Il lutto dell'oggetto, l'apocalisse dell'immagine
No full textL’appuntamento rappresenta l’occasione per un confronto intorno ad alcuni temi che hanno ispirato il lavoro teatrale e filosofico di Alessandro Fersen. Il tema della rappresentazione è uno degli elementi fondamentali della riflessione sull’opera d’arte e sulla sua natura. Nel caso del teatro esso è connaturato all’idea stessa di messa in scena. Ma il significato di questo termine non è scontato, allude alle realtà più profonde dei processi artistici. Si rappresenta ciò che può essere visto, e ogni rappresentazione nasce dalla visione che ne fornisce l’esperienza d’origine, dalla spinta dionisiaca che sta alla base di ogni procedimento genuinamente artistico
New Roads for Patron-Driven E-books:Collection Development and Technical Services Implications of a Patron-Driven Acquisitions Pilot at Rutgers
No full textCollection development librarians have long struggled to meet user demands for new titles. Too often, required resources are not purchased, while some purchased resources do not circulate. E-books selected through patron-driven plans are a solution but present new challenges for both selectors and catalogers. Radical changes to traditional technical services workflows are required, and selectors must modify the selection process to give more choice to the user. Rutgers University librarians have adopted an innovative new technical services workflow and collection-development model to manage a successful, patron-driven acquisitions project for e-books in the fields of math and computer science.This is an Accepted Manuscript of an article published by Taylor & Francis Group in Journal of Electronic Resources Librarianship on 13/12/2011, available online at: http://www.tandfonline.com/10.1080/1941126X.2011.627043

The politics of fashion: perceptions of power in female clothing and ornamentation as reflected in the sixteenth-century Chinese novel Jin Ping Mei
No full textThis thesis examines issues of female power and influence in sixteenth-century China focusing on how women and their roles were perceived in the changing social environment of the mid-late Ming dynasty. Using aspects of a New Historicist approach, information from contemporary literary and historical sources are analysed alongside each other. With its emphasis on the lives of women and preoccupation with the description of material objects, the late Ming novel Jin Ping Mei forms an important element in the thesis. China in the sixteenth century saw expanding urbanisation, the emergence of a new wealthy merchant class, increasing visibility of women and a questioning of traditional morality. Fashion consciousness, as one of the most conspicuous aspects of the new material culture, is a possible indicator of these trends. Traditional Western theories contend that fashion began in the particular context of Renaissance Europe. However, this study argues that a similar fashion awareness existed in China too, and was manifested in a competitive striving for social status, in this case specifically among women. In contrast to previous studies which downplayed the impact women had on defining traditional Chinese culture, this thesis demonstrates how women and their sartorial choices began to redefine the boundaries of material culture, influencing literati discourse which, in turn, re- influenced female behaviour
Give2Get: Forwarding in Social Mobile Wireless Networks of Selfish Individuals
No full textIn this paper, we present two forwarding protocols for mobile wireless networks of selfish individuals. We assume that all the nodes are selfish and show formally that both protocols are strategy proof, that is, no individual has an interest to deviate. Extensive simulations with real traces show that our protocols introduce an extremely small overhead in terms of delay, while the techniques we introduce to force faithful behavior have the positive and quite surprising side effect to improve performance by reducing the number of replicas and the storage requirements. We test our protocols also in the presence of a natural variation of the notion of selfishness-nodes that are selfish with outsiders and faithful with people from the same community. Even in this case, our protocols are shown to be very efficient in detecting possible misbehavior
On Active Attacks on Sensor Network Key Distribution Schemes.
No full textThis paper concerns sensor network key distribution schemes (KDS) based on symmetric-key techniques. We analyze the problem of active attacks against such schemes. By active attacks we mean those attacks, where the adversary can maliciously disturb the communication between the sensors. We observe that the active adversary that captured even a small number of sensors, can anyway get a full control over the network, no matter how strong the KDS is. Therefore we conclude that the best scheme in this context is the one based on the method of Blöm (1984) (which guarantees perfect secrecy of the keys, as long as the number of corrupted sensors is small). © 2009 Springer-Verlag
