No full textFrom Pulitzer Prize-winning author Morris comes a revelatory new biography of Thomas Alva Edison, the most prolific genius in American historyThomas Alva Edison's invention of the first practical incandescent lamp 140 years ago so dazzled the world that it cast a shadow over his later achievements. In all, this near-deaf genius patented 1,093 inventions, not including those he left unlicensed for the benefit of medicine.Morris portrays the unknown Edison-- philosopher, futurist, chemist, botanist, wartime defense adviser, founder of nearly 250 companies-- while deconstructing the Edison of mythological memory. -- adapted from jacke

Thomas Edison: Success and Innovation through Failure [electronic resource] /
No full textThis book develops a systematic approach to the role of failure in innovation, using the laboratory notebooks of America's most successful inventor, Thomas Edison. It argues that Edison's active pursuit of failure and innovative uses of failure as a tool were crucial to his success. From this the author argues that not only should we expect innovations to fail but that there are good reasons to want them to fail. Using Edison's laboratory notebooks, written as he worked and before he knew the outcome we see the many false starts, wrong directions and failures that he worked through on his way to producing revolutionary inventions. While Edison's strengths in exploiting failure made him the icon of American inventors, they could also be liabilities when he moved from one field to another. Not only is this book of value to readers with an interest in the history of technology and American invention, its insights are important to those who seek to innovate and to those who employ and finance them.Chapter 1.

The importance of pairwork in educational and interdisciplinary initiatives
No full textAn early and prominent employee of Google, Georges Harik, recently made the assertion that pairs working together in startups are 20 times more productive than individuals working alone. The author has also personally experienced the boost of what is here termed pairwork in a university setting during the startup phase of several educational and interdisciplinary initiatives. The paper briefly explores pairwork in the history of technology and constructs both qualitative and little quantitative models of pairwork. The quantitative model under reasonable assumptions easily recovers Harik’s 20x boost. The paper also briefly examines the author’s recent experiences with pairwork in four interdisciplinary and educational initiatives
No Underskirts in Africa: Edison Carneiro and the "Lineages" of Afro-Brazilian Religious Anthropology
No full textThe article presents the folklorist, essayist, journalist and anthropologist Edison Carneiro (1912-1972) and situates him among the “lineages” or intellectual affiliations in the context of studies on Afro-Brazilian religious groups. Describing the life of Edison Carneiro, his relationship with American anthropologist Ruth Landes and his participation in the folkloric movement, I look to situate Carneiro among the various intellectual trends
found within the study of Afro-Brazilian religions. I argue that the author occupied an ambiguous position in terms of the African presence in the constitution of Afro-Brazilian religions, showing close proximities to Ruth Landes, Franklin Frazier, Ruth Benedict, Donald Pierson and Robert Park on the one hand, and Melville Herskovitz, Roger Bastide and Arthur Ramos on the other. Carneiro’s studies of Candomblé de Caboclo express this

Concentration camps American-style
No full textA brochure with a reprint of an article by Edison Uno originally printed in The Pacific Citizen Special Holiday Edition in 1974. The article discusses the forced evacuation and incarceration of Japanese Americans during World War II and the usage of the term "concentration camps" to describe the camps Japanese Americans were held. The article discusses the treatment and living conditions of incarcerees in the camps.The Horita Family Papers (1940-2010, undated) collection contains documents from the Horita family, a Japanese American family from the Los Angeles area. The collection focuses on married couple Chitoshi "Harry" Horita (1896-1990) and Marue Nakashima Horita (1901-1982) and their extended family and includes records of the family's incarceration at the Poston (Colorado River) incarceration camp, research into the family's history, photographs, and correspondence
Metodologia de análise de blocos de motores
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Mecânica.A indústria automobilística atual tem se preocupado muito em projetar motores que atendam à legislação criada para controlar o nível de emissão de poluentes. Desde então, a busca por motores de alto desempenho, com baixo consumo e reduzida emissão de poluentes é uma necessidade. Considerado um dos componentes mais importantes, e que agrega maior peso ao motor, o bloco tem sido o alvo principal de pesquisas na busca por motores mais eficientes. Os motores Diesel, que trabalham com elevadas taxas de compressão, necessitam de uma estrutura bastante rígida para suportar os esforços gerados durante a combustão dos gases. Seu rendimento e nível de emissões poderiam ser melhores com a utilização de maiores picos de pressão. Segundo alguns trabalhos, a utilização de materiais alternativos, como o ferro fundido vermicular ou CGI (Compacted Graphite Iron), tem possibilitado projetar motores com maiores pressões de combustão e/ou redução significativa de espessuras de parede, devido às suas melhores propriedades mecânicas quando comparadas às do ferro fundido cinzento. Neste trabalho, avalia-se o comportamento estrutural de um bloco de motor Diesel, submetido à ação de forças oriundas da montagem do cabeçote e das capas de mancal, pressão dos gases de combustão e forças de inércia, utilizando critérios de falha tradicionais (Tensão, deslocamentos e fadiga). As tensões e deslocamentos são determinados através de um modelo numérico constituído por ¼ do bloco. Os resultados são gerados por um software que utiliza o método dos elementos finitos (I-DEAS). A geometria deformada é utilizada para se estudar a ovalização nos cilindros e mancais, determinando-se a folga mínima final nestas regiões. Avalia-se também a utilização do ferro fundido vermicular para a obtenção de blocos de motores Diesel, onde são necessárias altas pressões de combustão, através de uma simulação sob uma pressão de combustão acima de 20 MPa. Nesta última, os coeficientes de segurança ainda são bastante elevados, mas a ovalização dos mancais pode comprometer a lubrificação
The Long Way of Knowledge Society
No full textI think, therefore I am. Our ancestors said Cogito, ergo sum, in a Latin form of Rene Descartes' expression "Je pense, donc je suis", in Discourse on Method (1637). The same did Thomas Davenport, when gave his book the title Thinking for a living. Probably he didn't prefer the direct form in English of the above mentioned expression: "I think, therefore I am", but one that in essence is more poetical and more anchored in the reality of the third millennium's early days, in the way that only thinking we can exist. The title is also a commercial one, because the previous ten books also basically referred to knowing or knowledge. They used the research done in the following fields: knowledge management, process management and innovation. The opening of his last book, a best seller of 2005, is also interesting. The author gives the first chapter the title 'What's a Knowledge Worker, Anyway?". We could draw the conclusion that after so much effort, including a publishing one, the author remains with the doubt on the terminology so much used at the end of the 2nd millennium and the beginning of the 3rd one or leaves an open way to the next volumes. It is not by chance that there are voices that say he might be the next Peter Drucker. The last one said that the future society would be the knowledge society (see also Managing in the Next Society, 2002).society, knowledge
Las concepciones de la educación intercultural bilingüe por los docentes en una institución educativa primaria en Apurímac: dilemas y posibilidades
No full textDesde una metodología cualitativa, esta investigación aborda la concepción de Educación Intercultural Bilingüe (EIB) por parte de los docentes en una institución educativa de nivel primario EIB en Apurímac – Perú. El principal hallazgo es que los docentes presentan conceptualizaciones dilemáticas en relación a la EIB, pues si bien van apropiándose de la propuesta de esta modalidad educativa también arrastran visiones que los acercan a un modelo de escuela civilizadora que ha primado históricamente en el Perú. Los docentes son críticos frente a la opresión del quechua, pero lo enseñan muy poco en la escuela; defienden que los estudiantes usen su vestimenta ancestral, pero también abogan por un uniforme único; reconocen la necesidad de trabajar con materiales locales en el contexto comunal, pero simultáneamente se alinean con los materiales tradicionales del MINEDU y deciden permanecer mayormente en sus aulas. Finalmente, los docentes promueven la interculturalidad, pero conceptualizan la cultura quechua como algo estático y del pasado. Este estudio muestra que estos dilemas (y rezagos de la escuela civilizadora) en los docentes se pueden explicar a partir de su propia vida y formación escolar, pues ellos mismos han sido víctimas de constante discriminación y racismo en este proceso.From a qualitative methodology, this research addresses the conception of Intercultural Bilingual Education (IBE) by teachers in an educational institution of primary level IBE in Apurimac - Peru. The main finding is that teachers present dilemmatic conceptualizations in relation to IBE, because although they are appropriating the proposal of this educational modality, they also have visions that bring them closer to a civilizing school model that has historically prevailed in Peru. Teachers are critical of the oppression of Quechua, but teach it very little in school; they defend the use of ancestral dress by students, but also advocate for a single uniform; they recognize the need to work with local materials in the community context, but simultaneously align themselves with the traditional MINEDU materials and decide to remain mostly in their classrooms. Finally, teachers promote interculturality, but conceptualize Quechua culture as something static and of the past. This study shows that these dilemmas (and lags of the civilizing school) in teachers can be explained from their own life and school training, as they themselves have been victims of constant discrimination and racism in this process
