The study was carried out with respect to three income groups. A total of 36 households (12 from each income groups) were assessed using different participatory appraisals through semi-structured questionnaires. A special type of indigenous knowledge on housing pattern and food habit was explored in the Mro community, which correspond to the severe dependence on forest resources.展开更多

Considering the multi-segment and multi-rate features of HAS, this paper proposes a buffer-driven resource management(BDRM) method to enhance HAS quality of experience(QoE) in mobile network. Different from the traditional methods only focusing on base station side without considering the buffer, the proposed method takes both station and client sides into account and end user's buffer plays as the drive of whole schedule process. The proposed HAS QoE influencing factors are composed of initial delay, rebuffering and quality level. The BDRM method decomposes the HAS QoE maximization problem into client and base station sides separately to solve it in multicell and multi-user video playing scene in mobile network. In client side, the decision is made based on buffer probe and rate request algorithm by each user separately. It guarantees the less rebuffering events and decides which HAS segment rate to fetch. While, in the base station side, the schedule of wireless resource is made to maximize the quality level of all access clients and decides the final rate pulled from HAS server. The drive of buffer and twice rate request schemes make BDRMtake full advantage of HAS's multi-segment and multi-rate features. As to the simulation results, compared with proportional fair(PF), Max C/I and traditional HAS schedule(THS) methods, the proposed BDRM method decreases rebuffering percent to 1.96% from 11.1% with PF and from 7.01% with THS and increases the mean MOS of all users to 3.94 from 3.42 with PF method and from 2.15 with Max C/I method. It also guarantees a high fairness with 0.98 from the view of objective and subjective assessment metrics.展开更多

Text analyzes the two main themes. Firstly, the treatise attempts at a philosophical analysis of the categories--speed and disaster in Paul Virilio dromology. The development of high technical speeds would thus result in the disappearance of consciousness as the direct perception of phenomena that inform us of our own existence. Dromological research by Paul Virilio presents a critical analysis of the consequences for our perception and logistics caused by polar inertia, inertia of absolute speed. The second part of the study discusses the word--accident. Accident is inseparable from the speed. Virilio＇s texts deal with the impact of speed, disaster, and accident on the contemporary world. Speed and accident create a new form of uncertainty in society.展开更多

Borges＇s poetics of reading and dreaming require another poetics of the work as a text that calls attention to its own artifice. In reading Borges＇ fiction, the separate roles and identities of reader, writer, and work of fiction merge and exchange roles, powers, and identities and are transformed into a single act of dreaming, which assumes cosmogonic and apocalyptic risks. In the dominant role given to the reader, the work of fiction as an object or work of art does not exist unless it is read. There is no determinate text, only a version of our own we re-write and invent every time we read the text. The author＇s reading is not a spontaneous evocation of vision, but an artifice, as artificial as the writing of the fiction. As writers and readers we are composed of texts and schemata, alphabets and artifacts, not merely mental perceptions and ideas. The reader requires a prior text to copy, translate, and recreate, and that text only exists as a fictional microcosm in so far as it is being read by a Reader who is able to actualize the revelation only imminent within it.展开更多

The refurbishment of the listed complex was studied to provide knowledge on how a process for refurbishing heritage buildings can be carried out successfully, as refurbishment of heritage buildings is often a complicated process. The process shows how to choose, evaluate and implement measures creating synergy between the interests of preserving heritage values and to develop affordable refurbishment that meets the requirements for the future use of the building. The refurbishment followed included restoration, energy upgrading and refurbishment of the individual buildings that make up the listed complex. The process focuses on the cooperation and dialogue between the parties involved. F estningens Materialgard is a case study where the Heritage Agency, the Danish Working Environment Authority and the owner as a team cooperated in identifying feasible refurbishment measures. Through the process the owner was supported by architects and engineers. Focus is put on how, to identify potential energy savings and, to decide on energy upgrading measures when refurbishing and restoring listed buildings. The refurbished Faestningens Materialgard is visualized in photos.展开更多

Even worse were attempts to force Chinese literature into the Procrustean bed of Western literary propositions. How can Chinese literary theory be used more effectively to interpret native literature and culture, or Chinese experience？ How can it throw off Western theoretical models and become a component of the Chinese nation＇s own narrative？ Reconstruction of the discourse system of Chinese literary theory must be a high priority. It is a complex project, one that necessarily entails stepping on to the discourse platform of modernity, accepting various kinds of open dialogue, and thence envisioning a new form of discourse system set amid multilayered overlapping perspectives and even the challenge of different ideas.展开更多

First, my work will briefly survey the history of the Chinese tradition called Dachunniu （hitting the spring ox） and that of the pifiata, speculating on the similarities and possible linkage between the two traditions. Second, it will conduct a textual investigation of the book attributed to Marco Polo and its historical context in order to examine the alleged Chinese connection of the pifiata. I argue that the practice of the pifiata can be tentatively attributed to the Chinese custom of the Dachunniu and that Marco Polo might have played a key role in the transmission of the tradition, but any definitive conclusion is dependent on additional evidences, textual, or material.展开更多
