Review of \u3ci\u3eChief Red Fox is Dead: A History of Native Americans Since 1945\u3c/i\u3e By James J. Rawls

In the second chapter of God Is Red: A Native View of Religion(1973), Vine Deloria Jr. notes the dominant culture\u27s persistent consumption of either villianized or romanticized images of Native Americans present in disputed histories such as The Memoirs of Chief Red Fox (1971). In Chief Red Fox Is Dead: A History of Native Americans Since 1945, James J. Rawls writes for primarily non-Indian readers who accept images such as Chief Red Fox as authentic representations of Native America and, therefore, who may have some difficulty accepting Indians as contemporary beings. Rawls intends to reveal the falsity of what scholars, following Deloria, have called white man\u27s Indians and pretend Indians by presenting the history of twentieth-century Native America. Rawls begins his first chapter with a synopsis of an Apache attack on white settlers in John Ford\u27s Stagecoach (1939). Marauding Apaches and the additional popular stereotypes of Native Americans Rawls lists contrast with the real Native American participation in World War II at home and overseas. In the following chapters, Rawls reviews the history of removal, reservations, allotment, and the Collier era at the BIA to contextualize termination, relocation, and the subsequent drive towards self-determination. This exploration of federal law and pan-Indian attempts to be involved in the legal process benefits from the inclusion of Native American voices on both sides of the political debates. In his discussion, Rawls considers national news-making events, such as the occupations of Alcatraz, the BIA, and Wounded Knee, and less spectacular but equally important events such as the return of Blue Lake to the Taos Pueblo in 1970. The up-to-date analysis includes assessments of Reagan\u27s disastrous administration and the Bush and Clinton presidencies. In the final chapters, Rawls examines poverty, health, and education on reservations, and pan-Indian activism in the 1960s and 1970s. He explains battles over energy resources, economic autonomy, and repatriation, and surveys contemporary Native American religion. While the section on the Native American fine arts movement is thorough and informative, Rawls rushes through a list of authors in the chapter Native American Voices. Despite the hasty treatment, a contrast emerges between N. Scott Momaday\u27s Pulitzer Prize for House Made of Dawn (1968) and the continued existence in 1990s popular culture of the racist subhuman and romanticized superhuman Native American. The persistence of these stereotypes, which Rawls attempts to invalidate in his study, is a telling indication of white culture\u27s resistance to Native American self-definition

Limits of Nematoscelis megalops in the northwestern Atlantic in relation to Gulf Stream cold core rings. II, Physiological and biochemical effects of expatriation

Originally published in the Journal of Marine Research, v. 36, 1, 1978, pp. 143-159Nematoscelis megalops, a cold water euphausiid commonly found in Northwestern Atlantic Slope Water, is frequently transported in the cores of Gulf Stream cyclonic rings into the Sargasso Sea. The inner core made of cold Slope Water gradually assumes physical and biological characteristics of the surrounding Sargasso Sea. These changes gradually lead to a localized extinction of this species in the core of the ring. Samples of N. megalops taken from the same ring at 6 and 9 months after its formation show a weakened physiological and biochemical condition. Deterioration of ring individuals is evidenced by an increase in body water content and a reduction in total body lipid, carbon, respiration rates, and nitrogen relative to Slope Water individuals. By 6 months it appears that ring N. megalops must supplement food intake by metabolizing some of their body protein and by 9 months they appear to use lipids as well. A shipboard starvation experiment involving 40 Slope Water individuals showed that physiological and biochemical states similar to those found in individuals from the 9 months old ring could be duplicated in 4 days of complete starvation.Prepared for the Office of Naval Research under Contracts N00014-66-C-0241; NR 083-004 and N00014-?4-C-0262; NR 083-004 and for the National Science Foundation under Grant DES ?4-02?83 A01

Tracking Cyber Adversaries with Adaptive Indicators of Compromise

A forensics investigation after a breach often uncovers network and host indicators of compromise (IOCs) that can be deployed to sensors to allow early detection of the adversary in the future. Over time, the adversary will change tactics, techniques, and procedures (TTPs), which will also change the data generated. If the IOCs are not kept up-to-date with the adversary's new TTPs, the adversary will no longer be detected once all of the IOCs become invalid. Tracking the Known (TTK) is the problem of keeping IOCs, in this case regular expressions (regexes), up-to-date with a dynamic adversary. Our framework solves the TTK problem in an automated, cyclic fashion to bracket a previously discovered adversary. This tracking is accomplished through a data-driven approach of self-adapting a given model based on its own detection capabilities. In our initial experiments, we found that the true positive rate (TPR) of the adaptive solution degrades much less significantly over time than the naive solution, suggesting that self-updating the model allows the continued detection of positives (i.e., adversaries). The cost for this performance is in the false positive rate (FPR), which increases over time for the adaptive solution, but remains constant for the naive solution. However, the difference in overall detection performance, as measured by the area under the curve (AUC), between the two methods is negligible. This result suggests that self-updating the model over time should be done in practice to continue to detect known, evolving adversaries.Comment: This was presented at the 4th Annual Conf. on Computational Science & Computational Intelligence (CSCI'17) held Dec 14-16, 2017 in Las Vegas, Nevada, US

Recovery Act: Advanced Direct Methanol Fuel Cell for Mobile Computing

ABSTRACT Project Title: Recovery Act: Advanced Direct Methanol Fuel Cell for Mobile Computing PROJECT OBJECTIVE The objective of the project was to advance portable fuel cell system technology towards the commercial targets of power density, energy density and lifetime. These targets were laid out in the DOE’s R&D roadmap to develop an advanced direct methanol fuel cell power supply that meets commercial entry requirements. Such a power supply will enable mobile computers to operate non-stop, unplugged from the wall power outlet, by using the high energy density of methanol fuel contained in a replaceable fuel cartridge. Specifically this project focused on balance-of-plant component integration and miniaturization, as well as extensive component, subassembly and integrated system durability and validation testing. This design has resulted in a pre-production power supply design and a prototype that meet the rigorous demands of consumer electronic applications. PROJECT TASKS The proposed work plan was designed to meet the project objectives, which corresponded directly with the objectives outlined in the Funding Opportunity Announcement: To engineer the fuel cell balance-of-plant and packaging to meet the needs of consumer electronic systems, specifically at power levels required for mobile computing. UNF used existing balance-of-plant component technologies developed under its current US Army CERDEC project, as well as a previous DOE project completed by PolyFuel, to further refine them to both miniaturize and integrate their functionality to increase the system power density and energy density. Benefits of UNF’s novel passive water recycling MEA (membrane electrode assembly) and the simplified system architecture it enabled formed the foundation of the design approach. The package design was hardened to address orientation independence, shock, vibration, and environmental requirements. Fuel cartridge and fuel subsystems were improved to ensure effective fuel containment. PROJECT OVERVIEW The University of North Florida (UNF), with project partner the University of Florida, recently completed the Department of Energy (DOE) project entitled “Advanced Direct Methanol Fuel Cell for Mobile Computing”. The primary objective of the project was to advance portable fuel cell system technology towards the commercial targets as laid out in the DOE R&D roadmap by developing a 20-watt, direct methanol fuel cell (DMFC), portable power supply based on the UNF innovative “passive water recovery” MEA. Extensive component, sub-system, and system development and testing was undertaken to meet the rigorous demands of the consumer electronic application. Numerous brassboard (nonpackaged) systems were developed to optimize the integration process and facilitating control algorithm development. The culmination of the development effort was a fully-integrated, DMFC, power supply (referred to as DP4). The project goals were 40 W/kg for specific power, 55 W/l for power density, and 575 Whr/l for energy density. It should be noted that the specific power and power density were for the power section only, and did not include the hybrid battery. The energy density is based on three, 200 ml, fuel cartridges, and also did not include the hybrid battery. The results show that the DP4 system configured without the methanol concentration sensor exceeded all performance goals, achieving 41.5 W/kg for specific power, 55.3 W/l for power density, and 623 Whr/l for energy density. During the project, the DOE revised its technical targets, and the definition of many of these targets, for the portable power application. With this revision, specific power, power density, specific energy (Whr/kg), and energy density are based on the total system, including fuel tank, fuel, and hybridization battery. Fuel capacity is not defined, but the same value is required for all calculations. Test data showed that the DP4 exceeded all 2011 Technical Status values; for example, the DP4 energy density was 373 Whr/l versus the DOE 2011 status of 200 Whr/l. For the DOE 2013 Technical Goals, the operation time was increased from 10 hours to 14.3 hours. Under these conditions, the DP4 closely approached or surpassed the technical targets; for example, the DP4 achieved 468 Whr/l versus the goal of 500 Whr/l. Thus, UNF has successfully met the project goals. A fully-operational, 20-watt DMFC power supply was developed based on the UNF passive water recovery MEA. The power supply meets the project performance goals and advances portable power technology towards the commercialization targets set by the DOE
