Dissensi espliciti e dissimulazioni mancate. Miscredenza e forme del discorso eterodosso in età moderna

The essay examines the features of religious dissent – particularly in the form of unbelief – in Venice between the mid-seventeenth century and the 1740s. The period witnessed continuous overlapping between fragments of theories, ideas, convictions, which had lost most of their connections with the Protestant faith, and acquired a life of their own. Rather than identifying principles as genetically belonging to one or another tradition of nonconformity, thus, it becomes important to verify how different forms of cultural unrest met and entwine one another in a grey area: their traits blurred according to a dynamic logic of communication; individual elaboration stood out as the outcome of interpersonal interaction. Interaction and public communication is precisely what characterized a form of dissent that appears to have been loud rather than measured; dissimulation predominantly took the form of a selection of places and moments in which “rebel” discourses could go public: the ostentation of diversity was instrumental to the creation of a social identity. Debates worked therefore as stages somehow depriving of responsibility, free spaces of expression, in which theological-political contest marked a free zone where the discussion and presentation of beliefs and issues, even daring ones and for pleasure’s sake, was possible.

A user-centric network communication broker for multimedia collaborative computing

The development of collaborative multimedia applications today follows a vertical development approach, where each application is built on top of low-level network abstractions such as the socket interface. This stovepipe development process is a major inhibitor that drives up the cost of development and slows down the innovation pace of new generations of communication applications. In this paper, we propose a network communication broker (NCB) that provides a unified higher-level abstraction for the class of multimedia collaborative applications. We demonstrate how NCB encapsulates the complexity of network-level communication control and media delivery, and expedites the development of applications with various communication logics. We investigate the minimum necessary requirements for the NCB abstraction. We identify that the concept of user-level sessions involving multiple parties and multiple media, is critical to designing a reusable NCB to facilitate next-generation multimedia communications. Furthermore, the internal design of NCB decouples the user-level sessions from network-level sessions, so that the NCB framework can accommodate heterogeneous networks, and applications can be easily ported to new network environments. In addition, we demonstrate how the extensible and self-managing design of NCB supports dynamic adaptation in response to changes in network conditions and user requirements.

FPGA and USB based control board for quantum random number generator

The design and implementation of FPGA-and-USB-based control board for quantum experiments are discussed. The usage of quantum true random number generator, control- logic in FPGA and communication with computer through USB protocol are proposed in this paper. Programmable controlled signal input and output ports are implemented. The error-detections of data frame header and frame length are designed. This board has been used in our decoy-state based quantum key distribution (QKD) system successfully.

Refining Reflections about Information-Communication ICTs and social logics of communication

This review follows the trail of thought of a book by Bernard Miege, in which the author proposes to analyze technical developments trough its social determination. He reasserts, with his examination, the conception that the technical dimension is constituted, equally, by social logics of communication., which encounter technical objects and in them precipitate as sediment.

NGOs and GMOs

This article seeks to understand how and why we find local NGOs performing a role as alternative science communicators in the social conflict concerning agricultural biotechnology. First, a literature review points out that in the face of modernisation risks techno-scientific development has become contradictory, an evolution exemplified as well as driven by interdisciplinary antagonisms. This creates opportunities for a scientifically supported public critique of science and technology by new social move ments. In addition, the commercialisation of science has brought forward a “science-industrial complex” united by economic interests in the promotion of biotechnology on the one hand, and has contributed to a practice of science communication using the logic of public relations and corporate communication on the other. Once institutional science communication becomes hard to distinguish from corporate communication, NGOs are found to contest and reframe scientific knowledge by aiming at instigating epistemic shifts in institutionalised scientific conceptions and discursive changes in the social values underlying science. Second, I report on the findings of six in-depth interviews with spokespersons for these NGOs, the aim being to achieve an understanding of how these NGOs make sense of their encounters with science in the GM debate and how they situate themselves in their role as alternative science communicators. Finally, I conclude by making some recommendations for journalism in general and science journalism in particular.

La mise en exposition de l’alimentation : L’exemple de l’Alimentarium de Vevey

The article begins with thoughts on general museology, then presents and analyses several tangible creations : two permanent and three temporary «museo-food» exhibitions at the Alimentarium Food Museum in Vevey Switzerland. Food proves to be an excellent subject matter to demonstrate the theory and logic of museum communication. It always comes back to its cultural context. The author uses examples of exhibitions and various interactive educational demonstrations and workshops to consider the possibilities and limitations of the science of museology. The soup tureen, a key exhibit in the Alimentarium, is presented as a paradigm linking museology theory with practice. Exploring various communication techniques contributed immensely to the remake of the permanent exhibition.

Estrategias de comunicación militar y dinámicas mediáticas ¿dos lógicas contradictorias?

<p style="text-align: justify;">En este artículo se plantea cómo la información sobre un conflicto armado o una guerra está determinada no solamente por factores típicos de la profesión periodística, sino que también intervienen factores específicos de una situación de guerra. En contexto de confrontación armada la dinámica de la comunicación militar explica junto con la lógica mediática el cubrimiento informativo de la confrontación armada por parte de los medios de comunicación. Esto se debe principalmente a que los militares y los grupos armados juegan el papel de <em>fuentes informativas</em> para los medios de comunicación. Mientras que los periodistas se acercan a ellos a fin de informar a la población; para los militares el principal objetivo es ganar la guerra. Por esta razón Moisy (2001, p. 202) afirma que "cuando se trata de operaciones [militares] en el campo de batalla, hay que admitir que las exigencias de transparencia de los medios de comunicación no son compatibles con el afán de eficacia de los ejércitos..."<sup><a id="1" name="1"></a><a href="#1a">1</a></sup>.</p><p style="text-align: justify;"><strong>Palabras clave:</strong> Información, Guerra, Conflicto armado, Lógica de comunicación de guerra, Fuentes informativas, Lógica mediática.</p>

Analysis of k-Neigh topology control protocol for mobile wireless networks

k-Neigh is a basic neighbor-based topology control protocol based on the construction of k-neighbor graph as logical communication graph. Several topological aspects of the constructed topology which are crucial to the performance of the protocol are not yet analytically investigated. Moreover, the problem of determining the maximum Hello interval preserving the connectivity with high probability has not been extensively addressed yet. Since execution of the protocol is a resource consuming task, this problem is of great importance on the performance of the protocol in sense of power consumption and topology control overhead. In this paper, first, several topological properties of the constructed topology for a static network, e.g. average logical degree and average final transmission range, are investigated analytically. Then, temporal properties of the dynamic topology in presence of mobility are studied based on two phenomena, one concerning a connectivity phase transition with time which is reported for the first time and the other one concerning the average degree of the logical communication graph at the time of starting the phase transition defined as disconnection degree. Using the obtained results one may tune the protocol in sense of Hello interval, maximum transmission power, or number of neighbors (k). Although the present work considers k-Neigh protocol, many interesting quantities are derived which may have application beyond the specific problem considered in this paper, e.g. the cdf, mean, and variance of the distance to the ith neighbor.

Realism, logic and social communication: C.S. Peirce's classification of science in communication studies and journalism

The nature of communication study discourse tends to focus on how to teach it, and often hides its pragmatic origins in the field of inquiry. The article uses C.S. Peirce's philosophical realism to address the needs of intellectual inquiry in communications under increasing social and political globalisation. Journalism, media and communication (JMC) studies are treated as institutional functions within a changing, and often shrinking, social realm. I conclude that environments of social and political change offer JMC practitioners a good opportunity for reconceptualising their relationships with other practitioners in the changing social realm of post-modernity.

New communicative challenges: Dundee, place branding and the reconstruction of a city image

This article reviews the expanding literature on city marketing and place branding to explore the strategic dilemmas associated with transforming a negative city image. It conceptualises the emerging communicative logic, which is becoming more evident in the urban regeneration and planning and development discourses. The article puts forward a framework to explain how contemporary theories of city communications can be used to help understand the potential active interplay between the physical (infrastructure) and landscape (urban design, green spaces) dimensions of managing urban change and the governance (structural, organisational) and behavioural (strategic planning and leadership) facets of image communication. These activities can have important effects on how a city is perceived, and can work in tandem with formal and deliberate communicative activities, such as the use of slogans. This conceptualisation is illustrated with reference to Dundee, a relatively small post-industrial city in Scotland, w...

Discursive Institutionalism: The Explanatory Power of Ideas and Discourse

The newest “new institutionalism,” discursive institutionalism, lends insight into the role of ideas and discourse in politics while providing a more dynamic approach to institutional change than the older three new institutionalisms. Ideas are the substantive content of discourse. They exist at three levels—policies, programs, and philosophies—and can be categorized into two types, cognitive and normative. Discourse is the interactive process of conveying ideas. It comes in two forms: the coordinative discourse among policy actors and the communicative discourse between political actors and the public. These forms differ in two formal institutional contexts; simple polities have a stronger communicative discourse and compound polities a stronger coordinative discourse. The institutions of discursive institutionalism, moreover, are not external-rule-following structures but rather are simultaneously structures and constructs internal to agents whose “background ideational abilities” within a given “meaning context” explain how institutions are created and exist and whose “foreground discursive abilities,” following a “logic of communication,” explain how institutions change or persist. Interests are subjective ideas, which, though real, are neither objective nor material. Norms are dynamic, intersubjective constructs rather than static structures.

Servo

Conventional programming models were designed to be used by expert programmers for programming for large-scale multiprocessors, distributed computational clusters, or specialized parallel machines. These models, therefore, are deemed either too difficult for an "average" programmer (who will be expected to do parallel programming in the many-core world) or too inefficient to use for many-core architectures [3]. Similarly, conventional execution models were designed for performance, not scalability. To address the challenge of performance scalability for many-core architectures, we introduce Servo, a Service Oriented programming model that decomposes every program into a set of components (each with its own local memory, mutable state, and a program counter) that either request services or deliver services. Servo is characterized by the decoupling of logical communication mapping between program modules (or services) from physical communication mapping between modules. This allows the services to be migrated and replicated during execution. The proposed model also allows the granularity of data parallel operations to be changed dynamically. This allows runtime variation in the locking granularity which in turn enables higher write-parallelism. Finally, the models partition even data into services. This can significantly enhance locality and makes it possible to have superlinear speedups with increasing number of cores. Our preliminary investigations demonstrate significant performance scalability advantages for Servo.

MPIRace-Check V 1.0: MPI 병렬 프로그램의 메시지경합 탐지를 위한 도구

메시지전달 프로그램에서 발생하는 메시지경합은 프로그램의 비결정적 수행결과를 초래하므로 효과적인 디버깅을 위하여 탐지되어야 한다. 메시지경합을 탐지하는 기존의 도구는 임의의 메시지를 수신하는 모든 사건에서 경합이 발생한다고 보고한다. 그러나 메시지들이 전송되는 논리적인 통신채널이 서로 다르면 임의의 메시지를 수신하는 사건에서 경합이 발생하지 않을 수도 있으므로, 기존 도구의 부정확한 탐지정보는 프로그래머의 디버깅 작업을 더욱 어렵게 한다. 본 논문에서는 메시지 송수신 사건간의 병행성과 메시지들의 논리적 통신채널을 검사하여 보다 정확하게 메시지경합을 탐지하는 도구인 MPIRace-Check를 제안하다. 본 도구는 vector timestamp를 이용하여 프로그램 수행 중에 메시지를 전송하는 송수신 사건들간의 병행성을 검사하고, 메시지 부가정보를 이용하여 메시지들의 논리적인 통신채널이 동일한지를 검사하여 메시지경합을 탐지한다. 실험에서는 MPI_RTED와 벤치마크 프로그램을 이용하여 본 도구가 프로그램 수행 중에 효율적으로 모든 경합을 정확하게 탐지함을 보인다. 따라서 본 도구는 메시지경합을 정확하게 탐지하여 프로그래머의 디버깅 부담을 줄이고 신뢰성이 있는 병렬 프로그램의 개발을 가능하게 한다. Message races should be detected for debugging effectively message-passing programs because they can cause non-deterministic executions of a program. Previous tools for detecting message races report that message races occur in every receive operation which is expected to receive any messages. However message races might not occur in the receive operation if each of messages is transmitted through a different logical communication channel so that their incorrect detection makes it a difficult task for programmers to debug programs. In this paper we suggest a tool, MPIRace-Check, which can exactly detect message races by checking the concurrency between send/receive operations, and by inspecting the logical communication channels of the messages. To detect message races, this tool uses the vector timestamp to check if send and receive operations are concurrent during an execution of a program and it also uses the message envelop to inspect if the logical communication channels of transmitted messages are the same. In our experiment, we show that our tool can exactly detect message races with efficiency using MPI_RTED and a benchmark program. By detecting message races exactly, therefore, our tool enables programmers to develop reliable parallel programs reducing the burden of debugging.

Functionalism and representationalism in contemporary urban agendas: a Scottish perspective on city-region branding

The turn to city-regionalism in Scotland is a consequence of the policy and political assertion of the importance of cities in the new territorial economy of a devolved state. Moreover, the developmental rationale for city-regions rests on the stronger functional realignment of economic growth, investment, housing and population patterns, and the interaction of diverse flows to realise agglomeration efficiencies. In planning and governance terms, the argument for city-regions involves a layered spatial intervention so as to secure intended institutional efficiencies and sustainable development. In practice, the city-region discourse is dominated by functional linkages and relations in factor markets. This paper questions whether this functional perspective is sufficient in socially reconstructing the city-region identity. Adopting the concepts of functionalism and representationalism from the place-branding literature, this paper considers what may be learned from a communicative logic that is relatively more sensitive to issues of interpretation and identity.

Dominating Set Theory based Semantic Overlay Networks for Efficient and Resilient Content Distribution

Recently overlay networks have emerged as an efficient and flexible method for content distribution. An overlay network is a network running on top of another network, usually the Internet. This network is formed by a subset of underlying physical nodes. The connections between the overlay nodes are provided by overlay links, each of which is usually composed of one or more physical link. These networks are employed in many settings to provide logical communication infrastructure over an existing communication networks. The main objective of the overlay network is to reduce routing path lengths, stretched by the overlay routing process. In the existing solutions developed, a kind of fixed infrastructure in the form of excessive message exchange is necessary to guarantee good overlay properties. The scope of our effort is to construct an overlay network based on Dominating Set Theory to optimize the number of nodes for large data transfer. Fast Replica algorithm is applied to reduce the content transfer time for replicating the content within the semantic network. A dynamic parallel access scheme is introduced to download a file from different peers in parallel from the Semantic Overlay Network (SON), where the end users can access the members of the SON at the same time, fetching different portions of that file from different peers and reassembling them locally. That is, the load is dynamically shared among all the peers. To eliminate the need for retransmission requests from the end users, an enhanced digital fountain with Tornado codes is applied. Decoding algorithm at the receiver will reconstruct the original content. In this no feedback mechanisms are needed to ensure reliable delivery. This paper analyzes the performance of sequential unicast, multiple unicast and fast replica with tornado content distribution strategies in terms of content replication time and delivery ratio. This paper also analyzes the impact of dominating set theory for the construction of semantic overlay networks.

Grassrooting Network Imaginaries: Relationality, Power, and Mutual Solidarity in Global Justice Networks

In this paper we draw critically upon actor network theory (ANT) in order to analyse the contours of relationality, communication, and operational logic within a global justice network—People's Global Action Asia. Drawing upon the concept of translation, we consider how connections are fostered and sustained within the network, focusing upon the work of key organisers (those we term the ‘imagineers’) and key events in producing the network. In so doing, we ground ANT in direct political engagement and introduce the concept of ‘grassrooting vectors’ to highlight the power relations at work within global justice networks, a consideration which is crucial to the formation of mutual solidarity between social movements.

Investigation of graph edit distance cost functions for detection of network anomalies

Computer networks are becoming ubiquitous. Accurately monitoring and managing the behaviour of these complex and dynamic networks is a challenging task. It has become crucial to develop and employ good network monitoring techniques that assist in identifying and correcting abnormalities that affect network reliability, performance, security and future planning. There has been significant research in the detection of change and anomalous events in computer networks. A recent novel approach represents the logical communications of a periodically observed network as a time series of graphs and applies the graph matching technique, graph edit distance, to monitor and detect anomalous behaviour in the network. To date, only simple cost functions for graph edit operations have been used in application to computer network monitoring. This article investigates simple normalisation and non-linear techniques in the graph edit distance cost function, to improve detection of specific traffic related network anomalies in the computer network domain.

Run-Time Integration of Reconfigurable Video Processing Systems

Embedded systems in field-programmable gate arrays (FPGAs) can be customized and adaptive if assembled from modular components at run time. This paper examines realizing run-time system assembly by extension of platform-based design. Two major challenges are addressed in this paper. First, the design of a reconfigurable platform architecture suitable for run-time system assembly is described. Different systems are constructed by integrating the platform architecture with different modular components, which employ the communication infrastructure supplied by the platform in order to interact. Second, where on-chip communications channels use shared media, we propose techniques for modeling the intermodule communication behavior based on statistical time-division multiplexing. The proposed techniques enable system designers to guarantee that logical communication requirements between the adjunct modules can be satisfied by the infrastructure. An in-depth analysis is presented and then verified with cycle-accurate simulations for an example reconfigurable platform for real-time video applications.
