Collusion et possibilité d’entrée en aval dans une industrie verticalement intégrée
Authors: Avenel Éric , Caprice Stéphane 
Published: January 2018

L’article revisite la question de la soutenabilité d’une entente en présence d’une menace d’entrée dans un contexte où les firmes en place sont verticalement intégrées. Les entrants dépendent des firmes intégrées pour leurs approvisionnements. Alors que l’entrée laisse les profits de collusion inchangés, nous montrons que les profits de déviation sont également inchangés et que l’entrée abaisse les profits dans les périodes de punition. En ce sens, la possibilité d’entrée facilite la collusion entre les firmes intégrées. Classification JEL : D43, L13, L23, L40.
Transition écologique et numérique. Vers des territoires communs ?
Authors: Petit Victor 
Published: January 2018

Cet article se propose de réfléchir à la possibilité de réunir transition numérique et transition écologique, tout en prenant acte du fait que l’impact environnemental des Tic est désastreux. Une opposition conceptuelle sera proposée (écologie de l’environnement/écologie du milieu) dans le but d’éclairer l’ambivalence du rapport entre Tic et écologie. Le but de cet article est de donner à lire l’engouement actuel pour les « communs » comme la possibilité de relier ces deux transitions. À travers un certain nombre d’exemples, nous montrerons que la dynamique qui s’opère autour de ce concept est susceptible de devenir le milieu d’une expérimentation territoriale inédite.
Multivariate Rankin–Selberg Integrals on GL4 and GU(2, 2)
Authors: Pollack Aaron , Shah Shrenik 
Published: January 2018

AbstractInspired by a construction by Bump, Friedberg, and Ginzburg of a two-variable integral representation on GSp4 for the product of the standard and spin L-functions, we give two similar multivariate integral representations. The first is a three-variable Rankin–Selberg integral for cusp forms on PGL4 representing the product of the L-functions attached to the three fundamental representations of the Langlands L-group SL4(C). The second integral, which is closely related, is a two-variable Rankin–Selberg integral for cusp forms on PGU(2, 2) representing the product of the degree 8 standard L-function and the degree 8 exterior square L-function.

Abstract. Asian dust has been reported to carry anthropogenic reactive nitrogen during transport from source areas to the oceans. In this study, we attempted to characterize NH4+ and NO3− in atmospheric particles collected at a coastal site in northern China during spring dust events from 2008 to 2011. Based on the mass concentrations of NH4+ and NO3− in each total suspended particle (TSP) sample, the samples can be classified into increasing or decreasing types. In Category 1, the concentrations of NH4+ and NO3− were 20–440 % higher in dust day samples relative to samples collected immediately before or after a dust event. These concentrations decreased by 10–75 % in the dust day samples in Categories 2 and 3. Back trajectory analysis suggested that multiple factors, such as the transport distance prior to the reception site, the mixing layer depth on the transport route and the residence time across highly polluted regions, might affect the concentrations of NH4+ and NO3−. NH4+ in the dust day samples was likely either in the form of ammonium salts existing separately to dust aerosols or as the residual of incomplete reactions between ammonium salts and carbonate salts. NO3− in the dust day samples was attributed to various formation processes during the long-range transport. The positive matrix factorization (PMF) receptor model results showed that the contribution of soil dust increased from 23 to 36 % on dust days, with decreasing contributions from local anthropogenic inputs and associated secondary aerosols. The estimated deposition flux of NNH4++NO3− varied greatly from event to event; e.g., the dry deposition flux of NNH4++NO3− increased by 9–285 % in Category 1 but decreased by 46–73 % in Category 2. In Category 3, the average dry deposition fluxes of particulate nitrate and ammonium decreased by 46 % and increased by 10 %, respectively, leading to 11–48 % decrease in the fluxes of NNH4++NO3−.

Abstract. This paper presents the operational cloud retrieval algorithms for
the TROPOspheric Monitoring Instrument (TROPOMI) on board the European Space
Agency Sentinel-5 Precursor (S5P) mission scheduled for launch in 2017. Two algorithms working in tandem are used for retrieving cloud properties:
OCRA (Optical Cloud Recognition Algorithm) and ROCINN (Retrieval of Cloud
Information using Neural Networks). OCRA retrieves the cloud fraction using
TROPOMI measurements in the ultraviolet (UV) and visible (VIS) spectral regions, and ROCINN retrieves the
cloud top height (pressure) and optical thickness (albedo) using TROPOMI
measurements in and around the oxygen A-band in the near infrared (NIR). Cloud parameters from TROPOMI/S5P will be used not only for enhancing the
accuracy of trace gas retrievals but also for extending the satellite data
record of cloud information derived from oxygen A-band measurements, a record
initiated with the Global Ozone Monitoring Experiment (GOME) on board the second European Remote-Sensing Satellite (ERS-2) over 20 years ago. The OCRA and ROCINN algorithms are integrated in the S5P operational
processor UPAS (Universal Processor for UV/VIS/NIR Atmospheric
Spectrometers), and we present here UPAS cloud results using the Ozone Monitoring Instrument (OMI) and GOME-2
measurements. In addition, we examine anticipated challenges for the
TROPOMI/S5P cloud retrieval algorithms, and we discuss the future validation
needs for OCRA and ROCINN.
Scenes, Quarters and Clusters: the Formation and Governance of Creative Places in Urban China
Authors: Wen Wen 
Published: January 2018

Abstract
This paper presents a PhD program examining the formation and governance patterns of the social and spatial concentration of creative people and creative businesses in cities. It develops a typology for creative places, adding the terms ‘scene’ and ‘quarter’ to ‘clusters’, to fill in the literature gap of partial emphasis on the ‘creative clusters’ model as an organising mechanism for regional and urban policy.
The framework is then applied to China, specifically to Hangzhou, a second-tier city in central eastern China that is ambitious to become a ‘national cultural and creative industries centre’. Drawing on in-depth interviews with initiators, managers and creative professionals from three cases selected respectively for scene, quarter and cluster, together with extensive documentary analysis, the paper investigates the composition of actors, characteristics of the locality and the diversity of activities of the three places. The findings demonstrate a convergence of the three terms. Furthermore, in China, planning and government intervention is the key to the governance of creative places; spontaneous development processes exist, but these need a more tolerant environment, a greater diversity of cultural forms and more time to develop. Moreover, the main business development model is still real estate based: this model needs to incorporate more mature business models and an enhanced IP protection system. Finally, the business strategies need to be combined with a self-management model for the creative class, and a collaborative governance mechanism with other stakeholders such as government, real estate developers and education providers.
Co-creative Media in Remote Indigenous Communities
Authors: Rennie Ellie 
Published: January 2018

Abstract
This paper examines co-creative video outputs that have originated from, or relate to, remote Indigenous communities in Australia. Scholarly work on remote media has mostly operated at the interface of media studies and anthropology, seeking to identify how cultural systems shape the production, distribution and reception of media in Aboriginal communities. This paper looks instead at content themes, funding sources and institutions during the 2010-2013 period, and examines the factors that may be determining the quantity of co-creative outputs, as well as the types of stories that get produced. I argue that the focus on culture has obscured important shifts in remote media policy and funding, including a trend towards content designed to address social disadvantage.
Co-Creating Knowledge Online: Approaches for Community Artists
Authors: Shea Pip 
Published: January 2018

Abstract
Forming peer alliances to share and build knowledge is an important aspect of community arts practice, and these co-creation processes are increasingly being mediated by the Internet. This paper offers guidance for practitioners who are interested in better utilising the Internet
The decision not to capitalise the word ‘internet’ in this paper is based on the consideration that digital networks that use the Internet protocol suite, TCP/IP, have become ubiquitous means of sending and receiving communications.
to connect, share, and make new knowledge. It argues that new approaches are required to foster the organising activities that underpin online co-creation, building from the premise that people have become increasingly networked as individuals rather than in groups (Rainie & Wellman 2012: 6), and that these new ways of connecting enable new modes of peer-to-peer production and exchange. This position advocates that practitioners move beyond situating the Internet as a platform for dissemination and a tool for co-creating media, to embrace its knowledge collaboration potential.
Drawing on a design experiment I developed to promote online knowledge co-creation, this paper suggests three development phases – developing connections, developing ideas, and developing agility – to ground six methods. They are: switching and routing, engaging in small trades of ideas with networked individuals; organising, co-ordinating networked individuals and their data; beta-release, offering ‘beta’ artifacts as knowledge trades; beta-testing, trialing and modifying other peoples ‘beta’ ideas; adapting, responding to technological disruption; and, reconfiguring, embracing opportunities offered by technological disruption. These approaches position knowledge co-creation as another capability of the community artist, along with co-creating art and media.
Community Media 2.0: A Report from the ‘Co-Creative Communities’ Forum
Authors: Edmond Maura 
Published: January 2018

Abstract
Participatory digital culture presents major challenges to all traditional media outlets, but it presents very direct challenges to the community broadcast sector, which was established from the outset as local, community-driven and participatory. These and other issues were the focus of a recent forum at the Australian Centre for the Moving Image in Melbourne (Co-Creative Communities, 8–9 November 2012). The forum was part of a national research project, which has been exploring how Australian community arts and media organisations are responding to participatory digital culture, social media and user-led innovation. Focusing on the organisations that presented at the symposium, the paper examines how community-interest media is making the most of new and social media platforms. It considers examples of participatory digital media that have emerged from the community broadcast sector, but it also considers local, collaborative, community-interest media projects developed by public broadcasters and organisations involved in arts, social justice and development. Drawing on forum transcripts and follow-up research the essay describes some of the key trends shaping how community-interest media organisations and independent producers are working with participatory digital culture, and with what success.
What’s in a Name? On Language, Concept Formation, and the Definition Disputes in the Entrepreneurship Literature
Authors: Jonsson Petur O. 
Published: January 2018

Abstract
When it comes to entrepreneurship, the conceptual framework of economics is disjointed: On the one hand almost everyone agrees that entrepreneurial initiative and creativity are critical for economic progress. On the other hand neither initiative, nor creativity, plays any role in formal models of choice and economic behavior. This creates a blind spot on the behavioral aspects of entrepreneurship. It has also spawned a dichotomy between the functional and behavioral aspects of entrepreneurial actions in the economics literature. Most importantly, it prevents economists from developing a coherent unifying theoretical framework for making sense of entrepreneurs. The problem is reinforced by the language and semiotics of economics and is reflected by the lack of behavioral research on entrepreneurs in the literature. As suggested by Baumol (1968 and 2010) initiative and creativity are the obvious defining traits of entrepreneurship. Even so, the literature has spawned a variety of different and occasionally nonsensical definitions of entrepreneurship that obscure and divert our attention away from these defining characteristics. The divergent definitions in the literature are further exacerbated by discordant conceptual structures and ideas that cannot easily be translated from one field to another. In the absence of a unifying framework, different fields have focused narrowly on entrepreneurship from dissimilar angles. The bottom line is that researchers in different fields sometimes rely on such incompatible definitions of what constitutes entrepreneurship that interdisciplinary dialogue is impossible. The end result is akin to the problem of radical translation between different languages. The paper concludes that the definition debates will not be resolved without a unifying structure that focuses on initiative and creativity as the defining attributes of entrepreneurship. This calls for some new tools and behavioral models that can explicitly account for initiative and creativity as integral aspects of human choices and actions.
Knowledge Unlatched: A Global Library Consortium Model for Funding Open Access Scholarly Books
Authors: Montgomery Lucy 
Published: January 2018

Abstract
This special issue of Cultural Science Journal is devoted to the report of a groundbreaking experiment in re-coordinating global markets for specialist scholarly books and enabling the knowledge commons: the Knowledge Unlatched proof-of-concept pilot. The pilot took place between January 2012 and September 2014. It involved libraries, publishers, authors, readers and research funders in the process of developing and testing a global library consortium model for supporting Open Access books. The experiment established that authors, librarians, publishers and research funding agencies can work together in powerful new ways to enable open access; that doing so is cost effective; and that a global library consortium model has the potential dramatically to widen access to the knowledge and ideas contained in book-length scholarly works.
Learning and intergenerational communication through digital storytelling in the first grades of primary school: Yesteryear Jobs
Authors: Mouchtari Efthalia , Meimaris Michalis , Gouscos Dimitris , Sfyroera Maria 
Published: January 2018

Abstract
The research reported in this paper examines how two different groups, primary schoolchildren and elderly people, could close the generation gap through a digital storytelling-based interaction framework that can result in learning for the younger and intergenerational communication. Yesteryear jobs have been chosen as the theme of this research, based on the premise that, as computers and automated systems increasingly take the jobs humans once held, entire professions become extinct, and some of these endangered professions, from a milkman to an iceman, could become better known to primary school children through storytelling from elderly people. In this respect, the research reported in this paper has combined digital storytelling with techniques as traditional as theatrical games, in order to create a blended framework for intergenerational interactions. The research project was realized in the 15th Primary School of Piraeus, in Athens, Greece during academic years 2011-12 and 2012-13. It has involved a 6-month empirical study and embraced skills such as literature reading, story and song listening, painting, creating digital stories as well as improvising through theatrical games. The evaluation tools for the outcomes of this project comprised a questionnaire, participant observation, informal interviews and a video rubric for evaluating the digital creations of schoolchildren.

Digital Words of Wisdom? Milia (AppleTree), An Online Platform for Digital Storytelling
Authors: Spanoudakis Manolis , Nakou Alexandra , Meliadou Eni , Gouscos Dimitris , Meimaris Michalis 
Published: January 2018

Abstract
This paper introduces Milia (AppleTree), an open online platform for social interactive digital storytelling, which has been developed by the Laboratory of New Technologies in Communication, Education and the Mass Media, with the support of the University Research Institute of Applied Communication (URIAC) of the Faculty of Communication and Media Studies of the University of Athens. The Milia platform aims to support the representation, presentation and collaborative creation of any sort of stories in digital format. Applications of the platform can be found in storytelling per se, in education, in publishing and, more generally, in the creation and publication of collaborative digital works. The first part of the paper is focused on a state of the art review for digital storytelling platforms and discussion of some major challenges that these platforms are attempting to face. This review is followed by a second part, which discusses the technical features and functional capabilities of the Milia platform in detail, and a third part, which reports on applications of the platform that have already been realized and digital stories that are already available online. The paper is concluded with a discussion of limitations and directions of future work for the Milia platform.
Life storytelling at the ABC: Challenges of ‘giving the audience a voice’ in the context of public service media
Authors: Mackay Sasha , Heck Elizabeth 
Published: January 2018

Abstract
Life storytelling projects have become an important means through which public service media institutions such as the Australian Broadcasting Corporation are seeking to foster audience participation and involve particular cohorts in the creation and distribution of broadcast content. This paper contributes to the wider conversation on audience participation within public service media intuitions (PSMs), and focuses on the opportunities and challenges that arise within life storytelling projects that are facilitated by these institutions, and that aim to ‘give voice’ to members of ‘the audience’. In particular, it focuses on two of the Australian Broadcasting Corporation’s current life storytelling projects: ABC Open and Heywire.
Les modalités énonciatives de la reprise du discours d'autrui dans les écrtis de recherche et les écrits didatiques
Authors: Daunay Bertrand , Delcambre Isabelle 
Published: January 2018

<p>L’article vise à décrire les modalités énonciatives des reprises du discours d’autrui effectuées dans des écrits académiques. Sont comparés deux types d’écrit produits par des enseignants-chercheurs : des écrits didactiques, élaborés pour des cours à distance, et des écrits de recherche, à destination de la communauté scientifique. Par modalités énonciatives, il faut entendre les modes de prise en charge, par un énonciateur, d’un discours d’autrui qu’il reprend dans son propre discours. Après avoir présenté leur cadre théorique et la terminologie qu’ils proposent (notamment l’identification de deux pôles, nommés « paraphrase » et « métaphrase »<em>,</em> opposant les modalités énonciatives de la reformulation), les auteurs décrivent leur corpus et leur méthodologie avant de présenter leurs résultats – dont le plus net : la part respective de ces deux modalités diffère selon le contexte de production (écriture d’enseignement ou écriture de recherche).</p><p> </p>
Pratiques de réconciliation au Liban
Authors: Chrabieh Pamela 
Published: January 2018

Bien que les pratiques de réconciliation connaissent une longue histoire au Liban, celles-ci se diversifient à partir des années 1990. Elles constituent un important objet d’étude pour de nombreux académiciens et académiciennes ainsi que chercheurs et chercheuses ; elles sont devenues la cause commune d’une pléthore d’organismes non-gouvernementaux, d’associations civiles, de mouvements sociaux et d’artistes. Le thème de la réconciliation des Libanais et Libanaises sert aussi de cadre pour le discours politique. Cet article présente un état des lieux de ces pratiques en traitant premièrement de la relation de la réconciliation au dialogue interreligieux puis de la relation de la réconciliation à la mémoire nationale. Il présente par la suite certains exemples au sein de la société civile et identifie en conclusion quelques pistes de réflexion.
On the Role of Ionospheric Ions in Sawtooth Events
Authors: Lund E. J. , Nowrouzi N. , Kistler L. M. , Cai X. , Frey H. U. 
Published: January 2018

AbstractSimulations have suggested that feedback of heavy ions originating in the ionosphere is an important mechanism for driving sawtooth injections. However, this feedback may only be necessary for events driven by coronal mass ejections (CMEs), whereas in events driven by streaming interaction regions (SIRs), solar wind variability may suffice to drive these injections. Here we present case studies of two sawtooth events for which in situ data are available in both the magnetotail (Cluster) and the nightside auroral region (FAST), as well as global auroral images (IMAGE). One event, on 1 October 2001, was driven by a CME; the other, on 24 October 2002, was driven by an SIR. The available data do not support the hypothesis that heavy ion feedback is necessary to drive either event. This result is consistent with simulations of the SIR‐driven event but disagrees with simulation results for a different CME‐driven event. We also find that in an overwhelming majority of the sawtooth injections for which Cluster tail data are available, the O+ observed in the tail comes from the cusp rather than the nightside auroral region, which further casts doubt on the hypothesis that ionospheric heavy ion feedback is the cause of sawtooth injections.
