Interações digitais : uma proposta de ensino de radiojornalismo por meio das TIC / Digital interactions : a teaching radiojournalism proposal mediated by ICT

Tonus, Mirna 12 August 2018 (has links)
Acompanha 1 CD-ROM / Orientador: Jose Armando Valente / Tese (doutorado) - Universidade Estadual de Campinas, Instituto de Artes / Made available in DSpace on 2018-08-12T09:43:21Z (GMT). No. of bitstreams: 1 Tonus_Mirna_D.pdf: 2485563 bytes, checksum: 4314568417f46f70cc65fd3e9ce62375 (MD5) Previous issue date: 2007 / Resumo: O radiojornalismo atual tem requisitado uma nova formação, voltada à edição digital, frente às exigências da atividade profissional. Para concretizá-la, é necessário recorrer às tecnologias da informação e da comunicação (TIC), empregando-as como dispositivo de interação com os aprendizes e de interatividade entre eles e a máquina, o que inclui o desenvolvimento de habilidades para lidar com computadores, softwares e, especificamente, com o áudio digital. Este é o foco desta tese, que traça um dos caminhos possíveis para essa formação, tratando dos cenários científico e documentarista aplicados no radiojornalismo, a partir de teorias da aprendizagem envolvendo o aprender fazendo de Piaget, a zona proximal de desenvolvimento (ZPD) de Vygotsky, a construção social do conhecimento de Freire, e o ciclo de ações e a espiral de aprendizagem de Valente. Com base em pesquisa-ação junto a estudantes de Jornalismo da Universidade de Sorocaba (Uniso), a tese apresenta uma análise de similaridade e implicativa, evidenciando que o processo de aprendizagem é auxiliado com o uso das TIC em uma proposta de formação plurimodal, utilizando elementos da educação presencial e da educação a distância (EAD). / Abstract: The contemporary radiojournalism requests a new formation, directed to the digital edition, because of the requirements of the professional activity. To materialize it, it's necessary to appeal to the information and communication technologies (ICT), using them as device of interaction with the apprenticees and interactivity between them and the machine, what includes the development of abilities to deal with computers, softwares and, specifically, with digital audio one. This is the focus of this thesis, that traces one of the possible ways for this formation, treating to the scientific and documentarist scenes applied in the radiojournalism, from learning theories involving learning by doing of Piaget, the zone of proximal development (ZPD) of Vygostky, social construction of the knowledge of Freire, and the actions cycle and learning spiral of Valente. On the basis of action-research with Journalism students at University of Sorocaba (Uniso), the thesis presents a similarity and implicative analysis, evidencing that the learning process is assisted with the use of ICT in a proposal of plural mode education, using traditional and distance education elements. / Doutorado / Doutor em Multimeios

An investigation of parameter relationships in a high-speed digital multimedia environment

Chigwamba, Nyasha January 2014 (has links)
With the rapid adoption of multimedia network technologies, a number of companies and standards bodies are introducing technologies that enhance user experience in networked multimedia environments. These technologies focus on device discovery, connection management, control, and monitoring. This study focused on control and monitoring. Multimedia networks make it possible for devices that are part of the same network to reside in different physical locations. These devices contain parameters that are used to control particular features, such as speaker volume, bass, amplifier gain, and video resolution. It is often necessary for changes in one parameter to affect other parameters, such as a synchronised change between volume and bass parameters, or collective control of multiple parameters. Thus, relationships are required between the parameters. In addition, some devices contain parameters, such as voltage, temperature, and audio level, that require constant monitoring to enable corrective action when thresholds are exceeded. Therefore, a mechanism for monitoring networked devices is required. This thesis proposes relationships that are essential for the proper functioning of a multimedia network and that should, therefore, be incorporated in standard form into a protocol, such that all devices can depend on them. Implementation mechanisms for these relationships were created. Parameter grouping and monitoring capabilities within mixing console implementations and existing control protocols were reviewed. A number of requirements for parameter grouping and monitoring were derived from this review. These requirements include a formal classification of relationship types, the ability to create relationships between parameters with different underlying value units, the ability to create relationships between parameters residing on different devices on a network, and the use of an event-driven mechanism for parameter monitoring. These requirements were the criteria used to govern the implementation mechanisms that were created as part of this study. Parameter grouping and monitoring mechanisms were implemented for the XFN protocol. The mechanisms implemented fulfil the requirements derived from the review of capabilities of mixing consoles and existing control protocols. The formal classification of relationship types was implemented within XFN parameters using lists that keep track of the relationships between each XFN parameter and other XFN parameters that reside on the same device or on other devices on the network. A common value unit, known as the global unit, was defined for use as the value format within value update messages between XFN parameters that have relationships. Mapping tables were used to translate the global unit values to application-specific (universal) units, such as decibels (dB). A mechanism for bulk parameter retrieval within the XFN protocol was augmented to produce an event-driven mechanism for parameter monitoring. These implementation mechanisms were applied to an XFN-protocol-compliant graphical control application to demonstrate their usage within an end user context. At the time of this study, the XFN protocol was undergoing standardisation within the Audio Engineering Society. The AES-64 standard has now been approved. Most of the implementation mechanisms resulting from this study have been incorporated into this standard.

Connection management applications for high-speed audio networking

Sibanda, Phathisile 12 March 2008 (has links)
Traditionally, connection management applications (referred to as patchbays) for high-speed audio networking, are predominantly developed using third-generation languages such as C, C# and C++. Due to the rapid increase in distributed audio/video network usage in the world today, connection management applications that control signal routing over these networks have also evolved in complexity to accommodate more functionality. As the result, high-speed audio networking application developers require a tool that will enable them to develop complex connection management applications easily and within the shortest possible time. In addition, this tool should provide them with the reliability and flexibility required to develop applications controlling signal routing in networks carrying real-time data. High-speed audio networks are used for various purposes that include audio/video production and broadcasting. This investigation evaluates the possibility of using Adobe Flash Professional 8, using ActionScript 2.0, for developing connection management applications. Three patchbays, namely the Broadcast patchbay, the Project studio patchbay, and the Hospitality/Convention Centre patchbay were developed and tested for connection management in three sound installation networks, namely the Broadcast network, the Project studio network, and the Hospitality/Convention Centre network. Findings indicate that complex connection management applications can effectively be implemented using the Adobe Flash IDE and ActionScript 2.0.

Recording classical music in Britain : the long 1950s

Curran, Terence William January 2015 (has links)
During the 1950s the experience of recording was transformed by a series of technical innovations including tape recording, editing, the LP record, and stereo sound. Within a decade recording had evolved into an art form in which multiple takes and editing were essential components in the creation of an illusory ideal performance. The British recording industry was at the forefront of development, and the rapid growth in recording activity throughout the 1950s as companies built catalogues of LP records, at first in mono but later in stereo, had a profound impact on the music profession in Britain. Despite this, there are few documented accounts of working practices, or of the experiences of those involved in recording at this time, and the subject has received sparse coverage in academic publications. This thesis studies the development of the recording of classical music in Britain in the long 1950s, the core period under discussion being 1948 to 1964. It begins by considering the current literature on recording, the cultural history of the period in relation to classical music, and the development of recording in the 1950s. Oral history informs the central part of the thesis, based on the analysis of 89 interviews with musicians, producers, engineers and others involved in recording during the 1950s and 1960s. The thesis concludes with five case studies, four of significant recordings - Tristan und Isolde (1952), Peter Grimes (1958), Elektra (1966-67), and Scheherazade (1964) - and one of a television programme, The Anatomy of a Record (1975), examining aspects of the recording process. The thesis reveals the ways in which musicians, producers, and engineers responded to the challenges and opportunities created by advances in technology, changing attitudes towards the aesthetics of performance on record, and the evolving nature of practices and relationships in the studio. It also highlights the wider impact of recording on musical practice and its central role in helping to raise standards of musical performance, develop audiences for classical music, and expand the repertoire in concert and on record.

Sounds Themselves: Intersections of Serialism and Musique Concrète in Karlheinz Stockhausen's "Elektronische Studie I"

Huff, David, 1976- 08 1900 (has links)
In the summer of 1953, Karlheinz Stockhausen began composing his first piece of elektronische Musik at the Westdeutscher Rundfunk Studio for Electronic Music in Cologne. Up to that point, Stockhausen's only experience with electroacoustic music was his time spent at the Radiodiffusion-Télévision Française the previous year, where he assisted Pierre Schaeffer and composed a piece of musique concrète. An early case study in the marriage of serial aesthetics and electroacoustic techniques, Studie I is a rigorously organized work that reflects Stockhausen's compositional philosophy of a unified structural principle in which all musical materials and parametric values are generated by and arranged according to a single governing series. In spite of this meticulously wrought serial structure, Studie I displays features that are the consequences of the realities of electronic sound production either imposing on the sonic result, or altering the compositional plan entirely. I use a three-part approach to my analysis of Studie I by examining Stockhausen's serial system, the electroacoustic studio techniques in use in 1953, and the original recorded realization through spectrographic analysis. Using this methodology, I expose the blurring of the supposed divide between elektronische Musik and musique concrète by exploring the features that lie between the serial plan and the technical processes Stockhausen used to realize Studie I.

Las nuevas tecnologías en la administración de justicia. La validez y eficacia del documento electrónico en sede procesal

Jaume Bennasar, Andrés 09 October 2009 (has links)
La tesis se encarga de analizar, por un lado, la integración y el desarrollo de las nuevas tecnologías en la Administración de Justicia; y, por otro, los parámetros que constituyen la validez y eficacia del documento electrónico. La primera cuestión se centra en la configuración de los Sistemas de Información de la Oficina Judicial y del Ministerio Fiscal, así como de la informatización de los Registros Civiles, donde el art. 230 LOPJ es la pieza clave. Se estudian sus programas, aplicaciones, la videoconferencia, los ficheros judiciales y las redes de telecomunicaciones que poseen la cobertura de la firma electrónica reconocida, donde cobran gran relevancia los convenios de colaboración tecnológica. La digitalización de las vistas quizá sea una de las cuestiones con más trascendencia, teniendo en cuenta que el juicio es el acto que culmina el proceso. Aunque no todos los proyectos adoptados en el ámbito de la e.justicia se han desarrollado de forma integral, ni han llegado a la totalidad de los órganos judiciales. El objetivo final es lograr una Justicia más ágil y de calidad, a lo cual aspira el Plan Estratégico de Modernización de la Justicia 2009-2012 aprobado recientemente.En referencia a la segunda perspectiva, no cabe duda que el Ordenamiento jurídico y los tribunales, en el ámbito de la justicia material, otorgan plena validez y eficacia al documento electrónico. Nuestra línea de investigación se justifica porque cada vez son más los procesos que incorporan soportes electrónicos de todo tipo, ya sea al plantearse la acción o posteriormente como medio de prueba (art. 299.2 LEC). Entre otros temas examinamos el documento informático, la problemática que rodea al fax, los sistemas de videograbación y el contrato electrónico. / La tesi s'encarrega d'analitzar, per una part, la integració i el desenvolupament de les noves tecnologies dins l´Administració de Justícia; i, per l'altra, els paràmetres que constitueixen la validesa i l'eficàcia del document electrònic. La primera qüestió es centra en la configuració dels Sistemes d´Informació de l´Oficina Judicial i del Ministeri Fiscal, així com de la informatització dels Registres Civils, on l'art. 230 LOPJ es la peça clau. S'estudien els seus programes, aplicacions, la videoconferència, el fitxers judicials i les xarxes de telecomunicacions que tenen la cobertura de la firma electrònica reconeguda, on cobren gran rellevància els convenis de col·laboració tecnològica. La digitalització de les vistes tal vegada sigui una de les qüestions amb més transcendència, tenint amb compte que el judici es l'acte que culmina el procés. Però no tots el projectes adoptats en l'àmbit de la e.justicia s'han desenvolupat d'una manera integral ni han arribat a la totalitat dels òrgans judicials. L'objectiu final es assolir una Justícia més àgil i de qualitat, al que aspira el Pla Estratègic de Modernització de la Justícia 2009-2012 aprovat recentment. En referència a la segona perspectiva, no hi ha dubte que l´Ordenament jurídic i els tribunals, en l'àmbit de la justícia material, donen plena validesa i eficàcia al document electrònic. La nostra línia d'investigació es justifica perquè cada vegada son més el processos que incorporen suports electrònics de tot tipus, ja sigui quant es planteja l'acció o posteriorment como a medi de prova (art. 299.2 LEC). Entre altres temes examinem el document informàtic, la problemàtica que envolta al fax, els sistemes de videogravació i el contracte electrònic. / The thesis seeks to analyse, on the one hand, the integration and development of the new technologies in the Administration of Justice; and, on the other, the parameters which constitute the validity and efficiency of the electronic document.The first question centres on the configuration of the Information Systems of the Judicial Office and the Public Prosecutor, as well as the computerisation of the Civil Registers, where the art. 230 LOPJ it's the part key. Their programmes, applications, the Video Conferencing, the judicial registers and the telecommunication networks which are covered by the recognised electronic signatures, are studied, where the agreements on technological collaboration gain great relevance. The digitalisation of evidence might perhaps be one of the questions with most consequence, bearing in mind that the judgment is the act by which the process is culminated. Although not all the projects adopted within the compass of e.justice have developed completely nor have reached all the judicial organs. The final objective is to achieve an agile, quality Justice, to which the recently approved Strategic Plan for the Modernisation of Justice aspires.With reference to the second perspective, there is no doubt that the juridical Ordinance and the tribunals within the compass of material justice grant full validity and efficacy to the electronic document. Our line of investigation is justified because there are more and more processes which are sustained by electronic supports of all kinds, whether it be at the establishment of the action or later, as a proof of it (art. 299.2 LEC). Amongst other things, we examine the computerised document, the problems which surround the fax, the systems for video recording and the electronic contract.
