Assess program: Interactive data management systems for airborne research

Two data systems were developed for use in airborne research. Both have distributed intelligence and are programmed for interactive support among computers and with human operators. The C-141 system (ADAMS) performs flight planning and telescope control functions in addition to its primary role of data acquisition; the CV-990 system (ADDAS) performs data management functions in support of many research experiments operating concurrently. Each system is arranged for maximum reliability in the first priority function, precision data acquisition

Latitudinal gradients of cosmic rays and the polarity reversal of the heliospheric magnetic field: A preliminary evaluation

Within the statistical limits imposed by the currently available data and the noise inherent in the determination of the latitudinal gradient, no evidence for the expected change in the latitudinal gradient from pre-1980 to post-1980 epochs can be found. In addition, the rigidity dependence of the gradient appears to be the same in the two epochs. Thus, no evidence is found for a sensitivity of the latitudinal gradient to the polarity of the largescale heliospheric magnetic field such as has been predicted by models incorporating particle drifts

Role of Lipid Peroxidation and Antioxidant Enzymes in Omega 3 Fatty Acids Induced Suppression of Breast Cancer Xenograft Growth in Mice

Background: Supplementing mice with high levels of dietary n-3 polyunsaturated fatty acids (PUFAs) increases the n-3 PUFAs in cell membranes, increases the susceptibility of the cells for lipid peroxidation (LPO) and decreases the growth rate of mammary and other tumors. However, the results of an earlier study indicated that a factor in addition to LPO was involved in the reduction in tumor growth in n-3 PUFAs fed mice. Athymic mice bearing MDA-MB-231 human breast carcinoma xenografts, were fed fish oil concentrate (FOC) or control diets, with and without supplemental Vitamin E (2000 IU /kg diet) and were sacrificed both before and after doxorubicin (DOX) treatment to evaluate factors involved in tumor growth suppression. Results: Prior to DOX, basal LPO in the tumor of 3% FOC fed mice was slightly higher than in the control fed mice and was decreased in mice consuming FOC with vitamin E. Vitamin E suppressed the DOX induced increase in LPO in the tumors of control mice, however, vitamin E was not sufficient to suppress a DOX induced increase in LPO in the tumors of FOC fed mice. The mean growth rate of tumors of FOC fed mice was significantly less than the mean growth rate of the tumors of control mice. Multiple regression analyses indicated that suppression of glutathione peroxidase (GPX) activity by FOC prior to DOX therapy was more important than increased LPO as an explanation of tumor growth suppression. Tumor induced cachexia was decreased in mice consuming FOC. Conclusions: It appears that the increased sensitivity to DOX was related to an FOC induced reduction in GPX activity. FOC reduced tumor induced cachexia

Combining Clay and Light Into Sculptural Forms

This problem concerns the feasibility of combining the elements of light and clay in a sculptural concept of design. The study has determined various procedures of combining the sculptural ceramic forms for the internal inplant of light sources. Specific questions posed were 1. Can the surface decoration be enhanced by external and internal lighting? 2. How does each surface quality, raku, and low-fire salt glaze differ with the interplay of light? 3. In what way may two surface qualities be applied to the same sculptural ceramic forms? 4. How does scale effect each of the pieces

The Perceived Relationship Among Personnel Readiness, Job Performance and Work Demands A Case for Physical Ability Testing

Human Systems Integration ReportThe military screening process entails meeting general physical and cognitive standards and then primarily matching candidates with a specialization based on cognitive test scores. Little consideration is given to the physical abilities required to perform tasks in that specialization. An online survey was used to explore the perceived relationship among personnel readiness, job performance and work demands for Boatswains Mates (BM) and Damage Controlmen (DC). This study explored four research questions to evaluate physical ability testing. Descriptive statistics showed that the participants had a wide range of experience levels. The results from the logistic model indicated no factors were significant of evaluation trait averages. The chi-square tests showed a difference in level of physical demands in three different modes of operations for both BMs and DCs. Both groups support the use of a physical ability testing in the selection process for job placement. Efforts to develop a physical ability test for use in the selection process, a physical remediation program for those who do not meet the standards, as well as a maintenance program to verify personnel still meet physical abilities are recommendations that should be considered for future research.http://archive.org/details/theperceivedrela1094517425Lieutenant, United States NavyApproved for public release; distribution is unlimited

The Hero\u27s Journey as Transformative Church Leadership

This dissertation explored the intersection of leadership of the church as an epic, visionary and transformational journey. Using the insights of Joseph Campbell’s work on cross-cultural mythology, A Hero with a Thousand Faces,presents what he calls, “The Hero’s Journey” or “Mono-myth” is a pattern of narrative that appears in dramas, storytelling, literature, ancient myths, movies, the world’s religions and psychological development. It is a map of the journeys taken by humans since the beginning and is found throughout the world as a blueprint of the growth and experience in life. Visionary leadership is about hope. Archetypes and mythology have heroes who are often seeking transformation. Visionary leadership creates a shared vision, purpose and strategy to accomplish the mission of the church. Visionary Leadership is an adventure to discover the personal and collective power of a church to navigate conflict, trauma, to make heroic transformative changes. Part One explored the state of the Church today as paradigm of mission and transformation. Part Two will examine the basic stages in the Hero’s Journey. Part Three will explore the Hero’s Journey as a metaphor of visionary leadership as it seeks so to create shared vision, purpose and strategy to accomplish the mission of the church. Because church leaders often deal with conflict in churches, we have devoted time to explore conflict transformation and the healing of trauma in making more effective pastors. Finally, we explored the Hero’s Journey as a model of Christian spirituality and its implications for church leadership

NASA Controller Acceptability Study 1(CAS-1) Experiment Description and Initial Observations

This paper describes the Controller Acceptability Study 1 (CAS-1) experiment that was conducted by NASA Langley Research Center personnel from January through March 2014 and presents partial CAS-1 results. CAS-1 employed 14 air traffic controller volunteers as research subjects to assess the viability of simulated future unmanned aircraft systems (UAS) operating alongside manned aircraft in moderate-density, moderate-complexity Class E airspace. These simulated UAS were equipped with a prototype pilot-in-the-loop (PITL) Detect and Avoid (DAA) system, specifically the Self-Separation (SS) function of such a system based on Stratway+ software to replace the see-and-avoid capabilities of manned aircraft pilots. A quantitative CAS-1 objective was to determine horizontal miss distance (HMD) values for SS encounters that were most acceptable to air traffic controllers, specifically HMD values that were assessed as neither unsafely small nor disruptively large. HMD values between 0.5 and 3.0 nautical miles (nmi) were assessed for a wide array of encounter geometries between UAS and manned aircraft. The paper includes brief introductory material about DAA systems and their SS functions, followed by descriptions of the CAS-1 simulation environment, prototype PITL SS capability, and experiment design, and concludes with presentation and discussion of partial CAS-1 data and results

Amplification of Earthquake Ground Motions in Washington, DC, and Implications for Hazard Assessments in Central and Eastern North America

The extent of damage in Washington, DC, from the 2011 MW 5.8 Mineral, VA, earthquake was surprising for an epicenter 130 km away; U.S. Geological Survey “Did-You-Feel-It” reports suggest that Atlantic Coastal Plain and other unconsolidated sediments amplified ground motions in the city. We measure this amplification relative to bedrock sites using earthquake signals recorded on a temporary seismometer array. The spectral ratios show strong amplification in the 0.7 to 4 Hz frequency range for sites on sediments. This range overlaps with resonant frequencies of buildings in the city as inferred from their heights, suggesting amplification at frequencies to which many buildings are vulnerable to damage. Our results emphasize that local amplification can raise moderate ground motions to damaging levels in stable continental regions, where low attenuation extends shaking levels over wide areas and unconsolidated deposits on crystalline metamorphic or igneous bedrock can result in strong contrasts in near-surface material properties

Archaeological Investigations within San Pedro Springs Park (41BX19), San Antonio, Bexar County, Texas

The University of Texas at San Antonio Center for Archaeological Research (UTSA-CAR) contracted with Adams Environmental, Inc. to provide archaeological services to Capital Improvement Management (CIMS) of the City of San Antonio (COSA) related to the archaeological investigation of selected areas of San Pedro Springs Park in San Antonio, Bexar County, Texas. The CAR conducted archaeological testing at this National Register Site, 41BX19, from early December 2013 to mid-January of 2014. The goals of archaeological investigations were to identify and investigate any proto-historic and historic archaeological deposits associated with Colonial Period occupants of the area, including evidence of the first acequia and associated dam, and the location of the first presidio and villa. In addition, CAR was tasked with the investigation of any prehistoric cultural deposits encountered. This project was performed by staff archaeologists from the CAR. It was conducted under Texas Antiquities Permit No. 6727, with Dr. Steve Tomka serving as Principal Investigator (PI), and Kristi Nichols and Stephen Smith serving as Project Archaeologists. Dr. Tomka departed from UTSA shortly after the completion of fieldwork. At that time, Dr. Raymond Mauldin of CAR assumed PI responsibilities for the project. One hundred and eleven shovel tests, eleven 1-x-1 m test units, two 50-x-50 cm units, two backhoe trenches, and several auger holes were excavated during this effort. Minimal artifactual evidence of colonial occupants was noted during the archaeological investigations. Several Native American bone tempered sherds that could reflect either Late Prehistoric Leon Plain or Goliad ware were recovered. However, no Spanish Majolicas or lead glazed wares were uncovered, and no gunflints were identified in the lithic assemblage. Due to various utility lines and other obstructions, backhoe trenches to search for the acequia and associated dam could not be excavated. It is likely that areas proposed for investigation of the acequia and associated dam have been disturbed by aforementioned utility lines as well as earlier construction within the park. No evidence of the specific location of the first presidio or villa was located. Shovel testing and test units revealed the presence of historic and prehistoric use of the park, though mixing of historic and prehistoric material, as well as other disturbances (e.g., rodents), was common in the deposits. However, there was an increase in prehistoric material with depth as revealed in shovel testing results. Shovel testing located Feature 1, a burned rock feature that possibly was associated with a sheet midden, as well as several areas with high densities of prehistoric materials. Test excavations, based on these shovel tests, suggest that Feature 1 is a discrete feature that lies below a widespread, low-density distribution of burned rock. Shovel testing also identified a high-density cluster of lithic, bone, and burned rock. The excavation of a 1-x-1 m test unit (TU 4) in this area produced over 4,000 pieces of debitage, with over 50% of this total coming from three levels. Burned rock, a variety of tools, faunal material, and charcoal were present throughout these levels. Temporal placement of deposits relied on artifact typologies (e.g., ceramic types, lithic projectile points, lithic tool types) as well as two charcoal and four bone collagen radiocarbon dates. Artifact typologies suggest occupation as early as the Early Archaic as reflected by a possible Guadalupe tool. A series of Late Archaic Points (Castroville, Frio, Marcos, and Montell) and Late Prehistoric point forms (Edwards, Perdiz, and Scallorn) are present from several areas. In addition, a possible Middle Archaic La Jita point was recovered. The bone tempered Native American wares could date as early as AD 1250, though they could also reflect proto-historic or colonial age materials. Other ceramics primarily suggest a mid-nineteenth- to midtwentieth-century occupation. Using the midpoints of the 1-sigma distribution, calibrated radiocarbon dates show use of San Pedro Park from as early as 100 AD (CAR 345; 1905 +/- 22 Radiocarbon Years Before Present [RCYBP]) to as recently as the early twentieth century. The more recent end of that range is a function of two late dates from two different areas of the park. The first of these is on a bison bone (CAR 344) that returned a date of 158 +/- 23 RCYBP. The second is on a bone consistent with a bison-sized animal (CAR 346) that produced a date of 155 +/- 23 RCYBP. The corrected, calibrated dates for these two samples range from AD 1670 to the early 1940s using the 1-sigma spread. The wide range of these dates is related to the flat calibration curve late in time. However, the most probable date range (ca. 36% probability) for these two dates is between AD 1729 and 1779, with a roughly 48% probability that they date prior to AD 1779. Limited testing suggests that, with a few specific exceptions, the upper 30-40 cm of San Pedro Park is extensively disturbed. However, though some disturbances are present, at least three areas have materials in what appears to be good context. These include material dating to the Late Archaic, Late Prehistoric, and possibly the Proto-historic or Colonial Period. Based on historic maps, previous work, and the current investigation, CAR proposes a series of management areas for San Pedro Park. If work in these management areas follows these suggestions for various limits on subsurface impacts, CAR recommends that. renovation activities within the park be allowed to proceed. The Texas Historical Commission (THC), in a letter dated February 4, 2015, agreed with these recommendations. Finally, CAR provides several recommendations for public education facilities within the park. In accordance with the THC Permit specifications and the Scope of Work for this project, all field notes, analytical notes, photographs, and other project related documents, along with a copy of the final report, will be curated at the CAR. After quantification and completion of analysis, and in consultation with THC and the COSA Office of Historic Preservation, artifacts possessing little scientific value were discarded pursuant to Chapter 26.27(g)(2) of the Antiquities Code of Texas. Artifact classes discarded specific to this project included samples of burned rock and snail shell, all unidentifiable metal, soil samples, and recent (post-1950) material
