Hana Cervinkova, Playing Soldiers in Bohemia: An Ethnography of NATO Membership. Prague Studies in Sociocultural Anthropology 4, 2006, 161 pages.
Marybeth Peterson Ulrich
Journal of Power Institutions in Post-Soviet Societies , 2007,
Abstract: Hana Cervinkova’s ethnographic portrait of the Czech military in its “post-socialist” moment is a fascinating contribution to the literature on post-communist transitions. Not merely concerned with the provision of several anthropological descriptions of disappearing cultures, such as the obsolescent enlisted ranks and Air Force technicians expert in the mechanics of moth-balled Soviet aircraft, Cervinkova is determined to link the military’s post-socialist story to the Czech state’s own fort...
Engineering education in the wake of hurricane Katrina
Marybeth Lima
Journal of Biological Engineering , 2007, DOI: 10.1186/1754-1611-1-6
Abstract: Hurricane Katrina struck the gulf coast on August 29, 2005. This natural disaster catastrophically affected the U.S. gulf states and negatively impacted the entire country. My place of residence, Baton Rouge, Louisiana, survived hurricane Katrina with serious but non-catastrophic damage because the edge of the 40 mile wide eye of the storm passed 90 miles to the east of the city.I experienced many events analytically and from an engineering perspective, for example, the doubling of our city population, traffic gridlock, loss of communication (two days), loss of power (three days), and a gas shortage (none for five days, shortage for five weeks). Volunteering in the aftermath of Katrina provided many more experiences that were primarily emotional. I volunteered at the University of New Orleans satellite office that was established on the Louisiana State University (LSU) campus just after the hurricane. Employees were supposed to call in with contact information and their evacuation location; about half the calls I fielded were from relatives of the employees who were trying to ensure that their loved ones were okay. On the rare occasions that a loved one's relative had already contacted us, I could inform the caller that the person was safe, but I wasn't allowed to provide the person's phone number for liability reasons.School classrooms and boy and girl scout troops from all over the country sent school supplies for displaced children; while unpacking these supplies, our public school distribution team read heartfelt words of hope and kindness that frequently brought us to tears.The LSU AgCenter livestock barn, the Parker Coliseum, was turned into a holding area for pets evacuated from the storm. Of all my experiences, the wall of animals seeking people was the most poignant. While staring at approximately 150 Polaroid pictures of animals replete with their names and tags and the words OWNER MISSING printed on every photograph, I realized that I never would have con
Contextos comunitários favoráveis ao bem-estar
Análise Psicológica , 2007,
Abstract: this chapter identifies "context minimization error" as the tendency to ignore the impact of enduring neighbourhood and community contexts on human behaviour. the error has adverse consequences for understanding psychological processes and efforts at social change. the chapter describes a series of theoretical models of how neighbourhoods and community settings are associated with various aspects of human welfare and reviews evidence of associations of context with health, psychological distress, risk behaviours, psychological attitudes, and child development. it suggests that many psychological processes may play out differently in different contexts and that contextual factors interact with socio-cultural characteristics of individuals in predicting outcomes. people, in turn, can shape community contexts. a more sophisticated understanding of the effects of contexts depends on more sophisticated approaches to assessing them.
The Challenge of Copyright in the Digital Age
Marybeth Peters
La Propiedad Inmaterial , 2006,
Abstract: The author explains how the revolution in the way new technology can reproduce, disseminate, and store digital information, including copyrighted works, is truly a double-edged sword for authors and right-holders. The challenge of copyright in the digital age is to preserve the author’s and right-holder’s incentive to create new works and use new technologies to distribute them to users and consumers in the face of a huge competitive threat from the illicit use of technology by infringers. Finally, the author warns about the debate that new technologies often prompt about whether the set of exclusive rights granted to authors and right-holders should be modified, either with new or broadened rights or new or broadened exemptions, to continue to serve the purpose of copyright.
Acquiring High to Ultra-High Resolution Geological Records of Past Climate Change by Scientific Drilling
Juergen Thurow,Larry C. Peterson,Ulrich Harms,David A. Hodell
Scientific Drilling , 2009, DOI: 10.2204/iodp.sd.8.08.2009
Abstract: Scientific drilling on land and sea has played a key role in advancing our knowledge of climate change. It has helped to demonstrate the effects of orbital variations on climate, revealed evidence for extreme warm events in the past and for the timing of Antarctic ice growth, and provided insights into the hydrologic balance of lake systems around the world. Now, with attention increasingly focused on the likely manifestation of future climate change, the challenge to understand past climates at societally relevant, high-resolution timescales has become ever more critical. Sediments and other archives that preserve climate information ontimescales approaching those of instrumental records have much to offer to our understanding of how the climate system works (Fig. 1). These records, ideally with a sub-annual to centennial resolution, provide a unique opportunity to evaluate the global operation of the ocean-continent-atmosphere system on human timescales and to appraise the relative importance of each part of the system.
Pilot Scale Mill Characterization and Evaluation of Rice Bran Oil Concentration of Jazzman Rice  [PDF]
Rebecca Schramm, Grant Gonzalez, Nicole Walker, Marybeth Lima
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.612189
Abstract: The demand for aromatic rice has increased in the United States during the last two decades. Jazzman, the first US-bred jasmine-type rice variety, was released by the Louisiana State University (LSU) AgCenter Rice Research Station in 2008 to compete for a market share of jasmine-type rice. Jazzman, a long grain aromatic rice variety, was developed from a cross between Ahrent and an unreleased aromatic Chinese rice line 96a-8. In pre-release field tests and laboratory scale evaluation, Jazzman rice yield and milling quality compared favorably with two high-yielding and good-milling non-aromatic long grain varieties, Cypress and Cheniere. Pilot scale evaluation of Jazzman for milling quality supported laboratory scale evaluation while providing additional data for milling optimization. Pilot scale milling uses larger rice samples than laboratory scale testing and employs a continuous process instead of the batch process used at laboratory scale. As a result, pilot scale milling offers more comprehensive information regarding the milling yield and quality of rice varieties as they are considered for industrial scale release. Another consideration for new rice varieties involves their potential for value-added processing, in which waste streams during processing can be used to create valuable products. The oil from rice bran is one such product. The objective of this study was to use pilot scale milling to determine the potential of Jazzman for industrial scale release, including its potential for value-added processing. Results showed that bran was easily removed during milling; the head rice recovery ranged from 66% to 74% as a function of milling flow rate. Water polishing had little effect on head rice recovery, but improved the final degree of milling (DOM) to a commercially acceptable level of 87 - 90. Additionally, rice bran oil concentration decreased as pilot scale flow rate increased, indicating that oil was concentrated in the outer bran layer of Jazzman. Pilot scale milling shows that Jazzman is a high-yielding and good-milling aromatic long grain rice variety.
Mathematical Rotordynamic Model Regarding Excitation Due to Elliptical Shaft Journals in Electrical Motors Considering the Gyroscopic Effect  [PDF]
Ulrich Werner
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.48A009

The paper presents a mathematical rotordynamic model regarding excitation due to elliptical shaft journals in sleeve bearings of electrical motors also considering the gyroscopic effect. For this kind of excitation, a mathematical rotordynamic model was developed considering the influence of the oil film stiffness and damping of the sleeve bearings, the stiffness of the end-shields and bearing housings, the stiffness of the rotor, the electromagnetic stiffness in the air gap of the electrical motor and the mass moment of inertia of the rotor and therefore also considering the gyroscopic effect. The solution of the linear differential equation system leads to the mathematical description of the absolute orbits of the shaft centre, the shaft journals and the bearing housings and to the relative orbits between the shaft journals and the bearing housings. Additionally, the bearing housing velocities can also be derived with this mathematical rotordynamic model.

Complications of physician misdiagnosis/treatment of rheumatic fever in the United States  [PDF]
Diana C. Peterson
Advances in Bioscience and Biotechnology (ABB) , 2013, DOI: 10.4236/abb.2013.41A021

Rheumatic fever is an auto-immune disease caused by exposure to Streptococcus pyogenes. Over the last 50 years, reports of rheumatic fever within the United States have diminished. The decrease was attributed to the advent of penicillin in the treatment of streptococcus infections. We propose that current diagnostic and treatment methodologies may adversely increase the morbidity rate of rheumatic fever within the United States. Publication rates and interest in rheumatic fever has diminished over the last 30 years. Because of this decline, many physicians are only vaguely aware of the disorder. Additionally, the fear of antibiotic resistance has influenced theCenterofDisease Control to suggest a significant decrease in the use of antibiotics by physicians. Although extremely valid for the future health and well-being of the population, such policies must be examined for each individual case carefully. The American Heart Association prescribes long-term antibiotic prophylaxis as the only current treatment; however literature reviews indicate that such therapy is rarely used. Therefore individuals diagnosed with rheumatic fever are not being treated. Additionally, because many physicians are not routinely testing for streptococcus or early signs of endocarditis, it is likely that cases of rheumatic fever will increase in the future, and many individuals may not be diagnosed until sever damage or morbidity occurs. Physician education and clear revised guidelines are necessary to ensure adequate treatment of individuals with rheumatic fever. Mis-understandings of the disease and how it should be treated by first responders (i.e. primary care providers and pediatricians) are discussed.

Cultural Competence in the Prevention and Treatment of Cancer: The Case of Blueberries in North America  [PDF]
Niobra Samuel-Peterson
Advances in Anthropology (AA) , 2013, DOI: 10.4236/aa.2013.32009

Berry and berry-type fruits have gained the title of “super fruits” in recent years due to their anti-disease promoting phytonutrients. While researchers have been hard at work isolating the mechanisms by which these bioactive chemicals influence the human body, scientists have largely ignored the influence of culture on the co-evolutionary relationship between berry fruits and humans. This paper explores the phytochemical makeup and cultural groundings of blueberries (Vaccinium corymbosum). Cultural and spiritual connections of northeastern Native American groups such as the Ojibwe tribe with blueberries have influenced the survival of both species. Considering the poor consumption of fruits across the United States, this paper presents the thesis that effectively changing the dietary habits of a population requires a multi-faceted approach where scientific knowledge of the benefits of fruits in addition to the history and sociocultural meaning of various fruits are taken into account. Moreover, this paper discusses the importance of sociocultural backgrounds (specifically of fruits) as a platform for strengthening cultural competence in order to more effectively communicate knowledge concerning the use of fruits in the prevention and treatment of various cancers.

Evaluating Subdivisions for Identifying Extraneous Flow in Separate Sanitary Sewer Systems  [PDF]
Adam Lanning, Eric W. Peterson
Journal of Water Resource and Protection (JWARP) , 2012, DOI: 10.4236/jwarp.2012.46037
Abstract: Separate sanitary sewer systems are designed to convey sewage waste from municipal areas to a central treatment facility; they are not designed to handle water associated with precipitation events. However, intercept of groundwater (infiltration) and of flows through manholes or unauthorized connections (inflows) introduces rainwater into the sanitary sewer system. Infiltration/Inflow (I/I) increases the costs associated with treatment and can create additional environmental problems. Identifying and quantifying the volume I/I can be complicated and costly. A simple quantitative method was developed to quantify the extent of I/I occurring in sewer sheds. The method uses measured sewer flows, water usage, precipitation values, and land cover data to calculate the volume of extraneous flows. To assess its utility, the method was used to compare two urban sewer sheds, Holiday Knolls and Eagle View. Both sewer sheds showed evidence of I/I in excess of 200 gallons per day per inch-mile of sewer pipe (gpd/in-mile). Holiday Knolls, the older subdivision had an average I/I of 1912 gpd/in-mile, while Eagle View had an average of 1143 gpd/in-mile. The devel- oped method provided simple means to calculate I/I and to identify sewer sheds in need of repair.
