The 1911 Revolution in China, the Chinese Calendar, the Imaginary Qi and Healing: Translating Li Fa into an Australian Chinese Calendar and into an English Edition of the Northern Hemispherical Chinese Calendar  [PDF]
Rey Tiquia
Chinese Studies (ChnStd) , 2012, DOI: 10.4236/chnstd.2012.13005
Abstract: One of the consequences of the 1911 Revolution in China was the political demise of the traditional Chinese calendar li fa. As China adopted the Gregorian Calendar, the modern Western time system replaced the premodern Chinese time system. This resulted in the fracturing of the ‘unified field of all existence’ of various premodern traditional Chinese practices including traditional Chinese medicine (TCM). Using a new understanding of science and other knowledge systems as local and situated, I translate and adapt the traditional Chinese calendar to the conditions of the Southern Hemisphere in Australia. An English rendition of the Northern Hemisphere Chinese Calendar is also made. I see the concepts of qi, yin and yang, the five-elements/agents/phases wu xing and the Eight Trigrams/Hexagrams of the Book of Changes yi jing as imaginaries, which animate both our human bodies and other bodies in the universe. Thus, in commemoration of the centenary of the 1911 Revolution or Xin Hai Ge Ming in China, we celebrate the birth of a Chinese Calendar in the Southern Hemisphere—The Australian Chinese Calendar.

Abstract: introduction. enteric viruses have been implicated in acute diarrheal disease, food-borne disease, hepatitis a and meningitis outbreaks, in which water was the vehicle of transmission. objective. a concentration method was standardized for the detection of enteric viruses in drinking water. materials and methods. twenty liters of water were concentrated to 6 ml by filtration and tangential ultrafiltration. viral solutions of 20 l each were prepared at 1, 10, 50 and 100 tcid50 of sabin poliovirus type 1 as positive controls. viral particles were recovered by tissue culture and detected by conventional polymerase chain reaction (pcr), according to the international standards recommended by the enterovirus laboratory at the centers for disease control and prevention, atlanta, ga. results. all positive controls showed cytopathic effect on l20b and rd cells and were amplified by conventional pcr directly from samples. negative controls did not show any amplification or viral cytopathic effect. conclusions. tangential ultrafiltration for concentrating viruses proved to be a fast, efficient recovery and reproducible. it has the advantage of allowing the detection (at the 1 tcid50 level) and identification of viruses by rt-pcr and the demonstration of viral infectivity by tissue culture.
Spanish researchers’ perceived difficulty writing research articles for English-medium journals: the impact of proficiency in English versus publication experience

Ibérica , 2012,
Abstract: Previous quantitative studies suggest that the burden researchers who use English as an additional language perceive when writing research articles (RAs) for publication in English (as L2) is 24% greater than the burden they perceive when they write RAs for publication in their L1. It remains unclear precisely which aspects of research article (RA) writing in English present these writers with the greatest challenge and just why they perceive this increase in difficulty. A structured questionnaire comprising thirty-seven questions about researchers’ publication experiences in scientific journals in English and in Spanish was designed and sent out to all (n = 8,794) Spanish postdoctoral researchers at one research-only institution and four universities in Spain, yielding responses from 1,717 researchers. Our first results show that the discussion is the section that is perceived as more difficult to write for English-medium journals, across the four broad knowledge areas in a way that cannot be fully explained by their lower level of proficiency in English (as L2). This article proposes the rhetorical transfer hypothesis as a possible explanation for their additional difficulty. Our results also reveal that their increased perceived difficulty writing RA discussions in English (as L2) does not decrease noticeably until Spanish researchers report high or very high levels of proficiency in English (as L2) for academic or general purposes or have published on average at least 37 RAs as corresponding author in English-medium journals over the last ten years. Implications for English for Academic Purposes (EAP) research and pedagogy are discussed.

Abstract: The importance of associability is being increasingly stated when the present ways of production of the knowledge are analyzed. Different organizational levels exist in the context of scientific research. Among them, research groups constitute one of the most generalized modalities of association. In this article we analyze conceptual and practical aspects which are considered when it comes to identify the nature and characteristics of research groups, as well as their differences with other modalities of scientific association, such as research teams. We emphasize the functional and dynamic character of research groups, which go through different stages in their evolution. We conclude that research groups must be considered as functional organizational units, instead than structural units. This has important consequences for the policies of promotion of research groups and for the consideration of groups on the part of research institutions. La importancia de la asociabilidad se está poniendo crecientemente de manifiesto cuando se analizan los actuales modos de producción del conocimiento. Existen diferentes niveles organizativos en el ámbito de la investigación científica, entre los que los grupos de investigación constituyen una de las modalidades de asociación más generalizadas. En este artículo se analizan los aspectos conceptuales y prácticos que se plantean cuando se trata de identificar la naturaleza y las características de los grupos de investigación, así como las diferencias con otras modalidades de asociación, como los equipos de investigación. Se enfatiza el carácter funcional y dinámico de los grupos de investigación, que transitan por diferentes etapas en su evolución. Se concluye que los grupos de investigación se deben considerar más como unidades organizativas funcionales que estructurales, lo que tiene importantes consecuencias en las políticas de fomento de los grupos e incluso en su consideración en las instituciones de investigación.

Abstract: Introducción. Los virus entéricos se han visto implicados en brotes de enfermedad diarreica aguda, enfermedades transmitidas por alimentos, hepatitis A y meningitis aséptica, en los que el vehículo de transmisión del agente ha sido el agua. Objetivo. Estandarizar un método de concentración para la detección de virus entéricos en aguas de consumo. Materiales y métodos. Se concentraron 20 litros de agua a un volumen de 6 ml mediante filtración y ultrafiltración tangencial. Como controles positivos se prepararon soluciones de 20 litros a concentraciones virales de 1, 10, 50 y 100 TCID50 (Tissue Culture Infectious Dose 50%) de Poliovirus Sabin de tipo 1. Las partículas virales fueron recuperadas por cultivo en células sensibles a la infección e identificadas por amplificación del genoma viral mediante reacción en cadena de la polimerasa, siguiendo los estándares internacionales de los Centers for Disease Control and Prevention (CDC) de Atlanta. Resultados. Todos los controles positivos causaron efecto citopático en células de rabdomiosarcoma y L20B y fueron detectados por RT- PCR (Real Time- PCR) convencional, directamente de las muestras. Los controles negativos no mostraron efecto citopático ni amplificación viral por RT-PCR. Conclusiones. La ultrafiltración tangencial mostró ser un método rápido y eficaz al recuperar virus desde una TCID50, además de ser reproducible y sencillo. Tiene la ventaja de permitir la detección de su capacidad de contagiosidad viral por el cultivo celular, y la identificación por RT-PCR. Introduction.

Abstract: Through the survey Research activities in the R&D system in Earth Sciences in Spain (1990-1994)>>, information about different aspects of the professional activity of Spanish researchers in this field has been retrieved, as well as their opinion about prevailing research evaluation criteria. Starting from survey's results, we discuss the suitability of the present Spanish scientific evaluation system for assessing research activity of said researchers. Results show scientist's disagreement with the prevailing evaluation procedures and criteria. More than 70 % of both University and CSIC researchers consider that evaluation criteria are inappropriate or unacceptable, being this percentage significantly higher than the obtained from scientists belonging to other institutions. Disagreement with evaluation criteria is significantly lower among authors that only publish in foreign journals. Positive correlation has been found between opinion about evaluation criteria and the level of consolidation and stability of research teams. Main cause of disagreement is concerned with the over-valuation of papers published in SCI journals and the scarce consideration given to high quality papers published in serious domestic journals and to other scientific contributions. Results suggest that the evaluation system could have been detrimental to researchers working in some scientific fields, but does not seem to have discriminate among basic and applied research or among research of local or national interest and those more internationally-oriented. The research evaluation system should consider the idiosyncrasy of the different scientific fields, as well as their particular and distinctive characteristics and dynamics. It should take into the adequate consideration quality scientific work that, despite being of particular importance in fields as Earth Sciences, is not published in SCI joumals. A través de la opinión expresada por los propios investigadores, se discute la idoneidad del actual sistema espa ol de evaluación de la actividad investigadora, para su aplicación en el campo de las Ciencias de la Tierra. Dicha opinión ha sido obtenida a través de la encuesta Actividades de investigación realizadas en el Sistema de I+D en Ciencias de la Tierra en Espa a, 1990-1994 , que recoge información sobre distintos aspectos de la actividad profesional de los investigadores espa oles en este campo. Los resultados muestran su desacuerdo con los criterios y el procedimiento de evaluación actualmente vigentes. Más del 70 % tanto de los profesores universitarios como de los i

Journal of Geoscience and Environment Protection (GEP) , 2016, DOI: 10.4236/gep.2016.46009
Abstract: The study was conducted to determine the socioeconomic impact two (2) Small Water Impounding Projects (SWIPs) namely Burgos SWIP in Cabarroguis and Divisoria Norte SWIP in Maddela, both in the Province of Quirino, Philippines. The study made use of structured questionnaire to gather the socio-demographic profile and determined the socioeconomic impact of the SWIPs to the farmer-beneficiaries. Most of the farmer-beneficiaries of Burgos and Divisoria Norte SWIPs are male, 40 - 59 years old, married, have below four household members, Roman Catholic, high school graduates and some are members of cooperatives. They are rice farmers, and have attended one to two training courses related to farming and own a 1.00 to 1.99 hectares farm. “Utilization of water in the reservoir for other purposes like wallowing pool for carabaos” and “integration of fish production and livestock raising” were the identified benefits at the farmer’s level while “introduction of new techniques in farming by the Local Government Units,” “availability of cheap fish and additional income as a result of integration of fish production” and “construction of better roads” were the identified benefits at the community level. The SWIPs have positive impact as confirmed by the increase in the annual mean yield and in the annual gross income of the farmer-beneficiaries. It contributed a significant increase of 2.14 tons/year in the mean yield generating an additional income of PhP 32,113.64 for Burgos SWIP. On the other hand, it contributed a significant increase of 2.08 tons/year giving an additional income of PhP 31,313.60 for Divisoria Norte farmer-beneficiaries. The result of this study will provide strategic information to policy makers of agricultural and irrigation agencies on the existing weaknesses of irrigation systems in the country and determine in a more quantifiable terms level of potential improvement and investment targets.
