Optical wireless GEO satellite-to-ground downlinks: rateless codes as solution for scintillation fading

2013

Scintillation fading can corrupt a satellite-to-ground optical wireless links with burst errors. Rateless codes, suitable for erasure channel, are able to eliminate or to reduce these communication errors. We analyzed the performances of three different rateless codes in a simulated Geo satellite-to-ground downlink.

Religious confession privilege in Italy

2021

In Italy, the secrecy of confession practised in some religious denominations and especially in the [Roman] Catholic Church, is widely recognised. Indeed, it is so widely recognised that it is not perceived as a particular concession to religion, even less as a privilege, but rather as a to religious freedom guaranteed by art 19 of the Constitution of the Italian (‘Italian Constitution’ or ‘Constitution’) which is a subjective and public right since it can be enforced against the state. In other words, this protection of religious belief and action in the Italian Constitution denies that the state may limit religious confession and the secrecy of that confession by law or administrative act…

Finite Commutative Rings and Their Applications

2002

Finite Commutative Rings and their Applications is the first to address both theoretical and practical aspects of finite ring theory. The authors provide a practical approach to finite rings through explanatory examples, thereby avoiding an abstract presentation of the subject. The section on Quasi-Galois rings presents new and unpublished results as well. The authors then introduce some applications of finite rings, in particular Galois rings, to coding theory, using a solid algebraic and geometric theoretical background.

Creating Digital Musical Instruments With and for Children: Including Vocal Sketching as a Method for Engaging in Codesign

2020

International audience; A class of master of science students and a group of preschool children codesigned new digital musical instruments based on workshop interviews involving vocal sketching, a method for imitating and portraying sounds. The aim of the study was to explore how the students and children would approach vocal sketching as one of several design methods. The children described musical instruments to the students using vocal sketching and other modalities (verbal, drawing, gestures). The resulting instruments built by the students were showcased at the Swedish Museum of Performing Arts in Stockholm. Although all the children tried vocal sketching during preparatory tasks, few …

Codesigning technology for a voluntary-sector organization

2019

© 2019 Khushnood Naqshbandi, Simon Hoermann, David Milne, Dorian Peters, Benjamin Davies, Sophie Potter, & Rafael A. Calvo. This paper presents an investigation into the experiences and perceptions of volunteers and community managers of an Australian voluntary-sector organization that supports young help-seeking people. The process focused specifically on the design of a chat tool, a rudimentary version of which was conceptualized and tested during a trial completed prior to this study. The process explored the motivations and experiences of these volunteers using a codesign approach, which led to the development of specific features of the chat tool that were tailored to the nature of the…

Transparency for Sponsored Content : Analysing Codes of Ethics in Public Relations, Marketing, Advertising and Journalism

2016

As sponsored content is gaining ground globally, the boundaries between strategic communication, advertising and journalism are blurring. As sponsored content becomes more common, it raises novel ethical concerns that no industry alone can answer, such as How much disclosure is needed for transparency? Self-regulation via codes of ethics has been suggested as a remedy to meet the rising transparency expectations, and this article analysed 40 codes of ethics in the fields of communication, advertising, and journalism (United States and Finland) related to sponsored content. The results indicate that there remains excessive variation within the codes of ethics of how transparency of sponsored…

Codeswitching in the comedy of George Lopez

2011

This paper explores the intersectionality of language, culture and identity in the performance of a U.S.-born bilingual Spanish-English speaking comedian, George Lopez. Codeswitches in his comedy are examined through the speaker’s relationship to the audience using Bell’s (1984) theory of audience design. Two specific performances with two distinct audiences are compared using the following questions: How does a bilingual comedian, Lopez, use language mixing to underscore his Latino identity? How does he construct his audience through his choice of codes? How and when does he accommodate monolingual English speaking audiences? I conclude that Lopez intentionally matches his code choice to c…

Dans quelle mesure les préférences individuelles contraignent-elles le développement du marché de l'assurance dépendance ?

2015

Dans un contexte de vieillissement de la population, différents scenarii sont envisagés pour réformer l’organisation et le financement de la prise en charge des personnes âgées dépendantes. La place de la prévoyance individuelle dans le financement de la dépendance est à ce titre largement débattue. À l’heure actuelle, malgré des restes à charge potentiellement conséquents, peu d’individus disposent d’une couverture assurantielle. Cet article vise à enrichir la littérature existante en évaluant dans quelle mesure les préférences observées dans la population limitent cette couverture. Nous mobilisons pour cela l’enquête Patrimoine et préférences vis-à-vis du temps et du risque (Pater) de 201…
