The present article investigates the everyday experience of trade at the Ecuadorian-Peruvian borderlands, in Upper Amazonia, during the peak of the rubber boom (c. 1890-1912). The article looks at this complex and often misrepresented socioeconomic process from the perspective of micro-history. More specifically, the paper offers a rhythmanalysis (Lefebvre) of Amazonian trade, and brings to the surface important undercurrents of modern Amazonian history, such as widespread low-level corruption and indigenous agency. It is argued that native mobility during the rubber boom was largely voluntary. In this period, however, the natives became more dependent on manufactured goods. Finally, attention is paid to the everyday practices of traders and government officials in their attempts to profit from the rubber industry. Make do and cunning were their most successful strategies of domination. The microanalysis of economic rhythms opens up innovative avenues of research into the mundane cultural fabric of large-scale processes. The primary sources of this investigation include archival and contemporary published materials, many of which have never been studied before.
An application of screw theory to the kinematic analysis of a Delta-type robot
Jaime Gallardo-Alvarado,Albert L. Balmaceda-Santamaría,Eduardo Castillo-Castaneda 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.9
This paper reports on the kinematics of a translational parallel manipulator whose topology is close to the architecture of the famousDelta robot. The displacement analysis is presented in closed-form solution by applying a new strategy based on the unknown coordinatesof a point embedded to the moving platform. The input-output equations of velocity and acceleration of the robot are systematicallyobtained by resorting to reciprocal-screw theory. The singularities of the mechanism are explained through the input-output equation ofvelocity. Finally, a numerical example is provided to show the application of the method.
Reassessing Contextualization from an Educational Perspective
Jaime M. Kang 한국기독교교육정보학회 2009 Journal of Christian education information tech Vol.0 No.16
Living in a global community and confronting people of diverse backgrounds, Christian educators often find themselves busy translating the gospel into the concepts or ideals relevant and meaningful to the people in their own culture and situation. Nevertheless, this effort, known as contextualization, has not received as much attention in the field of Christian education as in missiology and theology. For this very reason, the writer has attempted to reassess contextualization from a Christian education perspective by doing research on three things: first, the relevance of contextualization in educational ministry; second, the potential areas of contextualization in educational ministry; and third, the significance of contextualization in the educational field. The underlying intention of this paper is to show how urgent the task of contextualization is within the faith community around the global world.

This work deals with the inverse–forward kinematic analysis of a symmetric parallel manipulator equipped with a rotary actuator generator of three independent translations and one rotation motion. The closure equations of the displacement analysis are easily formulated based on the unknown coordinates of two points embedded in the moving platform. The input–output equations of velocity and acceleration of the robot are systematically obtained through the reciprocal-screw theory. The pseudo-kinematic pairs that connect the limbs to the fixed platform and a passive kinematic chain connected to the robot manipulator eliminate the handling of rank-deficient Jacobian matrices, which is an undisputable advantage from the computational point of view. Furthermore, this strategy allows the use of the Lie algebra se(3) without the inherent restrictions associated with the limited mobility of the robot.
Faith Integration as a Way of Knowing in Higher Education
Jaime M. Kang 한국기독교교육정보학회 2007 Journal of Christian education information tech Vol.0 No.12
Learning shaped and formed by faith results in living that is shaped and formed by faith. The integration of faith and learning forms the foundation of Christian higher education and shapes its purpose and goal. Some would see faith and learning as contradictions that cannot exist together. Others would try to blend those that seem to be contradictions. We, Christian educators, on the other hand, maintain boldly that faith and learning must be held together. This is so because there can be no authentic Christian higher education without the marriage of these essentials. A task of a Christian university is to help a new generation think Christianly in order to impact the world for good with the truth of the gospel. For this outcome, the writer intends to call for special attention among Christian educators on the integration of faith and learning as a way of knowing in higher education in this paper. This objective is to be accomplished by doing the following: giving an overview of the key concepts of faith integration, explaining the epistemological understanding of knowing, and giving a brief study on the nature of higher education.
Tissue Culture and Micropropagation of Tree Peony (Paeonia suffruticosa Andr.)
Jaime A Teixeira da Silva,Miaomiao Shen,XiaoNan Yu 한국작물학회 2012 Journal of crop science and biotechnology Vol.15 No.3
Tree peony (Paeonia suffruticosa) is one of China’s most traditional flowers. It is also one of the most remarkable flowering ornamentals with a rich history of breeding. The speed and success of propagation have always been a major concern for breeders and cultivators. Tissue culture is one of the few effective methods to overcome these inherent difficulties. This article reviews advances made on various aspects of tree peony tissue culture and micropropagation, including the in vitro culture of buds, stem apex, leaves and petioles, sexual embryos and ovules, somatic embryos, anther and callus. Since the vast majority of literature is published in Chinese, this review provides a unique and valuable resource and spring-board from which to initiate or further studies related to in vitro culture of tree peony.
