Há um grande interesse em restringir a ampla gama e vasto domínio dos possíveis temas que poderiam ser ensinados sobre astronomia em uma estrutura gerenciável. Embora não haja nenhum currículo nacional obrigatório nos Estados Unidos, uma análise dos três esforços nacionais recentes para criar uma sequência apropriada de conceitos de astronomia por idade para serem ensinados nas escolas primárias e secundárias revela uma considerável falta de consenso a respeito de quais conceitos são mais apropriados para cada idade e quais tópicos devem ser cobertos. O esquema de padronização mais recente para a educação científica dos EUA, o Next Generation Science Standards (Padrões em Ciência: Nova Geração), sugere que a maioria dos conceitos de astronomia devem ser ensinados apenas nos últimos anos de educação do aluno; e no entanto  foi recebido com críticas consideráveis. Uma comparação dos esquemas de aprendizagem da astronomia nos Estados Unidos e uma breve discussão das críticas levantadas podem proporcionar aos educadores de astronomia internacionais dados de comparação na formulação de recomendações em suas próprias regiões.

The phenomenal growth of penal confinement in the United States in the last quarter of the twentieth century is still a public policy mystery. Why did it happen when it happened? What explains the unprecedented magnitude of prison and jail expansion? Why are the current levels of penal confinement so very close to the all-time peak rate reached in 2007? What is the likely course of levels of penal confinement in the next generation of American life? Are there changes in government or policy that can avoid the prospect of mass incarceration as a chronic element of governance in the United States? This study is organized around four major concerns: What happened in the 33 years after 1973? Why did these extraordinary changes happen in that single generation? What is likely to happen to levels of penal confinement in the next three decades? What changes in law or practice might reduce this likely penal future?

The United States Department of Energy’s Next Generation Nuclear Plant (NGNP) Advanced Gas Reactor (AGR) Fuel Development and Qualification Program will be irradiating up to nine low enriched uranium (LEU) tri-isotopic (TRISO) particle fuel (in compact form) experiments in the Advanced Test Reactor (ATR) located at the Idaho National Laboratory (INL). The ATR has a long history of irradiation testing in support of reactor development and the INL has been designated as the United States Department of Energy’s lead laboratory for nuclear energy development. These irradiations and fuel development are being accomplished to support development of the next generation reactors in the United States, and the irradiations will be completed over the next five to six years to support demonstration and qualification of new TRISO coated particle fuel for use in high temperature gas reactors. The goals of the irradiation experiments are to provide irradiation performance data to support fuel process development, to qualify fuel for normal operating conditions, to support development and validation of fuel performance and fission product transport models and codes, and to provide irradiated fuel and materials for post irradiation examination (PIE) and safety testing. The experiments, which will each consist of multiple separate capsules, will be irradiated in an inert sweep gas atmosphere with individual on-line temperature monitoring and control of each capsule. The sweep gas will also have on-line fission product monitoring on its effluent to track performance of the fuel in each individual capsule during irradiation. The first experiment (designated AGR-1) started irradiation in December 2006 and completed a very successful irradiation in early November 2009. The second experiment (AGR-2) is currently being fabricated and assembled for insertion in the ATR in the early to mid calendar 2010. The design of test trains, the support systems and the fission product monitoring system used to monitor and control the experiment during irradiation will be discussed. In addition, the purpose and differences between the first two experiments will be compared, and updated information on the design and status of AGR-2 is provided. The preliminary irradiation results for the AGR-1 experiment are also presented.

This chapter discusses figure skating in the 1960s. In 1961, the entire U.S. World team died in a plane crash on the way to Prague. One year later, two skaters from former teams, Barbara Ann Roles and Yvonne Littlefield, traveled to Prague as part of an otherwise inexperienced team of American skaters. Only one new member of the 1962 team, Scott Allen, would ever win a World or Olympic medal, but collectively the team provided the foundation on which the United States built its next generation of international champions. While the United States lost its current best skaters in the crash and was thrust into the necessity of developing new ones, across the skating world, a largely new slate of skaters appeared at the 1962 World Championships. Three of the men, Canada's Donald Jackson, Germany's Manfred Schnelldorfer, and France's Alain Calmat, were destined to become World champions.

Life stories such as memoirs reflect the interplay of autobiographical reasoning, and collective remembrance at a time and in a place where memoirs are written. Using this perspective for understanding life-writing, I discuss memoirs written by two women who were formerly internees in the Nazi extermination camp of Auschwitz-Birkenau. Olga Lengyel (1909–2001) lost her entire family in the camp and wrote her memoir in Paris just after the war. Her account describes the atrocities that she observed with few reflections on her own experiences. Mira Ryczke Kimmelman, (1923–) wrote her memoir more than half a century later as an emigre to the United States after the war where she and her husband raised their children and where she is presently an active participant in the survivor community. Her memoir is written as what Tomkins and McAdams have portrayed as a characteristic American redemptive account of successfully overcoming adversity. Following a happy childhood and suffering through the Shoah, Mira Kimmelman is a generative mentor who lectures on her experiences and leads tours for young people back to her homeland. She is concerned that the next generation be spared the suffering of the Shoah.

The United States Department of Agriculture downgrades on the order of 17% of all Swiss cheese produced in the United States due to defects. Many of these defects are related to improper eye formation, number, distribution, or size; leading to an industry loss of over $69 million per annum. The microbiome in Swiss-type cheeses plays a significant role in eye development due to production of organic acids and gaseous emissions contingent on bacterial abundance and phenotype. The relationship between bacteria and the organic acids they produce leading to Swiss cheese defects can be correlated using Next-generation sequencing and high-performance liquid chromatography coupled with UV-Vis and mass spectrometry, respectively. From two processing facilities, Next-generation sequencing identified bacterial genera Lactobacillus and Propionibacterium to be associated with split/cracked cheese defects, and Clostridium sensu stricto 12, Propionibacterium, and Lactobacillus to be associated with irregular Eye formation/distribution (or collapsed eye formation) defects in Swiss cheese. Also identified through Next-generation sequencing was the genera "Candidatus Berkiella", Propionibacterium, and Lactobacillus to be associated with blind defects in Swiss cheese. Chromatographic separation and identification of organic acids provided evidence that lower levels of acetic and propionic acids were found in the split/cracked cheese samples; lower abundance of acetic, lactic, propionic and butyric acids were found in blind cheese samples (while a higher abundance of citric acid was found); and lower concentrations of citric, acetic, and propionic acids were found in irregular eye distribution samples. From these data, it can be concluded that Swiss cheese monitoring for bacteria in the genera Lactobacillus, Propionibacterium, Clostridium sensu stricto 12, and "Candidatus Berkiella" can be used as a predictor of three types of cheese defects before and during long storage times leading to inferior product resulting in losses to the processor while organic acid monitoring results proved to be inconclusive.

Next-generation sequencing has led to an exponential increase in the number of genomes deposited in public repositories. This growing volume of information presents opportunities to track the prevalence of genes conferring antimicrobial resistance (AMR), a growing threat to the health of humans and animals.
