Reviewing the Author-Function in the Age of Wikipedia
No full textIn Reviewing the Author-Function in the Age of Wikipedia, Amit Ray and Erhardt Graeff examine how wiki technology challenges traditional concepts of authorship and authority in knowledge production. The authors build on poststructuralist theory, particularly Roland Barthes\u27s Death of the Author and Michel Foucault\u27s concept of the author-function, to analyze how wikis destabilize individual authorship in favor of collaborative, community-driven content creation.
The essay argues that wikis represent a fundamental shift from the Romantic notion of the solitary author-genius to what they term the wiki writing process —a dynamic system where traditional roles of reader, writer, and editor blur into a unified community of users. Using Wikipedia as a primary case study, the authors demonstrate how the platform\u27s structure (article, discussion, and history pages) creates a digital palimpsest that archives all contributions while enabling continuous revision.
Through analysis of Wikipedia\u27s editing patterns and community oversight mechanisms, Ray and Graeff show how wikis embody poststructuralist principles in practice, creating what they call serial collaborations that exist in perpetual flux. The authors conclude that wikis represent an evolved form of textual production that realizes Foucault\u27s vision of discourse freed from traditional authorial constraints, offering new possibilities for collaborative knowledge creation while challenging established notions of intellectual authority and ownership
Innovating Airport Passenger Terminals: Determining the feasibility of new terminal concepts based on seamless flow technology
No full textThe continuing growth in air travel passengers, in combination with enhanced security regulations, has led to unsustainable situations at airports. In order to handle the future amount of air travel passengers while complying to security regulations and enhancing the passenger experience, the terminal system must be innovated. Seamless flow is a future end-to-end continuous, efficient and secure innovation which uses passenger biometrics for identification throughout the airport processes. Previous research is focused on fitting the new seamless flow technology in with the conventional airport processes. This research explores whether the biometric technology could lead to new, and feasible, passenger terminal concepts. Two new seamless flow concepts are constructed and assessed on their feasibility by conducting interviews with stakeholders, performing desk-research and executing a financial Cost-Benefit Analysis. The research findings indicate that the new technology could lead to feasible, efficient and experience enhancing passenger terminal concepts in comparison to the conventional terminal concept equipped with seamless flow technology. Thereby, the support of - and collaboration between - stakeholders, especially the border guard agency, is shown to be essential for the implementation of seamless flow technology on civil airports. Besides that, it is shown that more efficient terminal concepts could significantly benefit airports through increased commercial opportunities
CD38: A Novel Modulator of Morphine Antinociception in the Spinal Cord
No full textAuthor ManuscriptOpioid analgesics remain essential for managing moderate to severe pain, but the development of tolerance and hyperalgesia limits their clinical utility. CD38 is a multifunctional enzyme that generates calcium-mobilizing second messengers and plays a role in the supraspinal actions of opioids, yet its role in pain processing and spinal opioid effects remains undetermined. In this study, we investigated the function of CD38 in basal processing of acute heat and pressure noxious stimuli and spinal morphine antinociception using wild-type (WT) and CD38 knockout (CD38KO) mice of both sexes. CD38 enzymatic activity was highest in the spinal cord and predominantly localized to astrocytes. While CD38 deletion had no effect on baseline thermal or mechanical acute nociception, spinal morphine-induced antinociception was significantly reduced in CD38KO mice across both noxious modalities, with diminished magnitude and duration of response. Morphine-induced thermal hyperalgesia was attenuated in CD38KO females but not in males, indicating a possible sex-dependent role for CD38 in opioid-induced hyperalgesia. In contrast, spinal morphine tolerance developed similarly in both genotypes, suggesting these adaptations occur independently of CD38. Morphine administration did not alter spinal CD38 activity, and μ-opioid receptor expression was comparable between WT and CD38KO mice, indicating that CD38 modulates spinal opioid antinociception downstream or parallel to MOR signaling. These findings suggest that astrocytic CD38 plays a critical role in mediating opioid-induced antinociception without contributing to opioid-induced tolerance, highlighting its potential as a novel target for enhancing opioid efficacy.This work was funded by grants the National Institute of Neurological Diseases and Stroke (grant 1R21NS118499-01A1 to Alonso Guedes), National Institute on Drug Abuse (grant 1R36DA054455-01A1 to Ruth Quintana), and the University of Minnesota College of Veterinary Medicine Signature Program (grants 722, 667 to Alonso Guedes) and Graduate Student/Resident Program (grant 645 to Ruth Quintana).Quintana, Ruth; Singh, Dhananjay; Graeff, Richard; Titus, David; Guedes, Alonso.

De la survie à la reconnaissance: Ethnologie de personnes « sans logis » à Paris
No full textMention très honorable avec félicitations du jury à l'unanimitéThrough an ethnographic investigation, made in May 2006, fifty one cases of “homeless” people were studied. “Homeless” people are considered as people with no social, economic and personal conditions that allow them to have housing and as a result, they sleep “outside”, in a tent, under a bridge or in a house made with materials from the city. Using the ethnographic method - long duration of active observation, careful and discreet holding of a notebook to mention the daily observations, the author learns by physical experience, “by body”, the daily difficulties regarding the hygiene, the occupation of public places, and especially the efforts made to encounter the feelings of shame and “social contempt”, and to have access to some forms of recognition marked by the pride and the social esteem. Those people fight against the “social contempt” in different ways: some of them settle down in “corners” or in the margins of the city to be less visible, others try to erase all forms of precariousness on their bodies, and others join the manifestation of “Enfants de Don Quichotte” in fall 2006 in Paris. During these paths, going from survival to recognition, the people make us see and think about the logics of domination which are at the same time moral, physical, and cognitive and which characterize their social status.À partir d'une enquête ethnographique, effectuée de mai 2006 à avril 2008 à Paris, cinquantaine-et-une personnes « sans logis » sont étudiées. Sont considérés comme « sans logis » les personnes ne disposant pas des conditions sociales, économiques ou personnelles requises pour accéder à un logement et qui, de ce fait, dorment "dehors", dans une tente, sous un pont, ou dans une habitation construite avec des matériels trouvés dans la ville. En utilisant la méthode ethnographique – observation participante de longue durée, tenue minutieuse d'un carnet de terrain relatant les observations quotidiennes – l’auteur apprend par l’expérience corporelle, « par corps », les difficultés quotidiennes concernant l'hygiène et l'occupation de lieux publics, mais surtout les efforts réalisés pour se soustraire aux sentiments de honte et de « mépris social » et accéder à des formes de reconnaissance marquées par davantage de fierté et d'estime sociale. Contre le « mépris social », les personnes étudiées luttent comme elles peuvent : certaines s'installent dans des « coins » ou aux marges de la ville afin de se rendre peu visibles ; d'autres s'efforcent d'effacer toutes traces de précarité sur leurs corps; d'autres encore rejoignent la manifestation des Enfants de Don Quichotte de l'hiver 2006 à Paris. Dans ces parcours, allant de la survie à la reconnaissance, les personnes donnent à voir et penser les logiques de domination à la fois morales, corporelles et cognitives qui caractérisent leur statut social

Uma filosofia para o Brasil: A identidade nacional brasileira em A estética da vida
No full textThis article aims to analyze how the writer José Pereira da Graça Aranha represented the Brazilian national identity in the set of essays The aesthetics of life, published in 1921. José Pereira da Graça Aranha (1868-1931), born in São Luís do Maranhão, Brazilian writer and diplomat, graduated in Law from the Recife Law School. Graça Aranha was concerned with defining what it meant to be Brazilian. In an attempt to address this issue, he elaborated to explain what constituted the Brazilian being and the reasons for having such characteristics. He publicized his projects through publications, which included texts such as essays, novels, among others. The Aesthetic work of life is formed by a set of essays, among which Aranha exposes her philosophical conceptions of the world, presenting the view that each people has its own characteristic that would form the soul of the race. For Aranha, each nation would integrate the universal whole through its uniqueness. In this work the author explains how this whole would be formed and how Brazil could find its characteristic to integrate it, defending the conservation of Portuguese characteristics and the political union of Brazil and Portugal.Este artigo têm o objetivo de analisar de que maneira o escritor José Pereira da Graça Aranha representou a identidade nacional brasileira no conjunto de ensaios A estética da vida, publicado em 1921. José Pereira da Graça Aranha (1868- 1931), natural de São Luís do Maranhão, escritor e diplomata brasileiro, formou-se em Direito pela Faculdade de Direito do Recife. Graça Aranha preocupou-se em definir o que significava ser brasileiro. Na tentativa de sanar essa questão, elaborou procurou explicar o que constituía o ser brasileiro e os motivos de se ter tais características. Divulgou seus projetos através de publicações, que compreendiam textos como ensaios, romances, entre outros. A obra Estética da vida é formada por um conjunto de ensaios, dentre os quais Aranha expõe suas concepções filosóficas de mundo, apresentando a visão de que cada povo tem uma característica própria que formaria a alma da raça. Para Aranha, cada nação integraria o todo universal através de sua singularidade. Nessa obra o autor explica como seria formado esse todo e de que maneira o Brasil poderia encontrar sua característica para integrá-lo, trazendo também sua explicação de pátria e nação. Para o estudo, vamos perceber como Aranha utilizou os ideais do determinismo racial e demográfico, o conceito de nação que apresentou, além do contexto da escrita e as principais ideias que influenciaram a produção dos ensaios.
