behaviors. All lagged cross-correlations 8Â days before and 8Â days after an evening of sleep were significant. These findings suggested that inefficient sleep was associated with increased maladaptive behaviors and that the lagged associations reflected a chronic but not an acute linkage between sleep and behavior
