More powerful cluster randomized control trials
No full textBalanced experimental designs, in which the number of treatment and control units are the same, do not maximize power subject to a cost constraint when treat- ment units are more expensive than control ones. Despite this, such balanced designs are the norm in economics. This paper describes methods to optimally choose the number of treatment and control clusters, and the number of units within treatment and control clusters, allowing for full flexibility. We use three archetypal examples from the development literature to illustrate the magnitude of the power gains, which lie between 8.5 and 19 percentage points.<br/

Parrhesía e loucura no exemplo de Estamira
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Filosofia, Florianópolis, 2015.Um autor como Michel Foucault (1926-1984), ao apresentar um estudo extenso sobre saber, poder e ética, deixa o leitor com dúvidas e indagações: O sujeitado ao poder não teria como se contrapor à submissão? O poder psiquiátrico, com seus saberes sobre a loucura, seria tão poderoso assim? Na tentativa de responder estas questões, estabeleceu-se como objetivo geral investigar a parrhesía e a loucura no exemplo de Estamira. Como pressuposto metodológico, optou-se pelos escritos de Michel Foucault sobre a temática da loucura. Na análise do documentário a respeito de Estamira, produzido por Marcos Prado em 2004, foram analisadas algumas cenas, fundamentando-se, sobretudo, em seus últimos escritos, de 1980 a 1984, do Collège de France. O pensamento último de Foucault evidencia uma preocupação histórica do que seria o cuidado de si e a parrhesía no período da Grécia Clássica, por volta do séc. IV a.C., o período helênico romano séc. I e II d.C. e os primeiros cristãos (IV a V d.C.). O autor consegue perceber, na antiguidade grega, a existência de uma subjetividade que não segue normas, a qual se torna uma prática de liberdade (práticas ascéticas), uma busca de como dizer a verdade (parrhesía) que leva a uma constituição ética atrelada à estética da existência da vida do sujeito. Conclui-se, com base nas análises históricas foucaultianas, que o exemplo de Estamira nos remete a uma ?ontologia do presente?, ?ontologia dos discursos verdadeiros?, uma concepção de subjetividade, de verdade e de filosofia de vida para o indivíduo, com sua loucura, transformar sua vida e ser diferente do que é, governando a si mesmo pela parrhesía, ser franco, falar a verdade.Abstract : An author such as Michel Foucault (1926-1984) when presenting an extensive study of knowledge, power and ethics, leaves the reader with doubts and questions: The subjected to power could not possibly oppose itself from submission? The psychiatric power, with its knowledge about insanity, would be that powerful? In the attempt to answer these questions, it was established as a general objective to investigate the parrhesia and insanity in the case of Estamira. For the methodological presupposition, it was chosen the writings of Michel Foucault on the theme of madness. In the documentary film analysis about Estamira, produced by Marcos Prado in 2004, some scenes were analyzed mostly based in his later writings, from 1980 to 1984, from the Collège de France. The final thought of Foucault reveals a historical concern of what would be the self care and the Parrhesia in the Classical Greece period from around the IV century B.C., the Roman Hellenistic period during the I and II century A.D. and the early Christians (IV to V A.D.). The author is able to perceive that in Greek antiquity, the existence of a subjectivity that does not follow rules, which turns to a practice of freedom (ascetic practices), a search for how to tell the truth (parrhesia) leading to an ethical constitution tied to the aesthetics of existence of the subject´s life. The conclusion is, based on Foucault's historical analysis, that the example of Estamiranos refers to an "ontology of the present", "ontology of real discourses," a conception of subjectivity, truth and life philosophy for the individual, with his insanity, to transform his life and be different than it is, ruling himself through parrhesia, be honest and to tell the truth
Caracteristicas fitoquímicas y capacidad antioxidante in vitro de Aloe vera, Plukenetia volubilis, Caiophora carduifolia, Cecropia membranácea
No full textIntroduction. Antioxidants have shown chemopreventive potential in degenerative, inflammatory, autoimmune, oncology and respiratory distress associated pathologies. Objective. To assess the phytochemical and antioxidant properties in vitro by DPPH and ABTS method. Design. Observational analytical. Location. Laboratory of Experimental Pharmacology, Faculty of Medicine, Universidad Nacional Mayor de San Marcos, Lima, Peru. Biological/Chemical Material. Aloe vera leaves, Plukenetia volubilis seeds, Caiophora carduifolia leaves-stalks, Cecropia membranacea leaves. Interventions. Observation and analysis of the antioxidant capacity by DPPH-method mean effective concentration (EC50) of the extracts and trolox equivalent antioxidant capacity by the ABTS method. Main outcome measures. Phytochemical preliminary march, antioxidant percent uptake inhibition by DPPH radical, determination of equivalent trolox/gextract. Results. Cecropia membranacea presented more secondary metabolites, alkaloids, saponins, flavonoid compounds; required smaller dosage to achieve the antioxidant effect (EC50 = 0.159 mg/mL) in attracting DPPH radical; achieved the best antioxidant effect by ABTS method (5.834 uM trolox/g). Caiophora carduifolia (0.87 mg/mL – 0.44 mg/mL) had trolox similar effects (p> 0.05). Aloe vera and Plukenetia volubilis also had antioxidant dose dependent effect. Conclusions. Concentration dependent in vitro antioxidant effect has been shown, higher with Cecropia membranacea and Caiophora carduifolia and lower with Aloe vera and Plukenetia volubilis.Introducción: Los antioxidantes han demostrado potencial quimioprotector en patologías degenerativas, inflamatorias, autoinmunes, oncológicas y asociadas al distrés respiratorio.

70 años de creación de la Facultad de Química e Ingeniería Química – Universidad Nacional Mayor de San Marcos
No full textEl 24 de abril de 2016, la Facultad de Química e Ingeniería Química de la Universidad Nacional Mayor de San Marcos conmemorará el septuagésimo aniversario de su creación. Es por ello que debemos remontarnos a hechos históricos importantes que menciono a continuación:Desde la creación de la Facultad de Ciencias en 1855, esta tuvo varias secciones: Sección Matemática, Sección Biología, Sección Mineralogía y Sección Físico-Química. Los egresados se titulaban como Licenciados en Matemática, Biología, Mineralogía y Licenciados en Estudios Físico-químicos, y, no es sino hasta el año 1935 que el Decano de la Facultad de Ciencias, y posteriormente Rector de la UNMSM, Dr. Godofredo García Díaz, crea la especialidad de Químico, profesión con la cual, en diciembre de 1937 se titularon los primeros Químicos sanmarquinos: Agustín Iza Arata, Aníbal Llanos Pineyro, Adolfo Bragagnini Zapater, Alberto Enriquez Vera, César Gamarra Cangahuala, Julio Swayne López, Raúl Martinot Mendiola, Rómulo Zapata Valle, Valentín Sanabria Peña, Armando Martens Bonnatti, Mario Costa Chávez, Francisco Balbi Basauri, Hoshi Sakurai, Dante Binda Aranda, Felipe Duffaut Uribe y Carlos Mindreau Goycochea. Los primeros Químicos titulados pertenecían a la sección Fisico-Química de la Facultad de Ciencias de la Universidad Nacional Mayor de San Marcos.La Sociedad Química del Perú, en el año 1945, en sesión de Consejo Directivo presidido por el Dr. Artidoro Alvarado Garrido e integrado por los miembros: Dr. Víctor Cárcamo Márquez, Quím. Farm. Juan de Dios Guevara Romero, Ing. Luis Bustamante Amir, Quím. Farm. Julio López Guillén, Ing. Luis Armas Berensohn y Quím. Mario Costa Chávez, promueve la creación de un Instituto de Química o Facultad de Química, en la Universidad Nacional Mayor de San Marcos, cuyos acuerdos son elevados a la Comisión Parlamentaria de Reforma Universitaria. En marzo de 1946, el Dr. Víctor Cárcamo Márquez, profesor de la Facultad de Ciencias y Diputado por Arequipa, proyecta en su Cámara la propuesta de creación de la Facultad de Química en la Universidad Nacional Mayor de San Marcos, la cual fue aceptada por la Comisión de Educación
The ethno-politics of water security: contestations of ethnicity and gender in strategies to control water in the Andes of Peru
No full text This thesis is the result of a multidisciplinary research which tries to explain water injustices and the threats to water rights access and control experienced by indigenous peasants of the Peruvian Andes. It attempts to contribute to the analysis of the interactions between ethnicity and gender, and to understand how these form an intrinsic part of the contemporary ethno-politics of water. It also critically analyses the role of state interventions and international financial aid programmes in irrigation development and peasant communities. For the purposes of this research, ethnography and ethno-history, complemented by data generated by means of action-research and an intensive literature study of records written by Spanish and indigenous chroniclers, have been used. Through the presentation and analysis of these written sources, and by carefully mapping and documenting existing water practices in the communities of the Colca Valley, located in the southern Andes of Peru, the thesis shows how water has played a role not only in livelihood strategies but also in shaping cultural identity and the socio-organizational and political dynamics of communities. Water has constituted a central resource in defining and re-defining ethnicity and gender in the Andes. Conversely, ethnicity and gender have also been constitutive elements of fair and secure access to water by supporting and creating power asymmetries and hierarchies in Andean communities throughout Peruvian history. The thesis shows how irrigation policies and interventions have created spaces and opportunities both for inclusion and exclusion, for contestation and struggles, as well as for the empowerment of marginalized people. Keywords: ethno-politics, water security, ethnicity, gender, water rights, cultural politics, modernization, irrigation development, large-scale irrigation, alternative development and resistance. </p
Courageous women in media: Marcos and censorship in the Philippines
No full textWhen Philippine President Ferdinand Marcos declared Martial Law in 1972, press freedom became the first casualty in the country that once boasted of being the 'freest in Asia'. Printing presses, newspaper offices, television and radio stations were raided and padlocked. Marcos was especially fearful of the press and ordered the arrest of journalists whom he charged with conspiring with the 'Left'. Pressured into lifting martial law after nearly 10 years, Marcos continued to censor the media, often demanding publishers to sack journalists whose writing he disapproved of. Ironically, he used the same 'subversive writings' as proof to Western observers that freedom of the press was alive and well under his dictatorship. This article looks at the writings of three female journalists from the Bulletin Today. The author examines the work of Arlene Babst, Ninez Cacho-Olivares, and Melinda de Jesus and how they traversed the dictator's fickle, sometimes volatile, reception of their writing. Interviewed is Ninez Cacho-Olivare, who used humour and fairy tales in her popular column to criticise Marcos, his wife, Imelda, and even the military that would occasionally 'invite' her for questioning. She explains an unwritten code of conduct between Marcos and female journalists that served to shield them from total political repression
Participação e processos político-organizativos: temas para o Serviço Social
